Skeletor is the skull faced villain from Masters of the Universe, popularised by the 1983 He-Man and the Masters of the Universe cartoon where Alan Oppenheimer voiced him as a shrieking, insult hurling tyrant. His put downs aimed at Beast Man, Trap Jaw and his other minions became a defining part of the character. Short clips of those insults later spread on soundboards and in meme edits, where Skeletor is used less as a genuine threat and more as a camp, over the top voice of disapproval.
