Dioxis/Legends

"Dioxis!"

- Qui-Gon Jinn over Naboo

Dioxis was a potent toxin often used by the Neimoidians of the Trade Federation at the time of and following the Battle of Naboo. The green-white gas was highly toxic to most carbon-based lifeforms.

When Jedi Master Qui-Gon Jinn and his Padawan Obi-Wan Kenobi were sent by Supreme Chancellor Valorum to negotiate the blockade of Naboo, the ambassadors were double-crossed by Nute Gunray. The Neimoidians let off dioxis gas in the conferance room where the Jedi waited. However, their command of the Force afforded them a sense of the danger, and were able to survive in the toxic environment until a squad of security battle droids arrived with orders to dispose of their bodies.

Thirteen years later, on Cato Neimoidia, Obi-Wan Kenobi identified a toxic gas released by Nute Gunray's mechno-chair as dioxis&mdash;though this toxin was also identified as swamp gas, the chemical weapon used by the Separatists on Ohma-D'un earlier in the Clone Wars.

Behind the Scenes
Qui-Gon Jinn's line upon sensing the dioxis was simply, "Gas!" in The Phantom Menace. However, George Lucas altered this to make the gas sound more exotic and other-worldly.
