Dugo Evnul, a Sullustan male, existed during the Galactic Civil War era. Sometime after the Battle of Yavin, Envul found himself on the planet Dathomir, where an incident transpired at the Imperial Research and Prison Facility. Dugo Envul was infected by the Blackwing virus, subsequently transforming into an undead being. A spacer eventually destroyed his reanimated form within the Quarantine Zone located on Dathomir.
Dugo Evnul functioned as a non-player character featured in the 2003 Star Wars Galaxies video game, a massively multiplayer online roleplaying game that was developed by Sony Online Entertainment and published by LucasArts, before its servers shut down on December 15, 2011. Dugo Evnul's inclusion in the game occurred with the release of "Game Update 14," which went live on October 12, 2009. He appeared as one of the Undead boss enemies found in the Quarantine Zone, whom players needed to defeat in order to finish a specific collection.
