What is the Pokopia name of the unique Pikachu character?

The unique Pikachu character in Pokémon Pokopia is named Peakychu.

Peakychu is a special Pokopia design based on Pikachu. It has a pale, ghostly appearance that contrasts with the bright yellow look normally associated with the series mascot. The character reflects the game's world, where Pokémon have adapted to unusual conditions after the disappearance of humans.

The name is not a regional form name from the main Pokémon games. Peakychu is a character introduced for Pokopia, alongside other distinctive designs such as Mosslax and Smearguru. That makes it useful to treat the name as a Pokopia-specific identity rather than as a new species in the standard Pokédex.

Players can confuse Peakychu with a generic pale Pikachu description. The question asks for the character's proper Pokopia name, which is Peakychu.
