Alolan Forms are unique regional variants of certain Pokémon introduced in the Pokémon series, specifically in the Pokémon Sun and Pokémon Moon games. These forms feature different appearances, types, and abilities compared to their original versions, reflecting the diverse environments of the Alola region. Each Alolan Form is designed to adapt to the local ecosystem, showcasing how Pokémon can evolve differently based on their surroundings. For example, Sandshrew and Vulpix have Ice-type Alolan Forms, which differ significantly from their original types, adding variety and strategy to gameplay.
