A sharpshooter and ally of Steve Trevor. On his role, Bremner said, "I play a character who's enlisted by Wonder Woman to help save the world as part of a small, unlikely band". Describing his character, Bremner stated "He's a shellshocked soldier who's been discharged from the war and is brought back to help on a secret mission". On working with Jenkins, Bremner commented, "Patty Jenkins is a force of nature. She has fantastic vision, strength and enthusiasm, which is completely infectious and motivates a cast and crew of thousands to really go beyond themselves."
Wonder Woman actress Gal Gadot reacted positively to Diana's rebooted orientation, and agreed her sexuality was impacted by growing up in the women-only Themyscira. Gadot stated that Wonder Woman feels she need not be "labelled sexually", and is "just herself". "She's a woman who loves people for who they are. She can be bisexual. She loves people for their hearts." Coming from a society that was only populated by women, "'lesbian' in [the world's] eyes may have been 'straight' for them." "Her culture is completely free from the shackles of heteronormativity in the first place so she wouldn't even have any 'concept' of gender roles in sex."
Perhaps due to her Amazonian background, Diana greatly respects other noble selfless warriors, as evidenced when she attended Superman's funeral in Smallville and spoke of how he had been much more than a soldier (adding to what Batman said about Metropolis burying an empty casket). As a result of her great posthumous respect, she was, therefore, more than willing to aid Batman in honoring the heroic death of Superman, by helping round up the metahumans from Lex Luthor's files to form a team of superheroes (later known as the Justice League) to protect the world from the imminent mysterious alien invader Steppenwolf and his Parademon minions after Superman's death left the world vulnerable.
By the end of the war, Diana began to lose faith in both humanity and herself after Ares opened her eyes to humanity's potential for evil. While she still believed in the power of love and compassion to change humanity for the better, Diana was left sobered and emotionally broken over certain events from the war, such as the use of Dr. Poison's gas to massacre the entire village of Veld, and Steve Trevor's self-sacrificing death. After witnessing a "century of horrors", Diana largely stepped away from heroics until she witnessed the seemingly unstoppable Doomsday wreck havoc; ultimately joining in to battle him alongside Batman and Superman. After witnessing Superman's own sacrifice to stop the monster, however, Diana turned once again towards heroics; demonstrating not only her underlying belief in her own core values, but also in the positive effect true heroes can have on the world.
Diana, Trevor, Sameer, and Charlie sat at a table together as Trevor proposed his plan to them. Sameer and Charlie were willing to join them, if they were paid for the job. Trevor, however, had no money. The two refused the job. Sameer told Diana that all the payment he needed was a photograph of her; Diana countered that he wouldn't need one, as she was going with them. He and Charlie were baffled by her response.
With Zola's pregnancy reaching full term, she insisted on seeing her own doctor in Michigan. While there, they were all attacked by Artemis and Apollo. Unprepared, Diana and her companions were defeated, and Zola was taken to Mount Olympus to be delivered to Hera in exchange for the throne. Apparently, Hera was willing to give up her throne for the sake of revenge. However, she had expected Zeus to return as soon as his rule was threatened, which he did not. When Apollo sat on the throne, he was crowned ruler, and when he learned of Hera's deceit, he exiled her from Olympus.

Wonder Woman and the other heroes were finally released from the Firestorm Matrix when Batman used the Lasso of Truth on Firestorm. Superman was still infected with the Kryptonite shard inside his nervous system, but Lex Luthor was able to extract it, saving Superman's life. Luthor also assembled a group of villains that defeated the Crime Syndicate. Later, at the Batcave, Wonder Woman and the Justice League talked about the enemy that destroyed the Crime Syndicate's world and came to the conclusion that Darkseid would return.
