Question:
Apparently the Predators 'made' the Aliens to be the ultimate enemy but was this an afterthought after putting the two franchises together or was it in the original stories.
Were the Aliens made/invented by the Predators or were they found somewhere and bought back as prey?
In the first AvP I think the whole idea was that they built that tomb thing for them to come to earth and train their young predators against the 'ultimate' adversary.
It was like a massive training course that activated at certain times to produce aliens for them to hunt and train against.
i dont remember them being cross referenced in the original individual films, so i imagine it was an afterthought, a way to justify making the AVP films.
There was also a reference in Predator 2 that the two species had met before when Danny Glover goes on the ship at the end and sees the Alien head skull on the wall.
