A large and highly intelligent spirit that leads the parade of dead in The Nethermurk. He appears in the episode A Big Bad Baptism where he meets Studio Ghibli and Ranger. He explains how spirits of The Nethermurk walk the tunnels as robed ghosts until they become oxygen for the living. He is a man of science, believing they are little more than gas when they pass on. While Doctor Cum vanishes before the end of the episode, Studio converts many of the other spirits to Catholicism.
Trivia[]
