As Diana, Victor and Arthur all try to simultaneously flank Superman (albeit unsuccessfully), Barry attempts to help using his speed, but Superman is able to see him and keeps up with the speedster. Despite Barry's best efforts, Superman is able to land a glancing blow, knocking him out before Batman arrives and gets Superman to stop. Wonder Woman tries to fight Superman again, yet she's knocked down. He then swats Batman and asks him the same question that Bruce asked him "Tell me, do you bleed?". Before Superman could kill Bruce, Lois and Alfred to stop him.
The Diana Prince alias also played an important role after the events of Infinite Crisis. Wonder Woman was broadcast worldwide killing a villain named Maxwell Lord, as he was mind controlling Superman into killing Batman. When Wonder Woman caught him in her lasso, demanding to know how to stop Superman, Maxwell revealed that the only way to stop him was to kill Lord, so as a last resort Diana snapped his neck. To recover from the trauma of killing another person, the Amazon went into a self-imposed exile for one year. On her return to public life, Diana realized that her life as a full-time celebrity superhero and ambassador had kept her removed from humanity. Because of this she assumed the persona of Diana Prince and became an agent at the Department of Metahuman Affairs. During a later battle with the witch Circe, a spell was placed on Diana leaving her powerless when not in the guise of Wonder Woman.
Trevor pitched a mission to destroy the facility where the gas was being created, but his superiors decided against it, stating that it was too late in the war to do something as drastic as that. When Trevor argued that more soldiers would die, his superiors simply stated that that was what soldiers did. With the battle of Themyscira and the death of her aunt so fresh in her mind, Diana was infuriated by the man's comments and berated him, calling him a coward and telling the rest of the council that they should be ashamed. Trevor escorted her out as she ranted, apologizing to the council on her behalf.
As her injuries healed, Wonder Woman and her friends spent some time on New Genesis. She spoke to Highfather, who agreed to let her return to Earth. As soon as Diana and her friends returned to Earth, Orion decided to go with them. Arriving to London, they realized the First Born had wrecked the entire city and killed Lennox. The First Born summoned an army of hyena men to kill the intruders but Ares arrived to help Wonder Woman in the fight.
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.
