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 9d4+9 points of damage. The blood will continue to burn for 1d6 rounds, causing damage each round. Attacking the Xenomorph with natural weapons is a very poor idea as the target automatically suffers the acid blood damage if they are using slashing or piercing attacks.

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 16) to avoid taking damage. If the save fails, the victim will suffer 9d4+9 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 (1d10+13 S) but is more accurate. The creature has a +24 with this particular attack, and if the target is grappled, then the bonus is +27.

Natural Weapons (Ex) Cannot be disarmed.

Rapid Implantation (Ex) If the creature successfully grabs a target, it can attempt to strike with the inner jaw attack. The difference is if it so choses, the creature can shove the inner jaw down the throat of the victim, causing only half damage. As long as the creature maintains the grab, it can then begin to implant embryos, at the rate of 1 per round, up to a maximum of six embryos after six rounds. Each round the beast will inflict half the damage from the inner jaw attack, and it can sense if the victim is going to succumb to the injuries, at which point it will release the victim, having fulfilled its biological imperative. Implant (Ex) Once a victim has been successfully implanted, the embryo will continue to grow. It will take as little as an hour or as long as several days before the embryo has grown enough to survive outside the host. At this time the embryo will then tear through the chest of the victim, killing it in the process. Typically the victim will have 4d12 hours before the creature bursts through its chest. If the victim is given medical treatment (actual surgery), the victim has a chance to survive. A surgeon (life science, medicine) will need a successful roll (DC 16) to remove the embryo. If the roll fails, the victim dies in the process.

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

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.

his Xenomorph was thought to have been unique, after a Facehugger impregnated the member of a race of high-tech predatory hunters, who used a pre-space flight civilization as a hunting ground.  This has since been discovered to be false.

The creature is slightly tougher than a Praetorian guard, and has the aspects of queen, but is nowhere near as tough. Still due to its way of procreating the species, it can be far more dangerous, if given a chance to gain a foothold.

Physically, the Predalien has the same physical structure as the rest of the species, although the back-spikes are not quite as pronounced. The skull is only slightly larger than that of a regular human’s, and possess strange, dreadlock-like spikes. The beast still possesses an inner jaw like the rest of the species, but there is also a set of mandibles to either side, legacy from the genetics of the hunter species it originated from. Lastly, the beast’s exoskeleton is a far paler shade in coloration, gradually darkening the closer it comes to the back.

Unlike a queen however, and what makes this particular specimen so deadly, is the fact all it has to do in order to impregnate a target is latch onto the face and shove the inner jaw down its throat. After it does this, the creature will impregnate the victim with multiple embryos, instead of just one.

The beast is as strong as a drone, and can easily render metal and inflict heavy wounds with its claws and tail. It is also more intelligent than the simple drone or the other variations, and is arguably as intelligent as the Queen.

It can create the same material as found in most Xenomorph hives, but unlike the queen, it does not lay eggs, and relies on the drones it creates through implantation to capture other hosts to bring back to the hive in order to be given the ‘kiss of life’.
