Pretorians:
Class A Bio-Mechanical Android

Although created with nano technology, the Pretorians are classified as Bio-Mechancial, for their amazing likeness to living organizims. Abilities and attributes are as follows:

° Regenerative System
° Adaptive Defences and Weaponry
° Progressive Upgrades
° Built in multi-sensors (normal, infared, night vision, x-ray)
° Built in long range communication
° Built in artillary

Other abilities and weapons change from each pretorian to suit the specific needs of each one. Items such as communication dissruptors, or anti-tank missles may not be on one, but will be on another, to whichever one will bennifit from it the most.

The basic design of the pretorian is unusually unique for any we could have come up with. Everything about them was created and designed by the nanos themselves. Their unusal use of animal prefernces for each different Pretorian is confusing, yet it doesn't make the preformance suffer, so it is hardly what one would call a problem.
Also, the symbols and markings on the metal of the Pretorians are also created and designed by the Nanos, though we think they don't seem to have any meaning.

The basic design of the Pretorian's base frame is thin and slender, unusually light, and remarkably strong.

Also, an unusual trait of the nanos, they seem to create Pretorians specifically for their new mind.. before we even find a new voulenteer.
