In her debut in All Star Comics #8, Diana was a member of a tribe of women called the Amazons, native to Paradise Island – a secluded island set in the middle of a vast ocean. Captain Steve Trevor's plane crashes on the island and he is found alive but unconscious by Diana and fellow Amazon, and friend, Mala. Diana has him nursed back to health and falls in love with him. A competition is held amongst all the Amazons by Diana's mother, the Queen of the Amazons Hippolyta, in order to determine who is the most worthy of all the women; Hippolyta charges the winner with the responsibility of delivering Captain Steve Trevor back to Man's World and to fight for justice. Hippolyta forbids Diana from entering the competition, but she takes part nonetheless, wearing a mask to conceal her identity. She wins the competition and reveals herself, surprising Hippolyta, who ultimately accepts, and must give in to, Diana's wish to go to Man's World. She then is awarded a special uniform made by her mother for her new role as Wonder Woman and safely returns Steve Trevor to his home country.[85][86]

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.
“Noted Psychologist Revealed as Author of Best-Selling ‘Wonder Woman,’” read the astonishing headline. In the summer of 1942, a press release from the New York offices of All-American Comics turned up at newspapers, magazines and radio stations all over the United States. The identity of Wonder Woman’s creator had been “at first kept secret,” it said, but the time had come to make a shocking announcement: “the author of ‘Wonder Woman’ is Dr. William Moulton Marston, internationally famous psychologist.” The truth about Wonder Woman had come out at last.
In late 2013, Zack Snyder cast Gal Gadot in the role of Wonder Woman for the 2016 film, Batman v Superman: Dawn of Justice over Élodie Yung and Olga Kurylenko.[102][103][104][105] Some fans initially reacted to this choice by criticizing Gadot's appearance.[106] Snyder would later comment on his decision to cast Gadot, stating that he tested a "bunch of actresses, as you can imagine. But the thing with Gal is that she's strong, she's beautiful, and she's a kind person, which is interesting, but fierce at the same time. It's that combination of being fierce but kind at the same time that we were looking for.[107] Gadot described Diana as having "the heart of a human so she can be emotional, she's curious, she's compassionate, she loves people. And then she has the powers of a goddess. She's all for good, she fights for good."[7] She also said that Diana has "many strengths and powers, but at the end of the day she's a woman with a lot of emotional intelligence".[108] As to how her character is different from her appearance in Batman v Superman: Dawn of Justice, Gadot said "We go back 100 years to when she's more naive", further explaining, "She's this young idealist. She's pure. Very different to the experienced, super-confident, grown-up woman you've seen".[109] Gadot underwent a diet and training regimen, practiced different martial arts and gained 17 pounds of muscle for the role.[110][111] Gadot was previously offered a different role (as a villain) in Man of Steel, which she declined because she was pregnant at the time; this allowed her to later be cast as Wonder Woman in the film's follow-up.[112] Gadot signed a three-picture deal.[104] She was paid a base salary of $300,000 for the film itself.[113]
