Shortly after, Diana decides to venture to the Underworld to look for Zola. Lennox requests to come, but Diana shoots down his attempt, saying that she is going solo, save for Hermes as the only way to go to Hades is to either die or be escorted by Hermes. While in the Underworld, Hermes tells that the place is more or less an extension of Hades' (now preferring to call himself "Hell") will.
Coming to America for the first time, Wonder Woman comes upon a wailing army nurse. Inquiring about her state, she finds that the nurse wanted to leave for South America with her fiancé but was unable due to shortage of money. As both of them looked identical and Wonder Woman needed a job and a valid identity to look after Steve (who was admitted in the same army hospital), she gives her the money she had earned earlier to help her go to her fiancé in exchange for her credentials. The nurse reveals her name as Diana Prince, and thus, Wonder Woman's secret identity was created, and she began working as a nurse in the army.
In 1911, when Marston was a freshman at Harvard, the British suffragist Emmeline Pankhurst, who’d chained herself to the gates outside 10 Downing Street, came to speak on campus. When Sanger faced charges of obscenity for explaining birth control in a magazine she founded called the Woman Rebel, a petition sent to President Woodrow Wilson on her behalf read, “While men stand proudly and face the sun, boasting that they have quenched the wickedness of slavery, what chains of slavery are, have been or ever could be so intimate a horror as the shackles on every limb—on every thought—on the very soul of an unwilling pregnant woman?” American suffragists threatened to chain themselves to the gates outside the White House. In 1916, in Chicago, women representing the states where women had still not gained the right to vote marched in chains.
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".
Magic (Formerly): When she was a child, Diana was marked by the goddess Hecate and bestowed with a fraction of her magical ability. This power lay dormant until it was activated by the Upside-Down Man. Zatanna remarked that Wonder Woman's magical power was unlike anything she had ever seen or felt, and Diana possessed at least enough power to cast out the Upside-Down Man, an immensely powerful demon, from the world. After the Justice League Dark defeated Hecate, the Witchmarked's power was taken from them and absorbed by Circe.
Hybrid Physiology: Due to her Amazonian and Old God heritage, Wonder Woman possesses the superhuman abilities typical of these two species, such as superhuman strength, durability, speed, reflexes, agility and stamina, as well as an accelerated regenerative healing factor and the ability to live for thousands of years without visibly aging. In addition, she possesses incredible supernatural powers that allow her to generate and manipulate divine energy in the form of powerful shock waves, as well as possess some mastery over divine electricity. Wonder Woman's amazing abilities far surpass those of any other Amazon, and they are enough to rival the power of an Ancient God, such as Ares or a New God, such as Steppenwolf. Therefore, Wonder Woman is the second most powerful member of the Justice League, second only to Superman.
Genius-Level Intellect: Wonder Woman is extremely intelligent, wise, well-read, perceptive, and sophisticated, primarily due to her tremendously long immortal lifespan, natural fluency in all human languages (even dead ones, like Latin, Ancient Greek, Sumerian, and Ottoman Turkish), her having read many books even while still on Themyscira, and her century of living in "Man's World" after World War I, all of which makes Wonder Woman the wisest and most emotionally intelligent member of the Justice League, despite her having initially been naive, headstrong, and idealistic at the time of leaving Themyscira with Steve Trevor. As such, Wonder Woman has no issues blending in with the high-class society of "Man's World." She held her own while verbally sparring with Batman (with the extremely experienced vigilante having trouble discerning her identity), was the first to realize that Doomsday's adaptive healing factor was energy-based, and was the only one on supergenius Lex Luthor's metahuman list to figure out that Lex was keeping tabs on her and had obtained a compromising photo of her with Steve Trevor (possibly due to her having been once been fooled by another deceitful supervillain, Ares). She also displays a keen understanding of technology and biomechatronics, shown when Wonder Woman uses the Batcomputer, remarks on Cyborg's Mother Box enhancements, and when she deduced that resurrecting Superman with a Mother Box might produce a monster like Doomsday. Wonder Woman's intellectual genius extends itself to her combat, perceptiveness, stealth, arcane lore, and antiquities dealing skills.
Alfred informs Bruce that people are in danger, which Batman tells Flash that he needs to save the civilians. Diana and Arthur try to keep Steppenwolf away from Cyborg by using the Lasso of Hestia to pull him down, then Steppenwolf attacked them both before he knocks Arthur into a wall breaking the ceiling before Diana saves him. Cyborg tries to keep Steppenwolf away from him, but fails which leads with Steppenwolf pulling off one of his legs.
Additionally, Mayling Ng, Florence Kasumba, Madeleine Vall Beijner, Hayley Jane Warnes and Ann Wolfe portray Orana, Acantha, Egeria, Aella and Artemis, respectively, all of whom are Amazons. James Cosmo appears as Douglas Haig, Steffan Rhodri appears as Darnell, and Dutch supermodel Doutzen Kroes portrays the Amazon Venelia. Samantha Jo was cast as the Amazonian Euboea, and previously played the Kryptonian, Car-Vex, in Man of Steel. Zack Snyder also makes a brief cameo appearance in the film as an unnamed soldier.
“I have the good Sergeant’s letter in which he expresses his enthusiasm over chains for women—so what?” As a practicing clinical psychologist, he said, he was unimpressed. “Some day I’ll make you a list of all the items about women that different people have been known to get passionate over—women’s hair, boots, belts, silk worn by women, gloves, stockings, garters, panties, bare backs,” he promised. “You can’t have a real woman character in any form of fiction without touching off a great many readers’ erotic fancies. Which is swell, I say.”
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.
