This story allegedly reports the tragedy of a man who was kidnapped and taken to an unknown laboratory, where his DNA was merged with that of a bat. This caused him to have one wing (Possibly on his back, or in place of an arm) and grow black fur all over his body. This resulted in him resembling a huge bat with one wing. In his attempts to escape and return home, he was lost in the woods. Apparently sometime during his wandering, a hunter mistakenly shot, butchered, and ate him. Thinking he was some kind of animal. The next morning he was able to see the remains more clearly in the light and was horrified. He began to get sick and fell to the ground. The hunter tried to contact emergency services, but died before they arrived.
This legend is of an unknown origin and almost definitely isn't true.
