A stand-alone #0 issue was released in September which explored Diana's childhood and her tutelage under Ares, the God of War, now known most often as simply 'War'. The issue was narrated in the style of a typical Silver Age comic book and saw Diana in her childhood years. The main plot of the issue was Diana training under War as he thought of her being an extraordinary girl with immense potential. The issue ultimately concluded with Diana learning and experiencing the importance of mercy, which she first learned when War showed it to her during their sparring. This later translated into her refusal to kill the Minotaur – a task given to her by War; however, this show of mercy makes her a failure in War's eyes, which was actually his fault since he inadvertently "taught" her mercy and affection as his protege. Later in the series, Wonder Woman is forced to kill War during a conflict with her evil half-brother, Zeus' son First Born, and herself becomes the God of War. After the Amazons are restored, she rules over them both as a warrior queen and God of War, as the ongoing conflict with First Born escalates. At the end of Azzarello's run, as part of a final conflict, Wonder Woman kills First Born, while Zeke is revealed to have been Zeus' plan for resurrection, with Zola revealed to have been a mortal shell for the goddess Athena, who gave birth to Zeus just as he once did to her. Wonder Woman pleads with Athena not to allow the Zola personality, whom she has grown to love as a friend, die with Athena's awakening. Athena leaves the site in animal form, leaving a stunned and confused Zola behind with Wonder Woman.
In order to defeat them, Superman and Wonder Woman collected the magic armor created by Hephaestus and intercepted Zod and Faora while they were building a portal to the Phantom Zone. At first, they defeated Zod and Faora by detonating their armor at point-blank range, but Zod and Faora were revitalized by a beam of sunlight sent by Apollo, which gave the criminals enough strength to beat Superman and Wonder Woman and trap them in an abandoned nuclear reactor. As a last-ditch effort to stop their enemies, Superman and Wonder Woman caused a nuclear explosion, but not before Clark told Diana that he loved her. The explosion trapped Zod and Faora back in the Phantom Zone, and Superman shielded Wonder Woman with his cape. The two heroes barely survived the explosion and Superman took Diana to Hessia, who used a healing crystal to save her.
Arriving at Chernobyl, Wonder Woman, Orion, Siracca and Hermes engaged Cassandra's forces to save Milan. Cassandra threatened to kill Milan if Wonder Woman did not reveal the First Born's location. Wonder Woman told her the First Born was in Olympus, but as she left, Cassandra strapped a bomb to Milan's chest. To contain the explosion, Orion took Milan through a boom tube. Returning home, Wonder Woman discovered Zola and Zeke had left, as Zola felt guilty that people were risking their lives to protect them.

Wonder Woman's advocacy for women rights and gay rights was taken a step further in September 2016, when comic book writer Greg Rucka announced that she is canonically bisexual, according to her rebooted Rebirth origin. Rucka stated, "... nobody at DC Comics has ever said, [Wonder Woman] gotta be straight. Nobody. Ever. They've never blinked at this." Rucka stated that in his opinion, she "has to be" queer and has "obviously" had same-sex relationships on an island surrounded by beautiful women. This follows the way Wonder Woman was written in the alternate continuity or non-canon Earth One by Grant Morrison, and fellow Wonder Woman writer Gail Simone staunchly supported Rucka's statement. Surprised at the amount of backlash from her fanbase, Rucka responded to "haters" that consensual sex with women is just as important to Wonder Woman as the Truth is to Superman.
