'''Pikachu''' is an electrical, yellow mouse and a [[Pokémon (species)|Pokémon]] who is the [[mascot]] of the ''[[Pokémon]]'' franchise. It's recognizable by its lightning bolt-shaped tail and red cheeks that store electricity. [[Ash Ketchum]] of the ''Pokémon'' anime series owns his own Pikachu, who is the most notable Pikachu within the ''Pokémon'' franchise. In the core games, Pikachu evolves into [[Raichu]] if a Thunder Stone is used on it. Since ''[[Pokémon Gold and Silver Versions]]'', Pikachu has a pre-evolved form named [[Pichu]], which evolves if its friendship with its trainer is high enough.
