Tiomvo was a male Human residing on Tatooine during the era of the Galactic Civil War. Following the Battle of Yavin, he became affiliated with a group of criminals operating within the impoverished sections of Mos Espa. This group also consisted of Hilbrun, Eyleen, and Guz'Ordnak. In the year 1 ABY, they sold a motivator booster controller from an R2 unit to Watto, a junk dealer. One of the members of the group used his swoop bike as a guarantee, but the debt to Watto for the booster controller was never settled. Due to the fact that both Imperial Commander Barrezz and Rebel Captain Bastra sought after this R2 unit, a spacer later attempted to reclaim the motivator booster controller. Tiomvo and his fellow thieves immediately engaged the spacer in combat, but the spacer was successful in recovering the booster controller from Hilbrun's USV-5 Modified Landspeeder.
Tiomvo appeared as a non-player character within the video game Star Wars Galaxies: An Empire Divided from 2003, a massively multiplayer online roleplaying game that was developed by Sony Online Entertainment and published by LucasArts. The game's servers were shut down on December 15, 2011. Tiomvo was incorporated into the game as part of the "Legacy Quest" content update, which was released alongside "Publish 25," also known as the "New Game Enhancements," on November 15, 2005.
Based on the game's directory .tree files and related reference materials, the character was originally going to be named Kleetuz.
