Caterpie first appeared in the original Pokemon games, Pokemon Red and Green in Japan in 1996, and became widely familiar through the Pokemon anime that followed, where its distinctive game cry was reused for the character. As clips, soundboards and short-form edits spread online, the short chirp became a handy shorthand for cute, harmless Bug-type Pokemon and for early-game nostalgia. It remains popular today because it is instantly recognisable to long-time fans, yet short and light enough to drop into memes, gameplay videos and reaction edits without distracting from the scene.
