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.
With the appearance of the Bana-Mighdallian Amazons, the Olympians faced a new prospect. Though devout Amazons, these newest citizens of Themyscira do not worship the Greek gods. Renouncing them millennia ago, the tribe instead worship a combination of Egyptian and middle eastern deities. The central gods worshipped by the desert Amazons are: Isis (wisdom and magic), Mammitu (judgement bringer), Bast (nature and feminine), and Neith (mother figure and protection). These gods followed the Bana-Mighdallian Amazons to Themyscira where they continued to be worshipped. Facing the situation with hands tied, both pantheons agreed to integrate themselves with each other for the benefit of their people. Though these new gods do not reside on Olympus, they are treated with diplomacy when called to aid the Amazons in a united godly role. Despite the gods mentioned being part of the inner-circle of deities in the Bana's belief system, less significant gods have been shown to be part of their godly pantheon as well such as Sekhmet (war god), Thoth (their only known male god) and possibly Ishtar (love goddess). The gods of Bana-Mighdall proved their loyalty to the Olympians by aiding the Greek gods in battle when the war gods Sekhmet and Ares previously devised a coup on Olympus.
The New 52 version of the character has been portrayed to be a younger, more headstrong, loving, fierce and willful person.

He referred to her trait of feeling compassion as both her strength and weakness.
A fight broke out among the heroes for possession of the box and was only ended when John Constantine took the box, being the only one capable of doing so without being corrupted. Zatanna and Constantine took the box to the temple of Hephaestus, where the three Justice Leagues had converged again. After yet another battle between heroes, the box went dormant and the Justice Leagues discovered a Kryptonite sliver in Superman’s nervous system, placed there by the Atomica, a traitor working for the Outsider, leader of the Secret Society. Then, the Outsider used the box to open a path across universes, allowing the Crime Syndicate to enter the Justice Leagues' world.
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.
In 1954, Dr. Fredric Wertham alleged that there were lesbian subtexts to Wonder Woman and claimed comics contributed to juvenile delinquency in his book Seduction of the Innocent where despite a very obvious heterosexual relationship with Steve Trevor, Wertham asserted that Wonder Woman’s association with the Holliday Girls could be interpreted as a lesbian relationship. The Comics Code Authority was then introduced in reaction to Wertham 's claims against the entire industry.
