Xenomorph

The Xenomorph Alien is a hostile fictional extraterrestrial monster of unknown origin from the Alien universe, designed by the Swiss painter H. R. Giger. The Greek word xeno means alien (not to be confused with the name of unknown extraterrestrial life) and morph means "form", a Greek term that should not be confused with the English "morph". In other words, the word xenomorph itself means little more than "alien form" and it was coined by a UA Colonial Marine in Aliens and they are called "serpents" (although they are not snakes) in the Alien Vs. Predator movie.

Characteristics

Xenomorphs are roughly humanoid with a skeletal or insectoid appearance. They have an elongated, cylindrical head with no eyes and a secondary jaw which can extend from the mouth, all inside a black exoskeleton.

Their prehensile tail has a sharp blade-like tip and their claws are sharp. Their blood is highly acidic. To adapt to an environment they gestate their young in hosts who live in the local environment (Alien & Aliens = Humans; Alien 3 = Dog/Cow (Special Edition); Alien Resurrection = Humans; Alien VS Predator = Predator.)

Xenomorphs can produce a thick, strong resin, used to cocoon victims and build hives. Socially and politically, they are hive-minded like a caste system and are ruled by a queen. They reproduce as parasitoids, and grow to full size very rapidly.

They are quick and agile, and can run along ceilings and walls. They can survive in extreme temperatures, are well-adapted to swimming, and can survive in a vacuum for short periods. Their movement tends to be silent, and they do not radiate heat as their exoskeletal temperature matches ambient temperature. They salivate profusely, and are extremely aggressive and persistent, while being totally devoid of fear. This is all combined with what seems to be an intelligence, especially exhibited by the queen. The 'slime' that is constantly seen dripping off of the xenomorphs is written off by cast and crew as the xenomorphs way of helping it maintain a low body temperature

Life cycle

Egg

The egg is the xenomorph's first stage, and it remains dormant within until the approach of potential prey, possibly by motion, vision or other unknown means. It is unknown exactly how long an egg can remain functional, but it is probably similar to a plant seed and well beyond the life-span of humans. The egg is also very large, being somewhere in the range of 2.5 feet high. The egg has root-like structure so it can gain a strong foothold on surfaces, even hanging from the ceiling. The egg hatches in the manner of flower unfurling its petals, sometimes becoming transparent. The eggs appear to have indefinite lifespans in almost any environment.

Facehugger

After hatching from the egg, the creature has the rough appearance of a large tan crab, minus the claws, with a tail resembling a human vertebral column. In this form, the alien's purpose is to find an appropriate host in which to lay an embryo.

When an appropriate host has been found, the facehugger, as its name implies, attempts to grab onto its victim's head. Once attached, it renders the victim unconscious by choking it with its tail and glues its legs in a locked position, after which it keeps the host in a comatose-like state. An implantation tube is inserted into the victim via the throat, through which it is fed oxygen, nutrients, possibly sedatives and parasitic zygote is implanted into the chest cavity. Once impregnated with the seed, the facehugger drops off and soon dies. The process of impregnation takes several hours.

Zygote/Gestate/Seed

The parasitic developmental stage of the xenomorph. Once free from the sedative effects of the facehugger stage, the host regains consciousness and seems normal. The exception being their entry into a hypermetabolic state, akin to pregnancy. The gestate feeds off the host's metabolism increasing his total metabolic turnover.

It is also possible that the parasite secretes hormones increasing the hosts strength, perception, emotional wellbeing; all these effects furthering the survival of the host until 'birth'. In addition adult aliens will not attack hosts, and will even protect them, often by encasing them in cocoons within the hive - encased hosts may be sedated by parasite hormones, rather than excited. Storing already infected hosts in the hive may to lure potential hosts into the hive for an ambush.

The length of gestation appears to be dependent on several factors including host health, trauma to the host, and the amount of nutrients supplied to the host. It can be as short as half-an-hour from regaining consciousness to several days or weeks.

Chestburster

Once its gestation is complete, the parasite proceeds to chew through the host until it emerges from the upper torso, in spectacularly sudden and gory fashion, thusly earning its name. This is extremely painful and fatal to the host. At this point the alien resembles an insect larva and is only about two feet long. Chestbursters have been documented both with and without 'arms' (front limbs).

When in the presence of hostile lifeforms it hides as soon as possible, as it is quite vulnerable at this stage and its only weapons are its teeth. If in a protected environment, the host's dead body provides a food source for the larvae, accelerating its maturity. Regardless, a chestburster only needs a few hours to grow to its full size.

Adult

Roughly eight feet tall, this is the xenomorph once it reaches its full state of maturity. Aliens are born to a specific caste (Queen, Drone etc.), no further post-maturity progression is known to occur. Some adults have a transparent cowl covering their ridged forehead (the one documented on board the Nostromo (spaceship) being the prime example), while others lack this cowl. While this might be related to the age or rank of the Xenomorph, no evidence regarding this has been found.

Classes of xenomorphs

Drone/Soldier

The standard xenomorph adults take on the duties of maintaining the hive. This includes building/defending the colony and securing potential hosts. In the movies, humans are the usual hosts for them while they are gestating, but there have been those that use different species.

In Alien 3, the drone was somewhat smaller and a quadruped as a result of hatching within a quadrupedal animal; this creature is usually referred to as a runner. In Aliens vs. Predator, a drone variation which uses the Predator as its host (Predalien) is also seen at the end. Both of these types of xenomorphs are further encountered in the Expanded Universe of Aliens and Aliens vs. Predator.

In the original draft of Aliens, the drone was a seperate class of small albino xenomorphs which served as a constant attendant to the queen and her eggs.

Queen

The Queen is the ruler of the xenomorph colony and is significantly larger then the standard drones. She is first seen attached to a large eggsac, but demonstrates the ability to break free when agitated or endangered. Besides the difference in size, the Queen is also covered with thicker armour, has a much larger cranium, and has two extra sets of arms.

Newborn

The Newborn is a ghastly, shambling, fleshy mixture of human and alien resulting from a genetic crossing of the two species in Alien: Resurrection. This alien has eyes and thinks Ripley is its mother, after killing its true mother, the alien queen who gives birth to it like a human. This departure from the conventional alien is one of many reasons fans criticised Resurrection, despite its screenplay by Joss Whedon of Buffy the Vampire Slayer fame.

Non-canon classes

The following classes do not appear in the movies and are thus not considered canon.

Praetorian

A royal elite guard to the queen. Praetorians are larger than standard adults, but still only about 1/2 the size of the queen herself. Praetorians appear in the graphic novel series (and the Millennium/Orion books based on the same), such as Rogue and Female War (originally serialised as Earth War). They are also a playable class in the computer game Aliens Vs Predator 2, in which they cannot "wall-crawl" like the smaller aliens, but have a bullet-resistant bio armor exoskeleton. In the game, a background report on the biology of the creatures reveals them to be a mid-point between normal drones and queens. In the video game Aliens Vs Predator: Extinction, they are hatched from "Praetorian Eggs" and can later molt to become a queen if the current queen is killed.

Queen Mother

The Queen Mother is the supreme ruling progenitor and the Queen (who is much larger and more intelligent than standard Xenomorphs) is the ruling mother of the aliens and their colonies, at least in this part of the Galaxy. She purportedly lives on the Hiveworld, (it may be the name of the Xenomorph-Space Jockey homeworld in the still-rumored Alien 5) surrounded by a group of giant, evolved royal guards. The Queen Mother's head isn't as wide as that of an alien queen, according to the comics, with a head that curves up like a blade at the back. In Genocide, after the first Queen Mother has been destroyed by Ripley in Female War, a new hive forms, which then enters competition with the old hive, both of which have spawned new queen mothers. The new hive are referred to as the "reds", although the novels explain there is no visual difference (the graphic novels do show a difference in colour, however).

Rogue

In the comic and novel Aliens: Rogue, a mad scientist engineered the Rogue: a male alien designed as a weapon to rival the queen caste and thus help rid the Earth of its alien infestation (see Earth Hive, Nightmare Asylum, Female War and Genocide). However, as befits most cases where mad scientists prove they are every bit as loony as the stereotypes dictate, the Rogue gets loose and causes havoc.

Empress

In Aliens vs. Predator 2, a variation of the original Alien Queen, the Alien Empress, was introduced. She, like the Queen, is a female and uses an eggsac to lay Eggs. What is different about her is that she has a different head design. Her head curves up to form 2 big blades and 2 smaller blades at the back. She is seen only once, in AvP2, when she is captured by the mysterious and infamous Dr. Eisenberg, who plans to use her in his bizzare experiments to combat the Xenomorphs. She is released though, when a lone Alien Drone combats Eisenberg and literally tears him apart. He is later revealed to be a synthetic.

PredQueen

In , a bizzare version of the Alien Queen is created, mixing Queen and Yautja "Predator" DNA. This version is called the "PredQueen". Not much is known about this Predator version of the Alien Queen, except that she is as strong as a regular Queen, and that she also uses an eggsac to produce Xenomorph Eggs. She looks like an Alien Queen with the apprearance of a PredAlien. She is killed when a group of Predators and a member of the Predator Ancients detonate a nuclear weapon that kills this PredHive.

K-Series

In , a variation of the original Xenomorphs are created by Dr. Samuel Kadinsky. This group is called "The K-Series", as they are almost identical variants of the Xenomorphs. All that is different about them is that they are more aggresive and have a white skin color. The Xenomorphs on planet LV-742 kill the K-Series Hive, therefore killing a difficult obstacle.

PredAlien

In all the Aliens vs. Predator games and the Alien Vs. Predator movie, the PredAlien is one of the strongest variations of the Xenomorph race. They fall into the Hybrids catagory, as they are Xenomorphs born from Predator DNA. They have Predator mandables, their will to hunt and their tentacles, but have the body of a Xenomorph and armor of a Praetorian. In Aliens vs. Predator 2, they can't Headbite, but in the expansion pack , they can Headbite, taking the whole head off.

Ravager/Carrier

In , a Praetorian can exolve into two other forms of Xenomorph than just the Queen: the Carrier and the Ravager. The Carrier Xenomorph has the ability to carry 6 Facehuggers on spikes coming out of its back. Some can even carry 11 Facehuggers. Their vulnerability is their weak armor, but their greatest advantage is the Facehuggers they are carrying. The Ravager Xenomorph's claws have the ability to kill enemies with one swipe. They can even cut through metal, and their powerful armor makes them impervious to all but the most intense assault. But it's most astounding ability is that it can actually heal itself. The problem with this is that it takes time to regenerate, and this makes the Ravager vulnerable to attack.

Variations

The Alien has been portrayed in noticeably different ways throughout the films. Much of this is due to the technology and techniques used to bring it to life.

Body shape
In the movie Alien, it was portrayed as a rather bulky creature by an actor in a large costume. By the time of Alien: Resurrection, they were depicted as much faster, more slender creatures created by computer-generated imagery.

Head shape
In Aliens the xenomorph was depicted as having ridges along its cranium. In all other movies though, it was shown with a smooth head.

Fingers
The original xenomorph had six fingers, whereas the ones in the sequel had three.

Reproduction
In Alien: Director's Cut, the alien originally had a second method of reproduction, whereby he could transform humans into eggs, as shown when Ripley discovers Brett and Dallas under the landing gear at the end of the film. This offered an origin for the eggs that didn't require a queen, which seems to have been superceded (some would say merely complemented) by the queen in Aliens. None of the other films have shown this angle. Although, in Alien 3 another addition was made: that of a "super facehugger" that could impregnate two hosts with Queen and Runner embryos and was larger and darker compared to normal. This explains why both Ripley and the dog (originally an ox took this role) was impregnated from one egg. Also, the hugger in the first cut impregnated Newt and when Newt drowned the fetus crawled from her mouth and entered Ripley. The "super facehugger" was found by some of the inmates, who thought it a type of jelly-fish.


Debate

DNA assimilation
Many believe that chestbursters, while still in an embryonic stage, use the host's DNA to augment its own and acquire any useful traits that the host garnered through natural selection. This makes sense from an evolutionary standpoint, since the host is adapted to its environment, taking on some of its characteristics would further adapt the newborn alien to its new environment. This would essentially make all adult xenomorphs hybrid creatures. This idea was used in some novel and comic book spin-offs. Another explanation could be that since the eggs seem to be produced asexually, the embryo receives some of its chromosomes from its host to allow for biodiversity of the species.

Alien 3 furthered this by having an alien embryo implanted into a dog, though it was an ox that pulled the EEV that was 'impregnated' in the original script. The xenomorphs of the first two films were all implanted in humans, and thus could walk in a bipedal formation; they also had foot-long spikes on their backs. The "dog-alien" of Alien 3 was visually very different from these, because it took on some of the DNA of its canine host. It appeared and moved in a somewhat panther-like way, did not have spikes on its back, was far more streamlined in appearance, and ran incredibly fast on four legs, rarely standing on two.

The xenomorphs of fourth Alien film were something of an exception, because they were far more human-like, to the point that the Alien Queen gave live birth to a "human-alien Hybrid": this was all because these aliens were created as the result of cloning experiments by the military, and were not the "true" form of the species, having admittedly been spliced with much human DNA. However, this was not as a result of the normal implantation-DNA assimilation process.

In various comics and the "Alien vs. Predator" video game series, this is taken a step further when a xenomorph embryo is implanted into a Yautja (Predator); the result is an Alien with Predator characteristics, a "Pred-alien". This hybrid stood on two legs, and had the basic body-outline of a Predator, having lost the elongated head shape. It also lacked the inner set of jaws characteristic of other xenomorphs, but sported a set of mandibles reminiscent of those of the Predator. This motif was also repeated at the end of the recent AvP: Aliens vs Predator film, largely based on the comic books and the video game series and written by the director of Resident Evil.

Caste/cowl
Many fans believe that the difference between the original alien from the first movie and the swarm in the second is that of a soldier alien vs. drone aliens and that the colony contains both. Others believe that there is no soldier/drone caste and that standard adults are suitable to do all needed tasks.

Most of this debate is due to the variances between the two xenomorph designs in the first and second movie, primarily the issue of the cowl. Other popular theories are that the xenomorph sheds its cowl after further maturity (xenomorphs in all movies but the second were less than three days old) or that it was simply a design choice for Aliens that had no actual significant meaning.

Endoskeleton
Some believe that the xenomorph contains an endoskeleton as well as an exoskeleton. The primary fuel for this debate is the xenomorph skull seen as a trophy in the movie Predator 2, but until AvP the two franchises were distinct, besides this nod to the Alien films. In the Aliens vs Predator comics the aliens have only an exoskeleton, but this skeleton can be bleached, e.g. when left in the sunlight (such as the queen's head trophy on Noguchi's roof at the end of Prey).

Theories

According to the computer game Alien vs. Predator 2 , xenomorphs utilize ultrasound for relatively long-distance communication. Xenomorph hives are built with smooth, rounded edges instead of rough, sharp edges because sound propagates better in such an environment. The skulls of xenomorphs act as sonic amplifiers for both boosting the transmission of messages and ensuring that incoming messages remain audible. This theory correlates with the Queen's massive head, since administrative duties would require greater transmission/receiving strength than normal xenomorphs.

The origins of the xenomorphs have never been fully explained in the films, but the expanded Alien literature has stated that the xenomorphs are bio-weapons genetically engineered by an ancient race called the "Space Jockeys". Little is known of this race except that they are purported to have created the xenomorphs to fight an ancient war. Alien eggs would be used as "bombs" on an enemy planet and then the xenomorphs would proceed to kill the entire population as they spawned. The xenomorphs were then genetically designed to die off, however eventually mutated and thrived even after killing their prey. The Space Jockeys were then killed by their own creations until none remained. A single member of the Space Jockey race escaped in a bio-weapons ship full of xenomorph eggs, but was himself infected with a xenomorph and died aboard. This is, presumably, the dead alien seen by the crew of the Nostromo. In Alien Vs. Predator, there is another origin of the Xenomorphs: one of the first human civilizations, a combination of Egyptian, Aztec, and Cambodian cultures was established with the help of the Yautja (Predators) who taught humans how to build, were worshipped as gods and every hundred years when the Yautja returned, humans were host to the Xenomorphs they hunted to show their supremacy, but a failed Hunt turned into a war in which this civilization was wiped out and the last Yautja Predator defeated the Xenomorph Aliens in a nuclear explosion. The connection between the 2 origins of the Xenomorphs is theoretically speculative and unknown.

According to a popular theory the level of development of the Chestburster is dependant of whether or not its queen is genetically compatible to the host. The eggs, which spawned the facehugger that impregnated Executive Officer Kane (and afterwards the Chestburster) of the Nostromo incident where lain by a queen that in turn came from a host belonging to the Jockey race. The Chestburster came out slightly degenerate and underdeveloped. The Chestbursters from the Hadley’s Hope incident were lain by a queen that was born from a human host (and therefore compatible with human genes) and were born from a human host. Therefore the Chestburster from the Hadley's Hope incident were more developed than the Chestbursters from the Nostromo Incident. Again the Chestburster from Fury 161 was lain by a Human-compatible queen, but was born from a dog, again coming out slightly degenerate.
