Pikachu has been the mascot of Pokémon since the franchise began in Japan in 1996, and its bright yellow design and electric powers have made it recognisable around the world. Clips like this circulate widely in gaming and fan communities, where a short burst of Pikachu's voice is enough to signal nostalgia, excitement or a playful start. The Let's Go name also connects the sound to the Pokémon Let's Go games for Nintendo Switch, which introduced many new players to Pikachu as a travelling companion. Its brevity makes it easy to drop into edits without slowing them down.
