The final remaining relics Darkseid needed were being guarded by A.R.G.U.S. at their HQ, so Darkseid decided to use a Boom Tube to transport the building and all its contents to his base in the Amazon Rainforest. The Female Furies retrieved the relics and put them into place while Wonder Woman fought Darkseid. With the relics' power, Darkseid was able to open a portal to Themyscira. As it is impossible for one who has set foot on Themyscira to return after leaving, Diana was unable to follow Grail through the portal. Grail invaded and began transforming the Amazons into creatures resembling Darkseid's Parademons. As Jason had never actually set foot on Themyscira, he followed Grail and met his mother Hippolyta for the first time since his birth. While Jason and Hippolyta fought off the transformed Amazons, Wonder Woman was able to defeat Darkseid through her love for her deceased father, Zeus, and her half-siblings, calling their spirits out of Darkseid's body and destroying him from the inside. The Amazons captured Grail and imprisoned her in the prison beneath Themyscira, alongside Ares, while Darkseid re-emerged somewhere on Earth. Jason was gifted a magical spear from his mother and returned to Earth.
Wonder Woman's advocacy for women rights and gay rights was taken a step further in September 2016, when comic book writer Greg Rucka announced that she is canonically bisexual, according to her rebooted Rebirth origin. Rucka stated, "... nobody at DC Comics has ever said, [Wonder Woman] gotta be straight. Nobody. Ever. They've never blinked at this." Rucka stated that in his opinion, she "has to be" queer and has "obviously" had same-sex relationships on an island surrounded by beautiful women. This follows the way Wonder Woman was written in the alternate continuity or non-canon Earth One by Grant Morrison, and fellow Wonder Woman writer Gail Simone staunchly supported Rucka's statement. Surprised at the amount of backlash from her fanbase, Rucka responded to "haters" that consensual sex with women is just as important to Wonder Woman as the Truth is to Superman.
Nick Pumphrey stated that Wonder Woman stands as a non-violent beacon of hope and inspiration for women and men. Grant Morrison stated "I sat down and I thought, 'I don't want to do this warrior woman thing.' I can understand why they're doing it, I get all that, but that's not what [Wonder Woman creator] William Marston wanted, that's not what he wanted at all! His original concept for Wonder Woman was an answer to comics that he thought were filled with images of blood-curdling masculinity, and you see the latest shots of Gal Gadot in the costume, and it's all sword and shield and her snarling at the camera. Marston's Diana was a doctor, a healer, a scientist."
Cheetah sought revenge upon Veronica Cale for abandoning her, and attempted to murder her, but was stopped by Wonder Woman. Cale refused to transform Cheetah back to her human form, and Cheetah herself decided that she no longer desired to be human. Having left her Lasso of Truth binding Phobos and Deimos, Diana was given it back by the Olympian Gods and reunited with Steve.
To find the perfect location to shoot the Amazon island of Themyscira, the birthplace of Wonder Woman herself, the film's producers searched all over the world, finally settling on the Cilentan Coast: a stretch of coastline on the Tyrrhenian Sea, located in the Province of Salerno in Southern Italy. It was chosen because most beaches in the world that sit below big cliffs disappear beneath the tide for part of every day. Production designer Aline Bonetto and her location manager Charles Somers considered 47 countries and visited several of them before they found what they were looking for. Bonetto explained that, "Italy had beautiful weather, a beautiful blue-green sea, not too much tide, not too much wave. Our effects team added some cliffs in post-production, and it was the perfect way to go". The estuary at Lower Halstow in Kent is featured in the scene in which Diana arrives at a Belgian creek to make her way to the warfront. Bill Westenhofer served as the visual effects supervisor for the film and Martin Walsh served as editor.
As Wonder Woman returned to her apartment, Hermes brought her to Olympus, where the gods declared her the new Goddess of War. Diana asked Apollo to restore Hera's godhood, but Apollo refused. Diana returned to London, and Apollo told her that she would not be able to ignore her responsibilities as Goddess of War for long. Diana was still angry at Hermes for his betrayal and asked him to leave, with Hermes stating that, just like she forgave Hera, perhaps in the future, she would forgive him.
One of the events that led to Infinite Crisis was of Wonder Woman killing the villain Maxwell Lord in Wonder Woman (vol. 2) #219. Maxwell Lord was mind-controlling Superman, who as a result was near to killing Batman. Wonder Woman tried to stop Superman, Lord (who was unable to mind control her) made Superman see her as his enemy Doomsday trying to kill Lois Lane. Superman then attacked Wonder Woman, and a vicious battle ensued. Buying herself time by slicing Superman's throat with her tiara, Wonder Woman caught Lord in her Lasso of Truth and demanded to know how to stop his control over Superman. As the lasso forced the wearer to speak only the truth, Lord told her that the only way to stop him was to kill him. Left with no choice, Wonder Woman snapped Lord's neck and ended his control over Superman. Unknown to her, the entire scene was broadcast live around every channel in the world by Brother Eye. The viewers were not aware of the entire situation, and saw only Wonder Woman murdering a Justice League associate. Wonder Woman's actions put her at odds with Batman and Superman, as they saw Wonder Woman as a cold-blooded killer, despite the fact that she saved their lives.
