Bigby Wolf is a hybrid Fable who is half wolf and half wind and lives in Fabletown in New York City. He debuts in Fables #1 — "Chapter One: Old Tales Revisited." He is the renowned Big Bad Wolf of legend, now capable of assuming human form at will. Bigby is known for tormenting pigs and girls in red hoods, but has since been trying to put those dark days behind him.
He has acted as Fabletown's sheriff and remained in his human form, mostly, for centuries. But due to Bigby's rough past, the citizens of Fabletown are slow to trust him and he has been banned from ever setting foot onto the Farm. Having fallen in love with Snow White centuries ago, he has since tried to suppress his more monstrous urges.
