This BB Unit "Resistance Edition" Astromech Droid has greatly improved astrogation programming, allowing it to perform incredibly more complex maneuvers and store additional hyperspace coordinates or jumps within its memory.

This BB Unit "Resistance Edition" Astromech Droid has been upgraded with an advanced electrical defense grid that allows 13 to operate at a reduced capacity when hit with ionized electricity, and prevents any permanent damage or loss of functionality.

13 has developed a personality revolving around analytics with no room for imagination. This results in a myriad of statistics and rules of logic being delivered routinely. Such a personality can be grating on others, and often is greeted with annoyance.

13 has been fitted with a digital lockpick that replaces a standard finger with a set of small deployable tools that allow it to pick physical locks and slice digital locks.

13 has been altered to appear more dark theme with some colors instead of being completely black. Black paint has been applied to the droid's exterior, allowing for accented sharp silver and dark green plating.
