(Updated as of 9/01/2019)

Hello yet again discerning AVP fans, this time I am listing only those Xenomorphs that I believe to be canonical or canonically feasible, in the case that reading my previous blog post on the fully comprehensive Xenomorph classification system that I have created had caused anyone to mistakenly believe that I interpret all conceived of Xenomorph varieties from offical media as canonical, which of course I don't.

I also include appropriate name changes for several Xenomorph varieties as well as Xenomorph hive and caste dynamics that encompass the coordinated societal functions of all of the standard and auxiliary caste varieties that I have listed as canonical.

Pre-list contents:

  • Notes
  • Xenomorph name changes
  • Xenomorph caste dynamics
  • Xenomorph hive dynamics
  • Xenomorph XX121 gender classification


  • Some Xenomorphs previously found in the Auxiliary Castes category are now listed as variants of specific castes:
    • Venator (Lurker) → Drone variant: All characteristics of the Lurker point to it being a further development of the Drone.
    • Vanguard (Raven) → Drone/Venator (Lurker) variant: Several characteristics of the Vanguard (Raven) are similar to those of Drones/Venators (Lurkers).
  • The 'Engineer' subsection of the Xenomorphs Spawned From Sentient Extraterrestrials section is now listed as 'Mala'kak' instead as it is that species' word for themselves in their native language as 'Yautja' is for the Predators.
  • While the feasibility of Xenomorphs being spawned from certain creatures is not unrealistic, for some of them the current examples of the resultant Xenomorph have unrealistic or unlikely designs that differ from what one would expect as determined by the DNA reflex.

Xenomorph name changes

I have changed the names of some Xenomorph varieties to better suit what I believe their function is and to be more closely aligned with preexisting nomenclature (Praetorian, Palatine etc.), especially as the names of some varieties sound crude and 'StarCrafty'.

Official name Improved name Reason for renaming
Lurker Venator This is a continuation of the usage of ancient Roman military terminology, with Venators being hunters in the ancient Roman military, this reflects the ambush tactics of Lurkers as opposed to the mass assault tactics of Warriors.
Raven Vanguard I believe that the function of the Raven is inverse to that of a Praetorian, i.e instead of guarding the Xenomorph hive or rather the Queen in particular, the Vanguard is as it's name might suggest, a hive outer-perimeter patrol/ambush type caste.
Evolved Warrior Adapted Warrior 'Adapted' is more correct than 'Evolved' in this sense.
Royal Guard Lictor This is a continuation of the usage of ancient Roman terminology, with Lictors being bodyguards that were not as elite as the Praetorian Guard which in this usage is analogous to Royal Guard being Juvenile Praetorians.
Ravager Phalanx This is a continuation of the usage of ancient military terminology, with a Phalanx being a defensive formation composed of heavy infantry and this being roughly analogous to a Ravager as it is the equivalent of several Warriors in terms of offensive and defensive capability.
Colossal Ravager Heavy Phalanx (See above)
Carrier Pontifex This is a continuation of the usage of ancient Roman terminology, with Pontifex (or Pontiff rather) being a high priest and since priests love to proselytise it is an appropriate name for the Carrier as it throws Facehuggers that impregnate enemy hosts and spawn Xenomorphs, which in this sense is roughly analogous to proselytism.
Super Carrier Heavy Pontifex (See above)
War Empress Imperatrix This is a continuation of the usage of ancient Roman military terminology, with Imperator being an honorific title assumed by successful military commanders in the Roman republic and also from which the word emperor is derived, so because a War Empress is a Xenomorph Queen that has undergone a combat adaptation, this is fitting terminology that also does not confuse the creature with a Xenomorph Empress which is quite different.
Runner Scout 'Scout' more correctly describes it's function.
Crusher Aries This is a continuation of the usage of ancient Roman military terminology and the word 'crusher' is not evocatively correct as the distinctive attack of the creature is to ram a target with it's large head crest and break through obstacles like a battering ram (known in ancient Rome as an 'aries'), not crush something underfoot as it's name would suggest.

Xenomorph caste dynamics

  • Praetorian Egg/Facehugger: There is more than one way that Praetorians can occur within a Xenomorph hive, under normal circumstances other Xenomorph castes; such as Drones and Warriors; would metamorphose into Lictors and then Praetorians. However in the context of a Xenomorph hive defending against a dire threat, a quicker method of creating Praetorians may be necessary and this would be accomplished by the hive's Queen laying eggs containing Praetorian Facehuggers that impregnate hosts which would spawn Xenomorphs that then develop into a Praetorian more quickly than a Drone or Warrior would be able to metamorphose into one.
  • Vanguard (Raven): I believe that the function of the Vanguard (Raven) in a Xenomorph hive is inverse to that of a Praetorian, i.e instead of guarding the Xenomorph hive or rather the Queen in particular, the Vanguard (Raven's) purpose is as a hive outer-perimeter patrol/ambush type caste. I reckon this as it has characteristics in common with Venators (Lurkers) which are an ambush caste and in Aliens: Colonial Marines it is encountered in an area beneath the Xenomorph hive proper, indicating to me that it was patrolling that area to ensure that the hive's three dimensional perimeter would not be breached from below and it would also probably function as a single organism instead of in groups like other castes.
  • Praetorian: Whilst Praetorians can metamorphose from castes such as Drones and Warriors, this can only occur when there is a Xenomorph Queen to direct them to do so and likely also secrete the royal jelly or similar substance that such a metamorphosis would require.
  • Queen: A Xenomorph Queen can only occur by being spawned from a host impregnated by a Royal Facehugger, they cannot metamorphose from any other caste except Praetorians which can only occur with a Queen anyway. This is certain as it is fundamental to the hunting practises of the Yautja that they know exactly how many Xenomorphs would be spawned in an area they have seeded with ovomorphs to prevent a Xenomorph infestation as the result of a failed hunt etc. from 'xenoforming'/destroying an entire ecosystem or even continent. The Yautja have technology able to detect Royal Facehugger eggs laid by captive Xenomorph Queens and destroy or seperate them from the ovomorphs they do use to seed an area for Xenomorph hunting. Though of course there would be 'wild' Xenomorph Queens and also specific hunts where the Yautja would have seeded an area with a Queen Xenomorph so that a Queen hunt could occur, though obviously the hunting party would know exactly how to go about doing so as to prevent a Xenomorph population overspill beyond what they would be able to contain, such as using islands or regions isolated by vast barren areas with no suitable host species/nourishment etc. as hunting grounds.
  • King: As Xenomorph Kings are only known to be found in the largest hives, they would most likely spawn/metamorphose under conditions similar to those that would necessitate an Empress. So under normal hive territory/population development conditions the Xenomorph King would be spawned/metamorphosed some time after an Empress as the Empress caste is more relevant to the dynamics of an expanding Xenomorph hive, with the King being more of a territorial consolidation / aggressive expansion caste due to it's immense and readily available combat capability.

Xenomorph hive dynamics

  • Advanced territory/population castes: There are five Xenomorph castes that only occur when a hive has a large enough population/territory and on such a scale these five castes; throughout a normal hive development process; would occur in this order.
    • Lictor
    • Praetorian
    • Vanguard — 'Praetorian' Venator
    • Empress
    • King
  • War castes: War castes are Xenomorph castes that are only spawned/metamorphosed when a Xenomorph hive is either defending itself against a dire threat or expanding into territory with strong resistance such as human military.
    • Early life cycle war castes:
      • Praetorian Egg*
      • Hyperfertile Egg*
      • Praetorian Facehugger*
    • Adult war castes:
      • Venator
      • Adapted Warrior
      • Phalanx
        • Heavy Phalanx
      • Pontifex*
        • Heavy Pontifex*
      • Imperatrix*

*These Xenomorphs are spawned/metamorphosed to quickly bolster numbers whilst in defense of a hive rather than during aggressive expansion.

Xenomorph XX121 gender classification

I prefer to view the Xenomorph gender topic from a purely functional perspective, meaning; in terms only of the polarity of known Xenomorph reproductive processes; that I would classify all Xenomorphs as genderless except for the Queen, which I would describe as asexual and not female (since it does not require a male or anything other than its own physiology in order to reproduce), with facehuggers being male as to reproduce they require another organism to impregnate.

An exception to this is the juvenile Predalien Queen from Aliens vs. Predator: Requiem which I would describe as male since it was only ever known to reproduce by directly impregnating another. Though ultimately it was probably an asexual male, presuming it was also capable of oviparity like a regular Xenomorph Queen.

  • Queen: Asexual
  • Facehugger: Male
  • AVP:R Predalien Queen: Male or asexual male
  • All other Xenomorphs: Genderless

Caste: Queen → Facehugger → Drone etc.

Gender polarity: Asexual → Male → Genderless

This blog post covers every Xenomorph variety; beyond the basic stages of the creature's life cycle; that has ever appeared in any sort of official media from the Aliens and Aliens vs. Predator franchises that I interpret as being canonical or canonically feasible creatures.

These Xenomorph varieties are categorized into three primary distinctions with subsequent secondary and tertiary distinctions:

1. Expanded Universe Xenomorph Castes

  • Standard Xenomorph caste variants
    • Early life cycle
      • Ovomorph
      • Facehugger
      • Chestburster
    • Adult castes
      • Drone
      • Warrior
      • Praetorian
      • Queen
  • Auxiliary Xenomorph castes

2. Xenomorphs Spawned From Nonhuman Hosts

  • Sentient extraterrestrials
  • Animals
    • Terrestrial
    • Aquatic
    • Flight capable

3. Altered Xenomorph Varieties

  • Mutant Xenomorphs
    • Naturally occurring mutations
    • Unnatural mutations
  • Genetically engineered Xenomorphs
    • Spliced Xenomorphs (weaponized)
  • Hybrid/tribrid Xenomorphs

1. Expanded Universe Xenomorph Castes

This section contains variations of the standard Xenomorph varieties from the early life cycle (Ovomorph, Facehugger, Chestburster) and adult castes (Drone, Warrior, Praetorian, Queen) and also auxiliary Xenomorph castes that have appeared in the official media of the feature films and expanded universe lore that I interpret as being canonical or canonically feasible creatures.

Standard Xenomorph caste variants

This subsection contains variations of the standard Xenomorph castes from the early life cycle (Ovomorph, Facehugger, Chestburster) and adult castes (Drone, Warrior, Praetorian, Queen).

Early life cycle



A Praetorian Egg from Aliens versus Predator: Extinction

Praetorian Egg

Main article: Ovomorph (Egg)#Praetorian Eggs
Praetorian Eggs are a variation of the normal Egg that costs more resources and effort to create than the standard egg. Different from a normal Egg, Praetorian Eggs are thicker and affect a more greenish coloration. They molt from normal Eggs, the Facehugger within changing as they do, becoming a Praetorian Facehugger. Such Facehuggers always give rise to a Praetorian, regardless of host.

Royal Facehugger Egg

These eggs contain Royal Facehuggers that is capable of implanting an embryonic Queen.

A standard and Hyperfertile Egg

Hyperfertile Egg

Main article: Ovomorph (Egg)#Hyperfertile Eggs

Hyperfertile Eggs are an evolution to the typical Ovomorph that can quickly grow the Hive's numbers. Instead of one Facehugger to an Egg, these Eggs can hold anywhere from two to four, inversely proportional to how well the Hive is doing — if low in number, Eggs will hold up to four Facehuggers, but if the Hive is doing well, only two or sometimes just one.

Praetorian Facehugger

Main article: Praetorian Facehugger
The Praetorian Facehugger is a special variant of the Facehugger that is capable of implanting an embryonic Praetorian. It is one of several means by which a Praetorian can come into existence. They are also essential in the creation of Ravagers and Carriers.

Royal Facehugger from Alien 3


Royal Facehugger from Aliens: Book One

Royal Facehugger

Main article: Royal Facehugger

The Royal Facehugger, also known as the Super Facehugger[1] or Queen Facehugger, is a special variant of Facehugger that is capable of implanting an embryonic Queen. While there is some debate as to how Queen Xenomorphs are created, one possible route involves a Royal Facehugger impregnating a host with a Queen Chestburster. Notably, Royal Facehuggers are capable of implanting more than one embryo into multiple hosts before they die, typically in the form of a second, regular Xenomorph embryo, which it is thought serves to act as a "guard" for the infant Queen.[2]



A Queen Chestburter from Aliens: Defiance

Queen Chestburster

Main article: Queen (caste)#Royal Jelly and Royal Facehuggers

Alien 3 also shows the Queen Chestburster itself to be physically different, with a partially developed head crest, well-developed legs and two pairs of arms, like a mature Queen.[3]

Adult castes



A Lurker


Main article: Lurker
The Lurker is a caste of Xenomorph very similar to the Drone. Lurkers are easily identified by their usually smooth head carapaces. Unlike the far more common Warrior caste which tend to employ direct assaults and swarm attacks, using sheer weight of numbers to overwhelm defenses and subdue their prey, Lurkers prefer to keep their distance and lurk in the shadows, only attacking when the time is right.

Hiya Toys figure of the Raven

Vanguard — 'Praetorian' Venator

Main article: Raven

The Raven resembles an ordinary bipedal Xenomorph, but larger, almost entirely encased in a bullet-proof, chitin carapace, and only walks with its large hind legs - like a Queen. Its tail has a distinct ridge of spines at the base of its harpoon-like blade. Its head possesses a ridged carapace, much like a Warrior, with a line of spikes along the top of its cranium. The Raven can also be heard making a "snarl" noise characteristic to Lurkers at times, further hinting that Lurkers may be a leadership caste.



The Prodos Games Evolved Warriors

Adapted Warrior

Main article: Warrior#Evolved Warrior

As a Xenomorph hive grows in size, on occasion, a Warrior will mutate into a unique type of its own. Highly adaptable, these creatures are often mistaken for a standard Warrior until it is too late for their enemies. Some of them are able to spray acid at close range onto multiple enemies at once, others can camouflage their exoskeleton to blend into their surroundings to leap upon their foes, and some of them are even able to heal the most grievous of wounds almost instantly.

Classified as Evolved Warriors, company scientists believe they are an evolutionary dead-end and once their metamorphosis has finished, it will change no more after that. It is theorized that their evolution is due to an immediate need that the hive requires, but not as a long term creation. Whatever the reasoning is behind these monsters, they should be engaged with extreme caution, as each one is different and there is no way to determine what capabilities it has until it has displayed them.[4]

A Subterranean Xenomorph

Subterranean Xenomorph (likely to be just a tunneling adaptation if not simply a previously unseen tunneling aptitude of Xenomorph Warriors)

Main article: Subterranean Xenomorph

The subterranean Xenomorph was a variation of Warrior that digs underground. It appears in the comic Alien vs Predator: Duel in Issue 1. These may just be normal warriors adapting to their enviroment, but it unclear at the moment.



The Prodos Games Alien Royal Guard model


Main article: Praetorian#Royal_Guard — Juvenile Praetorian
Essentially juvenile Praetorians, the previous developmental stage of a fully-fledged Praetorian is known as a Royal Guard. Whilst it is not known if these Xenomorphs develop in turn from a lesser caste or come about by some other process, it is known that they fulfill a similar role to that of Praetorians, that is; as their name would indicate; functioning as the guards of a Xenomorph hive's Queen.


Ravager by sl 8426-d92so7o

A Ravager from Aliens versus Predator: Extinction

Main article: Ravager

The Ravager is a Xenomorph caste, an evolved form of the Praetorian. Unlike other Xenomorphs, it is a hyper-aggressive killing machine with absolutely no interest in capturing victims alive to act as hosts for more Xenomorphs.

Ravager upgrade by sl 8426-d92spcz

A Colossal Ravager from Aliens versus Predator: Extinction

Heavy Phalanx
Main article: Ravager#Colossal Ravager
Ravagers can themselves further evolve into Colossal Ravagers, whereby they develop a hard chitinous shell that deflects even medium caliber weapons fire, as well as the ability to perform a rapid internal restorative process called regenesis. Regenesis causes a severely damaged Ravager to enter a regenerative cataleptic state instead of dying.
Carrier by sl 8426-d92so79

A Carrier from Aliens versus Predator: Extinction


Main article: Carrier
The Carrier spreads the Alien infestation to outlying regions by serving as a Facehugger transport. While riding a Carrier, Facehuggers do not expend energy, enabling them to reach farther areas than their limited energy supply would otherwise allow.
Carrier upgrade by sl 8426-d92soro

A Super Carrier from Aliens versus Predator: Extinction

Heavy Pontifex
Main article: Carrier#Super Carrier
When upgraded, Carriers develop the ability to hold 12 facehuggers instead of just 6. Upon death, their bodies explode apart, showering enemies with both painful acid and deadly facehuggers.



A War Empress from Aliens versus Predator: Extinction


Main article: Queen (caste)#War Empress

Some Xenomorph Queens have been known to evolve into tougher versions of themselves, known as War Empresses. Although they do not grow in size, their exoskeletal strength toughens significantly, thought to be by as much as 70% from it's original sturdiness, capable of deflecting all but the heaviest munitions.


An Empress from Aliens versus Predator: Extinction


Main article: Empress
An Empress is another caste of Xenomorph monarch, albeit larger and stronger than a Queen. Queens are, in fact, subordinate to them and they themselves are on Subordinate to a Queen Mother.

A Queen Mother

Queen Mother

Main article: Queen Mother

Queen Mothers, also known as Mother Queens,[5] are rulers of the Xenomorph species; even the Queens and Empresses are subordinate to them. Queen Mothers are protected by Palatines.


Palatines in Aliens: Female War.

Main article: Palatine

A Palatine is a Xenomorph that resembles a Queen-sized Praetorian or Drone. They are the Queen Mother's personal guard and are only native to Xenomorph Prime.

Auxiliary Xenomorph castes

This subsection contains what are best described as auxiliary Xenomorph castes (though perhaps feasibly, possible variations of one or more of the standard Xenomorph castes) that have only appeared in the expanded universe lore.


The Sideshow Collectibles Alien King


Main article: King (caste)

Among the largest, and most terrifying, biologics that an alien hive can bring to bear upon its enemies, is a creature dubbed the Monstrosity or 'King' Xenomorph. Towering several stories over its smaller brethren, this creature shakes the ground wherever it goes, causing small localized earthquakes in its wake. Near impervious to small arms fire, wounds dealt to it are regenerated almost instantly. It has been noted that when it eats its victims, its alien healing power actually speeds up, knitting even the most terrible wounds back together.

At range, it can project a huge ball of acid which if it hits even a target that is dug in, will melt them to little more than a puddle of matter. When it gets in close, it will unleash a screech, killing its initial enemies and then rush in with surprising speed for a creature of its size. Its gigantic claws and long tail are able to tear tanks and infantry to pieces in equal measure. Luckily, only a handful of such creatures found in the largest Xenomorph hives, has ever been catalogued by human scientists.[6]

2. Xenomorphs Spawned From Nonhuman Hosts

This section contains Xenomorphs spawned from nonhuman hosts (sentient extraterrestrials, sentient extradimensionals, supernatural beings and animals) that have appeared in the official media of the feature films and expanded universe lore.

Xenomorphs Spawned From Sentient Extraterrestrials



A Predalien


Main article: Predalien (caste)

The Predalien is a Xenomorph spawned from a Yautja, or Predator. It is apparently rare and is regarded by the Yautja themselves as an abomination and an affront to their species.[7] Predaliens feature many traits in common with Yautja, such as dreadlock-like appendages on their heads, similar mandibles, and occasionally comparable skin color and vocalizations. They are large, bulky creatures, possessing greater physical strength than both Predators and human-spawned Xenomorphs. Predaliens also have thicker tails than regular Xenomorphs. At least one Predalien has been capable of bypassing the Ovomorph/Facehugger reproductive cycle altogether, being able to implant multiple embryos within a single host directly through its inner jaw. This trait apparently allows the creature to build an army of Drones or Warriors before it becomes a mature Queen and enters its sedentary condition with an Egg sac. Predaliens notably take after their host to a greater extent than human-spawned Xenomorphs, possibly because the Predator's genetic code is significantly more potent. This could also explain why some Predaliens have been known to carry out ritualistic mutilation of their prey, perhaps as some form of instinctual throw-back to Yautja customs passed down genetically from the host.



Main article: Jockey-Xenomorph

The Jockey-Xenomorph, also known as the Ultramorph,[8] is a Xenomorph born from an Engineer (its name being a reference to the colloquial name for the Engineers, "Space Jockeys"). The Jockey-Xenomorph is usually depicted as being huge in size, perhaps rivalling Queens in height. The Jockey-Xenomorph should not be confused with the Deacon, a creature born from a Trilobite impregnating an Engineer.

Aliens: Apocalypse

Jockey Xenomorph from Aliens: Apocalypse

In the comic Aliens: Apocalypse a living Engineer is infected and its offspring is a huge Xenomorph that attacks normal human-spawned Xenomorphs on sight. A formidable creature, it manages to lay waste to a whole Hive. This version of the creature is no longer canon as the Engineers in Prometheus have been revealed to be vastly different from their depiction in the comics. However, the Xenomorph itself looks like a possible candidate to have come from an Engineer.
Aliens: Infestation

Jockey Xenomorph from Aliens: Infestation

In the Nintendo DS game Aliens: Infestation a Jockey Alien appears as the second boss of the game. Its appearance is considerably different from that seen in Apocalypse, as it possesses a trunk and clearly visible eyes. However, this is not what a Jockey Xenomorph would actually look like since, although the trunk was presumed to be part of the Space Jockey at first, Prometheus shows that it is part of a suit. It attacks by stomping, swiping and regurgitating large quantities of acid.

Xenomorphs Spawned From Animals



A Runner Chestburster


  • Scout Chestburster
Main article: Runner#Gestation
Unlike other Chestbursters, in Alien 3 the Runner is shown to be born fully formed and only needs to grow larger.[9] Why this is so is never explicitly stated. However, in the Special Edition, where the Alien is spawned from an ox, it is hinted that this could be a result of the Chestburster being unable to escape its host's chest cavity at the typical interval (likely due to its higher structural rigidity), as the ox dies some time before the Chestburster hatches. Furthermore, the Special Edition Chestburster is considerably larger than a typical specimen when it finally emerges from the corpse, indicating it had already begun maturing within.[10]
Runner 2

A Runner

  • Scout
Main article: Runner

The Runner, also known as the Dog Alien or Ox Alien, is an adult form of the species Xenomorph XX121 spawned from a quadrupedal host animal (such as a dog). Runners, as their name implies, are fast and agile, and can spit acid from their mouths. Runners have variously been portrayed as being slightly larger and slightly smaller than typical human-spawned Aliens, differences that no doubt derive from the animal that hosted the creature. However, the Runner in Alien3 is around 7 feet 5 inches tall when standing on its hind legs.

  •  ?Cystic Runner

A Crusher

Quadruped — Praetorian

  • Aries — Praetorian Runner
Main article: Crusher
The Crusher, also known as the Charger, is a Xenomorph caste that was encountered by Colonial Marines from the USS Sephora on Acheron (LV-426). Its most notable features are its large head crest, which is said to be completely bulletproof, and its habit of charging its prey to inflict massive blunt force trauma. It acts as something of a heavy unit for the Xenomorphs, able to engage even armored vehicles with some success.
Runner Queen

A Runner Queen

Quadruped — Queen

  • Runner Queen
Main article: Dog Queen
The Dog Queen is a Xenomorph that appears in the Alien3 video game released on the Super Nintendo Entertainment System. They are essentially a Queen grown from a Runner Alien, looking similar but considerably larger. They spit clouds of acid smoke and live on the surface of the planet Fiorina "Fury" 161.

One of the Maru's Demons

Various terrestrial animals (PCW9512)

  • Maru's Demons
Main article: Maru's Demons
The Maru's Demons are similar to Xenomorph XX121 (Alien) in most ways. Standard elongated chrome head piece, tall, dorsal plates running up the spine, and six fingers on each hand. Despite this they are brown in color, have a rather elongated chin, and very awkward tail, often seen swinging about with little control. Perhaps due the more feral species on the planet.

Xenomorph (LV-223)

Various terrestrial animals (LV-223)

  • Xenomorph (LV-223)
Main article: Xenomorph (LV-223)
On LV-223 a variety of different Xenomorphs became present on the moon due to a multitude of hosts for impregnation as well as possibly the presence of the Chemical A0-3959X.91 – 15, that began mutating the creatures. Most notable specimens were the ones that possess their usual dome heads but with the back splits off and what almost seems to be eyes. Additionally, the hive's Queen had a different head crest to normal ones.

The Bull Alien as seen in the Kenner comics


  • Bull Alien
Main article: Bull Alien

The Bull Alien is a part of the Aliens toy line produced by Kenner Products. The Bull Alien is spawned from cattle hosts and has two horns on its head, and is very quick (able to outrun Stinger XT-37s) and powerful. This large Xenomorph variant can knock down military vehicles by rushing in. It is also very durable, capable of taking a rocket to the face without even flinching. Only fire seems to kill them.[citation needed] Bull Aliens commonly operate in herds, another trait they inherit from their host.


A Rhino Alien


  • Rhino Alien
Main article: Rhino Alien

The Rhino Alien is a large Xenomorph variant, created when a Facehugger impregnates a rhinoceros or a similiar creature (like rhynth).[citation needed] Like its host, it sports a muscular stature, as well as a pair of large horns which it presumably uses as a means of attack or defense.


  • Snatcher
Main article: Snatcher

A Snatcher was the adult form of a Xenomorph born from a Chimpanzee. Due to the DNA Reflex, the snatcher has the characteristics of its host, namely its posture and proportions. The Snatcher is quadrupedal (?knuckle-walking) and is capable of catching up to even the most fittest of humans in a sprint.

Appearing in the Aliens: Space Marines comics on the planet Zeevan, the Space Marines also encountered a Queen Gorilla Alien that had retained the tetrabrachial physiology (technically making it semi-hexabrachial because of the pair of smaller ventrally positioned arms featured on Xenomorph Queens) of the host species (whilst the lesser caste only had two arms).

Blue Moon centipede (giant extraterrestrial centipede species)

Main article: Darkness Falls

A species of giant extraterrestrial centipedes that were introduced to the planet Oleta were hosts for Xenomorphs that spawned large multilegged centipede-like Xenomorphs that were incredibly dangerous. It was found that flamethrowers were only moderately effective against them, though the DNA reflex caused them to also inherit the host species' susceptibility to salt, violently reacting to it and breaking them down on contact.

On LV-223 a variety of different Xenomorphs became present on the moon due to a multitude of hosts for impregnation as well as possibly the presence of the Chemical A0-3959X.91 – 15, that began mutating the creatures. Most notable specimens were the ones that possess their usual dome heads but with the back splits off and what almost seems to be eyes as well as winged flight capable Xenomorphs. Additionally, the hive's Queen had a different head crest to normal ones.


A Flying Queen

Winged animal — Queen

  • Flying Queen
Main article: Flying Queen

The Flying Queen is a part of the k in color toy line produced by Kenner Products. The Queen Xenomorph was black in coloration, with large avian-like talons used for snatching prey as this monster swoops. Unlike most Xenomorphs, she had membraned wings and a membraned tail like a bat and her crest had a row of blunted spikes running down their length.

Winged animal — Empress

  • Giant flying Xenomorph Queen

Due to its size, the giant flying Xenomorph Queen is likely a Xenomorph Empress or possibly spawned from a giant flying creature, it is encountered in Aliens: Armageddon.

(Unspecified habitat)

(Possibly a large marine vertebrate)

  • Giant Chestburster

The giant Chestburster is possibly spawned from a species of large marine vertebrate and is encountered in Aliens: Armageddon.

3. Altered Xenomorph Varieties

This section contains the various mutant Xenomorphs, genetically engineered Xenomorphs, hybrid/tribrid Xenomorphs, cyborg Xenomorphs as well as fundamentally distinct Xenomorphs and Xenomorphs of unknown conception that have appeared in the official media of the feature films and expanded universe lore.

Mutant Xenomorphs

This subsection contains Xenomorph varieties that are mutated by either natural or unnatural means but without the intent to do so (except for the Newborn, though that was only come about due to an unintentional mutation in the Cloned Queen from the cloning process involved in her creation) by either the Xenomorph Queen or genetic scientists involved.

Naturally occurring mutations

This section contains Xenomorphs that had become mutated presumably by way of spontaneous natural mutation.

Red Xenomorph warriors

Red Xenomorphs

Main article: Red Xenomorph
The Red Xenomorphs of Xenomorph Prime were a natural mutation and faction of rebel Xenomorphs that had defied and opposed the original black colored xenomorphs. The two sides eventually waged war against each other.
Pink Ovomorph

Pink Ovomorph

Pink Ovomorph

Main article: Ovomorph (Egg)#Pink Ovomorph
The pink ovomorph was found amongst an ordinary clutch, though the origins of such eggs are unknown. It was this irregularly coloured pink egg that hatched the facehugger that spawned mutant Chestburster known as the Bodyburster which resembles a large black Chestburster.

The Mutated Chestburster AKA Bodyburster


Main article: Bodyburster

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

Genetically Engineered Xenomorphs

This section contains Xenomorph varieties produced by genetic scientists usually for the purpose of controlling (Spliced Xenomorphs) and therefore weaponizing them, but also to create varieties with new capabilities like the Spitter and Boiler that aren't necessarily human controlled (or weren't yet at the latest known stage of their development).

Spliced Xenomorphs (weaponized)

Main article: Spliced Xenomorph

Spliced Xenomorphs are an alteration from the highly aggressive, highly predatory standard Xenomorph. To make them more manageable, their DNA has been spliced with more docile, less predatory creatures. Alternatively, their DNA can be spliced with more aggressive, highly predatory creatures, with the intention of both weaponizing and mobilizing these creatures.

AVP kseries1

A K-Series Xenomorph warrior


Main article: K-Series

The K-Series (Kadinsky-Series) were a genetically engineered breed of Xenomorphs created by the scientist Dr. Samuel Kadinsky. They were designed to be superior, but whenever the races went head to head, the original strain won out every time.

Predalien Queen

Main article: Predalien Queen

(As seen below in Hybrid/Tribrid Xenomorphs)

General Bush's engineered Xenomorphs

Appearing in Alien vs. Predator (1994 arcade game) were several varieties of Xenomorphs that are heavily implied to have been genetically engineered by General Bushes scientists working together with Weyland-Yutani with the intent to develop them as bioweapons.


Main article: Defender
Defenders are a strong type of Drone-like Xenomorph that can actually deflect the strongest of ammunitions with its carapace, wrists and probably legs. Those body parts possess very strong and thick chitinous armour which makes it an obvious danger.

A Smasher


Main article: Smasher
The Smasher appears to be a special type of a Xenomorph warrior. It's brownish-green, and its carapace has a smooth side, which is lighter coloured. Smashers; as their name implies; smash into their foes. They move similarly to any other warrior, just moving bipedally more than quadrupedally like standard warriors.
Arachnoid - 2

NECA's new Arachnoid design


Main article: Arachnoid

The Arachnoid is a greyish colored Xenomorph variant which adapted significantly stronger leg muscles, allowing them to jump higher and move faster.

Chrysalis - 4

NECA's new Chrysalis design


Main article: Chrysalis

The Chrysalis is a very large Xenomorph around the same size as a Praetorian with a greyish-green exoskeleton and a hard, tan carapace on its head, back and forearms. The Chrysalis sometimes moves/attacks by rolling itself on the ground in a ball before proceeding along the ground and its head actually extends a short distance from underneath the carapace over its head when delivering a headbite, in addition to the extension of the inner jaw.

Razor Claws

NECA's new Razor Claws design

Razor Claws

Main article: Razor Claws
Razor Claws are a large breed of Xenomorph with a purple coloration and large, sharp claws on its fingers. It is known for its unusually great speed for its size, making it hard to defeat or even keep up with.


The flying octopodal Queen

Grant Corporation Station 13's engineered Xenomorphs

Flying octopodal Queen

The flying octopodal Queen in the following image was most likely genetically engineered at Grant Corporation Station 13 instead of being spawned from a winged hexapodal (six limbed) creature with two arms, two legs and two wings.

Hybrid/Tribrid Xenomorphs

This section contains Xenomorph varieties that are usually genetically engineered but are significantly hybridized with one or two (tribridized) other species, usually with the intent to control and therefore weaponize them.

The Rogue

The Rogue

Main article: Rogue (Xenomorph)

The Rogue was the final product of the gene splicing experiments being carried out by Professor Kleist at Charon Base under Project Chimera. Although Kleist had achieved significant success genetically engineering tame Warrior hybrids, he encountered severe setbacks when attempting to create a hybrid Queen, including many attempts that were born horribly deformed, eventually perishing as a result of their mutations.[11] The breakthrough came when Kleist incorporated human DNA in the hybridization process, using genetic material taken from John Cray. The result was the Rogue, an enormous and hugely powerful male Xenomorph "king" that it was hoped would act as a tame counterpart to naturally-occurring Queens.

Kleist's insistence that the Rogue would be tame appeared vindicated when it refrained from harming Cray, who was placed in the creature's cell stripped and bound to a chair. However, the truth behind the Rogue's nature was revealed when several natural Xenomorph Warriors were also let into the containment chamber; far from being docile or exerting some form of calming control over the Warriors, the Rogue flew into a rage and savagely attacked them, effortlessly tearing them to pieces. This led to Kleist concluding that the only reason the Rogue ignored Cray was because he posed no threat.
Predalien Queen (0)-0

The Predalien Queen

Predalien Queen

Main article: Predalien Queen

The Predalien Queen was Dr. Kadinsky's second creation after the K-Series Xenomorphs and because it was apparently impossible for a Predalien Queen to exist, the creature was created via bio-engineering. Because of this, the Predalien Queen can be considered an actual hybrid unlike other predaliens and due to it being unnatural as it seems to have been a queen that was experimented on with Yautja DNA rather than the typical result of the life cycle process that allows embryos to take on its host's characteristics.
