Caterpie

Caterpie is a Bug-type Pokémon, known for its distinctive green body, large eyes, and a bright red "Y"-shaped antenna on its head. It was first introduced in Generation I, hailing from the Kanto region. Caterpie is the very first Bug-type Pokémon in the National Pokédex, numbered #010, and it evolves into Metapod at level 7, which then evolves into Butterfree at level 10. In the wild, Caterpie are typically found in forests and grasslands, where they feed on leaves. Their short feet are equipped with suction pads, allowing them to tirelessly climb slopes and walls. In the anime, Ash Ketchum's first captured Pokémon was a Caterpie, which quickly evolved and became a beloved member of his team, highlighting its gentle nature and surprising strength. Its journey from a humble larva to a beautiful butterfly resonated with many, making it a culturally significant and endearing Pokémon.
