kind of a rough idea!!! like a mixture of the thing and the dark side of the moon and the host story
-their "alien parasites" had crashed on a ship and all their other parasite comerades died and disappeared and now xh3nos and ali3ns parasites found their hosts and they're awake and roamin' the earth
-xh3n0 isn't fully morphed with her parasite yet like ali3n is, she keeps trying to fight it so it's taking a long while, gender starts to disappear with almost complete morphing [[like ali3n's]]
-the alien parasites have a hierarchy system much like ants and bees and wolves, xh3n0 is like a "supervisor" or beta, and ali3n [[since they're fully morphed with their parasite]] is an alpha/has almost reached the "divine" state all the parasites want to achieve
it was just something i based them off of, i still don't know if i want to run with it or drop it :///
