Morgan appears and reveals himself as Ares. He tells Diana that although he has subtly given humans ideas and inspirations, using Ludendorff and Maru as pawns in the process, it is ultimately their decision to resort to violence as they are inherently corrupt. When Diana attempts to kill Ares with the "Godkiller" sword, he destroys it, then reveals to Diana that she herself is the "Godkiller", as the daughter of Zeus and Hippolyta. He fails to persuade Diana to help him destroy mankind in order to restore paradise on Earth. While the two battle, Steve's team destroys Maru's laboratory. Steve hijacks and pilots the bomber carrying the poison to a safe altitude and detonates it, sacrificing himself. Ares attempts to direct Diana's rage and grief at Steve's death by convincing her to kill Maru, but the memories of her experiences with Steve cause her to realize that humans have good within them. She spares Maru and redirects Ares's lightning into him, killing him for good. Later, the team celebrates the end of the war. In the present day, Diana sends an email to Bruce Wayne thanking him for the photographic plate of her and Steve and continues to fight and give on the world's behalf, understanding that only love can truly save the world.
The Amazon Queen of Themyscira and Diana's mother.[36] After meeting the director for the role, Nielsen said, "Patty and I met in London, and we just hit it off from the get-go. We couldn't stop talking. What was supposed to be a one-hour meeting turned into a two-and-a-half-hour lunch and we just really got each other."[37] She described Jenkins's directing style for the film as "She's also the kind of director that I really flourish under. She has very strong and particular and specific ideas about what it is she wants to say. She comes from a place of strength always. And so, when you are dealing with someone like that, you feel absolutely free to be vulnerable, to be creative, and I am a big researcher." On playing the character, Nielsen said, "It was a complete and utter pleasure and I absolutely loved every second of playing her."[38] On her character being Diana's mother and Amazonian queen, Nielsen stated, "I'm queen and I'm preparing my child for a world that entails a lot of responsibility. So it was important to me to bring that into the character."[39] She read The Amazons by Adrienne Mayor to familiarize herself with women warriors and said "I used what I learned in Mayor's book as a rallying cry for how I approached Hippolyta. And then, of course, what is a leader who is elected by her peers every year and has been doing this for a thousand years? That too was interesting to think about". Nielsen went through a workout regimen for the film, saying "I did six hours a day. You know, two hours of weight training, two hours of swords training, and then two hours of horseback riding".
Diana is depicted as a masterful athlete, acrobat, fighter and strategist, trained and experienced in many ancient and modern forms of armed and unarmed combat, including exclusive Amazonian martial arts. With her godlike abilities of incalculable superhuman strength, nigh-invulnerability, speed, flight, healing factor and semi-immortality, Diana’s fighting prowess is enhanced. In some versions, her mother trained her, as Wonder Girl, for a future career as Wonder Woman. From the beginning, she is portrayed as highly skilled in using her Amazon bracelets to stop bullets and in wielding her golden lasso.[164] Batman once called her the "best melee fighter in the world".[165] The modern version of the character is known to use lethal force when she deems it necessary.[62] In the New 52 continuity, her superior combat skills are the result of her Amazon training, as well as receiving further training from Ares, the God of War, himself, since as early as her childhood.[147] The Golden Age Wonder Woman also had knowledge in psychology, as did her Amazon sisters.[166][167]
