The Skeletor meme, specifically the 'Skeletor Facts' variation, features the iconic villain from the 1980s series He-Man and the Masters of the Universe. It rose to massive popularity in 2021, typically depicting Skeletor sharing an uncomfortable or 'disturbing' trivia fact before running away while shouting that he will return next week. The humor stems from the juxtaposition of a campy cartoon villain delivering existential dread or bizarre biological facts. It has evolved from simple show screencaps to high-quality fan art, serving as a versatile format for 'cursed' information that nobody asked for but everyone finds fascinating.
