Pikachu first appeared in the Pokémon video games in 1996 and became the franchise mascot through the long-running anime series, where its pika pika cry was voiced by Ikue Ōtani. The phrase is not a sentence in any human language, but fans recognise it instantly as Pikachu talking, cheering or calling for attention. Clips of the cry spread through Pokémon games, cartoons, toys and later meme edits and short-form videos, where creators reuse it as a shorthand for cuteness, excitement or playful surprise, keeping a sound from the 1990s familiar to new audiences.
