 during the gestation period, the Alien also takes on some of the basic physical attributes of the host from which it was born.

Queen

Queen Aliens are significantly larger and stronger than the warriors, approximately 4.5 metres (14.8 ft) tall. Their body structure differs also, having two pairs of arms, one large and one small. The queen's head is larger than other adult Aliens and is protected by a large flat crest. Unlike other Aliens, the queen also has high heel protrusions from its feet. The queen also seems to have increased intelligence compared to the other forms of the xenomorph, as the queen on LV-426 was able to learn to operate an elevator. Pregnant Alien queens possess an immense ovipositor

 of the film, have since said that this is a stage between adult and queen known as Praetorian, by which a young queen attempts to quickly build its army before it grows the egg sack and cannot defend itself.

In the initial cut of Alien, the Alien possessed a complete life cycle, with the still-living bodies of its victims converted into eggs. However, the scene showing this final stage was cut for reasons of pacing, leaving the ultimate origin of the eggs obscure. This allowed Aliens director James Cameron

The design of the queen was created by Cameron in collaboration with special effects artist Stan Winston

Although at the end of the film the queen was presented full-body fighting the power-loader, the audience never sees the legs of the queen, save those of the small-scale puppet that appears only briefly. In Aliens, Cameron used very selective camera-angles on the queen, using the 'less is more' style of photography. Subsequently the movie won an Oscar for Visual Effects

the queen's basic design was altered to make it more "streamlined" in appearance and its over-all size was increased to 6 meters (20 feet) tall. Other changes include the removal of the "high-heel" protrusions on its legs, including additional spines on its head and making its waist thinner because there was no need for puppeteers inside its chest. The animatronic laying queen had 47 points of hydraulic motion.

Egg

The eggs laid by the queen are large, ellipsoidal leathery objects between two to three feet high with a four-lobed opening at the top. As a potential host approaches, the egg's lobes unfold like flower petals, and the parasitic facehugger extracts itself from the egg and attaches itself to the potential host. Giger initially designed the eggs with a much more obviously vaginal appearance, complete with an "inner and outer vulva". The producers complained that Catholic countries would ban the film if the allusion was too strong, so Giger doubled the lobes to four, so that, in his words, "seen from above, they would form the cross that people in Catholic countries are so fond of looking at." The interior of the original egg was composed of "Nottingham lace", which is the lining of a cow's stomach. In the first film, the quick shot of the facehugger erupting from the egg was done with sheep's intestine. Initially the egg remained totally stationary save for the hydraulic movement of the lobes; however, by Alien Resurrection the entire egg was made to ripple as it opened.

Facehugger

A facehugger is the second stage in the Alien's life cycle. It has eight long finger-like legs which allow it to crawl rapidly, and a long tail adapted for making great leaps. These particular appendages give it an appearance somewhat comparable to chelicerate

; its only purpose is to make contact with the host's mouth for the implantation process, by gripping its legs around the victim's head and wrapping its tail around the host's neck. Upon making contact, the facehugger tightens its tail around the host's neck in order to render it unconscious through oxygen deprivation. The facehugger then inserts a proboscis

 down the host's throat, supplying it with oxygen whilst simultaneously implanting an embryo. Attempts to remove facehuggers generally prove fatal, as the parasite will respond by tightening its grip, and the facehugger's acidic blood prevents it from being safely cut away.

Once the Alien embryo is safely implanted, the facehugger detaches and dies.

Giger's original design for the facehugger was a much larger creature with eyes and a spring-loaded tail. Later, in response to comments from the filmmakers, Giger reduced the creature's size substantially. At first Giger assumed that the facehugger would wrap around the outside of the astronaut's helmet, but Scott decided that it would have far more impact if the facehugger were revealed once the helmet was removed. Scott and Giger realised that the facehugger could burn through the helmet's faceplate with its acid blood; subsequent redesigns of the space helmet included a far larger faceplate to allow for this.

 sculpture of the facehugger was produced, O'Bannon asked that it should remain unpainted, believing the rubber, which resembled human skin, was more plausible.

In Alien 3, another addition, a "super-facehugger" that would carry the embryo of the queen Alien, was planned but ultimately dropped. The super-facehugger is briefly glimpsed in the Assembly cut of Alien 3, but not identified as such.

Chestburster

After implantation, facehuggers die and the embryo's host wakes up afterwards showing no considerable outward negative symptoms. Symptoms build acutely after detachment of the facehugger, the most common being sore throat, slight nausea

The incubating embryo takes on some of the host's DNA

s of a Predator and other body structure changes. Over the course of 1–24 hours, indeterminable in some cases, and sometimes up to a week, in the case of some queens, the embryo develops into a chestburster, at which point it emerges, violently ripping open the chest of the host, killing it.

 and constructed by special effects artist Roger Dicken. Giger had produced a model of a chestburster that resembled a "degenerate plucked turkey" and was far too large to fit inside a ribcage. Much to Giger's chagrin, his model reduced the production team to fits of laughter on sight. Scott drafted a series of alternate designs for the chestburster based on the philosophy of working "back [from the adult] to the child" and ultimately produced "something phallic." The chestburster in the original Alien was armless but arms were added in Aliens to facilitate the creature crawling its way out of its host's corpse. This concept would be abandoned in Alien Resurrection and subsequent films.

Growth and maturity

When a chestburster erupts from the body of its host, it is less than 1 feet (30.5 cm) tall. However, it soon undergoes a dramatic growth spurt, reaching adult size in a matter of hours; in Alien the chestburster had grown to 2 metres (6.6 ft) in height by the time the Nostromo crew located it again. The chestburster is shown to have molted before reaching maturity. In Alien vs. Predator: Requiem Alien warriors are shown who are still growing, showing shedding skin. In the unrated cut, the Predalien is shown actively wiping off its final molted skin at the film's start. A shed skin of a growing chestburster is also shown, showing that the creature's final limbs do not grow in the earliest stages.

"Dog Alien"

The "Dog Alien" (also jokingly referred to as the "Bambi burster", or "Runner Alien" in the expanded universe stories), was introduced in Alien 3. The creature itself shares the same basic physical conformation and instincts as the other Aliens shown in the previous films, although there are several differences due to the host from which it was spawned (a dog

 hind legs and lacks the dorsal tubes of the human-spawned variety.

"Newborn"

In Alien Resurrection, due to significant genetic tampering in an attempt to recover DNA from the deceased Ellen Ripley and the Alien Queen within her, the resulting cloned Aliens show a number of minor human traits. The cloned Queen inherits a womb, and as a result it ceases to lay eggs and gives birth to a humanoid mutant. Physically, the human-Alien Newborn is very different from its brethren, being larger, with pale, translucent skin, a skull-shaped face with eyes, a human tongue and complete absence of a tail. The Newborn fails to bond with its Alien Queen mother, and kills it. Instead, the Newborn sees the Ripley clone as a surrogate parent.

The Newborn creature was originally scripted by Joss Whedon

Like human-born Aliens, it is also shown to be stronger than its host species, as evidenced by its ability to pin, push, and knock a Predator away with ease.

Mutated chestburster

A mutated Alien variant incapable of maturing past its larval stage, the mutated chestburster resembles a large black Chestburster. Hatched from a pink egg among an ordinary clutch, the mutated chestburster's egg was smuggled to the pleasure planet Celeste, where the resulting hatchling, after escaping from a human host, caused havoc among the population with its diseased slime trail, which caused people to go delirious and detonate.

White Hybrids

The hybrids are a race of Aliens created by a corrupted computer system called "Toy". The hybrids possess the traits of Aliens, Predators and humans. Like Aliens, they are a eusocial species with acid for blood (though it is less acidic than that of the ordinary strain) and like humans, they are capable of speech and can use firearms. They are led by a hybrid king which generates facehuggers capable of impregnating ordinary Aliens.

they are described as being born differently. According to AvP 2, a Praetorian is a full grown drone (or other 3rd stage xenomorph) that grows old and begins to emit different pheromones that cause the hive to react violently towards it. If the molting Praetorian manages to escape the Hive, it can finish the molting process and return to the Hive to reassert its position. This makes it so only the strongest, most worthy drones can become a protector of the queen.

Praetorians are easily recognized by their crown shaped headcrest, which is very similar in appearance to the Queen's (the only difference being the three rear-facing spires of the crests; the queens' two side spires curving inward toward the straight, middle spire while all three of the praetorians' being more straight).

 and chaos on the Hiveworld. While a drone was morphing to take the previous Mother's place, several deviant, drones, designated as "red drones" by the humans due to their dull, burgundy color, were born that rebelled against the primary hive, and a countering red hive, led by a red Queen Mother, was created. In Aliens: Genocide, massive warfare has broken out between the two subspecies over rule of the planet as the dominant xenomorph species. A fleet of Colonial Marines (financed by the Grant Corporation, Weyland-Yutani's competition in the Aliens novels) were sent on a mission to retrieve the deceased Mother's royal jelly, located in the "black" hive, in order to synthesize a highly addictive drug called Xeno-Zip, a.k.a. Fire (which the government felt was a "highly useful" combat drug). The crew decided to destroy the red Mother's hive to distract the drones of the original nest while the jelly was being extracted. The new Queen Mother was shot after killing a scientist during the extraction.

Rogue Alien

 engineered the Rogue Alien: 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, the engineered Alien King escapes and wreaks havoc until it is killed by a Queen.

In the book of the same name, the Rogue is believed to be more powerful than the Queen, but Dr. Ernst Kleist, the scientist who created the Rogue, is shocked to find the Queen is in fact the superior specimen. While the Rogue is larger and stronger, the Queen's superior speed and intellect enable her to easily dodge the Rogue's brutish attacks while she slowly wears it down and finally slaughters it. Kleist is subsequently killed when he uses a sound cannon (a sound device he designed to [and that did] instantly freeze the movements of xenomorphs) on the Queen until it goes critical, destroying the asteroid-base he is on. The Rogue is seemingly much more aggressive and mercilessly attacks the smaller castes of Aliens. This is illustrated when Professor Kleist finds the crushed corpses of the elite Praetorian guard of the queen. The Rogue's recklessness is shown when it destroys the barrier that separates the Alien sector and the Human sector, thus allowing any Alien drones that escaped the Rogue's notice to pour into the Human sector.

Chrysalis

A very large (around the same size as a Praetorian) Xenomorph with a greyish-green exoskeleton and a hard, tan carapace on its head, back, and forearms. It sometimes moves/attacks by rolling itself along the ground in a ball. It gets its name from the chrysalis that it is seen gestating in when it first appears. The Chrysalis's head can actually extend a short distance from underneath the carapace over its head when biting its prey, in addition to the extension of the inner mouth. More Chrysalis are also seen defending the Queen during the final battle. These have a reddish or blue coloring.

A variation of the Chrysalis appears in the second level of the Konami "Aliens" arcade game, but it looks considerably different and has a different attack pattern.

They are almost identical to normal xenomorphs in ability but have white and yellow pigmentations to their exoskeleton rather than the dark colors usually seen. They were eventually wiped out in a hive war to keep the species of xenomorphs "pure" (being that they weren't naturally created, but were instead clones).

, a Praetorian can evolve 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, and some can even carry 12. Their vulnerability is their weak armor and their frailty against fire, but their greatest advantages are the face-huggers they are carrying. After the carrier is dead the facehuggers riding will scatter everywhere.
Some times Carriers will actually hurl the face huggers it is carrying at its foes.

Carriers are arguably the most valuable tool for expansion of the hive in the game as it allows face huggers to traverse great distances without them needing to consume their own organs to survive whilst they are attached to the Carrier.

The Ravager Xenomorph is possibly one of the largest alien breeds ever created, it is familiar to the appearance of a normal alien except of their large armour-like shoulder bones and dark blue skin. This Xenomorph possesses huge, scythe-like claws that have the ability to instantly decapitate enemies with one swipe. They can slice through a star ship's hull and their powerful armor makes them impervious to all but the most intense assault. Ravagers can also heal themselves over short periods of time. It can be argued that Ravagers are bred to be more geared toward all-out warfare than most breeds of Xenomorphs, as their claws are more of a blade-like appearance rather than merely claws and the fact that Ravagers rely more upon brute force to overpower multiple enemies, whereas most Xenomorphs called upon stealth or numbers to overcome such obstacles. Even more dangerous and brutal about Ravagers is the fact that they make no effort in capturing hosts for breeding, and will, instead, kill and/or destroy potential hosts.

PredAlien

The "PredAlien" is the product of an Alien Facehugger impregnating a Predator
Predator (alien)
The Predator is a fictional extraterrestrial species featured in the Predator science-fiction franchise, characterised by its trophy hunting of other dangerous species for sport, including humans and its fictional counterparts, Aliens....

.
The PredAlien caste has appeared in comic books, video games, and one film, in that order. Appearance and abilities vary between media, with varying degrees of common traits to its host species.

The AvP games have 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 as being light brown with green mottling, similar to the skin-color of the Predators. In the first 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. In other media, it shares more of a resemblance with its host than all other xenomorphs.

In Aliens vs. Predator: Extinction a PredAlien Queen appears in the final Predator mission saying it is "impure" and "an abomination". The PredAlien Queen's head was cut off and set onto a shrine while the rest of the hive was slaughtered by the clan and an Ancient Nuke Carrier destroyed the cave where the hive made base to insure the PredAlien Queen's impure strain would not spread.

Also the predalien-Queen showed different pigmentation and also different features. She was brown and had a predator mouth, and predator hair. She was tougher than the regular alien queens and she didn't have acidic blood.

The beastery/ codex of the game does not say that a Predalien can impregnate hosts.

Empress

The Empress is essentially a larger, and possibly older, version of a Queen, also capable of laying eggs. When there are multiple Queens in an area, they will fight for dominance, the winner becoming the ascendant ruler over the others, and thereby all other Aliens on the planet.

Appears in:
  • Aliens vs. Predator 2

Leech

Though not given a specific name in-game, the leech appeared in Aliens: Extermination and appeared to be a part of the Xenomorph life cycle. Like the game's facehuggers, they would leap at the screen and take damage slowly. Before doing so, they would hang from walls and ceiling until the player got near enough to perform the jump. They would be a product of scientific experimentation, though, as the whole complex is run by xenomorph-studying androids.

Razor Claws

Another large breed with a purple coloration and large, sharp claws on its fingers. It is known for its great speed, making it hard to defeat or even keep up with. It is fond of using that speed to make dashing attacks in which it uses its namesakes to cause massive damage and slice its victims in half. The birth of the Razor Claws was a result of a genetic malfunction in the cocoon process.

Their only weakness appears to be a flashing green light that, when hit, shuts the Xenoborg down.
