I like to keep things simple, so I could see the Alien ripping them all to shreds...It's big, powerful, fast and vicious

Even if the others aren't technically 'dead'...They would still have lost once they have been dismembered and disabled


Then Ash comes along and blows the Alien's head off with his shotgun...If he can take out demons, he can take out an Alien

The Alien could be outnumbered if 2-3 of those listed get together against it. And it can be killed too. If a wussy Predator can do it, I m sure the Werewolf could finish it off in seconds. The only factor keeping it interesting would be its acid for blood.

The Werewolf and the Alien do have speed as their assets, but one cant ignore someone like Pinhead who can stop them dead in their tracks.

It will be mighty interesting to see Pinhead square off against the Alien. Would it be hooked in chains and ripped to pieces, or will the acid dissolve the chains and the creature has Pinhead for lunch?

The Alien is badass. You cant keep it quiet if anything living is prowling near it, unless the Queen calls it back of course (like in Aliens and AvP).
Given the day, the Werewolf is no match for it. It would be a bunch of bloody fur and meat in no time at all. The Alien can be really vicious and keep coming at you, while the Werewolf spends a lot of time snarling at its enemy.
That, my friend, will always be an advantage for the Alien.

It would just... be Alien. There's no doubt about it. the alien has no real weaknesses, pain doesn't hinder it from being vicious in the least, and neither do it's surroundings. It has acid blood, so any machete slash or stab would get it on the attacker in some way and sizzle a part of them off, and it's teeth are unbreakable! It has an evil tongue too, that can pierce a skull with ease, and a slash/stab tail. It has more stealth than an invisible ant, and it's prey is always dead on the ground in about a second. PLUS, all of it's weapons and tactics are 100% natural! It doesn't even use knives or anything like the rest.

Predator....


We're talking ONE Alien here right? Not a whole nest... otherwise we'd have to give Dracula the win because he could just keep making soldiers until the war is won for him. Acid doesn't bother vampires much, only holy water. Besides, as we've seen before, the Alien could keep killing Jason over and over again and it wouldn't matter because he would keep coming back.

But alien could stake him with his tail.

Alien could tear jason to pieces, him coming back to life holds no significance in one fight.

His tail isn't made of wood.

I don't think it matters

Depends on the lore you're going by... I agree with the legend of the "must be wooden" stake. In some cases, any stake will do; in others, it must be wood; and to get the greatest possible damage done, the stake must be made of hawthorn, ash, juniper or hawthorn.
