The Grim Reaper is always considered to be the embodiment of death. As such, it only makes sense that such a being would be considered immortal and unable to actually die. Can't die if you are death itself.
Not so much the case here. If this trope is in play, then death is just as capable of dying as everybody else. In some cases, the grim reaper getting killed off ends up coming with some serious consequences. In other cases, death is simply reborn and continues his business. If somebody is responsible for the reaper dying, they might be forced into taking up the role.
Spoilers will not be marked due to this being a Death Trope.
- Secret Wars II: The Beyonder is a Reality Warper who wants to make things better for mankind, and doesn't think that mere superhero stuff is enough. An advisor convinces him to kill Death itself, but unlike most of his other feats, this one would not be possible to reverse. After he does this, cosmic entities show up and complain that The Beyonder has upset the cosmic balance. The Molecule Man argues that, without death, life is meaningless. The advisor agrees. They've made a terrible mistake. But, as resurrecting (the original) Death is beyond the Beyonder's power, he instead turns the advisor into a new personification of Death.
- Nekron, the Embodiment of Death in The DCU is the Big Bad of the Zombie Apocalypse Crisis Crossover event Blackest Night. Being Death himself, it's impossible to kill him, even with Sinestro taking The Entity and converting himself into a White Lantern. But he was eventually defeated when Hal Jordan and the rest of the superheroes that had been revived, included The DC Trinity take The Entity's power and all become White Lanterns and all of them aim at Black Hand (Nekron's avatar and connection to the Earth) with their rings and revive him as a White Lantern too, causing Nekron to explode.◊ He is later resurrected as part of a Godzilla Threshold to kill The First Lantern Volthoom, but is imprisoned a second time for good.
- In The Thanos Imperative, we see an alternate universe called "The Cancerverse". In the Cancerverse, life won and Death was destroyed. This resulted in all life in the universe becoming a Cosmic Horror Story (almost all living beings in the Cancerverse worship the "Many Angled Ones") and almost all available space in the universe is filled by a truly horrifying organism, described as "a cancer attempting to metastasize into our reality" to find more space to occupy.
- In the second arc of Jane Foster: Valkyrie, Valkyrie has to team up with other medically-themed heroes to treat Death for a mysterious illness. Death is ailing because the Marvel universe has even more resurrections than usual in 2019-2020. Gamma mutates are all allowed to resurrect now (Immortal Hulk), and mutants also have a "get out of death free" card thanks to the Resurrection Protocols in Dawn of X. And while curing Death, Valkyrie justifies it by deducing that the death of Death would lead to "a sort of Cancerverse" — see the note on The Thanos Imperative above.
- In the first issue of The Sandman a magician attempts to summon and bind Death, only to get Dream instead. When he finally escapes over 70 years later he tells the magician's son that it was very fortunate for the planet that they snared Death's little brother instead of her.
- This is the premise of the French comic Zorn et Dirna: a king has managed to imprison Death through a magical ritual. As a result, nobody dies, even those for whom it would be a blessing, and killing someone means that their ghost will enter the killer's body as an additional personality. The titular characters are two siblings who can cause someone to actually die when they both touch them.
- In George A. Romero's Living Dead Series, zombification is not spread through The Virus as it is in many later zombie stories; rather, everybody who dies from any cause that does not destroy the brain comes back as a zombie. Multiple explanations are given by various characters throughout the films, but the most famous one comes from Peter in Dawn of the Dead (1978), who tells a story his Macumba priest grandfather told him about how, when there's no more room in Hell, the dead will walk the Earth. (Peter's actor Ken Foree repeats this line in the remake during his cameo as a fire-and-brimstone televangelist, in this version suggesting that the undead are The Scourge of God.) In Diary of the Dead, the in-universe documentary that the characters make about the Zombie Apocalypse is even titled The Death of Death.
- Incarnations of Immortality: Anthropomorphic Personifications like Death are revealed to be "Offices" that are filled by specific mortals. In On a Pale Horse, a suicidal man is so startled to see Death come for him that he puts a bullet through the Grim Reaper's head, only to learn that You Kill It, You Bought It. It's mentioned that Death's armor is completely invulnerable, but sooner or later everyone gets careless or bored enough to let themselves be killed.
- Reaper Man opens with Death being fired and given a mortal life by the Auditors of Reality. At the climax of the book, the new Death comes to claim him and the old Death outsmarts and kills his would-be replacement. And the reason that Death was "retired"? The Auditors thought he cared about his "charges" too much. The New Death...didn't.
- Played with in the Grand Finale of The Colbert Report. In the intro to the "Cheating Death with Dr. Stephen T. Colbert, D.F.A." segment, Grimmy finally catches Stephen cheating at their chess game and tries to kill him, only for Stephen to pull a gun and kill Grimmy instead. Stephen then absorbs Grimmy's power Highlander-style and becomes immortal.
- Played with in the Red Dwarf episode "Only the Good ". Rimmer is left to die on a rapidly disintegrating Red Dwarf. Death comes to claim him and Rimmer kicks him in the testicles. Rimmer says that "Only the good die young" and runs off, leaving Death to note that this has never happened before and collapse in pain.
- In Supernatural, Death himself met his demise at Dean's hands after handing him the only thing in existence that could kill him, his scythe. To elaborate, Dean was being corrupted by the Mark of Cain into becoming a bloodthirsty killing machine, couldn't be killed since the Mark would simply resurrect him, and couldn't have the Mark removed because it was the seal to an even more dangerous Sealed Evil in a Can. Death offered to lock him in a Prison Dimension where he wouldn't be able to hurt anyone else, on the condition that he kill Sam, because he knew that as long as Sam was alive, he would tirelessly search for a way to get Dean back and eventually succeed, which would ruin the whole point of locking him away in the first place. Death handed Dean his scythe so he could do the deed, only to get a face full of it himself. Of course, since Death had plenty of Reapers working under him, his death didn't affect actual death that much, and one of them is eventually promoted to the new Death.
- In the final season, Billie, the aforementioned new Death, is killed by the Shadow/Cosmic Entity. And her successor is easily killed by Lucifer. In both these cases, they have to be killed as Reapers before they become the new Death, so both Billie and her successor die twice.
- The premise of Torchwood: Miracle Day is that one day everybody suddenly stopped dying. It turns out to be something to do with the immortal Jack Harkness's blood, and Torchwood successfully reverses it.
- In both scripture and church tradition, Christ is said to have conquered death with his resurrection.
The last enemy to be destroyed is death - 1st Epistle to the Corinthians 15:26
Then Death and Hades were thrown into the lake of fire. This is the second death. -Revelation 20:14
- At the end of The Bible, Death itself will be destroyed.
- In AdventureQuest Worlds, during the "AQW Zombies" Saga, Sepulchure pulls off one of the most impressive Did You Just Punch Out Cthulhu? examples ever. Sepulchure starts off by killing King Alteon, and since this was someone of importance Death arrived personally to guide his soul to the afterlife. Sepulchure then confronts Death who taunts him that he would reap Sepulchure's soul one day too, only for the DoomKnight to defiantly tell Death this would not happen. Death laughs and mockingly asks Sepulchure if he was going to "kill Death", to which he replies with a Flat "Yes" and slays the Grim Reaper then and there.
Player Character: Did Sepulchure just kill Death?

However, people can still die by means outside aging, like sickness or being attacked by a monster.
- Dragon's Crown subverts this with the boss of The Castle of the Dead's B route. The Wraith is normally immune to damage unless a Goddess Statue is lit. While you can fight back, the narrator will state that you can't destroy death, the opposite of life. The most you can do is either flee the stage or destroy its dream heart to send it back to the underworld.
