The "Alolan Form" refers to a unique variant of certain Pokémon that were originally introduced in earlier generations. These forms were introduced in the Pokémon Sun and Pokémon Moon games, set in the tropical region of Alola. Alolan Forms often feature different types, appearances, and abilities compared to their original counterparts, adapting to the new environment. Each Alolan Form showcases distinct characteristics that reflect the culture and ecosystem of Alola. For example, Sandshrew becomes an Ice/Steel type, while Meowth takes on a Dark type. This concept adds diversity to gameplay and encourages players to explore different strategies.
