Bigby often comes across as gruff, and has difficulty connecting with others, often closing himself off to the people around him. This attitude complicates his work as sheriff, making him appear indifferent to the plights of the fables he is meant to protect and serve. He is not afraid to use force in a confrontation, making many people fearful of him. He does, however, have a compassionate side for those he loves. Bigby primarily stays in his human form to blend in with the Mundies. He has shoulder length brown hair, amber eyes, and perpetual stubble. Even in his human form, he has far hightened senses beyond those of humans, and often chain smokes in order to counteract his sharp sense of smell. When in his half-wolf form Bigby's eyes turn yellow, his teeth and nails sharpen into claws, and his physical abilities receive a major boost. This is his go-to combat form for fighting other Fables. It grants him heavily increased physical strength, agility, and endurance without causing massive property damage. When in his true wolf form he is a massive, dark grey wolf that stands at roughly eight feet tall on all fours, is capable of slaughtering entire armies with ease, and has powers of wind-manipulation due to his father being the North Wind. He only shifts into his true wolf form in the most dire of circumstances. Bigby Wolf is pragmatic, cunning, competent, gruff, stoic, and usually even-tempered despite his animal nature. Even after all his years as the sheriff of Fabletown, he is still a bit anti-social, and can sometimes appear inconsiderate to the plights of the Fables he's meant to protect. He can be sarcastic, uncompromising, blunt, distant, cynical, impatient, and distrustful. He holds all but his closest friends under scrutiny, and is willing to intimidate, harm, and even torture anyone that is a threat to Fabletown's security or, more importantly, his loved ones. He can come across as gruff, brutish, and certainly intimidating, but he is a firm believer in the law and due process.
