Overview

Charging Muscles belongs to the villain Muscle Man. It is filed among Emitter Quirks and functions only at close range, which suits a power that resolves into a physical blow.

Mechanics

Strength builds up inside the muscles before it is spent, so an attack that would land normally instead arrives with amplified force. The charging step is what separates it from ordinary physical power.

The tradeoff shows up when Muscle Man pushes the buildup past what his body tolerates. Overcharging leaves him with severe muscle soreness in the aftermath.
