Diana is a very kind, loving, compassionate, and strong-willed person, who, while initially somewhat naive, has become all the wiser through her time in Man's World. An outspoken egalitarian, she fights for what she believes in and generally for the betterment of mankind through love and mutual understanding, as taught to her by her mother and fellow Amazons. Growing up, Diana also proved herself headstrong and determined to do what she wanted, such as training in hand-to-hand combat under her aunt Antiope's tutelage despite her mother initially forbidding it. In this way she is quite stubborn; if she believes something is the right thing to do, then she will do it - as evidenced by her attempt to leave Themyscira without her mother's permission and insistence in attending Ludendorff's gala despite Steve telling her not to. Alongside her kindness and compassion, however, Diana was also a very naive idealist when she first arrived in "Man's World", blindly believing that all men were corrupted by Ares and that the World War I Central Powers would simply abandon their sinister ways if she killed him. This blind naivety also translated to explicit indignation whenever she was treated with disrespect due to her status as a woman, such as when she was ignored by members of the War Office. Alongside this, Diana also voiced her opinions rather bluntly upon her arrival, such as when she perceived Etta Candy's job as Steve Trevor's secretary to be akin to slavery (which earns Diana Etta's admiration). Despite her outspokenness and behavior in Man's World, however, Diana remained caring and compassionate, as demonstrated by her initially rocky relationship with Charlie and willingness to step into No Man's Land to save the village of Veld.
Voiced by Keri Russell. A movie based on the storyline written by George Perez, Gods and Mortals. This movie shows Wonder Woman's origins and how she decided to operate outside of Themyscira. Long time ago, there was a war between Ares and Hippolyta, and Hippolyta had the advantage, and was about to kill Ares, but then Hera told her not to kill Ares, but the deed, done by Ares, would not go unnoticed. From there on the Amazons got their own Island, by a request from Hippolyta, where they kept Ares a prisoner. Years further, Hippolyta wished for a child, and she made a child out of clay praying for the gods to make it a child. The next morning she wakes up and sees that a little child is in front of her. She was named Diana.
As Themyscira's emissary to Man's World, Diana has made it her duty to lead by example, even if the differences between her birthplace and new home sometimes present hurdles for her to jump. She has come to represent the possibility and potential of life without war, hate or violence, and she is a beacon of hope to all who find themselves in need. She stands as an equal among the most powerful Super Heroes, with a sense of purpose to protect the world from injustice in all forms.
During the fight, Steve approaches Diana who can't hear him speak due to an explosion temporarily rupturing her eardrums. Steve, after much talking, departs and leaves Diana with his watch before boarding the plane which is taking off with the mustard gas. Ares eventually restrains Diana, imploring her to surrender and realize the futility of their fight. Diana notices the plane in the sky as she's pinned to the ground and watches in horror as it explodes with Steve sacrificing himself to save billions of lives.
Due to the reboot of the character following Crisis on Infinite Earths, numerous things no longer made sense in terms of continuity as it related to the remainder of the DC Universe. As her first overall appearance was now in continuity around the Legends miniseries, it no longer made sense that she was a founding member of the Justice League of America. This founding position was instead given retroactively to Black Canary. Later it was decided that she should be given this position back and thus both she and Black Canary were considered founding members of the Justice League. In reference to the Justice League though, although she has more than 400 combined appearances therein, she has had most of her character development in her own series.
Shortly after coming to the outside world, Diana interrupted a terrorist attack and was named "Wonder Woman" by the press. She continued to use her gifts to fight for peace and justice in Man's World. She later fought who she thought to be Ares, though in truth it was Phobos and Deimos who were disguised as their father. Fearing that she would eventually discover the truth and free Ares from his prison beneath Themyscira, the Gods of Olympus sent Phobos and Deimos to erase all memory of Themyscira from Diana's mind. The twin gods were unable to erase the memory, so instead they later implanted false memories regarding her home to deceive Diana, leading to a completely separate origin story and causing her to hallucinate new adventures. Diana was unaware that her memories had been tampered with, and believed the falsifications until her search for the truth led her to Ares himself years later.
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.
Wonder Woman's sexual and bondage themes in her earliest days were not without purpose, however. Her creator, William Moulton Marston, theorized that human relationships could be broken down into dominance, submission, inducement and compliance roles which were embedded into our psyche. Because males were, more often than not, dominant in societies, Marston believed that "Women as a sex, are many times better equipped to assume emotional leadership than are males."  Marston wanted to convey his progressive ideals, through his use of bondage imagery, that women are not only capable of leadership roles, but should be in charge of society. Although Marston had good intentions with these themes, in Wonder Woman's early appearances, the bondage elements were controversial, as they were often seen to overly fetishize women in power rather than promote such women. Noah Berlatsky criticized this imagery in Wonder Woman's earliest days noting that "the comics take sensual pleasure in women’s disempowerment."  Despite having the mixed messages of this imagery, Marston fiercely believed that women would soon rule the earth and meant to showcase his predictions through sexual themes in his stories. He was an open feminist while studying at Harvard where he once said "Girls are also human beings, a point often overlooked!" 
The British War Council quickly gathered to discuss the notebook. Their codebreakers were unable to decipher the two different languages that it was written in, but Diana quickly identified them as Ottoman and Sumerian. She read the book out loud, informing the council that Doctor Poison had created a new form of mustard gas based on hydrogen instead of sulfur, which gas masks would be useless against.
^ Greenberger p. 175: "Journalist and feminist Gloria Steinem...was tapped in 1970 to write the introduction to Wonder Woman, a hardcover collection of older stories. Steinem later went on to edit Ms. Magazine, with the first issue published in 1972, featuring the Amazon Princess on its cover. In both publications, the heroine's powerless condition during the 1970s was pilloried. A feminist backlash began to grow, demanding that Wonder Woman regain the powers and costume that put her on a par with the Man of Steel."
