This section of the history takes place during the New 52, between the events of Flashpoint and DC Rebirth. It was later revealed that much of Wonder Woman's history from this time was an elaborate illusion created by the Gods of Olympus to keep her away from Paradise Island. All or part of this section may have been part of that illusion and no longer valid in Rebirth.
Seeking answers, Wonder Woman sought out an old friend that she believed could provide the way to Themyscira: Barbara Minerva, the Cheetah. Cheetah agreed to help, under the condition that Diana kill the plant-god Urzkartaga and free Barbara from her curse, which Diana agreed to do. When she located Urzkartaga, however, she discovered Steve Trevor and some of his fellow soldiers had been captured by Colonel Andres Cadulo, who intended to become the embodiment of the god and sacrifice Steve in the process. Wonder Woman freed dozens of Cadulo's captives and, with the help of Cheetah and the women he had captured, succeeded in destroying Urzkartaga and freeing Barbara from the curse of the Cheetah. With Barbara's help, Diana and Steve were able to find "Themyscira", though Diana was surprised to find her mother alive and well despite remembering her as dead at the hands of Hera. After removing her bracelets Diana realized that her past interactions with these representations of the Amazons and her home were in fact an illusion, and that she may have never returned home since she originally left to escort Steve to the United States. Upon this realization, Diana suffered a mental breakdown.
On occasions Wonder Woman has employed a magical sword of unknown (though presumably Amazon) origin. This sword has been used most specifically against those with the power of invulnerability as invulnerability generally does not work against magical items. It is generally represented as a short sword. In Wonder Woman (vol. 4) #15, Hephaestus modifies Diana's bracelets so that she can manifest two short swords from them during battle.
A new pantheon of gods has been born! But who are they? Where did they come from? What do they want? All questions for Wonder Woman, because she played more of a role in their arrival than you’d think! Will it fall to Diana to end their existence as well? Meanwhile, Wonder Woman’s brother Jason learns his true purpose. It’s all here in this extra-sized anniversary issue!
Although she initially forbids Diana to be trained as a warrior, Hippolyta reluctantly agrees to let General Antiope, Hippolyta's sister and Diana's aunt, train her, only more rigorously than any other warrior. In 1918, Diana, now a young woman, rescues US pilot Captain Steve Trevor when his plane crashes off the Themysciran coast. The island is soon invaded by German soldiers that had been pursuing Trevor. The Amazons kill the crew, but Antiope sacrifices herself to save Diana. Steve is interrogated with the Lasso of Hestia and reveals that a great war is consuming the outside world and that he is an Allied spy. He has stolen a notebook of the chief chemist Dr. Isabel Maru, who is attempting to engineer a deadlier form of mustard gas under the orders of General Erich Ludendorff from a weapon facility in the Ottoman Empire. Believing Ares to be responsible for the war, Diana arms herself with the "Godkiller" sword, the lasso, and armor before leaving Themyscira with Steve to locate and stop Ares for good.
In August 2010 (issue #600), J. Michael Straczynski took over the series' writing duties and introduced Wonder Woman to an alternate timeline created by the Gods in which Paradise Island had been destroyed and the Amazons scattered around the world. In this timeline, Diana is an orphan raised in New York. The entire world has forgotten Wonder Woman's existence and the main story of this run was of Diana trying to restore reality even though she does not properly remember it herself. A trio of Death Goddesses called The Morrigan acted as the main enemy of Wonder Woman. In this run, Wonder Woman wears a new costume designed by Jim Lee. Straczynski determined the plot and continued writing duties until Wonder Woman #605; writer Phil Hester then continued his run, which ultimately concluded in Wonder Woman #614.
Unfortunately, not long after Diana left, Hera came for her vengeance, and though she could not bring herself to kill Hippolyta, she could not forgive her either. Feeling regret at giving up the only real family she had, Wonder Woman returned to Themyscira to find the Amazons absent, and her mother turned to stone. Shortly after, Wonder Woman encountered Lennox, a man who claimed to be another of Zeus' bastard children. After learning that Zeus has gone missing, they confronted the Gods of Olympus, Poseidon and Hades, in order to prevent them from taking over Zeus’ throne. To prevent a war between gods, Diana proposed that the two brothers share Heaven with one ruling during the day, and the other at night. Hera angrily interceded, which was what Diana had planned, and using Hermes' staff she transported herself to Mount Olympus to face Hera alone. She warned that she would make Hera regret what she had done to her mother before returning to Earth. Unfortunately, by the time she had returned, Hades had kidnapped Zola with the warning that Diana would need to make good on her bargain or Zola and her child would die.
