Jason Todd was the second Robin, sidekick to the superhero Batman. Jason was an orphaned street delinquent with a troubled past and violent demeanor, whom Batman attempts to reform and mentor. Years later, it is revealed that Jason had died at the hands of the Joker, but when Superboy-Prime alters reality from the paradise dimension in which he is trapped, Jason is restored to life and hospitalized, as the injuries inflicted by the Joker had not fully healed. After spending a year in a coma, he is recognized by a petty criminal who soon informs Talia al-Ghul. After some time, Talia restores his health and memory by immersing him in a Lazarus Pit. On Talia's advice, Jason determines his death was never avenged and prepares to confront Batman. When Batman expresses no remorse for sparing the Joker's life after Jason was killed, Jason is further enraged and takes up the mantle of the Red Hood.
