TC-16
this silver-plated protocol droid served Nute Gunray at his residence on Cato Neimoidia, during the last decades of the Old Republic. After Anakin Skywalker and Obi-Wan Kenobi forced Gunray to flee the purse-world, they found a number of his possessions had been left behind in his haste to escape. In addition to the Viceroy's mechno-chair, the Jedi also discovered TC-16. The droid was removed from Cato Neimoidia and debriefed on Coruscant, before being turned over to the two Jedi as a liaison during their search for Gunray. It was TC-16 who helped them gain access to Workshop Xcan on Charros IV, where TC-16 was briefly taken aside to be realigned and polished while the Jedi talked to t'laalak-s'lalak-t'th'ak. In the wake of the experiences on Charros IV, TC-16 was sent to Coruscant for debriefing, before it was assigned to Aurek Team during the search for Darth Sidious. When the team was destroyed just after entering Sidious' lair, TC-16 was confiscated and was never seen again.
