DC Comics Executive Editor Dan DiDio asked fans for 600 postcards to restore the Wonder Woman comic book to the original numbering, starting at #600. The publisher's office had received 712 postcards by the October 31, 2009 deadline. As a result, the numbering switched to #600 after Wonder Woman #44, in an anniversary issue. Issue #600 featured several stories featuring work from guest creators such as Geoff Johns, George Pérez, Phil Jimenez, and Amanda Conner. The issue featured guest appearances from other female superheroes such as Batwoman, Power Girl, Batgirl, Stargirl and the Question.
Superman begged his fellow heroes to arrest him, and while he was taken to the A.R.G.U.S. facilities, Diana expressed disapproval at Steve’s secret Justice League. Wonder Woman travelled to the Temple of Hephaestus and demanded Hephaestus tell her about what the box really was. Hephaestus answered that the box was not created by the Gods of Olympus and the truth was a mystery even to them. Wonder Woman decided to seek help from the Justice League Dark. Suddenly, the three Justice Leagues converged at the House of Mystery, where the heroes were divided, one side led by Wonder Woman, the other by Batman. Zatanna, having taken Wonder Woman’s side, teleported the group away. Wonder Woman’s group tracked Pandora’s box to Lex Luthor’s prison cell, where Pandora was offering the box to Luthor. Wonder Woman grabbed the box but was overwhelmed by its power.
Would DC Comics introduce Diana's twin brother only to dispatch him so soon? And would he be defeated by Diana, after being manipulated by the Dark Gods? We would wager that Jason sees reason at some point - Diana's greatest superpower is love, compassion, and truth, after all - but anything is possible. Especially with the final splash page promising a war between gods that lives up to the name.
When last we left Wonder Woman #49, the battle brewing ever since DC's METAL cracked open the Multiverse seemed to be reaching its climax. With the Dark Gods playing similar roles to the Greek pantheon, but with all-powerful demands, enslaving humanity, Diana and her twin brother Jason were splitting up to oppose them around the globe. Just as they seemed to knock back their leader, King Best, the Dark Gods launch an assault on Jason.
