The Greek messenger god, Hermes, entrusts Wonder Woman with the protection of Zola, a young woman, who is pregnant with Zeus's child, from Hera, seething with jealousy and determined to kill the child. With the appearance of a bizarre, new, chalk-white enemy, the goddess Strife (a reimagined version of Eris, the goddess of discord who had battled Wonder Woman in post-Crisis continuity), Wonder Woman discovers she, herself, is the natural-born daughter of Hippolyta and Zeus, who, after a violent clash, became lovers. Hippolyta revealed Diana's earlier origin story to be a lie, spread amongst the Amazons to protect Diana from the wrath of Hera, who is known for hunting and killing several illegitimate offspring of Zeus.
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.
Upon becoming a super-heroine, Wonder Woman became a founding member of the Justice League. Her ambassadorial duties required her to visit Washington D.C., with army officer Steve Trevor as her liaison. When Parademons stormed Metropolis, Wonder Woman resolved to defend the city, meeting the heroes Superman, Batman, Flash, Green Lantern and Aquaman. They also met the young hero Cyborg, who attempted to warn them against the evil alien conqueror Darkseid. Unfortunately, Cyborg's warnings were meaningless, as Darkseid had already arrived. Although Darkseid had initially beat them without effort, Green Lantern rallied them in order to confront Darkseid as a team. Wonder Woman proved crucial in Darkseid's defeat, stabbing him in one of his eyes to prevent him from using his Omega Beams. This gave Superman and Cyborg enough time to throw Darkseid back into his home-world.
The merger of the Greek and Roman pantheons did not sit well with the Roman goddess Diana. She accepted an offer of power from the old "Shattered God," separated from Artemis and betrayed the Olympians. Diana died in battle with Wonder Woman when she was crushed by a statue of Zeus. The Olympians were incapacitated, but Wonder Woman eventually found a way to awaken them in time for them to strike decisively at the Shattered God.
During the 25 bi-monthly issues of the "new" Wonder Woman, the writing team changed four times. Consequently, the stories display abrupt shifts in setting, theme, and tone. The revised series attracted writers not normally associated with comic books, most notably science fiction author Samuel R. Delany, who wrote Wonder Woman #202–203 (October and December 1972).
Carolyn Cocca has stated that Wonder Woman possesses a "duality of character" due to the character possessing both feminine and masculine qualities in her physical abilities and attitude, which Cocca felt made her more appealing to a wide audience. Wonder Woman's first female editor, Karen Berger, claimed that, "Wonder Woman [is] a great role model to young women, but also contains many elements that appeal to males as well. Wonder Woman crosses the gender line.". Berger worked with George Pérez on the new issues of Wonder Woman starting in 1987, and the new Diana "works with friends and allies to teach lessons of peace and equality."
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.
