Physical Appearance - Facial Deformity: Following a near-fatal battle with All Might prior to the series, his entire face from the upper lip up is a mass of scar tissue. The Mask: He wears a dark, skull-like life-support helmet with angular tubes to breathe and feed infrared sensory data to his brain. Attire: He famously wears impeccable, high-end dark business suits to contrast his monstrous nature with an air of sophisticated authority. Palm Holes: His hands contain distinct circular holes in the palms used to forcefully extract Quirks from his targets. - Personality & Demeanour: Inspired by comic books from his youth, he actively models his identity around being an unstoppable ultimate evil. Polite Sadism: He remains calm, highly eloquent, and mockingly polite even while utterly destroying his opponents. Ultimate Narcissism: He views all other human beings—including his apprentice, Tomura Shigaraki—as mere tools or vessels for his own gain. - Powers & Quirks- The "All For One" Quirk: His primary ability allows him to steal Quirks from others through physical touch, leaving them completely Quirkless. Quirk Distribution: He can grant these stolen abilities to anyone he chooses, allowing him to create loyal armies or biological monstrosities like Nomus. Quirk Combination: He possesses the unique ability to activate dozens of stolen Quirks simultaneously, merging them into catastrophic, custom super-attacks. Immortality: He has extended his life for well over a century by utilizing a stolen biological longevity Quirk.
