As one of the longest continually published comic book characters, Wonder Woman’s history has undergone some changes over the years, though a few elements remain consistent in all of her depictions. She is the princess of the Amazons, a race of women who live free of men on Paradise Island (later dubbed Themyscira). After growing up on this island, Wonder Woman (whom her mother named Diana) journeys to Man’s World on a mission of diplomacy, peace, and love.
Ares told Diana that he had been imprisoned by the other Gods of Olympus and bound in chains that were secured by Aphrodite through the power of her love. He also told her that years ago, Phobos and Deimos had implanted false memories of Themyscira into her mind, and these had caused her to imagine aspects of her past that had never happened in reality. Meanwhile, Phobos and Deimos entered Themyscira and battled with the Amazons. Diana knew what she had to do, and called Ares to unite her with Phobos and Deimos. He teleported them to her, and using her Lasso of Truth, Wonder Woman bound them through the power of her unconditional love for them, as Aphrodite had done to Ares. With the twin gods defeated, Diana attempted to leave Ares' prison along with Veronica and Izzy, however Izzy's essence had been attached to the realm and could not return to Earth. Izzy was forced to either live out the rest of her days in the prison or live in Themyscira as an Amazon for eternity. She chose the latter and Veronica said goodbye to her daughter. Diana was briefly reunited with her mother, for the first time since she left the island.
The First Born imprisoned Wonder Woman in what remained of Olympus and ordered his forces to attack Themyscira. As they watched the confrontation, the First Born offered her a place in his goals of conquest, but she steadfastly refused, causing him to thrust a spike into her side. As Diana lied mortally wounded, Eris dragged her to Themyscira, for she wanted Diana to see her home destroyed and humiliate her. Recovering her strength, Wonder Woman punched Eris down and took Zola and Zeke to Olympus. Her plan was to place Zeke on the throne, so that he could be the new king of Olympus and end the bloodshed, but before she could, Poseidon revealed his presence.
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.
Superman begged his fellow heroes to arrest him, and while he was taken to the A.R.G.U.S. facilities, Diana expressed disapproval at Steve’s secret Justice League. Wonder Woman travelled to the Temple of Hephaestus and demanded Hephaestus tell her about what the box really was. Hephaestus answered that the box was not created by the Gods of Olympus and the truth was a mystery even to them. Wonder Woman decided to seek help from the Justice League Dark. Suddenly, the three Justice Leagues converged at the House of Mystery, where the heroes were divided, one side led by Wonder Woman, the other by Batman. Zatanna, having taken Wonder Woman’s side, teleported the group away. Wonder Woman’s group tracked Pandora’s box to Lex Luthor’s prison cell, where Pandora was offering the box to Luthor. Wonder Woman grabbed the box but was overwhelmed by its power.
Her outfit did not receive any prominent change until after the 2005–2006 Infinite Crisis storyline. Similar to her chestplate, her glowing belt was also shaped into a "W". This outfit continued until issue #600 – J. Michael Straczynski's run of Wonder Woman's altered timeline changed her outfit drastically. Her outfit was redesigned by Jim Lee and included a redesigned emblem, a golden and red top, black pants, and a later discontinued blue-black jacket.
Impressed by this unknown woman's self-sacrifice, the Amazons entombed her with honors and clothed her in armor displaying the American flag pattern on her uniform, which they assumed were her heraldic colors. Trevor's legacy was also the primary reason why Ares arranged for Steve Trevor to bomb the island, as he could not resist the irony of the heroine's son unwittingly killing her admirers.
