The New 52 universe does not have a "Diana Prince" identity as stated in an interview by series writer Brian Azzarello. However, when she and Superman began dating, for her civilian identity she used the Diana Prince alias whenever she was around Clark Kent; such as when she introduced herself to Lois Lane at Lois's housewarming party under that name.
The Crime Syndicate imprisoned the Justice Leagues inside the Firestorm Matrix which psychologically placed them in situations that depicted their greatest failures. Wonder Woman was placed in a situation where she was forced to do battle against both Amazons and humans for the lives of Superman and Steve Trevor. Martian Manhunter and Stargirl attempted to break her out but Wonder Woman ignored them.

In October 1940, the popular women's magazine "Family Circle" published an interview with Marston entitled "Don't Laugh at the Comics," in which the psychologist discussed the unfulfilled potential of the medium.
After Crisis on Infinite Earths, the character’s origin was slightly retold by Greg Potter and George Perez. In this version, the Amazons were reincarnations of the souls of abused and murdered women from ancient days. In 1200 B.C. a debate occurred on Mount Olympus on how mankind should be made to relate to the gods. Ares, the god of war and destruction, wanted to descend upon the world with his army and crush mankind submission. This was opposed by the others gods present including Artemis, who wanted peace and suggested creating a new race that would lead humans on the right path. Zeus rejected their arguments, and they decided to proceed without his blessing. With the aid of Charon the ferryman, the gods reached the Womb of Gaea, where the souls of women who were abused and murdered at the hands of men were preserved by Gaea herself. Artemis then sent the souls to Greece where they reincarnated into adult women. Aphrodite observed that one soul still remains in the Womb, to which Athena replied that the time had not yet come for that one. The new race in Greece were approached by the goddesses, who bestowed upon them several blessings, charging them with the purpose of leading humanity in the ways of Gaea. They then appointed Hippolyte and Antiope as co-rulers. The civilization is named the Amazons. Stories of this civilization spread throughout Greece and reached the ears of Heracles, who was being manipulated by Ares into attacking the Amazons. Heracles approached the Amazons but was defeated by Hippolyte, upon which he pretended friendship and declared the Amazons allies. When their guard was down, the Greeks drugged the Amazons, taking Hippolyte, Antiope and the other survivors captive. In her cell, Hippolyte is freed by Athena ,who reminds her of her purpose and asked her to avoid revenge and pursue peaceful means. Hippolyte escaped and freed the rest of the Amazons. She shared Athena's message to the Amazons, but blinded by their thirst for revenge, they ruthlessly slaughter the remaining men. Antiope gave Hippolyta her girdle and left to pursue revenge The goddesses appeared and told them they had failed in their purpose and banished them to an island to guard the terrible evil within, as penance. They were granted immortality as long as they did not stray from their new purpose, which would eventually purify their souls. The Amazons built a nation and lived there for 4,000 years. It is during this time that Hippolyte, sole leader of the Amazons, felt an unexplained yearning. Menalippe, the Oracle, told her she was the only Amazon pregnant at the time of her previous incarnation's death, and thus the yearning she felt was the call of her unborn child. As per her advise, Hippolyte went to the shore at sunrise and made a clay figure of a baby. She then cried out to Artemis. The gods, recognizing it was time for the remaining soul in Gaea's womb to depart, infused it into the clay form, which then incarnated as a real child. Blessed with Gaea's greatest gift, life, the gods present bestowed their gifts upon the newborn: Demeter granted the baby great strength, Aphrodite granted her great beauty and a loving heart, Athena granted her great wisdom, Artemis granted her the eye of the hunter and unity with beasts, Hestia granted her sisterhood with fire, and Hermes gave her great speed and the power of flight. Hippolyte named her after a holy warrior, Diana, and she grew up knowing the love of a thousand mothers. Thus Diana of Themyscira was born.
Gaines didn’t know any of this when he met Marston in 1940 or else he would never have hired him: He was looking to avoid controversy, not to court it. Marston and Wonder Woman were pivotal to the creation of what became DC Comics. (DC was short for Detective Comics, the comic book in which Batman debuted.) In 1940, Gaines decided to counter his critics by forming an editorial advisory board and appointing Marston to serve on it, and DC decided to stamp comic books in which Superman and Batman appeared with a logo, an assurance of quality, reading, “A DC Publication.” And, since “the comics’ worst offense was their blood-curdling masculinity,” Marston said, the best way to fend off critics would be to create a female superhero.
The First Born imprisoned Wonder Woman in what remained of Olympus and ordered his forces to attack Themyscira. As they watched the confrontation, the First Born offered her a place in his goals of conquest, but she steadfastly refused, causing him to thrust a spike into her side. As Diana lied mortally wounded, Eris dragged her to Themyscira, for she wanted Diana to see her home destroyed and humiliate her. Recovering her strength, Wonder Woman punched Eris down and took Zola and Zeke to Olympus. Her plan was to place Zeke on the throne, so that he could be the new king of Olympus and end the bloodshed, but before she could, Poseidon revealed his presence.
