Is it Xenu or Xemu, that is the dictator of the Galactic Confederacy?

Xenu was about to be deposed from power, so he devised a plot to eliminate the excess population from his dominions. With the assistance of psychiatrists, he summoned billions of his citizens together under the pretense of income tax inspections, then paralyzed them and froze them in a mixture of alcohol and glycol to capture their souls. The kidnapped populace was loaded into spacecraft for transport to the site of extermination, the planet of Teegeeack (Earth).The appearance of these spacecraft would later be subconsciously expressed in the design of the Douglas DC-8, the only difference being: "the DC8 had fans, propellers on it and the space plane didn't". When they had reached Teegeeack/Earth, the paralyzed citizens were unloaded around the bases of volcanoes across the planet.Hydrogen bombs were then lowered into the volcanoes and detonated simultaneously
