N3R2 "Number 2" has had every external component painted black as night, with attempts to minimize the brightness of external lights and features. This allows this DRK-1 Probe Droid to more easily blend into the shadows and darkness unseen.

N3R2 "Number 2" has developed a predatory nature similar to those often associated with assassin droids. As a result, N3R2 "Number 2" will often approach a situation with the mind set of a hunter, and convey their findings as such. This can be disconcerting to others who are unaccustomed to N3R2 "Number 2".

Rins'zler has modified his DRK-1 droid to function as a spotter while he is engaging in sniping aspects. The Droid is fitted with enhanced optical lenses as well as sensor systems and ballistic processors that allow it to pick targets and accurately calculate the required range etc and transmit this to Rins'zler, the Droids sensors have a 360 degree operating sphere and can be used to keep watch while The operator is looking down the scope. The addition of these upgrades has reduced the amount of armour the droid can carry, in addition to this the droid no longer carries its typical self repair equipment. The Droid has a slightly lower speed when using its replusor systems, this would be a downside to some, but within the role it carries out it provides only a slight disadvantage.
