The "Alien" (also referred to as a "Xenomorph") is a fictional endoparasitoid extraterrestrial arthropodal species that is the eponymous antagonist of the Alien film series. Just as depicted in the Aliens vs. Predator games, the Xenomorphs can also detect their prey using pheromones. Another theory is that the eyes of a Xenomorph are behind their black carapace and they see through it, similar to a one sided mirror (except in this case no one can see in, but the Xenomorph can see out).

Hans Giger, the Oscar-winning artist who designed the creature in Ridley Scott's sci-fi horror classic "Alien", died at age 74 from injuries suffered in a fall in his museum in May 2014.
