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 , , or evolves in Ultra Space, it will become a Kantonian , , or 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 card can equally evolve into a or Alolan card.
==Trivia==
* 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 or Decidueye at different levels.
===Pokémon types===
* All region-based Evolutions have two types.
** is the only Pokémon that does not share any type with its region-based Evolution. Specifically, Cubone is while is .
** With the exception of Cubone, if the pre-Evolution had a single type, the region-based Evolution keeps this type and gains a new one. For instance, is while is .
** If the pre-Evolution had two types, the region-based Evolution keeps one of them while replacing the other type with another. For instance, is while is .
* is the type shared by most region-based Evolutions, with 3 Pokémon having it as part of their type combinations: (), (), and Hisuian ().
** is the only type combination shared by two region-based Evolutions.
* Out of all Pokémon with region-based Evolutions, Dartrix is the only one that does not have the same type combination as its original Evolution. Specifically, Dartrix is while Decidueye is .
