His face got fucked up real bad after an unfortunate incident with some explosive diarrhea, and he resorted to a life of selling pure cocainum and making robot blow up dolls of people. Like every other character in the 80s, Sharaz wanted to bone Peri hard even though she didn't want it, and fantasied about her getting gangbanged by multiple android versions of herself (this will never happen to you). Oh yeah, and he was gonna be played by Bowie, but he knew that Doctor Who was a fucking shit show because he was a fan.
