Jason Peter Todd is a character appearing in American comic books published by DC Comics. First appearing in Batman #357 in March 1983, he was created to succeed Dick Grayson as Robin, Batman's partner and sidekick. He initially shared a similar origin to Grayson, being the son of circus acrobats who are killed by criminals in Gotham (Dick's were killed by a local mob boss who sabotaged their trapeze while Jason's parents were killed by Killer Croc) and adopted by Bruce Wayne/Batman as his son and protege. Following the Crisis on Infinite Earths event and the rebooting of DC's main comics universe, Jason's origin was changed to being a pre-teen street urchin and petty thief who Bruce adopted and took under his wing after finding the boy attempting to steal the tires off of the Batmobile. This origin has since become the standard for subsequent iterations of the character. Following Max Allan Collins's revamping of Todd's origin story in Batman #408–411, the character was written by Jim Starlin, who had him become increasingly aggressive and reckless. This led DC Comics to conduct a telephone poll concerning the 1988 storyline "A Death in the Family" to determine whether the character should die at the Joker's hands. The poll ended with a narrow majority of votes in favor of killing Todd, resulting in his death. Subsequent stories dealt with Batman's guilt over failing to save him. The character was resurrected in the 2005 "Under the Hood" story arc, which saw him becoming a murderous villain known as the Red Hood. In the current New 52/DC Rebirth continuity, Todd is a more nuanced antihero who maintains a tense, albiet partially mended relationship with Batman and has been accepted as a full member of the Batman family. Todd has made several appearances as Robin and Red Hood in other forms of media outside of comics, including television series, films, and video games. The 2015 game Batman: Arkham Knight in particular reimagined Todd resurfacing with a new villain identity, the Arkham Knight, following 10 years trapped in Arkham Asylum and tortured by The Joker who conditioned him to despise and turn on his former mentor before assuming the Red Hood identity near the end of the game.
