Demogorgon (Dungeons & Dragons) - Physical Description

Physical Description

Demogorgon appears as an 18-foot-tall (5.5 m), reptilian (or amphibious) hermaphroditic tanar'ri with a somewhat humanoid form. Two mandrill heads sprout from his twin snake-like necks, and his arms end in long tentacles. His two heads have individual minds, called Aameul (the left head) and Hethradiah (the right head). One of Demogorgon's best-kept secrets, even from his cultists and minions, is that his two personas strive to dominate (and even kill) each other, but are unable to because they are aspects of one another. Despite this duality, many of Demogorgon's plots revolve around either permanently separating or uniting these two personas. According to kopru legends, Demogorgon has two mothers, which account for his twin personas. His blue-green skin is plated with snake-like scales, his body and legs are those of a giant lizard, and his thick tail is forked. His appearance testifies to his command of cold-blooded things such as serpents, reptiles, and octopi.

In the 3E sourcebook Book of Vile Darkness, he is erroneously described and depicted as having hyena heads instead of mandrill heads.

Demogorgon can charm enemies or drive enemies insane with his gaze, depending on which head's eyes are met; if both heads lock their gazes on a single target simultaneously, Demogorgon can hypnotize foes. His whip-like tail has the ability to drain the life energy right out of a living foe. His tentacles cause living creatures to rot away, as if by some sort of rapid leprosy. Because each head is a separate personality that each controls his body, Demogorgon may act twice as often during combat as he should be able to.
