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."
In present-day Paris, Diana receives a photographic plate from Wayne Enterprises of herself and four men taken during World War I, prompting her to recall her past. The daughter of Queen Hippolyta, Diana is raised on the hidden island of Themyscira, home to the Amazonian women warriors created by Zeus to protect mankind. Hippolyta explains the Amazonian history to Diana, including how Ares became jealous of humanity and orchestrated its destruction. When the other gods attempted to stop him, Ares killed all but Zeus, who used the last of his power to wound Ares and force his retreat. Before dying, Zeus left the Amazons the island and a weapon, the "Godkiller", to prepare them for Ares's return.
In February 1941, Marston submitted a draft of his first script, explaining the “under-meaning” of Wonder Woman’s Amazonian origins in ancient Greece, where men had kept women in chains, until they broke free and escaped. “The NEW WOMEN thus freed and strengthened by supporting themselves (on Paradise Island) developed enormous physical and mental power.” His comic, he said, was meant to chronicle “a great movement now under way—the growth in the power of women.”
Despite their displeasure at Diana's capture, Hephaestus was able to bring Lennox and Eros to Hades with him as guests to the wedding, without the aid of Hermes' staff. As the wedding drew nearer, Hades grew annoyed that few of his relatives had agreed to come. Diana's friends were the only attendees, aside from Strife, who merely wanted to cause her namesake emotion. Before the wedding ceremony took place, Hades insisted that Diana should prove her love by wearing his ring. The ring was a noose fashioned with the Lasso of Truth, and if Diana did not truly love him, he would kill her.
In 1954, Dr. Fredric Wertham alleged that there were lesbian subtexts to Wonder Woman and claimed comics contributed to juvenile delinquency in his book Seduction of the Innocent where despite a very obvious heterosexual relationship with Steve Trevor, Wertham asserted that Wonder Woman’s association with the Holliday Girls could be interpreted as a lesbian relationship. The Comics Code Authority was then introduced in reaction to Wertham 's claims against the entire industry.
