Marjorine (character)

Marjorine is the female alter-ego of Butters Stotch. She made her only appeared in the episode "Marjorine" after Butters' death was faked to get hold of the girls' "device" at Heidi Turner's slumber party and ran off with it. It is unknown whether the girls realized at that point that Marjorine was really Butters. Her actual persona has appeared in many other episodes.

Marjorine's mother (which was really just Cartman) made sure Butters went to the party and the other boys kept watch outside the Turner Residence.
