A fight broke out among the heroes for possession of the box and was only ended when John Constantine took the box, being the only one capable of doing so without being corrupted. Zatanna and Constantine took the box to the temple of Hephaestus, where the three Justice Leagues had converged again. After yet another battle between heroes, the box went dormant and the Justice Leagues discovered a Kryptonite sliver in Superman’s nervous system, placed there by the Atomica, a traitor working for the Outsider, leader of the Secret Society. Then, the Outsider used the box to open a path across universes, allowing the Crime Syndicate to enter the Justice Leagues' world.
A few decades later, second-wave feminist Gloria Steinem's Ms. Magazine debuted in 1972 with an image of Wonder Woman on the cover. Historian Tim Hanley suggests that this move shifted "the focus away from female superiority to sisterhood and equality, essentially making her a mascot of the women's movement". This perception shifted over the years, as demonstrated in December 2016 when the United Nations decided to drop the title of "honorary ambassador for the empowerment of women and girls" which it had given to the comic book character Wonder Woman a few months prior, in a ceremony attended by the actors who had portrayed her (Lynda Carter and Gal Gadot). The title was eliminated in response to a petition signed by 44,000 people which argued that Wonder Woman undermines female empowerment due to her costume, described as a "shimmery, thigh-baring bodysuit with an American flag motif and knee-high boots". The petition stated that "it is alarming that the United Nations would consider using a character with an overtly sexualised image at a time when the headline news in United States and the world is the objectification of women and girls". Wonder Woman director Patty Jenkins responded to both the petition and to the U.N.'s decision by stating that she thinks "that that's sexist. I think it's sexist to say you can't have both. I have to ask myself what I would apply to any other superhero".
This superhero era led by Kanigher didn’t last long though. The character was mired in the story lines from the golden age and especially her attachment to Steve Trevor. At the same time across the DC lineup characters were being revitalized with a new focus on science fiction. The silver age at DC is often attributed to having been started by the appearance of the re-imagined Flash in Showcase #4 in 1956. This led to a number of DC characters being reinvented such as Green Lantern and Hawkman. The difference with Wonder Woman though is that the character had managed to stay continually published since the golden age and did not get a science fiction retelling in the 1950s and 1960s. This left the character somewhat stilled mired in the past and eventually it was decided that something would be done to break her free of it. When the decision was made though it was decided that she would not have a science fiction background as it would break too much from her background as an Amazon, but that she would be slightly re-imagined as a martial arts based character, more along the lines of Batman. This would allow her to keep her somewhat unique background story, while also being more contemporary and popular. A much stronger emphasis was also placed on her appearance, as her somewhat drab civilian clothes and costume from the golden era were replaced with contemporary fashions of the time. In addition she opened a fashion boutique in trendy Greenwhich Village. This has led some to describe this era of the character as the “Mod Girl Wonder Woman.” While this version of the character did not prove to be consistently popular over the course of her brief run, it did leave some lasting impact on the character once she returned to her usual appearance. Following this she sought out more ambitious careers, for instance as a translator for the United Nations, or as a NASA astronaut and eventually moved back to Army Intelligence where she eventually got promoted to major. Also this period provided the opportunity to sever her from a dependence on Steve Trevor for her stories and her stories for the first time in her publication history became much more in line with what is considered typical of the super hero medium. The introduction of the multiverse made it such that there became two Wonder Womans, the modern version on Earth 1, and the golden age version on Earth 2. For a short time her appearances in her own comic were those of Earth 2 until the contemporary Angle Man accidentally visited her and subsequently the series was returned to modern day. The stories continued much like this for the remainder of the silver age until the end of the first Wonder Woman series with the events of Crisis on Infinite Earths. To provide closure to the character which was destined for a reboot, Steve Trevor returned and following the defense of Paradise Island from Shadow Demons, the two were finally married, though in continuity this lasted less than an issue.
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.
