Metapod

Metapod (Japanese: トランセル Toranseru) is a -type Pokémon introduced in Generation I. It is the evolved form of Caterpie.

Physiology
Metapod is an insect-like Pokémon with an appearance similar to that of a green colored chrysalis or cocoon. Although it is covered in its hard shell, Metapod's eyes are still clearly visible and usually appear dazed, drowsy, or angry for reasons unknown.

Natural abilities
Metapod have the ability Shed Skin which allows for a 1/3 chance that a harmful status effect will be dropped every turn.

A Metapod's exterior is regularly hardened to protect its soft and tender innards while undergoing metamorphosis to eventually become a Butterfree. To conserve energy for this event, the Metapod barely moves.

Evolution
Metapod evolves from Caterpie starting at level 7, and evolves into Butterfree starting at level 10.

Anime
Metapod first debuted in the anime episode Ash Catches a Pokémon when Ash Ketchum's Caterpie quickly evolved into a Metapod near the episode's end.

In the episode Challenge of the Samurai, Ash battled a Samurai-like trainer using his Metapod against the Samurai's Metapod.

Gym Leader Bugsy used his own Metapod against Ash in the episode Gettin' the Bugs Out. This Metapod proved to be more capable than others in previous episodes as it was actually able to knock out Ash's Chikorita.
