Tomura Shigaraki (Tenko Shimura) Tomura Shigaraki, born Tenko Shimura, is the main villain of My Hero Academia. His story is one of tragedy, manipulation, and the consequences of a society that failed to help someone in need. As Tenko, he was a small boy with pale blue hair and red eyes. As Shigaraki, he has messy white hair, red eyes, and a thin, worn appearance. Early in the series, he often wears the severed hands of his family members over his body and face as a reminder of his past. Shigaraki starts out impulsive, immature, and full of hatred toward hero society. As the story progresses, he becomes more focused, intelligent, and frighteningly determined. Deep down, traces of Tenko's pain and loneliness still remain beneath the anger. Shigaraki's Quirk, Decay, allows him to destroy anything he touches with all five fingers. People and objects crumble into dust almost instantly. Later, the destruction can spread from one target to everything connected to it. After gaining additional power, his abilities become devastating on a massive scale. Tenko was the grandson of Nana Shimura, a former wielder of One For All. He grew up in an abusive household where his dream of becoming a hero was discouraged. When his Quirk manifested, a tragic accident destroyed his family. Lost and alone, he was taken in Inko, but tooken again by All For One, who manipulated his grief and anger, shaping Tenko into the villain known as Tomura Shigaraki. He eventually becomes the leader of the League of Villains, until rehabilitation starts.
