What species classification does Pikachu have in the Pokémon Pokédex?

Pikachu has the Pokédex species classification “Mouse Pokémon.”

Pikachu is an Electric-type Pokémon and is identified by its yellow fur, pointed ears, red cheek pouches, and lightning-bolt-shaped tail. Its classification describes its creature design, while Electric is its elemental type.

The distinction matters because species classifications and types are different pieces of Pokémon information. Pikachu is not classified as an “Electric Pokémon” in the species field; Electric is its type. Pikachu's Pokédex number in the original National Pokédex is 025.

Pikachu became the franchise mascot through its prominent role in the animated series, where it accompanies Ash. The character was designed by Atsuko Nishida, and Pikachu's name combines Japanese words associated with sparkling sounds and squeaking.
