Queen Facehugger

The Queen Facehugger has the ability to lay Queen Embryo inside a host. It can also lay more than one embryo before dying. Lt. Ellen Ripley was impregnated by one of these.

The potential Queen Facehugger also impregnated a dog, leading to the Runner Xenomorph. It should be noted that when the Runner discovered Ripley, it did not attack, sensing the Queen inside of her. It is not known if a Xenomorph will refuse to attack an individual infected with an ordinary xenomorph, or just a Queen.
