She was hinted at, but never elaborated on. She was shown as the one who ate the fruit of the Shinju, getting chakra and her action is what caused the Shinju to become the Ten-Tails.

Had that been it, that would have been fine. Because then her action would have been the framing device for Hagoromo to become the Sage of the Six Paths and the history of ninja. Instead, with just about no warning at all, she was a evil selfish god. And yes I'm aware that in universe this was the point as Black Zetsu all but wiped her out from history, but from the outside looking in, that just comes across as a lazy excuse to not have to explain a random super villain appearing out of nowhere.
