Ways of defeating something with a Healing Factor
Fighting something with a Healing Factor is very difficult, usually requiring extreme force, special powers or tools, or clever tricks. Ways of dealing with Healing Factor are:
- Playing with Fire: Fire can cauterize wounds to prevent regeneration
- Kryptonite Factor: A special weapon or element, whether it be magical or scientific, can often do harm while ignoring a character's Healing Factor. Sometimes, this weapon or element will be connected to how the Healing Factor came about in the first place.
- Excessive Damage: Healing Factor may have a limit of how much damage can be regenerated
- Complete Annihilation: Given situations like From a Single Cell, that is the only way to deal with such
- Achilles' Heel: There may be a specific place, such as the head, where something is the most vulnerable
- Preventing body parts from reattaching: Something that can reform itself can be defeated or severely hampered if a single body part is prevented from reattaching to the rest of the body
- Inflicting a Wound That Will Not Heal
- Stealing the Healing Factor
Examples:Anime and Manga
- Dragon Ball features quite a few characters with Healing Factors who have had to be stopped.
- Namekians are the original regenerators in the franchise. They can heal dismembered limbs so long as their heads remain intact, although if they sustain enough damage they can die with their whole bodies remaining.
- Cell is the Trope Namer for From a Single Cell, he can regenerate from any amount of damage so long as his "core" (a special cluster of cells in his head) remains intact. So the one way to beat him is to disintegrate him all at once.
- Majin Buu is an even more insane example, being capable of regenerating if even a single atom of him remains. The only known way to kill him is a Spirit Bomb empowered by the population of everyone.
- Future Zamasu used the Super Dragon Balls to wish for immortality and no matter how much damage he takes he will always keep healing. He retains his immortality as Fusion Zamasu, after fusing with Goku Black, although it was gimped so that his body could be destroyed. However, free of his body he Ascended to a Higher Plane of Existence and assimilated with the universe. The only way to beat such an Eldritch Abomination was to summon Zen'o to erase the multiverse from existence.
- One Piece: Buggy the Clown, who is capable of Detachment Combat, was initially defeated by Nami stealing most of his body parts before he could reassemble himself.
- My Hero Academia: Endeavor defeats a Noumu with a "Super Regeneration" Quirk by making his flames hot enough to turn blue and carbonize the head off.
- One Wolverine story has Sabretooth gloating that he actually thought up the one way to beat a Healing Factor... as his foot is holding Wolverine's head underwater.
- Deadpool's Walking Arsenal includes a sword made of carbonadium, a radioactive element capable of negating Healing Factors. This allowed him to kill everyone in one story line including all of the quick healers.
- The primary villain of Heavy Metal 2000 stumbles upon a fluid that can grant him Resurrective Immortality, provided he takes regular doses. Tyler goes on a quest for the source after attaining the key. He ends up squished under a huge stone door where regeneration would avail him naught. Further, The Mole unmasks himself, and attains access to the wellspring of eternal life. However, once the huge stone door closes, he's trapped in that chamber. As The Hero remarks: "Forever is a long time to spend all alone."
- The beginning of Hercules Unchained has a fight against Antaeus, who recovers from all injury whenever he touches the ground. Unlike the original Greek myth, Hercules defeats Antaeus by throwing him into the sea.
- In The Wolverine, Wolverine has a bio-mechanical healing suppressant device implanted in him, thanks to Viper. For a large portion of the film, Wolverine finds he is no longer healing and needs to have his wounds stitched up.
- In Logan, it's finally revealed that the long term effects of adamantium exposure is healing factor degeneration. Wolverine has had adamantium bound to his skeleton for years and isn't healing as well as he could. Ultimately, his healing factor is completely compromised and he dies.
- Animorphs: Morphing normally heals all injuries, but there have been notable exceptions, few of which are explained beyond Drama-Preserving Handicap: suffering Mode Lock (Tobias is stuck in hawk morph at the beginning of the series so an injury would be particularly devastating, when the ability is restored he can heal but still has to live as a bird), a genetic disease (a crashed Andalite refuses to fight because the disease stays with him when he demorphs, while another is allergic to the morphing process and cannot repair his severed tail), time travel (Tobias breaks his wing while in the Cretaceous and can't restore it), and possibly old age (Jake ends up in a Bad Future where Rachel is a complete wreck in a wheelchair, with no indication that she'd lost her morphing ability).
- Classical Mythology
- One of Hercules' task was to kill the Hydra. which he succeeded when his nephew Iolaos started to cauterize the stumps with his torch.
- The giant Antaeus challenged travelers to a wrestling match to the death, without mentioning that every time he was in contact with his mother the Earth (i.e., thrown to the ground), his health and energy were completely restored. When Heracles came along, he solved the problem by hoisting Antaeus in the air with one hand and strangling him with the other.
- Often werewolves are given a healing factor that is neutralized by silver.
- The Lambton Worm is an English legend about a dragon which kills by constriction and is difficult to kill because it can re-attach parts of its body that are cut off. It is eventually killed by a Prince who lures it into the River Wear while wearing armour forged from razor blades - the blades hurt the beast when it tries to constrict him, and the river flow washes its severed body parts away.
- Dungeons & Dragons
- Trolls in Dungeons & Dragons possess a Healing Factor which can only be overcome by injuring them with fire or acid.
- 1st Edition Deities & Demigods Cyclopedia, Greek Mythology section: each minute the giant Antaeus is in contact with the ground, he heals all damage and gains 25 additional Hit Points. The hero Heracles (Hercules) defeats him by lifting him off the ground and inflicting damage on him while doing so.
- 1st and 2nd Edition. When someone wears a Ring of Regeneration, they can only be prevented from regenerating if their body is totally destroyed by fire or acid.
- In Big Eyes, Small Mouth, any special attack with the No Regeneration modifier cannot be healed using the Healing or Regeneration attributes, and has to be healed naturally. The Incurable modifier is a stronger version of this, and basically inflicts Wounds That Will Not Heal.
- Pokémon: The move Heal Block prevent the target Pokemon from healing, whether by its own moves, abilities, terrain, or items (for the last one, only Generation V and onward).
- Resident Evil 4: Regenerators and Iron Maidens can only be killed by using a special scope on a rifle to aim at specific places were the Las Plagas parasites are inside their bodies.
- A few particularly powerful wizards in Arcanum have the ability to summon a regenerative cocoon at the moment of death, healing their wounds and increasing their lifespans. The Vendigroth Device is a weapon which was specifically designed to combat this technique, and exploits the fragile balance between magic and science to invert the cocoon and make it rip the mage apart instead.
- The Serpent boss in Golden Sun: The Lost Age has a regeneration ability which lets it recover about 2/3rds of its max hitpoints at the end of every turn. However, the area above it has a series of light puzzles which, if completed, allow you to shine up to four beams of light onto it, potentially cutting its healing to a measly 30hp/turn instead.
- Warcraft III:
- The expansion introduced several freely available healing items that restore health and/or mana over time (Scroll of Regeneration, Clarity Potion...) with the caveat that the effect ends as soon as the unit takes damage.
- Inverted with the Phoenix and Destroyer units, who have negative health and mana regeneration respectively. The Phoenix respawns every time it dies (unless its egg is destoryed), while the Destroyer has several spells that let it eat mana or status buffs to empower its attacks.
- One-Punch Man: Melzargard's head has a small marble-like brain which allows them to regenerate endlessly. If a marble is destroyed, the associated head melts instantly, and Melzargard dies once they're all destroyed. This is mitigated somewhat by the fact that he has multiple heads and can freely move his brains within his body. However, his regeneration always begins with his heads, meaning that the brain can be easily found if his body is completely destroyed and forced to regenerate from scratch.
- The Order of the Stick: Belkar accidentally defeats a hydra by chopping off its heads until there isn't enough blood to supply all of them. A passing goblin notices the comatose hydra and sets up an enormously successful barbecue shack thanks to a never-ending supply of meat.
- In Star Vs The Forcesof Evil, Queen Moon used black magic to neutralize Toffee's healing factor, making him unable to regenerate.
