He took that secret to his grave when he died in 1947. Most superheroes didn’t survive peacetime and those that did were changed forever in 1954, when a psychiatrist named Fredric Wertham published a book called Seduction of the Innocent and testified before a Senate subcommittee investigating the comics. Wertham believed that comics were corrupting American kids, and turning them into juvenile delinquents. He especially disliked Wonder Woman. Bender had written that Wonder Woman comics display “a strikingly advanced concept of femininity and masculinity” and that “women in these stories are placed on an equal footing with men and indulge in the same type of activities.” Wertham found the feminism in Wonder Woman repulsive.
Wonder Woman was taken to Zamaron where the Star Sapphires informed her that a Dark God had taken hold there, too. Diana fought the newly-emerged Karnell, Dark God of Love, who informed Diana that he and his brethren had come from the Dark Multiverse, which the Justice League had recently encountered. When Diana wore the Tenth Metal during the climax of the Justice League's battle with Barbatos, Diana had wished for the gods' return. Though she had meant the Gods of Olympus, the Dark Multiverse's gods were chosen instead, and thus she had unintentionally caused their invasion. Together with the Star Sapphire Corps, Wonder Woman was able to defeat Karnell, who retreated back to Earth. Wonder Woman left the Corps and returned home. In her absence, Jason had united with the Justice League and fought the Dark Gods, who had plunged Earth into chaos. Suddenly, the Dark Gods disappeared, only for them to return with Jason at their side. Jason fought Wonder Woman, but after he led her away from the Dark Gods, he revealed that he was using his armor to channel the power of Dolos, God of Deception, and was in fact deceiving the Dark Gods. Using the wisdom of Athena, Jason developed a plan to convince the Dark Gods to retreat back to their reality. He offered himself, along with the power of the Greek Pantheon, in exchange for the Dark Gods leaving Earth. The Dark Gods accepted the proposal and Diana tearfully said goodbye to her brother, who was taken with them to the Dark Multiverse. The planet was saved and its people returned to normal, but Diana was distraught over the loss of her brother.
In one episode, a newspaper editor named Brown, desperate to discover Wonder Woman’s past, assigns a team of reporters to chase her down; she easily escapes them. Brown, gone half mad, is committed to a hospital. Wonder Woman disguises herself as a nurse and brings him a scroll. “This parchment seems to be the history of that girl you call ‘Wonder Woman’!” she tells him. “A strange, veiled woman left it with me.” Brown leaps out of bed and races back to the city desk, where he cries out, parchment in hand, “Stop the presses! I’ve got the history of Wonder Woman!” But Wonder Woman’s secret history isn’t written on parchment. Instead, it lies buried in boxes and cabinets and drawers, in thousands of documents, housed in libraries, archives and collections spread all over the United States, including the private papers of creator Marston—papers that, before I saw them, had never before been seen by anyone outside of Marston’s family.
