Chapter 1
(Somewhere in a icy climate inside a research station)
"It's remarkable its physiology is like nothing I've ever seen what we're the results of the tests on its blood?"
"It burned through the PH paper faster than I could see the results."
"Do you think it could burn through the walls of its cage?"
"Probably not I mean it was only paper and how would it cut itself to spill the acid anyway?"
"True- what was that?"
"It sounded like gunfire!"
*The hum of electricity dies away*
"The power!"
"But the cage holds the... urm what did we name it?"
"A Xeno" (Its capitalized since it's the genus name if they called it a runner or drone it wouldn't be.)
"Right! but isn't electricity what keeps the Xeno's door shut?"
"Shit..."
Meanwhile in the Xeno's cage visible from the lab in which the two scientists were speaking
(The cage is a stainless steel cube with one entryway and a electrified barbed wire box in which usually the "Xeno" would be stored.)
The alien in question had a ridged head and had been there about 2 months after going from chest burster to a drone then maturing into a warrior. The alien (for easily being able to identify it we'll call it Prediatirus) Prediatirus immediately climbed up the walls of his cage onto the ceiling and out the door he saw the life forms through the door on his right so he crawled onto the roof
"Bob do you feel something watching you?"
"Yea I do..."
Prediatirus swung his blade edged tail at them beheading both of them then dropped to the ground and smashed the tubes holding the smaller spider like people that he felt were his kind (Face huggers) and immediately after he left the room the secondary power came on causing the alarm to start to blare Prediatirus hissed as the light irritated his eyes then smashing any light he came across until he reached the living quarters section he saw that many people were still in their rooms and that the small crablike creatures were crawling into their he had a strange feeling he should leave them do whatever they planned on doing and he ventured deeper into the facility meeting little resistance from the bipedal life forms he came across until he felt a calling from a large gate and above that gate were the words do not enter (He can't read them obviously) Prediatirus looked for a way in finding none... He sees a pedestal with a glowing light square on it. With his newfound hate for light Prediatirus smashed it "magically" causing the gate to open albeit slowly then he saw... her.
