Luna Lovegood.
I respect Lupin as a character, but I enjoy reading about Luna far more than I do with uncle Remus.
Also the werewolf's name is "Remus Lupin"...really, Jo? Really? Fenrir Greyback's past is a little more vague so maybe he changed his name after getting wolfy...but Remus has parents, named Lupin, that gave him the name of someone nursed by a wolf for Merlin's sake!
