I don't doubt we'll find a lot of Pokemon who are directly analogous to fauna from your world. There's a lot that match my world's.

Allegedly, all Pokemon were made by a creator god - also a Pokemon, of course - so you could make a pretty solid argument that they're all arcane beasts, but they still exist in very physical ways.

If you ever want a hand looking into all of that bullshit some more, I've been doing a lot of research into it. It's useful to know if you want to do any kind of battling, since different types have strengths and weaknesses against other types. Sometimes they can be a bit... obscure.
