During Marston's run, Diana Prince was the name of an army nurse whom Wonder Woman met. The nurse wanted to meet with her fiancé, who was transferred to South America, but was unable to arrange for money to do so. As Wonder Woman needed a secret identity to look after Steve (who was admitted to the same army hospital in which Diana Prince worked), and because both of them looked alike, Wonder Woman gave the nurse money to go to her fiancé in exchange for the nurse's credentials and took Diana Prince as her alias. She started to work as an army nurse and later as an Air Force secretary.
William Marston's earliest works were notorious for containing subversive "bondage and sapphic-undertones" subtext. Among Wonder Women's infamous catchphrases, "Suffering Sappho", was a direct reference to lesbianism. Fredric Wertham's Seduction of the Innocent referred to her as the "lesbian counterpart to Batman" (whom he also identified as a homosexual). After Marston's death in 1947, DC Comics downplayed her sexuality and feminist origin. Wonder Women, without Marston's creative direction, become more "traditional" superhero fair; the lesbian relationships and sexual imagery disappeared from the "Wonder Woman" comic, along with Wonder Woman's super powers. During the Comics Code Authority-decades since, Wonder Woman's subversiveness had been gradually stripped away; subsequent comic book writers and artists either didn't know know what do with her or barely hinted at Wonder Woman's erotic legacy. Similar to whitewashing, Wonder Woman's queerness and feminist identity throughout the latter half of the 20th century was never discussed and rendered "invisible" in adaptations in favor of the dominant sexism portrayal of women in comic books.
Diana lifts a tank ready to crush Doctor Poison with it, but hesitates when she thinks about the love and compassion that Steve brought to her life when she realizes that he professed his love for her before leaving to sacrifice himself. Dropping the tank, Diana spares Doctor Poison, telling Ares that he is wrong about humanity. She tells him that while humans are everything Ares says and can be capable of the worst crimes, she's learned that they are equally capable of so much more: unbridled love and compassion. Ares engages Diana in a final fight, but is defeated after she fully embraces her powers as the God Killer and blasts Ares with powerful divine lightning. The soldiers, free from Ares' corruption, stop their fighting, thereby finally ending the war.
Flash and Wonder Woman get attacked by Steppenwolf and the Parademons before Batman helps her by killing one of the Parademons. Cyborg then falls into the Knightcrawler and hacks it in his control, which he uses it against Steppenwolf. But the Knightcrawler fails when Steppenwolf catched a missile and threw it against the wall, which then causes the harbor to flood which allows Steppenwolf to escape.
Flash and Cyborg save all the hostage, which Silas Stone tells Victor that Steppenwolf can not get the final Mother Box. Batman then jumps down into the Knightcrawler and saves Wonder Woman after a Parademon manages to briefly knock her out. The Knightcrawler gets attacked by Steppenwolf, and Barry helps Wonder Woman get her sword so she can help Batman.
Expert Social Intuit: Wonder Woman, as Diana Prince, has a high degree of social confidence (having had a century of experience living in "Man's World" after World War I), allowing her to intuitively determine how to interact with others, gain their respect and get her point across with calmness, eloquence, and charisma. Hence, Diana swiftly befriended the Wonder Men, she diplomatically greeted Bruce Wayne, matter-of-factly showing him that she can intellectually keep up with him (calmly responding to Bruce's anger at having been stolen from by her), she tactfully accepted a wine glass from the Gotham City Museum of Antiquities curator (despite seemingly disliking alcoholic beverages), she tactfully avoided correcting the curator on his claim that the fake replica of Alexander the Great's sword was the actual relic, and only when Lex Luthor insulted her father Zeus' memory did Diana have a look of visible dismay on her face (but even then she avoided making a scene), and only when Batman insulted her beloved Steve Trevor's memory did she finally lose her temper and shove Batman back. As a result, Diana remains extremely well-respected at the Louvre Museum, by fellow antique museum curators, by the Justice League, and even the extremely experienced Batman is almost instantly intrigued by her.
Lasso of Hestia: Wonder Woman's completely indestructible weapon, with the ability to force anyone it captures to obey the lasso's wielder and tell the truth. She successfully wielded it against Steve Trevor (in order to get the experienced spy to tell her the truth), General Ludendorff (in order to prevent his escape and kill him), Ares (in order to keep up with the violent God of War in battle), Doomsday (in order to temporarily restrain him, while Batman weakened him, and Superman delivered the finishing blow), and the resurrected Superman (in order to restrain him until the post-mortem amnesia wore off).
Gloria Steinem, editor for Ms. magazine and a major supporter of Wonder Woman, stated "... [Marston] had invented Wonder Woman as a heroine for little girls, and also as a conscious alternative to the violence of comic books for boys." Badower described a near-international incident (involving an unnamed Russian general rolling dozens of tanks and munitions through a shady mountain pass) as an outstanding example for standing up to bullies. "She ends up deflecting a bullet back and disarming the general," he says, adding that "she doesn't actually do anything violent in the story. I just think that Wonder Woman is smarter than that."
