B-M-H... Since when were aliens intergalactic hunters? That's what a predator is... aliens are more like parasites and I highly doubt that your bio mechanical alien from the first film could do sh*t to the original predator, how slow that thing moved and hibernated around the ship, but without weapons not even a predator could last in a hive. Bottom line: The predators hunt and toy with aliens, if the aliens have their way, they make you extinct. Little eco terrorists!
