Link/Ganondorf
Mario/Bowser
Sonic/Knuckles (Or Robotnik)
Solid Snake/Liquid Snake(Or Ocelot)
X/Zero
Mega Man/Wily
Samus/Ridley
Left Pong Paddle/Right Pong Paddle
I'm expecting a really exciting contest, you see.
If a miracle occurs, replace Mario/Bowser and Sonic/Knuckles with Mario/Sonic and Sora/Riku
Edit: Wait, forgot about Charizard/Blastoise. Put them over X/Zero, and X/Zero over Sora/Riku.
