->''"I don't want to achieve immortality through my work. I want to achieve it through not dying."''

One of the oldest of human desires is to counteract [[WeAreAsMayflies the fleeting nature of our short human existence]]. Eternal life is ingrained in the collective human consciousness, having been present in literature and myths for [[OlderThanDirt as long as they've been around]]. Literally. ''Literature/TheEpicOfGilgamesh'' (the oldest heroic epic known to the modern world) is, in large part, about the titular character's search for a way to live forever.

Of course, having been around for so long, Our Immortality Is Different, and comes in several flavours. These tropes are not mutually exclusive; there's plenty of room for overlap.


* '''CompleteImmortality''' - A character simply ''can't'' die, ever.
** This trope = The Ageless + NighInvulnerability UpToEleven

* '''Retroactive Immortality''' - A character ''can'' die, but won't ''stay'' dead.
** BornAgainImmortality - if the character's mind or spirit is transferred to a new-born child, as in traditional reincarnation.
** ResurrectiveImmortality - if the character simply comes back to life uninjured, exactly as they were.

* '''Biological Immortality''' - A character is immune to the ravages of time, although usually still mortal to physical injury.
** TheAgeless

* '''Force of Will'''
** PurposeDrivenImmortality

* '''Spare Bodies'''
** BodyBackupDrive
*** BrainUploading
** GrandTheftMe
*** BodySurf
** FightingAShadow

* '''How to become immortal?''' - Methods by which a mortal character can actively cheat death. Key word being ''actively'', once the method is stopped or reversed, they either die or become mortal again.
** FountainOfYouth
** ImmortalityInducer
*** SoulJar
*** HeartDrive
** LifeDrinker
*** BloodBath

* '''Incomplete Immortality'''
** AgeWithoutYouth
** TheUndead
