Villainous Breakdown/Literature

Examples of s in include:

Discworld

 * Lord Hong in Interesting Times goes from a smooth, scheming, would-be Vetinari of near-perfection to just another raving tyrant.
 * Wyrd Sisters had Duke Felmet, who becomes more and more unhinged as the story progresses from the guilt of killing his brother for the throne of Lancre. And from the fact that everyone seems to know, but not care. The citizens of Lancre are more the sort to think that king being killed in usurpation really does count as "Natural Causes" than the sort to rise up in arms over a beloved ruler's death only to be tragically put down. They don't even seem to care that Felmet and his wife are ruling the land with an iron fist: "You couldn't oppress a people like that any more than you could oppress a mattress."
 * Reacher Gilt in Going Postal goes through a subdued form of this trope, going from the perfect con man to someone realizing he's been duped by the ultimate con.
 * And then there's Cosmo Lavish in Making Money. He finally snaps right at the end, but it has already become evident as the story progressed that he's been going odd in the head from the start, even while his plans still seemed to be working. He's been having a potential villainous breakdown the whole time, just waiting for something to trigger it. The whole thing is symbolised by the finger on which he's wearing a far too small ring, which starts to sound more and more worrying, until near the end when his glove comes off--what's happened to it is revealed much the same way as what's happened to his mind.
 * Count Magpyr in Carpe Jugulum is a polite, urbane sort who is almost able to convince you that he really is working for the common good in having people queue up to have their blood drunk. After he's been Weatherwaxed, and the villagers turn on him, his control starts slipping, until he reaches the point of threatening babies and killing dogs.

A Song of Ice and Fire

 * , after it becomes clear that he will get a rather different "crown": "You cannot touch me, I am the dragon!"
 * , as he fights Oberyn Martell, gets progressively more enraged. A combination of his exceptionally dim wits and the realization that he is being publicly accused of his crimes in front of the entire court leads to him screaming "SHUT UP!" at Oberyn again and again.
 * , after the Brave Companions and the Northmen take his castle, ends his career as a Complete Monster by revealing himself to be a Dirty Coward and weeping and crying before he is
 * has a pronounced one after she is imprisoned by the Faith Militant in A Feast For Crows.
 * remains his usual composed, snarky, debonair, and uncaring self despite being defeated in battle and imprisoned. But when, he goes completely to pieces, and loses the will to live. He gets better thankfully fast, with a little help, which leads directly to a Heel Face Turn.
 * , when she sees her childhood crush forcibly kissing Sansa Stark, goes completely insane, trying to throw poor Sansa (who did not instigate the kiss) out of the Moon Door. Her breakdown is cut short when
 * , a particularly nasty wilding who "marries" his daughters and sacrifices his sons to the resident Eldritch Abominations, takes the suggestion that he is of dubious parentage extremely poorly:  "WHO CALLS ME BASTARD?" 
 * , a Pedophile Priest and child murderer frantically pleads with the Brotherhood Without Banners for his life.
 * , a member of the universally despised House Frey, is told to deliver a bag of gold to ensure the release of one of his slimy relatives. He brings the gold, his relative is hanged anyway, and he is next. He takes it badly.

Star Wars Expanded Universe
"C'baoth: You will die for that, Mara Jade. Slowly, and in great pain."
 * Prince Xizor in Shadows of the Empire. At numerous earlier points in the novel, Xizor is shown to consider himself superior to "mere humans" because his cold-blooded nature leaves him incapable of going into an uncontrollable rage. Turns out it's not that he can't, just that it takes a lot longer. As his palace collapses underneath him and Darth Vader lets him know that he's quite aware of Xizor's attempt to kill Vader's son, he starts to get a little... antsy?
 * Tarkin has a very brief one at the end of Death Star, when he is simply refusing to accept that his prized station has a weakness even when Luke has fired the kriffing torpedoes in. Essentially, it boiled down to "Unthinkable. Unthinkable-" boom.
 * A very, very minor one in The Thrawn Trilogy. Grand Admiral Thrawn was able to anticipate and counter almost anything the Rebellion and anyone else did. Almost. His reaction when those things he hadn't anticipated all came together to thwart him was to get maybe a little flustered, a little distracted, enough so that he didn't see the Bodyguard Betrayal until it was too late. Though, to his credit, after being stabbed he smiled and said "But... it was so artistically done."
 * Thrawn's fellow Big Bad, Joruus C'baoth, has a more traditional one after Mara . Somewhat unusually, the normally unstable C'baoth actually becomes much calmer and more controlled as he's in the process of finally losing it. This just makes it creepier.


 * The Tranquil Fury only comes after he goes completely fucking berserk, in response to a much more minor inconvenience. The narration points out that the Tranquil Fury is actually scarier.

"General Melvar: Will you be wanting your office restored, or do you wish to redecorate?"
 * The real bad guys, at least for the characters in the main plotline, of the Hand of Thrawn duology are the Big Bad Triumvirate of Moff Disra, Major Grodin Tierce, and the Con Man Flim. They work to make it look as if Thrawn has come Back from the Dead. When Pellaeon exposes their whole plot at a crucial moment, Tierce has an incredibly sudden, violent breakdown/MotiveRant If you read carefully there are hints of this, like the way he very slowly changes over the course of the novel and the way he comes up with tactics becomes creepy.
 * It apparently happens to Ysanne Isard in slow motion during The Bacta War; someone has broken out of her secret prison, parts of the Empire she rules are splintering off, and she's been forced off of Imperial Center. The Dragon notices her changing, she notices it too, and soon the captain of one of her Star Destroyers is defecting to the New Republic and sending her a message where he calls her insane. Apparently she's better by Isard's Revenge, though.
 * Nope! She's composed, but still quietly obsessing over her defeat, so that the next stage in her plan is easily predicted, to her ultimate downfall.
 * Zsinj's breakdown in Solo Command, when he learns that the Wraiths have not only evaded the deathtrap he set for them, but have taken a key person alive. He goes absolutely kriffing berserk, destroying everything in his office on Iron Fist, except for the messenger who brought the bad news in the first place.

Other works
""THE LAAAAAAST! I KNEW YOU WERE THE LAAAAAAST!""
 * The climax of Piers Anthony's Blue Adept sees Stile, in order to win his Great Game match against Adept Red (A dance competition in which Red was demolishing Stile due to Stile's wrecked knees) throws himself into a self-induced trance to see Red as his true love, Lady Blue. Red, who had just confessed that she Does Not Like Men, completely loses it over his show of affection and goes into an Unstoppable Rage right on stage.
 * Having a breakdown is the last thing that the usually stoic King Haggard does in Peter S. Beagle's The Last Unicorn.

"Gonko: If I find the motherfucker who took my pants-- I DON'T CARE WHO YOU ARE: CLOWN, ACROBAT, BELOVED FRIEND OR RELATIVE, AN INANIMATE OBJECT... AN ASTRAL BODY... ME MYSELF... A ROCK OR A BOWL OF PICKLES... SOMETHING UTTERLY IMPOSSIBLE TO KILL, LISTEN UP: I'LL FUCKING KILL YOU! I'LL FIND A WAY, IF IT TAKES ME A HUNDRED YEARS... I'LL FIND... A... WAAAAAYY!"
 * Although he hasn't been the most composed guy over the course of the book, Grevane in seventh book in The Dresden Files Dead Beat by Jim Butcher has a Villainous Breakdown that saves Harry's (or maybe Ramirez') life-right at the instant of his death. Through the entire time he's been trying to fight Harry he's been continuing a major necromantic working, and when Ramirez strikes the killing blow, his mind snaps and refuses to accept that he's dead. As a result, he keeps trying to finish the spell, instead of casting a Death Curse that would take Harry with him.
 * According to Word of God, the Denarian leader Nicodemus hasn't been the same since Harry nearly killed him by strangling him with the Iscariot's Noose. The Smug Snake Big Bad Wannabe is now utterly terrified of Harry Dresden.
 * Arianna Ortega experiences this in book 12. Throughout the book she's been a Smug Snake, and the fact that she plans to murder a little girl purely for selfish reasons only adds to this. Eventually she faces the father of her would be victim in single combat and ultimately looses badly, getting impaled by numerous ice spears (including one as thick as a man's fist.) As Harry stands over her she simply looses her cool and first says "no no no" over and over again before telling Dresden that he is cattle. Harry responds by mocking her before blowing her head off.
 * Her dad the Red King also suffers an implosive one. After getting heavily injured and overpowered by Harry, he first summons all his soldiers despite earlier showing fear at the prospect and he is reduced from a Smug Snake Chessmaster into a screaming lunatic who inadvertently cuts one of his deputies in half.
 * Artemis Fowl's "lollipops" moment in the first book.
 * Briar Cudgeon in The Arctic Incident, Spiro's when Artemis apparently disappears in The Eternity Code, Abbot's in The Lost Colony and Opal Koboi's in The Opal Deception and The Time Paradox.
 * Billy Kong's protracted loss of composure, which eventually ends with him
 * The Extinctionists suffer a collective one
 * In Will Elliott's The Pilo Family Circus, Kurt Pilo has a particularly spectacular breakdown; convinced that his underlings are turning traitor on him and overcome by rage, he begins mutating into a monstrous demonic reptile with a habit for giggling insanely under his breath. Then, he kills every single carny in his path to killing off the suspected traitors, before being fooled into descending into the depths of the funhouse- and
 * Gonko, the normally cool-headed leader of the Clown Division has one halfway through the book, when he discovers that someone has stolen his trousers -- which are, in fact, enchanted to produce any number of useful items via the pockets. However, since most of the clowns seem to be insane to a certain degree, this is less of a mental breakdown and more of an explosive temper-tantrum. Nonetheless, whilst obliterating all furniture within reach, he screams this:

"0: Q WILL PAY. ALL THE Q WILL PAY. Q AND Q AND Q AND Q AND Q AND QQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQ..."
 * Mugabo, the Circus Magician, apparently has one every once in a while: being a gifted sorcerer and pyromancer he feels degraded at having to perform the "bunny trick," and breaks into fiery temper-tantrums when pushed into it. However, when  sabotages his tent and scrawls graffiti all over his equipment near the end of the book, he enters a fully-fledged pyrokinetic psychotic episode, resulting in the death of several carnies and the utter astonishment of the visiting tricks.
 * One of the creepier moments in Neil Gaiman's Neverwhere comes when, who has been nothing but calm, . The book compares it to lifting the lid on a container and seeing something writhing underneath. Richard notes that "in a time of scary things, it was the scariest thing [he] had ever seen."
 * In Coraline the normally sickeningly sweet Stepford Smiler Other Mother loses her cool when Coraline refuses to accept gifts and love, and she imprisons Coraline behind a mirror as punishment. This is taken to further extremes in the movie when Coraline manages to blind the Other Mother and escapes back to her world. The Other Mother responds by trying to reconnect the real world and the Other World all while screaming madly at Coraline "NOOOOOOOOOOOO! DON'T LEAVE ME! DON'T LEAVE ME! I'LL DIE, I'LL DIE WITHOUT YOU!!!!!!"
 * Emperor Jigang goes through one in Pillars of Creation when, upon arriving at the Confessor's Palace in the Midlands capital, he finds
 * Kerry Greenwood's Phryne Fisher sometimes has to cope with these.
 * In Murder in the Dark, the Man Behind the Man foamed at the mouth after The Reveal and was well on the way to being committed to an asylum.
 * In Murder on the Ballarat Train, the killer finally let go with one of these complete with a Nietzsche Wannabe speech.
 * In Queen of the Flowers, the two thugs whom Phryne's friends had been tracking down for information were soon being hunted by a ruthless mob boss, thanks to some remarks she'd made about them. When they later turned up, one got peacefully drunk, but the other went into a screaming tantrum while waving a loaded shotgun.
 * Most of the villains in Redwall books.
 * Gabool the Wild in Mariel of Redwall does it most obviously and impressively. He goes from being evil but reasonably lucid to a gibbering insomniac who can't tell his followers from his sworn enemies and starts to believe that a plundered church bell understands what he's saying and rings itself to mock him.
 * Slagar the Cruel in Mattimeo is already crazy at the start, blaming Matthias and the Redwallers for the horrible scarring on his face. By the end, he's raving, frantically reassuring himself that however events turn out, he will "win" somehow. He even plans to steal Matthias' sword, now convinced that it is magic and grants victory to whoever wields it.
 * Tsarmina in Mossflower also does this. Granted she's being driven insane by a constant dripping noise and the fact that everything she tries to destroy the resistance fails.
 * Randall Flagg from Stephen King's The Stand goes through a slow but steady Villainous Breakdown about midway through the book. A series of mishaps, such as all take their toll on his Dark Messiah persona. Near the end, when, he's so unhinged that he's reduced to pathetically whining to his right hand man to get rid of the warhead.
 * Happened to the villain of Illusion by Paula Volsky. The book is a fantasy loose retelling of the French Revolution and the Terror. As the Robespierre Expy loses his absolute control, he loses his sanity.
 * Karos Invictad in Reaper's Gale, 7th installation of the Malazan Book of the Fallen as Tehol Beddict continually outwits him, really losing it when Tehol demonstrates his superior intellect by solving a puzzle he deemed impossible (and that Tehol created, incidentally).
 * In The Saga of Seven Suns, is a classic of this trope. When things stop going according to plan, they Ski Down The Slippery Slope. I call it thus because they stop just short of jumping off entirely, but still make an impressively rapid descent.
 * In The Riddles of Epsilon, goes through one of these, betraying the proper choice as it screams at the protagonist to quit hesitating and choose one faction or the other, and
 * Harry Potter always has Voldemort close to the edge but somehow maintaining his cool... until Deathly Hallows at least, where Voldemort has so completely ripped his soul apart from his repeated killing and use of Horcruxes that he completely loses it on several occasions, at one point killing everyone in the room because a helpless goblin delivered some bad news. Even when he BSOD's during the final fight against Harry he transfers the shock of that into rage and denial.
 * Also, Bellatrix, too. Though she was insane to begin with, throughout the series, she just loses it, especially in the final battle.
 * In Romance of the Three Kingdoms, Zhou Yu is completely unhinged by the failure of his last plan against Zhuge Liang. This was probably part of Zhuge's plan: Zhou Yu's rage causes a wound to reopen and he sickens and dies shortly thereafter.
 * The Big Bad of one series of Star Trek tie-in novels starring Q, the Q-level being known only as 0, goes through a few of these. In the series of flashbacks that Q shows Picard, 0 spends decades "testing" the mettle of a powerful civilization known as the T'kon empire. As the T'kon continue to overcome everything 0 throws at them, he gets more and more pissed off, and in a childish fit of pique, triggers a supernova in the middle of their empire, completely wiping them out. In a flashback set not long after that, 0's defeat at the hands of drives him completely insane; he goes from a "charming" rogue to a deranged madman obsessed with revenge and crooning little ditties to himself. His state of mind can best be seen in the following:


 * Must be endemic to villains in Q-related novels. Q-Squared, by Peter David features the return of General Trelane, an antagonist from Star Trek: The Original Series. Trelane manages to set himself up as quite the Magnificent Bastard... until Picard faces him in a duel, and, upon figuring-out that the Captain is only playing with him, he throws a temper tantrum and reveals himself to be the Psychopathic Manchild he really is.
 * Ahab's final scene, locked in combat with the white whale in Moby Dick, produces the famous quote: "Towards thee I roll, thou all-destroying but unconquering whale; to the last I grapple with thee; from hell's heart I stab at thee; for hate's sake I spit my last breath at thee!"
 * Warrior Cats: Sol, aka the king of Dissonant Serenity, loses his temper exactly once for less than half a second. It's not pretty.
 * In The Forgotten Warrior,
 * From The Tell-Tale Heart by Edgar Allan Poe. After murdering someone and hiding their body in pieces under the floorboards, he begins hearing the sound of his victim's heartbeat. Finally, he just confesses to the murder and tells the police where the body is.
 * In The Color Purple, Albert experiences this after Celie calls him out. He just loses his cool, stammers incoherently, and suffers a mental collapse. Ultimately, this forces him to change, turning him from a Complete Monster to a legitimately nice individual
 * In the Outlander series, Captain John Randall normally, in all his villainy, has two main expressions: arrogant calmness, and being annoyed. The first time he's shown to completely break down sobbing is when he confesses to Jamie that he loves him, and goes completely psycho when Jamie refuses to respond in the affirmative when he orders Jamie to tell him that he loves him too.
 * In John C. Wright's War of the Dreaming, Azrael de Gray has a comb*
 * Hatsumoto from Memoirs of a Geisha already started losing it when she found out Mameha had taken Sayuri as her little sister and training her to become a geisha, trying several tactics to beat Sayuri, showing just how desperate she was, but Mameha would find ways to best her instead. Once Sayuri became a much more successful geisha than her at such a young age, Hatsumoto really does lose it. And Mameha had no trouble deliberately driving her further off the edge. Which she would eventually succeed.
 * Animorphs largely averts this by having most of the villains start off Pre-broken-down. However, when David finds out he has been deceived and trapped, he begins sliding into this, and when he finds out that his fate is to be trapped in the body of a rat for the rest of his life, he slides over the scale. All through the two hour morph limit, and up until they transport him out to a small island and leave him, he never stops screaming the word "No", even after they leave. Understandable, considering the circumstances. Even Rachel is haunted by that experience throughout the series.
 * Big Bad Visser Three (who becomes Visser One near the end) being one of the already broken down villains, has a reverse breakdown when he is finally defeated. For the first time in the series he is calm and soft spoken. He simply slumps down and quietly accepts that the Animorphs won.
 * Peter Teleborian, a Smug Snake and Complete Monster who physically and emotionally abuses the children placed under his care suffers this big time in the climax of The Girl Who Kicked the Hornet's Nest. As his testimony is ripped to shreds by the lawyer of of one of his former victims he looses his cool and can only stammer; when the cops come to take him away for possessing child porn, he can't even bring himself to speak he's so shocked.
 * Critical Research Failure and Dan Browned aside, the 'Dan Brown' novel Angels & Demons has a particularly spectacular example of this with the popes aide Carlo Ventresca, who poisons the now-late pope and manipulates a series of events, involving the assassination of the preferiti and the holding of the Vatican hostage, just to turn the world against science only for the penultimate scene of the book to reveal that A)the pope committed no lie or falsehood in his service as a priest and B) Carlo Ventresca had killed his own father who'd sired him completely through scientific means just to add insult to the injury of his hatred of science. What followed after this arguably combines Villainous BSOD and Redemption Equals Death.
 * In John Gardner's Grendel, the eponymous monster who has been philosophical and introspective while he terrorizes the Danes throughout the book has a breakdown when he finally meets someone stronger in Beowulf. Grendel is reduced to blindly running away while crying for his mother after Beowulf tears off his arm.
 * Sisterhood series by Fern Michaels: In books like Sweet Revenge, Lethal Justice, Free Fall, and Hide And Seek, the Vigilantes will drive the Big Bad into this, and then go directly to them to administer justice face-to-face. Sweet Revenge has Rosemary Hershey suffer one spanning almost the entire book. First she finds out that Isabelle Flanders, the woman she framed and ruined, is back in action and is preparing to sue Rosemary. Then Rosemary gets more than one envelope containing pictures of the three people she killed, and images of her at the trial, with words like "thief" and "liar" scrawled on them. She is told by her husband Bobby Harcourt that he wants a divorce. She finds out from her horoscopes (she puts a lot of stock in it, apparently) that bad things are going to happen to her in the near future. She gets an original set of blueprints made by Isabelle, which Rosemary thought she destroyed, and she wrecks her bathroom in a frantic attempt to destroy it. She gets questioned by reporters about the trial. The big important men she slept with are questioned by said reporters, and these men bombard her with phone calls. She ends up firing all her employees when they can't come up with a good set of blueprints. She seems to regain her composure when she gets a good set of blueprints delivered to her. However, when she and Isabelle Flanders go to an event in which their architectural blueprints will be judged, Myra comes up and reveals to the entire architectural board that Rosemary and Isabelle's blueprints are exactly the same, with their signatures being the only difference, and that as far as it can be determined, Rosemary plagiarized Isabelle's work! By the time the Vigilantes go to Rosemary and threaten to bury her alive if she does not confess to her misdeeds, Rosemary has lost it. Oh, and it doesn't need to be said that Rosemary went to an institution and may never become lucid again by the end of the book.
 * James Taggart suffers a truly devastating Villainous Breakdown at the conclusion of Atlas Shrugged; when he realizes that he would rather kill John Galt than survive himself, he suffers Mind Existence Failure and enters what is implied to be irreversible catatonia. He exits from the plot forthwith.
 * Septimus Heap: DomDaniel suffers a Villainous Breakdown including begging for mercy when he's spotted by Marcia Overstrand as having tries to use his Apprentice's body as his own to fool them.
 * The Book of Lost Things: Once the Crooked Man's plans are finally thwarted,
 * Rumpelstiltskin: When the queen reveals that she knows Rumpelstiltskin's name, foiling his plot to steal her child, his reactions vary depending on the edition. The early editions simply have him leaving in a huff. The later ones have him going so insane with rage
