The Crisis on Infinite Earths crossover of 1986 was designed and written with the purpose of streamlining most of DC's characters into one more-focused continuity and reinventing them for a new era, thus Wonder Woman and Steve Trevor were declared to come from the Earth-Two dimension, and along with all of their exploits, were erased from history, so that a new Wonder Woman character, story and timeline could take priority.
^ Greenberger p. 175: "Journalist and feminist Gloria Steinem...was tapped in 1970 to write the introduction to Wonder Woman, a hardcover collection of older stories. Steinem later went on to edit Ms. Magazine, with the first issue published in 1972, featuring the Amazon Princess on its cover. In both publications, the heroine's powerless condition during the 1970s was pilloried. A feminist backlash began to grow, demanding that Wonder Woman regain the powers and costume that put her on a par with the Man of Steel."
Upon arriving, Diana and Hermes found themselves under attack by Hades' minions. Though they fought them off, they were surprised to find that time for Zola had passed much more quickly than for them. Her pregnancy was nearly at the end of its term. When they attempted to leave with her, Hades appeared, warning that one of them must stay behind - and if Diana was unprepared to make Hera his wife as promised - she would do. However, upon Eros' pistols, he instead agreed to let them all go in exchange for them. When Diana's back was turned, he fired them at her, and she fell under love's spell to him.
With Zola's pregnancy reaching full term, she insisted on seeing her own doctor in Michigan. While there, they were all attacked by Artemis and Apollo. Unprepared, Diana and her companions were defeated, and Zola was taken to Mount Olympus to be delivered to Hera in exchange for the throne. Apparently, Hera was willing to give up her throne for the sake of revenge. However, she had expected Zeus to return as soon as his rule was threatened, which he did not. When Apollo sat on the throne, he was crowned ruler, and when he learned of Hera's deceit, he exiled her from Olympus.
In February 1941, Marston submitted a draft of his first script, explaining the “under-meaning” of Wonder Woman’s Amazonian origins in ancient Greece, where men had kept women in chains, until they broke free and escaped. “The NEW WOMEN thus freed and strengthened by supporting themselves (on Paradise Island) developed enormous physical and mental power.” His comic, he said, was meant to chronicle “a great movement now under way—the growth in the power of women.”
Wonder Woman was soon faced with a new threat. Some years ago, Diana saved a young girl, Vanessa Kapatelis, from death at the hands of Major Disaster. She continued to visit Vanessa for many years as she recovered from her injuries, and encouraged her to undergo experimental treatment involving nanites, which allowed Vanessa to walk again. Eventually, Wonder Woman's superheroics forced her to cease her visits. During Diana's absence, Vanessa's mother Julia died, and Vanessa was left alone and felt that Diana had abandoned her. She began to resent Wonder Woman and declared herself her enemy, using the nanites in her blood to create a metallic, winged suit of armor and adopting the name Silver Swan. Silver Swan murdered a family of people that Diana had recently saved, causing Wonder Woman to fight her alongside Jason. Diana managed to drown Silver Swan until she lost consciousness, causing her to revert to her human form. She left Vanessa to recover in the care of A.R.G.U.S.
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.
The Golden Age Wonder Woman had strength that was comparable to the Golden Age Superman. Wonder Woman was capable of bench pressing 15,000 pounds even before she had received her bracelets, and later hoisted a 50,000 pound boulder above her head to inspire Amazons facing the test. Even when her super strength was temporarily nullified, she still had enough mortal strength of an Amazon to break down a prison door to save Steve Trevor. In one of her earliest appearances, she is shown running easily at 60 mph (97 km/h), and later jumps from a building[clarification needed] and lands on the balls of her feet.
The Silver Age format for comic books also did not generally favour a lot of story arcs, or at least, not memorable ones. In this period though the character did undergo some consistent changes as she battled a variety of common foes including Kobra, but the changed format gave her the ability to develop more as a character. The silver age stories of Wonder Woman can be broken into a few general arcs – the depowered stories (in the mod girl phase), undergoing tests to re-enter the Justice League of America, a golden age story about her work during the Second World War, her adventures as an astronaut for NASA, the hunt for Kobra, and eventually the return of Steve Trevor and the internal politics of working at the Pentagon. The most famous story which she was involved with at this time was “For the Man Who Has Everything”, a story focused on Superman, but also involving herself and Batman. The first major story arc which she was part of was Crisis on Infinite Earths, which also ended her silver age appearances.
