What category does Pikachu have in the Pokémon Pokédex?

Pikachu has the Pokédex category “Mouse Pokémon.”

Pikachu is an Electric-type species and the best-known mascot of the Pokémon franchise. Its design features yellow fur, red cheek pouches that store electricity, pointed ears, and a tail shaped like a lightning bolt.

The category is a Pokédex classification, not the Pokémon's elemental type. This distinction causes a common mix-up: Pikachu is an Electric-type Pokémon, but its species category is Mouse Pokémon. Its Pokédex entries also describe it as a creature capable of storing and discharging electricity through its cheeks.

Pikachu first appeared in Pokémon Red and Green and became even more prominent through the animated series, where it was Ash Ketchum's main partner. Pikachu's popularity led to its role in Pokémon Yellow, several spin-off games, merchandise, and the “Detective Pikachu” films. Its category has remained one of the clearest links between its visual design and its original Pokédex identity.
