TT-3P0 was a blue-plated 3PO-series protocol droid that served the outlaw tech gang TechTank at their concealed base on the moon Nar Shaddaa during the Galactic Civil War. After becoming embroiled in a gang war with the Hutt Noako, the Hutt crime lord Sinasu took shelter among TechTank. A group of Sinasu's agents traveled to the TechTank base with a cargo of Krayt dragons for the crime lord and on their arrival, TT-3P0 was sent out to greet the agents.
