What if deku had a blob fish quirk?

 

All men are not created equal. 

Izuku Midoriya learned this fundamental, unyielding truth of the universe at the tender age of four. It was not a lesson taught from a textbook, nor was it handed down through the gentle wisdom of his mother. It was a lesson written into the very biology of humanity, violently highlighted by the dawn of the superhuman society. 

Eighty percent of the global population possessed a "Quirk," a unique genetic mutation that granted them abilities beyond the realm of standard human biology. Some people could breathe fire. Some could manipulate gravity. Some possessed the blinding speed of a lightning bolt or the devastating strength of a localized earthquake. Quirks were celebrated, categorized, and monetized. They were the glittering currency of the modern age, giving rise to a profession that once only existed in the pages of comic books: Pro Heroes.

But there was a dark side to the Quirk lottery. While some drew cards that made them gods, others drew cards that made them monsters, freaks, or simply… punchlines.

Izuku Midoriya, sitting on the edge of his bed on a humid Tuesday morning, was about to discover which card he had drawn.

The day began like any other, but the moment Izuku opened his eyes, something felt profoundly wrong. His body felt heavy, not with the familiar lethargy of a lingering sleep, but with a dense, sinking gravity. He tried to sit up, expecting his core muscles to engage, to pull his torso upright. Instead, a strange, sloshing sensation rippled through his stomach. 

He looked down, his massive, emerald eyes widening in absolute horror. 

His favorite All Might pajamas, the ones that had fit perfectly just the night before, were stretched taut across a stomach that had seemingly expanded overnight. But it wasn't the hard, bloated expansion of a sickness. When Izuku tentatively reached a small, trembling hand down to touch his belly, his fingers sank. 

And sank. And sank.

There was no resistance. His skin felt unnervingly soft, lacking the natural tension of human epidermis. It felt cool to the touch, and beneath it lay a thick, gelatinous mass that yielded completely to his pressure. He pulled his hand away, and the flesh slowly, agonizingly, returned to its original pudgy shape with a faint, wet jiggle.

"Mom!" Izuku shrieked, the sound tearing through the quiet apartment. 

Inko Midoriya rushed into the room, a spatula still gripped tightly in her hand, her face pale with maternal panic. "Izuku? Baby, what’s wrong—" 

She stopped dead in her tracks. The spatula clattered to the wooden floor. 

Her son was sitting on the bed, but he didn't look like her son. His cheeks, usually pleasantly round, had drooped into soft, heavy jowls that seemed to weigh down the corners of his mouth. His arms and legs lacked any definition, replaced by smooth, pale, cylindrical mounds of flesh that seemed to spread out and flatten slightly where they rested against the mattress. He looked, for all intents and purposes, like a child made of partially set pudding.

"Mom," Izuku whimpered, holding up his hands. His fingers were thicker, softer, devoid of knuckles. "I feel weird. I feel… squishy."

Inko rushed forward, her hands hovering frantically over him, terrified that touching him might cause him to burst like a water balloon. When she finally brought herself to touch his shoulder, she gasped. He felt like a dense, heavy jelly. He had no fever, no apparent pain, but his entire physiology had fundamentally shifted in the span of eight hours. 

"Oh, Izuku," she whispered, her eyes welling with tears. "Your Quirk… it’s manifesting."

The waiting room of the Quirk Counseling and Pediatrics clinic was painted a cheerful, sterile yellow, plastered with posters of Pro Heroes demonstrating safe Quirk usage. Izuku sat beside his mother, his feet dangling over the edge of the vinyl chair. Every time he shifted his weight, his bottom seemed to spread out, absorbing the shape of the chair, making it incredibly difficult to slide off. He felt sluggish, heavy, and deeply uncomfortable in his own skin. 

Dr. Tsubasa, a bald, bespectacled man with a thick mustache and an air of clinical detachment, called them into his office. 

Izuku underwent a grueling battery of tests. There were blood draws (which proved immensely difficult, as the needles kept slipping through thick layers of unresisting mucous-tissue before finding a vein), x-rays, reflex tests, and genetic sequencing. Throughout it all, Izuku clung to a singular, desperate hope: Maybe I’m like a slime hero. Maybe I can change shape. Maybe I can stretch like rubber!

Finally, they sat back in the doctor's office, the glowing light of the x-ray board illuminating the room. 

Dr. Tsubasa steepled his fingers, staring at the chart on his desk with a mixture of professional fascination and apathetic pity. "Well, Mrs. Midoriya, the good news is that your son is perfectly healthy. There are no malignant tumors, no degenerative diseases, and no vital organ failure. He is, however, experiencing a severe, full-body mutation."

"A mutation?" Inko asked, wringing her hands nervously. "We have weak telekinesis and fire-breathing in our family. Neither of those are mutant types."

"Quirk genetics are a fickle science," the doctor sighed, clicking a button to display Izuku's x-rays on the monitor. "Sometimes, latent genes skip multiple generations and combine in entirely unprecedented ways. Looking at Izuku’s cellular structure, his Quirk is a highly specific animal mutation."

Izuku’s eyes lit up. "An animal? Like a lion? Or a bear? Mirko has a rabbit mutation and she’s super strong!"

Dr. Tsubasa adjusted his glasses, looking down at the boy. "Not quite, young man. Your cellular makeup, specifically the density of your tissues and the unique lipid-rich gelatin replacing your subcutaneous fat and muscle fibers, is a near-perfect match for a deep-sea creature. Specifically, Psychrolutes marcidus."

Inko blinked. "I’m sorry, what is that?"

"The blobfish," Dr. Tsubasa said bluntly. 

Silence descended upon the room. The hum of the fluorescent lights suddenly felt deafening. 

"A… a fish?" Izuku asked, his voice trembling. "Can I breathe underwater?"

"No," the doctor replied, checking his notes. "You still have lungs, not gills. You see, the blobfish survives in the extreme depths of the ocean, where the hydrostatic pressure is dozens of times higher than at sea level. To survive being crushed, they evolved to lack traditional muscle and bone density. Their bodies are made of a gelatinous mass with a density slightly less than water, allowing them to float above the sea floor without expending energy."

The doctor pointed to the x-ray. "Izuku's bones are still present, but they are highly flexible, almost cartilaginous. His skeletal muscle has been heavily supplemented by this dense, shock-absorbing jelly. On land, without the extreme pressure of the deep ocean to hold his form together, gravity takes over. That is why he appears… pudgy. His body is literally relaxing into a puddle."

"But… but what is his power?" Inko asked, desperation creeping into her voice as she saw the light fading from her son’s eyes. 

"His power is exactly what you see," Dr. Tsubasa said, lacking any bedside manner. "He is essentially a living mass of shock-absorbing gelatin. While this gives him a unique resistance to blunt trauma—I imagine falling off a bicycle wouldn't even bruise him—it offers almost nothing in the way of offensive capability. He lacks the rigid muscle structure required for explosive speed or heavy lifting on land. In terms of Hero work..." The doctor sighed. "I would advise him to look into a more realistic career path. Without a flashy power or superhuman strength, his Quirk is practically useless."

The words struck Izuku like a physical blow. But ironically, a physical blow wouldn't have hurt. This hurt. It tore through his chest, bypassed the thick, gelatinous armor he had just grown, and crushed his heart. 

Useless.

The playground was a battlefield, and Izuku had just been demoted to a civilian. 

A few weeks had passed since the diagnosis. Izuku’s body had settled into its new normal. He was noticeably heavier, carrying a thick, jiggly layer of lipid-jelly over his entire frame. His face was round and soft, his limbs thick and squishy. He moved with a slight waddle, the lack of rigid muscle making him clumsy and slow. 

Katsuki Bakugo, on the other hand, had just ascended to godhood. 

Bakugo’s Quirk had manifested with a literal bang. He could secrete nitroglycerin-like sweat from his palms and ignite it at will. He was loud, explosive, fast, and powerful. He was everything a hero was supposed to be. 

And he was currently standing over a crying boy in the sandbox, small sparks crackling in his palms. 

"You’re in my way, extra," Bakugo sneered, his sharp crimson eyes glinting with a volatile mixture of pride and cruelty. The boy on the ground whimpered, clutching a bruised knee. 

Izuku, despite his slow, waddling gait, stepped between them. He threw his soft, doughy arms out to his sides, his knees trembling. 

"K-Kacchan, stop!" Izuku yelled, his voice cracking. "Can't you see he's crying? If you keep going, I-I'll stop you myself!"

Bakugo stopped, staring at Izuku for a long, quiet moment. Then, a wicked grin spread across his face. 

"You? Stop me?" Bakugo let out a harsh bark of laughter. He stepped forward, bringing his face close to Izuku’s. "You’re a joke, Deku. You look like a melted ice cream cone."

"My name is Izuku," he whispered, though he didn't lower his arms. 

"Your name is Deku. Because you're useless," Bakugo snapped. "What are you gonna do? Squish me to death? Gross me out with your slime?" 

Bakugo lunged forward. He didn't use an explosion—he didn't need to. He just pulled his fist back and punched Izuku squarely in the stomach, putting all his four-year-old weight behind it. 

Izuku squeezed his eyes shut, bracing for the agonizing pain. 

But it never came. 

Bakugo’s fist connected with Izuku's stomach. Instead of striking tight muscle or vital organs, Bakugo's knuckles sank into the thick, dense layer of gelatinous fat. It felt like punching a massive ball of wet dough. The kinetic energy of the punch rippled outward, absorbed instantly by the lipid-rich jelly, dissipating before it could reach Izuku’s ribs or organs. 

Bakugo’s eyes widened in surprise as his fist sank a full two inches into Izuku’s gut, stopping completely as the gelatin naturally condensed to halt his momentum. 

Then, physics took over. The gelatin, having been compressed, rapidly expanded back to its natural shape. 

With a wet, comical boing, Bakugo’s fist was forcefully ejected from Izuku’s stomach. The recoil caught Bakugo off guard, sending him stumbling backward, tripping over his own feet, and landing squarely on his rear in the sand. 

The playground went dead silent. The other kids, who had been watching in awe of Bakugo, stared in stunned disbelief. Bakugo had just been knocked down. By Deku. 

Izuku opened his eyes, looking down at his stomach, then at Bakugo. "I... I didn't feel that."

Bakugo’s face turned violently red. It wasn't the red of a boy who had been hurt; it was the molten red of a boy whose pride had just been shattered in front of an audience. 

"You… you freak!" Bakugo screamed, scrambling to his feet. Small explosions popped rapidly in his palms, smoking with the smell of burnt sugar. "Don't mock me! You're just a gross, ugly blob!"

Bakugo didn't punch this time. He swung his open palm, unleashing a small explosion directly against Izuku’s shoulder. 

BANG!

The heat and concussive force hit Izuku. The heat stung, singing the top layer of his skin and leaving a red, angry welt, but the concussive shockwave—the force that should have knocked Izuku off his feet—was swallowed whole by his shoulder. The flesh jiggled violently, undulating like waves in a bathtub, completely neutralizing the blast. Izuku took a half-step back, crying out from the burn, but he remained standing. 

Bakugo stared at his smoking hand, panting. "Gross. You’re just a gross, bouncy punching bag." He turned his back on Izuku, spitting into the sand. "Come on, guys. Let’s leave Blob-Deku alone. He might get his slime on us."

The other kids laughed nervously, following Bakugo away, leaving Izuku standing in the sandbox. The boy he had protected had already run away while Bakugo was distracted. 

Izuku stood alone. The burn on his shoulder stung terribly—extreme heat, it seemed, was a weakness for his cool, deep-sea biology. But his stomach and the muscles beneath his shoulder felt perfectly fine. 

He looked down at his pudgy hands. The doctor had said his Quirk was useless. Bakugo had called him a punching bag. 

But I didn't fall down, Izuku thought, a strange, quiet spark igniting in his chest. He hit me with everything he had, and I didn't fall down.

The rain lashed against the windowpane of the Midoriya apartment that night, reflecting the somber mood inside. The glow of the computer monitor cast a pale blue light across Izuku's face. 

On the screen, a video played on an endless loop. It was old footage, grainy and chaotic, showing a disaster in a burning city. Out of the smoke and debris, a colossal figure emerged, laughing heartily as he carried a dozen civilians on his back. 

"Fear not, citizens! Hope has arrived. Because I am here!"

All Might. The Symbol of Peace. The greatest Pro Hero in the world. 

Izuku had watched this video a thousand times. Before his Quirk manifested, he had watched it with dreams of shooting lasers or lifting cars, rushing into the fray just like his idol. Now, he watched it through a different lens. 

Inko stood in the doorway, her heart breaking into a million pieces. She saw her son sitting in his chair, rocking slowly back and forth. His body was so different now—so soft, so heavy—but he was still her little boy. 

"Izuku?" she whispered, stepping into the room. 

Izuku didn't turn around. His voice was quiet, hollowed out by a day of cruelty and medical condemnations. "Mom. All Might is so strong. He saves everyone with a smile. No matter what."

He slowly swiveled his chair around. His cheeks were stained with tears, his eyes red and puffy. He pointed a trembling, squishy finger at the screen. 

"Can I... can I be a hero, too?" Izuku asked, his voice breaking. "Even if I don't have a cool power? Even if I'm just... a blob?"

Inko felt a sob tear its way out of her throat. She ran forward, dropping to her knees and throwing her arms around him. She pulled him tightly against her chest, her fingers sinking into his soft back. 

"I'm sorry, Izuku!" she wailed, her tears soaking his shirt. "I'm so sorry! I'm sorry!"

It was the response of a mother mourning her child's dream. It was an apology for his genetics, an apology for the cruel world he would have to face, an apology for the fact that she could not give him the one thing he wanted more than anything else. 

But Izuku didn't hug her back. 

He sat there, perfectly still, his eyes fixed on the computer screen over her shoulder. All Might's laugh filled the small room, a booming sound of defiance in the face of despair. 

No, Izuku thought, a profound sense of clarity piercing through his sorrow. No, Mom. Don't apologize. That's not what I needed you to say.

He didn't need pity. He didn't need an apology. He needed a way forward.

Slowly, gently, Izuku placed his heavy hands on his mother's shoulders and pushed her back. Inko looked at him, startled by the sudden, quiet intensity in his emerald eyes. 

"I'm going to be a hero, Mom," Izuku said softly, but with a conviction that chilled the room. "The doctor said my Quirk is useless for combat. Kacchan said I'm just a punching bag." 

Izuku reached over to his desk. He grabbed a blank notebook, one Inko had bought him for school. He picked up a pen. 

"If I don't have a weapon, I have to be the shield," Izuku said, opening the notebook to the first page. At the top, in clumsy, childish handwriting, he wrote: Hero Analysis for the Future: Volume 1. "If I can't be fast, I have to be immovable. If I can't hit hard... I have to make sure nobody else gets hurt."

He looked back at his mother, offering a small, wobbly smile. "I'm the Blobfish Hero. And I won't let anyone crush me."

Ten years is a long time in the development of a human being, but for a Quirked individual, it is the crucible in which their entire identity is forged. 

The decade that followed his manifestation was not easy for Izuku Midoriya. Society was not kind to those with Quirks that were visually unappealing or lacked obvious utility. He was subjected to a relentless campaign of bullying, ostracization, and underestimation. The nickname "Blob-Deku" stuck with the tenacity of superglue, following him through elementary and into middle school. 

But Izuku was not the same weeping, helpless boy in the sandbox. He had made a promise to himself, and he possessed a sheer, unrelenting will that bordered on the obsessive. 

If his biology dictated that he was soft, heavy, and slow, he would master those traits to absolute perfection. 

At age seven, realizing that conventional strength training yielded almost zero results—his lipid-jelly body refused to develop rigid, striated muscle like a normal human—he asked his mother to enroll him in a dojo. He was rejected by three karate schools and a kickboxing gym before an old, retired Pro Hero who taught traditional Judo and Aikido took him in.

"Martial arts are not about who can punch the hardest, Midoriya," his sensei, a withered man with a turtle-shell Quirk, had told him on his first day. "It is about physics. It is about momentum, leverage, and the redirection of kinetic energy."

Izuku took to the teachings like a fish to water. 

He learned the exact mechanics of his own body. He discovered that while his resting state was soft and gelatinous, he could consciously control the distribution of his lipid mass. By shifting his internal center of gravity, he could make himself virtually impossible to throw or tackle. 

In a sparring match, an opponent would charge him, attempting a takedown. Izuku would simply root his feet, relax his upper body, and shift all his gelatinous density into his lower half. The opponent would hit him and bounce off, their kinetic energy absorbed by the jelly, while Izuku stood entirely immovable, a smiling Buddha of flesh. 

Then came the redirection. Because he could not strike with rigid force, Izuku learned to use his opponent’s momentum against them. He became a master of grappling. His hands, though lacking hard knuckles, were massive and thick. Once he grabbed hold of a wrist or a lapel, his soft flesh would mold perfectly around the joint, creating a vacuum-like seal that was incredibly difficult to break. He would absorb an incoming blow, capture the limb, and use the attacker's own recoil to throw them to the mat.

Alongside his physical training, Izuku trained his mind. His Hero Analysis for the Future notebooks grew from Volume 1 to Volume 13. He studied Heroes and Villains obsessively, categorizing Quirks, analyzing weaknesses, and understanding the fluid dynamics of combat. He realized early on that knowledge was the only weapon he could wield with lethal efficiency. 

By the time he reached fourteen, Izuku Midoriya was a walking contradiction. 

To the untrained eye, he looked like a prime target for bullying. He was chubby, his uniform fitting snugly around a soft, prominent belly. His cheeks were still round, his limbs thick and devoid of any visible muscle tone. He slouched slightly, his posture relaxed to allow his heavy body to settle comfortably. 

But underneath the soft, squishy exterior lay the mind of a tactical genius and the defensive capability of a military-grade bunker. 

"Since you're all third years, it's time for you to think seriously about your future!" 

The homeroom teacher of Aldera Junior High stood at the front of the classroom, waving a stack of career aptitude papers. Izuku sat near the back, his head down, meticulously sketching the schematics of Kamui Woods' binding techniques in his notebook. 

"I'll pass out handouts for your future plans now, but..." The teacher paused, a smirk crossing his face. "You're all pretty much planning to go into the hero course, right?"

The classroom erupted. Students cheered, showing off their Quirks. Fingers elongated, water sprouted from heads, small objects floated in the air. 

"Yes, yes, you all have wonderful Quirks! But using your powers in school is against the rules!" the teacher scolded half-heartedly. 

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

The voice cut through the noise like a serrated knife. Katsuki Bakugo sat with his feet propped up on his desk, leaning back with a look of supreme arrogance. He had grown taller, his muscles lean and tightly coiled, his spiky ash-blond hair framing a face that was permanently set into a scowl. 

"I'm not gonna be stuck at the bottom with the rest of these rejects," Bakugo declared, ignoring the angry shouts from his classmates. "I completely aced the mock tests. I'm the only one here with the stuff for U.A. High School. I'm gonna surpass All Might and become the top hero, and my name'll be inscribed on the list of top earners!"

The teacher looked down at his clipboard. "Oh, yeah. Midoriya wanted to go to U.A., too, right?"

The classroom froze. All eyes turned to the back row, landing on the pudgy, green-haired boy hunched over his desk. 

For a second, there was silence. Then, the entire room exploded into uproarious laughter. 

"Midoriya? No way!"

"You can't get into U.A. by just being a fatass!"

"What's he gonna do, bounce the villains away?"

"They don't have a Hero Course for human waterbeds!"

Izuku didn't flinch. He didn't cry, nor did he shrink back into his chair. He merely closed his notebook, calmly placing his pen down. Over the years, the insults had lost their sting. They were just words, sound waves vibrating against his eardrums, far less impactful than the physical blows he had learned to absorb. 

"They got rid of that rule," Izuku said, his voice steady, carrying over the dying laughter. "There's no rule against those with non-combat Quirks entering the Hero Course. It's just a precedent. I can still take the exam."

SMASH!

Bakugo’s fist slammed onto Izuku’s desk, an explosion detonating against the wood, splitting the desk in half and sending Izuku’s notebooks flying. The force of the blast sent Izuku tumbling backward out of his chair, landing on the linoleum floor with a heavy, unceremonious thud. 

"Listen up, Deku!" Bakugo snarled, leaping over the ruined desk and standing over Izuku, smoke rolling off his palms. "You're worse than the rest of these rejects! You're completely unsuited for combat! You've got a gross, squishy body that can't even throw a real punch! You think you can rub shoulders with me?!"

Izuku looked up at Bakugo. There was a time when looking into those red eyes filled him with paralyzing terror. Now, Izuku just saw a kinetic anomaly. He saw heat, pressure, and an easily predictable attack pattern. 

"I'm not trying to compete with you, Kacchan," Izuku said, slowly pushing himself to his feet. His movements were lethargic, entirely lacking urgency. "But... it's been my goal since I was little. And I won't know unless I try."

"Try?!" Bakugo yelled, grabbing Izuku by the collar of his uniform. "What can you even do?! You're just a punching bag!"

"Stop it, Bakugo!" the teacher finally intervened, though he sounded more annoyed by the property damage than the assault. "Take your seat. Midoriya, get a spare desk from the hall."

Bakugo shoved Izuku backward. Izuku’s body naturally absorbed the shove, his feet sliding back an inch, but his torso remained upright, his gelatinous mass shifting to anchor him. Bakugo glared at him, a muscle twitching in his jaw. There was something about Deku that infuriated him beyond words. The boy never looked scared anymore. He just looked... analytical. 

The school day ended. The afternoon sun cast long, golden shadows through the empty classroom. Izuku was packing his bag, slipping his slightly singed notebook inside, when a hand clamped down on his shoulder. 

"We're not done talking, Deku."

Izuku sighed, not turning around. "I need to go home, Kacchan. My mom is making katsudon."

Bakugo snatched the notebook out of Izuku’s hand. He looked at the cover. "Hero Analysis for the Future? Seriously? You're still playing pretend?"

"Give it back," Izuku said, his tone shifting. It wasn't a plea; it was a firm, flat demand. 

Bakugo sneered. He pressed his palms together, sandwiching the notebook between them. A sharp crackle echoed in the room, and a burst of fire engulfed the book. The smell of burning paper filled the air. Bakugo tossed the charred, smoking remains out the open window. 

"Most top-tier heroes have stories about them from their school days," Bakugo said, leaning in close. "I want the shine of being able to be called the only student to make it into U.A. from this mediocre city public middle school. I mean, I'm a perfectionist." 

Bakugo placed a smoking hand heavily onto Izuku's shoulder. The heat was intense, singing the fabric of the uniform, causing the flesh underneath to recoil slightly from the temperature. Extreme heat was Izuku's kryptonite. It melted his lipid-jelly, making it runny and destroying its shock-absorbing properties. 

"So, here's a word of advice, nerd," Bakugo whispered, a menacing grin on his face. "Don't even think of applying. If you want to be a hero so badly, there's a quick way to do it. Believe that you'll be born with a decent Quirk in your next life, and take a swan dive off the roof!"

Bakugo’s lackeys, standing by the door, snickered. 

Izuku stopped moving. The air in the room seemed to drop ten degrees. 

He turned his head slowly, his emerald eyes locking onto Bakugo's. There was no fear. There was no sadness. There was only a cold, unyielding, deep-sea pressure. 

"You shouldn't tell people to kill themselves, Kacchan," Izuku said softly. "If I actually did it, you would be charged with instigating suicide. That would go on your permanent record. U.A. doesn't accept criminals into the Hero Course."

Bakugo's smile vanished. His eyes widened slightly at the cold logic, before his face contorted into pure, unadulterated rage. 

"What did you say to me?!" Bakugo roared. He pulled his right arm back, sparks wildly flaring in his palm. He wasn't holding back this time. He aimed a full-powered, right-hook explosion directly at Izuku’s stomach. "I'll kill you!"

BOOM!

The explosion tore through the quiet classroom, shattering the nearest window pane and kicking up a cloud of chalk dust. The sheer concussive force rattled the desks, the deafening crack echoing down the hallway. 

Bakugo’s lackeys winced, stepping back. "Dude! You went too far! You're gonna kill him!"

The smoke slowly cleared. 

Bakugo was standing with his arm outstretched, his fist buried deep into Izuku’s midsection. His breathing was heavy, his teeth bared in a feral grimace. 

But Izuku Midoriya was still standing. 

He hadn't moved a single inch backward. His feet were rooted to the floor. His uniform shirt was blown open, completely incinerated at the impact point, revealing the pale, soft flesh of his stomach. 

Bakugo's fist was sunk almost three inches deep into the lipid-jelly of Izuku's gut. 

Time seemed to slow down. Izuku looked down at Bakugo's fist. He could feel the heat, which stung, but the concussive force—the kinetic energy of the explosion that should have ruptured his organs—was currently traveling through his body. Like a pebble dropped into a calm pond, the shockwave rippled outward through Izuku's gelatinous mass, vibrating his shoulders, his chest, his legs, until it dissipated harmlessly into the floor beneath his feet. 

The pressure inside his stomach instantly equalized. The displaced gelatin, heavily compacted by the explosive force, violently rejected the foreign object. 

BOING.

With a sound exactly like a high-tension rubber band snapping back into place, Bakugo’s fist was violently expelled from Izuku’s stomach. 

The recoil was massive. Bakugo, who had leaned all of his weight into the punch, had his own explosive momentum fed directly back into his arm. The force hyper-extended his elbow with a sharp crack, and the kinetic backlash sent him flying backward. 

Bakugo’s feet left the ground. He sailed through the air, crashing spectacularly into a cluster of desks, tumbling head over heels until he slammed back-first against the chalkboard, groaning in pain as chalk dust rained down on his head. 

The two lackeys at the door screamed, bolting down the hallway in sheer terror. 

Izuku stood amidst the smoke, his scorched shirt fluttering around his unharmed stomach. The soft flesh jiggled one last time before settling back into its pudgy, unthreatening shape. 

He walked over to the window, leaning out to locate his burnt notebook in the koi pond below. 

"I told you, Kacchan," Izuku said quietly, not even looking back at the groaning boy tangled in the broken desks. "I'm not trying to compete with you. You're a sword. You're meant to cut things." 

Izuku turned his head, looking over his shoulder. The sunlight caught the determined glint in his eye, casting his soft, rounded features in a silhouette of immovable stone. 

"But I'm an anvil," Izuku said. "And no matter how hard you strike, you will break before I do."

He picked up his yellow backpack, slinging it over his shoulder, and walked out of the classroom, leaving Bakugo staring at the ceiling in stunned, furious silence. 

Izuku Midoriya wasn't fast. He wasn't flashy. He didn't have a power that could shatter buildings or manipulate the elements. He was heavy, he was squishy, and he looked like a joke. 

But as he walked down the hallway, retrieving his soggy notebook from the pond and heading out into the sprawling city of Musutafu, he knew one thing for certain. 

The world was about to find out exactly what happened when you put the squishiest hero under pressure.

The afternoon sun baked the concrete of Musutafu, creating a shimmering mirage of heat that distorted the skyline. Izuku Midoriya walked alone beneath the towering overpass, the rhythmic slapping of his red sneakers echoing in the cool, damp shade of the tunnel. 

His damp, slightly singed Hero Analysis for the Future: Volume 13 was safely tucked into his yellow backpack. Despite the violent confrontation with Bakugo earlier that afternoon, Izuku’s heart was remarkably calm. For ten years, he had been a victim of his own biology, mocked for a body that was softer, rounder, and slower than everyone else's. But today, the anvil had broken the hammer. He had taken a point-blank explosion from Katsuki Bakugo, the most volatile student in their ward, and simply bounced it back. 

He patted his stomach. Through the fabric of his fresh gym shirt, his flesh felt cool, dense, and perfectly intact. The blobfish Quirk was not a curse. It was a puzzle, one that he was finally beginning to solve. 

If I can master the kinetic redirection, Izuku thought, his mind already spinning with algebraic formulas regarding impact and momentum, I could theoretically scale my defense to handle blunt-force impacts from Quirks with ten, maybe twenty times Kacchan's output. The only issue is piercing damage. If a villain has a sword or claws, my lipid-armor won't stop them from severing—

A wet, sickening slurping sound echoed through the tunnel. 

Izuku stopped. The hairs on the back of his neck prickled. The smell hit him first—a rancid, suffocating stench of open sewage, rotting garbage, and stagnant river water. 

He turned around slowly. Rising from a manhole cover a few yards away was a nightmare made liquid. A towering mass of dark, putrid sludge piled upward, defying gravity as it formed into a towering, gelatinous wall of mud and filth. Two massive, bulbous eyes rolled within the liquid, locking onto Izuku with a predatory gleam. A jagged maw of jagged teeth formed in the center of the muck.

"A medium-sized meat-suit," the Sludge Villain gurgled, his voice sounding like a drowning man speaking through mud. "Perfect. You’ll make a fantastic cloak, kid. Just stand still and let me in!"

Izuku’s eyes widened, but the panic in his brain was instantly overridden by a cold, analytical surge. Liquid-based Villain. Highly mobile. Suffocation hazard. I have no offensive output to disperse his mass. Retreat is the only viable option.

Izuku turned to run, but his heavy, pudgy legs were no match for the villain's explosive, fluid speed. 

Like a tidal wave crashing against a breakwater, the Sludge Villain lunged forward, a massive tendril of dark muck slamming into Izuku’s back. The force knocked Izuku off his feet, sending him sprawling onto the concrete. Instantly, the villain was upon him, the horrific sludge wrapping around Izuku’s arms, his torso, and surging toward his face. 

"Don't worry," the villain hissed, his teeth right next to Izuku's ear. "It'll only hurt for about forty-five seconds. Then it'll all be over!"

The sludge forced its way over Izuku's mouth and nose. The taste was unimaginable—like swallowing stagnant pond water filled with battery acid. Izuku’s lungs burned, begging for oxygen. He reached up, his thick, heavy hands grabbing at the sludge in a desperate attempt to tear it away from his face, but his fingers simply phased through the liquid, unable to find purchase. 

I can't breathe... I can't hit him... 

"You can't grab me, kid!" the villain laughed. "I'm fluid! Now stop squirming and let me take over!"

But then, biology took the wheel. 

Izuku Midoriya possessed the genetic mutation of Psychrolutes marcidus. The deep-sea blobfish. Under extreme duress, specifically when threatened with a lack of oxygen or a physical crushing force, the blobfish’s body initiates an autonomic defense mechanism. 

As the Sludge Villain tightened his grip, trying to squeeze Izuku into submission, Izuku’s pores violently dilated. In an instant, his skin secreted a thick, highly viscous, hyper-slick layer of natural mucous. 

The villain paused, a confused gurgle rumbling in his liquid chest. "What the... what is this?"

The sludge trying to force itself down Izuku’s throat suddenly found zero friction. The villain couldn't grip Izuku’s face. He couldn't grip Izuku’s arms. 

"Why can't I hold onto you?!" the villain roared, frustrated, trying to constrict his fluid body tighter around the boy's midsection. 

That was his second mistake. 

By applying intense pressure around Izuku's waist, the villain inadvertently triggered Izuku’s primary Quirk function. Izuku’s internal lipid-jelly compressed, instantly becoming dense and highly pressurized. His round body tightened, turning into an incredibly firm, frictionless wedge. 

Izuku didn't even have to fight back. He simply wriggled his shoulders. 

With a loud, cartoonish SCHLURP, Izuku shot out of the Sludge Villain's grasp like a wet bar of soap squeezed too hard in the shower. He slid ten feet across the concrete tunnel floor, covered in his own protective slime, gasping greedily for air. 

"You little brat!" the villain screamed, enraged. He reared back, forming his sludge into a massive, spiked whip, preparing to skewer the boy. "I'll just tear you apart instead!"

Izuku braced himself, crossing his arms over his face, ready to test just how much piercing damage his blubber could take. 

CLANG!

The manhole cover the villain had emerged from suddenly blasted into the ceiling of the tunnel, shattering the concrete. A massive, towering figure landed in the center of the tunnel, shaking the earth with his arrival. 

"FEAR NOT, CITIZEN!" 

The voice was a booming baritone, radiating absolute authority and unyielding optimism. Izuku peered through his arms, his breath catching in his throat. 

Standing in the shadows of the tunnel, illuminated only by the faint light from the street, was a man with impossible musculature. His blonde hair swept back into two massive tufts, a brilliant, shining smile practically glowing in the dim light. 

"BECAUSE I AM HERE!" 

All Might. The Symbol of Peace. The Number One Hero in the world. 

The Sludge Villain recoiled in absolute terror. "All Might?! No! How did you find me?!"

The villain lashed out, throwing a desperate, massive wave of sludge toward the hero. 

All Might didn't dodge. He simply pulled back his right arm, the muscles bulging and contracting with terrifying, awe-inspiring power. He planted his feet, twisting his hips, and unleashed a punch into the empty air. 

"TEXAS... SMASH!"

The wind pressure generated by the sheer physical force of the punch was catastrophic. A localized hurricane erupted in the tunnel. The air compressed and exploded forward in a roaring shockwave. The Sludge Villain didn't even have time to scream before the wind pressure hit him, tearing his fluid body apart at the molecular level, splattering him against the ceiling and walls of the tunnel in a million harmless drops of muck. 

The wind hit Izuku next. Any normal person would have been picked up and thrown fifty feet down the tunnel, suffering severe abrasions from the concrete. 

But Izuku's heavy, gelatinous body acted as the perfect anchor. His soft tissue rippled wildly under the gale-force wind, absorbing the kinetic energy of the storm. He slid backward a few inches, his feet rooted to the ground, but he didn't fall. 

As the wind died down, the tunnel fell silent, save for the dripping of the defeated villain. 

Izuku stood there, blinking rapidly, entirely coated in a mixture of villain-sludge and his own defensive mucous. 

All Might turned to him, his smile unwavering, though his sharp blue eyes registered a flicker of surprise. "Well, well! I must apologize, young man! I didn't mean to catch you in the crossfire of my attack! But color me impressed! Most men would have been blown away by that wind pressure, but you stood your ground like a mountain!"

Izuku couldn't speak. His brain was short-circuiting. All Might. He's right here. He's talking to me. His Quirk, it's not just strength, it's kinetic manipulation through raw muscular density—

"Ah! You seem to be in shock!" All Might boomed, rummaging through his pockets. He pulled out a couple of empty two-liter soda bottles and began rapidly scooping up the unconscious Sludge Villain. "Perfectly understandable! But fear not! The villain is captured, and you are safe!"

"A-A-An autograph!" Izuku finally stammered, frantically reaching into his backpack. He pulled out his damp notebook, flipping past the charred pages to a clean one. He offered it with trembling, squishy hands. "P-Please!"

"HAHAHA! A fan! Excellent!" All Might snatched the notebook, producing a massive marker out of thin air, and signed a two-page spread with blinding speed. He handed it back. "There you go, young citizen! Now, I must be off to deliver this miscreant to the authorities!"

All Might crouched, preparing to leap. 

"Wait!" Izuku blurted out, stepping forward. 

All Might paused. "No time to wait, my boy! Pro Heroes are constantly fighting time as well as enemies!"

"Just one question!" Izuku yelled, the words tearing out of his throat before his anxiety could stop them. He looked down at his own pudgy hands, at the soft belly that rested over his belt. "I... I have a mutation Quirk. I don't have super strength. I don't have explosive power. I'm just... soft. My body is just built to take hits, but I can't hit back."

Izuku looked up, tears pricking the corners of his eyes, his voice trembling with a decade of suppressed desperation. 

"Can someone without an attacking Quirk ever become a hero? Can someone who's just a shield ever stand on the same stage as you?"

All Might froze. The wind seemed to stop howling outside the tunnel. 

The towering hero looked at the boy. He looked at the boy's round, unassuming face. He noticed the burns on the boy's uniform—burns that hadn't left a mark on the skin beneath. He remembered how the boy hadn't budged an inch against the Texas Smash. He remembered the slick, defensive mucous that had prevented the villain from possessing him. 

All Might didn't see a helpless child. He saw a survivor. 

Slowly, All Might relaxed his posture. His smile softened from his trademark, boisterous grin into something genuinely warm and deeply respectful. 

"A hero," All Might said, his voice dropping into a resonant, serious tone, "is not defined by the violence they can inflict upon the world. A hero is defined by the violence they are willing to endure so that others do not have to."

Izuku's breath hitched. 

"There are many kinds of heroes, young man," All Might continued, pointing a massive finger at Izuku's chest. "Rescue heroes, underground heroes, defense specialists. If your body is built to be a shield, then what a magnificent shield it is. You survived a villain attack today through your own physical resilience. That is no small feat."

All Might placed a hand on his hip, his smile returning to its full, blazing glory. 

"You may not have the power to blast a villain through a building. But if you train your mind, and you push your defense to its absolute limits, you can become the immovable object that protects the innocent. Yes, young man. You can be a hero."

The words struck Izuku with the force of a physical blow, but this time, it was a blow that healed. The dam broke. Izuku dropped to his knees, his thick hands covering his face as he sobbed openly, his heavy body shaking with a decade of released tension. 

You can be a hero.

All Might watched the boy for a moment longer. In his pocket, he felt the heavy burden of One For All, the torch of power that he needed to pass on. He needed a successor. He needed someone with a heroic heart to take up his mantle. 

But as he looked at the boy crying tears of joy on the pavement, All Might realized something. This boy didn't need One For All. Giving this boy a power that would shatter his bones and alter his destiny felt wrong. This boy already had everything he needed. He just needed the permission to try. 

"Train hard, young man!" All Might called out, crouching low. "The path of a shield is a heavy one! But I look forward to seeing the hero you become!"

With a mighty leap, All Might vanished into the sky, leaving Izuku alone in the tunnel. 

Izuku wiped his eyes, smearing the remaining slime across his face. He looked down at the notebook in his hand, at the sprawling signature of his idol. He didn't need a fiery explosion. He didn't need super strength. 

He was going to U.A. High School. And he was going to be the greatest shield the world had ever seen. 

Ten Months Later.

The gates of U.A. High School towered over the incoming swarms of middle school students like the monolithic pillars of a modern colosseum. It was the premier hero academy in Japan, a fortress of glass and steel where legends were forged. 

Izuku Midoriya stood at the bottom of the front steps, staring up at the H-shaped building. 

He looked, fundamentally, exactly the same as he had ten months ago. He was still chubby. His face was still round. His limbs were still soft. To the naked eye, the ten months of rigorous, agonizing training he had put his body through had yielded no visible results. 

But Izuku knew the truth. 

Underneath his skin, his blobfish biology had been pushed to its absolute limits. He had spent the last ten months at Dagobah Municipal Beach. He hadn't cleared the trash—he didn't have the physical strength to lift the massive refrigerators or rusted cars. Instead, he used the trash to train his defense. 

He had set up brutal gauntlets. He had rigged pendulums of heavy scrap metal to swing down and smash into his ribs, teaching his body to instinctively shift its gelatinous mass to absorb kinetic energy from different angles. He had practiced his Pressure Shift, holding his breath and compressing his fat cells until his flesh felt as hard as a rubber tire. He had trained his stamina, jogging miles along the sand until his heart could pump efficiently despite his heavy weight. 

He was as ready as a boy made of jelly could ever be. 

"Outta my way, Blob."

The rough shoulder bump didn't even make Izuku sway, but the voice made him turn. Katsuki Bakugo walked past him, his hands shoved deep into his pockets, his red eyes glaring forward. Bakugo had avoided Izuku entirely since the incident in the classroom, treating him with a cold, infuriated distance. 

"Good morning, Kacchan," Izuku said pleasantly. 

Bakugo just scoffed, storming up the steps. 

Izuku smiled slightly and began his own trek up the wide concrete stairs. He was so busy running through his tactical analysis in his head that he didn't notice the uneven step near the top. His heavy red sneaker caught the lip of the concrete. 

Izuku didn't fall—his low center of gravity and natural balance easily corrected the stumble. But the girl walking right beside him wasn't so lucky. 

Startled by his slight trip, the girl with a brown bob and permanent blush stickers on her cheeks lost her footing. She pitched forward, a startled yelp escaping her lips as her face hurtled toward the unforgiving concrete. 

Izuku moved with surprising fluidity. He didn't reach out to grab her—he knew his hands lacked the firm grip strength to catch her by the arm without hurting her. Instead, he stepped directly into her path, turning his body and consciously relaxing his internal pressure. 

The girl crashed chest-first into Izuku's back. 

Instead of slamming into a rigid spine, it was like she had fallen into a massive, heavily insulated memory-foam mattress. Izuku’s flesh rippled, his blobfish lipid-jelly absorbing all of her forward momentum instantly, cushioning her fall perfectly. 

"Woah!" the girl gasped, bouncing slightly off his back and landing safely on her feet. She patted her chest, her wide brown eyes staring at Izuku in awe. "Oh my gosh, I'm so sorry! But... wow! You are so squishy!"

Izuku turned around, his cheeks flushing pink. He wasn't used to people calling him squishy as a compliment. "O-Oh! Um! Are you okay? I'm sorry, I tripped, and then you tripped, and I just—"

"I'm perfectly fine!" she beamed, clasping her hands together. "Thanks to you! I'm Ochaco Uraraka. It would've been bad luck to fall right before the exam, huh?"

"I-I'm Izuku Midoriya," he stammered, rubbing the back of his neck, his flesh squishing under his fingers. 

"Well, thanks for the cushion, Midoriya! Good luck in there! Let's do our best!" She gave him a cheerful wave and jogged into the building. 

Izuku stood there for a moment, a goofy smile spreading across his face. I talked to a girl. And she didn't think I was gross. He clenched his soft fists. I have to pass this exam.

The written exam had been a breeze. Izuku’s obsessive hero analysis had given him a near-encyclopedic knowledge of Quirk laws, physics, and tactical rescue scenarios. But as he stood before the massive, towering gates of Battle Center B, dressed in his green tracksuit, the reality of the practical exam hit him like a ton of bricks. 

Present Mic had explained the rules perfectly in the auditorium. It was a mock urban battle. There were three types of villain robots worth one, two, and three points respectively. The goal was to destroy them and rack up points. 

Destroy them.

Izuku looked down at his soft hands. He couldn't punch through steel. He couldn't blast them with fire. He couldn't slice their wiring. 

"START!" Present Mic's voice blasted over the loudspeakers. "What are you waiting for?! There are no countdowns in real life! Run, run, run!"

The crowd of examinees surged forward. Explosions, lasers, and battle cries filled the air as the teenagers flooded the fake city. 

Izuku took a deep breath, shifting his weight, and jogged into the fray. 

Chaos reigned supreme. Buildings crumbled as massive, tank-like robots rolled through the streets. Izuku rounded a corner and came face-to-face with a Two-Pointer. The machine locked onto him, its red optical sensor flashing as it raised a massive, hydraulic fist. 

Target acquired, the robot's mechanical voice droned. 

The fist shot forward like a cannonball. 

Izuku didn't dodge. He planted his feet, widening his stance. He took a sharp breath, compressing the lipid-jelly in his chest, preparing for the impact. 

CLANG!

The steel fist slammed directly into Izuku’s sternum. The sheer kinetic force of the blow was enough to shatter the ribs of a normal human. But Izuku’s chest simply swallowed the fist. The metal sank four inches deep into his blubber, the force of the blow rippling outwardly across his entire torso in a wave of jiggling flesh. 

"Impact absorbed," Izuku muttered through gritted teeth. "Now... Recoil!"

Izuku released his breath and forcefully expanded his compressed fat. 

BOING!

The hydraulic fist was violently ejected from Izuku’s chest. The robot, unable to compute the sudden reversal of kinetic energy, stumbled backward, its treads slipping on the asphalt. 

"Now's my chance!" Izuku yelled, lunging forward. He threw his arms around the robot's central chassis, using his incredible body weight to wrestle the machine to the ground. He couldn't punch it, but he was heavy. Very heavy. 

He pinned the robot down, his thick fingers desperately digging into the seams of its neck-plating, trying to rip out the wiring. It was agonizingly slow work. His fingers kept slipping. 

ZAP!

A beam of bright, sparkling light shot past Izuku's ear, striking the robot's exposed neck and blowing its head clean off. 

Izuku fell backward as the robot powered down. He looked up to see a boy with blonde hair and a sparkling belt striking a pose on a nearby fire escape. 

"Mercí for the assist, mon ami!" the boy called out, winking before leaping away to find another target. 

Izuku scrambled to his feet, a cold sweat breaking out on his forehead. He took the points. I immobilized it, but I didn't destroy it. That means... I have zero points.

Panic, cold and sharp, pierced through Izuku's chest. He began to run wildly through the streets. Everywhere he looked, robots were being smashed, frozen, or exploded by students with incredible, flashy Quirks. 

He found a One-Pointer. He tackled it, using his squishy body to clog its gears, wrestling it down until its motor burned out. 

One point.

He found another One-Pointer. He lured it into charging him, using his shock-absorption to bounce it into a brick wall where it shattered. 

Two points.

"Six minutes remaining!" Present Mic's voice echoed. 

Izuku leaned against a lamppost, panting heavily. The constant kinetic absorption was taking its toll. While his body could handle the impact, the energy had to go somewhere. The friction of the absorbed blows was heating up his internal jelly, making him feel sluggish, hot, and nauseous. Extreme heat was his weakness, and he was cooking himself from the inside out. 

Two points. I only have two points. It's not enough. It's nowhere near enough.

The words of the doctor from ten years ago echoed in his mind. Useless. A punching bag. No offensive capability.

Tears pricked Izuku's eyes. Was All Might wrong? Was a shield truly useless in a world that only valued swords? 

Suddenly, the ground beneath Izuku's feet violently trembled. 

The tremors grew rapidly, shaking the glass out of the nearby buildings. The sky darkened as a shadow fell over the mock city. 

At the end of the main street, the buildings exploded outward. Dust and debris rained down like shrapnel. Emerging from the smoke, towering higher than the tallest skyscrapers in the arena, was a mechanical leviathan. 

The Zero Pointer. 

It was a monstrosity of steel, gears, and raw, destructive power. Its massive treads crushed roads into dust, and its gigantic, clawed hands swatted away buildings as if they were made of cardboard. 

"Less than two minutes remaining!" Present Mic announced. 

The other examinees didn't hesitate. The moment they saw the colossal machine, they turned and ran in the opposite direction. There was no point in fighting it. It was an impossible obstacle, meant to test their common sense to retreat. 

Izuku turned to run. His heavy legs felt like lead. His mind screamed at him to follow the others, to survive, to maybe find one last One-Pointer in the alleyways. 

"Oww... my leg!"

The voice was faint, barely audible over the roaring engines of the Zero Pointer. 

Izuku stopped dead in his tracks. He turned his head, his wide green eyes scanning the dust cloud. 

There, fifty yards away, directly in the path of the advancing colossus, was the brown-haired girl. Uraraka. She was trapped under a massive slab of concrete that had fallen from a nearby building, pinning her leg to the ground. She was struggling frantically to lift it, but it was too heavy. 

Above her, the Zero Pointer raised its massive, metallic foot, preparing to take a step that would crush her, the concrete, and the street into powder. 

In that fraction of a second, Izuku Midoriya did not think about points. He did not think about U.A. High School. He did not think about his lack of offensive power, or the limits of his heat-stressed blubber. 

He didn't think at all. His body moved on its own. 

With a roar that tore from the very bottom of his soul, Izuku sprinted toward the girl. He pushed his heavy legs harder than he ever had in his life, his red sneakers slamming against the asphalt, leaving small craters in his wake. 

Uraraka looked up, tears streaming down her face as the shadow of the massive foot fell over her. "Help..."

Izuku dove. 

He didn't dive to pull her out—there was no time, and the rock was too heavy. He dove directly over her, placing his body between the crushed girl and the descending foot of the mechanical god. 

Izuku hit the ground on all fours, positioning himself like a turtle over Uraraka. 

Deep sea pressure, Izuku thought, his mind achieving a state of hyper-clarity. The blobfish survives at the bottom of the Mariana Trench. It survives pressures that would crush a nuclear submarine into a tin can. To survive, I cannot fight the pressure. I must become it.

Izuku took the deepest breath of his life. He closed his eyes. 

He consciously relinquished every single ounce of tension in his skeletal muscles. He allowed his blobfish DNA to fully overtake his biology. In a split second, Izuku’s body underwent a massive, localized expansion. His lipid-jelly surged, thickening, multiplying its density exponentially. 

To Uraraka, it looked like the boy above her had suddenly swollen into a massive, dense dome of pale flesh. He became a living, breathing airbag, a mountain of unyielding blubber. 

The foot of the Zero Pointer came down. 

KRA-KOOM!

The impact was deafening. The shockwave shattered the windows of every remaining building on the block. The street beneath them cratered, asphalt exploding upward in a halo of destruction. 

Millions of pounds of hydraulic force, steel, and gravity slammed directly into Izuku Midoriya’s back. 

Izuku screamed. 

The pain was not from his bones breaking. His bones were currently flexible, bending perfectly under the pressure without snapping. The pain was from the sheer, unimaginable heat of kinetic absorption. The metal foot was sinking into his back, pressing deeper and deeper into his jelly, compressing his entire mass down toward Uraraka. 

Hold it! Izuku roared in his mind, blood vessels popping in his eyes. Do not break! Be the anvil! BE THE ANVIL!

As the pressure mounted, Izuku’s body achieved terminal density. The gelatinous mass could not be compressed any further. The physics equation had to balance. The immovable object had met the unstoppable force. 

And the force lost. 

With a sickening, metallic screech, the bottom of the Zero Pointer’s foot began to warp. The steel plating buckled, unable to crush the dense, hyper-pressurized dome of flesh beneath it. The hydraulic pistons in the robot’s leg whined, over-stressed by the sudden, complete halt of momentum. 

Then, Izuku unleashed the recoil. 

Every single ounce of compressed kinetic energy from a million-pound robot stepping on him was violently, explosively rejected. 

Izuku’s back expanded upward with the force of a tectonic plate shifting. 

BOING-KRAAAACK!

The bottom half of the Zero Pointer’s foot shattered into a thousand pieces of shrapnel. The sheer upward force of the recoil shot through the robot's leg, snapping the knee joint backward. The colossal machine lost its balance, teetering dangerously backward. 

Like a felled redwood, the Zero Pointer crashed onto its back, shaking the entire city layout to its foundations, a massive cloud of dust rising into the sky. 

Silence descended upon Battle Center B. 

The remaining students, who had stopped running to watch in sheer, unadulterated horror, stood with their jaws unhinged. 

Slowly, the dust cleared. 

In the center of a massive crater, Izuku Midoriya was collapsed on his hands and knees. His gym shirt was entirely ripped off his back. His flesh was bright red, violently sunburned from the kinetic heat, steaming slightly in the cool air. He was gasping for breath, his body slowly deflating from its hyper-dense state back into its normal, pudgy form. 

Beneath him, untouched and perfectly safe, Uraraka stared up at him with wide, tear-filled eyes. 

"You..." she whispered, her voice trembling. "You stopped it."

Izuku looked down at her. He offered a weak, wobbly smile, his heavy cheeks lifting slightly. "I... I'm a good cushion."

Then, his eyes rolled into the back of his head, and he collapsed face-first into the dirt, entirely unconscious. 

BEEEEEEP!

"AND THAT'S TIME!" Present Mic's voice blared over the speakers. "THE EXAM IS OVER!"

Two Weeks Later.

The Midoriya apartment was suffocatingly quiet. 

Izuku sat at his desk, staring blankly at the wall. Beside his hand lay a small, circular metal disc. The U.A. acceptance letter. 

He hadn't opened it. He didn't want to. 

He knew what it would say. He had reviewed the scoring metric a thousand times. He had two villain points. Even with the slight curve for physical mutations, two points was dead last. He had failed the written exam's practical application. He hadn't destroyed the Zero Pointer—he had just broken its foot and made it fall over. And even if he had, Zero Pointers were worth exactly that: zero. 

He had saved Uraraka, and he didn't regret it for a single second. If it cost him his dream to save a life, he would pay that price every time. But the reality of his failure was a bitter, heavy pill to swallow. 

"Izuku?" Inko’s soft voice broke the silence. She stood in the doorway, her eyes filled with sympathetic tears. "Sweetie, the letter came. You should open it."

Izuku sighed, picking up the heavy disc. "I know I failed, Mom. It's okay. I'll just apply to general education. I can still be a police officer, or a paramedic."

"Just open it," she urged gently. 

Izuku pressed the button on the top of the disc. 

Instantly, a holographic projection shot out of the device, illuminating the dark room. 

Izuku gasped, falling back into his chair. 

Projected in the air, wearing a sharp yellow suit, was All Might. 

"I AM HERE AS A PROJECTION!" All Might boomed, his smile radiant. 

"All Might?!" Izuku yelled. "Why is he... U.A.?"

"Greetings, young Midoriya!" the hologram spoke directly to him. "You must be wondering why I am here! Well, I have recently accepted a teaching position at U.A. High School! And I must say, seeing your name on the roster of examinees filled me with great anticipation!"

All Might’s face grew slightly serious. "You passed the written exam with flying colors! But the practical exam... you scored a mere two villain points."

Izuku looked down at his lap. I knew it.

"With a score like that," All Might continued, "you would absolutely fail."

All Might pressed a button on a remote in his hand. The projection shifted, showing a video feed. It was Uraraka, standing nervously in front of Present Mic. 

Excuse me! Uraraka's voice echoed in the room. Um, the boy with the green hair? The really squishy one? Can I give him some of my points? He saved my life! He didn't get any points because he stopped that giant robot to protect me! Please!

Izuku’s eyes widened. She had tried to give him her points. 

The projection shifted back to All Might. "A hero course that rejects those who do the right thing is no hero course at all! How can we evaluate a hero on their destructive capabilities alone? The answer is, we don't! The entrance exam had a hidden metric!"

The screen behind All Might lit up, displaying a massive leaderboard. 

"Rescue points!" All Might roared. "Given by a panel of judges for acts of selflessness and bravery! Izuku Midoriya... Sixty Rescue Points!"

Izuku's name shot up the leaderboard, bypassing dozens of other students, settling comfortably in the top ten. 

"For throwing yourself into harm's way, for using your body as an unbreakable shield to protect a fellow examinee... you have proven the exact qualities we look for at this academy!" All Might pointed a finger directly at the camera, his eyes burning with pride. 

"You passed, young Midoriya! Welcome to your Hero Academia!"

The hologram fizzled out, leaving the room bathed in moonlight. 

Izuku sat perfectly still. The silence stretched for a long, agonizing moment. Then, the tears began to fall. They fell thick and fast, dripping off his round, heavy cheeks, splashing onto his desk. 

He hadn't needed a flashy Quirk. He hadn't needed to punch through steel or summon fire. He had used the body he was born with—the soft, squishy, unbreakable body that everyone had laughed at—and he had saved a life. 

Inko ran into the room, throwing her arms around him, weeping just as loudly. 

Izuku hugged her back tightly, his thick, heavy arms wrapping around her in a soft, protective embrace. He closed his eyes, a massive, brilliant smile breaking across his face. 

The Blobfish Hero was going to U.A. And nothing in the world was going to crush him.

The morning classes at U.A. High School were deceptively mundane. Izuku Midoriya sat at his desk, his heavy, soft fingers carefully gripping a pencil as he took notes during Present Mic’s English lecture. It was a surreal dichotomy. The students were being trained to face down natural disasters and super-powered terrorists, yet they still had to conjugate irregular verbs. 

But the underlying hum of anticipation in Class 1-A was palpable. Everyone knew what was coming in the afternoon. 

Hero Basic Training. 

When the bell finally rang, signaling the end of lunch, the atmosphere in the classroom shifted instantly. The idle chatter died down. 

Heavy, rhythmic footsteps echoed down the hallway outside. They were slow, deliberate, and carried an immense, booming weight. 

"I am..." a voice roared from the other side of the door. 

The massive classroom door was thrown open. 

"...coming through the door like a normal person!" 

All Might stood in the doorway, wearing his Silver Age costume—a skin-tight bodysuit of red, white, blue, and gold. He struck a pose, his massive muscles bulging, his radiant smile practically illuminating the room. 

The class erupted. 

"It's All Might!" 

"Wow, he really is a teacher!"

"That's a costume from the Silver Age, isn't it? Its design is so retro!"

Izuku stared, his green eyes wide with awe. Even after their encounters in the tunnel and the holographic acceptance letter, seeing the Symbol of Peace in the flesh never failed to send a jolt of pure adrenaline through his system. 

All Might marched to the podium. "Hero Basic Training! The class that will put you through all sorts of special training to mold you into true heroes! No time to dally! Today's activity is... Combat Training!" 

Beside Izuku, Katsuki Bakugo’s head snapped up. A dark, feral grin stretched across his face. Combat. 

"And to go with that..." All Might pointed a massive finger at the wall. Sections of the wall slid outward, revealing numbered briefcases. "Costumes made based on your Quirk registrations and requests you sent in before school started!"

The class cheered louder than before. 

"After you change, gather in Ground Beta!" All Might commanded. "The clothes make the pro, young men and women! Look the part!"

The locker room buzzed with the sounds of zippers, clasps, and the hum of various support gear powering on. 

Izuku stood in the corner, staring down at his open briefcase. His mother, Inko, had bought him a dark green tracksuit as a base, but U.A.'s support company had heavily modified it based on the exhaustive, fifteen-page specification document Izuku had submitted. 

Izuku pulled the suit on. 

It was a deep, oceanic green, lined with black and white accents. The material was a cutting-edge, hyper-elastic polymer blend. Because Izuku’s body shape could radically alter—expanding outward when absorbing impact or compressing inward during a Pressure Shift—traditional Kevlar or rigid armor would have restricted his movements and ruptured under the strain. The suit stretched flawlessly over his round stomach and thick limbs, feeling like a second skin. 

More importantly, the suit was entirely breathable. His blobfish mutation had a critical weakness to extreme heat, and kinetic absorption generated massive internal friction. To combat this, the support company had integrated microscopic cooling vents into the collar, underarms, and lower back, designed to rapidly vent his body heat. Around his neck sat a respirator shaped somewhat like a stylized rebreather, and on his head, a cowl with protective goggles to keep his own defensive mucus out of his eyes. 

He looked at himself in the mirror. He didn't look like a traditional, chiseled superhero. He still looked round, heavy, and undeniably squishy. 

But he looked like a hero. His kind of hero. 

Izuku stepped out of the tunnel and into the sunlight of Ground Beta, a massive, sprawling replica of a major metropolitan city. 

"They look great on you all!" All Might boomed, standing in the center of the street. "Now, shall we begin, you zygotes?"

"Oh, Deku!" 

Izuku turned. Ochaco Uraraka jogged toward him, wearing a form-fitting pink and black space-suit design, complete with a domed helmet and thick boots. 

"Your costume looks awesome!" Uraraka beamed, looking him up and down. "It really suits you! It looks... tactical! I should have written what I wanted. Mine ended up being a skintight bodysuit. It's a little embarrassing."

"I-I-I think it looks great!" Izuku stammered, his cheeks flushing violently red beneath his cowl. He waved his heavy hands frantically. "I-It fits your Quirk perfectly! Because of the... the mobility!" 

"Now that you're all here, let's get down to business!" All Might announced, drawing their attention. "Today's training will be a two-on-two indoor battle!"

"Without basic training first?" Asui asked, her frog-like tongue resting on her chin. 

"The best way to learn the basics is experiencing them!" All Might replied. "The situation is this: The villains have hidden a nuclear weapon somewhere in their hideout. The heroes must foil their plans. The heroes need to either catch the villains with capture tape or recover the nuclear weapon. The villains need to protect the weapon until time runs out, or capture the heroes."

All Might pulled out a small lottery box. "Teams and opponents will be determined by drawing lots!"

Izuku reached into the box. He pulled out a ball marked with the letter A. 

He looked around. "Team A... who else is A?"

"Me!" Uraraka popped up beside him, holding up an identical ball. "We're a team, Midoriya! This is gonna be great!"

Izuku smiled, a wave of relief washing over his dense body. Working with Uraraka would be comfortable. She was kind, and her Quirk offered incredible tactical versatility. 

All Might plunged his hands into two separate boxes, one marked 'Hero' and one marked 'Villain'. 

"The first teams to fight will be..." All Might pulled out two balls. "These guys! Team A are the Heroes! Team D are the Villains!"

Izuku’s blood ran cold. 

He slowly turned his head toward the crowd. Standing a few feet away, clutching a ball marked with a D, was Katsuki Bakugo. He wore a tight black sleeveless shirt, dark green pants, and massive, grenade-shaped gauntlets on his forearms. 

Beside him stood Tenya Iida, clad in a full suit of gleaming white knight's armor. 

Bakugo didn't look at All Might. He didn't look at Iida. His crimson eyes were locked dead onto Izuku. The sheer, suffocating intensity of his glare felt like a physical weight pressing against Izuku’s chest. Bakugo pounded his right fist into his open palm, a small, violent explosion sparking between his fingers. 

Of course, Izuku thought, his breath catching in his throat. It had to be him.

"Villain Team, go inside and set up!" All Might instructed. "In five minutes, the Hero Team will break in, and the battle will start!"

Inside the dimly lit, concrete building, Tenya Iida paced around the massive, papier-mâché nuclear warhead on the fifth floor. 

"Even if it is training, it pains me to become a villain," Iida muttered, adjusting his helmet. "But I must commit to the role!" He turned to his partner. "Bakugo! We should formulate a defensive strategy. Midoriya's Quirk is a highly resilient mutation, and Uraraka can remove our gravity. If they make it to this room—"

"Shut up, four-eyes," Bakugo growled, cracking his knuckles. He was staring out the window, looking down at the street below. 

"Bakugo, we are a team! We must—"

"I don't care about the weapon," Bakugo interrupted, his voice dropping into a low, terrifying register. "I don't care about the round-face girl. I only care about Deku."

"You are abandoning the objective?!" Iida gasped. 

"That squishy little freak," Bakugo hissed, ignoring Iida completely. "He's been hiding his power for ten years. Making me look like a fool. He thinks he can look down on me? He thinks a bouncy stomach makes him better than me?!" Bakugo turned, his eyes wide and unhinged. "I'm going to find him, and I'm going to break him. You watch the bomb." 

Before Iida could protest, Bakugo stormed out of the room, plunging into the dark, labyrinthine hallways of the building. 

Outside, Izuku was crouched over a blueprint of the building, tracing the pathways with a thick finger. 

"It's a lot to memorize," Uraraka said nervously. 

"We don't need to memorize it all," Izuku replied, his voice calm, entirely devoid of the stutter he usually carried in social situations. When he analyzed combat, his mind became a steel trap. "Kacchan won't wait for us to find the bomb. He's coming straight for me."

Uraraka blinked. "Why do you say that?"

"Because he's Katsuki Bakugo," Izuku said softly. "His pride is his compass. I embarrassed him during the apprehension test. He wants to prove his Quirk is superior. He's going to ambush us the second we step inside."

Izuku stood up, pulling his respirator over his mouth and snapping his goggles into place. 

"Uraraka. When he attacks, he's going to focus entirely on me. I want you to run."

"Run?! But I can't leave you to fight him alone!" 

"You have to," Izuku looked at her, his green eyes serious behind the lenses. "I am going to act as the ultimate decoy. I will hold Kacchan down. You find Iida, locate the weapon, and secure the objective. Our goal is to win the trial, not win a fight."

Uraraka hesitated, looking at his soft, pudgy frame. But she saw the fierce, unyielding determination in his stance. "Okay. I trust you, Midoriya."

"BEGIN!" All Might's voice echoed through the PA system. 

Izuku and Uraraka slipped through a first-floor window. The interior of the building was cast in shadows, the concrete walls damp and claustrophobic. They walked slowly down the main corridor, their footsteps echoing lightly in the silence. 

He's close, Izuku thought, his blobfish biology heightening his sensory awareness. The hairs on the back of his neck stood up. The distinct, sickly-sweet smell of burnt sugar wafted down the hallway. 

Above!

"Uraraka, get back!" Izuku yelled. 

From around the corner, Katsuki Bakugo launched himself out of the shadows. He didn't announce himself. He didn't monologue. He propelled himself forward with an explosion from his left hand, pulling his right arm back. 

He swung his right arm forward, unleashing a devastating, point-blank explosion directly at Izuku and Uraraka. 

BOOM!

The tight confines of the concrete hallway amplified the blast. A shockwave of heat, fire, and kinetic force tore through the corridor. The wall on their left shattered, dust and debris filling the air. 

Uraraka screamed, thrown backward onto her hands and knees by the sheer wind pressure, coughing violently on the smoke. 

"Midoriya!" she cried out. 

The smoke began to clear. 

Standing in the exact center of the hallway, directly in the blast zone, was Izuku. 

Half of his green cowl was singed black, the fabric smoking. The impact had pushed his heavy boots back a few inches, leaving skid marks on the floor, but he hadn't fallen. His arms were crossed over his face in a defensive X. 

He slowly lowered his arms. His thick, pale flesh was coated in a thin, glistening layer of viscous slime. The slime had absorbed the extreme heat of the blast, vaporizing on contact to protect the skin underneath, while his deep-sea lipid-jelly had swallowed the concussive force whole. 

"A surprise attack," Izuku stated, his voice muffled slightly by the respirator. "Exactly as predicted."

Bakugo landed a few feet away, his boots hitting the concrete with a heavy thud. He slowly stood up, smoke rising from his massive gauntlets. His eyes locked onto Izuku, twitching with uncontrollable fury. 

"You didn't even flinch," Bakugo snarled, the veins in his neck bulging. "You gross, squishy freak."

"Go, Uraraka!" Izuku shouted, never taking his eyes off Bakugo. 

Uraraka scrambled to her feet. She looked at Izuku, nodded sharply, and sprinted down the hallway, taking a right turn toward the stairwell. 

Bakugo didn't even turn his head to watch her go. He raised his right hand, sparks popping aggressively in his palm. "Let the extra go. I don't care about the game, Deku. I care about destroying you."

"You can't destroy me, Kacchan," Izuku said, shifting his weight into his combat stance, lowering his center of gravity. "I told you yesterday. I'm an anvil."

"I'LL MELT YOU DOWN TO PUDDLE!" Bakugo roared. 

He lunged. 

Bakugo closed the distance in a fraction of a second, leading with a brutal right hook accompanied by a localized explosion. 

Izuku didn't try to dodge. In a narrow hallway, his heavy body wasn't fast enough to evade. Instead, Izuku triggered his Pressure Shift. He hyper-condensed the fat cells in his left shoulder, turning the squishy mass into a block of ultra-dense biological armor. 

He stepped into the punch. 

Bakugo’s fist slammed into Izuku’s hardened shoulder. The explosion detonated point-blank. The heat singed Izuku’s suit, sending a spike of sharp pain through his nerves, but the kinetic force was entirely halted. It was like Bakugo had punched a mountain. 

Before Bakugo could recoil, Izuku moved. 

Izuku reached out with his thick, heavy right arm. He grabbed Bakugo’s forearm. Unlike a normal hand with bony knuckles, Izuku’s hand lacked hard structure. His thick fingers and palm completely enveloped Bakugo’s arm, the soft flesh molding perfectly around the contours of the gauntlet and limb, creating an airtight, vacuum-like seal. 

Bakugo gasped, trying to pull his arm back. "What the—let go!" 

He couldn't. It felt like his arm was stuck in a massive, heavy vise made of wet clay. 

"In Judo," Izuku said calmly, his green eyes piercing through his goggles, "when an opponent gives you their momentum, you take it."

Izuku twisted his hips. He used Bakugo's own forward momentum, combined with his own immense, shifting body weight. He threw Bakugo over his hip. 

Bakugo went airborne, slamming brutally back-first into the concrete floor. The wind was knocked out of him in a sharp gasp. 

"Damn it!" Bakugo coughed, aiming his free left hand at Izuku’s face. 

BOOM!

Izuku released his grip, leaning his upper body back. The explosion grazed his chest, throwing him back a few feet, allowing Bakugo to scramble up and put distance between them. 

In the monitor room on the ground floor, Class 1-A watched the screens in stunned silence. 

"Midoriya is... he's fighting on par with Bakugo!" Kirishima, a red-haired boy, yelled in disbelief. "But he doesn't have an attacking Quirk! He's just throwing him!"

"He's analyzing Bakugo's movements perfectly," Yaoyorozu noted, her dark eyes tracking Izuku's footwork. "He knows Bakugo always leads with a right hook. He's intentionally taking the hits to his densest areas and using the recoil to counter-attack. It's a flawless defensive strategy."

"But look at Midoriya's suit," the electric boy, Kaminari, pointed. "It's getting burned up. And he looks like he's sweating buckets."

All Might stood silently in the back of the room, gripping a microphone. Young Midoriya is holding his own, All Might thought, but his mutation has a limit. The heat from Bakugo's explosions will eventually break down his lipid-armor. He's on a timer.

Back in the hallway, Izuku was panting heavily. The respirator was helping, but the ambient heat in the concrete corridor was skyrocketing. His internal jelly was growing warm, making him feel sluggish and nauseous. Extreme heat liquefied his defense. 

"What's wrong, Deku?!" Bakugo taunted, wiping blood from his lip, a manic grin spreading across his face. "You look like you're cooking! Is the fat melting off your bones?!"

"Explosions," Izuku panted, his voice steadying, "are just rapid expansions of atmospheric pressure. Heat and kinetic energy."

Bakugo scoffed. "And?"

"And," Izuku stood up straight, letting his arms hang loose. "My body is modeled after Psychrolutes marcidus. The blobfish. It survives at the bottom of the ocean. Do you know what the pressure is like down there, Kacchan?"

Bakugo narrowed his eyes. 

"It's over a thousand times the standard atmospheric pressure," Izuku said, taking a heavy step forward. "My body thrives under pressure. You think your little blasts can crush me? You're just giving me the environment I was born to live in."

The words struck Bakugo's pride like a sledgehammer. The idea that his explosions—his perfect, devastating Quirk—were just feeding Deku's mutation was a concept his ego utterly rejected. 

"I'LL SHOW YOU PRESSURE!" Bakugo screamed. 

He launched himself off the walls, pinballing down the hallway in a flurry of rapid-fire explosions. He moved incredibly fast, attacking Izuku from the left, the right, and above. 

Izuku couldn't track him. He didn't have the speed. 

So, he didn't try. 

Izuku dropped into a crouch, curling his heavy body into a tight ball, shielding his head and neck. He engaged a full-body Pressure Shift, maximizing his density to its absolute peak. 

Bakugo wailed on him. Boom. Boom. Boom. 

Explosions hammered Izuku's back, his shoulders, his arms. The concussive force rattled the building, shaking dust from the ceiling. But Izuku didn't break. His flesh jiggled, rippled, and absorbed every single ounce of kinetic energy. The hallway filled with thick, black smoke, blinding the cameras. 

In the monitor room, the class was shouting in a panic. 

"He's going to kill him!" Uraraka (who had reached the fifth floor) yelled through the comms. 

"Bakugo, stop!" All Might warned over the PA system. "If you continue this reckless assault, I will forcibly end the match!"

In the hallway, the smoke cleared slightly. 

Bakugo was panting, his arms shaking from the sheer output. He looked down. 

Izuku was still there. He was still in his crouch. His suit was badly singed, and there were superficial burns on his exposed skin, but he was completely unbroken. He slowly uncurled, standing back up, his green eyes burning with a terrifying, unyielding resolve. 

Bakugo’s mind fractured. 

He's still standing. The thought echoed in Bakugo's head, drowning out all logic. I threw everything at him, and he didn't even fall down. It's impossible. He's a pebble. He's a quirkless nobody. He can't be better than me!

Bakugo slowly raised his right arm, pointing the massive, grenade-shaped gauntlet directly at Izuku. He reached his left hand over, his fingers wrapping around the metal pin resting on the gauntlet's side. 

"They designed these gauntlets to store my nitroglycerin sweat," Bakugo whispered, his voice trembling with a terrifying blend of rage and desperation. "If I pull this pin, it fires all the stored fluid at once in a hyper-compressed blast."

In the monitor room, All Might's eyes widened. "Young Bakugo, stop! Are you trying to kill him?! If you use that inside, you'll bring the building down!"

"He won't die if he dodges!" Bakugo screamed back at the ceiling. 

Izuku’s eyes widened behind his goggles. He's actually going to do it.

There was nowhere to dodge. The hallway was too narrow. If Izuku moved, the blast would tear through the wall and potentially hit the structural supports, or worse, travel up the stairwell and hit Uraraka. 

Izuku didn't have a choice. He had to take it. But a blast of that magnitude would generate enough heat to instantly melt his lipid-armor and incinerate him. 

He couldn't just absorb it. He had to redirect it. 

"Kacchan! Don't!" Izuku yelled, even as he planted his feet and took a massive, deep breath. 

Bakugo pulled the pin. 

The mechanism clicked. A blinding, searing flash of white light erupted from the gauntlet. 

The explosion was catastrophic. A massive, roaring pillar of fire and concussive force tore down the hallway, disintegrating the concrete floor and vaporizing the moisture in the air. 

At that exact moment, Izuku Midoriya initiated the most extreme application of his Quirk he had ever attempted. 

He flooded his skin with his defensive mucus, creating a thick, hyper-slick layer over his entire body to stave off the initial heat wave. Then, he threw his entire, massive weight backward against the reinforced concrete wall of the hallway. He flattened his body, expanding his soft flesh outward to cover as much surface area on the wall as possible. 

The blast hit him. 

The heat was agonizing, instantly boiling the slime on his skin and singeing the hair off his arms. But the concussive shockwave—the sheer, unadulterated physical force of a localized bomb—slammed into his chest. 

Izuku’s body compressed against the wall. The lipid-jelly flattened, absorbing a frankly impossible amount of kinetic energy. The pressure inside his body skyrocketed to Mariana Trench levels. The building groaned, the walls cracking under the strain. 

Izuku held it for a fraction of a second. Then, he let the physics balance out. 

He expanded. 

KRA-KOOM!

The recoil was Biblical. The concrete wall behind Izuku shattered outward as his body violently rejected the kinetic energy of the blast. 

Izuku shot forward through the dissipating flames like a hyper-dense, hundred-and-sixty-pound cannonball. He moved faster than Bakugo's eyes could track, riding the shockwave of Bakugo's own attack. 

Bakugo barely had time to register the green blur flying through the smoke before Izuku crashed directly into him. 

Izuku didn't punch. He tackled. 

The sheer force of Izuku's heavy, hardened body slamming into Bakugo sent them both flying backward down the hallway, crashing through a wooden door and tumbling into an empty office room. 

They rolled across the floor in a tangle of limbs. 

Before Bakugo could orient himself, Izuku struck. 

Izuku wrapped his thick legs around Bakugo's waist, crossing his ankles and locking them tight. He threw his heavy, fleshy arms around Bakugo's torso, pinning Bakugo's explosive arms tightly to his sides. 

Then, Izuku triggered his Pressure Shift. 

He hyper-condensed every single ounce of fat and jelly in his limbs. His arms and legs transformed from soft, squishy appendages into dense, immovable bands of biological iron. He weighed himself down perfectly, turning his entire body into a hundred-and-sixty-pound straightjacket. 

It was the ultimate, inescapable submission grapple. The Mariana Hold.

"Get... off... me!" Bakugo roared, thrashing wildly. 

But he couldn't move. Izuku’s flesh molded perfectly into every gap in Bakugo’s armor, leaving absolutely zero room for leverage. Bakugo couldn't twist his hips, he couldn't raise his knees, and he couldn't aim his palms. 

"Blast me, Kacchan," Izuku panted, his face inches from Bakugo's ear, his voice strained from the intense heat and pain of the burns on his back. "Do it."

Bakugo sparked his palms, aiming them at Izuku's ribs. 

"If you fire an explosion right now," Izuku said coldly, "at zero range, while completely smothered... the concussive force has nowhere to go. I will absorb the shockwave. But the heat... the heat will have nowhere to vent. You will cook yourself inside your own blast."

Bakugo froze. The sparks in his palms died out. 

He looked up at Izuku's face. Izuku’s cowl was torn, his goggles cracked. His face was smeared with soot and sweat, but his green eyes were utterly calm, staring down at Bakugo with a terrifying, absolute authority. 

For the first time in his life, Katsuki Bakugo felt completely, entirely powerless. He was trapped in a cage made of soft flesh, and no amount of explosive rage could break him out. 

Suddenly, a massive tremor shook the building. The ceiling above them cracked as a loud crash echoed from the fifth floor. 

"Uraraka secured the weapon," Izuku stated, his chest heaving as he maintained the suffocating hold. 

In the monitor room, the silence was absolute. Then, the PA system crackled to life. 

"THE HERO TEAM... WIIIIINS!" All Might's voice boomed, though it lacked its usual boisterous cheer, sounding entirely relieved. 

Izuku closed his eyes. Slowly, agonizingly, he released his Pressure Shift. His arms and legs returned to their soft, heavy state. He uncoiled himself from Bakugo, rolling onto his back on the concrete floor, staring up at the ceiling. 

He had done it. He had taken everything the strongest student in the class had, and he had won. 

Bakugo didn't move. He lay on the floor, his chest heaving, staring blankly at the wall. The reality of his defeat—not just a strategic defeat, but a complete, undeniable physical domination—shattered his worldview into a million irreparable pieces. 

"You..." Bakugo whispered, his voice trembling. "What are you?"

Izuku turned his head, looking at his childhood tormentor. He didn't feel angry. He didn't feel vindictive. He just felt exhausted. 

"I'm Izuku Midoriya," he said softly. "And I'm a hero."

The debriefing in the monitor room was tense. 

Izuku stood near the back, having received a quick patch-up from Recovery Girl's medical bots for the burns on his back and arms. His suit was ruined, but he was fundamentally fine. Bakugo stood on the opposite side of the room, staring at the floor, completely silent. 

"Well, despite the extreme property damage," All Might began, clapping his hands together, "the MVP of this battle is... Young Iida!"

Iida gasped, pointing to himself. "Me?! But I didn't engage in combat!"

"Exactly!" All Might pointed to Yaoyorozu. "Can anyone tell me why?"

Momo stepped forward, her expression serious. "Because Iida was the only one who adapted to the context of the training. Bakugo abandoned his objective for a personal grudge, firing a catastrophic attack indoors that could have killed his opponent and destroyed the payload. Uraraka lost focus mid-battle, and her capture of the weapon was reckless."

She turned her gaze to Izuku. 

"Midoriya," Momo said, her voice respectful but critical. "Your tactical analysis and physical application of your Quirk were absolutely flawless. You successfully disabled a superior offensive threat without dealing lethal damage, executing a perfect capture hold."

Izuku blushed, rubbing the back of his squishy neck. "T-Thank you, Yaoyorozu."

"However," she narrowed her eyes. "You acted as a martyr. You intentionally absorbed a blast that you knew would severely damage your body, relying on your biological resilience to survive. A hero who destroys himself to win a fight is a liability in a protracted war. You must learn to evade, not just absorb."

Izuku blinked. The words echoed Aizawa's warning from the day before. 

He looked down at his heavy hands. She was right. He had survived today, but his blobfish biology wasn't invincible. The burns on his back stung sharply, a reminder of his limits. He was the ultimate shield, but if he stood in the fire too long, he would still melt. 

"A poignant analysis, Young Yaoyorozu!" All Might praised, though his eyes lingered on Izuku with deep, unspoken pride. "We must all learn our limits to surpass them!"

As the class dispersed to prepare for the next matches, Izuku felt a heavy gaze on him. 

He turned. Bakugo was walking toward the door. For a brief second, their eyes met. 

There was no fiery rage in Bakugo’s crimson eyes. There was no explosive screaming. There was only a cold, hollow realization, and a simmering, quiet intensity that was far more dangerous than his anger. 

Bakugo walked out without a word. 

Izuku turned back to the monitors, watching the next teams prepare. He had proven his worth. He had shown the world that a blobfish could survive the pressure. 

But as he watched the monitor, he knew one thing for certain. The pressure was only going to increase from here.
