History HealingFactor / AnimeAndManga

* Dante from ''Manga/BlackClover''. His innate magic is Body Magic, regenerating his flesh to heal himself. Thanks to hosting the high-ranking devil Lucifero, this power is incredibly boosted to the point he can't age, deteriorate, or die. He survives getting slashed through the chest and having his torso destroyed repeatedly, regenerating his body to become a distorted, muscled giant.

** On that note, Highway Go Go/Highway Star Green Day/Green Tea, Catch the Rainbow and Tusk (ACTs 1-4) allow the user to heal themselves/regrow body parts. And that's not even to mention Stand users who can freely apply their Stands' negative effects to themselves to conceal them being the real user, but reverse them at any moment. (i.e Grateful Dead's aging power can be applied to the user too).

* ''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.

** 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. Tobi also uses Hashirama's cells to negate the PowerDegeneration of using his Mangekyo Sharingan, which considering how much he spams it would have gone blind long ago otherwise.

** 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.

* 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.

* ''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.

* Recovery Girl in ''Franchise/MyHeroAcademia'' is a variant. She’s able to induce other people’s healing to speed up. Very handy in a school of wannabe superheroes who can’t control their powers yet. But she ultimately pts limits on Midoriya, telling him she won’t heal all of his recklessness-induced injuries so he’ll work on achieving better control.

* ''Manga/FairyTail'': Sherria Blendy's Sky [[KillTheGod God Slayer]] Magic notably gives her the ability to heal her own injuries alongside its other healing powers, which is something Wendy's own Sky [[TheDragonslayer Dragon Slayer]] Magic can't do. However, Sherria's healing can't restore lost stamina on its own unlike Wendy's, forcing her to rely on consuming air alone to recharge, and therefore she can be worn down through attrition.

* In ''Manga/{{Berserk}}'', the [[TheLegionsOfHell Apostles]] can usually heal from wounds if given time. [[BloodKnight Zodd]], for example, has had his arms sliced off multiple times, but he simply bends down, picks up the severed arm, and reattaches it like he's made of Lego. However, when Griffith forced him to join his cause, Zodd lost his horn and it hasn't grown back, so it seems Apostles can't heal metaphysical injures.

* 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]]. A vampire's healing factor is explicitly weakened by [[WeakSauceWeakness poison]], yet Araragi is usually up and running by the next morning.

* In ''LightNovel/ACertainMagicalIndex'':

* 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/{{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]].

* Yuki Nagato from ''LightNovel/HaruhiSuzumiya'' 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.

* The Pro Hero Zombieman from Manga/OnePunchMan has this ability, able to heal from any wound with ease. It's said that the only way to kill him permanently is by completely reducing him to mincemeat. Even if he's only a head he can regrow his body.

* 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]]]].

* ''LightNovel/ThatTimeIGotReincarnatedAsASlime''

* Abel from ''LightNovel/TrinityBlood'' has been shown regenerating a lost arm (from the leftover pool of blood) after it was blown off.
* [[GiantSquid Poseidon]] and [[WhenTreesAttack Yggdrasil]] in ''LightNovel/UndefeatedBahamutChronicle'' both have this. Both routinely gets their tentacles/branches destroyed and regenerate them almost as quickly. Yggdrasil can also implant its parasitic seeds into other things to give them a healing factor as well. [[spoiler:Philuffy]] is a surviving host of Yggdrasil, and demonstrates the ability to recover in several days from a wound that would be fatal to a normal human.

* In ''LightNovel/MagicalGirlRaisingProject'', Hardgore Alice can regenerate from any injury as long as a molecule of her still exists. She has her stomach blown open, [[LosingYourHead she's decapitated]], she's burnt to ashes, and she heals up quickly no worse for wear. [[spoiler:However it only works in her magical girl form. She is eventually ambushed and stabbed in her human form. She tries to save herself by transforming, but cannot concentrate enough to do it and succumbs to her injuries.]]

* 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.
* From ''Anime/DragonBallSuper'', out of the two {{Arc Villain}}s of [[EvilKnockoff Goku Black]] and [[GodIsEvil Zamasu]], Zamasu's fighting gimmick is that a wish for CompleteImmortality made him [[NighInvulnerability nearly indestructible]] and had this trope fill in for where he wasn't. Later [[FusionDance the two fused]] into a new entity called Merged Zamasu, with the intent of having Zamasu's immortality and Black's seemingly endless potential. The consequences of this are different between the anime and manga:
** In the anime, things go awry due to Merged Zamasu [[OxymoronicBeing being simultaneously mortal and immortal]] (combined with Black's biology attempting to [[CameBackStrong improve damaged body parts]] while Zamasu's immortality attempts to revert them to their original state). Not only is Merged Zamasu killable, but healing from damage causes him to [[BodyHorror become increasingly mutated and deformed]]. Unfortunately, killing him [[OutOfTheFryingPan turns out to actually make things worse]], as Zamasu's immortality continuously attempting to "heal" his disembodied spirit causes it to become an infinitely-expanding EldritchAbomination.
** In the manga, Merged Zamasu's fusion [[HourOfPower has a 1-hour time limit]], but while fused he repeatedly has parts of his body destroyed and regenerated. Combined with the villains' exceptionally high compatibility [[spoiler:due to Goku Black being a Zamasu from another timeline]], this results in his HealingFactor interpreting the end of the fusion as damage, causing Goku Black and Zamasu to ''heal into two Merged Zamasus''. Worse, it soon turns out that this development isn't a one-off, and splitting either of the Merged Zamasus' bodies apart will now result in each piece regenerating into a new Merged Zamasu.

* 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 because it can lead to various kinds of brain damage (when Reiner recovered he was severely disoriented and had lost several hours of memory)]].

** 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]].

** {{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 Inu-Yasha]]. 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]]'']].

* 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.

** Finally there's [[UpToEleven Endless Regeneration]], which is not only even faster and stronger than Ultraspeed Regeneration, but it also heals soul damage. In other words, the only hope of killing someone with ''this'' skill is to [[NoKillLikeOverkill completely destroy]] their [[DeaderThanDead body and soul]].

* In ''Manga/{{Berserk}}'', the [[TheLegionsOfHell Apostles]] can usually heal from wounds if given time. [[BloodKnight Zodd]] for example has had his arms sliced off multiple times, but he simply bends down picks up his arm and retatchs it like he's made of lego.
** However when Griffith forced him to join his cause, Zodd lost his horn and it hasn't grown back, it seems Apostles can't heal metaphysical injures.
