The White Ninjas were a Japanese ninja cult which was in existence during the 20th century. By the 1960s, the White Ninjas resided in the Tokyo area, and, under the spiritual leadership of Dr. Go, they worshipped the Furon alien race and their deity, Arkvoodle. In 1969, they prepared to launch themselves at Halley's Comet, believing that a Furon mothership was pursuing it. However, they were ultimately persuaded not to do so when they supposedly met an actual Furon, and they became a part of the Cult of Arkvoodle.
