What If Deku Was the First Quirkless Hero with 200 IQ

 

The human brain operates, on average, at a processing speed of roughly 60 bits per second for conscious thought. It filters out the irrelevant: the hum of fluorescent lights, the subtle shift in air pressure when a door opens, the precise angle of a classmate’s posture indicating boredom.

 

Izuku Midoriya did not have that luxury. His brain absorbed, processed, and categorized everything.

 

Sitting in the back row of Aldera Junior High, Izuku stared at his notebook. To his teachers, he was the quiet, Quirkless kid who scribbled endlessly. To Izuku, the world was a living, breathing equation waiting to be balanced. He tapped his pencil—three beats per second, keeping rhythm with the ticking of the wall clock—as he analyzed the boy sitting two rows ahead of him.

 

Takeshi. Quirk: Minor Telekinesis. He can pull objects toward him. Maximum weight limit observed: 1.5 kilograms. Maximum range: two meters. But he doesn't account for the friction of the surface the object rests on, nor the aerodynamic drag. If he were to manipulate the micro-vibrations in the air instead of the object itself, he could effectively double his pulling capacity by creating a localized vacuum.

 

Izuku sighed, his pencil scratching rapidly across the page, documenting the physics equations that Takeshi would never understand, let alone utilize.

 

"Since you're all third years, it's time for you to think seriously about your future," the teacher announced, standing at the front of the classroom with a stack of career aptitude forms. "I'll pass out these printouts for your desired career paths, but... you all want to be heroes, don't you?"

 

The classroom erupted. Hands shot into the air. Desks rattled as students showed off their Quirks—elongated fingers, localized water spouts, minor fire conjuration.

 

Inefficient, Izuku’s mind supplied instantly. Seventy percent of these Quirks possess severe biological drawbacks. Dehydration, caloric depletion, joint strain. Society treats Quirks like magic, completely ignoring the fundamental laws of thermodynamics.

 

"Hey, teach!" a loud, arrogant voice cut through the noise. "Don't lump me in with these background characters. I'm not going to be stuck at the bottom with the rest of these rejects."

 

Katsuki Bakugo leaned back in his chair, feet kicked up onto his desk.

 

Izuku didn't look up, but his mind automatically began processing Bakugo. Katsuki Bakugo. Quirk: Explosion. Sweat glands in his palms secrete a substance highly similar to nitroglycerin. Heart rate currently elevated, approximately ninety beats per minute, indicating excitement. Ambient room temperature is twenty-two degrees Celsius, meaning his sweat production is baseline. If he initiates a blast right now, the thermal output would be roughly 400 degrees Celsius with a concussive force of—

 

"You're applying to U.A. High, aren't you, Bakugo?" the teacher asked, reading from a clipboard.

 

The class gasped. U.A. was the pinnacle of hero education. The acceptance rate was an abysmal 0.2 percent.

 

"That's exactly why you guys are just extras!" Bakugo sneered, leaping onto his desk. Small, crackling explosions popped in his palms. "I aced the mock test! I'm the only one at this school who could possibly get into U.A. I'll surpass All Might and become the top hero!"

 

"Oh, right," the teacher said, adjusting his glasses. "Midoriya, you wanted to go to U.A. too, right?"

 

Silence dropped over the room like a lead weight. For exactly 1.4 seconds, no one moved. Then, the entire class burst into uproarious laughter.

 

"Midoriya? No way!"

"You can't get into the hero course just by studying!"

"He's Quirkless! What's he gonna do, calculate the villain to death?"

 

Izuku kept his eyes on his notebook. He felt the familiar sting in his chest, a purely emotional response that his logical mind hated. Statistically, they are correct, Izuku thought, his jaw tightening. No Quirkless individual has ever been accepted into the U.A. Hero Course. The entrance exam is biased toward physical destruction, heavily favoring emitter and transformation-type Quirks.

 

Suddenly, a hand slammed onto Izuku’s desk, accompanied by a sharp, localized detonation. The shockwave blew Izuku's notebook out of his hands, singeing the edges of the paper. Izuku didn't flinch. He mentally calculated the blast radius and noted that Bakugo had purposefully constrained the explosion to a non-lethal, intimidation-level yield.

 

"Listen up, Deku," Bakugo snarled, smoke wafting from his palms. "You're worse than the rest of these rejects. You're completely Quirkless. You really think you can rub shoulders with me?"

 

Izuku finally looked up. His green eyes were calm, analytical, and completely devoid of the fear Bakugo wanted to see. That was what always infuriated Bakugo the most. Izuku didn't look at him with terror; he looked at him like he was a specimen on a slide.

 

"The U.A. entrance guidelines were revised three years ago, Kacchan," Izuku said, his voice even, though his heart rate had spiked to 110 BPM. "There is no longer a rule prohibiting Quirkless applicants from taking the practical exam. It's just... unprecedented."

 

"Unprecedented?" Bakugo grabbed Izuku by the collar of his uniform, hauling him up. "I'll give you unprecedented! If you even think of applying, I'll turn you to ash before the exam even starts!"

 

Izuku stared at the hand gripping his shirt. If I pivot my left foot, apply pressure to his radial nerve with my right thumb, and shift my center of gravity, I can dislocate his grip and use his forward momentum to throw him into the desk behind him.

 

But Izuku didn't do it. Assaulting a student with a powerful Quirk would result in his own immediate expulsion and a permanent black mark on his record. The system was rigged. The Quirkless were always the aggressors in the eyes of the law, even in self-defense.

 

"Let go, Kacchan," Izuku said softly.

 

Bakugo scoffed, shoving Izuku back into his chair. "Don't forget your place, nerd."

 

When the final bell rang, Izuku remained in his seat, waiting for the room to clear. He meticulously packed his bag, carefully placing his singed Hero Analysis for the Future No. 13 inside. He had spent months analyzing the structural weaknesses of popular Support Gear, cross-referencing them with metallurgical data to design lighter, more efficient composites.

 

He walked out of the school, taking his usual route home. The afternoon sun was warm, but the shadows beneath the underpass were cool and damp. Izuku liked the underpass. The acoustics allowed him to hear approaching footsteps from sixty meters away.

 

Slap. Squelch. Drag.

 

Izuku stopped walking. His brain processed the sound instantly.

Footsteps? No. Too fluid. High viscosity. Heavy mass dragging against concrete. Volume indicates a large organism. The smell of raw sewage and methane.

 

Izuku spun around, dropping into a defensive stance.

 

Rising from the manhole behind him was a mountain of dark, undulating sludge. Two massive, bulbous eyes rolled in the gelatinous mass, fixing on Izuku.

 

"A medium-sized invisibility cloak," the sludge villain gurgled, a horrific, wet sound that reverberated off the concrete walls. "Perfect."

 

Izuku’s mind raced. Villain. Mutant/Transformation class. A living fluid. Physical strikes will be useless; kinetic energy will merely disperse through the liquid matrix. No solid organs visible except the eyes and teeth. Highly flammable given the methane odor, but I have no ignition source. Escape routes: forward is blocked by the entity, backward is thirty meters to the exit. I cannot outrun a fluid capable of rapid expansion.

 

Before Izuku could take a step, the villain lunged. A tendril of thick, suffocating mud wrapped around Izuku’s legs, sweeping him off his feet. He hit the concrete hard, the breath knocking out of his lungs. Instantly, the sludge surged over him, forcing its way up his nose and into his mouth.

 

"Don't worry," the villain whispered, the sound vibrating directly through the sludge into Izuku’s skull. "It'll only hurt for about forty-five seconds. Then, it'll all be over."

 

Suffocation, Izuku realized, his hands tearing frantically at the mud covering his face. His fingers sank into the slime, finding no purchase. He's displacing the oxygen in my lungs. I have approximately two minutes of consciousness before hypoxia sets in, but the panic response will burn through my oxygen reserves in less than forty seconds.

 

Izuku forced himself to stop thrashing. Conserve oxygen. Think.

 

He clawed at the villain's eyes—the only solid matter he could identify. The villain hissed, reeling back slightly, but it wasn't enough. Black spots danced in the corners of Izuku's vision. The pain in his chest was excruciating. His 200 IQ, his encyclopedic knowledge of physics and biology, his meticulously calculated plans for the future—none of it mattered. Biology was winning.

 

Is this it? Izuku thought, his vision narrowing to a pinpoint. Killed in an alleyway because I lacked the genetic mutation to produce fire or wind?

 

Suddenly, the manhole cover blew off with the force of a bomb, clattering violently against the ceiling of the underpass.

 

Izuku couldn't turn his head, but he felt the shift in air pressure. The temperature in the tunnel dropped by a fraction of a degree. A massive shadow eclipsed the ambient light of the tunnel opening.

 

"HAVE NO FEAR, YOU ARE SAFE," a booming, resonant voice echoed, possessing a decibel level that shook the dust from the concrete. "NOW THAT I AM HERE."

 

All Might, Izuku thought, his fading consciousness desperately trying to cling to the data. Height: 220 centimeters. Weight: 274 kilograms. The Number One Hero.

 

The sludge villain whipped around, screeching in terror. "TEXAS..." All Might pulled his fist back. The air around his arm seemed to warp, the kinetic energy so dense it created a localized pressure differential. "...SMASH!"

 

All Might threw the punch. He didn't even make contact with the villain. He didn't have to.

 

Izuku's brain registered the impossible physics of the attack. All Might’s fist compressed the air in front of it with such velocity and mass that it created a literal hurricane-force shockwave. The wind pressure hit the sludge villain like a freight train, atomizing the fluid and scattering it across the walls of the tunnel.

 

The wind pressure also hit Izuku. He felt the mud violently ripped from his lungs and airway before the sheer force of the gale knocked him completely unconscious.

 

 

 

"Hey! Wake up! Thought we lost you there!"

 

Light filtered into Izuku's eyes. He blinked, his pupils contracting to adjust to the brightness. Standing over him, casting a shadow that seemed to block out the sun, was All Might.

 

Izuku scrambled backward, his heart hammering against his ribs. Respiration normal. No lingering fluid in the lungs. Time elapsed: approximately three minutes based on the sun's position.

 

"Excellent! You're moving around fine!" All Might laughed, a hearty, booming sound. "Sorry about that! I didn't mean to get you caught up in my villain hunting. Usually, I catch them right away, but I'm in a new city and got a little careless!" He held up two large, plastic soda bottles. Inside, the sludge villain was compressed and swirling angrily.

 

Izuku stared at the bottles. Polyethylene terephthalate. Capable of holding roughly 100 PSI. If the villain expands rapidly, the structural integrity of the plastic will fail.

 

"Well, I must be going!" All Might said, tucking the bottles into the massive pockets of his cargo pants. "Take care of yourself, young man!"

 

"Wait," Izuku blurted out, scrambling to his feet. "Already? But... I have questions. I need to know..."

 

"A pro is constantly fighting time and enemies!" All Might said, crouching down. The concrete beneath his boots cracked under the immense pressure.

 

Izuku's mind raced. This was it. The singular variable in his life. The man who stood at the absolute pinnacle of a Quirk-dominated society. If anyone could understand, if anyone could validate his existence, it was All Might.

 

As All Might leaped into the air, the force of his jump creating a miniature crater, Izuku didn't think. He acted on pure, desperate impulse. He lunged forward, grabbing onto All Might's leg just as the hero broke the sound barrier.

 

The wind roared in Izuku's ears, deafening and brutal. The G-force pressed against his face, making it impossible to keep his eyes open.

 

"Hey, hey, hey!" All Might yelled, looking down in shock. "What are you doing? Let go! Your fanaticism is too much!"

 

"If I let go now... I'll fall to my death!" Izuku screamed over the rushing wind, his hands locked in a death grip around the fabric of All Might's pants. Altitude: roughly 400 meters. Terminal velocity would be reached in 12 seconds. Impact would result in instantaneous liquefaction of internal organs.

 

"Oh, right!" All Might realized. "Hold on tight and close your eyes!"

 

A moment later, they crashed down onto the roof of a towering office building. Izuku collapsed onto the hard roof, gasping for breath, his legs trembling violently.

 

"That was incredibly dangerous!" All Might scolded, walking toward the roof access door. "You should knock on the door, someone will let you down. Now, I really must be going—"

 

Suddenly, a violent spasm wracked All Might's massive frame. He stopped dead in his tracks. A horrible, wet coughing sound erupted from his chest. Smoke began to pour from his body, thick and obscuring.

 

Izuku, still catching his breath, watched in stunned silence. Thermodynamic anomaly. He's emitting vast quantities of steam. Is his Quirk failing? Is it a byproduct of exertion?

 

The smoke cleared, and where the hulking, invincible Symbol of Peace had stood, there was now a skeletal, emaciated man in baggy clothes. He wiped a trail of blood from his chin.

 

Izuku’s eyes widened. He didn't scream. He didn't panic. His brain immediately went to work.

 

Mass reduction of over 70 percent. Severe muscle atrophy. Posture indicates chronic pain, likely centered around the left abdomen. The coughing of blood indicates severe pulmonary or respiratory compromise. This isn't a transformation Quirk fading; this is his true form. The muscular form is the anomaly. A facade.

 

"You..." Izuku whispered, stepping forward. "You're... fake? An imposter?"

 

"I assure you, I am All Might," the skeletal man sighed, sliding down against the railing of the roof. He lifted his baggy shirt, revealing a horrific, jagged scar that covered the entire left side of his chest and abdomen. The skin was purple and sunken, looking like a crater carved out of his flesh.

 

Izuku stared at the wound. His encyclopedic knowledge of hero battles flipped through his mind like a rolodex.

 

"An injury I got from an enemy's attack five years ago," All Might said quietly, his voice lacking all the booming bravado from before. "Half my respiratory organs were destroyed, and I lost my whole stomach. I've become emaciated from repeated surgeries. Right now, I can only do hero work for about three hours a day."

 

Five years ago, Izuku calculated. Toxic Chainsaw? No, the structural damage of a chainsaw would leave laceration scarring, not a blunt-force crater with thermal necrosis. This was a concussive blast or a kinetic impact of unimaginable power. An enemy that the media never reported. A cover-up.

 

"Why are you showing me this?" Izuku asked, his voice steady.

 

All Might looked at him, surprised by the boy's analytical calmness. "Because you saw it. I'm trusting you to keep your mouth shut. The Symbol of Peace cannot be seen as weak. If the world knew I was like this, the deterrent against crime would crumble."

 

Izuku understood. It was sociology 101. The entire Japanese infrastructure of peace was balanced on the shoulders of one man’s perceived invulnerability. If that pillar fell, society would collapse into anarchy.

 

"I understand," Izuku said softly. He looked at his hands. "All Might... I have a question. A hypothesis, really, but I need your empirical data."

 

All Might blinked. "Uh... alright?"

 

Izuku looked up, his green eyes piercing. "Can a person without a Quirk become a hero like you? If someone possesses the intellect, the tactical superiority, and the willpower to compensate for the lack of a genetic mutation... can they stand on the same stage as those who were born with power?"

 

The wind howled across the rooftop. All Might looked at the boy. He saw the desperate hope in his eyes, but he also remembered the excruciating pain of his own injury. He remembered the villains who could tear buildings apart with a thought.

 

"No," All Might said bluntly.

 

Izuku felt something cold snap in his chest.

 

"Without power, how can you fight those who have it?" All Might continued, his voice heavy with grim reality. "Pro heroes are always risking their lives. Some villains simply cannot be beaten without a powerful Quirk. It's good to dream, young man, but you have to be realistic. If you want to help people, become a police officer. They get mocked, but it's fine work."

 

All Might stood up, walking toward the stairwell door. "It's not bad to dream. But make sure your dreams are attainable."

 

The door clicked shut, leaving Izuku alone on the roof.

 

For ten minutes, Izuku didn't move. He ran All Might’s words through his head. He subjected them to logical scrutiny. He tried to find a flaw in the Number One Hero's argument.

 

He is assessing 'power' purely through the lens of biology, Izuku thought, his hands clenching into fists. He equates a Quirk to capability. But humanity didn't conquer the planet because we had claws or thick hides. We conquered it because we mastered fire. Because we built weapons. Because we used our brains.

 

Izuku walked down the stairs of the building, his mind a whirlwind of conflicting emotions and raw, calculating logic. He was Quirkless. Society deemed him a liability. The Number One Hero told him to give up.

 

But Izuku’s brain refused to accept an unsolvable equation.

 

He wandered the streets of Musutafu, lost in thought. He didn't notice the crowds or the traffic until the sound of a massive explosion shook the ground beneath his feet.

 

Izuku snapped back to reality. Smoke was billowing into the sky a few blocks away. The smell of burning sulfur and... nitroglycerin.

 

Kacchan, Izuku realized.

 

His feet moved before he made a conscious decision, sprinting toward the source of the smoke. He rounded the corner into a commercial shopping district and froze.

 

The street was a war zone. Fires raged across storefronts. The sludge villain—the exact same one from the underpass—had grown to a massive size, absorbing the ambient fire and using it as a shield. And trapped inside the gelatinous mass, struggling violently, was Katsuki Bakugo.

 

Bakugo was firing off explosions in a blind panic, but every blast only fed the flames around them and allowed the sludge to spread further.

 

Pro heroes were on the scene, but they were doing absolutely nothing. Death Arms was shouting at the crowd to stay back. Kamui Woods was hesitating, his wooden body vulnerable to the intense heat. Mt. Lady was complaining that the two-lane street was too narrow for her giant form.

 

Izuku stood at the front of the crowd, his mind shifting into hyper-overdrive. Time seemed to slow to a crawl.

 

Analysis:

Villain escaped All Might's pockets, likely when I grabbed his leg. The impact loosened the bottle caps. My fault.

Hostage: Katsuki Bakugo. His explosions are creating an updraft, sucking oxygen from the surrounding area. He will asphyxiate in less than three minutes.

Pro Heroes on scene: Useless. They lack the specific Quirk match-ups to deal with a fluid, highly flammable enemy.

 

"We just have to wait for someone with a suitable Quirk!" Death Arms yelled to another hero.

 

Izuku felt a surge of cold, calculating fury. Wait? By the time a hero with a water or vacuum Quirk arrives, Katsuki’s brain will have suffered permanent hypoxic damage. They aren't thinking. They are blindly relying on their genetics instead of adapting to the situation.

 

Izuku looked around. His eyes locked onto a nearby convenience store that had its front windows blown out by the shockwave of Bakugo's explosions.

 

Problem: Giant fluid mass holding a hostage.

Solution: Chemical disruption of the fluid matrix to force a release.

 

Izuku didn't wait for a hero. He bolted past the police tape.

 

"Hey! Kid, stop! You'll get yourself killed!" Death Arms roared, reaching for him.

 

Izuku ducked under the hero's thick arm, his momentum carrying him straight through the shattered glass of the convenience store. The inside was a wreck, shelves toppled over. Izuku moved with terrifying precision.

 

Aisle 3: Cleaning supplies.

He grabbed a jug of industrial chlorine bleach (Sodium hypochlorite) and a bottle of high-strength toilet bowl cleaner (Hydrochloric acid).

Aisle 4: Hardware.

He grabbed a roll of duct tape and a heavy-duty glass mason jar.

Aisle 1: Toiletries.

Two cans of aerosol hairspray.

 

He hit the floor behind the checkout counter as a blast of fire washed over the store's entrance. His hands moved like lightning. He poured the bleach into the mason jar. He knew that mixing sodium hypochlorite with hydrochloric acid would yield chloramine vapor and pure chlorine gas—highly toxic, rapidly expanding, and severely irritating to mucous membranes.

 

But he needed delivery and ignition.

 

He taped the two aerosol cans to the side of the mason jar. He grabbed a cheap plastic lighter from the counter display and taped it so the gas valve was locked down, emitting a steady, tiny flame directly above the aerosol nozzles.

 

When the glass breaks, the acid and bleach mix. The expansion of chlorine gas will create a localized pressure bomb. If the aerosol cans rupture from the heat or impact, the propellant will ignite via the lighter flame, creating a flash-bang effect followed by a cloud of caustic gas. The sludge villain has eyes and a mouth; it respires. It will be forced to recoil from the chemical burn.

 

Total time spent inside the store: 14 seconds.

 

Izuku sprinted back out into the street. The sludge villain saw him coming.

 

"You again!" the villain roared, lifting a massive tendril of sludge to swat Izuku away.

 

Izuku didn't slow down. He analyzed the trajectory of the tendril. Speed: 40 km/h. Angle: 45 degrees. If I slide now...

 

Izuku dropped to his knees, sliding across the pavement, the sludge tendril sailing inches above his head. He popped back up, his arm rearing back.

 

"Deku?!" Bakugo choked out, his eyes wide with shock and rage. "What the hell are you doing?!"

 

"Rescuing you," Izuku said coldly.

 

He threw the rigged mason jar. He didn't aim for the villain's eyes. He aimed directly at the villain's gaping, jagged mouth.

 

The heavy glass jar sailed through the air in a perfect parabolic arc. It smashed perfectly against the villain's exposed teeth.

 

The reaction was instantaneous. The glass shattered, mixing the acid and bleach. The aerosol cans ruptured upon impact. The lighter ignited the propellant.

 

BOOM.

 

A blinding flash of light and a concussive shockwave ripped through the street. But it wasn't a normal explosion. It was immediately followed by a thick, sickly-yellow cloud of rapidly expanding chlorine gas directly inside the villain's center of mass.

 

The villain shrieked—a horrific, bubbling scream. The chlorine gas immediately began burning its exposed mucous membranes. The fluid matrix of its body convulsed uncontrollably as the chemical reaction altered its pH balance, breaking down its viscosity.

 

"ARGH! MY EYES! IT BURNS!" the villain thrashed, its grip on Bakugo loosening completely.

 

Izuku didn't hesitate. He charged into the dissipating smoke, grabbing Bakugo by the collar of his uniform and hauling him out of the sludge with all his meager physical strength.

 

"Let go of me, you Quirkless nobody!" Bakugo coughed, gagging on the residual gas.

 

"Shut up and run, idiot, the gas is toxic," Izuku snapped, dragging Bakugo backward toward the pro heroes.

 

The crowd was dead silent. The pro heroes stood with their jaws on the ground. A Quirkless middle schooler had just neutralized a villain that four seasoned professionals couldn't touch, using nothing but convenience store cleaning supplies.

 

Suddenly, a massive figure burst through the crowd.

 

"I AM PATHETIC!" All Might roared, blood dripping from his mouth. He had pushed past his limit, forcing his broken body back into its muscular form. He grabbed Bakugo and Izuku, tossing them safely behind him.

 

"DETROIT SMASH!"

 

All Might threw a downward punch that changed the weather. The sheer air pressure snuffed out the fires burning along the street and generated a localized tornado that ripped the sludge villain into microscopic droplets, scattering them across the pavement. It began to rain.

 

The silence that followed was deafening.

 

Then, the crowd erupted into cheers.

 

 

 

The aftermath was a blur of flashing lights and police sirens. Bakugo was currently being praised by the pro heroes for his "bravery" and his "incredible Quirk," despite the fact that he had been a helpless hostage who made the situation worse.

 

Izuku, on the other hand, was surrounded by Kamui Woods and Death Arms, who were glaring at him furiously.

 

"What were you thinking, kid?!" Death Arms scolded. "You could have gotten yourself killed! There was absolutely no reason for you to put yourself in danger like that! Leave it to the pros!"

 

Izuku looked up at the towering hero. A normal middle schooler would have cowered. Izuku just felt annoyed.

 

"Article 14, Section B of the Meta Liberation Regulatory Act," Izuku recited, his voice devoid of emotion. "A civilian is permitted to use reasonable force in defense of another if pro heroes are rendered incapacitated or structurally unable to engage a hostile threat within a three-minute window of severe bodily harm."

 

Death Arms blinked, completely thrown off. "What? I—that doesn't mean—"

 

"Furthermore," Izuku continued, adjusting his charred backpack on his shoulder. "Your Quirk relies on upper body strength, but your grip strength maxes out at roughly 500 kilograms of pressure. The fluid density of the villain meant any physical strike would be absorbed. Kamui Woods is weak to fire, making him a liability in this specific environment. Mt. Lady lacks the spatial clearance to operate."

 

The heroes stared at him, dumbfounded.

 

"You were waiting for a suitable Quirk to arrive," Izuku said, his green eyes narrowing. "In the 147 seconds it would have taken for back-up to navigate through the civilian crowd, the hostage would have suffered permanent brain damage due to hypoxia. My intervention wasn't reckless; it was mathematically necessary to preserve life. I utilized an exothermic chemical reaction to alter the villain's pH level and force a muscular contraction, freeing the hostage. If you want to lecture someone about liability, I suggest you review your own situational awareness protocols."

 

Izuku turned on his heel and walked away, leaving the pro heroes standing in stunned silence.

 

He didn't get far before a familiar voice called out to him.

 

"Deku!"

 

Izuku stopped and turned around. Bakugo was storming toward him, his hands shoved deep into his pockets, his face a mask of conflicting anger and humiliation.

 

"Listen to me!" Bakugo snarled, stopping a few feet away. "I never asked for your help! You didn't save me! I could have handled it myself! Don't think you can look down on me, you Quirkless piece of garbage! You're nothing!"

 

Bakugo spun around and stomped away.

 

Izuku watched him go. Denial. A psychological defense mechanism to protect his fragile superiority complex. He knows his Quirk failed him today. He knows intellect saved him.

 

"I am here!"

 

Izuku didn't even flinch as All Might suddenly slid out from a nearby alleyway in his muscular form, striking a heroic pose, before immediately coughing up a fountain of blood and deflating back into his skeletal state.

 

"All Might," Izuku said calmly. "Should you really be pushing yourself? Your tissue damage is already extensive."

 

"I... I had to come find you," All Might panted, leaning heavily against a telephone pole. "Young man... I came to thank you. And to apologize."

 

Izuku remained silent, waiting for the data.

 

"If I hadn't heard your story on the roof... if I hadn't seen your actions today... I would have been nothing but a fake in a muscle suit," All Might said, looking at Izuku with a profound sense of respect. "You were the only one out of all those heroes, and out of everyone in the crowd, who acted. You, a Quirkless boy, charged in and saved a life while the professionals stood and watched."

 

All Might stepped forward, placing a skeletal hand over his heart. "I was wrong. I told you that you couldn't be a hero without power. But today, you proved that the essence of a hero is not the power they wield, but the spirit that drives them. And because of that... I deem you worthy."

 

Izuku tilted his head. "Worthy of what?"

 

"Worthy of inheriting my power," All Might said, a smile breaking across his gaunt face.

 

Izuku blinked. His brain halted for a microsecond before rebooting. Inheriting? Quirks are genetic. They are biological functions tied to DNA. They cannot be transferred... unless...

 

"A transferable Quirk," Izuku muttered, his eyes widening slightly as the pieces snapped together. "That explains it. Your immense physical power possesses no biological drawback because it isn't native to your DNA. It's an accumulation of power, passed down from person to person. A torch."

 

All Might stared at him, absolutely flabbergasted. "How... how did you figure that out in five seconds?!"

 

"It's the only logical explanation for your existence," Izuku said dismissively. "What is it called?"

 

"One For All," All Might said reverently. "It is a crystallization of power. I have held this Quirk for decades. And I want you, young man, to be my successor."

 

All Might held out his hand, offering Izuku the ultimate prize. The power of a god. The ability to realize his dream of becoming a hero, instantly handed to him on a silver platter.

 

Izuku looked at All Might's hand. He thought about the years of bullying. He thought about Katsuki's explosions. He thought about the pro heroes telling him to give up. He thought about how easy his life would be if he just reached out and took it.

 

If I take this Quirk, I become the Number One Hero, Izuku analyzed. I will possess unmatched physical strength. I will be loved, respected, and feared.

 

But...

 

Izuku's eyes hardened.

 

If I take this Quirk, I am admitting that society is right. I am admitting that a Quirkless person is truly worthless unless they are 'cured' by a magical genetic handout. I would be validating a system that threw me away.

 

Izuku looked up at All Might.

 

"No."

 

All Might froze. His hand hung in the air. "W-What? Did you say... no?"

 

"I said no," Izuku repeated, his voice resolute and piercing. "I am immensely honored, All Might. Truly. But I decline your offer."

 

"But... why?!" All Might sputtered, completely bewildered. "You want to be a hero! You risked your life today! This is your chance to have the power you need to fight villains!"

 

"I don't need your power to fight villains," Izuku said. "I proved that today. You said earlier that without a Quirk, I couldn't stand on the same stage as those with power. You were wrong."

 

Izuku stepped closer to the Symbol of Peace, his presence suddenly feeling much larger than his small frame suggested.

 

"A Quirk is just a tool," Izuku said, tapping his temple. "It's a biological weapon. But weapons can be built. Limitations can be circumvented through technology, strategy, and applied physics. If I take your Quirk, I become just another hero relying on brute force. But if I succeed without one..."

 

Izuku smiled—a sharp, fiercely intelligent smile.

 

"...I will permanently dismantle the entire foundation of Quirk supremacy. I will prove to the world that the human mind is the ultimate superpower."

 

All Might stared at the boy. For the first time in his life, Toshinori Yagi felt a chill run down his spine that had nothing to do with All For One. The intellect, the absolute unshakeable conviction radiating from this middle schooler was terrifying. It was brilliant.

 

"You..." All Might whispered. "You are walking a very dark, very difficult path, young man. The world will not accept you easily."

 

"I don't need them to accept me," Izuku said, adjusting his backpack. "I just need them to stay out of my way."

 

Izuku turned and began to walk home. His mind was no longer focused on heroes, or All Might, or Katsuki. His mind was already miles away, calculating, designing, building.

 

He didn't need a Quirk. He needed a forge. He needed titanium plating, carbon-fiber muscle weaves, localized EMP emitters, and kinetic shock absorbers.

 

As Izuku Midoriya walked into the setting sun, he wasn't a Quirkless victim anymore. He was a 200-IQ prodigy with a singular, mathematically precise goal.

 

He was going to conquer U.A. High School. And he was going to do it with his bare hands and his beautiful, brilliant mind.

 

Takoba Municipal Beach was a monument to societal complacency. For years, the ocean currents had deposited the city’s refuse onto the sand, transforming a beautiful coastline into an illegal dumping ground. Refrigerators, rusted cars, shattered microwaves, and mountains of twisted steel sat rotting in the salt air. To the average citizen, it was an eyesore. To the local government, it was a logistical nightmare too expensive to clean.

 

To Izuku Midoriya, it was a goldmine.

 

It was 4:00 AM on a Tuesday, exactly ten months before the U.A. High School Entrance Exam. The sky over Musutafu was a bruised purple, and the air was frigid. Izuku stood at the edge of the seawall, the wind whipping his wild green hair around his face. He held a modified tablet—pieced together from three broken laptops and an old smartphone—and typed furiously.

 

Total mass of refuse estimated at roughly 1,500 metric tons, Izuku’s mind calculated, his eyes scanning the silhouettes of the junk mountains. Composition: 40% ferrous metals, 20% aluminum alloys, 15% plastics and polymers, 10% electronic waste, 15% organic/biodegradable materials. The structural integrity of the lower scrap strata is compromised by saltwater oxidation. However, the internal components of the discarded appliances—specifically the copper wiring, neodymium magnets from speaker systems, and lithium-ion battery cells—are largely salvageable.

 

Izuku didn't just want to clean the beach to build physical muscle. He needed materials. If he was going to rival the biological firepower of his peers, he needed a technological arsenal, and high-grade support gear was prohibitively expensive. Therefore, he had to build his own forge.

 

He walked down the concrete steps onto the sand, pulling a pair of heavy-duty welding gloves onto his hands. He approached a rusted pickup truck half-buried in the sand. He didn't just try to lift it; he analyzed it.

 

Fulcrum point. Center of gravity. Izuku wedged a heavy steel pipe beneath the truck's rear axle, placed a dense cinderblock underneath as a pivot, and applied his body weight. The simple physics of leverage magnified his meager force, groaning against the rust until the truck tipped backward, exposing its undercarriage.

 

Izuku spent the first two months doing nothing but harvesting and organizing. He didn't work blindly. He built a system.

 

By week three, he had successfully extracted a functioning diesel generator from a wrecked fishing boat. By week five, he had cannibalized the motors of twelve different washing machines, reprogramming their motherboards to create a crude, automated sorting system. By week eight, he had cleared out a massive, watertight shipping container buried under a mountain of tires, converting it into a hidden, subterranean workshop.

 

The interior of the container glowed with the blue light of salvaged monitors and the harsh orange heat of a makeshift induction smelter. Here, Izuku was a god of creation.

 

"Drone unit designation: Scrapper-One. Status report," Izuku muttered, adjusting the safety goggles over his eyes as he welded a joint on a metallic frame.

 

On the workbench beside him, a mechanized unit roughly the size of a large dog whirred to life. It was ugly—built from the chassis of a lawnmower, the treads of a miniature snowblower, and the optical sensors of a discarded security camera. But it was entirely functional.

 

The drone chirped, a line of code scrolling across Izuku’s monitor. [Scrap sorted: 450 lbs of high-carbon steel. Smelting efficiency at 82%.]

 

"Good boy," Izuku murmured.

 

While his automated systems processed the raw materials, Izuku began processing himself. He knew that technology alone was not enough. A suit of armor was only as effective as the biological machine piloting it. If his reaction times were slow, if his cardiovascular endurance failed, he would be a sitting duck, no matter how advanced his gear was.

 

His physical training was a masterclass in biomechanics and applied anatomy. He didn't waste time with traditional bodybuilding. Bulky muscles required higher caloric intake and consumed oxygen at an accelerated rate, leading to faster fatigue. Izuku needed lean, hyper-efficient muscle fiber. He needed explosive kinetic potential.

 

Every evening, after the sun went down, Izuku transformed the cleared sections of Takoba Beach into a brutal obstacle course. He sprinted through the deep sand wearing a vest weighted with scrap lead to increase his VO2 max and strengthen his fast-twitch muscle fibers. But cardiovascular endurance was only the foundation. Combat was the real necessity.

 

Izuku’s 200 IQ turned martial arts into pure mathematics. He studied Krav Maga, Aikido, and close-quarters combat (CQC) manuals, but he discarded the traditional philosophies behind them. He didn't care about "flow" or "spiritual center." He cared about anatomy.

 

The human body is an inherently flawed machine, Izuku thought as he stood before a heavy punching bag he had fashioned from a tarp filled with dense, wet sand. Quirks may alter external outputs—fire, ice, explosions—but 95% of Quirk users still possess a baseline human skeletal and nervous system. They still have a brachial plexus. They still have a vagus nerve. They still have a liver.

 

Izuku struck the bag. Crack.

 

Strike one: The common peroneal nerve located on the lateral aspect of the fibula. Requires roughly 25 to 30 pounds of localized PSI to induce temporary paralysis of the lower leg. Effect: Opponent's mobility is instantly reduced by 50%.

 

He pivoted, driving his elbow into the center of the bag. Crack.

 

Strike two: The solar plexus. A direct kinetic shock to the celiac plexus nerve network causes a severe spasm of the diaphragm. Effect: Immediate respiratory failure and oxygen deprivation to the brain, inducing panic and incapacitation.

 

He swept his leg low, followed by a rapid, precise strike to the top of the bag.

 

Strike three: The vagus nerve at the side of the neck. A sudden, sharp impact disrupts the baroreceptors, tricking the brain into thinking blood pressure has spiked dangerously high. The brain responds by rapidly dilating blood vessels and dropping the heart rate. Effect: Instantaneous syncope. Unconsciousness.

 

Izuku practiced these sequences thousands of times. He programmed automated striking dummies using pneumatic pistons to randomly attack him, forcing his brain to recognize telegraphing movements—a shift in the shoulders, the widening of the eyes, the micro-tension of a calf muscle—and react automatically. To Izuku, hand-to-hand combat wasn't a brawl; it was a surgical operation.

 

As the months bled into winter, the beach grew emptier, but Izuku’s workshop grew denser.

 

It was during his seventh month of training that Izuku took a break to check the hero news networks on his monitors. A headline caught his eye: THIRD-YEAR UA STUDENT MIRIO TOGATA SHATTERS RECORDS IN MOCK BATTLE! POWER LEVEL OFF THE CHARTS!

 

Izuku leaned in, his green eyes scanning the video footage attached to the article. It showed a blonde, muscular teenager effortlessly destroying a platoon of robotic enemies. But what caught Izuku’s attention wasn't Togata's Permeation Quirk; it was the sheer, concussive force of his physical strikes. The air pressure warping around his fists.

 

Izuku’s mind immediately connected the data points. Togata Mirio. Previously known for a complex, purely defensive Permeation Quirk. Now exhibiting catastrophic levels of physical enhancement. The power output perfectly mirrors the kinetic shockwaves produced by All Might.

 

Izuku sat back in his chair, a faint smile playing on his lips. So, he found a successor. Someone who already had the physical vessel prepared. Good. The world has its new Symbol of Peace.

 

He looked down at his own grease-stained hands. And I am completely free to operate in the shadows.

 

With the burden of All Might’s legacy definitively passed to someone else, Izuku poured every ounce of his staggering intellect into his final project: his Entrance Exam gear.

 

The U.A. practical exam was a point-based system centered around the destruction of large-scale robotic targets. Izuku knew he couldn't punch through reinforced steel. So, he designed a suit that would do the work for him.

 

He called it the "Aegis-One" prototype.

 

The undersuit was woven from a custom shear-thickening fluid (a non-Newtonian polymer) sandwiched between layers of synthetic Kevlar. Under normal conditions, the suit was flexible, allowing Izuku complete freedom of movement. But upon sudden kinetic impact—like a punch, an explosion, or a fall—the molecules locked together instantly, hardening into a rigid shell that dispersed the force across the entire surface area of the suit.

 

But defense was only half the equation. Izuku needed offense.

 

For his arms, he constructed pneumatic gauntlets. Using salvaged high-pressure air canisters and reinforced titanium tubing, he designed a system that would allow him to deliver a punch with the force of a hydraulic press. He could regulate the PSI via a neural-link sweatband sensor. A light tap could shatter a concrete block; a maximum output punch could dent a steel blast door.

 

For mobility, he designed the "Vector Boots." They utilized compressed gas and heavy-duty kinetic springs to absorb the shock of a landing and redirect it into upward momentum, allowing Izuku to leap incredible distances and survive falls from three-story buildings.

 

Finally, his belt held his tactical ordinance. He had spent three weeks carefully synthesizing chemical compounds to create non-lethal, high-yield tools:

1. EMP Grenades: Small, disc-shaped devices that utilized an explosive flux-compression generator to fry unshielded circuitry within a five-meter radius.

2. Chaff-Smoke Emitters: Canisters that released a dense smokescreen laced with aluminum particulates to scramble optical and thermal sensors.

3. A high-tensile carbon-nanotube grappling hook integrated into his left wrist gauntlet.

 

By the tenth month, Takoba Beach was pristine. Not a single piece of trash remained. The white sand gleamed under the rising sun. And standing at the shoreline, breathing in the salty air, Izuku Midoriya was no longer the frail, bullied kid from Aldera Junior High. His body was corded with dense, wiry muscle. His mind was a supercomputer.

 

It was time to apply to U.A.

 

 

 

Principal Nezu, the chimera mammal who possessed the High Spec Quirk, sat behind his massive mahogany desk, sipping a cup of Darjeeling tea. To his right stood Eraserhead (Shota Aizawa), looking perpetually exhausted. To his left stood Present Mic (Hizashi Yamada).

 

"We have an anomalous situation," Nezu said, his beady black eyes gleaming with intense amusement. He placed a thick file on the desk.

 

"What is it?" Aizawa grunted. "Another legacy kid with an overpowered Quirk causing property damage?"

 

"Quite the opposite," Nezu chuckled. "I am holding the results of the U.A. Written Entrance Exam. As you know, the written test is famously brutal, designed to weed out those who rely solely on their Quirks and lack cognitive reasoning."

 

"Right, right," Present Mic leaned in. "So who got the top score? That Yaoyorozu girl from the recommendation exams?"

 

"Yaoyorozu Momo scored a 98.5%," Nezu said, taking another sip of tea. "An exceptional score. But she is not the top." Nezu pushed a single sheet of paper forward. "The top score is 100%. A perfect score. But that is not what makes it an anomaly."

 

Aizawa frowned, leaning down to look at the paper. "No one has ever scored a perfect 100%. The final three essay questions are designed to have no objectively correct answer; they are ethical paradoxes."

 

"Indeed!" Nezu clapped his paws together. "And yet, this applicant didn't just answer them. He mathematically deconstructed the ethical paradoxes, cited three centuries of legal precedent, calculated the socioeconomic fallout of each potential hero action, and provided a tertiary solution that completely circumvented the paradox altogether. It was, quite frankly, the most brilliant piece of analytical writing I have ever read in my life."

 

Nezu paused, his smile widening into something almost predatory. "And he did it in forty-two minutes. The allotted time is two hours."

 

Aizawa’s visible eye widened slightly. "Who is it?"

 

"Izuku Midoriya," Nezu said. "Middle schooler. And... he is entirely Quirkless."

 

The room fell dead silent.

 

"Quirkless?" Present Mic echoed, adjusting his orange glasses. "Are you kidding me? A Quirkless kid is applying for the Hero Course? That's suicide! The practical exam is against massive robots! He'll be crushed!"

 

"Which brings me to the second anomaly," Nezu continued, sliding a thick blueprint dossier across the desk. "Along with his application, Mr. Midoriya submitted a formal petition under U.A. Bylaw 4-A, requesting permission to utilize self-made Support Gear for the practical exam. He attached the schematics."

 

Aizawa picked up the blueprints. His eyes scanned the dense mathematical formulas, the structural diagrams of the pneumatic gauntlets, and the chemical composition of the EMP grenades. Aizawa was not an engineer, but he knew enough about combat gear to recognize brilliance.

 

"He built this himself?" Aizawa asked, his voice low. "This is professional-grade. No, this is beyond some of the gear our Support Course third-years are making."

 

"Precisely," Nezu said. "The Board of Education flagged his application for immediate rejection based on his Quirkless status. I overruled them."

 

"You did what?" Present Mic exclaimed. "Nezu, it's too dangerous! The Zero Pointer alone—"

 

"A hero is not defined by their genetics, Yamada," Nezu interrupted, his tone suddenly sharp and authoritative. "My own Quirk simply grants me superior intelligence. Am I not a hero? If this boy has used his mind to close the gap between biology and technology, it is our duty as educators to test him. I have called him in for a pre-exam interview."

 

Exactly ten minutes later, the door to the principal's office opened.

 

Izuku Midoriya walked in. He wore his standard black middle school uniform, but his posture was completely different from a typical nervous teenager. His back was straight. His breathing was measured. His green eyes immediately swept the room, darting from Aizawa to Present Mic, and finally to Nezu.

 

Analysis, Izuku's brain initiated instantly.

Subject 1: Shota Aizawa. Pro Hero: Eraserhead. Quirk: Erasure. Nullifies emitter and transformation Quirks via visual contact. Equipment: Capture weapon constructed from carbon-fiber and an unknown metal alloy. Weakness: Dry eye syndrome and combat effectiveness strictly limited to close-quarters martial arts.

Subject 2: Hizashi Yamada. Pro Hero: Present Mic. Quirk: Voice. Directional sonic blasts. Weakness: Vulnerable to low-frequency phase cancellation and his own vocal cord degradation.

Subject 3: Principal Nezu. Quirk: High Spec. Unparalleled cognitive processing. The most dangerous entity in the room.

 

"Ah, Mr. Midoriya!" Nezu beamed, gesturing to the chair opposite his desk. "Please, take a seat. I am Principal Nezu. The one who could be a dog, a mouse, or a bear, but more importantly... I am the Principal!"

 

"An amalgamation of mammalian DNA enhanced by a rare genetic mutation," Izuku replied smoothly, taking his seat. "It’s an honor to meet you, sir."

 

Nezu’s eyes sparkled. "You're a very difficult boy to read, Midoriya. Most students are trembling when they sit in that chair."

 

"Fear is a biological response to the unknown or the uncontrollable," Izuku stated calmly. "I possess the schematics of this building, I know the Quirks of every hero in this room, and I know exactly why I was called here. There is no variable left unknown. Therefore, no fear."

 

Aizawa narrowed his eyes. "Cocky."

 

"Factual," Izuku corrected, meeting Aizawa’s gaze without flinching. "You called me here to assess whether my Support Gear violates the rules of the practical exam, and to judge whether a Quirkless student is a liability to your insurance policies."

 

Present Mic choked on his own spit. Aizawa let out a low whistle.

 

Nezu laughed aloud. "Marvelous! Straight to the point. Very well. I have reviewed your schematics. The EMP grenades are borderline illegal for a civilian to possess, and the pneumatic gauntlets generate enough kinetic force to shatter a human sternum."

 

"The exam targets are not human," Izuku countered immediately. "They are U.A. specialized combat robotics. Specifically, they are powered by internal combustion engines and localized battery cells. My gear is calibrated exclusively for anti-armor and electronic warfare. I have hard-coded biometric locks into the gauntlets; they will not fire with lethal force if the target's thermal signature matches a human being."

 

Nezu raised an eyebrow. "You built a biometric safety override into gear you assembled in a junkyard?"

 

"I don't leave room for catastrophic error, sir."

 

Nezu leaned forward, resting his chin on his paws. "Let me ask you a philosophical question, Midoriya. Why do you want to be a hero? You have an intellect that could cure diseases, revolutionize clean energy, or make you a billionaire before you turn twenty. Why choose a profession that requires you to bleed?"

 

Izuku looked down at his hands, encased in the leather of his custom gloves. He thought of Bakugo. He thought of the sludge villain. He thought of a society that treated people like him as less than human.

 

"Because society is currently operating under a flawed algorithm," Izuku said softly, but his voice carried an immense, heavy gravity. "People believe that heroism is a genetic lottery. They believe that power dictates morality. As long as that belief persists, the strong will exploit the weak, and the weak will wait helplessly for a savior who may never come."

 

Izuku looked up, his green eyes burning with a cold, absolute fire.

 

"I don't just want to save people, Principal Nezu. I want to shatter the illusion of Quirk supremacy. I want to prove that the human mind, sheer willpower, and innovation are greater than any power you can be born with. I want to build a new blueprint for what a hero can be."

 

The room was completely silent. Aizawa stared at the kid, feeling a rare shiver of genuine respect. This wasn't the blind, naive idealism he hated in most students. This was calculated, weaponized conviction.

 

Nezu smiled. It was a terrifying smile.

 

"Request approved, Midoriya Izuku," Nezu said. "You may use your gear. Let us see if your blueprint can survive the U.A. Entrance Exam."

 

 

 

One week later. The U.A. Practical Exam Testing Grounds. Battle Center B.

 

Hundreds of students stood before the massive, towering gates of the mock city. The tension in the air was palpable. Teenagers were stretching, hyping themselves up, sparks flying from their fingers, small localized winds swirling around them.

 

Izuku stood near the back of the crowd, entirely still. He was wearing the Aegis-One suit. It was sleek, matte-black, and heavily utilitarian. The kinetic-absorption undersuit clung to his frame, overlaid with rigid, lightweight composite plating over his vitals. The heavy pneumatic gauntlets rested on his forearms, emitting a very faint, rhythmic hiss of compressed air. A specialized visor covered the top half of his face, its HUD currently booting up and running diagnostic checks.

 

[System Online. Pneumatic pressure at 100%. Vector boots charged. Heart rate: 85 BPM. Optimal.]

 

"Hey!" a harsh, grating voice snapped.

 

Izuku turned his head slightly. Katsuki Bakugo was stomping toward him, his red eyes burning with absolute fury. Bakugo had barely recognized Izuku in the tactical armor, but the messy green hair was unmistakable.

 

"Deku," Bakugo growled, his palms already popping with micro-explosions. "What the hell do you think you're wearing? Are you cosplaying? I told you not to apply to U.A.!"

 

Izuku’s HUD immediately tracked Bakugo. [Threat detected. Heart rate: 130 BPM. Elevated cortisol levels. Predicted attack vector: Right hook overhead blast.]

 

"The exam is about to begin, Bakugo," Izuku said smoothly, his voice slightly filtered through the suit’s communicator. "I suggest you conserve your nitroglycerin. You'll need it."

 

"Don't you dare look down on me!" Bakugo roared, raising his hand.

 

Before he could unleash a blast, the towering gates of the mock city began to groan open.

 

"RIGHT, LET'S START!" Present Mic’s voice boomed from the massive speakers overhead. "WHAT'S THE MATTER? THERE ARE NO COUNTDOWNS IN REAL BATTLES! RUN, RUN, RUN!"

 

The crowd hesitated for a fraction of a second.

 

Izuku did not.

 

He engaged the Vector Boots. Compressed gas fired into the kinetic springs. With a sharp CRACK that kicked up a cloud of dust, Izuku launched himself over the heads of the crowd, clearing the gates before they were even fully open. He soared through the air, completely bypassing the bottleneck at the entrance, and landed flawlessly on the roof of a three-story building just inside the city.

 

The Quirked students stared in shock.

 

"What the hell was that?!" someone yelled.

 

Izuku was already moving. From his elevated vantage point, his HUD mapped the mock city. He calculated the spawn points of the robotic targets based on the structural layout of the main avenues.

 

Three 1-Pointers approaching from Sector 4. A cluster of 2-Pointers in Sector 6. Objective: Maximize point acquisition while minimizing gear degradation.

 

Izuku dropped from the roof, his boots absorbing the impact as he landed in the middle of an intersection.

 

Three 1-Pointers rounded the corner. They were essentially heavily armored unicycles equipped with dual machine guns loaded with rubber bullets.

 

"Target acquired," the robotic voices droned.

 

They opened fire.

 

Izuku didn't dodge. The rubber bullets struck his Aegis-One suit. The non-Newtonian polymer instantly hardened upon impact, completely nullifying the kinetic force. The bullets bounced off him like pebbles.

 

Analysis: The 1-Pointers rely on visual targeting. Their chassis is reinforced steel, but their optical sensors are exposed glass.

 

Izuku reached to his belt, pulling a smoke-chaff canister. He rolled it forward. It detonated, filling the street with a thick cloud of aluminum-laced smoke. The robots' targeting lasers instantly scrambled, sweeping wildly as their radar was blinded.

 

Izuku sprinted through the smoke. He closed the distance in two seconds. He ducked under a wildly swinging mechanical arm of the first robot, brought his right fist back, and activated the pneumatic gauntlet.

 

PSI Output: 1500.

 

He punched the robot dead center in its central processing unit. The hydraulic piston fired violently. The sheer force of the impact caved the steel chassis inward, shattering the motherboard and instantly shutting the machine down.

 

He didn't pause. He pivoted on his heel, grabbing the ruined chassis of the first robot and hurling it—using the residual kinetic spring in his boots—directly into the second robot, crushing its optical sensor.

 

As the third robot re-oriented itself, Izuku fired his grappling hook. The carbon-nanotube wire wrapped around the robot's primary drive axle. Izuku yanked backward with his body weight, pulling the axle completely out of alignment and causing the robot to violently crash into a brick wall.

 

Total time elapsed: 12 seconds. Points acquired: 3.

 

In the observation room, the pro heroes were watching the monitors in silence.

 

"Look at monitor 4," Midnight said, her eyes wide. "Who is that kid in the black armor? His movements... there's zero wasted energy. It's like he already knows what the robots are going to do before they do it."

 

"That's Midoriya," Nezu said, sipping his tea. "The Quirkless applicant."

 

"Quirkless?!" Snipe exclaimed, adjusting his mask. "He just dismantled three units faster than the kids with physical enhancement Quirks!"

 

"He's not fighting them," Aizawa noted, his eyes locked on Izuku’s monitor. "He's dissecting them. He's exploiting structural weak points. He's using the environment. He is fighting like a veteran."

 

Back in the mock city, Izuku was rapidly accumulating points. He was a ghost on the battlefield. While the other students were screaming, blasting, and exhausting themselves, Izuku was operating with cold, clinical efficiency.

 

He encountered a massive 3-Pointer—a heavily armored tank-like robot with dual missile launchers. Several students were pinned down behind rubble, unable to scratch its armor.

 

Izuku analyzed the beast. Armor thickness: 4 inches of hardened steel. Lethal force required to penetrate. Alternative solution required.

 

He grappled up to a fire escape overlooking the street. He didn't attack the armor; he attacked the nervous system. He unclipped an EMP grenade from his belt, primed it for a focused, directional blast rather than a radial one, and dropped exactly onto the "neck" joint of the 3-Pointer.

 

He triggered the EMP. A localized burst of electromagnetic radiation fried the robot's secondary motor-control functions. The robot froze, its heavily armored weapons systems offline, but its primary battery still functional.

 

Izuku dropped down onto the paralyzed robot's back. He pulled out his modified tablet from a secure pouch on his chest. He popped open a maintenance panel on the robot's neck, located the diagnostic port, and plugged his tablet in.

 

Initiating override protocol. Bypassing U.A. sub-routines. Rerouting motor control to external device.

 

It took him exactly fourteen seconds to hack the most advanced combat AI U.A. possessed.

 

The 3-Pointer’s electronic eyes shifted from red to a cool, subservient blue.

 

Izuku stood atop the massive robot. He tapped a command onto his tablet. The 3-Pointer raised its massive cannons and fired a volley of compressed-air missiles down the street, instantly destroying a cluster of five 2-Pointers that were advancing on the pinned students.

 

The students looked up at the black-armored figure standing atop the U.A. tank, utterly bewildered.

 

"Thanks for the assist!" Izuku called out mathematically, calculating his new score. Total points: 54. Passing threshold statistically guaranteed. Conserving stamina.

 

In the observation room, Present Mic dropped his microphone.

 

"He... he hacked it," Snipe said, his voice trembling slightly. "He hacked a U.A. 3-Pointer and turned it into a mobile turret. Is that even allowed?!"

 

"There are no rules against electronic warfare in the handbook," Nezu giggled, vibrating with excitement. "Oh, this boy is a treasure!"

 

"He has enough points to pass," Aizawa said quietly. "But the true test of U.A. isn't just taking out villains. Let's see how he handles the uncontrollable."

 

Aizawa reached forward and pressed a large red button on the console.

 

In the mock city, the ground began to violently shake. Izuku, still perched atop his hacked 3-Pointer, immediately checked his internal gyroscope. Seismic activity. Localized. Not a natural earthquake. A massive underground hydraulic displacement.

 

At the far end of the main avenue, a building exploded outward.

 

Rising from the dust and debris was a mechanical monstrosity that blotted out the sun. It was the Zero Pointer. It was the size of a skyscraper, a literal walking dreadnought.

 

The other students screamed in absolute terror and began fleeing in the opposite direction.

 

Izuku stared at it. His HUD rapidly attempted to calculate its mass. [Error. Subject mass exceeds standard parameters. Estimated weight: 4,000 metric tons.]

 

Combat with this entity is mathematically impossible, Izuku deduced instantly. My pneumatic gauntlets at maximum output wouldn't even dent its toe. The EMP grenades do not possess the radial yield to affect a chassis of this size. The logical action is immediate retreat.

 

Izuku turned to run. But his enhanced audio sensors picked up a sound over the roar of the massive treads.

 

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

 

Izuku’s head snapped back. Roughly forty meters away, directly in the path of the advancing Zero Pointer, a girl with round cheeks and short brown hair (Ochaco Uraraka) was trapped under a massive slab of concrete. The Zero Pointer was raising its titanic foot. She had less than thirty seconds before she was crushed.

 

Izuku's brain flooded with conflicting data.

Rescue required.

Biological limitation: I cannot lift that slab of concrete in time.

Technological limitation: My gear cannot destroy the robot.

Probability of death if engaged: 98.7%.

 

To hell with the odds, Izuku thought.

 

He didn't run away. He ran toward the behemoth.

 

"What is he doing?!" Midnight gasped in the observation room. "He can't fight that thing! Stop the exam!"

 

"Wait," Nezu commanded, his eyes glued to the screen.

 

Izuku sprinted full speed toward the trapped girl. But he wasn't looking at her. He was looking at the environment. He was looking at the buildings lining the street.

 

Physics. It all comes down to physics. If I cannot destroy the object, I must redirect its kinetic energy, or use a greater mass to stop it.

 

Izuku bypassed the girl, much to her horror, and sprinted straight into the base of a heavily damaged, six-story concrete building right next to the Zero Pointer’s path. The building’s structural integrity had already been compromised by the robot's entrance.

 

Izuku analyzed the load-bearing pillars of the building.

 

Pillar A, B, and C are supporting the southern facade. If I remove them simultaneously, the center of gravity will shift dramatically, causing the 600-ton structure to collapse outward into the street... directly onto the Zero Pointer's knee joint.

 

Izuku didn't have explosives strong enough to blow the pillars. He had to use himself.

 

He deactivated all safety limiters on his right pneumatic gauntlet.

[WARNING: Safety limiters offline. Structural failure of gauntlet imminent. Severe physical trauma to user's skeletal system highly probable.]

 

"Override," Izuku snarled.

 

He stepped up to Pillar A. He pulled his fist back and fired. PSI Output: Maximum.

 

CRUNCH. The steel-reinforced concrete shattered like glass. The recoil shot up Izuku’s arm, and he felt the sickening pop of his right shoulder dislocating. He gritted his teeth, ignoring the agony through sheer adrenaline.

 

He sprinted to Pillar B. His right arm hung uselessly. He raised his left arm.

 

CRUNCH. Pillar B obliterated. The building groaned, a terrifying sound of tons of concrete beginning to shift. His left gauntlet hissed violently, a pressure seal blowing out and spraying scalding gas across his forearm.

 

He staggered to Pillar C. Both gauntlets were critically damaged. Both of his arms were structurally compromised.

 

Vector boots. Maximum kinetic release.

 

Izuku leaped into the air, twisting his body, and delivered a devastating, gas-powered axe kick directly into the center of Pillar C.

 

The pillar snapped. The boots sparked and died.

 

Izuku hit the ground, rolling painfully. Above him, the physics equation he had set into motion finally resolved.

 

With a deafening roar, the six-story building collapsed. Thousands of tons of concrete, steel, and glass pitched forward, crashing down onto the street with the force of a meteor.

 

The avalanche of debris slammed directly into the side of the Zero Pointer’s massive leg. The sheer kinetic force of the falling building overwhelmed the robot's gyroscopic stabilizers. The metal of its knee buckled under the weight.

 

The Zero Pointer let out a mechanical wail as its center of mass was completely destroyed. It toppled over like a felled redwood, crashing into the ruined city blocks away from Uraraka, permanently disabled by an avalanche of U.A.'s own architecture.

 

A buzzer sounded across the city.

 

"TIME'S UP!" Present Mic’s voice echoed.

 

The dust slowly settled over the ruined street. Uraraka coughed, looking up. The giant robot was gone, buried under a mountain of rubble.

 

Standing a few feet away from her, breathing heavily, was Izuku. His black armor was covered in dust. His right arm was visibly dislocated, hanging at an unnatural angle. His gauntlets were smoking, his boots sparking.

 

He slowly walked over to her. He couldn't lift the rubble off her with his broken arms. But he still had his intellect. He used his foot to kick a sturdy iron rebar under the concrete slab, kicking a chunk of debris beneath it to create a fulcrum. He stepped on the end of the rebar, using leverage to lift the slab just enough for her to scramble out.

 

"Are... are you okay?" Uraraka breathed, looking at his mangled armor.

 

Izuku didn't wince. His HUD was flashing dozens of red error codes, tracking his injuries. Right humerus dislocated. Left forearm first-degree burns. Muscle tearing in both calves. Equipment critically damaged. Total cost of repairs: roughly 45,000 yen.

 

Izuku looked down at the girl. He manually triggered the release on his visor, the metal sliding back to reveal his sweat-soaked face, his green eyes calm and analytical.

 

"I am mathematically sound," Izuku replied simply. Then, his adrenaline crashed, and the darkness took him.

 

 

 

In the observation room, not a single hero spoke. They had just witnessed a Quirkless teenager systematically dismantle the U.A. exam using junk-yard science, hack their billion-dollar military AI, and weaponize gravity and architecture to defeat an unstoppable behemoth.

 

Aizawa stared at the frozen image of the collapsed building on the monitor.

 

"He didn't just pass," Aizawa said, his voice carrying a profound weight. "He broke the entire system."

 

Principal Nezu took a long, slow sip of his tea, a tear of pure, unadulterated joy pricking the corner of his eye.

 

"Eraserhead," Nezu said softly. "I believe we have just found our new Number One."

 

The human body is an astonishing machine, but it is ultimately bound by the immutable laws of biology. Bones take weeks to knit. Torn muscle fibers require rest and protein synthesis to rebuild. A dislocated shoulder, even once relocated, leaves the surrounding cartilage and ligaments inflamed and structurally weakened.

 

Izuku Midoriya sat in the dim, blue glow of his subterranean workshop beneath Takoba Municipal Beach, his right arm bound tightly in a high-tension compression sleeve. It had been exactly one week since the U.A. Entrance Exam. One week since he had shattered his own body to trigger a localized architectural collapse on the Zero Pointer.

 

He operated the soldering iron with his left hand, his movements slightly slower but no less precise.

 

Error assessment, Izuku thought, his eyes tracking the micro-weld he was applying to a new circuit board. Aegis-One prototype failed under maximum stress. The pneumatic gauntlets lacked sufficient recoil-dampening mechanisms. The kinetic force required to shatter reinforced concrete exceeded the tensile strength of the titanium housing, causing a blowback effect that traveled directly into my radius and ulna, culminating in a glenohumeral joint dislocation.

 

Solution: Redesign the shock-absorption matrix. Incorporate a secondary micro-hydraulic recoil system and line the interior gauntlet sleeve with a thicker layer of shear-thickening fluid to disperse kinetic blowback across a wider surface area.

 

He set the soldering iron down and picked up a heavy, matte-black bracer. This was Aegis-1.2. Sleeker, lighter, but infinitely more durable.

 

He didn't have the luxury of biological regeneration. He couldn't just drink milk and wait for his bones to harden. If he was going to walk into a school filled with teenagers who could sweat nitroglycerin, run at the speed of sound, or create fire from their skin, his armor needed to be an extension of his own nervous system.

 

Suddenly, the proximity sensors at the entrance of his hidden container beeped.

 

"Scrapper-One, mute audio," Izuku commanded the small, tread-bound drone resting by his desk.

 

Izuku checked his monitor. It was a mail courier, dropping a standard-issue U.A. envelope into the makeshift mailbox Izuku had installed near the beach's retaining wall.

 

Izuku rode his rigged pulley-elevator to the surface, retrieved the envelope, and returned to his lab. He didn't tear it open with trembling hands. He carefully sliced the seal with a scalpel. A small, metallic disc slipped out and clattered onto the metal desk.

 

A holographic projector.

 

The disc whirred to life, projecting a crisp, three-dimensional image. But it wasn't All Might, as Izuku knew was standard for the hero course acceptances this year.

 

It was Principal Nezu.

 

"Greetings, Midoriya Izuku!" the chimera beamed, sipping from a holographic teacup. "If you are watching this, it means you have survived your own engineering. A remarkable feat! You scored 54 rescue points and zero villain points, passing the exam with flying colors."

 

Nezu leaned forward, his black eyes glinting with a sharp, terrifying intelligence that Izuku instantly respected.

 

"The U.A. board was quite divided on you, Midoriya. Many believe you are a liability. Many believe your reliance on technology goes against the spirit of the 'biological hero.' But I see things differently. I see a boy who looked at an impossible equation and simply rewrote the math. You are officially accepted into Class 1-A of the U.A. Hero Course. Do not prove me wrong."

 

The hologram flickered and died.

 

Izuku stared at the empty space above the disc. He didn't cheer. He didn't cry. His heart rate elevated by a mere five beats per minute. He simply reached out, picked up his hydro-wrench, and went back to work on his gauntlets.

 

Variable confirmed. Objective achieved. Now, the actual work begins.

 

 

 

The first day of U.A. High School arrived with a crisp spring breeze. The towering glass structure of the academy gleamed in the morning sun, a citadel of superhuman potential.

 

Izuku walked through the front gates, blending into the crowd of students. To the naked eye, he looked completely ordinary. He wore the standard gray blazer, red tie, and dark pants. But beneath the uniform, Izuku was armed for war.

 

He wore the Aegis-1.2 kinetic-absorption undersuit instead of standard underwear. Around his wrists, heavily concealed by the long sleeves of his blazer, were the compacted versions of his pneumatic bracers—designed to be modular, so they could quickly unfold and lock into place over his hands if combat was initiated. His shoes were a discreetly modified version of his Vector Boots, the thick soles hiding high-tension kinetic springs and micro-canisters of compressed CO2.

 

He navigated the labyrinthine hallways until he found the massive, imposing door labeled 1-A.

 

The door size is designed to accommodate extreme mutant-type Quirks, Izuku analyzed as he reached for the handle. Logical, but inefficient for HVAC temperature control.

 

He slid the door open.

 

The classroom was already loud. Izuku's eyes immediately swept the room, taking a mental snapshot of every variable, every student, every potential threat.

 

Tenya Iida. Quirk: Engine. Currently lecturing Katsuki Bakugo. Posture indicates a rigid adherence to rules, likely from a privileged, structured background. Muscle density in the calves is exceptional.

 

Katsuki Bakugo. Quirk: Explosion. Feet on the desk. Aggression levels at baseline high. A psychological superiority complex masking deep-seated insecurities.

 

Ochaco Uraraka. Quirk: Zero Gravity. Friendly demeanor. Her Quirk likely manipulates the Higgs field around localized objects, removing their mass variable. Extremely dangerous if used lethally, but her psychology indicates pacifistic tendencies.

 

"Ah! It's you!"

 

Izuku turned his head. Uraraka was bounding toward him, a bright smile on her face. "The boy with the black armor! You saved me! I never got to thank you properly. Your arm looked so bad, are you okay?"

 

"The glenohumeral joint has been relocated and the micro-tears in the surrounding tissue are healing at a projected rate of 85%," Izuku replied evenly, his face completely deadpan. "I am functioning at an acceptable capacity."

 

Uraraka blinked, her smile faltering into a look of utter confusion. "Uh... that's... good?"

 

"Deku."

 

The word cut through the classroom noise like a razor blade.

 

Bakugo had stopped arguing with Iida and was now glaring at Izuku, his red eyes narrowed into slits of pure venom. He stood up, kicking his chair back.

 

"I don't know what kind of cheap tricks you pulled to get in here, you Quirkless nobody," Bakugo growled, stalking forward. "But if you think some metal toys put you on my level, you're dead wrong. I'm going to tear you apart."

 

The classroom fell silent. The other students exchanged nervous glances, realizing the intense, homicidal history between the two boys.

 

Izuku didn't flinch. His eyes calmly tracked the micro-expressions on Bakugo's face.

 

"Your threats are statistically irrelevant, Bakugo," Izuku said, his voice quiet but carrying a piercing clarity that echoed in the silent room. "We are in a controlled educational environment. Any unprovoked physical assault will result in your immediate expulsion. You prioritize your ambition to become the Number One Hero above all else. Therefore, the probability of you actually attacking me right now is exactly zero percent."

 

Bakugo’s jaw clenched so hard his teeth audibly ground together. Small sparks popped in his palms, but he didn't take another step. Izuku had trapped him in a cage of his own logic.

 

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

 

The voice came from the floor.

 

The entire class snapped their attention to the front of the room. A man resembling a giant yellow caterpillar was rolling around on the floor. A moment later, Shota Aizawa unzipped his sleeping bag and stood up, looking like a man who hadn't slept since the turn of the century.

 

Shota Aizawa. Pro Hero: Eraserhead, Izuku thought, his posture instantly straightening. He operates strictly in the underground. His presence as a homeroom teacher indicates U.A. is prioritizing combat pragmatism over media training this year.

 

"I am Shota Aizawa. Your homeroom teacher," the man drawled, pulling a blue gym uniform out of his sleeping bag. "It took you exactly eight seconds to quiet down. Time is a limited resource. You kids aren't rational enough."

 

Aizawa's tired eyes scanned the room, lingering on Izuku for a fraction of a second longer than the others. The gaze was cold, calculating, and deeply skeptical.

 

"Put these on," Aizawa commanded, tossing the gym uniform onto the front desk. "And head out to the P.E. grounds."

 

 

 

The sun beat down on the dirt track of the U.A. physical education grounds. The twenty students of Class 1-A stood in a loose cluster, wearing their blue and white tracksuits.

 

Izuku stood near the back, his hands resting calmly at his sides. He had removed his blazer and shirt to put on the tracksuit, but he had kept his modified shoes and his undersuit on. He had also swiftly attached the external pneumatic bracers over the sleeves of his gym uniform, locking the matte-black metal securely over his forearms.

 

Several students stared at the bulky, mechanical gauntlets.

 

"Hey, man," a red-haired boy with sharp teeth (Eijiro Kirishima) whispered. "Are we allowed to wear support items? I thought this was just a P.E. class."

 

"Principal Nezu granted me special dispensation under U.A. Bylaw 4-A," Izuku replied without looking at him. "My gear is permanently classified as my baseline operational capacity."

 

Aizawa stood at the front of the group, holding a digital tablet and a baseball.

 

"A Quirk Apprehension Test?" the class echoed in unison after Aizawa explained the agenda.

 

"What about the entrance ceremony? The orientation?" Uraraka asked nervously.

 

"If you're going to become a pro, you don't have time for leisurely events," Aizawa said coldly, his eyes sweeping the students. "U.A. is a 'freestyle' school. That means I run my class however I see fit. You've been doing these fitness tests since junior high, but always with your Quirks locked away. The Ministry of Education is procrastinating on adapting to reality. It's irrational."

 

Aizawa turned to Bakugo. "Bakugo, you finished first in the practical exam. What was your farthest softball throw in junior high?"

 

"Sixty-seven meters," Bakugo scoffed.

 

"Try it with your Quirk," Aizawa said, tossing him the ball. "Do whatever you want, just don't leave the circle."

 

Bakugo stepped into the chalk circle, a feral grin spreading across his face. He stretched his arms, rolled his shoulders, and wound up.

 

Biomechanics analysis, Izuku observed. He is utilizing a full-body rotational pivot to maximize kinetic transfer from his legs to his shoulder. He will initiate the explosion at the exact apex of the release to prevent the blast from counteracting his forward momentum.

 

"DIE!" Bakugo roared, violently throwing his arm forward.

 

A massive, concussive explosion erupted from his palm, the shockwave ruffling the hair of the students standing twenty feet away. The ball rocketed into the sky, leaving a trail of black smoke.

 

Aizawa held up his tablet, showing the screen to the class.

 

705.2 meters.

 

The class erupted.

"Over 700 meters? That's insane!"

"This looks like so much fun!"

"We can finally use our Quirks as much as we want!"

 

Aizawa's face darkened. The air around him suddenly felt heavy, dense, and suffocating.

 

"Fun?" Aizawa repeated softly. "You have three years to become heroes. Are you going to have an attitude like that the whole time?"

 

He smiled, a chilling, predatory expression that sent a shiver down the spines of the students. "Right. Whoever comes in last place in all eight tests will be judged to have no potential... and will be punished with immediate expulsion."

 

A collective gasp echoed across the field.

 

"You can't do that!" Uraraka cried. "It's the first day! Even if it wasn't, that's totally unfair!"

 

"Natural disasters, highway pileups, rampaging villains," Aizawa listed monotonously. "Calamity is always just around the corner. Japan is covered in unfairness. Heroes are the ones who reverse those situations. If you wanted to talk to your friends at McDonald's after school, too bad. For the next three years, U.A. will throw hardship after hardship at you. Go Plus Ultra. Overcome it."

 

Izuku analyzed Aizawa’s posture, his vocal cadence, and his micro-expressions.

 

Psychological manipulation, Izuku deduced immediately. Threatening expulsion artificially induces a high-stress environment, forcing students to bypass their natural psychological limiters. However, Aizawa's track record—which I cross-referenced on underground hero forums—shows he expelled an entire class of 154 students last year. The threat is not empty. He is a pragmatist. If he determines a student is a liability, he will remove them to prevent them from dying in the field.

 

Izuku looked down at his metallic gauntlets.

 

He is looking directly at me, Izuku realized. Eraserhead’s philosophy revolves around absolute self-reliance. He views technology as a crutch. If my gear fails in the field, I have no biological safety net. He wants to prove that I don't belong here.

 

Izuku tightened his fists. The internal pneumatics hummed softly in response.

 

Challenge accepted.

 

Test 1: 50-Meter Dash

 

The students lined up in pairs at the starting line. Iida easily cleared his heat in 3.04 seconds, his engine calves roaring. Tsuyu Asui clocked in at 5.58 seconds.

 

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

 

Bakugo stepped up to the line, glaring at Izuku. "I'm going to humiliate you, Deku. I'll show everyone that your little toys are garbage compared to a real Quirk."

 

Izuku didn't respond. He stepped up to the line. He didn't take a traditional sprinter's stance. Instead, he stood perfectly upright, his feet shoulder-width apart, knees slightly bent.

 

He reached down and tapped a small dial on the side of his right Vector Boot.

 

Adjusting kinetic spring tension to maximum linear output. Disengaging vertical shock absorbers. Vector angle: 15 degrees relative to the ground.

 

"Ready," the robotic camera at the finish line announced. "Get set."

 

BANG.

 

Bakugo immediately fired explosions behind him, launching himself forward like a human missile. "Burst Speed!" he yelled.

 

Izuku didn't run. He leaned forward until his center of gravity was past the point of no return, essentially falling toward the track. At the exact millisecond gravity took over, he triggered the compressed CO2 in his boots.

 

CRACK.

 

It sounded like a gunshot. The compressed gas fired into the kinetic springs, violently launching Izuku horizontally across the track. He didn't take steps; he essentially performed a low-altitude, high-velocity glide, using rapid, micro-bursts from the boots to sustain his forward momentum.

 

Because he wasn't running, he wasn't losing energy to the vertical oscillation of a natural human stride. He was a perfect, aerodynamic projectile.

 

He crossed the finish line in a blur of black and blue.

 

Robot voice: "3.12 seconds."

 

A microsecond later, Bakugo crossed.

 

Robot voice: "4.13 seconds."

 

Bakugo tumbled onto the dirt, completely flabbergasted. He looked back at the track, then at Izuku, who was calmly venting the excess steam from his boots.

 

"What... what the hell was that?!" Bakugo screamed, scrambling to his feet. "You didn't even run!"

 

"Running relies on muscular contraction, which is biologically limited by fast-twitch fiber density and lactic acid buildup," Izuku stated calmly, tapping his boots. "I bypassed the biological limitation by converting compressed gas into purely linear kinetic energy. It is basic physics, Bakugo. You lost energy because your explosions forced you to course-correct in mid-air to maintain a horizontal trajectory."

 

Bakugo looked like he was going to have an aneurysm.

 

Aizawa, standing on the sidelines, recorded the time on his tablet. His face was unreadable, but his eyes were narrowed tightly.

 

He bypassed the spirit of the test, Aizawa thought. But he achieved the objective. Let's see how he handles raw physical resistance.

 

Test 2: Grip Strength

 

The class moved to a set of digital dynamometers.

 

Mezo Shoji, the tall boy with multiple arms, casually squeezed his machine. 540 kg. The class gasped.

 

Izuku held his dynamometer in his right hand. The device was designed to measure biological muscle contraction. Izuku’s actual grip strength was roughly 45 kg—above average for a teenager who had cleaned a beach, but laughably pathetic in this company.

 

Izuku activated his right pneumatic bracer.

 

He didn't just squeeze. He linked the biometric sensors in his glove to the primary hydraulic actuator in the gauntlet. He took a deep breath, isolated the muscles in his forearm, and flexed.

 

The electrical impulse from his muscle triggered the actuator. The pneumatic piston inside the bracer fired, clamping Izuku’s metal-plated fingers down onto the dynamometer with the force of an industrial vice.

 

The machine let out a horrific screech of stressed metal. The digital numbers on the screen skyrocketed.

 

100... 300... 600... 850...

 

CRACK.

 

The dynamometer’s reinforced plastic handle shattered into pieces, the internal spring snapping violently.

 

Izuku released his grip, looking at the ruined machine in his hand. The screen flickered, frozen on the final number before catastrophic failure.

 

912 kg.

 

Silence reigned over the group.

 

"Uh," Kirishima muttered, his jaw practically touching the dirt. "Did he just break the machine?"

 

Izuku turned to Aizawa, his expression completely blank. "Apologies, Sensei. I failed to properly calibrate the pneumatic output to account for the tensile limits of U.A.'s testing equipment. I will reimburse the school for the damages."

 

Aizawa stared at the broken machine, then up at Izuku's calm face. He didn't use a Quirk. He used a hydraulic press strapped to his arm. The kid is literally a walking tank.

 

"Noted," Aizawa grunted, logging a maximum score for Izuku. "Move on to the next test."

 

Test 3 & 4: Standing Long Jump and Repeated Side Steps

 

For the long jump, Izuku simply recalibrated the Vector Boots for a 45-degree vertical launch, easily clearing the sandbox and landing softly on the grass beyond.

 

For the side steps, he faced a minor limitation. The boots were designed for linear thrust, not rapid lateral stabilization. Relying on them would cause him to snap his own ankles. So, he relied on his brain instead.

 

Izuku activated the HUD in his visor. He ran a predictive rhythmic algorithm, essentially generating a visual metronome that overlaid perfectly with his field of vision. He didn't think about his movements; he simply matched his biomechanics to the mathematical rhythm, eliminating all hesitation and wasted micro-movements. He scored in the upper 80th percentile, beaten only by Mineta’s bouncing balls and Iida’s engine.

 

As the tests progressed, the atmosphere in the class shifted. The initial mockery of the "Quirkless kid in the armor" had completely vanished. It was replaced by a creeping, undeniable sense of dread.

 

Izuku wasn't just passing. He was dominating. And he was doing it with a cold, robotic efficiency that made the students with actual superpowers feel deeply inadequate.

 

Test 5: The Softball Throw

 

This was the crucible.

 

Aizawa stood near the throwing circle, his eyes dark and heavy. Uraraka had just scored an infinity by removing the ball's gravity. Now, it was Izuku’s turn.

 

"Midoriya," Aizawa called out.

 

Izuku stepped into the circle. He held the standard U.A. softball in his left hand.

 

Aizawa watched him closely. This is it, the underground hero thought. He’s passed everything else using his gear. But throwing a ball requires a complex kinetic chain. If he sets the pneumatic pressure too high, the sudden torque will shatter his elbow. If he sets it too low, he fails. He is relying entirely on a piece of metal. If I take that away from him, he is nothing but a normal, fragile kid.

 

Aizawa believed in harsh truths. He believed that letting a Quirkless kid with a genius intellect play hero was equivalent to letting him commit suicide. Villains like Muscular or Venom wouldn't care about his math. If his gear broke, he would die. Aizawa decided he needed to break the kid now, before the villains could.

 

I will erase his 'Quirk', Aizawa decided. Even if it's technology, many support items require a baseline Quirk factor to operate biometrically, or at least rely on the user's enhanced biology to withstand the recoil. I will erase his Quirk factor. If his gear fails, I expel him. It’s for his own good.

 

In the circle, Izuku was completely still. His HUD was flooding his vision with environmental data.

 

Wind speed: 4 knots heading East. Humidity: 42%. Barometric pressure: 1013 hPa.

Object mass: 0.14 kg. Object surface friction coefficient: standard synthetic leather.

Objective: Maximum distance.

 

Izuku reached to his right bracer. He didn't just turn up the pressure; he altered the mechanics. He locked his elbow joint with the external titanium braces, turning his entire arm into a rigid fulcrum. He calculated the exact Magnus effect required to give the ball upward lift through backspin.

 

Pneumatic pressure: 1800 PSI. Release angle: 42 degrees.

 

Izuku took a deep breath. He stepped back, wound his arm, and prepared to throw.

 

On the sidelines, Aizawa’s eyes suddenly flared a brilliant, glowing red. His capture scarf defied gravity, floating up around his neck.

 

Erasure activated. Aizawa locked his gaze onto Izuku, nullifying the boy's Quirk factor, waiting for the suit to power down, waiting for the inevitable failure.

 

Izuku stepped forward. He triggered the gauntlet.

 

BOOM.

 

The sound was like a cannon going off. The pneumatic piston fired with such localized violence that the air around Izuku's arm visibly warped. The ball was ejected from his hand at supersonic speed.

 

It didn't just fly; it tore through the sky, ripping a visible trail through the air pressure before vanishing completely into the clouds.

 

Aizawa stood completely frozen. His eyes were still glowing red. His hair was still floating. His Quirk was fully active.

 

And the ball was gone.

 

Aizawa looked down at his digital tablet. It beeped, registering the GPS tracker inside the ball.

 

812.4 meters.

 

Aizawa’s eyes slowly deactivated, returning to their normal black. The scarf dropped back around his shoulders. He stared at Izuku, a profound sense of cognitive dissonance tearing through his mind.

 

My Quirk was active, Aizawa thought, his brain struggling to process the data. I was looking right at him. I erased his Quirk factor. But the gear... the gear still worked. The power output wasn't reduced at all.

 

Izuku stood in the circle, venting a massive cloud of steam from his right bracer to cool the internal pneumatics. He turned his head and looked directly into Aizawa’s eyes.

 

"You tried to erase my Quirk, didn't you, Sensei?" Izuku asked, his voice echoing across the silent field.

 

The entire class gasped. "Erase?" someone whispered.

 

Aizawa’s jaw tightened. "My Quirk nullifies the biological Quirk factor in a person's DNA. It shuts down the genetic mutation responsible for superhuman abilities." Aizawa took a step forward. "I looked right at you. But nothing happened. Your gear functioned perfectly."

 

"That is because you cannot erase what does not exist," Izuku said calmly.

 

He raised his right arm, tapping the metal plating of his gauntlet.

 

"I have no Quirk factor, Sensei. I am completely, genetically baseline. I do not possess a micro-telekinesis Quirk to guide my aim. I do not possess a technopathy Quirk to operate this suit. This armor runs purely on mechanical engineering, pneumatic pressure, and my own neurological electrical impulses."

 

Izuku took a step out of the circle, his green eyes boring into Aizawa’s soul.

 

"You look at me and see a liability," Izuku continued, his voice devoid of anger, stating it merely as a fact. "You assume that because my power comes from a workshop rather than a genetic lottery, it is inherently fragile. But biological Quirks are just as fragile, Sensei. A muscle can tear. A throat can go hoarse. Eyes can suffer from chronic dry eye syndrome, severely limiting combat effectiveness."

 

Aizawa flinched internally. Izuku had just perfectly analyzed his own Quirk's weakness without ever seeing him in a real fight.

 

"My gear might break," Izuku said, adjusting his collar. "But unlike a biological Quirk, I can repair my gear in a matter of hours. I can upgrade it. I can adapt it to specific villains. I am not limited by the DNA I was born with. I am only limited by the boundaries of physics, and I am very good at physics."

 

Izuku walked past Aizawa, the hydraulic servos in his boots whirring faintly.

 

"I scored 812.4 meters, Sensei," Izuku said softly. "Am I still a liability?"

 

For a long, agonizing moment, Aizawa said nothing. He looked at the boy's back. He looked at the crude, bulky, yet masterfully engineered metal strapped to his arms.

 

Aizawa had expelled hundreds of students for lacking potential. He had crushed dreams because those dreams lacked the foundation of reality. But looking at Izuku Midoriya, Aizawa realized something terrifying.

 

This boy didn't have a dream. He had a blueprint.

 

A small, genuine smile tugged at the corner of Aizawa’s mouth, hidden beneath his capture scarf.

 

You win, kid, Aizawa thought. You actually beat my logic.

 

"No," Aizawa said aloud, his voice returning to its normal, gruff tone. "You're not a liability. Get back in line."

 

Before Izuku could take another step, a scream of absolute, unhinged rage shattered the air.

 

"DEKU!"

 

Izuku turned just in time to see Katsuki Bakugo charging at him like a rabid animal. Bakugo’s eyes were bloodshot, his teeth bared in a snarl, explosions popping violently from both of his palms.

 

"TELL ME HOW YOU DID THAT!" Bakugo roared, completely abandoning all rational thought. "YOU'RE QUIRKLESS! YOU'RE A NOBODY! YOU CAN'T BEAT ME! I'LL KILL YOU!"

 

Bakugo lunged, his right hand pulled back, aiming a lethal explosion directly at Izuku’s face.

 

Threat imminent. Proximity: 2 meters. Response required.

 

Izuku didn't raise his gauntlets. He didn't activate his boots. He simply shifted his weight to his back foot, preparing to use Aikido to redirect Bakugo’s kinetic momentum and throw him face-first into the dirt.

 

But he didn't have to.

 

Before Bakugo could close the final distance, gray cloth shot through the air. Aizawa’s capture scarf wrapped securely around Bakugo’s torso and arms, pulling incredibly taut.

 

Bakugo hit the end of the scarf and was yanked backward, crashing onto the dirt.

 

"What the...?! This cloth is stiff!" Bakugo yelled, struggling against the bindings.

 

"It's a carbon-fiber weapon interwoven with metal wire," Aizawa said, his eyes glowing red once again, erasing Bakugo’s explosion Quirk. "Stand down, Bakugo. Or I will expel you right now for assaulting a fellow student."

 

Bakugo froze, the red fading from his palms. He looked at Aizawa, then over at Izuku.

 

Izuku was looking down at him. There was no fear in Izuku’s eyes. There wasn't even anger. There was only pity. The clinical, detached pity of a scientist looking at an animal that didn't understand it was trapped in a cage.

 

"Your behavioral patterns are entirely predictable, Bakugo," Izuku said quietly. "You rely on intimidation and raw power to establish dominance. When faced with a variable you cannot overpower, your psychological defense mechanism triggers an aggressive panic response. It is a severe tactical weakness."

 

Izuku turned away. "If a villain figures that out, they will bait you into a trap and kill you within seconds. You need to fix that."

 

Bakugo lay in the dirt, his mind short-circuiting. The world he understood—a world where the strong dominated the weak, where his Quirk made him a god, where Deku was just a pebble on the side of the road—was crumbling around him.

 

Aizawa released the scarf. "Test is over. I'm projecting the results now."

 

Aizawa tapped his tablet, projecting a holographic leaderboard.

 

Izuku analyzed the rankings.

 

1. Momo Yaoyorozu

2. Shoto Todoroki

3. Katsuki Bakugo

4. Izuku Midoriya

5. Tenya Iida

 

Izuku nodded to himself. Fourth place. A statistically optimal outcome. He had proved his capabilities without revealing the full extent of his tactical arsenal, and he had secured a comfortable position above the median.

 

"By the way, I was lying about the expulsion," Aizawa announced casually, turning off the projection.

 

The class froze.

 

"It was a rational deception to draw out the upper limits of your Quirks," Aizawa smiled creepily.

 

"WHAT?!" half the class shrieked.

 

"Of course it was a lie," Yaoyorozu sighed, rubbing her temples. "It should have been obvious if you just thought it through."

 

It wasn't a lie, Izuku thought, exchanging a brief, knowing glance with Aizawa. If I had failed to justify my presence here, he would have expelled me without hesitation. The 'rational deception' is merely a post-hoc excuse to preserve his authority after realizing he miscalculated.

 

"We're done here," Aizawa said, turning his back on the class. "There are handouts with the syllabus back in the classroom. Midoriya."

 

Izuku paused, turning back to the teacher.

 

"Sir?"

 

"Your pneumatic bracers," Aizawa said, not looking back. "The acoustic signature of the pressure release is too loud. It gives away your position three seconds before you fire. If you're going to rely on that junk, install a sonic dampener. I won't have my students getting ambushed because their toys squeak."

 

Izuku’s eyes widened slightly in genuine surprise. It was the first piece of constructive feedback he had received from an authority figure in his entire life. It wasn't pity. It wasn't mockery. It was a tactical assessment.

 

"Understood, Sensei," Izuku bowed slightly. "I will draft the blueprints tonight."

 

As Izuku walked back toward the locker rooms, leaving a bewildered and terrified Class 1-A behind him, Shota Aizawa watched him go.

 

He is entirely Quirkless, Aizawa mused, burying his face back into his capture scarf. No enhanced strength. No speed. No genetic safety net. Just a terrifyingly brilliant brain and a terrifyingly sheer force of will.

 

Aizawa couldn't help but smirk in the quiet of the empty field.

 

The League of Villains won't know what hit them.
