Pikachu (Japanese: ピカチュウ Pikachu) is an Electric-type Pokémon introduced in Generation I.

It evolves from Pichu when leveled up with high friendship and evolves into Raichu when exposed to a Thunder Stone.

A male one evolves from a Pichu nicknamed Thunders at an unknown point. He always remains the "second-in-command" in Kimberly's team.
