Originally signed for three feature films, with Wonder Woman and Justice League being her second and third films, Gadot signed an extension to her contract for additional films. Jenkins initially signed for only one film, but in an interview with Variety, Geoff Johns revealed that he and Jenkins were writing the treatment for a Wonder Woman sequel and that he has a "cool idea for the second one". At the 2017 San Diego Comic Con, Warner Bros. officially announced a sequel would be released on December 13, 2019, and would be titled Wonder Woman 2; the date was later moved up to November 1, 2019, to avoid competition with Star Wars: The Rise of Skywalker. Later, Jenkins was officially signed to return as director, with confirmation that Gadot will be returning as the titular role. Days later, the studio hired Dave Callaham to co-write the film's script with Jenkins and Johns. On March 9, 2018, Kristen Wiig was confirmed to play Cheetah, the villain of the film. Later that month, it was announced that Pedro Pascal would have a key role in the film. In May 2018, long-time DCEU producer Zack Snyder confirmed on social media platform Vero that he, along with wife Deborah Snyder, will serve as producers on the Wonder Woman sequel. In June 2018, the title of the film was announced to be Wonder Woman 1984. A third film was announced in January 2019 to be taking place in the present.
After defeating Giganta in battle, Wonder Woman was approached by a lawyer who informed her that she had inherited the estate of Hercules, who had been killed. Shortly thereafter, she was told by A.R.G.U.S. that Hercules' body came from an area containing traces of energy unique to Apokolips. Diana visited Hercules' home and found a letter addressed to her, informing her of the location of her twin brother, Jason. She found him in Greece, and the two seemingly began to bond, only for Jason to turn against Diana after the arrival of Grail, who he had secretly allied himself with. Grail had begun killing children of the earthly gods in order to use their divine power to restore her father Darkseid to adulthood, as he had been turned into a baby at the end of the Darkseid War. Jason allied himself with her in order to exact revenge on Wonder Woman, as he resented her for not seeking him out after she learned of his existence some time ago and was envious of her. However, as Darkseid was about to drain Diana's life force, Jason regretted his actions and joined Wonder Woman in battle against Grail and Darkseid. Then, Hercules' lawyer revealed his true identity as the King of the Gods himself, Zeus. Zeus fought Darkseid while Wonder Woman took on his daughter, Grail. Ultimately, Zeus was defeated and his life force was drained by Darkseid, restoring the Apokoliptian to his full adult form. The Justice League arrived, forcing Darkseid and Grail to retreat through a Boom Tube. In the aftermath of the battle, Diana forgave her brother for his deceit.
In London, they deliver Maru's notebook to the Supreme War Council, where Sir Patrick Morgan is trying to negotiate an armistice with Germany. Diana translates Maru's notes and reveals that the Germans plan to release the deadly gas at the Western Front. Although forbidden by his commander to act, Steve, with secret funding from Morgan, recruits spy Sameer, marksman Charlie, and smuggler Chief Napi to help prevent the gas from being released. The team reaches the front in Belgium. Diana goes alone through No Man's Land and captures the enemy trench, allowing the Allied forces to help her liberate the village of Veld. The team briefly celebrates, taking a photograph in the village, while Diana and Steve begin to develop their own romance.
The storyline "The Circle" was focused on the revelation of a failed assassination attempt on Diana when she was a baby, by four rogue Amazons. These Amazons – Myrto, Charis, Philomela and Alkyone, collectively referred to as The Circle – were Hippolyta's personal guards and were extremely loyal and devoted to her. However, when Hippolyta decided to raise a daughter, The Circle was horrified and considered the baby ill-fate, one who would ruin their entire race. Thus, after Diana was sculpted out of clay and brought to life, The Circle decided to assassinate the baby. Their attempt was foiled however, and the four Amazons were imprisoned. After years, the Circle escaped their prisons with the help of Captain Nazi, and decided to accomplish their previously failed mission and kill Diana. Diana defeated Myrto, Charis, Philomela and then approached Alkyone, who runs off and succumbs to her death by falling into the ocean. The other three Amazons return to their prisons.
To defend himself against critics, Gaines, in 1940, hired Marston as a consultant. “‘Doc’ Marston has long been an advocate of the right type of comic magazines,” he explained. Marston held three degrees from Harvard, including a PhD in psychology. He led what he called “an experimental life.” He’d been a lawyer, a scientist and a professor. He is generally credited with inventing the lie detector test: He was obsessed with uncovering other people’s secrets. He’d been a consulting psychologist for Universal Pictures. He’d written screenplays, a novel and dozens of magazine articles. Gaines had read about Marston in an article in Family Circle magazine. In the summer of 1940, Olive Richard, a staff writer for the magazine, visited Marston at his house in Rye, New York, to ask him for his expert opinion about comics.
When Marston died in 1947 Robert Kanigher took over and Diana became less of a feminist character but during this time, her abilities expanded as she wore earrings that provided her with the air she needed when she was in outer space and she had an invisible plane. Extra additions included a tiara which could cut through almost anything and acted as a boomerang and her bracelets now had two way radios.
Wonder Woman’s appearance in the early golden age of comics made her the first prominent female superheroine. The psychologist William Moulton Marston created Wonder Woman somewhat as a counter reaction to the presence of prominent male superheroes (at this time Superman, Batman and Captain America), as well as a counterbalance to the "blood curdling masculinity" that was dominant at the time, with the hopes that the character could serve as an inspiration for young children (though in certain ways it was geared more towards female readers.) Marston had been partially motivated to create this character because of the accomplishments of his own wife, who was also an accomplished academic at a time when it was difficult for women to fulfill this role. As a result, the first Wonder Woman series contained many complementary articles and features which sought to highlight the inner power of women. There were articles for instance on the different career paths that women could pursue (according to the standards of the 1940s) as well as a series of stories on famous and accomplished women, called the Wonder Women of History. Marston introduced the character in All-Star Comics #8 in 1941. She became the lead character in Sensation Comics in 1941, and got her first solo book in 1942.
Hermes attacked Wonder Woman there, refusing to simply give up the child, but during their battle, War ripped the baby from Demeter's womb and disappeared. Unable to let a grave wound such as that go unattended, Diana saw to Demeter first, and the goddess warned that War could not be trusted. Worriedly, Diana and Orion returned to Manhattan to find that War had returned the baby to Zola. At last, the baby and his mother were reunited - and Orion would not have to look any further for the child he needed to kill.
The Diana Prince alias also played an important role after the events of Infinite Crisis. Wonder Woman was broadcast worldwide killing a villain named Maxwell Lord, as he was mind controlling Superman into killing Batman. When Wonder Woman caught him in her lasso, demanding to know how to stop Superman, Maxwell revealed that the only way to stop him was to kill Lord, so as a last resort Diana snapped his neck. To recover from the trauma of killing another person, the Amazon went into a self-imposed exile for one year. On her return to public life, Diana realized that her life as a full-time celebrity superhero and ambassador had kept her removed from humanity. Because of this she assumed the persona of Diana Prince and became an agent at the Department of Metahuman Affairs. During a later battle with the witch Circe, a spell was placed on Diana leaving her powerless when not in the guise of Wonder Woman.
