The success of the superhero television series Supergirl informed the marketing and promotion strategy used for Wonder Woman. According to Time Warner chief marketing officer Kristen O'Hara, they wanted to approach the Wonder Woman marketing campaign in a light manner, similar to how they did with Supergirl. O'Hara elaborated that the modest campaign route they took for Supergirl aided in establishing a large central fanbase among women well in advance of the series, which reportedly generated 5 million female superhero fans in one week. They were then able to model over time, and grow that audience leading up to the 15-months-later release of Wonder Woman. Though neither the film nor the series are aimed exclusively at women, the latter's campaign gave them their first opportunity to begin collecting data about female superhero fans. In May 2017, a promo for Wonder Woman was released during the season finale of Supergirl, featuring a remix of the song "These Boots Are Made for Walkin'" and Supergirl (Melissa Benoist) wearing Wonder Woman's boots. The promo included an appearance by Lynda Carter, star of the 1970s Wonder Woman, who plays the American president on Supergirl.
Lasso Mastery: Wonder Woman is extremely skilled at wielding her unbreakable Lasso of Hestia both offensively and defensively, notably using it to stop an escaping German spy, to take down numerous German soldiers in World War I battles, to retrain a British terrorist leader, to restrain and defeat General Ludendorff, to hold her own against Ares after getting her sword destroyed, to restrain a resurrected Superman (albeit unsuccessfully), and to even restrain Doomsday himself.
Impressed by this unknown woman's self-sacrifice, the Amazons entombed her with honors and clothed her in armor displaying the American flag pattern on her uniform, which they assumed were her heraldic colors. Trevor's legacy was also the primary reason why Ares arranged for Steve Trevor to bomb the island, as he could not resist the irony of the heroine's son unwittingly killing her admirers.
After Diana's clash with Silver Swan, she goes to Greece, where Julia is staying. Here she meets Julia's friend, renowned Epigraphist Stavros Christadoulodou. Here, a conspiracy is shown to be in play with a mysterious woman behind it, dwelling in an undisclosed location, speaking to her servant Mikos about Diana's presence and how it could be a threat. A rebel group is revealed to be in existence, secretly fighting the witch's forces, headed by a man named Gregory, who had lost his son's to the witch's monsters. The witch uses her servants disguised as animals to kill her enemies in the rebel group. The rebel faction also has Katina and Spiros as it's members, actively tracking other followers of the witch and trying to keep Diana safe from harm. She goes on boat to an island called Cephalonia when she is distracted by another small island in the vicinity. She senses a strange presence in the island and is somehow attacked by it's mysterious resident psychically, as a warning, causing her to faint on the spot. In the hospital, Diana is surrounded by her friends and some wonder if it's the Magia, a curse that some believe is pure superstition. The Magia is said to come from the mysterious island, where a witch is said to exist. Diana is introduced to Theophilius Ventouras, one of the wealthiest people in the area by Julia, who is actually another pawn of the witch, and he deceives Diana and her friends into thinking the woman is actually a rich loner and there is no truth in the myths about the Magia and the Witch. Stavros meets with Gregory and is given a scroll that the faction had obtained from the island, which may contain secrets about the witch.
In March 2005, Warner Bros. and Silver Pictures announced that Joss Whedon would write and direct the film. Early drafts of his screenplay included Steve Trevor as the narrator, a fierce battle between Diana and her mother over Trevor's welfare, and after leaving Themyscira, his need to frequently rescue a Diana rendered helpless by the modern world. Whedon was not able to complete a final version of his screenplay, and left the project in 2007.
Ares told Diana that he had been imprisoned by the other Gods of Olympus and bound in chains that were secured by Aphrodite through the power of her love. He also told her that years ago, Phobos and Deimos had implanted false memories of Themyscira into her mind, and these had caused her to imagine aspects of her past that had never happened in reality. Meanwhile, Phobos and Deimos entered Themyscira and battled with the Amazons. Diana knew what she had to do, and called Ares to unite her with Phobos and Deimos. He teleported them to her, and using her Lasso of Truth, Wonder Woman bound them through the power of her unconditional love for them, as Aphrodite had done to Ares. With the twin gods defeated, Diana attempted to leave Ares' prison along with Veronica and Izzy, however Izzy's essence had been attached to the realm and could not return to Earth. Izzy was forced to either live out the rest of her days in the prison or live in Themyscira as an Amazon for eternity. She chose the latter and Veronica said goodbye to her daughter. Diana was briefly reunited with her mother, for the first time since she left the island.
Wonder Woman (vol. 1) #179 (Nov. 1969) showed Wonder Woman giving up her powers and returning her costume and title to her mother, in order to continue staying in Man's World. The reason behind this was that all the Amazons were shifting to another dimension, but Diana was unable to accompany them as she needed to stay behind to help Steve, who had been wrongly convicted. Thus, she no longer held the title of Wonder Woman and after meeting and training under a blind martial arts mentor I-Ching, Diana resumed crime fighting as the powerless Diana Prince. She ran a mod-boutique as a business and dressed in a series of jumpsuits while fighting crime. During this period, Samuel R. Delany took over scripting duties with issue #202. Delany was initially supposed to write a six-issue story arc, which would culminate in a battle over an abortion clinic, but Delany was removed reportedly due to criticism from Gloria Steinem, who, not knowing the content of the issues Delany was writing, was upset that Wonder Woman had lost her powers and was no longer wearing her traditional costume.
This version was conceived of as a prequel to the first live-action, theatrical appearance of Wonder Woman, in the 2016 film, Batman v Superman: Dawn of Justice, placing Wonder Woman in the 1910s and World War I (a decision which differs from her comic book origins as a supporter of the Allies during World War II). As for story development, Jenkins credits the stories by the character's creator William Moulton Marston in the 1940s and George Perez's seminal stories in the 1980s in which he modernized the character. In addition, it follows some aspects of DC Comics' origin changes in The New 52 reboot, where Diana is the daughter of Zeus. Jenkins cited Richard Donner's Superman as an inspiration.
DC Comics Executive Editor Dan DiDio asked fans for 600 postcards to restore the Wonder Woman comic book to the original numbering, starting at #600. The publisher's office had received 712 postcards by the October 31, 2009 deadline. As a result, the numbering switched to #600 after Wonder Woman #44, in an anniversary issue. Issue #600 featured several stories featuring work from guest creators such as Geoff Johns, George Pérez, Phil Jimenez, and Amanda Conner. The issue featured guest appearances from other female superheroes such as Batwoman, Power Girl, Batgirl, Stargirl and the Question.
