Dioxis

From Wookieepedia, the Star Wars wiki.

Dioxis gas released onboard the Saak'ak over Naboo.

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

Obi-Wan Kenobi and Qui-Gon Jinn hold their breath as dioxis fills the room.

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 released dioxis gas via variable gas emitters into the Saak'ak's conference 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—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.

[edit] 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.[source?]

From the name, it could be implied that the gas was composed of two oxygen atoms, however O2 is not lethal.

The name "dioxis" is most likely derived from the real-world virulent chemical compound, dioxin.
