Which Pokémon Pokopia character is a Ditto imitating?

In Pokémon Pokopia, Ditto is imitating a human.

This transformation explains the game’s central visual and narrative idea. The playable Ditto has a humanoid appearance and uses that form while exploring the abandoned landscape, crafting objects, and helping Pokémon rebuild suitable habitats.

The story says that Ditto finds its trainer’s old Pokédex and assumes a form based on that trainer. This detail connects the protagonist’s human appearance to the world’s former human inhabitants, who have disappeared from the ruined Kanto region.

Ditto’s imitation should not be confused with a permanent evolution or a new Pokémon species. Ditto remains Ditto, using its established transformation ability as the foundation for the game’s mechanics. The player can also customize aspects of the human-like appearance, including hair, skin color, and clothing.
