Trioculus was a three-eyed mutant warlord of the Galactic Empire who declared himself Emperor a year after the Battle of Endor. As a figurehead of the Central Committee of Grand Moffs, led by his mentor Bertroff Hissa, Trioculus took control of the remnants of the Empire in opposition to Ysanne Isard.
The self-proclaimed son of Palpatine, Trioculus was in actuality a pretender to the throne, usurping the role of Palpatine's alleged son, three-eyed mutant Triclops. Spurred on by a prophecy of the false Kadann, he sought the glove of Darth Vader to establish his legitimacy. Trioculus's pursuit of the Jedi Prince Ken and his infatuation with Leia Organa pitted him against rival Zorba Desilijic Tiure, and led to him being taken captive by the Hutt and frozen in carbonite. Trioculus was eventually betrayed by Kadann, who sought the Imperial throne himself, and in the end was assassinated by a New Republic droid.
