Age of Rebellion
AR-47 is a custom-made RA-7 protocol droid, previously in the service of Grand Moff Tarkin… at least so it claims. A translator droid fitted with an Imperial persona, AR-47 deeply dislikes organic beings and favors the machine-like order of the Empire. It has recently – highly unwillingly – joined forces with the Rebel Alliance, essentially only because it dislikes the warlords of the former Empire even more.
AR-47 is not designed for combat, but is fluent in a multitude of languages and can easily absorb new ones.
