What If Deku Invented Cyberware To Compete With Quirks

 

 

 

 

The world, Izuku Midoriya had learned at the tender age of four, was not created equal.

 

It was a lesson etched into his bones, hammered into his psyche by the mocking laughter of his peers, and scarred into his skin by the popping, blistering heat of Katsuki Bakugo’s explosions. Society was a genetic lottery, a grand casino where eighty percent of humanity had won the jackpot, leaving the remaining twenty percent to scavenge for the scraps.

 

Izuku was one of the scavengers. A Quirkless anomaly in a world of gods and monsters.

 

Yet, he had never stopped looking up at the sky. He had never stopped believing that if he just reached high enough, tried hard enough, and smiled through the pain, he could stand among them. He wanted to be a hero. He wanted to be like All Might.

 

That naive, desperate dream died on a Tuesday afternoon, under the suffocating, foul-smelling embrace of a sentient sewer.

 

The sludge villain had struck without warning. One moment, Izuku had been walking through an underpass, his head bowed, clutching his scorched Hero Analysis for the Future, No. 13 notebook to his chest. The next, a shadow had peeled itself from the concrete, rising like a tidal wave of liquid rot.

 

"A medium-sized invisibility cloak," the villain had gurgled, its voice a wet, wretched sound that vibrated against Izuku’s eardrums. "Perfect."

 

When the sludge forced its way down Izuku’s throat, the sensory overload was absolute. It tasted like rust, stagnant water, and decay. The sheer hydrostatic pressure of the villain's body crushed against his ribs, pinning his arms, locking his knees. Izuku thrashed, his fingernails clawing uselessly at the viscous mass. He couldn't breathe. His lungs screamed for oxygen, burning with the fiery, acidic agony of asphyxiation.

 

I’m going to die, Izuku thought, his vision fracturing into black spots. I’m going to die here, and no one will even know.

 

Even as his consciousness faded, his analytical mind—the only weapon he had ever possessed—ran a frantic diagnostic on the creature. Fluid-based heteromorph. High surface tension. Viscosity shifts based on intent. Core weakness must be the eyes or mouth, the only solid constructs in the mass. But that knowledge was useless. He had no leverage, no strength, no Quirk to exploit the weakness.

 

Then, the manhole cover blew off.

 

A colossal silhouette filled the underpass, radiating a golden, blinding light. The air pressure in the tunnel shifted violently.

 

"Fear not, kid!" a voice boomed, echoing with impossible resonance. "I am here!"

 

The Texas Smash wasn't just a punch; it was a localized hurricane. Izuku felt the wind shear rip the sludge from his throat and eyes. The villain didn't just break apart; it atomized, scattering into countless harmless droplets against the concrete walls. Izuku collapsed, coughing up vile fluid, gasping for the sweet, cold air. The last thing he saw before the world faded to black was the towering, muscular form of the Symbol of Peace.

 

 

 

When Izuku awoke, the afternoon sun was stinging his eyes. He jolted upright, his hands flying to his throat, expecting the sludge. Instead, he felt the gentle breeze of the city. He was safe.

 

And All Might was standing right in front of him.

 

The events that followed felt like a fever dream. The frantic bowing, the discovery of the legendary hero's autograph spanning two pages of his ruined notebook, the overwhelming awe of being in the presence of his idol. All Might was packing the unconscious villain into two empty soda bottles, preparing to leave.

 

"Well, I must be off!" All Might declared, his smile radiant. "Pro heroes are constantly fighting time as well as enemies!"

 

Wait, Izuku's mind screamed. No, you can't leave yet. I have to ask you. I have to know.

 

The desperation took over. It bypassed his common sense, his anxiety, and his self-preservation. As All Might bent his knees to jump, Izuku lunged. He grabbed onto the hero's massive, denim-clad leg just as the man launched himself into the stratosphere.

 

The G-force nearly ripped Izuku's arms from their sockets. The wind roared in his ears, a deafening tornado that flattened his cheeks and tore tears from his eyes. Below him, the sprawling metropolis of Musutafu shrank into a grid of tiny, insignificant blocks.

 

"Hey, hey, hey! What do you think you're doing?!" All Might shouted over the wind, frantically trying to peel the boy off. "Release me! Your fanaticism is too much!"

 

"If I let go now, I'll die!" Izuku screamed back, his voice cracking, his eyes squeezed shut.

 

Realizing the boy was right, All Might sighed, adjusting his trajectory. They landed with a heavy, building-shaking thud on the roof of a towering commercial complex.

 

Izuku collapsed onto the sun-baked concrete, his legs turning to jelly, his heart hammering against his ribs like a trapped bird. He gasped for air, his whole body trembling. He had done it. He had cornered the Symbol of Peace. This was his chance. The question that had haunted him since he was four years old, the question that had earned him beatings, mockery, and the pitying tears of his own mother, was finally going to be answered by the ultimate authority.

 

"That was dangerous," All Might scolded, wiping a bead of sweat from his forehead. "Now, go downstairs and knock on the door. Someone will let you out. I have to go."

 

"Wait!" Izuku scrambled to his feet, reaching a hand out. "Please! Just one question!"

 

All Might paused, his back turned to the boy.

 

Izuku swallowed the lump in his throat. His hands clenched into tight fists at his sides. "People... people think I don't have a chance because I don't have a Quirk." The words tumbled out, rushed and desperate. "They say I'm useless. A Deku. But I've always wanted to save people. I want to save people with a fearless smile, just like you! So... tell me..."

 

He squeezed his eyes shut, bracing for the impact.

 

"Can a Quirkless person be a hero like you?!"

 

Silence fell over the rooftop. For a long, agonizing moment, the only sound was the distant hum of traffic far below. Izuku opened his eyes, waiting for the booming laugh, the reassurance, the validation he had spent a decade craving.

 

Instead, a thick cloud of steam exploded from All Might's body.

 

Izuku stumbled back, coughing as the vapor enveloped the hero. When the steam cleared, the towering, mountain-like figure of the Symbol of Peace was gone. In his place stood an emaciated, skeletal man. His clothes hung loosely off a frame of sharp angles and hollowed cheeks. His eyes were deeply sunken, glowing with a dim, weary blue light. Blood trickled from his chin.

 

"W-What?" Izuku stammered, his mind short-circuiting. "An imposter? A fake? Where is All Might?!"

 

"I am All Might," the skeletal man sighed, wiping the blood from his mouth with a bony thumb. He sank against the rooftop railing, sliding down until he was sitting on the concrete. He pulled up his oversized t-shirt, revealing a horrific, jagged scar that engulfed the entire left side of his chest. It looked like a crater, a web of mangled, purple flesh that made Izuku’s stomach churn.

 

"Five years ago," All Might said, his voice raspy and devoid of its usual booming confidence. "An enemy did this to me. My respiratory system was nearly destroyed. I lost my whole stomach. All the surgeries have worn me down. Right now, I can only do hero work for about three hours a day."

 

Izuku stared, paralyzed. The invincible god of his childhood was mortal. He was broken.

 

"Why... why are you showing me this?" Izuku whispered.

 

All Might looked out over the city skyline, his expression incredibly old and unbearably tired. "Because you asked a question, kid. And you need the truth. There's plenty of fear and danger behind that smile I wear. I smile to trick the fear inside me, and to trick the people into feeling safe. Pro heroes are always risking their lives. Some villains just can't be beaten without power."

 

The words hung in the air, cold and heavy.

 

"So, no," All Might said softly, looking directly into Izuku's wide, tear-filled eyes. "I honestly don't think you can become a hero without a Quirk."

 

The world stopped spinning. The air left Izuku's lungs, not forcefully like with the sludge villain, but quietly, as if his soul was deflating.

 

"If you want to help people," All Might continued, his tone shifting to one of gentle pragmatism, "become a police officer. They get mocked because the heroes handle the villains, but it's a fine profession. It's not bad to dream, kid. But you have to be realistic."

 

All Might stood up, his skeletal frame casting a long, thin shadow over Izuku. He walked toward the rooftop door, opened it, and disappeared into the stairwell. The heavy metal door clicked shut, the sound echoing with finality.

 

Izuku stood alone on the rooftop.

 

He didn't cry. He was too hollow to cry. The core pillar of his existence—the belief that his hard work and heroic heart would eventually be recognized—had just been pulverized into dust by the very man who inspired it. The verdict was in. The highest court had ruled.

 

You cannot be a hero.

 

 

 

The walk home was a blur of gray concrete and muted sounds. Izuku's feet moved automatically, carrying his numb body through the familiar streets of Musutafu.

 

At one point, he heard the booming sound of explosions. He saw smoke rising in the distance. A crowd had gathered near Tatooin Shopping District. Sirens wailed. In the past, Izuku would have sprinted toward the commotion, notebook in hand, eager to analyze the heroes' tactics and Quirk applications.

 

Today, he stopped at the edge of the alleyway, looking at the distant smoke. He heard the faint, angry roars of a teenager. He heard the gasps of the crowd. But his legs refused to move forward.

 

What's the point? he thought, his eyes dull. I can't do anything. I'm just a bystander. A Quirkless Deku.

 

He turned his back on the smoke and took the long way home. He didn't know it then, but Katsuki Bakugo was suffocating in the grip of the very same sludge villain Izuku had encountered. He didn't know that the heroes were standing around, paralyzed by incompatible Quirks. He didn't know that by walking away, he was missing a moment of supreme irony.

 

He just knew he was empty.

 

When he finally unlocked the door to his apartment, the smell of his mother’s cooking—katsudon, his favorite—wafted into the hallway.

 

"Izuku? Is that you, sweetie?" Inko Midoriya called out from the kitchen.

 

"Yeah, Mom. I'm home," Izuku replied. To his own ears, his voice sounded like it belonged to a dead man.

 

"Dinner is almost ready! How was school?"

 

"Fine. I'm... I'm going to my room to study."

 

Before she could step out to greet him, Izuku slipped into his bedroom and shut the door. He locked it. He didn't turn on the light.

 

The fading twilight bled through the window blinds, casting long, barred shadows across the room. Every inch of his bedroom was a shrine to All Might. Action figures in heroic poses lined the shelves. Posters plastered the walls, showing the hero in various states of triumph, his blinding smile beaming down. Bed sheets, alarm clocks, replica capes. A monument to a lie.

 

Izuku walked to the center of the room and dropped his yellow backpack onto the floor. It landed with a dull thud. He stood there for a long time, staring at a life-sized poster of All Might’s Silver Age debut.

 

“It’s not bad to dream, kid. But you have to be realistic.”

 

The words echoed in his skull. Realistic. What did realistic mean? It meant accepting the biological hierarchy. It meant accepting that because he lacked an extra joint in his pinky toe, because his DNA lacked the specific metaphysical mutation required to generate fire, or telekinesis, or super strength, he was biologically inferior.

 

Izuku walked over to his desk. His hands were shaking. He unzipped his backpack and pulled out the burnt, water-logged notebook. Hero Analysis for the Future, No. 13. Bakugo had blown it up and tossed it into a koi pond earlier that day.

 

Izuku opened it. The pages were crinkled, the ink smudged, but the data was still legible.

 

He flipped back a few pages, looking at his notes on Mt. Lady. She had debuted that morning. His notes were meticulous. He hadn't just drawn her costume; he had calculated her mass.

 

Mt. Lady. Quirk: Gigantification.

Estimated height: 2062 cm. Estimated weight at full size: based on the square-cube law, if her baseline weight is 60 kg, scaling up by a factor of 12.7 means her weight should increase by a factor of 2,048. She should weigh over 122,000 kg (122 metric tons).

Biological mechanics: How do her bones not shatter under that weight? Her skeletal density must exponentially increase upon activation. Her circulatory system must generate immense hydrostatic pressure to pump blood to her brain.

 

Izuku stared at his own handwriting. He blinked.

 

He reached into his bottom drawer and pulled out a stack of older notebooks. He grabbed Notebook No. 7 and flipped it open to a page dedicated to Katsuki Bakugo.

 

Katsuki Bakugo. Quirk: Explosion.

Biological mechanics: Sweat glands in palms secrete a nitroglycerin-like substance. Spark is ignited by microscopic friction in the epidermis. Nitroglycerin is highly unstable. To survive his own blasts, his arms must possess hyper-dense muscle fibers and reinforced joints to absorb the kinetic recoil.

 

He grabbed another notebook. Notebook No. 9. Tenya Iida, a famous middle schooler from a wealthy hero family.

 

Tenya Iida. Quirk: Engine.

Biological mechanics: Calves possess biological exhaust pipes. The body functions like an internal combustion engine. Requires organic fuel (sugar/orange juice). The leg bones must be laced with a metallic alloy to withstand the heat of combustion.

 

Izuku dropped the notebooks onto his desk. He took a step back, his breath hitching.

 

For ten years, he had been doing this. He had been obsessively deconstructing the magic of Quirks and reducing them to their base components: biology, chemistry, and physics. To everyone else, a Quirk was a superpower, a mystic blessing of genetics. But to Izuku Midoriya, whose only way to interact with Quirks was to study them from afar, they had never been magic.

 

They were machines.

 

Biological machines, yes. Flesh, blood, and bone engineered by evolution to perform specific, reality-bending tasks. But machines nonetheless.

 

"Gigantification..." Izuku whispered into the quiet room. "It's just pneumatic expansion and structural reinforcement."

 

He looked at Bakugo's page. "Explosion... it's just chemical synthesis and kinetic recoil."

 

He looked at Iida's page. "Engine... it's literally just an engine."

 

A strange, cold feeling began to spread outward from Izuku's chest. It wasn't the fiery passion of his childhood dreams, nor was it the suffocating despair of the rooftop. It was something entirely new. It was clarity. A sharp, piercing, almost terrifying clarity.

 

If a Quirk is just a biological mechanism, Izuku thought, his heart beginning to beat faster, if it operates on the laws of physics and chemistry... then it can be replicated.

 

Evolution had spent two hundred years turning humans into biological weapons. But humanity had spent ten thousand years mastering tools. Why rely on the genetic lottery to give you an engine in your legs, when you could build one?

 

Why beg for a Quirk, when you could manufacture one?

 

"Realistic," Izuku muttered, a slow, unhinged smile creeping onto his face. The tears that had been threatening to fall evaporated, replaced by a burning, obsessive light in his emerald eyes. "He told me to be realistic."

 

Izuku turned to look at the massive All Might poster on his wall. He didn't see the Symbol of Peace anymore. He saw a man with a ruined respiratory system and a destroyed stomach. He saw failing biology. Flesh was weak. Flesh could be smashed, burned, and deteriorated by time.

 

Izuku walked over to the poster. He reached up, grabbed the edge, and ripped it down.

 

He moved methodically around the room. He tore down the posters. He packed the action figures into cardboard boxes. He folded the replica capes and stuffed them under his bed. Within an hour, his room was stripped of its childhood hero worship. It was no longer a shrine to All Might. It was a blank canvas.

 

He returned to his desk. He shoved the ruined Notebook No. 13 into the trash can. He didn't need it anymore. He reached into his drawer and pulled out a fresh, unblemished notebook with a sleek black cover.

 

He grabbed a pen, clicked it, and stared at the blank first page.

 

For a moment, he hesitated. The path he was about to walk down was not the path of the smiling, shining hero in the sunlight. It was the path of oil, grease, burnt copper, and late nights. It was the path of a mad scientist, an engineer attempting to bridge the gap between gods and mortals with steel and wire. If society deemed him a Quirkless reject, then he would reject the society that worshipped Quirks. He would show them the power of a human mind.

 

Izuku pressed the pen to the paper.

 

At the top of the page, he wrote:

 

PROJECT: OVERDRIVE.

Sub-Directive 01: Artificial Enhancement and Cybernetic Augmentation.

 

Below that, he began to draw. Not heroes in spandex, but schematics. He drew an arm, stripping away the skin to reveal the muscles, and then replaced the muscles with braided synthetic fibers. He drew a skeletal forearm and wrapped it in a hydraulic brace. He began calculating the torque required to replicate the impact of a low-level enhancement Quirk.

 

His mind, freed from the chains of wishing for a miracle, began to process information at a terrifying speed. He realized he didn't just need armor. Armor could be broken. Armor was external. If he wore a suit, he was just a boy in a suit.

 

No, to compete with biology, the machine had to become biology. It had to be integrated. Cyberware. Biomechanics. Neural interfaces that connected directly to the motor cortex so that moving a steel fist felt as natural as moving a flesh one.

 

He wrote down materials. Carbon fiber. Titanium alloys. Pneumatic pistons. High-density battery cells. Micro-processors. Myoelectric sensors.

 

I have ten months until the UA Entrance Exam, Izuku calculated. Ten months to turn my body into a weapon.

 

There was only one problem. He was a fourteen-year-old middle schooler. He had no money, no lab, and no resources. A high-density servo motor could cost hundreds of thousands of yen. Medical-grade titanium was restricted. If he asked his mother to buy him machinery, she would think he was losing his mind.

 

He needed a supply of raw, untraceable materials. He needed a place where technology went to die.

 

Izuku paused his pen. His eyes darted to the window. In the distance, illuminated by the city lights, he could just barely see the coastline.

 

Takoba Municipal Beach.

 

For years, the beach had been an illegal dumping ground. Because the ocean currents naturally washed trash ashore, the locals had given up on it, using the sandy expanse to dump broken appliances, totaled cars, junked industrial machinery, and discarded electronics. It was a mountain range of forgotten technology. To the city, it was an eyesore.

 

To Izuku Midoriya, it was a gold mine.

 

 

 

The next morning, a Saturday, the sun rose over Takoba Municipal Beach to reveal a landscape of absolute desolation.

 

Mountains of rusted refrigerators, crushed cars, shattered washing machines, and tangled heaps of industrial cables stretched as far as the eye could see. The salty breeze of the ocean was masked by the smell of stagnant water and decaying iron. Seagulls picked at the garbage, the only signs of life in the metallic wasteland.

 

At 6:00 AM, Izuku Midoriya stood at the edge of the sea wall, looking down at the trash.

 

He was wearing a pair of heavy canvas work pants, a stained gray t-shirt, thick rubber gloves, and a pair of industrial goggles he had bought with his allowance. In his right hand, he held a heavy steel crowbar. In his left, a large canvas duffel bag.

 

He didn't look at the beach with disgust. He looked at it the way a master sculptor looks at a block of rough marble.

 

Izuku climbed down the stone steps and stepped onto the sand. He walked purposefully toward a massive, crushed pickup truck that had been dumped near the shoreline. The front end was completely caved in, but Izuku wasn't interested in the engine block. He was interested in the suspension.

 

He knelt down, wedged the crowbar under the wheel well, and began to pry at the rusted chassis. His scrawny arms shook with the effort. He gritted his teeth, planting his boots into the sand, and heaved with all his meager body weight. With a loud, protesting screech of tearing metal, the panel snapped off.

 

Izuku reached inside, his gloved hands navigating the sharp, jagged edges of the frame. He found what he was looking for: a heavy-duty hydraulic shock absorber. It was coated in grime, but the primary cylinder looked intact.

 

"Perfect," Izuku muttered, wiping sweat from his brow. He tossed the heavy metal cylinder into his duffel bag.

 

He spent the next five hours crawling through the metallic labyrinth of Takoba. He was meticulous in his scavenging. He wasn't just grabbing random junk; his mind was a checklist of components for Project: Overdrive.

 

From a shattered line of arcade cabinets, he extracted miles of copper wiring and pristine micro-controllers. From a discarded construction crane's control cabin, he scavenged high-torque rotary servos and a heavy-duty battery array. He found a graveyard of old smart-appliances, ripping out the motherboards to harvest their processing chips.

 

By noon, his duffel bag was so heavy he could barely drag it across the sand. His muscles screamed in protest, his hands were blistered beneath his gloves, and his face was smeared with black grease and dirt. But he had never felt more alive. Every ache in his body was a step toward his goal.

 

As he dragged the bag toward the edge of the beach, he realized he had another problem. He couldn't take this home. His mother would definitely notice if he started hoarding industrial machinery and car parts in his bedroom. Furthermore, he couldn't build, weld, or solder in an apartment without setting off the fire alarms or burning the place down.

 

He needed a base of operations.

 

Izuku surveyed the sprawling junkyard. His eyes scanned the towering piles of refuse. Near the eastern edge of the beach, half-buried under a collapsed pile of rusted scaffolding, he spotted something promising.

 

It was a large, corrugated steel shipping container. It was painted a faded, chipping seafoam green, and it looked like it had washed ashore years ago and been subsequently buried by subsequent dumpings. The heavy steel doors were shut tight, locked by a rusted padlock.

 

Izuku dropped his bag and approached the container. He tapped the side with his crowbar. It sounded hollow, meaning it wasn't packed with trash.

 

He moved to the doors, wedged the crowbar into the loop of the rusted padlock, and threw his weight against it. The lock, weakened by years of saltwater corrosion, gave way with a sharp snap. Izuku pulled the heavy metal doors open. They shrieked on their hinges, protesting the movement.

 

Sunlight pierced the gloom of the container's interior. It was completely empty, save for a thick layer of dust and a few dried-out crab shells. It was roughly twenty feet long and eight feet wide. The steel walls were thick enough to muffle sound, and it was hidden from the street view by the surrounding mountains of garbage.

 

"My laboratory," Izuku breathed, a massive grin splitting his soot-stained face.

 

The rest of the weekend was a blur of exhausting, back-breaking labor. Izuku spent Saturday afternoon sweeping out the container, patching a small leak in the roof with scrap sheet metal and waterproof sealant he found in a discarded toolbox.

 

On Sunday, he began building his workspace. He found a heavy oak dining table with two broken legs, sawed them off to make it level, and braced it against the wall to serve as a workbench. He scrounged for every usable tool on the beach: rusty wrenches, screwdrivers, a surprisingly intact soldering iron, half a roll of duct tape, and an old, gasoline-powered portable generator that he managed to fix after three hours of cleaning the carburetor.

 

When he finally pulled the cord on the generator, the machine sputtered, coughed, and roared to life. He plugged in a salvaged desk lamp. A harsh, bright halogen light flooded the shipping container, illuminating his workbench.

 

Izuku sat on a cracked plastic crate in front of the bench, looking at the pile of scavenged parts before him.

 

He opened his black notebook to page two. Prototype 01: Exomuscular Grip Enhancer.

 

Before he could build a neural interface or integrate cyberware into his flesh, he needed to prove the concept. He needed to prove that he, a Quirkless fourteen-year-old, could build a machine that amplified human biology.

 

He picked up a heavy leather workman's glove he had found. Next, he took the copper wire, a small battery pack, and a series of linear actuators he had stripped from the power-windows of a junked sedan.

 

He went to work.

 

Time lost its meaning in the shipping container. Izuku was in a state of absolute flow. His hands, though inexperienced, moved with the precision of a surgeon guided by his obsessive, analytical mind. He measured, cut, and soldered. He laced the back of the leather glove with the copper wiring, creating a crude myoelectric sensor network that would detect the electrical impulses of his forearm muscles.

 

He attached the small linear actuators to the knuckles and fingers of the glove, linking them to a central servo-motor mounted on a crude metal bracer that wrapped around his wrist. He wired the entire system to the battery pack, which he strapped to his forearm.

 

It was ugly. It was a Frankenstein's monster of leather, exposed wires, duct tape, and salvaged car parts. It looked heavy, dangerous, and highly unstable.

 

It was perfect.

 

The sun had long since set, and the only light in the container was the harsh glare of the desk lamp. Izuku held his breath as he carefully slipped his right hand into the heavily modified glove. He tightened the leather straps around his forearm, securing the battery pack and the servo-motor.

 

The device weighed nearly five pounds, dragging his arm down.

 

Izuku looked at the workbench. He grabbed an empty, thick-glassed Coca-Cola bottle he had found on the beach and placed it in the center of the table.

 

He reached over to the battery pack with his left hand and flipped the small toggle switch.

 

The glove hummed. It was a low, vibrating sound, like a hornet trapped in a tin can. A tiny green LED light on the wrist bracer flickered to life. The myoelectric sensors were active.

 

Izuku took a deep breath. He held his right hand out, hovering it over the glass bottle. He didn't move his fingers yet. He just stared at the mechanical monstrosity strapped to his flesh.

 

If this fails, he thought, then I am truly powerless. Then I am just a Deku playing with garbage.

 

He closed his eyes. He pictured the sludge villain. He pictured All Might's skeletal face, telling him to give up. He pictured Bakugo's sneer, the explosions popping in his palms.

 

He opened his eyes. They were cold, emerald shards.

 

Izuku squeezed his hand into a fist.

 

The myoelectric sensors detected the electrical firing of his forearm muscles. They sent a signal to the micro-controller. The micro-controller flooded the servo-motor with power. The linear actuators on the knuckles snapped shut with brutal, hydraulic force.

 

Izuku's fingers slammed into the glass bottle. He barely felt any resistance. He didn't even have to squeeze hard; the machine did the work for him.

 

CRACK.

 

The thick glass bottle exploded into a hundred pieces. Shards rained down onto the wooden workbench, glittering under the halogen light.

 

Izuku froze. He slowly opened his hand. The actuators whirred, pulling his fingers back with a mechanical hiss. He looked at the crushed remains of the bottle, and then down at the mechanical glove. There was not a single scratch on his hand. The machine had taken the kinetic impact.

 

He had just exerted a grip strength of roughly four hundred pounds per square inch. Far beyond the capacity of a normal human. A minor strength-enhancement Quirk, replicated entirely from a junked car and an arcade machine.

 

Izuku Midoriya stared at his metal-clad hand, the hum of the servo-motor vibrating through his bones. The sound was intoxicating. It was the sound of power. It was the sound of defiance.

 

A shadow shifted in the corner of his eye. He looked up, his reflection caught in a jagged piece of a broken mirror resting against the container wall.

 

He didn't see a helpless victim. He didn't see a boy crying on a rooftop. He saw a boy with grease on his face, wild, unkempt green hair, and a crude, mechanical gauntlet that radiated quiet, violent potential.

 

"Flesh is weak," Izuku whispered into the silence of the steel box. He flexed the mechanical fingers again. Whir-clack.

 

"But iron... iron is forever."

 

Izuku reached over, turned off the generator, and plunged the shipping container into darkness. The age of the Quirkless Deku was over.

 

Project Overdrive had begun.

 

 

 

 

 

The transition from a boy who dreamed of heroes to a boy who built them was not instantaneous. It was measured in scraped knuckles, burnt fingertips, and the bitter, metallic taste of ozone that permanently lingered in the back of Izuku Midoriya’s throat.

 

The first three months of the ten-month window before the U.A. Entrance Exam were an exercise in frustrating, agonizing trial and error.

 

Izuku’s shipping container at Takoba Municipal Beach had evolved from a hollow steel box into a claustrophobic, high-tech sanctuary. The walls were plastered with complex schematics, mathematical equations, and anatomical diagrams of the human nervous system. Stacks of salvaged hard drives, tangled mounds of copper wiring, and disassembled car batteries formed a miniature skyline across the rusted floor.

 

His initial approach to Project OVERDRIVE had been strictly external. He spent weeks designing and welding a full-body exoskeleton. It was a bulky, skeletal frame made of scavenged aluminum tubing and driven by pneumatic pistons ripped from the landing gear of a discarded private helicopter. It was strapped over his clothes using heavy-duty nylon belts.

 

On paper, it worked. The myoelectric sensors taped to his skin picked up the electrical impulses of his muscles, translated them into code, and commanded the pneumatic pistons to fire.

 

In practice, it was a death trap.

 

Izuku stood in the center of the junkyard, rain pouring down his face, wearing the Mark I Exoskeleton. He stared at a towering pile of crushed sedans.

 

"Activating kinetic sequence," Izuku muttered to himself, his breath pluming in the cold November air.

 

He threw a punch.

 

First, his biological arm moved. A fraction of a second later, the myoelectric sensors registered the muscle contraction. Another fraction of a second passed as the micro-controller processed the signal. Finally, the pneumatic piston fired, driving the aluminum brace forward.

 

The punch collided with the door of a rusted Toyota. The metal buckled inward with a satisfying crunch, the force equivalent to a sledgehammer swinging at sixty miles per hour.

 

But Izuku didn't smile. He hissed in pain, clutching his shoulder.

 

Latency.

 

It was the great enemy of engineering. The delay between the command and the execution. In the world of video games, a latency of two hundred milliseconds was an annoyance. In the world of Pro Hero combat, where villains with speed-enhancing Quirks moved at the speed of sound, a two-hundred-millisecond delay was a death sentence.

 

Because the exoskeleton moved after Izuku moved, his biological arm was constantly fighting the machine. He was throwing the punch, and then the machine was violently dragging his arm the rest of the way. It was tearing at his rotator cuff, straining his tendons, and bruising his skin.

 

Izuku walked back to the shipping container, drenched and shivering. He unbuckled the exoskeleton, letting the heavy metal frame clatter to the floor. He sat in his rolling desk chair, staring at his computer monitor.

 

"External sensors aren't enough," he whispered, rubbing his aching shoulder. "Skin is an insulator. It muffles the electrical signals from the brain. By the time the machine reads the muscle twitch, it’s already too late. A Quirk doesn't have latency. A Quirk activates at the exact speed of thought because it's biologically hardwired into the central nervous system."

 

He pulled up a medical textbook PDF on his screen. He scrolled past skeletal structures and muscular diagrams, stopping on a highly detailed rendering of the human spinal cord.

 

The spinal cord. The superhighway of the human body. Millions of neurons firing microscopic electrical charges, carrying raw, unfiltered data straight from the motor cortex to the limbs.

 

Izuku’s eyes widened, reflecting the harsh blue light of the monitor.

 

"If I want the machine to move at the speed of thought... it can't read my muscles." He leaned closer to the screen, his heart rate accelerating. "It has to read my mind."

 

He grabbed his black notebook and flipped to a fresh page. His pen flew across the paper, sketching a device that looked less like a machine part and more like a metallic centipede.

 

He called it the Neural-Spine Interface, or NSI.

 

The concept was terrifyingly simple, yet functionally insane. Instead of wearing a suit that guessed his movements, he would surgically implant a titanium data-tap directly into his lower cervical vertebrae. The NSI would feature microscopic, conductive filaments that would pierce the spinal dura mater and wrap around the nerve bundles.

 

When his brain sent the command ‘move arm,’ the NSI would intercept the raw electrical signal before it even reached his biological muscles, transmitting it instantly to external cybernetic limbs via a subcutaneous port.

 

Zero latency. The machine would not be an extension of his body. It would be his body.

 

The realization brought a cold sweat to Izuku's brow. To do this, he would have to cut into his own flesh. He would have to drill into his own spine. One millimeter off, one severed nerve, and he would be permanently paralyzed from the neck down.

 

He looked at his hands. They were calloused, scarred, and stained with grease. They were the hands of a Quirkless nobody.

 

"Biology failed me," Izuku said aloud, his voice steadying in the empty container. "It's time for an upgrade."

 

 

 

The fourth month of his preparation was the darkest.

 

Izuku didn't build weapons. He built a surgical theater. He spent weeks scouring the deeper, more dangerous parts of the junkyard, salvaging components from discarded medical imaging machines and high-precision manufacturing robotics.

 

He constructed an automated surgical rig directly above a sanitized, plastic-wrapped examination table in his container. It consisted of three articulated robotic arms equipped with scalpel attachments, a high-speed micro-drill, and a cauterizing laser. He programmed the rig using an old laptop, feeding it thousands of 3D topological scans of his own back, mapping the exact coordinates of his C7 and T1 vertebrae.

 

The NSI itself took three weeks to fabricate. It was a beautiful, horrifying piece of technology. A three-inch strip of salvaged surgical steel, housing a micro-processor salvaged from a military-grade drone. Protruding from its underside were dozens of hair-thin platinum wires designed to interface with his spinal cord.

 

The night of the operation, a fierce winter storm battered the coast of Musutafu. The wind howled against the corrugated steel of the shipping container, rattling the walls.

 

Izuku stood shirtless in the freezing container, trembling. He had scrubbed his skin with industrial-grade iodine until it was raw and burning. On a tray beside the operating table sat a syringe filled with lidocaine, procured from a sketchy online pharmacy using a prepaid debit card, and a bottle of high-proof vodka.

 

He took a swig of the vodka, coughing violently as the alcohol burned its way down his throat. It didn't calm his nerves, but it warmed his freezing blood.

 

He walked over to the laptop and typed in the final execution command.

 

[WARNING: INITIATING AUTOMATED SURGICAL PROTOCOL. PROCEED?]

 

Izuku stared at the flashing cursor. His mind screamed at him to stop. This was madness. This was self-mutilation. He was a fourteen-year-old kid about to perform amateur neurosurgery on himself in a garbage dump.

 

“I honestly don't think you can become a hero without a Quirk.”

 

All Might's voice echoed in his skull. The phantom sensation of the sludge villain filling his lungs made him gag.

 

Izuku slammed his finger onto the 'ENTER' key.

 

He quickly climbed onto the plastic-wrapped table, lying face down on the padded headrest. He reached awkwardly behind his neck with the syringe, injecting the local anesthetic into the skin above his spine. He bit down on a thick leather belt he had placed between his teeth.

 

The robotic arms whirred to life, descending from the ceiling.

 

"System active," a synthesized voice chimed from the laptop. "Commencing incision."

 

Izuku squeezed his eyes shut.

 

Despite the lidocaine, he felt the pressure as the scalpel dragged down the center of his upper back, slicing through the epidermis and dermis. He tasted blood as his jaw clamped down on the leather belt. Warmth spilled down his sides.

 

Whirrrrr.

 

The robotic clamps engaged, pulling the skin and muscle apart to expose the bone. The pain was nauseating. The local anesthetic only numbed the surface; it did nothing for the deep, visceral agony of his muscles being forcibly retracted.

 

"Deploying drill."

 

The high-pitched whine of the micro-drill filled the small room, drowning out the storm outside.

 

When the drill bit made contact with his vertebrae, Izuku's entire world shattered. The vibration traveled straight into his skull, a deafening, bone-rattling agony that defied description. Tears streamed horizontally across his face, pooling on the plastic table. His hands gripped the edges of the metal table so hard his fingernails bent backward.

 

Crunch. Whine. Crunch.

 

The machine was drilling anchor points into his bone. He was being bolted together like a machine.

 

"Inserting NSI."

 

Izuku felt the cold, hard metal of the processor being pressed into the carved hollow of his spine. But the worst was yet to come.

 

"Deploying synaptic filaments."

 

The platinum wires extended, piercing the protective sheath of his spinal cord. The moment the metal touched his raw nerves, a shockwave of pure electricity exploded through Izuku's nervous system. It felt like being struck by lightning from the inside out. His arms and legs spasmed violently, uncontrollable biological reactions to the invasive foreign object.

 

A cacophony of white noise flooded his brain. His vision flared with blinding static.

 

Through the roaring in his ears, he faintly heard the robotic rig disengaging and the cauterizing laser sealing the wound around the metal port that now sat flush with his skin.

 

Then, his consciousness mercifully gave way, plunging him into the dark.

 

 

 

Izuku woke up screaming.

 

He thrashed wildly, tangled in sweat-soaked bedsheets. The harsh morning sunlight was streaming through his bedroom window.

 

Wait. His bedroom window?

 

Izuku froze, his chest heaving. He was in his apartment. He was in his own bed.

 

Panic seized him. He tried to sit up, but a wave of blinding nausea and a sharp, ripping pain in his upper back slammed him back into the mattress. He was burning up. His skin felt like it was on fire, radiating heat. A fever.

 

"Izuku!"

 

The bedroom door flew open. Inko Midoriya rushed in, her face pale, her eyes red and swollen from crying. She held a damp washcloth and a glass of water.

 

"Mom?" Izuku croaked, his throat sandpaper dry.

 

"Don't move, sweetie! Please don't move!" Inko sobbed, rushing to his side and pressing the cool cloth to his forehead. "Your fever is at 104 degrees. I... I was about to call an ambulance."

 

"No!" Izuku gasped, his hand shooting out to grab her wrist with startling strength. "No hospitals. No doctors."

 

"Izuku, you're severely sick!" Inko cried, her voice trembling. "When you didn't come home last night, I went looking for you. I used the tracker app on your phone. It took me to... to that horrible beach."

 

Izuku's blood ran cold.

 

"I found that metal box," Inko continued, tears spilling over her cheeks. "I found you unconscious on a table, covered in blood! Izuku, what were you doing?! What is that... that thing in your back?!"

 

She had seen it. The jig was up. The secret was out.

 

Izuku let go of her wrist and let his head fall back onto the pillow. He felt defeated. He had survived the surgery, but his own mother was going to dismantle his dream. She would call the authorities. They would label him a danger to himself, rip the tech out of his spine, and lock him away in a psychiatric ward.

 

"I'm fixing myself, Mom," Izuku whispered, staring blankly at the ceiling.

 

"Fixing yourself? By mutilating your body?!" Inko’s voice rose an octave in pitch, a mixture of terror and maternal fury. "Izuku, there is a piece of metal bolted into your spine! The skin around it is inflamed and infected! You're suffering from acute rejection!"

 

"It's a Neural-Spine Interface," Izuku recited, his voice monotone, detached from the pain. "It intercepts motor-cortex signals. It's the only way I can eliminate latency in cybernetic prosthetics. It's the only way I can fight."

 

"Fight who?!" Inko screamed. "You're a fourteen-year-old boy! You are Quirkless! Why can't you just accept that and live a safe, normal life?!"

 

The word hung in the air like a poisoned blade. Quirkless.

 

Something snapped inside Izuku. The feverish haze burned away, replaced by a cold, furious clarity. He forced himself up, ignoring the agonizing pull of the stitches in his back. He swung his legs over the edge of the bed and stood up, swaying slightly.

 

Inko backed away, shocked by the sudden intensity in her son's eyes. They didn't look like the wide, innocent eyes of her little boy anymore. They looked older, harder, and glowing with an obsessive light.

 

"A normal life?" Izuku demanded, his voice dropping to a low, trembling register. "You mean a life where I keep my head down? Where I let Bakugo burn me every day? Where I let the world tell me I'm genetically inferior? A life where I apologize for existing?"

 

"Izuku, I never said—"

 

"You didn't have to!" Izuku shouted, the raw emotion finally tearing through his stoic facade. Tears of anger welled in his eyes. "When I was four years old, and the doctor told me I was Quirkless... what did you do, Mom? Did you tell me I could still be a hero? Did you tell me we would find a way?"

 

Inko froze. The memory of that day—the day she had sat on the floor and apologized to her crying son—hit her like a physical blow.

 

"No," Izuku said, his voice cracking. "You hugged me and said 'I'm sorry.' You gave up on me before I even started. And you know what? All Might said the same thing. The whole world says the same thing. Because I don't have magic blood, I'm worthless."

 

He reached behind his neck, his fingers grazing the hard, metallic edge of the NSI port protruding through his skin.

 

"I am not waiting for a miracle anymore," Izuku declared, his voice hard as steel. "I am building one. I am going to U.A. High School. I am going to tear down the system that says biology dictates destiny. And I am going to be a hero on my own terms. Even if I have to replace every inch of my flesh with iron to do it."

 

Silence descended on the bedroom.

 

Inko stared at her son. She saw the fever flush in his cheeks, the dark circles under his eyes, and the blood seeping through the bandages she had wrapped around his chest and back. But beneath the physical wreckage, she saw a will that was utterly unbreakable.

 

He was not going to stop. If she took away his tools, he would find others. If she locked him in, he would break out. He would keep pushing his frail, human body until the scrap metal he was welding into his flesh finally killed him.

 

The realization struck her with the force of a tidal wave. She couldn't stop him.

 

But she could save him.

 

Inko looked down at her hands, trembling violently. Then, she took a deep, shuddering breath and looked up at her son. The terror in her eyes was replaced by a fierce, terrifying maternal resolve.

 

"You used scrap metal," she said, her voice eerily calm.

 

Izuku blinked, taken aback. "W-What?"

 

"The processor in your back. The wire. It's unsterilized scrap metal from a junkyard, isn't it?"

 

"I... I sterilized it with iodine and—"

 

"That's not good enough!" Inko snapped, stepping forward. "You're suffering from metal toxicity and sepsis. Your body is rejecting the foreign material because it's cheap, dirty junk."

 

Izuku backed up a step, confused by the sudden shift. "Mom, I don't—"

 

"Sit down on that bed right now," Inko ordered, pointing a trembling finger at the mattress. "You are my son. If you are determined to... to turn yourself into a cyborg, you are not going to do it with rusty car parts."

 

Izuku stared at her, stunned. "Mom?"

 

Inko walked over to his desk, grabbed his black notebook, and shoved it into his chest.

 

"Write," she commanded, tears streaming down her face even as her voice remained firm. "Write down every single medical-grade material you need. Surgical titanium. Biocompatible silicone. Immunosuppressants. Proper antibiotics. Everything. I don't care how much it costs. I will empty my savings account. I will take out a second mortgage on this apartment. But if you are going to do this, Izuku, you are going to do it right. So you don't die on me."

 

Izuku looked at the notebook, and then up at his mother. The barrier between them shattered.

 

He collapsed onto his knees, wrapping his arms around his mother's waist, burying his face in her apron. He sobbed, the emotional weight of the past four months finally breaking him. Inko dropped to her knees, holding him tightly, crying into his hair.

 

She was terrified. She hated what he was doing. But she loved him more than she hated the metal.

 

 

 

The remaining six months leading up to the U.A. Entrance Exam were a period of rapid, terrifying evolution.

 

With Inko's financial backing, Project OVERDRIVE ascended from junkyard tinkering to high-level bioengineering. The shipping container was upgraded. Inko bought him a professional-grade sterilization unit, a proper welding station, and high-end computer processors. She used her connections as a legal assistant to quietly acquire restricted medical supplies—chiefly, broad-spectrum immunosuppressants to stop his body from rejecting the implants, and high-grade surgical titanium.

 

The first step was fixing the NSI.

 

With proper local anesthetics and his mother nervously monitoring his vitals on a purchased EKG machine, Izuku re-opened his back. He removed the salvaged drone processor and replaced it with a custom-built, bio-compatible microchip housed in a medical-titanium casing. The platinum wires were replaced with synthetic neural-lace, a material designed to mimic human nerve tissue, integrating seamlessly with his spinal cord.

 

Once the NSI was properly installed and the fever broke, the true grueling work began: Physical Therapy.

 

Having a computer chip wired into your central nervous system was not a seamless experience. The human brain was not designed to process digital telemetry.

 

For the first month after the surgery, Izuku suffered from what he called "Reverse Phantom Limb Syndrome." He could feel limbs that weren't there. The NSI was constantly projecting digital signals into his motor cortex, waiting for external hardware to connect. He suffered from blinding migraines, nosebleeds, and occasional muscle spasms as his brain tried to map biological commands to non-existent digital pathways.

 

He had to train his brain to accept a secondary, artificial nervous system.

 

He sat cross-legged on the floor of the shipping container for hours a day, his eyes closed, holding a simple robotic arm wired to the port on his back.

 

Move a finger, he thought.

 

His biological hand would twitch. The robotic hand would remain still.

 

No. Don't move the flesh. Move the iron.

 

It required a complete rewiring of his subconscious. He had to learn to compartmentalize his motor functions. It was like learning to breathe underwater while simultaneously juggling. The mental strain was immense. He often passed out from sheer cognitive overload, waking up to the smell of copper in his nose from the bleeding.

 

But Izuku Midoriya had spent ten years analyzing, studying, and adapting. His brain was a sponge, uniquely conditioned to process complex information.

 

By month seven, he achieved synchronization.

 

He sat at his desk, his arms crossed over his chest. Sitting on the workbench, unconnected to any physical controls, a mechanical arm fluidly picked up a pen, twirled it between its metallic fingers, and wrote ‘I AM HERE’ on a piece of paper.

 

Izuku smiled, wiping a trickle of blood from his nostril.

 

With the software integrated, he moved to the final phase: the hardware.

 

If he was going to fight alongside people with Quirks, he needed more than just a spinal port. He needed anchor points.

 

Over the next two months, he performed three more surgeries on himself.

 

He installed sub-dermal titanium mounting ports into his forearms, locking them directly onto his radius and ulna bones. He installed similar ports into his calves, anchoring them to his tibia. These weren't full amputations—he wasn't ready to throw away his biological limbs just yet. These were hardpoints. Sockets that allowed him to bolt heavy cybernetic enhancements directly onto his skeleton, drawing power from external battery packs and commands directly from his spine.

 

By month nine, his body had changed.

 

He had grown taller, but his physique was strange. He was lean, almost dangerously so, his metabolism constantly burning calories to heal the surgical trauma and fuel the implants. His skin was pale from spending all his time in the container. Down the center of his spine, a sleek, flat strip of dark metal was visible through his skin, featuring a universal data-jack at the base of his neck. Down his forearms and calves, smooth, circular metallic ports sat flush with his skin, waiting to be connected.

 

He was a cyborg.

 

With his body prepared, Izuku spent the final month constructing his weapons.

 

He discarded the bulky exoskeleton design. He needed something sleek, fast, and devastating. He designed the "O.D. Gauntlets" (Overdrive Gauntlets).

 

They were not gloves. They were heavy, segmented sleeves of matte-black carbon-fiber and titanium. They were designed to slide over his biological arms and physically bolt into the sub-dermal ports on his forearms. Once bolted in, data cables would snake up his back and plug into his spinal NSI port.

 

The gauntlets housed synthetic carbon-nanotube musculature, acting as a secondary layer of hyper-dense muscle over his own. Hidden beneath the armor plating on the knuckles were high-pressure pneumatic impact-actuators. Upon impact, a micro-sensor would trigger a blast of compressed air, driving the fist forward an extra three inches with the force of a detonating artillery shell.

 

He designed a similar pair of enhancements for his legs: the "O.D. Greaves." They featured internal gyroscopes for balance and pneumatic pistons in the heels designed to absorb the kinetic shock of long-distance jumps and deliver devastating kicking power.

 

Everything was painted matte black, accented by the glowing green LED lights of the cooling systems and data-transfers.

 

 

 

It was the dawn of the U.A. Entrance Exam.

 

The morning air was crisp and cool. Takoba Municipal Beach was unrecognizable. Over the past ten months, in order to test his equipment, salvage parts, and hide his activities, Izuku had accidentally cleaned up half the beach. Massive craters were blasted into the sand, and mountains of scrap metal had been neatly sorted, dismantled, or pulverized into dust.

 

Izuku stood on the shoreline, watching the sun rise over the ocean. The waves lapped gently against the clean sand.

 

He wore a simple black undershirt and baggy cargo pants. Lying on the sand at his feet were two heavy metal cases.

 

He knelt, unlatching the first case. Inside rested the O.D. Gauntlets, sleek, dangerous, and pristine.

 

He picked up the right gauntlet. It was heavy, weighing almost twenty pounds. He slid his biological arm into the hollow cylinder. The interior was lined with bio-compatible foam that conformed to his skin.

 

He aligned the locking pins with the titanium ports embedded in his forearm.

 

Clack. Clack. Hiss.

 

The gauntlet locked into his skeleton. The pneumatic seals pressurized, tightening around his arm. Izuku hissed through his teeth as the metal clamped down, a brief flash of pain giving way to a feeling of immense, anchoring weight. He repeated the process with his left arm.

 

Next, he reached behind his neck. He pulled the twin braided data cables attached to the shoulders of the gauntlets and plugged them into the NSI jack at the base of his skull.

 

The integration was instantaneous.

 

Izuku gasped, his back arching as a surge of data flooded his motor cortex. His vision flickered, an augmented reality HUD—projected via smart-contacts he had developed—flaring to life in his eyes.

 

[SYSTEM BOOT. OVERDRIVE OS V1.0]

[NEURAL LINK: 100%]

[MOTOR CORTEX SYNC: OPTIMAL]

[PNEUMATIC PRESSURE: MAXIMUM]

 

The heavy, twenty-pound gauntlets suddenly felt as light as feathers. They were no longer metal tubes wrapped around his arms. His brain registered them as his actual arms. He could "feel" the air currents brushing against the carbon fiber. He could "feel" the potential energy coiled in the pneumatic pistons, waiting to be unleashed.

 

He flexed his fingers. The massive, sharp-edged metallic digits of the gauntlets mirrored the movement instantly, with zero latency. The synthetic muscle fibers whirred softly, a sound like a predatory cat purring.

 

He was ready.

 

Izuku turned his attention to a massive, junked double-door industrial refrigerator standing fifty yards away. It was a solid block of thick steel and insulation, weighing nearly eight hundred pounds.

 

He lowered his stance, bending his knees. He didn't have his greaves on yet, relying purely on his biological legs for this test.

 

He focused his mind on the right gauntlet. He didn't think about firing pistons or activating actuators. He just thought: Hit it hard.

 

The digital command traveled down his spine, bypassing his biological muscles entirely, flashing through the data cables and into the gauntlet's processor in a fraction of a millisecond.

 

Izuku moved.

 

He kicked off the sand, crossing the fifty yards in a blur of motion. He planted his left foot, twisting his hips, and drove his right metallic fist forward.

 

The strike was a symphony of engineering.

 

The carbon-nanotube muscles contracted, multiplying the torque of his swing by a factor of fifty. As the knuckles made contact with the steel door of the refrigerator, the impact-sensors triggered.

 

THOOM.

 

The pneumatic piston in the forearm fired. A blast of compressed air exploded from the exhaust vents on the back of the gauntlet, driving the fist three inches deeper into the target with the concussive force of a bomb.

 

The sound was deafening, a sickening crunch of tearing metal that echoed across the bay.

 

The eight-hundred-pound refrigerator didn't just dent. It ruptured. The steel doors were blown completely off their hinges, rocketing backward and embedding themselves into the sand twenty feet away. The structural frame of the fridge crumpled inwards, folding entirely in half around Izuku's fist before the sheer kinetic transfer launched the entire mass into the air, flipping it end over end until it crashed into a distant pile of tires.

 

A cloud of sand and dust plumed into the air.

 

Izuku stood frozen in his follow-through stance. Steam hissed from the cooling vents on his gauntlet. The metal knuckles were glowing a faint, dull red from the friction of the impact, but they were completely unblemished.

 

He slowly lowered his arm. He didn't feel a single ounce of pain in his biological hand or forearm. The gauntlet had absorbed one hundred percent of the kinetic recoil, grounding it through the titanium ports and into his skeletal structure.

 

He looked at the devastated machinery in the distance. He had just hit with the force of a mid-tier strength Quirk. And he hadn't even pushed the system to its maximum output.

 

Izuku looked down at his metallic hands. He opened and closed them, listening to the soft, rhythmic whir of the servos.

 

For ten years, he had been a victim. He had been weak, frail, and powerless, at the mercy of a society that worshipped the genetic lottery. He had cried, he had begged, and he had bled.

 

But as he stood on the beach, the morning sun reflecting off his carbon-fiber armor, the tears were gone. The fear was gone. The boy who cowered before Bakugo’s explosions was dead, left behind on a rooftop with All Might.

 

In his place stood something new. Something forged in the fires of obsession and tempered by the cold, unforgiving logic of science.

 

Izuku Midoriya unlatched the gauntlets, packed them carefully back into their cases, and slung the heavy bags over his shoulders. He turned his back on the junkyard and began the long walk toward U.A. High School.

 

The exam was today.

 

And the heroes were not ready for him.

 

 

 

 

The gates of U.A. High School were legendary, towering arches of glass and steel that represented the pinnacle of heroic society. For generations, they had served as the threshold between the ordinary and the extraordinary. Millions of aspiring students had walked beneath them, their veins humming with the genetic blessings of Quirks, their heads filled with dreams of fame, glory, and justice.

 

Izuku Midoriya walked beneath them feeling nothing but the oppressive, comforting weight of his own engineering.

 

It was a chilly morning in late February, yet Izuku was sweating. He was wearing an oversized, heavy canvas olive-drab trench coat that fell past his knees. The collar was popped high, obscuring his neck, and the thick material completely swallowed his frame. To the outside observer, he looked like a nervous, eccentric teenager trying too hard to look mysterious, or perhaps someone trying to hide a rather cumbersome heteromorphic mutation.

 

The truth was far heavier.

 

Underneath the canvas, Izuku was carrying roughly sixty pounds of high-grade cybernetic hardware.

 

The O.D. Gauntlets were bolted securely into the titanium sub-dermal ports in his forearms, the carbon-fiber plating cold against his skin. The O.D. Greaves were locked into his calves, the pneumatic heel-actuators hissing softly with every step he took, absorbing the immense weight so his biological muscles wouldn't tear before the exam even began. Braided data cables snaked from the limbs, running up his back beneath his shirt, plunging directly into the Neural-Spine Interface at the base of his skull.

 

He was essentially wearing a weaponized exoskeleton, except the skeleton was his own.

 

“Breathe,” Izuku thought, closing his eyes for a fraction of a second. “Regulate heart rate. Conserve battery.”

 

As he blinked, a faint green light flickered in his pupils. Over the past month, Izuku had recognized a glaring flaw in his design: sensory input. He had zero latency between his brain and his limbs, but his biological eyes were still human. They could only track movement so fast. They couldn't see infrared. They couldn't instantly calculate distance, velocity, or structural weaknesses.

 

So, he had built the Optic-Sync Tactical Visor.

 

Right now, it rested on his forehead, concealed by his messy mop of green hair—a sleek, angular piece of polarized smart-glass. But it was already active, communicating wirelessly with the NSI. Even without the visor pulled down, a minimalist Heads-Up Display (HUD) was projected directly onto his retinas via custom-built, bio-compatible smart contacts.

 

As he walked up the main path toward the auditorium, data scrolled across the periphery of his vision.

 

[SYS.CHK: NOMINAL]

[BATTERY (CORE): 98%]

[PNEUMATIC PRESSURE: 4000 PSI]

[THERMAL REGULATORS: STABLE]

 

He was a ghost in the machine of society. A Quirkless anomaly walking into the belly of the beast.

 

"Out of the way, Deku!"

 

The voice was like a match struck in a powder keg. Rough, abrasive, and dripping with absolute contempt.

 

Izuku stopped walking. He didn't flinch. He didn't cower, pull his arms up, or squeak in terror—the automatic biological responses that Katsuki Bakugo had beaten into him over a decade of torment. Instead, Izuku just turned his head.

 

Bakugo was storming up the walkway, his hands shoved deep into his pockets, his crimson eyes locked onto Izuku with a mixture of disgust and genuine confusion. Bakugo had expected the usual reaction. The trembling. The stuttering. But Izuku just stood there, his posture perfectly straight, his eyes cold and unreadable.

 

The HUD in Izuku’s vision instantly locked onto his childhood tormentor.

 

[TARGET ACQUIRED: KATSUKI BAKUGO]

[HEART RATE: 85 BPM (ELEVATED)]

[MUSCLE TENSION: HIGH IN UPPER EXTREMITIES]

[THREAT LEVEL: CLASS-A BIO-KINETIC]

 

"I said move, you Quirkless piece of garbage," Bakugo growled, stepping into Izuku's personal space. Sparks popped violently in his palms, the smell of burnt sugar and nitroglycerin wafting into the air. "What the hell are you even doing here? You trying to get yourself killed? They don't let rejects take the exam."

 

For ten years, Izuku would have broken eye contact. He would have apologized for breathing the same air.

 

Today, the O.D. Gauntlet on his right arm whirred almost imperceptibly beneath the trench coat. The synthetic muscle fibers tensed, anticipating a kinetic strike command. Izuku looked at Bakugo, really looked at him, and realized something profound.

 

Bakugo was just biology. He was a fleshy bag of water, bone, and unstable chemicals. A stray piece of shrapnel to the knee, a severed nerve, a punctured lung, and his Quirk was useless. He was fragile.

 

"I'm taking the exam, Bakugo," Izuku said. His voice was calm, steady, and devoid of the familiar stutter. It sounded alien even to his own ears.

 

Bakugo scowled, leaning in closer, the sparks in his hands growing larger. "You're taking the exam? With what? Are you going to cry on the robots until they short circuit? Or are you hiding some new toys under that stupid coat? Support gear won't save you from being a Deku."

 

"We'll see," Izuku replied simply.

 

He didn't wait for Bakugo to respond. He simply turned and continued walking.

 

Bakugo stood frozen on the pavement, his explosive hands falling to his sides. His jaw twitched. A strange, unsettling shiver ran down his spine. It wasn't fear, exactly—Bakugo didn't know the meaning of the word—but it was the profound discomfort of encountering something fundamentally wrong. Deku hadn't trembled. Deku hadn't smiled weakly. Deku's eyes had looked like dead, green glass.

 

"Whatever, you damn nerd," Bakugo spat at the ground, storming past him. "I hope a robot crushes you."

 

Izuku barely registered the threat. He was already recalibrating his auditory sensors, tuning out the ambient noise of the crowd.

 

As he approached the massive doors of the auditorium, a sudden blur of motion caught his eye. A girl with round cheeks and short brown hair tripped over an uneven paving stone. Gravity took hold, and she pitched forward, heading face-first for the concrete.

 

Before Izuku even made the conscious decision to act, his NSI processed his intent.

 

Catch her.

 

Underneath the coat, the O.D. Greaves fired. A burst of compressed air shot from his left heel, launching his body forward with unnatural, mechanical speed. To the surrounding students, Izuku seemed to simply teleport across the five feet of space.

 

He caught the girl by the shoulders just an inch before her face hit the ground. The sudden stop exerted immense force, but the titanium locks in Izuku's forearms held the weight effortlessly, the servo-motors humming under the heavy canvas.

 

"Whoa!" the girl gasped, her eyes wide. She looked down, realizing she was hovering above the ground, and then looked up at Izuku. "H-Hey! Thanks!"

 

She touched her fingertips together. Suddenly, the weight of her body vanished entirely from Izuku's grip. She righted herself, floating upright before gently touching the ground again.

 

"That's my Quirk," she said, rubbing the back of her head with a bright, embarrassed smile. "Zero Gravity. I'm Ochaco Uraraka. Man, I was so nervous I tripped over my own feet! Good thing you have such fast reflexes! What's your Quirk? Super speed?"

 

Izuku’s HUD was already analyzing the localized gravitational distortion around her. [GRAVIMETRIC ANOMALY DETECTED. BIOLOGICAL TOUCH-BASED ACTIVATION.]

 

"Something like that," Izuku lied smoothly, releasing his grip and shoving his hands deep into his coat pockets. "Be careful on the stairs."

 

He didn't linger to chat, brushing past her and walking into the darkness of the auditorium. Uraraka stood there for a moment, blinking in surprise at the terse interaction.

 

"Intense guy..." she muttered.

 

 

 

The auditorium was a massive, stadium-style theater packed with thousands of nervous teenagers. Izuku found a seat near the middle, perfectly situated to calculate the acoustics of the room. Ironically, he ended up seated right next to Bakugo, who merely grunted and glared at the stage.

 

The lights dimmed. A single spotlight snapped onto the podium, revealing the towering, leather-clad form of the Voice Hero: Present Mic.

 

"WHAT'S UP, U.A. CANDIDATES?!" Mic roared, leaning back and throwing his arms wide. The sheer decibel level of his voice physically rattled the seats.

 

Instantly, Izuku's optical HUD flashed red.

[WARNING: HIGH DECIBEL EXPOSURE. ENGAGING AUDIO DAMPENERS.]

 

The smart-contacts interfaced with a tiny subdermal receiver near Izuku's eardrums, emitting an inverse soundwave that perfectly canceled out the harmful frequencies of Present Mic's Quirk. The booming roar became a manageable, normal speaking volume in Izuku's ears.

 

"Let me hear ya say HEEEYYYY!" Mic screamed.

 

Silence. The crowd was paralyzed with nerves.

 

"Tough crowd! That's fine! Let me break down the practical exam for you!" Mic pointed to a massive screen behind him, which lit up with a video-game-style graphic.

 

Izuku didn't cheer. He didn't geek out over his favorite radio host like he would have a year ago. He simply watched the data.

 

"You'll be conducting ten-minute mock urban battles!" Mic explained. "You've all been randomly assigned to different battle centers to prevent teaming up with friends. Inside, you'll find three types of faux villains, worth one, two, or three points! Use your Quirks to disable them and rack up the score!"

 

‘Robotics,’ Izuku mused, a cold smile tugging at the corner of his mouth beneath his collar. ‘They want me to fight machines. They built an exam out of the very things I spent ten months ripping apart with my bare hands.’

 

"Excuse me, sir! I have a question!"

 

A tall, broad-shouldered boy with glasses and neatly combed blue hair stood up abruptly, pointing a rigid arm in the air. A spotlight found him instantly.

 

"On the printout, there are four types of villains! If this is a misprint, U.A., the most prominent academy in Japan, should be ashamed of that foolish mistake!"

 

The boy then turned, his rigid arm swinging like a metronome to point directly at Izuku.

 

"And you! With the heavy coat! You've been muttering and shifting around this entire time. If you are here on a pleasure trip, or if you can't handle the heat of the room, you should leave immediately! You are distracting the rest of us who are taking this seriously!"

 

A year ago, Izuku would have curled into a ball of sheer, unadulterated panic, apologizing profusely to the entire room.

 

Today, Izuku slowly turned his head to look at the boy. The blue-haired teenager—Tenya Iida, Izuku recognized him from his old notebook on biological engines—was glaring at him with righteous indignation.

 

Izuku didn't raise his voice. He didn't apologize. He reached up, tapped his temple, and spoke in a clear, carrying tone.

 

"I am running a localized diagnostic on my support equipment to ensure it functions within U.A. regulatory guidelines," Izuku stated, his voice ringing out clearly in the silent auditorium. "If the ambient hum of a cooling fan is enough to break your concentration, I suggest you reevaluate your readiness for a live combat zone, where the noise of collapsing buildings and screaming civilians will be significantly louder."

 

The auditorium went dead silent.

 

Iida blinked, his rigid posture faltering for a second. His mouth opened, closed, and then he bowed stiffly at a perfect ninety-degree angle. "I... I apologize! Your reasoning is entirely sound! Please forgive my presumption!"

 

"Whatever," Izuku muttered, turning back to the stage.

 

Bakugo, sitting next to him, was staring at Izuku as if the green-haired boy had sprouted a second head. Since when the hell does Deku talk back?

 

Present Mic cleared his throat, breaking the tension. "Okay, okay, examinee number 7111! Thanks for the segue! The fourth villain type is worth zero points! It's a massive obstacle! I recommend you run away from it!"

 

‘A hazard,’ Izuku noted, his mind already formulating a tactical overlay. ‘Area denial unit. Avoidance is optimal for energy conservation.’

 

"That's all from me! I leave you with our school motto! Go beyond... PLUS ULTRA!"

 

 

 

Battle Center B was a breathtaking feat of engineering. It was a fully functional, miniature metropolis enclosed by walls that scraped the sky. Skyscrapers of glass, asphalt roads, and concrete alleys formed a complex urban combat environment.

 

Izuku stood near the front of the massive crowd of teenagers waiting before the gargantuan metal gates. He was still wearing the trench coat. He could feel the stares burning into his back. Whispers drifted through the crowd.

 

“Is that the guy who talked down the engine kid?”

“Why is he wearing a winter coat?”

“He looks weak. Probably a sensory Quirk. Easy competition.”

 

Izuku ignored them. He was running his final pre-flight checks.

 

[NSI LINK: STABLE]

[ADRENALINE LEVELS: ELEVATED (COMBAT OPTIMAL)]

[ENGAGING TACTICAL VISOR]

 

Izuku reached up and pulled the angular, polarized visor down over his eyes. It clicked into place with a soft, magnetic hum. The world shifted. The normal, bright daylight was overlaid with a crisp, geometric interface. Targeting reticles danced across his vision, measuring the distance to the gates, the height of the walls, and the ambient temperature of the air.

 

High above, in a darkened monitoring room, dozens of monitors displayed live feeds of the Battle Centers. The faculty of U.A. High watched intently.

 

"They look like a promising batch this year," a small, white mouse-bear-dog creature in a suit—Principal Nezu—remarked cheerfully, sipping a cup of tea.

 

Sitting in the darkest corner of the room, wrapped in a yellow sleeping bag, Shota Aizawa stared at the screen showing Battle Center B. His eyes narrowed, focusing on the green-haired boy in the coat.

 

"Who is the kid in the winter gear?" Aizawa asked, his voice a raspy drawl. "Is he trying to induce a heat stroke?"

 

Next to him, a pro hero wearing a construction helmet and heavily modified excavator claws on his arms—Power Loader, the head of the Support Course—leaned closer to his own monitor.

 

"Midoriya, Izuku," Power Loader read from a digital file. "Quirkless. But he submitted a massive support item authorization form. The paperwork is insane. It says he’s using... cybernetic enhancements? Integrated directly into his nervous system? That can't be right. He's fourteen."

 

Standing in the back of the room, in his skeletal, un-buffed form, Toshinori Yagi—All Might—suddenly gripped the railing. Young Midoriya? he thought, his heart skipping a beat. What is he doing here? I told him it was impossible. He'll be crushed!

 

Suddenly, Present Mic’s voice boomed over the PA system at the Battle Center.

 

"RIGHT, LET'S START! WHAT'S WRONG? THERE ARE NO COUNTDOWNS IN REAL BATTLES! RUN, RUN, RUN!"

 

The massive gates began to grind open.

 

The crowd of hundreds of students froze for a split second, processing the abrupt start.

 

Izuku didn't hesitate.

 

‘Initiate Overdrive.’

 

He grabbed the lapels of his heavy trench coat and ripped it open. He shrugged the massive garment off, letting it fall to the asphalt, finally revealing the culmination of ten months of blood, sweat, and scrap metal.

 

The collective gasp from the students around him was audible.

 

Izuku’s arms were encased in the massive, matte-black O.D. Gauntlets, thick carbon-fiber plates shielding the complex array of synthetic muscles, copper wiring, and pneumatic pistons. At his calves, the O.D. Greaves flared, heavy titanium boots spiked into the asphalt. Down the center of his spine, visible through a modified cut in the back of his tight black shirt, the Neural-Spine Interface pulsed with a steady, menacing green light, data cables weaving into his armor.

 

He didn't look like a hero student. He looked like a weapon of war.

 

Hiss. CLACK.

 

The pneumatic heels on his greaves compressed.

 

Izuku shot forward like a bullet fired from a railgun. The asphalt beneath his boots cracked from the sheer kinetic launch. Before the rest of the students had even taken their first step, Izuku was fifty yards deep into the city, moving with a terrifying, mechanical grace.

 

"Holy crap! He's a cyborg!" someone in the crowd yelled, finally breaking the paralysis. The stampede began.

 

Izuku was already airborne.

 

He rounded the first corner and came face-to-face with a group of three 1-Pointer robots. They were sleek, unicycle-based machines equipped with tracking sensors and light offensive cannons.

 

"Target acquired," the robotic voices droned in unison.

 

Izuku didn't slow down. His visor painted the three robots in bright red.

 

[ANALYZING TARGETS... WEAKNESS DETECTED: GYROSCOPIC STABILIZER LOCATED BENEATH MAIN OPTIC]

 

Izuku didn't use brute force. He didn't need to punch through their armor. He just needed to break them.

 

He lunged at the first robot. He didn't throw a traditional punch; instead, his right gauntlet snapped forward in a blindingly fast, open-palm strike. The pneumatic piston inside the arm fired with a loud THOOM, driving the heel of his metal hand directly into the space below the robot's optic sensor.

 

The impact shattered the gyroscopic housing. The 1-Pointer instantly lost its balance, screeching as it tipped backward and violently crashed into the pavement, its internal systems short-circuiting.

 

One point.

 

Izuku used the momentum of his strike to spin on his heel. The second robot fired a rubber bullet at him. Izuku didn't dodge. He simply raised his left forearm. The bullet plinked harmlessly off the carbon-fiber armor.

 

He closed the distance in two steps, grabbed the barrel of the robot's gun with his left gauntlet, and squeezed. The servo-motors whined, generating hundreds of pounds of pressure. The steel barrel crumpled like tin foil.

 

Two points.

 

For the third robot, Izuku decided to test his area-of-effect weaponry. He leaped backward, putting ten feet of distance between them. He aimed his right palm at the machine.

 

"Discharge," Izuku commanded through his NSI.

 

A high-density capacitor housed in his forearm released its stored energy. An Electromagnetic Pulse (EMP) emitter built into the palm of the gauntlet flashed with blinding blue light.

 

CRACK-BZZZT.

 

The localized EMP wave washed over the 3-Pointer. Every circuit board, sensor, and motor inside the machine instantly fried. The robot seized up, smoke pouring from its chassis, and collapsed into a heap of scrap.

 

Three points in under ten seconds.

 

Izuku exhaled, a plume of steam venting from the cooling vents on his shoulders. He didn't smile. He didn't celebrate. He just looked at the HUD.

 

[SEEKING NEW TARGETS. 9 MINUTES 45 SECONDS REMAINING.]

 

He took off running again, a blur of black metal and green light.

 

 

 

In the monitoring room, the silence was deafening.

 

The faculty of U.A. watched the feed of Battle Center B in absolute awe. They were used to seeing kids with explosive strength, elemental powers, or enhanced speeds. They were not used to seeing surgical, mechanized butchery.

 

"Good lord," Midnight whispered, her hand over her mouth. "His movements... there's no wasted energy. It's like watching a machine."

 

"It's because he is partially a machine right now," Power Loader said, his eyes glued to the screen, feverishly typing on his own console to analyze Izuku's telemetry. "Look at the reaction times! He's dodging projectiles before the robots even finish pulling their triggers. The latency between his decision-making and physical movement is zero. That spinal tap... it's overriding his biological nervous system. He's commanding that armor at the exact speed of thought."

 

"But the strain!" Recovery Girl gasped, hitting the table with her cane. "The human body isn't meant to channel that much raw kinetic force! Even if the metal absorbs the impact, the sheer G-force of his movements should be tearing his biological ligaments to shreds!"

 

"He's compensating," Aizawa noted, his tired eyes wide open, tracking Izuku's blur on the screen. "Look at his footwork. He's using the pneumatic bursts in his legs to counterbalance the recoil of his punches. He's mathematically calculating the kinetic transfer of every strike to minimize biological blowback."

 

Aizawa leaned back, a rare, terrifying grin spreading across his face.

 

"A Quirkless kid," Aizawa muttered. "Using pure intellect and scrap metal to outpace genetically gifted prodigies. Logical. Highly logical."

 

All Might stood frozen in the back. His heart was a chaotic mess of pride, terror, and profound guilt. My boy... you didn't give up. You built your own power.

 

On the screen, Izuku was a terror. He was treating the U.A. Entrance Exam like a junkyard scavenging run, dismantling 2-Pointers and 3-Pointers with ruthless efficiency. He ripped the treads off tank-bots. He used his grappling wires—spooled in the underside of his wrists—to swing around lampposts, launching himself onto the backs of larger robots to crush their central processors.

 

By the six-minute mark, Izuku had accumulated fifty-five points.

 

He was breathing heavily now. The inside of his tight black shirt was soaked with sweat. The NSI port on his spine was burning with a dull, throbbing heat. The human brain consumes a massive amount of calories just to function normally; processing high-speed combat telemetry on a secondary digital nervous system was pushing Izuku into dangerous metabolic territory.

 

[WARNING: CORE TEMPERATURE RISING. HYDRATION LEVELS CRITICAL.]

 

"Ignore," Izuku hissed, leaning against a concrete wall in an alleyway, taking a three-second breather. He watched as a boy with a laser-firing navel blew up a 2-Pointer down the street.

 

‘Fifty-five points should be enough to pass the written and practical combined,’ Izuku calculated, his analytical mind constantly churning. ‘I need to power down the primary combat protocols and focus on evasion until the timer runs out. Biological failure is imminent if I keep up this output.’

 

"LESS THAN TWO MINUTES REMAINING!" Present Mic's voice echoed across the fake city.

 

Suddenly, the ground beneath Izuku's metal boots began to tremble.

 

It wasn't a localized tremor. It was a rhythmic, earth-shattering quake that rattled the glass in the skyscrapers and sent cracks shooting across the asphalt. The shadows in the alleyway deepened as something massive blotted out the sun.

 

Izuku stepped out of the alley. His emerald eyes, framed by the digital glow of his visor, widened.

 

At the far end of the main street, towering over the four-story buildings, was a machine of apocalyptic proportions. The Zero Pointer. It was a colossal, heavily armored behemoth, its singular red optical sensor glaring down at the tiny humans below like an angry god.

 

With a deafening roar of grinding gears, the behemoth brought a fist the size of a house down upon the street. Buildings shattered. A shockwave of dust, concrete shrapnel, and concussive force swept through the avenue.

 

The examinees, previously emboldened by their scores, instantly shattered into a panicking mob.

 

"Run! It's the Zero Pointer!"

"Are they insane?! That thing could kill us!"

 

The crowd surged backward, fleeing the behemoth.

 

Izuku’s HUD immediately went into overdrive, calculating threat levels and structural integrity.

 

[THREAT LEVEL: OMEGA]

[ARMOR DENSITY: IMPENETRABLE BY CURRENT ARSENAL]

[RECOMMENDATION: IMMEDIATE EVACUATION]

 

"Agreed," Izuku muttered, turning on his heel to join the retreating crowd. There were no points to be gained here. The logical, calculated move was survival. He had proven his point. The machine was superior.

 

He took two steps before a sound pierced through the roaring chaos of the crumbling city.

 

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

 

Izuku froze.

 

His audio dampeners isolated the frequency. He snapped his head around, his optical zoom magnifying a spot near the base of the Zero Pointer's tread path.

 

It was the girl from the entrance. Uraraka. She was pinned beneath a massive slab of concrete that had fallen from a crushed building, her leg trapped. She was desperately trying to use her Quirk on the rubble, but she was exhausted, clutching her stomach and gagging.

 

And the Zero Pointer’s colossal tread was rolling directly toward her.

 

In the monitoring room, All Might gripped the railing, his knuckles turning white, preparing to burst out of the room and intervene.

 

In the Battle Center, Izuku Midoriya stood paralyzed.

 

For ten months, he had told himself that he was abandoning the naive dreams of his childhood. He had told himself that to compete in this world, he had to be cold, calculating, and purely logical. A machine. Machines didn't have feelings. Machines didn't risk their own structural integrity for an unquantifiable variable like a stranger's life.

 

But as Izuku looked at Uraraka, he didn't see a variable. He saw someone who needed to be saved.

 

Beneath the titanium ports, beneath the NSI, beneath the cold, hard logic of his brain, a deeply buried, biological instinct flared to life. The heart of a hero.

 

Izuku’s hands clenched into fists.

 

"System," Izuku whispered, his voice trembling with a mixture of terror and absolute resolve. "Disable all thermal and kinetic safety limiters. Route auxiliary battery power to the pneumatic actuators in the legs and right arm."

 

[WARNING!] the HUD flashed in blinding, frantic red text.

[SAFETY LIMITERS PREVENT CATASTROPHIC BIOLOGICAL DAMAGE. DISABLING LIMITERS WILL RESULT IN SEVERE KINETIC FEEDBACK, BONE FRACTURES, AND HARDWARE MELTDOWN.]

 

"I don't care," Izuku snarled, his eyes burning with a ferocious, feral light. "Do it."

 

[COMMAND ACCEPTED. INITIATING OVERCLOCK MODE.]

 

A high-pitched, agonizing whine erupted from the cyberware bolted to Izuku's body. The green LED lights on his NSI, his gauntlets, and his greaves suddenly shifted to a blinding, angry crimson. Steam began to violently vent from the seams of his armor.

 

He was pushing the hardware past its breaking point.

 

Izuku sprinted.

 

He didn't run like a human. He ran like a predator closing in on the kill. The Overclocked pneumatic greaves fired with every step, tearing massive craters into the asphalt. He was moving so fast the world around him blurred into streaks of gray and brown.

 

The Zero Pointer’s tread was ten feet away from Uraraka.

 

Izuku reached her, but he didn't stop to lift the rubble. He couldn't. If he stopped, the robot would crush them both. He had to stop the machine.

 

He planted his metal boots directly onto a shattered, slanted piece of concrete serving as a makeshift ramp.

 

"Maximum output!" Izuku screamed, his vocal cords tearing from the effort.

 

BOOM!

 

The explosive force of the leg actuators firing at three hundred percent capacity shattered the concrete ramp into dust. Izuku was launched into the air like a surface-to-air missile. The G-force pressed him into his own skeleton, his vision narrowing to a tunnel.

 

Up. Up. Higher than the four-story buildings. He soared through the air, aligning himself perfectly with the massive, armored faceplate of the Zero Pointer.

 

The colossal robot’s red optical sensor slowly tilted upward, registering the tiny, incoming threat.

 

In the monitoring room, the pros were on their feet.

 

"He's going to kill himself!" Recovery Girl shrieked.

"Look at his thermal readings!" Power Loader yelled, pointing at the monitor. "His right gauntlet is reaching melting point! The synthetic muscle is going to snap!"

 

Mid-air, falling toward the face of the mechanical god, Izuku pulled his right arm back.

 

He could feel the heat searing his biological skin beneath the carbon fiber. The synthetic muscles inside the gauntlet were winding up, tightening like a coiled spring of pure, unadulterated kinetic potential. The pneumatic cylinder in his forearm was pressurized so high the metal casing was bulging.

 

‘This isn't a Quirk,’ Izuku thought, gritting his teeth in excruciating pain. ‘This isn't magic. This is physics!’

 

"SMASH!"

 

Izuku thrust his fist forward.

 

The gauntlet connected with the solid steel center of the Zero Pointer’s faceplate.

 

For a microsecond, the world seemed to freeze. Then, the Overclocked pneumatic piston fired.

 

The resulting shockwave defied the laws of aerodynamics. A massive ring of compressed air exploded outward, visibly distorting the atmosphere and blowing the clouds away from the battlefield. The sheer, terrifying kinetic transfer ripped through the Zero Pointer's armor like a cannonball through wet paper.

 

The steel faceplate crumpled inward. The internal circuitry detonated. The shockwave traveled down the behemoth's spine, blowing out its back panels in a shower of sparks and flaming debris.

 

The Zero Pointer, a machine the size of a skyscraper, was dead on impact. It began to tilt backward, collapsing away from Uraraka and the trapped students.

 

But physics demands an equal and opposite reaction.

 

The safety limiters on Izuku’s O.D. Gauntlet were off. The kinetic recoil dampers had melted from the heat. The force of the strike, equivalent to several tons of TNT, had nowhere to go.

 

It traveled back through the metal fist, up the carbon-fiber arm, bypassed the melted titanium anchor points, and slammed directly into Izuku’s biological humerus and shoulder joint.

 

SNAP.

 

The sound of Izuku’s right arm breaking in three different places was sickeningly loud in his own ears. The bone snapped, the ligaments tore, and the shoulder dislocated with a violent, agonizing crunch.

 

Izuku screamed, his vision whiting out entirely from the sheer volume of pain signals flooding his NSI.

 

[SYSTEM FAILURE. CATASTROPHIC HARDWARE MELTDOWN. NEURAL LINK SEVERED.]

 

The red lights on his armor died. The HUD vanished.

 

Izuku was suddenly just a fourteen-year-old boy in a heavy, dead metal suit, falling from a height of two hundred feet with a shattered arm. The wind roared in his ears. He couldn't move his legs. The dead weight of the greaves was dragging him down faster.

 

‘I... I overdid it,’ Izuku thought, his consciousness slipping away into the pain. ‘I'm going to die.’

 

He closed his eyes, accepting the fall.

 

SMACK.

 

A soft, fleshy hand slapped him hard across the cheek.

 

Instantly, the terrifying sensation of falling vanished. Izuku opened his eyes slightly. He was hovering five feet above the ground, completely weightless.

 

Below him, Uraraka was standing on one leg, her hand outstretched, gasping for breath. She had managed to crawl out from under the rubble while the robot was falling and used the last dregs of her stamina to cast her Quirk on him.

 

"Release!" she wheezed, pressing her fingers together.

 

Gravity reasserted itself. Izuku dropped the remaining five feet, crashing heavily onto the asphalt. His broken arm flared with agony, and he let out a choked gasp, but he was alive.

 

Uraraka collapsed onto the ground next to him, vomiting a small rainbow from the nausea of her Quirk over-usage.

 

The battlefield was dead silent, save for the crackling of fires from the ruined Zero Pointer.

 

The remaining students slowly crept out from their hiding spots, their mouths hanging open in sheer disbelief. They looked at the mountain of smoking scrap metal, and then they looked at the boy lying in the cratered street.

 

His right arm armor was completely warped, the carbon fiber cracked and venting black smoke. Blood was trickling from his nose and the back of his neck where the NSI had overloaded. He looked broken.

 

But as Izuku Midoriya lay there, his vision fading to black, a faint, bloody smile crossed his lips.

 

He hadn't needed a Quirk. He had built a fist of iron, and he had punched a god in the face.

 

Then, the darkness took him.
