The RA-7 protocol droid 4D6-J-A7 served the Galactic Empire's Imperial Security Bureau as an administrative assistant during the Age of the Empire. As a result of intrusion protection applied on her databanks, 4D6-J-A7 developed a conceited attitude that led to her looking down on other droids of lower station. She was present in the Empire's Citadel Tower on the planet Scarif when a battle against the Rebel Alliance began, which culminated in the tower's destruction by the Empire's Death Star superweapon.
