To what E09 said, i would really like to take Praetorians as genderless, even though they are not canon material and also off-topic, praetorians are my second-favourite aliens. Therefore, i would like them to stay what they are: Hive guardians. Their name comes from the personal guards of the Roman Emperors, called "praetorian, praetoriani". And i also dislike the queen molting idea, even thoguh it's pretty cool when you play AvP2 online with that option. The only option i like to accept is that Praetorians are guards, and the queen requires an egg molting a superfacehugger, a queen chestburster and THEN there is a queen. This is the most "canon" idea i can think of. Praetorians are not in the movies, therefore not accepted as a valid option here on this site, but if they were to ever be put in the movies, i would have liked them to come from darker facehuggers, like the ones in AvP-R. And to only be 2 at the same time at most in a hive. I have a small idea for a plot for introducing a praetorian in a movie right now hmmmm...
