Peakychu is the special Pokémon in Pokémon Pokopia who has lost the ability to generate electricity.
Peakychu is a named variation of Pikachu encountered as Ditto restores habitats. The character's unusual condition is part of Pokopia's collection of distinctive Pokémon, each with a memorable identity or role in the rebuilding story. Peakychu's problem contrasts with Pikachu's familiar association with electrical power.
The name is easy to confuse with Pikachu, Raichu, or Pichu because all four names belong to the same evolutionary family. However, the question asks for the special character's name in Pokopia, not the species normally known for producing electricity. The answer is therefore Peakychu.
Other named characters include Smearguru, a talented Smeargle; Mosslax, a Snorlax covered in moss and plants; Chef Dente, a Greedent; DJ Rotom; and Tinkmaster, a Tinkaton. These characters help give Pokopia's restored world a cast of story-specific personalities.
