Alien Attributes
Biology
Predators (identified as "Yautja" in secondary sources) are humanoid, but they are much larger and stronger than humans. They presumably evolved in an arborial habitat, as their climbing and leaping abilities rival those of arborial monkeys and squirrels of Earth. They prefer warm climates, but they can survive in arctic conditions. Apart from an unusual jaw structure, they seem to be skeletally almost identical to humans. They are quite tough and can withstand multiple wounds from modern firearms without severe losses of physical performance.
Technology
Predators possess advanced technology, including faster-than-light propulsion for their spacecraft. A typical hunter uses an assortment of high-tech devices, including a camouflage device that makes him effectively transparent when activated, a shoulder-mounted weapon tied to a targeting system in his helmet, a medical kit, and an assortment of collapsible spears, blades, and nets. They also carry a powerful bomb in a bracer that they use to destroy themselves and their equipment if they are close to being captured by their prey.
Brain Bug
In the 1987 movie, the "Predator" was an alien trophy hunter who used advanced technology to hunt humans, specifically targeting teams of elite soldiers who presented more of a challenge than unarmed civilians. In sequels, this individual became the model for a monolithic culture, an entire civilization of aliens who live to hunt for sport.
Predators in Debates
Predators frequently show up in debates as antagonists, with debaters speculating about how successful they would be hunting soldiers or special characters from a variety of other science fiction settings.
