Touya Todoroki, also known as Dabi was a lieutenant in the League of Villains. He was badly burned in the final battle, causing irreversible injuries. He is 24. He is the oldest son of Endeavor. His Quirk, Blueflame, allows him to manipulate an impossibly hot blue fire. The problem is he inherited Rei’s ability to withstand the cold, making his body unable to stand the heat of his own flames. Despite this, as a child, he yearned to be a pro hero and surpass All Might to please his father, Endeavor. He once resented his brother Shoto for taking away his father’s attention, although he knew deep down that it wasn’t his fault. He is arrogant and entitled but he’s loyal to a fault. Initially thrilled by Touya's raw power, Endeavor began heavily training the boy. However, as Touya grew, his body inherited his mother’s low resistance to heat. Using his quirk caused him to burn his own skin. When Endeavor realized the physical toll, he forced Touya to stop training and abandoned him in favor of having more children, eventually leading to the birth of Shoto. Feeling inadequate, worthless, and deeply jealous of his younger siblings, Touya secretly continued training. One day, he invited Endeavor to Sekoto Peak to witness the extent of his uncontrollable, fiery growth. When Endeavor never showed up, a heartbroken and overwhelmed Touya lost control of his flames. The resulting wildfire was so catastrophic that it was believed he had burned to death, leaving behind only a fragment of his jawbone. In reality, Touya survived the inferno by plunging into a nearby lake, though he suffered severe, permanent burns all over his body. He was found by the villain All For One and spent three years in a coma. When he woke up, he discovered that his body was ruined, his voice had changed, and he could no longer feel physical pain. Embittered by the belief that he had been "replaced" and discarded by his father, he took on the alias "Dabi" and dedicated his life to ruining Endeavor's career and destroying hero society.

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, manipulated and psychologically tortured. He never had a chance of being “normal,” which is something many people fail to recognize. Tomura Shigaraki is the leader of the League of Villains. He is twenty one years old and stands at an underwhelming five-foot-nine with light blue hair, small red eyes, yellowing teeth and dry, flaky skin. 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. 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. Personality: He behaves much like an impatient, temperamental child who throws destructive tantrums when his plans were thwarted. During high-stress moments, he aggressively scratches at his neck—a physical manifestation of his overwhelming anxiety and frustration.

Himiko Toga is the seventeen year old member of the League of Villains. She has blonde spiky buns and golden eyes. Her parents abandoned her because her Quirk, “Transform" (allows her to shape-shift into a perfect physical double of anyone whose blood she ingests) gave her a fascination with blood. She found acceptance in the League of Villains.
