What if deku had mantis shrimp quirk

 

 

To understand the universe as it was meant to be seen, one must first understand the limitations of the human eye.

 

A normal human being possesses three distinct types of color-receptive cones in their retinas: red, green, and blue. With these three biological tools, the human brain paints the world in a comfortable, manageable spectrum. They see the verdant green of the grass, the brilliant azure of the sky, and the crimson flush of blood beneath the skin. It is a beautiful world, but it is an illusion of simplicity. It is a fraction of a fraction of reality, a comforting blanket thrown over the blinding, incomprehensible truth of the electromagnetic spectrum.

 

Izuku Midoriya, for the first four years of his life, lived in this simple, three-cone world.

 

He was a bright, exceptionally observant child, a boy whose world revolved around the television screen in his living room and the booming, boisterous laughter of the Number One Hero, All Might. In Izuku’s three-cone world, All Might’s costume was a brilliant mesh of primary colors—red, blue, and yellow—that stood as an undeniable beacon of safety. Izuku’s world was small, safe, and filled with a burning, singular desire: he wanted a Quirk. He wanted to be a hero.

 

In a society where eighty percent of the population possessed some form of superhuman ability, the playground was a terrifying, wonderful place. It was a testing ground for the future of humanity. Some children could stretch their fingers into vines; others could float, or turn their skin to stone, or breathe small plumes of harmless fire. And then there was Katsuki Bakugo.

 

Katsuki, Izuku’s closest childhood friend, had awakened his Quirk with the subtlety of an exploding sun. He sweat nitroglycerin. He could create concussive blasts from his palms. He was brilliant, fierce, and undeniably destined for greatness. Katsuki was the king of the playground, and Izuku, whose toes remained firmly on the ground and whose palms remained completely dry, was the loyal, trailing shadow.

 

"You're amazing, Kacchan!" Izuku would say, his large, emerald-green eyes wide with adoration.

 

Katsuki would smirk, sparks popping harmlessly off his fingertips. "Of course I am. I’m going to be the Number One Hero. I’m gonna surpass All Might. And you, Deku..." The nickname, a misreading of Izuku's name meaning 'useless', had already begun to stick. "...you just stay out of my way until you get your Quirk."

 

Izuku was waiting. His mother, Inko, could pull small objects to her. His father, Hisashi, could breathe fire. It was only a matter of time. The pediatrician had said so. His fourth birthday had come and gone, and the window for manifestation was closing, but Izuku remained optimistic. He just had to wait a little longer.

 

He had no idea that his Quirk was not late. It was simply gestating, rewriting his entire biological makeup from the marrow outward, building an architecture so complex and violent that his small, four-year-old body required every ounce of energy just to survive the transformation.

 

The awakening did not happen with a heroic leap or a sudden burst of fire. It happened on a Tuesday, at 1:14 PM, during free-coloring time at Aldera Preschool.

 

 

 

Izuku was sitting at a low, circular wooden table, gripping a yellow wax crayon in his chubby fist. He was diligently trying to color in a crude drawing of All Might. Beside him, Katsuki was aggressively scribbling a fiery explosion onto his own paper with a mixture of red and orange crayons. The classroom was filled with the low hum of twenty children humming, whispering, and the soft scraping of wax on paper.

 

It started as an itch behind Izuku's eyes.

 

He blinked, rubbing his left eye with the back of his wrist. The itch didn't fade. It deepened, burrowing into the optic nerve, slowly transforming from a dull tickle into a sharp, localized throb. Izuku sniffled, trying to ignore it, and looked back down at his paper.

 

Something was wrong with the yellow crayon.

 

Izuku frowned. He pressed the tip against the paper, but the color... the color wasn't right. It wasn't yellow anymore. It was yellow, but it was also something else. A hue he had no word for. It was a color that tasted sharp, like copper pennies on his tongue, and felt like the static on the television screen.

 

He blinked rapidly. "Huh?" he mumbled, his voice tiny in the crowded room.

 

The throb behind his eyes flared into a spike of searing heat. Izuku gasped, dropping the crayon. He brought both hands to his face. His eyes felt as though they were filled with sand, but the sand was boiling.

 

"Hey, Deku, what's wrong with you?" Katsuki's voice drifted over, sounding entirely too loud, entirely too close.

 

Izuku couldn't answer. He opened his eyes, and the world fractured.

 

The biological dam broke. Deep within his retinas, the genetic code of a prehistoric apex predator snapped into place. The three cones that had defined his vision were violently, instantaneously joined by thirteen others. His eyes, physically altering in real-time, shifted. The smooth, solid green of his irises fractured into thousands of microscopic, multifaceted hexagonal planes.

 

Sixteen color-receptive cones activated simultaneously.

 

The three-cone world died, and a terrifying, incomprehensible universe flooded into Izuku Midoriya's brain.

 

He didn't just see the classroom. He saw the ultraviolet light from the sun outside violently crashing through the windowpanes, painting the walls in glowing, violent streaks of invisible purple. He saw the thermal heat radiating off the bodies of the children around him—vivid, undulating auras of crimson, orange, and blinding white heat rising from their skin. He saw the polarized light bouncing off the shiny linoleum floor, cutting through the air like physical lasers.

 

Colors that had no name in the human language assaulted him. There were colors that shrieked, colors that felt like ice, colors that vibrated with a sickening, dizzying frequency. He looked at the teacher’s desk and saw the stress fractures deep within the wood, glowing in a sickly, pale hue that indicated structural weakness. He looked at the air itself and saw the microscopic dust motes floating on thermal currents, each speck glowing like a miniature star.

 

It was too much. It was a billion times too much. His infant brain, designed to process a simple spectrum, was suddenly hooked up to a sensory input the size of the galaxy.

 

Izuku screamed.

 

It wasn't a cry of a child who had scraped his knee. It was a raw, visceral shriek of absolute agony and sheer terror. He collapsed out of his tiny plastic chair, hitting the linoleum floor, his hands clamped desperately over his eyes.

 

"Midoriya!" The teacher, a kind-faced woman with a minor telekinetic Quirk, rushed forward, her chair scraping loudly against the floor. To Izuku, the sound of the chair was accompanied by a blinding flash of acoustic-visual synesthesia.

 

"No! Stop! Make it dark! Make it dark!" Izuku shrieked, curling into a tight, trembling ball. Even with his eyes squeezed shut, and his hands over his face, he could see. He could see the infrared heat of his own hands. He could see the blood pulsing in his capillaries. The light was piercing right through his eyelids.

 

The classroom descended into chaos. Children began to cry. The teacher dropped to her knees beside Izuku, reaching out to touch his shoulder. Through his fingers, Izuku saw her hand approaching. It wasn't a hand; it was a blazing mass of thermal energy, her muscles twitching beneath the skin, the tendons shifting in bright, neon-blue strings of tension.

 

"Izuku, honey, what is it? Is it your head?" the teacher panicked, her voice trembling.

 

Katsuki had stood up, his red crayon snapping in his grip. He stared down at the writhing boy, his young brow furrowed in a mixture of confusion and irritation. He didn't understand. Deku was always crying, but never like this. Deku was acting like he was dying.

 

"Hey! Deku! Quit screaming!" Katsuki yelled, stepping closer.

 

"Katsuki, stay back!" the teacher warned, but the four-year-old ignored her. He marched right up to Izuku. He didn't like it when things didn't make sense. He didn't like it when his lackey was acting broken.

 

"I said shut up!" Katsuki demanded. To emphasize his point, and perhaps thinking he could shock Izuku out of his hysterics, Katsuki slammed his palms together.

 

POP-CRACK!

 

A small, miniature explosion of nitroglycerin ignited between Katsuki's palms. To a normal human, it was a bright spark, a small flashbang on the scale of a firecracker.

 

To Izuku Midoriya, whose eyes had just become the most sensitive, complex visual organs on the planet, it was a supernova.

 

The flash of light, combined with the sudden burst of extreme thermal heat and ultraviolet radiation off the chemical explosion, pierced through Izuku's fingers and eyelids. It struck his retinas like a physical blade. The sensory overload reached a critical mass, short-circuiting his higher reasoning and plunging him directly into the deepest, most primal recesses of his brain stem.

 

Fight or flight.

 

Izuku couldn't fly. So, the apex predator within his newly rewritten DNA chose to fight.

 

Time seemed to slow to an absolute crawl for Izuku. Through the agonizing, blinding light of Katsuki's spark, Izuku's newly modified vision noticed something else. It noticed the exact angle of Katsuki's stance. It noticed the thermal heat in Katsuki's arms. It saw the empty space between them.

 

And deep within Izuku's right arm, something shifted.

 

Beneath the soft, pudgy skin of the four-year-old, his skeletal and muscular structure had been quietly rearranging itself for months. The bones in his forearm had thickened, becoming dense as titanium. The muscles had coiled, twisting into a complex biological spring. And at the crook of his elbow, a hardened, saddle-shaped mechanism of calcified tissue had formed, acting as a latch.

 

As the primal panic took over, Izuku's arm snapped back. The biological latch in his elbow clicked into place, locking the muscles into a state of extreme, agonizing tension.

 

Katsuki saw Izuku stop screaming. He saw Deku look up.

 

Katsuki froze. He would never, for the rest of his life, forget the eyes that looked at him in that moment. They weren't Deku's eyes. They were wide, unblinking, and entirely alien. The irises were a shifting, swirling kaleidoscope of metallic greens, blues, and purples, divided into three distinct sections by dark horizontal bands. They were the eyes of something ancient, something that lived in the crushing depths of the ocean and knew nothing but violence.

 

"Deku...?" Katsuki whispered, the spark dying in his hands.

 

Izuku didn't aim for Katsuki. Even in his blind, feral panic, some subconscious part of the boy refused to hurt his friend. Instead, Izuku's gaze locked onto the solid concrete and plaster wall just to the left of Katsuki's head. His hyper-vision instantly calculated the distance, the density of the air, and the microscopic stress-faults in the plaster.

 

The biological latch in Izuku's elbow disengaged.

 

What happened next defied the physics of a normal human body. Izuku's arm uncoiled. It did not swing; it released. The strike was so phenomenally fast that the human eye could not track it. The fist moved at speeds exceeding a 22-caliber bullet.

 

But it wasn't the fist itself that was the true danger. It was the physics of what happens when something moves that fast through a fluid medium, even one as thin as air.

 

As Izuku's small fist tore through the atmosphere, the pressure in front of his knuckles skyrocketed, while the pressure immediately behind his fist dropped to a near-vacuum. The sudden, extreme drop in pressure caused the moisture in the classroom air to instantly boil at room temperature. A localized bubble of vaporized water formed around his fist—a cavitation bubble.

 

Izuku's fist didn't even touch the wall. It stopped an inch short.

 

But as his fist decelerated, the vacuum bubble collapsed in on itself. When a cavitation bubble collapses, the surrounding fluid rushes in to fill the void at supersonic speeds. The resulting collision of molecules generates an intense, localized shockwave, a deafening thunderclap, and a momentary flash of light caused by extreme heat—sonoluminescence. For a fraction of a millisecond, the air directly in front of Izuku's fist reached temperatures nearing the surface of the sun.

 

BOOOOOOOOOOM!

 

The sound was not an explosion. It was the apocalyptic crack of a whip wielded by a god.

 

A blinding flash of blue-white light illuminated the preschool. The shockwave erupted from Izuku's fist. It hit the concrete wall with the force of an artillery shell.

 

The wall simply ceased to exist in that specific spot. A crater, three feet wide and a foot deep, was instantly pulverized into fine, white dust. The shockwave continued outward, blasting through the classroom. The thick, reinforced glass of the exterior windows shattered simultaneously, blowing outward into the playground in a hail of diamond-like shrapnel. Desks flipped over. Papers, crayons, and toys were caught in the miniature hurricane, swirling through the air.

 

Katsuki, standing only two feet away from the epicentre of the strike, was blown completely off his feet. He flew backward, hitting a soft play-mat, entirely unharmed but paralyzed by a shock so profound his brain simply stopped processing thought.

 

The thunderous echo faded, replaced by the sound of raining glass and the panicked shrieking of the car alarms outside.

 

In the center of the devastation, the dust slowly began to settle.

 

Izuku remained on his knees. The feral, predatory light in his multifaceted eyes slowly dimmed, replaced by the terrified, overwhelmed tears of a four-year-old boy. He looked down at his right arm.

 

The flesh was bruised a deep, sickly purple. But worse was the angle. The recoil of unleashing such a devastating physical force had been too much for his small, underdeveloped skeletal structure, despite the mutations. His arm hung at a grotesque, unnatural angle. The bones in his forearm were shattered.

 

The pain finally caught up to the sensory overload.

 

Izuku looked at his broken arm, looked at the crater in the wall, looked at Katsuki, and began to wail.

 

The preschool teacher, covered in plaster dust and bleeding from a small scratch on her cheek, stared at the weeping, green-haired boy in absolute, unadulterated horror.

 

Inko Midoriya received the phone call ten minutes later. By the time she arrived at the hospital, her son had been declared one of the most dangerous Quirk prodigies the city had seen in a decade.

 

 

 

The hospital room was kept in complete, pitch-black darkness.

 

Even the small LED lights on the heart monitor had been covered with thick black electrical tape at the frantic behest of the doctors. Any light, even the smallest pinprick, caused the patient’s heart rate to skyrocket into dangerous, panic-inducing levels.

 

Inko Midoriya sat in a chair beside the hospital bed. She was trembling, her hands clamped over her mouth to muffle her sobs. Every few seconds, she would reach out in the darkness, letting her fingers brush against the cold, hard cast that encased her son's right arm from the shoulder down to the fingertips.

 

The door to the private room opened with a soft click. The light from the hallway was immediately blocked by a heavy curtain, allowing Dr. Tsubasa, a leading Quirk specialist, to slip into the room without bringing the agonizing light with him.

 

"Mrs. Midoriya?" the doctor whispered softly in the gloom.

 

"Is he... is he going to be okay?" Inko asked, her voice cracking. "They gave him so much medicine. He won't wake up."

 

"The sedatives are necessary, Mrs. Midoriya," Dr. Tsubasa said gently, pulling up a stool near her. "His brain is currently undergoing a massive rewiring process. If he were awake right now, the pain of his own senses would drive him into shock. We need to keep him under until his cerebral cortex can adapt to the new information."

 

"Information?" Inko sobbed quietly. "I don't understand. The police said... they said he blew up the school. They said he had a villain's quirk."

 

"The police are fools who don't understand biology," Dr. Tsubasa said firmly, a hint of professional awe bleeding into his tone. "I have reviewed his bloodwork, his genetic markers, and his X-rays. Mrs. Midoriya... your son does not have a villain's quirk. He has something extraordinary. I have been studying Quirk genetics for thirty years, and I have never seen a mutation quite this perfectly engineered."

 

Dr. Tsubasa turned on a small tablet, turning the brightness down to the absolute lowest setting before showing it to Inko. It was an X-ray, but not of a toe-joint. It was an X-ray of Izuku's right arm and his skull.

 

"This is not a simple emitter Quirk like your husband's fire breath, nor is it a simple telekinetic pull like yours," the doctor explained, pointing to the screen. "Your son has manifested a profound Mutant-type Quirk, with terrifying Emitter-like secondary effects. I've taken the liberty of registering it under a provisional name. Stomatopod."

 

Inko blinked tears away in the dim light. "Stomatopod? What does that mean?"

 

"It is the scientific classification for the Mantis Shrimp," Dr. Tsubasa said. "It is a marine crustacean, Mrs. Midoriya. It is widely considered to possess the most complex eyes in the animal kingdom, and the fastest, most powerful strike of any living creature on Earth."

 

Inko stared at the X-ray. "A shrimp? But he... he broke a concrete wall."

 

"Indeed. Look at the bone structure of his arm," the doctor traced a finger along the glowing white bones of the X-ray. "Notice the density. His bones are not like human bones anymore. They are laced with a biological equivalent of carbon nanotubes and chitin. And here, at the elbow. Do you see this latch-like formation?"

 

Inko nodded slowly.

 

"That is a spring-loaded biological mechanism," Tsubasa said, his voice hushed with reverence. "When Izuku pulls his arm back, his muscles lock into that latch. Extreme kinetic energy builds up. When the latch releases, his arm moves so incredibly fast that it literally boils the water in the air, creating a vacuum bubble. When that bubble collapses, it unleashes a shockwave and heat. That is what destroyed the wall. It wasn't an explosion from his hand; he literally punched the air so hard the physics of the atmosphere broke."

 

Inko felt sick. "He broke his arm."

 

"Yes," the doctor sighed. "Because his Quirk is a powerhouse. His muscular and skeletal enhancements have not finished catching up to the sheer destructive force his body can generate. He fired a cannon out of a wooden boat, so to speak. The recoil shattered his ulna and radius. He will need physical therapy, and he cannot be allowed to strike with maximum force again until his body fully matures, or he risks permanently losing the arm."

 

"Oh, my baby," Inko wept, gently touching Izuku's cheek in the dark.

 

"But that is only half of the Quirk," Dr. Tsubasa continued, his tone shifting to something more cautious. "The physical mutation of his arms is secondary to his eyes. Mrs. Midoriya, why do you think he was screaming about the light?"

 

"His eyes were glowing," Inko recalled from the police report. "They said his eyes changed."

 

"Human beings have three color-receptive cones. We see red, blue, and green," Tsubasa explained. "Izuku's retinas have mutated to possess sixteen. He is currently seeing the world in a spectrum we cannot even begin to imagine. He sees ultraviolet light. He sees polarized light. We believe he can see thermal heat signatures, and possibly even the electrical impulses in muscle tissue."

 

Inko gasped. "Sixteen? But... how can he stand it?"

 

"Right now, he can't," Tsubasa admitted. "It is total sensory overload. Imagine having someone scream through a megaphone directly into your ear, constantly, every waking second of your life. That is what his eyes are doing to his brain. Everything is too bright, too colorful, too detailed. We are currently manufacturing a specialized pair of visual dampeners—goggles—that will filter out the extreme ends of the spectrum, blocking the UV and polarizing the light to a manageable level. He will have to wear them at all times."

 

"Will he ever have a normal life?" Inko asked, her voice trembling with the weight of a mother’s fear.

 

Dr. Tsubasa looked at the sleeping boy. Even in the darkness, the faint, shimmering iridescence of Izuku's multifaceted eyes could be seen through his slightly parted eyelids.

 

"Normal? No," Dr. Tsubasa said honestly. "He has the optics of an apex predator and the striking force of a biological bomb. He has hidden gills developing along his ribcage that will require a highly humidified environment, and his dietary needs for calcium and protein will skyrocket to maintain that exoskeleton-bone density."

 

The doctor stood up, placing a reassuring hand on Inko's shoulder.

 

"He will not be normal, Mrs. Midoriya. But in this world of Quirks, 'normal' is a concept of the past. If he learns to control this power... if he can harness the mind required to process that visual information... your son could become a Hero unlike anything this world has ever seen."

 

 

 

It took three weeks for the hospital to fabricate the goggles, and for the sedatives to be fully weaned from Izuku's system.

 

The day he was allowed to leave the hospital, Inko brought the specialized eyewear into the dim room. They were bulky, resembling a cross between tactical military goggles and heavily tinted aviator sunglasses. The frames were a matte black, lined with soft neoprene to protect the skin around his eyes, and the lenses were a thick, polarized, iridescent amber that completely hid his eyes from the outside world.

 

"Here, sweetheart," Inko whispered, sitting on the edge of the bed. Izuku was curled up, his eyes squeezed tightly shut, his broken arm resting in a heavy sling against his chest. "The doctor said these will help."

 

Izuku whimpered. "It hurts, Mom. The colors are too loud."

 

"I know, baby. I know. Let me put these on you. Keep your eyes closed."

 

Inko carefully slid the strap over his messy green curls, settling the heavy goggles over his eyes. She adjusted the seal, ensuring no stray light could leak in from the sides.

 

"Okay," Inko said softly. "Open them. Slowly."

 

Izuku took a shaky breath. He braced himself for the agonizing blast of the unseeable spectrum. He slowly peeled his eyelids open.

 

He gasped.

 

The pain was gone. The blinding, screaming chaos of the ultraviolet rays and the overwhelming neon glow of thermal heat had been muted. The world was still vastly different from the three-cone world he had known a month ago, but it was no longer a weapon used against him.

 

Through the polarized, layered amber lenses, the world looked... beautiful.

 

He could still see the heat radiating off his mother, a soft, comforting aura of warm orange and yellow that pulsed with the steady rhythm of her heartbeat. He could see the intricate, crystalline structure of the hospital windowpane. He looked down at his own cast, seeing the exact stress lines where the plaster was thickest.

 

The sixteen cones in his eyes were still firing, but the goggles acted as a funnel, organizing the chaotic influx of data into a coherent, manageable overlay.

 

"I can see, Mom," Izuku whispered, reaching up with his good hand to touch the rim of the goggles. "It doesn't hurt."

 

Inko broke down in tears of relief, pulling him into a gentle hug, mindful of his broken arm. As she held him, Izuku looked over her shoulder at the muted television screen in the corner of the room. It was playing a news broadcast.

 

A villain made of living sludge was tearing through a shopping district. The hero Kamui Woods was attempting to restrain the villain, swinging from the buildings.

 

In the past, Izuku would have just watched the hero and cheered. He would have looked at Kamui’s cool wooden arms and thought about how strong he was.

 

But now... now, Izuku didn't just watch the fight. He analyzed it.

 

Through the screen, his enhanced, multifaceted eyes caught details that the cameraman didn't even know he was filming. Izuku could see the structural stress in Kamui Woods' timber. He could see where the wood was splintering under the villain's pressure, glowing with a faint, microscopic aura of kinetic friction. He looked at the sludge villain and realized, by analyzing the thermal patterns of the fluid, exactly where the villain's solid, physical core was hidden within the liquid mass.

 

If Kamui Woods aims for the upper left quadrant, he'll hit the core, Izuku thought, his mind racing at a million miles an hour. The sludge is colder there. That's the weak point.

 

On the screen, Kamui Woods struck the wrong side. The villain retaliated, blasting the hero back.

 

Izuku’s breath hitched. He saw the world entirely differently now. He didn't just see Heroes and Villains. He saw physics, biology, thermal dynamics, and structural integrity. He saw the threads that held the world together, and the exact points where those threads could be cut.

 

"Mom?" Izuku said, his voice suddenly very clear, the panic of the past month entirely gone.

 

"Yes, Izuku?" Inko sniffled, pulling back to look at his goggled face.

 

"When we get home... can I have a new notebook?"

 

Inko smiled, wiping her tears. "Of course, sweetheart. Whatever you want. What are you going to draw?"

 

"Not drawing," Izuku said, staring intently at the television, his mind already categorizing the strengths and fatal flaws of the heroes on screen. "I'm going to write things down. I need to remember what I'm seeing. Because... because I'm going to be a Hero, Mom. I'm going to be the best."

 

It wasn't a child's idle dream anymore. It was a statement of terrifying fact.

 

 

 

Returning to the outside world was an adjustment.

 

Izuku's bedroom had to be modified. A heavy-duty humidifier was installed to keep the air moist, easing the dry, itching sensation of the dormant gills that had formed along his ribs. His diet was altered, loaded with calcium supplements and protein to feed the insatiable demand of his rapidly densifying skeletal structure. He had to undergo physical therapy for his right arm, learning how to consciously suppress the biological latch in his elbows so he didn't accidentally fire off a sonic boom every time he stretched.

 

But the biggest adjustment was the social one.

 

When Izuku returned to the playground two months later, his cast finally removed and replaced with a compressive brace, everything had changed.

 

The other children stared at him. They whispered behind their hands. The boy who had been Quirkless, the boy who cried all the time, had returned as a monster. Rumors had spread like wildfire among the parents and trickled down to the children. He blew up the school. He's got mutant eyes. He wears those creepy goggles because if you look into his eyes, you go blind.

 

Izuku stood at the edge of the sandbox, his hands gripping the straps of his bright yellow backpack. He felt the weight of their stares. Through his goggles, he could literally see the cold, pale blue hues of fear radiating off the other kids. They were terrified of him.

 

He gripped the straps tighter, looking down at his bright red shoes. Maybe he should just go home.

 

"Hey. Goggles."

 

Izuku looked up.

 

Katsuki Bakugo stood a few feet away. The blonde boy had his hands shoved deep into his pockets, his chin jutting out in a mixture of defiance and complex childhood aggression. He didn't look scared. To Izuku's hyper-vision, Katsuki's thermal signature was a blazing, angry red, pulsing with adrenaline and something else... a fierce, burning competitive drive.

 

Katsuki marched forward, stopping just inches from Izuku. He glared at the dark, reflective lenses of Izuku's goggles.

 

"So," Katsuki said, his voice low. "You got a Quirk."

 

"Y-yeah, Kacchan," Izuku stuttered, his old habits dying hard.

 

"They say you blew up the wall," Katsuki sneered, though there was a slight tremor in his voice, betraying the memory of the deafening thunderclap that had knocked him off his feet. "They say your punch is stronger than my explosions."

 

Izuku hesitated. He looked at Katsuki. He saw the microscopic tension in Katsuki's jaw muscles. He saw the heat building in Katsuki's palms as the boy subconsciously prepared to ignite his sweat. In the past, Izuku would have cowered. He would have apologized for something he didn't even do.

 

But Izuku wasn't blind anymore. He saw the truth. Kacchan wasn't just being mean. Kacchan was threatened.

 

"The doctor said my bones are different," Izuku said quietly, his voice steadier than he expected. "He said if I punch like that again right now, my arm will fall off."

 

Katsuki scoffed, puffing out his chest. "So you're a glass cannon. A one-hit wonder who breaks his own toys." Katsuki leaned in close, sparks popping from his palms, reflecting vividly off Izuku's lenses. "Listen to me, Deku. I don't care if you have a freaky shrimp punch or weird bug eyes under those glasses. I'm still going to be Number One. You're still beneath me."

 

It was an insult, but to Izuku, it sounded like a challenge. It sounded like an acknowledgment. Katsuki wasn't dismissing him as Quirkless. He was acknowledging Izuku as a player on the board. A rival.

 

Izuku didn't flinch away from the sparks. He stood his ground. Beneath the dark lenses, his multifaceted eyes locked onto the exact center of Katsuki's chest, watching the heart rhythm pulse in vibrant hues of ultraviolet.

 

"I'm going to learn how to use it, Kacchan," Izuku said, his voice calm, ringing with an unnerving certainty. "I'm going to train. I'm going to make my arms strong enough to take the recoil. And I'm going to U.A. just like you."

 

Katsuki stared at the impassive, insectoid gaze of the goggles. For a moment, the heat signature in Katsuki's chest flared wildly, a spike of genuine, unadulterated surprise. Then, a sharp, feral grin spread across the explosive boy's face.

 

"You better, Deku," Katsuki growled, turning on his heel and marching back toward the jungle gym. "Because when we get there, I'm going to crush you, shrimp eyes and all."

 

Izuku watched him go. He didn't feel the sting of the nickname. He didn't feel the familiar, crushing weight of inadequacy.

 

He reached into his backpack and pulled out a brand-new, freshly bound notebook. Across the front cover, written in messy, four-year-old handwriting, were the words: Hero Analysis for the Future: Volume 1.

 

Izuku opened it to the first blank page. He looked around the playground. He looked at the kids playing, the birds flying overhead, the subtle shifts in the wind carrying invisible trails of pollen and heat. The world was a massive, infinite puzzle of physics, light, and kinetic energy, and Izuku Midoriya had been given the master key to solve it.

 

He clicked his pen.

 

He had ten years before U.A. High School. Ten years to build his body into a weapon capable of housing a Stomatopod. Ten years to fill his notebooks with the secrets of a million unseen colors.

 

Izuku smiled, a small, confident curve of his lips, and began to write.

 

The world didn't know it yet, but the apex predator was preparing for the hunt.

 

 

The human body is an incredibly adaptable machine, but it is not designed to wield the power of a naval artillery cannon. For Izuku Midoriya to simply survive the manifestation of his own genetics, his entire life had to be reconstructed from the ground up.

 

Ten years had passed since the incident at Aldera Preschool. Ten years of rigorous, grueling, and entirely necessary physical conditioning.

 

At fourteen years old, Izuku Midoriya did not look like the other boys in his middle school. When he looked in the mirror every morning, standing in the heavily humidified mist of his bathroom, he saw the results of a decade of survival. He was not overly tall, but his physique was a testament to biological engineering and sheer, stubborn willpower.

 

His torso was corded with dense, compact muscle, but the true mutation lay in his back and his arms. His latissimus dorsi and trapezius muscles were abnormally thick, creating a wide, V-shaped wedge designed to anchor the massive kinetic forces generated by his strikes. His arms, specifically from the elbows down, were heavily scarred from years of micro-fractures. His forearms were thick, layered with a sub-dermal plating of chitinous bone-weave that felt like solid steel to the touch. Along his ribcage, hidden just beneath the surface of his skin, three subtle slits opened and closed with each breath—dormant gills that required him to sleep in a room so humid it was practically raining.

 

And then, there were the goggles.

 

Izuku reached onto the bathroom counter and picked up his specialized eyewear. They had been upgraded over the years as he grew. The current model resembled a pair of sleek, high-tech tactical visors, framed in matte black impact-resistant polymer. The lenses were a deep, iridescent amber, highly polarized and heavily tinted.

 

He slipped them on, the soft neoprene sealing snugly against his cheekbones and brow. Instantly, the blinding, chaotic noise of the morning sun filtering through the bathroom window was silenced.

 

The raw, unfiltered spectrum of his sixteen-cone vision was compressed, filtered, and translated into a HUD of his own mind's making. He could still see the thermal heat radiating off the hot water in the sink—a swirling vortex of bright orange and yellow against the cool blue of the porcelain. He could still see the microscopic stress fractures in the bathroom mirror, glowing with faint ultraviolet lines. But it was manageable. It was a tool, rather than a torture device.

 

Izuku sighed, rolling his right shoulder. A loud, heavy crack echoed in the small room as the dense, calcified latch in his elbow joint popped into place and then released.

 

He was ready for the day.

 

 

 

Aldera Junior High was a crucible of raging hormones, developing Quirks, and the suffocating pressure of impending high school applications.

 

Izuku sat quietly at his desk near the back of the classroom, his head bowed over a worn, heavily annotated notebook. The title on the cover read: Hero Analysis for the Future: Vol. 13. He was currently sketching a diagram of the Pro Hero Backdraft, specifically analyzing the water pressure required to combat Class-A chemical fires, cross-referencing it with the thermal output he had personally observed during a villain fight three days prior.

 

The classroom was loud. To Izuku, it was also visually loud. Through his amber lenses, he could see the thermal signatures of his thirty classmates. Most were a relaxed, steady yellow.

 

Except for one.

 

Two rows ahead and to the left, Katsuki Bakugo’s thermal signature was practically vibrating. It was an intense, aggressive crimson, hottest around the boy's forearms and palms where his nitroglycerin sweat glands were most active.

 

"Since you're all third years, it's time for you to think seriously about your future," their homeroom teacher announced, standing at the front of the class with a stack of papers. "I'll pass out handouts for your future plans now, but... you're all pretty much planning to go into the hero course, right?"

 

The teacher threw the stack of papers into the air. Instantly, the classroom erupted. Students activated their Quirks in a chaotic display of minor superpowers—elongated fingers, floating objects, small flashes of light.

 

Izuku didn't move. He simply kept writing, his pen moving with mechanical precision.

 

"Yes, yes, you all have wonderful Quirks," the teacher sighed, "but using your powers in school is against the rules!"

 

"Sensei! Don't lump me in with these losers!"

 

Katsuki’s voice cut through the din like a chainsaw. He was leaning back in his chair, his feet kicked up on his desk, a feral, arrogant smirk plastered across his face. "As if I had anything in common with these weaklings. My Quirk is in a completely different league."

 

The class immediately turned on him, shouting insults, but Katsuki just laughed, tiny explosions popping off his palms. "Shut up, extras! You should be begging me to remember you when I'm rich and famous!"

 

"Ah, Bakugo," the teacher said, looking at his clipboard. "You're aiming for U.A. High School, aren't you?"

 

A hushed, reverent silence fell over the room. U.A. High School. The pinnacle of hero academia. The acceptance rate was less than point-two percent.

 

"That's exactly why it's the only place for me," Katsuki declared, leaping onto his desk. "I aced all the mock tests! I'm the only one at this school who could possibly get into U.A. I'll surpass All Might and become the top hero, and my name will be inscribed on the list of top earners!"

 

"Oh, right," the teacher added, pushing his glasses up his nose. "Midoriya wants to go to U.A. too, right?"

 

The silence that followed this statement was vastly different from the one that preceded it.

 

Ten years ago, the class would have burst into hysterical laughter. They would have pointed and jeered at the Quirkless boy dreaming of the impossible. But they were not four years old anymore. They all remembered the rumors of the crater in the preschool wall. They all saw the heavy, chitinous plating pushing against the fabric of Izuku’s school uniform. They all saw the unsettling, unreadable amber lenses of his goggles.

 

They didn't laugh. They murmured.

 

“Midoriya? Seriously?”

“I mean... his Quirk is crazy strong, right?”

“Yeah, but it’s a mutant type. He looks like a cyborg. Can someone like that really be a hero?”

“I heard he can break a car in half.”

 

Katsuki’s smirk vanished. The crimson heat signature in his chest flared into a blinding white. He slowly turned his head, his red eyes locking onto Izuku’s goggles.

 

Izuku stopped writing. He looked up, his expression completely neutral behind his visor.

 

In a flash of movement, Katsuki lunged over the desks. He slammed his right hand down flat onto Izuku’s notebook.

 

BOOM!

 

A localized explosion of nitroglycerin detonated, scorching the wooden desk and instantly carbonizing the edges of Izuku's notebook. Smoke billowed upward, smelling of burnt sugar and ozone.

 

Izuku did not flinch. He didn't blink. Through his lenses, he had seen the chemical reaction building in Katsuki's sweat pores a full second before the detonation. He had watched the microscopic spark ignite, mapping the blast radius before the sound wave even reached his ears.

 

"Listen to me, Deku," Katsuki growled, his face inches from Izuku’s goggles. Smoke curled from his palms. "You might have some freaky, bone-breaking parlor trick, but you're still a tactical idiot. You think you can stand in the same arena as me? You think your bug-eyes give you the right to look down on me?"

 

Izuku slowly reached out. He gripped the charred edges of his notebook and calmly pulled it out from under Katsuki's smoking hand.

 

"I don't look down on you, Kacchan," Izuku said quietly. His voice was steady, resonant with an underlying bass that hinted at the sheer density of his chest cavity. "Your Quirk is incredibly versatile. Your reaction times are in the ninety-ninth percentile. But U.A. doesn't have a quota. Two people from the same school can get in."

 

"I am going to be the only one from this garbage school to get in!" Katsuki snarled, slamming his fist onto the desk again, fracturing the wood. "I am going to be the undisputed first-place draft pick! If you get in my way during the exam, I’ll blow those stupid glasses right off your face!"

 

Katsuki spun on his heel and marched back to his desk, kicking a chair out of his way. The rest of the class held their breath, waiting for Izuku's reaction.

 

Izuku simply dusted the ash off his notebook, opened it to a fresh page, and continued writing.

 

Bakugo Katsuki. Thermal volatility increased by 15% since last observation. Heart rate spiked to 140 BPM. Emotional instability linked to perceived threat to dominance.

 

Izuku sighed internally. Katsuki was exhausting, but he was predictable. The real challenge of the day was yet to come.

 

 

 

The walk home from school was Izuku’s favorite part of the day. It was his chance to practice his sensory filtering.

 

He walked under a massive, concrete railway overpass, the shadow of the bridge providing a cooling relief from the afternoon sun. He adjusted his goggles, switching his active focus from the thermal spectrum to the polarized light spectrum. Instantly, the harsh glare bouncing off the damp concrete vanished, revealing the intricate textures of the urban environment.

 

He could see the microscopic colonies of moss growing in the dampest corners of the underpass. He could see the structural stress lines running through the concrete pillars, holding up tons of steel and asphalt above him.

 

It was peaceful.

 

Gurgle. Schlorp.

 

Izuku stopped.

 

His ears, though completely human, caught the wet, heavy sound. But it wasn't his ears that alerted him to the danger. It was his eyes.

 

Behind him, emerging from a heavy cast-iron manhole cover, a massive thermal anomaly was rising. Izuku spun around.

 

A towering mass of dark green sludge was pulling itself out of the sewer. It was easily seven feet tall, undulating and shifting, smelling strongly of sewage and rotting garbage. Two massive, bulbous eyes floated near the top of the fluid mass, alongside a jagged maw of what looked like human teeth.

 

"A medium-sized invisibility cloak..." the Sludge Villain rasped, its voice bubbling and wet. "Perfect. You look like a sturdy kid. That armor on your arms will hold up nicely while I take over."

 

The villain lunged, a massive wave of thick, suffocating fluid crashing down toward Izuku.

 

Ten years of martial arts conditioning kicked in. Izuku didn't panic. He didn't scream. Time seemed to dilate as his mind shifted into a state of hyper-analysis.

 

Through his amber lenses, Izuku observed the fluid dynamics of the villain. The sludge was not a uniform density. It was a non-Newtonian fluid, thick and viscous on the outside to maintain its shape, but the thermal signature revealed a much thinner, colder liquid center where the villain's actual consciousness resided.

 

If he surrounds me, I'll suffocate, Izuku calculated in a fraction of a second. I need to displace the mass.

 

Izuku planted his feet wide, his customized red sneakers gripping the concrete. He lowered his center of gravity. He brought his right arm back, pulling his elbow in tight against his ribs.

 

Deep within his arm, the biological mechanism engaged.

 

CLICK.

 

It was a sound like a heavy deadbolt slamming shut inside a steel vault. The dense, coiled muscles in his forearm locked into the saddle-shaped calcified latch in his elbow joint. The sheer kinetic tension building in his arm was immense; his bicep bulged, the chitinous plating beneath his skin straining against the fabric of his uniform.

 

The Sludge Villain loomed over him, laughing. "Don't fight it, kid! It'll only hurt for about forty-five seconds!"

 

Izuku looked up. His eyes locked onto the exact center of the sludge mass.

 

He didn't need to punch the villain. He just needed to punch the air.

 

Ten percent output, Izuku commanded himself.

 

He disengaged the latch.

 

His right arm blurred. It did not simply move forward; it deleted the space between his hip and the air in front of his chest. The speed of the strike was so violent that the air molecules could not move out of the way fast enough. The pressure in front of his knuckles spiked to immense levels, while the pressure behind his fist plummeted.

 

A tiny, shimmering bubble of vaporized air formed at the apex of his punch.

 

And then, his fist stopped. The bubble collapsed.

 

CRACK-BOOM!

 

Even at a mere ten percent of his maximum biological output, the cavitation strike was devastating. A shockwave of highly compressed air erupted from his knuckles, accompanied by a deafening bang that echoed under the overpass like a cannon shot. A brief, blinding flash of blue-white light—sonoluminescence—illuminated the shadows.

 

The Sludge Villain never even touched him.

 

The shockwave slammed into the viscous fluid. The sheer concussive force instantly disrupted the surface tension of the villain's body. The sludge was blown backward, violently scattered across the walls and ceiling of the underpass in a massive, messy splatter.

 

"GAAAAAH!" the villain shrieked, its eyes spinning dizzily as its main mass was forcefully separated from its appendages. The villain hit the far wall and collapsed into a disorganized puddle of groaning muck.

 

Izuku stood perfectly still, his right arm extended. Slowly, carefully, he pulled his arm back, rubbing his heavily calloused knuckles. Thin wisps of steam curled off his skin from the momentary flash-boil of the air.

 

"Target neutralized. Minimal collateral damage," Izuku muttered to himself, letting out a breath he didn't realize he was holding. He looked at his arm. It didn't hurt. Ten years of drinking bone-marrow broth and striking sandbags filled with iron shavings had paid off. A ten-percent strike no longer shattered his ulna.

 

CLANG!

 

The manhole cover a few yards away suddenly flew into the air, spinning like a coin before crashing onto the pavement.

 

A massive, impossibly muscular figure erupted from the sewer, landing with a heavy, earth-shaking thud. He was dressed in a simple white t-shirt and cargo pants, but his sheer size and the golden, twin-tufted hair on his head were unmistakable.

 

"HAVE NO FEAR!" the man bellowed, his voice booming with a charismatic, overwhelming authority that seemed to vibrate the very air. "FOR I AM—!"

 

All Might froze.

 

The Number One Hero, the Symbol of Peace, stood in a heroic, wide-stanced pose, his fist drawn back, ready to obliterate the villain he had been chasing through the sewers for the last twenty minutes.

 

Instead, he saw a dark, empty underpass, heavily splattered with foul-smelling green sludge. In the center of the mess stood a teenage boy in a black school uniform, wearing highly reflective amber goggles, gently rolling his right shoulder.

 

All Might blinked, looking down at the groaning puddle of sludge. Then he looked at the boy.

 

"Ah," All Might said, his booming voice dropping an octave in sheer confusion. "It appears... you have already handled the situation, young man."

 

Izuku Midoriya, despite his intense training, despite his analytical mind, and despite his terrifying mutation, was still fundamentally a fourteen-year-old fanboy.

 

He froze. His jaw dropped. Through his goggles, he saw the man. But he didn't just see All Might.

 

Izuku’s multifaceted eyes scanned the thermal signature of the Symbol of Peace. And what he saw made his blood run cold.

 

To the naked eye, All Might was a paragon of health and invincibility. But to Izuku, the hero's thermal aura was a horrifying mess. The right side of All Might’s torso glowed with a healthy, blazing golden-yellow heat. But his left side... the left side of his stomach and lower chest was a sickly, dark, cold purple. It was a massive void of thermal energy, a spiderweb of necrotic tissue, severed arteries, and missing organs held together by sheer, unnatural force. The heat was bleeding out of him, fighting a losing battle against a devastating, unseen injury.

 

He's dying, Izuku realized with absolute, horrifying clarity. The Symbol of Peace is literally holding himself together by a thread.

 

"Y-You're..." Izuku stammered, pointing a trembling finger. "You're All Might."

 

"THAT I AM!" All Might laughed heartily, quickly producing two large, empty plastic soda bottles from his pockets. He began moving with blinding speed, scooping the scattered sludge villain into the bottles and capping them tight. "Excellent work, young man! A powerful Quirk you have there! Concussive blast? Shockwave generation?"

 

"I-It's a biological cavitation mechanism," Izuku blurted out, his mind racing. "I can create a localized vacuum bubble by moving my arm at hyper-sonic speeds, and the collapse generates a shockwave. S-Sir, are you okay?"

 

All Might paused, a bottle halfway to his pocket. The hero's massive, shadowed eyes narrowed slightly. "Of course I am! Why do you ask?"

 

Izuku hesitated. He knew he shouldn't pry. He knew he sounded crazy. But his eyes never lied to him.

 

"Your... your left side," Izuku whispered, pointing to the exact spot on All Might's ribs where the dark, cold void lay hidden beneath the white t-shirt. "The thermal signature. It's... it's gone. There's no heat there. Half your respiratory system is missing."

 

All Might's smile vanished. The sheer, overwhelming aura of the Number One Hero suddenly condensed into something sharp, dangerous, and incredibly focused.

 

Before Izuku could blink, All Might moved. The wind blasted Izuku's hair back as the massive hero crossed the distance in a microsecond, his huge hand clamping gently but firmly onto Izuku's shoulder.

 

"Young man," All Might said, his voice no longer booming, but quiet, intense, and deadly serious. "What exactly can you see behind those glasses?"

 

Izuku swallowed hard. "Everything. I see sixteen spectrums of light. I see thermal energy. I see... I see that you are severely injured, sir."

 

All Might stared at the boy. The boy didn't flinch. He didn't look away.

 

Suddenly, a violent cough wracked All Might’s massive frame. A plume of steam erupted from his body.

 

Izuku stumbled back as the steam cleared. The towering, muscular god of a hero was gone. In his place stood a skeletal, emaciated man with sunken cheeks, baggy clothes, and blood trickling from the corner of his mouth.

 

"I suppose," the skeletal man sighed, wiping the blood away with a bony thumb, "there is no hiding from eyes like yours."

 

 

 

They relocated to the roof of a nearby commercial building. It was quiet, isolated, and safe from prying eyes.

 

All Might sat against the railing, his long, thin legs drawn up. He explained everything. He explained the fight five years ago. He explained the villain, the Toxic Chainsaw cover-up, the loss of his stomach, the repeated surgeries, and his agonizing, three-hour daily limit as a hero.

 

Izuku sat silently, his legs crossed, listening intently. The revelation would have shattered the world of any normal teenager. But Izuku’s world was already painted in a million unseen, complex colors. He understood the fragile nature of biology better than anyone. He didn't see All Might as weak; he saw the absolute, terrifying willpower required to force a dying body to stand up and smile.

 

"A Symbol of Peace who saves people with a smile must never be daunted by evil," All Might said softly, looking down at his scarred, skeletal hands. "I smile to show the pressure of heroes, and to trick the fear inside myself. Pro Heroes are always having to risk their lives. Some villains just can't be beaten without rules being broken."

 

All Might looked up at Izuku. The amber goggles reflected the setting sun.

 

"You have a terrifying eye for detail, young man. And a powerful Quirk. What is your name?"

 

"Midoriya. Izuku Midoriya."

 

"Well, Young Midoriya. You possess the strength to defend yourself, and the sight to see the truth of the world. You are aiming for U.A., I presume?"

 

"Yes," Izuku said softly. He looked down at his own heavily scarred forearms. "But... I don't know if I can be a hero like you."

 

All Might raised a skeletal eyebrow. "Oh? You took down a villain with a single strike. That speaks of immense potential."

 

"My Quirk..." Izuku hesitated. He unclasped the strap of his right wrist brace, rolling up his sleeve. He showed All Might the thick, unnatural, chitinous plating that fused his skin to his bones. "It's a mutant type. The doctor called it a Stomatopod. A mantis shrimp. I'm literally built to be an apex predator."

 

Izuku looked up, the amber lenses fixing on All Might. "That shockwave I used? That was ten percent of my power. If I use one hundred percent... I can flash-boil the water in the air to the temperature of the sun for a microsecond. I can blow a hole through a tank. My Quirk isn't made to restrain people, All Might. It's made to kill things. I have the eyes of a monster and the arms of a biological bomb. Can someone with a lethal Quirk... can someone who looks at people and only sees their physical weak points... really be a Symbol of Peace?"

 

All Might was quiet. He looked at the boy. He saw the heavy burden on those young, abnormally muscular shoulders. He saw a boy who possessed the power to devastate, but the heart to hold it back.

 

"Young Midoriya," All Might said, his voice surprisingly gentle. "A Quirk is merely a tool. A scalpel in the hands of a murderer is a weapon. A scalpel in the hands of a surgeon is a salvation. You are not your genetics. You are the choices you make with them. You saw my injury, yet you did not recoil in fear, nor did you try to exploit it. You asked if I was okay. That is the heart of a hero."

 

All Might slowly stood up, gripping the railing. "If you fear your own power, then you must master it. You must build your body and your mind until you are in absolute control of that weapon. A hero does not kill. A hero saves. If you can learn to control that power, to use it to protect rather than destroy, then yes. You can be a hero."

 

Izuku felt a tightness in his chest that had nothing to do with his gills. A tear slipped from his eye, hidden beneath the neoprene seal of his goggles.

 

"Thank you," Izuku whispered.

 

"Now," All Might coughed, patting his pockets. "I must get this sludge fellow to the police—"

 

All Might froze. His hands frantically slapped his cargo pants pockets.

 

They were empty.

 

Izuku’s eyes widened. He stood up, scanning the roof. "Did you drop them?"

 

BOOM!

 

The sound of a massive explosion echoed from the city blocks away, followed instantly by the rising plume of thick, black smoke.

 

Izuku’s head snapped toward the sound. Through his goggles, he didn't just see the smoke. He saw the chemical signature of the fire. It wasn't wood burning. It wasn't gasoline.

 

It was a brilliant, blinding flash of highly concentrated thermal energy, laced with the distinct ultraviolet flare of detonating nitroglycerin.

 

Kacchan.

 

"I dropped the bottles," All Might horrified whisper confirmed it. "When you grabbed my leg to ask about my injury... I must have dropped them."

 

Izuku didn't wait. He didn't think.

 

He bolted.

 

"Young Midoriya, wait!" All Might yelled, trying to summon his muscle form, but coughing violently instead, blood spraying from his lips. He had hit his limit.

 

Izuku was already sprinting across the rooftops. His heavily muscled legs propelled him with terrifying speed, clearing the gaps between the commercial buildings in massive, soaring leaps.

 

He followed the thermal plumes. He followed the explosions.

 

He arrived at Tatooin Shopping District a minute later, dropping from a fire escape into the gathering crowd. The entire street was a war zone. Fires raged across the storefronts. Pro Heroes Death Arms, Kamui Woods, and Mt. Lady were standing at the perimeter, utterly useless.

 

"It's no good!" Death Arms shouted, shielding his face from the heat. "I can't get close! The heat is too intense!"

 

"I need at least a two-lane road to get big!" Mt. Lady groaned.

 

"My wood will just catch fire!" Kamui Woods yelled.

 

Izuku pushed through the crowd, his amber lenses reflecting the raging inferno.

 

In the center of the street, the Sludge Villain had grown massive, feeding on the chaos. And trapped within its suffocating, fluid body, struggling wildly, was Katsuki Bakugo.

 

Katsuki was firing explosions from his palms, desperately trying to blow himself free, but the villain’s non-Newtonian body simply absorbed the concussive force, reforming instantly. Katsuki’s face was half-covered, his red eyes wide with genuine, unadulterated terror.

 

Izuku’s hyper-vision instantly calculated the situation.

 

The heroes are waiting for someone with a suitable Quirk. But Kacchan's oxygen levels are dropping. His thermal signature is dimming. He has less than forty seconds before asphyxiation.

 

Izuku looked at the Sludge Villain. The villain had grown, but its fundamental structure hadn't changed. The true core, the brain, was still hiding within the fluid. But because Katsuki was firing explosions, the fluid was boiling, churning, and hiding the core from normal sight.

 

But Izuku didn't have normal sight.

 

He switched his optical focus. He filtered out the blinding infrared heat of the fires. He filtered out the ultraviolet flash of the explosions. He looked deep into the exact center of the churning sludge, utilizing a spectrum of light that pierced through the viscous fluid like an x-ray.

 

He found it. A small, cold, dense knot of matter located just behind the villain's left eye. The core.

 

Izuku didn't think about his arm. He didn't think about the law against using Quirks in public.

 

He moved.

 

He exploded from the crowd, his red sneakers shattering the asphalt beneath him.

 

"Hey! Kid, stop! You'll die!" Death Arms roared, reaching out, but his hand closed on empty air.

 

Izuku was a blur. He sprinted through the wall of fire, the heat washing over his chitin-plated arms. The Sludge Villain looked down, its massive eyes widening in recognition.

 

"YOU!" the villain roared. "I'LL KILL YOU!"

 

The villain whipped a massive tendril of sludge toward Izuku, as thick as a telephone pole.

 

Izuku didn't dodge. He planted his left foot, dug his heel into the street, and spun. He used the momentum of his spin to pull his right arm back.

 

CLICK.

 

The biological latch in his elbow locked. His bicep strained, the veins bulging against his skin. This wasn't ten percent. This was a hostage situation. This required surgical precision and overwhelming force.

 

Fifty percent output.

 

Izuku launched himself off his right foot, soaring into the air directly toward the villain's central mass. Katsuki's terror-filled eyes locked onto the amber lenses of Izuku's goggles.

 

"DEKU!" Katsuki garbled through the sludge.

 

Izuku raised his left hand, forming a flat, rigid blade. He drove his left hand directly into the sludge, not to hurt it, but to create a pilot hole, a path of least resistance through the dense fluid.

 

Then, he brought his right fist forward.

 

He released the latch.

 

Pistol Strike.

 

The sheer violence of the movement defied human comprehension. Izuku’s fist accelerated so fast that a cone of white vapor instantly materialized around his arm—a macroscopic sonic boom.

 

His fist traveled down the pilot hole created by his left hand, aiming precisely two inches to the left of Katsuki’s trapped face.

 

He didn't hit Katsuki. He didn't even hit the Sludge Villain’s core.

 

He stopped his fist precisely one millimeter short of the villain's internal cold-spot.

 

The cavitation bubble that had formed around his fist, a vacuum devoid of matter, collapsed.

 

KRA-KOOOOOOM!

 

It was as if a lightning bolt had detonated at ground level. A flash of blinding, sonoluminescent blue-white light erupted from the center of the sludge. The heat generated in that microsecond was phenomenal, instantly flash-boiling the surrounding sludge into steam.

 

But the true devastation was the shockwave.

 

The concussive force exploded outward from the epicenter. Because water does not compress, the shockwave rippled through the Sludge Villain's entirely fluid body with zero loss of kinetic energy.

 

The villain literally exploded from the inside out.

 

Tons of foul-smelling liquid were blasted outward in a perfect 360-degree radius, raining down on the burning buildings, instantly dousing the chemical fires. The force of the blast shattered the remaining windows on the street and knocked Death Arms and Kamui Woods clean off their feet.

 

In the center of the blast radius, suspended in the air for a fraction of a second, were Izuku and Katsuki.

 

Izuku grabbed the collar of Katsuki’s uniform with his left hand, twisting his body to take the brunt of their fall. They crashed into the asphalt, rolling several times before coming to a halt.

 

Silence descended upon the Tatooin Shopping District, broken only by the sound of falling water and the hissing of extinguished fires.

 

Izuku lay on his back, staring up at the smoke-filled sky through his goggles. His breath came in ragged gasps. The dormant gills on his ribs fluttered frantically, desperate for oxygen. He slowly lifted his right arm.

 

It was trembling violently. The skin was bright red, scorched by the radiant heat of his own sonoluminescent flash. He could feel the deep, throbbing ache of micro-fractures spider-webbing along his ulna. Fifty percent was his absolute limit before catastrophic bone failure.

 

Katsuki pushed himself up onto his hands and knees, coughing up sludge and gasping for air. He looked at Izuku. He looked at the trembling, smoking right arm. He looked at the street, completely painted in green sludge, the villain knocked utterly unconscious by the hydrostatic shock.

 

"You..." Katsuki wheezed, his eyes wide, the absolute certainty of his superiority fractured for the very first time. "What... what the hell was that?"

 

Izuku turned his head, his amber lenses reflecting the awe-struck, terrified face of his childhood rival.

 

"I told you, Kacchan," Izuku whispered, a tired, genuine smile crossing his face. "I'm going to U.A. too."

 

The Pro Heroes finally recovered from their shock and swarmed them. The next hour was a blur of paramedics, police tape, and scoldings. Death Arms and Kamui Woods berated Izuku relentlessly for his recklessness, warning him about the illegal use of a Quirk. Yet, beneath their stern reprimands, Izuku’s hyper-vision saw the truth. Their thermal signatures were laced with a cool, vibrant blue—the color of pure, unadulterated awe. They were looking at a fourteen-year-old boy who had just accomplished with a single punch what three Pro Heroes couldn't do with their combined Quirks.

 

Katsuki, conversely, was praised for his resilience, but the explosive boy ignored the heroes. He sat on the back of an ambulance, glaring holes into the pavement, his fists clenched so tight his knuckles were white.

 

Eventually, Izuku was cleared by the paramedics and allowed to walk home. The evening sun was dipping below the horizon, painting the sky in a million shades of ultraviolet and infrared that only Izuku could appreciate.

 

He walked slowly, cradling his right arm against his chest. It hurt, but it was a good hurt. It was the pain of knowing he had saved a life.

 

"Deku!"

 

Izuku stopped. He turned around.

 

Katsuki was storming down the street toward him, his face a mask of furious, conflicted emotion. He stopped a few feet away, his chest heaving.

 

"Listen to me, you nerd!" Katsuki shouted, his voice echoing in the quiet street. "I didn't ask for your help! You didn't save me! I had it under control! I would have gotten out of there myself! Don't you dare think you're better than me just because you have a freak-show punch! You hear me?! I'm still going to be Number One!"

 

Katsuki didn't wait for an answer. He turned and stomped away, his pride desperately trying to glue itself back together.

 

Izuku watched him go. Through his lenses, Katsuki's thermal aura was a chaotic mess of reds, blues, and bright, fearful whites.

 

He's terrified of falling behind, Izuku realized. He's terrified that I'm actually a threat.

 

"He is quite the energetic young man, isn't he?"

 

Izuku spun around.

 

Standing at the entrance of a narrow alleyway, entirely out of sight from the main road, was the skeletal, towering figure of All Might.

 

"All Might," Izuku breathed. "You saw?"

 

"I saw everything," All Might said softly, stepping out of the shadows. The hero's sunken blue eyes were locked onto Izuku with an intensity that made the boy's breath hitch. "I saw the Pro Heroes hesitate. I saw myself, crippled by my own limits, unable to move. And I saw a boy, who knew the devastating toll his power would take on his own body, throw himself into the fire anyway."

 

All Might placed a large, bony hand over his own heart.

 

"Earlier today, you asked me if someone with a lethal Quirk, a Quirk made to destroy, could be a hero. You asked if you could be a Symbol of Peace."

 

All Might stepped forward, dropping to one knee so he was eye-level with Izuku.

 

"Young Midoriya. The essence of heroism is not the power to destroy. It is the instinct to save. When you ran into that fire, your legs moved before you had time to think, didn't they?"

 

Izuku nodded slowly, tears welling up in his eyes, stinging against the neoprene of his goggles. "I couldn't just watch him die. I saw his heat fading. I had to."

 

"That," All Might said, a genuine, radiant smile breaking across his skeletal face, "is what makes a Top Hero. It is a story shared by every great hero in history. Their bodies moved before they had a chance to think."

 

Izuku fell to his knees, his hands clutching his chest, the tears finally flowing freely. For ten years, he had lived as a biological anomaly. He had trained in isolation, fearing his own strength, hiding behind tinted glass to protect his mind from the crushing weight of the world's colors. He had endured the whispers, the fear, and the isolation.

 

And now, the greatest hero in the world was validating his existence.

 

"You can become a hero," All Might declared, his voice ringing with absolute certainty. "In fact, I believe you can become the greatest."

 

Izuku sobbed, pressing his forehead against the asphalt. "Thank you. Thank you."

 

"Stand up, Young Midoriya," All Might said, rising to his full, albeit skinny, height. "You have a gift. A body engineered for supreme kinetic output, and the eyes to calculate the exact application of that force. But you lack technique. You lack control. If you go to U.A. now, you will shatter your arms into dust against the first real villain you face."

 

Izuku looked up, wiping his nose. "I know. My bone density isn't high enough yet. I need to train."

 

"And train you shall," All Might smiled, crossing his arms. "I cannot give you my Quirk, Young Midoriya. But I can give you my experience. I have spent my entire life mastering close-quarters combat, utilizing overwhelming physical force without destroying my surroundings. Your Quirk requires the same discipline."

 

All Might reached out, offering his hand.

 

"I want to make you my personal disciple. Ten months until the U.A. Entrance Exam. Ten months to take that terrifying, beautiful mutation of yours, and forge it into a weapon of absolute justice. What do you say?"

 

Izuku Midoriya looked at the offered hand. Through his sixteen cones of vision, he saw the intricate network of bones, the faint pulse of blood, and the brilliant, undeniable golden aura of the man's heroic spirit.

 

Izuku reached out with his uninjured left hand and gripped All Might’s palm tightly.

 

"I will do whatever it takes," Izuku vowed, his amber lenses reflecting the dying light of the day. "I will be your disciple."

 

The pact was sealed. The apex predator had found his master, and the world was entirely unready for the storm that was coming.

 

 

To forge a sword, one must first subject the steel to unimaginable heat and pressure. The metal must be beaten, folded, and stressed until all impurities are driven out, leaving only a hardened edge capable of cutting through the world.

 

For ten months, Dagobah Municipal Beach Park served as the anvil, and All Might was the hammer.

 

Izuku Midoriya's body, already heavily mutated by the Stomatopod genetics, was put through a regimen that would have killed a normal human. All Might understood a fundamental truth about Izuku’s Quirk: the boy’s striking power was not magical. It was strictly biological and physical. The concussive shockwaves and sonoluminescent flashes were the result of moving physical mass at hypersonic speeds.

 

Therefore, the only way to prevent Izuku from shattering his own skeleton with every punch was to invoke Wolff's Law—the medical principle that bones will adapt to the loads under which they are placed.

 

They did not just clear the trash off the beach. Izuku used the trash.

 

Under the blinding, multi-spectrum glare of the summer sun, filtered through his amber lenses, Izuku stood before a massive block of rusted solid steel, salvaged from the engine block of a discarded freight truck. His upper body was bare, slick with sweat, the dormant gills along his ribcage flaring open and shut, desperately filtering the humid ocean air to supply his massive oxygen demands.

 

"Again!" All Might barked from his lawn chair, currently in his skeletal form, holding a stopwatch. "Your form was sloppy on the recoil! You are letting the kinetic energy bleed into your shoulder joint! The latch must bear the brunt of the reset!"

 

Izuku grit his teeth. He planted his feet in the sand. He drew his right arm back. Deep within his elbow, the biological saddle-latch clicked into place.

 

He didn't strike the air to create a cavitation bubble. He aimed directly at the steel block. This was conditioning.

 

He released the latch.

 

CLANG!

 

The sound of flesh and chitinous bone striking solid steel echoed across the beach like a church bell. Izuku hissed, staggering back, clutching his right forearm. The dense, sub-dermal plating beneath his skin throbbed with the agonizing pain of a thousand microscopic hairline fractures.

 

"Good!" All Might called out, tossing Izuku a chilled thermos. "Drink! Your osteoblasts need fuel to rebuild the bone matrix thicker!"

 

Izuku caught the thermos with his left hand and chugged the contents. It wasn't water. It was a thick, repulsive slurry of bone marrow, calcium powder, liquid protein, and fish oil. It tasted like a fish market blended with chalk, but Izuku drank it down without a complaint. He could literally feel his body demanding the nutrients, his hyper-metabolism instantly going to work repairing the micro-fractures in his ulna, weaving new strands of biological carbon-chitin into the cracks.

 

"You are a weapon of mass kinetic transfer, Young Midoriya," All Might said, standing up and walking over. He traced a bony finger over the fresh indentation Izuku had left in the solid steel block. "But right now, you are a cannon without a carriage. You fire once, and the recoil destroys you. Martial arts is the science of bodily mechanics. You must learn to ground yourself. You must make the Earth absorb your recoil, not your bones."

 

For ten months, this was his life.

 

When he wasn't striking steel to harden his bones, he was sparring with All Might. The Number One Hero, even in his crippled, emaciated form, was a master of close-quarters combat. He taught Izuku how to read momentum, how to slip past a guard, and most importantly, how to strike without engaging the Stomatopod latch. Izuku had to learn how to fight like a normal human, reserving his biological explosive mechanism only for the most desperate of finishing blows.

 

Through his sixteen-cone vision, Izuku watched All Might move. He analyzed the thermal flow of the man's muscles, the kinetic chain linking his footwork to his hips, and down to his fists. Izuku absorbed the information like a sponge, his analytical brain syncing perfectly with his predatory instincts.

 

By the time the ten months were up, the trash on Dagobah Beach was gone.

 

And Izuku Midoriya was unrecognizable.

 

 

 

The morning of the U.A. Entrance Exam was crisp and clear. The cherry blossoms were in full bloom, scattering pale pink petals across the pavement.

 

Izuku stood before his full-length mirror, adjusting the collar of his black middle-school uniform. Beneath the fabric, his physique was a masterclass in biological engineering. The muscle density in his back, shoulders, and core was immense, designed specifically to anchor his arms. The chitinous plating on his forearms had thickened and smoothed out, looking less like bruised scar tissue and more like an organic, matte-grey armor plating naturally integrated into his skin.

 

He reached for the bathroom counter and picked up his newest pair of goggles.

 

They were custom-built, courtesy of a support gear manufacturer Dr. Tsubasa had recommended. They were sleeker than his previous pairs, resembling a high-tech, low-profile tactical visor. The frame was a brushed gunmetal grey, wrapping securely around his temples. The lenses were a deep, mesmerizing, polarized amber. They were highly resilient, capable of withstanding massive concussive shockwaves without shattering.

 

He slipped them on. The overwhelming, shrieking chaos of the morning light was instantly filtered. The world snapped into a beautiful, hyper-detailed focus of thermal auras, stress lines, and polarized clarity.

 

"Izuku!" Inko called from the hallway. "You're going to be late!"

 

Izuku grabbed his yellow backpack, took a deep breath, and stepped out.

 

"I'm ready, Mom," he said.

 

Inko looked at her son, her hands clasped to her chest. She saw the sheer width of his shoulders, the confident set of his jaw, and the mysterious, unreadable amber visor that hid his mutated eyes. He was no longer the crying, Quirkless boy who watched All Might videos on repeat. He was a force of nature.

 

"Do your best, sweetheart," she whispered, tears welling in her eyes.

 

"I will," Izuku smiled, the expression warm and entirely human.

 

 

 

U.A. High School was a fortress of glass and steel, towering over the city like a monument to heroism. As Izuku walked up the massive paved pathway toward the main building, his eyes were in overdrive.

 

Through his lenses, the crowd of hundreds of prospective students was a sea of shifting thermal signatures and structural anomalies. He saw a boy with engines in his legs, the calves radiating intense mechanical heat. He saw a girl whose skin possessed the UV-reflective properties of an amphibian. It was a beautiful, chaotic symphony of genetics.

 

"Out of my way, Deku."

 

The voice was low, dangerous, and dripping with hostility.

 

Izuku didn't need to turn around to know who it was. The explosive thermal signature burning bright red behind him was unmistakable. Katsuki Bakugo walked past him, his hands shoved deep into his pockets, his posture rigid with tension.

 

Ever since the Sludge Villain incident, their dynamic had shifted. Katsuki no longer treated Izuku like a pebble on the road; he treated him like a landmine. There was a wary, aggressive respect hidden beneath the insults.

 

"Good morning, Kacchan," Izuku said calmly, his voice steady. "Good luck today."

 

Katsuki paused, glancing over his shoulder. He glared at the amber lenses. "Don't tell me what to do. I don't need luck. I'm going to set the high score, and you're going to choke on my dust. Try not to break your arms before the exam even starts, bug-eyes."

 

Katsuki marched off. Izuku just shook his head, a faint smirk crossing his face. His heart rate is at 110 BPM. He's nervous too, Izuku noted mentally.

 

Izuku took a step forward, his mind focused on Katsuki's gait, and completely failed to notice his own footing. The tip of his red sneaker caught the edge of a raised paving stone.

 

His center of gravity shifted. He pitched forward, bracing himself for the embarrassing impact of concrete against his face.

 

But the impact never came.

 

Instead, a strange, weightless sensation washed over him. The kinetic pull of gravity simply vanished. He floated, suspended a few inches above the pavement, his arms windmilling comically.

 

"Are you okay?" a cheerful voice asked.

 

Izuku turned his head. A girl with round cheeks and a short, brown bob was standing next to him, her fingers pressed lightly against his backpack.

 

Through his sixteen cones, Izuku’s vision analyzed the girl and her Quirk simultaneously. Her thermal signature was a warm, pleasant pink and yellow. But what fascinated him was the physical interaction of her Quirk. Where her fingertips touched his bag, he could literally see the gravitational field bending. It looked like an absence of pressure, a localized nullification of the kinetic friction that bound mass to the earth.

 

She manipulates gravitons, Izuku's mind fired off instantly. Or she nullifies the mass-energy equivalence equation of an object upon tactile contact. Incredible.

 

"It's my Quirk," she smiled, pressing her fingertips together. Izuku immediately dropped, his boots hitting the pavement with a heavy thud. "Sorry I stopped you without asking, but it'd be bad luck if you fell right before the exam, right?"

 

Izuku stood up, smoothing his uniform. For a moment, the hyper-analytical predator retreated, and the awkward fourteen-year-old boy took over.

 

"Y-Yeah! T-Thank you!" Izuku stammered, bowing slightly. "That's a profoundly versatile localized-gravity manipulation Quirk! The kinetic applications are endless!"

 

The girl blinked, momentarily taken aback by his intense vocabulary, before breaking into a bright laugh. "Wow, you talk fast! I'm Ochaco Uraraka. You look really strong, um...?"

 

"Midoriya. Izuku Midoriya," he said, tapping the rim of his goggles.

 

"Well, good luck, Midoriya!" Uraraka beamed, waving as she jogged off toward the entrance.

 

Izuku watched her go. A null-gravity Quirk. If I struck an object she made weightless... the concussive transfer would face zero resistance. The projectile velocity would be astronomical.

 

He shook his head, pulling himself out of the tactical rabbit hole. Focus.

 

 

 

The written exam was a breeze. Izuku's brain, forced to process millions of colors and inputs simultaneously every waking second, handled calculus and hero-law history with insulting ease.

 

But the real test began in the massive, dimly lit orientation auditorium.

 

Izuku sat next to Katsuki, staring down at the informational pamphlet. On the massive stage, the Voice Hero: Present Mic was screaming into the microphone, his acoustic Quirk vibrating the very walls of the room.

 

Through his visor, Izuku watched the sound waves visually radiating off Present Mic in pulsating, violet rings of kinetic force. It was fascinating.

 

Present Mic explained the rules of the practical exam. An urban battle center. Ten minutes. Three types of robotic "villains," each worth one, two, or three points.

 

"It's like a video game," Izuku muttered to himself, his mind already calculating. "Urban environment means tight corners, verticality. The robots are machines, which means they have joints, power cores, and sensory optics. If I hit them with a full cavitation smash, the collateral shockwave might injure other examinees or deduct points for property damage. I'll need to rely on close-quarters kinetic transfers. Precision strikes. Targeting the structural weak points..."

 

"Excuse me!"

 

A loud, booming voice interrupted Izuku’s frantic muttering.

 

A tall, broad-shouldered boy with glasses was standing up several rows ahead, pointing a stiff, accusatory finger directly 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 of that foolish mistake!"

 

The boy then whipped his stiff arm around, pointing directly at Izuku.

 

"And you, in the back with the ridiculous sunglasses! You've been muttering this entire time! It's distracting! If you are here on a pleasure trip, then you should leave immediately!"

 

The auditorium fell dead silent. Hundreds of eyes turned to look at Izuku. Katsuki beside him let out a low, menacing snort of amusement.

 

Izuku did not shrink into his seat. Ten months of sparring with the Number One Hero had cured him of his intimidation.

 

Izuku calmly stood up. He looked directly at the boy with glasses. Through his amber lenses, Izuku analyzed him.

 

Rigid posture. Perfectly ironed uniform. Intense thermal heat localized strictly in the exhaust pipes on his calves. Elevated heart rate of 120 BPM. He's not angry; he's anxious, projecting his stress into a demand for authoritarian structure.

 

"I apologize if my analysis was distracting," Izuku said, his voice carrying a deep, resonant calm that easily reached the front of the massive room without shouting. "However, these 'sunglasses' are medically prescribed optical dampeners required to regulate a heavily mutated visual cortex. As for the fourth villain, if you consult page four, paragraph two of your syllabus, you will likely see it is an obstacle worth zero points, designed to test avoidance and situational awareness, much like the Thwomp in a Mario game."

 

The silence in the room somehow deepened.

 

The boy with glasses blinked, his rigid posture faltering slightly. He looked down at his pamphlet, flipped to page four, and read it. His face flushed with a sudden spike of bright crimson thermal heat.

 

"I... I see," the boy said, adjusting his glasses nervously. He bowed a perfect ninety degrees toward Izuku. "I deeply apologize for my assumptions regarding your medical equipment! Thank you for the correction!" He bowed to Present Mic and sat down abruptly.

 

Present Mic coughed into his microphone, clearly amused. "Well! Thanks for the assist, Examinee 7111! He's absolutely right! The fourth robot is the Zero Pointer! An obstacle! My advice? Keep away from it!"

 

Izuku sat back down. Katsuki glared at him from the corner of his eye.

 

"Show off," Katsuki muttered.

 

"Just situational awareness, Kacchan," Izuku replied evenly.

 

 

 

Battle Center B was an impressive feat of engineering. It was a massive, enclosed replica of a multi-block urban cityscape, complete with skyscrapers, alleyways, and paved roads.

 

Izuku stood near the front of the massive crowd of examinees, waiting before the towering steel gates. He had stripped off his school jacket, wearing only a tight, black, moisture-wicking undershirt and reinforced cargo pants. His heavily plated, scarred forearms were exposed to the open air.

 

He adjusted his goggles, ensuring the neoprene seal was airtight. He rolled his shoulders.

 

Crack. Click.

 

The biological latches in both of his elbows engaged, locking his arms into a state of immense kinetic tension. He took a deep breath of the humid air, his gills fluttering slightly.

 

He didn't look at the other examinees. He didn't look at the boy with glasses, or Uraraka in the distance. He focused entirely on the massive gates.

 

Click. Click. Click.

 

Izuku’s ears picked up the sound of the heavy internal locking mechanisms of the gates disengaging.

 

"RIGHT, LET'S START!" Present Mic's voice boomed from the hidden loudspeakers.

 

Before the hero even finished his sentence, before the gates had even opened more than three feet, Izuku moved.

 

He didn't run; he detonated.

 

He pushed off his back foot with such explosive, brutal force that the concrete beneath his red sneaker spider-webbed with cracks. He shot through the narrow opening of the gates like a bullet from a rifle, leaving a trail of displaced dust in his wake.

 

"What are you waiting for?!" Present Mic screamed at the rest of the stunned crowd. "There are no countdowns in real battles! Run! Run! That kid with the goggles is already scoring!"

 

The crowd panicked and surged forward.

 

But Izuku was already two blocks deep into the mock city.

 

He sprinted down the center of the street, his multifaceted eyes processing the environment in a million simultaneous calculations. He switched his optical filter, overlaying the thermal spectrum with the electromagnetic spectrum.

 

There.

 

Around the corner of a building to his right, a massive blue aura of electrical current was moving.

 

Izuku rounded the corner without slowing down. He came face-to-face with a Two-Pointer—a bipedal, heavily armored robot with a scorpion-like tail.

 

The robot’s optical sensors flared red. "TARGET ACQUIRED."

 

It swung its massive metal tail in a horizontal arc aimed directly at Izuku's chest.

 

Izuku didn't engage his latch. He didn't use a cavitation strike. That was overkill.

 

Instead, his eyes mapped the exact trajectory of the tail, calculating the velocity and mass. He ducked, letting the massive piece of metal whistle mere millimeters above his head. As the tail passed, exposing the robot's underbelly, Izuku stepped into the machine's guard.

 

Through his lenses, the robot's armor was not a solid piece of metal. It was a complex jigsaw puzzle of interlocking plates, bolts, and servos. Izuku saw the glowing blue line of the main power cable running directly beneath the primary chassis seal.

 

He brought his left hand up, forming a tight, chitin-plated fist. He aimed directly for a microscopic gap between the armor plates.

 

One-inch punch.

 

He struck with the raw, brutal martial arts technique All Might had drilled into him. The force of his hardened fist hitting the exact weak point of the metal was akin to driving a titanium wedge into a crack.

 

The armor plate buckled inward. His fist crushed the power cable beneath it.

 

The Two-Pointer seized, its optical sensors flickering out, and collapsed to the ground in a shower of sparks.

 

"Two points," Izuku muttered.

 

He didn't pause to admire his work. He was already moving.

 

For the next eight minutes, Battle Center B became a hunting ground, and the Stomatopod was the apex predator.

 

Izuku did not fight like a brawler. He fought like a surgeon with a sledgehammer. He darted through the alleyways, wall-running off buildings to gain vertical advantage. His vision allowed him to see the robots coming through walls by tracking their electrical signatures.

 

He encountered a group of three One-Pointers in a tight alleyway. He sprinted directly at them. As the lead robot fired a barrage of rubber bullets, Izuku's eyes tracked the projectiles in slow motion. He weaved through the fire, grabbed the arm of the first robot, and used a judo throw to hurl its massive chassis directly into the other two, crushing them into a heap of scrap metal.

 

"Five points."

 

He vaulted over a burning car and landed gracefully on the hood of another. A massive Three-Pointer, built like a tank on treads, locked onto him.

 

The Three-Pointer fired a net-cannon.

 

Izuku engaged his right elbow latch. Five percent output.

 

He flicked his arm. A miniature, localized shockwave exploded from his knuckles, generating a burst of high-pressure air that blew the heavy net back into the robot's own optical sensors, blinding it.

 

Izuku closed the distance, leapt into the air, and delivered a devastating, spinning heel kick directly to the robot's central turret ring, decapitating the machine with sheer kinetic transfer.

 

"Eight points."

 

The other examinees were awestruck. They watched this kid with the dark visor and the scarred arms dismantle multi-million-yen machines with terrifying, surgical precision. He wasn't using massive explosions or flashy elemental attacks. He was just hitting them. But he was hitting them so perfectly, so impossibly hard, that the robots were folding like tin cans.

 

 

 

High above the Battle Centers, in a darkened, multi-monitor observation deck, the faculty of U.A. High School watched the carnage.

 

"Incredible," the Pro Hero Midnight murmured, her eyes wide as she watched a feed from Center B. "Look at Examinee Midoriya. His situational awareness is off the charts. He hasn't taken a single hit."

 

"He's not just breaking them," the exhausted, bandage-wrapped Pro Hero Aizawa noted from his sleeping bag in the corner. His dark eyes narrowed at the screen. "He's dissecting them. He knows exactly where the servos, power lines, and structural joints are. He's expending the absolute minimum amount of energy required to neutralize the target."

 

"A mutant-type Quirk with enhanced physical parameters?" the principal, a dog-mouse-bear creature named Nezu, squeaked from his chair.

 

"Not just physical," All Might, in his overly-muscular hero form, boomed proudly from the back of the room. "His Quirk is called Stomatopod. His eyes are highly advanced. He can see across multiple spectrums of light. He's literally seeing their weak points."

 

Aizawa raised an eyebrow. "Is that so? He's a lethal weapon, then. Let's see how he handles something he can't just punch a hole in. It's time to test their true mettle."

 

Nezu smiled, lifting a small plastic cover on his console and pressing a large red button.

 

"Release the Zero Pointers."

 

 

 

Izuku stood atop a pile of demolished Two-Pointers, wiping a bead of sweat from his forehead. His breathing was heavy, the gills on his sides working overtime.

 

Forty-seven points, he calculated. That should be easily within the passing threshold. I just need to maintain my stamina for the last two minutes—

 

The ground beneath him lurched violently.

 

It wasn't a tremor. It was an earthquake. The asphalt of the main street split open with a deafening roar.

 

Izuku snapped his head around. Through his visor, the thermal and electromagnetic readings of the surrounding area spiked to catastrophic levels.

 

Bursting through the buildings at the far end of the street was a machine of biblical proportions.

 

The Zero Pointer.

 

It was taller than the surrounding skyscrapers, a colossal, bipedal monstrosity rolling forward on massive tank treads, its upper body resembling a heavily armored fortress. The sheer weight of it crushed entire buildings into powder as it moved.

 

Panic erupted. The examinees, who had been fighting bravely moments ago, broke and ran.

 

"Run away!"

"It's the Zero Pointer! We can't fight that!"

"Time's almost up! Just run!"

 

Izuku watched the retreating crowd. His logical brain agreed with them. The Zero Pointer was an obstacle. It awarded no points. Engaging it was an unnecessary risk of stamina and life. He turned to follow the crowd.

 

Help...

 

The sound was tiny, drowned out by the grinding gears of the colossus.

 

But Izuku didn't just hear it. He turned back, his multifaceted eyes piercing through the massive, suffocating cloud of dust and debris kicked up by the machine. He switched to thermal imaging.

 

Trapped beneath a massive slab of concrete rubble, directly in the path of the Zero Pointer's advancing treads, was a bright, pulsing pink-and-yellow thermal signature.

 

Uraraka.

 

Her leg was pinned. She was desperately trying to use her Quirk to lift the rubble, but she was exhausted, her thermal aura dimming from overuse.

 

The Zero Pointer raised a massive, building-sized hand, preparing to crush the entire intersection.

 

Time stopped for Izuku Midoriya.

 

Ten months ago, All Might had told him that the essence of a hero was the instinct to save. That a true hero's body moved before they had a chance to think.

 

Izuku didn't think about his points. He didn't think about the entrance exam. He didn't even think about the terrifying limits of his own body.

 

He moved.

 

He sprinted against the tide of fleeing students, running directly toward the apocalypse.

 

"Hey! What are you doing?!" a student screamed at him. "Are you crazy?!"

 

Izuku ignored him. As he closed the distance, his predatory brain engaged in a hyper-fast tactical analysis of the colossus before him.

 

It's too tall to jump over. The armor on its face and chest is too thick for a mid-air cavitation strike without solid footing. But it's top-heavy. It relies on the massive hydraulic servos in the ankle-tread joints to maintain its center of gravity. If I destroy the base, physics will do the rest.

 

Izuku reached the Zero Pointer. The massive metal treads, each the size of a bus, were grinding the pavement into dust.

 

He didn't leap toward its face. He ran directly underneath the massive shadow of its leg, sliding across the concrete to stop right beside the main, primary articulation joint that connected the tread to the upper leg chassis.

 

The joint was made of solid, reinforced titanium, glowing blindingly bright with electrical current and friction heat in Izuku's vision.

 

Izuku planted his left foot forward, dropping into a deep, incredibly low martial arts stance. He anchored his body to the earth, digging his sneakers into the asphalt.

 

He reached across his body with his left hand, grabbing his right forearm, physically bracing the limb.

 

Deep within his right arm, the biological mechanism clicked into place. But this wasn't five percent. This wasn't fifty percent.

 

This was a machine that weighed thousands of tons. This required the absolute, uncapped limit of his genetic mutation.

 

One Hundred Percent Output.

 

Every muscle in his right arm coiled so tightly that the chitinous armor on his skin cracked. His bicep swelled dangerously, the veins glowing purple beneath his skin. The pain was immediate and agonizing, but he pushed past it.

 

The Zero Pointer's massive foot began to lower, threatening to crush Uraraka a few yards away.

 

Izuku looked at the titanium joint.

 

SMAAAAASH!

 

He released the latch.

 

His arm did not blur. It simply disappeared from human perception.

 

The speed of the strike instantly broke the sound barrier, generating a macroscopic sonic boom that shattered every remaining pane of glass in a three-block radius.

 

His heavily armored knuckles struck the exact dead-center of the titanium joint.

 

But it wasn't the physical impact that doomed the machine. It was the cavitation.

 

A massive vacuum bubble, five feet in diameter, formed instantly at the point of impact. The air pressure dropped to absolute zero. And then, a microsecond later, the atmosphere rushed back in to fill the void.

 

The collapse of the bubble unleashed a blinding, biblical flash of sonoluminescent light. For a fraction of a second, a miniature star ignited in the streets of Battle Center B. The heat flash-melted the titanium joint instantly into a glowing orange slag.

 

And then came the shockwave.

 

KRA-OOOOOOOOOOOOOOM!

 

The concussive force was apocalyptic. A massive, visible dome of compressed air exploded outward. The asphalt of the street was ripped up and hurled away like paper in a hurricane.

 

The shockwave hit the Zero Pointer’s crippled leg. The sheer kinetic force, combined with the melted joint, caused the entire massive limb to simply detonate. The leg was blown clean off the chassis, hurled hundreds of feet down the street.

 

Without its primary support, the thousands of tons of metal making up the upper body of the Zero Pointer shifted.

 

The colossus groaned, a terrifying sound of screeching, twisting metal. It tilted backward, away from Uraraka, away from the students.

 

Slowly, agonizingly, the Zero Pointer toppled over backward, crashing into the faux-cityscape with an impact that registered on seismographs miles away. Dust plumed hundreds of feet into the air.

 

Silence descended upon Battle Center B.

 

In the observation room, the Pro Heroes stared at the monitors in absolute, stunned silence. The camera feeds near the incident had been completely fried by the flash of light and EMP generated by the strike.

 

On the street, the dust slowly began to clear.

 

Uraraka lay on the ground, the rubble holding her down having been blown away by the periphery of the shockwave. She coughed, looking up through the haze.

 

Standing a few yards away was Izuku.

 

He was still in his deep stance. But he wasn't moving.

 

His right arm hung entirely limp at his side. The sleeve of his shirt had been completely vaporized. His arm was a grotesque, terrifying shade of purple and black. The chitinous plating that had taken ten months to build was shattered, splintered outward like broken glass. His bones, unable to withstand the apocalyptic recoil of a one-hundred-percent output, were pulverized.

 

Blood dripped steadily from his fingertips onto the pavement.

 

"TIME'S UP!" Present Mic's voice finally echoed over the PA system, though it sounded incredibly small compared to the silence.

 

Izuku slowly turned his head toward Uraraka. His amber goggles were cracked, a large spider-web fracture running across the right lens.

 

"Are you... okay?" Izuku rasped, his voice trembling violently.

 

Uraraka stared at him, tears welling in her eyes, completely overwhelmed by the sheer, terrifying sacrifice he had just made for her. "I... I'm okay."

 

Izuku smiled, a small, pained expression.

 

And then, his eyes rolled back, his brain finally allowing the pain to register, and he collapsed forward, falling unconscious before he hit the ground.

 

 

 

He woke up in the U.A. infirmary.

 

The room was bathed in a soft, dim light. Izuku groaned, trying to sit up, but a sharp, agonizing spike of pain in his right arm pinned him back to the bed.

 

He looked down. His entire right arm, from the shoulder to the fingertips, was encased in a massive, heavy-duty medical cast.

 

"Ah, the boy with the cannon for an arm is awake," a crotchety voice said.

 

Izuku turned his head. Sitting on a stool next to his bed was Recovery Girl, the Youthful Heroine. She was looking at a clipboard, shaking her head.

 

"I've seen self-destructive Quirks in my time, sonny, but your biology is a nightmare," she scolded, tapping her cane against his bed. "I used my Quirk to accelerate your healing, but your bones... they aren't normal. That chitinous structure took an immense amount of your body's stamina to rebuild. You'll be exhausted for a week."

 

"The girl... Uraraka?" Izuku rasped.

 

"She's fine," Recovery Girl sighed. "Not a scratch on her. She came in here crying her eyes out, thanking you. You saved her life, kid."

 

Izuku relaxed, sinking back into the pillows. "Good."

 

"Not good!" Recovery Girl whacked his good arm lightly with her cane. "You pulverized your own ulna and radius into dust! If your bones weren't mutated to be denser than steel, that strike would have blown your arm clean off your body! You cannot use that level of power again until you are fully grown, do you understand me?"

 

"Yes, ma'am," Izuku whispered.

 

Recovery Girl sighed, her expression softening. "You're a brave kid. Stupid, but brave. Get some rest. The results of the exam will be mailed in a week."

 

 

 

The week of waiting was its own kind of torture.

 

Izuku spent his time resting, his body aggressively consuming calories as it worked overtime to repair the massive trauma to his right arm. He ate constantly, his gills flaring in the humidified air of his bedroom as he stared blankly at his posters of All Might.

 

He was terrified.

 

He had forty-seven points. Was that enough? He had broken his arm, failing to maintain control of his Quirk just like All Might had warned him not to. Had he ruined his chances?

 

Finally, the letter arrived.

 

Inko brought it into his room, her hands shaking, before quickly leaving him alone. It wasn't a standard paper letter. It was a small, heavy metallic disc.

 

Izuku placed it on his desk. He took a deep breath, and pressed the button on top.

 

A holographic projection sprang to life.

 

"I AM HERE AS A PROJECTION!"

 

All Might’s booming voice filled the room. The hero was in his muscle form, wearing a sharp yellow suit.

 

"Young Midoriya!" All Might smiled warmly. "I know it has been a tense week! You did an excellent job on the written test. But the practical... ah, the practical."

 

All Might's expression grew serious.

 

"You scored forty-seven villain points. A respectable score. However... in the eyes of the judges, destroying an obstacle worth zero points to save a single life..."

 

The hologram shifted, showing a video of Izuku. Not fighting, but standing before the massive Zero Pointer, his arm shattered, asking Uraraka if she was okay.

 

"...is the very definition of a hero."

 

All Might beamed. "U.A. is a hero school, Young Midoriya! We do not just grade on destruction! We grade on the instinct to save! Rescue Points! And a panel of judges awarded you... sixty Rescue Points!"

 

A scoreboard appeared on the projection.

 

Izuku’s name shot to the very top.

 

1. Bakugo Katsuki - 77 Villain Points, 0 Rescue Points.

2. Midoriya Izuku - 47 Villain Points, 60 Rescue Points. Total: 107 Points.

 

Izuku stared at the number. One hundred and seven. He had beaten Katsuki. He had set the high score.

 

"You passed with flying colors, Young Midoriya!" All Might laughed, pointing directly at the camera. "You have proven that even a weapon designed for destruction can be wielded by a heart of gold. Come, Young Midoriya. This is your Hero Academia!"

 

The projection faded out.

 

Izuku sat in his chair, the silence of his room ringing in his ears. He looked down at his heavy cast. He felt the ache in his bones, the relentless throb of a body pushed beyond its limits.

 

He reached up and pulled his broken, fractured amber goggles off his face, setting them gently on the desk next to the projector.

 

He covered his face with his uninjured hand, and for the first time in ten months, he cried not from pain, but from absolute, unadulterated joy.

 

He had shattered the shell. He was going to U.A.
