The "Diana Prince" identity has been part of Wonder Woman's history since her comics debut in 1941. In the early Golden Age stories, Wonder Woman served as a military secretary during World War II, using Prince as her cover. Later occupations Wonder Woman performed as Prince included translator at the United Nations, Air Force captain and ambassador, and in the '70s TV series, Lynda Carter's Wonder Woman used Prince to serve as an agent of the Inter-Agency Defense Command. In the DC Extended Universe, Prince works as curator for the Department of Antiquities at the extremely prestigious Louvre Museum and is held in very high esteem by the curator of the Gotham City Museum of Antiquities. Her tremendously long life span, accumulation of immense amount of knowledge and exceptional perceptiveness makes Diana Prince the wisest and most emotionally-intelligent member of the Justice League.
A stand-alone #0 Issue was released in September which explored Diana's childhood and her tutelage under Ares, the God of War. The issue was narrated in the style of a typical Golden Age comic book and saw Diana in her childhood years. The main plot of the issue was Diana training under Ares as he thought of her being an extraordinary girl with immense potential. The issue ultimately concluded with Diana learning and experiencing the importance of mercy, as she hesitates and refuses to kill the Minotaur- a task given to her by Ares; however, this show of mercy makes her a failure in Ares' eyes.
Although she has traditionally paired with either Steve Trevor or no one as a main romantic lead, and Superman with either Lois Lane or Lana Lang, there has often been the hint of a romance between the two characters. This began in the 1960 in the series Superman's Girlfriend, Lois Lane which was equal parts romance and action themed. In order to drive along the romance, the theme often came up of Lois Lane believing that Superman really loved Wonder Woman (though this was mostly for the purposes of a case.) In later years the same ideas perpetuated though most in imaginary stories or alternate tellings of the future. Following Crisis on Infinite Earths the characters were briefly linked romantically in Action Comics #600 which was written by John Byrne. Subsequently the characters' interest in one another was generally portrayed as a strong friendship (this occurred under different writers, primarily Messner-Loebs and Rucka.) Following the reboot of the DC universe into the new 52 the characters once again showed a romantic interest in one another. They found common ground in the isolation which their power give them and shared a kiss in Justice League #12 in 2012. It was later on revealed by Geoff Johns that their relationship wouldn't last for long and will end badly.
The costs for television advertisements for Wonder Woman are higher in comparison to that of previous DCEU film Suicide Squad. Warner Bros. has spent over $3 million on advertisements for Wonder Woman, whereas they spent $2.6 million on advertisements for Suicide Squad. Ticket selling site Fandango reported that Wonder Woman rounded the final leg of its marketing campaign as the most anticipated blockbuster of summer 2017, according to a poll conducted by 10,000 voters, the biggest survey in company history. Separately, Fandango also found that 92% of people surveyed said that they are looking forward to seeing a film that features a standalone woman superhero, and 87% wished Hollywood would make more women-led superhero films. In May 2017, NASCAR driver Danica Patrick drove her No. 10 car with a Wonder Woman paint scheme at the Go Bowling 400 in Kansas and at the Monster Energy Open in Charlotte.
After the release of the 2017 film Wonder Woman, many bloggers noted what they felt made Wonder Woman a feminist icon in the film. Zoe Williams for The Guardian said, "Yes, she is sort of naked a lot of the time, but this isn't objectification so much as a cultural reset: having thighs, actual thighs you can kick things with, not thighs that look like arms, is a feminist act. The whole Diana myth, women safeguarding the world from male violence not with nurture but with better violence, is a feminist act. Casting Robin Wright as Wonder Woman's aunt, re-imagining the battle-axe as a battler with an axe, is a feminist act. A female German chemist trying to destroy humans (in the shape of Dr Poison, a proto-Mengele before Nazism existed) might be the most feminist act of all." Alyssa Rosenberg for The Washington Post said, "... None of these experiences crushed me, of course, but I do wonder what it might have been like if they hadn't happened.The power of Wonder Woman, and one of the things that gives Jenkins's adaptation of the character such a lift, is in the answer to that question. Diana Prince (Gal Gadot) doesn't have any idea what women and men are — or aren't — supposed to do. Even when she does encounter other people's ideas about gender roles, she doesn't automatically accept them, and she never lets anyone stop her. And the movie goes a step further and argues that it's not merely little girls all over the world who stand to gain if they can grow up free of the distorting influence of misogyny: a world like that would be liberating and wonderful for men in lots of ways, too." Emma Gray for HuffPost said, "When it comes to pop culture, we speak often about representation; the simple yet often unfulfilled idea that it matters to see someone like you fill a variety of imagined roles on screen. After awhile, these conversations almost begin to feel obvious. We know that it's good to see women and people of color and disabled people and trans people and queer people in the same numbers and variety of roles that white, cisgender, straight men have long been afforded. But what these discussions often lose is the emotional impact of finally seeing something you may have never even realized you were missing. For many women viewers, "Wonder Woman" filled a hole they didn't know they had." 
The team learns that a gala will be held at the nearby German High Command. Steve and Diana separately infiltrate the party, with Steve intending to locate the gas and destroy it, and Diana hoping to kill Ludendorff, believing that he is Ares and thus killing him will end the war. Steve stops her to avoid jeopardizing his mission, but this allows Ludendorff to unleash the gas on Veld, killing its inhabitants. Blaming Steve for intervening, Diana pursues Ludendorff to a base where the gas is being loaded into a bomber aircraft bound for London. Diana fights and kills him, but is confused and disillusioned when his death does not stop the war.
An iron-fisted general of the German Army during World War I. Huston described Ludendorff as a "pragmatist, realist, patriotic, fighting for his country", further explaining, "he lost his son on the German front lines and was just quite tortured, diabolical, stubborn and believes that what he's doing is for the betterment of mankind." On his character, Huston said, "Ludendorff is a believer that war is a natural habitat for humans." Huston stated the film as an anti-war film and "somebody like Ludendorff would probably think that the idea that love conquers all is quite a naive concept. But finally it's true and sometimes the best way to examine mankind is from another perspective." On the genre of the film, Huston said, "It's Greek mythology. It's the origin of story and sometimes we need demigods to look at us to understand what our weaknesses are. It serves the mythological world."
In the Golden Age, Wonder Woman adhered to an Amazon code of helping any in need, even misogynistic people, and never accepting a reward for saving someone; while conversely, the modern version of the character has been shown to perform lethal and fatal actions when left with no other alternative, exemplified in the killing of Maxwell Lord in order to save Superman's life.
The most recent version of the character’s origin (since the new 52) has not yet been told in totality, but certain things are known. It has been revealed how the Amazons replenish their numbers (they do so by kidnapping sailors and using them for procreation before killing them) as well as the fact of Wonder Woman’s divine lineage. Despite the fact that Zeus is her father it does not necessarily remove other facts about her origin from canon (for instance the blessings of the gods) though it remains to be seen how or if this will be incorporated into the ongoing stories. In the Zero month of the new 52 in which DC was planning to tell the origins of the character from the new 52, the story for Diana focused on the fact that she had been trained by Ares when she was a teenager though she eventually rebelled against him. It is as of yet unclear how this factors into her new origin. When Diana first came to Man’s World she encountered a group attacking the Pentagon. Because of this she befriended Barbara Minerva who was working there on ancient antiquities and Barbara helped her acclimatize to Man’s World.
