Years ago, Namor had an affair with a mistress of the Atlantean Court. She gave birth to their son, Kamar. Namor loved her and their son. His happiness soon ended when his love was murdered by someone that was never found. Namor sent Kamar away to protect him.

Kamar has been raised by Zoran, who filled Kamar's head with lies. He told him that Namor was ashamed of him and the fact that his mother did not have royal blood in her. He told Kamar that Namor had her killed because he did not want Kamar to grow up and become heir to the throne of Atlantis.

As revenge against his father, Kamar formed the 13th Atlantean Sleeper Cell to attack the surface world that Namor has grown to love.
