After Crisis on Infinite Earths, George Pérez rebooted the character in 1987. She wore an outfit similar to her 1970s one, but now with a larger glowing golden belt. This outfit continued until William Messner-Loebs' run, which had Diana pass on the role of Wonder Woman to Artemis. No longer Wonder Woman, Diana sported a new black biker-girl outfit designed by artist Mike Deodato Jr. After John Byrne took over writing and art duties, he redesigned the Wonder Woman outfit (Diana was reinstated as Wonder Woman at the end of Loebs' run) and joined the emblem and belt together.
In 2010, Warner Bros. stated that a Wonder Woman film was in development, along with films based on DC Comics superheroes the Flash and Aquaman. Both Wonder Woman and Aquaman were still under consideration for solo film subjects as of June 2013. DC Entertainment president Diane Nelson said Wonder Woman "has been, since I started, one of the top three priorities for DC and for Warner Bros. We are still trying right now, but she's tricky." On October 5, 2013, WB chairman and CEO Kevin Tsujihara said he wanted to get Wonder Woman in a film or on TV. Shortly afterward, Paul Feig said he had pitched the studio an idea for Wonder Woman as an action-comedy film. The studio then began to search for female directors to direct the film. While Michelle MacLaren was the studio's initial choice to direct (and while she initially indicated interest), she eventually left the project due to creative differences.
The success of the superhero television series Supergirl informed the marketing and promotion strategy used for Wonder Woman. According to Time Warner chief marketing officer Kristen O'Hara, they wanted to approach the Wonder Woman marketing campaign in a light manner, similar to how they did with Supergirl. O'Hara elaborated that the modest campaign route they took for Supergirl aided in establishing a large central fanbase among women well in advance of the series, which reportedly generated 5 million female superhero fans in one week. They were then able to model over time, and grow that audience leading up to the 15-months-later release of Wonder Woman. Though neither the film nor the series are aimed exclusively at women, the latter's campaign gave them their first opportunity to begin collecting data about female superhero fans. In May 2017, a promo for Wonder Woman was released during the season finale of Supergirl, featuring a remix of the song "These Boots Are Made for Walkin'" and Supergirl (Melissa Benoist) wearing Wonder Woman's boots. The promo included an appearance by Lynda Carter, star of the 1970s Wonder Woman, who plays the American president on Supergirl.
Meanwhile, the New God Orion had learned that a great danger was to be found on Earth in the form of the child of a god. He sought out his old friend Milan for help. Nearby, Diana and Lennox decided to seek Milan by themselves, leaving Zola and Hera to bicker with one another in the meantime. They found him in the old subway system with Orion. Though their encounter began violently, Lennox managed to explain that they had accounted for six of the seven children of Zeus. Orion believed that one of those seven was the child that he had been sent to kill. Lennox and Diana concluded that he was referring to Zola's kidnapped son, and so they convinced Milan to search through the ether until he located the boy in the arms of Demeter. When they all returned to Manhattan to find Zola and Hera in a bar with War, Diana managed to convince her uncle to lead her to Demeter's domain.
Diana sees Sir Patrick Morgan in the base, who reveals himself to be the true Ares, and tells her of his plan for a world without humanity by having them destroy each other. Ares proposes that Diana help him accomplish his vision of paradise, but Diana promptly refuses, not wanting to kill billions of innocents. Ares then reluctantly engages her in an epic battle while Steve and his comrades attempt to dismantle the plane harboring the mustard gas.
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.
Before she was Wonder Woman, she was Diana, princess of the Amazons, trained to be an unconquerable warrior. Raised on a sheltered island paradise, when an American pilot crashes on their shores and tells of a massive conflict raging in the outside world, Diana leaves her home, convinced she can stop the threat. Fighting alongside man in a war to end all wars, Diana will discover her full powers…and her true destiny.
Unfortunately, not long after Diana left, Hera came for her vengeance, and though she could not bring herself to kill Hippolyta, she could not forgive her either. Feeling regret at giving up the only real family she had, Wonder Woman returned to Themyscira to find the Amazons absent, and her mother turned to stone. Shortly after, Wonder Woman encountered Lennox, a man who claimed to be another of Zeus' bastard children. After learning that Zeus has gone missing, they confronted the Gods of Olympus, Poseidon and Hades, in order to prevent them from taking over Zeus’ throne. To prevent a war between gods, Diana proposed that the two brothers share Heaven with one ruling during the day, and the other at night. Hera angrily interceded, which was what Diana had planned, and using Hermes' staff she transported herself to Mount Olympus to face Hera alone. She warned that she would make Hera regret what she had done to her mother before returning to Earth. Unfortunately, by the time she had returned, Hades had kidnapped Zola with the warning that Diana would need to make good on her bargain or Zola and her child would die.
