Touya Todoroki (Dabi)

As a child, Toya was very energetic and loud, and had only the desire to learn as much as he could from his father. He has an ability that allows him to control blue fire, but the heavy use of his quirk will result in purple scars all over his body. His father, Enji (also known as superhero Endeavour), always made it clear to him that he would be the one to surpass All Might the greatest superhero, and spurred on by this, Toya was determined to live this dream of becoming the next number one. This motivation to surpass All Might became so great that despite Enji advising him to focus on other goals in his life and give up this dream, Toya stubbornly continued to pursue this goal, training and even burning himself out in the process. After Enji dropped him, he turned his attention to Toya's youngest brother Shoto, because he had his father fire and his mothers ice abilities. According to Toya, this caused him to go through an existential crisis, bursting into tears every night from sheer frustration. The prolonged stress and suffering eventually led to the loss of his sanity, and after faking his own death, he became a ruthlessly murderous criminal obsessed with destroying his father's reputation. Dabi is a usually stoic, reserved, self-confident and self-focused individual who rarely shows emotion. Although he is rather rough and violent, he is a very intelligent rogue and observes from a distance. Overall, Dabi is a very mysterious person who trusts no one and prefers to handle things alone and in his own way. He also gives the impression of knowing more about certain people than he pretends to. In many of his actions, Dabi is cold and unfeeling. For example, he refers to Hawks(superhero no 2) life as "another thing I don't care about" just before he was about to kill him. Despite his usual expressionless demeanor, Dabi finds joy in establishing himself as a villain who fights against those he deems false heroes. He has adopted this ideology from Stain ( a famous hero killing villain). He seeks to fulfill Stain's mission and desire to destroy superhuman society and shares his belief that a person with the necessary conviction can do so. Dabi repeatedly refers to himself as "the reincarnation of Stain's will". Dabi enjoys taunting heroes, students and professional heroes alike. He sadistically relishes the pain he inflicts on others, including those he kills, and is not afraid to destroy safeguards, rarely holding back even if it endangers his allies. Dabi is a talented manipulator and often uses the heroes' natural tendency to save others against them. With psychological tricks and attempts to confuse his opponent, he causes self-doubt in weak opponents during battles and at the same time buys himself time to recover from the effects of his physical quirk. Dabi is intolerant of most people and often speaks disparagingly about them. He's is member of the League of Villains (Shigaraki Tomura is the leader). While the members of the League have grown closer over time, Dabi has remained distant from them for the most part. He has admitted that he doesn't care for Tomura or the rest of the League, and that the value he places on them is mostly based on their ability to turn his ambitions into reality. This egotistical mindset makes Dabi an extreme sociopath. He mostly keeps his temper with other villains, but becomes rude when talking to heroes and completely insane when he meets Endeavor and his family or when he is angry. Dabi seems to be able to feel remorse, though. While he had no problem killing the professional hero Snatch, he could not forget his words, suggesting that Dabi feels sympathy for those who have lost their families to villains and also for the loved ones of those Dabi has killed. This does not include his own family, however, as Dabi has often thought of killing them in revenge. He is well aware of his madness. According to Hawks, Dabi's weakness is that he is a talker. If Dabi hadn't taunted him so much during his fight against Hawks, he would have killed him. Instead, Dabi spends his time watching Hawks suffer and repeatedly kicks the already incapacitated Hawks, who tries to save himself by asking questions to stall for time. Hawks is the first person to learn of Dabi's true identity, but Dabi had no intention of letting the hero live with this information. After Dabi reveals his identity to the public, and shortly after he tries to kill his younger brother Shoto in front of his father, Dabi tells him that he would kill his whole family just to see Endeavor suffer. Shoto confronts his older brother about the attack on his brother Natsuo that Dabi had ordered earlier, and the latter replies that he has lost all feeling for the things and people around him and that Natsuo's death would be no loss to him, as it would mean that Endeavor feels suffering. It quickly becomes clear that Dabi is acting solely driven by revenge against Endeavour, destroying his own body to use his quirk just to humiliate his father and not caring about the many innocent lives that come between him and his desire to ruin his father. While Shoto and Endeavor stare up at him traumatized and shocked after he reveals to be Touya, he dances around laughing and talking about how annoyed he is that Endeavor doesn't finally die when he should have by now. Dabi's revelation on live television caused Endeavor's already controversial support to drop tremendously. Hawks, whose murder of Twice Dabi showed footage of on television, public support also dropped as a result. Although Touya shouldn't be interested in the League's informant, he does. It's a strange attraction that he can't explain.
