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.
