These are a pair of steel cuffs that are indestructible because they were created from the remains of Zeus’s Aegis shield. Wonder Woman can use her super reflexes to deflect projectiles, blades, punches, or any form of offensive attack used against her (including Darkseid’s Omega Beams). She can also use them to deflect an object back into her enemies. When Diana crosses them to protect her from impact with larger projectiles as well as damage inflicted by explosions and collisions with hard surfaces, the bracelets generate a small energy shield. In recent events, Diana has learned how to emit a devastating magic lightning attack from her bracelets do to their link with Zeus. This attack can even strike Gods and Goddesses down with a powerful strike, and this attack can even work underwater. In the golden age these were items of submission meant to control Amazons. If they were removed from an Amazon, she would launch into an uncontrollable rage, releasing her full power (this was a plot device which subdued many foes, among them the Crimson Centipede). Also during this era, if they were bound together by a man, all her powers were lost, this was only true in the Golden Age. With the launch of the new 52 the golden age bracelets are brought back. Wonder Woman removes her bracelets and go into a "berzerker rage" of power. Wonder Woman's bracelets are what protects her opponents from her intense power in the New 52.
John Byrne's run included a period in which Diana's mother Hippolyta served as Wonder Woman, having traveled back to the 1940s, while Diana ascended to Mount Olympus as the Goddess of Truth after being killed in issue #124. In addition, Wonder Woman's Amazon ally Nubia was re-introduced as Nu'Bia, scripted by a different author. Byrne posited that Hippolyta had been the Golden Age Wonder Woman. Byrne restored the series' status quo in his last issue.
That hardly ended the controversy. In February 1943, Josette Frank, an expert on children’s literature, a leader of the Child Study Association and a member of Gaines’ advisory board, sent Gaines a letter, telling him that while she’d never been a fan of Wonder Woman, she felt she now had to speak out about its “sadistic bits showing women chained, tortured, etc.” She had a point. In episode after episode, Wonder Woman is chained, bound, gagged, lassoed, tied, fettered and manacled. “Great girdle of Aphrodite!” she cries at one point. “Am I tired of being tied up!”
We've already been warned that this outcome will lead to devastating consequences, first of which is the arrival of the Omega Titans, ancient cosmic forces that can hold entire planets in the palm of their hands. The coming of these giant new enemies has been greatly hyped by DC, and the Justice League's new fight to save the world begins in this week's Justice League: No Justice.
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.
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.
