Kratos (Greek mythology) is a god of strength and might, who appears briefly in Greek mythology long enough to make an impression.
Kratos is the brother of Nike (Greek goddess of victory), Bia (Greek goddess of force), and Zelus (Greek god of rivalry). The four of them together were the first to stand with Zeus (Greek mythology) as he defended Mount Olympus from the god of monsters Typhon.
This is a small, but critical role in Greek mythology, as the story of Typhon is a central myth of the Olympian gods. Kratos doesn’t play an enormous role in Greek myth, but his influence in modern mythology appears to be strong.
