Immortality

## Summary

**Immortality** is the ability to simply not die by natural means for any number of reasons, ranging from simply having no limit to your lifespan, being able to regenerate from wounds that would normally be lethal, or being protected by a higher being, among other possible reasons. It should be noted that no Immortality is truly perfect, and no matter how much a character's immortality is hyped up within their own setting, it is very, very unlikely that they are truly completely unkillable when matched up against characters from other fictions.

## Types

**1: Eternal Life:** Characters gifted with this type of immortality cannot die from natural causes, such as old age or conventional illness, but can be killed by unnatural causes. To clarify, this type of immortality can include both those who do not age at all, and those who still grow old, but will never die of old age. However, in the case of the latter it should be made clear that this is not just Longevity, as characters with that ability will eventually die of old age, as opposed to Eternal Life, for which dying of old age is not possible.

* **Examples:** Najimi Ajimu (Medaka Box), Androids and Cyborgs in many fictions

**2: Resilient Immortality:** Characters with this degree of immortality can indefinitely survive injuries that would otherwise be lethal to a normal person, without needing to heal. This type of immortality can have different levels of effectiveness and can be bypassed, for example, by causing extremely severe wounds or the complete destruction of the body or specific parts of it, such as the head, etc.

* **Examples:** Frieza (Dragon Ball), Hidan (Naruto)

**3: Immortality via regeneration:** Characters with this type of immortality can simply regenerate from wounds that would normally be lethal, though its effectiveness depends on the degree of the regeneration.

* **Examples:** Featherine Augustus Aurora (07th Expansion Series), Rimuru Tempest (Web Novel)

**4: Immortality via reincarnation or resurrection:** Characters that are immortal because, whenever they die, they will simply reincarnate within another body or resurrect themselves at a later point in time.

* **Examples:** Natsuki Subaru (Re:Zero kara Hajimeru Isekai Seikatsu)

**5: Deathless Immortality:** *Characters who exist unbound by conventional life or death, or do not exist at all, and thus cannot be traditionally killed. Typically, abilities such as Existence Erasure are needed to destroy them.*

* **Examples:** Kaguya Houraisan and Fujiwara no Mokou (Touhou Project)

**6: Parasitic:** The character is able to attain a sort of immortality by abandoning bodies whenever necessary to transfer their consciousness to another body, whether they are possessing someone else or switching to a backup body.

* **Examples:** The Lich (Adventure Time), Dio Brando (JoJo's Bizarre Adventure), Orochimaru (Naruto)

**7: Undead:** Characters who cannot die due to technically being already dead, often overlapping with other forms of immortality.

* **Examples:** Most of undeads and zombies in fictions

**8: Reliant Immortality:** The character gets benefited by 1 or more other types of Immortality as long as a certain being, object, place and/or concept or more may grant them those benefits, losing them otherwise. What exactly a user is reliant over, the benefits given from it, and how the process of the ability operates must be explained. Simply having some weakness that will kill a character when exploited doesn't qualify if it doesn't grant a form of Immortality, and also having other powers that do grant Immortality but are unrelated to that weakness does not count as well. It is discouraged to list this type if it would be redundant due to the same power already being described in another ability of the profile.

**9: Transcendental Immortality:** Characters whose true selves exist independently from the plane where they can be killed.

* **Examples:** Pennywise (Canon)

## Notes

1. We considered that characters with only levels of Regeneration lower than Mid do not have Type 3 of Immortality since they still can be killed easily by common attacks or damages.
2. Claim that someone can not be killed on matter what without proving his/her immortality's level is considered No Limit Fallacy.
