The unusual Pikachu encountered in Pokémon Pokopia is named Peakychu.
Peakychu is one of Pokopia’s special Pokémon characters. Unlike an ordinary Pikachu, Peakychu has lost the ability to generate electricity. The character is encountered as Ditto and Professor Tangrowth restore habitats and investigate the abandoned world.
Pokopia gives several familiar species distinctive identities and circumstances. Mosslax is a Snorlax covered by moss and plants after sleeping for a very long time, while Smearguru is an exceptionally talented Smeargle painter. These names and traits are part of Pokopia’s story rather than standard species names used throughout the Pokémon franchise.
Peakychu can therefore be confused with a nickname, a regional form, or a misspelling of Pikachu. In the game’s narrative, it is the specific name of the electricity-lacking Pikachu character. The spelling begins with “Peak,” making it distinct from the ordinary species name.
