This unnamed vessel appears in two episodes of Series VI: "Gunmen of the Apocalypse" and "Rimmerworld". It is crewed by Rogue Simulants who roam deep space, looking for other vessels to hunt or compete with in battle for the purposes of sport, and occasionally to capture humans to torture for their sadistic pleasure. It contains a number of components looted from other vessels, including an escape pod taken from a seeding ship. It also incorporated a great deal of advanced technology (most notably a teleporter) and a large store of food in order to sustain the Simulants' torture victims.The Simulant ship is heavily armed with laser cannons, and the Simulants will occasionally equip unarmed vessels with their own weaponry to make the hunt more sporting. The Simulant ship is apparently not very well armoured, however, as a few laser blasts from Starbug were enough to blow the Simulant ship into two halves. Apparently the Simulants were accustomed to their prey fleeing, and were not accustomed to their prey standing ground and fighting back.
The Dwarfers later return to the site of the battle and board one half of the wrecked Simulant ship as they are in need of food supplies.
The ship's first design was in the shape of a human skull. This was changed to a goat skull and finally, to make it fit in with the overall Western theme of "Gunmen of the Apocalypse", to a cow skull.
