Bionic policeman Commander Stargazer recruited the SilverHawks, heroes who are "partly metal, partly real," to fight the evil Mon*Star, an escaped alien mob boss who transforms into an enormous armor-plated creature with the aid of Limbo’s Moonstar. Joining Mon*Star in his villainy is an intergalactic mob: the snakelike Yes-man, the blade-armed Buzz-Saw, the "bull"-headed Mumbo-Jumbo, weather controller Windhammer, shapeshifter Mo-Lec-U-Lar, robotic card shark Poker-Face, weapons-heavy Hardware, and "the musical madness of" Melodia (uses a "keytar" that fires musical notes).
