Fang is the pet dog of Dr. Roscoff.
He is a German Shepherd painted with luminous paint.
He was aggressive when he was hungry, but Scooby-Doo made friends with him after giving him some bacon.
Dr. Roscoff disguised his dog as the Phantom Wolf to discourage curious people who might discover his secret mining operation where he used hypnotized slave labor. He kept Fang hungry in hopes that he would attack intruders.
In the end, both he and Scooby, covered in luminous paint, ride on one of the mine carts howling.
