Gutendak is an actual fully evolved demon, as opposed to the corpulent but underdeveloped Kooklain or the cowardly and amotivational Nubbin. He is known as "The Watcher" not only because of the plethora of eyes covering his body, but also because of his paranoid tendencies and his vast collection of holodiscs, laserscrolls, datastones, and betamax tapes. Gutendak wishes to witness and catalogue -everything-. Rumors persist that he was once a researcher not unlike young Ezram, but his obsession with collecting facts lead to his karmic downfall and corruption.
After escaping the Book of the Damned, Gutendak flew westward from Exfolia to explore the geological phenomena of Caldera's burning mountain. Because demonic carapaces are composed of sulphurous fire, he is completely immune to the smoldering magma of Caldera. It is a real pity Ezram is not.
