|First Appearance||Trapped in the Closet|
Seventy-five million years ago, Xenu ruled the Galactic Federation of Planets and fearing overpopulation, froze aliens from countless planets and released the frozen remains into Hawaiian volcanoes on Earth, killing them instantly. Their released souls are brain-washed by Xenu in his facilities on Earth and forced to watch brain-washing material, believing a false reality and then roaming Earth in confusion, grabbing on to the souls of men, causing all of mankind's problems.
(This is what Scientologists actually believe.)
