Regeneration

Summary
Regeneration (also known as healing factor) is a term given when a particular character can heal from wounds at an accelerated rate, even regenerating from wounds that would be lethal to normal humans. Regeneration has different levels.

Low levels of regeneration are essentially just faster natural healing, so a wound that could take weeks to heal would take days, hours, or even seconds. More advanced forms of regeneration can regrow lost limbs, organs, going all the way up to regenerating from decapitation, being blown to pieces or vaporized, and even complete physical destruction.

Types
Low: Faster healing ability for normal wounds. In machines and vehicles, this would be regenerating basic exterior damage.

Mid-Low: Able to heal wounds that would normally leave large scars. In machines and vehicles, this would be regenerating damage that would normally leave large dents and openings.

High-Low: Able to regenerate some severed minor body parts, such as fingers, or of reattaching arms and legs. In machines and vehicles, this would be regenerating some interior damage, and some minor critically damaged or destroyed parts.

Low-Mid: ''Able to regenerate limbs/fatal wounds. Still die from decapitation. In machines and vehicles, this would be regenerating minor parts and more extensive internal damage.''

Mid: Able to regenerate from decapitation. In machines and vehicles, this would be regenerating from the destruction of critical parts such as the engine.

High-Mid: Able to regenerate from being blown into pieces.

Low-High: Able to regenerate from a puddle/drop of blood, or a small piece of your body.

Mid-High: Able to regenerate from being vaporized/dust.

High: Able to regenerate from a single molecule/atom/particle.

Low-Godly: Able to regenerate as long as your disembodied consciousness exists, such as in the form of your soul or mind, or from other realms.

Mid-Godly: Able to regenerate even after every aspect of the mind, body, soul, and consciousness, are erased from existence.

High-Godly: Able to regenerate even if your existence is erased and the reality you are within is destroyed.

True Godly: Able to regenerate from being erased on a level beyond the confines and concept of dimensions themselves.
