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.
He flies out of the Kryptonian ship and lands in Heroes Park where Aquaman, Cyborg, Flash and Wonder Woman meet him. They notice that something is wrong with him, to which Clark uses his x-ray vision to scan the League before Cyborg accidentally launches a missile at him as his cybernetic body registers him as a threat. Superman attacks Cyborg with his heat vision as the rest of the Justice League try to subdue him, but he swiftly overpowers them.

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.
