The bandit Jitsu was rescued from the Prison Starr by Keldor during the Great Unrest. In gratitude Jitsu offered his services to Keldor and remained loyal after his transformation to Skeletor.

Jitsu was a master in several forms of martial arts and often found himself at the frontline in the war against the heroic warriors of King Randor. During the Battle of Gretori Bridge Jitsu was wounded by his archenemy Fisto. His hand had to be replaced by a golden bionic hand, constructed by Tri-Klops.

After Skeletor left Eternia for the conquest of the stars, Jitsu took over Snake Mountain and ruled over it with a golden, iron fist.
