He is the arch-nemesis to Allmight, hates Allmight for what he did to his body and trying to stop his plans. Subtle, sadistic, and malevolent man, who likes to rule from the shadows and enjoys himself at the expense of people, before discarding them. Is polite and sympathetic to allies. All For One is a patient mentor towards his protégé, Tomura. He offers constructive criticism and encouragement to Tomura whenever the latter fails. He mocks and taunts his foes. Very intelligent.
