The screenplay will be co-written by three people: Jenkins, Johns, and The Expendables writer Dave Callaham. Callaham’s involvement was revealed on Sept. 13, disappointing fans who hoped for another woman on the film’s core creative team. That being said, it seems that Callaham was personally recruited by Jenkins herself since they already worked together on a previous project.
An immortal Amazon warrior goddess who is the crown princess of Themyscira and the daughter of Queen Hippolyta and Zeus given to the Amazons to raise, and half-sister of Ares. Describing Wonder Woman and her appeal, Gadot said, "She's relatable. She has the heart of a human and is very compassionate, but her experiences—or lack of them, her naivete, really—make her interested in everything around her and able to view the world in a way that we'd all like to: with a genuine curiosity." On Diana's relationship with her mother, Gadot said, "Diana is a very opinionated girl. Her mother is very opinionated. Her mother is very protective as well, and they have, you know, the very natural clash that a mother has with her daughter, with their daughters, the first time they want to leave home." On taking on the role as Wonder Woman, Gadot stated, "I feel very privileged that I got the opportunity to portray such an iconic, strong female character. I adore this character and everything that she stands for and everything that she symbolizes." On Diana going to the world, Gadot stated, "When Diana comes to the real world she's completely oblivious about gender and society rules, that women are not equal to men." Describing Diana's relationship with her mother and aunts, Jenkins said, "She is the only child they raised together. And their love for her manifests in a different way for each of them." On working with Gadot, Jenkins said, "Gal quickly became the person I wanted to talk to about everything. We'd shoot together all day. And then on weekends, we'd be like, 'What do you want to do?' That's maybe not totally normal."
Immortality: Wonder Woman, due to being an Amazon, has lived for millennia without visibly aging, with her being roughly 5000 years old (having been born right after the War of the Gods), and having been present in the "Man's World" since World War I. She is thus the oldest member of the Justice League by far (though still roughly a millenia younger than Enchantress, and even more so than Ares and Steppenwolf), making her an ageless immortal, much like Superman.
Years later, their deceit was discovered by Hippolyta. Angry at Antiope for defying her decision, Hippolyta sent Diana back to her room so that she could speak to her sister alone. Antiope reasoned with the Queen, reminding her that Ares was alive and would come for Diana some day. Hippolyta accepted this with some difficulty, and ordered Antiope to train Diana harder than any Amazon before her, until she was better than even Antiope herself, the Amazons' fiercest warrior. Thus, with the blessing of her mother, Diana formally began extensive training in all forms of Amazonian combat. Over the years, she became a formidable warrior.
While not completely invulnerable, she is highly resistant to great amounts of concussive force and extreme temperatures and matches Superman in this regard. She is completely immune to his heat vision, virtually any damage, or even the core of the sun. However, edged weapons or projectiles applied with sufficient force are able to pierce her skin. Due to her divine origins, Diana can resist many forms of magical manipulation.
Pérez and Potter wrote Wonder Woman as a feminist character, and Pérez's research into Greek mythology provided Wonder Woman's world with depth and verisimilitude missing from her previous incarnation. The incorporation of Greek gods and sharply characterized villains added a richness to Wonder Woman's Amazon heritage and set her apart from other DC heroes.
Shortly after, Diana decides to venture to the Underworld to look for Zola. Lennox requests to come, but Diana shoots down his attempt, saying that she is going solo, save for Hermes as the only way to go to Hades is to either die or be escorted by Hermes. While in the Underworld, Hermes tells that the place is more or less an extension of Hades' (now preferring to call himself "Hell") will.
Hermes attacked Wonder Woman there, refusing to simply give up the child, but during their battle, War ripped the baby from Demeter's womb and disappeared. Unable to let a grave wound such as that go unattended, Diana saw to Demeter first, and the goddess warned that War could not be trusted. Worriedly, Diana and Orion returned to Manhattan to find that War had returned the baby to Zola. At last, the baby and his mother were reunited - and Orion would not have to look any further for the child he needed to kill.
