In 1964, an evil counterpart of Wonder Woman from a parallel universe named "Superwoman" was introduced. This Superwoman was a member of the Crime Syndicate of America, a villainous counterpart of the Justice League of America from the parallel world of "Earth-Three" (vs. the Justice League's world of "Earth-One"). Superwoman, like Wonder Woman, was an Amazon, and possessed similar powers of super-strength and flight. Unlike most/all other versions, her golden lasso could change shape into any form she desired, including a giant winged serpent. The Crime Syndicate first came to Earth-One when they felt they were becoming soft without a real challenge to their powers. Ultraman discovered Earth-One after gaining the power to gaze between worlds from exposure to a hunk of Kryptonite. Wonder Woman defeated Superwoman on Earth-1, and Black Canary defeated her on Earth-2 and tied her up in her lasso. Like the other JSA members, Black Canary is transported to Earth-3 when Superwoman accuses her of unfair advantage due to a vibratory force that Power Ring had placed in their bodies. In the showdown on Earth-2 Superwoman was defeated again by Wonder Woman.
