- "Good day, my master wishes me to inform you that we are not dealing today. He is out of stock and must make an aquisition trek."
C4-ZX was a 3PO-series protocol droid active during the Galactic Civil War sometime after 0 BBY. The droid was owned by the Jawa trader Ji'Ni Sil. The droid stood with its master at the Jawa Mountain Fortress on the planet of Tatooine. Circa 1 ABY, Ji'Ni Sil was approached by a spacer who was looking for a body casing from a R2 unit that once belonged to Peggin Dulin. The droid was actually wanted by both Imperial Commander Barrezz and Rebel Captain Bastra. C4-ZX informed the spacer that the droid casing was already sold to a robonium miner. Despite the miner was killed by Tusken Raiders, the spacer finally managed to retrieve the casing.
