Predalien

The "PredAlien" is the product of an Alien Facehugger impregnating a Predator, or in rare cases, an after-result of genetic experimentation. Fan opinions on its appearance seem to range from approval to total hatred. Some believe the Predator's fleshy dreadlocks should not have been included, as Xenomorphs seem to retain more of their host's skeletal structure than flesh; some even argue that the mandibles, which obviously have bones within them, should have been excluded, effectively rendering the PredAlien a stronger, bulked-up version of the human-incubated Drones often seen in the movie.

The AvP games have, however, shown a creature more in touch with its Predator host: complete with large mandibles, a heavily-built physique, and dreadlocks - even going so far as to shorten the elongated head and apparently remove the inner set of jaws. In the games, this variant is also depicted light brown, much like the skin-color of the Predators. In reality, it shares more of a resemblance with its host than other xenomorphs.

The PredAlien's status as a non-canon caste is actually debatable, however, as a chestburster was seen in the end of the Alien vs. Predator movie emerging from the Predator "Scar". It possessed the mandibles of a Predator, and may grow up to resemble the PredAliens of the game, or even a PredQueen, if it appears in the sequel. a sreenshot released on alien vs predator 2(film) shows a predator fighting an alien that has a distinct new look. Of course, many fans seem to question whether the movie itself is canon, so the PredAlien's place in the Alien and Predator franchises is still up for debate. However, Alien vs Predator takes place before Alien and could be canon, the predators could have killed the predalien chestburster.

In the game the predalien is not able to headbite, however, in Aliens versus Predator 2: Primal Hunt the predalien is capable of using its mandibles to instantly crush and consume the head of a foe (it is likely this addition was made due to the fact that the predalien is the only class playable in the single-player campaign, and headbiting restores a large amount of health, far more than from simply clawing at a corpse).

In Aliens versus Predator: Extinction, the PredAlien has a reddish exoskeleton and the ability to secrete growth hormones during battle, making it molt and become more powerful afterwards.
