The Mothan is my own adaptation of the Moth Man that I created for the world of Gravity Falls. My own fan creation.

My bio for the Mothan is this:

A mysterious, rather aggressive and somewhat vampiric beast that roams the woods at night around the town of Gravity Falls. It rarely comes into the city as it likes more secluded areas. Where the beast came is still a mystery. It preys on woodland animals but will attack a human if it stumbles across one. It possesses a incredible strength. Extreme caution is advised when ecounterimg the Mothan. Rumors in Gravity Falls state that there are perhaps others of it's kind that are more peaceful. Perhaps something is wrong with this Mothan in particular...
