A microscopic alien virus discovered by scientists after a sample of frozen water was collected on another planet and it was found inside still alive but in a suspended animation like state. It is parasitic in nature as well as a virus therefore it will feed off of its infected hosts blood and the nutrients in the hosts body until there is nothing left but it is a very slow processes. However it also performs a symbiotic like relationship with the host first curing the host of any disease or infection as well as increasing the animal proteins in the host body increasing their strength and speed as well as senses all the while infecting the nervous system to destroy it so it can take control over its host body and brain. It does this because it wants the host to feel healthy and strong that way the host will not think anything is wrong with themselves before it is to late! That way if it is found and taken out it has a biological fail safe programed into its body to cause the host brain, heart and lungs to shutdown completely.
