Pokémon Pokopia’s main roster represents 300 Pokémon.
The roster is selected from Generations I through IX, so it is a cross-generational collection rather than a regional Pokédex limited to one era. The game uses these Pokémon primarily as potential residents, helpers, and participants in the player’s restored habitats.
This number matters because Pokopia’s design is built around relationships between Pokémon and environments. Different creatures can require different habitat features before they appear, turning the roster into part of the building system. Players are not simply encountering species in random battles; they are shaping spaces that suit Pokémon with distinct preferences.
The total can be confused with numbers associated with other Pokémon games, including National Pokédex counts or the size of a particular generation. It also does not mean that every Pokémon species appears. The documented Pokopia roster contains 300 selected Pokémon, with later content able to expand the game’s activities and available aquatic-themed creatures.
