Predator 2 (1990) ending / spoiler
Harrigan (Danny Glover) kills the predator in the ship it came to Earth in. He finds another clan of predators who give him a musket as a "prize" for defeating predator (and also the musket shows that these predators have been hunting on Earth for generations). Harrigan leaves the predator ship before it takes off.
