What if deku had a walrus quirk

 

The world is not equal.

 

That was the absolute truth that Izuku Midoriya learned at the tender age of four. However, unlike the countless stories of late bloomers or the tragic tales of the Quirkless, Izuku did not learn this truth by being left behind. He learned it by outgrowing the world around him, expanding into a shape that society had not built its doorways, its chairs, or its prejudices to accommodate.

 

It started with a fever.

 

Before the fever, Izuku was a small, round-faced boy with a mop of unruly green hair, big emerald eyes, and an insatiable love for the number-one hero, All Might. He was light enough that his mother, Inko, could effortlessly scoop him up and spin him around the living room while he giggled, clutching his favorite action figure.

 

Then came a Tuesday in late autumn. The weather was turning crisp, the leaves on the ginkgo trees lining the streets of Musutafu shifting to a brilliant gold. Izuku had woken up feeling heavy. Not just sluggish, but fundamentally anchored to the mattress. His skin felt tight, stretching uncomfortably across his small bones. By noon, his temperature had spiked to a terrifying hundred and four degrees.

 

Inko had rushed him to the local clinic, her heart in her throat. The doctors pumped him full of fluids and fever reducers, but the heat radiating from the four-year-old’s body was unnatural. And then, the hunger began.

 

It wasn't a normal childhood appetite. It was a ravenous, echoing void in his stomach. Sitting in the hospital bed, wrapped in thin white blankets, Izuku ate through three trays of hospital food, then cried for more. Inko, terrified but desperate to soothe her child, bought out the hospital vending machines, feeding him rice balls, bread, and caloric gels.

 

Over the next forty-eight hours, the transformation took hold. It was rapid, violent, and undeniable.

 

The boy’s metabolism went into a state of hyper-drive. His small, delicate frame expanded. A thick, incredibly dense layer of subcutaneous tissue—blubber—began to form beneath his skin. His collarbones vanished beneath thick muscles and fat; his neck thickened until it was flush with his jawline. His skin, once soft and prone to scraping when he fell on the playground, grew tough, rubbery, and incredibly resilient.

 

But the most alarming changes were in his face. Izuku spent hours crying, clutching his mouth as a terrible aching pressure built in his upper gums. It felt like his skull was shifting. On the third day, the pressure broke the skin. Two ivory nubs, stark white and hard as diamond, pushed their way through his upper jaw, pressing down over his lower lip. Above his mouth, the skin of his upper lip swelled and thickened, sprouting dozens of stiff, highly sensitive bristles.

 

When the fever finally broke on the fifth day, the child sitting in the hospital bed barely looked like the Izuku Midoriya who had been admitted.

 

He was nearly twice his original weight, incredibly broad, with a pair of emerging tusks and a muzzle of stiff, twitching whiskers. He looked up at his mother with the same wide, innocent, emerald eyes, clutching his All Might figure in hands that were now thick, padded, and heavy.

 

The specialist, a man named Dr. Tsubasa, adjusted his glasses as he looked over the new X-rays. He was a bald man with a bushy mustache, and he didn't look particularly surprised. In a world of Quirks, he had seen children turn into dragons, insects, and living shadow.

 

"Well, Mrs. Midoriya," Dr. Tsubasa said, tapping the glowing film on the lightboard. "The good news is that your son is perfectly healthy. The fever was simply his body's way of surviving the rapid morphological changes required by his Quirk."

 

Inko wrung her hands, her eyes darting between the doctor and her massive, tusked four-year-old. "H-His Quirk? But my husband breathes fire, and I can attract small objects. Neither of us has a... a mutant-type Quirk."

 

"Genetics can be a funny thing," the doctor replied smoothly, pulling up a secondary chart. "Quirks are the result of complex genetic sequencing. Sometimes, recessive traits from generations past combine, or a completely spontaneous mutation occurs. In Izuku's case, his Quirk has fundamentally rewritten his physiology. We classify this as a Heteromorphic, or Mutant-type Quirk."

 

The doctor turned to look at Izuku. "I've registered his Quirk under the name 'Walrus.' The scientific name is Odobenus rosmarus. His body has generated an incredibly dense layer of blubber for thermal regulation and kinetic absorption. His bone density has tripled to support the new weight. Those tusks will continue to grow as he ages, and those vibrissae—the whiskers—are highly advanced sensory organs. He is, for all intents and purposes, built to survive the crushing depths and freezing temperatures of the arctic ocean."

 

Inko looked at Izuku. Izuku blinked, his new whiskers twitching violently as a draft from the air conditioning vent hit them. To him, the air felt loud. Every current of wind in the room painted a picture against his upper lip.

 

"A... a walrus," Inko whispered, the word feeling heavy on her tongue.

 

"I wanna be a hero!" Izuku chirped, his voice sounding slightly muffled around the new, aching nubs of ivory in his mouth. He held up his All Might toy. "Like him! Can I be a hero with a walrus Quirk, doctor?"

 

Dr. Tsubasa’s expression softened, but a shadow of clinical pity crossed his eyes. "Well, Izuku... Heroism is a tough road. Your Quirk gives you excellent durability and, presumably, great advantages in water. But on land? Your body is going to be incredibly heavy. You aren't going to be fast. And... well, heteromorphic Quirks like yours draw a lot of stares. The hero industry is highly reliant on public image."

 

He didn't say the word out loud, but it hung in the air: Ugly.

 

Inko caught the implication immediately. Tears welled in her eyes, not because her son had changed, but because she knew how cruel the world was to those who looked different. The heroes on the billboards—All Might, Endeavor, Best Jeanist—they were traditionally handsome, human-passing, sleek, and dynamic. Mutant heroes existed, but they were often relegated to niche sidekick roles, heavily stereotyped, or pushed into the background.

 

Inko walked over to the bed, wrapping her arms around her son’s massive, broad shoulders. It took both her arms just to reach around him now.

 

"You're going to be a wonderful hero, Izuku," she sobbed, burying her face into his thick, rubbery shoulder.

 

Izuku didn't fully understand the doctor's hesitation, nor his mother's tears. He just knew he finally had a Quirk. He had power. He was going to save people with a smile.

 

 

 

The illusion of equality shattered completely when Izuku returned to kindergarten.

 

Before his Quirk manifested, Izuku had been Katsuki Bakugo’s shadow. Bakugo was fiery, confident, and gifted with a flashy, powerful Explosion Quirk. The other kids flocked to him. When Izuku returned to school, he expected the same treatment. He had a Quirk now! A big one!

 

He stepped onto the playground, the sand crunching heavily beneath his custom-made, extra-wide red sneakers. At four years old, he already outweighed the teachers. His green hair sat atop a thick, neckless frame, his tusks poking out over his bottom lip, his whiskers bristling in the autumn wind.

 

The playground went dead silent.

 

Bakugo, who had been showing off small pops of nitroglycerin in his palms, stopped. He stared at the lumbering, massive boy approaching him.

 

"Kacchan!" Izuku called out, waving a thick, padded hand. His voice was the same—soft, slightly timid, and high-pitched—which created a jarring disconnect with his hulking, beastly appearance. "I got my Quirk! Look!"

 

A boy with elongated fingers pointed at him. "Whoa... Midoriya got huge! He looks like a monster!"

 

"He's got teeth coming out of his face!" a little girl squeaked, hiding behind the slide.

 

Bakugo’s crimson eyes narrowed. He marched up to Izuku. Even though Izuku was now significantly wider and slightly taller, Bakugo held his ground, his pride demanding dominance.

 

"What the heck is wrong with your face, Deku?" Bakugo demanded.

 

"It's my Quirk!" Izuku smiled, though the tusks made the smile look intimidating rather than friendly. "The doctor called it Walrus! I'm super strong and I have armor!"

 

"Armor?" Bakugo sneered. He shoved his hands out, pressing against Izuku’s chest. "You just look fat! You look like a giant, ugly balloon!"

 

Izuku’s smile faltered. His whiskers drooped. "I-I'm not fat, Kacchan. It's blubber. It protects me."

 

"Yeah, right!" Bakugo stepped back and sparked his palms. "Let's see if it protects you from this!"

 

Without warning, Bakugo lunged, slamming a miniature explosion directly into Izuku’s chest. The other children gasped. Usually, when Bakugo used his Quirk on someone, they fell over crying.

 

The smoke cleared.

 

Izuku hadn't moved an inch. His feet were planted firmly in the sand. His green kindergarten uniform was scorched, but the skin beneath wasn't even reddened. The kinetic force of the blast had rippled across his thick blubber and dissipated instantly into his mass. The heat had barely registered against tissue designed to survive sub-zero waters.

 

Izuku looked down at his chest, then back up at Bakugo, his eyes wide. "It didn't hurt..." he murmured, genuinely amazed.

 

For a split second, Bakugo looked utterly shocked. His ultimate weapon, his pride and joy, had done absolutely nothing. And it had done nothing to Deku, the weakest, crybaby kid in the neighborhood.

 

That shock quickly boiled over into intense, irrational fury. Bakugo’s pride couldn't handle the idea of an immovable object standing in the way of his unstoppable force.

 

"You're just a freak!" Bakugo yelled, his face turning red. "You're a fat, gross, useless freak! You think being a big, dumb blubber-bag makes you a hero? You can't even run fast! I saw you waddling over here! You'll never catch a villain!"

 

The words hit harder than the explosion ever could. They pierced straight through the impenetrable blubber, bypassing his mutant armor to strike directly at his soft, fragile heart.

 

Izuku’s eyes welled with tears. He looked down at his massive hands, then at his thick belly, then felt the sharp edges of his tusks.

 

"I-I can be a hero..." Izuku whimpered, tears spilling down his cheeks.

 

"Yeah, right, Blubber Boy!" Bakugo laughed, turning to his lackeys. "Deku's not Quirkless, he's just useless! Blubber Boy! Blubber Boy!"

 

The other kids chimed in, pointing and laughing. Izuku stood there, an immovable mountain of a child, crying silently as the world drew its new lines around him. He wasn't bullied for being empty. He was bullied for taking up too much space.

 

 

 

Ten years passed.

 

The transition from childhood to adolescence is difficult for anyone, but for Izuku Midoriya, it was a constant, exhausting battle of logistics. By his fourteenth birthday, Izuku stood an imposing six feet, two inches tall. He weighed just north of three hundred and fifty pounds. But to call him "fat" would be an immense misunderstanding of mutant biology.

 

Underneath the layers of dense, shock-absorbing blubber lay a foundation of terrifyingly thick muscle and bone. His legs were akin to tree trunks, built to propel his massive weight forward. His torso was a barrel of raw power. His hands were large enough to palm a basketball with ease, the skin heavily calloused.

 

But it was his head that drew the stares. His green hair was swept back, blending into a thick neck. His tusks had grown magnificently, curving downward from his upper jaw to rest against his chest, measuring nearly fourteen inches long. They were a pristine, deadly ivory. Surrounding them was a thick mustache of pale, stiff vibrissae—his sensory whiskers—that constantly twitched, reading the air currents, temperature changes, and micro-vibrations in his environment.

 

Living in a world designed for standard humanoid bodies was a daily trial.

 

Every morning started with a careful routine. Izuku would wake up—usually on a custom reinforced mattress because he had broken three standard beds in middle school simply by rolling over. He would go to the bathroom, ducking under the doorframe to avoid clipping his tusks. Brushing his teeth took twice as long; standard teeth required normal brushing, but his tusks required specialized polishing and filing. He had to gently file the tips every week to blunt them, terrified of accidentally impaling someone on a crowded train.

 

Then came the heat. Humans didn't realize how hot the world was. For someone wrapped in a permanent, biological winter coat, the Japanese summers were agonizing. Izuku took freezing cold showers just to bring his core temperature down. He wore specialized, lightweight cooling undershirts imported from hero-support companies, tearing through his mother’s budget.

 

"Izuku, breakfast is ready!" Inko's voice called from the kitchen.

 

Izuku emerged from his room, dressed in his Aldera Junior High uniform. Finding clothes was a nightmare. The black gakuran uniform had to be custom-tailored by a shop specializing in heteromorphic Quirks. It was stretched tight across his incredibly broad chest, the collar left completely unbuttoned because his neck was too thick for it to close.

 

"Morning, Mom," Izuku rumbled. His voice had dropped an octave or two during puberty, carrying a deep, resonant, oceanic timbre. Despite the deep voice and intimidating appearance, he still held his shoulders hunched inward, desperately trying to make himself look smaller, less imposing, less in the way.

 

He sat at the dining table. The chair beneath him was reinforced with steel braces. Inko placed a massive bowl of rice, an entire side of grilled salmon, and a huge bowl of miso soup in front of him. This was just his first breakfast.

 

"Did you pack your cooling packs, sweetie?" Inko asked, pouring herself a much smaller cup of tea. She looked at her son with nothing but unconditional love. While the rest of the world saw a beast, she only saw her sweet, analytical little boy.

 

"Yeah, they're in my bag," Izuku said, carefully maneuvering his chopsticks around his right tusk to take a bite of fish. Eating in public was always awkward, but at home, he had a system. "The weather report said it's going to be twenty-eight degrees today. It's gonna be brutal during P.E."

 

"Just take it easy," Inko cautioned. "Don't push yourself too hard in the heat. You know what Dr. Tsubasa said about hyperthermia."

 

"I know, I know." Izuku smiled, his whiskers curling upward cheerfully.

 

After finishing a meal that could feed a family of four, Izuku grabbed his bright yellow backpack. He slung it over one massive shoulder, gave his mom a gentle, careful hug, and headed out the door.

 

The walk to Aldera Junior High was a masterclass in ignoring the public.

 

As Izuku lumbered down the sidewalk, people instinctively parted for him. It was a biological reaction; when a three-hundred-and-fifty-pound wall of muscle and tusks walks toward you, your brain tells you to move. Mothers pulled their children closer. Businessmen stepped into the street to give him a wide berth. Teenagers pointed and whispered.

 

Look at that guy.

Is his Quirk a boar? No, a walrus maybe?

Gross. Look at those teeth. Imagine having to kiss that.

He looks like a villain. Think he's a villain?

 

Izuku kept his eyes glued to the pavement, his incredibly sensitive whiskers picking up the low whispers carried on the wind. He heard everything. His hearing was adapted for echolocation and underwater communication; human whispers were like shouts to him.

 

He gripped the strap of his backpack tighter, his knuckles turning white. To distract himself, he slipped his free hand into his bag and pulled out a burnt, slightly battered notebook. Hero Analysis for the Future, Vol. 13.

 

Unlike his peers, who idolized flashy elemental Quirks or super-strength, Izuku’s notebooks were highly specialized. They were shrines to the marginalized, the heteromorphs, and the aquatic.

 

While All Might was still his absolute idol, Izuku knew he would never fight like All Might. All Might was agile. He danced through the air. Izuku could barely run a fifty-meter dash in under nine seconds on land. His body was a biological tank. It was built for endurance, absolute defense, and devastating close-quarters grappling.

 

So, he studied those who fought like him.

 

Page 42 was dedicated to Gang Orca. The Killer Whale hero was a mutant like Izuku, massive and intimidating. Izuku had filled the margins with notes on Gang Orca’s land combat. Orca relies on his sheer physical weight to anchor himself, Izuku had written. He uses his sonar as a localized sonic attack to paralyze faster opponents, making up for his lack of agility.

 

Page 58 featured Selkie. The spotted seal hero was faster on land than Gang Orca, but his true domain was the water. Izuku idolized Selkie's rescue operations. Water makes weight irrelevant. In the water, hydrodynamics matter more than gravity. If I can fight in aquatic environments, my speed will increase by 400%.

 

But the hero Izuku studied the most intensely was the Kansai-based pro, Fat Gum. BMI Hero: Fat Gum didn't have an animal mutation, but his body composition was the closest analog Izuku had to his own blubber. Fat Gum absorbed kinetic energy, sinking opponents' attacks into his body fat before transferring it into raw power.

 

Izuku had spent hours analyzing this. My blubber isn't quite like Fat Gum's. I can't store kinetic energy and redirect it. But I can absorb it. Blunt force trauma, temperature extremes, and low-caliber ballistics have virtually no effect on my internal organs. If I can't dodge an attack, the optimal strategy is to take the hit, trap the opponent's limb in the folds of my blubber, and use my superior weight to grapple them to the ground.

 

He was so engrossed in mentally diagramming a grappling counter to an overhand right that he didn't notice the crowd gathered ahead at Tatooin Station until his whiskers vibrated with the sonic boom of an explosion.

 

Izuku snapped his notebook shut and pushed his way to the front of the crowd. With his immense height, he easily saw over the heads of the onlookers.

 

A villain with a gigantification Quirk was rampaging across the train tracks. Pro heroes Kamui Woods and Death Arms were struggling to contain him. Izuku watched with rapt attention as a new hero, Mt. Lady, debuted with a massive canyon-cannon kick.

 

As the crowd cheered, Izuku’s analytical mind was firing on all cylinders. He noted Kamui’s bindings, Mt. Lady’s lack of collateral damage awareness, and Death Arms’ center of gravity. He scribbled furiously in his notebook, muttering aloud.

 

"Kamui Woods' pre-emptive binding was smart, but against an opponent with expanding mass, the tensile strength of the wood needs to exceed the opponent's growth rate. Mt. Lady has the advantage in sheer weight, but her lack of armor leaves her vulnerable to sharp debris. If she wore reinforced kneepads..."

 

"Hey, big guy, what are you muttering about?" a man next to him asked, looking up at Izuku’s tusks with a mix of awe and slight unease. "You a hero fan?"

 

Izuku flinched, instinctively hunching his shoulders. "A-Ah, yes! Just... taking notes. For my future."

 

"With a body like that, you could probably take that giant villain head-on!" the man laughed, slapping Izuku’s thick arm. It felt like slapping a tire. "You built like a brick house, kid!"

 

Izuku offered a polite, nervous smile, his whiskers twitching. "T-Thank you. I want to be a hero."

 

He didn't stick around to see the man's reaction, turning and lumbering away toward school. The man had meant it as a compliment, but it stung in a strange way. People saw his body and assumed he was meant to be a brute. A brawler. A meat-shield. Nobody looked at the massive, tusked monster and thought: There goes a brilliant tactical mind.

 

 

 

Aldera Junior High was a hotbed of adolescent cruelty. And today was the day that cruelty would reach its peak.

 

Class 3-C was loud, rowdy, and hot. The morning sun beat against the windows, and the lack of air conditioning meant the classroom felt like a sauna. Izuku sat at his desk near the back. Technically, he sat on a stool he had brought from home because the standard wooden chairs snapped under his weight, and he rested his notebook on a desk that was propped up on wooden blocks to accommodate his massive thighs.

 

He was sweating profusely, a damp rag draped over the back of his thick neck to keep his temperature down.

 

At the front of the room, Mr. Yamada, their homeroom teacher, stood holding a stack of career aptitude forms.

 

"Since you're all third years, it's time for you to think seriously about your futures!" the teacher announced, his voice carrying over the chatter. He suddenly grinned, tossing the papers into the air. "But who am I kidding? You're all planning to go into the hero course, right?!"

 

The classroom erupted. Students showed off their Quirks—stretchy limbs, glowing eyes, minor telekinesis.

 

"Yes, yes, you all have wonderful Quirks!" the teacher laughed. "But remember, using your powers at school is against the rules!"

 

"Sensei! Don't lump me in with these background characters!"

 

The voice, arrogant and booming, cut through the noise. Izuku didn't need to look up. His whiskers felt the sudden spike in temperature and ozone in the air. Katsuki Bakugo was leaning back in his chair, his feet resting on his desk, an explosive smirk on his face.

 

"I'm destined for greatness!" Bakugo declared, sparking his palms. "I aced all the mock tests. I'm the only one from this crappy middle school who has a shot at U.A. High School! I'm gonna surpass All Might and become the top hero!"

 

The class murmured in awe. U.A. High School was the pinnacle of hero education. Its acceptance rate was abysmal.

 

"Oh, right," the teacher said, looking down at his clipboard. "Midoriya, you're also applying for U.A., aren't you?"

 

The classroom went dead, suffocatingly silent.

 

Izuku froze. His heart hammered against his ribcage, thick and heavy. He slowly sank into himself, wishing his massive body could somehow vanish into the floorboards.

 

For a second, nobody spoke. Then, someone snickered.

 

Then, the entire class burst into uproarious, mocking laughter.

 

"Midoriya?! Are you kidding me?!"

"The Walrus?! At U.A.?!"

"What's he gonna do, sit on the villains?! Crush them with his fat?!"

"U.A. is for heroes, not aquarium attractions!"

 

Izuku squeezed his eyes shut, his hands balling into massive, meaty fists on his desk. He was used to this. He had endured it for ten years. He told himself to just breathe, to let it wash over his blubber like cold water.

 

BOOM!

 

A violent explosion shattered the laughter. Bakugo launched himself out of his chair, using his explosions to propel himself across the room. He slammed both of his smoking hands down onto Izuku’s desk.

 

The desk groaned in protest. Izuku looked up, his green eyes meeting Bakugo’s furious crimson.

 

Bakugo hadn't changed much in personality, but physically, he was lean, muscular, and lethal. However, looking at them side-by-side, the contrast was comical. Bakugo was aggressively leaning over a boy who was six inches taller and over twice his weight. Bakugo looked like a tiger trying to intimidate a hippo.

 

"Listen to me, Blubber Boy," Bakugo growled, his palms smoking, threatening to scorch the wood. "You're a D-lister. A slow, heavy, ugly freak. You think they want some lumbering water-balloon in the U.A. hero course? You wouldn't last two seconds in a real fight. You're just a moving target."

 

"T-There's no rule saying I can't apply, Kacchan," Izuku stammered, his deep voice trembling. "M-My Quirk isn't useless. I have high defensive capabilities. I-I can do rescue... I want to try."

 

"Try?!" Bakugo's eyes widened with manic fury. "You think you can stand in the same arena as me?! You think you can rub shoulders with the best?!"

 

Bakugo’s right hand whipped out, snatching the Hero Analysis notebook off Izuku’s desk.

 

"Ah! Kacchan, please give that back!" Izuku reached out, his massive hand moving with surprising speed, but Bakugo was faster.

 

Bakugo held the notebook up, pressing his palms flat against the covers. "Hero Analysis for the Future? More like Delusions of a Freak."

 

With a loud crack, Bakugo detonated his palms. The heat instantly scorched the covers, burning the pages, destroying months of careful, meticulous notes on marine and mutant heroes. Izuku flinched, not from the heat, but from the destruction of his hard work.

 

Bakugo tossed the smoking, ruined notebook out the open third-story window. It fluttered down toward the koi pond below.

 

"If you really want to be a hero so badly, Deku," Bakugo sneered, using the childhood nickname that meant 'useless,' "there might be a faster way. Pray you're born with a better Quirk in your next life, and take a swan dive off the roof!"

 

Silence fell over the classroom again. Even Bakugo’s lackeys looked slightly uncomfortable. Telling someone to kill themselves crossed a line.

 

Izuku just sat there. His tusks gleamed in the sunlight. His whiskers twitched violently, sensing the tension, the heat of Bakugo’s palms, the stale air of the room. A dark, heavy shadow fell over his eyes.

 

For a terrifying, fleeting second, Bakugo saw the muscles in Izuku’s massive arms tense. He realized, with a sudden prickle of primal instinct, that if Izuku decided to stand up and swing one of those tree-trunk arms, Bakugo would be launched through the concrete wall. The sheer kinetic force of a three-hundred-pound mutant putting his weight into a blow would shatter his bones.

 

But Izuku didn't move.

 

The shadow lifted. Izuku’s shoulders slumped. He looked away, his eyes locking onto the empty space where his notebook used to be.

 

Bakugo clicked his tongue, masking his momentary spike of fear with a sneer. "Whatever. Let's go," he muttered to his friends, turning his back on the giant and walking out of the classroom as the final bell rang.

 

Izuku sat alone in the heat of the classroom for a long time.

 

 

 

The walk home felt heavier than usual, and for a boy carrying nearly two hundred pounds of dense blubber and muscle, that was saying something.

 

Izuku had retrieved his notebook from the koi pond. It was soaked, scorched, and half-eaten by the fish. He tried to brush the dirt off the cover, but the water had smeared the ink inside. His careful diagrams of Fat Gum's center of gravity were ruined.

 

"Idiot," Izuku whispered to himself, his deep voice echoing slightly in the quiet afternoon air. "What am I doing?"

 

He stopped walking. He was passing by a large storefront window. The glass was tinted, turning it into a makeshift mirror.

 

Izuku turned his head, looking at his reflection.

 

He didn't see the heroic spirit that burned in his chest. He saw exactly what society saw.

 

He saw a monster.

 

He looked at the way his shoulders sloped into a thick, neckless torso. He looked at the massive, protruding ivory tusks that made it impossible to wear a normal face mask or eat a sandwich without cutting it into pieces. He looked at his hands, which were so thick and padded that he struggled to hold a pencil properly without breaking it.

 

"A walrus," he murmured.

 

Walruses were not graceful. They were not beautiful. They were sluggish, blundering creatures that dragged themselves across the ice, relying purely on fat and tusks to survive. They were the butt of jokes. They were the punchline in cartoons.

 

Why had he been cursed with this body, but blessed with the heart of a hero? Why did he have to desire the sky when he was built for the bottom of the ocean?

 

"It's not fair," he whispered, pressing one of his massive hands against the glass. The reflection of his padded palm obscured his face. "All Might saves people with a fearless smile. When people see my smile... they just see weapons."

 

He thought of Bakugo’s words. A slow, heavy, ugly freak.

 

Was he right? The hero rankings were essentially a popularity contest combined with a combat metric. Could a heteromorph like him, whose very appearance unsettled people, ever make it into the Top Ten? Gang Orca was currently the number eleven hero, and he was constantly ranked number three on the list of "Heroes Who Look Like Villains."

 

Izuku closed his eyes. The ambient sounds of the city washed over him. He focused on his vibrissae. His whiskers painted a map of his surroundings. He could feel the vibration of a car driving two streets over. He could feel the slight drop in barometric pressure signaling rain later that evening. He could feel the warmth of the setting sun on his thick skin, a heat that would have exhausted a normal person, but which his body effortlessly managed.

 

No.

 

Izuku opened his eyes. The emerald green burned with a stubborn, quiet defiance.

 

I am not useless.

 

Bakugo was wrong. The world was wrong.

 

He wasn't All Might. He couldn't blast through the air with a shockwave. He couldn't create explosions. He couldn't freeze a building.

 

But he was an immovable object.

 

He remembered the Sludge Villain from the news a few weeks ago, a terrifying amorphous monster that had suffocated a man. He remembered how heroes with physical attacks couldn't touch it.

 

Izuku looked at his reflection one more time. He squared his broad shoulders, standing at his full, imposing height of six-foot-two. He stopped hunching. He let his chest expand.

 

I am heavy. I am armored. If a building falls, I can catch it. If a villain strikes, I can take it. I am the shield that stands between the innocent and the fire.

 

He squeezed the wet notebook in his hand, careful not to crush it completely with his grip strength.

 

I'm going to U.A. High School. I'm going to show Kacchan, and Mr. Yamada, and everyone else. A hero isn't defined by how fast they run, or how handsome their face is on a billboard. A hero is defined by what they are willing to endure for others.

 

Feeling a renewed sense of purpose, Izuku turned away from the glass and continued his walk home. His route took him under a dark, concrete overpass. The tunnel was cool, shaded from the late afternoon sun.

 

Izuku let out a breath, enjoying the sudden drop in temperature. He lifted his head, preparing to practice his "heroic smile" in the gloom, trying to figure out how to make his tusks look less intimidating.

 

Suddenly, his whiskers went rigid.

 

Every single stiff bristle above his upper lip snapped straight out. The microscopic nerve endings at the base of his vibrissae screamed a warning into his brain.

 

The air pressure behind him had shifted. It wasn't a wind current. It was a mass. Something large, wet, and incredibly dense was emerging from the manhole cover directly behind him. He didn't hear it—the creature moved with an eerie silence—but to his mutant senses, it was as loud as a siren.

 

The smell of sewage, rotten eggs, and stagnant water flooded his nostrils.

 

"Well, well, well," a wet, gurgling voice echoed through the tunnel. "A medium-sized meat-suit... No, wait. Look at the size of this kid. An extra-large meat-suit! Oh, this is perfect. With a body this big, I can hide for weeks!"

 

Izuku spun around, his thick legs moving with surprising rotational speed.

 

Rising out of the sewer grate was a towering mountain of dark green, viscous sludge. Two massive, manic eyes swirled in the liquid, staring hungrily at Izuku’s massive frame. It was a villain made entirely of fluid.

 

Izuku’s heart hammered against his ribs, but this time, it wasn't out of social anxiety. It was a primal, adrenaline-fueled surge.

 

The Sludge Villain lunged, sending a massive wave of toxic liquid shooting forward like a tidal wave, aiming directly for Izuku’s face, seeking to enter his mouth and nose to hijack his body.

 

Most people would have frozen. Most people would have tried to run, only to be swallowed instantly.

 

Izuku didn't run. He knew his body wasn't built for a sprint.

 

Instead, the Walrus did what he was evolved to do.

 

He planted his feet wide, dropping his center of gravity low to the concrete. He took a massive, deep breath—expanding his lungs to a capacity capable of surviving for forty-five minutes underwater—and clamped his mouth shut. He tucked his chin down, bringing his thick, fourteen-inch ivory tusks forward like a barricade, and brought his heavily padded arms up to protect his eyes.

 

Crash!

 

The sludge slammed into Izuku like a freight train.

 

The impact was tremendous. The villain weighed hundreds of pounds in liquid mass. The kinetic force should have swept Izuku off his feet and slammed him against the concrete wall.

 

But Izuku Midoriya was an immovable object.

 

The thick layers of dense blubber across his back and chest rippled, instantly absorbing the kinetic shock of the impact. The force dispersed harmlessly across his massive torso. His custom-made shoes squeaked against the concrete, sliding backward exactly two inches, and then stopped dead.

 

"What?!" the Sludge Villain gurgled, its liquid body wrapping around Izuku, trying to find a weak point. "You're heavy! Really heavy! But it doesn't matter! Open your mouth, kid! I just need to get inside!"

 

The sludge slithered up Izuku’s neck, pressing against his face, trying to force its way into his nose and mouth. The pressure was immense. The villain pushed inward, trying to crush Izuku’s windpipe.

 

But a walrus's throat and nasal passages are surrounded by incredibly dense rings of muscle, designed to seal completely shut under the crushing pressure of the deep ocean. Izuku’s throat muscles locked. His nose sealed. He didn't need to breathe; he had enough oxygen in his blood and muscles to last him the better part of an hour.

 

Izuku opened his eyes beneath the muck. The villain was trying to suffocate him, but Izuku felt no panic. He was in his element. He was under pressure.

 

He's fluid, Izuku’s analytical mind raced, even as he was engulfed in darkness. Physical punches won't work. But he has eyes. Eyes are solid.

 

Izuku reached up with both of his massive, thick-fingered hands. He didn't try to punch the sludge. He didn't try to pull it off. He dug his fingers into the viscous mass, using his highly sensitive whiskers to locate the exact position of the villain’s physical eyeballs swimming within the muck.

 

Gotcha.

 

Izuku gripped the sludge surrounding the eyes and squeezed with all the grip strength a three-hundred-pound mutant could muster.

 

"AGGGHHHH!" the Sludge Villain shrieked, the fluid around Izuku violently shuddering. "Let go! You're crushing them! Let go of my eyes!"

 

Izuku didn't let go. He planted his feet and yanked hard, tearing the physical eyes away from his face. The villain recoiled in agony, the sludge peeling away from Izuku’s body.

 

Izuku gasped for air, his tusks gleaming with toxic slime. He glared at the swirling mass of villainy, his usually timid emerald eyes burning with a fierce, predatory light.

 

Before the villain could recover and strike again, a massive shockwave rattled the very foundations of the tunnel.

 

The manhole cover clattered away. A towering figure stepped out of the shadows, radiating a golden, overwhelming aura of power.

 

"FEAR NOT, YOUNG MAN!" a booming voice echoed, a voice Izuku had heard a thousand times on his computer screen. "FOR I AM HERE!"

 

All Might stood at the entrance of the tunnel, his blue eyes locked onto the Sludge Villain, his legendary smile in place.

 

Izuku’s jaw dropped, his tusks clicking together. All... All Might?!

 

"A hero?!" the Sludge Villain screamed in terror, whipping a tendril of sludge toward the Number One Hero.

 

All Might didn't even flinch. He pulled back his right arm. The muscles bulged, tearing the fabric of his white t-shirt. "TEXAS..."

 

He threw the punch.

 

"...SMASH!"

 

The air pressure inside the tunnel violently inverted. A localized hurricane exploded from All Might’s fist. The sheer wind pressure hit the Sludge Villain, ripping his liquid body apart, scattering him into a thousand harmless droplets across the tunnel walls.

 

The wind hit Izuku, too. A normal person would have been blown backward, tumbling head over heels. Izuku simply widened his stance, his blubber jiggling wildly as it absorbed the aerodynamic shock, his tusks cutting through the gale. He stood his ground, weathering the storm of the Number One Hero with his eyes wide in awe.

 

As the wind died down, All Might stood up straight, holding two empty plastic soda bottles. In a blur of motion, he scooped up the scattered sludge, sealing the villain away.

 

"EXCELLENT WORK STANDING YOUR GROUND, YOUNG MAN!" All Might boomed, turning his massive smile toward Izuku. "AND APOLOGIES FOR GETTING YOU CAUGHT UP IN MY VILLAIN HUNT! ARE YOU UNHARMED?"

 

Izuku couldn't speak. He was staring at the towering god of heroism. He was close enough to see the shading on All Might’s face, to feel the heat radiating from his massive body.

 

"Y-Y-You're... You're All Might!" Izuku finally squeaked, his deep voice cracking into a high pitch that sounded hilarious coming from a boy his size. "Oh my god! M-My notebook! I need an autograph!"

 

Izuku scrambled, picking up his wet, burned notebook from the ground. He flipped it open to a blank, slightly damp page and thrust it toward the hero with trembling hands.

 

"HAHAHA! OF COURSE!" All Might laughed, taking the notebook. He produced a massive marker and scrawled his signature across two entire pages in less than a second.

 

Izuku stared at the signature, his heart soaring. A family heirloom! I'll frame it! No, I'll build a shrine!

 

"WELL, I MUST BE OFF!" All Might declared, patting his pockets to ensure the bottles were secure. "A HERO'S WORK IS NEVER DONE! STAY SAFE, YOUNG MAN!"

 

All Might bent his knees, preparing to leap.

 

Wait.

 

The thought struck Izuku with the force of a physical blow. He's leaving. This is my only chance. I have to ask him. The number one hero in the world. He'll know the truth. He'll tell me if I'm just a useless, heavy freak.

 

"Wait!" Izuku yelled, stepping forward. "I have a question!"

 

"NO TIME FOR QUESTIONS!" All Might laughed, his muscles coiling like springs. "I MUST BRING THIS FELLOW TO THE POLICE!"

 

All Might launched himself into the air. The concrete cracked beneath his boots. He rocketed out of the tunnel and into the sky like a missile.

 

He was fifty feet in the air when he felt a strange, heavy drag on his right leg. It wasn't the wind resistance. It felt like he was dragging an anchor.

 

All Might looked down.

 

His eyes bugged out of his head. Blood sprayed from his mouth in sheer, comical shock.

 

Clinging to his leg, his massive, thick-fingered hands wrapped around All Might’s calf in a death grip, was the three-hundred-and-fifty-pound mutant boy. Izuku’s tusks were pressed flat against All Might’s shin, his blubber flattening against the hero's leg in the extreme wind pressure, his green eyes wide with terror as the ground fell rapidly away beneath them.

 

"H-H-HEY!" All Might shouted over the rushing wind, trying to shake his leg. The boy didn't budge; his grip strength was terrifying. "LET GO! ARE YOU CRAZY?! YOUR FANATICISM GOES TOO FAR!"

 

"IF I LET GO NOW, I'LL FALL AND DIE!" Izuku screamed back, his deep voice tearing through the wind, his whiskers plastered flat against his face.

 

All Might realized the logic in that. He cursed internally, looking around for a place to land. He felt a sharp, stabbing pain in his side. His time limit was rapidly approaching. He had over-exerted himself.

 

He spotted a tall, empty office building nearby. Changing his trajectory, All Might angled toward the roof. They came in hot. All Might touched down, skidding across the gravel roof. Izuku let go, his massive body hitting the roof with a heavy thud, rolling a few times before coming to a stop, groaning in dizziness.

 

"Good grief," All Might gasped, leaning against the railing, clutching his side. "If you wanted to talk, you could have just knocked on the door of my agency. What you did was incredibly dangerous, kid!"

 

Izuku pushed himself up onto his knees. He felt sick. His heart was racing. But he had to ask. He looked up at All Might’s broad, heroic back.

 

"I... I had to know!" Izuku yelled, his voice shaking.

 

All Might paused, looking over his shoulder.

 

Izuku slammed his hands down onto the gravel, bowing his head. The weight of ten years of mockery, of Bakugo’s sneers, of the pitying looks from society, all pushed down on his massive shoulders.

 

"I don't have a flashy Quirk," Izuku confessed, his deep voice cracking with emotion. "I'm slow. I'm heavy. People look at my face and my tusks, and they cross the street. They tell me I look like a monster. They tell me that a hero needs to be fast, and dynamic, and... and beautiful. But I want to save people. I want to stand in the way of danger so others don't have to."

 

Izuku raised his head. Tears were streaming down his cheeks, wetting his thick whiskers.

 

"Even if I'm just a slow, heavy, ugly walrus... Can someone like me... can I become a hero like you?!"

 

The wind howled across the rooftop.

 

All Might stood frozen. He looked at the boy. He saw the sheer mass of him. He saw the ivory tusks, the thick blubber, the undeniably mutant features. Society was cruel to heteromorphs. It was a dark, unspoken truth of the hero industry. Marketability often trumped capability.

 

But as All Might looked into the boy’s tear-filled emerald eyes, he didn't see a monster.

 

He saw the spirit of a true shield. He saw a boy who had looked death in the face in the form of a sludge villain and had firmly, instinctively, planted his feet.

 

Suddenly, a violent cough wracked All Might’s body. Steam poured from his pores.

 

Izuku gasped as the Number One Hero vanished in a cloud of white smoke.

 

"All Might?!" Izuku cried out, trying to wave the smoke away.

 

As the steam cleared, the towering, muscular god of heroism was gone. In his place stood a skeletal, emaciated man with sunken eyes, baggy clothes, and sharp, angular features. He wiped a trail of blood from his chin.

 

Izuku’s jaw hit the roof. "W-W-What?! An imposter?! You deflated!"

 

"I assure you, I am All Might," the skeletal man sighed, sitting down heavily against the railing. He lifted his shirt, revealing a horrifying, jagged, sunken scar that covered the left side of his chest. "A souvenir from a villain attack five years ago. Half my respiratory organs were destroyed. I can only do hero work for about three hours a day now."

 

Izuku stared in absolute horror. The invincible hero, broken.

 

"You ask if you can be a hero with your body," All Might said softly, his blue eyes locking onto Izuku’s. "Society is shallow, kid. The public wants a smiling, pristine savior. They judge books by their covers. But let me tell you a secret."

 

All Might gestured to his own ruined body. "The cover doesn't matter when the fire starts. What matters is the foundation. And down in that tunnel... you had a stronger foundation than most pros I know."

 

Izuku’s breath hitched.

 

"You didn't run," All Might continued, pointing a bony finger at Izuku’s chest. "You planted your feet. You held your ground. A villain tried to break you, and you proved to be unbroken."

 

All Might stood up, his skeletal frame looking fragile, but his aura was as commanding as ever.

 

"It won't be an easy path," All Might said, his voice deadly serious. "You will have to work twice as hard to prove the critics wrong. You will have to turn your weight into your greatest weapon, and your perceived slowness into a trap. But to answer your question..."

 

All Might smiled. It wasn't the blinding, camera-ready smile of his muscle form. It was a genuine, warm, deeply human smile.

 

"...Yes. Someone with a heavy, armored body like yours... You can become a hero."

 

Izuku Midoriya, the three-hundred-and-fifty-pound boy with tusks, collapsed forward, his heavy hands gripping his knees as he sobbed openly on the rooftop. The tears fell like rain.

 

For the first time in his life, someone had looked past the blubber, past the tusks, past the biological shell of the beast, and seen the hero waiting to be unleashed.

 

And in his pocket, All Might’s trousers suddenly felt slightly lighter. He patted his leg, his eyes widening in horror.

 

The plastic bottles containing the Sludge Villain were gone. They must have slipped out when the boy had latched onto his leg in the sky.

 

Somewhere below them, in the heart of the city, a tremendous explosion rocked the streets. Smoke billowed into the sky.

 

The trial of the Tusked Hero was about to begin.

 

The explosion echoed through the concrete canyons of Musutafu like a thunderclap, vibrating through the soles of Izuku Midoriya’s massive, custom-made sneakers.

 

On the rooftop, the wind suddenly felt suffocatingly still. Izuku, still on his knees with tears drying on his thick cheeks, slowly lifted his head. His highly sensitive vibrissae—the thick, stiff whiskers sprouting from his upper lip—twitched violently. They didn't just pick up the sound of the blast; they picked up the sudden, localized spike in barometric pressure. They tasted the acrid tang of burning ozone and vaporized concrete drifting up from the streets below.

 

"An explosion?" All Might muttered, his skeletal frame stiffening. He gripped the railing of the roof, his sunken blue eyes scanning the skyline. A thick plume of black smoke was already beginning to spiral into the late afternoon sky, just a few blocks away.

 

Izuku’s heart sank into his heavy stomach. He looked at All Might, then looked down at the hero’s baggy cargo pants.

 

The pockets were flat.

 

"All Might," Izuku rumbled, his deep, resonant voice trembling with a sudden, icy dread. "The bottles. Where are the bottles?"

 

All Might’s hands frantically patted his pockets. His eyes widened in absolute horror. "No... It can't be. When we were in the air... when you grabbed my leg... the sudden drag must have dislodged them."

 

The realization hit Izuku with the force of a physical blow. The Sludge Villain—the terrifying, suffocating mass of liquid death that had nearly crushed him in the tunnel—was free. And it was free because Izuku, in his desperation to ask a question about his own self-worth, had recklessly grabbed the Number One Hero out of the sky.

 

I did this, Izuku thought, his massive chest heaving. Because I was selfish. Because I couldn't accept my own reality without validation.

 

"I have to go," All Might rasped, pushing himself away from the railing. He took a step forward, but his emaciated body betrayed him. A violent cough tore from his throat, speckling the concrete with blood. He fell to one knee, clutching the horrific, sunken scar on his left side. His time limit wasn't just up; his body was actively failing him.

 

"All Might!" Izuku cried out, lumbering forward to help the man up.

 

"Don't!" All Might gasped, holding up a trembling hand. "I... I can't move fast like this. Go down the stairs. Get to safety, young man. Let the other Pros handle it."

 

But Izuku couldn't just walk away. His body moved before his mind could fully process the terror. He turned and sprinted toward the rooftop access door.

 

To say Izuku 'sprinted' was a generous term. At three hundred and fifty pounds, with a skeletal structure denser than concrete and layers of thick blubber designed for deep-sea insulation, Izuku was not built for speed. His run was a heavy, thundering lumber. Each footstep shook the stairwell as he descended the six flights of stairs, his breath rushing in and out of his lungs in deep, oceanic gasps.

 

He burst out of the building and onto the street. The smoke was thicker here, blocking out the setting sun. The smell of burning buildings and the sound of screaming civilians guided him.

 

He pushed through the fleeing crowd. People naturally parted for him. To them, the sight of a towering, six-foot-two teenager with fourteen-inch ivory tusks charging down the sidewalk was almost as terrifying as the villain attack itself.

 

Izuku rounded the corner into the Tatooin Shopping District and froze.

 

It was a warzone.

 

Fires raged on both sides of the street, licking the sides of the commercial buildings. The heat was immense, baking the pavement. For a normal person, the temperature would have been unbearable. For Izuku, it triggered his body's extreme thermal regulation. The thick layer of blubber beneath his skin acted as a perfect insulator, keeping his core temperature stable while the sweat instantly cooled his tough, rubbery epidermis.

 

In the center of the fiery destruction stood the Sludge Villain.

 

It had grown even larger than before, feeding off the chaos and whatever moisture it could pull from the broken water mains. Its gelatinous, dark green body writhed and bubbled, laughing maniacally as it lashed out with thick tendrils of toxic muck.

 

"Stay back!" the Pro Hero Death Arms shouted, holding his arms out to keep the gathering crowd of onlookers at bay. "It's too dangerous!"

 

Izuku moved to the front of the crowd, towering over the adults around him. His green eyes scanned the battlefield, his analytical mind instantly breaking down the situation despite the paralyzing guilt gnawing at his chest.

 

Why aren't the Pros doing anything? he thought, his whiskers twitching as they mapped out the heroes' positions.

 

Death Arms was a close-combat brawler. Izuku watched as the hero charged forward, throwing a massive punch at the sludge. The fist sank harmlessly into the fluid, and the villain simply swatted Death Arms away with a liquid backhand. Physical attacks are useless without an area-of-effect.

 

Kamui Woods stood to the side, his wooden limbs trembling. Wood is flammable. The fires are too close. If he tries to bind the villain, he'll catch fire immediately.

 

Mt. Lady, the giantess who had debuted earlier that day, was forced to stand at the edge of the district. "I need at least a two-lane road to maneuver!" she complained, shrinking back down to avoid crushing the surrounding buildings. She's too big. She lacks precision.

 

Backdraft, the water-based rescue hero, was entirely focused on keeping the fires from spreading to the residential zones.

 

They're in a stalemate, Izuku realized, his heart hammering against his ribs. They're waiting for someone with a suitable Quirk. Someone who can blow the villain away or freeze him.

 

"Don't come near me!" a voice shrieked from the center of the sludge.

 

Izuku’s breath caught in his throat.

 

Amidst the swirling, bubbling mass of green liquid, a figure was trapped. The villain wasn't just destroying the street; it was using a hostage as a biological battery and a meat shield.

 

Izuku focused on the center of the sludge. He saw a flash of ash-blonde hair. He saw fierce, terrified crimson eyes glaring out from the suffocating muck. He saw a hand thrust out of the liquid, palm sparking violently, unleashing a series of uncontrolled explosions that fueled the surrounding fires.

 

Kacchan.

 

Katsuki Bakugo was suffocating. The very Quirk that made him the pride of Aldera Junior High, the explosive power that he boasted would make him the Number One Hero, was completely useless. The explosions only scattered the sludge momentarily before it reformed, while the villain fed on the raw kinetic energy to grow larger.

 

"Such a powerful Quirk!" the Sludge Villain gurgled, its liquid face twisting into a grotesque grin. "With this kid's body, I'll be unstoppable! Even All Might won't be able to touch me!"

 

Izuku’s tusks clicked together. His massive hands balled into fists, his thick fingernails digging into his calloused palms.

 

This is my fault, Izuku thought, his vision blurring with tears. Kacchan is going to die because I was weak. Because I needed someone to tell me my heavy, ugly body wasn't useless.

 

"Isn't there a hero who can stop this?!" a woman in the crowd cried out.

 

"We just have to wait!" another Pro said, gritting his teeth. "Hold the line! Someone with the right Quirk will show up!"

 

Wait.

 

The word echoed in Izuku’s mind. They were waiting. They were watching a fourteen-year-old boy drown in toxic waste, and they were calculating the odds. They were waiting for a savior with the right aesthetic, the right elemental counter, the right public image.

 

Izuku looked at Bakugo’s eyes. The arrogance, the explosive pride, the relentless fury—it was all gone. Replaced by the primal, universal terror of a human being realizing they were taking their last breath. Bakugo’s eyes pleaded for help.

 

Izuku Midoriya didn't have a flashy Quirk. He didn't have explosions, or ice, or anti-gravity. He was a boy trapped in the body of a deep-sea leviathan, heavy, sluggish on land, and completely devoid of ranged attacks.

 

But he had an immovable object. He had a body built to withstand crushing pressure. And he had a heart that refused to wait.

 

Before his brain could formulate a plan, before his anxiety could paralyze him, Izuku’s massive tree-trunk legs propelled him forward.

 

"Hey! Kid! Stop!" Death Arms roared, reaching out to grab Izuku's shoulder.

 

But grabbing Izuku was like trying to stop a moving boulder. Death Arms’ hand slapped against Izuku’s incredibly thick shoulder muscle, and the Pro Hero was actually spun around by the sheer momentum of the boy's mass.

 

Izuku burst through the police barricade, his custom sneakers pounding against the burning asphalt.

 

"You?!" the Sludge Villain hissed, its swirling eyes locking onto the massive, tusked teenager barreling toward him. "The heavy freak from the tunnel! You want to die that badly?!"

 

Izuku didn't answer. He couldn't. His throat was locked tight, his body instinctively preparing for extreme physical trauma.

 

He remembered his notebooks. He remembered his obsessive analysis of heroes like Gang Orca and Fat Gum. When you lack speed, you use momentum. When you lack ranged attacks, you become the projectile.

 

Izuku reached his right arm back and hurled his yellow school backpack with all his might. The heavy bag flew through the air, the brass zippers glinting in the firelight. It struck the Sludge Villain squarely in the eye.

 

"Gah!" the villain recoiled, the liquid shifting just enough to expose Bakugo’s mouth.

 

Bakugo gasped for air, coughing up foul-tasting sludge. His crimson eyes widened in absolute disbelief as he saw who was charging toward him.

 

"Deku?!" Bakugo choked out. "What the hell are you doing?! Get away from me, you fat freak!"

 

"My legs..." Izuku yelled, tears streaming down his face as his deep voice boomed over the crackling fires. "...They moved on their own!"

 

Izuku was five feet away. The Sludge Villain recovered, its eyes narrowing in pure, murderous rage. It formed a massive, spiked tendril of compressed liquid, winding it back like a pitcher preparing to throw a fastball.

 

"I'll crush you!" the villain roared.

 

Izuku didn't dodge. He couldn't have dodged even if he tried.

 

Instead, he leaned forward, dropping his center of gravity. He tucked his chin into his chest, exposing the massive, impenetrable hump of muscle and blubber on his upper back and shoulders. He brought his arms up, guarding his ears.

 

CRACK!

 

The sludge tendril struck Izuku squarely in the chest with the force of a hydraulic press.

 

The impact echoed across the shopping district. The crowd gasped. Death Arms winced, expecting to see the teenager's ribs cave in, expecting to see him swatted through the window of a nearby storefront.

 

But Izuku didn't fly backwards. He didn't even stumble.

 

His blubber rippled, absorbing the catastrophic kinetic force in a fraction of a second. The liquid shattered against his tough, rubbery skin, splashing harmlessly onto the asphalt. Izuku’s immense weight anchored him to the ground. He was a biological fortress.

 

"What?!" the Sludge Villain shrieked, completely baffled. "How are you not broken?!"

 

Izuku pushed forward, closing the distance. He didn't stop until his massive chest collided with the villain's main body. He plunged his arms directly into the suffocating green muck.

 

The cold, toxic slime immediately wrapped around Izuku’s arms, sliding up his neck, trying to find its way into his nose and mouth, just as it had in the tunnel. But Izuku’s nasal passages were sealed tight, his throat locked down by muscles designed to withstand the crushing abyss of the arctic ocean.

 

He blindly dug his thick, padded fingers into the sludge, searching for Bakugo.

 

"Get off me!" Bakugo yelled, his pride overriding his survival instinct. He sparked his right hand, unleashing a point-blank explosion directly against Izuku’s chest.

 

BOOM!

 

The flash blinded the onlookers. Smoke billowed out from the center of the conflict.

 

"The idiot kid just blew up his rescuer!" Kamui Woods yelled in horror.

 

The smoke cleared. Izuku was still there.

 

The front of his Aldera Junior High uniform was completely incinerated, revealing his incredibly broad, barrel-like torso. His skin was slightly blackened by soot, but there were no burns. The explosive force and heat had been instantly diffused by the deep-sea insulation of his blubber. He didn't even blink.

 

"Kacchan," Izuku rumbled, his voice incredibly deep and calm despite the chaos around him. "Stop fighting me. Let me help you."

 

Bakugo stared at Izuku’s unburned chest, completely paralyzed by a mixture of shock and incomprehensible humiliation. His explosions, his ultimate weapon, meant absolutely nothing to the boy he had mocked his entire life.

 

"Fine!" the Sludge Villain roared, realizing physical strikes wouldn't work on the leviathan. "If I can't crush you, I'll drown you both!"

 

The sludge surged, rising up like a tidal wave and crashing down over both teenagers. It completely engulfed them, forming a massive, swirling dome of green liquid.

 

From the outside, it looked like the villain had won. The Pro Heroes cursed, preparing to charge in, fearing the worst.

 

Inside the dome, Izuku was plunged into darkness. The pressure was immense. The villain was trying to squeeze them, compacting the liquid to crush their bones. Beside him, Izuku felt Bakugo’s ribs groaning under the strain. Bakugo was losing consciousness, his struggles growing weak.

 

Izuku couldn't punch the liquid away. He couldn't blast it.

 

But I am a walrus, Izuku thought, a primal, ancient instinct overriding his human panic.

 

He didn't just have blubber. He had weapons.

 

Izuku opened his mouth, feeling the thick, foul liquid rush in, but he kept his throat sealed. He engaged his neck muscles—muscles thick enough to pull his three-hundred-and-fifty-pound body across solid ice.

 

With a brutal, violent twist of his head, Izuku slashed upward with his fourteen-inch ivory tusks.

 

The tusks didn't just slice through the liquid; the sheer physical displacement created an underwater shockwave. Izuku violently thrashed his head side-to-side, his tusks acting like massive, churning oars, tearing the villain's fluid structure apart from the inside.

 

"AGHHH!" the Sludge Villain’s voice bubbled in agony. The tusks were tearing through the denser, vital parts of its liquid anatomy.

 

Izuku’s vibrissae twitched. Through the shifting liquid pressure, his whiskers located the villain's eyes—the only solid mass in the creature's body.

 

Izuku didn't hesitate. He lunged forward, swinging his massive head. He hooked his right tusk directly underneath the villain's left eye.

 

"NO!" the villain screamed.

 

Izuku planted his feet, anchored his immense weight, and violently threw his head back, using his tusk like a grappling hook.

 

The dome of sludge exploded outward.

 

The crowd screamed as the villain was physically ripped apart by the sheer mechanical force of Izuku’s neck toss. The green liquid splattered across the burning buildings, losing its cohesion.

 

Izuku stood in the center of the cratered street, breathing heavily. His uniform was in tatters. His tusks were coated in green slime. In his massive right arm, he held Katsuki Bakugo, dragging the gasping, coughing boy out of the muck.

 

Bakugo fell to his hands and knees, vomiting up sewage and gasping for the sweet, smoky air.

 

Izuku stood over him, an immovable wall of muscle and blubber, his eyes scanning the scattered remains of the villain.

 

"You..." Bakugo coughed, looking up at Izuku’s massive silhouette against the firelight. "...Why?"

 

Izuku looked down at the boy who had told him to jump off a roof just hours earlier. He saw the bully, but more than that, he saw a kid who had been scared.

 

"I couldn't just stand and watch you die, Kacchan," Izuku said softly, his deep voice carrying a gentle sincerity that felt completely at odds with his beastly appearance. "Your eyes... they looked like they were asking for help."

 

Bakugo’s eyes widened, a complex storm of humiliation, rage, and unspoken gratitude swirling in his crimson irises. He gritted his teeth, looking away.

 

But the fight wasn't over.

 

The scattered sludge began to pool together rapidly. The villain was reforming, and this time, it was driven by pure, unadulterated hatred.

 

"I'LL KILL YOU!" the Sludge Villain shrieked, gathering every ounce of its mass into a towering, wave-like structure that loomed twenty feet above them. It was condensing its liquid, making it dense enough to shatter concrete. "I'LL FLATTEN YOU BOTH INTO PASTE!"

 

Izuku looked up at the towering wave of death. He calculated the mass. He calculated the velocity.

 

My blubber can take a lot, Izuku realized, his analytical mind cold and clear. But if he drops that much dense mass on me from that height... my spine might snap. And Kacchan won't survive the secondary impact.

 

There was no time to run. There was no time to throw Bakugo clear.

 

Izuku Midoriya made his choice.

 

He didn't scream. He didn't flinch. He turned his back to the towering wave of sludge. He dropped to his knees, straddling Bakugo, and bent forward. He wrapped his massive, thick arms around his head, curling his heavy body into a protective dome over Bakugo.

 

He became a living meat shield. He offered his own unbreakable body to the crushing wave, determined to absorb the entire impact so that Bakugo wouldn't feel a thing.

 

I am a hero, Izuku thought, squeezing his eyes shut. I am the shield.

 

Bakugo looked up from beneath Izuku’s massive chest, his eyes trembling as he watched the boy he called a freak lay down his life for him.

 

The sludge wave crashed down.

 

But the impact never came.

 

A hand—large, powerful, and radiating an immense, burning heat—slapped against Izuku’s shoulder.

 

"I truly am pathetic," a booming, familiar voice echoed over the roar of the flames.

 

Izuku snapped his eyes open. He looked over his shoulder.

 

Standing there, holding back the entire twenty-foot wave of dense sludge with a single, trembling arm, was All Might. The Number One Hero had pushed past his limit, ignoring the blood leaking from his mouth, his muscles bulging with impossible power.

 

"All Might?!" Izuku gasped.

 

"I TOLD YOU WHAT MAKES A CHAMPION," All Might roared, his blue eyes blazing with a fierce, reborn light as he looked down at Izuku. "YET I DID NOT LIVE UP TO MY OWN WORDS! PROS ARE ALWAYS RISKING THEIR LIVES! THAT IS THE TRUE TEST OF A HERO!"

 

All Might pulled his right arm back. The air around them seemed to vacuum inward, drawn to the sheer kinetic potential coiled within his muscles.

 

"DETROIT..."

 

All Might threw the punch.

 

"...SMASH!"

 

The air didn't just move; it shattered. A localized tornado erupted from All Might’s fist. The wind pressure was so catastrophically high that it defied the laws of physics.

 

The shockwave hit the Sludge Villain, completely vaporizing its liquid form, blowing the villain into microscopic droplets that shot high into the atmosphere. The sheer force of the wind extinguished the fires raging on the buildings in a millisecond, blowing the flames out like candles.

 

But the wind hit Izuku and Bakugo, too.

 

The gale-force winds tore through the street, ripping streetlights from their concrete foundations and shattering the remaining windows. Bakugo would have been blown halfway down the block if he wasn't anchored beneath Izuku.

 

Izuku faced the wind. His three-hundred-and-fifty-pound body, anchored by his incredibly dense skeletal structure, dug into the asphalt. His blubber absorbed the aerodynamic shock, his skin rippling violently in the hurricane. He wrapped his arms tighter around Bakugo, holding his ground against the Number One Hero's ultimate attack.

 

He didn't budge an inch.

 

Slowly, the wind died down. The dust settled.

 

Izuku looked up. The sky above them, previously filled with thick, suffocating smoke, was clear.

 

A single drop of water fell onto Izuku’s thick nose. He blinked.

 

Another drop fell. And then another.

 

The sheer upward pressure of All Might’s punch had altered the local weather patterns, forcing the moisture in the air to condense. It was raining.

 

The crowd of onlookers stared in stunned, absolute silence. Then, a single person clapped. Then another. Within seconds, the Tatooin Shopping District erupted into deafening cheers.

 

All Might stood tall, his fist raised to the sky, steam pouring off his overheated body. But out of the corner of his eye, he looked down at the massive, tusked teenager who had held his ground when everyone else had frozen.

 

He really is an immovable object, All Might thought, a smile tugging at his lips. What a terrifying, magnificent Quirk.

 

 

 

The aftermath of the battle was chaotic, loud, and incredibly humiliating for Izuku.

 

While Bakugo was surrounded by paramedics and Pro Heroes praising his resilience and his flashy Quirk, Izuku was pulled aside by Death Arms and Kamui Woods.

 

"Are you out of your mind, kid?!" Death Arms yelled, poking Izuku in his massive, rubbery chest. It was like poking a tractor tire. "You don't just charge into a hostage situation! You have no combat training! You could have gotten yourself killed, or worse, gotten the hostage killed!"

 

"Your mass is impressive," Kamui Woods added sternly, crossing his wooden arms. "But a hero needs to assess the situation. You blindly threw yourself at a villain. You were reckless. Leave the heroism to the professionals next time."

 

Izuku stood there, his shoulders hunched, his chin tucked down so his tusks rested against his chest. He didn't argue. He didn't defend himself. He just nodded, his thick fingers fidgeting with the torn hem of his uniform.

 

They're right, Izuku thought, his deep voice trapped in his throat. I didn't have a plan. I just... reacted. I'm just a big, dumb brute.

 

He looked over at Bakugo. The blonde teenager was glaring at the Pros who were praising him, his face twisted in a scowl of pure frustration. He caught Izuku looking and immediately snapped his head away, his pride refusing to acknowledge what had happened in that sludge dome.

 

Eventually, the police took Izuku's statement and released him. The sky had darkened, the streetlights flickering on as he began the long, heavy walk home.

 

His body ached. Not from the villain's strikes, but from the adrenaline crash. Walking on land was always tiring, but after a fight, his massive muscles felt like lead. He walked with his head down, his whiskers drooping, the weight of the Pro Heroes' scolding settling heavily over him.

 

"Hey! Deku!"

 

Izuku stopped. The voice was unmistakable. He turned his massive body around to see Bakugo marching down the sidewalk toward him, breathing heavily.

 

"Kacchan?" Izuku asked softly.

 

Bakugo stopped a few feet away. He looked up at Izuku, his crimson eyes burning with a complex, furious energy. His hands were balled into fists at his sides.

 

"Listen to me, you fat freak," Bakugo growled, his voice tight. "I didn't ask for your help. I didn't need your help! I was fine! I had him right where I wanted him! You didn't save me, understand?! You just got in the way!"

 

Izuku blinked, his deep green eyes unreadable.

 

"I owe you nothing!" Bakugo yelled, pointing a finger at Izuku's chest. "Don't you ever look down on me again! I'm going to be the Number One Hero, and you're just a... a useless extra!"

 

With that, Bakugo spun on his heel and stomped away, his posture rigid and furious.

 

Izuku watched him go. He didn't feel angry. He knew Bakugo's pride was his armor, just as Izuku's blubber was his. Bakugo couldn't accept being saved by the person he viewed as the lowest rung of the social ladder.

 

Izuku let out a deep, rumbling sigh and turned to continue his walk.

 

"I AM HERE!"

 

Izuku yelped, his massive body instinctively adopting a grappling stance as a towering figure suddenly dashed out from an alleyway, striking a heroic pose in front of him.

 

"A-All Might?!" Izuku gasped, his tusks clicking together in surprise. "What are you doing here? How did you get away from the reporters?"

 

"HAHAHA! STANDING FOR INTERVIEWS IS A BREEZE FOR..." All Might began to laugh, but his body violently rejected the transformation.

 

POOF.

 

Steam exploded outward, and All Might shrank down into his skeletal, blood-spitting form, coughing violently against the brick wall.

 

"All Might!" Izuku cried, stepping forward to catch him, his massive hands hovering nervously, afraid of crushing the frail man.

 

"I'm fine, I'm fine," All Might wheezed, wiping his mouth. He leaned against the wall, taking a deep breath to steady himself. He looked up at the towering, tusked boy.

 

"I came to find you, young Midoriya," All Might said, his voice dropping its booming bravado, becoming earnest and quiet. "I came to apologize, and to correct a mistake."

 

Izuku blinked, his whiskers twitching. "A mistake?"

 

"The Pro Heroes scolded you back there," All Might said, his blue eyes narrowing slightly in frustration. "They called you reckless. They told you to leave it to the professionals. They were wrong."

 

Izuku’s breath hitched.

 

"Of all the people there today," All Might continued, stepping closer to Izuku. "The police, the bystanders, the Pro Heroes with their flashy Quirks... out of all of them, the only one who acted like a true hero was the boy who thought he was a monster."

 

Tears immediately welled in Izuku’s eyes, thick and fast. He tried to wipe them away with his heavy forearms, but they kept falling.

 

"You didn't just charge in blindly," All Might said, his eyes scanning Izuku’s massive frame. "I watched you. You analyzed the situation. You used your bag to create an opening. You used your incredible mass to absorb a blow that would have killed a lesser man. You used your tusks to shatter the villain's structural integrity. You turned your own body into an impenetrable shield to protect a boy who hates you."

 

All Might placed his bony hand on Izuku’s thick, rubbery arm.

 

"A Quirk is just a tool," All Might said softly. "But heroism is an instinct. It's the willingness to put your body on the line. You have a body built for absolute defense, Midoriya. You are an immovable object. And today, you proved that your heart is just as unbreakable as your skin."

 

Izuku couldn't hold it back anymore. He fell to his knees, his massive frame shaking with sobs. He had waited ten years to hear those words. He had endured a decade of mockery, of being called ugly, fat, slow, and useless. And here, the greatest hero in history was telling him he was right all along.

 

"You told me you want to go to U.A. High School," All Might said, looking down at the crying boy.

 

Izuku nodded furiously, his tusks scraping against the pavement.

 

"U.A.'s entrance exam is notoriously difficult," All Might warned him. "It favors flashy, destructive Quirks. It favors speed. Your body is incredibly durable, but you lack stamina on land, and your combat technique is unrefined. You rely purely on your weight."

 

All Might smiled, a fierce, determined grin.

 

"I cannot give you my Quirk, young Midoriya," All Might said, his voice ringing with absolute certainty. "My power is a unique torch, passed down through generations. And quite frankly, your body is a fortress that does not need it. But I can give you my knowledge. I can give you my time."

 

Izuku slowly looked up, his green eyes wide with disbelief.

 

"Ten months," All Might said, holding up a finger. "We have ten months until the U.A. Entrance Exam. If you are willing to bleed, to sweat, and to push that massive body of yours past every biological limit it has... I will personally train you."

 

All Might extended his hand.

 

"I will help you forge that blubber into armor," All Might promised. "I will teach you how to grapple, how to throw, and how to use your weight to crush any obstacle in your path. I will help you become the greatest defensive hero this world has ever seen."

 

Izuku stared at the skeletal hand extended toward him. He thought of Bakugo’s sneers. He thought of the Pro Heroes’ scolding. He thought of the Sludge Villain shattering against his chest.

 

Izuku reached out with his massive, padded hand, gently but firmly grasping All Might’s hand.

 

"I'll do it," Izuku rumbled, his deep voice steady, carrying the weight of the ocean and the heat of a burning fire. "I'll do whatever it takes."

 

All Might smiled. "Then rest up tonight, young Odobenus. Tomorrow, the real hell begins."

 

Ten months.

 

That was all the time Izuku Midoriya had to bridge the gap between a heavily mocked, sluggish teenager and a viable candidate for the most prestigious hero academy in the country.

 

Ten months of agonizing, bone-deep, lung-burning hell.

 

All Might had kept his promise. He hadn't given Izuku a Quirk, but he had given him a blueprint. They had spent the first week at Dagobah Municipal Beach Park, a coastline completely buried under mountains of illegal dumping. All Might hadn't asked Izuku to punch the trash. He hadn't asked him to run on the sand.

 

"Your body is a locomotive, young Odobenus!" All Might had boomed, standing in his muscle form atop a rusted refrigerator. "You do not possess the aerodynamics of a sports car. If you try to run like a track star, you will only exhaust your cooling systems and tear your joints! You must train like what you are: a heavy, unstoppable force!"

 

So, All Might had purchased a custom-made, heavy-duty industrial hauling harness. He strapped it around Izuku’s massive barrel chest. Ropes thicker than a man’s wrist connected the harness to rusted cars, stacks of washing machines, and cast-iron safes.

 

Izuku’s task was to drag them.

 

At first, it was impossible. But slowly, Izuku learned to use his biology. He learned to drop his center of gravity, anchoring his three-hundred-and-fifty-pound frame into the sand. He learned that his thick, tree-trunk legs could generate a terrifying amount of torque if he stepped correctly. He learned to synchronize his breathing, locking his deep-sea neck muscles to stabilize his spine.

 

He didn't lose a single pound over the ten months. In fact, he gained weight. He entered the U.A. Entrance Exam weighing three hundred and seventy pounds. But the composition of his body had shifted. Beneath the incredibly dense, shock-absorbing blubber, his muscles had become thick cords of raw, hauling power. His core strength was astronomical. He spent hours practicing sumo-style harite (open palm strikes) against a padded concrete pillar until the pillar cracked. He practiced grappling, learning to use his immense weight and low center of gravity to throw objects twice his size.

 

And now, the day had arrived.

 

Izuku stood before the massive, towering glass gates of U.A. High School. The morning air was crisp, but Izuku was already running warm. He wore a specially tailored track suit provided by a support company All Might had contacted. It was a deep, ocean blue, made of a highly breathable, reinforced micro-mesh designed to wick sweat and passively vent his body heat. Around his waist was a heavy utility belt containing specialized hyper-cooling gel packs, just in case he approached thermal overload.

 

His fourteen-inch ivory tusks had been carefully filed the night before, blunted at the tips to avoid lethally impaling a fellow student by accident, though they remained formidable, unbreakable weapons of solid dentin. His thick vibrissae twitched in the morning breeze, picking up the heartbeats, the nervous shuffling, and the ambient temperature of the hundreds of teenagers flocking toward the entrance.

 

"Okay," Izuku rumbled to himself, his deep, oceanic voice vibrating in his chest. "Just... just an exam. Just like dragging the trucks at the beach."

 

"Out of my way, Blubber Boy."

 

The harsh, familiar growl made Izuku’s whiskers flatten. He didn't turn around. Katsuki Bakugo walked past him, his hands shoved deep into his pockets, his crimson eyes glaring straight ahead. Bakugo hadn't spoken a single word to Izuku since the Sludge Villain incident ten months ago. The explosive teenager had simply doubled down on his own training, his pride refusing to acknowledge the massive shadow standing behind him.

 

Izuku watched him walk away, letting out a slow breath. He took a heavy step forward.

 

Crunch.

 

His custom, extra-wide sneaker caught the edge of a raised paving stone. Because his legs were so thick, his gait was naturally wider and less agile. Izuku felt his center of gravity pitch forward. He was going to fall. Three hundred and seventy pounds of dense muscle and blubber plummeting toward the pavement was not going to be a simple trip; it was going to crater the walkway and likely injure anyone standing too close.

 

He threw his massive arms out, bracing for the impact.

 

"Oops! Gotcha!"

 

A sudden, strange sensation washed over Izuku. The terrifying pull of gravity vanished. He hung in the air, his tusks mere inches from the concrete, completely weightless. He flailed his thick limbs, looking remarkably like a massive marine mammal swimming through empty air.

 

"Sorry for using my Quirk on you without asking!" a cheerful voice chirped.

 

Izuku rotated his massive torso. A girl with a round face, large brown eyes, and permanent pink blushes on her cheeks was standing beside him, her hands pressed together. She was tiny—barely coming up to Izuku’s chest—but she looked at his intimidating, tusked face without a shred of fear or disgust.

 

"It's bad luck to fall right before the exam, right?" she smiled. "I'm Uraraka Ochaco!"

 

She pressed her fingers together, and the effect canceled.

 

THUD.

 

Izuku hit the ground, but he landed easily on his feet, his massive leg muscles absorbing the drop without a sound. He stood up to his full six-foot-two height, suddenly acutely aware of how imposing he must look. He hunched his broad shoulders inward instinctively.

 

"A-Ah! T-Thank you!" Izuku stammered, his deep, rumbling voice stuttering awkwardly. He bowed, careful not to hit her with his tusks. "I'm Midoriya Izuku. T-Thank you for catching me. I'm... I'm really heavy. That would have hurt."

 

"You don't look heavy, you look super strong!" Uraraka beamed, genuinely impressed. "Your Quirk looks amazing! Are those real tusks?"

 

Izuku blinked. She wasn't staring at him like he was a monster. She was looking at him with the same curiosity she would give to someone with a fire or speed Quirk.

 

"Y-Yeah. It's a mutant type. Walrus," he muttered, rubbing the back of his thick neck.

 

"So cool! Well, let's both do our best, Midoriya-kun!" she waved, jogging off toward the auditorium.

 

Izuku stood there for a moment, his whiskers curling upward into a massive, genuine smile. She talked to me. She didn't call me a freak. I'm going to do my best!

 

 

 

The orientation in the auditorium was a sensory nightmare. Hundreds of teenagers packed into tight rows, the air thick with nervous energy, sweat, and cheap cologne. Izuku was forced to stand in the very back aisle, as he physically could not fit into the standard folding seats. His broad shoulders would have crushed the armrests, and his thighs wouldn't fit under the desks.

 

He didn't mind. Standing in the dark, he listened with rapt attention as the Voice Hero: Present Mic explained the practical exam.

 

"It's a massive cityscape!" Present Mic shouted, posing dynamically on the stage. "You'll be facing off against three types of faux villains! One-pointers, two-pointers, and three-pointers! Destroy them with your Quirks and rack up those points!"

 

Villain bots, Izuku noted, clicking a heavy pen in his thick fingers as he scribbled in a new, unburned notebook. Targeting their visual sensors or mobility treads will be key. My physical strikes are blunt-force. I won't be able to slice through their armor like someone with a blade Quirk. I'll need to rely on crushing force, joints, and sheer mass.

 

"Excuse me! I have a question!"

 

A tall boy with glasses and an incredibly stiff posture stood up, pointing rigidly at the stage. "On the printout, there are four types of villains! If this is a misprint, U.A., the top hero agency in Japan, should be ashamed!"

 

The boy then pivoted violently, pointing his stiff hand directly at the back of the auditorium, singling out the massive silhouette standing in the shadows.

 

"And you! The large one standing in the back! Your heavy, wet breathing is incredibly distracting! If you are here on a sightseeing trip to look at a zoo, then please leave immediately! You are disturbing the focus of those of us who are taking this seriously!"

 

The entire auditorium turned to look at the back aisle.

 

Izuku froze. His deep-sea lungs naturally drew in massive, audible volumes of air, a biological necessity for his size. He felt hundreds of eyes judging his tusks, his bulk, his mutant features.

 

"I... I apologize," Izuku rumbled. His voice, naturally deep and echoing, rolled over the silent auditorium like a distant foghorn. "My respiratory system is adapted for deep-sea oxygen storage. I am not trying to be distracting. I will try to breathe quieter."

 

He bowed respectfully. The boy with glasses blinked, seemingly taken aback by the incredibly polite, articulate response coming from someone who looked like an apex predator. The boy cleared his throat, suddenly looking slightly embarrassed. "I... I see. Forgive my assumption." He sat down.

 

"Right on, Examinee 7111!" Present Mic laughed, diffusing the tension. "The fourth villain type is the Zero Pointer! It's an obstacle! A massive gimmick that will go on a rampage in tight spaces. My advice? Run away from it! It's not worth the risk!"

 

An obstacle, Izuku thought, his whiskers twitching. Like a natural disaster. You don't fight a landslide. You survive it.

 

 

 

"START!"

 

Present Mic’s voice blasted from the massive speakers towering over the gates of Battle Center B.

 

The colossal steel doors groaned open, revealing a sprawling, eerily pristine fake city. For a split second, the hundreds of examinees gathered at the starting line just stood there, waiting for a countdown.

 

"What's the matter?! There are no countdowns in real battles!" Present Mic screamed from the observation tower. "Run! Run! Run!"

 

The crowd exploded. Teenagers surged forward, a tidal wave of flashy Quirks, elemental bursts, and superhuman speed. Explosions, laser blasts, and engine roars filled the air as the agile fighters rocketed into the city to claim their prey.

 

Izuku Midoriya was left behind.

 

It wasn't that he wasn't trying. He pushed off the ground, his custom sneakers gripping the asphalt. But physics is a cruel mistress. Accelerating three hundred and seventy pounds of dense mass from a standstill required an immense amount of energy. His top running speed was, at best, a moderate, heavy jog.

 

By the time Izuku crossed the threshold of the gates, the street ahead was already littered with the smoking wrecks of destroyed One-Pointers. The fast kids had picked the perimeter clean.

 

Don't panic, Izuku told himself, his breath coming in rhythmic, heavy gusts. All Might said speed isn't your game. You don't hunt the stragglers. You go for the heavy clusters. You find the choke points.

 

Izuku stopped jogging. He closed his eyes.

 

He didn't need to see the robots. He needed to feel them. He focused all his attention on his vibrissae. The incredibly stiff, sensitive bristles above his mouth flared outward, acting as a highly advanced bio-sonar and vibration-detection array.

 

The city was loud, but Izuku filtered out the high-pitched screams and the crackle of fire. He listened to the ground.

 

Thump. Thump. Thump.

 

Heavy, rhythmic vibrations echoing from three blocks deep. A massive concentration of mechanical treads and heavy servos.

 

Izuku opened his eyes. He lowered his head, tucked his tusks against his chest, and began a heavy, methodical march toward the center of the city.

 

He turned the corner into a wide intersection. It was chaos. Five examinees were pinned behind a concrete barricade as a swarm of a dozen robots—a mix of One, Two, and Three-Pointers—poured suppressing fire into the street. The robots were firing high-velocity tennis balls and rubber bullets, simulating lethal munitions.

 

"We're pinned down!" a boy with a stretching Quirk yelled. "The Three-Pointers have armor plating! I can't break through it!"

 

Izuku stepped out into the open intersection.

 

"Hey! Giant kid! Get back to cover!" a girl screamed.

 

The robots' optical sensors immediately locked onto the largest target in the area. Three Two-Pointers swiveled their turrets and unleashed a volley of high-speed projectiles directly at Izuku’s broad chest.

 

Thwack! Thwack! Thwack!

 

The rubber bullets and tennis balls struck Izuku with enough force to leave deep bruises on a normal human. But Izuku wasn't normal. The projectiles hit his thick, rubbery skin and literally bounced off. His blubber absorbed the kinetic impact so completely that Izuku didn't even break his stride. It felt like being pelted with raindrops.

 

"Target... unyielding..." one of the Two-Pointers digitized, its processors confused.

 

Izuku didn't dodge. He didn't weave. He walked straight through the hail of simulated gunfire. He raised his massive hands, his palms open, adopting the low, wide stance of a sumo wrestler.

 

"My turn," Izuku rumbled.

 

He lunged. Over a short distance, a walrus is terrifyingly fast. Izuku fired his massive leg muscles, his three-hundred-and-seventy-pound body rocketing forward like a biological cannonball.

 

He collided with the lead Two-Pointer.

 

CRUNCH.

 

The sound of twisting steel echoed through the intersection. Izuku didn't punch the robot. He used an open-palm harite strike, driving his incredibly thick, calloused palm directly into the center of the robot’s chest plate. The sheer kinetic transfer of his body weight behind the strike buckled the robot’s armor inward, shattering its internal motherboard.

 

Without pausing, Izuku reached out with both hands and grabbed the chassis of a One-Pointer to his left. His thick fingers, boasting a grip strength capable of crushing solid bone, dug into the metal. With a primal grunt, he lifted the two-hundred-pound machine completely off the ground and swung it like a massive club, smashing it violently into a Three-Pointer.

 

Both machines exploded in a shower of sparks.

 

The examinees behind the barricade stared in absolute awe.

 

"Six points," Izuku muttered, his whiskers twitching as he scanned the area. He felt his core temperature rising slightly, his body adjusting perfectly to the physical exertion.

 

Another Three-Pointer revved its engine, charging forward to ram him with its treads.

 

Izuku dropped lower. He didn't move away. He braced his wide feet against the asphalt. As the machine collided with him, Izuku caught the front bumper with his hands. The robot’s engine whined, its treads tearing up the street as it tried to push the teenager backward.

 

Izuku was an immovable object. The robot’s treads smoked, unable to gain an inch.

 

With a deep breath, Izuku slid his head downward. He hooked his massive, fourteen-inch ivory tusks directly underneath the robot's front chassis. He engaged his deep-sea neck muscles and heaved upward in a brutal, violent jerk.

 

The Three-Pointer was flipped entirely onto its back, its treads spinning helplessly in the air like a flipped turtle. Izuku casually stepped forward and stomped his massive foot down onto its optical sensor, crushing it into glass powder.

 

"Nine points."

 

Izuku didn't stop. He became a juggernaut. He moved from street to street, ignoring cover completely. He was a walking tank. He let the robots shoot him, unbothered by the impacts, closing the distance to grapple, crush, and flip them. He tore treads off with his bare hands. He suplexed Two-Pointers into the sides of buildings. He used his immense mass to simply walk through the smaller robots, trampling them under his heavy feet.

 

For the first time in his life, Izuku Midoriya was not apologizing for his size. He was weaponizing it.

 

 

 

High above the fake city, in the dimly lit judges' observation room, the faculty of U.A. High School watched the massive bank of monitors in silence.

 

"Remarkable," Nezu, the principal (who was either a mouse, a bear, or a dog), murmured, sipping his tea. He pointed a small paw at a screen focused entirely on Battle Center B. "Look at Examinee 7111. I haven't seen a Heteromorphic fighting style this pure in years."

 

On the screen, Izuku was seen taking a direct, full-speed ram from a Three-Pointer. The machine struck his side, but Izuku merely absorbed the shock, wrapped his arms around the machine in a bear hug, and squeezed until the metal crumpled and the engine died.

 

"He's completely bypassing the agility metric," the heroine Midnight purred, resting her chin on her hand. "He's not dodging at all. He's relying entirely on his structural integrity. It's reckless, but... undeniably effective. His localized durability is off the charts."

 

"It's not just durability," the gruff, tired voice of Shota Aizawa (Eraser Head) chimed in from the corner of the room. He was staring intensely at Izuku’s movements. "Look at his footwork. It's deliberate. He's not just a brute throwing his weight around. He's using leverage. He's engaging his core to maximize kinetic transfer. Someone taught him how to fight like a heavyweight."

 

Standing near the back of the room in his skeletal form, Toshinori Yagi (All Might) beamed with a mixture of intense pride and relief. You're doing it, young Midoriya. You're showing them exactly what it means to be unbreakable.

 

"He has thirty-four villain points," Present Mic noted, tapping a console. "A solid score. But how does he handle... the unexpected?"

 

Nezu’s eyes gleamed. He reached out and pressed a large, ominous red button on his desk. "Let's test their true mettle. Release the obstacles."

 

 

 

Down in Battle Center B, Izuku had just crushed his forty-fifth point by hip-tossing a Two-Pointer into a streetlamp. He was panting heavily, his massive chest heaving. Sweat coated his skin, but his cooling gel packs and the passive venting of his micro-mesh suit were keeping his core temperature entirely manageable. He felt good. He felt powerful.

 

Suddenly, the ground beneath his feet violently pitched upward.

 

Izuku stumbled, catching his balance. His vibrissae went absolutely rigid, vibrating with a frequency that sent a spike of primal terror straight into his brain.

 

Massive barometric drop. Seismic activity. Huge displacement of air.

 

At the end of the main avenue, the buildings literally exploded outward. A shadow fell over the entire street.

 

Rising from the dust and debris was a machine so unfathomably large it dwarfed the surrounding fake skyscrapers. It was the Zero Pointer. A colossal, tread-driven behemoth with glowing red eyes and arms the size of bullet trains.

 

"Holy crap!" a teenager screamed.

 

"It's a monster! Run!"

 

The examinees broke into a full panic. The entire street turned into a stampede as dozens of kids scrambled to get away from the towering mechanical titan. The Zero Pointer raised one of its massive, building-sized fists and brought it down on a nearby structure, shattering the concrete and sending a shockwave of debris and wind tearing down the avenue.

 

Izuku felt the wind ripple against his blubber. His instincts screamed at him to run. Forty-five points is enough. I can't fight that. Nobody can fight that. It's a natural disaster.

 

Izuku turned around. He took two heavy steps away from the robot, joining the retreating crowd.

 

"Ow! My leg!"

 

The voice was faint. It was barely a whisper over the grinding of the Zero Pointer’s treads and the screams of the crowd. But Izuku’s highly adapted ears heard it clearly.

 

He stopped. He turned his massive head.

 

Through the dust, lying near the base of the collapsing building, was Uraraka Ochaco. A massive slab of concrete—a piece of the building the Zero Pointer had just smashed—had fallen across her lower half. She was pinned to the asphalt, desperately trying to push the rubble off, her face contorted in pain.

 

The Zero Pointer was slowly pivoting its treads. It was moving directly toward her. Its massive, tank-like tracks were going to roll right over the rubble, and her, in less than twenty seconds.

 

The other examinees were running right past her. The tall boy with the glasses stopped, looking back, his face stricken with terror, but his legs were paralyzed. He couldn't move toward the danger.

 

Izuku Midoriya didn't think.

 

The anxiety, the calculations, the fear of failure—all of it vanished. He didn't see a giant robot. He didn't see an impossible obstacle. He saw a girl who had smiled at him, a girl who had treated him like a human being, about to be crushed.

 

All Might’s words echoed in his mind.

Heroism is an instinct. It's the willingness to put your body on the line. You are the shield.

 

Izuku dug his custom sneakers into the asphalt. He didn't run away.

 

He charged directly at the Zero Pointer.

 

"What is he doing?!" the glasses-wearing boy screamed, watching the massive, tusked teenager sprint toward certain death.

 

Izuku ignored him. He closed the distance, his thick legs pumping like pistons. He reached Uraraka.

 

"Midoriya-kun?!" she gasped, tears in her eyes. "Run! It's too big! It's going to crush us!"

 

Izuku looked at the concrete slab. It was easily five tons of solid reinforced stone. He looked up. The Zero Pointer's tread was lifting, preparing to crush the very spot they were occupying. There was no time to grab her and pull her out. The slab was too heavy to simply toss aside without ripping her leg off.

 

There was only one option.

 

Izuku didn't try to attack the robot. He didn't try to smash the concrete.

 

He dropped to his knees right beside Uraraka. He leaned forward, forcing his thick, massive torso underneath the lip of the concrete slab. He pressed his chest and shoulders firmly against the asphalt, positioning the apex of his back directly underneath the five-ton weight.

 

"Midoriya, what are you doing?!" Uraraka cried.

 

"I am an immovable object," Izuku rumbled, his deep voice carrying a terrifying, absolute calm.

 

Izuku planted his hands flat against the ground. He braced his thick knees. He tilted his head back, aiming his massive ivory tusks straight up into the underbelly of the concrete slab.

 

"Hold on," Izuku ordered.

 

He engaged every single muscle in his three-hundred-and-seventy-pound body. The thick cords of muscle hidden beneath his blubber flared. His deep-sea spine aligned.

 

With a guttural, oceanic roar that echoed over the battlefield, Izuku pushed up.

 

His tusks pierced the bottom of the concrete, anchoring it. His massive, barrel-like back pressed against the stone.

 

The five-ton slab of concrete groaned, and then, miraculously, it lifted.

 

Izuku didn't throw it. He couldn't. He became a living pillar. The immense weight of the concrete pushed down on him, trying to crush him into the asphalt. Izuku’s blubber compressed, his bones creaked under the astronomical load. His custom suit tore across the shoulders as his muscles bulged to the absolute limit. Blood vessels burst in his eyes, turning his emerald irises a terrifying shade of crimson.

 

But he didn't break. He held it. He was a biological hydraulic press.

 

"Crawl out!" Izuku roared, his voice straining under the titanic weight, spit flying from his lips. "Get out now!"

 

Uraraka, stunned by the sheer, impossible display of raw strength, scrambled backward, dragging her injured leg free from the newly created space.

 

Above them, the sky went dark.

 

The Zero Pointer’s massive foot—a block of steel the size of a house—was coming down. It was going to stomp directly onto the concrete slab Izuku was holding up.

 

Izuku looked up. He saw the steel descending. He couldn't move. If he dropped the slab, he couldn't get out of the way in time.

 

I saved her, Izuku thought, his tusks vibrating as the concrete above him trembled. That's enough. That's what a hero does.

 

He closed his eyes, bracing his body to take the impact of a skyscraper. He prepared to use his blubber to try and survive the impossible.

 

"TIME'S UP!"

 

Present Mic’s voice echoed like the voice of God over the loudspeakers. A deafening siren wailed across the city.

 

The Zero Pointer’s glowing red eyes flickered and died. Its massive foot, mere inches from the concrete slab, hissed as the hydraulics locked in place, freezing the colossal machine instantly.

 

Izuku held the slab for three more seconds, his brain unable to process that the threat had stopped. Then, his muscles gave out.

 

He didn't collapse gracefully. He just... dropped.

 

Izuku fell onto his stomach, letting the concrete slab slam back down onto the asphalt exactly where Uraraka’s leg had been seconds prior. The impact rattled his teeth.

 

He lay there on the ground, completely spent. His massive chest heaved, sucking in oxygen in deep, rattling gasps. Every muscle in his body felt like it was made of liquid fire. His cooling gel packs had completely ruptured, leaking blue fluid all over the street.

 

The street was dead silent. The remaining examinees slowly crept out from behind their cover, staring at the massive, tusked teenager lying in the dust. He hadn't destroyed the Zero Pointer. He hadn't unleashed a flashy explosion.

 

He had simply refused to move. He had held up a collapsing building with his bare back so a girl could live.

 

"Midoriya-kun!"

 

Uraraka limped over to him as fast as she could. She dropped to her knees beside his massive head, her hands hovering nervously over his thick, sweaty shoulders. "Are you okay?! That was incredible! You held it up! You saved me!"

 

Izuku slowly opened his eyes. He saw her crying, but they were tears of relief, not pity. He let out a long, rumbling breath, his whiskers twitching weakly against the asphalt.

 

"You're... you're safe," Izuku mumbled, his deep voice exhausted. He managed a small, tired smile, his tusks scraping against the ground. "That's good."

 

"Very good, indeed!" a new voice called out.

 

The crowd parted as a tiny, elderly woman with a cane shaped like a syringe walked briskly toward them. It was Recovery Girl, the backbone of U.A. High School.

 

She walked up to Izuku. She had to crane her neck to look at his massive head. She tapped his thick bicep with her cane.

 

"Well, aren't you a sturdy one," Recovery Girl praised, looking over his uninjured but exhausted body. "Most kids who try a stunt like that end up with shattered spines. But your bone density and muscle mass are extraordinary. Just extreme muscle fatigue and some localized bruising."

 

She leaned forward and planted a loud kiss on Izuku’s cheek.

 

Izuku felt a sudden, draining wave of lethargy wash over him as his body's natural healing factor was hyper-accelerated. He groaned, burying his face in his arms.

 

"Give him some space, let him breathe!" Recovery Girl ordered the gawking teenagers. She tossed a handful of gummy candies to Uraraka. "Eat these, dear. And let's get that leg looked at."

 

Izuku slowly pushed himself up into a sitting position. He felt like he weighed a thousand pounds. He looked at his hands, thick, calloused, and trembling.

 

He looked around the destroyed street. He saw the ruined robots he had crushed. He looked at the massive concrete slab he had held up.

 

He hadn't been fast. He hadn't been flashy. But he had fought like a hero. He had fought like an Odobenus.

 

I did my best, Izuku thought, looking up at the afternoon sky. All Might... I hope you saw.

 

 

 

In the judges' room, the silence was deafening.

 

The monitors showed the replay of Izuku bracing himself beneath the concrete, his tusks piercing the stone, his body turning into a living, breathing foundation.

 

"He didn't run," Midnight whispered, her usual playful demeanor completely gone, replaced by genuine awe. "He knew he couldn't destroy it. But he knew he could hold it."

 

"A hero's job is not just to defeat the villain," Nezu said softly, sipping his tea, a proud gleam in his dark eyes. "It is to save the innocent. The entrance exam is designed to weed out those who only seek glory through destruction. The true test of the Zero Pointer is whether a student is willing to sacrifice themselves for another."

 

Aizawa uncrossed his arms. He looked at the frozen frame of Izuku’s bloodshot, determined eyes beneath the crushing weight.

 

"He's slow," Aizawa noted, his voice flat but carrying a hint of immense respect. "He's heavily reliant on close-quarters combat. He lacks any ranged capability."

 

Aizawa paused, a rare, microscopic smirk touching the corner of his mouth.

 

"But you'd need a wrecking ball to get past him. He's got the makings of a hell of a shield."

 

In the back of the room, All Might turned away from the monitors. He had to cover his mouth to muffle the wet, rattling cough, but the tears in his sunken blue eyes were impossible to hide.

 

You passed, young Midoriya, All Might thought, his heart swelling with a pride he hadn't felt in years. You didn't just pass. You crushed it.
