Tomura Shigaraki

Born Tenko Shimura, his life was irrevocably shattered the moment his Quirk, Decay, awakened without warning during childhood, inadvertently killing his entire family. Left utterly alone with nowhere to turn, he was taken in by All For One, who rechristened him Tomura Shigaraki and molded him into a weapon of destruction. Consumed by a burning resentment toward the hero-dominated world, he dedicates himself to tearing down every pillar of the existing social order. His arc across the series is one of the most compelling villain journeys in modern anime—transforming from a reckless, emotionally volatile delinquent into an existential threat capable of challenging heroes and society alike.
