Demonic possession is no laughing matter – but if you find yourself pitted against one of the 13 most dangerous demons in Hell, watch out!

Anton Szandor LaVey, the former High Priest of the Church of Satan, listed the most powerful of Lucifer’s minions in his notorious book, The Satanic Bible.

“Theologians have cataloged some of the names of devils in their lists of demons, but the roster which follows contains the names most effectively used in Satanic ritual,” wrote LaVey, known to his followers as The Black Pope.

In addition to what he called the “crown princes” of Hell (Satan, the fallen angel Belial and the destructive sea monster Leviathan) LaVey lists other vicious demons who also occupy the “Royal Palace of Hell.”

Here are the 13 of the worst:

ASMODEUS – The orgy-loving ancient Hebrew devil of sensuality.

ASTAROTH – Female demon worshipped by the Phoenicians as the goddess of lasciviousness.

AZAZEL – The demon who taught man to make weapons of war and introduced women to cosmetics.

BALAAM - Hebrew devil of avarice and greed.

BEHEMOTH – Devil said to take the form of a monstrous elephant.

BEEZLEBUB – Disgusting and repulsive Lord of the Flies.

BILE – Eons-old Celtic god of Hell.

CIMERIES – Demon who rides a black horse and rules Africa.

COYOTE - American Indian devil.

DAMBALLA – Evil Voodoo serpent god.

DAGON – Philistine avenging devil of the sea.

MORMO – King of the Ghouls and chief consort of Hecate, the Greek goddess of the underworld and witchcraft.

MICTIAN – Worshiped by the Aztecs as the god of Death.
