The final remaining relics Darkseid needed were being guarded by A.R.G.U.S. at their HQ, so Darkseid decided to use a Boom Tube to transport the building and all its contents to his base in the Amazon Rainforest. The Female Furies retrieved the relics and put them into place while Wonder Woman fought Darkseid. With the relics' power, Darkseid was able to open a portal to Themyscira. As it is impossible for one who has set foot on Themyscira to return after leaving, Diana was unable to follow Grail through the portal. Grail invaded and began transforming the Amazons into creatures resembling Darkseid's Parademons. As Jason had never actually set foot on Themyscira, he followed Grail and met his mother Hippolyta for the first time since his birth. While Jason and Hippolyta fought off the transformed Amazons, Wonder Woman was able to defeat Darkseid through her love for her deceased father, Zeus, and her half-siblings, calling their spirits out of Darkseid's body and destroying him from the inside. The Amazons captured Grail and imprisoned her in the prison beneath Themyscira, alongside Ares, while Darkseid re-emerged somewhere on Earth. Jason was gifted a magical spear from his mother and returned to Earth.
Due to the format of most golden age comics, the majority of story arcs at the time for all characters were the same, Wonder Woman included. More accurately that is to say that there were not story arcs at all, as issues contained two to three stories, all of which started and concluded within the issue in question. There was therefore not much continuity in Wonder Woman until she reached the silver age. The few exceptions to this were in issues which contained a common theme, such as Wonder Woman meeting some leprechauns and each of the three stories dealing with that. Alternately there were some common themes for the character at the time, one of which was dealing with enemy saboteurs. These were mostly contemporary, and thus started as either the National Socialists in Germany or the Imperial Japanese. Later these became others.
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:
In 1954, Dr. Fredric Wertham alleged that there were lesbian subtexts to Wonder Woman and claimed comics contributed to juvenile delinquency in his book Seduction of the Innocent where despite a very obvious heterosexual relationship with Steve Trevor, Wertham asserted that Wonder Woman’s association with the Holliday Girls could be interpreted as a lesbian relationship. The Comics Code Authority was then introduced in reaction to Wertham 's claims against the entire industry.
