What if deku was 10 doctor companions before ua exam

 

 

The world of heroes and villains was built on a foundation of absolutes. Fire burns, ice freezes, gravity pulls, and all men are not created equal. Izuku Midoriya learned this final, crushing absolute at the tender age of four, in a sterile room that smelled sharply of rubbing alcohol and cheap lemon disinfectant.

 

The doctor’s office was a mundane place for a world to end. There were brightly colored posters of Pro Heroes on the walls—Endeavor looking stern, Best Jeanist posing with stiff perfection, and of course, All Might, wearing his trademark blinding smile beneath the bold text: YOU CAN BE A HERO TOO! Izuku sat on the edge of the crinkling paper of the examination table, his short legs swinging back and forth in an anxious, hopeful rhythm. Beside him, his mother, Inko, nervously twisted the strap of her purse.

 

The doctor, a stout, bald man with thick goggles resting on his forehead, sighed. It was a heavy, weary sound, the kind of sound an adult makes when they are about to explain something terribly unfair to a child. He tapped a pen against the glowing lightboard where an X-ray of Izuku’s small, fragile foot was displayed.

 

"You should probably give it up," the doctor said.

 

The words didn't register immediately. They hung in the air, suspended like dust motes in the afternoon sun. Izuku’s swinging legs stopped. The All Might action figure in his small, chubby hand suddenly felt very heavy.

 

"Give... give it up?" Inko echoed, her voice trembling. "Is there something wrong? Most of the other kindergarteners have already started showing signs of their Quirks. He’s just a late bloomer, right?"

 

The doctor leaned back in his rolling chair, the leather squeaking in the quiet room. "Excuse me, but you’re fourth generation, right ma’am? May I ask what your Quirks are?"

 

"Yes, of course," Inko said, her hands fluttering defensively. "I can pull small objects to me. And my husband can breathe fire." She demonstrated by extending a hand, pulling a discarded pen across the doctor's desk and into her palm.

 

"Normally, by age four, a child will manifest one of those Quirks, or some combination of the two," the doctor explained, pointing the blunt end of his pen at the X-ray. "In the past, when Quirks first began showing up, research was published noting a correlation between Quirk manifestation and the presence of an extra joint in the pinky toe. It’s an evolutionary redundancy. Humans with Quirks are a more streamlined, evolved species; they lack that joint. But looking at Izuku’s X-ray here... you can see he has two joints. It's rare these days, incredibly rare. But it means his body hasn't taken the evolutionary step."

 

The doctor turned his chair to look directly at the small, green-haired boy. "Izuku is Quirkless. He will never develop a power."

 

The All Might action figure slipped from Izuku’s fingers. It hit the linoleum floor with a hollow, plastic clatter.

 

The rest of the evening passed in a blurred, suffocating haze. Izuku didn't remember the car ride home. He didn't remember the pitying looks of the neighbors in their apartment building. All he remembered was the deafening silence in his own head, drowning out everything else.

 

By evening, it was raining. A torrential, dreary downpour that battered the windows of the Midoriya apartment. Izuku sat in the dark of his bedroom, lit only by the flickering glow of his computer monitor. On the screen, a vintage video played for the hundredth time. It was a disaster recording—a catastrophic fire, rubble everywhere, sirens wailing in the background. And there, emerging from the wreckage with a dozen people draped over his massive shoulders, was All Might.

 

"He's laughing!" the narrator on the video cried out.

 

"It's fine now," the booming, digitized voice of All Might echoed through the small speakers. "Why? Because I am here!"

 

Izuku stared at the screen, tears welling in his massive, emerald eyes. The door creaked open, spilling a sliver of hallway light into the room. Inko stood there, her face pale, her eyes red and puffy.

 

Izuku slowly turned his chair around. His lower lip quivered. He pointed a trembling, chubby finger at the frozen image of his idol.

 

"Mom," Izuku whispered, his voice cracking with the unbearable weight of a broken dream. "He... he saves everyone with a smile. Even if I don't have a Quirk... can I be a hero too?"

 

Inko broke. She rushed across the room, falling to her knees and pulling her son into a desperate, crushing embrace. "I'm sorry, Izuku!" she sobbed into his shoulder, her tears soaking his shirt. "I'm so, so sorry! I'm sorry!"

 

It wasn't the answer he needed. It was an apology. It was pity. It was a confirmation of his complete and utter worthlessness in a society that valued human beings strictly by the biological parlor tricks they could perform.

 

When Inko finally cried herself to sleep on the sofa later that night, Izuku slipped out of her embrace. He felt numb. His chest ached with a hollow, burning sensation. He couldn't stay in the apartment. The walls felt like they were closing in, plastered with the smiling faces of heroes he was no longer allowed to join.

 

He pulled on his bright yellow rain boots and grabbed a dark green hoodie, pulling it over his unruly curls. He unlocked the front door and stepped out into the stormy night.

 

Musutafu was a sprawling metropolis, usually alive with neon lights and the distant sounds of hero fights. Tonight, however, the streets were empty, washed clean by the relentless downpour. Four-year-old Izuku wandered aimlessly, his small boots splashing through deep puddles. He didn't know where he was going. He just knew he had to get away from the pity.

 

He walked for what felt like hours, guided only by the numbness in his heart. Eventually, the pristine sidewalks gave way to cracked asphalt. The towering, shiny skyscrapers were replaced by squat, rusted warehouses and chain-link fences. He had wandered into the industrial district, a place strictly off-limits to children.

 

Lightning flashed, illuminating a massive, rusted sign hanging askew over a set of heavy iron gates: MUNICIPAL SCRAPYARD 4 - CONDEMNED.

 

The gate was slightly ajar, the padlock rusted through and broken. Seeking shelter from the biting cold wind, Izuku slipped through the gap. The scrapyard was a labyrinth of forgotten things. Towers of crushed cars, mountains of stripped copper wire, and hills of discarded household appliances formed rusted metallic canyons. The rain drummed loudly against the metal, a deafening symphony of decay.

 

Izuku huddled beneath the overhang of a crushed city bus, pulling his knees to his chest. He shivered, the cold finally piercing his numbness. He buried his face in his arms and began to cry, letting the tears mingle with the rain. He was defective. He was a relic. He belonged in a scrapyard just like the broken machines around him.

 

Vworp. Vworp. Vworp.

 

Izuku stopped crying. He lifted his head.

 

Beneath the sound of the rain, there was a strange, rhythmic wheezing and groaning noise. It sounded like a massive ancient beast drawing breath, or a great engine fighting against the wind. It was accompanied by a strange displacement of the air, a sudden shift in atmospheric pressure that popped Izuku's ears.

 

He wiped his eyes with a soggy sleeve and peered into the gloom. The sound had come from deeper within the maze of scrap. Curiosity, momentarily overriding his sorrow, drew him to his feet.

 

He navigated the wet, slippery metal corridors until he rounded a massive pile of discarded washing machines. There, nestled in a clearing of twisted rebar and shattered glass, was something entirely out of place.

 

It was a tall, rectangular wooden box, painted a vibrant, rich blue. It had small, frosted windows near the top, and a sign on the front door that read POLICE TELEPHONE FREE FOR USE OF PUBLIC. A small, white lantern sat atop its roof, glowing with a warm, steady light that seemed entirely unaffected by the driving rain.

 

Izuku stared. There were no police boxes like this in Japan. It looked ancient, foreign, and completely pristine, as if it had simply dropped out of the sky.

 

Drawn by an invisible, magnetic pull, the small boy approached the blue box. The air around it felt... different. It hummed, a low, vibrating energy that Izuku could feel in his teeth. It felt alive.

 

He reached out a small, trembling hand. His fingertips brushed the wet wood of the door. It was warm. Warmer than the air, warmer than the rain.

 

Click.

 

The door, which had appeared solid and locked, popped open an inch. A sliver of brilliant, golden light spilled out onto the muddy ground, cutting through the darkness of the scrapyard.

 

Izuku hesitated. Every instinct taught to him by his mother told him to run away, to find a police officer, to not go into strange places. But he was Quirkless. He had nothing left to lose.

 

Pushing with both hands, Izuku opened the door and stepped inside.

 

The breath left his lungs in a sharp gasp.

 

He was no longer in the rain. He was no longer in the scrapyard. He was standing in a massive, cavernous room that defied every law of physics, geometry, and logic he had ever been taught in kindergarten.

 

The walls were lined with glowing round indentations, pulsing with a soft, warm light. The ceiling vaulted high above him, supported by sweeping, coral-like pillars. In the center of the massive room was a sprawling, hexagonal console, bristling with levers, dials, switches, and glowing monitors. A central glass column rose from the console to the ceiling, rising and falling in a steady, rhythmic heartbeat, filled with swirling, luminescent energies.

 

Izuku turned around. Behind him was the wooden door, still open, showing the rainy, dark scrapyard outside. He looked at the vast room, then back at the door.

 

"It's... it's bigger on the inside," Izuku whispered, his eyes wide.

 

"A rudimentary observation, my dear boy, but entirely accurate!"

 

Izuku jumped, spinning around.

 

Standing on the far side of the console, wiping his hands on a greasy rag, was a man. He was unlike anyone Izuku had ever seen. He was tall, with a regal, commanding posture. He had a shock of stark white, bouffant hair that framed a face etched with deep lines of age, wisdom, and an undeniable aristocratic authority. He wore a ruffled white shirt, a dark cravat, and an immaculate, dark blue velvet smoking jacket, completely devoid of a speck of dirt despite the greasy components scattered across the console.

 

The man tossed the rag aside and picked up a pair of strange, magnifying spectacles, peering over them at Izuku.

 

"Now then," the man said, his voice a booming, theatrical baritone that echoed through the massive room. "The temporal stabilizers indicated a localized chronal anomaly, but I certainly wasn't expecting a stowaway. And a rather damp one at that. Good heavens, child, you’re dripping all over the grating!"

 

Izuku froze, terrified. "I-I'm sorry! I didn't mean to—the door was open—I just—"

 

The man sighed, a dramatic, sweeping sound, and waved a hand dismissively. "No, no, no, don't apologize. It's not your fault. The TARDIS has always been entirely too sympathetic to strays. A side effect of the telepathic circuits, I imagine." The man strode around the console, his velvet coat swishing, and looked down at Izuku. "Well? Don't just stand there looking like a startled owl. What's your name?"

 

"M-Midoriya Izuku," he squeaked, bowing deeply out of habit.

 

"Izuku," the man tasted the word, nodding. "Well, Izuku. I am the Doctor."

 

"The... the Doctor?" Izuku asked, looking around. "Is this a hospital? It doesn't look like a hospital."

 

The man barked a laugh, a loud, joyous sound. "A hospital? Good heavens, no! Although I suppose it is a place of healing, in its own way. This is the TARDIS. Time And Relative Dimension In Space. My ship. And currently, my rather frustrating prison, courtesy of the Time Lords." He muttered the last part with a scowl, kicking a metal panel on the base of the console.

 

Izuku didn't understand most of those words. "Are you... a hero?"

 

The Doctor stopped. He looked at the small, shivering boy, his piercing blue eyes softening slightly. "A hero? No. I am a scientist, an explorer, occasionally an exile, and frequently a nuisance to the establishment. But a hero? That implies a level of organized vanity I simply do not possess."

 

The Doctor reached into a pocket of his velvet jacket, pulled out a handkerchief, and tossed it to Izuku. "Dry your head, boy. You'll catch your death. Now, tell me, what is a child of... what, four? Five? What is a child doing wandering around a condemned industrial sector in a torrential downpour at precisely..." The Doctor pulled a silver pocket watch from his waistcoat and flicked it open. "...two-fourteen in the morning?"

 

The question brought the reality of the day crashing back down on Izuku. The awe of the magical room faded, replaced by the crushing weight of his diagnosis. He gripped the handkerchief tightly, his chin trembling.

 

"I... I ran away," Izuku whispered.

 

"I deduced that," the Doctor said gently, leaning against the console. "But why? Did you break a vase? Argue with your parents?"

 

"I'm broken," Izuku sobbed, the tears returning in full force. He wiped furiously at his eyes, frustrated by his own weakness. "I went to the doctor today. The regular doctor. And he... he told me I'm Quirkless. I'm missing a joint in my toe. I'm not evolved. I can never be a hero. I'm just a useless, defective nobody!"

 

The vast room fell silent, save for the gentle hum of the central column. The Doctor stared at Izuku for a long, unreadable moment. His aristocratic features shifted from curiosity to profound, simmering indignation.

 

"Quirkless?" the Doctor repeated, the word rolling off his tongue with intense distaste. "Evolved? Defective? What absolute, unmitigated rubbish!"

 

Izuku flinched, expecting to be yelled at. Instead, the Doctor crouched down, bringing himself to eye level with the small boy. The sheer presence of the man was overwhelming—he smelled of ozone, old paper, and an undeniable electric energy.

 

"Now you listen to me, Izuku Midoriya, and you listen well," the Doctor said, his voice dropping into a stern, commanding octave that demanded absolute attention. "I have traveled across the length and breadth of this universe. I have seen binary star systems ignite, I have walked on the silver shores of the Medusa Cascade, and I have met species that can alter the very fabric of reality with a thought. And do you know what I have never, ever found?"

 

Izuku shook his head slowly.

 

"A biological mutation that substitutes for character," the Doctor stated firmly. He tapped a long, elegant finger against Izuku’s forehead. "This obsession your planet currently has with 'Quirks'—with shooting fire from your hands or lifting heavy objects—it is a parlor trick! It is merely biology! Biology does not make you a hero. A Quirk is nothing more than a tool, like a hammer or a screwdriver."

 

The Doctor stood back up, towering over the boy, his hands clasped behind his back. "Do you think I need a 'Quirk' to save a planet? No! I use my mind! I use intellect, reason, compassion, and courage. To tell a child they are 'defective' because they lack a superfluous biological adaptation is the height of arrogant, provincial stupidity!"

 

Izuku stared, wide-eyed. No one had ever spoken to him like this. No one had ever dismissed Quirks so casually, as if they were nothing more than a neat party trick.

 

"But... All Might..." Izuku stammered. "He's the greatest hero. He's so strong. He punches the villains away."

 

"Punching villains," the Doctor sighed, pinching the bridge of his nose. "How remarkably primitive. Yes, I suppose brute force has its place, usually when all other avenues of intelligent discourse have failed. But true brilliance, Izuku, true heroism, is about out-thinking your opponent. It's about finding the solution that saves lives, not the one that shatters windows."

 

The Doctor turned back to the console, flipping a series of switches. A monitor flickered to life, displaying a map of the scrapyard outside. Blinking red dots were beginning to appear around the perimeter.

 

"And speaking of shattered windows and primitive violence," the Doctor muttered, his tone shifting back to brisk professionalism. "It appears our time for philosophical debate is up. We have a rather pressing issue."

 

Izuku wiped his nose with the back of his hand, sniffing. "What is it?"

 

"While you were busy feeling sorry for yourself, my instruments picked up a localized broadcast signal of extraterrestrial origin," the Doctor explained, his fingers flying across the controls. "Specifically, an activation signal from a Nestene Consciousness."

 

"A what?"

 

"A disembodied alien intelligence with an affinity for plastic," the Doctor said, not looking up. "It creates physical vessels out of synthetic materials. Autons, they're called. Nasty pieces of work. Essentially, living, homicidal shop window mannequins. They use them as scouting parties to prepare a planet for invasion."

 

The Doctor tapped the screen. "It seems a localized cluster of them has been dormant in this scrapyard—likely discarded department store waste. The thunderstorm must have interfered with the atmospheric interference, allowing the activation signal to punch through. They are waking up."

 

Izuku felt a cold spike of genuine terror pierce his chest. Alien invasions? Living mannequins? This wasn't a cartoon. This was real. "What... what do we do? Should we call the heroes?"

 

"By the time your colorful brawlers arrive, the Autons will have dispersed into the city," the Doctor said dismissively. "No, we must deal with this ourselves. Or rather, I must."

 

The Doctor picked up a strange, cylindrical device from the console. It looked like a silver flashlight with a crystal emitter at the top. He pressed a button, and the tip glowed with a bright blue light, emitting a high-pitched, warbling whine.

 

"My Sonic Screwdriver," the Doctor explained, slipping it into his jacket pocket. He then picked up a tangled mess of wires attached to a heavy, black metal box. "And this is a localized polarity reverser. I've tuned it to the exact frequency of the Nestene activation signal. If I can plug this into the main broadcast relay of the Auton scouts, it will create a feedback loop, short-circuiting their synthetic neural nets and putting them right back to sleep."

 

"So you're going to stop them!" Izuku said, a spark of awe in his chest.

 

"That is the plan, yes," the Doctor said, though his expression tightened. He rolled up the left sleeve of his velvet jacket, revealing a thick, white bandage wrapped tightly around his forearm. "Unfortunately, I had a rather unpleasant encounter with a Silurian battle-cruiser earlier this week. My arm is not entirely functional. And the broadcast relay is located inside a narrow, reinforced drainage pipe at the center of the scrap heap. My hands are too large, and I lack the mobility to reach the connection port."

 

The Doctor looked at the black box in his good hand, then slowly lowered his gaze to Izuku.

 

Izuku shrunk back. "N-no. I can't. I'm Quirkless. I'm just a kid. I'll mess it up."

 

"Izuku," the Doctor said softly, his booming voice replaced by a quiet, intense earnestness. He knelt again. "I cannot fit into that pipe. The Autons are marching toward the city perimeter as we speak. If they reach the populated sectors, thousands of people will die. People with Quirks, people without Quirks. They do not discriminate."

 

The Doctor held out the heavy black box. "I need someone small. I need someone brave. I need an assistant."

 

Izuku looked at the box. His hands were shaking. He thought of the doctor's office. He thought of his mother's tears. He thought of All Might, standing in the rubble, saving people.

 

Can I be a hero too?

 

"You said... biology doesn't make you a hero," Izuku whispered, his voice trembling.

 

"I meant every word," the Doctor affirmed. "Courage is not the absence of fear, Izuku. Courage is being absolutely terrified, and doing what needs to be done anyway."

 

Izuku took a deep, shuddering breath. He reached out with both small hands and took the black box. It was heavy, the metal cold against his skin. "What... what do I do?"

 

The Doctor smiled, a wide, brilliant grin that seemed to banish the shadows in the room. "That's the spirit! Come along, young Midoriya. Let's go save your world."

 

 

 

Stepping back out into the scrapyard was like stepping into a nightmare. The rain had intensified, and the thunder was a constant, rolling roar. The Doctor, having grabbed a sleek black cane with a silver, ornate handle from a stand near the door, strode out into the downpour as if he were taking a leisurely stroll through a park. Izuku scrambled to keep up, clutching the heavy device to his chest.

 

"Keep close to me, Izuku, and stay out of sight," the Doctor ordered, his eyes scanning the maze of rusted metal.

 

They moved deeper into the scrapyard, navigating through the towering mountains of junk. The smell of wet rust and rotting rubber was overpowering. Izuku's heart was hammering against his ribs like a trapped bird.

 

Suddenly, a loud, unnatural sound cut through the rain.

 

Clack. Clack. Clack.

 

It was the sound of stiff, unbending plastic striking the wet asphalt.

 

The Doctor halted, holding up a hand. He pulled Izuku behind the rusted husk of an old delivery truck. "Quiet now," he whispered.

 

From the shadows of the adjacent aisle, figures emerged.

 

Izuku clamped a hand over his own mouth to stifle a scream. They were mannequins. Window display dummies. But they were moving. They walked with a stiff, unnatural, jerky gait, their joints snapping and popping with every step. Their faces were entirely blank—smooth, featureless plastic with only slight indentations where eyes and mouths should be. They wore rotting, discarded clothes they must have found in the trash.

 

One of them turned its featureless head toward the truck. The right hand of the mannequin suddenly dropped open, hinging back at the wrist to reveal a hollow tube built into the plastic arm.

 

"Down!" the Doctor roared.

 

He tackled Izuku into the mud just as a blinding flash of red energy erupted from the Auton's wrist-gun. The beam struck the side of the truck where they had been standing a second before, instantly vaporizing a massive hole in the steel and sending molten slag hissing into the rain.

 

"Run!" the Doctor commanded, hauling Izuku to his feet.

 

They sprinted down the aisle, the Autons turning in unison to pursue them. The plastic monsters were slow, but relentless, firing blasts of red energy that shattered the mountains of scrap around them.

 

"The drainage pipe is just ahead!" the Doctor shouted over the noise of the explosions. He pointed his cane toward a massive pile of concrete rubble and crushed cars. At the base, barely visible, was a rusted iron grate covering a dark pipe. "The main relay is inside there! You have to plug the yellow wire into the central port and press the red button!"

 

"What about you?!" Izuku cried out, his little legs burning as he ran.

 

"I shall provide a distraction!" the Doctor declared.

 

They reached the base of the rubble pile. The Autons, five of them in total, rounded the corner, raising their lethal plastic arms.

 

The Doctor spun around to face them, planting his feet firmly in the mud. He raised his cane, pointing it at the advancing killers. "Right then! Let's see how you handle a little Venusian Aikido!"

 

The first Auton fired. The Doctor didn't flinch. With terrifying speed and precision, he sidestepped the energy beam, spun on his heel, and brought his cane crashing down onto the Auton's wrist, shattering the plastic weapon.

 

"Hai!" the Doctor shouted, a sharp, martial cry.

 

He moved like a dancer, entirely defying his apparent age. He ducked under a second blast, used his cane to hook the leg of another Auton, pulling it off balance, and delivered a devastating, open-palm strike to the chest of a third, sending it crashing backward into a pile of washing machines.

 

Izuku watched, mesmerized. The Doctor had no Quirk. He had no armor. He was an old man in a velvet jacket facing down alien killing machines, and he was winning through pure skill, agility, and absolute confidence.

 

"Izuku! The pipe! Now!" the Doctor bellowed, parrying a clumsy strike from an Auton and sweeping its legs out from under it.

 

The spell was broken. Izuku turned to the rusted iron grate. He grabbed the bars with his small hands and pulled. It was rusted shut. He strained, his muscles burning, but it wouldn't budge.

 

Behind him, more Autons were arriving. The Doctor was holding them off, twirling his cane into a blinding blur, but he was surrounded. An energy blast grazed the Doctor's shoulder, singing the velvet and causing him to stagger.

 

"I can't!" Izuku cried, tears streaming down his face. "I can't open it! I'm not strong enough!"

 

The Doctor, grappling with a plastic monstrosity, locked eyes with Izuku over the chaos.

 

"Strength isn't muscles, Izuku!" the Doctor yelled, his face strained with effort. "Strength is leverage! Use your mind! Look around you!"

 

Izuku sniffed, forcing his panic down. Use your mind. Intellect.

 

He looked at the grate. He looked around. Beside him, protruding from the mud, was a long, heavy iron pry bar, discarded by whoever ran the scrapyard.

 

Izuku dropped the black box. He grabbed the pry bar with both hands, dragging it over to the grate. He jammed the flat end beneath the rusted iron lip. He didn't try to pull it with his arms; he remembered what the Doctor said about leverage. He threw his entire, forty-pound body weight onto the opposite end of the bar.

 

With a screech of tearing metal, the rusted hinges snapped. The grate fell away.

 

Izuku grabbed the black device and scrambled into the dark, foul-smelling pipe. It was incredibly narrow, a claustrophobic tunnel of slime and rust. An adult could never have fit. He crawled forward, scraping his knees and elbows, the sounds of the battle raging outside echoing terribly in the confined space.

 

I am here, Izuku thought, his teeth gritted. I am going to save people.

 

Ten feet in, the pipe widened slightly into a small junction box. In the center, glowing with a sickly, pulsing red light, was a cluster of alien technology—smooth, black plastic wired into a makeshift antenna.

 

Izuku crawled forward. His hands were shaking so badly he could barely hold the device. He found the central port, a hexagonal slot on the side of the alien relay. He grabbed the thick yellow wire from the Doctor's box.

 

Outside, the Doctor cried out in pain. Izuku heard the sickening thud of the old man hitting the ground.

 

Panic surged. Izuku jammed the yellow wire into the slot. It clicked into place. He reached for the red button on the box.

 

Nothing happened.

 

He stared at it in horror. Why wasn't it working? He looked at the alien relay. The port was covered in a thick layer of synthetic slime, preventing a clean connection.

 

"No, no, no," Izuku sobbed. He didn't have time to clean it. The Doctor was dying outside.

 

Think! Find a solution!

 

Izuku remembered the Doctor's Sonic Screwdriver. The high-pitched noise. Sound waves. Energy. He needed to force the connection.

 

Izuku didn't have a screwdriver. But he had two joints in his pinky toe. He had a human body, full of static electricity, wearing rubber boots that insulated him.

 

He grabbed the metal end of the yellow wire with his bare hand, wrapped his other hand around the slimy alien port, and pressed his body against the black box, using his own conductivity to bridge the gap. He slammed his forehead down onto the red button.

 

ZAP.

 

A surge of electricity ripped through the black box, through Izuku's small body, and directly into the alien relay. It wasn't a lethal shock, but it felt like being punched in the chest by a ghost. Izuku screamed as the current seized his muscles.

 

The red light on the alien device flashed blindingly bright, then turned a harsh, screeching blue. The feedback loop initiated.

 

Outside, the Autons froze. The mannequin standing over the fallen Doctor, its wrist-gun aimed at his chest, suddenly spasmed violently. Sparks erupted from its plastic joints. With a collective, rattling sigh, all the Autons in the scrapyard collapsed to the ground, reverting to nothing more than lifeless, broken plastic dummies.

 

In the pipe, the alien relay sparked and died. The black box hissed, venting a small puff of smoke.

 

Izuku let go, collapsing onto the wet floor of the pipe, gasping for air. His body ached, his hands were blistered, and he was covered in mud and slime. But he was alive.

 

"Izuku!"

 

The Doctor's voice echoed down the pipe, fraught with worry.

 

A moment later, the blinding light of the Sonic Screwdriver cut through the darkness. Izuku crawled weakly back toward the entrance.

 

When he emerged from the pipe, the Doctor was waiting. The old man looked battered. His cravat was askew, his velvet jacket was muddy and torn, and a thin line of blood trickled down a cut on his forehead. But as he saw Izuku crawl out, his face broke into an expression of sheer, profound relief.

 

The Doctor tossed his cane aside, dropped to his knees in the mud, and pulled the filthy, wet child into a massive, crushing hug.

 

"Brilliant," the Doctor breathed, his voice thick with emotion. "Absolutely, unequivocally brilliant. You did it, my boy. You did it."

 

Izuku clung to the velvet coat, burying his face in the Doctor's shoulder. The tears came again, but this time, they weren't tears of sorrow. They were tears of relief. He had done it. He had helped. He wasn't useless.

 

"I used my mind," Izuku hiccupped. "I used leverage."

 

The Doctor pulled back, his hands resting on Izuku's shoulders, beaming with pride. "You used intellect. You used courage. You saved me, Izuku, and you saved thousands of people in that city who will never even know how close they came to the end."

 

The Doctor stood up, wincing slightly as he put weight on a bruised leg, and offered his hand to the boy. "Come along. Let's get you cleaned up. I believe I have some medical supplies in the TARDIS that will soothe those blisters."

 

 

 

The inside of the TARDIS felt warmer than before, or perhaps Izuku was just no longer dead inside. He sat on a plush, leather chair near the console, wrapped in a massive, fluffy tartan blanket.

 

The Doctor hummed a jaunty tune as he gently applied a cool, glowing blue salve to Izuku's blistered hands. The pain vanished instantly, replaced by a soothing numbness.

 

"Fascinating biology, humans," the Doctor mused, wrapping a crisp white bandage around Izuku's palm. "So fragile on the outside, yet possessing a tensile strength of spirit that routinely defies the laws of probability."

 

Izuku watched the Doctor work. He looked at the vast, impossible ship around him. "Doctor?"

 

"Yes, Izuku?"

 

"Will... will I ever see you again? After tonight?"

 

The Doctor paused. His expression grew melancholy. He capped the jar of salve and looked at the temporal monitors on the console.

 

"I am afraid not, my boy," the Doctor said gently. "The chronal anomaly that brought you here... it is a localized tether. A temporary bridge. The TARDIS is already repairing the rift. In a few moments, the timeline will snap back into place like a rubber band. You will be returned to exactly where you were when you left. And I must remain here, trying to fix the navigation circuits the Time Lords so rudely disabled."

 

Izuku felt a pang of sadness. "So... I have to go back. Back to being Quirkless."

 

The Doctor turned, his blue eyes blazing with that same intense, aristocratic fire. He walked over and knelt before Izuku once more.

 

"Listen to me, Izuku Midoriya. When you return, the world will tell you that you are less. They will look at your toe, or your blood, or your DNA, and they will try to put you in a box. They will tell you that heroism is exclusive to the genetically fortunate."

 

The Doctor pointed a finger at Izuku's chest, right over his heart. "Do not let them. Do not let their narrow, provincial minds dictate your worth. You are brilliant. You are brave. You proved tonight that the most powerful weapon in the universe is a kind heart and an active mind."

 

The Doctor stood back up, adjusting his cuffs. "Now, before you go, stand up."

 

Izuku blinked, slipping off the chair and letting the blanket fall. "Why?"

 

"Because if you are going to be a hero in a world of brutes, you must know how to defend yourself when wit alone fails," the Doctor said briskly. He raised his hands, settling into a strange, fluid fighting stance. "This is Venusian Aikido. It requires no superpowers, only an understanding of momentum, anatomy, and balance. I only have time to show you the first stance, but it is a foundation. Watch closely."

 

For the next ten minutes, the TARDIS became a dojo. The ancient, brilliant Time Lord patiently guided the four-year-old boy through the precise footwork and hand positions of the alien martial art. He taught Izuku how to use an opponent's weight against them, how to strike nerve clusters, and most importantly, how to maintain a calm center in the face of aggression.

 

"Always keep your center of gravity low," the Doctor instructed, adjusting Izuku's small arms. "Let the aggressor bring the fight to you, and redirect it. Like water flowing around a stone. Excellent. Now, shout with it. Hai!"

 

"Hai!" Izuku yelled, his voice echoing in the console room, mimicking the precise strike.

 

The Doctor beamed. "Splendid! Practice that every day. Build your body to support your mind, and there won't be a villain on this planet that can stand in your way."

 

Suddenly, the TARDIS let out a deep, echoing groan. The central column flashed rapidly.

 

The Doctor sighed, looking at the monitors. "Ah. It seems our time is up. The tether is snapping back."

 

Izuku felt a strange, tingling sensation starting in his toes and moving up his legs. He looked down and saw his body begin to shimmer, turning slightly translucent. Panic flared for a second, but then he looked up at the Doctor.

 

The old man was smiling warmly, a look of immense pride on his lined face.

 

"Goodbye, Izuku Midoriya," the Doctor said, offering a slight, elegant bow. "It has been an absolute privilege. Remember what I taught you. Never be cruel, never be cowardly. And above all else, never give up."

 

"Goodbye, Doctor," Izuku whispered, tears blurring his vision. "Thank you. Thank you for believing in me."

 

The light engulfed him. The humming of the TARDIS faded into the roaring sound of rain.

 

Izuku blinked.

 

He was standing beneath the crushed city bus in the scrapyard. The rusted metal was cold against his back. He looked around wildly. The blue box was gone. The rubble was untouched. The Autons were nowhere to be seen. It was as if none of it had ever happened.

 

But then, he looked down at his hands.

 

Beneath the dirt and mud, wrapped securely around his blistered palms, were crisp, perfectly clean white bandages.

 

He wasn't crazy. It was real.

 

Izuku stepped out from under the bus. The rain washed over his face, mixing with his tears, but he wasn't crying from sorrow anymore. He looked up at the stormy sky of Musutafu. The city was still filled with heroes who could breathe fire, fly, and smash buildings. He still had a missing joint in his toe.

 

But he was no longer defective. He was the boy who saved the Doctor.

 

He took a deep breath, raised his small, bandaged hands, and settled into the precise, fluid stance of Venusian Aikido.

 

"Hai!"

 

The shout was small, lost in the thunder, but it was fierce. It was a promise.

 

Izuku Midoriya turned his back on the scrapyard and began the long walk home. He had a lot of work to do. He needed to start studying. He needed to start training. He didn't have a Quirk, but he had a mind, he had courage, and he had a secret weapon that no one in this world could ever comprehend.

 

He was going to be a hero. And he was going to be absolutely brilliant.

 

 

The playground was a battlefield, though only one side was armed.

 

At six years old, the hierarchy of the world had solidified for Izuku Midoriya. Two years had passed since the torrential night in the scrapyard, two years since his life was cleaved into 'Before the Doctor' and 'After the Doctor'. To the rest of the world, Izuku was the neighborhood tragedy, the Quirkless boy with big, sad eyes who was destined for a life of mediocrity.

 

But Izuku knew a secret. He knew that the universe was impossibly vast, older than comprehension, and filled with wonders that made shooting fire from one’s hands look like a cheap parlor trick.

 

He had kept his promise. Every morning, before his mother woke, Izuku stood in the cramped space between his bed and his All Might poster, lowering his center of gravity and practicing the precise, flowing stances of Venusian Aikido. He practiced the breathing, the footwork, the redirection of momentum. He was still small, his muscles barely developed, but he was building the foundation. The Third Doctor had told him to use his mind, to build his body to support his intellect.

 

Unfortunately, intellect was entirely lost on Katsuki Bakugo.

 

"Hey, Deku!"

 

The voice, shrill with childish arrogance, cut through the humid afternoon air of the local park. Izuku, who had been sitting under the shade of a large oak tree meticulously sketching the structural weaknesses of the park's jungle gym in a frayed spiral notebook, froze.

 

He looked up. Katsuki Bakugo stood a few feet away, flanked by two other boys. Katsuki’s hands were stuffed into the pockets of his shorts, his ash-blond hair spiking up in every direction. He had a smug, predatory grin plastered across his face.

 

Katsuki’s Quirk had manifested a year ago. Explosion. He could secrete nitroglycerin-like sweat from his palms and ignite it at will. It was loud, flashy, and utterly devastating. The teachers praised him. The neighborhood adults fawned over him. He was a hero in the making, the undeniable king of the sandbox. And like all kings, he required a peasant to step on to elevate himself.

 

"Whatcha writing, Deku?" Katsuki demanded, taking a step forward. Tiny, warning pops of caramel-scented explosions sparked off his palms. "More of your stupid hero notes? You still haven't figured it out, have you? You can't be a hero. You're just a pebble."

 

Izuku closed his notebook, his knuckles white. Before the scrapyard, he would have cowered. He would have cried. But now, he looked at Katsuki and saw exactly what the boy was: predictable. Katsuki operated on a very simple, binary system. He intimidated, and his victim submitted. It was an equation of fear.

 

Like water flowing around a stone, the Third Doctor’s voice echoed in Izuku’s memory.

 

"I'm just taking notes, Kacchan," Izuku said evenly, keeping his voice carefully neutral. He slowly got to his feet, slipping the notebook into his yellow backpack.

 

Katsuki's eyes narrowed. He hated that tone. He hated that Izuku didn't flinch anymore. "You think you're better than me? You think you can look down on me, you Quirkless nobody?!"

 

Katsuki lunged. His right hand came forward in a sweeping arc, a burst of heat and concussive force blooming from his palm, aimed right at Izuku’s chest.

 

Izuku didn't think; he reacted. Muscle memory, drilled into him through two years of solitary morning routines, took over. He dropped his center of gravity, pivoting on his heel. He didn't block—blocking an explosion was mathematically foolish. Instead, he slipped perfectly to the outside of Katsuki's arc.

 

Katsuki stumbled past him, his explosion detonating harmlessly against the trunk of the oak tree, scorching the bark.

 

For a second, there was total silence. The two cronies stared in disbelief. Katsuki whipped around, his crimson eyes wide with absolute fury.

 

"Did you just dodge me?" Katsuki snarled, his voice dropping into a dangerous, feral register. "You little freak! I'll kill you!"

 

Izuku realized then that he had miscalculated. Venusian Aikido was meant for self-defense, but Katsuki was not a rational opponent who would stand down after a failed strike. He was an apex predator who had just been embarrassed in front of his pack.

 

More explosions cracked in Katsuki’s hands, larger this time, smoke curling into the air.

 

Izuku turned and bolted.

 

He ran faster than his short legs had ever carried him, darting away from the playground and into the denser, wooded section of the municipal park. He heard Katsuki roaring behind him, the terrifying CRACK-BOOM of explosions propelling the blond boy forward.

 

Branches whipped at Izuku’s face as he scrambled over gnarled roots and pushed through overgrown bushes. He needed to find a place to hide, a place where Katsuki’s linear, explosive attacks would be useless. His breath came in ragged gasps. Fear, cold and primal, gripped his chest. Despite the martial arts, despite the knowledge of the universe, he was still just a six-year-old boy running from a localized human bomb.

 

He broke through a thicket of thorns, stumbling into a secluded clearing completely enclosed by ancient, towering pines. It was a dead end.

 

Izuku spun around, backing up against a massive rock outcropping. He could hear Katsuki crashing through the brush, drawing closer.

 

I'm trapped, Izuku thought, panic rising. He's going to corner me.

 

And then, the wind changed.

 

The leaves in the clearing ceased their rustling. The distant sounds of traffic and shouting children faded away, swallowed by a profound, heavy silence. The air pressure dropped sharply, making Izuku’s ears pop. The hairs on his arms stood on end, buzzing with a sudden, localized static charge.

 

Wait. I know this feeling.

 

From the center of the clearing, a sound emerged. It was a wheezing, groaning, rhythmic labor, like the grinding of ancient tectonic plates or the breathing of a mechanical leviathan.

 

Vworp. Vworp. Vworp.

 

A gust of wind swept through the clearing, swirling dust and pine needles into a miniature cyclone. Right in the epicenter of the phenomenon, a shape began to materialize, flickering in and out of existence like a mirage before solidifying with a heavy, wooden thud.

 

It was the blue box. The TARDIS.

 

Izuku’s jaw dropped. The fear of Katsuki vanished entirely, vaporized by a tidal wave of awe. The TARDIS had returned. The Doctor had come back.

 

Without a second thought, Izuku sprinted forward and pushed against the wooden door. It swung open effortlessly, offering no resistance. He tumbled inside, slamming the door shut behind him just as Katsuki burst into the clearing.

 

Izuku stood panting, his back pressed against the warm wood of the door. The immediate contrast from the humid, sun-dappled park to the immense, humming cathedral of the TARDIS console room was staggering. It was exactly as he remembered it. The coral pillars stretching up to the vaulted ceiling, the glowing roundels lining the walls, and the massive, hexagonal console dominating the center, the glass time rotor rising and falling with its rhythmic, soothing heartbeat.

 

"Doctor!" Izuku cried out, his voice echoing in the cavernous space. "Doctor, you came back!"

 

He ran around the console, expecting to see the tall, white-haired man in the immaculate velvet jacket. He expected a stern, aristocratic greeting.

 

Instead, a head popped up from beneath a panel on the floorboards.

 

"Ah! Hello there!"

 

Izuku skidded to a halt. The man looking at him was most certainly not the Third Doctor.

 

This man had a mop of impossibly thick, curly brown hair that seemed to possess a chaotic life of its own. He had wide, incredibly expressive eyes that currently shone with a manic, delighted energy. Most remarkably, he was dressed in a bohemian explosion of conflicting textures. He wore a floppy brown fedora, a long, tweed frock coat over a mismatched waistcoat, and—most conspicuously—a knitted scarf of staggering, ridiculous proportions. It was striped in shades of mustard yellow, burgundy, brown, and green, wound around his neck several times, with the ends still trailing all the way down to the metal floor grating.

 

The man scrambled up from the floor, moving with a gangly, unpredictable energy. He brushed dust off his trousers, adjusted his floppy hat, and flashed a wide, toothy grin that stretched from ear to ear.

 

"Well, well, well, what have we here?" the man boomed, his voice a rich, rolling baritone that lacked the aristocratic edge of the Third Doctor but carried twice the theatrical flair. "A localized chronal tether! How utterly fascinating! I thought I felt a bump in the time vortex. It’s like hitting a temporal pothole, really. Shakes the fillings right out of your teeth! Now, who might you be, my diminutive intruder?"

 

Izuku stared, completely bewildered. "I... I'm Izuku. Izuku Midoriya. Where... where is the Doctor?"

 

The man's eyes went even wider. He pointed a long, slightly grubby finger at his own chest. "Where is the Doctor? What a ridiculous question. I am the Doctor!"

 

"No, you're not!" Izuku protested, taking a step back. "The Doctor has white hair! And he wears a velvet jacket! And he knows Venusian Aikido! You... you're wearing a giant scarf!"

 

The man looked down at his scarf, picking up one end and admiring it. "Beautiful, isn't it? Madame Nostradamus knitted it for me. A remarkably talented woman, though terrible at predicting the weather. But as to your point..."

 

The man—the Doctor—stepped forward, leaning down so his face was level with Izuku's. The manic energy receded for a split second, replaced by a deep, ancient intellect that Izuku recognized instantly. It was the exact same feeling he had when he looked into the Third Doctor's eyes. It was a gaze that had seen stars burn out and galaxies collide.

 

"You see, Izuku Midoriya," the Doctor said gently, tapping his own temple, "Time Lords are a remarkably resilient bunch. When our bodies wear out, or take a little too much damage... say, from radiation, or a nasty fall, or just general wear and tear... we don't die. We change. We regenerate. Every cell in our body undergoes a complete biological overhaul. It’s a bit like a caterpillar turning into a butterfly. Only with far more shouting and occasional amnesia."

 

Izuku’s eyes widened. "You... changed your body? Like a Quirk?"

 

"A Quirk?" The Doctor scoffed, waving his hand dismissively and standing back up. "Please. That word again. No, it’s not a parlor trick, my boy, it’s a biological imperative! New body, new teeth, new hair, new tastes! In fact..."

 

The Doctor reached deep into the pocket of his tweed coat and pulled out a crinkling white paper bag. He held it out toward Izuku.

 

"Would you care for a jelly baby?"

 

Izuku blinked. He looked at the paper bag, then up at the towering, eccentric man. Hesitantly, he reached into the bag and pulled out a small, red, sugar-dusted candy. He popped it into his mouth. It tasted like strawberries.

 

"See? Excellent choice!" The Doctor beamed, popping a green one into his own mouth. "Now, tell me, why did you come charging into my TARDIS looking like you were being chased by a pack of rabid Sontarans?"

 

The mention of the chase brought reality crashing back. "Kacchan," Izuku whispered. "There's a boy. He's bullying me. He has an explosion Quirk, and I dodged his attack, and he got really mad."

 

"Ah. A bully," the Doctor said, his smile fading into a look of profound distaste. "How terribly pedestrian. Bullies are all the same, Izuku, across the entire cosmos. Cybermen, Daleks, Sontarans, schoolyard tyrants with superiority complexes... they all operate on the exact same tedious frequency. They believe that might makes right, and they have absolutely zero imagination."

 

Before Izuku could process that, a side door leading deeper into the TARDIS hissed open. A woman stepped out. She was young, with dark, shoulder-length hair, wearing a striped top and incredibly flared trousers that screamed of the 1970s. She was holding two mugs of steaming tea.

 

"Doctor, the kettle was acting up again, I think the temporal stabilizers are interfering with the—" She stopped, noticing Izuku. Her eyes softened instantly. "Oh! Hello. Who's this?"

 

"Sarah Jane Smith, meet Izuku Midoriya," the Doctor announced with a grand flourish of his scarf. "Izuku, this is my best friend, Sarah Jane. A journalist of the highest caliber and a purveyor of excellent tea."

 

"Hi," Izuku squeaked, bowing politely.

 

Sarah Jane set the mugs down on the console and knelt beside Izuku, offering a warm, genuine smile. "Nice to meet you, Izuku. You look a bit shaken up. Are you alright?"

 

No one besides his mother ever asked him that. Izuku felt a lump form in his throat, but he swallowed it down and nodded. "I'm okay. The Doctor gave me a jelly baby."

 

"He does that," Sarah Jane chuckled, throwing a fond exasperated look at the Time Lord. "It’s his solution to most of the universe's problems."

 

"And a highly effective one!" The Doctor protested, bounding over to the console and pulling a series of levers. "Now then! Since we have a guest, and since he is currently hiding from a spectacularly uncreative bully, I say we go on a field trip. Izuku! How would you like to see a world where imagination is the fundamental law of physics?"

 

Izuku’s eyes widened. "We're going to another planet?"

 

"Not just another planet! We are going to Gargantua Prime!" The Doctor slammed his hand down on a large, red button. "Specifically, the Labyrinth of the Laughing King! Hold onto your hats! Or, in your case, your hair!"

 

The central column of the console roared to life, plunging up and down. The entire room lurched violently. Izuku yelped, grabbing onto the railing of the console to keep his footing. The TARDIS groaned, a beautiful, terrifying sound of ripping through the fabric of space and time.

 

The flight lasted only a minute, but to Izuku, it felt like an eternity of exhilarating turbulence. With a final, resonant THUD, the ship settled. The humming died down to a gentle purr.

 

The Doctor practically skipped to the door. "Come along, come along! No time to dawdle! The universe is waiting!"

 

He threw the doors wide open.

 

Izuku stepped out, and his breath was instantly stolen away.

 

They were not in a forest, or a city, or a scrapyard. They were standing on a plateau overlooking a landscape that defied everything Izuku thought he knew about reality.

 

The sky above was not blue, but a swirling, vibrant canvas of magenta and deep violet, dotted with three tiny, silver moons that seemed to dance in orbit. The ground beneath his boots wasn't dirt, but a soft, spongy moss the color of crushed turquoise. But the most striking feature was the environment immediately surrounding them.

 

They had landed at the entrance of an impossibly massive maze. The walls of the labyrinth were made of towering, crystalline hedges that shimmered with a thousand different hues. Strange, bioluminescent flowers bloomed on the crystal branches, humming a low, harmonious melody that Izuku could feel in his teeth.

 

"Incredible," Sarah Jane breathed, stepping up beside him. "Doctor, what is this place?"

 

"Gargantua Prime!" the Doctor announced, spreading his arms wide as his scarf caught the alien breeze. "Home to an ancient race of beings who decided that reality was far too sensible. So, they built this. The Laughing King's Labyrinth. It is a playground of the mind, designed to test the intellect, wit, and humor of anyone who enters."

 

Izuku walked up to one of the crystalline walls, mesmerized. He reached out a hand. As his fingers brushed the crystal, the wall giggled.

 

Izuku jumped back. "It... it laughed!"

 

"Of course it did!" the Doctor beamed. "It's ticklish! Everything here is reactive. The entire maze is a giant, sentient puzzle box."

 

"Why did we come here?" Izuku asked, looking at the towering bohemian.

 

"Because, my boy, you need a lesson in lateral thinking," the Doctor said, his tone turning surprisingly serious despite his manic grin. "You are small. You lack physical power in a universe that unfortunately prizes it. If you try to fight your bully—or any monster, for that matter—on their terms, you will lose. You must fight them on your terms. You must break their script. You must be entirely, bafflingly unpredictable. And there is nowhere better to learn unpredictability than here."

 

The Doctor turned and confidently strode into the entrance of the labyrinth. "Come along! Let's see what the Laughing King has cooked up for us today!"

 

Sarah Jane took Izuku’s hand. "Stay close. With him, a simple walk can turn into a marathon very quickly."

 

They followed the Doctor into the maze. The corridors of crystalline hedge twisted and turned, bathing them in shifting, kaleidoscopic light. The air smelled like ozone and cotton candy. For a while, it was a peaceful, if bizarre, stroll. The Doctor rambled endlessly about the architectural merits of impossible geometry, completely unbothered by the fact that they were hopelessly lost within five minutes.

 

Then, they rounded a sharp corner and came to an abrupt halt.

 

The path forward was gone. Instead, there was a massive, yawning chasm that stretched down into darkness. On the other side, about thirty feet away, the path continued. There was no bridge. There were no ropes.

 

"Well, that's a bother," the Doctor muttered, scratching his chin.

 

"How do we get across?" Sarah Jane asked, peering nervously over the edge. "Is there a hidden bridge? An anti-gravity field?"

 

The Doctor reached into his pocket and pulled out his Sonic Screwdriver—a slightly different model than the one Izuku remembered, sleeker and emitting a lower-pitched hum. He scanned the chasm.

 

"No forcefields," the Doctor deduced. "No invisible bridges. Just a very long, very fatal drop."

 

Izuku analyzed the situation, his mind racing. He looked at the walls. He looked at the ceiling. "Maybe there's a switch? Or a puzzle we have to solve?"

 

"Ah! Good instinct, Izuku!" the Doctor pointed at him. "You're looking for the conventional rules of a trap. But remember where we are. This is a place of absurdity."

 

The Doctor walked to the very edge of the chasm. He took a deep breath, puffed out his chest, and then, at the top of his lungs, he began to sing a completely ridiculous, off-key sea shanty.

 

"Oh, what do you do with a drunken sailor, what do you do with a drunken sailor..."

 

"Doctor, what on earth are you doing?!" Sarah Jane hissed, looking around as if the alien authorities might arrest them for disturbing the peace.

 

"Early in the morning!" The Doctor finished the verse with a bellowing crescendo.

 

Suddenly, from the empty air above the chasm, a solid, glowing pathway made entirely of frozen musical notes materialized. It formed a perfect, curving bridge to the other side.

 

Izuku's jaw hit the floor. "You... you sang a bridge into existence?"

 

"Solidified acoustic resonance!" the Doctor declared, stepping onto the glowing music notes. They chimed pleasantly beneath his boots. "The chasm responds to the sheer absurdity of vocal expression. It expected fear. It expected hesitation. I gave it a sea shanty! Come along!"

 

Sarah Jane sighed, shaking her head, and carefully led Izuku across the chiming bridge.

 

He broke the script, Izuku thought, a profound realization taking root in his mind. The trap had rules. He ignored them and made his own.

 

They continued deeper into the maze. The traps became increasingly bizarre. They encountered a door that would only open if you told it a terrible pun (the Doctor obliged with a joke about Daleks and stairs that made Sarah Jane groan aloud). They navigated a room where gravity shifted every ten seconds based on the color of the floor tiles you stepped on.

 

Izuku was learning. He stopped looking at the obstacles as physical barriers and started looking at them as psychological tests. He began to see the logic within the illogical.

 

However, the labyrinth was not entirely benign.

 

After an hour of wandering, they entered a massive, circular courtyard. The crystalline walls here were darker, pulsing with a deep crimson light. In the center of the courtyard sat a pedestal, upon which rested a glowing, golden orb.

 

"Ah! The core of the sector," the Doctor said, his eyes lighting up. "Fascinating energy signature. I just want to take a little reading..."

 

He stepped forward.

 

"Doctor, wait!" Sarah Jane cautioned. "It feels different here."

 

She was right. The humming of the flowers had stopped. The air felt heavy, oppressive.

 

Before the Doctor could reach the pedestal, the ground trembled. From the crimson walls of the courtyard, an entity emerged. It didn't step out; it peeled itself off the surface of the crystal like a shadow detaching from a wall.

 

It was a terrifying creature. It looked like a towering, jagged amalgamation of broken glass and living darkness. It had no face, only a gaping, jagged maw filled with translucent fangs. It radiated a cold, paralyzing aura of pure dread.

 

Izuku stumbled backward, a gasp escaping his lips. It was the same primal fear he felt when Katsuki cornered him, magnified a hundredfold.

 

The creature whipped its head toward Izuku and Sarah Jane. It sensed their fear. It fed on it. With a bone-chilling screech that sounded like grinding metal, it lunged toward them.

 

"Run!" the Doctor shouted, drawing his Sonic Screwdriver.

 

Sarah Jane grabbed Izuku’s hand and pulled him toward the exit of the courtyard. But the creature was incredibly fast. It swept a massive, jagged arm out, striking the ground in front of them. The crystal floor shattered, creating a localized shockwave that threw Sarah Jane and Izuku into the air.

 

They crashed hard onto the ground. Izuku rolled, scraping his elbows, but quickly pushed himself up. He looked over. Sarah Jane was trapped. The impact had triggered a defense mechanism in the floor; a cage of thick, glowing energy bands had erupted around her, pinning her to the ground.

 

"Doctor!" Sarah Jane yelled, struggling against the energy bands. "I'm stuck!"

 

The glass creature turned its attention entirely to her. It loomed over the energy cage, its jagged maw opening wide, preparing to feed on her terror.

 

"Hey! You overgrown chandelier!" the Doctor roared. He bounded across the courtyard, his scarf flying wildly. He aimed the Sonic Screwdriver at the creature, emitting a high-pitched pulse.

 

The creature shrieked, annoyed but unhurt. It swatted at the Doctor with astonishing speed. The Doctor tried to duck, but the creature's massive hand clipped his shoulder, sending the Time Lord tumbling across the hard crystal floor. He hit the wall with a sickening thud and lay still, his floppy hat knocked askew.

 

"Doctor!" Izuku screamed.

 

Izuku was alone. The Doctor was down. Sarah Jane was trapped. The monster was rearing up, ready to strike the helpless journalist.

 

Panic threatened to drown Izuku completely. His instincts screamed at him to hide, to freeze, to cry. He was six years old. He was Quirkless. He couldn't fight a monster made of glass and nightmares.

 

If you try to fight them on their terms, you will lose.

 

The Doctor's words echoed in his mind.

 

You must fight them on your terms. You must break their script.

 

What was the script? The monster was a predator. It fed on fear. It expected its victims to cower, to scream, to run. If Izuku ran, Sarah Jane would die. If he fought it, he would die.

 

Be bafflingly unpredictable.

 

Izuku stood up. He stopped trembling. He took a deep breath, lowering his center of gravity into the first stance of Venusian Aikido, not to strike, but to ground himself.

 

He didn't run away. He ran directly toward the terrifying glass monster.

 

"Hey!" Izuku yelled, his high-pitched, childish voice echoing in the courtyard.

 

The creature paused. It turned its featureless head toward the tiny boy charging at it. It seemed momentarily confused. Prey did not charge.

 

Izuku stopped ten feet away from the monster. He looked up at its towering, jagged form. He forced every ounce of fear down into the pit of his stomach. He remembered the Doctor singing the sea shanty. He remembered the Doctor offering him candy while running from a killer.

 

Izuku plastered the widest, most ridiculous grin he could manage onto his face.

 

He reached into the pocket of his shorts. He pulled out his hand, curled into a fist, and extended it toward the terrifying monstrosity.

 

"Would you care for a jelly baby?" Izuku asked loudly, maintaining aggressive, unblinking eye contact with the creature's faceless visage.

 

The monster froze completely.

 

It was a being composed of predatory instinct and fear-consumption. It had no psychological framework to process a six-year-old boy offering it candy with a manic smile. The creature's internal logic shattered. Its jagged form vibrated, emitting a confused, high-pitched whining sound, like a dial-up modem failing to connect.

 

It's working, Izuku thought, his heart hammering against his ribs. I broke its script.

 

But Izuku didn't stop there. He knew he had to keep the creature off balance. He dropped his hand, put his thumbs in his ears, wiggled his fingers, and crossed his eyes, sticking his tongue out in the most absurd, ridiculous face he could make.

 

Then, he began to dance. A terrible, rhythmic, stomping dance, singing the only song that came to his mind—the stupid, catchy jingle from an All Might cereal commercial.

 

"Crunchy, punchy, hero power! Start your day within the hour!"

 

The creature recoiled. It physically backed away from the boy. It wasn't just confused now; it was repulsed. There was no fear to feed on. There was only pure, weapons-grade absurdity. The creature's form began to destabilize, the jagged glass edges melting into a soft, harmless mist as its energy source was completely denied.

 

"Be a hero, big and strong! With this cereal you can't go wrong!" Izuku finished with a dramatic pose, pointing finger-guns at the dissolving beast.

 

With a final, pathetic hiss, the creature melted completely into the crystal floor, vanishing as if it had never been there.

 

Simultaneously, the energy cage holding Sarah Jane dissipated.

 

Izuku dropped his arms, panting heavily. The absurd smile vanished, replaced by profound relief. His knees gave out, and he collapsed onto his rear end.

 

"Izuku!" Sarah Jane scrambled to her feet and rushed over, pulling the boy into a tight hug. "Are you alright? That was... that was incredible!"

 

"I broke its script," Izuku mumbled into her shoulder.

 

"Indeed you did! And magnificently so!"

 

The booming voice came from across the courtyard. The Doctor was back on his feet, rubbing his head and adjusting his fedora. He strode over, his long scarf trailing behind him, a look of immense pride on his face.

 

"A masterclass in lateral thinking!" the Doctor declared, kneeling beside them. "You denied it its primary food source—fear—and overloaded its cognitive processors with sheer, unadulterated nonsense! Brilliant! Simply brilliant! I couldn't have done it better myself."

 

The Doctor reached into his coat pocket and pulled out the white paper bag. He held it out. "I believe you have earned a real jelly baby, my boy."

 

Izuku took one. A green one. He popped it into his mouth. It tasted like lime and victory.

 

"You see, Izuku," the Doctor said gently, his manic energy settling into deep, ancient warmth. "The universe is full of monsters. Some are made of glass, some are made of metal, and some are just angry little boys with explosions in their hands. They all want the same thing. They want you to be afraid of them. They want you to play by their rules."

 

The Doctor tapped Izuku on the nose. "Never play by their rules. When they expect you to cry, laugh. When they expect you to run, stand still and offer them candy. You strip them of their power when you refuse to be their victim."

 

Izuku looked down at his hands. He wasn't Quirkless Izuku in this moment. He was the boy who outsmarted a nightmare.

 

"I understand," Izuku said, looking up with fierce determination in his emerald eyes. "I have to be unpredictable."

 

"Exactly!" The Doctor stood up, clapping his hands together. "Now! I believe we have successfully raided the Laughing King's pantry of life lessons. What say we head back to the TARDIS before the floor decides to turn into a giant trampoline?"

 

 

 

The return trip in the TARDIS was a blur of euphoric energy. The Doctor let Izuku pull a few levers on the console (under strict supervision), explaining the mechanics of temporal navigation in terms that made absolutely no sense but sounded wonderfully exciting.

 

Before Izuku knew it, the familiar, rhythmic grinding sound signaled their arrival.

 

"Right on time, and right on the money," the Doctor announced, checking a monitor. "Earth. Japan. Musutafu Municipal Park. Precisely three seconds after you stepped through the door."

 

Izuku felt that familiar, heavy sadness settling into his chest. It was time to go back. Back to being Quirkless. Back to Katsuki. But this time, the sadness wasn't accompanied by despair.

 

Sarah Jane gave him one last hug. "You're a brave kid, Izuku. Don't let anyone tell you otherwise."

 

"Thank you, Sarah Jane," Izuku said politely.

 

He walked over to the TARDIS doors. The Doctor was leaning against the frame, his impossibly long scarf wrapped securely around his neck, his hands in his pockets.

 

"Well, Izuku," the Doctor said, offering a soft, melancholy smile that didn't quite reach his wide eyes. "It seems the temporal tether is pulling you back to your reality. I suspect my predecessor already gave you the lecture about not letting your biology define you."

 

"He did," Izuku nodded.

 

"Good man. A bit stuffy, far too fond of velvet, but a good man." The Doctor crouched down, placing a hand on Izuku's shoulder. "Remember Gargantua Prime, Izuku. Remember the Laughing King. A hero doesn't always have to scowl and punch. Sometimes, a hero smiles in the face of the darkness, simply to show the darkness that it cannot win."

 

The Doctor reached out and ruffled Izuku’s curly green hair.

 

"Be brilliant, Izuku Midoriya. And never take the universe too seriously."

 

The familiar tingling sensation started in Izuku's toes. The world around him began to shimmer.

 

"Goodbye, Doctor," Izuku said.

 

"Goodbye, my boy. Oh, and one last thing!" The Doctor quickly reached into his pocket and shoved something into Izuku's hand just as the light consumed him.

 

Izuku blinked.

 

He was back in the clearing in the park. The pine trees towered above him. The hum of the TARDIS was gone, replaced by the sound of breaking branches.

 

"DEKU!"

 

Katsuki Bakugo burst into the clearing, his hands popping with small, threatening explosions. His face was twisted into a mask of pure, childish rage. He had tracked Izuku down. There was nowhere left to run. The rock wall was at Izuku's back.

 

"Think you can run away from me?!" Katsuki snarled, stepping closer, raising his glowing palms. "You're nothing! You're Quirkless garbage! I'm going to show you exactly where you belong!"

 

Izuku stood frozen for a fraction of a second. The instinct to cower, built over years of bullying, screamed at him to drop to his knees and cover his head.

 

But Izuku looked at Katsuki. Really looked at him.

 

He didn't see a powerful hero-in-training. He saw a predictable, narrow-minded bully trapped in a rigid logic loop. Katsuki expected fear. Katsuki needed fear to fuel his superiority.

 

Izuku took a breath. He felt the object the Doctor had shoved into his hand.

 

Izuku relaxed his shoulders. He stood up straight. He looked the terrifying, explosive boy right in the eyes, and he smiled.

 

It wasn't a nervous smile. It wasn't a timid smile. It was a wide, beaming, completely unbothered grin, reminiscent of a madman in a bohemian scarf.

 

Katsuki faltered. The explosions in his hands sputtered for a second. The script was wrong. Deku was supposed to be crying. Why was he smiling?

 

"What are you smiling at, you freak?!" Katsuki demanded, his voice wavering with a sudden, confusing insecurity.

 

Izuku didn't answer the question. He didn't defend himself. He didn't apologize. Instead, he raised his hand and extended it toward Katsuki, opening his fist.

 

Resting in Izuku's palm was a small, white paper bag.

 

"Would you care for a jelly baby, Kacchan?" Izuku asked casually.

 

Katsuki stared at the bag. He stared at Izuku's beaming face. His brain completely short-circuited. He had prepared for a fight, for a chase, for begging. He had absolutely zero defense against an aggressively cheerful offering of candy.

 

"What... what the hell is wrong with you?" Katsuki stammered, taking a subconscious step backward. The explosions in his palms died out entirely. He looked at Izuku as if the green-haired boy had suddenly grown a second head.

 

"They're really good," Izuku offered, his smile never wavering. "The strawberry ones are my favorite."

 

Katsuki's face flushed red, not with rage, but with utter, baffling embarrassment. He didn't know how to handle this. The power dynamic was entirely broken. He couldn't blast a kid who was happily offering him candy. It made him look insane.

 

"You're... you're a psycho, Deku!" Katsuki yelled, his voice cracking slightly. He spun around on his heel. "I don't have time for your weird garbage!"

 

With that, Katsuki stormed out of the clearing, marching back toward the playground as fast as he could, desperately trying to escape the confusing aura of the boy he thought he owned.

 

Izuku stood alone in the clearing. He lowered his hand.

 

He looked at the paper bag, then up at the clear blue sky above the pine trees. His heart was beating normally. His palms weren't sweaty. For the first time in his life, he had defeated Katsuki Bakugo without throwing a single punch.

 

He had won with a smile.

 

Izuku opened the bag, pulled out a strawberry jelly baby, and popped it into his mouth. He adjusted his backpack straps, turned around, and began the walk home, whistling a terribly off-key, but incredibly joyful, sea shanty.

 

 

The notebook was a standard, mass-produced composition book, its cover a mottled black and white marble pattern. To anyone else, it was fifty yen worth of cheap paper. To eight-year-old Izuku Midoriya, it was a sacred text.

 

Across the front cover, written in careful, blocky kanji, were the words: Hero Analysis for the Future, Vol. 1.

 

Izuku sat on the edge of a brick planter box in the middle of a bustling Musutafu shopping district, his pencil moving frantically across the lined paper. Fifty yards away, a minor villain with a Quirk that allowed him to shoot highly pressurized streams of mud from his pores was currently attempting to rob a jewelry store. He was being subdued by the Pro Hero, Death Arms.

 

The fight was over quickly. Death Arms used his immense physical strength to rip a lamppost from the concrete, swinging it like a giant baseball bat to knock the sludge-villain into the side of a parked delivery truck. The crowd of onlookers cheered, clapping politely as the police moved in with Quirk-suppressing handcuffs.

 

Izuku’s pencil scratched furiously.

 

Death Arms.

Quirk: Super Strength.

Notes: Incredible lifting power. Excellent muscle mass. He used the lamppost to increase his reach because the villain had ranged attacks! So cool! He’s really strong!

 

Izuku stopped, biting the end of his pencil. He looked at the words. He read them over twice. A small frown creased his forehead.

 

Two years had passed since his encounter with the bohemian man in the ridiculously long scarf. Izuku had taken the Fourth Doctor’s lessons to heart. He no longer cried when Katsuki bullied him; he deflected, he smiled, and on one memorable occasion, he offered the explosive boy a piece of pickled radish, which had confused Katsuki so deeply he had just walked away in a furious stupor. Izuku practiced his Venusian Aikido every single morning. He was agile, he was calm, and his mind was open.

 

But as he looked at his notebook, he felt a creeping sense of inadequacy.

 

He was eight years old now. He understood that smiling at a villain wouldn't stop a bank robbery, just as dodging Katsuki wouldn't save someone trapped in a burning building. If he was going to be a hero without a Quirk, he needed more than agility and absurdity. He needed a way to fight back. He needed to understand how power worked.

 

That was the purpose of the notebook. If he couldn't have a Quirk, he would understand everyone else's.

 

Yet, looking at his notes on Death Arms, Izuku felt frustrated. He's really strong. What kind of analysis was that? It was the observation of a fanboy, not a hero. What good did knowing Death Arms was strong do for someone who had the muscle mass of a wet noodle?

 

Izuku closed the notebook with a sigh, slipping it into his yellow backpack. The police were cordoning off the area. The show was over. He hopped off the planter and began the walk back to his apartment, his mind churning with unanswered questions. How does a normal person defeat someone who can lift a car? How do you stop a villain made of mud if you can't punch them?

 

He was so deep in thought that he didn't notice the sudden shift in the atmosphere until he turned down the narrow alleyway that served as a shortcut to his block.

 

The alley was usually filled with the sounds of stray cats and the low hum of air conditioning units. Today, it was dead silent. The air grew suddenly cold, a crisp chill that felt entirely out of place for a Japanese summer afternoon. The ambient light of the setting sun seemed to dim, casting long, strange shadows against the brick walls.

 

Izuku stopped dead in his tracks. The hairs on his arms stood on end. He knew this feeling. It was the atmospheric pressure drop. It was the localized static charge.

 

Vworp. Vworp. Vworp.

 

The sound echoed off the alley walls, a rhythmic, wheezing groan of an ancient engine fighting its way through the fabric of reality. The air in front of a rusted dumpster shimmered, violently twisting light and shadow until a solid, blue wooden box dropped onto the concrete with a heavy, resonant thud.

 

The TARDIS.

 

Izuku’s heart leaped into his throat. It had been two years. A part of his logical, growing brain had begun to rationalize the previous encounters as highly vivid dreams or trauma-induced hallucinations. But here it was. The impossible box.

 

He didn't hesitate. He ran forward, grabbed the small brass handle, and pushed the door open.

 

He stepped over the threshold, expecting the brilliantly lit coral pillars of the first two Doctors. But as the door clicked shut behind him, Izuku realized the TARDIS had changed again.

 

The console room was vast, but it was much darker than he remembered. The bright, sterile lighting had been replaced by a low, warm, moody ambiance. The coral pillars were gone, replaced by towering gothic arches and heavy, ornate wooden panels that looked like they belonged in a Victorian library. The central console was less clinical and more steampunk, a chaotic assembly of brass dials, heavy switches, and glowing glass tubes. Books were piled everywhere—on the floor, on the console, overflowing from armchairs.

 

The room smelled of old paper, Earl Grey tea, and ozone.

 

"Check," a voice said calmly.

 

Izuku turned. To the left of the console, sitting in a high-backed leather chair, was a man. He was shorter than the previous two Doctors, with a face that managed to look simultaneously avuncular and fiercely intimidating. He wore a light, checked suit with a beige pullover, a panama hat pushed back on his head, and a red paisley tie. Hooked over the arm of his chair was an umbrella with a handle shaped like a large, red question mark.

 

The man was hunched over a finely carved wooden chessboard, studying the pieces with intense, unblinking concentration.

 

He moved a white knight. "Checkmate."

 

Izuku walked closer, peering over the edge of the board. The man was playing alone.

 

"Um... excuse me?" Izuku said softly, bowing his head. "Are... are you the Doctor?"

 

The man didn't look up immediately. He slowly, deliberately knocked the black king over with his index finger. Only then did he turn his gaze to Izuku. His eyes were dark, piercing, and held a depth of ancient, calculating sorrow that made Izuku’s breath catch. This was not the flamboyant dandy, nor the bohemian madman. This man felt dangerous.

 

"I am," the Doctor said. His voice was soft, melodic, with a rolling Scottish burr that gave his words a rhythmic, almost hypnotic cadence. "And you, I deduce, are the anomaly. The chronal tether. You’ve grown since our last encounter, Izuku Midoriya."

 

Izuku nodded nervously. "You remember me? I thought... the last Doctor said when you change, you get a new brain."

 

"A new brain, yes. A new personality, certainly. But the memories remain," the Doctor said, standing up. He grabbed his umbrella, leaning on it slightly. "The First... well, my third incarnation, taught you how to use your body. The Fourth taught you to use your spirit. But you are troubled today, Izuku. I can see it in your eyes. You have reached a plateau."

 

"I... I have?" Izuku asked, surprised.

 

The Doctor walked over to Izuku and tapped the yellow backpack with the curved handle of his umbrella. "You observe. You take notes. You wish to be a hero in a world of supermen. But you are realizing that simply watching the pieces move on the board does not make you a player. It merely makes you an audience member."

 

Izuku felt a flush of embarrassment. It was exactly what he had been feeling. "I don't know how to fight people with Quirks. I don't have power. I can dodge, and I can distract, but I can't stop them."

 

The Doctor smiled, but it was a small, enigmatic thing. He turned away, walking toward the central console and resting his hands on the brass railings.

 

"Power," the Doctor mused, rolling the 'R'. "A fascinating concept. The brutes of your world believe power is the ability to break things. But true power, Izuku, is not the hammer that shatters the stone. True power is knowing exactly where to tap the stone so it shatters itself."

 

The Doctor began to flip switches and turn dials. The central rotor began to rise and fall, casting a pulsing, amber light across the dark room.

 

"Where are we going?" Izuku asked, the familiar thrill of the TARDIS flight returning.

 

"To a place where physical power is entirely useless," the Seventh Doctor replied softly, staring deeply into the swirling vortex of the time rotor. "To the Silver Citadel. A deep-space mining and research station in the year 2525. And more importantly, we are going to meet the perfect enemy. An enemy that cannot be reasoned with, cannot be intimidated, and certainly cannot be defeated with a smile or a jelly baby."

 

The TARDIS lurched violently, but the Doctor didn't stumble. He stood perfectly still, anchored by his umbrella, his eyes fixed on the monitors.

 

"Take out your notebook, Izuku Midoriya," the Doctor commanded. "Today, you stop being a fan. Today, you learn how to be a chess master."

 

 

 

The TARDIS materialized with its signature groan, but the moment the sound faded, it was replaced by a deafening, blaring klaxon. Red emergency lights bathed the console room through the scanner screens.

 

The Doctor calmly opened the wooden doors.

 

Izuku stepped out behind him, his notebook clutched tightly to his chest. They were standing in a wide, metallic corridor. The walls were made of cold, riveted steel, slick with condensation. The air was freezing, carrying the sharp, metallic tang of copper and ozone.

 

"What is this place?" Izuku shivered, his breath misting in the frigid air.

 

"The lower access corridors of the Silver Citadel," the Doctor said, his voice barely audible over the wailing sirens. He checked a small pocket watch, snapping it shut with a click. "We are precisely on time. The breach occurred three minutes ago."

 

"Breach? Villain attack?" Izuku asked, pulling his pen out.

 

"Villains are motivated by greed, or anger, or ideology," the Doctor replied, leaning on his umbrella and looking down the dark corridor. "What is coming is motivated only by a cold, mathematical imperative. Listen."

 

Izuku stopped and strained his ears over the sirens. Beneath the blaring noise, he heard it.

 

Clomp. Clomp. Clomp.

 

It was a heavy, perfectly synchronized marching sound. It wasn't the erratic footsteps of a mob; it was the terrifying, rhythmic march of a machine. The floor vibrated with the sheer weight of whatever was approaching.

 

From the shadows at the far end of the corridor, figures emerged.

 

Izuku’s blood ran cold. They were tall, towering over seven feet. They looked like men, but they were entirely encased in silver, gleaming metal. Their faces were terrifying—smooth silver masks with blank, teardrop-shaped holes for eyes, and a rigid, unmoving slit for a mouth. Thick, ribbed tubes connected their massive chest plates to their heads. They carried heavy, brutal-looking energy rifles.

 

"Doctor," Izuku whispered, his voice trembling. "What are they?"

 

"Cybermen," the Doctor said flatly. He didn't run. He didn't draw his Sonic Screwdriver. He just stood there, watching them. "Once, a long time ago, they were organic, like us. But they feared death. They feared weakness. So, piece by piece, they replaced their bodies with metal and plastic. But in doing so, they found that emotions—love, fear, anger, compassion—interfered with their new, perfect logic. So they removed those too."

 

The Cybermen halted fifty yards away. The leader, its chest plate adorned with a black insignia, pointed its weapon at the Doctor and Izuku.

 

When it spoke, the sound made Izuku want to cover his ears. It was a loud, synthesized, monotone buzz, utterly devoid of inflection or soul.

 

"INTRUDERS DETECTED. YOU WILL BE UPGRADED. IF YOU RESIST, YOU WILL BE DELETED."

 

"Upgraded?" Izuku breathed.

 

"They want to make us like them," the Doctor explained calmly. "Cut away our brains, put them in a metal suit, and delete our humanity."

 

Izuku took a step back toward the TARDIS. "We have to run! We have to fight!"

 

"Do not move, Izuku," the Doctor commanded sharply. "And do not fight. You cannot fight a Cyberman. Their armor is impervious to conventional weaponry. They have no pain receptors. If you punch them, you will break your hand. If you shoot them, they will not flinch."

 

"Then what do we do?!"

 

"We observe," the Doctor said, his eyes narrowing. "Write this down. Open your notebook."

 

Izuku’s hands were shaking so badly he nearly dropped his pencil, but the absolute authority in the Doctor’s voice compelled him to obey. He opened to a blank page.

 

"What do you see?" the Doctor asked, as the Cybermen began to advance, their heavy metal boots echoing terribly in the corridor.

 

"They're... they're metal! They have big guns! They're strong!" Izuku stammered.

 

"Useless observations," the Doctor chided coldly. "That is what they want you to see. That is their armor. Look beneath it. Look at their structure. Look at their environment. Why are they walking? Why are they not running?"

 

Izuku swallowed hard, forcing himself to look at the terrifying silver giants. The fear was paralyzing, but the Doctor’s presence anchored him. He narrowed his eyes, forcing his brain into analysis mode.

 

"They're... heavy," Izuku said, his pencil scratching on the paper. "Their joints. The way they step. They don't bend their knees much. They lack agility."

 

"Good," the Doctor nodded. "They sacrificed mobility for armor. A heavy piece on the board. A rook. What else?"

 

The Cybermen raised their rifles. The air hummed with charging energy.

 

"SURRENDER. SURRENDER AND BE UPGRADED."

 

"Their voices!" Izuku realized, speaking faster now. "They all moved at the exact same time when the leader spoke. They didn't look at him. They just obeyed. They're connected!"

 

"Excellent," the Doctor smiled grimly. "A hive mind. They operate on a shared tactical network. Individual thought is irrelevant. They process information collectively. This makes them incredibly coordinated, but it also creates a structural flaw. If you feed bad information into the network..."

 

"They all believe it," Izuku finished, his eyes widening. He wrote it down quickly.

Weakness: Shared network. Blind obedience to logic. Poor mobility.

 

"Now," the Doctor said, finally raising his umbrella. "Let us test the board."

 

The Cyberleader fired. A blast of blinding white energy tore down the corridor.

 

The Doctor didn't dodge. He pressed a button on the handle of his umbrella. A localized, invisible forcefield flared to life, deflecting the energy blast into the ceiling. A shower of sparks rained down.

 

"Run," the Doctor said calmly.

 

They turned and bolted down a side corridor, the heavy footsteps of the Cybermen immediately picking up the pursuit behind them.

 

The Citadel was a labyrinth of industrial walkways, steam vents, and heavy blast doors. Izuku and the Doctor ran through the maze, the sirens wailing incessantly. Everywhere they looked, there were signs of a massacre. Deep scorch marks on the walls, blasted barricades. The station's crew had tried to fight the Cybermen with sheer force, and they had been slaughtered.

 

"Where are we going?" Izuku panted, struggling to keep up with the Doctor’s surprisingly swift pace.

 

"To the environmental control center," the Doctor replied, rounding a corner and slipping through a half-open blast door. "The Cybermen are trying to take the Citadel to use its communications array. They want to broadcast a conversion signal to the nearby colony worlds. We cannot allow that."

 

They burst into a massive, circular room filled with computer terminals, holographic projections of the station, and massive atmospheric scrubbers. It was empty. The crew here had already fled or been taken.

 

The Doctor rushed to the main console, his hands flying across the alien keyboards with blinding speed. "They are tracking our heat signatures. They will be here in exactly forty-seven seconds. We have only one move to play."

 

Izuku ran to the door, looking out the reinforced glass window. He could see the silver shapes marching down the hall. There were dozens of them now. An entire platoon.

 

"Doctor, we're trapped!" Izuku yelled. "There's no other way out of this room!"

 

"I know," the Doctor said, not looking up from the console.

 

"Can you build a weapon? Like the Sonic Screwdriver thing?"

 

"I am not building a weapon, Izuku. I am setting a trap." The Doctor pulled a heavy lever, and the holographic display shifted, showing the ventilation schematics of the station. "You noted that they lack agility, and they rely on their network. But you missed one crucial detail. Their armor."

 

The Doctor pulled a sleek, silver Sonic Screwdriver from his pocket—different from the 4th Doctor's, this one had a red emitter. He jammed it into a data port on the console, the machine whining as it interfaced with the station's mainframe.

 

"Cybermen originated on a planet called Mondas," the Doctor explained rapidly. "To survive, their armor is incredibly resilient. However, to process their organic components, their internal respiratory systems are highly sensitive to certain non-corrosive, highly conductive elements. Specifically, aurum."

 

"Aurum?" Izuku asked, his mind racing through his middle-school science knowledge. "Gold?"

 

"Precisely," the Doctor smiled. "Gold dust coats their respiratory vents, preventing them from filtering oxygen. It chokes them. It is their ultimate weakness."

 

The Doctor pointed his umbrella toward the massive air scrubbers in the back of the room. "This station is a mining facility. They extract precious metals from the local asteroid belt. The air scrubbers are filled with a secondary filtration layer composed of pulverized gold to catch microscopic contaminants. I am currently reprogramming the ventilation system to reverse the airflow and flush the gold dust directly into this sector."

 

Izuku’s face lit up. "That's brilliant! We'll choke them!"

 

"There is a problem," the Doctor said, his voice dropping. He stepped back from the console. The screen flashed a bright red error message: MANUAL OVERRIDE REQUIRED AT JUNCTION 4.

 

The heavy thud of the Cybermen reached the blast doors outside.

 

"The cyber-virus they uploaded to the station's mainframe has locked out the remote command for the scrubbers," the Doctor said calmly. "The system requires a physical, manual release."

 

He looked at the far wall. High above the floor, nestled between two massive, humming pipes, was a heavy red lever. It was positioned precariously over a narrow, grated catwalk that looked barely stable enough to hold a cat, let alone a man.

 

"I am too heavy," the Doctor stated. "If I step on that grating, it will collapse, and the lever will remain unpulled."

 

The blast doors shuddered violently as the Cybermen began to pound against them.

 

BANG. BANG. BANG.

 

The Doctor turned his piercing gaze to Izuku.

 

"This is the board, Izuku," the Doctor said, his voice cutting through the panic. "The Cybermen are the pawns. The gold dust is the trap. But a trap is useless if the final piece is not moved into position. You are the only one who can reach that lever."

 

Izuku looked up at the catwalk. It was twenty feet in the air. He looked back at the blast doors, which were beginning to buckle under the immense, mechanical strength of the Cybermen.

 

Fear seized him again. What if he fell? What if the Cybermen broke through before he reached it? He had no Quirk. He was just a kid.

 

"I... I can't," Izuku whispered. "I'm just a normal kid."

 

The Doctor slammed the ferrule of his umbrella hard against the metal floor. The sound cracked like a whip.

 

"Normal?" the Doctor snapped, his eyes blazing with an intense, terrifying fire. "Do you think the universe cares about 'normal'? Do you think those machines outside care if you have a biological mutation? They do not! They see you only as raw material."

 

The Doctor stepped forward, grabbing Izuku by the shoulders. His grip was remarkably strong.

 

"You want to be a hero, Izuku Midoriya? A hero is not someone who is handed power! A hero is someone who looks at an impossible board, finds the one sequence of moves that leads to victory, and has the absolute, unshakeable will to execute it! Now, climb!"

 

The blast door groaned loudly, the metal tearing down the middle. A silver, three-fingered hand punched through the gap.

 

Izuku’s hesitation vanished, replaced by the sheer, imposing will of the Time Lord. He didn't think about his lack of a Quirk. He thought about the board. He thought about the pieces.

 

He ran to the wall. There was a series of exposed pipes leading up to the catwalk. He remembered the Venusian Aikido—balance, core strength, fluid movement. He didn't just climb; he scrambled up the pipes like a squirrel, his small size and light weight allowing him to use handholds the Doctor could never have managed.

 

"INTRUDERS. YOU ARE TRAPPED."

 

The blast door was ripped off its hinges, crashing to the floor with a deafening clang.

 

The Cyberleader stepped into the room, followed by a dozen more. They marched with mechanical precision, fanning out to cover all angles. They immediately locked onto the Doctor, who stood calmly in the center of the room, leaning on his umbrella.

 

Izuku reached the catwalk. He carefully pulled himself onto the rusted grating. It creaked dangerously under his small weight, but it held. He crawled forward, his eyes fixed on the red lever.

 

"THE DOCTOR," the Cyberleader buzzed, recognizing the Time Lord. "YOUR REGENERATIONS ARE IRRELEVANT. YOU WILL BE UPGRADED."

 

"I think not," the Doctor replied smoothly. "You see, you have made a fundamental miscalculation in your logic."

 

The Cybermen raised their weapons, taking aim at the Doctor’s chest.

 

Up on the catwalk, Izuku reached the lever. He grabbed it with both hands. It was rusted, stuck fast. He pulled with all his might, his feet slipping on the grating. It wouldn't budge.

 

"Your logic dictates that you are the superior force in this room," the Doctor continued, raising his voice to ensure it carried over the hum of the machinery. He subtly glanced up at Izuku. "You calculate variables based on visible threats. But you fail to account for the unseen. You fail to account for the pawns."

 

Izuku gritted his teeth. He remembered the scrapyard. He remembered leverage. He didn't just pull with his arms. He adjusted his footing, wrapped his arms around the lever, and dropped his entire body weight backward, using his center of gravity to force the mechanism.

 

With a loud CRACK, the rust broke. The lever slammed down.

 

"WHAT IS HE DOING?" a Cyberman asked, its mechanical head snapping up to look at Izuku.

 

It was too late.

 

Deep within the walls of the station, massive valves snapped open. The air pressure in the room instantly inverted. From the giant ventilation grates lining the ceiling and floor, a massive, swirling cloud of glittering gold dust erupted into the room.

 

It was beautiful and terrifying. The room was instantly filled with a blinding, golden fog.

 

The reaction was instantaneous.

 

The Cybermen, caught completely off guard, inhaled the dust through their chest units. The gold particles immediately coated their respiratory vents.

 

The Cyberleader staggered backward, dropping its weapon. It reached up, clawing helplessly at its chest plate. A horrible, wheezing, grinding sound emanated from its vocal processor, like a dying engine.

 

"SYSTEM FAILURE. RESPIRATORY BYPASS... BYPASS FAILING. MALFUNCTION."

 

All across the room, the terrifying silver giants collapsed. They fell to their knees, their limbs seizing as their organic components were starved of oxygen. They thrashed wildly, but their perfect armor was entirely useless against the microscopic threat choking them from the inside.

 

The Doctor quickly pulled a breathing mask from his pocket, strapping it over his face. He looked up at Izuku, who was high above the thickest part of the cloud, coughing slightly but safe.

 

Within thirty seconds, the room was silent. The entire platoon of Cybermen lay dead on the floor, their silver armor glittering under the coating of gold dust.

 

The Doctor walked over to the console and reversed the ventilation, sucking the remaining gold dust out of the air and sealing the room. He removed his mask and looked down at the fallen Cyberleader.

 

"Checkmate," the Doctor said softly.

 

He looked up at the catwalk. Izuku was carefully climbing back down the pipes. When his boots hit the floor, his knees buckled slightly, the adrenaline leaving his system in a rush.

 

The Doctor walked over to him. The terrifying, intense fire in his eyes had faded, replaced by that deep, avuncular warmth. He reached out and placed a hand on Izuku’s shoulder.

 

"Are you alright, Izuku?"

 

Izuku looked at the bodies of the Cybermen. They had been unstoppable. They had killed the station crew. They were walking tanks. And they had been defeated by dust and a pulled lever.

 

"We won," Izuku whispered, pulling his notebook out of his backpack. His hands were still trembling, but his mind was crystal clear. "You didn't fight them. You just... you changed the environment."

 

"I played the board," the Doctor corrected gently. "I observed their strengths—their armor, their network. I found the flaw—their respiratory systems, their lack of mobility. And I manipulated the environment to ensure that their strengths became irrelevant."

 

The Doctor took the notebook from Izuku’s hands. He flipped it open to the page on Death Arms. He read the notes.

 

"Death Arms," the Doctor read aloud. "'Quirk: Super Strength. He’s really strong.' Tell me, Izuku, after what you have just seen, how would you defeat a man with super strength?"

 

Izuku looked at the notebook, then at the Cybermen. The gears in his mind, dormant and frustrated for so long, suddenly locked into place and began to spin with terrifying efficiency.

 

"If he's strong... he relies on leverage and solid ground to lift things," Izuku said slowly, his voice gaining confidence with every word. "If you take away his footing—like oil on the ground, or fighting him on a fragile surface—his strength is useless because he can't anchor himself. Or, his muscles require massive amounts of oxygen. If you fight him in a sealed environment and restrict the airflow, his muscles will cramp and fail much faster than a normal person's."

 

The Doctor smiled. It was a proud, brilliant smile. He handed the notebook back to Izuku.

 

"Brilliant," the Doctor praised. "Absolutely brilliant. You see, Izuku? A Quirk is nothing more than a piece on the board. A knight can jump over other pieces. A bishop can strike from across the board diagonally. They are powerful. But the player who controls the board, who understands the environment and the weaknesses of the pieces, is the one who wins the game."

 

The Doctor turned and began walking back out the blast doors, stepping carefully over the fallen Cybermen. "Come along. The station's automated defense systems will reboot shortly and clear the rest of the drones. Our work here is done."

 

They walked back through the quiet corridors of the Citadel, leaving the carnage behind.

 

"Doctor?" Izuku asked as the blue doors of the TARDIS came into view.

 

"Yes, Izuku?"

 

"Is it... is it okay to think like that?" Izuku asked, a hint of guilt in his voice. "Looking at heroes and villains and only seeing their weaknesses? It feels... mean. Like a villain."

 

The Doctor stopped in front of the TARDIS doors. He turned, leaning on his umbrella, and looked at the eight-year-old boy with profound seriousness.

 

"A knife can be used to prepare a meal, or it can be used to take a life," the Doctor said softly. "The knowledge of weakness is not inherently evil. It is a tool. Villains use that knowledge to destroy. Heroes use that knowledge to protect, to disarm, and to save lives without causing unnecessary harm."

 

The Doctor tapped Izuku’s chest, right over his heart. "You have a good heart, Izuku Midoriya. You wish to save people. Do not be ashamed of sharpening your mind into a weapon to achieve that goal. In a world full of biological gods, your intellect is the only shield you need."

 

They stepped back into the dark, cozy console room. The TARDIS immediately began its groaning dematerialization sequence.

 

"The tether is pulling you back," the Doctor said, walking over to the console and watching the monitors. "Your time with me is over."

 

Izuku gripped his notebook tightly. "Thank you, Doctor. For teaching me how to play."

 

The Doctor turned, lifting his panama hat slightly in a gesture of profound respect. "The honor was mine, Izuku Midoriya. Remember: observe everything. Assume nothing. And never, ever let them see the trap until the cage is already locked."

 

The tingling sensation returned. The dark, Victorian console room began to fade into white light.

 

"Checkmate, my boy," the Doctor’s voice echoed softly.

 

Izuku blinked.

 

He was standing in the alleyway behind his apartment building. The sun had set, casting long, peaceful shadows across the brick walls. The sounds of traffic and the distant hum of the city returned.

 

The TARDIS was gone.

 

Izuku stood in the alley for a long time. He felt different. The crippling sense of inadequacy that had plagued him all afternoon was completely gone. He no longer felt like a helpless spectator in a world of giants. He felt awake. He felt dangerous.

 

He walked the rest of the way home, his mind buzzing with calculations, trajectories, and environmental variables. When he got to his room, he didn't turn on an All Might video.

 

He sat at his desk, turned on his lamp, and opened his notebook.

 

He flipped past the page on Death Arms. He turned to a fresh, blank page. He grabbed a red pen.

 

At the top of the page, he wrote a new heading.

 

Target: Katsuki Bakugo.

Quirk: Explosion.

 

Izuku stared at the name. He didn't see his childhood friend. He didn't see an unbeatable bully. He saw a piece on a board.

 

Primary mechanism: Izuku wrote, his pen flying across the page. Ignition of nitroglycerin-like sweat. Weakness: Relies on localized friction and heat. Highly dependent on emotional state (anger increases sweat production, but decreases tactical reasoning).

 

Izuku tapped his pen against his chin, his emerald eyes cold and calculating.

 

Environmental counter-measures: High humidity environments weaken ignition capability. Severe cold restricts sweat gland production entirely. If drawn into a prolonged, evasive engagement in a cold environment, his Quirk will be rendered functionally inert within fifteen minutes.

 

Izuku filled three entire pages with tactical breakdowns, psychological profiles, and environmental strategies to completely dismantle Katsuki Bakugo. He didn't write down a single punch or kick. He wrote down how to beat him before the fight even started.

 

When he finished, Izuku closed the notebook. He leaned back in his chair and looked at his hands. They were small. They were Quirkless. But they belonged to a chess master.

 

A small, chilling smile spread across Izuku Midoriya's face.

 

Your move, Kacchan.
