Immortality is a popular subject in fiction, as it explores humanity's deep-seated fears and comprehension of its own mortality. Immortal beings and species abound in fiction, especially fantasy fiction, and the meaning of "immortal" tends to vary.
Some fictional beings are completely immortal (or very nearly so) in that they are immune to death by injury, disease and age. Sometimes such powerful immortals can only be killed by each other, as is the case with the Q from the Star Trek series. Even if something can't be killed, a common plot device involves putting an immortal being into a slumber or limbo, as is done with Morgoth in J. R. R. Tolkien's The Silmarillion and the Dreaming God of Pathways Into Darkness. Storytellers often make it a point to give weaknesses to even the most indestructible of beings. For instance, Superman is supposed to be invulnerable, yet his enemies were able to exploit his now-infamous weakness: Kryptonite. (See also Achilles' heel.)
Many fictional species are said to be immortal if they cannot die of old age, even though they can be killed through other means, such as injury. Modern fantasy elves often exhibit this form of immortality. Other creatures, such as vampires and the immortals in the film Highlander, can only die from beheading. The classic and stereotypical vampire is typically slain by one of several very specific means, including a silver bullet (or piercing with other silver weapons), a stake through the heart (perhaps made of consecrated wood), or by exposing them to sunlight.
Mythological beings are often used in modern fiction as characters, as a plot device, or even just as "window dressing". Such beings are often either immortal or associated with immortality.
Tezuka Osamu's lifework Phoenix (known in Japan as Hi no Tori) had a phoenix whose blood would provide immortality. In various ages, many "heroes" and "heroines" would strive for immortality only to realize that there is something beyond eternal life. In one story titled "Rose Ham" (lit. "Next World Story") the last remaining human male who survived a holocaust, blessed (or cursed) with immortality through the phoenix blood, would create another beginning of life. In his immortal form, he would see a race of slugs, after gaining intelligence, destroy themselves in another holocaust. He would seed the earth with life that would become present day humans, and finally leave the earth to join his lover, who died billions of years ago, in heaven.
In the Cthulhu Mythos created by H. P. Lovecraft, there is a race of "Fish-Men" known as Deep Ones. They stop aging after reaching adulthood and can breed with humans to birth offspring with this "eternal youth." This is a faustian bargain, as after reaching the age of 20, the Deep One Hybrids undergo a transformation from normal humans into Deep Ones. They also lose all concept of humanity and morality and go to live in the ocean with the Deep Ones and to worship the undersea deity Father Dagon, the Ruler of the Deep Ones and consort to Mother Hydra.
Since immortality is seen as a desire of humanity, themes involving immortality often explore the disadvantages as well as the advantages of such a trait. Sometimes immortality is used as a punishment, or a curse that might be intended to teach a lesson. It is not uncommon to find immortal characters yearning for death. In Greek mythology Tithonus was given immortality by Zeus at the behest of his lover Eos, but she did not ask for eternal youth as well so he grew older and weaker and was turned into a cicada, eternally begging for death.
In some parts of popular culture, immortality is not all that it is made out to be, possibly causing insanity and/or significant emotional pain. Much of the time, these things only happen to mortals who gain immortality. Beings born with immortality (such as deities, demigods and races with "limited immortality") are usually quite adjusted to their long lives, though some may feel sorrow at the passing of mortal friends, but they still continue on. Some immortals may also watch over mortal relations (either related to or descended from them), occasionally offering help when needed.
In legend, most famously in Wagner's opera The Flying Dutchman, a ship's captain is cursed with immortality after attempting to sail around the Cape of Good Hope in a terrible storm. He is doomed to sail around the Cape forever.
In Jonathan Swift's Gulliver's Travels, some of the inhabitants of the island of Immortals (near Japan) don't die, but they age and become ill, demented, and a nuisance to themselves and those surrounding them. Swift presents immortality as a curse rather than a blessing.
In Mary Shelley's short story "The Mortal Immortal", the protagonist of which witnesses everyone he cares about dying around him.
In Mikhail Lermontov's 1841 poem Demon, the protagonist is burdened by his immortality. Outcast from Paradise, "his desert had no refuge in it: and one by one the ages passed, as minute follows after minute, each one monotonously dull." He seeks escape in love, but fails.
In his story "The Immortal", Jorge Luis Borges explored the idea that life gets its meaning from death; an entire society having achieved immortality, they found time becoming infinite, and so found no motivation for any action. The central character begins by seeking the water of eternal life and then spends centuries seeking the water of death.
In Gerald Kershs "Whatever Happened to Corporal Cuckoo?" the eponymous corporal was given immortality by Ambroise Paré's digestif in 1537. He has been trying to replicate the exact recipe he received ever since and has never done so. Corporal Cuckoo was not only made immortal. He retained the same personality and defects he had in 1537: it has taken him four hundred years to reach the rank of corporal. Because he has learned no more and has not become wiser, however, the corporal does not suffer the misery of other fictional immortals.
In his book Thursday's Fictions, and the stage and film adaptations of it, Richard James Allen tells the story of a woman named Thursday who tries to cheat the cycle of reincarnation to get a form of eternal life. At the end of this fantastical tale, her son, Wednesday, who has witnessed the havoc his mother's quest has caused, forgoes the opportunity for immortality when it is offered to him. Likewise, the novel Tuck Everlasting depicts immortality as "falling off the wheel of life" and is viewed as a curse as opposed to a blessing.
In Anne Rice's book series The Vampire Chronicles, vampires are portrayed as immortal and ageless, but their inability to cope with the changes in the world around them means that few vampires live for much more than a century, and those who do often view their changeless form as a curse.
Zardoz, a 1974 movie by John Boorman, features Eternals and Brutals, with the former having listless lives.
In The X-Files episode "Tithonus" (titled after the Greek mythical figure, above) Agent Scully meets an unhappy immortal man who is over two centuries old, after he had accidentally cheated death. He is miserable and longs for death. She queries him about why, arguing immortality is a great blessing. However, he replies that 70 years is all anyone really needs-after that it simply becomes unbearable. Elaborating, he tells her that after a time the details of his early life faded from his memory. As a result, he can no longer even remember his deceased wife's name. Further, being immortal has left him totally alone, since no one else has the same condition. He can also be wounded, though his injuries fade, and thus suffers yet still lives on.
In general, a theme seen with many variations, is the notion of an essential world weariness akin to extreme exhaustion for which death is the only relief. This is inescapable when immortality is defined as (half) infinite life. Immortality defined as finite but arbitrarily long per the desire to exist does not, as a definition, suffer this limitation. When a person is tired of life, even death is shut off to them, creating an endless torture.
The 2018 science fiction TV series Ad Vitam explored the social impact of biological immortality.
The undead are fictional people who have died and still maintain some aspects of life. In many examples, the undead are immune to aging or even heal at an accelerated rate. Dracula is one of the most famous examples of the undead.
Immortality can be achieved in fiction through scientifically plausible means. Extraterrestrial life might be immortal or it might be able to give immortality to humans. Immortality is also achieved in many examples by replacing the mortal human body by machines.
A modern day example of Mind-to-computer immortality is displayed in Netflix's show Altered Carbon. In this show, immortality has been achieved through the use of "stacks" (modules that contain the consciousness of a person and is transferable). Altered Carbon displays both the ethics and qualities of enabling such a use of immortality.
There are many examples of immortality in fiction where a character is vulnerable to death and injury in the normal way but possesses an extraordinary capacity for recovery.
The long-running British science-fiction series Doctor Who focuses on a character called the Doctor, a member of the alien Time Lord race, who can "regenerate" instead of dying or aging; however, rather than simply healing wounds, this results in a Time Lord's entire physical appearance changing when fatally wounded or terminally sick. Most Time Lords are only capable of doing so twelve times before finally dying forever, but the Doctor and his friend-turned-foe the Master have each gone beyond this limit, the Master possessing others before the events of the Time War led to him and the Doctor being granted a new cycle of regenerations for helping their people in the conflict.
Wolverine from the Marvel Comics is famously able to heal from any injury, making him functionally immortal. He has sometimes been depicted in the far future having aged little from his "present" appearance.
