The Elements of Insanity are the protagonist villainesses from the eponymous GMod videos. They were created when the main characters of My Little Pony Friendship is Magic ended up possessed by the ghosts of various "Freak Fortress" characters and creators, giving them supernatural abilities and warping their minds. The Elements of Insanity are not "evil" per se, but as is typical for Freak Fortress characters they are extremely chaotic.
