History AirVentPassageway / Webcomics

* ''Webcomic/{{Banished}}'': To escape from the Boscis base, Rak and Timbo follow a Mammazon out this way.

* [[http://freefall.purrsia.com/ff800/fv00770.htm Subverted]] in ''Webcomic/{{Freefall}}'', when Sam finds out the hard way that the air ducts on his ship are not ''quite'' big enough for him to hide in. He might have succeeded if he had ditched [[StarfishAliens his encounter suit.]]

* ''Webcomic/QuestionableContent'': Subverted when Raven attempts to enter Coffee of Doom through the airvent and gets stuck. She's not the [[TheDitz sharpest of minds]]. The reason she tried in the first place is because she and another character, both recently hired there, show up to their opening shift and realize that neither of them have a key, on a day their boss is taking some personal time. Cue Raven's [[SarcasmMode exceedingly well-crafted plan]] to get in so they could open the shop without bothering said boss.

* ''Webcomic/{{TREVOR}}'': How [[spoiler: Trevor escapes]] the autopsy room and ambushes the medical team.

* In ''Webcomic/{{Outsider}}'', Jardin {{lampshade|Hanging}}s [[http://well-of-souls.com/outsider/outsider031.html the lack of handy vents.]]
* [[http://permanentinc.thecomicseries.com/comics/11 Malum Industries]] of ''Webcomic/PermanentInc'' have air ducts built [[InvokedTrope intentionally wide enough to crawl through]].
* Subverted in ''Webcomic/QuestionableContent'' when Raven attempts to enter Coffee of Doom through the airvent and gets stuck. She's not the [[TheDitz sharpest of minds]], though.
** And it's not like she was trying to rob the place or anything. She and another character, both recently hired there, show up to their opening shift and realize that neither of them have a key, on a day their boss is taking some personal time. Cue Raven's [[SarcasmMode exceedingly well-crafted plan]] to get in so they could open the shop without bothering said boss.

* Justified in ''Webcomic/SchlockMercenary'', as Schlock is a carbosilicate amorph -- he can squeeze through air vents no matter ''how'' small they are -- well, except for his eyes (standard SphereEyes) and his plasgun ([[HandCannon big]]).
-->"Did you check the air vents?"\\

* In ''Webcomic/TheInexplicableAdventuresOfBob'', this is how a quartet of [[http://bobadventures.comicgenesis.com/d/20120327.html time-displaced ninjas]] escape from the museum where they have awoken.

* ''Webcomic/Angels2200'': Loser uses one when they attempt to "rescue" Quetz
* [[http://freefall.purrsia.com/ff800/fv00770.htm Subverted]] in ''Webcomic/{{Freefall}}'', when Sam finds out the hard way that the air ducts on his ship are not ''quite'' big enough for him to hide in. He might have succeeded if he had ditched [[StarfishAliens his encounter suit.]]

"No one that has seen ''you'' in action [[NightmareFuel forgets to check the air vents]]."
** Spoofed when the mercenaries are pretending to enter via the sewers and air vents when entering an underground bunker to hide the fact that they actually [[DestructiveTeleportation teraported]] inside. One panel shows them making their way along the ledge of a giant air vent. Then the guards are shown complaining about the smell of sewerage that's being carried around the bunker.
* Justified in ''Webcomic/GunnerkriggCourt'', as the Enigmaron fortress that Antimony infiltrates is a [[HardLight simulation]].
* Used in a ''[[http://ubersoft.net/comic/hd/2007/11/secret-weapon Help Desk]]'' comic, the reasoning behind such large vents is questioned and explained as ContractualGenreBlindness in [[http://ubersoft.net/comic/hd/2007/11/bureaucracy-evil the next strip]].

* ''Webcomic/{{Banished}}'': To escape from the Boscis base, Rak and Timbo follow a Mammazon out this way.
* ''Webcomic/CharbyTheVampirate'': When Tony was cornered near a door he couldn't use inside the hunters' headquarters (since as an alp he can only leave the building the same way he entered it) he took possession of a rat monster to take the vents to where he needed to go.
* Justified in ''Webcomic/{{Curvy}}'' when used by a native of [[PlanetOfHats Candy World]] who is actually a ''liquorice''-based organism: she can squeeze into places a normal human wouldn't be able to. In fact, in the immediately previous page she's seen squeezing through the bars of a prison cell.
* Averted in ''Webcomic/DeadWinter''. Lou's plan for getting into the store for supplies involves this method, but Monday objects on the grounds that he won't fit. Apparently he's tried before.
* In ''Webcomic/{{Drowtales}}'', the air vents are too small for an adult Drow. But for a child...
* Trigger from ''Webcomic/FarOutThere'' is [[http://faroutthere.smackjeeves.com/comics/1067778/page-151-hey-at-least-its-not-all-going-to-waste/ very good at these]].
* In ''Webcomic/GirlGenius'' Castle Wulfenbach has a number of truly enormous grated vents which Gil uses to take Tarvek, Bang and Vole to one of his hidden labs when Tarvek figures out Gil's father has [[spoiler:been wasped]] and is somewhere on the ship covertly giving orders. Gil notes that Tarvek really needs to escape since even if he's wrong about what has happened to the Baron the Baron would likely have him shot on sight.
* In ''Webcomic/ElGoonishShive'', Noah uses air vents in the process of hunting a magical creature, and the trope is discussed in the commentary. And Noah also does it to ''get around school''! Raven has to shout at him to use the door.
* In ''Webcomic/TheMotleyTwo'', the spaceship "Hiroja" has vents big enough that the characters can sneak around the entire ship with impunity. Perria Makara, who snuck aboard undetected, even sleeps quite comfortably in the vents (near the heating unit).
* ''Webcomic/MetroidThirdDerivative'': Samus with the Morph Ball up until [[TheCorruption Phazon corruption]] damaged her Varia Suit and required emergency repairs destroying the Morph Ball in the process.
* ''Webcomic/NerfNow'' on [[http://www.nerfnow.com/comic/735 air ducts in games vs. reality]]. No inescapable death trap is complete without one!
* {{Lampshade|Hanging}}d by the DeadpanSnarker in the improvisational comic ''The Omega Key'' on [[http://www.drunkduck.com/The_Omega_Key/index.php?p=229585 this page]], where he finds it suspiciously convenient that he (a ''6'10"'' man) can fit in an air duct. (He was right, as the destination turned out to be a trap.)
* In ''Webcomic/{{Outsider}}'', Jardin {{lampshade|Hanging}}s [[http://well-of-souls.com/outsider/outsider031.html the lack of handy vents.]]
* [[http://permanentinc.thecomicseries.com/comics/11 Malum Industries]] of ''Webcomic/PermanentInc'' have air ducts built [[InvokedTrope intentionally wide enough to crawl through]].

* ''Webcomic/LearningWithMangaFGO'': Gudao sneaks through Chaldea via the air vents, but they are so narrow that he has to strip to his underwear and cover himself with cooking oil to get through them. After he steals from Anastasia, she forces Kadoc to chase him through the air vents. Kadoc is reluctant and says they should come up with a better plan, but she makes him strip, cover himself with oil, and enter the vents.

* ''[[Webcomic/MetroidThirdDerivative Metroid: Third Derivative]]'': Samus with the Morph Ball up until [[TheCorruption Phazon corruption]] damaged her Varia Suit and required emergency repairs destroying the Morph Ball in the process.
