Superwoman

The evil counterpart to Wonder Woman, this Superwoman hails from Earth-Three, a mirror universe where morality is inverted and the Crime Syndicate reigns supreme. She first clashed with the Justice League and Justice Society during a landmark interdimensional team-up in 1964.

Born in the fertile imagination of Gardner Fox and Mike Sekowsky, this Superwoman made her mark on DC's Silver Age when she debuted in Justice League of America #29 in 1964 — stepping onto pages already crackling with the era's boundless ambition. She moves in rarefied company, sharing adventures with heavy-hitters like Green Lantern, Doctor Fate, Johnny Quick, Ultraman, and Power Ring, which tells you something about the scale of the stories she inhabits. Her appearances stretch across nearly five decades and span landmark titles including Crisis on Infinite Earths and Countdown, with at least one collector-recognized key issue to her name. A compact but consequential presence in DC history, she's exactly the kind of character that rewards the curious fan willing to dig into the rich, interconnected tapestry of the DC universe.
