When the Pokemon Company first revealed that they would be moving forward with Pokemon Sword & Shield DLC Packages instead of sequel games, it was shown that the Slowpoke Evolution Chain (which includes Slowpoke, Slowbro and Slowking) would be receiving Galarian Forms. By purchasing the Expansion Pass (which includes both DLC Packages) from the Nintendo Shop, players can activate an event within Pokemon Sword & Shield that will see them be able to capture Galarian Slowpoke. From there, players can evolve Galarian Slowpoke into Galarian Slowbro when exploring The Isle of Armor (while being able to evolve Galarian Slowpoke into Galarian Slowking within The Crown Tundra).
Galarian Slowpoke is a lot like Kantonian Slowpoke in that all of its Base Stats remain the same. However, instead of being a dual Water/Psychic Type like its Kantonian Counterpart, Galarian Slowpoke is simply a pure Psychic Type. Galarian Slowpoke can also have the ability of Gluttony instead of Oblivious, while keeping its secondary and hidden Abilities of Own Tempo and Regenerator, respectively.
Galarian Slowpoke will be able to evolve into Galarian Slowbro by way of a special Evolutionary Item found only within The Isle of Armor. Galarian Slowbro is much different than Kantonian Slowbro, seen first by being a Poison/Psychic Type rather than a Water/Psychic Type. Galarian Slowbro will also have the brand new ability know as Quick Draw (though not much was revealed about this ability initially).
