Predators (known in the fictional expanded universe as Yautja or Hish-qu-Ten) are a fictional species featured in the films Predator (1987), Predator 2 (1990), Alien vs. Predator (2004) and the upcoming Aliens vs. Predator (2007). The creatures also feature heavily in various other media including comic books, graphic novels and video games. Originating as the antagonist in the Predator sci-fi horror films, they are vaguely humanoid aliens who hunt the aggressive members of other species for sport.
Predators are depicted as an extraterrestrial race whose civilization seems to focus on individual strength, exemplified in the concept of hunting. They are depicted as excellent warriors, pursuing the most dangerous species in the galaxy. Predators stalk and kill prey using various armaments, ranging from high technology smart weapons to low-tech blades and spears. Once they have defeated an opponent, they collect the skulls as trophies and mark themselves with the symbol of their clan (mark of honor). Predators have a long and involved history with many species they hunt, including Xenomorphs. Although the morals of their race are unknown, they appear to have some consistent form of honor. This is usually depicted showing respect and acknowledgment to powerful adversaries as well as an unwillingness to stalk weak, sick, or unarmed opponents.
