Many Looney Tunes characters are defined by the antagonists they face in their most famous cartoons. After all, who would the Road Runner be without Wile E. Coyote?

But just because two characters, Elmer and Bugs or Sylvester and Tweety for example, are most closely associated with each other, doesn’t mean they appeared together in every outing.

Here are ten Looney Tunes antagonists who were always going after a rascally rabbit, dastardly duck or conniving canary. Can you guess which characters were always paired together and which weren’t? 

Just to clarify, we’re only talking about the original classic theatrical shorts. Good luck!
