Attempting to develop a female sidekick for Booster Gold, his corporation hires then S.T.A.R. Labs scientist Jack Soo to create a supersuit for her to wear; the resulting suit infused with magnetic energy which the wearer could use to "key" onto a metallic object to attract or repel the object or the wearer, mimicking the abilities of super-strength and flight. The costume was then dubbed with the name that Booster's corporation had at the time, Goldstar.
