A fight broke out among the heroes for possession of the box and was only ended when John Constantine took the box, being the only one capable of doing so without being corrupted. Zatanna and Constantine took the box to the temple of Hephaestus, where the three Justice Leagues had converged again. After yet another battle between heroes, the box went dormant and the Justice Leagues discovered a Kryptonite sliver in Superman’s nervous system, placed there by the Atomica, a traitor working for the Outsider, leader of the Secret Society. Then, the Outsider used the box to open a path across universes, allowing the Crime Syndicate to enter the Justice Leagues' world.
The sister of Hippolyta, general of the Amazonian army, Diana's aunt and mentor. On being cast for the film, Wright said, "It's two-fold because when Patty Jenkins called me, the director, it was a three-minute long conversation. She said, 'I'm doing a movie about Wonder Woman. Do you want to be her trainer?' And I was like, 'Yes. Of course.' And the general of the Amazonian army. That was pretty cool." Describing her character mentoring and training Diana to be a warrior, Wright said, "It's a sixth sense that it is coming and I think that's also in the mythological story behind Antiope and Queen Hippolyta. They know it's coming and it's her duty as the aunt to her young niece to make sure she is the fiercest warrior of all time." On the Amazons fighting style, Wright said, "It's hand combat. Yes, swords and knives and arrows, but the precision that they have, right, as these warrior women; it's so nice to see that disparity between what we had in the day of just raw fighting materials and the guns and how easy that is in comparison." The message of the film, Wright stated, "is not just female empowerment. It's about love and justice. That's what the film's about. And what a great message to spread to our little ones." Commenting about training for the film, Wright said, "The most empowering was to get into that physical shape. So we were doing horseback riding training, weight training, martial arts, and 2,000 to 3,000 calories a day".
Gaines was hugely relieved, at least until September 1943, when a letter arrived from John D. Jacobs, a U.S. Army staff sergeant in the 291st Infantry, stationed at Fort Leonard Wood, Missouri. “I am one of those odd, perhaps unfortunate men who derive an extreme erotic pleasure from the mere thought of a beautiful girl, chained or bound, or masked, or wearing extreme high-heels or high-laced boots,—in fact, any sort of constriction or strain whatsoever,” Jacobs wrote. He wanted to know whether the author of Wonder Woman himself had in his possession any of the items depicted in the stories, “the leather mask, or the wide iron collar from Tibet, or the Greek ankle manacle? Or do you just ‘dream up’ these things?”
The success of the superhero television series Supergirl informed the marketing and promotion strategy used for Wonder Woman. According to Time Warner chief marketing officer Kristen O'Hara, they wanted to approach the Wonder Woman marketing campaign in a light manner, similar to how they did with Supergirl. O'Hara elaborated that the modest campaign route they took for Supergirl aided in establishing a large central fanbase among women well in advance of the series, which reportedly generated 5 million female superhero fans in one week. They were then able to model over time, and grow that audience leading up to the 15-months-later release of Wonder Woman. Though neither the film nor the series are aimed exclusively at women, the latter's campaign gave them their first opportunity to begin collecting data about female superhero fans. In May 2017, a promo for Wonder Woman was released during the season finale of Supergirl, featuring a remix of the song "These Boots Are Made for Walkin'" and Supergirl (Melissa Benoist) wearing Wonder Woman's boots. The promo included an appearance by Lynda Carter, star of the 1970s Wonder Woman, who plays the American president on Supergirl.
Wonder Woman (vol. 1) #105 revealed that Diana was formed from clay by the Queen of the Amazons, given life and power by four of the Greek and Roman gods (otherwise known as the Olympian deities) as gifts, corresponding to her renowned epithet: "Beautiful as Aphrodite, wise as Athena, swifter than Hermes, and stronger than Hercules", making her the strongest of the Amazons. Wonder Woman's Amazon training gave her limited telepathy, profound scientific knowledge, and the ability to speak every language – even caveman and Martian languages.
Gaines decided he needed another expert. He turned to Lauretta Bender, an associate professor of psychiatry at New York University’s medical school and a senior psychiatrist at Bellevue Hospital, where she was director of the children’s ward, an expert on aggression. She’d long been interested in comics but her interest had grown in 1940, after her husband, Paul Schilder, was killed by a car while walking home from visiting Bender and their 8-day-old daughter in the hospital. Bender, left with three children under the age of 3, soon became painfully interested in studying how children cope with trauma. In 1940, she conducted a study with Reginald Lourie, a medical resident under her supervision, investigating the effect of comics on four children brought to Bellevue Hospital for behavioral problems. Tessie, 12, had witnessed her father, a convicted murderer, kill himself. She insisted on calling herself Shiera, after a comic-book girl who is always rescued at the last minute by the Flash. Kenneth, 11, had been raped. He was frantic unless medicated or “wearing a Superman cape.” He felt safe in it—he could fly away if he wanted to—and “he felt that the cape protected him from an assault.” Bender and Lourie concluded the comic books were “the folklore of this age,” and worked, culturally, the same way fables and fairy tales did.
An American pilot and the love interest of Diana. On his role for the film, Pine said, "I am an American pilot who's a spy. It's like a boy's dream: You're either a spy or a fighter pilot. The first thing I wanted to be was a fighter pilot a long time ago. I wanted to be Goose [from Top Gun]". As to how his mortal character would interact with an Amazon, Pine stated, "When I first read the script, it had elements of Romancing the Stone, kind of a very classic fish out of water. Two people that don't really bond well at first and they're butting heads and just fun, witty banter". When speaking about meeting the director and being cast, Pine said, "Patty is a pretty incredible human being. When we first met about the part of Steve, she sat across from me and essentially acted out the entire film over the course of a two-hour lunch. She was so specific, so articulate, and so ardent. I would've said yes just for Patty alone." Pine went through a workout regimen for the film, commenting, "I got in incredible shape for this film" but also joking "I was also wearing about 75 pounds of clothing. What I realized is that I made a major mistake, I got in great shape and they just put clothes over all my hard work."
