-->-- ''Videogame/EternalDarkness'', Introduction (abridged).

Between the [[DeathTropes many ways death can be used in media]], there's its use as [[IncitingIncident a trigger for the start of the story itself]]. It could start a RoaringRampageOfRevenge from part of the protagonists and pull them into something even greater, maybe looking for the truth behind the death could make the protagonist know about [[HeKnowsTooMuch something he wasn't supposed to know]], the protagonist could suddenly see himself [[TakeUpMySword having to continue where the deceased left off]], or the execution of a baddie [[MyDeathIsJustTheBeginning may bring forth something even worse]], etc.

In order for a death to be covered by this trope, it has to satisfy some conditions:

* The death has to either occur [[PosthumousCharacter before the story begins]], or during the first moments of it.
* The death must either:
## Make the plot start moving (without needing to affect the protagonists directly at first), or
## Make the protagonists start taking some kind of action which later pulls them into the big plot (which must not be necessarily related to the death).
* In case of TV series or long runners with clear continuity, the death must have affected the big picture of the series. For example, the deaths occurring on every episode of a murder mystery series do not count; but the death of a close one that made the protagonist take the decision to become a detective so he could investigate the mystery behind that murder ''does'' count. Deaths on this kind of works that trigger new mystery arcs also count.
* On some occasions, the death is ''self''-triggered: if MyDeathIsJustTheBeginning, then the protagonist obviously can't force the antagonist to stop... antagonizing.

Can sometimes overlap with StartsWithASuicide, PosthumousCharacter, DeathByOriginStory, TheLostLenore, ILetGwenStacyDie, StuffedInTheFridge, CrusadingWidower, DoomedHometown (can be a greater scale of this trope), and the list [[LongList goes on and on]].

!!As a death trope, unmarked spoilers are bound to appear. Beware.


[[folder: Anime and Manga ]]
* Episode 1 of ''LightNovel/HighschoolDXD'', shows the main character dying ''before the show even begins''.
* In ''Manga/OnePiece'', the death of Gold Roger launches the Golden Age of Piracy, the setting of the story.
** His FriendlyEnemy Whitebeard similarly launched a new era of piracy with his own death.
** The death of Corazon [[spoiler:(aka Donquixote Rocinante, Donquixote Doflamingo's younger brother and Trafalgar Law's idol)]] is the primary driving force of the Pirate Alliance Saga. [[spoiler:His death earned Doflamingo Law's hatred, causing him to spend the next thirteen years of his life plotting revenge. If Corazon had never died, it's highly doubtful Law would've been a ''pirate'', let alone one of Luffy's allies. Seeing as the Dressrosa arc now involves practically every major power in the world, you could easily argue that his death is an integral part of how the new era of piracy will be shaped -- which is ironic considering that Corazon was a ''Marine spy'' sent to infiltrate his brother's pirate crew.]]
* ''Anime/CodeGeass'': C.C. "dies" but not before granting Lelouch a Geass. With his new superpower, he investigates the murder of his mother Marianne, whose own death initiated plot as it led to Lelouch and Nunnally being exiled to Japan.
* ''Anime/TengenToppaGurrenLagann''; although not at the start of the plot, the death of Kamina (a quarter of the way in) was the key trigger to the character development of Simon throughout the rest of the series
* The first/second season of ''Anime/YuGiOh'' is motivated by the death of Pegasus's wife.
* ''Manga/DeadmanWonderland'' employs this in true gory fashion: an entire classroom of junior high students gets outright blended to bits by the Red Man (A.K.A. "Wretched Egg"), save for Ganta Igarashi- implanted with a Branch of Sin, turned into a Deadman, and tactically framed for the killings so he's sent to the titular hellhole prison.
* ''Manga/FullmetalAlchemist'': The death of Ed's and Al's mother pushes them to perform human transmutation to try to bring her back; their attempt [[GoneHorriblyWrong goes horribly wrong]] and they end up losing (part of) their bodies, thus prompting Ed to join the military to find a way to restore themselves, and the rest is history. Her death is what ultimately caused their involvement in the whole story, and ironically, it's also one of the only two non-[[BigBad Big Bad]]-related deaths in the whole series.
* ''Anime/GaReiZero'': The death of Kagura's mother a few days before the series starts up results in Kagura meeting [[TragicHero Yomi]], and played a significant role in Kagura starting her career as a Vanquisher so early.
* ''Anime/TheSoulTaker''
** Mio's actions just prior to death are what awakened Kyōsuke's mutant powers and his realization that she did so out of love is why he chooses to protect humanity.
** Maya also qualifies. Her death is what inspires Kyōsuke to find and protect the other Flickers, rather than just saving his sister.
* ''Manga/{{Naruto}}'': The title character is the person-shaped can for a monster the city's previous leader (who is also the titular character's father) died sealing in him when he was a baby. Much, much later, we learn that in a technical way, ''[[TheLostLenore Rin's death]]'' of all things is what started the plot. Why? Because her death in the backstory directly motivated [[spoiler:Obito]] into becoming '''''[[TheHeavy Tobi]]'''''...who unleashed the monster on the city in the first place, prompting the leader to seal it away inside the title character.
** It goes much deeper than that -- it's ultimately the reason why [[spoiler:Obito]] took up Madara's offer, leading to the creation of the Akatsuki, the attack of the Nine-Tailed Fox, the Uchiha Clan Massacre, and eventually, the Fourth Great Shinobi War. Had she not died, the entire plot of ''Naruto'' would have been avoided almost entirely, and chances are that both Naruto and Sasuke would have had much happier lives.
** Going back even further, it was the death of [[spoiler:Princess Kaguya]] that laid the foundations for current events due to [[spoiler:Black Zetsu manipulating events in an attempt to revive her]].
** Izuna was his brother Madara's entire world. Madara is the man he is today because of Izuna's death, [[spoiler:which allowed him to be susceptible to Black Zetsu's manipulations.]]
* ''Anime/SerialExperimentsLain'': The [[StartsWithASuicide suicide of Chisa Yomoda]] and subsequent e-mails claiming to be from her are what kick off the story.
* ''Manga/AkameGaKill'': The deaths of Tatsumi's two friends from his village motivates him to join the Assassin Group Night Raid, a group devoted to taking down targets in the EvilEmpire.
* ''Manga/InuYasha'':
** Kikyou's death was the trigger for almost everything that occurs in the story. It's why Inuyasha and Naraku are enemies, it's why Kagome was dragged back in time, it's why the Shikon no Tama is released back into the world and it's why Kagome is the only one who can decide the jewel's ultimate fate.
** Also, the reason Miroku becomes a part of the group in the fight against Naraku is because his grandfather was such a significant enemy of Naraku's that Naraku cursed Miroku's entire lineage: the deaths of Miroku's grandfather and father are the reason he encounters Inuyasha's group and joins it, which is what enables Inuyasha to learn the identity of Kikyou's killer in the first place.
* ''Manga/{{Bleach}}'':
** The deaths of Masaki Kurosaki, Souken Ishida, Kaien Shiba, and Hisana Kuchiki all combine to create the reason for why the first 181 chapters of the manga unfold as they do. Even after those chapters have passed, Masaki's death continues to be the motivation for [[TheHero Ichigo's]] resolve to protect as many people as he can, Souken's death remains the primary motivation for Uryuu's determination to stand by Ichigo and work with the shinigami despite quincies and shinigami being traditional enemies, Kaien's demise is the reason why Rukia opened up the path to power for Ichigo in the first place (and continues to guide her decisions after she replaces him as 13th division lieutenant), and the death of Hisana is the reason why Byakuya adopted Rukia and why Ichigo and Byakuya now possess a bond so unbreakable it can even defy brainwashing. Without those four deaths, this story would have been completely different, or perhaps even non-existent.
** Plot-triggering deaths have been confirmed to have impacted the final arc as well. Both Masaki and Kanae's deaths are tied into the events of the final arc having been caused by [[TheEmperor Yhwach]] performing ThePurge on impure quincies six years before the beginning of the story. The impact of these two deaths on the behaviour and decisions of their husbands (Isshin and Ryuuken) over the intervening years, and subsequently on their sons (Ichigo and Uryuu), are hugely important to the development of the final arc.
* ''Manga/AttackOnTitan'' has several significant deaths that set the events of the story in motion:
** The death of her parents set Mikasa neatly onto the path of becoming TheAce and Eren's protector.
** The death of Carla Yeager not only provides Eren with the desire to destroy all Titans, but leads her husband to take drastic action before disappearing.
** The death of Marcel, a childhood friend of [[ThoseTwoGuys Reiner and Bertolt]] has unseen and far-reaching consequences. [[spoiler: It not only returns Ymir to human form and sets her back on the board as a major player, but is the clue needed for Hange to discover that Titans possess a CannibalismSuperpower]].
** The murder of her mother resulted in [[spoiler:bastard princess Historia Reiss being forced into the identity of Krista Lenz. Her presence in the Survey Corps helps expose the GovernmentConspiracy and makes her vital to their plans to overthrow the government]].
** The deaths of Farlan and Isabel resulted in [[WorldsStrongestMan Levi]] abandoning his life of crime, and laid the framework for his UndyingLoyalty to Erwin.
*** Adding to Levi's story, his mother died when he was a very young child, leading to him being raised by serial killer Kenny Ackerman. Kenny is responsible for most of Levi's character traits: his [[SpringCleaningForever clean freak behaviour]], many of his combat skills (specifically with knives and guns) and [[ArsonMurderAndJaywalking his habit of telling poop jokes]].
** Erwin's father was murdered after Erwin went around saying that his father believed that humanity wasn't ''really'' extinct, as having such opinions is forbidden (turns out he was right, however). This fuelled Erwin's desire to know the truth about humanity and the titans.
** Had Grisha not taken [[spoiler:his sister Faye beyond the walls of the Eldian ghetto and unknowingly gotten her killed by Marley officers, he would have never joined the Eldia Restoration Movement and eventually end up on Paradis Island, the setting of the story. He also never would've met Kruger, the officer responsible for saving Grisha from becoming a mindless titan and giving him the Attack Titan's powers. And he would've never met his first wife Dina, with whom he had his son Zeke - the Beast Titan.]]
* In ''Manga/PandoraHearts'', [[spoiler:Lacie’s death caused Jack to form a contract with Oz, the B-rabbit, which caused the Tragedy of Sablier, in order to bring the world to Lacie in the depths of the abyss. The contract forced Oz to be brought 100 years later along with Jack, although Oz remembers nothing about it, causing him to seek the truth about his own existence, which is why the story happens.]]
* ''LightNovel/TokyoRavens'': The [[HeroicSacrifice death]] of [[KillTheCutie Hakuto]] prompts Harutora to become an [[MagiciansAreWizards onmyoji]] to fulfill her wish.
* In ''Manga/KeymanTheHandOfJudgement'' the brutal murder of Lockville City's champion, the titular Keyman, starts the plot.
* The death of Ryuko's [[spoiler: and Satsuki's]] father sets off the plot off ''Anime/KillLaKill''.
* ''Manga/FairyTail'':
** Almost every single major event in the story is the result of the death of one person. [[spoiler:That person is the main protagonist himself, Natsu Dragneel. Four hundred years before the current storyline, a young Natsu died in a dragon attack with his parents. His older brother Zeref Dragneel, [[{{Necromantic}} desperate to revive him]], immersed himself in the study of forbidden and taboo magic. He was cursed for his willingness to bypass the boundary between the living and the dead by the JerkassGod Ankhseram, and would come to be known as the strong and most evil mage in history. Zeref would create several demons to kill him that would later wreak havoc on the world (such as Deloria, who would kill Gray's parents and his mentor Ur), and many antagonists throughout the series are dark wizards who (mistakenly) seek to revive/summon him in hopes of attaining his power. Ironically, it seems the only thing Zeref was ''not'' responsible for in some way was Acnologia -- many in the series are convinced that he turned Acnologia into a dragon, but in reality Acnologia's transformation was a consequence of Dragon Slaying magic, which was created by Irene Belserion. In fact, some of the major events Zeref is responsible for were the result of his plan to ''stop'' Acnologia]].
** The death of Fairy Tail's first Guild Master Mavis Vermilion has a significant impact on the plot, though minor in comparison to the above example. [[spoiler:Especially considering the fact that [[NotQuiteDead Mavis is (technically) still alive]], as an AstralProjection. Precht/Hades, in his attempts to revive her, turned her body into the eternal magic, "Fairy Heart" aka Lumen Histoire. His failure to achieve his original goal is implied to what have driven him to villainy and create the dark guild Grimoire Heart. Ivan Dreyar is implied to have tried to use Fairy Heart for his own ends, which led to him being ex-communicated from the guild, and spread the information around, eventually attracting the attention of the Alvarez Empire. Finally, there is Zeref, her "killer", who was in love with her. Losing Mavis the way he did, after he allowed himself to believe there was someone out there he could care for and be happy with, was his true StartOfDarkness and led to him [[ThenLetMeBeEvil becoming the evil wizard the rest of the world feared so much]]]].

** In ''Literature/AGameOfThrones'', Jon Arryn's death is what causes Eddard Stark (and by extension, the rest of his family) to become involved in the main plot.
** The Iron Islands plot in ''Literature/AFeastForCrows'' is triggered by the death of Balon Greyjoy, which happens offscreen during the events of the previous book.

The lengths he goes to in order to obtain evidence to prove his innocence and to expose the real murderer cause him to learn revival magic to bribe/threaten his fellow knights into secrecy, which causes another church to interfere in the next book. Had he not met the head of that church, he wouldn't have been called in to help in book 3, etc.

** The show uses this in [[{{Recap/DoctorWhoS32E1TheImpossibleAstronaut}} The Impossible Astronaut]], which kicks off the plot arc of Series 6. The character who dies is the Doctor himself, and apparently permanently. Subverted when it turns out he was FakingTheDead.
** The main Series 7 arc is also launched when the confirmed new companion Clara is killed off in her second episode. Of course, it's not that she died and more that this was the second time the Doctor saw her die, making him realize there's something weird going on. Because, you know, the same person on two different planets and two different time periods died.
* Mary Winchester's death in ''Series/{{Supernatural}}'''s [[Recap/SupernaturalS01E01Pilot pilot episode]].
* In the first episode of ''Series/{{Farscape}}'', when Crichton travels through the wormhole into that strange new part of the universe, his craft accidentally collides with a Peacekeeper vessel at the other end, killing its pilot, who is soon identified as Peacekeeper Commander Bialar Crais' brother--which sets up Crais' vendetta against Crichton for the rest of the season.
* ''Series/ViudasEHijosDelRockAndRoll'' began with a flashback in 1992. Miranda had a romance with Diego in Villa Gesell, and everything was fine... until her best friend Sandra [[MayDecemberRomance seduced Roby]], Miranda's father. Miranda tried to see Diego again at the Buenos Aires obelisk, as planned, but he failed to meet her in time (and, trying to give mistery to their first date in Buenos Aires, they did not exchange adresses or phone numbers). She renounced to everything related to Rock and Roll, swore to never interact again with the dreaded Sandra or Roby, and started a romance with Segundo, a delicate high-society boy. End of flashback. Now, in the present, Roby has died. Miranda is now the heir of Roby's rock radio, she has to work alongside Sandra (Roby's widow) on a daily basis, and Diego saw her in the funeral and finally located her after so many years.
* September 11 caused Reese to become an assassin and Finch to build [[MagicalDatabase The Machine]] in ''Series/PersonOfInterest''.
* David Palmer and Michelle Dessler are killed at the start of ''Series/TwentyFour'' season 5.
* ''Series/TwinPeaks''. "Who killed Laura Palmer?"
* ''Series/PushingDaisies'' began with the death of Chuck and Ned resurrecting her.
* ''Series/{{Chuck}}'' begins with his ex best friend and super spy Bryce getting killed but not before sending him The Intersect.
* Mary Alice's suicide in ''Series/DesperateHousewives''.
* George dies at the start of ''Series/DeadLikeMe'' and the rest of the series is about how she must adjust to her new life as a grim reaper and how her family must deal with her death.
* ''Series/TheWire'' kicks off its initial investigation with D'Angelo skating over a murder charge.
* ''Series/{{Weeds}}'': The untimely death of her husband is what pushes Nancy to sell marijuana.
* One of the first subplots in ''Series/{{Rome}}'' was the death of Caesar's daughter and Pompey's wife Julia. Pompey marrying someone who was not Caesar's relative was the first sign that they have become enemies.
* ''Series/{{Heroes}}'' begins with Mohinder going to New York to investigate the death of his father.
* Series/{{Arrowverse}}
** ''Series/{{Arrow}}'': Every single PlotTriggeringDeath somehow stems from the first entry, Rebecca Merlyn, and caused a season's worth of problems. Seasons 1, 3, and 5's can be chained together, while Season 2's is only connected to Season 1's. The only season that ''wasn't'' the result of a death, from either Oliver's five years away from home or previous seasons, was Season 4.
*** The death of [[TheLostLenore Rebecca Merlyn]] twenty-one years before the start of the series is the very impetus for the entire show. If she hadn't died, then her husband Malcolm Merlyn wouldn't have gone insane in trying to avenge her death with the Undertaking and try to kill his best friend Robert in order to stop him from trying to prevent it, resulting in Oliver Queen being stranded on Lian Yu for five years and becoming the Arrow.
*** Shado's death on the island is what prompts the events of Season 2. Slade Wilson, who loved her, is driven insane by the Mirakuru, and Oliver's role in her death twists his mind and causes him to direct his rage at Oliver, his friends, his family, and ultimately Star(ling) City as a whole.
*** The death of Sara Lance causes the events of Season 3. Malcolm Merlyn ([[OverarchingVillain as always]]) brainwashes his daughter Thea into killing her, forcing Oliver to take the blame and in turn, pique Ra's al Ghul's interest. Sara was later revived at the beginning of Season 4.
*** [[spoiler:Ra's al Ghul's death is the trigger for Season 5, as his daughter Talia was so enraged by it that she trained BigBad Prometheus to help her take revenge on Oliver]].
** ''Series/TheFlash2014''
*** The murder of Nora Allen fourteen years prior to the start of the series drives most of the plot of Season 1, as her son Barry's main goal is to solve it so he can get his father Henry, who was wrongly convicted for her death, out of prison.
*** Henry Allen's own death towards the end of Season 2 breaks Barry enough to create the alternate timeline Flashpoint, the consequences of which drive most of the plot of Season 3.
*** [[spoiler:Iris West's premature death at the end of Season 3, as foretold in the midseason finale, was a result of Flashpoint, and also serves as a PlotTriggeringDeath. More specifically, it acts as the lynchpin for a StableTimeLoop that ensures the existence of BigBad Savitar. When her death is prevented in the season finale, the loop breaks and Savitar only has a few hours left before the paradox catches up to him and he ceases to exist]].
** ''Series/LegendsOfTomorrow''
*** Rip initially gathers the Legends in order to prevent the deaths of his wife and son at the hands of Vandal Savage.
*** Eddie Thawne's death in the Season 1 finale of ''The Flash'' is the indirect cause of Season 2, as it turned his descendant Eobard Thawne into a time remnant and thus a target for the Black Flash, forcing him to create the Legion of Doom to search for the Spear of Destiny, or face certain non-existence.
* In Series/AgentCarter, the murder of Jane Scott in the [[Recap/AgentCarterS2E1TheLadyInTheLake first episode of Season Two]] kicks off the plot, with Peggy being sent to LA to investigate both the death and the bizarre circumstances the body was found in (fished out of a frozen lake... in the middle of a Californian summer).
* ''Series/Daredevil2015'':
** The plot of season 1 is kicked off when Karen Page gets framed by Wilson Fisk for murder, and Matt and Foggy seek to clear her name.
** The plot of season 2 is kicked off by a massacre of Kitchen Irish members courtesy of Frank Castle.
* ''Series/JessicaJones2015'': The main plot of season 1 is instigated by Kilgrave ordering Hope Schlottman to kill her parents in front of Jessica.
* ''Series/LukeCage2016'': Everything in the plot unfolds due to a group of Harlem street thugs shooting up a gun deal between Cottonmouth and Domingo. Cottonmouth's efforts to recuperate his losses end up causing Luke Cage to start coming after him.
* ''Series/ThePunisher2017'': The whole plot of the show was kicked off as the result of Frank's execution of Ahmed Zubair on the orders of William Rawlins. Because he was mistaken as the mole who leaked the tape of the execution to Micro (instead of Gunner Henderson, the actual one doing the filming), Frank's whole family is killed on Rawlins' orders, which leads to the plot of ''Series/Daredevil2015'' season 2.

[[folder: Theatre ]]
* OlderThanSteam: ''Theatre/{{Hamlet}}'' begins with the king's death (though the dead man also appears as a ghost).
* Another Shakespearean example: the murder of the Duke of Gloucester (before the start of the play) in ''Theatre/RichardII''. We never learn exactly who did it, but we do learn that King Richard himself was behind it, and his actions to prevent that fact being discovered, sets the rest of the play in motion.
* ''Theatre/{{Chicago}}'': Roxie Hart shoots her boyfriend, which is what lands her in prison and on trial for murder.
* ''Theatre/ARaisinInTheSun'' involves an inner-city black family's conflicts over how to spend a life-insurance check following the death of the father.

[[folder: Video Games ]]
* Robert's death in ''VideoGame/TheLastOfUs'' has set off a chain of circumstances that leads to Joel meeting up with Ellie. If it wasn't for Robert selling the guns to the Fireflies (without Tess and Joel's permission), Joel would never have met Marlene, the Leader of the Fireflies. And if Joel never met Marlene, he would never have to escort Ellie to safety out of her request.
** Even earlier, [[spoiler: if Sarah hadn't died at the beginning, the game would probably just be about Joel & Sarah trying to survive every day life & Joel never would've met most of the rest of the cast.]]
* In ''VideoGame/{{Xenoblade}}'', the [[StuffedintotheFridge death of Fiora]] in the hands of the Mechon in the first moments of the game is what inspired Shulk and Reyn go ahead and kick [[MechanicalMonster Mechon]] ass [[RoaringRampageOfRevenge in order to avenge her]]. As time passes, everything starts getting much more complex than that.
* President Al-Fulani's execution in ''VideoGame/ModernWarfare'' and Dmitri Petrenko's death in ''VideoGame/CallofDutyBlackOps''.
** Will Irons sparked Jonathan Irons's, CEO of [[PrivateMilitaryContractor Atlas Corporation]], involvement in the story of ''VideoGame/CallOfDutyAdvancedWarfare'' [[spoiler:(although given the fact Irons is sitting at the helm of the world's largest standing military and dislikes government militaries even prior to the game, things may have happened with or without Will's death)]].
* Cave Johnson's death can be seen as this for the ''VideoGame/{{Portal}}'' franchise. His death sparked the creation of [=GLaDOS=], which in turn caused the creation of Wheatley, and the plot of ''Portal''.
* Your guardian Gorion's death at the start of ''Videogame/BaldursGate'' (the first game) kicks off the plot (as well as Bhaal's once more of the plot is uncovered...).
* As the page quote shows the plot of ''VideoGame/EternalDarkness'' is set off by the death of the main character's grandfather, which leads Alex to his house and to find the [[TomeOfEldritchLore Tome Of Eternal Darkness]] which serves as a framing device for previous characters' struggles in the fight (who might also count as this trope, given they have a tendancy to die [[AndIMustScream or worse]] at the end of their chapters).
* The plot of ''VideoGame/GrandTheftAutoSanAndreas'' starts when CJ comes back to Los Santos after five years in Liberty City to attend his mother's funeral.
* ''VideoGame/EchoNight'' begins with Richard learning that his father perished in a house fire. While searching for anything that might be salvaged from the ruins, he discovers a secret passageway to a room containing a strange painting, which drags him back onto the deck of the Orpheus and strands him there.
* The main plot of ''VideoGame/TheElderScrollsIIIMorrowind'' is kicked off some 4000 years prior to the time the game takes place with the death of Lord Indoril Nerevar. His death, the subsequent events of Dagoth Ur and the Tribunal using the Heart of Lorkhan to obtain divinity, and his prophesied {{Reincarnation}} are the driving force behind the game's plot.
* North Vandernot in ''VideoGame/BeTrapped''. He left the bulk of his estate - including [[ArtifactOfDeath the Bloodstone]] - to his niece, May, who lived in New York.
* Jade Champion in ''VideoGame/{{Interstate 76}}''.
* In ''VideoGame/TheCatLady'', the Queen of Maggot's plan to exterminate the Parasites is only set into motion once Susan, the protagonist, takes her own life.
* ''VideoGame/GhostTrick'' starts with [[DeadToBeginWith an already dead Sissel]] discovering the powers of the dead he's been granted, looking forward to use them to solve the mystery of who he was. As he progresses, it is discovered that the entire chain of events that lead to the current situation also started off with a pair of deaths. Namely, [[spoiler:the BigBad's "death" caused by [[MagicMeteor the Temsik meteorite]] ten years before, and the subsequent suicide of his fiancée, driving him to madness and a revenge plot]].
* ''Franchise/FatalFrame''
** ''Fatal Frame III'': Kaname Ototsuki's death. He snuck into the temple where his lover was lying, covered in the Holly tattoos, and woke her up. [[spoiler:Kaname is killed in front of Reika's eyes, which causes the Holly to enter her eyes and not only force her to replay her lover's death in front of her eyes until she's appeased, but also released the Rift into the temple, killing hundreds, and pull people into the Manor of Sleep.]]
** ''Fatal Frame V'': The Maidens of the Black Water were brutally killed, which was psychically and emotionally felt by Ouse. [[spoiler:Their death and regret, along with her own desire to ''live'' with Kunihiko Asou instead of simply dying with him, caused her ritual to fail and doom Mt Hikami.]]
* ''VideoGame/{{Bayonetta 2}}'' kicks off with Jeanne sacrificing her soul to save Bayonetta from [[TurnedAgainstTheirMasters an out of control demon]], which causes Bayonetta to go find a way to Inferno to rescue her.
* The death of the Balance Guardian Ariel kicks off the ''VideoGame/LegacyOfKain'' saga.
* ''VideoGame/{{Far Cry 4}}'''s plot is triggered after the death of Ajay's mother, who wishes to have her ashes scattered through Kyrat. However, he finds in the midst of a civil war.
* ''VideoGame/CommandAndConquerTiberiumWars'' begins with Nod destroying the GDI satellite Philadelphia and killing GDI's leadership. ''Kane's Wrath'' revealed [[spoiler: it was to make sure Redmund Boyle would become GDI's director and Nod's UnwittingPawn]].
* ''VideoGame/{{Vigilante 8}}: 2nd Offense'' begins with the newly reformed Coyotes killing the Vigilante leader Convoy.
* ''VideoGame/{{Fahrenheit}}'' (Indigo Prophecy in the US) starts with the player character committing a murder while under a trance. You have to clear his name, and also play as the cops who are investigating the murder.
* ''VideoGame/TheInfectiousMadnessofDoctorDekker'' hinges on one of these. The player character is trying to solve Dekker's murder while simultaneously treating the psychological patients he left behind.
* ''VideoGame/{{Undertale}}'' is what it is mostly because [[spoiler: the first Fallen Child]] died a long time ago. Their death (well, the side-effects of their ThanatosGambit) is the reason there's a standing order to kill all humans who enter the Underground and why Toriel ([[spoiler: the child's adoptive mother and the former queen of the Underground]]) lives in the Ruins.
* ''VideoGame/TalesOfBerseria'' only happens because Velvet's little brother [[IllBoy Laphicet]] is killed as a HumanSacrifice by the BigBad during the Advent, setting up for her quest for {{Revenge}}. [[spoiler: It ultimately turns out the ''real'' PlotTriggeringDeath is [[TheLostLenore Celica Crowe]] dying in the Opening, aka Artorius Collbrande's wife back when he was "Arthur". Since she was pregnant at the time, her and Arthur's unborn son was used as the first HumanSacrifice to unlock part of the seal on [[LightIsNotGood Innominant]]. And then [[ManipulativeBastard Melchior]] showed up and encouraged Artorius to take the first steps to his vision of "order" and "reason"...]]

[[folder:Visual Novels]]
* Sayoko Robbin's murder at the beginning of ''VideoGame/AnotherCode'' sets her husband off to finish her invention and, later, her daughter to go and clean up their messes.
* Played straight [[spoiler:and subverted]] in ''VisualNovel/HotelDuskRoom215''. The death of Bradley's sister Mila sets him off on his plan to take down Nile, followed by his [[spoiler:faked]] death at Kyle's hands to prompt Kyle to find him and unravel the mystery behind it all.
* The death of Gregory Edgeworth could easily be one of these in the ''Franchise/AceAttorney'' series. Basically, it was his death that kickstarted Miles' ambition to be a lawyer, which started Phoenix's. You could even go further back and say that it was Isaku Hyodo's death that led to Gregory's, and so on. Gregory's death was also the distant catalyst for Misty Fey's disappearance (which in turn had ''several'' repercussions on the Fey clan, such as Dahlia and Iris's father leaving, Mia's PromotionToParent, etc, Yanni Yogi's ObfuscatingStupidity, etcetera).
** In fact, a lot of deaths in this series have kicked off new arcs and plots (Mia Fey, Magnifi Gramarye etc). This makes sense in a world where it's AlwaysMurder.
* ''VisualNovel/{{Snatcher}}''. Jean-Jack Gibson's death leads Gillian and Metal Gear to investigate what he was doing before his [[OffWithHisHead gruesome end]]. This leads right into Gillian resuming Gibson's investigation on where the Snatchers are being built in Neo Kobe City.
* While [[KillEmAll many deaths occur]] in ''VisualNovel/UminekoWhenTheyCry'', it turns out that there was the death of one person in particular that was really responsible for setting the events of the series in motion: Beatrice Castiglioni, Kinzo's secret lover, who [[DeathByChildbirth died from giving birth]] to their daughter, Beatrice II.
* ''VisualNovel/NineHoursNinePersonsNineDoors'' plays with this. While not immediately obvious, through the game you find out about a death of a girl 9 years prior to when the game takes place, and it later turns out that said girl's death is the reason behind [[BigBad Zero's]] plan. [[spoiler: The girl is later revealed to be Akane, and Zero intends to use {{mindlink|Mates}} between her and Junpei to send information she needs to survive [[MentalTimeTravel to the past]] to ''prevent'' her death.]]

[[folder:Web Original]]
* The Human Prince in ''WebOriginal/ElfslayerChronicles'' has a Plot ''[[OffTheRails Derailing]]'' Death. The plot the DM had planned was an escort mission to bring him home to his kingdom to stop the war between them and the Elven Kingdom. However, one of the players decided to instead murder him and frame his elvish lover, turning the plot into a murder mystery/ XanatosGambit on the part of that player.

[[folder:Real Life]]
* While it's almost certain that ''something'' would have touched it off sooner or later, the assassination of [[https://en.wikipedia.org/wiki/Archduke_Franz_Ferdinand_of_Austria Archduke Franz Ferdinand]] is widely considered the first in a chain of events that led to the outbreak of UsefulNotes/WorldWarI.
