Marston introduced the idea to Gaines. Given the go-ahead, Marston developed Wonder Woman, whom he believed to be a model of that era's unconventional, liberated woman. Marston also drew inspiration from the bracelets worn by Olive Byrne, who lived with the couple in a polyamorous relationship. Wonder Woman debuted in All Star Comics #8 (cover date Dec/Jan 1941/1942, released in October 1941), scripted by Marston.
Diana sees Sir Patrick Morgan in the base, who reveals himself to be the true Ares, and tells her of his plan for a world without humanity by having them destroy each other. Ares proposes that Diana help him accomplish his vision of paradise, but Diana promptly refuses, not wanting to kill billions of innocents. Ares then reluctantly engages her in an epic battle while Steve and his comrades attempt to dismantle the plane harboring the mustard gas.
