* ''WesternAnimation/StarWarsRebels'': In the first two seasons, Ezra Bridger spends a ''lot'' of time crawling around in ducts. The fact that he's a scrawny, underfed teenager helps a great deal. By Season 3 he's had a growth spurt, so he can't do this anymore.

** ''VisualNovel/PhoenixWrightAceAttorneyDualDestinies'' gives us a variant - Apollo suggests that someone walked through an air vent, but investigating the thing later shows that while it was possible, it was certainly not done and he has to come up with another defense.

*Averted in ''Fanfic/TheKeysStandAlone: The Soft World''. George talks about maybe navigating the air ducts to get to Mevaryat's basement room in the concert hall, but he isn't thrilled about the idea because he has no idea where the things go, and can't really navigate the larger world [[VoluntaryShapeshifting when he's something small]] anyway. Later, he finds out that the Tipaanese anticipated he might go in that way and set traps throughout the air ducts. Too bad for them he found a different way to get into the room.

* ''Series/{{The 100}}'' has Bellamy repeatedly use air vents to get around in Mount Weather without being seen. Possibly {{justified|Trope}} since Mount Weather is a large facility that needs a huge air filtration system to filter out radiation from the surface; if any place is going to have person sized air vents, it'd probably be them.

* To this day, criminals will attempt this trope at any number of buildings where they can find a suitable opening. The difficulty they will encounter is that ducts don't stay the same size or shape all that often. The added difficulty of straight up-and-down ducts will see many criminals slipping and falling to become wedged or even killed by the fall. Even worse for some criminals is they may attempt this on holidays or weekends to avoid being heard clambering through the ventilation. When they become trapped, they must wait days without food or water in extremely uncomfortable positions for somebody to discover them.
** Given that some buildings are closed for months at a time (if not permanently), it's not surprising that several unlucky burglars have ended up ''starving to death'' before being found.

* {{Justified|Trope}} in ''Manga/FullmetalAlchemist'': shrimpy Edward is the only character who can fit in the air vents, and for him it's a tight fit. Which leads to further comedy as Ed has a complex for being TheNapoleon.
* Like the opening of season 1, the opening of season 2 of ''Anime/GhostInTheShellStandAloneComplex'' is all about showing off the awesome skills of Section 9 while providing a reason for the unit's reactivation. The regular SWAT unit attempts an assault on the Chinese embassy through the air vents, but spectacularly fails with one officer dead and another being added to the terrorists' hostages. Seeing these poor results, his superiors immediately give Aramaki the green light to send in his team and get the job done.
* ''Anime/NeonGenesisEvangelion'': Asuka, Rei, and Shinji were forced to use this route to get into the Geo-Front during a power outage when none of the doors would open. The air vent entrance also {{lampshade|Hanging}}d the MaleGaze when Asuka kept kicking Shinji for "looking ahead." Later in the episode, we are treated to the sight of ''HumongousMecha'' escaping via (humongous) air ducts. The geofront itself is an immense underground open space, hence the need for extremely large duct shafts to the surface to keep the air fresh.
* Mokuba Kaiba once escaped from the Big 5 this way in ''Anime/YuGiOh'' At least he's a fairly small kid, more likely to fit and all that.
* In ''Manga/YuGiOhR'', Jounouchi and Honda avoid some {{Mooks}} this way. Lampshaded by Jou, who complains about how claustrophobic it is and keeps getting accidentally kicked in the face by Honda.
* {{Subverted|Trope}} with glee in ''Anime/{{Mnemosyne}}'': Slender (though busty) ActionGirl Rin Asougi decides to infiltrate an empty research laboratory by going through the ducts. She predicts the [[LaserHallway lasers]] and makes them visible by filling the cramped ventilation duct with smoke from a cigarette, and then proceeds to slip under the lasers... until her butt catches the laser, setting off all the alarms. Cue Rin's capture and... {{Squick}}.

* In the made-for-TV WesternAnimation/FelixTheCat cartoon "A Museum, The Professor and Rock Bottom", [[DumbMuscle Rock Bottom]] tries to escape from Felix in the art museum by using this tactic. It doesn't work, because not only can Felix clearly hear him travelling through the air conditioning vent, the vent is so small that Felix [[TravelingPipeBulge can see Rock's burly form squeezing its way through]]. He forces Rock out by setting the temperature so low, that Rock slides out the vent, frozen solid in an ice cube.
* ''Franchise/{{Transformers}}''
** ''WesternAnimation/TheTransformers'' episode "The Ultimate Doom, Part 2" introduced ventilation ducts large enough for Transformers to stand inside. Spike, Bumblebee & Brawn go through a ventilation shaft that takes them to Decepticon HQ. They're on Cybertron, where everything is of the same scale as Transformers are to humans, but why would they need air anyway?
** And pulled again in ''WesternAnimation/TransformersAnimated'', episode "Decepticon Air". Optimus Prime crawls through the ducts (it seems to be a squeeze, letting him homage ''Film/DieHard'' as well) of a spaceship -- maybe the air circulates to keep the energon from heating up and getting unstable? He does use it as a makeshift bomb, after all.
** ''WesternAnimation/BeastWars'': Cheetor goes through the ventilation shafts of the Predacon ship after having been accidentally transported to ''The Darksyde'' in "Equal Measures".
* This is a favorite route of the girls in ''WesternAnimation/TotallySpies'' for breaking in, clearly thanks to MaleGaze.
** Also done in the spinoff ''WesternAnimation/TheAmazingSpiez'' though vaguely more realistically due to the characters being 13 (Lee), 12 (Marc and Megan) and 11 (Tony). Even more plausibly the character seen doing this the most is Tony who, due to his young age, would realistically fit.
* ''WesternAnimation/KimPossible'' and Ron infiltrated this way in TheMovie. They do it quite a lot during the series.
* ''WesternAnimation/{{Recess}}'': T.J. often uses this route to break himself and occasionally others out of detention.
* ''WesternAnimation/TeenTitans''
** Exception; Titans Tower's quarantine lock-down system apparently ''does'' seal off openings to the air ducts, as seen in the episode "Haunted". (Robin got into the vents anyway....)
** Subverted in the same series: Cyborg is attempting an Air Vent Infiltration in the episode "Wavelength" when the walls roll up and the thing rotates, dumping him into an arena and a battle with Bumblebee which he very nearly loses. He should've thought twice about even coming across a vent ''big enough'' for his 6-foot, 200-pound chassis.
* ''WesternAnimation/{{Ben 10}}'' did this a couple times, though it's {{Justified|Trope}} by the fact that, both times, Ben was transformed into an alien form that was five inches tall and gave him greatly enhanced brainpower.
* In a ''WesternAnimation/{{Jem}}'' episode, Jem, Aja, and Shana do this to escape a locked room.
* ''WesternAnimation/SpiderManTheAnimatedSeries'' constantly had Spidey doing this. During the Venom arc, after Peter finds the symbiote and experiences drastic changes to his personality, he considers but chafes at using the trope, saying "That's the old Spidey talking." He instead goes for the direct approach: kicking the steel door down and barging into Kingpin's meeting.
* Peter and Brian do this in an episode of ''WesternAnimation/FamilyGuy'', complete with a ShoutOut to ''Film/DieHard''. They don't make it all the way in stealthily, though, Peter's large girth causes the vent to give out and dump them right in the middle of the prom.
* ''WesternAnimation/{{Futurama}}''
** Subverted: Fry and Bender try to escape from a brig through a steam pipe vent. Unfortunately, the steam pipe is full of steam. At least they got a good sauna out of it.
** {{Lampshade|Hanging}}d in ''[[TheMovie Bender's Big Score]]''. While trying to destroy a [[Franchise/StarWars "Death Star"]], Al Gore's head in a jar flies a through an air vent actually ''labeled'' "Achilles' Vent", lasers a-blasting, successfully destroying it.
** In ''[[TheMovie Bender's Game]]'', Fry and the other travel around [[BigBad Mom's]] factory through a tube that sends chickens to the enslaved Nibblonians. It works, but they have to shove their way through a lot of chickens.
* {{Lampshade|Hanging}}d and subverted in an episode of ''WesternAnimation/BuzzLightyearOfStarCommand'', when Emperor Zurg chews out the designer of his latest evil lair for making the air ducts big enough for heroes to fit through.

** Also done in the spinoff ''WesternAnimation/TheAmazingSpiez'' though vaguely more realistically due to the characters being 13 (Lee), 12 (Marc and Megan) and 11 (Tony). Even more plausibly the character seen doing this the most is Tony who, due to his young age, would realistically fit.
* ''WesternAnimation/KimPossible'' and Ron infiltrated this way in TheMovie. They do it quite a lot during the series.
* ''WesternAnimation/{{Recess}}'': T.J. often uses this route to break himself and occasionally others out of detention.
* ''WesternAnimation/TeenTitans''
** Exception; Titans Tower's quarantine lock-down system apparently ''does'' seal off openings to the air ducts, as seen in the episode "Haunted". (Robin got into the vents anyway....)
** Subverted in the same series: Cyborg is attempting an Air Vent Infiltration in the episode "Wavelength" when the walls roll up and the thing rotates, dumping him into an arena and a battle with Bumblebee which he very nearly loses. He should've thought twice about even coming across a vent ''big enough'' for his 6-foot, 200-pound chassis.
* ''WesternAnimation/{{Ben 10}}'' did this a couple times, though
this. Somewhat surprisingly, it's {{Justified|Trope}} by the fact that, both times, Ben was transformed into an alien form that was five inches tall and gave him greatly enhanced brainpower.
* In a ''WesternAnimation/{{Jem}}'' episode, Jem, Aja, and Shana do this to escape a locked room.
* ''WesternAnimation/SpiderManTheAnimatedSeries'' constantly had Spidey doing this. During the Venom arc, after Peter finds the symbiote and experiences drastic changes to his personality, he considers but chafes at using the trope, saying "That's the old Spidey talking." He instead goes for the direct approach: kicking the steel door down and barging into Kingpin's meeting.
* Peter and Brian do this in an episode of ''WesternAnimation/FamilyGuy'', complete with a ShoutOut to ''Film/DieHard''. They don't make it all the way in stealthily, though, Peter's large girth causes the vent to give out and dump them right in the middle of the prom.
* ''WesternAnimation/{{Futurama}}''
** Subverted: Fry and Bender try to escape from a brig through a steam pipe vent. Unfortunately, the steam pipe is full of steam. At least they got a good sauna out of it.
** {{Lampshade|Hanging}}d in ''[[TheMovie Bender's Big Score]]''. While trying to destroy a [[Franchise/StarWars "Death Star"]], Al Gore's head in a jar flies a through an air vent actually ''labeled'' "Achilles' Vent", lasers a-blasting, successfully destroying it.
** In ''[[TheMovie Bender's Game]]'', Fry and the other travel around [[BigBad Mom's]] factory through a tube that sends chickens to the enslaved Nibblonians. It works, but they have to shove their way through a lot of chickens.
* {{Lampshade|Hanging}}d and subverted in an episode of ''WesternAnimation/BuzzLightyearOfStarCommand'', when Emperor Zurg chews out the designer of his latest evil lair for making the air ducts big enough for heroes to fit through.

** In one of Homer's daydreams where terrorists take over the plant, Homer jumps from a standing position into a vent on the ceiling, then comes out in Burns' office to beat the terrorists up.
** In "Lard of the Dance", Bart and Homer crawl through the vents while trying to steal grease from the school cafeteria, followed by an angry Groundskeeper Willie. The passageway is wide enough that Homer and Willie can fight inside of it.

* In ''WesternAnimation/SonicSatAM'', most episodes that contain Robotropolis have the main characters in an air duct at LEAST once. Robotropolis is perhaps Air Duct Central, essentially one giant factory bathing in its own heated (polluted) air. Lots of cool (polluted) air has to be moved around to keep the place from overheating somehow. By the way, Robotnik hates this trope:
-->'''Robotnik:''' [[TranquilFury Tell me, Snively, how did the hedgehog get past all my security]]?
-->'''Snively:''' Through an air duct, Dr. Robotnik.
-->'''Robotnik:''' An ''air duct?'' Then SEAL IT OFF!!



* Given her size, Jade from ''WesternAnimation/JackieChanAdventures'' utilizes these at times to get around places when no one else can. The episode "The Day of the Dragon" feature both her and the Dark Hand using the air vents to escape Section 13.
* {{Defied|Trope}} in ''WesternAnimation/WolverineAndTheXMen'': Wolverine and Gambit are trying to break into a secret lab to steal back a power inhibitor collar, and Wolverine suggests taking advantage of this trope. Gambit counters with: "Heh, only in the world of cinema. [[ThisIsReality In real life, they never hold]]." It certainly doesn't help that Wolverine's metal skeleton makes him about three times as heavy as a normal person.
* ''WesternAnimation/XMenEvolution''
** Subverted, with the vent being only a few inches long, big enough for people to climb into, having a ladder inside, and Blob gets stuck. However, it also has a large amount of security lids which Cyke was able to close to keep Mystique from escaping.
** Played with in another episode. When the group is testing out the security of the mansion, Wolverine is able to go to many parts of the mansion through the vents, and suggests something be done about them.

* In an episode of ''WesternAnimation/MaxSteel'', the only entrance to a highly-secured building is through the air vents. The only way in is by careful timing to avoid being sliced by a giant fan; the vents end two-thirds of the way up the wall in a room where the floor is littered with explosive devices, and not only do the air vents have cameras, they're also equipped with flamethrowers the big bad of the episode can activate at will.

Anakin argues that they're too small to gain access, but in response Ahsoka points out, that they might be too small for Anakin, Obi-Wan and the clones, but she might be able to squeeze through -- which she is, although barely. In the next episode Obi-Wan's entire team tries to escape the Citadel in absurdly spacious airvents. However these had lethally effective security doors, and the warden at least had enough common sense to send at least one drone in the airvents.

* An earlier Sam and Max, and Sam's granny Ruth, try to reach the prison warden this way in the ''WesternAnimation/SamAndMaxFreelancePolice'' episode "Christmas, Bloody Christmas" -- only, instead of ''WesternAnimation/EdEddAndEddy'' the air vent, they go through the prison's ''water duct'', and end up in the shower room.
* ''WesternAnimation/TheSimpsons''
** Parodied in the 100th episode. Santa's Little Helper gets into the school ventilation shafts, and only a greased Scotsman can catch him....
-->'''Groundskeeper Willie:''' "Lunchlady Doris...'ave ye got any grease?"
-->'''Lunchlady Doris:''' "Yes. Yes we do."
-->'''Groundskeeper Willie:''' (tears off his clothes) "Then grease me up, woman!"
-->'''Lunchlady Doris:''' ... "Okee-dokee."
-->'''Groundskeeper Willie:''' "There's nary an animal that can outrun a GREASED SCOTSMAN!"
** This is how Homer spies on Mr. Burns meeting with terrorists, and would be caught if it wasn't PlayedForLaughs:
-->'''Homer:''' ''(scribbling on pad)'' I love spying.
-->''(terrorist picks up a bar of uranium; radioactive gas boils off the surface of the rod)''
-->'''Burns:''' "Don't worry
about those fumes. They'll be sucked into that air vent."
-->''(Homer moans from fumes, drops pad out of vent and onto
the trio floor)''
-->'''Burns:''' "This place is falling apart." ''(walks over, picks up pad and shoves it back into the vent)''
** In one of Homer's daydreams where terrorists take over the plant, Homer jumps from a standing position into a vent on the ceiling, then comes out in Burns' office to beat the terrorists up.
** In "Lard of the Dance", Bart and Homer crawl through the vents while
trying to watch a monster movie marathon had them use steal grease from the school cafeteria, followed by an angry Groundskeeper Willie. The passageway is wide enough that Homer and Willie can fight inside of it.
* In ''WesternAnimation/SonicSatAM'', most episodes that contain Robotropolis have the main characters in an air duct at LEAST once. Robotropolis is perhaps Air Duct Central, essentially one giant factory bathing in its own heated (polluted) air. Lots of cool (polluted) air has to be moved around to keep the place from overheating somehow. By the way, Robotnik hates
this trope:
-->'''Robotnik:''' [[TranquilFury Tell me, Snively, how did the hedgehog get past all my security]]?
-->'''Snively:''' Through an air duct, Dr. Robotnik.
-->'''Robotnik:''' An ''air duct?'' Then SEAL IT OFF!!
* ''WesternAnimation/SpaceGhost'' episode "The Space Piranhas". Jan and Jace infiltrate an enemy base using the ventilation system. {{Lampshade|Hanging}}d when the BigBad says "As usual, the intruders have taken refuge in the ventilating system".
* ''WesternAnimation/SpiderManTheAnimatedSeries'' constantly had Spidey doing this. During the Venom arc, after Peter finds the symbiote and experiences drastic changes to his personality, he considers but chafes at using the trope, saying "That's the old Spidey talking." He instead goes for the direct approach: kicking the steel door down and barging into Kingpin's meeting.
* ''WesternAnimation/SpongeBobSquarePants'', "Truth or Square": after getting [[LockedInAFreezer locked inside the Krusty Krab freezer]], the gang makes their way out through the restaurant's labyrinthian ventilation system.
* ''WesternAnimation/StarWarsTheCloneWars''
** Ahsoka once escaped Griveous this way.
** Ventress used the airvents to infiltrate and sabotage a Republic Star Destroyer unnoticed.
** Cad Bane infiltrated the Jedi Temple through the airvents. Doubles as AbsurdlySpaciousSewer.
** Ahsoka Tano and Barriss Offee escape from mind-controlled Clone Troopers by jumping into the air vents. Later in the episode, Ahsoka uses the same vents to travel to the coolant control room and the bridge while she's running from Barriss.
** Aura Sing used these to attempt the assassination of Padmé.
** Subverted and lampshaded in "The Citadel". With the entry point the Jedi wanted to use blocked, Anakin and Obi-Wan muse how
to get in, and Ahsoka points on the ventilation hatch. Anakin argues that they're too small to gain access, but in response Ahsoka points out, that they might be too small for Anakin, Obi-Wan and the clones, but she might be able to squeeze through -- which she is, although barely. In the next episode Obi-Wan's entire team tries to escape the Citadel in absurdly spacious airvents. However these had lethally effective security doors, and the warden at least had enough common sense to send at least one drone in the airvents.
** In "A Test of Strength" Hondo Ohnaka proves he is smart by immediately recognizing the trick and having smoke bombs dropped into the vents to flush
out the occupants.
* ''WesternAnimation/TeenTitans'':
** Exception; Titans Tower's quarantine lock-down system apparently ''does'' seal off openings to the air ducts, as seen in the episode "Haunted". (Robin got into the vents anyway....)
** Subverted in the same series: Cyborg is attempting an Air Vent Infiltration in the episode "Wavelength" when the walls roll up and the thing rotates, dumping him into an arena and a battle with Bumblebee which he very nearly loses. He should've thought twice about even coming across a vent ''big enough'' for his 6-foot, 200-pound chassis.
* This is a favorite route
of the bathroom and girls in ''WesternAnimation/TotallySpies'' for breaking in, clearly thanks to MaleGaze.
** Also done in the spinoff ''WesternAnimation/TheAmazingSpiez'' though vaguely more realistically due
to the TV around Rolf(who was talking their ears off characters being 13 (Lee), 12 (Marc and Megan) and 11 (Tony). Even more plausibly the character seen doing this the most is Tony who, due to his young age, would realistically fit.
* ''Franchise/{{Transformers}}''
** ''WesternAnimation/TheTransformers'' episode "The Ultimate Doom, Part 2" introduced ventilation ducts large enough for Transformers to stand inside. Spike, Bumblebee & Brawn go through a ventilation shaft that takes them to Decepticon HQ. They're on Cybertron, where everything is of the same scale as Transformers are to humans, but why would they need air anyway?
** And pulled again in ''WesternAnimation/TransformersAnimated'', episode "Decepticon Air". Optimus Prime crawls through the ducts (it seems to be a squeeze, letting him homage ''Film/DieHard'' as well) of a spaceship -- maybe the air circulates to keep the energon from heating up and getting unstable? He does use it as a makeshift bomb, after all.
** ''WesternAnimation/BeastWars'': Cheetor goes through the ventilation shafts of the Predacon ship after having been accidentally transported to ''The Darksyde'' in "Equal Measures".
* The strangely clean air ducts of the SHIELD Helicarrier are lampshaded in the ''WesternAnimation/UltimateSpiderMan'' episode "For Your Eye Only" which, as a spy movie parody
with nods to ''Film/DieHard'', has Spidey using air ducts rather frequently.
* {{Defied|Trope}} in ''WesternAnimation/WolverineAndTheXMen'': Wolverine and Gambit are trying to break into a secret lab to steal back a power inhibitor collar, and Wolverine suggests taking advantage of this trope. Gambit counters with: "Heh, only in the world of cinema. [[ThisIsReality In real life, they never hold]]." It certainly doesn't help that Wolverine's metal skeleton makes him about three times as heavy as a normal person.
* ''WesternAnimation/XMenEvolution''
** Subverted, with the vent being only a few inches long, big enough for people to climb into, having a ladder inside, and Blob gets stuck. However, it also has a large amount of security lids which Cyke was able to close to keep Mystique from escaping.
** Played with in
another outlandish story). They do briefly get stuck, but Ed episode. When the group is testing out the security of the mansion, Wolverine is able to push them out go to many parts of the mansion through the vents, and suggests something be done about them.
* ''WesternAnimation/YoungJustice'':
** In "Homefront" - the DieHardOnAnX episode - Robin and Artemis spend a lot of time trying to avoid the Reds by crawling through the ducts;
with relative ease.varying degrees of success.
** In Season 2, a group of female team members do this in a bad guy's lair. The only one it makes sense for is Bumblebee who uses her shrinking powers to fit. On a more realistic note, all of the full-size heroines are shown having some difficulty maneuvering in the tight space.

Added DiffLines:

* Used in the Hulu series ''Freakish'' to navigate the school and get into a chemistry lab without running afoul of the "freaks" (basically zombies). Justified in that the people crawling through the vent are Zoe and Amber, the smallest members of the cast, and the vents in question lead to a chemistry lab, which would need somewhat larger vents than the rest of the school.

Thereafter, the Nazi research team does not live long enough to learn that EvilIsNotAToy.

* Played straight in a book based on the DonkeyKongCountry series, Donkey Kong was trying to get to a room containing a auto defense system in a building being built by Kremlings. As he tries to think of a way to get to the 8th floor without being seen, he hears guards coming, and goes into a nearby ventalation shaft. It's big enough to crawl through, and even has signs pointing him in the right direction.

* This happens a lot in ''VideoGame/BatmanArkhamAsylum''. Whenever opening doors, stealth or jumps are impossible, a conveniently placed vent will always be there to be busted open to save the day, and help you proceed. Sort of justified by the fact that Arkham Asylum is famous for having horrible security. Also, many of the buildings in Arkham are very old (The asylum as a whole dates back to the mid 19th Century), so the vents are likely from an old ventilation system.
** Every building in later Arkham games got their air vents from the same contractor, especially when there's a Predator mission in the building.
