Knuckles and Sonic vs Mario and Luigi?

I believe it will come down to Luigi and Knuckles. Because Luigi and Knuckles are kickass, even though they arent the main characters(SEGA and NINTENDO).

Knuckles and Sonic would win

Sonic and Knuckles with ease. Mario will never be able to lay a hand on Sonic and Knuckles will knock Luigi out.

knuckles and sonic...........

Well, everyone finally agrees on something!

sonic and knuckles, a great game too.

oooo I love that game!

sonic and knuckles

Well, that was settled fast

Sonic and Knuckles will win

Will no one even use devil's adviciute (sp)

Yep, Knuckles and Sonic would take them. Mario might have some better games but he couldn't catch up to those two.

Luigi still rocks!!

Poor Mario and Luigi. Still, when the dust settles they may be beaten, but I still feel they will survive the test of time far better...

Sonic and Knuckles are cooler because....

Sonic alone would take the two. Mario jumps into the air, sonic crouches and goes all spinny spiny, mario lands on the rotating ball of blue sexy and dies. Luigi is killed brutaly by supersonic for macking his chick. lol
