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 the decision to relaunch the DC Universe into the new 52, this was done by the Flashpoint story arc, where the Reverse Flash has modified the past with a vastly different modern DC Universe having resulted. In this universe Diana leads a dystopian society of Amazons that have taken over England after a battle between the Amazons and the Atlanteans led by Aquaman.
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.
