The homicidal and long-time enemy of Batman, Joker was chosen by the Light to be one of the seven members of their decoy group the Injustice League; however, he didn't know he was being used. His role was to control the numerous Kobra-Venom powered plants attacking the world. After the Team take out the control plant, Joker attacks Robin. Once the Justice League shows up to arrest them, Joker attempts to kill them all with his Joker Venom, which Dr. Fate sucks into a portal to save them.

Joker was then reincarnated in Arkham Asylum.
