I need a first name for one of my characters! he's a 40-50 year old white werewolf man, it would say he's heroic but a little aggressive, and he lives in a little cabin in the woods and the time period is modern. (though some of my monster characters have old school names so crazy with it if you want.)
For you, I went ahead and searched for names with meanings that could be associated with a wolf, as well as names that mean fighter, and names with an anti-hero vibe. I also (as a fun historical nod) leaned more towards Scottish and Irish names, because they have a lot of ancient werewolf mythology.
