What if deku was a crocodile human hybrid

 

The morning alarm didn’t just wake Izuku Midoriya; it startled him, prompting a violent, instinctual thrash that sent his heavy, armored tail slamming into the bedroom wall.

 

CRACK.

 

The plaster fractured, a web of spider-webbing fissures spreading outward from the point of impact. Izuku gasped, his slitted, golden eyes snapping open. He immediately shrank in on himself, bringing his massive, scaled hands to his snout as he stared at the fresh dent in the wall.

 

"Ah, man," he hissed, his voice deeper than a boy of fourteen had any right to possess, carrying a natural, rattling resonance that sounded like stones grinding together. "Not again."

 

He carefully threw off his custom-made, oversized blanket. The sheer physical reality of Izuku Midoriya was something that took up space. Standing at a towering six-foot-two—a height he had reached just last year with no signs of stopping—he was a hulking mass of dark, emerald-green scales, rippling muscle, and primal biology. His legs were digitigrade, bending backward at the ankle like a predator’s, forcing him to walk on heavily padded, clawed toes. A massive, heavily ridged tail dragged behind him, a muscular appendage that accounted for nearly a third of his body weight.

 

He was a mutant. A crocodile-human hybrid. In a world where eighty percent of the population possessed a superpower known as a Quirk, Izuku was a rare, extreme case of genetic mutation. Society categorized his Quirk as Apex Reptile. Society also had other words for it. Monster. Villain-in-training. Beast.

 

Izuku shuffled toward his bathroom, his claws clicking rhythmically against the hardwood floor. Click. Clack. Click. Clack. It was a sound he actively tried to muffle, often walking on the sides of his feet so he wouldn't disturb his mother, though it was an exercise in futility.

 

The air in the apartment was warm. His mother, Inko, always kept the thermostat cranked up to uncomfortable levels for a normal human, but for Izuku, it was necessary. Being cold-blooded meant that when the temperature dropped, his heart rate slowed, his thoughts grew foggy, and his limbs felt like they were filled with wet cement. Now, in early spring, the mornings were still brisk enough to make him sluggish.

 

He stood before the bathroom mirror and let out a long, rumbling sigh.

 

The reflection staring back at him was the stuff of nightmares. His skin was completely covered in thick, interlocking scutes, dark green on his back and head, fading into a pale, yellowish-cream across his chest and underbelly. His face was a strange, terrifying amalgamation of human and reptile. He had the general structure of a human face—cheekbones, a brow ridge, a nose—but his jaw was elongated, stretching out into a terrifying maw lined with seventy-two razor-sharp, conical teeth. He had no lips to speak of, meaning his teeth were perpetually visible, locked in what looked like a permanent, menacing sneer.

 

"Okay," Izuku muttered, grabbing a heavy-duty scrub brush and his specially formulated toothpaste. "Smile practice."

 

He gripped the edges of the sink and pulled the corners of his mouth back, trying to emulate the bright, reassuring grin of the Number One Hero, All Might.

 

The result was horrifying.

 

When Izuku smiled, his jaw unhinged slightly, revealing rows of jagged daggers and the dark, fleshy depths of his throat. His slitted pupils dilated with the effort, making him look like a starving predator about to lunge at a piece of meat. He dropped the expression immediately, his broad, scaled shoulders slumping.

 

"Still too scary," he whispered, a deep sadness coloring his gravelly voice.

 

He spent the next twenty minutes brushing his teeth—a meticulous, necessary process—and scrubbing down his scales with a pumice stone to clear away any shedding skin. Dressing was another hurdle. His Aldera Junior High uniform was specially tailored. The trousers were wide and lacked a back seam to accommodate his thick tail, and the shoes were essentially reinforced, open-toed sandals designed to strap over his digitigrade feet without crushing his claws.

 

When he finally emerged into the kitchen, the smell of sizzling meat greeted him.

 

"Good morning, Izuku!" his mother, Inko Midoriya, called out cheerfully. She was a small, plump woman with kind eyes and soft green hair. The contrast between her and her son was almost comical. She looked like the quintessential, loving mother. He looked like something that had crawled out of a prehistoric swamp to terrorize a city.

 

"M-Morning, Mom," Izuku stammered softly, taking a seat at the reinforced steel dining chair she had bought for him after he had accidentally crushed three wooden ones.

 

"I made your favorite," she said, using her telekinetic Quirk to float a massive plate toward him. It wasn't pancakes or eggs. It was a staggering pile of rare steaks, chicken breasts, and fish. His crocodilian metabolism required massive amounts of protein, and his digestive system, capable of dissolving bone, could handle it easily.

 

"Thanks, Mom. You didn't have to cook this much," he mumbled, picking up a piece of chicken. He didn't chew it much. He couldn't. Crocodilian teeth were made for gripping and tearing, not chewing. He swallowed it in two bites.

 

Inko looked at him, her eyes softening with that familiar, painful mix of immense love and deep-seated guilt. She and his father, Hisashi, had possessed simple Quirks—weak telekinesis and minor fire-breathing. The doctors had explained that Izuku’s mutation was a million-to-one genetic lottery, a spontaneous throwback to some distant, ancient, reptilian ancestor in their bloodline, supercharged by modern Quirk genetics.

 

"Did you sleep well, sweetie? I heard a thump."

 

"Ah... y-yeah. I just had a dream, I think. Spooked myself and hit the wall. I'm sorry. I'll patch the drywall this weekend," he said, rubbing the back of his neck, a gesture made awkward by the thick, armored plates running down his spine.

 

"Don't worry about the wall, Izuku," Inko said softly, reaching out to pat his massive, clawed hand. Her small, soft fingers rested against his cold, hard scales. "Just... be careful out there today, okay?"

 

She didn't mean 'be careful' in the way other mothers meant it. She meant be careful not to scare anyone. Be careful not to let them hurt your feelings. Be careful because the world does not love things that look like you.

 

"I will," Izuku promised, offering her a closed-mouth nod that was the closest he could get to a gentle smile.

 

 

 

The walk to Aldera Junior High was an exercise in self-shrinkage.

 

Izuku hated his size. He hated the way his broad shoulders practically took up the entire sidewalk. He hated the heavy, rhythmic thud, thwack, thud, thwack his tail made as it dragged behind him, forcing him to expend immense core strength just to keep it slightly elevated off the concrete so he wouldn't trip anyone.

 

Most of all, he hated the stares.

 

It was a beautiful Tuesday morning in Musutafu. Cherry blossoms were blooming, the sun was shining, and the streets were bustling with commuters. And yet, wherever Izuku walked, a bubble of isolation formed around him.

 

He saw it happen in real-time. A mother walking her toddler, laughing about something, suddenly catching sight of Izuku. Her eyes would widen, her breath hitching, and she would unconsciously pull her child to the other side of the street, shielding the kid’s eyes as if Izuku were a horror movie playing out in broad daylight.

 

I'm not going to hurt you, Izuku thought desperately, dropping his gaze to the pavement. I'm just going to school. I'm just a kid.

 

He pulled his yellow backpack higher onto his shoulders, hunching over to make himself appear smaller. It didn’t work. He was a leviathan in a sea of normal people.

 

Suddenly, a loud crash echoed from the nearby train station. Izuku’s sensitive hearing picked up the sound of screaming, followed by a booming voice demanding money. His slitted eyes widened. A villain attack!

 

The instinct to run away, to hide from loud noises and danger, was a natural part of human survival. But Izuku’s heart was wired differently. The moment he heard the cry for help, a surge of adrenaline chased away the morning chill in his cold blood. He broke into a heavy jog, his powerful legs eating up the distance in massive strides, his tail balancing his weight perfectly.

 

He arrived at the station crossing just as a massive, shark-headed villain was swatting away police cars. The villain roared, swinging a massive girder.

 

Izuku’s breath caught in awe as Kamui Woods swung into the fray, his wooden limbs extending. Izuku immediately reached into his backpack, his thick claws delicately unzipping the small pocket to pull out a charred, battered notebook labeled Hero Analysis for the Future No. 13. He clicked a pen, his terrifying eyes tracking the hero’s movements with intense, analytical precision.

 

"Kamui Woods is engaging," Izuku muttered to himself, his voice a low rumble. "His wood-binding technique is incredibly effective for restraint, but against a villain with that much raw physical strength, he needs to secure the joints first. If he goes for the wrists, the villain can just pull him in..."

 

"Hey, look at that monster," a voice whispered nearby.

 

Izuku flinched. He stopped writing and glanced out of the corner of his eye. Two middle-aged men were standing a few feet away, pointing not at the giant villain, but at him.

 

"Think he's with the villain?" one muttered.

 

"Look at those teeth. He shouldn't be allowed to just walk around like that. He looks like he eats people," the other said, shivering.

 

The pen in Izuku’s hand nearly snapped under the sudden pressure of his claws. He lowered his head, the joy of watching the hero fight instantly evaporating. He closed his notebook, sliding it back into his bag. He didn't stay to watch Mt. Lady arrive and steal the glory. He turned away, his heavy tail dragging on the ground once more, and continued his march to school.

 

 

 

Aldera Junior High was not a haven. It was a cage.

 

When Izuku stepped into Classroom 3-A, the usual morning chatter dipped in volume. It didn't stop completely—they were used to him by now—but the shift in atmosphere was palpable. It was the kind of tension that happens when a predator enters the room.

 

Izuku squeezed his massive frame into his desk at the back of the class. The school had been forced to remove the desk attached to the chair, giving him a standalone table so his knees and tail could fit. He sat down, wrapping his heavy tail around the base of his chair to keep it out of the aisles, folding his arms on the desk, and staring at the chalkboard.

 

"Alright, settle down," their homeroom teacher said, walking into the room with a stack of papers. "As third-year students, it's time to start thinking seriously about your futures and what you want to do with your lives. I could pass out these career aptitude tests, but..." The teacher smirked, tossing the papers into the air. "Why bother? I know you all want to go to the Hero Course!"

 

The classroom erupted in cheers. Students activated their Quirks—stretching limbs, shooting water, sparking minor fires.

 

Izuku didn't cheer. He just quietly raised his hand, a small, hopeful gesture that was completely overshadowed by the chaos.

 

"Yes, yes, you all have wonderful Quirks," the teacher said, placating the crowd. "But remember, using your powers in school is against the rules! Now, let's see... Katsuki Bakugo, you're aiming for U.A. High School, aren't you?"

 

The room went dead silent.

 

Sitting a few rows ahead of Izuku, a boy with spiky ash-blonde hair kicked his feet up onto his desk. Katsuki Bakugo leaned back, an arrogant, confident smirk on his face. "Don't lump me in with these background characters, teach. I'm not gonna be stuck at the bottom with the rest of these rejects. I pulled an 'A' in the mock tests. I'm the only one here with the stuff to make it into U.A. I'm gonna surpass All Might and become the top hero!"

 

The class broke into murmurs of awe and annoyance, but no one challenged him. Bakugo was strong. His Explosion Quirk was powerful, versatile, and terrifying.

 

"Oh, yeah," the teacher said, glancing at a clipboard. "Midoriya... you applied for U.A. too, didn't you?"

 

The temperature in the room seemed to plummet.

 

Every single head turned to look at the back of the room. Izuku froze, his golden eyes widening in panic. He could feel the stares. They weren't just looking at him; they were examining him. Looking at the thick green scales, the terrifying snout, the predatory claws.

 

For a moment, there was nothing. Then, someone whispered.

 

"Him? A hero?"

 

"He'd give the hostages a heart attack."

 

"I bet the villains would recruit him on the spot."

 

"Is U.A. running a zoo now?"

 

Izuku shrank back, his large hands gripping his knees. "T-There's no rule against it," he stammered, his gravelly voice trembling. "T-They removed the rule against mutant-types taking the physical exam years ago... I-I just want to try..."

 

BOOM!

 

A blinding flash of heat and light erupted across Izuku’s desk. The sheer force of the explosion blew Izuku backward. He crashed onto the floor, his heavy tail whipping wildly to break his fall, shattering a nearby chair.

 

Izuku scrambled backward, his slitted eyes darting up to see Bakugo standing over him, smoke rising from his palms.

 

"Listen to me, you useless beast," Bakugo sneered, his red eyes glaring down with unadulterated disgust.

 

Bakugo didn't call him 'Deku' because Izuku was Quirkless. No, in this world, Izuku had a Quirk. But to Bakugo, a Quirk that only turned you into a mindless, ugly animal was worse than having no Quirk at all. 'Deku' meant a wooden doll, a useless thing. To Bakugo, Izuku was just a big, dumb, ugly lizard masquerading as a person.

 

Izuku’s scales were incredibly thick. They were practically bulletproof. A normal punch, a knife, even a baseball bat would shatter against his hide. But Bakugo’s Quirk was his natural enemy. The intense heat of the explosions threatened to dry out Izuku’s skin, and the concussive, deafening boom overloaded his highly sensitive crocodilian hearing.

 

"A-Kacchan," Izuku wheezed, his ears ringing terribly. He held his clawed hands up in surrender, actively suppressing every instinct in his body that screamed at him to snap his jaws, to lash out, to protect himself. He forced his claws to stay open. I am not a monster. I will not attack him. I am a hero.

 

"You think they'd let a freak like you into U.A.?" Bakugo stepped forward, pressing a smoking palm against Izuku’s armored chest. The heat made Izuku wince, his scales warming uncomfortably. "A hero has to make people feel safe. When people look at you, they don't see hope. They see a villain. They see a goddamn monster. What are you gonna do in the exam, huh? Bite someone's head off?"

 

"I-I wouldn't!" Izuku pleaded, his voice cracking. "I just... I want to save people, Kacchan! Just like All Might! I can control myself, I promise!"

 

"You're a hazard just by breathing, Deku," Bakugo spat, turning away. "Do us all a favor and withdraw your application. Before I decide to turn you into a pair of boots."

 

The class laughed nervously. Izuku slowly picked himself up from the floor, righting his desk. His tail hung limply, a physical manifestation of his crushed spirit. He didn't look up for the rest of the day.

 

 

 

The final bell rang, signaling the end of the school day. Izuku remained in his seat, slowly packing his bag. He wanted to wait until the halls were empty so he wouldn't bump into anyone.

 

He pulled out his charred Hero Analysis notebook. The cover was blackened from Bakugo's explosion, but the notes inside were legible. He traced his sharp claw over the signature of All Might he had printed on the inside cover.

 

A hero has to make people feel safe.

 

Bakugo's words echoed in his mind, cruel but echoing a fear Izuku had carried his entire life.

 

Izuku closed his eyes, the memory rushing back with the clarity of a high-definition film. He couldn't stop it. The trauma of his awakening was carved into his bones.

 

He was four years old. Up until that point, he had been a completely normal, chubby-cheeked boy with green hair and freckles. He and Bakugo used to play together, pretending to be All Might in the woods behind their houses.

 

Then, the fever hit.

 

It started as a burning in his skin. His mother had rushed him to the hospital when his temperature spiked to dangerous levels. Izuku remembered lying in the hospital bed, screaming in agony as his bones began to shift. The doctors were baffled. It wasn't a normal Quirk manifestation.

 

Over the course of three agonizing weeks, Izuku's humanity was stripped away. His soft skin hardened, breaking out into thick, green scutes. His spine elongated, breaking through the skin of his lower back to form a heavy, muscular tail. The worst was his face. His jaw had fractured and reshaped itself, pushing outward into a snout. His baby teeth had fallen out all at once, replaced within days by jagged, terrifying fangs. His round, innocent eyes had turned a piercing gold, his pupils narrowing into slits.

 

When he finally returned home, he wasn't the same. The neighborhood kids, who used to be his friends, took one look at him and ran away screaming.

 

He remembered sitting in the dirt at the playground, watching Bakugo and the others play from afar. A boy named Tsubasa had tripped and scraped his knee, crying. Izuku, his heart full of the desire to help, had run over.

 

"Are you okay?" four-year-old Izuku had asked, reaching out a scaled, clawed hand to help the boy up.

 

Tsubasa had looked up, seen the terrifying, toothy maw and the slitted eyes, and screamed in absolute, primal terror. He scrambled backward, terrified out of his mind. Bakugo had stepped between them, his hands sparking with early explosions.

 

"Get back, monster!" Bakugo had shouted. "Don't eat him!"

 

"I-I wasn't going to!" Izuku had cried, tears falling from his reptilian eyes. "I just wanted to help!"

 

"Heroes don't look like you!" Bakugo had declared, pointing a finger at Izuku’s chest. "You look like the bad guy! You're just a Deku! A useless, ugly beast!"

 

Izuku had run home that day, locking himself in his room. He had pulled up the famous video of All Might saving a hundred people from a disaster. He watched the Symbol of Peace smile, his bright, reassuring grin telling the world that everything was okay.

 

Inko had found him sitting in the dark, the glow of the monitor illuminating his terrifying, mutated features. He was pointing at the screen, tears streaming down his scaly snout.

 

"Mom," little Izuku had asked, his voice already dropping an octave into a gravelly rumble. "He saves everyone with a smile. Even if I look like this... even if everyone is scared of me... can I be a hero too?"

 

His mother had broken down. She hadn't said yes. She had run to him, throwing her arms around his bulky, armored form, crying and apologizing over and over. 'I'm sorry, Izuku! I'm so sorry!'

 

That was the day Izuku realized the truth. His mother loved him, but even she didn't believe a monster could be a hero.

 

Izuku opened his eyes, snapping back to the present. The classroom was empty. The afternoon sun cast long, orange shadows across the desks.

 

"I'm not a beast," Izuku whispered to the empty room. "I'm not."

 

He grabbed his bag and slung it over his shoulder. He left the classroom, his heavy footsteps echoing in the quiet hallway.

 

As he exited the school gates, he took a detour. Instead of taking the main street home, which would be crowded with people doing their evening shopping, he opted for the longer, darker route under the overpass. It was a secluded path, following a shallow, concrete-lined river. It smelled of damp earth and stagnant water—a smell that, to his immense frustration, his crocodilian biology found comforting.

 

He dragged his feet, his tail leaving a shallow groove in the dirt beside the paved path.

 

He thought about the future. Could he really go to U.A.? The physical exam wouldn't be an issue. His Quirk granted him superhuman strength, immense durability, and a jaw bite force of over three thousand pounds per square inch. He could tear through metal if he had to.

 

But what about the interview? What about the rescue points? If a building was collapsing and he reached out to save someone, would they take his clawed hand, or would they recoil in fear and choose to fall?

 

“When people look at you, they don't see hope. They see a villain.”

 

"Stop it," Izuku muttered, slapping his own cheeks with both hands to snap himself out of it. "Negative thoughts won't get you anywhere. I just have to work twice as hard to show them my heart. I'll smile so brightly they'll forget about the teeth. I'll..."

 

A strange sound interrupted his monologue.

 

Gurgle. Squelch.

 

Izuku paused. His slitted eyes dilated, letting in more light in the dimness of the underpass. His external auditory canals swiveled slightly beneath his scales. The sound was coming from a manhole cover a few yards ahead.

 

Clang. Shhhhck.

 

The heavy iron cover shuddered, then was violently pushed aside. From the dark depths of the sewer, a mass of dark, putrid green sludge erupted onto the pavement. It piled higher and higher, forming a towering, amorphous blob. Two massive, bulbous eyes opened within the liquid, followed by a jagged mouth filled with uneven teeth.

 

Izuku’s breath caught. His primal instincts—the deep, ancient part of his brain that controlled his fight-or-flight response—flared to life. The scales on the back of his neck bristled. This wasn't a person. This was a predator. And it was looking at him.

 

"Well, well, well," the Sludge Villain gurgled, his voice a wet, echoing rasp. "A medium-sized meat shield. You're a bit freakish, kid, but you'll do nicely. I need a place to hide."

 

Izuku took a step back, his heavy tail tensing behind him. "W-What do you want?" he demanded, trying to sound brave, though his voice wavered.

 

"Just your body!" the villain cackled, lunging forward with terrifying speed.

 

A tidal wave of foul-smelling sludge crashed over Izuku. The impact was heavy, like being hit by a truck made of wet cement. Izuku roared, a deep, guttural sound, and planted his digitigrade feet into the concrete, his claws digging deep gouges into the stone to keep from being bowled over.

 

The sludge wrapped around his massive torso, slick and suffocating.

 

No! Izuku panicked, his arms flailing. He slashed out with his razor-sharp claws, aiming for the villain's eyes. His claws, capable of rending steel, tore right through the liquid mass. It splashed harmlessly and instantly reformed.

 

"Physical attacks? Nice try, lizard!" the villain laughed, the sludge creeping up Izuku’s chest, wrapping around his thick neck. "I'm fluid! You can't punch water!"

 

Izuku thrashed violently. He whipped his tail, smashing it against the concrete pillars of the overpass, creating deafening cracks that echoed through the tunnel. But no matter how hard he fought, the sludge clung to him.

 

Then, the sludge surged toward his face.

 

He's trying to get inside! Izuku realized with dawning horror.

 

The villain forced a tendril of sludge into Izuku’s mouth. Izuku immediately clamped his jaws shut. His bite force was legendary. His seventy-two teeth locked together like a steel trap, severing the tendril.

 

"Ouch! Feisty beast, aren't you?" the villain hissed. "But you have to breathe eventually, kid!"

 

The sludge enveloped Izuku’s snout, blocking his nostrils. The darkness closed in.

 

Panic, cold and absolute, gripped Izuku’s heart. His crocodilian biology was unique. In water, under the right conditions, he could hold his breath for up to two hours. But that was when he was calm, when his heart rate was slowed. Right now, surging with adrenaline and burning oxygen as he wrestled a supervillain, his lungs were screaming for air.

 

He clawed at his own face, desperately trying to rip the sludge away from his snout. His sharp claws scratched against his own indestructible scales, leaving shallow white lines, but the liquid just flowed around his fingers.

 

"Just hold still!" the villain sneered, tightening his grip. "It'll only hurt for about forty-five seconds! Then I'll take the wheel!"

 

I can't... I can't breathe, Izuku thought, his frantic movements beginning to slow. His massive arms felt heavy. The immense strength of his mutant body was useless if he couldn't hit his target. He was suffocating.

 

Is this it? he thought, his golden eyes wide and bloodshot, staring at the concrete ceiling of the tunnel. Is this how I die? In a dark tunnel... treated like an animal... never proving them wrong?

 

The faces of his classmates flashed through his mind. Bakugo's sneer. The terrified cries of the children at the playground. His mother's weeping face.

 

I never got to be a hero.

 

A tear broke free from his eye, mixing with the foul sludge. His knees buckled. The towering, armored beast crashed to the ground, his tail lying limp on the pavement. The darkness at the edge of his vision began to creep inward, swallowing the light.

 

I'm sorry, Mom.

 

Suddenly, a massive, reverberating CLANG echoed through the tunnel.

 

The vibration traveled through the concrete, reaching Izuku’s sensitive ears. It wasn't the sound of the villain. It was the sound of the manhole cover being completely blown off its hinges, flying into the air and crashing violently against the tunnel wall.

 

A shadow fell over the entrance of the underpass, blocking out the afternoon sun.

 

"It's all right now, young man," a voice boomed.

 

It wasn't a normal voice. It was deep, resonant, and overflowing with an impossible, radiant confidence. It was a voice that Izuku had listened to thousands of times on a crackling computer monitor in his bedroom. It was a voice that promised salvation.

 

The Sludge Villain froze, his liquid form shuddering. "Y-You!"

 

Izuku couldn't turn his head, but through the hazy, fading edge of his vision, he saw the silhouette. The towering, muscular physique. The golden hair standing up like two rabbit ears. The bright, blinding smile that pierced through the darkness of the tunnel like a beacon of absolute hope.

 

"Fear not, kid!" All Might stepped forward, drawing his fist back. The sheer air pressure around him seemed to warp. "For I am here!"

 

All... Might? Izuku's mind whispered, the last reserves of his consciousness clinging to the image.

 

"TEXAS..." All Might roared, lunging forward with a speed that defied the laws of physics. "...SMASH!"

 

The Number One Hero threw a punch into the empty air. He didn't even touch the villain. The sheer, incomprehensible force of the wind pressure generated by the strike hit the Sludge Villain like a solid wall of kinetic energy.

 

The wind tore through the tunnel like a hurricane. The sludge enveloping Izuku’s face and body was instantly violently ripped away, atomized by the gale-force winds. Izuku’s heavy body was pinned to the concrete by the pressure, his scales rattling.

 

The villain shrieked as his liquid body was scattered into a thousand meaningless droplets, splattering against the tunnel walls.

 

The wind died down as quickly as it had erupted. The sudden absence of pressure left a ringing silence in the underpass.

 

Izuku gasped, his powerful lungs expanding as he greedily sucked in oxygen. He coughed, his chest heaving, his claws scraping uselessly against the ground as he tried to push himself up. He was exhausted, his muscles trembling from the lack of oxygen and the sheer terror of the ordeal.

 

Through his watering eyes, he looked up.

 

All Might stood over him, holding a large, plastic soda bottle into which he was rapidly scooping the remains of the Sludge Villain. He sealed the cap tight and tucked it into his cargo pants. Then, the Number One Hero turned and looked down at the teenage boy lying on the concrete.

 

Izuku froze. His breath hitched.

 

Here he was, a terrifying, six-foot-two crocodile monster, lying in the shadows of a sewer tunnel, covered in muck, his fangs bared as he gasped for air. He looked exactly like the villains All Might spent his life putting away.

 

He's going to attack me, Izuku thought, shrinking back, his tail curling protectively around his legs. He's going to think I'm the villain's accomplice. Or just another monster.

 

But All Might didn't raise his fists. He didn't look at Izuku with disgust or fear.

 

Instead, the Symbol of Peace stepped forward, his impossibly wide smile softening just a fraction, and extended a massive, calloused hand toward the terrifying reptilian boy.

 

"Are you alright, my scaly friend?" All Might asked, his voice ringing with genuine, unquestionable kindness. "Apologies for getting you caught up in my villain hunt! But you held out wonderfully!"

 

Izuku stared at the hand. He looked at All Might's face. There was no hesitation. No prejudice. Just a hero checking on a civilian.

 

Slowly, with trembling fingers, Izuku reached out his massive, clawed hand and placed it into All Might’s. The hero effortlessly pulled Izuku’s immense, heavy frame to his feet.

 

"T-Thank you," Izuku rumbled, his gravelly voice thick with emotion. "Y-You saved my life."

 

All Might patted Izuku’s armored shoulder, seemingly unfazed by the rock-hard scales. "It is what heroes do! Now, I must be off! I have to take this sludge-ball to the police!" All Might turned, bending his knees, preparing to leap into the sky.

 

"Wait!" Izuku blurted out.

 

All Might paused, glancing over his shoulder. "Yes?"

 

Izuku’s heart hammered against his ribs. This was it. This was the moment. The man who had defined his entire existence, the man who represented everything Izuku wanted to be, was standing right in front of him. He couldn't let him leave. Not without asking the question that had haunted him for ten long, painful years.

 

Izuku took a step forward. He didn't try to shrink himself this time. He stood at his full, towering height, his tail resting heavily on the concrete. He looked All Might in the eye, his golden, slitted pupils filled with a desperate, burning light.

 

"I have a Quirk," Izuku started, his voice shaking, "but it just makes me look like a monster. People are scared of me. They look at me and they see a villain. They tell me that heroes have to make people feel safe, and that looking like this... that I could never do that."

 

All Might turned fully around, his smile fading slightly as he listened to the raw pain in the giant, terrifying boy's voice.

 

Izuku clenched his clawed fists, tears welling up in his eyes, spilling over his scales and dropping onto the pavement.

 

"Even if I look like a monster..." Izuku cried out, his voice cracking. "Even if everyone is afraid of me... can someone like me ever become a hero who saves people with a smile?!"

 

The wind blew through the tunnel, rustling All Might's golden hair. The Number One Hero stared at the crying beast before him, his blue eyes widening slightly.

 

And somewhere deep within All Might's chest, where a terrible, festering wound lay hidden beneath his clothes, something shifted.

 

Before All Might could open his mouth to answer, a sharp, stabbing pain erupted in his side. A cough forced its way up his throat. He covered his mouth, feeling the warm, metallic tang of blood on his glove.

 

Oh no, All Might thought, feeling the steam begin to rise from his skin. Not now. Not here.

 

Izuku blinked through his tears as a sudden cloud of thick white smoke erupted from the Symbol of Peace, completely obscuring the towering hero from view.

 

"All Might?" Izuku asked, wiping his eyes with the back of his scaly hand.

 

The smoke began to clear, blown away by the gentle afternoon breeze. But the towering, muscular god of heroism was gone. In his place stood a skeletal, emaciated man with hollow cheeks, baggy clothes, and blood trickling down his chin.

 

The skeletal man coughed, wiping the blood from his mouth, and looked up at the terrifying, six-foot crocodile teenager staring down at him in absolute shock.

 

"Well," the skeletal man sighed, his voice completely devoid of its former booming resonance. "This complicates things."

 

The silence in the concrete underpass was absolute, save for the shallow, rattling breaths escaping Izuku Midoriya’s unhinged jaw.

 

A moment ago, the Number One Hero, the towering Symbol of Peace, had been standing before him. Now, wrapped in a dissipating cloud of white steam, stood a man who looked like a walking corpse. He was incredibly tall, but painfully emaciated, his limbs practically skeletal beneath clothes that hung off him like a scarecrow’s rags. His cheekbones jutted out sharply against hollow cheeks, and his eyes were sunken deep into dark, shadowy sockets. A fresh trail of blood trickled off his chin, splashing onto the pavement.

 

Izuku’s golden, slitted pupils dilated until they almost swallowed his irises entirely. His heavy tail, which had been resting on the ground, suddenly stiffened, the thick muscles coiling in pure, unadulterated panic.

 

"W-What?!" Izuku shrieked. Due to his crocodilian vocal cords, the sound wasn't a high-pitched squeak, but a terrifying, guttural roar of confusion that echoed loudly off the concrete walls. He scrambled backward, his heavy claws clicking frantically against the ground. "Where did he go?! Did you eat him?! No, wait, you're wearing his clothes! Are you an imposter?! A villain with a deflation Quirk?! Or... or did I eat him and this is a hallucination?!"

 

"Calm down, kid," the skeletal man sighed, raising a bony hand and wiping the blood from his mouth. His voice was no longer the booming, resonant bass that could shake the heavens; it was a tired, scratchy baritone. "There's no imposter. I am All Might."

 

To prove his point, the man took a deep breath. For a split second, his muscles instantly expanded, his chest puffing out into the familiar, barrel-chested physique of the Number One Hero, accompanied by a booming, "I AM HE—" before a violent cough wracked his frame, accompanied by another spurt of blood, and he deflated back into the frail, skeletal figure.

 

Izuku froze, his massive jaws hanging open in sheer disbelief. "You... you really are him."

 

"I am," Toshinori Yagi groaned, sliding down the curved concrete wall of the underpass until he was sitting on the ground, his long legs stretched out in front of him. "Look, kid. You can't tell anyone about this. You can't post about it online. You can't tell your friends. The Symbol of Peace must always be a fearless, invincible hero. If the world finds out I look like a stiff breeze could break me in half, the criminal underworld would tear society apart."

 

Izuku slowly sank to his knees, sitting carefully on his heavy, armored legs so he could be closer to eye level with the man. He nodded frantically. "I-I won't! I promise, All Might, sir! I won't say a word to anyone! But... how did this happen? You're invincible!"

 

"Nobody is invincible, young man," Toshinori said, a bitter smile touching his lips. He reached for the hem of his oversized white t-shirt and slowly pulled it up.

 

Izuku gasped, his claws instinctively coming up to cover his snout.

 

On the left side of All Might’s chest, taking up a massive portion of his torso, was a horrific, gnarled scar. It looked like a spiderweb of purple and red tissue radiating from a central crater, where the flesh and muscle had simply been obliterated. It was a wound that no normal human should have ever survived.

 

"Five years ago," Toshinori explained softly, his sunken blue eyes staring at the horrific injury. "My respiratory system was nearly destroyed. I lost my entire stomach. After countless surgeries, I was left like this. Right now, I can only do hero work for about three hours a day. The rest of the time... I'm just the husk you see before you."

 

Izuku’s brilliant, analytical mind raced, parsing through years of hero trivia. "Five years ago... was it the fight with Toxic Chainsaw?"

 

"You know your stuff," Toshinori chuckled, pulling his shirt back down. "But no. That punk couldn't land a scratch on me. This fight was kept strictly under wraps. The public never knew." He looked up at Izuku, his expression turning somber and incredibly serious. "I tell you this to show you the reality of the path you are asking about."

 

Izuku stiffened. The question. He had almost forgotten in the shock of the reveal.

 

Even if I look like a monster... can I be a hero who saves people with a smile?

 

Toshinori looked at the boy. Really looked at him. He saw the sheer, monstrous size of the teenager. He saw the thick, impenetrable-looking green scales. He saw the razor-sharp fangs that naturally rested outside of his gums. He saw the slit pupils and the powerful, heavy tail. It was a terrifying physiology. If Toshinori had bumped into this kid in a dark alley without context, he would have assumed he was a mutant-type villain. Society was cruel to those who didn't fit the aesthetic mold of a savior.

 

But Toshinori wasn't going to lie to the boy. Not about this.

 

"Kid... the world of pro heroes is not a comic book," Toshinori began, his voice gentle but firm. "It is a dangerous, lethal profession. You asked me if you could be a hero who saves people with a smile. The smile... the smile isn't just for the cameras. It's a mask. I smile to trick the fear inside me. I smile to hide the pain. When you face down villains who want nothing more than to slaughter you and the people behind you, you have to be ready to put your life on the line. Every single day."

 

Toshinori paused, taking a breath. "And regarding your... appearance. I won't sugarcoat it. Society is shallow. A pro hero needs to inspire hope. When citizens are trapped under rubble, bleeding and terrified, the hero who reaches out to them needs to be a beacon of comfort. If your appearance causes them to hesitate, even for a second, it could cost them their lives. Or yours."

 

Izuku’s heart plummeted. He felt the cold truth of the words sinking into his heavy bones. It was the same thing Bakugo had said, but hearing it from All Might... it was the final, definitive blow.

 

"I cannot, in good conscience, tell you that you can be a hero," Toshinori said gently, closing his eyes. "Not when the public might reject you, and not when the villains will target you. It is a lonely, brutal road. If you want to help people, there are other ways. Become a police officer. They get a lot of grief, but it's an honorable profession. It's not bad to dream, young man... but you have to make sure your dreams are realistic."

 

Silence fell over the underpass, thick and suffocating.

 

Izuku didn't cry. He was too hollowed out for tears. He simply lowered his heavy head. The thick plates of armor on his neck shifted, a low, scraping sound in the quiet space.

 

"I... I understand," Izuku rumbled, his voice devoid of its usual anxious energy. It sounded flat, heavy, and resigned. "Thank you for your honesty, All Might, sir. I... I should go home."

 

Toshinori watched with a pang of guilt as the massive, terrifying boy stood up. For all his monstrous features, the kid looked impossibly small right then. Izuku turned around, his thick tail dragging lifelessly against the concrete, and began the slow, heavy march out of the tunnel.

 

I had to tell him, Toshinori thought, clenching his fists. It's better to crush the dream now than watch him be crushed by the reality of society later.

 

Toshinori stood up, feeling his pocket to make sure the plastic bottle containing the Sludge Villain was still there.

 

His fingers met empty fabric.

 

Toshinori froze. He frantically patted his cargo pants. He checked his front pockets. His back pockets. He looked frantically around the concrete floor of the underpass. Nothing.

 

Then, he remembered the moment he had lunged forward to protect the boy, the moment he had deflected the villain's attack. The sheer wind pressure, the chaotic movement... the bottle must have slipped out.

 

"Oh no," Toshinori whispered, cold dread pooling in his ruined stomach.

 

 

 

Izuku Midoriya walked through the streets of Musutafu like a ghost trapped in a titan's body.

 

The afternoon sun had begun to sink, casting long, fiery orange shadows across the pavement. The city was alive with the sound of commuters heading home, shopkeepers shouting out their evening sales, and the distant hum of traffic. To Izuku, it all sounded like static.

 

He caught his reflection in the glass of a bakery window.

 

He stopped and stared. He didn't see the boy who obsessively took notes on hero tactics. He didn't see the son who loved his mother's Katsudon.

 

He saw a beast. A six-foot-two apex predator. He saw the terrifying spread of his jaw, the deadly glint of his teeth, the cold, reptilian indifference of his golden eyes.

 

“If your appearance causes them to hesitate, even for a second, it could cost them their lives.”

 

All Might was right. Izuku had been lying to himself. He had spent his entire life believing that if he just tried hard enough, if he just smiled wide enough, people would look past the scales and the claws. But they wouldn't. The fear was primal. It was instinct. Just like the instinct that made Izuku’s own tail lash when he felt threatened, normal humans had an instinct to run from things that looked like they belonged at the top of the food chain.

 

"It's over," Izuku whispered to himself, the gravelly resonance of his voice vibrating in his chest. "I'll just... I'll withdraw my U.A. application tomorrow. I'll look into a normal high school. I'll just keep my head down. No more dreaming."

 

He reached a hand up to rub his eyes, careful not to scratch his face with his claws.

 

BOOM.

 

The sound was distant, but Izuku’s highly sensitive ears picked it up instantly. It wasn't the rhythmic thud of a construction site or the backfire of an engine. It was the sharp, concussive shockwave of a detonation.

 

Izuku’s head snapped up. His external auditory canals swiveled. The slits of his pupils widened, absorbing more of the fading light.

 

Then, the smell hit him. His olfactory system, designed to track prey across miles of murky water, picked up the scent carrying on the wind. Burning plastic. Shattered concrete. Ozone.

 

And something else. A sickly, sweet, putrid smell that he had experienced just thirty minutes ago in a dark sewer tunnel.

 

The Sludge Villain? Izuku’s mind raced. But All Might caught him... didn't he?

 

More explosions echoed, followed by the faint, high-pitched wail of sirens.

 

Izuku’s brain told him to turn around. It's not your problem. You're not a hero. You're just a kid with a scary Quirk. Go home. Let the professionals handle it.

 

But his feet were already moving.

 

His digitigrade legs pumped beneath him, the powerful muscles propelling his massive frame forward. His heavy tail lifted off the ground, acting as a counterbalance as he broke into a terrifying sprint. To the pedestrians on the sidewalk, he looked like a runaway freight train covered in scales. People screamed and dove out of his way as he barreled past them, leaving deep, clawed gouges in the asphalt where he pushed off.

 

He didn't care about the stares right now. He had to see. He had to know.

 

Izuku arrived at the Tatooin Shopping District in record time. The scene before him was absolute chaos.

 

A massive fire had broken out, engulfing three different buildings. The heat radiating from the blaze was intense, washing over the gathered crowd. For Izuku, the heat was incredibly uncomfortable. As a cold-blooded mutant, he needed warmth to function optimally, but the dry, searing heat of a blazing fire threatened to dry out his scales and throw his internal thermoregulation into chaos. He could already feel his skin tightening painfully.

 

A large crowd had formed behind a police barricade. Izuku easily saw over their heads, his towering height finally proving useful.

 

In the center of the intersection, surrounded by a ring of fire, was the Sludge Villain. He was massive, twice the size he had been in the tunnel, undulating violently as he destroyed everything around him.

 

But that wasn't the worst part.

 

Pro heroes were on the scene. Death Arms, the strength-enhancing hero, was standing near the fire, looking frustrated. Kamui Woods was retreating, his wooden arms smoking from the heat. Backdraft, the water hero, was desperately trying to keep the flames from spreading to the civilian crowd, leaving him entirely unable to assist in combat. Mt. Lady was standing two streets over, complaining that she didn't have a two-lane road to safely enlarge herself.

 

They weren't fighting. They were waiting.

 

"Why aren't they doing anything?" a civilian nearby muttered.

 

"Look!" another pointed. "The villain has a hostage! He's using some kid's Quirk to keep the heroes at bay!"

 

Izuku’s slitted eyes snapped to the center of the sludge.

 

Trapped within the putrid green mass was a teenager in an Aldera Junior High uniform. The sludge was wrapped completely around his body, leaving only his face exposed. The teenager was thrashing wildly, his hands extended outward, setting off massive, uncontrolled explosions that fueled the fires around them.

 

The hostage's face was contorted in sheer, absolute terror. His ash-blonde hair was plastered to his forehead with sweat and slime. His red eyes were wide, frantic, and desperate.

 

It was Katsuki Bakugo.

 

Izuku’s breath caught in his throat. His entire body froze.

 

Kacchan...

 

"It's no use!" Death Arms shouted over the roar of the flames. "There's no way to get close without getting blown up! And my physical attacks won't work on that liquid body! We have to wait for someone with a suitable Quirk!"

 

"Hang on, kid!" Kamui Woods yelled. "Just hold on a little longer!"

 

Izuku watched as Bakugo struggled. He watched as the sludge began to creep over Bakugo's mouth and nose. He recognized that feeling. The suffocating, terrifying darkness. He knew exactly what Bakugo was experiencing right now. The feeling of absolute helplessness.

 

He's suffocating, Izuku thought. He's going to die.

 

Izuku looked at the pros. They were hesitating. They were waiting for someone else. They were making the tactical, logical choice to preserve their own lives and wait for a better matchup. It was the smart thing to do.

 

But Izuku Midoriya was not smart when it came to saving people.

 

He didn't think about his ruined dreams. He didn't think about All Might's rejection. He didn't think about the fact that Bakugo had literally told him to kill himself earlier that day, or that Bakugo had called him a useless beast for ten years.

 

He only saw a person in pain.

 

And before his conscious mind could even process the command, the beast broke its chains.

 

CRUNCH.

 

Izuku’s clawed feet shattered the asphalt beneath him as he launched himself forward. He burst through the crowd like a cannonball, shoving past the police barricade so fast he was nothing but a blur of dark green scales.

 

"Hey! Kid! Stop!" Death Arms roared, reaching out to grab him, but his fingers slipped off Izuku’s polished, armored shoulder.

 

"Are you crazy?!" Kamui Woods shouted. "Get back here! You'll burn!"

 

Izuku didn't hear them. The roaring of the fire and the blood pounding in his ears drowned out everything else. The intense heat blasted against him, drying out his eyes and making his scales feel like they were warping, but he ignored the pain.

 

He crossed the intersection in three massive strides. The Sludge Villain turned, his bulbous eyes widening in shock.

 

"You?!" the villain gurgled. "The freak from the tunnel! Back for round two?!"

 

Bakugo, tears streaming down his face from the smoke and terror, snapped his eyes toward the approaching figure. Through the haze of his panicked mind, he saw the towering, terrifying silhouette of the crocodile monster charging straight through the flames.

 

"D-Deku...?" Bakugo choked out, right before the sludge forced its way back into his mouth.

 

Izuku didn't slow down. He didn't try to punch the villain—he already knew physical attacks were useless. Instead, he spun on his heel, shifting his massive weight, and whipped his heavy tail around in a devastating arc.

 

THWACK!

 

The massive, armored tail struck the burning debris surrounding the villain. A rusted car door and a chunk of concrete were sent flying like artillery shells, smashing into the Sludge Villain's left eye. The villain shrieked in pain, his liquid body recoiling violently.

 

"You little pest!" the villain roared. He whipped a thick tendril of sludge forward, but Izuku ducked beneath it, his digitigrade legs giving him incredible agility despite his massive bulk.

 

Izuku lunged forward, closing the distance instantly. He reached out with both hands and plunged his massive, clawed arms straight into the putrid green sludge, aiming right for the mass surrounding Bakugo’s face.

 

It's slick... I can't get a grip! Izuku thought in panic as his claws slipped through the liquid.

 

"Get off me!" the villain screamed.

 

Suddenly, Bakugo's palms, trapped within the sludge, ignited. A point-blank, massive explosion detonated right against Izuku’s chest. The concussive blast hit Izuku like a sledgehammer, blowing his head back. The intense heat scorched the pale yellow scales of his underbelly, leaving a smoldering, blackened mark. The deafening BOOM rang in his ears, making his vision swim.

 

A normal person would have been blown to pieces. A normal person would have stopped.

 

Izuku let out a terrifying, guttural roar that shook the very ground beneath them. He forced his head back down, his golden eyes blazing with absolute defiance. He didn't care about the pain. He didn't care about the heat.

 

"I won't let you have him!" Izuku bellowed, his voice sounding like a demon from the depths of the earth.

 

He plunged his hands deeper into the sludge. This time, he didn't try to grab the liquid. He aimed for the source of the villain's eyes and mouth, finding the slightly denser, more solid core of the villain's body. His razor-sharp claws dug in, drawing a sick, squelching sound from the villain.

 

Izuku planted his heavy feet, dug his claws deep into the asphalt for leverage, and pulled.

 

With superhuman strength born of his mutant biology, Izuku physically tore the sludge away from Bakugo's face, prying the villain's liquid jaws open just enough.

 

Bakugo gasped violently, sucking in a massive breath of smoky air. He coughed, his red eyes wide as he stared up at the terrifying face of Izuku Midoriya. Izuku was inches away, his scales scorched, his snout covered in slime, his golden eyes wide and frantic.

 

"Why...?" Bakugo wheezed, his voice breaking. "What the hell are you doing here?! You useless beast... why?!"

 

Tears welled up in Izuku’s slitted eyes. Despite the horrifying arrangement of his seventy-two jagged teeth, despite the monstrous visage that terrified the world, Izuku pulled his lips back in a desperate, trembling smile.

 

"I don't know!" Izuku cried out, his gravelly voice cracking with emotion. "My legs just moved on their own! You... you looked like you were asking for help!"

 

Bakugo’s eyes widened. For a single, frozen moment, the explosions stopped. The roaring of the fire faded. Bakugo didn't see a monster. He didn't see a giant lizard. He saw the crying face of the little boy who had offered him a hand in the dirt all those years ago. He saw a hero.

 

But the moment shattered as the Sludge Villain recovered.

 

"I'll kill you both!" the villain roared, raising two massive tendrils of solid sludge high into the air, preparing to crush them into paste.

 

Izuku couldn't dodge. His claws were buried deep in the sludge, anchoring him in place. He couldn't let go, or Bakugo would suffocate again. Izuku gritted his teeth, shifting his body to cover Bakugo completely, preparing to take the lethal blow with the thickest scales on his back.

 

I guess... this is it, Izuku thought, closing his eyes. I didn't get to be a pro. But... I got to save someone.

 

The blow never connected.

 

A sudden, immense pressure descended upon the intersection. It was a physical weight, a raw manifestation of power that snuffed out the roaring flames in a ten-meter radius.

 

Izuku opened his eyes just as a massive, muscular hand grabbed him by the shoulder and pulled him back with astonishing gentleness.

 

"I really am pathetic," a familiar, booming voice echoed through the silence.

 

Izuku gasped. Standing between him and the towering Sludge Villain was All Might. The Number One Hero was in his muscular form, but blood was actively leaking from the corner of his mouth. His blue eyes burned with a mixture of immense shame and undeniable fury.

 

"All Might?!" the villain screamed, recoiling in terror.

 

"I told you the traits that make a great champion," All Might roared, his voice projecting across the entire city block. He pulled his right arm back, the muscles bulging to impossible proportions. The very air around his fist began to distort and crackle with raw kinetic energy. "But I failed to live up to my own ideals! Pros are always risking their lives! That is the true test of a hero!"

 

All Might stepped forward, twisting his hips, and drove his fist into the air with the force of a falling meteor.

 

"DETROIT..." All Might bellowed, the sound shaking the glass in the surrounding buildings. "...SMASH!"

 

The impact was cataclysmic.

 

All Might's fist didn't hit the villain; it hit the air itself. A localized tornado erupted from the point of impact. The sheer, devastating wind pressure tore through the intersection. The Sludge Villain was instantly ripped to shreds, his liquid form scattering into a fine mist across the pavement. The raging fires on the surrounding buildings were instantly snuffed out, starved of oxygen and blown away by the gale.

 

Izuku, despite his massive weight, was lifted off his feet by the wind. He landed hard on his back, his heavy tail cushioning the blow, sliding across the concrete until he crashed against the police barricade.

 

The wind howled for a few seconds more before slowly dying down.

 

Izuku lay on his back, staring up at the sky. His scales throbbed with heat, and his chest ached from the explosion, but he was alive. He blinked, noticing a strange sensation on his snout.

 

Drip. Drop.

 

He looked up. The sky, which had been clear and orange just moments before, was now dark with fast-moving clouds. Rain began to fall, washing the soot and slime from Izuku’s scales.

 

He... he changed the weather with a single punch, Izuku thought, awestruck.

 

The intersection was completely silent, save for the patter of the newly formed rain. The civilians, the pro heroes, and the police all stared in stunned disbelief. Then, as one, the crowd erupted into deafening cheers.

 

"ALL MIGHT! ALL MIGHT! ALL MIGHT!"

 

The Number One Hero stood tall, his fist raised to the sky, ignoring the blood dripping from his chin as he basked in the cheers.

 

 

 

The aftermath was a blur.

 

The police quickly secured the area, collecting the scattered remains of the Sludge Villain into several secure containers. Paramedics rushed in to treat the wounded.

 

Izuku sat on the back bumper of an ambulance, a thin metallic blanket draped over his massive shoulders. A paramedic was carefully applying a cooling gel to the scorched scales on his chest. Izuku flinched slightly, but thanked the woman politely.

 

He looked across the intersection. Bakugo was surrounded by the pro heroes. Death Arms, Kamui Woods, and Backdraft were all praising him.

 

"That Quirk of yours is incredible!" Death Arms laughed, clapping Bakugo on the back. "The sheer power of those explosions! And your stamina to hold out against a villain like that! You're definitely pro hero material, kid!"

 

Bakugo didn't look happy. He sat on the pavement, glaring at the ground, his red eyes darting occasionally toward the ambulance where Izuku sat.

 

Izuku lowered his head. He knew what was coming next.

 

"Hey, you!"

 

Izuku flinched as Death Arms stomped over to the ambulance. The pro hero looked down at Izuku, his expression a mix of anger and unease. Despite Izuku sitting down, he was nearly eye-level with the burly hero.

 

"What were you thinking, kid?!" Death Arms scolded, pointing a finger at Izuku's snout. "You had no business charging in there! There was absolutely nothing you could have done against a villain with a fluid body! You just endangered yourself and got in our way! If All Might hadn't shown up, you'd be dead! Leave the hero work to the pros, and stop acting like a wild animal!"

 

Kamui Woods walked up behind Death Arms, nodding in agreement. "He's right. Your mutation makes you incredibly resilient, but it doesn't make you invincible. Rushing into a fire like that was reckless and foolish."

 

Izuku didn't argue. He didn't defend himself. He just bowed his heavy head, his golden eyes staring at his clawed hands resting in his lap.

 

"I'm sorry," Izuku rumbled softly. "I... I just wanted to help."

 

The heroes sighed, their anger deflating slightly at the boy's polite and incredibly timid demeanor, completely at odds with his terrifying appearance.

 

"Just... go home, kid," Death Arms said, waving a hand. "Leave this to us."

 

Izuku stood up, wrapping the metallic blanket around his shoulders. He didn't look at Bakugo. He didn't look at the crowd. He just turned and began the long, heavy walk home.

 

The sun had completely set by the time Izuku reached his neighborhood. The streetlights flickered on, casting long shadows across the quiet residential streets. The adrenaline had completely worn off, leaving him exhausted. His scales felt dry and uncomfortable, and his muscles ached.

 

He replayed the day's events in his mind.

 

He had been told by his idol that he couldn't be a hero. He had watched the same idol save the day. He had been scolded for trying to help. It was the definitive proof he needed. He was a monster, not a hero.

 

"I'll have to tell Mom tonight," Izuku whispered to the empty street. "I'll tell her I'm not going to apply to U.A. It'll break her heart... or maybe she'll be relieved."

 

"DEKU!"

 

Izuku stopped dead in his tracks. His auditory canals swiveled backward.

 

He turned around slowly. Standing under the glow of a streetlight, panting heavily from running, was Katsuki Bakugo. The blonde boy looked a mess. His uniform was scorched, his face was covered in soot, and his eyes were blazing with a volatile mix of anger, confusion, and something else Izuku had never seen before.

 

Izuku tensed, his heavy tail curling defensively. He braced himself for the yelling. He braced himself for an explosion.

 

Bakugo marched up to him, stopping just a few feet away from the towering crocodile-boy. Bakugo tilted his head back to look Izuku in the eye.

 

"Listen to me, you giant, ugly freak!" Bakugo yelled, pointing a finger at Izuku's chest. "I didn't ask for your help! You didn't save me! I was doing perfectly fine on my own! You hear me?! I didn't need a useless beast like you pitying me!"

 

Izuku blinked, his slitted eyes widening slightly. He stared at Bakugo.

 

Bakugo was shaking. His hands were clenched into tight fists at his sides. He took a deep, ragged breath, his chest heaving.

 

"You didn't do anything!" Bakugo shouted, his voice cracking slightly at the end. He glared at Izuku for one more agonizing second, then turned on his heel and stomped away down the street, not looking back.

 

Izuku watched him go, completely bewildered.

 

What was that? Izuku thought. Did he run all the way here just to yell at me?

 

Izuku let out a long, rattling sigh. It didn't matter. It was just Kacchan being Kacchan. Izuku turned back toward his house, ready to crawl into his heated room and sleep for a week.

 

"I AM HERE!"

 

Izuku yelped, a terrifying, guttural sound, as All Might suddenly vaulted out of a nearby alleyway, landing in a hero pose right in front of him.

 

"A-All Might?!" Izuku yelled, his tail whipping back and forth in shock. "What are you doing here?! How did you get past the reporters?!"

 

"Hahaha! Standing for interviews is a piece of cake for me!" All Might laughed, flexing his biceps. "But I slipped away because I had to find you! I have a proposal for you, young—"

 

Before he could finish his sentence, the hero dissolved into a cloud of white steam, coughing up a mouthful of blood as he returned to his skeletal form.

 

"Wah! You're bleeding again!" Izuku panicked, reaching his massive hands out as if to catch the man.

 

Toshinori wiped his mouth, sighing heavily. "I'm fine, kid. Honestly, it happens all the time." He straightened up, his sunken blue eyes locking onto Izuku’s golden, slitted gaze. The playful, heroic facade fell away, leaving only intense, profound sincerity.

 

"Young man," Toshinori said, his voice quiet but echoing in the empty street. "I came here to apologize. And to thank you."

 

Izuku blinked, pointing a thick claw at his own chest. "M-Me? Why?"

 

"Earlier today, in the tunnel, I told you to be realistic," Toshinori said, stepping forward. "I looked at you, I saw your mutation, I saw your fear, and I told you that you couldn't be a hero. I let my own cynicism and the shallow rules of society blind me."

 

Toshinori paused, taking a deep breath.

 

"But out there today... among a crowd of civilians, among seasoned pro heroes who stood by and did nothing..." Toshinori looked up, his eyes shining with unshed tears. "You were the only one who moved. You, a boy who has been told his whole life that he is a monster, a boy who possesses a Quirk completely unsuited for rescuing hostages... you were the only one who risked everything to save a life."

 

Izuku’s breath caught in his throat. His heavy tail stopped moving. He stared at the skeletal man, unable to comprehend what he was hearing.

 

"You taught me something today," Toshinori continued, placing a bony hand over his heart. "Top heroes all have stories about their school days. Most of their stories have one thing in common. Their bodies moved before they had a chance to think."

 

Izuku gasped. Tears instantly welled up in his slitted eyes, blurring his vision. He remembered the feeling. The sheer, terrifying lack of control as his legs propelled him into the fire.

 

"That was true for you today, wasn't it?" Toshinori asked, a gentle smile gracing his hollow face.

 

Izuku couldn't speak. He squeezed his eyes shut, nodding frantically.

 

"You can become a hero."

 

The words hit Izuku like a physical blow. The impenetrable scales, the terrifying fangs, the years of bullying, the terrified screams of children... all of it seemed to shatter in that single moment.

 

Izuku Midoriya, the six-foot-two crocodile-human hybrid, fell to his knees on the asphalt. He clamped his massive hands over his snout and began to sob. It wasn't a quiet cry. It was a deep, guttural, rattling wail of pure, unadulterated release. He cried for the little boy who just wanted to help. He cried for the teenager who thought he was a monster.

 

Toshinori stood there, letting the boy cry. He waited until Izuku’s sobs subsided into quiet, rattling hiccups.

 

"You are worthy," Toshinori said softly, looking down at the giant, weeping boy. "You have the heart of a true hero. And because of that, I have decided. I am going to pass my Quirk onto you."

 

Izuku froze. He slowly lowered his hands, looking up at Toshinori through tear-streaked, golden eyes.

 

"P-Pass it on...?" Izuku rumbled, his voice thick with confusion. "But... Quirks are genetic. They're biological. You can't just pass them on like a torch."

 

"That is true for most Quirks," Toshinori grinned, a spark of the old Symbol of Peace returning to his eyes. "But mine is different. My Quirk was passed down to me like a sacred torch. Its name... is One For All."

 

"One... For All?" Izuku whispered.

 

"Yes," Toshinori nodded, clenching his fist. "It is a power cultivated by one person, passed to another, who cultivates it and passes it on again. It is the crystallization of power, spun together by the voices of those who cry out for help. And I want you to be its next vessel."

 

Izuku stared at him. He looked down at his own massive, clawed hands. He thought about the sheer, destructive power he already possessed. The superhuman strength, the impenetrable armor. If he added the power of All Might on top of that...

 

"Why me?" Izuku asked softly. "I look like a villain. Even today, the heroes scolded me. They told me to stop acting like an animal."

 

"Because they don't see what I see," Toshinori said firmly, stepping forward and placing a hand on Izuku's heavy, scaled shoulder. "They see a beast. I see a boy with a heart so big it couldn't be contained by a normal human body. You have the spirit of a true hero, young Midoriya. I don't care if you have scales, or fangs, or a tail. The world needs heroes who care. And I believe that you can show them that true heroism isn't about what you look like... it's about what you do."

 

Izuku looked up. He looked at the skeletal man who held the power of a god, offering it to a monster.

 

Izuku wiped the tears from his snout. He stood up, towering over the frail hero. He planted his digitigrade feet firmly on the ground, his heavy tail resting proudly behind him. He looked Toshinori Yagi in the eye, and for the first time in his life, he didn't try to hide his teeth.

 

He pulled his lips back, revealing all seventy-two jagged fangs, and smiled. It was terrifying, monstrous, and absolutely beautiful.

 

"I accept."

 

The sea breeze whipping off the coast of Musutafu was usually a pleasant, refreshing thing, carrying the scent of salt and freedom. However, at Dagobah Municipal Beach Park, the wind carried the stench of rotting kelp, rusted iron, decaying rubber, and the stagnant, sickly odor of abandoned appliances.

 

Izuku Midoriya stood at the top of the concrete stairs overlooking the beach, his massive frame silhouetted against the early morning sun. His heavy tail shifted behind him, the thick scutes—the armored scales running down his spine—scraping against the metal railing.

 

He stared down at the shoreline. Or rather, where the shoreline was supposed to be.

 

Mountains of garbage stretched out as far as the eye could see. Broken refrigerators, rusted car chassis, shattered televisions, and mountains of rotting household waste were piled so high they formed artificial valleys and peaks. It didn't look like a beach. It looked like a graveyard for the forgotten refuse of a society that consumed too much and cared too little.

 

"Pretty awful, isn't it?"

 

Izuku turned his head. His nictitating membranes—the translucent second eyelids that protected his eyes underwater—flicked across his golden irises to block the blowing sand. Standing beside him in his skeletal, baggy-clothed form was Toshinori Yagi.

 

"It's... overwhelming," Izuku rumbled, his gravelly voice dropping an octave as his slitted eyes scanned the horizon. "This used to be a beautiful park. I remember reading that the ocean currents in this bay create a natural funnel. Over the years, people realized they could illegally dump their trash here and the tide would just bury it or push it back up the shore. It's an environmental disaster. The local ecosystem..." Izuku caught himself muttering, his claws clicking nervously against the railing. "S-Sorry, All Might, sir. I was rambling."

 

"No, no, you're exactly right!" Toshinori smiled, leaning against the rail. "It is an environmental disaster. And it is the perfect place for you to begin your journey."

 

Izuku blinked, tilting his heavy, crocodilian snout. "My journey... to inherit your Quirk, you mean?"

 

Toshinori turned to fully face the monstrous teenager. The wind fluttered the skeletal man’s oversized white t-shirt, giving him a fragile, ghost-like appearance. But when he spoke, the gravity in his voice anchored him to the earth like solid iron.

 

"Young Midoriya, last night I told you about One For All. But I didn't tell you the physical toll it takes on the human body." Toshinori pointed a bony finger at Izuku’s broad chest. "One For All is the culmination of raw, unadulterated physical power passed down through eight generations. It is a torrent of kinetic energy. If I were to give it to an unprepared, normal human teenager right now... their limbs would literally blow off. Their bones would turn to dust under the sheer pressure of the Quirk."

 

Izuku gasped, his claws instinctively coming up to grip his own arms.

 

"However," Toshinori said, a grin breaking across his hollow cheeks, "you are not a normal human teenager."

 

Toshinori pulled out a small notepad from his pocket. "I did some research on your specific mutation classification last night. 'Apex Reptile.' The biological specs recorded in your public medical file are... frankly, astounding."

 

Toshinori flipped a page. "Your bone density is nearly five times that of an average human. Your skin is composed of heavily keratinized scales reinforced by osteoderms—bony plates that essentially act as natural Kevlar. You possess a bite force exceeding three thousand PSI. Your tail alone is a mass of pure muscle that can shatter concrete. Simply put, Young Midoriya, your body is a fortress."

 

Izuku looked down at his thick, green-scaled hands. For his entire life, these hands had been a source of shame. They were the hands of a monster, hands that made children cry and adults cross the street. But hearing All Might—the greatest hero in the world—analyze his body not as a monstrous deformity, but as a biological marvel... it sparked a tiny, warm ember in Izuku’s chest.

 

"Because your body is already built to withstand immense physical stress," Toshinori explained, tucking the notepad away, "I don't need to worry about One For All tearing you apart the way it would a normal kid. Your skeletal structure can absolutely handle the recoil of the power."

 

"Then... I can take it right now?" Izuku asked, his tail wagging slightly behind him—a canine-like habit he had never been able to suppress, much to his embarrassment.

 

"Ah!" Toshinori held up a finger. "Not so fast! Your body is strong, yes. You have incredible raw burst power. But your Quirk has massive, glaring weaknesses that we must address before you take the entrance exam."

 

Izuku’s tail stopped. He knew his weaknesses all too well.

 

"You are an ectotherm, Young Midoriya. Cold-blooded," Toshinori stated, his tone shifting into that of a strict teacher. "Your body does not generate its own internal heat effectively. In warm environments, you're a powerhouse. But when the temperature drops, your metabolism crashes. You become sluggish, your reaction times plummet, and your stamina is completely nonexistent. Furthermore, because your body relies on sheer burst strength—like a crocodile ambushing prey—you lack sustained endurance. A hero cannot afford to gas out after a five-minute fight. If you activate One For All while your muscles are stiff and cold, even your thick bones will snap under the strain."

 

Toshinori pointed dramatically down at the sprawling mountains of trash.

 

"That is why you are going to clean this beach. Every single piece of trash, from the rusted-out pickup trucks to the smallest soda can. You are going to haul it off this sand and restore this coastline."

 

Izuku stared at the staggering amount of garbage. "I... I'm going to move all of it? By myself?"

 

"Exactly!" Toshinori laughed. "But simply moving it isn't enough. Because of your incredible base strength, hauling a refrigerator in the middle of a sunny afternoon would be too easy for you. It wouldn't push your limits. Therefore, we are going to exploit your weakness to force your body to evolve."

 

Toshinori stepped closer, his blue eyes gleaming with an intense, challenging light.

 

"You will only clean this beach at night. And in the early hours of the morning. When the sun is down, when the sea breeze is freezing, and when your cold-blooded biology is begging you to lie down and sleep. You are going to force your body to work in its most vulnerable state. Over the next ten months, we are going to forge your stamina and push your thermal endurance to the absolute brink."

 

Izuku swallowed hard. The thought of being out here in the freezing wind, performing grueling physical labor when his body naturally demanded hibernation, sounded like pure torture.

 

He looked down at his clawed hands again. He remembered Bakugo suffocating in the sludge. He remembered the feeling of absolute helplessness. He remembered the promise he made to himself when he accepted All Might's offer.

 

Izuku’s massive jaw set. He clamped his seventy-two teeth together, the muscles in his thick neck bulging.

 

"I'll do it," Izuku rumbled, his golden eyes locking onto Toshinori's. "I'll clear the whole beach. I'll make it pristine."

 

Toshinori smiled, a genuine, warm expression that smoothed the harsh lines of his skeletal face. "I know you will, kid. Now, get to school. Your hell begins tonight."

 

 

 

The first night at Dagobah Swamp—as Izuku had taken to calling it in his head—was a lesson in agony.

 

It was mid-April. During the day, the temperature was a pleasant twenty degrees Celsius. But by 2:00 AM, the temperature plummeted to a brisk nine degrees. For a normal human, it was chilly, requiring a sweater. For a crocodilian mutant like Izuku, it was crippling.

 

Izuku stood at the edge of the water, wearing heavily modified sweatpants and a massive, custom-cut tank top. The freezing ocean mist blew directly onto his exposed green scales.

 

Inside his body, millions of years of reptilian evolution were screaming at him to stop. His heart rate slowed to a crawl. The blood vessels near his skin constricted to preserve core heat, leaving his limbs feeling like they were packed tightly with freezing, wet sand. Every movement required immense, conscious effort. Just lifting his heavy tail off the sand felt like he was dragging a boulder attached to his spine.

 

"Alright, Young Midoriya!" All Might boomed. He was in his muscular form, sitting comfortably atop a rusted, overturned pickup truck, wrapped in a thick winter coat. "Let's start with that double-door refrigerator over there! I want you to drag it up the stairs and into the designated disposal truck! No stopping!"

 

Izuku stared at the fridge. It was half-buried in the wet, packed sand, covered in rust and barnacles.

 

Under normal, warm conditions, Izuku could have wrapped his arms around the appliance and lifted it over his head with a grunt. But right now, his body felt completely alien.

 

He shuffled forward, his digitigrade legs shaking slightly. He reached out with his massive, clawed hands and gripped the sides of the fridge. His claws easily pierced the rusted metal, giving him a solid grip.

 

Okay, Izuku thought, his breath pluming in the cold air. Lift.

 

He pulled.

 

Nothing happened.

 

His muscles, usually so explosive and responsive, refused to fire at full capacity. The cold had seeped into his joints, making his ligaments feel as brittle as dry twigs. He groaned, a deep, rattling sound in his chest, and dug his clawed feet deeper into the sand for leverage.

 

"Come on!" Izuku hissed, squeezing his eyes shut as he strained.

 

The metal of the fridge groaned. It shifted an inch.

 

"Don't just use your arms, kid!" All Might called out. "Your core strength is phenomenal because of your tail! Use it! Anchor yourself and pull with your entire body!"

 

Izuku adjusted his stance. He dropped his heavy tail onto the sand, using it as a solid, muscular anchor point like a third leg. He leaned back, channeling the pulling force through his digitigrade legs, up through his thick hips, and into his broad back.

 

With a sickening schhhhck, the refrigerator broke free from the wet sand.

 

Izuku dragged it. One agonizing step at a time. The cold air burned his lungs. His golden, slitted eyes were half-closed as his brain fought the overwhelming biological urge to shut down and enter torpor.

 

It's so heavy, Izuku thought, his teeth grinding together. It's not just the fridge. It's my own body. I'm fighting my own body.

 

He dragged the rusted appliance across twenty yards of sand, then hauled it up the concrete steps. By the time he deposited it into the back of the rented disposal truck, he was gasping for air. He collapsed onto the pavement, his heavy chest heaving. His scales felt like blocks of ice.

 

All Might dropped down beside him, instantly returning to his skeletal form, shivering slightly in his coat.

 

"Excellent work for a first attempt," Toshinori said, handing Izuku a massive thermal thermos filled with boiling hot tea. "Drink this. It will raise your core temperature slightly. Then, get back down there. You have three more hours before you need to go home and get ready for school."

 

Izuku took the thermos with trembling claws. He uncapped it and poured the near-boiling liquid directly down his throat. His crocodilian biology allowed him to consume incredibly hot food without burning his mouth. The heat radiated outward from his stomach, offering a momentary, blessed relief from the freezing lethargy.

 

He didn't complain. He didn't ask for a break. He screwed the cap back on the thermos, forced himself to his feet, and marched heavily back down the stairs into the mountains of trash.

 

 

 

By the end of the first month, Izuku’s life had settled into an exhausting, brutal routine.

 

His alarm would go off at midnight. He would sneak out of the apartment, navigating the quiet streets of Musutafu to Dagobah Beach. From 1:00 AM to 5:00 AM, he hauled trash in the freezing dark. Tires, washing machines, rusted iron girders, waterlogged couches. He dragged them all, fighting his cold-blooded lethargy every single second.

 

He would return home at 5:30 AM, shower off the grime and the smell of the ocean, and eat breakfast.

 

And oh, the breakfasts.

 

His mother, Inko, had noticed the sudden change in her son's appetite. Izuku had always eaten a lot of meat, but now, his caloric intake had skyrocketed to terrifying levels. To fuel his massive, evolving muscles and repair the tissue broken down by his intense labor, his body demanded protein.

 

One morning in late May, Inko stood at the kitchen stove, using her telekinesis to flip six massive steaks simultaneously, while two whole chickens roasted in the oven.

 

"Izuku, sweetie," Inko said, her brow furrowed with concern as she floated the mountain of meat onto his reinforced dining plate. "Are you sure you're feeling alright? You've been coming home exhausted, and you're eating enough to feed a pride of lions. Are... are you having a growth spurt?"

 

Izuku, sitting at the table with dark, heavy bags under his golden eyes, tiredly reached for a steak. He didn't bother with a fork. He grabbed it with his claws, tilted his head back, and swallowed the entire piece of meat in three massive, crunching bites.

 

"Y-Yeah, Mom," Izuku rumbled, his voice even rougher than usual from exhaustion. "Just... working out. Trying to get in shape for the high school entrance exams."

 

"Well, just don't push yourself too hard," she fretted, pouring him a massive glass of milk. "And if you need more food, just tell me. The butcher at the market was so happy to see me yesterday he practically threw in a side of beef for free."

 

After breakfast, it was time for school.

 

Aldera Junior High was its own kind of torture. While his peers paid attention to the teachers, Izuku spent every ounce of his remaining willpower just trying to keep his massive eyes open. The warmth of the afternoon classroom was intoxicating. His cold-blooded biology, starved of sleep and desperate for heat, practically begged him to pass out on his desk.

 

Often, he couldn't help it. His heavy head would slip off his hand, and he would crash face-first onto his desk, the sound echoing like a dropped bowling ball.

 

"Midoriya!" the math teacher would snap. "Are you sleeping in my class?"

 

"N-No, sir!" Izuku would jolt awake, his heavy tail thumping against the floor in panic. "S-Sorry, sir!"

 

From a few rows ahead, Katsuki Bakugo watched the massive, green-scaled mutant through narrowed red eyes.

 

Bakugo wasn't stupid. He noticed the changes. Deku was always a giant, but recently, he seemed... different. The sheer bulk of the monster was changing. The pale yellow scales on his chest looked tighter, revealing the outline of monstrous, dense muscle underneath. The dark green scutes on his back and tail were losing their dull, dry appearance, taking on a polished, armored sheen.

 

But it wasn't just the physical changes. It was the eyes.

 

For ten years, Deku had walked around with his head down. Whenever Bakugo glared at him, those terrifying, slitted golden eyes would instantly avert, filled with timid fear.

 

But one afternoon, as the bell rang, Bakugo kicked Deku’s desk as he walked past.

 

"Watch it, lizard," Bakugo sneered, waiting for the usual stammered apology.

 

Izuku slowly looked up. He didn't flinch. He didn't shrink back. The exhaustion in his slitted eyes was overpowered by a quiet, burning intensity. It was the look of a predator that was finally beginning to understand its own strength.

 

"Sorry, Kacchan," Izuku rumbled softly, not breaking eye contact.

 

Bakugo felt a strange, cold prickle run down his spine. He scoffed, turning away and shoving his hands into his pockets. What the hell is he doing? Bakugo thought, his teeth grinding. He's up to something. A useless beast like him shouldn't have eyes like that.

 

 

 

Month four arrived, bringing with it the sweltering heat of late summer.

 

For Izuku, the heat wave was a blessing and a curse. At night, the temperature was finally warm enough that his body didn't feel like it was moving through wet cement. He could haul two, sometimes three appliances at a time, his monstrous strength fully unlocked.

 

But the heat also brought the smell. The mountains of garbage at Dagobah Beach baked under the summer sun, turning the area into a putrid, rotting sauna.

 

It was during this time that Toshinori introduced the next phase of training.

 

"Your raw strength is improving, Young Midoriya," Toshinori said, watching as Izuku effortlessly crushed a rusted car chassis into a compact cube using his massive arms and chest. "But hero work isn't just about moving heavy objects. It's about agility, balance, and combat."

 

Toshinori pulled out a heavy medicine ball. "Your tail. It accounts for a massive portion of your body weight. You use it wonderfully as a counterbalance, but right now, it's just dead weight dragging behind you. A true Apex Reptile uses every part of its body."

 

Toshinori threw the heavy medicine ball directly at Izuku's face.

 

Izuku gasped, raising his arms to block. But Toshinori was incredibly fast, even in his skeletal form. He darted around Izuku, kicking the back of Izuku’s digitigrade leg, forcing the heavy teenager off balance.

 

"Don't just rely on your armor to take hits!" Toshinori barked. "Move! Adapt! Your tail is a muscle! Control it!"

 

For the next three months, alongside the heavy lifting, Izuku underwent brutal agility training. Toshinori would set up obstacle courses through the labyrinth of garbage. Izuku had to sprint through them without knocking over the carefully balanced towers of trash.

 

At first, he failed miserably. His massive shoulders would clip a television set, or his heavy tail would swing wide, crashing into a pile of tires and bringing the whole thing down.

 

But Izuku’s analytical mind, the mind that had spent years studying the fluid movements of heroes like Kamui Woods and Mirko, began to synchronize with his monstrous body.

 

He learned to shift his weight. He learned to swing his heavy tail left when he needed to make a sharp pivot right, using the immense momentum to turn his six-foot-two frame on a dime. He learned to run not just on his padded feet, but to drop onto all fours when he needed sudden bursts of explosive speed, his claws digging deep into the sand, turning him into a terrifying, quadrupedal missile.

 

He learned the Death Roll.

 

"If an opponent is too strong to strike," Toshinori instructed one night, holding up a massive, waterlogged wooden beam. "You must disorient them. Take their balance."

 

Izuku lunged forward. Instead of punching the beam, he grabbed it with his massive, clawed hands, wrapped his heavy, armored legs around it, and violently twisted his entire body in a rapid, 360-degree spin. The torque generated by his heavy tail and powerful core was catastrophic. The thick wooden beam violently snapped in half under the immense rotational force.

 

Toshinori watched in awe. His combat potential... it's completely different from mine. I relied on overwhelming striking power. But his body is built for grappling, crushing, and raw, feral takedowns. When he inherits One For All... he won't be a copy of me. He will be something entirely new.

 

 

 

Then came winter.

 

Month eight. January.

 

It was the ultimate, brutal test of Izuku’s ten-month journey. A massive cold front moved across Japan, bringing freezing winds and heavy snowfall to the coast of Musutafu.

 

Dagobah Beach was transformed into a frozen, jagged wasteland. The mountains of trash were coated in ice. The ocean water lapping at the shore was a dark, freezing slush.

 

At 2:00 AM, the temperature was a bone-chilling negative four degrees Celsius.

 

Toshinori sat in the heated cab of the disposal truck, his skeletal hands wrapped around a thermos of coffee, watching the beach with immense, gnawing worry.

 

Down on the sand, amidst a blinding flurry of snow, a massive green silhouette was moving.

 

It was Izuku.

 

He was bare-chested. The thick, pale yellow scales on his stomach and the dark green scutes on his back were exposed to the blizzard. He was attempting to push a rusted, gutted city bus across the frozen sand.

 

It was absolute, torturous agony.

 

Izuku’s biological systems were in full crisis mode. His blood was so cold it felt like liquid nitrogen pumping through his veins. His respiratory rate had plummeted. His nictitating membranes were permanently drawn across his eyes to keep them from freezing, turning his vision into a milky, blurry haze. Every single instinct burned into his DNA screamed at him to dig a hole in the sand, curl up, and wait for spring.

 

Push, Izuku’s mind commanded.

 

His massive, clawed hands were pressed flat against the back of the bus. His digitigrade legs, thick with newly forged muscle, trembled violently against the icy sand.

 

He pushed. The bus groaned, its rusted axles squealing. It moved two inches.

 

Izuku fell to his knees, his heavy tail slamming onto the frozen ground. He gasped, his breath creating massive clouds of steam in the freezing air. He couldn't feel his claws. He couldn't feel his snout. The lethargy was so heavy it felt like he was drowning in the deep ocean.

 

I can't, the primal, reptilian part of his brain whispered. It's too cold. Sleep. Just sleep.

 

"Midoriya!"

 

The voice cut through the howling wind. Izuku slowly turned his massive head.

 

Toshinori had stepped out of the heated truck. He was standing on the concrete stairs, the blizzard whipping around his frail, skeletal body. He wasn't wearing his heavy coat. He had taken it off, standing in only his baggy white t-shirt, shivering violently.

 

"I am standing out here with you!" Toshinori roared, his voice cracking from the cold and his own internal injuries. "If you quit, I freeze! If you push, you win! Show me! Show me the heart that moved before it had a chance to think!"

 

Izuku stared at the frail hero. All Might, his idol, the man missing half his respiratory system, was standing in a blizzard just to share in his suffering.

 

Something snapped inside Izuku.

 

It wasn't a biological shift. It was a spiritual one. The human heart inside the monster’s body roared to life, burning with a fire so intense it chased away the freezing lethargy in his blood.

 

Izuku planted his heavy, clawed hands on the icy sand and pushed himself back up. He tilted his massive head back, the snow melting against his warm breath, and let out a roar.

 

It was a sound that belonged in a prehistoric era. A deep, earth-shaking bellow that vibrated the rusted metal of the trash piles and echoed over the roaring ocean.

 

He slammed his hands back onto the bus. He didn't just use his arms or his legs. He used every ounce of willpower, every single shred of the monstrous strength he had cultivated over the last eight months. He ignored the cold. He ignored the pain.

 

I am not a beast, Izuku thought, his golden eyes blazing through the milky membranes. I am a hero!

 

The bus lurched forward.

 

Izuku didn't stop. He pushed it, his massive legs driving like pistons, his heavy tail providing immense, stabilizing force. He pushed the massive vehicle across twenty yards of frozen sand, right to the ramp of the disposal area, before finally collapsing, steam rolling off his heated, muscular body.

 

Toshinori ran down the stairs, throwing the heavy winter coat over the boy’s massive, trembling shoulders.

 

"You did it, kid," Toshinori whispered, tears freezing on his hollow cheeks. "You surpassed your own biology. You did it."

 

Underneath the coat, Izuku pulled his lips back into a terrifying, jagged smile.

 

 

 

Ten months.

 

It was the morning of the U.A. High School Entrance Exam.

 

The sun rose over the ocean, casting a brilliant, golden light across the waters of Musutafu Bay. The tide rolled in, the waves gently lapping against the shore.

 

The beach was beautiful. It was pristine.

 

Not a single tire. Not a single piece of rusted metal. The mountains of garbage were completely, utterly gone, replaced by miles of smooth, glittering sand.

 

Standing at the edge of the water was a titan.

 

Izuku Midoriya let out a long, rattling breath, stretching his massive arms high above his head. The physical transformation he had undergone over the last ten months was staggering.

 

He hadn't grown taller—six-foot-two was towering enough for a fifteen-year-old—but he had grown denser. The bulky, somewhat soft mass of his mutant body had been completely chiseled away, replaced by lean, terrifyingly thick cords of muscle.

 

His dark green scutes were no longer dry and dusty; they shone like polished armor, hard enough to deflect high-caliber gunfire. The pale yellow scales on his chest and stomach rippled over an eight-pack of immense core muscle. His digitigrade legs looked like they were carved from stone, capable of launching his heavy frame incredible distances. His tail, once a dragging, heavy burden, now hovered naturally above the ground, a thick, whip-like appendage of pure, coiled power.

 

Even his face looked different. The soft, somewhat chubby contours of his snout had hardened, his jawline sharp and terrifying. His seventy-two teeth gleamed, razor-sharp.

 

He was the absolute pinnacle of his mutant biology. An Apex Reptile in every sense of the word.

 

"Oh my... oh my... GOODNESS!"

 

Izuku turned. Toshinori was standing on the sea wall in his muscular, All Might form, his hands gripping the railing, his eyes wide with absolute astonishment.

 

"You didn't just finish the designated area," All Might boomed, leaping down from the wall and landing on the sand with a heavy thud. "You cleared the entire shoreline! You overachieved, Young Midoriya! Look at you! You look like a professional hero already!"

 

Izuku chuckled, a deep, rattling sound. He rubbed the back of his neck, his thick claws clicking against his scales. "I-I guess I just got in the zone, All Might, sir. Once the winter broke, it got a lot easier."

 

All Might stepped forward, his massive hand resting on Izuku’s armored shoulder. He looked at the boy with a pride so profound it made his chest ache.

 

"You conquered your weaknesses," All Might said softly. "You built your stamina, you learned combat mobility, and you proved that your spirit cannot be frozen by the cold or crushed by despair. You are an empty vessel no longer. You are a fortress, ready to hold the power of the gods."

 

All Might reached up to his head and casually plucked a single strand of bright golden hair.

 

He held it out to Izuku.

 

"This is it, Young Midoriya," All Might declared, his smile radiant. "The culmination of your suffering and your hard work. Eat this."

 

Izuku stared at the single strand of hair. He blinked his golden, slitted eyes. "Eat... your hair?"

 

"Yes!" All Might laughed. "To inherit One For All, you must consume a piece of my DNA! It doesn't matter what it is, but a hair is the most hygienic! Now, eat up! You have a shower to catch before the exam!"

 

Izuku took the hair with two massive, clawed fingers. He looked at it, then looked at his own terrifying jaws.

 

"Well," Izuku muttered. "I guess my digestion is pretty strong."

 

He popped the hair into his mouth. He didn't even try to chew it with his jagged fangs; he just swallowed.

 

Almost immediately, his stomach let out a loud, terrifying growl that sounded like a revving motorcycle engine. Because crocodilians possessed highly acidic stomachs capable of dissolving entire hooves, horns, and bones within hours, the hair was broken down and assimilated into his bloodstream almost instantaneously.

 

"I... I swallowed it," Izuku said, rubbing his pale yellow stomach. "I don't feel any different."

 

"It will take a few hours for the Quirk factor to fully integrate with your own mutated DNA," All Might explained, returning to his skeletal form as his time limit expired. "You probably won't feel it until the exact moment you need it. Which means during the exam today, you must rely on your own physical strength until the absolute last second. Only use it if you have to. Understand?"

 

Izuku nodded, his heavy tail swishing in anticipation. "Yes, sir."

 

"Then go, Young Midoriya," Toshinori said, pointing toward the city. "Go and show the world the hero you have become."

 

Izuku bowed deeply, turned, and sprinted toward home. His heavy footsteps pounded against the pavement, but they were no longer the clumsy, dragging steps of a boy trying to hide. They were the rhythmic, powerful strides of a beast marching toward its destiny.

 

 

 

When Izuku stepped out of his bedroom, dressed in his customized Aldera Junior High uniform, Inko Midoriya dropped the spatula she was holding.

 

She stared at her son. He completely filled the hallway. His broad shoulders practically brushed both walls. The uniform strained over his massive chest, and the custom trousers could barely contain the thick muscles of his legs and tail. He didn't just look healthy; he looked like a mythical creature.

 

"I-Izuku," Inko gasped, bringing her hands to her mouth. "You... you look..."

 

Izuku stopped, his golden eyes shrinking in anxiety. He thought she was going to say 'terrifying'. He thought she was going to say 'monstrous'.

 

"You look amazing," Inko finished, tears welling in her eyes. "You're so strong, sweetie."

 

Izuku’s slitted eyes widened. He pulled his lips back, showing his teeth in a wide, genuine, terrifying smile. "Thanks, Mom. I have to go! I can't be late for the U.A. exam!"

 

He grabbed his yellow backpack, which looked comically small against his massive back, and rushed out the door.

 

As he jogged toward the train station, the morning sun beat down on him. His cold-blooded biology, fueled by ten months of hellish adaptation, greedily soaked in the warmth, turning it into explosive, boundless energy.

 

He didn't hunch over today. He didn't try to make himself look smaller. He walked tall, his heavy tail swishing proudly behind him, his armored chest puffed out.

 

People still stared. Mothers still pulled their children closer. Whispers still hissed from the alleyways.

 

Look at that monster.

What a terrifying Quirk.

He looks like a villain.

 

But today, Izuku didn't let the words pierce his scales. He just smiled his toothy, jagged smile, and kept walking.

 

He arrived at the towering, glass gates of U.A. High School. The sheer scale of the institution was breathtaking. Thousands of hopeful students were funneling into the main building, chatting excitedly.

 

Izuku stopped at the edge of the courtyard. He looked down at a decorative fountain near the entrance. In the clear water, he saw his reflection.

 

The green scutes. The slitted eyes. The seventy-two teeth.

 

He was a monster. There was no changing that.

 

But suddenly, deep within his chest, a strange, warm sensation blossomed. It wasn't the heat of the sun. It was a spark. A tiny, crackling ember of immense, ancient, kinetic power. It flared for only a microsecond, a flash of red lightning dancing across his green scales, before settling deep into his dense bones.

 

Izuku’s golden eyes widened. He clenched his clawed fist.

 

One For All, he thought, his heart hammering against his ribs.

 

He looked back at the imposing doors of U.A. High School.

 

"I'm ready," Izuku rumbled, his deep voice carrying over the chatter of the crowd.

 

The Apex Reptile stepped through the gates, ready to conquer the world.
