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.
Wonder Woman has been the subject of a discussion regarding the appearance and representation of female power in general, and of female action heroes in particular since her initial 1941 appearance in Sensation Comics, as she was created to document "the growth in the power of women", while wearing "a golden tiara, a red bustier, blue underpants and knee-high, red leather boots." She was blacklisted a year later in 1942 in the "Publications Disapproved for Youth" because, the group behind the list argued, she was "not sufficiently dressed".
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.
The New 52 version of the character has been portrayed to be a younger, more headstrong, loving, fierce and willful person. Brian Azzarello stated in a video interview with DC Comics that they're building a very "confident", "impulsive" and "good-hearted" character in her. He referred to her trait of feeling compassion as both her strength and weakness.
In the first story arc, Wonder Woman meets and protects a young woman named Zola, from Hera's wrath. Zola is pregnant with Zeus's child and Hera, seething with jealousy intends to kill the child.   The major event in this story is the revelation of Diana's true parentage. Long ago, Hippolyta and Zeus battled each other. Their battle ended with the couple making love and thus Diana was conceived. The first six issues of the New 52 series are collected in a hardcover titled Wonder Woman Vol. 1: Blood.
At the time of her debut, Wonder Woman sported a red top with a golden eagle emblem, a white belt, blue star-spangled culottes, and red and golden go-go boots. She originally wore a skirt; however according to Elizabeth Martson, "It was too hard to draw and would have been over her head most of the time." This outfit was entirely based on the American flag, because Wonder Woman was purely an American icon as she debuted during World War II. Later in 1942, Wonder Woman's outfit received a slight change – the culottes were converted entirely into skin-tight shorts and she wore sandals. While earlier most of her back was exposed, during the imposition of the Comics Code Authority in the mid-1950s, Wonder Woman's outfit was rectified to make her back substantially covered, in order to comply with the Authority's rule of minimum exposure. During Mike Sekowsky's run in the late 1960s, Diana surrendered her powers and started using her own skills to fight crime. She wore a series of jumpsuits as her attire; the most popular of these was a white one.
Suddenly, Zola and the others were attacked by Artemis, who was sent by Apollo to kill Zeke, Zola's son. While Zola and the others escaped with Zeke, Wonder Woman took on Artemis by herself. Diana defeated Artemis and went to protect Zola and the others, while Ares took the defeated Artemis back to Apollo. However, the First Born and Cassandra, two of Zeus' illegitimate children, attacked Zola. Wonder Woman, Lennox and Orion worked together to fight the First Born, but he proved to be stronger than they had anticipated. Orion's Astro Harness incapacitated Cassandra, and Orion opened a Boom Tube so that Wonder Woman and her allies could escape. The First Born attempted to pry the Boom Tube open, but Lennox sacrificed himself so that the others could escape safely. Wonder Woman and her allies arrived at the other side of the Boom Tube and were greeted by Highfather, who explained that they were on New Genesis.
A warning that is first heard from the lips of Cheetah as she attempts to escape captivity, yet is echoed by others around the globe, all putting Wonder Woman on alert. As she attempts to investigate, she is attacked by Supergirl, wanting vengeance for the death of Rao, as the influence has gotten to her as well. An epic battle breaks out, and once again, the trusty Lasso of Truth saves the day, though barely.
When Marston died in 1947 Robert Kanigher took over and Diana became less of a feminist character but during this time, her abilities expanded as she wore earrings that provided her with the air she needed when she was in outer space and she had an invisible plane. Extra additions included a tiara which could cut through almost anything and acted as a boomerang and her bracelets now had two way radios.
“Of course I wouldn’t expect Miss Roubicek to understand all this,” Marston wrote Gaines. “After all I have devoted my entire life to working out psychological principles. Miss R. has been in comics only 6 months or so, hasn’t she? And never in psychology.” But “the secret of woman’s allure,” he told Gaines, is that “women enjoy submission—being bound.”
In one episode, a newspaper editor named Brown, desperate to discover Wonder Woman’s past, assigns a team of reporters to chase her down; she easily escapes them. Brown, gone half mad, is committed to a hospital. Wonder Woman disguises herself as a nurse and brings him a scroll. “This parchment seems to be the history of that girl you call ‘Wonder Woman’!” she tells him. “A strange, veiled woman left it with me.” Brown leaps out of bed and races back to the city desk, where he cries out, parchment in hand, “Stop the presses! I’ve got the history of Wonder Woman!” But Wonder Woman’s secret history isn’t written on parchment. Instead, it lies buried in boxes and cabinets and drawers, in thousands of documents, housed in libraries, archives and collections spread all over the United States, including the private papers of creator Marston—papers that, before I saw them, had never before been seen by anyone outside of Marston’s family.
