Sir Evil, or Malvadon, was an evil Martian. Sir Evil was the primary antagonist in Generic Quest season one, and was responsible for the event that exterminated almost all life on the planet Mars. He planned to destroy Earth by crashing the Moon into it. "Sir Evil" was a name made up by Blavinoid Marcalium in order to avoid telling the heroes his true name (Malvadon), as it is a terrible word to utter in the Martian tongue.
