So many of these droids were owned by high-ranking Imperials on the original Death Star that they were nicknamed "Death Star Droids". Appearing to be a standard RA series servant droid, the Death Star Droid is one of the Imperial Security Bureau's many tools. Death Star Droids like 5d6-RA7 (pictured above) had a small addition to their primary programming--loyalty to the Empire, and not their stated master--was inserted into their programming. They were then given to high-ranking officers throughout the Empire. Death Star Droids would observe their designated "master" and report any suspicious--or outright treasonous--activities immediately to the ISB.
