Peakychu is the Pokopia character who is a Pikachu without the ability to generate electricity.
Peakychu is one of the special Pokémon Ditto encounters while restoring habitats. The character’s defining problem is the loss of Pikachu’s familiar electrical power, which gives this version of the species a different story from an ordinary Pikachu.
The name is a character name used within Pokopia, not a separate species or a new evolution. That distinction matters because Peakychu remains a Pikachu in the game’s story and is presented as an individual with an unusual condition.
Other named characters include Smearguru, a talented Smeargle; Mosslax, a Snorlax covered in vegetation; DJ Rotom; Chef Dente; and Tinkmaster. These names describe individual Pokopia characters and should not be confused with official Pokémon species names.
