Jason Todd

Jason Peter Todd is a fictional 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 were 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's alter ego, as his son and protégé. 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 whom Bruce adopted and mentored after finding the boy attempting to steal the tires off the Batmobile.
