JJR-579 was a stormtrooper stationed aboard the Sovereign, the flagship of Grand Moff Wilhuff Tarkin, approximately five years before the Battle of Yavin. Stationed at the TIE Fighter Depot aboard the vessel, he was present as the Jedi Knight Kanan Jarrus was being transported for his final interrogation. During these events, a TIE fighter that had been commandeered by the Spectres entered the hangar and JJR-579 commented to his companion, JTN-303, that the vessel's colorful paint job was against Imperial regulations. JTN-303 replied that he kind of liked the design, and JJR-579, a dedicated soldier of the Empire, was about to question his companion's loyalty when the TIE fighter set off a stunner, knocking the two stormtroopers out.
