IG-86 Sentinel Droid has had its programs re-written and mechanical systems hard-wired for combat operations. This augmentation gives this IG-86 Sentinel Droid a significant increase in combat efficiency in eliminating targets on behalf of Elad Cirith, but at the expense of it being usable for much else except for combat.

IG-86 Sentinel Droid is subjected to frequent memory wipes, and has little to nothing in the way of personality. It acts according to its basic programming in an efficient and impersonal manner.

IG-86 Sentinel Droid has had additional memory installed that increases its computing power. This allows it to perform complex analytical operations at a marginally faster rate, but limits the ability to further customize the IG-86 Sentinel Droid in any other way.

IG-86 Sentinel Droid has had every external component painted black as night, with attempts to minimize the brightness of external lights and features. This allows this IG-86 Sentinel Droid to more easily blend into the shadows and darkness unseen.
