Wile E. Coyote is a cartoon character from the Looney Tunes series of cartoons, whose sole purpose in life is to catch and dispatch the Road Runner consistently and constantly failing in his efforts, of course, and receiving the injuries himself. For this purpose he purchases increasingly ludicrous and unfeasible contraptions by mail-order from the ACME mail-order supplies company.
Wile E. Coyote appears in the series in his Chuck Jones animation and as of 2012, his The Looney Tunes Show cel-animation style and his computer-animation stype (only one shot). He never spoke but had one line in his Chuck Jones form. Seth MacFarlene provided Wile the line.
