3B6-RA-7

3B6-RA-7 was a RA-7 protocol droid that originally served the Imperial Security Bureau. 3B6 was programmed as a protocol droid and a spy droid, sent to watch the actions of Grand  Moff Dunhausen. Dunhausen heard of the rumors about how the RA-7 were being used as spies, and Dunhausen disposed of the droid. Later, 3B6 was captured by a Jawa clan on Tatooine and became an almost permanent feature of the Jawa Nebit's Sandcrawler, not  being able to be sold. 3B6 would mock the other droids that the Jawas brought aboard and had a grumpy personality. Eventually, 3B6 was sold to the farmer Sholh Dorr, who 3B6 grew a connection with, only to be sold later. At this point, the RA-7 series was a collecter's item because most of their kind had been destroyed along with the first Death Star.
