Pikachu is a yellow, mouse-like creature with electrical abilities. Pikachu evolves from another pokémon, Pichu, and Pikachu himself can later evolve into Raichu. Pikachu often live in houses, forests, plains, sometimes mountains and islands, and abandoned power plants around the world. As an electric-type Pokémon, Pikachu can store electricity in its cheeks and attack with it when needed.
