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.
The New 52 universe does not have a "Diana Prince" identity as stated in an interview by series writer Brian Azzarello. However, when she and Superman began dating, for her civilian identity she used the Diana Prince alias whenever she was around Clark Kent; such as when she introduced herself to Lois Lane at Lois's housewarming party under that name.
Wonder Woman made her debut in All-Star Comics at the end of 1941 and on the cover of a new comic book, Sensation Comics, at the beginning of 1942, drawn by an artist named Harry G. Peter. She wore a golden tiara, a red bustier, blue underpants and knee-high, red leather boots. She was a little slinky; she was very kinky. She’d left Paradise to fight fascism with feminism, in “America, the last citadel of democracy, and of equal rights for women!”

Steve Trevor's secretary who befriends Diana. Describing her character, Davis said, "She's a woman in a man's world and so being heard and seen aren't the easiest things, but it kind of doesn't deter her", adding, "Etta is unapologetically herself and I think that that's the thing that has drawn me to her the most". When asked if she was previously familiar with the character, Davis responded, "No. I wasn't. It took me a while to know that I was auditioning for Etta because even when I found out it was Wonder Woman, I still had no idea what the role was. It took a little while then I Googled the character". On Etta Candy's relationship with Steve Trevor, Davis said, "One of the great things that Etta gets to work with Steve Trevor is because Steve is not your typical man, in that he does entrust her with things that in 1918 probably wouldn't have been entrusted to a secretary of somebody who is quite important", further explaining, "So I think that [Trevor] needs her just as much as she needs that because now she's been given responsibility that she wouldn't have normally be given before, and equally he has somebody who could probably fly under the radar a bit. So he can trust the person who no one's really looking at".
Although she initially forbids Diana to be trained as a warrior, Hippolyta reluctantly agrees to let General Antiope, Hippolyta's sister and Diana's aunt, train her, only more rigorously than any other warrior. In 1918, Diana, now a young woman, rescues US pilot Captain Steve Trevor when his plane crashes off the Themysciran coast. The island is soon invaded by German soldiers that had been pursuing Trevor. The Amazons kill the crew, but Antiope sacrifices herself to save Diana. Steve is interrogated with the Lasso of Hestia and reveals that a great war is consuming the outside world and that he is an Allied spy. He has stolen a notebook of the chief chemist Dr. Isabel Maru, who is attempting to engineer a deadlier form of mustard gas under the orders of General Erich Ludendorff from a weapon facility in the Ottoman Empire. Believing Ares to be responsible for the war, Diana arms herself with the "Godkiller" sword, the lasso, and armor before leaving Themyscira with Steve to locate and stop Ares for good.
As the soldiers landed on the shore and began to open fire, several archers leaped from the cliffs. Diana watched, horrified, as a bullet fired from one of the German soldiers hit an archer, killing her almost instantly. Amazonian cavalry stormed the beach, engaging the soldiers and quickly overwhelming them. Though Trevor told her to stay back as he fought one of the German soldiers, Diana picked up a sword from a fallen Amazon and easily dispatched a soldier.
While Superman watched out for Zod, Diana visited the deserted Themyscira to speak to her mother, still a clay statue. In her absence, a demon from Tartarus had escaped from its prison and roamed free on the island. Wonder Woman destroyed the creature and sealed the gates to Tartarus with her lasso. Leaving the island, she received word from Batman that Superman was engaging Zod and Faora in battle. Reaching Superman’s side, Wonder Woman steadily overwhelmed Faora until Zod threatened Superman’s life. Wonder Woman was forced to let the criminals go.
