The quintillionaire alien mob boss who escaped from his cell on Penal Planet 10. He appears as a feline muscular humanoid with dark hair streaked with red over all the body, a voluminous red mane and beard, and an eyepatch (with the symbol of a black star) covering his left eye. Utilizing beams from Limbo's Moonstar and the use of his Transformation Chamber, Mon*Star's body becomes encased on spiked armor-plating as he recites "Moonstar of Limbo, give me the might, the muscle, the menace, of MON*STAR!". In this state, he temporarily regains his left eye with it able to fire the crimson Light Star beam which has various effects, destructive and stunning. He has some bad blood with Stargazer due to their past conflicts and extends that animosity to the SilverHawks. Mon*star appears in all but two episodes (episodes number 15 and 45) where Hardware and the Bounty Hunter are the villains respectively.
