List of Pokémon with form differences (GO)
In Pokémon GO, several Pokémon have various forms, similar to those in the core series, but affected by completely different mechanics. All forms in GO except for Shaymin, Furfrou, and Hoopa are determined at the time of capture and cannot be changed. Although every species has one Pokédex entry each, a Pokémon is considered different from any of its alternate forms; this means that even if a player has one form of the Pokémon species registered in the Pokédex, an alternate form will still appear as a silhouette in the Nearby screen, and receiving one in a trade will be considered a Special Trade.
Regional forms
Regional forms were first introduced to Pokémon GO around the time Pokémon Ultra Sun and Ultra Moon was officially announced. Some species appear in the wild, while others are exclusive to 7 km Eggs, raids, and later, Field Research (with the exception of limited-time events). Galarian Weezing was introduced on November 16, 2019 in raids to celebrate the release of Pokémon Sword and Shield. Hisuian Voltorb was introduced on January 30, 2022 in the wild and Special Research to celebrate the release of Pokémon Legends: Arceus.
