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.
Her level of super strength (as granted to her by Demeter) is comparable to that of the Earth itself (as this is where she derives her powers). She is on the same strength level with the strongest other DC’s characters including Superman and Captain Marvel. Thus, she is capable of lifting/carrying thousands of tons with minimal effort. It is generally accepted that she is a notch below Superman. Wonder Woman was even able to take on Powergirl in a hand to hand fight while trying to free her from mind-control. Wonder Woman and Captain Marvel were an even match when they fought. On one occasion she even used her massive strength to move the Earth (though this was under duress and aided by Superman and the Martian Manhunter.) With the launch of the new 52 Wonder Woman showed a new strength level while fighting a God, she removes her bracelets and goes into a "berzerker rage" of power, which originally allegorical to a person losing control to their destructive Ego. We then find out that Wonder Woman's bracelets are what protects her opponents from her intense power. Wonder Woman had a quick match with Supergirl where we found out that they are close in strength, Wonder Woman over powered Supergirl with her bracelets still on.
Demeter, the goddess of agriculture and fertility, blessed Diana with strength drawn from the Earth spirit Gaea, making her one of the physically strongest heroes in the DC Universe and the strongest female hero in the DC Universe. This strength has allowed her to easily overwhelm Superman and Supergirl. She has also held her own against Darkseid. Her strength has no measurable limits and she can break the Chronus Scepter, which is universal in its destructive power. However, now Diana is the daughter of Zeus, king of the Greek Gods, so it is unclear as to how much of her power and strength is a direct result of her divine heritage. Her connection to the earth allows her to heal at an accelerated rate so long as she is in contact with the planet. However, as mentioned earlier, now that she is a demigoddess, it has been suggested that she heals extremely quickly also due to her divine heritage. In rare cases where she has been gravely injured, Diana showed the ability to physically merge with the earth, causing whatever injuries or poisons to be expelled from her body; such an act is considered sacred, and can only be used in extreme cases.
The First Born imprisoned Wonder Woman in what remained of Olympus and ordered his forces to attack Themyscira. As they watched the confrontation, the First Born offered her a place in his goals of conquest, but she steadfastly refused, causing him to thrust a spike into her side. As Diana lied mortally wounded, Eris dragged her to Themyscira, for she wanted Diana to see her home destroyed and humiliate her. Recovering her strength, Wonder Woman punched Eris down and took Zola and Zeke to Olympus. Her plan was to place Zeke on the throne, so that he could be the new king of Olympus and end the bloodshed, but before she could, Poseidon revealed his presence.
With the appearance of the Bana-Mighdallian Amazons, the Olympians faced a new prospect. Though devout Amazons, these newest citizens of Themyscira do not worship the Greek gods. Renouncing them millennia ago, the tribe instead worship a combination of Egyptian and middle eastern deities. The central gods worshipped by the desert Amazons are: Isis (wisdom and magic), Mammitu (judgement bringer), Bast (nature and feminine), and Neith (mother figure and protection). These gods followed the Bana-Mighdallian Amazons to Themyscira where they continued to be worshipped. Facing the situation with hands tied, both pantheons agreed to integrate themselves with each other for the benefit of their people. Though these new gods do not reside on Olympus, they are treated with diplomacy when called to aid the Amazons in a united godly role. Despite the gods mentioned being part of the inner-circle of deities in the Bana's belief system, less significant gods have been shown to be part of their godly pantheon as well such as Sekhmet (war god), Thoth (their only known male god) and possibly Ishtar (love goddess). The gods of Bana-Mighdall proved their loyalty to the Olympians by aiding the Greek gods in battle when the war gods Sekhmet and Ares previously devised a coup on Olympus.
After taking Despero to the authorities, Wonder Woman and Superman came across the mysterious Pandora, someone Wonder Woman was familiar with. She believed Superman could use her box to trap the evil she unleashed in ancient times; but when Superman touched it, he was overwhelmed by its power. While Pandora took the box and left, the two heroes received news that a new superhuman, Shazam, was entering the borders of Kahndaq. Their confrontation with Shazam turned violent until the rest of the Justice League and the Justice League of America intervened to defuse the situation. Suddenly, Dr. Light lost control of his powers and began absorbing Superman's solar energy, unleashing an energy beam at Wonder Woman. In a fit of anger, Superman killed Dr. Light with his heat vision, an action that caused a fight between the two Leagues.
Wonder Woman's sexual and bondage themes in her earliest days were not without purpose, however. Her creator, William Moulton Marston, theorized that human relationships could be broken down into dominance, submission, inducement and compliance roles which were embedded into our psyche. Because males were, more often than not, dominant in societies, Marston believed that "Women as a sex, are many times better equipped to assume emotional leadership than are males."  Marston wanted to convey his progressive ideals, through his use of bondage imagery, that women are not only capable of leadership roles, but should be in charge of society. Although Marston had good intentions with these themes, in Wonder Woman's early appearances, the bondage elements were controversial, as they were often seen to overly fetishize women in power rather than promote such women. Noah Berlatsky criticized this imagery in Wonder Woman's earliest days noting that "the comics take sensual pleasure in women’s disempowerment."  Despite having the mixed messages of this imagery, Marston fiercely believed that women would soon rule the earth and meant to showcase his predictions through sexual themes in his stories. He was an open feminist while studying at Harvard where he once said "Girls are also human beings, a point often overlooked!" 
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.
