My Movie Idea:
For thousands of years people of Yautja Prime enjoyed peace and prosperity until they came. Alien beings black as the night and tails like serpents crashed onto their world in a space craft. Though at first they thought it was a asteroid, the elders thought it was a sign of their people’s end, That proved false. After most of their civilization was destroyed with many last stands and with little technology they had left, they were force to became hunters, They had to adapt, change and fight, no longer a peaceful race but one to be feared, they tracked and found the nest then killed the aliens queen and took back their world, they even learned there are more of them across the stars from what little they analyzed. Now they hunt across the galaxy for worlds infested with these Xenos! Other races that come in contact with them see them as invaders, Predators of the stars sending their scouts to test their planets resources with invisible cloaking devices but they only hunt trying to lure out the real threat, the black beasts what humans will later name as Xenomorphs.
