Wonder Woman actress Gal Gadot reacted positively to Diana's rebooted orientation, and agreed her sexuality was impacted by growing up in the women-only Themyscira. Gadot stated that Wonder Woman feels she need not be "labelled sexually", and is "just herself". "She's a woman who loves people for who they are. She can be bisexual. She loves people for their hearts." Coming from a society that was only populated by women, "'lesbian' in [the world's] eyes may have been 'straight' for them." "Her culture is completely free from the shackles of heteronormativity in the first place so she wouldn't even have any 'concept' of gender roles in sex."
In the following days, Diana soon uncovered Ares, who exposed her to be the God Killer, having been originally conceived to be the ultimate weapon against her brother. Following this revelation, a fierce battle ensued, where Diana fulfilled her purpose in freeing mankind from Ares' influence. The loss of Steve in World War I had left Diana sobered, but she vowed to protect humanity whenever she was needed, albeit in a cautious and distant way.
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.
