What if deku and Bakugo were twins with the same explosion quirk

 

The Bakugo household was never what one would call a quiet environment.

 

To live in the Bakugo residence was to live in the epicenter of a perpetual, loving, and immensely loud storm. Mitsuki Bakugo possessed a personality as volatile as her glycerin-secreting skin, and her husband, Masaru, though mild-mannered and soft-spoken, possessed acidic sweat that could spark when rubbed together. It was a genetic recipe for combustion.

 

But even Mitsuki and Masaru could not have predicted the sheer magnitude of the tempest they would unleash upon the world when they welcomed twins.

 

Katsuki and Izuku were born seven minutes apart. Katsuki was first, kicking and screaming with a set of lungs that rattled the hospital windows. Izuku followed, much quieter at first, observing the sterile lights with wide, viridian eyes before letting out a sharp, demanding cry of his own. Fraternal twins. They shared the same untamable ash-blonde hair, though Izuku’s was tinged with a faint, forest-green hue inherited from a distant grandparent. They shared the same sharp features, though Izuku’s eyes were large, round, and endlessly curious, while Katsuki’s were narrow, crimson, and fiercely determined.

 

From the moment they could walk, they were a matched set. A binary star system orbiting around a singular, defining obsession: Heroes. Specifically, the Number One Hero, All Might.

 

In the world of superhuman society, eighty percent of the population possessed a unique genetic trait called a Quirk. For the Bakugo twins, the waiting game for their Quirks was the most excruciating period of their short, four-year-old lives.

 

The manifestation began on a Tuesday in early spring.

 

The twins were at the local daycare, engaged in a heated debate over which of All Might’s signature moves was the most devastating. Katsuki argued for the raw power of the Texas Smash, while Izuku passionately defended the tactical superiority of the Carolina Smash.

 

"You’re just not thinking about the follow-through, Kacchan!" Izuku, four years old and armed with a plastic All Might action figure, pointed accusatorily at his brother. "The cross-chop hits two points of the villain's neck at once! It’s scientifically better!"

 

"Who cares about science when you can just blow the villain away with one punch?!" Katsuki retorted, his face flushing red with exertion. He balled his small hands into fists, slamming them together to emphasize his point. "You just hit 'em so hard they don't get back up! Like—POW!"

 

As Katsuki’s hands collided, a sharp, distinct CRACK echoed through the playroom.

 

A flash of bright orange light illuminated the space between his palms, accompanied by the distinct smell of burnt sugar and ozone. Katsuki froze, his crimson eyes going wide. He pulled his hands apart. A small plume of gray smoke curled from his right palm.

 

The daycare went dead silent. The teachers stopped in their tracks. Izuku dropped his action figure, his green eyes practically vibrating with awe.

 

Katsuki stared at his palms, a slow, feral grin stretching across his face. He focused, flexing his fingers, and—Pop! Pop! Crackle!—a series of miniature, firecracker explosions danced across his skin.

 

"Did you see that?!" Katsuki yelled, thrusting his sparking hands into the air. "I got it! I got my Quirk!"

 

The children swarmed him, erupting into cheers of amazement. Katsuki basked in the glory, already declaring himself the future Number One Hero. But through the crowd, his eyes found Izuku.

 

Izuku was smiling, bouncing on his heels with genuine excitement for his brother. "That’s amazing, Kacchan! It’s an emitter type! It smells like Mom’s lotion but it sparks like Dad’s sweat!"

 

"Obviously it's amazing, I'm amazing!" Katsuki boasted, crossing his arms, though he kept sparking his palms just to watch the flashes.

 

But when they returned home that evening, the celebrations were somewhat lopsided. Mitsuki baked a cake, and Masaru ruffled Katsuki’s hair with deep pride. Izuku clapped and cheered, completely supportive, but that night, as the twins lay in their adjacent beds, the silence felt heavy.

 

"Hey. Nerd," Katsuki whispered across the dark room.

 

Izuku shifted under his All Might blanket. "Yeah?"

 

"Don't go crying if yours is some boring Quirk like Dad's."

 

"Dad's Quirk isn't boring," Izuku replied defensively.

 

"It's not hero material," Katsuki stated with absolute four-year-old certainty. "But whatever. Even if you're a dud, I'll let you be my sidekick."

 

Izuku frowned in the dark. "I'm not going to be a sidekick. I'm going to be Number One, just like you."

 

"Can't both be Number One, Izuku."

 

"We'll see."

 

The next forty-eight hours were a crucible of anxiety for Izuku. He tried rubbing his hands together. He tried holding his breath. He tried jumping off the couch. Nothing happened. The fear that he might be part of the twenty percent—the Quirkless—began to gnaw at the edges of his mind.

 

Two days later, Izuku sat at the kitchen table, aggressively scribbling in a spiral-bound notebook. It was his first "Hero Analysis" journal, though at this age, it mostly consisted of crayon drawings of All Might and badly spelled notes about Katsuki's new explosions.

 

Izuku was frustrated. He couldn't get the drawing of Katsuki's sparks right. The crayon kept snapping under his grip. His palms were sweating profusely, his heart racing with a mix of concentration and underlying panic about his own quirkless status.

 

"Stupid crayon," Izuku muttered, pressing his sweaty fingertips hard against the paper to smudge the orange color.

 

He wanted it to look sharp. He wanted it to look powerful. He focused all his frustration, all his desire to stand on equal footing with his brother, into his fingertips.

 

FWOOSH—BANG!

 

The sound wasn't the sharp, concussive pop of Katsuki's explosions. It was a high-pitched, concentrated hiss followed by a cracking detonation.

 

A jet of searing white-hot flame shot from Izuku's index and middle fingers, punching a perfectly circular, charred hole straight through the notebook, through the kitchen table, and scorching the linoleum floor below.

 

Izuku fell backward out of his chair, yelping in surprise. The kitchen was instantly filled with a thick, white smoke and the sharp, chemical stench of ignited nitroglycerin.

 

Mitsuki came charging into the kitchen, a dish towel in hand, her red eyes wide with panic. "What happened?! Are you hurt?!"

 

Katsuki, who had been watching TV in the living room, bolted in right behind her.

 

Izuku sat on the floor, coughing, blinking through the smoke. He looked down at his right hand. His fingertips were smoking, glowing with a faint, residual heat. He looked up at the smoking, perfectly round hole in the thick oak table.

 

Katsuki stared at the hole, then back to Izuku's hands.

 

Izuku looked up, a massive, trembling smile breaking across his face. "Mom... Kacchan... I think I found it."

 

Katsuki marched over, peering through the hole in the table, noting the sheer penetration power. He looked at Izuku, his competitive grin returning, sharper than ever. "About time, Nerd."

 

 

 

From that day forward, the trajectory of their lives was irrevocably bound to the explosive power they wielded. But as they grew, it became abundantly clear that while they shared the same Quirk on paper—Explosion—the mechanics and applications of their powers were fundamentally different.

 

By the time they were eight years old, they had become the undisputed kings of their neighborhood. They were wild, loud, and entirely fearless.

 

Katsuki’s quirk was a blunt instrument of mass destruction. He secreted nitroglycerin-like sweat from the palms of his hands. The more he sweat, the bigger the blast. His explosions were concussive, expanding outward in massive shockwaves of fire and force. He fought with instinct, leaping into the fray with wide swings and roaring blasts that shattered obstacles and sent opponents flying.

 

Izuku’s quirk, however, was a surgeon’s scalpel. His sweat glands were hyper-concentrated in his fingertips and the center of his palms. The fluid he produced was highly volatile, igniting with far less friction than Katsuki’s. While he couldn't produce the massive, area-of-effect shockwaves his brother could without severe recoil, Izuku had control. He could manipulate the pressure of his ignition. He could fire off rapid, localized bursts resembling bullets of compressed air and fire. Furthermore, his sweat had a unique property: by burning it at a lower temperature, he could generate immense, blinding clouds of thick white smoke.

 

Where Katsuki was the bomb, Izuku was the detonator and the smokescreen.

 

They were an absolute terror to local bullies. The neighborhood kids called them the "Twin Dragons of Aldera."

 

One summer afternoon, when they were ten, Katsuki and Izuku were exploring the woods behind the local park. Izuku was muttering to himself, scribbling in Hero Analysis for the Future, Vol. 4, documenting the recoil limits of his own wrists, while Katsuki was busy blowing up an abandoned refrigerator they had found in a ditch.

 

"Hey! What do you think you're doing in our territory?!"

 

The twins turned. A group of five older boys, middle schoolers, had emerged from the tree line. The leader, a tall boy with rocks protruding from his knuckles, glared at them.

 

"Your territory?" Katsuki sneered, stepping away from the smoldering refrigerator, small pops echoing from his palms. "I don't see your name on it, Pebble-Hands."

 

"You cocky little brats," the older boy growled, stepping forward, his lackeys cracking their knuckles and activating minor manifestation quirks. "We're taking this spot. Scram before we make you."

 

Izuku calmly closed his notebook, tucking it into his yellow backpack. He didn't look afraid. If anything, he looked analytical, his green eyes scanning the five boys, calculating their weight, their stance, and their quirks.

 

"Kacchan," Izuku said, his voice calm, "the two on the left have mutation quirks. Increased muscle density, probably. The leader has stone skin. The other two are hanging back, likely emitter types or weak."

 

"I don't care what they are, Deku!" Katsuki roared, a feral grin splitting his face. He bent his knees, explosions sparking to life in his hands. "I'm gonna blast 'em all the same!"

 

"Deku?" the leader mocked. "What kind of stupid nickname is that? Means 'useless', doesn't it?"

 

Katsuki’s grin vanished. His eyes narrowed into crimson slits. "Shut up. I'm the only one who gets to call him that. And it doesn't mean useless. It means he's the one who's gonna kick your ass while you're busy looking at me."

 

Before the older boys could process the threat, the twins moved.

 

It was a terrifying display of synchronicity. Katsuki launched himself forward, using an explosion behind him to bridge the gap in a millisecond. He went straight for the leader, unleashing a massive right hook fueled by a concussive blast. The leader raised his stone arms to block, but the sheer kinetic force sent him skidding backward into the dirt.

 

Simultaneously, Izuku dashed to the right. The two muscle-bound lackeys lunged for him. Izuku didn't brace for a physical hit. Instead, he raised his left hand, thumb and middle finger pressed together. Snap.

 

A piercing flashbang explosion detonated right in the faces of the two boys, blinding them. As they stumbled out, clutching their eyes, Izuku dropped low, spinning on his heel. He fired a rapid succession of pinpoint explosions from his fingertips against the ground, propelling himself upward into a somersault. Mid-air, he spun, firing a concentrated blast at the back of the first boy's knees, buckling his legs, before landing gracefully and sweeping the legs of the second.

 

The remaining two boys in the back turned to run.

 

"Where do you think you're going?!" Katsuki roared. He raised his hand to blast them, but Izuku was already there.

 

"Smokescreen!" Izuku shouted. He clapped his hands together, regulating the heat of his ignition. Instead of fire, a massive, billowing cloud of thick, choking white smoke erupted from his palms, instantly blanketing the area and swallowing the fleeing boys.

 

Coughing and disoriented, the boys stumbled blindly through the fog, only to meet the explosive palms of Katsuki Bakugo waiting on the other side.

 

Within two minutes, the fight was over. The five older boys were groaning on the ground, nursing singed clothes and bruised egos.

 

Katsuki stood over the leader, smoke rising from his shoulders. "Next time you see us," Katsuki sneered, "you walk the other way."

 

Izuku walked out of the dissipating smoke, dusting off his shorts. He pulled out his notebook and jotted something down. "Your stone armor was brittle," Izuku told the groaning leader in a completely conversational tone. "Against concussive heat, it fractures easily. You should work on layering your minerals."

 

The older boys scrambled away in sheer terror.

 

Katsuki scoffed, wiping a smudge of dirt off his cheek. "You give out too much free advice, Nerd."

 

Izuku smiled, a bright, disarming expression that sharply contrasted his lethal quirk. "Just trying to help, Kacchan. Besides, your right hook is getting predictable. You're over-relying on your right palm for propulsion."

 

"I'll show you predictable!" Katsuki yelled, lunging at his brother.

 

Izuku laughed, firing a blast at the ground to dodge, and the two brothers chased each other through the woods, the sound of their explosive bickering echoing through the trees.

 

This was their dynamic. A perpetual, high-octane rivalry. Katsuki was the undisputed alpha of their peer group, abrasive and arrogant, but he never crossed the line into true villainous bullying, entirely because Izuku was always there to check him. Izuku was the only person in the world Katsuki considered an equal. If Katsuki got too rough with a classmate, Izuku would step in. A sparring match would ensue, destroying half the playground, ending in a draw that effectively distracted Katsuki from whatever had angered him in the first place.

 

Izuku, conversely, used Katsuki as his benchmark. Izuku was naturally kinder, deeply empathetic, and obsessed with the theory of heroism. But underneath his polite smiles and frantic note-taking was a competitive fire just as hot as Katsuki’s. Izuku didn't just want to be a hero; he wanted to be the absolute best. And to be the best, he had to be able to beat Katsuki.

 

 

 

By the time they reached fourteen, their final year at Aldera Junior High, their reputations preceded them.

 

The classroom buzzed with mundane chatter as the homeroom teacher walked in, holding a stack of papers.

 

"Since you're all third years, it's time for you to think seriously about your future," the teacher announced. "I'll pass out these career aptitude handouts, but..." He paused, a smirk crossing his face as he tossed the papers into the air. "I know you all want to go into the hero track!"

 

The classroom erupted. Quirks flashed, stretched, and manifested across the room as the students cheered.

 

"Yes, yes, you all have wonderful quirks," the teacher said, trying to regain order. "But remember, using your quirks in school is against the rules."

 

"Sensei! Don't lump us in with these total losers!"

 

The loud, arrogant voice cut through the noise. Katsuki was leaning back in his chair, his feet resting casually on his desk. He wore his uniform with the collar open, a permanent scowl of superiority etched onto his features.

 

"Me and my brother are in a completely different league than these extras," Katsuki proclaimed, crossing his arms.

 

The class bristled. "Hey, uncalled for, Bakugo!" a student with elongated fingers yelled.

 

"Shut up, you minor-league NPCs!" Katsuki barked back, small explosions popping from his palms. "You'll be lucky to end up as sidekicks to some D-lister!"

 

Sitting at the desk immediately to Katsuki’s right, Izuku let out a long, long sigh. He was dressed far more neatly, his uniform buttoned, his notebook open on his desk. But he didn't apologize for his brother.

 

"Kacchan, statistically speaking, only about two percent of applicants make it into the top-tier hero agencies, so you're not wrong," Izuku said calmly, tapping his pencil against his notebook. "But calling them NPCs is tactically unsound. You never know when one of their quirks might prove useful in a support role."

 

"I don't need support!" Katsuki snapped.

 

The teacher adjusted his glasses, looking at the papers on his clipboard. "Ah, yes. You two applied for U.A. High School, didn't you?"

 

A hushed silence fell over the classroom. U.A. was the pinnacle of hero academies. The acceptance rate was abysmally low.

 

"U.A.? The national school?!"

"I heard they have a 0.2% acceptance rate!"

 

Katsuki jumped onto his desk, a manic grin on his face. "That's exactly why it's the only place for us! We aced the mock tests. We've got the quirks, we've got the brains, and we're going to surpass All Might himself!"

 

Izuku remained seated, but he looked up, his green eyes burning with an intense, quiet confidence. "We're going to take the top two spots," Izuku said, his voice carrying clearly through the room. "The Number One and Number Two heroes of the next generation. That's the plan."

 

"Yeah, and I'll be Number One!" Katsuki yelled, pointing a thumb at his chest.

 

"Only if you fix your sloppy footwork, Kacchan," Izuku countered without missing a beat.

 

Katsuki’s eye twitched. "My footwork is flawless, you damn nerd! You wanna take this outside?!"

 

"We have a sparring session scheduled at 1700 hours anyway," Izuku replied, checking his watch. "I'll prove it to you then."

 

The rest of the class watched the exchange with a mixture of awe and absolute dread. The Bakugo twins were a force of nature. No one dared cross them, and no one doubted for a second that they would make it into U.A.

 

 

 

Later that afternoon, the sun began to dip below the horizon, casting long, dramatic shadows across Ground Zero—the name they had given to a secluded, abandoned rock quarry on the outskirts of the city. The area was surrounded by high concrete walls and filled with jagged boulders, providing the perfect playground for two boys who needed to blow things up without getting arrested.

 

The air in the quarry was already thick with the smell of ozone and burnt rock.

 

Katsuki stood fifty yards away, stretching his shoulders, a savage grin on his face. He was in a black tank top, sweat already glistening on his skin.

 

Izuku stood opposite him, wearing a dark green athletic shirt, wrapping his wrists with thick, white athletic tape. He needed the tape. The recoil of his focused explosions took a heavy toll on his joints if he wasn't careful. He finished the wrap, tightening the fabric, and locked eyes with his brother.

 

"No flashbangs to the eyes today, Nerd," Katsuki called out, crouching low into his starting stance, his hands poised behind him. "It pisses me off."

 

"Then don't look directly at my hands, Kacchan," Izuku replied, dropping into a light, bouncy fighting stance. His analytical mind was already running through a thousand scenarios, calculating the wind speed, the uneven terrain, and Katsuki’s current mood. "Ready?"

 

"DIE!"

 

That was Katsuki’s version of 'yes.'

 

Katsuki initiated the combat. He blasted his hands behind him, launching himself through the air like a human missile. He cleared the fifty-yard gap in two seconds, rearing his right arm back for a devastating mid-air strike.

 

Izuku didn't flinch. As Katsuki brought his explosive palm down, Izuku sidestepped, firing a short, sharp blast from his fingertips against the ground. The propulsion snapped his body to the left with whip-like speed.

 

Katsuki’s hand hit the dirt where Izuku had just stood. BOOM. The ground cratered, sending dirt and rocks flying like shrapnel.

 

Before Katsuki could recover his stance, Izuku was already moving. Using the momentum from his dodge, Izuku pivoted, raising his right hand. Instead of aiming for Katsuki, he aimed at the loose rocks around Katsuki's feet.

 

Hiss-BANG!

 

Izuku’s concentrated blast shattered the rock, turning it into a spray of debris that pelted Katsuki’s legs.

 

Katsuki grunted, leaping back. "Cheap tricks!" he yelled. He threw both hands forward. Stun Grenade! A massive flash of light and heat erupted from his palms, aimed dead at Izuku.

 

Izuku reacted on pure instinct. He threw up a localized smokescreen, clapping his hands and releasing a thick cloud of white smoke to absorb the blinding light and heat.

 

The shockwave hit the smoke, dispersing it instantly, but Izuku was no longer there.

 

Where? Katsuki thought, his eyes darting.

 

Above.

 

Izuku had used the cover of the smoke to propel himself ten feet into the air. He was coming down fast, his body spinning, aiming a fierce, explosive-powered heel drop right at Katsuki’s head.

 

Katsuki looked up, grinning fiercely. He raised both arms, crossing them over his head, and detonated a massive explosion upward to meet Izuku’s strike.

 

The two blasts collided in mid-air. KRA-KOOM.

 

The shockwave rattled the entire quarry. The sheer force of Katsuki’s blast overpowered Izuku’s downward momentum, sending Izuku flying backward through the air.

 

Izuku gritted his teeth, righting himself mid-flight. He's stronger today, Izuku thought rapidly. He's been working on his grip strength to handle larger outputs.

 

As Izuku hurtled toward a massive boulder, he snapped his fingers, firing a sequence of rapid micro-explosions that acted like retro-rockets, slowing his momentum. He hit the boulder feet-first, his knees bending to absorb the shock, and instantly used the rock as a springboard.

 

Blast!

 

Izuku rocketed back toward Katsuki, zig-zagging wildly. He fired blasts from alternating hands, changing his trajectory in mid-air in erratic, unpredictable angles.

 

Katsuki tracked him, roaring in frustration. "Stop bouncing around like a damn rabbit!" Katsuki unleashed a barrage of explosions, trying to clip Izuku, but Izuku’s aerial mobility was too precise.

 

Izuku closed the distance. He feinted a blast with his right hand. Katsuki moved to counter, but Izuku instantly killed the ignition in his right and fired with his left, spinning his body like a top. He slipped past Katsuki's guard and drove an explosive-powered palm strike directly into Katsuki’s solar plexus.

 

The blast was highly concentrated, meant to knock the wind out of him without causing permanent damage.

 

Katsuki coughed, spit flying from his mouth, but his eyes burned with sheer, stubborn rage. Instead of falling back, Katsuki grabbed Izuku’s wrist with his left hand.

 

Izuku's eyes widened. A trap.

 

Katsuki grinned, blood on his teeth. "Gotcha."

 

Katsuki pulled Izuku in close and raised his right palm, glowing bright orange with maximum heat, aiming point-blank at Izuku's chest.

 

Izuku had a fraction of a second. He couldn't dodge. So, he fought fire with fire. He raised his free hand, pressing it flat against Katsuki's incoming palm.

 

"Don't do it, Izuku! It'll break your fingers!" Katsuki roared, a warning disguised as a threat.

 

"I'm not losing, Kacchan!" Izuku yelled back.

 

Both brothers ignited their quirks at maximum output simultaneously.

 

The resulting explosion was deafening. A sphere of pure, blinding concussive energy erupted between them. The force was so immense that it shattered the ground beneath their feet and sent both brothers flying violently in opposite directions.

 

Katsuki crashed into a pile of gravel, tumbling several times before skidding to a halt.

 

Izuku slammed into the dirt, rolling roughly, his tape-wrapped wrists smoking and his ears ringing furiously.

 

Silence descended on the quarry, save for the patter of falling rocks and the crackle of localized brush fires.

 

A minute passed.

 

Slowly, Katsuki sat up, groaning, rubbing his bruised chest. His tank top was scorched, his face covered in soot.

 

Across the crater, Izuku pushed himself onto his knees. He was panting heavily, looking at his right hand. The athletic tape was completely charred, and his fingers were trembling from the recoil, but they weren't broken. He managed a shaky, exhausted smile.

 

Katsuki glared at him, then let out a sharp, barking laugh. "You held back on the ignition, you idiot. You let my blast push you instead of fighting the full force."

 

"If I hadn't, we both would have shattered our hands," Izuku pointed out, wincing as he stood up, his legs shaking. "We have the U.A. entrance exam in ten months. I'm not breaking my arms before then."

 

"Tch. Coward," Katsuki spat, though there was no real malice in it. He stood up, cracking his neck. "Draw. Again."

 

"I... I think I'm out of sweat, Kacchan," Izuku admitted, wiping his soot-stained brow.

 

Katsuki scoffed, walking over to his discarded gym bag. He pulled out two water bottles and tossed one at Izuku. Izuku caught it with his left hand, his right still trembling slightly.

 

They sat on the edge of the blast crater, side by side, watching the sun finally dip below the horizon, painting the sky in vibrant shades of bruised purple and fiery orange. The adrenaline faded, leaving the comfortable, familiar exhaustion of a good fight.

 

"Ten months," Katsuki muttered, staring at the sky. He popped the cap off his water bottle and took a long swig. "Ten months until we show those U.A. elites what real power looks like."

 

Izuku took a sip of water, cooling his parched throat. He looked down at his smoking hands. They possessed a powerful quirk. A quirk suited for heroism. Yet, despite his strength, Izuku always felt a nagging sense of inadequacy when he watched the old video clips of All Might. All Might didn't just have power; he had an overwhelming presence. He saved people with a smile that banished fear.

 

Explosions caused fear. Izuku knew that. He and Katsuki possessed villainous-looking powers. Destructive. Violent. It was up to them to prove that they could use that destruction to protect.

 

"Kacchan," Izuku said quietly.

 

"What?"

 

"Do you really think we can surpass him? All Might?"

 

Katsuki turned his head, his crimson eyes locking onto Izuku’s green ones. The arrogance in Katsuki’s face melted away, replaced by an intense, burning sincerity.

 

"We made a vow, didn't we?" Katsuki said, his voice uncharacteristically quiet, yet carrying the weight of absolute conviction. "When we were four. We promised."

 

Izuku remembered. They had watched All Might’s debut video a thousand times. The disaster. The fire. The man who walked out of the flames carrying a hundred people on his back, laughing.

 

“I’m going to be just like him!” Katsuki had yelled, sparking his tiny palms.

“Me too! We’ll both be the best!” Izuku had chimed in.

“Then it’s a race, Deku. First one to surpass All Might wins.”

 

Izuku looked at his brother, feeling the fire reignite in his chest. He tightened his trembling right hand into a fist, ignoring the ache in his joints.

 

"Yeah," Izuku said, a determined smile spreading across his face. "We did."

 

Izuku held out his fist.

 

Katsuki looked at it, smirked, and bumped his knuckles against Izuku’s. The contact produced a tiny, shared spark of ignition—a miniature explosion that flared between their hands for a brief second before fading into the twilight.

 

"I'm not losing to you, Nerd," Katsuki promised.

 

"I'd like to see you try, Kacchan," Izuku replied.

 

They were the Twin Dragons of Aldera. They were explosive, they were unstoppable, and they were on a collision course with destiny. But neither of them knew that the path to Number One would soon diverge in a way they could never have imagined, all because of a chance encounter with a Sludge Villain, a dying Symbol of Peace, and a secret power passed down through generations.

 

For now, they were just two brothers, sitting in a crater of their own making, staring up at the stars, waiting for their real journey to begin.

 

The afternoon sun hung low over Musutafu, casting long, golden shadows across the bustling streets. The day had been utterly ordinary, a mundane stretch of mathematics, modern literature, and homeroom announcements that felt like a holding pattern for the rest of their lives.

 

For the Bakugo twins, ordinary was a concept they tolerated, not one they enjoyed.

 

Inside the classroom of Aldera Junior High, the final bell of the day rang, its shrill electronic trill cutting through the stifling afternoon heat. Chairs scraped against the linoleum floor as students eagerly packed their bags.

 

Izuku Bakugo remained seated for a moment, his pencil flying across the page of Hero Analysis for the Future, Vol. 13. His eyes were glued to a video playing on his cracked smartphone, tucked discreetly behind his textbook. It was footage from earlier that morning—a colossal villain with a shark-like mutation had caused a rampage at Tatooin Station, only to be stopped by the newly debuted pro-hero, Mt. Lady.

 

"Her gigantification quirk is highly effective for crowd control and heavy physical damage," Izuku muttered under his breath, his hand moving in a blur. "But the collateral damage to the surrounding infrastructure is a massive liability. Her mobility in narrow city streets is severely restricted, meaning she's best suited for wide-open commercial districts or coastal defense. Plus, if she miscalculates her landing by even a few feet, she risks civilian casualties."

 

"Are you still mumbling about that giant bimbo, Nerd?"

 

A shadow fell over Izuku’s desk. He looked up, blinking the intense focus from his green eyes, to see his brother standing over him. Katsuki had his backpack slung carelessly over one shoulder, his uniform collar unbuttoned, and a look of profound boredom etched onto his face.

 

"I'm not mumbling," Izuku defended mildly, capping his pencil. "I'm analyzing. Mt. Lady has a lot of raw power, but her tactical application is sloppy. If a villain has underground mobility or aerial superiority, she's a sitting duck."

 

Katsuki scoffed, a tiny spark of orange ignition popping from his thumb and index finger. "Who cares about aerial superiority? If you punch something hard enough, it goes down. That's all there is to it. If she wasn't so busy posing for the cameras, she could have finished that shark guy in three seconds flat."

 

"Not every fight is about hitting the hardest, Kacchan," Izuku sighed, finally sliding the notebook into his yellow backpack and standing up. "Sometimes it's about hitting the smartest."

 

"Yeah, yeah. Keep telling yourself that while I'm taking all the glory," Katsuki smirked, turning on his heel. "Come on. The hag is making spicy curry tonight and if we're late, she's gonna start screeching."

 

Izuku smiled, shaking his head as he followed his brother out of the classroom.

 

Their walk home was a familiar routine. They rarely walked shoulder-to-shoulder; Katsuki always strode a half-pace ahead, leading the way with a purposeful, aggressive stride, while Izuku walked slightly behind, his eyes constantly scanning their surroundings. It wasn't submissiveness on Izuku's part—it was a tactical habit. Izuku liked having a clear field of vision, observing the flow of foot traffic, the architecture of the buildings, and the quickest escape routes. Katsuki, on the other hand, just wanted to get from Point A to Point B as quickly as possible.

 

"Ten months," Katsuki said suddenly, breaking the comfortable silence as they veered away from the main thoroughfare and onto a quieter side street. "We need to ramp up our training schedule. Ground Zero every day after school, no excuses. I'm going to need to increase my sweat reservoir if I want to sustain maximum output for the U.A. physical exams."

 

"Agreed," Izuku nodded, his mind already formulating a training regimen. "I need to work on my heat regulation. If I can lower the combustion temperature of my smokescreens by ten degrees, I can increase the density of the smoke by twenty percent without burning off the excess oxygen in the area."

 

Katsuki glanced back over his shoulder, a competitive gleam in his crimson eyes. "Just make sure you don't choke yourself out, Deku. I don't want an easy win."

 

"You couldn't get an easy win against me if you tried, Kacchan."

 

They turned a corner, approaching a pedestrian underpass that cut beneath a large, elevated train track. The tunnel was cool, damp, and cast in deep shadows, a stark contrast to the bright afternoon sun they had just left behind. Condensation dripped from the concrete ceiling, pooling in shallow, murky puddles on the cracked asphalt.

 

"Stinks like a sewer in here," Katsuki grumbled, kicking a discarded soda can. It clattered against the wall, the sound echoing hollowly down the tunnel.

 

"City maintenance has been slacking in this sector," Izuku noted, looking up at the flickering fluorescent light overhead. "It's a textbook ambush point for muggers. Poor lighting, limited exits, acoustic dampening..."

 

Izuku stopped walking.

 

The hair on the back of his neck stood up. His green eyes narrowed, his acute senses picking up on something wrong. It wasn't a sound, exactly. It was a shifting of the air pressure behind them, accompanied by a wet, heavy, gurgling noise, like thick mud boiling over a stove.

 

"Kacchan. Stop." Izuku's voice was low, instantly stripped of its previous warmth.

 

Katsuki halted, picking up on his brother’s tonal shift immediately. He didn't turn around right away. Instead, his hands dropped to his sides, his fingers curling inward as he primed his sweat glands. "What is it?"

 

"Behind us," Izuku whispered.

 

From the grate of the sewer drain near the entrance of the tunnel, a dark, viscous liquid was pouring upward, defying gravity. It didn't flow; it heaved, expanding and solidifying into a massive, towering wave of foul-smelling, dark green sludge.

 

Two massive, bulbous eyes materialized within the fluid mass, followed by a wide, jagged maw filled with crooked, uneven teeth.

 

"An invisible cloak..." a deep, wet voice echoed from the sludge, a sound that made Izuku's stomach turn. "A medium-sized body... and a powerful Quirk hiding inside... Oh, this is perfect. Absolutely perfect."

 

Before Izuku could shout a warning, the sludge surged forward with terrifying, explosive speed.

 

It didn't target Izuku. It sensed the raw, aggressive energy radiating from Katsuki and went straight for him.

 

"Kacchan, move!" Izuku yelled, his hands igniting instinctively.

 

Katsuki spun around, his eyes widening at the monstrous wave of fluid bearing down on him. "What the hell—!"

 

He threw his right hand forward, detonating a massive, concussive blast. BOOM! The explosion lit up the dark tunnel, sending a shockwave that rattled Izuku's teeth.

 

But the explosion didn't stop the creature. The sludge simply parted around the blast, absorbing the kinetic force and heat like a sponge, before crashing down over Katsuki like a tidal wave.

 

"GACK—!"

 

Katsuki's scream was instantly muffled as the thick, foul liquid forced its way into his mouth and up his nose. The sludge wrapped around his arms and legs, hoisting him into the air.

 

"Don't struggle, kid!" the Sludge Villain laughed, his voice bubbling violently. "It'll only hurt for about forty-five seconds! You're my hero! With a body and a Quirk like yours, I can finally escape him!"

 

Izuku froze for exactly one millisecond.

 

The terror of seeing his brother swallowed alive threatened to paralyze him, but years of combat training, years of analyzing crisis scenarios, overrode his panic. The analytical machine in his brain roared to life, dissecting the situation in a fraction of a second.

 

Fluid body. Highly viscous. Highly resistant to concussive force and blunt trauma. Weaknesses: Extreme temperatures, cellular disruption, and vital points.

 

Izuku’s eyes locked onto the two bulbous, floating eyeballs within the sludge. Target acquired.

 

"Let him go!" Izuku roared.

 

He didn't throw his backpack. He didn't hesitate. Izuku dropped his center of gravity, raised both hands behind him, and fired a continuous, high-pressure thrust from his palms.

 

FWOOSH!

 

The propulsion launched Izuku forward like a fired bullet. He closed the twenty-foot gap in an instant. The Sludge Villain barely had time to shift its gaze before Izuku was upon him.

 

"A second brat?!" the villain sneered. A tendril of solidifying sludge whipped out like a bat, aiming to swat Izuku out of the air.

 

Trajectory shift.

 

Mid-air, Izuku killed the thrust in his left hand and fired a micro-burst from his right, spinning his body out of the path of the tendril. As he spun, he extended his left arm, focusing every ounce of his nitroglycerin sweat into his index and middle fingers.

 

He didn't want a concussive blast. A concussive blast would just hit the fluid and disburse. He needed a piercing weapon.

 

"Armor Piercing: Needle Blast!"

 

CRACK!

 

A thin, searing line of concentrated, white-hot fire erupted from Izuku's fingertips. It didn't push; it punctured. The blast lanced directly into the villain’s right eye.

 

The Sludge Villain shrieked in agony, an unearthly, bubbling howl. The pain caused the creature to flinch, its grip on Katsuki loosening just a fraction.

 

It was all the opening Katsuki needed.

 

Gasping for air, Katsuki ripped his right arm free from the sludge. His eyes were bloodshot, his face pale, but his fury was absolute. He pressed his palm directly against the inside of the sludge mass encapsulating his chest.

 

"DIE, YOU BASTARD!" Katsuki roared, detonating an explosion at point-blank range, entirely within the fluid.

 

The muffled THUMP vibrated through the air. The sludge bulged outward uncontrollably, boiling from the inside out, forcing the villain to violently regurgitate Katsuki’s upper half to relieve the internal pressure.

 

Katsuki hung from the creature's lower mass, coughing violently, violently inhaling the damp, foul air of the tunnel.

 

"You little shits!" the villain roared, its singular remaining eye wide with fury. "I'll crush you both!"

 

The sludge erupted into a dozen spiked tendrils, thrashing wildly.

 

Izuku landed gracefully on his feet, immediately sliding backward on the damp asphalt. He raised his hands. He's panicked. His attacks are erratic. We need to break his structural integrity at the same time.

 

"Kacchan!" Izuku shouted over the gurgling chaos. "Synchronize!"

 

Katsuki, still half-embedded in the slime, wiped a trail of foul liquid from his mouth. He looked at Izuku, his crimson eyes locking onto the calm, burning green of his brother's. They didn't need words. They had practiced this maneuver a hundred times at Ground Zero.

 

Izuku sprinted forward, dodging two sweeping tendrils. He dropped to his knees, sliding under a third, and threw his hands out toward the massive base of the sludge pile. He regulated his sweat, lowering the combustion temperature, and clapped his hands together.

 

"Smokescreen: Heavy Blanket!"

 

A massive, incredibly dense cloud of thick white smoke exploded from Izuku’s palms, completely engulfing the lower half of the tunnel. It blinded the villain, completely obscuring Katsuki from view, but more importantly, it displaced the oxygen and filled the air with volatile, unignited nitroglycerin fumes.

 

"Where are you?! I can't see!" the villain panicked, thrashing blindly in the thick white fog.

 

From the center of the smoke, Katsuki’s voice rang out, laced with pure, unadulterated venom.

 

"Right here, you piece of shit."

 

Katsuki had used the distraction to fully extract his legs. He crouched within the smoke, his hands pressed together, generating as much heat as his body could handle.

 

Simultaneously, from the perimeter of the smoke, Izuku aimed both of his hands directly at the center of the mass.

 

"Now!" Izuku yelled.

 

"DOUBLE DETONATION!"

 

Katsuki unleashed a massive, concussive shockwave from the inside, while Izuku fired a twin-barrel, high-pressure thermal lance from the outside.

 

The two different types of explosions met in the middle. The sheer kinetic force of Katsuki's blast ripped the fluid apart, while the intense, concentrated heat of Izuku's blast superheated the liquid, instantly vaporizing a massive chunk of the villain's body.

 

The combined explosion blew the roof of the underpass upward. Concrete cracked and groaned, dust raining down as the shockwave blasted out of both ends of the tunnel, shattering the glass of a nearby streetlamp.

 

The Sludge Villain was blown to pieces, its form splattering violently against the walls, ceiling, and floor in a million harmless, sizzling droplets.

 

Katsuki dropped to his hands and knees on the asphalt, coughing and hacking, his lungs burning. Izuku stumbled backward, his legs giving out as he fell onto his rear, his hands smoking heavily, chest heaving.

 

The tunnel fell dead silent, save for the dripping of evaporated sludge and the ragged breathing of the two boys.

 

"Did... did we get him?" Izuku panted, his vision swimming slightly from the adrenaline crash.

 

Katsuki spit a wad of green slime onto the ground, looking utterly murderous. "Damn right we did. Disgusting piece of garbage..."

 

But their relief was terribly premature.

 

From the puddles on the ground, the sludge began to twitch. The liquid drops began pulling themselves together, drawn by some magnetic force, coalescing back into a singular mass.

 

Izuku watched in horror. Cellular regeneration? No, he's a liquid. Unless we completely vaporize him or contain him in a sealed vessel, physical attacks are utterly useless. He just reforms.

 

"Kacchan..." Izuku whispered, his voice trembling as he tried to raise his smoking hands. His joints ached furiously. "He's... he's coming back."

 

Katsuki forced himself to his feet, his hands sparking, but the sparks were weak. The sludge had suffocated him, draining his stamina and lowering his core body temperature. "I'll just blast him again," Katsuki growled, though his voice lacked its usual booming confidence.

 

The Sludge Villain reformed, towering over them, larger and angrier than before. "You ruined my camouflage! You burnt my eye! I'm going to tear you both limb from limb and wear your skins!"

 

The villain lunged.

 

The boys braced themselves, too exhausted to dodge, too stubborn to run.

 

But the blow never landed.

 

Suddenly, a massive figure dropped from the sky, landing right at the entrance of the tunnel. The impact shattered the pavement, sending a shockwave that made the ground tremble.

 

The air pressure in the tunnel changed instantly. It was as if all the oxygen had been sucked out of the room, replaced by an overwhelming, suffocating aura of pure, unadulterated power.

 

Izuku’s eyes widened. He knew that silhouette. He knew the massive, V-shaped torso, the twin tufts of blonde hair standing tall, and the brilliant, fearless smile that seemed to radiate light in the dark tunnel.

 

"It is fine now, young men!" a booming voice echoed, vibrating in Izuku's chest.

 

The Sludge Villain froze, sheer terror rippling through his fluid form. "Y-You...!"

 

The man stepped forward, drawing his massive right arm back. The muscles in his arm bulged, tearing the fabric of his white t-shirt.

 

"For I AM HERE!"

 

"TEXAS..."

 

All Might threw the punch. He didn't even make contact with the villain. He punched the air itself.

 

"...SMASH!"

 

The resulting wind pressure was apocalyptic. A localized hurricane erupted within the confines of the tunnel. The sheer force of the air pressure hit the Sludge Villain like a freight train, tearing his liquid form into atomic, scattered droplets instantly.

 

Izuku and Katsuki were thrown backward, screaming as the wind sent them tumbling end over end. They crashed into a pile of trash bags at the far end of the tunnel, groaning in pain.

 

As the wind died down, Izuku opened his eyes. He looked up at the ceiling of the tunnel. The sheer air pressure of All Might's punch had created an updraft so powerful that it had summoned clouds outside. A light rain began to fall through the cracked concrete above.

 

He changed the weather, Izuku thought, his mind struggling to comprehend the sheer magnitude of what he had just witnessed. With a single punch... he changed the weather.

 

All Might stood amidst the scattered droplets, holding two large plastic soda bottles. He moved with blinding speed, scooping up the remains of the villain and sealing them tightly within the bottles.

 

Within seconds, the Number One Hero was standing over the two boys, his hands on his hips, his signature smile shining down at them.

 

"Excellent work holding him off, you two! But I apologize for getting you caught up in my villain hunt! Mistakes were made, but all is well!"

 

Katsuki stared, utterly speechless, his mouth hanging open. The boy who was never short on words, who always had a boast or a threat ready, was completely paralyzed by awe.

 

Izuku was equally starstruck. This was his idol. The man he had studied, worshipped, and dreamed of surpassing since he was four years old.

 

"A-All Might..." Izuku stammered, scrambling to his knees. He looked around frantically. "M-My notebook! Kacchan, where's my notebook? I need an autograph!"

 

Izuku found his yellow backpack, ripping out Hero Analysis for the Future, Vol. 13, and practically shoving it toward the colossal hero.

 

All Might laughed—a booming, hearty sound. "Already signed, young man!"

 

Izuku flipped it open. A massive, sprawling signature took up two entire pages. Izuku looked like he was going to pass out from pure joy. "Thank you! I'll treasure it forever! It's a family heirloom!"

 

Katsuki finally snapped out of his daze, scrambling to his feet, scowling to hide his embarrassment. "Tch. I didn't need your help," he muttered to All Might, brushing dirt off his uniform. "We had him on the ropes. The Double Detonation weakened his molecular structure."

 

All Might looked at Katsuki, his smile faltering just a fraction, though his eyes gleamed with interest. "Is that so? You possess a remarkably powerful Quirk, young man! The concussive force you generated was impressive! However, had I not intervened, the villain would have reformed. But you showed great resilience!"

 

Katsuki crossed his arms, looking away, his pride bruised. He had been captured. He had been suffocating. Izuku had to buy him an opening. It was a humiliating reality check.

 

"Well, I must be off!" All Might declared, patting his pockets to ensure the bottles were secure. "I must deliver this miscreant to the police! Stay out of trouble, you two!"

 

All Might bent his knees, preparing to leap.

 

"Wait!" Izuku yelled, taking a step forward.

 

"No time to wait! A hero is always fighting against time!" All Might boomed, and with a thunderous crack, he launched himself into the sky, disappearing over the city skyline in a matter of seconds.

 

The two brothers stood alone in the wrecked underpass, the adrenaline rapidly leaving their systems, replaced by the deep, aching exhaustion of battle.

 

Sirens wailed in the distance. The explosion had definitely attracted attention.

 

"Come on," Katsuki grunted, turning and walking away. "Let's get out of here before the cops show up and start asking stupid questions."

 

Izuku watched him go. "Kacchan, you're limping. We should get you checked out by a paramedic."

 

"Shut up, Nerd. I'm fine." Katsuki didn't look back. His fists were clenched so tightly his knuckles were white. "I was careless. I let him sneak up on me. That's never happening again."

 

Izuku knew that tone. It was the tone Katsuki used when he was furiously angry at himself. Izuku knew better than to push it. "Alright. I'll take the long way around. I want to check out the blast radius."

 

"Whatever. Just don't be late for dinner," Katsuki muttered, turning the corner and disappearing from sight.

 

Izuku sighed, picking up his backpack. He slung it over one shoulder, wincing at the flare of pain in his wrist. He began walking in the opposite direction, toward the local park, needing a moment of quiet to process everything that had just happened.

 

He had fought a real villain. He had saved Kacchan. He had met All Might.

 

As Izuku walked through the deserted, tree-lined paths of the park, the evening air cooling his sweat-dampened skin, he replayed the fight in his head. My thermal lance was effective, but it takes too long to charge the necessary heat. If I can figure out a way to spark the ignition closer to the base of my fingers without burning my knuckles...

 

"A very analytical mind."

 

Izuku stopped dead in his tracks.

 

The voice was hollow, raspy, and completely unfamiliar.

 

Izuku spun around, his hands instinctively coming up, ready to ignite his sweat.

 

Standing beneath the shade of a large oak tree was a man. He was shockingly emaciated, his cheekbones sharp enough to cut glass, his eyes sunken deep into their sockets. He wore baggy clothes that looked three sizes too big, and he was hacking into a blood-stained handkerchief. His blonde hair hung limply in his face.

 

"Who are you?" Izuku demanded, keeping his distance. "If you're a villain, I'm warning you, I have a powerful combat Quirk."

 

The skeletal man wiped his mouth, offering a weak, self-deprecating smile. "I know you do, young Bakugo. I just watched you use it."

 

Izuku's eyes widened. Bakugo? How does he know my name?

 

Suddenly, the man stood up straight. A strange, smoking aura surrounded him. His muscles expanded violently, his spine straightening, his entire physical form inflating like a balloon until the emaciated man was replaced by the towering, muscular physique of the Symbol of Peace.

 

"I AM HERE!" All Might announced, striking a pose, though a trail of blood leaked from the corner of his brilliant smile.

 

Izuku dropped his backpack, his jaw hitting the floor. "A-A-A-ALL MIGHT?!"

 

Before Izuku could process this impossibility, All Might deflated in a massive cloud of steam, reverting back to the skeletal, coughing figure.

 

"Wh-What?! How?! You're deflating! Are you an imposter?! A fake?! A shapeshifter?!" Izuku panicked, taking a step back.

 

"Calm down, young man," All Might sighed, sitting down heavily on a park bench. "I assure you, I am the real deal. What you see before you is the truth behind the Symbol of Peace."

 

All Might lifted his baggy shirt, revealing a massive, horrifying scar that spider-webbed across his left side. The tissue was twisted and sunken, a devastating wound that made Izuku physically nauseous just looking at it.

 

"Five years ago," All Might explained, his voice losing its booming theatricality, settling into a grave, quiet timbre. "My respiratory system was nearly destroyed. I lost my whole stomach. Through repeated surgeries, I've managed to survive, but my time as a hero... my limit... is down to about three hours a day."

 

Izuku stared at the scar, his encyclopedic knowledge of hero trivia racing through his brain. "Five years ago... Toxic Chainsaw? No, he couldn't have caused that kind of damage."

 

All Might chuckled weakly. "You know your stuff. No, this fight was kept under wraps to the public. The Symbol of Peace cannot be seen as vulnerable. If the world knew I was this weak, society would collapse."

 

Izuku felt the weight of the revelation pressing down on him. The Number One Hero, the invincible god of their world, was a mortal man slowly dying from a grievous injury. "Why... why are you showing me this? Showing me your weakness?"

 

All Might fixed his sunken, piercing blue eyes on Izuku. "Because, young man, I have been searching for a successor. And I believe I have found him."

 

Izuku blinked. "A successor? But... my Quirk. I have Explosion. It's powerful, yes, but Kacchan's is stronger. His output is—"

 

"I am not interested in your brother's Quirk," All Might interrupted gently. "Yes, your brother has a magnificent power. He is strong, proud, and undoubtedly possesses the drive to be a great hero. But power alone does not make a Symbol."

 

All Might stood up, walking slowly toward Izuku.

 

"When that villain attacked... I was watching. I had dropped the bottles when I landed earlier, and the villain escaped. I was out of time. I couldn't transform. I stood in that crowd, a useless bystander, watching your brother suffocate."

 

All Might's fists clenched tightly at his sides. "The other pro heroes were waiting for a hero with a more suitable Quirk. They were calculating the odds. They were hesitating."

 

All Might pointed a long, bony finger directly at Izuku's chest.

 

"But you didn't."

 

Izuku's breath hitched.

 

"You possess a highly destructive Quirk, young man. A Quirk that many would say is suited for fighting, not rescuing. Yet, you didn't hesitate. You didn't stop to calculate the odds. Your body moved before you even had a chance to think. You analyzed the villain's weakness, you minimized the collateral damage, and you plunged into the fire to save your brother's life."

 

Tears pricked the corners of Izuku's eyes. For his entire life, his Quirk had been compared to Katsuki's. He was the tactical one, the smart one, but Katsuki was the powerhouse. Katsuki was the natural-born hero. To have All Might—the absolute pinnacle of heroism—look past the raw power of Explosion and validate Izuku's heart was overwhelming.

 

"There are stories about every great hero," All Might continued, his voice echoing in the quiet park. "How they became great. Most of them have one thing in common. Their bodies moved before they had a chance to think."

 

All Might smiled, a genuine, warm expression that transcended his frail form. "You can become a hero. Not just a hero, Izuku Bakugo. You can become the next Symbol of Peace."

 

Izuku fell to his knees, the tears finally spilling over, a sob tearing from his throat. He bowed his head, crying into his hands, the validation washing over him like a tidal wave.

 

All Might placed a gentle hand on Izuku's shoulder. "I am proposing something incredible, young man. I want to pass my Quirk on to you."

 

Izuku’s head snapped up, tears flying. "Pass... your Quirk? But Quirks are genetic! You can't just hand them out like trading cards! It defies all known biological science!"

 

"My Quirk is an exception," All Might explained, chuckling at Izuku's immediate descent into analytical muttering. "It is a power that has been passed down from generation to generation. It is called... One For All."

 

"One... For All?"

 

"Yes. One person cultivates the power, refining it, adding to it, and passes it on to the next. It is the crystallized power of many, a web of voices crying out for salvation, woven together to strike down evil. I am the eighth wielder. And I want you to be the ninth."

 

Izuku stared at his own hands. His palms, slightly scarred from the burns of his own explosive sweat. He already possessed a lethal Quirk. The idea of adding the sheer, cataclysmic power of All Might to his own body was terrifying.

 

"Why me?" Izuku asked, his voice trembling. "If I take your power... I'll have two Quirks. Kacchan... Kacchan will never forgive me. We promised we would compete for the Number One spot on equal footing. If I have your power, it's not a fair fight."

 

All Might's expression sobered. He knelt down, bringing himself to eye level with the young boy. "True heroism is rarely about fairness, Izuku. The villains will not fight fair. The disasters will not be fair. Your brother will grow into a mighty hero, but a Symbol is something different. A Symbol must bear the weight of the entire world. It requires a heart that prioritizes saving over winning."

 

All Might looked deeply into Izuku's eyes. "I will not force this upon you. It is a grueling path. You will have to lie to the world, to your friends, and to your brother. The secret of One For All must be kept, lest villains target you before you are ready. It will be a lonely burden. But if you accept it, you will have the power to save everyone with a smile."

 

Izuku looked down at the dirt path. He thought about Katsuki. He thought about the fierce, unrelenting pride in his brother's eyes. Katsuki would hate this. Katsuki would see it as a betrayal, an unfair advantage, a spit in the face of their lifelong rivalry.

 

But then Izuku thought about the Sludge Villain. He thought about the terror of watching his brother suffocate. He thought about the countless people in the world who were suffering, who needed a hero who could blow away the darkness and stand unshaken in the storm.

 

Izuku didn't just want to beat Kacchan. He wanted to save the world.

 

Izuku wiped his tears, his jaw setting with a newfound, unbreakable resolve. He looked up, his green eyes burning with a fire hotter than any explosion he had ever created.

 

He stood up, wiping his face, and looked All Might dead in the eye.

 

"I accept," Izuku said, his voice steady, devoid of all hesitation. "I'll do it. I'll bear the burden. I'll become the vessel."

 

All Might's smile returned, broader and brighter than before. "Excellent answer. But do not celebrate yet, young Bakugo! Your body is strong from your training, but to inherit One For All, we must rebuild you from the ground up! A vessel that is not prepared will simply shatter upon receiving the power!"

 

"Shatter?!" Izuku blanched.

 

"Indeed! You have ten months until the U.A. Entrance Exam! Ten months of hell to prepare your body to receive my power! Are you ready, Izuku Bakugo?!"

 

Izuku nodded, a fierce, excited grin breaking across his face. "Yes, sir!"

 

As the sun fully set, casting the park into twilight, a pact was sealed in the shadows. Izuku walked home that night, his mind racing with a million thoughts, a million fears, and an overwhelming sense of destiny.

 

He opened the front door of the Bakugo residence, instantly met with the smell of spicy curry and the sound of his mother yelling at his father about a burnt pot.

 

"Where the hell have you been, Nerd?" Katsuki demanded from the dinner table, a bandage wrapped around his neck where the sludge had cut him. He glared at Izuku, his eyes full of defensive pride. "You better not be expecting a thank you for today. I had it under control."

 

Izuku looked at his twin. The brother he loved, the brother he rivaled, the brother he was now destined to surpass in a way Katsuki could never anticipate.

 

Izuku smiled, a soft, incredibly sad smile that Katsuki couldn't quite decipher.

 

"I know you did, Kacchan," Izuku lied smoothly. "I just wanted to make sure I got my hits in."

 

The path was set. The secret was buried. And the race to the top was about to become infinitely more explosive.

 

The smell of Dagobah Municipal Beach Park was an unholy amalgamation of decaying seaweed, rusted iron, and stagnant seawater. For years, the ocean currents had treated this stretch of coastline as a dumping ground, and the local populace had eagerly followed suit. Mountains of discarded appliances, rotting tires, and jagged scrap metal stretched as far as the eye could see, effectively burying the sand beneath a monument to societal neglect.

 

Izuku Bakugo stood at the edge of the paved boardwalk, the early morning ocean breeze violently whipping his untamable, green-tinted ash-blonde hair around his face. He wore a plain white t-shirt and dark sweatpants, a pair of thick, heavy-duty work gloves clutched in his right hand.

 

Standing beside him, looking entirely out of place amidst the urban decay, was the skeletal, coughing form of Toshinori Yagi—the man the world knew as All Might.

 

"Holy crap," Izuku muttered, his wide green eyes scanning the sheer volume of trash. "I knew it was bad, but... this is a logistical nightmare. The sheer tonnage of metal alone..."

 

"A hero volunteers to clean up the messes that others ignore!" All Might declared, blood dribbling slightly from the corner of his mouth before he casually wiped it away. "This, young Bakugo, is your crucible!"

 

Izuku pulled a fresh notebook from his pocket—Hero Analysis for the Future, Vol. 14—and began scribbling furiously. "Right. Okay. So, to properly prepare my body for One For All, I need to increase my overall muscle mass, specifically my core and upper body strength, to prevent the kinetic feedback from shattering my skeletal structure. My Quirk, Explosion, already requires a high degree of wrist and forearm density to withstand the recoil, but the sheer force of your Quirk requires a full-body structural overhaul. If I categorize the debris by weight and drag coefficient..."

 

All Might sweatdropped, watching the boy mutter at a speed that defied human linguistics. He reached out, gently but firmly plucking the notebook from Izuku's hands.

 

"No notebooks, my boy," All Might said, reaching into his oversized pocket and pulling out a thick, bound stack of papers. "I have already done the calculating for you! Behold! The 'Aim to Pass: American Dream Plan'!"

 

Izuku took the thick packet, flipping through the pages. His eyes widened. It wasn't just a workout routine; it was a microscopic breakdown of his entire life for the next ten months. Sleep schedules, caloric intake, macro-nutrient ratios, stretching regimens, and a meticulously charted map of the beach, dictating exactly which piles of trash to move on which days.

 

"You tailored this... perfectly," Izuku breathed in awe. "You even accounted for the caloric burn of my daily quirk usage!"

 

"Of course I did!" All Might puffed out his chest, transforming into his muscle form in a burst of steam. "I am a teacher now, after all! Your body is already accustomed to the physical strain of your explosions, which gives you a magnificent head start! But to inherit One For All, you must transform your body from a sports car into an armored tank! We have ten months until the U.A. Entrance Exam! You must clear this entire beach by then!"

 

Izuku looked from the towering hero to the towering piles of trash. The task was Herculean. It was borderline impossible for a fourteen-year-old boy, even one with a powerful quirk.

 

But Izuku thought of the Sludge Villain. He thought of Katsuki gasping for air. He thought of the promise he had made beneath the setting sun.

 

Izuku pulled the heavy-duty work gloves onto his hands, securing the velcro straps around his wrists. He cracked his knuckles, a small, involuntary spark of orange light popping from his fingertips.

 

"Let's get to work," Izuku said.

 

 

 

The first month was absolute agony.

 

Izuku was no stranger to physical exertion. Growing up as the twin brother and primary sparring partner to Katsuki Bakugo meant that Izuku had spent the better part of a decade dodging, weaving, and fighting. His stamina was excellent, his reflexes were sharp, and his pain tolerance was uncommonly high.

 

But dragging a water-logged, rust-welded refrigerator across fifty yards of shifting, uneven sand was a different kind of hell altogether.

 

His muscles screamed. His hands, usually calloused only at the fingertips and palms from his explosions, blistered and bled beneath his work gloves. Every night, he would stumble into the Bakugo household, smelling like a rancid mixture of ocean water, tetanus, and icy-hot muscle rub.

 

"What the hell is that smell?!" Katsuki yelled from the living room sofa one Tuesday evening, pausing his video game as Izuku dragged himself through the front door. "Did you roll in a dead whale, Nerd?"

 

"Just... just taking a new route home, Kacchan," Izuku lied, his voice practically trembling with exhaustion. He leaned heavily against the wall, trying to pry his sneakers off his aching feet. "Found a stray cat near the docks. Tried to catch it. Fell in some garbage."

 

Katsuki paused his game, his red eyes narrowing suspiciously. He stood up, walking over to the entryway. He looked Izuku up and down. Izuku was covered in dirt, his uniform pants were ripped at the knee, and there was a dark, purpling bruise blooming on his left forearm where a rogue television set had clipped him earlier that afternoon.

 

"A stray cat," Katsuki repeated, his voice dangerously flat. "A stray cat gave you a bruise the size of a grapefruit and made you smell like a junkyard?"

 

"It was a very aggressive cat," Izuku smiled weakly.

 

"Don't lie to me, Deku," Katsuki snapped, grabbing Izuku by the collar of his uniform jacket.

 

Izuku flinched, not out of fear, but out of a sudden, sharp ache in his overtaxed shoulders. Katsuki felt the flinch. He immediately let go, taking a half-step back, though his scowl deepened into something resembling an angry pout.

 

"Whatever," Katsuki scoffed, crossing his arms. "Just wash the stink off. I've been waiting for two hours. We're supposed to be sparring at Ground Zero right now. My sweat glands are itching."

 

Izuku closed his eyes, a wave of profound guilt washing over him. This was the hardest part. The physical pain of the beach was nothing compared to the emotional toll of lying to his brother. For their entire lives, their routine had been unbreakable. School, analyze, spar, repeat. The rivalry was the core of their relationship. By breaking that routine, Izuku was inadvertently breaking their bond.

 

"I can't tonight, Kacchan," Izuku said softly, looking at the floor. "I have extra studying to do. My modern literature grades are slipping, and U.A. has a notoriously difficult written exam. I need to hit the books."

 

The silence in the hallway was deafening.

 

Katsuki stared at Izuku, his jaw clenching so tightly a muscle ticked in his cheek.

 

To Izuku, it was just an excuse to go to sleep so he could wake up at 4:00 AM and move more trash. But to Katsuki, it was a massive, neon insult. Katsuki translated everything through the lens of strength and competition. If Izuku was dodging sparring sessions, it meant Izuku no longer thought Katsuki was worth fighting. It meant Izuku thought he was already better.

 

"Right," Katsuki said, his voice dropping an octave, losing its usual fiery bravado and becoming something cold, sharp, and deeply resentful. "You're too busy for me. Got it."

 

"Kacchan, that's not—"

 

"I said, got it, Nerd," Katsuki snarled, turning his back on Izuku and stomping up the stairs. "Don't come crying to me when you fail the physical exam because you spent all your time reading poetry!"

 

Izuku watched his brother disappear into his bedroom, the door slamming shut with a concussive bang that rattled the picture frames in the hallway. Izuku slumped against the wall, sliding down until he hit the floor, burying his face in his aching hands.

 

I'm sorry, Kacchan, Izuku thought, fighting back tears of exhaustion. Just wait ten months. Once I have the power, I'll tell you everything. I promise.

 

 

 

By month five, the tension in the Bakugo household was thick enough to cut with a chainsaw.

 

Mitsuki and Masaru noticed it, of course. It was impossible not to. The explosive, shouting, roughhousing dynamic of the twins had vanished, replaced by a cold war of silent glares and deliberate avoidance.

 

They ate dinner in total silence. Katsuki would inhale his spicy curry, glaring daggers at Izuku, before abruptly leaving the table to go do high-intensity interval training in the backyard. Izuku would sit there, mechanically shoveling food into his mouth, his eyes constantly drooping shut, his body vibrating with an exhaustion so deep it felt cellular.

 

One weekend afternoon, Katsuki was in the garage, aggressively wrapping his wrists with athletic tape. He was preparing to head to Ground Zero alone. He hated it. Hated the silence of the quarry without Izuku there to counter his blasts. Hated the feeling that he was standing still while Izuku was off doing some secret, solitary training.

 

Because Katsuki wasn't an idiot. He knew Izuku wasn't just "studying."

 

Katsuki had noticed the changes. Izuku’s shoulders were getting broader. The fabric of his uniform shirts pulled tightly across his chest and biceps. When Izuku reached for the salt at the dinner table, Katsuki saw the new, thick callouses on his palms—not the smooth, burn-scarred callouses from explosions, but rough, jagged callouses from gripping heavy objects.

 

Izuku was getting stronger. Visibly stronger. And he was doing it without Katsuki.

 

The garage door opened. Izuku walked in, wearing his workout clothes, carrying a trash bag full of empty water bottles. He stopped dead when he saw Katsuki.

 

"Oh. Hey, Kacchan," Izuku said cautiously.

 

Katsuki finished tying the tape with his teeth, spitting the loose end out. He stood up, walking slowly toward Izuku. He stopped inches from his brother's face, towering over him ever so slightly, his crimson eyes burning with a mixture of betrayal and fury.

 

"What the hell are you doing, Deku?" Katsuki demanded, his voice dangerously low.

 

"I'm... taking out the recycling?"

 

"Don't play dumb with me!" Katsuki suddenly shoved Izuku back against the garage wall. It wasn't a playful shove; it was hard, fueled by genuine anger. "You think I'm blind?! You're sneaking out before dawn. You come back smelling like a sewer. You're putting on muscle mass. You're training without me."

 

Izuku swallowed hard, keeping his hands down. "I'm just trying a different regimen, Kacchan. It's not a big deal."

 

"It is a big deal!" Katsuki roared, small pops of nitroglycerin igniting on his taped knuckles. "We made a vow! We're supposed to race to the top! How am I supposed to crush you if you're hiding your moves from me?! Are you looking down on me?! Do you think you don't need to practice against me anymore?!"

 

"No! Of course not!" Izuku pleaded, his green eyes wide and earnest. "Kacchan, you're the strongest person I know! I'm not looking down on you! I'm just... I'm working on my weaknesses!"

 

"Your weakness is that your explosions lack concussive punch!" Katsuki countered fiercely. "And the only way to fix that is by fighting me! So why are you running away?!"

 

Izuku clenched his jaw. He wanted to scream the truth. He wanted to tell Katsuki about One For All, about the Symbol of Peace, about the immense burden he was carrying. But All Might’s warning echoed in his head. The secret must be kept. It will be a lonely burden.

 

"I can't explain it right now, Kacchan," Izuku said, his voice dropping to a stubborn whisper. "But I promise you, when the Entrance Exam comes... I'll show you exactly what I've been doing."

 

Katsuki stared at him, searching Izuku's face for a lie. He found only an immovable, rock-solid determination. It was a look Izuku had never directed at him before.

 

Katsuki slowly stepped back, releasing Izuku. He turned away, picking up his gym bag.

 

"Fine," Katsuki spat, his voice laced with venom. "Keep your damn secrets, Nerd. But understand this: whatever little trick you're working on, it won't be enough. I'm going to obliterate the Entrance Exam. I'm going to take first place, and I'm going to leave you choking on my smoke."

 

Katsuki walked out of the garage, the door slamming shut behind him.

 

Izuku slid down the wall, exhaling a shaky breath. The rift between them was now a chasm. But Izuku couldn't focus on that now. He had three months left, and a quarter of a beach still covered in steel.

 

 

 

Month Ten. The final day.

 

The sun was just beginning to peek over the horizon, painting the sky in brilliant strokes of pink and gold, when Toshinori Yagi arrived at Dagobah Beach.

 

He stepped out of his truck, a steaming cup of coffee in hand, ready to bark out his morning encouragements. But as he looked out over the shoreline, the coffee cup slipped from his grasp, shattering against the pavement.

 

The beach was immaculate.

 

Not a single tire. Not a single rusted pipe. Just pristine, golden sand stretching out to meet the gently lapping waves of the ocean.

 

And there, standing atop the final, massive pile of collected scrap metal, perfectly silhouetted against the rising sun, was Izuku Bakugo.

 

Izuku didn't have his shirt on. His torso, once lean and entirely unnoteworthy, was now corded with dense, incredibly defined muscle. He was sweating profusely, his chest heaving as the ocean breeze cooled his skin.

 

He looked out at the horizon, realizing what he had accomplished. The sheer impossibility of it. He had pushed his body past its limits a thousand times over, driven by a singular, unyielding will to prove himself worthy.

 

Izuku threw his head back and unleashed a primal, echoing roar at the sky.

 

It was a cry of triumph, of pain, of ten months of pent-up frustration and exhaustion finally releasing into the ether.

 

All Might instantly transformed into his muscle form, leaping from the boardwalk and landing softly on the sand below the scrap pile. "OH MY... GOODNESS!" All Might boomed, pure awe in his voice.

 

Izuku looked down, panting. Suddenly, his legs gave out. The adrenaline faded, and gravity took over. Izuku tumbled backward off the pile of scrap, plummeting toward the sand.

 

Before he could hit the ground, All Might was there, catching the boy in his massive arms.

 

"You truly are a madman, young Bakugo!" All Might laughed, immense pride radiating from his smile. "You didn't just complete the plan, you went above and beyond! You cleared the entire beach! You created a vessel far stronger than I ever anticipated!"

 

Izuku looked up at his mentor, a weak, exhausted smile on his face. "I wanted... to make sure... I wouldn't shatter. I had to be perfect. Kacchan wouldn't settle for less... and neither can I."

 

All Might set Izuku down gently on his feet. The pro hero looked at the boy—really looked at him. The fire in Izuku’s eyes was identical to the fire that burned within All Might’s own chest.

 

"You have earned it, my boy," All Might said, his voice dropping into a solemn, reverent tone. "It is time to receive your reward. The crystallized power of the past. One For All."

 

Izuku stood up straight, his heart hammering against his ribs. This was it. The moment of inheritance. He imagined a brilliant, glowing light transferring from All Might's chest into his own. He imagined a solemn vow, a passing of the torch in a blaze of glory.

 

All Might reached up, plucked a single, golden strand of hair from his bangs, and held it out to Izuku.

 

"Eat this."

 

Izuku blinked. The wind blew silently across the beach.

 

"...What?" Izuku deadpanned.

 

"To inherit the Quirk, you must ingest some of my DNA!" All Might explained enthusiastically, thrusting the hair closer to Izuku's face. "It doesn't matter what it is, as long as it gets into your system! The stomach acid will break it down and bind the Quirk factor to your own!"

 

Izuku stared at the hair, his face scrunching up in profound disgust. "That is... logically sound, but completely unheroic and deeply unsanitary."

 

"There's no time for aesthetics! The Entrance Exam starts in three hours! Down the hatch!"

 

Izuku groaned, taking the hair. He pinched his nose, closed his eyes, and swallowed it dry. He gagged violently, coughing and pounding his chest.

 

"Excellent! Now, hurry home, shower, and get to U.A. High! The Quirk will take a few hours to metabolize, so you won't feel it right away, but it will be there when you need it!"

 

Izuku nodded, his stomach doing uncomfortable backflips. "Right. The Exam. I'm ready."

 

 

 

The morning of the U.A. Entrance Exam, the Bakugo household was unusually quiet.

 

Mitsuki had made a massive breakfast of eggs, rice, and grilled fish, but Katsuki and Izuku ate in near silence. The air crackled with unspoken tension. They were both dressed in their Aldera Junior High uniforms, their bags packed, their expressions utterly stoic.

 

Masaru cleared his throat, looking between his two sons. "So... today's the big day. Are you both feeling confident?"

 

Katsuki stood up, his chair scraping loudly against the floor. He slung his bag over his shoulder. "I'm going to get the highest score in the history of the school," he stated flatly, not looking at anyone. He walked to the front door, slipping his shoes on.

 

Izuku finished his rice, stood up, and bowed to his parents. "Thank you for the meal. I'll do my best."

 

Mitsuki watched them go, a worried frown creasing her forehead. "Those two... they're going to tear that school apart."

 

"Let's just hope they don't tear each other apart first," Masaru sighed.

 

The walk to U.A. High was agonizing. They walked side-by-side, but they might as well have been on different planets. Katsuki radiated a fierce, aggressive aura, his hands jammed deep into his pockets, his eyes fixed dead ahead. Izuku was practically vibrating with nervous energy. He kept flexing his fingers, waiting to feel the mythical power of One For All, but all he felt was his own, familiar sweat glands and the ache of his overworked muscles.

 

What if it didn't work? Izuku panicked internally. What if my stomach acid destroyed the DNA entirely? What if my existing Quirk factor rejected the new one?

 

They arrived at the front gates of U.A. High School.

 

The building was a colossal, H-shaped monument to heroism, gleaming in the morning sun. Hundreds of aspiring heroes were flocking through the gates, a sea of different uniforms, quirks, and anxious faces.

 

"Out of my way, extras," Katsuki growled, shoving past a group of taller students. He didn't look back to see if Izuku was following.

 

Izuku took a deep breath, stepping onto the pristine pavement of the campus. He was so busy staring up at the massive glass windows, running the probabilities of the exam in his head, that he completely failed to notice his own feet tangling together.

 

Izuku tripped, plunging face-first toward the concrete.

 

Crap! I'm going to break my nose before the exam even starts! Izuku thought. He instinctively raised his hands, preparing to fire a tiny burst of explosion to right himself.

 

But before he could ignite his sweat, he felt a sudden weightlessness.

 

He froze, suspended mid-air, inches from the pavement.

 

"Are you okay?"

 

Izuku looked up. Standing next to him was a girl with a round, cheerful face, large brown eyes, and permanent pink blush on her cheeks. She had one hand lightly touching his backpack.

 

"It's my Quirk," the girl smiled brightly, releasing him so he dropped gently onto his feet. "Sorry I used it on you without asking, but it would be bad luck to fall right before the exam, wouldn't it?"

 

Izuku, completely unused to interacting with girls who weren't terrified of his and his brother's reputation, blushed furiously. "O-Oh! Um! Yes! Thank you! That was a highly efficient application of a zero-gravity quirk! Very low kinetic feedback!"

 

The girl blinked, a bit overwhelmed by the sudden analysis, but she laughed brightly. "I'm Uraraka Ochaco! Let's both do our best today!" She gave him a wave and jogged off toward the auditorium.

 

"I just talked to a girl," Izuku whispered to himself, awestruck.

 

"You didn't talk to her, you babbled like a moron," a harsh voice barked.

 

Izuku flinched. Katsuki had stopped a few yards ahead, looking back with a sneer. "Stop tripping over your own feet and get moving, Deku. You're embarrassing me."

 

"Coming, Kacchan!"

 

 

 

The orientation in the massive auditorium was a sensory overload.

 

The Voice Hero, Present Mic, stood on the stage, projecting his voice at a volume that rattled the teeth in Izuku’s skull. Izuku, sitting next to Katsuki, was furiously taking notes on the exam layout, muttering under his breath about the point system and the distribution of the villain robots.

 

"Shut up," Katsuki hissed, glaring at him. "Your muttering is giving me a migraine."

 

"Sorry," Izuku whispered, quickly capping his pen.

 

Present Mic explained the practical exam. It was a massive urban mock-battle. Examinees would be placed into different replica cities and tasked with destroying villain robots to earn points. One-pointers, two-pointers, and three-pointers.

 

Suddenly, a tall, severe-looking student with glasses stood up in the middle of the auditorium, chopping his hand through the air.

 

"Excuse me! I have a question!" the boy declared loudly. "On the printout, there are four types of villains! If this is a misprint, then U.A., the most prominent school in Japan, should be ashamed of that foolish mistake! Furthermore, you two behind me!"

 

The boy pointed directly at the Bakugo twins.

 

"The one with the unruly hair has been muttering this entire time, and the blonde one is sitting with his feet on the desk! If you are here on a pleasure trip, then you should leave immediately!"

 

The auditorium went dead silent.

 

Izuku shrank down in his seat, embarrassed.

 

Katsuki did not.

 

Katsuki slowly took his feet off the desk. He leaned forward, resting his elbows on his knees, and fixed the bespectacled boy with a stare so lethally aggressive that the temperature in the room seemed to drop.

 

"Listen here, Four-Eyes," Katsuki growled, his voice carrying perfectly through the silent hall. "I'll sit however the hell I want. And if you point at my brother again, I'll blow those glasses straight through the back of your thick skull."

 

The bespectacled boy stiffened, thoroughly intimidated, but tried to maintain his rigid posture. "S-Such barbaric behavior! You are unsuited for U.A.!"

 

"We'll see who's unsuited when I double your score," Katsuki sneered.

 

"Okay, okay, settle down, listeners!" Present Mic intervened quickly, sensing the imminent violence. He explained that the fourth robot was a Zero Pointer—an obstacle meant to be avoided.

 

As the orientation concluded, the examinees were directed to board buses to their assigned testing centers.

 

Izuku looked at his ticket. Test Area B.

 

He looked at Katsuki's ticket. Test Area A.

 

"They split us up," Izuku noted, a sinking feeling in his stomach. They always fought together. Even when they were competing against each other, they fed off each other's rhythm.

 

"Good," Katsuki said sharply, standing up. "Means you won't get in my way, and I won't end up carrying you."

 

Without another word, Katsuki walked toward his bus.

 

Izuku watched him go, his heart heavy. I'm not going to need carrying, Kacchan. I'm going to prove it to you.

 

 

 

Test Area A.

 

The gates of the mock city opened. Before Present Mic could even finish screaming "START!", Katsuki Bakugo was already a streak of orange fire rocketing into the urban sprawl.

 

He was a force of absolute nature.

 

"DIE!" Katsuki roared, launching himself over the hood of an abandoned car. He slammed his palms into the chassis of a three-pointer robot. A concussive blast of sheer, unadulterated force shattered the robot's armor, sending metal plating raining down like shrapnel.

 

He didn't stop. He used the recoil of the blast to propel himself backward, spinning mid-air, and firing two precise blasts that decapitated a pair of two-pointers.

 

The other examinees in Area A could only watch in stunned silence as explosions echoed relentlessly through the streets. Katsuki was a one-man army, his crimson eyes locked on his targets, his movements a beautiful, terrifying dance of violence and agility.

 

"Forty-five points!" Katsuki laughed maniacally, landing gracefully on the roof of a bus, his hands smoking. "Come on! Is that all this elite school has got?!"

 

In the dark observation room hidden deep within U.A., the pro-hero faculty watched the monitors.

 

"Examinee Katsuki Bakugo," a scruffy man in a sleeping bag murmured, his tired eyes tracking the blonde boy's path of destruction. "Quirk: Explosion. High offensive power, excellent battle instincts. He's not just blowing them up; he's using the recoil to eliminate his blind spots. He's terrifyingly competent."

 

"He's got a bad attitude, though," the heroine Midnight noted, twirling a whip around her finger. "Very villainous."

 

"Attitude can be corrected," the man replied. "Skill like that is rare."

 

 

 

Test Area B.

 

Izuku Bakugo stood in the center of the street, breathing heavily.

 

He had twenty-eight points. It was a respectable score, but it wasn't enough. He needed more.

 

His style was vastly different from Katsuki's, and the strain was starting to show. Izuku darted down an alleyway, spotting a group of three two-pointers blocking the exit.

 

He didn't charge them head-on. Izuku clapped his hands together, regulating his sweat to a low burn. "Smokescreen!"

 

A thick, blinding cloud of white smoke filled the alley. The robots’ optical sensors whirred, unable to lock onto a target.

 

Izuku used the cover of the smoke. He fired a series of rapid micro-explosions from his fingertips, bouncing himself off the alley walls like a pinball, gaining altitude and speed. He emerged from the smoke directly above the robots.

 

"Armor Piercing!" Izuku yelled, thrusting his right hand downward. A concentrated, lance-like blast of heat shot from his palm, slicing cleanly through the neck joint of the first robot, melting the circuitry instantly.

 

He landed on the falling robot, using it as a springboard, and fired two more precise shots into the visual sensors of the remaining robots, blinding them permanently, before kicking them over.

 

Thirty-four points, Izuku calculated, rolling onto the pavement.

 

He winced, grabbing his right wrist. The athletic tape beneath his gloves was already scorching hot. He had been spamming his precision blasts, and without Katsuki’s massive concussive force to rely on, Izuku was having to work twice as hard to destroy the heavier armor of the three-pointers.

 

I'm tired, Izuku realized, his muscles screaming. The ten months of beach cleanup... my body is conditioned, but I didn't give it enough time to rest before the exam.

 

He still hadn't felt One For All. He had tried, briefly, to summon the immense power All Might had described, but nothing happened. He was fighting on his own strength alone.

 

Suddenly, the ground began to tremble.

 

It wasn't a minor tremor. It was a localized earthquake. The windows of the mock buildings shattered from the sheer vibration.

 

Izuku looked up, his green eyes widening in absolute horror.

 

Rising above the skyline of the mock city, dwarfing the buildings around it, was the Zero Pointer. It was a behemoth of steel and treads, an impossible titan that blocked out the sun.

 

"Less than two minutes remaining!" Present Mic's voice blared over the loudspeakers.

 

Panic erupted in the streets. The examinees, heroes-in-training who had been bravely fighting a moment ago, broke and ran in the opposite direction.

 

"Run away!"

"That thing is insane!"

"It's a monster!"

 

Izuku took a step back, his instincts screaming at him to flee. The Zero Pointer raised a massive, hydraulic fist and brought it down on a building, obliterating the structure and sending a shockwave of debris sweeping down the street.

 

Izuku covered his face against the dust. Tactically, there's no reason to fight it. It's worth zero points. Retreat is the only logical option.

 

He turned to run.

 

"Ow... my leg..."

 

The voice was faint, barely audible over the grinding of the colossal treads, but Izuku's ears caught it.

 

He stopped. He turned back.

 

Through the settling dust, near the path of the advancing behemoth, was Uraraka. She was trapped. A massive piece of concrete from the destroyed building had fallen, pinning her leg to the street. She was trying to use her Quirk to lift it, but she was past her weight limit, coughing violently, tears streaming down her face.

 

The Zero Pointer's treads were rolling directly toward her.

 

In that fraction of a second, the analytical part of Izuku's brain shut off entirely. The calculations, the point systems, the fear—it all vanished.

 

His body moved on its own.

 

Izuku sprinted toward the giant robot. He didn't know what he was going to do. His explosions, even at maximum output, were like firecrackers against a battleship. He couldn't dent that armor.

 

I need power. I need more power! Izuku screamed internally, his heart hammering against his ribs. ALL MIGHT!

 

As if answering the desperate cry of his soul, something deep within Izuku’s core snapped.

 

It felt like a dam bursting open. A geyser of pure, unadulterated, incandescent energy erupted from the center of his chest. It rushed through his veins like liquid fire, tearing through his muscles, filling every single cell in his body with an impossible, overwhelming strength.

 

Red, glowing veins pulsed rapidly up his neck and across his face. Sparks of brilliant, golden lightning began to crackle and arc aggressively around his body, intermingling fiercely with the orange, sparking ignition of his nitroglycerin sweat.

 

In the observation room, All Might leapt out of his seat, gripping the railing. "He's doing it... but what is that lightning?!"

 

"Is that a secondary Quirk activation?!" Aizawa demanded, his eyes widening. "I thought his file said Explosion!"

 

Down in the street, Izuku didn't care about the lightning. He didn't care about the pain that was suddenly flaring in his muscles, a warning that they were tearing under the sheer pressure of the power.

 

He reached Uraraka. He didn't stop to help her up. He had to stop the threat.

 

Izuku planted his feet, crouching low. He focused One For All into his legs, and simultaneously ignited his sweat glands in his palms, aiming them at the ground.

 

FUSION: EXPLOSIVE OVERDRIVE!

 

Izuku triggered his Quirk and leapt at the exact same time.

 

The resulting launch was cataclysmic. A massive crater instantly formed in the street, shattering the asphalt into dust. A boom echoing like a thunderclap shattered every remaining window in a two-block radius.

 

Izuku broke the sound barrier.

 

He rocketed upward, leaving a trail of smoke, fire, and golden lightning in his wake. He cleared the height of the buildings in a millisecond, ascending until he was face-to-face with the massive head of the Zero Pointer.

 

Time seemed to slow down.

 

Izuku pulled his right arm back. He channeled one hundred percent of One For All into his right arm. The muscles bulged, tearing the sleeve of his uniform shirt. But his body, reacting to the immense kinetic energy and heat, instinctively did what it had trained to do his entire life. It primed his sweat glands.

 

The nitroglycerin in his right palm ignited just as he threw the punch.

 

"DETROIT..."

 

Izuku’s fist slammed into the solid steel face of the behemoth, and his palm detonated simultaneously.

 

"...SMASH!"

 

The fusion of All Might's pure kinetic wind pressure and Katsuki-level concussive explosive force created an impact of biblical proportions.

 

The explosion was blinding. A massive sphere of fire and golden energy erupted in the sky. The sheer force of the punch completely caved in the face of the Zero Pointer, rippling down its metallic spine. The robot didn't just break; it completely buckled, violently imploding backward under the sheer, impossible pressure of the strike.

 

The shockwave blasted through the mock city, a hurricane of wind and heat that blew examinees off their feet from three streets away.

 

In the observation room, the monitors whited out for three full seconds. The seasoned pro-heroes stood in stunned, absolute silence.

 

As the smoke cleared in the sky, Izuku began to fall.

 

The adrenaline vanished, replaced by an agony so pure and absolute it stole the breath from his lungs.

 

He looked at his right arm. It was destroyed. The bones were shattered, the skin a mottled, horrifying purple, flopping uselessly in the wind. The sheer force of One For All, compounded by the internal detonation of his own massive explosion, had completely obliterated his limb.

 

He looked at his legs. Both of them were broken, the bones fractured from the sheer launch pressure.

 

He was in freefall, plummeting toward the pavement a hundred feet below, with no way to break his fall. His arms wouldn't move. His quirk was dead.

 

I saved her, Izuku thought, the wind rushing past his ears. But I'm going to die.

 

Suddenly, a sharp slap across his face brought him out of his morbid thoughts.

 

Slap!

 

Izuku stopped falling. He was floating, weightless, inches from the ground.

 

He looked up. Uraraka was suspended on a piece of debris, having floated herself up to catch him. She looked at him with wide, terrified, grateful eyes, her face green with nausea from overusing her quirk. She pressed her hands together.

 

"Release!" she gagged.

 

They both dropped the remaining two feet to the pavement. Izuku hit the ground, screaming in agony as his broken legs took the impact. Uraraka landed beside him, immediately vomiting a rainbow cascade onto the asphalt.

 

"TIME'S UP!" Present Mic's voice echoed through the ruined city.

 

Izuku lay on his back, staring up at the smoke-filled sky. He couldn't move. He was in more pain than he had ever experienced in his life. He had zero points from that robot. He had likely failed the exam. He had destroyed his own body.

 

But as he heard the mechanical groans of the destroyed titan settling in the distance, a small, pained, triumphant smile touched his lips.

 

I did it, Kacchan, Izuku thought before his eyes rolled back and he passed out from the pain. I can compete with you now.
