WELL. Clearly Eddy and Atticus are both delighted to meet him. And of course so is Drei. Considering he has a vested interest in a certain other HP werewolf.
As far as my non-HP people, Ben would very much not be a fan of him because YOU ARE WHAT GIVES WEREWOLVES A BAD NAME, Lorne. His reputation is very important to him. Clark and Matthias are both more the classy evil type (though werewolf and zombie seems like a great match), and he'll give Francis flashbacks to another big bad wolf that his reincarnate knew so he's gonna be super wary, but Ezekiel will probably like him lbh. Chaos? He's in.
