virus is well virus he was made from the flu strand along with subhuman and other dna.

he cant survive without eating human flesh ( at least once a month)and he is not a cannibal. he has very few traits that make him non human

his traits:

he can grow back body limbs

hes is basicly immortal since virus's dont have a life span

he feels minimal pain

and if his blood is some how absorbed in your body you will mutate not into a zombie but to the apperition of your guilt sin and hate.

he has no need for oxogen

other than that his runing speed strength and other atributes are that of a human
