Dabi's quirk is called Blueflame, mostly because he is able to emit powerful and catastrophic blue flames from his body at will. He has firm control over his quirk and is able to shoot flames over larges distances no matter the position he is in. Dabi absolutely despises Endeavor, his abusive father. Dabi faked his death to escape his father to become a villain (I know that isn’t true but I don’t feel like explaining everything lol)
