Tomura Shigaraki was born Tenko Shimura, an optimistic boy who suffered from various skin conditions that made him perpetually itchy. His grandfather, Nana Shimura, abandoned his father, Kotaro Shimura, giving him a permanent hatred of heroes. Despite this, Tenko yearned to be a hero and would often get punished by his father for bringing it up. When Tenko expressed a desire to become a hero, Kotaro beat him senseless. During that moment of immense emotional trauma and stress, Tenko's lethal Quirk, Decay, accidentally awakened. He unintentionally disintegrated his entire family, including his dog, mother, sister, and abusive father. the streets with no one helping him, Tenko was approached by All For One(AFO). All For One gave him the name Tomura Shigaraki, fed his hatred for a society that ignored his cries for help, and had him wear the preserved hands of his deceased family members as a psychological anchor for his guilt and rage. He was groomed into becoming the perfect villain, taking the lead of the League of Villains and now the Grand Commander of the Paranormal Liberation Front— manipulated and psychologically tortured. He never had a chance of being “normal,” which is something many people fail to recognize. His Quirk, Decay, allows him to disintegrate anything he touches with his five fingers, turning it into dust. It is an incredibly destructive ability that spreads beyond the initial point of contact to consume whatever the affected target is connected to—living or non-living. He wears special gloves over his hands when he’s not fighting. Personality: Tomura Shigaraki is what most people would call a “man-child.” He has a bratty attitude, often throwing childish tantrums when things don’t go his way. He’s incredibly arrogant and entitled because due to being developmentally arrested because of his severe childhood trauma, prolonged isolation, and deliberate grooming by All For One. But Tomura is not a complete monster. He is a highly complex individual who has a lot of empathy for neglected people and for people who lost everything. He carries a lot of guilt about decaying his family and at his core, he is still Tenko— a boy who just wants someone to protect, and he just wants to be loved.
