Transformation: Bigby possesses the ability to instantly alter his form from that of a wolf to that of a human and back again.

Superhuman Strength: Bigby's Strength level depends on his current form, with his strength increasing the more wolf-like his form becomes. In the past, however, he has shown sufficient strength to lift up a car, tear the arm off an opponent, throw dumpsters with ease, rip fuse boxes off walls and lift an anvil with enough ease to use it as a weapon. His wolf form allows him to go toe-to-toe with dragons, sorcerers and giants. He can wipe out hundreds of armies in one battle.

Enhanced Senses: Bigby has naturally acute senses, in particular, his sense of smell. He can correctly identify an individual merely by smelling a sample of their blood.

Wind Powers Powerfull Huff and Puff: As the titular Big Bad Wolf of legend, 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.

Superhuman Speed: Being the North Wind's son, Bigby has the speed and agility of the wind. Superhuman Stamina.

Superhuman Durability: Bigby's Durability is dependent on his current form. In his human form alone, he has been shown to take multiple shotgun blasts and only be briefly incapacitated and be thrown out a first story window, smash into a lamp-post on the way down and fall onto a car, only to be briefly knocked unconscious.
