Twin Tail

Twin Tail (ツインテール, Tsuin Tēru) is a prehistoric Kaiju from Return of Ultraman. It first appeared in episodes 5 and 6. A strange prehistoric creature first discovered as a gigantic egg lying dormant underneath a Tokyo construction site. It hatched out as an adult shortly after its predator Gudon appeared, leading to a fierce three-way battle with Gudon and Ultraman Jack. Twin Tail has made many more appearances in the Ultra Series. As you might guess, it's almost always with its arch-nemesis Gudon. The monster's bizarre design would go on to inspire many other creatures like Litomalus and Mukadendar, as well as the popular twin tail hairstyle in Japan.
