B3NK was a the navigator/tactical droid onboard Ki-Adi-Mundi's personal starship. He was also known to be very protective of the ship's computer, as well as his fellow crewdroids, especially J1M. He was programmed for computer and system integration, navigation and tactical speculation. After the successful mission on Tatooine, the Loronar Corporation bought B3NK's schematics to create the B3NK series. B3NK helped Ki-Adi-Mundi track his daughter, Sylvn and the wanted criminal Ephant Mon.
