An 8D-series smelter droid functioned as a torture droid for the Pyke Syndicate on Oba Diah, specifically within the prison located in the High fortress of the Pyke Syndicate. This smelter droid was tasked with the interrogation of the sisters Rafa and Trace Martez because they had not successfully delivered a spice shipment originating from Kessel. Nevertheless, when she, Trace Martez, was presented to the droid, she successfully broke free and eliminated the Pykes who were guarding her, with one of them falling and disabling the torture droid.
