Centuries ago, an argument between Aphrodite and Ares led to the creation of the Amazons, who have been guided and protected by the goddesses ever since. Ares' recent schemes to destroy the Amazons and his fellow gods led to an Amazon champion being chosen. This champion was the Princess Diana, daughter of Queen Hippolyta, whom Hermes escorted to Man's World. There she was called Wonder Woman. Hephaestus forged Wonder Woman's golden Lasso of Truth from the girdle of the earth-goddess Gaea, and her silver bracelets which he formed from the splintered Aegis of Zeus. While the Olympian gods were her patrons, other gods were her foes. Ares and his progeny, Deimos and Phobos, quickly set about challenging the princess in her quest. Phobos created the creature Decay from the "heart of the Gorgon," which Diana quickly dispatched. Meanwhile, Deimos recruited humans on opposing sides, inciting them to war.
The team learns that a gala will be held at the nearby German High Command. Steve and Diana separately infiltrate the party, with Steve intending to locate the gas and destroy it, and Diana hoping to kill Ludendorff, believing that he is Ares and thus killing him will end the war. Steve stops her to avoid jeopardizing his mission, but this allows Ludendorff to unleash the gas on Veld, killing its inhabitants. Blaming Steve for intervening, Diana pursues Ludendorff to a base where the gas is being loaded into a bomber aircraft bound for London. Diana fights and kills him, but is confused and disillusioned when his death does not stop the war.
Jenkins disagrees with this line of critique. She has stated that she was raised by a second-wave "feminist mother", who taught her to be "both super aware that there had been sexism but also: 'Congratulations—thank you, now I get to do whatever I want, Mom!'" Jenkins thus notes that it is this upbringing which has led her to question a feminist critique of Wonder Woman's costume. When she was working on her own version of Wonder Woman's "Gladiator" re-design of the outfit (in the 2016 film Batman v Superman: Dawn of Justice) Jenkins decided that Wonder Woman (as well as the other Amazons) "shouldn't be dressed in armor like men ... It should be different ... I, as a woman, want Wonder Woman to be hot as hell, fight badass, and look great at the same time—the same way men want Superman to have huge pecs and an impractically big body." Jenkins also notes that she is "frustrated" by the critique of Wonder Woman's appearance, stating "when people get super critical about her outfit, who's the one getting crazy about what a woman wears? That's who she is; that's Wonder Woman." Gal Gadot concurred with Jenkins, arguing that the character "is a feminist" as "feminism is about equality and choice and freedom. And the writers, Patty and myself all figured that the best way to show that is to show Diana as having no awareness of social roles. She has no gender boundaries. To her, everyone is equal."
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.
Impressed by this unknown woman's self-sacrifice, the Amazons entombed her with honors and clothed her in armor displaying the American flag pattern on her uniform, which they assumed were her heraldic colors. Trevor's legacy was also the primary reason why Ares arranged for Steve Trevor to bomb the island, as he could not resist the irony of the heroine's son unwittingly killing her admirers.
