Biography
Master-Com was patched directly into the computer systems of The Wheel, and monitor virutally every aspect of the statiom at any time, including security and life support. When Imperial Commander Strom tried to take control of The Wheel on his own, he was forced to destroy Master-Com in order to reach Greyshade. Greyshade, however, revealed that Master-Com was not a single droid. A new and improved version of the Master-Com droid was activated, helping to thwart Strom's schemes. This new Master-Com unit was quite interested in the self-sufficiency of R2-D2 and C-3PO, and arranged for them to be freed after they were placed in storage for later reprogramming. When Greyshade confronted Master-Com about his interest in the droids, Master-Com explained that he simply wanted to have some friends. This new Master-Com unit also perished in a hail of Imperial blaster-fire, when it attempted to open Greyshade's personal docking bay so that the Administrator could escape from Strom. Luckily, it was able to transfer control of the station to a third body, which emerged from hiding to discovere that R2-D2 had recordings of all the treacherous activities of Greyshade and Strom.
