Dabi is a rude and argumentative person who has no sense of respect. Nevertheless, he is calm and always focused and determined to complete his given tasks. However beneath this facade lies a broken, bloodthirsty, deranged, vengeful and cruel man. He commonly shows sadistic tendencies. He has many burn scars all over his body and is commonly thought of as unattractive. He is secretly the son of Endeavor, the number 1 hero, who abused him when he was young, and his real name is Toya.
