I'm looking for a strong, fierce name...?

I'm looking for a male name that is strong and fierce sounding. A little info on my character is this: He is a werewolf (When he is in wolf form he is about 7 ft tall). He is Protective of where he lives and the people who live there. He can be very aggressive, demanding and ertive. He is definitely not the person that you want to get mad. He does have a short temper but he can be gentle and kind. Among his villagers he is a sort of outcast, his parents died when he was a baby and his guardian died when he was 7. He avoids being in town as much as possible. Sorry I can't think of anymore details. I'm getting quite annoyed when I go back and read my notes and see "the boy" all the time. I figured its time I give him a name :P I'm open to all suggestions! Thanks :)
