Orion tells Diana that he was sent to earth to fight a threat, and surprised that the possible threat he faces is a mere child. They find out that Zola's baby is being kept with Hermes, who in turn is hiding in Demeter's realm. Going back to the hotel to regroup, they find Zola and Hera missing. Finally finding them in a bar, Diana comes face to face with War, her old master.
In the New 52, the night when she turned 8, Ares appeared before Diana and offered to train her above and beyond the abilities of the Amazons, having seen her potential to eventually become his replacement as the God of War. Though the training was one for one night each month, the year was noticed with Diana improving tremendously compared to the other Amazons.
Wonder Woman's signature weapon was her Lasso of Truth; consequently, much of her crime-fighting powers came from bondage, and her only exploitable weakness was, essentially, bondage. Grant Morrison and Yanick Paquette had teamed up to work on Wonder Woman: Earth One. Paquette confirmed that he and Morrison would be bringing back the bondage theme that was popular in Wonder Woman comics during the 1940s. However, he stated that Morrison was looking for a way to not only modernize it, but to use the bondage theme as a form of female empowerment. Paquette acknowledged that Wonder Woman has become more than just a beloved character, she is a symbol for feminism. "By bringing in sex and, yes, bondage, it reasserts [William Moulton Marston's core] idea that it is okay for women to have a healthy sexual appetite." Paquette elaborated more on this by pointing out the blatant double standards in comics when it comes to sex: "Could Wonder Woman really ever have a healthy and active sex life without it becoming political fodder for Fox News? And what of women and girls who want to be like her? Do we truly think they wouldn't be labeled sluts? I have my doubts."
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.
Issue #600 introduced Wonder Woman to an alternate timeline created by the Gods in which Themyscira had been destroyed and the Amazons scattered around the world. In this timeline, Diana is an orphan raised in New York who is learning to cope with her powers. The entire world has forgotten Wonder Woman's existence and the main story of this run was of Diana trying to restore reality even though she does not properly remember it herself. Diana has no memories of her prior adventures as Wonder Woman, recollecting her memories in bits and pieces and receiving different abilities and resources (such as the power of flight and her lasso) during the progression of her adventure. A trio of Death Goddesses called The Morrigan acted as Wonder Woman's main enemies. Diana ultimately defeats the evil goddesses and returns everything back to normal.
Throughout Diana's childhood, she was training and sparring with her Amazonian sisters. One day when pilots were test flying, one of the pilots called Steve Trevor, has an accident with his plane, and Hippolyta opens Themyscira's shields and disguise, and Steve Trevor lands his plane on Paradise Island. Steve then proceeds to explore the island, and that's where he finds beautiful women bathing, but while staring at the women, Diana surprises him from behind and takes him out by kicking him in his testicles. Steve is then strapped up because of Hippolyta keeping him safe until someone proves worthy enough to escort him back to the USA. Wonder Woman while covered in a helmet, wins the challenges and gets to escort Steve back home, but while the challenges were going on, a traitor in the Amazons freed Ares because she loved him. Ares is free, and he goes to Hades so he could remove the bracelets blocking his powers.Throughout being in USA, Diana also tries to stop Ares' plans as Wonder Woman, but she fails the first time, and Ares gets ahold of the power he was searching for. After calling in his army, the US finds an island that appeared out of nowhere on the map, that being Paradise Island. They set off a nuke towards Paradise Island, and Steve manages to stop it, and at the same time, Wonder Woman defeats Ares with help from her Amazonian sisters. She realizes her feelings for Steve, and she kisses him, but when being back in Paradise Island, she looked sad. Hippolyta allowed her to operate in the outside world where she shared her feelings and her life with Steve.
Wonder Woman's social reforms were not initially accepted by the Amazons, even if they were morally necessary. Later, she had a training session with Artemis, who urged her to accept the Amazons' worship as a goddess, but Diana refused. Unfortunately, Dessa, a fellow Amazon, kidnapped Zeke and threatened to throw him off a cliff, for she disagreed with Diana's new perspective. Diana convinced her to return the boy to Zola. Shortly afterwards, the men of Paradise Island returned to their original home, with Diana welcoming them with open arms.
Coming to America for the first time, Wonder Woman comes upon a wailing army nurse. Inquiring about her state, she finds that the nurse wanted to leave for South America with her fiancé but was unable due to shortage of money. As both of them looked identical and Wonder Woman needed a job and a valid identity to look after Steve (who was admitted in the same army hospital), she gives her the money she had earned earlier to help her go to her fiancé in exchange for her credentials. The nurse reveals her name as Diana Prince, and thus, Wonder Woman's secret identity was created, and she began working as a nurse in the army.
