Loup-Garoux
The French term for werewolf. Unlike the werewolf legends, Loup-Garoux can turn at will. The Full Moon has no effect on them whatsoever. You cannot become a Loup-Garoux. You are either born one, or not. Silver can kill them. So can normal bullets, piercing through the heart-as is done with vampires-, and fire. They are not cursed, but blessed. They are more powerful than man, more powerful than beast. It is said that when they turn, they are not the disfigured hairy beasts society has made them out to be, but beautiful creatures. They look just like wolves, but slightly larger. They are mentioned in the book Blood and Chocolate, and also in the movie of that novel.
I sometimes wish I was born a Loup-Garoux, so I could murder my gym teacher. ^_^
