Their first adventure together as a serious couple involved a battle with Doomsday, a monster of Kryptonian legend. Superman, already familiar to the monster, explained that Doomsday was sealed into a pocket dimension called the Phantom Zone. Seeking preparation against enemies that could match them in power, Wonder Woman asked Hephaestus to forge weapons for them. Later, the Justice League intercepted the arrival of General Zod, another Kryptonian survivor. Superman gave him shelter in the Fortress of Solitude, but the couple discovered their relationship was now public knowledge.
Zeus has made a woman called Zola pregnant. Hera, due to this, is furious. She sets out to kill Zola, but Hermes finds her first, only to find out that Zola does not want to come with Hermes. Zola opens the door, and an arrow is shot at her direction; Hermes pushes her away in time, and gives her a key, as assassins sent by Hera and it teleports to Wonder Woman’s apartment, because Hermes enlisted Wonder Woman to protect Zola. Zola gives Wonder Woman the key, and it teleports both Wonder Woman and Zola back to Zola’s house. After Zola finds out that she is pregnant with Zeus, it gets revealed that one of Zeus’ children is going to take his place, by Zeus’ own will. Wonder Woman takes Zola, along with Hermes, to Themiscyra where Diana explains to her Mother, Queen Hippolyta, why she took with herself Zola and Hermes to Themiscyra. Alongside all of this, Hippolyta tells Diana about her true origins; that her real father is Zeus. Diana’s reaction to this isn’t very well, so she decides to abandon Themiscyra. Hera is aware of the fact that Wonder Woman is Zeus’ daughter, and she arrives to Themiscyra, furiously. Wonder Woman realized she did a mistake by leaving her home, so she went back to Themiscyra where she sees that everyone has been turned into snakes by Hera, except for Hippolyta, she was turned into stone. Apollo arrives in a bar searching for War (Ares), and explains to him that Zeus doesn’t even exist from what he’s sources says. Apollo takes this as his chance to become the king of Olympus and the Gods.
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 May 2017, early tracking had Wonder Woman opening with $65–75 million, and possibly as high as $105 million. The film opened Friday, June 2, 2017, across 4,165 theaters and made $38.7 million on its opening day, including $3.7 million in IMAX. It was the biggest single-day gross for a woman-directed film, ahead of the $35.9 million opening Friday of Catherine Hardwicke's Twilight in 2008 and the biggest opening day for a woman-led comic book superhero film, ahead of Ghost in the Shell ($7 million). This included $11 million it made from Thursday previews, also the best start for a film directed by a woman, surpassing Fifty Shades of Grey's $8.6 million which was directed by Sam Taylor-Johnson, and the third-biggest of the year, behind Beauty and the Beast and Guardians of the Galaxy Vol. 2. Of that, $1.5 million came from IMAX screenings.
