After taking out Superwoman, he calls the JLA, and alongside the JLA travels to the moon, to get to the Crime Syndicate's headquarters. From there on, every JLA'er fights against their counterparts, and Wonder Woman manages to even win against her counterpart, Superwoman.
During Marston's run, Diana Prince was the name of an army nurse whom Wonder Woman met. The nurse wanted to meet with her fiancé, who was transferred to South America, but was unable to arrange for money to do so. As Wonder Woman needed a secret identity to look after Steve (who was admitted to the same army hospital in which Diana Prince worked), and because both of them looked alike, Wonder Woman gave the nurse money to go to her fiancé in exchange for the nurse's credentials and took Diana Prince as her alias. She started to work as an army nurse and later as an Air Force secretary.

While Superman watched out for Zod, Diana visited the deserted Themyscira to speak to her mother, still a clay statue. In her absence, a demon from Tartarus had escaped from its prison and roamed free on the island. Wonder Woman destroyed the creature and sealed the gates to Tartarus with her lasso. Leaving the island, she received word from Batman that Superman was engaging Zod and Faora in battle. Reaching Superman’s side, Wonder Woman steadily overwhelmed Faora until Zod threatened Superman’s life. Wonder Woman was forced to let the criminals go.
The storyline "The Circle" was focused on the revelation of a failed assassination attempt on Diana when she was a baby, by four rogue Amazons. These Amazons – Myrto, Charis, Philomela and Alkyone, collectively referred to as The Circle – were Hippolyta's personal guards and were extremely loyal and devoted to her. However, when Hippolyta decided to raise a daughter, The Circle was horrified and considered the baby ill-fate, one who would ruin their entire race. Thus, after Diana was sculpted out of clay and brought to life, The Circle decided to assassinate the baby. Their attempt was foiled however, and the four Amazons were imprisoned. After years, the Circle escaped their prisons with the help of Captain Nazi, and decided to accomplish their previously failed mission and kill Diana. Diana defeated Myrto, Charis, Philomela and then approached Alkyone, who runs off and succumbs to her death by falling into the ocean. The other three Amazons return to their prisons.
In an October 25, 1940, interview with the Family Circle magazine, William Moulton Marston discussed the unfulfilled potential of the comic book medium. This article caught the attention of comics publisher Max Gaines, who hired Marston as an educational consultant for National Periodicals and All-American Publications, two of the companies that would merge to form DC Comics. At that time, Marston wanted to create his own new superhero; Marston's wife and fellow psychologist Elizabeth suggested to him that it should be a woman:
“As to the ‘advanced femininity,’ what are the activities in comic books which women ‘indulge in on an equal footing with men’? They do not work. They are not homemakers. They do not bring up a family. Mother-love is entirely absent. Even when Wonder Woman adopts a girl there are Lesbian overtones,” he said. At the Senate hearings, Bender testified, too. If anything in American popular culture was bad for girls, she said, it wasn’t Wonder Woman; it was Walt Disney. “The mothers are always killed or sent to the insane asylums in Walt Disney movies,” she said. This argument fell on deaf ears.
