11	-->-- '''The Buzzing''', ''VideoGame/TheSecretWorld''
12
13	In fiction, not all harmful substances take the form of a [[SicklyGreenGlow sickly green]] poison that [[PoisonIsCorrosive eats through anything it touches]]: indeed, there's a growing tendency for harmful, deadly or just plain evil substances to be depicted as glistening black slime, often reminiscent of oil, tar, or ink.
14
15	An offshoot of DarkIsEvil, it's not uncommon for such substances to be associated with much more unpleasant effects than other {{Technicolor Toxin}}s. They may also cause agonizing pain, [[MutagenicGoo mutations]], mind control, a CruelAndUnusualDeath, or even a FateWorseThanDeath. In some depictions, this substance can even be ''alive,'' resulting in many a horrific BlobMonster.
16
17	It seems likely that these depictions of evil pitch-black liquids were inspired by the threat posed by oil spills or tar pits, both of which are well known for being serious hazards. They are also environmental blights that can turn a place into a PollutedWasteland. With this in mind, it may lend itself to depictions of the MuckMonster.
18
19	Also, consider HazardousWater and the PrimalFear it evokes. Water can be dark and inhospitable, it can engulf and drown you, and it may conceal nasty creatures. Ominous Obsidian Ooze shares these scary qualities and {{exaggerate\|dTrope}}s them.
20
21	Whatever the case, if an unidentified black liquid crops up in fiction, it'll probably mean something very, very bad.
22
23	May result in BadBlackBarf.

27
28	[[folder:Anime and Manga]]
29	* ''Manga/NoLongerAllowedInAnotherWorld'': Yuriko, the Fallen Angel of Avarice, possesses the gift "Cruel Avarice", manifesting as a vicious dark slime that does her bidding. It attacks, defends, generates portals, summons [[DemBones skeletons]] to do her bidding and can even induce RapidAging.
30	* Dark Paint from ''Anime/SmilePrettyCure'' is said to be the essence of the show's BigBad, Emperor Pierrot. The QuirkyMinibossSquad break open tubes of it and swipe it across blank books in order to "paint your bright future(s) black", referring to the VictimOfTheWeek, which sends them into near-hopeless despair.
31	[[/folder]]
32
33	[[folder:Audio Plays]]
34	* ''AudioPlay/BigFinishDoctorWho'':
35	** 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 [[ReforgedIntoAMinion being pumped into unwilling victims to create Red Caps]], the corporation's SuperpoweredMooks.
36	** 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...
37	** 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]].
38	[[/folder]]
39
40	[[folder:Comic Books]]
41	* The eponymous ''ComicBook/BlackGas'' starts out as just that, a volcanic cloud of black DeadlyGas, but when inhaled it causes a rapid series of neurological changes, suppressing its hosts' rationality and stripping away all civilized impulses. At the same time, the host constantly weeps black tears and drools BadBlackBarf -- if an uninfected person gets an infected's bodily fluids in their mouth, eyes, or an open wound, they'll slowly be overcome.
42	* ''ComicBook/{{Nnewts}}'' has Blakk Mudd, a black liquid that turns any Nnewt it touches [[ReforgedIntoAMinion into a Lizzark]].
43	* ''ComicBook/{{Venom}}'': In all of the Venom Symbiote's incarnations, it is a [[BlobMonster shapeshifting blob of black gunk]] that can bond with a host and give them superhuman powers ([[TheCorruption usually at great cost]]). As a species, the Symbiotes vary in color (ComicBook/{{Carnage}} is blood-red); however, ''ComicBook/VenomDonnyCates'' reveals that the symbiotes are comprised of "[[LivingShadow living abyss]]" and created by a primordial GodOfDarkness, bringing the species as a whole more in line with this trope.
44	[[/folder]]
45
46	[[folder:Fan Works]]
47	* The titular Corruption of ''VideoGame/FridayNightFunkinCorruption'' coats whatever it touches in a strange, black substance, including [[TheProtagonist Boyfriend]], who promptly becomes a [[BrainwashedAndCrazy brainwashed]] PlagueZombie and spreads it across the entire Friday Night Funkin' cast. [[spoiler:As of Week 8, the Corruption turns out to be ''[[ItCanThink sentient]]'', threatening him when he tries to resist it [[FightingFromTheInside from inside his own head]].]]
48	* In ''Fanfic/PokemonMysteryDungeonLostTracksOfTime'', [[spoiler:Giratina]] bleeds an "impossible black" substance that eats away at any matter it contacts -- [[TorsoWithAView including other Pokémon]]. [[spoiler:Ingo and Emmet also bleed a similar black substance, though it does not appear to have the same destructive capabilities as Giratina's.]]
49	* 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]].
50	[[/folder]]
51
52	[[folder:Film -- Animated]]
53	* 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 assumes his ultimate form: [[HumanoidAbomination a giant skeletal monstrosity]] made entirely of black ooze.
54	* In ''WesternAnimation/TheIncredibles1'', Mr. Incredible is subdued in Syndrome's SupervillainLair by dozens of unremovable "balloons" of black goo that expand and completely engulf him.
55	* In ''Anime/LittleNemoAdventuresInSlumberland'', the Nightmare King first takes the form of a living black liquid that sweeps through the castle and ensnares King Morpheus.
56	* ''WesternAnimation/TeenTitansTroubleInTokyo'': Brushogun used to be a normal artist until he turned to dark magic to make one of his creations alive. The price was his own transformation into an ink-filled, paper-skinned entity with the ability to create inky minions. Both Brushogun and the minions can look normal, but their true form is pure ink.
57	* 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.
58	[[/folder]]
59
60	[[folder:Film -- Live-Action]]
61	* In ''Film/BeyondTheBlackRainbow'', the Arboria Institute has developed an experimental hallucinogen in the form of a black liquid, which seems to induce psychedelic experiences, psychic powers, and mutations. [[spoiler:It definitely had an adverse effect on Dr. Nyle -- when he is [[SymbolicBaptism immersed in a pool of the black fluid]], he sees "the eye of God", loses his hair, gains BlackEyesOfEvil, and goes homicidally insane.]]
62	* ''Film/{{Clawed}}'': This appears to be the source of all the death in the movie. One con artist tried to make money off it by stating it has healing properties. Well, it is definitely '''[=NOT=]''' to be touched.
63	* ''Film/Creepshow2'': In "The Raft", a group of college kids on a raft in the middle of a lake are tormented and eaten by a [[BlobMonster large, black blob]] reminiscent of an oil slick floating on the surface of the water.
64	* 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 in 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...
65	* In ''Film/EvilDead2'', several people possessed by demons are seen [[BadBlackBarf drooling black ooze]]. At one point Ash is hit with a ''torrent'' of it after blowing a hole in the cabin wall with his shotgun.
66	* In ''Film/TheMatrixReloaded'', when Agent Smith gains the ability to [[MesACrowd clone himself]], this covers the victim’s body before they [[CloneByConversion transform into a Smith clone]]. Seen again in ''Film/TheMatrixRevolutions''.
67	* 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.
68	* ''Film/NobodySleepsInTheWoodsTonight'': An animated version of this trope, as the black goop is alive. Anyone it possesses becomes a murderous psychopaths with [[BodyHorror growths appearing all over their body]]. Oh, and it also comes from an asteroid that landed on Earth.
69	* In ''Film/Overlord2018'', the substance that the Nazis are experimenting with is literally petroleum tar. However, it contains a chemical found nowhere else except a little town in France that is the active ingredient in their SuperSerum, which is bright red when distilled, which is done by injecting people with the raw tar and extracting it from their blood.
70	* The black liquid in ''Film/{{Prometheus}}'', a potently mutagenic [[OrganicTechnology bioweapon]] made up of millions of small micro-organisms that has the ability to [[spoiler:mutate any Terrestrial life-form in horrible, parasitic ways into rapidly evolving flesh-eating nasties, deadly parasites and rampaging mutants, and can turn a habitable planet into an all out DeathWorld overrun with techno-organic nightmares]].
71	* ''Film/Venom2018'' sees the titular symbiote and its kin naturally take the form of sentient mobile slimes and though all have dark colorations, 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]]]].
72	[[/folder]]
73
74	[[folder:Literature]]
75	* ''Franchise/CthulhuMythos'': Most representations of the shoggoths ({{Blob Monster}}s that are arguably some of the most fearsome non-godlike entities of the mythos) usually has them as gigantic masses of black or very dark metamorphic sludge, from which they constantly extrude and retract limbs, maws and sensory organs.
76	* The blight from the ''Literature/DarkShores'' book ''Dark Skies''. 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]].
77	* In ''Literature/{{Elantris}}'', everything in the once-beautiful, now-accursed city of Elantris is covered in a grimy blackish substance, and anyone who lives there rapidly gets covered in it too. Unusually for this trope, it turns out that it's not fundamentally harmful, can be cleaned off with sustained effort, and has a mundane explanation: it's a type of phosphorescent microbe that made the buildings shine during the city's glory days and that died when the city, in effect, lost its power source.
78	* 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 goo that threatens to engulf anyone in its path -- featured in horrific detail in the [[Film/TheHungerGamesMockingjayPart2 film adaptation]].
79	* ''Literature/ThePrismPentad'': When Rikus's sword, the magical R'Kard's Bane, is snapped, an ominous, tar-like substance oozes from the blade, which is implicitly connected to the Shadow people. A handful of this substance sprayed out of the broken tip spells the end of one of the Sorcerer Kings, while [[spoiler:the Dragon itself is slain when Rikus willingly snaps the sword into his body, dousing him in a growing shower of black slime that kills him from good and forces him into his true form as he dies]].
80	* ''Literature/SkeletonCrew'': In the short story "The Raft", four college students decide to take an end-of-summer swim at a remote lake, and find a carnivorous "oil slick" that eats them one by one. This story was adapted in the movie ''Film/Creepshow2''.
81	* "Literature/Slime1953": The title creature is a black, amorphous {{blob\|Monster}} from the bottom of the sea. In fact, it's so black that it's all but invisible at night; witnesses to its attacks pretty much see their friends and loved ones "taken by the darkness", as though the dark itself were alive and hungry.
82	[[/folder]]
83
84	[[folder:Live-Action TV]]
85	* In ''Series/AmericanGods2017'', [[LoveGoddess Bilquis]] hosts an orgy where several worshippers dance naked. A king tries to overthrow her, and instead has sex with her. When he climaxes, he melts into a black liquid, and the worshippers also melt into another large body of the same liquid that slides into her vagina.
86	* 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 pummeled to stimulate the blood flow and cleanse the poison, whereupon the black blood turns transparent and runs clear until the wound heals.
87	* The [[TheVirus NARVIK-B virus]] in ''Series/{{Helix}}'' modifies its victims' behavior so they become super-strong, paranoid, aggressive and biologically driven to infect others via forcible transmission, which entails assaulting and restraining victims and [[BadBlackBarf vomiting a black secretion]] into their mouths. The [[TechnicallyLivingZombie vectors]] also develop TaintedVeins as their blood turns black, and adding growth factor to a petri dish of monkey blood infected with NARVIK-B results in an [[MeatMoss explosive growth of black biomass]]. The black gunk is such an integral visual motif that it's featured dripping off the "X" in the series TitleCard.
88	* During season 2 of ''Series/LockeAndKey2020'', Eden's odd behaviour prompts Kinsey to take a look inside her MentalWorld using the [[CoolKey Head Key]]; her mind takes the form of a glamorous fashion shop, with the perfume counters displaying her memories... except one counter has been almost completely overtaken by a spreading puddle of tarry-black gunk. [[spoiler:It's because Eden was possessed by one of the demons behind the Black Door in the previous season finale.]]
89	* ''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 (and by "screwing around", we mean, "drags Riker into the tar pit and threatens to have the others kill each other"), he also murders Tasha Yar. [[KilledOffForReal No, she's not revived]].]]
90	* ''Series/{{Supernatural}}'':
91	** Ectoplasm is a thick, slimy substance that is only produced by ghosts that are particularly angry or dangerous; the most common form of it is pitch-black.
92	** The true forms of both [[EldritchAbomination Leviathans]] and [[PrimordialChaos the Shadow]] are shown to be black sludge, which are capable of possessing people through OrificeInvasion.
93	* ''Series/TheXFiles'': The Black Oil is 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.
94	[[/folder]]
95
96	[[folder:Podcasts]]
97	* ''Podcast/TheAdventureZoneBalance'': [[spoiler:The Hunger, an evil sentient plane of existence, is described as tar-like with the coloring of black opal]].
98	* ''Podcast/TheMagnusArchives'': This often pops up in association with [[ReligionOfEvil the People's Church of the Divine Host]], most notably when [[spoiler:Trevor Herbert rescues Julia Montauk from a whole room full of it]]. [[spoiler:This is because the People's Church worships [[GodOfDarkness the Dark]], and the "dark water" is a physical manifestation of the Dark itself.]]
99	[[/folder]]
100
101	[[folder:Tabletop Games]]
102	* One of the monsters featured in ''TabletopGame/DungeonsAndDragons'' is the Black Pudding, a [[BlobMonster living puddle of corrosive black slime]] that engulfs anything and everything it can.[[note]]No relation (presumably) to ''actual'' black pudding, which is one of Britain's many proud entrants in the field of ForeignQueasine, being a sausage made with pig's blood that is culinarily somewhat divisive.[[/note]]
103	* 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.]]
104	* In ''TabletopGame/FabulaUltima'', the Black Blood artifact is a tarry black sludge held in a glass jar. Drinking this sludge allows one to rise from their grave as an undead after being killed. The ''Fabula Ultima Atlas: High Fantasy'' sourcebook suggests this as one possible method for becoming a [[OurLichesAreDifferent lich]].
105	* 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. However, its worth noticing that in old flavor it came in many colors, with variations including green and gold, all with metallic sheen.
106	* ''TabletopGame/{{Pathfinder}}'' also has Black Puddings, as well as 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 nearly every nasty under the earth with either sanity or morals in short supply.
107	* ''TabletopGame/ParanormalOrder'' has thick, pitch black ooze as the most common manifestation of Death, one of the five elements that make up supernatural occurrences in our world.
108	[[/folder]]
109
110	[[folder:Video Games]]
111	* In ''VideoGame/AnotherCrabsTreasure'', the ocean has been polluted with Gunk, a toxic oil-like sludge that doesn't merely poison those that touch it, but [[TheCorruption corrupts their minds]] to [[DespairEventHorizon lose all hope and joy]] until they eventually deteriorate so much that they [[UnanthropomorphicTransformation lose all sentience and turn animalistic]]. Some enemies infected with it even weaponize it as BadBlackBarf.
112	* 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 molding 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.
113	* The eponymous [[MechanicalAbomination Ink Machine]] from ''VideoGame/BendyAndTheInkMachine'' seemingly both runs on ink and produces it in infinite -- and exponentially growing -- quantities. The ink covers the entire studio, and can both bring cartoon characters to life (albeit with a healthy dose of BodyHorror) and turn humans into ink monsters, the most common of which are the Searchers, deformed and incomplete beings of ink, and [[spoiler:the Lost Ones, humanoid masses of dripping, shifting ink]].
114	* 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 {{Fish Pe\|ople}}rson]].
115	* 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 almost indestructible in liquid form.
116	* In Episode 4 of ''VideoGame/CommanderKeen'', the Isle of Tar is one of the three islands located in the southeastern Three-Tooth Lake. It has many pits of boiling black tar which kills Keen instantly upon contact, and at one point he has to go through the deepest pit in order to grab a blue gem and climb back alive (by using some weak platforms to avoid falling). The tar makes an appearance in other levels in the episode, but it's not as concerning in them as it is here.
117	* In the Nintendo DS adaptation of ''WesternAnimation/DuckAmuck'', the game may start a minigame based on the section where the screen frame is used in an attempt to crush Daffy. However, as it would be impossible to move the DS's screen frame in such a way, a thick black ooze instead is used to crush Daffy.
118	* ''VideoGame/EpicMickey'': The game's main antagonist, the Shadow Blot, is an enormous monster made from an oozing black mixture of paint and thinner [[spoiler:by ''WesternAnimation/MickeyMouse himself'' [[NiceJobBreakingItHero messing around too much]] in Yen Sid's laboratory]]. Its corrupting slime has dripped and spread all over Wasteland, creating [[{{Mooks}} smaller enemy blobs]] called Blotlings and causing all sorts of destruction. [[spoiler:Once it's finally destroyed (or [[DefeatMeansFriendship redeemed]]) atop [[DeathMountain Mickeyjunk Mountain]], it turns out to be nothing more than [[FightingAShadow an oversized piece]] of the ''actual'' Shadow Blot, which [[WesternAnimation/OswaldTheLuckyRabbit Oswald]] inadvertently unleashes during a ThirdActMisunderstanding. The real Blot is best described as a [[EldritchAbomination sentient hurricane made of ink]], swirling around [[WhereItAllBegan Dark Beauty Castle]] as it spawns enormous tentacles to suck up all the paint in the Cartoon Wasteland.]]
119	* [[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.
120	* ''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, and can only be destroyed by shooting at the demon eyes that emerge from the tar. It's also potent and sentient enough to possess robots and even create harbingers of evil known as Blight Ganons.
121	* ''VideoGame/MetroidDread'' shows black goo flying around whenever [[spoiler:an X-parasite alters or mimicks an host]]. Previous ''Franchise/{{Metroid}}'' games use some kind of distortion/pixelation effect.
122	* ''VideoGame/MonsterHunter4 Ultimate'': The FinalBoss of the multiplayer campaign, 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.
123	* ''VideoGame/NeedForSpeedMostWanted2012'' 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.
124	* ''VideoGame/NintendoWars'': Oozium 238 from ''Advance Wars: Dual Strike'' is a slow-moving, black blob-like bioweapon developed by the Black Hole army, and is capable of [[OneHitKill instantly dissolving anything it touches]].
125	* In ''VideoGame/Prey2017'', Typhon lifeforms all appear to be composed of moulded threads of glistening black oil, from the tiny shapeshifting Mimics to the gigantic Nightmares, and are uniformly incapable of empathy for anything other than themselves -- hence ongoing threat of AlienInvasion. [[spoiler:Subverted in the finale, in which a Typhon life-form can gain the ability to empathize, potentially saving the day.]]
126	* ''Franchise/ResidentEvil'':
127	** Thick, [[EvilSmellsBad foul-smelling]] black slime is secreted by hosts of the Ourobouros virus in ''VideoGame/ResidentEvil5''.
128	** The FesteringFungus in ''VideoGame/ResidentEvil7Biohazard'' covers many locations in thick sheets of black, oozing mold, and also creates {{Mushroom M\|an}}en comprised of tangled ropes of fungal matter. Worse still, it's also capable of infesting people like [[TheFamilyThatSlaysTogether the Baker family]], enhancing their strength, driving them insane, and [[spoiler:rendering them subservient to [[BigBad Eveline]], who emits this stuff by nature]].
129	* ''VideoGame/Reverse1999'' has Arcana and her primary incantation, a black slime that can mind control people, mutate them into her loyal minions, or even form up into a giant titan that can wreak unquestionable levels of destruction. Fittingly, she is the leader of the Manus Vindictae and the crux of their danger, as without her slime, they wouldn't nearly be as much of a threat with all their [[BrainwashedAndCrazy unwilling recruits sourced from manipulated, desperate masses.]]
130	* ''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.
131	* 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 bubbling 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 gradually manifest, and later-stage infectees are actually ''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.
132	* In ''VideoGame/SlimeRancher'', the Tarr are highly dangerous and widely feared {{Blob Monster}}s that eat the other slimes being ranched by the PlayerCharacter... [[ToServeMan and the rancher]]. Appropriately enough, they're mainly black with subtle rainbow-stripes.
133	* 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, [[MechanicalAbomination 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]].]]
134	* ''VideoGame/SongOfHorror'': One of the calling cards of [[EldritchAbomination the Presence]] is a tarry black ooze. Revenants are slathered with it, the Darkness survival set piece is always kicked off by the walls and ceiling being taken over by it, and a few times throughout the game, it shows up as an obstacle that can only be [[WeakenedByTheLight burned off by particularly intense light]].
135	* ''Franchise/SonicTheHedgehog'':
136	** ''VideoGame/SonicTheHedgehog2'' has Oil Ocean Zone. The black oil that covers the bottom of the level is thicker and nastier than other liquids, and if you fall in it, it will drag you down unless you make a series of rapid jumps to get out again.
137	** ''VideoGame/SonicTheHedgehog4'': Oil Desert Zone is a [[NostalgiaLevel remix]] of Oil Ocean.
138	** The original Oil Ocean Zone returns in ''VideoGame/SonicMania'', and now it gets set ''on fire'' between Acts 1 and 2, resulting in thick smoke that will cause gradual damage unless Sonic periodically pulls switches that dispel it.
139	* ''VideoGame/TwistedWonderland'': Using magic and/or being in a highly troubled mental state causes a dark, toxic substance called ''blot'' to collect in the magic user's system. Allowing it to collect past the person's limit without letting it deplete naturally will cause the person to reach ''[[OneWingedAngel overblot]]'', in which they transform into a dangerously empowered and violent monstrous creature. This state if left untreated will eventually kill the person.

143	* ''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.

147	* In ''WebAnimation/{{RWBY}}'', the Creatures of Grimm are born from pools of black ooze that litter the landscape of [[BigBad Salem]]'s domain. Periodically, a new Grimm will drag itself out of the ooze and continue with their single-minded mission of killing all of humanity. Volume 6 reveals these pools to be the Pools of Annihilation, [[spoiler:the liquified essence of [[DestroyerDeity the God of Darkness]], which carry his terrible power]].

151	* The Treasure Monster in ''Webcomic/TheInexplicableAdventuresOfBob'' is a jeweled mask that can create and control seemingly limitless quantities of creepy black goop, usually molding it into a creepy four-legged body for itself.
152	* 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.

156	* ''Website/SCPFoundation'':
157	** [[https://scp-wiki.wikidot.com/scp-035 SCP-035]] ("Possessive Mask") constantly emits a viscous black fluid from its eye and mouth holes which corrodes anything coming into contact with it, wearing down the specially alloyed cells it's locked in every two weeks and [[PossessionBurnout decaying its hosts to uselessness]] after a few ''hours''.
158	** [[https://scp-wiki.wikidot.com/scp-106 SCP-106]] ("The Old Man") is dripping with a caustic black slime which eats through anything, even the 40 layers of lead-lined steel that lines his cell. The fluid is apparently meant to aid "digestion".

162	* ''WesternAnimation/BatmanBeyond'': Inque is a mercenary who allowed herself to be experimented on for money. Whatever the purpose of the experiment, it left her a dark-hued [[VoluntaryShapeshifting polymorph]] mutant capable of assuming malleable or even liquid forms, hence why she chose the alias "Inque". However, she remains vulnerable to electricity, which messes with her cells, and water, in which she dissolves.
163	* ''WesternAnimation/BojackHorseman'': This 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]].
164	* ''WesternAnimation/{{Centaurworld}}'': [[spoiler:The Nowhere King]]'s physical form is made up of a mass of black ooze that he can control as he pleases.
165	* ''WesternAnimation/{{Pibby}}'': The Static, a dark force consuming the multiverse, takes the form of a tide of black matter covered in colorful static glitches.
166	* ''WesternAnimation/ThePiratesOfDarkWater'' had the titular "Dark Water", an amorphous blob that roams the seas, devouring anything in its path.
167	* ''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.
168	* ''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. It's only when Jack's father fires an enchanted arrow at the substance does it convert Aku into his present-day (and future) form.
169	* ''WesternAnimation/TeenageMutantNinjaTurtles2012'' has the Synthezoids, in the final part of the non-canonical "Mutant Apocalypse" arc. They are pitch black-colored, mutant liquid petroleum blob creatures, which are deployed to guard Maximus Kong's rig truck from any attackers who try to raid it.
