Spoilered Rotten!! (We know everybody dies in this one.)
Most characters seen in any sort of media are seen in one swath of their life, usually in a firmly established adulthood. But, rarely, a single character will be depicted in their in-universe media all the way from their infancy to their elderly years, sometimes even all the way from birth unto death. This doesn't even always occur intentionally. Sometimes the initial work depicting a character only intends to show them in one present adventure, but the demands for new angles in prequels and sequels end up painting these parts of their lives as well.
As this is a death trope, there are unmarked spoilers below.
- A televised ad for the Xbox from 2002 has a woman in labor push out her baby with such force that the infant goes flying out the window and over the countryside, aging rapidly as he goes. Within thirty seconds, he's at retirement age, at which he plummets to Earth to slam into a cemetery grave. XBox's moral of the ad: Life is short; play more. Viewable on YouTube here.
- Maquia: When the Promised Flower Blooms: Maquia, who is from a Society of Immortals, adopts an ordinary human baby, raises the child into teenhood, meets him again as an adult, and visits him at what is quite possibly his deathbed in the Distant Finale.
- Millennium Actress: The title character's life story is depicted by way of her film career. It also plays with the concept as the settings of her films span from medieval Japan to science fiction.
- All-Star Superman begins with a brief summary of Superman's birth and childhood before jumping into the main story: how Superman spent the last days before his death.
- Empath from Empath: The Luckiest Smurf. His infancy starts in the novel, though told in a flashback story. And in a flash-forward story "Days Of Future Smurfed", Empath as a very old Smurf spends his last hours telling his great-grandson what he must do.
- Benjamin Button, in The Curious Case of Benjamin Button — almost an inversion, as this could be called Gradle-to-the-Crave, Button starts being born as an "elderly" baby and ages backwards for some 80 years, until he dies looking like an infant.
- Michael Corleone: In The Godfather series, Michael is shown as an infant in the early flashback sequences of The Godfather Part II, and in old age and death in The Godfather Part III. His brother Fredo Corleone is similarly shown as an infant — but doesn't exactly live to die of old age.
- James T. Kirk: although not all appearing in the same time stream, we see Kirk born at the beginning of Star Trek (2009), revisit him at various points in his youth and throughout most of his adult life, and then see him die (in action, but elderly in years) at the end of Star Trek: Generations.
- Luke Skywalker: over the course of the Star Wars Saga, we see (though not told in chronological order) Luke Skywalker being born near the end of Revenge of the Sith, and revisited in the rest of the films until we see his death at the end of The Last Jedi. His twin sister Princess Leia is close to being another character in this category, being shown from birth to old age (and having outlived the actress who played the character). As of The Rise of Skywalker, Leia's death — in a similar fashion to her twin brother, nonetheless — has made her another example of this trope.
- Marley, the dog in Marley & Me, is introduced as a puppy, and is shown over the course of his life until he is elderly (for a dog) and must be put to sleep.
- In the Marvel Cinematic Universe, we see Loki as a baby being adopted by Odin (in a flashback), and we see him die (after a few earlier fake-outs) in Avengers: Infinity War (although a copy of him from another timeline escapes to unknown whereabouts in Avengers: Endgame); though he never appeared elderly, he was hundreds of years old at that point.
- Mr. Nobody follows Neo Nobody from the birth to the end of his life. Several times, since it is a Multiple-Choice Future.
- Predestination begins when the main character is an adult and then follows that character through flashbacks and Time Travel to their birth and to when they're killed by the Bartender.
- In-universe, this is what the titular program from The Truman Show was intended to be for its unwitting protagonist Truman.
Network Executive: For God's sake, Chris! The whole world is watching. We can't let him die in front of a live audience!
Christof: He was BORN in front of a live audience.
- At Her Majesty's Request is about the short, but very eventful life of Sarah Forbes Bonetta, from when she was saved from execution by King Gezo at the age of five and raised by Queen Victoria, to her death from tuberculosis on 15 August 1880.
- The Bible:
- The Book of Genesis follows a bloodline from father to son from the beginning of humanity to Israel's arrival in Egypt, meaning the reader is privy to birth, death, and everything in-between for characters including Noah, Abraham, Isaac, Jacob, and finally Joseph, whose death closes the book in its fiftieth chapter.
- Moses' conception, birth, and adulthood are described in the second chapter of the Book of Exodus before he's tasked with leading the Hebrews out of Egypt at age eighty. The books of Leviticus and Numbers detail the forty years he spends leading Israel while Deuteronomy records the final speech before Moses dies in the book's 34th chapter.
- Books of Samuel begin with Hannah praying to bear a son, a prayer that is answered as the prophet Samuel is conceived and born to her. The first book then follows Samuel's tutelage under Eli, his reign as a Judge, and his relationship with the first kings of Israel. As David starts to step up as a hero, Samuel dies of old age, only to reappear from beyond the grave thanks to the intercession of a medium.
- The Gospels according to Matthew and Luke begin with the conception of Jesus by the Holy Spirit, continue to his birth in Bethlehem, describe his ministry in detail, describe his death on a cross, and end by going past the grave to describe his Resurrection from the dead. But the character is generally not depicted as achieving old age and a natural death, except in certain apocryphal writings.
- A Dog's Purpose stars a dog from birth to death... then birth and death again... and again... He goes through several reincarnations over the book and its sequel.
- Emperor Claudius, title character of I, Claudius and Claudius the God; the novels' premise is that the two books were an English translation of Claudius' long-lost autobiography, with the early chapters covering the events before his birth and the last chapter being finished shortly before his death. The second book has an epilogue discussing the circumstances of his death and the subsequent reign of Emperor Nero.
- The picture book Island Boy by Barbara Cooney follows the title character Matthias from his early childhood, through his adulthood and the births of his children and grandchildren, to his death in a boating accident as an old man.
- Leopold von Sacher-Masoch's 1878 novel The New Job tells the life story of an eastern Galician peasant from birth through old age. Some reviewers at the time were under the impression it was a biography rather than a novel.
- This happens with a lot of characters in Warrior Cats, due to the long timespan of the series; the most notable examples are Tallstar, Bluestar, Crookedstar, and Yellowfang, who have super editions that feature them born as a kit (an infant) while they die in the main books, with Bluestar and Tallstar having their death included in the super edition itself.
- The first Wicked book begins just before Elphaba's birth and ends just after her Foregone Conclusion Accidental Murder by Dorothy.

- In Roots, we meet Kunta Kinte soon after he's born, in the village of Juffre, Gambia, in the middle of the 18th century. In his late teens, we see him getting captured and sold to slave traders that transport him across the Atlantic Ocean from Africa, and is then auctioned off to John Reynolds, who intends to put him to work in his tobacco plantation. After being forced to acknowledge his name is now "Toby", and after several failed escape attempts, Kunta realizes he'll never go home and that he'll be a slave for the rest of his life. After being sold to Reynolds' brother William, he marries a female slave named Bell, and they have a daughter named Kizzy, who in her a teenage years brings the wrath of their owner. A middle-aged Kunta and Bell helplessly see her sold off to another plantation. Years later, while being courted by a slave named Sam Bennett, Kizzy goes back to the Reynolds' plantation, where she learns her mother was sold off to another plantation, and her father was buried under a wooden grave marker. She uses a rock to scratch out "Toby" and write "Kunta Kinte" underneath, before returning to her own plantation.
- In the Roots remake, after Kunta accepts the grim reality he'll live the rest of his life as a slave, he marries a slave woman named Belle, and they have a daughter named Kizzy. After Kizzy learns to read and write, she forges some "freedom papers" for another slave, which results in his death when fugitive slave hunters try to recapture him. Enraged at this development, her master sells her to another plantation as Kunta and Belle cry out for her. On the night of her arrival, she's raped by her new master, which results in the birth of her son "Chicken" George Lea. They stay together for several decades in the same plantation, even when a freedman tried to court her, and even after George got married and started a family of his own. Kizzy and George part ways when his master/father loses him on a high stakes cock fight, and George is taken against his will to England. When his English master frees him twenty years later, George goes back to the Lea plantation, where he discovers that Kizzy, his mother, died years before, and after paying his respects to her grave, he goes to confront his former master.
