Immortality

Immortality is the ability to, through various means, not perish. This could be through Regeneration, Agelessness, or any other means which leaves a character unable to perish.

Immortality in the form of an Afterlife is not considered to be any true form of Immortality in regards to this site.

Types
Ageless Immortality: This is Immortality through a cessation of senescence, that is to say, they do not physically age, but can die through other means such as having their body damaged beyond repair. This is often confused with Longevity, and sufficient reasoning must be provided that Ageless Immortality is the correct assessment, and that it is not actually Longevity.

Regenerative Immortality: This is a form of Immortality which arises from the ability to regenerate from any wounds which would normally prove fatal to a living organism. Not all Regeneration is enough to be counted as Regenerative Immortality, but only regeneration from that which would kill any other being, such as decapitation, horizontal bisection, or so forth. The degree to which this Immortality extends must be noted.

Deathless Immortality: This is a form of Immortality which applies to those who attain Immortality through being unbound by conventional life or death, leaving them unable to be traditionally killed.

Reliant Immortality: This is a form of Immortality wherein a being cannot perish as long as a certain being, entity, or concept still exists. The exact nature of this form of Immortality varies wildly between characters, and must be explained in detail on a character's page.
