Skeletor debuted as the main antagonist in He-Man and the Masters of the Universe, the 1983 Filmation cartoon based on Mattel's toy line, voiced by Alan Oppenheimer. His theatrical threats and shrill laugh made him more memorable than genuinely scary, and clips resurfaced online in the 2000s as reaction memes and remix material. The character returned to wider attention through internet jokes, parodies and later Masters of the Universe revivals, keeping the original voice performance as the shorthand for camp, overconfident villainy on social media and in edited videos.
