The Who's That Pokemon segment comes from the Pokemon animated series, where a dark silhouette of a Pokemon was shown and viewers were asked to identify it before the reveal. The Spanish version, Quien es ese Pokemon, carried the same guessing-game format for Spanish-speaking audiences and became a nostalgic touchstone for fans who grew up watching the show. As clips circulated online, creators began reusing the question as a meme template for any surprise reveal, from new characters to unexpected answers, keeping it popular long after the original broadcasts.
