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.
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.
Pallas Athena, the goddess of wisdom and war, granted Diana great wisdom, intelligence, and military prowess. Athena's gift has enabled Diana to master over a dozen languages (including those of alien origin), multiple complex crafts, sciences and philosophies, as well as leadership, military strategy, and armed and unarmed combat. More recently, Athena bound her own eyesight to Diana's, granting her increased empathy.
As Wonder Woman returned to her apartment, Hermes brought her to Olympus, where the gods declared her the new Goddess of War. Diana asked Apollo to restore Hera's godhood, but Apollo refused. Diana returned to London, and Apollo told her that she would not be able to ignore her responsibilities as Goddess of War for long. Diana was still angry at Hermes for his betrayal and asked him to leave, with Hermes stating that, just like she forgave Hera, perhaps in the future, she would forgive him.

The chief chemist associated with General Ludendorff who specializes in chemistry and poisons. On her role, Anaya said, "Well, it was a small role in this big ensemble, but it is an important character in the story. I'm going to be a big nightmare" for Wonder Woman and Steve Trevor. Describing her character, Anaya said, "Dr. Maru loves rage and enjoys people's pain. She's creating terrible weapons, and her purpose in life is to kill as many people as possible, and provoke as much pain as possible". She researched World War I and Fritz Haber, the scientist who created mustard gas, to prepare for the role. On the character's facial scars, Anaya stated, "I went to Patty Jenkins and asked, 'What happened to her?' And she said, 'She did it on purpose.' I was like, 'What? Patty, you're going further than I ever imagined.' She said, 'She wants to provoke painful suffering, so she tested her own gas on her own face. She wanted to know how deep this form of her gas would go, so she put it on her own face.' You can see half of her face is completely gone. This is the sadistic side of Dr. Maru". She also stated her character "is quite the opposite to the lead role of this movie, one of the strongest characters ever of DC comics, Wonder Woman. I can tell you that Doctor Poison is someone with a capacity to provoke so much pain." On Dr. Maru's relationship with General Ludendorff, Anaya said, "I think that they have a relationship based on loyalty. Ludendorff is a very tormented General that lacks self-confidence. That's why, in part, he takes these drugs that Dr. Poison gives him. They are from different worlds, but they complement each other".
In February 1941, Marston submitted a draft of his first script, explaining the “under-meaning” of Wonder Woman’s Amazonian origins in ancient Greece, where men had kept women in chains, until they broke free and escaped. “The NEW WOMEN thus freed and strengthened by supporting themselves (on Paradise Island) developed enormous physical and mental power.” His comic, he said, was meant to chronicle “a great movement now under way—the growth in the power of women.”
