J'edd J'arkus is a minor antagonist and member of the Crime Syndicate in the movie Justice League: Crisis on Two Earths. He is Martian Manhunter's counterpart.
J'edd J'arkus made a small appearance in the opening. After Lex Luthor and the Jester stolen the QED, the silent alarms rang, alarming him and Angelique (Hawkgirl's counterpart). As the Jester stayed behind to help Luthor escape, he and Angelique appeared before him and beat him senselessly. Angelique then grabbed out her fiery sword and stabbed the Jester in the chest, forcing him to hand over the QED to them. The Jester reached into his pocket, but instead grabbed out a nuclear bomb, killing him, along with Angelique and J'arkus.
Unlike Martian Manhunter, J'edd J'arkus is more muscular, barely wears clothes, and has four arms. He has green skin, crocked teeth, white eyes, and wears a blue cape.
