Ralph Wolf and Sam Sheepdog

Ralph E. Wolf is a rival to Sam Sheepdog. Ralph Wolf is nearly identical to Wile E. Coyote, only Ralph tries to catch sheep from Sam's flocks and his nose is red in color, while Wile E's is black. Sam always saves/protects the flock, Ralph always getting injured in the process. He has recently appeared in Sheep Raider (AKA Sheep Dog n' Wolf) for PS1 and PC, where you use numerous ACME products to steal sheep without alarming Sam Sheepdog.

Trivia

 * Ralph looks just like Wile E. Coyote. However, the only exceptions are that Ralph has a red nose and tries to steal sheep instead of trying to chase roadrunners.
 * Ralph is the main protagonist of Sheep Raider.
 * Ralph's middle name is similar to Wile E. because their middle name is both the letter E.
 * Ralph made a cameo appearance in Looney Tunes: Back in Action where he sits at a dining table and shows his rival Sam Sheepdog that he finally got a sheep from him and is about to eat it when Sam grabs him by the neck and punches him several times in the face.
 * Unlike most of the antagonists of Looney Tunes, Ralph's interest in the sheep is treated like as a job. Many episode featuring him and Sam will have them greeting each other and punching a time clock before starting their usual roles.
