Skeletor is the skull-faced villain of He-Man and the Masters of the Universe, which began as a toy line and Filmation cartoon in 1983, voiced by Alan Oppenheimer. His theatrical cackle became part of the character's camp appeal, alongside his constant schemes against He-Man and Castle Grayskull. Decades later, clips and remixes on YouTube and meme pages revived the laugh as a standalone reaction, separate from the show itself. It endures because it instantly signals cartoon villainy in a way newer effects cannot match.
