Indiginous only to the Xenomorph home world; Palatines, Chosen Protector or Chosen Few are the elite of the elite in terms of xenomorph castes. The Queen Mother's Queen-sized personal guard, they are tall and gangly, much resembling anorexic Praetorians with long horn-like tines and long pointed cranium. They are the most violent strain of the xenomorph species. Serving only the queen mother they reside in large orb-shaped coccoons outside the royal chamber where they quickly dispatch any outside intruders with their primitive savagery. In the event a queen mother dies they will molt into a new one with the aid of royal jelly in the queen's chamber becoming the subordinent leader of all the aliens on the planet.
