In Pokémon Pokopia, the post-apocalyptic setting is the Kanto region.
The game presents Kanto after humans have abandoned the world and Pokémon habitats have become difficult to live in. Instead of visiting familiar towns in their usual condition, players explore damaged landscapes and gradually restore them through building, crafting, and habitat creation.
This setting connects Pokopia to one of Pokémon’s best-known regions while giving it a different tone from the main role-playing games. The story includes locations inspired by the region’s established identity, but the emphasis is on rebuilding communities rather than collecting badges or winning battles.
The ruined environment also explains why Ditto is needed. As the player character restores habitats, more Pokémon return and begin helping with the recovery. Kanto is therefore more than a backdrop: it is the world being repaired. The game’s plot eventually reveals that humanity left Earth after unexplained phenomena made the landscape increasingly hostile to life.
