The Dragon was once the angel Lucifer, the most beautiful of God's angels. He gained support of other angels and rebelled against God. He was expelled from Heaven and sent to Hell where he established a evil castle known as Pandemonium. The angels who had sided with him were cast out as well and became the demons. It was the Dragon who was responsible for giving Adam and Eve the original sin by tricking Eve into eating from the forbidden Tree of Life.
The Red Dragon would begin to search Earth for his replacement. He took control of Avengelyne's body and put hers in a stripper and adult film actress named Heaven Starr. He found his possible replacement in the demon Torment, but they were both defeated by Avengelyne and Passover.
During Armageddon, the Dragon was captured by the evil angel Micah and imprisoned. On the final battlefield of Megiddo, Micah killed the Dragon, thus killing all the remaining demons. However, Micah traveled to the past where he was killed by God, starting the cycle of humanity over again and the Dragon remaining alive.
