To find the perfect location to shoot the Amazon island of Themyscira, the birthplace of Wonder Woman herself, the film's producers searched all over the world, finally settling on the Cilentan Coast: a stretch of coastline on the Tyrrhenian Sea, located in the Province of Salerno in Southern Italy. It was chosen because most beaches in the world that sit below big cliffs disappear beneath the tide for part of every day. Production designer Aline Bonetto and her location manager Charles Somers considered 47 countries and visited several of them before they found what they were looking for. Bonetto explained that, "Italy had beautiful weather, a beautiful blue-green sea, not too much tide, not too much wave. Our effects team added some cliffs in post-production, and it was the perfect way to go". The estuary at Lower Halstow in Kent is featured in the scene in which Diana arrives at a Belgian creek to make her way to the warfront. Bill Westenhofer served as the visual effects supervisor for the film and Martin Walsh served as editor.
Following Pérez, William Messner-Loebs took over as writer and Mike Deodato became the artist for the title. Messner-Loebs introduced Diana's Daxamite friend Julia in Wonder Woman vol. 2 #68 during the six-issue space arc. Messner-Loebs's most memorable contribution to the title was the introduction of the red-headed Amazon Artemis, who took over the mantle of Wonder Woman for a short time. He also included a subplot during his run in an attempt to further humanize Diana by having her work for a fictional fast food chain called "Taco Whiz".
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.
Wonder Woman was taken to Zamaron where the Star Sapphires informed her that a Dark God had taken hold there, too. Diana fought the newly-emerged Karnell, Dark God of Love, who informed Diana that he and his brethren had come from the Dark Multiverse, which the Justice League had recently encountered. When Diana wore the Tenth Metal during the climax of the Justice League's battle with Barbatos, Diana had wished for the gods' return. Though she had meant the Gods of Olympus, the Dark Multiverse's gods were chosen instead, and thus she had unintentionally caused their invasion. Together with the Star Sapphire Corps, Wonder Woman was able to defeat Karnell, who retreated back to Earth. Wonder Woman left the Corps and returned home. In her absence, Jason had united with the Justice League and fought the Dark Gods, who had plunged Earth into chaos. Suddenly, the Dark Gods disappeared, only for them to return with Jason at their side. Jason fought Wonder Woman, but after he led her away from the Dark Gods, he revealed that he was using his armor to channel the power of Dolos, God of Deception, and was in fact deceiving the Dark Gods. Using the wisdom of Athena, Jason developed a plan to convince the Dark Gods to retreat back to their reality. He offered himself, along with the power of the Greek Pantheon, in exchange for the Dark Gods leaving Earth. The Dark Gods accepted the proposal and Diana tearfully said goodbye to her brother, who was taken with them to the Dark Multiverse. The planet was saved and its people returned to normal, but Diana was distraught over the loss of her brother.
With Wonder Woman arriving in pursuit, Strife warned of the prophecy Apollo and Artemis feared: a child of Zeus would kill a god to take the throne. That child could be either Diana or Zola's child. Sending Zola back with Hermes to have her baby in peace, Diana warned that if they were not left alone, she would fulfil the prophecy herself. Unfortunately, upon her return to Michigan, Diana found that Hermes had betrayed them, and once Zola gave birth to her son, he whisked the child away, and gave it to Demeter. Diana swore to get the boy back and bring Hermes to justice.
Perhaps due to her Amazonian background, Diana greatly respects other noble selfless warriors, as evidenced when she attended Superman's funeral in Smallville and spoke of how he had been much more than a soldier (adding to what Batman said about Metropolis burying an empty casket). As a result of her great posthumous respect, she was, therefore, more than willing to aid Batman in honoring the heroic death of Superman, by helping round up the metahumans from Lex Luthor's files to form a team of superheroes (later known as the Justice League) to protect the world from the imminent mysterious alien invader Steppenwolf and his Parademon minions after Superman's death left the world vulnerable.
The Pre-Crisis version of the invisible plane was a necessity because before Crisis on Infinite Earths rewrote Wonder Woman's history – along with the histories of many other heroes – Wonder Woman could not fly. She grew increasingly powerful during and after the Silver Age of Comic Books, acquiring the power to ride wind currents and imitate flight over short distances. This had limitations, however; for example, if there was no wind and the air was completely still she would be trapped on the ground or if dropped from a distance that she would helplessly fall out of control to the ground. Though this meant that she would rely on the invisible plane less frequently, she always had need of it.
A stand-alone #0 issue was released in September which explored Diana's childhood and her tutelage under Ares, the God of War, now known most often as simply 'War'. The issue was narrated in the style of a typical Silver Age comic book and saw Diana in her childhood years. The main plot of the issue was Diana training under War 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, which she first learned when War showed it to her during their sparring. This later translated into her refusal to kill the Minotaur – a task given to her by War; however, this show of mercy makes her a failure in War's eyes, which was actually his fault since he inadvertently "taught" her mercy and affection as his protege. Later in the series, Wonder Woman is forced to kill War during a conflict with her evil half-brother, Zeus' son First Born, and herself becomes the God of War. After the Amazons are restored, she rules over them both as a warrior queen and God of War, as the ongoing conflict with First Born escalates. At the end of Azzarello's run, as part of a final conflict, Wonder Woman kills First Born, while Zeke is revealed to have been Zeus' plan for resurrection, with Zola revealed to have been a mortal shell for the goddess Athena, who gave birth to Zeus just as he once did to her. Wonder Woman pleads with Athena not to allow the Zola personality, whom she has grown to love as a friend, die with Athena's awakening. Athena leaves the site in animal form, leaving a stunned and confused Zola behind with Wonder Woman.
A Blackfoot demi-god, and a smuggler who trades with both sides of the war and knows how to get people across the front lines. On his casting, Brave Rock said, "I had no idea it was for Wonder Woman. I lost it when I showed up and I couldn't remember my lines. I didn't take it literally until a month later, I got a call saying I got the role and they wanted me to fly to London for a fitting." Brave Rock raised several concerns with Jenkins over the representation of the character in the film, particularly that he was not comfortable playing into stereotypes and that he was not keen on his character being simply known as "Chief". Jenkins responded by giving him some extra creative control over his character which Brave Rock says was "unprecedented".
With Artemis' help, Wonder Woman tracked Zola down to a subway station, where they found a lock of fox fur. Realizing that Zola was with Dionysus, they went to Providence, where Dionysus was currently located. They found Dionysus captured by Cassandra's minion, the Minotaur. When Cassandra's forces were about to depart to Olympus, Wonder Woman ambushed them and hung onto their plane. When the jet arrived to Olympus, the mountain was hit by a massive explosion.
Unfortunately, not long after Diana left, Hera came for her vengeance, and though she could not bring herself to kill Hippolyta, she could not forgive her either. Feeling regret at giving up the only real family she had, Wonder Woman returned to Themyscira to find the Amazons absent, and her mother turned to stone. Shortly after, Wonder Woman encountered Lennox, a man who claimed to be another of Zeus' bastard children. After learning that Zeus has gone missing, they confronted the Gods of Olympus, Poseidon and Hades, in order to prevent them from taking over Zeus’ throne. To prevent a war between gods, Diana proposed that the two brothers share Heaven with one ruling during the day, and the other at night. Hera angrily interceded, which was what Diana had planned, and using Hermes' staff she transported herself to Mount Olympus to face Hera alone. She warned that she would make Hera regret what she had done to her mother before returning to Earth. Unfortunately, by the time she had returned, Hades had kidnapped Zola with the warning that Diana would need to make good on her bargain or Zola and her child would die.
