Steve Trevor's secretary who befriends Diana. Describing her character, Davis said, "She's a woman in a man's world and so being heard and seen aren't the easiest things, but it kind of doesn't deter her", adding, "Etta is unapologetically herself and I think that that's the thing that has drawn me to her the most". When asked if she was previously familiar with the character, Davis responded, "No. I wasn't. It took me a while to know that I was auditioning for Etta because even when I found out it was Wonder Woman, I still had no idea what the role was. It took a little while then I Googled the character". On Etta Candy's relationship with Steve Trevor, Davis said, "One of the great things that Etta gets to work with Steve Trevor is because Steve is not your typical man, in that he does entrust her with things that in 1918 probably wouldn't have been entrusted to a secretary of somebody who is quite important", further explaining, "So I think that [Trevor] needs her just as much as she needs that because now she's been given responsibility that she wouldn't have normally be given before, and equally he has somebody who could probably fly under the radar a bit. So he can trust the person who no one's really looking at".
Marston introduced the idea to Gaines. Given the go-ahead, Marston developed Wonder Woman, whom he believed to be a model of that era's unconventional, liberated woman. Marston also drew inspiration from the bracelets worn by Olive Byrne, who lived with the couple in a polyamorous relationship. Wonder Woman debuted in All Star Comics #8 (cover date Dec/Jan 1941/1942, released in October 1941), scripted by Marston.
As Hippolyta was still a clay statue, Diana was forced to take the Amazon throne, at least until she could find a way to turn her mother back to normal. At the same time, the Justice League had discovered strange environmental events that had destroyed small villages around the world, leaving only vegetation behind. Furious, Wonder Woman attacked Swamp Thing, accusing him of causing such devastation, while Swamp Thing claimed innocence. Aquaman defused the situation before it could escalate any further. Later, Wonder Woman returned to Themyscira, only to discover Hippolyta's statue had crumbled. On a training session, Clark asked Diana if she wanted to talk about her recent experiences, but Diana replied that, as queen, grief is not a luxury she could afford. Later, Diana was called for a meeting by the Amazon council, which forced a choice on her: become permanent Queen or abdicate the throne. Before the discussion could continue, the island was attacked by Stymphalian Birds, Ares’ pets who were now drawn to Diana as the God of War. Accepting her new responsibilities, Diana successfully defended Themyscira.
Following the events of the Darkseid War, Wonder Woman is told by the dying Myrina Black that on the night of Diana's birth, Hippolyta gave birth to a twin child. This child was revealed to be male, known as Jason, and is said to be incredibly powerful. Wonder Woman makes it her mission to find him. At the same time, she finds the truth behind her origin and history is now cluttered, as she remembers two versions: the pre-Flashpoint one, and the New 52 rendition. She cannot locate Themiscyra or her fellow Amazons and the Lasso of Truth does not work for her anymore.
The story behind the writing and editing of Wonder Woman can be pieced together from Bender’s papers, at Brooklyn College; Frank’s papers, at the University of Minnesota; and Marston’s editorial correspondence, along with a set of original scripts, housed at the Dibner Library at the Smithsonian Institution Libraries. In his original scripts, Marston described scenes of bondage in careful, intimate detail with utmost precision. For a story about Mars, the God of War, Marston gave Peter elaborate instructions for the panel in which Wonder Woman is taken prisoner:
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.
