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.
Additional Explanations:
- 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.
- 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: Mako Stride with Weakened Kaedna (Heir of Light)
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: Sakamaki Ryuichi (Fairy Tail Fanon), Linx Rifelson (Gyrohem)
High-Low: The ability to regenerate severed fingers, toes, or ears, minor organ damage, eye destruction 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: Aikkon and Yasai (Dragon Soul), Kamala Khan (Avengers Alliance), Prime Tomato (The Shoobieverse)
Low-Mid: The ability to regenerate lost limbs, and even from 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 with Avalon, Power of Three (LOT) (Tales of nephilim), Thrasel Shravrek, The Vagrant, and other Sentinels/Chosen (Crestseal), Cronus, Zak Fann (Ovenverse),
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: Lord Hansel (The Edgyverse), Wolverine (Avengers Alliance), Whisper (Stick Shenanigans)
High-Mid: The ability to regenerate from being blown / cut to pieces, or from a small piece of the user's body, such as a severed head, a single organ, or a finger.
- Examples: Dalemens (JOD`S) (Tales of nephilim), Remilia Scarlet (Koumajou Densetsu), Ruler (Nameless), Experiment 88 (The Shoobieverse)
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: The Blood Drenched Emperor, Mizma (Supreme Duelist Stickman)
Mid-High: The ability to regenerate from having all biology completely incinerated. This includes being reduced to ash, dust, smoke, vapor, or plasma.
- Examples: Ren (Therlishia Saga), Hulk (Avengers Alliance)
High: The ability to regenerate from a few scattered or lone molecules, atoms, subatomic particles or even smaller bits, as long as there is at least something left of the body.
- Examples: Ensyn Shenlong (Dragon Soul), Titans (Olethros), Poker The Poker
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: NUMEN, Doctor Strange (Avengers Alliance), Lantern Ring users (Knights of Justice)
Mid-Godly: The ability to regenerate from the complete erasure of body, mind, and soul. Given that machines and other beings that have no minds or souls doesn't have these aspects, the level of destruction on Low-Godly level will count as Mid-Godly for them.
- Examples: Kagami Shiro, Tendou Shiki, The Corpse Mounted Emperor
High-Godly: The ability to regenerate after the erasure of body, mind, and soul, along with at least one even more fundamental aspect of a character's existence, such as their place in the narrative, their entire history, the underlying information (Type 2) or concept(s) (Type 1 or 2, but only very rarely 3, if there is strong evidence of being similar to the former types in terms of how hard it is to regenerate from them) needed for them to exist.
- Examples: Tenebris (Kingdom Hearts IV), Kozan (Venefica Chronicles), Divine Souls (Venefica Chronicles)
