The Creeps

Honorable Mentions

I would if I could include the Gaming Pastas but I don't see them making it due to legal issues. Something just tells me Nintendo and Sega wouldn't be too keen on having a possessed Link and demonic Sonic fighting to the death in someone else's game. The best I can do is possibly squeez the screams from Suicide Mouse into the backtrack of the games stages.

But as for people whom can make it in as guest characters...
