What if deku had sato quirk but better

 

 

The world, as Izuku Midoriya understood it at the tender age of four, was governed by a very simple, very absolute set of rules.

 

Rule number one: All Might was the greatest hero in the entire world, an invincible titan of justice who always won with a smile.

 

Rule number two: Quirks were the most wonderful, magical things in existence, the golden tickets that allowed ordinary people to touch the realm of gods and heroes.

 

Rule number three, and arguably the most important to a four-year-old boy: Birthdays were the absolute best days of the year, primarily because they involved an exorbitant amount of sugar.

 

It was late July, and the stifling summer heat of Musutafu pressed against the windows of the Midoriya apartment, but inside, the air-conditioning was humming, and the atmosphere was electric. Today was the day. Today, Izuku was four.

 

In the living room, illuminated by the flickering, colorful light of the television screen, Izuku sat cross-legged on the carpet. He was clutching an incredibly detailed, limited-edition All Might action figure in his small, pudgy hands. On the screen, a much younger All Might was laughing amidst the roaring flames of a collapsed industrial complex, holding a dozen people on a makeshift bus carriage he had ripped from the wreckage.

 

"Fear not, citizens! Hope has arrived! Because I am here!"

 

The booming voice from the television sent familiar, thrilling shivers down Izuku’s spine. He leaned forward, his massive, dark-green eyes wide and unblinking, reflecting the bright fire on the screen. He had watched this exact video at least ten thousand times, but it never lost its magic. It was the blueprint of his soul, the singular guiding light of his nascent ambition.

 

"Izuku! Sweetie, it’s time!"

 

The voice of his mother, Inko Midoriya, drifted from the kitchen, accompanied by the clinking of ceramic plates and the unmistakable, heavenly aroma of vanilla and baked sugar.

 

Izuku scrambled to his feet, his All Might figure still gripped tightly in his left hand, and padded quickly into the small kitchen/dining area. The lights were dimmed. Inko stood beside the dining table, a radiant, teary-eyed smile on her face. In the center of the table sat a masterpiece.

 

It was a massive, three-tiered sponge cake, slathered in thick, glossy layers of rich buttercream frosting. It had been dyed in vibrant shades of primary blue, yellow, and red—the iconic colors of the Symbol of Peace. On the very top, written in sparkling golden icing, were the words: Happy 4th Birthday, Izuku! Four candles burned brightly, casting warm, dancing shadows across the room.

 

"Wow..." Izuku breathed, his jaw dropping. He practically vibrated with excitement, his green curls bouncing as he jogged to his chair and pulled himself up. "It’s an All Might cake! Mom, it’s amazing!"

 

Inko chuckled, wiping a stray tear of joy from her cheek. "Only the best for my little hero. Now, make a wish, Izuku. Think about what you want more than anything in the whole wide world, and blow out the candles."

 

Izuku didn't even have to think. He squeezed his eyes shut, clutched his action figure to his chest, and wished with every fiber of his being, with every ounce of his small, four-year-old soul.

 

Please, he thought, please let me get an amazing Quirk. Let me be strong, and fast, and brave. Let me be a hero who can save everyone with a smile, just like All Might!

 

He opened his eyes, leaned forward, and blew with all his might. The four little flames snuffed out in an instant.

 

Inko clapped her hands in delight, immediately moving to turn the kitchen lights back on. "Perfect! Now, who's ready for a slice?"

 

"Me! Me! The biggest slice, please!" Izuku cheered, banging his small fists on the table in eager anticipation.

 

Inko obliged, taking a large, serrated knife and cutting a truly generous wedge of the cake. It was a corner piece, heavy with thick blue and yellow buttercream, the sponge inside dense and moist, layered with strawberry jam. She slid the massive slice onto a smaller plate and set it gently in front of him, handing him a fork.

 

Izuku didn't hesitate. He dug the fork into the soft cake, capturing a huge chunk of sponge, jam, and frosting, and shoved it into his mouth.

 

The taste was incredible. It was a sudden, violent explosion of sweetness. The rich, fatty butter, the sharp tang of the strawberry, and the overwhelming, glorious rush of pure, unadulterated sucrose washed over his taste buds. He swallowed heavily, immediately diving back in for a second bite, then a third. Within seconds, half the massive slice was gone, his cheeks smeared with blue frosting.

 

"Slow down, Izuku, you'll give yourself a stomachache," Inko laughed, turning her back to the table to walk toward the kitchen counter to fetch herself a slice.

 

Izuku opened his mouth to reply, to tell her that it was the best cake ever.

 

But the words never came.

 

Instead, a profound, terrifying, and utterly exhilarating sensation seized him.

 

It started in his stomach—a sudden, intense heat, like someone had struck a match and dropped it into a pool of gasoline. The heat didn't just sit there; it exploded outward, rocketing through his bloodstream, racing up his spine, and flooding into his brain.

 

Izuku gasped, dropping his fork. It clattered loudly against the ceramic plate.

 

Thump-thump.

 

His heartbeat, normally a quiet, steady rhythm, suddenly sounded like a war drum in his ears. The sound was deafening.

 

THUMP-THUMP. THUMP-THUMP.

 

Everything changed. The world around him... stopped. Or rather, it slowed down to an impossible, agonizing crawl. He could see a single particle of dust drifting lazily through the air, illuminated by the kitchen light. He could hear the hum of the refrigerator motor, but the sound was stretched out, a deep, resonant groan.

 

He looked at his hands. They were trembling, but not from fear. They were vibrating with an excess of kinetic energy. He felt like his skin was too tight, like the muscles beneath were swelling, hardening, demanding to be used.

 

But the physical sensation was nothing compared to what was happening inside his head.

 

His brain felt like it had been dipped in ice water and then struck by lightning. A fog he hadn't even known was there suddenly evaporated. His thoughts, usually the simple, disjointed musings of a toddler, accelerated to a terrifying velocity.

 

Cake. Sugar. Carbohydrates. Digestion. Bloodstream. Energy. Too much energy. Need to move. Kinetic output required. Heart rate elevated. Pupils dilated. Auditory reception increased by 400%. Tactile sensitivity peaking.

 

The thoughts fired so fast he couldn't vocalize them. He felt like a supercomputer that had just been plugged directly into a nuclear reactor.

 

He slid off his chair. His feet hit the linoleum floor.

 

At that exact moment, his hand brushed against his All Might action figure sitting on the edge of the table. The plastic toy was nudged off the edge.

 

To Izuku's hyper-accelerated perception, the toy fell in ultra-slow motion. He watched it tumble, the painted smile on All Might's face rotating downward. It hit the floor and bounced, rolling quickly beneath the massive, double-door stainless steel refrigerator in the corner of the kitchen.

 

Objective: Retrieve toy, his brain supplied instantly.

 

Izuku moved.

 

He didn't walk; he blurred. One millisecond he was standing by the table, and the next, a gust of wind rustled the tablecloth as he appeared crouched in front of the refrigerator. He didn't even feel the transition of movement. It was effortless.

 

He peered into the narrow gap beneath the fridge. There was All Might, wedged against the back wall, out of reach of his small, four-year-old arms.

 

Obstacle identified. Weight of standard double-door refrigerator: Approximately 140 kilograms. Current physical capacity: Exceeds required output.

 

Izuku didn't think about the impossibility of the task. He didn't think about the fact that he was a toddler. He simply acted on the absolute certainty burning in his veins.

 

He reached down, sliding his small, frosting-stained fingers under the bottom lip of the heavy appliance. He planted his small feet firmly on the linoleum, bent his knees slightly, and pushed upward.

 

There was a horrible screech of metal against linoleum.

 

The refrigerator, packed full of groceries, milk jugs, and vegetables, lifted off the ground as if it were made of styrofoam.

 

Izuku stood up, holding the three-hundred-pound appliance suspended in the air with both hands, lifting it a full three feet off the ground. He didn't strain. He didn't grunt. His muscles, flooded with a terrifying, instantaneous conversion of pure glucose into raw, unbridled physical power, simply obeyed his command.

 

"Izuku, sweetie, did you drop—"

 

Inko turned around, holding a plate.

 

She froze.

 

The plate slipped from her hands, shattering into dozens of pieces on the kitchen floor.

 

Her four-year-old son, standing barely a meter tall, was casually holding their entire refrigerator in the air, his eyes wide, his pupils dilated so much that the green irises were barely visible, vibrating with a frantic, terrifying energy.

 

"I-Izuku?" Inko whispered, the color draining entirely from her face.

 

Izuku looked at her. He wanted to say, Look Mom, I got a Quirk! I'm strong like All Might!

 

He opened his mouth.

 

And then, the fuel ran out.

 

The drop-off wasn't gradual. It was a cliff. The gasoline fire in his stomach was suddenly extinguished, leaving behind a freezing, desolate void.

 

The horrific realization hit his hyper-accelerated brain a fraction of a second before his body reacted.

 

Glucose levels depleted. Muscular integrity failing. Neurological crash imminent. Hypoglycemia.

 

His arms gave out. The refrigerator slammed back down onto the floor with an earth-shattering crash, the impact rattling the cabinets, popping the doors open, and sending a carton of milk exploding across the linoleum.

 

Izuku collapsed backward. The world, which had been so sharp, so bright, so impossibly slow, suddenly snapped back to normal speed, and then immediately began to dim. A violent tremor seized his tiny frame. He felt horribly, agonizingly cold. Sweat beaded on his forehead in an instant. The nausea hit him like a physical blow, his stomach twisting into agonizing knots.

 

His vision went black around the edges. His limbs felt like they were filled with wet cement.

 

"IZUKU!"

 

Inko's scream was the last thing he heard, a sound of absolute, unfiltered terror, before the darkness swallowed him whole.

 

 

 

Beep... Beep... Beep...

 

The rhythmic, sterile sound of a heart monitor was the first thing to breach the void. Then came the smell—sharp, astringent, smelling heavily of bleach and rubbing alcohol. It was the universal scent of a hospital.

 

Izuku slowly peeled his eyes open. The harsh fluorescent lights of the ceiling made him wince, and he immediately squeezed them shut again, letting out a small, dry groan. His entire body ached. It wasn't the sharp pain of a scrape or a bruise, but a deep, throbbing soreness that seemed to radiate from his very bones. His muscles felt utterly exhausted, as if he had just run a marathon while wearing a backpack full of rocks.

 

"Izuku? Oh, thank goodness. Sweetie, are you awake?"

 

He opened his eyes again, slower this time. His mother was leaning over the bed, her face puffy and red from crying. She gently stroked his unruly green curls, her hand trembling slightly.

 

"Mom...?" Izuku rasped, his throat incredibly dry. "Water... please."

 

Inko quickly poured a small cup of water from a plastic pitcher on the bedside table, supporting his head as he drank greedily. The cool liquid felt like a blessing.

 

As his vision cleared, he realized he was in a private hospital room. He had an IV line hooked into the back of his left hand, feeding a clear fluid into his veins.

 

"Where... what happened?" he mumbled, his mind sluggish. The hyper-clarity he had felt earlier was completely gone, replaced by a dense, foggy lethargy.

 

Before Inko could answer, the door to the room clicked open. A doctor stepped in, holding a digital tablet. He was a slightly older man with a kind face, wearing a white coat over a beige sweater vest.

 

"Ah, the sleeping beauty awakens," the doctor said with a gentle smile, walking over to the foot of the bed. "I am Doctor Tsubasa. It's very nice to meet you, Izuku. How are you feeling?"

 

"Tired," Izuku answered honestly. "And my arms hurt."

 

Dr. Tsubasa nodded sympathetically, tapping a few things on his tablet. "I'm not surprised. You put your body through quite an ordeal, young man." He looked up at Inko. "Mrs. Midoriya, if you're ready, I have the results of Izuku's blood tests and quirk registry analysis."

 

Inko tensed, her hands clasping together tightly in her lap. "Is he... is he okay, Doctor? When he collapsed, he was shaking so badly, and his skin was cold like ice..."

 

"He is stable now," Dr. Tsubasa reassured her quickly. "The IV is pumping a steady stream of glucose and electrolytes into his system. What Izuku experienced was a severe, acute hypoglycemic crash. Essentially, his blood sugar dropped to dangerously low levels in a matter of seconds."

 

"But he had just eaten cake!" Inko protested, bewildered. "Half a slice of a very rich buttercream cake. How could his blood sugar drop?"

 

Dr. Tsubasa pulled up a chair and sat down, his expression turning serious, yet laced with a profound scientific fascination. "Because, Mrs. Midoriya, your son has just manifested his Quirk. And it is, without a doubt, one of the most fascinating and potent physiological mutations I have seen in my career."

 

Izuku's ears perked up despite his exhaustion. Quirk? He had a Quirk! The thought pushed away a layer of the fog in his mind.

 

"A Quirk?" Inko gasped, a hand flying to her mouth. "But... neither my husband nor I have anything like what he did. I can pull small objects toward me, and Hisashi breathes fire. Izuku lifted our refrigerator! It weighs hundreds of pounds!"

 

"Quirks are genetic lotteries, Mrs. Midoriya," Dr. Tsubasa explained, bringing up a complex biological diagram on his tablet and showing it to her. "Sometimes, genes combine in unexpected ways, or a complete mutation occurs. In Izuku's case, it's a metabolic anomaly. Does anyone in your extended family have a food-based or enhancement Quirk?"

 

Inko thought for a moment. "My great-grandfather had a Quirk that let him stay awake for days if he drank black tea, but that’s it."

 

"Fascinating," the doctor muttered. He turned his attention back to Izuku. "Izuku, what exactly did you feel right after you ate that cake?"

 

Izuku swallowed, trying to find the words to describe the indescribable. "I felt... hot. But a good hot. Like my tummy was on fire, but it didn't burn. And then... everything got really slow. I could see the dust in the air. I could hear the fridge humming really loudly. And my brain felt like it was going super, super fast. I knew exactly how heavy the fridge was, and I just knew I could lift it to get my toy."

 

Dr. Tsubasa’s eyes widened slightly, and he rapidly tapped notes into his tablet. "Hyper-cognition combined with extreme physical enhancement," he murmured to himself. "Remarkable."

 

He looked back at Inko. "Mrs. Midoriya, to put it simply, Izuku's Quirk is a highly volatile form of energy conversion. His body, specifically his digestive system and cellular structure, are mutated. When he consumes simple carbohydrates—specifically sugar—his body doesn't process it like a normal human. Instead of storing it or burning it slowly for sustained energy, his cells act like a hyper-efficient combustion engine."

 

"It converts the sugar into raw power instantly," Dr. Tsubasa continued. "Based on the blood tests, and the estimated weight of the object he lifted compared to the approximate amount of sugar in that cake, I've calculated a rough hypothesis. For every ten grams of sugar Izuku processes, his physical strength, his speed, and miraculously, his neurological firing speed—his brain processing power—are multiplied exponentially. We're talking a multiplier of ten, perhaps more."

 

Inko stared at him, horrified. "Multiplier? You mean... he gets ten times stronger and faster just from eating a candy bar?"

 

"Essentially, yes," Dr. Tsubasa nodded. "There are documented Quirks similar to this. There is a young boy a few towns over, Rikido Sato, whose Quirk grants him a five-times strength boost when he consumes ten grams of sugar. However, young Sato's Quirk has a severe drawback: the sugar fuels only his muscles, and as a result, his brain is starved of oxygen and energy, causing cognitive decline. He becomes sluggish and somewhat mindless while using it."

 

The doctor pointed a pen at Izuku. "Izuku’s Quirk is vastly superior, and entirely different. The sugar fuels everything. His brain enters a state of hyper-analysis, operating like a supercomputer. His muscles undergo instantaneous hypertrophy, increasing fiber density to withstand immense loads without tearing, while his reflexes become virtually instantaneous."

 

Izuku grinned weakly, looking at his hands. I'm strong. I'm smart. I'm going to be a hero.

 

"But," Dr. Tsubasa's voice darkened, cutting through Izuku's joy like a knife, "there is a severe, and potentially lethal, drawback. And it is the reason he is in this hospital bed."

 

Inko gripped the edge of the mattress. "The crash."

 

"Exactly," Dr. Tsubasa said gravely. "Izuku's metabolism burns incredibly hot, and unbelievably fast. The cake he ate provided a massive surge of power, but because he exerted himself by lifting that refrigerator, he burned through that fuel in a matter of seconds. When the sugar is gone, the Quirk shuts off abruptly. The resulting crash forces his body into severe hypoglycemia."

 

The doctor leaned forward, looking Izuku directly in the eyes. "Izuku, you need to listen to me very carefully. Your Quirk is powerful, but it is dangerous to your own body. If you use your power, and you run out of sugar, your body will begin to panic. You will experience violent shaking, extreme fatigue, nausea, and blackouts. If you push yourself too hard while in that state, your cells will begin to cannibalize themselves for energy. You could suffer severe muscle tearing, temporary paralysis, or slip into a diabetic coma that you might not wake up from."

 

The room fell deathly silent. The only sound was the steady beep of the heart monitor.

 

Izuku stared at the doctor, the heavy reality of the words sinking into his four-year-old mind. The power wasn't free. It was a trade. A dangerous, violent trade.

 

Inko burst into tears, leaning over and burying her face in the hospital blankets near Izuku's legs. "My baby... my poor baby..."

 

"Mrs. Midoriya, please, don't despair," Dr. Tsubasa said gently, placing a hand on her shoulder. "This is entirely manageable. But it will require strict discipline. Izuku cannot eat like a normal child. He needs a highly specialized, heavily regulated diet. His basal metabolic rate even when not using his Quirk is higher than average. He needs a constant, slow-release intake of complex carbohydrates to maintain his baseline health, and he must carry concentrated, fast-acting sugars on his person at all times in case of an emergency."

 

"We will register his Quirk officially," the doctor concluded, standing up. "For now, we will call it Hyper-Metabolism. We will assign him a dietician. With the right care, he will live a perfectly normal life."

 

A normal life, Izuku thought, staring at the ceiling as the doctor left the room and his mother continued to weep softly.

 

He didn't want a normal life. He wanted to be a hero. He wanted to be All Might.

 

He closed his eyes, remembering the sensation. The absolute clarity. The unstoppable power. It was terrifying, yes. It was dangerous. But it was his.

 

He would just have to learn how to control the fire, before it burned him alive.

 

 

 

A week had passed since the incident. Izuku had been discharged from the hospital with a strict dietary regimen, a small, insulated pouch strapped to his belt containing specifically measured hard candies and a glucose-injection pen, and a mother who hovered over him with the anxiety of a hen guarding her only chick.

 

It was a sunny Tuesday afternoon. The local playground was bustling with children from the neighborhood. The air was filled with the sound of laughter, the squeak of the swings, and the occasional, sharp CRACK of miniature explosions.

 

Katsuki Bakugo was holding court in the sandbox.

 

Even at four years old, Katsuki possessed an aura of absolute dominance. He had recently manifested his Quirk—Explosion—and he had spent the last three days ensuring every single child in the neighborhood knew exactly how amazing it was. He was currently demonstrating, holding his small palms out and letting loose a barrage of loud, popping sparks that smelled strongly of burnt caramel and ozone.

 

His two lackeys, a boy with leathery wings and a boy with extendable fingers, watched in awe.

 

"So cool, Bakugo!" the winged boy cheered. "You're definitely gonna be a pro hero!"

 

"Duh," Katsuki scoffed, a feral, confident grin stretching across his face. He wiped a smudge of soot from his cheek. "I'm not just gonna be a pro. I'm gonna be the Number One hero! I'm gonna surpass All Might, and I'm gonna be the richest, strongest guy in the world. My Quirk is unbeatable!"

 

Izuku stood at the edge of the playground, watching Katsuki.

 

Before his birthday, Izuku would have approached Katsuki with a mixture of awe and timid hesitation. They had been friends since they were babies, their mothers being close, but Katsuki had always been the leader, the loud, aggressive alpha of their small pack. When Katsuki got his Quirk, the dynamic had shifted. Katsuki had begun referring to the quirkless kids with a sneer, a look of superiority that Izuku had dreaded being directed at him.

 

But Izuku wasn't quirkless. And after what he had experienced, after feeling the god-like power surge through his veins and the terrifying intellectual clarity it brought, Izuku didn't feel timid anymore. He felt different. He felt... calculated.

 

He reached down to his belt pouch and unzipped it. Inside were a dozen small, wrapped hard candies. The dietician had explained that these specific candies were formulated with pure glucose—four grams each. Just enough to give him a mild boost without risking a catastrophic crash, provided he didn't exert himself for more than a minute.

 

Izuku unwrapped a cherry-flavored candy and popped it into his mouth.

 

He didn't chew it. He just let it sit on his tongue, letting the sugar slowly dissolve into his saliva.

 

The change wasn't as violent as the cake, but it was immediate. The world sharpened. The colors of the playground slides became more vivid. The ambient noise of the wind and the traffic in the distance separated into distinct, analyzable audio streams. His posture straightened. The slight, nervous tremble in his hands vanished, replaced by a steady, thrumming hum of energy beneath his skin.

 

He walked forward, his steps measured and precise, until he reached the edge of the sandbox.

 

"Kacchan," Izuku said. His voice was calm, lacking the usual high-pitched waver of a four-year-old seeking approval.

 

Katsuki stopped his explosions and looked up, his crimson eyes narrowing. He assessed Izuku, his sharp instincts immediately picking up on the change in his friend's demeanor. "Izuku. You haven't been around for a week. Auntie Inko said you were sick."

 

"I wasn't sick," Izuku replied evenly. "I got my Quirk."

 

The playground went silent. The lackeys looked at Izuku, then at Katsuki.

 

Katsuki stood up, brushing the sand off his shorts. He stepped out of the sandbox, walking up to Izuku until they were toe-to-toe. Katsuki was slightly taller, but Izuku didn't flinch or look away. He met Katsuki's fierce red gaze with unblinking, emerald intensity.

 

"Is that so?" Katsuki challenged, crossing his arms. "What is it, then? Can you make things float like Auntie Inko? Can you breathe some pathetic little fire like your dad?"

 

"No," Izuku said. He shifted the candy to the other side of his mouth. "It's a mutation. It makes me stronger and faster."

 

Katsuki scoffed loudly. "A basic enhancement Quirk? Boring. And useless against my explosions. I can blast you away before you even get close."

 

"I don't think so," Izuku said simply.

 

It wasn't a boast. It was a statement of fact, delivered with the cold, analytical certainty of a brain operating on pure, hyper-processed glucose.

 

Katsuki’s eyes flared with irritation, a spark popping angrily in his right palm. "You calling me a liar, Izuku? You think you're better than me?!"

 

"I'm not calling you a liar, Kacchan. I'm just stating a tactical probability based on the activation speed of your sweat glands versus my kinetic output."

 

Katsuki blinked. The winged lackey scratched his head. Neither of them understood half the words Izuku had just said.

 

"Speak Japanese, nerd!" Katsuki yelled, winding up his right arm. He didn't intend to hurt Izuku badly, just to scare him, to re-establish the hierarchy. He swung his open palm toward Izuku's shoulder, intending to let off a loud, smoky pop right next to his ear.

 

Izuku saw the muscle in Katsuki's shoulder twitch. He saw the shift in Katsuki's weight. To Izuku's accelerated mind, the punch was moving through molasses.

 

Trajectory calculated. Impact point: Left deltoid. Threat level: Minimal. Evasion unnecessary. Interception optimal.

 

Izuku raised his left hand.

 

Smack.

 

Katsuki's hand was stopped dead in its tracks, caught firmly in Izuku's small grip. The explosion went off—POP—but Izuku's grip was like a steel vise. The small flash of heat singed the hairs on Izuku's arm, but he didn't even blink. He just stood there, holding Katsuki's arm in the air, his green eyes locked onto Katsuki's shocked red ones.

 

Katsuki tried to yank his arm back. It didn't budge. He strained, gritting his teeth, his face turning red. Izuku held him in place effortlessly.

 

"Your explosions are powerful, Kacchan," Izuku said, his voice quiet but carrying a strange, unnatural resonance. "But they require a physical motion to aim and execute. If I neutralize the limb before the ignition sequence completes, your offensive capability drops by fifty percent."

 

Katsuki stopped pulling. He stared at his trapped hand, then up at Izuku's face.

 

He didn't see the timid, crybaby Izuku he was used to. He saw a predator. He saw calculating, emerald eyes that were analyzing him, taking him apart, and figuring out exactly how to dismantle him.

 

For a fraction of a second, Katsuki felt genuine fear.

 

Then, the fear vanished, instantly incinerated by a massive, surging wave of adrenaline and ferocious excitement.

 

A wide, feral, almost manic grin split Katsuki's face. He let out a breathless laugh.

 

"You..." Katsuki breathed, finally wrenching his arm free as Izuku voluntarily let go. "You've been holding out on me, you damn nerd!"

 

Izuku stepped back, crunching down on the remaining piece of the hard candy and swallowing it. He knew he had about three minutes before the minor crash hit, so he needed to conclude this interaction quickly.

 

"I only just got it, Kacchan," Izuku said, feeling the hyper-focus begin to waver slightly at the edges. "And it has limits. But I'm going to be a hero. Just like you."

 

Katsuki didn't sneer. He didn't mock him. He didn't call him a useless, wooden doll. The word Deku—a nickname Katsuki had been workshopping in his head for the past few days to mock Izuku if he turned out to be quirkless—died in his throat, completely irrelevant now.

 

Instead, Katsuki slammed his fists together, a large explosion crackling between them.

 

"Alright then," Katsuki declared, his voice loud enough for the whole playground to hear. "Listen up, Izuku! You're strong. Maybe you're a genius now, whatever. But don't you dare think you're better than me! I'm still gonna be Number One! And if you get in my way, I'll blast you to pieces!"

 

Izuku felt the familiar ache beginning in his joints, the cold sweat starting to prickle at his hairline. The sugar was running out. But he smiled—a genuine, confident smile.

 

"I won't lose to you, Kacchan. It's a promise."

 

Katsuki snorted, turning around and marching back to the sandbox. "We'll see, Sugar-Freak. We'll see."

 

Izuku turned and walked away, heading toward the nearest bench to sit down before the fatigue fully hit him. He pulled out a small, slow-release carbohydrate bar his dietician had recommended and took a bite, chewing methodically.

 

As he sat there, feeling the agonizing drop in his cognitive speed, feeling his brain revert from a supercomputer back to a normal four-year-old's mind, he made a silent vow.

 

Katsuki relied on instinct and raw, explosive talent.

 

Izuku couldn't afford to do that. His Quirk was a scientific equation. Input equals output. But the output was toxic if mismanaged.

 

If he wanted to be the best, if he wanted to stand beside All Might, he couldn't just rely on eating candy and punching hard. He had to be smarter than his Quirk. He had to understand his body on a molecular level.

 

He looked down at his small hands.

 

I need to learn, he thought, the remnants of the sugar-fueled hyper-cognition cementing the idea into his long-term memory. I need to learn chemistry. I need to learn biology. I need to learn nutrition.

 

And, perhaps most importantly... he needed to learn how to bake.

 

 

 

The years that followed were not the typical childhood of a boy aiming for U.A. High School.

 

While Katsuki Bakugo spent his elementary and early middle school years picking fights, honing his combat instincts, and solidifying his reputation as the undisputed king of Aldera Junior High, Izuku Midoriya took a vastly different path.

 

Izuku still loved heroes. His bedroom was still plastered floor-to-ceiling with All Might posters. He still mumbled to himself, keeping copious, wildly detailed journals on every pro hero he saw on the news.

 

But alongside the hero merchandise, Izuku's room looked more like a university student's laboratory.

 

Stacks of heavy, intimidating textbooks dominated his desk: Advanced Human Anatomy, Cellular Biology and ATP Synthesis, Nutritional Biochemistry, and The Thermodynamics of Quirks.

 

Izuku, at the age of twelve, was an anomaly. In standard social situations, he was quiet, polite, and deeply observant. He didn't seek out conflict, mostly because he knew that if he got into a fight and was forced to use his Quirk, the collateral damage—to his opponent and to his own body—would be catastrophic.

 

His relationship with Bakugo remained an intense, abrasive rivalry. Bakugo was loud and aggressive, constantly challenging Izuku, calling him "Nerd" or "Sugar-Freak". But it was never bullying. Bakugo knew exactly what Izuku was capable of. They had sparred a few times over the years in supervised dojos, and Bakugo had learned the hard way that when Izuku consumed sugar, trying to fight him in close quarters was like trying to box a hurricane. Izuku would dodge explosions with millimeter precision and strike back with force that bruised Bakugo's ribs through his guard.

 

But Izuku rarely used his Quirk if he could help it.

 

The crashes were brutal. As Izuku grew, his Quirk matured, and the multiplier scaled with his natural physical development. A candy bar that used to give him the strength to lift a fridge now gave him the power to shatter concrete. But the toll on his body scaled as well.

 

He learned early on that commercial sweets were practically useless for hero work.

 

A standard chocolate bar was full of fats, emulsifiers, and complex proteins that slowed down digestion. It took too long to hit his bloodstream, the power curve was unpredictable, and the volume of food required to achieve a high multiplier made him nauseous if he tried to fight on a full stomach. Furthermore, pure, raw sugar spiked his power too violently, leading to a crash so steep it often left him temporarily paralyzed with muscle cramps.

 

He needed efficiency. He needed control.

 

So, Izuku took over the Midoriya kitchen.

 

It was a rainy Saturday afternoon, and fourteen-year-old Izuku was standing at the kitchen counter, wearing a beige apron dusted with powdered sugar and cornstarch. His green hair was tied back with a bandana, and he wore clear safety goggles.

 

On the stove, a saucepan was bubbling furiously. Inside was a thick, viscous liquid that looked like molten ruby.

 

"Temperature is at 115 degrees Celsius. Soft ball stage," Izuku muttered to himself, his eyes locked on a digital candy thermometer clipped to the side of the pan. He reached out with a pair of tongs, pulled out a small amount of the syrup, and dropped it into a bowl of ice water. He fished it out with his fingers, squeezing the pliable red lump. "Perfect viscosity."

 

He turned off the heat and quickly moved the saucepan to a heat-proof mat. He grabbed a small, precisely measured vial of clear liquid from the counter.

 

"Adding the proprietary blend," he narrated quietly, acting as if he were recording a scientific log. "Ten milliliters of concentrated liquid caffeine, five milligrams of synthesized adrenaline—legally procured via medical Quirk exemption—and a highly condensed dose of pure, crystallized maltodextrin for a stabilized absorption rate."

 

He poured the vial into the molten candy. It hissed and bubbled violently, the color shifting from ruby red to a glowing, translucent crimson. He grabbed a whisk and stirred rapidly, ensuring an even distribution on a molecular level.

 

Once mixed, he carefully poured the hot liquid into a series of silicone molds shaped like small, geometric diamonds.

 

"Batch number forty-two," Izuku said, wiping his brow with the back of his arm. "The 'Red Gummy' prototype. Designed for instantaneous, maximum muscular hypertrophy and pain suppression, with a controlled, three-minute burn time and a buffered comedown to prevent severe hypoglycemic shock."

 

Inko walked into the kitchen, carrying a basket of laundry. She paused, looking at the glowing red candies cooling on the counter, then at the flour-covered state of her son.

 

She sighed, a mixture of exasperation and deep affection. "Izuku, honey, please tell me you didn't use the good saucepan for your combat experiments again. It took me a week to scrub the last batch of your 'blue speed-mints' out of the Teflon."

 

Izuku flushed, rubbing the back of his neck sheepishly. "Sorry, Mom. But this batch is different! I finally cracked the lipid-barrier problem. These gummies will dissolve directly into my mucosal membranes. I won't even have to digest them. The power will hit my bloodstream in less than two point five seconds."

 

Inko set the laundry basket down and walked over, placing a gentle hand on his shoulder. "I know you're working hard, Izuku. You're brilliant, you know that? The dietician said your understanding of biochemistry is already at a university level."

 

She looked at the red gummies, a shadow of worry crossing her face. "I just... I worry about what you're putting into your body. Adrenaline? Caffeine? Concentrated glucose? It's like you're building tiny bombs for your heart."

 

Izuku’s expression softened. He took off his goggles and looked at his mother. "I know it's dangerous, Mom. But the entrance exam for U.A. is only ten months away. The practical exam is notorious for physical combat against robotics. My base physical strength is good—I've been working out every day—but it's not enough to destroy heavy machinery."

 

He pointed to the cooling candies. "My Quirk is a multiplier. Zero multiplied by anything is still zero. So I train my body to raise the base number. But to be a hero, to save people like All Might does, I need the multiplier. And I need to control it perfectly. These candies... they're my support gear. They're my weapons."

 

Inko looked into her son's eyes. They were the same large, emerald eyes he had as a toddler, but the innocent, naive wonder had been replaced by a fierce, calculating, and unyielding determination. He wasn't a reckless child. He was a scientist preparing for war.

 

She smiled softly, reaching up to brush a streak of powdered sugar off his cheek. "Okay. Just... promise me you won't test the red ones without supervision. Remember what happened with the Jawbreaker prototype last year?"

 

Izuku shuddered at the memory. He had formulated a massive, ultra-dense jawbreaker designed for sustained, long-term power. He had tested it in a scrap yard, punched a junked car into the stratosphere, and then suffered a crash so violent he had been bedridden for three days with microscopic tearing in his bicep.

 

"I promise, Mom," Izuku said sincerely. "No testing the heavy artillery until I'm in a controlled environment."

 

"Good," Inko said, picking up her laundry basket. "Now, clean up this kitchen before dinner. We're having katsudon. You need your slow-burn carbs for your evening run."

 

"Yes, Mom!"

 

As Inko left the kitchen, Izuku turned his attention back to the counter. He carefully popped one of the cooled, diamond-shaped Red Gummies out of the silicone mold. It was firm, yet slightly yielding, glittering in the overhead light like a precious gem.

 

He held it between his thumb and forefinger, feeling the dense weight of the concentrated calories.

 

Ten months until the U.A. entrance exam.

 

He didn't have a Quirk that let him shoot fire or create explosions from thin air. He didn't have a Quirk that altered the laws of gravity or hardened his skin to steel.

 

He had a metabolism that ran like a nuclear reactor, and a brain that operated on hyper-speed when fueled by sugar.

 

He grabbed a small, customized utility belt he had been working on. It was made of tough, black canvas, lined with rows of small, waterproof, hermetically sealed pouches.

 

He slipped the Red Gummy into the pouch marked with a red stripe.

 

In the adjacent pouches were other prototypes.

 

Blue Gummies: Laced with pure caffeine and fast-acting monosaccharides, designed to maximize his neurological firing speed and reflex time for evasion and speed, sacrificing raw strength.

 

Yellow Hard Candies: Pure glucose, slow-dissolving, designed for sustained, low-level hyper-cognition. Perfect for taking written exams or analyzing crime scenes without physical burnout.

 

Green Chocolates: Packed with complex carbohydrates, fats, and a tiny amount of sugar, designed to be eaten after a fight to aggressively combat the hypoglycemic crash and stabilize his blood sugar.

 

Izuku strapped the belt around his waist. He looked at his reflection in the dark glass of the oven door.

 

He saw a boy who had spent the last ten years studying, baking, exercising, and analyzing. He saw a boy who understood that true power wasn't just given; it was formulated, refined, and controlled.

 

He reached into his pocket and pulled out a simple, store-bought peppermint. He unwrapped it and popped it into his mouth.

 

As the sugar dissolved, he felt the familiar, glorious rush. The hum of the refrigerator sharpened into focus. The dust motes in the air slowed to a crawl. His muscles tightened, thrumming with kinetic potential. His brain clicked into a higher gear, calculating the exact nutritional value of the katsudon his mother was about to make, cross-referencing it with his planned caloric expenditure for a ten-kilometer run.

 

Izuku Midoriya smiled, his green eyes glowing with an intense, analytical fire.

 

Ten months, he thought, moving at a blur to grab a sponge and begin scrubbing the counters at superhuman speed, finishing the entire kitchen in under five seconds.

 

He was ready. U.A. wasn't going to know what hit them.

 

 

The steady, monotonous drone of the middle school teacher’s voice was, to Izuku Midoriya, the closest auditory equivalent to watching paint dry.

 

"—and since you are all third-year students, it is time to start thinking seriously about your futures and what career paths you intend to pursue."

 

Izuku sat near the back of the classroom at Aldera Junior High, his chin resting heavily in the palm of his hand. He wasn't bored because the material was difficult; he was bored because his brain, even operating at its baseline metabolic rate, processed information at a speed that made normal human conversation feel excruciatingly sluggish.

 

He glanced at the clock on the wall. The second hand ticked forward. Tick... tick... tick...

 

Izuku reached into his pocket and pulled out a small, foil-wrapped square. It was a stabilized, slow-release complex carbohydrate chew—a concoction of oats, honey, and a highly condensed maltodextrin polymer he had spent three weeks perfecting in his kitchen. He slipped it under his surgical mask (a common accessory he wore to hide his constant chewing and muttering) and popped it into his mouth, letting it sit against his cheek.

 

Instantly, his body recognized the fuel. His basal metabolic rate, which naturally ran hot enough to give him a resting body temperature of 37.5 degrees Celsius, purred like a finely tuned engine.

 

"I could hand out these career aptitude forms," the teacher continued, holding up a stack of paper, a wry smile crossing his face. "But why bother? I know you all want to go into the hero track!"

 

The classroom erupted. Students leaped from their desks, cheering, showing off their quirks. A girl elongated her fingers; a boy shot small bursts of water from his nose; another hardened his skin into a rocky texture. It was a cacophony of minor, flashy mutations.

 

"Yes, yes, you all have wonderful Quirks," the teacher sighed, trying to wave them down. "But remember, using your powers in school is against the rules—"

 

"Hey, teach!" a loud, brash voice cut through the noise like a chainsaw. "Don't lump me in with these background characters!"

 

Katsuki Bakugo leaned back in his chair, his feet kicked up onto his desk, a sneer of absolute confidence on his face. He let off a small, sharp explosion in the palm of his hand—CRACK—causing the students around him to flinch.

 

"I'm not going to some second-rate agency to be a sidekick," Bakugo declared, his red eyes scanning the room. "I aced all the mock tests. I'm the only one here with the raw power and the instincts to make it into U.A. High School. I'm going to surpass All Might, and I'll become the top-ranked hero in the world!"

 

The class murmured in a mix of awe and annoyance.

 

"Ah, yes, Bakugo," the teacher said, looking at a clipboard. "You are indeed aiming for U.A. Your test scores are exceptional." The teacher paused, his eyes drifting across the page. "Oh. Midoriya, you’re applying for U.A. too, right?"

 

The room fell dead silent.

 

Then, all eyes slowly turned toward the back of the room. Izuku didn't flinch. He didn't cower. He just sat there, chewing slowly on his carb square, his emerald eyes calmly meeting the stares of his classmates.

 

"Yes," Izuku said simply, his voice clear and unwavering.

 

"Midoriya? U.A.?" a boy scoffed from the front. "Are you kidding me?"

 

"I mean, sure, he's smart, but his Quirk is a suicide switch!" another whispered loudly. "I heard he broke his own arm trying to lift a car when we were eight. What's he gonna do, eat a candy bar and die of a heart attack during the exam?"

 

Izuku ignored them. He had heard it all before. His Quirk, Hyper-Metabolism, was registered publicly, but the intricacies of it were kept vague. Most people just thought he had a strength enhancement that made him sick afterward. They didn't understand the chemistry. They didn't understand the math.

 

Bakugo, however, didn't laugh. He slowly lowered his feet from the desk and turned to face Izuku.

 

"Hey, Sugar-Freak," Bakugo growled, the ambient heat in the room rising as his palms sparked. "You think you can compete with me? You think a few lab experiments in your mom's kitchen make you U.A. material?"

 

Izuku finished his chew and swallowed. The minor influx of glucose sharpened his senses. He looked at Bakugo, his mind instantly mapping the distance between them (4.2 meters), analyzing Bakugo's posture (aggressive, weight shifted forward, prime for a right-handed vault over the desk), and calculating the required milligram dosage of caffeine to outpace Bakugo's initial explosive burst.

 

"I think," Izuku replied evenly, adjusting his notebook, "that my kinetic output at a ten-gram sucrose conversion rate exceeds your maximum explosive yield by approximately twenty-two percent, Kacchan. But it's not a competition between us. We're both aiming for the top."

 

Bakugo's eye twitched. "Stop talking like a damn textbook! Your output doesn't mean crap if you pass out after throwing one punch! I'll crush you in the exams, nerd. I'll prove my explosions are absolute!"

 

"I look forward to it," Izuku said, a genuine, challenging smile touching the corners of his mouth.

 

The teacher clapped his hands, breaking the tension. "Alright, settle down, both of you. The entrance exams are ten months away. Let's focus on graduation first."

 

As the bell finally rang, dismissing them for the day, Izuku packed his bag with methodical precision. He slung his heavy yellow backpack over his shoulders and adjusted his customized utility belt hidden beneath his school uniform jacket.

 

He walked out of the school gates, taking a detour away from the main streets. He preferred the quieter routes; the ambient noise of a busy city street was often overwhelming if he accidentally bit into something sweet and triggered his hyper-sensory state.

 

Today, his mind was completely occupied with his latest project.

 

The lipid-barrier on the Red Gummies is stable, he muttered to himself, pulling out a battered, heavily modified notebook titled Hero Analysis for the Future: Vol. 13 - Chemical Enhancements. But the post-metabolic crash is still too steep. If I increase the complex carbohydrate buffer by three percent, it might slow the descent into hypoglycemia, but it could also blunt the initial ten-times multiplier. I need raw, explosive power to take down the U.A. robots. Armor plating requires massive concussive force to shatter.

 

He walked into a dark, concrete tunnel beneath an overpass, his eyes glued to his chemical equations.

 

"A medium-sized villain like me needs a medium-sized meat-suit..."

 

The voice was wet, guttural, and echoed horribly off the curved walls of the tunnel.

 

Izuku stopped dead in his tracks.

 

Auditory anomaly detected, his brain registered instantly, though it was still operating at normal human speed. Source: Behind. Distance: Two meters. Threat level: Unknown.

 

He spun around. Rising from the city sewer grate was a horrific mass of dark green, viscous sludge. It smelled of sewage, rotting garbage, and stagnant water. Two massive, bulbous eyes and a jagged mouth full of mismatched teeth floated within the liquid mass.

 

"You'll do perfectly, kid," the Sludge Villain hissed, lunging forward with terrifying speed, a wave of liquid muck reaching out to engulf Izuku.

 

Izuku didn't panic. Panic was an emotional response, and emotions clouded calculations.

 

His hand moved to his utility belt with practiced, muscle-memorized perfection. He unzipped the pouch marked with a blue stripe. He extracted a "Blue Gummy"—a soft, gel-like candy formulated with pure glucose, high-dose caffeine, and a trace amount of fast-acting vasodilators.

 

He tossed it into his mouth and bit down.

 

The liquid center burst over his tongue.

 

0.1 seconds: The glucose bypassed his digestive tract, absorbing directly through the mucosal lining of his mouth and sublingual veins.

0.2 seconds: His heart rate spiked from 70 beats per minute to 180.

0.3 seconds: The world stopped.

 

The rushing wave of sludge, which had been traveling at roughly thirty miles per hour, froze in mid-air. Izuku could see the individual droplets of filthy water suspended between him and the monster. He could hear the low, stretched-out, demonic bass of the villain's roar.

 

His brain fired on all cylinders. The fog of humanity lifted, replaced by the terrifying, crystal-clear coldness of the Hyper-Metabolic State.

 

Threat Assessment: Fluid-based villain. Physical strikes with blunt force will be ineffective; energy will disperse through the liquid medium. Vulnerability: Core structure. Eyes and teeth are solid constructs. Target identified.

 

Izuku shifted his weight. His muscles didn't bulge like a bodybuilder's; instead, they tightened, the fibers condensing and compressing into cables of high-tensile steel.

 

He ducked beneath the frozen wave of sludge. Moving at a speed that would appear to a normal human as nothing more than a green blur, he stepped inside the villain's guard.

 

Calculated strike. Minimal force required. Goal: Stun and evade.

 

Izuku brought his hands together, clapping them directly in front of the villain's oversized left eye.

 

The resulting shockwave—fueled by the rapid, violent expansion of kinetic energy from his hyper-dense muscles—created a localized sonic boom in the confined space of the tunnel.

 

BOOM!

 

To Izuku, it felt like pushing through thick molasses, but as the world snapped back to normal speed, the effect was devastating. The concussive blast of air hit the villain's eye point-blank.

 

"AGGGHHHH!" the Sludge Villain shrieked, the sheer force of the air pressure blowing a massive hole in his liquid body and sending him reeling backward, his form splattering against the concrete walls.

 

Izuku didn't stick around to fight a fluid enemy he couldn't grasp. He immediately turned and sprinted out of the tunnel, his legs pumping with pneumatic force, carrying him fifty meters into the sunlight in a fraction of a second.

 

He came to a screeching halt, his rubber soles smoking against the pavement.

 

And then, the Blue Gummy ran out.

 

The crash wasn't as violent as a strength-candy crash, but it was sudden. His heart rate plummeted. A wave of dizziness washed over him, and his vision blurred. He stumbled forward, bracing his hands against his knees, gasping for air as a cold sweat broke out across his forehead.

 

"Whoa there, young man!"

 

The voice boomed like a thunderclap, vibrating the very pavement beneath Izuku's feet.

 

Izuku forced his heavy eyes upward. Standing before him, blocking out the sun, was a mountain of muscle clad in a white t-shirt and cargo pants. He had two towering tufts of blonde hair standing straight up like rabbit ears.

 

Izuku’s hyper-analytical brain, despite the crash, instantly recognized the silhouette.

 

Height: 220 cm. Weight: 255 kg. Muscle mass: Maximum achievable human limit. Identity...

 

"A-All Might?" Izuku wheezed, his jaw dropping.

 

"FEAR NOT, CITIZEN! FOR I AM—oh, wait, you're already safe!" All Might bellowed, giving a hearty, booming laugh. He held up two large, two-liter plastic soda bottles, both of which were completely empty. "I was chasing a rather slippery villain through the sewers, but it seems he escaped into the daylight! Did you happen to see—"

 

Before All Might could finish, a wet, angry roar echoed from the tunnel. The Sludge Villain, missing half its mass and looking incredibly angry, surged toward the exit.

 

"THERE HE IS!" All Might shouted. He didn't even adopt a fighting stance. He simply pulled back his right arm. "TEXAS SMASH!"

 

All Might threw a punch at the empty air.

 

The sheer, unfathomable wind pressure generated by the strike hit the tunnel like a localized hurricane. Izuku, despite being ten meters away, had to cross his arms and dig his heels into the ground to avoid being blown away. The wind ripped through the tunnel, completely atomizing the Sludge Villain, scattering his liquid form into thousands of harmless droplets that rained down on the concrete.

 

All Might laughed again, moving with blinding speed to scoop up the scattered sludge and shove it into the two plastic soda bottles, capping them tightly.

 

"A job well done!" All Might declared, turning to Izuku. "Thank you for holding him off, young man! I apologize for the scare. I usually don't make mistakes like letting a villain slip away, but I'm in a new city and got lost in the sewer system!"

 

Izuku was starstruck. He was standing in front of the Symbol of Peace. The man whose videos he had watched ten thousand times.

 

He fumbled for his notebook. "A-All Might! Sir! C-could I please get an autograph?! You're my biggest hero! I've studied all your fight patterns, your kinetic energy transfer techniques, everything!"

 

All Might blinked, clearly amused by the boy's intense rambling. He took the notebook and signed it with a massive, flourishing marker pen he seemingly pulled from thin air.

 

"A studious fan! I love it!" All Might boomed, handing the notebook back. "Study hard, young man, and maybe one day you'll be a hero too! Now, I must be off to turn this villain into the police! STAY SAFE!"

 

All Might crouched down. The muscles in his legs expanded to terrifying proportions.

 

"Wait!" Izuku yelled, taking a step forward. He had so many questions. He wanted to ask All Might about physical conditioning, about how to handle the sheer recoil of massive muscular exertion.

 

But All Might was already gone. He leaped into the air with the force of a missile launch, disappearing into the clouds.

 

Izuku stood there, the wind ruffling his green hair. He looked down at the signature spanning across two full pages of his notebook. A genuine, massive smile broke across his face.

 

Then, his stomach gave a loud, painful rumble.

 

"Right. Carbohydrates," Izuku muttered to himself, his legs trembling slightly. He reached into his pouch and pulled out a "Green Chocolate"—a dense block of dark chocolate infused with peanut butter and oats. He took a large bite, forcing himself to chew slowly to let the fats and complex carbs stabilize his plummeting blood sugar.

 

He began the walk home, his mind buzzing with the encounter. He had met All Might. He had survived a villain attack. His Blue Gummy prototype was a success, though the crash was a bit sharper than he calculated.

 

He was so lost in his equations that he almost didn't notice the massive plume of black smoke rising over the city skyline, a few blocks away.

 

Boom!

 

A shockwave rattled the windows of the storefronts around him. Izuku looked up.

 

Explosions? he thought, chewing his chocolate faster. Wait. That smell...

 

The wind shifted, carrying the scent of burning buildings, but underneath it, sharp and unmistakable to Izuku's trained senses, was the smell of burnt sugar and ozone. Nitroglycerin sweat.

 

Kacchan.

 

Izuku broke into a run. His blood sugar was stabilizing, giving him back his normal, athletic human strength. He sprinted toward the smoke, his heart pounding in his chest.

 

He pushed his way through a massive crowd of onlookers gathered at the edge of a shopping district. The scene before him was absolute chaos.

 

Several buildings were on fire. The street was cratered and destroyed. Standing in the center of the devastation, towering over the wreckage, was the Sludge Villain.

 

But how? Izuku thought, his eyes widening in horror. All Might put him in those bottles!

 

He scanned the area. There, on the edge of the crowd, was All Might, but he was unrecognizable to the masses. He was a skeletal, emaciated version of himself, leaning against a lamppost, coughing violently, a look of utter despair on his sunken face. Izuku didn't know who this gaunt man was, but he recognized the baggy clothes.

 

He looked back at the villain. The sludge mass was twice as large as before. And thrashing wildly within the center of the dark green muck, trying desperately to pry the sludge away from his mouth and nose, was Katsuki Bakugo.

 

Bakugo was firing off massive explosions from his palms, but it was completely ineffective. The blasts just blew chunks of sludge away, which immediately reformed. The explosions were only serving to set the surrounding buildings on fire.

 

"It's no use!" yelled Death Arms, a pro hero with massive physical strength, as he was thrown back by a wave of sludge. "I can't grab him! It's like punching water!"

 

"My wood will just burn up in those explosions!" Kamui Woods shouted, shielding the crowd from the flames.

 

"I need a two-lane road to maneuver!" Mt. Lady complained, stuck in her giant form at the edge of the intersection. "I can't get in there!"

 

Izuku stared at the scene. His analytical mind, running purely on baseline human speed, rapidly processed the variables.

 

The heroes are incapacitated due to poor quirk matchups. The villain is fluid, rendering blunt force ineffective. The hostage is generating heat and concussive force, creating a hazard zone. Time until hostage succumbs to asphyxiation: Approximately sixty seconds.

 

Izuku looked at Bakugo's face.

 

Bakugo was arrogant. He was loud. He was abrasive.

 

But right now, his crimson eyes were wide with raw, unfiltered terror. He was looking at the crowd, pleading silently for someone, anyone, to save him.

 

The pro heroes were standing still, waiting for someone with a suitable Quirk to arrive.

 

Izuku's hand slowly drifted toward the utility belt hidden under his jacket. His fingers brushed against the zipper of the red pouch.

 

The Red Gummy, his brain warned him. Concentrated glucose, caffeine, synthesized adrenaline. Multiplier: 10x. Estimated burn time before catastrophic cellular failure: Three minutes. The crash will be agonizing. You are not physically mature enough to handle full output without risking muscle tearing.

 

"Don't do it, kid," a man next to him murmured, watching the fire. "There's nothing we can do. Just wait for the pros with water Quirks."

 

Izuku looked at the gaunt man leaning against the lamppost. The man who wore All Might's clothes. He was gripping his chest, looking on in agony, clearly unable to intervene.

 

A hero, Izuku thought, the words of All Might's countless interviews echoing in his head, is someone who shatters the obstacles in their path to save a life.

 

Izuku didn't think anymore.

 

He unzipped the red pouch. He pulled out the glowing, diamond-shaped Red Gummy.

 

He threw off his heavy yellow backpack.

 

And then, he popped the candy into his mouth, bit down hard, and broke into a dead sprint toward the inferno.

 

"Hey! Kid! Stop!" Death Arms roared, reaching out to grab him, but his hand closed on empty air.

 

0.1 seconds.

 

The lipid barrier of the candy dissolved instantly upon contact with his saliva. The hyper-concentrated concoction of sugar, caffeine, and adrenaline flooded his mucosal membranes. It bypassed digestion entirely, hitting his bloodstream like a freight train loaded with dynamite.

 

0.2 seconds.

 

Izuku's pupils dilated until his eyes were entirely black voids ringed by a thin sliver of glowing emerald. His heart rate skyrocketed from 100 to 220 beats per minute. The blood vessels in his neck and arms bulged, glowing faintly through his skin as his internal body temperature spiked to 40 degrees Celsius.

 

0.3 seconds.

 

The world ground to a screeching, absolute halt.

 

The roaring flames of the burning buildings froze in mid-flicker. The screaming of the crowd became a low, distorted, unidentifiable hum. The Sludge Villain's thrashing tentacles hung motionless in the air.

 

The Hyper-Metabolic State activated at maximum capacity.

 

System Overdrive, his hyper-accelerated brain noted calmly, a supercomputer observing a nuclear meltdown. Muscular fiber density increased by 1000%. Neurological conduction velocity at absolute peak. Pain receptors suppressed by adrenaline surge. Kinetic potential: Critical.

 

Izuku was no longer just a fourteen-year-old boy. He was a ballistic missile, a vessel containing a terrifying, unstable chemical reaction of pure, explosive energy.

 

He didn't run; he launched himself. Every step he took shattered the pavement beneath his sneakers, leaving small craters in the asphalt. The sheer wind pressure generated by his movement blew the flames of the burning buildings backward.

 

To the pro heroes and the crowd, Izuku was nothing more than a sudden, violent blur of green and black that tore across the intersection.

 

Target identified: Hostage, Katsuki Bakugo. Obstacle: Fluid medium. Blunt force ineffective. Solution: Hydrodynamic displacement via concussive shockwave.

 

Izuku arrived directly in front of the Sludge Villain. He planted his left foot down, the force cracking the street down to the sewer line. He drew back his right fist.

 

He didn't aim for the villain. He aimed for the space immediately adjacent to the sludge holding Bakugo.

 

Output: 100% available capacity. Execution.

 

Izuku threw the punch.

 

He didn't just strike the air; he obliterated it. The sheer kinetic force of his hyper-dense muscles violently displacing the oxygen created a massive, localized vacuum, followed instantly by a devastating shockwave.

 

CRAAAACK-BOOOOM!

 

The sound was deafening, like a bomb going off in the middle of the street.

 

The wind pressure didn't just blow the sludge away; it sheared it completely apart on a molecular level. The villain shrieked in agony as the sheer force of the air pressure ripped his liquid form into a fine mist, violently violently violently tearing him away from Bakugo.

 

Bakugo, suddenly freed, gasped violently for air, falling forward.

 

Objective 1 Complete. Objective 2: Secure Hostage.

 

Izuku moved faster than gravity. Before Bakugo could even begin to fall toward the pavement, Izuku caught him by the collar of his uniform.

 

Warning, his brain flashed, the cold logic piercing through the adrenaline high. Muscular integrity failing. Right bicep micro-tears detected. Glycogen reserves depleting at a critical rate. Time remaining before hypoglycemic crash: 15 seconds.

 

Fifteen seconds in normal time was an eternity in Hyper-Metabolic time, but Izuku knew he couldn't hold onto the power. The heat building up inside his body was becoming unbearable. He felt like his blood was boiling.

 

He dug his heels in, spinning on his axis, and with a grunt of immense effort, he hurled Bakugo through the air like a baseball, tossing him clear out of the danger zone and directly into the waiting arms of Death Arms.

 

"What the hell?!" Death Arms grunted, catching the sputtering Bakugo as he skidded backward from the sheer force of the throw.

 

Izuku turned back to the villain. The sludge was already beginning to reform, the eyes and teeth pulling the mist back together.

 

"YOU LITTLE BRAT!" the villain roared, towering over Izuku, a massive tidal wave of muck rising up to crush him. "I'LL DROWN YOU!"

 

Warning. Glycogen reserves depleted. System failure imminent.

 

The fog descended. The world snapped back to normal speed. The roaring flames, the screaming crowd, the deafening noise—it all rushed back into Izuku's senses like a physical blow.

 

The power shut off.

 

It was as if someone had pulled the plug on his internal reactor. The heat instantly vanished, replaced by an agonizing, freezing chill. His muscles, which had been dense as steel a microsecond ago, suddenly felt like wet paper.

 

He collapsed to his knees. A violent tremor wracked his entire body. He coughed, spitting a small amount of blood onto the pavement as his internal organs rebelled against the sudden drop in blood pressure.

 

Hypoglycemic shock, he thought, his vision blurring. He looked up at the towering wave of sludge about to crash down on him. I miscalculated the burn rate of the adrenaline mix. I'm empty.

 

He closed his eyes, bracing for impact.

 

But the impact never came.

 

"I REALLY AM PATHETIC."

 

The voice boomed with a familiar, world-shaking resonance.

 

Izuku opened his eyes. Standing over him, shielding his frail, shaking body, was a mountain of muscle.

 

All Might had returned. His massive form was steaming, a look of profound, furious determination on his face.

 

"I told you the traits that make a great champion," All Might roared, blood trickling from the corner of his wide, iconic smile, but his eyes blazing with undeniable power. "But I didn't live up to my own ideals! PROS ARE ALWAYS RISKING THEIR LIVES!"

 

All Might grabbed the wrist of the Sludge Villain's sweeping attack, entirely halting the momentum of the massive liquid beast.

 

"DETROIT..."

 

All Might pulled his right arm back. The muscles coiled tighter than spring steel.

 

Izuku watched, his vision swimming, his body shaking violently, but his mind still analyzing. The kinetic potential... it's astronomical. He's not using a multiplier. This is his base power.

 

"...SMASH!"

 

All Might drove his fist forward.

 

The shockwave from Izuku's punch had been like a bomb. The shockwave from All Might's punch was a natural disaster.

 

The air pressure didn't just obliterate the Sludge Villain; it changed the weather. The sheer force created a localized tornado that ripped through the street, completely atomizing the villain, extinguishing the fires on the buildings instantly, and sending a massive updraft into the sky.

 

The clouds above Musutafu parted, sheared apart by the sheer power of the punch. Sunlight poured down onto the ruined street.

 

It began to rain.

 

Izuku stared up at the sky, feeling the cold drops of water hit his feverish face. He looked at All Might, who stood victorious, steaming in the rain, the undisputed Symbol of Peace.

 

He's incredible, Izuku thought.

 

And then, his body finally gave out. The darkness rushed up to meet him, and he collapsed sideways onto the wet pavement, slipping into unconsciousness.

 

 

 

Beep... beep... beep...

 

"He's severely hypoglycemic. Get an IV line of glucose in him immediately. His core temperature is dangerously low."

 

"Understood. Heart rate is stabilizing, but he's got micro-tears in the muscle fibers of his right arm. What kind of Quirk does this to a kid?"

 

Izuku groaned, the harsh fluorescent lights of the ambulance cutting through his closed eyelids. The smell of antiseptic and ozone filled his nose. He felt a sharp prick in the back of his hand, followed by the blessedly cool sensation of liquid sugar entering his veins.

 

He cracked his eyes open. He was lying on a gurney in the back of an ambulance, the doors open to the street. A paramedic was checking his vitals.

 

"Hey, kid, take it easy," the paramedic said gently. "You took a hell of a dive there."

 

Izuku tried to sit up, his muscles screaming in protest. "Kacchan... Bakugo. Is he..."

 

"The explosive kid? He's fine," a gruff voice said.

 

Death Arms stepped into the back of the ambulance, crossing his massive arms. He looked down at Izuku with a mixture of stern disapproval and undeniable awe. Kamui Woods stood behind him.

 

"What you did was incredibly reckless, kid," Death Arms said sternly. "You charged into a hostage situation with no backup, no plan, and a Quirk that clearly destroys your own body. You could have been killed. You could have gotten the hostage killed."

 

Izuku looked down at his shaking hands. "I know. It was tactically unsound. But he was dying. You weren't doing anything."

 

Death Arms flinched slightly, the truth of the boy's words stinging. "We were assessing the situation. Waiting for the right Quirks. That's how professional hero work is done."

 

"No," a new voice interrupted.

 

Katsuki Bakugo pushed his way past the pro heroes. He was covered in soot, his uniform torn, but his red eyes were burning with an intensity Izuku hadn't seen since they were four years old in the sandbox.

 

The heroes parted slightly for the victim. Bakugo stood at the edge of the ambulance, glaring down at Izuku.

 

"I didn't ask for your help, you damn nerd," Bakugo ground out, his fists clenched at his sides.

 

"I know, Kacchan," Izuku replied weakly, leaning back against the pillows.

 

Bakugo stared at him, his jaw muscles working. He looked at the IV line pumping sugar into Izuku's arm, then at the sheer exhaustion written across Izuku's pale face.

 

"You moved fast," Bakugo said softly, almost reluctantly. "Faster than before. What was that? Ten times?"

 

"Yeah," Izuku whispered. "Red Gummy prototype."

 

Bakugo scoffed, turning around. "Well, your prototype sucks. It broke your arm. Fix it before the U.A. exams, Sugar-Freak. I won't accept a win if you die of a sugar crash halfway through the practical."

 

With that, Bakugo shoved his hands into his pockets and stalked away.

 

Izuku smiled faintly. Coming from Bakugo, that was a glowing endorsement.

 

After thirty minutes of the IV drip, Izuku's blood sugar had stabilized enough for the paramedics to release him. They bandaged his strained right arm, gave him a heavy lecture about Quirk safety, and handed him a massive bag of glucose tablets to take home.

 

The sun was setting by the time Izuku finally started walking home. His body ached with every step. The micro-tears in his bicep throbbed with a dull, burning pain. His mind felt sluggish, the heavy hangover of the Hyper-Metabolic State.

 

He unwrapped a Green Chocolate from his pouch and chewed it slowly, the complex carbs doing their best to rebuild his shattered glycogen stores.

 

I need a better delivery system, he muttered to himself, pulling out his notebook with his good hand. The oral absorption is fast, but the adrenaline spikes my heart rate too high, leading to premature burnout. If I could bypass the digestive system entirely and introduce the glucose directly into the bloodstream... maybe a localized dermal patch? Or an injection gauntlet?

 

"I AM HERE!"

 

Izuku yelped, nearly dropping his notebook as All Might suddenly slid out from a nearby alleyway, striking a heroic pose, his massive muscles flexing in the twilight.

 

"All Might?!" Izuku gasped, his heart leaping into his throat. "W-what are you doing here? How did you get away from the reporters?"

 

All Might let out a booming laugh. "HAHAHA! Escaping reporters is a piece of cake for a pro! I simply used a burst of speed to—bleeegh!"

 

Without warning, All Might deflated. A massive cloud of steam erupted from his body, and the mountain of muscle vanished, replaced by the gaunt, skeletal man Izuku had seen in the crowd. The man coughed violently, wiping a speck of blood from his chin.

 

Izuku stared, horrified. "Y-you! You're the guy from the crowd! But... you're All Might? What happened to you?!"

 

The gaunt man sighed, leaning against a brick wall. "Yes, young man. I am All Might. Or, what's left of him."

 

He pulled up his baggy white t-shirt, revealing his left side. Izuku gasped. The entire left side of All Might's torso was a mess of gnarled, twisted scar tissue. It looked like a massive chunk of his body had simply been obliterated.

 

"I got this in a fight five years ago," All Might explained, his voice quiet, devoid of the booming bravado. "My respiratory system was nearly destroyed. I lost my stomach entirely. I've had repeated surgeries, but I can only do hero work for about three hours a day now. The rest of the time, I look like this."

 

Izuku's analytical brain immediately began processing the medical nightmare before him. Loss of stomach? Compromised respiratory function? How does he generate that much kinetic output without a proper digestive system to process fuel? His basal metabolic rate must be sustained by something else. A stockpiling Quirk?

 

"I'm telling you this," All Might continued, looking Izuku directly in the eyes, "because I came here to thank you, and to correct a mistake."

 

Izuku blinked. "A mistake?"

 

"Back there, in the alley, and then again in the street," All Might said, stepping closer. "If you hadn't told me about the villain in the alley... if you hadn't rushed into that fire to save your friend... I would have just stood there. I was out of time. My body was failing. I was a pathetic excuse for a hero, watching a child die because I was afraid of pushing my limits."

 

All Might placed a large, bony hand on Izuku's shoulder.

 

"But you," All Might said, his blue eyes shining with profound respect. "You didn't hesitate. You knew your Quirk would tear your body apart, and you still threw yourself into the fire. Of all the pro heroes there, it was you—a timid, Quirk-damaged middle schooler—who acted. You spurred me to action."

 

Tears pricked at the corners of Izuku's eyes. The greatest hero in the world was thanking him.

 

"Your Quirk, young man," All Might said softly. "I saw it. I saw the power. For a fraction of a second, when you hit that wind pressure... you generated force that rivaled my own. What is the nature of your power?"

 

Izuku wiped his eyes, his scientific mind taking over. "It's a metabolic mutation. I process simple carbohydrates—sugar—into raw kinetic energy and neurological acceleration. It's a multiplier effect. The candy I ate gave me roughly ten times my normal physical output, and hyper-accelerated my brain."

 

All Might's eyes widened slightly. "A multiplier? That is... incredibly potent. But I saw the aftermath. You collapsed. You were shaking."

 

"The crash," Izuku nodded, looking down at his bandaged arm. "My body burns the fuel instantly. When it's gone, I go into severe hypoglycemic shock. If I push the multiplier too high, my muscles tear themselves apart because they can't handle the strain of the force I'm generating."

 

All Might looked at the boy, a deep, thoughtful silence falling between them.

 

Originally, All Might had come here with a different intention. He had seen the spirit of a true hero in this boy. He had seen the self-sacrifice. He had considered, for a brief moment, offering this boy his own Quirk—One For All.

 

But listening to the boy explain his physiology, All Might realized that would be a death sentence.

 

One For All was an unfathomable stockpile of raw power. If he gave it to a boy whose body already functioned like a runaway nuclear reactor, a boy whose muscles tore under the strain of his own Quirk... the sheer influx of One For All wouldn't just break his limbs. It would blow him apart. The boy didn't need a power-stockpiling Quirk. He already had the power of a top-tier pro hero locked inside his metabolic system.

 

What the boy needed was control. What the boy needed was a vessel strong enough to contain the explosion.

 

"Young Midoriya," All Might said, his voice dropping into a serious, commanding tone. "You have the spirit of a true hero. And you possess a Quirk of terrifying, magnificent potential."

 

Izuku looked up, his heart pounding.

 

"But you fight like a brawler using a bomb," All Might continued critically. "You rely entirely on the raw, explosive output of your power. You throw a punch and let the shockwave do the work, sacrificing your own body in the recoil. If you continue down this path, you will destroy yourself before you ever reach the top."

 

Izuku swallowed hard. He knew it was true. The math didn't lie. His body was the weak link in the equation.

 

"You need to become stronger," All Might said, raising a fist. "Not just through chemical enhancements, but through true, fundamental physical conditioning and technique. You need to learn how to channel that explosive energy, how to direct it through martial arts, how to move without tearing your muscles."

 

All Might pointed directly at Izuku's chest.

 

"I cannot give you my power, young Midoriya, because you do not need it. But I can give you my knowledge. The U.A. entrance exam is ten months away." All Might smiled, a fierce, challenging grin. "What do you say, young man? Will you let me teach you how to fight?"

 

Izuku stood frozen on the sidewalk.

 

He didn't need a supercomputer brain to analyze this. He didn't need to calculate the probabilities.

 

He was being offered personal mentorship by the Symbol of Peace. The man who had mastered the art of kinetic force.

 

Izuku dropped his backpack. He bowed so low his head nearly touched his knees, tears streaming freely down his face.

 

"Yes!" Izuku cried, his voice thick with emotion. "Please, All Might! Teach me everything!"

 

All Might laughed, the sound warm and genuine in the quiet street. "Excellent! Meet me at the Dagobah Municipal Beach tomorrow at 6:00 AM sharp! Bring your running shoes, and tell your dietician you're going to need a lot more protein!"

 

Izuku lifted his head, wiping his tears, his green eyes burning with a new, unstoppable fire.

 

He had the brain. He had the fuel.

 

And now, he had the teacher.

 

The confectionary hero was going to change the world.

 

 

The human body is a machine. It requires fuel, oxygen, and rest. For a normal human, pushing that machine to its absolute limits takes years of rigorous training, conditioning the muscles, and callousing the mind.

 

For Izuku Midoriya, the machine didn't just need conditioning; it needed to be rebuilt from the ground up to withstand the force of a localized nuclear meltdown.

 

Ten months. That was all the time he had been given. Ten months under the grueling, merciless, and utterly brilliant tutelage of All Might. The Dagobah Municipal Beach Park, once a towering landfill of rusted refrigerators, crushed cars, and heavy appliances, now gleamed as a pristine stretch of white sand against the morning tide.

 

Izuku had cleared it. Not by popping a Red Gummy and hurling the trash into the ocean in a three-minute frenzy—All Might had strictly forbidden the use of his Quirk for the cleanup. "If you rely on your engine to carry the chassis," All Might had lectured, "the moment you hit a bump, the chassis will shatter. You must build the frame first!"

 

So, Izuku lifted. He dragged. He pulled. He ate thousands upon thousands of calories of lean protein and complex carbohydrates, carefully calculated by his dietician and cross-referenced by All Might’s own bizarre, golden-age training manuals. He learned martial arts. He learned how to throw a punch so that the kinetic force traveled up from the ball of his foot, through his hips, and out his fist, rather than just swinging from the shoulder. He learned how to fall, how to roll, how to absorb impact.

 

By the morning of February 26th, the day of the U.A. Entrance Exam, Izuku Midoriya looked into his bathroom mirror and barely recognized the boy staring back.

 

He was still lean—his high basal metabolic rate made it nearly impossible for him to bulk up like All Might—but the softness of his youth had been entirely burned away. Beneath his skin lay dense, tightly coiled cords of muscle, resembling the physique of an Olympic gymnast. His green eyes, sharp and clear, held a quiet, calculating intensity.

 

"Izuku! Breakfast is ready! You need to eat!" Inko’s voice called from the kitchen, laced with a familiar, high-strung anxiety.

 

"Coming, Mom!" Izuku replied.

 

He turned away from the mirror and picked up his most prized possession, laying out neatly on his bed: his tactical utility belt.

 

Mei Hatsume, a girl he had met entirely by chance at a specialized support item convention a few months prior, had taken his rudimentary canvas belt and turned it into a masterpiece of engineering. It was sleek, made of high-tensile, fire-resistant polymer, and secured tightly around his waist and thighs to prevent shifting during high-speed maneuvers.

 

Along the belt were rows of specialized, color-coded, hermetically sealed dispensers.

 

Blue: The Speed Gummies. High caffeine, pure glucose, fast-acting vasodilators. Designed to push his neurological firing rate and reflex time to the absolute maximum. Multiplier: 5x Speed, 2x Strength. Burn time: 4 minutes.

Red: The Strength Gummies. Synthesized adrenaline, dense maltodextrin. Designed for raw, explosive muscular hypertrophy. Multiplier: 10x Strength, 3x Speed. Burn time: 2.5 minutes.

Green: The Endurance Chocolates. Complex carbs, fats, oat-base. Used to stave off the hypoglycemic crash and provide a sustained, baseline 2x boost across the board for roughly twenty minutes.

Yellow: The Mind Candies. Pure, slow-dissolving sucrose hard candies. No physical boost, entirely dedicated to maintaining the hyper-cognitive state for written exams and tactical analysis.

 

And then, hidden in a secure, biometric-locked pouch at the very back of the belt, sat a single, oversized sphere wrapped in thick, black foil.

 

The Jawbreaker.

 

Izuku stared at the black pouch for a long moment. His heart gave a preemptive, nervous flutter. The Jawbreaker was the culmination of his most dangerous chemical theories. It was an ultra-dense, multi-layered jawbreaker laced with a terrifying cocktail of pure liquid glucose, epinephrine, and a dangerous amount of synthesized cortisol to completely shut down his body's pain receptors.

 

Theoretical Multiplier: 30x.

Estimated Burn Time: 45 seconds.

Drawback: Guaranteed severe hypoglycemic shock, high probability of muscle tearing, bone fractures from kinetic recoil, and potential localized paralysis.

 

It was a suicide pill. A last resort. He prayed to every hero in the heavens that he wouldn't need it today.

 

He snapped the belt around his waist, threw on his middle school uniform jacket to conceal it, and walked out into the kitchen. He quickly consumed the massive breakfast Inko had prepared—brown rice, grilled salmon, four eggs, and a large bowl of oatmeal—kissed his weeping mother on the cheek, and headed out the door.

 

 

 

U.A. High School was a fortress. The massive, H-shaped glass buildings gleamed in the morning sun, surrounded by impenetrable walls and towering security gates.

 

Izuku stood at the entrance, his yellow backpack slung over one shoulder, taking a deep, centering breath.

 

"Out of my way, Deku."

 

The voice was a low, aggressive growl. Izuku didn't even need to turn around to know who it was. Katsuki Bakugo strode past him, his hands shoved deep into his pockets, his posture radiating an aura of violent confidence.

 

"Morning, Kacchan," Izuku said mildly, falling into step beside him.

 

Bakugo shot him a sideways glare. "Don't walk next to me. I don't want the stench of your nerd-sweat rubbing off on me before I destroy this exam."

 

"Statistically speaking, walking together reduces the overall air resistance, allowing us to conserve approximately point-two percent of our kinetic energy before the practical," Izuku noted, his brain automatically crunching the numbers.

 

Bakugo's eye twitched. "I will literally blow your face off right here."

 

"Good luck to you too, Kacchan," Izuku smiled, pausing to adjust his shoe. Bakugo scoffed and kept walking, storming ahead into the massive courtyard.

 

Izuku took another step, but his mind, heavily focused on running final mental calculations regarding his blood sugar levels, failed to register the uneven paving stone right in front of his foot.

 

His toe caught the edge. His center of gravity pitched forward.

 

Trajectory: Downward. Impact in: 0.8 seconds. Optimal reaction: Tense shoulder muscles, roll to distribute kinetic shock...

 

Before Izuku could execute the roll, the sensation of gravity entirely vanished.

 

He was suspended in mid-air, floating helplessly about three inches off the ground, his arms flailing slightly.

 

"Are you okay?"

 

A bright, bubbly voice broke through his momentary confusion. Izuku turned his head. Standing next to him was a girl with short, bobbed brown hair, permanent rosy cheeks, and large, warm brown eyes. She had one hand raised, her fingertips pressed together, and she was smiling brightly.

 

"I stopped you with my Quirk," she said cheerfully, bringing her hands together. "I'm sorry I didn't ask first, but I figured you wouldn't mind me catching you! It would be bad luck to fall on the very first day, right?"

 

Izuku blinked. Anti-gravity? Or localized mass manipulation? His mind raced. Fascinating. If she touches an object, does she negate the gravitational pull of the Earth, or does she alter the density of the object itself?

 

"Uh... y-yes! Thank you!" Izuku stammered, suddenly very aware of how close she was. For all his intense tactical training, talking to a cute girl was still entirely outside his operational parameters.

 

"I'm Ochaco Uraraka!" she beamed as Izuku's feet touched the ground. "Are you nervous? I'm super nervous. The practical exam is supposed to be really tough. Good luck!"

 

She waved and trotted off toward the entrance doors. Izuku stood there, his face slightly flushed, gripping the straps of his backpack.

 

Focus, Midoriya, he scolded himself, slapping his own cheeks lightly. You're not here to make friends. You're here to prove you belong.

 

The first hurdle was the written exam.

 

Izuku found his assigned seat in the massive lecture hall. As the proctor handed out the thick, daunting packets of paper, Izuku reached into his belt and popped a Yellow Candy into his mouth.

 

The change was entirely internal. His heart rate didn't spike, his muscles didn't bulge. But a profound, crystalline clarity washed over his mind. The ambient noise of pencils scratching and students nervously shuffling vanished. He opened the booklet.

 

The questions—complex calculus, obscure hero law statutes, situational ethics—might as well have been written in giant, glowing neon letters. His hyper-metabolic brain processed the text at an impossible speed. He didn't just read the questions; he absorbed them, referenced them against the encyclopedia of knowledge stored in his memory, and synthesized the answers perfectly.

 

He finished the three-hour exam in forty-two minutes. He spent the remaining time running mental simulations of hand-to-hand combat against various robotic constructs based on leaked U.A. patents he had found on the dark web.

 

Next was the Orientation.

 

The students were herded into a colossal auditorium. Izuku sat quietly, noting that Bakugo was a few seats down. The lights dimmed, and the Voice Hero, Present Mic, exploded onto the stage with his trademark deafening volume.

 

"WELCOME TO MY LIVE SHOW, EVERYBODY! EVERYBODY SAY 'HEY'!"

 

Silence echoed through the hall.

 

Izuku's brain, still slightly accelerated from the remnants of the Yellow Candy, immediately began dissecting the presentation. Present Mic projected a hologram explaining the rules: three types of villain robots worth one, two, and three points respectively, scattered across massive mock cities.

 

Destroy robots. Accrue points. A simple attritional point system, Izuku thought, his eyes narrowing. But that's too simple. U.A. prides itself on evaluating true heroic potential. A pure point-and-shoot game favors destructive Quirks heavily, like Kacchan's, but disadvantages rescue or support Quirks. There must be a hidden metric. Rescue points? Teamwork evaluations?

 

"Excuse me, sir!"

 

A tall, broad-shouldered boy with glasses and meticulously parted blue hair stood up abruptly, pointing rigidly at the stage. "I have a question! On the printout, there are four types of villains! If this is a misprint, U.A., the top hero agency in Japan, should be ashamed of this foolish mistake! We examinees are here in this place because we wish to be molded into exemplary heroes!"

 

The boy then turned, his hand chopping through the air to point directly at Izuku. "In addition, you over there with the curly hair!"

 

Izuku blinked, pointing to himself.

 

"You've been muttering this entire time! It's distracting! If you are here on a pleasure trip, then you should leave immediately!"

 

The auditorium snickered.

 

Izuku didn't blush. He didn't cower. The Yellow Candy’s hyper-logical state was still very much in control. He stood up slowly, matching the boy's intense gaze.

 

"I apologize if my audible processing disturbed you," Izuku said, his voice carrying perfectly across the silent hall. "However, I was merely calculating the structural integrity of the robotic models shown on the hologram and theorizing the existence of a secondary, unlisted grading metric based on U.A.'s historical acceptance patterns. If you find auditory analysis distracting in a controlled environment, you may struggle in a live battlefield where ambient noise regularly exceeds 120 decibels. But I will keep my voice down."

 

He sat back down. The auditorium was dead silent.

 

The blue-haired boy stared at Izuku, his mouth slightly open, completely utterly derailed by the hyper-logical, flawlessly delivered rebuttal. He bowed stiffly. "I... see. I apologize for the interruption!"

 

Present Mic cleared his throat, clearly amused. "ALRIGHT, ALRIGHT! Settle down, Examinee 7111. The curly-haired listener brings up a good point about analysis! And to answer your question about the fourth robot—it's the Zero Pointer! It's an obstacle, a massive gimmick that rampages in tight spaces. You get zero points for destroying it, so the smart move is to run away!"

 

An obstacle, Izuku noted. A test of threat assessment and situational awareness. Noted.

 

 

 

The students were bused out to the testing grounds. Izuku was assigned to Battle Center B. He stood before the towering, incredibly massive metal gates of the mock city, doing a series of light stretches.

 

He looked around. Bakugo wasn't here; U.A. deliberately separated students from the same middle school. But he did spot the blue-haired boy (who seemed to have engines in his calves) and, to his pleasant surprise, the anti-gravity girl, Uraraka.

 

Uraraka looked pale, taking deep breaths. Izuku took a step toward her, intending to offer a few words of tactical advice to calm her down, but a heavy hand clamped onto his shoulder.

 

It was the blue-haired boy. "She is trying to focus. Are you intending to disrupt her concentration again, as you disrupted the presentation?"

 

Izuku looked at the hand on his shoulder, then up at the boy. "No. I was intending to remind her that deep breathing without a rhythmic cadence can actually trigger hyperventilation and increase cortisol levels, which impairs Quirk activation. But thank you for your concern, Examinee 7111."

 

The boy stiffened, pulling his hand back as if he had been burned. "I... am Tenya Iida. And you are?"

 

"Izuku Midoriya."

 

"RIGHT, LISTENERS!" Present Mic's voice blasted from speakers mounted on the walls. "START YOUR ENGINES!"

 

Izuku's hand blurred. He unzipped the green pouch and the blue pouch simultaneously. He popped a Green Chocolate and a Blue Gummy into his mouth.

 

Combination protocol initiated. Green Chocolate for sustained glycogen base to prevent catastrophic crash. Blue Gummy for immediate neurological and fast-twitch muscle activation. Total Multiplier: 5x Speed, 4x Strength. Estimated safe burn time: 8 minutes.

 

He bit down.

 

The gate hadn't even fully opened when the rush hit him.

 

The world slowed to a crawl. The nervous muttering of the students around him stretched into deep, unintelligible groans. His heart hammered in his chest—a steady, powerful war drum pumping hyper-oxygenated blood to his dense muscles. His pupils dilated, the emerald irises glowing with a terrifying, predatory focus.

 

"GO! GO! GO! THERE ARE NO COUNTDOWNS IN REAL BATTLES!" Present Mic screamed.

 

The other students hesitated, confused by the lack of a formal start.

 

Izuku didn't.

 

He vanished.

 

To Iida and Uraraka, Izuku was there one second, and the next, there was only a loud CRACK of displaced air, a crater in the pavement where he had been standing, and a gust of wind that ruffled their hair.

 

Izuku was already fifty meters inside the city.

 

He ran down the center of the main avenue, his legs moving with the precision and power of pneumatic pistons. His hyper-analytical brain mapped the city grid instantly.

 

Target acquired. One-Pointer. Ten o'clock. Distance: 30 meters. Threat level: Negligible.

 

A green, single-wheeled robot rolled out from an alleyway, its red targeting sensors locking onto Izuku. "TARGET ACQUIRED."

 

It raised its mechanical arms to fire a net.

 

Izuku didn't slow down. He accelerated. At a 5x speed multiplier, he was crossing thirty meters in less than a second.

 

He didn't throw a massive, wind-pressure punch. That wasted energy. He needed efficiency. He slid low beneath the robot's targeting laser, driving the palm of his hand upward in a perfect, martial-arts-form uppercut directly into the robot's central chassis seam.

 

The combination of his forward momentum and his 4x strength multiplier struck the metal with the force of a wrecking ball. The robot didn't just break; it ruptured. The chassis caved inward, internal circuitry sparking wildly, and the machine was lifted entirely off the ground before crashing backward, dead.

 

One point. Time elapsed: 4 seconds.

 

Izuku didn't stop. He pushed off the fallen robot, launching himself onto the fire escape of an adjacent building. He bounded up the metal stairs in two leaps, reaching the roof to gain a tactical vantage point.

 

From the roof, the mock city was a chessboard. He could see the robots spawning. He could see the other students rushing in, engaging in messy, inefficient brawls.

 

Three-Pointer. Heavy armor. Caterpillar treads. Missile launchers. Location: Main intersection. Engaging now.

 

Izuku leaped off the four-story building.

 

For a normal human, the fall would shatter their legs. For Izuku, his brain instantly calculated his terminal velocity and the necessary muscle tension to absorb the kinetic shock. He landed directly on the roof of the Three-Pointer with a heavy CLANG.

 

The robot's sensors whirred, trying to aim its weapons upward, but it was too slow.

 

Izuku drew his right fist back. He aimed specifically for the sensor array on the robot's head—the weakest point in the armor.

 

"Armor-piercing strike," Izuku muttered, his voice a distorted, fast-paced hum. He drove his fist down.

 

His knuckles punched clean through the thick steel plating as if it were wet cardboard. He grabbed a handful of critical wiring and violently ripped it out. The robot shuddered, its optical sensors dying, and ground to a halt.

 

Four points. Time elapsed: 18 seconds.

 

Izuku was a ghost in the machine. He moved through the city with terrifying, surgical precision. He didn't fight the robots; he dismantled them. He used his hyper-cognition to predict their attack patterns before they even fired. If a Two-Pointer shot a foam missile at him, he didn't dodge; he caught the missile by the fin and threw it back with triple the velocity, snapping the robot's neck joint.

 

In the observation room hidden deep within U.A., a group of pro heroes watched the monitors in stunned silence.

 

"Good lord," Midnight whispered, leaning closer to the screens. "Look at Examinee Midoriya in Battle Center B. His movements... there's zero wasted energy. He's not using a flashy, destructive Quirk. He's just... perfect."

 

"His Quirk registry says 'Hyper-Metabolism'," Snipe noted, adjusting his mask. "Strength and speed enhancement based on sugar consumption. But this isn't just brawn. His tactical processing speed is off the charts. He's dismantling those machines like a master mechanic."

 

In the back of the dark room, a skeletal man in a yellow suit gripped his knees, a massive, proud smile stretching across his gaunt face. Show them, my boy, All Might thought. Show them what a true hero looks like.

 

"He's racked up forty-five points in less than four minutes," a voice mumbled from the corner. Eraserhead stared at the screen, his dark eyes tracking Izuku's green blur. "Rational. Efficient. But relying on a consumable resource is a crutch. Let's see how he handles true adversity."

 

A hand slammed down on a large red button.

 

Back in Battle Center B, Izuku had just crushed the core of a Two-Pointer with a sweeping kick, bringing his total to fifty-one points.

 

Warning, his internal system flashed. Blue Gummy efficacy dropping. Glucose levels falling. Lactic acid buildup in leg muscles. Recommend immediate carbohydrate intake.

 

Izuku reached for his belt, pulling out a second Green Chocolate to maintain his baseline. He popped it into his mouth.

 

Suddenly, the ground beneath his feet violently shuddered.

 

It wasn't a small tremor. It felt like an earthquake. The asphalt of the street began to crack and buckle.

 

Izuku turned his head, his hyper-accelerated perception taking in the horrific sight.

 

At the end of the avenue, the buildings were literally being pushed aside. A colossal, towering shadow eclipsed the sun.

 

It was the Zero Pointer.

 

It wasn't just a robot; it was a walking skyscraper. Its treads were the size of buses. Its arms were massive steel girders. As it moved forward, it effortlessly crushed a four-story building beneath its treads, sending a massive shockwave of dust, concrete, and shattered glass hurtling down the street.

 

The other examinees broke.

 

"RUN!" someone screamed. "It's the Zero Pointer! It's huge!"

 

"Are they crazy?! We can't fight that!"

 

Students began sprinting past Izuku in a terrified stampede, abandoning their fights to escape the mechanical titan's path.

 

Izuku stood his ground. The dust washed over him. His brain immediately went to work.

 

Threat Assessment: Zero Pointer. Estimated height: 100 meters. Estimated weight: Incalculable. Armor: Impervious to current kinetic output. Weaknesses: Joint exposure minimal, central power core heavily shielded.

 

Tactical Conclusion: Unbeatable. Retreat is the only statistically viable option. Zero points awarded for engagement. Run.

 

Logic dictated retreat. Izuku turned to follow the other students.

 

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

 

The voice was faint, entirely drowned out to normal human ears by the grinding of the colossal treads and the screaming of the examinees. But Izuku’s auditory reception, operating at a 5x multiplier, caught it instantly.

 

He whipped his head around.

 

Sixty meters away, directly in the path of the advancing Zero Pointer, was Uraraka. She was trapped under a massive slab of concrete that had fallen from a crushed building. Her face was contorted in pain, her anti-gravity Quirk useless against the sheer weight pinning her leg.

 

The Zero Pointer's colossal tread was descending. She had maybe ten seconds before she was crushed to death.

 

Izuku's brain calculated the probabilities.

 

Distance: 60 meters. Time to impact: 10 seconds. Object weight pinning the target: Approx 3000 kilograms. Current Multiplier: 5x Speed, 4x Strength. Maximum lifting capacity at current output: 1500 kilograms.

 

Conclusion: Current output insufficient. I cannot lift the debris. I cannot move her in time. If I engage the Zero Pointer to halt its momentum, my current kinetic output will fail to breach its armor. I will be crushed along with her.

 

The math was absolute. The logic was flawless. There was no way to save her with his current power.

 

Izuku's hand moved on its own.

 

It bypassed the blue pouch. It bypassed the red pouch.

 

His fingers slid to the back of his belt, pressing the biometric lock. The black pouch clicked open.

 

Warning! his hyper-logical brain screamed at him. The Jawbreaker is untested. A 30x multiplier will cause catastrophic system failure. The recoil of the kinetic output will shatter your skeletal structure. The ensuing hypoglycemic crash may result in cardiac arrest. DO NOT CONSUME.

 

Izuku pulled the massive, black-foil-wrapped Jawbreaker from the pouch.

 

A hero, Izuku thought, his emerald eyes locking onto Uraraka's terrified face, is someone who shatters the logic that says they can't.

 

He ripped off the foil. He shoved the massive candy into his mouth.

 

He didn't wait for it to dissolve. He bit down with all his jaw strength, cracking the dense sugar sphere.

 

The liquid center—pure, unadulterated glucose, epinephrine, and pain-suppressing cortisol—exploded down his throat.

 

0.01 seconds.

 

The world didn't just slow down. It died.

 

Time entirely ceased to exist. A piece of falling debris hanging in the air next to Izuku stopped dead. The dust particles hung perfectly suspended. The deafening roar of the robot was silenced, leaving only the sound of a high-pitched, agonizing whine echoing in Izuku's skull.

 

SYSTEM OVERLOAD.

 

The heat wasn't a fire. It was a supernova. Izuku's blood literally began to boil. His skin flushed a deep, terrifying crimson. The veins in his neck, arms, and legs bulged against his skin, glowing with a bright, toxic-green light. His muscles didn't just harden; they expanded, tearing micro-fibers as they forcibly compressed into a density that defied human biology.

 

The pain was unimaginable—a tearing, burning agony that ripped through every nerve ending. But a split second later, the cortisol hit his brain, entirely severing his pain receptors. He felt nothing. He was a god of pure, unadulterated kinetic energy.

 

Multiplier: 30x.

 

Izuku looked up at the Zero Pointer.

 

He crouched down, placing his hands on the asphalt.

 

He didn't jump. He detonated.

 

The street beneath him exploded. A crater ten meters wide and three meters deep was carved into the earth instantly. The shockwave of his launch blew the surrounding examinees off their feet, hurling them backward.

 

Izuku shot into the air like a railgun projectile. The G-force was so intense his skin pulled back from his face. He broke the sound barrier instantly, a massive white cone of condensed air forming around his body.

 

In the observation room, the pro heroes leaped from their seats.

 

"What the hell is that?!" Present Mic yelled, pointing at the monitor where a green streak of light was rocketing up the side of the Zero Pointer.

 

"His power output just spiked by a thousand percent!" a technician screamed.

 

Izuku ascended a hundred meters in less than a second. He was eye-level with the Zero Pointer's massive, featureless face.

 

He pulled back his right arm.

 

Warning. Skeletal integrity of right arm insufficient to handle 30x kinetic transfer. Execution will result in severe comminuted fractures.

 

Izuku's eyes, entirely black and glowing with emerald fire, glared at the machine.

 

Detroit... he thought, echoing his master.

 

He drove his fist forward.

 

...SMASH!

 

The impact didn't make a sound. It was too loud for human ears to process.

 

When Izuku's fist struck the solid steel armor of the Zero Pointer's face, the armor didn't dent. It atomized.

 

The sheer, unfathomable transfer of kinetic energy bypassed the surface plating and shot directly into the core of the machine. The air pressure shockwave generated by the punch blasted outward in a massive, visible ring in the sky, blowing the clouds away and shattering the glass of every building in the mock city.

 

The colossal head of the Zero Pointer imploded inward. The massive gears, pistons, and nuclear batteries within the chassis were crushed into scrap metal instantly. The shockwave rippled down the length of the titan's body, blowing out its back paneling in a shower of sparks and flaming shrapnel.

 

The titan groaned, a deep, metallic death rattle, and began to fall backward, away from Uraraka.

 

In the air, suspended a hundred meters above the ground, Izuku's hyper-metabolic state immediately recognized the victory.

 

And then, the bill came due.

 

Fuel depleted. Hypoglycemic shock imminent. Structural integrity compromised.

 

Izuku heard a sickening, wet CRUNCH.

 

He looked at his right arm. From the elbow down, it was a mangled, purple ruin. The sheer recoil of hitting solid steel with the force of a meteor had shattered his radius and ulna into dozens of pieces. His fingers flopped uselessly.

 

But the broken arm was the least of his worries.

 

The 30x multiplier shut off abruptly.

 

The pain suppressors vanished.

 

Agony, pure and blinding, ripped through Izuku's consciousness. His heart, which had been beating at 300 beats per minute, stuttered violently. The supernova of heat in his veins turned into the freezing void of deep space.

 

Gravity reasserted its dominance.

 

Izuku began to fall.

 

He was a hundred meters in the air. He had a shattered arm, both of his legs were entirely paralyzed from the muscular burnout, and he was entering severe hypothermic shock from the total lack of blood sugar.

 

I'm going to die, he thought clearly. The hyper-cognition was gone, replaced by the sluggish, terrified thoughts of a normal, broken boy. I saved her... but I can't save myself.

 

He closed his eyes, the wind roaring in his ears as the ground rushed up to meet him.

 

Slap.

 

A soft, warm hand struck him squarely across the face.

 

Izuku's eyes snapped open.

 

Uraraka was hovering beside him in mid-air. She had somehow managed to crawl out from under the debris using the distraction of the robot falling, climbed onto a piece of floating rubble, and propelled herself upward.

 

Her face was strained, incredibly pale, and she looked horribly nauseous. But she had managed to touch his cheek.

 

"Release!" she gasped, pressing her fingertips together.

 

Izuku's body stopped falling instantly, losing all mass. He hung suspended in the air about two meters above the pavement. Uraraka plummeted past him, hitting the ground with a painful thud, rolling to absorb the impact before violently throwing up on the pavement.

 

Izuku slowly drifted down to the ground, bouncing lightly like a balloon.

 

He couldn't move. He lay flat on his back. His body was convulsing violently, his teeth chattering so hard they threatened to chip. The world was fading in and out, dark spots dancing across his vision.

 

Through the haze, he heard a loud buzzer.

 

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

 

Footsteps approached. The examinees who had run away were slowly creeping back, staring at Izuku in absolute, unfiltered terror and awe.

 

"He destroyed it..." one boy muttered. "He destroyed the Zero Pointer with one punch."

 

"Is he a monster? What kind of Quirk is that?"

 

"Never mind that, look at him! He's having a seizure!"

 

Izuku couldn't speak. He couldn't reach for his belt. The green pouch holding the emergency carbs was only inches from his good hand, but the neurological pathway between his brain and his fingers was completely shut down by the hypoglycemic shock.

 

Cold, he thought. So cold.

 

"Out of the way, you rubberneckers!" a sharp, commanding voice barked.

 

The crowd parted. A tiny, elderly woman wearing a lab coat and a visor hobbled forward, using a giant syringe as a walking cane. It was the Youthful Heroine, Recovery Girl.

 

She took one look at Izuku, her eyes narrowing behind her visor.

 

"Hypovolemic and hypoglycemic shock, massive muscular trauma, severe bone fractures," she rattled off, entirely unfazed. She reached into her pocket, pulling out a handful of gummy bears, and shoved them unceremoniously into Izuku's mouth.

 

"Chew, boy. If you can't chew, let them dissolve," she ordered.

 

Izuku couldn't chew, but the saliva in his mouth began to break down the sugar. A tiny, microscopic sliver of warmth entered his freezing body.

 

Recovery Girl leaned over and kissed his forehead.

 

Her Quirk, Heal, activated. It accelerated the natural healing process of the human body, using the patient's own stamina as fuel.

 

Izuku screamed. It was a raw, guttural sound of agony.

 

His bones forcibly snapped back into place, grinding against each other as the micro-fractures sealed. The torn muscle fibers knit themselves back together with brutal speed.

 

Because Recovery Girl's Quirk used the patient's stamina, and Izuku had virtually zero stamina left, the healing process drew from the absolute bottom of his reserves, leaving him feeling like a hollowed-out husk.

 

He lay panting on the ground, his arm intact but fiercely aching, completely unable to lift his head.

 

"You foolish, foolish boy," Recovery Girl scolded, though her voice carried a trace of profound sympathy. She tapped his chest lightly with her syringe. "Your Quirk... it's a chemical bomb. You pushed your internal organs to the absolute brink of failure. If this girl hadn't caught you, or if I hadn't been here, your heart would have stopped from the shock."

 

She stood up, looking down at him. "Power is meaningless if the vessel shatters when you use it. You need to learn restraint, or you won't live to see graduation."

 

Izuku closed his eyes, a single tear leaking from the corner.
