"Captain" Bill Robertson is probably the person most responsible for the whole "Sci-fi Space Alien" label slapped on Scientology. After spreading rumors that the church had been infiltrated with spies he tried to start "The New Church of Scientology" with Church monies. he failed.
He claimed to be an "ethical OT" but did not act that way. Bill had a preference for dressing up in women's clothing and at least two of Bill's wives complained of his peculiar taste of wanting to play "lesbian" games as he used to dress up in ladies clothes and a wig and perform sexually perverted activities in front of a mirror. While those may be very odd, but maybe not damaging... he also stole another man's wife. Not the way an "ethical OT" should be acting.
He claimed to be second in command to L. Ron Hubbard and for a two month period in 1972 he indeed held a very high rank in the Sea Org. Over the next 10 years his behavior became very erratic. He became obsessed with remembering the words to a galactic marching song and felt the church had been infiltrated with spies.
Then, in 1982 he announced that hew was not just Bill Robertson, a normal earthling, but was in fact called Astar Paramejgian, one of three beings who were in reality controlling the lives of trillions of inhabitants of "Sector 9", a collection of thousands of stars and planets in this sector of the galaxy.
He formed the Galactic Patrol, the FreeZoners and Ron's Org, all squirrel groups. The problem with these groups was that they were altering (or making up) technology. Astar Paramejgian (aka Bill Robertson) ultimately developed a malignant throat cancer which led to his death.
