Healing Factor / Anime & Manga

Healing Factors in anime and manga.

---

• Chirico Cuvie from Armored Trooper VOTOMS 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 Villain Protagonist of Assassination Classroom, 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 Attack on Titan, 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. 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 Slashed Throat that should have been fatal and is barely slowed down. Reiner took this up to eleven 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).
• Immortals in Baccano! get this standard with their immortality. They also avert the 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) 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.
• Mostly human protagonist Araragi Koyomi from Bakemonogatari can survive surprising amounts of punishment, up to and including getting his heart torn out of his chest. A vampire's healing factor is explicitly weakened by poison, yet Araragi is usually up and running by the next morning.
• In Berserk, the Apostles can usually heal from wounds if given time. 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, reincarnated after becoming the God Hand Femto, 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.
• The 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.
• Dante from Black Clover. 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. Even when his defeat against Magna sees him completely run out of magic power, his Body Magic still tries to heal the damage further fueled by his rage at being bested by a commoner, though there the results are rather... uncontrolled.

• Killy from 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 the weapon he uses.
• 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, though they retain a version of it when they activate their Resurreccion to heal any injuries they received in their base forms (though if they take damage in this state, all bets are off).
  • While Ichigo is fighting his Inner Hollow in his Mental World, the Visored take turns to contain his Hollowfied body in the real world. At one point Kensei blows his arm clean off, only for Ichigo to grow a new one in seconds.
  • Aizen has this once the Hogyoku starts "evolving" him and granting him more power. Case in point: he survived Ichigo's ultimate attack that bisected him vertically, blew off most of the fancy features of his One-Winged Angel, and eclipsed a mountain range. Even after he lost most of said powers, he kept the healing which allowed him to come back from being struck by Yhwach, who after having absorbed the Soul King was pretty much the World's Strongest Man and a Physical God.
  • Similarly, the Vandenreich give us Giselle Gewelle and apparently Askin Nakk Le Vaar. In the case of the first, she's able to easily survive being nearly cut in half. Later, when Ichigo arrives and tosses her and other characters into a bunch of destroyed buildings, the impact breaks Giselle's neck... but not only she survives to that, but she then puts her own neck back in place like it's nothing. ( 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 has the power of surviving every time he should be close to death — which might have allowed him to, alongside Ishida, survive The Purge from Yhwach.
• Rin from Blue Exorcist heals from wounds pretty fast. Like, getting stabbed in the stomach only for it to heal in mere minutes? Arthur even cut off his foot, since he knew it would grow back sooner or later.
• In Blue Ramun, the people of the Blue Ramun tribe heal at an accelerated rate because their blood naturally has healing properties. Most cuts and bruises they sustain heal inside of a few hours, and the blood they give on a daily basis (to use in medicines and poultices) seems to regenerate without issue. When Jessie is stabbed in the stomach at the end of Volume 1, she recovers completely from the wound in just few days.
• The monomakia from Brigadoon: Marin and Melan 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.
• Buso Renkin:
  • Gekisen, the cross-spear buso renkin of Alchemist Warrior Genji Ikusabe, gives him the ability to regenerate any wound inflicted on him, up to and including the complete destruction of his body, as long as he was holding the spear when the wound was inflicted.
  • All homunculi have a natural healing factor that allows them to almost instantly regenerate any damage caused by non-alchemical means. A homunculus can also regenerate damage cause alchemy but it takes longer and if their emblem mark weak point is destroyed then they will die.
• A Certain Magical Index:
  • 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. It's not clear if the same applies to the rest of his body — he often has to spend time in the hospital after severe injuries — but it's speculated by fans that this is the case.
  • 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 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 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 creation. In short, a form of the healing factor residing in the domain of gods.
• C.C. from Code Geass, 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: 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 Humongous Mecha, meaning she had to purge the cockpit and die at least twice due to pressure and drowning before she floated to the surface; Word of God 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. Which was actually already there when she got her powers
  • In the audio commentary, when the staff and cast discuss C.C.'s powers, voice actress 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
• Corpse Princess 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.
• Crazy Food Truck: Arisa (and her little "sister" Myna) can heal within a day from wounds that would take much longer for normal people. When she stops healing quickly, Gordon realizes something is wrong.
• Princess Ixquic from Cyborg 009. Then it's subverted, since she's a Robot Girl.
• In Date A Live, 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 Demon King Daimao, Sai gets an arm chopped off. The stump sprouts a new one, out of blood, which regenerates back to a regular arm in seconds.
• D.Gray-Man:
  • 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 up to eleven in the Alma arc, in which both Kanda and Alma come back from being blown up. Alma was the bomb. Subverted in that Alma dies soon after and Kanda's healing factor seems to have run out.
• The Gadoll from Deca-Dence are extremely dangerous for their ability to regenerate limbs and heal wounds within seconds so long as they have enough of their blood, "oxyone", in their systems. The primary means of dispatching them is by hitting their major arteries with special harpoons to bleed them to death and if they're too large for that, a single burst of massive, blunt-force trauma with a jet-engine powered fist also does the job.
• Kyouya from 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 Dragon Ball, 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 From a Single Cell thanks to having both Piccolo's regeneration and Freeza's 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 Dragon Ball Super, out of the two Arc Villains of Goku Black and Zamasu, Zamasu's fighting gimmick is that a wish for Complete Immortality made him nearly indestructible and had this trope fill in for where he wasn't. Later 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 being simultaneously mortal and immortal (combined with Black's biology attempting to 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 become increasingly mutated and deformed. Unfortunately, killing him 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 Eldritch Abomination.
    • In the manga, Merged Zamasu's fusion 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 due to Goku Black being a Zamasu from another timeline, this results in his Healing Factor 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 Durarara!!, Quarter-Dullahan Ruri Hirijibe has this ability. A comment made by Shinra while treating her wounds suggests that not only does (the entirely human. Supposedly) Shizuo Heiwajima have this as well, but that his is greater. If nothing else, it would explain how he's recovered completely from things like shattering his spine and pelvis or getting shot.
• Both Yukiko and Liselotte Werckmeister from 11eyes 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.
• Fabricant 100: Carriers of Yao blood heal any injuries quickly, which include Ashibi and any Fabricant that has escaped with a flesh of his family.
• Fairy Tail: Sherria Blendy's Sky 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 Dragon Slayer Magic can't do. However, Sherria's healing can't restore lost stamina on its own like Wendy's, forcing her to rely on consuming air alone to recharge, and therefore she can be worn down through attrition.
• Self-healing is most common type of Blessing in Fire Punch, ranging from healing heavy wounds in weeks, to growing missing limbs in a few moments, to brushing off headshots. Regeneration-type neither age past adulthood nor required sustenance. All of their powers quite explicitly have No Conservation of Energy, which Agni has used to continuously cut off and regrow limbs he'll give to other as an emergency food supply.
• Franken Fran:
  • Chapter 3 is the story of a girl with a Healing Factor that reached Body Horror 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 Born Lucky.
• The Homunculi from Fullmetal Alchemist all have this power. The Shapeshifter Baggage 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 Deader than Dead).
• GUN×SWORD: 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 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.
• Guyver: The Guyvers from 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 Haré+Guu, Guu regenerated her arm. After chopping it up and eating it.
• Yuki Nagato from Haruhi Suzumiya is able to regenerate using her Magic from Technology, apart from being seemingly unaffected by physical injuries. The limits are unknown, but it does happen in an instant.
• Most of the major characters of 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 'he was never there in the first place' variety.
• The nations of Hetalia: Axis Powers have this, and it allows them to regenerate near-instantly from wounds that would be fatal to humans so long as the country they personify remains intact. In fact, one of the signs that Prussia may be beginning to fade away or die after no longer being a country is when his brother Germany notices that Prussia has been bitten by one of Germany's dogs, Germany thinks dismissively that the bite will heal right away. As it turns out, he was bitten a week earlier.
• Inuyasha:
  • Youkai always heal much quicker than humans do and Sesshoumaru is tougher than most. At one point, he gets his one single arm torn to shreds resulting in him having to be rescued by Inu-Yasha. This results in the following exchange, which angers Sesshoumaru so much that he actually earns a regeneration upgrade that, by the end of the fight, enables him to not just regenerate the damage to his right arm, but to also eventually regenerate his missing left arm.
    Inu-Yasha: [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 Meidou Zangetsuha was turned over to someone like you that Sesshoumaru-sama has...
    Inu-Yasha: Shut up! [thinks] I know that. 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 hanyou...
    Jaken: Oooh! He closed his wounds with 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.
• Is This A Zombie?: 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 JoJo's Bizarre Adventure, vampires and the Pillar Men have this, making them immortal. The only way to kill them is with sunlight or the Ripple.
  • Although, as demonstrated in Joseph's fight with Straizo in Battle Tendency and Jotaro's fight with Dio in Stardust Crusaders, the healing capability of vampires has a weakness in that it can take several moments for significant injuries to heal, and seem to be flat out incapable of regenerating lost body parts. The Pillar Men's healing ability, though, is on a whole different level — they demonstrated the ability to not only completely ignore such injuries, but even hijack replacement limbs from corpses with little effort.
  • Okuyasu's father in Part 4 also has this. In his case, it's an example of Blessed with Suck 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.(Speculated to be his un-named Stand)
  • 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).
• Jujutsu Kaisen: Reverse Cursed Technique is an application of cursed energy manipulation that takes cursed energy, multiplies it by itself and turns it into positive energy, becoming energy capable of creating rather than destroying (as a consequence, RCT requires double the output of cursed energy). This ability by itself usually translates to healing injuries, but only for sorcerers; because cursed spirits are already made of cursed energy, they do not need RCT to do so (not that all of them can heal themselves, either). Regardless, although RCT sounds simple on paper, it is in fact incredibly complex for most sorcerers, and even if they can pull it off they are only capable of either healing others or healing themselves. The most skilled users of RCT can even restore their burnt-out cursed technique after expanding their Domain by healing the section of their brain where the technique's information is stored, although doing this too many times in a row runs a severe risk of incurring brain damage.
• One of the abilities of Life Fiber hybrids in Kill la Kill, including protagonist Ryuko.
• In Love Hina, Keitaro's immortality is expressed as being able to completely heal from the worst 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 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 said he used up all his luck.
• Lyrical Nanoha:
  • The Wolkenritter of Magical Girl Lyrical Nanoha A's. They may have lost the 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 her getting impaled in the chest could take her out permanently.
  • In Magical Record Lyrical Nanoha Force, and we're introduced to the Huckubein, who can regenerate even better than the Wolkenritter. Cypha proves this by regrowing an arm that Signum cut off. Oh, and they're also pretty darn tough too.
  • Force also revealed that Hayate gained some of the Wolkenritter's healing factor when she absorbed the Tome of the Night Sky and became the "Walking Lost Logia". Not enough to survive a mortal blow, but enough to recover from wounds faster than usual.
• The Immortals from the Mermaid Saga can regenerate from any wound, naturally, except burning to ash or having their heads completely severed.
• Dragons in Miss Kobayashi's Dragon Maid are capable of recovering from fatal injuries overnight. There's also a Running Gag of Tohru chopping off her tail and trying to feed it to Kobayashi, only to grow it back in a second. That said, it does have its limits considering that Ilulu still hadn't fully recovered from her fight with Tohru several months after the fact.
• This is Rin Asougi's only power in 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 Blessed with Suck.
• Musuko ga Kawaikute Shikataganai Mazoku no Hahaoya: Lizette is able to instantaneously heal her wounds if she consumes enough blood. Following Lizette drinking some blood after being exposed to sunlight and burned then healing instantly, Chiharu is stunned and questions the biology behind it.
• Naruto:
  • Subverted in some aspects with Tsunade and Naruto: They can regenerate from grievous injuries very quickly, but they do so via rapid cellular growth, which ages their bodies prematurely and shortens their lifespans (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 Long-Lived 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 Grand Theft Me 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 Madara are able to pull this off thanks to cloned flesh grafts from Hashirama. Tobi has sacrificed his right arm on a few occasions while Madara recovered from losing an arm and having most of his chest cavity pulped. Tobi also uses Hashirama's cells to negate the Power Degeneration of using his Mangekyo Sharingan, which considering how much he spams it would have gone blind long ago otherwise.
  • 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, 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.
• Negima! Magister Negi Magi:
  • Kotaro has one as part of his ultimate demon form, 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. Naturally, he promptly runs into an opponent who can bypass that protection...
  • Evangeline can easily heal things like being impaled, losing a limb or having her hair cut in a matter of seconds.
• Berserk Evangelions from Neon Genesis Evangelion have this ability, ranging from regrowing shattered bone to manifesting whole limbs out of angelic flesh or its own AT Field. Angels have his by default, as all of them have S2 organs and couldn't operate alone without support units.
• Setsu, the protagonist of Oddman 11, usually frequents the local comic store for healing. While at first the audience is led to believe she means some sort of "emotional healing" through reading manga in there, she's actually shown recovering broken bones and torn-off skin unusually fast while inside the store. This is noted as strange by other characters, even considering the scope of the Oddmen's strange characteristics.
• Both averted and played straight in One Piece. Characters who have eaten 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 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.
• The Pro Hero Zombieman from One-Punch Man 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.
• This ability is one of the signs that the Baskervilles from PandoraHearts are Not Quite Human: they can recover very quickly and survive any attack from ordinary humans, including a bullet to the head. Only a select few Chains (and their contractors) can kill a Baskerville, most notably Mad Hatter and the Blood-Stained Black Rabbit.
• In Pokémon Adventures, Arbok is shown to be able to regenerate from any injury (other than decapitation) after Blue's Charmeleon cuts it in half across its hood.
• In Pokémon: Destiny Deoxys Deoxys is depicted regenerating a vaporized limb. In fact, it can regenerate its entire body as long its crystal core is intact.
• In Popcorn Avatar, this is one of Ryuudou Taiga's abilities as his sister's avatar.
• Puella Magi Madoka Magica: Sayaka gets this, as a result of her wish involving healing. While all magical girls have some degree of enhanced healing, Sayaka can do it much faster and more thorough. In the original anime alone, she is hit hard enough to break every bone in her body and later completely eviscerated, but gets up a few seconds later. In various spin-offs, it's shown that she can heal broken or even lost limbs in less than a second or survive lethal injuries like having her heart ripped out. It's implied that nothing short of destroying her Soul Gem could actually kill her for good.
• Taken up to eleven with Saffron in Ranma ½. 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 Good Thing You Can Heal.
• Rooster Fighter: The Nume demon quickly regenerates from Keiji's attacks by hiding its organs in its tail. He just increases his range until there's nowhere to hide.
• Loosely implied to be a vampire's source of immortality in Rosario + Vampire. Their blood has a powerful regenerative effect on anyone, which Tsukune is quick to demonstrate once this is introduced. 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. Even cutting her in half won't be enough to kill her.
• The Wu from the manga and anime 3×3 Eyes 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 Slayers, trolls have such fast regeneration abilities that they are nearly impossible to kill. The main character, Lina Inverse, solves this issue by casting a magic-reversal spell on all the trolls so that even the tiniest scratch results in nearly instant death-by-implosion.
• Soul Eater 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 re-attach a limb.
• Tengen Toppa Gurren Lagann — 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 hundreds, possibly thousands of years before episode 1 takes place.
• That Time I Got Reincarnated as a Slime
  • First there's the skill Self-Regeneration, which is a natural skill many monster races possess that can heal physical injuries as long as enough time is given for it to work. However, this time requirement is the main weakness, so an instantly fatal attack to an organism's vital organ like the heart or brain can overcome it or just attacking with a higher frequency than can be healed.
  • Then there's the upgrade Ultraspeed Regeneration, which ups the potency and speed of the healing to the point one can recover from otherwise fatal injuries nigh instantly. The only weaknesses at this tier of healing would be attacks capable of completely destroying the foes body, or attacks that strike directly at the soul as the skill only heals physical damage.
  • Finally there's 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 completely destroy their body and soul.
• In Tiger & Bunny, one of the less utilized advantages of Kotetsu's 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 Tokkô, a healing factor is one of the powers gained by people with phantoms living inside them.
• The titular Ghouls in Tokyo Ghoul can regenerate as part of their standard set of superhuman abilities. This ability varies wildly between individuals, with the 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 stabbed through the skull twice. The most extreme examples in the series are horrific beings capable of literally Pulling Themselves Together, 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.
• The title character of Tomie has this ability to the extent that every single individual piece of her that is cut off will eventually become a new Tomie. This is justified by Tomie being radiotrophic, feeding on background radiation in the air and somehow converting it into mass.
• Quon of Towa no Quon has this as one of his abilities.
• In Trigun, 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 Cast from Lifespan.
• Abel from Trinity Blood has been shown regenerating a lost arm (from the leftover pool of blood) after it was blown off.
• The titular Undead of Undead Unluck, AKA Andy, has one of the strongest and most versatile healing factors in fiction. His Negator ability negates his own death, including any injury that would bring him closer to death. This means he can regenerate from any injury in seconds, in addition to being Ageless. The sheer speed of this regeneration is also what gives Andy his main offensive moves, as he can use his regeneration to shoot his own body parts at people. In order to do so he first needs to slice partway through the body part, and then grow a brand new one to launch it. He can also fire High-Pressure Blood strong enough to slice through an entire skyline, create duplicates by generating entire new bodies from each body part, and perform Iaijutsu using his own body as the sheath. His healing factor is so powerful he even lives through the apocalypse and rebirth of the universe. Multiple times.
• Poseidon and Yggdrasil in Undefeated Bahamut Chronicle 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. 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.
• Inugami Akira of Wolf Guy - Wolfen Crest has this on account of being a werewolf. During the full moon, he's night invulnerable.
• In Wonder Egg Priority, Ai and the other Wonder Egg hatchers are shown to have this ability while they're in the Eggs' dream worlds, healing almost instantly from any wounds they may sustain. The twist is that this doesn't apply to the real world - once they awake in reality, they'll still have whatever wounds they sustained, and invariably end up being rushed to hospital.
• YuYu Hakusho. 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 even a single cell of him is still alive. So Kurama ultimately traps him in a Fate Worse than Death. The younger brother also has a healing factor, though not as strong as Elder Toguro's, as shown when 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 Made of Iron.
