Mario vs Sonic

That little Blue Ball o Shit would KICK Marios Ass.
Anytime Anywhere Anyplace.

KICK

LIIIIIIIEEEES!

Neither of them would beat Little Mac though. 105lbs. of terror he was.

As we saw in Smash Bros, it comes down to WOP, Samus and Kirby. All are major badasses with DK at the top of the second tier. Sonic is good at running away, because he is a coward.

WOP would bash that rodent's face in and then either burn him to death with a fireball or put on his tanooki suit and bite him, giving him rabies if he already doesnt have it.
