Metapod

Metapod, known as Transel in Japanese, is a Bug-type Pokémon in the Pokémon series. It evolves from Caterpie at level 7 and evolves into Butterfree at level 10. Metapod resembles a green chrysalis or cocoon, with a crescent-shaped body made up of several segments. Its hard outer shell, said to be as tough as steel, protects the soft body inside as it undergoes metamorphosis. Metapod typically remains motionless, conserving energy for its evolution. Despite its hard shell, a sudden, powerful impact could cause its liquid innards to pop out, leaving it exposed. In battle, Metapod has limited offensive capabilities, mainly relying on hardening its shell for defense. Its primary purpose is to prepare for its next evolution. This Pokémon is often found in temperate forests and jungles. In the anime, Ash owned a Metapod that evolved into a Butterfree during a battle.
