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.
Wonder Woman's signature weapon was her Lasso of Truth; consequently, much of her crime-fighting powers came from bondage, and her only exploitable weakness was, essentially, bondage. Grant Morrison and Yanick Paquette had teamed up to work on Wonder Woman: Earth One. Paquette confirmed that he and Morrison would be bringing back the bondage theme that was popular in Wonder Woman comics during the 1940s. However, he stated that Morrison was looking for a way to not only modernize it, but to use the bondage theme as a form of female empowerment. Paquette acknowledged that Wonder Woman has become more than just a beloved character, she is a symbol for feminism. "By bringing in sex and, yes, bondage, it reasserts [William Moulton Marston's core] idea that it is okay for women to have a healthy sexual appetite." Paquette elaborated more on this by pointing out the blatant double standards in comics when it comes to sex: "Could Wonder Woman really ever have a healthy and active sex life without it becoming political fodder for Fox News? And what of women and girls who want to be like her? Do we truly think they wouldn't be labeled sluts? I have my doubts."
Even alongside all of her kindness, compassion, and empathy, Diana is still also a warrior at heart, and when someone she cares about is hurt, becomes far more relentless and ruthless. When seemingly beaten by Ares (who was only growing more powerful from her violence, rage, and hatred), and after having to watch her beloved Steve Trevor die, she flew into an agonizing rage, and she assaulted and brutalized several armed German soldiers with immense speed and ferocity. She even came close to murdering Dr. Poison as vengeance for Steve's death; but after recalling Steve's great love for an undying belief in her and her beliefs, restrained herself and refocused her energies on Ares, harnessing her love for Trevor to overcome her violent emotions and swiftly overpower an angered Ares. Additionally, she resolved to fight even harder after Steppenwolf revealed that he had killed several other Amazons. Outside of battle, however, Diana can also react indigently and negatively towards people who disrespect her, her relatives, or those she cares about. Two such notable instances were when she shot an angry look at Lex Luthor (after he insulted her father Zeus's memory), and when she shoved back Batman (after he had insulted her beloved Steve Trevor's memory). Diana also remains ruthless when facing enemies in battle as Wonder Woman, and she even shows signs of enjoying a good battle when they put up a good fight. This was seen when she briefly smiled and laughed when she was beaten to the ground by Doomsday, and smirked as she stopped the first bullet fired at a group of hostages in London.
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.
On occasions Wonder Woman has employed a magical sword of unknown (though presumably Amazon) origin. This sword has been used most specifically against those with the power of invulnerability as invulnerability generally does not work against magical items. It is generally represented as a short sword. In Wonder Woman (vol. 4) #15, Hephaestus modifies Diana's bracelets so that she can manifest two short swords from them during battle.
