Pikachu

Pikachu, the iconic Electric-type Mouse Pokémon, was introduced in Generation I alongside the very first Pokémon games, Pokémon Red and Blue. It is the most recognizable Pokémon globally, serving as the franchise's official mascot and Ash Ketchum's loyal companion in the long-running anime series. Pikachu evolves from Pichu when leveled up with high friendship and then into Raichu when exposed to a Thunder Stone. Its natural habitat includes forests and power plants, where it can be found living in small groups. Pikachu primarily feeds on berries and fruits, and its behavior is characterized by its playful yet fiercely protective nature. In the anime, Pikachu is known for its incredible speed and powerful electric attacks, often saving the day for Ash and his friends. Its widespread appeal has cemented its status as a cultural phenomenon, representing the entire Pokémon franchise across various media, including movies, merchandise, and theme parks. Its type matchups generally favor Ground-type Pokémon, which are immune to Electric attacks, while it is strong against Flying and Water types.
