As a child Jason's mother taught him acrobatics and his father taught him martial arts. His parents were both acrobat performers in the circus. They were eaten by Killer Croc when he was eight.

Jason was approached by S.U.P.E.R. (Secret Underground Patrol Espionage Rally) and recruited into the Justice League when he was twenty. He kept his distance from the other members.
During a solo mission Nightwing fought the Joker. Joker had the upper hand and he beat Nightwing to near death. Joker then shot him through the head. After his death, the Justice League hunted Joker and arrested him.
