The New 52 version of the character has been portrayed to be a younger, more headstrong, loving, fierce and willful person. Brian Azzarello stated in a video interview with DC Comics that they're building a very "confident", "impulsive" and "good-hearted" character in her. He referred to her trait of feeling compassion as both her strength and weakness.
The modern age of the character can be tied to the reboot of the character following Crisis on Infinite Earths. In this the character became defined by the vision of George Perez in a way which the entire concept of the character was defined by his direction. As opposed to the past where the character would get retold origins which would try to make her more contemporary, now she got one which tied her much more strongly to the stories of the ancient gods. For the first time Diana enters Man’s World not knowing how to speak English already, and is forced to master the language on her own. In this period she also became much more closely related with modern female issues, and this was usually through her circle of friends – Julia and Vanessa Kapatelis and Mindi Mayer. Such issues as the cultural need for women to be attractive and thin, suicide and the sensationalization of the media as it pertains to women were all addressed. This version of the character also reimagined Steve Trevor as a father figure for Diana as opposed to a romantic counterpart. After Perez’s run on the character, she was taken over for a time by William Messner Loebs, who recast her again in somewhat more traditional superhero stories, though in this case she still explored a different aspect of humanity. After a long space voyage, when she returned home she was forced to work at a fast food restaurant to pay her bills and made friends with a number of people in her “civilian identity.” This built up to the revelation of betrayal of her mother, and of Artemis taking over as Wonder Woman for a short time, but this was soon reversed. The following writer was John Byrne, who when he was writing Superman in the post-Crisis on Infinite Earths DC universe, had hinted at a relationship between Diana and Superman. This was explored occasionally under his run, but it is probably best known for the death of Diana, and the assumption of her duties by Hippolyta. She was soon returned to life (as she had never really died, instead having been deified). This period also introduced Cassandra Sandsmark, who would go on to become Wonder Girl at a later point. The remainder of this second series is best remembered for by the writing of Jimenez and Rucka, both of whom helped define the character. The latter during the lead-in of events to Infinite Crisis had Diana fighting Superman who was being controlled by Maxwell Lord. Battered after their battle, Diana has managed to stop Superman by using her lasso of truth on Lord, and the only option which she is given to stopping him is to kill him, and realizing this is the case, she does so. This created a controversy both within comics and in the real world, as both fans and characters alike debated the morality of this decision. In comics this also led to strained relations between her and Superman and her and Batman and with the addition of the events of Identity Crisis, helped to lead to the breakup of the Justice League of America at a crucial point right before the main events of Infinite Crisis were about to begin.
One of the events that led to Infinite Crisis was of Wonder Woman killing the villain Maxwell Lord in Wonder Woman (vol. 2) #219. Maxwell Lord was mind-controlling Superman, who as a result was near to killing Batman. Wonder Woman tried to stop Superman, Lord (who was unable to mind control her) made Superman see her as his enemy Doomsday trying to kill Lois Lane. Superman then attacked Wonder Woman, and a vicious battle ensued. Buying herself time by slicing Superman's throat with her tiara, Wonder Woman caught Lord in her Lasso of Truth and demanded to know how to stop his control over Superman. As the lasso forced the wearer to speak only the truth, Lord told her that the only way to stop him was to kill him. Left with no choice, Wonder Woman snapped Lord's neck and ended his control over Superman. Unknown to her, the entire scene was broadcast live around every channel in the world by Brother Eye. The viewers were not aware of the entire situation, and saw only Wonder Woman murdering a Justice League associate. Wonder Woman's actions put her at odds with Batman and Superman, as they saw Wonder Woman as a cold-blooded killer, despite the fact that she saved their lives.
Though Diana was able to admit honestly that she did love Hades, she escaped her bonds anyway, explaining that she could still love him and refuse his proposal. Angrily, Hades sent all of the forces of Hell to kill her, but she and her friends were rescued by Strife. Confronted by her fiancé again, Diana explained that she had not lied. Wonder Woman has the capacity to love everyone - a concept that could never be understood by one incapable of love, such as he. The realization that he was loved unconditionally disgusted Hades so much that he sent them all away. Before leaving, Hephaestus gifted Hades with a mirror, and shot him with Eros' pistols, allowing, at least, for Hades to love himself.
With the decision to relaunch the DC Universe into the new 52, this was done by the Flashpoint story arc, where the Reverse Flash has modified the past with a vastly different modern DC Universe having resulted. In this universe Diana leads a dystopian society of Amazons that have taken over England after a battle between the Amazons and the Atlanteans led by Aquaman.
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.
This superhero era led by Kanigher didn’t last long though. The character was mired in the story lines from the golden age and especially her attachment to Steve Trevor. At the same time across the DC lineup characters were being revitalized with a new focus on science fiction. The silver age at DC is often attributed to having been started by the appearance of the re-imagined Flash in Showcase #4 in 1956. This led to a number of DC characters being reinvented such as Green Lantern and Hawkman. The difference with Wonder Woman though is that the character had managed to stay continually published since the golden age and did not get a science fiction retelling in the 1950s and 1960s. This left the character somewhat stilled mired in the past and eventually it was decided that something would be done to break her free of it. When the decision was made though it was decided that she would not have a science fiction background as it would break too much from her background as an Amazon, but that she would be slightly re-imagined as a martial arts based character, more along the lines of Batman. This would allow her to keep her somewhat unique background story, while also being more contemporary and popular. A much stronger emphasis was also placed on her appearance, as her somewhat drab civilian clothes and costume from the golden era were replaced with contemporary fashions of the time. In addition she opened a fashion boutique in trendy Greenwhich Village. This has led some to describe this era of the character as the “Mod Girl Wonder Woman.” While this version of the character did not prove to be consistently popular over the course of her brief run, it did leave some lasting impact on the character once she returned to her usual appearance. Following this she sought out more ambitious careers, for instance as a translator for the United Nations, or as a NASA astronaut and eventually moved back to Army Intelligence where she eventually got promoted to major. Also this period provided the opportunity to sever her from a dependence on Steve Trevor for her stories and her stories for the first time in her publication history became much more in line with what is considered typical of the super hero medium. The introduction of the multiverse made it such that there became two Wonder Womans, the modern version on Earth 1, and the golden age version on Earth 2. For a short time her appearances in her own comic were those of Earth 2 until the contemporary Angle Man accidentally visited her and subsequently the series was returned to modern day. The stories continued much like this for the remainder of the silver age until the end of the first Wonder Woman series with the events of Crisis on Infinite Earths. To provide closure to the character which was destined for a reboot, Steve Trevor returned and following the defense of Paradise Island from Shadow Demons, the two were finally married, though in continuity this lasted less than an issue.
In her debut in All Star Comics #8, Diana was a member of a tribe of women called the Amazons, native to Paradise Island – a secluded island set in the middle of a vast ocean. Captain Steve Trevor's plane crashes on the island and he is found alive but unconscious by Diana and fellow Amazon, and friend, Mala. Diana has him nursed back to health and falls in love with him. A competition is held amongst all the Amazons by Diana's mother, the Queen of the Amazons Hippolyta, in order to determine who is the most worthy of all the women; Hippolyta charges the winner with the responsibility of delivering Captain Steve Trevor back to Man's World and to fight for justice. Hippolyta forbids Diana from entering the competition, but she takes part nonetheless, wearing a mask to conceal her identity. She wins the competition and reveals herself, surprising Hippolyta, who ultimately accepts, and must give in to, Diana's wish to go to Man's World. She then is awarded a special uniform made by her mother for her new role as Wonder Woman and safely returns Steve Trevor to his home country.
To defend himself against critics, Gaines, in 1940, hired Marston as a consultant. “‘Doc’ Marston has long been an advocate of the right type of comic magazines,” he explained. Marston held three degrees from Harvard, including a PhD in psychology. He led what he called “an experimental life.” He’d been a lawyer, a scientist and a professor. He is generally credited with inventing the lie detector test: He was obsessed with uncovering other people’s secrets. He’d been a consulting psychologist for Universal Pictures. He’d written screenplays, a novel and dozens of magazine articles. Gaines had read about Marston in an article in Family Circle magazine. In the summer of 1940, Olive Richard, a staff writer for the magazine, visited Marston at his house in Rye, New York, to ask him for his expert opinion about comics.
