One Piece: the Pokémon Kingdom of Beasts

In the age of great pirates, countless people rushed to the sea. The boy who gained the power of Arceus joined this world and became a member of the beasts. When the power of Pokémon merges with the fruit to form new phantom fruits, fire-breathing dragons, fossil pterosaurs, and phantoms representing Pokémon fill the sea. For yourself and for the people you cherish, build high walls, accumulate food, and finally overthrow the world. It all started when Kaido retrieved the first stone tablet.
