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.
As the men helped the Amazons prepare for battle against the First Born's army, Diana received news that the First Born had been attacking other gods' realms. With Eros and Artemis, Wonder Woman ambushed the Minotaur at Demeter's home. Unfortunately, the First Born had already defeated Demeter, so Wonder Woman sent her companions to safety while she confronted him by herself.
Invisible Plane: Wonder Woman possesses an airplane capable of rendering itself completely invisible to the human eye. Like her bracelets, Diana's invisible plane is forged with Eighth Metal, making it almost indestructible. The Invisible Plane was originally the aircraft Steve Trevor crashed onto Themyscira; it was repaired by the Amazons and upgraded with their technology.
After, she encounters Apollo and Artemis. A fight ensues while lead to the capture of Zola. Using Hermes caduceus, they teleport to Olympus and the following events occur: Hermes gives Diana the ability of flight after poking her with a mystical feather, and two, Diana shows off her "God Mode" off to the goddess Artemis, revealing that taking off her bracelets augments her strength.
The American theme of Diana's costume was explained by Pérez in the Challenge of the Gods storyline in which Diana engaged in a series of trials arranged by Zeus as punishment for refusing his advances. Diana met the spirit of Steve Trevor's mother, Diana Trevor, who was clad in armor identical to her own. Trevor revealed that during World War II she had crashed on Themyscira while on duty as a U.S. Army pilot. She blundered into an Amazon battle against Cottus, a multi-armed demon, at the portal to the underworld. Trevor was drawn into the battle, although she was armed only with her side arm. She wounded the beast before suffering a mortal blow, allowing the Amazons to reseal the portal.
With Zola's pregnancy reaching full term, she insisted on seeing her own doctor in Michigan. While there, they were all attacked by Artemis and Apollo. Unprepared, Diana and her companions were defeated, and Zola was taken to Mount Olympus to be delivered to Hera in exchange for the throne. Apparently, Hera was willing to give up her throne for the sake of revenge. However, she had expected Zeus to return as soon as his rule was threatened, which he did not. When Apollo sat on the throne, he was crowned ruler, and when he learned of Hera's deceit, he exiled her from Olympus.
I remember when I read in the news that Wonder Woman had been cast and my heart sank ... I'm sure we wouldn't have made the same choice. And then I started paying attention to her, and watching her and looking at her and it was just unbelievable. Frankly, I think they did a better job than I could have because I don't know that I would have scoured the earth as hard to find her ... They were looking for all the same things I would have looked for—all the values that Wonder Woman stands for exuding from someone in an honest way, and boy did they find it ... She shares every quality with Wonder Woman and that's no joke. It's one of those rare things. You need someone who can appear to be Wonder Woman on screen ... Every once in a while, there's superhero casting that transcends, because that person is so authentic to the character that it becomes identified with them, like Lynda Carter or Christopher Reeve.
Wonder Woman and the other heroes were finally released from the Firestorm Matrix when Batman used the Lasso of Truth on Firestorm. Superman was still infected with the Kryptonite shard inside his nervous system, but Lex Luthor was able to extract it, saving Superman's life. Luthor also assembled a group of villains that defeated the Crime Syndicate. Later, at the Batcave, Wonder Woman and the Justice League talked about the enemy that destroyed the Crime Syndicate's world and came to the conclusion that Darkseid would return.
Wonder Woman's supporting characters were altered as well. In addition to the introduction of the Kapatelises, Steve Trevor was changed into an Air Force officer considerably older than Diana, thus sidestepping the traditional romance between the two. Instead, Trevor became involved with Etta Candy, a mature military officer possessing a plump physique. The Greek war god Ares and the witch Circe eventually became two of Diana's greatest enemies. Her rogues gallery included the Cheetah, a woman who could transform into a ferocious feline-humanoid creature; and the Silver Swan, a once-deformed radiation victim granted beauty, wings and deafening sonic powers through genetic engineering.
While living in "Man's World" for a century following World War I tempered some of Diana's more blindly held beliefs, she still held true to her core values of kindness and compassion, and further grew into an exceptionally considerate, diplomatic, and empathetic woman. This can be seen when she silently emphasizes with Lois Lane after the death of Superman had been killed (recalling her own pain after Steve Trevor's sacrifice), smiling knowingly when Aquaman accidentally sat on the Lasso of Hestia and confessed his fears about their upcoming mission and how attractive he found her. With all of her experiences, Diana is also the most diplomatic member of the Justice League, as evidenced by her treatment of the Flash with compassion and patience, despite his tendency to somewhat annoy her and the other Justice Leaguers with his humorous attitude, and the kindness and support she showed to Cyborg while he continued to grapple with his powers. Indeed, through her compassion and unbreakable spirit, Diana has given renewed hope to many of her teammates throughout the years. For example, she motivated and inspired the Wonder Men into looking past purely monetary interests, with Chief resolving to no longer be neutral in the war, Sameer finally admitting his passion for acting, and even the depressed Charlie struggling with PTSD finally beginning to sing again for the first time in years. Likewise, during the Justice League's battle against Steppenwolf's forces, Wonder Woman was able to inspire confidence in the inexperienced Flash and Cyborg, assuring them that they wouldn't need to fight the Apokoliptan invasion alone. Furthermore, she was the most understanding of Superman's confusion upon his ressurrection and remained ambivalent about fighting the newly-resurrected Superman and even implored him not to force her to, showing him compassion and persistence while attempting to get him to remember who he is (even calling him by his birth name). In addition to her general willingness for empathy, however, Diana is also extremely friendly and can step back enjoy the smaller moments in life, as seen in her utter delight in experiencing ice cream and agreement with Superman (who, up until this point she had not spoken to much) about him not missing out on the positive results of their victory over Steppenwolf.
Marston was an outspoken feminist, swinger, and firm believer in the superiority of women. He described bondage and submission as a "respectable and noble practice". Marston wrote in a weakness for Wonder Woman, which was attached to a fictional stipulation that he dubbed "Aphrodite's Law", that made the chaining of her "Bracelets of Submission" together by a man take away her Amazonian super strength.
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.
