Facehugger

it is a parasite

latches onto a human host's to breed a baby alien embryo in their chest cavity

it only has one goal

to implant a alien embryo in its host's chest

implants an alien baby inside your chest

once it latches onto the face of a host it will force a 4 foot long ovipositor down their throats into their chest cavity where it will lay several eggs

it's eggs barely fit down the host's throat

when it lays eggs inside the host's chest the eggs are almost too big to fit down the throat making it bulge painfully

the ovipositor will cause the host to become sexually aroused

when the ovipositor goes down the host's throat it secretes a slimy substance inside the host causing him or her to be turned on in a state of extreme arousal

facehugger's appearance

it has 8 finger-like digits to grasp the host's head and a long tail that wraps tightly around the host's neck to prevent the host from removing the Facehugger

can move really fast and leap great distances

it's strong tail can work like a spring to propel the Facehugger to leap onto a host's face. it's finger like digits can work like legs to scuttle around quickly

doesn't talk at all

the Facehugger doesn't speak it only carries out actions to impregnate it's human host

oral impregnation

it will slide it's ovipositor into the host's mouth, into the throat, past the gag reflex deep down into the host's chest cavity

the host won't suffocate

the ovipositor down the throat provides oxygen for the host to breathe since the impregnation process takes a few hours to complete

movie character

from the alien films with Xenomorphs

paralysis

the Facehugger secretes a chemical onto the host's face causing the host to fall unconscious and paralyzed for the impregnation process so the host is unable to struggle

release from finishing

once the facehugger latches onto you or the host's face,it will not remove itself to finish the impregnation process until you order it to. So basically you control when and how long the impregnation process is

convulsions

when the facehugger is impregnating someone, the host's body will convulse violently as they gag on its ovipositor
