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.
An American pilot and the love interest of Diana. On his role for the film, Pine said, "I am an American pilot who's a spy. It's like a boy's dream: You're either a spy or a fighter pilot. The first thing I wanted to be was a fighter pilot a long time ago. I wanted to be Goose [from Top Gun]". As to how his mortal character would interact with an Amazon, Pine stated, "When I first read the script, it had elements of Romancing the Stone, kind of a very classic fish out of water. Two people that don't really bond well at first and they're butting heads and just fun, witty banter". When speaking about meeting the director and being cast, Pine said, "Patty is a pretty incredible human being. When we first met about the part of Steve, she sat across from me and essentially acted out the entire film over the course of a two-hour lunch. She was so specific, so articulate, and so ardent. I would've said yes just for Patty alone." Pine went through a workout regimen for the film, commenting, "I got in incredible shape for this film" but also joking "I was also wearing about 75 pounds of clothing. What I realized is that I made a major mistake, I got in great shape and they just put clothes over all my hard work."

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.
In the Silver Age, Wonder Woman's history received several changes. Her earlier origin, which had significant ties to World War II, was changed and her powers were shown to be the product of the gods' blessings, corresponding to her epithet, "beautiful as Aphrodite, wise as Athena, stronger than Hercules, and swifter than Hermes". The concepts of Wonder Girl and Wonder Tot were also introduced during this period.
The sister of Hippolyta, general of the Amazonian army, Diana's aunt and mentor. On being cast for the film, Wright said, "It's two-fold because when Patty Jenkins called me, the director, it was a three-minute long conversation. She said, 'I'm doing a movie about Wonder Woman. Do you want to be her trainer?' And I was like, 'Yes. Of course.' And the general of the Amazonian army. That was pretty cool." Describing her character mentoring and training Diana to be a warrior, Wright said, "It's a sixth sense that it is coming and I think that's also in the mythological story behind Antiope and Queen Hippolyta. They know it's coming and it's her duty as the aunt to her young niece to make sure she is the fiercest warrior of all time." On the Amazons fighting style, Wright said, "It's hand combat. Yes, swords and knives and arrows, but the precision that they have, right, as these warrior women; it's so nice to see that disparity between what we had in the day of just raw fighting materials and the guns and how easy that is in comparison." The message of the film, Wright stated, "is not just female empowerment. It's about love and justice. That's what the film's about. And what a great message to spread to our little ones." Commenting about training for the film, Wright said, "The most empowering was to get into that physical shape. So we were doing horseback riding training, weight training, martial arts, and 2,000 to 3,000 calories a day".
With Wonder Woman arriving in pursuit, Strife warned of the prophecy Apollo and Artemis feared: a child of Zeus would kill a god to take the throne. That child could be either Diana or Zola's child. Sending Zola back with Hermes to have her baby in peace, Diana warned that if they were not left alone, she would fulfil the prophecy herself. Unfortunately, upon her return to Michigan, Diana found that Hermes had betrayed them, and once Zola gave birth to her son, he whisked the child away, and gave it to Demeter. Diana swore to get the boy back and bring Hermes to justice.
