Metapod is a Pokémon species introduced in the first generation of the Pokémon series. It is known for its green, cocoon-like appearance and is the evolved form of Caterpie. Metapod primarily focuses on defense, as it cannot attack and relies on its hard shell to protect itself from predators. In the Pokémon games, Metapod evolves into Butterfree at level 10. While it may seem inactive, it plays a crucial role in the evolution process, allowing players to develop stronger Pokémon. Metapod is often associated with the themes of growth and transformation in the Pokémon universe.
