What region is arceus in?

1 Answer

Arceus is thought to have created the Sinnoh region and possibly the entire Pokémon world, the lake guardians Uxie, Azelf, and Mesprit; and the creation trio Dialga, Palkia, and Giratina. Because of this, Arceus is thought to be one of the most long-lived of all Pokémon species.
