The final fight(at least my idea of it.)
 

heres how it would roll if Leatherface, Freddy, Jason, Mike, and Pinhead were to fight. I think Jason and freddy would split up and Jason would take on Leatherface, Freddy on Pinhead. Now Freddy would beat Pinhead being that freddy is smart and would be able to solve the puzzle that was opened (how or when it would have been opened we dont know) , then Leatherface would grapple up with Jason, eventually fighting into a cabin, slamming each other through walls (we know that both arent too smart so it would be a strength battle) Jason would eventually just over power Leatherface due to the fact that hes showed more power in his movies. Jason would take leatherfaces mask and put it over his own as sort of a prize. Then Freddy and Jason would duke it out until they eventually reached the end where JAson would walk out victorious aftertrapping freddy in the cube with hellraiser so we know Freddy would show up agian in possibly another hellraiser movie. This would be the only true showing of brains from Jason.

Hey id like some feedback if you think this would make a good movie cuz i might write it all out.

You underrate Pinhead. He's the most intelligent of the four and I think that would outweigh brute strength. I think it would come down to Jason VS. Pinhead.

I dont know i think freddy is pretty damn smart, Pinhead may be sadistic and twisted but he has been outsmarted by just as many people as freddy. I don know Jason would make it to the final tier though, I mean come on the guys a powerhouse. Plus Id like to see some brains at the very end I think fans would respond well to that in the least.

well in the first FvJ jasons mom told him that he couldnt ever die so theres no way jason we'll be killed because of that

the way i see it from an objective point of view is that pinhead would tear them all apart like it was playtime. i mean the man is a demi god and pretty much the most powerfull being in horror

yeah but to beat him you just have to reform the puzzle, and besides would any of this involve the other sprites.

never mentioned any other spirits, its just my opinion though from what iv seen, i mean leatherface is just a mortal, freddy is good, jason is better but putting pinhead against them all... i would call it an uneaven fight, hes straight from hell and kill them all in uncountable ways, he doesnt have to get close to anyone, he can just snap his fingers and its over and done with.

true but he does get cocky and he makes mistakes and thats what the other killers thrive on their enemies mistakes and like you said earlier Jason cant be killed. its a proven fact. lol

hehe, well maby jason cant be killed but im not sure how much of a threat hed be if pinhead took his arms and legs off, ontop of that hes been laid to reast more then once so to speak, solving the puzle to kill pinhead doesnt stirke me as something you just do... it seams a bit more complicated then that

i think so 2 but jason would come out of it victorious
