Bigby's true form is that of a giant, eight-foot-tall wolf. In addition to his iconic "huff and puff" power, he has also inherited other abilities from his father, the North Wind. For example, Bigby is able to hold his breath for an abnormally long amount of time, making it impossible for him to drown.
