Diana's treacherous paternal half-brother, based on the Greek mythological god of war, who masquerades as a speaker for peace on the Imperial War Cabinet as part of his deceptive master plan of conquest and destruction. Describing the Sir Patrick persona of his character, Thewlis said, "Sir Patrick's entire drive through the other half of the story is to bring about the armistice. That's his whole intention no matter what's going on. He meets Diana and see in her somebody who is sympathetic to his cause, quite vehemently so."
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.
