7	->"''That's everyone. They all say it's impossible to reverse it.''"
8	-->-- '''Sam Winchester''', ''Series/{{Supernatural}}'' "[[Recap/SupernaturalS02E17Heart Heart]]"
9
10	Bob has some kind of affliction or state (broadly speaking) -- it might be ThePlague, TheVirus, a SoapOperaDisease, or it might be a {{Metamorphosis}}, ForcedTransformation, {{Transhuman}} state or other transformation. It doesn't necessarily even need to be something wholly negative or detrimental, as Bob can be CursedWithAwesome. This trope can also apply to an outbreak of TheVirus or ThePlague if there are efforts to find a cure for the populace. A magic spell can theoretically also be a case of this trope, but this is rare, usually being a downplayed form of this trope at most where there's a CurseEscapeClause or a CelestialDeadline to remove it.
11
12	Whatever the type of affliction/state, a cure or reversal method isn't readily available. If Bob and/or his friends want it gone, they'll probably look to FindTheCure -- this trope is ''not'' when they succeed in that objective.
13
14	This trope is in effect when Bob or his friends are explicitly told there's no way to reverse or undo Bob's affliction and when that's proven to be the case. How Bob will respond to this information varies, especially if he resents his affliction. Maybe he'll learn to accept his fate and spend the rest of his days with his condition wisely, maybe he'll cross the DespairEventHorizon, maybe he'll be in denial and keep on looking, maybe he or his friends will put him down if his condition makes him a danger to others, maybe he'll TakeAThirdOption via [[BodySnatcher consciousness transferral to an unafflicted new form]].
15
16	If the affliction is the transhuman/transformation type, there can be overlap between this trope and {{Metamorphosis}}, but this trope is specifically where the matter of reversing the change is brought up and the answer to the question is a no. It can overlap with MistakenForDisease if the reason they can't cure it is it turns out not to be a disease -- in fact, the transformative form of this trope might be accompanied by the line, "It isn't a disease" to emphasize why it can't be reversed.
17
18	Note that the question of whether or not there's a cure or reversal method ''must'' be brought up in some form and the answer must be a clear no in order to be a straight example of this trope. If the matter of a cure is not brought up, no matter how irreversible the affliction seems, then it's an ImpliedTrope. Instances where Bob ''does'' find and take a cure but StatusQuoIsGod forces him to regain his affliction or suffer a new replacement affliction do not count as this trope.
19
20	Contrast KeepingTheHandicap, where a "disease"-type affliction or a disability ''has'' a cure but Bob chooses not to take it. Compare TooInjuredToSave, which is where a character is too severely injured and their immediate medical circumstances too inconvenient for them to survive. Not to be confused with NoCureForEvil, which is where evil is incapable of healing.
21
22	It's not unheard of for franchises which run for long enough to initially depict a recurring disease, transformation or transhumanism as incurable, only for a cure to turn up in a later installment, sometimes as a symptom of {{Flanderization}}.
23
24	This trope unfortunately has a significant grain of TruthInTelevision to it in regard to many RealLife illnesses and other ailments, so Administrivia/NoRealLifeExamplesPlease.

31	[[folder:Anime and Manga]]
32	* ''Manga/DeliciousInDungeon'': Izutsumi joins Laios' group to find a way to break the "curse" that makes her an ArtificialHybrid cat-girl. It turns out that not only is the MergerOfSouls irreversible but she isn't a human with cat bits added -- she's a cat with human bits added, so she can't even suppress the magic temporarily. By the end, she doesn't much mind, since she's found friends and personal freedom along the way.

34
35	[[folder:Comic Books]]
36	* ''ComicBook/{{Druuna}}'': Druuna spends much of the comic trying to find a cure for the Morbus Gravis plague that took the life of her lover Shastar and many others, horribly mutating them into barely-sentient monsters. By the end of ''Aphrodisia'', she deciphers a message from the ghost of Captain Lewis that Morbus Gravis cannot be cured. Despondent, she goes back into the dreamworld she just woke up from, praying that someday it will be different.
37	[[/folder]]

39	[[folder:Fan Works]]
40	* ''Fanfic/AbraxasHrodvitnon'': Monster X at one point begs San-Who-Could-Have-Been/Youngest Brother ([[spoiler:Keizer]] Ghidorah's [[spoiler:attached]] [[MultipleHeadCase left head]]) to purge [[Characters/AbraxasHrodvitnonTitansAndOtherCreatures the Many]] from an infected living Titan to save the latter's life, but San-Who-Could-Have-Been's thoughts reveal he and his brothers can't remove the infection once it's set in even if they wanted to.
41	* ''WebVideo/DisneyVillainSongsLydiaTheBard'': In Anna's VillainSong story, the ice magic in Anna's heart, instead of turning her to lifeless ice, is giving her ice powers like Elsa's but also corrupting her personality -- and unlike in [[WesternAnimation/Frozen2013 canon]], Grandpappy informs Anna and Kristoff when they go to him for help that there's no curing it.
42	* ''Fanfic/TheUltimateEvil'': The binding ritual which permanently connects one to their natural [[{{Synchronization}} Other]] is an irreversible process. In the second story, Valerie approaches her Other Shendu to ask how a binding can be severed, and he replies that it can't be undone by anything. The first story's ending did indeed demonstrate that [[spoiler:not even the Book of Ages' reality-rewriting power can undo a binding between Others]].
43	* ''Fanfic/WithThisRing'': Despite consulting multiple groups of Maltusians, who are billions of years old and are also the universe's experts on emotional spectrum technology, Paul has still not found any way to reverse orange light assimilation. If someone has been turned into a construct, the only option to free them is a MercyKill -- and it's not even clear whether the person's soul will survive that, so it might not really be freedom.

47	* In ''WesternAnimation/Wish2023'', once Magnifico uses forbidden magic, he's bound to it forever and there's no way to reverse it.

50	[[folder:Film -- Live-Action]]
51	* ''Film/{{Afflicted}}'': Derek seeks out the vampire who turned him, and when he confronts her he asks her about a cure, only for her to say there's no cure, making it '' very'' clear that if there was a cure (or even a way of killing herself), the centuries-old vampiress would have readily taken it ''long'' ago.
52	* ''Film/Blade1998'': {{Discussed\|Trope}} and {{averted\|Trope}}. When Karen tells Frost she cured herself of vampirism, Frost and Mercury scoff at the notion and Frost tells her there's no cure, to which Karen counters she's discovered there ''is'' a retroviral cure if a vampire was originally human.
53	* ''Film/Deadpool2016'': The title character is hunting the movie's villain Francis so that he can make him reverse the BodyHorror that turning Deadpool into a mutant left him with. As it turns out, to Deadpool's ire, [[spoiler:Francis was lying earlier when he said he could fix Deadpool's scarring. Fortunately, Pool's girlfriend decides she can live with him this way after a brief adjustment period and a bunch of drinks]].
54	* ''Film/TerminatorGenisys'': Having encountered the [[Characters/TerminatorGenisys T-3000]] [[spoiler:John Connor]] and knowing it's basically a {{transhuman}}, Kyle Reese proposes trying to find a way to restore its humanity. Pops, who has files on the T-3000's development in the future war, points out that having your entire body assimilated and replaced with nanobots cell-by-cell isn't the kind of thing that a human ''can'' be brought back from, and he quotes the trope name.
55	* ''Film/TheWitches2020'': Agatha tries and fails to synthesize a cure to the witches' Mouse Maker potion which has transformed her grandson and other children into mice, meaning the mice children are stuck that way for the remainder of their lives.
56	* ''Film/TheWolfman2010'': The gypsies explicitly say just after Lawrence is bitten that there's no cure for lycanthropy. Once Gwen becomes aware of Lawrence's lycanthropy, she looks into finding a cure in the lead-up to the next full moon, and ends up facing the gypsies, who tell her what they told the audience earlier.

59	[[folder:Literature]]
60	* ''Literature/CharlieAndTheChocolateFactory'': After Wonka demonstrates his Wonka Vision machine that transports huge, oversized chocolate bars (as in several square feet and weighing dozens of pounds) to a person's TV as regular sized candy bars, Mike TV excitedly goes into the machine because he gets to be on TV (the [[Film/CharlieAndTheChocolateFactory 2005 adaptation]] shows [[InsufferableGenius Mike]] jumping in because he hates Wonka's MundaneUtility [[ReedRichardsIsUseless for a matter teleporter]]). However, Mike comes out [[IncredibleShrinkingMan a few inches tall]], and when he and his father tell Wonka to just teleport him back so he'll return to normal size, Wonka says that the teleporter's resizing works one way (big things can be made small, not small things made big). The only solution is to take Mike to the taffy room and stretch him, and he's last seen coming out of the factory, not normally proportioned but looking very tall and ''very'' skinny.
61	* ''Literature/HarryPotter'':
62	** [[OurWerewolvesAreDifferent Lycanthropy]] has no cure, although people infected with it may drink Wolfsbane potion to temporarily negate its effects.
63	** In ''[[Literature/HarryPotterAndTheHalfBloodPrince Half-Blood Prince]]'', [[Characters/HarryPotterAlbusDumbledore Albus Dumbledore]]'s right hand has become black. In [[Literature/HarryPotterAndTheDeathlyHallows the next book]], [[spoiler:it's revealed after Dumbledore's death this was because he wore a [[SoulJar Horcrux]] and got his hand cursed. Severus Snape can only state he, with all his knowledge about the Dark Arts, can only slow the curse]].
64	** Maledictus are a type of Animagus who can transform into snakes, with a catch; women ([[OneGenderRace and it's always women]]) who are one will permanently transform into snakes in the long run, and there is nothing that can be done to stop it. [[spoiler:According to WordOfGod, Nagini is a Maledictus. This is shown in full in ''Film/FantasticBeastsTheCrimesOfGrindelwald''.]]
65	* {{Subverted\|Trope}} in ''Literature/WerewolfSkin''. The exposition-providing teacher who seems to know everything about the werewolves in this book says there is no cure. [[spoiler:The protagonist discovers through practice that keeping a werewolf away from their wolf skin (which they need in order to transform) until after the moon peaks will break the curse.]]
66	[[/folder]]
67
68	[[folder:Live-Action TV]]
69	* ''Series/BeingHumanUK'': Season 2 sees Nina join up with Kemp's organization as a volunteer for their experiments in the belief that they can cure her lycanthropy. When she goes to George about this, he at first denies that any cure for their condition exists, but eventually joins Nina. In actuality, it's more of a treatment than an actual cure which suppresses a werewolf's transformation during the full moon -- and even then, it has fatal side-effects which Kemp ''intentionally'' allows so that he can covertly murder supernaturals. Overall, the possibility of turning vampires, werewolves, ghosts or other supernaturals back into humans isn't really touched upon, implying that they're all incurable -- [[spoiler:the SeriesFinale has the main cast seemingly rendering themselves human when killing the Devil break their curses, but the ending hints and a bonus episode confirms that this is actually a LotusEaterMachine]].
70	* The ''Franchise/{{Buffyverse}}'' is a pretty big FantasyKitchenSink, but one of the few transhuman conditions that's truly considered to be incurable is lycanthropy. It can only be treated (or altered by exposure to AnotherDimension), not cured.
71	* ''Series/{{Grimm}}'': After [[Characters/GrimmMain Juliette]] is [[spoiler:turned into a Hexenbiest]] as a side-effect of a spell involving her, she approaches Henrietta for help, only to be told that her [[spoiler:transformation]] can't be reversed. She slowly but surely goes out of control with her newfound powers from there. [[spoiler:Ultimately {{subverted\|Trope}} in the show's last few episodes when Juliette (now Eve) is rendered human after returning to Earth from AnotherDimension which was affecting her Woge, with Diana speculating the Hexenbiest part of her got left behind there (a time reset returns her to her Hexenbiest state).]]
72	* ''Series/{{NCIS}}'': The ''Yersinia pestis'' [[ThePlague bacterial bioweapon]] which infects Tony in "[[Recap/NCISS02E22 SWAK]]" is a mild case. When Gibbs confronts the people responsible, it turns out there is no cure, but the bacterium has a short lifespan, and Tony's immune system subsequently fights the symptoms off on his own.
73	* ''Series/PersonOfInterest'': The VictimOfTheWeek in "[[Recap/PersonOfInterestS02E20 In Extremis]]" is [[WhodunnitToMe poisoned with a lethal dose of a radioactive isotope]]. There is no cure. Reese is able to arrange it, however, so that the man who poisoned him is [[ATasteOfTheirOwnMedicine given a dose of his own medicine]], and the victim [[FaceDeathWithDignity dies peacefully]] with the satisfaction of knowing that his murderer is [[KarmicDeath going out the same way]] he did.
74	* ''Franchise/StarTrek'':
75	** ''[[Series/StarTrekTheNextGeneration The Next Generation]]'':
76	*** When Vulcans reach around 200 or so, a rare few develop a condition called Bendi Syndrome, where every emotion they've bottled up gets telepathically transmitted to everyone within range, causing them to act violently and angry. Sarek is revealed in [[Recap/StarTrekTheNextGenerationS3E23Sarek the titular episode]] to experience this condition, and continues to decay when he boards the ''Enterprise-D'' for a diplomatic mission. Since there is no treatment or cure, all Picard can do is willingly mind-meld to take the brunt of these emotions on himself until Sarek can complete his mission. [[spoiler:Sarek later succumbs to the disease in Season 5.]]
77	*** In the episode "[[Recap/StarTrekTheNextGenerationS4E7Reunion Reunion]]", Klingon Chancellor K'mpec reveals that his enemies have poisoned his bloodwine. He's rather cavalier about there being no cure, since he ''keeps drinking it'' even as he talks to Picard about it.
78	** Picard himself, in a possible future timeline, gets hit with Irumodic Syndrome that starts causing severe memory lapses. Though there is some level of treatment, there is no cure. ''Series/StarTrekPicard'' later reveals that [[spoiler:he does indeed have it, and it proves increasingly difficult to rein in as he goes on an important mission]].
79	* ''Series/{{Supernatural}}'':
80	** [[OurWerewolvesAreDifferent Lycanthropy]] is portrayed as almost-completely incurable, with [[Recap/SupernaturalS02E17Heart the show's first werewolf episode]] seeing Sam and Dean try and fail to cure a werewolf using a bogus method, and being forced to accept at the episode's end after scouring all their sources that there's no curing the werewolf in question. From Season 12 onward, this is {{downplayed\|Trope}} when it's discovered the British Men of Letters have an experimental cure which can work ''if'' the lycanthropy is caught in the early stages of infection.
81	** Transhuman monsters ("monster" meaning the supernatural creatures descended from [[MonsterProgenitor Eve]]) are overall {{implied\|Trope}} throughout the show to be incurable unless their infection is caught in the early stages. On top of the aforementioned werewolf treatment, [[OurVampiresAreDifferent vampires]] can only be turned back into humans if they're fed a special potion ''[[DownplayedTrope before]]'' they feed on blood for the first time.
82	** Dean's future self in "[[Recap/SupernaturalS05E04TheEnd The End]]" mentions that the [[HatePlague Croatoan Virus]] currently ravaging the world is incurable.
83	** A variation occurs in Season 9 with Sam, Dean and Kevin looking to find a way to reverse the effects of the Fall (which has expelled every angel in Heaven to Earth and has destroyed all angels' wings except for Metatron's and the archangels'). Their efforts reveal that according to God himself, the spell's effects are irreversible. That being said, later episodes reveal there is a workaround for the "angels locked out of Heaven" part.
84	** {{Subverted\|Trope}} with [[TheCorruption the Mark of Cain]]. Part of the Season 10 StoryArc is [[FindTheCure finding a way to rid Dean of the Mark]], and when Team Free Will confronts Cain himself on the matter, he bitterly declares there is no cure. However, the SeasonFinale reveals that [[TheGrimReaper Death]] is capable of removing the Mark from a person in exchange for another bearer taking their place, and there's also a powerful spell that can erase the Mark entirely ([[SealedEvilInACan at a cost]]).
85	* ''Franchise/{{Whoniverse}}'':
86	** [[FullConversionCyborg Conversion]] into a [[CyberneticsEatYourSoul Cyberman]], once it's occurred, is usually considered irreversible.
87	*** Notably, the ''Series/{{Torchwood}}'' episode "[[Recap/TorchwoodS1E4Cyberwoman Cyberwoman]]" reveals Ianto has been keeping his half-converted girlfriend Lisa alive in the hopes of getting her restored to full humanity, only for Jack (who has knowledge of Cyber-Empires from TheFuture) to outright tell him, "there is no cure. There never will be. Those who are converted stay that way." Lisa sort-of gets around this by using the Cybermen's tech to transplant her brain into a fully-organic body, but her brain's Cyber-programming sticks.
88	*** In "[[Recap/DoctorWhoS36E12TheDoctorFalls The Doctor Falls]]", after [[spoiler:Bill]] is converted into a Cyberman but fights off the programming, the Doctor vows that he'll fix her. He later admits when she brings this up that he wasn't being entirely truthful: he has hope that she can go BeyondTheImpossible with what he said, but it's unlikely that she'll ever be human again. [[spoiler:Bill finds another way when Heather removes her consciousness from her Cyber-converted husk and turns it into a "pilot" (long story).]]
89	** One of the reasons why Captain Jack wants to find his way back to the Doctor after becoming immortal is to find out if his immortality -- granted by a HumanoidAbomination with temporal power accidentally "bringing him back forever" and turning him into a living anomaly -- can be removed. The Doctor simply tells him there's nothing even he can do about it. That being said, a couple ExpandedUniverse materials have introduced one or two things that are stated to be capable of removing Jack's immortality, and the show's ''[[Series/TorchwoodMiracleDay Miracle Day]]'' season sees the same force which rendered all humans on Earth immortal in turn apparently render Jack mortal (although WordOfGod speculates that it probably only removed Jack's HealingFactor and not his immortality). Then there's the hint that [[spoiler:Jack will slowly transform into the eons-old Face of Boe (who apparently dies for real in the year 5,000,000,000) if his immortality makes him live for long enough]].
90	** In "[[Recap/DoctorWhoS29E5EvolutionOfTheDaleks Evolution of the Daleks]]", the Doctor tells Laszlo that he can't reverse the latter's partial conversion into a [[PigMan Pig Slave]] -- something which has forced him to live in the sewers since escaping the Daleks and causes his girlfriend a great deal of distress when she finds out in [[Recap/DoctorWhoS29E4DaleksInManhattan the previous episode]] -- but he ''can'' extend his formerly-shortened lifespan later on. The episode ends with Laszlo finding a place to belong despite his appearance in Hooverville.
91	* ''Series/TheWitcher2019'': [[Characters/TheWitcher2019Protagonists Yennefer]] gives up her reproductive organs to be transformed into a beautiful woman. Later she wants to have a child and seeks a cure for her infertility, but she is informed by Borch Three Jackdaws that she will never regain her fertility.

94	[[folder:Music]]
95	* "Cure 4 Psycho" by Music/RedHook is about the singer realising that her awful, gaslighting ex is a psycho, and "There's No Cure For Psycho".
96	--> You're just a sadistic piece of shit\
97	Somehow I just couldn't see\
98	But then I looked it up...\

108	[[/folder]]
109
110	[[folder:Tabletop Games]]
111	* ''TabletopGame/AfterTheBomb'': The SyntheticPlague which led to the apocalypse in the game's backstory. By the time it was created, advancements in genetics and medical technology had gotten to such a point that viral disease was no longer seen as a major problem in any form, but the disease was designed with a copy of the human genome which ensured any cure that targeted the disease would also target the host.
112	* ''TabletopGame/{{Warhammer}}'': {{Muta\|nts}}tion from {{Chaos\|IsEvil}} exposure is both irreversible, even to [[HealingHands healing magic]], and a [[TorchesAndPitchforks death sentence]] in polite society. Some [[BackAlleyDoctor Back-Alley Doctors]] discreetly remove the cosmetic effects where possible, but other effects of the mutation persist. Some heretical [[HealerGod Shallyans]] believe that the goddess ''can'' cure mutation, but haven't had any luck actually doing so.
113	[[/folder]]
114
115	[[folder:Video Games]]
116	* ''Franchise/DragonAge'': This is the case for [[TheCorruption the Blight]], which destroys any living thing it touches -- even bacteria. The larger a creature is, the longer it takes for them to die, so humans can be ill with the Blight for months. It's also extremely contagious. The Blight has been presumed to be incurable for centuries InUniverse, and the closest thing to a 'cure' is to become a Grey Warden, which extends the lifespan to roughly thirty years and stops it from being contagious, but even then, the body will eventually succumb to it if they aren't killed in battle first. Possibly {{subverted\|Trope}} as of ''VideoGame/DragonAgeInquisition''; [[spoiler:the Hero of Ferelden (the PlayerCharacter from ''VideoGame/DragonAgeOrigins'') is [[FindTheCure on a quest to find a way to reverse the condition]]. It remains to be seen how successful they will ultimately be]].
117	* ''VideoGame/DwarfFortress'': Some toxins and curses have ''no'' cure nor end, meaning they last until the death of the sufferer. These include mummy curses (less luck for launch) and cave spider venom (permanent dizziness).
118	* ''Franchise/TheElderScrolls'':
119	** Bosmer who undergo the Wild Hunt transform into horrific monsters from the Dawn Era in order to protect Valenwood, but once they've done so they completely lose their minds and, according to the Bosmer Gomini, they're unable to transform back; forcing their brethren to kill them if they don't kill each other first. According to one Bosmer, every monster that currently exists has its origins in a Wild Hunt.
120	** {{Subverted\|Trope}} and {{exploited\|Trope}} with vampirism and lycanthropy. Both are widely believed throughout Tamriel to have no cure, but in actuality, knowledge of how to cure either affliction is suppressed; partly because most of the curing methods are unpleasant at best or immoral at worst, and partly to discourage [[VampireVannabe wannabes]] from getting themselves turned.
121	** Zig-zagged in ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]''. [[BigBad Dagoth Ur]] is spreading the Corprus Disease, created from the divine power of the heart of the series' [[GodIsDead dead creator god]], which turns its victims into insane BodyHorror {{Plague Zombie}}s... while also making them TheAgeless and [[IdealIllnessImmunity immune to all other diseases]]. It is said to be incurable and, naturally, the [[PlayerCharacter Nerevarine]] catches it partway through the main quest. With the help of a [[ReallySevenHundredYearsOld 4000-year-old]] wizard Divayth Fyr, they are "cured", but only of the disease's ''negative'' effects. This actually makes them eligible for the plot's driving prophecy, as "neither blight nor age can harm him". However, they still have the disease, and the "cure" fails on every other patient Fyr tests it on, ultimately zig-zagging the trope.
122	* ''VideoGame/FinalFantasyXIV'':
123	** In the ''Stormblood'' White Mage questline, Sanche suffers from a heart condition that makes exerting herself dangerous and she often collapses from being out of breath while desperately trying to chase off any Gridanians who could meet her daughter Gatty. While the Warrior and Sylphie are able to gain her trust to try to treat her, Master E-Sumi Yan admits Sanche's condition is too severe to save her even with a powerful White Mage and a Padjal conjurer tending to her. [[spoiler:Sanche succumbs to her illness at the end of her questline, as a voidsent named Camamotz made her ill to drive Gatty mad with grief and feed on their aether.]]
124	** In ''Shadowbringers'', the dwarves of Tomra once suffered from a plague known as "stoneblight" that was inevitably fatal and had no cure, forcing the village elders to isolate the afflicted deep in the mines to avoid infecting the rest of the village. This swift and decisive action is said to have saved the Tomran dwarves, who revere the elders' actions as a ShootTheDog moment a century later. [[spoiler:{{Subverted\|Trope}}, as in truth, Lamitt (one of the Warriors of Light from before the flood) was able to venture deep into the ruins of Ronka to devise a cure from the ancient magics there. The formerly stoneblighted dwarves were none too happy about being left for dead and decided to remove their helmets and leave Tomra in protest. To maintain order and their own political standing, the elders exiled Lamitt along with the stoneblighted dwarves, who all perished in the Flood, allowing the Elders to [[WrittenByTheWinners perpetuate their own self-serving narrative]].]]
125	** Primals can 'temper' people enthralling their minds into worshipping them and doing their bidding.. There is no known way to reverse this, and no defense save the Echo, a rare power possessed by the PlayerCharacter and a very few others. Tempered individuals are usually put to death to prevent them from empowering the primals with worship. [[spoiler:However, in 5.4, Allisae is able to develop a spell to reverse tempering, using knowledge learned from a scholar of souls on the First, and the lost research of an Allagan scientist.]]
126	* ''Franchise/{{Halo}}'': Finding a cure for Flood infestation is one of the major reasons for the Halo installations, though no headway to speak of has been made in 100,000 years of research. It is suggested that ancient humanity may have discovered a cure, but the knowledge was lost when the [[{{Precursors}} Forerunners]] devolved them. In ''Literature/TheForerunnerSaga'' prequel trilogy, [[spoiler: it's clarified that ancient humanity ''thought'' they had discovered a cure, but in actuality the Flood was deliberately tricking them, pretending to be "cured", so it could play the long game and take down the Forerunners later.]]
127	* The Green Flu in ''VideoGame/Left4Dead''. It's not for lack of trying; the virus mutates too frequently and erratically to pin down, making the paternal "carrier genome" the closest thing to immunity.
128	* ''VideoGame/{{Transistor}}'': The Limiter notes on [=BadCells=] notes that their transformation, which is unwanted, "they become something else, something they don't seem to want to be." is irreversible:
129	-->this is no conversion but a total metamorphosis, it cannot be reversed as far as i can tell.
130	* ''VideoGame/VampireTheMasqueradeBloodlines'': One of the [[SuperLoser Thin-Bloods]] holds out hope that he can cure his vampirism with a [[SuperhumanTransfusion blood transfusion]] or by [[NoOntologicalInertia killing an imaginary "head vampire"]]. You can tell him the truth gently or [[VideoGameCrueltyPotential sell him bogus equipment]] for the "cure", potentially getting him killed.
131	[[/folder]]
132
133	[[folder:Western Animation]]
134	* ''WesternAnimation/{{Arthur}}'': In "[[Recap/ArthurS13E9ParadiseLostThePrideOfLakewood Paradise Lost]]", Kate and Pal are devastated to find out that as they get older, they will understand each-other less and less to the point where Kate will eventually forget she could even talk to Pal. When they seek advice to reverse or at least stop the process before it gets worse, they're told the process is irreversible and there's nothing they can do about it. However, they feel better when they talk to Grandma Nora's dog, who tells them they don't need to have full conversations to communicate, and just a few words, barks and body language are enough to let each-other know what the other is trying to say and how they feel.
135	* ''WesternAnimation/{{Gargoyles}}'': In one episode, the villainous gargoyle Demona starts the episode by hitting the main cast's [[FriendOnTheForce human friend Eliza]] with a poison dart, then tells Eliza to have [[TheLeader Goliath]] face Demona if he wants the cure. Eliza was actually protected thanks to [[PocketProtector the dart bouncing off her badge that was under her shirt]], but Goliath goes to meet Demona anyway since he wants information. The entire night turns into a lethal game of cat and mouse as Demona tries to kill Goliath. The next day, frustrated by being unable to kill Goliath, Demona flees rather than continue fighting, but first screeches that there never was a cure for the poison and Eliza is surely dead by now. Goliath and company decide it's best not to correct Demona about Eliza being alive.
136	* ''WesternAnimation/JackieChanAdventures'': In the [[Recap/JackieChanAdventuresS5E13ThePowersThatBePart2 series finale]], following Drago's empowerment with all eight Demon Chi, Uncle approaches Shendu to ask if he knows of a way to depower Drago. Whilst the Demon Chi were previously removable when they possessed hosts individually of each-other, Shendu's response reveals that once all eight of the Demon Chi are united inside a single host, "nothing can remove them -- ''ever''." When Uncle and Tohru's reversal spell begins sucking the Demon Chi and all the extradimensional demons Drago summoned into the Netherworld, the Ice Crew's Demon Chi (one demon's powers for each of them) is pulled out of them, while Drago just gets pulled in with the Demon Chi still inside him.
