Original Appearances: Looney Tunes cartoons, starting with “Don't Give Up the Sheep” in 1953.
Other Appearances: Ralph has appeared in a number of other Looney Tunes-related products since 1988, including at least one video game.
Biography: As with Sam Sheepdog, we don't know anything about Ralph's personal history.
Powers: None. He actually seems to even lack the typical cartoon character ability to rebound from any damage so long as the scene changes, as we've seen him clocking out at the end of the day all bandaged up.
Group Affiliation: Presumably Ralph belongs to a wolf's union of some kind that covers his medical expenses!
Miscellaneous: Ralph is often mistaken for Wile E. Coyote, because they look so similar. Ralph often is presented with a differently-colored nose.
