Sign me up! To me The Goddess will always be the true female power of Eternia. And a proper backstory was right in front of their eyes and they didn't see it. King Grayskull's wife who was caught by the Snake Men and offered to Serpos in sacrifice. In preparation she was turned green with the power of the Snake Men, which gave her, her powers and made her immortal, somehow she got away and managed to take posession of The Staff of Ka. Infected with the Snake Men power she was forever unable to enter Castle Grayskull but protected it from the outside.
