Wolves tend not to get the sympathetic roles in stories, but one good wolf character is Akela, from "The Jungle Book."
Some favorite cartoon characters, from back when I was a kid watching Saturday morning cartoons: Bugs Bunny, Daffy Duck, Wile E. Coyote, Rocky & Bullwinkle.
Yeah, I'll admit, I like Robin Hood and Marian from the animated Disney film.
My favorite, though, goes back to an old French tale: Reynard the Fox.
