The Greek messenger god, Hermes, entrusts Wonder Woman with the protection of Zola, a young woman, who is pregnant with Zeus's child, from Hera, seething with jealousy and determined to kill the child. With the appearance of a bizarre, new, chalk-white enemy, the goddess Strife (a reimagined version of Eris, the goddess of discord who had battled Wonder Woman in post-Crisis continuity), Wonder Woman discovers she, herself, is the natural-born daughter of Hippolyta and Zeus, who, after a violent clash, became lovers. Hippolyta revealed Diana's earlier origin story to be a lie, spread amongst the Amazons to protect Diana from the wrath of Hera, who is known for hunting and killing several illegitimate offspring of Zeus.
Using Bruce's equipment, Diana tries to track down Victor. Victor is aware of Bruce's interest in him; due to his connection to information and security systems, Victor hacks in the computers to send Diana a message. Diana suggests a meeting and when Victor asks why he should trust her, Diana tells him that she knew he was at the lake watching her and Bruce. If she meant to harm him, she would have done it then. Diana and Victor meet face to face, and he tells them that the invaders they are searching for are hiding in the dead zones. When Diana tries to convince him to join them, he flies off.
Not long after this, Athena sensed a dark destiny for the gods amidst the cosmic mechanations of Alexander Luthor Jr.. In the crisis created by his chaos, Diana was forced to kill Maxwell Lord, and incurred the ire of the world's public. The U.S. government responded by mobilizing against Themyscira, and Diana realized that as long as she was a target, the Amazons would never be safe. Diana prayed to the gods to take the Amazons to safety, but got more than she bargained for. On Olympus, she pleaded against Athena's decision to remove the gods from Earth's affairs. Regardless, the gods departed, leaving Diana bereft of family and faith.
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.
During a training session observed by Hippolyta, Diana sparred against her fellow warriors, demonstrating her weapons expertise and defeating each of them swiftly. Her final opponent was Antiope herself. The two fought with all their might. Diana managed to disarm Antiope and looked toward her mother for approval. Antiope seized the opportunity to push Diana to the ground and pick up her sword, admonishing her for letting her her guard down. As Antiope slashed at her and forced her backwards, Diana instinctively brought her arms together to block the attack. She clashed her arm gauntlets together, resulting in her unleashing a powerful shock-wave that sent Antiope flying back and left all spectating Amazons there, including Diana herself, in complete shock.
Later in the story, Wonder Woman is locked in a cell. Straining to overhear a conversation in the next room, through the amplification of “bone conduction,” she takes her chain in her teeth: “Closeup of WW’s head shoulders. She holds her neck chain between her teeth. The chain runs taut between her teeth and the wall, where it is locked to a steel ring bolt.”
Even alongside all of her kindness, compassion, and empathy, Diana is still also a warrior at heart, and when someone she cares about is hurt, becomes far more relentless and ruthless. When seemingly beaten by Ares (who was only growing more powerful from her violence, rage, and hatred), and after having to watch her beloved Steve Trevor die, she flew into an agonizing rage, and she assaulted and brutalized several armed German soldiers with immense speed and ferocity. She even came close to murdering Dr. Poison as vengeance for Steve's death; but after recalling Steve's great love for an undying belief in her and her beliefs, restrained herself and refocused her energies on Ares, harnessing her love for Trevor to overcome her violent emotions and swiftly overpower an angered Ares. Additionally, she resolved to fight even harder after Steppenwolf revealed that he had killed several other Amazons. Outside of battle, however, Diana can also react indigently and negatively towards people who disrespect her, her relatives, or those she cares about. Two such notable instances were when she shot an angry look at Lex Luthor (after he insulted her father Zeus's memory), and when she shoved back Batman (after he had insulted her beloved Steve Trevor's memory). Diana also remains ruthless when facing enemies in battle as Wonder Woman, and she even shows signs of enjoying a good battle when they put up a good fight. This was seen when she briefly smiled and laughed when she was beaten to the ground by Doomsday, and smirked as she stopped the first bullet fired at a group of hostages in London.
Mikos delivers Ventouras's dead son to him, presumably killed by the rebel faction. This causes him to seek revenge against the Rebels and Diana. They turn into monsters and attack Diana. Diana fights the witch's forces but is overpowered by the witch herself, but only after retrieving the scroll from Stavros who was already attacked and severely wounded. The scrolls ends up in Julia's hands, and she immediately goes to work decoding it in an effort to save Diana and discover the witch's weakness. Diana is taken to the witch's stronghold, where she is revealed to be Circe, a sorceress possessing the soul of Hecate, the moon god after they had entered into a pact to drive the world into chaos. She tells Diana what became of her aunt Antiope, who was killed by Circe herself after manipulating Antiope's husband Theseus's former wife. Circe explains to Diana that her existence is a threat to her mission, due to Diana's goal of promoting peace and equality among mankind, and therefore she must be eliminated. Circe is about to kill Diana when she is interrupted by Julia and the rebels. Julia had decoded the scroll and knew how to stave off the witch's attacks. But they are beaten by Circe and almost killed when Circe herself is suspiciously summoned off from the island by an unknown force, later revealed to be the god Hermes.
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.
While Superman watched out for Zod, Diana visited the deserted Themyscira to speak to her mother, still a clay statue. In her absence, a demon from Tartarus had escaped from its prison and roamed free on the island. Wonder Woman destroyed the creature and sealed the gates to Tartarus with her lasso. Leaving the island, she received word from Batman that Superman was engaging Zod and Faora in battle. Reaching Superman’s side, Wonder Woman steadily overwhelmed Faora until Zod threatened Superman’s life. Wonder Woman was forced to let the criminals go.
