"A structurally perfect organism, no doubt." - Dr.Groves
Xenomorphs are generally an stealthy, ambush-attack-based, incredibly dangerous species of extraterrestrial creatures. They possess a bullet-proof hide, acidic blood, the ability to see the electromagnetic signature of their prey, a tail capable of effortless tearing limbs off, and adhesive feet that allow them to travel on all surfaces.
- A single xeno leads a charge and destroys a giant barricaded metal door.
- Rips through steel.
A drone throws a yaujta through stone.
Rip apart fully armored soldiers.
Breaks apart a rifle with one swing of their claws.
Cuts a man in half with one swing of their claws.
A weakened xenomorph throws a fully grown woman dozens of feet into the air.
Dodges a point blank shotgun blast.
Dodge a shoulder cannon blast.
Shrugs off bullets.
Tanks plasma blasts.
Shrugs off impalement.
They deal with yaujta punches and kicks regularly.
Effortlessly survives impalement.
“It takes heavy armour-piercing military-grade weaponry to kill one and even then its not easy. We have the reports from Colonial Marines’ encounters with them. A Chinese farmer with a pitchfork, an Australian bird hunter with a shotgun, they’ll be wasting their time trying to stop a full-grown alien with either of those weapons.”-Aliens: Earth Hive pg. 248-249
“The sounds of combat were drawing much closer as they finished. He could here the occasional ricochet ping off the alien armour, and whoever had taken over from the dead general would probably be hauling ass real soon.”-Aliens: Earth Hive pg 274
“A bullet sprang off the thing’s head, doing no more damage to the hard surface then a rubber ball bouncing on a plastercrete sidewalk. The alien turned and looked at the unseen shooters. “Aim for the woman!” somebody screamed. “Shoot Janna!” Before the alien kidnapper could flee with its prey, three more shots boomed. One of them missed completely. One of them hit the aliens chest, flattened on the natural armour, and did no harm. The third bullet hit the woman, just above the left eye.”-Aliens:Nightmare Asylum pg 4-5
Just a few more examples of bullet tanking.
Alien acid -
A few xeno deaths result in enough acid to destroy a cave, melt APCs and tear through acid resistant suits. It's also worth noting that a xeno rips off a guy's head in this scan.
Just an example of how hard it is to kill xenos without dying.
Even a small splash of it will kill.
Another visual example of how powerful this acid is. This acid has consistently eaten through spaceships, built to withstand battle cruisers, in seconds.
Xenos will profit off of one another's death.
Stealthy enough to get the jump on Predators.
Describe as equal hunters with the yaujta.
Two different instances of fighting predators, now, while predators normally win, they always put up a helluva fight.
Xenos can climb on any surface and then impale and throw/carry away their prey.
Xenos can jump great heights, over existing hordes and tackling down their enemy.
Sense chemical changes.
A xeno will gladly sacrifce itself for a kill, its long tail being incredibly deadly and being able to impale enemies even when they are in a secure position.
