History Main / ImmortalityInducer

* In ''StargateSG1'', Goa'uld sarcophagi are best described as {{Autodoc}}s, but they're so effective that they can ''raise the dead''. The System Lords are thousands of years old thanks to them. Shame about the [[AGodAmI side effects]].

* In the Old Norse "Literature/TaleOfNornaGest", the magic of a norn makes Norna-Gest immortal so long as a certain candle is not destroyed.

* VandalSavage was a Cro-Magnon man named Vadar Adg who found a strange meteorite that fell to Earth one cold night. He fell asleep near it, being bathed in its rays during the night, and he woke up an immortal being. However, meteorite's effects aren't permanent; Vandal occasionally needs to eat the flesh and organs of his own descendants to maintain his immortality.

* In RobertEHoward's ''ConanTheBarbarian'' story "The Tower of the Elephant", Yara is said to be centuries old, and immortal because of his [[MineralMacGuffin gem]], the Heart of the Elephant.

* In Chinese mythology, the Peaches of Immortality grow in the garden of the Jade Emperor of Heaven and are given to gods, sages and others deemed worthy of them.

* In NorseMythology, the gods maintain their immortality by the eating of [[HowDoYouLikeThemApples golden apples]] cultivated by the goddess Iðunn. You might be noticing a pattern here.

* In ''LordOfTheRings'', this is one of the things the One Ring can do. Gollum's unnatural age is thanks to it. The Nine for the Nazgul also serve this function.

* Both Yukiko and Liselotte Werckmeister from ''11eyes'' share the same immortality that comes with an rapid HealingFactor and [[TheAgeless the inability to age]]. It is revealed that the Voidstone is the source of the immortality and separating it from the host will disable that immortality.

* In Megan Whalen Turner's ''The Thief'', Gen ([[ExactlyWhatItSaysOnTheTin the titular character]]) is recruited to help find a stone that grants immortality to whoever is wearing it. [[spoiler:After he steals it, he hides it in his hair and attempts to escape, but is caught up in a fight and stabbed in the chest. When the sword is removed Gen describes it as feeling as though his life is being stretched thin by the blade, and it causes him an immense amount of pain. Gen decides the pain isn't worth it and swears off ever wanting to be immortal again.]]

* In JohnCWright's ''Golden Age'' trilogy, nomenual recordings allow effective immortality. Although it is a major plot point that the heat death of the universe will ensure that this is not actually living ''forever'' -- the most that is possible is until every form of energy in the universe is completely consumed.

* ''Space 1999'' episode "The Exiles". Two prisoners have extended lifespans due to skintight membranes covering their bodies. If the membrane is ripped and their bodies are exposed, they're subjected to RapidAging and die.

* From the WebOriginal/SCPFoundation, there's [[http://scp-wiki.wikidot.com/scp-963 SCP-963]], a talisman which, if you are killed while holding it, is imprinted with your soul. From then on, anyone else who touches the talisman has their personality overwritten with whoever is contained inside. It's actually possible to make multiple copies of yourself this way.

* The Grand Panacea from ''{{Baccano}}'' has this effect; anyone who drinks it ceases aging and [[GoodThingYouCanHeal almost immediately]] recovers from any injury (seriously, if they're burned the ash turns right back into flesh). The only way to "kill" an immortal is for another to [[IdentityAbsorption absorb]] them (which gives them their memories in the process). There's also lesser versions of it that grant invulnerability and the weakness to being absorbed but not immunity to aging.

* In ''{{Mistborn}}'', [[GodEmperor the Lord Ruler's]] bracers serve this function, though he made them himself. By exploiting a loophole in the magic system, he was able to store his youth and vitality in them and increase its output exponentially- so long as he's wearing the bracers, he's as young as he wants to be, with [[TheAgeless everything that implies]]. [[spoiler:When the heroine rips the bracers off him during their duel, he instantly reverts to his real age- of over one thousand. ''Ouch''.]]

Through magic or science, a character manages to create a device that grants {{immortality}}. How the device works can be very varied -- it may be PoweredByAForsakenChild, thus invoking ImmortalityImmorality, or it could be powered by harmless TechnoBabble. The extent to which it works and what kind of immortality it bestows also varies. It might only work on the user/wearer, or it could work on anyone in the vicinity. It may also have bad side effects, especially if it's a prototype or created by a MadScientist.

Likely to be a MacGuffin or PlotCoupon. SoulJar is a subtrope. If the ImmortalityInducer can be mass-produced, it may lead to a SocietyOfImmortals. Contrast ArtifactOfDeath.

** [[MindScrew Go ahead try and make sense out of that. I dare you]].

* Time spores, a.k.a. "Fruits of Time", in ''{{Mnemosyne}}''.

[[AC:Card Games]]
* The CCG ''Illuminati'' had the card [[http://media.adamdodson.org/index.php/Illuminati-Card-Game/immortality-serum Immortality Serum]], which not only made the affected character indestructible, it could be played on an opponent's characters to make them defect!
* ''MagicTheGathering'' has [[http://mtg.wikia.com/wiki/Fountain_of_Youth The Fountain of Youth]], which gives players a cheap method of increasing their life points. Only the pigeons ever discovered its secrets, since no one in their right mind would drink from a dirty public fountain (especially if pigeons bathe in it).

[[AC:Literature]]

* In ''{{Gor}}'', humans have type II immortality thanks to "stabilization serums" - shots - developed by the Caste of Physicians; basically, it's an immunization against old age. In one book, a woman from Earth actually gets de-aged from her 60s to age 18 or so thanks to the serum. The priest-kings, alien gods of the planet, have even more advanced stabilization serums which make them immortal until they decide to die, although they can be killed.

* {{Bleach}}: the Hogyoku was originally created to eliminate the barrier between shinigami and hollow. Later, it is revealed to grant the heart's truest desires; assuming the Hogyoku is exposed to twice captain level reiatsu, and that one has the inherent potential to fulfill their wish. And then...? [[spoiler: Aizen merged with it and was somehow granted immortality. So... either he was immortal to begin with, or had the potential to become...?]]

* The CCG ''Illuminati'' had the card [[http://media.adamdodson.org/index.php/Illuminati-Card-Game/immortality-serum Immortality Serum]], which not only made the affected character indestructible, it could be played on an opponent's characters to make them defect!

* The Lazarus Pits used by ''Batman'' archfoe Ra's Al Ghul and others can rejuvenate the dying. Ra's Al Ghul is hundreds of years old thanks to the Pits.

* In ''ZombiePowder'', various "powder hunters" search for the rings of the dead, which when brought together produce a substance that can either raise the dead or grant immortality on the living.

* The ''{{Touhou}}'' series has the Hourai Elixir, which was literally created by distilling the concept of eternity into liquid form. It makes whoever drinks it immortal by removing the very concept of death from their being: they will never age, never grow sick, and will instantly heal any injury, no matter how severe. The closest one can get to defeating one is beating them down until the pain makes them not want to fight you anymore. Fortunately, only two people have consumed the Elixer, neither of whom is particularly interested in a fight to the death ([[CycleOfRevenge except between]] [[RevengeBeforeReason each other]]).

* The ''{{Touhou}}'' series has the famous Hourai Elixir, used by Lunarians such as Princess Kaguya and her deadly rival Fujiwara no Mokou.

* The Font of Immortality (the drink, not the typing) is one of the five artifacts in [[Fablehaven]]. The catch is that it must be drank from at least once a week (don't worry, it's infinite), or else the drinker will spontaneously turn to dust.
