Kratos is a warrior in the service of the Greek gods of Olympus. Flashbacks reveal his past: once a successful but bloodthirsty captain in the Spartan army, he led his men to victory after victory until he was finally bested by a barbarian king. Staring death in the face, Kratos called out to Ares, the God of War, vowing to serve him if the god would spare his men and grant him the power to crush his enemies. Ares agreed, binding the Blades of Chaos — a pair of chained blades forged deep in Tartarus — to his new servant, and the newly armed Kratos beheaded the barbarian king.
