I think it might be a panther.
There's also the Heatherly's Point panther/man. That's a place on Norris Lake that people claim to encounter a half man, half panther. It's actually in some pretty popular urban legend stories you'll read. I've spent many nights camping at Heatherly's point though and I've never seen it. I've actually stayed up alone all night there fishing while, everyone else slept and never felt the least bit uneasy.
Another local one here in East, TN is the Red Ash, Goat Man. He's half goat half man of course. Again I've never seen him but I do know that not many people......myself included will travel through Red Ash late at night. You never know what you're gonna see up there. They have devil worship ceremonies there sometimes. I don't know if that has anything to do with why there's a goat man there but, I'd feel pretty safe in saying that it's a demon and not really a man conceived of a goat and a woman or a man and a goat....yuck! That made a little too vivid of a picture pop up in my mind. LMAO......That's disgusting. Anyway......I don't think that ever happened.....who knows though, this is redneck country. I will tell you something that IS there though. I know this one because I've actually seen it only when I saw it....I had no idea. There's a train track runs through there that hasn't been used for twenty years or so. Sometimes you can hear the train. I got a little luckier than that one day. I was up in there riding around with my ex-husband. We pulled off on some little dead-end back road. Honestly.....we were probably looking for a place to smoke a J. Anyway, my husband was a real idiot. We had already smoked and we heard a train coming. He cranked the engine and flew out across the tracks in front of an oncoming train. He had to beat it. I don't know......I think he had a testosterone abnormality or something.....he always had to do all this macho stupid stuff. Anyway, we saw the train. I distinctly remember some of the cars being green. I had no idea til' actually years later that the train doesn't run out there anymore. I told a friend about how stupid he was to run out in front of that train. She just said, "Are you serious?" I said, "Yeah, he was a pure idiot!" She said, "NO, I know he was an idiot......I mean about seeing the train." I told her, "Yeah, why?" Then she told me that there was no train there anymore. I thought she probably didn't know what she was talking about til' I read about it on an urban legend site. Freaky huh?
