On October 21, 2016, the United Nations controversially named Wonder Woman a UN Honorary Ambassador for the Empowerment of Women and Girls in a ceremony attended by Under-Secretary-General for Communications and Public Information Cristina Gallach and by actors Lynda Carter and Gal Gadot. The character was dropped from the role two months later after a petition against the appointment stated Wonder Woman was "not culturally...sensitive" and it was "alarming that the United Nations would consider using a character with an overtly sexualized image".
In 2016, DC Comics once again relaunched all of its publications as part of the "DC Rebirth" continuity reboot, and the new fifth volume of Wonder Woman was released bi-monthly with writer Greg Rucka. This fifth volume of Wonder Woman is part of the "DC Universe", the current continuity established after Rebirth. Initially, the new series does not use a regular storyline that exists between each issue; instead two separate storylines share the book, with an installment of one story published every other issue, and those of the other storyline published in between those. This practice began with the storyline "The Lies" for the odd numbered issues, and "Year One" for the even numbered issues. The new storyline as presented in these issues effectively retcons the events from the previous New 52 series. "The Lies" storyline reveals that a number of events from the previous Wonder Woman series in which Diana was made the Queen of the Amazons and the God of War, was in fact all an illusion created by a mysterious villain, and she had never once been back to Themyscira ever since she left, nor is she capable of returning there. The "Year One" story is presented as an all-new origin story for Diana, which reveals how she received her powers from the Olympian Gods, which was intended to bring her back to her classical DC roots. Wonder Woman appears in DC Rebirth with a revised look, which includes a red cape and light armor fittings. Along with her lasso and bracelets, she now regularly utilizes her sword and shield. Wonder Woman: Rebirth artist Liam Sharp described the new armor as a utilitarian piece which allows her to move more freely. Starting from Issue 26, the series returned to a regular storyline between each issue.
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."
Wonder Woman engaged the First Born, but he quickly gained the advantage and attempted to kill Zeke. However, War challenged the First Born to a fight while Wonder Woman recovered. Then, Wonder Woman grabbed a spear and impaled both Ares and the First Born. As he died, Ares congratulated Wonder Woman for being a great warrior. Wonder Woman spared the First Born's life and went with Hades to take Ares' body to the River Styx.
