Brawn Boost
CharacterA plain power-up with a brutal twist in whose hands it landed. Brawn Boost raises physical strength, nothing more complicated than that, but All For One holds three copies of it at once, stacking the effect far beyond whatever its original owner could have managed.
Overview
Brawn Boost, rendered in Japanese as Ryoryoku Zōkyō, is one of the many Quirks in All For One's collection. He did not develop it; he stole it from a person the story leaves unnamed. Its classification is Emitter with a power-up range.
The ability appeared in Chapter 93 and in Episode 49 of the anime, with a later manga showing in Chapter 397. The wiki files it under villain Quirks and All For One's Quirks. It has also been called Strength Enhancer.
Mechanics
The name does the explaining. The Quirk raises its owner's physical strength, and that is the whole of the effect.
Where it becomes dangerous is in stacking. All For One does not carry one copy of this power, he carries three, and running them together drives both its potency and its output well past what a single instance would deliver.
Notable Users
All For One is the user on record, holding three copies of the Quirk simultaneously and folding it into the larger stack of stolen abilities he brings to a fight.
An unknown person owned it beforehand and lost it to his theft. Nothing about that original holder has been revealed.
