Although her background is never mentioned in the series, the series bible explains she was once a scientist from Earth called Evelyn Powers, who was on board Marlena Glenn's space craft before it crash-landed on Eternia. Evelyn had been insanely jealous of Marlena for being chosen over her to pilot the shuttle. When the ship crashed as the result of an explosion from Skeletor's homeworld of Infinita, Evelyn wound up on Infinita, where the evil powers of that world turned her knowledge of science into sorcery to aid Skeletor. This origin is used in a storybook entitled "New Champions of Eternia" but was unpopular with the show's writers and therefore never alluded to in the cartoon.
