This option is automatically applied in Pokémon Black 2 and White 2. In Pokémon Black and White, the sprite displayed in the Pokédex can be changed after interacting with Cedric Juniper in Mistralton City, even to a Shiny sprite, if it has been encountered. From Generation II to IV, whichever sprite is seen first will be the one displayed in the Pokédex by default e.g., if West Sea Shellos was encountered first its sprite will appear in the Pokédex by default, whereas if East Sea Shellos was encountered first its sprite will. Starting in Pokémon HeartGold and SoulSilver, every official different form has a name given by the Pokédex, with the exceptions of Arceus, Genesect, and Furfrou's alternate forms, which were registered in the Pokédex starting in Pokémon Omega Ruby and Alpha Sapphire. These variations all have differing sprites or models in the games and are recognized by the 'forms' section of the Pokédex. Some Pokémon have official major variations between individuals, known as forms (Japanese: すがた form).
