Pokémon Pokopia includes 300 Pokémon in its main selection.
Those Pokémon are drawn from Generations I through IX, giving the game a broad cross-section of species from across the franchise. Rather than treating every Pokémon as a battle roster, Pokopia places them into habitats and communities that players help restore.
Different Pokémon prefer different environments or arrangements. Players may need to plant grass, place objects, provide darkness, or create other suitable conditions before particular Pokémon appear. This turns the Pokédex into a guide for world-building as much as a collection checklist.
The number 300 can be confused with the total number of Pokémon in the wider franchise, which is much larger. It also refers to the game’s available Pokémon selection, not necessarily a claim that every form or variation is counted in the same way. Later aquatic content expanded the game’s world, but the headline selection figure for Pokopia is 300.
