What is the maximum number of Pokémon featured in Pokémon Pokopia's roster?

The Pokémon Pokopia roster contains 300 Pokémon.

These 300 selections span Generations I through IX, giving the game a broad cross-generational cast. The creatures are not included only as collectibles: many help Ditto restore the environment, provide conversation, or teach moves that affect construction and exploration.

Pokopia's roster is closely connected to its habitat system. Pokémon appear when players create surroundings that suit them, such as planting grass beneath a tree or placing a punching bag beside a bench. Individual needs also matter; Hoothoot, for example, prefers darkness.

The roster size should not be mistaken for the number of Pokémon species in the overall franchise or for the number available in any one habitat. It describes the complete selection used by Pokopia. This structure lets the game combine a substantial Pokémon cast with a slower life-simulation format rather than a conventional battle-focused campaign.
