List of Pokémon with different forms

Some Pokémon of the same species may have different forms due to weather conditions, being from different regions, or other reasons. The difference between forms of a Pokémon species may only be visual, but they can also present different evolution options, availability, types, moves, base stats and weight and height. Most different forms are recorded in the corresponding Pokédex entry under different Pokémon form switches and have separated weight and height records. Shiny switches on Pokédex are form-related, so the Trainer has to acquire different forms of shiny Pokémon to unlock all switches. Some Pokémon forms can be changed through the Form Change mechanic.

Trivia

 * On May, 2018, Alolan forms of Pokémon, originally discovered in the Kanto region, were stated to begin to appear in-game.
 * Some Event Pokémon also count as different forms rather than costumed Pokémon in game, thus they count towards the Special Trades if one of Trainers don't have such Event Pokémon.
 * Shadow Pokémon and Purified Pokémon are also treated as different forms in game.
