I have never once seen anything mentioned in the bible about such, but I have done research in the past. When I was young before I was a christian I was big into scary movies, especially werewolves. I found out though through research they were often tied to cults and associated of course with evil. I no longer watch scary movies and haven't in ages. Some though have associated werewolves with demons, and to be honest some of the stuff Hollywood comes up with you know without a doubt, has some strange influences behind it. I don't believe in werewolves, saying that, I don't fear the enemy, because I know who is greater, and greater is He that lives in me, then he that is in the world
I can't help but laugh though how media at times tries to make evil look good, or evil seem good, but evil is evil, there is no disguising it.
