Deimos is the central antagonist of Dungeons & Dragons: Tower of Doom - he is a powerful and evil lich who unites many monsters and humanoids in order to ruin the surrounding lands with the ultimate goal of conquering the world once his armies have destroyed all resistance.

Served by ghouls, skeletons], hellhounds, ogres, kobolds, troglodytes and gnolls, Deimos even has a right-hand in the form of the sadistic Shadow Elf but is no push over in battle with a series of spells at his disposal once confronted by the heroes at the climax of the game.

Amongst the least of Deimos abilities are teleportation, meteor shower, fireball, animating the dead, lightning bolt, a dark shield and ring of fire.
