AR-G0 was a pilot droid owned by the smuggler Beryl Thorne operating out of Taris during the Cold War. Unlike most pilot droids, which were fifth-degree droids, AR-G0 was a third-degree droid. Thorne named AR-G0 the second in command of her operation on Taris after suffering the losses of many contacts to rakghouls. AR-G0 was separated from Thorne escaping Nar Shaddaa when infighting between the Hutt Cartel broke out.
