The Familiar of Red Nova, also known as the Familiar of Scar-Red Nova or the Familiar of the Crimson Devil in the Japanese version, is a fire demon whose role is to be the servant of the Red Nova. This demon planned to revive the Crimson Devil from his 10,000 year slumber, after its defeat at the hands of the Crimson Dragon, by offering Jack Atlas as a sacrifice to become the new avatar of the Crimson Devil.
