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.
Arcane Lore Expert: Wonder Woman, as both an Amazon demigoddess and an antiquities expert, possesses immense knowledge of and skill in wielding mystical artifacts and arcane lore, notably her Sword of Athena and Lasso of Hestia. Her encyclopedic knowledge was demonstrated when Wonder Woman reacted in dismay to Lex Luthor's speech (knowing how he had twisted the Olympians' history concerning Zeus and Prometheus), when she instantly identified a Parademon in Commissioner Gordon's sketch, and when she explained the history behind Steppenwolf and the 3 Mother Boxes to the remainder of the Justice League.
In London, a small group of reactionary terrorists took over the Old Bailey courthouse, taking several hostages including a school field trip. Diana storms the building, using the Lasso of Hestia to compel one of the terrorists to tell her their plans. He reveals that their leader has a bomb powerful enough to destroy several city blocks while the world media watches. Diana takes out the terrorists and neutralizes the bomb. The terrorist leader then tries to kill the hostages with a gun, but Diana protects the hostages by deflecting bullets with her bracelets.
Thus although by the modern depiction her accomplishments at the time seem ordinary, in that era they were more so. Diana Prince was originally an army nurse, but quickly attained the rank of lieutenant in Army Intelligence. This was partially a creative convenience so that she could be close to both Steve Trevor and received information which she needed to pursue her superheroics. In the real world though, this role in Army intelligence, even as the secretary to General Darnell, was still a rare position for a woman to hold in society. At this time as well, the character had her only real sidekicks in her history in the form of Etta Candy and the Holliday Girls. These characters gave the Wonder Woman a degree more of levity while also allowing the writers to focus on some issues which were more related to women. When Marston left the character, the strong driving force of the character to act as a strong moral guide and role model for female readers left as well and the character became more sensitive to the forces driving the industry as whole. Thus Wonder Woman changed somewhat to a more stereotypical woman. Her main interest was not always fighting crime, but for a time it became all in the interest of keeping Steve Trevor happy and interested in her for marriage. Also the backup stories featuring the Wonder Women of History were slowly phased out and replaced with features on marriage customs from around the world and trivial facts on random household objects.
The Golden, Silver, and Bronze Age portrayals of Wonder Woman showed her using a silent and invisible plane that could be controlled by mental command and fly at speeds up to 3,000 mph (4,800 km/h). Its appearance has varied over time; originally it had a propeller, while later it was drawn as a jet aircraft resembling a stealth aircraft.
