Great Hyperspace War Campaign
A replacement medical droid serving the crew of the Black Nova.
Its predecessor M3-D1 was left behind and destroyed on a skirmish against wookiees and the Sith in Kashyyyk.
Although of a very similar model, M3-D2 is known to not have the same quirky and flightly personality of M3-D1. However, it is just as diligent in performing medical duties to its very busy crew.
