What if deku was The Reincarnation of pickle from baki

 

The world is fundamentally unfair. It is a harsh, unyielding truth that humanity has tried to pave over with concrete, laws, and the glittering smiles of costumed heroes. But beneath the neon lights of the modern age, the ancient laws of nature still pulse. The strong devour the weak. The apex predator claims the highest peak.

 

Eighty percent of the global population possessed a "Quirk," a unique genetic mutation that granted them abilities ranging from the mundane to the godlike. With the dawn of Quirks, society believed it had taken the ultimate step forward in evolution. They believed they had conquered nature, ascending beyond the primal struggles of survival.

 

They were wrong.

 

Nature has a long memory. And sometimes, when the present becomes too arrogant, the past awakens to remind the world what true, unfiltered power looks like.

 

For Izuku Midoriya, the awakening did not begin with a burst of fire, nor did it manifest as the ability to pull objects through the air. It began with a fever. A fever so violent, so terrifying, that it felt as though his small, fragile, four-year-old body was trying to burn away the present to make room for the past.

 

 

 

 

Inko Midoriya sat by her son’s bedside, her eyes red and puffy from crying. The small apartment in Musutafu was usually filled with the cheerful, albeit obsessive, muttering of her son as he watched endless videos of the Pro Hero All Might. But for the last three days, the apartment had been consumed by an unnatural, suffocating heat emanating from Izuku’s bedroom.

 

"Mommy..." Izuku whimpered, his voice raspy.

 

Inko quickly wet a washcloth in a bowl of ice water, wringing it out before gently pressing it to his forehead. The water sizzled slightly, turning to steam upon contact with his skin. She gasped, pulling her hand back.

 

"I'm here, Izuku. Mommy’s here," she whispered, her voice trembling. "Hold on, baby. The doctor said the Quirk manifestation fevers can be intense, but... this..."

 

This was beyond intense. Izuku was changing, and Inko could only watch in horrified fascination as her little boy’s body practically warped beneath the thin bedsheets.

 

It started with his bones. The sound of it would haunt Inko’s nightmares for years to come—a deep, resonant cracking and shifting, like tectonic plates grinding against one another deep beneath the earth. Izuku didn't scream, which was almost worse. He merely gritted his teeth, letting out low, rumbling groans that vibrated in Inko's chest.

 

Over the course of seventy-two hours, Inko watched her son outgrow his pajamas, and then his bed.

 

By the morning of the fourth day, the fever broke.

 

Inko, who had fallen asleep in the chair beside his bed, was jolted awake by the sound of heavy, rhythmic breathing. It didn't sound like a child. It sounded like a massive bellows drawing in air.

 

She blinked the sleep from her eyes, the morning sunlight filtering through the curtains, and looked toward the bed. The frame was bowed inward, the mattress groaning under an impossible weight.

 

"Izuku?" she called out softly.

 

The mound of blankets shifted. A hand emerged, grasping the edge of the mattress. Inko felt the breath catch in her throat. The hand was massive, easily twice the size it had been a few days ago, but it wasn't just the size that was shocking. The skin was tanned, calloused, and rough, crisscrossed with faint, silvery lines that looked like ancient scars. The fingers were thick, resembling steel cables wrapped in leather, ending in nails that looked more like blunted talons.

 

With a deep, guttural grunt, the figure beneath the blankets sat up, tossing the covers aside.

 

Inko slapped a hand over her mouth to stifle a scream.

 

Her son—her sweet, soft-cheeked, four-year-old Izuku—was gone. In his place sat a giant. Even sitting down, he towered over her. He looked to be the size of a grown man, perhaps even larger, but his proportions were entirely alien to the modern world.

 

His neck was thicker than his head, an absolute trunk of solid, interwoven muscle designed to absorb catastrophic impacts. His shoulders were impossibly broad, sloping down into a chest that looked like a fortress of flesh. Every inch of him was covered in hyper-dense, rippling musculature that looked as hard as granite.

 

But it was his face that made Inko’s heart ache. The mop of unruly green hair remained, though it was thicker, wilder, and cascaded down his thick neck like a lion’s mane. His emerald green eyes were the same color, but the shape had changed—they were wider, sharper, and held a predatory depth that stripped away centuries of human civilization. When he opened his mouth to yawn, letting out a sound that was half-yawn, half-roar, Inko saw rows of brilliantly white teeth. His canines were elongated, sharp, and slightly curved.

 

He was a monster. A beast born in a modern hospital room.

 

Izuku blinked heavily, looking around the room as if seeing it for the first time. His nose twitched. He sniffed the air, once, twice, his nostrils flaring wide. His gaze locked onto Inko.

 

Inko froze. Every instinct buried deep in her human DNA screamed at her to run. The primal part of her brain, the part that remembered the dark nights of the Pleistocene epoch when humanity huddled in caves fearing the monsters in the dark, told her that she was looking at an apex predator.

 

Izuku leaned forward, the wooden bedframe cracking under his shifting weight. He crawled off the bed, not standing on two legs, but dropping to all fours. He moved with a terrifying, fluid grace, his massive knuckles resting gently on the carpet. He closed the distance between them in an instant, his giant shadow falling over her small, trembling frame.

 

He brought his face inches from hers. He inhaled deeply, taking in her scent.

 

Inko closed her eyes, tears leaking from the corners. He doesn't know me. The fever burned his mind away. He's... he's gone.

 

Then, a massive, heavy, rough hand gently touched her cheek. It was surprisingly warm.

 

Inko opened her eyes. Izuku’s terrifying, wide-eyed stare softened. The sharp, slit-like intensity faded, replaced by the big, innocent green eyes of her little boy. The corners of his mouth curled upward into a wide, toothy grin that showed off those terrifying fangs.

 

He didn't speak. The complex vocal cords required for modern Japanese seemed to be foreign to him now. Instead, he let out a low, vibrating purr that rumbled in his massive chest, and gently nuzzled his forehead against her shoulder, rubbing his cheek against hers just like he did when he was a toddler seeking comfort.

 

The fear vanished, washed away by a torrential flood of maternal love. It didn't matter how big he was. It didn't matter that he looked like he could tear a car in half with his bare hands. He was her son. He was her Izuku.

 

Inko threw her arms around his massive, tree-trunk neck, burying her face in his wild green hair, sobbing uncontrollably.

 

Izuku didn't understand why the matriarch was leaking water from her eyes, but he felt her distress. He wrapped his massive arms around her, careful to tuck his claws away, holding her with a gentleness that defied his monstrous appearance. He let out another deep, soothing rumble, declaring to the universe that as long as he drew breath, nothing would ever harm the matriarch of his pack.

 

 

 

 

"Fascinating... Utterly, completely, and terrifyingly fascinating."

 

Dr. Kyudai Garaki sat in his darkened office, the glow of the X-ray light-box illuminating his bald head and thick mustache. He adjusted his round glasses, his eyes wide with a mixture of professional awe and deep, underlying confusion.

 

Sitting on the examination table behind him was Izuku. Or, rather, crouching on it. The boy refused to sit in the chair. He remained perched on the reinforced steel table in a deep, primal squat, his weight balanced perfectly on the balls of his bare feet, his knuckles resting on the metal. He was currently busy sniffing a tongue depressor before casually biting the end off and chewing the splintered wood as if it were a toothpick.

 

Inko sat in the corner chair, her hands wringing her purse. She looked exhausted, having spent the better part of the morning trying to find clothes that fit her now massive son. He was wearing an extra-large adult tracksuit, and even that was stretching at the seams around his shoulders and thighs.

 

"Doctor... please," Inko said, her voice shaking. "What is wrong with my boy? Is it a gigantification quirk? A mutation?"

 

Dr. Garaki turned in his chair, rubbing his chin. "Mrs. Midoriya, I have been studying Quirks for decades. I have seen bodies modified by genetics to possess engines in their calves, wings on their backs, and skin made of stone. But this... this is not a Quirk."

 

Inko blinked. "Not a Quirk? But... look at him!"

 

"I am looking at him," Garaki said, pointing to the X-ray films pinned to the board. "And I am telling you, biologically speaking, the concept of a 'Quirk' implies an addition to the human genome. A plus-alpha. A mutation on top of the standard homo-sapien blueprint."

 

Garaki walked over to the X-rays, tapping the thick white shapes on the film.

 

"Look at this skeletal structure. Look at the cervical vertebrae. A normal human neck, even one enhanced by a strength quirk, has a specific bone density and joint arrangement. Izuku’s neck bones are interlocked in a way that suggests they are designed to withstand the impact of a high-speed collision with a freight train. They are reinforced with layers of cartilage and secondary anchor points for muscle tendons that do not exist in modern human anatomy."

 

Garaki moved his finger down to the ribs and pelvis.

 

"His bone marrow is so dense it practically blocked out the X-ray machine. His muscle fibers... well, they aren't human. The composition, the sheer amount of fast-twitch and slow-twitch muscle tissue packed into his frame... it defies physics. It is a biological miracle that his heart can pump blood through a body this dense, but his heart is twice the size of a normal human's, and his lungs are massive."

 

"I don't understand," Inko whispered.

 

"Mrs. Midoriya," Garaki said, his voice dropping to a whisper of genuine reverence. "Your son isn't a mutant. He hasn't evolved forward. He has evolved backward. Way, way backward. His physiology resembles something out of the Cretaceous period. He is built like an apex predator from an era before the ice ages, a creature designed to wrestle dinosaurs and hunt mammoths with its bare hands. He isn't a human with a quirk. He is... a prehistoric throwback. A genetic anomaly."

 

On the table, Izuku spit out the chewed wood of the tongue depressor. He tilted his head, his sharp green eyes locking onto a fly buzzing near the fluorescent light above.

 

Without warning, Izuku’s massive leg muscles contracted. He didn't jump; he exploded upward. The steel examination table dented inward beneath his feet, and he cleared the eight feet of space to the ceiling in a fraction of a millisecond. His jaws snapped shut with a resounding CRACK that echoed like a gunshot in the small room.

 

He landed perfectly on all fours, making absolutely no sound as his feet and hands hit the linoleum floor. He chewed thoughtfully for a second, swallowed the fly, and then looked back at Inko, offering her a wide, bloody-looking grin, clearly proud of his 'hunt'.

 

Inko buried her face in her hands.

 

Garaki was speechless. He looked at the massive dent in his solid steel examination table, then at the boy who had just defied gravity and reaction time to catch a fly in his teeth.

 

"For official registry purposes," Garaki managed to say, clearing his throat, "we will classify it as a Mutation-class Quirk named 'Prehistoric Physiology'. It will save you a lot of questions from the government. But Mrs. Midoriya... I must warn you."

 

Inko looked up.

 

"His mind is linked to that body," Garaki warned, his tone serious. "The instincts that come with a body designed to hunt and survive in a prehistoric jungle will be overwhelming. He may not process the world like we do. Concepts like math, literature, or social etiquette might be entirely lost on him. He will perceive the world in terms of strength, hierarchy, and survival. You must be very careful."

 

Inko looked down at her son. Izuku had crawled over to her chair and was currently resting his massive chin on her knee, looking up at her with those big, soulful green eyes. He let out a soft whine, sensing her stress, and nuzzled her hand.

 

Inko’s fear hardened into steel. She placed her hand on his thick, unruly hair and stroked it.

 

"He is my son," Inko said, her voice devoid of its previous tremble. "I don't care if he's a dinosaur, a caveman, or a monster. I am his mother. I will teach him. I will feed him. And I will love him."

 

Garaki adjusted his glasses, a rare, genuine smile crossing his face. "Then I wish you the best of luck, Mrs. Midoriya. Because feeding him is going to be quite the endeavor."

 

 

 

 

Garaki's warning about feeding Izuku proved to be the understatement of the century.

 

When they returned to the apartment, Inko immediately went to the kitchen. Izuku’s stomach let out a rumble that sounded like distant thunder, shaking the framed pictures on the hallway walls.

 

"Okay, baby, okay. Mommy is making lunch," Inko said, pulling out the ingredients for his favorite meal: Katsudon.

 

Izuku sat on the living room floor, taking up most of the space. He watched her intently, his tailbone wagging slightly—a phantom limb reflex from a body that felt it should have a tail to balance its massive frame.

 

Inko fried the pork, simmered the eggs and onions in the sweet and savory broth, and placed a massive bowl of rice on the table. She poured the katsudon over the rice, the steam rising with a mouth-watering aroma.

 

"Here you go, Izuku! Eat up."

 

Izuku crawled over to the low kotatsu table. He didn't use chopsticks. He leaned down, sniffing the bowl. His nose scrunched up in disgust. He let out a low hiss, backing away from the bowl as if it offended him.

 

"Izuku? What's wrong? It's your favorite."

 

Izuku shook his massive head, his green mane flying. He pointed a thick, clawed finger at the bowl, then crossed his arms in an 'X', shaking his head vehemently. He didn't want it. The smell of the processed oils, the cooked-to-death meat, the refined sugars in the sauce—to his newly awakened olfactory senses, it smelled like ash and chemicals.

 

His stomach roared again. He looked at Inko, his eyes wide, pleading. Hungry.

 

Inko panicked. She opened the fridge, pulling out vegetables. Izuku snorted, turning his head away. She pulled out bread. He ignored it.

 

Finally, she opened the freezer. At the bottom, wrapped in butcher paper, was a massive, three-pound chuck roast she had bought on sale, intending to use it for a stew later in the month.

 

The moment she pulled the frozen block of meat from the drawer, Izuku’s demeanor changed. His pupils dilated, consuming the green irises. He dropped onto all fours, his muscles tensing, a low, rumbling growl vibrating in his chest. His eyes were locked onto the butcher paper.

 

Inko swallowed hard. "This? You want this?"

 

Izuku nodded, a drop of drool slipping past his elongated canines and hitting the floor.

 

"Okay... let me just defrost it and cook—"

 

Before she could finish the sentence, Izuku moved. He didn't snatch it aggressively, but he was so fast Inko barely registered the movement. One second the meat was in her hands, the next it was in his.

 

He didn't bother unwrapping it. He didn't wait for it to thaw.

 

Izuku sank his teeth into the solid block of frozen meat and paper. The sound of his jaws crushing through the frozen muscle fibers and bone echoed through the kitchen like a woodchipper. He ripped a massive chunk free, throwing his head back to swallow it almost whole, the thick muscles of his neck undulating as the frozen lump traveled down his esophagus.

 

"Izuku! The paper! It's frozen!" Inko cried out, horrified.

 

But Izuku didn't care. He took another bite, tearing through the tough, frozen sinew with absolutely zero resistance. His jaws were generating thousands of pounds of pressure per square inch. To him, the frozen beef was no tougher than a piece of soft taffy.

 

In less than ten seconds, the entire three-pound roast was gone.

 

Izuku licked the bloody frost from his lips, letting out a satisfied, booming belch. The wild, predatory look faded from his eyes, replaced once again by the soft, happy gaze of a well-fed toddler. He crawled over to Inko, wrapping his massive arms around her waist, burying his face in her stomach, and purring loudly.

 

Inko stood frozen, staring at the empty space where the roast had been.

 

She realized then that raising Izuku was not going to be a matter of correcting his behavior. It was going to be a matter of adapting to his nature. He was not a boy who needed cooked meals and table manners. He was an apex predator who required raw fuel to maintain his impossible physique.

 

Over the next few weeks, Inko’s life changed drastically. She picked up extra shifts at her part-time job. She learned the schedules of every butcher in the Musutafu district. She learned to haggle, to buy the cheapest, toughest cuts of meat in bulk—bone-in ribs, whole sides of beef, massive slabs of venison and pork that butchers struggled to sell.

 

She stopped cooking his meals. Instead, she became the Keeper of the Meat.

 

Their dynamic shifted into something beautiful, bizarre, and profoundly primal. Izuku worshipped the ground Inko walked on. In his instinct-driven mind, Inko was the ultimate Matriarch of the pack. She was the one who provided the food. She was the one who offered safety and warmth. To Izuku, her small, fragile human form was irrelevant; her status was absolute.

 

If Inko was stressed, Izuku would pace the apartment on all fours, growling at the windows to ward off invisible threats. If Inko was tired, Izuku would lay beside her, radiating a massive amount of body heat, purring until she fell asleep.

 

He didn't speak. He tried, sometimes, mimicking the sounds she made, but his vocal cords were too thick, his jaw too heavy. He communicated in grunts, roars, whines, and body language. A headbutt meant affection. A bared-teeth hiss meant displeasure. A low rumble meant contentment.

 

Despite his terrifying exterior, his heart remained pure. He was gentle with everything smaller than him—which was practically everything. He would sit in the park for hours, letting birds land on his massive shoulders, watching butterflies with wide-eyed wonder. He had no malice in his heart. He was an animal, yes, but a pure one.

 

However, society was not as understanding as his mother.

 

 

 

 

Katsuki Bakugo felt like a god.

 

At the tender age of four, his Quirk had manifested. "Explosion." He could secrete nitroglycerin-like sweat from his palms and ignite it at will. It was flashy, powerful, and destructive. The teachers praised him. His parents boasted about him. The other children at the playground looked at him with a mixture of awe and fear.

 

He was the strongest. He was the alpha. He was destined to be the Number One Hero, greater even than All Might. The world was his to conquer, and everyone else was just an extra, meant to step aside and watch him rise.

 

Especially that quirkless, whimpering loser, Deku.

 

Katsuki hadn't seen Izuku in weeks. The rumor around the neighborhood was that Izuku had gotten sick, that his quirk was delayed, or that he didn't have one at all. Katsuki didn't care. He was just eager to show off his new power to the green-haired crybaby, to cement his place at the top of the food chain.

 

It was a warm Tuesday afternoon when Inko finally decided it was time for Izuku to get some fresh air. She led him to the local playground.

 

Katsuki was currently standing on top of the jungle gym, his 'throne', with two lackeys standing below him. He was firing off small pops and sparks from his hands, laughing arrogantly.

 

"See that?" Katsuki bragged. "I'm gonna be a hero! Anyone who gets in my way is gonna get blown to bits!"

 

"Wow, Bakugo! You're so cool!" one of the kids cheered.

 

Suddenly, the playground went dead silent.

 

Katsuki stopped his explosions, looking down. The other children were staring toward the entrance of the park, their eyes wide with terror. Some of the younger kids immediately started crying, running to hide behind the slide.

 

Katsuki scowled, looking toward the gate. "What's everyone looking at—"

 

The words died in his throat.

 

Walking through the gate was Auntie Inko. But walking beside her—or rather, lumbering beside her on all fours—was a monster.

 

It was huge. It had to be pushing five feet tall already, despite only being four years old, and it was wider than a refrigerator. It was wearing a custom-made, incredibly baggy pair of shorts and a tank top, revealing skin that looked like tanned leather stretched over boulders. Its neck was a solid column of muscle, and its face was a terrifying mask of wild, unruly green hair and sharp, elongated fangs.

 

"Go play, Izuku," Inko said gently, patting the beast on its massive shoulder. "Be gentle, okay?"

 

The beast let out a low, vibrating grunt that made the sand in the sandbox tremble. It turned its head, and Katsuki saw the eyes.

 

Emerald green.

 

Katsuki’s jaw dropped. Deku?

 

That was Deku? It couldn't be. Deku was small, frail, and cried when you looked at him funny. This thing looked like it ate bears for breakfast.

 

Izuku didn't go to the swings or the slide. He lumbered over to a sunlit patch of grass near the edge of the park. He dropped heavily onto his stomach, crossing his massive arms in front of him, and rested his chin on his wrists. He closed his eyes, his nostrils flaring rhythmically as he basked in the warmth of the sun, entirely unbothered by the terrified stares of the other children.

 

Katsuki felt a hot flash of anger boil in his chest. What the hell is that? That's not a quirk! That's a freak mutation! He thinks he can just show up looking like a monster and steal my spotlight?

 

Katsuki’s pride demanded action. He was the alpha. He had to prove it.

 

"Hey!" Katsuki yelled, sliding down from the jungle gym and stomping over toward the resting giant. His lackeys followed, though they kept a safe distance, trembling violently.

 

Izuku didn't open his eyes. He had smelled Katsuki the moment he entered the park. To Izuku’s hyper-advanced olfactory senses, Katsuki smelled like burnt sugar, ozone, and the sour tang of juvenile aggression. He smelled like a loud, annoying bird. Not a threat. Barely even prey. Just a noisy nuisance.

 

"I'm talking to you, Deku!" Katsuki sneered, stopping a few feet away from Izuku’s massive head. "What the hell is wrong with you? Did you get a quirk that turns you into an ugly gorilla?"

 

Izuku cracked one green eye open. He looked at Katsuki. There was no fear in his gaze. There was no admiration. There was only a profound, ancient apathy. Izuku let out a soft huff of air through his nose, blowing a stray leaf across the grass, and closed his eye again, ignoring the explosive boy.

 

Katsuki’s face turned red. The absolute disrespect. The sheer audacity.

 

"Don't ignore me!" Katsuki roared. He raised his right hand, sweat igniting in his palm. "I've got an amazing Quirk now! I'm better than you! If you don't bow down, I'll blast that ugly face right off your—"

 

BOOM!

 

Katsuki didn't hold back. He slammed his palm forward, unleashing the largest explosion he could muster at four years old. A blast of fire, smoke, and concussive force erupted point-blank against the side of Izuku’s face and shoulder.

 

The sound echoed off the nearby apartment buildings. The other children screamed. Inko, sitting on a bench reading a book, didn't even flinch. She just sighed, turning a page.

 

Smoke billowed across the grass. Katsuki stood panting, a wicked grin spreading across his face. That'll teach him. Freak.

 

But as the smoke cleared, Katsuki’s grin vanished.

 

Izuku hadn't moved. He hadn't been blown back. He hadn't even flinched.

 

The explosion, which would have given a normal child third-degree burns and a concussion, had done absolutely nothing to Izuku’s prehistoric physiology. The skin on his shoulder wasn't burned; it wasn't even red. The intense heat of the explosion had merely singed a few hairs on his arm. His skin, designed to withstand the crushing jaws of a Tyrannosaurus Rex and the freezing colds of the ice age, barely registered the heat as a warm breeze.

 

Izuku slowly opened both eyes. The peaceful, apathetic look was gone.

 

He sat up on his haunches, his massive torso blocking out the sun. He looked down at Katsuki.

 

Katsuki took a step back, his breath hitching.

 

Izuku didn't look angry. Anger was a human emotion. Izuku looked curious, and slightly annoyed. He tilted his head, his thick neck muscles bulging, and leaned forward until his face was inches from Katsuki’s.

 

Katsuki tried to raise his hands, tried to spark another explosion, but his body wouldn't obey. A cold, paralyzing dread washed over him. The smell of Izuku up close—musk, raw earth, and the metallic tang of ancient blood—overwhelmed his senses.

 

Izuku looked into Katsuki’s eyes. And then, Izuku smiled.

 

It was not a friendly smile. It was the smile of a creature that had stood at the top of the food chain for millions of years. It was a wide, terrifying grin that stretched from ear to ear, exposing rows of massive, interlocking fangs that looked capable of snapping a femur in half.

 

Izuku’s eyes dilated until they were completely black. The illusion of a civilized world shattered in Katsuki’s mind. In that single, terrifying second, Katsuki didn't see a playground. He didn't see his friends. He saw a dark, humid, primordial jungle. He felt the earth shaking beneath the footfalls of titans. He felt the terrifying, crushing weight of absolute insignificance.

 

He realized, with every fiber of his being, that if this creature wanted to, it could bite his head off in a single motion, and there was nothing in the world that could stop it.

 

Izuku didn't strike Katsuki. He didn't roar. He simply raised one of his massive, heavy hands, and brought it down on top of Katsuki’s spiky blonde hair.

 

Pat. Pat.

 

Two gentle, condescending pats on the head. A gesture a human might give to an aggressive, yapping chihuahua.

 

Then, Izuku turned his back on Katsuki, dropped back onto his stomach, and closed his eyes to resume his nap.

 

Katsuki stood frozen. His legs turned to jelly. His heart hammered in his chest like a trapped bird. The fear was so intense, so deeply ingrained in his DNA, that it bypassed his conscious thought. Slowly, inevitably, a dark stain spread down the front of Katsuki’s shorts.

 

He didn't say a word. He turned around, tears streaming down his face, and ran as fast as his trembling legs could carry him, leaving the playground behind.

 

Izuku didn't watch him leave. He just shifted his weight, getting comfortable in the grass.

 

The hierarchy had been established. The modern world with its flashy quirks and societal rules meant nothing. Here, on this patch of grass in Musutafu, the ancient laws of nature had resumed their reign.

 

The apex predator was resting. And the world would do well not to wake him.

 

 

 

 

News of the "Midoriya Incident" spread through the neighborhood like wildfire. While most of the children were too young to fully articulate what they had seen, the raw terror they exhibited whenever someone mentioned the "Green Giant" spoke volumes. Mothers whispered in the grocery store aisles, eyeing Inko Midoriya with a mixture of pity and apprehension.

 

Inko ignored them all. She had a singular focus: keeping her son fed and happy.

 

By the time Izuku reached his sixth birthday, his growth had slowed down, but it hadn't stopped. He now stood at an imposing five-foot-eight and weighed nearly three hundred pounds of pure, unadulterated muscle mass. He no longer fit in any standard clothing. Inko had to seek out specialty tailors who catered to heroes with gigantification or mutation quirks, draining what little savings she had.

 

Her husband, Hisashi, had stopped calling.

 

He had taken a job overseas shortly after Izuku’s birth, sending a portion of his paycheck back home every month. When Inko had sent him the pictures of four-year-old Izuku following the fever, Hisashi had assumed it was a prank. When she sent a video of Izuku devouring a raw, bone-in leg of lamb with his bare hands, Hisashi’s calls became less frequent. Eventually, the money transfers continued, but the communication ceased entirely. Hisashi Midoriya could not face the fact that his son was not human.

 

Inko cried over it, once.

 

Izuku had found her sobbing in the kitchen late at night. He had lumbered in quietly, his heavy footfalls masked by his terrifying grace. He had sat beside her on the linoleum floor, wrapping his massive arms around her, and let out a deep, mournful wail—a sound that echoed with the sorrow of a creature mourning the loss of a pack member. He didn't understand the concept of a father, or divorce, or abandonment. He only understood that his Matriarch was sad, and that made him sad.

 

From that night on, Inko swore she would never cry over Hisashi again. Izuku was all the family she needed.

 

Izuku’s daily life was a bizarre juxtaposition of modern domesticity and prehistoric survival. He did not attend a normal elementary school. Dr. Garaki had pulled a few strings with the local government, classifying Izuku’s mutation as a "severe developmental divergence," granting him permission to be homeschooled. The reality was that sending Izuku to a classroom full of fragile children was an accident waiting to happen.

 

Izuku’s intelligence was a complex matter. He wasn't stupid. In fact, his situational awareness, problem-solving skills in physical scenarios, and emotional intelligence were staggering. He could track a stray cat through the city based purely on a faint scent trail. He could tell when it was going to rain hours before the clouds rolled in, simply by tasting the air pressure changes on his tongue. He could read the body language of a person from across the street, instantly knowing if they were a threat or harmless.

 

But abstract concepts? Mathematics? Reading? It was like trying to teach a lion to play the piano.

 

Inko tried. She bought colorful picture books and sat with him for hours. Izuku would look at the pages, point a massive finger at a picture of an apple, and grunt.

 

"A. Apple," Inko would say encouragingly.

 

Izuku would sniff the page, realize the apple was made of ink and paper, and lose interest immediately, tossing the book over his shoulder and demanding a back scratch.

 

He only understood the world in physical, tangible terms. Good things were warm, smelled like meat, and sounded like Inko's soft voice. Bad things were loud, smelled like chemicals, and moved erratically.

 

His strength, however, was something Inko had to train him to control constantly.

 

When he was seven, they were walking home from the butcher shop. Izuku was carrying an entire side of beef over his shoulder like it weighed nothing, wrapped in brown paper. A teenage boy on a bicycle, not paying attention to where he was going, turned a corner too fast and crashed directly into Izuku’s legs.

 

The teenager flew off the bike, crying out in pain as he scraped his elbows on the pavement. The bicycle, a sturdy steel-framed mountain bike, hit Izuku’s shin and immediately crumpled. The front tire folded into a taco shape, the frame bending entirely out of alignment.

 

Izuku hadn't even stumbled. He looked down at the ruined bike, then at the crying teenager.

 

His instincts flared. A smaller, weaker creature was making noises of distress. Izuku dropped the side of beef, rushing over to the teenager. He dropped to all fours, his massive face looming over the boy. The teenager, taking one look at the towering, fanged giant sniffing him, screamed in sheer terror, scrambling backward like a crab.

 

Izuku looked confused. He turned to Inko, letting out a soft, questioning whine. Why is it running? It's hurt. I was going to lick its wounds.

 

"It's okay, Izuku," Inko sighed, helping the terrified teenager up and offering to pay for the bike, though the boy was too busy running for his life to accept. "You're just... very intimidating, sweetie."

 

To burn off his excess energy, Inko started taking him to a deserted beach on the outskirts of the city. Dagobah Municipal Beach Park was a dumping ground, filled with illegal trash, broken appliances, and rusted cars. To society, it was a blight. To Izuku, it was a playground perfectly suited to his strength.

 

Here, he didn't have to be careful. Here, he could be the beast he was born to be.

 

Inko would sit on the seawall, knitting a massive sweater that would probably take her a year to finish, while Izuku exercised.

 

His 'workouts' were terrifying to behold.

 

He didn't lift weights. He fought the environment. He would find a rusted-out pickup truck buried in the sand. He wouldn't lift it; he would tackle it. He would hit the truck with his shoulder, his incredible leg muscles driving into the sand, pushing the two-ton vehicle backward as if it were a cardboard box. He would wrestle with refrigerators, wrapping his massive arms around them and crushing the metal until the compressors popped.

 

He ran on all fours along the shoreline, moving with a speed that defied his massive bulk. When he sprinted, his spine aligned perfectly with the ground, his arms and legs pumping in perfect synchronization. He moved like a predatory cat, tearing deep trenches into the wet sand with every stride, easily pushing past sixty miles an hour in short bursts.

 

One afternoon, when Izuku was eight years old, a sudden summer storm rolled in while they were at the beach. The sky turned an angry, bruised purple, and the wind began to howl, whipping the sea into a frenzy.

 

"Izuku! Time to go!" Inko called out, shielding her eyes from the blowing sand.

 

Izuku was standing waist-deep in the churning ocean. He loved the water. It was strong, chaotic, and pushed back against his immense strength. He turned to face his mother, intending to wade out, when the water suddenly receded dramatically, pulling him out further.

 

A rogue wave, easily fifteen feet high, had formed off the coast and was crashing toward the beach.

 

Inko screamed. "Izuku!"

 

Most people, even those with powerful Quirks, would have braced themselves, tried to dive under, or panicked.

 

Izuku Midoriya did none of those things. He looked at the massive wall of water rushing toward him. He didn't see danger. He saw a challenger.

 

Izuku grinned, his fangs bared against the wind. He widened his stance, burying his bare feet deep into the shifting sand beneath the water. He pulled his right arm back, his fist clenching. The muscles in his back coiled like massive steel springs, his lats flaring out so wide he looked like a cobra preparing to strike.

 

The wave crashed over him. Thousands of tons of water, moving with bone-crushing force, slammed into his body.

 

Izuku threw a punch.

 

He didn't have an impact-absorption quirk. He didn't have an air-cannon quirk. He possessed purely kinetic, mechanical force generated by an anatomy designed to rip the heads off prehistoric beasts.

 

His fist moved so fast it created a localized vacuum bubble under the water. The kinetic energy transferred from his fist into the crashing wave.

 

BOOM!

 

A shockwave ripped through the water. A massive geyser erupted upward, blasting a hole twenty feet wide directly through the center of the rogue wave. The remaining water crashed harmlessly around him, unable to move the immovable object that was his body.

 

Izuku stood amidst the foaming surf, the water rushing past his waist. He threw his head back and let out a deafening, triumphant roar that cut through the thunder. He had fought the ocean, and he had won.

 

He waded back to the shore, shaking the water from his massive green mane like a wet dog, sending droplets flying everywhere. He trotted up to Inko, grinning proudly, offering her a wet, sandy hug.

 

Inko, drenched and trembling, couldn't help but laugh. She hugged his massive, solid waist.

 

"You're a very strong boy, Izuku," she whispered. "My strong, wild boy."

 

 

 

 

As the years passed, Inko tried to introduce Izuku to the concept of Heroes. She felt that if he was going to live in this world, he needed a constructive outlet for his immense power. If he saw himself as a protector of the 'pack', maybe he could learn to protect society.

 

She bought him a television and an old VCR for his room—a room that was now devoid of a bed, as Izuku preferred to sleep on a massive pile of thick, heavy blankets on the floor.

 

She put in a tape of All Might’s debut.

 

Izuku sat cross-legged on his blankets, his chin resting in his massive hands, watching the glowing box with mild curiosity. He didn't understand the flashing lights or the dramatic music.

 

Then, the camera panned to a burning building. A massive, muscular man with bright blond hair leapt from the flames, carrying several people on his back. The man threw his head back and laughed, a booming sound of absolute confidence.

 

"Fear not! Why? Because I am here!"

 

Izuku leaned closer to the screen. His nose twitched. He couldn't smell the man through the glass, but he didn't need to. He recognized the body language. He recognized the posture. The broad shoulders, the puffed-out chest, the loud, booming vocalizations to draw attention and assert dominance over the environment.

 

Izuku’s eyes widened. He sat up straight.

 

He didn't see a "Hero" saving "Civilians."

 

Izuku saw the Ultimate Alpha Male defending his territory. He saw a creature that was arguably the strongest beast in this bizarre concrete jungle.

 

When All Might threw a punch on screen, obliterating falling debris with sheer air pressure, Izuku’s heart raced. A primal thrill rushed through his veins. His muscles twitched in sympathy. He wanted to fight that man. He wanted to test his fangs against that man's fists. He wanted to establish the hierarchy.

 

But as he watched All Might gently set the civilians down, patting a crying child on the head to soothe them, Izuku’s perspective shifted slightly. The Alpha was strong, yes, but the Alpha also protected the weak. The Alpha fought the bad things (villains) to keep the pack (society) safe.

 

Izuku let out a low, approving rumble. He understood this. This made sense to his prehistoric brain.

 

Strong beasts protect the pack. Bad beasts attack the pack. Smash the bad beasts. Keep the pack safe.

 

He pointed a massive, clawed finger at the screen, looking back at Inko who was standing in the doorway. He gave her a firm, serious nod.

 

"Do you like him, Izuku?" Inko asked, smiling.

 

Izuku nodded again. He thumped his chest with a closed fist, a gesture he had developed to signify 'good' or 'strong'.

 

He had found his role model. Not a symbol of peace, but a fellow apex predator whose strength he respected.

 

From that day on, Izuku’s demeanor changed slightly. He became more observant when they went out. He watched the local heroes patrolling the streets. Most of them he found disappointing—weak, relying on flashy tricks rather than raw power, fleeing from danger or struggling with minor threats. They were not Alphas. They were scavengers pretending to be lions.

 

But his desire to protect his territory grew.

 

By the time Izuku turned fourteen, he was a mythical figure in Musutafu. He was the "Giant of Aldera Junior High."

 

He officially attended the school, mostly to fulfill legal requirements. The school board had no idea what to do with him. He didn't fit at a desk. He couldn't hold a standard pencil without snapping it in half, and his attempts to read a textbook usually ended with him getting frustrated and ripping the book in half.

 

The principal eventually reached an agreement with Inko. Izuku would 'attend' school by sitting in the back corner of the gymnasium during the day. He didn't have to take tests. He didn't have to participate in class. As long as he didn't hurt anyone and stayed on the premises, the school would pass him to avoid a discrimination lawsuit.

 

It was a lonely existence, but Izuku didn't mind. He didn't crave the companionship of the other students. He viewed them as fragile, noisy cubs.

 

Bakugo Katsuki also attended Aldera Junior High.

 

For ten years, Katsuki had avoided Izuku like the plague. The sheer, pants-wetting terror of their encounter at the playground was burned into Katsuki’s subconscious. Every time Katsuki felt confident, every time he blew up a desk or bullied a weaker classmate, he would catch a glimpse of Izuku’s massive, towering form lumbering down the hallway, and his bravado would instantly evaporate.

 

Katsuki told himself he wasn't scared. He told himself he was just biding his time, waiting until his explosion quirk was strong enough to blast the freak to the moon. But deep down, in the primitive lizard part of his brain, Katsuki knew the truth.

 

You do not provoke the beast.

 

Izuku, for his part, barely remembered Katsuki. To Izuku, Katsuki was just the loud bird from the playground that smelled like burnt sugar. As long as the loud bird didn't attack his Matriarch, Izuku didn't care what he did.

 

But the world was about to change. The age of heroes and villains was escalating. The concrete jungle was becoming more dangerous, filling with monsters born of human malice.

 

And they were entirely unprepared for a monster born of prehistoric evolution.

 

As Izuku walked home one afternoon, carrying a fresh side of beef over his shoulder, he sniffed the air. The wind was carrying a strange scent. It smelled like raw sewage, stagnant water, and the sharp, metallic tang of human terror.

 

Someone from the 'pack' was in danger.

 

Izuku stopped walking. His posture shifted from a slouching, lazy lumber to a rigid, hyper-alert stance. His emerald eyes dilated, becoming black pools of primal instinct. His lips curled back, exposing a terrifying, fanged grin.

 

The apex predator dropped the beef on the sidewalk. He dropped onto all fours, his massive fingers digging into the concrete.

 

It was time to hunt.

 

The modern city of Musutafu was a sensory overload for a creature born of the Cretaceous period.

 

For fourteen-year-old Izuku Midoriya, the world was a cacophony of overwhelming stimuli. Modern humans walked through their concrete canyons blind and deaf, their weakened senses ignoring the subtle truths of the world around them. But Izuku perceived everything. He could hear the hum of electricity coursing through the power lines above. He could feel the microscopic vibrations in the asphalt created by subway trains miles beneath his bare feet.

 

But above all else, he could smell.

 

To Izuku, every person had a unique scent profile, a chemical signature that told him what they had eaten, how healthy they were, and, most importantly, what they were feeling. Fear smelled like sour milk and rusted iron. Joy smelled like warm honey. Aggression smelled like ozone and burning sulfur.

 

Today, the city smelled relatively peaceful, a blend of exhaust fumes, blooming cherry blossoms, and the overpowering, mouth-watering aroma of the prize slung over his massive right shoulder.

 

It was Tuesday, which meant it was wholesale delivery day at the Tanaka Meat Market. Mr. Tanaka, a balding man with a meat-cleaver Quirk that made his hands incredibly sharp, always set aside the "scraps" for the Midoriyas. Today’s prize was an entire hindquarter of a cow, bone-in, weighing roughly one hundred and fifty pounds. It was wrapped in layers of thick butcher paper, but to Izuku, the paper might as well not have existed. He could smell the rich, raw marrow, the dense muscle fibers, the tantalizing iron of the blood. His stomach let out a low, rumbling growl that sounded like a rockslide.

 

He walked with his signature lumbering gait, his immense frame taking up half the sidewalk. Despite standing a towering six-foot-seven and weighing close to four hundred pounds of hyper-dense prehistoric muscle, he moved with a terrifyingly silent grace. He walked on the balls of his bare feet, his heels rarely touching the ground, his knees slightly bent to absorb his own massive weight. He wore custom-made, incredibly baggy sweatpants and a massive, stretched-out tank top that did nothing to hide the thick, corded muscles of his arms and chest.

 

Pedestrians parted before him like the Red Sea. They didn't just step aside; they pressed themselves against buildings, holding their breath as the giant passed. Izuku didn't pay them any mind. They weren't threats. They weren't prey. They were just part of the background noise.

 

His mind was focused entirely on getting back to the apartment, dropping the meat at the Matriarch’s feet, and gorging himself until he fell asleep on his pile of blankets.

 

He decided to take a shortcut under a low bridge. It was darker here, the shadows cooling the afternoon air. The sound of traffic above was muffled.

 

Izuku stopped.

 

His nostrils flared. The scent of the raw beef was suddenly overpowered by something else. It was a vile, nauseating stench. It smelled like stagnant sewer water, rotting garbage, and the distinct, oily slick of malice. It smelled like a predator. But not a clean, noble predator like a tiger or a wolf. It smelled like a parasite.

 

From the manhole cover a few yards ahead, a dark, viscous liquid began to bubble and seep outward. It didn't flow like water; it piled onto itself, defying gravity, rising into a towering, gelatinous mound of dark green sludge. Two massive, bulbous eyes formed in the center of the mass, followed by a jagged maw of liquid teeth.

 

"Well, well, well," the Sludge Villain gurgled, his voice a wet, echoing rasp. "A massive meat-suit. You're a big one, aren't you? Perfect. I need a place to hide. That blonde maniac is right on my tail. Your body will make a perfect camouflage!"

 

Izuku didn't drop the beef. He didn't take a fighting stance. He just stood there, his head tilted slightly to the side, his emerald eyes staring blankly at the undulating mass of liquid. He didn't understand the words the creature was saying, but he understood the intent. The creature was trying to assert dominance. It was claiming him as prey.

 

Izuku let out a soft huff of air through his nose. Annoying.

 

With a wet, slurping roar, the Sludge Villain lunged. He shot forward like a tidal wave of sewage, intending to wrap himself around the giant boy, force his way down the windpipe, and take control of the nervous system from the inside out. It was a foolproof strategy that had worked on dozens of victims before.

 

The sludge slammed into Izuku, wrapping around his legs, his torso, and surging up toward his face.

 

"Don't fight it, kid!" the villain laughed, his fluid body constricting. "It'll only hurt for about forty-five seconds! Just open wide!"

 

A thick tendril of foul-tasting sludge forced its way toward Izuku’s mouth, intending to pry his jaws open.

 

This was the villain's first, and gravest, mistake.

 

Izuku’s jaw muscles were not human. His masseter muscles—the muscles responsible for chewing—were anchored to a skull with a sagittal crest, a bone ridge that allowed for a bite force capable of crushing a Triceratops femur.

 

As the sludge pushed against his lips, Izuku simply clamped his mouth shut.

 

The villain pushed harder, trying to leverage his fluid dynamics to slip between the teeth. What the hell? the villain thought. His jaw... it's like solid titanium. I can't even force a drop inside!

 

Izuku frowned. He didn't like being covered in this cold, foul-smelling liquid. It was ruining the scent of his beef.

 

Deciding he had had enough of this strange, wet creature, Izuku opened his mouth.

 

"Ah! Finally gave up!" the villain cheered, surging forward to pour himself down the boy's throat.

 

Instead of inhaling, Izuku bit down.

 

He didn't just close his teeth; he snapped his jaws shut with the concussive force of a hydraulic press. The sheer kinetic energy of his teeth colliding created a localized shockwave, a deafening CRACK that echoed under the bridge.

 

The Sludge Villain shrieked. It wasn't a physical severing of a limb—he was made of fluid, after all—but the sudden, catastrophic pressure change within his liquid body disrupted his molecular cohesion. It felt like being hit by a localized bomb.

 

Izuku had a mouthful of the villain. He swished it around his mouth for a fraction of a second, his tastebuds analyzing the organic composition.

 

His face scrunched up in an expression of pure, unadulterated disgust. It tasted exactly like it smelled. Like bad swamp water, rotten eggs, and battery acid. It was absolutely inedible.

 

With a loud, exaggerated PATOOEY!, Izuku spat the chunk of sludge out. The glob of villain hit the concrete wall with enough force to crack the cement, splattering into a fine, useless mist.

 

Izuku wiped his tongue with the back of his free hand, letting out a low, vibrating growl of displeasure. He shook himself like a wet dog, his massive muscles rippling, instantly dislodging the rest of the sludge that had wrapped around his body. The villain's fluid form splattered against the pavement, completely unable to maintain a grip on the hyper-dense, sweat-slicked skin.

 

"What... what are you?!" the villain gasped, pulling his scattered mass back together, his bulbous eyes wide with genuine shock. He had tried to crush the boy's chest, but it had been like trying to squeeze a solid block of tungsten.

 

Izuku didn't answer. He didn't even look at the villain again. The creature was neither food nor a threat. It was just a bad-tasting puddle.

 

Adjusting the massive side of beef on his shoulder, Izuku stepped over the cowering villain, his heavy footfalls shaking the ground as he continued his walk home, grumbling in his chest about the bad taste in his mouth.

 

The Sludge Villain remained frozen on the ground, trembling. "What the hell was that thing? A mutation? A giant?" He shuddered, pulling himself toward the sewer grate. "Whatever. I need to get out of here before—"

 

"FEAR NOT!"

 

The manhole cover completely blew off its hinges, rocketing into the ceiling of the underpass. From the depths of the sewer, a towering figure erupted, landing with a ground-shattering thud.

 

He was a mountain of muscle, clad in a white t-shirt and cargo pants, his blonde hair styled into two distinct, gravity-defying tufts. The sheer aura radiating from him was palpable, a suffocating pressure of absolute, unwavering justice.

 

It was All Might, the Symbol of Peace.

 

"FOR I AM HERE!" All Might boomed, his trademark smile plastered across his face. He raised a massive fist, preparing to unleash a shockwave to scatter the villain.

 

But he stopped. He blinked, looking down.

 

The Sludge Villain was already scattered, shivering in a puddle, looking utterly traumatized. Beside the puddle, on the concrete wall, was a massive, crater-like indentation.

 

All Might leaned in closer, his smile faltering slightly in confusion. Inside the cracked concrete crater, perfectly preserved in the shattered cement, were the distinct indentations of teeth. Massive, jagged, inhuman teeth.

 

Someone—or something—had literally bitten a chunk out of the villain and spat it with enough force to shatter reinforced concrete.

 

All Might wiped a bead of sweat from his brow. What in the world... Did another hero beat me to it? Who has a Quirk like this? Mount Lady? No, her teeth are normal. Gang Orca? No, the bite radius is entirely different.

 

As All Might stood there puzzling over the bite mark, his pocket vibrated. He pulled out a specialized comms device. His time limit was running perilously low. A sharp pain lanced through his left side, a grim reminder of his hidden, devastating injury. He coughed, a few drops of blood speckling his hand.

 

"Damn it... I don't have time to investigate," All Might muttered, his booming voice dropping to a strained whisper. He quickly pulled two empty two-liter soda bottles from his grocery bag and began scooping the shivering, compliant Sludge Villain into them.

 

He needed to get this villain to the police station before he reverted to his withered form. But as he leapt into the sky, soaring over the city of Musutafu, his mind kept wandering back to that bite mark. The sheer, raw power required to do that... it wasn't just a strong Quirk. It was a terrifying display of physical supremacy.

 

He just hoped whoever had done it was on the side of the angels.

 

 

 

 

Katsuki Bakugo walked through the Tatooin Shopping District with his hands shoved deep into his pockets. He was flanked by two of his classmates, who were currently animatedly discussing their plans for high school.

 

"You're going to U.A., right, Bakugo?" the kid with the elongated fingers asked. "Obviously! You aced the mock exams, and your Quirk is easily top-tier. You're a shoo-in for the hero course."

 

Katsuki kicked a stray soda can, sending it clattering into an alleyway. "Of course I am. I'm going to be the Number One Hero. I'm going to surpass All Might, get rich, and have everyone looking up to me."

 

"What about the giant?" the other kid asked nervously, immediately lowering his voice as if saying the words out loud would summon the beast. "Midoriya. I heard a rumor he applied to U.A. too."

 

Katsuki’s footsteps hitched for a fraction of a second. His chest tightened, a cold spike of adrenaline piercing his heart. He violently repressed the memory of that day at the playground—the sheer, paralyzing terror of those black, dilated eyes, the feeling of absolute helplessness as the massive hand patted his head.

 

"Shut up about that freak!" Katsuki barked, a small explosion popping in his palm to emphasize his point. The two lackeys flinched backward. "He's not a hero! He's a brain-dead gorilla! U.A. doesn't accept animals. They accept people with actual skills. He's just a giant, dumb target!"

 

Katsuki yelled the words, hoping volume would substitute for truth. But he knew. He knew that his explosions, his pride, his entire worldview—they were all fragile glass constructs that shattered the moment Izuku Midoriya entered the room. He hated Izuku. He hated the giant for making him feel weak. He hated the giant for not even caring enough to fight back.

 

As Katsuki fumed, entirely absorbed in his own aggressive insecurities, he didn't notice the wet, slapping sound emerging from the alleyway behind him.

 

All Might, in his haste, had dropped one of the soda bottles. The fall hadn't killed the villain, but it had shattered the plastic, freeing the Sludge Villain into the alley. Traumatized from his encounter with the giant, and desperate for a host before All Might returned, the villain was operating on pure, desperate instinct.

 

And right in front of him was a teenage boy radiating aggression and power.

 

"A meat-suit with a strong Quirk," the Sludge Villain gurgled, lunging from the shadows. "Perfect!"

 

Katsuki didn't even have time to turn around. The gelatinous mass slammed into his back, engulfing him in a matter of seconds. The foul-smelling liquid forced its way into Katsuki’s nose and mouth, cutting off his air supply.

 

Panic, raw and unfiltered, seized Katsuki’s mind. He couldn't breathe. He was drowning on dry land.

 

No! I'm the strongest! I'm not going to die like this!

 

Katsuki’s survival instincts kicked in. He raised his hands, nitroglycerin sweat pouring from his palms, and ignited it.

 

BOOM! BOOM! BOOM!

 

Massive explosions ripped through the shopping district. Storefront windows shattered, awnings caught fire, and bystanders screamed, fleeing in terror. But the explosions didn't help. The villain's fluid body simply absorbed the blasts, reforming instantly around the boy. In fact, Katsuki’s quirk was actively making the situation worse, turning the narrow street into a blazing inferno.

 

Within minutes, the pro heroes arrived. Death Arms, a hero with incredible physical strength; Kamui Woods, an arboreal hero capable of manipulating his wooden body; and Mt. Lady, a giantess capable of growing to enormous heights.

 

They stood at the perimeter of the fire, completely useless.

 

"I can't grab him!" Death Arms yelled, shielding his face from the intense heat. "He's pure fluid! My punches just go right through him!"

 

"There's too much fire! My wood will ignite if I get close!" Kamui Woods gritted his teeth, focused on pulling civilians away from the blaze.

 

Mt. Lady stood helplessly at the edge of the street. "I need at least a two-lane road to use my Quirk! I can't fit in there!"

 

The heroes were paralyzed. They were waiting for someone with a suitable Quirk to arrive. They were treating the situation like a puzzle that lacked the right piece.

 

In the center of the inferno, Katsuki was losing consciousness. His lungs burned, screaming for oxygen. His explosions were growing weaker. He looked out through the viscous green sludge, his red eyes locking onto the pro heroes. He saw them standing there. He saw them hesitating.

 

Why aren't they helping me? Why are they just watching?!

 

Tears of frustration and fear leaked from his eyes, instantly swallowed by the sludge. This was it. He was going to die here, suffocated in an alleyway.

 

 

 

 

Ten blocks away, Izuku Midoriya was sitting on the floor of his apartment, blissfully tearing his teeth into the raw, bloody hindquarter of the cow. Inko was at the kitchen sink, washing dishes and humming a gentle tune.

 

It was a peaceful afternoon.

 

Then, Izuku’s right ear twitched.

 

Despite the distance, despite the walls of the apartment building, he heard it. A muffled series of concussive pops. Boom. Boom. Boom.

 

Izuku stopped chewing. He swallowed the massive chunk of meat whole, licking the blood from his lips. He recognized that sound. He recognized the specific chemical signature of the explosions. It was the loud, annoying bird. The cub with the sparky hands.

 

Izuku didn't care about the bird. He lowered his head back to the meat.

 

But then, the wind shifted. A breeze blew through the open window of the apartment, carrying a cocktail of scents from the shopping district.

 

Izuku smelled the smoke. He smelled the fire.

 

He smelled the foul, putrid scent of the swamp-creature he had bitten earlier.

 

And beneath all of that, cutting through the smoke and the sludge like a razor blade... he smelled fear. He smelled the distinct, metallic tang of human terror. It wasn't the generalized fear of a crowd. It was the sharp, localized terror of a specific individual. It was the cub. The cub was being attacked by the swamp-creature.

 

Izuku froze.

 

In the complex, primitive hierarchy of Izuku’s mind, the world was divided into simple categories. There was the Matriarch (Inko), who must be protected at all costs. There was the Alpha (All Might), who he respected. There was prey (food). There were rival predators.

 

And then, there was the Pack.

 

The Pack consisted of everyone who lived in his territory. The citizens of Musutafu. The students at his school. The loud, annoying cub. They were weak. They were fragile. But they were his. They belonged to his territory.

 

And an outside predator—a foul-tasting parasite—had entered his territory and was currently trying to devour one of his cubs.

 

To a prehistoric apex predator, this was the ultimate insult. This was a challenge to his dominance.

 

Izuku dropped the meat. He didn't say a word to Inko. He didn't have time.

 

He scrambled to the window, throwing it open. They lived on the fourth floor. Izuku didn't hesitate. He dove out the window headfirst.

 

Inko screamed, dropping a plate. "Izuku?!" She rushed to the window, looking down.

 

Izuku hadn't fallen. He had twisted mid-air, landing on the side of the brick building like a massive, green-haired lizard. His thick fingers and toes dug effortlessly into the brickwork, crushing the mortar to dust. He scrambled down the side of the building in a matter of seconds, hitting the pavement below with a heavy thud.

 

He dropped to all fours, assuming his sprinting stance. His spine aligned parallel to the ground. His powerful leg muscles coiled tight.

 

He pushed off.

 

The concrete sidewalk beneath his feet shattered instantly, leaving two massive craters where he had launched from. The sheer kinetic force of his acceleration created a localized shockwave that blew out the windows of the first-floor apartments.

 

Izuku tore through the streets of Musutafu. He didn't run like a human. He galloped like a terrifying amalgamation of a silverback gorilla and a hunting cheetah. His massive arms pulled him forward while his piston-like legs drove him at speeds exceeding eighty miles per hour.

 

Cars swerved to avoid him. Pedestrians screamed, diving out of the way of the green blur that tore down the center of the road, leaving a trail of shattered asphalt in its wake.

 

Izuku’s eyes were locked dead ahead. His nostrils flared, tracking the scent. The smell of the swamp-creature was growing stronger. The smell of the cub's fear was growing weaker. The cub was dying.

 

MINE. The singular, primal thought echoed in Izuku’s mind. MY PACK. MY TERRITORY.

 

At the Tatooin Shopping District, the situation had grown dire. Katsuki’s explosions had stopped. His eyes were rolling back in his head. The Sludge Villain was cackling triumphantly.

 

"Just a little more! Give it up, kid! It's over!"

 

Death Arms gritted his teeth, preparing to run into the flames regardless of the burns. "I have to try! I can't just watch him die!"

 

"Wait!" Kamui Woods yelled, pointing down the street. "What is that sound?!"

 

A low, rhythmic, thunderous booming was echoing down the avenue. It sounded like a runaway freight train, but it was moving too fast. The ground began to vibrate. The puddles on the street trembled.

 

"Hey, clear the road!" a police officer yelled into his megaphone, looking down the street. "Whatever that is, it's coming in fast!"

 

Suddenly, a massive, green silhouette erupted from the smoke at the end of the block.

 

It was Izuku. He wasn't slowing down.

 

"What the hell is that?!" Death Arms shouted. "A civilian? A villain? Hey! Stop right there! It's too dangerous!"

 

Izuku didn't stop. He didn't even acknowledge the heroes. To him, they were just noisy birds squawking at the edge of a fight they were too weak to finish.

 

Izuku reached the police barricade. Without breaking stride, his leg muscles contracted, and he launched himself into the air. He soared thirty feet high, a massive, muscular titan eclipsed against the smoke-filled sky.

 

Katsuki, barely conscious, forced his heavy eyelids open. Through the shifting liquid prison, he saw it.

 

The Giant. The Beast. His childhood nightmare.

 

Izuku hung suspended in the air for a fraction of a second. His emerald eyes, wide and completely black with dilated, predatory fury, locked onto the Sludge Villain. His lips curled back into a terrifying, fanged snarl. He let out a roar—not a human yell, but a deafening, chest-rattling roar that sounded like a dinosaur challenging a rival.

 

The roar hit the heroes like a physical blow. Their primal fight-or-flight instincts triggered instantly. Kamui Woods froze. Mt. Lady stumbled backward. Even Death Arms felt his knees lock in pure, unadulterated terror.

 

The Sludge Villain looked up. His bulbous eyes widened in absolute horror. He recognized the giant. He remembered the jaw that had nearly crushed him into atoms.

 

"YOU!" the villain shrieked.

 

Izuku came crashing down like a meteor. He landed directly in the center of the inferno, the sheer impact of his four-hundred-pound frame creating a shockwave that violently blew out the surrounding flames, starving the fire of oxygen in a localized burst.

 

He didn't hesitate. He didn't use a Quirk. He didn't rely on flashy elemental powers.

 

Izuku reached out with both of his massive hands and grabbed the Sludge Villain.

 

The heroes watched in stunned disbelief. "He can't grab him!" Death Arms yelled. "He's a fluid!"

 

But Izuku wasn't trying to grab the fluid. He was using physics.

 

Izuku plunged his thick fingers into the gelatinous mass, finding the physical body of Katsuki Bakugo within. He anchored his left hand around Katsuki’s waist, taking care not to crush the boy's fragile ribs.

 

With his right hand, Izuku grabbed a massive handful of the sludge. His muscles bulged, veins popping against his tanned skin like thick purple ropes. He didn't just pull. He accelerated his arm backward with such terrifying speed and raw kinetic force that the fluid dynamics of the villain couldn't adapt in time.

 

Izuku created a physical vacuum with his sheer grip strength.

 

SSSHHRRIIIPPP!

 

The sound was nauseating, like a massive sheet of wet canvas being torn in half.

 

Izuku ripped the Sludge Villain apart. He literally tore the liquid body off of Katsuki, using pure, unimaginable physical strength to overpower the cohesive bonds of the villain's fluid mutation.

 

The villain screamed in agony, his mass violently separated.

 

Izuku yanked Katsuki free. He pulled the gasping, coughing blonde boy against his massive chest, sheltering him.

 

Then, Izuku turned his attention back to the villain. The beast was angry. The parasite had touched his pack.

 

Izuku raised his right leg, bringing his knee up to his chest, and drove his bare foot forward in a devastating front kick.

 

He didn't kick the villain directly. He kicked the air in front of the villain.

 

His leg moved so fast it broke the sound barrier. The resulting sonic boom generated a massive wall of pressurized air. The shockwave hit the remaining mass of the Sludge Villain, splattering him against the brick wall of the alleyway with the force of a hurricane. The villain was reduced to thousands of harmless, quivering droplets, instantly knocked unconscious by the sheer concussive force.

 

Silence fell over the shopping district. The fires had been blown out by the shockwave. The villain was defeated.

 

In the center of the street stood the beast. Izuku lowered his leg. He stood up straight, his massive frame towering over everyone. He looked down at the coughing boy in his arms.

 

Katsuki looked up, hacking up foul-tasting sludge. His red eyes met Izuku’s emerald green.

 

Katsuki expected to see mockery. He expected the giant to gloat, to assert his dominance, to rub it in that he had saved the "strongest" boy in school.

 

But Izuku didn't do any of that. The feral, terrifying rage melted away from his face. His eyes softened, returning to their normal, dopey green shape. He looked at Katsuki, tilting his head slightly, and let out a soft, inquiring whine. He reached up with a massive hand and gently patted Katsuki on the head.

 

Are you okay, little bird?

 

It was exactly the same gesture from ten years ago at the playground. But this time, it wasn't a dismissal of a threat. It was a gesture of protection.

 

Katsuki’s mind short-circuited. His pride, his fear, his worldview—everything collapsed. He didn't yell. He didn't use explosions. He just stared at the giant who had ripped a fluid monster in half with his bare hands, entirely incapable of processing what had just happened.

 

 

 

 

The silence was broken by the sound of coughing.

 

In the crowd of bystanders, a skeletal, sickly-looking man with messy blonde hair pushed his way to the front. Toshinori Yagi—the true, withered form of All Might—clutched his bleeding side, his blue eyes wide with absolute awe.

 

He had followed the explosions. He had berated himself the entire way, hating his useless, broken body for failing to secure the villain, hating himself for standing in the crowd while a boy suffocated. He had been preparing to force a transformation, fully knowing it might literally kill him.

 

But then, the green meteor had arrived.

 

Toshinori had watched the entire spectacle. He had seen the sheer, unadulterated physical power. He had recognized the boy—the massive, hulking teenager was the only creature capable of leaving that bite mark in the concrete.

 

But what struck Toshinori wasn't the strength. Strength could be trained. Quirks could be born.

 

What struck him was the hesitation.

 

Or rather, the complete lack of it.

 

The pro heroes had hesitated. They had analyzed the situation, calculated the risks, and deemed their Quirks unsuitable. They had waited.

 

But this boy hadn't waited. The moment he saw someone in danger, his body had moved on its own. He didn't care about the flames. He didn't care about the fluid mechanics of the villain. He had simply acted, driven by a primal, burning desire to protect.

 

There are stories about every great hero, Toshinori thought, tears pricking the corners of his sunken eyes. How they all have one thing in common. Their bodies moved before they had a chance to think.

 

This beast, this terrifying giant, possessed the purest, most unfiltered heart of a hero Toshinori had ever seen.

 

The police eventually broke the spell, rushing forward to secure the perimeter. The pro heroes shook off their shock and approached Izuku.

 

"Hey, kid!" Death Arms yelled, marching up to Izuku. "What the hell were you thinking? You can't just charge into a villain attack! You don't have a license! You could have been killed, or gotten the hostage killed!"

 

Kamui Woods nodded in agreement. "It was incredibly reckless. We had the situation under control. We were waiting for a hero with a suitable Quirk."

 

Izuku slowly turned his head to look at Death Arms. He gently set Katsuki down on the pavement.

 

Izuku didn't understand the words "license" or "reckless". But he understood the tone. These weak, brightly colored men were barking at him. They had stood by and let the cub almost die, and now they were barking at the one who saved him.

 

Izuku didn't bark back. He didn't need to.

 

He took one step forward, towering over Death Arms. He widened his stance, puffing his massive chest out, and looked down at the hero. He didn't roar. He just let out a low, vibrating growl from deep within his chest. It sounded like an idling chainsaw.

 

Death Arms instantly stopped talking. The color drained from his face. The sheer, overwhelming aura of the apex predator bore down on him. Every instinct in the pro hero's body screamed at him to submit, to look away, to show his throat. He took a slow, terrified step backward.

 

Satisfied that the noisy bird had been silenced, Izuku turned his back on the heroes. He gave Katsuki one last gentle pat on the head, let out a soft snort, and dropped back onto all fours.

 

With a powerful leap, he cleared the crowd of bystanders entirely, landing softly on the roof of a nearby building, and bounded away toward his apartment. His meat was getting warm, and the Matriarch was probably worried.

 

Katsuki sat on the pavement, surrounded by paramedics. He watched the massive green figure disappear over the rooftops.

 

"Hey, kid, you're incredibly brave," a paramedic said, wrapping a blanket around Katsuki’s shoulders. "Holding out against a villain like that. You've got the makings of a great hero."

 

Katsuki didn't respond. He looked down at his trembling hands. The hands that could create explosions. The hands that he thought made him a god.

 

They were nothing. His power was a parlor trick compared to the raw, ancient force of nature that lived down the street.

 

For the first time in his life, Katsuki Bakugo realized he wasn't the alpha. He was just a cub. And he hated it. But beneath the hate, buried deep beneath his pride, a tiny seed of genuine respect for the giant took root.

 

 

 

 

The sun was setting by the time Izuku returned to the apartment. He climbed back through the window, slightly smelling of smoke and ozone.

 

Inko had cleaned up the broken plate and was sitting at the table, her hands wrung tightly in her lap. When Izuku landed inside, she rushed over to him, furiously checking his arms and face for burns.

 

"Izuku! Where did you go?! You smelled something, didn't you? Are you hurt?"

 

Izuku purred, gently nudging his massive head against her shoulder to reassure her. He pointed out the window, then thumped his chest. I protected the territory. Pack is safe.

 

He immediately went to the massive slab of beef on the floor, picked it up, and tore a huge chunk off, chewing happily. Fighting always made him hungry.

 

Before Inko could scold him further, there was a loud, booming knock at the front door.

 

Inko jumped. She cautiously walked to the door, peering through the peephole. She gasped, quickly throwing the deadbolt and opening the door.

 

Standing in the hallway was a shockingly skinny man with sunken eyes and messy blonde hair. He wore a baggy suit that looked several sizes too large.

 

"Um... hello?" Inko asked. "Can I help you?"

 

The sickly man smiled, a surprisingly radiant, heroic smile. "I apologize for the intrusion, Mrs. Midoriya. My name is Toshinori Yagi. Though, your son might recognize me in a different form."

 

Suddenly, the frail man tensed. Steam erupted from his body. In a fraction of a second, his muscles expanded, his spine straightened, and the sickly man was replaced by a towering, grinning mountain of muscle.

 

"I AM HERE!" All Might boomed, though he immediately hunched over, trying not to hit his head on the ceiling of the hallway. "To speak with your boy!"

 

Inko fainted. She simply rolled her eyes back and collapsed.

 

Before she hit the floor, a massive green blur crossed the living room. Izuku caught his mother gently with one hand, laying her softly on the sofa.

 

Then, Izuku turned to face the door.

 

He stared at All Might. All Might stared back.

 

Izuku dropped his meat. He didn't drop to all fours. He stood up to his full, towering height of six-foot-seven. For the first time in his life, he was looking someone directly in the eyes. All Might was actually slightly taller, standing at seven-foot-two, but Izuku’s sheer width and muscle density made them look evenly matched.

 

Izuku sniffed the air. The man smelled like blood, exhaustion, and overwhelming, absolute power.

 

Izuku’s eyes widened. He recognized the posture. He recognized the smell of the ultimate strength. It was the man from the glowing box. It was the Alpha.

 

All Might looked at the boy. Up close, the sheer presence of the prehistoric mutation was terrifying. The boy was built like a mythological titan. But All Might saw the way the boy had caught his mother. He saw the gentleness in those sharp, fanged hands.

 

"Young Midoriya," All Might said, his booming voice softening into something deeply respectful. "I saw what you did today. You threw yourself into danger to save a life, without hesitation, without a Quirk to aid you against that specific villain. You acted on pure instinct."

 

Izuku tilted his head. He didn't understand the words. He let out a low, inquisitive rumble.

 

"I... I see," All Might sweatdropped. "Dr. Garaki's file mentioned your communication barriers. I'll keep it simple."

 

All Might stepped into the apartment, closing the door behind him. He deflated, returning to his skeletal form. He coughed up a bit of blood into a handkerchief.

 

Izuku frowned. The Alpha was shrinking. The Alpha was bleeding. Izuku felt a pang of concern. He walked over to the frail man, sniffing him, and gently prodded All Might’s chest with a thick finger.

 

"I'm alright, my boy," Toshinori chuckled weakly. "This is my true form. I was injured a long time ago. My power... it is fading. I cannot remain the Alpha—the Symbol of Peace—for much longer."

 

Izuku understood that. The Alpha was old. The Alpha was wounded. The pack would be vulnerable without a strong leader.

 

Toshinori looked up, his blue eyes piercing. "I have been searching for a successor. Someone to inherit my power. Someone with the heart of a true hero. I believed I needed someone with a strategic mind, or a flashy Quirk. But today, you showed me that true heroism is an instinct. A primal drive to protect the pack."

 

Toshinori raised his hand. "My Quirk is called One For All. It is a sacred torch, a stockpile of power passed down from generation to generation. It enhances physical strength to unimaginable levels. But it requires a vessel capable of holding it. A normal human body would be blown apart by the sheer recoil of the power."

 

Toshinori looked at Izuku’s hyper-dense, monstrously thick musculature.

 

"But you... your body is a fortress. You are built to withstand forces that would shatter modern man. You don't need ten months of rigorous training to build a vessel. You were born ready."

 

Toshinori reached up and plucked a single strand of golden hair from his head. He held it out to the giant boy.

 

"I offer you my power, Young Midoriya. I ask you to take this torch. To become the next Alpha. To protect this world with your strength. Will you accept it? Will you eat this hair, and inherit One For All?"

 

Izuku looked at the frail man. He looked at the strand of hair.

 

He understood the concept perfectly. In the wild, when an old alpha steps down, he passes his strength, his territory, and his duties to the strongest young male in the pack.

 

The frail man was offering him the position of Alpha. He was offering him the power to protect the Matriarch, to protect the territory, forever.

 

Izuku didn't hesitate. He didn't contemplate the philosophical weight of the decision. He was a creature of action.

 

He leaned forward, opening his massive, fanged jaws, and delicately bit the single strand of hair from Toshinori’s fingers.

 

He chewed once, and swallowed.

 

Toshinori blinked. "Oh. Well, that was fast. Usually, there's a bit of a dramatic pause, or—"

 

Izuku didn't hear him. The moment the hair hit his stomach, his prehistoric, hyper-efficient digestive system dissolved the DNA instantly.

 

A spark ignited within him.

 

It wasn't a sudden explosion of power. It was a deep, resonant awakening. The ancient, stockpiled energy of eight generations of heroes flooded into his bloodstream. It searched for a vessel to inhabit, expecting the fragile, delicate nervous system of a modern human.

 

Instead, the quirk found a biological fortress. It found muscle fibers denser than steel wire. It found bones reinforced with prehistoric cartilage. It found a heart large enough to pump the immense power through the body without tearing the veins apart.

 

One For All settled into Izuku Midoriya’s body not as an alien intruder, but as the final, missing piece of an apex predator.

 

Izuku’s eyes snapped wide open. They glowed with a terrifying, ethereal emerald light. Red, crackling energy—like primitive, wild lightning—erupted from his skin, dancing across his thick muscles.

 

He let out a breath, and the sheer air pressure of his exhalation rattled the windows.

 

Toshinori stepped back, shielding his eyes from the blinding aura. He felt a shiver of pure, unadulterated awe run down his spine.

 

He hadn't just passed his Quirk to a hero. He had armed a dinosaur with a nuclear warhead.

 

Izuku clenched his massive fists, feeling the crackling energy coursing through his veins. He looked at Toshinori, flashing that wide, terrifying, fanged grin, and let out a booming, triumphant roar that shook the very foundations of Musutafu.

 

The Alpha had arrived. And he was hungry for the challenges ahead.

 

The passage of time means little to a creature of instinct. To a beast, there are only the cycles of the sun, the changing of the seasons, and the constant, rhythmic pulse of hunger and satiation.

 

But for Izuku Midoriya, the ten months following his fateful meeting with the Alpha—All Might—were the most agonizing, excruciatingly difficult trial of his entire existence.

 

Not because of physical training. His body was already a masterpiece of prehistoric evolution, a biological fortress that had accepted the sacred torch of One For All without a single torn ligament or shattered bone.

 

No, the agony came from a completely different battlefield.

 

It came from a tiny wooden desk, a fragile graphite stick, and the terrifying, incomprehensible realm of algebra.

 

 

 

 

"Come on, sweetie, you can do this," Inko encouraged, her voice soft but firm. She tapped the open textbook with her finger. "If Train A leaves Musutafu traveling at sixty kilometers per hour, and Train B leaves Hosu at eighty kilometers per hour..."

 

Izuku let out a long, drawn-out whine that sounded like a deflating hot air balloon.

 

He was sitting cross-legged on the floor of the living room, a custom-made, reinforced steel table serving as his desk. He held a pencil between his massive thumb and forefinger. It looked like a toothpick in the hands of a normal man. He was sweating profusely. His hyper-dense muscles, capable of ripping a car in half, were trembling with the effort of simply applying the correct amount of pressure to the paper without snapping the pencil or tearing the notebook to shreds.

 

He stared at the numbers. They danced on the page, mocking him.

 

To Izuku's primal brain, the concept was inherently flawed. Why were the trains moving? Were they hunting? If Train B was faster, Train B was the apex predator of the rails. Therefore, Train B would eat Train A. Math solved.

 

He proudly pointed a massive, calloused finger at Train B and let out a confident grunt, looking to his Matriarch for approval.

 

Inko sighed, rubbing her temples. "No, Izuku. They aren't going to eat each other. We need to find out where they meet."

 

Izuku’s shoulders slumped. He dropped the pencil, which miraculously didn't break, and rested his massive chin on the table. He hated this. He wanted to go to the beach and throw cars. He wanted to run through the forest and wrestle bears. He wanted to practice channeling the crackling green lightning that the Alpha had given him.

 

But the Alpha had explained it clearly, through rudimentary gestures and Inko's translation. To join the hunting grounds of U.A. High School, to become an Alpha in his own right, he had to pass the "Trial of the Mind."

 

"I know it's hard, my big boy," Inko said, reaching over to stroke his wild, thick green mane. Izuku instantly leaned into her touch, a deep, vibrating purr rumbling in his chest. "But you have to pass the written exam. Just enough to let your physical scores carry you. You want to be a hero, right? You want to protect the pack?"

 

At the word pack, Izuku’s ears twitched. His emerald eyes widened, the dopey look fading into absolute, unwavering resolve. He sat up straight, his massive chest puffing out. He picked up the pencil, holding it with the delicacy of a bomb-disposal expert, and looked back at the paper.

 

He would conquer these strange, squiggly symbols. He would defeat the math. He would tear the reading comprehension section limb from limb. For the Matriarch. For the Pack.

 

Over the next ten months, this became his routine. Izuku approached studying not as an intellectual endeavor, but as a battle of attrition. He memorized formulas through sheer, stubborn repetition. He couldn't grasp the abstract logic behind them, so he simply committed the visual patterns to his eidetic, survival-driven memory.

 

When he needed a break, he went to Dagobah Beach. With One For All resting dormant inside him, he would test the limits of his new power.

 

The first time he consciously called upon the quirk, he didn't need to yell "Smash." He simply flexed. Green lightning had erupted from his skin, dancing across his thick veins. The sheer power output was staggering. Where a normal boy might have shattered his arm using one hundred percent, Izuku’s prehistoric joints and hyper-dense cartilage absorbed the recoil. He couldn't access the full one hundred percent—his mind subconsciously bottlenecked the energy to prevent catastrophic overheating—but he could comfortably channel twenty percent of the Alpha's power without breaking a sweat.

 

He didn't clean the beach to train. He cleaned the beach because the piles of trash offended his sense of territory. A good Alpha keeps his den clean. Within three months, the illegal dumping ground was pristine, every refrigerator, crushed car, and rusted microwave hurled over the seawall into a massive recycling barge with terrifying precision.

 

And then, the day of the U.A. Entrance Exam arrived.

 

 

 

 

The morning air was crisp, carrying the scent of blooming cherry blossoms and the sharp, nervous sweat of thousands of teenagers.

 

U.A. High School was an architectural marvel, an imposing fortress of glass, steel, and concrete. To the hundreds of aspiring heroes walking up the main path, it was a symbol of hope and dreams.

 

To Izuku Midoriya, it was the ultimate proving ground. The Colosseum.

 

He walked up the paved path, towering over the sea of students. He wore a custom-tailored dark green tracksuit, as standard uniforms simply could not contain his six-foot-seven, four-hundred-pound frame. His wild hair caught the morning breeze, and his emerald eyes calmly scanned the area, taking in every scent, every sound, every microscopic movement.

 

The crowd parted around him instinctively. Teenagers with gigantification quirks, mutation quirks, and emitter quirks all took one look at the hyper-dense titan and immediately felt a cold shiver of primal dread. They didn't know why, but their bodies told them to keep a ten-foot radius.

 

Izuku ignored them. They were noisy, fragile little birds. He was focused on the massive gates of the school.

 

A few yards ahead of him, Katsuki Bakugo was marching up the path, his hands shoved deep into his pockets, an angry scowl plastered on his face. Katsuki had spent the last ten months training his explosion quirk to its absolute limit, desperate to wash away the humiliating memory of the Sludge Villain incident. He was determined to prove he was the strongest.

 

But as the shadow of the giant fell over him, Katsuki’s steps hitched. He didn't turn around. He didn't yell. He just subtly quickened his pace, his eyes locked straight ahead, his heart hammering in his chest. Don't look at it, Katsuki’s inner voice screamed. Just keep walking.

 

Izuku didn't even notice Katsuki. His attention was suddenly drawn to a change in the air currents, accompanied by a sharp gasp.

 

A girl with round cheeks and short brown hair had tripped over her own feet. The pavement rushed up to meet her face.

 

Before gravity could finish its job, a massive shadow eclipsed her.

 

Izuku didn't think; he just reacted. His arm shot out with a speed that defied his bulk. He didn't grab her arm—he knew his grip strength could accidentally shatter a human radius bone. Instead, he pinched the thick fabric of the back of her uniform jacket between two massive, leathery fingers.

 

Ochako Uraraka squeezed her eyes shut, waiting for the impact. It never came. She was suspended mid-air, dangling inches from the concrete.

 

"Woah!" Ochako gasped, feeling herself being lifted back onto her feet. "Thank you so m—!"

 

She turned around, a bright smile on her face, and immediately froze.

 

Standing before her was a creature out of a mythology book. A neck thicker than a tree trunk. Arms that looked like braided steel cables. And a face that was staring down at her with intense, unblinking green eyes, his sharp, elongated fangs slightly visible as he breathed.

 

Ochako’s soul briefly left her body. Her Quirk was Zero Gravity, but staring at this giant made her feel like she weighed a thousand tons. She couldn't move. She couldn't speak.

 

Izuku leaned in. He gave her a quick sniff. She smelled like strawberries, nervous sweat, and fresh air. Not a threat. A very fragile, clumsy bird.

 

Izuku offered her a wide, toothy grin. To a human, it looked like a tiger baring its fangs before a meal. But Izuku let out a soft, deep rumble in his chest—a gentle purr intended to soothe a frightened cub. He reached out with one massive finger and gently tapped her on the top of her head.

 

Careful, clumsy bird.

 

He then walked past her, his heavy footfalls shaking the pavement slightly, leaving Ochako standing there, trembling like a leaf in a hurricane.

 

"D-Did... did that mountain just save my life?" she whispered to herself, her knees buckling slightly. "And did it... purr?"

 

 

 

 

The written portion of the exam was a blur of sweat, broken pencil leads, and pure, concentrated willpower.

 

Izuku sat in a reinforced chair at the back of the auditorium, entirely ignoring the groans and sighs of the students around him. He treated the test paper like an enemy that needed to be subdued. He recalled the visual patterns of equations Inko had drilled into him. He didn't understand why $x=4$, but he knew the Matriarch wanted him to write down '4', so he wrote down '4'.

 

When the bell rang, signaling the end of the written exam, Izuku let out a massive sigh of relief that rustled the papers of the students sitting three rows ahead of him. The Trial of the Mind was over. Now, it was time for the Trial of the Body.

 

The hundreds of examinees filed into the massive presentation auditorium. Izuku claimed a spot leaning against the back wall, his arms crossed over his massive chest. He was too large to fit in the standard fold-down seats.

 

The lights dimmed, and a spotlight hit the stage.

 

"WHAT'S UP, U.A. CANDIDATES?!" Present Mic screamed, leaning entirely too close to his microphone. "CAN I GET A 'YEAH'?!"

 

Silence echoed through the room.

 

Izuku winced, his thick hands flying up to cover his ears. His prehistoric auditory senses were designed to hear the snapping of a twig from a mile away. Present Mic’s Voice Quirk, amplified by the speakers, felt like physical daggers being driven into his eardrums. He let out a low, irritated hiss, his lips curling back to expose his fangs.

 

"TOUGH CROWD!" Mic continued, unfazed. "LISTEN UP, LISTENERS! I'M HERE TO GIVE YOU THE RUNDOWN ON THE PRACTICAL EXAM!"

 

Mic explained the rules. The faux city. The villain robots. The point system. One point for the light models, two for the mediums, three for the heavies.

 

Izuku tilted his head. Robots. The word didn't translate well in his mind. The screen behind Mic showed pictures of the mechanical constructs.

 

Ah, Izuku thought. Armored beetles. The metallic prey.

 

He understood the concept now. It was a hunting competition. The Alpha of the school wanted to see who could hunt the most metallic beetles. The biggest beetles were worth the most respect. This was a language Izuku spoke fluently.

 

Suddenly, a tall boy with glasses and stiff posture stood up in the middle of the auditorium, a stern expression on his face.

 

"Excuse me! I have a question!" Tenya Iida shouted, his voice ringing out clearly. A spotlight snapped onto him. "On the printout, there are four types of villains listed! If this is a misprint, then U.A., the most prominent hero academy in Japan, should be ashamed of that foolish mistake!"

 

Iida then turned around, pointing a stiff, robotic finger directly at Katsuki Bakugo. "In addition, you over there with the curly hair—"

 

Iida wasn't pointing at Bakugo. He was pointing past Bakugo. He was pointing at the giant leaning against the back wall.

 

"You have been grumbling and shifting your weight this entire time! It is distracting! If you think this is some sort of pleasure trip, then you should leave this place at once!"

 

The auditorium went dead silent. The students sitting near Izuku slowly leaned away, realizing the bespectacled boy had just scolded the beast.

 

Izuku lowered his arms. His emerald eyes narrowed.

 

To Izuku, this stiff, robotic boy was challenging his right to be in the hunting grounds. The noisy bird was squawking at him, demanding he leave the territory.

 

Izuku didn't yell back. He didn't argue logic. He simply uncrossed his arms, pushed himself off the wall, and took a deep breath.

 

He let out a single, sharp growl.

 

It wasn't amplified by a microphone, but it didn't need to be. The sound resonated at a frequency that hit the human nervous system like an earthquake. It was a guttural, bone-rattling vibration that bypassed the eardrums and spoke directly to the amygdala—the part of the brain responsible for absolute terror.

 

Tenya Iida’s mouth snapped shut. The blood drained from his face. His rigid posture completely collapsed, and he immediately sat back down in his chair, his hands shaking involuntarily. He didn't know why, but his brain had just forcefully instructed him to be quiet or face immediate dismemberment.

 

Present Mic blinked behind his orange glasses, feeling a cold sweat break out on his neck. What the hell was that noise? It sounded like a Jurassic Park sound effect.

 

"O-Okay then!" Mic stammered, quickly recovering his showman persona. "To answer your question, Examinee 7111! The fourth villain is the Zero-Pointer! It's an obstacle! A massive gimmick that rampages in tight spaces! I recommend you all run away from it!"

 

Izuku crossed his arms again. Run away? he thought, snorting dismissively. A true hunter does not run from the biggest beast. The biggest beast yields the best meat.

 

"THAT'S ALL FROM ME!" Mic shouted. "PLUS ULTRA! NOW GATHER AT YOUR DESIGNATED BATTLE CENTERS!"

 

 

 

 

Battle Center B was a massive, sprawling mock cityscape, surrounded by incredibly tall concrete walls and heavy steel gates. It looked like a genuine slice of Musutafu, complete with high-rises, narrow alleyways, and wide main streets.

 

Outside the gates, a crowd of a few dozen examinees stretched their muscles, adjusted their support gear, and tried to calm their nerves.

 

Izuku stood at the very front of the pack, directly facing the massive steel doors. He didn't stretch. His hyper-dense muscles were always primed, always ready for explosive action. He just stood there, swaying slightly from side to side, his breathing slow and rhythmic.

 

Ochako Uraraka was in the crowd, slapping her own cheeks to hype herself up. She saw the giant boy standing at the front. She remembered his gentle purr. Maybe I should go say thank you properly... he looks intimidating, but he saved me.

 

She took a step toward him.

 

A heavy hand clamped down on her shoulder. She turned to see Tenya Iida, looking pale but resolute.

 

"I wouldn't approach him if I were you," Iida whispered tensely. "Look at him. He's entirely focused on the trial ahead. Any interference would be a slight to his concentration. Furthermore... he is terrifying."

 

Ochako gulped, nodding slightly, and stepped back.

 

High above the gates, in a massive observation tower, Present Mic stood at a control console. He looked down at the examinees. He saw the tension. He saw them waiting for a countdown.

 

"START!" Mic screamed over the loudspeakers.

 

The examinees jumped. "Wait, what?" someone yelled. "Where's the countdown?"

 

"THERE ARE NO COUNTDOWNS IN REAL LIFE! RUN, RUN, RUN!"

 

Before the other students could even process the command, a sound like a cannon blast echoed in front of the gates.

 

KRA-KOOOOM!

 

The students shrieked, covering their faces as a massive cloud of dust and pulverized concrete exploded outward.

 

When the dust cleared a second later, the giant was gone.

 

Where Izuku had been standing, two deep craters were gouged into the reinforced pavement.

 

Inside the mock city, Izuku was already three blocks deep.

 

He had dropped to all fours the instant the word "Start" registered in his ears. To Izuku, running on two legs was for endurance and walking. But for hunting? For explosive, predatory speed? The four-limbed dash was the ultimate technique.

 

His knuckles barely grazed the asphalt as his legs pistoned with unimaginable force. He moved like a green missile, his body cutting through the air so fast that the sheer wind pressure shattered the glass windows of the mock buildings as he passed them.

 

He didn't use One For All. He didn't need the Alpha's lightning yet. This was just his natural, prehistoric physiology at work.

 

Izuku sniffed the air. He smelled the ozone, the hot oil, and the static electricity of the metallic beetles.

 

He rounded a corner, his bare feet tearing chunks of asphalt from the road to act as brakes, and skidded to a halt in the center of an intersection.

 

Surrounding him were four Villain Bots. Two 1-pointers, a 2-pointer, and a massive, tank-like 3-pointer. Their red optical sensors locked onto him.

 

"Target acquired," the robotic voices droned in unison. "Commencing elimination protocol."

 

The 1-pointers raised their machine-gun-like appendages, preparing to fire rubber bullets.

 

Izuku grinned. The wide, terrifying, ear-to-ear grin of an apex predator.

 

He didn't dodge. He didn't seek cover.

 

He lunged.

 

He closed the fifty-foot gap to the first 1-pointer in less than a blink of an eye. He didn't throw a punch. He utilized a technique he had perfected on the rusted refrigerators of Dagobah Beach.

 

The Prehistoric Tackle.

 

Izuku drove his massive, sloping shoulder directly into the center mass of the robot.

 

The collision was catastrophic. The laws of physics dictated that an organic body should shatter against solid steel armor. But Izuku’s bone density was infinitely higher than the robot's cheap alloy.

 

The 1-pointer didn't just break; it folded. The steel chassis crumpled inward like a stepped-on soda can. The sheer kinetic transfer of Izuku's four-hundred-pound frame moving at near-mach speeds caused the robot to violently explode into a shower of sparks and twisted metal, the top half severing entirely from the treads.

 

"One," Izuku grunted, doing his best to keep track of the Alpha's numbers.

 

The second 1-pointer opened fire. Rubber bullets pinged against Izuku's thick skin. To a normal teenager, they would leave severe bruises. To Izuku, it felt like being lightly pelted with dried peas. It was annoying.

 

Izuku swiped his massive arm in a backhand motion. His thick, calloused knuckles struck the robot's sensory array. The head of the robot simply popped off its neck joint, spinning through the air and crashing through a third-story window.

 

The 2-pointer, resembling a mechanical scorpion, lunged forward with its tail stinger.

 

Izuku caught the heavy steel stinger in his bare hands. The robot's hydraulics whined, trying to push forward, but it was like a toy trying to push a mountain. Izuku's muscles bulged. He didn't just stop the strike; he pulled.

 

He yanked the 2-pointer forward, throwing it completely off balance. As the machine stumbled, Izuku pivoted on his heel and delivered a devastating axe kick to the robot's central chassis. His bare heel cleaved through the armor plating, shattering the internal engine.

 

The 3-pointer was the only one left. It fired a real, albeit low-yield, missile at him.

 

Izuku didn't step back. He let out a roar, leaping forward. He met the missile mid-air, batting it aside with a heavy forearm. The explosion detonated against a nearby building, the heat washing over Izuku’s skin like a warm breeze.

 

He landed directly on top of the 3-pointer's main gun barrel. The machine tried to elevate to shake him off, but Izuku’s sheer weight pinned the hydraulic servos down.

 

Izuku reached down, his thick, claw-like fingers digging into the seams of the steel armor plating. He tightened his grip, his muscles cording into thick, vascular knots, and pulled.

 

With a screech of tearing metal, Izuku ripped the entire top chassis off the tank, exposing the sparking, whirring wires beneath. He grabbed a handful of the main power cables and, just to be sure the beast was dead, bit clean through them with his fangs.

 

He spat the sparking wires out, wiped his mouth, and stood atop the ruined machine, puffing his chest out. He let out a triumphant, echoing howl to assert his dominance over the intersection.

 

Meanwhile, at the entrance gates, the other students had finally arrived at the city limits. They stared down the main road.

 

It looked like a war zone. Flaming robot parts littered the streets. Buildings were cracked from sonic booms.

 

"What... what happened here?" Ochako whispered, horrified.

 

Iida pushed his glasses up his nose, a drop of sweat rolling down his cheek. "It seems... the path has been cleared. And whatever cleared it... is very, very dangerous."

 

 

 

 

Deep within the bowels of U.A. High School, in a dimly lit, highly secure observation room, the faculty of the academy sat before a massive wall of monitors.

 

Pro heroes like Midnight, Snipe, Ectoplasm, and Cementoss watched the screens, taking notes on clipboards. In the center of the room, sitting in a plush leather chair, was Principal Nezu—a highly intelligent chimera of a mouse, dog, and bear, sipping calmly from a teacup.

 

Standing behind Nezu was Toshinori Yagi, in his skeletal form, wearing a baggy yellow suit. He was practically vibrating with anticipation.

 

"We have an interesting crop this year," Midnight commented, twirling her whip. "That boy with the explosion quirk in Center A is racking up points with terrifying efficiency. He's got great combat instincts."

 

"The girl with the gravity quirk in Center B is also showing good situational awareness," Snipe added, pointing at a screen. "Using the floating debris as projectiles. Smart."

 

"Yes, yes, they are all very promising," Eraserhead—Shota Aizawa—drawled from his sleeping bag in the corner of the room. "But can we talk about the elephant in the room? Or rather, the Tyrannosaurus Rex?"

 

Aizawa hit a button on a remote. The main, central monitor shifted, pulling up a drone feed from Battle Center B.

 

The room fell completely silent.

 

The monitor showed Izuku Midoriya. He was currently holding a 2-pointer by its mechanical legs, spinning like an Olympic hammer-thrower, and hurling the multi-ton machine through the air to crush a group of three 1-pointers down the street.

 

Izuku didn't look tired. He looked like he was at a playground. He was grinning wildly, bouncing on the balls of his feet, his thick green mane flying in the wind.

 

"Examinee number 7111. Izuku Midoriya," Nezu read from a file, taking a delicate sip of his tea. "Quirk registered as 'Prehistoric Physiology'. A mutation class."

 

"Mutation?" Ectoplasm muttered, his mechanical jaw dropping slightly. "I've seen gigantification and strength mutations, but this... the boy is destroying heavily armored combat droids with his bare hands. He isn't using any elemental boosts. He's not using impact dispersion. He's just... hitting them really, really hard."

 

"Look at the telemetry data on the drones," Snipe said, his voice laced with disbelief. "When he sprints on all fours, he's peaking at ninety miles per hour. The kinetic force he's generating on impact is enough to flatten a city block. If he hits a human with that kind of force..."

 

"He won't," Toshinori spoke up, his voice raspy but firm.

 

The other teachers turned to look at him.

 

"He may look like a monster," Toshinori said, gripping the railing, his eyes locked onto the screen showing his successor. "He may fight like a wild beast. But I have seen his heart. He possesses an innate, unwavering instinct to protect. He knows the difference between a machine and a life."

 

Aizawa narrowed his dark eyes, watching the green giant tear a robot's head off and casually toss it over his shoulder. "Instincts are dangerous, All Might. An animal that strong cannot be controlled by a classroom. If he loses his temper, who stops him?"

 

"He doesn't need to be controlled," Nezu chirped happily. "He needs to be guided. U.A. is not a zoo, Eraserhead. It is a place of learning. If this boy has the potential to be a hero, it is our duty to teach him how to exist in this world. And frankly... I am utterly fascinated by him."

 

Nezu placed his teacup down and reached out with a small, furry paw toward a large, red button on the console.

 

"Let us see how the examinees respond to true adversity," Nezu said, a slightly sadistic glint in his black eyes. "Let's introduce the Alpha of the arena."

 

Nezu pressed the red button.

 

 

 

 

Izuku stood in the center of a wide plaza, wiping a smear of black machine oil from his cheek. He was surrounded by a graveyard of crushed metal. He had lost count of how many beetles he had hunted. The numbers stopped making sense after twenty.

 

He took a deep breath, letting the scent of burning oil and ozone fill his lungs. This was fun. This was a good hunt. The Matriarch would be proud.

 

Suddenly, the ground beneath his feet shifted.

 

It wasn't a slight tremor. It was a localized earthquake. The loose pebbles on the asphalt began to dance. The crushed husks of the robots rattled against one another.

 

Izuku’s ears pinned back. His head snapped toward the north end of the city.

 

A shadow fell over the plaza, blocking out the morning sun.

 

With a deafening roar of grinding gears and roaring hydraulics, a massive, building-sized hand smashed through a row of high-rises. The buildings crumbled like brittle crackers.

 

The Zero-Pointer emerged from the dust.

 

It was a colossal, monolithic machine, easily towering over a hundred feet tall. Its single, glowing red optic scanned the city like the eye of an angry god. Its treads crushed entire streets into powder.

 

Down the street, the other examinees, who had been trying to pick off the scraps Izuku had left behind, froze in absolute terror.

 

"Is that... the Zero-Pointer?!" a boy with a hardening quirk screamed.

 

"It's huge! What the hell is the school thinking?!"

 

"Run! It's not worth any points! Just run!"

 

The students turned and fled in a blind panic, scrambling over each other to get away from the mechanical titan.

 

Izuku didn't run.

 

He stood perfectly still in the center of the plaza. He tilted his head back, staring up at the monolithic machine.

 

To the other students, it was a terrifying, unfair obstacle designed to test their evasive abilities.

 

To Izuku Midoriya, reincarnation of a prehistoric apex predator, it was the greatest challenge he had ever seen.

 

For the first time in his life, Izuku was looking at something bigger than him. Something heavier. Something that radiated a sense of overwhelming, crushing dominance. It was the mechanical equivalent of a Brachiosaurus.

 

Izuku didn't feel fear. He felt a profound, burning ecstasy.

 

His lips curled back into a grin so wide it almost looked painful. His emerald eyes dilated until they were entirely black, consumed by the thrill of the hunt. He let out a low, rumbling chuckle that vibrated in the air.

 

He was going to tear that thing to pieces.

 

He took a step forward, preparing to drop into his sprinting stance, when his acute hearing caught a sound beneath the grinding of the treads.

 

"Ow... help... my leg..."

 

Izuku’s head snapped to the right.

 

About sixty feet away, near the path of the advancing Zero-Pointer, a girl was trapped beneath a massive slab of concrete rubble that had fallen from a destroyed building. It was the clumsy bird. Ochako Uraraka. She was struggling desperately to push the rubble off, her face pale with pain and fear.

 

The Zero-Pointer's massive tread was rolling directly toward her. In less than ten seconds, she would be crushed.

 

Izuku’s feral grin vanished instantly.

 

The thrill of the hunt evaporated, replaced by an overwhelming, explosive surge of protective rage. A member of the pack was in danger. The massive beast was threatening a weak, fragile cub.

 

Izuku didn't rely on his physical mutation alone this time. He didn't want to just hit the machine. He wanted to obliterate it.

 

He called upon the Alpha's torch.

 

One For All.

 

Deep within his chest, the stockpile of power roared to life. Izuku didn't bottleneck it at five percent. His prehistoric biology demanded more. He opened the floodgates, forcefully dragging twenty percent of the Alpha's raw, unadulterated power into his hyper-dense musculature.

 

ZZZZZT!

 

Brilliant, blinding green lightning erupted from his skin. The air pressure around him spiked violently, creating a localized gale-force wind that blew the dust and debris away from him in a perfect circle. His already massive muscles visibly expanded, veins glowing with the ancient power.

 

Izuku didn't drop to all fours. He crouched low on his two feet, his thick legs coiling like massive hydraulic springs.

 

He pushed off.

 

The entire plaza cratered beneath him, an explosion of concrete and earth shooting fifty feet into the air.

 

Izuku broke the sound barrier instantly. He crossed the sixty feet to Ochako in a microsecond, passing over her like a green blur.

 

The Zero-Pointer raised its massive, multi-ton foot, preparing to stomp down on the area where Ochako lay trapped. The steel appendage eclipsed the sun, casting a shadow of certain death.

 

Izuku intercepted it.

 

He leapt directly into the path of the falling foot. He didn't throw a punch to deflect it. He didn't try to dodge.

 

Izuku raised his arms, crossed them above his head, and caught the foot of the Zero-Pointer.

 

KRAAAAAAAAASH!

 

The collision generated a shockwave that blew every remaining window in a five-block radius to powder. The sheer kinetic energy of the giant robot's stomp met the immovable object of Izuku Midoriya’s reinforced body, empowered by One For All.

 

In the observation room, the faculty jumped out of their seats.

 

"He caught it?!" Snipe yelled, his jaw dropping. "That thing weighs thousands of tons!"

 

Izuku was suspended mid-air for a fraction of a second, the robot's foot pressing down on him. Then, gravity asserted itself. Izuku slammed down into the street directly in front of Ochako, his bare feet sinking three feet deep into the solid asphalt.

 

He was holding the robot's foot up like Atlas holding the sky. The hydraulics of the machine whined in protest, the gears grinding as they tried to force the foot down.

 

Izuku’s muscles strained. The green lightning sparked violently around him. His fangs were bared in a snarl of pure exertion. But his joints didn't buckle. His prehistoric cartilage held firm. He was built for this.

 

Ochako stared up from the rubble, her eyes wide with sheer, unadulterated awe. The giant boy was standing over her, holding back a mountain of steel with his bare hands. He looked back at her, his emerald eyes burning with power, and gave her a sharp, reassuring nod.

 

Pack is safe.

 

Izuku turned his attention back to the machine above him.

 

He didn't want to just hold it. He wanted to break it.

 

Izuku shifted his stance, pulling his arms back slightly, allowing the massive foot to drop another inch, absorbing the weight. He dug his feet deeper into the earth, anchoring himself against the bedrock of the city.

 

He wrapped his massive, thick arms around the main hydraulic piston of the robot's ankle.
