Pokémon Pokopia features 300 Pokémon in its main roster.
The game’s selection draws from Pokémon Generations I through IX, so its creature lineup reaches far beyond the original Kanto species. These Pokémon are encountered through exploration and habitat creation rather than through a traditional sequence of wild battles and gym challenges.
Players build suitable environments to attract different species. Habitats can require particular combinations of landscaping, furniture, plants, or other objects. Once Pokémon arrive, they can help with activities, interact with one another, and teach Ditto moves that alter the world.
The number 300 refers to the Pokémon featured in the game’s roster, not the number of regions represented or the total number in the National Pokédex. Expansion content can add new areas and aquatic-themed Pokémon, so players should distinguish the original roster figure from later downloadable content.
