Frost was allegedly a scientist looking for the key to immortality. For one of his experiments, he kidnapped a young woman in order to inject her with the blood of a recently killed vampire. The girl's fiance broke into the lab and in the resulting scuffle, Frost accidentally was injected with the blood himself. The result was that Frost became a vampire but due to the unusual method of his becoming a vampire, he was endowed with a unique characteristic. Anyone he turned into a vampire would generate a doppelgänger. He could create an infinite number of doppelgängers by biting each doppelgänger, and they would all be under his mental control. Frost intended to use this ability to contend for the position of Lord of Vampires, a position that was presently owned by Dracula.
