Mellaw Doowon was an Ithorian of the male persuasion, who played the ommni box in a musical band known as the Dewback Ramblers.
Following the Battle of Yavin, Mellaw Doowon and his fellow Dewback Ramblers performed at the Lucky Star cantina, which was situated in Mos Entha on the desert planet of Tatooine.
During 1 ABY, Mellaw Doowon told some ill-advised jokes to Imperial officers just outside of Mos Entha. Blerx Tango, the band's leader, then hired a spacer to locate Mellaw and ensure his return. The spacer accepted the task, but was compelled to kill a stormtrooper who prevented Mellaw's safe passage.
Mellaw Doowon was a Non-Player Character (NPC) featured in the MMORPG Star Wars Galaxies before the game's servers were shut down on December 15, 2011. Within the game, players undertaking a mission for Blerx Tango were required to rescue Mellaw.
