- Bhagwan Shree Rajneesh (also called "Osho"): Like The Leader, the Bhagwan was famous for driving in a Rolls-Royce while his followers lined the side of the road to watch him go by and greet their leader on his daily drive-bys. At one point Osho held the world record for ownership of Rolls-Royces by an individual, 93 in all.
- Aum Shinrikyo: The Japanese cult responsible for the 1995 sarin gas attack in Kobe, Japan. Inductees were subject to intense sessions in order to breakdown beliefs in their former lives and signed a statement saying "I hereby entrust power of attorney and all my assets to Aum", similar to Movementarians signing over all title to the Leader. Aum was led by Shoko Ashara who propezied the world was doomed and he was the only way to a higher world.
