UnrevealedElder Demon

Little is known about this enormous and powerful demon, other than he was somehow imprisoned in a Crystal of power, which was coveted by both Galactus and Thanos. They both sent agents to collect the artifact for their own personal gain. In a brief confrontation the White Raven managed to destroy the Crystal, which freed the Elder Demon. Once freed, the demon attacked her; however, she was rescued by the Silver Surfer. The Elder Demon appeared to be on the verge of victory, until White Raven, rammed her starship into the demon causing a massive explosion, which appeared to kill the creature.
