DD-19
From Wookieepedia, the Star Wars wiki.
DD-19 was the DD-19 "Overseer" labor pool droid assigned to the New Republic corvette FarStar. It was nicknamed "the slavemaster" due to its harsh treatmeat of other droids. DD-19 was primarily assigned to the droid repair bay on the ship, and had the authority to apply restraining bolts to unruly droids.
