Pokémon Pokopia includes Pokémon from how many generations?

Pokémon Pokopia includes Pokémon from nine generations of the series.

The game's roster draws from Generations I through IX, giving the habitat-building adventure a broad mixture of familiar species. This range reaches from the original Kanto Pokémon to species introduced in the Paldea-era games.

The total is a generation count, not the number of Pokémon available in the game. A generation can contain many species, and Pokopia selects a particular group for its environments and story. This distinction matters because the game is designed around habitats rather than serving as a complete Pokédex.

The selected Pokémon also support the game's simulation systems. Different species prefer different surroundings, and players must create suitable habitats to attract them. Consequently, the roster is connected to construction and environmental design, not simply to collecting or battling.
