Mr. Popo is a character from the Dragon Ball anime series, where he serves as the attendant to Kami at the Lookout. His unsettling laugh became a memorable part of his portrayal, and fans later isolated it as a short soundboard clip for memes and edits. It spread through Dragon Ball fan communities and meme pages, where it was used to caption scheming, creepy, or unexpectedly villainous moments. Its staying power comes from that contrast: a normally calm, helpful character delivering a laugh that sounds far more sinister than expected, making it instantly recognisable to Dragon Ball fans.
