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
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
