Nyarlathomon is the Ultimate for of Shoggothmon, as well as a Demon Man Digimon. Nyarlathomon has both a fair form, and a hideous true form. It goes about, gathering followers for the worship of Cthulhumon, gradually replacing their free will with its hypnotic implanted suggestions, until they are mindless zombies that do only what it commands.
Nyarlathomon's fairer form is that of a suave, Egyptian pharaoh figure with black skin and many gold adornments, standing at about 5 feet 9 inches tall. Its true form, though, is that of a terrible creature with dragon wings and many tentacles sprouting from its back. It has grown to be 8 feet tall, and its skin is an unsightly bruise-blue color.
