Demon

A Demon is an evil creature in the mythology of the Humans. They are generally depicted as being humanoids, often with horns.

Self-described demons

• The Destroyer was an entity from another universe who unwillingly served Morgaine. The Destroyer had a vulnerability to silver which enabled Morgaine to chain him with manacles made of it. When shot with silver bullets fired by Brigadier Lethbridge-Stewart, the Destroyer was apparently killed. (DW: Battlefield)

• The Beast (DW: The Satan Pit/The Impossible Planet) and his son Abaddon (TW: End of Days) were ancient individuals who were sealed away to protect the universe.

The Destroyer, The Beast and Abaddon all share similarities. All three fit the depiction of demons and the Destroyer said he wished to "devour" Earth. Abaddon has the alternative name of "the Destroyer".
