I think a Freddie vs Pinhead match would be interesting...
That was the original proposed ending to Freddy Vs. Jason. Jason and Freddy would wake up in Leviathan's Hell and Freddy would go to stab Jason. Right before he'd connect a chain would pull his hand back and Pinhead would be standing there telling the two they had eternity to play or something to that effect.
That would;ve been awesome! Only thing cooler would've been Ash stepping out of the shadows. He could say something like 'Which one of you freaks knows the way out of here?'
