Ares (also sometimes Mars) is a fictional supervillain appearing in DC Comics publications and related media. Based on the Greek mythological figure of the same name, he is the Greek god of war and the archenemy of the superhero Wonder Woman. Ares first appeared in Wonder Woman #1, published in the summer of 1942, written and created by Wonder Woman creator William Moulton Marston. In the next issue, he reappeared under his Roman name, Mars. He retained this name until February 1987, when comics writer/artist George Pérez restored the Greek name Ares as part of his reboot of the Wonder Woman mythos.
