When Hippolyta and the other Amazons were trapped in a demonic dimension, she started receiving visions about the death of Wonder Woman. Fearing her daughter's death, Hippolyta created a false claim that Diana was not worthy of continuing her role as Wonder Woman, and arranged for a contest to determine who would be the new Wonder Woman, thus protecting Diana from her supposed fate. The participants of the final round were Diana and Artemis, and with the help of some mystic manipulation by Hippolyta, Artemis won the contest. Thus, Diana was forced to hand over her title and costume to Artemis, who became the new Wonder Woman and Diana started fighting crime in an alternate costume. Artemis later died in battle with the White Magician – thus, Hippolyta's vision of a dying Wonder Woman did come true, albeit not of Diana as Wonder Woman. Diana once again became Wonder Woman, a request made by Artemis in her last seconds. Artemis would later return as Requiem. Prior to Artemis' death, Hippolyta would admit to her daughter about her own part in Artemis' death, which strained their relationship as Diana was unable to forgive her mother for sending another Amazon to her death knowingly for the sake of saving her own daughter.
Wonder Woman was minorly associated with the series 52, and in the One Year Later universe following Infinite Crisis she becomes a member of the Department of Metahuman Affairs. The most memorable story arc from this era was the much maligned Amazons Attack story arc, which many fans felt was not engaging nor did it do enough service to the well-established characters. After Gail Simone took over the series, a number of memorable story arcs took place, foremost among them Rise of the Olympian and Warkiller. Following the departure of Gail Simone the character was relaunched into the storyline Odyssey, where she must discover who she is and what has happened to her life. During this period she also took part in the events of Blackest Night where she was first a Black Lantern and later a Star Sapphire.
During the fight, Steve approaches Diana who can't hear him speak due to an explosion temporarily rupturing her eardrums. Steve, after much talking, departs and leaves Diana with his watch before boarding the plane which is taking off with the mustard gas. Ares eventually restrains Diana, imploring her to surrender and realize the futility of their fight. Diana notices the plane in the sky as she's pinned to the ground and watches in horror as it explodes with Steve sacrificing himself to save billions of lives.
Following the events of Infinite Crisis, she disappeared for a year in order to rediscover herself, and took part briefly in the events of 52. In the span of One Year Later, she was re-imagined once again and was forgiven by Batman and Superman while given her third ongoing monthly title. Batman helped her establish a role at the Department of Metahuman Affairs under the name of Diana Prince (paying homage to her golden age alter ego.) She worked alongside Tom Tresser and eventually became romantically involved with him. A move among fans across the different companies occurred with characters reverting to their original numbering of series (this for instance happened to Iron Man at Marvel as well) and the third Wonder Woman series was relaunched with Wonder Woman #600. This was actually accurate at the time as it was the indeed the 600 issue released (not including issues numbered otherwise such as with a zero or a million). Issue 600 was used as a chance to reinvent the character as she discovers herself with no memories and in a new costume. This was a short lived experiment as the entire DC lineup was soon to be re-imagined into the new 52, though certain aspects of her redesigned costume remained.
