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.
Wonder Woman did not keep her identity a secret, and initially did not consider herself a superheroine. Indeed, her character was wide-eyed and naive, innocent and without guile. Diana spoke only Themyscirian, a variation of ancient Greek, and had to learn English when she arrived in the United States. Fortunately, Diana soon met Julia Kapatelis, a scholar in Greek culture, and her daughter Vanessa Kapatelis who helped the Amazon princess adjust to the world of men. However, for all her apparent naiveté, Diana was a trained warrior, and had no compunction against using deadly force when called for. For example, she felled the god Deimos in battle and felt completely justified under the circumstances. Through Pérez's tenure on the book, Diana confronted war, injustice, inequality, death and conflicts involving the Olympian Gods.
The story then centers on Apollo trying to take over as King of Olympus due to his father Zeus' absence and Wonder Woman's efforts to protect Zola from him, as it is prophesied that one of Zeus' children will be his downfall which Apollo considers to be Zola's child. Wonder Woman receives the power of flight by one of Hermes' feathers piercing her thigh and Zola's baby is stolen by Hermes at the end and given to Demeter. The issue's last page shows a dark and mysterious man rising from the snow, taking a helmet and disappearing. Issues 7–12 are collected in a hardcover titled Wonder Woman Vol. 2: Guts, scheduled for release in January 2013.
On November 3, 2016, Rupert Gregson-Williams was hired to write and compose the film's music. He was joined by Evan Jolly, Tom Howe, Paul Mounsey, and Andrew Kawczynski, who provided additional music. The soundtrack was released on CD, digital, and vinyl the same day as the film. Australian musician Sia sang a song for the film, titled "To Be Human", featuring English musician Labrinth. Written by Florence Welch and Rick Nowels, the track is also featured on the soundtrack. The soundtrack also features samples from Wonder Woman's theme "Is She with You" from the Batman v Superman: Dawn of Justice soundtrack composed by Hans Zimmer and Junkie XL.
On occasions Wonder Woman has employed a magical sword of unknown (though presumably Amazon) origin. This sword has been used most specifically against those with the power of invulnerability as invulnerability generally does not work against magical items. It is generally represented as a short sword. In Wonder Woman (vol. 4) #15, Hephaestus modifies Diana's bracelets so that she can manifest two short swords from them during battle.
This new era of the comic book was influenced by the British television series The Avengers, with Wonder Woman in the role of Emma Peel. With Diana Prince running a boutique, fighting crime, and acting in concert with private detective allies Tim Trench and Jonny Double, the character resembled the Golden Age Black Canary. Soon after the launch of the "new" Wonder Woman, the editors severed all connections to her old life, most notably by killing Steve Trevor.
In the New 52, the night when she turned 8, Ares appeared before Diana and offered to train her above and beyond the abilities of the Amazons, having seen her potential to eventually become his replacement as the God of War. Though the training was one for one night each month, the year was noticed with Diana improving tremendously compared to the other Amazons.
In one episode, a newspaper editor named Brown, desperate to discover Wonder Woman’s past, assigns a team of reporters to chase her down; she easily escapes them. Brown, gone half mad, is committed to a hospital. Wonder Woman disguises herself as a nurse and brings him a scroll. “This parchment seems to be the history of that girl you call ‘Wonder Woman’!” she tells him. “A strange, veiled woman left it with me.” Brown leaps out of bed and races back to the city desk, where he cries out, parchment in hand, “Stop the presses! I’ve got the history of Wonder Woman!” But Wonder Woman’s secret history isn’t written on parchment. Instead, it lies buried in boxes and cabinets and drawers, in thousands of documents, housed in libraries, archives and collections spread all over the United States, including the private papers of creator Marston—papers that, before I saw them, had never before been seen by anyone outside of Marston’s family.
