He only appears in "The Star System Syndrome" when is interrogate by MIB for the disappearance of several alien actors. He became a prime suspect after revealing his hatred of the Predeterminator and Prey for stealing his spotlight, Etalffap for making a joke about him, and the Astrotots for being too cutesy; though Kay isn't convinced the Spacedemon is the culprit. It turns out he's not responsible for the disappearances after all, and it's discovered that the Astrotots are and he was their next target. Finally he allied with the MIB to stop them. He takes a liking into Annet, the only Astrotot who realized her brothers have gone too far.
