Pokémon Forms are variations between individual Pokémon, these variations may be different in types, ability, stats, or learnsets sometimes forms are purely aesthetic. Pokémon Forms are first introduced in Generation II with Unown but purely aesthetic. In Generation III some Pokémon forms begin to bear differences in types, ability, stats, or learnsets with Castform (weathers effecting its typing) and Deoxys (stats and learnsets variations among forms however Deoxys' forms are version locked until Generation IV).
