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.

In Alola, Pikachu evolves into Alolan Raichu when exposed to a Thunder Stone.

Additionally, Pikachu has four forms: Cosplay Pikachu, Pikachu in a cap, the partner Pikachu, and Gigantamax Pikachu. It can Gigantamax into Gigantamax Pikachu if it has the Gigantamax Factor. Additionally, many other Pikachu variants have appeared in various media.

Cosplay Pikachu, Pikachu in a cap, the partner Pikachu, and Pikachu with the Gigantamax Factor cannot evolve. The starter Pikachu from Pokémon Yellow will refuse to evolve into Raichu unless it is traded and evolved on another save file.
