Rumored as one of the Seven Devils that plagued the planet Thanagar, Ominar Synn used the properties of Nth metal to enslave the world's population, killing thousands and transforming them into an undead army.

He would have succeeded in conquering countless worlds if not for the Justice Society and Thanagar's champion Hawkman.

Believed to have been destroyed when he attempted to consume the souls of Hawkgirl and Hawkman, souls that have been bonded for millennium, evidently proved too powerful for the Sin Eater.
