Obsessed Superman fan Dana Dearden dated Jimmy Olsen to get close to Superman, and when that didn't work she stole mystic artifacts which granted her the strength of Hercules, the speed (and flight) of Hermes, the thunderbolts of Zeus, and the sight of Heimdall. Dana donned a green-and-purple uniform, with "Superwoman" written down the leggings, and called herself Superwoman, and tried to get Superman to fall in love with her. He rejected her advances, and Jimmy called her "Obsession". She vanished attempting to help Superman rescue people from a burning ship.
