B-9D7 was the personal assistant of Movo Brattakin.
When Olag Greck crashed into Brattakin's private hangar, Brattakin was fatally wounded. B-9D7 saved him by removing his brain and placing it in the droid's cranium. In the droid body, Brattakin deceived his associates, while carrying out his plan to start a droid rebellion and topple Boonda the Hutt. The plot was foiled by C-3PO and R2-D2, and Brattakin's droid body was decapitated by a shot from Jace Forno's blaster.
