In August 2010 (issue #600), J. Michael Straczynski took over the series' writing duties and introduced Wonder Woman to an alternate timeline created by the Gods in which Paradise Island had been destroyed and the Amazons scattered around the world. In this timeline, Diana is an orphan raised in New York. 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. A trio of Death Goddesses called The Morrigan acted as the main enemy of Wonder Woman. In this run, Wonder Woman wears a new costume designed by Jim Lee. Straczynski determined the plot and continued writing duties until Wonder Woman #605; writer Phil Hester then continued his run, which ultimately concluded in Wonder Woman #614.
Despite helping win the war, defeating Ares and still loving humanity, Diana is still left sobered, emotionally broken, psychologically scarred, and devastated over not having been able to save the Belgian village from Dr. Poison, as well as over her beloved Steve Trevor's self-sacrificing death. Indeed, Diana would later claim that she "would never be the same" ever again after World War I. Moreover, in the years that followed, Diana bore witness to a "century of horrors" (Wars, Fascism, Communism, nuclear weapons' deployment, geopolitical brinkmanship, racism, homophobia, genocides, war crimes, propaganda, and etc.), and due to all of this occurring without Ares being there to spread corruption, Diana almost completely lost faith in humanity, coming to believe that humans "made a world where standing together is impossible". As such, Diana resolved to mostly abandon superheroism for 100 years.
Due to the format of most golden age comics, the majority of story arcs at the time for all characters were the same, Wonder Woman included. More accurately that is to say that there were not story arcs at all, as issues contained two to three stories, all of which started and concluded within the issue in question. There was therefore not much continuity in Wonder Woman until she reached the silver age. The few exceptions to this were in issues which contained a common theme, such as Wonder Woman meeting some leprechauns and each of the three stories dealing with that. Alternately there were some common themes for the character at the time, one of which was dealing with enemy saboteurs. These were mostly contemporary, and thus started as either the National Socialists in Germany or the Imperial Japanese. Later these became others.
Diana lifts a tank ready to crush Doctor Poison with it, but hesitates when she thinks about the love and compassion that Steve brought to her life when she realizes that he professed his love for her before leaving to sacrifice himself. Dropping the tank, Diana spares Doctor Poison, telling Ares that he is wrong about humanity. She tells him that while humans are everything Ares says and can be capable of the worst crimes, she's learned that they are equally capable of so much more: unbridled love and compassion. Ares engages Diana in a final fight, but is defeated after she fully embraces her powers as the God Killer and blasts Ares with powerful divine lightning. The soldiers, free from Ares' corruption, stop their fighting, thereby finally ending the war.
This section of the history takes place during the New 52, between the events of Flashpoint and DC Rebirth. It was later revealed that much of Wonder Woman's history from this time was an elaborate illusion created by the Gods of Olympus to keep her away from Paradise Island. All or part of this section may have been part of that illusion and no longer valid in Rebirth.
If you're looking for a certified God of War on a personal vendetta against a pantheon of gods, Wonder Woman has you covered. The current version of Diana hacking and slashing her way through the DC Universe, anyway. After unintentionally bringing a new collection of "Dark Gods" into the comic book universe, it falls to the daughter of Zeus to save Earth from their malice.
Diana's bulletproof bracelets were formed from the remnants of Athena's legendary shield, the Aegis, to be awarded to her champion. The shield was made from the indestructible hide of the great she-goat, Amalthea, who suckled Zeus as an infant. These forearm guards have thus far proven NIGH-indestructible (the Omega Beams of Grail have proven able to shatter them), and are able to absorb the impact of incoming attacks, allowing Wonder Woman to deflect automatic weapon fire and energy blasts. Diana can slam the bracelets together to create a wave of concussive force capable of making strong beings like Superman's ears bleed. Recently, she gained the ability to channel Zeus's lightning through her bracelets as well. Zeus explained to her that this power had been contained within the bracelets since their creation, because they were once part of the Aegis, and that he had only recently unlocked it for her use. After the 2011 relaunch of the character, it was revealed that Diana was the daughter of Zeus and Hippolyta and that the bracelets are able to keep the powers she had inherited from Zeus in check. In addition, Hephaestus has modified the bracelets to allow Wonder Woman the sorcerous ability to manifest a sword of grayish metal from each bracelet. Each sword, marked with a red star, takes shape from a flash of lightning, and when Wonder Woman is done with them, the swords disappear, supposedly, back into her bracelets. As such, she has produced other weapons from the bracelets in this way such as a bow that fires explosive arrows, spears and energy bolts among others.
During his greeting speech, Lex made a reference to how Zeus cruelly punished the Titan Prometheus for enlightening humankind, much to the visible dismay of Diana. Shortly thereafter, she covertly stole a hacking device of Bruce Wayne's, who is likewise investigating Lex Luthor. She exited the party with Bruce pursuing her, but manages to make it to her car and drive off just in time for Bruce to see her depart.
Hidden behind this controversy is one reason for all those chains and ropes, which has to do with the history of the fight for women’s rights. Because Marston kept his true relationship with Olive Byrne a secret, he kept his family’s ties to Margaret Sanger a secret, too. Marston, Byrne and Holloway, and even Harry G. Peter, the artist who drew Wonder Woman, had all been powerfully influenced by the suffrage, feminism and birth control movements. And each of those movements had used chains as a centerpiece of its iconography.
Later, as a healer tended to Diana's battle wounds, she noted with confusion that Diana's wounds had healed completely. Diana then visited Trevor in his cell, asking him about the outside world. Due to his words, Diana decided to sneak him off the island and confront Ares herself. She snuck into the island's tower and stole the god killer, along with an Amazon shield, the Lasso of Hestia, and a special set of battle armor. She broke Trevor out of his cell and took him to the island's dock, where she was intercepted by her mother. To her surprise, Hippolyta allowed Diana to leave, gifting her Antiope's tiara. She then warned Diana to be careful, mournfully telling her that the world of men did not deserve her.
