What if deku was the species of Diamondhead from ben 10

 

 

 

The world is not born equal.

 

That was the harsh, unspoken truth that governed modern society, a lesson most children learned by the time they were four years old. Over a century ago, a baby in Qing Qing City, China, began to radiate a soft, luminescent light, heralding the dawn of a new era. What was once the domain of comic books and fantasy novels rapidly morphed into the everyday reality of the human race. They called them "Quirks." Singularities of genetic evolution that granted abilities ranging from the mundane to the godlike.

 

In the present day, nearly eighty percent of the global population possessed some kind of superhuman trait. Society had adapted, laws were rewritten, and a brand-new profession emerged from the chaos to maintain order and protect the innocent.

 

Heroes.

 

For a young Izuku Midoriya, there was nothing in the universe more magnificent than a Hero. He didn’t care about sports, or video games, or whatever trivial toys the other children at his preschool obsessed over. Izuku cared about Heroes. More specifically, he cared about the Hero. The Symbol of Peace. All Might.

 

In the dimly lit bedroom of the Midoriya apartment, the pale glow of a computer monitor washed over a mop of unruly green hair. Four-year-old Izuku sat inches from the screen, his massive, emerald eyes sparkling with unadulterated awe. In his small hands, he tightly gripped an All Might action figure, his knuckles white with the sheer intensity of his grip.

 

On the screen, a disaster was unfolding. A massive pileup of vehicles, toxic fires raging, and panicked civilians screaming. It was an old video, a staple of internet archives, but to Izuku, it was a holy text.

 

“Can you see him?” the cameraman on the video screamed over the roar of the flames. “He’s already saved a hundred people! That’s crazy! It hasn’t even been ten minutes!”

 

Then, the camera zoomed in. From the wreckage, a towering silhouette emerged. A man built like a mountain, carrying over a dozen people on his back, his arms, and his shoulders. Despite the devastation, despite the smoke and the terror, the man was smiling. A broad, fearless, brilliant smile that seemed to physically push back the darkness.

 

“Fear not, citizens!” the booming voice echoed through the cheap computer speakers, vibrating in Izuku’s chest. “Hope has arrived. Because I am here!”

 

Izuku let out a breathless giggle, his eyes tearing up from the sheer emotion of the moment. He threw his arms up, mimicking the hero’s iconic pose. "He's so cool!" Izuku whispered to himself, the words a reverent prayer. "When I get my Quirk, I'm gonna be just like him. I'm gonna save everyone with a smile!"

 

He waited for his Quirk with the agonizing impatience only a child could muster. Four years old was the standard benchmark. His mother, Inko, could pull small objects toward her with a mild telekinetic Quirk. His father, Hisashi, who worked overseas, could breathe fire. Izuku spent hours trying to inhale deeply and blow out flames, or staring at his All Might figure, willing it to float into his hand.

 

Nothing happened.

 

But Izuku remained optimistic. After all, his best friend, Katsuki Bakugo, had just manifested his Quirk last week. And what a Quirk it was.

 

Katsuki—or "Kacchan," as Izuku affectionately called him—had always been the leader of their small playground group. He was loud, confident, and possessed a natural aptitude for almost everything he tried. When his Quirk manifested, it was like the universe had officially crowned him king. He could sweat a nitroglycerin-like substance from his palms and ignite it at will. Explosions. A flashy, powerful, undeniable Hero's Quirk.

 

Since that day, the dynamic on the playground had subtly shifted. Katsuki went from a confident child to a worshipped deity among the sandbox set. The preschool teachers praised him, the other children followed him like ducklings, and Katsuki’s ego swelled to match his new firepower.

 

Izuku still followed him, of course, but a small, nagging anxiety had begun to take root in his chest. What if his Quirk wasn't as cool as Kacchan's? What if it took too long to show up?

 

Little did Izuku know, his wait was about to end. And the world as he knew it would never be the same.

 

 

 

The late afternoon sun cast long, golden shadows across the municipal park playground. The air was thick with the humidity of approaching summer, carrying the scent of warm asphalt, pine needles, and the sharp, acrid tang of burnt sugar.

 

That smell was Katsuki Bakugo.

 

"Take that!" Katsuki shouted, thrusting his palms forward. Small, crackling pops echoed across the sandbox like firecrackers. Pop! Pop! Bang! Tiny bursts of orange flame illuminated his fierce, triumphant grin.

 

"Whoa, Bakugo! That’s so cool!" cheered one of the neighborhood boys, a kid with wings sprouting from his back.

 

"Of course it is," Katsuki declared, blowing a wisp of smoke from his fingertips with theatrical arrogance. "It’s an amazing Quirk. The best in the whole world! I’m gonna be the number one hero, even better than All Might!"

 

Izuku watched from the swings, his legs kicking back and forth, a mixture of awe and a strange, hollow sadness in his stomach. He wanted to cheer too, but today, Katsuki was being... rough. The line between playing hero and just being a bully was beginning to blur.

 

Near the edge of the sandbox, a boy named Taku was crying. Taku had a minor Quirk that let him stretch his fingers out like rubber bands. A few minutes ago, Taku had found a shiny, rare beetle in the dirt. Katsuki had demanded it, claiming that as the future Number One Hero, all the best stuff rightfully belonged to him. When Taku refused, Katsuki had shoved him down and snatched the bug jar.

 

"Give it back," Taku sniffled, rubbing dirt from his tear-streaked face.

 

"I told you, extra, you don't deserve it!" Katsuki sneered, holding the jar up to the light. "Besides, what are you gonna do about it? Slap me with your weird, floppy fingers? You're weak."

 

The other kids laughed, eager to stay on Katsuki’s good side.

 

Izuku stopped swinging. His small hands tightened around the rusty chains. His heart pounded against his ribs like a trapped bird. The All Might video flashed in his mind. Fear not, citizens. Hope has arrived.

 

A hero doesn't watch people cry. A hero steps in.

 

Before his brain could process the fear, Izuku’s legs were moving. He hopped off the swing and marched toward the sandbox, his small green sneakers kicking up puffs of dust. He stepped between Katsuki and Taku, throwing his arms out wide to shield the crying boy.

 

"K-Kacchan, stop it!" Izuku's voice trembled, but he stood his ground. "You're making him cry!"

 

Katsuki blinked, surprised. The playground fell silent. The king had been challenged, and by his own loyal shadow, no less.

 

"Huh?" Katsuki’s crimson eyes narrowed, a dangerous glint flickering within them. "Deku. What do you think you’re doing?"

 

'Deku' was a nickname Katsuki had given him a few months ago, reading the kanji of Izuku's name to mean 'one who can't do anything.' It was meant to be an insult, a reminder of Izuku's lack of a Quirk.

 

"Y-You can't just take his stuff, Kacchan," Izuku stammered, his knees knocking together. He swallowed hard, trying to summon even an ounce of All Might’s bravery. "It's mean. I... I won't let you hurt him anymore!"

 

Katsuki’s face darkened. He dropped the bug jar in the sand and took a step forward, raising his hands. Sparks began to dance across his palms, hissing and popping ominously.

 

"You won't let me?" Katsuki scoffed, his voice dropping into a menacing growl. "You don't even have a Quirk, Deku. You're just a weakling. Are you trying to act like a hero? You think you're better than me?!"

 

"No! That's not it!" Izuku protested, backing up slightly, though he kept his arms outstretched, protecting Taku. "But heroes don't bully people!"

 

The word 'bully' snapped something in Katsuki's prideful four-year-old brain. He didn't want to be a villain; he was the hero! And this Quirkless nobody was daring to tell him otherwise in front of his 'fans.'

 

"Shut up!" Katsuki roared. He lunged forward, his right hand drawn back. Sweat ignited on his palm, fueled by a sudden spike of anger and adrenaline. It was a larger explosion than he had ever produced before.

 

Izuku saw the flash of orange light. He saw Katsuki’s furious face. He felt the sudden, intense wave of heat rolling toward him.

 

Time seemed to slow to an agonizing crawl. Izuku squeezed his eyes shut and crossed his arms over his face, bracing for the burning pain, the concussive force, the inevitable agony of the blast.

 

BOOM!

 

The explosion was deafening. A shockwave rippled through the playground, kicking up a massive cloud of sand and smoke. The other children screamed and scrambled backward, covering their ears. Katsuki himself was thrown off balance, skidding backward on his heels, his eyes wide with shock at the sheer power of his own attack.

 

Silence descended on the playground, broken only by the settling of dust and the distant chirp of birds.

 

Katsuki stared at the billowing cloud of grey smoke, his breath hitching. Did I... did I kill him? A sudden, cold spike of genuine panic pierced his anger. He hadn't meant to make an explosion that big. He just wanted to scare him.

 

"Deku?" Katsuki whispered, his voice trembling for the first time in his life.

 

The smoke began to clear, drifting away on the summer breeze.

 

Within the fading haze, a silhouette stood completely still.

 

Izuku hadn't moved. His arms were still crossed over his face, his legs braced in a defensive stance. But something was horribly, beautifully wrong.

 

Where there should have been scorched clothes and burned flesh, there was light. A soft, iridescent, pale-green glow radiated from Izuku’s body. The sunlight caught the edges of his form, refracting in a blinding cascade of prismatic colors.

 

Izuku slowly opened his eyes. He didn't feel any pain. In fact, he felt strangely invigorated. A cool, heavy solidity anchored his bones. He blinked, looking down at his arms.

 

He screamed, but not in pain. It was a high, shrill shriek of utter shock.

 

His skin was gone. Or rather, his skin was no longer skin.

 

From the tips of his fingers to the collar of his shirt, his flesh had transformed into a jagged, translucent, pale-green crystal. It wasn't just a covering; it was him. He could feel the breeze against the faceted surface of his arm. He flexed his fingers, and the crystalline joints shifted flawlessly, sliding against one another with a soft, resonant clink-clink-clink sound, like a wind chime rustling in a gentle gale.

 

Izuku touched his face. His cheeks were hard, smooth, and cold. He looked down at his chest. His clothes were partially singed from Katsuki’s explosion, but the blast had completely exposed his crystalline torso. He was a living, breathing gemstone.

 

The other children stared in horrified, awestruck silence. Taku, who was sitting in the sand behind Izuku, scrambled backward, his eyes wide as saucers.

 

Katsuki stood frozen, his jaw slack. The boy he had just blasted with a point-blank, enhanced explosion didn't even have a scratch on him. The blast hadn't just failed to hurt Izuku; it had completely deflected off the sheer density of his new form.

 

"D-Deku?" Katsuki stammered again, pointing a trembling finger. "What... what are you?"

 

Izuku looked at his crystalline hands, turning them over. The sunlight danced across the facets of his knuckles, casting green reflections across the sand. A massive, beaming smile broke across his hard, geometric face. The fear from moments ago vanished, replaced by an overwhelming, intoxicating wave of euphoria.

 

"My Quirk..." Izuku whispered, the sound vibrating strangely in his throat, carrying a faint, musical resonance. He looked up at Katsuki, his emerald eyes shining brighter than the crystal he was made of.

 

"Kacchan! I got my Quirk!" Izuku cheered, leaping into the air. When he landed, his heavy, crystalline weight hit the sand with a deep thud, leaving distinct indentations. "I'm not Quirkless! Look at me!"

 

Katsuki didn't know how to respond. His reality, his absolute certainty that he was the strongest, had just shattered against the unbreakable wall of Izuku's new body. Katsuki grit his teeth, a complicated mix of relief that he hadn't killed his friend, and intense, burning jealousy pooling in his gut.

 

Before anyone could say another word, a frantic voice pierced the air.

 

"Izuku!"

 

Inko Midoriya came sprinting across the park lawn, dropping a bag of groceries on the grass in her panic. She had heard the explosion from the sidewalk and recognized the playground. She pushed past the staring children, her face pale with terror.

 

"Izuku, baby, are you okay? I heard a blast, I—"

 

Inko froze.

 

She stared at the green, glowing, jagged little golem standing in the middle of the sandbox. He was wearing Izuku’s red shoes and Izuku’s singed yellow t-shirt, and he possessed Izuku’s large, expressive eyes, but the rest of him was utterly alien.

 

"Mom!" Izuku chirped, running toward her. His movements were slightly clunky, getting used to the new weight of his limbs, and every step sounded like a sack of heavy marbles settling. "Mom, look! Kacchan used his explosion on me, and then I turned into this! I have a Quirk!"

 

Inko’s knees gave out. She dropped to the grass, her hands flying over her mouth as tears welled in her eyes. "Izuku? Oh my god... Izuku, what happened to you? Are you hurt? Are you bleeding?"

 

She reached out, her hands shaking, and touched his cheek. She gasped, pulling her hand back instantly. "You're so cold! And hard!"

 

"I don't hurt anywhere, Mom!" Izuku assured her, grabbing her hand with his own crystal one. "Actually, I feel really, really strong! Like All Might!"

 

Inko stared into her son's eyes, seeing the pure, unadulterated joy radiating from him. He wasn't crying. He wasn't hurt. He had finally gotten the Quirk he had been praying for every night. But as a mother, looking at her soft, squishy little boy who was now made of jagged, unbreakable stone, a profound sense of anxiety washed over her.

 

"We..." Inko swallowed hard, trying to keep her voice steady. "We need to go to the doctor, Izuku. Right now."

 

 

 

Dr. Tsubasa’s clinic in the Musutafu medical district was usually a quiet, routine place. Children came in, took an X-ray to check for the extra joint in the pinky toe, demonstrated a mild telekinesis or fire-breathing ability, and went home.

 

Today was not a routine day.

 

Dr. Tsubasa, a bald, portly man with thick goggles and a formidable mustache, sat behind his desk, staring at the medical file in front of him. Then, he slowly raised his head to stare at the four-year-old boy sitting on the examination table.

 

Izuku was swinging his legs, the crystal of his calves clinking softly against the metal of the table. He was still entirely encased in the pale-green gemstone.

 

"Well," Dr. Tsubasa began, taking off his goggles and pinching the bridge of his nose. "This is... unprecedented in my career, Mrs. Midoriya."

 

Inko sat in the visitor's chair, wringing her hands anxiously. "Is he okay, Doctor? Is he sick? Will he... will he change back to normal?"

 

Dr. Tsubasa leaned back in his chair, folding his hands over his stomach. "To answer your last question first: no. I highly doubt he will ever 'change back,' Mrs. Midoriya. This is not an Emitter or a Transformation-type Quirk. What your son has is a profound, fundamental Mutant-type Quirk. His very biology has been rewritten."

 

Inko gasped, covering her mouth. Izuku just tilted his head, his crystal skin shifting with the movement.

 

"Let me walk you through the tests we just attempted," Dr. Tsubasa said, pulling up a screen on his computer. "First, we tried to take an X-ray. As you can see..." He turned the monitor. It was just a solid, bright white rectangle. "The radiation cannot penetrate him. His molecular density is staggering. We tried an ultrasound, and the soundwaves simply bounced back, highly distorted by the faceted structure of his epidermis."

 

"Epidermis?" Inko asked. "His skin?"

 

"If you can call it that," the doctor mused, leaning forward, his eyes gleaming with a scientific curiosity that slightly unsettled Inko. "We attempted to draw a blood sample. The standard steel needle broke against his arm. We had to use a diamond-tipped industrial drill bit just to scrape a few micrograms of material from his shoulder. When we analyzed it under an electron microscope, the results were astounding."

 

Dr. Tsubasa tapped a pen on his desk for emphasis. "Human beings are carbon-based lifeforms, Mrs. Midoriya. Your son, as of his Quirk manifestation, is now a silicon-based lifeform."

 

Silence filled the room. Inko stared at the doctor, entirely lost. "Silicon? Like... like computer chips? Or sand?"

 

"Essentially, yes," Dr. Tsubasa nodded. "His organic material has been converted into a highly advanced, ultra-dense, self-replicating crystalline polymer. I've taken the liberty of categorizing his Quirk classification. I'm calling it 'Petrosapien'—roughly translating to 'Living Rock'. Though, 'Living Diamond' might be more accurate given his durability."

 

"But... how does he live?" Inko pleaded, tears threatening to spill over. "Does he have a heart? Lungs? How will he eat? Can he even eat?!"

 

"Mom, I'm hungry right now," Izuku chimed in, rubbing his flat, geometric stomach.

 

Dr. Tsubasa chuckled dryly. "He speaks, he breathes, he expresses hunger. Therefore, his internal systems must still be functioning, albeit in a radically different manner. My hypothesis is that his internal organs are encased deep within a dense, shielded core in his chest, operating on a completely different metabolic process. He absorbs oxygen, but likely requires vastly less than a normal human. As for food, his body probably converts caloric intake directly into the energy needed to sustain and regenerate his crystal mass."

 

"Regenerate?" Inko latched onto the word.

 

"Well, yes. If he is ever damaged, which would take a monumental amount of force, his body would need to repair itself. We will need to monitor his diet carefully. He may require mineral supplements to maintain his structural integrity. Calcium, silicon, iron—perhaps a specialized diet in the future."

 

Dr. Tsubasa rolled his chair closer to Izuku, looking at him as if he were a priceless artifact. "Tell me, young man. How did you feel when the explosion hit you today?"

 

Izuku stopped swinging his legs. He thought about it for a moment. "It was bright. And loud. But... it didn't hurt. At all. It just felt like a warm wind."

 

Dr. Tsubasa nodded slowly, writing a note on his pad. "Incredible. The concussive force and thermal energy of a point-blank explosion, entirely negated. Mrs. Midoriya, you understand what this means, don't you?"

 

Inko looked at her son, seeing the sharp, jagged spikes protruding from his shoulders and the unyielding hardness of his jawline. "It means my little boy is... he's never going to have a normal life."

 

"Normal?" Dr. Tsubasa scoffed slightly. "Mrs. Midoriya, we live in a world of professional Heroes. The average citizen has a Quirk that lets them pull their eyes out of their head or change the color of their hair. Your son..." He pointed his pen directly at Izuku. "Your son has manifested a Quirk that grants him near-invulnerability. He is quite literally a walking tank. If he pursues the path of Heroism, he possesses a foundational durability that most Pro Heroes would kill for."

 

Izuku’s eyes widened. The ambient light in the room seemed to catch inside his pupils, glowing fiercely. "A Pro Hero... I can be a Hero?"

 

"With a body like that?" Dr. Tsubasa smiled, a genuine, albeit clinical, smile. "Young man, you are practically built for it. Just be careful not to break anything in your house. You weigh about three times as much as a normal child your age now, and your edges are remarkably sharp."

 

As they left the clinic and stepped out into the cool evening air, Inko held Izuku's hand. It felt strange. There was no warmth, no soft pulse beneath the skin. Just the smooth, cool, unforgiving texture of polished stone. She gripped it tightly anyway.

 

Izuku, on the other hand, was practically vibrating with excitement. He looked up at the stars beginning to peek through the twilight sky. He had done it. He had a Quirk. An amazing, invincible Quirk. He couldn't wait to go home and tell All Might—or rather, the poster of All Might on his wall—all about it.

 

 

 

The adjustment period over the next few weeks at the Midoriya household was... chaotic.

 

Dr. Tsubasa had not been exaggerating when he warned them about Izuku’s new physical properties. On his first morning waking up with his new Quirk, Izuku had stretched in bed, and his heavy, crystalline fist had accidentally punched straight through the drywall of his bedroom. He hadn't even felt it. He just pulled his arm back, leaving a perfectly Izuku-fist-sized hole in the plaster, and stared at it in bewilderment.

 

Eating was a strange affair. Izuku found that normal food tasted the same, but he had developed sudden, intense cravings for strange things. When Inko caught him happily sucking on a piece of rock salt he found in the pantry like it was a lollipop, she nearly had a heart attack. A frantic call to Dr. Tsubasa confirmed that Izuku’s body was instinctively seeking out minerals to fortify his silicon structure. From then on, mineral supplements and a slightly altered diet became the norm.

 

But the most astonishing discovery came a week after the manifestation.

 

Izuku was in his bedroom, wearing a pair of reinforced sweatpants Inko had bought for him, as his sharp knees had shredded his normal clothes. He was standing in front of his full-length mirror, practicing his hero poses.

 

"I am here!" Izuku whispered fiercely, planting his hands on his hips and puffing out his crystalline chest.

 

He looked at his reflection. He was certainly intimidating, even for a four-year-old. The pale-green crystal of his body was naturally faceted, making him look like a carefully carved sculpture. Two distinct, jagged shards protruded from his upper back, almost like the beginnings of wings, giving him a formidable silhouette.

 

I'm strong, Izuku thought, clenching his fists. I can take Kacchan's explosions. But All Might punches bad guys. How do I punch if I'm made of rocks? Won't I just break them?

 

He raised his right arm, staring at his forearm. It was thick, segmented with lines that allowed him a full range of motion. He tried to imagine his arm as a weapon. Not something to hurt people, but something to stop villains.

 

What if I had a sword? Like a knight! Knights protect people.

 

Izuku focused all of his mental energy on his right arm. He clenched his jaw, squeezing his eyes shut, and imagined his hand stretching, flattening, sharpening.

 

Suddenly, a bizarre sensation washed over his limb. It didn't hurt, but it felt incredibly strange—like a thousand tiny gears shifting and locking into place beneath his skin. There was a loud, resonant sound of scraping crystal, a shhh-clack! that echoed in the quiet room.

 

Izuku opened his eyes.

 

He gasped, stumbling backward and knocking over his desk chair.

 

His right hand was gone. From the elbow down, his forearm had extended and reshaped itself into a massive, wicked-looking, pale-green crystalline blade. It was easily a foot long, double-edged, and tapered to a razor-sharp point. The crystal hummed softly in the light, possessing a deadly, undeniable beauty.

 

Izuku stared at the weapon extending from his own body, his breath hitching. "Whoa..."

 

Slowly, carefully, he swung his arm. The blade cut through the air with a faint whistling sound. He tapped the flat side of the blade against his left palm. It felt just like his normal hand, possessing a tactile sense, but it was solid, unyielding weapon-grade material.

 

"This is..." Izuku’s mind raced. If he could turn his arm into a sword... what else could he do?

 

He focused again, this time imagining a wall. A barrier. Something to protect someone like Taku from an explosion.

 

Shhh-clack!

 

The blade suddenly broadened, the crystal rapidly multiplying and folding outward. Within seconds, his arm had transformed into a large, rectangular crystalline shield, wide enough to cover his entire torso.

 

Izuku laughed aloud, a joyous, ringing sound. He wasn't just made of crystal. He could control it. He was a living weapon, a living shield.

 

He focused hard, trying to return his arm to normal. The crystal retracted, folding back into itself until his small, green-gemstone hand reappeared. He flexed his fingers. Perfect.

 

He immediately scrambled to his desk, picking up a brand-new notebook Inko had bought him. On the cover, he scrawled in clumsy, childlike handwriting: Hero Analysis for the Future: No. 1.

 

He opened to the first page and began to draw a crude, stick-figure picture of himself. He drew a sword on one arm and a shield on the other. Beneath the drawing, he began to list his abilities as best he could understand them.

 

1. Super hard. Doesn't hurt when things hit me.

2. Can make swords and shields.

3. Very heavy.

 

He paused, chewing on the end of his pencil, which he had accidentally snapped in half with his strong grip. He needed a hero name. Something cool. He looked at the green facets of his arm, thinking about what Dr. Tsubasa had said.

 

Petrosapien. Living Diamond.

 

He carefully wrote a single word at the top of the page, circling it in red crayon.

 

DIAMONDHEAD.

 

 

 

The return to preschool the following Monday was an event that would be etched into the minds of the staff and students forever.

 

When Izuku walked through the classroom door, the room descended into utter silence. The children stopped playing with their blocks. The teacher, Miss Aya, dropped a stack of construction paper, the colorful sheets scattering across the floor.

 

Izuku stood in the doorway, wearing a custom-tailored, loose-fitting blue shirt and soft pants that Inko had hastily modified to prevent his sharp edges from cutting through the fabric. But his head, neck, and hands were fully exposed, shining a brilliant, pale green under the fluorescent classroom lights.

 

He walked to his cubby, his heavy footsteps echoing: Thud. Thud. Thud. The crystalline clinking of his joints accompanied every movement.

 

"Good morning, Miss Aya!" Izuku smiled cheerfully, turning to the stunned teacher.

 

"I-Izuku?" Miss Aya stammered, rubbing her eyes as if she were hallucinating. "Is that... is that really you?"

 

"Yep! I got my Quirk!" Izuku announced proudly, puffing out his chest.

 

Whispers erupted across the classroom like wildfire.

 

Is he made of glass?

He looks like a monster!

No, he looks like a robot!

Wow, it's so shiny...

 

From the corner of the room, sitting at a table with his usual entourage, Katsuki Bakugo stared at Izuku. His red eyes were wide, his jaw clenched tight. Ever since the incident at the playground, Katsuki had been in a foul mood. He had barely spoken to anyone, brooding over the fact that his ultimate explosion had done absolutely nothing to the previously Quirkless Deku.

 

Now, seeing Izuku walk in, glowing and confident, something ugly and competitive flared in Katsuki’s chest. He pushed his chair back violently, the wood screeching against the linoleum floor.

 

"Deku!" Katsuki shouted, marching across the room. The other children quickly parted, knowing better than to get in the way of Katsuki’s wrath.

 

Izuku turned, his emerald eyes meeting Katsuki’s furious crimson ones. A week ago, Izuku would have flinched. He would have lowered his head, stammered an apology, and shrunk away.

 

But Izuku didn't flinch. The heavy, unyielding nature of his physical body seemed to have seeped into his spirit. He stood tall, his posture straight, his crystalline jaw set in a relaxed, yet immovable expression.

 

"Hi, Kacchan," Izuku said evenly.

 

Katsuki stopped a few feet away, his fists clenching at his sides. Small, popping sparks danced across his knuckles. "Don't 'Hi Kacchan' me. You think you're hot stuff now just because you got a shiny new skin? You're still Deku! You're still just a pebble in my way!"

 

"I'm not a pebble, Kacchan," Izuku replied, a hint of steel in his young, musical voice. "I'm a Petrosapien. The doctor said so."

 

Katsuki bared his teeth, leaning in close. "I don't care what some doctor said! My explosion Quirk is still the strongest. I can blast right through you if I want to!"

 

Izuku looked at Katsuki, his large eyes devoid of fear. Instead, there was a quiet, profound realization dawning in Izuku’s mind. He remembered the heat of the explosion. He remembered the feeling of absolute invulnerability.

 

"You can try, Kacchan," Izuku said, his voice calm. "But it didn't work last time."

 

The classroom gasped. Miss Aya stepped forward, her hands raised in panic. "Boys, boys, let's not fight! We don't use our Quirks in the classroom—"

 

"Shut up!" Katsuki roared, completely losing his temper. The blatant challenge, the total lack of fear from the boy who used to cower before him, drove him over the edge.

 

Katsuki lunged forward, his right hand drawn back, sweat igniting on his palm. "I'll shatter you into a million pieces, you damn nerd!"

 

"Katsuki, no!" Miss Aya screamed.

 

Izuku didn't run. He didn't even raise his arms to cover his face this time. He simply braced his legs, dropping his center of gravity, and stared dead ahead as Katsuki’s explosive palm slammed squarely into his crystalline chest.

 

BOOM!

 

The explosion rocked the classroom. Papers flew into the air, desks rattled, and a cloud of black, acrid smoke swallowed the two boys. Several children shrieked, huddling under their tables.

 

Miss Aya coughed, frantically waving her hands to clear the air. "Izuku! Katsuki!"

 

As the smoke rapidly dissipated, drawn out by the ventilation system, the scene in the center of the room became clear.

 

Izuku was still standing in the exact same spot. He hadn't moved an inch. His blue shirt had a large, blackened, charred hole burned directly through the center of the chest, exposing the pale-green crystal beneath.

 

The crystal itself wasn't scratched. It wasn't cracked. It was merely glowing a faint, dull red from the intense heat, a glow that was rapidly fading back to its normal, cool green.

 

Katsuki’s hand was still pressed against Izuku’s chest. The blonde boy’s arm was trembling violently. The recoil of his own point-blank explosion against an immovable object had severely jarred his shoulder and wrist.

 

Katsuki slowly looked up, his eyes wide, his pupils constricted in sheer disbelief.

 

Izuku looked down at him. There was no anger in Izuku’s face. Just a quiet, resolute calm.

 

"See, Kacchan?" Izuku said softly, the words carrying a heavy, undeniable weight. "You can't break me."

 

Katsuki ripped his hand away, stumbling backward as if he had been burned. He cradled his aching wrist to his chest, his breath coming in ragged, shallow gasps. He stared at Izuku, truly seeing him for the first time.

 

This wasn't a weakling. This wasn't someone he could push around or bully. This was a fortress. An impenetrable, living diamond.

 

For the first time in Katsuki Bakugo’s short life, he felt a shadow cast over him. The undeniable, terrifying realization that he was not the undisputed strongest person in the room.

 

Izuku reached up and dusted a bit of ash off his shoulder, a casual, dismissive gesture that drove a spike of infuriating rivalry straight through Katsuki’s heart.

 

"We can both be amazing heroes, Kacchan," Izuku said, a genuine, warm smile finally breaking across his crystalline face. "Your explosions are super strong. But I'm going to be the shield that protects everyone. We can be the best together."

 

Katsuki grit his teeth, a furious blush of embarrassment and rage painting his cheeks. He turned away, kicking a stray block across the floor. "Shut up, Deku! I don't need to team up with a stupid walking rock! I'm going to be Number One on my own! Just you wait! One day, I'll figure out how to blow you to pieces!"

 

Izuku just chuckled, a deep, resonant sound. "I'll be waiting, Kacchan."

 

Miss Aya collapsed into a nearby chair, clutching her chest as her heart rate finally began to slow down. She looked at the blonde boy with the explosive temper, and the green, crystalline boy with the unbreakable defense.

 

She didn't know much about the future, but she knew one thing for certain. The dynamic of this generation had just been set in stone. Or rather, in diamond.

 

The Twin Stars of Musutafu had been born.

 

An unstoppable force, and an immovable object. And the world of Pro Heroes was never going to be the same once they arrived.

 

 

 

Later that evening, after a scolding from the principal, a lengthy apology from Inko to the school regarding the burned shirt, and a very tense silence between Katsuki and his mother, Mitsuki, Izuku sat on the roof of his apartment building.

 

The city stretched out before him, a sea of glittering lights and towering skyscrapers. Somewhere out there, Pro Heroes were leaping across rooftops, fighting villains, and saving lives.

 

Izuku looked down at his hands. He focused his mind, imagining the shift, the restructuring of his biology.

 

Shhh-clack!

 

His left hand elongated, forming into a massive, jagged crystalline mace. He admired the sharp edges, the way the city lights reflected off the faceted surface. He imagined himself standing in front of All Might, deflecting a villain's attack, holding the line when no one else could.

 

He didn't have to be a victim anymore. He didn't have to be the boy who needed saving.

 

He clenched his mace, a fierce, burning determination settling deep within his silicon core. He was going to train. He was going to learn everything about this body, every limit, every capability. He would learn to shoot shards, to build walls, to mold himself into the ultimate weapon of justice.

 

He was Izuku Midoriya.

 

He was unbreakable.

 

And his journey to become the greatest hero in the world had just begun.

 

 

Ten years.

 

A decade is a long time for anyone, but for a child growing up in a superhuman society, it is the crucible in which their entire future is forged. In the ten years since Izuku Midoriya’s Quirk manifested on that dusty playground, the world around him had shifted entirely to accommodate the boy made of diamond.

 

Aldera Junior High was an ordinary public school in Musutafu, but it boasted a reputation that extended far beyond its district borders. This was entirely due to the presence of two students, a pair of third-year boys known among the faculty and student body as the "Twin Stars of Aldera."

 

Sunlight streamed through the large windows of Classroom 3-A, illuminating the dust motes dancing in the warm spring air. The teacher, a balding man with a perpetually exhausted expression, stood at the podium, a thick stack of career aptitude forms in his hand.

 

"So," the teacher began, his voice carrying over the low hum of student chatter. "As third-year students, it's time to start thinking seriously about your futures and what you want to do with your lives. I could pass out these career aptitude tests..."

 

He paused, a wry smile touching his lips. He dramatically tossed the stack of papers over his shoulder, letting them flutter to the floor. "...but why bother? I know you all want to go to the Hero Course!"

 

The classroom erupted. Students leapt from their seats, cheering and showing off their Quirks. A girl enlarged her hands; a boy stretched his neck to the ceiling; another manifested a small raincloud over his desk.

 

"Yes, yes, you all have wonderful Quirks," the teacher sighed, trying to restore order. "But remember, using your Quirks in school is strictly against the rules! Settle down!"

 

"Hey, teach!" a loud, arrogant voice cut through the noise, instantly silencing the room. "Don't lump me in with this bunch of losers. I'm not sitting at the bottom of the barrel with the rest of these rejects."

 

Katsuki Bakugo sat with his feet propped up on his desk, leaning back in his chair with a smug, predatory grin. At fourteen, Katsuki had grown into a lean, muscular teenager with sharp features and a perpetually aggressive aura.

 

The class immediately turned on him, shouting indignities.

"That was uncalled for, Katsuki!"

"Who are you calling a reject?!"

 

"Bring it on, extras!" Katsuki taunted, small explosions popping like firecrackers from his palms. "My Quirk is in a completely different league than yours. I aced all the mock tests, and I'm the only one here who has a real shot at getting into U.A. High School. I'm gonna surpass All Might and become the top hero, and my name will be carved into the registry of the highest earners in the world!"

 

"Ah, yes," the teacher noted, adjusting his glasses. "Bakugo, you are going for U.A. High, aren't you?"

 

The students muttered among themselves, a mix of awe and annoyance. U.A. High was the national standard for heroics, boasting an abysmal 0.2% acceptance rate.

 

"But," the teacher continued, glancing at the back of the room. "Midoriya is also applying for U.A., isn't he?"

 

The entire class turned in unison, looking toward the far corner near the window.

 

Sitting there—or rather, occupying the space—was Izuku Midoriya.

 

At fourteen, Izuku was a physical marvel. He was exceptionally tall, standing well over six feet, with a broad, imposing frame that looked as though it had been chiseled directly from a mountain. His body was entirely composed of that same pale-green, luminescent crystal that had manifested a decade ago. Over the years, the facets of his body had sharpened and refined, giving him the sleek, formidable appearance of an armored knight. Two large, jagged crystal spikes protruded from his shoulder blades, resting flush against the specially tailored, oversized black uniform he wore.

 

Despite his intimidating, monstrous appearance, Izuku was currently hunched over his notebook, furiously muttering to himself, his massive crystalline hand delicately holding a specially reinforced titanium pencil.

 

"...Mt. Lady's debut was spectacular, but she lacks environmental awareness. If she had utilized her gigantification near the train station, she could have caused massive infrastructure damage. Still, her charm and media presence will guarantee a swift rise in the rankings..."

 

"Uh, Midoriya?" the teacher called out.

 

Izuku blinked, looking up. His large, expressive emerald eyes were the only organic-looking thing about him, contrasting sharply with his geometric face. "Oh! Um, yes, sir. I'm aiming for U.A. as well."

 

Unlike Katsuki’s declaration, which was met with annoyance, Izuku’s confirmation was met with immediate, enthusiastic support.

 

"Whoa, the Twin Stars are both going!"

"Midoriya’s definitely gonna get in. Have you seen him? He's basically a walking tank!"

"I bet he could take down the U.A. robots with his bare hands!"

 

Katsuki’s eye twitched. He slammed his feet down and whipped around to glare at the gentle giant in the back row. "Hey! Deku!"

 

Izuku didn't flinch. He looked calmly at his childhood friend. "Yes, Kacchan?"

 

"Don't think just because these extras are hyping you up that you're anywhere near my level!" Katsuki growled, pointing an explosive finger at him. "Your defense is annoying, sure, but a hero needs offensive power! I'm going to blow those entrance exam robots to ash, and I'm going to score higher than you. Got it?!"

 

Izuku smiled, a deep, resonant, musical sound vibrating from his chest. Over the years, their dynamic had settled into a fierce, hyper-competitive rivalry. Katsuki was the explosive vanguard; Izuku was the unbreakable bastion. They drove each other forward. Katsuki trained his explosions to burn hotter and strike harder, desperately trying to find a way to crack Izuku’s crystal. Izuku, in turn, trained his intellect and his Quirk versatility to ensure Katsuki never succeeded.

 

"I'll do my best, Kacchan," Izuku replied evenly, tapping his titanium pencil against his crystal chin, producing a sharp clink. "But I've been practicing my crystal generation. I think my offensive capabilities are improving."

 

"Tch. We'll see about that, rock-head," Katsuki scoffed, turning back to the front, though a competitive smirk played on his lips.

 

This was the peace Izuku knew. A world where he was respected, where his dream of becoming a hero wasn't a delusional fantasy, but an inevitable reality. Yet, beneath his calm exterior, Izuku harbored a deep-seated anxiety. He was indestructible, yes, but he lacked finesse. He was heavy, cumbersome, and relied entirely on his natural durability to win brawls.

 

If he wanted to be like All Might—a symbol who saved people with a smile—he needed to be more than just a shield.

 

 

 

The final bell rang, signaling the end of the day. Izuku packed his notebooks into his oversized backpack, carefully slinging it over his jagged shoulder spikes. His movements were deliberate. He had long ago learned to moderate his strength; a careless bump in the hallway could send a fellow student to the infirmary or shatter a doorway.

 

He walked out of the school gates, his heavy footsteps—thud, clink, thud, clink—acting as a metronome. He was engrossed in his notebook, Hero Analysis for the Future No. 13, reviewing the morning's villain fight.

 

His route home took him under a wide, concrete overpass. It was a dark, cool shortcut, devoid of foot traffic this time of day.

 

Clank.

 

Izuku paused. The sound of a manhole cover shifting echoed in the tunnel. He turned his heavy head, his emerald eyes scanning the shadows.

 

From the sewer grate, a foul-smelling, viscous, dark-green sludge began to bubble up. It rose rapidly, coalescing into a massive, formless tower of muck. Two large, manic eyes and a jagged set of teeth materialized within the fluid.

 

"A medium-sized meat shield..." the Sludge Villain hissed, its voice wet and gurgling. "Not ideal, but you'll do to hide me from him. Don't worry, kid. I'm just gonna hijack your body for a bit. It'll only hurt for a minute!"

 

Before Izuku could react, the Sludge Villain lunged, exploding outward like a tidal wave of mud, completely engulfing Izuku’s crystalline body.

 

The villain attempted to force his liquid form into Izuku's mouth and nose to suffocate him and take control of his nervous system. But immediately, the villain realized something was horribly wrong.

 

What the hell is this?! the villain panicked internally. He’s as hard as a diamond! And where are his pores? I can't find a way in!

 

Inside the sludge, Izuku stood perfectly still. The darkness was disorienting, and the smell was atrocious—like raw sewage and rotting garbage. However, the anticipated panic of suffocation never came. Izuku’s Petrosapien biology didn't require a constant intake of oxygen. He could hold his breath for hours without feeling the slightest bit of fatigue. Furthermore, his lips were sealed tight, creating an impenetrable barrier.

 

Izuku opened his eyes within the murky sludge. He was mildly inconvenienced.

 

Okay, an ambush, Izuku thought calmly, his analytical mind kicking into high gear. Fluid-type villain. Blunt force attacks won't work; my fists would just pass through his liquid body. I need to disperse his mass or force him to retreat.

 

"Why won't you let me in?!" the Sludge Villain screamed, thrashing wildly. "Open your mouth, you damn rock!"

 

Izuku closed his eyes, focusing his energy on the surface area of his entire body. He visualized his crystalline structure shifting, multiplying, and expanding outward in all directions.

 

Shhh-clack-clack-clack!

 

With a deafening sound of grinding stone, dozens of razor-sharp, pale-green crystal spikes violently erupted from every square inch of Izuku’s body. He became a living, jagged urchin of indestructible diamond.

 

The spikes impaled the Sludge Villain's fluid form, instantly rupturing its surface tension and shredding its viscous mass from the inside out.

 

"AARGH! What the—?!" The villain shrieked in pain, forcibly peeling himself off Izuku’s body, unable to maintain his grip on the thousands of razor-sharp edges. The sludge splattered against the concrete walls of the tunnel, gasping and reforming slightly, looking at Izuku with terror.

 

Izuku retracted the spikes, his body smoothing out back to its normal, faceted state. He dropped his backpack and lowered his stance, morphing his right arm into a massive, double-edged sword.

 

"Stand down," Izuku commanded, his resonant voice echoing off the concrete. "Your Quirk is ineffective against me, and I will detain you if you attempt to attack again."

 

Before the villain could make a move, a loud, metallic CLANG echoed from the tunnel entrance. A manhole cover flew into the air, spinning like a coin, before clattering against the wall.

 

"Fear not, young man!" a booming, larger-than-life voice echoed through the underpass.

 

Izuku gasped, his emerald eyes widening. He recognized that voice. He had listened to it on loop since he was four years old.

 

From the shadows, a towering, impossibly muscular figure stepped forward. His golden hair stood up in two distinct V-shaped tufts, and a smile so bright it seemed to generate its own light was plastered across his shadowed face.

 

"For I am here!" All Might declared.

 

The Sludge Villain recoiled. "All Might?!" he shrieked, preparing to whip a tendril of muck at the Number One Hero.

 

"TEXAS SMASH!"

 

All Might didn't hesitate. He pulled back his massive fist and threw a punch that didn't even connect with the villain. The sheer wind pressure generated by the strike was like a localized hurricane. The shockwave hit the Sludge Villain, scattering his liquid body into a thousand tiny, harmless droplets against the tunnel walls.

 

The wind pressure was so intense that Izuku had to brace his heavy legs, his crystal feet digging small gouges into the asphalt to keep from being blown backward.

 

As the wind died down, All Might stood tall, holding two large plastic soda bottles. With blinding speed, he darted around the tunnel, scooping up the scattered remnants of the villain and securing the caps.

 

Izuku was frozen. His sword arm retracted, folding back into a normal hand. It was him. It was really him.

 

All Might turned, tapping the bottles in his cargo pants pocket. "Excellent work holding him off, young man! Though it seems your Quirk is quite formidable on its own! Apologies for getting you caught up in my villain pursuit!"

 

"A-All Might..." Izuku stammered, his usually calm demeanor shattering into a thousand pieces of pure fanboy hysteria. "Oh my goodness! It's really you! I-I'm a huge fan! I have all your merchandise, and I've watched all your interviews!"

 

All Might let out a booming laugh, striking a heroic pose. "A fan, you say? Thank you, citizen! I must be off now to deliver this miscreant to the police!"

 

"Wait!" Izuku panicked, looking around frantically for something to sign. He spotted his dropped notebook. "C-Could you sign my notebook? Please?!"

 

He picked up the notebook, opening it to a blank page, only to find a massive, looping signature already taking up an entire two-page spread.

 

"HE ALREADY SIGNED IT!" Izuku bowed repeatedly, his crystal body clinking. "Thank you so much! It'll be a family heirloom! I'll pass it down to my children!"

 

"Well, it's nice to meet a fan with such sturdy enthusiasm!" All Might said, stretching his powerful legs. "But a hero's work is never done! Stay safe, young crystal man!"

 

With a powerful leap, All Might shot out of the tunnel and into the sky, disappearing over the city skyline like a human missile.

 

Izuku stood alone in the tunnel, hugging the notebook to his hard chest. His encounter with his idol had been brief, but it fueled the fire in his soul. "I'm going to U.A.," he whispered to himself. "I'll make him proud."

 

High above the city, All Might soared through the air. However, beneath his massive, smiling facade, something was wrong. A sharp, burning pain twisted in his side. A cough forced its way up his throat, and a few drops of blood speckled his chin.

 

Damn it, All Might thought, gritting his teeth. My time limit... I'm already past it.

 

As he reached for his pocket to check on his prisoner, his heart dropped into his stomach. The pocket was empty. He patted his side frantically, realizing that when he had landed his powerful leap, the jarring impact must have knocked the bottles loose.

 

Somewhere below him, falling into the bustling streets of Musutafu, was a very angry, very desperate Sludge Villain.

 

 

 

Izuku was walking through the shopping district, his mind replaying the Texas Smash over and over again. He was analyzing the body mechanics of the punch, trying to figure out if he could replicate that kind of wind pressure by altering the shape of his fists to be more aerodynamic.

 

His thoughts were abruptly interrupted by a deafening BOOM.

 

The ground shook beneath his heavy feet. Plumes of black smoke rose over the rooftops a few blocks away. The sound of shattering glass and screaming civilians reached his ears.

 

A villain attack? Izuku thought. The scent of burnt sugar and ozone drifted on the wind.

 

Izuku froze. Burnt sugar.

 

He knew that smell. He had lived with that smell for ten years.

 

Without another thought, Izuku broke into a sprint. His heavy footsteps cracked the paving stones beneath him as he pushed his heavy body to move as fast as he could. When he rounded the corner into the Tatooin Shopping District, he was met with a scene of utter chaos.

 

Fires raged across the street, consuming storefronts and overturned cars. A crowd of onlookers had gathered, kept back by a makeshift police barricade. Several Pro Heroes were on the scene: Death Arms, Kamui Woods, and the newly debuted Mt. Lady.

 

But none of them were doing anything.

 

Izuku pushed his way to the front of the crowd, his immense height giving him a clear view of the disaster. In the center of the fiery wreckage, the Sludge Villain from the tunnel had reformed, larger and more chaotic than before.

 

But that wasn't what made Izuku’s crystalline heart stop.

 

Trapped within the center of the sludge, struggling furiously and gasping for air, was Katsuki Bakugo.

 

Katsuki was firing off massive explosions, his face twisted in a mixture of rage and terror. But the explosions were doing more harm than good; they were setting the surrounding buildings on fire and providing the Sludge Villain with a smokescreen. The villain was using Katsuki’s Quirk against the heroes, keeping them at bay.

 

"It's no good!" Death Arms shouted, punching his fists together. "I can't get close! There's no grip, and the fire's too hot!"

 

"My wood will just burn up in there!" Kamui Woods grunted, shielding his face.

 

"I need a two-lane street to maneuver! I can't get in there!" Mt. Lady cried out in frustration.

 

"We just have to wait for a hero with a suitable Quirk!" a police officer yelled into his radio.

 

Izuku stood at the barricade, his emerald eyes wide. He saw the Sludge Villain. He saw Katsuki choking, tears of sheer panic beginning to well in his crimson eyes.

 

Wait? Izuku's mind raced. They're just going to wait? Kacchan doesn't have time! He needs oxygen!

 

In the back of the crowd, a gaunt, skeletal man with messy blonde hair clutched his stomach, coughing up blood. Toshinori Yagi—the true form of All Might—watched the scene with crushing guilt. He had dropped the bottle. This was his fault. And now, he was completely out of time. He could barely stand, let alone fight.

 

Pathetic, Toshinori thought bitterly, digging his nails into his palm. I am pathetic.

 

Then, something caught his eye.

 

A large, pale-green figure shoved past the police barricade and sprinted directly into the inferno.

 

"Hey, kid! Stop!" Death Arms roared, reaching out, but his hand merely slid off Izuku’s smooth, crystalline shoulder.

 

Izuku wasn't thinking. His legs had moved before his brain had given the order. The intense heat of the surrounding fires licked at his body, but to his Petrosapien physiology, it was nothing more than a warm summer breeze. The flames couldn't burn his diamond skin.

 

"You again?!" the Sludge Villain roared, recognizing the boy who had shredded him earlier. "I'll teach you to mess with me!"

 

The villain whipped a massive tendril of sludge, aimed directly at Izuku like a battering ram.

 

Izuku didn't slow down. He didn't flinch. As he ran, he slammed his heavy right foot into the asphalt, digging his crystal toes deep into the ground for leverage. He drew his right arm back, and in a flash of shifting mechanics, transformed it into a colossal, flat shield of crystal.

 

The sludge tendril slammed into the shield with the force of a truck. Izuku slid back a few inches, the asphalt tearing beneath his feet, but he held his ground. He was the immovable object.

 

"Deku?!" Katsuki gasped from within the sludge, his eyes wide in disbelief.

 

"Hang on, Kacchan!" Izuku yelled.

 

Izuku knew he couldn't punch the liquid, and spiking his body wouldn't work to pull Katsuki out without potentially hurting him. He needed to incapacitate the villain's solid points. He looked at the villain's massive, bulging eyes.

 

Piercing damage. Pin him down!

 

Izuku dropped his shield arm. He raised his left hand, pointing it directly at the Sludge Villain. The crystal on his forearm shifted, forming several hollow, tube-like structures.

 

Sh-sh-sh-shoot!

 

With a sound like a pneumatic nail gun, Izuku fired a rapid volley of diamond-hard crystal shards from his arm. The projectiles sliced through the air and embedded themselves directly into the Sludge Villain's massive eyeballs and the surrounding concrete walls, pinning the liquid beast to the alleyway behind him.

 

"GAAAAAAH!" the Sludge Villain shrieked in absolute agony, his grip slackening drastically as his concentration shattered.

 

"Kacchan! Now!" Izuku roared.

 

Sensing the loosened grip, Katsuki unleashed a massive, two-handed explosion, blowing away the remaining sludge around his face and chest. He gasped desperately for air, falling to his hands and knees on the hot pavement.

 

Izuku immediately lunged forward, grabbing Katsuki by the collar of his school uniform with his normal crystal hand, and ripped him completely out of the sludge puddle, tossing him roughly but safely behind his own massive frame.

 

The crowd erupted into cheers. The heroes were stunned into silence. A middle schooler had just outmaneuvered all of them in a matter of seconds.

 

Toshinori Yagi watched, his sunken blue eyes wide with awe. This boy... he didn't just have a powerful Quirk. He had the instincts of a true hero. He had stepped into danger without a second thought to save a life, while the professionals had stood by and made excuses.

 

A hero, Toshinori thought, feeling a spark of fire reignite in his dying embers of a body. A true hero puts his life on the line. What kind of Symbol of Peace am I if I don't do the same?!

 

The Sludge Villain, enraged and blinded, pulled the crystal shards out of his eyes, roaring in fury. He gathered every ounce of his liquid mass, towering high above the street, preparing to crush Izuku and Katsuki under a tidal wave of muck.

 

Izuku braced himself, raising both arms to form a massive crystalline dome over himself and Katsuki.

 

But the attack never came.

 

A sudden, overwhelming pressure descended upon the street. The flames flickered and died, suffocated by the sheer force of a man stepping forward.

 

Before Izuku could form his dome, a massive figure materialized between him and the Sludge Villain. Blood dripped from his mouth, and steam rolled off his rippling muscles, but his stance was unyielding.

 

"ALL MIGHT?!" Izuku and Katsuki yelled in unison.

 

"I really am pathetic," All Might said, his voice low and vibrating with immense power. He turned his head slightly, giving Izuku a bloody, ferocious smile. "I told you what makes a champion, but I didn't live up to my own ideals! Pros are always risking their lives!"

 

All Might grabbed the villain's descending tendril with one hand, anchoring himself to the earth. He pulled his right fist back, the muscles in his arm expanding to an impossible degree.

 

"DETROIT..."

 

The villain realized his doom and tried to flee, but he was trapped.

 

"...SMASH!"

 

All Might unleashed a devastating uppercut. The shockwave wasn't just a burst of wind; it was a localized tornado. The Sludge Villain was instantly obliterated, scattered into microscopic drops of rain. The sheer force of the blow traveled upward, piercing the atmosphere.

 

Izuku stood, shielding Katsuki from the gale-force winds with his massive body. When the dust settled and they looked up, the clouds above Musutafu had been parted in a massive, perfect circle.

 

It began to rain.

 

All Might stood amidst the downpour, his fist still raised to the sky, breathing heavily. The crowd was dead silent, staring in absolute reverence.

 

And then, the cheering began.

 

 

 

The aftermath was a blur of flashing lights, reprimands, and praise.

 

The Pro Heroes had swarmed Katsuki, praising him for his resilience and the power of his Quirk, offering him future internships.

 

Izuku, on the other hand, was getting a severe scolding from Kamui Woods and Death Arms.

 

"What were you thinking, kid?!" Death Arms yelled, though his tone held a grudging respect. "You could have gotten in the way! Leave the hero work to the pros!"

 

"But... you weren't doing anything," Izuku pointed out reasonably, his voice calm. "Kacchan was suffocating. I had a clear path to incapacitate the villain with projectile shards, and my body is impervious to the surrounding fire. Tactically, it was the only viable option to prevent casualties."

 

Death Arms opened his mouth to argue, then closed it, grumbling something about "smart-aleck kids with tank Quirks."

 

Eventually, the scene was cleared, and Izuku was allowed to leave. He walked down a quiet residential street, the setting sun casting long, orange shadows across his crystalline body. He was exhausted. Firing shards took a decent amount of his body's mineral reserves, and he was already craving a salt block.

 

"Hey! Deku!"

 

Izuku stopped, turning around. Katsuki was storming down the street toward him, his hands stuffed in his pockets, his face locked in a vicious scowl.

 

Katsuki stopped a few feet away, panting slightly. He glared at Izuku, his pride warring with his reality.

 

"Listen here, you stupid rock!" Katsuki yelled, pointing a finger at Izuku’s chest. "I didn't ask for your help! I had him right where I wanted him! I could have blasted my way out on my own! Don't you dare look down on me! I owe you nothing!"

 

With that, Katsuki spun on his heel and stomped away, his shoulders tense.

 

Izuku watched him go, a soft smile on his geometric face. "You're welcome, Kacchan," he whispered to the empty street.

 

"He's a fiery one, isn't he?"

 

Izuku nearly jumped out of his heavy skin. He spun around, his crystal joints clinking violently.

 

Standing out of a nearby alleyway was All Might. The Number One hero was striking a pose, completely ignoring the fact that he had appeared out of nowhere.

 

"A-All Might?!" Izuku gasped. "What are you doing here? How did you lose the reporters?"

 

"Hahaha! I stand for justice, not soundbites!" All Might laughed, flexing his biceps. "I came to find you, young man! Because I—"

 

Suddenly, All Might coughed violently. A fountain of blood erupted from his mouth, and a massive cloud of steam enveloped his body.

 

Izuku panicked, taking a step forward. "All Might?! Are you okay?!"

 

When the steam cleared, the towering Symbol of Peace was gone. In his place stood a skeletal, emaciated man in clothes that were far too large for him. He wiped blood from his chin, looking exhausted.

 

Izuku stared, his emerald eyes wide. He looked around frantically. "W-Where did All Might go? Who are you? Are you an imposter?!"

 

"I am All Might," the skeletal man sighed, his voice raspy. He lifted his shirt, revealing a horrific, jagged scar that covered the entire left side of his chest. "Five years ago, a villain did this to me. Half my respiratory system was destroyed. I can only do hero work for about three hours a day now."

 

Izuku’s encyclopedic knowledge of heroes immediately kicked in. "Five years ago? Was it Toxic Chainsaw?"

 

"You know your stuff," All Might chuckled dryly. "But no, that punk couldn't scratch me. The world doesn't know about this. They can't know. The Symbol of Peace cannot be seen as weak. I have to smile to hide the fear inside me."

 

Toshinori walked closer to Izuku, looking up at the imposing, crystalline teenager.

 

"I came here to thank you, young man. And to apologize," Toshinori said, his tone turning dead serious. "If I hadn't heard your story... if I hadn't seen your actions today... I would have been a fake hero. You taught me a lesson today."

 

Izuku was stunned. "M-Me? But I didn't do anything! I just jumped in because Kacchan looked like he was asking for help!"

 

"Exactly," Toshinori smiled softly. "Top heroes have stories about them from their school days. Most of their stories have one thing in common: their bodies moved before they had a chance to think."

 

Toshinori placed a bony hand on Izuku’s hard, cool, crystal shoulder.

 

"You have a powerful Quirk, young man. A Quirk fit for a top pro," Toshinori said, looking directly into Izuku’s eyes. "But power alone does not make a hero. It is the heart. The willingness to sacrifice oneself for another. Today, out of everyone in that crowd, the boy made of diamond was the only one with a heart of gold."

 

Toshinori stepped back, standing tall despite his frail form.

 

"You can become a great hero," Toshinori declared.

 

Tears pricked the corners of Izuku’s eyes. For ten years, he had known he had the power. He knew he was unbreakable. But to hear his idol, the greatest hero in the world, validate his spirit... it was a dream come true.

 

"Thank you," Izuku whispered, bowing his heavy head.

 

"Now then!" Toshinori clapped his hands together, his demeanor shifting back to business. "You mentioned you are aiming for U.A. High School, correct?"

 

"Yes, sir!" Izuku nodded eagerly.

 

"I watched your movements today," Toshinori analyzed. "You are incredibly durable, and you possess raw tactical intelligence. But your physical movements... they are sluggish. You rely too heavily on your Quirk's natural defenses to take hits rather than avoiding them, and your hand-to-hand combat technique is nonexistent. A villain with an armor-piercing Quirk, or one that vibrates at high frequencies, could shatter you if you just stand there and take it."

 

Izuku’s eyes widened. That was exactly what he had been worried about.

 

"If you enter U.A. relying solely on your durability, you will hit a wall," Toshinori warned. "I want to help you break past it."

 

"Help me?" Izuku asked, confused.

 

"I have ten months until the U.A. Entrance Exam," Toshinori smiled, a glint of excitement in his hollow eyes. "I am going to take you on as my personal pupil. I will teach you how to fight. I will teach you how to move that heavy body of yours. I will forge you into a warrior, not just a shield."

 

Izuku stared at the gaunt man, his mind reeling. The Number One Hero wanted to train him. It was an opportunity beyond comprehension.

 

Izuku clenched his right hand. The crystal shifted, a sharp blade sliding out of his forearm, gleaming in the twilight. He retracted it immediately, stepping forward.

 

"I won't let you down, All Might," Izuku declared, his voice resolute, ringing like struck glass. "I want to be the hero who protects everyone. Please, train me!"

 

Toshinori grinned. The boy was already a diamond. But over the next ten months, Toshinori was going to put him under pressure, cut away his flaws, and polish him until he shined brighter than any hero in history.

 

"Meet me at Dagobah Municipal Beach Park tomorrow at 6:00 AM," Toshinori instructed. "And bring your work boots. We have a lot of heavy lifting to do."

 

 

The dawn air over Dagobah Municipal Beach Park was crisp, carrying the salty tang of the ocean mixed with the faint, metallic scent of rusted iron. For years, the beach had been an illegal dumping ground, a mountain range of discarded appliances, crushed cars, and forgotten trash.

 

But over the last ten months, those mountains had steadily vanished.

 

"Again!"

 

A sharp, authoritative voice cut through the rhythmic crashing of the waves.

 

In the center of a newly cleared stretch of golden sand, Izuku Midoriya stood panting. He didn't sweat—his Petrosapien biology didn't possess sweat glands—but the exertion was evident in the faint, pulsing luminescence of his pale-green crystalline body. He was glowing with internal heat, the facets of his chest rising and falling as he cycled oxygen through his complex internal core.

 

Across from him stood Toshinori Yagi, leaning heavily on a wooden cane, wrapped in an oversized trench coat to ward off the morning chill.

 

"You're planting your feet too firmly, Young Midoriya!" Toshinori barked, his sunken blue eyes sharp and critical. "Your Quirk makes you incredibly heavy. If you root yourself to the ground, you become a stationary target! A heavy bag! You must learn to flow. Shift your weight from your hips, not your shoulders! Now, come at me!"

 

Izuku nodded, his crystal neck joints letting out a soft clink. He raised his fists, settling into the traditional boxing stance Toshinori had been drilling into him for nearly a year.

 

Because Izuku possessed an unbreakable body and superhuman strength by default, Toshinori hadn't needed to put him through the grueling physical conditioning required to inherit a stockpiling Quirk. Instead, the ten months at Dagobah Beach had been a masterclass in martial arts, body mechanics, and Quirk stamina.

 

Toshinori had quickly realized that Izuku fought like a brawler who knew he couldn't be hurt. It was sloppy. It was dangerous.

 

“If you rely entirely on your armor,” Toshinori had warned him on day one, “you will eventually meet a villain with a hammer big enough to crack it. A hero avoids damage whenever possible, so they are in peak condition when taking damage is the only option.”

 

Izuku stepped forward, pushing off the sand. He didn't morph his arms into blades or maces; this was pure hand-to-hand combat. He threw a heavy, sweeping left hook.

 

Toshinori, despite his frail appearance, possessed the muscle memory and battle instincts of the Number One Hero. He gracefully ducked under the heavy crystalline fist. The wind pressure from Izuku’s punch ruffled Toshinori’s blonde hair.

 

"Too wide!" Toshinori critiqued, tapping Izuku’s exposed ribcage with his cane. "You're telegraphing!"

 

Izuku didn't pause. Using the momentum of his missed left hook, he pivoted on his right foot, twisting his heavy torso. He brought his right fist up in a tight, devastating uppercut.

 

Toshinori’s eyes widened slightly in approval. He leaned back just enough for the crystal fist to pass an inch from his nose.

 

Izuku immediately dropped his center of gravity, bringing his arms up to guard his face in a tight shell, expecting the counterattack.

 

"Good!" Toshinori called out, stepping back and leaning on his cane. "Much better. You chained the attacks flawlessly, and you remembered to guard your vulnerable sensory organs. Your reflexes have improved exponentially."

 

Izuku dropped his guard, letting out a long breath. The bright glow of his body dimmed back to its normal, cool translucent green. "Thank you, All Might. It's... it's still hard to get used to moving without overcommitting. I weigh nearly four hundred pounds now."

 

"And that weight is your greatest weapon, provided you control its trajectory," Toshinori smiled warmly, stepping forward to pat Izuku’s hard shoulder. "You've done magnificently, my boy. Look around you."

 

Izuku turned his head. The sun was finally peaking over the horizon, casting brilliant rays of gold across the water. The beach, once a wasteland of garbage, was completely pristine. The sand was spotless. Izuku had spent the first five months hauling refrigerators, pickup trucks, and steel beams by hand, using the awkward, shifting weights to learn how his center of gravity worked. The last five months had been pure combat and tactical Quirk application.

 

"You didn't just clean a beach, Young Midoriya," Toshinori said softly, staring out at the ocean. "You restored a piece of this community. You put in the grueling, unglamorous work that most modern heroes ignore in favor of flashy fights on camera. You have the soul of a true hero."

 

Izuku felt a familiar tightness in his throat. Even after ten months of training alongside his idol, the praise never failed to overwhelm him. "I... I couldn't have done it without you, All Might. You showed me how to use my body properly."

 

Toshinori turned to face him, his skeletal face breaking into a wide, genuine smile. "I only gave you the tools. You built the house. Today is the U.A. Entrance Exam. You are walking into a crucible, but I want you to remember something."

 

Toshinori pointed a bony finger at Izuku’s crystalline chest.

 

"You are unbreakable. Not just your body, but your spirit. When the pressure mounts today, do not crack. Shine."

 

Izuku straightened his posture, snapping a sharp salute, his crystal arm reflecting the morning sun. "Yes, sir!"

 

 

 

The towering gates of U.A. High School were a monument to the grandeur of hero society. The main building consisted of massive, H-shaped glass structures that gleamed imposingly against the clear blue sky. Hundreds of nervous middle schoolers swarmed the entrance, buzzing with a mixture of excitement and sheer terror.

 

Izuku stood at the edge of the campus, staring up at the gates. He was wearing his standard middle-school uniform, though it had been heavily modified. The seams were reinforced with Kevlar threading, and the sleeves were removed entirely, leaving his massive, pale-green, jagged arms exposed to the open air. His shoulder spikes jutted up aggressively behind his neck.

 

Every time he took a step, the heavy thud of his boots and the soft, musical clink-clink of his joints drew stares from the other applicants.

 

"Whoa, look at that guy..."

"Is his whole body a crystal? That's an intense mutation."

"He looks like a pro already. I wouldn't want to fight him."

 

Izuku did his best to ignore the whispers, keeping his eyes fixed on the entrance. He repeated Toshinori’s breathing exercises, centering his mind.

 

"Out of my way, Deku!"

 

Izuku didn't even need to turn around to recognize the voice. Katsuki Bakugo stormed past him, his hands shoved deep into his pockets, his crimson eyes glaring daggers at the school building. Over the last ten months, Katsuki had grown even more intense. Their rivalry had only sharpened; Katsuki had spent every waking moment trying to maximize the heat and concussive force of his explosions, desperate to find a way to shatter Izuku’s defense.

 

"Good morning, Kacchan," Izuku said politely, stepping aside. "Good luck on the exam."

 

"Don't patronize me, rock-head," Katsuki sneered, pausing to look over his shoulder. "I don't need luck. I'm going to annihilate this exam, and I'm going to score higher than you. Just watch your back. If you get in my way, I'll blow you to dust."

 

Izuku just smiled softly. "I'll do my best to keep up, Kacchan."

 

Katsuki clicked his tongue in annoyance and stomped ahead, parting the sea of applicants through sheer intimidation.

 

Izuku took a deep breath and began the walk up the long, paved pathway to the main doors. He was so focused on visualizing the written exam that he didn't notice the uneven paving stone jutting out of the path.

 

His heavy steel-toed boot caught the edge.

 

For a normal teenager, tripping is a minor embarrassment. For a four-hundred-pound teenager made of solid crystal, tripping is a catastrophic event that usually ends with a crater in the concrete.

 

Izuku tipped forward, his eyes widening in panic. Oh no! I'm going to smash the pavement! I might hit someone!

 

He braced himself for the earth-shattering impact, but it never came.

 

A few inches from the ground, his body abruptly halted. He was floating.

 

"Phew! Caught you!" a cheerful, bubbly voice chimed from beside him.

 

Izuku slowly tilted his head. Standing next to him was a girl with round cheeks, warm brown eyes, and short auburn hair. She was holding her hands together, her fingertips glowing with a soft pink light. She looked slightly strained, a drop of sweat rolling down her temple.

 

"Wow, you are super heavy!" the girl giggled, pressing her hands together tighter. "I almost couldn't catch you in time! Are you okay?"

 

Izuku scrambled to right himself, floating awkwardly in the air until the girl pressed her fingertips together and called out, "Release!"

 

Izuku dropped the remaining few inches, his boots hitting the pavement with a heavy, resonant THUD that shook the ground slightly.

 

"I-I'm so sorry!" Izuku stammered, bowing repeatedly, his joints clicking rapidly. "Thank you for saving me! I wasn't paying attention, and I could have caused a massive scene, and your Quirk is amazing, nullifying gravity like that—!"

 

"It's no problem!" the girl smiled brightly, waving her hands. Then, she stopped and really looked at him. Her eyes widened, reflecting the pale green of his crystalline body.

 

Izuku froze. He was used to people staring at him. He was used to fear, intimidation, or clinical curiosity. He braced himself for the usual comments about how scary or monstrous he looked.

 

"Oh my gosh," the girl breathed, stepping closer. "You are... so pretty!"

 

Izuku’s brain short-circuited.

 

"...Huh?"

 

"Your Quirk!" she beamed, pointing at his arm. "It's like looking at a giant emerald! The way the sunlight catches the edges... it's really beautiful! It must be super strong, too!"

 

Izuku felt an entirely new sensation. Beneath his crystal skin, a wave of heat rushed to his face. Since he couldn't blush, his Petrosapien biology reacted to the intense embarrassment by causing the crystal around his cheeks and neck to glow a bright, luminescent mint-green. He let out a high-pitched, musical chime of surprise.

 

"B-Beautiful?!" Izuku squeaked, waving his hands frantically. "N-No one has ever called me that! Intimidating, maybe, or rock-head, but never... thank you! Your Quirk is incredible too! It's highly versatile for rescue operations and—!"

 

"I'm Ochaco Uraraka!" she said, cutting off his muttered rant with a laugh. "It's nice to meet you... um..."

 

"Izuku! Izuku Midoriya!"

 

"Well, Midoriya, let's both do our best today!" Uraraka pumped her fist in the air. "See you inside!"

 

As she jogged away, Izuku stood frozen on the pathway, his face still glowing bright green like a neon sign. I just talked to a girl. And she said I was beautiful.

 

"Excuse me."

 

A stern, booming voice broke him out of his reverie. Izuku turned to see a tall, broad-shouldered boy with slicked-back dark blue hair and rectangular glasses. He moved with rigid, robotic precision.

 

"While camaraderie is admirable," the bespectacled boy said, adjusting his glasses, "you are blocking the central walkway. Your physical mass is considerable, and lingering here disrupts the flow of traffic. Please proceed into the auditorium immediately!"

 

"Oh! Right, sorry!" Izuku bowed, quickly hurrying inside.

 

 

 

The written portion of the exam was, surprisingly, the easiest part for Izuku. His ten months of training hadn't just been physical; he had devoured textbooks on hero law, physics, and mathematics. He finished the test with thirty minutes to spare, double-checking his answers before waiting patiently.

 

Once the written exams were collected, the applicants were ushered into a massive, stadium-seating auditorium. The lights dimmed, and a solitary spotlight snapped onto the stage.

 

"EVERYBODY SAY HEY!!!"

 

The Voice Hero, Present Mic, leaned backward, screaming into the microphone around his neck.

 

The auditorium was dead silent.

 

Present Mic didn't miss a beat. "Tough crowd! That's fine, examinees! Let me give you the lowdown on how today's practical exam is gonna rock your world!"

 

Behind him, a massive screen flickered on, displaying a map of several mock cities.

 

"You'll be conducting a ten-minute urban battle simulation! You can bring whatever you want with you! After this presentation, you'll head to your assigned Battle Centers! Okay?!"

 

Izuku looked down at his examination ticket. "I'm in Battle Center B."

 

Katsuki, sitting in the seat next to him, glanced over. "I'm in Center A. They split us up so we can't work together."

 

"Or so you don't blow me up," Izuku whispered with a smirk.

 

"Shut up, rock-head."

 

Present Mic continued, explaining the point system. There were three types of robotic villains: One-Pointers, Two-Pointers, and Three-Pointers. The goal was to destroy them and rack up points.

 

"Excuse me! I have a question!"

 

A silhouette stood up in the middle of the dark auditorium. It was the bespectacled boy from the entrance. A spotlight hit him as he pointed rigidly at the pamphlet in his hand.

 

"On the printout, there are four types of villains! If this is a misprint, U.A., the top hero academy in Japan, should be ashamed of this foolish mistake! We are here because we wish to be molded into exemplary heroes!"

 

The boy then whipped around, pointing directly at Izuku and Katsuki’s row.

 

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

 

Izuku immediately clamped his hands over his mouth, his face glowing bright green again in embarrassment. "S-Sorry..."

 

Katsuki, however, wasn't about to take that. He leaned forward, sparks popping off his palms. "Hey, Four-Eyes! You got a problem?! Why don't you come up here and say that to my face?!"

 

"Please, Kacchan, don't cause a scene," Izuku whispered frantically, trying to pull his volatile friend back into his seat.

 

Present Mic waved his hands, trying to restore order. "Okay, okay, Examinee Number 7111! Thanks for the great message! The fourth villain type is worth zero points! It's an arena trap! Have you ever played Super Mario Brothers?! It's like a Thwomp! There's one in every center! You can beat it, but there's no point! I recommend you run away from it!"

 

The bespectacled boy bowed deeply. "Thank you very much! Please excuse my interruption!" He sat back down.

 

Izuku processed the information. A zero-pointer. An obstacle meant to test spatial awareness and threat assessment. If there's no reward for fighting it, the most logical choice is evasion.

 

"That's all from me!" Present Mic shouted, striking a dramatic pose. "I'll leave you with our school motto! As the great hero Napoleon Bonaparte once said... a true hero is one who overcomes life's misfortunes! Go beyond... PLUS ULTRA!!"

 

 

 

Battle Center B was not a mere set; it was a sprawling, fully realized metropolis. Skyscrapers towered over paved streets, complete with alleyways, streetlights, and parked cars.

 

Dozens of applicants stood behind the massive steel gates, stretching and psyching themselves up. Izuku stood near the back, closing his eyes and listening to his own internal rhythm. He could hear his heavy heartbeat, the slow grind of crystal against crystal as he rolled his shoulders.

 

He saw Uraraka standing near the front, looking pale and nervous. He wanted to go over and wish her luck, to repay her for earlier, but before he could take a step, a hand chopped down onto his shoulder.

 

It was the bespectacled boy, Iida.

 

"That girl appears to be trying to focus," Iida said sternly. "Are you going to distract her with your muttering again? What is your intent here?"

 

Izuku looked down at the boy. Izuku was significantly taller, his crystalline form casting a shadow over Iida. He didn't get angry, but his emerald eyes narrowed slightly in focus.

 

"My intent is to pass this exam," Izuku said, his voice calm, resonant, and entirely devoid of hesitation. "I would suggest you focus on yourself."

 

Before Iida could respond, Present Mic’s voice echoed from a massive speaker tower.

 

"RIGHT, LET'S START!!"

 

The applicants jumped. The gates hadn't even fully opened, but they were already unlocked.

 

"WHAT'S WRONG?! THERE ARE NO COUNTDOWNS IN A REAL BATTLE! RUN, RUN, RUN, EXAMINEES! YOU'RE WASTING TIME!!"

 

The crowd surged forward, a stampede of Quirks and adrenaline. Izuku didn't run with them. Running normally with his weight was inefficient and loud.

 

Instead, Izuku dropped to a low crouch, touching his hands to the pavement. He remembered watching the Pro Hero Frozone on television, and the Pro Hero Edgeshot's swift, gliding movements.

 

Petrosapien slide!

 

Izuku unleashed a stream of smooth, frictionless crystal from his boots and palms directly onto the asphalt. He pushed off, skating forward at incredible speed. He bypassed the running crowd in seconds, a pale-green blur sliding over a shimmering track of generated diamond.

 

"Whoa! What the heck?!" an applicant yelled as Izuku blew past them.

 

Izuku entered the main avenue of the mock city. Instantly, three One-Pointer robots rolled out of an alleyway, their red optical sensors locking onto him.

 

“Target acquired. Commencing hostilities!” the robots droned in unison.

 

Izuku didn't slow his slide. He raised his right arm, focusing his mind. Shhh-clack! His arm instantly elongated, transforming into a massive, heavy crystal war hammer.

 

He vaulted off his crystal track, launching his heavy body into the air. He didn't just swing the hammer; he used his entire body weight, just as All Might had taught him, twisting his hips to generate maximum torque.

 

The hammer slammed into the center robot's chassis. The impact was devastating. The robot didn't just break; it crumpled like a tin can hit by a sledgehammer, sparks and oil exploding outward.

 

Using the momentum of the swing, Izuku landed on his feet, instantly morphing his left arm into a razor-sharp blade. He spun, slicing cleanly through the neck joints of the remaining two One-Pointers. The robotic heads hit the ground with a synchronized clang.

 

"Three points," Izuku muttered, his breath steady.

 

He didn't stop. He broke into a sprint, his boots cracking the pavement.

 

A Two-Pointer, possessing a scorpion-like tail, lunged at him from a rooftop.

 

Izuku didn't dodge. He raised his left arm, forming a thick crystal shield. The metal stinger struck the diamond shield with a deafening screech, failing to even leave a scratch on Izuku's surface.

 

With his right hand, still normal, Izuku grabbed the stinger, anchoring himself to the ground. He yanked downward with all his superhuman might. The robot was ripped from the rooftop, crashing into the street below. Izuku stomped his heavy, spiked boot directly through its main processing unit.

 

"Five points."

 

For the next seven minutes, Izuku was a force of nature. He moved with a brutal, terrifying efficiency. He didn't show off; he didn't waste movements. When a cluster of Three-Pointers opened fire on him with rubber bullets and low-yield lasers, Izuku didn't bother dodging. He simply charged straight through the barrage. The projectiles bounced off his faceted chest like rain off a windshield, the lasers refracting harmlessly against his pale-green skin.

 

He fired volleys of diamond shards to pin distant robots to walls, then skated in to finish them off with precise, devastating blows.

 

In the observation room hidden high above the arena, the faculty of U.A. High watched the monitors in awe.

 

"Incredible," murmured Midnight, the R-Rated Hero. "He’s a juggernaut. He’s taking zero evasive maneuvers against projectile fire because he simply doesn't need to."

 

"It's not just his durability," noted Snipe, adjusting his mask. "Look at his strikes. He's heavy, but he's not relying on brute force alone. He's targeting joints, sensors, and structural weak points. He's been trained by a pro."

 

"His Quirk classification is Petrosapien, a full-body silicon mutation," Principal Nezu squeaked, sipping a cup of tea. "He can alter his appendages into weapons, generate structures, and regenerate damage. A truly terrifying combination of offense and defense."

 

In the back of the dark room, in his skeletal form, Toshinori Yagi watched Izuku’s monitor with immense pride. You're doing it, my boy. You're showing them exactly who you are.

 

"He has forty-five villain points," a tired, gruff voice spoke up from the corner. Eraserhead stared intently at Izuku’s screen. "But it's easy to look good when there's no real danger. Let's see how he handles true adversity."

 

Eraserhead reached forward and pressed a large, red button on the console.

 

 

 

Down in Battle Center B, Izuku had just smashed his fifty-second point when the ground began to tremble.

 

It wasn't a small tremor. It felt like a massive earthquake. The applicants around him stopped, looking around in panic.

 

"What's happening?!"

"Is it an earthquake?"

 

BOOM.

 

The sound of an explosion echoed from the center of the city. A massive shadow fell over the street.

 

Izuku looked up, and his emerald eyes widened.

 

Rising above the six-story buildings was the Zero-Pointer. It was a colossal, tread-driven behemoth, easily the size of a skyscraper. It possessed massive, piston-driven arms and a glowing red optical visor that swept the area like a searchlight.

 

With a mechanical roar, it swung one of its arms, completely obliterating the top half of a nearby building. Debris rained down on the streets below.

 

"IT'S A MONSTER!"

"RUN AWAY! IT'S THE ZERO POINTER!"

 

The applicants broke into a dead sprint, fleeing the avenue as the behemoth rolled forward, crushing parked cars and streetlights beneath its massive treads.

 

Izuku stood his ground, analyzing the threat. Present Mic was right. There's no strategic value in fighting that. The armor plating is too thick for my blades, and the sheer kinetic force of a blow from that arm could probably shatter even my crystal.

 

He turned to run, following the crowd. But as he pivoted, a faint, desperate cry reached his ears over the sound of crumbling concrete.

 

"Ow... my leg..."

 

Izuku stopped dead. He whipped his head around.

 

Near the base of the approaching Zero-Pointer, trapped under a massive slab of rubble from the destroyed building, was Uraraka. She was pinned by her ankle, struggling frantically to push the concrete off, but she was exhausted.

 

The robot's massive treads were rolling relentlessly forward. It was going to crush her in less than thirty seconds.

 

Izuku looked at the fleeing applicants. No one else had noticed her. No one was stopping.

 

The mind of a hero... All Might's words echoed in his head. ...moves before they have a chance to think.

 

Izuku didn't run away. He turned back, his heavy boots slamming into the pavement as he sprinted directly toward the colossal machine.

 

"Hey! What are you doing?!" yelled Iida, who was running past him. "Are you insane?!"

 

Izuku ignored him. He kept his eyes locked on Uraraka and the towering tread of the Zero-Pointer.

 

His analytical mind processed the situation at lightspeed.

 

Option A: Smash the robot's leg.

Result: The structural integrity fails, and hundreds of tons of metal collapse directly onto Uraraka. Unacceptable.

 

Option B: Catch the tread and hold it back.

Result: The kinetic force of the machine will drive my body straight into the pavement like a nail. I'll be buried, and she'll be crushed. Unacceptable.

 

He needed to stop the machine. He needed to halt its momentum entirely, freezing it in place without causing it to topple over.

 

Izuku reached Uraraka, standing directly between her and the looming wall of metal treads. The machine was only twenty feet away, casting a terrifying shadow over them.

 

"M-Midoriya?!" Uraraka cried, tears streaming down her face. "Run! It's too big!"

 

Izuku didn't look back at her. He dropped to his knees, ignoring the sharp pain of his crystal digging into the asphalt. He placed both of his massive, pale-green hands flat against the ground.

 

He closed his eyes. He reached deep into the core of his being, tapping into the very absolute limit of his Petrosapien biology. He didn't just want to create a weapon. He wanted to alter the environment. He pushed his Quirk through his arms, directly into the earth beneath the street.

 

The green glow emanating from his body intensified, blindingly bright.

 

"I won't let you get hurt," Izuku whispered, his voice vibrating with immense power.

 

SHHH-KRRAAAKKK!

 

The sound was apocalyptic. The street didn't just crack; it exploded upward.

 

From the asphalt, a titanic, jagged glacier of solid pale-green crystal erupted into existence. It shot forward like a tidal wave of diamond, expanding exponentially in milliseconds.

 

The crystal glacier slammed into the undercarriage of the Zero-Pointer with the force of a tectonic shift. It didn't push the robot; it impaled it. Massive, razor-sharp spires of indestructible diamond pierced through the metal treads, tearing into the internal gears, locking the axles, and bursting through the armored chassis.

 

The sheer density and mass of the generated crystal acted as a perfect, unbreakable wedge.

 

With an earsplitting groan of bending metal and grinding gears, the colossal machine was halted dead in its tracks. The treads squealed against the crystal, sparks showering the street, before the internal engines overloaded and died.

 

The Zero-Pointer was frozen in place, hoisted slightly off the ground by a mountain of pale-green diamond that sparkled brilliantly in the sunlight.

 

Silence fell over Battle Center B.

 

The fleeing applicants stopped, turning around. Their jaws dropped in sheer, unadulterated shock.

 

The massive robot, the unstoppable force, had been entirely neutralized by a single applicant.

 

Izuku remained on his knees, his hands still pressed to the ground, panting heavily. The glow of his body faded rapidly, and a dull ache settled into his chest. Creating that much mass in a single instant had drained his mineral reserves almost completely.

 

He slowly pulled his hands from the ground, the crystal severing its connection to the glacier. He turned around to look at Uraraka.

 

She was staring up at the towering spires of green crystal, her mouth hanging open.

 

"Are you okay?" Izuku asked gently, his resonant voice cutting through her shock.

 

He stepped over to the slab of concrete pinning her leg. He gripped it with both hands and lifted it as easily as one might lift a cardboard box, tossing it aside.

 

"I... I..." Uraraka stammered, looking from the frozen mechanical titan back to the boy made of diamond.

 

"TIME'S UP!!" Present Mic’s voice blared over the speakers.

 

A loud siren wailed, signaling the end of the exam.

 

Izuku let out a long breath, his shoulders slumping. He had done it. He had survived. He offered a large, cool crystal hand to Uraraka, helping her to her feet.

 

"Come on," Izuku smiled warmly. "Let's get you to the nurse."

 

 

 

In the observation room, the silence was absolute.

 

Eraserhead leaned back in his chair, a rare, terrifying grin spreading across his face.

 

"He didn't just survive the adversity," Eraserhead noted, his eyes locked on the screen showing Izuku helping the girl walk. "He conquered it. He used his Quirk creatively to neutralize a massive threat without causing collateral damage to the hostage."

 

"That much crystal generation..." Nezu hummed thoughtfully. "His internal energy reserves must be staggering. He essentially built a skyscraper in three seconds."

 

Toshinori Yagi gripped the railing, his heart swelling with pride. Izuku hadn't just used his durability. He had used his mind, and above all, his heart.

 

 

 

A week later, Izuku sat at the dinner table in the Midoriya apartment. Inko was nervously pacing the kitchen, wringing her hands, while Izuku stared intensely at the plain white envelope sitting on the table, stamped with the red U.A. wax seal.

 

He had spent the last week agonizing over the exam. Fifty-two points was a solid score, but was it enough? Had he lost points for failing to destroy the Zero-Pointer completely?

 

"Izuku, honey, you should open it," Inko urged, biting her lip.

 

Izuku nodded. He picked up the envelope, carefully using his sharp crystal thumbnail to slice the paper open without damaging the contents. A small, metal disc fell out, clattering onto the table.

 

Before Izuku could inspect it, the disc whirred to life. A holographic projection sprang upward, illuminating the dining room.

 

"I AM HERE AS A PROJECTION!"

 

All Might’s booming voice filled the room, his massive form displayed in the hologram, wearing a sharp yellow suit.

 

"All Might?!" Izuku gasped.

 

"Greetings, Young Midoriya!" the hologram smiled warmly. "You must be wondering why I am the one delivering this message! The truth is, I will be joining the U.A. faculty this year!"

 

Izuku’s eyes widened. All Might, teaching at U.A. It was a dream come true.

 

"You did exceptionally well on the written exam, and you scored fifty-two villain points in the practical!" All Might continued, the screen beside him showing a leaderboard. "That alone would have been enough to pass! However..."

 

All Might’s expression turned serious.

 

"The U.A. Entrance Exam is not just graded on destruction. After all, how could a hero course reject someone who saves others and does the right thing?"

 

A video began to play. It was footage from a hidden camera, showing Uraraka trapped, and Izuku turning back to face the Zero-Pointer, creating the massive crystal glacier to save her.

 

"A hero course that rejects someone for doing the right thing is no hero course at all!" All Might declared proudly. "Enter, Rescue Points! A panel of judges assigns these points based on heroic actions!"

 

The leaderboard updated.

 

Izuku Midoriya.

Villain Points: 52.

Rescue Points: 60.

Total Score: 112 points. First Place.

 

Izuku stared at the number. First place. He had beaten Kacchan. He had beaten everyone.

 

"Young Midoriya," All Might’s voice softened, filled with genuine affection. "You have proven that true strength is not just about being unbreakable. It is about using that strength to shield others. Welcome, Izuku. This is your hero academia."

 

The hologram fizzled out, leaving the room in stunned silence.

 

Izuku sat perfectly still. The crystal on his face began to glow a soft, warm green. He looked up at his mother, who was already sobbing tears of joy.

 

He didn't just have a powerful Quirk. He had earned his place.

 

The boy made of diamond was going to U.A. High School. And the world was not ready for the unbreakable hero he was destined to become.
