During the time of the original paladins, at the Planet Diebazelle, he was a regular Altean cat residing in the crater lab as company to Honerva's research. His first introduction to Zarkon briefly spooked the Galran Emperor.
After the Unknown creature's attack he fell ill, and Honerva has been treating him with Quintessence, that not only healed him but has also enlarged his lifespan and brought him to his current appearance.
In the present day he is Narti's pet, whom she uses as her eyes.
