Living on Borrowed Time

Characters who are technically "already dead" but, by one way or another, are able to put it off. Maybe they grafted machine parts onto themselves to support their new way of life. Maybe they just have to avert their death constantly because You Can't Fight Fate.

The long-term version of The Last Dance. If they're so heavily consumed by their Life Support that they're practically alive In Name Only, it's And I Must Scream. If they apply it after they die, they're The Undead (Revenant).

Anime and Manga

 * of XXX Holic technically died several hundred years ago, but a reality warp put that on "hold" for a while.

Realizing fate had given them a reprieve, they become adventurers, in order to make the most of their "borrowed time". They don't fear death since they have already "died."
 * The origin of Iron Man. He has a nuclear reactor his chest that powers a magnet that keeps shrapnel from entering his heart and killing him. In Real Life, he'd be dead.

 * The Final Destination films run on this; all the protagonists have somehow cheated death, and Fate is trying to redress the balance.
 * The Replicants in Blade Runner have a four year lifespan. In both the movie and the tie-in game the antagonist Replicants attack their creator so that he will extend their lifespans. Sadly, according to their creator the limited lifespan is not a design choice -- it is impossible to give the Replicants more time than that. Time that they have wasted on violence and revenge.

Live-Action TV

 * After Desmond prevents 's death in Lost, he becomes perpetually suspended in Death because You Can't Fight Fate.
 * The New Avengers had an episode about an enemy agent who had a bullet working its way toward his brain, and was desperate to kill Steed before that happened.
 * Burai of Kyoryu Sentai Zyuranger. His days were numbered- literally. He already died once before the events of the series when his sleep chamber collapsed while he was still inside during his suspended animation, but Clotho, the Spirit of Life, revived him to assist the Zyurangers, but only for a limited period. Burai's remaining time was represented by a flickering green candle that would gradually melt down with each passing hour and the only way Burai could preserve his limited lifespan was by staying inside a "lapseless room". Because of this, Burai would only get out of his room to assist the Zyurangers whenever they seriously needed him. The longer Burai would stay outside his room, the less time he had left to live.
 * When he came back, Tommy, the American equivalent, knew he had only a few morphs before he would lose his powers. Power Rangers Lightspeed Rescue gave us another Sixth Ranger who was actually Living On Borrowed Time, cursed with a snake marking that would move higher on his body with each morph. If it reaches his neck, it's adios. Of course, given the nature of the trope...
 * In Babylon 5, captain John Sheridan was killed but later revived with an infusion of life energy. He is later told that he only has a maximum of twenty years left before this energy burns out.

Tabletop Games
"A life cut short. A quest left unfinished. One more task to be done."
 * In Warhammer 40000, The Emperor of Mankind was mortally wounded by his son/clone Horus (whom he killed just moments later; yeah, it was one Big Screwed Up Family), then strapped onto a life-support system called Golden Throne, from which he psychically directs Terran spaceships. Other than that... see for yourself.
 * Also, from the same setting, the Ultramarine Primarch Roboute Guilliman, who was also stabbed in the throat with a poisoned sword and frozen in permanent stasis field just moments before death. An Urban Legend says that he is regenerating despite it being physically impossible in the stasis.
 * In the game itself, there's the Black Templars Chaplain Grimaldus - who has a special rule called Only in Death does Duty End, permitting him to ignore fatal wounds as long as he continues to hold his nerve and focus on the Emperor's Will, although it's specified that even if this lets him finish out the battle, he's considered to die at the end.
 * In the 3.5 Dungeons and Dragons supplement The Book of Erotic Fantasy (a 3rd-party supplement dealing expressly with sex and all its aspects in the terms of the d20 system), there is a spell called Shadow Life. It is distinctly separate from the theme of the rest of the book, as on its own it has no sexual connotations. It grants the target ( a recently-dead character) one extra day of life for every level the caster has. The flavor text is especially poignant.


 * Can count as Miles to Go Before I Sleep, and is thus on that page too.
 * In 3.5 proper, The Book of Exalted Deeds gives us the Risen Martyr Prestige Class. Someone who has died in the name of a good cause is brought back and granted special powers to fulfill that cause. When the work is finished or they have reached eleven levels after the point of resurrection (whichever comes first), the Risen Martyr is taken bodily into the Higher Planes and granted whatever reward is waiting for them.
 * Magic the Gathering, always eager to have every applicable trope, gives us fading and vanishing. A character with fading X has X fade counters, and each of its controller's turns, that player removes one fade counter or sacrifices it. Vanishing is the same, only once the last time counter is removed, the card is sacrificed. Uses for this vary from "make a creature cheaper" to actually tying removing counters to its ability.
 * In Ravenloft, Gennifer Weathermay-Foxgrove is given a pocket watch literally named Borrowed Time by a Vistani, which she later returns. The watch's powers are somewhat vague in the narrative, but it's implied that using it will save the user's life at the expense of making her death inevitable at some point in the indeterminate future.

Eventually, the taint drives them mad with neverending prophetic dreams of Darkspawn as the taint takes over their minds. At that point, Senior Wardens retreat to the Deep Roads and choose to go out in a blaze of glory against the Darkspawn.
 * The Awakening expansion reveals that mages are immune to this particular side-effect of the taint, because their awakened connection to the Fade. Mind you, they still have all the other bad side-effects of both Wardens and Mages, which makes the extended lifespan something of a double-edged sword.
 * In Fate Stay Night, this happens to in the normal end of the Heaven's Feel route. Running only on pure determination to stop, he manages to , even after his mind has long been destroyed and his body is constantly being destroyed by blades.
 * This happens to in Crysis 2.
