Young Kratos

Throughout the Greek era of the series, Kratos is portrayed as a Spartan warrior who becomes known as the "Ghost of Sparta" after Ares, his former mentor, tricks him into murdering his family. Kratos later avenges their deaths, kills Ares, and becomes the new God of War. Kratos is eventually revealed to be a demigod and the son of Zeus, who later betrays him. Kratos embarks on several adventures in attempts to avert disaster or to change his fate, and is generally portrayed as a tragic figure. Vengeance is a central theme of the Greek era; installments focus on Kratos's origins, and his relationships with his family and the Olympian gods.
