This character simply ''can't'' die. This is because they are both of the following:

# TheAgeless - The character does not age.
# NighInvulnerable - The character is completely or almost completely immune to harm of any kind. The character may be MadeOfDiamond, an IntangibleMan, capable of [[FromASingleCell regenerating their body under any circumstances]], or even [[ResurrectiveImmortality resurrects completely healed]] every time he's killed. (Note that characters who are invulnerable but who age as normal are simply NighInvulnerable, ''not'' immortal.)

Most {{Physical God}}s or PowersThatBe fall into this category, as do a lot of [[CosmicEntity Cosmic Entities]] and {{Anthropomorphic Personification}}s. A TimeAbyss will tend to be this as well, as accidents tend to happen over the millennia, and invulnerability is needed to keep them going. Most fictional ''souls'' also fit under this, if the work contains evidence of their existence. Ghosts can be banished to the underworld or sent on to the next life but not killed. Though there are [[OurSoulsAreDifferent exceptions.]]

This form of immortality can often be seen as a [[WhoWantsToLiveForever curse]] [[LivingForeverIsAwesome or a blessing.]] This is also the end-goal for the most ambitious {{Immortality Seeker}}s, although it's rare indeed for them to achieve it. More commonly they have to settle for lesser and more impaired forms of immortality like {{Soul Jar}}s, [[FountainOfYouth Fountains of Youth]], or [[LifeDrinker Life Drinking]].

This is a subtrope of {{Immortality}}.



[[folder:Anime and Manga]]
* Garterbelt from ''Anime/PantyAndStockingWithGarterbelt'', who was a JerkAss up until he got killed, then, with the blessings of God, became immortal and lived through all of the world's history from the dinosaurs to the present. [[spoiler:In Episode 13, it appears he's killed. Twice. However, he always put himself back together afterwards.]]
* ''Anime/DragonBallZ'':
** The {{Filler}} and NonSerialMovie villain Garlic Jr. wishes for immortal life from the Eternal Dragon and actually gets it. The only thing that stops him is knocking him into a dark prison called the Dead Zone (which presumably would kill anyone mortal), and the first time that didn't take. The second time around he has no way of ever getting out of there again[[note]]Technically, he ''could'' be freed if someone wished it with the Dragon Balls, but of course no one will do that.[[/note]], and will foreseeably [[ImmortalityHurts be stuck there for all eternity]] while drained of most of his power.
** Achieving this kind of immortality was the reason that Frieza wanted the Dragon Balls of Planet Namek, in order to extend his reign as "the most powerful being of the universe" for eternity.
* The BigBad from ''Anime/NinjaScroll''. If there was a way to kill him, none of the other characters found it.
* Cars from ''Manga/JoJosBizarreAdventure'' part two. After he wears the Stone Mask with the Red Stone of Asia he becomes a god, immortal and incapable of aging.
** He's completely immune to Hamon and the sun - the Pillar Men's only weaknesses - as well. The only way to stop him was to launch him into space [[AndIMustScream to drift for all eternity.]]
** Notorious B.I.G., Carne's Stand from Part 5, is utterly invincible, because [[spoiler:the trigger for its emergence was its user dying, and Stands can only be defeated by defeating their user, leaving it with no vulnerability]]. Eventually the heroes just fling it into the ocean, where it occasionally attacks passing freighters.
* In ''Manga/{{Nobunagun}}'', Saint-Germain is heavily implied to be this. In Episode 9 his car explodes with him in it, and he shows up later completely unharmed, while Episode 10 shows that he's [[ReallySevenHundredYearsOld over 1,000 years old]].
* This happens to [[spoiler: Madara Uchiha]] in ''Manga/{{Naruto}}'' upon [[spoiler:being brought back to life with Edo Tensei, then preventing it from being canceled on himself]]. He later sacrifices this as he couldn't reach his endgame while in that state.
* Every Wu in ''Manga/SazanEyes''.
* Free the werewolf from ''Manga/SoulEater''. He's hundreds of years old but still looks in his prime and no amount of injury has been shown to outpace his HealingFactor. Crona's comment about [[AnthropomorphicPersonification Asura]] being unkillable, as the embodiment of an abstract concept, ''may'' mean he's this were it not for the fact that one of his fellow entities claimed Asura was responsible for the death of some of the others and [[spoiler: Shinigami being replaced by Kid shows explicitly that the Great Old Ones can, after a fashion, die.]]
* Immortals in ''LightNovel/{{Baccano}}'' obtain this form of immortality from drinking the [[ImmortalityInducer Grand Panacea]]. Not only do they not age, but they reconstitute themselves on a molecular, if not atomic, level. The only way to kill an immortal is for another to [[CannibalismSuperpower "devour"]] them.
* ''LightNovel/ACertainMagicalIndex'':
** Fraulein Kreutune, a mysterious woman who has been around since at least the Middle Ages. She doesn't age and she is seemingly completely indestructible. She had been tried as a witch in the past, but nothing the executioners did could harm her. When Accelerator, who is known for pulverizing buildings, punches her, it only knocks her back a little.
** The ''Miracle of Endymion'' movie introduces Ladylee Tangleroad, who gained immortality from consuming ambrosia during The Crusades. While she can feel pain and get injured, she heals from anything, even getting sucked into space. Tired of her long life, she attempts to destroy the world, thinking this will be enough to kill her. When she is stopped, she falls into despair when Index says not even ''that'' would have been enough.
* [[BigBad Black Wizard Zeref]] of ''Manga/FairyTail'' is immortal because he angered a deity of life and death with his research into resurrection. Since that time he has not aged a day and nothing on Earth-land seems powerful enough to kill him. He went so far as to create a bunch of powerful demons, hoping they could pull it off, and abandoned them when he realized they could not. Zeref hopes that his greatest creation, E.N.D., will someday become powerful enough to do it.
** [[spoiler:It's later revealed that Fairy Tail's founder, Mavis Vermillion, also suffered this, but didn't realize it]].
** They later discover the CurseEscapeClause in the cruelest way possible. [[spoiler:The deity that cursed them both did it to deny them happiness. When they believed they found a way to subvert this by finding EternalLove with each other, Zeref's Curse was strengthened by their love to the point that it was able to kill Mavis despite her own Curse.]]

[[folder:Comic Books]]
* Doctor Manhattan from ''Comicbook/{{Watchmen}}''. The only thing that slows him down is the same thing that gave him his powers, and since he already overcame that problem to begin with, it's more of a minor hindrance than anything else.
* [[DependingOnTheWriter In some incarnations,]] Franchise/{{Superman}}.
** Doomsday. Stronger and tougher than Superman, has AdaptiveAbility against anything that does manage to injure him, rapidly regenerates and even if you do "kill", he can regenerate back to life. In theory, he becomes more and more this trope with time as you can't kill him the same way twice.
* Lobo. Not only does he have a HealingFactor that allows him to regenerate out of [[FromASingleCell a pool of his own blood]], he has been banned from entering either Heaven or Hell, or to be more specific, every eternal places like Valhalla.
* Mammoth Mogul from the ''ComicBook/SonicTheHedgehog'' comics, is essentially an AlternateCompanyEquivalent of Vandal Savage. When he finally realizes he can't beat Sonic, he decides to simply wait until Sonic is too old to oppose him.
* ComicBook/GilgameshTheImmortal is a king of ancient Uruk who met an alien that made him completely immortal as them, using his alien ImmortalityInducer. He then goes across all human history: Assyria, ancient Egypt, ancient Rome, Crusades, middle ages, conquest of the Americas, Napoleonic wars, WWI, WWII, cold war, nuclear holocaust, AndTheAdventureContinues...
* In ''ComicBook/NoHero'', [[spoiler: Carrick Masterson is immortal. He can't age or get hurt by anything. He does feel pain. That's it.]]
* In the MarvelUniverse Amatsu-Mikaboshi was revealed to be this, being as it is the AnthropomorphicPersonification of the nothingness before Creation. It is not only older than the universe, it is older than the universe before that and the one before that, stretching back to the Beginning.
* In a more limited sense, the members Cosmic Compass who represent the {{Anthropomorphic Personification}}s of key universal concepts, such as Eternity, Infinity, Oblivion and Death, could arguably qualify, since they always exist so long as the universe does and when a new one comes along will exist in that one also, so though they do ultimately die when it ends they may also be reborn. Each of them are aspects of identical entities who operate on an even grander multiversal scale.
* In ''ComicBook/GreatLakesAvengers'', this is the only superpower Mr. Immortal has. One story reveals he's destined to live until the end of the universe.
* In Creator/PhilFoglio's adaptation of ''ComicBook/MythAdventures'' the evil socerer Isstvan has been cursed with immortality. You can blow him up and all the bits will just squelch together again (fortunately along with his clothes).
* Neil Gaiman's ''[[ComicBook/TheSandman Sandman]]'':
** [[ExactlyWhatItSaysOnTheTin The Endless]], being {{Anthropomorphic Personification}}s of universal constants, are immortal for as long as this version of the universe exists (Destiny is said to have been the first thing to exist in it, and Death will be the last). Killing them is about as possible as killing laws of physics. [[spoiler:That said, the Endless can be 'killed' in a fashion; at least their current versions/incarnations can (with great difficulty). This causes another incarnation of the same Endless to take their place, with the same powers and station and all their memories, but a somewhat different core personality. Despair is said to have died at least once, and by the end of the series Morpheus has too; replaced by Daniel Hall.]]
** Because of Death's immortality, an aspect of her becomes mortal for one day each century to keep her in touch with the lives she collects. [[spoiler: At the end of the day, the mortal form dies, and she's waiting for herself.]]
** Morpheus's friend and drinking buddy Hob Gadling found out early that due to Death agreeing to never take him unless Hob specifically asked to be taken, he's not only immune to aging but quite immune to fatal conditions as well. Though he's not immune to the pain ''caused'' by those fatal conditions. At the end of the series he's over 500 years old and counting, with no plans to stop any time soon.
* The Winslow, in ''[[ComicBook/BuckGodotZapGunForHire Buck Godot: Zap Gun for Hire,]]'' is truly indestructible, hypothesized to be the platonic ideal of a fuzzy green reptile. This scares the piss out of much of the galaxy.
* The Flying Dutchman and his crew in Creator/TomHolt's ''Literature/FlyingDutch''. They drank a magical potion--by accident--and now they can't die no matter how hard they try, and have an unbearable stench that makes them unable to come ashore, except for a brief period every seven years when the stench fades. One crew member spends all his free time jumping from the crow's nest in the hopes that maybe ''this'' time, he'll finally die.
* {{Deadpool}} and {{Thanos}}. In addition to being insanely tough to kill in the first place whether it's due to a HealingFactor or being a NighInvulnerable PhysicalGod, both have at one point in their lives been inflicted with curses that rendered them untouchable to the Abstract Entity of Death. They could not die because Death itself could not claim them. Immortality doesn't get much more complete than the metaphysical concept of Death itself having no power over you. In their case it's a curse because they are both in love with Death.
* Comicbook/DoctorStrange foe [[EldritchAbomination Shuma-Gorath and his fellow Many-Angled Ones]] can't die. Even if their physical forms are destroyed (a feat that usually requires the aid of another CosmicEntity or using the Many-Angled Ones' own power against them), they will simply regenerate them over time. If someone used their power against them to do it, they will simply reincarnate themselves [[DemonicPossession inside the people who "defeated" them this way]]. They are EnemiesWithDeath, and Death is usually outmatched.
* Creator/AlanMoore's "The Big Chill" examines this trope in relation to the other absolute of the heat death of the universe. It's set at a time so close to the end that even almost all immortals have died already as the universe itself winds down. The last survivors who have banded together are the superhero Mister Majestic, another superhero from another dimension, a vampire, a hyperintelligent strain of syphilis, the WanderingJew, a demon, a god, the computer calculating all the names of God, and the abstract spirit of arithmetic. Even they all know their immorality is not going to last.

* In ''Fanfic/KeepersOfTheElements'', all of the Immortals are this, but [[BigBad Radcliffe]] is losing his.
* In ''Fanfic/RedLightning'', [[spoiler: Jimmy]] is this thanks to the storm, that happened in the year 50BC.
* MassivelyMultiplayerCrossover story ''Fanfic/BloodAndRevolution'' has people with varying levels of immortality, and kami, chaos demons, and angels seem to fall here (aside from the GodNeedsPrayerBadly that can kill them, and in some cases the possibility of losing their 'connection' to whatever location or idea they represent). This means that Rune, Kaworu, Folken, Bakura, and eventually [[spoiler:Saitou, Shun, and Aoshi]] all have CompleteImmortality.

[[folder:Film - Live Action]]
* In a similar vein, {{Satan}} in ''Film/EndOfDays'' mocks TheHero for thinking he can beat him, since ''"you are just a man, and [[LargeHam FOREVER]]"''.
* Almost all ghosts in ''Film/{{Ghostbusters}}'' that are not at least a Class 7 are this, which is why they get trapped and sent into the containment unit. [[VideoGame/GhostbustersTheVideoGame the video game]] elaborates that they are capable of crossing over into the SpiritWorld, but the ones that stay in this plane are the kind that have nothing better to do than torment the living.
* Ramin Bahrani's short film, ''Film/PlasticBag'', ends with a lamentation by [[Creator/WernerHerzog the narrator]] that amounts to "I wish I could die."
* In ''Film/{{Wishmaster}}'' the Djinn claims to be this, to justify why nobody can simply wish him to die- as an eternal being, he simply ''cannot'' be destroyed. The way he proves this is pure BlackComedy. When the heroine of the first movie wishes that he blow his brains out, he pulls out a revolver and shoots himself in the head. He's perfectly fine afterwards, though he tells the heroine "it hurt like hell!"
* The Monster, From ''Film/NoSuchThing''. Problematic since, after having lived from the dawn of time to the present day, he is quite tired of being alive and wishes to finally find an end, but nothing can harm him, let alone kill him.

* Jason and Anna in ''Literature/FindingGaia.'' [[spoiler:Subverted at the end of the book.]]
* The Tucks in ''Literature/TuckEverlasting.'' They don't age, and nothing they've encountered yet can kill them.
* Eru from ''Literature/TheSilmarillion'' and Tolkien's other works is also this, being an {{Expy}} of {{God}} Himself. The temporal, physical world was created partly for death to exist in the first place, in order to resolve the climactic conflict between Good and Evil.
** [[GodOfEvil Morgoth]] is the only true example of this in Middle-Earth. The elves are TheAgeless, and most other Valar and Maiar ''can'' have their bodies destroyed, but can just make new ones. But Morgoth turned the ''entire planet'' into his SoulJar, meaning he literally cannot die until the end of time. Doesn't save him from being a SealedEvilInACan at several points, but technically he's ''still'' out there, waiting...
* The Ellimist and Crayak, from Creator/KAApplegate's ''Literature/{{Animorphs}}'' series. While not all-powerful, they are quite god-like, often use the Yeerks and the Animorphs as [[CosmicChessGame "chess pieces"]] in their game, and have been living for thousands if not millions of years.
* Windle Poons from ''Discworld/ReaperMan.'' He returns as a zombie, and despite the best efforts of his colleagues (and himself), he just ''will not die''. However, it's possible he wasn't really a zombie, due to [[DeathTakesAHoliday Death Being Fired]], as other zombies are apparently capable of dying or at least being harmed.
* ''TheDivineComedy'': Not only God, but all souls are subjected to this kind of immortality, no matter if they are in Hell, Purgatory or Paradise. [[CaptainObvious Their mileage varies about this status.]]
* Creator/HPLovecraft's Great Old Ones, or at least Cthulhu, have this form of immortality. In ''Call of Cthulhu'' Cthulhu gets a boat driven through his skull, turning his head into green paste. It reforms pretty much instantly. In writings of one of the later mythos writers, he's also gotten vaporized by a nuclear strike, only to reform himself. According to some writers, they can be killed by another Great Old One (or other godlike entity) while other sources state that they are completely unkillable.
** Since even the Great Old Ones like Cthulhu are utterly insignificant in the grand scheme of the universe [[spoiler:Cthulhu himself will ultimately die cold and alone on the barren Earth.]]
* Max Frei's ''Literature/LabyrinthsOfEcho'':
** "Invisible elves" - the elsidiayas are immaterial beings who somehow inhabit items and sometimes communicate with other sentients. There is no information suggesting that elsidiayas age, can be hurt or can die at all.
* Galla in Vadim Panov's ''Literature/SecretCity''. Galla is for all ends and purposes a PhysicalGod; according to his own recollection, he is merely the first thing / being created. Assuming he's telling the truth, his creator, the one and only creator and keeper god of the universe, obviously also fits the trope.
* Iar Elterrus' works:
** The elements / paths in ''Burden of the Emperor'' series - Light, Darkness, Life, Knowledge and Wrath. They are alive and sentient, as Darkness once actually responds to an adept sacrificing souls of slaughtered enemies with a dismissive sneer.
** The 9 controlling entities of the ''9 Swords'' {{Multiverse}}, each split into Power, Knowledge and Will. The Incarnations of Power and Will, always a dragon and a human (maybe humanoid), are technically mortal and reincarnate as needed. The incarnations of Knowledge, the eponymous Swords, can at best be sealed or fragmented, but never destroyed.
* Certain entities in ''Literature/TheDresdenFiles'' such as gods and the Faerie Queens are absolutely unkillable under normal conditions. Even if their bodies are reduced to their constituent atoms, they will eventually recover completely. However, there are certain places and times where this does not apply [[spoiler:such as on Halloween]], and they can be killed just like anyone else. Provided, of course, that you can get past the defenses of a PhysicalGod. [[spoiler:And then there is the fact when the Faerie Queens do die, the mantle of their power will go into another mortal. If the mortal doesn't have enough strength of character to resist the mantle, then in due time the mortal will become a copy of the Fae Queen that came before.]]
* Lord Foul the Despiser in Literature/TheChroniclesOfThomasCovenant. He has been reduced to nigh-powerlessness numerous times, but always comes back. Much like Tolkien's Morgoth, he is the Creator's evil counterpart in some way, and at least within shouting distance of his power, but imprisoned. Unfortunately, this means that the other inhabitants of the world have to deal having him as an immortal source of evil messing everything up.
** There's some crossover with ResurrectiveImmortality as well. The discreet entity that is Lord Foul ''can'' be killed, though doing so requires a tremendous amount of power and effort, but the cosmic principles he embodies are eternal, and eventually can always coalesce into Lord Foul the Despiser once again.
* ''Literature/FirebirdLackey'' has the Katschei, unless his heart is destroyed at his feet. Wounds instantly heal and he cannot bleed, age, or die.
* Dementors in ''Literature/HarryPotter'' have no soul and cannot be killed. You can merely slow their breeding.
* In the ''Literature/YoungWizards'' series, the most powerful of the PowersThatBe (including the [[{{Satan}} Lone Power]]) exist mainly outside of time, and the mortal characters only ever encounter [[FightingAShadow fragments of them which have been inserted into the timestream]]. Since death is something which takes place ''inside of time'', those Powers couldn't die ''even if they wanted to''.
* In Creator/DavidEddings' {{Tamuli}} (which retcons it to have also been true in the Elenium), Bhelliom and Klael are immortal beings who vie for control of the planets Bhelliom creates. Their fights can kill gods and destroy planets, but they can never actually harm each other, they can only banish each other from the planet they're currently fighting over. In the same series [[spoiler:Zalasta, who turns out to have secretly been the bad guy all along]] becomes effectively immortal, but not in a good way. He is trapped in a frozen moment of time and set on fire by the troll gods, so he will be burning to death for eternity, but can never age or actually die.
** In Literature/TheBelgariad and Malloreon the remaining "prophecy", essentially the sentient spirit of the universe, fits this trope. UL, father of the gods, probably does as well, as would the king of Hell who is implied to have power close to that of UL. The other gods are more open to debate. One is killed, but this is only because he was a mistake to start with. Whether any god could be killed when the universe itself isn't trying to get rid of them is never addressed.
* Discussed with respect to {{God}} in Creator/OrsonScottCard's ''The Worthing Saga''. A village that has been protected against all pain and suffering for as long as anyone can remember suddenly has that protection withdrawn, leading one little girl to speculate that GodIsDead. Her father scoffs, saying that God cannot die because He is TheOmnipotent. The girl replies that He must therefore have the power to die if He wants to. The question remains up in the air because it turns out [[spoiler: that their protection did not come from a divine source, but from immensely powerful human psychics, who DID self-terminate. If God exists in the setting, we never see Him.]]
* In ''The Participants'' by Brian Blose, observers sent into the world to watch it on behalf of an absent creator are complete immortals. Any damage done to their bodies (including death) is reverted within five minutes. This can be inconvenient, such as when your colleagues bury you alive for hundreds of years as punishment for participating too much in the world.
* Elves in Creator/MCAHogarth's ''Literature/TheBloodLadders Trilogy'' go beyond simply being TheAgeless and also have a HealingFactor that makes it hard to kill them without cutting them to pieces and burning the pieces. However, as they get older their immortality uses up more and more of their innate magic, most of the race can't do more than light a candle without draining magic vampirically.
* The Undying from ''[[Literature/{{Somewhither}} Tale of the Unwithering Realm]]''. They come from the alternate Earth called "Cainem", where humanity was never exiled from the Garden of Eden, and so they cannot ever die--they regenerate all injury and can reassemble their bodies when dismembered. This is not necessarily a good thing; there's a reason they're called "Those Who Seek Death in Vain". Seeing as they cannot die and are still capable of feeling pain, this lets the villains go wild when coming up with interesting and exciting means of torture, and they're suspectible to AndIMustScream situations.

[[folder:Live-Action TV]]
* ''Series/BuffyTheVampireSlayer'': The Mayor is this during the 100 days before the Ascension.
* ''Series/TheXFiles'': Alfred Fellig in "Tithonus" was this until [[spoiler: he managed to look into Death's eyes.]] It is possible that he passed this condition to [[spoiler: Scully.]]
* Captain Jack Harkness in ''Series/{{Torchwood}}'' and ''Series/DoctorWho'' is this. Blow him up and the body gradually begins to reassemble. He has been stated to age ''very'' slowly. It's suggested that he may become the Face of Boe, who did die, but whether that's an in-joke or truth was answered with a ShrugOfGod, the writer saying that the joke stops being funny if we know if it is ''or'' isn't true.
* ''Series/{{Supernatural}}'':
** [[TheGrimReaper Death]] claims that he is the one thing in existence that will last forever after [[DidYouJustPunchOutCthulhu he reaps GOD]] at the end of time, although he's so old that he can't even remember anymore which of them came first. Though Crowley mentions that there are rumours he can be killed with his own scythe. [[spoiler:The S10 finale seems to confirm this.]]
** The S10 finale reveals that [[spoiler:The Mark of Cain]] makes its bearer so strong that even ''Death himself'' doesn't know of any way to kill someone who has it. [[spoiler:The Darkness, the entity that the Mark contains, is probably also an example, given that the combined might of God and the Archangels could not kill it.]]
* The evil liquid entity Armus in the ''Series/StarTrekTheNextGeneration'' episode "[[Recap/StarTrekTheNextGenerationS1E22SkinOfEvil Skin of Evil]]" is stated to be immortal and unkillable. He has already spent an immeasurable amount of time on a barren, uninhabited planet after his creators left him there. [[spoiler:Picard ensures that [[AndIMustScream he will be trapped there for as long as possible without any means of escape]].]]
* On ''Series/{{Misfits}}'', this is Nathan's power [[spoiler: until he sells it for twenty grand and gets [[RealityWarper minor reality warping]] instead]].
* Maryann Forrester in ''Series/TrueBlood''. As a maenad, she is at least [[ReallySevenHundredYearsOld as old as ancient Greece]] and is allegedly [[TimeAbyss older than written history]]. She's also completely unkillable; her immortality is based on her beliefs, which means that [[ClapYourHandsIfYouBelieve as long as she believes she's immortal, nothing can kill her]]. [[spoiler:The only way to kill her was to make her believe that her god needed her to die.]]
* The ''Series/{{Smallville}}'' version of Clark Kent. In one episode, a boy is able to see how people will die when he touches them. He touches Clark Kent and does not see a death, only some funky visual effects.
* It's implied in the ''Series/MrYoung'' episode that Ms. Byrne has this, as when Adam shouts "I'm gonna be here forever!" she replies "You get used to it. [[Really700YearsOld The first thousand years are the toughest.]]"
* Henry Morgan in ''Series/{{Forever}}'' has been physically 35 for [[Really700YearsOld 200 years]] and is teleported into the nearest body of water whenever he dies, where he wakes up perfectly fine ([[NakedOnArrival and naked, unfortunately]]). Another immortal posits the the only way for him to die is to be shot by the same pistol the caused his first death, [[spoiler: but the finale proves this theory wrong, so Henry is an absolutely straight example of this.]]

[[folder:Myth, Legend, Oral Tradition, and Religion]]
* {{God}} is usually understood to be this, being the Creator of absolutely everything, including Life, Time, Space, Death and whatever happens after or outside it.
** Lowercase-G gods tend not to be, though with the afterlife as part of their domain, death can be significantly less inconvenient for them than it is for a human.
*** A notable exception being the gods of Myth/GreekMythology. They, and their ancestors the Titans, had complete immortality, which is why the Olympians did not die when their father Cronus ate them as infants (and they emerged alive and full-grown when he was forced to vomit them up). Likewise, this is why the Olympians imprisoned most of the Titans in Tartarus. As true immortals they could not even kill each other.
*** Actually not even the Greek Gods have this. Ouranos, the first Sky god who fathered the Titan was said to cut into a thousand pieces by this son Cronus and is still alive. Likewise Hephaestus, who was thrown from Mt. Olympus has a permaneant limp. Even Zeus himself once had his muscle tendons(all of them) ripped off by Typhon. They possess they possess the Ageless and are immune to natural death, but they are more in line with SuperToughness than true invulnerability.
* How much it counts as this trope when the person in question already has died once may be debatable, but it's definitely a feature of quite a few religious traditions' afterlives -- once you're there, you're not generally thought to have to worry about ever dying ''again'' (though [[OurSoulsAreDifferent exceptions aren't unknown]]).

[[folder:Video Game]]
* VideoGame/DarkSouls : The Everlasting Dragons were said to have had this kind of immortality, and the one example of a true Everlasting Dragon the player encounters in the game is completely impervious to any of the player's attacks. The source of their immortality was their scales. Unfortunately, if the scales are gone all bets are off. [[BoltOfDivineRetribution Lighting]] is great at removing the whole "immortality" thing.
** The Primordial Crystal also grants immortality if used correctly. The crystal itself is fragile, however.
** Undead/Hollows also do not age and have ResurrectiveImmortality, but they suffer from a form of ResurrectionSickness that makes them more mindless each time. Undead are imprisoned rather than executed because they just get back up, the (Undead) player character [[{{Determinator}} can't be kept down]] and Hollow enemies infinitely respawn. Undead [=NPCs=], however, stay dead. [[GameplayAndStorySegregation This is probably for balance reasons]]--it's implied they ''do'' come back, presumably as Hollows, you just don't see them (or can't tell them apart from any other hollow). The series goes back and forth on whether or not Undead can permanently die if killed after fully Hollowing; there are implications either way.
** In the second game, Lord Aldia was obsessed with immortality, and spent the last years of his life researching it as a way to escape the Undead Curse, including an effort to re-create the Everlasting Dragons of old (which failed). In the ''Scholar of the First Sin'' edition: [[spoiler:Aldia actually appears to have succeeded in making himself truly immortal... by purging himself of any semblance of either humanity or a soul, and existing as a twisted, shapeless mass of flesh, tree roots, and fire. It's unclear whether or not he's happy with this result. Even when the player "kills" him in their fight, he continues speaking as if nothing happened, and no souls are absorbed from defeating him.]]
* VideoGame/MetalGearSolid2SonsOfLiberty had Vamp who was invincible because his nanomachines healed his body at an accelerated rate. The only way to kill him was in [[VideoGame/MetalGearSolid4GunsOfThePatriots the 4th game]] when Snake suppressed his nanomachines so they couldn't heal him.
* VideoGame/TheBannerSaga : The final boss [[spoiler:Bellower, leader of the ennemy]] was immortal, the only way to "kill" him was [[spoiler: To make him believe he was dead. Even then, he will wake up in a thousand year to understand he didn't die that day.]] Let's just say he will be pretty pissed off.
* The immortals of ''LostOdyssey'' are completely indestructible in the story -- but GameplayAndStorySegregation means they function like FromASingleCell-like immortality during gameplay (can be hurt and [[OnlyMostlyDead "killed"]] during gameplay, but revive on their own).
** To give you an idea how implacible the story considers them, at then end of the ActionPrologue, Kaim gets hit directly by a pyroclastic flow. When the duct clears, everything in a multi-mile radius is as dead as you'd expect. He's not even knocked off his feet.
* The Unbreakable Darkness of ''VideoGame/MagicalGirlLyricalNanohaAsPortable: The Gears of Destiny'', an EldritchAbomination that was sealed in the Book of Darkness. Despite looking like a little girl, she's older than the previously established immortals of the series. She's also unable to die [[DeathSeeker no matter how much she wants to]], a fact demonstrated when she takes the strongest attacks in the entire franchise without receiving a scratch even when she's at just a fraction of her full strength. The [[AudioAdaptation Sound Stages]] even hint that she's probably alive in the main continuity where her [[SealedEvilInACan can]] was completely destroyed without her awakening... [[{{Foreshadowing}} it's just that returning from complete disintegration may take 10 or more years]].
* [[WhoWantsToLiveForever Fujiwara no Mokou]] and [[LivingForeverIsAwesome Kaguya Houraisan]] from ''Videogame/{{Touhou}}'' are immortal in the truest sense. While it functions somewhat like FromASingleCell and mostly like ResurrectiveImmortality, they literally cannot die. Due to the laws of reality in Gensokyo when someone enters an area desegnated as the afterlife, where people can come and go, they count as dead. Mokou and Kaguya near literally run into a wall they cannot pass. Yuyuko has the power to cause anything to die at will. The two immortals are completely unaffected. They will probably exist til the end of time. Others ''could'' share in by temporarily killing either and devouring their liver, but few (even in Gensokyo) are mad enough to try the immortality the Hourai Elixir they drank brings. The way the Elixir works, even if you went back in time to kill them before they drank the elixir it wouldn't work. It's implied the Elixir was created by distilling Kaguya's power over eternity into a liquid, removing the users from the cycle of life and death completely, not just from when they drank it.
* The Nameless One from ''Videogame/PlanescapeTorment'' [[spoiler:had his mortality stripped from him]] and is therefore a true immortal in the exact literal sense. There are ways that will kill his body (thus, for all practical purposes of gameplay, kill him) due to ruining his HealingFactor (AndIMustScream scenarios, being killed by a God or god-like being like The Lady, cremation, dissolved in acid), but on a spiritual level he will never die: His spirit can never move on, he can never reach the afterlife, and [[spoiler:because the Grim Reaper essentially sees him as a blank in the books, someone else dies in his place every time he would die instead.]]
** It is stated that in addition to the Lady of Pain, [[spoiler:Lothar]] is one of the entities that can completely and irreversibly destroy The Nameless One.
* [[spoiler:God, the final boss]] in ''VideoGame/DuelSaviorDestiny'' is ageless and completely impossible to kill, though not impossible to damage. The damage just doesn't stick. After being beaten in a fight, he'll just stand back up again and keep going.
* ''VideoGame/GhostTrick'' features an odd form of this. [[spoiler:Having a Temsik meteor fragment embedded in one's body is as fatal as a meteor wound should be, but doesn't let the victim die. Instead the body is suspended at the moment of death, instantly regenerating any harm done to it. The kicker? This "caught between life and death" deal also applies to the person's soul, which can stick around and animate the body again, or freely leave it to perform whatever Ghost Tricks they were [[SuperPowerLottery lucky enough to end up with]].]]
* In ''VideoGame/InfinityBlade'', the Worker of Secrets is the only true immortal in the series. Even the fully-charged Infinity Blade cannot permanently kill him [[spoiler:since he wasn't stupid enough to create a weapon capable of killing himself.]] In the end [[spoiler:Siris uses the same technology that erased his memory when he was Ausar the Vile to erase the Worker's.]]
* In ''Videogame/CastlevaniaLordsOfShadow'', [[spoiler:Gabriel Belmont]] eventually becomes the immortal Dracula. [[spoiler:Since he's still God's chosen champion]], Dracula does not have the typical vampiric weakness to holy weapons, making him effectively invincible. The only thing that can truly kill him is the Vampire Killer Combat Cross [[spoiler:his former weapon]].
* In the ''VideoGame/WarioLand'' series, Wario cannot be killed by any means in ''VideoGame/WarioLandII'' and ''VideoGame/WarioLand3''. Burning into a pile of ashes just causes him to regenerate, and most enemy attacks revolve around inconveniencing him.

[[folder:Web Comics]]

* The golem girls in ''Webcomic/WapsiSquare'' have this kind of immortality.
* ''Webcomic/GunnerkriggCourt'': Jones has survived, in reverse chronological order: [[ a sword to the face]], [[ ground-zero of a SC50 bomb]], [[ a munitions factory explosion]], [[ a spear to the abdomen]], [[spoiler: [[ the burning of Rome]], [[ a barefoot walk across the Gobi desert]], [[ a bare-chested hunt with Cro-Magnon men]] (her technique is to literally grab the giant bull by the horns), [[ a nude hike across a glacier]] (frozen eyes? No problem), [[ waking up underwater]] after being buried in rock for 3 billion years, and [[ spending the first 2 billion taking a lava bath]] ]]. To drive this home, in a dispute with [[{{Psychopomp}} Ankou]] (who is basically TheGrimReaper) over who [[spoiler:Mort's soul]] belongs to, [[spoiler:the [[ third party]] goes with ''seniority'' and sides with Jones]]. She doesn't age, nor (apparently) [[spoiler: eat, sleep, breathe, expel wastes, emote, create, imagine, or remember anything prior to taking that lava bath (and she remembers everything since), so she doesn't even know ''what'' she is.]]
* ''Webcomic/{{Jix}}'': Kelelder the Planet Thief, regenerative type, he's been teleported into the sun twice and his spirit just went back to his ship and generated a new body.
* In ''Webcomic/CucumberQuest'', [[ the Nightmare Knight can't be killed.]] Only made SealedEvilInACan.
* Lord English of ''WebComic/{{Homestuck}}'' has "unconditional immortality" and on top of that, YouCantFightFate always works in his favor (since he is [[spoiler:a superpowered Lord of Time]]), so that even if someone went back in time to prevent his rise to power, that event would be instantly {{Ret Gone}}d. It has been hinted that there is ''one'' specific thing that can kill him, however.
** After being asked if Lord English was a [[Franchise/{{Ultima}} Lord British]] {{Expy}}, [[WordOfGod Andrew said]] [[ThrowItIn that he]] ''wasn't'' (instead just named that to keep the Felt's pool theme). The result? "[[AscendedFanon He's rumored]] [[ to be killable]] [[LordBritishPostulate only through a number of glitches and exploits in spacetime]]".
* In ''Webcomic/TheSilverEye'' Melete Dolan cursed herself to be eternal so she would't have any chance of being reunited with her husband in the afterlife. Although the full extent of her invunerability is unknown, she can heal herself unless kept in extreme pain, and even then, there is no evidence that her wounds would kill her.
* In ''Webcomic/GrrlPower'', there is a super code-named Achilles whose power is 'proper, aggravating invincibility'. He is completely and absolutely indestructible, withstanding things that destroy conventional matter on a subatomic scale, and has a measure of heightened strength since he doesn't have to worry about his tendons and bones failing under the strain. He is ''so'' invulnerable that not even ''time'' can harm him, [[TheAgeless making him look exactly like he did back when his powers kicked into gear]] -- nearly thirty years ago.
* The background information to ''Webcomic/TowerOfGod'' mentions how Zahard and his 10 Warriors got immortality granted by the [[CosmicEntity Guardian of the 100th floor of the Tower]]. Except for Bloomadder. He must regularly sacrifice his family to keep immortal.

[[folder:Web Original]]
* The [[NoNameGiven Narrator]] of [[ Immortality Blows]] has immortality "so perfect" that he/she [[ApocalypseHow survives the end of the world]]
* The character Anne Poole, from ''Literature/FineStructure'', is cursed with this form of immortality. She is indestructible and immortal, which becomes a problem near the beginning of the story when she's accidentally teleported into ''solid rock''. By the time they get to her, she's gone insane from deprivation. Of course, she eventually gets better, and she goes on to live tens of thousands of years longer; it's revealed that she actually goes through phases of insanity, as the human mind isn't meant to have that kind of continuity.
** From the woman herself:
-->''Sometimes the discovery becomes massive and everybody in the world finds out at once and I end up on a pedestal. Sometimes they make me their leader, sometimes they call me an abomination, sometimes I get arrested and studied, usually it's all of this at once. I've been everywhere. I've done everything, spoken every language, built a pyramid, survived re-entry. History goes in cycles. If you watch it for long enough you can see the tipping points coming and be there when they happen. I invented fire, the wheel, the electric motor, antibiotics, you name it, every era, every country. Fought in X number of wars. Once, I actually ruled the whole world.''
-->''I've walked on the Moon barefoot.''
* The Wiki/SCPFoundation:
** SCP-682 is described as a "Hard-to-Destroy Reptile".
*** It's a [[OmnicidalManiac homicidal]], [[HealingFactor regenerating]] dinosaur that [[AdaptiveAbility adapts]] to whatever you throw at it. They haven't tried things like nuclear bombs on it yet, because the last thing they need is a radioactive, red hot homicidal indestructible dinosaur. Between experiments, they keep 682 stored in a tank of concentrated acid, because while that won't ''kill'' it, not having a muscular structure will at least make it hard for it to cause any trouble. Though it still manages to break out of it occasionally.
*** It once fought a creature (created by the Foundation) with the sole descriptive factor of being able to kill 682 completely and utterly. [[BeyondTheImpossible 682 won.]] On other occasions, 682 has shown formidable resistance to being ''written out of reality itself'' and can operate in situations where the fundamental laws of physics are radically different.
*** Not entirely true. [[ It can be killed by drunk driving.]]
*** There are other complete immortals in the SCP holding cells, including the Demon Born of War, but 682 is the most famous. The site now disapproves of these sorts of SCP's being written, and having an SCP be absolutely immortal is an instant deletion. Able, 682, and several others continue to exist solely by virtue of the GrandfatherClause. The site's admins refer to this as the "Able Rule" - if your creation is more powerful than Able, it's toast.
** [[ SCP-014]] is immortal (as completely as Jones, above) because [[YourMindMakesItReal he believes he is]] -- he's also completely immobile because what he believes is that [[TakenForGranite he was cursed and turned into concrete.]]


[[folder:Western Animation]]
* In WesternAnimation/JackieChanAdventures, the Dog Talisman grants [[TheAgeless immortality and eternal youth]], while the Horse Talisman [[FromASingleCell grants]] [[HealingFactor healing/regeneration]] and apparently deals with pain. Whoever has the power of both is this trope.
* The ''WesternAnimation/JusticeLeague'' incarnation of Vandal Savage appears to be a complete immortal: He doesn't age and shrugs off practically all damage. During his three appearances he [[spoiler:goes down with an air-plane in the Atlantic Ocean]], [[spoiler:stands at ground zero for a ColonyDrop]], and finally [[spoiler:gets stuck on an irradiated Earth pushed out of its orbit that is inhospitable to human life]]. None of this seems to bother him, [[spoiler:although the latter version became RetGone after Superman [[SetRightWhatOnceWentWrong went back in time and stopped the cause of the disaster.]]]]
* In ''WesternAnimation/TheRealGhostbusters'', virtually all ghosts and other paranormal entities are this, as ectoplasm can not be destroyed. As such, the protagonists [[WeaponsThatSuck trap them]] and place them in the [[ContainmentField Containment Unit]] to dispose of them. The cartoon once in a while featured a few ghosts and demons get their Complete Immortality revoked in various, often spectacular ways, often through PhlebotinumBreakdown (both accidental and deliberate), getting their faces stuck in the barrel of the latest prototype BFG, or, getting eaten by [[AlwaysABiggerFish something big and unpleasant]].
** In one episode of the cartoon, a CorruptCorporateExecutive stole the designs of the proton throwers, and built his own robot to bust ghosts. The second half of the episode then shows exactly what happens when you don't trap the ghosts one busts. [[spoiler: They just come back angrier.]]
* In ''WesternAnimation/{{Gargoyles}}'', Demona and Macbeth are complete immortals thanks to the Weird Sisters' spell. Their lives are linked in such a way that as long as one lives, the other cannot die. Even getting a sword shoved into their gut is little more than a minor inconvenience from which they can quickly recover. Their aging is also halted. They can only die if they kill each other. Given that the two have grown to despise each other, they end up attempting to do just that every time they meet. Though Demona is stuck since she doesn't want to die yet, [[DeathSeeker while Macbeth does]].
* Klarion the Witch Boy in ''WesternAnimation/{{Young Justice}}'' is chaos personified and thus cannot be killed by any possible means. Though if his anchor to the physical world is broken (in the form of his cat Teekl), he will be sent back to his home dimension.
* In ''WesternAnimation/HulkAndTheAgentsOfSMASH'', The Collector has been shown to be one of these.
* WesternAnimation/SamuraiJack: Aku has never aged since he was born, and is immune to most attacks. The only thing that can harm him is the power of the Gods, as three destroyed the EldritchAbomination that spawned him, and Jack's sword was forged by them. In addition, the goddess from "Jack and the Gangsters" is powerful enough to defeat him, as are her elemental creatures.
* Bill from ''WesternAnimation/ItsSuchABeautifulDay'', should you believe the narrator at the end of the third chapter.
* In ''WesternAnimation/TheLegendOfKorra'', the Great Spirits of Light and Darkness, Raava and Vaatu, are both truly immortal. Even if one were to be physically destroyed, they would regenerate within their counterpart and emerge once more ten thousand years later. They fight an everlasting battle for dominance over the world, Raava for Light and Order, Vaatu for Darkness and Chaos.
* ''WesternAnimation/{{Archer}}'' reveals in "Drastic Voyage: Part II" that he believes himself to have this, which is weird considering he'd already [[BackFromTheDead died and come back once before.]]
