Who's the coolest? http://www.collider.com/wp-content/image-base/Movies/A/Alien/alien_xenomorph_02.jpg http://unrealitymag.com/wp-content/uploads/2009/02/predator-1.jpg I think Aliens. They just look better than the drad-locked Predators. And they are better in sneaking up on someone.
If i had the choice to be one of them, i'd be a Predator. But i do think Aliens are just a bit cooler
