The Predator is a fictional extraterrestrial species featured in the Predator science-fiction franchise, characterised by its trophy hunting of other dangerous species for sport, including humans and its fictional counterparts, Aliens.
First introduced in 1987 as the main antagonist of the film Predator, the Predator creatures returned in the sequels Predator 2 (1990), Alien vs. Predator (2004), Aliens vs. Predator: Requiem (2007), and Predators (2010). The Predators have also been the subject of numerous novels, video games, and comic books, both on their own and as part of the Alien vs. Predator crossover imprint. While a definitive name for the species is not given in the films, the names Yautja and Hish have been alternatively used in the expanded universe.
Created by brothers Jim and John Thomas, the Predators are depicted as large, sapient and sentient humanoid creatures who possess advanced technology, such as active camouflage and energy weapons, and are capable of interstellar travel.
When a Predator is impregnated by a facehugger, this will result in the creation of a hybrid caste known commonly as the Predalien. The Predalien shares many characteristics with its host, such as long hair-like appendages, mandibles, skin color and similar vocalizations. It is a large, bulky creature, and possesses physical strength greater than that of human-spawned Aliens. Like human-born Aliens, it is also shown to be stronger than its host species, as evidenced by its ability to pin, push, and knock a Predator away with ease. It also possessed the ability to impregnate human hosts with multiple Alien embryos.
Predators consider these caste as abominations that defiled their sacred bloodline and therefore must be destroyed.
