What if Deku Was the Smartest Hero Alive

 

 

The clinical sterility of Dr. Tsubasa’s office always smelled faintly of rubbing alcohol, latex, and an underlying scent of stale coffee. For most four-year-olds, the environment was highly distressing, a sensory trigger for impending needle pricks or cold stethoscopes.

 

Izuku Midoriya was not like most four-year-olds.

 

While his mother, Inko, nervously twisted the fabric of her skirt in her lap, Izuku sat on the examination table, legs dangling over the edge. He wasn't playing with his limited-edition All Might action figure in the traditional sense. He had unscrewed the small plastic bolt in the hero’s shoulder joint using a hairpin he had discreetly acquired from his mother’s purse. He was currently examining the tensile strength of the internal elastic band that allowed the arm to snap back into a punching motion, mentally cataloging the cheap manufacturing shortcuts of mass-produced hero merchandise.

 

“Mrs. Midoriya,” Dr. Tsubasa sighed, adjusting his round spectacles. He held a clipboard in one hand and a series of translucent neuro-imaging films in the other. “I’m afraid I have definitive news regarding Izuku’s Quirk status. As you know, we took some X-rays of his feet, alongside the standard cognitive and neurological scans you requested after his… rather unusual developmental milestones.”

 

Inko leaned forward, her green hair falling over her anxious face. “Yes? Is it a telekinetic Quirk like mine? Or fire-breathing like his father’s? He’s been speaking in full, complex sentences since he was fourteen months old, Doctor. He reads college-level textbooks. It has to be an Intelligence Quirk, right?”

 

Dr. Tsubasa clipped the X-ray onto the light board. The stark white bones of a child’s foot glowed against the dark background. He pointed a pen at the pinky toe. “You see this? It’s two joints. A genetic marker left over from a bygone era of human evolution. People with Quirks have evolved past this, possessing only a single joint for streamlined balance. Izuku has two.”

 

Inko let out a soft, shattered gasp. “He’s… Quirkless?”

 

“Biologically speaking, yes,” the doctor said, his tone carrying the heavy, practiced sympathy of a man used to delivering bad news. “He will not develop a superhuman ability, emit fire, or move objects with his mind.”

 

Izuku didn't cry. He didn't drop his toy in despair. He simply paused his dismantling of the plastic arm, his large emerald eyes shifting from the toy to the X-ray on the board. He looked at the bones. He understood the physiological implications immediately. Evolution was a process of shedding the unnecessary; the extra joint was a vestigial trait, much like the appendix.

 

“However,” Dr. Tsubasa continued, his voice shifting from sympathetic to profoundly bewildered. He pulled down the foot X-ray and replaced it with a multi-colored functional MRI scan of a brain. It looked like a topographical map of a galaxy, lit up with intense, blazing spots of red, yellow, and white neural activity.

 

“This,” the doctor said, almost reverently, “is your son’s brain under a baseline resting state. Mrs. Midoriya, an average human uses a highly efficient, compartmentalized network of neurons. Even individuals with registered Intelligence Quirks usually only show heightened activity in specific sectors—usually the frontal lobe for problem-solving or the hippocampus for memory.”

 

Dr. Tsubasa turned to look at the small, green-haired boy. Izuku blinked back, his expression entirely placid, absorbing every syllable.

 

“Izuku’s brain,” the doctor breathed, “is an anomaly. An absolute, unprecedented anomaly. His entire cerebral cortex is constantly firing, cross-referencing, and creating new neural pathways at a rate that defies modern medical science. His synaptic firing speed borders on the superhuman. He possesses eidetic memory, yes, but it goes far beyond that. He doesn't just remember information; his brain continuously analyzes, deconstructs, and runs predictive algorithms on everything around him. He is constantly processing a staggering amount of sensory and factual data without suffering from sensory overload.”

 

Inko looked dizzy. “I… I don't understand. If it’s not a Quirk… what is it?”

 

“It’s a mutation, but not the kind brought about by the luminescent baby in Qing-Qing City,” the doctor explained. “It is an organic, pure genetic lottery. If a Quirk is a biological magic trick, your son is a biological super-computer. His IQ cannot be accurately measured by our current testing models because he solves the spatial and mathematical equations faster than the examiner can flip the page. I have never seen anything like it.”

 

Inko looked at her son, tears welling in her eyes, a complex mix of sorrow for his Quirklessness and overwhelming awe. “Izuku…”

 

Izuku tilted his head. He looked at the MRI scan. Then, in a calm, clear, and terrifyingly steady voice for a toddler, he asked, “Doctor Tsubasa. The hyper-connectivity in my prefrontal cortex, combined with the continuous synaptic firing—does it require a higher caloric intake to maintain homeostasis? The brain consumes approximately twenty percent of the body's resting metabolic energy. Given the density of my neural networking shown on that film, I would hypothesize my brain requires upwards of forty-five percent. Am I at risk of chronic hypoglycemic shock if my dietary glucose isn't heavily monitored?”

 

The doctor stared at the four-year-old. The pen slipped from his fingers and clattered onto the linoleum floor.

 

“...Yes,” the doctor squeaked out, entirely unnerved. “Yes, we will need to adjust your diet.”

 

Izuku nodded, satisfied. He returned his attention to the All Might toy, deftly reassembling the internal elastic band with the tip of the hairpin, mathematically calculating the exact tension required for a flawless, spring-loaded punch.

 

He didn't have a Quirk. That was fine. A Quirk was just a specialized tool.

 

Izuku Midoriya had the entire hardware store.

 

 

 

Ten Years Later.

 

Aldera Junior High was an ecosystem.

 

To the average student, it was a loud, obnoxious purgatory of hormones, cheap cologne, and oppressive academic expectations. To Izuku Midoriya, sitting quietly in the back corner of Classroom 1-A, it was a closed-system terrarium governed by predictable sociological hierarchies and psychological fragility.

 

Izuku tapped his mechanical pencil against his notebook, his eyes tracking the micro-movements of his classmates. He processed their behaviors subconsciously.

 

Takeshi, two rows ahead. Tapping his heel at 120 beats per minute. Pupil dilation increased. Sweating slightly. He forgot to study for the math quiz next period. Consequence: He will try to copy off of Sato.

 

Sato. Posture rigid. Looking repeatedly at the clock. Breathing shallow. She’s anxious about her afternoon track tryouts, specifically her left ankle, which she keeps shifting her weight off of. Slight micro-tear in the Achilles tendon, likely sustained over the weekend.

 

And then, there was Katsuki Bakugo.

 

Izuku’s green eyes slid over to the ash-blonde teenager leaning back in his chair, feet propped disrespectfully on the desk. Katsuki’s posture screamed performative dominance. His jaw was clenched—a sign of bruxism, likely brought on by internal stress and an obsessive need for perfection. Small wisps of smoke curled from his palms.

 

Explosion Quirk. Nitroglycerin-like sweat glands. Highly volatile, but heavily dependent on hydration and ambient humidity. Psychological profile: Narcissistic superiority complex masking a deep-seated inferiority neurosis. Needs constant validation through physical intimidation. Predictable.

 

Izuku wasn't the trembling, stuttering mess he could have been. A mind that moved at Mach 3 left very little room for fear. Fear was an evolutionary response to the unknown. To Izuku, very few things were unknown. He understood the mechanics of his bullies, and therefore, he could not bring himself to fear them. He only found them exhausting.

 

"Since you're all third years, it's time for you to think seriously about your futures!" the homeroom teacher announced, dramatically tossing a stack of career aptitude papers into the air. "I'll pass out handouts for your future plans now, but... you're all pretty much planning to go into the hero course, right?!"

 

The classroom erupted. Students activated their Quirks—stretching limbs, glowing eyes, minor elemental parlor tricks. It was a cacophony of wasted energy.

 

"Yes, yes, you all have wonderful Quirks," the teacher sighed, waving his hands. "But using your powers in school is against the rules!"

 

"Sensei! Don't lump me in with these background characters!"

 

Katsuki’s voice cut through the noise, loud, abrasive, and perfectly calculated to draw the room’s entire attention. He smirked, leaning back in his chair. "I'm not gonna be stuck at the bottom with the rest of these rejects."

 

The class erupted in predictable outrage. Izuku internally groaned, continuing to sketch a highly complex schematic of a dual-compression grappling hook in his notebook. The math was tricky. He needed a specific carbon-nanotube weave to withstand the kinetic shock of a sudden deceleration, but Aldera High’s computers were too slow to run the simulation he needed. He would have to bypass the firewall at the local public library later.

 

"Oh, if I remember correctly, you want to go to U.A. High, right, Bakugo?" the teacher noted, looking at his clipboard.

 

The room went silent, then broke into impressed murmurs. The national acceptance rate for U.A. was abysmal. Only the absolute elite even bothered applying. Katsuki stood up, leaping onto his desk with a triumphant grin, basking in the spotlight. He began a well-rehearsed monologue about his test scores, his power, and his destiny to surpass All Might.

 

"Oh, yeah," the teacher interrupted, squinting at his sheet. "Midoriya wants to go to U.A., too, right?"

 

The silence that fell over the room this time was absolute. Every head turned toward the back corner.

 

Izuku didn't stop writing. He was in the middle of calculating the aerodynamic drag coefficient of a specialized smoke grenade.

 

"Midoriya?" someone snorted. "No way."

 

"He doesn't even have a Quirk!"

 

Before anyone else could speak, a massive explosion rocked Izuku’s desk. The force of the blast scorched the wood and blew Izuku’s notebook out of his hands, sending it clattering to the floor. The smell of burnt sugar and ozone filled the air.

 

Katsuki stood over him, his hand smoking, his red eyes narrowed into a glare of absolute, murderous fury.

 

"Listen up, Deku," Katsuki snarled, using the derogatory nickname he’d coined years ago. "You're worse than the rest of these damn rejects. You're completely Quirkless. You really think you can stand in the same ring as me? You think you can rub shoulders with the best? You're a pebble."

 

The room held its breath. They expected Izuku to cower. They expected him to throw his arms over his face, to stutter out an apology, to shrink into the floorboards as he had done when they were small children.

 

Instead, Izuku sighed. It was a soft, tired sound.

 

He calmly reached into his pocket and pulled out a small, microfiber cloth. He wiped a streak of soot off his cheek, then folded the cloth and put it away. He looked up at Katsuki. His emerald eyes were flat, analytical, and entirely devoid of fear.

 

"Your ignition time is lagging by approximately zero-point-two seconds, Katsuki," Izuku said.

 

His voice was crisp, entirely level, and completely unwavering. He didn't stutter. He spoke rapidly, the words flowing out of him like water from a high-pressure hose.

 

Katsuki blinked, thrown off balance. "...What did you just say to me?"

 

"Your explosion," Izuku continued, leaning back in his chair and folding his hands neatly on the charred remnants of his desk. "The ignition time is lagging. Your sweat production is currently sub-optimal, likely due to your refusal to hydrate properly. You skipped the water fountain after P.E. because you think carrying a water bottle makes you look weak. Consequently, the nitroglycerin analog in your sweat is highly concentrated but lacks the necessary volume for a rapid, sustained chain reaction. If you were in a real combat scenario right now, a villain with a basic speed-enhancement Quirk would exploit that zero-point-two-second lag and break your jaw before you could raise your palm."

 

The classroom was dead silent. The teacher froze, chalk in hand.

 

Katsuki’s face flushed a deep, dangerous crimson. The veins in his neck bulged. "You little piece of—"

 

"Furthermore," Izuku interrupted smoothly, his voice cutting through Katsuki’s rage like a scalpel, "your emotional volatility makes your attack patterns incredibly linear. You lead with a right hook eighty-five percent of the time because you are right-hand dominant, and you use your explosions to mask your physical tells. You are overcompensating, Katsuki. You project this aura of absolute superiority because you are fundamentally terrified that your Quirk is the only valuable thing about you. You believe that if someone without a Quirk—like me—can enter the same academic institution as you, it devalues your existence."

 

Katsuki’s hand began to tremble. Not from rage, but from a sudden, violent psychological shock. The sheer, unadulterated accuracy of Izuku’s words hit him harder than a physical blow. He felt exposed. He felt naked.

 

"Shut up," Katsuki whispered, his voice cracking slightly. "Shut up, Deku."

 

"I am applying to U.A. High School because it possesses the most advanced support engineering and tactical analysis programs in the hemisphere," Izuku stated, standing up calmly. He was shorter than Katsuki, but the way he held himself—perfectly balanced, utterly composed—made him seem imposing. "I have no interest in competing in your arbitrary hierarchy of raw, unrefined power. Intelligence is the ultimate equalizer. You break things, Katsuki. I understand them."

 

Izuku bent down, retrieved his lightly singed notebook, and tucked it under his arm. The bell rang, echoing loudly in the silent, tense classroom.

 

"I'll be taking my leave now, Sensei," Izuku said, bowing politely to the dumbfounded teacher. "I have off-campus research to conduct."

 

He walked out of the classroom. Katsuki stood frozen by the charred desk, his hands lowered, his breath caught in his throat. He looked around the room, expecting someone to laugh, to break the tension. But his classmates were just staring at the door, their expressions a mixture of shock and sheer, unadulterated terror.

 

They realized, perhaps for the first time, that Deku wasn't weak.

 

He was just playing a completely different game.

 

 

 

The late afternoon sun cast long, golden shadows across the pavement as Izuku walked home.

 

He preferred taking the route beneath the city overpasses. The concrete infrastructure provided excellent shade, and the relative quiet allowed his mind to process the day's data without unnecessary sensory interference. Currently, he was reviewing the footage he had recorded on his phone earlier that morning: the fight between the villain with the gigantification Quirk and the new heroine, Mount Lady.

 

"Kamui Woods had the situation entirely under control," Izuku muttered to himself, adjusting his earpods as he walked. "His Lacquered Chain Prison is a high-tensile restraint maneuver with minimal collateral risk. Mount Lady’s intervention, while visually spectacular and highly marketable, caused structural damage to the overpass infrastructure and fractured the main municipal water line running beneath the street. The city will have to spend roughly two million yen in repairs. Her public relations team will likely spin it as a necessary display of force, but strictly from a tactical perspective, it was incredibly inefficient."

 

He paused the video, zoomed in on Mount Lady’s landing trajectory, and calculated the kinetic force of a giant dropping from that height. He sighed. Heroes today were far too focused on flashy finishers and media presence. Very few treated heroism as what it truly was: high-stakes risk management.

 

Izuku pocketed his phone and adjusted his backpack. As he walked deeper into the shadowed tunnel of the underpass, his peripheral vision caught a slight distortion in the air.

 

Then, the smell hit him.

 

It was utterly vile. A mixture of raw sewage, rotting biomass, and a highly concentrated accumulation of methane gas.

 

Izuku stopped walking immediately. His brain shifted gears, abandoning the Mount Lady analysis and entirely dedicating its processing power to the immediate environmental anomaly.

 

Sound of a grate shifting behind me. Wet, viscous slapping against concrete. Smell of methane indicates organic decomposition.

 

He spun around.

 

Rising from the manhole behind him was a massive, undulating wave of dark green, gelatinous sludge. It had two large, manic eyes and a gaping, jagged mouth.

 

"A medium-sized meat-suit!" the sludge villain gurgled, its voice wet and guttural. "Perfect! Just what I need to hide from that bastard!"

 

Before Izuku could step back, the sludge lunged.

 

The physical impact was negligible, but the sheer volume of the liquid engulfed Izuku instantly. The sludge forced its way into his mouth, his nose, wrapping around his limbs and lifting him off his feet.

 

"Don't fight it, kid!" the villain laughed, his slimy tendrils tightening. "It'll only hurt for about forty-five seconds. Then it'll all be over. You're my hero!"

 

For a normal middle schooler, this was the end. The amygdala would hijack the brain, flooding the system with adrenaline and inducing a state of blind, suffocating panic. The victim would flail, waste oxygen, and rapidly succumb to asphyxiation.

 

Izuku Midoriya did not panic.

 

Panic was a chemical response, and Izuku had spent years training his prefrontal cortex to override his baseline emotional reactions through sheer, hyper-rational focus.

 

Status Assessment, his brain fired in milliseconds. I am engulfed in a sentient, non-Newtonian fluid. Airway is obstructed. Estimated time before loss of consciousness: fifty to sixty seconds. Estimated time before irreversible brain damage: three minutes. Physical resistance is useless; strikes will lack kinetic transfer as the fluid will simply absorb the force.

 

Izuku forced his eyes open, ignoring the sting of the toxic sludge. He looked at the villain's eyes. They were solid, physical constructs floating within the liquid mass. A weak point, but striking them wouldn't free him; it would only agitate the villain.

 

He needed a systemic shock. He needed to alter the physical state of the enemy.

 

Fluid analysis. The smell of methane is overpowering. Methane is highly combustible. The villain’s body is predominantly liquid, likely water-based given the sewer origin. What happens when a highly concentrated combustible gas is ignited within a water-based medium?

 

Flash-boil.

 

Izuku had exactly thirty seconds of oxygen left in his blood.

 

He didn't thrash. He moved with agonizing, deliberate precision. His right arm was pinned against his side, his hand hovering near his uniform pocket. He slowly, painstakingly forced his fingers into the pocket.

 

The villain noticed the movement. "I said stop fighting! You can't grab anything, kid! I'm fluid!"

 

Izuku’s fingers brushed against his everyday carry items. He always carried specific tools, a habit born from his analysis of urban survival scenarios. His fingers closed around three objects.

 

1. A heavy-duty, stainless-steel tactical pen.

2. A travel-sized can of aerosol deodorant.

3. A modified Zippo lighter, which he used for soldering wires in U.A. lab prep.

 

Twenty seconds. Izuku’s lungs burned. Dark spots danced in his vision. He had to execute this perfectly.

 

First, the pen. Izuku gripped the steel cylinder and, using the leverage of his pinned elbow, violently snapped his wrist upward, driving the point of the pen directly into the villain’s left eye.

 

"AGH!" The villain shrieked, the sludge recoiling instinctively from the sharp, targeted pain.

 

The grip around Izuku’s chest loosened just a fraction—enough for him to pull his arm free.

 

Ten seconds.

 

Izuku pulled the aerosol can and the lighter from his pocket. He brought them together in front of his chest, submerged within the thickest part of the sludge. He flicked the cap off the deodorant with his thumb. He sparked the modified Zippo. The flame roared to life, burning blue and hot.

 

He jammed the nozzle of the aerosol can directly against the flame and depressed the actuator.

 

The result was instantaneous. The pressurized aerosol propellant ignited, creating a concentrated, localized blowtorch. But the true devastation wasn't the fire itself; it was the chemical reaction with the villain’s methane-rich, water-based physiology.

 

The intense, sudden heat caused the fluid immediately surrounding the blast to vaporize. The methane gas trapped within the sludge ignited in a chain reaction. A muffled, concussive THUMP echoed through the underpass.

 

A thermobaric flash-boil.

 

The water inside the villain’s cellular structure rapidly expanded into steam. The villain let out an agonizing, ear-piercing scream as its entire body underwent a violent phase change. The intense heat forced the proteins in the sludge to denature and coagulate.

 

The villain literally solidified. The wet, shifting sludge turned into a hard, crusty, brittle shell of dried biomatter.

 

The grip shattered. Izuku fell to the concrete floor, landing hard on his hands and knees.

 

He coughed violently, expelling vile-tasting slime onto the pavement. He gasped for air, his lungs burning as they rapidly absorbed oxygen. He forced himself to take deep, measured breaths—in through the nose, out through the mouth—regulating his heart rate, pushing away the encroaching shock.

 

He looked up. The villain was a frozen, hardened statue of muck, its remaining eye darting around in absolute panic, completely paralyzed by the sudden evaporation of its liquid form.

 

"Fascinating," Izuku rasped, wiping his mouth with the back of his hand. "Rapid thermal expansion neutralized your kinetic mobility. You're effectively trapped in your own coagulated skin. You'll need at least three hours of ambient moisture absorption to regain fluidity."

 

Before Izuku could stand up and call the authorities, the manhole cover ten feet away was violently blown off its hinges. It flew through the air like a frisbee, embedding itself deep into the concrete ceiling of the underpass.

 

A massive, imposing figure erupted from the sewers.

 

"HAVE NO FEAR, CITIZEN!" a booming, larger-than-life voice echoed off the walls. "FOR I AM HERE!"

 

All Might stood in the underpass, striking a heroic pose, his fists planted on his hips, his iconic smile blazing. His massive musculature seemed to warp the very air around him. He looked ready to engage in a titanic clash of good versus evil.

 

Then, All Might blinked.

 

He looked at the frozen, crusty statue of the Sludge Villain. Then he looked at the small, green-haired middle schooler sitting on the pavement, coughing lightly and dusting off his school uniform.

 

The silence stretched for a deeply awkward moment.

 

"Ah," All Might said, his booming voice faltering slightly. "It appears... the situation is already resolved."

 

Izuku stood up slowly. He brushed the remaining dirt off his knees. He looked at the Number One Hero, the Symbol of Peace, the man who had inspired a generation.

 

Izuku didn't scream. He didn't faint. He didn't pull out a notebook with trembling hands.

 

He calmly reached into his pocket, pulled out his smartphone, and checked the time. Then, he looked All Might directly in the eyes.

 

"You are approximately four minutes and twenty seconds late," Izuku said, his voice returning to its rapid, clinical cadence.

 

All Might flinched. "...Excuse me?"

 

"You pursued this villain through the subterranean sewer system," Izuku stated, pointing a finger toward the open manhole. "A highly inefficient pursuit method for a hero of your physical stature. Your sheer mass and kinetic output in an enclosed space caused a subterranean pressure build-up. I felt the seismic vibrations three blocks away. You risked rupturing the city’s primary natural gas lines. Furthermore, by chasing him from below, you funneled him directly toward the surface access points, driving him into populated civilian areas. Your pursuit method increased the risk of civilian casualty by roughly thirty-four percent."

 

All Might stared down at the boy, utterly bewildered. The towering Symbol of Peace, a man who regularly wrestled natural disasters into submission, felt like he was being reprimanded by a seasoned tactician.

 

"I... well, you see, young man, the sewers were the most direct route—"

 

"The most direct route is rarely the safest," Izuku interrupted smoothly. He stepped closer, his emerald eyes scanning All Might’s towering form.

 

Izuku’s brain went into overdrive. He wasn't just looking at the hero; he was dissecting him.

 

Posture: rigidly straight, but overcompensating on the left side. He’s shifting his weight off his left hip. Breathing pattern: shallow, controlled, but there is a faint wheeze at the bottom of his exhale. Scent: sweat, ozone, and... copper. Iron. Blood. He’s hiding a severe, likely chronic, respiratory or internal injury. His smile is strained at the edges. The muscle mass is immense, but the vascularity suggests he is holding this form through sheer, agonizing exertion rather than natural stasis.

 

Izuku stopped analyzing. He had enough data. He didn't want to push his luck or reveal how much he had deduced from a ten-second interaction.

 

"However," Izuku continued, his tone softening slightly, "your arrival time, while flawed, was mathematically within the acceptable parameters to prevent a total mass-casualty event in a crowded sector. And your psychological impact on the populace is undeniable."

 

Izuku reached into his bag, pulling out his charred notebook and a pen. He held it out to the towering hero.

 

"Despite your tactical inefficiencies, your statistical success rate remains unprecedented. If you wouldn't mind, could I acquire your signature? It would be highly valuable for my personal archives."

 

All Might let out a booming laugh, though it sounded a bit relieved. He took the notebook. "HA HA HA! OF COURSE, YOUNG MAN! A HERO IS ALWAYS HAPPY TO OBLIGE A FAN! THOUGH, I MUST ADMIT, YOUR OBSERVATION SKILLS ARE QUITE SHARP!"

 

All Might scribbled his massive, sprawling signature across a two-page spread and handed it back.

 

"Thank you," Izuku said, bowing politely. "I suggest you secure the villain in a sealed, airtight container. A standard two-liter soda bottle should suffice, given his current coagulated density. Good day, All Might. Please consider taking a less destructive route back to your agency."

 

With that, Izuku turned on his heel and calmly walked out of the underpass, his posture perfect, his mind already spinning onto the next calculation.

 

All Might stood alone in the shadows, holding an empty soda bottle he had picked up from the street. He looked at the retreating back of the green-haired boy, then down at the hardened villain, then back at the boy.

 

Suddenly, a sharp pain tore through All Might's side. He coughed violently, a spray of blood splattering against his hand. His massive form shuddered, steam rising from his skin as he struggled to maintain his muscle form.

 

That boy... All Might thought, wiping the blood from his mouth, his blue eyes wide with a mixture of shock and profound curiosity. He didn't just notice my mistakes. He looked right through me. Who in the world is he?

 

 

 

Meanwhile, at U.A. High School.

 

The principal’s office at U.A. High was a sanctuary of high intelligence and refined taste. Leather-bound volumes of law, advanced physics, and classic literature lined the walls. A custom-built tea set sat on a polished mahogany desk.

 

Sitting behind the desk, humming a cheerful, erratic tune, was Principal Nezu. He was a creature that defied biological classification—a chimera of a dog, a mouse, and a bear, dressed in a perfectly tailored waistcoat.

 

Nezu was, by all metrics, the smartest being on the planet. His Quirk, High Spec, granted him an intellect that vastly surpassed human comprehension. He viewed the world as a complex chessboard, moving pieces, predicting outcomes, and orchestrating the future of hero society. It was a lonely existence. It was rare—almost impossible—for Nezu to find anything that truly surprised him.

 

He was currently sipping a cup of Earl Grey tea, his black, beady eyes locked onto the massive array of computer monitors on his wall. He was monitoring the city’s police feeds, traffic cameras, and localized thermal satellite imaging. A hobby of his.

 

A red alert flashed on Monitor 4. Unauthorized quirk usage / Thermal Spike - Sector 4 Underpass.

 

Nezu clicked the alert, bringing up the street camera feed from the mouth of the tunnel. The camera angle was poor, partially obscured by shadows, but Nezu’s eyes missed nothing.

 

He watched the sludge villain attack. He watched a middle school boy in a black uniform get engulfed.

 

Nezu reached out a white, furry paw and was about to press the dispatch button to alert a nearby hero patrol. But then, he paused.

 

He leaned closer to the screen.

 

The boy wasn't thrashing. The boy wasn't panicking.

 

Nezu enhanced the image, zooming in on the boy’s face. He saw the cold, hyper-focused calculation in the child’s emerald eyes.

 

"Fascinating," Nezu murmured, setting his teacup down.

 

He watched, mesmerized, as the boy executed a flawless, multi-stage thermobaric reaction using everyday household items. He watched the flash-boil. He watched the boy free himself, drop to the ground, and calmly assess the defeated villain.

 

Nezu’s tail gave a slight twitch.

 

Then, All Might arrived. Nezu watched the interaction. The camera had no audio, but that didn't matter to Nezu. He was a master of reading lips, body language, and micro-expressions.

 

He read the boy’s lips as he ruthlessly, systematically, and flawlessly deconstructed All Might’s entry route, collateral damage potential, and tactical inefficiency. He watched All Might flinch, utterly dominated in the conversation by a child. He watched the boy calmly ask for an autograph and walk away.

 

Nezu sat back in his oversized leather chair.

 

For a long moment, the office was entirely silent save for the hum of the computer servers.

 

Then, a sound escaped Nezu’s throat. It started as a low chuckle, then grew into a bubbling, ecstatic laugh.

 

He spun his chair around, grabbing his custom-made tablet. His paws flew across the keyboard at blurring speeds, hacking into the national civilian registry, the local school district databases, and the medical boards. Within thirty seconds, he had the boy’s entire life file.

 

Midoriya, Izuku. Age: 14. Aldera Junior High. Quirk: None.

 

Nezu clicked on a secondary medical file attached to the birth record. An EEG brain scan from ten years prior.

 

Nezu stared at the glowing web of neural activity on the screen. The sheer density of the synapses. The impossible processing power.

 

Nezu smiled. It wasn't a cute, cuddly smile. It was the terrifying, predatory grin of a genius who had just found the missing variable in his grandest equation. For years, Nezu had looked at the hero society and saw a crumbling infrastructure. It relied entirely on brute force, on the singular, fading pillar of All Might. It was unsustainable. The world didn't need another heavy hitter. The world needed an architect.

 

"Quirkless," Nezu whispered, his smile stretching wider, revealing small, sharp teeth. "Oh, the sheer irony. The world dismissed you because you lack a parlor trick, completely blind to the fact that you hold the universe in your skull."

 

Nezu tapped a button on his intercom.

 

"Eraserhead," Nezu called out, his voice practically vibrating with excitement. "Please report to my office immediately. And cancel your patrol for tonight. We have a very, very special recruitment project to begin."

 

Nezu looked back at the frozen frame of Izuku walking away from All Might. The principal picked up his teacup and raised it in a silent toast to the screen.

 

"Checkmate," Nezu purred.

 

The Midoriya household was usually a quiet one. Ever since Izuku had been diagnosed as Quirkless, Inko had done her best to cultivate an environment of gentle, undisturbed peace, acting as a soft buffer between her son and a world that valued only superhuman spectacle.

 

But Izuku didn’t need a buffer. He needed stimulation.

 

His bedroom was a testament to a mind that refused to rest. Where other teenagers had posters of pop stars or superficial heroes, Izuku’s walls were covered in a chaotic but mathematically precise web of schematics, city grid blueprints, and criminal behavioral profiles. Stacks of notebooks detailing the physics of Quirks and the engineering flaws of modern support gear formed leaning towers across his desk. Currently, he was meticulously disassembling a broken microwave he had found in the alley, harvesting its magnetron to see if he could reverse-engineer a localized, directional microwave emitter.

 

A knock on the apartment’s front door broke his concentration.

 

Izuku’s hands stilled. He glanced at the digital clock on his desk: 8:14 PM.

 

Unscheduled visitor, his mind whirred. Mom is currently washing dishes; the water has been running for four minutes. The knock was low on the door frame, approximately three feet off the ground. A child? No, a child would knock with rapid, erratic force. This was a polite, measured double-tap with a distinct pause. An adult crouching? Unlikely. A non-human entity.

 

Izuku set down his screwdriver and walked out of his room just as Inko dried her hands on a towel and opened the front door.

 

"Hello?" Inko asked, looking down. Her eyes widened, and she took a startled step back. "Oh! Um... hello?"

 

Standing on the welcome mat was a creature that resembled a combination of a dog, a mouse, and a small bear. He was impeccably dressed in a tailored waistcoat, a crimson tie, and perfectly polished miniature oxfords. Behind him stood a tall, severely unkempt man in all black, wrapped in what looked like a thick, grey scarf. The man looked incredibly tired, his eyes framed by heavy dark circles.

 

"Good evening, Midoriya-san!" the creature chirped cheerfully, bowing at a perfect forty-five-degree angle. "I apologize for the late intrusion. I am Nezu, the Principal of U.A. High School. And this is Aizawa Shota, one of my esteemed faculty members."

 

Inko’s brain seemed to short-circuit. "U.A.? Principal? I... I don't... is Izuku in trouble?"

 

"On the contrary, Madam," Nezu said, his black, beady eyes scanning past her and locking onto Izuku, who had quietly stepped into the hallway. "Izuku is perhaps the least 'in trouble' young man I have encountered in a decade. May we come in?"

 

A few minutes later, the four of them were seated in the small living room. Inko had hastily brewed tea, her hands shaking so badly the cups rattled against the saucers. Aizawa stood leaning against the wall near the door, his posture relaxed but his eyes scanning the room with the practiced gaze of an underground pro hero.

 

Izuku sat perfectly still on the sofa opposite Nezu. He didn't look at the creature with awe or fear. He looked at him with an intense, calculated curiosity.

 

Principal Nezu. Quirk: High Spec. The only recorded animal in history to develop a Quirk that grants super-intelligence. Highly rational, strategically unmatched, known for complex, multi-layered problem-solving. Why is he in my living room?

 

Nezu took a sip of his tea. "Excellent blend, Midoriya-san. Truly." He set the cup down and smiled, revealing small, sharp teeth. "Now, to the matter at hand. Izuku, tell me, what did you think of All Might’s performance yesterday at the Sector 4 underpass?"

 

Inko gasped softly. "Izuku? You saw All Might yesterday?"

 

"I didn't just see him, Mother. We had a brief conversation," Izuku replied evenly, never taking his eyes off Nezu. "To answer your question, Principal: All Might is a statistical anomaly holding up a structurally compromised society. His performance yesterday was severely flawed. He prioritized speed over environmental spatial awareness, utilized a high-impact entry method in a subterranean, gas-heavy environment, and allowed a fluid-based villain to reach a civilian sector."

 

Aizawa let out a low, breathy sound. It might have been a scoff, or it might have been a laugh. "Told you, Nezu. He's a critic."

 

"Not a critic, Eraserhead," Izuku corrected without missing a beat, turning his gaze to the tired hero. "An analyst. And you are Aizawa Shota, Pro Hero Eraserhead. Quirk: Erasure. You nullify the Quirk factor of anyone you look at by temporarily blocking the genetic expression in their DNA. You work entirely underground because the media would compromise your tactical advantage. You also fight using a specialized capture weapon—a steel wire alloy woven with carbon nanofibers, likely designed to manipulate angular momentum to compensate for your lack of an inherent strength enhancement."

 

Aizawa froze. His lazy, half-lidded eyes suddenly sharpened into a dangerous, piercing glare. "How do you know about my gear, kid? That's classified."

 

"I extrapolated," Izuku said calmly. "I reviewed shaky smartphone footage of an underground raid in Naruhata three years ago. The tensile strain required to throw a two-hundred-pound villain with a single ribbon of fabric mathematically requires a carbon-nanotube base. The way it moves implies you control it dynamically, likely through a microscopic electrostatic charge woven into your gloves."

 

The living room fell silent. Inko looked back and forth between her son and the heroes, completely lost.

 

Nezu, however, was vibrating with absolute, unrestrained joy.

 

"Oh, this is marvelous. Simply marvelous!" Nezu clapped his paws together. "Aizawa, you owe me two thousand yen! I told you he didn't hack a database; he simply figured it out!"

 

Nezu leaned forward, his demeanor shifting from cheerful to intensely focused. The temperature in the room seemed to drop. When Nezu spoke next, it was no longer the polite principal speaking; it was a predator acknowledging a peer.

 

"Izuku Midoriya. You are Quirkless. But yesterday, I watched you neutralize a B-Rank villain using a travel-sized deodorant, a lighter, and a pen, utilizing a flawlessly executed thermobaric phase-change trap. I also watched you reprimand the Symbol of Peace with the clinical detachment of a general."

 

"I merely pointed out the tactical variables," Izuku said.

 

"And that is exactly why I am here," Nezu stated. "Hero society is stagnant, Izuku. We are churning out generations of hammers, and every problem is starting to look like a nail. We lack architects. We lack visionaries who understand that true heroism isn't just about punching harder; it's about systemic control, risk mitigation, and intellectual superiority. You intend to apply to U.A. High School's Hero Course, do you not?"

 

"I do. Though the practical exam heavily favors physical and emitter-type Quirks. The algorithmic bias against intelligence and support-based applicants is a well-documented flaw in your entry system," Izuku pointed out bluntly.

 

"A flaw I intend to rectify, with your help," Nezu smiled. "The Entrance Exam is in exactly ten months. I am offering you a proposition. The Nezu Protocol. For the next ten months, you will become my personal, private pupil. You will be given unrestricted access to U.A.'s Development Studios, raw materials, and my personal archives. Aizawa here will instruct you in close-quarters, Quirk-less combat. You will not just pass the Entrance Exam, Izuku. You will shatter the scoring curve so thoroughly that the Hero Commission will be forced to rewrite the rules."

 

Inko put her hand over her mouth, tears of shock welling in her eyes. "Izuku..."

 

Izuku looked at Nezu. He looked at Aizawa. He processed the variables. He calculated the resources U.A. possessed: millions of dollars in technological hardware, the most advanced metallurgical labs in the country, and the direct tutelage of an animal with an IQ in the thousands.

 

Izuku stood up from the sofa and bowed, exactly forty-five degrees.

 

"I accept your terms, Principal Nezu. When do we begin?"

 

"Tomorrow at 0500 hours," Aizawa grunted, pushing himself off the wall. "Don't be late, problem child."

 

 

 

The Dagobah Municipal Beach Park was less of a beach and more of an ecological disaster. Mountains of rusted refrigerators, crushed cars, and discarded electronics stretched for miles, a monument to illegal dumping and societal neglect.

 

Izuku stood at the edge of the sand, wearing heavy work boots, thick gloves, and a particulate mask. Nezu stood beside him, holding a small umbrella to block the morning sun.

 

"Most physical training regimes would have you clean this entire beach to build muscle," Nezu noted, gesturing with a paw. "It builds character, endurance, and cardiovascular health."

 

"It also risks tetanus, heavy metal poisoning, and repetitive stress injuries without adequate caloric compensation," Izuku countered, adjusting his mask. "Furthermore, my goal is not to become a bodybuilder. Excessive muscle mass decreases flexibility, increases oxygen consumption, and creates larger hitboxes in combat. I need lean, functional, fast-twitch muscle fiber."

 

"Precisely!" Nezu agreed cheerfully. "You are not here to clean the beach, Izuku. You are here to mine it."

 

Nezu handed Izuku a customized, heavy-duty crowbar and a set of high-grade wire cutters. "Within this refuse lies thousands of dollars worth of salvageable copper, titanium alloys, micro-processors, and hydraulic tubing. I have secured a private workspace for you at U.A.'s Development Studio. Your morning routine will consist of harvesting materials from this beach. The physical exertion of dismantling cars and carrying scrap will provide the functional muscle you require, while the materials will fund your engineering projects."

 

Izuku looked at the mountains of trash. Where others saw garbage, his mind instantly began highlighting valuable components in a heads-up display of his own imagination. Alternator from a 2012 sedan... copper coils inside that CRT television... reinforced steel suspension springs from that truck bed...

 

"Understood," Izuku said, gripping the crowbar. "I'll need a reinforced cart to transport the heavier alloys."

 

For the first month, Izuku’s life became a rigorous, calculated loop. He woke at 4:00 AM, ingested a highly calibrated, nutrient-dense protein shake, and spent three hours at Dagobah Beach ripping apart machinery with his bare hands and tools. He learned leverage—how to crack a rusted car door off its hinges not by pulling wildly, but by identifying the stress point in the metal and applying torque. His body adapted rapidly. The baby fat of his cheeks melted away, replaced by sharp lines. Underneath his oversized shirts, his muscles became dense, tightly coiled springs, built for endurance and explosive speed rather than show.

 

But the true awakening happened in the afternoons, inside U.A.’s Development Studio.

 

The U.A. workshop was a paradise of 3D printers, laser cutters, CNC machines, and soldering stations. The resident teacher, the Pro Hero Power Loader, had been warned by Nezu to give Izuku a wide berth.

 

On his third day in the lab, Izuku was bent over a workbench, meticulously welding a kinetic-dampening spring to a custom-molded carbon-fiber forearm brace, when the door to the lab was kicked open with explosive force.

 

"MAKE WAY FOR MY BABIES!" a voice shrieked.

 

A girl with wild, thick pink hair and crosshair-like irises burst into the room, carrying what looked like a jetpack hastily strapped to a lawnmower engine. She dumped the contraption onto a nearby desk, entirely ignoring Izuku, and began violently wrenching a bolt with a spanner.

 

Izuku stopped his welding. He flipped up his visor and stared at the girl.

 

Mei Hatsume. First-year support course applicant. Given her presence in the lab before the school year begins, she likely received early access due to exceptional talent or sheer persistence. The device she is working on is highly unstable. The fuel-to-air mixture in that combustion chamber is off by a lethal margin.

 

"Excuse me," Izuku said clearly, his voice cutting through the clanging of her wrench. "If you ignite that primary thruster, the backdraft will incinerate the secondary fuel line and blow a hole in the ceiling."

 

Mei froze. She slowly turned her head, her crosshair eyes zeroing in on Izuku.

 

"Who the heck are you?" she demanded, marching over to his workstation. She leaned in uncomfortably close, inspecting him. "And what do you know about my babies?"

 

"I know that your thrust vectoring is misaligned," Izuku replied smoothly, not stepping back. He picked up a pencil and rapidly sketched an equation on a scrap of paper. "You are using a linear propulsion model for a multi-axis stabilizer. If you adjust the nozzle aperture by zero-point-four centimeters and reroute the exhaust through a thermal sink, you’ll increase fuel efficiency by thirty percent and avoid blowing us both up."

 

Mei stared at the math. Her eyes widened. The gears in her head clicked into place, perfectly meshing with Izuku’s logic.

 

"A thermal sink..." Mei whispered, her grin stretching from ear to ear. "Of course! The heat dispersal will prevent vapor lock! You... you're a genius!"

 

"I am mathematically proficient," Izuku corrected.

 

Mei slammed her hands on his desk, her eyes practically sparkling with madness. "I like you! You speak my language! What are you building? Show me! Show me!"

 

She grabbed Izuku’s half-finished forearm brace. Izuku didn't snatch it back; he simply explained.

 

"It's a kinetic-redirection exosuit brace," Izuku said, speaking at his usual, rapid-fire pace. "I am Quirkless. Therefore, engaging in physical combat with Quirk-enhanced individuals is statistically disadvantageous. The human skeleton can only withstand so much blunt force trauma. This brace is laced with piezoelectric crystals and micro-hydraulics. When a physical impact hits the outer shell, the crystals absorb the kinetic energy, convert it into a mild electrical charge, and use it to power the hydraulic pistons for a counter-strike."

 

Mei gasped, her hands shaking with excitement. "You're recycling the enemy's punch to power your own punch! That's... that's beautifully efficient! But your servos are too heavy! If you use a titanium-mesh weave instead of solid plates, you can cut the weight by half and increase arm velocity!"

 

"I don't have access to military-grade titanium mesh," Izuku noted.

 

"I DO!" Mei shrieked, sprinting over to a locked cabinet. She picked the lock with a hairpin in three seconds flat and pulled out a roll of shimmering metal fabric. "Let's make a baby!"

 

From that day forward, the Development Studio became a hazard zone for anyone but them. Izuku and Mei formed an intellectual symbiosis that terrified Power Loader. They communicated in a rapid, overlapping stream of technical jargon, physics equations, and manic laughter. Mei had the sheer, unhinged mechanical creativity, while Izuku had the flawless mathematical precision and tactical foresight to make her designs functional and deadly.

 

Over the next few months, the exosuit was born.

 

Izuku didn't want an Iron Man suit. Full armor was bulky, restricted peripheral movement, and relied too heavily on battery life. If a battery died in a full suit, it became a coffin.

 

Instead, he designed an under-suit. It was a sleek, matte-black, compression-fit bodysuit interwoven with carbon nanotubes and Kevlar. Over this, he strapped modular, low-profile mechanical braces to his shins, knees, forearms, and spine. The braces didn't move for him; they augmented his natural movements. They allowed him to jump three times higher, punch with the force of a hydraulic press, and absorb impacts that would shatter normal bones.

 

He also developed his arsenal.

 

"EMP grenades are standard," Izuku muttered to Mei one afternoon as he carefully filled a small spherical casing. "But villains with mechanical Quirks or support gear often have electromagnetic shielding. We need a physical disruptor."

 

"What about a localized sonic dampener?" Mei suggested, soldering a circuit board. "A frequency high enough to shatter glass but focused inward."

 

"Good, but let's go further," Izuku said, his eyes gleaming. "A flash-bang that doesn't just emit light, but uses a rapidly expanding polyurethane foam. A restraint and a distraction simultaneously."

 

They built it all. Grappling hooks concealed in his wrist gauntlets. Smoke pellets laced with a mild, non-lethal neurotoxin that induced vertigo. Earpieces that constantly scanned local police and hero radio frequencies.

 

Izuku was building a utility belt, but his greatest weapon remained his mind.

 

 

 

While his afternoons were spent engineering, his evenings belonged to Aizawa Shota.

 

The U.A. training gym was a massive, cavernous room with reinforced concrete walls and heavy tumbling mats. It was here that Izuku learned how to bleed.

 

"You're dead," Aizawa said flatly.

 

Izuku was currently pinned face-down on the mat, Aizawa’s knee pressed firmly between his shoulder blades, holding his arm in an agonizing joint lock.

 

"Your reaction time was sufficient, but your center of gravity was too high," Aizawa lectured, releasing the hold and stepping back. "You tried to block my kick. Never block a strike from a stronger opponent, Midoriya. Evade, redirect, or preempt."

 

Izuku pushed himself off the mat, wiping a trail of sweat from his forehead. His breathing was heavy, but his eyes were bright, analyzing every micro-movement Aizawa made.

 

Aizawa was a brutal teacher, but an effective one. He didn't teach Izuku flashy martial arts. There were no high kicks or complex katas. Aizawa taught him the ugly, vicious reality of underground combat: Krav Maga, Brazilian Jiu-Jitsu, and weaponized biomechanics.

 

"An opponent with a strength Quirk relies on momentum and intimidation," Aizawa explained, pacing around Izuku in a slow circle. "They throw wide, heavy punches because they expect their power to end the fight instantly. Your job is to make them miss. A punch that misses throws their entire skeletal structure off balance. The human body, no matter how mutated, is bound by physics. Joints only bend one way. Eyes, throats, groins, and knees do not have muscles to protect them."

 

Izuku nodded, settling into a low, relaxed stance. He kept his hands open, rather than in fists. Open hands allowed for grappling, deflecting, and faster strikes.

 

"Again," Aizawa ordered, rushing forward.

 

Aizawa threw a rapid jab, followed by a sweeping low kick.

 

Time seemed to slow down for Izuku. His hyper-active brain dissected Aizawa’s assault.

 

Shoulder twitch. Pivot on the back foot. The jab is a feint to obscure my vision; the true threat is the low kick targeting my left peroneal nerve to disable my leg.

 

Instead of backing away, Izuku stepped into the attack. He slipped inside Aizawa’s guard, entirely ignoring the feint punch. As Aizawa’s leg swung around, Izuku dropped his weight, catching Aizawa’s thigh with his elbow, targeting the sciatic nerve bundle.

 

Aizawa grunted in surprise as his leg went momentarily numb.

 

Instantly, Izuku capitalized. He didn't try to punch Aizawa in the face. Instead, he grabbed Aizawa’s extended wrist, spun, and used Aizawa’s own forward momentum to execute a flawless shoulder throw.

 

Aizawa hit the mat with a heavy thud.

 

Before the hero could recover, Izuku dropped his knee heavily onto Aizawa’s bicep, pinning the arm, and positioned his fingers hovering an inch over Aizawa’s trachea.

 

Silence filled the gym.

 

Izuku’s chest heaved. He didn't blink. He waited for Aizawa’s response.

 

Aizawa looked up at the ceiling, then shifted his gaze to the boy pinning him. A slow, highly uncharacteristic smirk pulled at the corner of the hero's mouth.

 

"Not bad, problem child. You used my mass against me." Aizawa tapped the mat twice in submission.

 

Izuku immediately released him and stepped back, offering a hand to help his teacher up. Aizawa ignored the hand, rolling to his feet with feline grace.

 

"Your physical technique is catching up to your brain," Aizawa noted, rubbing his shoulder. "But you're still relying too much on clean technique. In a real fight against villains, there are no clean techniques. They will bite, scratch, and use environmental hazards. You need to be dirtier."

 

"Understood, Sensei," Izuku said, adjusting his sweat-soaked shirt. "I have begun integrating environmental variables into my mental simulations. Calculating ricochet angles for debris, optimizing spatial awareness to keep enemies between myself and light sources to obscure my silhouette."

 

Aizawa stared at him. Sometimes, teaching Izuku was like trying to teach a supercomputer how to play chess; you only showed it the rules once, and then it beat you in ten moves.

 

"Tomorrow, we spar with weapons," Aizawa said, grabbing his water bottle. "You bring those gadgets you've been building with Hatsume. I want to see if you can integrate technology with martial arts without relying on the tech as a crutch."

 

"I look forward to it."

 

 

 

Month Ten. The Final Week.

 

The Nezu Protocol had reached its culmination.

 

Izuku stood in the center of U.A.’s Ground Beta, a massive, simulated cityscape used for hero training. He was no longer the soft, anxious boy who had cowered under Katsuki Bakugo’s explosions. He was a weapon, forged by logic, engineering, and relentless discipline.

 

He wore the finalized version of his tactical suit. The base layer was a dark, charcoal-grey Nomex fabric, fire-resistant and highly flexible. Over it, the matte-black, titanium-mesh exosuit braces gripped his limbs. A utility belt rested on his hips, lined with compact, specialized cartridges. His boots had silent, shock-absorbing soles. He looked like a shadow cast in metal.

 

Watching him from the observation room were Principal Nezu and Aizawa.

 

"The parameters of this final test are simple, Izuku," Nezu’s voice crackled through a concealed earpiece in Izuku’s ear. "Aizawa has placed a simulated payload—a briefcase—somewhere within a four-block radius of your position. You have fifteen minutes to locate and secure it. However, Aizawa is currently in the city. He is actively hunting you. If he captures you, or if the time runs out, you fail."

 

"Understood," Izuku replied, his voice calm and entirely devoid of adrenaline-induced shake.

 

"Begin."

 

Izuku didn't run. Running created noise and wasted kinetic energy. He immediately moved to the nearest alleyway, clinging to the shadows. He tapped a button on his wrist gauntlet.

 

A holographic projection of the city grid appeared over his forearm.

 

Analysis, Izuku thought, his eyes darting across the map. Aizawa knows I am fast and have vertical mobility. He will not hide the briefcase in an open area; he will place it in a chokepoint to force an encounter. The most logical chokepoints in this sector are the central bank vault and the subway terminal.

 

Izuku tapped his earpiece, activating a localized sonar-ping—a device he and Mei had reverse-engineered from bat echolocation. He sent out a high-frequency pulse. It bounced off the buildings, returning data to his wrist-pad.

 

Movement detected. Third floor, building adjacent to the bank. Fast, erratic. Aizawa is using his capture weapon to traverse the rooftops.

 

Izuku smiled slightly. He didn't head for the bank. He headed directly for the building Aizawa was on.

 

Using his exosuit’s leg braces, Izuku crouched low, compressed the hydraulic pistons, and launched himself vertically. He cleared twenty feet in a single bound, grabbing the fire escape of an adjacent building. He climbed silently, moving like a spider, until he reached the rooftop overlooking Aizawa’s position.

 

He saw his teacher crouched near a gargoyle, peering down into the streets, waiting for Izuku to make a mistake. The briefcase was sitting right next to him.

 

Direct confrontation with Eraserhead is mathematically unsound. His capture weapon has a range of fifteen meters. I need to disable his sensory input and neutralize his weapon simultaneously.

 

Izuku reached into his belt and pulled out two spheres. One was the polyurethane flash-bang. The other was a specialized magnetic-pulse emitter.

 

He didn't throw them directly at Aizawa. Aizawa had incredible reflexes and would simply dodge.

 

Instead, Izuku calculated the wind speed, the angle of the adjacent billboard, and the tensile strength of the gargoyle Aizawa was leaning against. He threw the magnetic pulse emitter at the billboard. It adhered to the metal surface with a loud CLANG.

 

Aizawa whipped around, his scarf flaring out, his red eyes glowing as he activated his Quirk. But there was no one there. And his Quirk didn't work on technology.

 

The emitter detonated, releasing a powerful, localized magnetic field.

 

Aizawa’s capture weapon—woven with steel wire—suddenly violently yanked toward the billboard, pinning Aizawa’s scarf, and by extension his upper body, to the metal structure.

 

"What the—" Aizawa grunted, struggling against the magnetic pull.

 

A fraction of a second later, Izuku dropped from above, landing softly behind Aizawa. He threw the flash-bang directly at Aizawa’s feet.

 

BANG.

 

A blinding flash of light was accompanied by a rapid explosion of thick, expanding, fast-hardening foam. The foam engulfed Aizawa’s boots, gluing him firmly to the concrete roof.

 

Izuku casually walked past his temporarily blinded, pinned, and incredibly irritated teacher. He picked up the briefcase.

 

"Test concluded," Izuku said aloud, tapping his earpiece. "Time elapsed: three minutes and forty-two seconds."

 

Aizawa blinked away the flash-blindness, looking down at his trapped feet and his magnetically pinned scarf. He sighed heavily, a mixture of profound exhaustion and undeniable pride washing over him.

 

"You're a menace, kid," Aizawa muttered.

 

Up in the observation room, Nezu was cackling with glee, kicking his small feet in the air. "Oh, this is going to be a spectacular year! The Hero Commission won't know what hit them!"

 

 

 

The Morning of the U.A. Entrance Exam.

 

Izuku Midoriya stood before the massive, towering gates of U.A. High School. The morning sun reflected off the pristine glass architecture of the main building. All around him, thousands of hopeful teenagers swarmed the entrance, chattering nervously, stretching, and subtly showing off their Quirks.

 

Izuku felt an absolute, profound sense of calm.

 

He wasn't wearing a school uniform. He wore civilian clothes over his compression suit, his heavy boots making soft thuds against the pavement. His exosuit braces were currently retracted into their low-profile mode, hidden beneath his jacket, but the weight of them was a comforting anchor. His backpack contained his customized support gear, pre-approved by Nezu under a special administrative loophole Izuku had personally drafted and submitted.

 

"Stupid Deku."

 

The abrasive, gravelly voice came from behind him.

 

Izuku didn't flinch. He turned slowly.

 

Katsuki Bakugo stomped toward him, hands shoved deep into his pockets, glaring with absolute venom. Katsuki looked at Izuku, expecting the nervous, stuttering mess he had bullied for a decade.

 

But the boy standing before him was alien. Izuku’s posture was immaculate. His jawline was sharp. His eyes, once wide and fearful, were now narrowed, cold, and assessing. He looked at Katsuki not as a threat, but as a solved equation.

 

"Get out of my way," Katsuki snarled, stepping into Izuku’s personal space, trying to force him to back down. "I don't know what kind of joke you're playing, showing up here Quirkless, but this is the big leagues. You're gonna get yourself killed. Go home."

 

Izuku didn't move an inch. He looked Katsuki dead in the eye.

 

"Your heart rate is elevated, Katsuki," Izuku said quietly, his rapid-fire voice dropping to a low, dangerous hum. "You are breathing from your upper chest, a clear indicator of performance anxiety. You are projecting your insecurity onto me to stabilize your own ego before a high-stakes exam."

 

Katsuki’s breath hitched. His palms sparked involuntarily. "You little—"

 

"I am not in your way, Katsuki," Izuku interrupted calmly, stepping aside with fluid grace. He gestured toward the gates. "I am simply on a different path entirely. Try not to break your wrists from the recoil of your explosions today. Your form has always been sloppy."

 

Izuku turned his back on Bakugo and walked through the gates of U.A., blending into the crowd of aspiring heroes.

 

He didn't need luck. Luck was a variable for those who hadn't done the math.

 

Izuku Midoriya had done the math. And the odds were entirely in his favor.

 

The auditorium of U.A. High School was a cavernous, amphitheatrical space designed to comfortably seat thousands of applicants. The lighting was deliberately kept low, drawing all attention to the brightly lit stage where the Voice Hero, Present Mic, stood behind a podium.

 

Izuku Midoriya sat in the middle row of Sector B, his posture perfectly straight, his eyes fixed on the stage. To his right sat Katsuki Bakugo, who was practically vibrating with aggressive anticipation. To his left was an empty seat.

 

"WELCOME TO TODAY'S LIVE PERFORMANCE!" Present Mic roared, his Quirk-amplified voice echoing off the acoustic paneling of the ceiling. "EVERYBODY SAY 'HEY'!"

 

The auditorium was met with dead, uncomfortable silence.

 

Psychological baseline testing, Izuku noted internally, his fingers resting casually on the customized wrist-pad concealed beneath his jacket sleeve. He is deliberately utilizing a high-energy, informal persona to gauge the crowd's adaptability to sudden tonal shifts. The lack of response indicates a high level of collective anxiety and rigid adherence to perceived testing decorum.

 

"WELL, THAT'S COOL, MY EXAMINEE LISTENERS!" Present Mic continued, completely unfazed by the silence. "I'M HERE TO PRESENT THE GUIDELINES OF YOUR PRACTICAL! ARE YOU READY?!"

 

Silence again. Izuku didn't bother responding. He had more pressing matters to attend to.

 

Under the cover of the darkened auditorium, Izuku slipped his right hand into his jacket and activated his wrist-pad. A tiny, faint holographic interface flickered to life, visible only from his direct angle. While Present Mic began explaining the point system—villain bots worth one, two, and three points—Izuku’s fingers flew across the haptic keyboard.

 

U.A.’s cybersecurity is formidable, Izuku thought, his eyes tracking the code scrolling across his miniature screen. A standard brute-force attack would trigger an immediate lockdown and likely trace back to my IP address, resulting in disqualification. However, an institution this large inevitably suffers from compartmentalization errors. The Hero Course servers are locked down, but the Support Course development servers? They require constant external access for material sourcing.

 

Izuku pinged a decoy signal to the school’s front-end admissions page, deliberately triggering a low-level firewall response. While the automated security protocols were distracted closing that minor breach, Izuku routed a secondary, encrypted signal through the school's HVAC maintenance subnet. It was an old, unpatched backdoor.

 

Access granted.

 

"You will be experiencing ten minutes of simulated urban combat!" Present Mic yelled, striking a pose. "You can bring whatever you want with you! After this presentation, you'll head to your specified battle centers, okay?!"

 

Downloading schematic files... Izuku navigated the Support Course database. Power Loader is meticulous, but Hatsume mentioned last week that they recently archived the previous generation of test-robot blueprints to clear server space. Archival servers rarely possess the same active encryption as primary servers.

 

File located: 'Project_Tartarus_Urban_Bots_v4.2'. Downloading.

 

"Excuse me! May I ask a question?"

 

A tall, broad-shouldered applicant with glasses shot out of his seat several rows ahead of Izuku. His arm was raised rigidly in the air.

 

"Okay!" Present Mic pointed at him. A spotlight immediately snapped onto the boy.

 

"On the handout, there are clearly four types of villains!" the boy barked, his voice projecting across the room. "If this is a misprint, then U.A., the most prominent school in Japan, should be ashamed of that foolish mistake! We examinees are here in this place because we wish to be molded into exemplary heroes!"

 

Izuku barely looked up, though he recognized the boy’s engine-like calves. Tenya Iida. Family has a long lineage of speed-based heroes. Highly rigid psychological profile. Adheres strictly to rules and struggles with ambiguity.

 

"In addition," Iida turned sharply, pointing directly at Izuku. "You, with the unkempt hair! You've been looking down and muttering to yourself, and your jacket is emitting a faint blue light! It's distracting! If you're here on a pleasure trip, then you should leave immediately!"

 

The auditorium shifted its collective gaze toward Izuku. Katsuki Bakugo sneered, clearly waiting for Izuku to stutter, panic, and make a fool of himself.

 

Instead, Izuku calmly closed his jacket, extinguishing the light of the wrist-pad. The download was already complete. He stood up slowly, meeting Iida’s intense glare with a gaze so flat and clinical it made the taller boy falter for a fraction of a second.

 

"My apologies for the distraction," Izuku said, his voice carrying perfectly without a microphone, the cadence rapid and precise. "However, if you review page four, paragraph three of your handout, you will find a detailed addendum stating that personal support gear is permitted pending prior administrative approval, which I possess. Furthermore, if you had allowed the proctor to finish his presentation instead of interrupting him to performatively demonstrate your own diligence, he likely would have explained the fourth villain type."

 

Izuku didn't sit down. He kept his eyes locked on Iida. "A hero must possess situational awareness, applicant. Jumping to conclusions based on incomplete data in the field will get civilians killed. I suggest you hold your questions until the briefing is concluded."

 

Izuku sat back down.

 

The auditorium was dead silent. Iida stood frozen, his mouth slightly open, thoroughly dismantled by the cold, flawless logic. He flushed a deep red, bowed stiffly, and muttered, "I... I apologize. You are entirely correct." He sat down quickly.

 

Katsuki stared at Izuku, his hands twitching, smoke curling from his palms. "Deku... what the hell was that?"

 

"Efficiency, Katsuki," Izuku whispered back, not looking at him.

 

On stage, Present Mic let out a loud whistle. "ALRIGHT, ALRIGHT! EXAMINEE NUMBER 7111 HAS A GREAT POINT! Let's get to the fourth villain! The Zero Pointer!"

 

Present Mic explained the massive obstacle, describing it as an unkillable hazard meant to be avoided. Izuku processed the information, comparing it to the blueprints now sitting comfortably in his wrist-pad's local storage.

 

The Zero Pointer. An architectural hazard rather than an opponent. The psychological test is obvious: it assesses an applicant's ability to prioritize survival and retreat over ego-driven combat.

 

"THAT'S ALL FROM ME!" Mic shouted. "PLUS ULTRA!"

 

 

 

Battle Center B.

 

The mock city was a staggering feat of engineering. It stretched for miles, a perfect replica of a dense urban environment, complete with high-rise buildings, asphalt roads, and traffic lights.

 

Izuku stood near the back of the massive crowd of applicants gathered before the towering steel gates. While others were stretching their hamstrings, hyping themselves up, or activating their Quirks to test their limits, Izuku was perfectly still.

 

He had stripped off his outer jacket, revealing his matte-black compression suit. He tapped the sides of his thighs, activating his leg braces. A soft, barely audible mechanical whir hummed to life as the micro-hydraulics engaged. He adjusted his utility belt, making sure his custom cartridges were properly seated.

 

A few feet away, he noticed a girl with a round face and short brown hair. She was taking deep breaths, her hands pressed together. Ochako Uraraka. Quirk: Zero Gravity. Emit-type. Requires physical contact via the pads on her fingertips. Highly versatile, but susceptible to nausea if overused due to inner-ear equilibrium disruption.

 

Izuku adjusted the dial on his wrist-pad, bringing up the blueprints he had downloaded. He scanned the internal anatomy of the one, two, and three-point robots.

 

Armor plating: standard U.A. steel alloy. Resistant to blunt force. Weak points: optical sensory array located in the central 'eye', hydraulic fluid lines at the knee joints, and an exposed exhaust port at the base of the cervical spine. Strategy: Do not engage in kinetic contests. Blind, cripple, and disable.

 

"START!"

 

Present Mic’s voice echoed from a loudspeaker high above the gates.

 

The massive doors began to swing open. The crowd of applicants hesitated, waiting for a buzzer, a countdown, or an official starting gun.

 

Izuku didn't wait.

 

The moment there was a gap wide enough for a human body, the micro-hydraulics in Izuku’s legs fired. He launched himself forward, a blur of black fabric and dark metal. He was inside the mock city before the doors had even fully opened.

 

"What are you waiting for?!" Mic yelled from the speakers. "There are no countdowns in real battles! RUN, RUN, RUN!"

 

The crowd panicked and surged forward. By the time they entered the city, Izuku was already two blocks deep.

 

A Three-Pointer rolled out from an alleyway, its treads grinding against the asphalt. Its optical sensor glowed red, locking onto Izuku. Missiles popped from its shoulders.

 

"Target acquired," the machine's robotic voice droned.

 

Izuku didn't break his stride. He reached into his belt and pulled out a small, metallic cylinder. As the robot raised its arm cannons, Izuku threw the cylinder directly at the ground in front of the robot.

 

The cylinder detonated, but not with an explosion. It released a concentrated burst of highly reflective, metallic chaff into the air, creating a shimmering cloud of micro-mirrors.

 

The robot’s optical array—which relied on lasers to judge distance and target lock—was instantly blinded by the reflection of its own sensors. The machine froze, its internal processor encountering a fatal targeting error.

 

Izuku didn't stop to admire his work. As he sprinted past the blind, immobile machine, he drew a hardened, high-carbon steel baton from his thigh holster. With a fluid, practiced flick of his wrist, he drove the baton directly into the hydraulic line exposed at the back of the robot's knee joint.

 

Sshhhhk!

 

Pressurized hydraulic fluid sprayed violently onto the pavement. The Three-Pointer collapsed forward, its right leg entirely useless, crashing into a brick wall.

 

Three points. Time elapsed: forty-five seconds.

 

Izuku turned a corner. A group of five robots—three One-Pointers and two Two-Pointers—were blocking the main intersection.

 

Direct engagement with a group will drain stamina and risk exosuit damage. Require an area-of-effect solution.

 

Izuku scaled a nearby lamppost using his arm braces, leaping from the top to land on a fire escape. He looked down at the cluster of robots below. He pulled out a slightly larger, spherical device from his belt.

 

He tapped a sequence into his wrist-pad. He was accessing the unencrypted radio frequency that the robots used to communicate their coordinates to each other—a frequency he had found in the downloaded blueprints.

 

He didn't need to hack them entirely; he just needed to introduce a conflicting data packet.

 

Izuku dropped the sphere into the center of the robot cluster. The sphere emitted a piercing, localized electromagnetic pulse, perfectly tuned to scramble the IFF (Identify Friend/Foe) transponders inside the machines.

 

The robots' glowing red eyes flickered to a confused, erratic yellow. Suddenly, the central Two-Pointer’s sensors registered the One-Pointers beside it not as allies, but as enemy applicants.

 

The Two-Pointer swung its massive metal fist, decapitating the One-Pointer next to it. The remaining robots immediately retaliated, turning their weapons on each other in a storm of friendly fire.

 

Izuku watched from the fire escape as the machines tore each other to pieces. When the dust settled, all five were smoking ruins.

 

Seven points. Total: ten points. Time elapsed: one minute, twenty seconds.

 

He continued his run. He was a ghost on the battlefield. He didn't roar, he didn't smash buildings, and he didn't leave craters. He moved with absolute, terrifying efficiency.

 

He used a specialized laser-pointer attached to his wrist to blind optical sensors from afar, causing robots to crash into walls. He used high-tensile tripwires to snag the treads of the heavy Three-Pointers, flipping them onto their backs like helpless turtles. When forced into close quarters, he used Aizawa’s martial arts, stepping inside the robots' guard and utilizing leverage to snap their joints backward.

 

At the six-minute mark, Izuku had accumulated fifty-four points. He was barely out of breath.

 

He vaulted over the chassis of a downed Two-Pointer, landing lightly on the pavement. He was about to proceed down the central avenue when he noticed a male applicant—a kid with a minor physical mutation that gave him scales—tripping over a piece of debris.

 

A Three-Pointer loomed over the scaled boy, raising its massive arm to crush him.

 

Izuku evaluated the situation. The exam parameters strictly grade villain destruction. There is no stated point value for saving a fellow applicant. However...

 

Izuku remembered Nezu’s words in the living room. Hero society is stagnant... we are churning out generations of hammers.

 

U.A. is a hero academy, Izuku deduced rapidly. A heroic institution cannot fundamentally grade its applicants solely on their capacity for violence. It contradicts the foundational ethics of heroics. There must be a hidden metric. Rescue points. It is the only logical conclusion.

 

Izuku didn't hesitate. He activated his leg hydraulics to maximum output, the servos whining loudly. He cleared the thirty-foot distance in a single leap. He didn't attack the robot; he tackled the scaled boy, rolling them both out of the way a fraction of a second before the Three-Pointer’s fist shattered the asphalt where the boy had been sitting.

 

"Move," Izuku commanded the boy, pulling him to his feet. "Your left ankle is sprained. Limp toward the periphery of the zone; the villain density is lower there."

 

"T-thank you!" the boy stammered, hobbling away.

 

Izuku spun around, tossed a thermite pellet directly into the Three-Pointer's exposed exhaust vent, and walked away as the machine’s internal wiring melted into slag.

 

 

 

The Observation Room.

 

High above the mock cities, situated in a darkened, multi-monitor control room, the faculty of U.A. High watched the exam unfold.

 

Pro Heroes Midnight, Snipe, Vlad King, and Cementoss stood in a semi-circle around a massive array of screens. Aizawa Shota stood in the corner, his arms crossed, his face buried in his capture scarf. Sitting at the central console, sipping tea from a delicate porcelain cup, was Principal Nezu.

 

"This year's crop looks promising," Midnight commented, twirling her whip. "Look at the explosive kid in Center A. He's got remarkable combat instincts. He's racking up points purely through raw power."

 

"The gravity girl is doing well, too," Snipe noted, pointing to another screen. "Disabling them by removing their friction. Smart."

 

"But," Vlad King leaned forward, his massive brow furrowed. He pointed a thick finger at the central monitor, which was currently locked onto Battle Center B. "What the hell is that kid doing?"

 

All eyes turned to the monitor.

 

They watched footage of Izuku Midoriya. He wasn't fighting. He was casually walking down an alleyway. A robot rounded the corner, and before it could even raise its arms, Izuku casually tossed a small disk that adhered to its chest. The disk emitted a localized sonic frequency that shattered the glass shielding the robot's motherboard, causing it to short-circuit instantly. Izuku kept walking without breaking stride.

 

"Is that a techno-path Quirk?" Snipe asked, adjusting his mask. "Or maybe an EMP emission?"

 

"He has no Quirk," Aizawa said flatly from the corner.

 

The room fell silent. All the teachers turned to look at the underground hero.

 

"Excuse me, Eraser?" Midnight asked, blinking. "Did you just say he's Quirkless? That's impossible. Look at how he moves! He just jumped twenty feet in the air to avoid that missile!"

 

"He's wearing a custom-built, hydraulic exosuit beneath his clothes," Aizawa explained, a faint hint of smugness in his tired voice. "Everything he's using—the EMPs, the chaff grenades, the sonic emitters, the thermite—he built it himself. And he's using it perfectly. He's not fighting the robots. He's solving them."

 

"He's treating a chaotic battlefield like a controlled laboratory environment," Vlad King muttered, clearly unsettled. "He has sixty points already. And he just earned forty rescue points for saving that scaled kid. He's dominating the leaderboard."

 

Nezu took a slow, deliberate sip of his tea. His beady black eyes gleamed with terrifying amusement.

 

"Pro Heroes often make the mistake of believing that power equates to superiority," Nezu squeaked, setting his cup down. "But power is merely a tool. Midoriya Izuku is demonstrating what happens when a truly exceptional intellect is given the proper resources. He has mapped the robots' behavioral algorithms, identified their structural weak points, and is executing a flawless, energy-efficient tactical sweep."

 

Nezu reached out and hovered his paw over a large red button on the console.

 

"However," the principal smiled, his teeth flashing in the dim light. "A true hero must be able to adapt when the equation is suddenly altered. Let's see how our young architect handles a variable he cannot easily dismantle."

 

Nezu slammed his paw down on the button.

 

 

 

Battle Center B.

 

Two minutes remaining, Izuku noted, checking the internal clock on his HUD. Score: Seventy-two villain points. Estimated rescue points: Unknown, but theoretically sufficient. Physical status: Exosuit battery at forty percent. Mild lactic acid buildup in the calves. Optimal strategy: Evade remaining targets and preserve stamina until the timer expires.

 

Suddenly, the ground trembled.

 

It wasn't a minor tremor. It was a violent, seismic shockwave that threw several applicants to the ground. The windows of the mock buildings shattered in unison, cascading rain of safety glass onto the streets.

 

A shadow fell over the sector.

 

Izuku looked up. At the far end of the central avenue, the buildings were literally being pushed apart. A colossal hand, easily the size of a city block, gripped the top of a skyscraper and crushed it into dust.

 

The Zero Pointer.

 

It was a nightmare of steel and hydraulics, towering over a hundred meters tall. It moved on massive, tank-like treads that tore the asphalt to shreds. Its single, glowing red eye was the size of a billboard.

 

"LESS THAN TWO MINUTES LEFT!" Present Mic’s voice blared.

 

Panic erupted. The applicants, who had been bravely fighting the smaller robots moments before, broke instantly. They turned and sprinted away in sheer, unadulterated terror.

 

"Run!"

 

"That thing is massive! We can't fight that!"

 

Izuku stood still in the middle of the street. The wind generated by the robot's movement whipped his hair around his face. He looked at the mechanical titan.

 

Fight or flight response activated across the populace. Highly logical. The machine is designed to induce the sublime terror of overwhelming scale. It has no point value. Engaging it is a tactical error.

 

Izuku turned to join the retreat. He had no reason to stay.

 

But as he turned, his enhanced auditory sensors picked up a faint, strained sound cutting through the grinding of metal and the screams of the applicants.

 

"Ow... my leg..."

 

Izuku stopped. He turned his head.

 

About sixty meters away, directly in the path of the advancing Zero Pointer, was Ochako Uraraka. She had tripped during the panic, and a massive slab of concrete from a destroyed building had pinned her leg to the ground. She was struggling, her face pale, trying to use her Quirk on the rubble, but the sheer mass of it was too much for her currently exhausted state.

 

The Zero Pointer’s massive tread was rolling directly toward her. She had perhaps thirty seconds before she was crushed.

 

Izuku looked at the retreating applicants. Iida was running, though he looked back, his face torn with indecision. Others were simply fleeing blind. No one was going to reach her in time.

 

Izuku exhaled slowly. His heart rate, which had been perfectly steady the entire exam, spiked.

 

Analyzing variables, his brain fired into hyper-drive, perceiving time as a sluggish crawl. Target: Zero Pointer. Weight: Estimated 5,000 metric tons. Height: 120 meters. My physical strength is entirely negligible. My thermite pellets lack the volume to breach its armor. My EMPs do not have the range to encompass its chassis. I cannot destroy it with brute force.

 

He looked at the robot’s structure. He didn't see a monster; he saw a physics equation waiting to be balanced.

 

Look at its design. It is humanoid in the upper half, but rests on a tank-tread base. It is incredibly top-heavy. Its center of gravity is precariously high, heavily reliant on the gyroscopic stabilizers in its central torso. Its treads are designed for forward kinetic momentum, but lack lateral stability.

 

Izuku looked around the environment. The mock city was heavily damaged. To the right of the Zero Pointer stood a half-destroyed, ten-story building. Its structural integrity was already severely compromised by the robot's entrance.

 

An intricate, multi-step blueprint materialized in Izuku’s mind. It was insane. It required flawless timing, precise execution, and a high probability of severe injury if he failed.

 

Izuku tapped his wrist-pad, overriding the safety limiters on his exosuit.

 

Warning: Hydraulic pressure exceeding safe parameters. Muscle and bone damage imminent, the suit's automated voice whispered in his ear.

 

"Override," Izuku muttered.

 

He didn't run away. He sprinted directly toward the colossal machine.

 

"What is he doing?!" an applicant screamed from behind him. "He's gonna die!"

 

Izuku ignored them. His boots slammed against the pavement, his mechanical braces whining as they pushed his body to superhuman speeds. He closed the distance to Uraraka in seconds.

 

"Deku?!" Uraraka gasped as Izuku slid to a halt beside her. "What are you—"

 

"Do not speak. Conserve oxygen," Izuku ordered rapidly. He didn't try to lift the rubble. It was too heavy, even with the suit. Instead, he reached into his belt and pulled out a high-density expanding foam grenade—the same kind he used on Aizawa. He shoved it into the gap between the concrete slab and Uraraka’s leg and detonated it.

 

The foam expanded violently, acting as a pneumatic jack, lifting the concrete just enough to relieve the pressure on her limb.

 

"Crawl out!" Izuku ordered. Uraraka scrambled backward, freeing her bruised leg.

 

The Zero Pointer was now only twenty meters away. The shadow of its massive fist eclipsed the sun as it began to swing down toward them.

 

"Run toward the exit!" Izuku yelled at her.

 

"But you—!"

 

"RUN!"

 

Izuku didn't wait to see if she obeyed. He activated the grappling hook concealed in his right wrist gauntlet. He fired it at the partially destroyed, ten-story building to his right. The titanium grapple bit deep into the concrete.

 

The servos in his arm screamed as the winch retracted, violently pulling Izuku off the ground and launching him through the air. He soared over the Zero Pointer’s descending fist, landing hard on the fourth-floor balcony of the ruined building.

 

He didn't stop. He scrambled inside the building, his brain calculating load-bearing walls and stress distribution.

 

The building is leaning left. The main support pillar on the ground floor is cracked. If I destroy that pillar, the building falls outward.

 

Izuku dropped down the ruined stairwell, landing on the ground floor. The massive central pillar stood before him. The Zero Pointer was now directly adjacent to the building, its massive treads shaking the foundation.

 

Izuku pulled out his three remaining thermite charges. He didn't throw them. He rushed to the pillar and slapped all three directly onto the structural faults in the concrete.

 

He set the timers for five seconds.

 

He sprinted out the back exit of the building just as the charges detonated.

 

BOOM!

 

The thermite burned at 4,000 degrees Fahrenheit, melting the steel rebar and vaporizing the concrete. The pillar ceased to exist.

 

Physics took over.

 

Without its central support, the ten-story building groaned violently. Millions of tons of concrete, steel, and glass shifted. The building collapsed laterally, falling directly outward and slamming into the right side of the Zero Pointer's torso.

 

The impact was deafening. The kinetic force of a collapsing building was immense, but it wasn't enough to destroy the robot.

 

But Izuku hadn't intended to destroy it. He intended to unbalance it.

 

The massive robot was struck hard on its right side. To compensate and maintain its center of gravity, its internal gyroscopes immediately forced the machine to shift its massive weight to its left tread.

 

Now, Izuku thought, standing in the dust cloud. All of its weight is concentrated on the left drive sprocket.

 

Izuku raised his left arm. He flipped a hidden switch on his gauntlet. This wasn't a gadget he had built with Mei Hatsume. This was a direct application of the materials he had scavenged from the beach.

 

It was a single-use, compressed pneumatic cannon, loaded with a solid rod of depleted uranium.

 

Izuku aimed at the rapidly spinning, over-stressed left tread of the Zero Pointer.

 

He pulled the trigger.

 

The recoil was so violent it dislocated Izuku’s left shoulder with a sickening CRACK. Izuku gritted his teeth, swallowing a scream.

 

The uranium rod fired at mach 2. It struck the exact mechanical weak point of the left tread's main drive sprocket just as the machine shifted thousands of tons of weight onto it.

 

The sprocket shattered.

 

The left tread snapped, exploding outward in a storm of razor-sharp metal links.

 

With its left tread destroyed and its weight completely unbalanced by the falling building, the Zero Pointer’s gyroscopes failed. The machine leaned drastically to the left.

 

The sheer, monumental weight of its own upper body became its undoing. Gravity grabbed hold of the mechanical titan. The robot tried to correct itself, its massive arms flailing, but it was useless.

 

CREAAAK... SNAP!

 

The central waist chassis, unable to support the torque of the falling torso, sheared completely in half.

 

The upper half of the Zero Pointer detached and plummeted to the earth. The impact caused a localized earthquake. A massive cloud of dust, smoke, and debris billowed hundreds of feet into the air, obscuring the sun.

 

Then, absolute silence descended upon Battle Center B.

 

 

 

Slowly, the dust began to clear.

 

The applicants, who had stopped running when the earth shook, turned around. They stared in slack-jawed, horrified awe.

 

The unkillable obstacle, the Zero Pointer, was a smoking, bisected mountain of scrap metal.

 

Standing in front of the wreckage, completely dwarfed by the scale of destruction, was Izuku Midoriya. His black compression suit was covered in grey dust. His left arm hung limply at his side, clearly dislocated. He was breathing heavily, his chest heaving as he stared up at the ruined machine.

 

He looked down at his wrist-pad. It was cracked, but functioning.

 

Zero Pointer neutralized. Kinetic redirection successful. Left shoulder dislocated. Exosuit battery depleted.

 

Izuku reached over with his right hand, gripped his dislocated left arm, took a deep breath, and violently shoved the joint back into the socket.

 

He let out a sharp hiss of pain, rolling his shoulder to check the mobility.

 

"TIME'S UP!" Present Mic’s voice echoed across the silent city. "THE EXAM IS OVER!"

 

A long, piercing buzzer sounded.

 

Izuku sighed. He tapped a button on his suit, disengaging the heavy hydraulic braces. They hissed and unlocked, allowing him to step out of the heavy leg attachments. He felt exhausted, but his mind was already cataloging the repairs he needed to make to the gear.

 

The other applicants slowly approached him. They looked at him as if he were an alien.

 

Iida stepped forward, his eyes wide behind his glasses. He looked at the destroyed robot, then down at Izuku. "You... you didn't have a Quirk that could do this. You have no physical enhancement. How... how did you do that?"

 

Izuku looked at Iida. His adrenaline was fading, leaving behind a cold, clinical exhaustion.

 

"I applied the principles of structural engineering and kinetic leverage," Izuku said softly, his voice lacking its usual rapid-fire cadence. "I used the environment. The robot was too heavy to support its own structural integrity if its weight was misaligned. I merely provided the misalignment."

 

Uraraka limped over, supported by the scaled boy Izuku had saved earlier. She looked at Izuku with tears in her eyes. "You saved me. You stopped that thing just to save me."

 

Izuku looked at her. "Your death or injury was an unacceptable variable. I removed the variable."

 

Before anyone else could speak, a small, elderly woman in a nurse's outfit walked through the crowd. Pro Hero Recovery Girl. She passed out gummy bears to the exhausted applicants before reaching Izuku.

 

"Well, well," she muttered, looking at his bruised shoulder and the destroyed titan behind him. "You certainly made a mess, young man. Nezu told me to keep an eye on you. Let me heal that shoulder."

 

"Thank you, ma'am," Izuku said, bowing slightly. "Though I request you limit the healing to the joint capsule. My current stamina levels are low; a full cellular regeneration might induce a hypoglycemic coma."

 

Recovery Girl blinked, then laughed softly. "Smart boy. Just a kiss for the joint, then."

 

She extended her lips and kissed his shoulder. Izuku felt a sudden drain of energy, but the sharp pain in his shoulder faded to a dull ache.

 

He picked up his discarded leg braces, strapped them to his backpack, and began the long walk back to the entrance gates. He didn't look back at the cheering applicants or the destroyed robot. He had achieved his objective.

 

 

 

One Week Later.

 

Izuku sat at his desk in his bedroom. The room was dark, save for the glow of the desk lamp. He was currently reading a collegiate textbook on fluid dynamics, taking meticulous notes in the margins.

 

"Izuku!" Inko burst into the room, holding a plain white envelope sealed with the U.A. wax stamp. Her hands were shaking so badly she almost dropped it. "It's here! The letter!"

 

Izuku calmly marked his page, closed the textbook, and took the envelope from his mother.

 

"Thank you, Mother. You can breathe now."

 

"I'll... I'll wait outside!" Inko squeaked, retreating from the room and shutting the door.

 

Izuku looked at the envelope. He knew he had passed. He had calculated the minimum point threshold based on historical data. But the final placement was the variable he wanted to confirm.

 

He opened the envelope. A small metal disk fell out onto the desk.

 

A holographic projection flickered to life. But it wasn't All Might, as was standard for the applicants.

 

It was Principal Nezu, sitting at his desk, sipping tea.

 

"Greetings, Izuku!" Nezu chirped cheerfully. "I requested to do your evaluation video personally, as standard protocol simply wouldn't suffice for our resident anomaly."

 

Nezu set his teacup down and folded his paws.

 

"You scored seventy-two villain points in the practical exam. A highly respectable score, second only to applicant Katsuki Bakugo, who scored seventy-seven."

 

Izuku nodded. He expected that. Katsuki's destructive output was undeniably efficient for point-gathering.

 

"However," Nezu's smile widened. "As you correctly deduced during the exam, a hero course cannot grade its students solely on destruction. There is a hidden metric. Rescue points. Given by a panel of judges for acts of selflessness and tactical protection."

 

A video feed appeared next to Nezu's head. It showed Izuku pulling the scaled boy away from the Three-Pointer. Then, it showed Izuku collapsing the building to drop the Zero Pointer and save Uraraka.

 

"For the flawless execution of risk assessment, civilian protection, and the sheer, unadulterated brilliance of weaponizing physics against an impossible obstacle... the panel awarded you sixty rescue points."

 

Izuku's eyes widened a fraction of a millimeter. Sixty.

 

"One hundred and thirty-two points total," Nezu purred. "A new school record. You completely shattered the curve, Izuku. The admissions board spent three hours arguing over your methods, but they could not argue with your results. You proved that intellect is a power far greater than any muscle."

 

The hologram zoomed in on Nezu's face. The principal looked deeply, genuinely proud.

 

"Welcome to U.A., Izuku Midoriya. You are officially the first-place student of the Hero Course. I eagerly await the chaos you will bring to my school."

 

The hologram faded.

 

Izuku sat in the silence of his room. He looked at his hands. They weren't glowing with power. They weren't generating explosions. They were just normal, calloused human hands.

 

But they had torn down a titan.

 

Izuku smiled—a small, cold, highly satisfied smile. He pulled out a fresh notebook, titled it 'U.A. Faculty and Peer Analysis', and began to write. The game had just begun.
