Healing Factor / Fan Works

Arrowverse

• The Flash (2014)/Supergirl (2015) crossover Call Me Kara provides several examples:
  • Both Kara and Barry have this power naturally, though it takes a backseat to their more spectacular powers. Nyssa points out how valuable of an ability this is and convinces Barry to train this ability to heal from injuries in seconds as opposed to hours, which Kara also learns to replicate (albeit on a lesser scale)
  • Unfortunately, Doomsday also has this ability, and its immortality is one of reasons Barry trains to master the Infinite Mass Punch, as nothing else would be able to kill it.

Crossover

• BlazBlue Alternative: Remnant (BlazBlue & RWBY):
  • When Ragna enters his Unlimited Mode, his body completely heals from all previous wounds and patches whatever damage he soaks up while in this state. It gets noted that if not for the holes in his clothes, there's no sign that he was ever injured at all.
  • Terumi seems to have a much faster healing factor than most people on Remnant, effortlessly shrugging off Adam impaling him through the chest, with the wound healing just seconds after he removes the sword. During his fight with Ruby, she blasts half his face off with Crescent Rose, and it completely restores itself within a few minutes.
• The Bridge (MLP):
  • 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 when near each other.
  • As King Sombra runs on The Power of Hate, the angrier and hateful he gets, the faster he heals. He'll still die if he's blown to bits.
  • 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. Dark magic also disrupts the healing factor.
  • 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 feeding on someone. After Aria Blaze 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, then become immune to whatever damaged him. Even his mask repairs itself when damaged. However, it only works if he's touching the ground, so if he's knocked into the air, he can be killed.
• Child of the Storm 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.
• Dungeon Keeper Ami: Youma can heal lost limbs given enough time and magic to eat.
• Equestria Girls: Friendship Souls (Bleach & My Little Pony: Equestria Girls):
  • All Hollows and Arrancar have one to an extent, but The Lament's stands out. While he admits his healing isn't as fast as the other Espada, it doesn't really matter because his body doesn't truly bleed nor do his organs actually function. He can get his entire body perforated by attacks and walk it off without issue, and he notes that nothing short of completely destroying his body would probably kill him.
  • Chrysalis is noted to have an abnormally powerful Healing Factor as well, shrugging off attacks that leave her limbs and organs mangled with barely a thought and regenerating an entire lost side of her body ala Perfect Cell with as much nonchalantness. It's to the point Sombra has specifically picked out Sternritter capable of negating her Healing Factor to fight her, and she still doesn't have too much issue in the fight. About the only time she's ever shown real worry is when faced with an attack that could legitimately destroy her in one go if it properly connected.
  • The Smooze is no less impressive in this department either, capable of regenerating as long as a scrap, or at least the core of his Blob Monster body, remains intact, though Grogar is of the opinion he's not so much regenerating as replacing his lost mass. As such, nobody on the Espada's side really believe he dies from Lightning Dust's Death or Glory Attack and figure he went off to recover. As it turns out, he did survive, though circumstances meeting Fluttershy dictate he decides to take a new career path.
  • Sunset's shield, Hikari, can heal her wounds.
  • Hoity Toity, as an extension of The Xenomorph's ability to alter physical matter, can use this on his own body to rapidly heal wounds. However, as Rarity notes during their battle, this ability is tied both to his available reiatsu and the severity of the wound. As such, when she goes unleashes her final attack on him, she not only does it when he's already heavily exhausted and injured to the point he can't quickly heal, but goes for a fatal wound through his chest.
  • The Storm King's Resurreccion can heal attacks from Tempest's Bankai and combined attacks from all four Dark Hunters' kaiju forms. However, as it is tied to his reiastu levels, it does have limits as he takes more damage and expends more energy.
• Fate of the Clans (Fate Series & K):
  • A trait of all Servants. How fast they can regenerate depends on the severity of the injury and the amount of mana they have, a flesh wound typically closed in a second. The wound has to be cleared of any foreign objects to heal, though. Even lost or destroyed organs or body parts will grow back.
  • Cú Chulainn (Prototype Lancer) Alter has his jacked way up due to his mana being supplied directly from the Greater Grail. He's able to heal the damage his Noble Phantasm causes to his body, which really rips him up internally, in less than a second.
• Fate/Parallel Fantasia: 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.
• Not the intended use (Zantetsuken Reverse): As said in the third chapter, the Ouija Table soul gives Soma the ability to heal faster than he can be burned:
  He forced his burning body onto Julius's chair and activated his Ouija Table soul. The fire kept on burning him, but his body recovered faster than it melted.
• Origins (Borderlands 2 & Mass Effect & Star Wars): Sarah has this likely due to a combination of Siren and Force powers, as do the Flood, having incorporated bacta into themselves. Some ships use digistruction to much the same effect.
• Voyages of the Wild Sea Horse (One Piece & Ranma ½): This is one of the special powers of the Mythic Zoan-class Devil Fruit known as the Bat-Bat Fruit, Model Type: Vampire. Minutes after eating it, Nabiki Tendo gets Impaled with Extreme Prejudice by a mutant insect. She Offhand Backhands it so hard that it is shattered into pieces, then rips out the wickedly barbed limb, causing the gaping, ragged hole to seal itself within a few moments.
• Yugioh EQG (My Little Pony: Equestria Girls & Yu-Gi-Oh!): Downplayed. Sunset Shimmer's ace monster Solar Flare Phoenix has the ability to double her life points when it is special summoned to the field, as long as her life points are at 2000 or lower. Because it is a Pendulum monster it can be summoned as long as Sunset has the right scale and keep her life points high. Her Synchro monster Solar Phoenix Rebirth has the ability to increase her life points by 1000 once each turn.

Dungeons & Dragons

• Both Haara and Spectra have ways to magically heal themselves or others. Haara has Healing Hands while Spectra can target people with Healing Light from afar.

Godzilla / King Kong / MonsterVerse

• Abraxas (Hrodvitnon): Monster X has an unearthly ability to rapidly heal any damage their body takes in under an hour, which is inherited/retained from Ghidorah, although Monster X can't quite efficiently replace severed tissue like Ghidorah can. It's also confirmed in this story that Ghidorah's regenerative capabilities extend to regrowing itself entirely from just a single severed head, although it takes much longer than Ghidorah's body regrowing a head in the movie did. The Many, also derived from Ghidorah, can repair damage to themselves in seconds.
• Godzilla Neo: All Godzilla species have this trait. However, Ghost Godzilla has displayed its full potential. After being destroyed by the Yamato Guardians, all that remained of the beast was his heart. However, as the scientists continued to examine it, the heart has begun growing and Ghost Godzilla returned as implied in the original movie.
• Kaiju Revolution:
  • All Kaiju have this to an extent, but Godzilla and Anguirus both have extraordinary regenerative abilities thanks to the evolutionary arms race between their two species.
  • Frankenstein has an exceptionally potent regeneration that makes up for his relative frailty for a kaiju and pieces of him might even be capable of growing into new creatures, which is why it's advised to avoid bombing him.

Grandmaster of Demonic Cultivation: Mo Dao Zu Shi / The Untamed

• Shifters in The Beast Of Gusu have this. It’s better shown during Wei Wuxian and Xue Yang’s fight in Chapter 3 of “Unstoppable”, during which they maul each other and begin to heal just as fast.

Invader Zim

• Becoming a True Invader:
  • All Fefians have an extremely effective healing ability, able to regenerate from basically anything except being digested, thus rendering them virtually immortal.
  • The Employer later installs a powerful healing ability into his soldiers by stealing genetic material from the Fefians.
• Invader Zim: A Bad Thing Never Ends:
  • Irkens have a limited one provided by their PAKs. At some point prior to the story, Zim developed a "healing mist" that speeds up the process, being capable of near instantly repairing any wounds.
  • Lex heals at a rapid pace that is disturbingly quick even by Irken standards.
• The Smeet Series: The reptilian Sobrekt have this ability, from healing minor wounds in seconds to regenerating missing limbs via hibernating inside special capsules filled with a liquid that entices their body cells to renegerate the missing part of their bodies. Ilk, Red's daughter, gained the ability after being cured from Drilo's Disease due to the sobrekt flower used in the cure.
• Zim the Warlord: Irken Reversion: Irkens who have undergone the Reversion now have an emergency super-healing ability in case of extreme injury. However, it only works if the organ that stores the blood their new dart tongues drain from others is full, as that's what powers the effect.

Jackie Chan Adventures

• Queen of All Oni: Jade has a healing factor as part of her new powerset, as well as the Horse Talisman from canon (see Western Animation).

Kill la Kill

• Lost, Found: Nui and Ryuuko have this, due to being experimented on, the former getting better quickly after breaking her wrist and getting a skull fracture. However, while the latter did take and shrug off hits from a mountain lion and a bear, Ryuuko's healing factor mostly saved her from external injuries, not internal ones and those internal injuries complicated her being sick.

The Locked Tomb

• it's about the bones: Harrow's healing actually works correctly this time around, because she's a perfect Lyctor despite having come at it from the wrong way around. Furthermore, it's implied that Gideon had her own when she was alive. When she gets her body back, she sees the giant hole in her chest and fixes it in a blink.

Lost Girl

• Mad World: Lauren develops one. 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 case of Blessed with Suck 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.

My-HiME

• Windows of the Soul: Gives all the Hime a healing factor and heightened reflexes (to explain how Shizuru could Dodge bullets in the series). It's not as exaggerated as a character like Wolverine, but injuries that would ordinarily be permanently crippling can instead be healed completely after a reasonable amount of time. (A knife wound heals in days without scarring, and a gunshot that should have made an arm useless is healed after s few weeks).

My Little Pony

• Daylight Burning: Alicorns can regenerate injuries extremely quickly. While in Celestia's body, the Nightmare takes only a few seconds to recover from having most of her flesh burned away by dragonfire. At the climax, the characters need to put absolutely everything that they can find into pummeling her down not because they expect it to achieve anything in the long term, but because doing this outpaces her healing just barely enough to give time for the Elements of Harmony to be retrieved and used.
• Fallout: Equestria:
  • In the original series, 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. Steelhooves, being a Canterlot Ghoul (see Pink Eyes, below) has a much more powerful healing factor, but it rarely comes up because he's constantly encased in Powered Armor.
• Fallout: Equestria Recursive Fanfiction Fallout Equestria: Pink Eyes: The lead character Puppysmiles is a 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.
• Fallout: Equestria Recursive Fanfiction Fallout: Equestria - Project Horizons:
  • Taken up to eleven with Rampage, whose Healing Factor makes her flat-out immortal. She has recovered from extensive Taint mutation, headshots, being beheaded, being blown up, leaping into a woodchipper and even being completely 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 Immune to Drugs, 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 Death Seeker, 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 Magitek cybernetics. Even her mechanical parts regenerate, if supplied with — ingested - scrap metal.
• The Immortal Game: This part of the earth pony magic, alongside Super-Strength. An alicorn, who has world-class earth pony 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 Luna. Combined with magic-enchanted armor and Super-Strength, she's a borderline Nigh Invulnerable.
• Pony POV Series: Alicorns have the ability to regenerate very rapidly, having The Power of Creation. 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 Dark World arc, the Dark World Mane Six have this ability thanks to their Elements of Chaos acting as a Soul Jar. So long as it's not destroyed, they're rapidly heal from any damage taken. This makes Rarity's Healing Hands power more practical, as to do she takes a team mate's injury into herself.

Pokémon

• Pokémon Reset Bloodlines: In this setting, one of the general abilities Bloodliners have over normal humans is a heightened resistance to injury and a faster recovery rate from wounds, even sometimes sparing themselves from scars. There's one particular example of a Synthesis Bloodliner who is able to easily heal just by being under the sunlight.

Puella Magi Madoka Magica

• Resonance Days: Because it's set in the afterlife, all characters in the setting have Complete Immortality and will regenerate from any injury very quickly, though tearing someone up so much that there are only miniscule pieces left will obviously take longer. Magical Girls who had an especially strong healing factor in life also carries that over to the afterlife, letting them regenerate faster than normal. Word of God is that Sayaka, who's healing factor in life let her recover from being torn to pieces, would regenerate so fast that cutting her head off, normally an injury that takes a while, would result in another one regrowing "like a pez-dispenser."

Sonic the Hedgehog

• Sonic X: Dark Chaos: Tails gets one when he is infected by Shroud parasites. 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 literally falling apart, which starts to heal him, which makes him fall apart again...

Whateley Universe

• Casey Steele: This, known In-Universe as "Regen" — short for "Regeneration" — is assumed by one of the listeners of Casey's story to be how she survived being a Human Sacrifice.

Unsorted

• The Tainted Grimoire: Dread Raven combines this with The Undead to achieve Immortality.
• Golden Dawn: Lost Sunrise: 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. 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.
• Imaginary Seas: The denizens of the Atlantis Lostbelt have all been given Demeter's Klironomia, Ambrosia. As a result, they have the ability to regenerate from most wounds, only requiring a healing coma in the case of severe injuries, and are The Ageless. Percy can also give himself these same healing abilities by wearing the Golden Fleece.
• Project Riribirth: In the backstory, Riri fights against a large monster who has a very powerful Healing Factor, to the extent that Riri destroys its hand and it almost immediately grows a new one. The fight goes... poorly for Riri.
• The Power of the Equinox: After Twilight Sparkle transforms into Dimmed Star, this is one of her new abilities. She can regrow her limbs and eyes, and even regenerates herself after Princess Celestia blasts her to pieces. However, when Dimmed Star tests out this ability, she discovers that her regeneration ability does slow down when overloaded, leaving her vulnerable.
• EVA Sessions: Someplace Vast and Dry: Unlike her canon self, Rei can rapidly heal from cuts and bruises within minutes, an effect first discovered when she gashed her nose against a coffee table as a toddler; Kyoko theorized she could theoretically even regenerate missing limbs or organs, although this has yet to be examined in the story so far.
• Son of Sparda D×D: Dante has this like canon. He shrugs off impalement and all manner of projectiles like they're not even there. He even muses that he could make a fortune on the black market selling his organs since they'll just grow back anyway.
• The Secret Return of Alex Mack: Riley gains regeneration "somewhere between Wolverine and Spider-Man" after being exposed to the T-virus.
• With This Ring: Several characters have various levels of this.
  • The Danner formula gives fast healing that requires the person to eat more, especially protein. Beautia Sivana goes from "melted fat dripping off fingers" to healthy within a few minutes by eating an entire cassoulet. The Children of Dawn died in a very unpleasant fashion when they became sick, and their bodies tried to heal, but they couldn't keep down the food they needed.
  • The Renegade protagonist turns himself into a New God, making his whole body infused with powerful magic. He loses the ability to rebuild his body with his power ring, but gains powerful regeneration — especially if he has access to a source of raw magic — along with Super-Strength, Super-Toughness, and immunity to poison and disease. After conquering an entire planet, he's able to rapidly regenerate lost thumbs without even needing extra magic.
  • A robotic example: Mister Atom is able to rapidly repair himself by absorbing radioactive emissions.
