** Furthermore, if the villains ''were'' successful in killing everyone on I-Island, the villains would find out the hard way that the Slayer [[AcquiredPoisonImmunity was still alive]], and [[RoaringRampageOfRevenge eager to hunt them all down]], [[CruelAndUnusualDeath to tear them to shreds]] ''[[CruelAndUnusualDeath alive and screaming in helpless terror.]]''

* ''VideoGame/UnboundSaga'' have areas clouded in [[SicklyGreenGlow green]] "Radiation vapor", which you must escape within a given time limit before the vapor drains you of your health. Said areas tend to contain either BeastMan or mutant mooks, immune to the radiation.

* In an old UsefulNotes/AppleII text adventure game with graphical aid, ''VideoGame/MaskOfTheSun'', at one point you are locked in a room filled with gas (which the game presents by showing an entirely green screen). To get out without dying (and you have a limited time), you have to figure out the exit is on the southwest, a direction atypical to text adventures at the time.

** ''VideoGame/SuperMario64'' has the Hazy Maze Cave, which has the aptly named Hazy Maze complete with poison yellow gas. Unless Mario is wearing the Metal Cap, prolonged stays in the Hazy Maze prove to be fatal. In the UsefulNotes/{{DS}} remake, the gas is purple, and it's Metal Wario that can survive in it. If any character gets a hidden Mega Mushroom, they can stand in it since their heads are physically above the gas... until the mushroom wears off. Also, any character in the gas actually ''coughs visibly'' if you don't move them while losing health.

* In the *Piggy* AU story *[[https://www.wattpad.com/story/310982122-dilly-the-great-war Dilly: The Great War]]a fictional gas named "Orange Cross" is used on the battlefield, but instead of the gas killing it's victims. Anyone who breathes it becomes infected zombies, the gas was also used in artillery shells and bombs.

* ''WesternAnimation/TheVentureBros'': In Season 6, Rusty, Billy, and White create "God-Gas" which is intended to inflict mind control on anyone who inhales it. The gas ends up causing the affected to experience realistic hallucinations that drives them mad.

* One of the many types of gases used by the vile borg, Noxious in ''WesternAnimation/SkysurferStrikeForce''.

* In ''WesternAnimation/TeenageMutantNinjaTurtles2012'', the yellow gas on the Kraang's planet that they recreate in the TCRI building is toxic to Earth beings.
** Conversely, to a Triceraton, Earth's oxygenated atmosphere acts as such, though it's slow-acting. The victim suffers from hallucinations, but given enough time, breathing it would likely cause permanent brain and lung damage and eventual death.

* ''Film/KongSkullIsland'': One of the soldiers is carrying canisters of an unnamed toxic gas when the first Skullcrawler attacks. During the fight, the soldier is killed and the cannisters catch fire, causing them to explode. The resulting gas cloud forces the characters to scramble to escape it, but no one is actually killed by it.

* In ''Manga/SailorMoon'', or more precisely, Codename Sailor V, Sailor V (Minako) has the power to use this. She uses this against [[A group of Mosquitoes]] in the Pets arc, using a low concentration, but could have brought the full force of the Venusian atmosphere, which means a pressure 92 times that of the atmosphere of Earth, at 460 degrees Celsius (800+ Fahrenheit), and almost entirely carbon dioxide which suffocates you, plus some sulphuric acid that would melt you down. Yikes.
