The clip comes from the Who's That Pokemon segment of the Pokemon animated series, a recurring guessing game that appeared between scenes in the English-language episodes during the late 1990s. Viewers were shown a shadowy silhouette and asked to guess the Pokemon, before the answer was revealed with its name and music. The format became a lasting piece of Pokemon nostalgia, and short clips of the Pikachu reveal circulated widely on Vine, YouTube and later TikTok as a quick way to signal a reveal. It remains popular because the jingle is instantly recognisable.
