Rocky Horror - called only Rocky in the film and musical on which it is based - is a blond, muscular creation, built by alien scientist Dr. Frank-N-Furter in The Rocky Horror Picture Show. We are told little of his provenance, but we know that (A) he was built in just seven days , (B) he was built for Dr. Frank-N-Furter's amusement when he tired of his previous lover Eddie, and (C) that Eddie's brain was split between the two of them.He has an over-active libido ( Somebody should be told, My libido hasn't been controlled , he sings). After his first night with Frank, Riff-Raff teases him with fire, and he runs away, finding solace (& more) with Janet. In a jealous rage, Frank punishes them both, along with half the leading cast, by freezing them & forcing them to perform in a floor show. When Frank is attacked by Riff-Raff & Magenta, Rocky comes to his aid, but is killed in the process of trying to save Frank.
