Holocaustal Happy Hotel with Holocaustals celebrating victory after X-Day right before taking their Victory Shower (photographed in the future using Time Control)

One of the major schisms in the Church of the SubGenius is between the Holocaustals and Ivangelicals. The Holocaustals believe that the humans will all be killed on X-Day as the prophecies by J.R. "Bob" Dobbs foretold. The Ivangelicals believe the surviving humans will be suitable slaves after X-Day.

The Holocaustals were originally led by Papa Joe Mama, but now pledge allegiance to Dr. K'Taden Legume.
