What species is Peakychu in Pokémon Pokopia?

Peakychu is a Pikachu in Pokémon Pokopia.

Peakychu is one of the game's specially characterized Pokémon. The story describes this Pikachu as having lost the ability to generate electricity, giving the familiar species a distinctive personal problem within Pokopia's post-apocalyptic setting.

The name is a variation on Pikachu's name, but Peakychu is not presented as a separate species or official evolution. It is an individual Pikachu with a special identity and story role. That distinction matters because Pokémon games often use nicknames, titles, or altered names for individual characters.

Peakychu appears alongside other named characters connected to the game's restoration story. These include Smearguru, an unusually talented Smeargle, Mosslax, a Snorlax covered in plant growth, and Chef Dente, a Greedent associated with cooking. Peakychu's specific trait is the loss of electrical power, not a change into Raichu or Pichu.
