Dont' forget we have a lot of characters, from a lot of different worlds and ideologies. Maybe we have multiple Predators in a lot of locations.
"If you think of the first Predator as Alien, ours is much more Aliens," said the film's co-writer Fred Dekker. "It's not Ten Little Indians; it's not, 'Let's kill off all of our characters,' because we have a lot of characters, from a lot of different worlds and ideologies. I don't mean other planets. It's a lot of people doing a lot of things in a lot of locations."
