The pale Pikachu with drooping ears in Pokémon Pokopia is called Peakychu.
Peakychu is a special version of Pikachu encountered in Pokopia. The character has pale coloring and drooping ears, making it visually distinct from the standard Pikachu design familiar from the wider Pokémon franchise.
The story gives Peakychu another notable difference: it has lost the ability to generate electricity. That detail makes the character more than a cosmetic variation and ties it to Pokopia’s broader theme of Pokémon living in a damaged, changed environment.
Peakychu is one of several unusual named Pokémon in the game. Other examples include Mosslax, a Snorlax covered in moss, Smearguru, an exceptionally talented Smeargle, and DJ Rotom, a Rotom possessing a stereo system. These characters help give Pokopia’s world its distinctive local history.
