A cryptid of American origin. In the mid-1960s, there were some sightings of a great winged creature with massive reddish eyes. It is thought (outside of cryptozoology) that these might actually be misconstrued sandhill cranes or barn owls.
"An elusive creature first sighted in West Virginia, USA in the 1960s. About two meters in height, the Mothman wears no clothes and has a pair of giant wings on its back. It can fly at amazing speeds, and those who witness it catch only a fleeting glimpse. As a result, very little is known about it. The area where it has been spotted are also well known for U.F.O. sightings, fueling speculation that the Mothman itself may be an extraterrestrial."

Mothman can be encountered within Nakano Stone Site's silver-level instance and is one of the two final bosses that can appear within the Old Metro instance. He appears as an NPC with DB Saitou in the later docks act and Diaspora where he offers cryptic warnings.
"A cryptid sighted in West Virginia from the 1960s to 1980s. It has red, shining eyes and was known for the finlike appendages on the sides of its body. It`s said to walk on two feet and fly without moving its appendages. It can keenly sense blood to track its source and feed on it. Eyewitnesses say that a UFO was sighted when Mothman appeared, so some believe that it is actually an alien."
