The Mind Sweeper was an interrogation machine developed for use by the Evil Horde. Hordak captured Orko, but not even Shadow Weaver's magic could find out anything about the little wizard's origin. Therefore, Hordak decided to use some Horde science and submit Orko to the Mind Sweeper. * Phase One of the Mind Sweeper was the Brain Scan. * Phase Two was a scan of thought processes. * Phase Ten was the Mind Sweep at full power. None of the phases had any effect on Orko. Instead, the Mind Sweeper overloaded and self-destructed.
