At the time of her debut, Wonder Woman sported a red top with a golden eagle emblem, a white belt, blue star-spangled culottes, and red and golden go-go boots. She originally wore a skirt; however according to Elizabeth Martson, "It was too hard to draw and would have been over her head most of the time." This outfit was entirely based on the American flag, because Wonder Woman was purely an American icon as she debuted during World War II. Later in 1942, Wonder Woman's outfit received a slight change – the culottes were converted entirely into skin-tight shorts and she wore sandals. While earlier most of her back was exposed, during the imposition of the Comics Code Authority in the mid-1950s, Wonder Woman's outfit was rectified to make her back substantially covered, in order to comply with the Authority's rule of minimum exposure. During Mike Sekowsky's run in the late 1960s, Diana surrendered her powers and started using her own skills to fight crime. She wore a series of jumpsuits as her attire; the most popular of these was a white one.
Originally signed for three feature films, with Wonder Woman and Justice League being her second and third films, Gadot signed an extension to her contract for additional films. Jenkins initially signed for only one film, but in an interview with Variety, Geoff Johns revealed that he and Jenkins were writing the treatment for a Wonder Woman sequel and that he has a "cool idea for the second one". At the 2017 San Diego Comic Con, Warner Bros. officially announced a sequel would be released on December 13, 2019, and would be titled Wonder Woman 2; the date was later moved up to November 1, 2019, to avoid competition with Star Wars: The Rise of Skywalker. Later, Jenkins was officially signed to return as director, with confirmation that Gadot will be returning as the titular role. Days later, the studio hired Dave Callaham to co-write the film's script with Jenkins and Johns. On March 9, 2018, Kristen Wiig was confirmed to play Cheetah, the villain of the film. Later that month, it was announced that Pedro Pascal would have a key role in the film. In May 2018, long-time DCEU producer Zack Snyder confirmed on social media platform Vero that he, along with wife Deborah Snyder, will serve as producers on the Wonder Woman sequel. In June 2018, the title of the film was announced to be Wonder Woman 1984. A third film was announced in January 2019 to be taking place in the present.
Wonder Woman's character was created during World War II; the character in the story was initially depicted fighting Axis military forces as well as an assortment of colorful supervillains, although over time her stories came to place greater emphasis on characters, deities, and monsters from Greek mythology. Many stories depicted Wonder Woman rescuing herself from bondage, which defeated the "damsels in distress" trope that was common in comics during the 1940s. In the decades since her debut, Wonder Woman has gained a cast of enemies bent on eliminating the Amazon, including classic villains such as Ares, Cheetah, Doctor Poison, Circe, Doctor Psycho, and Giganta, along with more recent adversaries such as Veronica Cale and the First Born. Wonder Woman has also regularly appeared in comic books featuring the superhero teams Justice Society (from 1941) and Justice League (from 1960).
In an October 25, 1940, interview with the Family Circle magazine, William Moulton Marston discussed the unfulfilled potential of the comic book medium. This article caught the attention of comics publisher Max Gaines, who hired Marston as an educational consultant for National Periodicals and All-American Publications, two of the companies that would merge to form DC Comics. At that time, Marston wanted to create his own new superhero; Marston's wife and fellow psychologist Elizabeth suggested to him that it should be a woman:
Bracelets of Submission: Like all Amazons, Wonder Woman wears two nigh-indestructible gauntlets as part of her armor. They are incredibly durable, capable of deflecting even Ares' massive bolts of lightning and Doomsday's tremendously powerful and destructive thermal attack. Due to her powers as a demigoddess, she also has the ability to create a massive wave of energy outwards when she clashes them together.
A few decades later, second-wave feminist Gloria Steinem's Ms. Magazine debuted in 1972 with an image of Wonder Woman on the cover. Historian Tim Hanley suggests that this move shifted "the focus away from female superiority to sisterhood and equality, essentially making her a mascot of the women's movement". This perception shifted over the years, as demonstrated in December 2016 when the United Nations decided to drop the title of "honorary ambassador for the empowerment of women and girls" which it had given to the comic book character Wonder Woman a few months prior, in a ceremony attended by the actors who had portrayed her (Lynda Carter and Gal Gadot). The title was eliminated in response to a petition signed by 44,000 people which argued that Wonder Woman undermines female empowerment due to her costume, described as a "shimmery, thigh-baring bodysuit with an American flag motif and knee-high boots". The petition stated that "it is alarming that the United Nations would consider using a character with an overtly sexualised image at a time when the headline news in United States and the world is the objectification of women and girls". Wonder Woman director Patty Jenkins responded to both the petition and to the U.N.'s decision by stating that she thinks "that that's sexist. I think it's sexist to say you can't have both. I have to ask myself what I would apply to any other superhero".
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.
