>>43955621I think it's pretty unlikely that there will be more Galarian forms in the Crown Tundra other than Slowking and the birds, but I can say with confidence that any potential Galarian forms must be within the Pokemon whose blank entries were removed in the Isle of Armor, see pic related (source:

GF has yet to add a Galarian form and not add its original form in alongside it, except for Version 1.1.0 where Galarian Slowpoke was added, but it was not a full evolution line. When Galarian Slowbro was added in the Isle of Armor, the original forms of Slowpoke, Slowbro, and Slowking were added too. Thus, the blank entry for a Pokemon with a Galarian form will have been scrubbed since the normal form will return in kind. Pic related has an extremely small selection, especially when looking across 3 generations: Gen 2 adds literally only babymons and legendaries, Gens 6 and 7 don't have many mons to add in the first place (that aren't UBs), and Gen 4 likewise only adds Spiritomb and the Gible line, which is confirmed not getting a Galarian form (Garchomp shown in trailer) Further, (perhaps because of the abundance of Unovamons in base Galar and IoA) Gen 5 is also rather sparse. So there aren't even 3 gens to look across.
