The base game of Pokémon Pokopia includes 300 Pokémon species.
The selection spans Pokémon from Generations I through IX, giving Pokopia a broad cross-generational roster rather than focusing on one regional Pokédex. Players encounter these Pokémon while restoring habitats and creating environments suited to different species.
The number refers to Pokémon included in the game, not the number of habitats, moves, or available cosmetic variations. That distinction matters because Pokopia’s central progression is environmental: building and furnishing suitable spaces attracts more Pokémon over time.
Pokopia’s roster is also separate from the complete National Pokédex. It is a curated selection designed for the game’s social-simulation and sandbox structure. Later downloadable content adds further Pokémon and areas, so references to 300 generally describe the original game’s roster rather than every Pokémon available after expansions.
