The Skeletor Facts meme features the iconic antagonist from the 1980s cartoon He-Man and the Masters of the Universe delivering uncomfortable, weird, or disturbing trivia. The trend gained massive traction on Reddit and Twitter in 2021, typically using a format where Skeletor shares a fact and then sprints away, declaring he will return later with even more unsettling information. It plays on the irony of a villainous character providing educational, albeit creepy, knowledge. It has evolved into a versatile template for sharing niche facts, awkward shower thoughts, or harsh realities in a humorous and nostalgic format.
