Though Kratos in Greek mythology was the god of strength, his name is probably most familiar in modern times as the main character in the popular video game series God of War. Apparently the title “God of War” refers not to the character Kratos but to the Greek god of war Ares, who plays a role in the plot.
Though the character of Kratos in the series is supposedly not derived from the god of strength Kratos of Greek mythology, there are many indications within the game and its creation to suggest that the connection is stronger than one might be led to believe.
For example, the story takes place in ancient Greece and has many of the famous Greek gods and goddesses involved. The character Kratos is a mortal who has a tenuous relationship with the gods, to put it best. But several of the characteristics of the character Kratos come from Greek myth. The designers themselves claimed that they wanted him to look as “Greek and brutal” as possible, which fits well with the imagery of Kratos of Greek mythology.
More telling, perhaps, is the fact that chains are an important theme with the character, both in weaponry and in physical use. This could be seen as tying back to Kratos of Greek mythology’s role in the story of Prometheus, at least according to the ancient poem ‘Prometheus Bound‘ by Aeschylus. In ‘Prometheus Bound’, Kratos, on behalf of Zeus, tells the blacksmith god Haphaestus to chain Prometheus to the rocks of a mountain to serve his punishment for giving fire to the mortal world of humans.
