Bao-Dur (voiced by Roger G. Smith) and the Remote are characters in Star Wars: Knights of the Old Republic II: The Sith Lords.
Bao-Dur is a Zabrak from Iridonia, and a technician who fought under the command of the Jedi Exile during the Mandalorian Wars. Bao-Dur is the inventor of the Mass Shadow Generator that ended the battle on Malachor V by completely obliterating the Mandalorian Armada and inadvertently killing many Republic soldiers on his own side of the battle, leading to a great deal of guilt later in his life. The Exile (who much later befriended Bao-Dur) gave the command, which sent massive echoes in the Force throughout the galaxy. Bao-Dur is trainable as a Jedi Guardian.
