Dubbin Sharr was a chief and fanatical Muskeg Gungan male who was active near Theed on the planet of Naboo during the Galactic Civil War. In 1 ABY, Sharr's attempt to enlist the wanted murderer Hunnos Jarkey to assassinate members of the Naboo human government was unsuccessful. Later, Lieutenant Khartoor from the Violent Crimes Division instructed RSF operatives to investigate Sharr's group of Muskeg extremists. Sharr met his end during this raid.
In the 2003 video game Star Wars Galaxies, Dubbin Sharr made an appearance as a non-player character. This massively multiplayer online roleplaying game was developed by Sony Online Entertainment and published by LucasArts. The game was shut down on December 15, 2011. Sharr was integrated into the game as a part of the "Legacy Quest" with the release of "Publish 25," also known as the "New Game Enhancements," on November 15, 2005.
