Xenomorph XX121, commonly referred to as simply the Xenomorph and known colloquially as the Alien, is a highly aggressive endoparasitoid extraterrestrial species. The Xenomorphs are vicious predatory creatures with no higher goals than the propagation of their species and the destruction of any life that could pose a threat to them. Like wasps or bees, Xenomorphs are eusocial, with a fertile Queen breeding a host of subordinate castes. The creatures are known for their potent acidic blood and their pharyngeal jaws, although their biological life cycle, in which their offspring are implanted inside living hosts before erupting violently from their chests, is in many ways their signature aspect.

The original Alien design is credited to Swiss surrealist and artist H. R. Giger, originating in a 1976 lithograph called Necronom IV and refined for the series' first film, Alien, in 1979. It deliberately evokes many sexual images, both male and female, to illustrate a blurring of human sexual dichotomy. The mechanical head-effects for the original creature were designed and constructed by Italian special effects designer Carlo Rambaldi. The species' design and life cycle have been extensively added to throughout each subsequent appearance, while continuing advancements made in the field of special effects technology have led to numerous variations in the creature's design.

Aside from their repeated conflicts with humans, Xenomorphs have notably been associated with the Yautja (Predators), leading to the extensive Alien vs. Predator franchise, including the films Alien vs. Predator (2004) and Aliens vs. Predator: Requiem (2007). The Xenomorph has also featured heavily in numerous literature and video game spin-offs, including crossovers with other well-known franchises.

Damn... 1976? I didn't realize how old Alien is until I had to type that. Yet another old school movie character as a guest character in Mortal Kombat? Fair game. Alien fits into MK... pretty well. Ever since MK9, NetherRealm has been pushing the "horror" genre into MK, as the gore and violence Xenomorph brings to MK seems well suited. Alien's MKX moveset is a weird mix of things. Some of his basic animations are okay, but in typical NRS fashion, many of Alien's key animations are stiff and just seem "off". For one, his "backstroke" swimming special move looks silly as hell. I'm not trying to nitpick, but in my eyes, MKX Alien moves more like a NRS-animte human than it does an actual Alien. He should do more creepy crawlin'... y'know? Also, where's the "weight" of his tail in his MKX animations? I don't see it. :( Anyhow, I like Alien's animations better in Capcom's 1994 2D sidesroller. See below.
