Stan's Goldfish

Stan's Goldfish is an evil killer goldfish from a South Park episode, Spookyfish, where it was given by Aunt Flo. It kills Kenny and Aunt Flo.

Stan was aware of the fish's malevolent nature and tried desperately to tell his mother and anyone else about it, yet due to the absurdity of the tale (even for South Park) nobody would believe him - when people started to get murdered Stan's mother believed it was Stan who was doing it - though instead of turning her son over to the police she covered up the murders (funnily enough this technically makes Stan's mother a minor villain since she is committing several crimes).&nbsp
