Who would prevail: These creatures vs....: Predator, Alien...
Raptors, T-Rex? Tough to say, wouldn't it? I'm really not sure who would be the last creature standing in a death match....Opinions?
sharePredator would slaughter these creatures. Predators hunt and kill Xenomorphs (that's what the Sigourney Weaver aliens are called), and Xenomorphs are deadlier than these things.
Raptors wouldn't stand a chance. T-Rex could probably take one down.
