yes I like both characters too. They both awesome! Not sure if the predator has much of a chance though, it depends on the experience of that particular predator, and in the movies I seen, I only seen young predators in action. No idea how skilled the older ones are. But Darth Vader is strong in the dark side of the force, and he has a light saber too. Even if the Predator uses that plasma cannon, Vader would just hit it right back.
