What if Deku Had the Strongest Creation Quirk Ever

 

The world was not made of solid things.

 

Most people looked at a wooden block, a plastic action figure, or a pane of glass and saw exactly that—a singular, unchangeable object. They saw the skin of the world. But for Izuku Midoriya, the world was a canvas of infinite, vibrating pieces.

 

He was four years old when the curtain was pulled back. He didn’t breathe fire like his father, and he couldn’t pull small objects toward him like his mother. Instead, he learned to speak the language of the universe.

 

It happened on a humid Tuesday afternoon in the playroom of the local preschool. Katsuki Bakugo, the undisputed king of the playground, had just manifested his Quirk a week prior. Tiny, popping explosions crackled in the blonde boy’s palms, earning him the awe of the teachers and the terrified admiration of his peers. In a fit of boisterous, uncontrolled excitement, Katsuki had snatched a mechanical toy bird from the communal toy bin—a favorite of Izuku’s—and squeezed it. A sharp pop echoed through the room. The plastic casing shattered, the cheap internal spring snapped, and the bird was reduced to a blackened, broken lump of melted plastic and bent wire.

 

"Oops," Katsuki had grinned, a feral, unapologetic smirk on his face.

 

The other children laughed. Izuku hadn't laughed. He had knelt on the padded floor, staring at the shattered pieces of the toy. A strange, suffocating pressure began to build behind his green eyes. It wasn't the sting of tears. It felt as though a dam in his mind had suddenly cracked, and a flood of impossible information was rushing into his skull.

 

He didn't just see broken plastic. For a terrifying, exhilarating second, Izuku’s vision inverted. He saw the molecular bonds of the polyurethane casing. He saw the carbon, the hydrogen, the oxygen. He saw the iron in the tiny, bent spring. He could feel the ambient temperature of the room, the trace humidity in the air, the static electricity clinging to the carpet.

 

His brain processed all of it in a fraction of a millisecond.

 

It’s broken, a voice whispered in his mind. So put it back together.

 

Izuku reached out with two small, trembling hands. He didn't touch the broken pieces; he hovered his palms an inch above them. A sudden, blinding flash of emerald light erupted from his hands, accompanied by a sound like crackling static and the sharp, metallic tang of ozone.

 

Katsuki stepped back, shielding his eyes. The teachers gasped, freezing in their tracks.

 

When the light faded, the blackened lump of plastic was gone. In its place, sitting perfectly in the center of Izuku’s palms, was a bird. But it wasn't the cheap, mass-produced toy it had been seconds before. The plastic had been entirely reconfigured into a sleek, seamless shell of reinforced carbon-fiber—a material Izuku had seen on a television documentary about pro-hero support gear. The crude internal spring had been replaced by a meticulously crafted, microscopic clockwork engine, powered by the kinetic energy of a tightly coiled, high-tensile steel mainspring.

 

Izuku didn't know the names of these materials yet. He only knew their shapes, their weights, and how they fit together in the vast jigsaw puzzle of his mind.

 

He gently tapped the bird's head. The mechanical creature whirred to life. It didn't just hop; it spread a pair of articulated, razor-thin wings and took flight, soaring in a perfect, elegant circle around the playroom before landing softly on Izuku’s shoulder.

 

The room was dead silent.

 

Izuku looked up, blinking innocently. Then, a sharp, searing pain drove through his forehead like a hot spike. He clutched his nose as a thick stream of blood poured from his left nostril, dripping onto his All Might t-shirt. His vision swam, his tiny body exhausted by a caloric and neural burn he couldn't comprehend, and he collapsed backward into the soft playmats, unconscious.

 

 

 

Dr. Tsubasa adjusted his round glasses, staring at the clipboard in his hands as if it were written in an alien dialect. He looked up at Inko Midoriya, who was wringing her hands nervously, and then down at the four-year-old boy sitting on the examination table. Izuku was kicking his feet, a piece of gauze stuffed up his nose, happily reading a complex, incredibly dense encyclopedia on metallurgy that the doctor had kept in his office purely for decoration.

 

"Mrs. Midoriya," the doctor finally spoke, clearing his throat. "I have been a Quirk specialist for thirty years. I have seen children who can bend light, children who can speak to animals, and children who sweat nitroglycerin." He paused, glancing at the mechanical bird resting on the doctor's desk. It was still perfectly functioning, its clockwork heart ticking quietly. "I have never seen anything like this."

 

"Is... is he okay?" Inko asked, her voice trembling. "He was asleep for twelve hours after he made that thing. And the nosebleed..."

 

"He is physically fine," Dr. Tsubasa assured her. "But his Quirk... it is not a simple manipulation Quirk. It is not telekinesis, and it is not a standard creation Quirk. Standard creation Quirks, like those that synthesize materials from the user's body fat, operate on biological conversion. Your son didn't use his own biomass. He used the ambient matter around him. He pulled carbon from the plastic, iron from the spring, perhaps even trace elements from the dust in the air, and rearranged their atomic structure to build something entirely new."

 

Inko stared at him, overwhelmed. "Atomic structure? But he's four."

 

"That is where the nosebleed comes in," the doctor said gravely. "His Quirk isn't just the ability to create. It's the ability to comprehend. In order to rearrange atoms, his brain must subconsciously process the blueprints, the physics, the chemistry, and the spatial geometry of the object he is making. The sheer computational power required to do that is astronomical. When he created that bird, his brain drew massively on his body's oxygen and caloric reserves to fuel the neural processing. It quite literally overworked his nervous system."

 

Dr. Tsubasa leaned forward, looking Izuku directly in the eyes. Izuku looked up from the encyclopedia, his bright green eyes sharp and terrifyingly lucid.

 

"Izuku," the doctor said softly. "What do you call this power?"

 

Izuku thought about it for a moment. He looked at his hands. He could still feel the phantom sensation of the universe clicking together, the beautiful, geometric harmony of creation.

 

"Genesis," the boy whispered.

 

"Genesis," the doctor repeated, writing it down. He looked back at Inko. "Mrs. Midoriya. Your son possesses what may theoretically be the most powerful Quirk I have ever documented. The absolute forge. His only limit... is his imagination, and his knowledge. But you must be careful. If he tries to create something too large, or too complex without understanding it, the mental strain could cause a severe cerebral hemorrhage. He must learn to control it. He must learn to understand the world before he tries to reshape it."

 

Inko looked at her son, tears welling in her eyes. She rushed forward, pulling the small boy into a tight, desperate hug. "Oh, Izuku," she sobbed into his curly green hair. "My brilliant, beautiful boy."

 

Izuku hugged her back, but his eyes drifted over her shoulder, staring at the complex x-ray machine in the corner of the room. He could already see how it was built. He could already see how to make it better.

 

 

 

The dynamic on the playground shifted irreversibly the next day.

 

Katsuki Bakugo was not a stupid boy. In fact, beneath his loud, explosive exterior, he was fiercely intelligent and hyper-observant. He had spent his entire short life believing he was the pinnacle of human evolution. His explosion Quirk was flashy, powerful, and destructive. It was the Quirk of a top-tier Hero. He was the main character. Everyone else was an extra.

 

Izuku Midoriya was supposed to be the weakest extra. He was supposed to be a pebble on Katsuki's path to greatness.

 

But as Katsuki watched Izuku sit in the sandbox, happily watching the mechanical carbon-fiber bird hop around his knees, Katsuki felt a cold, unfamiliar sensation twist in his gut. It wasn't just jealousy. It was profound, existential intimidation.

 

Katsuki stomped over, the sand crunching beneath his sneakers. His palms were already popping with tiny, aggressive sparks.

 

"Hey, Deku," Katsuki snarled, using the nickname he had coined months ago—meaning 'useless'. "You think you're better than me now because you can make some stupid toy?"

 

Izuku looked up, his expression entirely devoid of fear. There was only a calm, analytical curiosity in his green eyes. "No, Kacchan. I just fixed it."

 

"I'll break it again!" Katsuki yelled, lunging forward, throwing a right hook laced with a miniature explosion aimed directly at the mechanical bird.

 

Izuku didn't flinch. He didn't cower. His eyes narrowed, glowing with that same crackling emerald light. He slapped his hand flat against the sand.

 

Instantly, the silica in the sand violently rearranged itself. A wall of pure, tempered, impact-resistant glass erupted from the ground between them in a flash of green lightning.

 

BOOM.

 

Katsuki’s explosion slammed into the glass. The concussive force echoed across the park, blowing sand in every direction. But the glass didn't shatter. It didn't even crack. It absorbed the heat and the kinetic energy perfectly.

 

Katsuki stumbled back, his arm numb from the recoil. He stared at the smooth, flawless wall of glass, and then at Izuku, who was peering at him through it. Izuku looked slightly pale, and a single drop of blood leaked from his nostril, but he wiped it away with the back of his sleeve, unfazed.

 

"The melting point of silicon dioxide is around 1,710 degrees Celsius, Kacchan," Izuku said, his voice quiet but carrying a weight that felt far too old for a four-year-old. "Your explosions are primarily nitroglycerin-based. Unless you can generate a continuous, concentrated blast to sustain that heat, you can't break this."

 

Katsuki’s crimson eyes widened. The arrogant sneer slipped from his face, replaced by a look of wide-eyed shock. He wasn't looking at a pebble anymore. He was looking at a mountain. He was looking at a boy who could effortlessly counter his ultimate power with a pile of dirt and a thought.

 

From that day forward, the bullying ceased entirely.

 

Katsuki never pushed Izuku into the dirt. He never called him a weakling. How could he? It would be a delusion, and Katsuki Bakugo did not tolerate weakness in himself, nor did he tolerate lying to himself. Instead, the dynamic warped into a fierce, paranoid rivalry. Katsuki realized that if he wanted to be the Number One Hero, he didn't just have to be strong. He had to be stronger than a boy who could build miracles out of thin air. Katsuki trained harder, pushed his Quirk further, and studied relentlessly, driven by the terrifying shadow of Izuku Midoriya's limitless potential.

 

And Izuku? Izuku went to work.

 

 

 

The next ten years were a crucible of the mind.

 

If Izuku’s Quirk was Genesis, then knowledge was the fuel for the forge. Dr. Tsubasa had warned them about the neural backlash, and Izuku learned his limits the hard way. When he was six, he tried to create a fully functioning shortwave radio out of a pile of scrap metal without fully understanding the intricacies of the electrical circuitry. Halfway through the creation, his brain felt like it had been dunked in boiling water. He collapsed in screaming agony, suffering a migraine that lasted for four days and a seizure that terrified Inko so badly she nearly forbade him from using his Quirk ever again.

 

But Izuku was possessed by a quiet, burning determination. He wanted to be a Hero. He wanted to save people with a smile, just like All Might. But All Might saved people with overwhelming physical power. Izuku would save people with overwhelming intellect.

 

To create safely, he needed to understand perfectly.

 

At seven years old, Izuku finished the entire high school curriculum for chemistry and physics.

At ten years old, he was reading college-level textbooks on metallurgy, quantum mechanics, and thermodynamics.

At twelve, he was diving into bio-engineering, cybernetics, and advanced materials science.

 

His bedroom in the Midoriya apartment slowly transformed from the typical room of an All Might fanboy into something resembling a mad scientist's laboratory. The All Might posters were still there, but they were half-covered by massive whiteboards scribbled densely with molecular structures, chemical equations, and architectural blueprints. Stacks of notebooks cluttered his desk. But these weren't standard "Hero Analysis for the Future" notebooks, detailing simple observations of Quirks.

 

They were Hero Integration & Counter-Mechanics Blueprints.

 

If Izuku watched Kamui Woods on the news, his notebook didn't just say 'He uses wood.' It read: 'Kamui Woods: Cellulose manipulation. High vulnerability to thermal attacks. Counter-measure: Synthesis of a rapid-expanding, endothermic cryogenic foam to freeze the moisture in the wood fibers, rendering them brittle.' He would then draw the exact molecular structure of the cryogenic foam and the blueprints for a pressurized gauntlet to deploy it.

 

He didn't just observe the world; he reverse-engineered it.

 

Inko did her best to mother a boy genius. She made sure he ate massive amounts of high-calorie, nutrient-dense foods to fuel his hyper-active brain. She bought him endless supplies of scrap metal, old electronics, and raw chemical compounds. She watched with a mix of immense pride and lingering fear as her son would sit in the center of his room, surrounded by junk, his eyes glowing emerald. He would raise his hands, and the junk would disassemble into glowing clouds of atoms before swirling together to form intricate drones, specialized combat batons, or chemical vials.

 

He was building an arsenal. He was building himself into a Hero.

 

Physical training became a necessity as well. Izuku realized early on that a weak body couldn't support a hyper-computer for a brain. The heavier and more complex the creation, the more his heart had to pump oxygen-rich blood to his prefrontal cortex. If his cardiovascular system was weak, he would pass out. So, he ran. He lifted weights. He conditioned his body with the same terrifying, analytical precision he applied to his studies, optimizing his diet and sleep schedule to absolute perfection.

 

By the time he entered his final year at Aldera Junior High, Izuku Midoriya was a fourteen-year-old enigma.

 

He was quiet, polite, and unassuming. He wore his uniform neatly and kept to himself. But there was an aura around him—a quiet, humming competence that made people unconsciously step out of his way in the hallways. The teachers were slightly intimidated by him; he often corrected their physics and chemistry equations on the board with polite, devastating accuracy.

 

And then there was Katsuki Bakugo.

 

They sat in the same classroom, two titans in a school of ordinary fish. The career counseling session was exactly the catalyst everyone expected.

 

"You're all third years now," the teacher announced, slapping a stack of papers on his podium. "It's time to start thinking about your futures. But who am I kidding? You all want to be Heroes!"

 

The class erupted in cheers, students showing off their minor Quirks. Katsuki sat in the back, his feet propped on his desk, a sneer on his face.

 

"Hey, teach," Katsuki drawled loudly, silencing the room. "Don't lump me in with these rejects. They'll be lucky to end up as sidekicks to some busted D-lister. I'm going to U.A. High School. I'm going to be the Number One, and I'm going to surpass even All Might."

 

The class muttered in awe. U.A. High was the most prestigious Hero academy in the country.

 

"Ah, yes, Bakugo," the teacher said, adjusting his glasses. "You're aiming for U.A. You certainly have the grades and the Quirk for it. But... it looks like Midoriya is applying for U.A. as well."

 

The silence that fell over the room was absolute. Nobody laughed. Nobody mocked Izuku. They all slowly turned to look at the green-haired boy sitting near the window. Izuku didn't look up from his notebook. He was casually spinning a pencil between his fingers.

 

Suddenly, the pencil stopped spinning. It dissolved into a flicker of green light and reformed instantly into a perfectly crafted, metallic fountain pen. Izuku uncapped it and continued writing an equation.

 

Katsuki didn't explode his desk. He didn't leap up and scream. Instead, a thick, suffocating tension radiated from him. He glared at the back of Izuku’s head, his crimson eyes burning with a mix of fury and intense anticipation.

 

"Don't think your scrap-metal brain is going to be faster than my blasts at the entrance exam, Deku," Katsuki said, his voice a low, dangerous rumble. "I'm going to crush you."

 

Izuku stopped writing. He turned his head slightly, his emerald eyes meeting Katsuki's crimson glare. There was no malice in Izuku’s face, only a calm, unwavering certainty.

 

"I look forward to seeing you try, Kacchan," Izuku replied evenly.

 

The air in the classroom felt heavy enough to choke on. The teacher hurriedly moved on to the next subject, eager to break the tension between the two prodigies.

 

 

 

That afternoon, the sky was a bruised purple, threatening rain. Izuku walked home along a quiet route, passing under a large, concrete overpass. His mind was elsewhere, deep in the theoretical weeds of optimizing carbon-nanotube tensile strength for a potential capture-net. He was muttering under his breath, a habit he had never quite shaken, mentally rearranging molecular lattices.

 

If I align the carbon atoms in a hexagonal mesh and reinforce the nodes with synthetic spider-silk proteins, the elasticity should allow for a 400% expansion without breaking...

 

A sudden, wet squelch broke his concentration.

 

Izuku stopped. The hairs on the back of his neck stood up. The air suddenly smelled like raw sewage and rotting garbage. He spun around, dropping his notebook.

 

Rising from the manhole cover behind him was a massive, shifting mountain of dark green, viscous sludge. Two bulbous, manic eyes rolled within the liquid mass, locking onto Izuku with predatory glee.

 

"A medium-sized meat suit," the Sludge Villain gurgled, his voice sounding like thick mud bubbling over a fire. "Perfect. I need to hide, and you'll do just fine, kid!"

 

Before Izuku could react, a massive tendril of sludge whipped forward, wrapping around his chest and hoisting him into the air. The villain lunged, forcing the foul-smelling liquid into Izuku’s mouth and nose.

 

Panic, primal and terrifying, spiked in Izuku’s chest. He couldn't breathe. The sludge was forcing its way down his throat, burning his lungs.

 

Hypoxia, his brain clinically registered, even as he thrashed. Oxygen deprivation. If my brain doesn't get oxygen, I can't think. If I can't think, I can't use Genesis. I have less than forty seconds before unconsciousness.

 

"Don't fight it, kid," the villain hissed, wrapping tighter around him. "It'll only hurt for about forty-five seconds. Then it'll all be over."

 

Izuku's hands clawed at the sludge, but his fingers slipped right through it. It was amorphous. A non-Newtonian fluid. Physical strikes wouldn't work. Katsuki could probably blast his way out of this with heat and concussive force, but Izuku’s power required material and focus.

 

His vision was already blurring at the edges. Black spots danced in his eyes.

 

Think! Izuku screamed at himself in the confines of his mind. Analyze! It's a liquid-based biological entity. High water content. To neutralize a liquid without structural resistance, I need to alter its state. Heat? No, boiling it would scald me alive. Cold. I need to freeze it.

 

His brain went into overdrive, fighting through the agonizing lack of oxygen.

 

Liquid nitrogen? No, synthesizing liquid nitrogen from ambient air requires immense compression and cooling machinery, too complex, takes too long. I need a rapid endothermic chemical reaction. Something I can synthesize from the immediate environment. Carbon, nitrogen, hydrogen, oxygen.

 

Izuku reached out with both hands, his palms open, facing the mass of the villain.

 

His eyes began to glow with a blinding, desperate emerald light.

 

Barium hydroxide octahydrate and dry ammonium thiocyanate, Izuku thought, the chemical formulas burning into his mind's eye like brands of fire. Mixing them creates a highly endothermic reaction that absorbs massive amounts of heat from the surrounding environment. It drops the temperature drastically.

 

The world slowed down. Izuku felt the familiar, agonizing spike of a migraine driving into his skull. Blood erupted from his nose, mixing with the foul sludge on his face. His nervous system was screaming in protest as he forced it to perform ultra-complex atomic synthesis while choking to death.

 

He pulled moisture from the air. He ripped carbon and nitrogen from the garbage littered under the overpass. He extracted trace minerals from the concrete beneath them.

 

Barium. Hydrogen. Oxygen. Nitrogen. Sulfur. Carbon.

 

The atoms danced in his vision, glowing neon green. He wove them together, forcing the molecular bonds to snap and reform in the exact quantities required.

 

GENESIS!

 

With a concussive shockwave of emerald light, a massive cloud of crystalline white powder materialized directly inside the main mass of the Sludge Villain, heavily concentrated around Izuku’s body.

 

Instantly, the endothermic reaction triggered.

 

The villain shrieked as the heat was violently sucked out of his liquid body. The temperature in the tunnel plummeted below freezing in less than a second. The sludge turned grey, then white, as ice crystals rapidly formed, locking the liquid structure into a solid, frozen block.

 

The pressure around Izuku's chest shattered as the sludge became brittle ice. He tore himself free, falling to the concrete floor, coughing violently. He vomited up mouthfuls of frozen sludge, gasping for air as if it were the sweetest nectar on earth.

 

Above him, the villain was frozen solid in a grotesque statue of agony, immobilized completely.

 

Izuku lay on his back, his chest heaving, his head throbbing with a migraine so severe he felt like his skull was splitting open. Both of his nostrils were bleeding heavily, and tears of pure strain leaked from his eyes.

 

I... I did it, he thought, the edges of his consciousness fraying. Endothermic reaction... success.

 

Suddenly, the manhole cover a few yards away exploded upward, clanging violently against the concrete roof of the overpass.

 

A shadow, immense and imposing, stepped out of the sewers.

 

"HAVE NO FEAR, CITIZEN!" a booming voice echoed, shaking the very dust from the concrete pillars. "FOR I AM HE—"

 

The voice cut off abruptly.

 

Izuku forced his heavy eyelids open. Standing before him, radiating an aura of absolute, unparalleled power, was the Number One Hero. All Might.

 

The massive blonde hero stood frozen, his trademark blinding smile locked on his face, but his bright blue eyes were wide with utter bewilderment. He looked at the Sludge Villain, who was flash-frozen into a giant block of dirty ice. He looked at the frost coating the concrete walls. And then he looked down at the fourteen-year-old boy lying on the ground, bleeding from his nose, surrounded by the fading sparks of emerald light.

 

"Well," All Might said, his booming voice dropping an octave in sheer confusion. "This... is a first."

 

Izuku’s inner fanboy, suppressed by years of rigorous scientific detachment, suddenly resurrected with violent force. "A-All Might!" he croaked, scrambling into a sitting position, ignoring the blinding pain in his head. "You're... you're All Might!"

 

In a flash of speed so fast Izuku's hyper-processing brain barely registered it as motion, All Might was kneeling beside him, a massive hand resting gently on Izuku’s shoulder.

 

"Easy there, young man," All Might said, his eyes scanning Izuku’s bleeding face with deep concern. "You're bleeding. Did this villain do this to you?"

 

"N-no," Izuku stammered, frantically wiping the blood from his face with his sleeve. "It's... it's a drawback of my Quirk. I'm fine. I just... I had to synthesize an endothermic chemical compound to lower his core temperature and induce a phase change from liquid to solid. It took a lot of processing power because I was hypoxic."

 

All Might stared at him for three long seconds. The hero’s smile twitched slightly. "I... see. You froze him. With... science?"

 

"With Genesis," Izuku corrected, his voice finding a bit of its usual quiet confidence. "I rearranged the atoms in the environment to create the necessary chemical reaction."

 

All Might stood up, looking at the frozen villain with newfound awe. "A creation Quirk capable of instantaneous, complex chemical synthesis mid-combat? And you executed it while being suffocated?" The hero looked back down at Izuku, a fiery intensity burning in his shadowed blue eyes. "Young man. What is your name?"

 

"Izuku. Izuku Midoriya."

 

All Might let out a booming laugh, placing his hands on his hips. "Well, Young Midoriya! You have done a spectacular job! You kept your head in a crisis, analyzed your opponent's weakness, and executed a flawless counter-attack without causing collateral damage to the surrounding infrastructure! You, my boy, have the makings of a true Pro!"

 

Izuku felt a warmth spread through his chest that had nothing to do with the freezing temperature of the tunnel. Hearing those words from his idol... it was everything he had ever worked for.

 

"I'll take this villain into custody!" All Might announced, producing two large, empty soda bottles from his pockets. With incredible precision and speed, he chopped the frozen sludge into manageable chunks and shoved them into the bottles, screwing the caps on tight. "Now, I must be off! The press is waiting, and justice never sleeps!"

 

"Wait!" Izuku called out, scrambling to his feet. He grabbed his dropped notebook. "Can I... can I get your autograph? And... I have so many questions about your muscle-fiber density and how your skeleton withstands the kinetic recoil of your Detroit Smash!"

 

All Might paused, chuckling. He grabbed the notebook, signing two massive pages with a flourish. "A curious mind! Good! Keep analyzing, Young Midoriya!"

 

All Might crouched down, the muscles in his immense legs coiling like industrial springs.

 

Izuku’s eyes widened. His Quirk, always active on a subconscious level, began to feed him data. He looked at All Might's left side. He saw beneath the hero's suit. He saw the way All Might favored his right leg, the way his breathing was slightly hitched, and...

 

Wait, Izuku thought, his breath catching. His biological structure... it's compromised. There's a massive localized weakness in his respiratory system and left torso. His kinetic output is dropping by the millisecond. He's... he's severely injured.

 

"Thanks for your help, citizen!" All Might boomed.

 

"All Might, wait! You shouldn't jump, your left lung is—"

 

BOOM.

 

All Might launched himself into the air, the shockwave shattering the remaining frost on the ground. But as he soared into the sky, the strain of the jump, combined with the time limit of his muscular form, finally took its toll.

 

Mid-air, All Might coughed, a spray of blood leaving his lips. His massive form began to rapidly deflate, surrounded by a cloud of thick steam. He lost his trajectory, plummeting toward the roof of a nearby commercial building.

 

"Oh no," Izuku gasped.

 

Without thinking, Izuku activated his Quirk. He didn't build anything complex. He just slapped his hands against his own sneakers. In a flash of green light, the soles of his shoes transformed into highly compressed, coiled kinetic-springs made of titanium alloy.

 

Izuku crouched, the springs compressing with a heavy creak. He aimed for the roof where All Might was falling.

 

He released.

 

The springs launched Izuku into the air with terrifying velocity. He soared over the city streets, the wind howling in his ears, and landed on the roof of the building with a heavy roll, the titanium springs absorbing the impact perfectly before he dissolved them back into ordinary rubber.

 

He looked up.

 

Sitting against the rooftop fencing, coughing up a terrifying amount of blood, was a skeletal, emaciated man in baggy clothes.

 

Izuku froze. His mind raced, processing the visual data, matching facial bone structure, hair color, and the residual energy signature.

 

"All... Might?" Izuku whispered.

 

The skeletal man wiped the blood from his mouth and sighed, looking at Izuku with sunken, tired eyes. "Well. This is certainly not how I wanted this to go."

 

For the next twenty minutes, Izuku sat on the roof, listening in stunned silence as All Might explained the truth. The horrific battle five years ago. The missing stomach. The destroyed respiratory system. The three-hour daily limit. The symbol of peace was crumbling from the inside out.

 

"I smile," All Might said softly, looking out over the city, "to hide the fear inside. The world needs a Symbol of Peace. Without one, society will fall into chaos. But... my time is running out."

 

Izuku felt a profound sense of sorrow, but also a burning, analytical urgency. "Your internal organs," Izuku said rapidly, his mind spinning. "If I had access to a high-end medical facility, a bio-printer, and raw stem cells, I could theoretically synthesize a matrix to patch the respiratory lining—no, the scar tissue is too deeply integrated. But maybe a cybernetic bypass..."

 

All Might chuckled weakly, raising a hand to stop him. "You truly are a genius, Young Midoriya. But the damage is done. It cannot be healed by conventional or even unconventional means. But... it can be passed on."

 

Izuku stopped muttering. "Passed on?"

 

All Might stood up, his skeletal frame silhouetted against the setting sun. He looked down at Izuku with a piercing, deeply serious gaze.

 

"My Quirk, Young Midoriya, is not a simple strength enhancement. It is a sacred torch, passed down from generation to generation. It is the crystallization of power, stockpiled by the courage of those who came before me. Its name is One For All."

 

Izuku’s breath hitched. A transferable Quirk? The implications... the bio-energy required to alter DNA on a transmittable level... it defied every law of physics he had ever studied.

 

"I have been searching for a successor," All Might continued, taking a step toward the boy. "I thought I needed someone with a powerful physical Quirk. But today, I saw a boy who possesses something far greater than raw strength. I saw a boy with an unbreakable spirit, an unmatched intellect, and the courage to act when even Pro Heroes might hesitate."

 

All Might extended his hand toward Izuku.

 

"Izuku Midoriya. You are worthy. I want you to inherit my power."

 

The world seemed to stop spinning. The wind died down. Izuku stared at All Might’s outstretched hand.

 

The offer was everything. It was the ultimate power. Combined with Genesis, he would be unstoppable. He could build massive, city-sized structures without fatiguing. He could process atomic data at the speed of light. He would be a god among men.

 

But as Izuku stared at that hand, his brain, the hyper-computer that defined his existence, played out the simulation.

 

One For All is a physical stockpiling Quirk, Izuku thought. It generates immense, volatile kinetic energy. Genesis requires absolute, delicate neural precision. If I introduce a massive, uncontrolled energy source into my nervous system... the bio-electricity would fry my synapses. The sensory input would increase exponentially. I wouldn't just see the atoms; I would feel every single electron moving in a ten-mile radius.

 

My brain would hemorrhage in less than a second. Or, worse... I would become so powerful that I wouldn't need to think anymore. I would just punch my way through every problem, like everyone else.

 

Izuku looked down at his own hands. They were scarred from burns, calloused from tools, and stained with the ink of a thousand blueprints. Every ounce of power he had, he had earned through blood, sweat, and excruciating migraines. He had built his power piece by piece, atom by atom.

 

Borrowing someone else’s raw strength felt... wrong. It felt like an insult to the forge in his mind.

 

Tears welled in Izuku’s eyes. He felt a profound, overwhelming gratitude to the man standing before him. He was honored beyond words. But he knew the truth of his own soul.

 

Izuku stood up. He didn't take All Might’s hand. Instead, he stepped back, and bowed deeply, his head dipping below his waist.

 

"All Might," Izuku said, his voice trembling with emotion, but ringing with absolute, unshakable conviction. "Thank you. From the bottom of my heart, thank you. You are my hero, and you always will be. But... I have to decline."

 

All Might’s eyes widened in genuine shock. His hand slowly lowered. "You... decline? My boy, do you understand what I am offering you?"

 

Izuku straightened up, wiping the tears from his eyes, a small, brilliant smile gracing his face.

 

"I do," Izuku said softly. "But my power... Genesis... it's not just a Quirk to me. It's a promise to myself. It's proof that I can understand this world, and that I can make it better. If I take your power, I'll be walking your path. I don't want to borrow greatness, All Might. I want to build it."

 

Izuku raised his hand. The air around his fingers shimmered, warping as light bent around the sudden, intense manipulation of gravity and matter. In a flash of green light, a perfect, intricate, miniature replica of U.A. High School materialized in his palm, rendered in flawless, glittering titanium.

 

"I'm going to reach the top," Izuku said, his green eyes burning with a fire that rivaled the setting sun. "And I'm going to do it with my own mind."

 

All Might stared at the boy. For a moment, the hero felt a pang of disappointment. But as he looked at the sheer, undeniable resolve in Izuku Midoriya's eyes, the disappointment washed away, replaced by an immense, staggering wave of respect.

 

All Might threw his head back and laughed—not his booming hero laugh, but a genuine, joyous sound that rattled his thin frame.

 

"A builder of your own destiny!" All Might smiled, wiping a tear of mirth from his sunken eye. "Very well, Izuku Midoriya! I rescind my offer. But hear me now! I will be watching you. I will be watching you forge your path, and I have no doubt... you will change this world."

 

Izuku smiled, his heart soaring higher than it ever had before.

 

The spark of Genesis had been ignited ten years ago. But today, on this rooftop, the forge was finally opened for business. U.A. High wasn't ready. Katsuki Bakugo wasn't ready. The world wasn't ready.

 

Izuku Midoriya was going to rewrite the blueprints of heroism.

 

The Dagobah Municipal Beach Park was a graveyard of broken things. For years, the ocean currents had deposited the city’s refuse onto the sand, while illegal dumpers had added rusted refrigerators, gutted cars, and twisted heaps of industrial scrap. To the ordinary citizen, it was a localized environmental disaster.

 

To Izuku Midoriya, it was a gymnasium, a laboratory, and an all-you-can-eat buffet of raw atoms.

 

The ten months leading up to the U.A. Entrance Exam could only be described as a crucible of self-inflicted agony. Izuku had refused All Might’s Quirk, choosing to rely on Genesis, but that didn’t mean he could ignore the fundamental lesson the Number One Hero had inadvertently taught him: the vessel must be strong enough to hold the power.

 

Every time Izuku restructured matter, his brain fired billions of electrical signals, burning massive amounts of calories and demanding exorbitant levels of oxygen from his blood. If his cardiovascular system was weak, if his muscles couldn't endure the sudden spikes in his heart rate, he would pass out. U.A. High didn’t accept students who fell into comas after throwing one punch.

 

So, Izuku went to work on the beach.

 

It was a cold November morning, six months before the exam. The sky was an iron gray, and the freezing wind whipped off the ocean. Izuku, wearing a thick gray tracksuit, was currently hauling a rusted, waterlogged washing machine across the sand via a heavy rope slung over his shoulder. His boots dug into the earth, his quads burning with lactic acid, sweat freezing to his forehead.

 

"Fifty-eight... fifty-nine... sixty!" Izuku grunted, dropping the rope.

 

He collapsed to his knees, his chest heaving, his breath pluming in the freezing air in thick white clouds. He took a moment to let his heart rate stabilize, checking the digital biomonitor strapped to his wrist—a device he had constructed himself to track his blood oxygen levels and core temperature.

 

Heart rate at 170 BPM, he thought, wiping sweat from his eyes. Oxygen saturation at 96%. Good. The physical vessel is primed. Now... for the cognitive strain.

 

Izuku stood up and walked over to the rusted washing machine. He didn’t just need to build muscle; he needed to streamline his Quirk. In the past, creating complex machinery required him to consciously map out every single atom and molecular bond. It was like typing code perfectly by hand without looking at the screen. He needed to create "macros"—preset mental blueprints that he could execute instantly, bypassing the agonizing step-by-step processing.

 

He closed his eyes and visualized the atomic structure of the washing machine: the oxidized iron, the brittle plastics, the copper wiring.

 

Target: Deconstruction and purification. Output: High-carbon steel ingots, purified copper spools.

 

He pressed his palms against the cold, rusted metal. His eyes snapped open, glowing with that terrifying, crackling emerald light.

 

Genesis.

 

The air pressure around him dropped sharply. A low, humming vibration shook the sand. The washing machine didn't explode; it dissolved. It broke down into a swirling vortex of glowing, microscopic particles. Izuku’s mind raced, identifying and separating the elements. He tossed the useless rust and degraded plastics into the air, turning them into harmless dust that blew away in the ocean breeze. He isolated the iron, infused it with trace amounts of carbon pulled from the surrounding debris, and forced the molecular lattice to align perfectly.

 

A sharp ache bloomed behind his left eye. A single drop of blood slipped from his nostril.

 

Hold the structure. Solidify.

 

The blinding green light faded. Sitting neatly on the sand where the washing machine had been were three perfectly uniform, shining ingots of high-carbon steel, and a neat spool of purified copper wire.

 

Izuku stumbled back, clutching his head, a wave of nausea washing over him. He pulled a high-calorie protein bar from his pocket, tore off the wrapper with his teeth, and devoured it in three bites. His brain was screaming for glucose.

 

"Time elapsed: four point two seconds," Izuku muttered, checking his watch. "Still too slow. In a combat scenario, four seconds is enough time to die three times over. I need to push it under one second for basic materials, and under three seconds for complex tactical gear."

 

He looked out over the massive mountains of trash spanning the beach.

 

"Again."

 

For ten months, this was his routine. Before school, he hauled trash to build his endurance. After school, he deconstructed the trash to train his cognitive speed, turning Dagobah beach into a vast, organized grid of purified, highly valuable raw materials. He studied college-level physics, quantum mechanics, and electrical engineering until his eyes bled. He designed blueprints for non-lethal suppression weapons, mobility gear, and defensive countermeasures.

 

By the time February arrived, Dagobah Municipal Beach Park was entirely spotless. The glittering ocean waves rolled onto pristine, white sand.

 

Standing on the seawall, looking out at the horizon, was a very different Izuku Midoriya. He was no longer the scrawny, trembling boy from middle school. His body was lean, heavily muscled, and corded with the dense, functional strength of a gymnast. His green eyes held a sharp, terrifyingly calm focus—the look of a supercomputer that was permanently online.

 

Tomorrow was the U.A. Entrance Exam.

 

Izuku clenched his fist. The air around his knuckles warped slightly as a layer of carbon-nanotube armor materialized perfectly over his skin in less than 0.3 seconds.

 

He was ready.

 

 

 

"Izuku! Eat your eggs! All of them!"

 

Inko Midoriya was in full mother-hen mode. The dining table was covered in a spread that looked like it was prepared for a family of six, not a single teenager. There were stacks of pancakes, a dozen fried eggs, massive bowls of rice, grilled fish, and three tall glasses of nutrient-dense protein shakes.

 

"I'm eating, Mom, I'm eating," Izuku chuckled, shoveling rice into his mouth with mechanical efficiency.

 

"Your brain burns so much, Izuku," Inko fretted, pacing around the kitchen. "Dr. Tsubasa said you need at least ten thousand calories on days you heavily use your Quirk! Did you pack the glucose gels? What about the iron supplements? Oh, what if you get one of those awful migraines during the test?"

 

"Mom, look at me," Izuku said softly, stopping his meal.

 

Inko paused, looking at her son. He looked so mature. The quiet confidence radiating from him was a far cry from the anxious child who used to cry at loud noises.

 

"I know my limits," Izuku said, giving her a reassuring smile. "I've mapped out exactly how much caloric energy my presets require. I won't do anything reckless. I promise."

 

Inko sighed, her shoulders dropping. She walked over and wrapped her arms around his neck, pressing a kiss to his curly green hair. "I know. You're brilliant. Just... come back to me in one piece, okay?"

 

"I will."

 

Thirty minutes later, Izuku stood before the towering, imposing gates of U.A. High School. The sheer scale of the architecture was magnificent, a testament to modern engineering. But as Izuku looked at the massive glass panes and steel beams, his brain couldn't help but automatically calculate the load-bearing stress of the foundations. He shook his head, manually shutting down the analysis. He needed to save his energy.

 

"Out of my way, Deku."

 

Izuku didn't flinch. He turned to see Katsuki Bakugo striding up the walkway, his hands shoved deep into his pockets, his crimson eyes glaring daggers at the school building. Katsuki looked incredibly fit, his jawline sharp, his posture screaming aggressive dominance.

 

"Morning, Kacchan," Izuku said politely.

 

Katsuki stopped, turning his head to look at Izuku. The rivalry between them had only intensified over the last year. They hadn't fought since they were children, mostly because Katsuki refused to pick a fight he wasn't one hundred percent sure he could decisively win. Katsuki knew exactly what Izuku had been doing at the beach. He knew that the 'useless nerd' was now a terrifyingly optimized machine.

 

"You look like you're about to fall asleep standing up," Katsuki sneered, noting Izuku’s heavy eyelids—a side effect of processing a massive breakfast into usable glycogen.

 

"Just conserving processing power," Izuku replied evenly. "I'm sure you've refined your nitroglycerin sweat glands. Your forearms look slightly more hypertrophied to handle increased recoil."

 

Katsuki scowled, hating how Izuku could read his physical development like an open book. "Don't analyze me, you freak. Keep your eyes on your own damn score. Because I'm getting first place. I'm going to blow every single robot in that arena to ash."

 

"Good luck, Kacchan."

 

Katsuki clicked his tongue and stomped past him, radiating heat and irritation.

 

Izuku exhaled and took a step forward. As he did, a girl with short, gravity-defying brown hair tripped over a slightly uneven paving stone. She gasped, flailing her arms as she pitched forward toward the hard concrete.

 

Izuku’s eyes flicked toward her.

 

Target velocity: 4 meters per second. Distance to ground: 0.8 meters. Intervention required.

 

Izuku didn't jump to catch her. Instead, his eyes flashed emerald. He altered the kinetic friction coefficient of the air directly beneath her chest, creating a localized, invisible cushion of highly compressed nitrogen.

 

The girl bounced slightly on the invisible air-pillow, hovering an inch above the concrete, before Izuku gently released the pressure, allowing her feet to touch down softly.

 

She blinked, totally bewildered, patting her chest. "Whoa! What was that? Did I use my Quirk on accident?" She turned and saw Izuku standing there, his hands in the pockets of his U.A. tracksuit.

 

"Sorry," Izuku said, offering a small smile. "I compressed the air under you. Falling on your face before the exam is bad luck, right?"

 

The girl’s face lit up with a bright, sunny smile. "Whoa! That's such a cool Quirk! Air manipulation? Oh, I'm Ochaco Uraraka, by the way! It's so nice to meet you!"

 

"Izuku Midoriya. And it's... sort of air manipulation. Molecular restructuring, technically. Good luck in there, Uraraka-san."

 

Before she could ask any more questions, Izuku bowed politely and walked into the building. He needed to find his seat.

 

 

 

The auditorium was massive, packed with thousands of hopeful applicants. Izuku sat in the middle rows, his eyes closed, lightly tapping a rhythm on his knee to keep his mind grounded. Present Mic, the Voice Hero, was currently on stage, loudly explaining the rules of the practical exam.

 

"There are three main types of villains in every battle center!" Present Mic shouted, striking a dramatic pose. "You earn points based on their difficulty! Your goal is to use your Quirks to earn a high score by taking down these faux villains!"

 

Izuku had already solved the written exam in fifteen minutes. It was trivial. Now, he was rapidly cycling through his mental blueprints.

 

Robotics. Standard combat models. Likely reinforced steel chassis, optical sensors, lithium-ion battery cores. To maximize point yield with minimal caloric expenditure, I need wide-area neutralization without total destruction.

 

"Excuse me!" a booming, authoritative voice rang out.

 

Izuku opened his eyes. A tall, broad-shouldered student with glasses and perfectly combed hair was standing up, pointing a rigid finger at Present Mic.

 

"On the printout, there are four types of villains! If this is a misprint, then U.A., the top hero academy in Japan, should be ashamed of that foolish mistake!" The boy then whipped around, his arm chopping through the air to point directly at Izuku. "And you! With the curly hair! You've been tapping your knee and whispering under your breath this entire time! It's distracting! If you are here on a pleasure trip, then you should leave immediately!"

 

The auditorium went silent. Several students snickered.

 

Izuku didn't shrink into his seat. He calmly stopped tapping his knee. He looked at the tall boy, his green eyes glowing faintly in the dim lighting of the auditorium.

 

"I apologize if the tapping distracted you," Izuku said, his voice quiet but carrying perfectly across the silent room. "I was calculating the most efficient EMP frequency to shut down standard unshielded circuitry, based on the assumption that U.A. wouldn't waste millions of yen on military-grade faraday cages for expendable exam targets. As for the fourth villain, based on conventional game-theory utilized in entrance exams, it is statistically an obstacle. A zero-point trap designed to test our situational awareness and avoidance, not our combat capabilities. Sir."

 

The tall boy with glasses froze. His jaw dropped slightly. He slowly lowered his arm, utterly dismantled by the sheer, cold logic of Izuku's statement.

 

Present Mic blinked behind his orange shades, clearing his throat awkwardly. "Uh... YEAH! What the green kid said! The fourth villain is worth zero points! It's an obstacle! AVOID IT! Now, let's get to the practical!"

 

Katsuki, sitting a few rows ahead of Izuku, let out a low, dark chuckle. Stupid extra, Katsuki thought. Don't try to out-think the freak. You'll just embarrass yourself.

 

 

 

Battle Center B was a massive, sprawling replica of a modern city district. Tall concrete buildings, paved streets, and traffic lights created a perfect urban combat environment.

 

Izuku stood near the front of the massive steel doors, surrounded by dozens of other applicants. Most of them were wearing specialized gear—knee pads, utility belts, custom boots. Izuku was wearing a plain dark green tracksuit and standard red running shoes. He looked completely unequipped for a war zone.

 

"Hey, look at that guy," a boy with spiky hair whispered nearby. "No gear? What's his Quirk, growing grass?"

 

Izuku ignored them. He was taking deep, measured breaths, flooding his bloodstream with oxygen. He cracked his knuckles. He could feel the familiar, thrilling hum of the universe waiting to be shaped.

 

"RIGHT, LET'S START!" Present Mic's voice blasted over the speakers. "THERE ARE NO COUNTDOWNS IN REAL BATTLES! RUN, RUN, RUN!"

 

The massive steel doors began to slowly grind open.

 

Before the doors had even opened a full foot, Izuku moved.

 

He didn't wait for the gap to widen. His eyes flared a brilliant, blinding emerald. He slapped his hands against his thighs. In less than a microsecond, the fabric of his tracksuit pants rearranged itself at the molecular level, synthesizing with the carbon in the air to form an ultra-thin, hyper-flexible exoskeleton of carbon-nanotubes extending down to his boots.

 

He kicked off the ground, the sound barrier cracking like a whip.

 

The other applicants barely registered a blur of green light tearing through the small gap in the doors before a shockwave of wind blew them backward.

 

"What the...?" the spiky-haired boy gasped.

 

Izuku hit the main street of the artificial city going nearly sixty miles an hour. His brain was already operating at 400% capacity. He rounded the first corner and came face to face with three massive robots—two 1-Pointers and a 2-Pointer. They raised their mechanical arms, targeting lasers locking onto him.

 

"Target acquired," a robotic voice droned.

 

Blueprint: Explosively Pumped Flux Compression Generator, Izuku thought, his mind pulling up a complex 3D schematic of an EMP device.

 

He didn't stop running. He reached out his hands into the empty air. Green lightning cascaded from his palms. He pulled copper from the surrounding power lines, iron from the streetlamps, and synthesized high-explosive C-4 utilizing ambient carbon, nitrogen, and hydrogen.

 

In a fraction of a second, a metallic cylinder roughly the size of a soda can materialized in his right hand.

 

Izuku threw it like a baseball perfectly between the three robots.

 

"Detonate."

 

A sharp CRACK echoed through the street, but there was no fiery explosion. Instead, a blinding, invisible wave of electromagnetic energy pulsed outward in a ten-meter radius. The three robots immediately convulsed, their optical sensors shorting out with a shower of sparks, and they crashed to the concrete, entirely dead.

 

Four points, Izuku calculated, not even breaking his stride. Time elapsed: 2.1 seconds. Caloric burn: minor.

 

He vaulted over the fallen chassis of the 2-Pointer, using his reinforced exoskeleton to leap fifteen feet into the air, landing perfectly on the roof of a three-story building. From this vantage point, he had a tactical view of Sector B. He could see dozens of robots rolling through the streets.

 

He needed a ranged option. EMP grenades required too much physical throwing time. He needed something instantaneous. Something devastating.

 

Blueprint: Portable Electro-Magnetic Mass Accelerator. Railguns.

 

Izuku held his arms out, his fists clenched. This was a complex macro. The headache instantly spiked, a sharp needle of pain driving behind his eyes, and a thin trickle of blood began to leak from his nose.

 

Green light engulfed both of his forearms. He stripped massive amounts of raw titanium and copper from the infrastructure of the building beneath him, weaving the metals directly over his carbon-nanotube sleeves. Two heavy, sleek, dual-barreled gauntlets formed on his arms, humming with terrifying electrical potential.

 

To fire a railgun, he needed projectiles and electricity. He generated perfectly spherical, hyper-dense tungsten ball-bearings in his palms, feeding them into the chambers of the gauntlets. For power, he didn't use a battery. He used his own nervous system, amplifying his bio-electricity through Genesis, converting it into raw, high-voltage current.

 

He aimed his right arm down at a cluster of five 3-Pointers three streets over.

 

Lorentz Force activation.

 

THOOM.

 

The sound was deafening. A streak of blue lightning tore through the air, traveling at Mach 5. The tungsten projectile slammed into the center robot, the kinetic energy transferring so violently that the robot exploded in a massive fireball of shrapnel, taking the other four robots out in the collateral blast.

 

The recoil slammed Izuku backward, his boots skidding across the concrete roof. The titanium gauntlets hissed, venting extreme heat.

 

Nineteen points, Izuku smiled, wiping the blood from his upper lip. Let's rack it up.

 

For the next eight minutes, Sector B became the hunting ground of the Emerald Architect. Izuku was a phantom of destruction. He leaped from rooftop to rooftop. Wherever he aimed his arms, blue lightning flashed, and robots were reduced to molten scrap metal. When he encountered robots in close quarters, he didn't waste energy on railguns. He simply touched the street beneath them, synthesizing rapid-expanding polyurethane foam that hardened instantly, trapping the robots in immovable prisons.

 

He didn't just fight; he optimized. He saved a boy with a tail from a 2-Pointer by generating a high-tensile steel net from the air. He saved the girl from earlier, Uraraka, by creating a localized frictionless field under a charging 3-Pointer, causing it to slip and crash into a wall.

 

By minute eight, he had 85 points. He was exhausted. His head was throbbing with a brutal migraine, and his U.A. tracksuit was stained with sweat and the blood dripping from his nose. He dissolved the railgun gauntlets back into the atmosphere, panting heavily.

 

Caloric reserves dropping below 40%, he assessed, leaning against a concrete wall in an alleyway. I have enough points to pass safely. The tactical move is to cease Quirk usage and avoid further neural strain.

 

 

 

Deep within U.A. High, in the dark, monitor-lined observation room, the faculty of the school sat in stunned silence.

 

The screens were tracking hundreds of students, but nearly every Pro Hero in the room had their eyes glued to the monitors displaying Battle Center B, specifically the green-haired boy who was currently resting in an alleyway.

 

"Remarkable," Nezu, the principal of U.A., murmured, sipping a cup of tea. His beady black eyes gleamed with intense fascination. "Simply remarkable. The boy is generating high-yield military technology instantaneously. And he isn't pulling it from a pocket dimension or storing it in his fat cells like a standard Creation Quirk."

 

"He's manipulating the atomic structure of the environment," said Snipe, the sharpshooting hero, leaning closer to the screen. "Look at the footage from camera 4. When he built those railguns, the steel beams in the building he was standing on thinned out. He harvested the metal from the building itself to build the weapons, and powered them with his own bio-electricity. It's... it's terrifyingly efficient."

 

"It's reckless," a dry, exhausted voice countered. Shota Aizawa, known as Eraserhead, stood in the corner of the room, his dark eyes narrowed at the screen. "Look at him. He's bleeding from the nose. His hands are shaking. The cognitive processing required to perform molecular synthesis on that scale under combat stress is literally frying his brain. He's trading his neurological health for firepower."

 

"But he knows his limits!" a booming voice argued. All Might, in his ridiculously large muscle form, stood proudly behind Nezu, a massive grin on his face. He knew exactly who that boy was. "He's ceased operations. He's secured a top score, and now he is resting to prevent permanent damage. That is the tactical awareness of a veteran Pro!"

 

"Let's test that awareness," Nezu chuckled, raising a small white paw to a large red button on his console. "The true test of a hero is not how they fight when they have the advantage. It is how they react when they are outmatched, outgunned, and out of time. Let us introduce the unforeseen variable."

 

Nezu pressed the button.

 

 

 

Izuku was halfway through chewing a glucose tablet when the ground beneath his feet violently heaved.

 

It wasn't a localized tremor. The entire artificial city shook as if hit by a magnitude 8 earthquake. Windows shattered, and chunks of concrete rained down from the rooftops. Izuku stumbled out of the alleyway into the main street, his eyes widening in shock.

 

At the end of the avenue, the buildings were literally being torn apart.

 

Rising from the dust and debris, towering easily over two hundred feet tall, was a machine of apocalyptic proportions. It was a behemoth of slate-gray steel, its single, massive red optical sensor glowing with menacing intent. Its treads crushed entire streets, and one swing of its gargantuan arms demolished a four-story office building.

 

The Zero Pointer.

 

"Statistically an obstacle," Izuku muttered, his breath catching in his throat. "Right. Avoidance."

 

Panic erupted in the streets. The applicants, who had been bravely fighting the smaller robots moments before, broke rank and sprinted in the opposite direction, screaming in terror.

 

Izuku turned to run. He had 85 points. He was exhausted. Fighting this thing was illogical. It was suicide.

 

"Ow! Help! Please!"

 

Izuku froze. His blood ran cold.

 

He whipped his head around. About fifty meters away, directly in the path of the advancing Zero Pointer, was Ochaco Uraraka. She was trapped. A massive slab of concrete from a destroyed building had fallen, pinning her leg to the ground. She was desperately trying to use her gravity Quirk to lift it, but she was exhausted, her face pale, tears streaming down her cheeks.

 

The Zero Pointer raised its massive, hydraulic foot, preparing to crush the street—and her—into dust.

 

No one was stopping. The boy with the glasses was sprinting away. The boy with the spiky hair was gone.

 

Izuku didn't think. The analytical, cold supercomputer in his brain was instantly overridden by a primal, screaming mandate that had defined his soul since he was four years old.

 

Save her.

 

Izuku spun around, sprinting toward the titanic machine.

 

Analysis! his brain screamed, desperately trying to catch up with his heart. Target is over 200 feet tall. Armor plating is likely classified, highly reinforced depleted uranium alloy. A railgun won't pierce it. An EMP won't reach the shielded core. Kinetic impacts are useless.

 

He leaped over a pile of rubble, closing the distance to Uraraka.

 

To destroy a mass that large, I need to break the atomic bonds of its armor. I need absolute, overwhelming heat. I need plasma.

 

Plasma. The fourth state of matter. Creating it required stripping electrons from gas atoms, generating temperatures hotter than the surface of the sun, and containing it within a magnetic bottle so it didn't instantly vaporize the user.

 

Izuku had only ever theorized it. He had never attempted it. The computational requirement was astronomical.

 

If I do this... I might die, Izuku realized.

 

He planted his feet on the ground, placing himself directly between the pinned girl and the descending foot of the Zero Pointer. He looked up into the colossal red eye of the machine.

 

"Deku!" he heard Katsuki’s voice yell from somewhere in the distance.

 

Izuku raised both of his arms, aiming his open palms at the head of the colossal machine. He closed his eyes. He stopped holding back. He shattered the mental limiters he had placed on his Quirk, unleashing the absolute, terrifying potential of his mind.

 

"GENESIS: OVERRIDE!" Izuku screamed.

 

The world went white.

 

A hurricane of emerald energy erupted from Izuku’s body, so violent and intense that the asphalt beneath his feet disintegrated. The air itself began to scream as Izuku ripped hydrogen molecules from the humidity in the atmosphere, drawing them into a dense, swirling sphere hovering inches from his palms.

 

Blood exploded from both of his nostrils. Blood began to weep from the corners of his eyes, staining his face crimson. The migraine hit him like a physical blow from a sledgehammer, nearly shattering his consciousness. His entire body was convulsing, his muscles tearing under the sheer electrical load coursing through his nervous system.

 

Ionize the gas, his mind commanded, fighting through the agonizing pain. Generate the magnetic containment field. Super-conducting coils, bismuth strontium calcium copper oxide. Compress. COMPRESS!

 

In front of his hands, a sphere of blinding, violet-white energy materialized. It hummed with a sound that shook the fillings in the teeth of every student in a one-mile radius. It was a miniature star, held together by the sheer, desperate willpower of a fourteen-year-old boy's mind.

 

The heat radiating from the sphere instantly melted the debris around him into glass.

 

The Zero Pointer’s optical sensor flared red, recognizing a catastrophic energy spike. It tried to halt its descent, trying to pull back.

 

"Too late," Izuku choked out, blood pouring from his lips.

 

He broke the front of the magnetic containment field and pushed forward.

 

The release was apocalyptic.

 

A beam of pure, hyper-compressed plasma, screaming in violet and white, erupted from Izuku’s hands. It traveled upward at a fraction of the speed of light. It didn't just hit the Zero Pointer; it erased it. The beam punched directly through the depleted uranium armor of the machine’s chest, burning a hole thirty feet wide entirely through its chassis, before slicing upward and completely vaporizing its head.

 

The beam continued into the clouds, splitting the overcast sky, leaving a trail of ionized, glowing air in its wake.

 

For three seconds, there was absolute silence.

 

Then, the towering, headless chassis of the Zero Pointer swayed, groaningly slowly, before collapsing backward in a catastrophic explosion of fire, twisted metal, and shattered hydraulic fluid. The shockwave knocked every student off their feet, blowing a hurricane of dust across Sector B.

 

Izuku stood frozen for a moment, his arms still outstretched, smoking with residual heat.

 

His brain had entirely shut down. The world faded to a dark, static hum. His eyes rolled back into his head, and he collapsed backward, hitting the glass-covered asphalt like a puppet with its strings cut.

 

 

 

Silence reigned in the observation room.

 

Not a single hero spoke. Present Mic had dropped his microphone. Aizawa was gripping the edge of the console so hard his knuckles were white. Even All Might, who knew Izuku’s potential, was staring at the monitor with an expression of sheer, unadulterated awe.

 

On the screen, the clouds above Sector B were physically parted, revealing the blue sky above, courtesy of the plasma beam.

 

"He... he created a localized plasma cannon," Nezu whispered, his tea entirely forgotten. "He built a magnetic containment field and weaponized a star. He is fifteen years old."

 

"Look at him!" Aizawa snapped, pointing urgently at the screen.

 

The camera zoomed in on Izuku. He was lying motionless, his face covered in blood, his breathing horribly shallow. Uraraka had managed to free herself from the rubble in the confusion and was currently kneeling over him, crying hysterically.

 

"The physical toll..." Recovery Girl muttered, shaking her head. "His brain is exhausted. The bio-electrical feedback has put him into a comatose state."

 

"Send the medical drones immediately!" Nezu ordered, his voice sharp. He looked back at the screen, a profound, almost frightening smile crossing his rodent-like face. "Ladies and gentlemen. I believe we have just witnessed the birth of a God among heroes."

 

 

 

One week later.

 

Izuku stared at his bedroom ceiling.

 

He had spent three days in the U.A. infirmary. Recovery Girl had healed his torn muscles, but she couldn't heal cognitive exhaustion. She had given him strict orders to sleep, eat, and avoid using his Quirk for an entire week. He felt sluggish, his head still harboring a dull ache.

 

I went too far, Izuku thought, sighing. I didn't have a macro for the plasma cannon. I brute-forced the atomic structuring. I’m lucky I didn't suffer an aneurysm. But... Uraraka is safe.

 

"Izuku!" Inko’s voice shrilled from the hallway. "Izuku, it's here! The letter from U.A.!"

 

Izuku sat up quickly. He walked to his desk, grabbing the plain white envelope his mother had nervously slid under his door. He sat down at his desk, staring at it.

 

He tore it open.

 

A small metal disc fell out onto his desk. Instantly, a holographic projection flared to life.

 

"I AM HERE, AS A PROJECTION!" All Might’s booming voice echoed in the small bedroom.

 

Izuku smiled weakly.

 

"Young Midoriya!" the holographic All Might continued, pointing directly at the camera. "You passed the written exam with a flawless score! But that is to be expected of a mind like yours! The practical exam, however, is where you truly shone!"

 

The hologram shifted, showing a scoreboard.

 

"You acquired a staggering 85 Villain Points! A phenomenal display of combat efficiency and tactical Quirk usage!" All Might grinned proudly. "But, as you guessed, the Zero Pointer was not worth any points. So, why did you fight it?"

 

The video shifted, showing a clip of Izuku stepping in front of Uraraka, the green light erupting from his body, and the subsequent plasma blast.

 

"You fought it because a hero's true worth is not measured in points, but in lives saved! A hero course that rejects those who do the right thing is no hero course at all!"

 

The scoreboard updated. Next to Izuku's name, a new column appeared. Rescue Points.

 

"For your selfless, miraculous intervention, you have been awarded 60 Rescue Points! Giving you a grand total of 145 points! You have shattered the previous U.A. record!"

 

Izuku’s breath caught. Tears sprang to his eyes. He covered his mouth with his hand, overwhelmed.

 

All Might leaned forward, pointing a massive finger at Izuku. "You told me you would reach the top with your own mind, Young Midoriya. You have taken your first step. Welcome, Izuku Midoriya... to your Hero Academia."

 

The hologram clicked off.

 

Izuku sat in the silence of his room, the dull ache in his head entirely forgotten. He looked at his scarred, calloused hands. He closed his hands into fists.

 

The architect was in.

 

The U.A. High School uniform was a masterclass in mass-produced, durable textile engineering. As Izuku Midoriya stood in front of his full-length bedroom mirror, adjusting his red tie, his brain was already passively deconstructing the garments.

 

The blazer is a poly-wool blend, optimized for breathability but tightly woven enough to resist minor abrasions, he noted, smoothing down the lapels. The gold buttons are a cheap brass alloy, mostly zinc and copper. I could easily break them down to synthesize a localized electrical conductor if I’m ever caught without environmental metals.

 

He shook his head, physically forcing himself to stop the analysis.

 

"Stop it," he whispered to his reflection. "Save the processing power."

 

It had been a month since the entrance exam, and Izuku was still recalibrating. The plasma blast he had generated to destroy the Zero Pointer had been a terrifying revelation of his own upper limits. The resulting migraine had lasted nearly a week, and he had suffered mild optical nerve strain. He had sworn to himself—and to his weeping, frantic mother—that he would never attempt a free-form creation of that magnitude again without proper mental conditioning and preset blueprints.

 

Today was his first day at U.A. High School, the most prestigious hero academy on the planet. He needed his mind sharp, his macros primed, and his body ready for whatever absurd trials the faculty threw at him.

 

Walking to the campus, Izuku felt a strange sense of calm. For the past ten years, his intellect had isolated him. Middle school had been a wasteland of mediocrity where his peers thought small and Katsuki Bakugo thought loud. But here, behind the towering glass and steel of U.A., were the elite. The best of the best. He was finally stepping into a world where his mind could truly expand.

 

He navigated the labyrinthine hallways of the massive building until he found a door that looked like it belonged on a bank vault. Painted on the front in massive red letters was 1-A.

 

The door is excessively large, Izuku thought, his hand hovering over the handle. Accessibility for gigantification quirks or students with non-standard heteromorphic body types. Efficient.

 

He slid the heavy door open.

 

"Remove your feet from that desk immediately! It is a profound disrespect to our upperclassmen and the craftsmen who built it!"

 

The loud, mechanical voice belonged to the tall, glasses-wearing boy from the auditorium—the one who had tried to call Izuku out. He was currently making rigid, robotic chopping motions with his arms at none other than Katsuki Bakugo.

 

Katsuki was leaning back in his chair, his feet firmly planted on his desk, an arrogant, feral smirk on his face. "Huh? What middle school did you crawl out of, you extra? I'll put my feet wherever I want."

 

"I am Tenya Iida, from Somei Private Academy!" the boy declared, adjusting his glasses.

 

"Somei? So you're a stuck-up elite, huh? I'll have fun crushing you," Katsuki sneered. His crimson eyes flicked past Iida, landing on the doorway. The smirk vanished instantly, replaced by a deep, simmering scowl. "Deku."

 

The classroom went silent. Iida turned around, his eyes widening as he recognized Izuku.

 

"Ah! You're the boy from the auditorium!" Iida marched over, his posture ramrod straight. "I must apologize! I misjudged you completely. You realized there was a hidden rescue metric in the practical exam, didn't you? You saw through U.A.'s deception, while I ran away blindly. You are truly superior!"

 

"Oh, no, I didn't—" Izuku started, waving his hands defensively. "I didn't know about the rescue points. I just... saw someone who needed help."

 

"That makes it even more heroic!" a cheerful voice chimed in.

 

Izuku turned to see Ochaco Uraraka pushing her way through the doorway, her round face beaming with a bright smile. She bounded over to him, stopping just inches away. "You're the air-compression guy! Midoriya, right? Thank you so much for saving me! That laser beam you shot was insane! You completely obliterated that huge robot!"

 

"It wasn't a laser, it was super-heated plasma contained within a localized magnetic field," Izuku corrected automatically, rubbing the back of his neck, a slight blush dusting his cheeks. "But, uh, you're welcome. I'm glad you're okay."

 

"If you're just here to make friends, you can pack up your things and leave."

 

The voice was dry, flat, and seemed to suck the ambient energy right out of the room.

 

The three students froze and looked out into the hallway. Lying on the floor, encased entirely in a bright yellow sleeping bag, was a man. He looked like a giant, exhausted caterpillar. The man unzipped the sleeping bag and stood up, revealing a disheveled appearance, long tangled black hair, and a heavy capture-scarf coiled around his neck. He held up a pouch of jelly-drink and took a slow, depressing sip.

 

Visual analysis, Izuku’s brain fired off instantly. Disheveled appearance suggests nocturnal activity. The scarf is a specialized carbon-fiber and special-alloy wire weave, highly durable. The goggles around his neck are designed to conceal line of sight. Conclusion: Underground Pro Hero.

 

"It took you lot eight seconds to quiet down," the man sighed, stepping into the classroom. "Time is a limited resource. You kids aren't rational enough. I'm Shota Aizawa, your homeroom teacher."

 

The class blinked in collective shock. This homeless-looking man was a teacher at U.A.?

 

"Right, let's get to it," Aizawa said, pulling a dark blue uniform out of his sleeping bag. "Put these P.E. clothes on and head out to the training field."

 

 

 

The sun was bright and unforgiving on the massive dirt field behind the main campus. Class 1-A stood in a loose cluster, wearing their blue and white U.A. gym uniforms.

 

"A Quirk Apprehension Test?!" the class shouted in unison.

 

"What about the entrance ceremony? Or orientation?" Uraraka asked, looking deeply concerned.

 

Aizawa stood with his back to them, looking out over the field. "If you're going to become a hero, you don't have time for leisurely events. U.A.'s selling point is how unrestricted its traditions are. That also applies to how the teachers run their classes. You've been doing these tests since junior high, right? Pitching, long jump, fifty-meter dash... but you were never allowed to use your Quirks. It's irrational."

 

Aizawa turned, his dark, bloodshot eyes locking onto Katsuki. "Bakugo. You finished first in the practical exam. What was your best softball pitch in junior high?"

 

"Sixty-seven meters," Katsuki grunted, his hands in his pockets.

 

"Try doing it with your Quirk." Aizawa tossed a baseball to him. "Stay in the circle. Anything goes, just don't leave the ring."

 

Katsuki stepped into the chalk circle, rolling his shoulders. A vicious grin spread across his face. He wound his arm back, the air around his palm already beginning to distort with heat.

 

"DIE!" Katsuki roared.

 

BOOM.

 

A massive explosion of orange flame and black smoke erupted from his palm as he hurled the ball. The concussive shockwave rippled across the field, blowing the hair back from the observing students' faces. The ball rocketed into the sky, leaving a trail of smoke, until it was a speck in the clouds.

 

He detonated the nitroglycerin precisely at the apex of his swing, Izuku noted, his eyes tracking the trajectory. He focused the blast entirely behind the ball to maximize kinetic transfer without destroying the object. His control has improved exponentially.

 

Aizawa held up a small digital device. It beeped. He turned the screen toward the class.

 

705.2 meters.

 

"Whoa! 705 meters? That's insane!" a boy with electric-blonde hair yelled.

"This looks like so much fun!" a girl with pink skin and horns cheered.

"We can use our Quirks as much as we want! This is what the hero course is all about!"

 

Aizawa's expression darkened. The temperature on the field seemed to drop ten degrees.

 

"Fun?" Aizawa repeated, his voice dangerously low. "You have three years to become heroes. Are you going to have an attitude like that the whole time? Alright. Let's make a new rule. Whoever comes in last place in all eight tests will be judged to have no potential, and will be punished with expulsion."

 

The class erupted in panic. "Expulsion?! On the first day?!"

 

"We're free to do what we want with our students," Aizawa said, a terrifying, predatory smile pulling at the corners of his mouth. "Welcome to U.A.'s hero course."

 

Izuku didn't panic. He looked at Aizawa.

 

He's lying, Izuku deduced immediately. Or at least, he's manipulating the variables. He's an underground hero; he operates on efficiency and psychological warfare. He's creating an artificial pressure-cooker environment to force us to break our mental limiters and display our true survival instincts. Fascinating. But... if I treat this like a game, I'll fail. I have to treat this with absolute, lethal seriousness.

 

Izuku took a deep breath. He closed his eyes and began sorting through his mental blueprints. It was time to show U.A. what the absolute forge looked like.

 

 

 

Test 1: 50-Meter Dash

 

The electronic track was set up. Students were paired off. Izuku watched as Tenya Iida blasted down the track using the engines in his calves, clocking in at an incredible 3.04 seconds. A girl with frog-like features, Tsuyu Asui, cleared it in 5.58 seconds using incredible leg strength.

 

"Midoriya and Bakugo," Aizawa called out. "You're up."

 

The air on the field grew heavy. Katsuki stepped up to the starting line, his hands already sparking aggressively. He glared at Izuku, who was calmly walking to the line next to him.

 

"Don't hold back, Deku," Katsuki hissed, crouching into a sprinter's stance. "If you try to play it safe, I'll blow you off the track."

 

"I'm not going to hold back, Kacchan," Izuku replied evenly.

 

Izuku stood at the starting line. He didn't crouch. He stood perfectly straight, extending his right leg slightly. He closed his eyes.

 

Genesis.

 

The class gasped as a brilliant, blinding emerald light engulfed Izuku from the waist down. The sound of rapidly warping matter—a high-pitched electronic shriek mixed with the crunch of grinding metal—echoed across the field.

 

In exactly 0.8 seconds, the light faded.

 

Izuku’s legs were no longer visible. From the mid-thigh down, he was encased in a pair of sleek, hyper-aerodynamic, gunmetal-gray mechanical boots. They looked like something off a futuristic fighter jet. They were reinforced with carbon-fiber paneling, and at the back of each calf were two large, conical thruster vents.

 

Blueprint active: Cold-Gas Micro-Thruster Exoskeleton, Izuku mentally verified. Ambient nitrogen and oxygen compressed to 10,000 PSI within synthesized titanium-alloy chambers. No combustion, purely kinetic expansion. Safer than fire, faster than muscle.

 

"What the hell is that?" the electric-blonde boy gaped.

 

Katsuki’s eye twitched. "You think some shiny boots are going to beat me?"

 

"On your marks," the robotic voice of the starting machine chimed.

 

Izuku bent his knees slightly. He braced his core, ensuring his spine could handle the G-force.

 

"Get set."

 

"GO!"

 

Katsuki threw his hands backward, unleashing a massive dual-explosion that launched him forward like a missile. "EXPLOSIVE SPEED!" he roared, tearing down the track.

 

Izuku didn't move a muscle. He simply opened the titanium valves in his mind.

 

FWOOSH.

 

A deafening roar of hyper-compressed air blasted from the vents on Izuku's calves. He didn't run. The thrust was so violently powerful that it propelled him forward in a perfectly straight, frictionless glide, hovering an inch above the track. He broke the sound barrier halfway down the lane, a small sonic boom echoing across the field.

 

He crossed the finish line in a blur of gray and green, his boots digging into the dirt at the end of the track to violently arrest his momentum, kicking up a massive cloud of dust.

 

"1.21 seconds!" the robotic voice announced for Izuku.

"4.13 seconds!" it announced for Bakugo.

 

Katsuki crossed the line, skidding to a halt. He stared at the scoreboard, his chest heaving, his eyes wide with disbelief. 1.21 seconds. It wasn't even a race. It was a slaughter.

 

Izuku tapped his thigh. The metal dissolved into green light, breaking down into ambient dust, and his legs returned to normal. He swayed slightly, a dull throb pulsing behind his temples, but he quickly categorized the pain and ignored it.

 

The class was in an uproar.

"1.21 seconds?! He beat Iida by miles!"

"He just materialized high-tech support gear out of thin air! What kind of Creation Quirk is that?"

 

Aizawa stood by the starting line, his eyes narrowed, writing something on his clipboard. He bypassed the physical limitations of his body entirely by synthesizing a propulsion system, Aizawa thought. Highly adaptable. But how long can his brain sustain that level of architectural processing?

 

Off to the side of the track, a tall girl with elegant features and long black hair tied in a spiky ponytail watched Izuku with wide, onyx eyes. Momo Yaoyorozu felt a cold knot of dread form in her stomach.

 

Her Quirk, Creation, allowed her to produce any non-living object from her exposed skin, provided she understood its molecular structure and had enough lipid cells (fat) in her body to convert into matter. She had been praised as a prodigy her entire life. She was a recommendation student.

 

But what she had just witnessed broke the laws of her own reality.

 

He didn't pull those boots from his body, Momo analyzed, her heart beating rapidly. There was no biological conversion. He used the ambient matter in the air and the ground to synthesize complex, pressurized machinery instantaneously. He didn't even need to expose his skin. The processing power... the spatial awareness required to do that without misaligning a single titanium molecule and causing a catastrophic pressure explosion... it's impossible. Who is he?

 

 

 

Test 2: Grip Strength

 

Izuku walked into the gymnasium with the rest of the class. He was handed a small electronic grip-strength meter.

 

He looked at the device. He could just squeeze it normally, but Aizawa was testing Quirk utility.

 

Izuku held the meter in his left hand. His right hand hovered over it. A quick flash of green light, and his right hand was encased in a thick, brutalist hydraulic gauntlet made of solid steel and industrial pistons.

 

He squeezed the meter.

 

CRUNCH.

 

The machine didn't just register a number; the reinforced plastic casing shattered entirely under the thousands of pounds of hydraulic pressure, the digital screen flashing ERROR - MAX LIMIT EXCEEDED before dying.

 

Izuku sighed, dissolving the gauntlet. "Sorry, Sensei. I broke it."

 

Aizawa just grunted, tossing the broken machine into a bin.

 

Izuku turned and noticed Momo Yaoyorozu standing a few feet away. She was holding her grip meter. From her bare forearm, a thick, beautifully crafted steel vice-grip was slowly emerging, sliding out of her skin with a soft, glowing light. She attached it to her hand and squeezed the meter, registering a highly respectable 400 kg.

 

Izuku’s eyes lit up with intense, analytical fascination. He completely forgot about his own test and walked straight over to her, his personal space boundaries momentarily evaporating.

 

"Whoa," Izuku breathed, his green eyes locked onto her arm.

 

Momo flinched, stepping back slightly, intimidated by his sudden proximity and the intense look in his eyes. "E-Excuse me?"

 

"Your Quirk," Izuku muttered rapidly, pulling a small, battered notebook and a pen from his pocket—where they had come from, Momo had no idea. "It's a localized biological matter-conversion, isn't it? You're using the lipid cells in your body as the base atomic fuel for creation. That's incredibly brilliant!"

 

Momo blinked, caught completely off guard. "You... you understand the mechanics of it?"

 

"Of course! It's hyper-efficient!" Izuku beamed, scribbling furiously in his notebook. "By using your own lipids, you bypass the need to constantly monitor atmospheric atomic availability. You have a guaranteed, pre-processed fuel source. The conversion rate of fat to energy to matter must be astronomical. You could theoretically create highly complex organic compounds, or even pharmaceuticals, with zero risk of environmental contamination! That's amazing!"

 

Momo stared at him. The knot of dread in her stomach slowly began to unravel, replaced by a strange, warm flutter of validation. She had been terrified of his power, but here he was, looking at her Quirk as if it were the most miraculous thing he had ever seen.

 

"Thank you," Momo said softly, a genuine smile touching her lips. "I am Momo Yaoyorozu. And you are Midoriya-san, correct? Your creation Quirk... it is unlike anything I have ever read about."

 

"Oh, it's called Genesis," Izuku smiled. "It's ambient manipulation. It has its drawbacks, though. If I don't pay attention, I end up frying my own synapses. We should compare molecular blueprints sometime! I've been trying to optimize the tensile strength of carbon-nanotubes without making them overly brittle, and I'd love your input."

 

Momo’s eyes sparkled. For the first time in her life, she had met someone who spoke her language. "I would be absolutely delighted, Midoriya-san. I have some theories on integrating spider-silk proteins into the carbon lattice that might resolve the brittleness."

 

"That's genius!" Izuku gasped.

 

"Midoriya. Yaoyorozu," Aizawa's dry voice cut through their nerd-out session. "Stop flirting and get to the sandbox. It's time for the standing long jump."

 

Both Izuku and Momo turned bright red, instantly stepping away from each other and power-walking toward the sandbox, pointedly ignoring the snickering of the rest of the class.

 

 

 

Test 5: The Ball Throw

 

They were back on the dirt field. The sun was beginning to set, casting long, dramatic shadows across the grounds.

 

Ochaco Uraraka had just stepped up to the plate. She touched the baseball, rendering it entirely weightless with her gravity Quirk, and tossed it into the air. It floated up, up, up, until it vanished from sight.

 

Aizawa held up his device. It read the infinity symbol.

 

"Infinity?!" the class screamed. "That's incredible!"

 

Izuku smiled, happy for her. But as he stepped into the chalk circle for his turn, the weight of the test finally settled on him. He had placed first or second in almost every physical test so far by synthesizing temporary gear. But the ball throw was different.

 

A railgun wouldn't work. The tungsten projectile of a railgun was meant to destroy targets. If he fired a standard baseball out of a railgun, the sudden, violent application of Lorentz force would instantly vaporize the leather and cork into plasma before it even left the barrel.

 

He needed to throw the ball, intact, as far as physically possible.

 

To achieve maximum distance, Izuku calculated, bouncing the ball in his hand, I must eliminate two primary variables: gravity and air resistance. Uraraka eliminated gravity by altering the mass properties of the object. I can't do that. I manipulate matter, not fundamental physics.

 

He closed his eyes. The headache from the rocket boots and the hydraulic press was starting to build into a steady, annoying throb. He ignored it.

 

If I can't change the physics of the world, I'll change the environment around the ball.

 

Izuku opened his eyes. They flared a brilliant, searing emerald.

 

He didn't just target his own body this time. He targeted the baseball in his hand. The air around him snapped with static electricity. The ground beneath his feet cracked as he drew silica, iron, and carbon up through his shoes, channeling it through his body and into his right hand.

 

First, he coated the baseball in an ultra-thin layer of synthetic aerogel—the lightest solid material on earth, providing perfect thermal and kinetic insulation.

 

Second, he synthesized a microscopic, highly pressurized electromagnetic core around the ball. He essentially built a localized, self-sustaining magnetic levitation field.

 

The ball in his hand began to hum, glowing with a soft blue light. It floated an inch off his palm, perfectly suspended in a miniature vacuum bubble that would violently repel air molecules, nullifying aerodynamic drag to absolute zero.

 

"What is he doing to the ball?" Uraraka whispered, watching the glowing orb.

 

"He's overthinking it, like always," Katsuki sneered, though his eyes were glued to Izuku's hand.

 

Izuku then focused on his own arm. He didn't build a thruster. He built a kinetic-spring brace, weaving hyper-elastic titanium coils around his bicep and forearm.

 

He wound his arm back. The coils clicked, locking into place, storing immense potential energy.

 

Izuku took a breath. He stepped forward.

 

"Release."

 

He threw his arm forward. The titanium coils snapped, transferring a massive, concussive wave of kinetic energy into his hand.

 

But the ball didn't leave his fingers.

 

SMACK.

 

A thick, gray cloth wrapped entirely around Izuku’s right arm, binding it tightly to his torso. The glowing light in the baseball instantly vanished, the magnetic core dissipating. The titanium brace on his arm dissolved into dust. The baseball dropped from his hand, rolling pathetically out of the chalk circle, stopping two feet away.

 

Izuku blinked, stunned. The emerald glow faded from his eyes. His Quirk was gone. He reached inward to that familiar, humming engine in his mind, but it was completely silent. It was as if a heavy iron door had been slammed shut on his brain.

 

He looked over his shoulder.

 

Aizawa was standing ten feet away, his capture scarf extended, wrapping Izuku's arm. Aizawa’s hair was floating wildly in the air, and his eyes were glowing a piercing, terrifying red.

 

"Eraserhead," Izuku breathed, his analytical mind instantly identifying the hero. "You can erase Quirks by looking at them."

 

"I was watching you," Aizawa said, his voice cold and devoid of any teacherly warmth. He yanked the scarf, pulling Izuku a step forward. "You've been putting on quite the show today, Midoriya. Rocket boots, hydraulic presses, magnetic levitation. You think you're very clever. You think your intellect makes you untouchable."

 

Izuku frowned, his heart beating faster. "I was just trying to maximize my score using my Quirk, as you instructed."

 

"And what happens when your brain gives out?" Aizawa challenged, his eyes boring into Izuku's soul. "I watched the entrance exam footage. You generated a plasma beam to destroy the Zero Pointer, and then you immediately fell into a coma. You traded your consciousness for a single, flashy attack."

 

"That was an extreme scenario—"

 

"Every scenario is extreme in the field!" Aizawa barked, stepping closer. "Villains don't give you time to pull out a notebook and calculate the molecular weight of titanium! You are relying entirely on complex synthetic structures. But your Quirk requires extreme cognitive load. I can see your hands shaking right now. I can see the blood vessel pulsing in your temple. You're exhausted, and it's only the first day."

 

The class watched in stunned silence. No one dared to move.

 

Aizawa released his Quirk. His hair fell flat, and the red glow vanished from his eyes. The scarf unraveled from Izuku's arm.

 

Instantly, the familiar hum of the universe rushed back into Izuku’s mind. But with it came the blunt, sharp reality of the headache he had been suppressing. Aizawa was right. He was exhausted.

 

"You have a god-tier Quirk, Midoriya," Aizawa said quietly, stepping back. "But a god-tier Quirk attached to a vulnerable, easily fatigued human brain is a liability. If a villain blindsides you, and you don't have the 0.5 seconds it takes to build a shield, you die. If you burn out your synapses mid-fight, you become a hostage. You cannot rely purely on your mind's forge. You have to learn how to fight, how to survive, without building a masterpiece every time."

 

Izuku stared at his own hands. The callouses. The slight tremor in his fingers.

 

The words cut deep, precisely because they were entirely, rationally correct. Izuku had spent his entire life building the perfect weapons, but he hadn't focused enough on the wielder. He had treated his body as a battery for his mind, rather than a weapon of its own.

 

He looked up at Aizawa. There was no anger in Izuku's eyes, only a profound, humbling realization. He bowed his head deeply.

 

"You're right, Sensei," Izuku said softly. "I've been relying on overwhelming force to compensate for my vulnerability. I understand."

 

Aizawa narrowed his eyes, slightly surprised by how quickly the boy internalized the criticism. Most prodigies fought back with ego. This kid just analyzed the feedback and accepted it.

 

"Good," Aizawa said, tossing Izuku another baseball. "Now, throw the ball. You have one attempt left. Show me what you can do when you don't overcomplicate things."

 

Izuku caught the ball. He stepped back into the circle.

 

He didn't build a magnetic core. He didn't build a titanium brace. He didn't coat the ball in aerogel.

 

He just looked at his own right arm. He needed raw, physical power. If he couldn't build a machine to throw the ball, he would upgrade the machine he was born with.

 

Target: Human muscular-skeletal system, Izuku thought, his eyes glowing a muted, focused green. Action: Localized cellular enhancement.

 

It was dangerous. He usually strictly avoided biological manipulation on himself, but this wasn't complex. He didn't alter his DNA. He simply drew ambient carbon and calcium from the ground, forcefully weaving it into the bone marrow of his right arm, hyper-densifying his radius and ulna. He then pulled pure oxygen into his bloodstream, forcefully saturating the muscle fibers in his bicep and tricep, temporarily inducing a state of hyper-hypertrophy.

 

His right arm bulged slightly, the veins popping against his skin, turning a dark, bruised purple as the muscles strained against their natural limits.

 

It hurt. It hurt like hell.

 

Izuku gritted his teeth, winding his arm back. He channeled every ounce of his naturally built strength, combined with the temporary, brutal densification of his arm.

 

He threw the ball with a primal, roaring grunt.

 

The sonic boom cracked through the air. The ball vanished into the twilight sky.

 

Izuku immediately dropped to one knee, clutching his right arm. The green light faded. The artificial density dissolved, leaving his muscles screaming in agony, feeling like they had been run over by a truck. He gasped for air, sweat pouring down his face.

 

Aizawa held up the device.

 

706.0 meters.

 

Izuku had beaten Katsuki Bakugo by exactly 0.8 meters.

 

Izuku looked up at Aizawa, a tired, pained smile on his face. "I didn't... build anything, Sensei. I just used what I had."

 

Aizawa stared at the bruised, panting boy. A tiny, almost imperceptible smirk tugged at the corner of the underground hero's mouth.

 

"Not bad, kid," Aizawa muttered.

 

"DEKU!"

 

The scream was absolute murder.

 

Izuku turned his head just in time to see Katsuki sprinting toward him, his palms crackling with massive, volatile explosions, his face twisted in pure, unadulterated rage. The fact that Izuku had beaten him without even using a fancy machine—that he had beaten him with raw physical power—shattered Katsuki’s fragile ego into a million jagged pieces.

 

"TELL ME HOW YOU DID THAT! WHAT KIND OF TRICK WAS THAT?!" Katsuki roared, leaping into the air, aiming a blast directly at Izuku's face.

 

Izuku was too tired to dodge. His right arm was dead. He braced for the impact.

 

Suddenly, Katsuki was yanked violently out of the air, slamming face-first into the dirt. Aizawa’s capture scarf was wrapped tightly around the explosive boy, and Aizawa’s eyes were glowing red once more.

 

"What the... this cloth is stiff!" Katsuki struggled, his explosions completely nullified.

 

"It's a carbon-fiber weave woven with metal wire woven from a special alloy," Aizawa said, clearly annoyed. "Stop making me use my Quirk over and over. I have dry eye."

 

The class sweatdropped. What a waste of a cool Quirk!

 

Aizawa released Katsuki, who stood up, glaring daggers at Izuku but smart enough not to attack again with the teacher watching.

 

"We're wasting time," Aizawa sighed, walking away. "Whoever is next, step up."

 

 

 

An hour later, the sun had fully set. The class stood exhausted in front of the holographic scoreboard Aizawa projected from his phone.

 

Izuku found his name at the very top.

1. Midoriya Izuku

2. Yaoyorozu Momo

3. Bakugo Katsuki

4. Iida Tenya

5. Todoroki Shoto

 

He had done it. He had placed first.

 

At the bottom of the list, Minoru Mineta, a small boy with purple grapes on his head, was weeping hysterically. "I'm expelled! My hero academia is over before it began!"

 

"Oh, by the way," Aizawa said smoothly, turning off the projection. "I was lying about the expulsion. It was a rational deception to draw out the upper limits of your Quirks."

 

The class froze in collective shock.

 

"WHAT?!" several students screamed.

 

"Of course it was a lie," Momo Yaoyorozu said, sighing gracefully. "If you consider the psychological tactics required to motivate a group of highly volatile teenagers, it was the most logical conclusion. I thought you all knew."

 

"I didn't know!" Mineta sobbed, clutching his chest.

 

"That was a little nerve-wracking, huh?" a boy with hardened, spiky red hair laughed, clapping Izuku on the shoulder. "I'm Eijiro Kirishima! Man, you were super manly today! That rocket-boot thing was so cool!"

 

"T-thanks, Kirishima-kun," Izuku smiled tiredly, his right arm in a sling he had quickly created from some ambient fabric.

 

"Alright, you're dismissed," Aizawa said, already zipping himself back into his sleeping bag. "Midoriya. Go see Recovery Girl about that arm. You tore a bicep."

 

"Yes, Sensei."

 

As the class dispersed, walking back toward the main building to change out of their gym clothes, Izuku found himself walking alone, nursing his injured arm. His head was throbbing, a deep, persistent ache that demanded sleep.

 

"Midoriya-san?"

 

Izuku turned. Momo Yaoyorozu was walking up beside him. Her posture was perfect, as always, but she looked slightly hesitant.

 

"Oh, Yaoyorozu-san. Great job today. Second place is amazing," Izuku said sincerely.

 

"Thank you. First place is quite the achievement as well," she replied, offering a polite smile. She walked in silence for a moment before looking at his arm. "Your Quirk... Genesis. It is incredibly powerful. But Aizawa-sensei was correct, wasn't he? The mental toll it takes on you is severe."

 

Izuku nodded, looking down at his shoes. "Yeah. He was right. I've spent so much time trying to be the perfect architect that I forgot I'm also the one who has to hold the tools. I need to get stronger. Not just smarter, but physically stronger."

 

Momo looked at him, her dark eyes softening. She had spent the entire day feeling profoundly intimidated by him. She had thought his Quirk made him a god, an untouchable genius who looked down on the rest of them. But seeing him now, bruised, tired, and humbly accepting his flaws... it made him human. It made him a peer.

 

"If you'd like," Momo said softly, "I could assist you with your studies. Not the physical ones, of course, but the cognitive load. If we share our blueprints and molecular structures, we might find ways to streamline our respective creations. Reducing the processing time could alleviate your neural strain."

 

Izuku stopped walking. He looked at her, his eyes widening.

 

He had always worked alone. His notebooks were his private sanctuary. No one had ever understood them. No one had ever offered to help him build.

 

"You... you want to share blueprints with me?" Izuku asked, his voice cracking slightly.

 

"Only if you think it would be beneficial," Momo smiled warmly. "I believe we could learn a great deal from each other, Midoriya-san."

 

A massive, genuine smile broke across Izuku’s face, entirely erasing the fatigue of the day.

 

"I'd love that, Yaoyorozu-san. I'd love that more than anything."

 

As they walked back into the imposing halls of U.A. High, discussing the finer points of atomic lattice structures and lipid conversion rates, Izuku felt something new. It wasn't the thrill of a new invention, or the rush of kinetic power.

 

It was the quiet, comforting realization that for the first time in his life, he wasn't building alone.
