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 1d4+5 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 20 ft. and those caught in the area of effect are allowed a Ref save (DC 13) to avoid taking damage. If the save fails, the victim will suffer 1d4+5 points of damage per round, for 1d6 rounds.

Xenomorph Hate (Ex) Even though this creature is the result of combining human and Xeno DNA, it has a distinct hatred of any Xenomorph it encounters. When it sees another Xeno, it will go into a killing frenzy after only 1d4 rounds. During this, the Newborn gains a +4 to hit and the damage inflicted against Xenomorphs is automatically doubled.

Hybrid Affinity (Ex) The creature has a natural affinity towards hybrids, and will never attack or actively attempt to harm any hybrid it encounters. It will listen to simple commands issued by the hybrid, and will fight to defend the hybrid if it encounters any sort of hostiles.

Natural Weapons (Ex) Cannot be disarmed.

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.


The experiments which created the Hybrids also had a very unexpected side effect. One of the queens produced during the experiments was created with a human-like womb and gestated a new type of Xenomorph. This creature was born in blood and violence and killed the queen in the process.

The newly dubbed ‘Newborn’ turned out to be very hostile to anything it encountered, until it discovered the first hybrid, at which point it took the hybrid to be its biological parent. The creature did not attempt to harm the ‘parent’ and even showed simple emotions like betrayal when the hybrid ended up causing its death. Since these events, more of these ‘newborns’ have appeared across known space, especially when hybrids are involved.

Physically, Newborns are taller than your average human, typically standing nearly 8 feet in height. They are pale creatures, with soft flesh, missing the typical hard exoskeleton possessed by the other variations of the Xenomorph species. Also unlike other members of the species, these creatures possess actual eyes, and are perfectly adapted to seeing in the dark. The skull is elongated, like the rest of the species, and they have powerful claws and a deadly bite, but are lacking the inner jaw.  They are also stronger than the average Xenomorph and can typically defeat Drones and others with relative ease.

The blood of the beast is acidic, but diluted, and as such does not cause quite as much damage when it is spilled.

They are highly aggressive, and will attack anything – with the exception of hybrids, on sight. They also possess a powerful hatred for the Xenomorph type, and will always attack to kill whenever they encounter the creatures.
