Maybe some Looker DLC. It'd be quite the twist if Looker turned out to be from the past.
If Looker were to appear in this game, I think it'd make the msot sense if he was brought to the past via the space-time portal, like the player character and Ingo. That being said, the nature of these "hints," is never that direct. Rather, if we're to follow those breadcrumbs, it most likely means there are characters planned who have some connection to Looker and Palmer, or one character connected to both, not Looker and Palmer directly.
Nevertheless, that does bring up an idea. Since I'm sure the characters who wound up in Hisui from the present will make their way back, this could be an in-universe way to explain why these Hisuian species and regional forms are suddenly appearing in the present: these characters, particularly the player character, brought them back with them. (I'm thinking about how the Fossil Pokémon are present in the wild in Crown Tundra--the game didn't immediately explain why they were there, but the Pokédex entry for one of them spoke of how they were revived from fossils, then released in the wild and wound up there.)
I just want see if update allow will allow more older so i can hopefully transfer greninja from pokemon home. I know Froakie wasn't from SInnoh but leaving a ninja themed pokemon out of a a game that is heavily inspired by ancient japan? It's just a weird decision that it's not a wild encounter.
Indeed. In the Cobalt Coastland chapter you're attacked by both Irida's Glaceon and a Eevee (Don't know if it was a wild eevee and i tried to catch it after Glaceon was ko'd) These 2x1 trainer battles are annoying when they happen without warning.
Space-Time Distortions will throw you up into battles where you're outnumbered up to 4-to-1. Why the player character doesn't throw out Pokémon to equal theirs I don't know, since Pokémon battling hadn't been codified in Hisui yet.
I did think Froakie was a shoe-in, but I don't know how big of a cultural concept the ninja was in 19th-century-to-early-20th-century Hokkaido. You can see in Hisuian Samurott's Pokédex entry that there is no mention of samurai at all, for instance, just that it's a relentless warrior. That is, this is not the Pokémon counterpart to "ancient Japan," but "Industrial Revolution Hokkaido." The new Pokémon who appear are based on culture from that time and place. For instance, Ursaluna is based on a species of bear from Hokkaido that went extinct. There were vicious bear attacks through the 1910s in Hokkaido, so hunters exterminated them to extinction (with I think just one species remaining, which is still viewed with dread and "kill it now before it kills you"). Meanwhile, Professor Laventon's choice of Rowlet, Cyndaquil, and Oshawott are because owls, weasels, and otters are of special importance as guardian spirits in Ainu mythology.
