The RX-series bell droid refers to a type of RX-series pilot droid employed by Star Liner Travel throughout the New Republic Era. Frequently, these droids served on commercial airliners, transporting passenger baggage onto the starliners and performing security scans on individuals to ensure compliance with the prohibition of weapons on board.
The initial appearance of the RX-series bell droid occurred in "Chapter 5: Return of the Mandalorian," specifically in the fifth episode of The Book of Boba Fett, a live-action television show available on Disney+. Bryce Dallas Howard directed this episode, which was broadcast on January 26, 2022.
