Pikachu Pokémon Red & Green Images

Pikachu (Japanese: ピカチュウ Pikachu) is an Electric-type Pokémon. It evolves from Pichu when leveled up with high friendship and evolves into Raichu when exposed to a Thunderstone.

Pikachu is popularly known as the mascot of the Pokémon franchise and a major representative of Nintendo's collective mascots. It is also the version mascot of Pokémon Yellow, where it is the only starter Pokémon in that game. It has also made numerous appearances on the boxes of spin-off titles.

Pikachu is a short, chubby, rodent-like Pokémon with yellow fur all over its body. Pikachu's ears are long and come to a point with black tips. It has a small mouth, which resembles a sideways 3, it has black eyes and two red circles on its cheeks. Its forearms are short and somewhat stubby, with 5 digits on each "hand" and its feet have three digits. It has two brown stripes on its back, and its tail is in the shape of Zigzag-styled lightning bolt, with a patch of brown fur at the base of the tail. Although it is technically a quadruped, on multiple occasions it has been shown to be able to stand and walk upright on its hind legs. Besides its evolution and pre-evolution, it may be related to Plusle, Minun, Pachirisu and/or Emolga due to their many physical similarities.
