From Bulbapedia, the community-driven Pokémon encyclopedia.
Some Pokémon with form differences can change between their forms (e.g. Castform), while others are fixed and can not be changed (e.g. Unown).
In [[Pokémon Sun and Moon]], [[regional form]] Pokémon were introduced. These Pokémon have adapted specifically for the environment of that region and have different appearances, types and abilities to Pokémon of the same species found elsewhere. The ones found in [[Alola]] are known as Alolan Forms while the ones found in [[Galar]] are known as Galarian Forms.
