Having reformed from his violent ways, Bigby (aka the Big Bad Wolf) became the cigarette-smoking, trench coat-clad sheriff of Fabletown. He is extremely cunning and resourceful, in addition to being an excellent detective. He is the son of the North Wind, and, as such, has some control over the lower-tier winds, plus the "huff and puff" of legend. Despite his reformation, he can still be vicious if he believes the situation calls for it. He developed feelings for Snow White and the two have a litter of seven children together. He quit his position as the Sheriff some time ago (due to the election of Prince Charming as Mayor, whom he despises), and left Fabletown altogether. He has since returned and married Snow and now lives with her and their cubs on a specially set-aside area of land up at the Farm. In "The Destiny Game", Bigby forces The Lady Of The Lake to change his fate. Though he does not know the specific details (nor does he bother to inquire about them), this is his new fate : he will never grow old, but he will continue to grow in strength and power, fall in love with Snow White (a woman strong in wild magic, who will eventually confess her love for him), father seven children ("sons" and "daughters" - which implies Ghost is either male or female, not gender-neutral) - gods and monsters (in fact, part-gods, due to their North Wind grandfather and monsters, due to their wolf nature) who will lay waste to worlds (implying all of his cubs will do terrible things, eventually - though this is contradicted by Dare's suicide, for a noble cause, before he had committed any monstrous deed of any kind at all). Also, once he has died seven times, he will outlive all of his cubs (though this may only be metaphorical, as the exact nature of these words is unknown). So far, it is unknown how often Bigby has already died (if at all) - nor is it known if being shot by Goldilocks and gravely wounded, along with Little Boy Blue, during the war count as deaths.
