Diana's bulletproof bracelets were formed from the remnants of Athena's legendary shield, the Aegis, to be awarded to her champion. The shield was made from the indestructible hide of the great she-goat, Amalthea, who suckled Zeus as an infant. These forearm guards have thus far proven NIGH-indestructible (the Omega Beams of Grail have proven able to shatter them), and are able to absorb the impact of incoming attacks, allowing Wonder Woman to deflect automatic weapon fire and energy blasts. Diana can slam the bracelets together to create a wave of concussive force capable of making strong beings like Superman's ears bleed. Recently, she gained the ability to channel Zeus's lightning through her bracelets as well. Zeus explained to her that this power had been contained within the bracelets since their creation, because they were once part of the Aegis, and that he had only recently unlocked it for her use. After the 2011 relaunch of the character, it was revealed that Diana was the daughter of Zeus and Hippolyta and that the bracelets are able to keep the powers she had inherited from Zeus in check. In addition, Hephaestus has modified the bracelets to allow Wonder Woman the sorcerous ability to manifest a sword of grayish metal from each bracelet. Each sword, marked with a red star, takes shape from a flash of lightning, and when Wonder Woman is done with them, the swords disappear, supposedly, back into her bracelets. As such, she has produced other weapons from the bracelets in this way such as a bow that fires explosive arrows, spears and energy bolts among others.
"Not even girls want to be girls so long as our feminine archetype lacks force, strength, and power. Not wanting to be girls, they don't want to be tender, submissive, peace-loving as good women are. Women' s strong qualities have become despised because of their weakness. The obvious remedy is to create a feminine character with all the strength of Superman plus all the allure of a good and beautiful woman."
