The special Pikachu character in Pokémon Pokopia is called Peakychu.
Peakychu is a distinctive version of Pikachu encountered in the game's story. According to the game's character descriptions, this Pikachu has lost the ability to generate electricity, giving it a problem that fits Pokopia's broader theme of helping Pokémon recover in a damaged world.
The name is easy to confuse with Pikachu's many official forms, costumes, and regional appearances across the wider Pokémon franchise. Peakychu is a character name used specifically within Pokopia's cast, rather than a standard evolution or a new species replacing Pikachu.
Pikachu remains one of Pokémon's central mascots, but Pokopia gives familiar species unusual identities and circumstances. Peakychu's lost electrical ability is therefore part of the game's narrative world and helps distinguish this character from an ordinary Pikachu encountered elsewhere.
