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.
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.
