Wolverine regenerating after being blown up and reduced to just his skeleton.
Regeneration, also known as a healing factor, is the ability to automatically heal from wounds or damage that would otherwise be lethal to ordinary humans. There are multiple different levels of regeneration, each which effect how severe of damage the user can regenerate from, or how long it takes for it for the users to be fully healed. Lower levels allow for regenerating or reattaching dismembered limbs or even severed heads, higher ones from atomization and even complete physical destruction.
Levels of Basic Regeneration[]
- Minor: Only allows for regeneration from minor wounds, scars, or bruises, or otherwise basic exterior damage.
- Examples: Batman, Spider-Man
- Major: Allows for regeneration from severed limbs and damage to vital organs, even severed heads in some extreme cases.
- Examples: Dante (Devil May Cry), Deadpool, Dio Brando
- Extreme: Allows for regeneration from utter decimation so long as there is still a remnant of them remaining. I.E., being able to regenerate as long as your skeleton is in tact, or in more extreme examples, from merely a finger.
- Examples: Wolverine
- Atomic/Cellular: Allows for regeneration from an atomic or cellular level, being able to reform themselves even if their physical forms are outright destroyed.
- Low Godlike: The ability to regenerate after being completely removed from existence, including mind, body, and soul.
- Godlike: The ability to regenerate from being erased beyond dimensional confines or concepts.
