The Amazon Queen of Themyscira and Diana's mother. After meeting the director for the role, Nielsen said, "Patty and I met in London, and we just hit it off from the get-go. We couldn't stop talking. What was supposed to be a one-hour meeting turned into a two-and-a-half-hour lunch and we just really got each other." She described Jenkins's directing style for the film as "She's also the kind of director that I really flourish under. She has very strong and particular and specific ideas about what it is she wants to say. She comes from a place of strength always. And so, when you are dealing with someone like that, you feel absolutely free to be vulnerable, to be creative, and I am a big researcher." On playing the character, Nielsen said, "It was a complete and utter pleasure and I absolutely loved every second of playing her." On her character being Diana's mother and Amazonian queen, Nielsen stated, "I'm queen and I'm preparing my child for a world that entails a lot of responsibility. So it was important to me to bring that into the character." She read The Amazons by Adrienne Mayor to familiarize herself with women warriors and said "I used what I learned in Mayor's book as a rallying cry for how I approached Hippolyta. And then, of course, what is a leader who is elected by her peers every year and has been doing this for a thousand years? That too was interesting to think about". Nielsen went through a workout regimen for the film, saying "I did six hours a day. You know, two hours of weight training, two hours of swords training, and then two hours of horseback riding".
The New 52 version of the character has been portrayed to be a younger, more headstrong, loving, fierce and willful person. Brian Azzarello stated in a video interview with DC Comics that they're building a very "confident", "impulsive" and "good-hearted" character in her. He referred to her trait of feeling compassion as both her strength and weakness.
After preventing a terrorist attack at a refugee camp in Greece, Wonder Woman returned to a government facility in the United States and was examined by a sickly doctor, Dr. Shannon Crawford. That evening, Diana attended the wedding of Etta Candy's brother, where she discovered a bomb seconds away from detonation hidden underneath one of the tables. She was able to contain the blast, but Etta was injured by a piece of shrapnel. She returned Etta to Dr. Crawford who removed the shrapnel, before touching Wonder Woman with an Amazon-strength sedative she had developed, leaving Diana too weak to fight back. Dr. Crawford told Diana that she had a rare genetic illness, and that she intended to use Diana's Amazon blood to develop a cure, saving her life as well as providing life-saving treatment for others afflicted with the same disease. Diana awoke to discover Crawford had developed Amazonian strength as a result of the blood transfusion. She was able to bind Dr. Crawford in the Lasso of Truth, which rejected the lie and restored Crawford to her previous state. Having lost hope for a cure, Crawford injected herself with the sedative, killing her. Wonder Woman was too late to stop her, but she understood Crawford's decision to end her pain and held her as she died.
“As to the ‘advanced femininity,’ what are the activities in comic books which women ‘indulge in on an equal footing with men’? They do not work. They are not homemakers. They do not bring up a family. Mother-love is entirely absent. Even when Wonder Woman adopts a girl there are Lesbian overtones,” he said. At the Senate hearings, Bender testified, too. If anything in American popular culture was bad for girls, she said, it wasn’t Wonder Woman; it was Walt Disney. “The mothers are always killed or sent to the insane asylums in Walt Disney movies,” she said. This argument fell on deaf ears.
