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.
At the time of her debut, Wonder Woman sported a red top with a golden eagle emblem, a white belt, blue star-spangled culottes, and red and golden go-go boots. She originally wore a skirt; however according to Elizabeth Martson, "It was too hard to draw and would have been over her head most of the time." This outfit was entirely based on the American flag, because Wonder Woman was purely an American icon as she debuted during World War II. Later in 1942, Wonder Woman's outfit received a slight change – the culottes were converted entirely into skin-tight shorts and she wore sandals. While earlier most of her back was exposed, during the imposition of the Comics Code Authority in the mid-1950s, Wonder Woman's outfit was rectified to make her back substantially covered, in order to comply with the Authority's rule of minimum exposure. During Mike Sekowsky's run in the late 1960s, Diana surrendered her powers and started using her own skills to fight crime. She wore a series of jumpsuits as her attire; the most popular of these was a white one.
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.
Steppenwolf then grabs Silas Stone, which Cyborg shots Steppenwolf and saves his father, and Wonder Woman helps out by attacking the Parademons and taking Steppenwolf to a different part of the factory. While Batman fights the Parademons, Barry goes and save one of the employees. Steppenwolf tells the Parademons that he will deal with Diana alone; meanwhile, Batman is being attacked by one of the Parademons as he tells Alfred that he needs the Knightcrawler, which he sent the machine to Bruce.
The American theme of Diana's costume was explained by Pérez in the Challenge of the Gods storyline in which Diana engaged in a series of trials arranged by Zeus as punishment for refusing his advances. Diana met the spirit of Steve Trevor's mother, Diana Trevor, who was clad in armor identical to her own. Trevor revealed that during World War II she had crashed on Themyscira while on duty as a U.S. Army pilot. She blundered into an Amazon battle against Cottus, a multi-armed demon, at the portal to the underworld. Trevor was drawn into the battle, although she was armed only with her side arm. She wounded the beast before suffering a mortal blow, allowing the Amazons to reseal the portal.
During the Silver Age, under writer Robert Kanigher, Wonder Woman's origin was revamped, along with other characters'.

Within the live-action DC Extended Universe films, Wonder Woman debuted in Batman v Superman: Dawn of Justice (2016) and was featured as the main character in Wonder Woman (2017).
