The Wolf is a character who appeared in the original shorts. He is a dark gray wolf with whom Calimero had a few run-ins. Calimero initially called him "puppy" and "wolf-dog" which made him confused and upset, and later got him shot at by a doctor after Calimero convinced him he was sick in "Calimero and the two Wicked Fellows". He also appeared in "Books and Motors" where he co-conspired with Mr. Fox to cheat in a go-kart race by throwing nails on the track to mess up the other racers. Oddly he did not seem to remember Calimero getting him in trouble previously. Either that or he forgave Calimero.
