Peakychu is the Pokémon that loses its ability to generate electricity in Pokémon Pokopia.
Peakychu is a special Pikachu encountered during the story. Unlike an ordinary Pikachu, this character has lost the ability to produce electricity, giving it a distinct personal problem within the game’s wider restoration narrative.
The character is one of several named or unusual Pokémon connected to the recovering world. Other examples include Smearguru, a talented Smeargle; Chef Dente, a Greedent with a culinary background; DJ Rotom, which has possessed a stereo; and Tinkmaster, a Tinkaton adapted to using tools.
Peakychu is easy to confuse with Pikachu because Peakychu is explicitly a Pikachu who has lost its electrical power. The question asks for the character’s special name, not the species name. Therefore, “Pikachu” describes what Peakychu is, while “Peakychu” is the single named answer used in Pokopia’s story.
