Triclops was a Human mutant slave who claimed to be the son of Emperor Palpatine. It is possible that this relation may not have been in a strict biological sense, and that Triclops was the implementation of Darth Plagueis's experiments in the influence of midi-chlorians, with the goal of creating a zygote solely through the use of the Force in a fertile humanoid female.

Triclops was a white-haired mutant with three eyes, one being on the back of his head, and sported scars on his temples from electroshocks administered by the Galactic Empire. He was trained to be an Emperor's Eye but Palpatine considered him one of his greatest failures and had him imprisoned. He languished for years in an Imperial prison on Kessel, often dreaming up the designs for unholy superweapons for the Empire during his unending nightmares.
