Past

Born approximately around the turn of the century, Alastor lived in the, having witnessed the. After he killed his murder victims, he would bury their bodies on a deer hunting ground. Sometime in 1933, while burying the body of one of his victims, he was shot and killed after being mistaken for a deer by a hunter. This is why his demon form shares many characteristics with that of a deer.

When Alastor arrived in Hell, he possessed unimaginable raw power, which was never before seen in a human soul. He quickly trampled and killed powerful demons who had been in charge for centuries and then broadcasted this carnage on the radio for everyone in Hell to hear. Other denizens would begin referring to Alastor as "The Radio Demon", and he eventually grew powerful enough to rival the Overlords of Hell; it is implied that he managed to defeat or kill an Overlord (revealed in "Masquerade" to have been Husk) and subsequently took their place. While many demons recognized his power and standing, several conversely scorned him; one of the more prominent to do so was the TV demon Vox and the two began to see each other as hated rivals.
