* The 2012 ''VideoGame/NeedForSpeedMostWanted'' has cinematics for each car on the Most Wanted list that you race and then take down. The Koeniggsegg Agera R's intro consists of a black spore that starts creeping tendrils, growing in size before suddenly twisting and contorting around until revealing the Swedish hypercar.

* ''VideoGame/TheLegendOfZeldaBreathOfTheWild'' and ''VideoGame/HyruleWarriorsAgeOfCalamity'' feature [[MadeOfEvil Malice]], a black tar-like substance that infects and consumes everything it touches. It spawns from [[BigBad Calamity Ganon]], an [[AnimalisticAbomination boar-like demon]] consumed by its hatred for Hyrule for the numerous defeats it had suffered over the eons. It's potent and sentient enough to possess robots and even create harbingers of evil known as Blight Ganons.

* Thick, foul-smelling black slime is secreted by hosts of the Ourobouros virus in
''VideoGame/ResidentEvil5''.

* ''TabletopGame/{{Pathfinder}}'' has the black blood, a freezing cold, pitch black liquid that seems from the walls and runs in rivers through a vast cavern in the deepest level of the Darklands. Not only is it cold enough to cause harm, it's unholy and mutagenic, causing creatures to become amphibious monstrosities with additional abilities even as it slowly kills all but the strongest hosts. Drinking it also provides a power boost to necromantic spells, assuming it doesn't kill you. Naturally the stuff is a prized commodity among liches, exiled fiends, derro, driders, and pretty much every nasty under the earth with either sanity or morals in short supply.

* One of the enemies in ''VideoGame/CastlevaniaSymphonyOfTheNight'' is the black panther, which appears only in the Anti-Chapel and appears almost identical to the one encountered in ''Castlevania Chronicles''. However, unlike the other black panthers that have appeared in the series so far, ''this'' one isn't a big cat at all, but a [[BlobMonster blob of oozing black fluid]] that has shapeshifted into the form of a panther. In combat with you, it will periodically revert to liquid form and slide out of range so it can attack again - and worse still, it's pretty much indestructible in liquid form.

* In ''TabletopGame/MagicTheGathering,'' Phyrexian Oil is a black substance that [[MutagenicGoo infects and corrupts anything it touches]], ultimately consuming the plane of Mirrodin and transforming it into New Phyrexia.

* ''Characters/{{Pibby}}'': The Static, a dark force consuming the multiverse, takes the form of a tide of black matter covered in colorful static glitches.

* The FinalBoss of the multiplayer campaign of ''VideoGame/MonsterHunter 4 Ultimate'', Gogmazios, attacks with a black, tar-like substance that incapacitates hunters and, if not gotten rid of quickly, will explode and cause them massive damage. Supposedly, the monster got all this substance in its body after a lifetime diet of sulphur and gunpowder.

An offshoot of DarkIsEvil, it's not uncommon for such substances to be associated with much more unpleasant effects than other {{Technicolor Toxin}}s from across fiction, including agonizing pain, mutations, mind control, a CruelAndUnusualDeath, or even a FateWorseThanDeath. In some depictions, this substance can even be ''alive,'' resulting in many a horrific BlobMonster.

* Hexxus, the primeval spirit of destruction in ''WesternAnimation/FernGullyTheLastRainforest'', initially emerges from his prison tree in the form of a tiny blob of dark brown slime, gradually expanding his mass by feeding on the Leveller's exhaust until he can metamorphose into a wraith made of black smoke. After losing control of the Leveller in the finale, he goes OneWingedAngel and assume his ultimate form: [[HumanoidAbomination a giant skeletal monstrosity]] made entirely of black ooze.

* In the ''WesternAnimation/WinxClub'' movie ''Secret Of The Lost Kingdom'', a black goo makes up the gate to a dimension in which the people of Domino are imprisoned. Said dimension is literally called Obsidian Circle.

* The plot of ''Film/District9'' first begins to heat up when Wikus finds the cylinder of MutagenicGoo that Christopher Johnson was saving up, and fiddling with it results him accidentally getting a spray of oily black gunk to the face. Before long, Wikus is puking up BadBlackBarf and transforming into one of the aliens...

* The Filth of ''VideoGame/TheSecretWorld''. This MysticalPlague can take on many forms across the setting, but the most common variant is a tarry black slime studded with writhing tentacles. Forming huge puddles, oily creepers and vast bubble-studded swamps of the stuff, one touch is enough to kick off infection, resulting in paranoia, delusions, violent insanity, hideous mutations, and subservience to the will of [[EldritchAbomination the Dreamers]] -- for the Filth itself is their ''dream'' of [[SealedEvilInACan escaping from captivity]] made manifest as a disease. Infectees are covered in an oily layer of Filth that only draws further attention to the tentacles and GlowingEyesOfDoom they sport, and later-stage infectees are ''made'' of it -- transcending humanity to become monstrous entities of pure Filth. Fortunately, the player characters are immune to the mutations and brain-warping effects, so it can only kill them -- [[ResurrectiveImmortality temporarily]]. Everyone else... not so much.

* ''VideoGame/EpicMickey'': The game's main antagonist, the Blot, is an enormous monster made from an oozing black mixture of paint and thinner. Its corrupting slime has dripped and spread all over Wasteland, creating smaller enemy blobs called Blotlings and causing all sorts of destruction.

[[folder:Web Comics]]
* As suggested by its name, the Black Touch in ''WebComic/{{Wurr}}'' appears to be a glistening, bubbling tar-like substance that occurs in pools within the Crater, and is an extremely dangerous MutagenicGoo capable of making the hounds that live there grow all sorts of interesting extra or misshapen body parts.

** In ''[[Recap/BigFinishDoctorWho133CityOfSpires City Of Spires]]'', a visit to 18th-century Scotland reveals that the place is littered with anachronistic pumpjacks owned by the Hirudin Corporation. The Doctor soon discovers that what they're extracting isn't oil, though it looks the part: called "Black Water," it's often seen [[BodyHorror being pumped into unwilling victims]] [[ReforgedIntoAMinion to create]] [[TheBrute Red Caps]], the corporation's SuperpoweredMooks.
** The next episode in line, "[[Recap/BigFinishDoctorWho134TheWreckOfTheTitan The Wreck Of The Titan]]," sends the Doctor and Jamie on a complicated voyage that somehow ends with them aboard Captain Nemo's ''Nautilus'', hunting giant squid for their ink. As it turns out, when refined, the ink is identical to the Black Water. Also, harvesting it is a good way of enraging even bigger squid...
** The conclusion of the trilogy, "[[Recap/BigFinishDoctorWho135LegendOfTheCybermen Legend Of The Cybermen]]" reveals the truth: [[spoiler: all three stories are set in the Land of Fiction, and the Black Water is actually ink, a precious resource used to recreate fictional characters killed in battle with the Cybermen. Though more beneficial than the last two instances, it's still played for tension when it turns out that fictional characters ''bleed'' ink - revealing that the Jamie who's been travelling with the Doctor for the past few episodes isn't real.]]

* In the ''Literature/WorldWarZ'' fanfic ''[[https://www.fanfiction.net/s/6115555/1/The-Way-Is-Shut The Way Is Shut]],'' a recon team investigates the ruins of North Korea in the wake of the ZombieApocalypse, eventually finding the entrance to the UndergroundCity the population retreated to. However, one of the doors is leaking a black ooze that "smelled of death," the result of rotten flesh decomposing to the point of liquefaction and mixing with floodwater. Either because the pumps have failed or because there's no-one left alive to operate them, a huge lake full of corpses has built up behind the doors - and at least some of them are zombies. And if that black slime is leaking out ''now,'' [[spoiler: it won't be long until the hastily-built shelter bursts open and releases all those millions of zombies back into the world.]]

* In the ''WesternAnimation/WinxClub'' movie ''Secret Of The Lost Kingdom,'' a black goo makes up the gate to a dimension in which the people of Domino are imprisoned. Said dimension is literally called Obsidian Circle.

[[folder: Film - Live-Action]]

* The Dark Queen of ''Film/MirrorMask'' has the power to [[CastingAShadow create]] strange liquid shadows by literally [[BadBlackBarf vomiting them into existence]]: first encountered oozing along walls and floors like oil, they can also sprout tentacles or even shape themselves into birds in order to ensnare their victims - which are fatally petrified unless the Queen's taken an interest. They can even be used as part of a OneWingedAngel transformation.

* ''Film/Venom2018'' sees the titular symbiote and its kin naturally take the form of sentient mobile slimes and though all have dark colourations, only Venom is pitch black - even then, the trope is {{Inverted|Trope}} over the course of the movie, [[spoiler: in that Venom, the black one, is the only one of their number to undergo a HeelFaceTurn into something that can [[NominalHero vaguely be described as heroic]]]].

[[folder: Literature]]
* ''[[Literature/DarkShores Dark Skies]]'': The blight. At first it is believed to be just a nuisance, a river of foul-smelling black goo flowing through the countryside. Later, however, it turns out that it also brings a MysticalPlague, which turns any living being that comes into contact with it into a zombie-like creature. Not to mention the fact that it can [[spoiler: undermine city walls]].
* In ''Literature/TheHungerGames: Literature/{{Mockingjay}}'' one of the many traps deployed against the rebels in the Capitol is a wave of a black tar-like that threatens to engulf anyone in its path - featured in horrific detail in the [[Film/TheHungerGamesMockingjay film adaptation.]]

* "[[Literature/Slime1953 Slime]]" by Creator/JosephPayneBrennan: The title creature is a black amorphous blob from the bottom of the sea.

[[folder: Live-Action TV]]
* In ''Series/{{Farscape}}'', Luxans have an unusual biological quirk that [[BizarreAlienBiology causes their blood to become dangerously toxic upon exposure to air]]; when this happens, the blood turns a shade of red so dark it appears ''black''. The only cure for this is for the wound to be repeatedly pummelled to stimulate the blood flow and cleanse the poison - whereupon the black blood turns transparent and runs clear until the wound heals.

* ''Series/StarTrekTheNextGeneration'': In "[[Recap/StarTrekTheNextGenerationS1E22SkinOfEvil Skin of Evil]]", an away team beaming down to a planet to rescue a crashed shuttle finds their path blocked by a pool of tar-like black liquid, which moves to bar their passage them when they try and maneuver around it. It turns out to be a living entity called Armus, who is literally MadeOfEvil: he's the cast-off imperfection of a race that [[AscendToAHigherPlaneOfExistence transcended]] a long time ago, and while he can take on a roughly humanoid form, he always retains his tarry complexion. [[spoiler: On top of screwing around with Riker, Geordi, Troi and Data, he also murders Tasha Yar.]]

* The Black Oil of ''Series/TheXFiles''; a sapient parasitic mind-controlling goo used by the alien colonists to reproduce and take over the universe, it can often be found invading potential hosts through their eyes, mouth, nose or ears. Ironically, the slime itself isn't the danger: "Purity" - as the aliens call it - is actually a virus that thrives in oil deposits deep underground, hence its oily appearance. However, that doesn't stop the show from playing its petroleum-like aspect for horror, with hosts sporting BlackEyesOfEvil and BadBlackBarf.

[[folder: Podcasts]]
* In ''Podcast/TheAdventureZoneBalance,'' [[spoiler: the Hunger, an evil sentient plane of existence, is described as tar-like with the coloring of black opal.]]

[[folder: Tabletop Games]]

* In the ''TabletopGame/TheEndOfTheWorld: ZombieApocalypse'' scenario "Under The Skin," the menace of the story is an ancient PuppeteerParasite unearthed by a mining operation. It takes the form of a tarry black fungal gunk infesting any living thing it touches, gradually reducing its victims to decomposing zombies. This is bad enough, but if allowed to clump together after their host bodies break down, the parasite can form a giant BlobMonster of Kaiju proportions. [[spoiler: The stuff is so dangerous that the governments of the world opt to move their people into underground bunkers and nuke the surface to a crisp rather than let the parasite roam free.]]

* The Ruin of ''VideoGame/AliceMadnessReturns'': a noxious black pollutant found splattered across Wonderland, it corrupts and ruins the environment, and it’s also capable of moulding itself into doll-headed monstrosities for Alice to do battle with. It’s actually runoff from the Infernal Train destroying Wonderland - and Alice’s mind.

* A recurring element in ''VideoGame/CallOfTheSea''. The island produces a mysterious black ooze that either drives people murderously insane or [[spoiler:morphs them into a FishPerson.]]

* [[PsychoExGirlfriend Sasha]] of ''VideoGame/{{Infamous}}'' has the power to exude a mind-controlling black tar from her body. By force-feeding it to the Reapers, she transformed them into loyal soldiers, and by [[WaterSourceTampering introducing it to the local water supply]], she hopes to recruit the civilians of the Neon District into her growing army. For added horror, the boss battle reveals that Sasha is ''milking'' her body to produce the tar in bulk - to the point that it's become part of her ensemble: close examination reveals that she's technically naked apart from the black gunk covering her lower body.

* The FesteringFungus in ''VideoGame/ResidentEvil7Biohazard'' covers many locations in thick sheets of black, oozing mould, and also creates [[MushroomMan Mushroom Men]] comprised of tangled ropes of fungal matter. Worse still, it's also capable of infesting people like the [[HillbillyHorrors Baker family]], enhancing their strength, driving them insane, and [[spoiler: rendering them subservient to [[BigBad Eveline]], who emits this stuff by nature.]]
* ''VideoGame/RogueStormers'' features the Goop, an oily black substance that horribly mutates living beings in addition to powering {{Dieselpunk}} tech. It's even drilled from the depths of the Earth like real oil.
* The Filth of ''VideoGame/TheSecretWorld''. This MysticalPlague can take on many forms across the setting, but the most common variant is a tarry black slime studded with writhing tentacles. Forming huge puddles, oily creepers and vast bubble-studded swamps of the stuff, one touch is enough to kick off infection, resulting in paranoia, delusions, violent insanity, hideous mutations, and subservience to the will of [[EldritchAbomination the Dreamers]] - for the Filth itself is their ''dream'' of [[SealedEvilInACan escaping from captivity]] made manifest as a disease. Infectees are covered in an oily layer of Filth that only draws further attention to the tentacles and GlowingEyesOfDoom they sport, and later-stage infectees are ''made'' of it - transcending humanity to become monstrous entities of pure Filth. Fortunately, the player characters are immune to the mutations and brain-warping effects, so it can only kill them - [[ResurrectiveImmortality temporarily]]. Everyone else... not so much.

* Structure Gel in ''VideoGame/{{SOMA}}'' is a black, slimy chemical that can serve both as an electrical conductor and as MutagenicGoo that forcibly melds flesh and metal together. By the time of the game, [[TheComputerIsYourFriend WAU]] has covered PATHOS-II with Structure Gel MeatMoss in its quest to assimilate the remnants of humanity into itself; as a result, you'll find the gel itself leaking from the ceiling at various points across the station. [[spoiler: Simon's half-corpse half-machine body is actually held together with it, and late in the game, he has to acquire more Structure Gel in order to build a new body capable of entering the [[EldritchOceanAbyss Abyss]].]]

* ''VisualNovel/FateStayNight'': The "black mud" of [[spoiler: Angra Mainyu, which resides in the Holy Grail]] contains "All the World's Evil" and is basically TheCorruption in (mostly) liquid form.

* ''WesternAnimation/BojackHorseman'': Features prominently in Bojack's dream in [[Recap/BojackHorsemanS6E15TheViewFromHalfwayDown "The View From Halfway Down"]], as a tar-like substance that drips from the ceiling. As the episode climaxes, the empty void beyond the door which people keep disappearing into reaches out as more of the black liquid and consumes the entire dream world, representing not only the darkness and despair of death and depression that seem inescapable to him, but also harkening back to a metaphor of the tarpits in LA symbolizing the toxicity he carries with him and its effect on himself and the people around him, [[spoiler: and (more literally) the water getting into his body as he's drowning himself]].

* ''WesternAnimation/RickAndMorty'': In "[[Recap/RickAndMortyS4E1EdgeOfTomortyRickDieRickpeat Edge of Tomorty]]", Morty's attempts at following the crystal's predictions come to a head when he steals some ferrofluid from Rick's lab and uses it on himself. Essentially an oily, black semi-liquid that continuously sprouts roots and tentacles, it envelops Morty in a monstrous techno-organic tree in which he's determined to wait until the crystal shows him the next step to dying in Jessica's arms. Thankfully, Rick, Wasp Rick and Hologram Rick are there to drag him out of it. [[spoiler: Unfortunately, it then fuses with Hologram Rick, giving him a physical body and transforming him into a giant. Proclaiming himself a god, he tries to kill the other three -- only to be brought down by Wasp Rick's parasitic larvae.]] Ferrofluid exists in RealLife, by the way, and needless to say, it does not do that.

* ''WesternAnimation/SamuraiJack'': Aku spends most of his time on Earth as a pool of pitch black goop resembling a tar pit, though later on a tree-like spire rises out of its middle. Any living thing that touches this goop is slowly pulled in with tremendous force, and their matter is converted into more of the goop, enlarging the pool.

* ''WesternAnimation/RickAndMorty'': In "[[Recap/RickAndMortyS4E1EdgeOfTomortyRickDieRickpeat Edge of Tomorty]]", Morty's attempts at following the crystal's predictions come to a head when he steals some ferrofluid from Rick's lab and uses it on himself.
