The player controls a Ditto in Pokémon Pokopia.
At the beginning of the game, this Ditto uses its Transform ability to imitate a human. That unusual premise lets the player character perform human-like activities such as building, crafting, gardening, and reshaping the environment while still being a Pokémon at heart.
Ditto is especially suitable for the role because Transform is its defining move in the main Pokémon series. In Pokopia, the transformation is not merely a battle technique: it is central to the game's story and explains why the protagonist can interact with the world in a human-shaped form.
The protagonist is sometimes confused with Pikachu or Eevee because those Pokémon commonly represent the franchise in spin-offs. Pokopia instead makes Ditto the central character, turning its copying ability into the foundation for the game's construction and community-building systems.
