Special Abilities

Acid blood (Ex) The blood of the Xenomorph is highly acidic. Whenever it bleeds, the blood will burn through almost any substance and will cause 1d6+24 points of damage. The blood will continue to burn for 1d6+6 rounds, causing damage each round. Attacking the Xenomorph with natural weapons is a very poor idea. With the spitter it is far worse – when the creature dies, it will burst, washing an area equal to 20 ft. in acid. A Ref save (DC 28) will save anyone caught in the area of effect from the splash. The acid causes 1d6 damage per round for 1d6 rounds.

Acid Splash (Ex) Whenever the Xenomorph is hit by any type of attack which deals more than 10 points of damage in a single strike; the blood will have a chance to effect anyone near. The acid splash has a radius of 10 ft. and those caught in the area of effect are allowed a Ref save (DC 28) to avoid taking damage. If the save fails, the victim will suffer 1d6+24 points of damage per round, for 1d6 rounds.

Cling (Ex) The Xenomorph is able to move its full speed along any surface.

Grab (Ex) The creature must make a claw attack, it will do normal damage. If the attack roll successfully hits the target’s KAC +4, the creature automatically grapples the foe as a free action. (If it hits the targets KAC +13, it instead pins the target). Instead of dragging the victim back to the hive, the creature will instead attempt to kill the target on the spot.

Inner Jaw (Ex) Possessing an additional ‘jaw’ the creature can opt to use this attack. It typically will use this on a grappled target, or it can opt to use this in addition to the bite. The bite does slightly less damage (1d6+5 S) but is more accurate. The creature has a +42 with this particular attack, and if the target is grappled, then the bonus is +45.

Natural Weapons (Ex) Cannot be disarmed.

Stalker (Ex) The Xenomorph is a near-perfect predator. As such it gains a +5 racial bonus to stealth rolls, and whenever the creature is in a hive, this bonus increases to +10

Swallow Whole (Ex) If a creature with this special attack begins its turn with an opponent grappled in its mouth (see Grab), it can attempt a new combat maneuver check (as though attempting to pin the opponent). If it succeeds, it swallows its prey, and the opponent takes bite damage. Unless otherwise noted, the opponent can be up to one size category Smaller than the swallowing creature. Being swallowed causes a creature to take damage each round. The swallowed creature will take 2d6+6 points of acid damage per round. A swallowed creature keeps the grappled condition, while the creature that did the swallowing does not. A swallowed creature can try to cut its way free with any light slashing or piercing weapon the amount of cutting damage required to get free is 65 points.  Or it can just try to escape the grapple using Acrobatics (Escape DC 53). If a swallowed creature cuts its way out, the swallowing creature cannot use swallow whole again until the damage is healed. If the swallowed creature escapes the grapple, success puts it back in the attacker’s mouth, where it may be bitten or swallowed again.

Trample (Ex) As a Full-Round Action, a Creature with the trample ability can attempt to charge any Creature(s) that is at least one size category smaller than itself.  The creature is able to target anything in a perfectly straight line, no matter how many targets are in that line.  All Targets of a trample takes 19d8+44 damage. Targets of a trample can make an attack of opportunity, but at a –4 Penalty. If targets forgo an attack of opportunity, they can attempt to avoid the trampling Creature and receive a Reflex save (DC 28) to take half Damage. A trampling Creature can only deal trampling Damage to each target once per round, per target in the direct line of attack; no matter how many times its movement takes it over a target Creature.

Vulnerability to fire (Ex) The creature has few vulnerabilities, and fire is one. Whenever it encounters fire, the creature will take an additional 50% damage (rounded to nearest) and suffer a -4 to any saving throws involving fire.

Thanks to the ability to clone and replicate DNA, scientists were able to bring back many long-extinct species. While many found this practice to be unethical at best, and downright deadly at worst, many ancient species, having been extinct for millions upon millions of years were resurrected.

One of the first creatures to have been brought back was the infamous Tyrannosaurus Rex, once thought to have been the apex predator of the world.  The beast was cloned and put into theme parks (with often fully expected horrific results) and even placed on plants and allowed to grow and breed freely.

Somehow it was discovered that the Xenomorph had found its way to a planet which was home to these particular creatures. And somehow, one managed to become implanted. It is speculated that the cloned Tyrannosaurus managed to eat or swallow several Facehuggers, which managed to survive and were able to implant the embryo into the body of the beast.

The result is the most terrifying and deadly of all the Xenomorphs ever encountered. The creature is so powerful as to be able to destroy Kings, Queens and all other variants without suffering too much damage as a result. The creature is an absolute killing machine, and lives only to hunt, kill and consume. It has no desire to capture, as the beast has no hive (although it will occasionally use a hive it has cleaned out as a den), and has no need to reproduce. In fact, the beast is known for attacking hives just out of spite in order to feast upon the queen (for some reason it seems to have a taste for the egg-sack and considers the eggs themselves to be a real treat).

The best way to deal with the creature is to take off and nuke the entire site from orbit. It’s the only way to be sure.
