Alien

The Alien, known for the film franchise of the same name, is a playable guest character in Mortal Kombat X.

About the Alien
The Alien, or officially known as Xenomorph XX121, is the primary antagonistic species of the Alien film franchise.

The Alien is a recurring major threat, and while its exact characteristics and appearance change between movies, it remains one of the most dangerous creatures in the known universe.

The Xenomorph's life-cycle is arguably their most iconic feature; they start life as an egg (or Ovomorph) laid by the monstrous Queen. When a living being that isn't one of their own comes into physical contact or close range within the egg's radius, it will "hatch" and reveal the spider-like Facehugger. The Facehugger's purpose is to attach itself to the victim's face and orally transmit a Xenomorph embryo down the victim's throat. The victim remains in a comatose state during the process, which can take several hours - once the process is complete, the Facehugger will detach itself and die. Gestation of the embryo is usually incredibly quick, ranging from a few hours to a day for it to fully develop.

Once the new Alien is ready to hatch, it will violently force itself through the host's rib cage and tear itself out of their chest (which has led to this stage being called a Chestburster). The larval Alien promptly flees from its host and seeks out a safe hiding spot as it rapidly molts into a fully-grown Xenomorph. The resulting adult can take on a variety of unique forms, depending on the species it was incubated in.

Xenomorphs are immensely hostile and aggressive towards other life-forms. In most cases, they will either immediately attack other creatures on sight or take them to their nest for harvesting, but they may also stalk their prey for a time in order to ambush them later. Life-forms that are not suitable for harvest are generally ignored. The entire Xenomorph species lives to propagate itself by using any lifeforms in whatever ecosystem they've infected to grow their numbers and spread even further. Every nest usually contains a Queen that will instruct the other Xenomorphs on their duties, acting somewhat like a hive mind - larger nests may also include Praetorians, advanced Alien variants that protect the nest from intruders. Regardless, they are still able to function without a Queen.

Aliens are also known for their constant association with the Yautja species (better known as Predators). The latter views the Aliens as the "ultimate prey"; those few hunters who survive encounters with the Xenomorphs receive great praise from fellow Predators.

In Mortal Kombat X, a Xenomorph is depicted being born from Baraka, creating a new, and exclusively unique variation of the Alien.

Appearance
The Alien retains its standard bio-mechanical skeletal appearance carried over from its namesake series, retaining the black chitinous hide, ribbed sides, double-fingers, inner-jaws, and segmented tail with barbed tip, but also possesses several noticeable differences from the classic look of the creature.

The Alien is much bulkier in comparison to the leaner figure of the standard Drone and Warrior castes of the film series, with the tube like protrusions emerging from its back being much shorter than normal. The elongated cylindrical skull is also much shorter, almost spherical, and the Alien possesses more exposed fanged teeth along its mouth, one of the more obvious inheritances it takes up from its Tarkatan host, including Baraka's cheek spikes.

The most obvious physical distinction this Alien has when compared to its film counterparts are the ridged 'sheathes' along its forearms that hold its Tarkatan Blades. Unlike the smooth, sword-like standard Tarkatan Blades, the Alien's are segmented like its tail and have the same dark coloring of its chitinous hide. While the head of the Alien has been depicted as the smooth style of the original Drone caste, its Tarkatan variation gives it the ridged head of the Warrior caste and its Konjurer variant gives it the larger crest of a Praetorian.

Biography

 * Mortal Kombat X: The Xenomorphs had descended on Outworld long ago, but the dormant eggs they left behind were only recently found. The leader of the Tarkatan patrol had picked up one of the leathery orbs, only to have it burst open and its occupant latch itself to his face. Later, after the "facehugger" had fallen off, the Alien progeny burst from the unfortunate Tarkatan's chest, bearing characteristics of both Xenomorph and host. It eluded the rest of the Tarkatan soldiers and eventually killed them. The creature now roams Outworld, looking for more hosts. Its amazing strength and animal fury make Alien almost unstoppable.

Powers and abilities
Xenomorphs are structurally superior to most other lifeforms. They possess great strength, speed and agility, the ability to stick to walls, a cunning intelligence, and most notably, highly corrosive blood, giving them an incredible defense mechanism. These traits have led many to identify the species as the "perfect organism." Because of this, many humans have attempted to try to control and use them for their own personal gain, usually for military weapons.

The Tarkatan-born Xenomorph retains all of these traits as well as a new feature; segmented blades located in sheathe-like appendages on its forearms. These blades are used to rip, slice and impale targets. As with every Xenomorph, this specimen also has an "inner jaw" in which it can shoot out of its mouth at great speeds, capable of effortlessly punching a hole though tissue and bone.

The Alien then slowly crawls onto its opponent's back, grabbing their head, then headbites it with its inner jaw, going through the skull.

Fatalities

 * Killer Queen: The screen fades to black for a moment, and then the opponent is suddenly impaled through the chest by a Xenomorph Queen's tail. The Queen moves in closer and puts her hands on the opponent's shoulders while simultaneously stabbing her tail even further through the chest. Then finally, after snarling, the Queen completely tears the opponent in half, leaving both the upper body and lower body to fall on the ground. (MKX)
 * Deadly Hybrid: The Alien extends its blades, and stabs the opponent while lifting them up, in a similar fashion to Baraka's Blade Lift Fatality. The Alien then uses its inner jaw to impale the opponent's head, before dropping their body onto the ground. (MKX)

Brutalities

The Facehugger then dies and a Chestburster bursts out of the opponent's chest. After a few seconds, it jumps out and crawls away. (MKX - Konjurer variation)
 * Brutality #5 - The Slicer: Using its Tarkatan blades, The Alien spins his arms around like a helicopter, while in front of the opponent, cutting off their arms. After that, it uses its tail to stab its opponent in the gut, killing them, then throws their dead body away. (MKX - Tarkatan variation)

Ending

 * Mortal Kombat X: "The Alien tore through Shinnok's flesh, reducing him to a bloody pulp. The creature then returned to its nest in Outworld. It continued to venture forth looking for suitable hosts for use in establishing a new hive. The Alien found more than a few intriguing species and dragged them back to its lair. Once a queen had been spawned, the Alien's new hive multiplied quickly and spread unchecked throughout the realm. Emperor Kotal Kahn attempted to save Outworld in a desperate final attack on the Aliens' main nesting ground. The attack failed. Outworld belonged to the Aliens."

Trivia

 * The manner in which the Xenomorph Queen stabs through the opponent and tears them in half in Killer Queen is directly referencing the method in which a Xenomorph Queen dispatched the android Bishop in Aliens.
 * Many of the Alien's combo names are references to the first two movies of the franchise:
 * Kombos Here Kitty, Kitty, Lucky Star, Narcissus, Zeta II, Special Orders, Kane's Son, Warning Beacon, S.O.S and Break Quarantine are all references to the first movie Alien whilst the combo Bug Hunt is a reference to the second, Aliens.
 * A Shokan Xenomorph can be seen during its ending, with Goro seen hanging behind the Alien. There is also a pair of Aliens that appear to have been birthed from Ferra and Torr.
 * When the Predator performs his Skinned Alive Brutality on Alien, it will be decapitated instead due to its exoskeleton.
 * When Cassie Cage performs her Pop Goes Brutality on Alien, its inner jaws will pop out of its mouth.
 * When the Alien wins a match without a Fatality or Brutality, it walks up to the screen, which then goes to black. The opponent is shown trapped and bound in an Alien nest, grunting in pain before a newly-born Xenomorph bursts through their chest, killing them. This makes the Alien one of three characters in Mortal Kombat X who will always kill the opponent after a match, the others being Corrupted Shinnok and the Predator.
 * Depending on the opponent, the Chestburster that appears post-match or in the Alien Baby Brutality may take on a different appearance from it standard form depending on the opponent.
 * When used on the Predator, the chestburster is a Predalien from the Alien vs. Predator crossover franchise.
 * When used on Tremor, the chestburster is not covered in blood and has rock-like skin.
 * When used on its Mirror Match and Mileena, the chestburster has a Takartan's large fangs and little cheek spikes, and spikes on its sides.
 * If the Alien Baby brutality is used on Jason Voorhees, holding down on the D-Pad causes the chestburster that comes out to have a hockey mask. However, this does not happen in the Alien's outro.
 * If the Alien Baby brutality is used on Triborg or Raiden, holding down on the D-Pad causes the resulting Chestburster to be wreathed in electricity. As with Jason, this does not occur in the Alien's outro.
 * Most of the MKX roster will have a special chestburster coming out of them, like Johnny Cage's with sunglasses, Kung Lao's with his hat, and Sub-Zero with his ice mask. This only occurs in the Alien Baby brutality.
 * While the Alien is more or less asexual, the announcer will still tell its opponent to "Finish Him" when it's defeated.
