Swamp gas was a chemical weapon designed by Jenna Zan Arbor and used by the Confederacy of Independent Systems against the Gungans of Ohma-D'un. Although it could kill Gungans in seconds, it took somewhat longer to kill members of other species. It caused blistered skin and internal bleeding.
Obi-Wan Kenobi recovered the antidote on a mission to Queyta with Jedi Masters Fay, Nico Diath, Knol Ven'nari and Jon Antilles. The Jedi fought Asajj Ventress and Durge for the antidote, though Obi-Wan alone survived to return to the Jedi Temple.
As of 20 BBY, the Galactic Republic had enlisted the help of the Luurian Genetic Enclave to study the swamp gas antidote, and believed the threat of Separatist bioweapons was over—although the research on Queyta would lead to the creation of Trihexalophine1138, the chemical weapon that devastated Honoghr.
Swamp gas may have had links with dioxis, the toxic gas commonly used by Neimoidians to dispose of their enemies. On Cato Neimoidia, Obi-Wan Kenobi identified a toxic gas emitted from Nute Gunray's mechno-chair as dioxis, though it was later verified as swamp gas by Captain Dyne of Republic Intelligence.
Behind the scenesEdit
Swamp gas may be based on mustard gas, as it resembles it closely in its effects.
