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 IV.
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 at the end of a Pokémon battle or by the use of a Rare Candy in a certain region.
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.
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.
