The Liquidator was a bulk cruiser of the Neutron Star-class that belonged to the Imperial Navy, and it was under the command of Admiral Winstel Greelanx.
During the Battle of Nar Shaddaa, the vessel met its end when Mako Spince, piloting the Dragon Pearl, destroyed it, resulting in the wrecked remains of the ship falling onto Nal Hutta, the planet that hosts Nar Shaddaa and the original home of the Hutts.
Subsequently, portions of the ship's armor plating were recovered, and Han Solo acquired them to strengthen the hull of his ship, the Millennium Falcon.
