KLR-B3 was one of four prototype KLR series combat droids produced by the Army Weapons Research Department on the rogue planetoid Tembora in the Tembora Research Station. It was shut down after only the initial system trials due to malfunctions found in KLR-B1's software programming which caused him to turn into a psychopath. KLR-B3 was taken by the base from the surviving members of the Maid of Sentiile. It is unknown what happened to the droid after this.
