The quiet of my room was a stark contrast to the chaos of the U.A. Sports Festival, its echoes still ringing in my ears-crowds chanting my name, Bakugo's explosions, Todoroki's fire.
I sat cross-legged on my bed, the faint hum of Saiyan Physiology pulsing through me, a green aura flickering when I flexed. My hero costume hung in the closet, scuffed but ready for internships looming tomorrow.
The Sports Festival had made me a star, with offers from Hawks, Nighteye, even Endeavor, but the weight of my reality pressed harder: All For One, my father, stealing my quirk and erasing himself from Mom's memories. That truth, uncovered in a dream, gnawed at me, a wound no Senzu Bean could heal.
The Gacha System's neon interface flickered to life, unprompted, its mechanical voice cutting through my thoughts.
System Notice: Heroic alignment stable. New pull authorized. No further recalibrations required.
My heart raced-the system had reactivated fully after the festival, granting Zenkai Boost last time. Yesterday's "recalibration" had stripped skills like Adrenaline Surge, Enhanced Reflexes, and Combat Instinct, plus the Sonic Disruptor, Dagobah Beach debris, and-mortifyingly-Uraraka's underwear, citing my overpowered status and ethical concerns.
The Ticket to World: Dragon Ball Super was replaced with Knowledge of All Dangerous Spells (Harry Potter World), wandless magic now at my fingertips. Another pull now? I held my breath, willing the system to deliver.
Pull Result: Perk - Transform (S-Tier). Grants unlimited transformation into any person, creature, or object, retaining user's consciousness and abilities. No time or form limits. Stored in user's skillset.
I froze, processing. Transform-no limits? I could become anyone, anything, from a dragon to All Might himself, all while keeping my Saiyan strength, Major Telekinesis, and Harry Potter magic.
Perks weren't items, so this integrated directly into me, like my other skills. The system's timing felt deliberate-after All For One's memory, this perk could let me test truths no one else could.
An idea sparked, reckless but irresistible: disguise myself as All For One, unscarred, from before his fight with All Might. I could confront All Might and Mirio, the true One For All successor, to gauge their strength, their readiness against the Symbol of Evil.
My knowledge screamed caution-All Might was weakened, Mirio powerful but untested-but Transform could hide me completely. I had to know.
Inko was at work, giving me the day to experiment. I locked my door, heart pounding, and activated Transform. My body tingled, bones shifting painlessly, skin reshaping.
I visualized All For One from the dream-tall, sharp-featured, unscarred, dark hair slicked back, eyes cold but charismatic. My reflection in the mirror morphed: my freckled face became angular, green hair darkened, and my frame stretched to a towering height, clad in a black suit.
My voice deepened, smooth and menacing. "Perfect," I said, testing it. My Saiyan Physiology and magic remained, buried beneath the disguise. I'd need a safe place to test this-somewhere All Might and Mirio could fight without collateral damage.
Dagobah Beach, now clean from my pre-U.A. efforts, was ideal-isolated, open, no civilians. I whispered, "Apparition," one of my Harry Potter spells, and teleported with a crack, landing on the sandy shore.
The ocean breeze hit me, my All For One form untouched by the chill. My Saiyan senses scanned: no one nearby, perfect for a controlled test.
I sent a coded message via a burner phone (created with Major Telekinesis from spare parts in Dimensional Storage): All Might, Mirio Togata. Dagobah Beach. Urgent threat. Come alone. I signed it with a vague villain alias, knowing their hero instincts would draw them.
Minutes later, a sonic boom announced All Might's arrival, his emaciated form steaming into his muscular hero state, blonde hair gleaming. Mirio phased through a nearby dune, his Permeation quirk active, blue eyes sharp.
"Who are you?" All Might demanded, his smile tight but resolute. Mirio tensed, ready to phase. My All For One disguise held, voice smooth. "A shadow from your past, Symbol of Peace. Shall we test your legacy?"
All Might's eyes narrowed, sensing danger but not recognition-my disguise was flawless. "If you're a threat, I'll stop you!" He lunged, One For All surging, a Detroit Smash aimed at my chest.
My Saiyan speed dodged effortlessly, green aura hidden beneath the disguise. I activated Major Telekinesis, lifting a 50kg sand mound, hurling it at him. All Might punched through, shockwave scattering sand, but coughed, his form flickering-his injury from years ago weakening him.
Mirio phased, diving through the ground, reappearing behind me. "Gotcha!" His fist swung, One For All enhancing his strength, but I countered with a Protego spell, a magical shield deflecting his blow.
He blinked, confused. "What's that?!" I smirked, All For One's voice cold. "More than you can handle, boy." I used telekinesis to pin him, but he phased free, his training sharp. My knowledge noted: Mirio's One For All was raw, powerful, but unrefined compared to All Might's.
All Might charged again, a Texas Smash sending a wind blast. I tanked it with Saiyan durability, disguised as All For One's casual shrug, then cast Sectumsempra wandlessly, a cutting spell aimed low to avoid lethal harm.
All Might dodged, but the spell grazed his arm, drawing blood. He grunted, unfazed, and countered with a flurry of punches, each shaking the beach.
I telekinetically redirected his force, sending him skidding, and tested Transform further, shifting briefly into a dragon-scales, wings, towering size-before reverting to All For One. "Impressive, but not enough," I taunted, gauging his limits.
Mirio attacked, phasing through my telekinetic grabs, landing a solid hit to my side. Saiyan durability absorbed it, but I let him think it hurt, staggering for effect.
"You're strong, Togata," I said, "but unready for me." I cast Stupefy, a stunning spell, knocking him back. He rolled, recovering fast, One For All glowing. All Might rallied, his voice booming. "We'll protect this world!"
They synchronized, All Might's United States of Smash combining with Mirio's phased punch. The beach erupted, sand flying, but I apparated behind them, unharmed, and used telekinesis to lift them both, gently setting them down.
"Enough," I said, dropping the disguise. My body shifted back to Izuku-green hair, freckles, hero costume. All Might and Mirio froze, shocked. "Midoriya?!"
All Might gasped, deflating slightly, steam rising. Mirio blinked, "What... was that?!" I bowed, heart racing. "I'm sorry, All Might, Mirio. I needed to test your strength-my new ability let me disguise as a villain. No real threat."
All Might coughed, smiling weakly. "Young Midoriya, that was reckless... but your heart's in the right place. Your power's incredible."
Mirio laughed, clapping my shoulder. "You scared me, man! That was some quirk!" I didn't correct him-Transform wasn't a quirk, but a system perk. My Saiyan Physiology and magic stayed hidden, their One For All unaware of my anomaly.
The test confirmed: All Might was fading, Mirio strong but not yet his equal. Against All For One, they'd struggle-my father's shadow loomed larger.
We sat on the beach, catching our breath. All Might, still in his skinny form, shared wisdom. "Power like yours, Midoriya, needs purpose. Protect, don't just fight." Mirio nodded, "Yeah, you're gonna be a legend!"
Their trust warmed me, but guilt lingered-posing as All For One felt wrong, even if it was a test. I apologized again, and they waved it off, All Might's smile reassuring.
Back home, I reflected in my room, the system's interface silent-no new pulls, just Transform integrated into my skillset.
Inko greeted me with dinner, katsu curry steaming. "You look thoughtful, Izuku," she said, her green hair framing a warm smile. I hugged her, the All For One memory heavy but unspoken.
"Just... glad to be home, Mom." We ate, laughing over her stories, my hero life on pause. For now, I was just Izuku, testing new powers, ready for whatever came next.
