Background
R06-R was a common OOM/B1-series security battle droid, before receiving several modifications by their current 'employer', including the vaguest hint of a personality and minor knowledge of medicine and the art of war.
They currently operate as part of a Separatist-aligned group within the Republic, serving for a senator of the Separatist party.
Motivation
Repayment.
Separatist Senator Thak Namrix is the one who arranged R06-R's modifications, and gave them their (modicum of) free will. Naturally, the droid is thankful for such a gift, and wishes to repay it with loyal deeds.
Duties
Support [10]
One of R06-R's core precepts is to aid their fellow mercenaries, political allies and/or hired hands. It is an irresistible compulsion for the droid; if it tries to resist, it may very well begin to malfunction, overheat and generally suffer from numerous negative effects.
Description
A common OOM/B1-series security battle droid, R06-R appears like most clankers, though they possess the characteristic red coloration on their 'shoulders' and 'collarbone' as is standard with security-type B1s.
Uncharacteristically, their armor coating is covered by a heavy cloak, designed to conceal and protect their chassis.
The rifle they tote about is a standard-issue E-5 rifle used by most B1 droids, modified with a scope (making it an E-5s, standard for Security-type droids). The weapon itself is of average quality, which would seem subpar to an organic.
