What if Deku had a Symbiote quirk that's overpowered

 

The smell of antiseptic and sterilized steel was the first thing Izuku Midoriya would remember about the day his life diverged from the rest of humanity.

 

He was four years old, sitting on a crinkling paper-lined exam table in a brightly lit pediatrician's office. His mother, Inko, stood beside him, her hands clasped so tightly her knuckles were white. Izuku swung his short legs back and forth, clutching an All Might action figure in his hands, oblivious to his mother’s underlying anxiety. He was just excited. Today was the day they were going to find out what his Quirk was.

 

"Now, Mrs. Midoriya, there's no need to look so worried," the doctor, a balding man with thick goggles, said with a dismissive wave of his hand. He wheeled his stool closer to the exam table, holding a small, sterilized needle. "Given that both you and your husband possess Quirks, it is highly irregular for a child to remain Quirkless by age four. Sometimes, the body just needs a little... prompt. A simple blood test will tell us everything about his genetic markers."

 

"I know, Doctor," Inko said, her voice trembling slightly. "He’s just... he’s been having these nightmares lately. Saying that the shadows are talking to him. I thought perhaps it was a psychological Quirk?"

 

The doctor chuckled, a dry, raspy sound. "Children have active imaginations. Let us look at the science first. Izuku, my boy, hold out your arm. Just a small pinch."

 

Izuku, wanting to be brave like All Might, extended his chubby arm. He didn't flinch as the doctor swabbed the inside of his elbow with a cold alcohol wipe. He watched with wide, curious green eyes as the doctor brought the needle down.

 

The steel tip pierced his skin.

 

A drop of crimson blood beaded at the surface. And then, everything stopped.

 

The air in the room suddenly grew freezing cold, heavy with an unnatural pressure. Izuku didn't cry, but he gasped, his eyes dilating. A strange, vibrating hum filled the room, vibrating in the back of Inko’s teeth.

 

The single drop of red blood on Izuku’s arm didn't flow downward. It defied gravity, pooling upward, vibrating, before it suddenly turned pitch black.

 

"What the—" the doctor began, leaning in.

 

“M I N E.”

 

The voice didn't come from Izuku. It didn't come from anywhere in the room. It resonated directly inside the skulls of the doctor and Inko, a primal, guttural roar of thousands of overlapping whispers.

 

Before the doctor could pull his hand back, the black drop exploded.

 

A geyser of viscous, inky-black liquid erupted from Izuku’s small vein. It didn't splash like water; it moved with terrifying, muscular intent. The liquid shifted, hardened, and expanded in a fraction of a second, forming a massive, razor-sharp tendril. It whipped outward with the force of a freight train.

 

CRASH!

 

The doctor was thrown backward as the tendril batted him aside like a ragdoll. He slammed into the far wall, medical charts and glass vials shattering into a million pieces around him. The black mass didn't stop. It erupted further from Izuku's arm, spreading over the boy's shoulder, bubbling and hissing like boiling tar. It lashed out at the room—smashing the heavy steel desk in half, shattering the fluorescent lights above, and ripping the heart monitor from the wall.

 

"Izuku!" Inko screamed, diving forward despite her sheer terror, trying to reach her son.

 

The black mass sensed her movement. It whipped around, a terrifying, featureless blob of shifting liquid, forming into the vague shape of a massive head. It opened a maw that wasn't there a second ago, revealing rows of jagged, white, shark-like teeth. It hissed at Inko, a sound like tearing metal.

 

But then, Izuku—small, terrified, four-year-old Izuku—grabbed the black mass with his other, bare hand.

 

"No!" the boy cried out, tears streaming down his face. "Don't hurt Mommy!"

 

The mass froze. The jagged teeth retracted. The towering, terrifying spike of black liquid softened. Slowly, deliberately, the mass turned to look at the crying boy.

 

“...Host?” The voice echoed in Izuku's mind, softer this time, confused. “Mother? No hurt?”

 

"No hurt!" Izuku sobbed, hugging his knees to his chest.

 

The black liquid seemed to deflate. It slithered backward, retreating from the destroyed room, pulling back toward Izuku’s arm. Like water absorbing into a sponge, the pitch-black entity sank directly into Izuku’s skin, leaving no trace behind except for the single, tiny prick of the needle, which healed and vanished right before their eyes.

 

The room was in absolute ruins. The doctor was groaning on the floor, terrified and bleeding from a cut on his forehead. Inko dropped to her knees, trembling violently as she pulled Izuku into her chest, hiding him from the world.

 

Izuku clung to her, crying softly. But in the back of his mind, he felt something warm. Something that felt like a large, protective dog curling up to sleep right next to his heart.

 

“Safe,” the voice whispered in his mind, purring like a jet engine. “We are safe.”

 

 

 

Ten years later.

 

Izuku Midoriya sat at his desk in the back corner of his classroom at Aldera Junior High, staring blankly out the window. Outside, cherry blossom petals drifted lazily on the spring breeze. Inside, the classroom was a suffocating pressure cooker of whispers, sideways glances, and thinly veiled hostility.

 

"Did you see him looking at me?" a girl whispered two rows ahead, leaning toward her friend.

"Don't make eye contact. My mom says kids with Villain Quirks are just waiting to snap."

"I heard he almost killed a doctor when he was a baby."

 

Izuku kept his eyes firmly fixed on the window. He was used to it. Ten years of the same whispers, the same fear, the same isolation. He didn't blame them. If he didn't know what lived inside him, he would be terrified, too.

 

“I can hear them,” a deep, resonant voice rumbled inside Izuku’s head. It sounded like two grinding tectonic plates, dark and thrumming with restrained violence. “They are annoying. Like gnats. Let me out, Izuku. I will bite their heads off. Just a little. A warning.”

 

Izuku didn't move his lips, but he projected his thoughts inward, speaking directly to the entity that shared his bloodstream. No, Vesper. We don't bite people's heads off.

 

“Just the loud one,” Vesper bargained, a tendril of black thought weaving through Izuku's consciousness. “We need sustenance. They are made of meat. We like meat.”

 

We are having katsudon for dinner tonight. Mom is making it. You like katsudon.

 

There was a pause in his mind, followed by a sensation that felt distinctly like a mental grumble. “...Katsudon is acceptable. But if the gnats try to touch us, I will break their appendages.”

 

Izuku sighed softly, resting his chin in his hand. Over the past ten years, he and the entity—which they had mutually decided to name 'Vesper' after a villain in an old pre-Quirk comic book Izuku had found—had come to an understanding.

 

Vesper was a sentient, biological mutation. According to the handful of terrified specialists who had studied him from behind thick, reinforced glass, Izuku's Quirk was an anomaly of cellular evolution. His body produced a living, liquid-like biomass that possessed its own primitive consciousness. Vesper lived in Izuku's bloodstream, acting as a hyper-advanced immune system, muscular enhancer, and, when provoked, a weapon of mass destruction.

 

Izuku couldn't get sick. If he broke a bone, Vesper's biomass forcefully snapped it back into place and healed the micro-fractures in seconds. If Izuku was physically threatened, Vesper could emerge from his pores, forming an impenetrable armor of black liquid, razor-sharp tendrils, or raw, hulking muscle mass that could easily flip a garbage truck.

 

It was, by all metrics, one of the most overwhelmingly powerful Quirks in existence.

 

And it was a complete nightmare to live with.

 

Vesper had no concept of human morality. The entity operated on a strict, binary code: Protect Host. Consume fuel. To Vesper, the world was divided into two categories: things that were a threat to Izuku (which needed to be destroyed), and things that were food (which needed to be eaten to sustain their immense caloric burn).

 

Izuku had spent the last ten years acting as a cage, a warden, and a teacher to the beast inside him. He had taught Vesper right from wrong, the concept of heroism, and the ironclad rule that they do not harm innocent people, no matter how mean they were. It was a constant, exhausting mental tug-of-war. Izuku had to maintain perfect emotional control. If he panicked, if he got angry, Vesper would sense the spike in adrenaline and take over.

 

And so, Izuku Midoriya became meek. He hunched his shoulders. He kept his head down. He smiled nervously and apologized for everything. He became the quiet, harmless, Quirkless-acting kid, because the alternative was letting the monster out.

 

"Since you're all third years, it's time for you to think seriously about your futures!" the homeroom teacher suddenly announced, slapping a stack of career aptitude tests on his desk. "I'll pass out these handouts, but I know you're all pretty much planning to go into the hero course, right?"

 

The class erupted into cheers, students showing off their Quirks. Water splashed, fingers elongated, small sparks popped in the air.

 

"Yes, yes, you all have wonderful Quirks," the teacher sighed, "but remember, using your powers in school is against the rules."

 

"Hey, Teach! Don't lump me in with these bunch of losers!"

 

The loud, arrogant voice cut through the chatter like a knife. Katsuki Bakugo leaned back in his chair, his feet kicked up on his desk, a sneer plastered across his face. "I'm the real deal. These guys will be lucky to end up as sidekicks to some busted D-lister. I'm going to UA High."

 

The class broke into a mix of awe and indignation. UA was the national school, the Harvard of heroics, with an acceptance rate of less than two percent.

 

Izuku shrank further into his seat. Don't look at me, don't look at me, he prayed.

 

"Oh, right," the teacher said, looking down at his clipboard. "Midoriya, you're applying for UA too, aren't you?"

 

The classroom went dead silent.

 

All eyes slowly turned to the back corner. The look on their faces wasn't mocking, like it might have been if Izuku were Quirkless. It was something much worse. It was abject horror.

 

Bakugo froze. His feet slowly slid off his desk.

 

“The explosive gnat is looking at us,” Vesper hissed in Izuku’s mind, the temperature of Izuku’s blood rising a fraction of a degree. “He smells like burnt sugar and fear. I want to crush him.”

 

No, Vesper. Quiet.

 

"Midoriya?" one of the students whispered, his voice trembling. "In the hero course? With... with that thing?"

"He'd probably eat the villains," another muttered, shivering.

 

Bakugo didn't say a word. In the past, when they were small children, Bakugo had been the king of the playground. He was confident, powerful, and praised by everyone. But Bakugo had been there on the day, years ago, when a stray dog with a rabid Quirk had attacked a group of kids. Bakugo had tried to fight it with his explosions, but the dog had overpowered him.

 

Izuku had stepped in. Or rather, Vesper had.

 

Bakugo had watched, paralyzed, as a massive, horrifying amalgamation of black teeth and tendrils had erupted from "Deku," grabbing the rabid dog and literally tearing it in half, showering the playground in blood. Bakugo had never forgotten the terrifying, hollow white eyes of the black monster as it looked at him, seemingly debating whether Bakugo was dessert.

 

From that day on, Bakugo’s relationship with Izuku changed. He didn't bully Izuku out of a sense of superiority. He bullied Izuku because Katsuki Bakugo was deeply, fundamentally terrified of him, and Katsuki Bakugo only knew one way to deal with fear: violence and rage.

 

The bell rang, saving Izuku from the suffocating silence. He quickly began packing his things, slipping his Hero Analysis for the Future, No. 13 notebook into his yellow backpack. He just wanted to get home. He just wanted to be somewhere quiet.

 

"Deku."

 

Izuku stopped. He looked up. Bakugo was standing by his desk, flanked by two of his lackeys. Bakugo’s red eyes were locked onto Izuku, filled with a volatile mix of hatred and defensive paranoia. Small explosions were popping in the palms of Bakugo’s hands, a nervous tic.

 

"Kacchan," Izuku said softly, his voice even. "Can I help you?"

 

Bakugo snatched the notebook off Izuku’s desk before he could put it away. "Hero Analysis? You've gotta be kidding me."

 

"Give it back, please," Izuku said, trying to keep his heart rate down.

 

“He is touching our property. Kill him,” Vesper urged, a dark shadow momentarily passing over Izuku’s green eyes, turning the sclera pitch black for a fraction of a second before Izuku suppressed it.

 

Bakugo saw the flicker of black in Izuku's eyes. He flinched visibly, taking a half-step back, but his pride forced him forward. He slammed his palms together, detonating a concentrated explosion directly onto the notebook. The smell of burning paper and ash filled the air.

 

"You think you can go to UA, you freak?" Bakugo snarled, though his voice lacked its usual booming confidence. It sounded strained. "Heroes are supposed to save people. They bring peace. You? You're a walking horror movie. The pros would lock you up in Tartarus the second you showed your true colors."

 

Bakugo tossed the smoldering notebook out the open window. It fell out of sight, landing in the koi pond below.

 

"Don't apply to UA, Deku," Bakugo said, leaning in, his breath smelling like nitroglycerin. "Because if you get in my way, I'll blast that black parasite of yours into ash. I don't care what it takes."

 

Izuku just looked at him. He didn't look scared. He looked... tired.

 

"Are you done, Kacchan?" Izuku asked quietly.

 

Bakugo's jaw clenched. The complete lack of fear from Izuku was infuriating. It was a constant reminder of the power dynamic between them. Bakugo turned on his heel. "Let's go. This place stinks of villain."

 

As Bakugo and his lackeys walked away, Izuku sat alone in the empty classroom. He closed his eyes and took a deep, shuddering breath.

 

“Why do we let him live?” Vesper asked, genuine confusion lacing the mental voice. “He is weak. We are apex. I could snap his spine before his brain registered the pain. He threatens us. He burns our belongings. Why, Izuku? Why not let me show him what we really are?”

 

Because, Vesper, Izuku replied, standing up and grabbing his bag, being strong doesn't mean you get to hurt people who are weaker than you. Kacchan is scared. He lashes out because he doesn't understand us. If we hurt him, we prove him right. We prove everyone right.

 

“Fear is respect,” Vesper countered stubbornly.

 

No. Fear is just fear, Izuku corrected patiently, like a father speaking to a toddler. Heroes don't make people afraid. All Might makes people feel safe. When he smiles, people know everything is going to be okay. I want to be like that. I want to save people.

 

Vesper went quiet for a moment, retreating deep into Izuku’s chest. “...Your pulse is sad. I do not like it when your pulse is sad. We will be heroes, Izuku. We will save the meat-bags. Even the explosive one.”

 

Izuku offered a small, weary smile to the empty room. Thank you, Vesper. Let's go home.

 

 

 

The walk home was usually the best part of Izuku's day. It was the only time he was truly alone, free from the scrutinizing eyes of his peers and teachers. He walked under the concrete underpass, a shortcut to his neighborhood, reading the damp, slightly scorched pages of his retrieved notebook.

 

The tunnel was cool and shadowed. The rhythmic echo of his red sneakers against the pavement was the only sound.

 

“Izuku.”

 

Vesper’s voice in his head changed. It wasn't the usual rumbling complaint about hunger or annoyance. It was sharp. Alert. The mental equivalent of a dog’s ears snapping upright.

 

What is it? Izuku asked, pausing mid-step.

 

“Movement. Behind us. Not human. Smells like... rot and sewage.”

 

Before Izuku could turn around, the grate on the sewer manhole ten feet behind him blew off with a metallic clang. A massive wave of dark green, viscous sludge erupted from the darkness. It bubbled and hissed, coalescing into a towering, gelatinous form. Two massive, bulbous eyes and a jagged set of teeth formed in the center of the muck.

 

"A medium-sized invisibility cloak," the Sludge Villain rasped, his voice echoing wetly off the concrete walls. "Perfect. Just what I need to get that giant blonde bastard off my trail."

 

Izuku took a step back, his eyes widening. A villain. A real villain, right here.

 

"Don't worry, kid," the Sludge Villain laughed, lunging forward with terrifying speed. "It'll only hurt for about forty-five seconds. Then, it'll all be over!"

 

The sludge washed over Izuku like a tidal wave. Thick, suffocating muck forced its way into Izuku's mouth and nose. The villain wrapped around him, pinning his arms to his sides, crushing him with immense hydraulic pressure.

 

"That's it, stop struggling," the villain cooed, forcing more sludge down Izuku's throat. "You can't grab me. I'm fluid. Just give me your body."

 

Izuku couldn't breathe. The sludge was filling his lungs. His vision began to spot with black dots. The panic was instantaneous and overwhelming. His heart rate skyrocketed to 180 beats per minute. The carefully constructed mental cage he used to keep his emotions in check shattered completely.

 

And deep within Izuku’s cells, Vesper woke up.

 

The entity did not feel fear. It felt an incandescent, apocalyptic rage. Someone was hurting its host. Someone was invading its territory.

 

“NOBODY.”

 

The voice didn't echo in Izuku's mind this time. It ripped out of Izuku’s throat, a demonic, distorted roar that shook the very foundations of the concrete tunnel.

 

The Sludge Villain froze, his bulbous eyes widening in sudden confusion. "What the hell? What was that?"

 

Izuku’s eyes snapped open. The emerald irises were gone. His eyes were entirely pitch black, devoid of light, like two voids in the center of his face.

 

“TOUCHES.”

 

Black liquid began to seep out of Izuku's pores, mixing with the green sludge. But the black liquid was denser, heavier, and infinitely more violent. It didn't just push the sludge away; it began to assimilate it.

 

"What is this?!" the Sludge Villain shrieked, suddenly realizing that the boy he was trying to possess was rapidly turning into something else. The villain tried to pull away, to detach himself from Izuku, but he couldn't.

 

“OUR.”

 

Massive, obsidian-black tendrils erupted from Izuku’s back, tearing through his middle school uniform. They whipped out, wrapping around the main mass of the Sludge Villain. The tendrils ended in jagged, scythe-like blades that hooked deep into the villain’s gelatinous body.

 

"Let me go!" the Sludge Villain screamed, his previous arrogance entirely replaced by primordial terror. He was no longer the predator. He had just jumped onto the back of an apex monster. "What are you?!"

 

“HOST.”

 

The black biomass surged, completely engulfing Izuku's body. He grew taller, wider. His muscles expanded to grotesque, hulking proportions. The symbiote formed a massive, muscular humanoid shape, easily standing eight feet tall. The face was the stuff of nightmares: smooth and featureless save for two massive, jagged white eyes that conveyed nothing but pure malice, and a jaw that unhinged, revealing rows upon rows of razor-sharp teeth and a long, prehensile, serpentine tongue.

 

Vesper was in complete control.

 

The Sludge Villain was completely immobilized, suspended in the air by Vesper’s immense strength. Vesper gripped the villain with hands the size of manhole covers, the symbiote’s claws digging into the villain's eyes.

 

“You taste like garbage,” Vesper hissed aloud, the voice a terrifying, wet bass that vibrated through the air. “But fuel is fuel.”

 

Vesper’s jaws opened impossibly wide. The symbiote didn't just punch the villain; it began to physically consume him. Vesper bit down on the sludge, the black biomass rapidly breaking down and absorbing the villain's cellular structure.

 

"No! NO! HELP!" the Sludge Villain screamed, thrashing wildly. But his attacks simply bounced off Vesper’s armored hide. Vesper began slurping the sludge into its maw, violently sucking the villain into its own mass. With every bite, Vesper grew slightly larger, the black liquid undulating and shifting with sickening fluidity.

 

No, Vesper! Stop! Izuku's voice echoed from deep within the mental void. You're going to kill him!

 

“He tried to kill us,” Vesper countered, taking another massive bite of the sludge, ignoring the villain's agonized shrieks. “He is meat. We are hungry.”

 

We are not a murderer! Izuku screamed in his mind, fighting with all his willpower to regain control of his nervous system. If you kill him, I will never let you have katsudon again! I will starve us both! Let him go!

 

Vesper paused. The massive, terrifying jaws snapped shut, leaving the Sludge Villain—now reduced to a pitiful, quivering puddle of muck with two terrified eyes—dangling from a single black tendril.

 

“...Fine,” Vesper grumbled, sounding distinctly like a petulant child denied a toy. “Host is too soft. But I am keeping the mass I already ate.”

 

The massive, hulking black creature let out a disappointed sigh that sounded like a steam release valve. Vesper forcefully slammed the remaining puddle of the Sludge Villain into the concrete wall, knocking the villain completely unconscious.

 

As the villain went limp, the towering black monster stood in the center of the tunnel, panting, its long tongue licking the remnants of green sludge from its jagged teeth.

 

Suddenly, a loud CLANG echoed from the sewer entrance.

 

"HAVE NO FEAR, CITIZEN!" a booming, legendary voice echoed through the tunnel. "FOR I AM—"

 

All Might, the Symbol of Peace, the Number One Hero in the world, burst from the sewer, his fist drawn back, ready to unleash a devastating Texas Smash. He had tracked the villain through the city, ready to save the day.

 

But All Might stopped dead in his tracks.

 

The tableau before him defied all logic. There was no hostage. There was no rampaging Sludge Villain.

 

Instead, standing under the flickering fluorescent light of the overpass, was a towering, eight-foot-tall demon made of shifting black liquid. It had muscles upon muscles, terrifying white eyes, and a maw of teeth that looked like shattered glass. The unconscious, defeated remains of the Sludge Villain were pinned to the wall by a massive, spiked tendril extending from the demon's back.

 

All Might, veteran of a thousand battles, felt a cold bead of sweat roll down his temple. Every instinct in his body screamed that the creature in front of him was an Omega-level threat. He braced his legs, preparing to go Plus Ultra, ready to fight for his life.

 

"What in the name of..." All Might whispered, his blue eyes narrowing.

 

The black monster turned to look at All Might. It tilted its head.

 

And then, the most bizarre thing happened. The terrifying, jagged teeth receded. The massive muscles deflated, melting like wax. The pitch-black armor peeled back from the top down, slithering over the shoulders and retracting into the skin of the person underneath.

 

Within three seconds, the horrifying demon was gone.

 

Standing in its place was a fourteen-year-old boy. He was wearing a shredded middle school uniform, his curly green hair a mess, his face pale and freckled. He was holding a burnt, soggy notebook in one hand, and he looked absolutely mortified.

 

Izuku Midoriya blinked, looking up at his lifelong idol. His jaw dropped.

 

"Oh," Izuku squeaked, his voice cracking. He nervously rubbed the back of his neck, where the last remnants of the black liquid were soaking into his skin. "Um. Hello, All Might."

 

All Might stood frozen, his fist still raised, his jaw slightly slack. He looked at the boy. He looked at the desiccated, traumatized Sludge Villain. He looked back at the boy.

 

"Young man," All Might said, his booming voice tinged with genuine disbelief. "Did you... did you just eat a villain?"

 

Izuku flushed bright red, waving his hands frantically in the air. "N-no! Well, I mean, technically yes, but not on purpose! My Quirk just—he gets really overprotective, and I told him to spit it out, and—" Izuku buried his face in his hands, groaning in despair. "I'm so sorry. Please don't arrest me."

 

“The large blonde man looks strong,” Vesper’s voice rumbled happily in Izuku’s head. “Can we eat him next?”

 

NO! Izuku mentally shrieked.

 

All Might slowly lowered his fist, staring at the stuttering, panicking boy. The Number One hero had seen many things in his long career, but he had never seen a Quirk with such terrifying, destructive power wielded by someone so completely, painfully gentle.

 

All Might let out a booming laugh, though it was slightly strained. "Well! I suppose I must thank you for subduing the villain, young man! Though your methods are... quite unique!"

 

All Might reached into his pocket, pulling out two large, empty soda bottles he had picked up from a convenience store. In a blur of motion, he scooped up the unconscious Sludge Villain, sealing the remnants inside the bottles.

 

"A job well done!" All Might declared, turning back to Izuku. "Now, I must get this villain to the police. Stay safe, young citizen!"

 

All Might crouched, preparing to leap away.

 

"Wait!" Izuku yelled, reaching out. He couldn't let his idol leave. Not yet. He had to know. He had to ask the question that had plagued him for ten years. The question he needed answered before he applied to UA High. "Please, All Might! Just one question!"

 

All Might paused. He looked back at the boy. There was a desperation in Izuku's green eyes that gave the hero pause.

 

"Make it quick, young man!" All Might said, forcing his trademark smile. "Time is of the essence!"

 

Izuku swallowed hard. He looked down at his own hands. He could see the faint, black veins pulsing beneath his skin—Vesper, listening, waiting.

 

"My whole life," Izuku began, his voice trembling, "everyone has told me that my Quirk is a villain's Quirk. They tell me I'm a monster. That I'm dangerous. And... they're right. My power hurts people. It's violent. It doesn't want to save anyone, it just wants to consume."

 

Izuku looked up, tears brimming in his eyes. "So I have to know. Even with a Quirk like mine... even if I look like a monster... can someone like me ever become a hero? Can I be someone who saves people with a smile, like you?"

 

The silence in the tunnel was deafening.

 

“Why do we ask the blonde meat-bag?” Vesper whispered in his mind. “We do not need his permission. We are stronger than him.”

 

Be quiet, Vesper. Please.

 

All Might stared at the boy. He remembered the sheer, unadulterated terror he had felt upon seeing the black monster just moments ago. He remembered the lethal efficiency with which the boy had subdued a villain that had managed to evade All Might himself.

 

But looking at Izuku now, All Might didn't see a monster. He saw a frightened kid, carrying a burden far too heavy for his small shoulders. He saw a boy who had absolute, god-like power at his fingertips, but chose to hold it back because he valued the safety of others over his own freedom.

 

That restraint... that moral compass in the face of absolute power... that was the essence of a true hero.

 

Suddenly, a sharp pain shot through All Might's side. His time limit was rapidly approaching. A puff of steam rose from his collar. He needed to leave, now, before he reverted to his weakened, skeletal form.

 

"Young man," All Might said, his voice dropping its booming, theatrical edge, becoming deeply sincere. "A Quirk does not dictate the heart of the person who wields it. A sword can be used to kill, or it can be used to protect."

 

All Might pointed a massive finger at Izuku's chest.

 

"You did not let your power consume you. You used it to protect yourself, and you showed mercy to a villain who showed you none. That requires a strength of character that many pro heroes lack."

 

Izuku's breath hitched. The tears he had been holding back finally spilled over his cheeks.

 

"Yes," All Might said firmly, a gentle smile crossing his face. "I believe you can become a hero."

 

With those words, All Might leaped into the air, rocketing out of the tunnel and into the sky, leaving a massive shockwave in his wake.

 

Izuku stood alone in the tunnel, the wind whipping his curly hair around his face. He fell to his knees, clutching his chest, sobbing uncontrollably. The words he had waited ten years to hear washed over him, breaking the dam of anxiety and self-doubt he had built around his heart.

 

Deep inside him, Vesper felt the emotional shift. The entity didn't quite understand the complex human emotion of relief, but it felt the warmth radiating from its host.

 

“The blonde one spoke true,” Vesper grumbled softly. “We are apex. We will be the greatest heroes. And we will eat anyone who tries to stop us.”

 

Izuku let out a wet laugh, wiping his eyes with the back of his hand. No eating people, Vesper.

 

“...Fine. But we are getting katsudon tonight. Double portion. I earned it.”

 

Izuku stood up, a new light shining in his emerald eyes. The fear that had dictated his life for the past decade was gone. He looked at his own hand, willing the black biomass to surface. It didn't erupt violently this time. It seeped out gently, wrapping around his fingers like a sleek, black glove, warm and familiar.

 

Yeah, Izuku thought, a determined smile crossing his face. We earned it.

 

Together, the boy and the monster walked out of the tunnel, stepping out of the shadows and into the sunlight. The journey to UA High had officially begun.

 

The wind screamed past Toshinori Yagi’s ears as he vaulted over the skyline of Musutafu, his massive, muscular frame cutting through the air like a golden missile. Normally, the sensation of flight—the brief moments of weightlessness between his city-shattering leaps—brought him a sense of profound peace. But today, his mind was a turbulent storm, his thoughts entirely consumed by the fourteen-year-old boy he had just left behind in a dark, concrete underpass.

 

Izuku Midoriya.

 

All Might landed heavily on the roof of a three-story office building, the reinforced concrete spider-webbing beneath his boots. He crouched, catching his breath as a sharp, familiar spike of agony radiated from his left side. He clutched his ribcage, gritting his teeth against the pain, but his mind quickly drifted back to the boy.

 

He had spent five years searching for a successor. Nightai’s grim prophecy loomed over him, a ticking clock counting down to his inevitable, gruesome demise. He needed someone to inherit One For All, someone with a pure, unflinching heroic spirit. He had considered top students, prodigies with exceptional Quirks, but none had felt right.

 

Then, he met a boy who commanded a nightmare.

 

Toshinori couldn’t shake the visceral image of the monstrous, eight-foot-tall demon made of black, liquid abyss. The sheer, overwhelming power radiating from that entity was staggering. It wasn’t just physical strength; it was an aura of apex dominance, a primal, predatory weight that made even the Number One Hero’s instincts scream in alarm. If that creature had wanted to level the city block, Toshinori wasn't entirely sure he could have stopped it before his time limit ran out.

 

And yet, that terrifying, god-like power was bound to a boy who stuttered, cried, and carried a ruined, burnt notebook. A boy who held the beast back with nothing but sheer moral fortitude.

 

“My power hurts people. It’s violent. It doesn’t want to save anyone, it just wants to consume. Can someone like me ever become a hero?”

 

Toshinori let out a heavy sigh, a puff of white steam escaping his lips. "You already are a hero, Young Midoriya," he murmured to the empty rooftop. "To have the power of a villain, the strength of a god, and yet choose the path of a protector... that requires a heart stronger than any muscle."

 

Suddenly, a violent spasm wracked Toshinori’s body. He coughed, a splatter of dark blood hitting his massive hand. His vision swam.

 

No, not yet, he thought, panic seizing him. I have another ten minutes!

 

But his body disagreed. The adrenaline from the Sludge Villain chase had masked his exhaustion, and the shock of seeing Midoriya’s Quirk had pushed his strained system past its breaking point. The steam billowing from his skin grew exponentially thicker, hissing like a broken radiator.

 

Toshinori staggered forward, grasping at his cargo pants. The two large plastic soda bottles containing the liquid remains of the Sludge Villain knocked against his thigh. He needed to get them to the police precinct immediately. He bent his knees, preparing for one final, desperate leap.

 

Cough!

 

A second, more violent spasm hit him mid-jump. The pain was blinding, a white-hot knife twisting into his missing respiratory organs. His trajectory faltered. He clipped the edge of a billboard, tumbling through the air as his muscular form finally, violently deflated.

 

In a cloud of smoke, the towering Symbol of Peace was replaced by a skeletal, emaciated man in clothes three sizes too big. Toshinori plummeted toward a narrow alleyway, bouncing off a fire escape and crashing painfully into a pile of cardboard boxes.

 

He lay there for a moment, groaning, his skeletal chest heaving as he wiped blood from his chin. "Damn it..." he wheezed, his limbs feeling like lead. "That... was undignified."

 

He forced himself to sit up, patting his incredibly baggy pockets.

 

His heart stopped.

 

His pockets were empty.

 

Toshinori’s sunken blue eyes widened in sheer, unadulterated horror. He scrambled onto his hands and knees, frantically searching the alleyway, throwing empty boxes and trash bags aside.

 

"No, no, no, no..." he muttered, his breath coming in short, panicked gasps.

 

He looked up at the sky. During his fall, the bottles must have slipped from his pockets. They could have landed anywhere in the densely populated commercial district below. A villain with a fluid body, capable of suffocating a victim in seconds, was now loose in the city. And All Might, the great Symbol of Peace, had no time left, no power to stop him.

 

A deep, sickening sense of dread settled in Toshinori’s hollow stomach. He had made a terrible, terrible mistake.

 

 

 

A mile away, Izuku Midoriya was walking with a spring in his step that hadn't been there in ten years.

 

The afternoon sun painted the streets of Musutafu in warm hues of orange and gold. The air smelled of exhaust fumes and blossoming trees, but to Izuku, it was the sweetest air he had ever breathed. He felt completely untethered, as if a massive, suffocating weight had finally been lifted from his shoulders.

 

He said yes, Izuku thought, a dizzying, euphoric smile plastered across his freckled face. All Might said I can be a hero. He looked at me, he saw Vesper, and he didn't tell me I was a monster.

 

Deep within the dark, warm cavern of Izuku’s circulatory system, Vesper hummed. It was a strange sensation—like the purring of a massive, contented jungle cat vibrating against Izuku’s ribs.

 

“The large blonde one was wise,” Vesper’s voice echoed in Izuku’s mind, sounding remarkably smug for a puddle of sentient alien biomass. “He recognized our superiority. It is good that we did not eat him. He may prove useful.”

 

He’s the Number One Hero, Vesper, Izuku replied mentally, swinging his yellow backpack over his shoulder. He’s not 'useful', he's the Symbol of Peace! He saves thousands of people!

 

“We will save more,” Vesper declared matter-of-factly. “We are faster. We do not need to punch the air to move. And we can consume the threats. It is highly efficient.”

 

Izuku sighed, though he was still smiling. We’ve talked about this. Heroes arrest villains. They don't eat them. If you eat people, society locks you up in Tartarus.

 

“They can try,” Vesper rumbled, a dark amusement lacing its telepathic voice. “I would enjoy the exercise. I could break their concrete boxes like eggshells.”

 

No breaking boxes. No eating villains. We have rules, Vesper.

 

“Rules are for prey,” the symbiote grumbled, retreating slightly into Izuku’s subconscious. “...But I will follow the Host’s rules. For now. Because the Host promised katsudon.”

 

Izuku laughed aloud, a genuine, joyful sound that earned him a strange look from a passing businessman. For the first time in his life, Izuku felt like he and Vesper were truly on the same page. They weren't a boy holding a monster captive; they were partners. Two minds, one body, walking the same path.

 

As Izuku approached the Tatooin Shopping District, his stomach gave a loud rumble.

 

“Yes. Fuel. The Host requires sustenance,” Vesper chimed in immediately. “Perhaps a preliminary snack before the katsudon? I smell heavily processed carbohydrates and cooked animal fat nearby.”

 

A meat bun wouldn't hurt, Izuku agreed, reaching into his pocket for his wallet.

 

Before his fingers could grasp the leather, a deafening explosion shattered the peaceful afternoon.

 

BOOM!

 

The ground beneath Izuku’s feet trembled. A shockwave rattled the glass windows of the nearby storefronts, followed by the terrifying sound of twisting metal and shattering concrete.

 

Izuku froze. His hero instincts, honed by years of obsessive analysis and suppressed desires, flared to life. He looked down the street. Plumes of thick, black smoke were billowing into the sky from the center of the shopping district. Screams echoed from the crowd ahead as people began to flee in the opposite direction.

 

“Danger,” Vesper hissed. The purring ceased instantly. Izuku’s blood ran cold, then immediately flushed with an unnatural heat as the symbiote prepared for combat. “Host, there is a threat ahead. I sense fire. I do not like fire.”

 

Someone might be hurt, Izuku thought, his legs already moving on their own. He didn't run away with the crowd; he sprinted toward the smoke.

 

“Wait. Izuku, halt.” Vesper’s voice was sharp, analytical. A tiny tendril of black liquid slipped out from the collar of Izuku’s shirt, forming a microscopic sensory organ near his nose. “I recognize this chemical scent. Nitroglycerin. Burnt sugar. Sweat.”

 

Izuku’s eyes widened. Kacchan.

 

He pushed through the panicked crowd, apologizing as he bumped into shoulders, driven by a sudden, sickening panic. He rounded the corner into the main plaza of the shopping district, and the breath left his lungs.

 

It was a warzone.

 

Fires raged across the alleyway, licking the sides of the buildings. A crushed city bus blocked the intersection. But that wasn't what made Izuku’s stomach drop.

 

In the center of the inferno, towering above the flames, was a massive, bubbling mound of dark green sludge. The Sludge Villain. The very same villain Vesper had nearly consumed under the bridge less than an hour ago.

 

How? Izuku thought, paralyzed. All Might captured him! How is he here?!

 

"Stay back!" the Pro Hero Death Arms shouted, holding his massive arms out to keep the crowd at bay. "It's too dangerous!"

 

"I can't get in close!" Kamui Woods grunted, his wooden branches retracting as the flames licked at them. "My wood will catch fire! I need a water Quirk, or someone who can blow away the flames!"

 

"I need at least a two-lane road to get through!" Mt. Lady complained, standing uselessly at the edge of the street in her giant form.

 

Izuku stared at the heroes. They're just... standing there? Why aren't they doing anything?

 

Then, Izuku heard it. A muffled, desperate, gargling scream.

 

He looked closer at the center of the Sludge Villain. Trapped within the viscous, suffocating muck was a boy in an Aldera Junior High uniform. Ash-blonde hair. Furious, tear-filled red eyes.

 

Katsuki Bakugo was drowning.

 

The villain had forced his way into Bakugo’s mouth and nose. In his sheer, unadulterated panic, Bakugo was firing off massive explosions from his palms, trying to blast the villain away. But the explosions only fueled the fires around them, making it impossible for the heroes to approach, and the sludge simply absorbed the kinetic impact.

 

"Damn it, this kid's Quirk is incredible!" the Sludge Villain cackled, his wet voice echoing over the roar of the flames. "Once I take over his body, I'll have enough firepower to blow that blonde muscle-head to pieces! Just give up, kid! It'll be over soon!"

 

Bakugo thrashed violently, but his movements were growing sluggish. His explosions were getting weaker. He was running out of oxygen.

 

In the crowd, standing just a few feet away from Izuku, a skeletal man clutched his stomach. Toshinori Yagi stared at the scene in absolute horror. He gripped a telephone pole so tightly his knuckles bled.

 

It’s my fault, Toshinori thought, self-loathing drowning him. I dropped the bottle. And now, I’m useless. I’m out of time. I can’t even maintain my muscle form for a second. Pathetic... I'm pathetic...

 

Izuku couldn't hear Toshinori's thoughts. The entire world had narrowed down to the sight of Katsuki Bakugo’s eyes.

 

For ten years, Bakugo had looked at Izuku with nothing but hatred, arrogance, and fear. But right now, as the life was being squeezed out of him, Bakugo’s red eyes met Izuku’s green ones through the smoke. And for the first time in his life, Katsuki Bakugo looked like he was pleading for help.

 

“The explosive gnat is dying,” Vesper stated coldly. “He has been a nuisance to us. Let the green puddle consume him. It solves two problems for the Host.”

 

The logic was flawless. It was cold, brutal, and entirely alien.

 

But Izuku Midoriya was not alien. He was human. And he had the heart of a hero.

 

No, Izuku thought, his jaw clenching.

 

Before his brain could process what he was doing, before he could calculate the risks or worry about the Pro Heroes watching, Izuku’s legs moved.

 

He burst past Death Arms, ducking under the hero's outstretched arm, and sprinted headlong into the inferno.

 

"Hey! Kid! Stop! Are you crazy?!" Death Arms roared, reaching out to grab him, but he was too slow.

 

"Midoriya?!" Bakugo’s muffled, gargled voice managed to choke out through the sludge.

 

Izuku ran through the intense heat. The flames licked at his skin, but he didn't feel them. A sudden, chilling wave of absolute focus washed over him. The fear was gone. The hesitation was gone.

 

“Host?” Vesper asked, surprised by the sudden, overwhelming surge of determination radiating from Izuku’s mind.

 

Vesper, Izuku commanded, his mental voice ringing like struck steel. We are saving him. Right now.

 

For a fraction of a second, the symbiote hesitated. And then, it felt the sheer, intoxicating willpower of its host. The entity thrilled at the command.

 

“Understood. Initiating combat sequence.”

 

As Izuku closed the distance, the transformation began. It wasn't the chaotic, monstrous explosion of rage that had happened under the bridge. This was controlled. This was tactical. This was a symphony of violence directed with absolute precision.

 

Pitch-black, liquid-like biomass erupted from Izuku's back and shoulders. It didn't engulf his whole body; instead, it rapidly hardened into sleek, jagged armor plating over his chest, shoulders, and arms. His forearms swelled immensely as the black sludge wrapped around them, transforming his hands into massive, terrifying, three-fingered claws tipped with foot-long scythes of hardened obsidian bone.

 

The heat of the surrounding fire began to irritate the symbiote. Vesper let out a low, bone-rattling hiss that echoed over the roaring flames.

 

The Sludge Villain looked down, expecting to see a foolish child throwing a backpack. Instead, his bulbous eyes widened in absolute, paralytic terror.

 

He recognized the black mass. He recognized the hiss.

 

"You!" the Sludge Villain shrieked, his voice cracking with trauma. "No! Not you! Stay away from me!"

 

"Deku?!" Bakugo gasped, staring in shock as the boy he had bullied for a decade charged at him, looking like a heavily armored demon of vengeance.

 

Izuku didn't say a word. He didn't need to.

 

He planted his foot into the asphalt, cracking the pavement beneath him. Using the immense, enhanced musculature of the symbiote armor, Izuku launched himself into the air, closing the final ten feet in a literal blink of an eye.

 

SWIPE.

 

Izuku swung his massive, black-clawed right hand. He didn't aim for Bakugo. He aimed for the thickest concentration of the sludge holding the blonde boy captive.

 

The sheer kinetic force of the swing created a localized shockwave. The wind pressure alone blew the surrounding fires backward. The razor-sharp symbiote claws didn't just cut the sludge; they literally tore the villain's fluid structure apart at a molecular level.

 

"GAAAAAH!" the Sludge Villain screamed as a third of his body mass was violently sheared off and splattered against a nearby brick wall.

 

With his left hand, Izuku plunged his armored fingers directly into the villain's center mass. He grabbed the collar of Bakugo’s uniform.

 

“Rip and tear,” Vesper purred darkly in his mind.

 

No tearing Kacchan! Izuku snapped back. Just pull!

 

With a terrifying flex of his symbiote-enhanced bicep, Izuku ripped Katsuki Bakugo entirely out of the Sludge Villain's grip. The villain tried to hold on, thick strands of sludge clinging to Bakugo’s legs, but Izuku’s sheer, overwhelming physical strength was insurmountable. The sludge snapped like wet string.

 

Izuku landed heavily on his feet, pulling Bakugo behind him, shielding the coughing, gasping boy with his own body.

 

"My... my prize!" the Sludge Villain wailed, trying to reform his scattered body. Desperation and fear drove him to madness. He reared back, preparing to slam his entire remaining mass down onto Izuku like a tidal wave. "I'll kill you! I'll kill you both!"

 

Izuku stood his ground. The armor plating on his shoulders shifted, growing thicker, heavier. He prepared to unleash Vesper fully, ready to absorb the kinetic impact and consume the villain right in front of the heroes.

 

Suddenly, a shadow fell over them.

 

"I AM PATHETIC."

 

The voice boomed like thunder, shaking the very earth.

 

Izuku looked up. Plunging from the sky, having forced his emaciated body to ignite the embers of One For All one last time, was All Might. The Number One Hero was bleeding from the mouth, his muscles bulging with impossible, destructive tension.

 

"I TOLD YOU WHAT MAKES A CHAMPION, YET I DID NOT ACT ON MY OWN WORDS!" All Might roared, drawing his right arm back. Blood sprayed from his lips, but his blue eyes burned with the fury of a dying sun.

 

"PROS ARE ALWAYS RISKING THEIR LIVES!"

 

DETROIT...

 

The Sludge Villain looked up, his bulbous eyes shrinking to pinpricks. "No... wait..."

 

SMASH!!!

 

All Might drove his fist downward. He didn't even hit the villain directly. He punched the air above the street.

 

The resulting shockwave was apocalyptic.

 

The sheer force of the air pressure obliterated the remaining structure of the Sludge Villain, scattering his fluid body into thousands of harmless droplets across the street. But it didn't stop there. The punch created an updraft of such immense power that it blew out every single fire in the alleyway simultaneously.

 

The wind pressure was so intense that it threatened to blow Bakugo and the surrounding heroes away. But Izuku stood firm. Vesper instantly reacted, dropping massive, heavy anchors of black biomass from Izuku’s calves into the concrete below, locking them in place. Izuku leaned forward, shielding Bakugo from the hurricane-force winds with his armored back.

 

And then, as quickly as the chaos had begun, it was over.

 

The winds died down. The fires were gone. A gentle rain began to fall from the sky—All Might’s punch had literally changed the weather, forcing the rising air to condense into clouds.

 

In the center of the cratered street stood All Might, his fist still planted on the ground, steam rolling off his massive shoulders.

 

Behind him, Izuku Midoriya took a deep breath.

 

It’s over, Izuku thought, his heart rate finally slowing down. We did it.

 

“That... was an acceptable display of violence,” Vesper conceded. “The blonde meat-bag punches hard. But I could punch harder.”

 

Izuku smiled weakly. Sure you could, Vesper.

 

Izuku commanded the symbiote to retreat. The massive black claws dissolved, liquefying and slithering rapidly back up his arms, sinking seamlessly into his skin through his pores. Within seconds, the terrifying armor was gone, leaving only a slightly singed middle school student standing in the rubble.

 

Izuku turned around. Bakugo was sitting on the ground, coughing up remaining bits of sludge, his chest heaving as he dragged in lungfuls of oxygen. His red eyes stared up at Izuku, wide, trembling, and utterly unreadable.

 

For the first time, Bakugo didn't yell. He didn't ignite an explosion. He just stared at the hand Izuku tentatively held out to him.

 

Bakugo slapped Izuku’s hand away, forcing himself up on shaky legs. He didn't say 'thank you'. But he didn't say 'die', either. He simply looked away, his pride shattered into a million irreparable pieces.

 

Before Izuku could say anything, the Pro Heroes swarmed them.

 

 

 

The aftermath was exactly what Izuku had feared.

 

While Bakugo was treated by paramedics and praised by Death Arms and Kamui Woods for his "incredible Quirk" and "amazing endurance," Izuku was cornered by Mt. Lady and a furious Death Arms.

 

"What were you thinking, kid?!" Death Arms scolded, pointing a stern finger at Izuku's chest. "You could have gotten yourself killed! Or worse, gotten in our way! You don't just run into a hostage situation without a license!"

 

"That Quirk of yours..." Mt. Lady muttered, looking at Izuku with a mixture of suspicion and unease. "It looked... volatile. What is it? Some kind of shadow manifestation? It looked like you were going to tear that villain apart."

 

“Let me out,” Vesper hissed venomously in Izuku’s mind. “I will tear their vocal cords out. They stood by while the explosive one died, and now they lecture us? Hypocrites. Meat.”

 

No, Vesper. Stay quiet, Izuku pleaded silently.

 

"I'm sorry," Izuku bowed deeply, his voice returning to its usual meek, stuttering tone. "I didn't mean to interfere. I just... my legs moved on their own. I couldn't just watch him die."

 

"Leave the hero work to the heroes, kid," Death Arms sighed, though the harshness had left his voice. "Just... go home. And be careful with that Quirk. It's not something to throw around lightly."

 

Izuku nodded, turning away. He felt a pang of unfairness, but he pushed it down. He had saved Kacchan. That was all that mattered.

 

The sun was setting by the time Izuku finally managed to slip away from the police statements and the glaring eyes of the Pros. The sky was a bruised purple, and the streets were quiet as he took the long way back to his apartment complex.

 

He felt physically exhausted. Controlling Vesper, especially during a partial manifestation that required precise armor and weaponry rather than just a mindless, hulking form, burned an immense amount of calories. His stomach rumbled violently.

 

“Katsudon. Now. I require fifty bowls.”

 

Mom is making it right now. We'll be home in ten minutes, Izuku promised, rubbing his tired eyes.

 

"I AM HERE!"

 

Izuku shrieked, nearly jumping out of his skin. He spun around, his fists raised, tiny black tendrils instinctively darting out of his knuckles.

 

All Might dashed out from a nearby alleyway, skidding to a halt right in front of Izuku. The massive hero struck a dramatic pose, his teeth gleaming in the fading light. "Hah hah hah! Looking for me, Young Midori— Blergh!"

 

Before All Might could finish his sentence, the massive hero violently spewed a geyser of blood from his mouth. A massive cloud of white steam exploded outward, enveloping him completely.

 

Izuku screamed again, taking a step back as the smoke cleared.

 

Standing where the Number One Hero had been just a second ago was the skeletal, emaciated man with sunken blue eyes and clothes hanging off his frame like a scarecrow.

 

Izuku’s jaw hit the floor. His brain entirely short-circuited. "W-what?! Who... where did All Might go?! Are you a deflating Quirk?! An imposter?!"

 

“...The large blonde meat-bag is broken,” Vesper observed, sounding deeply disappointed. “He is hollow. All bone, no meat. I do not want to eat him anymore.”

 

"I am All Might," the skeletal man sighed, wiping a trickle of blood from his chin. He sat down heavily on the railing of the sidewalk, groaning as his joints popped. "This... is my true form."

 

Izuku stared, his green eyes wide with shock. He couldn't process it. The man who had saved the city, the man who had just changed the weather with a single punch, was this frail, sickly ghost.

 

Toshinori pulled up his oversized white t-shirt, revealing the entire left side of his torso. Izuku gasped. The flesh was sunken and horribly scarred, a massive, spider-webbing crater that looked like it had been carved out by a meteor.

 

"Five years ago, an enemy did this to me," Toshinori said quietly, his voice lacking the booming resonance, replacing it with a weary, grave baritone. "My respiratory system was nearly destroyed. I lost my stomach. I've had repeated surgeries, but the damage is permanent. Right now, I can only do hero work for about three hours a day. The rest of the time... I look like this."

 

Izuku’s hands flew to his mouth. "Five years ago... was that the fight with Toxic Chainsaw?"

 

"You know your history," Toshinori offered a weak, melancholic smile. "But no. That punk couldn't scratch me. This was a fight hidden from the public. A true terror."

 

Toshinori let his shirt fall back down. He looked directly at Izuku, his sunken blue eyes piercing through the twilight.

 

"Young Midoriya. I came here to thank you. And to apologize."

 

"Apologize?" Izuku stammered. "For what? You saved us!"

 

"No," Toshinori shook his head. "If I had not dropped those bottles in my weakened state, that villain would never have been free. And when the time came to act, I stood in the crowd, too pathetic, too consumed by my own weakness to save that boy."

 

Toshinori leaned forward, his gaze intense. "But you... you didn't hesitate. You, with a Quirk that the public deems a nightmare. A Quirk that must terrify you to use. You charged into the fire, risking public backlash, risking your own life, because someone needed you."

 

Toshinori stood up, his tall, skeletal frame casting a long shadow.

 

"You taught me something today, Young Midoriya. You reminded me what a true hero looks like. It is not about the strength of the Quirk. It is about the spirit that drives it."

 

Izuku felt the tears welling up in his eyes again. He couldn't speak. He just listened.

 

"I have been looking for a successor," Toshinori said softly. "Someone to take my place when I can no longer fight. I possess a Quirk that can be passed down like a sacred torch. It is called One For All."

 

Izuku’s analytical mind spun. A Quirk that can be passed down? Is that how he's so strong? But... why is he telling me this?

 

"Before today, I was searching for a vessel," Toshinori continued, stepping closer. "But after seeing what you harbor inside of you... I realize that offering you my power would be foolish. You already possess the strength to shatter mountains. You have an entity within you that is, quite frankly, terrifying."

 

Deep inside, Vesper preened at the compliment. “He understands. We are terrifying.”

 

"But immense power without guidance is a tragedy waiting to happen," Toshinori said, placing a surprisingly warm, skeletal hand on Izuku’s shoulder. "A boy with a 'villainous' Quirk, possessing that level of absolute, destructive force... the world will fear you, Midoriya. The Pros will doubt you. Society will look at you and see a monster."

 

Izuku looked down, his heart aching. He knew it was true. He had lived it his whole life.

 

"Unless," Toshinori said, his voice hardening with conviction, "you have someone to show you how to walk in the light. Someone to teach you how to smile in the face of fear. Someone to help you master the beast, so that it becomes a shield for the innocent."

 

Toshinori dropped to one knee, bringing himself down to Izuku’s eye level.

 

"I cannot give you my Quirk, Izuku Midoriya. You do not need it. But I can give you my experience. I can give you my knowledge. I can train you, guide you, and stand by your side."

 

All Might smiled—not the booming, theatrical grin of the Symbol of Peace, but a gentle, deeply human smile.

 

"Will you allow me to be your mentor? Will you let me help you become the greatest hero this world has ever seen?"

 

The tears spilled over. Izuku fell to his knees on the concrete, the sheer magnitude of the offer crushing the breath from his lungs. The Number One Hero. His idol. The man who stood at the pinnacle of society, was asking to train him. The boy with the villain Quirk.

 

Izuku looked up at Toshinori, his green eyes burning with an unshakeable, fiery resolve. He didn't stutter. He didn't hesitate.

 

"Yes," Izuku choked out, bowing his head. "Yes, please. I'll do whatever it takes. I want to save people. I want to be a hero!"

 

“We will be the strongest,” Vesper echoed in his mind, the symbiote’s dark, violent aura weaving seamlessly with Izuku’s pure, heroic intent. “We will protect the weak. We will destroy the threats. And we will eat the katsudon.”

 

Toshinori laughed gently, a warm, coughing chuckle that filled the quiet evening air. He placed a hand on Izuku's messy green hair.

 

"Then rest well tonight, Young Midoriya. Because starting tomorrow, we begin your journey to UA High. And I promise you, it will be the hardest ten months of your life."

 

Izuku looked up at the darkening sky, the stars just beginning to peek through the clouds left behind by All Might's punch. He felt the terrifying, monstrous power pulsing in his veins, but for the first time, he didn't feel afraid of it.

 

He was Izuku Midoriya. He was Vesper. And together, they were going to change the world.

 

The scent of salt, rotting seaweed, and decades of accumulated industrial rust hung heavy over Dagobah Municipal Beach Park. For years, the shoreline had served as an illegal dumping ground, a monument to society’s laziness. Mountains of broken refrigerators, crushed cars, and shattered electronics obscured the ocean view entirely.

 

To Toshinori Yagi, it was the perfect training ground. To Izuku Midoriya, it was an insurmountable mountain. But to Vesper, it was an all-you-can-eat buffet of crunchy, metallic appetizers.

 

"Ten months!" All Might’s voice boomed, despite his emaciated, skeletal form sitting atop a rusted pickup truck. "The UA Entrance Exam is exactly ten months from today! To the average observer, your Quirk is already at the level of a Pro Hero, Young Midoriya. You have absolute, overwhelming destructive power."

 

All Might paused, coughing a small splatter of blood into a pristine white handkerchief before pointing a bony finger at Izuku. "But! Power without a foundation is a house built on sand! If you rely solely on your... companion... your human body will remain a weak link. To control a beast, you must have the physical fortitude of a titan! Thus, we shall forge your body into an unbreakable vessel!"

 

Izuku stood at the base of a towering pile of trash, wearing a stained gray tracksuit. He looked down at his own thin arms, then up at the impossible mountain of garbage.

 

“The skeletal blonde speaks wisdom,” Vesper’s deep, rumbling voice echoed in Izuku’s mind. “When I exert maximum force, I strain your skeletal structure. Your bones have broken twenty-seven times in the past decade. I heal them, but it is inefficient. I need a sturdier frame to hang my muscle upon.”

 

You don’t have to count the times I break my bones, Vesper, Izuku sighed mentally.

 

"Your goal," All Might continued, hopping down from the truck, "is to clear this entire beach! By hand! You will lift, pull, and drag this trash to the municipal processing center up the road. But there is a catch!"

 

All Might’s blue eyes narrowed sharply. "You are not allowed to use your Quirk to lift the trash. You must use your own, unenhanced human muscles."

 

Izuku blinked, his jaw dropping. "M-my own muscles? But All Might, some of these trucks weigh tons! I can't even lift a microwave without Vesper's help!"

 

“Preposterous,” Vesper hissed, a small puddle of black liquid seeping from Izuku’s collar to form a tiny, angry eye on his shoulder. “I am power. Let me move the garbage. We will be done in four minutes.”

 

"Ah, but I see your passenger is eager!" All Might chuckled, leaning in closer. "No, my boy. If you use the symbiote for everything, your human heart will not grow stronger. However, I have a secondary task for your shadow."

 

All Might tapped a rusted, heavy steel beam lying on the sand. "During my research into Quirks of this nature, I read about biomass entities. They require immense caloric intake to function, correct?"

 

"Yes," Izuku nodded. "Vesper is always hungry. We eat about six meals a day, mostly high-protein meat and carbs. If he doesn't get enough fuel, he starts..." Izuku shivered. "He gets cranky."

 

"Indeed. But what if he didn't just consume organic matter?" All Might suggested, a glimmer of tactical genius in his hollow eyes. "What if he consumed inorganic matter? Metals. Alloys. Titanium."

 

Izuku stared. Can you eat metal, Vesper?

 

“It is lacking in blood and flavor,” Vesper grumbled. “But iron is iron. Minerals fortify my cellular structure. If I consume the metallic waste, I can synthesize it into denser, impenetrable armor plating for our use.”

 

"Exactly!" All Might clapped his hands. "So, the regimen is this: Izuku, you build your cardiovascular endurance and muscle mass by manually hauling the lighter trash. Meanwhile, your companion will consume the heaviest, most dense metals on this beach, effectively digesting the obstacles you cannot move! You train your body; he upgrades his armor!"

 

A slow, determined smile spread across Izuku's face. He looked at the mountain of trash. It didn't look like a burial ground anymore. It looked like the first step to greatness.

 

"Right!" Izuku shouted, slapping his cheeks. "Let's do this!"

 

The next ten months were a blur of absolute, unadulterated agony, blood, sweat, and black sludge.

 

Dagobah Beach became a crucible. Under All Might’s watchful eye, Izuku pushed his human body past its absolute limits. He dragged tires through deep sand until his lungs burned like they were filled with acid. He hauled rusted appliances until his palms blistered and bled.

 

And every time his muscles tore, every time he collapsed into the sand, gasping for air, Vesper was there. The symbiote acted as the ultimate recovery tool, flooding Izuku’s system with hyper-regenerative cells, repairing the torn muscle fibers stronger and thicker than before.

 

But Vesper was working, too. While Izuku hauled, the symbiote detached tendrils of itself, slithering over rusted cars and steel girders. Vesper acted like a localized black hole, its acidic enzymes breaking down iron, steel, and aluminum, drawing the metallic compounds directly into Izuku’s bloodstream.

 

“This tastes like old pennies and failure,” Vesper complained one rainy afternoon in November, dissolving the engine block of a ruined sedan. “I demand pork cutlets as compensation.”

 

Just eat it, Vesper, Izuku thought back, gritting his teeth as he pulled a refrigerator by a rope strapped across his chest. Think about how strong your armor will be.

 

As the seasons changed from autumn to the bitter cold of winter, Izuku began to change. He was no longer the frail, hunched boy who flinched at loud noises. His shoulders broadened. His chest filled out. Under his oversized clothes, his muscles were dense, carved out of grueling labor and symbiote-enhanced recovery.

 

But the most significant change was in his combat training.

 

During their breaks, All Might would assume his muscular form for brief, three-minute intervals to spar with Izuku. It was terrifying, brutal, and essential. All Might taught Izuku how to fight not as a human, but as an apex predator.

 

"You rely too much on brute force!" All Might roared one snowy morning, catching a massive, black-armored punch from Izuku. The shockwave blew the snow off the beach. "Your Quirk can shapeshift! Be fluid! Be unpredictable!"

 

Taking the advice to heart, Izuku didn't pull his fist back. Instead, the symbiote armor on his arm liquefied, slipping out of All Might’s grip like water. In a fraction of a second, the liquid reformed into a hardened, black scythe, hooking behind All Might’s knee to pull him off balance.

 

"Excellent!" All Might laughed, easily backflipping to avoid the sweep.

 

By the time the cherry blossoms bloomed in the final weeks of spring, Dagobah Beach was unrecognizable. The miles of trash were completely gone. The golden sand lay pristine and untouched beneath the morning sun, the gentle ocean waves lapping at the shore.

 

Standing at the edge of the water was Izuku Midoriya. He was shirtless, sweat dripping from his heavily muscled, scarred torso. He let out a primal, echoing scream of triumph to the rising sun, dropping the final piece of trash—an old truck tire—onto the pavement behind him.

 

All Might stood nearby in his true form, his skeletal face stretched into a wide, immensely proud smile.

 

"You did it, Young Midoriya," Toshinori said softly. "You didn't just clear the beach. You built a vessel capable of holding the sea."

 

Izuku turned around, breathing heavily. He looked down at his hands. With a single thought, pitch-black liquid seeped from his pores. But it wasn't the volatile, bubbling muck it used to be. The biomass was sleek, metallic, and smooth, gleaming with a dark, oily sheen. Vesper had consumed hundreds of tons of metal, integrating it into its biology.

 

“We are ready,” Vesper purred, the mental vibration rattling Izuku’s newly fortified ribs. “The prey at the exam will not know what hit them.”

 

Izuku clenched his fist, the black armor hardening into a gauntlet with the density of titanium. He looked up at All Might, his green eyes burning with ten months of unrelenting fire.

 

"I won't let you down, All Might."

 

The morning of the UA Entrance Exam, the Midoriya household was a whirlwind of nervous energy.

 

Inko Midoriya frantically adjusted the collar of Izuku’s black junior high uniform, her hands trembling. "Do you have your pencils? Your eraser? Did you eat enough? I made a double portion of katsudon just like you asked, but maybe you need more carbs for your... for Vesper?"

 

"I'm fine, Mom, I'm fine," Izuku laughed gently, catching his mother's hands. "I'm full. Vesper's full. We're ready."

 

Inko looked up at her son. He was so much taller now, his posture straight, an undeniable aura of quiet confidence radiating from him. She reached up, tears pricking her eyes, and hugged him tightly. "I'm so proud of you, Izuku. Whatever happens today, I love you."

 

"Love you too, Mom."

 

Izuku stepped out of the apartment complex, breathing in the crisp morning air. The walk to the train station felt surreal. Ten years of dreaming, ten years of fear, all culminating in this single day.

 

When he finally stood before the massive, towering glass gates of UA High School, Izuku felt a brief flutter of anxiety. The building was colossal, shaped like a giant 'H', intimidating in its sheer scale. Hundreds of students from across the country were swarming the entrance, chatting nervously.

 

"Out of the way, Deku."

 

The voice was low, devoid of its usual explosive fury, but it still carried a sharp edge.

 

Izuku turned. Katsuki Bakugo was walking up the path behind him, his hands shoved deep into his pockets. He looked away, refusing to make eye contact with Izuku.

 

“The explosive gnat,” Vesper whispered in Izuku’s mind, a dark amusement coloring its tone. “His heart rate elevates when he looks at us. He remembers the fire. He fears the teeth.”

 

Leave him alone, Vesper, Izuku reprimanded gently.

 

"Morning, Kacchan," Izuku said evenly, stepping to the side.

 

Bakugo didn't sneer. He didn't ignite his palms. He simply clicked his tongue, his jaw clenching so hard it looked painful, and walked quickly past Izuku, giving him a wide berth. The days of Bakugo confronting Izuku directly had ended at the Sludge Villain incident. Bakugo had seen the gap between them, and his pride was currently locked in a bitter war with his survival instincts.

 

Izuku watched him go, letting out a soft sigh before taking his first step toward the gates.

 

Whoops.

 

Izuku’s foot caught the edge of a slightly raised paving stone. His center of gravity shifted. Panic briefly flared as he pitched forward, bracing for the embarrassing impact of face-planting in front of the entire student body on his first day.

 

“Clumsy,” Vesper sighed in his mind.

 

Before Izuku could hit the concrete, a microscopic, razor-thin black tendril shot out from the heel of his shoe, anchoring instantly to the pavement and pulling him upright like a puppet on a string. It was so fast, so seamlessly hidden by the shadow of his leg, that no one saw it.

 

Izuku let out a breath of relief, standing upright.

 

"Oh! Are you okay?"

 

A soft, cheerful voice broke his concentration. Izuku turned to see a girl with round, rosy cheeks, warm brown hair cut into a bob, and a remarkably bright smile. She had her hand outstretched, as if she had been trying to catch him.

 

"I was going to use my Quirk to stop you from falling," she laughed lightly, rubbing the back of her head. "It's my Quirk, Zero Gravity! It would be bad luck to fall on exam day, right? But it looks like you caught yourself! You've got great reflexes!"

 

Izuku stared at her, his face instantly erupting in a violent blush. A girl. A cute girl. A cute girl was talking to him.

 

“Her cheeks are pink,” Vesper observed clinically. “She smells like strawberries and ozone. Can we bite her?”

 

NO! Izuku shrieked internally, his face turning an even deeper shade of red. Absolutely not! She’s nice!

 

"I-I-I, um, yeah! Yes! Reflexes! I have those! Thank you!" Izuku stammered, waving his hands frantically, completely reverting to his old, anxious self.

 

The girl giggled, the sound light and airy. "Well, good luck today! Let's both do our best!" She waved cheerfully and jogged off toward the entrance.

 

Izuku stood frozen, watching her go. I talked to a girl...

 

“You did not talk,” Vesper corrected dryly. “You made distressed noises. It was pathetic. Let me handle the mating rituals from now on. I will bring her a severed head to show our strength.”

 

I am begging you to never, ever do that, Izuku groaned, covering his face with his hands before hurrying inside.

 

The written exam went smoothly. Izuku had spent years analyzing Quirks and hero laws; the test was practically second nature. But it was the orientation for the practical exam that sent his adrenaline spiking.

 

Izuku sat in the massive, dimly lit auditorium, surrounded by hundreds of applicants. Up on the stage, the Voice Hero: Present Mic, was explaining the rules of the physical test.

 

"LIKE I SAID, LISTENERS!" Present Mic shouted, posing dramatically. "YOU'LL BE CONDUCTING TEN-MINUTE MOCK URBAN BATTLES! YOU'LL BE FIGHTING THREE TYPES OF FAUX VILLAINS, WORTH ONE, TWO, AND THREE POINTS RESPECTIVELY! USE YOUR QUIRKS, DESTROY THE ROBOTS, AND RACK UP THOSE POINTS!"

 

Izuku frantically scribbled in a new notebook. Robots. Non-organic. No collateral damage restrictions. Vesper can go all out.

 

"Excuse me! May I ask a question?!"

 

A tall boy with severe glasses and stiff, robotic posture stood up a few rows ahead of Izuku. A spotlight hit him instantly.

 

"On the printout, there are four types of villains! If this is a misprint, then UA, the top hero academy in Japan, should be ashamed of this error!" The boy chopped his hand stiffly through the air. Then, he spun around, pointing directly at Izuku.

 

"And you, with the messy hair!"

 

Izuku froze.

 

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

 

The auditorium chuckled. Izuku shrank in his seat, his face burning.

 

“This one is loud,” Vesper growled in Izuku’s mind, a dark, vibrating hum building in Izuku’s chest. “He points at us. It is a challenge. Let me out, Izuku. I will tear his pointing finger off and feed it to him.”

 

No, Vesper, he's just stressed! Stand down! Izuku mentally wrestled with the symbiote, holding his hands up defensively. "I-I'm sorry!" he squeaked out.

 

"Alright, alright, examinee number 7111!" Present Mic intervened. "Thanks for the great message! The fourth faux villain is worth zero points! It's an obstacle! A massive gimmick that will go crazy in narrow spaces! My advice? Just run away from it!"

 

The stiff boy bowed deeply. "Thank you very much! Please excuse the interruption!"

 

Izuku let out a long breath as the spotlight turned off. The Zero Pointer. An obstacle. He made a mental note to avoid it and focus purely on the point-scoring machines.

 

"THAT'S ALL FROM ME!" Present Mic yelled. "NOW, GO OUT THERE AND SHOW ME WHAT YOU'VE GOT! PLUS ULTRA!"

 

Exam Battle Center B was a breathtaking recreation of a modern metropolis. Towering skyscrapers, sprawling intersections, and complex alleyways formed a massive concrete maze.

 

Dozens of examinees stood behind the massive, towering steel gates. Some were stretching, some were hyperventilating. Izuku stood near the back of the pack. He spotted Katsuki Bakugo a few dozen yards away, looking murderously at the gate. He also spotted the nice girl with the pink cheeks, taking deep, calming breaths.

 

Izuku closed his eyes. He reached inward, past his nerves, past his lingering doubts, to the dark, churning ocean of power that slept in his veins.

 

Wake up, Vesper.

 

“I am awake,” the symbiote replied, its voice entirely devoid of humor, completely locked into a predatory focus. “I smell oil. I hear the hum of engines. Prey.”

 

We hold nothing back. Full lethality on the machines. But we do not touch the other students. Understood?

 

“Understood, Host. Let us hunt.”

 

"START!"

 

Present Mic’s voice boomed from the hidden loudspeakers.

 

The crowd of examinees hesitated for a split second, confused by the lack of a countdown.

 

"WHAT ARE YOU WAITING FOR?! THERE ARE NO COUNTDOWNS IN REAL BATTLES! RUN, RUN, RUN!"

 

The gates began to groan open. The examinees surged forward in a massive wave.

 

Izuku didn't run. Running was too slow.

 

As the crowd poured through the opening gap, Izuku bent his knees. Pitch-black liquid erupted from his forearms, shooting out like twin cannons. The dense, metallic tendrils rocketed over the heads of the crowd, latching onto the roofs of two towering buildings on opposite sides of the main street.

 

Before anyone could register what was happening, Izuku violently retracted the tendrils.

 

BOOM.

 

The concrete beneath Izuku’s feet shattered. He was launched over the heads of the sprinting examinees like a bullet fired from a railgun. He flew over the crowd, a blur of green and black, hurtling deep into the mock city.

 

"What the hell was that?!" a student yelled, looking up.

 

Ten blocks deep into the city, away from the other examinees, a 1-Pointer rolled out of an alleyway. Its red optical sensor locked onto the airborne boy. "TARGET ACQUIRED."

 

Izuku didn't even land. While in mid-air, his right arm was entirely engulfed in thick, bubbling black biomass. The metal-infused symbiote rapidly expanded, shifting and hardening until Izuku’s arm from the elbow down was a massive, spiked wrecking ball the size of a small car.

 

"Smash," Izuku whispered.

 

Gravity took him. He plummeted like a meteor.

 

The impact was deafening. Izuku slammed the symbiote-hammer directly down onto the 1-Pointer’s central chassis. The massive robot didn't just break; it completely crumpled, compressed into a flat disk of sparking scrap metal and leaking oil beneath the sheer, overwhelming kinetic force.

 

A cloud of dust and debris exploded outward.

 

One point, Izuku thought, standing up from the crater. The massive hammer liquefied and retracted, leaving his human arm perfectly fine.

 

Before the dust could clear, three 2-Pointers rounded the corner, their machine guns revving up.

 

“More,” Vesper hissed, the pitch-black liquid now seeping over Izuku’s shoulders and chest, forming a sleek, terrifying armor of jagged spikes.

 

The 2-Pointers opened fire. Rubber bullets rained down on Izuku.

 

He didn't dodge. The bullets struck his symbiote armor and flattened, entirely useless against the titanium-infused biomass. Izuku grinned—a feral, confident smile that belonged more to the monster than the boy.

 

He lunged forward. His speed was terrifying. He closed the distance in a single bound. His hands shifted into massive, three-fingered claws. He grabbed the barrel of the first 2-Pointer’s gun, crushing the thick steel like tin foil, before spinning and tearing the robot’s head clean off its shoulders with a sickening screech of tearing metal.

 

Three points.

 

The second robot tried to back away. Izuku shot a thick web of black sludge from his palm, blinding its optical sensors. He vaulted off the decapitated first robot, driving his knee completely through the second robot's chest plate, rupturing its battery core.

 

Five points.

 

The third robot turned to run.

 

“Mine,” Vesper roared.

 

Izuku didn't chase it. Six massive, serrated tendrils erupted from his back. They shot forward like harpoons, piercing the fleeing robot in six different places. With a violent, savage pull, Izuku tore his arms back. The tendrils violently ripped the robot into six separate, mangled pieces.

 

Seven points.

 

Izuku stood amidst the smoking wreckage, panting slightly. The adrenaline was a drug. He had never been allowed to let loose like this. He had never been allowed to unleash the absolute, apex violence that Vesper was built for. It felt... incredible.

 

Keep going, Izuku commanded, a dark thrill running down his spine. We need more.

 

For the next seven minutes, Izuku Midoriya was a natural disaster.

 

He didn't just break robots; he dismantled them with terrifying, artistic precision. He used the buildings to slingshot himself from street to street, diving down on 3-Pointers like a raptor. When he encountered a group of robots, he spun like a top, extending scythe-like blades from his arms that sheared through titanium chassis like hot knives through butter.

 

Other examinees occasionally crossed his path, only to stop and stare in abject horror as the messy-haired boy tore a massive tank-tread robot in half with his bare, symbiote-covered hands.

 

"He's... he's a monster," one boy muttered, backing away slowly as Izuku crushed a robot's optical sensor with his heel.

 

"Leave this sector!" another girl yelled. "He's taking all the points!"

 

Fifty-two points, Izuku calculated, his breathing heavy, sweat dripping down his face despite the symbiote's cooling effects. Sixty-five points. Seventy-one points.

 

He was unstoppable. He was a god of the battlefield.

 

High above the mock city, behind a wall of tinted, reinforced glass, the faculty of UA High School sat in the dark observation room. Hundreds of glowing monitors illuminated their faces, tracking the progress of every student.

 

"We have quite a crop this year," Midnight purred, licking her lips as she watched Katsuki Bakugo completely incinerate a 3-Pointer. "That blonde boy is vicious. Excellent combat instincts."

 

"Indeed," Snipe agreed, tipping his cowboy hat. "But he lacks situational awareness. He's destroying the environment just to get to his targets."

 

Sitting in the front row, an incredibly tall, skeletal man in a yellow pinstripe suit leaned forward, his hands clasped tightly together. Toshinori Yagi's eyes darted frantically across the screens, searching.

 

"What about examinee 7111?" asked a gruff, tired voice from the corner.

 

Pro Hero Eraserhead, Aizawa Shouta, stepped out of the shadows. He looked like a homeless man wrapped in bandages, his eyes narrowed as he stared at a specific monitor.

 

The screen showed Izuku Midoriya. He was currently standing atop a ruined 3-Pointer. As they watched, his arm dissolved into black liquid, reformed into a massive spike, and violently impaled another robot through a brick wall.

 

"Izuku Midoriya," Aizawa read from a glowing tablet, his voice laced with heavy skepticism. "Quirk: Sentient Biomass. The file says it's a mutation. A secondary consciousness living in his bloodstream that can form physical constructs and enhance physical strength."

 

"It's a terrifying power," Ectoplasm muttered, watching Izuku swing between buildings on black tendrils. "Look at the sheer kinetic force he's generating. And the versatility. Slingshots, armor, blades, hammers. He has an answer for every scenario."

 

"Too violent," Aizawa countered flatly. "He's fighting like a wild beast. It's undisciplined. A Quirk like that, especially one with a 'sentient' tag, is a massive liability. If he loses control in the field, he'll cause more casualties than the villains."

 

Toshinori stiffened, gripping the armrests of his chair. He desperately wanted to defend Izuku, to tell them about the boy's pure heart, but he had to maintain his impartiality as a judge.

 

"I find it fascinating!" chirped Nezu, the principal of UA—a creature that was a mix of a mouse, a bear, and a dog. He sat on a high chair, sipping tea. "Yes, the power is brutal, but look closely, Aizawa. Look at his flight path."

 

Aizawa narrowed his eyes, pulling up a secondary map that tracked Izuku's movements.

 

"He is moving at blinding speeds, taking down dozens of targets," Nezu pointed out with a smile. "But notice where he isn't going. He has actively altered his trajectory four times to avoid crossing paths with other examinees engaged in combat. He hasn't stolen a single point from someone who was already fighting. Despite the beast-like appearance, his spatial awareness and consideration for others are immaculate."

 

Toshinori smiled, a wave of profound pride washing over him. That's right. He's not a monster. He's a hero.

 

"We'll see," Aizawa muttered, unimpressed. "Anyone can look good beating up mechanical toys. But true heroics aren't tested by how well you can destroy."

 

Nezu’s eyes gleamed with a mischievous light. "I completely agree, Eraserhead. The true test of a hero is how they react when there is nothing to gain, and everything to lose."

 

The principal reached out a paw. He flipped a red plastic cover up and slammed his hand down on a massive, glowing button.

 

"Let's see how our examinees handle absolute, overwhelming despair."

 

With two minutes left on the clock, Izuku had seventy-eight points. He was standing in the center of a wide intersection, catching his breath. The symbiote armor retracted completely into his skin, leaving him in his human form to save energy.

 

“We have destroyed them all,” Vesper rumbled happily. “We are apex. The meat-bags with the clipboards will surely give us the highest grade.”

 

Yeah, Izuku smiled, wiping soot from his forehead. I think we did enough.

 

Suddenly, the ground beneath his feet violently shuddered.

 

It wasn't a small tremor. It felt like a massive earthquake. The glass in the surrounding buildings shattered, raining down onto the streets.

 

A deafening, mechanical roar echoed from the north side of the city. Izuku turned, his eyes widening in absolute horror.

 

Rising from behind the skyscrapers, eclipsing the sun, was a machine of biblical proportions. It was hundreds of feet tall, heavily armored in thick green plating, with glowing, malevolent red eyes. The sheer size of it defied physics. As it rolled forward on its massive treads, it effortlessly crushed a four-story building to dust.

 

The Zero Pointer.

 

"IT'S A MONSTER!" someone screamed.

 

Panic erupted instantly. The examinees, who had been confidently destroying the smaller robots moments before, broke rank and sprinted in the opposite direction.

 

"Run!" the stiff boy with glasses, Iida, yelled, waving his arms as he sprinted past Izuku. "It's an obstacle! There's no point in fighting it!"

 

Izuku took a step back. His rational mind entirely agreed. The thing was too big. Even with Vesper's titanium-infused strength, fighting a machine that weighed tens of thousands of tons was suicide.

 

“Threat level critical,” Vesper stated, its mental voice entirely devoid of its usual bloodlust. The symbiote was a predator, but it wasn't stupid. “Host, we cannot consume that. It will crush us. Tactical retreat advised.”

 

Izuku turned to run.

 

"Oww! Help!"

 

Izuku froze. The voice was faint, barely audible over the roaring engines of the behemoth, but it cut through Izuku’s soul like a knife.

 

He whipped his head around. Near the base of the Zero Pointer, amidst the rubble of a destroyed building, was the girl with the pink cheeks. A massive slab of concrete had pinned her leg to the ground. She was struggling frantically to push it off, but she was trapped.

 

And the Zero Pointer’s massive foot was descending, aiming directly for her.

 

Time seemed to slow to a crawl. The other examinees were running away. The Pro Heroes weren't stepping in. The girl was going to be crushed.

 

In that fraction of a second, the terrified, anxious boy named Izuku Midoriya vanished.

 

“Host, no!” Vesper screamed in his mind, sensing Izuku’s intent. “We will die!”

 

Vesper, Izuku commanded, his mental voice echoing with an absolute, terrifying authority that made the symbiote tremble. We are going to save her. Give me everything. Every single drop of power you have. Do not hold back.

 

“...Understood.”

 

Izuku sprinted directly toward the colossal machine. He didn't use tendrils to swing. He used pure, unadulterated leg strength. The concrete shattered into a crater as he leaped into the air, flying straight at the falling foot of the Zero Pointer.

 

As he flew, the transformation began. But this was unlike any transformation he had ever undergone.

 

This wasn't armor. This wasn't a weapon construct. This was a complete, biological synthesis of human willpower and alien mass.

 

Pitch-black liquid erupted from every pore in Izuku's body in a torrential geyser. It engulfed him entirely, hardening and expanding exponentially. He grew to a towering ten feet tall. Massive, grotesque layers of muscle piled upon muscle, shifting and writhing beneath the smooth, black, oily skin.

 

But it wasn't just black. Deep within the symbiote, glowing, neon-green veins pulsed with raw, catastrophic energy—the physical manifestation of Izuku’s adrenaline and life force pushing the symbiote past its limits.

 

The Avatar's face formed. Two massive, jagged white eyes that conveyed nothing but pure, unadulterated fury. The jaw unhinged, revealing rows of shark-like teeth and a long, serpentine tongue.

 

The girl looked up, screaming as the shadow of the Zero Pointer’s foot blocked out the sun.

 

Suddenly, a massive, terrifying black blur intercepted the foot.

 

SLAM!

 

The collision generated a shockwave that blew the surrounding rubble into dust. The shockwave knocked the girl flat on her back. The wind pressure blew the other running examinees off their feet a block away.

 

In the observation room, Aizawa dropped his tablet. All Might stood up, his mouth wide open.

 

Suspended in the air, directly above the trapped girl, the massive black demon was holding the entire weight of the Zero Pointer’s foot with its bare hands.

 

The concrete beneath the demon’s feet was vaporized instantly. Izuku sank up to his knees in the street, his terrifying, muscular arms trembling under the weight of millions of pounds.

 

The machine roared, pushing down harder.

 

Inside the beast, Izuku’s human bones creaked. His vision blurred.

 

“WE ARE APEX!” Vesper’s demonic voice roared simultaneously from Izuku’s human mind and the demon’s physical mouth.

 

The green veins across the symbiote’s black body flared blindingly bright. With a roar that shook the heavens, the demon didn't just hold the foot—it pushed up.

 

The sheer, impossible kinetic force threw the Zero Pointer off balance. The massive machine tilted backward, its gears screaming in protest.

 

But Izuku wasn't done.

 

He vaulted onto the top of the suspended foot, sprinting up the massive leg of the robot at blinding speeds. He reached the central chassis in seconds.

 

The demon reared its arm back. The arm expanded, forming a massive, jagged, titanium-laced spike.

 

"SSMMAAASHH!" the demon roared, a grotesque, terrifying imitation of All Might's signature attack.

 

Izuku drove the spike directly into the heavily armored chest of the Zero Pointer. The titanium plating shattered like glass. Izuku ripped his arm outward, tearing the massive metal plates away, exposing the glowing core of the machine.

 

Vesper didn't hesitate. Massive black tendrils erupted from the demon's chest, plunging deep into the robot's circuitry.

 

With a sickening screech of tearing metal, Izuku violently ripped the entire core out of the machine.

 

The red eyes of the Zero Pointer flickered, and then went completely dark.

 

The behemoth fell backward, crashing into the mock city with the force of a nuclear bomb, kicking up a mushroom cloud of dust and debris.

 

Silence descended upon Battle Center B.

 

The dust slowly began to clear. Standing atop the ruined, smoking chest of the colossal machine was the ten-foot-tall black demon. It stood there for a moment, panting heavily, holding the glowing core in its massive claws.

 

Then, the muscles deflated. The jagged teeth receded. The black mass liquefied and rapidly slithered back into the skin of the boy beneath.

 

Izuku Midoriya stood there in his shredded uniform, his chest heaving, entirely exhausted. He looked down. The pink-cheeked girl was staring up at him, her eyes wide with absolute awe and terror.

 

"Times up!" Present Mic's voice echoed across the ruined city.

 

Izuku smiled weakly at the girl. "Are... are you okay?"

 

Before she could answer, Izuku’s eyes rolled back in his head, and he collapsed backward into the rubble, fast asleep. Vesper had burned every single calorie in his body.

 

In the observation room, there was dead silence.

 

Aizawa stared at the screen, his eyes wide, his usual apathy entirely shattered. Nezu was grinning from ear to ear.

 

Toshinori Yagi placed his hands on the glass, a massive, tearful smile stretching across his face.

 

You did it, my boy. You showed them all.
