History Sandbox / BatmanCanBreatheInSpace

Done through Literature.

* Done by the Aquabats in ''Series/TheAquabatsSuperShow''.

* ''Series/BattlestarGalactica2003'' featured a season 3 episode where the Chief and Cally are forced to do an unprotected spacewalk (really just a jump into a waiting Raptor) when an airlock malfunctions and seals them in. Treated pretty realistically, Cally is in pretty bad shape afterwards but the Chief is mostly OK, but then [[spoiler:he IS a cylon and thus can be expected to be a bit tougher to environmental hazards.]]

** It is established that due to their alien biology, Time Lords such as the Doctor can survive in the vacuum of space without the need for external protection.

** Not in space, mind you, but close: in [[Recap/DoctorWhoS13E1TerrorOfTheZygons "Terror of the Zygons"]], the Fourth Doctor and Sarah Jane are trapped in a hyperbaric chamber being drained of oxygen. He puts Sarah into a trance, telling her she does not need to breathe, then puts himself into one until they are rescued.
** In [[Recap/DoctorWhoS17E4NightmareOfEden "Nightmare of Eden"]], the Fourth Doctor puts himself in a hypnotic trance to survive a shuttle trip without benefit of oxygen.
** Taken to heavy levels in [[Recap/DoctorWho2011CSTheDoctorTheWidowAndTheWardrobe "The Doctor, the Widow and the Wardrobe"]], where the Eleventh Doctor can not only breathe, but can ''talk'' in space without the need of a spacesuit or space helmet (He still needs a spacesuit, as he falls to Earth afterwards). Possibly the ship's artificial atmosphere was still functioning, though it's not mentioned.
** [[Recap/DoctorWhoS33E7TheRingsOfAkhaten "The Rings of Akhaten"]] is the most insane example in the new series. ''Everyone'' is going around in a planetary ring system that appears to be open to the vacuum of space. The only explanation is that there's probably some kind of atmospheric shell — but this is not brought up in the episode.
** [[Recap/DoctorWhoS37E5TheTsurangaConundrum "The Tsuranga Conundrum"]]: The Pting doesn't breathe oxygen, and is unaffected by the vacuum of space.
* For the most part, ''Series/{{Farscape}}'' manages to avoid this trope, the exception being D'Argo. Apparently Luxans can survive unprotected in space for "a [[{{Microts}} quarter-arn]]", and in the miniseries he uses this ability to [[KissOfLife keep someone else alive]] longer than they normally could have. Also, in the mini-arc "Look At The Princess", John Crichton manages to hold his breath long enough to float from one craft to another. Even though the air pressure will rupture your lungs, that's why you ''don't'' hold your breath in a vacuum, though that's the least of that scene's problems with science . . .
* Becomes a plot point in ''Series/KamenRiderFourze'' TheMovie where [[spoiler:Gentaro finally realizes that his dream girl Nadeshiko isn't human]].

* ''Series/{{Lexx}}'' gives its human characters spacesuits consisting of... a helmet with a plastic visor covering the eyes. That's all. [[Administrivia/TropesAreTools But it it's all part of the charm]].
** Kai justifiably doesn't wear one because he is [[TheUndead undead]] and has no need for breathing or life support. He strolls around outer space in his normal outfit.
* ''Series/LoisAndClark'' sees Superman hanging around in space without any protective gear. Then, just as everyone's convinced that he can do that because [[NewPowersAsThePlotDemands he's Superman]], he takes Lois for a trip up there with him. Without any sort of breathing apparatus. And has a conversation with her there.
* ''Series/MysteryScienceTheater3000'': Mike and Pearl occasionally sit in the open door of Pearl's space-worthy VW Bus. But if you're wondering how they eat and breathe, and other science facts, just repeat to yourself [[MST3KMantra "It's just a show, I should really just relax"]].

* ''Series/PlanetAjay'': This show takes place on the eponymous India-like planet, and every character is able to breathe on the planet with no problems whatsoever. The only character who wears a spacesuit in the show is Bud the astronaut, and even then nothing happens in the series that confirms if he can actually breath Planet Ajay's air without a spacesuit.
* ''Franchise/PowerRangers'' plays this one mostly straight. ''Series/PowerRangersLostGalaxy''[='=]s Mike was able to survive, albeit unconsciously, in the vacuum of space, while ''Series/PowerRangersInSpace''[='=]s Carlos could take an unmorphed little girl for a ride on his Galaxy Glider. Most JustForFun/{{egregious}}ly, the team-up episode "Forever Red" features the villains ''riding horses on the moon.''

* In ''Series/RedDwarf'': "Confidence and Paranoia," Confidence tries to invoke this trope while outside of the ship with Lister. [[spoiler:Lister refuses to go along. Confidence then tries to encourage him by taking off his own space helmet [[ExplosiveDecompression and explodes]].]]
* The Comicbook/MartianManhunter on ''Series/{{Smallville}}'' not only can survive in space, being in Earth's atmosphere actually inhibits his HealingFactor. Well, he ''is'' from Mars; air's a lot less thick and oxygenated over there.
* ''Series/StarTrekVoyager''. In "Film/TheAdventuresOfCaptainProton" holoprogram Tom Paris is seen [[JetPack jetpacking]] through the vacuum of space protected only by a [[AdventurerOutfit leather jacket and aviator goggles]]. Since it's an AffectionateParody of [[Film/FlashGordonSerial 1930s sci-fi]] {{film serial}}s, even the slightest semblance of realism isn't on the cards.
* In the ''Franchise/UltraSeries'', it seems that pretty much every non-human character is capable of breathing in space. Ultras regularly fly back and forth through space between Earth and M78, kaiju fly through space or are carried out of Earth's atmosphere without any trouble, and even the aliens who do get about using spacecraft are still able to fight the Ultras in space.

* Major Tom in [[https://www.youtube.com/watch?v=D67kmFzSh_o this]] video for Space Oddity.
* Music/{{Rammstein}} in their video for "[[{{Eagleland}} Amerika]]", where they appear on the Moon in astronaut suits but without helmets. [[spoiler:Since the Moon surface where they perform is revealed InUniverse to be just a set.]]

* If the backglass and AstralFinale of ''Pinball/JunkYard'' are taken into consideration, the player character flies into space with nothing but a fish bowl for oxygen.
* The MatchSequence for ''Pinball/ThePartyZone'' shows Captain B. Zarr flying through outer space in his rocket, with the cockpit open and exposing him to vacuum with no ill effects.

* The RuleOfFun/[[RuleOfCool Cool]] physics of the ''TabletopGame/DungeonsAndDragons'' setting ''TabletopGame/{{Spelljammer}}'' allow this: there is no oxygen in space, but whenever an object goes into space, it takes an "envelope" of air with it. So everyone can breathe in space, for a minute or handful on their own. The amount of air is proportional to the size of the object, which helps the crew of a huge ship, but not a giant, for example, since it uses proportionally as much air. After a while, the air becomes stale and eventually runs out, though far-traveling ships usually avoid it with air-creating spells or plants. Escape velocity or burning up in the atmosphere aren't problems -- if you go up high enough, you end up in space, simple as that. All of this was designed to allow SpacePirates to [[RuleOfCool stand on the decks of their wooden ships]]... [[RecycledInSpace In Space]]. Incidentally, the way gravity works is even weirder.\\\

* ''TabletopGame/Warhammer40000'':

* ''TabletopGame/OldWorldOfDarkness'':

* ''TabletopGame/VampireTheRequiem'' notes that vampires technically can breathe in space. [[FridgeLogic Then again, isn't the inability and lack of need to breathe, regardless of environment, one of the key qualities in defining a vampire?]]
* Another RuleOfCool[=/=]RuleOfFunny example is ''TabletopGame/TalesFromTheFloatingVagabond''. The owner of the titular bar installed an atmosphere generator. The setting notes that races discover they can breathe in space as soon as the light from the bar's sign reaches them.
* This can be simulated in games that feature superpowers. ''TabletopGame/{{GURPS}}'' can simulate it nicely with enough points. It's even (relatively) cheaper in ''TabletopGame/MutantsAndMasterminds'', being somewhat in-genre.
* In ''TabletopGame/EclipsePhase'' any morph with the "Vacuum Sealing" augmentation can survive in space, so long as they have air.
* ''TabletopGame/{{Starfinder}}'': Star Shamans start the game with the ability to breathe in space and immunity to other unpleasant effects of vacuum exposure.

* ''Ride/SpaceMountain'' at the Ride/DisneyThemeParks sends guests off into outer space in completely-exposed rockets, and yet they are able to breathe just fine.
* At Ride/UniversalStudios:

Done through Film - Live Action.

Instances where a character has advanced technology or superpowers, but it's not clear if they justify the character surviving in space, are marked as '''Unsure - powers'''.

* Reginald Martin (under the pen-name E.C.Elliot) wrote a [[http://www.collectingbooksandmagazines.com/kemlo.html series of fourteen juvenile SF books]] featuring protagonist [[http://en.wikipedia.org/wiki/Kemlo Kemlo]] and his friends, the "spaceborn". Merely by being born on an orbital space station, they gained the power to "breathe" in space, and needed to wear protective suits to enter an atmosphere.
* In Donald Moffitt's ''Second Genesis'', the "cuddlies" have evolved to survive in space for extended periods. They have adaptations such as extra lungs, nictitating membranes across the eyes, sealable nostrils, and the ability to supersaturate their cells with oxygen like whales. [[RequiredSecondaryPowers Presumably they also have toughened skin and bodies to prevent the pressure in their own bodies from rupturing its way out]].
* In ''Literature/FromTheEarthToTheMoon'' by Creator/JulesVerne, soon-to-be-shot-into-space adventurer Michael Ardan is asked whether it is not foolish, since there is little if no air on the Moon? "Then I will only breathe on special occasions!" he quips.

* The ''Literature/{{Discworld}}'' novel ''Literature/TheLastHero'' deals with a {{Magitek}} spacecraft despatched from the Disc which, while this was wholy unintended, ended up landing on the Discworld's Moon. It is noticeable that the Moon has an atmosphere which while thinner, is breathable. This is handWaved on the grounds that the gravitational field of the Moon is sufficient to hold its own air; Creator/TerryPratchett explicitly states that while never totally absent, the air gets a ''lot'' thinner away from the major planetary bodies. (The first Discworld book, ''Literature/TheColourOfMagic'', has the protaganist actually falling off the Discworld and realising sufficent air to breathe will be a problem, at least for a few minutes or so, while things resolve themselves.)

* In ''Literature/LifeTheUniverseAndEverything'', the gang is able to stand on a bare asteroid after Slartibartfast [[BystanderSyndrome extended an SEP field over them, thus making the problem of lack of air "Somebody Else's."]] Which is pretty irresponsible when you think about it... Or rather not, as the concept of the SEP field is better summarized "not MY problem".

* Sergei Pavlov's ''Literature/MoonRainbow'' series feature some humans who entered into a symbiotic relationship with a (non-sentient) race of living {{Nanomachines}}, which apparently could do an instant and reversible matter-energy conversion on the whim, and thus acquired a whole bunch of cool super powers. One of these powers was that they didn't actually need to breathe anymore, as the symbiotes would supply required oxygen directly into the cells through the energy-matter conversion.\\

* Barrington Baley's The garments of Caean some of heroes (like Alexei Verednyev and his girlfriend Lana Armasova) just live in space. They know they can. [[spoiler:They are colonists who wear their advanced spacesuits/miniships their whole live. Their cyborg opponents also can do that but don't need suits and looks mostly-human. He thought that members of research expeditions are cyborgs because of how they look and because they tried to extract him from the suit.]]
* In the ''Literature/{{Animorphs}}'' series, it's revealed that Andalites do not require space suits, instead simply wearing masks with a breathable gas that prevents decompression. It's... considerably less efficient for humans, and merely draws out the process of suffocation in space.
* Spider Robinson's ''Stardance'' novels wind up with humanity dividing into air-breathers and space-farers, through the consumption of some reddish gunk found in Titan's atmosphere. The spacers can live quite normally in vacuum with their biological symbiote/suits.
* Creator/DianeDuane's [[Literature/TheTaleOfTheFive Door into Shadow]] depicts dragons who are able to fly light-years through space without breathing.
* Creator/HPLovecraft's work features not one, but ''three'' alien species, not counting the famed Franchise/{{Cthulhu|Mythos}} himself, who are capable of flying through space completely naked. Cthulhu, the Byakhee and the Mi-Go may get a pass, since they're explicitly said to be extradimensional beings made of exotic matter, but the StarfishAliens known as the Elder Things are not. It is explained that they "absorbed certain chemicals" in preparation for their journey through space, though at least on Earth the required knowledge was later lost.
* In the sci-fi series ''Akiko'', this is handwaved hilariously when the eponymous character takes her first trip into space in a roofless shuttle--there's ''plenty'' of air in space!
* In Creator/JohnVarley's ''Literature/EightWorlds'' books and stories, wherein humanity has been driven from the Earth by enigmatic aliens and is forced to live on the other worlds of the Solar System, humans are often fitted with a portable force-field generator which operates automatically when they walk from pressurised to unpressurised areas. The force-fields merge when brought together so that people can embrace and make love in vacuum. Meanwhile, in the rings of Saturn, the Symbs are humans who live in symbiosis with biological, semi-sentient spacesuits. They spend their entire lives in vacuum, the symbiots providing them with all the oxygen they need and recycling their waste for nutrition via photosynthesis.
* In a novel from Literature/StarTrekTheLostEra, a Neyel transported aboard a ship after being blown out into space isn't quite dead after all; it turns out Neyel have engineered themselves to survive vacuum for a time. As is pointed out, they're not the only race who can survive space; mention is made of the Nasat, a nod to ''Literature/StarfleetCorpsOfEngineers''.
* In ''Franchise/StarWarsLegends'', the Givin race evolved on a world whose wacky lunar orbits regularly robbed areas of atmosphere. As a result the Givin developed an exoskeleton that doubles as a spacesuit. [[AWizardDidIt The Force Did It.]]
* In ''[[Literature/HorusHeresy Know No Fear]]'', Roboute Guilliman is vented into space and presumed dead. Several chapters later, he reappears none the worse for wear. The book explains that the ship carries thin layer of atmosphere around the hull to avoid decompression of hangars when shuttles come and go, which is why he survived. It helps that he's a SuperSoldier to the super-soldiers.
* In ''Literature/BookOfTheShortSun'', the alien [[OurVampiresAreDifferent Inhumi]] are supposedly able to fly unaided and unprotected between ''planets''. It is left as an exercise to the reader to decide whether this is actually possible, even in-universe.
* ''Literature/LandoCalrissianAndTheStarcaveOfThonBoka'' has the Oswaft, aliens who evolved in space and were perfectly happy there, absorbing enough loose atoms in a nebula to grow bigger than aircraft carriers. They could even do hyperspace jumps.
* Peter F. Hamilton's ''Literature/FallenDragon'' has some people encounter immense creatures engineered to serve as a kind of galactic library. They orbit red giant stars and live off the radiation and the matter in the solar wind.
* In ''Literature/ThePrideOfParahumans'' parahumans can survive without air for about an hour, ten minutes conscious. And they can function in vacuum with nothing more than a helmet for a long time. Their eardrums are still vulnerable to ExplosiveDecompression though.
* In ''Literature/ThePlatinumKey'' the characters can breathe in space in the Jumbo vortex, although the reason is unknown.
* In ''[[Literature/NightWatchSeries Twilight Watch]]'' by Sergei Lukyanenko, Kostya assumes that, being a very powerful vampire, he should be able to survive in space long enough to teleport to a space station and proceed with his plan. [[spoiler: He's wrong. Due to [[MagicAIsMagicA how magic works in the setting]], there's no magic in space.]]
* The last third of ''Literature/TheDivineComedy'' is entirely set in space and there's no mention that our very human protagonist has any problem breathing as he jumps off the Sun and flies to Mars. To be fair, this was written in 1324, so [=NASA=] didn't have the funding to correct Dante's error.
* In ''Marvin Wanted MORE!'', the titular sheep somehow manages to breathe in space in order to eat '''[[MakesJustAsMuchSenseInContext the entire Earth]]'''.
* In ''Literature/MyBrotherIsASuperhero,'' this turns out to be the intended purpose of Zack's SuperNotDrowningSkills.
* In ''Literature/DadAreYouTheToothFairy'', Gabi's dad claims that there used to be magical creatures, [[HereThereWereDragons but they had to leave]] "because of [[MagicVersusScience technology]]", and that they may have escaped to "the stars" or be living on the moon now.
* In the ''Literature/FairyOak'' series, Telli has been able to see the stars up close without a spacesuit (as these don't exist). Partly justified, as she is a fairy.

!!~@/{{crazysamaritan}}'s version
It is surprising how often you can find fictional characters capable of surviving the dangers of space travel, to the point where some leave Earth's atmosphere with only a glass dome for a helmet, and sometimes, not even that. They don't have a "can-breathe-in-space" power or a spacesuit. Someone forgot to tell the creators, but... SpaceDoesNotWorkThatWay, leaving this on the softer edge of MohsScaleOfScienceFictionHardness.

In RealLife, space is [[https://www.space.com/30066-what-happens-to-unprotected-body-in-outer-space.html dangerous]]. You won't [[ExplosiveDecompression explode]], but you will inflate as bubbles form in your bloodstream near the surface of your skin. You won't [[SpaceIsCold freeze to death]] exactly, but you will lose heat at the rate of 100 joules per second. Depending on how close you are to a star, radiation from high-energy wavelengths will cook you instead. People can theoretically survive in space for a minute or two, given medical assistance afterwards, as their body shuts down due to lack of oxygen. Of course, holding your breath doesn't help, as the internal pressure would tear your lungs. The story, however, is ignoring or downplaying these dangers, allowing fictional characters to survive long exposure without assistance.

Superpowers bring a different message. Already unrealistic, alien biology or metahuman abilities that could plausibly explain your survival negates this trope and thus are not examples. While it is surprising for {{Franchise/Batman}} to breathe in space (unless he's wearing a [[{{Hyperaffixation}} Bat-]]spacesuit), {{Franchise/Superman}} isn't an example because his survival can be [[{{Handwave}} excused due to Kryptonian durability and resistance to everything]]. Bruce Wayne, however, is wearing a mask attached to an oxygen tank and completely ignoring the realistic swelling and heating/cooling that would actually be occurring if someone [[JustForFun/TelevisionIsTryingToKillUs imitated it]].

{{Subtrope}} to TheNeedless, because the character is somehow protected from dangers that would be lethal to human beings, and to SpaceDoesNotWorkThatWay, because these outer space inaccuracies are in service of the story. Compare SpaceIsNoisy, where sound is conveyed via vacuum in the same way as sound is conveyed through atmosphere, allowing the characters to talk to one another. Contrast ExplosiveDecompression, where being exposed to a vacuum will quickly make you explode due to the air inside your body trying to expand and fill the void. Don't be surprised if the writers use both tropes in the same work.
----

* ''Animation/ThreeThousandWhysOfBlueCat'': When Blue Cat and Feifei get sent into outer space in the episode "Will Earth Be Destroyed?", they're able to talk to each other just fine without wearing helmets or space clothes.

----

* ''ComicStrip/CalvinAndHobbes'':

* In ''ComicBook/PowerGirl'' fanfic ''Fanfic/AForceOfFour'' Kryptonians and Hatorians don’t need to breathe. It becomes a plot point when the four villains have to relocate their Earthborn prisoners but can't move them to a place with no atmosphere.

* ''Everyone'' in ''FanFic/TheEndOfEnds'' can breathe in space.
* In ''ComicBook/{{Supergirl}}'' fanfic ''Fanfic/HellsisterTrilogy'', the Legionnaires can breathe in space thanks to their Flight Rings -and some of them like Supergirl because of their natural powers- but they still need additional devices to communicate with each other. Supergirl's ability to exist out of the boundaries of a planet comes up when she arrives in the 31st century.

* ''Fanfic/LastChildOfKrypton'': In this crossover Shinji thinks maybe he can breathe in space… sometimes he jokes about it… and later he confirms he ''can'', indeed. Because he is ''Franchise/{{Superman}}''.

* The same goes for another Kryptonian character in ''Fanfic/TheLastDaughter'', where [[Literature/{{Worm}} Taylor Hebert]] becomes Superwoman.
* In ''Fanfic/BringerOfDeath'' both Cooler (Frieza's brother, and as such has this ability) and Cell try and take advantage of this against Vegeta, only to learn that [[spoiler:Vegeta expected this and had put together a method to store oxygen in his lungs, with his Super Saiyan aura taking care of the other problems]].
* Invoked in ''Series/Supergirl2015'' story ''Fanfic/{{Survivors}}''. Before getting out of her rocket [[ComicBook/{{Supergirl}} Kara]] is worried about the alien atmosphere being breathable. She dares take a breath and confirms she can breathe in that atmosphere.
* In ''Franchise/{{Superman}}'' story ''Fanfic/SupermanOf2499TheGreatConfrontation'' Superman's Home Base is located within the asteroid Ceres. Superman can reach it because he doesn't need to breathe. He doesn't like the reminder, though, because it makes him feel less human.

* In ''Series/BuffyTheVampireSlayer''/''ComicBook/{{Supergirl}}'' fanfic ''Fanfic/TheVampireOfSteel'', Supergirl flies out of the atmosphere to get rid of an EldritchAbomination. Being Kryptonian, the space vacuum is not trouble at all.
* Sonic the Hedgehog's canon ability to breathe in space is justified in ''Fanfic/DescentIntoDarkness'' as being a trait of [[FunnyAnimal dokan]]. They absorb, and use, oxygen more efficiently than humans.
* Partway through [[Creator/DetsniyOffSkiword Dahlia Hawthorne Escaps From Pirson]], we see [[FloatingContinent Britain fly off into space]] [[MakesJustAsMuchSenseInContext as a result of Brexit]]. At no point does anyone in Britain, regardless of if they were already there or had just arrived to find out what’s going on, seem to have trouble with breathing or gravity or the like.
* ''Fanfic/ChildOfTheStorm'' has Asgardians and Kryptonians, who have no trouble surviving in space. As Harry's Asgardian heritage comes through, he is seen more than once hanging out in the upper atmosphere or space without any protective gear - though part of that might be his use of telekinesis.
* ''Fanfic/SundaySkivvies'', a fanfiction of ''WesternAnimation/TheLoudHouse'', has Luan ask why the comic book character Muscle Fish can breathe in space.
* In ''Fanfic/HereThereBeMonsters'', the various entities empowering [[ComicBook/{{Shazam}} the Marvel family]] or villains like Ibac and Sabbac grant their chosen ones the ability to survive with no atmosphere.

* In ''Fanfic/SnicNdTheOsrailianResrant'', Saniic jumps into space, touches the moon softly, and comes back down.
* Discussed in ''Film/ManOfSteel'' story ''Fanfic/DaughterOfFireAndSteel''. When the Black Zero crew arrives in Earth, they test the planet's atmosphere before going out of their ship to ascertain whether its air is safe to breathe.

* In ''WesternAnimation/JimmyNeutronBoyGenius'', all of the kids are seen sitting in open space multiple times without any equipment whatsoever. Also there's the fact that a fire can be built on a large asteroid and an airless area is apparently capable of conveying sound.
* In the ''Animation/PleasantGoatAndBigBigWolf'' film ''Moon Castle: The Space Adventure'', the gang goes to the moon to keep the Gourd King from making it bitter. They do not wear their spacesuits while on the moon, and yet they have no problems breathing there.
* In ''Animation/TheReturnOfHanuman'', Hanuman fought against Rahu and Ketu in outer space, with no space equipment whatsoever.
* This happens to Batman himself in ''WesternAnimation/SupermanBatmanPublicEnemies''. After the destruction of the Kryptonite meteor, Batman is trapped in what can only be described as a small airplane for several minutes in space, while Superman beats up the President. Finally, Superman gets around to rescuing his best friend, who is unconscious, but still alive.
* In ''WesternAnimation/TreasurePlanet'', everyone can breathe in space. No explanation; they just... ''can''. Chalk it up to RuleOfCool, since the whole movie treats space [[SpaceIsAnOcean like an ocean]]. Space is called "The Etherium". And there's all sorts of spaceborne organisms, like {{Space Whale}}s.

* The Xenomorphs from the ''Franchise/{{Alien}}'' franchise are capable of surviving in the vacuum of space.
* Inelegantly averted in ''Film/TwelveToTheMoon'' where NASA apparently coughed up the extra cash to replace the astronaut's faceplates with "invisible force-screens" that they make a point to mention before the crew steps out (read: They didn't want to fuss with trying to work camera lighting around proper helmets). Two of the astronauts notice the rubber gasket on their EverythingSensor moving.

* In ''Film/AirplaneIITheSequel'', after the Mayflower crash lands on the Moon, the passengers evacuate onto the surface without any breathing gear. Also, they can hear each other fine and there's apparently normal Earth gravity.
* Comically treated as the ElephantInTheLivingRoom in ''Film/AustinPowers: The Spy Who Shagged Me'', when Mini-Me's rescued unharmed some time long after he was sent spinning off into space.

* Near the end of ''Film/TheBlackHole'' the characters are inexplicably seen climbing from the Cygnus to the probe ship through the vacuum of space without space suits.
* Film/{{Gamera}} can breathe in space as well... he can fly too...

** ''Film/GuardiansOfTheGalaxy'' apparently operates by the principle that you can't ''breathe'' in space, but if you have some kind of respirator, you need no other protection from the elements. [[TheHero Peter Quill]] flies from the Kyln to the other Guardians in the ''[[CoolShip Milano]]'' in nothing but his civilian clothes and his [[CoolMask mask]], which doesn't even cover his hair. Similarly, Peter later [[spoiler:saves Gamora's life by coming out of his mining pod in space and giving her his mask, holding his breath long enough for TheCavalry -- in the form of his space pirate adopted family -- to come and get both of them]]. Neither suffer particularly ill effects given that they both spend about a minute in vacuum.
** ''Film/AvengersInfinityWar'': The Guardians are shocked to discover Thor floating in space, alive after having spent who knows how long in the vacuum without any protection. He's near death, but only due to injuries he received before being spaced. Later in the movie, he deliberately goes out without a space suit, and is none the worse for wear. He can even ''speak'' and ''pant'' in space, somehow.
** In ''Film/{{Captain Marvel|2019}}'', this is one of Carol's [[SuperpowerLottery many powers]].
* Parodied in ''Film/{{Spaceballs}}'', when Barf moves Princess Vespa to Lone Starr's ship, he just takes a ladder and climbs in her sun roof.
* In ''Film/StarTrekFirstContact'', Borg drones stroll across the hull of the Enterprise without environmental suits. Presumably, their internal replicators (mentioned in series episode "I, Borg") supply them with whatever gases they need. Perhaps whatever turns their skin gray also maintains their internal pressure.

** In ''Film/TheEmpireStrikesBack'', while they use breathing masks at the time, when Han, Leia, and Chewie venture outside the ''Millennium Falcon'' while hiding in what turns out to be a giant space slug, they don't seem to have any protection against decompression. One ''could'' assume the asteroid was large enough to have enough of some semblance of an atmosphere, or that the worm's innards are responsible.
** In ''Film/TheLastJedi'', a rebel ship gets blasted and Leia is sucked out into space. She is able to use the Force to pull herself back to an airlock. Downplayed as she then goes into a coma and needs life support for a while before recovering.

** During ''Film/SupermanII'', Zod, Ursa and Non ([[TheSpeechless well, him, not so much]]) had a lengthy conversation with each other about taking over the world whilst on the moon. As well as talking to an astronaut. Even if they could talk in space, he shouldn't be able to hear them through his air-tight helmet.
** Abused in ''Film/SupermanIVTheQuestForPeace'':

** In ''Film/ManOfSteel'', Superman briefly flies outside of Earth's atmosphere, despite the movie establishing that he needs to breathe. Although he might have been holding his breath.
* In ''Film/TheAdventuresOfBaronMunchausen'', the protagonists travel to the Moon via hot air balloon. Justified, as it's a MindScrew fantasy film and the Moon is depicted as a rather surreal place.
* In ''Film/MenInBlack3'' the antagonist Boris the Animal is a member of the boglodite alien species, and is able to survive in the vacuum of space, as shown in the movie's opening in which he escapes from a prison on the Moon by blasting a hole through a wall causing a [[ThrownOutTheAirlock huge decompression]] that kills everyone else.
* The silent film ''Film/WomanInTheMoon'', despite being one of the few early sci-fi movies where the creators paid attention to technical accuracy. This was because silent film actors depended greatly on facial expressions and body language [[InSpaceEveryoneCanSeeYourFace which would be obscured by bulky spacesuits and helmets]].
* ''{{Film/Avatar}}'': Colonel Quaritch runs out of the building protecting humans from Pandora's toxic atmosphere to shoot at the fleeing heroes. ''Then'' one of his (suited-up) soldiers gives him a gasmask.

* Franchise/{{Batman}} does this in one of the early issues of ''Comicbook/JusticeLeagueInternational'' [[spoiler:(granted, it was due to the New Genesis-created training satellite's programming directive to not actually harm its opponents, thus causing it to create an artificial atmosphere when Bats's space helmet gets broken, but all the same)]]. One issue of ''Franchise/JusticeLeagueOfAmerica'' showed Batman training himself, not to be able to breathe in space, but to at least survive the vacuum of space for a couple of seconds. The Comicbook/MartianManhunter helps while wondering if he should.
* During the ''Trial By Fire'' storyline of ''Franchise/{{J|usticeLeagueOfAmerica}}LA'', Comicbook/{{Firestorm}} finds himself out on the moon, breathing normally. Then, he is attacked and transformed back into Ronnie Raymond. He is immediately unable to breathe or function, and it is only Flash's assistance that saves him.
* Franchise/{{Superman}}, in UsefulNotes/{{the Silver Age|OfComicBooks}} version.

* ''ComicBook/WonderWoman1942'': Speaking of Franchise/WonderWoman, her [[UsefulNotes/TheSilverAgeOfComicBooks Silver Age]] version had ''earrings'' to provide life support in space by creating a "transparent envelope" (apparently "bubble" was too undescriptive). Since she was also sculpted from clay and brought to life through magic it is entirely possible she does in fact not need oxygen to survive.
* In ''ComicBook/XMen: What If Stryfe Killed Apocalypse'', (somewhat before ''Fatal Attractions'', set during the events of ''X-Cutioner's Song'') it is demonstrated that vacuum is one of the things which will, in fact, kill Wolverine. If that were to happen today, he'd barely blink an eye...
** Speaking of ''X-Cutioner's Song'', there's one scene where Cyclops and Jean Grey escape one of Stryfe's fortresses and attempt to get away by ''crawling across the moon''. Not only do they survive that brief point of time before they ''pass out''. That's also counting the fact that there's also probably enough gravity that Jean can take a misstep and promptly faceplant onto the moon's surface and get a bloody nose.
* Apollo of ''ComicBook/TheAuthority'' works this way. At one point he is asked how he operates in space, and responds that he just doesn't breathe. "Just like that?" "Well, I'd look pretty stupid if I tried to breathe in space, wouldn't I?" [[ItRunsOnNonsensoleum That's all the (non-)explanation we get]].

** The Legionnaires wear "transuits", essentially [[LatexSpaceSuit skin-tight, invisible space suits]] that somehow provide all the protection they need. So, it just ''looks'' like they're all breathing in space. In the cartoon series, it was explained away as one of the properties of the [[AppliedPhlebotinum flight rings.]]
** Justified in ''ComicBook/TheGreatDarknessSaga'' when a Servant of Darkness destroys a Legion Cruiser going on an interplanetary trip. White Witch casts a force protective shield spell around her and her Legion teammates to keep the oxygen and warmth in and the cold and radiation out as waiting for a rescue team.
* In ''Comicbook/{{Watchmen}}'', Dr. Manhattan doesn't need to breathe, and momentarily forgets that ordinary humans ''do'', he then provides Silk Spectre with a Legion style invisible forcefield. Mars is only slightly more human friendly than space.
* In ''ComicBook/{{Invincible}}'', any Viltrumite (plus Allen the alien) can survive in space so long as they hold their breath. Which apparently is a very long time. Long enough to cross interstellar distances without a spaceship.
* In an issue of ''Comicbook/MarvelStarWars'' Vader survives an assassination attempt via opening airlock, since he has a life-support suit; the officers who attempted the assault [[HoistByHisOwnPetard get sucked out instead]].
* The ''Comicbook/FantasticFour'' just use helmets-- their [[MySuitIsAlsoSuper uniforms]] double as spacesuits (except ComicBook/TheThing, his skin is tougher than any spacesuit) -- the [[http://en.wikipedia.org/wiki/Space_activity_suit Space Activity Suit]] was still several years away from invention when the FF started this practice.
* In ''Comicbook/PS238'', they take a class excursion to the moon. The various superkids require various levels of protection, and Captain Clarinet (the son of a Superman CaptainErsatz) has some trouble explaining that he DOES, in fact, need to breathe, and thus goes up wearing a breathing-apparatus. (He still has no trouble with the radiation, temperature, or general vacuum-ness, though.) Then [[Franchise/GreenLantern Emerald Gauntlet]] Jr. reveals that his [[GreenLanternRing Gauntlet]] can both provide a protective force-field AND gather oxygen-atoms from the surroundings to allow him to breathe. "I'm cool that way", as he puts it. Then he winds up marooned on the moon along with a few other students, including the EvilGenius Zodon, and suggests that he could just ferry them all back to Earth with his Gauntlet... only for Zodon to explain that, while he can probably gather enough oxygen to maintain breathing on the moon (the moon's consists of approximately 40% oxygen, though most of it is bound to silicon), the same cannot be said for interplanetary space.
* ''Comicbook/{{Empowered}}'' discovers this by ''accident'' [[spoiler:when she steps on to an airless asteroid from a malfunctioning portal]]. Then again, her supersuit [[HowDoIShotWeb didn't come with instructions]].
* If you're a comic book character simply ignoring physics is a valid option: in ''Trinity'', Despero leaps out of his armada flagship to fight Green Lantern in space, when his lackey objects saying he has no space suit on, Despero merely shouts "Air is for cowards! Do it!" and he actually survives perfectly fine.
* In the ''Comicbook/SamAndMaxFreelancePolice'' episode, "Bad Day On The Moon", the eponymous duo blast off to the moon (via thousands and thousands of match heads stuffed into the [=DeSoto=]'s tailpipe) with only a set of penny-conscious moon gear (paper bags with plastic eye holes to put over their heads) to protect them from the lack of atmosphere on the moon. But, despite Sam's preparedness (he brought a spare bag in case he ran out of air), it turns out that they can breathe easily on the moon, as Max exemplifies by taking his bag off to dig some moon dust out of his eye. Explained thusly:

* The Comicbook/PostCrisis Comicbook/CaptainAtom originally couldn't breathe in space, and once, when an enemy teleported him to the outer solar system, he had to fly back to Earth while holding his breath, which he could only do for a normal amount of time. Later on, though, he learned to use his powers to create and manipulate matter to keep his lungs filled with air indefinitely, so he could stay in space as long as he wanted.
* In ''Comicbook/InfiniteCrisis'', Superboy Prime jaw jacks with the entire Green Lantern Corps. In space. The Corps. are protected by their rings of course. When Earth 1 & 2 Supermen tackle Superboy Prime, they hold their breath while Prime keeps insulting them and throwing punches casually, until they throw him through the red sun of Krypton and fly him right into Mogo, a Planet that just happens to be a Green Lantern. Comics are weird.
* SelfDemonstrating/{{Lobo}} can breathe, talk and ''[[BeyondTheImpossible smoke a cigar]]'' in space. Of course, Lobo lives and breathes BeyondTheImpossible.
* The Comicbook/IncredibleHulk can breathe and survive in the vacuum of space.
* Comicbook/TheMightyThor plays this fast and loose. It's not specifically stated that he doesn't need to breathe, but he is shown surviving in space for short periods. The writers probably thought "He's a god, so [[AscendedFanon why not]]? It's long since been confirmed that Thor can survive perfectly fine in space, considering he [[spoiler: went round for round with the Phoenix Force (the entity itself, not the host) in deep space wearing nothing but his normal sparkly pants]].

* In ''ComicBook/CerebusTheAardvark'', during Cerebus' time on the Moon with the Judge at the end of ''Church and State II'' and the extensive "trek through the solar system" section in the last quarter of ''Minds'', Cerebus and other characters have no space-faring gear of any sort.
* In ''ComicBook/TheSupermanAdventures'', an aversion becomes a plot point. Superman deals with Krypto, gone berserk because [[SensoryOverload he can't handle the stimulation]], by briefly spacing him, knocking him unconscious.
* In the second story-arc of ''ComicBook/MyLittlePonyFriendshipIsMagicIDW'' the lack of oxygen doesn't seem to be an issue on the moon. The princesses did bring the moon closer first, so it could just be within the planet's atmosphere, but that wasn't the reason they gave for doing it.
* ''ComicBook/{{Shakara}}'': Downplayed. The Shakara were so resilient that they could withstand the vacuum of space for long stretches of time (whereas most other species will promptly [[ExplosiveDecompression explode]]), but apparently not indefinitely.
* In ''ComicBook/SupermanAmericanAlien'', a young and inexperienced Superman attempts to fly to the moon. He learns the hard way that while his invulnerability lets him survive a vacuum, he still needs to breathe. He almost dies before he manages to fly back to Earth.
* ''ComicBook/UltimateVision'': Vision and Dima are both artificial beings, so of course they can survive the vacuum of space and simply leave the doomed satellite.

* Herman Li and Sam Totman of Music/DragonForce on an asteroid in [[https://www.youtube.com/watch?v=WrSG8p-iBTo this]] ad for Capital One. Presumably, they are protected by ThePowerOfRock.
* A Creator/{{PBS}} promotion for ''Series/SesameStreet'' briefly has Big Bird and a five-year-old girl on the Moon during the Apollo landings with no protection whatsoever.

* In ''Manga/{{Akira}}'', Tetsuo flies into space to blow up an [[KillSat orbital space laser]]. He's shown projecting an energy field around his body, presumably to protect against the vacuum of space. He also seemingly has no trouble breathing without an air supply.

* In ''LightNovel/ACertainMagicalIndex'': ''Miracle of Endymion'', Kaori Kanzaki does not need a space suit while everybody else does. She is a Saint and therefore much tougher than an ordinary human. She was also surrounded by a magical energy field.
* In ''Manga/ACertainScientificRailgun'', Mikoto and Kuroko are launched to the edge of the atmosphere to deal with an approaching missile. They are not bothered by the vacuum, but could not breathe and had to work fast so Kuroko could teleport them back to Earth before they suffocated.
* ''Anime/DigimonFrontier'': Late on the series, our heroes end stranded in ''a'' moon, and there's no air problems. A FanSub actually {{lampshade|Hanging}}d this. Then again, they're in the digital world. Everything is made of data, so real-world physics don't apply.
* ''Anime/{{Doraemon}}'': Doraemon has pocket gadgets that allows one to breathe in space without a suit.
* In ''Franchise/DragonBall'', Son Goku uses his power pole to drop the rabbit-like Carrot Master and his thugs off on the moon. Neither Goku making the trip or the moon bound gang members suffer any ill effects likely due to [[ToonPhysics anime physics]].

* ''Manga/GalaxyExpress999'': Tetsuro is baffled to hear the sound of distant church bells as the 999 approaches a planet. Its inhabitants are so arrogantly pious that they have gravitational wave emitters which broadcast an intense graviton carrier wave which induces the sound of distant church bells in passing ships. Impressed, Tetsuro rolls down the window and sticks his head out to get a better look. [[note]]TheAestheticsOfTechnology is part of the setting -- Technology has advanced so far that spaceships can be built to look like steam locomotives, so for all we know, there's a forcefield HandWave protecting Tetsuro.[[/note]]
* ''Anime/GaoGaiGar'': Guy Shishioh has survived in space without a space suit, but he was a cyborg at the time, later on, when he [[spoiler:becomes an evoluder]], he no longer needs anything to survive in space. Mamoru and Kaidou both can fly and survive for long periods in space un-aided, even while unconscious!
* [[spoiler:Nami]] from ''Anime/TheGirlWhoLeaptThroughSpace'' can breathe and move through space fine when her SuperpoweredEvilSide is around.
* ''Anime/GlassFleet'': unless it's relevant to the plot that they don't, it's safe to assume that humans can breathe in space. There's only one time where it's relevant.
* The highly evolved Silver Tribe in ''Anime/HeroicAge'' have this ability, as do the Nodos. Then again, the former can create matter out of nothing and the latter are giant superpowered space monsters in human form.
* On the last episode of the ''Anime/KaitouTenshiTwinAngel'' anime, the girls fly off to space via pure willpower to destroy a KillSat. They're also shown surviving re-entry into the atmosphere fine. Oddly, despite all her complaints of "How do we go to space?" and "How do we come back from space?", Kurumi never asks how are they breathing in space.
* ''Anime/KiddyGrade'' and ''Anime/KiddyGirlAnd'' have multiple examples of characters breathing in space, handwaved by the ubiquitous nanomist technology.
* The final battle of ''Anime/KillLaKill'' takes place in space. Neither of the fighters is technically human, as they are rather hybrids of human and Life Fiber, the resident alien menace, so them easily surviving the vacuum of space could be justified. Being able to talk, less so; but this being a Trigger show that basically runs on RuleOfCool it's probably better not to think too hard about it.
* ''Anime/KotetsuJeeg'': Shiba Hiroshi, justified because he ''is'' a cyborg. It's pointed out in the sequel ''Kotetsushin Jeeg'', when he opens the hatch on his cockpit when they're on the moon and steps out.

* In ''Anime/KurauPhantomMemory'', Christmas and Kurau pull this off when their space ship gets blown up.

** That scarf Hikaru/Rick used early on in ''Anime/SuperDimensionFortressMacross''[=/=]''Anime/{{Robotech}}'' must have been some kind of awesome to have let him survive out there in space. Unless... this trope.
*** Possibly with a side order of ScienceMarchesOn and ArtisticLicense, as the episode establishes that Hikaru ''was'' holding his breath while out in hard vacuum, which as mentioned above is '''not''' a good idea if you're exposed to it... Seriously, the greater issue was he was in an unpressurized, and not thermally insulated, flight jumpsuit. [[ComicallyMissingThePoint And how did the tuna not get freezer burn, anyway?]]
** The Zentraedi cannot actually breathe in space, but they're designed to have a greatly increased resistance to vacuum. Breetai gets ThrownOutTheAirlock at one point, but then spends a minute or two crawling around outside the ship and jumps back in with no ill effects. In ''Anime/MacrossFrontier'', Ranka gets exposed to vacuum briefly, and is unhurt, which she chalks up to her quarter-Zentran ancestry.
** The Protodeviln from ''Anime/{{Macross 7}}'' are all able to survive in vacuum with no protection, being genetically engineered superweapons for space combat. They also display the ability to protect others from the effects of vacuum by shielding them in some sort of energy field.
* The final battle of ''Anime/MagicalGirlLyricalNanohaDetonation'' takes place in low Earth orbit, and Nanoha is not only able to breath but is able to talk to her opponent. Presumably, her [[InstantArmor Barrier Jacket]] handles all those pesky issues like a lack of breathable atmosphere and harmful radiation.
* Everyone in the ''Anime/TenchiMuyo'' {{O|riginalVideoAnimation}}VAs appears to be able to breathe in space. This is probably the least strange thing about space in that series, so it doesn't stand out too much. The characters in the lower power-tier require spacesuits, but since they use hyper advanced technology, they don't look much to the part -- invisible forcefields instead of helmets, and so on. Ayeka, Tenchi and Mihoshi all wear such suits early in the anime, but later Tenchi stops using his, due to realizing the power of the Light Hawk Wings. Usually {{handwave}}d by the fact that those who have any significant importance in Kajishima's canon are explicitly said to be {{Physical God}}s and thus technically ''don't need'' to breathe.

* ''Anime/MaiOtome''. Some fans have tried to justify it by saying "Otome can breathe in space," but nanomachine enhancements would not change the fact that "[[VideoGame/{{Gauntlet}} Otome needs oxygen badly!]]" In the OVA Arika even takes the completely-normal Mashiro ''with her'' (for a sight-seeing tour of the world... no seriously, that's exactly what she says).

* ''Manga/MissKobayashisDragonMaid'': Tohru has demonstrated the ability to go into orbit (or at least the upper atmosphere) without any form of space suit. It's unclear if she was using magic to protect herself.
* In ''[[Anime/TheLastNarutoTheMovie Naruto The Last]]'', Naruto's fight against [[BigBad Toneri]] on the moon definitely qualifies.
* Kaworu in ''Anime/RebuildOfEvangelion'' doesn't need a spacesuit in space.
* In ''Anime/NGKnightLamune40'', the Doki-Doki Space seems to have air, which is because everyone can breathe and talk freely.
* The heroes from ''Anime/NightWizard'' can move around in the moon with no problem whatsoever, and with no need of air either. Because [[AWizardDidIt they're wizards]].
* [[AGodAmI Eneru]] from ''Manga/OnePiece'' flew to the moon following his defeat and had no trouble walking around in just awesome pants. He ''is'' living lightning after all. That, and the Manga/OnePiece [[TheVerse 'verse]] has only the vaguest resemblance to RealLife physics.
* ''Webcomic/OnePunchMan'': [[ComicallyInvincibleHero Saitama]] was once punched to the Moon, and had no problem relaxing there briefly before jumping right back.
* Near the end of ''Anime/PuellaMagiMadokaMagica'', Homura gets stuck on the moon for a few minutes, and has no difficulty breathing or talking. There's no explicit explanation of how she can breathe or even how she got there, though it [[AWizardDidIt presumably has something to do with]] [[spoiler:Madoka paradoxically destroying her own witch and rewriting the universe]].
* Not only can Franchise/SailorMoon breathe in space, she can even survive re-entry [[spoiler:or rather, [[AllYourPowersCombined she and the rest of the team together]] can power the Silver Imperium Crystal enough to generate a heat and braking shield that just barely manages the job]]. Then again, she is a MagicalGirl. In the manga they can just jump into orbit, breathe in space, and survive re-entry with ease.
* The titular Symphogear users from ''Anime/SenkiZesshouSymphogear'' not only breathe in space but they also have no problem talking or ''singing'' there. Handwaved as a telepathy from the gears' powers.
* A number of characters in ''Manga/SgtFrog'' get away with this. Lampshaded in the Funimation dub, when the narrator complains about Space Police Officer Poyon walking around unprotected in space at the start of episode 11.
* ''Anime/SonicX'':

* In ''Anime/StarBlazers[=/=]Space Battleship Yamato,'' our heroes can turn their regular uniform into a spacesuit just by putting on a helmet. This often leaves their neck or the back of their driving-glove-clad hands open to space, which realistically would produce massive bruising at best.

* In ''Anime/{{Tamagotchi}}'', a human girl named Tomomi is at one point teleported to Tamagotchi Planet by accident and has no problems breathing in the planet's atmosphere. This isn't the only time in the franchise it's happened, either - in ''Anime/TamagotchiTheMovie'', another human girl named Tanpopo is accidentally transported to Tamagotchi Planet and doesn't have any trouble breathing there either.
* ''Anime/TengenToppaGurrenLagann'', but by the time we see people breathing in space, there are [[ShockingMoments things so much crazier]] that it's easy to overlook.
* ''Manga/TowardTheTerra'': Jomy and Soldier Blue can both breathe in space (and the initially-thin atmosphere of Naska), although this is attributed to their hyper-advanced PsychicPowers. Other Mu don't seem to have this ability.
* In ''Manga/UQHolder'':

* ''Anime/YesPrettyCure5'': The Pretty Cure 5 were able to fight on the moon without any problems. Presumably they consulted Sailor Moon on proper breathing-in-space technique.

%% ** Vegeta and Nappa are shown to be able to breathe in space, even though Frieza later claims that Saiyans cannot.

Either that or energy manipulation to create an environment for resistance.
%%*** Cell, having Frieza's cells ([[LegoGenetics Yeah...]]) can probably do the same thing, and does so in {{filler}}. The various forms of Majin Buu also have no problems moving around in space, nor does Baby from ''[[Anime/DragonBallGT GT]]''. Seems to be a trend across ''Dragon Ball'' villains.
%%** Also, during the fight between Bardock and Frieza, Bardock is just floating in space kicking butt (or is at least in the outer atmosphere).

Find yourself in space without a spacesuit? Not a problem! Those supposed hazards of the "unforgiving" vacuum of space just never show up. Ordinary people can breathe just fine in space, and you can take a spacewalk in your underwear if you don't mind being a bit [[SpaceIsCold chilly]]. For those worried about oxygen, the most you'll need is an oxygen mask, but an upside-down fishbowl on your head will often do in a pinch. You don't need a "can-breathe-in-space" power, it doesn't need to be explained, and you ''certainly'' don't need a spacesuit. It makes you wonder why astronauts bothered with them in the first place.

In RealLife, space exposure is dangerous. Suffocation is the greatest concern, followed closely behind by your internal fluids boiling away due to the low pressure and radiation from high-energy wavelengths that the atmosphere normally absorbs. People can theoretically survive in space for a minute or two, given medical assistance afterwards. It is actually recommended to ''not'' hold your breath, as the internal pressure could cause your lungs to rupture.

Superpowers bring a different message. This trope is about unjustified resistance to space exposure; if a character has powers that could plausibly give them resistance, then it's not this trope. While it is surprising for {{Franchise/Batman}} to breathe in space (unless he's wearing a [[{{Hyperaffixation}} Bat-]]spacesuit), {{Franchise/Superman}} isn't an example because his survival can be [[{{Handwave}} excused due to Kryptonian durability and resistance to everything]]. Bruce Wayne, however, is wearing a mask attached to an oxygen tank and completely ignoring the realistic swelling and heating/cooling that would actually occur if someone [[JustForFun/TelevisionIsTryingToKillUs imitated it]].

{{Subtrope}} to TheNeedless, because the character is somehow protected from dangers that would be lethal to human beings, and to SpaceDoesNotWorkThatWay, because these outer space inaccuracies are in service of the story. Compare SpaceIsNoisy, where sound is conveyed via vacuum in the same way as sound is conveyed through atmosphere, allowing the characters to talk to one another. Contrast ExplosiveDecompression, where being exposed to a vacuum will quickly make you explode due to the air inside your body trying to expand and fill the void. Don't be surprised if the writers use both tropes in the same work.

A work featuring this trope falls on the softer edge of MohsScaleOfScienceFictionHardness.

Find yourself in space without a spacesuit? Not a problem! Those supposed hazards of the "unforgiving" vacuum of space just never show up. Ordinary people can breathe just fine in space, and you can take a spacewalk in your underwear if you don't mind being a bit [[SpaceIsCold chilly]]. For those of you with a crippling addiction to oxygen, the most you'll need is an oxygen mask, but an upside-down fishbowl on your head will often do in a pinch. You don't need a "can-breathe-in-space" power, it doesn't need to be explained, and you ''certainly'' don't need a spacesuit. It makes you wonder why astronauts bothered with them in the first place.

In RealLife, space exposure is serious business. Suffocation is the greatest concern, followed closely behind by your internal fluids boiling away due to the low pressure and radiation from high-energy wavelengths that the atmosphere normally absorbs. People can theoretically survive in space for a minute or two, given medical assistance afterwards. It is actually recommended to ''not'' hold your breath, as the internal pressure could cause your lungs to rupture.

May be related to SuperNotDrowningSkills and HarmlessFreezing, since breathing while underwater or in a solid block of ice isn't really a big deal either.

Often a form of ArtMajorPhysics. Naturally, SpaceDoesNotWorkThatWay. When characters aren't just hanging out but ''talking'' in the great vacuum, you have SpaceIsNoisy. A form of TheNeedless. If ''everyone'' can do this, it's probably because SpaceIsAir. This trope is about unjustified resistance to space exposure; if a character has superpowers that could plausibly give them resistance to it, then it's justified and doesn't belong here. Compare ExplosiveDecompression, the opposite yet equally unrealistic depiction of vacuum exposure.

It is surprising how often you can find fictional characters capable of surviving the dangers of space travel, to the point where some leave Earth's atmosphere with only a glass dome for a helmet, and sometimes, not even that. Someone forgot to tell the creators, but... SpaceDoesNotWorkThatWay, leaving this on the softer edge of MohsScaleOfScienceFictionHardness.

In RealLife, space is [[https://www.space.com/30066-what-happens-to-unprotected-body-in-outer-space.html dangerous]]. You won't [[ExplosiveDecompression explode]], but you will inflate as little bubbles in your bloodstream form near the surface of your skin, called ebullism, but that won't kill you first. You'll grow cold as you radiate heat away from your body (not as quickly as when in water, due to [[ConvectionSchmonvection lack of convection/conduction]]), at the rate of 100 joules per second. But don't worry, [[SpaceIsCold you won't freeze to death]] first. While radiating heat, you'll also be pelted by solar and cosmic radiation, getting a deadly suntan, and ''still'' not what kills you first. Without the ability to breathe, your circulatory system will keep trying to bring the nonexistent oxygen from your lungs to your brain, putting it in starvation mode less than 15 seconds out of the airlock. Of course, taking a big gulp of air just before exposure is ''also'' a bad idea, as it will cause the fatal embolism mentioned at the start of this paragraph. Thus, you're dead due to oxygen starvation in under two minutes. These dangers, however, are ignored or downplayed to ridiculous levels, allowing fictional characters to survive long exposure without the normally required assistance.

{{Subtrope}} to TheNeedless, because the character is somehow protected from dangers that would be lethal to human beings, and to SpaceDoesNotWorkThatWay, because these errors in the science of outer space are used to tell the story.

Don't be surprised if the writers use both tropes in the same work.

Find yourself in space without a spacesuit with an oxygen tank? Not a problem! Breathing in the vacuum of space is just as easy as breathing on Earth, especially if you are a superhero or somehow able to leave the atmosphere under your own power. If you aren't, a mask tightly wrapped around your mouth and nose might be all you will need.

It should also be noted that the Milky Way does have an extremely thin "atmosphere", the interstellar medium, held in place by the gravity of all of the material in the galaxy, but it's far too thin to do a living Earth creature any good (typical densities of the ISM are about 1 atom per cubic centimeter; the air you are breathing is about 10^19 -- ''ten billion billion'' times more dense).

This trope often overlaps with SpaceIsAir, the assumption that since you can't see air and you can't see space, they must be functionally identical, and with SpaceIsNoisy, where sound is conveyed via vacuum in the same way as sound is conveyed through atmosphere.
