I'd say Meta Knight. The reason I chose him instead of Lucario is solely because he can attack way faster, and thus Chuck Norris can't attack as much because of Meta Knight's very fast slices. But who do YOU think could win? :D
Hah, speed ain't nothin' if you go against my C.Falcon. Someone tried beating me with Sonic's speed alone.
He ran face-first into a Falcon Punch. PWNED!!!
But honestly, Falcon and Norris are evenly matched.
Which would you hate more, 10 dead babies in 1 trash can, or 1 dead baby in 10 trash cans?
