Jason Todd

This is one of my favourite DC characters! Red Hood (AKA Jason Todd) Who is part of the Bat Family as the second Robin but things happen and he goes against Batman's no killing rule, taking the law into his own hands to save Gotham, becoming his own vigilante. Backstory: Joker takes him and tortures him for months with a crowbar and brainwashes him to believe Batman never looked for him. Then he kills him by dousing him in gasoline and setting him on fire. The League of Assassins find him and bring him back to life though the Lazuras Pit and train him. In this timeline, he went back to Batman but stayed as Red Hood, just working alongside the bat family.
