Marvin the Martian

From HallsWiki

Marvin the Martian is an occasional star of the Looney Tunes cartoons, who has become increasingly popular as time goes on. There's something about a put-upon midget with dreams of destroying the Earth that just resonates with people, it seems. But Marvin is always foiled by Bugs Bunny or by Daffy Duck in his guise as Duck Dodgers, so the Earth is safe... for now.

Marvin was a semi-finalist in the Battle of the Looney Tunes.
