A Praetorian is the next stage after a Warrior , but before a Praetorian is a mature Queen Guard. It becomes a Pre-Mature Praetorian. A Pre-Mature Praetorian runs on all fours and is smaller than a Mature Praetorian. It is stronger than a Warrior and has a better chance of surving more bullets. A big enemy to it is a Predator which will try as hard as they can to kill the Praetorian to make sure it does not become a Queen Alien .
