BB-R3, better known as Nimbus, is the quirky astromech droid of X-Wing pilot, Jessica Sterling. Nimbus has an interesting sense of humor, one that has led many to believe the droid had been flawed straight off the assembly line. He will often drive his owner crazy by hiding her things or playing little pranks on her but it is all in good fun. Nimbus is a loyal companion and is never far from Jessica's side. The pair are practically inseparable and despite the frustration Jessica could not ask for a better astromech.
