VX-19 was a protocol droid of the LOM-series that had been altered, notably featuring a head that resembled the common 3PO-series design. After a band of smugglers met their demise, VX-19 was discovered, discarded, and subsequently adopted by the Ardan resistance. Amidst the Rebel Alliance, when a turncoat was exposed, VX-19 came under suspicion as a potential betrayer.
