The Xenomorph (also known as a Xenomorph XX121, Internecivus raptus, Plagiarus praepotens, or simply the alien or the creature<a href="#cite_note-1">[a]</a>)<a href="#cite_note-WYreport-2">[1]</a><a href="#cite_note-3">[2]</a><a href="#cite_note-A2-4">[3]</a><a href="#cite_note-A3-5">[4]</a> is a fictional <a href="Parasitoid" title="Parasitoid">endoparasitoid</a> <a href="Extraterrestrials_in_fiction" title="Extraterrestrials in fiction">extraterrestrial</a> <a href="Species" title="Species">species</a> that serves as the main <a href="Antagonist" title="Antagonist">antagonist</a> of the <a href="Alien_(franchise)" title="Alien (franchise)">Alien</a> and <a href="Alien_vs._Predator" title="Alien vs. Predator">Alien vs. Predator</a> franchises.

The species made its debut in the film <a href="Alien_(film)" title="Alien (film)">Alien</a> (1979) and reappeared in the sequels <a href="Aliens_(film)" title="Aliens (film)">Aliens</a> (1986), <a href="Alien_3" title="Alien 3">Alien 3</a> (1992), <a href="Alien_Resurrection" title="Alien Resurrection">Alien Resurrection</a> (1997), and <a href="Alien%3A_Romulus" title="Alien: Romulus">Alien: Romulus</a> (2024). The species returns in the prequel series, first with a predecessor in <a href="Prometheus_(2012_film)" title="Prometheus (2012 film)">Prometheus</a> (2012) and a further evolved form in <a href="Alien%3A_Covenant" title="Alien: Covenant">Alien: Covenant</a> (2017),<a href="#cite_note-6">[5]</a> and the 2019 short films Alien: Containment, Specimen, Night Shift, Ore, <a href="Alien%3A_Harvest" class="mw-redirect" title="Alien: Harvest">Harvest</a>, and <a href="Alien%3A_Alone" class="mw-redirect" title="Alien: Alone">Alone</a>. It also featured in the <a href="Alien_vs._Predator" title="Alien vs. Predator">crossover</a> films <a href="Alien_vs._Predator_(film)" title="Alien vs. Predator (film)">Alien vs. Predator</a> (2004) and <a href="Aliens_vs._Predator%3A_Requiem" title="Aliens vs. Predator: Requiem">Aliens vs. Predator: Requiem</a> (2007), with the skull and tail of one of the creatures respectively appearing briefly in <a href="Predator_2" title="Predator 2">Predator 2</a> (1990), <a href="Predator%3A_Concrete_Jungle" title="Predator: Concrete Jungle">Predator: Concrete Jungle</a> (2005), <a href="Predators_(film)" title="Predators (film)">Predators</a> (2010), and <a href="The_Predator_(film)" title="The Predator (film)">The Predator</a> (2018), as a protagonist (named 6) in the video game <a href="Aliens_vs._Predator_(2010_video_game)" title="Aliens vs. Predator (2010 video game)">Aliens vs. Predator</a> (2010), and will return in the upcoming <a href="FX_(international)" title="FX (international)">FX</a> television series <a href="Alien%3A_Earth" title="Alien: Earth">Alien: Earth</a> (2025). In addition, the xenomorph appears in various literature and video game spin-offs from the franchises.

The xenomorph's design is credited to <a href="Swiss_(nationality)" class="mw-redirect" title="Swiss (nationality)">Swiss</a> surrealist and artist <a href="H._R._Giger" title="H. R. Giger">H. R. Giger</a>, originating in a <a href="Lithograph" class="mw-redirect" title="Lithograph">lithograph</a> titled Necronom IV and refined for the series's first film, Alien. The practical effects for the xenomorph's head were designed and constructed by <a href="Italian_people" class="mw-redirect" title="Italian people">Italian</a> special effects designer <a href="Carlo_Rambaldi" title="Carlo Rambaldi">Carlo Rambaldi</a>. Species design and life cycle have been extensively augmented, sometimes inconsistently, throughout each film.

Unlike many other extraterrestrial races in film and television science fiction (such as the <a href="Dalek" title="Dalek">Daleks</a> and <a href="Cyberman" title="Cyberman">Cybermen</a> in <a href="Doctor_Who" title="Doctor Who">Doctor Who</a>, or the <a href="Klingon" title="Klingon">Klingons</a> and <a href="Borg" title="Borg">Borg</a> in <a href="Star_Trek" title="Star Trek">Star Trek</a>), the xenomorphs are not <a href="Sapience" class="mw-redirect" title="Sapience">sapient</a> toolmakers — they lack a technological civilization of any kind, and are instead primal, <a href="Predation" title="Predation">predatory</a> creatures with no higher goal than the preservation and propagation of their own species by any means necessary, up to and including the elimination of other lifeforms that may pose a threat to their existence. Like <a href="Wasp" title="Wasp">wasps</a> or <a href="Termite" title="Termite">termites</a>, xenomorphs are <a href="Eusociality" title="Eusociality">eusocial</a>, with a single fertile <a href="#Queen">queen</a> breeding a caste of warriors, workers, or other specialist strains. The xenomorphs' <a href="Biological_life_cycle" title="Biological life cycle">biological life cycle</a> involves traumatic implantation of <a href="Endoparasitoid" class="mw-redirect" title="Endoparasitoid">endoparasitoid</a> <a href="Larvae" class="mw-redirect" title="Larvae">larvae</a> inside living hosts; these "chestburster" larvae erupt from the host's body after a short incubation period, mature into adulthood within hours, and seek out more hosts for implantation.

<div class="mw-heading mw-heading2"><h2 id="Concept_and_creation">Concept and creation</h2></div>

The script for the 1979 film <a href="Alien_(film)" title="Alien (film)">Alien</a> was initially drafted by <a href="Dan_O'Bannon" title="Dan O'Bannon">Dan O'Bannon</a> and <a href="Ronald_Shusett" title="Ronald Shusett">Ronald Shusett</a>. Dan O'Bannon drafted an opening in which the crew of a mining ship is 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.<a href="#cite_note-doc-7">[6]</a> "This is a movie about alien interspecies <a href="Rape" title="Rape">rape</a>", O'Bannon said in the documentary Alien Evolution. "That's scary because it hits all of our buttons."<a href="#cite_note-burster-8">[7]</a> O'Bannon felt that the symbolism of "homosexual oral rape" was an effective means of discomforting male viewers.<a href="#cite_note-9">[8]</a>

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."<a href="#cite_note-doc-7">[6]</a> 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 <a href="Alejandro_Jodorowsky" title="Alejandro Jodorowsky">Alejandro Jodorowsky</a>'s <a href="Alejandro_Jodorowsky#Dune_and_Tusk_(1975–1980)" title="Alejandro Jodorowsky">planned adaptation</a> of <a href="Frank_Herbert" title="Frank Herbert">Frank Herbert</a>'s classic science-fiction novel <a href="Dune_(novel)" title="Dune (novel)">Dune</a>. Also hired for the project was Swiss <a href="Surrealist" class="mw-redirect" title="Surrealist">surrealist</a> artist <a href="H._R._Giger" title="H. R. Giger">H. R. Giger</a>. 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.<a href="#cite_note-10">[9]</a> The Dune film collapsed, but O'Bannon would remember Giger when Alien was greenlit, and suggested to director <a href="Ridley_Scott" title="Ridley Scott">Ridley Scott</a> that he be brought on to design the Alien, saying that if he were to design a monster, it would be truly original.<a href="#cite_note-doc-7">[6]</a>

After O'Bannon handed him a copy of Giger's book <a href="Necronomicon_(Giger_book)" title="Necronomicon (Giger book)">Necronomicon</a>, 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."<a href="#cite_note-burster-8">[7]</a> <a href="20th_Century_Fox" class="mw-redirect" title="20th Century Fox">20th Century Fox</a> was 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 initially 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.<a href="#cite_note-doc-7">[6]</a>

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 one could not tell they were looking at them.<a href="#cite_note-burster-8">[7]</a> Giger also gave the Alien's mouth a second inner set of <a href="Pharyngeal_jaws" class="mw-redirect" title="Pharyngeal jaws">pharyngeal jaws</a> 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 mechanical.<a href="#cite_note-burster-8">[7]</a> His mock-up of the Alien was created using parts from an old <a href="Rolls-Royce_(car)" class="mw-redirect" title="Rolls-Royce (car)">Rolls-Royce</a> car, rib bones and the <a href="Vertebrae" class="mw-redirect" title="Vertebrae">vertebrae</a> from a snake, molded with plasticine. The Alien's <a href="Animatronics" title="Animatronics">animatronic</a> head, which contained 900 moving parts, was designed and constructed by special effects designer <a href="Carlo_Rambaldi" title="Carlo Rambaldi">Carlo Rambaldi</a>.<a href="#cite_note-doc-7">[6]</a> Giger and Rambaldi together would win the 1980 <a href="Academy_Award_for_Visual_Effects" class="mw-redirect" title="Academy Award for Visual Effects">Academy Award for Visual Effects</a> for their design of the Alien.

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 would be used. Scott was inspired by a photograph of <a href="Leni_Riefenstahl" title="Leni Riefenstahl">Leni Riefenstahl</a> standing next to a 6 ft 4 in (1.93 m) <a href="Nuba_peoples" title="Nuba peoples">Nuba</a> man.<a href="#cite_note-11">[10]</a> The casting director found 6 ft 10 in (2.08 m), rail-thin graphic designer <a href="Bolaji_Badejo" title="Bolaji Badejo">Bolaji Badejo</a> in a London pub. Badejo went to <a href="Tai_chi" title="Tai chi">tai chi</a> and <a href="Mime_artist" title="Mime artist">mime</a> classes to learn how to slow down his movements.<a href="#cite_note-doc-7">[6]</a>

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 <a href="Vagina_dentata" title="Vagina dentata">vagina dentata</a>."<a href="#cite_note-burster-8">[7]</a>

This creature has no specific name; it was called an alien and an organism in the first film. It has also been referred to as a creature,<a href="#cite_note-A2-4">[3]</a> a serpent,<a href="#cite_note-AvP-12">[11]</a> a beast,<a href="#cite_note-A3-5">[4]</a> a dragon,<a href="#cite_note-A3-5">[4]</a> a monster,<a href="#cite_note-A2-4">[3]</a> a nasty, or simply, a thing.<a href="#cite_note-A1-13">[12]</a> The term xenomorph (lit. "alien form" from the Greek xeno-, which translates as either "other" or "strange", and -morph, which denotes shape) was first used by the character Lieutenant Gorman in <a href="Aliens_(film)" title="Aliens (film)">Aliens</a><a href="#cite_note-A2-4">[3]</a> to refer to extraterrestrial life in general. The term was erroneously assumed by some fans<a href="#cite_note-14">[13]</a> to refer specifically to this creature, and the word was used by the producers of some merchandise.<a href="#cite_note-15">[14]</a>

<div class="mw-heading mw-heading2"><h2 id="Characteristics">Characteristics</h2></div>

At its core, the xenomorph is a hostile parasitic pathogen (Chemical A0-3959X.91) whose mutable <a href="Enzyme" title="Enzyme">mechanisms</a> are signaled by perturbances to its chemistry. It evolves to assume biological and physiological traits of its host, thereby enabling it to adapt to its environment. 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.

<div class="mw-heading mw-heading3"><h3 id="Appearance">Appearance</h3></div>

When standing upright, the Aliens are bipedal in form, though, depending on their host species, they will adopt either a hunched stance or remain fully erect when walking, sprinting, or in hotter environments. Their overall stance and general behavior seem to result from the mixture of the respective DNA of the embryo and its host. They have a skeletal, <a href="Biomechanical_art" title="Biomechanical art">biomechanical</a> appearance and are usually colored in muted shades of black, gray, blue or bronze. Their body heat matches the <a href="Ambient_temperature" class="mw-redirect" title="Ambient temperature">ambient temperature</a> of the environment in which they are found, so they do not radiate heat, making them indistinguishable from their surroundings through <a href="Thermal_imaging" class="mw-redirect" title="Thermal imaging">thermal imaging</a>.<a href="#cite_note-A2-4">[3]</a><a href="#cite_note-AvP-12">[11]</a> In most of the films, adult Aliens are capable of running and crawling along ceilings, walls, and other hard surfaces.<a href="#cite_note-A2-4">[3]</a><a href="#cite_note-A3-5">[4]</a> They have great physical strength, having been shown to be capable of breaking through welded steel doors over time.<a href="#cite_note-A2-4">[3]</a>

Aliens have segmented, blade-tipped tails. The sharp tip was initially a small, scorpion-like barb,<a href="#cite_note-A1-13">[12]</a> but from Aliens onwards the blade design increased in size and changed in appearance to more closely resemble a slashing weapon.<a href="#cite_note-A2-4">[3]</a><a href="#cite_note-AvP-12">[11]</a> 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,<a href="#cite_note-Mutation-21">[19]</a> 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 <a href="Predator_(fictional_species)" title="Predator (fictional species)">Predator</a> with seemingly little effort.

They have elongated, cylindrical <a href="Skull" title="Skull">skulls</a> with eyes underneath the "visor". In the novelization of Alien, the character Ash speculates that the xenomorphs "see" by way of electrical impulse, similar to some fish's <a href="Ampullae_of_Lorenzini" title="Ampullae of Lorenzini">Ampullae of Lorenzini</a>. This method is illustrated in the original <a href="Aliens_Versus_Predator_(1999_video_game)" title="Aliens Versus Predator (1999 video game)">Aliens Versus Predator PC game</a> and reused for the <a href="Predalien" class="mw-redirect" title="Predalien">Predalien</a> 28 years later. The Alien's <a href="Pharyngeal_jaw" title="Pharyngeal jaw">inner set of jaws</a> is powerful enough to smash through bone and metal.<a href="#cite_note-AvP-12">[11]</a> How the creatures see is uncertain; in Alien 3, a spherical lens was used to illustrate the Alien's <a href="Point-of-view_shot" title="Point-of-view shot">point of view</a>, 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.<a href="#cite_note-A2-4">[3]</a> 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,<a href="#cite_note-Creature_FX-22">[20]</a> 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 <a href="Webbed_feet" class="mw-redirect" title="Webbed feet">webbed</a>, six-fingered hands. In Aliens, the number of fingers is reduced to three, with two "paired" and a single, opposable thumb. The fingers are also 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.<a href="#cite_note-AVPmaking-23">[21]</a>

Aliens have been alternatively portrayed as both <a href="Plantigrade" title="Plantigrade">plantigrade</a> and <a href="Digitigrade" title="Digitigrade">digitigrade</a> organisms, usually relative to their hosts. 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.<a href="#cite_note-Beauties_and_the_Beast-24">[22]</a> The human-spawned Alien warriors would revert to a plantigrade posture in Alien vs. Predator.

<div class="mw-heading mw-heading3"><h3 id="Physiology">Physiology</h3></div>

Alien blood contains concentrated <a href="Hydrofluoric_acid" title="Hydrofluoric acid">hydrofluoric acid</a> and <a href="Sulfuric_acid" title="Sulfuric acid">sulfuric acid</a> 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. <a href="Ron_Cobb" title="Ron Cobb">Ron Cobb</a> suggested the idea of the Alien having acidic 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.<a href="#cite_note-25">[23]</a> 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.<a href="#cite_note-fluidnotblood-26">[24]</a> In the Aliens vs. Predator: Requiem documentary "Science of the Alien", it is hypothesized that the Aliens' acid blood could contain <a href="Sulfuric_acid" title="Sulfuric acid">sulfuric acid</a> 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 organism's protection system against its own acidic blood is a bio-organically produced <a href="Teflon" class="mw-redirect" title="Teflon">Teflon</a>-like insulation.<a href="#cite_note-27">[25]</a> 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 <a href="Spitting_cobra" title="Spitting cobra">spitting cobra</a>, they use it to blind their victims.<a href="#cite_note-A3-5">[4]</a><a href="#cite_note-A4-28">[26]</a>

Aliens can produce a thick, strong <a href="Resin" title="Resin">resin</a> that they use to build their hives and to <a href="Cocoon_(silk)" class="mw-redirect" title="Cocoon (silk)">cocoon</a> their victims, and they can use the walls of their hives as <a href="Camouflage" title="Camouflage">camouflage</a>.<a href="#cite_note-MacFarland-29">[27]</a> 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.<a href="#cite_note-MacFarland-29">[27]</a>

<div class="mw-heading mw-heading3"><h3 id="Intelligence">Intelligence</h3></div>

During various events in Alien Resurrection on the USM Auriga, the crossover film Alien vs. Predator, Aliens on the LV-426 colony Hadley's Hope, and Alien 3 when they are trying to trap the alien, the species displayed <a href="Observational_learning" title="Observational learning">observational learning</a> and <a href="Problem_solving" title="Problem solving">problem-solving</a> skills.<a href="#cite_note-A2-4">[3]</a><a href="#cite_note-A4-28">[26]</a> It's also shown the ability to operate machinery at a very basic level, with the queen in <a href="Aliens_(film)" title="Aliens (film)">Aliens</a> depicted operating an elevator.<a href="#cite_note-mother-30">[28]</a>

On the USM Auriga in Alien Resurrection, the aliens kill one of their own, using its blood to melt through their enclosure and escape (according to the novelization, it was inspired to do so from genetic memories inherited from the original Ripley); 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 by flicking it, indicating awareness of the effects of their acid blood.

In the original film, it is implied that the alien cut the lights on board the Nostromo. On LV-426, the xenomorphs cut power in a section of the complex to gain access to the humans.

The novel for the film Aliens includes a scene where Bishop speculates on the reason why the queen established her "nest" at the base's main power plant. His reasons range from an animalistic drive for warmth to an intentional strategic selection (any attacker could not 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. In Alien 3, Ripley and the inmates try luring the Alien into the lead works. It becomes obvious that the Alien recognized the trap and the danger it held. At one point, it hesitates to enter the lead works. Later, it hunts down most of the prisoners just before going into the lead works.

<div class="mw-heading mw-heading3"><h3 id="Life_cycle">Life cycle</h3></div>

Aliens are <a href="Eusocial" class="mw-redirect" title="Eusocial">eusocial</a> life-forms with a <a href="Caste_(biology)" class="mw-redirect" title="Caste (biology)">caste</a> system ruled over by a queen.<a href="#cite_note-A2-4">[3]</a><a href="#cite_note-AvP-12">[11]</a><a href="#cite_note-A4-28">[26]</a> Their life cycle comprises several distinct stages: they begin their lives as an egg, which hatches a <a href="Parasitoid" title="Parasitoid">parasitoid</a> larval form known as a facehugger, which then attaches itself to a living <a href="Host_(biology)" title="Host (biology)">host</a> by, as its name suggests, latching onto its face. In the <a href="Alien_3" title="Alien 3">Alien 3</a> novelization, Ripley commented that this parasitoid would probably be able to use any host from as small as a <a href="Cat" title="Cat">cat</a> to as large as an <a href="Asian_elephant" title="Asian elephant">Asian elephant</a>.

The facehugger then "impregnates" the host with an <a href="Embryo" title="Embryo">embryo</a>, known as a "chestburster".<a href="#cite_note-31">[c]</a> During this time, the host is kept in an unconscious state with normal vital functions. After depositing the embryo inside the host, the facehugger dies and releases its hold on its victim's face and head, as shown in Alien and Aliens. The host will then experience a short period of near-symptomless recovery during which the embryo is in <a href="Gestation" title="Gestation">gestation</a>, followed by the sudden and painful eruption of the chestburster from the host's chest, resulting in their death. The chestburster then matures to an adult phase, shedding its skin and replacing its cells with <a href="Polarization_(waves)" title="Polarization (waves)">polarized</a> <a href="Silicon" title="Silicon">silicon</a>.

Due to <a href="Horizontal_gene_transfer" title="Horizontal gene transfer">horizontal gene transfer</a> during the gestation period, the alien also takes on some of the basic physical attributes of the host from which it was born (something noticed by Ripley in Alien 3, when the xenomorph plaguing the complex <a href="Quadrupedalism" title="Quadrupedalism">moved on four limbs</a>, having gestated within a quadruped (a dog in the theatrical release and an ox in the <a href="Director's_cut" title="Director's cut">director's cut</a>) whereas all the others she had previously seen had gestated within humans/<a href="Bipedalism" title="Bipedalism">bipeds</a>), allowing the individual alien to adapt to the host's environment (breathe the air, etc.). This is also shown in the two live-action crossover films, <a href="Alien_vs._Predator_(film)" title="Alien vs. Predator (film)">Alien vs. Predator</a> (2004) and <a href="Aliens_vs._Predator%3A_Requiem" title="Aliens vs. Predator: Requiem">Aliens vs. Predator: Requiem</a> (2007), where an embryo, having gestated within a Predator/Yautja, displayed Predator/Yautja physical traits (arthropod-like <a href="Mandible" title="Mandible">mandibles</a>) from eruption onwards.

This process of horizontal gene transfer is also shown to be two-way; in <a href="Alien_Resurrection" title="Alien Resurrection">Alien Resurrection</a> (film and novelization), Ripley's clone, Ripley-8, is shown exhibiting numerous xenomorph characteristics, physical and behavioural; this is touched more upon in the novelization (chapter 4), where it is described that when a host is infested with an xenomorph embryo, it does not just infest the host like a parasite, but also like a virus, "a major breakthrough in adaptive evolution ... a way to guarantee that any host, any host at all, would provide whatever it was the developing embryo needed, even if/when the host's body was inadequate."

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 <a href="Ant" title="Ant">ants</a> 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.

<div class="mw-heading mw-heading4"><h4 id="Queen">Queen</h4></div>

Queen aliens are significantly larger and stronger than the normal adults, being approximately 4.5 metres (15 ft) tall.<a href="#cite_note-32">[29]</a> Their body structure also differs, 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 <a href="Ovipositor" title="Ovipositor">ovipositor</a> attached to their lower torso, similar to a queen termite's. Like <a href="Hymenoptera" title="Hymenoptera">some</a> insect <a href="Queen_(bee)" class="mw-redirect" title="Queen (bee)">queens</a>, there appears to be no need for an Alien queen's eggs to be fertilized.<a href="#cite_note-AvP-12">[11]</a><a href="#cite_note-A4-28">[26]</a> When attached to her ovipositor, the queen is supported by a "biomechanical <a href="Throne" title="Throne">throne</a>"<a href="#cite_note-33">[30]</a> 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 <a href="James_Cameron" title="James Cameron">James Cameron</a> to introduce a concept he had initially conceived for a spec script called Mother,<a href="#cite_note-mother-30">[28]</a> 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.<a href="#cite_note-mother-30">[28]</a> In that vein, some critics have compared it to <a href="Grendel's_mother" title="Grendel's mother">Grendel's mother</a>.<a href="#cite_note-34">[31]</a><a href="#cite_note-35">[32]</a>

The queen was designed by Cameron in collaboration with special effects artist <a href="Stan_Winston" title="Stan Winston">Stan Winston</a>, based upon an initial painting Cameron had done at the start of the project. The Winston Studio created a test foamcore queen before constructing the full hydraulic <a href="Puppet" title="Puppet">puppet</a> 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 '<a href="https://en.wiktionary.org/wiki/less_is_more" class="extiw external" title="wikt:less is more">less is more</a>' style of photography. Subsequently, the movie won an <a href="Academy_Award_for_Visual_Effects" class="mw-redirect" title="Academy Award for Visual Effects">Oscar for Visual Effects</a>. An adult queen was to reappear in Alien Resurrection. The original mechanical head previously used in Aliens was provided by <a href="Bob_Burns_III" title="Bob Burns III">Bob Burns</a> 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 <a href="Alien_vs._Predator_(film)" title="Alien vs. Predator (film)">Alien vs. Predator</a> in favour of the original black color scheme.<a href="#cite_note-AVPmaking-23">[21]</a>

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 six 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 <a href="Animatronic" class="mw-redirect" title="Animatronic">animatronic</a> queen had 47 points of hydraulic motion.<a href="#cite_note-AVPmaking-23">[21]</a>

Aliens vs. Predator: Requiem (2007) introduced a younger form of the full-grown queen, albeit with traits inherited from its <a href="Predator_(alien)" class="mw-redirect" title="Predator (alien)">Predator</a> 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.<a href="#cite_note-belly-36">[33]</a> 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.<a href="#cite_note-autogenerated1-37">[34]</a>

Adult xenomorphs are capable of creating their own reproductive egg ("ovamorph") by <a href="Pupa#Cocoon" title="Pupa">embedding</a> their prey into an organic substance that (in theory) metabolically reacts to merge host-parasite <a href="DNA" title="DNA">genetic material</a>. The entire process is xeno-dominant, resulting in a facehugger. The eggs laid by the queen are ellipsoidal, leathery objects between one-half and one meter (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".<a href="#cite_note-littlegiger-38">[35]</a> 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".<a href="#cite_note-littlegiger-38">[35]</a>

The interior of the original egg was composed of "Nottingham lace" (<a href="Caul_fat" title="Caul fat">caul fat</a>), 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.<a href="#cite_note-doc-7">[6]</a> 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 the Director's Cut of Alien, 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 facehugger inside the egg. According to the novelization for Resurrection, the Egg, in and of itself, could be considered a living organism in its own right.

<div class="mw-heading mw-heading4"><h4 id="Facehugger">Facehugger</h4></div>

A facehugger is the second stage in the Alien's metamorphosis. 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 <a href="Chelicerata" title="Chelicerata">chelicerate</a> <a href="Arthropoda" class="mw-redirect" title="Arthropoda">arthropods</a> such as <a href="Arachnid" title="Arachnid">arachnids</a> and <a href="Horseshoe_crab" title="Horseshoe crab">horseshoe crabs</a>.

The facehugger is a <a href="Parasitoid" title="Parasitoid">parasitoid</a>; 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 to the host in order to render it unconscious and immobile.<a href="#cite_note-39">[36]</a><a href="#cite_note-WYreport-2">[1]</a> During a successful attachment, the facehugger will insert an <a href="Ovipositor" title="Ovipositor">ovipositor</a> down the host's throat while simultaneously implanting an embryo. The host is kept alive, and the creature breathes for the host.<a href="#cite_note-A1-13">[12]</a> Attempts to remove facehuggers generally prove fatal to the host,<a href="#cite_note-A2-4">[3]</a> 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.<a href="#cite_note-A1-13">[12]</a>

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 16 hours. Once this happens, the parasite detaches, crawls away, and dies.<a href="#cite_note-WYreport-2">[1]</a> 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 <a href="Cannibalization_(parts)" title="Cannibalization (parts)">that "commands" the host's cells to grow the chestburster</a>, as opposed to an implanted embryo.<a href="#cite_note-40">[37]</a> This is an alternate explanation to <a href="Horizontal_gene_transfer" title="Horizontal gene transfer">horizontal gene transfer</a> as to how the resulting xenomorph 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.<a href="#cite_note-dvd-41">[38]</a> 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 was revealed once the helmet was removed. Scott and Giger realized 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.<a href="#cite_note-42">[39]</a>

<a href="Dan_O'Bannon" title="Dan O'Bannon">Dan O'Bannon</a> initially conceived the facehugger as somewhat resembling an octopus, possessing tentacles. However, when he received <a href="H._R._Giger" title="H. R. Giger">H. R. Giger</a>'s designs, which substituted finger-like digits for tentacles, 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 <a href="Ron_Cobb" title="Ron Cobb">Ron Cobb</a>. 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 <a href="Foam_rubber" title="Foam rubber">foam rubber</a> sculpture of the facehugger was produced, O'Bannon asked that it should remain unpainted, believing the rubber, which resembled human skin, was more plausible.<a href="#cite_note-43">[40]</a>

There has been some debate about the sexual appearance of the facehugger, some saying it unmistakably resembles female genitalia.<a href="#cite_note-44">[41]</a>

In <a href="Aliens_(film)" title="Aliens (film)">Aliens</a>, the facehuggers were redesigned by <a href="Stan_Winston" title="Stan Winston">Stan Winston</a> 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 is 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 was planned but ultimately dropped, a "super-facehugger" that would carry the embryo of the queen Alien.<a href="#cite_note-A3org-45">[42]</a> This super-facehugger is briefly glimpsed in the Assembly cut of Alien 3 but not identified as such.<a href="#cite_note-A3org-45">[42]</a><a href="#cite_note-46">[43]</a> It made a brief appearance in the canonical Alien book called Alien: Sea of Sorrows, set after the events of Alien Resurrection, about the grandson of Ripley Clone 8, Ellen Ripley's clone.

<div class="mw-heading mw-heading4"><h4 id="Chestburster">Chestburster</h4></div>

After impregnation, facehuggers die and the embryo's host wakes up afterward, showing no considerable outward negative symptoms and a degree of <a href="Amnesia" title="Amnesia">amnesia</a> regarding events at the time of implantation. Symptoms build acutely after detachment of the facehugger, the most common being sore throat, slight <a href="Nausea" title="Nausea">nausea</a>, increased congestion, and moderate to extreme hunger.<a href="#cite_note-A1-13">[12]</a> In later stages where the <a href="Incubation_period" title="Incubation period">incubation period</a> is extended in preparation of a queen birth, symptoms will include a shortness of breath, exhaustion, and <a href="Hemorrhaging" class="mw-redirect" title="Hemorrhaging">hemorrhaging</a> (detectable through biological scanners and present in nosebleeds or other seemingly random bleeding incidents), as well as chest pains caused by a lack of space due to the chestburster's presence or even premature attempts to escape the host.

The incubating embryo <a href="Horizontal_gene_transfer" title="Horizontal gene transfer">takes on some of the host's</a> <a href="DNA" title="DNA">DNA</a> or <a href="Phenotypic_trait" title="Phenotypic trait">traits</a>, such as <a href="Bipedalism" title="Bipedalism">bipedalism</a>, <a href="Quadrupedalism" title="Quadrupedalism">quadrupedalism</a>,<a href="#cite_note-A3-5">[4]</a> possessing the <a href="Mandible" title="Mandible">mandibles</a> of a <a href="Predator_(alien)" class="mw-redirect" title="Predator (alien)">Predator</a>,<a href="#cite_note-AvP-R-47">[44]</a> and other structural changes that enable adaptation to its new environment. According to Weyland-Yutani medical 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; the only exceptions to this are from human-xenomorph hybrid hosts like the cloned Ripley 8, who survived an extraction procedure without issue.

Over the course of one to twenty-four 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.

When a chestburster erupts from the body of a human host, it is less than 30 centimetres (12 in) tall, although the embryo can vary in size from a guinea pig to a large dog depending on the size and species of the host. 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, as well as find a source of nutrition. 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.<a href="#cite_note-48">[d]</a> The chestburster is shown to have molted before reaching maturity.<a href="#cite_note-A1-13">[12]</a> In Aliens vs. Predator: Requiem, Alien warriors who are still growing are shown, displaying shed skin. In the unrated cut, the <a href="#Predalien">Predalien</a> is shown wiping off its final molted skin at the film's start.

The chestburster was designed by <a href="Alien_(film)" title="Alien (film)">Alien</a> director <a href="Ridley_Scott" title="Ridley Scott">Ridley Scott</a> and constructed by special effects artist <a href="Roger_Dicken" title="Roger Dicken">Roger Dicken</a>.<a href="#cite_note-woman-49">[45]</a> Giger had produced a model of a chestburster that resembled a "degenerate plucked turkey"<a href="#cite_note-50">[46]</a> 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".<a href="#cite_note-burster-8">[7]</a> 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.<a href="#cite_note-Winston-51">[47]</a> This concept would be abandoned in Alien Resurrection, but it would return in Alien: Covenant.

<div class="mw-heading mw-heading3"><h3 id="Cocoon">Cocoon</h3></div>

The xenomorph lifecycle is expanded in the movie <a href="Alien%3A_Romulus" title="Alien: Romulus">Alien: Romulus</a> with the introduction of a "cocoon" stage, which bridges the gap between the chestburster and the fully-grown adult xenomorph stages as witnessed by the characters Bjorn and Kay while aboard the derelict Renaissance space station. It is shown that a chestburster which had emerged from their crewmate Navarro had attached itself to a wall and built a biomechanical protective cocoon around itself after shedding its skin. While inside the cocoon, the chestburster <a href="Pupa" title="Pupa">transformed</a> into a fully-grown adult drone xenomorph.<a href="#cite_note-52">[48]</a>

<div class="mw-heading mw-heading3"><h3 id="Alternative_forms">Alternative forms</h3></div>

Aliens take on various forms <a href="Horizontal_gene_transfer" title="Horizontal gene transfer">depending on the characteristics of their hosts</a>. 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 as the Neomorph and Deacon.

<div class="mw-heading mw-heading4"><h4 id=""Dragon"">"Dragon"</h4></div>

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 <a href="Alien_3" title="Alien 3">Alien 3</a>. 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 from which it was spawned (a <a href="Dog" title="Dog">dog</a> in the theatrical cut, or as an <a href="Ox" title="Ox">ox</a> in the novelized version and the 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 <a href="Quadrupedalism" title="Quadrupedalism">quadrupedal</a>, has <a href="Digitigrade" title="Digitigrade">digitigrade</a> 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 <a href="Thermal_shock" title="Thermal shock">thermal shock</a>.

Originally, H. R. Giger was approached on July 28, 1990, by <a href="David_Fincher" title="David Fincher">David Fincher</a> and <a href="Tim_Zinnemann" title="Tim Zinnemann">Tim Zinnemann</a>, 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. As 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 <a href="Felidae" title="Felidae">feline</a>—a <a href="Leopard" title="Leopard">panther</a> or something. It had a kind of skin that was built up from other creatures—much like a <a href="Symbiosis" title="Symbiosis">symbiosis</a>." However, when Tom Woodruff and Alec Gillis of <a href="Amalgamated_Dynamics" title="Amalgamated Dynamics">Amalgamated Dynamics</a> 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.<a href="#cite_note-53">[49]</a>

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 <a href="Amalgamated_Dynamics" title="Amalgamated Dynamics">Amalgamated Dynamics</a> personnel gave a series of interviews that minimized Giger's contribution.

However, Giger would comment that he thought the resulting film was "okay" and that the Alien was "better than in the second film".<a href="#cite_note-54">[50]</a>

<div class="mw-heading mw-heading4"><h4 id="Newborn">Newborn</h4></div>

In <a href="Alien_Resurrection" title="Alien Resurrection">Alien Resurrection</a>, 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 <a href="Humanoid" title="Humanoid">humanoid</a> <a href="Mutant_(fiction)" class="mw-redirect" title="Mutant (fiction)">mutant</a> hybrid. Physically, the human/Alien Newborn is very different from other alien young, being larger, with pale, translucent skin, a <a href="Skull" title="Skull">skull</a>-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 <a href="Joss_Whedon" title="Joss Whedon">Joss Whedon</a> 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 <a href="Jean-Pierre_Jeunet" title="Jean-Pierre Jeunet">Jean-Pierre Jeunet</a> asked ADI to make the human/Alien <a href="Hybrid_(biology)" title="Hybrid (biology)">hybrid</a>, 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.

<div class="mw-heading mw-heading4"><h4 id="Predalien">Predalien</h4></div>

This variation is the result of a facehugger impregnating a <a href="Predator_(alien)" class="mw-redirect" title="Predator (alien)">Predator</a>. The "Predalien" was first depicted in a painting by <a href="Dave_Dorman" title="Dave Dorman">Dave Dorman</a>, and subsequently featured in the Aliens versus Predator comics and games. A Predalien chestburster debuted in the final scene of <a href="Alien_vs._Predator_(film)" title="Alien vs. Predator (film)">Alien vs. Predator</a> (2004), but did not make a full on film appearance as an adult until <a href="Aliens_vs._Predator%3A_Requiem" title="Aliens vs. Predator: Requiem">Aliens vs. Predator: Requiem</a> (2007).

The Predalien shares many characteristics with its hosts, such as long hair-like appendages, <a href="Mandible" title="Mandible">mandibles</a>, skin color, blood that glows in the dark (though still acidic), 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.<a href="#cite_note-55">[51]</a>

<div class="mw-heading mw-heading4"><h4 id="Deacon">Deacon</h4></div>

The dark-blue Deacon is a different species that makes an appearance in <a href="Prometheus_(2012_film)" title="Prometheus (2012 film)">Prometheus</a>, though it clearly shares traits similar to the xenomorph, including a similar life-cycle. The Deacon is the result of a "Trilobite" (which takes its name from <a href="Trilobites" class="mw-redirect" title="Trilobites">a group of extinct marine arthropods</a>), a large facehugger-like creature, attacking and impregnating an Engineer. After some time spent gestating, it will burst out of its host, with the notable difference that it is "born" almost fully developed. The Deacon's emergence drew inspiration from the birth of <a href="Foal" title="Foal">foals</a>, with the iridescent appearance for its skin being based on the equine placenta,<a href="#cite_note-56">[52]</a> and the protruding jaw inspired by the <a href="Goblin_shark" title="Goblin shark">goblin shark</a>.<a href="#cite_note-57">[53]</a>

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's deadly back spines.

<div class="mw-heading mw-heading4"><h4 id="Neomorph">Neomorph</h4></div>

The pale-white Neomorph is featured in <a href="Alien%3A_Covenant" title="Alien: Covenant">Alien: Covenant</a>.<a href="#cite_note-neo-19">[17]</a> It was created through exposure to spores found growing on the Engineer homeworld. The embryonic Neomorph gestates inside the host until it bursts out from whatever location in said host they've metastasized (one is seen gaining entry through the ear and emerging from the spine, while a second one, nasally inhaled, later erupts from the host's throat; other means of entry and egress are not made clear), using mostly its head, which is sharp and pointed, not unlike the Deacon. Similarly, the Deacon and Neomorph share the same type of Pharyngeal Jaw (similar to that of a Moray Eel) among other distinctly less biomechanical traits than the traditional xenomorph, though the latter does share with the Neomorph a tail strong enough to cause grievous injury; at one point, a violently thrashing Neomorph tail is seen to instantly remove a human jaw. This behavior is just one of several demonstrating the Neomorph's far more feral nature; they are voracious predators, often eating the corpses of their victims, and they appear to lack their xenomorph cousins' hive structure, possibly since they propagate through mutated animal life.<a href="#cite_note-covenant-18">[16]</a>

<div class="mw-heading mw-heading4"><h4 id="Offspring">Offspring</h4></div>

The Offspring, featured in <a href="Alien%3A_Romulus" title="Alien: Romulus">Alien: Romulus</a>, is the result of pregnant character Kay injecting a serum derived from the Xenomorph's genome into her neck, leading to a rapid mutation of her unborn fetus. The creature is violently birthed in an egg, hatches, and rapidly grows to over 8 feet tall. It possesses fleshy skin, black eyes, a tail, a Xenomorph-like tongue with teeth, dorsal tubes, and overall facial similarities to the Engineers. It terrorizes the remaining crew of the Corbelan, damaging the android Andy and fatally feeding off of its mother Kay before pursuing Rain, but is finally defeated by her jettisoning it into the planetary rings below. Although there is no evidence that the Offspring possesses higher thinking, it smiles when in an advantageous position.

The Offspring was portrayed by basketball player <a href="Robert_Bobroczkyi" title="Robert Bobroczkyi">Robert Bobroczkyi</a> wearing full body <a href="Prosthetic_makeup" title="Prosthetic makeup">prosthetic makeup</a> created by Legacy Effects, with the exception of the creature's tail which was CGI. Along with adding Xenomorph elements to a human, the design tried to invoke the Engineers that created the race.<a href="#cite_note-offspring2-58">[54]</a><a href="#cite_note-offspring3-59">[55]</a>

<ul><li><a href="Dracunculiasis" title="Dracunculiasis">Dracunculiasis</a>, a real parasitic infection by a worm (up to 1 m long) that emerges from the body one year after infection</li></ul>
