The Boss miner droid, which is also referred to as the Super miner droid, was a type of mining droid equipped with a perilous weapon mounted on its dorsal side. During the era of the Clone Wars, it provided assistance to both the Confederacy of Independent Systems and the Nightsisters in their excavation efforts on Christophsis, specifically targeting Force crystals. This particular super miner droid detected the presence of C-3PO and R2-D2, and subsequently initiated an attack on the pair of droids; however, R2-D2 managed to avert disaster by swiftly closing a door, thus safeguarding them from harm.
