What If Deku Had an Overpowered Deinonychus Quirk for Razor Talon Leap Strikes

Humanity had long since grown accustomed to the extraordinary. When the first glowing baby was born in Qing Qing City, the world’s fundamental laws of biology, physics, and society were irrevocably fractured. Over the span of a few generations, the bizarre became the mundane. Fire-breathing, telekinesis, and spontaneous crystallization were cataloged, categorized, and commodified. The era of Quirks had arrived, bringing with it a dawn of superheroes and supervillains.

But nature has a funny way of overcompensating. Sometimes, the genetic lottery didn't just give someone a minor tool or an elemental party trick. Sometimes, the genetic lottery reached deep into the primordial past, bypassing millions of years of human evolution, and pulled out an apex predator.

Izuku Midoriya was four years old when his humanity was violently rewritten.

It didn't happen with a sneeze of fire or a spark of electricity. It happened with a fever that burned so hot Inko Midoriya thought her son was dying. For three days, young Izuku lay in his bed, screaming in agony as his bones quite literally broke and reformed. 

At first, the doctors at the local hospital were baffled. They assumed it was a severe, perhaps fatal, degenerative bone disease. But Dr. Kyudai Garaki, a specialist in Quirk-related mutations, looked at the X-rays and simply told a weeping Inko to wait. "Evolution is rarely a gentle process, Mrs. Midoriya," the doctor had said, his goggles reflecting the harsh fluorescent lights of the clinic. "Your son is not dying. He is adapting."

On the morning of the fourth day, the fever broke. The screaming stopped.

Inko, exhausted and holding a cold compress, gently pushed open Izuku’s bedroom door. "Izuku, baby? How are you feeling—"

She dropped the basin of water. It crashed against the floorboards, water pooling around her slippers, but she didn't notice. She was staring at the foot of the bed.

Izuku was sitting on the edge of his mattress. He looked up at her, his large, emerald eyes wide with a mixture of childlike wonder and confusion. But it wasn't his eyes that made Inko’s breath hitch in her throat. It was his lower half.

Where a young boy’s soft, plantigrade human legs should have been, there was now a pair of heavily muscled, digitigrade limbs. They were covered in smooth, highly durable micro-scales that blended seamlessly into his human skin halfway up his thighs. The anatomy was completely alien to a human being. His heels no longer rested on the ground; instead, they were elevated high up the back of his leg, fundamentally altering his biomechanics. He was balancing perfectly on elongated, powerful toes, making him nearly half a foot taller than he had been three days prior. 

But the most striking, terrifying change lay on his inner toes. From the second digit of each foot protruded a massive, smoothly curved sickle claw. Even on a four-year-old's frame, the keratinous scythes were over three inches long, resting in an elevated, hyper-extended position to keep the tips off the floor. 

Behind him, protruding from the base of his spine, a three-foot-long, muscular reptilian tail swished back and forth in a slow, rhythmic motion, perfectly counterbalancing his new center of gravity.

"Mommy?" Izuku asked, his voice trembling slightly. He hopped off the bed. 

The moment his feet touched the floor, the sheer, unadulterated power of his new anatomy activated. He didn't mean to jump. He just meant to take a step toward her. 

CRACK.

Izuku launched forward with the velocity of a fired cannonball. He slammed into the wooden doorframe next to his mother. In a panic, his legs kicked out reflexively to break his fall. The sickle claw on his right foot snapped downward, locking into place with a sickeningly sharp snikt. 

His foot dragged across the solid oak door. The claw didn't catch or snag. It glided through the three-inch-thick hardwood as if it were warm butter. 

Izuku tumbled onto the hallway carpet, landing gracefully on his hands and new feet, his tail snapping straight out behind him to arrest his momentum. He looked back, tears welling in his eyes. 

The heavy oak bedroom door groaned, shifted, and cleanly slid into two separate pieces, the top half crashing to the floor with a deafening thud. The cut was molecularly smooth. 

Inko fell to her knees, staring at the bisected door, and then at her crying child, who was desperately trying to pull his terrifying claws back off the floor. She didn't scream. She didn't run. She crawled over the ruined door and wrapped her arms around her son, holding him tight as his powerful new tail wrapped anxiously around her waist.

"It's okay, Izuku," she sobbed, burying her face in his messy green curls. "It's okay. Mommy's here. You have a Quirk. You have a Quirk, my sweet boy."

 Ten Years Later

"So, as third-year students, it's time to start thinking seriously about your futures!" 

The homeroom teacher slapped a thick stack of career aptitude papers against his lectern, the sharp smack echoing through the Aldera Junior High classroom. "I'll pass out these printouts for your desired career paths, but let's be honest..." 

The teacher grinned, grabbing the stack of papers and tossing them over his shoulder into the air. "You all want to be heroes, don't you?!"

The classroom erupted. Students leaped from their desks, showing off an array of flashy, mundane, and chaotic Quirks. Fingers elongated, small fires danced across palms, and voices warped into monstrous pitches. It was a cacophony of teenage dreams fueled by a society that worshipped the exceptional.

"Yes, yes, you all have wonderful Quirks," the teacher chuckled, trying to settle the room. "But remember the rules, no Quirk usage in school!"

"Sensei, don't lump me in with these background characters."

The voice cut through the noise like a serrated knife. Sitting near the back of the room, his feet kicked up on his desk, was Katsuki Bakugo. He leaned back, an arrogant smirk plastered across his face, a small string of smoke curling from his fingertips. "They'd be lucky to end up as sidekicks to some busted D-lister. I'm going straight to U.A. High, and then I'm going to surpass All Might himself."

The class erupted into a mix of groans, complaints, and awe. 

"U.A.? The national school? The cutoff score this year is a seventy-nine!"

"I heard they barely accept anyone!"

"That's exactly why it's the only place fit for me," Bakugo scoffed, standing up. "I aced the mock tests. I'm the only one here with the sheer destructive power to stand at the top. I'll be the richest, most famous hero in the world, and it all starts..." 

Bakugo’s crimson eyes slid sideways, looking across the aisle. His smirk faltered for just a fraction of a second, replaced by a subtle, imperceptible tightening of his jaw. "...it all starts by leaving you extras in the dust."

Sitting quietly two rows over, Izuku Midoriya was not participating in the uproar. He sat at a specially modified desk—the bottom half of it had been completely removed to accommodate his unique lower body. 

Izuku didn't look like an extra. He looked like an apex predator doing a very convincing impression of a middle schooler.

His upper body was relatively normal, albeit incredibly lean and corded with tightly wound muscle. He wore the standard Aldera uniform, though his pants were heavily altered, flaring out sharply at the knee to accommodate the massive, inverted-looking joints of his digitigrade legs. Instead of dress shoes, Izuku wore heavily reinforced, custom-made open-toed sandals strapped over dense, scaly reptilian skin. 

Protruding elegantly from a slit in the back of his trousers was his tail. It was nearly four feet long now, thick at the base and tapering to a whiplike point, covered in the same tough, forest-green micro-scales that armored his legs. It moved with a life of its own, currently swaying in slow, methodical arcs behind his chair—a subconscious indicator that Izuku was focused.

Izuku looked up from his notebook, his large green eyes meeting Bakugo’s explosive red ones. 

The classroom held its breath. The dynamic between Midoriya and Bakugo was a known, unspoken law of Aldera Junior High. In any other school, someone with Bakugo’s fiery temper and devastating Quirk would have been a bully, terrorizing the weak. And while Bakugo certainly threw his weight around, he never once laid a hand on Izuku Midoriya. 

It wasn't out of friendship. It was out of a deep, primal wariness. 

When they were seven years old, Bakugo had gotten angry during a game of Heroes and Villains and fired off an explosion at Izuku's face. Izuku hadn't punched back. He hadn't even yelled. His predatory instincts had hijacked his brain. In a blink, Izuku had somersaulted over Bakugo’s head, moving faster than the eye could track. As he flipped, his right sickle-claw had extended, slicing cleanly through the thick steel chains of a nearby swing set before he landed silently in the sandbox. The heavy steel crossbar of the swing had crashed to the ground between them.

Bakugo had stared at the cleanly sheared metal, then at the eight-inch, curved bone-scythe retracting into Izuku’s toe. Izuku had looked just as horrified as Bakugo. But the message had been ingrained in Bakugo’s psyche that day: My explosions can break bones. His claws can sever heads.

They were rivals. An explosive human and a mutant raptor circling each other in an endless, silent turf war.

"Oh, right," the teacher said, adjusting his glasses and looking at his clipboard. "Midoriya, you're also applying for U.A. High's Hero Course, aren't you?"

The silence in the room stretched. No one laughed. A few students actually shifted their desks slightly further away from Izuku.

Izuku slowly closed his notebook—titled Hero Analysis for the Future, Vol. 13. He didn't flinch under the weight of the class's stares. His ears, slightly pointed, twitched at the subtle sound of Bakugo’s breathing hitched just a bit.

"Yes, sir," Izuku said politely. His voice was soft, calm, completely lacking the feral edge his body suggested. "I've already submitted my paperwork for the practical exams."

Bakugo slammed his hand onto his desk, a small explosion cracking like a gunshot. "Hey, Deku."

Izuku slowly turned his head. His eyes locked onto Bakugo’s. "Yes, Kacchan?"

"U.A. doesn't just need raw power. They need heroes," Bakugo growled, leaning over the aisle. The smell of burnt caramel—nitroglycerin sweat—wafted through the air. "Your Quirk ain't built for rescue. It's built for killing. You think the number one hero academy wants a butcher?"

It was a low blow, one that struck at the very core of Izuku's deepest insecurities. But Izuku had spent ten years mastering his emotions, learning to suppress the ferocious instincts that pumped through his veins alongside his blood. If he got angry, he got dangerous. So, he practiced absolute serenity.

Izuku’s tail flicked once. The massive sickle claws on his inner toes remained securely sheathed, raised off the ground. 

"The entrance exam judges villain points, Kacchan," Izuku replied evenly, his voice steady. "Robots don't bleed. And a Quirk is only a tool. A scalpel can save a life in a surgeon's hand, or end one in a murderer's. I'm going to be a hero who saves people with a smile. Just like All Might."

Bakugo scowled, unable to find a flaw in the logic, but fundamentally hating the calm confidence radiating from the boy. He clicked his tongue and sat back down. "Whatever. Just don't get in my way during the exams, or I'll blow those dinosaur legs off."

"I look forward to competing with you, Kacchan," Izuku said gently, turning his attention back to the front of the class.

As the teacher resumed the lesson, Izuku reopened his notebook. But he wasn't looking at the page. He was staring at his own hands. 

Bakugo wasn't entirely wrong. It was the cross Izuku had to bear every single day of his life. 

When he watched videos of All Might saving hundreds of people from disasters, Izuku felt a burning passion in his chest. He wanted to be the Symbol of Peace. He wanted to make people feel safe. But his Quirk—officially registered as Apex Deinonychus—did not want to save people.

His Quirk was a masterpiece of prehistoric evolution, refined for a single purpose: absolute lethality. 

His digitigrade legs acted as high-tension springs, allowing him to leap dozens of meters into the air from a standstill. His dense muscle fibers gave him speed that could outpace a speeding car. His tail provided aerodynamic perfection, allowing him to change direction mid-air by shifting his center of mass. And his claws... his sickle claws were an anatomical nightmare. They were composed of a hyper-dense keratin and enamel matrix, naturally honed to an edge so sharp it could theoretically separate molecules if swung with enough force.

He wasn't a shield. He was a biological scythe. 

To be a hero, Izuku had spent the last decade training himself in the art of extreme restraint. He studied martial arts not to learn how to fight, but to learn how to not kill the things he kicked. He learned to lock his claws upward, utilizing only the dense bone of his heels for blunt-force strikes. He constantly monitored his surroundings, his heightened kinetic vision—a side effect of his predatory brain—tracking every bird, every car, every sudden movement, forcing himself not to pounce.

I will be a hero, Izuku thought, gripping his pencil tightly. I will control the beast. I will be greater than my instincts.

The afternoon sun was casting long, golden shadows across the streets of Musutafu as Izuku walked home. He took the long route, as he often did, enjoying the physical exertion. He didn't walk so much as he bounded, his powerful legs propelling him forward in smooth, loping strides that ate up the pavement. His tail swayed behind him, occasionally dipping low to brush the concrete before sweeping back up into the air.

He was thumbing through his notebook on his phone, analyzing a recent debut by a hero named Kamui Woods. Binding Quirks are highly effective for non-lethal apprehension, Izuku typed rapidly with his thumbs. If I can learn to use my leg strength to pin opponents without striking them, I could simulate a binding effect. Grappling is safer than striking...

His thoughts were violently derailed by a sound.

BOOM.

Izuku stopped dead in his tracks. His head snapped to the east. His ears twitched, pivoting slightly toward the noise. 

BOOM. BOOM. CRASH.

It wasn't construction. The cadence was too erratic. It sounded like explosions. It sounded like...

Burnt sugar. 

A sudden gust of wind carried the distinct, acrid scent of nitroglycerin to his nose. Izuku’s pupils contracted, narrowing into reptilian slits for a fraction of a second before expanding back to normal. His predatory instincts flared, flooding his system with adrenaline. 

Kacchan.

Without a conscious thought, Izuku’s body moved. 

He didn't run like a normal person. He crouched slightly, allowing the high-set ankles of his digitigrade legs to coil like steel springs, and pushed off. The pavement beneath his feet cracked from the sheer force of the launch. 

Izuku vaulted over a twelve-foot chain-link fence in a single bound, his tail snapping downward to stabilize his flight. He landed silently on the roof of a parked delivery van, the suspension groaning heavily under his weight. He didn't stop. He bounded from the van to an awning, and from the awning to a streetlight, ricocheting through the narrow alleyways of Tatooin Shopping District like a green-and-black pinball. 

His kinetic vision processed everything in extreme slow motion. He tracked the smoke rising in the distance, calculating the wind trajectory, adjusting his bounds to avoid low-hanging power lines. 

He arrived at the scene in less than forty seconds.

Landing in a crouch on top of a bus shelter just outside the main plaza, Izuku looked down at the chaos. A crowd had formed, held back by a few local pro heroes. Fires were raging in the streets, storefronts shattered, and an overturned car was burning near the center.

In the middle of the devastation was a creature out of a nightmare. It was a massive, undulating mass of dark green sludge, fluid and amorphous, save for two large, yellow eyes and a mouth full of jagged, grotesque teeth. 

And trapped within the center of the viscous fluid, struggling violently and gasping for air, was Katsuki Bakugo.

"His Quirk is too volatile! We can't get close!" Death Arms, a hero with immense physical strength, shouted over the roar of the flames, shielding his face. 

"My wood will catch fire!" Kamui Woods yelled in frustration. "And Mt. Lady can't fit down this two-lane street without crushing the civilians!"

The pros were standing by. They were waiting for someone with a suitable Quirk. 

Izuku’s mind raced, his hyper-analytical brain running through hundreds of scenarios a second. 

The villain is composed entirely of liquid. Blunt force attacks from Death Arms are useless; they just splash and reform. Kamui Woods is weak to Bakugo's explosions. Backdraft is busy putting out the fires.

Izuku stared at Bakugo. The explosive boy's eyes were bloodshot, tears streaming down his face as the sludge forced its way down his throat. He was suffocating. He was dying.

Kacchan's explosions are happening inside the sludge, but the lack of oxygen is making them weaker. The villain's eyes and mouth are the only solid components. The rest is non-Newtonian fluid.

"Wait until a hero with an elemental Quirk arrives!" a police officer yelled into a megaphone.

Wait? Izuku's tail lashed violently against the roof of the bus shelter, denting the metal. If we wait, he dies.

The predatory instinct that Izuku spent every waking moment suppressing suddenly roared to life in the back of his mind. But this time, he didn't fight it. He embraced it. He harnessed the feral, killing intent of the apex predator and directed it entirely at the sludge.

The transition from a quiet, calculating middle schooler to a prehistoric weapon was instantaneous. 

Izuku dropped into a deep crouch. The muscles in his digitigrade calves tightened until they looked like bundled steel cables beneath his skin. 

He took a deep breath. 

Clack.

With a sound like a switchblade deploying, the eight-inch sickle claws on Izuku’s inner toes snapped down from their elevated resting position. They locked into place parallel to the ground, gleaming with a deadly, bone-white sharpness. 

Izuku didn't yell. Predators don't scream before they strike. 

He vanished.

BOOM!

The roof of the bus shelter caved in completely, the glass shattering outward in a shockwave as Izuku launched himself horizontally over the heads of the crowd. 

Death Arms only saw a green blur streak past his shoulder. "Hey! Kid, get back here!"

Izuku was airborne, flying straight into the inferno. He didn't aim for the villain. He aimed for a reinforced concrete light pole to the left of the monster. He hit the pole feet first, his claws sinking deep into the concrete to anchor him for a microsecond. 

The Sludge Villain looked up, its massive yellow eyes widening in shock. "What the hell is—"

Izuku used his tail to violently pivot his entire body 180 degrees while horizontally attached to the pole. All of his kinetic energy, combined with the extreme torque of his twist, was funneled into his legs. 

He initiated his ultimate, highly-theoretical, never-before-tested maneuver.

Razor Talon Leap Strike.

Izuku kicked off the pole. The concrete pillar snapped in half from the recoil. 

He shot toward the Sludge Villain like a ballistic missile. Because the villain was made of liquid, a physical strike would just get Izuku stuck. But Izuku wasn't trying to kick the sludge. He was aiming for the air around it.

As he flew forward, Izuku executed a rapid, blindingly fast scissor-kick. His molecularly sharp sickle claws slashed through the air at supersonic speeds. The sheer velocity and the razor-thin edge of the keratin scythes didn't just cut the air; they displaced it, creating a localized vacuum—a phenomenon known as kamaitachi, or a sickle-weasel wind shear. 

Two massive, crescent-shaped blades of highly compressed, razor-sharp wind erupted from Izuku’s feet. 

The wind-blades ripped through the center of the Sludge Villain. The liquid body, incapable of stopping a pressure vacuum, was parted like the Red Sea. But more devastatingly, the wind shear struck the only solid things in its path: the villain's eyes and teeth.

"AGGGGGGGGHHHHH!" 

The Sludge Villain shrieked in absolute agony as the wind-blades severely lacerated its massive yellow eyeballs and shattered its jagged teeth into dust. The pain and the sudden displacement of its liquid form caused the villain's grip to fail instantly.

The sludge exploded outward in a massive splatter, losing all cohesion. 

Bakugo was thrown free, coughing violently, covered in viscous green slime. 

Izuku’s momentum carried him completely through the gap he had created in the villain. He soared over Bakugo, somersaulted twice in mid-air, and landed flawlessly on the asphalt in a three-point superhero stance. His tail whipped out, absorbing the final traces of his kinetic energy. The asphalt beneath his claws cracked into a spiderweb pattern.

With a swift, practiced motion, Izuku stood up, his claws immediately retracting upward with a clack to keep from ruining the road further. He looked back at the villain. 

The sludge was writhing on the ground, frantically trying to pull itself back together, crying out in pain from its slashed eyes. But before it could reform, the sky darkened.

A massive figure landed in the center of the plaza, dropping from the heavens like a meteor. The shockwave of his arrival blew out the remaining fires. 

"I AM PATHETIC," a voice boomed, deeper and more powerful than thunder. 

Izuku’s eyes widened. Standing before him, clad in a white t-shirt and cargo pants, coughing up a small amount of blood but radiating absolute power, was the Number One Hero. 

All Might.

"I TOLD A YOUNG FAN EARLIER THAT PROS ARE ALWAYS RISKING THEIR LIVES," All Might bellowed, his massive fists clenching as he glared down at the shuddering sludge villain. "YET I HESITATED! I LET A CHILD DO MY JOB!"

All Might pulled his arm back. The sheer muscle mass of his bicep seemed to warp the air around it. 

"TEXAS... SMASH!"

All Might threw a right hook. He didn't hit the villain. He hit the air. The resulting wind pressure was so astronomically immense that it created a localized tornado. The Sludge Villain was instantly ripped into thousands of microscopic droplets, scattering across the plaza. The clouds above the city literally parted, allowing the golden afternoon sun to pour down into the ruined street.

Silence fell over the plaza, save for the patter of sludge raining down on the pavement. 

Izuku stood frozen, staring in absolute awe at his lifelong idol. But as the crowd began to cheer, Izuku felt a heavy hand on his shoulder. He turned to see Death Arms glaring down at him, looking furious.

"Are you out of your damn mind, kid?!" the pro hero barked. "You could have been killed! Or worse, your Quirk could have killed the hostage! That was incredibly reckless!"

Kamui Woods walked over, crossing his arms. "He's right. You have a powerful Quirk, obviously a mutant strain, but jumping into a hostage situation without a license is illegal and foolish. You need to leave this to the professionals."

Izuku looked down at his clawed feet. He felt the familiar weight of society's judgment. He had saved a life, but all they saw was an uncontrollable, dangerous beast acting on instinct. 

"I... I'm sorry," Izuku bowed his head politely, his tail drooping low to the ground in submission. "My body just moved on its own. I won't do it again."

Nearby, the paramedics were checking on Bakugo. The explosive blonde pushed them away, his crimson eyes locking onto Izuku. He marched over, ignoring the pros. 

"Deku," Bakugo growled, his voice hoarse from the sludge. 

Izuku looked up. 

Bakugo didn't yell. He didn't ignite his palms. He just stared intensely at the boy who had just cleaved a liquid monster in half with sheer air pressure. "I didn't ask for your help. I had it under control. Don't you ever look down on me again, you damn dinosaur." 

Bakugo turned and walked away, his pride bruised but his life intact. Izuku knew it was the closest thing to a "thank you" Bakugo would ever give.

After giving a brief statement to the police—who mostly just gave him a stern warning about vigilantism—Izuku began the long walk home. The adrenaline had faded, leaving behind a deep, exhausting ache in his calves.

The sun was setting, casting the city in hues of purple and orange. Izuku walked with a heavy heart. Even when I save someone, I get yelled at, he thought, his tail swishing lazily behind him. My Quirk is just too dangerous. Maybe they're right. Maybe I can't be a hero like All Might. Maybe I'm just built to be a predator.

"I AM HERE!"

Izuku yelped, leaping backward a solid ten feet and instinctively dropping into a defensive crouch as All Might suddenly slid out from a nearby alleyway, striking his signature pose. 

"All Might?!" Izuku gasped, his eyes wide. "What are you doing here? How did you get away from the reporters?"

"HAHAHA! STANDING FOR INTERVIEWS IS A BREEZE FOR THE SYMBOL OF—HRK!"

Suddenly, All Might deflated. The massive, towering titan of muscle vanished in a puff of steam, replaced by a skeletal, emaciated man in a baggy white t-shirt. He coughed violently, wiping a trail of blood from his chin.

Izuku screamed, his tail sticking straight up in terror. "Ahhh! You deflated! Are you an imposter?! A fake?!"

"I assure you, I am All Might," the skeletal man sighed, sitting down heavily against the brick wall of the alley. He lifted his shirt, revealing a horrific, purple-and-red scar that looked like an entire chunk of his ribcage was missing. "I suffered this injury five years ago in a fight against a villain. It destroyed my respiratory system and a good chunk of my stomach. I can only do hero work for about three hours a day now."

Izuku stared in horror, his analytical brain immediately cross-referencing every major fight from five years ago. "Toxic Chainsaw?"

"No, that punk couldn't scratch me," All Might said, waving a bony hand. "This fight was kept under wraps. But I'm not here to talk about my failing health, young man. I came here to talk about you."

Izuku blinked. "Me?"

All Might’s sunken blue eyes locked onto Izuku. The goofy, larger-than-life persona was completely gone, replaced by a deadly serious, penetrating gaze. 

"Those pros back there chewed you out because it's their job to enforce the law," All Might said, his voice quiet but echoing in the alleyway. "But I saw what you did. I saw it from the crowd before my time limit allowed me to act."

Izuku looked away in shame. "I know. It was reckless. My Quirk... it's a mutation. It's called Apex Deinonychus. I'm essentially built like a predatory dinosaur. When I saw Kacchan—my classmate—dying, my instincts just took over. I couldn't stop myself. I used a lethal technique."

"Lethal?" All Might raised a skeletal eyebrow. "Young man, what you did wasn't just raw power. It was surgical."

Izuku’s head snapped up in surprise. 

"I've been in the hero business a long time," All Might continued, leaning forward. "I know the difference between a wild beast lashing out and a warrior who knows exactly what he is doing. The wind pressure you created with those claws of yours... you perfectly calibrated the angle and the force. You sliced the villain's eyes enough to cause excruciating pain and break his grip, but you didn't sever his ocular nerves. You pulverized his teeth, but you didn't touch your friend."

All Might stood up, walking slowly toward Izuku. "You possess a Quirk that is, by its very nature, built for slaughter. Society looks at claws like that and sees a villain. But today, when everyone else hesitated—including me—a boy with the body of a monster threw himself into the fire to save a life, demonstrating absolute, masterful restraint."

Tears began to well up in Izuku's eyes. For ten years, he had fought his own body. He had hated his claws. He had feared his own strength. 

"Your Quirk is terrifying," All Might said softly. "It is lethal. And if you lose control, you could kill someone. But a hero isn't defined by the tool they use. A hero is defined by the heart that guides it. You have a predator's body, but you have a true hero's heart."

Izuku broke down. He dropped to his knees, his hands covering his face as he sobbed loudly. The immense weight of a decade of fear, isolation, and suppression came pouring out in a flood of tears. His tail wrapped around his own leg as he cried, finally hearing the words he had desperately needed to hear his entire life.

All Might waited patiently for the boy to compose himself. When Izuku finally wiped his eyes and looked up, the Symbol of Peace smiled warmly.

"I am currently looking for a successor, young man," All Might said. "Someone to pass the torch to. I was considering offering you a power that has been passed down for generations."

Izuku blinked, confused. "A power? But Quirks can't be transferred..."

"This one can," All Might said mysteriously. "However... watching you today, I realized something. You don't need it."

Izuku tilted his head, his ears perking up. "I don't?"

"No," All Might chuckled. "Your body is already an unparalleled kinetic engine. If I gave you my power on top of your own terrifying physical strength, you might literally kick the moon out of orbit. No, you have all the raw power you will ever need to reach the top. What you need is not more power."

All Might extended a bony, calloused hand toward the kneeling boy.

"What you need, young man, is a master," All Might declared. "Someone to teach you how to temper that lethal edge. How to turn a weapon of slaughter into an unbreakable shield for the innocent. If you are willing, I will take you on as my personal pupil. I will teach you the art of absolute control, and together, we will prepare you to conquer U.A. High."

Izuku stared at the extended hand. His heart pounded in his chest, a wild, rhythmic drumbeat that resonated with every fiber of his being. The greatest hero in the world wasn't offering him a shortcut. He was offering him guidance. He was offering to help him tame the beast within.

Izuku Midoriya stood up on his digitigrade legs. He looked at All Might, his green eyes burning with a fierce, unwavering determination that made the Symbol of Peace grin.

Izuku reached out and grasped All Might's hand. 

"Yes, sir," Izuku said, his voice steady and resolute. "I accept."

The sun finally dipped below the horizon, casting the alley in shadow. But for the first time in his life, Izuku Midoriya was no longer afraid of the dark. The predator had finally found its purpose. The hunt for U.A. had officially begun.

The dawn wind blowing off the coast of Musutafu was bitter and laden with the scent of salt, rust, and rotting kelp. Dagobah Municipal Beach Park had once been a picturesque coastline, a place where families gathered to watch the sunset. Over the years, the ocean currents and illegal dumping had transformed it into a sprawling, mountainous labyrinth of metallic refuse, discarded appliances, and industrial waste. 

It was a graveyard for the obsolete. And for the next ten months, it was Izuku Midoriya’s dojo.

"THIS IS YOUR NEW PROVING GROUND, YOUNG MIDORIYA!" 

All Might’s booming voice echoed across the dunes of trash. The Number One Hero stood atop a rusted, overturned refrigerator, fully buffed up into his colossal muscle form, his golden hair catching the early morning light. "HEROES TODAY ARE TOO RELIANT ON FLASHY QUIRKS! THEY FORGET THAT THE FOUNDATION OF ANY GREAT POWER IS THE VESSEL THAT HOLDS IT!"

Izuku stood at the base of the trash mountain, his digitigrade legs shifting slightly in the sand. He wore a simple white tank top and custom-tailored athletic shorts that flared above his knees, allowing his massive, backward-jointed calves and heavily scaled feet full freedom of movement. His tail swished rhythmically behind him, carving smooth, crescent arcs into the wet sand. 

"I understand," Izuku called back, looking up at the towering piles of junk. "But... how exactly does moving trash help me control my Quirk? My power isn't exactly suited for heavy lifting. My upper body is just standard human."

All Might deflated with a sudden hiss of steam, dropping down to the sand in his skeletal form. He wiped a drop of blood from his chin and smiled, a sharp, calculating gleam in his sunken blue eyes. 

"Ah, but that is exactly the point," All Might said, pulling a small, battered notebook from his pocket. It wasn't one of Izuku's; it was All Might's own lesson plan. "Your Quirk, Apex Deinonychus, is a masterpiece of kinetic potential. Your lower body generates terrifying amounts of torque, velocity, and shear force. But a cannon is useless if it's mounted on a frail carriage. The recoil will tear it apart."

All Might pointed a bony finger at Izuku's chest. "You've spent your entire life suppressing your predatory instincts, trying not to hurt anyone. In doing so, you've artificially limited your own kinetic ceiling. We are not just going to build your upper body to handle the G-forces your legs produce; we are going to train your mind to wield your legs like a master swordsman wields a blade."

He gestured to the sprawling sea of trash. "I want you to clear this beach. But you aren't going to just carry this junk. You are going to kick it."

Izuku blinked. "Kick it?"

"Yes," All Might nodded. "But here is the catch. You must move the trash without cutting it. No sickle claws. You must rely entirely on the blunt force of your heels, calibrating your power perfectly to launch the debris into my pickup truck without piercing the metal, shattering the plastic, or tearing the rubber."

Izuku stared at a nearby rusted washing machine. He looked down at his feet. The massive, eight-inch keratin scythes rested securely on their elevated joints on his inner toes. He took a deep breath, focusing on the complex network of muscles, tendons, and ligaments in his legs. 

"Right," Izuku muttered, his eyes narrowing, his pupils contracting slightly into predatory slits. "Blunt force only. Velocity control. Angle of impact."

Izuku approached the washing machine. He closed his eyes, visualizing the strike. The human brain naturally calculates trajectories, but Izuku’s mutated predatory cerebellum processed physics at an entirely different speed. He didn't just see the washing machine; he saw its center of mass, the weak points in the rusted chassis, and the exact vector required to launch it thirty yards. 

He lunged.

Izuku moved as a blur. He pivoted on his left foot, spinning his body like a top, using his thick, muscular tail to counterbalance the extreme torque. His right leg whipped around in a devastating roundhouse kick. He kept his sickle claw locked pointing upward, ensuring the incredibly dense bone of his heel made contact.

CLANG!

The impact sounded like a church bell ringing in a tempest. The washing machine caved in slightly under the sheer concussive force, lifting off the sand. It soared through the air in a perfect, high arc, sailing over a pile of tires—

And crashed straight through the windshield of All Might’s pickup truck, obliterating the glass and embedding itself in the dashboard.

Silence descended upon the beach, save for the sound of crashing waves and the hiss of the truck’s dying radiator. 

Izuku’s tail dropped, wrapping around his right leg in an instinctual display of extreme guilt. "Oh my god. All Might, I am so sorry! I miscalculated the kinetic transfer—the rust compromised the structural integrity, changing the weight—"

"HAHAHA!" All Might suddenly coughed, spitting up a bit of blood but laughing heartily. "It's fine, my boy! A small price to pay for progress! Your power is astonishing. But you see the problem? Your legs are like coiled springs. You used too much force and angled your hip a fraction of a degree too high. Control is a conscious, active discipline."

For the next ten months, Dagobah Beach became Izuku’s crucible. 

The training was absolute hell. Izuku’s body was pushed to the breaking point daily. He hauled refrigerators by tying ropes to his waist and sprinting through the deep sand, forcing his digitigrade legs to dig deep for traction. He practiced leaping between unstable towers of junk, learning to use his tail to violently redirect his momentum mid-air. 

But the hardest part was the striking. 

Week by week, Izuku painstakingly learned to compartmentalize his instincts. He visualized a mental switch in his head. 

Switch Off: The hero. The blunt instrument. The sheathed claws and the heel strikes meant to subdue, push, and break without severing. 

Switch On: The apex predator. The sickle-claws deployed. The razor-talon leap strikes meant to cleanly bisect, eviscerate, and destroy.

By month six, Izuku could bounce a microwave off three different junk piles like a pinball using only rapid-fire heel kicks. 

By month eight, All Might introduced the 'egg test.' Izuku had to execute a full-speed leap strike against a watermelon resting on a wooden post. If his claws were even a millimeter too loose, the vacuum shear would split the melon. If he used too much blunt force, the melon would explode. He had to strike it just hard enough to knock it off the post completely intact. It took three weeks and fifty ruined watermelons before he could do it flawlessly ten times in a row.

On the morning of the U.A. Entrance Exam, the sun rose over a pristine, completely empty Dagobah Beach. The sand gleamed like spun gold, the ocean waves gently lapping at a shoreline devoid of a single piece of trash. 

Standing at the edge of the pier was a boy who had undergone a total metamorphosis. 

Izuku Midoriya, at fifteen years old, had grown into his mutant anatomy perfectly. His upper body, once lean and unremarkable, was now corded with dense, swimmer-like muscle, built specifically to withstand the bone-shattering G-forces his legs could produce. His digitigrade legs were thicker, the scales a deeper, healthier forest green, and his tail moved with the fluid, calculated grace of a coiled viper. 

All Might stood behind him in his skeletal form, looking out at the clean beach, a profound sense of pride swelling in his hollow chest. 

"You did it, young Midoriya," All Might said softly. "You didn't just clean the beach. You mastered yourself."

Izuku looked down at his clawed feet. He flexed his toes, the massive eight-inch scythes sliding down with a sharp snikt, gleaming like polished ivory in the morning light, before instantly snapping back up into their locked, sheathed position. 

"I feel it, All Might," Izuku said, his voice calm, absent of the nervous stutter that used to plague him. "I can feel the exact edge of my power. I know exactly when to hold back. And today... I know exactly when to let it out."

All Might grinned. "Then go, my boy. Show them the hero you were born to be."

The gates of U.A. High School were colossal, towering arches of glass and steel that loomed over the incoming hordes of middle school students. The sheer size of the campus was intimidating, designed to make the aspiring heroes feel small, to test their resolve before they even stepped inside.

Izuku walked toward the main building, his tail swaying in a slow, relaxed rhythm. He wore a custom dark green tracksuit, heavily reinforced at the seams. He drew more than a few stares. Mutant Quirks weren't uncommon—there were students with horns, extra arms, and oddly colored skin—but there was something fundamentally different about Izuku. 

He didn't just look like an animal; he moved like one. There was no wasted motion in his stride. His heels never touched the ground. Every step was a perfectly balanced transfer of kinetic energy, silent and predatory. 

"Out of my way, Deku."

Izuku paused, turning his head slightly as Katsuki Bakugo stalked past him. The explosive blonde looked tense, his hands shoved deep into his pockets, his shoulders hunched. 

"Good morning, Kacchan," Izuku said politely. "Good luck today."

Bakugo stopped. He didn't look back, but his jaw clenched tight. Ten months ago, Bakugo would have sneered and thrown an insult. But over the last year, he had watched Izuku change. He had seen the terrifying, serene focus in Izuku's eyes during class. Bakugo wasn't stupid; his combat instincts were unmatched. He could tell, on a primal level, that the "dinosaur" behind him was no longer just a lethal anomaly. He was a weapon that had learned how to aim.

"Don't patronize me," Bakugo growled, marching forward. "I'm going to get the top score. Just stay out of my blast radius."

Izuku smiled softly and continued walking. 

Suddenly, a blur of motion caught the edge of his kinetic vision. A girl with a brown bob and permanent blush on her cheeks had tripped over a slightly uneven paving stone. Time seemed to slow down for Izuku as he calculated her trajectory, her mass, and the velocity of her fall. 

He didn't even need to shift his legs. As the girl tipped forward, bracing for a painful face-plant, Izuku’s long, muscular tail whipped out with surgical precision. 

The thick, scaled appendage wrapped gently but firmly around her waist, stopping her fall a mere two inches from the concrete. 

"Woah!" the girl yelped in surprise, finding herself suspended in mid-air. 

Izuku gently hoisted her back to her feet, his tail unwrapping and returning to its slow sway behind him. "Are you okay?" he asked, turning to face her. 

The girl blinked, looking from the pavement to Izuku, and then down to the massive green tail that had just caught her. Instead of looking frightened by his reptilian features, her face broke out into a massive, beaming smile. 

"Wow! That was amazing!" she gasped. "Your tail is so strong! And fast! I was going to use my Quirk to catch myself, but you beat me to it. Thanks!"

Izuku felt a sudden rush of heat to his cheeks. He had spent ten months fighting trash and talking to a skeletal old man; he was fundamentally unprepared for a cute girl praising his mutation. "O-Oh, it was nothing! Just, um, spatial awareness! I'm Izuku Midoriya."

"Ochaco Uraraka!" she beamed, adjusting her backpack. "Your Quirk is so cool. You look like a raptor! I bet you're super fast. Anyway, I'm super nervous, but let's both do our best, okay?"

She waved happily and jogged off toward the auditorium. Izuku stood there for a moment, his tail wagging slightly—a reflex he absolutely hated but couldn't completely suppress when he was happy. She wasn't scared at all, he thought, a newfound warmth spreading in his chest. I can do this.

The written exam was a grueling gauntlet of mathematics, heroic law, and physics, but Izuku’s obsessive studying habits paid off. He breezed through the packets, his mind already drifting to the practical application.

An hour later, the examinees were seated in a massive, darkened auditorium. Pro Hero Present Mic, the Voice Hero, stood illuminated on the stage, screaming into the microphone with enough decibels to rattle Izuku’s sensitive eardrums.

"WELCOME TO TODAY'S LIVE PERFORMANCE! EVERYBODY SAY HEYYYY!"

Dead silence. 

"TOUGH CROWD!" Present Mic laughed, unbothered. He clicked a button, and the massive screen behind him lit up with a schematic of a mock city. "AS IT SAYS IN THE APPLICATION, YOU'LL BE CONDUCTING TEN-MINUTE MOCK URBAN BATTLES AFTER THIS! YOU'LL BE SCATTERED ACROSS DIFFERENT BATTLE CENTERS!"

Present Mic explained the rules. Three types of robotic "Villains," worth one, two, and three points respectively. Destroy them, rack up points. It was a straightforward, brutal assessment of combat viability. 

Izuku stared at the schematics of the robots. Armored chassis. Sensor optics. No organic components. No hostages. No civilians.

For the first time in his life, Izuku realized something beautiful: I don't have to hold back. 

His sickle claws shifted nervously inside his reinforced shoes. He was going to be allowed to unleash the apex predator against targets that couldn't bleed. A low, barely audible trill of excitement rumbled in the back of his throat. 

"Excuse me! I have a question!" 

A tall, broad-shouldered boy with glasses and a rigidly serious posture stood up, pointing sharply at the stage. "On the printout, there are four types of villains! If this is a misprint, then U.A., the top hero academy in Japan, should be ashamed! Furthermore..." 

The bespectacled boy turned around, his gaze sweeping over the crowd until he locked onto Izuku, who was sitting two rows back, muttering rapid-fire calculations under his breath. 

"You, with the green tail!" the boy barked. "You've been muttering this entire time, and quite frankly, the constant movement of your tail is incredibly distracting! If you are not taking this seriously, then leave immediately!"

The entire auditorium turned to look at Izuku. 

Izuku stopped muttering. Slowly, he looked up. He didn't mean to do it. It wasn't an intentional act of malice. But being aggressively called out triggered a deeply ingrained instinct. For a fraction of a second, the human warmth vanished from Izuku’s emerald eyes. His pupils contracted into razor-thin, vertical slits. His jaw set, and a silent, overwhelming aura of predatory intent washed over the surrounding rows. 

The boy with glasses froze. The reprimand died in his throat. A primal, evolutionary chill ran down his spine, the kind of absolute terror an herbivore feels when a shadow passes over it in the tall grass. He swallowed hard, suddenly feeling entirely exposed. 

Izuku blinked, his pupils expanding back to normal, and he bowed his head apologetically. "I'm very sorry," Izuku said softly, pulling his tail flush against his chair. "I didn't mean to be a distraction. I'll be quiet."

The bespectacled boy slowly sat back down, his heart hammering against his ribs, unable to shake the feeling that he had just yelled at a loaded gun. 

Present Mic awkwardly cleared his throat. "RIGHT! WELL! EXAMINEE 7111, THANKS FOR THE GREAT MESSAGES! THE FOURTH VILLAIN IS THE ZERO POINTER! IT'S AN OBSTACLE! JUST AVOID IT, LISTENERS!"

Battle Center B was a sprawling, hyper-realistic replica of a dense urban district. Towering skyscrapers, winding alleyways, and broad intersections created a perfect arena for three-dimensional maneuvering. 

Hundreds of examinees stood behind the massive steel starting gates. The tension was palpable. Some were stretching, others were psyching themselves up. Izuku stood near the front of the pack, his eyes locked on the heavy metal doors. 

He didn't stretch. He didn't need to. His blood was singing. 

He unstrapped the heavy covers over the toes of his custom athletic shoes, leaving his scaly, clawed digits completely exposed to the open air. He shifted his weight forward, balancing entirely on the balls of his digitigrade feet. His tail stuck straight backward, rigid as an iron bar. 

"Right, let's start!" Present Mic’s voice blared over the loudspeakers. "WHAT'S THE MATTER? THERE ARE NO COUNTDOWNS IN REAL BATTLES! RUN! RUN! RUN!"

The crowd hesitated for a split second, confused by the lack of a formal buzzer. 

Izuku did not hesitate. 

Clack. 

The massive sickle claws on his inner toes snapped down, locking into a parallel, horizontal alignment with the asphalt. 

He crouched, the densely coiled muscle fibers in his calves compressing to their absolute limit. 

BOOM.

The sound of the launch was deafening. The asphalt beneath Izuku’s feet exploded into a shower of gravel and dust as he unleashed the kinetic energy he had built up over ten months of grueling training. 

He didn't just run. He bounded. 

In a single, terrifyingly explosive leap, Izuku cleared a staggering fifty meters. He soared over the heads of the crowd, crossing the threshold of the gates before anyone else had even taken their third step. 

High up in the observation room of U.A., a wall of monitors displayed the action from every conceivable angle. A dozen pro heroes sat in the darkness, watching the incoming class.

"Good grief," Shota Aizawa muttered from beneath his capture scarf, his tired eyes widening slightly as camera 4 struggled to track a green blur. "Did someone fire a missile in Battle Center B?"

"Examinee 7112. Izuku Midoriya," Principal Nedzu chimed in, taking a calm sip of his tea. "Quirk: Apex Deinonychus. A mutant-type hybrid. His file indicates extreme lower-body strength, but this velocity... this is extraordinary."

Back in the Battle Center, Izuku touched down halfway down the main street. He hit the ground running, his loping, digitigrade strides eating up the pavement at forty miles per hour. 

Three robotic villains—two 1-Pointers and a 2-Pointer—rolled out from an intersection, their red optic sensors locking onto him. 

"Target acquired," the metallic voice droned.

Izuku’s lips curled into a fierce, exhilarated smile. He didn't break stride. He accelerated. 

As the 2-Pointer raised its laser cannons, Izuku executed a violent vault, leaping off the hood of a parked mock-car. He soared ten feet into the air, flying straight at the machine. 

He initiated the Razor Talon Leap Strike. 

At the apex of his jump, Izuku scissored his legs with blinding speed. The eight-inch keratin scythes carved through the air. The resulting kamaitachi wind-blade erupted outward, a crescent of localized vacuum pressure. 

The wind-blade struck the 2-Pointer first, shearing cleanly through its sensor array and blinding it. But Izuku wasn't done. Gravity brought him down directly on top of the machine. 

He didn't use blunt force. He let the sickle claws do the work. 

With a sickening screech of tearing metal, Izuku’s right claw sank deep into the robot's armored chassis, piercing the reinforced steel as if it were wet cardboard. Utilizing his tail for leverage, Izuku ripped his leg sideways in a brutal, eviscerating arc. 

The 2-Pointer was cleanly bisected, its upper half sliding off its treads and crashing to the street in a shower of sparks and hydraulic fluid. 

Izuku didn't stop to admire his work. Using the falling chassis as a springboard, he kicked off the ruined robot, ricocheting toward the two 1-Pointers. He moved like a pinball of destruction. He landed on the wall of a nearby building, his claws gripping the brickwork for a fraction of a second before he launched himself horizontally. 

He spun mid-air, a horizontal cyclone of green scales and razor-sharp bone. He passed between the two 1-Pointers. The vacuum wind generated by his spinning claws sliced through the vulnerable neck joints of both machines simultaneously. Two robotic heads hit the asphalt. 

Four points, Izuku calculated, landing gracefully on a streetlight. Thirty seconds elapsed.

The beast was loose. 

For the next five minutes, Battle Center B became Izuku Midoriya’s personal hunting ground. He abandoned the streets entirely, taking to the verticality of the mock city. He bounded from wall to wall, alley to alley, utilizing the sheer aerodynamic perfection of his tail to change direction mid-air. 

He was untouchable. The robots' targeting algorithms couldn't process his erratic, hyper-kinetic movements. By the time a 3-Pointer aimed a missile at him, Izuku was already behind it, delivering a downward Talon Strike that caved in its exhaust port and severed its internal wiring. 

"Twenty-eight... thirty-four... forty-two..." Izuku muttered, his breath coming in steady, rhythmic pulls. He was covered in engine grease, but he wasn't even sweating. The beach training had given him the stamina of a marathon runner. 

He spotted a cluster of five 3-Pointers cornering a group of examinees—including the bespectacled boy who had yelled at him earlier. The boy, using engine pipes on his calves, kicked one robot away but was quickly overwhelmed by the sheer numbers. 

"Look out!" a student screamed as a 3-Pointer raised a massive pincer. 

FWOOOSH.

A massive blade of compressed wind tore down from the sky, cleanly slicing the 3-Pointer’s pincer arm off at the elbow. 

The examinees looked up in awe. 

Izuku was free-falling from the roof of a six-story building. He fell directly into the center of the robotic cluster. Just before he hit the ground, he slammed his tail against a lamppost, abruptly arresting his downward momentum and converting it into rotational energy. 

He became a blender of razor-sharp claws. He struck the first robot in the chest, tearing out its power core. He bounced off its collapsing frame, drove his left claw through the optic sensor of the second, and used a vicious, blunt-heel roundhouse to shatter the chassis of the third. 

In less than four seconds, millions of yen worth of U.A. hardware was reduced to smoking, dismembered scrap. 

Izuku landed silently amidst the wreckage. His breathing was calm. His massive sickle claws dripped with hydraulic fluid, the tips gleaming lethally in the sun. He looked over his shoulder at the paralyzed examinees, his slit pupils narrowing. 

"You should keep moving," Izuku said, his voice quiet but carrying a chilling, authoritative resonance. "There are more coming from the east."

He crouched, the concrete cracking under his talons, and launched himself back into the sky, disappearing over the rooftops in a single, fifty-meter bound. 

The bespectacled boy stared at the ruined robots, his jaw hanging slack. "What... what manner of Quirk is that? He didn't just break them. He dismantled them."

In the observation room, the pro heroes were dead silent. 

"Seventy-four points," the heroine Midnight whispered, her eyes wide. "He's accumulated seventy-four points in six minutes. He's entirely bypassed the structural defenses of the villains by targeting joints and using vacuum-shear mechanics. He's a monster."

"He's not a monster. He's a surgical instrument," Aizawa corrected, leaning closer to the monitor. He noticed something the others missed. "Watch his strikes. His claws are devastating, yes. But look at his trajectory. He hasn't caused a single piece of shrapnel to fly toward another examinee. He isn't acting on wild instinct; he's exercising absolute, terrifying control over a hyper-lethal Quirk."

All Might, standing in the back of the room in his muscle form, grinned proudly, crossing his massive arms. Show them, my boy. Show them the fruits of your labor!

"Well, it's clear we have a prodigy," Nedzu said, interlacing his paws. "But a hero isn't just about destroying enemies. Let's see how our young predator reacts... when the ecosystem is disrupted."

Nedzu pressed a large red button on his console. 

RUMBLE.

Izuku, perched on top of a water tower, froze. His ears swiveled backward. The ground beneath the mock city was shaking. It wasn't a localized tremor; it felt like an earthquake. 

Windows in the nearby buildings shattered as a deafening, mechanical roar echoed through the streets. Dust plumed into the sky, blotting out the sun. 

At the end of the main avenue, the buildings themselves were pushed aside like cardboard boxes. 

The Zero Pointer emerged. 

Izuku’s eyes widened. It wasn't a robot. It was a walking skyscraper. It stood easily over a hundred feet tall, a colossal, heavily armored leviathan with treads the size of city blocks and massive, crushing arms that tore through the mock city infrastructure with horrifying ease. 

"LESS THAN TWO MINUTES REMAINING!" Present Mic announced. 

Panic erupted in the streets below. Examinees, realizing the sheer impossibility of fighting the behemoth, turned and fled. 

"Run!" 

"It's the Zero Pointer! Just get away from it!"

Izuku watched from the water tower. His analytical brain immediately registered the threat level. The armor is too thick for a standard wind-shear. The mass is too great for a blunt-force strike. The optimal strategy is evasion.

He turned to leap away toward a different block to hunt more 2-Pointers. But as he shifted his weight, his highly tuned ears picked up a sound amidst the chaos. 

A sharp, terrified cry of pain. 

Izuku looked back. Down on the avenue, directly in the path of the colossal robot’s encroaching treads, a girl was trapped. A massive chunk of debris from a shattered building had pinned her leg to the ground. 

It was the girl from the entrance. Uraraka.

The other examinees were running right past her, consumed by the panic of the ticking clock and the massive machine. The Zero Pointer raised its massive foot, casting a terrifying shadow over the trapped girl. 

Izuku didn't think. The calculations, the points, the exam—they all vanished from his mind. 

The mental switch in his head flipped. 

Clack.

The sickle claws locked down. His tail snapped rigid. The primal roar of the apex predator merged perfectly with the soul of a hero. 

Izuku didn't run away. He plummeted straight down from the water tower, hitting the asphalt in a dead sprint toward the towering behemoth. 

"What is he doing?!" one of the fleeing examinees screamed. 

Izuku didn't hear them. He was moving faster than he ever had in his life. The world blurred into a tunnel of colors. He reached the avenue, closing the distance to the Zero Pointer in seconds. But he couldn't just slash the tread; the machine's sheer weight would still crush Uraraka as it fell. 

He had to stop it from the top down. He had to sever the central nervous system. 

Izuku veered sharply to the right, running directly up the side of a partially collapsed skyscraper next to the Zero Pointer. His claws dug deep into the glass and steel, defying gravity. He sprinted vertically up the building, his powerful legs propelling him higher and higher. 

He reached the roof, five stories above the Zero Pointer's colossal head. 

Izuku vaulted off the edge of the building, launching himself into the open sky above the machine. Time froze. The massive robot slowly looked up, its singular, glowing red optic eye locking onto the tiny green speck in the air. 

High above the mock city, Izuku Midoriya drew his right leg back. The muscles in his thigh and calf contracted so violently they threatened to snap his own bones. He channeled every ounce of kinetic energy, every grueling hour of pulling refrigerators through the sand, every shattered watermelon, into a single, localized point of absolute destruction.

He threw his weight forward, whipping his tail down to accelerate his descent. He aimed both of his sickle claws straight downward, parallel to each other. 

"Meteoric Talon Leap Strike!"

Izuku hit the top of the Zero Pointer’s heavily armored skull. 

The impact did not create a localized cut. It created a catastrophic kinetic shockwave. Izuku’s hyper-dense, molecularly sharp sickle claws pierced the thick, blast-proof plating of the skull instantly. But the sheer velocity of his descent and the raw, unadulterated strength of his legs carried him deeper. 

Izuku drove his legs straight down. 

SKRRRRRRAAAAK!

A horrific, deafening screech of tearing metal echoed across the entire Battle Center. Izuku quite literally rode his momentum down through the center of the machine. The vacuum shear generated by his claws, combined with the extreme wedge-shape of his downward strike, forcibly parted the metal. 

Like an axe splitting a log, Izuku clove through the Zero Pointer’s head, severing its central processor, its optic array, and its primary hydraulic line in a single, devastating plunge. 

He burst out through the back of the robot’s neck in an explosion of sparks and shattered armor, landing gracefully on his feet amidst the falling debris. 

Behind him, the colossus froze. A massive, glowing fissure ran straight down the center of its head. The red optic light flickered, sparked, and died. 

With a slow, groaning shudder, the Zero Pointer collapsed backward, crashing into the ruined buildings behind it and sending a massive cloud of dust into the atmosphere. It was utterly, totally neutralized. 

The entire Battle Center went dead silent. The examinees who had been fleeing stopped and stared in open-mouthed, uncomprehending shock. 

Izuku didn't look at the explosion. He instantly dashed through the settling dust, arriving at Uraraka’s side. 

"Are you okay?" he asked, his voice returning to its soft, polite tone. He quickly used the blunt heel of his leg to kick the debris pinning her, shattering the concrete without touching her leg. 

Uraraka stared up at him, her eyes wide with a mixture of awe and relief. "Y-You saved me. You just... you destroyed that thing."

"TIME'S UP!" Present Mic’s voice blared over the sirens. 

Izuku exhaled deeply. His sickle claws retracted upward with a soft click. His tail dropped, sweeping the dust off the asphalt in slow, exhausted arcs. The adrenaline faded, replaced by the profound, agonizing burn of lactic acid in his legs. 

He looked down at his trembling, scaled hands, and then up at the U.A. observation tower. 

I did it, All Might, he thought, a tired but genuine smile breaking across his face. I didn't hold back, but I didn't lose control. I used the beast to protect.

In the observation room, the silence was finally broken by a low, impressed whistle from the Pro Hero Snipe. 

"Well," Aizawa said, a rare, terrifying grin pulling at the corner of his lips. "It looks like this year's class just found its apex predator."

The alarm clock on Izuku Midoriya’s desk didn’t even get the chance to ring. 

At exactly 4:59 AM, one minute before the alarm was set to go off, Izuku’s emerald eyes snapped open in the dark. The predatory brain he inherited from his Quirk did not do "groggy." It transitioned from deep, restorative sleep to high-alert wakefulness in a fraction of a millisecond. 

He sat up in bed, the sheets falling away from his heavily corded torso. He stretched, a low, rumbling yawn escaping his lips as his vertebrae popped in sequence. Behind him, his thick, scaly tail slipped out from under the blankets, swaying lazily in the cool morning air. 

Today was the day. His first day at U.A. High School. 

Getting dressed took slightly longer than it did for a normal student. The standard U.A. uniform was pristine, but Izuku had to send his measurements in weeks in advance to the support department for heavy modifications. The gray slacks had been completely overhauled. From the knee down, they flared out wide, accommodating the massive, backward-bending joints of his digitigrade legs. A specially reinforced, button-up slit at the base of the spine allowed his four-foot tail to pass through without tearing the fabric. 

He slipped into his custom footwear—heavy-duty, open-toed sandals made of a synthetic carbon-weave. They strapped securely over his scaled instep, leaving his toes and, more importantly, his deadly sickle claws completely exposed and unhindered. 

Izuku looked at himself in the mirror. He tightened his red tie. He took a deep breath, consciously relaxing the muscles in his jaw, softening his gaze, and forcing the razor-thin slits of his pupils to dilate into large, friendly circles. 

I am a hero, he reminded himself, a daily mantra. I protect. I do not hunt.

The commute to school was a delicate exercise in restraint. The morning rush hour in Musutafu was chaotic, filled with the sounds of blaring horns, shouting commuters, and flashing lights. To Izuku’s hyper-sensitive kinetic vision and acute hearing, it was a sensory overload. Every sudden movement in the crowd made his leg muscles twitch with the instinct to pounce or evade. He kept his hands in his pockets, his tail wrapped securely around his own waist under his blazer to keep it from accidentally swiping a passerby, and bounded softly along the pavement, his heels never touching the ground.

When he finally arrived at the towering door of Class 1-A, he paused. The door was massive, designed to accommodate students of all sizes and mutant Quirks. 

He could hear the voices inside before he even touched the handle. 

"Take your feet off of that desk this instant!" a rigid, authoritative voice barked. 

"Huh?" another voice sneered—one that Izuku knew all too well. "What's your problem, four-eyes?"

"It is the first day of school, and you are already disrespecting the property of our great predecessors!" 

Izuku opened the door. The sight before him was exactly as he had predicted. Tenya Iida, the tall, bespectacled boy from the entrance exam, was chopping his arm through the air like a metronome, glaring down at Katsuki Bakugo. Bakugo, naturally, was leaning back in his chair, his feet propped up on the desk, an arrogant smirk plastered across his face.

"Disrespecting?" Bakugo scoffed. "Which crappy middle school did you crawl out of, extra?"

"I attended Somei Private Academy! My name is Tenya Iida!"

"Somei, huh? So you're a stuck-up elite," Bakugo chuckled, small sparks of nitroglycerin popping off his fingertips. "I'm going to have fun crushing you."

"Crushing me?! You truly intend to be a hero with that attitude?" Iida gasped. 

Iida turned his head, catching sight of Izuku standing in the doorway. The tall boy’s eyes went wide, recognizing the green-haired student instantly. He abandoned Bakugo and marched straight toward Izuku, his posture stiff.

"You!" Iida announced, his voice echoing in the suddenly quiet classroom. "You are the one who deduced the true nature of the practical exam! The way you completely dismantled that Zero Pointer... it was a display of martial prowess unlike anything I have ever seen. I must apologize! I misjudged you in the auditorium. You are clearly superior to me!"

Izuku waved his hands frantically, feeling the heat rush to his cheeks. "N-No, I didn't deduce anything! I just... someone was in trouble, and I acted! It wasn't about points. I'm Izuku Midoriya. It's nice to meet you, Iida."

"Midoriya! Oh, thank goodness you're here!" 

Izuku’s tail gave an involuntary, happy wag as Ochaco Uraraka pushed past Iida, her face beaming. "I was hoping we'd be in the same class! That punch—or, well, kick—you did against the giant robot was amazing! You saved my life! I even went to Present Mic to try and give you some of my points, but he said you didn't need them!"

"Y-You tried to give me your points?" Izuku stammered, deeply touched. 

Before the conversation could continue, Bakugo kicked his desk. The loud crack drew everyone’s attention. Bakugo was glaring at Izuku, his crimson eyes burning with a mix of fury and intense rivalry. He had seen the broadcast of the exam scores. Midoriya hadn't just beaten him; he had annihilated his score. Bakugo had scored 77 combat points. Midoriya had scored 85 combat points and an unprecedented 60 rescue points. 

Bakugo opened his mouth to spit venom, but a gruff, exhausted voice cut through the tension.

"If you're just here to make friends, you can pack up your things and leave."

The entire class froze. Lying on the floor in the hallway, zipped up in a bright yellow sleeping bag like a giant caterpillar, was a haggard-looking man. He unzipped the bag and stood up, revealing messy black hair, a thick gray scarf, and eyes that looked like they hadn't seen sleep in a decade.

"It took you lot eight seconds to quiet down," the man sighed, pulling a juice pouch from his pocket and slurping it. "Time is limited. You kids are not rational enough. I am Shota Aizawa. I am your homeroom teacher."

The class gasped. A pro hero? As a homeroom teacher?

Aizawa reached into his sleeping bag and pulled out a blue-and-white U.A. gym uniform. "Put these on and head out to the training grounds. We're skipping orientation. We have work to do."

The sun beat down on the sprawling dirt field of the U.A. training grounds. Class 1-A stood in a loose cluster, dressed in their gym uniforms, looking nervously at Aizawa, who stood at the edge of a chalk-lined pitching circle. 

"A Quirk Apprehension Test?" the class echoed in unison.

"What about the entrance ceremony? Or guidance counseling?" Uraraka asked, clutching her hands to her chest.

"No hero has time for useless ceremonies," Aizawa replied flatly. "U.A. is known for its unrestricted traditions. That means teachers run their classes however they see fit. You've been taking standardized fitness tests since elementary school, but always with Quirks prohibited. It's irrational. The Ministry of Education is dragging its feet."

Aizawa pointed a finger at Bakugo. "Bakugo. You finished first in the practical exam. What was your farthest softball throw in middle school?"

"Sixty-seven meters," Bakugo replied confidently. 

"Try it with your Quirk," Aizawa said, tossing him a baseball. "Anything goes, just stay in the circle."

Bakugo stepped up to the plate. He rolled his shoulders, a vicious grin spreading across his face. He wound up, his arm pulling back. As he threw the ball, he ignited a massive explosion from his palm, launching the ball into the stratosphere with a deafening BOOM. 

"DIE!" Bakugo roared.

The ball vanished into the clouds. Aizawa held up a digital tracking device. It beeped. He turned the screen around to face the class. 

705.2 meters.

The class erupted into cheers and gasps.

"Seven hundred meters?! That's insane!"

"We get to use our Quirks as much as we want? This looks like fun!"

Aizawa’s eyes darkened. His capture scarf suddenly flared up around his neck, defying gravity. "Fun? You have three years here to become heroes. You think it's all going to be fun and games?" 

He glared at the students, a terrifying, oppressive aura washing over them. "Fine. Let's make this interesting. The student who ranks last in total points across all eight physical tests will be judged to have zero potential... and will be expelled."

Total silence fell over the field. 

Izuku didn't flinch. His green eyes narrowed slightly. He understood exactly what Aizawa was doing. It was a logical ruse designed to draw out their maximum potential. But even if it was real, Izuku had nothing to fear. He had trained his body in the most brutal conditions imaginable for ten months. He was ready.

"Test one: 50-meter dash," Aizawa announced, holding up a starting pistol.

The class lined up in pairs. Izuku watched closely as his classmates utilized their Quirks. Iida used his engine legs to rocket across the track in 3.04 seconds. Tsuyu Asui, a girl with a frog mutation, leaped across in 5.58 seconds. Bakugo used a series of rapid-fire explosions to propel himself across in 4.13 seconds. 

"Midoriya. Ojiro. You're up," Aizawa called. 

Izuku stepped up to the starting line. Mashirao Ojiro, a boy with a thick, muscular, primate-like tail, stepped up next to him. 

"Nice tail," Ojiro smiled politely, stretching his legs. "Mutant types have an edge in these physical tests, huh? Let's do our best."

"Thanks. You too," Izuku nodded. 

Izuku stepped to the line, but he didn't assume a runner's starting block pose. Instead, he dropped into a deep, predatory crouch. His digitigrade legs compressed. His torso leaned completely forward, parallel to the ground. His four-foot tail shot straight back, rigid as a steel beam to optimize aerodynamics. 

Aizawa narrowed his eyes, observing Izuku closely. A perfect biomechanical stance. He's minimizing wind resistance and maximizing the kinetic load on his calves. Let's see what the apex predator can do.

"On your marks," the robotic camera drone chirped. "Get set..."

BANG.

Ojiro pushed off the blocks, running with impressive speed. 

Izuku didn't run. He vanished. 

There was a deafening CRACK that sounded like a rifle shot as Izuku’s exposed, scaly toes dug into the dirt track. He cleared the 50-meter distance in a grand total of three massive, bounding strides. He moved so fast that the human eye could only register a dark green blur tearing across the field. He didn't disturb the air; he cleaved through it. 

He crossed the finish line and immediately whipped his tail around, digging his heels into the dirt to arrest his momentum, kicking up a massive cloud of dust. 

"1.12 seconds," the robotic voice announced. 

The class stared in stunned disbelief. 

"One point one two?!" Kaminari gasped, his jaw hitting the floor. "He broke the sound barrier! That's faster than Iida!"

Iida pushed his glasses up his nose, utterly astounded. "His legs... the inverted joint structure and the hyper-dense musculature operate like perfectly calibrated pistons. It's a marvel of physiological engineering!"

Aizawa looked at the stopwatch and scribbled on his clipboard. Unbelievable speed. He moved faster than my eyes could accurately track. If he had used those sickle claws of his on a villain at that velocity, he would have eviscerated them before they even registered his presence.

The tests continued. 

In the grip strength test, a multi-armed boy named Shoji scored an impressive 540 kilograms. Izuku gripped his machine. He scored an incredibly respectable, but completely human, 85 kilograms. 

"Aw, I thought you'd crush it!" Mina Ashido, a pink-skinned girl, said with a pout. 

Izuku chuckled, rubbing the back of his neck. "My Quirk is strictly localized to my lower body and tail. My arms are just... well, normal arms. I trained them a lot, but they're not superhuman."

This fascinated Aizawa. A hyper-specialized mutation. He isn't a god; he's a highly tuned instrument. His upper body only exists to withstand the G-forces of his lower body.

In the standing long jump, Bakugo used his explosions to clear the sandbox entirely. Izuku stepped up to the edge of the sand. He crouched, completely ignoring his arms, and simply kicked off. He leaped so high and so far that he completely bypassed the sandbox, soaring in a massive arc and landing softly on the grass thirty feet beyond it. 

Finally, they reached the softball throw. 

Uraraka touched the ball, removing its gravity, and threw it. The tracker read Infinity, drawing massive cheers from the class. 

"Midoriya, your turn," Aizawa said, tossing him a ball. 

Izuku caught it. He walked into the pitching circle. He knew his arm couldn't throw the ball very far. 85 kg of grip strength translated to a decent pitch, maybe 70 meters, but it wouldn't put him at the top of the leaderboard. 

Izuku looked at Aizawa. "Sensei, the rules state anything goes as long as I remain in the circle, correct?"

Aizawa’s tired eyes narrowed. "That is correct. Use whatever method you deem most logical."

Izuku dropped the ball on the ground. 

The class murmured in confusion. "Is he giving up?" 

Izuku took two steps back. He took a deep breath. He focused intensely on the mental switch in his head. Blunt force only. Do not deploy the claws. Maximize kinetic transfer without piercing the sphere.

Suddenly, Aizawa’s hair flared up. His eyes flashed red. He stared directly at Izuku. Erasure. 

Aizawa couldn't erase a mutant Quirk completely. He couldn't make Izuku's tail vanish or his legs turn human. But he could erase the Quirk factors that powered them—the hyper-dense muscle fiber, the kinetic resistance, the supernatural elasticity. If Aizawa was right, Izuku's legs would suddenly feel incredibly heavy and weak. 

Izuku felt the sudden, jarring drop in his power. The ambient hum of kinetic energy in his veins vanished. His legs felt like lead. 

He paused, looking up at Aizawa. 

"Your Quirk is inherently lethal, Midoriya," Aizawa said coldly, his voice carrying over the silent field. "I read your file. You possess a pair of eight-inch keratin scythes that can shear through steel. If you try to kick that ball with your full power and you miscalculate even slightly, your claws will deploy out of instinct. You won't throw the ball; you will shred it, and the resulting shockwave could severely injure the students standing behind you."

Bakugo scoffed loudly. "He's right. The damn dinosaur is going to kill someone."

Aizawa kept his glowing red eyes fixed on Izuku. "You have immense power, but power without control is a liability. Are you going to be a hero, or are you just a beast in a uniform?"

Izuku didn't get angry. He didn't feel insulted. He felt understood. Aizawa wasn't being cruel; he was being analytical. He was testing Izuku's psychological discipline.

Izuku looked down at the ball. He closed his eyes. He didn't focus on his muscles. He focused on his mind. He remembered the long, grueling months at Dagobah Beach. He remembered the thousands of ruined watermelons. He remembered the sheer, painstaking agony of learning to suppress his predatory nature.

Izuku opened his eyes. They were wide, human, and radiating absolute, serene confidence. 

"I am a hero, Aizawa-sensei," Izuku said softly. "You can let go."

Aizawa blinked. His hair fell back down. His eyes returned to normal. 

The power rushed back into Izuku’s legs like a tidal wave. He didn't hesitate. He stepped forward, planting his left foot firmly in the dirt. He spun his body violently, using his heavy tail as a counterweight. His right leg whipped around in a devastating, blindingly fast roundhouse kick. 

Keep the claws up. Use the bone of the heel. Perfect center of mass.

THOOM!

The impact sounded like a bomb going off. The shockwave kicked up a massive ring of dust around the circle. The baseball deformed into an oval under the immense blunt-force pressure before it was violently launched into the sky. It shot upward at a 45-degree angle, tearing through the clouds like a meteor, leaving a visible slipstream in the air. 

Izuku completed his spin, coming to a perfect, balanced stop. He looked down at his foot. The massive sickle claw remained securely sheathed, locked tightly against his instep. He hadn't cut the ball. He had bludgeoned it with surgical precision.

Aizawa looked down at his digital tracker. It beeped. He turned it around. 

845.3 meters.

"He... he kicked it!" Kaminari yelled, gripping his hair. "He kicked it further than Bakugo threw it!"

"And he didn't even use those scary claws!" Mina cheered. 

Bakugo stood frozen, his red eyes twitching. Eight hundred and forty-five meters. With a single, blunt-force kick. He didn't even use his lethal move. He's holding back. HE'S STILL HOLDING BACK.

"Deku!" Bakugo roared, losing his mind. Sparks erupted from his palms as he lunged forward, pure fury driving him. "Tell me how you did that, you damn mutant! You think you're better than me?!"

Before Bakugo could take three steps, a thick gray cloth wrapped tightly around his torso, binding his arms to his sides. He was yanked backward, struggling fruitlessly against the capture weapon. 

"What the... this cloth is stiff!" Bakugo grunted. 

"It's a carbon fiber alloy woven with steel wire," Aizawa said, his eyes glowing red once more, erasing Bakugo's explosions. "Stop using your Quirk so recklessly, Bakugo. You're giving me dry eye."

Aizawa released Bakugo, who stumbled forward, glaring daggers at Izuku. Izuku simply offered a polite nod and walked back to the group.

Aizawa looked at the green-haired boy. I tried to rattle him. I tried to provoke his feral instincts. He didn't even flinch. His psychological control over his own lethality is absolute. He possesses the physical tools of an apex villain, but the disciplined mind of a top-tier hero. Aizawa allowed a small smirk to cross his face. You found a good one, All Might.

"Alright, time's up," Aizawa announced. "I'll display the rankings all at once."

A holographic screen appeared. Izuku scanned the list. 

1. Momo Yaoyorozu

2. Shoto Todoroki

3. Izuku Midoriya

4. Katsuki Bakugo

...

20. Minoru Mineta

Mineta, a short boy with purple spheres on his head, fell to his knees in despair. 

"Oh, and by the way, the expulsion was a logical deception," Aizawa said casually, turning to walk away. "It was meant to draw out your best performances. You're all safe."

The class screamed in shock, though Momo Yaoyorozu sighed, noting it was obvious. 

Izuku exhaled a long breath, his tail dropping in relief. The first hurdle was cleared. But as he looked over at Bakugo, he saw the explosive boy trembling with barely contained rage. The real test, Izuku knew, was still to come.

The afternoon sun filtered through the high windows of the U.A. prep rooms as Izuku pulled on his hero costume for the first time. 

It was a masterpiece of tactical design, courtesy of the U.A. Support Course, specifically tailored to accommodate his unique physiology. The base suit was a sleek, dark green combat bodysuit made of a highly breathable, kinetic-absorbent fabric. It was sleeveless, exposing his heavily muscled arms, but featured thick, shock-absorbing bracers on his forearms to protect him if he needed to block. 

The lower half of the suit was where the real engineering shone. The pants flared widely at the knees, heavily padded to protect the complex inverted joints of his digitigrade legs. A reinforced slit at the lower back allowed his powerful, scaled tail complete freedom of movement. But the most crucial element was his footwear. 

Izuku didn't wear boots. Normal boots would restrict his toes and blunt his natural weapons. Instead, he wore custom-forged, open-toed combat sabatons. They strapped securely over the bridge of his scaly feet and wrapped tightly around his ankles, providing immense joint support. His massive sickle claws, however, were left completely exposed, gleaming dangerously against the dark green metal of the sabatons. Attached to his waist was a utility belt containing basic first-aid supplies and a small, collapsible grappling hook. 

He pulled a metallic, mouth-guard-style respirator up over his lower face—a stylistic homage to his predatory nature and a functional tool for filtering smoke and gas. 

Izuku walked out of the tunnel and into Ground Beta, a massive, artificial cityscape designed for urban combat training. 

"THEY SAY THE CLOTHES MAKE THE PRO, YOUNG MEN AND WOMEN!" 

All Might stood in the center of the street, fully buffed up, wearing his spectacular Silver Age costume. He surveyed the class with a booming laugh. "AND LOOKING AT YOU NOW, I SEE A BUNCH OF TRUE HEROES!"

All Might’s eyes lingered on Izuku. He felt a swell of pride. The boy didn't look like a nervous kid anymore. With the dark green tactical suit, the exposed claws, and the intense, focused posture, Izuku looked like a seasoned pro—a silent, lethal hunter ready for the wild.

"TODAY, WE WILL BE CONDUCTING TWO-ON-TWO INDOOR BATTLE TRIALS!" All Might explained. "VILLAINS HAVE HIDDEN A NUCLEAR WEAPON INSIDE A BUILDING! THE HEROES MUST INFILTRATE AND EITHER SECURE THE WEAPON OR CAPTURE THE VILLAINS WITHIN THE TIME LIMIT!"

All Might held up a box. "WE WILL DRAW LOTS TO DETERMINE TEAMS!"

Izuku drew the letter A. He looked around and saw Uraraka holding up the same letter. 

"Oh, yay! We're a team, Midoriya!" she cheered, jogging over in her pink-and-black, astronaut-inspired suit. "This is going to be great! With your speed and my gravity, we'll be unstoppable!"

Izuku smiled behind his respirator, his tail wagging slightly. "It's great to work with you, Uraraka. I'll do my best to support you."

All Might drew the first matchup from the boxes. 

"TEAM A WILL BE THE HEROES! TEAM D WILL BE THE VILLAINS!"

Izuku’s blood ran cold. He looked across the crowd. 

Standing in Team D was Tenya Iida, heavily armored in his white knight-like suit. And standing next to him, wearing massive, grenade-shaped gauntlets and a mask with sharp, flared explosions... was Katsuki Bakugo.

Bakugo turned his head. His crimson eyes locked onto Izuku. The sheer, unadulterated killing intent radiating from Bakugo was palpable. He didn't just want to win this exercise. He wanted to break the dinosaur that had humiliated him. 

"VILLAINS, YOU HAVE FIVE MINUTES TO PREPARE INSIDE THE BUILDING! HEROES, YOU WILL INFILTRATE AFTER!"

As Bakugo and Iida walked into the building, Uraraka looked nervously at Izuku. "Um, Midoriya? Bakugo looks like he wants to murder you."

Izuku sighed, his tail swishing in tight, agitated arcs. "He does. Kacchan and I have... a complicated history. He’s incredibly strong, and his combat instincts are flawless. But he's driven by pride. He’s going to ignore the objective and come straight for me."

"What should we do?" she asked.

Izuku’s eyes narrowed, shifting into full tactical mode. "When we go in, he's going to ambush us. His explosions are loud and bright, meant to disorient. I can track his movements, but the corridors are tight. If I use my claws, I could severely injure him or collapse the building. I have to fight him using only blunt force and evasion."

He turned to Uraraka. "When he attacks me, I'll draw his aggro. I want you to slip away and find the weapon. Iida is likely guarding it. Iida is fast, so use your Quirk to float the surrounding debris and create a barricade. I will handle Kacchan."

Uraraka nodded, her face setting into a determined scowl. "Right. I trust you."

A buzzer echoed across the cityscape. 

"BEGIN!" All Might announced over the PA system.

Izuku and Uraraka entered the building through a first-floor window. The interior was dark, lit only by emergency lights. Concrete pillars and narrow hallways created a claustrophobic labyrinth. 

Izuku took the lead. He walked in utter silence. His digitigrade feet, lacking heavy human heels, allowed him to move like a ghost. His ears twitched, rotating like radar dishes, picking up the subtle hum of the building's pipes and the faint sound of footsteps on the floor above. 

"He's not on the second floor," Izuku whispered, using hand signals to guide Uraraka. "The vibrations feel too heavy for a single person. He's waiting near the stairs."

They rounded a corner, approaching the main stairwell. 

Izuku’s kinetic vision suddenly spiked. He smelled it before he saw it. The distinct, acrid scent of burnt caramel. 

Nitroglycerin.

Izuku grabbed Uraraka by the shoulder and violently threw her backward, throwing himself in the opposite direction. 

BOOM!

The wall next to them exploded in a blinding flash of fire and concrete. The shockwave rattled Izuku’s teeth. Smoke flooded the hallway. 

From the smoke, Katsuki Bakugo emerged, his right gauntlet smoking, a manic, terrifying grin on his face. "Come on, Deku! Don't dodge! Show me that apex power of yours!"

Bakugo didn't wait for the smoke to clear. He used a smaller explosion from his left hand to propel himself forward at blistering speed, aiming a massive right hook directly at Izuku’s face. 

He's fast, Izuku thought, his predatory brain processing the attack in slow motion. But he's telegraphing his swings by pulling his shoulder back to brace for the recoil.

Izuku didn't block. Blocking an explosion would shatter his arms. He relied entirely on his legs. He dropped incredibly low, bending his knees backward, passing entirely underneath Bakugo’s swinging arm. 

As Bakugo sailed over him, Izuku whipped his thick, scaly tail around in a brutal leg sweep. 

The heavy tail slammed into Bakugo’s ankles. The explosive boy grunted in surprise as his feet were swept entirely out from under him, sending him crashing face-first into the concrete floor. 

"Go, Uraraka!" Izuku shouted. 

Uraraka didn't hesitate. She scrambled past the fallen Bakugo and darted up the stairwell, disappearing into the upper floors. 

Bakugo vaulted back to his feet, enraged. He didn't even look at Uraraka. His eyes were locked entirely on Izuku. "You think a cheap tail sweep is going to stop me?! I'm going to blow those dinosaur legs right off your body!"

Bakugo lunged again, unleashing a rapid-fire flurry of explosions. Boom! Boom! Boom!

The tight hallway became a furnace of heat and shrapnel. For a normal human, there was no room to dodge. But Izuku wasn't a normal human. He was an apex predator trapped in a cage, and the walls were his playground. 

Izuku leaped sideways, his clawed toes sinking into the concrete wall to his left. He rebounded instantly, shooting across the hallway to the right wall, then off the ceiling, bouncing through the narrow corridor like a lethal, green rubber band. Bakugo’s explosions blew massive holes in the walls and floor, but he was always a fraction of a second too late. Izuku was moving in three dimensions, leaving afterimages in the smoke.

"Stand still, you damn coward!" Bakugo roared, spinning around and firing a massive blast at the ceiling where Izuku had just been.

Izuku dropped from the ceiling behind Bakugo. He spun mid-air, bringing his heavy heel down in an axe-kick aimed at the back of Bakugo's neck. 

But Bakugo’s combat instincts were phenomenal. Hearing the wind displace behind him, Bakugo twisted his body and fired an explosion upward, catching Izuku squarely in the chest. 

Izuku grunted in pain as the concussive force blasted him backward. He hit the ground, sliding back several feet, his claws carving deep grooves into the floor to arrest his momentum. His combat suit was scorched, but the kinetic-absorbent fabric had taken the brunt of the heat. 

"Got you," Bakugo panted, a dark, manic look in his eyes. 

In the observation room, the class was watching the monitors in terrified silence. 

"Bakugo is insane!" Kirishima gasped. "He's trying to kill him! And Midoriya isn't even fighting back! He's just dodging and using his tail!"

"Midoriya is at a severe disadvantage," Todoroki noted quietly, his heterochromatic eyes narrowed. "His Quirk is highly lethal. In a confined space, if he uses his claws, he risks fatally wounding Bakugo or bringing the building down on both of them. Bakugo doesn't care about the collateral damage. Midoriya is handicapping himself to protect his opponent."

All Might gripped the microphone. He knew Todoroki was right. Izuku was fighting the hardest battle of his life: holding back a monster while fighting a madman.

Back in the hallway, Bakugo raised his right arm. He placed his left hand on the pin of his massive, grenade-shaped gauntlet. 

"They're fully loaded, Deku," Bakugo growled, his voice trembling with a terrifying mix of rage and desperation. "My gauntlets store up my sweat. When I pull this pin, the blast will be concentrated enough to vaporize this entire hallway."

Izuku’s eyes widened. He wouldn't. The sheer concussive force inside a closed space would rupture organs.

"YOUNG BAKUGO, STOP!" All Might’s voice boomed over the PA system. "IF YOU FIRE THAT, THE MATCH IS OVER! YOU'LL KILL HIM!"

Bakugo’s eyes were wild. He didn't care about the exam. He only cared about proving that he was the apex. That the dinosaur was beneath him. 

"He won't die if he dodges!" Bakugo screamed, and he pulled the pin. 

FWOOOOOOSH!

A column of pure, blinding white fire erupted from the gauntlet. The explosion was astronomically large, filling the entire hallway. The concrete walls instantly superheated, cracking and blowing outward. A massive, concussive shockwave tore through the building, shaking the very foundations. 

In the observation room, the screens went white with static. The students screamed. 

On the fourth floor, Uraraka and Iida were thrown to the floor by the sheer force of the tremor. 

Down in the second-floor hallway, the smoke was thicker than a heavy fog. The emergency lights were shattered. The only illumination came from the glowing, molten edges of the destroyed concrete. 

Bakugo stood at the end of the hallway, panting heavily, his right arm trembling from the sheer recoil of the blast. The hallway in front of him was utterly annihilated. 

"I win," Bakugo gasped, forcing a deranged smile. "I'm the best."

Click.

Bakugo froze. It was a sound so soft it should have been imperceptible over the ringing in his ears, but it pierced his primal brain like an ice pick. The sound of dense keratin locking into place. 

High above Bakugo, hidden entirely within the thick cloud of black smoke near the ceiling, a pair of glowing, vertical-slit emerald eyes opened. 

Izuku hadn't dodged backward. When Bakugo had pulled the pin, Izuku had leaped forward and up, launching himself directly over the blast wave, using the thick smoke as perfect camouflage. 

Bakugo looked up, his crimson eyes shrinking in absolute terror. 

Izuku was falling from the ceiling, completely inverted, directly over Bakugo. His digitigrade legs were pulled back, coiled with the kinetic energy of a falling meteor. His sickle claws were out, glowing with a terrifying, lethal intent. 

For a fraction of a second, Bakugo saw his own death. He saw the claws coming down. He saw the dinosaur, the apex predator, moving in for the kill. 

But Izuku Midoriya was not a killer. 

Switch Off.

In the microsecond before impact, Izuku’s sickle claws retracted violently, snapping upward with a loud clack. He angled his foot, presenting the flat, hyper-dense bone of his heel. 

"Blunt-Force Talon Leap Strike!"

Izuku’s heel slammed directly into the center of Bakugo’s chest. 

The impact was surgical and devastating. The kinetic force wasn't designed to pierce; it was designed to overwhelm the nervous system. The strike instantly knocked the wind out of Bakugo’s lungs, collapsing his stance and driving him straight down into the floor. 

CRACK!

The concrete beneath Bakugo cratered under the sheer, unadulterated weight of the blow. Bakugo bounced once, his eyes rolling back in his head, completely unconscious before he even realized he had been hit. 

Izuku landed perfectly over his fallen rival, dropping into a deep crouch. His chest heaved as he pulled oxygen through his respirator. His tail whipped out, slapping the ground once to stabilize his stance. 

He looked down at the unconscious Bakugo. He had done it. He had faced the most explosive, violent force in his class, and he had subdued him without shedding a single drop of blood. 

He reached down and gently pulled a strip of capture tape from his belt, wrapping it around Bakugo’s wrists. 

He tapped his earpiece. "Uraraka. Kacchan is captured and unconscious. Proceed with the objective."

Up on the fourth floor, Uraraka grinned. She used her Quirk on a massive pillar that had collapsed from Bakugo's blast, swinging it like a baseball bat. Iida, distracted by the massive explosion downstairs, was caught off guard and knocked away from the paper-mâché nuclear weapon. 

Uraraka leapt forward and slammed her hands onto the warhead. "Secured!"

The buzzer blared across the facility. 

"HERO TEAM... WINS!" All Might’s voice announced, thick with awe and relief. 

In the observation room, the class erupted into cheers, completely blown away by the display. 

"Did you see that?!" Kirishima yelled, pumping his fists. "He leaped through the explosion! That was so manly!"

"The control," Momo Yaoyorozu whispered, placing a hand over her mouth. "He had the perfect angle for a lethal strike, but he retracted his claws at the absolute last second to deliver a non-lethal concussive blow. The spatial awareness required to execute that mid-air is... it's beyond professional level."

Aizawa, standing in the shadows at the back of the room, watched the monitor silently. He watched Izuku gently pick up the unconscious Bakugo, slinging the explosive boy over his shoulder to carry him to the infirmary. 

He tamed the beast, Aizawa thought, a genuine sense of respect settling in his chest. He proved that his heart is stronger than his instincts. You were right, All Might. This kid... he's going to change the world.

The interior of the U.A. transport bus hummed with the steady vibration of the engine, a low, rhythmic sound that Izuku Midoriya found surprisingly soothing. He sat near the back, his digitigrade legs folded neatly beneath his seat. His thick, scaly tail rested across his lap like a coiled, green serpent, though the tip occasionally twitched with nervous energy. 

He was wearing his dark green tactical hero suit, his massive sickle claws fully exposed in his custom sabatons. He kept his feet tucked back, hyper-aware of his surroundings. 

"Hey, Midoriya," a blunt, slightly croaky voice called out. 

Izuku looked up. Tsuyu Asui, a girl with wide, unblinking eyes and a distinct frog-like mutation, was leaning over the aisle. She pressed a finger to her chin. "I generally say whatever comes to mind. Your Quirk is really similar to mine, in a way. We both have animal mutations that give us strong legs."

Izuku blinked, slightly caught off guard. "Oh, um, yes! I suppose we do. You're a frog mutation, right, Asui?"

"Call me Tsu," she corrected smoothly. "But my Quirk is amphibian. Yours is definitely reptilian. Actually, no, looking at your legs and that tail... you're a dinosaur, aren't you?"

The bus suddenly went quiet. The other students turned to listen. Midoriya’s Quirk had been the talk of Class 1-A since the apprehension test and the combat trials. He was quiet, polite, and constantly scribbling in his notebooks, yet he possessed the physical capabilities of a biological weapon. 

"Yes," Izuku said, shifting slightly under the stares. "It's a mutant-type Quirk called Apex Deinonychus. My lower body shares the anatomical structure of a raptor. It gives me high-density muscle fibers, inverted joints for jumping, and..." He hesitated, glancing down at his feet. "...and the claws."

"It's super flashy!" Eijiro Kirishima grinned, leaning over from the row ahead. "And crazy strong! You sent Bakugo flying with just a heel strike! My Quirk is Hardening. It's good for taking hits and brawling, but it's not nearly as cool as being a human raptor."

"I think your Quirk is amazing, Kirishima," Izuku replied earnestly. "Hardening is incredibly versatile. It makes you a perfect vanguard in a team setting. You can draw aggro and protect civilians while minimizing personal damage."

Kirishima beamed. "Thanks, man! That's the goal!"

"If we're talking about flashy and strong, though, you've got to look at Todoroki, Bakugo, and Midoriya," Denki Kaminari chimed in, leaning back with his hands behind his head. "Though, Bakugo's always so mad, he'll never be a popular pro."

"What did you say, you damn extra?!" Bakugo roared from the front of the bus, leaping out of his seat with sparks flying from his palms. "I'll be the number one hero, and I'll kill anyone who says otherwise!"

"See?" Kaminari pointed, unfazed. "We haven't even known each other a week, and it's already universally recognized that your personality is flaming garbage mixed with sewage."

As Bakugo began screaming expletives, struggling against Aizawa’s capture tape to get to Kaminari, Izuku smiled softly beneath his respirator mask. It was loud, chaotic, and entirely normal. For the first time in his life, Izuku felt like he belonged. He wasn't the scary monster of Aldera Junior High anymore. He was just another student at U.A.

The bus finally slowed to a halt. 

"Settle down. We're here," Aizawa’s tired voice cut through the noise. 

The class filed off the bus and found themselves standing before a colossal, domed structure that looked like a futuristic stadium. The sheer scale of it was breathtaking. 

Waiting for them at the entrance was a figure in a puffy, white astronaut suit. 

"Hello, everyone! I've been waiting for you!" 

"It's the Space Hero, Thirteen!" Uraraka squealed, practically vibrating with excitement. "They're a rescue specialist! I love Thirteen!"

Thirteen led the students inside. The interior of the dome was a sprawling, multi-biome marvel. There was a ruined city, a massive artificial lake with a shipwreck, a mountainous zone, a fiery conflagration zone, and a central plaza connecting them all. 

"Welcome to the Unforeseen Simulation Joint! Or, as I like to call it, the USJ!" Thirteen announced. 

The class gasped in awe, but Thirteen held up a hand, their posture turning serious. 

"Before we begin, I have one or two... or three... or four things to say," Thirteen began. "As you know, my Quirk is Black Hole. It can suck up anything and turn it to dust. It has saved many people from disasters. However..." Thirteen’s voice grew heavy. "...it is also a power that could easily be used to kill."

Izuku froze. His tail stopped swaying. His emerald eyes locked onto the pro hero. 

"In our superhuman society, Quirks are heavily regulated, and the requirements for lawful use are strictly enforced," Thirteen continued. "But please do not forget that many of you possess powers that can go out of control. One wrong move, one lapse in judgment, and you could easily end a life."

Izuku swallowed hard. His toes curled involuntarily, the massive sickle claws clicking softly against the metal of his sabatons. Thirteen was speaking directly to the fear that Izuku carried every single day. 

"Aizawa's physical fitness test showed you your true potential," Thirteen said, spreading their arms. "All Might's battle trials taught you the danger of using those powers against others. Today, you will learn how to use your Quirks to save lives! You do not have powers to harm others. You have powers to help! That is all. Thank you for listening."

The class erupted into applause. Izuku felt a profound sense of validation wash over him. That's exactly it, he thought, clenching his fists. I am a weapon, but I am a weapon meant to protect.

"Right," Aizawa said, stepping forward. "First, we'll divide into—"

Aizawa stopped. 

The massive lights illuminating the USJ suddenly flickered and died, plunging the dome into a dim, eerie twilight. The large fountain in the center of the central plaza sputtered and stopped flowing. 

Izuku’s head snapped toward the plaza. His ears swiveled, the tiny hairs on the back of his neck standing up. A deeply buried, primal instinct—the instinct that told prey when a predator had entered the clearing—screamed in his mind. But Izuku wasn't prey. He was an apex predator, and he smelled a profound, overwhelming malice. 

Down in the plaza, the air itself seemed to tear open. A swirling vortex of purple-black mist expanded outward like a cancerous bruise on reality. 

"Gather together and don't move!" Aizawa barked, his voice laced with an urgency the students had never heard from him. "Thirteen, protect the students!"

"What is that?" Kirishima asked, squinting down at the plaza. "Is this like the entrance exam? Does the training start right away?"

Izuku’s kinetic vision flared. His pupils contracted into razor-thin vertical slits. He didn't see robots emerging from the mist. He saw people. 

Dozens of them. Men and women holding pipes, swords, and guns. And leading them were three distinct figures. A man made entirely of the dark mist. A tall, lanky man covered in disembodied, grayish hands. And standing beside them, a towering, hulking beast with exposed brain matter, a beak-like mouth, and muscles that defied human anatomy. 

"Don't move," Aizawa ordered, sliding his yellow goggles over his eyes. His capture scarf began to levitate around him like angry serpents. "Those are real villains."

The word hung in the air, heavy and suffocating. Villains. 

"Villains?! No way! How did they get into a U.A. facility?!" Mineta panicked, trembling violently. 

Down in the plaza, the man covered in hands looked up at the staircase. "Where is he? We went through all the trouble of bringing this whole crowd... and All Might, the Symbol of Peace, isn't here. I wonder if he'll show up if we kill some kids?"

Izuku’s blood ran cold. They're here to kill All Might. And they brought an army to do it.

Aizawa didn't hesitate. He leaped down the massive staircase, plunging entirely alone into the sea of dozens of villains. 

Izuku watched in awe as his teacher fought. Aizawa was a master of close-quarters combat. He darted between the thugs, erasing their Quirks with a glance and using his capture scarf to whip, bind, and smash them against the concrete. He was a phantom, moving with surgical precision. 

But Izuku’s analytical mind was running a thousand calculations a second. Aizawa-sensei's Quirk isn't suited for front-line, prolonged group battles. He excels at stealth and capture. He's diving into a war of attrition just to buy us time. He's going to exhaust his eyes.

"We need to evacuate!" Thirteen yelled, ushering the students toward the heavy steel doors. 

They ran, but the purple mist suddenly expanded, shooting up from the plaza and materializing right in front of the exit, blocking their path. The mist coalesced, forming glowing yellow eyes. 

"I am afraid I cannot allow that," the mist entity spoke, its voice deep and chillingly polite. "We are the League of Villains. It may be presumptuous of us, but we have invited ourselves into the home of the heroes in order to have All Might take his final breath."

Bakugo and Kirishima didn't wait. With simultaneous roars, they leaped forward, Bakugo unleashing a massive explosion and Kirishima throwing a hardened punch directly into the mist. 

"Did you consider that you'd get beaten by us before you could do it?!" Kirishima yelled as the smoke cleared. 

But the mist wasn't damaged. The physical attacks had passed right through it. 

"My, that was close," Kurogiri chuckled darkly. "Yes, you are students, but you are also golden eggs. It is my job to scatter you, and torture you to death."

The mist erupted outward, engulfing the entire class. 

Izuku felt the ground vanish beneath his feet. The world dissolved into a swirling vortex of purple and black. There was no up, no down, only a sickening sense of vertigo. He reflexively curled his body, wrapping his heavy tail around himself to protect his core. 

A moment later, he was violently ejected from the portal. 

Izuku opened his eyes. He wasn't in the air. He was falling toward a massive body of water. 

He splashed down, the cold water of the Shipwreck Zone rushing over his tactical suit. The sudden change in environment was jarring. Deinonychus, the genetic ancestors of his Quirk, were terrestrial hunters. They ruled the land. They were not aquatic. 

Izuku held his breath, opening his eyes underwater. The artificial lake was deep. But more alarmingly, the water wasn't empty. 

"Look what fell right into our laps!" 

"A kid! Easy pickings!"

Half a dozen villains with aquatic-based Quirks—gills, webbed hands, shark-like teeth—were darting toward him through the water like torpedoes. They held rusted blades and harpoons. 

Izuku didn't panic. Panic was for prey. 

Adapt. 

Izuku analyzed his own biomechanics. His digitigrade legs possessed an astronomical amount of explosive kinetic energy. His inverted joints acted like pistons. His tail was thick, muscular, and aerodynamically perfect. 

I'm not a land predator right now, Izuku realized, his eyes narrowing into slits as he stared at the approaching aquatic villains. I am a biological submarine.

He pulled his arms tight against his sides to reduce drag. He extended his powerful legs backward. And then, he kicked. 

The force of his frog-kick was so violently powerful that it created a visible cavitation bubble—a localized vacuum of boiling water—right behind his feet. Izuku shot forward like a fired torpedo. He moved so fast that the aquatic villains barely had time to register his trajectory. 

"What the hell?!" a shark-faced villain garbled, trying to turn. 

Izuku didn't engage them. He zipped past the villains, his tail acting as a flawless rudder, allowing him to bank sharply through the water. He scanned the surface and saw a large yacht rocking in the center of the zone. 

He kicked again, rocketing toward the surface. He breached the water like a majestic, green-scaled dolphin, soaring twenty feet into the air. He landed heavily on the deck of the yacht, his sickle claws biting into the fiberglass deck to anchor himself. 

"Midoriya!" 

Izuku spun around. Huddled against the railing of the yacht were Tsuyu and Mineta. Mineta was crying hysterically, clutching his head, while Tsuyu looked remarkably calm, though her wide eyes betrayed her tension. 

"Tsu! Mineta! Are you both okay?" Izuku asked, dropping into a defensive crouch and scanning the water below. 

"I'm fine. Tsu saved me," Mineta sobbed. "But we're going to die! Look at the water! There are dozens of them down there! They're waiting for us!"

Izuku looked over the railing. The water surrounding the yacht was churning. Fins broke the surface. Villains were circling the boat, holding tridents and laughing. They were waiting for the heroes to make a move. 

"They have the geographical advantage," Tsuyu croaked, sticking to the wall of the cabin. "They know this is a water zone. They're aquatic types. If we go in there, they'll tear us apart. What do we do, Midoriya?"

Izuku’s mind raced. He pulled his respirator down to speak clearly. "They have the advantage, yes. But they also made a tactical error."

Mineta grabbed his hair. "Error?! They have us surrounded on a sinking ship!"

"Exactly," Izuku pointed to the villains. "They're waiting. They don't know what our Quirks are. If they knew my Quirk was leg strength, they would have tried to sink the ship immediately and force me into a grapple underwater where I can't build momentum. But they're being cautious."

Izuku stood up. He walked to the edge of the yacht. He looked down at his clawed feet. 

"Tsu, Mineta," Izuku said, his voice dropping an octave, taking on the calm, chilling resonance of the apex predator. "I need you to grab onto the railing. Hold on as tight as you can. When I create an opening, Tsu, grab Mineta and use your frog leap to clear the water and reach the shore."

"What are you going to do?" Tsuyu asked. 

Izuku’s sickle claws extended with a sharp, lethal snikt. The eight-inch scythes locked into place. 

"I'm going to change the geography," Izuku said. 

Izuku vaulted over the railing. 

"He jumped!" a villain in the water yelled. "Get him!"

But Izuku didn't dive into the water. He landed perfectly on the surface of the water, and in the fraction of a second before he could sink, he spun violently. 

He initiated a localized, blunt-force variation of his leap strike, but he didn't aim at a target. He aimed at the lake itself. 

Izuku’s massive legs churned the water. He kicked with such astronomical velocity, torque, and power that the water had nowhere to go but out and around. He became a human centrifuge. 

A massive whirlpool erupted in the center of the lake. 

The sheer G-force of the vortex was catastrophic. The aquatic villains, entirely reliant on swimming, were caught in the overwhelming current. They screamed as they were sucked into the spinning funnel of water, completely losing control of their bodies. 

"Ahhhhh!" 

"I can't swim against this!" 

"Help!"

The whirlpool grew to thirty feet in diameter, pulling all twenty villains into a clustered, disoriented mass at the center. 

Izuku was suspended in the air just above the vortex, bouncing rapidly off the churning walls of water like a skipping stone. Now that the villains were clustered, he saw they were desperately clinging to broken pieces of debris, rusted boats, and their weapons to stay afloat. 

Switch On. 

Izuku didn't hold back. Since his targets were not human flesh, but inanimate metal and fiberglass, he unleashed the sickle claws. 

He ricocheted off the water and dove directly into the center of the whirlpool. He became a blender of razor-sharp keratin and compressed wind. He pinballed between the villains. He didn't touch a single hair on their heads. But in less than three seconds, every single boat was cleanly bisected. Every harpoon was snapped in half. Every trident was shredded into metal splinters. 

Izuku bounced off a sinking boat hull and rocketed out of the whirlpool, soaring in a massive arc toward the shoreline of the plaza. 

The whirlpool collapsed violently, dumping the terrified, unarmed, and completely disoriented villains into a tangled, drowning pile of scrap. 

"Now, Tsu!" Izuku shouted mid-air. 

Tsuyu didn't waste a second. She grabbed Mineta by his cape and executed a massive, fifty-foot frog leap, sailing entirely over the ruined villains and landing safely on the concrete shore of the central plaza, right next to where Izuku touched down. 

Mineta hit the concrete and kissed it. "We're alive! Midoriya, you're a freak! A beautiful, terrifying freak!"

Tsuyu looked at the water, then at Izuku's heavy panting. His claws had already retracted into their safe position. "That was incredible, Midoriya. You completely disabled them without shedding a drop of blood."

"It's... just basic crowd control," Izuku gasped, pulling oxygen into his lungs. Using that much sustained leg power on a fluid medium was exhausting. 

But Izuku didn't have time to rest. The sound of a sickening crack echoed through the plaza. 

Izuku’s head snapped up. 

Aizawa was on the ground. 

Izuku, Tsuyu, and Mineta crept to the edge of the plaza, hiding behind a low concrete wall. They looked out at the center of the USJ. 

The villains had been thinned out significantly by Aizawa, but the Pro Hero was covered in blood. He was panting heavily, his goggles cracked. 

Standing over him was the towering, hulking beast with the exposed brain—the Nomu. 

Shigaraki, the man covered in hands, stood a few feet away, scratching his neck violently. "You're cool, Eraser Head. You really are. But your Quirk is suited for short-term stealth, not fighting an army. And it certainly doesn't work on him."

Shigaraki pointed. 

The Nomu moved with a speed that shouldn't have been possible for a creature of its size. It appeared behind Aizawa and grabbed his arm. With a horrifying, effortless crunch, the Nomu snapped Aizawa’s arm backward. 

Aizawa screamed, a sound that made Izuku’s blood freeze. 

"He's the anti-Symbol of Peace," Shigaraki giggled darkly. "The bio-engineered Nomu. His Quirks are Shock Absorption and Super Regeneration. You can't erase pure, unadulterated physical stats."

The Nomu slammed Aizawa face-first into the concrete, shattering the ground. It grabbed Aizawa’s other arm and snapped it like a twig. 

Mineta covered his mouth, sobbing silently in absolute terror. Tsuyu’s eyes were wide with horror. 

Izuku’s heart pounded against his ribs. His kinetic vision processed every drop of blood, every micro-movement of the Nomu’s muscles. It's a monster. A true monster. It eclipsed Aizawa completely. If I jump out there... what can I do against something that absorbs shock?

"Tomura Shigaraki," the misty Kurogiri materialized beside the hand-villain. 

"Kurogiri. Did you kill Thirteen?" Shigaraki asked. 

"I incapacitated Thirteen, but... one of the students managed to escape through the doors. He is likely running to summon All Might."

Shigaraki stopped scratching. He stood completely still. 

"Game over," Shigaraki whispered. "It's game over. If dozens of pros show up, we'll be wiped out. We have to retreat."

Mineta let out a quiet sigh of relief. "They're leaving. Thank god. We're saved."

"But before we go..." Shigaraki turned his head slowly. His red eyes locked directly onto the low wall where Izuku, Tsuyu, and Mineta were hiding. "...let's leave a little present for the Symbol of Peace. Let's smash some of his precious students."

Shigaraki vanished. 

He didn't have a speed Quirk, but his baseline physical agility was terrifying. In the blink of an eye, Shigaraki crossed the distance, appearing right in front of the wall. 

Time dilated. The adrenaline hyper-accelerated Izuku’s predatory brain. 

Shigaraki reached his hand over the wall. He wasn't aiming for Izuku. He was aiming for Tsuyu. 

His five fingers, gray and decaying, descended toward Tsuyu’s face. Izuku knew what that Quirk did. He had watched Shigaraki decay Aizawa’s elbow earlier. If all five fingers touched Tsuyu's face, she would disintegrate into ash in seconds. 

Aizawa, battered and broken on the ground thirty feet away, forced his bloodied head up. His eyes flared red. Erasure. 

Shigaraki’s hand touched Tsuyu’s face. 

Nothing happened. 

Shigaraki blinked, looking back at Aizawa. "You really are cool, Eraser Head."

But Aizawa’s eyes were failing. The Nomu grabbed his head and slammed it into the concrete again. Aizawa’s Quirk deactivated. 

Shigaraki smirked, pressing his fingers harder against Tsuyu’s skin. The decay Quirk activated. 

Izuku Midoriya stopped thinking. 

The hero who practiced restraint, the boy who feared his own power, the student who wanted to capture villains safely... all of those identities were violently shoved aside. 

Switch On.

This was not a drill. This was not a mock battle. This was a predator threatening his pack. 

CLACK.

The sound of the sickle claws snapping into place was deafening. They didn't just deploy; they locked in with a terrifying, absolute rigidity. 

Izuku exploded from the water. 

He didn't yell. He didn't telegraph his move. He simply became a force of nature. 

Shigaraki only saw a flash of green scales in his peripheral vision. 

Izuku executed a horizontal Razor Talon Leap Strike, flying parallel to the ground just over the low wall. He didn't aim for Shigaraki’s head. He didn't aim for his heart. The hero inside Izuku still held the reins, refusing to take a life. 

But the apex predator was allowed to disable the threat. 

The eight-inch, hyper-dense keratin scythe on Izuku’s right foot flashed in the dim light of the USJ. 

SHKKK.

The sound of the vacuum shear slicing the air was followed instantly by the sickening sound of flesh parting. 

Izuku cleaved straight through Shigaraki’s extended right arm. 

He didn't amputate it completely—that would be too difficult to heal. Instead, with horrifying, surgical precision, Izuku’s claw sliced deep into the forearm, severing the flexor tendons, the radius bone, and the major muscle groups, stopping just short of the ulnar artery to prevent fatal blood loss. 

Izuku landed ten feet away, skidding on the concrete, his claws throwing sparks as he stopped his momentum. He spun around, placing himself firmly between Shigaraki and Tsuyu, his tail lashing violently behind him, his eyes glowing with an intense, vertical-slit emerald fire. 

"AGGGGGGGGHHHHH!" 

Shigaraki collapsed to his knees, clutching his ruined arm. Blood poured onto the concrete. His hand, entirely disconnected from the tendons that operated it, hung completely limp and useless. The pain was astronomical. 

"My arm! My arm!" Shigaraki shrieked, the calm, arrogant gamer persona shattering instantly, replaced by the chaotic tantrum of a wounded, murderous child. 

Kurogiri materialized beside him, his yellow eyes wide with alarm. "Tomura Shigaraki! Are you alright?!"

"Kill him!" Shigaraki screamed, pointing his trembling, bloody left hand at Izuku. The malice rolling off the villain was palpable. "Nomu! Tear that green raptor brat apart! Crush his skull!"

Behind Shigaraki, the towering, brain-exposed beast slowly turned its head. It dropped the unconscious, bleeding body of Aizawa like a broken doll. 

The Nomu let out a low, gurgling screech. Its empty, dead eyes locked onto Izuku. 

Izuku didn't flinch. He didn't back down. He pulled his respirator off his face, allowing the USJ air to fill his lungs. He felt the terrifying, oppressive weight of the Nomu’s presence. It was stronger than him. It was faster than him. It was designed to kill the greatest hero in the world. 

But as Izuku looked at Tsuyu and Mineta trembling behind him, he knew he couldn't run. 

Izuku widened his stance. His sickle claws dug deep into the concrete plaza, anchoring him to the earth. His tail swished in slow, calculated arcs. 

Shock absorption, Izuku thought, his mind crystal clear. A defensive Quirk designed to counter blunt-force trauma.

A dark, feral grin slowly pulled at the corners of Izuku’s mouth. 

Let's see how well it absorbs a pair of biological scythes.
