Information
Type	Endoparasitoid lifeform

The "Alien" (colloquial: "Xenomorph XX121"; binomial: Internecivus raptus ["murderous thief"]^[1][2][3][4]) is a fictional endoparasitoid extraterrestrial species that is the eponymous antagonist of the Alien film series. The species made its debut in the film Alien (1979), and reappeared in the sequels Aliens (1986), Alien 3 (1992), and Alien Resurrection (1997), as well as the crossover films Alien vs. Predator (2004) and Aliens vs. Predator: Requiem (2007).

The Alien design is credited to Swiss surrealist and artist H. R. Giger, originating in a lithograph titled Necronom IV and refined for the series' first film, Alien. The practical effects for the Alien's head were designed and constructed by Italian special effects designer Carlo Rambaldi. The species' design and life cycle have been extensively augmented, sometimes inconsistently, throughout each film.

Similar creatures of a slightly different designs named the "Deacon" makes a brief appearance in the Ridley Scott film Prometheus (2012). Two species, one being a different but similar creature called a "Neomorph" and the other being a variation of the Xenomorph XX121 species appear in the sequel to Prometheus, Alien: Covenant (2017), which reveals the potential origin of the species.^[5][6] In addition, the Alien appears in various literature and video game spin-offs from the franchises.

Unlike many other extraterrestrial races in science fiction, the Aliens are not sapient "tool-makers"; they lack a technological civilization. They are predatory creatures with no higher goals than the propagation and self-preservation of their species. Like wasps or termites, Aliens are eusocial, with a single fertile queen breeding a caste of warriors, workers, or other specialists strains. The Aliens' biological life cycle involves traumatic implantation of endoparasitoid larvae inside living hosts; these "chestburster" larvae erupt from the host's body after a short incubation period, rapidly mature from juvenile into adulthood within hours, and seek out more hosts for implantation.

Concept and creation

Necronom IV, Giger's 1976 surrealist print that formed the basis for the Alien's design

The script for the 1979 film Alien was initially drafted by Dan O'Bannon and Ronald Shusett. Dan O'Bannon drafted an opening in which the crew of a mining ship are sent to investigate a mysterious message on an alien planet. He eventually settled on the threat being an alien creature; however, he could not conceive of an interesting way for it to get onto the ship. Inspired after waking from a dream, Shusett said, "I have an idea: the monster screws one of them", planting its egg in his body, and then bursting out of his chest. Both realized the idea had never been done before, and it subsequently became the core of the film.^[7] "This is a movie about alien interspecies rape," O'Bannon said in the documentary Alien Evolution. "That's scary because it hits all of our buttons."^[8] O'Bannon felt that the symbolism of "homosexual oral rape" was an effective means of discomforting male viewers.^[9]

Giger's Alien design, inspired by his earlier print Necronom IV, for the film Alien

The title of the film was decided late in the script's development. O'Bannon had quickly dropped the film's original title, Star Beast, but could not think of a name to replace it. "I was running through titles, and they all stank", O'Bannon said in an interview, "when suddenly, that word alien just came out of the typewriter at me. Alien. It's a noun and it's an adjective."^[7] The word alien subsequently became the title of the film and, by extension, the name of the creature itself.

Prior to writing the script to Alien, O'Bannon had been working in France for Chilean cult director Alejandro Jodorowsky's planned adaptation of Frank Herbert's classic science-fiction novel Dune. Also hired for the project was Swiss surrealist artist H. R. Giger. Giger showed O'Bannon his nightmarish, monochromatic artwork, which left O'Bannon deeply disturbed. "I had never seen anything that was quite as horrible and at the same time as beautiful as his work" he remembered later.^[10] The Dune film collapsed, but O'Bannon would remember Giger when Alien was greenlit, and suggested to director Ridley Scott that he be brought on to design the Alien, saying that if he were to design a monster, it would be truly original.^[7]

Carlo Rambaldi, the creator of the mechanical head-effects for the creature, was most famous for designing the title character of the film E.T. the Extra-Terrestrial

After O'Bannon handed him a copy of Giger's book Necronomicon, Scott immediately saw the potential for Giger's designs, and chose Necronom IV, a print Giger completed in 1976, as the basis for the Alien's design, citing its beauty and strong sexual overtones. That the creature could just as easily have been male or female was also a strong factor in the decision to use it. "It could just as easily fuck you before it killed you," said line producer Ivor Powell, "[which] made it all the more disconcerting."^[8]Fox Studios were initially wary of allowing Giger onto the project, saying that his works would be too disturbing for audiences, but eventually relented. Giger initially offered to completely design the Alien from scratch, but Scott mandated that he base his work on Necronom IV, saying that to start over from the beginning would be too time-consuming. Giger signed on to design the adult, egg and chestburster forms, but ultimately also designed the alien planetoid LV-426 and the Space Jockey alien vessel.^[7]

Giger conceived the Alien as being vaguely human but a human in full armor, protected from all outside forces. He mandated that the creature have no eyes, because he felt that it made them much more frightening if you could not tell they were looking at you.^[8] Giger also gave the Alien's mouth a second inner set of pharyngeal jaws located at the tip of a long, tongue-like proboscis which could extend rapidly for use as a weapon. His design for the creature was heavily influenced by an aesthetic he had created and termed biomechanical, a fusion of the organic and the mechanic.^[8] His mock-up of the Alien was created using parts from an old Rolls Royce car, rib bones and the vertebrae from a snake, molded with plasticine. The Alien's animatronic head, which contained 900 moving parts, was designed and constructed by special effects designer Carlo Rambaldi.^[7] Giger and Rambaldi together would win the 1980 Academy Award for Visual Effects for their design of the Alien.

H. R. Giger, who designed and worked on the Alien and its accompanying elements

Scott decided on the man-in-suit approach for creating the creature onscreen. Initially circus performers were tried, then multiple actors together in the same costume, but neither proved scary. Deciding that the creature would be scarier the closer it appeared to a human, Scott decided that a single, very tall, very thin man be used. Scott was inspired by a photograph of Leni Riefenstahl standing next to a 6'4" (1.93 m) Nuba man.^[11] The casting director found 6'10" (2.08 m), rail-thin graphic designer Bolaji Badejo in a local pub. Badejo went to tai chi and mime classes to learn how to slow down his movements.^[7]

Giger's design for the Alien evoked many contradictory sexual images. As critic Ximena Gallardo notes, the creature's combination of sexually evocative physical and behavioral characteristics creates "a nightmare vision of sex and death. It subdues and opens the male body to make it pregnant, and then explodes it in birth. In its adult form, the alien strikes its victims with a rigid phallic tongue that breaks through skin and bone. More than a phallus, however, the retractable tongue has its own set of snapping, metallic teeth that connects it to the castrating vagina dentata."^[9]

Name

This creature is named Xenomorph XX121, and has been referred to most often onscreen, and in the credits of each film, simply as the Alien. It was called an alien, and an organism, in the first film. It has also been referred to as a creature,^[3] a serpent,^[12] a beast,^[4] a dragon,^[4] a monster,^[3] a nasty, or simply, a thing.^[13] The term xenomorph (lit. "alien form"—from Greek xeno-, which translates as either "other" or "strange", and -morph, which denotes shape) was first used by the character Lieutenant Gorman in Aliens^[3] with reference to generic extraterrestrial life. The term was erroneously assumed by some fans^[14] to refer specifically to this creature, and the word was used by the producers of some merchandise.^[15] The species' binomial names are given in Latin as either Internecivus raptus (meant as "murderous thief") in the Alien Quadrilogy DVD or Lingua foeda acheronsis (meant as "foul tongue from Acheron")^{[NB 1]} in some comic books.^[16] The main Alien from Alien vs. Predator is listed in the credits as "Grid", after a grid-like wound received during the film from a Predator's razor net.^[12]Alien: Covenant actually credits the Alien as Xenomorph, while also listing a different variety of the creature as the Neomorph.^[5][6] In The Weyland-Yutani Report, the Alien was specifically referred to as "Xenomorph XX121".^[1]

Characteristics

As the film series has progressed, the creature's design has been modified in many ways, including differing numbers of fingers and limb joints, and variations in the design of the Alien's head.

Appearance

Giger's Alien, as portrayed by Bolaji Badejo in Ridley Scott's 1979 film Alien

When standing upright, the Aliens are bipedal in form, though depending on their host species, they will either adopt a more hunched stance, or remain quadrupedal when walking or sprinting. Their overall stance and general behavior is a result of the mixture of the DNA of the embryo and the host. They have a skeletal, biomechanical appearance and are usually colored in muted shades of black, gray or bronze. Their body heat matches the ambient temperature of the environment in which they are found, so they do not radiate heat, making them indistinguishable from their surroundings through thermal imaging.^[3][12] In most of the films, adult Aliens are capable of running and crawling along ceilings and walls.^[3][4] They have great physical strength, having been shown to be capable of breaking through welded steel doors in numbers.^[3]

Aliens have segmented, blade-tipped tails. The sharp tip was initially a small, scorpion-like barb,^[13] but from Aliens onwards the blade design increased in size and changed in appearance to more closely resemble a slashing weapon.^[3][12] From Alien Resurrection onwards, the tails have a flat ridge of spines at the base of the blade. This was introduced to help them swim convincingly,^[17] and was left intact in the subsequent crossovers. The original shooting script for Aliens and the novelization both featured a scene in which Lieutenant Gorman is "stung" by the barb tail and rendered unconscious; in the final cut of the movie, Gorman is knocked out by falling crates. As a weapon, the strength of the tail is very effective, having been shown to be strong enough to impale and lift a Predator with seemingly little effort.

They have elongated, cylindrical skulls, but possess no visible eyes, though in the original Alien film, the top of the creature's head was translucent, with empty, human-looking eye sockets within. In the novelization of Alien, the character Ash speculates that the Xenomorphs "see" by way of electrical impulse, similar to a shark's lateral line. This method is illustrated in the original Alien vs Predator PC game, and reused for the "Predalien" 28 years later. There is a cyclopean species of Xenomorph, which is the creature in its original form, it has a single large eye under its natural silicon / keratin forehead which can give the creature 180 degree vision. The Aliens' inner set of jaws are powerful enough to smash through bone and metal.^[12] How the creatures see is uncertain; in Alien 3, a spherical lens was used to illustrate the Alien's point of view, so, when the film was projected anamorphically, the image exhibited severe distortion. In the novelization of the movie Alien, the creature is held mesmerized by a spinning green light for several minutes.

In Aliens, the adult creatures have a more textured head rather than a smooth carapace. In the commentary for Aliens, it was speculated that this was part of the maturation of the creatures, as they had been alive far longer than the original Alien, although James Cameron stated that he simply left the carapace off because he liked them better that way.^[3] The smooth design of the carapace would be used again in Alien 3 and Alien: Resurrection, although made narrower with a longer muzzle and more prominent chin. This design would be kept in Alien versus Predator,^[18] and abandoned in Aliens vs. Predator: Requiem in favor of the ribbed design.

Throughout their appearances, human-spawned Aliens have been shown to have different numbers of fingers. In Alien, the creature has webbed, six-fingered hands. In Aliens, the number of fingers is reduced to three (two "paired" and a single, opposable thumb), and they are shown to be much longer and more skeletal. In Alien: Resurrection, the number of digits is increased to four, with two long middle fingers and a pair of thumbs. This design is kept in the Alien vs. Predator films, though the hands were made bulkier in order to make the Aliens seem more formidable against the Predators.^[19]

Aliens have been alternatively portrayed as both plantigrade and digitigrade organisms, usually relative to their host. Human-spawned Aliens were usually portrayed as having humanoid hind limbs, while in Alien 3, the featured Alien sported double-jointed legs due to its quadrupedal host. This characteristic would be continued in Alien: Resurrection for the human-spawned Aliens. Tom Woodruff, who had previously played the "dog-alien" in Alien 3, described the human-spawned Aliens in Resurrection as feeling more like a dog than the previous creature, despite having been born from human hosts.^[20] The human-spawned Alien warriors would revert to a plantigrade posture in Alien vs. Predator.

Physiology

Alien blood is an extremely potent acid and is capable of corroding almost any substance on contact with alarming speed. It is dull yellow in color, and appears to be pressurized inside the body so that it spurts out with great force when the creature is wounded. Ron Cobb suggested the idea of the Alien having acid blood as a plausible means to make the creature "unkillable"; if one were to use traditional firearms or explosives to attack it, its blood would eat through the hull of the ship.^[21] The Alien novelization suggests that, at least at the "facehugger" stage, the acid is not blood but a fluid maintained under pressure between a double layer of skin.^[22] In the Aliens vs. Predator: Requiem documentary: "Science of the Alien", it is hypothesized that the Aliens' acid blood could be some type of "hydrosulphuric acid" compound due to its corrosiveness and the conspicuously toxic effects on living human tissue. The documentary also speculates that Aliens are immune to their own acidic and toxic liquids due to an endobiological build-up, similar to the human stomach's ability to protect itself from its own digestive fluids. The documentary takes this hypothesis one step further and speculates that the Alien organisms' protection system against its own toxic hydrosulphuric acid is basically a bio-organically produced Teflon insulation.^[23] In the original Alien, the facehugger is shown to be able to "spit" acid, dissolving the faceplate of Kane's helmet and allowing the creature immediate access inside. This ability is also exhibited by adult Aliens in Alien 3 and Alien: Resurrection; much like a spitting cobra, they use it to blind and immobilize their victims.^[4][24]

Aliens can produce a thick, strong resin that they use to build their hives and to cocoon their victims, and they can use the walls of their hives as camouflage.^[25] Aliens also salivate heavily in the form of a sticky, clear slime; while not a toxic substance in and of itself, it is common for the Alien films to use it as a suspense-building device, wherein a character will notice the falling saliva before noticing its source lying in wait above them.^[25]

Intelligence

During various events in Aliens on the LV-426 colony: Hadley's Hope, in Alien Resurrection on the USM Auriga and in the crossover movie Alien vs Predator, the species displayed observational learning and problem solving skills,^[3][24] and in the former two cases the Aliens learnt how to operate machinery at a very basic level. On LV-426, they were able to cut power in a section of the complex to gain access to the humans, and the Alien Queen learns to board an elevator by observing Ripley and Newt escaping in the one beside it. The novelization of the film notes that the queen establishing her "nest" at the base's main power plant could have been chosen either for the feral, animal reason of the warmth that it would provide or for the rational reason of selecting a location where any attackers would be unable to destroy her without destroying the entire facility. In the director's commentary for Aliens, James Cameron noted that the creatures in Aliens had been alive for far longer than the Alien in the original, and had more time to learn about their environment.^[26] On the USM Auriga in Alien Resurrection, the Aliens kill one of their own, using its blood to melt through their enclosure and escape; in Alien vs. Predator, they use a similar strategy to free the queen from her chains. An Alien also uses acid spurting from its severed tail as an improvised weapon, indicating they are fully aware of the effects of their acid blood.

Life cycle

Aliens are eusocial life-forms with a caste system ruled over by a queen.^[3][12][24] Their life cycle comprises several distinct stages: they begin their lives as an egg, which hatches a parasitoid larval form known as a facehugger, which then attaches itself to a living host by, as its name suggests, latching onto its face. In the Alien 3 novelization, Ripley commented that this parasitoid would probably be able to use a host as small as a cat, or as large as an elephant.

The facehugger then "impregnates" the host with an embryo, known as a "chestburster",^{[NB 2]} which, after a period of gestation, erupts violently from the host's chest, resulting in the death of the host.

The chestburster then matures to an adult phase, shedding its skin and replacing its cells with polarized silicon. Due to horizontal gene transfer during the gestation period, the Alien also takes on some of the basic physical attributes of the host from which it was born, allowing the individual alien to adapt to the host's environment.

The adult phase of the Alien is known by various different names. The adult Aliens have been referred to as "drones", "warriors", "workers", and sometimes "soldiers", similar to the way ants have been defined. The names of the adult phase have also been used to name different types of adult phases of the Alien in numerous sources, including video games, comic books, novels, and the films, but only in the commentaries by the team who created the films. No official name has been given to the adult stage of the Alien in the films themselves.

Queen

Ripley's first encounter with a queen

Queen Aliens are significantly larger and stronger than the normal adults, being approximately 4.5 metres (15 ft) tall.^[27] Their body structure differs also, having two pairs of arms, one large and one small. The queen's head is larger than those of other adult Aliens, and is protected by a large, flat crest, like a crown, which varies from queen to queen. Unlike other aliens, the queen's external mouth is separately segmented from the rest of her head, allowing her to turn her mouth left and right almost to the point where it is facing perpendicular to the direction of the rest of her head. In the second film, Aliens, unlike other adults and queens, the queen had high-heel protrusions from her feet.

Egg-laying Alien queens possess an immense ovipositor attached to their lower torso, similar to a queen termite's. Unlike insect queens, there appears to be no need for an Alien queen's eggs to be fertilized.^[12][24] When attached to her ovipositor, the queen is supported by a "biomechanical throne"^[28] that consists of a lattice of struts resembling massive insect legs.

In the original cut of Alien, the Alien possessed a complete lifecycle, with the still-living bodies of its victims converted into eggs. However, the scene showing the crew converted into eggs was cut for reasons of pacing, leaving the ultimate origin of the eggs obscure. This allowed Aliens director James Cameron to introduce a concept he had initially conceived for a spec script called Mother,^[26] a massive mother Alien Queen which laid eggs and formed the basis for the Aliens' life cycle. Cameron conceived the Queen as a monstrous analogue to Ripley's own maternal role in the film.^[26] In that vein, some critics have compared it to Grendel's mother.^[29][30]

The queen was designed by Cameron in collaboration with special effects artist Stan Winston, based upon an initial painting Cameron had done at the start of the project. The Winston Studio created a test foam core queen before constructing the full hydraulic puppet which was used for most of the scenes involving the large Alien. Two people were inside working the twin sets of arms, and puppeteers off-screen worked its jaws and head. 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. An adult queen was to reappear in Alien Resurrection. The original mechanical head previously used in Aliens was provided by Bob Burns and was an altered design. It was repainted with a blend of green and brown, giving it a shimmering, insect-like quality. This color concept would be abandoned in Alien vs. Predator in favour of the original black color scheme.^[19]

In the climax of Alien vs. Predator, the queen's basic design was altered to make her more "streamlined" in appearance and her overall size was increased to 6 meters (20 feet) tall. Other changes include the removal of the "high-heel" protrusions on her legs, including additional spines on her head and making her waist thinner because there was no need for puppeteers inside her chest. The animatronic queen had 47 points of hydraulic motion.^[19]

Aliens vs. Predator: Requiem (2007) introduced a younger form of the full-grown queen, albeit with traits inherited from its Predator host. Recalling the facehugger's method of embryo implantation, the Predalien uses its inner mouth to directly deposit multiple chestburster embryos into pregnant female hosts, also using its mandibles to latch on the faces of said hosts, completely bypassing the need for facehuggers.^[31] This is explained by the Brothers Strause as a means of quickly building an army of Aliens before the young queen evolves into its sedentary, egg-laying state.^[32]

Egg

The eggs laid by the queen are ellipsoidal, leathery objects between 0.5 and 1 meters (two and three feet) high with a four-lobed opening at the top. The eggs can remain in a stasis mode for years, possibly indefinitely, until nearby movement is detected. 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 obvious vaginal appearance, complete with an "inner and outer vulva".^[33] 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".^[33] The interior of the original egg was composed of "Nottingham lace" (caul fat), 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.^[7] Initially, the egg remained totally stationary except for the hydraulic movement of the lobes; however, by Alien: Resurrection, the entire egg was made to ripple as it opened. In Alien, the Director's Cut, an additional scene shows still living crew members being cocooned into new eggs, either morphing into a new embryo, or acting as a food source for the face-hugger inside the egg.

Facehugger

The facehugger seen in Alien

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 arthropods such as arachnids and horseshoe crabs.

The facehugger is a parasitoid; 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 administers a cynose-based paralytic in order to render it unconscious and immobile.^[34][1] During a successful attachment, the facehugger will insert a proboscis down the host's throat, while simultaneously implanting an embryo. The host is kept alive, and the creature breathes for the host.^[13] Attempts to remove facehuggers generally prove fatal,^[3] as the parasitoid will respond by tightening its tail around the host's neck, and its acidic blood prevents it from being cut away. In addition, its grip on the host's head is strong enough to tear the host's face off if it is forcibly removed.^[13]

Once the Alien embryo is implanted, the facehugger will remain attached until the implant is secure, which can take anywhere from less than a minute to sixteen hours, once this happens the parasite detaches, crawls away and dies.^[1] The victim awakens with no awareness of the implantation, believing themselves to have been asleep, and appears to have a normal, healthy bodily function.

According to AVPR: Science of the Xenomorph, a behind-the-scenes documentary on Aliens vs. Predator: Requiem, it is theorized that facehuggers may implant a viral agent that "commands" the host's cells to grow the chestburster, as opposed to an implanted embryo.^[35] This would explain how the resulting alien is able to adopt the characteristics of its host.

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.^[36] 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 should 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.^[37]Dan O'Bannon initially conceived the facehugger as somewhat resembling an octopus, possessing tentacles. However, when he received H. R. Giger's designs, which substituted tentacles with fingerlike digits, he found Giger's design concept to be superior. Since no one was available at the time, O'Bannon decided to design the facehugger prop himself. The technical elements of the musculature and bone were added by Ron Cobb. Giger's initial design for the smaller facehugger had the fingers facing forward, but O'Bannon's redesign shifted the legs to the side. When the foam rubber sculpture of the facehugger was produced, O'Bannon asked that it should remain unpainted, believing the rubber, which resembled human skin, was more plausible.^[38]

In Aliens, the facehuggers were redesigned by Stan Winston so that they would be capable of movement. Unlike the creatures in the first film, the creatures would take a much more active role in impregnating their victims. When Ripley throws one off her, the facehugger was now capable of scuttling across the floor and leaping at its prey, wrapping its tail around the victim's throat. The facehugger is also shown to be capable of independently surviving outside of its egg. Due to the film's budget, only two fully working facehuggers were built.

In Alien 3, another addition, a "super-facehugger" that would carry the embryo of the queen Alien, was planned, but ultimately dropped.^[39] The super-facehugger is briefly glimpsed in the Assembly cut of Alien 3, but not identified as such.^[39][40] It made a brief appearance in the canonical Alien book called Alien: Sea of Sorrows, set a while after the events of Alien Resurrection, about the grandson of Ripley Clone 8, Ellen Ripley's clone.

Chestburster

The chestburster from the original film

After implantation, facehuggers die and the embryo's host wakes up afterwards showing no considerable outward negative symptoms, and a degree of amnesia regarding events at the time of implantation. Symptoms build acutely after detachment of the facehugger, the most common being sore throat, slight nausea, increased congestion, and moderate to extreme hunger.^[13] In later stages where the incubation period is extended in preparation of a queen birth, symptoms will include a shortness of breath, exhaustion, and hemorrhaging (detectable through biological scanners and present in nosebleeds or other seemingly random bleeding incidents), as well as chest pains inflicted either in lack of chest space due to the chestburster's presence, or even premature attempts to escape the host. The incubating embryo takes on some of the host's DNA or traits, such as bipedalism, quadrupedalism,^[4] possessing the mandibles of a Predator,^[41] and other structural changes. According to Weyland-Yutani scientists in Aliens: Colonial Marines, the chestburster will draw nutrients from the host's body in order to develop a placenta as it grows, attaching itself to several major organs in the process. The placenta has cancerous qualities, such that even if the embryo were removed surgically, the placenta would simply cause the affected organs to shut down, resulting in death. 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 and fatally ripping open the chest of the host. There is no on-screen explanation of the reasons for the different incubation times. Fully-grown aliens may avoid harming species acting as hosts for un-emerged chestbursters, though this may only be in the case of a queen embryo.

The emerging alien varies in size from a guinea pig to a large dog, depending on the size and species of the host, and its appearance and adaptive characteristics are also determined by the host. Typically, its first instinct upon emerging is to flee and hide until full maturation.

The chestburster was designed by Alien director Ridley Scott and constructed by special effects artist Roger Dicken.^[9] Giger had produced a model of a chestburster that resembled a "degenerate plucked turkey"^{[42][clarification needed]} and was far too large to fit inside a ribcage. Much to Giger's dismay, his model reduced the production team to fits of laughter on sight. Scott drafted a series of alternative designs for the chestburster based on the philosophy of working "back [from the adult] to the child" and ultimately produced "something phallic".^[8] 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.^[43] This concept would be abandoned in Alien: Resurrection, but return in Alien: Covenant.

When a chestburster erupts from the body of its host, it is less than 30 centimetres (0.98 ft) 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.^{[NB 3]} The chestburster is shown to have molted before reaching maturity.^[13] In Aliens vs. Predator: Requiem, Alien warriors are shown who are still growing, showing shedding skin. In the unrated cut, the Predalien is shown wiping off its final molted skin at the film's start.

Alternative forms

Aliens take on various forms depending on the characteristics of their hosts. Most of the Aliens seen to date have been human-spawned, but a number of Aliens born from other hosts have also been seen. Some of these are also a different variants or species altogether such the Neomorph and Deacon.

"Dragon"

The quadrupedal Alien variant from Alien 3

The "Dog Alien" or "Ox Alien", (also known as "Runner Alien" in the expanded universe stories) and referred to in-film as "Dragon", was introduced in Alien 3. The creature itself shares the same basic physical configuration and instincts as the other Aliens shown in the previous films, although there are several differences due to the host it was spawned from (a dog in the theatrical cut, an ox in the DVD assembly cut). The Dog Alien in its Chestburster form is a miniature version of the adult, unlike the larval human- and Predator-spawned chestbursters. The adult is primarily quadrupedal, has digitigrade hind legs and lacks the dorsal tubes of the human-spawned variety. The only differences behavior-wise was that this Alien behaved more like a dog or another quadrupedal animal that generally is prone to using its mouth instead of its front legs as its primary weapon to attack and maul its victims with its teeth. This Alien, even when actively provoked, would not attack or kill Ripley, due to the Queen growing inside her. This, however, changed towards the movie's climax, at which point the monster, after surviving a torrent of molten lead, burst from the liquid and went into a rampage, pursuing Ripley and presumably attempting to kill her until she destroyed it by showering it with freezing water, causing it to explode from thermal shock.

Concept and credit controversy

Originally, H. R. Giger was approached on July 28, 1990, by David Fincher and Tim Zinnemann, and was asked to redesign his own creations for Alien 3. Giger's new designs included an aquatic face-hugger and a four-legged version of the adult Alien. Giger said in an interview "I had special ideas to make it more interesting. I designed a new creature, which was much more elegant and beastly, compared to my original. It was a four-legged Alien, more like a lethal feline – a panther or something. It had a kind of skin that was built up from other creatures – much like a symbiosis." However, when Tom Woodruff and Alec Gillis of Amalgamated Dynamics told Giger that they had their own design, Giger expressed himself as "very upset" and that the creature he had especially designed was his "baby". Even after the production severed contact, Giger continued to fax suggestions to Fincher, and made full-scale drawings and a sculpt of the Alien, all of which were rejected.

David Fincher neglected to inform me that Woodruff and Gillis were also contracted to take care of the redesign of the Alien – I found out much later... I thought I had the job and that Woodruff and Gillis would work from my plans. On their side, they were convinced that it was their job and accepted my 'suggestions' with pleasure. They believed that all my effort was based on a huge love for the matter, because I worked hard even after my contract was over.

Giger would later be angered by the end credits of the released film presenting him as merely the creator of the original creature, and the fact that ADI personnel gave a series of interviews that minimized Giger's contribution. Fox eventually reimbursed Giger, but only after he refused to be interviewed for their behind-the-scenes documentary of Alien 3.

However, Giger would comment that he thought the resulting film was "okay" and that the Alien was "better than in the second film".^[44]

Newborn

The "Newborn", seen here with Ripley in Alien Resurrection

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 perversion of a human womb, and as a result it ceases to lay eggs and gives birth to a humanoid mutant hybrid. Physically, the human-Alien Newborn is very different from other alien young, being larger, with pale, translucent skin, a skull-shaped face with eyes, a human tongue and a complete absence of a tail. The Newborn fails to bond with its Alien Queen mother, killing it, and imprinting on the Ripley clone instead.

The Newborn creature was originally scripted by Joss Whedon as being an eyeless, ivory-white quadruped with red veins running along the sides of its head. It had an inner jaw, with the addition of a pair of pincers on the sides of its head. These pincers would have been used to immobilize its prey as it drained it of blood through the inner jaw. The creature was originally going to rival the Queen in size, but Jean-Pierre Jeunet asked ADI to make the human-Alien hybrid, known as the Newborn, more human than Alien. The Newborn's eyes and nose were added to improve its expressions to make it a character, rather than just a "killing machine", and give it depth as a human like creature.

Predalien

The Predalien as depicted in Aliens vs. Predator: Requiem

This variation is the result of a facehugger impregnating a Predator. The "Predalien" was first depicted in a painting by Dave Dorman, and subsequently featured in the Aliens versus Predator comics and games. A Predalien chestburster debuts in the final scene of Alien vs. Predator, but it is not seen until Aliens vs. Predator: Requiem, as an adult Predalien makes the first film appearance.

The Predalien shares many characteristics with its hosts, such as long hair-like appendages, mandibles, skin color, and similar vocalizations. It is a large, bulky creature, and possesses physical strength greater than that of human-spawned Aliens. 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.^[45]

Deacon

The dark-blue Deacon is a different species that makes an appearance in Prometheus, though it clearly shares traits similar to the Xenomorph, including a similar life-cycle. The Deacon is the result of a Trilobite, which is a large facehugger-like creature, attacking and impregnating an Engineer. After some time, it will burst out of its host, with the notable difference that it is "born" almost fully developed in regards to its limbs and structure. Its fate is unknown, though the tie-in comic book Prometheus: Fire and Stone, also set on LV-223, features a mutated mountain, with acidic veins which are implied to be the heavily mutated Deacon.^[46]

Neomorph

The pale-white Neomorph is featured in Alien: Covenant.^[6] It was created through exposure to spores found growing on the Engineer homeworld. The embryronic Neomorph then gestates inside the host, until it bursts out of its host's back, throat, or possibly other areas, using mostly its head, which is sharp and pointed, similar to the Deacon. Like the Xenomorph, the Neomorph has a tail, which is strong enough to tear off a human jaw. The Neomorph is a less weaponized version of the Xenomorph and lacks the facial features and biomechanical traits of the latter. The Neomorph is far more feral than the traditional Xenomorph; they are voracious predators, often eating the corpses of their victims. Unlike the Xenomorph, the Neomorph appears to lack a hive structure, since they propagate through mutated animal life.^[5]

Cultural impact

In the years since the release of Alien, the Alien has become one of the world's most recognized movie monsters and a popular-cultural icon. In 2003, the Alien was voted as the 14th most memorable screen villain by the American Film Institute.^[47]Blondie co-founder Chris Stein, who was a friend of Giger, pondered in an interview:

I'd like to see someone even vaguely compile how many versions of the Alien are floating around the world in models and stuff; there must be close to 100,000–little toys, things. All the Japanese horror comics just plunder his style.^[48]

Examples of Alien-inspired works include the classic video games Contra^[49] and Metroid.^[50] The Aliens (both grown-up versions and facehuggers) also appear in the second-last stage of Turrican II, and as a boss figure in Mega Turrican.

In the classic parody film Spaceballs, in the final sequence, a Chestbuster is born in a space restaurant and starts dancing and singing, while the 2009 film Planet 51 features small dog-like Xenomorphs with acid urine.

Heinrich, the final boss in the 2001 comedic video game Conker's Bad Fur Day (and its 2005 remake Conker: Live & Reloaded), is a parody of the Alien queen as it appeared in Aliens. Heinrich not only looks very similar to the queen in design, but the reference is further alluded when Conker uses a yellow, mechanical exoskeleton to defeat it, as well as using the line, "Get away from her, you bitch!" as Heinrich looked down upon Berri's body, which is a direct reference to Ellen Ripley battling the queen during the film's final act.

The Aliens have appeared in many crossovers (including a large number of intercompany crossovers) in comic books and other media such as novels, toys, and video games. The largest of these crossovers is the Alien vs. Predator franchise, in which the Aliens battle the Predators. This was an idea that came to comic book artist Chris Warner in early 1989. He and other people at Dark Horse Comics were trying to come up with a good character combo for a new comics series. Dark Horse had been publishing Aliens comic book under license from 20th Century Fox since 1987. In 1990, the first depiction of the idea in film appeared in Predator 2, when an Alien skull, sculpted by Kevin Hudson,^[43] appeared as one of the trophies in the Predator spacecraft.

In the 1995 film Toy Story, one of the games at Pizza Planet, Whack-a-Alien features aliens similar to the Chestbursters.

Because Dark Horse possessed the rights to the franchise in comics, it has been able to feature likenesses of the alien in its other licensed comic books. For example, it did this in a mini-issue of Buffy the Vampire Slayer Season Nine which was billed in the media as an Alien crossover and an Animaniacs episode also featured it. A variation of the alien appears in the Regular Show episode Terror Tales of the Park VI in the "Alien Roommate" segment. A new variation of an Alien is featured as a guest character in the 2015 fighting game Mortal Kombat X, opposite the Predator. This version uses retractable blades in its arms, similar to Mortal Kombat's Tarkatan species, due to having strains of Tarkatan's DNA.^[51]

A variant of the Xenomorph Facehuggers makes a guest appearance in the Japanese light novel franchise Gate: Jieitai Kano Chi nite, Kaku Tatakaeri.^[52][53]

Giger's Alien was iconic enough to have an audio-animatronic version of it appear in The Great Movie Ride at Disney's Hollywood Studios at Walt Disney World. The Alien appeared with the attraction's opening in 1989 until the rides closure in 2017.^[54][55] An Alien-based attraction at the Magic Kingdom entered early development stages before being reworked into ExtraTERRORestrial Alien Encounter.^{[citation needed]} The Alien has a brief cameo in an episode of Zig and Sharko.^[56]
