MSE-6-G735Y, or G7 for short, was a MSE-6 series repair droid who was the fastest mouse droid in the Imperial fleet, so much so that TK-421, the stormtrooper in charge of maintaning him, wanting to be transferred to Coruscant with the droid so he can submit it for racing. It bumped into Chewbacca when he, Han Solo and Luke Skywalker were captured by the Death Star's tractor beam. It was serving as a messenger between TK-421 and the Imperial officer who he fell in love with.
