One For All

Mythic

The legendary power-stockpiling Quirk passed down through generations, accumulating the strength of every previous user. Inspired by Deku and All Might from My Hero Academia, One For All grants superhuman strength, speed, and durability. Likely the rarest and most powerful Quirk in ITAMI. Features a unique Full Cowling system — percentage-based power activation that scales both strength and risk.

Awakening

One For All has TWO separate Mythic versions: the Deku path (progressive Full Cowling %, culminating in 100%) and the All Might path (raw overwhelming power). To awaken, you must complete multiple questlines and defeat your Inner Self in the Void of your Mind — an AI that studies your inputs and mirrors your combat style back at you. Developer confirmed awakening is extremely difficult to obtain with multiple stages. At 100% OFA may cause self-damage referencing Deku's early arc.

Unique Mechanic: Full Cowling (percentage-based power activation) — TWO Mythic paths: Deku & All Might

Abilities

Detroit Smash

Melee attack

A powerful OFA-charged fist strike that generates a shockwave on impact. Knocks the target back and deals massive damage. The signature attack of One For All users.

Effects: High damage + Knockback + Shockwave

Range: CloseCooldown: ~6-8s

Combo Tip: Ideal finisher after M1 combo — the knockback creates distance for reset.

Full Cowling

Buff / Activation

Activates Full Cowling — OFA energy envelops the entire body. Grants a significant speed boost and damage increase to all M1/M2 and Quirk attacks for a limited duration. Higher percentage = stronger buff but potentially more self-damage.

Effects: Buff — Speed boost + Damage boost (timed)

Range: SelfCooldown: ~15-20s (with buff duration)

Combo Tip: Activate early in a fight — the speed and damage boost makes every combo deadlier.

Manchester Smash

Aerial attack

The user leaps high into the air, flips, and delivers a devastating downward axe kick. The impact creates a crater and deals massive knockdown damage. Excellent for initiating or catching aerial opponents.

Effects: High damage + Knockdown + Terrain destruction

Range: MediumCooldown: ~12-15s

Combo Tip: Use to catch opponents after knockback — the aerial approach is hard to react to.

United States of Smash

Ultimate

The user channels ALL of One For All's power into a single, final punch. The strike generates a massive shockwave that devastates everything in range. Potentially the most powerful single attack in the entire game.

Effects: EXTREME damage + Massive Knockback + Terrain destruction + AoE shockwave

Range: MediumCooldown: ~40-60s

Combo Tip: Save for the kill — this is your finisher. Best when opponent has no Dash or Block.
