The chief chemist associated with General Ludendorff who specializes in chemistry and poisons.[29] 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.[40] 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.[41] 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."[42] 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".[43]
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.
In one episode, a newspaper editor named Brown, desperate to discover Wonder Woman’s past, assigns a team of reporters to chase her down; she easily escapes them. Brown, gone half mad, is committed to a hospital. Wonder Woman disguises herself as a nurse and brings him a scroll. “This parchment seems to be the history of that girl you call ‘Wonder Woman’!” she tells him. “A strange, veiled woman left it with me.” Brown leaps out of bed and races back to the city desk, where he cries out, parchment in hand, “Stop the presses! I’ve got the history of Wonder Woman!” But Wonder Woman’s secret history isn’t written on parchment. Instead, it lies buried in boxes and cabinets and drawers, in thousands of documents, housed in libraries, archives and collections spread all over the United States, including the private papers of creator Marston—papers that, before I saw them, had never before been seen by anyone outside of Marston’s family.
