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+2 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.

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 11) to avoid taking damage. If the save fails, the victim will suffer 1d6 points of damage per round, for 1d6 rounds.

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

Grab (Ex) When the Xenomorph happens to be within range of a hive, it will often attempt to grab and drag a victim back to the hive to be cocooned and impregnated. 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). If it succeeds, the creature will then drag the victim back to the hive to be used as a host. The victim can attempt to break free while grappled, requiring a successful escape (using the acrobatics skill). If the victim turns out to be ‘troublesome’ the creature can opt to bite in order to make the target more ‘compliant’.

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 +11 with this particular attack, and if the target is grappled, then the bonus is +14.

Natural Weapons (Ex) Cannot be disarmed.

Pack Tactics (Ex) When two or more of the creatures are together, they will hunt in packs the way canines such as wolves hunt. They will use tactics in an attempt to corner prey, and they will always attack at the same time to ensure they can get flanking.  For every two creatures in the pack hunting a single target, they will gain a +1 to hit.

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

Trip (Ex) The creature can attempt to trip its opponent as a Free Action without provoking an attack of opportunity if it hits with the specified attack. If the attempt fails, the Creature is not tripped in return.

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.


It is well known that the Xenomorphs use a portion of the host’s DNA to complete their life cycle. Every creature that is ‘born’ has some traits from the host, although they do retain the overall humanoid appearance.

This particular type of Xenomorph still retains the usual appearance of the species, but the torso is wider in the chest and narrower at the hips. The rear legs are also jointed in the same manner as a canine’s. As such, the monster does tend to move on all fours, and can often be seen lowering its head to ‘sniff’ at the ground, in the same manner as a dog or other similar life-form.

The creature tends to be more bestial than the others of its species, and when there are multiple members of this particular ‘subtype’, they do hunt in packs.
