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".
Wonder Woman also met the Lamia of myth, who laid with Zeus and bore his children. Hera changed her into a snake-like creature and killed her children. She now lurks in the American sewers, acting as a benevolent caregiver to troubled children. She attempted to commit suicide using Diana's lasso (which she had her young friend Sneaker steal), but Diana stopped her and Lamia disappeared along with Sneaker, with whom she had developed a mother-daughter relationship.
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."
