On the Isle of Armor, only two Pokemon have brand new Galarian Forms. These two Pokemon are none other than Slowpoke and Slowbro. 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.
When it comes to Galarian Slowbro, however, is much different than Kantonian Slowbro. This is first seen by how it's a Poison/Psychic Type rather than a Water/Psychic Type. Galarian Slowbro also has the brand new ability of Quick Draw. This ability works a lot like the item Quick Claw, which sees slower Pokemon randomly being able to move first in battle rather than going last due to its poor Speed. Galarian Slowbro has a brand new move called Shell Side Arm, which will do either Physical or Special Damage depending on whichever will deal more damage (it can also poison opponents as well).
