Originating from the commercial break bumpers of the 1990s Pokémon animated series, the 'Who's That Pokémon?' segment challenged viewers to identify a pocket monster by its silhouette. Over time, the internet transformed this simple quiz into a versatile bait-and-switch meme format. It often features a silhouette that clearly resembles a popular Pokémon like Pikachu, only to reveal a completely unrelated, cursed, or humorous image when the reveal happens. This format is a staple of nostalgia-driven humor, frequently used to subvert expectations or mock obvious mistakes in a playful, recognizable way.
