The Onyx Cinder starship possessed a system known as the emergency hull demolition sequencer. In approximately 9 ABY, the droid SM-33 was instructing the younglings Fern, KB, Neel, and Wim on piloting the vessel when Wim attempted to press a concealed button. This button would have initiated the sequencer, but SM-33 intervened, cautioning him against ever touching it. Despite this warning, the sequencer was later triggered during their escape from Lanupa, resulting in the jettisoning of the Onyx Cinder's external hull, along with its primary engines, transforming the ship into a more streamlined configuration.
The initial reference to the emergency hull demolition sequencer occurred in the Star Wars: Skeleton Crew television series episode entitled "Way, Way Out Past the Barrier," which was the second episode and debuted on December 2, 2024.
