Alien vs. Predator, or Aliens versus Predator (both titles abbreviated AvP), is a science fiction / horror fiction series spanning several forms of media. The series is a crossover between two famous film franchises about extraterrestrial beings: The Aliens and the Predators. In Alien vs. Predator, the two species are in conflict with one another.
The idea for such a crossover is often thought to have originated from a Xenomorph's skull seen as a Predator's trophy in Predator 2, but Dark Horse Comics published their first Alien vs. Predator story in November 1989, one year before the November 1990 release of Predator 2.
Currently, the Alien vs. Predator universe consists of comics, novels, computer/video games, and feature films (all in which the rights belong to 20th Century Fox studios).
