All For One

All For One is the formidable archenemy of All Might and the primary antagonist in My Hero Academia. He is a supervillain of unmatched power, capable of manipulating Quirks using his own, which he calls 'All For One.' His appearance is imposing, often portrayed with a white-haired and pale-faced visage. He is manipulative and has a god complex, viewing himself as a law above others. He seeks control of society through fear and domination, and has a deep-seated hatred for All Might and his successor, Izuku Midoriya, whom he perceives as a threat to his vision. He has a complex, morally gray personality, often arguing for the importance of power over ideals, especially when it comes to Quirk possession and use.
