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.
Diana and Trevor arrived at the British War Council's meeting place. Trevor told her to stay behind while he retrieved one of his superiors from the war room. Curious, she followed him into the room, where dozens of men argued with each other while Sir Patrick Morgan struggled to be heard. The room fell silent as the men noticed Diana, as women were not allowed in the room; Trevor quickly escorted her out.
The British War Council quickly gathered to discuss the notebook. Their codebreakers were unable to decipher the two different languages that it was written in, but Diana quickly identified them as Ottoman and Sumerian. She read the book out loud, informing the council that Doctor Poison had created a new form of mustard gas based on hydrogen instead of sulfur, which gas masks would be useless against.
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."
Development for a live action Wonder Woman feature film began in 1996, with Ivan Reitman attached as producer and possible director. In 1999 the project became attached to Jon Cohen, who adapted Wonder Woman for producer Joel Silver, with the hope that Sandra Bullock would star. By 2001, Todd Alcott was hired to write the screenplay, with Silver Pictures backing the project. At that time, performers such as Mariah Carey and Catherine Zeta-Jones were also rumored to be possible candidates for the role of Wonder Woman. Leonard Goldberg focused on Bullock who said that she was approached for the role. Lucy Lawless, the star of Xena: Warrior Princess, was also under consideration, though she stated that she would have been more interested if Wonder Woman was portrayed as a "flawed hero". The screenplay went through various drafts written by Alcott, Cohen, Becky Johnston, and Philip Levens, and by August 2003, Levens had been replaced by screenwriter Laeta Kalogridis.
Trudging on, Hades expects their presence and tries sending spirits in order to stall and attack Diana and Hermes. Successfully defeating them, they wonder through a forest and find a cabin resembling Zola's farm house. Zola pops out and happily hugs Wonder Woman. Hades at that moment makes his grand entrance and frees them. Though, just before they escape, Hades beckons Wonder Woman to look behind, and shoots her with Eros pistols. She urges Hermes and Zola to leave while she is left at the mercy of Hades who wants her to be his bride. Here, she is preparing to wed Hades when she gives Diana her lasso, saying that if he truly loves him, she will confess it due to the properties of the lasso. She says yes, but will not go on with the wedding as it is more or less forced and not real love. She escapes his clutches and shoots him as a means of payback for shooting her.
She also had an array of mental and psychic abilities, as corresponding to Marston's interest in parapsychology and metaphysics. Such an array included ESP, astral projection, telepathy (with or without the Mental Radio), mental control over the electricity in her body, the Amazonian ability to turn brain energy into muscle power, etc. Wonder Woman first became immune to electric shocks after having her spirit stripped from her atoms by Dr. Psycho's Electro Atomizer; it was also discovered that she was unable to send a mental radio message without her body.
Coming to America for the first time, Wonder Woman comes upon a wailing army nurse. Inquiring about her state, she finds that the nurse wanted to leave for South America with her fiancé but was unable due to shortage of money. As both of them looked identical and Wonder Woman needed a job and a valid identity to look after Steve (who was admitted in the same army hospital), she gives her the money she had earned earlier to help her go to her fiancé in exchange for her credentials. The nurse reveals her name as Diana Prince, and thus, Wonder Woman's secret identity was created, and she began working as a nurse in the army.
