Knuckles vs. Little Mac

YAY! My first fan art drawing!!!! I always wanted to draw Knuckles since he's my favorite Sonic character. The only thing was that I needed a backdrop. So, of course, Punch Out! for the Wii came out and it dawned on me:

"Both Knux and Mac were in Smash Bros. Brawl, yet neither of them were part of the playable characters' roster!"

And thus the "Un-sung Brawl" was born!!! So with that being said, who do YOU think will win!?
