Alien vs (insert your dream mashup)

Alien vs the demons from doom or Half Life's vortugants

@ali81  that's awesome lol

Alien vs Darth Vader

Walter Wins Hands Down !

Lemme think...

How about

Alien vs SCP-049

Idk

The plague mask guy huh?He kind of reminds me of Bloodborne

Yes,they are both based on the plague doctors.

I loovvvveee plague doctorssssss.

Half Life 2's Dog was pretty formidable.

Chell and her Portal gun could make for some interesting scenarios.

Great choice's.Portal is excellent.

I don't think the Alien could beat the Q Collective from Star Trek TNG. After all, it is Q.

I think the only thing that beats Q is Q.

G Man would probably find some interesting uses for the Xenomorph too if he could figure out how to manipulate it.

Alien vs the babadook

Or the Illusive Man.Maybe use Reaper indoctrination.

Alien vs Mimic "The Judas"

Cool choice Apex,Mimic is very underrated 

Alright i've been playing Bioshock(for probably the fifth time at least)and i would like to see the xenomorph infest Rapture,then we could have Alien vs. the Big Daddys.

Sorry to resurrect this one again guys.This one was suggested by my brother.Alien vs Valve's Gabe Newell.If the alien wins we just might get Half Life 3 lol.
