>>51332919Regional fakes are when the designers wanted to make a regional form but because regional forms are canonically the same species that adapted to a new region and that a mole adapting to become an eel or jellyfish to a mushroom makes no sense, they're canonically they're own unrelated species that just happen to have identical designs. Rfakes are just regular pokemon otherwise.
Paradox forms are powerful, non-evolving pokemon that from the leaks seem to come from a different timeline from the a past/future point in time and will have to actually do with the story/lore of the game.
