Region-based Evolution
Region-based Evolution refers to Pokémon that evolve in a certain region in the Pokémon games. This method of Evolution was introduced in Generation VII.
All known region-based Evolutions are branched Evolutions, in which a Pokémon evolves into a regional form of a previously introduced Pokémon.
List of region-based Evolutions
In the table below, the "Introduced in Generation <number>" label refers to the generation when the region-based Evolution was introduced. The branched Evolutions outside those regions were introduced in earlier generations.

In the core series games
A region-based Evolution is triggered once the Pokémon levels up in a certain region, either at the end of a Pokémon battle or by the use of a Rare Candy.
In Pokémon Ultra Sun and Ultra Moon, if a Pikachu, Cubone, or Exeggcute evolves in Ultra Space, it will become a Kantonian Raichu, Marowak, or Exeggutor rather than their respective Alolan forms. They still evolve into their Kantonian forms even in the Ultra Ruin, which is a parallel version of Alola identified as part of the Ultra Space.
In the TCG
In the Pokémon Trading Card Game, those evolved Pokémon are simply available as regular Evolutions with no additional requirement. For instance, a Pikachu card can equally evolve into a Raichu or Alolan Raichu card.
Trivia
- Cubone is the only Pokémon that does not share any type with its region-based Evolution.
- Dartrix is the only Pokémon whose original Evolution and region-based Evolution are triggered under different circumstances other than the current region. Specifically, it evolves into Decidueye or Hisuian Decidueye at different levels.
