The protagonist of Pokémon Pokopia is a Ditto.
Ditto is a Pokémon famous for its ability to transform into other forms. Pokopia uses that established characteristic as the foundation for its story: the player’s Ditto assumes a human appearance and takes on the role of a helper in a world abandoned by humans.
This makes the protagonist both a Pokémon and a human-like avatar. The distinction matters because the game’s activities are designed around cooperation with Pokémon rather than controlling a conventional trainer. Ditto gathers resources, builds structures, creates habitats, and uses abilities learned from Pokémon to change the environment.
The story begins after Ditto discovers an old Pokédex belonging to its trainer. It then encounters Professor Tangrowth and becomes involved in restoring the world’s damaged habitats. Although Ditto’s appearance can be customized, its species remains Ditto. The human form is a transformation used by the character, not a separate human protagonist.
