Praetorian

The Praetorian is perhaps one of the most interesting strains within the Xenomorph biology. Its primary role within the Hive is to guard key locations of importance or interest, and if nothing else, to protect the Queen herself.

Anatomy and Genetics
There are many theories as to where the Praetorian originates from, whether it is "pure born", meaning it is born to take form as such and protect the hive, or that frankly it evolves from the basic caste drone in a molting process or both.

However most seem to believe that the Praetorian is formed as a last stage in a drone's life cycle. This theory states that there is a period that each drone who lives long enough goes through, which involves molting and growing to immense heights; while the process goes on however, it emits a strong pheromone that enrages the Hive, thereby making most inhabitants aggressive towards the outcast Drone, causing it to retreat to the outward world. Eventually it is said to return as a Praetorian, if it survived.

The physical features of the Praetorian is very pristine: its appearance looks very similar to the Queen; it has a crown-like head crest, large height, and powerful strength.

In most refreces it is the last stage of a xenomorphs life cycle before it turns into a queen.

Behavior
The behavior of the Praetorian is possibly one of the most graphic and intense of all the strains, excluding the Queen. Not only is it 'programmed' to automatically become hostile to any foreign intruder of the Hive, but also with the molting process, in which it emits pheromones that somehow enrage other strains.

The Praetorian could be seen as smarter then most xenomorphic castes, as it is quite possibly the next in line for the role of the queen.

Facts

 * Praetorian is a special force of skilled and celebrated warriors used by Roman Emperors, perhaps defined as "Guard" in term.
 * Praetorians are featured in the following games: Aliens Vs. Predator, AvP2, Aliens vs. Predator: Extinction, AVP Arcade, and various console titles.
 * In various games, the Praetorian is depicted in different ways, in Aliens Vs. Predator the strain walks on all fours, and pounces most of the time. In AvP2, the strain is massive, and has no ability to wall walk. And in AvP:Extinction they can release spores to track enemies.
 * It could be said that the term "strain" does not suit the Praetorian, seeing how it is a base form of the Drone.
