The electrically powerless Pikachu in Pokémon Pokopia is nicknamed Peakychu.
Peakychu is a special Pikachu encountered during Pokopia’s story. Unlike the standard image of Pikachu as a Pokémon capable of producing electricity, this character has lost the ability to generate electricity. The unusual condition makes Peakychu one of the memorable individual Pokémon living in the restored world.
Pokopia gives several Pokémon distinctive identities and personal circumstances. Examples include Mosslax, a Snorlax covered in moss, Smearguru, an especially talented Smeargle, and DJ Rotom, a Rotom possessing a stereo system. These names and traits help the game’s residents feel like characters rather than interchangeable species.
Peakychu is not a separate Pokémon species or an evolution. It is a nickname for a particular Pikachu in Pokopia, so answers such as Pichu or a generic Pikachu do not identify the named character.
