>>53452680There's no reliable source in the setting that calls them Paradoxes.
Paradoxes are defined by being something that can't exist, yet still do, because the explanation is yet to be properly revealed.
They can't be time travel, because that causes a paradox, and hence the alleged name of Paradox Pokemon given to them. But because that's impossible, you simply need to find the correct explanation.
That's the imagination theory, of course.
So once that's revealed, their designation can be corrected from Paradox Pokemon to Imagination Pokemon.
