Humanity had been fighting hard for an entire year shooting, bombs, bullets, missiles, and even a few nukes,but nothing was able to break it and thus humanity was defeated and wiped out of the cosmic map like a grain of sand on the beach.
Princess Celestia had done it,she had transformed most humans into ponies via the potion and the others where killed by the barrier she had made.
Beutifully she had terminated humanity but not there buildings,she had left them intact to take any knowlage she could use to better her ponies lives,and her top researcher Dark Ice had informed her he had found a large under ground lab of some kind dedicated to researching something the humans called a Xenomorph.
Celestia trotted over to the black unicorn who looked at her with a smile. "Hello your majesty ,I found this lab and like you had asked me, and I found this containment cell with what I think is a dragon egg inside it."
"That is something I would love to see,is what a dragon from earth looks like,show me to the cell." Celestia said thinking of what it would look like and what exactly the humans had contained it for.
The unicorn bowed and trotted down the hall and into a small room with a clear glass window that showed the inside of the cell wich contained a brownish looking egg about the size of a normal dragon egg. "This is most interesting,is it due to hatch any time soon?." She asked turning to Dark Ice.
He looked at the Princess. "I am unsure as I have not sent anypony in to check on the egg yet,would you wish for me to do so now your highness?"
Celestia gave a nod. "Yes."
Dark Ice nodded and with a wave of his hoof a guard pony trotted into the cell after he opend the door,the door closing behind him he walked up to the egg.
As soon as the guard stallion got within ten feet it the egg began to shift slightly from side to side, and low gurgling noises came from inside of it.
The princess and Dark Ice stood waiting to see what exactly would happen ,had the dragon in the egg scensed the guard and thinking it was its mother thought it was time to hatch?
With a slow, sucking noise the top of the egg split. It didn't crack. The top of the egg opened like a flower with four thick, wet petals that peeled back to reveal its contents. Layers of mucous and thin, pale membranes concealed most of what was inside from the ponies' view, but the gurd could make out a glistening black colored carapace and a long, flexible tail like an animal's spine gently coiling and slithering around itself.
The guard stallion ave a gulp and backed up some,now unsure if he sould poke at the egg now that he was sure that watever that was it was NOT a dragon egg.
The newly-hatched creature suddenly moved with unbelievable speed. Tail whipping around like a snake, the thing launched itself out of its egg and directly at the guard stallion, unfurling long, spidery legs that had webbing like a ducks foot. Before he could even process what was happening it was on his face and gripping his head with those hideous thin legs while the tail tightened around his throat.
The guard stallion only had time to let out a gasp before he was on the floor trying to peel it off,only to go limp moments later.
Princess Celestia and Dark Ice gave a look of horror at what whas happining to the guard stallion and Dark ordered two more guards to go in and pry that think off there friend,when they tried to do so it's tail tightend more around the stallions throat.
They backed off for fear of hurting the guard and waited for whatever was to come.
Celestia turned to Dark,wondering if he knew exactly since he sent him to resaerch anything he could find here. "Dark,so you have any clue what that thing is?"
He shook his head. "No your majesty."
She looked to the guard with the creature on his face. "Then we have no choice but to wait and see what happens since that thing wont come off without killing that poor stallion." Dark Ice nodded in agreement.
Had they known what that was they would have gladly killed that stallion and turned the entire place to ashes.
What had attacked and attatched itself to that stallion was a facehugger,and not just any facehugger it was a QUEEN facehugger.
Now you may be wondering 'whats the diffrence?' to put it simply this facehugger impregnates a host with two alien embrios in the chest,a drone and a queen,and once its done it will continue to live for about an hour after it falls of the hosts face.
It was about two hours later that the creature had fallen off the stallions face and crawled away ,and gave the guards a chance to get that poor pony to the medical wing of the facility and placed him into a bed to rest,they left to let him get some sleep so that one he woke up they could do some tests to see if he was ok.
But he would never wake up as he coughed in his sleep and with an explosion of blood and bone two little Xenomorphs shot from his chest with a screach and slid into the vent.
They slithered around in the vents and into an unmarked room with ten more eggs in it,it had been sealed off to all but the vents before the place was abandoned to escape the barrier.
The newborn Xenomorphs had no limbs, like a snake, and the pronounced dorsal ridge indicated the presence of a backbone, but instead of scales its hide was segmented like an exoskeleton, and they had no visible facial features except for a mouth full of sharp teeth and second inner jaws,the Queen however had larger head and the sides curved out.
The eggs sensing the presance of a queen opened up like the first ,and the facehuggers crawled into the vents to impregnate new hosts and make more drones for the young queen.
The drone and the queen had molted there skins and grew to adult size about a day later ,when some guards had gone to check up on there friend the facehuggers had gotton them to and made five warriors and five drones,all of wich draged the bodies back to the queen so she could feed and grow.
Celestia stared in horror at the bloodstains that used to be her guards before turning to Dark Ice. "We are leaving and sealing this place off,now" She said,and with out any warning teliported away with Dark and left the remaining four guards alone with the hostile aliens.
The four remaining guards where picked off one by one,and each one had been brought to the queen for consumption or to be used as a host.
These Xenomorphs where diffrent from the classic Xenomorph XX121,as said alien in question took on some qualities of its host ,so these aliens had hooves and stood like a pony,some hard jagged horns or webbed wings,but they all had one thing in common and it was there will to protect there queen and continue the species.
Two weeks later in new canterlot Celestia was enjoying some tea when a guard ran into the throne room sweating and panting as talked. "Princess,I come with urgent news of the facility you requested us to guard and seal off."
Celestia looked up at him. "Yes,what is it?"
He gave her a horrified look. "Every guard stationed there has been killed."
Celestias tea cup dropped from her magic grip and shattered on the floor splashing its hot contents onto the floor. "How?" she asked with a neutral look.
He sat down. "I do not know your highness I had just gone there to check up on my friend steal wing but all I found where bloodstains and corpses."
Celestia sent the guard on payed leave.
It was then that a loud screaching filled the air and she heard her guards fighting outside,taking a look out a nearby window she saw something out of a horror movie,her guards being slaughtered by large black equine like insects.
She would have called them changelings but they where clearly far from a changeling because of there large banana shaped head,second inner jaws,and long deadly bladed tails that where currently being used to stap any guard that tried to fight back against them,any who sucsedded learned quickly of the xenos acid blood and how painful it was to get it on ones face or legs since the poor bastard who did melted away and died quickly.
In the center of it all was one larger then the rest and it was two times bigger and taller then Celestia,it gave a screach and the xenomorphs quickly killed the rest of the guard and the queens head turned to Celestias direction and before she could react she was grabed from behind by one of the aliens,and she screamed as its tail shot through her chest,she coughed up blood but still alive.
The alien seeing its prey still alive opened its mouth to reveal a second mouth,and it shot out and right through the solar alicorns skull killing her instantly.
The queen was pleased she had managed to find quite a lot of hosts for her facehuggers and the aliens soon defeated all of equinity and surprisingly enough left the new foals alone ,not bothering to use them for hosts since they could sense something was wrong with them and it would not go well if they tried to.
