Diabolus Ex Machina

""This is not the convenient plot twist that saves our heroes. This is the convenient plot twist that makes them even more screwed.""

- Ryan MC, Two Evil Scientists

Diabolus Ex Machina (Latin, approx. "demon from the machine") is the Evil Counterpart of Deus Ex Machina: a(n often contrived) twist designed to ensure an extension in the villain's favor, if not a Downer Ending. Do whatever it takes, as long as you make absolutely sure that things get much worse for the protagonists, much better for the villains, or both.

Observers of this trope should note three things:
 * Firstly, note that the Diabolus Ex Machina is often brought in simply because if the villain were to lose, the work of fiction would be over. Like the Deus Ex Machina, it only applies if it comes out of left field.
 * Secondly, like the Deus Ex Machina, a Diabolus Ex Machina does not necessarily occur at the end, but is simply a common find there, and should not be confused for an Ending Trope.
 * Finally, that the Diabolus Ex Machina, when used to make a Downer Ending, is a very common Pet Peeve Trope, even more so than Deus Ex Machina being used for a Happy Ending.

If a movie ends with a Take a Moment to Catch Your Death of the last surviving character, it may be this (depending on sheer unlikelihood). Compare Diabolus Ex Nihilo, Ass Pull, and Cruel Twist Ending. Obviously, compare and contrast with Deus Ex Machina. Likely to be employed by writers who believe that True Art Is Angsty. Not to be confused with a Diablous Est Machina, which may or may not be a Mechanical Abomination.

Anime and Manga

 * Darker than Black. What was that? You thought was going to get a happy end? ...Don't be a fool.
 * MS IGLOO Episode 5:
 * Something happens like this in the Gundam Side-Story Space, to the End of a Flash, where the pilot of the Gundam Unit 5 survives the battle of A Baoa Qu and is returning to the ship....
 * And again in the Gundam Evolve story involving the Dendrobrium Orchis,
 * Angel Sanctuary seems to fall into this trope. Especially when Setsuna finally reunites with his loved sister, a wacko angel girl shoots her and enrages Setsuna, causing The End of the World as We Know It. (The manga goes well past this point. Still plenty of Deus Angst Machina, though.)
 * Inuyasha: when they finally complete the jewel, the well that allows Kagome to travel through time closes, keeping her and Inuyasha apart. Subverted when.
 * in Tengen Toppa Gurren Lagann could be seen as this. Where as the others went out in the blaze of glory that one just comes out of left field. The possibility that it could happen isn't even brought up until halfway through the final battle. Meaning in real time about ten minutes before it happens.
 * Code Geass. Oh so very much. Sure, Mao showed us that a Geass grows stronger with repeated use and a careless user runs the risk of losing control of it. Of course, Zero's Geass just had to backfire at the "everything will get better now" moment, and in the most inconveniently nasty way ever, to boot. Season 2 surpasses it when It's like an Up to Eleven version of Season 1. In both seasons, pretty much every time the Order of Black Knights seems to be winning a battle, you can set your watch to some new Britannian super-Knightmare Frame showing up and sending everything to hell.
 * What makes  incident SO much worse is that Lelouch clearly was about to confess all his wrongdoings to   and leave his villainous ways behind. Only to slip up and stumble right into the Moral Event Horizon without even wanting to. After this you just know
 * Given the number of times Lelouch has horrible events happen right in his moment of triumph, one might expect that he leaves an open place setting at his dinner table just for Diabolus.
 * Sometimes it's like Lelouch WANTS something bad to happen ". . . it's like if i told you to kill all the Japanese." really? Of all the things you could have said?
 * Weiss Kreuz Gluhen never promises better than a Bittersweet Ending, but the final scene of the series is pure Diabolus Ex Machina; having cut ties with everyone he ever knew and left Japan, Aya goes walking down a sidewalk in New York and
 * The final sequence of Kite.
 * End of Evangelion, or even Evangelion in general loves this. In EoE She barely finishes, but it's looking up. The  You could say It Got Worse.
 * While in normal Eva, everything is going fine, if not a tad angsty. Shinji's social skills are improving, Asuka's teamwork is going well and Rei is beginning to show some humanity. A few episodes later and
 * A similar scene occurs in L/R. The bad guys are defeated and one of the partners of the title agency has fallen in love and is all set to live happily ever after.
 * A non-death example... Ojamajo Doremi Naisho: Hazuki has taken an unlikely lead in the final leg of a relay to decide a swim meet... then she suddenly gets a cramp on the way back, allowing the other room to easily win the race.
 * A few arcs of Higurashi no Naku Koro ni have this tendency, although they always have long threads of justification for it. Particular arcs that come to mind are Onikakushi-hen, ; Watanagashi-hen, ; and Tsumihoroboshi-hen,.
 * Higurashi Kai does even better than that. In Minagoroshi-hen, Although that chapter title (It translates to ) is a bit of a tip-off...
 * Palm goes to Higurashi Rei.
 * Occurs in the Buu Saga of Dragonball Z, when Mr. Satan/Hercule, of all people, manages to stop Buu by befriending him. Just when things are about to calm down, two gun-toting assholes show up and shoot both Mr. Satan/Hercule and the puppy Buu adopted, pissing him off and forming the Evil Buu, which starts the next part of the arc up.
 * The anime changed this a bit so it wasn't completely out of left field: Mr.Satan did stop them before when they shot the puppy, but one of the goons came back for vengeance. The timing of the whole thing does feel a little contrived though.
 * Also part of Dragonball, is the final saga of Dragon Ball GT. Following the defeat of Super Android 17 when the gang gathers the Dragonballs, they discover that Despite the debate on GT's canonicity in the franchise, the foreshadowing of Old Kai in Dragonball Z might have been a hint of things to come. Furthermore, they do show the balls cracking during the Super Android 17 fight and the characters mention said cracks when collecting them, so it's not like it comes ENTIRELY out of nowhere.
 * Also during the Saiyan Saga during Goku's fight with Vegeta. Pretty quickly Goku finds that the only chance he has of winning is to use Kaioken attack at levels where physically hurts him. After their famous Beam-O-War, Goku finds the only way he'll win using the spirit bomb, despite Vegeta losing said struggle. In a big case of It Got Worse, Vegeta reveals a previously unmentioned way to turn into a Oozaru and promptly crushes Goku within an inch of his life. One wonders why his flunky Nappa didn't use this.
 * Because 1. He probably didn't have this skill, and 2. They were expecting the Earth's natural moon to show up if things ever went south. Of course, Piccolo blew it up expecting them to do this. Still, Vegeta using this ability came out of nowhere.
 * In the Frieza saga, this appears, though is more so in the anime. Piccolo is fighting Frieza in what is presumed to be his true form, losing, then powers up to full strength. Whether or not this would have made a difference because Frieza reveals he has two more transformations, transforms into the first one and demolishes Piccolo. In the anime, Piccolo manages to take the upper hand, then Frieza transforms.
 * The ending of GaoGaiGar Final is all lined up for the happy ending we were all expecting from the generally upbeat tone of the series, then in the last five minutes of the last episode for absolutely no reason at all.
 * There was originally a sequel in development that got canned that would've linked the GGG verse with Betterman more. Part of the development involved Genesic GaoGaiGar erupting out of the Sun.
 * The Wham! Episode in Mai-Otome throws one of these in toward the end. At the end of the previous episode, Arika, Nina and Erstin are ready to take on their quests to become great Otomes as a team, even in the wake of Schwarz's hostile takeover of Windbloom. However, there's still air time left to kill, so along comes John Smith to spoil the party by revealing . At around the same time, Sergey comes by to congratulate Nina on a stellar year, he drops a custom-made handkerchief given to him by, which sends Nina into a jealous rage, sparking a fight that ends with . As later episodes show, it doesn't get much better for Nina from there, either.
 * It'd be a shame to leave out Ga-Rei Zero. Most of the major events that occur only happen in order to screw up everyone's lives even more than they were before. It always gets worse, save for a little spot of hope that Kagura ends up dealing relatively well with her duty fighting against monsters in the epilogue.
 * Occurs in the second season of Magic Knight Rayearth, to complete the Hope Spot for Hikaru and Eagle—having defeated Nova and saved Lantis, the Knights and Eagle return to Cephiro only for Debonair to show up out of nowhere to kill the Autozam commander. Especially jarring since Debonair had never actually attacked anyone directly until this moment.
 * Used quite well to make a point in Black Jack when Dr. Kiriko first appears. A woman with a terminal, inoperable condition has requested that Kiriko euthanize her. As this runs directly counter to Black Jack's principles, he begins meeting with the woman in an attempt to figure out a cure. He and Kiriko meet with each other, and Black Jack delivers a speech about how wrong Kiriko is to do what he does. After the operation goes through, with Kiriko present, Black Jack asks after the patient.
 * Kiriko laughs? Black Jack curses the heavens. In fact, thanks to the new releases of Black Jack manga, it can be seen that just about one fourth of his cases end like this. A running theme seems to be that even the world's best doctor isn't omnipotent.
 * This isn't just restricted to Black Jack, either- many of Osamu Tezuka's works feature such occasions. The 1980 Astro Boy anime, for instance, has many bit characters who exist only to die so that Astro can question why humans made robots this way.
 * My-HiME actually had a Diabolus with a name: Miroku, However, the ending actually has, causing the first ever destruction of Diabolus by the direct actions of the protagonists.
 * Faust from Shaman King has the unfortunate distinction of getting one in his origin story. He works for years to save his wife from a terminal disease, finally succeeding a few months before a burglar shoots her.
 * At the end of Cowboy Bebop, Spike finally finds his lost love Julia,.
 * Subverted in Fist of the North Star. When Kenshiro gains the upper hand on Shin during their final battle, Shin attempts to discourage him by stabbing Ken's fiancee Yuria in the chest. Later Ken finds out that the Yuria stabbed by Shin was actually a mannequin and that the real Yuria was no longer with him.
 * Kurokami ends in this way, in the last minutes of last episode everyone discovers that final sacrifice is required, even if nobody dies.
 * Tsukihime. "And then Arcuied blew Roa into tiny pieces. Her and Shiki have a long, happy life in store as Shiki shows her all of the things she never thought to experience, and their mutual love is sure to last fore- SLICE."
 * In the FRLG arc of Pokémon Special, yay! The good guys defeat the bad guys, stop an airship from crashing into Vermillion, free Deoxys to let it go where ever it wants, have a happy reunion of sorts... then WHAM! They get Taken for Granite.
 * Several in Rave Master. Gale, after failing to talk down King, asks to government to arrest him, but they shoot down his family instead. King and Gale manage to end the cycle of war between the Raregroove and Symphonia family with a Heroic Sacrifice, only for King's Axe Crazy son to turn up and start the cycle back up. In order to defeat Endless Elie not only has to but must also . Etc.
 * At the end of the Super Robot anime Space Warrior Baldios,
 * In episode 278 of Bleach, we have coming out of nowhere
 * The final fight with Aizen.
 * Death Note: At the end of the Yotsuba Arc,
 * In Pokémon: Sinnoh League Victors, Ash is finally so skilled a trainer that only 3 of his League matches are shown, the rest briefly touched on in a montage. Just as he, in comes Tobias, aka the Darkrai Trainer, who proceeds to curbstomp Ash thoroughly in minutes. This serves no purpose to the plot whatsoever, other than to keep Ash from winning a League tournament.
 * In the opening two-parter of Pokémon: Best Wishes, Zekrom appears purely in order to shock Pikachu and screw up his ability to use Electric attacks (catching both him and Ash off-guard and causing him to lose to a newbie), provide a 'climactic' cliff-hanger which is resolved within the first minute of the next episode, and then disappear.
 * In Panty and Stocking With Garterbelt,
 * A minor example of Ai Kora: Hachibei's plan of making Tsubame wear boots filled with clay so he can make a mold of her feet and ankles fails when she lets a friendly rival male driver she just met in that chapter wear her boots, just because she thought they were comfortable. Because when your first meet someone, naturally you exchange footwear, of course!
 * Shin Mazinger Shougeki! Z-hen has a pretty brutal one at the end.
 * This is based on the ending to the original Mazinger Z, which had the Mycene Empire come out of nowhere to wreck the titular robot, only for Great Mazinger to equally come out of nowhere and save Kouji.
 * Fairy Tail ends the Nirvana arc by arresting the reformed, and heavily implying that the latter will be executed (he does get a deah sentence later too), then proceeds to top that by revealing that everybody the Token Loli grew up knowing, with the exception of one man who was Dead All Along were just illusions created to keep her comapny and she'll never see them again. Never one to out do itself, Fairy Tail then ends the S-Class arc with

":"
 * Let's be honest here - Marvel Zombies is this trope.
 * It's also a favorite of The Walking Dead. Was it really necessary for Rick to  Not really, but it makes everyone reading it feel horrible.
 * A pretty stupid one from WITCH. Early in the series, the team's defeated Nerissa and, as an added bonus, made sure Will's deadbeat dad doesn't try to swindle money from her or her mom. As Will and her mother go to celebrate being safe from the latter, Will's dormouse races out of the house and gets ran over by a car. It's kind of hard to not presume Will's next quote, "Why does this keep happening?" wasn't a massive Lampshade Hanging to all of her problems at the time.

Truman eventually decides that this is really a ridiculous idea and signs an executive order allowing for blacks to become battleships. Or he would have, if the Germans didn't choose this exact moment to blow up the White House.

Fan Works

 * The cheesy yet fairly popular Half-Life fanfic series, Half Life: Full Life Consequences, uses this as a Sequel Hook: The first installment ends with "the next boss" coming out of nowhere and stepping on Gordon Freeman, setting up for a sequel that centers around John Freeman hunting down the next boss. Adding to the bizarreness, our heroes had just defeated the "Final Boss", which by all rights should preclude any more bosses showing up.
 * To be continued...?
 * And the second installment, after the defeat of the evil boss, ends with the dead Gordon Freeman becoming a zombie goast.
 * This is followed up with a glorious Deus Ex Machina in the third chapter, when even further into the future, John Freeman descends from the heavens to assist his son in defeating the Combines and sending them back to science and outer space.
 * Voyager Virtual Season 8 uses one of these after the crew is almost home, getting them lost again in order to fix a few plot holes as well as to set up a more satisfying climactic battle in Virtual Season 9.
 * The Powerpuff Girls Dark Fic series Immortality Syndrome has several of these, but the biggest comes in Immortality Relapse at.

Film
"Lloyd: "Do you realize what you've done!" [runs off and flags down the bus] "You'll have to excuse my friend. He's a little slow. The town is back that way.""
 * Carlitos Way. The producers and bigwigs . In the commentary, the filmmakers joke about whether or not to shoot the "Bullet Proof Vest Scene" before even showing the current cut to their higher-ups for approval.
 * City of Angels. Less than a day after a fallen angel has given up his immortality to be with the mortal woman he's fallen in love with, she's inexplicably run over by a truck driven by the Diabolus Ex Machina. One might suspect his fellow angels of having summoned it in order to teach him a lesson...
 * The movie-version of Stephen King's The Mist takes this all the way into Deus Angst Machina territory.
 * Even James Bond is not safe from this demonic influence—in On Her Majesty's Secret Service, he drops by to ensure that Bond's marriage becomes a SHORT one.
 * Then again, this does seem to follow naturally from the premise that Blofeld, as shown throughout the movie, is an enormous dick.
 * Director Peter Hunt said that originally the film was to end with the wedding and then the next would start with the assassination and follow from there. However since Lazenby gave up doing the sequels, it wound up in OHMSS. The following movie, Diamonds Are Forever, opens with Bond searching for Blofeld, presumably to avenge the ruined marriage.
 * At the beginning of For Your Eyes Only, Bond is visiting his wife's grave, complete with "We have all the time in the world." MI6 pick him up by helicopter, except it's remote controlled by... a bald man with a cat, who tortures Bond the way he tortured Blofeld in Diamonds Are Forever.
 * It's very carefully structured to be open to the interpretation that it leads on from either You Only Live Twice or On Her Majesty's Secret Service. For one, it opens in Japan, where most of the action of the former occurred. Take that as you will.
 * The ending of Easy Rider was already on its way to being interpreted as a Downer Ending, with Fonda telling Hopper that, despite their financial success, they failed at their goals from a moral and spiritual standpoint. But even that was too ambiguous, so the movie sent a couple of truckers with a shotgun to shoot them both dead for no good reason in the last two minutes of the movie. Closure!
 * The Sean Penn-helmed The Pledge had a particularly brutal example of this, and it also proves that you can make a Downer Ending out of the death of the antagonist. The child-murderer being pursued by Jack Nicholson's character dies in a fiery car wreck, drawing his full share of karma down on his head but ensuring that Jack never fulfills his titular pledge to find him, meaning that all he's risked in the movie, including winning the trust of the mother of the killer's next planned victim, is for nothing (other than the fact that the killer never makes his next hit). We last see Jack's character sitting in front of the rural gas station he owns, rapidly fading into self-hatred and senility.
 * One particular death in Serenity is a downer (especially since ), but another  death falls right into this. He successfully manages to . Joss Whedon mentions that he wanted to break the appearance of Plot Armor on the rest of the characters for the finale, and that the cockpit is pretty much the only place the Reavers could effectively shoot. In fact, the next shot missed Mal and Zoe by a few inches. So many fans will never forgive Joss for this.
 * The brilliant French film Z does this with the ending titles. The bad guys have been caught and are all going to jail, the heroes have won out, freedom is on the march again in Greece, and then we get a news broadcaster discussing how the bad guys all got off light, some of the good guys went to jail for nothing, and, instead of the credits, ending titles listing all the things the military junta banned afterwards in Greece: "long hair on males; mini-skirts; Sophocles; Tolstoy; Euripedes; smashing glasses after drinking toasts; labor strikes; Aristophanes; Ionesco; Sartre; Albee; Pinter; freedom of the press; sociology; Beckett; Dostoyevsky; modern music; popular music; the new mathematics; and the letter "Z", which in ancient Greek means "He is alive!" The book is based on Real Life, and this more or less how things actually ended for Greece after WWII.
 * Diabolus' fickle finger can also be detected in the end of Forrest Gump; simple Forrest has finally achieved all he ever wanted in winning the heart of his troubled childhood sweetheart Jenny, who herself has finally fallen in love with a good man who loves her completely and unconditionally and can give her a good life... . She's perfectly fine at the end of the book, however, though this is remedied in the sequel 'Gump and Co.'
 * In Rise of the Planet of the Apes, the airborne viral agent Caesar used to make the apes smart
 * The ending of the Canadian horror film Cube: The female lead, one of two sympathetic characters in the whole movie, evades every trap, figures out how to escape, is right on the threshold of getting out... The moral? Uh...
 * Cube 2.
 * The ending of Pitch Black. The out-of-nowhere alien grabs the female lead just as she's about to escape. This is played as somewhat karmic, since
 * The Saw series of movies is chock full of Diaboli Ex Machina, some coming within seconds of the protagonist thinking he's found a way out of the nightmare.
 * The third movie is particularly sadistic, but actually gives an explanation for it.
 * The Final Destination movies are built around Diabolus hunting down people who escaped his clutches the first time around and dispatching them in a variety of unpleasant and unlikely ways.

 * The film Whoops Apocalypse! follows a desperate attempt to stop a nuclear war, which would have succeeded were it not for a hypnotist routine being disturbed - a navy officer is programmed to believe there is a large fire in progress when the hypnotist snaps his fingers (desperately yelling 'FIRE!'). Owing to an unfortunate intervention, this is never undone. When the officer receives the good news that the missiles don't have to be fired, he is so relieved that he doesn't respond to the questions being asked - leading to somebody snapping their fingers to get his attention....
 * The Wages of Fear has the only surviving driver from the deadly nitroglycerine convoy plunging to his death on his way home for no readily apparent reason.
 * Cloverfield. Arguably the monster serves as this trope for the whole movie, since it's inexplicably always running into the main characters.
 * Adam Sandler delivers this on himself in the middle of Eight Crazy Nights, by explaining his hate for the holidays with a flashback where a younger version of himself sparks a Miracle Rally for his basketball team.
 * In the Korean melodrama Failan, the male protagonist decides to honor his wife's memory (who he wed for purely financial reasons, and had neglected until her death) by turning his back on his gangster wannabe lifestyle, even turning down a request from a fellow gangster to take the fall for a murder and serve his subsequent prison sentence..
 * Pay It Forward, both infamously and egregiously. That came out of nowhere. AND served NO point. Except to ruin any good feelings you had. And arguably to break the film's aesop.

Just as everything is going smoothly, a series of increasingly unlikely disasters occur, culminating in an electrical fire that destroys Wayne's house and kills Garth while the slimeball villain gets the girl. Fortunately, Wayne and Garth turn out to have other ideas...
 * In The Blue Lagoon, a movie based primarily around emotional and physical self-discovery, Diabolus is personified in the form of a three-year-old boy. Richard is exploring one of the islands in the archipelago while Emmeline is watching over their son. Emmeline nods off to sleep in their rowboat and while doing so, their son Paddy throws one of the oars overboard. Richard swims out from the island and retrieves the oar, but is spotted by a shark. Emmeline throws the other oar at the shark to distract it and Richard is forced to abandon the other one to escape, and their boat is swept out to sea. To make matters worse, Paddy has gotten his hands on a bunch of dead-and-berries, swallowing a handful before his parents stop him. With a dying baby and no hope of rescue, Richard and Emmeline eat the remaining berries...barely hours before a ship with Richard's father (Emmeline's uncle), who had been searching for them for several years, happens upon their boat.
 * In Screamers, the captain survives the Late to the Party, survives the Twist Ending, and makes it to the Emergency Evacuation Pod in time to make it off the planet alive, only to take a cyborg teddy bear along with him for the ride home.
 * Walk Hard's Dewey Cox dies 3 minutes after his last performance.
 * Monty Python and the Holy Grail ends with our heroes assembling an army to fight the dastardly French and reclaim the Grail once and for all. Just as the army begins its assault, modern-day police vans hove into view and arrest everybody, including the cameraman, thus ending the film.
 * This an actually more of a Brick Joke shaped aversion, as the police investigation of the knights is a Running Gag for most of the film.
 * The Phantasm sequels all end with the heroes defeating the Tall Man, only for him to come back and devastate them.
 * Dumb and Dumber plays this for laughs. The girl the duo went halfway across the country to return a briefcase to turns out to be married, and in the final scene, when they encounter a bus full of swimsuit models looking for a pair of assistants to travel with them and oil them up for photo sessions, they (being idiots) direct them to the nearest town.

 * Just to make it worse, doesn't make any sense. The reason she gets trapped is that water is pouring into the ship through the stern hatch, and several bulkhead doors slide shut to contain the flooding. Given that there is only one way for water to get into the ship and the watertight bulkheads are working properly, there is no reason for her compartment to keep filling up.

The warden then tells them that he'll sign the papers to release them the next day.
 * At the end of the 50s B-Movie, The Mole People, Love Interest Adad inexplicably runs back towards the cave entrance during an earth tremor and ends up getting crushed by a collapsing pillar. It turns out this massive Idiot Ball moment was the result of Executive Meddling: Studio execs forced them to kill off Adad because they thought Adad and Dr. Patrick (played by John Agar) would constitute a "mixed marriage" and wanted to avoid encouraging "miscegenation." The woman on the movie poster is Adad, by the way.

 * |Mission: Impossible - Ghost Protocol is full of these. At every turn, the heroes' plan goes wrong, forcing them to improvise and generally making the movie even more tense and awesome. At one point, they are forced to go undercover without their trademark Latex Perfection masks.
 * Haywire has a particularly bizarre one where, in a movie that otherwise strives for realism, the heroine manages to outmanoeuvre her opponents in a car chase only for the car to crash anyway because a freaking deer jumped into it.
 * In the last minute of The Cube, the man finds out that his escape was an illusion and he's still in the cube.

 * One of the biggest flaws of the horror movie The Bye Bye Man is that there's not even the slightest clue as to who or what the eponymous monster is or where he came from. The characters in the movie have no idea, and the viewer certainly doesn't.

Literature

 * The Hapless Child by Edward Gorey is this trope turned Up to Eleven over and over and over again. Bonus points for an ending which seems to be headed towards Deus Ex Machina but goes with Diabolus Ex Machina instead.
 * Animorphs killed a major character in the finale. Fair enough - their lease on survival was well overdue. But then, not content with successfully leaving realistic loose ends arising from what came before, Applegate brought in a completely unheralded Hindu Borg Collective to really ruin her readers' day in the last handful of chapters.
 * Proof that the Diabolus has been around for a long, long time exists in the ancient Greek myth of Orpheus, the bard, who walked into Tartarus to bring back his wife, Eurydice, who had died on their wedding-day. After giving a performance that made the Furies weep, Hades gave his permission for Orpheus to bring her out with him—so long as he walked all the way out without turning around and looking back. The catch? Nobody told him he had to wait before both were outside... For a second, he sees her shade, before she is pulled back to the underworld, crying his name...
 * Some versions of the myth omit the Diabolus and have him lose his nerve for some other reason; thinking that he heard her cry out, for instance, or just plain ol' lack of willpower.
 * Eurydice was happy in Hades because she'd had it up here with Orpheus and his penchant for boring her to tears with his songs and poems. Just as they're almost out of Hades, she asks to hear one of his songs, knowing that Orpheus can't resist this appeal to his vanity.
 * Carol Ann Duffy's version is rather... unique.
 * Tom Holt has a good working relationship with the Diabolus. This is particularly exemplified in Little People, where he introduces an entirely new metaphysical rule just to ensure the Downer Ending.
 * The Epic of Gilgamesh is another of the Diabolus' old-school performances. After Gilgamesh has gone through unbelievable trials to procure a flower that grants eternal life, it's eaten by a snake on his way home. Proof that even the Diabolus Ex Machina cannot resist the classic appeal of being Scaled Up...
 * The Pit and the Pendulum uses both this and Deus Ex Machina.
 * Perdido Street Station by China Mieville's summons the Diabolus Ex Machina with an unholy ritual of Dungeon Punk Thaumaturgy. The fact that two completely separate incidents, with no relation between them, ensures that all the main characters will spend the rest of their days being utterly miserable makes this one of the nastiest examples of the demon's works. Deus Angst Machina was invited to the party, and danced all night long...
 * Mieville's other books, Iron Council and King Rat, do this to a lesser extent. The first involves one of the main characters doing something incomprehensibly stupid that denies the revolution against the tyrannical government of New Crobuzon much-needed reinforcements (though it's implied they wouldn't have won anyway). The second has the reader being informed casually that the children who were the original victims of the Big Bad of the story were condemned eternally to hell alongside him (and the main character essentially doesn't care). Iron Council even has the chutzpah to tack on an epilogue that tries to make it not seem like the complete and utter betrayal that it is.
 * The author has said a happy ending would be a betrayal to reality and the everyday suffering of the oppressed. He believes life is one big Diabolus Ex Machina.
 * Diabolus crosses over with Chekhov's Gun in Midnight Tides (Book 5 of the Malazan Book of the Fallen).
 * The last 3 chapters of Northern Lights, apparently for the purpose of introducing the rest of the trilogy. Shouldn't the author have been concerned with connecting it to previous events as much as upcoming events? Omitted from The Film of the Book.
 * House of Leaves has the moment that Will Navidson, Tom, and Billy Reston finally come upon poor Jed and wounded Wax in the middle of the labyrinth after two weeks, and after . Jed is so happy..
 * Ian Irvine goes all out in his Well of Echoes trilogy (which became a quadrilogy almost, it seems, so Diabolus could strike). The world is saved! All is harmonious! At which point one of the Big Bad whose son explicitly identified him as dead earlier turns up. To top it all off, the heroes then destroy all the world's magic, hoping to overload his personal magic source, but that backfires, leaving him the only one with any real magic in the entire world and the rest of civilization pawns to his whims. All so the author could go on and write a dictatorial dystopian trilogy as a follow up. Go figure.
 * The author loves his cliffhangers, with only one of his fantasy books actually having a proper, satisfactory ending. The others have such glorious situations as No happy endings here, folks.
 * In Warhammer 40,000: Gaunt's Ghosts, is effectively a manifestation of Diabolus. At the end of The Guns of Tanith, he kills off . In Sabbat Martyr, although the fighting is effectively over and the nine chosen assassins have been slain, he is subverted by Chaos psykers into killing Saint Sabbat. Although he does not succeed and, he still succeeds in killing.
 * Poor
 * Hans Christian Andersen, "The Flying Trunk": Things are going well for the beggar guy with the titular trunk with his romance with a princess,
 * Hey, even his "happy endings" can be pretty depressing. "The Little Match Girl".
 * A rather large portion of his fairy tales are actually pretty depressing. "The Christmas Tree" and "The Little Mermaid" come to mind.
 * The Kite Runner, by Khaled Hosseini. The protagonist and his best friend's son are getting along well and all set to move to America when
 * The Princetta: The main characters return from their adventures and are all set to live Happily Ever After, Malva and Orpheus get together...
 * A rare good use: All Quiet on the Western Front. The narrator is hit by a stray bullet on a day so quiet the official report was a Title Drop. It works because we've already established that Fate is a bitch towards soldiers. (The movie adds some Diabolus by making it the final day of the war.)
 * In Robert A. Heinlein's The Cat Who Walks Through Walls. All fictional universes are real alternate universes in their reality. One of the characters points out that a hero (a writer) is not permitted to resurrect the Big Bad of his favorite fictional universe because of this trope. The character asks if the hero can just retire as head of the training school but apparently the risk is that the story will evolve to need a serious villain, who will come into existence if written.
 * The end of the Redwall series book Martin the Warrior does this to a degree that the flashback story it's based on ends on a Tear Jerker. Everything seems great, Of course then it fast forwards to the present day in Redwall where everything is okay and they discuss how Martin founded Redwall and was a great hero. But it still puts a damper on the entire ending and is one of the few Redwall books to do this.
 * In Meredith Ann Pierce's Darkangel Trilogy, Aeriel and have finally become an official couple after two years of Will They or Won't They?. So of course  Nobody's too happy about this except the child bard who gets to turn the whole story into a pretty song.
 * Arguably one of the worst examples occurs in the book Final Destination: Dead Man's Hand. After the set up disaster the survivors are being transported by a cop, who dies in a freak traffic light accident (the group manages survive the car going out of control though). At the very end of the book the Final Girl, who thinks she's beat Death and won, gets a call from her doctor, who says she has very advanced HIV, contracted from being splattered in the cop's blood at the beginning of the book.
 * Ellen Hopkins's book Burned throws a completely random to cause an  The author seems contractually required to provide a Downer Ending or Bittersweet Ending because True Art Is Angsty, but all her other protagonists got themselves in trouble with their own actions and not a snowstorm. Note to author: It doesn't count as foreshadowing if you don't foreshadow until five pages before the event!
 * The Ramayana: AFTER Rama rescues his wife Sita, wins the epic battle against the demons, and gets crowned king, he puts her through not one but two trials by fire. Because his subjects believe she might have cheated on him while she was being held hostage. She asks to be - and is - swallowed up by the earth after trial by fire #2.
 * That last part is usually omitted from retellings, for obvious reasons.
 * The Dresden Files book Changes has a very nasty one at the end - after barely managing to win the climactic battle,  However, in the next book, Ghost Story, this is subverted.
 * Seekers, by Erin Hunter. A young polar bear, Kallik, is orphaned and alone. After much wandering and hardship she gets caught by humans, who plan to re-release her alongside Nanuk, a mother who'd lost her cubs, in the hopes that she would adopt Kallik. After some consideration, both bears decide that this is an acceptable arrangement.
 * In Lord Sunday, the final installment of Keys to the Kingdom, Arthur finally collects the 7 Keys. Up until this point, the series has been fairly predictable, although things have been getting kind of real in the background, what with . However, it's here where everything truly goes downhill for Arthur. All he wants to do is end the fighting, but Fortunately, it gets better. It turns out that  The catch?   A series that had been very light-hearted up until this point takes a sudden turn: Arthur went on that entire quest with the only result being  The closing dialogue of the main story? "Wow, Arthur! You won!" "Yeah...I guess we won." Freaking. Ouch.
 * In From Hell with love
 * At the end of Harry Potter and the Prisoner of Azkaban it seems as though Harry will be able to leave his abusive foster family to live with his godfather, while an unconvicted criminal will go to jail. Then  turns into a werewolf (it just having happened to be the night of the full moon, and him having forgotten to take the potion which would keep him safe), and in the confusion the criminal escapes.
 * Though Trelawney did predict it a chapter before it happened, so anyone keeping track knew how it would turn out.
 * At the very end of "Nuclear Holocaust Never Again", the second book in the "Never Again" series by R. J. Rummel, things are looking pretty good. The heroes have managed to Set Right What Once Went Wrong and have confronted the parents of the at-this-point still an infant villain, who have willingly let the heroes adopt him so that he doesn't grow up to become a nuclear-war-causing dictator. Then,  At least the world is safe,
 * Shows up in ''Shiver' in the form of, of all things.
 * The Green-Sky Trilogy: Yay! The children have been found, the last of the old-guard Ol-Zhaan has rendered himself harmless through excessive narcotic use, the Erdling radicals have been jailed, the two races are finally figuring out reconciliation and want to make it work. All we need to do is make this mostly symbolic gesture of destroying the last weapon...oops. Fortunately, Snyder wrote and charted a Canon sequel to her books in video game form.
 * The Count of Monte Cristo lampshades and ends up subverting the trope. Initially Dantes blames God and fate for all the terrible things that occured to him, but with the help of a fellow inmate, is able to reason out how certain people wanted him to suffer, not God. Thus, it becomes a core part of his philosophy that once he breaks out, he can't count on Diabolus to hand out random punishment. It has to be up to him.
 * The ending of Malevil tastes a little of this, because of a Distant Finale. Some 575 pages are spent on a six-eight month period and the final 20 pages are a 3-year epilogue. More tragedy strikes in the final pages then the whole novel before because it covers a much larger span of time.
 * At the end of My Sister's Keeper, Anna finally gets medically emancipated from her parents...
 * Bridge to Terabithia: all goes well for Jess, he finally warms up to using his imagination... and then
 * Not so contrived, actually; the best friend of Katherine Paterson's son, inspiring Paterson to write Bridge to Terabithia.
 * The end of Part 1 of The Sex Gates. Lee and Rita are going to have a baby, Rita is finally opening a facility that should make the lives of technologically-deprived poor people much better... and then one of those same poor people fatally stabs her when he's supposed to be shaking his hand. They're forced to push Rita through one of the titular gates, which saves her life at the expense of turning her into a man and destroying her unborn child in the process - and Lee loses his balance and falls through as well, turning into a woman.
 * The Jungle is made of this, at least until Jurgis discovers Socialism. Even then, the original ending had one of these come out of absolutely nowhere in literally the last sentence of the book to render the entire novel completely pointless. This ending was ultimately cut.

Live Action TV
"Kate: I was sure I was going to die before-- (Boom! Headshot!)"
 * Buffy the Vampire Slayer
 * Poor little Cassie from "Help", rescued effortlessly from both an evil cult and arrow booby-trap, only to die from shock due to a heart condition (which was mentioned) as the arrow trap (which one of the villains sets up and discusses) activates. Buffy catches it without even blinking but it is too much for Cassie.
 * Tara was lethally shot through a window and died almost instantaneously while in the middle of the room on the second floor. The gunman was outside on the ground shooting a pistol randomly into the air and yet on pure luck managed a hit so precise that a Marine sniper perched on the opposite rooftop with a rifle would have been hard-pressed to match it. Seriously, this one's a Trope Codifier.
 * Worse. Given where the shooter was standing, where the bullet entered the house (which we clearly see on-camera—its through the lower half of the bedroom window), and where Tara was standing, that shot is not possible by the laws of physics. The bullet would literally have had to make a right-angle turn in mid-air.
 * Two right-angle turns. The bullet enters Tara's back and exits out her chest, but Willow—who is standing directly in front of Tara, and close enough to catch the blood spatter—doesn't catch the bullet as well. Which means the bullet has to either turn or stop in mid-air directly after leaving Tara's body.
 * In one of the Buffy comics, Halfrek the vengeance demon has cursed somebody that every descendent of his will die on their 30th birthday, and to ensure this happens she sends a variety of demons and monsters after one particular descendent. Spike wants to stop her mainly out of spite and figures that if he can keep the guy alive until midnight, he's off the hook. Then, after Halfrek has given up, at one minute past midnight, the guy falls out of a window for no reason, and dies anyway...
 * Tara's sanity gets sucked out, but despite being attended to by Dawn for some time, waits until Glory punches a hole in her wall to start babbling about how Dawn's the glowing green energy girl.
 * Xander is told a lot of nasty things about his
 * Actually inverted in "Doppelgangland" when Evil Vampire Willow from the Wishverse comes to the Buffyverse, gets the I-want-to-go-home going and after saying goodbye the viewer is reminded that she gets back to the exact time she came from, only to.
 * This happens in quite a bit of Cold Case episodes, like "November 22nd", "The Crossing", "The Letter", "World's End", "Forever Blue" ...
 * Jordan (as Diabolus) reveals all the secrets and issues among the main-cast to each other at the Season 1 finale of Scrubs, even though she has quite few to do with the specific persons (Ex Machina).
 * Heroes: Charlie is killed by Sylar for her power. Hiro decides to go back in time to save her, but overshoots yesterday and winds up six months in the past. He develops a strong relationship with her, and she becomes his first love interest. Just before leaving with Hiro for Japan, she reveals she has a blood clot in her brain that'll kill her right around the time Sylar kills her anyway. This rips Hiro's heart into pieces and makes his power go wonky, accidentally putting him in Japan, far away from her, so she stays at the diner and is killed by Sylar anyway.
 * And let's not forget the third season. Hiro (and a newly-reformed Sylar) return to the diner where Charlie worked (due to their time-travel shenanigans) and use Sylar's powers to remove the clot in her brain. Almost immediately afterwards, at the end of the episode she was healed in, she gets kidnapped by the Big Bad and deposited in 1944, thereby robbing Hiro of any potential relationship with her.
 * Happened a second time with poor Hiro, albeit this time less touching and more stupid. He goes back sixteen years, and meets his dying mother. She gives him the catalyst, and he vows to keep it safe from Arthur, who wants to use the catalyst to fuel his army of supersoldiers. Somehow, for no explained reason, Arthur knows that Hiro has the catalyst and teleports exactly to where Hiro and Claire are. He steals the catalyst, sends Claire to the present, and almost kills Hiro.
 * Sylar has benefited from this trope so many times it's not even funny. He technically "died" in Company custody halfway through the first season, but got a mysterious off-screen resurrection. Eden's Compelling Voice and Mohinder's power-disabling serum both worked against Sylar at first, but conveniently and inexplicably failed right when they were about to kill him. In the finale of the first season Niki uses her Super Strength to wail on Sylar with a parking meter, Hiro runs a friggin' katana through his body, and he still survives.
 * The Diabolus has occasionally been employed by The Outer Limits and The Twilight Zone, as indicated above—they have a healthy partnership.
 * A particularly impressive example of their partnership is the episode where an unfortunate, timid man has locked himself in a bank-vault to get the peace to read his many books—and because of that, survives a nuclear holocaust, leaving him the last man alive in the world. Then he realizes that this gives him plenty of time to read his beloved books, and thus unwittingly invokes the Diabolus Ex Machina, who promptly breaks his glasses.
 * In the seaon two finale ("Twilight") of NCIS, the team manages to foil a devious terrorist plot. As they are celebrating their success, Diabolus strikes in the form of a high powered sniper rifle fired by the Big Bad that drills a hole in Kate's head. To add insult to injury, Kate had just taken a bullet for Gibbs and was spared serious injury thanks to her Bulletproof Vest.


 * Blake's 7 is loaded with Diaboli ex Machina. For example, people who say they hate Servalan, and have no reason to like her, keep betraying the protagonists to her, even though she has never rewarded a traitor and kills them each time. In "Rumors of Death," she's been deposed in a revolution, and she's in a dungeon cell, awaiting execution. Avon picks this time to care about anything other than himself, for the first time in the series, avenging his old girlfriend's death. So he frees Servalan in return for information. He makes that a priority over everything else, including winning and safety (usually his highest priority).
 * Servalan is some form of walking Diabolus Ex Machina generator - most grievous example is what was meant to be the finale, her trapped on a ship on the edge of the galaxy that was about to explode, orbiting a planet that was also soon going to explode. Come next season, it is confusingly revealed that somehow the fact that the ship was being eaten apart by a ravenous space virus made the teleport TEN THOUSAND TIMES STRONGER than ever before, and even though she had no idea how to operate it by pure luck managed to land herself NOT in empty space for a start (because the teleport had no safety mechanism to prevent that), and then of all the thousands of possible planets not only a habitable one, not only a populated one, but one governed by her own people... COME ON!!!
 * Just think: if it weren't for the miniseries, this is how Farscape would've ended: And vice versa, since the cliffhanger was pretty much why there was such a demand for a miniseries to begin with.
 * In The West Wing episode "18th and Potomac", the death of Mrs. Landingham, President Bartlet's personal secretary, has Diabolus' fingerprints all over it; after a gentle little running subplot about Mrs. Landingham picking up her first new car, Diabolus arranges for a drunk driver to run a red light and kill her offscreen at the end of the episode with no foreshadowing whatsoever. This also contributes to a bit of Deus Angst Machina, as what with Bartlet's M.S scandal and various other crises and such, it wasn't as if Bartlet didn't already have enough reasons to be a bit angsty at the time. This example, however, can partially be forgiven in that it leads to Bartlet's excellent rant against God in the next episode, in which he even lampshades the trope (see the page quote), and his equally awesome Redemption in the Rain sequence.
 * Another example—a lesser one because it's a newly introduced, comparatively minor character, but still a punch in the gut—is in the next season finale, "Posse Comitatus," when C.J.'s stalker is apprehended and she just begins a relationship with the special agent who'd been assigned to protect her... and he leaves her sight for a minute to pick up a candy bar and a flower from a convenience store, finds himself in the middle of an armed robbery and is shot and killed.
 * Good Times, James Evans, Mississippi. For a comedy titled "Good Times", Diabolus sure was busy depriving the Evanses from having any...
 * Executive Meddling. The show was originally created to combat stereotypes about African-American families. The Evans started as a solidly middle class, two parent household. Unfortunately, the suits felt this wasn't realistic, so James died, and the Evans ended up becoming a poor and struggling single-mother led family.
 * Doctor Who season finales tend to be based on unfortunate circumstances plunging the state of the world from bad to worse.
 * The ending to the 2010 episode "Cold Blood". They've stopped the bad guys, got the humans and the Silurians at least on the right track to start living together in a thousand years, and are all set to escape when a crack in the space-time continuum appears, leading to not only the death of
 * The last of the 2009 specials, "The End of Time", involves a prophecy that the Doctor is soon to die. It concludes with the Doctor You can almost hear the writers straining to make this into a situation that requires the Doctor to sacrifice himself.
 * Prison Break did this in the episode "Selfless" - Scylla had been stolen, everyone was free to go, the release papers had been handed over, and then
 * Supernatural
 * "Playthings". Sam wants his turn at being a martyr and, after getting drunk, forces a promise out of Dean that he would kill him when/if he turns evil. He's hung over the next day and we and Dean think he doesn't remember. But at the end of the episode, he brings it up again and they drive off in an uncomfortable silence. Add it on to them not exactly saving the day either and you've got one hell of a Downer Ending.
 * The Season One finale: John's been possessed and shot, Dean's been tortured, but everyone is alive and Sam is driving them to the hospital, and it looks like everything will be fine. Until a huge truck slams into the Impala, totaling the car, and the episode ends with all three men bloody and unconscious.
 * "Mystery Spot" has this trope happen, but.
 * By way of Crack Defeat, an example where the demon is revealed after the fact: One of The Torkelsons has made it to the final of a contest whose winner will get to be a foreign exchange student in Paris. After her final interview she comes out and announces that she lost. No biggie, so? Well, she recounts her interview and ends with saying that she got the highest score. Why did she lose then? Because the exchange student deal is a homestay (we already knew this), and the French family involved would like a boy (but not this). Well, ISTR that would have made the final interviews meaningless, because there was only one boy amongst the three finalists.
 * The Law and Order franchise loves using this trope to turn a slam-dunk case into an hour-long question of "Will they get away with it". Several Egregious examples:
 * "Marathon" (Law and Order S10E6): Briscoe and Green catch a young Latino thug fresh from mugging and shooting a white housewife. Lenny hears the guy admit it. His word against the perp's. They find physical evidence linking him to the shooting. It gets tossed one piece at a time. When they finally corner him in the end, he Karma Houdinis his way out by dropping the dime on a notorious serial rapist, cutting himself a sweet deal in the process. (McCoy gets him to admit what he said to Lenny: "I gave that white bitch what she deserved")
 * "Suicide Box" (S13E16): A young black male shoots a cop outside of a diner, out of anger that his brother's murder had been swept under the rug. They had him dead to rights... then the mitigating factors rolled in: His brother's death had been ruled a suicide, the man who shot him never denied it (by the cops never looked at him). His and his mother's protests were brushed aside by the cops. And, oh yeah, his brother's body? Gone. The funeral home buried a casket full of trash (an ongoing fraud scheme, it turned out).
 * "Screwed" (SVU S8E22): The episode features the trial of Tutuola's stepson, Darius (crimes committed in the earlier episode, Venom (S7E18)). Except that ALL the evidence except his confession had been thrown out due to questions about Fin's credibility, also Darius (well played by rapper Ludacris) was only going to trial to hurt and embarrass his mother, Fin's ex (who denied him for most of his life). When Fin's ex got on the stand, Darius (acting as his own council) forced her into dropping her own pain-filled bombshell: Darius was a child of rape... by her father. Acquitted of the murders, in the end, Darius can't even take joy in beating the rap and rubbing Fin and his mother's nose in it.
 * "Hell" (SVU S10E14) This episode has the SVU team tracking down a member of an African terrorist organization who tried to murder a young girl. With the help of Elijah, who turns out to have been forced to be a Child Soldier in the same organization, and harbors massive guilt over what he was forced to do, they track down the culprit and arrest him. Everything looks like it'll end well...until the Smug Snake immigration officer reveals that Elijah didn't escape the terrorist organization until after he turned 18, which means he can be legally held responsible for the crimes he was forced to commit. It doesn't end well.
 * "Damaged" (S8E22) Three unrepentant teenage boys are on trial for raping a mentally retarded classmate. After a hard fought trial, the jury returns guilty. Everyone's happy. Not so fast. The judge sets aside the verdict, issues a directed verdict of not guilty saying the prosecution didn't prove its case, and piles on saying the retarded girl knew what she was doing and had "the time of her life." Add in a subplot in which and this episode winds up wrist-slashingly hurtful.
 * "Cold" (SVU S9E19): It looks like the Complete Monster Dirty Cop is about to get convicted, but then, out of nowhere, two bombshells are dropped one after another. The key witness against him? Its revealed that she's an illegal immigrant, rendering her testimony moot. And the autopsy reports that were the key evidence? They couldn't prove the cop raped one of the victims, Novak knew it, and lied about.
 * This Diabolus was essentially just an excuse for Diane Neal and Adam Beach to leave the show, as Novak is disbarred for falsifying the evidence and Lake.
 * "Redemption" (SVU S3E6): The real culprit behind the serial rapes has been caught and all that remains to get the innocent man originally convicted for the crimes out of jail is to get the perp to confess. Everything seems to be smooth sailing... until Elliot goes to the bathroom. When he returns, he finds that in that tiny window of time . Because they can't get a statement from the real perp now, the innocent man stays in jail (it should be noted that the justice system doesn't actually work like this).
 * "Zoontic"(CI). The creepy doctor that had been infecting people with diseases and the sleazeball he hired to rape his old girlfriends are behind bars without a trial. Everything is going swimmingly. And then at the literal last minute, it's revealed that the doctor got 5 grams of anthrax from South America, and he only had 3 grams in his apartment.
 * Of course, sometimes the same person will show up a few seasons later where they actually will get what's coming to them.
 * In the second season of Highlander the Series, Duncan Macleod successfully rescued his mortal girlfriend Tessa from a kidnapper ... only for her to be shot dead by a random mugger less than three minutes after the escape.
 * Although this is generally what's always happening to Edmund Blackadder, one of the few times this happened with everyone is the end of the second series when.
 * Well, this was foreshadowed earlier in the show, what with, and the creators not assuming that Viewers are Morons.
 * Twenty Four season finales used to be made of this trope:
 * Day One: The Drazens are all dead, Senator Palmer is safe, as is Jack Bauer's daughter Kim, and the real mole inside CTU has been caught...but then Jack goes into the CTU server room and finds that.
 * Day Two: The nuclear disaster has long since been averted, the terrorists' mastermind, while not dead or captured, has been sufficiently scared out of the US, and everything appears to be safe once again... until now-President Palmer makes a public appearance and shakes hands with a random "civilian".
 * Day Five: the conspiracy has been exposed, President Logan is arrested and everything seems fine and dandy,
 * Dawsons Creek: in the grand finale, It was well done, though.
 * This was used in one of the season finales for Alias. The Big Bad of the season is temporarily defeated, Sydney and Vaughn finally get to drive off into the sunset together... only for Vaughn to tell Sydney "I'm not who you think I am," and a semi to come out of absolutely nowhere, slamming into their car and ending the season.
 * The Season 5 Finale for House:
 * An episode of CSI involves a drunk-driving car accident and the death of the only survivor while in the hospital. The killer turns out to be the mother of the (underage) daughter killed in the accident, and thought that the other (legal) girl deserved to die as well. So she suffocated the bed-ridden, just-out-of-an-accident, just-coming-out-of-the-coma girl with a plastic bag from the gift shop. Right before the credits?... find out that, because they switched IDs if they got pulled over for driving, got misidentified at the crash site, was so cut, bruised, and bloodied that no one made the connection, the mother suffocated her own daughter, out of spite.
 * Another one has a man returning from a war seeing his wife and newborn and even holding said newborn only to be gunned down by some random intoxicated guy.
 * One of the last few episodes of Monk, Monk spends the episode trying to get on the good side of the kid of the only cop against his reinstatement. Then he gets cornered by a bear, . The writers Yanking The Shaggy Dog's Chain resulted in a mildly delusional Heroic BSOD.
 * The final episode of Series 3 of Primeval where humanity has been saved from evil Helen by a hungry raptor. However the Pliocene anomaly closes, trapping Danny 3 million years in the past.
 * Col. Henry Blake was already written out of Mash. He'd gotten his discharge and left for home. But that wasn't enough, so at the end of his farewell episode, Radar gets the message that his plane was shot down. "There were no survivors."
 * ''Bones has the episode "The Bones on the Blue Line".
 * Some people actually have been screwed over by unexpected twists in Reality TV shows, this may qualify.
 * Shi-Ann in Survivor: Thailand tried to network with the other tribes when time came for the merge, only for instead, they're told they're living on the same beach... so when Shi-Ann's tribe loses, she's low man on the totem pole, so bye-bye Shi-Ann.
 * Savage in Survivor: Pearl Islands, who was pretty much screwed beacuse Lillian was brought back into the game and flipped at the merge, causing him to be voted out.
 * Michelle in Survivor: Fiji. Ten players in the game, and they're divided into two teams of five. Unfortuantely, Michelle's stuck with indifferent players and people on an alliance; not wanting to vote out their own alliance member, they gang up on Michelle, who was playing perfectly well...
 * In the 11th season of the American Big Brother, Jessie was screwed with a sudden twist. The Coup de Tat, which would be awarded to the fan favourite, was given to Jeff. Jeff wisely uses this and puts up Jessie and Natalie. Jessie is voted out, partly by the perceptive Kevin who knew Jessie was in control of the game at that point and that it'd advance him further if he got Jessie out. Jessie was actually quite humble about it. He was actually complimenting Jeff on his brilliant use of the twist, and saying that, had Jeff made the final two, he would gladly cast a vote for him.
 * In the 9th season of Big Brother, when James was voted out, a twist was played to bring either James or Alex (Evicted several weeks prior) back into the house. He was voted back in, and immediately went on a rampage to find out who did not vote him back into the house, and he targeted Matt, who was sent to the Jury House.
 * For that matter, Parker and Alex. They weren't disliked as much as their partners, but because everyone had to play in groups, they merely voted out the one person they disliked the most.
 * Happens in The Amazing Race occasionally as well. In the fifth season finale, what the audience doesn't find out is that Colin and Christie would've caught up to the leading team, and possibly finished first, but their taxi got a flat tire. In several other seasons (seven and seventeen in particular), despite traveling around the world, it's a language barrier in a large American city (thanks to taxi drivers who come from non-English-speaking backgrounds) that ends up hurting teams the most.
 * The Syfy adaptation of the short story "The Cold Equations" ends on this. The basic premise of the story is that a young girl has stowed away on a spaceship carrying urgently needed medical supplies to a distant colony - and, because of her added mass, there isn't enough fuel to land the ship without crashing (and killing everyone on board), so, according to regulations, the pilot is supposed to throw the girl out the airlock so the cargo can arrive safely. It's established fairly early on that the cargo weighs about the same as the girl, and that jettisoning either the cargo or the girl would save the ship. Near the end, the two of them discover that the cargo wasn't what they thought it was, and jettison it, so they're safe now. That's when Diabolus shows up. To the surprise of the pilot and audience, the ship still has too much mass, because they waited too long and are now closer to the planet. So Someone Has to Die anyway.
 * The Series One finale of Sherlock has
 * While not the end of the series (although it could have served as such if the writers strike had not been resolved), season 4.1 finale "Revelations" of the reimagined Battlestar Galactica is a major Wham! Episode that also pulls this trope. Hard. (And things get worse before they get better.)
 * The sixth-season Degrassi the Next Generation episode "Rock This Town" involves many of the main characters attending a birthday party for their friend Liberty. It soon gets out of control when a group of kids from another school show up, but it turns out to be fairly harmless, and everyone has a number of embarrassing moments...until the very end, where Diabolus strikes its head by having one of the main cast (J.T.) stabbed out of the blue by a guest character who never appeared in any episode before or after the one in question.
 * In The Walking Dead, Rick and Glenn spread walker blood all over some raincoats and wear them to blend in with them. Just when you think their safe, an absolutely random rainstorm shows up, stays just long enough to dull the smell from the blood by washing it away, and it stops raining after the zombies have noticed they're not undead.
 * Several episodes of I Shouldn't Be Alive can come off as this. The people who the stories are about almost seem to have been cursed by some malevolent deity based on their awful luck. One episode had a man who had been stranded in a raft for weeks and had to drift from Africa to the Caribbean. He had just reached Caribbean waters, took good supplies, figured everything out and seemed pretty much set to make it all the way to one of the islands safely, when he went to spear a fish with his harpoon, his harpoon snapped in half, the fish did a barrel roll, punctured his raft, and swam away, leaving him to just barely patch his raft up.
 * Xena: Warrior Princess: The overall finale has Xena execute an ambitiously dangerous plan involving her being killed, so she could go off and fight the spirit Big Bad in the spirit world. She sets Gabrielle the task of bringing her back afterwards using her ashes, and magic spring water. It's not until Xena's actually won, and Gabs (and by extension the audience) is all ready for that happy ending, that Xena drops the bombshell, that The twist is not hinted at before it happens, is a disproportionate response, and is largely unnecessary since she mostly seems to have a massive Guilt Complex about the original precipitating incident, which was pretty much an accident. Since Xena claims she knew beforehand, she comes across as something of a Jerkass for not pre-warning Gabs about it.
 * Remedied in the "director's cut" version of the episode, which provides foreshadowing (though still a little too close to the end) and shows us that Xena didn't really know beforehand that she
 * In the second season of Robin Hood every single thing that can go wrong, does go wrong in order to kill off Maid Marian. Marian acts wildly Out of Character. Robin and the other outlaws are inexplicably missing at a crucial moment. No one bothers to give Marian a weapon to defend herself with. Every single one of Guy's Berserk Buttons are pressed. The Idiot Ball is thrown about with such abandon that it leaves Plot Holes in the scenery. The contrived sequence of events unfold with the sole purpose of forcing Guy and Marian into the "right" frame of mind that lead to her murder. (And it still doesn't make any sense).
 * This is the driving force behind the plot, and the source of much of the humor, in Curb Your Enthusiasm.
 * Star Trek: Deep Space Nine: In "Duet," Aamin Maritza pretends to be Gul Darhe'el so that a war crimes trial can be put on and Cardassia can admit to the atrocities it committed. Kira decides to try and end the cycle of violence between Bajorans and Cardassians by letting him go, and telling everyone that he's actually Maritza, an innocent man, and won't be executed for crimes he did not commit. Everything seems to be wrapping up, as Maritza realizes that he can work with the Bajorans to try to atone for the past in a different way. However, a Bajoran drunk who we hadn't seen since the beginning of the episode comes up behind him and stabs him in the back, killing him - not because he was Darhe'el, but simply because he was a Cardassian.
 * In Secret Love, Yoo-jung's father just happens to wander off without informing her on the day she is due to have a court hearing, also leaving his phone in the shop so she can't simply call him. She forgets about the hearing in her panicked search, an arrest warrant is put out for the unintended absence, and everything goes downhill from there.

Music

 * Depeche Mode's song "Blasphemous Rumors" is about a girl who tried to commit suicide at age sixteen. She fails, and learns to love life again. Then she dies in an accident.
 * Countless country songs take advantage of this, often to a narmy extent. In fact, it's a common joke in the American south that if you play country music backwards, the singer's wife will return to him, bearing his dog and his intact truck.

Newspaper Comics

 * In Funky Winkerbean, Wally (nephew of the title character) had just returned from a return trip to Iraq, with his new bride and newly adopted orphaned waif in tow. The future looked bright for the young Winkerbeans... until Wally got a letter from the Army telling him that he was technically A.W.O.L., because his discharge was issued one day too early. As a result, Wally was ordered back to active duty to serve a full year's tour of duty. The readership was pretty sure that discharges don't work like that (even the ones incorrectly filed) and could've fought the order if he wanted (and almost certainly won). But he fought the war instead. As an extra kick in the metaphorical nads, Becky finds out she's pregnant just in time for Wally to get shipped off. An extra EXTRA kick was administered when the second Time Skip came about and Wally was nowhere to be found. Turns out that for the entire second Time Skip, Wally was held captive by insurgents (which, frankly, could merit its own Did Not Do the Research entry).
 * Which is of course nonsense. Your term of service is what are you obligated to serve unless excused. The government can discharge you from military service at any time it wants, for any reason it wants, and shazam, you are legally discharged. They just usually won't because they went to all the trouble of training you, so are they going to get their full use out of you. But if they fill out your discharge papers one day early, sign them, stamp them, and put them into effect... that simply means that you have been excused from one day's worth of military service. Pack your seabag and go home.
 * Ironically, the author's complete ignorance on military discharges was such that he overlooked an entirely legal way to suddenly recall Wally to service. All initial enlistment contracts are for eight years of service obligation, not four. The typical arrangement is only four years of active duty and then four more years of 'Individual Ready Reserve' status, the practical upshot being that short of medical disability, Bad Conduct Discharge, etc., you can be yanked back in entirely at their discretion up until eight years have passed since your initial enlistment. The recruiter is required to make durn sure you understand this before you sign.
 * Peanuts: If you're going into the funny pages, Charlie Brown learned that the demon of heartbreaking sports losses can attack after the end of the game, when he had a rare win stripped from him over a "gambling scandal" (Rerun betting Snoopy a nickel that they would win). Can they do that? No, seriously, can they?
 * Curtis: * GULP!* It's Derrick and "Onion"!

Professional Wrestling

 * The Montreal Screwjob arguably qualifies as this.
 * The real life circumstances surrounding Owen Hart's death.
 * Eddie Guerrero had a huge drug problem early in his career but got over it through religion. After being a Heel most of his career and having just made a Heel Face Turn, having gained Batista's trust after his refusal to cheat as he normally does costs him the match and on his way to fight a match where he was scheduled to win the championship title was found dead in his hotel room days before his pay-per-view. Dead from the effects of the drugs he hadn't been using for years. Don't do drugs, even if you quit they will catch up with you.
 * Michael Cole winning at Wrestlemania XXVII.
 * Let's face it; any time someone particularly favored by (or disliked by) a heel GM or VP is involved in a match (or worse, said GM or VP is in the match) you can pretty much guarantee this will happen, either in the form of changing the rules mid-match or outright overturning results for nothing more than spite.

Tabletop Games

 * To some BattleTech fans, Diabolus is behind the Jihad storyline. Let's see, the Clan invasion is finally called off, the Star League tentatively reestablished, and while there are still loose ends left over (like the threat of the Wolf Khan to come invading anyway once the original truce is up, or the aftermath of a nasty civil war) things finally seem to be ready to calm down a bit...but hey, we can't have that, right? This game isn't called PeaceTech! So the Star League declares itself a sham and disbands again for no good reason just in time to cause the suddenly uber-powerful pseudo-religious lunatics known as the Word of Blake to go Ax Crazy and start pulling cyborg super soldiers, nuclear weapons, and other stuff out of their nether regions in an all-out war against everybody...
 * The ending to the Deadlands: Hell on Earth setting involved the PCs getting a chance to kill the Big Bads of the game. After going through a bunch of Rail Roaded scenes, they're presented with the opportunity to win and a ship to do so . Then you get to a distant planet... and the ship crashes and the Big Bads are re-released. At least the Game Master should have been implying that this was the best possible result from the start; the can that had the Big Bads in it was always shaky at best. Guess who gets to hunt them down and finish the job now?
 * The entire universe of Warhammer 40,000 was probably made by Diabolus.

Toys

 * Bionicle has this- in the most literal way possible. At the end of the 2008 arc, the heroes have Outrun the Fireball, awoken the Great Spirit, defeated the villains and are ready to celebrate..

Theatre

 * In the Richard Strauss opera Elektra, the title character, in the midst of rejoicing over the deaths of her mother and her consort, suddenly drops dead at the end for no reason except to bring down the curtain on a crushing downer note.
 * Shakespeare is a notorious offender. For example, in King Lear comes pretty much out of the blue, transforming the play into a tragedy in its final act.
 * King Lear, like many of Shakespeare's other plays, was based on earlier stories that his audience would have been familiar with. and  don't die in those stories. Shakespeare killed them off because he wanted to surprise the audience. This ending was subject to a lot of Fanon Discontinuity in later centuries, and many performances ended with  marrying  instead ... even though she already got married earlier in the play.
 * Romeo and Juliet is one Diabolus Ex Machina after another. This is even lampshaded; the line in the opening speech about them being "star-crossed lovers" is a reference to the practice of trying to predict the future using astrology, implying that Fate really is out to get them.

Video Games
"Ford: ...And you're SURE there's no other way out of here? Prometheus: Well, there was a helicopter..."
 * A lot of the moral choices in the second Army of Two game end this way. You either choose the "bad" option, or you choose the "good" option...except that the guy you gave up some advantage to save turns out to be corrupt AND selling weapons to terrorists. Or a guy you choose to save instead of killing in exchange for money is later killed in a plane crash accident.
 * The updated ending to Portal - The first independently mobile entity apart from Chell turns up just to drag her back right after you thought she was free.
 * In any game where a chopper is called in to rescue your party halfway through the game, it will probably get shot down or otherwise destroyed, as in Resident Evil 3: Nemesis, Dino Crisis, Resident Evil 4, or Call of Duty 4.
 * Left 4 Dead had the infamous Chopper pilot dying at the end of the first campaign. It was nixed when many people found the ending too depressing and cheated out of their feeling of accomplishment. Ironically it was the fan backlash that caused Valve to create a filler campaign between No Mercy and Death Toll, reinstating what was taken out. They use this again in the sequel, to link all of the campaigns together. This meant that some sort of Diabolus Ex Machina would show up in the beginning of each campaign, serving as the Machina of the last campaign (this included a chopper pilot dying as well).
 * In Serious Sam 3, after seeing at least two choppers get shot down, (one of which he was ON at the time), Sam decides he's not going to get on any more choppers.
 * The Conduit actually jokes about it, where Ford's way off an oil rig is supposedly a Leviathan. The Leviathan destroys a helicopter flying over the base:

"Player Character: I remember being disappointed that the fortress's structure wasn't more architecturally sound. Ammon Jerro: Yes. That powerful and evil beings insist on causing destruction even as the die is an unfortunate habit."
 * The path towards the fourth ending in Drakengard is shaping up to be a Bittersweet Ending, which, given the only other "good" ending is also bittersweet, doesn't seem too bad. After all, after finding out that the Creepy Child Big Bad is irredeemably evil even after the protests of her twin brother, the heroes have finally succeeded in killing her once and for all. Now the world is saved. Except, wait, something's falling out of the sky...
 * Justified in that said Creepy Child was essentially the avatar or representative of said things falling out of the sky. We probably should mention that said things are pissed off as hell after she dies and with no seal holding them back...well...
 * The real kicker is the fifth ending. The heroes cross over into another dimension to kill the mother of all the aforementioned elderitch abominations. She and the heroes are transported to modern day Tokyo and, after a climatic boss battle, get shot down by missiles from an aircraft. Wow...
 * And then NieR happens.
 * Apocalypse: Bruce Willis/Trey Kincaid has defeated the four horsemen, (i.e. the Dragons), and is about to take down the Big Bad Reverend. Unfortunately, he gets a Demonic Possession ex machina. Downer Ending. Or maybe intended to be a Cliff Hanger leading to a Vaporware sequel?
 * Raiden's ending in the original Mortal Kombat. Evil vanquished: check. BBEG dead: check. Hey fellas; let's break the world ourselves!
 * And Reptile's ending in Mortal Kombat 4. Go through the entire game, win the tournament, and then your Bad Boss pops your head like a grape for asking for a reward. WTF?
 * Reptile's ending is always a Diabolus ex Machina. The one time that he actually has a happy ending is in Armageddon.
 * Mortal Kombat 9 just slams into this wall at Mach 5. After Nightwolf regroups with Raiden's chosen right as Raiden and Liu Kang go to have a chat with the Elder Gods. Then,  Remember that scene three chapters back in Stryker's chapter when  Afterward, the game switches over to Raiden for the final chapter, having him deal with the tragic repercussions of this event...
 * Half-Life 2 Episode 2: After Gordon has whipped the Striders,, leaving the game, instead of a happy ending, on a Kick the Dog moment.
 * Heck, look at Half-Life,
 * F.E.A.R. ends with the protagonist being extracted aboard a helicopter with a couple of NPC teammates. The helicopter suddenly lurches and Alma is seen climbing aboard an instant before the game cuts to the credits. Which are worth sitting through for yet another whammy.
 * The Expansion Pack Extraction Point, takes this trope one step further Ironically,
 * Basically any time your less-than-useless Delta Force escorts come to extract you/insert you they all get killed horribly before the fighting even begins.
 * Halfway through Call of Duty 4, after you've completed the primary objective in Shock and Awe, there's a Diabolic Nuke Ex Machina, when you get a call that the bad guys have set up a nuke in Asaad's palace, then one of your fellow chopper pilots gets shot down. You land to rescue her, but it's already too late, and the nuke knocks the escaping helicopters out of the sky and kills all of the American main characters. You have a minute of Controllable Helplessness before the protagonist, too, expires from radiation poisoning. As a result, the shaggy dog has not just been shot, but totally annihilated.
 * And during the final mission, after stopping the nuke launch, an invincible Hind gunship appears and lays waste to your squad. Then the Big Bad starts executing the survivors, but before he can get to you, in a semi-Deus Ex Machina, the Russian Loyalists arrive and destroy the Hind, distracting the Big Bad and allowing your CO to pass you a pistol. It isn't until the next game that you find out whether either of you survived.
 * The fake-surrendering Japanese soldiers who kill Roebuck/Polonsky at the end of "Breaking Point" in World At War could qualify, too, seeing as the mission had been a success up to that point, and Roebuck even said in the opening narration that they would all go home at the end. Even worse, you have to choose which one to save. In about a split instant.
 * But that one's kinda okay, considering one choice leads to your group essentially being led by Jack Bauer.
 * Not quite the ending, but the climax of World 1 in Final Fantasy V is rather like this. Against all odds, you finally managed to get to the last elemental crystal in time, unlike all the other ones that ended up breaking. The bad guy's possessed puppet gets beaten back, there's a lovely reunion with one of the characters and his granddaughter, where he gets his memory of her back, and a reunion of two of the characters and their long-lost father... and then the crystal shatters anyway, because if the Big Bad stayed imprisoned by its power there'd be no other 2/3s of the game.
 * Disc 2 of Final Fantasy VII is a Diabolus Ex Machina strewn throughout an entire disc. Aside from, The party chases Sephiroth to the Northern Crater, where they prepare to battle him once and for all, So now, not only is Meteor looming, about to kill the world in one week, but the Planet has released its failsafe, a group of massive biomechanical creatures called the WEAPONs that are capable of wreaking serious destruction. So these monsters are on the rampage, the apocalypse is coming in a week, and the crew is slated for public execution. And the next time we see Cloud?  Wow...
 * TimeShift. You've killed the Big Bad, retrieved the only remaining temporal jump drive in your particular dimension, taken down a planet-wide fascist government, and even saved the girl.
 * Parodied in I Wanna Be the Guy. At the end of it, you defeat The Guy, take his gun, and return home triumphantly as the credits roll. You also walk under a tree with one of the game's deadly apples giant cherries on it, which falls. If you're not expecting it and don't move, it lands on you, killing you and giving you the standard Game Over screen even though it's after the credits. Fortunately the game still counts you as having beaten it.
 * SOMETIMES!
 * Neverwinter Nights 2 has one of the most appalling Diabolus Ex Machina endings ever. Quite literally, Rocks Fall, Everyone Dies.
 * Remedied in the Expansion Pack that follows with you waking up afterward, albeit on the opposite side of Faerun, and you spend much of the game trying to figure out how the hell you got there.
 * The rocks falling is lampshaded later in Mask of the Betrayer by Ammon Jerro, in a rather hypocritical bit of humor.

"Assessment: Don Corneo's secret weapon, a monster in the form of a house. No one knows how it was built."
 * Fallout 3 is especially guilty of this, capping a brilliant game with a totally illogical ending that forces the player to
 * Due to gamer outcry at this being one of the dumbest endings in gaming history, one of the expansion packs, specifically Broken Steel, changes this ending, allowing you
 * At the end of Marathon 2, the defeated Pfhor use their sun-shattering Trih Xeem on L'howon's sun, releasing the omnicidal Eldritch Abomination known as the W'rkncacnter.
 * The Baldur's Gate series has a variety of endings, depending on your action in-game. One of them involves the Protagonist giving up their divine soul and turning their back on Godhood in order to be with their newly-found True Love - who, in her aftermath/autobiography is brutally murdered by her vengeful kin, leaving the Protagonist to raise their child alone, embittered, and hell-bent on committing genocide as return. This even applies if the Protagonist was, for the previous 100 hours of gameplay, a Lawful Good Priest of Peace and Healing...
 * It's put as a rumour, so you can basically decide whether your character would have done that or not.
 * The ending to Infocom's text adventure Infidel has always been somewhat controversial with fans because it's a good example of this trope being used to Shoot the Shaggy Dog. The protagonist (despite being selfish, greedy, and foolish) makes it to the pyramid's burial chamber to claim the riches ... . And this, after solving a bunch of very difficult puzzles (including a few 'learn by dying' puzzles).
 * As retconned in the intro to Turok 3, the destruction of Primagen in Turok 2 caused a explosion that destroyed the entire universe, which is what Joshua was trying to prevent in the first place, making that game somewhat of a Shoot the Shaggy Dog. Fortunately, the universe is recreated, and Joshua somehow survives and has offspring, only to be killed at the beginning of the third game.
 * Near the end of Fable II
 * Private Jammy is a soldier stationed at Fort Mourningwood in Fable III, named such for his good luck (he's been wounded a whopping total of 724 times).
 * Free Space 2 does this with a flourish: at the end of an arduous, complicated and desperate campaign to destroy the Shivan dreadnought Sathanas which threatens the (known) galaxy, you learn that the Shivans have about a bazillion more such ships.
 * Jak X. Non-fatal example, but after you've won the game,
 * This almost hit Lamia Loveless as part of a plot just to see Kyosuke Nanbu getting Emo, but she got better eventually. Either her recovery was part of Banpresto's plan all along, or as a reaction of fans outraging at the Diabolus Ex Machina that they set on her just because her default story is done and they want to put some dark and edgy feel on OG.
 * You just wiped all the gangs out of Paragon City and finished Crackdown..
 * In Saints Row, under gang leader Julius, you destroy the three rival gangs in Stillwater and "unify" the city under the Third Street Saints.
 * In the sequel, it's revealed that
 * It's also revealed in the sequel that
 * In the Diablo series, this basically explains the sequels, given the numerous ways in which the titular antagonist is apparently Killed Off for Real. But then, one must look at the Meaningful Name of the series...
 * To be more exact, the first game ends with you killing the Big Bad, Diablo and ramming his soulstone into your own head so you can contain him with your mind. It did not work so well. In fact, Diablo possessed the hero and used his power to strengthen himself so he could escape the dungeon and revive the other Prime Evils. The second game ends with you killing the last of the three Prime Evils, Baal, just after he corrupted the Worldstone, the thing that keeps the demons out of the world (not that it was doing a good job). Archangel Tyrael goes for the lesser of two evils and destroys the corrupted Worldstone. The one you've fought so hard over to protect. And for Diablo 3, Blizzard has revealed that the destruction of the Worldstone also blew up the entire mountain, destroyed the barbarian capital and turned the continent into a nuclear wasteland. By the way, the Worldstone not only kept the demons out but also the angels because some of them view humanity as a taint on creation and are quite eager to destroy it. Instead of just the Prime Evils raising an army, a full scale demonic AND angelic invasion involving pretty much every character from either side with a name is about to occur. But hey, congratulations, you won the game.
 * Oh, and you know how all the player characters of the first game either went insane and / or were possessed in the second? Prepare to be not surprised at the ultimate fate of most of the heroes of Diablo II, or that the three Big Bads were in fact manipulating you all along to do their bidding.
 * The World Ends With You: After surviving the Reaper's Game, Neku and Shiki discover that Neku is fine with this, until the Conductor hits him with the whammy that
 * Not Quite!
 * Charlie, who always dies in his endings due to Foregone Conclusion, manages to corner Bison in Street Fighter Alpha 2, only to be shot on the back by his intended back-up chopper.
 * Oichi in Sengoku Basara dies this way in her own story. On the other hand, the anime version of Sengoku Basara... well, puts this on many many characters..
 * Quick summary of diabolus in Ever 17: Hurray! Everyone else already escaped and we've loads of time to get out plus a submarine! They get out safely, chatting while they go up and But it gets better.
 * In the ending of Star Wars: Republic Commando, your squad has taken out a massive separatist gunship and are ready for evac. Then, out of nowhere (and offscreen), Sev reports he's under attack and you lose contact with him. Despite the protests of you and your squad, your commander refuses to let you rescue him, and you all get on your evac shuttle, leaving him to die. A lot of players hated Yoda for that.
 * Ameena's subplot in Star Ocean: Till the End of Time ends on a big one. Ameena, Ill Girl and blatant Expy of another flower girl, ends up being reunited with her childhood friend. Thenarty chases Sephiroth to the Noro'' (he was injured in battle a few scenes prior to this). It's even more of a nightmare for the protagonist, since the girl was also virtually identical to his own best friend.

 * World of Warcraft, the Pit of Saron: when Scourgelord Tyrannus is defeated, the freed slaves run onto his overlook en masse, celebrating. Suddenly, Sindragosa appears and blows nearly everyone to smithereens, the players themselves saved by Sylvanas/Jaina's teleport.
 * Aquaria pulls this in The Stinger:  This was supposed to be a Sequel Hook, which would have been annoying but okay in the end. But now comes word that the dev team has splintered and moved on to other projects- including one hyped as a Spiritual Successor. Nice Job Ruining A Perfectly Good Ending, Bit Blot.
 * The creator has admitted in this message board thread that there were never any fixed plans for a sequel, and that he wanted to avoid a happy ending, possibly making this an intentional example after all.
 * In Killzone 2, the ISA has busted their asses to get to and defeat Visari, only to find out that the Helghast have a huge reserve fleet coming.
 * In The Stinger of Syphon Filter: Logan's Shadow, Logan and Xing return to their hideout only to find Mujari dead and Teresa wounded by Trinidad, who then shoots Logan in a moment of Cutscene Incompetence, although he gets off a Last Breath Bullet. Xing starts CPR on Logan, and the story is left on a Cliff Hanger (which will never be resolved).
 * This spans two games in The Elder Scrolls - in Morrowind, the Nerevarine destroys the Heart of Lorkhan, freeing Vvardenfell from the Blight and Dagoth Ur. In Oblivion, it is revealed that since Vvardenfell's resident living god also relied on the Heart, the Ministry of Truth fell, destroyed Vivec City, and triggered the eruption of Red Mountain, resulting in the province of Morrowind no longer existing.
 * Dragon Age II: the Hawke family farm is gone, one of your new allies is dying of darkspawn taint, and just when you think it's safe to stop for a breather, an ogre comes out of nowhere to brutally smash one of your siblings into the dirt, reducing your party to you, your other sibling, and Aveline against the ogre and its hurlock buddies.
 * No, those aren't dramatic spoilers; that is the ''prelude to the game, which mostly consists of the player trying to build his/herself and the family back up from less-than-nothing.
 * The actual game will then go on to torment the remaining Hawke family far worse.
 * Metroid: Zero Mission is a remake of the original Metroid that continues after the original ended. It accomplishes this by.

 * Quite a few Bad Ends for Ookamikakushi fall under this. To be fair, not all of them are like this; some can be obtained by simply making the wrong decision (such as choosing to believe one girl over the other). As for others, however, there are arcs where you don't immediatley see the result of a combination of choices you made until much later, which tend to result in this trope.
 * Probably the best example of this is one Bad End where Hiroshi attempts to commit suicide after only to be saved by Nemuru, who convinces him to keep living. Sounds like a happy, potentially heartwarming way to end a chapter, right?
 * In Zenonia 4, Regret spends most of the game trying to Set Right What Once Went Wrong with Time Travel. Every time he changes the past, something else happens to ensure that the world is still doomed. Regret eventually decides to face the threat head on rather than running back to the past in a futile attempt to avoid it.
 * Mass Effect 3's ending. . However, no matter how the Crucible is used,.

 * Season 5 of Survivor Fan Characters was full of these, given that the season was tagged "The Cursed Islands". Such "curses" involved having someone divvy up the tribes, but then get sent to Exile Island and have no control over which tribe they're sent to at the end of Day 3; a tribe being absorbed into the other tribes; someone having the choice to send themselves to Exile Island until the merge, but have absolutely no contact with their tribe mates until then; a random mutiny - one of the challenges was full of these; mainly, contestants would vote as to how many tribal councils they would be willing to go to with such debilitations as not being able to vote, having an extra vote against them, and not being applicable to win immunity.

 * In Sims Big Brother 5, the main twist of the season was that there was a liar in the house. By "liar", I mean someone playing under a false identity. The Liar was revealed to be Logan, but not to the houseguests. One week, there was a double elimination week and Michael Goldsmith said they had to evict the Liar, or else they would lose a portion of the grand prize. (Which the Liar would receive) Knowing he was in trouble from the other alliance, Logan persuaded the majority and the floaters that the liar was Darby. Thus, the house cast their votes for Darby and Logan, and since Darby received more, she was evicted.
 * Diablous ex Machina struck once before. In Sims Big Brother 2, there was a week in which 6 people were taken into the Solitary chamber, making themselves immune from the vote during Public Voting Week (in which everyone was up on the block, sans the 6 in the chamber). However, the person who lost all of the challenges was more or less screwed. They couldn't use any of the luxuries, couldn't compete for Head of household, were automatically nominated for three weeks in a row, had to eat an instant meal diet, and if any of those rules were broken, they'd be expelled. Dora unfortunately lost....meaning she had many of the worst weeks of her life in the house. Is it any wonder that after becoming the Unlucky Houseguest, she asked everyone to nominate her and vote her out?
 * Parodied in The Nostalgia Critic's review of Moulin Rouge: he spent practically the entire review complaining about the movie before the The Nostalgia Chick and Brental Floss convinced him it was fine as a guilty pleasure. But this being a review of Moulin Rouge, it needed to end tragically, so he randomly shot Brental Floss and mourned his loss.
 * Of course, this was mocking one of their complaints about the movie, namely that Satine's consumption—and her decision to break up with Christian instead of telling him about it—seem like this trope.
 * Though the fact that it's basically a retelling of La Traviata only with the entire last act and a half condensed into 3 minutes has a fair bit to do with that.

 * Even the kid-friendly world of Alvin and The Chipmunks is not safe from the Diabolus Ex Machina. In one episode, involving a new cat dubbed "Cookie Chomper the 3rd", a Death by Newbery Medal comes out of nowhere in the last two minutes of the show.
 * This trope is played for laughs in Stone Trek: Every episode ends on a happy note... until the Starship Magnetize explodes for no apparent reason.
 * The early episodes of Sealab 2021 also always ended with the Sealab exploding. The most notable example of this trope is the episode that's just an episode of the original Sealab 2020 series, and so it's fairly normal and has a happy ending. Then the Sealab explodes for no reason.
 * It exploded because the captain of the submarine gave such bad directions to his helmsmen, they drove right into Sealab. THEN it exploded.
