RE: ok this is WAY off topic but...
Probably the T-101 Terminator overall. Freddy couldn't attack the Terminator because he doesn't dream and if he could the Terminator would cut him apart blow him apart. Freddy's metal, spikey gloves would be like trying to hit a person with foam, it wouldn't be effective.
Rambo and Hannable would be killed as said before due to being mortal before too long.
I can't see anyone by themself killing the T-101 because it took both Kyle Reese and Sarah Conner to terminate the Terminator and they needed a compression machine in order to finish him off, and Kyle was killed before the terminator was.
In Jason X, Jason was defeated by being shot with a machine gun which blasted off his limbs. He would have stayed defeated if it wasn't the nanobots who fixed him. Like I said earlier, I don't know about the other characters but I don't they could defeat the T-101 by themselves. The Terminators take a lot of strategy to defeat and some extremely powerful weapons.
