It's a little alarming that they've apparently gone extinct since the Hisui period
but agreed, very cool!
Maybe if they keep the storyteller narrative they have in the trailers, like the reader is one of Rowan's assistants who finds these old reports and decides to investigate them, and upon discovering the these alt evolutions & forms sets to work to trigger them again, find where they went, or reverse engineer them (I'm sure if you breed a female Growlithe/Arcanine with Rockruff/Lycanroc enough times one of their children will be a Hisuian Growlithe, that's just science!),
Don't tempt fate like that, otherwise the reveal of Bug/Flying Hisuian Mandibuzz is practically guaranteed
Joke is on you cause it'll be normal flying
Well if we go by tradition of Regional Variants trying to flip a Pokemon's concept on its head, I'd say a Hisuian Mandibuzz would be Fairy/Flying and instead of decorating its nest with bones & skulls it uses colorful feathers (or it's naturally colorful so it uses white feathers taken from Hisuian Braviary to better disguise itself and Hisuian Vullaby).
I look at Wyrdeer and Basculegion and i do not see "traditional cross-gen evolutions" I see "it's regional evolutions, again"
They underlined the connection to the Hisui region specifically in how they evolve and were shown alongside the two more "traditional" regional variants.
Wouldn't surprise me if there's specifically Hisui Stantler and Hisui Basculin like how Sirfetch'd comes from Galarian Farfetch'd
But as counterpoint, Galarian Weezing evolves from regular Weezing (same as how A-marowak and A-raichu evolve from regular Kanto forms), so I think both options are possible
Honestly, I more see there being a Hisuian Stantler since we don't have a regional evo that evolves from a normal form. And while they can certainly do one, I think GF hasn't because they're afraid of upsetting some fans you like the normal Pokemon ending where it did. So they make a regional variant of the Pokemon and give it a regional evo to solve that problem. In addition Wyrdeer sounds like its a Special Attacker now so would likely flip Hisuian Stantler's Attack with its Special Attack (going from 73/95/62/85/65/85//465 to 73/85/62/95/65/85//465).
However, we do have a regional form which kept its original form's prevo, so I'm going out on a limb to say that we'll have normal Rufflet evolve into Hisuian Braviary. It's also mentioned Hisuian Braviary is still a Physical Attacker so there's no need to change Rufflet's stats.
While we're at it, I think we'll get a Husuian Basculin which is a singular Pokemon that shares traits from the two other Basculin and purple/magenta colored (and no doubt they'll say that it's the true form of Basculin and the ones in Unova are distant relatives who inner fought and thus diverged).
And another risky bet, I think Hisuian Growlithe is NOT going to evolve into Hisuian Arcanine but rather a new regional evo. With Hisuian Growlithe looking even MORE like a Shishi statue, I think the direction is an even more extravagant statue beast something like a Qilin or Pixiu (maybe even change from Stone/Fire to Stone/Dragon).
Hypothetical Basculin-H could easily just have some slightly different markings on it, or have an entirely different back end that's replaced by the ghostly cloud-like shape upon evolution.
Basculegion only has the ghostly wisps because the spirit of its lost kin are now possessing it. Basculin-H would likely just be pure Water-type and resemble a combination of both Basculin, once again probably because they'll try selling us its the original Basculin species.
Also now that we have regional variants/evolutions confirmed I'm like 99.9% sure that there are either going to be Hisuian forms of Decidueye, Typhlosion, and Samurott or Rowlet, Cyndaquil, and Oshawott will get new branched evolutions. Just seems to line up too perfectly IMO
Hmm... I'm going to say no. Why? Because they're not native to Hisui. Remember, the Oshawott, Cyndaquil, and Rowlet were brought over from their region or origin from Professor Laventon's world travels.
Is it just me, or do the two new battle styles seem to be inspired by Urshifu's two forms? We have a Strong style that focuses on defeating opponents in a single hit (Single Strike style) and an Agile style that makes your moves rapid-fire (Rapid Strike style). Maybe Kubfu and Urshifu have something to do with Hisui? Kubfu's bio on the SWSH site does say that it is not native to Galar and was originally from a "mountanious region"...
When I heard of the two forms I did think of Urshifu. I was wondering if maybe they would make some kind of connection, but then I thought having Kubfu in Legends would kind of downplay its importance in the Isle of Armor DLC so shrugged it off. But, then remembering that the Crown Tundra have the new Regi forms which could link them to BDSP, maybe it WAS intentional and they planned for both DLCs to gave a connection to a different Sinnoh game: Isle of Armor to Legends & Crown Tundra to BDSP.
