Qthor is a character played by Will Hines. He is an alien from the planet Lumdun, a planet made of oxygen which is located in a different star system from Earth. He inhabited a white male body (Dave Sizer) in the hopes of taking over Earth for the elements of dirt and buildings, resources that Lumdun is wasting. His usual physical form is a gaseous billow. His plan to take over the Earth seems very poorly designed, and as the conversation continues, it appears that Qthor may be an alternate personality of the human Dave Sizer.
