What if Deku was trained by Shadow the Hedgehog for 5 years

 

The sting of ozone and burnt sugar hung thick in the humid afternoon air. It was a smell that nine-year-old Izuku Midoriya had come to associate with pain, humiliation, and the crushing reality of his own existence.

 

He lay flat on his back in the coarse dirt of the neighborhood playground, the rough sand biting into the scraped skin of his elbows and knees. Above him, the sky was a mocking, brilliant blue, completely indifferent to the brutal hierarchy of children that played out beneath it. His breath came in ragged, wet gasps, his chest heaving as he stared up at the canopy of oak leaves that did nothing to shield him from the glaring sun—or from the towering figure of Katsuki Bakugo.

 

"You really don't get it, do you, Deku?" Bakugo’s voice was a jagged sneer, laced with the intoxicating arrogance of a child who had been told from the moment his Quirk manifested that he was a god among men.

 

Izuku flinched, instinctively raising his trembling, bruise-mottled arms to shield his face. The green fabric of his favorite All Might t-shirt was singed black at the collar, still smoking faintly from the explosive blast that had thrown him to the ground seconds earlier.

 

Behind Bakugo stood two other boys—one with leathery, bat-like wings, and the other with unnaturally long, extending fingers. They were grinning, feeding off Bakugo’s dominance like scavengers waiting for scraps. Only moments ago, they had been cornering a much smaller boy, tormenting him for a minor slight. Izuku had stepped in, as his heart always commanded him to do. His legs had moved before his brain could process the danger. He had stood with his arms out, trembling like a leaf in a hurricane, telling Bakugo to stop.

 

The result was predictable. The boy he had tried to protect had run away the moment Bakugo's attention shifted, leaving Izuku to bear the full, explosive brunt of the blonde boy's wrath.

 

"You're Quirkless," Bakugo spat, stepping closer. The soles of his red sneakers crunched against the dirt, stopping just inches from Izuku’s side. He crouched down, his ash-blonde hair casting a jagged shadow over Izuku’s tear-streaked face. Small, warning pops of nitroglycerin sparked across the palms of his hands, illuminating his crimson eyes with miniature, violent suns. "You're a defunct piece of garbage. You can't even protect yourself, let alone anyone else. So stop pretending you can play hero, you worthless nerd."

 

"K-Kacchan..." Izuku choked out, his voice a pathetic, wavering squeak. Tears welled in his large, emerald eyes, spilling over his freckled cheeks and leaving muddy tracks as they mixed with the dirt. "I... I just wanted... it wasn't right..."

 

"Shut up!" Bakugo barked, slapping his sparking palm against the dirt right next to Izuku’s ear. The loud CRACK made the green-haired boy shriek, curling into a tight, defensive ball. "The only thing that isn't right is you breathing the same air as me! Know your place, Deku. You're nothing. You'll always be nothing."

 

With a final, disgusted scoff, Bakugo stood up. He turned his back on the crying boy, shoving his hands into his pockets. "Come on. Let's get out of here. He’s pathetic. The smell of his crying is giving me a headache."

 

"Yeah, whatever you say, Bakugo," the winged boy laughed, casting one last mocking glance at the crumpled form on the ground. "See ya around, Quirkless!"

 

The three bullies swaggered away, their cruel laughter echoing off the plastic slides and metal swing sets of the playground, slowly fading into the ambient noise of the distant city.

 

Left utterly alone, Izuku slowly uncurled his aching body. Every muscle screamed in protest. He pushed himself up onto his hands and knees, the dirt clinging to his sweat-drenched skin. The playground, usually a place of joy, felt like a sprawling, empty arena where he had just been fed to the lions.

 

He squeezed his eyes shut, but the tears refused to stop. They fell in heavy, salty drops, splattering against the dry earth. He's right, Izuku thought, the dark, insidious whisper of depression curling around his young heart. Kacchan is right. I’m Quirkless. I’m weak.

 

In a world where eighty percent of the population possessed some sort of superhuman ability, being part of the remaining twenty percent was a genetic death sentence. It wasn't just that he couldn't shoot fire or fly; it was that society viewed him as an evolutionary dead end. Fragile. Glass. A relic of a bygone era that belonged in a museum, not on the streets dreaming of being a hero.

 

The memory of the doctor's sterile office flashed in his mind. The cold, mechanical X-ray of his foot. The extra joint in his pinky toe. The doctor's deadpan, apathetic voice delivering the verdict: “You should probably give it up.” And then, the memory of his mother, Inko, clinging to him in the dark glow of the computer monitor, crying and apologizing over and over again, as if she had handed him a terminal illness instead of a genetic hand of cards.

 

"I just... I just want to be a hero..." Izuku sobbed aloud, burying his face in his hands. His small, thin shoulders shook violently. "Why was I born like this? Why am I so weak? It's not fair... it's not fair!"

 

He cried for what felt like hours. He cried until his throat was raw, until his eyes burned, and until his chest ached with a hollow, suffocating emptiness. He felt utterly, completely powerless. A victim of a universe that had decided he was a joke before he even took his first breath.

 

But the universe, as it turned out, was not done with Izuku Midoriya today.

 

 

 

The first sign that something was wrong was the sudden, oppressive silence.

 

The distant hum of traffic from the Musutafu streets abruptly ceased. The chirping of the cicadas in the nearby trees cut out as if someone had thrown a switch. Even the gentle afternoon breeze died completely, leaving the air suffocatingly stagnant.

 

Izuku sniffled, slowly lowering his hands from his face. He blinked through his tears, looking around. The atmosphere felt heavy, like the moment right before a massive thunderstorm, but the sky was clear.

 

Then, the hair on Izuku’s arms stood straight up. A strange, metallic taste flooded his mouth. Static electricity began to arc across the metal chains of the nearby swings, glowing with an eerie, sickly green luminescence.

 

W-What is that? Izuku thought, his crying momentarily halted by sheer confusion. Is it a villain? A hero fighting nearby?

 

Suddenly, the space roughly ten yards in front of him began to distort. It looked like the air above a hot asphalt road in the middle of summer, waving and warping violently. But the distortion grew, expanding into a swirling vortex of blinding, chaotic colors—emerald green, crimson red, and deep, void-like purple.

 

Izuku scrambled backward, a fresh wave of terror overriding his physical pain. He pushed himself against the wooden base of a playground structure, his eyes wide as saucers. The vortex spun faster and faster, emitting a high-pitched, screeching hum that made Izuku cover his ears. The grass beneath the portal ripped out of the ground, sucked into the swirling anomaly.

 

"CHAOS... CONTROL!"

 

A voice, deep, raspy, and echoing with unearthly power, roared from within the vortex.

 

With a deafening BOOM, the portal exploded outward. A shockwave of emerald energy tore through the playground, kicking up a massive cloud of dust, sand, and debris. Izuku squeezed his eyes shut and buried his face in his knees as dirt pelted against his back.

 

For a long moment, the only sound was the patter of falling debris settling back onto the earth.

 

Slowly, shakily, Izuku lifted his head. The vortex was gone. In its place, the air was still smoking, smelling strongly of ozone and something akin to burnt metal. In the center of the playground, where the sand was now pushed outward into a shallow crater, a silhouette crouched.

 

It wasn't a man. It wasn't a villain in any traditional sense.

 

As the dust began to clear, Izuku squinted, his breath catching in his throat.

 

Kneeling in the center of the crater was an anthropomorphic hedgehog. He stood roughly three feet tall, his fur pitch-black with striking, aggressive streaks of crimson red running up his quills, his arms, and his legs. He wore bizarre, frictionless-looking shoes that were white with red accents, metallic plating, and gold rings around the ankles. Matching gold rings rested on his wrists, securing thick white gloves.

 

The creature slowly stood up, brushing a patch of dust from his dark fur with a gloved hand. He cracked his neck, the sound sharp and distinct in the quiet air.

 

"Damn it," the hedgehog muttered. His voice was deep, gravelly, and carried a tone of supreme irritation. "That fake Emerald’s energy output was wildly unstable. Where the hell did that blast send me?"

 

Izuku sat paralyzed, his back pressed hard against the wood. Was it someone with a Mutant-type Quirk? He looked like a creature out of a cartoon, yet he carried an aura of intense, suffocating danger. The air around him seemed to warp slightly, radiating a latent, crackling energy.

 

The dark hedgehog reached to his chest, pulling out a dull, gray, diamond-shaped gemstone. He stared at it for a moment before crushing it in his fist with terrifying ease. The remains of the stone crumbled into ash.

 

"Useless," he scoffed.

 

Shadow the Hedgehog closed his eyes, extending his heightened senses outward. He needed to ascertain his location. He stretched his perception to feel for Chaos Energy, for the Master Emerald, for the familiar signatures of Sonic, Tails, or even Eggman’s robotic legions.

 

Nothing.

 

There was a complete and utter void of Chaos Energy. Instead, he felt strange, biological mutations surrounding him in the distance. Thousands of them. Millions of them. Organic beings emitting strange, localized energy fields—fire, ice, telekinesis, electricity. But no Chaos.

 

He was in another dimension. Again.

 

Shadow opened his eyes, a deep scowl settling over his muzzle. He crossed his arms over his chest, his crimson eyes narrowing. "Perfect. Stranded in an unknown dimension with no Chaos Emeralds. Just what I needed today."

 

He let out a slow breath, his mind already shifting into tactical mode. First step: secure intelligence. Second step: find a base of operations. Third step: locate a power source capable of replicating a spatial warp.

 

It was then that his ears twitched. He heard the ragged, terrified breathing.

 

Shadow snapped his head to the side. His piercing, crimson eyes locked instantly onto the trembling, green-haired boy huddled against the playground equipment.

 

Izuku felt like a rabbit caught in the gaze of a wolf. The creature’s eyes were intense—swimming with a depth of experience, violence, and sheer willpower that Izuku had only ever seen in the eyes of the top-ranking Pro Heroes on television.

 

Shadow uncrossed his arms and took a step forward.

 

Izuku scrambled backward, his hands slipping in the dirt. "P-Please! D-Don't hurt me! I don't have any money, and I don't have a strong Quirk to steal, I-I'm Quirkless, just please let me go!" he babbled, the words vomiting out of his mouth in a panicked rush.

 

Shadow stopped. He tilted his head slightly, his expression utterly unreadable.

 

Quirkless? The word meant nothing to him. But the state of the boy told an entire story. Shadow’s keen eyes analyzed the human child in a fraction of a second. He saw the dirt ground into the boy's knees. He saw the fresh, purple bruising forming on his jaw. He saw the singed, blackened fabric of his shirt, smelling the faint trace of nitroglycerin. And he saw the tears. So many tears.

 

For a singular, fleeting microsecond, a flash of blonde hair and blue eyes invaded Shadow’s mind.

 

Maria.

 

He remembered the sterile halls of the Space Colony ARK. He remembered how frail she had been. How helpless she was against the soldiers of G.U.N. She had been physically incapable of fighting back, a victim of her own failing biology. She had possessed a heart of gold, but a body made of glass.

 

Shadow’s fists clenched, the leather of his gloves groaning under the pressure. The memory of Maria always brought a pang of sorrow, but over the years, that sorrow had been refined into cold, hard steel.

 

He looked back at the boy. This child was not Maria.

 

Maria had been dying of NIDS, bedridden and physically broken. This boy? Shadow scanned his biology. The kid was scrawny, yes, but he was perfectly healthy. He had two arms, two legs, a functional musculoskeletal system, and no debilitating diseases. There was absolutely nothing physically stopping this child from defending himself.

 

Yet, here he was, cowering in the dirt, crying like the world owed him a favor.

 

The brief flicker of sympathy in Shadow’s chest evaporated, instantly replaced by a wave of cold, pragmatic disgust. He despised weakness that was chosen. He despised those who surrendered when they had the means to stand.

 

Shadow closed the distance between them in a blur of motion.

 

Izuku didn't even see him move. One second, the creature was ten feet away; the next, he was standing directly over Izuku, looking down at him with an expression of withering contempt.

 

"Stop crying," Shadow commanded. His voice wasn't loud, but it cut through the air like a serrated blade.

 

Izuku choked on a sob, his eyes widening. "I... I can't... I..."

 

"I said, stop crying," Shadow repeated, his tone dropping an octave, laced with a dangerous edge that made the hair on the back of Izuku's neck stand up. "Tears are a waste of water. They blind your vision and they tell your enemy that you've already given up. Are you giving up?"

 

"I-I don't even know who you are!" Izuku cried, pressing himself as far back as he could go. "A-Are you a villain?!"

 

"I am Shadow. Shadow the Hedgehog," he replied, his arms crossing over his chest once more. "As for what I am, that depends entirely on who is standing in my way. Right now, I am looking at a pathetic creature who prefers to roll in the dirt rather than fight back. Who did that to you?" Shadow nodded toward the blast mark on Izuku's shirt.

 

Izuku sniffled, wiping his nose with the back of his dirty arm. "K-Kacchan... Bakugo. H-He has an Explosion Quirk..."

 

"Quirk. You used that word twice. Define it."

 

Izuku blinked, momentarily pulled out of his terror by the sheer absurdity of the question. "You... you don't know what a Quirk is? Where are you from?"

 

Shadow’s crimson eyes narrowed sharply. "I ask the questions. Answer me, human."

 

"O-Okay! Okay!" Izuku stammered, raising his hands submissively. "A Quirk is a superpower! Eighty percent of the world has them. You can breathe fire, or fly, or have super strength. But... but I don't have one. I'm part of the twenty percent. I'm Quirkless." The last word tasted like ash in his mouth, triggering another fresh wave of tears. "Because I don't have a Quirk, I'm weak. Kacchan is strong. He can do whatever he wants to me, and I can't stop him."

 

Shadow remained silent for a long moment, processing this information. A society based entirely on genetic mutations. A caste system determined by innate biological power.

 

Shadow let out a harsh, mocking scoff. The sound was so filled with disdain that it made Izuku flinch.

 

"So, that's your excuse?" Shadow asked, his voice dripping with venom. "You lack a genetic anomaly, so you've decided to lie on your back and let the world walk all over you?"

 

"It's not an excuse!" Izuku yelled, a sudden, desperate spike of anger piercing through his fear. Nobody had ever talked to him like this. People either pitied him or bullied him. "You don't understand! Without a Quirk, you can't be a hero! You can't fight! I don't have any power!"

 

In a flash of movement, Shadow’s hand shot out. He grabbed Izuku by the collar of his ruined shirt and hauled him to his feet with terrifying, effortless strength. Izuku dangled in the air, his sneakers barely scraping the dirt, suddenly face-to-face with the black hedgehog.

 

"Listen to me, and listen well," Shadow growled, his crimson eyes burning into Izuku's emerald ones. "Power is not something you are born with. Power is a tool. A gun is a weapon, but without a disciplined hand to pull the trigger, it is a useless piece of metal."

 

Shadow dropped Izuku, who stumbled back and fell on his rear in the sand.

 

"You let genetics dictate your worth," Shadow continued, pacing slowly in front of the boy, his skates hovering slightly above the dirt. "You look at your lack of a 'Quirk' as a death sentence. I look at it as a blank slate. I was created to be the Ultimate Lifeform. I have powers you cannot possibly comprehend. But my power did not save the people I cared about. My power did not prevent me from being manipulated, beaten, and broken. Do you know what saved me?"

 

Izuku shook his head dumbly, completely captivated by the intense, raw gravity of the creature before him.

 

"My will," Shadow stated, stopping to look down at his own white-gloved hands. "My discipline. The refusal to stay down when the universe demanded I submit. You have two arms. You have two legs. You have a brain. And yet, you allow a child who throws fireworks from his hands to dictate your reality."

 

Shadow turned his back on Izuku, looking up at the sky. "It disgusts me."

 

The words hit Izuku harder than any explosion Bakugo had ever thrown. It disgusts me. It wasn't the bullying disgust of Katsuki, who hated Izuku for simply existing. It was the disappointment of a warrior looking at someone who refused to pick up a sword.

 

"I... I want to be strong," Izuku whispered, his voice cracking. He looked down at his own small, trembling, bruised hands. "I want to save people with a smile, like All Might. But I don't know how. I try, and I just get beaten down."

 

"Smiling is for fools who think the world is a game," Shadow replied without turning around. "The world is a battlefield. If you want to survive, you don't smile. You strike first, and you strike hardest."

 

Shadow glanced over his shoulder, his tactical mind clicking into place. He was in an unknown dimension. He needed a place to lie low, a place to gather information, and a place to formulate a plan to return to his own world. He could easily steal resources, but drawing attention from this world's authorities—these "Pro Heroes"—would be an unnecessary nuisance.

 

He needed a covert base. And he needed a guide.

 

He looked at the broken boy in the dirt.

 

An idea formed in Shadow's mind. A bold, perhaps arrogant idea, but one that suited his nature perfectly. This society worshipped innate power. They worshipped genetics. What better way to pass the time in this miserable dimension than to take their lowest denominator—a Quirkless, crying child—and forge him into a weapon that could shatter their entire worldview?

 

Shadow turned fully around, walking back until he was standing over Izuku once more.

 

"What is your name, boy?"

 

Izuku swallowed hard. "I-Izuku. Izuku Midoriya. B-But they call me Deku. It means useless."

 

"Deku," Shadow repeated, testing the syllables. He scoffed. "A fitting name for who you are right now. But that can change."

 

Shadow crossed his arms, staring down at Izuku with an uncompromising intensity.

 

"I find myself stranded in your world, Midoriya. I require shelter, food, and access to whatever information networks your society possesses. I cannot roam freely without drawing unwanted attention. Therefore, I propose a transaction."

 

Izuku blinked, rubbing his red, puffy eyes. "A transaction?"

 

"You will hide me," Shadow ordered. "You will provide me with a secure location—your home. You will not tell your parents. You will not tell authorities. In exchange, I will give you what you so desperately cry for."

 

Izuku’s breath hitched. "W-What?"

 

"I will train you," Shadow said, his voice dropping into a solemn, heavy vow. "I will break you down to your very foundation, and I will rebuild you. I will teach you how to fight, how to survive, and how to destroy those who think they are above you. I will turn you into the Ultimate Weapon, a force that needs no genetic 'Quirk' to command respect."

 

Izuku’s heart hammered against his ribs like a trapped bird.

 

Train him? Teach him to fight?

 

Nobody had ever offered to help him. Everyone, from his teachers to his own mother, had told him to give up, to temper his expectations, to learn to live at the bottom of the food chain. But this creature—this dark, intense being from nowhere—was offering him the keys to his dream.

 

But there was a catch.

 

"Will it... will it hurt?" Izuku asked, his voice a tiny whisper.

 

Shadow’s lips curled into a rare, sharp smirk. It was a terrifying expression. "More than you can possibly imagine. Every day will be agony. You will curse my name. You will beg me to stop. And I will not listen. But if you survive, you will never be afraid of that blonde brat—or anyone else—ever again."

 

Shadow uncrossed his arms and held out a white-gloved hand toward Izuku.

 

"So, Deku. Do you want to stay in the dirt and cry for the rest of your miserable life? Or do you want to stand up and make the world respect you?"

 

Izuku looked at the gloved hand.

 

He thought of Bakugo’s mocking laughter. He thought of the extra joint in his toe. He thought of the endless pity in his mother's eyes. He was so tired of crying. He was so, so tired of being weak.

 

The fear in Izuku's chest didn't vanish, but for the first time in his life, it was eclipsed by a burning, desperate spark of resolve. He reached out with a small, bruised, trembling hand, and grabbed Shadow’s glove.

 

Shadow gripped the boy's hand tightly, hauling him to his feet with a single, firm tug.

 

"Good," Shadow stated, releasing his grip and turning toward the exit of the playground. "We begin immediately. Take me to your base of operations."

 

Izuku wiped his eyes one last time. He looked down at his hands, then up at the dark figure waiting for him. He took a deep breath, steeling his nine-year-old heart, and took his first step forward.

 

"It's... it's this way. Follow me, Mr. Shadow."

 

"Just Shadow," the hedgehog corrected coldly, matching his pace to the boy's short strides as they walked out of the park and into the sprawling streets of Musutafu. "And do not expect any mercy from me, kid. By the time I am done with you, you will be a force of nature. Or you will be dead. There is no middle ground."

 

Izuku gulped, nodding firmly. "I understand."

 

As the strange duo walked down the sun-drenched sidewalk, drawing the occasional confused glance from passersby (who quickly looked away upon meeting Shadow's murderous glare), a shift began within the universe of Quirks and heroes.

 

Shadow the Hedgehog had made a vow. He looked at the scrawny, trembling child beside him, seeing past the bruises and the tears. He saw clay waiting to be fired in a kiln of absolute chaos. He would forge this boy into an unstoppable force. He would teach him the discipline of a soldier, the pragmatism of an assassin, and the unyielding pride of the Ultimate Lifeform.

 

Katsuki Bakugo, All Might, and the rest of this Quirk-obsessed society had no idea what was coming.

 

The era of the crying, helpless Deku was dead. The era of the Chaos Hero had begun.

 

 

 

Two Days Later: The Roof of the Midoriya Apartment Complex

 

The concrete roof of the four-story apartment building was blisteringly hot under the mid-July sun. The air shimmered with heat waves, and the faint smell of melting tar permeated the enclosed space. It was hidden from the street level, bordered by a high chain-link fence, making it the perfect, isolated training ground.

 

Izuku lay face down on the concrete, gasping for air as if he were drowning.

 

His muscles were not just sore; they felt as though they had been liquefied, drained out of him, and replaced with molten lead. Sweat poured off his forehead, stinging his eyes and pooling on the gray stone beneath him. He was wearing an old, oversized gray t-shirt and gym shorts, both utterly soaked through.

 

"Get up."

 

The command was flat, devoid of any sympathy or inflection.

 

Izuku groaned, pressing his trembling hands flat against the concrete. His triceps screamed in protest. He managed to push his upper body off the ground, but his elbows buckled instantly, sending him crashing back down onto his chin with a painful smack.

 

"I... I can't..." Izuku wheezed, tears of sheer physical exertion pricking the corners of his eyes. "My arms... they won't..."

 

A red and white shoe entered his field of vision, hovering an inch above the concrete.

 

"I did not ask for a medical assessment of your arms," Shadow’s voice drifted down, cold and sharp. "I told you to get up. Fifty more push-ups. Now."

 

"It's... it's been three hours..." Izuku sobbed, the familiar instinct to cry bubbling up to the surface. He couldn't help it. He was only nine. The things Shadow was making him do were impossible. "Please... just five minutes..."

 

Suddenly, Izuku felt a heavy pressure in the center of his back.

 

Shadow had stepped onto him. The hedgehog wasn't heavy by human standards, roughly thirty-five pounds, but to Izuku's exhausted, trembling frame, it felt like an anvil had been dropped on his spine.

 

"Tears," Shadow said, his tone dripping with the same disgust he had shown in the park. "Already resorting to tears. Tell me, Midoriya, when the explosion boy comes for you on Monday, will you ask him for a five-minute break? Will you cry and hope he feels pity for you?"

 

The memory of Bakugo’s sneering face flashed in Izuku’s mind. 'You're a defunct piece of garbage.'

 

"N-No..." Izuku grunted, squeezing his eyes shut.

 

"Then why are you crying now?" Shadow pressed his foot down slightly harder. "Your body is a machine. Your brain is the pilot. When the machine says it is broken, the pilot must force it to move anyway. That is what separates the weak from the strong. Push!"

 

With a roar of pure, unadulterated effort, Izuku squeezed his eyes shut and pushed.

 

His arms shook so violently it looked as though he were vibrating. The veins in his neck bulged. But slowly, agonizingly, his chest rose off the concrete. He lifted his own weight, plus the weight of the hedgehog standing on his back, until his arms were locked out.

 

"One," Shadow counted, his arms crossed casually over his chest as he balanced on the boy's back. "Down."

 

Izuku lowered himself, his muscles screaming.

 

"Up."

 

Izuku pushed back up, a ragged gasp tearing from his lips.

 

"Two," Shadow counted. "Down. Up."

 

For the next twenty minutes, Izuku experienced a level of hell he never knew existed. By the time Shadow finally stepped off his back at the count of fifty, Izuku collapsed entirely, rolling onto his back and staring blankly up at the sky. He couldn't move a single finger.

 

Shadow walked into his line of sight, blocking out the sun. The hedgehog's expression was unchanged—stoic, unreadable, and endlessly critical.

 

"Your physical foundation is pathetic," Shadow evaluated bluntly. "Your core strength is non-existent, and your fast-twitch muscle fibers are dormant. We will have to tear all of this down and start from zero."

 

Izuku could only nod weakly.

 

"However," Shadow continued, closing his eyes and turning his head slightly, a small, almost imperceptible smirk touching the corner of his muzzle. "You did not give up. That is a start."

 

Izuku felt a tiny, infinitesimal spark of pride warm his exhausted chest.

 

"Rest for exactly two minutes," Shadow ordered, pulling a small, ticking stopwatch from seemingly nowhere. He clicked it. "Then, we begin flexibility and balance training. I am going to teach you how to fall without breaking every bone in your fragile body. After that, we run."

 

"R-Run?" Izuku croaked. "How far?"

 

Shadow opened his eyes, locking his crimson gaze onto Izuku. "Until I tell you to stop."

 

 

 

The arrangement within the Midoriya household was a precarious tightrope walk of deception.

 

Inko Midoriya was a sweet, deeply anxious woman who worked long hours at an administrative job to support her son. She loved Izuku with every fiber of her being, and the guilt she felt over his Quirkless status ate at her daily.

 

Izuku hated lying to her. But Shadow had been very clear: if the mother found out, the training ended. Shadow had no intention of dealing with a hysterical human woman attempting to call animal control or local heroes.

 

So, Shadow lived in Izuku's closet.

 

It was a surprisingly functional arrangement. Izuku’s room was a shrine to All Might, plastered floor-to-ceiling in primary colors, action figures, and posters of the grinning Pro Hero. Shadow found the decor absolutely nauseating, referring to All Might as a "grinning idiot in spandex," but it provided ample cover.

 

During the day, while Inko was at work and Izuku was at school, Shadow had the apartment to himself. He used this time efficiently. He raided the refrigerator for whatever sustenance he required (he developed a rapid and intense affinity for coffee beans, which he ate whole, much to Izuku's horror). More importantly, he used Izuku's computer.

 

Shadow was a highly advanced being, fluent in hacking, decryption, and global surveillance thanks to his time working with G.U.N. The primitive internet of this alternate Earth was child's play for him.

 

Sitting in Izuku's desk chair, the glow of the monitor illuminating his dark fur and red stripes, Shadow devoured information. He hacked into the Hero Public Safety Commission databases. He researched the history of Quirks, the advent of the glowing baby in Qing Qing City, and the subsequent societal collapse and restructuring.

 

He studied the current ranking of Pro Heroes. He analyzed their Quirks, their fighting styles, and their arrest records.

 

Idiots, all of them, Shadow thought to himself one afternoon, scrolling through a video feed of the current Number One Hero, All Might, punching a giant villain into the stratosphere while laughing boisterously. They treat combat like a theatrical performance. They prioritize public relations over tactical efficiency. They announce their attacks. They wear bright colors. They are practically begging to be assassinated.

 

Shadow leaned back in the chair, crossing his arms.

 

This society was fundamentally flawed. It was built on a fragile pillar of reliance—reliance on heroes, reliance on Quirks, reliance on this smiling buffoon, All Might. If someone truly ruthless, someone who didn't play by their theatrical rules, were to systematically attack this foundation, the entire society would crumble in days.

 

Good thing I am not here to conquer them, Shadow mused, turning his attention away from the screen. I merely need to pass the time until my internal Chaos energy regenerates enough to forcefully breach the dimensional barrier.

 

He looked over at Izuku's bed, where the boy's meticulously organized notebooks sat on the nightstand.

 

Hero Analysis for the Future.

 

Shadow had read through them. The boy's handwriting was sloppy, and his fanboyish commentary was irritating, but beneath the childish adoration, there was a brilliant, analytical mind. Izuku was subconsciously deconstructing Quirks, finding their weaknesses, and conceptualizing countermeasures.

 

He just lacked the physical capacity and the killer instinct to execute them.

 

I will give him the capacity, Shadow thought. And I will beat the killer instinct into him.

 

The sound of the front door unlocking snapped Shadow from his thoughts.

 

"Izuku! I'm home!" Inko's voice called out from the entryway.

 

Shadow seamlessly powered down the monitor, leaped from the chair, and vanished into the depths of Izuku’s closet in a blur of black and red, pulling the door shut just a fraction of a second before Izuku's bedroom door swung open.

 

Izuku walked in, dropping his bright yellow backpack onto the floor with a heavy thud. He looked exhausted. His uniform was rumpled, and there was a fresh bandage on his cheek.

 

From the darkness of the closet, glowing red eyes observed him through the slats in the door.

 

Izuku didn't cry. He walked over to his mirror, inspecting the bandage. He traced the edge of it with a finger, his jaw clenching tightly. He turned, looking directly at the closet door.

 

"I didn't cry today, Shadow," Izuku whispered, his voice trembling slightly, but holding a nascent, fragile core of steel. "He pushed me into a desk, but I didn't cry."

 

The closet door clicked open, and Shadow stepped out into the room, his arms crossed. He looked at the bandage on the boy's face.

 

"Not crying is the bare minimum of emotional regulation, Midoriya," Shadow said bluntly. "You do not get a reward for acting like a functioning entity. Why did he push you?"

 

"Because... because I didn't move out of his way fast enough in the hallway," Izuku answered, looking down at his shoes.

 

"And why did you not move?"

 

"Because you told me yesterday that stepping aside for someone who disrespects me is an admission of inferiority."

 

Shadow’s ears twitched. A small, genuine smirk crossed his face. The kid was actually listening.

 

"Correct," Shadow said, stepping closer. "But letting him push you is still a failure. If he invades your physical space, you do not stand there like a training dummy. You redirect his momentum."

 

"But if I fight back, I'll get in trouble!" Izuku protested, his anxiety flaring up. "The teachers always side with Kacchan because his Quirk is so strong! They'll say I provoked him!"

 

"Let them say what they want," Shadow retorted, his voice turning icy. "Rules established by hypocrites are meant to be broken. If they punish you for defending yourself, then their system is corrupt, and their opinions hold no value. Do you want to be a good little student, or do you want to be strong?"

 

Izuku hesitated, the societal conditioning of nine years warring with the intoxicating ideology of the Ultimate Lifeform.

 

He looked at his All Might posters. All Might always followed the rules. All Might smiled and saved everyone.

 

But All Might wasn't here when Bakugo was burning his skin. All Might wasn't here when the teachers looked away. Shadow was here.

 

"I want to be strong," Izuku said, his voice dropping to a whisper.

 

"Then we escalate your training tonight," Shadow announced, turning toward the window. "We are done with basic conditioning. Tonight, I teach you how to strike. Put on your training gear and meet me on the roof in five minutes. And Midoriya?"

 

Izuku looked up.

 

"Take those ridiculous posters down," Shadow ordered, gesturing dismissively at the smiling faces of All Might covering the walls. "Idolizing someone else’s strength only highlights your own weakness. The only person you should rely on is yourself."

 

Izuku stared at the posters. He had loved All Might since he could walk. But looking at the smiling face now, he didn't feel the usual warmth. He just felt tired.

 

"Okay," Izuku said softly.

 

Shadow vanished in a blur of speed, heading out the window and up the side of the building.

 

Izuku stood alone in his room. He walked over to the largest poster above his bed—All Might in his Silver Age costume, laughing triumphantly. Izuku reached up, pinched the corner of the paper, and slowly, deliberately, ripped it off the wall.

 

It was the first of many things Izuku Midoriya would tear down in the years to come.

 

The rain came down in sheets, a torrential summer downpour that turned the abandoned construction site on the outskirts of Musutafu into a muddy, treacherous swamp. The sky was an unforgiving, bruised purple, completely blocking out the moon and stars. Thunder rolled in the distance, a low, guttural growl that reverberated in the chest.

 

In the center of the muddy expanse, a nine-year-old Izuku Midoriya was currently experiencing what he could only describe as a living hell.

 

"Again."

 

The word cut through the sound of the driving rain like a gunshot.

 

Izuku, completely soaked, his oversized gray t-shirt clinging to his shivering frame, gritted his teeth and launched himself forward. His sneakers slipped in the mud, but he forced his momentum upward, throwing a sloppy, desperate right hook.

 

A black and red blur sidestepped the punch with insulting ease. Before Izuku could even register the miss, a sharp, unyielding force struck the back of his knee, forcing his leg to buckle. As Izuku fell forward, a gloved hand grabbed the back of his neck and shoved him face-first into the cold, unforgiving mud.

 

Izuku lay there, sputtering, the foul taste of dirt and dirty rainwater filling his mouth. His muscles were vibrating with exhaustion. Every fiber of his being was screaming for rest. It was past midnight. They had been out here for five hours.

 

"Your footing is atrocious," Shadow the Hedgehog said, looking down at the boy with his arms crossed securely over his chest. The rain seemed to instinctively repel off his dark fur and quills. "You are relying on the friction of the ground to generate power. In a controlled environment, that is acceptable. On a battlefield, the environment will rarely be in your favor. You must generate power from your core, utilizing your own kinetic energy. Again."

 

Izuku pushed himself up onto his hands and knees. The mud sucked at his skin. His knuckles were raw and bleeding, the red washing away in the rain as quickly as it bloomed.

 

"Shadow..." Izuku wheezed, his voice cracking. "I... I can't feel my legs anymore. It's freezing. Please..."

 

Shadow stepped forward, his frictionless hover-skates making absolutely no sound in the mud. He knelt down so that his muzzle was mere inches from Izuku’s ear.

 

"Are you asking for my pity, Midoriya?" Shadow asked, his voice deathly quiet, yet carrying over the torrential rain. "Because if you are, I will leave right now. I will go back to the apartment, pack whatever supplies I need, and leave you here. And tomorrow, you can go back to school, look at the blonde boy who burns your skin, and accept your place at the bottom of the food chain. Is that what you want?"

 

Tears pricked the corners of Izuku’s eyes, instantly blending with the rain running down his face. His lower lip trembled. It was the natural, ingrained reaction of a child who had been coddled, bullied, and broken.

 

Cry, his brain told him. Cry, and maybe the pain will stop.

 

But then he looked into Shadow’s crimson eyes. There was no pity there. There was no malice, either. There was only an absolute, unyielding expectation. Shadow didn't view Izuku as a fragile, Quirkless glass doll. Shadow viewed him as a warrior who was simply refusing to pick up his sword.

 

Izuku bit his lower lip so hard he tasted copper. He squeezed his eyes shut, actively swallowing the sob that tried to claw its way up his throat.

 

I won't be weak, Izuku thought, a tiny, glowing ember of rage igniting in his chest. I won't be Deku.

 

"No," Izuku grunted. He planted his raw hands into the mud and forced his shaking legs to stand. He wiped the mud from his eyes, leaving a brown smear across his freckled face, and fell into the sloppy, unbalanced fighting stance Shadow had been trying to beat into him for the past month. "I don't want to stop. Teach me."

 

Shadow stood up, a microscopic hint of approval flashing in his eyes before returning to his standard, stoic scowl.

 

"Then fix your stance," the hedgehog commanded. "Your center of gravity is too high. You are top-heavy. Drop your hips. Tuck your chin. And stop telegraphing your strikes with your shoulders. If I can see you thinking about the punch, you are already too slow."

 

Izuku widened his stance, dropping his hips until his thighs burned.

 

"Now," Shadow instructed, uncrossing his arms and dropping into a loose, deceptive stance. "Come at me. And this time, do not try to hit my face. Try to hit the space behind my head."

 

With a guttural yell, Izuku charged again.

 

This was the beginning of the regimen. It was not a training montage from the comic books Izuku used to read. It was a brutal, agonizing, systematic deconstruction of his physical and mental limitations. Shadow the Hedgehog had been created aboard the Space Colony ARK to be the Ultimate Lifeform. His knowledge of combat, biomechanics, and survival had been programmed into his very DNA by the greatest scientific minds of his universe.

 

He applied this impossible standard to a scrawny, nine-year-old human.

 

 

 

Age 10: The Weights of Reality

 

The transition from nine to ten years old was a blur of agonizing soreness, constant hunger, and a radical shift in Izuku Midoriya's daily life.

 

To hide the physical toll the training was taking on him, Izuku had begged his mother to let him join an intense "mixed martial arts and gymnastics" club after school. Inko, relieved to see her son taking an interest in something other than obsessively muttering over hero fights, happily agreed, though she worried about the bruises he frequently came home with.

 

"It's just sparring, Mom," Izuku would lie smoothly, pulling his long-sleeved shirt down over the dark purple bruises that covered his forearms. "The instructor says I'm making great progress."

 

The truth was, the "instructor" was currently sitting in Izuku's closet, drinking a cup of black, unsweetened espresso he had brewed while Inko was out getting groceries, while simultaneously hacking into the U.A. High School public perimeter security cameras just to see if he could.

 

Izuku walked into his bedroom and locked the door behind him. He dropped his backpack by the desk and let out a long, heavy breath.

 

The closet door swung open, and Shadow stepped out. He analyzed the boy in a split second. Izuku was changing. The baby fat in his cheeks was gone, replaced by a sharp, slightly gaunt jawline. His posture was no longer hunched and submissive; he stood straighter, his shoulders squared.

 

"You are late," Shadow noted, placing his empty espresso cup on the desk. "You were dismissed from your academic institution twenty-four minutes ago. The walking distance is twelve minutes. Explain the discrepancy."

 

"Kacchan cornered me by the shoe lockers," Izuku said softly, his voice devoid of its usual anxious tremble.

 

Shadow’s ears twitched. "Did he strike you?"

 

"No," Izuku replied, walking over to his bed and sitting down. He stared at his own hands. "He cornered me and started yelling about how I was looking at him funny during class. He set off some explosions near my face. Burned a few hairs on my forehead."

 

"And what did you do?"

 

"Nothing," Izuku said, looking up at Shadow. There were no tears in his eyes. There was only a cold, clinical detachment. "I did exactly what you told me. I didn't flinch. I didn't apologize. I just looked at his collarbone, tracked his hands, and waited for him to actually throw a punch. But he didn't. When he realized I wasn't going to cry, he got confused. He called me a freak and walked away."

 

Shadow crossed his arms, leaning against the wall. "Good. Bullies are predators. They feed on the physiological response of their prey—fear, tears, submission. When you deny them that response, their internal script breaks. You become an anomaly. Predators avoid anomalies because they present an unknown risk."

 

Izuku nodded, absorbing the logic. It made perfect sense. It was so much more practical than All Might’s philosophy of 'smile and bear it.'

 

"However," Shadow continued, his eyes narrowing, "standing still while an enemy uses a Quirk in your proximity is a tactical error. If he had decided to blast your face, your reaction time would have been insufficient. You are still too slow."

 

Shadow walked over to Izuku's closet and pulled out a heavy duffel bag that Izuku had procured from a thrift store weeks ago. Shadow unzipped it and kicked it toward Izuku’s feet. It landed with a heavy, metallic clank.

 

Izuku looked down. Inside the bag were four heavy, dark metal bands lined with thick leather padding. Two for the wrists, two for the ankles.

 

"What are these?" Izuku asked, reaching down to pick one up. His arm immediately dropped under the unexpected weight. "Woah. These are incredibly heavy. What is this, solid iron?"

 

"Lead core with a steel casing," Shadow corrected. "I had to source the materials from a junkyard and weld them myself while your mother was asleep. They weigh approximately fifteen pounds each."

 

Izuku’s eyes widened. "Fifteen pounds? Each? That's sixty pounds total. Shadow, I barely weigh seventy-five pounds myself!"

 

"Your point?" Shadow asked coldly.

 

"If I put these on, I won't be able to run! I'll barely be able to walk without looking like a zombie."

 

Shadow stepped forward, his expression hardening into that terrifying, uncompromising scowl. "Your biology is weak, Midoriya. You lack a Quirk to enhance your strength or speed. Therefore, we must forcefully trigger muscular hypertrophy and neural adaptation. In my world, my inhibitor rings suppress my chaotic energy to keep my body from destroying itself. For you, these rings will act as a permanent, agonizing resistance. You will put them on. You will not take them off unless you are sleeping or bathing. You will wear them to school under your clothes."

 

"To school?" Izuku balked. "People will notice!"

 

"Let them notice," Shadow snapped. "If you complain about the weight, you are failing. The goal is not just to build muscle. The goal is to make this weight your new normal. So that when the day comes that you do take them off, your body will operate at a velocity that the human eye cannot track."

 

Izuku stared at the heavy metal bands. He thought of Bakugo’s explosions. He thought of the speed of the Pro Heroes on television. He thought of the Number One Hero, who laughed in the face of danger because he had the overwhelming power to back it up.

 

Izuku reached into the bag. He strapped the first heavy band around his left ankle, pulling the leather strap tight until it clicked. Then the right. Then his wrists.

 

He tried to stand up. His knees buckled instantly, his arms hanging down by his sides like dead weights. He felt like he was moving underwater. The gravity in the room seemed to have doubled.

 

"Pathetic," Shadow stated, walking over to the window and opening it. "Meet me at the abandoned train yard in twenty minutes. If you are late, you will do burpees until you vomit."

 

Shadow vanished out the window.

 

Izuku groaned, gritting his teeth as he forced his heavy legs to move. He took a step. His thigh muscles screamed. He took another.

 

Don't cry, Izuku thought, his expression morphing into a harsh, tight scowl. Don't complain. Just move.

 

It took him twenty-five minutes to reach the train yard. He spent the next hour doing burpees in the dirt, wearing the sixty pounds of lead, until his stomach emptied itself into the weeds. Shadow did not let him stop until he had completed a full hundred.

 

 

 

Age 11: The Breaking Point

 

The abandoned train yard, a graveyard of rusted boxcars and overgrown weeds on the edge of the city, had become Izuku’s second home.

 

He was eleven years old now. The physical transformation was subtle when he wore clothes, but beneath his oversized shirts, his body was becoming something entirely different. The boyish softness was gone, replaced by dense, tightly coiled muscle. His skin was marred with faint scars from missed dodges, scraped concrete, and the unrelenting friction of the heavy bands he wore every single day.

 

His mind had changed even more.

 

The stuttering, anxious boy who used to frantically scribble in his notebooks was gone. In his place was a quiet, observant adolescent. Izuku rarely spoke unless spoken to. At school, he sat in the back of the class, his arms permanently crossed over his chest, his emerald eyes coldly tracking everything around him. His classmates had stopped mocking him—not because they respected him, but because the aura he gave off was deeply unsettling. He didn't look like a victim anymore. He looked like a coiled spring.

 

Even Bakugo had subconsciously backed off. The blonde still threw insults and the occasional desk-kick, but he no longer tried to corner Izuku physically. The last time Bakugo had grabbed Izuku’s shoulder, Izuku hadn't panicked. He had simply turned his head, fixed Bakugo with a dead, emotionless stare, and said, "Remove your hand."

 

The sheer lack of fear in Izuku's voice had disturbed Bakugo so much that he had instinctively let go, covering his confusion with loud, blustering curses as he walked away.

 

But out here in the train yard, Izuku wasn't a stoic statue. Out here, he was a feral animal fighting for survival.

 

"You are too rigid!" Shadow shouted, darting across the roof of a rusted boxcar. He leaped off the edge, curling into a tight, spinning ball of black and red energy. He shot toward Izuku like a cannonball.

 

Izuku’s eyes widened. He crossed his heavily weighted arms in front of his face, bracing for impact.

 

The spinning attack slammed into Izuku’s guard. The sheer kinetic force of the blow shattered Izuku’s stance, sending him skidding backward through the dirt, his sneakers kicking up twin clouds of dust. He hit the side of a rusted train wheel with a painful thud, coughing as the breath was knocked from his lungs.

 

Shadow landed gracefully on his skates, arms crossed, staring down at his pupil.

 

"Blocking an attack of that magnitude is a fool's errand," Shadow lectured, his tone devoid of any coddling. "You absorbed the entire kinetic shock into your forearms. If I had been aiming to kill, both of your ulnas would be shattered right now. You are trying to fight like a brawler. You are not a brawler. You are a tactician with a severe weight disadvantage. Stop fighting the momentum and learn to ride it."

 

Izuku pushed himself off the wheel, wiping a trickle of sweat from his forehead. His breathing was heavy, his muscles burning from the constant strain of the sixty-pound weights.

 

"How?" Izuku demanded, his voice raspy. "You move faster than my eyes can track! If I try to dodge, I'm too slow with these weights! If I block, I take the damage!"

 

"Then don't be there when the attack lands!" Shadow snapped. "You are thinking linearly. Forward, backward, block, punch. That is how the idiots in your hero society fight. I am trying to teach you the art of Chaos. Chaos is unpredictable. Chaos is using the enemy's own velocity to orchestrate their destruction."

 

Shadow uncrossed his arms. "Attack me. Give it everything you have."

 

Izuku’s eyes narrowed, adopting the sharp, predatory scowl that he had unknowingly mirrored from his master. He didn't hesitate.

 

He lunged forward, using the heavy weights on his wrists to add devastating momentum to his swings. He threw a left jab, followed by a sweeping right hook aimed at Shadow’s ribs.

 

Shadow didn't block. As Izuku’s fist soared toward him, Shadow simply pivoted on his heel, shifting his body weight a fraction of an inch to the left. Izuku’s punch hit empty air. The heavy weight on Izuku’s wrist carried his arm forward, throwing his entire body off balance.

 

Before Izuku could recover, Shadow placed a single hand on Izuku’s extended arm and pushed lightly in the direction of the momentum.

 

Izuku went flying face-first into the dirt, entirely by the force of his own missed attack.

 

"Do you see?" Shadow asked calmly as Izuku spat out a mouthful of dust. "Your mass, plus your velocity, equals kinetic energy. When you missed, that energy had nowhere to go but forward. I didn't beat you. Physics beat you. Your quirkless state means you cannot afford to waste a single drop of energy."

 

Izuku pushed himself to his knees, his fists clenching in the dirt. Anger flared in his chest—not at Shadow, but at himself. He was eleven years old. He had been training for two years. He had endured more pain, more exhaustion, and more psychological breaking than any kid his age, yet he couldn't even touch a creature who barely came up to his waist.

 

"I'll show you physics," Izuku growled under his breath.

 

He stood up, his eyes locked onto Shadow. He didn't rush in this time. He took a deep breath, lowering his center of gravity. He let his arms hang loose by his sides. He visualized the momentum. He visualized the weights not as anchors, but as pendulums.

 

Shadow raised an eyebrow. Finally. He's thinking.

 

Izuku dashed forward. As he closed the distance, he threw a high roundhouse kick with his right leg.

 

Shadow smirked internally. Too slow. He leaned back to let the leg pass over his head.

 

But Izuku didn't commit to the kick. The moment his right leg missed, he didn't try to pull it back. Instead, he allowed the fifteen-pound weight on his right ankle to pull his body into a rapid, mid-air spin. He planted his left hand firmly into the dirt, using it as a pivot point, and whipped his left leg around in a vicious, sweeping sweep kick aimed directly at Shadow’s hover-skates.

 

It was Shadow’s signature technique—the low-sweeping breakdance kick—adapted for human biomechanics.

 

Shadow’s eyes widened a fraction of a millimeter in genuine surprise. He was forced to jump backward to avoid having his legs taken out from under him.

 

As Shadow landed, Izuku used the momentum of the sweep to spring off his hands, launching himself forward into a flying knee strike.

 

Shadow crossed his arms, catching the knee strike against his forearms. The impact pushed the hedgehog back half an inch, his skates leaving twin skid marks in the dirt.

 

Silence fell over the train yard.

 

Izuku landed gracefully on his feet, chest heaving, his arms instinctively crossing over his chest as he glared at his master. He had forced Shadow to block. He had moved Shadow backward.

 

Shadow slowly lowered his arms. He looked at his forearms, where a tiny smudge of dirt from Izuku’s knee was now transferred onto his pristine white gloves.

 

The hedgehog looked up at the boy. Izuku was standing tall, his jaw set, his eyes burning with a fierce, cold determination. The crybaby Deku was entirely dead. In his place stood a warrior forged in the crucible of agony.

 

A dark, genuine smirk spread across Shadow’s face.

 

"Not terrible," Shadow said, turning his back to brush the dirt off his gloves. "Your transition speed is still pathetic, and your landing was sloppy. But... your application of momentum was adequate."

 

From Shadow, that was the equivalent of a standing ovation.

 

"Now," Shadow said, turning back around, his eyes flashing dangerously. "Let me show you how to do it properly."

 

For the next three hours, Shadow beat Izuku into the dirt over and over again. But this time, Izuku didn't feel defeated. Every time he went down, he cataloged the movement. He analyzed the angle, the speed, the point of impact. He was no longer just surviving the regimen. He was learning how to hunt.

 

 

 

Age 11.5: The Anatomy of Destruction

 

The physical conditioning was only half of the Ultimate Lifeform’s regimen. The other half took place in Izuku's bedroom, under the dim light of a desk lamp, long after Inko had gone to sleep.

 

Izuku’s desk was covered in anatomical diagrams, medical textbooks he had checked out from the public library, and his own meticulously coded notebooks. Shadow stood on the desk, pointing to a diagram of the human nervous system with a pencil.

 

"Heroes in this society rely heavily on blunt force trauma," Shadow lectured, tapping the pencil against the skull of the diagram. "They use overwhelming Quirk power to batter their opponents into unconsciousness. This is inefficient, barbaric, and requires massive energy output. You do not have massive energy output. Therefore, you must become a surgeon."

 

Izuku leaned closer, his eyes scanning the diagram. "Precision striking."

 

"Exactly," Shadow confirmed. "Every biological organism, no matter how mutated their Quirk makes them, possesses structural weaknesses. Joints, arteries, nerve clusters, internal organs. You are not trying to punch through your enemy. You are trying to shut down their internal systems."

 

Shadow moved the pencil down to the neck of the diagram.

 

"The Vagus nerve," Shadow stated. "Located on the side of the neck. A sharp, focused strike here disrupts the autonomic nervous system, causing an immediate drop in blood pressure and heart rate. Unconsciousness follows in seconds. It requires less than ten pounds of pressure to execute."

 

"But if I strike too hard," Izuku muttered, rapidly jotting notes down in a heavily encrypted cipher Shadow had taught him, "I could crush the trachea or severe the carotid artery. It could be lethal."

 

"Yes," Shadow said coldly. "It could. Are you afraid of that?"

 

Izuku stopped writing. He looked up at Shadow. Two years ago, the thought of hurting someone, even a villain, would have sent him into a panic attack. Now, he simply processed the information as tactical data.

 

"No," Izuku said calmly. "A weapon is only lethal if the wielder chooses to be. If I have absolute control over my strikes, I control the outcome."

 

"Precisely," Shadow said, an edge of dark satisfaction in his voice. "Control. When you fight, you are entirely devoid of emotion. Anger makes you sloppy. Fear makes you hesitate. Compassion makes you dead. When you engage an enemy, you view them not as a person, but as a machine that needs to be dismantled. Where is the brachial plexus?"

 

Izuku immediately pointed his pencil to the armpit of the diagram. "Right here. A strike here causes temporary paralysis of the arm. Useful for disarming opponents with weapon or emitter-type Quirks located in the hands."

 

"And the celiac plexus?"

 

"The solar plexus," Izuku answered, pointing to the center of the abdomen, just below the sternum. "A strike here causes the diaphragm to spasm, resulting in severe respiratory distress. It knocks the wind out of them."

 

"Good," Shadow said, tossing the pencil onto the desk. "You are memorizing the map. But knowing the map and navigating the terrain in a fraction of a second are two different things."

 

Shadow hopped off the desk, landing silently on the bedroom floor. He crossed his arms, looking up at Izuku.

 

"Stand up."

 

Izuku stood, pushing the chair back. He fell into his stance—the loose, deceptive posture that allowed for maximum momentum generation.

 

"I am going to strike you," Shadow said calmly. "I will move at exactly twenty percent of my maximum speed. You will not block. You will parry, and you will target a pressure point on my arm. If you miss, I will hit you in the liver, and you will spend the next ten minutes wishing you were dead. Understood?"

 

Izuku swallowed hard. Shadow’s strikes, even holding back, were devastating. "Understood."

 

"Begin."

 

Shadow lunged. He was a blur of motion, his fist aiming squarely for Izuku’s midsection.

 

Izuku’s eyes, trained through months of agonizing visual tracking exercises, caught the subtle shift in Shadow’s shoulder a microsecond before the punch was thrown. Izuku didn't retreat. He stepped into the attack, pivoting his body sideways. He brought his left forearm up, striking the outside of Shadow’s incoming wrist to deflect the blow harmlessly past his stomach.

 

Simultaneously, Izuku’s right hand formed a rigid, spear-like chop. With a sharp exhale, he struck down hard on the radial nerve located on the top of Shadow’s forearm.

 

Smack.

 

Shadow stopped completely.

 

Izuku froze, his heart pounding in his chest. Had he done it right? Had he hit the exact spot?

 

Shadow slowly looked down at his arm. His right hand was trembling slightly, his fingers involuntarily twitching. The strike had successfully deadened the nerve, causing temporary numbness.

 

Shadow looked up at Izuku. The boy’s face was a mask of cold concentration, his arms pulling back into a defensive guard, his eyes tracking Shadow’s every micro-movement.

 

"Acceptable," Shadow grunted, flexing his fingers forcefully to shake off the numbness. The Chaos energy in his biology quickly repaired the minor nerve shock. "Your accuracy under pressure is improving. However, your strike lacked the necessary penetration depth to be permanently effective against a larger opponent."

 

"I held back," Izuku admitted, lowering his guard slightly. "I didn't want to break the bone."

 

Shadow’s eyes flared crimson. In an instant, the hedgehog vanished, reappearing directly behind Izuku. Before Izuku could react, a vicious, concentrated strike hit the center of his back, right between the shoulder blades.

 

The air violently expelled from Izuku’s lungs. His legs buckled, and he collapsed onto the bedroom floor, gasping like a beached fish. Pain radiated through his entire torso, a paralyzing, suffocating agony that made the edges of his vision go black.

 

Shadow stepped over him, looking down with utter disdain.

 

"Never hold back," Shadow growled, his voice a dark rumble. "Never assume your opponent is fragile enough to warrant your mercy. Hesitation on the battlefield is suicide. If you strike, you strike to break. You strike to destroy. Do you understand me?"

 

Izuku couldn't speak. He could only wheeze, clutching his chest as he rolled onto his side, fighting the primal urge to cry. He bit his tongue, squeezing his eyes shut.

 

Don't cry. Don't be weak. Adapt. Survive.

 

After agonizing minutes, the paralysis faded, and oxygen slowly returned to his lungs. Izuku pushed himself onto his knees, his face pale, sweat beading on his forehead. He looked up at Shadow, his emerald eyes hardened like cut glass.

 

"I understand," Izuku rasped, forcing himself to stand back up, his arms crossing over his chest defensively. "It won't happen again."

 

"See that it doesn't," Shadow replied coldly. "Now. Back to the diagram. You have thirty more pressure points to memorize before you are allowed to sleep."

 

 

 

Age 12: The Forging of the Chaos Scowl

 

Izuku Midoriya’s twelfth birthday came and went without fanfare. Inko had baked him a small cake, kissed his cheek, and told him she loved him. Izuku had smiled—a rare, genuine, but tightly controlled expression—thanked her, eaten exactly one slice to satisfy her, and then retreated to his room.

 

He didn't care about birthdays. He cared about progress.

 

He was standing shirtless in front of his bedroom mirror, examining his physique. He was not bulky. Shadow had explicitly forbidden exercises that generated excessive muscle mass, citing that it would ruin Izuku’s aerodynamic profile and slow down his rotational velocity. Instead, Izuku was carved from granite. His abdominal muscles were sharply defined, his obliques tightly coiled, and his back muscles rippled with dense, functional strength.

 

He moved his arms, observing the way the muscles engaged. He was a machine, finely tuned and rigorously tested.

 

The heavy, leather-bound lead weights were resting on his desk. He had just finished a three-hour parkour session across the rooftops of Musutafu, evading local police patrols and small-time Pro Heroes just for the endurance training.

 

He picked up a white t-shirt and pulled it over his head, hiding the physical proof of his torment. He turned to the mirror, crossing his arms over his chest. He lowered his chin slightly, letting his chaotic, messy green hair cast a shadow over his eyes. He let his facial muscles relax into a hard, uncompromising scowl.

 

It wasn't an act anymore. It wasn't a facade he put on to scare Bakugo. It was who he was.

 

He felt a profound sense of detachment from the world around him. When he walked down the street, he didn't see people; he saw potential threats, escape routes, and structural weaknesses in the buildings. When he watched the news, he didn't cheer for the heroes; he silently critiqued their terrible footwork and their over-reliance on flashy Quirks.

 

He was isolated, alone in a world that fundamentally misunderstood the nature of power.

 

The closet door opened, and Shadow stepped out. He was holding something.

 

Izuku turned around. "Are we heading back out?"

 

"No," Shadow said, walking over and placing four objects onto Izuku’s desk. "Your physical conditioning has reached the absolute limit of what those crude lead weights can provide. You have adapted to them. They are no longer providing sufficient resistance."

 

Izuku looked down at the desk.

 

Sitting there were four sleek, dark metallic rings. They were beautifully crafted, polished to a dull shine, with a latching mechanism that looked highly advanced. They heavily resembled the golden inhibitor rings that Shadow wore on his own wrists and ankles, though these were forged from a dark, gunmetal gray alloy.

 

"What are these?" Izuku asked, reaching out to touch one. The metal was cold.

 

"I utilized the machining equipment at a local industrial plant last night," Shadow explained, crossing his arms. "I designed them specifically for you. They are forged from an extremely dense tungsten-steel alloy, infused with a localized, electromagnetic locking mechanism. Each ring weighs precisely thirty pounds. That is one hundred and twenty pounds of permanent, dead weight."

 

Izuku stared at the rings. Double the weight he was currently wearing.

 

"Furthermore," Shadow continued, "the internal lining contains micro-sensors connected to a digital interface I have installed on your computer. It tracks your heart rate, muscular tension, and kinetic output. It will tell me exactly when you are slacking."

 

Izuku didn't complain. He didn't widen his eyes in shock. He simply picked up the first ring, unlatched the heavy clasp, and secured it around his left wrist.

 

The moment it clicked shut, Izuku’s arm dropped violently, his shoulder protesting at the sudden, extreme pull. It felt like an anchor had been chained to his bone.

 

Izuku gritted his teeth, a low grunt escaping his throat. He used his right hand to lift his left arm, forcing the muscles to engage, to fight the relentless gravity. He picked up the second ring and snapped it onto his right wrist.

 

He then sat down on his bed, strapping the final two rings around his ankles.

 

When he stood back up, the floorboards beneath his feet groaned slightly under the concentrated weight. Izuku closed his eyes, his breathing heavy, his entire body trembling as it struggled to support the extra one hundred and twenty pounds of mass.

 

"How does it feel?" Shadow asked, his voice low.

 

Izuku slowly opened his eyes. They were burning with a fierce, emerald fire. He lifted his arms, fighting through the agonizing burn, and forcefully crossed them over his chest. He locked his jaw, his expression settling into his signature, predatory scowl.

 

"It feels heavy," Izuku said, his voice entirely devoid of fear or complaint. "I will adapt."

 

Shadow smirked, a rare expression of genuine, unadulterated pride. The crying, helpless child he had found in the dirt three years ago was completely dead. In his place stood a prototype. A human vessel forged in the fires of Chaos.

 

"Yes, you will," Shadow said. "Tomorrow, you enter your final year of junior high. The environment will undoubtedly attempt to test you. You will not break. You will not submit. You will show them the discipline of the Ultimate Lifeform."

 

"I don't have time for their games anyway," Izuku replied, his voice mirroring the cold, raspy edge of his master. "Let them try."

 

Shadow nodded once, turning back toward the closet to return to his research.

 

Izuku Midoriya stood alone in the center of his room, his body vibrating with the effort of simply existing under the crushing weight of his new inhibitors. He looked at his reflection in the mirror one last time.

 

He was Quirkless. He was an anomaly. He was, by societal definitions, weak.

 

But as Izuku dropped his stance, throwing a painfully slow, heavily weighted punch at the air, he knew the truth. When the time came, when he finally released the latches on these rings, the world would have no choice but to bow.

 

The regimen was complete. The weapon was forged. Now, it just needed a target.

 

The alarm clock on Izuku Midoriya’s nightstand did not ring. It didn't buzz, and it didn't play a cheerful morning melody. It had been dismantled and rewired by a certain black hedgehog three years ago to emit a single, sharp, high-frequency pulse—a sound designed to instantly shock the human nervous system out of REM sleep and into combat readiness.

 

At exactly 4:00 AM, the pulse fired.

 

Izuku’s emerald eyes snapped open in the pitch darkness of his bedroom. There was no grogginess. There was no stretching, no yawning, and absolutely no desire to hit a snooze button. The transition from unconsciousness to total alertness took less than a fraction of a second.

 

He threw off the thin sheet and swung his legs over the edge of the bed. The moment his feet touched the wooden floorboards, a heavy, dull ache resonated through his joints.

 

Clink.

 

The faint, metallic sound of the dark tungsten-steel rings shifting against his skin filled the silent room. Thirty pounds on his left wrist. Thirty on his right. Thirty on each ankle. One hundred and twenty pounds of permanent, unforgiving gravity that sought to drag him down to the center of the earth every single second of his existence.

 

He had worn them constantly through the blistering heat of the summer break. He had worn them while running up the steep inclines of Musutafu’s surrounding mountains. He had worn them while Shadow ruthlessly battered him in the abandoned train yard.

 

Izuku stood up. His knees did not buckle. His shoulders did not droop. The agony was still there—a constant, burning fire in his musculature—but he had achieved what Shadow had demanded. He had made the agony his new baseline reality.

 

He walked over to the center of the room, assuming a wide horse stance. He crossed his arms over his chest, closing his eyes, and began his morning kata. He moved with agonizing slowness, forcing his muscles to fight the tungsten rings through every millimeter of the motion. A slow, heavy punch. A guarded block. A sweeping kick.

 

From the shadows of the closet, a pair of glowing crimson eyes watched him.

 

"Your left hip is trailing by a centimeter," Shadow’s raspy voice cut through the darkness, devoid of morning pleasantries. "You are compensating for the weight on your ankle by shifting your center of balance to the right. Correct it, or I will break your right leg so you are forced to balance evenly."

 

Izuku didn't flinch at the threat. He merely shifted his hips, feeling the burn intensify in his left thigh as he squared his posture.

 

"Corrected," Izuku replied, his voice deep, calm, and slightly raspy from lack of use.

 

"Hmph," Shadow grunted, stepping out of the closet. The hedgehog walked over to Izuku's desk and picked up a small, heavily encrypted digital tablet he had fabricated. "Today marks the beginning of your final academic year at that glorified daycare you call a junior high school."

 

"Aldera," Izuku provided calmly, smoothly transitioning into a slow, weighted roundhouse kick.

 

"Irrelevant," Shadow dismissed, crossing his arms. "The institution is a breeding ground for arrogance and complacency. They will expect the boy who left them in the spring. They will expect the stuttering, crying weakling. You will not give them that."

 

Izuku lowered his leg, bringing his feet together and exhaling a slow, measured breath. He opened his eyes, staring blankly at the wall. "I have no intention of regressing, Shadow. I don't care what they expect. They are irrelevant to my objective."

 

Shadow’s lips quirked upward into a sharp, approving smirk. "Good. Remember your parameters. You are wearing the rings. You are operating at a severe velocity handicap. If you are forced to engage, you do not brawl. You dismantle. Do not waste energy on flashy movements. Shut down the threat, assert your dominance, and walk away."

 

"Understood."

 

"Then prepare yourself," Shadow commanded, turning his back and walking toward the window. "I have reconnaissance to conduct regarding the Hero Public Safety Commission's patrol routes today. I will review your performance tonight."

 

With a flash of chaotic red and green energy, Shadow vanished into the early morning air.

 

Izuku stood alone. He walked into his attached bathroom, turning the shower knob to the coldest setting. He stepped under the freezing spray, letting the ice-cold water shock his muscles, reducing the microscopic inflammation caused by the rings. He didn't shiver. He just stared at the drain, his mind a quiet, organized vault of tactical data and kinetic equations.

 

Forty minutes later, Izuku walked into the kitchen. He was dressed in the standard black gakuran uniform of Aldera Junior High. However, Inko Midoriya had been forced to take the uniform to a tailor twice over the summer. Izuku’s shoulders had broadened significantly, his chest thickening with dense, coiled muscle that the standard issue fabric simply couldn't contain without tearing. The uniform was now custom-fitted, hiding the bulky tungsten rings beneath the lengthened sleeves and the widened cuffs of his trousers.

 

Inko was at the stove, humming softly as she flipped a piece of grilled mackerel. She turned, offering her son a warm, albeit slightly nervous, smile.

 

"Good morning, Izuku! Did you sleep well?"

 

Izuku pulled out a chair and sat at the small dining table. He kept his posture perfectly straight. "I slept adequately, Mother. Thank you."

 

Inko’s smile faltered slightly, a flash of sorrow passing through her eyes. She missed the days when her son would bounce into the kitchen, excitedly babbling about the newest hero debut or analyzing a fight he had seen on the news. Over the past three years, her little boy had slowly faded away, replaced by this intense, quiet, almost intimidating young man.

 

She placed the plate of rice, fish, and miso soup in front of him. "Are you... are you excited for your first day as a third-year? It's an important year, Izuku. You'll be applying to high schools soon."

 

"It is a necessary stepping stone," Izuku replied evenly, picking up his chopsticks. He ate with mechanical efficiency, chew by chew, focused solely on optimal caloric intake. "Nothing more."

 

"Right," Inko murmured, wringing her hands on her apron. "And... and if Katsuki gives you any trouble this year... you'll tell the teachers, right? Or you'll tell me?"

 

Izuku paused. He looked up at his mother. He loved her. He truly did. But she fundamentally did not understand the world they lived in. She believed the rules protected people. Izuku knew that rules only protected the strong from accountability.

 

"Bakugo will not be an issue," Izuku said, his voice flat, resolute, and carrying an absolute certainty that made Inko shiver. "Do not worry about me, Mother."

 

He finished his meal, washed his dishes with precise, practiced movements, and slung his yellow backpack over his shoulder.

 

"I am departing. Have a productive day at work."

 

Before Inko could say another word, the front door clicked shut. She stood in the quiet kitchen, looking at the empty chair, wondering when her fragile little boy had turned into a soldier.

 

 

 

The walk to Aldera Junior High took exactly twenty-four minutes at Izuku’s current, heavily weighted pace.

 

The morning air of Musutafu was crisp, filled with the bustling sounds of commuters, honking cars, and the ever-present, blaring news broadcasts displayed on the sides of skyscrapers.

 

As Izuku walked, his hands casually stuffed into his pockets, he observed his environment with the cold, calculating gaze of a predator mapping its territory. His emerald eyes darted from rooftop to rooftop, cataloging structural weak points, identifying optimal escape routes, and calculating the wind velocity based on the sway of the traffic lights.

 

A loud explosion echoed down the block, followed by the sound of shattering glass and screaming pedestrians.

 

Izuku stopped at the crosswalk. Half a block down, a villain with a minor gigantification and rock-manipulation Quirk was tearing through the front of a jewelry store. Debris flew into the street. Panic ensued.

 

Two seconds later, a Pro Hero swung into the fray—Kamui Woods.

 

Izuku watched with deadpan apathy. Three years ago, he would have been pushing his way to the front of the crowd, notebook in hand, vibrating with excitement. Now, he just crossed his arms, the heavy tungsten rings clicking softly beneath his sleeves, and analyzed the tactical disaster unfolding before him.

 

The villain is top-heavy, Izuku noted internally, watching the massive rock creature swing wildly at Kamui Woods. His center of gravity is entirely misaligned. His knees are buckling under the added weight of his own Quirk. Kamui Woods is attempting a frontal assault using his arbor manipulation to bind the arms. Idiotic. He's fighting the enemy's strength.

 

Kamui Woods shouted a dramatic attack name—something about a "Pre-emptive Binding"—and shot a barrage of wooden branches at the villain. The rock villain merely laughed, flexing his massive arms and shattering the wood into splinters. Kamui Woods was thrown backward, crashing into a lamppost.

 

The villain's popliteal artery behind the knee is completely exposed, Izuku continued his silent, scathing critique. If Kamui Woods possessed any actual martial arts training, he would slide under the attack radius, deliver a localized, high-impact strike to the back of the knee, collapse the villain's structural integrity, and follow up with a concussive blow to the vagus nerve in the neck. The fight would be over in 3.4 seconds. Instead, he is playing to the cameras.

 

The crosswalk light turned green, emitting a cheerful, chirping sound.

 

Izuku didn't wait to see the end of the fight. He turned his back on the spectacle, adjusting the straps of his backpack, and continued his walk. He didn't have time to watch amateurs play dress-up.

 

When the imposing, iron-wrought gates of Aldera Junior High came into view, the atmosphere immediately shifted.

 

The courtyard was packed with returning students. Groups of teenagers huddled together, laughing, comparing their summer vacations, and gossiping about the upcoming year. The air was thick with the arrogant, chaotic energy of adolescents who believed they were the center of the universe.

 

Izuku stepped through the gates.

 

He didn't slouch. He didn't try to make himself small. He stood at his full height—which, thanks to Shadow’s rigorous nutritional planning and physical conditioning, was noticeably taller than the majority of his peers. His posture was perfectly straight, his shoulders broad and imposing beneath the black fabric of his uniform. His head was tilted slightly downward, his messy green hair casting a dark shadow over his half-closed, emerald eyes. His arms were crossed over his chest, his face set in a terrifyingly cold, emotionless scowl.

 

As he walked up the main pathway, the ambient noise in his immediate vicinity began to die down.

 

Students who had been laughing and shoving each other instinctively paused, stepping out of his path. They looked at the approaching boy, confusion morphing into unease.

 

"Who is that?" a second-year girl whispered to her friend, clutching her books to her chest. "Is he a transfer?"

 

"No way, look at his hair. Is that... is that Midoriya?"

 

"Deku? No, that can't be him. Deku is tiny and he always stutters. That guy looks like he could punch a hole through a wall."

 

Izuku heard the whispers. He ignored them. They were white noise. He kept his steady, heavily weighted pace, his eyes locked straight ahead. He projected an aura of absolute, suffocating pressure—a psychological technique Shadow had drilled into him. ‘Walk as if the earth is privileged to bear your weight,’ Shadow had instructed. ‘Project your intent. Make them feel their own insignificance before you even raise a fist.’

 

As Izuku passed a group of third-year boys, one of them—a kid with a minor speed Quirk who used to trip Izuku in the hallways—stepped forward, trying to show off for his friends.

 

"Hey, Deku!" the boy jeered, puffing out his chest. "Did you hit a growth spurt or something? Still Quirkless and useless, though, right?"

 

Izuku didn't stop walking. He didn't turn his head. He didn't uncross his arms. As he passed the boy, Izuku merely shifted his emerald eyes to the side, locking his gaze with the bully for a fraction of a second.

 

Izuku’s eyes were dead. There was no anger, no annoyance, no fear. There was only the cold, clinical look of an apex predator looking at a very small, very loud insect.

 

The speed-Quirk boy froze instantly. The mocking smile melted off his face, replaced by a sudden, irrational spike of primal terror. All the bravado vanished from his body, and he involuntarily took a step backward, his breath hitching in his throat.

 

Izuku looked forward again, continuing his walk into the school building without uttering a single syllable.

 

The boys in the courtyard watched him go in stunned silence.

 

"Dude," one of the friends whispered, shoving the speed-Quirk boy. "Why didn't you do anything? He completely ignored you."

 

"I... I don't know," the boy stammered, rubbing his arms. The hair on the back of his neck was standing straight up. "I just... I felt like if I moved, he was going to kill me."

 

 

 

Class 3-A was exactly the same as it had been the year prior, save for the seating arrangements. Izuku found his assigned desk near the back by the window. It was tactically optimal. He had a clear view of every student in the room, the teacher’s desk, both exits, and the window allowed for an immediate emergency egress if necessary.

 

He sat down, his heavy rings clunking softly against the wood of the chair. He crossed his arms, leaned back, and closed his eyes, centering his breathing.

 

The classroom slowly filled up. When the bell rang, the homeroom teacher walked in, holding a large stack of papers.

 

"Alright, settle down, everyone!" the teacher called out, slamming the papers onto his podium. The chatter died down. "Since you are all third-years now, it's time to start thinking seriously about your futures. I'm going to hand out these printouts for your desired career paths."

 

The teacher paused, a patronizing smile crossing his face. He grabbed the entire stack of papers and tossed them into the air.

 

"But who am I kidding? You all want to be heroes, right?!"

 

The classroom erupted. Quirks flashed across the room. A boy stretched his neck like a snake. A girl shot water from her fingertips. Another boy generated minor electrical sparks. It was a chaotic, disorganized display of genetic superiority.

 

Izuku did not move. He kept his arms crossed, his eyes half-closed, staring blankly at the blackboard. His lack of reaction was a stark, jarring contrast to the cheering class.

 

"Yes, yes, you all have wonderful Quirks," the teacher chuckled, waving his hands to calm them down. "But remember, using your Quirks in school is strictly against the rules."

 

"Hey, Teach! Don't lump me in with these background extras!"

 

A loud, arrogant voice cut through the noise, accompanied by the distinct sound of leather boots propping up onto a desk.

 

Katsuki Bakugo leaned back in his chair in the front row, a cocky, feral grin plastered across his face. Small, warning pops of nitroglycerin sparked across his palms. "They'll be lucky to end up as sidekicks to some busted D-lister. I'm the real deal. I'm going straight to the top."

 

The class immediately turned on him, shouting indignantly.

 

"You think you're better than us, Bakugo?!"

 

"Shut up, you extras!" Bakugo roared back, a larger explosion popping in his hand. "I aced all the mock tests! I'm the only one here with the power, the grades, and the pedigree to get into U.A. High School! I'm going to surpass All Might and become the Number One Hero, and all of you are just stepping stones!"

 

The teacher looked down at a clipboard on his podium, pushing his glasses up his nose.

 

"Ah, yes. You're aiming for U.A., Bakugo. Your test scores certainly reflect that." The teacher scanned the list further, his eyebrows raising in mild surprise. "Oh. It seems Midoriya is also applying for U.A."

 

The classroom went completely, utterly silent.

 

All eyes slowly turned to the back of the room, fixing on the green-haired boy sitting by the window.

 

For the past two years, whenever this topic was brought up, this was the part where the class would burst into uproarious laughter. This was the part where Izuku would shrink into his seat, stammering defensively, waving his hands, and trying to explain that they accepted Quirkless students now, that he just wanted to try.

 

Bakugo slowly turned his head, his crimson eyes locking onto Izuku. The blonde's face contorted into a mask of pure, unadulterated fury at the sheer audacity of the Quirkless nerd daring to challenge his spotlight.

 

But the laughter never came.

 

Because Izuku didn't shrink. He didn't stammer. He didn't even look at the class.

 

Izuku was resting his chin on his knuckles, looking out the window. His expression was completely blank, devoid of fear, embarrassment, or even interest. He looked utterly bored.

 

The silence stretched on, becoming thick and profoundly uncomfortable. The students waited for the punchline, they waited for the victim to play his part, but the victim was gone. The boy sitting in that chair exuded a quiet, dark menace that made the air in the room feel heavy.

 

Bakugo’s eye twitched. A vein throbbed on his forehead. The lack of fear from Deku—the lack of acknowledgement—infuriated Bakugo more than any insult ever could. Deku was treating him like he didn't even exist.

 

"Deku..." Bakugo growled, his palms smoking. He started to stand up from his desk.

 

"A-Alright, moving on!" the teacher stammered quickly, sensing the incredibly dangerous shift in the atmosphere and desperately wanting to avoid a brawl on the first day. "Let's pass out the syllabuses for the semester!"

 

Bakugo slowly sat back down, his eyes burning holes into the side of Izuku's head. You think you've changed, you Quirkless piece of garbage? Bakugo thought, his hands clenching into tight fists. I'll remind you exactly where you belong.

 

Izuku felt the murderous glare. He slowly closed his eyes, a tiny, almost imperceptible scoff escaping his lips.

 

Predictable.

 

 

 

The confrontation was inevitable. Shadow had warned him it would happen. It was simple biology; an apex predator whose dominance was suddenly questioned by the lowest rung of the food chain had to reassert control, or risk losing their status entirely.

 

It happened immediately after the final bell rang.

 

Izuku packed his notebooks into his yellow bag with slow, deliberate precision. He slung the bag over his shoulder, stood up, and walked out of the classroom.

 

The hallway was crowded with students heading to their lockers or club activities. Izuku walked with his hands in his pockets, his posture perfect, his face a mask of absolute indifference.

 

"Hey. Deku."

 

Izuku stopped. He didn't turn around. He simply stood in the middle of the hallway.

 

The sea of students around them immediately parted, pressing themselves against the lockers to clear a wide circle. Nobody wanted to be caught in the crossfire.

 

Bakugo stepped into the center of the hallway, flanked by two of his lackeys—the boy with extending fingers, and the boy with bat wings. Bakugo’s face was twisted into a grotesque sneer, his shoulders hunched aggressively.

 

"You've been acting real high and mighty today, you Quirkless freak," Bakugo spat, his voice echoing off the linoleum floors. Small pops of nitroglycerin sparked in his right hand. "You think putting on some muscle and acting tough makes you suddenly on my level? You think you can go to U.A.?"

 

Izuku slowly turned his head, looking over his shoulder. His emerald eyes swept over Bakugo and his lackeys.

 

"I don't recall asking for your permission, Bakugo," Izuku said. His voice was deep, smooth, and shockingly calm. It didn't waver.

 

A collective gasp rippled through the observing students. Deku had just talked back. Deku, the punching bag, the crying weakling, had just dismissed Katsuki Bakugo with the casual tone of someone swatting a fly.

 

Bakugo’s eyes widened in sheer, blinding rage. His ego shattered like brittle glass under the weight of Izuku's apathy.

 

"You arrogant little piece of shit!" Bakugo roared, lunging forward.

 

Bakugo didn't hold back. He pulled his right arm back, generating a massive spark of explosive sweat in his palm. He aimed a devastating, point-blank right hook directly at Izuku’s face, intending to burn the defiance out of the nerd once and for all.

 

Here it is, Izuku thought.

 

Time seemed to slow down. Shadow’s brutal, agonizing training kicked in, overriding Izuku’s human instincts with the cold, hyper-analytical perception of a warrior.

 

Izuku’s kinetic vision tracked everything. He saw the telegraph in Bakugo’s right shoulder. He saw the shift in Bakugo’s hips. He saw the exact trajectory of the incoming fist, and he calculated the explosive radius based on the volume of sweat.

 

He's fast for a civilian, Izuku noted calmly, watching the glowing, orange explosion ignite in Bakugo's palm. But his form is a disaster. He is entirely reliant on the shockwave. He throws his entire body weight into the strike, leaving his center of gravity completely unprotected. Pathetic.

 

The explosion fired, a blinding flash of heat and light that engulfed the space where Izuku’s head was.

 

The students screamed.

 

But Izuku wasn't there.

 

Even wearing one hundred and twenty pounds of tungsten-steel, Izuku’s speed was completely unreadable to the untrained eye. With a fractional pivot of his left heel, Izuku slipped under the explosion. The searing heat of the blast barely ruffled his messy green hair.

 

Bakugo’s eyes widened as his fist struck empty air, his momentum carrying him forward.

 

Target acquired: Radial nerve cluster, right forearm, Izuku’s mind supplied mechanically.

 

Before Bakugo could even register that he missed, Izuku’s left hand shot up like a striking viper. He gripped Bakugo’s extended right wrist with terrifying, vice-like strength. Izuku’s thumb dug viciously into the nerve cluster just below the joint.

 

Bakugo let out a sharp, involuntary gasp of pain. His entire right arm went completely numb, the nitroglycerin sparks fizzling out instantly as his hand was paralyzed.

 

Shift momentum. Utilize his velocity against him.

 

Izuku didn't try to punch Bakugo. He didn't try to brawl. He simply stepped his right foot behind Bakugo’s leading ankle, hooking it. Izuku dropped his hips, lowering his center of gravity, and pulled Bakugo’s paralyzed arm downward and across, directly into the path of the blonde's own forward momentum.

 

It was a masterclass in judo, executed with the ruthless precision of a Shadow-taught assassin.

 

Bakugo was forcefully ripped off his feet. He was flipped entirely upside down in mid-air, a blur of ash-blonde hair and black uniform.

 

SLAM.

 

Bakugo hit the hard linoleum floor flat on his back. The impact was absolutely deafening. All the air was violently forced out of Bakugo’s lungs in a harsh, wet wheeze. His eyes rolled back slightly, his vision going white from the sheer concussive shock of the fall.

 

Before Bakugo could even attempt to recover, Izuku pivoted, bringing his heavy, tungsten-weighted boot down squarely onto the center of Bakugo’s chest, pinning him to the floor.

 

Izuku leaned his forearm on his knee, looking down at his childhood tormentor.

 

The hallway was dead silent. The silence was absolute, suffocating, and heavy with disbelief. The extending-fingers kid and the winged kid stood frozen, their jaws literally dropped, their brains completely unable to process what they had just witnessed.

 

Katsuki Bakugo, the strongest kid in school, the prodigy, the untouchable god of Aldera Junior High, was pinned to the floor, gasping for air, dismantled in less than two seconds by the Quirkless Deku.

 

Izuku stared down into Bakugo’s wide, shocked, crimson eyes. Izuku’s expression didn't change. There was no triumphant smirk. There was no boastful yelling. There was only the cold, withering disdain of a superior being.

 

"Stay out of my way, Bakugo," Izuku said, his voice a low, gravelly whisper that carried clearly in the dead silent hallway. Every syllable dripped with Shadow's uncompromising edge. "I don't have time for your childish games."

 

Izuku slowly removed his foot from Bakugo’s chest. He stood up straight, turning his back on the gasping, humiliated blonde.

 

He looked at the two lackeys. They flinched violently, taking several steps back, raising their hands in surrender.

 

Izuku let out a quiet, dismissive "Hmph," crossed his arms over his chest, and walked down the hallway.

 

The crowd of students scrambled out of his way, parting like the Red Sea. They pressed themselves against the lockers, holding their breath, terrified to even make eye contact with the green-haired boy. The aura he projected was no longer just intimidating; it was monstrous.

 

Izuku pushed open the double doors of the school and walked out into the afternoon sun.

 

Behind him, in the hallway, Bakugo finally managed to suck in a ragged breath of air. He coughed violently, rolling onto his side. He stared at the double doors where Izuku had disappeared, his hands trembling—not from the explosion, but from a profound, shattering realization.

 

Deku hadn't just beaten him. Deku hadn't even struggled. Deku had looked at him like he was nothing.

 

 

 

Later that Evening - The Midoriya Rooftop

 

The sun had set, casting the industrial skyline of Musutafu in deep purples and jagged blacks. The air was cool, a stark contrast to the heat of the day.

 

Izuku was on the concrete roof, sitting cross-legged, his breathing steady and meditative. The events of the day played through his mind, but they elicited no emotional response. He didn't feel pride over taking down Bakugo. He didn't feel vindication. He just felt a quiet, analytical satisfaction that the technique had worked exactly as intended.

 

Shadow materialized from a portal of chaotic energy a few feet away, landing silently on his skates. The hedgehog had his arms crossed, a dark, calculating look in his eyes.

 

"I reviewed the school's internal security camera footage," Shadow stated, walking over to Izuku.

 

Izuku opened his eyes, looking up at his master. "And?"

 

"Your kinetic perception was flawless," Shadow critiqued, his tone clinical. "You tracked the telegraph, analyzed the threat radius, and executed the evasion perfectly. Your strike to the radial nerve was accurate, entirely shutting down his offensive capability."

 

Izuku nodded slowly, waiting for the inevitable correction. Shadow never praised without a critique.

 

"However," Shadow continued, his eyes narrowing slightly. "You wasted kinetic energy on the throw. You utilized his momentum, yes, but you added a rotational lift to forcefully flip him onto his back. It was theatrical. It was unnecessary. A simple leg sweep combined with a downward palm strike to the clavicle would have dropped him in half the time and required less of your own muscular output."

 

Izuku absorbed the information. He replayed the memory in his mind, visualizing Shadow's suggested adjustment. The hedgehog was right. He had wanted to put Bakugo on his back to make a point, and in doing so, he had compromised pure efficiency.

 

"You are correct," Izuku said, standing up. The heavy rings clanked against his wrists and ankles. "It was inefficient. I allowed a minor psychological motive to dictate a physical action. I will correct it."

 

Shadow uncrossed his arms, a ghost of a smirk crossing his muzzle.

 

"See that you do," Shadow said softly. "The blonde brat is a big fish in a microscopic pond. He relies on brute force and fear. You shattered his paradigm today. But out in the real world, against real villains and real killers, they will not be shocked by your speed. They will try to kill you."

 

Izuku crossed his arms, staring out over the city lights.

 

"Let them try," Izuku replied, his voice a perfect echo of the Ultimate Lifeform. "I will dismantle them too."

 

For the rest of the academic year, the halls of Aldera Junior High were a very different place.

 

Nobody spoke to Izuku Midoriya. Nobody mocked him. Nobody bumped into him in the hallways. The teachers, unnerved by his intense gaze and silent demeanor, stopped calling on him in class, opting to simply pass him with top marks to avoid dealing with him.

 

And Katsuki Bakugo?

 

The explosive blonde was unusually quiet. He stopped screaming in the classroom. He stopped bullying the younger kids. Whenever Izuku entered a room, Bakugo would immediately look away, his jaw clenched so tight it looked like it might shatter. The humiliation of that single, two-second encounter had broken something fundamental in Bakugo's worldview. He realized, with a terrifying clarity, that he was not the untouchable god he thought he was.

 

Izuku didn't care. Bakugo, Aldera, the whispers—they were all just background noise.

 

He was fourteen years old. He was wearing one hundred and twenty pounds of solid tungsten. His body was a coiled spring, and his mind was a weapon. The ten months leading up to the U.A. Entrance Exam were fast approaching.

 

Izuku looked up at the stars, his emerald eyes cold and resolute. The game was about to begin. And he was going to win it on his own terms.
