Xenomorph XX121
Known by a variety of names, the horrifically bizarre alien Xenomorph XX121 is an endoparasitic lifeform with a unique life cycle. The alien shifts from egg to parasitic Facehugger to embryonic Chestburster to adult creature and beyond before beginning the cycle anew. While it has been classified inaccurately as either Invictus raptus or Linguafaeda acheronis by the few in the scientific community to have observed the alien and survived, recent research seems to indicate that Xenomorph XX121 is actually comprised of two separate species—the Facehugger (Manumala noxhydria) that inseminates a host, and the rapidly maturing Chestburster creature (Plagiarus praepotens) that results from that act—both operating together in a symbiotic relationship. Allegedly blind, the alien still has keen senses and can detect even the slightest movement. These biomechanoid creatures shed their cells and replace them with polarized silicon, essentially growing their own refractive armor. They have highly caustic concentrated acid for blood and deadly prehensile tails. Immensely strong in their adult forms, a Plagiarus Drone or Soldier can easily lift a man by the head and crush his skull in its hands.
As to their origins, no one can be certain. Some believe them to be biological weapons created by some bygone race, possibly the enigmatic and godlike Engineers, while others believe they are a naturally evolved species that the Engineers themselves worshipped. Some religious cults take that a step further, believing the aliens were sent here by God or gods to exact divine retribution on humanity for leaving our solar system and daring to enter the heavens. Still others believe that humanity had a hand in the creatures’ creation, and that they are a corporate experiment run amok. What is for certain is that they are dangerous to everyone. They are a parasitic plague that is working its way across the Frontier, and Weyland-Yutani, as well as other corporations, want to find a way to control and weaponize them for profit.
Stage I: Ovomorph (Egg). Large leathery objects, Ovomorphs are the beginning of the alien life cycle. They come in various sizes from 2 to 4 feet tall. While most open with four petals at the top, some only have a single slit that opens to reveal the Facehugger it carries within. These eggs are lifeforms in their own right, able to protect their precious cargo from blunt trauma and forced entry, while also sensing movement and awakening the parasite within accordingly. Naturally occurring alien eggs are generated in one of two forms—either they are the result of a transformation perpetrated on a living host, causing it to metamorphose into an Ovomorph, or they are simply birthed by a Queen. Queen produced eggs are hardier and healthier than those produced through ovomorphing.
Stage II: Facehugger. Manumala noxhydria is a parasitic form of Xenomorph designed for one task only—the implantation of Plagiarus bacteria within a living host. Coming in a variety of sickly yellowish to brown flesh tones, a Facehugger has a small body, eight spider or crab-like fingers, two large breathing sacks, and a long and powerful tail which it uses to spring itself onto a startled host’s face. The Facehugger clutches its fingers around the victim's head, wraps its tail around their throat, and emits an anesthetic that renders the host unconscious, before inserting its proboscis down the creature’s throat. There are several different Facehugger types which appear to vary only slightly in appearance. The major difference is the type of seed they carry—be it for a Praetomorph, Xenomorph Drone, or Queen.
Stage III: Chestburster, Bambi-Burster, Imp. The alien grows within the host animal’s chest, reaching a point of maturity where it is no longer dependent on the host for survival. While most hosts feel sick to their stomach as the parasite grows within them, some comment that they feel better than they have in ages. As the organs of the host are transformed into the embryonic alien, the host’s ribcage is also softened to a point where the Chestburster can perform the act after which it is named. Gestation complete, the creature erupts from the host, killing it from a combination of massive tissue damage, blood loss, and organ transformation. A newly birthed alien exhibits different traits depending on its type.
Chestburster. Jaundiced beige in color, the snake-like Chestburster has a mouth full of metallic canines. Depending on the length of gestation, a Chestburster will either be born with tiny arms or stubs where the arms will eventually grow in.
Bambi-Burster. Otherwise similar to the Chestburster, this fawn-like creature is the result of an alien embryo developing within a quadrupedal host. As animals generally mature at a faster rate than humans, the Bambi-burster is birthed with four spindly legs that it uses to propel itself at great speeds.
Imp. The immature form of a Praetomorph, the Imp has translucent skin, a carapace and rawboned features that make it look very much like a miniature version of its adult form. If an Imp doesn’t feel threatened upon emergence, it will sometimes mimic the actions of the nearest creature. Like all Praetomorph stages, Imps mature at a substantially faster rate than traditional Chestbursters.
Queenburster. An embryonic queen, the Stage III Xenomorph nicknamed the Queenburster gestates over days instead of hours. When born, the creature has a partially formed crest on its head, both sets of arms, and fully developed legs.
Stage IV: Stalker, Scout, Drone. Now young adults, Stage IV Xenos are able to adapt a bipedal stance, even though they might not always make use of it. Their now fully polarized skin is near black in tone; they have a bladed prehensile tail, six-fingered hands with enlarged nails, pronounced ribs, and translucent to opaque smooth-domed heads. In addition to their metallic, toothy mouths, they have an inner set of jaws that can strike like a piston—a favored mode of attack.
Save for the Scout, Stage IV Xenomorphs have four dorsal tubes affixed to their backs. While some have theorized the tubes are used for spinning and cocooning the resin for their hive, that has generally been discounted as a fallacy. The current line of thinking is that the tubes are a type of breathing apparatus, filtering out airborne toxins and allowing the creatures to breath underwater. However, as Aliens have been observed surviving in the vacuum of space, it is possible that they do not need to breathe at all.
Stalker (Praetomorph). Averaging about 9 feet tall and comfortable moving on two legs as well as all four, Stalkers are the highly aggressive adult form of the Praetomorph. Classified as Plagiarus linesteres, the Praetomorph is a variant breed of Xenomorph XX121. The Stalker is believed to be an evolutionary dead end for the Praetomorph, as no encountered specimen has ever metamorphosed further. Unlike its phylogenetic relative P. praepotens, the P. linesteres does not appear to have a Queen stage. It also differs in that it has no biomechanical endoskeleton, and its teeth are translucent bone instead of metal. They are bigger, more powerful, resilient, and more resistant to fire than standard Xenos—they just happen to be less intelligent and more animalistic in nature.
Scout (Runner). 7 feet tall when standing upright, the brown-black Scout or Runner is a particularly fast adaptation of P. praepotens. Usually moving about on all fours, the Scout’s job is to seek out a nearby source of hosts and alert the hive when one is found. If no hive yet exists, the scout will begin capturing hosts and cocooning them for ovomorphing until a Queenburster is produced. Once the Queen is birthed and a hive location is secure, a Scout will metamorphose to its next stage. For reasons unknown, Scouts have no dorsal tubes—they do not develop them until Stage V.
Drone. Sometimes called Lurkers, Drones stand 8 feet tall, and are stealthy ambush hunters. Their tails end in a deadly hooked blade and rudimentary barb for Ovomorph injection. In many ways, Drones are the most alien of the species. It is theorized that the strange behavior often exhibited by Drones is due to them reaching young adulthood without establishing a connection to the alien hive mind. The stealthy creatures’ fluid yet awkward movements and unorthodox reactions to stimuli belie their methodical intelligence. As much as a Stalker acts like a feral animal, a Drone plots. The ebon Drone is a clever yet single-minded iteration of the Xenomorph. Development of P. praepotens will arrest at Stage IV unless a Queen’s pheromones cause it to molt into a Worker or Soldier—whichever form the hive is most in need of. Until then it will eat, gather hosts for ovomorphing, and sleep. When it evolves to the next stage, it joins the hive mind.
Stage V: Soldier, Worker, Sentry. As the hive mind takes a hold of them at Stage V of their development, P. praepotens molt to assume specialized roles within their community.
Soldier (Warrior). Romantically referred to as a Warrior, a Soldier Xenomorph is the adult form of a Drone. As the alien matures, the creature’s dome loses its form and melds with the ridged tissues beneath it. The alien’s head begins to polarize and harden, forming an armored carapace. Blades will begin to grow from the Xeno’s elbows, and its hands will mutate into five-fingered claws, dropping the sixth digit. Blue-black in color, Soldiers are nimble and attack en masse. The Soldier’s tail has a barb at the end with a toxin that can cause paralysis in most known lifeforms. Once incapacitated, the Soldier will carry its prey back to the hive to be impregnated by a Facehugger.
Worker. The diminutive Workers build and maintain the hive. Also called Weavers, they produce and spin the resin of the hive with their long proboscis tongues, shape it with their hands and feet, position eggs near cocooned hosts, and feed and maintain the Queen. Physically, they are somewhat different than the other members of P. praepotens. Transformation from Drone to Worker will see an alien shrink to between 4 and 6 feet in height. Its skin will turn a sickly grayish white, while its tongue grows pink, elongates, and develops a funnel through which it will secrete the makings of the hive. Workers ignore threats within the hive and will run if threatened, leaving their protection to Soldiers and Sentries.
Sentry. After Scouts have secured a hive and a source of hosts, they mature into Sentries. Like Soldiers, their carapaces become ridged and armored. They are still incredibly fast and dexterous, with specialized gripping hands and feet that allow them to scale walls and ceilings with greater efficiency than other Xenos. Attuned to their Queen’s needs, they will back off or attack as she signals. Also called Defenders, Sentries will not hesitate to sacrifice themselves to keep hive invaders at bay and protect their Queen. The Sentry uses the Xenomorph Runner statblock but with an AC of 18.
Stage VI: Praetorian, Charger, Queen. Stage VI P. praepotens are monstrous horrors. Their immense size and crested carapaces mark them as the leaders of their hive. Stronger and smarter than those beneath them, Stage VI Xenos command alien armies. These Stages are only reached when an existing Queen produces royal jelly and exposes her Soldiers and Sentries to it.
Praetorian. When a hive reaches a population of over 300 individuals, Workers feed the Queen’s chosen warriors with Royal Jelly until the transformation to Praetorian takes place. The penultimate form of an alien Soldier, Praetorians grow up to twice the height of their brethren. They develop a head crest similar to a Queen’s, but maintain a more standardized bipedal form with only two arms. Lead protectors of the hive, Praetorians are the Queen’s Royal Guards and army commanders. It is theorized that if a hive loses its Queen, a Praetorian can molt into a new one. If this happened before another hive invaded, the old hive can be preserved. If not, the invaders take advantage of the leaderless Xenos and claims them for their own Queen.
Charger (Crusher). Also called the Crusher, the Charger is the Xenomorph equivalent of a tank. After being force-fed Royal Jelly and raw metals by the Queen’s workers for weeks, a bloated Sentry will cocoon itself in resin and undergo a massive transformation. Its quadrupedal stance is bulked up and its head grows a massive, armored chitinous crest similar to a Queen’s. Chargers grow to stand between 6 to 10 feet tall at the shoulder. Heavy defensive protectors of the hive, the Crusher will charge an enemy like a rabid rhino, trampling personnel and plowing through even lightly armored vehicles. Essentially the Runner variant of the Praetorian, the Charger’s mobility is limited in that it cannot climb or jump very well. Luckily, they are relatively rare and only appear in long established hives.
Queen. The mother of the hive, at 20 feet tall or more, the alien Queen is perhaps the strongest and most intelligent of the species. While any adult alien is capable of initiating ovomorphing in a host organism, only Queens have the ability to lay eggs en masse. When her first molt is completed and the Queen is fertile, her Workers spin a resin cradle that holds her suspended above the floor of the hive. The Queen then grows an enormous egg sac that soon becomes distended and engorged with developing eggs. As each new Ovomorph is ready, she deposits it on the ground via ovipositor for her Workers to spirit away to nearby cocooned hosts.
The most astonishing thing about the Queen is her ability to communicate with her hive. While evidence exists to suggest she does so via a combination of pheromones and subsonic vocalizations, there are company consultants who believe she communicates telepathically as well, “speaking” with her children over immeasurable distances. In fact, corporate psychiatrists have documented that employees who score high on their company esper tests and find themselves within the proximity of an alien hive will have vivid dreams of the Queen calling to them, whether they are aware of her existence or not.
Additionally, professional dreamers seem to have a hard time producing after being exposed to an alien Queen. Of course, this could simply be a form of PTSD, but it bears further investigation. An alien Queen’s distinguishing characteristics include her size, her large crested head, set of six dorsal spikes (instead of tubes), unique stance and a second set of grasping arms.
Ovomorph
Hazard
An ovomorph is a Small Object (AC 10; 14 hit points; vulnerability to fire damage; resistance to cold damage; immunity to acid and poison damage). When the ovomorph is destroyed, it explodes in a burst of acid. Each creature within 5 feet of it must make a DC 10 Dexterity saving throw, taking 7 (2d6) acid damage on a failed save, or half as much damage on a successful one.
A creature that isn't a Construct, Undead, neomorph or xenomorph that moves anywhere within 5 feet of an undisturbed ovomorph without first making a DC 16 Dexterity (Stealth or Sleight of Hand, as determined by the GM) check to move subtly, disturbs it.
When an ovomorph is disturbed, it opens like a flower and a facehugger immediately leaps out and attempts to make a Cling attack against the creature that disturbed the ovomorph. Once an ovomorph releases its facehugger it becomes inert.
There is a 15 percent chance that the ovomorph is mutated. A mutated ovomorph is pink in colouration, and a xenomorph embryo implanted by it's facehugger forms into a goreburster. A host carrying a goreburster embryo has it's speed halved after 3 hours of gestation.

Actions
Cling. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 3 (1d4 + 1) bludgeoning damage, and the facehugger attaches to the target. While attached, the facehugger can’t make Cling attacks. The facehugger can detach itself by spending 5 feet of its movement. As an action, a creature within reach of the facehugger can try to detach it, doing so with a successful DC 20 Strength check. The creature the facehugger is attached to takes 21 (6d6) slashing damage if it successfully removes the facehugger or if it tries and fails.
Impregnate. The facehugger wraps itself around the face of a creature it is attached to, and the creature falls unconscious, remaining unconscious for as long as the facehugger is attached. The facehugger remains attached to the creature for 12 hours, implanting its host with a xenomorph embryo. After the 12 hour period, the facehugger detaches itself and the creature regains consciousness. The facehugger then dies in 1d4 rounds.
A Humanoid or Beast host can carry only one xenomorph embryo to term at a time. Over 7 hours, the embryo gestates in the host’s chest cavity and forms a chestburster. One round before giving birth, the creature starts to seizure, coughing up blood. During this time, the creature is incapacitated. At birth, the chestburster bursts through the creature’s ribcage in 1 round, killing the host in the process.
If any effect that cures disease is used on the creature before the chestburster’s emergence, it must succeed on a DC 18 Constitution saving throw. On a successful save, the unborn xenomorph is disintegrated.Bonus Actions
Leap. The facehugger leaps up to 20 feet in any direction, provided its speed isn't 0. This movement doesn't provoke opportunity attacks.

Acidic Blood. When the chestburster takes bludgeoning, piercing or slashing damage, each creature within 5 feet of the chestburster takes 5 (2d4) acid damage.
Cocoon. The chestburster can form a cocoon around itself over the course of 10 minutes. The cocoon is a Small Object (AC 16; 50 hit points; vulnerability to fire damage; immunity to acid, cold, poison, and psychic damage). When the cocoon takes bludgeoning, piercing or slashing damage, each creature within 5 feet of the cocoon takes 10 (3d6) acid damage. The chestburster can exit or enter the cocoon using 5 feet of movement.
While within the cocoon, the chestburster has total cover against attacks and other effects outside the cocoon, but its blindsight isn't blocked by the cocoon.If the chestburster spends 6 consecutive hours within the cocoon, the cocoon becomes Medium, and the chestburster matures into a xenomorph drone.
After maturing, the drone is incapacitated for 1 minute, or until it takes damage. If the drone remains in the cocoon after the incapacitated condition ends, it can make Tail attacks against creature's within its reach. The drone can exit the cocoon by using half its movement, landing prone, and must use its action and bonus action to unfurl its limbs before it can stand up.Echolocation. The chestburster can’t use its blindsight while deafened.
Heat Dampening. The chestburster cannot be seen or detected by thermalsight.
Slippery. The chestburster has advantage on ability checks and saving throws made to escape a grapple, and creatures have disadvantage on attacks against it.

Actions
Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 4 (1d4 + 2) piercing damage.
Terrorizing Hiss. The chestburster flashes its razor sharp teeth and hisses malevolently at one creature it can see within 30 feet of it. If the target can see and hear it, the target must succeed on a DC 12 Wisdom saving throw or be frightened of the chestburster until the end of it's next turn.
Bonus Actions
Slithering Escape. The chestburster takes the Disengage or Hide action.

When a creature that can see the bodyburster's eyes starts its turn within 30 feet of the bodyburster, the bodyburster can force it to make a DC 17 Wisdom saving throw if the bodyburster isn't incapacitated and can see the creature. A creature that fails the save is stunned until the start of its next turn.
Unless surprised, a creature can avert its eyes at the start of its turn to avoid the saving throw. If the creature does so, it can't see the bodyburster until the start of its next turn, when it can avert its eyes again.

While infected, the target becomes host to a bodyburster and can't regain hit points, and its hit point maximum is reduced by 10 (3d6) every 2 hours. If the disease reduces the target's hit point maximum to 0, the bodyburster bursts out of the host's body in 1 round, killing the host in the process and destroying their body. If any effect that cures disease is used on the creature before the bodyburster’s emergence, it must succeed on a DC 18 Constitution saving throw. On a successful save, the disease is cured.
Claws. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 10 (2d4 + 5) slashing damage, and the target is grappled (escape DC 15) if it is Medium or smaller. While the target is grappled, the bodyburster can make an Inner Jaw attack or use Skull Crush against it as a bonus action.

Any non-xenomorph creature that enters the trail, starts its turn there, touches the goreburster, hits it with a melee attack while within 5 feet of it, or is hit by an attack from it must make a DC 17 Constitution saving throw against disease. On a failure, the target takes 9 (2d8) necrotic damage and is infected with goreburster slime. Every 10 minutes that elapse, the creature must repeat
the saving throw, reducing its hit point maximum by 11 (2d1O) on a failure. This reduction lasts until the disease is cured. If the disease reduces the target's hit point maximum to 0, its body violently explodes in a shower of gore, each non-xenomorph creature within 10 feet of an exploding creature must succeed a DC 17 Constitution saving throw or also be infected. The disease can only be cured by gaining a level of irradiated while infected.

Each time the goreburster hits the wounded target with this attack, the damage dealt by the wound increases by 10 (3d6). Any creature can take an action to stanch the wound with a successful DC 12 Wisdom (Medicine) check. The wound also closes if the target receives magical healing.
Terrorizing Hiss. The goreburster flashes its razor sharp teeth and hisses malevolently at one creature it can see within 30 feet of it. If the target can see and hear it, the target must succeed on a DC 14 Wisdom saving throw or be frightened of the goreburster until the end of it's next turn.

Actions
Multiattack. The xenowing makes one Claw attack and one Tail attack.
Claws. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 9 (2d4 + 4) slashing damage, and the target is grappled (escape DC 17) if it is Medium or smaller. Until this grapple ends, the xenowing can't use its Claw attack on another target, and when it moves, it can drag the grappled creature with it, without the xenowing's speed being halved. While the target is grappled, the xenowing can make an Inner Jaw attack against it as a bonus action.
Inner Jaw. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 10 (1d12 + 4) piercing damage. This attack scores a critical hit on a roll of 17 to 20 and rolls the damage dice of a crit three times, instead of twice.
Tail. Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 14 (3d6 + 4) piercing damage.
Impregnating Sting (1/Day). Melee Weapon Attack: +9 to hit, reach 10 ft., one creature that is grappled by the xenowing, incapacitated, or restrained.. Hit: 14 (3d6 + 4) piercing damage. If the target is a Humanoid or Beast, it must succeed on a DC 17 Constitution saving throw or be infected with a disease—a minuscule xenowing egg.
A host can carry only one xenowing egg to term at a time. Over six hours, the egg moves to the chest cavity, gestates, and forms a chestburster (with a 30 foot flying speed). In the 12-hour period before giving birth, the host starts to feel unwell, its speed is halved, and it has disadvantage on attack rolls, ability checks, and saving throws. At birth, the chestburster chews its way through vital organs and out of the host's chest in 1 round, killing the host in the process.
If any effect that cures disease is used on the creature before the chestburster’s emergence, it must succeed on a DC 18 Constitution saving throw. On a successful save, the unborn chestburster is disintegrated.Bonus Actions
Nimble Escape. The xenowing takes the Disengage or Hide action.

Claws. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 9 (2d4 + 4) slashing damage plus 9 (2d8) radiant damage. Instead of dealing damage, the biomorph can grapple the target (escape DC 14) if it is Medium or smaller. Until this grapple ends, the biomorph can't make Claw attacks, and the target takes 17 (3d8 + 4) bludgeoning damage plus 9 (2d8) radiant damage at the start of each of its turns. A creature
reduced to 0 hit points by this damage dies as the biomorph tears its head off. Additionally, while the target is grappled, the biomorph can make a Vampire Spike attack against it as a bonus action.
Tail. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 14 (3d6 + 4) piercing or slashing damage (biomorph's choice).
Vampire Spike. Melee Weapon Attack: +8 to hit, reach 5 ft., one creature grappled by the biomorph.

Each creature in a 10-foot-radius sphere centered on the biomorph must make a DC 16 Dexterity saving throw. On a failed save, a creature takes 28 (8d6) acid damage and it is covered in acid. A creature covered in acid takes 14 (4d6) acid damage at the start of each of its turns until it or another creature uses its action to scrape or wash off the acid that covers it. On a successful save, a creature takes half as much damage and isn't covered in acid. Additionally, the biomorph's size becomes Small for 1 minute, and it immediately takes the Disengage action and moves up to its speed. While it is Small, the biomorph can move through any opening at least 1 foot wide without squeezing. It can also squeeze to fit into a space that a Tiny creature could fit in.
