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".
Her level of super strength (as granted to her by Demeter) is comparable to that of the Earth itself (as this is where she derives her powers). She is on the same strength level with the strongest other DC’s characters including Superman and Captain Marvel. Thus, she is capable of lifting/carrying thousands of tons with minimal effort. It is generally accepted that she is a notch below Superman. Wonder Woman was even able to take on Powergirl in a hand to hand fight while trying to free her from mind-control. Wonder Woman and Captain Marvel were an even match when they fought. On one occasion she even used her massive strength to move the Earth (though this was under duress and aided by Superman and the Martian Manhunter.) With the launch of the new 52 Wonder Woman showed a new strength level while fighting a God, she removes her bracelets and goes into a "berzerker rage" of power, which originally allegorical to a person losing control to their destructive Ego. We then find out that Wonder Woman's bracelets are what protects her opponents from her intense power. Wonder Woman had a quick match with Supergirl where we found out that they are close in strength, Wonder Woman over powered Supergirl with her bracelets still on.
One of the events that led to Infinite Crisis was of Wonder Woman killing the villain Maxwell Lord in Wonder Woman (vol. 2) #219. Maxwell Lord was mind-controlling Superman, who as a result was near to killing Batman. Wonder Woman tried to stop Superman, Lord (who was unable to mind control her) made Superman see her as his enemy Doomsday trying to kill Lois Lane. Superman then attacked Wonder Woman, and a vicious battle ensued. Buying herself time by slicing Superman's throat with her tiara, Wonder Woman caught Lord in her Lasso of Truth and demanded to know how to stop his control over Superman. As the lasso forced the wearer to speak only the truth, Lord told her that the only way to stop him was to kill him. Left with no choice, Wonder Woman snapped Lord's neck and ended his control over Superman. Unknown to her, the entire scene was broadcast live around every channel in the world by Brother Eye. The viewers were not aware of the entire situation, and saw only Wonder Woman murdering a Justice League associate. Wonder Woman's actions put her at odds with Batman and Superman, as they saw Wonder Woman as a cold-blooded killer, despite the fact that she saved their lives.
On May 31, Wonder Woman was banned in Lebanon after the Campaign to Boycott Supporters of Israel asked the Lebanese government's Ministry of Economy and Trade to block the film because its star, Gal Gadot, is Israeli. The Lebanese government did not ban Gadot's Fast & Furious films which did screen in Lebanon. On June 7, Variety reported that a Tunisian court suspended the theatrical release of Wonder Woman after a lawsuit brought by the Al-Chaab party and the Tunisian Association of Young Lawyers to have the film blocked due to Gadot's Israeli citizenship, military service, and public comments in support of the Israeli military during the 2014 war in Gaza. Jordan was reportedly also considering a ban of the film and suspended screenings pending a decision, but on June 11, it was reported that the government decided not to do so, as there was no legal precedent for it.
The events of Crisis on Infinite Earths greatly changed and altered the history of the DC Universe. Wonder Woman's history and origin were considerably revamped by the event. Wonder Woman was now an emissary and ambassador from Themyscira (the new name for Paradise Island) to Patriarch's World, charged with the mission of bringing peace to the outside world. Various deities and concepts from Greek mythology were blended and incorporated into Wonder Woman's stories and origin. Diana was formed out of clay of the shores of Themyscira by Hippolyta, who wished for a child; the clay figure was then brought to life by the Greek deities. The Gods then blessed and granted her unique powers and abilities – beauty from Aphrodite, strength from Demeter, wisdom from Athena, speed and flight from Hermes, Eyes of the Hunter and unity with beasts from Artemis and sisterhood with fire and the ability to discern the truth from Hestia. Due to the reboot, Diana's operating methods were made distinctive from Superman and Batman's with her willingness to use deadly force when she judges it necessary. In addition, her previous history and her marriage to Steve Trevor were erased. Trevor was introduced as a man much older than Diana who would later on marry Etta Candy. Instead, Perez created Julia and Vanessa Kapatelis, a Greek-American scholar and her teenage daughter whom Diana would live with when she was in Man's world and would be major supporting characters in the series for years.
