Alien's P.O.V:
It stood there in the middle of the area, listening to the sound of battle far away in the entrance to its "Hive". That was what this structure was called, The Hive. It was one of them, one of those the Humans refer to as Xenomorphs. But unlike the others, it wasn't made naturally, that is to say that it doesn't follow its brethren's lifecycle. Instead, it was made in a lab, a test subject and nothing more, by those Humans. It could remember every single word spoken by those "scientists", which they called themselves, spoken to it.
"You are new age of Xenomorph," it remembered those "scientist's" words "a creature stronger than any other. Your capabilities were enhanced to maximum height. You have been given everything, from enhanced bulletproof exoskeleton, to twice your normal speed, twice your normal strength, and most important of all, a gift of great intelligence. You have been made to outdo your brethren even the one who gave birth to you. You are our Harbinger of Death." Intelligence, is that how it's remembering every word they've spoken, and understanding every word they said. Indeed, it was like none of its brethren. It was said to even be stronger than "one who gave it birth", the Queen.
It stood there listening; the sounds of battle on the entrance could now be heard even louder. It knew who its attacker was. They called themselves "Yautja" and the humans called them "Predators". It had seen how powerful they were, but had never fought one before. They were known to have been able to take out dozens of its kind; it had seen them done that. They killed its brethren like cockroaches, now in its mind, is the time to show those creatures what it's like to be killed like cockroaches.
On one of the entrances, where a light was shining on that area, it could make out one of those Predators, and two of its kind fighting. Something appeared on the Predator's mask, like a red line, aiming straight for one of its brethren's head. A shot was heard, and a blue bolt of plasma hit the Xenomorph's head, killing it instantly. The other one charged at the Predator, but that attempt was also in vain, for another blue plasma bolt was fired, killing that one instantly as well. The Xenomorph's anger rose seeing how that thing killed its brethren. "Now" it thought "is your time to die", or something similar to that.
The Predator immediately took notice of it, and the red laser line was aimed right at its head. A bolt of plasma was shot, coming straight at it. It strafed and leaped to its right, dodging the bolt of plasma, almost a little too easy. It hissed at the Predator standing in its sight, in a mocking way. It now began its charge, running at the Predator at blinding speed. The Predator fired another bolt of plasma, only to have it dodged again. It now could see its target, the Predator, nearing it, and with one pounce, it pinned the Predator onto one of the walls. The Predator extended a blade from the right wrist, and took one stab at its head. It tilted its head, and dodged the Predator's attack, again, almost too easily. The Predator was now at its mercy. Opening its mouth, its second pair of jaws aimed straight at the Predator's forehead, its drool from the jaws dripping down to the floor. With one shot from its second jaw, it pierced the skull of the Predator, killing the Predator instantly.
It began to hiss with triumph, for it was its first Predator kill. Immediately, it sensed something else near it. It could hear it, and see it, for it need no eyes to see. It saw a pair of blades, nearing its body on its side, preparing to stab it. It could now see the wielder of the pair of blades, another Predator, seeking revenge for its fallen comrade. It could see the Predator's body, and with great aim, jabbed its tail right to its side and piercing the Predator's chest before the Predator even had a chance make an attack. This had become its second Predator kill. "How many more shall fall today" it thought.
