Mouse Droid (MSE-6-Series Repair Droid)
It is fair to say that this character is not one of the more widely discussed of the Star Wars characters, infact the humble Mouse Droids rarely get a mention.
They scuttle round the Death Star and Star Destroyers, moving not unlike a mouse, though they do not have tails. Generally used for repairs and maintenance work, they can move fairly fast and can often be seen in the background.
Character cool factor: 3
Most likely to: be whizzing around in the background
Least likely to: get caught in a mousetrap
