Pokémon Pokopia calls its Pikachu character that cannot generate electricity Peakychu.
Peakychu is one of Pokopia's special Pokémon characters. Unlike the ordinary image of Pikachu as an Electric-type Pokémon able to produce electricity, this character has lost that ability. The unusual condition gives the character a distinct role in Pokopia's story and community.
The name is a wordplay variation on Pikachu, which makes it easy to overlook or misremember. It is not a new Pokémon species or an alternate regional form listed in the main Pokédex. It is a named individual character within Pokopia's setting.
Other special residents also receive descriptive names, including Professor Tangrowth, Mosslax, Chef Dente, DJ Rotom, Smearguru, and Tinkmaster. Those names identify particular characters and should not be confused with standard species names or evolution stages.
