An 8D-series smelter droid served the Pyke Syndicate on Oba Diah, operating as a torture droid within the prison of the High fortress of the Pyke Syndicate. The smelter droid was assigned to interrogate the sisters Rafa and Trace Martez after they failed to deliver a shipment of spice from Kessel. However, when Trace Martez was brought to the droid, she managed to escape and shoot down the Pykes holding her, one of whom fell onto the torture droid.
