The Big Bad Wolf is a fictional character from Brothers Grimms' Fairy Tales.
In the Fables Universe, Bigby Wolf is a werewolf and the sheriff of Fabletown. Once the villain who terrorized various fables like the Red Riding Hood and the Three Little Pigs, Bigby reformed himself, married Snow White and served as the sheriff for the Fable community for a long time. His father is the incarnation of the North Wind and his mother is Winter. He earned the name "Big Bad" after his siblings noted his drive to be ferocious, particularly after his father left his mother. Due to his parentage, Bigby can "huff and puff" powerful hurricanes from his mouth. This power is strong enough to demolish whole forests, armies and big infrastructures and building.
In the Prime Earth continuity, "Big Bad Wolf" is an alias used by a Green Arrow villain named Dolph Marrock, a criminal who was infected by Lukos; a disease that when untreated slowly mutates people.
Bigby Wolf was created by Bill Willingham and Lan Medina, first appearing in Fables #1 (2002). Dolph Marrock was created by Benjamin Percy and Szymon Kudranski, first appearing in Green Arrow Annual (Volume 5) #1 (2015).
