In American folklore, Mothman is the name given to a humanoid creature that was reportedly seen around Point Pleasant, West Virginia, from November 15, 1966, to December 15, 1967. Despite its name, the original sightings of the creature described avian features. The first newspaper report was published in the Point Pleasant Register, dated November 16, 1966, titled "Couples See Man-Sized Bird ... Creature ... Something". The national press soon picked up the reports and helped spread the story across the United States. The source of the legend is believed to have originated from sightings

Xenu ( ), also called Xemu, is a figure in the Church of Scientology's secret "Advanced Technology", an esoteric teaching held sacred by adherents. According to the "Technology", Xenu was the extraterrestrial ruler of a "Galactic Confederacy" who brought billions of his people to Earth (then known as "Teegeeack") in a DC-8-like spacecraft 75 million years ago, stacked them around volcanoes, and killed them with hydrogen bombs. Official Scientology scriptures hold that the thetans (immortal spirits) of these aliens adhere to humans, causing spiritual harm.
