TZ-9999 (Veteran series)

TZ-9999, nicknamed later "Teezee", was a T-series tactical droid who served the Confederacy of Independent Systems  as commander of Lott Dod's flagship: the Federation's Savior; during the Second Battle of Cato Neimoidia, which resulted in the destruction of the vessel and the defeat of the Separatist task force.

Reactivated and reprogrammed to enforce the laws and policies of the Galactic Empire, TZ-9999 would see service in the Imperial navy under Moff Lazarus Bast and briefly under Supreme Commander of Imperial Military Darth Vader aboard the Federation's Savior - newly christened Veteran, the command ship of the Veteran fleet. TZ-9999 was destroyed with the rest of the droid crew and Moff Bast in the Liberation of Sullust.
