Powers and Abilities
Bub is probably one of the (if not the) most powerful and dangerous villains in the series. He possesses vast demoniacal powers, such as teleporting, turn into mist, create fire, shoot beams with his staff, control weather, bring down the amount of destructive lightning, cause earthquakes, and especially send anyone into Hell. He also shows superhuman strength, speed, and durability, and he is obviously immortal. Bub is also very cunning and a skilled manipulator. He is finally a great dancer, though inferior to The Mask.
