Who is Red Hood? - DC Secret Files & Origins

Death can be a strange thing for superheroes, especially when it doesn’t quite stick. Just ask Jason Todd. As Batman’s second Robin, Jason died at the hands of the Joker when he was just a child. But he returned to life with the help of a Lazarus Pit and the literal warping of time and reality. He trained himself to be a killer and a mercenary, and he took on a new identity and code name—the Red Hood—in order to strike his own brand of fear in Gotham’s criminals.
