The Pikachu who has lost the ability to generate electricity is called Peakychu in Pokémon Pokopia.
Peakychu is one of Pokopia’s special Pokémon characters, whose identity includes a distinctive personal name and a notable problem. Unlike an ordinary Pikachu characterized by electric attacks, Peakychu has lost the ability to generate electricity. That detail gives the character an individual story within the wider rebuilding adventure.
Pokopia uses several playful names to distinguish important Pokémon from their standard species. These names are not new species or official evolutions; they identify particular characters encountered during the game. This makes Peakychu easy to confuse with a fan-made form or with a nickname from another Pokémon product.
The character’s name is also a wordplay variation on Pikachu, while the game’s plot treats the loss of electricity as a meaningful personal setback. Peakychu is therefore the canonical answer for the named Pikachu in Pokopia, not simply “Pikachu,” which identifies the species.
