Regional variant

Regional variant is a concept introduced in Generation VII. Some kinds of species of Pokémon had immigrated to another region a long time ago from their original region, and this caused them to change their appearance and their type due to the change of their habitat. These Pokémon with different appearance and type, however, only live in the region they migrated.

 * Additionally, Generation VIII is marks the first time for certain Pokemon’s regional variants to have exclusive evolved forms than their normal counterparts. Obstagoon of Galarian Ziazagoon Evolution Line is a prime example.
