Voiced by Vanessa Marshall. This movie is based on the Flashpoint event which was meant to be the reboot of the DC Universe. After the Barry Allen travels back in time to save his mother, he changes the whole timestream making everything different. Her role in this movie is that she has a war against Aquaman because she killed Mera and it made Aquaman angry, Amazons against Atlanteans. The Amazons has made London ''New Themyscira''. She defeats Aquaman at the end of the movie, but the rest of the world gets destroyed by Captain Atom's energy, Captain Atom was held as a last resort by Aquaman, and Flash manages to revert everything as it was right before the world got consumed.
Wonder Woman is suggested as being queer or bisexual, as she and another Amazon, Io, had reciprocal feelings for each other. Grant Morrison's 2016 comic Wonder Woman: Earth One, which exists parallel to the current DC comics Rebirth canon, Diana is depicted being kissed on her right cheek by a blonde woman who has put her left arm around Diana.
Siracca tells Diana how she and her mother were killed by the hands of the jealous goddess Hera. Although she was torn to shreds by Hera's fury, Zeus took pity on her and turned her into wind. The very same wind that spills secrets to Lennox. Wonder Woman share her encounter with Hera and how she so desperately needs to find Zola's child, stolen due to Hermes. Siracca attempts to help Diana in finding Hermes and the baby. She suggests meeting Milan, once again, another child of Zeus for advice. Diana treks off to New York to find him.
“Noted Psychologist Revealed as Author of Best-Selling ‘Wonder Woman,’” read the astonishing headline. In the summer of 1942, a press release from the New York offices of All-American Comics turned up at newspapers, magazines and radio stations all over the United States. The identity of Wonder Woman’s creator had been “at first kept secret,” it said, but the time had come to make a shocking announcement: “the author of ‘Wonder Woman’ is Dr. William Moulton Marston, internationally famous psychologist.” The truth about Wonder Woman had come out at last.
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.
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.
Still puzzled as to Diana's identity, Bruce discovers more about her amongst the data he stole from Lex Luthor. He sees a photograph of her alongside the Wonder Men, taken in Belgium in 1918 during the closing days of World War I. He then makes contact with her via her laptop, sharing extra information that Luthor had on both her and other metahumans, such as the Flash, Aquaman, and Cyborg. Diana is visibly intrigued and shocked at this revelation, as Flash's lightning reminds her of that of Ares, Aquaman reminds her of depictions of Poseidon, while the Mother Box that created Cyborg reminds her of the one she briefly saw back on Themyscira. Diana resolves to take some time to think this revelation over, does not answer Bruce's e-mail, and instead proceeds with her plans to depart Metropolis on a flight back to France, through Turkey.
Coming to America for the first time, Wonder Woman comes upon a wailing army nurse. Inquiring about her state, she finds that the nurse wanted to leave for South America with her fiancé but was unable due to shortage of money. As both of them looked identical and Wonder Woman needed a job and a valid identity to look after Steve (who was admitted in the same army hospital), she gives her the money she had earned earlier to help her go to her fiancé in exchange for her credentials. The nurse reveals her name as Diana Prince, and thus, Wonder Woman's secret identity was created, and she began working as a nurse in the army.
