Regeneration

==Summary==
Regeneration, often referred to as a healing factor, is the ability to passively heal oneself from wounds at an accelerated rate, with many characters proving capable of regenerating from wounds that would be lethal to normal humans.
It has several different levels that range in potency from what is essentially just faster natural healing to being able to regrow limbs or organs, or even a severed head.
Higher levels allow characters to regenerate from even more severe wounds, such as being blown to pieces, reduced to a single cell, vaporization, and even complete physical destruction and beyond.
Instances of characters being wounded and inexplicably recovering off-screen should not be taken as evidence of regeneration unless supported by further context. This is due to reasons ranging from the possibility of off-screen treatment to continuity errors. See this thread for reference.
Take note that although by default characters will recover from lower degrees of damage than their regeneration levels, if it is shown to not consistently be the case, often by not triggering until a certain level of damage has been reached, that should be specified in each respective case.
Statements or feats of regeneration in which characters are able to survive as long as a part of their existence, such as their souls or minds, remain intact, or that involve the regeneration of a non-physical aspect of the body while the body itself remains intact, do not warrant godly levels of regeneration due to involving resurrection rather than the complete destruction and reforming of both the physical and non-physical aspects of a body, which is a fundamental requirement to qualify.
If a character's ability to regenerate is limited to certain conditions, the character page should provide a detailed explanation of those circumstances. If the character can only regenerate from damage that is covered by a higher type of regeneration, but not from damage that should be included in a lower type, the page should list the lowest type for which all qualifiers are fulfilled, or none if not even Low Regeneration is fulfilled. The extent of the regeneration should then be explained in an additional note.
For example, if a character can regenerate from having their head destroyed but not from having their heart destroyed, they would be listed as having Low-Mid regeneration. The page would explain that the character can regenerate from head damage as long as their heart remains intact. If a character can only regenerate damage to their soul but not their body, their page would explain that they have soul-specific regeneration and list no type. Similarly, if a character can regenerate their concept but not their body, their page would list them as having regeneration with an explanation that it is concept-specific and has no type.
==Types==
Low: Merely an accelerated healing ability for normal wounds, allowing the character to heal wounds that would normally take days, weeks, or even months much more quickly, sometimes even in just seconds. For machines and vehicles, this would just be regenerating basic exterior damage.
*Examples: Naruto Uzumaki (Naruto), Nnoitra Gilga (Bleach), Tanjiro Kamado (Kimetsu no Yaiba)
Mid-Low: The ability to heal wounds that would normally leave large scars, such as severe burns or deep injuries. For machines and vehicles, this would be regenerating damage that would normally leave large dents and openings.
*Examples: The Courier (Fallout), Hercules (Marvel Comics), Batman (Post-Flashpoint) (DC Comics)
High-Low: The ability to regenerate severed fingers, toes, or ears, minor organ damage, and even potentially reattach lost limbs. For machines and vehicles, this would be regenerating some interior damage, along with some minor critically damaged or destroyed parts.
*Examples: Wally West (DC Comics), Malekith (Warhammer Fantasy), Adam (Neon Genesis Evangelion)
Low-Mid: The ability to regenerate lost limbs, limited brain damage, and even severe organ damage or destruction, including traditionally fatal wounds and disembowelment or horizontal bisection. For machines and vehicles, this would be regenerating minor parts and more extensive internal damage.
*Examples: Shirou Emiya (Fate/stay night), Starjun (Toriko), Cole MacGrath (InFAMOUS)
Mid: The ability to regenerate from decapitation or severe brain damage. For machines and vehicles, this would be regenerating from the destruction of critical parts, such as the engine.
*Examples: Sayaka Miki (Puella Magi Madoka Magica), Aza'gorod the Nightbringer (Warhammer 40,000), Hood (My Hero Academia)
High-Mid: The ability to regenerate from being blown/cut to pieces, brain included, or from a small piece of the user's body, such as a finger, or the heart.
*Examples: Dio Brando (JoJo's Bizarre Adventure), Spawn (Image Comics), The Protagonist (Cruelty Squad)
Low-High: The ability to regenerate from having no solid parts of the body remaining. This can range from a puddle or drop of blood to even a single cell. For robots and machines, this can also include regenerating from a liquid state.
*Examples: Father (Fullmetal Alchemist), Jason Voorhees (Friday the 13th), Mahito (Jujutsu Kaisen)
Mid-High: The ability to regenerate from having all biology completely incinerated. This includes being reduced to ash, dust, smoke, vapor, or plasma.
*Examples: Majin Buu (Dragon Ball), Dark Matter (Kirby), Deadpool (Marvel Comics)
High: The ability to regenerate from a few scattered or lone molecules, atoms, sub-atomic particles, or pure physical energy units.
*Examples: The Sentry (Marvel Comics), The Beast (InFAMOUS), Don Slime (Toriko)
Low-Godly: The ability to regenerate from the complete physical destruction of the user's body, instead restoring it from their disembodied consciousness, whether that be their soul, mind, some other non-physical aspect of themself, esoteric or metaphysical energy, or something else.
*Examples: Alucard (Hellsing), Knives Millions (Trigun), Captain Atom (DC Comics)
Mid-Godly: The ability to regenerate from the complete erasure of one's body, mind, and soul.
*Examples: Fujiwara no Mokou (Touhou Project), Sosuke Aizen (Bleach), Dark Schneider (Bastard!!)
High-Godly: The ability to regenerate after the erasure of body, mind, soul, and at least one other fundamental aspect of a character's existence. Such an aspect could be their place in the narrative, their history, their information (Type 2), their concept, et cetera. For any aspect to qualify, destruction of that aspect must cause erasure of the character in some form and it must be shown that the character cannot exist without that fundamental aspect existing as well; in addition it must not be something that would ordinarily be restored by regenerating body, mind, or soul. As such, type 3 concepts must be evaluated with care and aspects which are not sufficiently expanded upon to make a judgement will not to qualify.
*Examples: Rimuru Tempest (Tensei Shitara Slime Datta Ken), Lavos (Chrono), Dracula (Castlevania)
Note: For High-Godly Regeneration, be sure to specify which aspect(s) the characters with this ability have been shown to regenerate from within their profile pages. For example: "High-Godly; Plot. Returned from having their Narrative Structure erased."
