Many writers have depicted Diana in different personalities and tone; between both of her diametric extremes; that of a worldly warrior, a highly compassionate and calm ambassador, and sometimes also as a naive and innocent person, depending on the writer. What has remained constant, and is a mainstay of the character, is her nurturing humanity: her overwhelming belief in love, empathy, compassion, and having a strong conscience. This trait had been the reason for her induction into the Star Sapphires.
This version was conceived of as a prequel to the first live-action, theatrical appearance of Wonder Woman, in the 2016 film, Batman v Superman: Dawn of Justice, placing Wonder Woman in the 1910s and World War I (a decision which differs from her comic book origins as a supporter of the Allies during World War II). As for story development, Jenkins credits the stories by the character's creator William Moulton Marston in the 1940s and George Perez's seminal stories in the 1980s in which he modernized the character. In addition, it follows some aspects of DC Comics' origin changes in The New 52 reboot, where Diana is the daughter of Zeus. Jenkins cited Richard Donner's Superman as an inspiration.
Orion tells Diana that he was sent to earth to fight a threat, and surprised that the possible threat he faces is a mere child. They find out that Zola's baby is being kept with Hermes, who in turn is hiding in Demeter's realm. Going back to the hotel to regroup, they find Zola and Hera missing. Finally finding them in a bar, Diana comes face to face with War, her old master.
