* We know in the Golden Age saga of ''Manga/{{Berserk}}'' that Guts, who starts off as a loyal mercenary soldier under Griffith, will eventually be betrayed by Griffith and gain the Mark of Sacrifice, leading him to become the merciless Black Swordsman. What that means, unfortunately, is that pretty much everyone else in the Band of the Hawk aside from Guts and Griffith is doomed to a bad fate. But what we ''don't'' know is that [[spoiler:while nearly all of the Hawks are branded like Guts and indeed die horribly when the Eclipse goes down and the demons come out of the woodwork for the feast, there are two other Hawks who ultimately survive -- Rickert, due to not being with the rest of the Hawks when the Eclipse went down; and Casca, who, despite being branded like the rest and being put through pure hell by Griffith himself upon him becoming a demon god, was rescued along with Guts by the Skull Knight, but who went insane from her ordeal and was left behind with Rickert and the blacksmith Godot, and ultimately becomes the reason for Guts to lay aside his vendetta against Griffith for her sake]].

** In the Order 66 arc, the audience knows Fives won't be able to reveal the truth behind Order 66, because it remains unknown in ''Film/RevengeOfTheSith''. Most of the tension comes from the fact that even though he can't succeed in his quest, there's still hope he'll at least ''survive''.

* ''ComicBook/StarWarsKanan'': Depa Billaba is known to have been killed by her clone battalion when Order 66 was issued, so not only are the friendships developed between them and Kanan doomed their betrayl and murder of their general is shown in the second issue before they are developed further.

*** It's also mentioned that George and Mary's marriage was in such turmoil before this that George had an affair. Their marriage on the show is no where near as bad as ''The Big Bang Theory'' claims. [[spoiler:George and Mary begin fighting a lot more often as the series progresses, and after a particularly nasty fight in the season 4 finale, George runs into recently-divorced neighbor Brenda Sparks at a bar, implying that she is the other woman.]]

** Uncle Ben is the poster boy of "DeathByOriginStory". His death, an unexpected consequence of Peter being selfish and using his powers for personal gain, made him learn that "WithGreatPowerComesGreatResponsibility". That means that any adaptation of Spider-Man where Ben appears from the start (such as ''ComicBook/UltimateSpiderMan'' or [[Film/SpiderMan1 the first Sam Raimi's film]]) will have him die very soon.

* ''Manga/RainsHead'': Rain, as it turns out, is inflicted with a terminal illness that gives her three years to live. [[ForegoneConclusion It's no spoiler already to anyone who reads just the manga's first chapter when Claroa makes it very clear to her that she will not survive from it.]]

* In ''WesternAnimation/TheLittleMermaid1992'' and ''WesternAnimation/TheLittleMermaidIIIArielsBeginning'', Ariel has to be unaware of Eric's existence. Conversely, ''Ariel's Beginning'' is the earliest-set installment of the franchise - and the only one to feature Ariel's mother. Mom's totally doomed, isn't she? [[MissingMom Yes, she is.]] Also, Marina's goal in ''Ariel's Beginning'' is to steal Sebastian's job as King Triton's advisor. Sebastian is seen holding the job in the other installments.

* ''Roleplay/InkCity'' saw an unusual case of this when Thrasher became aware of his status as a character from the show ''WesternAnimation/{{Robotomy}}''. Specifically, he learned that it got ScrewedByTheNetwork, and due to this, his universe was completely destroyed when the creators disposed of all their show-related materials. [[GoMadFromTheRevelation He took that about as well as you'd expect]].

* ''Fanfic/AgeOfCalamity'' is a direct prequel to ''Fanfic/BreathOfTheWild'' in ''Fanfic/TheMythOfLinkAndZeldaSurvivorsofTheCalamity'', taking place during the buildup to the awakening of Calamity Ganon. Naturally, this means Ganon wins, the Champions die, and Link is placed into Stasis while Zelda ends up in a duel with Ganon.

* A saying in the Hong Kong comic ''The Manhua/RavagesOfTime'' goes, "Those who are fated to die, will die. Those who are fated to live, will live." That is to say, every character is going to die at the time that they did in [[Literature/RomanceOfTheThreeKingdoms the source material]], even if the circumstances vary quite widely, while at least two original characters were created/centered around specific story arcs and thus were doomed to go when that arc was up[[note]]Yuan Fang would not survive the Battle of Guandu, since he was created to make it more cooler/complex than the version in ''Romance of the Three Kingdoms'', while Xiao Meng--who debuted as the real identity of the fictional Diaochan--would not survive the final downfall of Lu Bu[[/note]].

* ''Anime/Danganronpa3TheEndOfHopesPeakHighSchool'': As the Despair Arc is a prequel to the rest of the series, we already know who's going to die and who's going to [[spoiler:become Remnants of Despair]]. It just serves to fill us in on all the details. Exaggerated with the fate of [[spoiler:Yukizome]], who was just killed off at the end of the first episode of the Future Arc and whom posthumously comments on their doomed status in the intro to the Despair Arc.

* ''Manga/OnePiece'': An extended flashback showing how Wano became the hellhole it is now and Kozuki Oden's story has the villainous Orochi being assisted by two Devil Fruit users. An old woman with the Clone-Clone Fruit and an old man with the Barrier-Barrier Fruit. Since only one person may have a Devil Fruit power at any time, and we've seen that in the present day different people have those specific powers, it's immediately clear they're both dead by now. Indeed, the old woman is killed offscreen by Kaido for interfering with his battle with Oden (although she probably saved Kaido's life, the one thing he hates the most is for the chance to have an evenly matched fight with a WorthyOpponent snatched from him, since he's so strong, few can stand up against him in battle).

* ''Fanfic/TheNutdealerExpandedUniverse'' (''VideoGame/{{Deltarune}}'' & ''VideoGame/Undertale}}''): "Nut Leader" opens with a council of sapient nuts plotting Nathan's downfall. Since "[=TunaElder=]" had already shown his arrest for public exposure ruining his reputation, it was only a matter of how.

* ''Webcomic/ALittleHintOfBlue'' shows Skara dating Fled ([[NamedByTheAdaptation the boy who asked her out to Grom]]) during the timeline of [[WesternAnimation/TheOwlHouse the original show]], but [[Webcomic/MoringMarkTOHComics other comics by the author]] that came out beforehand establish that she eventually goes on to marry Viney instead, so no matter what her and Fled aren't going to stay together in the long term.

* ''Webcomic/ALittleHintOfBlue'' shows Skara dating Fled ([[NamedByTheAdaption the boy who asked her out to Grom]]) during the timeline of [[WesternAnimation/TheOwlHouse the original show]], but [[Webcomic/MoringMarkTOHComics other comics by the author]] that came out beforehand establish that she eventually goes on to marry Viney instead, so no matter what her and Fled aren't going to stay together in the long term.

* The "A Little Hint of Blue" storyline of ''Webcomic/MoringMarkTOHComics'' shows Skara dating Fled ([[NamedByTheAdaption the boy who asked her out to Grom]]) during the timeline of [[WesternAnimation/TheOwlHouse the original show]], but comics that came out beforehand establish that she eventually goes on to marry Viney instead, so no matter what her and Fled aren't going to stay together in the long term.
