In "The Machine in the Ghost," a special Star Wars Rebels short, the rebels' Ghost starship is under attack by a wave of TIE fighters. Hera pilots the craft, while Kanan tries to blast the Imperials from the Ghost's gunner. While they do evade and shoot down several TIEs, it's up to astromech droid Chopper to finish the job – even if he's reluctant to do so.
