Star Wars - Edge of the Empire
Gaol Ming's former personal droid.
MX-SX7 was the personal droid of Gaol Ming but was stolen by Bey, LEG-10N and Elaiza when they fled his mansion. As a quick fix solution Bey was able to reprogram the robot to believe that he was it’s former master however the fact that it’s current circumstances are completely at odds with what it believes to be true is taking it’s weight on the droid and it is starting to develop serious character flaws as it’s programming is unravelling.
The droid is quite valuable as it as quite an old and rare model and is in extremely good condition. If it were taken out of service there are a lot of collectors who would happily pay a small fortune to have it.
