What if deku was a chronosapien

 

 

The ticking began when he was four years old.

 

Before the ticking, Izuku Midoriya was an ordinary boy with ordinary dreams. He lived in a world where the extraordinary had become mundane, where eighty percent of the global population possessed a genetic abnormality known as a "Quirk." Men could breathe fire, women could manipulate gravity, and children could sprout wings and take to the skies. Izuku, with his unruly mop of green hair and large, starry eyes, wanted nothing more than to join their ranks.

 

More specifically, he wanted to be like him.

 

In the dimly lit living room of the Midoriya apartment, the television screen cast a harsh, flickering glow across Izuku’s face. On the screen, a mountain of a man with golden hair was pulling civilians from the wreckage of a collapsed bridge, laughing a booming, fearless laugh. “Fear not, citizens! Hope has arrived! Because I am here!”

 

Izuku rocked back and forth, clutching an All Might action figure in his small, pudgy hands. "Mom! Mom! Play it again!"

 

Inko Midoriya smiled softly from the doorway, wiping her hands on a dish towel. She walked over, her own heart swelling at her son's boundless enthusiasm, and pressed a button on the remote. The video restarted. Izuku beamed, but as he leaned forward, a sudden, violent shiver racked his small frame.

 

He dropped the action figure. It clattered against the hardwood floor.

 

"Izuku?" Inko’s smile faltered. "Are you alright, sweetie?"

 

Izuku didn't answer. He couldn't. A searing, unimaginable heat was blooming in his chest. He gasped, clutching at his shirt. It didn't feel like a fever; it felt like he had swallowed a live coal.

 

"Mom..." he whimpered, his voice trembling.

 

Inko dropped the towel and rushed to his side, falling to her knees. When she placed a hand on his forehead, she gasped and yanked it back. His skin was blistering hot, but that wasn't what terrified her. His skin didn't feel like skin anymore. It felt rigid. Unyielding. Like sun-baked metal.

 

"Izuku! Oh my god, Izuku, what's happening?!"

 

The boy let out a horrific scream. The sound tore through the quiet apartment, raw and agonizing. Beneath his soft, pale flesh, something was fundamentally shifting. It wasn't just a genetic activation; it was a total biological rewrite.

 

Crack. Snap. Whir.

 

Inko watched in absolute, paralyzing horror as patches of Izuku’s skin began to flake away like dead ash, revealing gleaming, copper-colored plating underneath. His small, rounded shoulders broadened, squaring off into blocky, mechanical joints. The sound of snapping bones was replaced by the terrifying screech of grinding metal and the loud, rhythmic clack-clack-clack of internal gears meshing together for the first time.

 

"It hurts! Mom, it hurts!" Izuku wailed, but his voice was already distorting, taking on a strange, reverberating metallic echo.

 

His torso expanded, becoming heavy and barrel-like. A circular aperture opened violently in the center of his chest, glowing with a fierce, blinding green energy that pulsed in time with his racing heartbeat. His arms and legs grew thick and cylindrical, plated in heavy copper and brass-colored biomachinery. His soft green hair fell out in clumps, replaced by a smooth, domed, copper helm.

 

And then, with a sickening shhhh-clack, a large, ornate, wind-up key erupted from the top of his head, locking into place.

 

Izuku collapsed onto the floor. He didn't bounce. He hit the wood with a devastating, heavy THUD that shook the entire apartment. The floorboards splintered beneath his newfound, immense weight.

 

The screaming stopped. The apartment fell dead silent, save for a new sound.

 

Tick. Tock. Tick. Tock.

 

It was a deep, resonant sound, echoing from the glowing green glass of his chest cavity. It was the sound of a clock.

 

Inko, weeping hysterically, reached out and touched her son's cheek. It was cold, hard, and metallic. "Izuku?" she choked out.

 

Slowly, the boy's heavy copper eyelids fluttered open. Where there had once been large, emerald-green irises, there were now only solid, glowing green optical sensors. He looked at his hands—thick, clunky, three-fingered mechanical claws made of solid copper.

 

He tried to sit up, but the sheer weight of his own body pinned him down. The gears in his shoulders ground against each other in protest.

 

"Mom...?" The voice was his, yet completely alien. It sounded like it was being projected through a radio speaker. "Mom... I can't move. I'm so heavy."

 

Inko pulled her biomechanical son into her arms, weeping into the cold copper of his shoulder. The television behind them continued to play. All Might laughed, saving the day. But for Izuku Midoriya, the world had just stopped.

 

 

 

"The classification is Heteromorphic, with a powerful Emitter sub-type," Dr. Tsubasa said, adjusting his glasses as he looked at the X-rays illuminated on the lightboard.

 

Except, they weren't really X-rays. They looked more like blueprints.

 

Inko sat in the uncomfortable hospital chair, twisting a tissue into shreds. Beside her sat seven-year-old Izuku. He didn't sit in the chair; he sat on a reinforced steel stool the hospital had specifically brought in, because he had crushed the first two standard chairs he tried to sit on.

 

Izuku stared at his own internal scans. Where a heart should be, there was a complex network of glowing green chronal-energy conduits. Where lungs and a stomach should be, there were hundreds of interlocking brass and copper gears, ticking away in a perpetual rhythm.

 

"He is, for all intents and purposes, a biomechanical entity now," Dr. Tsubasa explained, tapping a pen against the glowing X-ray. "His cellular structure has completely transmuted into an unknown, highly durable metallic alloy. We haven't been able to scratch it with standard medical tools. His core—that glowing chest cavity—seems to generate a unique type of kinetic and temporal energy."

 

"Temporal?" Inko asked, her voice wavering.

 

"Time, Mrs. Midoriya. The boy's Quirk isn't just his body. That body is merely a vessel built to contain an immense, localized temporal field. We've decided to officially register his Quirk as 'Clockwork'."

 

Izuku looked down at his heavy, three-fingered hands. "Can I still be a hero?" he asked. The metallic reverberation in his voice was softer now, something he had slowly learned to control over the last three agonizing years, but it still lacked the warmth of a human child.

 

Dr. Tsubasa sighed, his expression turning sympathetic. "Izuku... your body weighs over four hundred pounds. Your joints are heavily armored, which provides incredible defense, but severely limits your mobility. Your top running speed is a fraction of a normal human's walking pace. If you overexert yourself, the friction in your internal gears generates catastrophic heat. You would literally melt from the inside out."

 

The words hit Izuku like a physical blow.

 

"Heroes need to be fast," the doctor continued gently. "They need to be agile. You are... well, you're a tank. A very slow, very heavy tank. I'm sorry, my boy. But the physical requirements for heroics are simply beyond your body's structural limits."

 

Izuku didn't cry. He physically couldn't. He lacked tear ducts. Instead, the glowing green light of his eyes dimmed, and the ticking in his chest slowed to a mournful, heavy rhythm.

 

Tick....... Tock....... Tick....... Tock.

 

 

 

Childhood is cruel, but children are crueler.

 

In a society built on the flashy, the powerful, and the heroic, a child who resembled a clunky, oversized grandfather clock was an easy target.

 

It was recess. The sun was shining on the playground sandbox. A young Katsuki Bakugo stood at the top of the jungle gym, small explosions popping playfully from his palms. He was a king holding court, surrounded by his lackeys.

 

Down below, Izuku was trying to catch up. He lumbered across the playground. Every step he took left a small indentation in the rubberized matting. Clank. Clank. Clank. The wind-up key on top of his head remained perfectly still.

 

"Hey, Katsuki! Wait for me!" Izuku called out, raising a heavy copper arm.

 

Bakugo looked down, his crimson eyes narrowing with childish arrogance. "Why would I wait for you? You take ten years just to cross the sandbox!"

 

"I'm hurrying!" Izuku protested, trying to force his gears to turn faster. He tried to break into a jog.

 

It was a mistake. As he pushed his heavy legs to move faster than their designed threshold, his center of gravity shifted abruptly. His foot caught on the edge of the sandbox. Because his joints lacked the micro-flexibility of human tendons, he couldn't catch himself.

 

He fell forward.

 

The impact was loud. A small cloud of sand exploded into the air as four hundred pounds of copper and brass slammed into the earth. Izuku lay there, face first in the sand, the heavy gears in his back whirring as he struggled to push himself up. He looked like a toppled statue.

 

The playground erupted into laughter.

 

Bakugo jumped down from the jungle gym, landing nimbly on his feet. He walked over to Izuku, who was still trying to find the leverage to right himself with his bulky arms. Bakugo sneered, placing a foot on the back of Izuku’s copper head, pinning him down effortlessly.

 

"Look at you," Bakugo mocked, the small pops in his hands sizzling near Izuku's audio receptors. "You can't even stand up on your own. You're useless. You're not even a real person anymore. You're just a broken wind-up toy."

 

"Kacchan, stop... please, let me up," Izuku's robotic voice pleaded, muffled by the sand.

 

"A broken toy needs a name," Bakugo declared to his laughing friends. "How about... Deku! Yeah. Deku! It means useless! The useless wind-up toy!"

 

Deku. Deku. Deku. The chant echoed across the playground.

 

Beneath Bakugo's foot, Izuku stopped struggling. The green light in his eyes flickered. He didn't feel anger; he just felt a hollow, crushing despair. The doctor was right. He couldn't be a hero. He couldn't even stand up.

 

He was just a machine. A slow, heavy, broken machine.

 

 

 

Ten years passed.

 

The boy became a teenager, though you couldn't tell by looking at him. His copper body didn't grow like normal human flesh. Instead, as he aged, his body shed its outer plating in a painful, molting-like process, revealing slightly larger, more refined copper armor underneath. He now stood at an imposing six feet tall, a hulking mass of steampunk machinery wearing a custom-tailored, oversized Aldera Junior High uniform that looked entirely ridiculous on him.

 

Inside the classroom, the teacher slammed a stack of papers onto his desk. "You guys are all third years now! It's time to start thinking seriously about your futures!"

 

He threw the papers into the air. "But who am I kidding? You're all aiming for the hero course, aren't you?!"

 

The class erupted into cheers, displaying a dazzling array of Quirks. Elongated fingers, glowing horns, small localized storms.

 

Izuku sat in the back corner. He sat perfectly still on his reinforced steel chair. He didn't cheer. He didn't raise his hand. He just stared straight ahead, the quiet tick-tock of his chest providing a constant, rhythmic backdrop to his existence.

 

"Hey, teach! Don't lump me in with these background characters!" Bakugo leaned back in his chair, feet on the desk, a feral grin on his face. "I'm going to U.A. High! I aced the mock test! I'm the only one here with the stuff to surpass All Might!"

 

"Ah, yes. Bakugo, you are aiming for U.A.," the teacher noted, looking at his clipboard. Then, he adjusted his glasses. "Oh, Midoriya. You're applying for U.A. too, right?"

 

The classroom went dead silent.

 

And then, a cacophony of laughter exploded.

 

"Deku?! You're kidding, right?!"

"The copper clock wants to be a hero?!"

"What's he gonna do? Bore the villains to death by walking at them really slowly?!"

 

Izuku didn't flinch. He was used to this. He slowly turned his heavy head toward his classmates. "The... rules changed," he spoke, his voice deep, mechanical, and steady. "There is... no rule against Heteromorphs... applying. I have... just as much right... to try."

 

BOOM!

 

An explosion rocked Izuku’s desk, shattering the wood. Bakugo stood over him, smoke rising from his palms. His face was twisted in absolute fury.

 

"Listen to me, you defective scrap heap!" Bakugo snarled. "You're even worse than the rest of these rejects! You don't just have a weak Quirk—your Quirk actively makes you worse than a Quirkless nobody! You can barely climb a flight of stairs without overheating! You think you can stand in the same ring as me?!"

 

Izuku looked up at Bakugo. His glowing green eyes were unreadable. The copper plating on his face allowed for no micro-expressions. No frowns, no scowls, no fear. Just a blank, impassive mask of metal.

 

"I am... going to try, Kacchan," Izuku said, his voice completely devoid of the panic he felt inside. It was a curse of his biology; no matter how terrified or anxious he was, he always sounded like a calm, calculating machine.

 

Bakugo scoffed, turning away. "Whatever. If you go to the exam, you'll probably just rust in the rain."

 

As the class ended and the students filed out, Izuku slowly gathered the charred remains of his notebook with his thick, three-fingered hands. Hero Analysis for the Future, No. 13. He carefully placed it into his oversized yellow backpack.

 

He stood up. The hydraulic hiss of his joints echoed in the empty room. He began his slow, lumbering walk home.

 

He hated his body. He hated the constant ticking. He hated that he couldn't feel the breeze on his skin, because he didn't have skin. He had read online forums about people with extreme Heteromorphic Quirks, about the body dysmorphia and the isolation. But at least a mutant with a lizard head still had flesh and blood. Izuku was entirely inorganic. He was a ghost haunting a suit of armor.

 

As he walked under a shadowy overpass, the rhythmic clanking of his footsteps echoing off the concrete walls, he muttered to himself. "I just want to save people. Why does it have to be so hard?"

 

Suddenly, the sewer grate beneath him exploded.

 

A horrific smell of sewage and rotting garbage filled the air. A massive, amorphous blob of dark green sludge erupted from the grate, towering over Izuku. Two massive, bulbous eyes and a jagged mouth formed in the fluid.

 

"A medium-sized meat suit!" the Sludge Villain gurgled. "Perfect! I need to hide!"

 

The villain lunged, wrapping his slimy, viscous body around Izuku. The sludge surged upward, trying to force itself down Izuku’s throat and into his lungs.

 

But Izuku didn't have a throat. And he didn't have lungs.

 

The Sludge Villain paused, its fluid body sliding off Izuku’s smooth, curved copper helm. "What the... what the hell are you?! Where is your mouth?! Where are your air holes?!"

 

Izuku stood there, mildly inconvenienced, covered in foul-smelling muck. He raised a heavy arm and grabbed a handful of the sludge, trying to pull it off his chest plate. "Let... go... of me," Izuku said, his voice buzzing with annoyance.

 

"You're not made of meat! You're solid metal!" The villain shrieked in frustration. "You're useless to me! I can't hijack a robot!"

 

"I am... not... a robot," Izuku replied calmly.

 

Before the villain could detach itself and flee, the manhole cover behind them was blasted into the sky. A massive figure stepped out of the shadows, radiating power and golden light.

 

"Have no fear, you copper-clad youth!" a booming voice echoed. "For I am here!"

 

Izuku’s optical sensors widened. The green light flared brightly. All Might.

 

"Texas..." All Might pulled his fist back, the sheer pressure of the air bending around his arm. "...SMASH!"

 

The wind pressure from the punch was like a localized hurricane. The Sludge Villain was instantly obliterated, scattered into a thousand droplets across the tunnel walls. The sheer force of the wind would have blown a normal teenager away, but Izuku’s four-hundred-pound frame barely shifted. He just stood there, his gears ticking rapidly as he stared at his idol.

 

All Might quickly gathered the scattered sludge into two empty soda bottles, securing them in his pockets. He turned to Izuku, flashing a dazzling smile. "Thank you for your accidental assistance, citizen! Your dense body perfectly distracted the villain! Now, I must be off!"

 

"Wait!" Izuku stepped forward, his heavy foot cracking the pavement. "Please! I... I need to ask you something!"

 

All Might crouched, preparing to leap. "I have no time, young man! Justice calls!"

 

"Can someone like me..." Izuku forced the words out, his vocal synthesizer straining with the emotion he was trying to convey. "...can a slow, heavy, broken machine... ever be a hero like you?!"

 

All Might paused. He looked at the boy. He took in the heavy copper plating, the massive gears visible in the joints, the cumbersome wind-up key on the head. The Number One Hero's smile softened slightly, turning into something more somber.

 

"Young man," All Might said, his voice losing some of its booming theatricality. "Pro heroes risk their lives every single day. The world of villainy is fast, brutal, and unforgiving. A hero needs speed to save civilians. They need agility to dodge lethal blows."

 

Izuku’s internal chronometer skipped a beat.

 

"Your body is incredibly durable, I can see that," All Might continued softly. "You would make an excellent police officer. Or a first responder in hazardous environments. They are heroes, too, in their own right. But to stand on the front lines against villains..." All Might shook his head. "I cannot, in good conscience, tell you that you can be a Pro Hero. You need to be realistic about your limitations."

 

The words echoed in the tunnel long after All Might had leapt into the sky, leaving a crater behind.

 

You need to be realistic.

 

Izuku stood alone in the dark. The ticking in his chest was deafening. It sounded like a countdown to nothing.

 

He didn't know how long he stood there. Ten minutes? An hour? His internal clock felt broken. Eventually, his programming—his basic human will to keep moving—forced his heavy legs into motion.

 

Clank. Clank. Clank.

 

He walked through the city, deaf to the bustling crowds around him. He felt hollow. The one person who could have validated his dream had driven the final nail into the coffin. Bakugo was right. The doctor was right. The whole world was right.

 

He was just Deku.

 

As he walked past a busy shopping district, a massive explosion shattered his reverie. Black smoke billowed into the afternoon sky just a few blocks away. Sirens wailed.

 

A crowd was gathering near Tatooin Shopping District. Izuku, running purely on autopilot, lumbered toward the commotion. Because of his height, he could easily see over the heads of the crowd.

 

What he saw made his core freeze.

 

The Sludge Villain had escaped. It was massive now, towering over the burning storefronts. And trapped within its viscous, churning body, struggling desperately for air, was Katsuki Bakugo.

 

Pro heroes were on the scene. Death Arms, Kamui Woods, Mt. Lady, and Backdraft. But they were doing nothing.

 

"We can't get close!" Death Arms shouted, shielding his face from the flames Bakugo was accidentally setting off. "The kid's Quirk is making it a minefield! And I don't have the right Quirk to grab the sludge!"

 

"I need two lanes for my size, I can't squeeze in there!" Mt. Lady yelled.

 

"We just have to wait for someone with a suitable Quirk!" Kamui Woods ordered.

 

Izuku stared. The heroes were waiting. They were just standing there, watching.

 

He looked at Bakugo. The ash-blonde boy was thrashing, his eyes wide with genuine, primal terror. Bakugo's eyes met Izuku's glowing green optics across the crowd. In that split second, Izuku didn't see the bully who had tormented him for ten years. He saw a boy begging for his life.

 

Izuku didn't think.

 

He didn't calculate his weight. He didn't consider his top speed. He didn't think about his overheating gears.

 

His heavy right foot stepped forward.

 

"Hey! You!" a police officer yelled, grabbing Izuku’s massive arm. "Get back! It's too dangerous!"

 

Izuku ignored him. He kept walking, dragging the officer a few feet before the man let go in shock.

 

Clank. Clank. Clank.

 

"What is that kid doing?!" Death Arms yelled. "Stop him! He's just a walking pile of scrap, he'll melt!"

 

Izuku tried to run. He pushed his heavy legs to move, leaning his massive upper body forward. It was a lumbering, agonizing march. The heat inside his chest began to spike. The friction of his hip joints ground loudly, a terrifying screech of metal on metal.

 

Move, he thought. Move faster! Why am I so slow?!

 

The Sludge Villain looked down and laughed. "You again?! The useless metal boy?! What are you going to do, walk at me to death?!"

 

Bakugo stared at Izuku, his mouth muffled by sludge, but his eyes screaming: What are you doing?! You're going to die!

 

Izuku reached into his backpack and threw his notebook. It bounced harmlessly off the villain's eye, doing absolutely nothing. He was still twenty feet away. He was too slow. Bakugo's eyes were rolling back into his head. The sludge was suffocating him.

 

No! Izuku screamed in his mind. No! I won't let him die! I don't care if I break! I don't care if I melt! MOVE!

 

Panic, pure, unadulterated human panic, surged through Izuku’s biomechanical nervous system. His glowing core shifted from a steady green to a blinding, searing white.

 

And then, something extraordinary happened.

 

The heavy, ornate key locked onto the top of Izuku’s head suddenly shifted. For ten years, it had remained perfectly stationary. Now, with a loud metallic SNAP, it began to turn.

 

Click-click-click-click-click!

 

The key spun furiously, winding up.

 

A massive, invisible dome of emerald energy exploded outward from Izuku’s core, expanding instantly in a fifty-meter radius. It washed over the heroes, the villain, Bakugo, and the crowd.

 

Instantly, the world lost its color. The bright blue sky, the red flames, the dark sludge—everything was washed out in a monochromatic, sepia-toned green filter.

 

And the noise stopped.

 

The roaring flames, the screaming crowd, the villain's laughter. Complete, absolute silence.

 

Izuku stumbled forward and nearly fell, his momentum carrying him into a world that was suddenly entirely static. He caught his balance and looked around.

 

The flames of the burning buildings were suspended in mid-air, frozen like jagged glass sculptures. A bird in the sky hung perfectly still, its wings caught mid-flap. Death Arms was frozen with his mouth open in a shout. The Sludge Villain was completely immobilized, a grotesque statue of muck.

 

The only sound in the entire world was the deafening, frantic ticking of Izuku’s own chest.

 

TICK-TOCK-TICK-TOCK-TICK-TOCK!

 

Izuku looked down at his hands. He was glowing with an intense, radiating green aura.

 

He didn't understand what was happening. He didn't know that in a moment of pure, selfless desperation, he had achieved a Quirk Awakening. He had unconsciously activated an incredibly rare, god-tier temporal anomaly.

 

The Sotobro Effect.

 

He had completely stopped the flow of time within a localized radius.

 

"I'm... moving," Izuku whispered. His voice didn't echo. Sound waves couldn't travel normally through frozen time; he only heard himself through the internal vibrations of his own chassis.

 

He looked at Bakugo, whose terrified expression was perfectly preserved in the sludge.

 

Izuku didn't waste a single, precious second. He knew, instinctively, that this wouldn't last. The heat building in his core was astronomical. His internal temperature alarms were screaming in his HUD, flashing bright red warnings across his optical sensors.

 

He lumbered forward. He closed the twenty-foot gap, his heavy footsteps making no sound on the frozen pavement.

 

He reached the Sludge Villain. He grabbed the sludge surrounding Bakugo. To Izuku, the liquid didn't feel like liquid anymore. Because time was stopped, the fluid dynamics were frozen. The sludge felt like dense, squishy clay.

 

Izuku planted his heavy copper feet into the ground. He dug his thick, three-fingered claws into the dense muck around Bakugo's torso.

 

Grind. Screech.

 

The gears in Izuku’s arms wailed in protest as he physically tore the frozen sludge apart. It was like tearing through solid rubber. Sparks flew from his elbow joints as he pulled with all his mechanical might.

 

With a sickening, silent pop, he ripped Bakugo free from the villain's grasp.

 

Izuku slung the frozen, unconscious boy over his heavy shoulder. Bakugo felt weightless compared to Izuku’s own chassis.

 

WARNING. CORE TEMPERATURE CRITICAL. STRUCTURAL MELTDOWN IMMINENT.

 

The red text flashed violently in Izuku’s vision. Steam was violently venting from the gaps in his copper armor. He could feel his internal gears beginning to warp from the heat.

 

He turned around and marched away from the villain, carrying Bakugo back toward the safety of the Pro Heroes. Every step was agony. His body felt like it was submerged in magma.

 

He reached Death Arms. He carefully deposited Bakugo on the ground at the hero's feet.

 

Izuku stood up straight. The key on his head stopped spinning.

 

Click.

 

The sepia-green filter shattered like glass. Color flooded back into the world.

 

"-ING! STOP HI—wait, what?!" Death Arms' shout resumed seamlessly, but he stumbled backward in shock, nearly tripping over Bakugo, who was suddenly gasping and coughing on the ground in front of him.

 

"What the hell?!" Mt. Lady shrieked, rubbing her eyes.

 

"Where did the kid go?!" Kamui Woods yelled.

 

The Sludge Villain, suddenly realizing it was holding nothing but empty air, roared in confusion. "Where is he?! Where did the brat go?!"

 

The heroes, the villain, and the crowd stared in absolute bewilderment. One millisecond ago, Bakugo was fifty feet away, trapped inside a monster, and a weird metal kid was walking toward him. In the blink of an eye, literally faster than a human could perceive, Bakugo was safe on the ground, and the metal kid was standing right there.

 

"It's teleportation!" someone in the crowd yelled. "The kid has a warp Quirk!"

 

Izuku couldn't hear them.

 

The moment time resumed, the temporal backlash hit him. The astronomical heat generated by forcing his mechanical body to operate outside the boundaries of normal physics caught up to him.

 

A massive hiss of scalding white steam erupted from every seam, joint, and exhaust port on Izuku’s body. The green light in his eyes flickered violently, turning a sickly yellow, then red, before dying out completely.

 

"I... saved him," Izuku's vocal synthesizer crackled, distorting heavily.

 

His heavy knees buckled.

 

Four hundred pounds of superheated copper crashed onto the pavement. Izuku Midoriya's systems initiated an emergency shutdown to prevent his core from detonating. His world faded to black.

 

 

 

High above the street, standing on the edge of a building, a skeletal, blond man coughed violently into his hand.

 

Toshinori Yagi, the man known as All Might, stared down at the alleyway with wide, unbelieving eyes.

 

He had arrived at the scene just as the Sludge Villain had captured the Bakugo boy. He had cursed himself, clutching his bleeding side, knowing he had expended his time limit. He had watched in shame as the Pro Heroes did nothing, and he had watched in shock as the heavy, biomechanical boy he had rejected earlier stepped forward.

 

But Toshinori Yagi was not a normal man. He wielded One For All, a Quirk of unimaginable power, cultivating the strength of eight previous users. And because of the residual, lingering presence of those past users within his soul, Toshinori possessed a terrifyingly high perception of reality.

 

When the world had turned sepia-green, Toshinori hadn't been completely frozen.

 

His physical body was locked in time, yes. He couldn't move a muscle. But his consciousness, anchored by the vestige realm of One For All, remained active.

 

He had watched, trapped in his own frozen body, as the heavy, copper boy slowly, painfully marched through a world standing perfectly still. He had watched the boy rip solid sludge apart, carry his bully to safety, and stand tall.

 

Toshinori’s heart hammered against his ribs. He didn't teleport, Toshinori realized, awe washing over him. He stopped time. He literally stopped time itself.

 

Toshinori looked at his own scarred hands. He had been looking for a successor. Someone brave. Someone selfless. He had assumed he needed someone with the physical constitution to inherit his strength.

 

But as he looked down at the unconscious, smoking metal boy being sprayed with coolant by the fire department, Toshinori realized how blind he had been.

 

That boy... his body is a prison. A heavy, agonizing prison. And yet, he possesses a power that dwarfs even my own. But it's killing him to use it.

 

Toshinori wiped the blood from his mouth. A new smile formed on his gaunt face. Not the theatrical smile of All Might, but the genuine smile of Toshinori Yagi.

 

"I was wrong about you, young man," he whispered to the wind. "I was so very wrong."

 

 

 

"Are you insane?!"

 

The reprimand was deafening. Izuku’s optical sensors slowly booted up, bathing the world in a dim, pulsing green light. He was sitting on the back of an ambulance, an oxygen mask uselessly strapped to his smooth, mouthless face by a well-meaning but confused paramedic.

 

Death Arms was standing over him, his face red with anger. "You have a death wish, kid?! What if you had teleported him into a wall?! What if your Quirk misfired?! You leave the heroics to the professionals! You just got in the way!"

 

Izuku didn't argue. He just sat there, his head down, the key on his head completely still. His body ached in a way he didn't know machinery could ache. His joints felt warped, stiff, and brittle.

 

A few yards away, the heroes were praising Bakugo.

 

"What an incredible Quirk!" Kamui Woods was saying. "You held out so long! You're going to make a fantastic hero one day!"

 

Bakugo didn't look happy. He was wrapped in a blanket, glaring at the ground. He slowly raised his head and locked eyes with Izuku. For the first time in his life, Katsuki Bakugo didn't sneer. He just stared, a complex storm of anger, confusion, and bruised pride swirling in his crimson eyes. He opened his mouth to say something, but snapped it shut and looked away.

 

Eventually, the heroes let Izuku go, writing him off as a suicidal kid with a flashy but suicidal warp Quirk.

 

The walk home took hours. Izuku’s internal battery was critically low. His right leg dragged slightly, a gear in his hip having cracked from the thermal expansion.

 

Clank... scrape... Clank... scrape...

 

The sun was setting, casting long, dramatic shadows across the quiet suburban streets. Izuku felt miserable. He had saved Kacchan, yes, but at what cost? He had nearly melted his own core. The heroes had yelled at him. Nothing had changed. He was still Deku. A broken toy that had just wound itself up a little too tight.

 

"I am here!"

 

Izuku stopped. He slowly turned his heavy torso around.

 

Standing at the intersection, completely blocking the path, was All Might. The Number One Hero was not smiling his usual boisterous grin. He looked serious.

 

"All... Might?" Izuku’s voice crackled, his vocal synthesizer damaged from the heat. "What are... you doing here? Did you... come to yell... at me too?"

 

"No," All Might said, taking a step forward. Suddenly, steam erupted from the hero's massive body. Izuku watched in shock as the hulking, golden-haired god rapidly deflated, shrinking down into a gaunt, skeletal man with sunken eyes and baggy clothes.

 

Izuku took a step back, his gears grinding in alarm. "Wh-What?! Who are you?! Where did All Might go?!"

 

"I am All Might," the skeletal man said, blood dripping from his chin. "This is... my true form. An injury I sustained five years ago severely limits the time I can spend as a hero."

 

Izuku’s encyclopedic knowledge of heroes immediately linked the date to a massive, classified battle. But before he could compute the data, All Might held up a hand.

 

"Young man," Toshinori said, his voice quiet but commanding. "I owe you a profound apology."

 

Izuku froze. "An... apology?"

 

"Earlier today, I told you to be realistic. I looked at your heavy, armored body, and I judged you based on traditional metrics of heroism. I told you that you could not stand on the front lines." Toshinori took a deep breath. "I was a fool. And a hypocrite."

 

Toshinori walked up to Izuku. He didn't look at the intimidating copper armor, or the strange, glowing green core. He looked straight into the boy's optical sensors.

 

"When that villain had the Bakugo boy," Toshinori said, his voice trembling slightly, "I was terrified. I was out of time. I couldn't move. The other heroes were paralyzed by their own inadequacies. But you... you, who had been told by everyone, including myself, that you were inadequate..."

 

Toshinori pointed a bony finger at Izuku’s chest.

 

"...you stepped forward. And you did something incredible."

 

"I... I don't know what I did," Izuku admitted, his metallic voice barely a whisper. "I just... I wanted to save him. And suddenly, the world stopped."

 

"I know," Toshinori smiled, a genuine, warm expression. "My Quirk... it allows me to perceive things that others cannot. I saw what you did. You didn't teleport, young man. You stopped time."

 

Izuku stared at him. The ticking in his chest hitched. Stopped time?

 

"Your Quirk is not a curse, my boy," Toshinori said, placing a gentle hand on Izuku’s cold, copper shoulder. "It is a power of unimaginable magnitude. But you are right... your body, as it is now, cannot handle the strain of that power. It requires discipline. It requires upgrading. It requires training."

 

Toshinori locked eyes with Izuku.

 

"You asked me if a slow, heavy machine could be a hero."

 

Toshinori smiled, tears pricking his sunken eyes.

 

"Young man... you too, can become a hero."

 

Izuku’s breath caught—or rather, his ventilation fans seized. The words hit him with the force of a Detroit Smash. It was the one thing he had wanted to hear his entire life. It was the one phrase he had begged his mother to say, begged the doctor to say, begged the world to say.

 

He fell to his knees. The concrete cracked under the weight.

 

He didn't have tear ducts. He couldn't cry like a normal human. But as the overwhelming wave of emotion crashed over him, his internal systems responded. The green optical fluid that lubricated his sensors overflowed, leaking from the corners of his glowing eyes, trailing down his smooth copper cheeks like glowing, neon tears.

 

He gripped the fabric of his trousers with his heavy claws, burying his face in his hands, his broad metal shoulders shaking violently. A strange, metallic, echoing sob tore from his vocal synthesizer.

 

It wasn't the sound of a broken wind-up toy.

 

It was the sound of a hero's gears, finally clicking into place.

 

 

The morning after the Sludge Villain incident, Izuku Midoriya did not wake up. He booted up.

 

It started deep within the barrel-like chassis of his chest. The glowing green chronal core, which had dimmed to a dull, sickly yellow during his emergency shutdown, sparked. A low, resonant hum vibrated through his reinforced ribs, followed by the slow, rhythmic click-clack of his primary gears engaging.

 

Tick... Tock... Tick... Tock.

 

Izuku’s optical sensors flickered, bathing his dark bedroom in a soft, emerald light. He tried to sit up, but a sharp, localized screech of grinding metal echoed from his right shoulder joint.

 

"Warning: Thermal damage detected in right primary actuator," his internal HUD flashed across his vision in a stream of red, digital text.

 

He moved his arm slowly, wincing as the damaged gear protested. The sheer amount of heat he had generated yesterday by freezing time had warped his copper plating and partially fused some of his secondary cooling fans. His mother, Inko, had spent three hours the night before carefully applying industrial-grade mineral oil to his joints with a rag, crying the entire time.

 

Despite the ache in his metal bones, despite the looming repair costs, a feeling of profound, alien warmth blossomed in Izuku’s chest. It wasn't the dangerous heat of a core meltdown. It was hope.

 

“You too, can become a hero.”

 

The words echoed in his audio receptors, replaying from his internal memory banks in perfect, lossless audio. All Might had seen him. The Number One Hero had seen the lumbering, heavy, broken machine, and recognized a hero.

 

Izuku slowly swung his massive legs out of bed. His heavy, three-fingered feet hit the floorboards with a dull thud. He stood, his joints hissing as hydraulic pressure equalized. He grabbed an oversized sweatshirt—custom-tailored to fit over his bulky, four-hundred-pound frame—and made his way to the front door.

 

He had a meeting.

 

 

 

Dagobah Municipal Beach Park was a graveyard.

 

Years of illegal dumping, carried by the ocean currents and negligent citizens, had turned the once-beautiful coastline into a sprawling mountain range of rusted refrigerators, crushed cars, broken electronics, and decaying tires. It smelled of salt, rot, and oxidized iron.

 

When Izuku arrived, the sun was just beginning to peek over the horizon. Standing at the edge of the seawall, looking impossibly frail in his baggy white t-shirt and cargo pants, was Toshinori Yagi.

 

"Ah! You made it, young Midoriya!" Toshinori called out, though he descended into a fit of hacking coughs immediately after.

 

Izuku lumbered down the concrete steps to the sand. His weight caused his feet to sink deep into the beach, making every step a grueling effort. Clank. Squelch. Clank. Squelch.

 

"I'm here, All Might," Izuku said, his voice buzzing through his vocal synthesizer. "But... why here? Are we going to train by cleaning the beach?"

 

"Astute as always!" Toshinori smiled, wiping a speck of blood from his chin. He gestured to the mountains of trash. "This is a cornerstone of my 'Aim to Pass: American Dream Plan!' However..." The skeletal man turned to Izuku, his expression turning serious. "...I originally brought you here with a different intention in mind. I need to explain something very important to you."

 

Toshinori sat down on the hood of a rusted-out sedan. "My Quirk, One For All, is a sacred torch passed down from generation to generation. It is the crystallization of power. I had intended, upon seeing your heroic spirit, to pass this Quirk on to you."

 

Izuku’s internal fans whirred to life, a physical manifestation of his shock. "Pass... your Quirk? To me? But Quirks are genetic! You can't just transfer them!"

 

"Mine is the exception," Toshinori said. "But... after consulting with an associate of mine who understands the biological mechanics of Quirks, I realized a terrible truth. I cannot give it to you."

 

Izuku’s optical sensors dimmed slightly. "Because I'm a machine?"

 

"Because your body lacks the biological foundation to absorb the Quirk factor," Toshinori explained gently. "One For All requires muscle fiber, cellular division, and a human nervous system to anchor itself. Your body is entirely comprised of an unknown, biomechanical alloy. If you ingested my DNA to transfer the Quirk, your internal chronal core would likely recognize it as a foreign biological contaminant and incinerate it. Or worse, the pure kinetic energy of One For All would violently clash with your temporal energy, causing your chassis to detonate."

 

Izuku looked down at his heavy copper hands. He didn't feel the crushing disappointment he expected. Instead, he felt a strange sense of clarity.

 

"I understand," Izuku said, the metallic reverberation of his voice steady. "And honestly... I don't want it."

 

Toshinori blinked in surprise. "You don't?"

 

"For ten years, I hated this body," Izuku confessed, his glowing green eyes scanning the heavy plating of his arms. "I hated the ticking. I hated being slow. I wished I was normal. But yesterday... yesterday, my body saved Kacchan. This core... this power... it's mine. I don't want to borrow someone else's strength. I want to learn how to be a hero with the body I was born with. I want to wind my own gears."

 

Toshinori’s sunken eyes widened, and then he threw his head back and laughed—a hearty, genuine laugh that didn't end in blood. "Well said, young Midoriya! Well said! That is exactly the spirit I am looking for!"

 

Toshinori stood up and gestured to the mountains of trash. "Then we begin! The entrance exam for U.A. High is in exactly ten months. For a normal boy, I would have them physically haul this trash to build muscle. But you weigh four hundred pounds and are made of solid metal. Muscle is irrelevant to you."

 

"So, what's the plan?" Izuku asked, his key twitching slightly.

 

"Your weakness is not a lack of strength, but a lack of thermal capacity," Toshinori instructed, tapping a finger against Izuku’s chest plate. "When you stopped time yesterday, you overheated in seconds. Your internal hardware couldn't handle the output of your core. So, we are going to force your body to adapt. Just like muscles tear and rebuild stronger, we are going to safely, repeatedly push your core to its thermal limit, forcing your metallic structure to temper, harden, and expand its capacity!"

 

Toshinori pointed to a massive pile of rusted washing machines and scrap metal.

 

"You are going to clear this beach using nothing but your Quirk! You will master the flow of time!"

 

Izuku looked at the towering pile of trash. He raised his right hand. He had never intentionally used his Quirk for anything other than absolute, terrifying emergencies.

 

"How do I... do it?" Izuku asked.

 

"Feel the ticking," Toshinori guided, stepping back. "Focus that energy into your limbs. You control time, my boy. Forward, backward, pause. Command it."

 

Izuku closed his eyes—or rather, shuttered his optical lenses. He listened to the rhythmic thrum of his chest. Tick. Tock. Tick. Tock. He imagined that rhythm accelerating. He imagined the gears spinning faster.

 

A deep, golden-green light began to pool in his three-fingered palm. The air around his hand began to shimmer, rippling like heat off asphalt.

 

He thrust his hand forward.

 

A concentrated beam of pure, golden-green chronal energy erupted from his palm. It wasn't a destructive laser; it made no sound of explosion. Instead, it emitted a rapid-fire ticking noise, like a thousand stopwatches running at once.

 

The beam struck a rusted, 1980s-era refrigerator.

 

Instantly, the metal began to decay. The remaining white paint peeled and flaked away in milliseconds. The rust spread like a virus, chewing through the steel. The plastic handle yellowed, cracked, and turned to dust. In the span of three seconds, the refrigerator underwent fifty years of accelerated weathering.

 

With a soft crump, the entire appliance collapsed into a pile of fine, red, oxidized dust.

 

Toshinori’s jaw dropped. "Good heavens..."

 

Izuku stared at his hand in awe. But immediately, a wave of heat washed over his internal sensors. A small jet of steam hissed from his shoulder joint.

 

"Again!" Toshinori shouted, recovering his composure. "Push it! Clear the pile!"

 

Izuku fired again. And again. Golden beams of accelerated time lashed out across the beach. A wrecked car rusted into a skeleton, its tires rotting into sludge and then drying into powder. A pile of old televisions crumbled into glass sand and degraded plastic.

 

But with every blast, the heat inside Izuku grew.

 

By the thirtieth blast, his copper armor was glowing a dull cherry red. His cooling fans were screaming, sounding like jet engines. The water trapped in the damp sand beneath his feet was instantly vaporizing, engulfing him in a cloud of steam.

 

"Warning! Core temperature at 85%!" his HUD screamed.

 

"I... I'm burning up!" Izuku cried out, his voice distorting heavily.

 

"Stop!" Toshinori ordered.

 

Izuku cut the energy. He collapsed onto his hands and knees in the sand, massive plumes of white steam violently venting from the grates on his back. His metal body hissed and popped as it cooled in the morning ocean breeze.

 

Toshinori walked over, carrying a massive, five-gallon jug of industrial distilled water. He poured it directly over Izuku’s back. The water flash-boiled on contact, sending up a massive geyser of steam, but rapidly drawing the heat out of Izuku’s chassis.

 

"That is your limit," Toshinori said, marking a clipboard. "Thirty localized temporal acceleration blasts before critical overheating. Tomorrow, we aim for thirty-one. Rest, cool down, and then we try something different."

 

Once his core temperature returned to normal, Izuku stood up.

 

"You accelerated time to age the trash into dust," Toshinori said. "Now, I want you to try the opposite. Rewind it."

 

Izuku approached a shattered, water-logged television set half-buried in the sand. He held out his hand. This time, he focused on reversing the rhythm in his chest. He imagined the gears turning backward.

 

A beam of pale, cyan-blue light shot from his palm.

 

When it hit the television, the effect was mesmerizing. The shattered shards of glass scattered in the sand violently trembled before flying backward, reassembling themselves into a pristine cathode-ray tube. The waterlogged wood dried out and regained its polish. The rusted internal wires gleamed with fresh copper.

 

In five seconds, the television looked like it had just been unboxed from a factory in 1998.

 

Izuku gasped, amazed at his own power. But the physical toll was identical. The heat spiked.

 

"Acceleration and Retrocognitive Reversal," Toshinori muttered, feverishly writing in a notebook. "The combat and support applications are limitless. If you can age an opponent's weapons to dust, or rewind structural damage... young man, you are a walking miracle."

 

"But I'm still so slow," Izuku said, looking at his heavy legs. "If a villain just runs away from me, I can't catch them."

 

"Then we will train your aim!" Toshinori declared. "You will not be a brawler who chases villains down. You will be a walking fortress! An artillery battery of time! And if they get close... well, we'll cross that bridge when your core can handle the Sotobro Effect again."

 

 

 

The ten months of training were a grueling, metallic hell.

 

Izuku did not build muscle, but his body underwent a profound transformation. As he constantly pushed his chronal core to the brink of a meltdown and cooled it down, the intense thermal cycling began to temper his biomechanical structure.

 

Around month four, Izuku experienced a terrifying phenomenon. His outer layer of copper armor began to crack and peel away, revealing a slightly darker, infinitely denser alloy underneath—a rich, deep bronze. His body was essentially molting, shedding the weaker metal for a chassis capable of containing his growing power. His internal gears grew thicker, the teeth biting together with a sharper, heavier clack.

 

By month seven, he was no longer carrying jugs of water to cool down. His internal fans had upgraded themselves, venting heat with the force of a wind tunnel. He could fire two hundred localized time rays before reaching critical temperature.

 

He also practiced the Sotobro Effect—the full stoppage of time. It remained his most dangerous ability. He could only hold the world perfectly still for a maximum of three seconds in real-time (which felt like thirty seconds in frozen time) before his core threatened to detonate. The heat generated by freezing the universe was astronomical. It was a trump card, to be used only in life-or-death situations.

 

Through it all, his bond with Toshinori grew. The skeletal man didn't treat him like a broken toy. He treated him like a weapon that needed honing, like a hero in the making. They spent hours on the beach, with Toshinori tossing debris into the air and Izuku practicing his quick-draw, blasting the trash into dust before it hit the ground.

 

Finally, the morning of the U.A. Entrance Exam arrived.

 

Toshinori stood at the edge of the seawall. The sun rose over Dagobah Beach, reflecting brilliantly off the pristine, white sand. There was not a single speck of trash left. Everything had either been aged into elemental dust or rewound into pristine scrap and hauled away by recycling trucks.

 

Standing in the center of the clean beach was Izuku.

 

He was taller now, standing a formidable six-foot-two. His body was a masterpiece of steampunk biology. His armor was a gleaming, tempered bronze with heavy brass accents. The gears visible in his joints were thick and robust. The glowing green core in his chest pulsed with a steady, powerful rhythm. The key on his head gleamed in the sunlight.

 

Tick. Tock. Tick. Tock.

 

Izuku looked at his hands, then up at All Might. "I did it."

 

"You did, young Midoriya," Toshinori smiled, his eyes shining with pride. "Your vessel has been forged. Your gears are wound. Now... it is time to show the world what the Master of Time can do!"

 

 

 

U.A. High School was massive, a towering monument of glass and steel shaped like an 'H'.

 

As Izuku lumbered up the main walkway, he drew stares. It was impossible not to. In a sea of teenagers in standard middle school uniforms, Izuku looked like a mechanized golem. Every step he took on the pavement echoed with a heavy CLANK, vibrating through the soles of the students around him.

 

"Whoa, look at that guy..."

"Is he a cyborg? Or a full-body mutant?"

"He looks so heavy. Think he can even run?"

 

Izuku ignored the whispers. He was used to them. He kept his optical sensors focused on the entrance.

 

Suddenly, a familiar, explosive voice barked behind him. "Out of my way, Scrap Heap!"

 

Izuku stopped and turned slowly. Katsuki Bakugo was stalking up the path, hands shoved deep into his pockets, his face locked in an angry scowl. Since the Sludge Villain incident, Bakugo hadn't actively bullied Izuku. The humiliation of being saved by the 'useless toy' had severely damaged Bakugo's pride. But he was still hostile.

 

"Good morning, Kacchan," Izuku said politely, his vocal synthesizer deep and resonant.

 

Bakugo clicked his tongue, refusing to make eye contact. "Don't think just because you have some flashy parlor trick you can stand on the same stage as me, Deku. You're still too slow to be a real hero."

 

Bakugo shoved past him, purposely bumping his shoulder against Izuku’s massive bronze arm. Bakugo winced slightly at the impact—hitting Izuku was like punching an anvil—and stalked off into the building.

 

Izuku watched him go. He turned back toward the entrance, but as he shifted his weight, his heavy foot caught the lip of the concrete step.

 

Because of his sheer mass and limited joint flexibility, a trip was catastrophic. Izuku felt his center of gravity plummet. Four hundred pounds of bronze and brass plummeted toward the pavement. He braced himself, knowing the impact would likely crack the concrete.

 

But the impact never came.

 

Instead, he stopped inches from the ground, floating weightlessly in mid-air.

 

"Oh! Sorry about that! I used my Quirk on you!"

 

Izuku slowly rotated his massive torso. Standing behind him was a girl with a round face, rosy cheeks, and short brown hair. She had her hand pressed against his bronze back.

 

"You're... really heavy!" she strained, her face flushing slightly. "It took a lot of effort to catch you! But it's bad luck to fall on exam day, right?"

 

Izuku carefully righted himself, placing his feet gently on the ground. The girl pressed her fingers together, and the crushing weight of gravity slammed back down upon his chassis. CLANK.

 

"Thank you," Izuku said. "I am... not very agile."

 

The girl smiled brightly. "I'm Ochaco Uraraka! Wow, your Quirk is so cool! You look like a steampunk robot!"

 

"Izuku Midoriya. And... thank you. I am a chronosapien."

 

"Chrono-what?" she tilted her head.

 

"Time," Izuku buzzed softly. "I manipulate time."

 

Uraraka's eyes widened, but before she could ask more, the warning bell for the written exam rang out across the campus. "Oh no! We're gonna be late! See ya inside, Midoriya!" She jogged off, waving back at him.

 

Izuku watched her go, a strange, warm feeling unrelated to his thermal core blooming in his chest. I talked to a girl. And she didn't call me a broken toy.

 

 

 

The written exam was easy. Izuku’s internal processors and mechanical memory made recalling historical dates and mathematical formulas trivial.

 

The real challenge was the orientation for the practical exam.

 

Sitting in the massive, darkened auditorium, Izuku listened as the Voice Hero, Present Mic, explained the rules on the giant screen. It was a mock urban battle. Examinees would be dropped into a replica city and tasked with destroying three types of robotic 'villains,' each worth one, two, or three points.

 

"Your goal is to use your Quirks to incapacitate the faux villains and rack up points! But beware! There is also a Zero Pointer, a massive obstacle that you should avoid at all costs!" Present Mic yelled.

 

Izuku sat in his reinforced chair, his gears quietly ticking. A speed and destruction test. The absolute worst-case scenario for my mobility. The speedsters will destroy all the targets before I can even walk halfway down the street.

 

He began to calculate trajectories, spawn rates, and optimal interception paths, muttering to himself. Because of his metallic vocal cords, his muttering didn't sound like a whisper; it sounded like a swarm of angry, buzzing bees trapped in a tin can.

 

"Bzzzt... if the spawn rate is localized to the perimeter, then moving to the center intersection provides a 360-degree firing line... bzzzt... calculating the optimal thermal venting time between chronal blasts... bzzzt..."

 

Suddenly, a tall boy with glasses and blue hair stood up in the row ahead of him, pointing stiffly.

 

"You! The large, metallic individual in the back!" The boy shouted. "Your mechanical buzzing is incredibly distracting! If you are not taking this seriously, then leave immediately!"

 

Izuku stopped buzzing. The glowing green lights of his eyes narrowed slightly. "I apologize. I was... calculating my combat trajectory."

 

"See that you calculate quietly!" the boy chopped the air with his hand and sat down.

 

Bakugo, sitting a few rows down, scoffed loudly. "Stupid Deku."

 

 

 

Ten minutes later, the examinees were gathered before the towering gates of Battle Center B.

 

Izuku stood at the back of the pack. He looked at the lithe, athletic teenagers around him stretching their muscles and bouncing on their toes. The blue-haired boy was doing high-knees. Uraraka was taking deep breaths.

 

"Right, let's start!" Present Mic's voice boomed from the watchtower. "There are no countdowns in real battles! Run, run, run!"

 

The massive metal gates slammed open.

 

Instantly, the crowd of teenagers surged forward like a tidal wave, rushing into the mock city with superhuman speed, jumping off walls, and flying through the air.

 

Izuku did not run. He couldn't.

 

He stepped forward. Clank.

 

"Hey! Heavyweight! You're falling behind!" Present Mic's voice echoed, clearly teasing him.

 

Izuku ignored the commentary. He fell into a steady, lumbering march. Clank. Clank. Clank. By the time he actually crossed the threshold of the gate, the sounds of explosions and crushing metal were already echoing from deep within the city. The fast Quirks were already racking up points.

 

He walked down the main avenue. The street was littered with the wrecked chassis of One and Two-Pointer robots, destroyed by Bakugo, Iida, and the others. There was nothing left for him here.

 

"They are clearing the perimeter," Izuku analyzed aloud. "I must reach the center."

 

He pushed his leg servos slightly past their standard operating capacity. His march turned into a heavy, earth-shaking jog. The friction in his joints immediately began to build heat, but he pushed through it, relying on his training at the beach to manage the thermal load.

 

He reached the central intersection of the mock city—a massive, open plaza surrounded by tall, faux-concrete buildings.

 

A Three-Pointer robot, resembling a massive, tread-driven tank, rounded the corner. Its optical sensor locked onto Izuku.

 

"Target acquired!" the robot synthesized, raising a heavy missile launcher.

 

Izuku didn't flinch. He planted his heavy bronze feet into the pavement, adopting a wide, immovable stance. He raised his right arm, pointing his three-fingered hand directly at the charging machine.

 

Tick-tock-tick-tock!

 

The gears in his chest spun to life. The golden-green light pooled in his palm.

 

"Accelerate," Izuku commanded.

 

A searing beam of chronal energy erupted from his hand. It struck the Three-Pointer directly in its center mass.

 

The robot didn't explode. It didn't fly backward. Instead, it simply stopped moving. The pristine, silver metal of its chassis instantly dulled, oxidized, and bloomed with deep red rust. The synthetic rubber of its treads cracked and disintegrated into dry powder. The structural integrity of its armor failed entirely.

 

With the momentum of its own charge, the heavily rusted machine collapsed under its own weight, shattering into a massive pile of flaky red dust and brittle, corroded wires.

 

"Three points," Izuku noted calmly.

 

A whirring sound caught his attention. Two Two-Pointers were flanking him from the left alleyway, while another Three-Pointer emerged from the right.

 

Izuku didn't run. He realized something profound: he was a turret. If he positioned himself correctly, he didn't need to chase them. They would come to him.

 

He raised both hands.

 

Tick-tock-tick-tock!

 

Golden beams lashed out across the plaza. Izuku pivoted at the waist, moving like a heavy tank turret. Every robot the beams touched instantly aged into oblivion, collapsing into dust.

 

"Seven points. Ten points. Fifteen points," Izuku counted.

 

In the observation room high above the city, the U.A. teachers stared at the monitors in absolute silence.

 

"What is that?" the R-Rated Hero, Midnight, asked, her eyes wide. "He's not destroying them with brute force. He's rotting them."

 

"Fascinating," Nezu, the principal, chimed in, taking a sip of tea. "It appears to be localized temporal acceleration. He is aging the faux villains until their components fail. A terrifyingly potent Quirk. But look at his thermal readings."

 

On the screen, a thermal overlay of Izuku showed his internal core glowing a bright, dangerous red.

 

Down in the plaza, Izuku was feeling the burn. He had racked up forty points, acting as an impenetrable anti-air and anti-armor battery. But the heat was building. Steam was whistling furiously from the grates on his back and shoulders. The air around him shimmered with the heat mirage.

 

"Warning. Core temperature 75%. Recommend immediate cessation of chronal output," his HUD warned.

 

I need a few more points to be safe, Izuku thought, his mechanical vision slightly blurred by the internal heat. Just a few more.

 

Suddenly, the ground shook.

 

It wasn't a small tremor. It was a localized, devastating earthquake. The pavement beneath Izuku’s feet cracked and heaved.

 

At the far end of the main avenue, the buildings shattered like glass as a monolithic, impossibly large shadow eclipsed the sun. The Zero Pointer. It was the size of a skyscraper, a terrifying behemoth of steel and treads that crushed entire city blocks as it rolled forward.

 

"Obstacle deployed!" Present Mic announced over the speakers.

 

Panic erupted in the streets. The examinees, who had been confidently destroying smaller robots seconds before, turned and fled in absolute terror.

 

"Run away!"

"That thing is insane! It's going to crush us!"

"Retreat!"

 

Izuku watched the mass exodus. The logical part of his brain—the part governed by processors and survival instincts—told him to turn around and lumber away. He had forty points. It was likely enough to pass.

 

He initiated his turning sequence.

 

But over the deafening roar of grinding metal and collapsing buildings, his highly sensitive audio receptors picked up a sound.

 

A human cry.

 

Izuku’s head snapped back around. Through the dust and debris billowing from the Zero Pointer's path, his optical zoom engaged, magnifying his vision by ten times.

 

There, trapped under a massive slab of concrete rubble near the robot's crushing treads, was Uraraka. The girl who had caught him. She was desperately clawing at the concrete, her leg pinned underneath it, her face pale with pain and terror.

 

The Zero Pointer raised a fist the size of a house, preparing to smash the street she was lying on into powder.

 

Izuku’s internal chronometer skipped a beat.

 

She's going to die.

 

Every warning alarm in his system went off simultaneously.

 

"WARNING. CORE TEMPERATURE AT 80%. SOTOBRO EFFECT INITIATION WILL RESULT IN CRITICAL THERMAL MELTDOWN."

 

I don't care, Izuku thought.

 

He didn't run. He knew he couldn't reach her in time by running. He planted his feet. He looked up at the monolithic machine.

 

And Izuku Midoriya forced his gears into overdrive.

 

CLICK-CLICK-CLICK-CLICK!

 

The ornate wind-up key on the top of his head spun with terrifying velocity. The screech of grinding, unlubricated metal echoed from his skull.

 

The glowing core in his chest shifted from emerald green to a blinding, searing white.

 

A shockwave of absolute temporal displacement erupted from his body. The dome of sepia-green energy instantly expanded, washing over the fleeing students, the collapsing buildings, Uraraka, and the colossal Zero Pointer.

 

The world froze.

 

The roar of destruction vanished, replaced by an eerie, dead silence. A piece of shattered glass hung suspended in mid-air right in front of Izuku’s face. The Zero Pointer's massive fist was frozen inches above Uraraka’s terrified, screaming face.

 

Everything was caught in the amber of stopped time.

 

Except Izuku.

 

TICK-TOCK-TICK-TOCK-TICK-TOCK!

 

His chest beat with the frantic, suicidal rhythm of a hummingbird's heart.

 

"Move," Izuku commanded himself.

 

He stepped forward. The sheer agony that ripped through his biomechanical body was indescribable. For every second he held the world still, the friction of fighting the universe's natural flow generated thousands of degrees of heat inside his chest.

 

His bronze armor began to glow cherry red. Steam violently vented from his shoulders, back, and knees, but because time was stopped, the steam didn't dissipate. It froze in the air behind him, leaving a solid, white trail of suspended vapor like a physical manifestation of his path.

 

Clank. Clank. Clank.

 

He reached Uraraka. He didn't waste time trying to shoot the concrete with a time ray; the energy output would detonate his core. Instead, he relied on his raw, mechanical weight.

 

He shoved his heavy bronze hands under the concrete slab. His servos whined in high-pitched agony. The metal of his forearms warped slightly under the heat and weight, but he lifted it. He threw the frozen slab aside.

 

He reached down and scooped Uraraka into his arms. She was locked in a state of terror, tears frozen perfectly on her cheeks.

 

"Warning! Meltdown imminent! Structural failure in 3... 2..."

 

Izuku turned and marched. Every step melted the rubber soles of his boots onto the pavement. He carried Uraraka out of the impact zone, lumbering fifty feet away, placing her gently on a safe patch of unbroken street.

 

He stood up. The heat was blinding him. His optical sensors were melting.

 

The key on his head slammed to a halt.

 

Click.

 

The sepia filter shattered. The universe snapped back into motion.

 

KA-BOOM!

 

The Zero Pointer's fist slammed into the street with the force of a meteor, utterly obliterating the spot where Uraraka had been lying a millisecond before. The shockwave sent dust and debris flying in every direction.

 

"Ahhhh!" Uraraka screamed, suddenly finding herself fifty feet away from the crushing blow, sitting safely on the pavement. She looked around wildly, gasping for air. "What?! How?!"

 

The other examinees turned around, absolutely baffled.

 

"Did she teleport?!"

"How did she dodge that?!"

 

But the blue-haired boy, Iida, wasn't looking at Uraraka. He was looking at the figure standing a few feet away from her.

 

Izuku Midoriya was not standing tall.

 

His bronze armor was glowing a violent, angry orange. A deafening, continuous scream of high-pressure steam was erupting from every seam in his body. The internal heat had completely melted his optical lenses, leaving hollow, smoking black pits where his glowing green eyes used to be.

 

"I... saved her," Izuku’s vocal synthesizer crackled out, the audio heavily distorted and pitched down like a dying cassette tape. "Time... is... out."

 

His heavy, burning knees buckled.

 

The Master of Time collapsed face-first onto the pavement, completely dead to the world, smoke billowing into the sky as the exam-ending buzzer echoed across the city.

 

 

 

"Out of the way! Move! Let me through!"

 

Recovery Girl hurried through the crowd of stunned teenagers. She took one look at the smoking, metallic heap on the ground and sighed in profound exasperation.

 

"Oh, for heaven's sake. Toshinori warned me about this one," the diminutive heroine muttered. She looked at Uraraka, who was frantically hovering over Izuku.

 

"Is he okay?! He just appeared out of nowhere! He's burning up!" Uraraka cried.

 

"Stand back, dear, a kiss won't fix warped bronze," Recovery Girl said. She pulled out a specialized radio. "Medical team! Bring the heavy coolant spray and the arc welders! We have a Class-4 thermal casualty!"

 

It took five rescue robots to lift Izuku onto a reinforced flatbed stretcher. As he was hauled away, steam still rising from his chassis, the examinees watched in a stunned, reverent silence.

 

He hadn't punched the robot. He hadn't fought the monster. But he had defied reality itself to save a life.

 

A week later, Izuku sat perfectly still on his reinforced stool in his bedroom. His body was a patchwork of repairs. Mei Hatsume, a manic student from the Support Course who Recovery Girl had contracted for mechanical assistance, had spent three days welding, polishing, and replacing Izuku’s melted internal fans. He had new optical lenses, which glowed with a sharper, brighter emerald hue.

 

His mother, Inko, walked into the room, tears already streaming down her face. She was holding a metallic disc.

 

"Izuku... it's here. From U.A."

 

She set the disc on his desk and backed away. Izuku reached out with a heavy bronze hand and pressed the button on the top.

 

A holographic projection flickered to life.

 

It was All Might, wearing a sharp yellow suit.

 

"Booyah! I am here as a projection!" All Might boomed.

 

Izuku’s gears ticked rapidly.

 

"Young Midoriya!" All Might's tone shifted to something incredibly warm and incredibly proud. "You performed admirably on the written test! However, your combat score was forty points. A respectable score, but on the borderline of passing!"

 

Izuku’s sensors dimmed.

 

"But!" All Might raised a finger. "The U.A. Entrance Exam is not just about destroying villains! How could an academy for heroes reject someone who risks their own life to save another?!"

 

The screen shifted, showing a clip of Uraraka in Present Mic's office.

 

“Excuse me! That boy, the big metal one... can I give him some of my points?! He saved me! He put himself in danger to get me out! Please!”

 

Izuku’s chest buzzed. She had tried to give him her points.

 

"A hero course that rejects a heroic spirit is no hero course at all!" All Might declared, his voice echoing in the small room. "Rescue points! A hidden metric used by the judges! Izuku Midoriya... for an act of selfless, logic-defying heroism..."

 

The scoreboard appeared on the screen.

 

Izuku Midoriya. Villain Points: 40. Rescue Points: 60. Total: 100 Points.

 

"First place," All Might smiled, pointing directly at the camera, looking straight into Izuku’s glowing green eyes. "Come, young Midoriya. This is your Hero Academia!"

 

The hologram vanished.

 

Izuku sat perfectly still. He didn't cheer. He didn't jump into the air. He couldn't.

 

Instead, he turned to his weeping mother. The key on his head gave a small, happy twitch.

 

"Mom," Izuku buzzed, his metallic voice laced with a warmth that completely defied his mechanical nature. "I'm going to be a hero."

 

 

The U.A. High School uniform was not designed for a boy made of four hundred pounds of solid, tempered bronze.

 

In his dimly lit bedroom, Izuku Midoriya stood perfectly still as his mother, Inko, meticulously adjusted his tie. The U.A. support company had done their best. The gray blazer was oversized, reinforced with Kevlar threading to prevent his heated joints from burning through the fabric. The shoulders were excessively broad, tailored to accommodate the massive, hydraulic ball-joints of his arms. The trousers were thick, hiding the heavy pistons in his calves, and his shoes were essentially custom-forged steel sabatons painted to look like sneakers.

 

"There," Inko said softly, her hands trembling slightly as she smoothed the lapels over his glowing green chest core. "You look incredibly handsome, Izuku."

 

"Thank you, Mom," Izuku replied. His vocal synthesizer buzzed with a gentle, resonant warmth. He raised a heavy, three-fingered hand and carefully patted her shoulder, hyper-aware of his own crushing strength.

 

He grabbed his oversized yellow backpack and stepped out the front door.

 

The commute to U.A. was an exercise in patience. Walking among the morning rush of civilians and students, Izuku was a rolling thunderclap. Every step he took resonated with a deep clank, followed by the rhythmic tick-tock of his internal chronometer. People gave him a wide berth. He didn't mind. For the first time in his life, the stares didn't feel like pity. He was walking toward the most prestigious hero academy in the world.

 

When he reached Class 1-A, he found a door that was obnoxiously large—nearly twenty feet tall.

 

Accessibility for Heteromorphic Quirks, Izuku calculated in his HUD. Logical.

 

He reached out and slid the massive door open.

 

The classroom was already buzzing with energy. Instantly, Izuku’s optical sensors locked onto two familiar figures. The tall, blue-haired boy from the exam orientation was chopping his arms aggressively at Katsuki Bakugo, who was sitting with his feet propped up on the desk.

 

"Remove your feet from that desk immediately!" the blue-haired boy demanded. "It is disrespectful to your classmates and the upperclassmen who sat there before you!"

 

"Huh? What middle school did you go to, you extra?" Bakugo sneered, small sparks popping from his palms. "I'll sit however I want."

 

Izuku stepped into the room. CLANK.

 

The heavy footfall instantly silenced the argument. The entire class turned to look at the doorway.

 

"Ah! It's the robot boy!" A cheerful voice broke the silence.

 

Izuku turned his heavy copper-and-bronze helm. Ochaco Uraraka was practically skipping toward him, her face beaming. "I didn't get to thank you properly after the exam! You were amazing! You totally melted, but you saved me!"

 

"It is... good to see you, Uraraka," Izuku buzzed.

 

The blue-haired boy marched over, his posture ramrod straight. "I am Tenya Iida! From Somei Private Academy! I must apologize for my behavior at the orientation. You realized the practical exam had a hidden rescue metric, didn't you? You acted with pure heroism while I was blinded by the scoring system. I concede! You are the superior student!"

 

"I... didn't know about the metric," Izuku said honestly, his internal cooling fans whirring slightly in embarrassment. "I just... my body moved on its own."

 

Bakugo, watching the exchange from his desk, scowled deeply. His crimson eyes bored into Izuku’s glowing green lenses. Deku. How the hell did a broken clock get into U.A.?

 

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

 

The voice came from the floor.

 

Izuku’s optical sensors panned down. Lying in a bright yellow sleeping bag outside the doorway was a man who looked like he hadn't slept in a decade. He unzipped the bag and stood up, revealing a scruffy face, messy black hair, and a capture scarf wrapped around his neck.

 

"It took you lot eight seconds to quiet down," the man drawled, stepping up to the teacher's podium. "Time is limited. You kids are not rational enough. I am Shota Aizawa. Your homeroom teacher."

 

The class gasped. This guy is a Pro Hero?! Izuku’s internal databases instantly recognized him. The Erasure Hero: Eraserhead. An underground hero. Extremely pragmatic.

 

Aizawa reached into his sleeping bag and pulled out a U.A. gym uniform. "Put these on and head out to the training field. We're doing a Quirk Apprehension Test."

 

 

 

The sun beat down on the dirt field behind the school. The entire class stood in their blue and white gym uniforms. Izuku’s uniform was a massive, custom-stitched tent of fabric that stretched over his blocky, mechanical frame. The wind-up key on his head protruded from the collar.

 

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

 

"What about the entrance ceremony? Or orientation?" Uraraka asked worriedly.

 

"If you're going to become heroes, you don't have time for leisurely events," Aizawa said coldly. "U.A.'s selling point is how unrestricted its traditions are. That applies to how the teachers run their classes, too."

 

Aizawa held up a smartphone displaying a list of fitness tests. "You kids have been doing these since junior high. But you were never allowed to use your Quirks. The country's education system is irrational; they try to equalize everyone. 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 tossed him a baseball.

 

Bakugo stepped into the pitching circle. He stretched his arms, a feral grin spreading across his face. He wound back, and as he threw, a massive explosion erupted from his palm. "DIE!"

 

The ball shot into the sky like a rocket, leaving a trail of black smoke.

 

Aizawa held up his phone, showing the screen to the class. 705.2 meters.

 

"Know your maximum limit first," Aizawa said, his eyes sweeping over the students. "That is the most rational way to form the foundation of a hero."

 

The class erupted in excitement. "Awesome!" "We can use our Quirks as much as we want!"

 

Aizawa's expression darkened. "Awesome, you say? You have three years to become heroes. Will you have that attitude the whole time? Fine. Whoever comes in last place in all eight tests will be judged to have no potential, and will be punished with expulsion."

 

A heavy, suffocating silence fell over the students.

 

Izuku’s internal chronometer skipped. Expulsion?

 

He looked down at his heavy, bronze body. He began to run rapid calculations in his HUD. Fifty-meter dash. Standing long jump. Sustained running. These are tests of agility and explosive physical movement. My body is designed for extreme durability and stationary chronal output. If I use my time acceleration to move my body faster, the friction will melt my leg joints. If I stop time for the Sotobro Effect, my core will overheat before I complete the tests.

 

Aizawa was watching Izuku closely. The underground hero had read Midoriya's file. A massive, Heteromorphic body containing an Emitter-class temporal core. He's a walking paradox. Insanely powerful, but trapped in a vessel that can't handle it. Let's see how he adapts.

 

The tests began.

 

Test 1: 50-Meter Dash.

 

Iida stepped up against a girl with a frog-like mutation, Tsuyu Asui. Iida’s engine legs propelled him across the finish line in 3.04 seconds.

 

Then, it was Izuku’s turn. He stepped to the starting line next to Bakugo.

 

"Ready... go!" the machine announced.

 

Bakugo blasted himself forward with continuous explosions, crossing the line in 4.13 seconds.

 

Izuku began to march. Clank. Clank. Clank. He engaged his servos to a brisk power-walk, but he was inherently constrained by his weight and center of gravity. His gears whirred loudly, venting a small puff of steam. He crossed the line.

 

14.28 seconds.

 

Bakugo sneered. "What a joke. You're slower than a turtle, Deku."

 

Test 2: Grip Strength.

 

Finally, a test of raw hardware. A massive, multi-armed student named Shoji scored an impressive 540 kilograms.

 

Izuku gripped the digital dynamometer with his three-fingered bronze claw. He didn't have muscles to strain. He simply increased the hydraulic pressure in his hand actuators. The gears in his forearm clicked, locking into place. The machine's numbers skyrocketed.

 

400... 600... 800... 999...

 

With a sharp CRACK, the metal handle of the dynamometer shattered in Izuku’s hand, crushed into a twisted knot of scrap.

 

"Oh," Izuku buzzed, holding up the broken machine. "I... broke it. I'm sorry."

 

Aizawa jotted a note on his clipboard. Immense physical strength. No biological fatigue.

 

Test 3: Standing Long Jump.

 

Bakugo cleared the sandbox entirely with a blast. A boy with a navel laser flew across it.

 

Izuku stood at the edge. He bent his heavy, piston-driven knees. He tried to leap.

 

He didn't fly. His four-hundred-pound frame barely left the ground before gravity aggressively reclaimed him. He landed with a massive THUD, his feet sinking two inches into the dirt, barely crossing the one-meter mark.

 

As the tests continued—repeated side-steps, seated toe-touches—Izuku’s score plummeted. He was simply not built for traditional athletics. He was dead last.

 

Finally, it was time for the ball throw.

 

Uraraka stepped into the circle. She tapped the ball with her fingers, negating its gravity, and tossed it into the air. It floated endlessly into the sky. Aizawa's device beeped: Infinity.

 

The class cheered. Izuku’s optical sensors whirred as he stepped forward, holding a standard baseball in his massive bronze claw.

 

I am in last place, Izuku calculated. If I simply throw the ball using my hydraulic strength, the aerodynamics of my arm swing and my limited joint rotation will only yield about eighty meters. I have to use my Quirk.

 

He stood in the circle, his core beginning to pulse. The wind-up key on his head twitched.

 

Suddenly, a profound wave of exhaustion washed over him. The glowing green light in his chest instantly died out. The ticking stopped. His entire body locked up, completely paralyzed.

 

Izuku panicked. What's happening?! Did my core fail?! Am I dead?!

 

He couldn't move his head, but his peripheral optical sensors caught a glimpse of Aizawa. The teacher's capture scarf was floating wildly around his neck, and his eyes were glowing red.

 

"I erased your Quirk," Aizawa said coldly, walking toward the frozen, bronze boy.

 

Aizawa kept his eyes locked on Izuku. "I saw your file. You stopped time at the entrance exam, saved a student, and instantly collapsed from critical thermal failure. You have zero control over your own power. You rely on a god-tier Quirk that actively destroys your vessel."

 

"I... can't... move," Izuku’s vocal synthesizer crackled weakly.

 

Aizawa blinked, his eyes returning to normal.

 

Instantly, the green light in Izuku’s chest flared back to life. The ticking resumed. Izuku gasped—a sharp intake of air through his ventilation grates—and stumbled forward, clutching his chest.

 

"Your Quirk is deeply tied to your life force," Aizawa noted, his expression grim. "When I erased your Emitter factor, your internal energy stopped. I practically gave you a mechanical heart attack. You're a walking liability, Midoriya. If you use your time stop here to cheat the throw, you'll overheat, pass out, and someone will have to carry you to the nurse. You cannot become a hero if you have to be saved after every single action."

 

Aizawa wrapped his scarf back around his neck. "You have one throw left. Do it normally, accept your limitations, and go home."

 

Izuku stared at the dirt. He's right. If I use the Sotobro Effect to stop time, the friction will melt my core. If I use accelerated time on the ball, it will turn to dust before it leaves my hand.

 

He looked at the ball in his hand. He looked at the vast, open field.

 

Wait.

 

Izuku’s processors kicked into overdrive. All Might taught me to wind the gears safely. I don't need to stop time for the entire world. I don't need to hold it for three seconds. I just need a micro-burst.

 

He stepped back into the circle.

 

He gripped the ball tightly. He didn't wind his arm back for a throw. He simply held the ball out in front of him.

 

Bakugo narrowed his eyes. What is that idiot doing? He's not even getting in a throwing stance.

 

Aizawa watched intently, his finger hovering near his eye, ready to erase the Quirk if the boy tried to kill himself again.

 

Izuku focused entirely on his core. He didn't command the energy to explode outward. He channeled it with surgical precision into the wind-up key on his head.

 

Click.

 

For exactly one-tenth of a second in real-time, the Sotobro Effect activated.

 

To the rest of the class, Izuku Midoriya flickered.

 

One millisecond, he was standing in the circle holding the ball. The very next millisecond, a massive shockwave of air exploded outward, blowing dust into the students' faces. A streak of white-hot steam hung in the air.

 

Izuku was still standing in the circle, but his arm was outstretched, empty. Steam was venting rapidly from his shoulder and back grates, but his bronze armor wasn't glowing red. He hadn't overheated.

 

"What... what just happened?" Iida gasped, adjusting his glasses.

 

"Did he throw it?! I didn't even see his arm move!" a boy with red, spiky hair named Kirishima yelled.

 

Aizawa looked at his smartphone. The machine was making a strange, high-pitched whirring noise, trying to calculate the data it had just received.

 

The screen blinked. Then, it displayed a symbol.

 

Error / Infinity.

 

Aizawa’s eyes widened slightly. He looked up at the bronze boy. "Midoriya... what did you just do?"

 

Izuku turned to face his teacher, his internal fans whirring loudly as he cooled his chassis.

 

"I didn't stop time for the world, Mr. Aizawa," Izuku buzzed smoothly. "I stopped time for my own body, localized it, and compressed it. In the span of a microsecond, I activated the time stop, walked to the absolute edge of the U.A. property line, placed the ball on the ground, and walked back to this circle before time resumed."

 

The class went dead silent.

 

"Because time was at absolute zero when the ball moved," Izuku explained, pointing a heavy finger at the smartphone in Aizawa's hand, "the machine calculated its velocity as infinite. Distance divided by zero time equals infinite speed."

 

Bakugo's jaw dropped. "He... he walked it out there? In zero seconds?!"

 

Aizawa stared at the screen, then at Izuku. The boy hadn't broken his body. He hadn't passed out. He had used his overwhelming, dangerous Quirk with terrifying, surgical precision. He had outsmarted the test, outsmarted the machine, and outsmarted Aizawa.

 

A terrifying grin spread across Aizawa's face.

 

"Rational," Aizawa said simply. "Very rational."

 

When the final scores were tallied, Izuku’s infinite score on the ball throw and his machine-breaking grip strength pulled him out of last place. He finished safely in the middle of the pack. The boy with the sticky balls, Mineta, came in last.

 

"By the way, I lied about the expulsion," Aizawa announced, flashing a creepy smile. "It was a rational deception to draw out your upper limits."

 

As the class collectively freaked out, Izuku felt his internal gears settle into a smooth, satisfied rhythm. He wasn't a liability. He was Deku, the ticking hero.

 

And his gears were just starting to turn.

 

 

 

The next day, Hero Basic Training began.

 

The door to the classroom burst open with dramatic flair. "I AM COMING THROUGH THE DOOR LIKE A NORMAL PERSON!"

 

All Might strode in, wearing his Silver Age costume. The class erupted into cheers, completely starstruck. Izuku’s optical sensors flared brightly. Seeing his mentor in his prime form, commanding the room, filled his mechanical heart with pride.

 

"Welcome to the most important class at U.A. High! Think of it as Heroing 101!" All Might boomed, striking a pose. "Today, we will be conducting Combat Training! And to go with that... these!"

 

He pointed to the wall, which slid open to reveal briefcases marked with seat numbers.

 

"Costumes made based on your Quirk registrations and requests you sent in before school started! Get suited up, and meet me at Ground Beta!"

 

In the locker room, the boys were eagerly putting on their new gear. Izuku stood in the corner, holding his massive briefcase. Because his body was his armor, his costume request to the support company had been highly specific. He didn't need kevlar or impact padding. He needed thermal management and style.

 

When Izuku stepped out into the sunlight of Ground Beta, the class stopped and stared.

 

He looked magnificent.

 

Over his polished, heavy bronze chassis, he wore a deep emerald-green, custom-tailored trench coat. The coat was sleeveless, allowing his massive, piston-driven arms full mobility. Thick, brass-colored exhaust pipes coiled around his shoulders and back, connecting to his internal cooling grates to safely funnel superheated steam away from his face. Around his neck, a white, dapper cravat provided a stark contrast to his metallic body.

 

But the most striking feature was his head. Over his smooth, copper helm, he wore a pair of dark, leather-strapped aviator goggles, giving him the appearance of a hardboiled, steampunk detective. The wind-up key on his head turned slowly, catching the sunlight.

 

"Whoa! Midoriya, you look like a walking tank!" Kirishima praised, hardening his arm in excitement.

 

"A very distinguished aesthetic!" Iida agreed, looking like a knight in his white armor.

 

Uraraka trotted over, wearing her pink, space-suit-like costume. "Deku! You look so cool! It really fits your whole time-machine vibe!"

 

"Thank you, Uraraka," Izuku buzzed softly, adjusting his coat. "Your costume... makes sense for your zero-gravity Quirk. It looks very functional."

 

"Deku?" Bakugo's voice sliced through the chatter.

 

Izuku turned. Bakugo was walking toward him, looking menacing in a black, tight-fitting suit with massive, grenade-shaped gauntlets on his forearms. His domino mask angled down in a furious glare.

 

"What kind of stupid name is Deku?" Bakugo snarled.

 

"It's the name you gave me, Kacchan," Izuku replied evenly. "You said it meant a useless, broken wind-up toy. But... Uraraka said it sounded like the Japanese word for 'You can do it.' So, I'm keeping it. Deku is my hero name."

 

Bakugo's eye twitched. The sheer audacity of the bronze freak adopting his insult as a badge of honor made his blood boil. "You think you're hot shit now, don't you, clockwork? Let's see how long that lasts."

 

All Might stood before the class, holding a script. "Now that everyone is ready, it's time for the Battle Trial! The situation is this: The villains have hidden a nuclear weapon somewhere in their hideout. The heroes must foil their plans! To win, the heroes must capture the villains or secure the weapon. The villains win if they protect the weapon or capture the heroes!"

 

All Might drew lots from a box to determine teams.

 

"Team A will be Izuku Midoriya and Ochaco Uraraka!"

 

Izuku and Uraraka shared a fist bump—careful not to crush her hand, Izuku merely tapped his bronze knuckles against hers.

 

"And they will be facing... Team D! Katsuki Bakugo and Tenya Iida! Team A will be the heroes, and Team D will be the villains!"

 

The air between Izuku and Bakugo instantly chilled.

 

Bakugo cracked his knuckles, a feral, terrifying grin stretching across his face. Perfect. I get to completely dismantle this walking pile of scrap.

 

Izuku remained perfectly still, but his internal core began to tick just a little bit faster.

 

 

 

Inside the multi-story building, Bakugo and Iida stood in a dark room on the top floor, guarding a massive papier-mâché bomb.

 

"Bakugo, we should formulate a strategy," Iida said, adjusting his helmet. "Midoriya's Quirk is extremely dangerous. He can manipulate time. We must ensure we do not let him get a clear line of sight, or he might age our armor to rust."

 

"Shut up, four-eyes," Bakugo growled, walking toward the door. "I don't give a damn about his time tricks. He's slow. He's a massive, four-hundred-pound target. I'm going to blitz him before his gears can even turn. You stay here and guard the toy."

 

Before Iida could protest, Bakugo stalked out of the room, hunting his prey.

 

Outside, Izuku and Uraraka stood before an open window on the ground floor.

 

"Okay, Deku, what's the plan?" Uraraka asked, bouncing on her toes. "If we run into Bakugo, he's definitely going to come straight for you."

 

"I know," Izuku said, his optical sensors scanning the dark hallway. "Kacchan is incredibly aggressive. He uses his explosions to propel himself at high speeds. I cannot outrun him. My top speed is barely a jog. If I try to use my localized time rays to rust his gauntlets, I risk hitting his skin and aging him, which would be lethal. I cannot use offensive time powers on a human."

 

"So... what do we do?" Uraraka gulped.

 

"You are going to find the weapon," Izuku commanded gently. "I am going to make sure Kacchan doesn't take a single step past me."

 

Izuku stepped into the building. Clank. Clank. Clank.

 

His footsteps echoed off the concrete walls, announcing his presence to the entire building. He wasn't trying to hide. He wanted Bakugo to find him.

 

As they rounded a corner on the second floor, a shadow moved at the far end of the corridor.

 

"Deku!" Bakugo's roar tore through the silence.

 

He didn't just run; he flew. Bakugo propelled himself down the hallway with massive, continuous explosions from his palms, moving at a speed that Izuku’s optical sensors could barely track.

 

"Uraraka, run!" Izuku buzzed.

 

Uraraka ducked into a side hallway just as Bakugo closed the distance.

 

Bakugo swung his right arm, aiming a point-blank, devastating explosion squarely at Izuku’s face. "DIE, YOU BROKEN TOY!"

 

BOOOOM!

 

The explosion ripped through the corridor. The concussive force shattered the windows and filled the air with thick, acrid black smoke. Flames licked the concrete walls.

 

In the observation room, the students gasped.

 

"Midoriya!" Kirishima yelled. "That was a direct hit to the head!"

 

"A sneak attack?! That's not manly at all!"

 

All Might leaned closer to the monitors, gripping the microphone tightly. Young Midoriya...

 

In the hallway, the smoke began to clear.

 

Bakugo stood with his arm outstretched, panting slightly, a savage grin on his face. That'll teach him.

 

But as the smoke parted, a heavy, metallic clicking sound filled the air.

 

Izuku Midoriya had not moved an inch. He hadn't been blown backward. He hadn't fallen over. He stood in the exact same spot, his heavy bronze boots planted firmly on the cracked tile. His aviator goggles were slightly charred, and the lapels of his trench coat were smoldering, but his bronze chassis didn't even have a dent.

 

Izuku raised his heavy, three-fingered hand and casually swatted the remaining smoke away from his glowing green eyes.

 

"You are fast, Kacchan," Izuku’s voice echoed, deep, metallic, and utterly devoid of fear. "Your explosive output is impressive. But... I weigh four hundred pounds. My armor is tempered bronze. You cannot move me with brute force."

 

Bakugo's eyes widened in absolute shock. He just tanked it? Like it was nothing?!

 

Rage, white-hot and blinding, consumed Bakugo. "DON'T LOOK DOWN ON ME!"

 

Bakugo leaped into the air, using explosions to maneuver behind Izuku in the blink of an eye. He aimed a double-handed blast directly at the exhaust pipes on Izuku’s back.

 

Izuku didn't turn around. He was too slow.

 

Instead, he engaged his Quirk.

 

Tick-tock-tick-tock!

 

The green light in his core flared. But he didn't stop time. And he didn't shoot a beam of aging energy.

 

He activated Retrocognitive Reversal.

 

A pale, cyan-blue aura erupted from Izuku’s back, washing over Bakugo just as the explosive boy unleashed his blast.

 

Instantly, Bakugo's momentum inverted. The fire from his palms sucked backward into his hands. His body was violently yanked backward through the air, completely defying physics, flying back down the hallway exactly the way he had come.

 

Bakugo landed on his feet at the far end of the corridor, his arms outstretched, in the exact position he had been in three seconds ago.

 

Bakugo blinked. The world spun. His stomach did a violent backflip, a wave of nauseating vertigo crashing into him.

 

"What... what the hell?!" Bakugo gagged, clutching his stomach. "What did you do?!"

 

Izuku slowly rotated his massive torso to face Bakugo. The ticking in his chest was steady, calm, and terrifyingly inevitable.

 

"I cannot outrun you, Kacchan," Izuku explained, raising a hand, the cyan light pooling in his palm. "But I don't have to. You are fighting in three dimensions. I am fighting in four."

 

Bakugo gritted his teeth, wiping saliva from his mouth. "You're dead!"

 

He charged again, zig-zagging off the walls, moving even faster, completely unpredictable. He closed the gap and threw a massive right hook aimed at Izuku’s core.

 

Izuku fired the cyan beam.

 

It hit Bakugo mid-swing.

 

VWOOM.

 

Bakugo was instantly rubber-banded backward in time. His body was violently dragged backward through the air, slamming his feet onto the floor at the end of the hallway once again.

 

The temporal whiplash was devastating. Bakugo dropped to one knee, clutching his head as a migraine, sharp and blinding, split his skull. His inner ear, responsible for his sense of balance, was completely shattered by the unnatural reversal of his physical timeline.

 

"Guh... agh!" Bakugo dry-heaved, his vision swimming.

 

"I am not rewinding your age, Kacchan," Izuku buzzed calmly, taking a slow, heavy step forward. Clank. "I am rewinding your physical position in space-time by exactly three seconds. Every time you attack, I will put you back where you started."

 

In the observation room, the class was staring in horrified awe.

 

"He's... he's playing with him," Kaminari, an electric-type student, whispered.

 

"He hasn't thrown a single punch," Todoroki, a boy with half-white, half-red hair, noted with narrow eyes. "He is using Bakugo's own speed against him, creating severe temporal motion sickness. It's a flawless defensive strategy."

 

Bakugo looked up at the lumbering, ticking machine walking toward him. For the first time in his life, Katsuki Bakugo felt completely and utterly helpless. He was the fastest, strongest fighter he knew. But you can't punch a clock.

 

"Stop looking at me like that!" Bakugo screamed, his pride shattering. He raised his massive right gauntlet, grabbing the pin. "If I can't touch you... I'LL JUST BLOW THE WHOLE HALLWAY TO HELL!"

 

"Young Bakugo, stop! Are you trying to kill him?!" All Might's voice blared over the intercom.

 

"He'll survive if he dodges!" Bakugo roared, pulling the pin.

 

A massive, apocalyptic beam of fire and concussive force erupted from the gauntlet, filling the entire hallway. The blast was easily ten times stronger than anything Bakugo had used before. It tore the walls apart, melting the concrete and vaporizing the tile.

 

The blast swallowed Izuku entirely.

 

When the fire died down, the hallway was a ruined, smoking crater. Bakugo stood at the end, panting heavily, his arm throbbing from the recoil.

 

He stared into the smoke. I got him. There's no way he tanked that.

 

"Warning. Core temperature 60%. External armor temperature critical."

 

The digital, synthesized voice echoed from the smoke.

 

Bakugo froze.

 

From the billowing black clouds, Izuku Midoriya emerged. His trench coat was completely incinerated, reduced to ash. His goggles were melted. His bronze armor was glowing a terrifying, furious orange, radiating waves of immense heat.

 

But he was still walking. Clank... hiss... Clank... hiss...

 

Izuku stepped out of the smoke, his glowing green core pulsing like a dying star. He raised a hand. The key on his head spun rapidly.

 

"Sotobro localized," Izuku buzzed.

 

He didn't fire a beam. He simply snapped his thick, bronze fingers.

 

The sound of the snap didn't echo. Instead, a wave of dense, heavy temporal energy washed over Bakugo.

 

Instantly, Bakugo felt his body turn into lead. His movements, his breathing, even his thoughts slowed to an absolute crawl. It felt like he was submerged in thick molasses. He tried to raise his arm, but it took five excruciating seconds just to move it an inch.

 

Izuku had applied a 90% temporal deceleration aura to him.

 

Izuku walked right past Bakugo. He didn't gloat. He didn't mock him. He simply lumbered past the frozen, struggling boy, his heavy footsteps shaking the floorboards.

 

"Deku... you... bastard..." Bakugo forced the words out, his voice dragging out into a deep, distorted groan of slowed time.

 

Izuku stopped, turning his head slightly.

 

"You are strong, Kacchan," Izuku said softly, his mechanical voice cutting perfectly through the slowed air. "But a hero doesn't just destroy things. A hero controls the situation. I control time."

 

Over the intercom, a buzzer blared.

 

"Team A has secured the weapon! The Hero Team wins!" All Might announced.

 

Upstairs, Uraraka had successfully floated herself over Iida and hugged the papier-mâché bomb while he was distracted by the explosion downstairs.

 

Izuku dropped his hand. The deceleration aura shattered.

 

Bakugo collapsed onto his hands and knees, finally succumbing to the temporal motion sickness. He vomited violently onto the concrete floor, his body shaking with exhaustion, rage, and a profound, terrifying new emotion: defeat.

 

Izuku stood there, venting steam into the ruined hallway, his gears ticking loudly in the silence.

 

He looked down at his heavy bronze hands, glowing red from the heat. He hadn't thrown a single punch. He hadn't destroyed a single wall. He had simply stood his ground, letting the world break itself against his armor.

 

I am a hero, Izuku thought, his core pulsing with a warm, steady light. I am Deku.
