realistically, pokopia is a spinoff and is not meant to be canon in any way. but the apocalypse clearly happened a few hundred years after canon so the actual timeline will never get there and there is no proof that it's not a canonical event.
i think the local immortals (L, Floette, and maybe? Volo? Maybe?) are still wandering the ruined planet and are going to stumble upon the pokemon cities and the pokemon will be so excited to see humans. look, they built houses! the humans can come live in the houses if they want!
what a baffling thing to find in your lonely journey through the post-apocalypse.
God now I'm imagining that like. Ok if they tried really hard to get as many people as possible on the space ships did they find records of an immortal wandering around and just track them down and are like "SIR YOU HAVE TO COME TO SPACE"
"I'm immortal this literally can't kill me"
"SIR"
...actually second question: is this "you can't be killed" immortality or "won't die of natural causes but a gun can definitely kill you" immortality
Like yes realistically Pokemon will never acknowledge Pokopia in a mainline game and it would probably suck if they did but it's fun to think about.
I also think if you wanted you can reasonably headcanon around the backstory happening soonish after SWSH/PLZA and not be super contradictory if you wanted to imagine canon characters being involved. Like yeah that's unrealistic when we're talking about climate change but since when has Pokémon put anything on a reasonable time scale?
Also one of the natural disaster is literally lifting Saffron and Celadon into the sky which I have STILL not found an explanation for, so you can probably say "things started going bad REAL quick" without being weirder than the game itself
In my heart pokopia is sort of akin to the post-apocalyptic guzzlord world you can find deep in ultra space in usum, in that this is something that did happen to an earth very much like the ones the mainline games are set in, and in theory is accessible in the same distant way the ultra space worlds are.
Pokopia's premise sort of goes hand-in-hand with finding the ruined version of an alternate futuristic Hau'oli City where most humans fled to space after earth became uninhabitable due to pollution (implied to be caused by some disaster with the power plants), leaving behind only a few pokemon and people like the guzzlord and the guy who didn't have the heart to leave it alone. They're certainly different scenarios with different long-term outcomes, but I could see it existing out there in much the same way, just a long and unlikely warp ride away.
So like all of that is to say that I'd like to think it's possible that one day the gen 7 protagonist shows up out of nowhere, pokes around for a few hours, and then goes back through some awful hole in existence and is never seen again.
