CZ-4 was a CZ-series secretary/business communications droid that belonged to the Hutt crime lord Jabba Desilijic Tiure. In 4 ABY, the broken body of the secretary droid was piled in a corner of the droid "assessment" room in the dungeon of the Hutt's palace on the planet Tatooine when the supervisor EV-9D9 met the new droids C-3PO and R2-D2 there. CZ-4 was missing its legs and had its right hand attached to its left arm.
