Oh Crap/Literature

"[[spoiler:Viper: Say it! (stabs Mountain)
 * In Animorphs, the final book has two great ones in a scene.
 * Probably
 * The Keepers in House of the Scorpion describe their side of the story to Esperanza of Matt and the Lost Boys'
 * While we can't see it, the description of 's death in the climax of The Dragon Reborn leaves very little doubt that he had this kind of reaction. Understandable, since The Chessmaster was moments away from the fulfillment of his Evil Plan before being blindsided by someone he thought he had removed from the equation and promptly rendered Deader Than Dead.
 * 's death was much the same way, if his last words are any indication ("You! NO!").
 * When Semirhage enacts her plot to, Rand gets a huge one. Quickly followed by Semirhage getting her own Oh Crap moment when
 * In Towers of Midnight, the Borderlanders get one so bad that they instantly cross the Despair Event Horizon when they see the Dark One's armies rushing toward them.
 * Harry Turtledove's Worldwar series is basically one big Oh Crap moment for The Race. Oh, it's only been 800 years, how far could the savages have gone since 1142? Wait, is the planet emitting radio waves?
 * Plus, every Lizard viewpoint character has at least one of these.
 * Three such characters, two shiplords and an artillery supervisor, are used for the sole purpose of screaming OH CRAP before the Germans or the Americans kill them.
 * The career of Flight Captain Teerts is a series of these events. First, his jet is shot down behind Japanese lines due to the world's luckiest bullet hitting his engine. Not knowing how the Japanese treat their prisoners, he surrenders. He's hauled over to Tokyo and interrogated on how to build a nuke. He tries to confuse the Japanese scientists by telling them things like "Nukes use hydrogen and plutonium", only to discover that they already knew about fusion reactions. He is eventually rescued, only to nearly die when, finally.
 * The conclusion of the final book, Homeward Bound, is literally one big Oh Crap moment for the entire Race.
 * Vision of the Future, a Star Wars Expanded Universe novel, had a great one, where one of the bad guys, described as a "liar, embezzler, and probable traitor... went white" in shock and fear.
 * Cersei Lannister's response to disagreement from the new High Septon in "A Feast For Crows".
 * And, in A Storm of Swords, the end of the duel between the Red Viper and the Mountain.

Mountain: (grabs Viper and slowly crushes his windpipe) Elia of Dorne! I killed her screaming whelp! Then I raped her! Then I smashed her fucking head in! Like this!

Everyone: Oh shit!]]"

"Legolas: Ai, Ai! A Balrog! A Balrog is come!"
 * The most epic/tragic one is provided by Catelyn Stark in A Storm of Swords
 * In The Lord of the Rings,
 * Saruman has one when
 * Sauron, when Transferred surprisingly well to film (see above).
 * One that didn't make the adaptation:

""Those watching said, later, that when Vorbis looked up, his expression just had time to change before. It was a revelation.""
 * Vordarian in Barrayar probably counts. His last words are, "What? You're a Betan! You can't do--" Except she could. And did.
 * The Vorkosigan Universe likes this. In "A Civil Campaign," Richars Vorruyter is preparing to taunt Miles as Count Vorhalas and the other conservatives arrive to give him a majority of votes, when . Later in the same scene,.
 * For that matter, Miles causes another one of these in The Warrior's Apprentice, where he.
 * In Guards Guards, the first victim of the dragon gets this as a death scene: "He said 'Oh shi--' and died."
 * This being Discworld, he got a chance to finish it, as his ride to the afterlife shows up. "--t."
 * Later in the series, Greebo the cat invokes an identical half-line of dialogue -- the latter when he finishes becoming human, the former when he starts reverting to cat -- when he suffers an involuntary shapechange.
 * OHSHITOHSHITOHSHIT I'M GONNA DI! is Rincewind's catchphrase.
 * Trev Likely has an internal-monologue Oh Crap moment in Unseen Academicals, when he realizes that the wizard who's supposed to use magic to prevent any cheating on the soccer field has just blocked all magic, including his own, from operating there for the duration of the game.
 * It is frequent to hear OH SHIT whenever anyone realizes they've just said Monkey around the Librarian.
 * From Small Gods:

"Oh no, not again."
 * In David Eddings' Enchanter's End Game (5th book of the Belgariad), one can easily imagine Zedar's face when.
 * Earlier in Magician's Gambit Ctuchik, in a moment of desperation, tried to use sorcery to destroy the Orb with the command "Be not!" His terror caused him to forget that was one thing the universe itself would not allow, and he had a single moment to remember before he was not.
 * When Oedipus Rex finally figures it out, making this Older Than Feudalism.
 * Honor Harrington has several, often when some new wrinkle in technology is unleashed. One of the best is from minor recurring character Genevieve Chin, who survived all the way to the final battle in the tenth book, War Of Honor. Her enemies fire multiple-stage missiles that proceed under power for some time, coast ballistically through space for a long time, then fire the second stage and do attack runs. Her initial skepticism -- that these missiles would be easily stopped because the range would prevent their parent ships from relaying targeting data -- was quickly overruled when she remembered that her opponents had recently unveiled a new technology allowing them to control the missiles in real-time from virtually any range. Unfortunately, she was two minutes too late, and Chin and her entire fleet were wiped out in what was probably the biggest massacre of the series.
 * The opening of that battle also contained an Oh Crap moment for Honor herself as she realises that yes, her home IS being invaded by a fleet that is numerically larger than any fleet fielded in recorded history.
 * The probable reaction of the Havenite task force unlucky enough to be in the way of the Grayson Space Navy after Honor, as Fleet Admiral Judah Yanakov was very displeased by this turn of events. As was every soldier under his command. His order? "Lady Harrington, and no mercy!"
 * That command inspired an Oh Crap from Admiral White Haven as well, especially once the crippled Havenite ships began to launch escape pods, because he thought he was about to witness a massive war crime, until he realized that the order was No Mercy, as opposed to No Quarter.
 * The reaction of the leading bureucrats of the Solarian League when they are told that
 * Pavel Young has a rather impressive one in Field of Dishonor when he watches Honor curb stomp duel the professional duelist he'd hired to kill her, followed by Honor's declaration on live HD that he was next.
 * Mission of Honor has the SLN task force under Admiral Sandra Crandall getting a taste of Manticoran missile spam, as well as
 * The very first book, On Basilisk Station, has a very strongly implied one on the part of the RMN's Home Fleet, after Honor signalled "Case Zulu." In RMN communications practice, Case Zulu always is taken to mean
 * This is the near-verbatim response of the Big Bad in charge of the Mesan Alignment in A Rising Thunder on learning that have surpassed Mesa's worst-case scenario. Oh, and it gets better.
 * There's an interesting mix of Oh Crap and lack of Oh Crap moments as the conflict between Manticore and the Solarian League builds in Mission of Honor: various Solarian commanders have Oh Crap moments as they find themselves on the wrong end of increasingly lopsided battles (a group of cruisers and destroyers defeat seven battlecruisers, six battlecruisers defeat twenty battlecruisers, seven heavy cruisers defeat 71 superdreadnaughts), but the Solarian high command remains assured that once they concentrate a sufficient force, Manticore will be crushed like a bug.
 * The climax of Good Omens. "For the second time in 6,000 years, Aziraphale swore."
 * In The League of Peoples Verse novels by James Alan Gardner, the explorer corps (aka "the expendables") are so used to experiencing such moments that "going 'oh shit!'" is a euphemism for dying.
 * Dragonlance: Raistlin Majere, upon seeing Tasslehoff (who, as a kender, can screw up the timestream) in the past, reflects on what this means for his plan to ascend to godhood. Precisely three thoughts later, the reflection is "I might die!"
 * In Island in The Sea of Time, the character Swindapa is captured, brutally raped, and given nasty STDs by her culture's enemies, then given as a present to the Nantucketer admiral, In the climactic battle, . In the same battle,.
 * The Hitchhiker's Guide to the Galaxy: In the immortal words of a bowl of petunias:

"Freddy: Wait! No, you wait -- Stop!"
 * In the book Fool, whenever the fool's plans are derailed (about once a chapter, till in the end when his whole Plan pays off. IN SPADES!) or on the last page when the witches show up to claim their price, which turns out to be Spain, his automatic response is a simple "Fuckstockings."
 * Happens to Freddy twice in the book A Nightmare on Elm Street: The Dream Dealers. The first time, Freddy wakes up after being briefly knocked out and spots a bomb (which kept showing up in dreams) lying next to him, seconds before it explodes. Later on, when Freddy pulls himself back together, he finds himself confronted by the escaped souls of his recent victims, who decided to pay him a little visit before crossing over to the great beyond. Freddy is pretty much left speechless:

"Rufe: "I just wanted to know what a shark looks like."
 * Evil Chancellor Wienis goes through several of these in Foundation.
 * A rare sighting of the invoked "Oh Crap" in Isaac Asimov's Second Foundation. You really don't want to read this if you have not read the book, though. Really.
 * Many of the villains in the Redwall books have Oh Crap moments before their inevitably gruesome deaths.
 * The Bellmaker has one for the heroes;

Finnbar: "Well, mostly all you'll see is a big pointy fin sticking out of the water."

Rufe: "Does it look like this one circling our ship, sir?""

"Harry: (Grinning like a maniac) Wile E. Coyote. Suuuuuper genius."
 * Opal from Artemis Fowl: The Opal Deception. Her master plan, like many, involves a massive bomb. Suddenly, her thugs notice the bomb has gone missing, and receives a taunt from the heroes, who have just snuck into, and out of, her shuttle. However, she still has the detonator and the opposing shuttle is in the right place, so she presses it. Only then does she realize they didn't steal the bomb, just hid it.
 * John Taylor, protagonist of the Nightside series, has cultivated a reputation so nasty that he can often get an Oh Crap reaction from the opposition, simply by introducing himself. A pair of huge demons summoned to attack him once took one look at him, went through simultaneous Oh Crap revelations, and turned round to berate their summoner for pitting them against him.
 * Bit of a subversion, as Taylor is often bluffing.
 * or is he?
 * During the duel between Westley and Inigo in The Princess Bride, this is what you think is going through the mind of Westley after Inigo reveals that he's not left handed, but then Westley gets him right back and reveals that he isn't left handed either! Inigo's reaction is priceless.
 * Subverted in the battle of wits against Vizzini, when
 * In Perdido Street Station, the managers of Cadnebar's, an illegal gladitorial arena, play up the drama for the crowds by deliberately setting up Oh Crap moments for naive yokels, who sign up for what they expect will be an easy two-against-one fight. Too bad they don't know it's two of them against one weaponized killer Remade or professional cactus-man mercenary until their opponent steps onto the field....
 * Also, Simon/Silas gets a doozy of an Oh Crap in The Scar, when he realizes
 * Jim Butcher must love this trope. Practically every single one of his books (both series) features one of these, usually as the main characters realize that the situation, already sucky, just went from worse to "OMFG".
 * Done at least once per book in The Dresden Files. Almost each instance requires multiple books of Info Dump and backstory, plus a few Noodle Incidents thrown in for flavor, to really understand the full power and scope of exactly how screwed Harry is, though.
 * In Turn Coat, Harry manages to induce this in his mentor after casually mentioning that there were more parties about to show up. Only the mentor realized what Harry's plan really was. [=McCoy] takes it fairly well, all things considered.

"I looked at him, shocked. He'd used... grammar."
 * In Changes, the thing that lets Harry know just how bad things are is when he talks to Mac, the usually monosyllabic bartender, at the beginning of the book. Harry's reaction to Mac speaking for a good paragraph is this:

"The Yawning Angel: Two hundred and thirty-two thousand times the speed of light. Dear holy fucking shit."
 * Changes also gets a good one in early, as a Red Court Vampire who's part of a hit crew runs into Harry... and runs screaming in the other direction.
 * In the Codex Alera, this is usually caused by an enormous army appearing out of nowhere. The Vord in particular are so good at causing this that even a fairly small group turned large portions of the second book into a string of such moments as Bernard and company fall into trap after trap.
 * In 1984, this is pretty much how Winston and Julia react when
 * In Harry Potter and the Deathly Hallows this is pretty much 's reaction when of all people kills her. This was also what most fans said when they read the rather memorable Pre-Ass-Kicking One-Liner, accompanied by giggles.
 * Don't forget Harry's reaction in Deathly Hallows, when he . He's just been overwhelmed by images of his mother, revelation's of Snape's character, guilt that he left him to die, not knowing the truth, and now - Harry has to This is a Tear Jerker, Crowning Moment of Awesome, Crowning Moment of Heartwarming AND an Oh Crap moment. That in itself is epic.
 * Also Voldemort's reaction after.
 * In Memory, Sorrow, and Thorn, the protagonists experience a domino-like series of these moments as Binabik's realization that they've been Unwitting Pawns in the Storm King's plan all along makes its way through their ranks.
 * At the end of Michael Crichton's Timeline,
 * While we don't get to see his reaction in the films, in Death Star Tarkin has enough time to shout "Unthinkable! Unthinkable!" as his precious Death Star explodes.
 * At the end of The Last Battle the Calomene Warlord Rishda gets a huge one when
 * In one of Roger Zelazny's Amber series, a traveler encounters a demon guarding a bridge. The demon draws a (literal) line in the sand, and makes a Badass Boast about the consequence of crossing it. The traveler points out that there is one specific kind of being who could easily defeat the demon. The demon admits this is true, but thinks the encounter highly unlikely. The traveler then steps across the line...
 * Second Stage Lensmen: Kim Kinnison has been playing a long game, working his undercover way right up to the top of the Thralian dictatorship. When he comes back home after a battle, with a Patrol fleet disguised as the Boskonian one he's just annihilated, his twelve Dragons are summoned to meet him. Cue the Oh Crap when not only are they disarmed, but the man they thought was the Capo di Tutti Capi among the Boskonians climbs out of his armour with a Lens on his wrist.
 * From Under the Dome: Rusty has this reaction when he realizes that
 * In The Stand Flagg and his followers all freak out when they see what Trashcan Man brought back with him from the desert:.
 * In the Dark Tower's final novel The Dark Tower, Walter (a.k.a. the man in black) has one when he realizes
 * Also in The Dark Tower, Mordred has one when he realizes
 * In Passage to November: oh so many:
 * As the Great Lakes Storm of 1913 intensifies, Captain McTavish and his wheelsman look on in horror as another lake freighter swings too close to the SS Longhope-- they avert the impending collision just in time to see the monstrous waves tear the other boat to pieces and drag it to the bottom of Lake Huron.
 * Still believing all will end well, Clara Grace follows the First Mate to the deck... only to discover  of the crew swinging out the last remaining lifeboat
 * but likely dying of exposure, Clara Grace must watch as bits of wrecked ships  are violently slammed ashore.
 * Also becomes a Break the Cutie moment when she realizes that Captain McTavish
 * There's a great one in Excession when the ship that's been following the Sleeper Service realizes that it's converted all its internal volume into engines.


 * In Bloodstone, part of the Stones of Power series by David Gemmell, the Big Bad realizes that the legendary "Sword of God"
 * This happens to Weed from The Legendary Moonlight Sculptor a lot
 * All the way back in The Bible. Specifically, the Book of Esther. More specifically, when Haman realizes he's inadvertently ordered the death of the Queen, whom her husband the King values enough to have been willing to offer up to half his own kingdom at her request.
 * In the Sword of the Stars novel The Deacon's Tale by Arinn Dembo (one of the game's writers), the protagonist Cai Rui is investigating a colony destroyed by the so-called Rippers (AKA Black 13). Then his assistant finds the last message sent from the colony, which never arrived. It was sent over a year ago. Except the distress signal arrived only last week. Cai turns on his motion detector and finds hundreds of signals rapidly closing in..
 * The Robert E. Howard short story "The Extermination of Yellow Donory" is a series of Oh Crap moments.
