MK-09 was considered a very aggressive, but also very friendly, droid, with a sense for adventure and excitement. He shared the same sense of distaste against the rival Viraxo shipping company that the Azzameen family did. After the involvement of the Galactic Empire in the Azzameen's affairs, MK-09 developed a distaste for the Imperial organization as well. Emkay suggested to Ace, his sister Aeron Azzameen, and brother Emon Azzameen that they join the Rebel Alliance, citing Luke Skywalker's success at the Battle of Yavin.
