Mug'garat was a male Advozse underworld figure in the service of Rogun Matt'rik throughout the Galactic War fought between the Galactic Republic and the reborn Sith Empire.
In the year 3642 BBY, Rogun dispatched Mug'garat to handle the smuggler who would eventually be known as Voidhound, who at the time thought he was assisting the Voidwolf. Following the destruction of the King's Ransom treasury ship while it was in orbit around Nar Shaddaa, Mug'garat trapped Senator Bevera Dodonna in a desperate attempt to bait Ace into an ambush. In the expectation that Rogun would be pleased by his success against Ace, he and a pair of his Ssorokks fought the smuggler, but they were all ultimately defeated and killed.
