There's all sorts of ways to see someone or something with {{Invisibility}}.

* Getting something (such as paint) all over the invisible target
* Get liquid over the invisible target, which will short the invisibility off
* Looking for footprints/tracks or shadows
* InfraredXrayCamera or other AppliedPhlebotinum
* SuperSenses or PsychicPowers
* Affecting the target's invisibility
* Having TrueSight

SeeThruSpecs is a SubTrope. Compare InvisibilityFlicker, for when the invisible entity makes itself visible through some flaw with their invisibility, and VisibleInvisibility, where the invisible character is visible to the audience. Contrast AntiTrueSight.



[[folder:Anime and Manga]]
* In ''DragonBall'', Yamcha defeated the Invisible Man after the Turtle Hermit (aka Master Roshi) had a nosebleed that spilled all over the Invisible Man.
* ''Anime/GhostInTheShellStandAloneComplex'': it's well-established that thermoptic camouflage is foiled by water. So how does the Major deal with the cloaked Umibozu troops? [[spoiler: She turns on the fire sprinklers.]]
* In ''KeroroGunsou'', the Keronians' anti-barrier makes them invisible to humans, but they also have control over who can see them. In rare cases, a person is able to see them regardless.
* In ''{{Gantz}}'', the hunters get controllers with the ability to turn their user invisible by "changing their frequency". Those who are also invisible and thus on the same frequency and see each other. [[OurVampiresAreDifferent The vampires]] carry with themselves special glasses and contacts with which they can see through the camouflage. Also some of the aliens, for example [[VoluntaryShapeshifting the Nurarihyon]], can see the invisible without any sort of equipment at all.
* This part of Nanami's TrueSight package in ''Anime/ElHazardTheMagnificentWorld''.
* In ''Anime/GundamBuildFighters'', Sei equips the Build Strike's head vulcans with "paintball" rounds, which Reiji uses to mark the Qubeley Papillon's clear plastic {{Attack Drone}}s.

[[folder:Films -- Animated]]
* In ''WesternAnimation/TheIncredibles'', one {{mook|s}} finds an invisible [[{{Invisibility}} Violet]] by throwing dust and watching for the cloud to be disrupted by a body.

[[folder:Films -- Live-Action]]
* In the ''Film/{{Predator}}'' movies, the title creature's invisibility device shorted out when immersed in water.
* Skinner from the film version of ''Film/TheLeagueOfExtraordinaryGentlemen'' wears white makeup so people can see his face. He also wears clothes, of course.
** Another invisible man ([[spoiler:Sanderson Reed]], actually) becomes partially visible when covered in dust. Also, Skinner later gets burned with a [[FireBreathingWeapon flamethrower]], showing charred skin.
* The invisibility process in ''Film/HollowMan'' doesn't stop the subjects from showing up on thermal cameras. The villain is also accidentally revealed just prior to an attack by the smoke from his victim's cigarette. In the climax, the heroes throw around paint to try and make him visible, or at least make sure his footprints show up.
* [[InvertedTrope Inverted]] in ''Film/StarTrekGenerations'': They can plainly see the Klingon Bird of Prey, but they are too badly damaged to muster enough firepower to penetrate the enemy's DeflectorShields. So they exploit a design flaw in the Klingon ship and ''force it to cloak''. Remember that in ''Franchise/StarTrek'', cloaked ships are unable to use sheilds or weapons. As soon as the Bird of Prey starts cloaking, ''Enterprise'' hammers the crap out of it.
* In ''Film/ForbiddenPlanet'', the invisible monster's tracks appear as it walks towards the spaceship, and its shape is later [[VisualEffectsOfAwesome rendered distinguishable by light-sparks]] when it returns and is caught in an energy fence.

* FairyTales and other magical lore indicate that a seeing stone also allows one to see things that have magicked themselves invisible.
* In the ''Literature/HarryPotter'' series, we've been shown several ways in which {{Invisibility Cloak}}s can be thwarted. The ability of dementors to sense people is not impaired by invisibility cloaks. Moody's magical eye can see through invisibility cloaks. A person wearing an invisibility cloak still shows up on the Marauder's Map. Mrs. Norris may or may not be able to see through invisibility cloaks. There are also some mundane constraints, such as the fact that the wearer remains solid, remains capable of making noise, etc.
* The wizards' Sight in ''Literature/TheDresdenFiles'' series can, among other things, pierce any kinds of veils and invisibility tricks. The downside of it is that not only does it show you that something is there, it shows you its ''true'' form, which is the last thing you want to see with the most [[EldritchAbomination supernatural heavy-hitters]]. Plus, there is a small fact that you can never ever forget anything you've seen with your Sight.
** There's also the caveat that some things will not look like what you expected, and even worse, some things will literally blind you with pain. In ''Turn Coat'', Harry uses the Sight to see who or what is following him early on, and subsequently crashes his car after blacking out for a minute. He then thinks about what he saw and blacks out again. After trying to walk away from his car, he accidentally thinks about it a third time, and wakes up in a gibbering, barely-sane mess on the sidewalk. By the time of ''Cold Days'', he's ''not'' immune to the mind-pain, but has managed to bring it down to a skip in his speech.
* In the [[Literature/DoctorWhoNovelisations novelisation]] of the ''Series/DoctorWho'' serial "The Daleks' Master Plan", the Doctor and his companions, on a planet inhabited by invisible monsters, throw one into a swamp to render it visible. The scene isn't present in the original serial.
* In ''TheStormlightArchive'' Rock can see spren all the time, while many of them can be invisible. He considers it disrespectful to point them out when they're trying not be seen though.

[[folder:Live-Action TV]]
* In 1983's ''[[{{Invisibility}} Invisible Woman]]'' PilotMovie, during the climax, Alexa Hamilton got covered in mud, making her visible.
* In an episode of ''Series/StargateSG1'', the humans were fighting an invisible enemy called the Reetou, but are given devices from the Tok'ra (Transphase Eradication Rods, or [=TERs=]) that can render them visible.
** These rods show up again when Nirrti develops a personal cloaking device based on natural Reetou ability. They also sweep the base several time throughout the series using [=TERs=].
* In the Sci-Fi Channel ''Series/TheInvisibleMan'' series, Darien shows up on thermals not because he's hot but because he's cold, as [[AppliedPhlebotinum quicksilver]] blocks visible light.
* In ''Series/LostGirl'', Bo could see auras, or at least sexual auras, and as such saw an invisible man when he was near the women he loved.
* In "Je Souhaite" of ''Series/TheXFiles'': Scully taps a body of a dead guy who was turned invisible by a LiteralGenie with a yellow powder and his whole body emerges. Scully is amazed and very, very excited by this positive proof of the paranormal.
* In the ''Series/{{Smallville}}'' episode "Shimmer", Clark Kent is able to see an invisible man because his skeleton still shows up on his XRayVision. In the episode "Fade", Clark tries this trick with another invisible man, but it doesn't work. He still manages to find him with his super hearing.
* ''Franchise/StarTrek'' contributes various forms of AppliedPhlebotinum to detect cloaked starships, including tachyon detection grids, metaphasic sweeps, antiproton beams, and quantum beacons.

[[folder:Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons'' has several examples.
** Early articles advised spreading dust/flour on the floor (to see footprints) or throwing flour/dust/water in the air (so it coats the opponent and reveals an outline).
** Certain spells can be used this way, such as True Seeing and True Sight.
** Dust of Appearance makes anything invisible it's sprinkled on become visible for everyone. Reveal Invisible (Al-Quadim) and Invisibility Purge (D&D3) spells do the same. Glitterdust doesn't remove invisibility as such, but anything corporeal dusted with sparkles becomes very noticeable.
* ''Star Fleet Battles'': It's possible to see cloaked Romulan ships with the "flash cube" effect (detonating a transporter bomb or mine).
* ''TabletopGame/CallOfCthulhu''
** Supplement ''Shadows of Yog-Sothoth'', adventure "Devil's Canyon": A race of invisible monsters can be seen if looked at through camera lenses prepared using CthulhuMythos knowledge.
** When the Powder of Ibn Ghazi is sprinkled on invisible monsters, it makes them visible.
* There's quite a few sources of invisibility in ''TabletopGame/{{Warhammer40000}}'' - from magic to chameleonic aliens to hyper-advanced powered armor - as well as ways to get around them. In game terms, as long as you can draw an unobstructed line from attacker to defender you can still declare the attack, you just suffer an accuracy penalty (Invisibility spell, Deathleaper's special camouflage) or the target gets a "cover save" (anything else). Flamethrowers ignore the "cover save" variant, and the Tau faction's laser-guidance "Markerlight" system can be used to light up less-than-visible foes.
** In the novel ''Fire Caste'', the Tau's advanced invisible "Stealth Suits" are rendered as the distortion effect to bionic eyes.

* ''{{BIONICLE}}'': in the ''Mata Nui Online Game'', a [[MegaNeko Muaka]] manages to snatch Kopaka, who was using the mask of invisibility, in its jaws after determining where Kopaka was by looking at his footprints in the snow.
** The Kanohi Rode, worn by Axonn, allows its user to see through any form of deception, including the aforementioned mask of invisibility.

* In ''EternalDarkness'', there's a level where you must (well, if you want some goodies, including a {{BFG}}, anyway) protect the player character's servants from an invisible monster. You can make this a lot easier by using the "reveal invisible" spell.
* In ''VideoGame/NetHack'', the grammatically suspect Ring of See Invisible and Potion of See Invisible grant this ability. You can acquire this power permanently by eating the flesh of a Stalker while already invisible.
* The Lens of Truth in ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' and ''VideoGame/TheLegendOfZeldaMajorasMask'' allows Link to see invisible things, as well as see through illusionary things like fake walls or floors.
* Tohno Shiki's power in ''{{Tsukihime}}'' prior to his near-death experience was "to see things which are hidden" - within the story it lets him see the normally invisible projections of a magical attack. After his near-death experience he can also see where ''death'' is hidden in every object and person, giving him OneHitKill powers but also [[BlessedWithSuck threatening his sanity]] with the result that he must [[PowerLimiter block his power]] with special glasses.
* ''VideoGame/TeamFortress2'': bumping into a cloaked spy reveals his outline. Fire is effective in revealing cloaked Spies, hence the importance of a Pyro's spychecking. Jarate and Mad Milk can be used to short out a Spy's cloak and reveal him to yourself and allies. Weapons that inflict bleed can be used to track cloaked spies if it hits.
* ''StarCraft'': the Zerg Queen's Ensnare ability shoots a big gob of mucus in an area, slowing down everything caught in it. As a happy side effect, it also reveals invisible units (or rather the person-shaped glob of zerg snot just standing there). The defiler's Plague and several other abilities have a similar effect. In ''StarCraftII'' abilities such as the infestor's Fungal Scourge mimic this effect.
* ''VideoGame/TheElderScrollsVSkyrim'' has the shout 'Aura whisper' which reveals all enemies, living, undead, daedra and mechanical, even if they are hiding in the landscape (coffins, holes, pile of bones/ash) or invisible. Detect dead can also be used to find fleeing invisible vampires.
* In ''VideoGame/GodOfWarII'', you can tell where Perseus is because he's in a shallow pool of water.
* In the ''VideoGame/Homeworld'' games there's a number of ships capable of cloaking themselves (and, in the case of the un-armed cloak generator, a small number of other ships). To counter them, you can either build advanced sensor platforms (or just upgrade your mothership with these) capable of showing them, or wait for them to become visible when opening fire.

[[folder:Western Animation]]
* ''JonnyQuest'' once had this invisible monster which was created by some AppliedPhlebotinum and went on a rampage. Jonny and Hadji dumped a bunch of paint over it, which not only made it visible, but also made it look much less terrifying.
* In the ''WesternAnimation/TomAndJerry'' short "The Invisible Mouse", Tom tries to find an invisible Jerry by throwing flour on the floor so that Jerry would leave footprints. When he does, Tom tries to hit him with a [[FryingPanOfDoom frying pan]]. Moments later, the words "Missed me" appear on the flour.
* In ''TheTrapDoor'', one of the recurring monsters, Bubo, is invisible, until Berk manages to hit it with a glob of some yellow stuff. It has remained yellow ever since.
* One episode of ''KaputAndZosky'' featured the duo landing on a planet where everyone is invisible. They make the aliens visible by catching them in a butterfly net and spray painting them red.
* WileECoyote once used a mail-order chemistry set to become invisible to try and catch the Road Runner...unfortunately, although his prey couldn't see him, neither could the driver of an oncoming truck. After he was struck, his footprints in the sand became noticeably staggered, and he fell off a cliff, [[ImpactSilhouette making Coyote-shaped holes in several clouds on the way down]].
* In one episode of ''WesternAnimation/BatmanTheAnimatedSeries'', Batman is fighting a man wearing a suit that makes him invisible, and the Invisible Man is winning. Up until Bats breaks a nearby watertower, and raining spray reveals the man's form.
-->'''Batman:''' Peekaboo. ''(POW!)''
* An episode of ''JackieChanAdventures'' had Jade quickly responding to fighting an invisible enemy by attempting to get paint on his clothes. But then, she's [[ActionSurvivor used to dealing with magic weirdness.]]
