The XX-3P0 was a model of protocol droid that was produced during the waning years of the Galactic Republic.


XX-3P0s were manufactured in the city X2-4, on the moon Uffel. In c. 31 BBY, the rogue droid LN-73 modified a number of XX-3P0s inside their factory on Uffel, replacing their forearms with weapons mounts and programming them to attack any organic beings who entered the room.
