A class of large droid that resembled the much smaller MSE-6 series repair droid, also known as the "mouse droid," was used by the Galactic Empire in military locations like the Super Star Destroyer Executor and the DS-2 Death Star II Mobile Battle Station.
Behind the scenes
The large mouse droid first appeared in the 1983 film Star Wars: Episode VI Return of the Jedi. The droid was also filmed as part of a cut scene depicting Darth Vader and Luke Skywalker arriving aboard the Second Death Star. Footage from the filming of Return of the Jedi was later applied to the Special Edition of Star Wars: Episode V The Empire Strikes Back.
