In Pokémon Vortex, region forms of certain Pokémon can be obtained. To be able to encounter or evolve a regular Pokémon into an Alolan form, a player must be within the Alola region of Sidequests. When you continue beyond this point and begin a new region, Alolan forms will no longer be obtainable until sidequests have been reset and completed up to Alola again.
There are 18 Pokémon connected to this region.
