[[caption-width-right:286:Wolverine [[NightmareFuel recovers]] from his latest [[{{Pun}} face-off]].]]

->'''ComicBook/{{Wolverine}}:''' I've survived five different wars in my lifetime.\\
'''[[{{ComicBook/Watchmen}} Comedian]]:''' Yeah, that's really nothing to brag about when one of your main powers is ''not dying''.
-->-- ''WebVideo/ImAMarvelAndImADC'', "[[http://www.youtube.com/watch?v=k-om2kuKS24 Wolverine and Watchmen]]"

A character is hard to kill, not because he doesn't get hurt, but because he has the ability to rapidly recover from serious damage. Although it depends on how fast he can heal and how much of a [[ChunkySalsaRule beating]] his body can take, a character with healing factor will bounce back from severe injuries that other beings can't, often with no scars or medical treatment.

Slightly more plausible than being SuperTough or {{Nigh Invulnerab|ility}}le, as it is a souped-up version of a power certain real life forms possess. When this ability is powerful enough (such as regenerating from being reduced to almost nothing), it actually becomes a form of NighInvulnerability, however. Rarely will a character need to worry about infection, as [[RequiredSecondaryPowers a super immune system]] is most often packaged in, but they may need to worry about setting broken bones.

Really powerful characters will be able to regenerate lost body parts. [[ComicBook/XMen Ridiculously powerful regenerators]] may be able to recover FromASingleCell in a stain on the floor. Most often, [[ChunkySalsaRule loss of the head or brain injury]] is [[DeaderThanDead the only permanent damage]], and even then they may come back just missing some memories or with an altered personality. Sometimes they appear to be dead for brief periods, but that's just the regeneration [[BackFromTheDead taking a while to deal with unusually severe damage]].

On the downside, extreme regeneration often leads to the character getting targeted by TheWorfBarrage so often that people go "GoodThingYouCanHeal" because their ImmortalLifeIsCheap. Also, regenerators are often more MadeOfPlasticine than the rest of the show's cast.

Note that if any real-world life form were able to recover this fast, they'd need a reserve of raw organic material to work from, and afterwards would be very hungry. The only way to justify always repairing [[ShapeShifterBaggage the exact amount of flesh damaged]] is if it uses the actual damaged flesh to do it. Writers who acknowledge this often at least have their regenerator out of commission for some time, resting and feeding... or [[AppendageAssimilation harvesting limbs]]. The effect may be compared to the rapid cell growth, differentiation and self-organization of human embryonic development if the writer is interested in [[MohsScaleOfSciFiHardness any degree of scientific plausibility]], but most don't bother with even that much HandWave; they just have the wounds close up and new tissues and organs appear. Depending on the strength of the regenerator, they may also be a practical PerpetualMotionMonster, able to go for months or years without food and water since their healing factor keeps their body alive... though this sort of ImmortalityHurts.

Reptilian characters, taking a cue from real-world lizards that can shed and re-grow their tails, are likely to possess at least a minor form of this. [[note]]These lizards suppress their immune system to allow their stem cells to respecialize, which would be very, very bad in a human and is why we can't do it.[[/note]] Dragons, werewolves, and vampires [[OurMonstersAreDifferent sometimes]] have it as well. Other ShapeShifting characters may have this packaged in with their powers, though it's often described as returning to their "default" form rather than regenerating. {{Nanomachines}} are a common justification for an acquired power by otherwise human characters in a [[CyberPunk technological setting]].

If regenerators have an AchillesHeel, it's most often a nasty one: either suffocation, decapitation, poison, gas, [[KillItWithFire fire]], ice, or acid. Other times, the weakness is similar to CloneDegeneration; each re-growth results in HarmfulHealing and increasingly damaged appendages/organs/[[CastFromLifespan shorter lifespan]].

An in-universe, as opposed to plot-based, version of HollywoodHealing. Doing this to others is HealingHands or using a HealingPotion.

If a character can be blown to bits and reform you could be looking at PullingThemselvesTogether. If it happens offscreen, this may be the explanation for an IronButtMonkey. If this appears in a video game without an [[JustifiedTrope in-story]] [[HandWave explanation]], it's RegeneratingHealth.

Also, it's more properly called an ''Accelerated'' Healing Factor; "Healing Factor" simply refers to how quickly you heal - normal humans, for instance, have their own healing factor: a normal one. This is in fact what it was originally called in comic books and elsewhere; "Healing Factor" emerged because it's, well, shorter.

Contrasts WoundThatWillNotHeal.



[[folder:Anime & Manga]]
* Both Yukiko and Liselotte Werckmeister from ''VisualNovel/ElevenEyes'' share the same immortality with rapid healing factor and undying. It is revealed that the Voidstone is the source of the immortality and separating it from the host will disable that immortality.
* Chirico Cuvie from ''Anime/ArmoredTrooperVOTOMS'' is called an "abnormal survivor," and has the capability to not only survive normally fatal physical injuries and illnesses, but to resist damage from certain types of injury, such as being burned alive by mecha fuel. However, as a negative side effect of this, he suffers extreme mental stress from all of the fatal injuries he has taken, to the point of being more or less outwardly emotionless. His early memories include being burned alive and shot through the heart.
* Koro-sensei, the VillainProtagonist of ''Manga/AssassinationClassroom'', can completely regenerate his tentacles and skin within seconds of having them sliced, melted, or blown off. It's eventually revealed that his top speed decreases by about 20% for every tentacle regenerated in succession.
* In ''Manga/AttackOnTitan'', the Titans are extremely fragile and relatively light despite their size. To make up for that, they have an extremely potent healing factor and feel almost no pain. They can recover from any injury as long as the napes of their necks aren't destroyed. [[spoiler: Titan Shifters also possess this ability, whether in human form or transformed into their Titans. Eren has regrown missing limbs and a tooth thanks to his powers. Likewise, Bertolt survives getting a SlashedThroat that ''should'' have been fatal and is barely slowed down. Reiner took this UpToEleven when he survived his head (his human head, not his Titan head) getting blown up with explosives by distributing his consciousness throughout his nervous system while his brain regenerates. Bertolt confirms that this is an ability all Shifters possess, but it's viewed as a last resort and because it can lead various kinds of brain damage (when Reiner recovered he was severely disoriented and had lost several hours of memeory)]]
* Immortals in ''LightNovel/{{Baccano}}'' get this standard with their {{immortality}}. They also avert the [[ShapeShifterBaggage Regenerative Baggage]] issue by using the damaged or spilled flesh and blood to patch up the wounds. Yes, even if their remains are splattered across the room, thrown off a speeding train, or (in the novels) [[KillItWithFire burned into smoke]]. A special version of the elixir was made by Szilard and given to Dallas and his cronies which gives them just the healing factor but they still age.
** Usage of this ability varies. One immortal escapes from ropes by tossing himself into a lit fireplace and crawling out once they're burned away. Another... cuts himself at parties so that he can impress his friends by how he can bleed in reverse.
* [[OurVampiresAreDifferent Mostly human]] protagonist Araragi Koyomi from ''LightNovel/{{Bakemonogatari}}'' can survive surprising amounts of punishment up to and including [[spoiler:Getting his heart torn out of his chest]]. Vampire's healing factor is explicitly weakened by [[WeakSauceWeakness poison]] but he's usually up and running by next morning.
* The Manga/BirdMen's power allow them to survive many injuries. Kamoda's dust allegies are gone, Eishi's eyesight is improved after getting the power, and is no longer required to wear glasses.
%%* Manji from ''Manga/BladeOfTheImmortal''
* Killy from ''Manga/{{Blame}}'' has a very slow-acting Healing Factor. He can apparently recover from any damage, but it takes years, or even decades. Severed limbs take less time to reattach, which is fairly necessary considering [[{{BFG}} the]] [[WaveMotionGun weapon]] [[HandCannon he]] [[BlownAcrossTheRoom uses]].
* ''Manga/{{Bleach}}'':
** It is actually an ability of many hollows to self-regenerate. Ulquiorra mentions that most of the Arrancar gave up this ability to become more powerful.
** Aizen has this as well in his Butterfly form. Case in point: [[spoiler:he survived Ichigo's ultimate attack]].
** Similarly, the Vandenreich give us [[spoiler: Giselle Gewelle]] and apparently [[spoiler: Askin Nakk Le Vaar]]. In the case of the first, [[spoiler: she]]'s able to easily survive [[spoiler: being nearly [[HalfTheManHeUsedToBe cut in half]]]]. Later, when [[spoiler: Ichigo]] arrives and tosses [[spoiler: her]] and other characters into a bunch of destroyed buildings, the impact breaks [[spoiler: Giselle]]'s neck... but not only [[spoiler: she]] survives to that, but [[spoiler: she]] then puts [[spoiler: her]] own neck back in place like it's nothing. ([[spoiler: This doesn't make Giselle ''absolutely'' invulnerable, however; after being stabbed through the chest, she actually needs to consume someone else's flesh and blood to heal herself]]). The second [[spoiler: has the power of surviving every time he should be close to death -- which might have allowed him to, alongside Ishida, ''survive ThePurge from Yhwach'']].
* Rin from ''Manga/BlueExorcist'' heals from wounds pretty fast. Like, getting stabbed in the stomach only for it to heal in mere minutes? Arthur even [[spoiler: cut off his foot, since he knew it would grow back sooner or later]].
* The monomakia from ''Anime/BrigadoonMarinAndMelan'' heal rapidly, especially if they return to their ampules. The monomakia Cosmos can apparently confer a lesser degree of healing factor on its user, too.
* ''Manga/BusouRenkin'' - Ikusabe, one of the alchemic warriors employed by the Regiment. His Busou Renkin, Gekisen, not only arms him with a triple-bladed spear, but it also concedes him and his weapon regenerative abilities, all the way from the atoms. He manages to regenerate his body completely even after Papillon blows it up completely!
* In ''LightNovel/ACertainMagicalIndex'':
** Tsuchimikado's esper ability is "Auto Regeneration", basically accelerated healing. He's only a Level 0, though, so it isn't accelerated by all that much.
** Every time Touma loses his right arm, it can be seamlessly reattached or grow back if the arm is destroyed. Any injuries to other parts of his body don't heal as fast as his arm, often requiring him to spend time in the hospital, but they do heal faster than normal.
** Another example, creatures made of AIM demonstrate the ability to rapidly heal any damage done to their physical body; the only way to kill them is to destroy a prism-shaped "core" somewhere within them.
** Othinus has an extremely powerful one due to being a goddess. She [[DeliberateInjuryGambit fires a massive arrow through her own torso so Touma won't see it coming]]. When he looks up, the wound is already gone.
* In ''Manga/{{Claymore}}'', Priscilla has an extreme form of the healing factor that takes it to the next dimension. To be specific, Dae speculate it is an embodiment of Priscilla's hatred boiling over from inside, leading Rubel to ask if he is saying it is '''[[ThePowerOfCreation creation]]'''. In short, a form of the healing factor residing in the domain of gods.
* C.C. from ''Anime/CodeGeass'', who can recover from fatal injuries (such as a bullet to the brain or heart) in a matter of minutes. A few episodes imply that she might be near Wolverine in terms of regeneration: [[spoiler:Her former partner Mao intended to cut her into pieces so he could ship her to Australia in luggage, and fully expected her to survive. In the season finale, her current partner Lelouch witnesses her tormented memories, including being burned at the stake, the Iron Maiden, and apparently being guillotined. The first season also ends with her trapped at the bottom of the ocean in a HumongousMecha, meaning she had to purge the cockpit and die at least twice due to pressure and drowning before she floated to the surface; WordOfGod confirmed this because there was no way they would get away with showing anything that gruesome on television]]. And for all this, the only mark she bears is a very deliberate-looking scar under her left breast.
** In the audio commentary, when the staff and cast discuss C.C.'s powers, voice actress Creator/{{Yukana}} jokingly suggests probably the cutest version of a Healing Factor ever: that when C.C. is killed, her body breaks apart into several miniature C.C.s that run together to re-form her original body
* ''Manga/CorpsePrincess'' in the show of the same name normally heal faster than humans, and can regenerate limbs given enough time. They can also have most wounds healed instantaneously by their contracted monk.
* [[spoiler: Princess Ixquic]] from ''Manga/{{Cyborg 009}}''. [[spoiler: Then it's subverted, since she's a RobotGirl.]]
* ''Manga/DGrayMan'':
** Kanda has accelerated healing, but at the cost of some of his life.
** Also Road, who can't be killed unless you know her "true form".
** And Krory, who can heal himself by drinking Akuma's blood.
** Taken UpToEleven in the Alma arc, in which both Kanda and Alma come back from [[spoiler: being blown up. Alma was the bomb]]. Subverted in that [[spoiler: Alma dies soon after and Kanda's healing factor seems to have run out]].
* In ''LightNovel/DateALive'', Kotori and Shido have this, but it only seems to activate when they are dealt life-threatening wounds. Once this happens, blue flames appear from ''every'' injury they have and then they all heal.
* In ''LightNovel/DemonKingDaimao'', Sai gets an arm chopped off. The stump sprouts a new one, out of blood, which regenerates back to a regular arm in seconds.
* Kyouya from ''Manga/{{Diabolo}}'', despite his terminal illness, claims to heal in his sleep (and considering after a night's rest some scratches on his face disappeared, this may not have been a bluff).
* In ''Manga/DragonBall'', Namekians like Piccolo regenerate as long as their vital organs are intact. The later villains in ''Z'' have even greater regeneration abilities: Cell can regenerate FromASingleCell thanks to [[LEGOGenetics having]] both Piccolo's regeneration and Freeza's [[OnlyAFleshWound ridiculous durability]], while Majin Buu can regenerate after ''being reduced to vapour'' (due to being a very ancient being of magic.) In fact, regenerators like Cell and Buu get maimed so often that it's pretty blatant that the creators are just looking for opportunities to show off their self-healing abilities.
* In ''LightNovel/{{Durarara}}'', [[HalfHumanHybrid Quarter]]-[[HeadlessHorseman Dullahan]] [[spoiler:Ruri Hirijibe]] has this ability. A comment made by [[BackAlleyDoctor Shinra]] while treating her wounds suggests that not only does (the entirely human. [[WildMassGuessing Supposedly]]) [[CharlesAtlasSuperPower Shizuo Heiwajima]] have this as well, but that his is ''greater''. If nothing else, it would explain how he's [[HollywoodHealing recovered completely from things like shattering his spine and pelvis]] or [[spoiler:getting shot]].
* ''Manga/FrankenFran'':
** Chapter 3 is the story of a girl with a Healing Factor that reached BodyHorror levels. See, not only does it replace lost arms and legs, but it keeps on creating new body parts even when she's perfectly healthy. The end result is a body with multiple faces, organs, limbs, and torsos growing out of it at once. Fortunately for her, Fran manages to keep it in check, and cure the girl; she had to remove some of her actual limbs in the process, but the girl ''grew them back almost immediately''. Fran believes that this spectacular recovery was made possible thanks to the girl's incredible will to live.
** In Chapter 28, a man on death row survives and recovers from all of the methods of execution he's put through. After ruling out all other possible explanations, Fran comes to the conclusion that the guy is just BornLucky.
* The [[ArtificialHuman Homunculi]] from ''Manga/FullmetalAlchemist'' all have this power. The ShapeshifterBaggage is somewhat justified by having the Homunculi powered by a Philosopher's Stone, which converts energy into matter. When their stone runs out of juice, the Homunculi lose their powers & have to get it recharged (or run the risk of becoming DeaderThanDead).
* ''Anime/GunXSword'' - This is one of the perks of being linked to one of the Original Seven armors (mechs). Unfortunately, the symbiotic link also means that riders need their armor to live (at least if they have had reconstructive surgery).
* One of the "signature" abilities of the Deadman soldiers in ''VideoGame/{{Gungrave}}'' is the ability to regenerate/near-instantly revive from almost all injuries sustained. Beyond the Grave, the heroic Deadman of the series, has this ability because of the technology used to reanimate him and other Deadmen. Grave's weakness? His healing is powered by full-body transfusions of his (rare?) blood type. Lack of blood for a prolonged period of time results in him decomposing and slowly reverting back to true death.
* The Guyvers from ''[[Manga/{{Guyver}} Biobooster Armour Guyver]]'' can regenerate their entire bodies if destroyed, so long as the control medal on their foreheads is not damaged. At one point, lead character Sho contemplates being a clone since his original body was killed.
** In addition, Aptom develops a massively potent regeneration ability, still limited to available biomatter unlike the Guyvers, which he uses to great effect by splitting up in to clones and using one as a distraction.
** Finally, any of the monsters created by Chronos could have damage regenerated by spending some time in a giant test tube.
* In the third episode of ''Anime/HareGuu'', Guu regenerated her arm. After chopping it up and ''eating it.''
* Most of the major characters of ''Manga/{{Hellsing}}'', and the Nazi vampire {{mooks}} that show up later in the manga, have impressive regeneration abilities; Alexander Anderson, for example, can take several headshots in rapid succession and keep fighting. Every single one of them is put to shame by Alucard, though, who ''allows'' himself to be near-liquified at the beginning of several fights before putting himself back together just to completely demoralize his opponents before brutally killing them.
** Schrodinger probably takes the cake; it's implied that his ill-defined ability to be everywhere and nowhere lets him ignore any injury, and he shrugs off having his head splattered by an extra-large anti-vampire bullet.
** Schrodinger's case is more a ''rejection of state'' than actual healing, of the '[[{{Retcon}} he was never there in the first place]]' variety.
* ''Manga/InuYasha'':
** {{Youkai}} always heal much quicker than humans do and [[AloofBigBrother Sesshoumaru]] is tougher than most. At one point, he gets his [[HandicappedBadass one single arm]] torn to shreds resulting in him having to be [[BadassInDistress rescued]] by [[TheHero Inuyasha]]. This results in the following exchange, which angers Sesshoumaru so much that he actually earns a [[UpToEleven regeneration upgrade]] that, by the end of the fight, [[spoiler: enables him to not just regenerate the damage to his right arm, but to also eventually ''[[SerialEscalation regenerate his missing left arm]]'']].
-->'''Inuyasha (to Sesshoumaru):''' 'You just stay back! This is no place for an injured person!'
-->'''Jaken:''' 'What's that?! Just whose fault do you think it is that it came to this?! It's solely because [[spoiler: Meidou Zangetsuha was turned over to someone like you]] that Sesshoumaru-sama has...'
-->'''Inuyasha:''' 'Shut up!' ''Thinks'': 'I know that. [[spoiler: If he'd at least had a weapon,]] Sesshoumaru wouldn't have been wounded to this extent...'
-->'''Sesshoumaru (to Magatsuhi):''' 'Hmph. You despicable creature. Making me receive pity from the likes of a [[HalfHumanHybrid hanyou]]...'
-->'''Jaken:''' 'Oooh! He closed his wounds with [[{{Determinator}} pure fighting spirit]]! Nothing less from Sesshoumaru-sama!'
** Then, there's Naraku. Being cut to bits is only a minor inconvenience to him.
** Kikyou is capable of healing herself using the souls that she has collected to sustain her fake body. After being beat up particularly bad (which happens a lot, she has fallen from many a cliffs), she retreats into her barrier to recover and collect more souls for a while before showing up again, fine and dandy. The power of the soul in question seems to determine how much she is capable of healing and one particularly powerful one allows her to recover from wounds that threatened to destroy her body. Considering that many of the souls she collects likely belong to no name and weak village girls, it makes sense why this ability probably wouldn't be capable of doing all that much normally.
* ''LightNovel/IsThisAZombie'' Ayumu will heal from anything. It helps that he's already dead but he still feels pain and can be injured. When he leaps off a building holding a bomb the girls in his harem have to collect all his body parts and reattach them before he heals.
* In ''Manga/JoJosBizarreAdventure'', [[OurVampiresAreDifferent vampires]] and the [[HumanoidAbomination Pillar Men]] have this, making them immortal. The only way to kill them is with sunlight or [[KiManipulation the Ripple]].
** Okuyasu's father in Part 4 also has this. In his case, it's an example of BlessedWithSuck as he is extremely deformed and has mentally regressed into an animal due to being infused with Dio's vampiric cells and his son, Keicho, wants to put him out of his misery.
* One of the abilities of Life Fiber hybrids in ''Anime/KillLaKill'', including [[spoiler:protagonist Ryuko]].
* In the first chapter of ''Manga/KobayashiSanChiNoMaidDragon'', Tooru serves Kobayashi a grilled piece of her tail then grows it back.
* In ''Manga/LoveHina'', Keitaro's immortality is expressed as being able to completely heal from the worst [[MegatonPunch Megaton Punches]] and landings from said punches within a few panels. This is averted only once, when he gets his leg broken; that takes several chapters to heal, and [[UnwantedHarem the Hinata girls]] are amazed that it actually happened. Oh, and the reason? The ''giant'' decorative thing on the top of the university hall fall on him. And this only happened because someone [[TemptingFate said he used up all his luck]].
* ''Franchise/LyricalNanoha''
** The [[RidiculouslyHumanRobots Wolkenritter]] of ''Anime/MagicalGirlLyricalNanoha''. They may have lost the [[BackFromTheDead Rejuvenation Program]], but they still have a healing factor that lets them recover a lot faster than a normal human. However, this has been getting weaker as time goes by, though thankfully for Vita, not so much that [[spoiler: [[NormallyIWouldBeDeadNow her getting impaled in the chest]]]] could take her out permanently.
** In ''Manga/MagicalRecordLyricalNanohaForce'', and we're introduced to the Huckubein, who can regenerate even better than the Wolkenritter. [[DualWielding Cypha]] proves this by [[OnlyAFleshWound regrowing an arm]] that Signum cut off. Oh, and they're also [[MadeOfIron pretty darn tough too.]]
** ''Force'' also revealed that Hayate gained some of the Wolkenritter's healing factor when she [[spoiler:[[SuperEmpowering absorbed the]] [[LostTechnology Tome of the Night Sky]]]] and became the "[[RedBaron Walking Lost Logia]]". Not enough to survive a mortal blow, but enough to recover from wounds faster than usual.
* ''Manga/MahouSenseiNegima'':
** Kotaro has one as part of his ultimate demon form, [[spoiler: and it's pretty freaking good, considering he survived getting impaled in the chest by a bunch of Rakan's giants swords]].
** Negi can reform severed limbs in his lightning mode. This is because he ''turns his body into lightning'', and therefore can't be permanently injured by physical attacks. [[spoiler:Naturally, he promptly runs into an opponent who can bypass that protection...]]
** Evangeline can easily heal things like being impaled, losing a limb or [[ArsonMurderAndJaywalking having her hair cut]] in a matter of seconds.
* The Immortals from the ''Manga/MermaidSaga'' can regenerate from any wound, naturally, except burning to ash or having their heads completely severed.
* This is Rin Asougi's only power in ''Anime/{{Mnemosyne}}''. Unfortunately for her, this means she loses fights quite regularly, with fatal results. Seeing as how she can only permanently die from being devoured alive by a specific monster or having her 'time spore' pulled out by a specific person, this isn't quite BlessedWithSuck.
* Subverted in some aspects in ''Manga/{{Naruto}}'': Tsunade and Naruto can regenerate from grievous injuries very quickly, but they do so via rapid cellular growth, which ages their bodies prematurely [[CastFromLifespan and shortens their lifespans]] ([[http://en.wikipedia.org/wiki/Hayflick_limit which actually happens]]). Also, Naruto tends to pass out and become famished regenerating anything more than minor injuries. "No matter what the injury is, one night of sleep has always been enough." This isn't as serious a problem for Naruto since he is descended from a LongLived clan.
** Played straighter with Orochimaru though, who has survived being cut in half amongst other things and shrugged it off. He can even shed his skin which regenerates himself, giving the appearance of vomiting out a fresh body. He also can soak up an insane amount of blunt force trauma, far more than any normal character in the story.
*** He can do so without fear of shortening his lifespan because he regularly commits GrandTheftMe on others. It does however mean he burns through weaker bodies in just the three years he has before his transfer form can survive another transplant.
** Tobi and [[spoiler:Madara]] are able to pull this off thanks to [[BadassTransplant cloned flesh grafts from Hashirama]]. Tobi has sacrificed his right arm on a few occasions while [[spoiler:Madara]] recovered from losing an arm and having most of his chest cavity pulped.
** One of the greatest dangers of the Edo Tensei is that physical damage will only slow them temporarily. They will repair any damage, even being completely torn apart, unless they can be sealed before regaining mobility.
** Karin, [[spoiler: another Uzumaki,]] has a healing factor boosted by Orochimaru's experiments to the point where she can shrug off impalement. And she can heal others by letting them bite her and feed off her chakra.
* Berserk Evangelions from ''Anime/NeonGenesisEvangelion'' have this ability, ranging from regrowing shattered bone to [[spoiler:manifesting whole limbs out of angelic flesh or its own AT Field]]. [[EldritchAbomination Angels]] have his by default, as all of them have S2 organs and couldn't operate alone without support units.
* Both averted and played straight in ''Manga/OnePiece''. Characters who have eaten [[SuperpowerLottery Logia Devil Fruits]] ''appear'' to have healing factors. But in reality, they can just put themselves back together if they get cut while using their abilities. If they actually get injured, then they can't heal themselves simply by changing into whatever element they have. But then there's Marco, First Division commander of the [[BadassCrew Whitebeard Pirates]], who actually does have a healing factor, thanks to eating a Mythical Zoan Fruit that lets him change into a phoenix.
** Arlong is a more specific example in that he can regrow his teeth almost immediately, to the point that he rips out two whole sets himself to use as impromptu weapons.
* This ability is one of the signs that [[TheChosenMany the Baskervilles]] from ''Manga/PandoraHearts'' are NotQuiteHuman: they can recover very quickly and survive any attack from ordinary humans, including a bullet to the head. Only a select few [[OurMonstersAreDifferent Chains]] (and their [[DealWithTheDevil contractors]]) can kill a Baskerville, most notably [[TheMadHatter Mad Hatter]] and [[HairRaisingHare the Blood-Stained Black Rabbit]].
* Deoxys in the [[Anime/PokemonDestinyDeoxys seventh]] ''Anime/{{Pokemon}}'' movie is depicted regenerating a vaporized limb. In fact it can [[FromASingleCell regenerate its entire body as long its crystal core is intact]].
* In ''Manga/PopcornAvatar'', this is one of Ryuudou Taiga's abilities as his sister's avatar.
* ''Anime/PuellaMagiMadokaMagica'': Sayaka gets this, as a result of her wish involving healing. It's indicated that they can all do this with healing magic, but Sayaka is probably the best at it.
* Taken UpToEleven with Saffron in ''Manga/RanmaOneHalf''. Any wound inflicted on him, in any way, is healed within seconds (or sooner) through the power of his own flame. When being frozen solid and ''shattered'' forced a massive regeneration, but still failed to kill him, you know you're in the big leagues of GoodThingYouCanHeal.
* Loosely implied to be a [[OurVampiresAreDifferent vampire's]] source of immortality in ''Manga/RosarioToVampire''. Their blood has a powerful regenerative effect on anyone, which Tsukune is quick to demonstrate once this is introduced. [[spoiler: To date, a quick infusion of vampire blood or the activation of the blood already present inside of him has saved him from: being burned alive, slashed through the ''heart'', having his neck snapped ''twice'', taking two fatal slashes to the torso, having the entire left side of his body crushed, taking an absurdly long beating and a giant scythe-like appendage to the chest immediately after, and that's all in the first season.]]
** Akasha Bloodriver has a very powerful healing factor that can cover up even the most fatal of injures. [[spoiler:Even cutting her in half won't be enough to kill her.]]
* The Wu from the manga and anime ''Manga/SazanEyes'' are people who have had their souls extracted by an immortal Sanjiyan Unkara and kept within the Sanjiyan. As long as the Sanjiyan lives, the Wu cannot be killed or destroyed -- by ''anything.'' Their healing factor is so great that main character Yakumo once regenerated from being ''chewed into tiny scraps'' by a giant demon in a matter of minutes. The one time where an Wu was dismembered without re-attaching it instantly after the fight, the arm was kept in an sealed container. However, that might have been just to keep the arm from moving; after all, Wus can still move their body parts even if they're cut off. When the container shattered and (more important) the seal on it, Yakumo's arm instantly started to grow back, informing him something was going wrong. And in the manga, he almost regularly loses his limbs and regows them (often resulting in him losing his combat gloves). -> Note: Wu go into "super" mode when their linked Sanjiyan is in danger, and this includes this healing factor becoming many times more powerful.
* In ''LightNovel/{{Slayers}}'', trolls have such fast regeneration abilities that they are nearly impossible to kill. The main character, Lina Inverse, solves this issue by [[spoiler:casting a magic-reversal spell on all the trolls so that even the [[ScratchDamage tiniest scratch]] results in [[HoistByHisOwnPetard nearly instant death-by-implosion]]]].
* ''Manga/SoulEater'' has a couple of examples. People infected the with Black Blood have been shown to heal quickly from those injuries their nigh-invulnerability doesn't protect them from. Werewolf Free thinks nothing of getting stabbed because he can easily heal. Lastly, Kid gains this at one point in the manga, being able to [[PullingThemselvesTogether re-attach]] a limb.
* Yuki Nagato from ''LightNovel/SuzumiyaHaruhi'' is able to regenerate using her MagicFromTechnology, apart from being seemingly unaffected by physical injuries. The limits are unknown, but it does happen in an instant.
* ''Anime/TengenToppaGurrenLagann'' - Viral undergoes some form of bioengineering that causes him to stop aging and gives him this, making him effectively immortal.
** This was given to him by Lordgenome, who achieves immortality by putting cells into biological stasis. He applied this to himself [[spoiler:hundreds, possibly thousands of years before episode 1 takes place]].
* In ''Anime/TigerAndBunny'', one of the less utilized advantages of [[spoiler:Kotetsu's [[HourOfPower Hundred Power]]]] - one that doesn't see use until the thirteenth episode - is the ability to accelerate the speed of his healing by a hundredfold. Unfortunately, this only means that (at the absolute most) he can give himself less than eight-and-a-half hours' worth of concentrated healing, which, as any doctor will tell you, is barely enough time to sort out the ''cosmetic'' damage, let alone the serious stuff. Though he'd be able to cram almost a weeks worth of recovery in a single day if he'd use it after every hour or so (more if he'd be willing to forego sleep).
* In ''Manga/{{Tokko}}'', a healing factor is one of the powers gained by people with [[PowersViaPossession phantoms]] living inside them.
* The titular [[OurGhoulsAreCreepier Ghouls]] in ''Manga/TokyoGhoul'' can regenerate as part of their standard set of superhuman abilities. This ability varies wildly between individuals, with the [[CombatTentacles Rinkaku]] types typically having the strongest regenerative abilities. Protagonist Ken Kaneki is noted to have inherited powerful regenerative abilities, which allows him to do things like regrow severed fingers or even survive being [[spoiler: stabbed through the skull ''twice'']]. The most extreme examples in the series are horrific beings capable of literally PullingThemselvesTogether, treating decapitation or being sliced in half as a minor annoyance at most. While a weak ghoul can be killed fairly easily, the strongest are almost impossible to kill due to their powerful regeneration.
* Quon of ''Anime/TowaNoQuon'' has this as one of his abilities.
* In the ''Manga/{{Trigun}}'' manga, members of the Eye of Michael can have a really strong healing factor capable of regenerating the loss of a large percentage of the body within minutes by drinking out of special vials. This leads to their fights being some of the most prolonged and grisly in the series. This ability comes at a cost of being CastFromLifespan.
* Abel from ''LightNovel/TrinityBlood'' has been shown regenerating a lost arm (from the leftover pool of blood) after it was blown off.
* Inugami Akira of ''Manga/WolfGuyWolfenCrest'' has this on account of being a [[OurWerewolvesAreDifferent werewolf]]. During the full moon, he's [[NighInvulnerability night invulnerable]].
* ''Manga/YuYuHakusho''. The older Toguro brother, who can both regenerate and restructure his body at will, and will apparently survive any and all injuries as long as [[FromASingleCell even a single cell of him]] is still alive. [[spoiler: So Kurama ultimately traps him in a FateWorseThanDeath.]] The younger brother also has a healing factor, though not as strong as Elder Toguro's, as shown when [[spoiler: Genkai blows a large hole in him with the Spirit Wave]]. He simply doesn't have to use it as much since he's also MadeOfIron.

[[folder:Comic Books]]
* ''Comicbook/XMen'':
** ComicBook/{{Wolverine}} is the iconic SuperHero example. This has been subject to extreme PowerCreepPowerSeep; he went from "very tough, but can be killed by a single lucky shot from a HumongousMecha" to "survive being at ground zero of a nuke". (He was also once regrown from a single droplet of blood that fell on a powerful [[MacGuffin Ancient Artifact]] once, but that was more a demonstration of the artifact's power than his own, and [[OrWasItADream may have been hallucinatory]] anyway).\\
An arc in his main book was written to tone this down -- by the same writer who had written one of the more ridiculous examples, ironically enough.It exemplifies VoodooShark - he could ''battle the Angel of Death'' if ever he dies in order to return to life, having beaten him before, but apparently can no longer do this.\\
There's also Wolverine's OppositeSexClone ComicBook/{{X 23}}, who has all of Wolverine's powers. Though the exact nature of her healing factor outside of Limbo has yet to be determined. It apparently has [[http://scans-daily.dreamwidth.org/677992.html some limit]] (then again, she ''did'' take a direct hit from ''Nimrod''). Wolverine's son {{ComicBook/Daken}} also inherited his father's healing factor.\\
Finally, Wolverine's arch-enemy ComicBook/{{Sabretooth}} had virtually the same power-set, including the healing factor. But all that was cut to an abrupt end. Thanks to Wolvie's anti-healing [[InfinityPlusOneSword katana]] forged from the [[TheDarkSide dark area]] of his soul. It was later revealed that Creed wasn't actually dead, [[SarcasmMode what a shock]].
** Marvel seems to have made it a point to establish that all of the above can die from drowning and all but Logan (due to his adamantium skeleton) can die from beheading.
** Due to the nature of most children's shows, this can't be shown that effectively. The 90's ''WesternAnimation/XMen'' animated show tries to, but it amounts to them needing less rest than everyone else; it's best shown on TV in ''WesternAnimation/XMenEvolution'' when Wolverine is shown to have broken his legs from a helicopter jump, and later on in Season 4 when he falls out a plane.
** Mr Sinister has a healing factor that puts the two of them to shame; he can recover from massive physical wounds, up to and including having his entire chest blown out, and DependingOnTheWriter he can even recover FromASingleCell, or at least from having his entire body reduced to liquid. He is essentially the T-1000 (though he predates him), and since he seemingly has no blood, BloodlessCarnage is in effect and his factor ''was'' portrayed in the animated series fairly blatantly.
** ComicBook/{{Apocalypse}}, likewise, has a great healing factor, though not quite as broken as Sinister's. It appears to be an extension of his Celestial tech PoweredArmor and VoluntaryShapeshifting, as he more or less appears to close any wound at will--which means, he consciously chooses to heal them, so it's not really a separate power and if he left them the wounds would probably heal at a normal rate, but with his powers he can do it in seconds. In general, this is limited to superficial-to-moderate injuries--he probably can't recover from, say, dismemberment--but things that would kill anyone else he can shrug off with a laugh. The fact that he also has NighInvulnerability combined with ComboPlatterPowers (including very strong personal {{Force Field}}s) means that doing him harm in the first place is a challenge in itself. He also pulls a GrandTheftMe every now and then, targeting especially powerful mutants when he can (regardless, the new host inherits his old powers), and can recover from near-death either by that or by draining energy from any minions he has infused with his technology.
* SelfDemonstrating/{{Lobo}} from Creator/DCComics has an absurdly over-the-top one, as he is partly a Wolverine parody. Plus, neither Heaven nor Hell want him.
** This is taken to such ridiculous extremes that at one point, one of his powers was that a single drop of his blood will grow into another Lobo.
*** In one story, Lobo was "killed" by having a very special bomb shoved down his throat. He exploded in a spray of crimson... only for EACH drop of blob to grow into a Lobo clone in a matter of seconds. The group of Lobos brutally murder the aggressor.... and then turn on each other, specifically murdering each other in bloodless ways, until only one remains. He announces that he is the true Lobo, and then goes off doing Lobo type things. It's implied that this happens regularly.
* The ComicBook/MartianManhunter can regenerate from almost any injury. He once even grew his whole body from a severed arm.
* ''ComicBook/PainkillerJane'' has this power.
* The ComicBook/IncredibleHulk has been at various times shown to have a healing factor that makes Wolverine's pale in comparison at times. (Including having all his skin ripped off and regrown in seconds--partly justified in that drawing mass and energy from another dimension is explicitly part of his powers.) More specifically, the Hulk's healing factor is much like his strength level in that it's tied into his emotional state. The Hulk not only gets stronger as he gets angrier, he also heals faster. Apparently, Hulk's healing is so fast that it took years for anybody to even notice it existed. He regenerates so quickly that nobody could tell that attacks could actually damage him to begin with.
** As Red She-Hulk, ComicBook/BettyRoss is also capable of rapidly regenerating injuries such as the severe injury after being impaled by Skaar's massive sword.
* Iceman could be considered to fit this trope -- he once had a giant hole blown in his chest while in ice form. He was quite reasonably afraid of dying if he changed back but when he did it was as if the injury had never even happened in the first place.
* Courier of Creator/MarvelComics has the ability to regrow body parts, but [[RequiredSecondaryPowers can't create matter]], so when he had to regrow a finger he shrank by one inch.
* SelfDemonstrating/{{Deadpool}} from Marvel also has this (he even got it from the same place as Wolverine got his [[MadeOfIron adamantium skeleton]]), but since he had cancer before getting it, his healing factor caused the tumors to grow out of control and made him horribly scarred and insane [[BreakingTheFourthWall (he thinks he's a character in a comic book).]]
** He has also noted that his couldn't bring him back from the silly lengths that Wolverine's has managed -- although he can regrow fast enough that his friend Cable would [[RuleOfFunny psychically make his head explode for a joke]].
** Well, Deadpool's been shown to recover from being liquefied. When he melted into a puddle, and Cable swallowed him (TO SAVE THEIR LIVES) and then regurgitated him, and Deadpool returned to his solid state almost instantly.
** There is also that time where Wolverine stabbed him through the head. And Deadpool only asked him (with claws just north of his eyes) to move a little to the left so he could [[NoSell ''scratch his brain'']].
** During the ''Secret Invasion'' Deadpool actually weaponized his healing factor by letting the Skrulls use it to make their next generation of Super Skrulls. Only it turns out that when you don't have a horrible ravaging cancer for your healing factor to keep in check, you just keep generating more and more body mass... until you explode.
* Mr. Immortal from Marvel's mutant universe has a unique version: he always recovers from ''fatal'' injury. It's not shown how he'd cope with just normal grievous bodily harm, although this is rarely an issue--typically, he's facing villains who are more than happy to kill him. And if he was just really wounded, all he'd need to do is commit suicide ...
* Marvel's TheJuggernaut also has an incredible healing factor, once continuing to fight after being reduced to an angry skeleton. This is often not noted because, like TheHulk, he is [[NighInvulnerability incredibly difficult to injure in the first place]], with only magic [[AchillesHeel being really able to actually hurt him]]. So the only way you can really face off against him is to teleport him somewhere far away and hope he decides not to come back after you, or use MindControl to make him go away.
* Paul Kirk, one of Franchise/TheDCU's numerous Manhunters, was given his healing factor by a particularly nasty group of {{Well Intentioned Extremist}}s, as (apparently) was one of the clones they made of him, also known as Manhunter. The revival of Manhunter came a year before the introduction of Wolverine, and his power was actually referred to as a "healing factor," so Manhunter's series -- which won many awards in the 1970s but has since fallen into obscurity -- may be the TropeCodifier for modern comic books.
* The vampiric Cassidy from ''ComicBook/{{Preacher}}'' could do this, but he had to actually open up someone's vein before he could heal.
* The 1990s comic book hero ''ComicBook/{{Darkhawk}}'' doesn't exactly have a healing factor, but he can instantly repair all the damage to his android form by [[spoiler:shifting back to his human form, which sends his armor back to the spaceship where it can be almost instantly repaired with nanotechnology, allowing him to summon it back at full strength]]. Injuries to Darkhawk's human body couldn't be healed this way, however.
* ComicBook/{{Blade}} heals far faster than humans, and even faster than some other superhumans with lower level healing factors. Injuries such as stab and slash wounds take care of themselves just fine.
* Even Franchise/SpiderMan is shown to have a limited version of this ability, although it seems more that he can just heal faster from injuries that any normal human can recover from, with bruises and sprains often disappearing only a day or two after Spidey is hurt. He certainly isn't MadeOfIron to the extent that Wolverine and the Hulk are, however.
** It's been explained that Spider-Man's body has gained some properties of a spider's exoskeleton. His outside gets the hits, and his insides stay relatively undamaged. That may not be how science works, but the "RADIO-ACTIVE SPIDER BITE" people probably aren't too worried about the hard facts.
*** It was initially explained as the relative healing of a spider. And that makes no sense, because humans heal ''faster'' than spiders. The exoskeleton remark makes a bit more sense. It would make it harder to injure him, but it would affect his weight and movement. He would also have to shed it.
** Curt Connors used lizard DNA to regrow his amputated right arm, which successfully gained him this power but also made him an unwilling villain. In [[Film/TheAmazingSpiderMan the movie]] he heals from machine-gun fire and grows new limbs in seconds.
** The ComicBook/{{Venom}} and ComicBook/{{Carnage}} symbiotes are also close to immortal, where they can heal from anything but continual and ongoing exposure to high-pitched sounds. ComicBook/TheSentry once ripped Carnage in half (in outer space, no less) but he still somehow managed to come back. The hosts are more vulnerable--Cletus Kasady lost both his legs thanks to that, but when the symbiote returned to him he was able to walk about freely (though he had prosthetics in-between)--but still recover from most injuries as long as the symbiote is attached to them. The latest Venom host is paraplegic Flash Thompson--he uses the symbiote for limited periods (too long and the symbiote will start controlling his body and thoughts) but as long as he uses it he can walk just fine and is, in fact, a full-blown SuperSoldier.
** ComicBook/NormanOsborn has this, given to him as a {{Retcon}} to explain how he came BackFromTheDead--consequently, this means even impaling his heart with a large spiked object only requires time to recover from; the in-universe explanation is that he always had it (i.e. ever since getting his powers) but hadn't noticed since he had never been ''that'' badly injured before (he is MadeOfIron and can shrug off small caliber bullets, so that helps a bit). It is unclear to what extent writers remember that he ''has'' this power--when fighting Spider-Man, he has since recovered from being hit by a bag of bombs and falling hundreds of stories to the ground while aflame (all at the same time); survived a point-blank explosion from [[PersonOfMassDestruction Nitro the Living Bomb]] being buried alive in a collapsed elevator shaft (along with Peter--Osborn recovered almost instantly, if he was badly injured at all, but Peter was in hospital for days); and many, many savage beatings from Spider-Man including one that culminated in having his head smashed in with a lamppost, caving it into concrete--again, he recovered within days, if not hours, off-panel, and was in perfect health when we next saw him. Some stories, however, seem to suggest that he can be killed rather easily--ComicBook/{{Hawkeye}}, for instance, was going to shoot him with an arrow, and the plot seemed to imply that that would do the trick. Almost no story since his return explicitly mentions his healing factor by name either.
* ComicBook/TheSavageDragon can regrow lost limbs, albeit slowly. One villain actually used this against Dragon by breaking every bone in his body, then stuffing him down a smokestack so he healed all wrong. To fix him, another hero had to break his bones ''again'' to let him heal correctly.
* 1990s hero ''Xombi'' has a {{Nanomachines}} based healing factor. It's treated more realistically in that the title character ''does'' explicitly need raw organic material to properly heal. In the first issue, his lab assistant is partially devoured when she rests her body against his own while he's healing.
* ComicBook/GreenArrow II, Connor Hawke, was [[EmpoweredBadassNormal granted]] healing powers by the machinations of [[MadScientist Dr Sivana]] in an issue of ''Green Arrow and Black Canary''. Sivana gave him that healing factor using bits of ComicBook/PlasticMan, a character that has survived being turned to stone, shattered, and having the pieces scattered around the ocean floor for over 1,000 years. Yeah, Plastic Man takes this trope to the extreme. However, Plastic Man doesn't actually heal. He's just {{Nigh Invulnerab|ility}}le as the result of having total control over his physical structure. It's the same principle that allowed him to change back to his regular shape whenever Circe turned him into an animal.
* In ''ComicBook/ImmortalIronFist'', this is one of the explicit abilities of the Cobra Warrior of Peng Lai. Old Cobra once reversed his aging to become a young man again, One Armed Cobra regenerated his long-missing arm, and Fat Cobra managed to grow back both of his legs and repair his severed spinal cord after a fateful encounter with the multi-headed dragon Xiang Yao.
* ComicBook/{{Mystique}} may have a healing factor, or it may just be an extension of her shapeshifting; it's kind of on the fence, and can vary from series to series.
* ComicBook/{{Raven}} of the ComicBook/TeenTitans is able to heal herself by drawing [[AWizardDidIt magical energy]] from the emotions of others. Even with this power, she still falls into comas while healing on a few occasions.
* Although hurting Franchise/{{Superman}} is pretty hard to begin with, if you manage it, he will recover quickly. He once recovered from a slit throat minutes afterwards. It's unknown if this is a power of his, or just an above-average recovery time that has nothing to do with yellow-sun radiation.
** It depends on which version you're talking about. Gold and Modern Age Kryptonians were genetically engineered. Yellow solar radiation makes it happen faster. Silver age Kryptonians were normal humans on Krypton. When surrounded by a Red Solar Forcefield, Superman was human but escaping "shredded every tendon in his legs." Upon escaping "his tendons instantly repair and all the pains of humanity melt away."
** Doomsday, in ''ComicBook/TheDeathOfSuperman''. He's borderline Type I as it takes someone in Superman's weight class to even take him on and then, he can regenerate from anything, including death. The process actually [[InformedAbility supposedly]] makes him stronger each time with a new defense adapted to whatever killed him so he can never be killed the same way twice so in theory he's approaching Type I. He's shades of Type 4 also as, unlike some of the others on this list, when he's killed he actually stays dead for days or weeks.
* DependingOnTheWriter, Franchise/TheFlash uses his super speed as essentially a form of Healing Factor; he experiences the normal healing a human body is capable of, but at a much faster rate. Kid Flash/Impulse, who shares the same power set, has to deal with one of the downsides when Deathstroke shoots his knee with buck shot: his super speed lets him heal very quickly, but without extracting the buck shot and setting the bone correctly his leg will be essentially useless. Making it worse, his super-metabolism also makes him ''immune to pain medicine'', meaning he had to be awake while his bones were re-broken, set, and the metal was removed.
* Comicbook/ManThing seems to come back from anything as long as he is in proximity to water.
* Holden Carver of ''Comicbook/{{Sleeper}}'' has a healing factor as a {{Required Secondary Power|s}}.
* {{Space El|ves}}f Jedi Master Fay from ''ComicBook/{{Republic}}'' #55 has a healing factor due to her deep connection to the Force. Unfortunately, it fails at a crucial moment because of her [[HeroicSacrifice giving her Force reserves to Obi-Wan]] to help him jump to safety. As a result, she ends up dying from stab wounds inflicted on her by Asajj Ventress.
* Franchise/TheDCU's Shade is one of these. No matter what you do to him -- shoot him full of bullets, blast him to pieces, rip out his heart -- he'll always regenerate his injuries. The only way to kill him permanently is to take away his shadow, removing his powers, then deliver a killing blow. In one potential future, he's still going strong after several millennia.
* Also in the DCU are the [[ComicBook/BlackestNight Black Lanterns]], which can regenerate FromASingleCell and can usually only be destroyed by the combined light of a Green Lantern and any of the other colors.
* ComicBook/VandalSavage is another DCU example; he got his immortality from a meteor back during the Cro-Magnon era. He possesses one (as well as other powers) that considerably slow his aging process to the point of it being almost nonexistent.
* The Five Archons in ''ComicBook/TheSecretHistory.'' They can be killed, probably, but they're certainly not easy to kill.
* Mildly deconstructed with Jaeger in ''ComicBook/{{Finder}}'': he has superhealing (as well as being a mild Comicbook/{{Wolverine}} {{Expy}} in other ways), but if he ''doesn't'' get injured for too long a period it makes his immune system overactive and he gets auto-immune diseases.
* ComicBook/{{Luke Cage|HeroForHire}} has one of a similar sort to Spidey's, in that he heals faster than a normal human but can be harmed (not that much gets past that skin of his).
* Minor Marvel villain Madcap also has a healing factor. It's a BloodlessCarnage variant, and he can still control his body parts if they're detached. In the words of his severed head:
-->'''Madcap''': I'm indestructible. No, that's not right...you can destruct me. What's the word for when, no matter how bad you Humpty my Dumpty, I [[PersonAsVerb Wolverine]] myself back together again?
* Comicbook/{{Deathstroke}} has some form of accelerated healing, though [[DependingOnTheWriter no one's kept track of how strong it's supposed to be]], other than the fact that it's weaker than Wolverine's.
* ''ComicBook/BatmanEndgame'' revealed [[spoiler: ComicBook/TheJoker has this power, explaining how he got his face back after ''ComicBook/DeathOfTheFamily''. It is then subverted because it turns out Joker just got his hands on a Lazarus pit]].
* ComicBook/{{Morbius}} was quite surprised to find out his transformation into a [[OurVampiresAredifferent pseudo-vampire]] had given him accelerated healing, which he discovered after he was shot and woke up a little while later with the bullet hole gone. He can heal from a lot and does so faster than normal humans, but it definitely has its limits.
* In his wolf form, ComicBook/WerewolfByNight can heal from just about anything, as long as it's not silver through the heart. He also heals much faster as a wolf than as a human.
* ''ComicBook/{{Aquila}}'': Aquila and the rest of his "brothers" who serve The Devourer can recover from wounds that would kill any normal man, but it does take some time for them to heal (varying from anything to a few hours to several days depending on the severity).

[[folder:Fan Works]]
* ''Fanfic/ChildOfTheStorm'' has a number of characters with varying degrees of this owing to its heavily superhero influenced setting, including Wolverine, the Hulk and pretty much every Asgardian.
* In the WesternAnimation/JackieChanAdventures fic ''Fanfic/QueenOfAllOni'', Jade has a healing factor as part of her new powerset, as well as the Horse Talisman from canon (see WesternAnimation below).
* In the ''Manga/FairyTail'' fic ''Fanfic/{{Necrophobia}}'', [[spoiler: Marion Gremory has one that's ludicrous enough to give ComicBook/{{Wolverine}} a run for his money]].
* Vampires in ''Fanfic/{{Luminosity}}'' have this. Even if someone tears them apart, unless the flesh is actually kept separate, they will regroup and regenerate. There's only one [[StealthPun surefire]] way to kill one. [[spoiler:And Bella found a way around ''that''.]]
* In ''Fanfic/FalloutEquestriaPinkEyes'', the lead character Puppysmiles is a [[OurZombiesAreDifferent Canterlot Ghoul]]. This Puppy can survive outrageous injuries. Her list so far includes being dismembered and devoured by a manticore, taking several antimateriel rifles to the chest, and being cut to ribbons by a Minigun barrage.
** Taken UpToEleven with [[TheBigGuy Rampage]] in ''Fanfic/FalloutEquestriaProjectHorizons'', whose Healing Factor makes her flat-out immortal. She has recovered from [[BodyHorror extensive Taint mutation]], [[BoomHeadshot headshots]],[[OffWithHisHead being beheaded]], being blown up, leaping into a woodchipper and even being completely [[DeathRay disintegrated]]. In the latter few cases, she regenerates as a filly, regaining her adult body in the course of several days. Her healing factor also renders her ImmuneToDrugs, meaning that if she wants to get drunk, she generally has to poison herself with, say, washing detergent beforehand. While making her a valuable asset to the team, it only serves to aggravate her; she's a DeathSeeker, and would like little more than a way to get herself killed, permanently.
*** In the third volume of Horizons, Blackjack herself gains a healing factor of her own, courtesy of [[spoiler:{{Magitek}} [[WeCanRebuildHim cybernetics]]. Even her mechanical parts regenerate, if supplied with - [[ExtremeOmnivore ingested]] - scrap metal]].
** In the original ''Fanfic/FalloutEquestria'', Littlepip gains a healing factor after suffering taint exposure. Like the Fallout example below, it regenerates her limbs when she's under the effects of advanced radiation poisoning. On one occasion, it allows her to regrow an entire leg.
* In ''[[FanFic/SovereignGFCOrigins Origins]]'', a ''Franchise/MassEffect''[=/=]''Franchise/StarWars''[[spoiler:[=/=]''[=Borderlands=]''[=/=]''[=Halo=]'']] MassiveMultiplayerCrossover, Sarah has this [[spoiler:likely due to a combination of Siren and Force powers]], as do [[spoiler:the Flood]], having incorporated bacta into themselves. Some ships use [[RidiculouslyFastConstruction digistruction]] to much the same effect.
* [[spoiler: Dread Raven]] combines this with TheUndead to achieve {{Immortality}} in FanFic/TheTaintedGrimoire.
* In ''Fanfic/GoldenDawnLostSunrise'', [[spoiler:Tidepaw]] receives several wounds in a fight. However, when they ask the Clan's medicine cat for some herbs, the medicine cat points out their mysterious lack of wounds. [[spoiler:Despite this, the scar on Tidepaw's forehead has never healed. In fact, it's still as fresh as it was when she first received it.]]
* Lauren develops one in the ''Series/LostGirl'' fic [[http://www.fanfiction.net/s/8180681/1/Mad-World Mad World]]. It eventually develops to the one point where she can take the wound of somebody else (curing them), and then heal herself. Though she's not as fond of this one.
** Unfortunately this turns into a major BlessedWithSuck when she's captured by a really sadistic Fae, as the fact that she heals from his torture just means he can torture her again.
* Tails gets one when he is infected by Shroud parasites in ''FanFic/SonicXDarkChaos''. At one point, he regenerates most of his internal organs after Tsali tears them out of his chest. This bites back hard during the final battle when he gets possessed by Dark Tails; the resulting mutation causes his body to start [[BodyHorror literally falling apart]], [[AndIMustScream which starts to heal him, which makes him fall apart again]]...
* This part of the earthpony magic in ''Fanfic/TheImmortalGame'', aside of SuperStrength. [[PhysicalGod An alicorn]], who have world-class earthpony magic can survive being impaled, or burned. Even with injuries that could kill regular pony hundred times over, an alicorn can recover in an instant.
** Applejack is especially strong with this. Her earthpony magic is notably stronger than [[PhysicalGod Luna]]. Combined with magic-enchanted armor and SuperStrength, she's a borderline {{Nigh Invulnerab|ility}}le.
* In the ''Fanfic/PonyPOVSeries'', Alicorns have the ability to regenerate very rapidly, having ThePowerOfCreation. Draconequui play with this, as they erase damage instead of healing from it.
** The Element of Generosity has a version of this trope, as Rarity's healed to full health whenever the Elements are used. She eventually figures out how to split this effect between her and her friends.
** In the [[BadFuture Dark World]] arc, the Dark World Mane Six have this ability thanks to their Elements of Chaos acting as a SoulJar. So long as it's not destroyed, they're rapidly heal from any damage taken. This makes Rarity's HealingHands power more practical, as to do she ''takes'' a team mate's injury into herself.
* ''Fanfic/TheBridge'':
** Alicorns have this, with Princess Luna only needing a few hours to recover from a black eye and broken wing. Luna and Celestia heal even faster [[WonderTwinPowers when near each other]].
** All in Godzilla's family have this ability, though each injury leaves invisible scars that turn visible when they are weakened. His cousin Raiga's is a bit slower, but can be sped up by absorbing electricity.
** The Ghidorah species all have this. Grand King Ghidorah once grew back a head and shrugged off getting a nasty looking gash. Monster X healed from multiple stab wounds overnight, and Kaizer Ghidorah can speed his healing up and recover from several broken bones by [[VampiricDraining feeding on someone]]. After Aria Blaze [[EmotionEater steals some of Kaizer Ghidorah's energy]], she gains this ability.
** The Guardian Beasts like Gamera and Anguirus can slowly heal by resting and using up their stored mana.
** The Gyaos and Gaira both only need about a day to recover from broken bones and lost limbs.
** Gigan has one, but since he's a cyborg, it only benefits his organic parts and he needs someone to fix his robotic parts.
** Enjin can heal from pretty much anything, even a broken neck, in a matter of seconds or minutes, [[AdaptiveAbility then become immune to whatever damaged him]]. Even his mask repairs itself when damaged. [[spoiler:However, it only works if he's touching the ground, so if he's knocked into the air, he can be killed.]]
* In ''Fanfic/FateParallelFantasia'', Servants can recover from any injury that doesn't destroy their head or heart, provided they have enough of a supply of magical energy to draw on. This makes the Servants corrupted by False Avenger a significant threat, since unlike the heroic Servants they can draw unlimited energy from the Grail.

* Brandon Lee's character in ''Film/TheCrow'' seemed to possess this ability. Right to the point of making a very bad religious joke in between successive on-target shotgun blasts. [[FatalMethodActing Too bad the actor wasn't so endowed.]]
* The titular character's healing factor in ''Film/{{Deadpool|2016}}'' gets used a lot in the film going from being shot in the hand, surviving a car crash without any long term injuries, regrowing his hand in less than a day after cutting it off, and even [[spoiler:waking up after being impaled by Ajax on a piece of rebar to trap him under the burning Weapon X building]].
* The Neo-Vipers from ''Film/GIJoeTheRiseOfCobra'' have one thanks to the [[{{Nanomachines}} nanomites]].
* In ''Film/{{Godzilla 2000}}'', the genetic origin of this (dubbed "Organizer G-1") is explicitly described as the ultimate source (in combination with its sheer mass) of Godzilla's [[NighInvulnerability apparent immunity to attacks]]. It's so powerful, in fact, that the invading aliens utilize it in order to give themselves physical form (though the plan backfires and causes them to revert to the powerful but nonsentient {{kaiju}} "Orga").
* The ''Franchise/{{Hellboy}}'' films:
** Sammael from ''Film/{{Hellboy}}'' can heal from any non-fatal injury almost instantly.
** The [[SteamPunk Clock Punk]] robots of ''Film/HellboyIITheGoldenArmy'' can repair themselves after being ripped to pieces.
* Immortals from ''Film/{{Highlander}}'' have fast healing, recovering from non-fatal injuries just as fast as deadly ones. The only injuries they do not heal from are ones to the neck - this is why they can only be killed by cutting their heads off (according to ''Series/HighlanderTheRaven'', severing their spine by any other means also works and they can't regenerate limbs).
* In ''Film/TheLeagueOfExtraordinaryGentlemen'', Mina and Dorian actually wonder if they can be killed. They both heal from their wounds in seconds during their fight, prompting Dorian to note, "We'll be at this all day." Their healing factor is based on different abilities, though. In Mina's case, it's because she's been [[spoiler:bitten by {{Dracula}} and is now a vampire]]. In Dorian's, it's because [[spoiler:his [[Literature/ThePictureOfDorianGray portrait]] takes all his age and damage for him]].
* John Oldman in ''Film/TheManFromEarth'' is unsure whether he has a full-fledged healing factor, (for instance, if you shot him, would the wound heal in front of your eyes, or would he drop dead?), and has gone out of his way to avoid testing it. All he knows is that he doesn't age (he looks 35 despite claiming to be ''14,000'' years old) or scar.
* Jeebs from ''Film/MenInBlack'' has an incredibly effective healing factor as his alien ability. Every scene with Jeebs involves him getting his head shot off, only to have it grow back in the space of seconds. The RPG specified that he had a limited number of several vital organs, including his head. The animated series said his species didn't need to breathe oxygen, but needed it to regenerate. The healing factor didn't apply to ''all'' his physiology. After shooting him, K threatens to shoot him again in a place "where it don't grow back." By the sequel, his head looks misshapen from the repeated shootings by J. WordOfGod is that his organs don't grow back exactly as before.
* In ''Film/StarTrekIntoDarkness'', Harrison's blood allows his cells to heal at an astonishing rate, which he uses to heal a sick girl in the beginning in exchange for a favor. Later, Bones revives a dead tribble with it, [[spoiler:and then uses it to save Kirk]]. Supposedly, this is something that was invented in TheSeventies.
* ''Franchise/{{Terminator}}''
** The T-1000 from ''Film/Terminator2JudgmentDay''. It's too bad that a lot of scenes from the end were cut, and are thus not canon. The protagonists did enough damage over the course of the movie, specifically highlighting the freeze-and-shoot moment, that the T-1000 isn't able to completely maintain his form. Moments include grabbing a handrail, and having his fingers stick and assume the color of the warning paint, and while he walks his feet tends to melt.
*** This is also what tips John Conner off that his mom is the T-1000 in disguise.
*** In addition, it has its limits, as it [[spoiler: gets blown up with a grenade from the inside, and can't repair its mangled form because of the pressurized impact and heat. That and its fall into molten steel]].
** T-3000 from ''Film/TerminatorGenisys'' also insta-heals from bullet wounds.
* The title character of the ''Film/{{Tomie}}'' series of J-horror films has this ability to the extent that [[StarfishCharacter every single individual piece of her that is cut off will eventually become a new Tomie]]. This is justified, at least in the manga it was based on, by Tomie being radiotrophic, feeding on background radiation in the air & somehow converting it into mass.
* Vampires and Lycans all have an advanced form of this in the ''Film/{{Underworld}}'' series. While Silver rounds can kill Lycans, they can use their healing factor to push the rounds out and heal the damage. Vampires eventually get around this by using liquid rounds that release Silver Nitrate into the bloodstream, preventing the healing factor from working effectively. Hybrids have an even more advanced case of this.
** Taken UpToEleven with [[TheDragon Quint]] in ''Film/UnderworldAwakening'', who can heal from any wound almost instantly. [[spoiler: [[HoistByHisOwnPetard This screws him]] in the end, as Selene punches a hole in him, and leaves a grenade inside. The wound heals, trapping the grenade inside him]].
* The Djinn in ''Film/{{Wishmaster}}'' have a ramped-up healing factor as part of their CompleteImmortality. They ''can'' actually be hurt (as the Djinn in the first film demonstrates by blowing its own brains out, which he concedes hurt a lot), but the damage just repairs itself instantly.
* One of the upsides of being a werewolf in ''Film/TheWolfman2010''.
* ''Film/XMen'':
** Wolverine. And ''how''. By the end of ''Film/XMenTheLastStand'' his flesh is being torn from his body at an alarming rate only to regenerate just as quickly. (This was explained in the novelization as being accelerated and enhanced even further than normal by the energy Jean was putting out.) He also survives a ''nuclear bomb'' in the opening of ''Film/TheWolverine'' and his body is left a charred and scalded mess from the affair. However, it seems like the film Wolverine's healing factor is not as absurd as the comic book Wolverine's healing factor, considering that decapitation is treated as a viable option in his solo films. [[spoiler:''Film/XMenDaysOfFuturePast'' also presents drowning as an effective method, though he was fished out before it could take.]]
*** In ''Film/TheWolverine'', he loses this, which is suppressed by the Yashida Corporation, through technological means. [[spoiler:At least until he figures out how they did it and rectifies the problem.]]
** Lady Deathstrike in ''Film/X2XMenUnited'', since it's necessary to get adamantium.
** In ''Film/XMenTheLastStand'', Wolverine fights a mutant who can regrow limbs instantly-- but is not immune to a GroinAttack.
** Victor Creed in ''Film/XMenOriginsWolverine''. Although if Stryker is to be believed, it is not as effective as Logan's (which is why he can't undergo adamantium augmentation). It does allow him to live an unnaturally long life, however.
** In ''Film/XMenApocalypse'', the villain Apocalypse transfers his essence into an ancient Egyptian mutant who could regenerate from any wound to acquire this power for himself.
* In ''Film/{{Warlock}}'', witch hunter Redferne stabs the Warlock to kill him, but finds that even the incomplete Grimoire gives the Warlock the power to recover from the wound almost immediately.
* The people infected by the [[PuppeteerParasite alien parasites]] in ''Film/AlienRaiders'' can regenerate most body parts. When the heroes lose their usual method of telling whos infected, they resort to [[{{Fingore}} cutting off the pinkie fingers]] of every potential host and waiting to see if it grows back.
* In ''Film/EndOfDays'', Satan quickly heals [[DemonicPossession his host]]'s wounds after Jericho shoots him. Near the end he suffers so much damage that he doesn't even bother repairing it anymore and starts looking for a new body because he's running out of time to complete his plan.
* ''Film/{{Spawn}}'': Spawn got the ability to heal wounds as part of his deal with Hell. He notes this with satisfaction when Jessica pumps him full of lead.
-->'''Spawn:''' ''Damn...''
* This ability is given as a reason for Jason Voorhees' longevity in the tenth ''Franchise/FridayThe13th'' movie, ''Film/JasonX''. Because he can heal any wounds, authorities have given up on trying to execute him, and just try to cryogenically freeze him instead (until they get the bright idea to use him in scientific experiments).
* Kaulder of ''Film/TheLastWitchHunter'' has this in addition to his immortality. Lesser wounds heal in seconds and broken bones need less than a minute to mend themselves.

* In the ''Literature/LoneWolf'' gamebook series, the various Healing disciplines. Most of the time they are just granting GradualRegeneration, but there are instances when they can explicitly save the protagonist's life from grievous injuries, poisoning, or diseases. Especially with Curing by the rank of Archmaster, or the Grandmaster discipline of Deliverance, which can heal 20 [[HitPoints Endurance Points]] even in the middle of a fight if the total falls too low, though only once per adventure.

* In the ''Literature/{{Alterien}}'' series, the Alteriens can regenerate damaged tissue and bone from severe injuries.
* The high spirits of Adam R. Brown's ''Literature/AstralDawn'' series can quickly recover from psychic wounds inflicted by astral weapons.
* Billy "Carnifex" Ray from the ''Literature/WildCards'' series of novels is a slight subversion; he has one that acts as the biological equivalent of "meatball surgery". It will save his life and restore practical functionality, but repeated injuries have left him somewhat misshapen (e.g. a broken nose healing while still bent out of place).
** Demise has the sort that just keeps bringing him BackFromTheDead.
** The Mechanic's healing factor required him to be in contact with a machine.
** Stuntman's healing factor regrows the damaged tissue violently, leaving him disoriented and very hungry.
* Jordan the Barbarian from the ''Literature/{{Xanth}}'' books has regeneration as his magical talent, allowing him to recover from anything (''anything'') up to and including death... so long as his body parts are fairly close to each other. However, after being reunited with himself at the end of a 400-year period of being sliced up and scattered, he did need a lot of food to fully recover.
* In Creator/DianaWynneJones's ''Literature/{{Chrestomanci}}'' series, nine-lived enchanters can recover from mortal injuries such as a broken neck or 100% burns, but only eight times, and it ''does'' indeed make them very hungry.
* Cormac limbs from ''Literature/TheSagaOfDarrenShan'' has the ability to regain lost body parts, when you cut off his head, two smaller heads appear. The guy who decapitated him was suitably freaked out.
* Wizards in ''Literature/TheDresdenFiles'' have a slight healing factor, which allows them to live for centuries and heal any injury perfectly and without scarring. Harry notes at one point that, given the abuse he's faced over the years, he'd be facing the kind of constant aches and pains a retired football player does if not for his healing factor. They don't heal injuries any faster than a normal human would, though, and any physical trauma that would kill a normal will kill a wizard.
** Best shown when a nasty encounter with a flamethrower in book 6 left Harry's hand char-broiled. He eventually regained use of it, but only after at year or two (several books) of recuperating and physical therapy. Even then, it's going to be a while before it completely heals. In ''Skin Game'', which takes place years later, his hand still looks like melted wax.
* The Specials in Scott Westerfeld's ''Literature/{{Uglies}}'' series have {{Nanomachines}} in their blood that allow them to heal quickly.
* This actually seems to be pretty common in books by Creator/BrandonSanderson.
** Mistwraiths and some Allomancers in the ''Franchise/{{Mistborn}}'' books both have rapid healing. Mistwraiths because they can simply alter their body mass into muscle or other kinds of tissue (though they can't create or repair bone), while any Allomancer that can "burn" pewter will gain super-human healing (though we're talking a week or two to recover from a should-be-fatal cut, not regrowing arms in minutes) in addition to the other benefits it provides.
** The [[TheDragon Inquisitors]] and ''especially'' the [[EvilOverlord Lord Ruler]] have this even moreso. Inquisitors can regenerate from almost any injury, though it takes up a lot of their energy, while the Lord Ruler has been at various points in his {{Backstory}} shot, stabbed, decapitated, burned alive, and ''flayed''. He shrugged off all of them in minutes, with no significant harm done. WordOfGod is The Lord Ruler wasn't fully decapitated - he only had his neck chopped about three-quarters of the way through. Similarly, when he was burned alive, only the outer layer of skin and muscle was burned. If he had been completely decapitated or burned down to the bone, he would have been killed, but considering how [[PhysicalGod powerful]] he is as a combatant, this is a lot easier said than done.
** Feruchemists can save up their health in "goldminds" (feeling horribly sick the whole time) then splurge it all in one burst of incredibly fast regeneration. The Inquisitors' and the Lord Ruler's even-faster healing comes [[spoiler: from their ability to combine Mistborn and Feruchemical talents]].
** [[spoiler: Miles]] in ''Literature/TheAlloyOfLaw'' manages the most impressive one. His healing factor is ''so'' powerful, he shoots himself in the face with a shotgun just to show off. Repeatedly. Without being even temporarily incapacitated. While possessing no other superhuman powers. It's noted he carries around sticks of dynamite to alleviate his one weakness - that, as he possesses no other superhuman powers, he can be disabled pretty well by tying him up - although you need either well designed nets or several men to do so, because his healing factor still makes him deadly in hand-to-hand. To get around this, he simply takes the dynamite out and blows himself up, destroying the netting in the process. He doesn't really care because his healing factor has been going so long he can't actually feel pain any more. His is so powerful that even when completely deprived of the very gold he uses to power it, it still takes a firing squad ''four entire volleys'' to actually kill him because he kept healing.
** Surgebinders in ''Literature/TheStormlightArchive'' heal much faster, can regrow amputated limbs, and cannot be killed except by a Shardblade or a blow to the head while holding Stormlight. Even stabbing one of them through the heart won't kill them if they're holding enough Light.
** In ''Literature/{{Elantris}}'' Both Elantrians and Dakhor heal somewhat faster than humans.
** These all share a specific quirk, however: They won't heal any ailments which agree with one's self-image. If you see yourself as a eunuch, your equipment won't grow back. If you see yourself as bald, your hair won't grow back. If you require glasses, your eyes won't heal unless you want them to. This is a plot point in ''Literature/WordsOfRadiance'', when Kaladin can't get his SlaveBrand tattooed into something less dangerous to his well-being because of his emotional baggage.
** In ''Literature/TheReckonersTrilogy'', Limelight gets a powerful healing factor as one of his Epic abilities.
* In P.C. Hodgell's ''Literature/ChroniclesOfTheKencyrath'' series, the Kencyr peoples have impressive healing abilities, although much of it requires ''dwar'' sleep, a hibernation-like mode of deep, restorative sleep which can, for severe injuries, last for weeks. Jame, the protagonist, sleeps for thirteen days after she arrives in Tai-tastigon with severely infected haunt bites (haunts being essentially zombies); her healing astonishes the human healer who tends to her. Kencyr can also regenerate lost teeth, and through ''dwar'' sleep can recuperate from punishing speeds on foot, allowing their armies to cover ground at a sustained rate much faster than human armies can attain.
* Averted, and possibly inverted, in ''Literature/TheBelgariad'', where the gods have ''no'' healing ability whatsoever because they're normally invincible and have no need of it. [[spoiler: Meaning that when the BigBad Torak is badly maimed, his injuries, consisting of horrible burns and a destroyed eye, remain exactly the same as when Torak received them, pain and all, even after thousands of years.]]
* The [[spoiler: Father of Titans]] from the ''TabletopGame/{{Warhammer 40000}} Literature/GreyKnights'' novel ''Dark Adeptus'' has one that allows for real-time regeneration of fairly severe damage, [[spoiler: though not direct, explosive core sabotage]]. The Grey Knights themselves, as {{Super Soldier}}s, have a better-than-human regeneration, though they still need an apothecary for severe stuff.
* In Octavia Butler's ''Literature/{{Fledgling}}'', the [[OurVampiresAreDifferent protagonist]] recovers from being caught in a burning building--it's implied that she had severe head injuries and was ''blind'' at the start. At the end of the process, she's fine except for the amnesia, but she needs fresh meat as soon as possible, and is too hungry to notice where it comes from. [[spoiler: It's one of her brother's human friends, who was there trying to find and rescue her.]]
* As the Franchise/DoctorWhoExpandedUniverse Literature/EighthDoctorAdventures are a bit BloodierAndGorier than the ''Series/DoctorWho'' TV series, it's much more evident that the Doctor has a certain degree of this ability in the novels than it is on TV. The Doctor regrows a tooth at one point. He walks on a severely broken leg, is severely stabbed, gets shot full of buckshot, has [[HeartTrauma one of his hearts]] [[MadeOfPlasticine ripped out]], [[RealMenGetShot etc.,]] and always gets better with a minimum of fuss and no medical attention.
* Tempus from ''ThievesWorld'' has a healing factor that was given to him by his patron god Vashanka. However, as this is ThievesWorld and Vashanka is the [[spoiler: sister-raping, brother-killing, mage-hating,]] generally nasty Rankan war-god, there's [[BlessedWithSuck obviously going to be a catch]]. In this case, Tempus heals from anything that doesn't kill him ''at about the normal human healing rate''. This is particularly crap when [[spoiler: he gets all his limbs and his tongue cut off by a serial killer who doesn't realise he's damn near immortal]].
* In the ''Literature/ParrishPlessis'' series, one of the abilities granted by TheCorruption is enhanced healing. The effects aren't too extreme; the infected can still be killed by mundane means, and still need a while to recover from severe injuries like broken bones. It is, however, quite good at dealing with toxins, which lead some well-intentioned people to start spreading it around as a cure for the pervasive heavy metal poisoning in their slum. [[NiceJobBreakingItHero Then the others side-effects of infection began to appear...]]
* The protagonist of the abominable ''Literature/BaldursGate'' novelisations, Abdel Adrian, gets this in the second book. Due to [[spoiler: his divine blood,]] his injuries will simply heal after a while, even when bits come off. This mainly serves to counterbalance the fact that, even though he's an awful CanonSue, he kind of sucks at fighting. Also, it increases the {{gorn}} potential by letting him be sliced up too.
* Lanik Mueller from ''Literature/APlanetCalledTreason'' comes from a family who achieved a Healing Factor through generations of genetic modifications. It takes a ''lot'' to kill a Mueller. (They routinely cut off each other's fingers and pry out eyes in childhood squabbles.) Puberty is kind of spectacular in them: In their teenage years, their healing factor gets somewhat out of control and they constantly grow many redundant body parts. Their body stabilizes once they reach maturity... except for the "radical regeneratives" whose healing factor remains out of control permanently. Such poor souls lose all rights and are treated as cattle from which organs are harvested for trade.
** Halfway through the book, Lanik's body is so gruesomely destroyed that the healing factor malfunctions spectacularly and accidentally regenerates his loose innards into a living conjoined twin. When Lanik recovers from feverishness enough to realize what has happened, he cuts off the twin and kills him in panic... [[spoiler:but the twin has the healing factor too, so it regenerates and becomes Lanik's EvilTwin]].
* Atticus O'Sullivan of the Literature/{{Iron Druid|Chronicles}} books can regenerate almost any injury ... as long as his bare skin is in contact with soil.
* Trolls in Creator/PoulAnderson's ''Literature/ThreeHeartsAndThreeLions'' regenerate unless damaged by fire. This is likely the origin of this concept for trollish regeneration that was later adopted by Dungeons and Dragons.
* Immortals and Marra in ''Literature/TheMadnessSeason'' can both heal themselves of injuries that would otherwise be fatal, so long as they, respectively, have enough blood or life force to spare.
* [[ActionGirl Lu]][[TheHero cy]] from ''Lucy's Blade'' has this, as does anyone who is possessed by [[OurDemonsAreDifferent Lilith]], which means they can't even get sick. But it isn't that super human - a seriously bad wound could still kill them because there is only so much energy Lilith has and is able to pump through a mortal body without killing her friend.
* Killing an engineered in ''Literature/{{Duumvirate}}'' is a matter of either inflicting direct brain damage or making them lose enough blood. Their regeneration isn't what makes this [[DodgeTheBullet difficult]], however...
* Dr. Cherijo Torin of the ''Literature/StarDoc'' novels is this way, thanks to the interference of {{Sufficiently Advanced Alien}}s in the process that created her. She even survives a point-blank gunshot wound to the head, although her [[LaserGuidedAmnesia memories]] and thus personality are severely altered by the event.
* 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 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.
* Vampires in ''Literature/WomenOfTheOtherworld'' are like this. Their only special power is incredible healing. At one point, one vampire who had her throat cut is able to walk and talk a few minutes later.
* [[spoiler: Mirar]] one of the Wilds in Creator/TrudiCanavan's trilogy ''Literature/TheAgeOfTheFive''. He gained immortality through his great knowledge of healing magic. This even allowed him to [[spoiler: survive being crushed under the rubble of a collapsed building, as he used his healing magic to keep his brain and vital organs alive whilst his body repaired itself]].
* ''Literature/{{Animorphs}}'':
** The Animorphs. Even though they're normal kids, the Andalite morphing technology they've been given is based on DNA. If they're injured while in morph, all they need to do is demorph to human and their injuries will be gone. Likewise, if they're injured while human, they just need to morph and then demorph to have a perfect DNA-based body again. No injury, no matter how serious, will kill them unless it kills them instantly. As long as they're still alive and conscious after the injury, they can recover. If they miss their two hour time limit in morph, all bets are off, because after two hours, ModeLock takes place, and you won't be turning back into a human ''ever'' again.
** The Hork-Bajir can heal extreme wounds very fast, such as when Dak Hammee cuts his own head open, shows his brain to the Animorphs, and is able to close the wound simply by pressing the two sides of his cut flesh together. It's not like he isn't hurt from it, but it was clear that the injury was far from lethal, and a scar forms over the cut in moments.
* Anyanwu from Octavia Butler's ''[[Literature/{{Patternist}} Wild Seed'']] is a shapeshifter with an impressive healing factor; she can only be killed by something that would kill her instantly (presumably, decapitation or the like).
* The Dullahans in ''{{LightNovel/Durarara}}'', set in the same world as the above example also appear to regenerate their wounds, though it takes longer for them to heal. It's unclear whether it's possible to wound one badly enough to kill them permanently, but this doesn't seem to be the case.
* Humanity as whole possesses this in Creator/RobertReed's ''Literature/GreatShip'' universe. [[TransHuman Artificial emergency genes and massive amounts of genetic engineering]] allow the body to recycle wastes and such very efficiently, and it can re-purpose mass to be used for other things - chop off someone's arm, and the emergency genes break down the appendix and some less used muscles to regrow it in a few days or weeks.
* Corwin, and by extension, the rest of the Amberites and Chaosites in ''Literature/TheChroniclesOfAmber''. As he says, "I heal faster and better than anyone I know." Notably, this isn't instantaneous, but it is still accelerated compared to normal humans, and is considerably better. At one point, Corwin regenerates his ''eyes'' that were [[EyeScream burned out of his head]] with branding irons, even recovering the optic nerves. It takes a few years, but he makes a full recovery. He and Benedict speculate that Benedict, who has lost an arm, will regrow it given enough time.
* ''Literature/HonorHarrington'' has both quick-heal, which simply massively speeds up normal healing, and regeneration therapies, which can regrow limbs and other things within a matter of weeks, though it simply doesn't work on a sizable percentage of people, including the main character.
* ''Literature/GalaxyOfFear'' has [[spoiler: Eppon]], who can instantly re-form an arm that was severed. Presumably it gets the mass from the same place where it stuffs the [[ImAHumanitarian people it eats]].
* In ''Literature/TheGirlWhoWouldBeKing'', Bonnie and Lola both have a healing factor, though they are initially unsure of exactly how strong it is -- while Lola is able to heal a bullet wound to the leg, she wonders whether she'd be able to recover from a bullet to the head. [[spoiler:They later discover it extends to the point of ResurrectiveImmortality]].
* Several characters in the ''Literature/MediochreQSethSeries'' have this to varying degrees. Dragons have it as a race trait - which kinda makes sense; they are [[TruthInTelevision reptiles]] after all - and Mediochre himself has it to such an insane degree [[spoiler: due to the blood of a dragon being magically bonded with his own in backstory]] that he can't ''age'' [[NotGrowingUpSucks past puberty]]. In the first book, his ArchEnemy Maelstrom has survived this long by repeatedly granting himself a temporary one by [[spoiler: using dragon's blood as a sort-of HealingPotion]], which is ''not'' how it works with real reptiles, but, y'know, [[AWizardDidIt magic]]. Dhampinella's reaction to being shot also seems to imply that Dhampir (and presumably Vampires) have a better healing factor than humans, although clearly not as good as that of dragons.
* The angels in ''Literature/ParadiseLost'' are described as having this, and "[c]annot but by annihilating die." This becomes an instance of AndIMustScream when the rebellious angels are cast into the lake of fire.
* In ''Literature/TheVampireChronicles'', vampires have incredible healing powers. Most wounds (such as a gunshot) heal within seconds. A severed body part can simply be held back at its proper place and it will reattach. It is indicated that the only real way to kill a vampire is to incinerate them and scatter the ashes. Otherwise, it might take centuries, but they ''will'' eventually heal.
* In ''{{Literature/Adaptation}}'' by Malinda Lo, after her operation Reese's scars disappear faster than they should [[spoiler: because the operation was performed by aliens with accelerated healing trying to, "upgrade," human DNA to give humans their abilities]].
* In Creator/WenSpencer's Literature/UkiahOregon series, Ukiah heals much faster and more completely than a human, even if he's killed, although fire will prevent this, as will some poisons. The same is true for the Pack, but moreso, while the Ontongard can put themselves back together in seconds from a shotgun blast to the face.
* In the ''Literature/ParadoxTrilogy'', symbionts can heal from nearly anything that doesn't destroy their head.
* In ''Literature/VampireAcademy'', Strigoi heal from serious injuries, minutes after receiving them. Rose estimated that it would take five minutes for [[spoiler:Dimitri]] to recover from a wooden stake piercing his heart.
* The title villain from ''Mr. Murder'' by Creator/DeanKoontz has this, though played a lot more realistically than most. He can heal even severe injuries, and much more quickly than a normal person, but he requires a ''lot'' of food to fuel the repairs. And if he doesn't have enough, his body will start [[BodyHorror cannibalizing itself]] to keep the healing going.
* The Undying from the ''[[Literature/{{Somewhither}} Tale of the Unwithering Realm]]'' setting are all immortal, and can heal any injury by drawing spilled blood and guts back into their body, and regenerating destroyed body parts. The more experienced ones also have perfect control over their body, allowing a limited, squicky form of VoluntaryShapeshifting.
* In ''Literature/TheSiranthaJaxSeries'' and (more centrally) the ''Literature/DredChronicles'', Jael has the ability to recover from serious injuries quite quickly. This becomes useful not just to himself but to Dred (the protagonist of the latter series), thanks to [[spoiler:blood transfusion after she's injured]].
* In ''Literature/ADarkerShadeOfMagic'', ''Antari'' heal from injuries more quickly than other people.
* The main characters in ''Literature/EdenGreen'' are infected with an alien needle symbiote that keeps them alive no matter what.
* In Creator/DamonKnight's novella ''Dio'' or ''[[https://books.google.com/books?id=aRiNRcxaeBsC&lpg=PA242&ots=a6hRPprQcq&pg=PA209#v=onepage&f=false The Dying Man]]'', humanity has genetically engineered itself into drop-dead-gorgeous immortality. Regeneration is part of the package -- [[GoodThingYouCanHeal injuries hurt]], and you try to avoid them, but you're okay. It's when the lead character has this fail on him -- along with suddenly losing the ability to [[WeWillAllFlyInTheFuture levitate]], that he knows something's really wrong.
* The ''shieldwatch'' in ''Literature/AeonLegionLabyrinth'' can roll back time to when its user was not injured. Its main limitation is that if the user's spine or brain is damaged, then they [[LaserGuidedAmnesia will lose their memory]] once restored.
* Robin from ''Literature/TheGirlFromTheMiraclesDistrict'' discovers at one point that he can heal incredibly quickly from what should be mortal injuries, to surprise of everyone involved.
* ''Literature/TalionRevenant'': Having ''rhasa'' souls in your body allows a person to use them for this.

[[folder:Live-Action TV]]
* ''Franchise/{{Buffyverse}}'':
** Buffy has a lesser healing factor as part of her Slayer powers. She can't regenerate injuries in front of our eyes, but she does recover from serious injury much faster than a normal human (at least if she also gets medical assistance).
** Vampires also have this healing factor, though it may not be as strong as Buffy's. Spike was stuck in a wheelchair for several episodes, and Drusilla was heavily weakened by an attack which required a ritual to heal. In some ways it can be stronger than Buffy's, as vampires are clinically dead, they don't have to worry about things like blood loss.
** Spike recovered at some point before he actually got out of the wheelchair; in one scene, he reveals he'd been faking it for an unspecified amount of time. Angel has been gutted and run through an unspecified number of times, particularly in his spinoff show. Illyria also threw him through two windows several stories off the ground.
** The Mayor's invulnerability manifests as this. He tests it by allowing someone to stick a sword through his head; the two halves sew themselves back together almost instantly.
* ''Series/TheCollector'': Collectors quickly recover from any wound, with Hellfire spewing out of it in the process. A [[DealWithTheDevil client]] also exhibited it (minus the flames) with fatal wounds. Because of the Devil's obligation to clients, they are protected from death for the duration of their deal, one way or another.
* Appears to be the only sort of power ascribed to grim reapers in ''Series/DeadLikeMe'', beyond the ability to yoink souls out of bodies. One example is when George accidentally runs her hand through a paper shredder, losing a finger in the process. She picks it out of the basket, holds it back in place for a few seconds, then goes and washes the blood off her hands.
* Adric from ''Series/DoctorWho'' has this ability, thanks to [[HumanAliens his species']] capacity for incredibly rapid adaptation. It only gets mentioned in two of his stories, though.
** The [[DVDCommentary Info-Text]] for ''State of Decay'' uses this to poke fun at a continuity error regarding a mysteriously disappearing patch and rip in Adric's trousers where he skinned his knee in ''Full Circle'', saying that apparently "Alzarian trousers heal as fast as their owners."
** In the 2005 episode "The Christmas Invasion", the Doctor is shown to be able to quickly regrow severed limbs for up to 24 hours after regenerating, using leftover regeneration energy. In [[Recap/DoctorWhoS32E8LetsKillHitler "Let's Kill Hitler"]], [[spoiler: Melody, who has just regenerated]] is shot with many bullets, but regeneration energy prevents any damage.
* Revealed as an ability that Pilot's race has in a scary early episode of ''Series/{{Farscape}}''. [[spoiler:The crew of Moya, minus Crichton and Aeryn, cut off one of Pilot's arms to trade for maps to their home worlds. Predictably, they get double-crossed so they REALLY mutilated Pilot for no reason.]]
* ''Series/{{Heroes}}'':
** Claire Bennet. She exhibits the power of rapid cell regeneration, a trait that allows her to recover from almost any injury in a matter of seconds. She also feels relatively little pain from even serious injuries, including burns and compound fractures, although she did grimace when her hand was damaged while retrieving a class ring from a running garbage disposal. She has not yet reached a limitation in her powers. Along with the injuries stated above, she suffered an injury where her neck was broken and turned around 180 degrees. However, Claire cannot heal an injury if a foreign object is obstructing the wound. This is true of other characters with healing factors, who can still heal incorrectly, incompletely or not at all if certain conditions are not met, just like normal humans. For example, in the first episode, the bones of Claire's ribs were sticking out at one point. After a comment from Zach brought this to her attention, Claire had to move them around a bit before they would heal properly.
** [[spoiler:Adam Monroe/Kensei]] has the same power and is immortal.
** Peter Petrelli has the same power via absorbing it from Claire ([[spoiler: until Arthur remove all his power]]). Also in Season 3, Sylar, but in a less family-friendly fashion than Peter.
* In ''Series/{{Highlander}}'', immortals don't get sick and beheading is the only way to kill them. Any injury that doesn't happen to the neck or head will heal within minutes, and mortal wounds result in a short-term "death" where their body will shut down and appear dead while it repairs the damage. Once again, in a couple of minutes they're good to go. The most notable exception to their healing power is that lost limbs can't be regrown... a recurring villain whose hand is cut off in a duel in his first episode is still missing that hand in subsequent episodes.
** There was also a recurring villain whose first duel with Duncan centuries ago resulted in his throat being cut. For some reason, it healed improperly, and he has since been incapable of singing opera. He ''really'' hates Mac for that.
* The [[WeCanRebuildHim rebuilt]] Michael Wiseman's new body in ''Series/NowAndAgain'' has a nanite-based healing factor. While it's not as extreme as in some of the other examples on this page, it's much faster than a normal human.
* ''Series/TheOuterLimits1995'':
** In "The New Breed", nanodevices injected into the body provide the test subject with this ability. He demonstrates it by burning his hand, which is repaired within seconds.
** In "Last Supper", an immortal woman who goes by the names "Laura" and "Jade" reveals that she was actually born in mediaeval Spain before her village was ravaged by the Black Death. She was the only one to survive, but hasn't aged or gotten sick since, and all her wounds recover soon enough. A government scientist takes samples of her blood to replicate the effect, [[spoiler:but vastly underestimates its potency when he injects himself with it and de-ages into a puddle of cells]].
* Similar to the comic, the titular character in ''Series/PainkillerJane'' can recover from pretty much any injury that leaves her body largely intact. In the pilot, it takes her no more than 30 minutes to recover from DestinationDefenestration. The "painkiller" is a NonIndicativeName, as she goes through [[ImmortalityHurts extreme pain]] from these injuries that happen with disturbing frequency. In one episode, she is trying to convince a [[DifferentlyPoweredIndividual neuro]] who can make people see things that ''he'' is the one being manipulated. She shoots her own hand and shows it to him as the wound closes in a matter of seconds to prove that none of it is real. However, one GroundhogDayLoop episode has her die by tripping a claymore mine and following the ChunkySalsaRule. The loop resets, so the death doesn't stick. Later, she also finds out that there are others like her. Interesting, they reveal that neither they nor she are TheAgeless, and their (completely healthy) bodies simply shut down when the time comes.
* [[OurVampiresAreDifferent The Wraith]] in ''Series/StargateAtlantis''. Their healing factor is directly dependent on how recently and how much they fed. One notable Wraith is found who has been feeding on both humans and other Wraith for 10,000 years. No matter how much lead is pumped into him, he keeps going. Only a drone strike finally brings him down (by destroying his body).
* The Leviathans in ''Series/{{Supernatural}}'' have this as part of their skill-set. Edgar recovered from having a car crush him, and [[WeaksauceWeakness Borax]], while capable of hurting them, only causes temporary damage. When they have their heads removed, [[PullingThemselvesTogether it reattaches itself]].
* ''Series/TeenWolf'': All the wolves have it. Sometimes they even come back from apparent death.
* In ''Series/TerminatorTheSarahConnorChronicles'', RobotGirl Cameron's epidermal layer heals unusually quickly, to the point that a gaping, deep wound that [[FeelNoPain had to be stapled closed]] healed to the point that is just looks like a recently patched-up cut the next day.
* Captain Jack Harkness of ''Series/{{Torchwood}}'' comes BackFromTheDead whenever he encounters lethal damage. When he does, the damage is healed, regardless of whether it was mundanely or supernaturally inflicted.
** Taken to a disturbing extreme in the series two finale, where he is [[spoiler:trapped in a continual death-resurrection cycle for almost 1900 years after being BuriedAlive]].
** Taken to yet another disturbing extreme in the ''Children of Earth'' miniseries, where he has [[spoiler:a bomb implanted in his stomach. He regenerates from a few limbs and part of a head to a skeleton to his normal self over the course of the day... and starts regaining consciousness and screaming when his skin has yet to come back. The room he's locked up in is promptly filled with concrete, and he's rescued when the team breaks the concrete block by dropping it into a quarry]].
** This regenerating thing of his is not because of a natural, biological healing factor. Poor sod became [[spoiler: a universal constant in the parent series when Rose fixed the past a bit sloppily in her god mode. This peculiar being of his makes him too weird for the time sensitive Doctor]].
** He loses his healing factor in ''[[Series/TorchwoodMiracleDay Miracle Day]]'', and after the Miracle (which stops ''everyone'' on Earth from dying, no matter how badly they're injured) there is speculation that he many now be the only person on the planet who can die. [[spoiler:Once "the Blessing" is given, which is some of his blood from when he was immortal, he regains it, along with associate Rex Matheson]]. WordOfGod is that, while his Healing Factor is gone, his ResurrectiveImmortality remains.
** The ''Torchwood: Web of Lies'' mobile game reveals that Jack's body is full of bullets and shrapnel from every time he was injured or killed since he was first resurrected. Apparently, his body doesn't push all that stuff out, but simply regrows around it. None of it appears to bother him in the least. Most of the metal pieces come out at the end of the game, though, thanks to an MRI magnet.
* The vampires and werewolves of ''Series/TheVampireDiaries''. Vampires heal particularly fast if they drink some blood.
* ''Series/TheXFiles'': Several monsters of the week have this.
** "Leonard Betts" played with the healing factor's similarity to the rapid cell growth of cancers; a man who could regrow his whole body almost at will showed up in lab reports as having a wide variety of cancers, and he needed to ''[[HorrorHunger eat tumors]]'' to survive.
** "Fire" featured a pyrokinetc villain who could control fire. He survived fifth and sixth-degree burns over his entire body and his tissues started to regenerate rapidly.
** In "Young at Heart", a MadScientist experimented with cell growth and salamanders' regenerative power. John Barnett was given a [[ReptilesAreAbhorrent horrifying salamander hand]] in the process.
* In ''Series/TheFlash2014'', all speedsters have this ability, granted by their SuperSpeed. In the pilot, Barry breaks his arm, which heals in 3 hours. Presumably, the bone still has to be set as soon as possible to prevent it from healing improperly. In an ''Series/{{Arrow}}'' crossover episode, Oliver intentionally shoots Barry with two arrows to teach him to be aware of his surroundings. When Barry complains, Oliver reveals that he knew about his healing ability (which doesn't prevent it from hurting like hell).
* ''Series/JekyllAndHyde2015'' gives Hyde the ability to heal from injuries at an accelerated rate.

[[folder:Multiple Media]]
* From ''Toys/{{Bionicle}}'', Kalmah could regrow his tentacle (or at least did so in a mini-movie which is actually a vision that another character sees). Unlike him, Nocturn could regrow his partially mechanical arm but ''not'' the organic tentacle at the end of it. So he attached a gun to it instead.

[[folder:Myth and Legend]]
* [[Myth/ClassicalMythology The Lernaean Hydra]], of Heracles/Hercules fame, was so difficult to kill because for each head the hero would cut off, two would grow in its place. The fact that its blood was also a [[BloodyMurder deadly poison]] didn't help either. Only when his nephew Iolaos started to cauterize the stumps with his torch could Heracles finally kill the monster; this may be the (or at least one) source for the idea that fire is bad for regenerators.
* The Lambton Worm was a serpent or dragon in English folklore that could heal any injury it took, to the point that it can eventually rejoin segments of its body that have been hacked off. The only way to defeat it was for the local lord to wear a suit of armour covered in spearheads fight in a river. Where the worm tried to wrap around the lord, the blades on his armor would cut it apart and the running river would wash the individual segments away so the worm couldn't reconnect itself.
* Prometheus had his liver torn out every day, and grown back by the next. Over and over again, [[AndIMustScream for centuries]].
* The Greek gods have this kind of immortality, which includes not aging. According to most writers, they can't die from anything. To add to this, the myths say that Kronos is still alive despite being cut up into tiny pieces and scattered across Eternity. Further, Kronos did the same to HIS father who is also still alive despite that. In fact, Chiron, one of the few GOOD centaurs, ends up needing to have is immortality taken from him somehow since the hydra venom in his body couldn't kill him and just continued giving him horrible, mind-searing pain.

[[folder:Other Sites]]
* ''Wiki/SCPFoundation''. Generally speaking, any SCP item tagged "[[http://www.scp-wiki.net/system:page-tags/tag/self-repairing#pages self-repairing]]" will have this to some degree.

** [[http://www.scp-wiki.net/scp-2102 SCP-2102 ("Got Shoggoth?")]]. As a result of the experiment that created it, SCP-2102 can heal its wounds a quadrillion times as fast as normal. Unfortunately the process doesn't stop when the healing is completed, and the subject's body grows out of control.
** [[http://www.scp-wiki.net/scp-2922 SCP-2922 ("Notes From the Under")]]. When a human being implanted with SCP-2922 dies, they go to an afterlife that the Foundation calls Corbenic. The body they have there regenerates all physical damage it takes in seconds.

* In ''Podcast/TheMagnusArchives'' a character starts mysteriously losing body parts. They don't grow back, but the wounds they leave behind heal instantly.

[[folder:Professional Wrestling]]
* Dino Kang Jr. in Wrestling/KaijuBigBattel. Given a few years, he can regrow limbs.
* Wrestling/JohnCena has actual, no-{{Kayfabe}}, near-superhuman healing abilities. After his first major injury and repair surgery (in October 2007) he was supposed to be out for at ''least'' six months before he could wrestle again. Guess who showed up in the last spot of the Royal Rumble next ''January?'' And ''won?'' Yeah, those numbers don't add up, but it happened, and that's not the only time.

[[folder:Tabletop Games]]
* In ''TabletopGame/DungeonsAndDragons'', the Regeneration ability changes normal damage into subdual damage and the ability to recover so many HitPoints' worth of subdual damage per round. Thus, if you don't use the attack form that ''does'' cause normal damage to the foe, they cannot be killed, merely knocked out for a while. There is also Fast Healing, which merely causes the character to heal a certain amount of normal damage per round and thus allows real death to occur much more easily, shutting off the power just as normal healing would be.
** The ultimate example of this ability is the Tarrasque. Its renegeration ability has no [[AchillesHeel damage type exception]], meaning that no matter what you do to the monster it'll come back eventually unless you use a magical Wish to wish it stayed dead.
** In previous editions, there were particular forms of regeneration that varied from monster to monster. The D&D troll, arguably the most famous example, can quickly regenerate wounds from swords and axes, and by themselves these weapons can't kill them, although they can knock them out temporarily by reducing their hit points to zero. The only thing that ''can'' kill them are fire and acid, which also cause damage that can't be regenerated. Whether you blow them up with a fireball, or knock them out with a weapon and then set them on fire or douse them with acid, you need to burn trolls to kill them if you're using standard tactics. If beat into helplessness, they can then be drowned also if there is water nearby (as there often is as they often inhabit swamps). Trolls being vulnerable to fire is likely originally taken from the novel ''Literature/ThreeHeartsAndThreeLions''.
** 4e Lycanthropes (were-creatures) have regeneration instead of damage reduction, it is suppressed by, you guessed it, silver.
*** Regeneration is used to create {{Puzzle Boss}}es sometimes in the game; However, it occasionally backfires through really counterintuitive or contradictory responses being required, e.g. the Tendriculos, a ManEatingPlant, regenerates from fire and axes, and is vulnerable to ''electrical attacks and blunt weapons''. Another man eating plant has a sort of healing factor in that it ''gains health from being hit by electrical attacks'' (the Shambling Mound).
** Healing Factor is the name of a feat in the ''TabletopGame/{{Eberron}}'' campaign setting. It allows shifters to regain health whenever they return to their normal form.
** In the fourth edition, regeneration works more like the previous fast healing ability and does not function at 0 HitPoints or less. On the other hand, 'special' attacks (fire vs. trolls, silver against lycanthropes) generally only suppress it for one turn before it kicks back in.
** Certain types of Damage Reduction, a defensive ability that reduces the severity of each attack a creature suffers (possibly negating it), are described as wounds closing instantly rather than simply not being as severe as expected.
** ''Everything'' has ridiculously fast healing in 4e. For example, a power called "knee breaker" only lasts a few rounds.
** In the second edition of the game, a sufficiently high Constitution score gave you this ability. The highest natural Constitution for the basic races was 19 [[note]]The highest score that can be rolled is 18, Dwarves got +1 to Constitution and -1 to Charisma[[/note]]. A minimal Con. Score of 20 was required for basic regeneration.
* Most supernaturals in both [[TabletopGame/OldWorldOfDarkness Old]] and ''TabletopGame/NewWorldOfDarkness'' have an ability to heal injuries faster by spending their {{Mana}}:
** Werewolves in both ''TabletopGame/WerewolfTheApocalypse'' and ''TabletopGame/WerewolfTheForsaken'' have an accelerated healing factor: not only can they spend Essence to heal lethal damages, but bashing damages heal each turn for free. The later game, ''Werewolf: the Forsaken'', actually plays up the cancer element; if a werewolf's wounded with silver, there's a chance they could develop a malignant growth not entirely unlike cancer. 2e Forsaken got this ability upgraded; their healing powers mean that they can effectively NoSell the ChunkySalsaRule, as they can no longer suffer Aggravated level damage from any source other than silver weapons, supernatural attacks, or completely filling out their health bar with Lethal damage. Also, being in War-Form means they immediately heal ''all'' non-Aggravated damage at the start of every turn, making them one of the setting's candidates for being {{Nigh Invulnerab|ility}}le.
*** One of the fomori powers in ''TabletopGame/WerewolfTheApocalypse'' provides this, except that every time you regrow something, you get nasty scars and often malignant tumors as well. Being a fomor is completely disgusting, seriously.
** Vampires in both ''TabletopGame/VampireTheMasquerade'' and ''TabletopGame/VampireTheRequiem'' can heal about as quickly as Werewolves, but they must expend blood they've ingested to do so, and the strength of their healing factor depends on the damage type. "Bashing" damage [[note]]basic bruises and sprains, the sort of things a human would get from a dust-up[[/note]] heals faster than "lethal" damage[[note]]serious injuries, equivalent to humans being cut or shot[[/note]]. Damage from fire, sunlight or a supernatural source, "aggravated damage", takes even more blood and time to heal. Depending on game and edition, different kinds of attacks are assigned different levels of lethality -- for example, in the original version of ''Requiem'', gunshots were considered to only do bashing damage, while swords and the like still did lethal. Perhaps realizing that this didn't make a lot of sense, the UpdatedRerelease, "Blood & Shadow", instead made it that all sources of lethal damage are instead downgraded to bashing damage, thus emphasizing how dangerous fighting a vampire with a conventional weapon is.
** Mage in ''TabletopGame/MageTheAwakening'' can spend {{Mana}} to heal lethal or bashing damages instantly, but it's much more expansive than for werewolves and vampires, requiring three points of mana to heal either one bashing damage or one lethal damage.
** Beasts from ''TabletopGame/BeastThePrimordial'' have one of the strongest healing factor with werewolves, as they can spend one point of Satiety to heal ''all'' bashing damages, three lethal or one aggravated. As a drawback however, they can only trigger it while [[HomefieldAdvantage inside their Lair]].
* This is the [[PlanetOfHats Hat]] of the [[OmnicidalManiac Necrons]] of ''TabletopGame/{{Warhammer 40000}}''.
** Well one of them, their primary [[PlanetOfHats Hat]] is that they are hyper-advanced robots.
** To a lesser degree this applies to the Orks, who are capable of healing from any non-fatal wound quite quickly, and when you consider how "tuff" they are, a fatal blow is difficult. In fact, standard Imperial procedure is, after a battle with Orks, to go around and cut the heads off their bodies with entrenching shovels to make sure they stay dead. About the only non-fatal thing that they can't regenerate on their own is severed limbs and they can still stitch the lost limb, or even someone else's limb, back onto the stump and have it heal together pretty quickly. They can even reattach severed '''heads''' and walk off like nothing happened!
*** It's been hinted at least once that they were genetically engineered as a self-perpetuating species of {{Super Soldier}}s by [[ThePrecursors The Old Ones]], which would partially justify this, as does the details on their BizarreAlienBiology (for example, there's a kind of fungus living in their skin/bloodstream that clots up wounds almost instantly).
** With a bit of help from [[TheCorruption mutation]], Tellos of the Soul Drinkers picks up this ability. It gets to the point where he can run into battle ''naked from the waist up'' without suffering meaningful damage. It doesn't help with injuries from before he gained this ability - so he can't regrow his hands - but that's not much of a problem when you have {{chainsaw|Good}}s attached to your wrists. [[spoiler: It takes ''[[EarthShatteringKaboom Exterminatus]]'' to kill him in the end.]]
*** The Carnifex is even tougher. One of them ''survived Exterminatus. On the planet's surface''. When they found it, they had to call in a heavy-duty orbital bombardment to finish it off.
* ''TabletopGame/MagicTheGathering'' has various spells and abilities that allow creatures to regenerate instead of going to the graveyard, wiping out all damage they may have suffered in the process (as well as tapping them and taking them out of combat). These usually require some cost to be paid (usually in mana) and there are forms of destruction that explicitly cannot be regenerated from... -- Creatures also recover from damage that fails to kill them pretty quickly by default, as 'remove all leftover damage from stuff still in play' is one of the automatic events of the last step of each turn. (''Players'' aren't so lucky.)
* Lunar Exalts in ''TabletopGame/{{Exalted}}'' are stated as being able to recover from terrible injuries at an astounding rate whilst in their warform, if not in battle (they must use separate healing powers for that purpose). They can regenerate lost limbs and internal organs (assuming they aren't dead) at a rate of one such organ or limb ''per hour'', good as new and fully functional.
* Regeneration in ''TabletopGame/{{GURPS}}'' ranges from slow enough that people would have to hang out with you for a while to notice it all the way to so fast that you heal your total HP every second.
* ''TabletopGame/{{Warhammer}}''
** Regeneration is a game effect common enough to be in the main rulebook rather than the army specific ones and is cancelled by fire.
** The game featured a hero called Valtan as part of their Storm of Chaos event who, by reason of being probably the avatar of a god, had a healing factor good enough that there was a 5 in 6 chance of him surviving any attack that took his last wound with no ill-effects, hopping back to his feet to fight again. In certain corners he became known as yo-yo Valtan.
** Trolls have a chance to recover any wound taken that turn, unless hit by fire. The goblin chieftain Gromm the Paunch got his name by winning an eating competition with raw troll steaks. The flesh perpetually tries to grow, mostly kept in check by his stomach acids. Ever since he's been troubled by huge digestive problems, although on the plus side he eventually gained regenerative abilities.
* In ''TabletopGame/EclipsePhase'' anyone with basic biomods heals twice as fast as a baseline human (regain HP every 12 hours instead of 24), even slowly regrowing limbs. [[NanoMachines Medichines]] can speed that up an additional 12 times (every hour).
* ''TabletopGame/CallOfCthulhu''. Several monsters and deities could regenerate their injuries at high speed: Chthonians (1-5 HitPoints per round depending on age) Cthulhu (6 HitPoints per round), Hounds of Tindalos (4 HitPoints per round) Shoggoths (2 HitPoints per round), Shudde M'ell (5 HitPoints per round), Star Spawn of Cthulhu (3 HitPoints). Tsathoggua regenerates a stunning 30 HitPoints per round.
* ''TabletopGame/HollowEarthExpedition'' has several versions of this.
** All creatures inside the Hollow Earth heal at twice the normal rate. People have gone to sleep severely injured and woken up completely healed.
** Anyone with the Quick Healer talent heals at twice the normal rate. This benefit is cumulative with the Hollow Earth healing bonus above, for a total benefit of healing at four times the normal rate.
** Lizardmen can regenerate damaged organs and lost limbs. A finger takes a week, an eye or other small organ in two weeks, and a tail, arm or leg in five weeks. This benefit is cumulative with the above examples.
** Inhabitants of Shangri-La heal at four times the rate of the surface world, and anyone who spends a year there will have lost limbs begin to regenerate and birth defects disappear.
* ''It Came from the Late, Late Show''. Monsters with the Regeneration special ability can recover lost Survival Points (HitPoints) at an accelerated rate depending on the type of Monster.
* Chaosium's supplement ''All the Worlds' Monsters'' Volume III
** The Amphisbaena (a giant snake with a head at each end of its body) recovers four lost HitPoints per melee turn.
** Balitorr, King of the Earth Elementals, can regenerate five HitPoints per melee turn.
** Chakarra, Lord of Fire, can heal five HitPoints per melee turn.
** The 6th level Basic Demon can restore 1 HitPoint of damage per HitPoint of damage it inflicts on other creatures.
** The Rainbow Demon is a GiantSpider with nine attacks per melee turn. For each attack it doesn't make during a melee turn it regenerates 20 lost HitPoints.
** Dark Elves regain 1 HitPoint of damage per melee round.
** Etheran, Lord of the Air, is King of the Air Elementals. He heals five HitPoints per melee turn.
** A Gnome of Yipuuri spends his time wandering around cleaning up and re-stocking dungeons after {{PC}} parties are done with them. If attacked by adventurers he can heal six HitPoints per melee turn.
** Klithgor the Destroyer is the lord of all ghosts, spirits and nightshades. He can regenerate ten HitPoints and 1-6 lost levels of LifeEnergy per melee turn.
** A Morq is an android with no facial features and large ears. It gains back 3 HitPoints per melee turn, starting three melee turns after being damaged.
** The Murkworm is a huge worm that is 60-90 feet long. It recovers 1 lost HitPoint per melee turn.
** The None Such is a cross between a blink dog, a Greater Demon and a phase spider. It can heal four HitPoints per melee turn.
** Nunoria, Lord of Water, is the king of the Water Elementals. He can restore 5 HitPoints of damage per melee turn.
** The Ogron is a large humanoid with an incredibly ugly face. He can regenerate 1 HitPoint each ten minutes.
** A Shock Troll heals five HitPoints per melee turn.
** The Great Wraith can regenerate 3 HitPoints per melee turn.
** The Yarzooyn is a large [[MultiarmedAndDangerous six-armed]] humanoid that regains six lost HitPoints per melee turn.
* ''Arduin'' RPG, ''The Compleat Arduin Book 2: Resources''
** Greater Demons
*** Nagandas, Lord of the Sea Serpents, regenerates 6 HitPoints of normal damage per melee round. He also regains 1 point of lost Strength, Constitution or LifeEnergy level once per minute to a maximum of 18 points per day.
*** The Nameless One (or The Unbeckoned) will heal any damage done to it at a rate of ten HitPoints per melee round.
*** Shuggondra the Bloated One is a BlobMonster: a huge white mass of squirming, quivering translucent flesh with various protuberances (pods, nodules, tentacles etc.). Any damage it takes is healed at a rate of 8 HitPoints per melee round.
*** Vorcas Hell Jaws can regenerate damage at a rate of 6 HitPoints per melee round. He can also regain up to 20 lost points each of Strength and Constitution per day at a rate of one point per round.
** Angelic beings (angels, maruts, etc.) heal five HitPoints per melee round.
* ''TabletopGame/HeroSystem'' supplement ''Fantasy Hero Companion''. Demon lords can regenerate 4 Body (HitPoints) per turn (12 seconds).
* In ''TabletopGame/PsionicsTheNextStageInHumanEvolution'' espers with the biofeedback power can heal themselves from life-threatening wounds in seconds with the Regeneration talent.
** Espers with a high enough strength score can heal from grievous bodily harm in a matter of days.
* In ''TabletopGame/HcSvntDracones'' reptilian characters can take genetic reclamation surgery to gain the ability to regenerate lost limbs. But it doesn't speed up HP recovery at all and actually requires full HP to work.
* In ''TabletopGame/{{Ironclaw}}'' the "Reserves of Vitality" atavism allows a character to remove a "Hurt" status effect once per day, it can't do anything about "Injured" though.

[[folder:Video Games]]
* Pretty much every character in ''VideoGame/{{Borderlands}}'' and ''VideoGame/{{Borderlands 2}}'' can invest into skills granting health-points regeneration (the games feature shields, that can withstand large amount of damage, but they eventually fail and there are attacks that deplete shields at alerting speed). Also, there are items, bestowing such quality onto their wielder, and many skills restore some amount of health-points and shields on activation (usually after killing an enemy). Health-restoring items are a rare drop in-games and occupy limited space in inventory, so it is easier to rely on natural regeneration.
* The Nameless One in ''VideoGame/PlanescapeTorment''. In gameplay terms, this results in speedy regeneration of lost hit points. Also, some tasks take full advantage of this ability, requiring that you cut out various body parts and use them for some purpose probably not in the human body's user manual.
** The healing factor is such that The Nameless One can spontaneously come back from the dead, too - there are a few quests in which 'killing' yourself is a valid solution.
** His healing factor isn't perfect -- there's a reason he's covered head to toe in scar tissue. His body is so ruined that items that normally only repair the undead can work on him.
* Vito of ''VideoGame/MafiaII'' can shrug off and recover from bullet wounds that would leave his mobster companions cringing in pain [[CutsceneIncompetence (in cutscenes, at least)]]
-->'''Joe:''' He's a doctor, deals a lot with people in our line of work. You shouldn't need to see him though, Vito, you always [[LampshadeHanging seem to heal quick enough]]. [[HandWave Must be your diet]].
* In ''VideoGame/CityOfHeroes'', the "Regeneration" powerset emulates this.
** With a bit of creative tinkering, it was possible to create a Regen Scrapper that was essentially {{Nigh Invulnerab|ility}}le to attack from enemies ten levels higher and more... in a game where a four level gap was considered impossible for anything less than a full team. Suffice to say, the developers nerfed this ability no less than four times in a row.\\
This is also why, in a game where numerous characters are disproportionately powerful in battles of attrition, and hit-run-and-repeat tactics are intentionally left viable, there are still things which take a group to bring down - their intrinsic combat regeneration is just too strong to overcome by anybody who can indefinitely survive their assault.
* The Wood Golems in the ''Franchise/{{Disgaea}}'' series have this as their passive ability, which regenerates 20% of their HP each turn. They can also pass this onto another unit by becoming a Magichange weapon for them.
* White Mages in ''VideoGame/FinalFantasyXI'' have a version of this, when at level 25, they get Auto-Regen, which constantly restores 1 HP every 3 seconds (at level 76 this increases to 2 HP every three seconds). If they don't get hit after getting hurt and stand still for(At most) an hour, they can go from near-dead to full HP, so this trope does count.
** Rune Fencers get no Healing Magic of any kind. ''They don't need it.'' A master-level Rune Fencer can cast Regen IV to last 93 seconds, restoring 30 HP every three seconds--on top of their 3HP/tick Auto Regen and any bonuses to Regen from their equipment--and if he ''still'' needs a little pick-me-up, he can use Vivacious Pulse once every minute to recover HP based on his stats and the runes he's using--for no MP cost. Ninjas tank by not getting hit, Paladins tank by not getting hurt, and Rune Fencers tank by [[Main/NoSell not ''staying'' hurt.]][[note]]Well, that and having the highest Parrying skill, using abilities to capitalize on that, possessing above-average Evasion, being able to stack slightly more physical damage reduction than Paladins, and ''eating magic.''[[/note]]
** Most of the ''Franchise/FinalFantasy'' games have a similar Regen spell, most of which restore a set percentage of HP each turn, while the one in ''VideoGame/FinalFantasyVII'' restored HP constantly. If combined with a Haste effect, attacks that hit for less than 500 or so HP wouldn't even register on the status bar.
** Speaking of which, a popular fan-theory states that people who have been infused with mako, such as the members of [[SuperSoldier SOLDIER]], have this. Nowhere near {{Wolverine}} levels, but just enough to [[MadeOfIron endure injuries that would incapacitate an average person]]. It would explain how Cloud managed to get back to his feet after getting [[ImpaledWithExtremePrejudice shish kabob-ed]] in ''Advent Children Complete''.
* ''VideoGame/DevilMayCry'' - The potent-or-not Healing Factors of Dante and Vergil constitute one of the series' more annoying CutscenePowerToTheMax moments.
* X gets it in ''VideoGame/MegaManX3'' when he gets either the enhanced helmet or the [[InfinityPlusOneSword Golden Armor]].
* ''VideoGame/{{Persona 3}}'': [[ElegantGothicLolita Chidori]]'s persona, Media, grants her a passive ability called ''Spring of Life'', which restores her health at a somewhat alarming rate, both in and out of combat. [[spoiler: She later gives this ability to Junpei to save his life, and sacrificing hers.]]
* ''VideoGame/TeamFortress2'':
** The Medic class has innate regeneration. Although a class designed to heal others, the Medic can also heal from any damage back to full health, which is good when you consider that he can't turn his medigun on himself. If the Medic goes a certain amount of time without getting hurt again, he regenerates faster. In total, it takes less than half a minute to regenerate to full health, even from the last hitpoint. Equipping the [[LifeDrain Blutsauger]] reduces his regeneration speed, while equipping the Amputator will increase his regeneration speed instead.
** An item for the Sniper, the Cozy Camper, gives the Sniper a small trickle of health every second, and so will require roughly 2 minutes to heal from one hitpoint back to full health. However, using this regeneration item denies the Sniper any other secondary weapons, and it makes him take more damage from enemy attacks besides.
** After a patch, the Soldier can get in on the fun now too. The Concheror provides +2 health every second, and when charged grants LifeDrain to allies attacks.
* In ''VideoGame/{{Terraria}}'', all Non-Hostile [=NPCs=] and the Player regenerate health slowly over time. In the case of the [=NPCs=], it's a fixed regeneration rate. In the case of the Player, his regeneration rate depends on how long it's been since his last hit, starting off at almost no regeneration at all and going up to about 10 HP per second. The regeneration rate doubles while standing still. There's also an accessory that gives its own form of regeneration that isn't effected by the factors that limit the natural regeneration and steadily restores 1 HP every 2 seconds regardless of situation. Campfires, Honey (Pool of it), and Heart Lamps also provide regeneration within a certain radius.
* Trolls in the ''VideoGame/{{Warcraft}}'' universe have a healing factor known as Troll Regeneration. They can regenerate limbs unless fire, magic is used or if they angered their loa gods. In-game, this translates to regaining lost HP points without the aid of healers or potions. (in World of Warcraft ''everyone'' regains HP in this manner, but Trolls do it ''faster'') and are the only ones tha can do it while in combat.
** It's also very, very weak and the butt of several jokes about its insignificance. In a game where characters have tens of thousands of HitPoints: "I'm regenerating 5 health per second and there's nothing you can do about it!"
*** The Warrior class actually has several abilities and talents that perform exactly this; while other classes can heal with magic, warriors (and druids that use the same rage mechanic) are the only class that can heal grievous wounds with [[HulkSmash anger]]. Unlike the troll racial ability, they can return from the brink of death to greater than half health in mere seconds if left unmolested.
*** Blizzard [[CriticalResearchFailure actually forgot]] trolls had this ability (along with many other things) in the trailer for the [[ScrappyLevel subpar instance]] Zul'aman. For those confused, in the trailer, a troll cuts off his arm with a regular broken spear and it doesn't grow back.
*** This was handwaved later as Troll's needing to "be in balance with the loa (nature spirits) of their tribe" in order to heal, with the amount of favor a troll has been given by the loa proportional to how fast they can heal, meaning a troll that has fallen out of balance/favor with the loa (such as Zul'Jin apparently) will be unable to heal missing limbs, or if they ''really'' piss them off, unable to heal from even a paper cut.
*** Further elaborated on in Vol'jin's short story, where he cuts off his broken thumb so that it will regenerate instead of heal improperly. The narration mentions that amputated digits are about the limit of what the average troll is able to regenerate and that entire limbs and complex organs are beyond what all but the most extraordinary trolls are capable of. Zul'jin's eye and arm were left to heal about as well as a human would for this reason, but there are tales of a legendary troll so attuned to the loa that he was able to regenerate completely after having most of his body burnt to ashes.
** In ''Warcraft 3'', you have to [[YouHaveResearchedBreathing research]] the ability if you want your Trolls to regenerate faster. Even then, it has about no effect during a battle, though it does help to save on Healing Salves after the battle.
* The final boss in ''VideoGame/SeriousSam: The First Encounter'', Ugh-Zan the Third, is a towering behemoth who is nearly impossible to kill thanks to his regeneration abilities. To kill him, a player will have to wear him down first with his own weaponry before activating an enormous death ray to finish him off before he can trigger his healing ability.
* Albedo, one of the antagonists of ''VideoGame/{{Xenosaga}}'', has this ability to the level that makes him immortal. This is in fact why he is [[spoiler:so AxCrazy in the first place. His fear of losing Rubedo, and all those close to him, to death while not being able to die himself, drove him insane. Now he seeks just that, [[WhoWantsToLiveForever ending his own life]]]].
* The main character in ''VideoGame/ShadowOfTheColossus'' doesn't have much in his favor, but it helps that he can take a crushing blow from a Godzilla-sized hulking monstrosity, get pounded into the dust, and as long as he's still alive he'll shake it off in a minute or two.
* In ''Franchise/MassEffect'', this rapid healing is one of the abilities of the Soldier class, as well as the Krogan Battlemaster class.
** It's a racial ability for both vorcha and krogan in the ''Franchise/MassEffect'' universe -- the former because of their unique cell structures, the latter due to very resilient physiologies that include secondary and sometimes even tertiary organ systems (for a start, they have fully redundant nervous systems). In VideoGame/MassEffect2, in fact, they will heal from brink of death to full health in seconds unless you hit them with an Incinerate or Warp power, or shoot them with Incendiary (and possibly Warp) Ammo.
** This is arguably the entire point of the vorcha multiplayer characters in ''VideoGame/MassEffect3''. Their Bloodlust ability causes their health regeneration to not only skyrocket, but also to ignore the game's usual rule about avoiding damage for a few seconds to trigger regeneration; they can be getting sprayed with assault rifle fire and keep regenerating between bullets. Despite having pathetically weak shields, this health regeneration is enough to make the vorcha nigh-unkillable by commons {{Mooks}} like Assault Troopers or Cannibals.
* The ''VideoGame/{{Touhou}}'' series features [[{{Immortality}} Kaguya Houraisan]] and [[WhoWantsToLiveForever Fujiwara no Mokou]] whose healing factors are derived from the Hourai Elixir, the Elixir of Immortality. Theirs is a Type IV immortality; they can resurrect from total bodily destruction, feeling [[FateWorseThanDeath every little thing along the way]] and, as suspected, getting used to it. The only way the protagonists can fight Mokou in an otherwise safe duel in the Extra stage is by attacking her for lethal durations and repeatedly killing her until she is ''too tired''.
-->'''Marisa:''' Shall we do it again? Maybe you really are invincible.
-->'''Alice:''' Invincible, maybe, but she seems worn out.
-->'''Mokou:''' I've already reached my limit. I'd better stop before I'm unable to move tomorrow.
-->'''Alice:''' So, muscular pain only, eh?
** Also, [[OurVampiresAreDifferent Remilia]] [[{{Ojou}} Scarlet]] has been [[InformedAbility stated]] to be able to regenerate indefinitely so long as at least [[FromASingleCell ''something'']] remains of her being, such as a ''piece of bat flesh''. [[InformedAbility Though we never actually see her regenerate from an apparent death,]] we ''are'' treated firsthand to her ability to '''infinitely spawn bats from herself''', ALL of which are fair game for her healing factor. Essentially, unless you make extremely sure there's no trace of her left ''at all'', she's nigh unkillable.
** ''Ten Desires'' brings us Yoshika Miyako, a {{Jiangshi}} with the "ability to eat anything and everything", who uses this ability in-game to restore her health by absorbing spirits. This can make her first and third spellcards, the ones that make use of this ability, annoying to capture, as for the first you have to refrain from shooting down the bullet-shooting [[FlunkyBoss enemies]] Yoshika produces, and for the third card, you must weave through her bullets and slip past lasers to get close to the boss when she summons a bunch of blue spirits, so you can collect them before she does.
* A FirstPersonShooter (as well as other shooters) trend has been to apply this trope to the main character. It doesn't matter how many bullets have pierced your body in total over the course of the adventure: As long as you can find some cover to hide behind for a few seconds before this particular batch of bullets kill you, you're fit for fight again.
** Nathan Drake from the ''VideoGame/{{Uncharted}}'' series is thus able to run around punching gun-wielding mercenaries to death, as long as he can dart in and out of cover.
*** Developers handwaved this particular aspect of Drake as his health not actually representing his well being, but rather his (incredible) luck. The idea here is that Nate is effectively pushing his luck the longer he stands in the line of fire, and there is a point at which fate gives up on him and lets him die.
** Similarly, Marcus Fenix of ''VideoGame/GearsOfWar'' runs around without a helmet because this trope allows him to. Ironically, other characters ''wearing'' helmets are prone to headshots.
* In ''VideoGame/DragonQuestIII'', several of the bosses have healing factors, sometimes as much as 100 HP per round. It's especially nasty because this happens behind the scenes, and the player is given no indication of it.
* One of the player character's augmentations in ''VideoGame/DeusEx'' is Regeneration, this requires power to use.
** VideoGame/DeusExHumanRevolution features a healing augmentation that can restore you to full health in a few minutes, balanced by the fact it takes a few seconds to kick in and your character is more fragile.
* In ''VideoGame/{{Prototype}}'', Mercer can heal over time when not under attack. It's faster to [[ImAHumanitarian eat people]] though. Alex tanked alot of gun shoot wounds from Blackwatch and the holes in his body were instantly healed.
** ''VideoGame/{{Prototype 2}}'' reboots this whole mechanic with 4 levels of regeneration upgrades, from healing up to 50% of max health while not in alert, to recovering fully even in combat as long as no damage is incurred for a certain amount of time. Additionally, a Radnet mutation allows slow but constant regeneration as long as the shields are active, on top of whatever regeneration upgrades already present.
* Several ''Franchise/{{Pokemon}}'' abilities and moves do this, such as ''Recover'' or ''Rain Dish'' (when it's raining). The "Leftovers" item gives a Regen-like effect, while the ''Poison Heal'' ability grants it when the Pokemon is "suffering" from [[StandardStatusEffects poison]]. Introduced as an ability in its own right in Generation V, where Pokémon regenerate a small amount of health when recalled.
** Many Pokédex entries give certain Pokémon this ability. [[GameplayAndStorySegregation This doesn't affect the game.]]
* ''VideoGame/TheDungeonOfDoom'' lets you accelerate healing by slipping on a regeneration ring. Just make sure it isn't one of those [[StuckItems unremovable]] ''negative'' regeneration rings...
* Expect [[StarfishAliens Xenomorphs]] in any Franchise/AlienVsPredator game to have regen abilities. It can be accelerated with a quick headbite. It ties into the mythos; Xeno's are adapted to be the perfect survivors. In the (unfortunately extremely rare) RTS, human [[AbnormalAmmo Radiological Ammo]] stops it.
* Elena from ''VideoGame/StreetFighterIII'' has a super move that allows her to regenerate up to one-third of her health.
* ''VideoGame/{{Fallout 3}}'' features a very slow healing factor in the form of the ''Solar Powered'' perk. As you would expect you need to be in direct sunlight for it to work. Another perk (''Rad Regeneration'') allows you to heal limb damage but not overall health so long as you have Advanced Radiation Sickness. Other Fallout games have a 'healing rate' which works in the standard way. There is also a hidden 'microregen' rate (natural healing) in the code that was 'inherited' from ''VideoGame/TheElderScrollsIVOblivion'', this restores health very very slowly.
** All of the games also had the ''Fast Metabolism'' perk, which is ExactlyWhatItSaysOnTheTin; you have a HyperactiveMetabolism that increases your natural healing rate significantly (''VideoGame/{{Fallout|1}}'', ''VideoGame/{{Fallout 2}}'', ''VideoGame/{{Fallout Tactics|BrotherhoodOfSteel}}''), or increases the effect Stimpaks have on you to make you regenerate faster (''Fallout 3'' and ''VideoGame/FalloutNewVegas''). The problem is, it also makes you much more vulnerable to damage from poisons and radiation!
** ''VideoGame/FalloutNewVegas'' allows you to purchase the "Phoenix Monocyte Breeder" implant for 12000 caps. Once implanted, this implants allows you to regenerate 1 HitPoint every 10 seconds. While this rate of healing makes no difference during battle, it saves some cash and stimpacks in the long run.
* ''VideoGame/{{Stalker}}'''s main character has a slow healing factor, assuming you don't bleed to death first...
** The mechanic is closer to GradualRegeneration, with some HealThyself and HyperactiveMetabolism thrown in if the player needs health more quickly. However, the right combination of high-level artifacts can bring this much closer to a super-human Healing Factor level, just beware the possible side effects...
* In the ''VideoGame/BioShock'' series, the Little Sisters personify this trope; because of the huge amounts of AppliedPhlebotinum coursing through their veins, they can reconstruct their bodies instantly. In fact, they heal so fast that they frolic around with no suits at the bottom of the ocean. They heal so fast that their skeletal structure reconstructs itself 'before they explode from pressure.' However, ''VideoGame/{{BioShock 2}}'' reveals that it's not all that it's cracked up to be. According to one Audio Diary, when a Little Sister fell off some railings, her leg bones regenerated in odd angles, forcing doctors to break her legs until it healed right. The diary ends with the doctor saying that although they may heal, he can confirm that they feel pain.
* Two games have a water based healing factor, ''VideoGame/BioShock2'' has the Fountain of Youth gene tonic and ''VideoGame/GiantsCitizenKabuto'' has it as Delphi's natural sea reaper trait.
* ''Franchise/{{Metroid}}'' - Ridley [[ImAHumanitarian devours his enemies]] to repair wounds. Aside from cloning/cybernetics, no one really knows how he [[NoOneCouldSurviveThat reappeared after being tossed down a kilometers-long shaft or being completely disintegrated.]] ''VideoGame/MetroidOtherM'' states that [[spoiler:''VideoGame/SuperMetroid'' is the only ''true'' death of Ridley. This means that chronologically, he has survived every prior death due to his regenerative abilities. The two games that come after involve an unintentional clone and an X parasite infesting the corpse of said clone]].
* Vamp in the ''Franchise/MetalGear'' series has the ability to recover from apparently-fatal injuries (including multiple stabbings and headshots) after the Patriots used him as a guinea-pig to test an experimental strain of nanomachines.
** In ''VideoGame/MetalGearRisingRevengeance'', Raiden can instantly heal all damage through ''Zandatsu'', cutting open enemy cyborgs and [=UGs=] and crushing their nanorepair modules.
* ''VideoGame/RivieraThePromisedLand'' has Ledah, who regenerates HP every turn, as a temporary playable character during the prologue, making it seems impossible for you to get a game over even though the protagonist keeps dying again and again.
* In ''VideoGame/ValkyriaChronicles'', Alicia has a potential called "Mysterious Body." Apparently, ever since she was a little girl, her wounds were always very quick to heal. This comes from her power as a Valkyria, but is never explained from a practical standpoint. However, despite her gunshot wounds healing rapidly, she needs Welkin's knowledge of herbs for a [[TwistedAnkle sprained ankle]].
* ''RogueSquadron'': Ships equipped with an astromech droid will gradually regain health as the droid makes repairs. However, if your droid is destroyed you lose this ability.
* An incredibly disgusting version is used by [[spoiler:the Hunter]] in ''VideoGame/DeadSpace'' who [[spoiler: regrows entire limbs]] while flailing and oozing. Where it gets the extra tissue required is [[ShapeshifterBaggage unknown.]]
* ''{{Starcraft}}'''s Zerg have a healing factor, which shows up in-game as their units (and [[OrganicTechnology buildings]]) being the only ones to regenerate HitPoints over time. Roaches in particular can go from near-death to full within seconds when burrowed.
* In ''VideoGame/GhostTrick'', [[spoiler: Yomiel has a fragment of the Temsik meteor lodged in his body that constantly restores his body to how it was just before his death]].
* Fittingly, [[LizardFolk shra]] in ''VideoGame/TheReconstruction'' have very high rates of bodily regeneration, though not to the extent of most Healing Factors. This is [[{{Deconstruction}} deconstructed]] with Skint (who ''does'' have a very potent Healing Factor), who got stabbed in the back with a large sword...and his body healed the wound, ''with the sword still in''. To make things worse, the sword was lodged through his heart, making it impossible to take out without killing him. It also means he can [[TwentyFourHourArmor never take off his armour]], which must make sleeping pretty difficult, too.
** Qualstio's final passive skill, Physidrawing, gives him high regeneration rates as well (in gameplay terms); it is not as strong as the bodily regeneration of the shra, but regenerates [[SoulAnatomy all his]] [[MultipleLifeBars gauges]] quickly. Plus, being intrinsic regeneration, it's still stackable with regeneration buffs.
* Many bosses in ''VideoGame/SuperRobotWars'' not only have HP regeneration, but also ''completely'' heal themselves when you defeat or successfully reduce their HP to certain amounts. Some endgame bosses tend to go so far as doing this ''three'' times.
** Bosses aren't the only ones with healing factors. Major late-game units tend to have HP Regen. The worst of the bunch is the manga version of Anime/{{Mazinkaiser}}, whose major armor goes hand-in-hand with its high level regeneration, making him a tough nut to crack.
* The Stranger of ''VideoGame/OddworldStrangersWrath'' can shake the pain away.
* One of the effects of the Mantle skill in ''VideoGame/FireEmblem: [[VideoGame/FireEmblemTellius Radiant Dawn]]'' is regenerating an amount of HP equal to Luck at the beginning of each turn. All the enemies with this skill have maxed Luck... The [[http://fireemblem.wikia.com/wiki/Imbue Imbue]] and [[http://fireemblem.wikia.com/wiki/Renewal Renewal]] skills also allow the holder to regain HP at the beginning of their turn, but contrary to Mantle they are not specific to one unit since the game mechanics allow skills to be traded between units. The Black Knight also has the Imbue skills, which cannot be removed from him.
** In ''VideoGame/FireEmblemAwakening'' and ''VideoGame/FireEmblemFates'', Renewal is a skill exclusive to War Monks/Clerics (Awakening) who reach level 15 (''Awakening'') and Priestesses/Great Masters who get to level 5 (''Fates''). Any character with access to such class trees can potentially reclass into it and get it, [[spoiler: and the children of a one of them can inherit it from his/her parent]].
* The ''VideoGame/LostOdyssey'' characters have something more like this kind of immortality in actual gameplay; they can be injured and knocked out in battle, but automatically revive after a couple of turns.
* In ''VideoGame/ChaosRings'' and ''VideoGame/ChaosRingsOmega'', the winning BattleCouple is granted immortality that regenerates any injury short of vital organ removal and special telomeres that [[TheAgeless halt the aging process]]. It comes with a 10,000 year time limit though [[spoiler:just in time for the next Ark Arena]].
* The Primagen in ''VideoGame/{{Turok}} 2: Seeds of Evil'' can regenerate lost body parts and HP, and to stop it you must shoot him repeatedly in the head while he's in the process.
* In ''VideoGame/{{Syndicate}}'' (2012) this is explicitly Agent Crane's main power. He has three "blocks" of health and will regenerate to the limit of the current block if you fail to damage him enough in one go.
* A number of viruses in the ''VideoGame/MegaManBattleNetwork'' series regenerate their HP at a varying rate when damaged, the N.O. virus in the the third game being the most extreme example, maxing out its HP in a few seconds regardless of the damage incurred (A fact it exploits by using itself as a living shield). All wood element viruses and navis will also rapidly regain HP while standing on grass.
* ''Franchise/ResidentEvil'':
** In ''VideoGame/ResidentEvil2'', William Birkin gets a healing factor after mutating due to injecting himself with the G-Virus. This causes his body to undergo further, more horrific mutations whenever he sustains injuries. However, it isn't perfect: after nearly getting done in in his fourth form, his healing factor fucks up and fails to properly heal his wounds, turning him into a grotesque and disgusting blob of flesh.
** Regenerators in ''VideoGame/ResidentEvil4'' can regenerate lost body parts, but will die if you deal enough raw damage to them or kill all of the parasites inside their bodies.
** In ''VideoGame/ResidentEvil6'', [[spoiler:Sherry Birkin]] is revealed to have one after [[spoiler:the G-virus in her body mutated when she received the vaccine]].
** Likewise in ''VideoGame/ResidentEvil6'', you find out at the absolute ''worst'' possible time that [[ImplacableMan Ustanak]] has one as well. Unlike other C-Virus infectees who mutate insect-like parts, Ustanak simply heals due to a genetic abnormality. [[spoiler:He shows up fully healed about five minutes after taking a ''mining drill'' through the chest and [[CurbStompBattle beats Sherry and Jake down]] so the J'avo can capture them.]]
* ''VideoGame/LeagueOfLegends'' has Dr. Mundo, whose passive regenerates a small portion (.4%) of his maximum health every 4 seconds. That may not seem like a lot, but Mundo is encouraged to build items that increase his maximum health, which increases his health regeneration. His Ultimate kicks this into overdrive by letting him regenerate back ''up to 60% of his maximum health.'' A Mundo at his full build with his ultimate available is considered to be on of the hardest enemies to kill in the entire game.
** To add to this, Garen gains extra Health Regen after 9 seconds of not being struck by a jungle monster or enemy champion (enemy minions don't reset the timer). Morgana has Spell Vamp, meaning a percent of damage she does with her abilities is given to her as health. Nasus has Life Steal, meaning a percent of damage from regular attacks is given to him as health. To compound this, everyone can build items that grants them Life Steal or Spell Vamp (Life Steal is far more common), and Warmog's Armor even grants a Passive similar to Mundo's (regenerate an extra 1% of health) while also adding a flat 1000 health to your max.
* The boss Beef Cloud in ''VideoGame/MarioAndLuigiDreamTeam'' is all about this gimmick. In fact, he doesn't actually attack at all, the whole 'difficulty' of the battle is that he heals a significant amount of health every two seconds or so, meaning you have to hit him more quickly than he can recover.
** For that matter, many of the later bosses have this sort of health recovery anyway. The final boss for instance can jump into the background, then recover 200 HP per turn until you defeat his mooks in the foreground. And Pi'illodium can restore a fairly high amount of health on a regular basis if you don't get rid of those flunkies he summons every two turns or so.
* In ''VideoGame/BaldursGate'', if a character has a constitution of at least 20, they gain a healing factor, allowing them to regenerate to full health within several (in-game) hours.
* A variation of this comes up in ''VideoGame/AssassinsCreed'': since the player is actually just reliving the memories of the characters in the main setting of each game, they technically don't suffer from any injuries that the character doesn't receive as an example of GameplayAndStorySegregation, such as [[VideoGame/AssassinsCreedIII Connor]] being visibly affected by injuries received from a near miss by a cannonball in a cutscene which hinders his movement. In normal gameplay, however, injuries are never as staggering even though they ''can'' lead to death in-game. This Healing Factor is partly justified by the framing device of the game: health actually indicates how well-synchronized the player is to how the character behaved historically, with loss of all their health resulting in a game over via death because the character did not die at that point in their lives.
* Players in ''VideoGame/{{Ryzom}}'' heal whatever injuries they had automatically, and do so at an accelerated rate when they're sitting down, regardless of whether they were mauled by an enormous crab or thrashed by a particularly virulent magic spell.
* ''VideoGame/TheElderScrollsVSkyrim'': All NPC's and the player heal slowly in combat and slightly faster out of combat, with some potions and enchantments increasing this rate. Argonians can increase this by ten times once a day. The only exceptions are werewolves in wolf form and vampires in sunlight.
* In ''VideoGame/CivilizationBeyondEarth'', this is what makes Harmony affinity units camping in Miasma tiles so powerful. High-tier Harmony units are bristling with some pretty thorough biological augmentations and can often heal quickly through the damage inflicted on them. In the ''Rising Tide'' expansion, the Immortal unit exclusive to the Harmony-Purity hybrid affinity are genetically augmented humans who can heal 23HP per turn, the highest amount of any unit in the game.
* [[PowerTattoo Nexus Champions]] and [[AscendedDemon Redeemed]] in ''[[NexusWar Nexus Clash]]'' get a pretty powerful healing factor to stay alive in the series' endless apocalyptic war. In the case of the Redeemed, it's because they're TheAtoner and are ''trying'' to get themselves hurt to suffer for their past, so their new side offers them increased healing as a sort of compensation.

* The primary effect of the "Cure virus" in ''{{VisualNovel/Ever17}}'' is to give the infected party a healing factor that makes it impossible for them to be killed.
* Shirou has this in ''VisualNovel/FateStayNight'', spurring his famous "people (should) die when they're killed" line when he chooses to abandon it.
** All of the Servants have levels of superhuman regeneration as well. The speed of regeneration depends upon the Hero summoned as well as the amount of mana available (Archer takes several days to regenerate from being nearly cut in half),even lost limbs will eventually regenerate. To fatally wound a Servant, you have to damage their spiritual core (brain and heart) or destroy their bodies entirely.
* Subverted in ''[[VisualNovel/ChaosHead Chaos;Head]]''. Gigalomaniacs can alter reality, but they can't use their powers to heal. This is explained as an inability to block off person's sense of pain, which in turn disallows their delusions from taking effect.[[spoiler: This is eventually played straight with Takumi when he accepted his existence as an imaginary being, which allowed a complete control over his own form.]]
* The dragon and both the dragonslayer and his armor heal very quickly in ''VisualNovel/DraKoi'', especially during the climactic fight at the end. The hero can see the armor stitching or unmelting itself before his very eyes.
* Arcueid Brunestud from ''VisualNovel/{{Tsukihime}}'' has this, and a single night is more than sufficient to recover from ''being cut into seventeen pieces''. It cost her a lot of energy, though, and she stays weakened until nearly the end.
** Arcueid regenerated because, like all [[OurVampiresAreDifferent True Ancestors and the other vampires]], she possesses the Curse of Restoration, that turns her body back in time to before she was harmed. The stronger the vampire is, the greater is the damage they can regenerate from.
** Not exactly. While the curse of resurrection exists and she does possess it, she survived because she made a new body from scratch. The old one was "dead", Mystic Eyes of Death Perception not only bypasses all protections but is absolute. This is why Arcueid is so weak at the beginning of the Near Side routes. It took aLOT of energy this way.

[[folder:Web Comics]]
* Schlock, from ''Webcomic/SchlockMercenary'', as an amorphous life form, can regenerate from any amount of mass remaining, but as his memories are distributed throughout his body, he loses his mind if he takes enough damage. His eyes are actually separate lifeforms, that grow on trees on his homeworld. Uusually for this trope he needs to regenerate from what's left of his ''own'' mass. If enough of that is lost, he explicitly needs a large outside source of organic material.\\
Additionally, medical technology of the 23rd century can regrow your body from the head down in less time than it takes you to naturally heal a paper cut.
** Laz'r'us grade nanites appear to be able to provide this, as witnessed on the two occasions they're called on (for Kevin and General Xinchub).
* Vinnie, the werewolf soldier from ''Webcomic/{{Skins}}''. When he's fighting [[http://lj-phillips.deviantart.com/art/Skins-2-Preview-Doing-Hard-Time-378611792 another monster]] in [[spoiler: prison]] during a flashback scene, he has a broken nose, black eye and his arm so badly broken that the bone is protruding from the skin. But after he [[spoiler:shifts to werewolf form and back again]] he appears all healed up and actually looks quite handsome.
* ''Webcomic/SluggyFreelance''
** Aylee the alien has a powerful healing factor in some of her forms, at least the "larval" one she starts out in. Even years in, she still hasn't got the memo that Earthling limbs do ''not'' grow back.
** Though there are different types, at least some vampires have a Healing Factor that makes them unkillable other than by the proper means, eg. stake through the heart and garlic in the mouth. If you physically damage such a vampire's body ''really'' badly (eating their brains or cutting them in half isn't enough), they'll need special means to recover, but it's still possible.
** The mysterious brainwashed assassin Oasis, who keeps coming back from the dead, has an incredible normal-human healing factor according to [[http://www.sluggy.com/comics/archives/daily/010401 this strip]]. The suspiciously similar ([[RedOniBlueOni but opposite]]) Kusari also recovers from a broken leg within hours.
** While possessing Gwynn's body, the demon K'Z'K basically ignores ''any'' injury and pulls himself back together again. At one point Bun-bun [[http://www.sluggy.com/comics/archives/daily/990215 ran him through a meat grinder]] and [[http://www.sluggy.com/comics/archives/daily/990217 turned him into burgers]]. He was up and rampaging again [[http://www.sluggy.com/comics/archives/daily/990218 by the next strip]].
** Medical nanites (nano-robots) inserted into the body are invented in the course of the story that can grant a healing factor.
*** Dr. Crabtree, who was involved with their initial creation, eventually has so many in her body that she becomes a kind of nano-cyborg and can somewhat unreliably recover from just about anything... except for [[spoiler: an EMP]].
*** Medical nanites are a common feature in the alternative future dystopia 4U City. Though they wear out and you always need a new batch, they enable people to recover quickly from injuries, but every citizen also has a 'snapshot' taken of themselves clear down the the firing of every neuron in the brain that can be used to regenerate them with nanites. Too much damage causes them to revert to the state they were in when their snapshot was taken.
** Lodoze, a parody of SelfDemonstrating/{{Lobo}} in "GOFOTRON Champion of the Cosmos", heals any wounds and isn't even slowed down by anything less than YourHeadAsplode. Still, [[spoiler: he's presumed dead after his whole universe started a cycle of exploding and imploding]].
** Demons of the Dimension of Pain must have a Healing Factor considering [[http://www.sluggy.com/comics/archives/daily/20001018 what kind of injuries]] they sometimes inflict on each other for fun and subsequently ignore.
* One of the SuperSoldier implants in ''Webcomic/{{SSDD}}'' has this effect [[http://www.poisonedminds.com/d/20060623.html]]
* The protagonist in ''Webcomic/ArtificialTimeXS'', LetsPlay/{{raocow}}'s webcomic is so incredibly [[TheDitz stupid]] that she has the ability to forget and thus, heal every and all wounds. At first, she does feel pain and even passes out, but later on, as she becomes more insane, she doesn't even realize that she's getting injured and not only survives through, say, having her neck snapped, her head blasted off or her entire body being cut to pieces, but doesn't even react to it, [[{{Cloudcuckoolander}} happily and non-stop talking]] while she instantly regenerates from even the most grievous injuries.
* Damien from ''Webcomic/ElGoonishShive'' is expressly [[http://www.egscomics.com/?date=2004-04-26 stated]] to have this. Grace and her "brothers" as a shapeshifters presumably has this as well and by extension all Seyunolu and Uryuom have this to a certain extent.
* ''Webcomic/WaywardSons'': All Ulympeans and Tytans got this along with their PersonalityPowers. Beheading is the only way to kill them now.
* One antagonist, Gwenovere, from ''Webcomic/PowerOfEther'' can regenerate form injuries, which is convenient as she is a masochist.
* In ''Webcomic/ElijahAndAzuu'', it's common for both angels and demons to recover from grievous injuries, but one storyline firmly established that Azuu could easily regrow his arm after having it hacked off by a sword that specifically halts a demon's healing factor. His mom was injured by the same sword in an earlier story arc, and she had to consume several souls in order to recover.
* In ''Webcomic/{{Jack|DavidHopkins}}'' those who [[spoiler: "missed their chance to die"]] are apparently this, unfortunately they usually don't realize this. And it's [[WhoWantsToLiveForever implied to not be a good thing]].
* Webcomic artist [[http://shivae.net/ Tiffany Ross]] loves this one so much, two unrelated series have variations of it:
** ''Webcomic/TheCyantianChronicles'' has it as one of the traits of [[SuperpowerfulGenetics genetic elites]] including Alpha and his son, Syrys, Shean Tibal and his bad-boy son, Rama, as well as several cubs (at this point only shown with Rama's son, [[http://cyantian.net/akaelae/2005/03/03/d-26/ Vin]]). Also it only works if the subject is moving, as elites were originally intended as [[BloodSport pit fighters]].
** ''Webcomic/AlienDice'' gives us Lexx, who has been injected with repair nanites by the ADC so he can play their game and make the corporation wealthy.
* [[spoiler:Justin]] of ''Webcomic/WapsiSquare'' was revealed to have this power. [[spoiler:Several of his ex-girlfriends [[GoodThingYouCanHeal took advantage of this]] [[DomesticAbuse for their own amusement.]]]]
* In ''Webcomic/MoonCrest24'', Moon Crests provide this ability.
* In ''Webcomic/BobAndGeorge'', [[http://www.bobandgeorge.com/archives/000701c the Yellow Demon.]]
* The [[{{Mon}} battle monsters]] in ''Webcomic/ButImACatPerson'' can heal completely from almost any injury, although not so well that food and proper care don't help. Having done this for a couple thousand years now, they can be [[http://erinptah.com/catperson/comic/chapter-six-page-7/ pretty blasé]] about the gory details.
* In ''Webcomic/{{Nimona}}'', Nimona gets an [[AnnoyingArrows arrow wound]] in her leg that heals quite fast indeed. [[HandWave It's a shapeshifter thing.]]
** [[spoiler:Turns out she could have healed herself much faster, but held off to mislead Ballister as to the extent of her powers. When she wants to, she can grow an entire dragon body from a few blood cells. In fact, it's ultimately explained that whenever she shape-shifts (which she does casually) her entire body dies and is rebuilt instantly from scratch.]]
* In ''Webcomic/TheOrderOfTheStick'', Tarquin possesses a Ring of Regeneration.
* In ''Webcomic/WhenSheWasBad'', Max has a healing factor that is tied to his role as [[TheChosenOne chosen one]] Amber's bodyguard. It is very powerful in the beginning, when she is inexperienced and vulnerable, but decreases over time as Amber becomes stronger and less reliant on him.
* ''{{Webcomic/Zukahnaut}}'''s Hrothgar the Faceless is an Einherjar (a dead viking chosen by Odin to spend his afterlife in a warrior's paradise). He recovers from any injury as though he was still fighting in Valhalla.
* ''Webcomic/TowerOfGod'': Whenever Viole gets seriously injured [[spoiler: a red lobster-like being pops out of his back and]] he gets healed almost instantly.
* ''Webcomic/TheFarSideOfUtopia'': There are several characters - an unnamed individual that keeps popping up refers to himself as immortal and has visible fairly instantly regenerated damage (though not his clothes) from an explosion. [[spoiler:Mium]] also appears to regenerate from damage, if not instantly - including from being shot in the head.
* In ''Webcomic/StrongFemaleProtagonist'', an insanely powerful Healing Factor is [[DifferentlyPoweredIndividual biodynamic]] superhero Feral's main anomaly. Getting riddled by automatic gunfire will only result in her vomiting out the bullets a few seconds later, and even a sword embedded in her brain does little more than slur her speech and mess up her coordination for a bit. Spurred on by protagonist Alison quitting classic superheroism, she ultimately finds a way to use her powers to save more lives than mere [[TheyFightCrime crimefighting]] ever could: [[spoiler: becoming an effectively inexhaustible source for universal donor organs. She is voluntarily StrappedToAnOperatingTable - being ImmuneToDrugs, [[AndIMustScream fully conscious the entire time]] - and her organs, skin and blood are harvested as fast as she can regenerate them]].
* Seisha Dree in ''Webcomic/Harbourmaster'' was given genetic treatment to make her immune to Yogzarthu bioweapons. The modifications were more powerful than expected, though--she now regenerates from ''anything'', so long as she has enough backup protein to work with, and as a result [[OlderThanTheyLook barely ages, if at all]].

[[folder:Web Original]]
* ''Roleplay/GlobalGuardiansPBEMUniverse'' - This was a ''very'' common power. The all-time champion was probably Splatterman, so-called because he seemed to end up as {{chunky salsa|Rule}} every time he ended up in combat. Being aware of how quickly he healed, Splatterman would often put himself in position to have this happen, because he knew it wouldn't really slow him down. Leap off the top of a building? Sure. Jump through a wood-chipper? Yep. Swallow the live hand-grenade? You bet. And like a Timex, he took a licking and kept on ticking.\\
The villainous Nematode not only regrew parts that were cut off of him, but the parts would regrow into whole beings as well. Cut off an arm, and suddenly fight ''two'' Nematodes.
* This is so common in the Literature/WhateleyUniverse that there is a Regen ''scale'' describing how fast any mutant recovers from injury. Carmilla once was decapitated: her head grew back while the assailant stared in shock. Tennyo had her entire arm blasted off by a supervillain: she spun around and had completely regrown her arm by the time she got to him, intent on massive retaliation. Other characters have this to a lesser degree, including Generator and Peril.
* WebVideo/RickPointBlank: The plot revolves around a serum that heals wounds when it's poured on them and grants a Healing Factor that would make Wolverine jealous when injected. [[spoiler: Unfortunately it also causes insanity.]]
* In ''Literature/TheSalvationWar'', the demons and angels have extremely fast regeneration, to the point that they can regenerate lost limbs completely and can recover from any other injury given enough time, provided they don't immediately bleed out. This is deconstructed later on in the story's discussion thread, after [[spoiler: an angelic army gets nuked]]: the rapid regeneration rate, coupled with [[spoiler: rapid mutations due to immense radiation from the nuclear initiation]] results in uncontrolled cancer growth in the survivors. The deceased humans are also capable of healing rapidly.
* Veldron of ''Literature/SuperStories'' can [[GoodThingYouCanHeal regenerate when very close to death]], causing many to assume that he has this power all the time. He doesn't.
* In ''Literature/DeadWest'', the aristocrats might have this as a {{Psychic Power|s}}, commonly paired with HealingHands. The Porcelain Doctor has this, too, and he is [[PowerIncontinence "leaking"]], which means Gervas and Thomas also seem to display this. Niall states he cannot regrow limbs, but bones are apparently fair play. A French aristocrat said they can heal everything the body supposed to heal, but brain damage is a though deal. Most likely because their abilities are damaging their brains.
* ''Literature/TrintonChronicles'' has Xiion who heals at a highly rapid rate which he can do at will for a faster rate of healing or subconsciously for a slower but faster-then-normal rate.
* In ''Roleplay/WeAreOurAvatars'', Yasmin can heal incredibly quickly, to the point that she's [[MajorInjuryUnderreaction incredibly apathetic toward pain]]. There's also Ozzy (A.K.A. Gina), Snake, and various other Gods/Characters who have this ability.
* Discussed in a couple ''Website/{{Cracked}}'' articles:
** [[http://www.cracked.com/blog/7-bullshit-video-game-healing-methods/ 7 Video Game Healing Methods Least Likely to Actually Work]]
** Portrayed as undesirable in ''Website/{{Cracked}}'''s [[http://www.cracked.com/article_20241_6-awesome-superpowers-that-would-suck-in-real-life_p2.html 6 Awesome Superpowers (That Would Suck in Real Life)]] because the intense pain would lead to post-traumatic stress disorder.
* Othala from ''Literature/{{Worm}}'' has the power to grant this to other people.
** Then, of course, there's Crawler who can regenerate any injury in seconds - even having half his brain teleported into a parallel dimension - and then [[AdaptiveAbility develops a permanent resistance]] to whatever hurt him in the first place.
* ''WebAnimation/{{Xin}}'''s titular protagonist knows a technique wherein he uses Qi to quickly mend broken bones. Subverted in that this technique is only a temporary solution, and he needs to have his bones properly mended after fights.
* ''WebVideo/DeathBattle'' factors this trope in determining a victor, but in this case it's determining how powerful it is to prevent them from dying. [[spoiler:This is a major factor in the wins for Deathstroke vs. Deadpool, Wolverine vs. Raiden, and Hulk vs. Doomsday. The first and the last are especially notable because Deadpool and Doomsday's healing factors are insanely more powerful than Deathstroke and Hulk's (Deadpool is able to reattach his arm and leg twice after he got them mixed up while Doomsday repaired his completely and utterly ruptured arm after Worldbreaker Hulk crushed it. Both would go on to gut their opponents and take their heads off.)]]

[[folder:Western Animation]]
* The Minions of Set from ''WesternAnimation/SamuraiJack'' have an incredibly powerful healing factor. Even Jack's sword, forged by the gods themselves out of the power of human righteousness, and the only thing in the universe capable of harming the [[MadeofEvil Made of Evil]] Aku, only slows them down for mere moments. They can regenerate from nearly being cut in half with it in less than a second, with no side effects whatsoever.
* In ''WesternAnimation/JackieChanAdventures'', the Horse Talisman does this, granting whoever has the power to heal almost instantly from injuries, together with the [[ImmortalityInducer Dog Talisman]], which grants immortality and eternal youth/youthful energy (the energy going to those above a certain age) they grant CompleteImmortality.
* Starscream gets this in ''WesternAnimation/TransformersAnimated'' from an Allspark fragment in his head.
** Which is based on how G1 Starscream was {{Ret Con}}ned into having one to explain how he came BackFromTheDead.
*** But that was only his spark (soul) which was immortal, he didn't have a body, regenerating or otherwise. Which lead to him floating around like a ghost for quite some time until he could scam himself a new shell (or steal someone else's).
** Transmetal 2s in ''Franchise/{{Transformers}}: WesternAnimation/BeastWars'' have the ability to heal mild to moderate damage near-instantaneously using energy from their spark. Rampage also has one, as he was created by an experiment to duplicate Starscream's spark.
** Godmasters in ''Anime/TransformersSuperGodMasterforce'' have this as one of their defining features.
** Megatron in ''Anime/TransformersCybertron'' can regenerate damaged parts of his body much more easily than ordinary self-repair systems thanks to the Armor of Unicron. Stealing a Dark God's power has its perks.
* ''WesternAnimation/{{Gargoyles}}'' have a form of accelerated healing attached to their stone sleep. Spending a day in stone sleep cures them of any wounds, infections or toxins in or on the body. However, if a body part is amputated, it's gone for good. This only applies to their hibernation. Until the sun rises, they're as badly affected by an injury as any other creature. Demona and [=MacBeth=] appear to have this, too, [[spoiler: as long as they're not in the same room]].
* WesternAnimation/{{SpongeBob SquarePants}}, [[JustifiedTrope being a sponge and all]], can grow back severed parts of his body with no problem. He was surprised when he found out others couldn't do it as well.
** In "Karate Star", Patrick tears off his karate chop arm in order to stop the wreckage he's uncontrollably causing. He grows his arm back, but the arm grows a new body, as is typical for starfish.
* ''WesternAnimation/DarkwingDuck'': Bushroot's Healing Factor is seldom seen, but he completely recovers from being squashed in his first episode and later from being shredded into small pieces. Being part plant helps.
* Killface of ''WesternAnimation/FriskyDingo'' has a rather handy healing factor. Metal pipe through the lung? Nah, tend to Simon's scraped arm. Rocket through the chest, and a gaping hole from the explosion? Fixed with a little bedrest. Though his healing factor was unable to heal his eyes after he was blinded by [=AntAgony.=]
* ''WesternAnimation/AdventureTime'': The Ice Crown grants this to its wearer, to the point where both wearers shown were able to ''survive nuclear war''. Marceline also seems to have this due to her demonic ancestry, although it isn't as powerful as the Crown's.

[[folder:Real Life]]
* The axolotl is a neotenous amphibian that can regenerate limbs and organs that were damaged or lost. Although it doesn't give it {{Immortality}}, it does make it live much longer. It's used as a model in biomedicine.
* Salamanders are perhaps the most complex animals capable of regenerating limbs in adulthood.
* There are some species of starfish that not only grow new limbs, but the detached limb can grow a new starfish!
* Sponges can be put through a fine strainer and they will eventually recoalesce.
* Flatworms can regenerate bits, including [[http://www.theverge.com/2013/7/10/4510580/planarian-worm-regrows-memories-after-decapitation heads]], although it's possible to mess with this in ways that result in two-headed flatworms.
** Some round and segmented worms also can do that, but with the two-tailed and two-headed mistakes as well. It generally depends on the location and extent of the injury.
* Most leafy plants are able to regenerate from practically any damage, as long as they can still acquire nutrients and the materials needed to synthesise sugars (in other words, their roots and/or leaves still need to be at least partially functional). Many plants can be propagated simply from cuttings. In fact for a large number of domestic fruit trees, grafting a piece of an existing tree onto an existing rootstock is the only way that they are reproduced. Moreover, using special nutrition, leaf plants may be regrown FromASingleCell.
** As a specific example, notable even among leafy plants, willows are extraordinarily regenerative plants which actually grow more lushly if some of their limbs are hacked off; they can even regrow from piles of wood-chips. Most plants are less enthusiastic about damage. But putting a cutting from a willow in the same basin of water as a cutting from another plant can encourage the other cutting to start sprouting roots - the hormones the willow puts into the water affect the other plant too.
* There is anecdotal evidence that toddlers can regenerate fingertips that have been severed for whatever reason (not the entire finger, just the top 1/8 inch or so).
** Supposedly, a man was able to regrow a fingertip that was cut off by applying a special powder, given to him by a researcher, to the open wound. There was a report on Creator/TheBBC a while back.
*** That sounds like dehydrated Extra Cellular matrix, it's a sort of universal animal cell growth medium, by applying dehydrated stuff to the wound it re-hydrates and triggers the growth of the surrounding tissue.
* The liver in humans is said to regrow from just a third of its normally functioning tissue. This is why living-donor liver transplants are possible (although hardly easy): the donor can lose 55-70% of his or her liver and expect to have it back to near 100% functioning within six weeks, and it will be fully up to normal size and structure within two to three months.
* Blood platelets. When flesh is cut, leading to bleeding, blood platelets are life-savers. They cause blood clots (better known as scabs) along the cut, stopping the release of blood until other body functions can fix up the blood flow. This makes them sort of a pre-Healing Factor Healing Factor.
* Humans do possess the Genes to regenerate limbs, however they are heavily mutated and are considered Junk DNA: Anti Heat Shock Protein 60 and Fibroblast Growth Factor 20 are in both humans and certain types of Zebrafish and Salamanders. Those with the mutant variants of the gene only get scarring. For the animals with the functioning genes, the cells around the wound site revert to their embryonic state and reform the lost part.
* Even without the ability to regrow lost limbs, humans still have an amazing healing ability when [[HumansAreSpecial compared to other species]]. Our ability to recover from injury and our resistance to shock is absurdly high compared with other animals, and coupled with our high endurance this allows us to recover from virtually any injury that is not immediately fatal. Humans also form scar tissue at a much higher rate than any other animal on Earth, meaning a wound that might take an animal months to heal could be healed on a human in weeks.
** [[http://whyquit.com/whyquit/A_Benefits_Time_Table.html A timeline of what happens with a smoker quits]] is one very good piece of evidence to show just how good the human healing factor is. To put it in perspective, it takes under a year for the body to return to more or less normal function. The risk of nasty diseases will drop significantly within years.
** It's speculated that the reason humans are unable to regenerate limbs is because having this ability would drastically increase our chances of getting cancer.
* Spiders can regrow lost limbs when they molt. However, their ability to heal injuries to the torso is poor, especially in tarantulas. Many other arthropods can replace appendages during a molt as well.
