After a training session, Diana happened to come across Captain Steve Trevor during his escape from the Imperial German Army. A battle soon followed, as the Germans tracked Trevor to Themyscira, where they invaded in pursuit of Doctor Poison's notes. The loss of her aunt and realization of Mankind's downfall during the absence of the amazons convinced Diana to join the war effort, recognizing Ares as the instigator of the conflict.

Princess Diana commands respect both as Wonder Woman and Diana Prince; her epithetical title – The Amazon Princess – illustrates the dichotomy of her character. She is a powerful, strong-willed character who does not back down from a fight or a challenge. Yet, she is a diplomat who strongly "favors the pen", and a lover of peace who would never seek to fight or escalate a conflict. She's simultaneously both the most fierce and most nurturing member of the Justice League; and her political connections as a United Nations Honorary Ambassador and the ambassador of a warrior nation makes her an invaluable addition to the team. With her powerful abilities, centuries of training and experience at handling threats that range from petty crime to threats that are of a magical or supernatural nature, Diana is capable of competing with nearly any hero or villain.
Meanwhile, the New God Orion had learned that a great danger was to be found on Earth in the form of the child of a god. He sought out his old friend Milan for help. Nearby, Diana and Lennox decided to seek Milan by themselves, leaving Zola and Hera to bicker with one another in the meantime. They found him in the old subway system with Orion. Though their encounter began violently, Lennox managed to explain that they had accounted for six of the seven children of Zeus. Orion believed that one of those seven was the child that he had been sent to kill. Lennox and Diana concluded that he was referring to Zola's kidnapped son, and so they convinced Milan to search through the ether until he located the boy in the arms of Demeter. When they all returned to Manhattan to find Zola and Hera in a bar with War, Diana managed to convince her uncle to lead her to Demeter's domain.
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.
