said this interesting theory that may be represented on this new universe:
the “Amazons” of this cinematic DCU will be descendants of those “ancient Kryptonians” who attempted to set up Kryptonian outposts throughout spacedom thousands and thousands of years ago. Furthermore, I say that Wonder Woman will be powered-down, if you will, relative to Superman because these Amazons have evolved and adapted to living on Earth for hundreds of centuries. And since Kryptonians are produced without any “He’n and She’n” – Jor El and Lara excluded – couldn’t this original Kryptonian on Earth have used this reproductive science to create an all-female race? I say yes!
I think this has pretty good potential maybe to be ancient aliens (not necessarily kryptonian) but that pretty much is a good one if you ask me.
