The New 52 version of Earth 2 was introduced in Earth 2 #1 (2012). In that issue, the Earth 2 Wonder Woman is introduced via flashback. She, along with Superman and Batman, are depicted dying in battle with forces from Apokolips five years in the past. This Wonder Woman worshiped the deities of Roman mythology as opposed to the Greek; the Roman gods perish as a result of the conflict. An earlier version of the Earth-2 Wonder Woman, prior to the Apokoliptian invasion, is seen in the comic book Batman/Superman, where she is seen riding a pegasus.
Who are the Dark Gods, and what is it they want? We don't actually see them in the issue; the only glimpse we have of them so far is on the cover. They look mighty and regal, and they certainly look dangerous. We don't yet know where exactly they come from, but the issue's advanced solicit description does confirm that they have arrived in the wake of Dark Nights: Metal, and that they are part of new secrets of the cosmos -- secrets that have just been unveiled. Already, we have seen that they are able to affect the minds of the masses, and turn them against their own kind. And this is only the start.
Later, Etta was released from hospital and Diana accompanied her to her home. She was shot by a sniper, but deflected the bullet and interrogated the attacker, who called herself Mayfly. She revealed that she had attempted to assassinate Wonder Woman in return for a bounty that had been placed on her. Shortly afterwards, Diana was attacked by five more assassins: Cat Eye, Cheshire, Abolith, Baundo and Plastique, the latter of whom revealed that she had planted the bomb at the wedding. Wonder Woman was able to defeat them all with the help of Etta, and they returned to an A.R.G.U.S. facility. There, Sasha Bordeaux informed her that another scientist, Hamilton Revere, had heard of Dr. Crawford's attempts to harvest Diana's DNA, and had apparently hypothesized that it could be used for the treatment of numerous diseases. Wonder Woman was intrigued and decided to seek out Revere of her own accord and hear out his plans. When she arrived, Revere informed her that in truth, he sought to use her DNA to create an army of super-soldiers. He had also used samples of Diana's blood to grant some of his goons super strength, who attacked her. Etta and Steve Trevor arrived to assist Wonder Woman, and together they bound the attackers in the Lasso of Truth, which once again removed the lie within their bodies. Revere was arrested, and Diana returned home with Steve and Etta.
Gaines didn’t know any of this when he met Marston in 1940 or else he would never have hired him: He was looking to avoid controversy, not to court it. Marston and Wonder Woman were pivotal to the creation of what became DC Comics. (DC was short for Detective Comics, the comic book in which Batman debuted.) In 1940, Gaines decided to counter his critics by forming an editorial advisory board and appointing Marston to serve on it, and DC decided to stamp comic books in which Superman and Batman appeared with a logo, an assurance of quality, reading, “A DC Publication.” And, since “the comics’ worst offense was their blood-curdling masculinity,” Marston said, the best way to fend off critics would be to create a female superhero.
Wonder Woman’s appearance in the early golden age of comics made her the first prominent female superheroine. The psychologist William Moulton Marston created Wonder Woman somewhat as a counter reaction to the presence of prominent male superheroes (at this time Superman, Batman and Captain America), as well as a counterbalance to the "blood curdling masculinity" that was dominant at the time, with the hopes that the character could serve as an inspiration for young children (though in certain ways it was geared more towards female readers.) Marston had been partially motivated to create this character because of the accomplishments of his own wife, who was also an accomplished academic at a time when it was difficult for women to fulfill this role. As a result, the first Wonder Woman series contained many complementary articles and features which sought to highlight the inner power of women. There were articles for instance on the different career paths that women could pursue (according to the standards of the 1940s) as well as a series of stories on famous and accomplished women, called the Wonder Women of History. Marston introduced the character in All-Star Comics #8 in 1941. She became the lead character in Sensation Comics in 1941, and got her first solo book in 1942.
