Rikiya is a tall and muscular man.
He wears a black tank-top with jeans and sneakers, as well as a plague mask that covers his head.
Enhanced Strength: Even without activating his Quirk, Rikiya exhibits superhuman brawn, befitting his massive build. On two separate occasions he effortlessly burst through a wall and a locked gate, knocking several policemen into the air while doing so, and casually damaged the jamb while readying his next punch.
Enhanced Durability: Rikiya was able to shrug off an attack from a weakened Nejire Hado.
Vitality Stealing: Rikiya's Quirk allows him to inhale and absorb others' stamina (vitality) after touching them. He can also use the energy to increase his size. When enhanced by Trigger, Rikiya does not have to be touching his target.
