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.
Ares told Diana that he had been imprisoned by the other Gods of Olympus and bound in chains that were secured by Aphrodite through the power of her love. He also told her that years ago, Phobos and Deimos had implanted false memories of Themyscira into her mind, and these had caused her to imagine aspects of her past that had never happened in reality. Meanwhile, Phobos and Deimos entered Themyscira and battled with the Amazons. Diana knew what she had to do, and called Ares to unite her with Phobos and Deimos. He teleported them to her, and using her Lasso of Truth, Wonder Woman bound them through the power of her unconditional love for them, as Aphrodite had done to Ares. With the twin gods defeated, Diana attempted to leave Ares' prison along with Veronica and Izzy, however Izzy's essence had been attached to the realm and could not return to Earth. Izzy was forced to either live out the rest of her days in the prison or live in Themyscira as an Amazon for eternity. She chose the latter and Veronica said goodbye to her daughter. Diana was briefly reunited with her mother, for the first time since she left the island.
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 engaged the First Born, but he quickly gained the advantage and attempted to kill Zeke. However, War challenged the First Born to a fight while Wonder Woman recovered. Then, Wonder Woman grabbed a spear and impaled both Ares and the First Born. As he died, Ares congratulated Wonder Woman for being a great warrior. Wonder Woman spared the First Born's life and went with Hades to take Ares' body to the River Styx.
While not completely invulnerable, she is highly resistant to great amounts of concussive force and extreme temperatures and matches Superman in this regard. She is completely immune to his heat vision, virtually any damage, or even the core of the sun. However, edged weapons or projectiles applied with sufficient force are able to pierce her skin. Due to her divine origins, Diana can resist many forms of magical manipulation.
Wonder Woman (vol. 1) #179 (Nov. 1969) showed Wonder Woman giving up her powers and returning her costume and title to her mother, in order to continue staying in Man's World. The reason behind this was that all the Amazons were shifting to another dimension, but Diana was unable to accompany them as she needed to stay behind to help Steve, who had been wrongly convicted. Thus, she no longer held the title of Wonder Woman and after meeting and training under a blind martial arts mentor I-Ching, Diana resumed crime fighting as the powerless Diana Prince. She ran a mod-boutique as a business and dressed in a series of jumpsuits while fighting crime. During this period, Samuel R. Delany took over scripting duties with issue #202. Delany was initially supposed to write a six-issue story arc, which would culminate in a battle over an abortion clinic, but Delany was removed reportedly due to criticism from Gloria Steinem, who, not knowing the content of the issues Delany was writing, was upset that Wonder Woman had lost her powers and was no longer wearing her traditional costume.
At the time of her debut, Wonder Woman sported a red top with a golden eagle emblem, a white belt, blue star-spangled culottes, and red and golden go-go boots. She originally wore a skirt; however according to Elizabeth Martson, "It was too hard to draw and would have been over her head most of the time." This outfit was entirely based on the American flag, because Wonder Woman was purely an American icon as she debuted during World War II. Later in 1942, Wonder Woman's outfit received a slight change – the culottes were converted entirely into skin-tight shorts and she wore sandals. While earlier most of her back was exposed, during the imposition of the Comics Code Authority in the mid-1950s, Wonder Woman's outfit was rectified to make her back substantially covered, in order to comply with the Authority's rule of minimum exposure. During Mike Sekowsky's run in the late 1960s, Diana surrendered her powers and started using her own skills to fight crime. She wore a series of jumpsuits as her attire; the most popular of these was a white one.
Coming to America for the first time, Wonder Woman comes upon a wailing army nurse. Inquiring about her state, she finds that the nurse wanted to leave for South America with her fiancé but was unable due to shortage of money. As both of them looked identical and Wonder Woman needed a job and a valid identity to look after Steve (who was admitted in the same army hospital), she gives her the money she had earned earlier to help her go to her fiancé in exchange for her credentials. The nurse reveals her name as Diana Prince, and thus, Wonder Woman's secret identity was created, and she began working as a nurse in the army.
