Of course we are talking about one Alien here. A whole nest of Aliens would kick everybody's ass listed above in a matter of seconds. But Jason has a sixth sense. Many a time in the movies we see it, as a close up to his mask and one of his eyes shining with some new light inside.

I dont think Jason would let himself be ripped to pieces so easily. And remember, the Alien doesnt tear into you right away. It tries to bite and grab first, in order to take you alive, to the nearest face-hugger egg. If the prey is too vicious, then only it responds by swiftly killing it. Jason can be a smart fighter in an one-on-one. True he doesnt have much grey cells, but yeah in a fight, even against the Alien, Jason is a tough SOB to beat.

Remember Jason wears a hockey mask. The view to the Alien itself would convince it that this one cant be dragged back to an egg. It would be a fight alright. And the Alien definitely has a lot of edges over Jason, if it comes down to a fight between em.

Dracula..
those other young bucks would be no match against a man who can mesmerise and hypnotise ..
a man who can change form and pick his time of attack.
a man who can decide at his own leisure whether to turn you into a living dead
or just devour you outright.
'sigh'..i so love the man :o

Valid points. But the question is, can the Alien be hypnotised into submission? If the answer is yes, even Freddy can beat it.

Dracula is a huge match for the Alien. I dont think it would know how to encounter a vampire. Treat him like a human or an animal? And the ripping to shreds approach wont work with Dracula, especially at night.

I side with Jason. No matter who the opponent is, Jason can take on anyone on his day, and win.

I would love to see a movie setting like Pitch Black with a ton of Aliens vs. a whole army of the undead raised by Dracula. I'm talking kick-ass vapires too, wolf/mist/bat forms and whole deal.

Oh sheesh. One alien is hard enough, but an army? Alien still.

Vs. an entire army of the undead which could fly above the Aliens, study their movements, use mist to come up right behind them and then their super strength to literally tear them apart. It would be fun to see. Or one Alien vs. the crazy ass cyber Jason from Jason X heh.

But as far as I know, not all the vampires can make mist and stuff, just dracula. But the thing is, in a war, nature ALWAYS wins. You just can't defeat it. And aliens behave naturally and instinctively, just as the vampires would study them, the aliens would be studying just as hard. Plus the queen reproduces extremely fast, and any stupid vampire that lands on the ground would get a nice facehugger surprise.
