* In ''[[Literature/AliceInWonderland Through the Looking Glass]]'', Alice meets the White Knight, who is crazy prepared (emphasis on crazy!). He has a mouse-trap on his horse's saddle and his horse wears anklets to prevent shark attacks. He keeps the empty plum-cake plate Alice is holding, just in case they find any plum-cake.
* In ''Literature/AndIDarken'' Lada relentlessly drills her regiment of Janissaries with a game called Kill The Sultan, where they imagine (and act out) all the different ways someone could assassinate Mehmed and therefore protect him from these, as well as assessing what holes in his security need patching. If someone gets Mehmed's sash, he is felt effectively dead. Methods include Lada dressing up like a harem girl and infiltrating the harem (though she may have interior motives). Even Mehmed lightheartedly tells her that no one puts as much effort into trying to kill him as Lada does.
** Lada out to be ProperlyParanoid...and she already was justified before [[spoiler:Mehmed's third assassination attempt]] because by that point he had already [[spoiler:been through ''two'', at least one committed internally.]]
* In his book ''The Bad Book Club'', Robin Ince talks about ''The Correct Guide to Letter Writing'', which contains over 500 different letter templates. They start off sane enough with 'From a commercial traveler, suggesting special terms' but gradually get more crazily specific ('Accepting an invitation from a Gentlemen to Lunch at a Restaurant' is different from 'Accepting an invitation from a Gentleman to a Dinner and Theatre Party' apparently).
* Taken to a serious level in David Eddings's ''[[Literature/TheBelgariad Malloreon]]'' series. Although not properly revealed until the final book, The Dark (and its agents) showed an unreal amount of advance planning for its conflict with the series' protagonists: ''always'' possessing a fallback plan whenever something didn't work. It is eventually revealed to be part of its fundamental mentality: the idea of a predetermined perfection. The Light is no slouch either...it has a tendency to place knowledge in people's minds or has them do something so that they'll remember about it ''hundreds'' of years later when they need it. Also, twice in ''Belgarath the Sorcerer'', it altered weather patterns in order to give favorable odds to the Child of Light, the more extreme example being making it rain near-continually for ''twenty-five years''...all to create a storm in a specific place that buried an unfriendly army under several feet of snow.
** The Eternal Man himself once does this in ''Literature/TheBelgariad''. After repeatedly explaining how much magical power it takes to change the weather and how "noisy" magic is to someone with the right senses, the weather changes to just what Belgarath needs just when he needs it to do so. He explains that he set up the weather patterns required by making small changes thousands of miles away ... several months back, when he figured it would be safe because no one would be "listening."
* In the ''Literature/BelisariusSeries'', Valentinian knows everything about every possible situation in combat that might come up. He even trains a prince to be able to fight with a shovel in case he finds himself without a sword.
* In ''Literature/{{Below}}'', this is a vital skill for anyone who dares to enter the [[DungeonCrawling underground ruins]] of the Elder Kingdom. It's critical to take the right supplies, learn as much lore as possible, and make the most of any opportunities along the way. Brenish and Gareth have studied the survivors' stories so obsessively that they're both experts. Gareth is kitted out with nearly anything the party needs, plus he's practiced with just about every weapon known to man. One of Gareth's henchmen also qualifies, bringing along extra items and a skill set no one else knew about so he could save the day at a critical moment. Brenish is forced to get by on only wits and knowledge, but as he accumulates a secret stash of found items he becomes pretty crazy-prepared himself.
* The main protagonist from ''Literature/BlackTideRising'' is a former special forces soldier with some family and friends in high places to watch out for potential problems. To discuss them (a ''wide'' range of possible disasters), he and his friends/family have enough plans for different apocalyptic scenarios that they [[CodeEmergency have a code]] [[PoliceCodeForEverything for every single one of them]].
* Jerin Whistler of ''Literature/ABrothersPrice'' goes nowhere without his lockpicks. He usually has two weapons on his person, too, but he does give those away when asked to disarm. It is family tradition - his grandmothers were spies, and they apparently saw no reason to stop doing something that worked ... as, teaching their kids thieves' cant and lockpicking, and probably lots of other things, too.
** Cira seems to have lots of interesting items in her saddlebags, too.
* In Creator/DaleBrown novels, Sky Masters aircraft come with the equipment and code necessary to mount Russian weapons just in case their crews ever need to use them, as noted in ''Wings of Fire''.
* ''Literature/ButlerParker'': Parker has numerous ball-point pens that he has retooled to work as a blowtorch, blowgun, flashbang etc., has a 'universal umbrella' with leaded handle that can shoot blowgun darts, has a completely reworked taxi with lots of tricks...
* Aladavan, a [[TheFairfolk sidhe]] wizard in ''Literature/{{Cerberon}}'', always has something up his sleeve to get himself out of just about any situation, and he can quickly improvise a solution with whatever he happens to have on hand. Aladavan's wagon is packed full of useful things, including a folding table, a collection of magic wands, treasure chests, a library, and a spare wagon with a trunk full of emergency supplies. He stocks his [[BagOfHolding satchel]] with any number of items that he anticipates might be handy at a moment's notice, including an enchanted sword, a bottle of wine, and a flaming timber.
* ''Literature/CradleSeries'': Lindon comes from a clan of tricksters, was born exceptionally weak, and has the terrible luck to repeatedly have to fight people far stronger than him. His guiding philosophy is essentially "if I stuff enough into my pack, I'll always be ready for anything." That hasn't always been true, but he is known for carrying around a massive pack stuffed with all sorts of odds and ends.
* In ''Literature/ADeepnessInTheSky'' by Creator/VernorVinge, Pham Nuwen is crazy prepared. He's been preparing for hundreds if not thousands of years, collecting the most advanced technology from all over the galaxy and disguising it as innocuous materiel. He's learned and created countless secret programs and backdoors on the computers. All of Pham Nuwen's toys are standard equipment on Queng Ho ships, yet nobody else knows about them. Everybody is, although not to the same extent. In ''Literature/AFireUponTheDeep'', a children's toy computer, explained as being outdated but hung onto for sentimental purposes (it was shaped like a stuffed rabbit) includes as a standard feature 'uplift protocols' to allow any tech level short of flint and bone knapping stone age to raise the technology to build a subspace radio capable of reaching civilization to call for rescue.
* ''Literature/{{Discworld}}'':
** ''Literature/TheAmazingMauriceAndHisEducatedRodents''. Due to Malicia's [[GenreSavvy awareness]] of the TheoryOfNarrativeCausality, she carries an adventuring bag with such items as a grapnel, a rope ladder, laxative for surviving on a coconut diet on a deserted island, and cotton-wool for blocking the vents of a giant underwater mechanical squid. She lives several hundred miles inland. These come in handy repeatedly, though not for their intended purpose because Malicia is WrongGenreSavvy.
--->'''Keith''': If you think like that, you end up taking ''everything'' in case of ''anything''!
--->'''Malicia''': That's why it's such a big bag.
** Vorbis, antagonist of ''Literature/SmallGods'', had a very weird form of planning which was described as such: "You had to have a mind like Vorbis's to plan your retaliation ''before your attack.''" In other words, he planned an assault on Ephebe (with resultant tragic losses) only after starting an even more elaborate means to get back at them ''first''.
** Mr Teatime, an assassin in ''Literature/{{Hogfather}}'', made a hobby of working out ways to kill anthropomorphic personifications, such as the Hogfather, the Tooth Fairy or even Death. This came in very handy in his next contract.
** Vetinari, the scheming Patrician of Ankh-Morpork, knows that when a ruler is overthrown the overthrowers tend to lock the ruler away in the deepest, dankest cell of his palace's dungeons. Hence, Vetinari ensured that while the deepest, dankest cell's door has a heavy-duty lock on the outside, all of the deadbolts and bars are on the ''inside''. He also has the key hidden behind a brick in the cell wall so escape can be performed at leisure. Training the local sentient rats to run errands didn't hurt either. Yes, the Patrician arranged for his jail cell to have ''room service''.
** The Lancrastian Army Knife contains ''everything'' a soldier in the field could need. The trope is played with, as it's explained that if it had contained ''absolutely'' everything a soldier might need, it would have been too big and heavy to carry around, so most of the suggested items (such as a "small tool for winning ontological arguments") had to be left out.
** Commander Vimes has liberally booby-trapped his home and all non-direct entrances to his office, knowing that various individuals would be contacting the Assassin's Guild about removing him from office. The effectiveness of these precautions (and his increasing importance in Ankh-Morpork's political landscape) has resulted in the Guild refusing to take any more contracts out on him. These days, the Guild uses him as a training objective for know-it-all students: all the trainee needs to do is get a glimpse of him without getting caught by a trap. So far, nobody has succeeded.
** In ''Literature/{{Pyramids}}'', Pteppic gears up for his final exam at the Assassins' Guild with so many weapons, housebreaking tools, and protective items that he falls over when he tries to move.
** Witches can create a tool known as a Shambles in order to discover impending danger and other information. There are three basic rules for creating one: it must be made on the spot, it must contain something alive, and it must be solely made out of what the witch happens to have in her pockets at the time. In a combination of this trope and ExactWords, most savvy witches are careful to carry around an interesting assortment of random objects in their pockets just for making shambles, generally including a living insect in a small box or a fresh egg.
* Literature/DocSavage has a spyhole and control panel within his private elevator that can start a film projection of him getting killed in a selected way ([[{{Squick}} machine gun, acid, explosion etc.]]) onto the lobby door of the elevator before it opens to fool anyone who would ever try to personally attack him in the lobby of the Empire State Building. It is only used once in 16 years.
** In fact, many, if not most, books in the series contain examples of this trope.
* ''Literature/TheDresdenFiles:'' Harry Dresden's continued existence is down to being the luckiest man alive (except when it comes to [[PerpetualPoverty money]], women, or [[DestructiveSaviour buildings]]) and being CrazyPrepared or capable of being CrazyPrepared with two hours notice and access to a UsefulNotes/{{Walmart}}.
** He has quoted Foghorn Leghorn on one occasion when he pulled something similar out of thin air, as he's wont to do.
** CrazyPrepared, and also ProperlyParanoid. He really does have a whole lot of powerful, ruthless enemies. He almost never leaves home without a bulletproof leather jacket and magic rings that can release enough force to flip a car.
--->'''Harry:''' Paranoid? Maybe. But just because you're paranoid doesn't mean there isn't an invisible demon out there waiting to eat your face.
** He carries water balloons filled with holy water in a box under the driver's seat of his car ''just in case'' he gets jumped by vampires while parked. He also carries an enchanted chain with an electrical plug designed to be flung at an enemy and then connected to an outlet as a magical taser in case he gets attacked indoors, which he can smoothly and effortlessly draw thanks to practicing the draw thousands of times. He even built what amounts to a voodoo doll of the city of Chicago to use as a focus to track down bad guys running around in his town.
** After a nasty incident involving a cunning villain who figured out that since his shield spell only blocked kinetic force, [[spoiler:throwing enough fire at him would still cook him, shield or no]], he made a new one that would block everything he could think of that it would be even remotely possible for someone to throw at him.
** The series also shows how Harry becomes more ProperlyParanoid as he goes along-in the first few books, he mostly relies on the IndyPloy, but as more and more weird stuff keeps happening to him- like being chased by an invisible demon which he has to use air freshener to detect- he becomes this trope.
** In ''Literature/ColdDays,'' we find that Molly, his apprentice, is also this. [[spoiler:Not only does she anticipate that Harry will come back to life, but she's actually set aside a room in her apartment for him to crash in when he does, his house and legal identity being more or less gone.]] Also crosses over with GenreSavvy; their world is an UrbanFantasy stuffed to the gills with tropes, and what trope is older than [[spoiler:the protagonist coming BackFromTheDead?]]
*** Although the short story ''Bombshells'' actually gives her a reason for knowing that; [[spoiler:Lea told her]].
** Donar Vadderung, [=CEO=] of Monoc Security, keeps his base stocked weaponry to fight any war. The selection goes from sharp sticks to top-of-the-line modern small arms, and there's enough ''of each'' to outfit an army. He also recruits only the most competent staff, and maintains an excellent spy network. His secretary explains that "one can only have as much preparation as one has foresight". Of course, the fact that Vadderung is in fact [[spoiler:Odin, and by a strange turn of events, Santa Claus,]] explains a lot of things.
** The White Council has standard paperwork for if a Warden comes back from the dead. It doesn't get used often (it's beyond the abilities of any human wizard), but Rashid thinks he "remembers all the necessary forms.”
** It's stated that wizards in general try to be this trope -- while they're only slightly more durable than your average Muggle in a world full of all kinds of supernatural nasties, give them time to prepare and enough materials, and they can take on beings far more powerful than them.
* The ''Franchise/{{Dune}}'' series has quite a few of these, including [[Literature/GodEmperorOfDune Leto II]] and [[Literature/ChapterhouseDune Darwi Odrade]].
* A character in one of Lawrence Block's "Ehrengraf" short stories places title character Martin Ehrengraf on retainer to defend him on the charge of murder. For a murder he ''intends'' to commit. Ehrengraf quips, "I wish all of my clients had as much foresight as you."
* Mouse, the central character of ''The Eighteenth Emergency'' by Betsy Byars, spends his spare time working out plans for dealing with various emergencies, such as being bitten by a tarantula or attacked by a tiger. He is a 12 year old who lives in suburbia. The premise of the book is that there's an 18th emergency he hasn't prepared for; being beat up by a bully. If you must know, [[spoiler:he gets his head handed to him.]]
* ''Literature/ElephantAndPiggie'':
** Invoked in "I Am Invited to a Party!" when Piggie receives a party invitation and asks Gerald to accompany her. Worried that it might be a fancy pool costume party, Gerald convinces Piggie to attend in fancy evening wear, snorkling gear, and a costume. [[spoiler:He's right.]]
--->'''Gerald:''' What if it's a costume party?
--->''[{{Beat}}; Piggie [[AsideGlance gives the reader a skeptical look]]]''
--->'''Piggie:''' A fancy pool costume party?
--->'''Gerald:''' WE MUST BE READY!
** In "Let's Go for a Drive!", after hitting on the idea of going for a drive, Gerald decides that they need 1) a map to find out the way, 2) sunglasses if it's too sunny, 3) umbrellas if it rains, 4) bags for their stuff, and finally 5) a car. Their preparations come to naught when they realize they don't have a car, so they play pirate instead.
* This is the whole basis of Creator/NeilStrauss's new book ''Emergency'' in which he details how he learned to start worrying and become crazy prepared.
* ''Toys/EverAfterHigh'''s Little Red Riding Hood keeps a smoke bomb in her basket in case she needs to beat a hasty retreat with her basket of treats still intact. She actually uses it to [[spoiler:save her friend, now husband, the Big Bad Wolf.]]
* Raoul Duke and Dr. Gonzo, with an emphasis on "Crazy", in ''Literature/FearAndLoathingInLasVegas''. "We had two bags of grass, seventy-five pellets of mescaline, five sheets of high-powered blotter acid, a salt shaker half-full of cocaine and a whole galaxy of multicolored uppers, downers, screamers, laughers... Also a quart of tequila, a quart of rum, a case of Budweiser, a pint of raw ether, and two dozen amyls..."
** Terrifyingly, that passage comes from an actual segment of Hunter S. Thompson's journal, where he notes what he bought with the $300 in petty cash his editors gave him.
* Rufo, from Robert Heinlein's ''Literature/GloryRoad'', carries a [[Series/DoctorWho TARDIS-like]] backpack that, once removed from Rufo's back and unfolded (a process requiring several minutes of time and square meters of space) contains anything and everything that the protagonists might need on their mission. However, as his boss, Star, explains to Oscar (the first-person-narrator and protagonist), while the backpack damps out apparent weight enough to allow the wearer to lift it, its still got enormous ''mass'' and is thus very expensive to maintain and transport. Further, it has to be ''completely'' unfolded before they can get at anything they might need, making the thing less useful in the heat of battle or the cramped confines of a cave than Oscar might have liked.
* In ''Literature/GoodOmens'' by Messrs. [[Creator/NeilGaiman Gaiman]] and [[Creator/TerryPratchett Pratchett]], the ''International Maritime Codes'' include an eight-letter code (XXXV QVVX, if you're really curious) for "Have found Lost Continent of {{Atlantis}}. High Priest has just won quoits contest."
** Crowley, a demon, keeps a flask of Holy Water on hand, just in case.
** TruthInTelevision (or literature in this case): an essay in the 28 July 1934 issue of ''Magazine/TheNewYorker'' was entitled "Melancholy Notes on a Cablegram Code Book" and it mentions a bunch of these sorts of code groups in a commercial (non-secret) code. Such as LYADI, meaning "Arrived here with decks swept, boats and funnels carried away, cargo shifted, having encountered a hurricane." Or EWIXI, "Very few cases of cholera are now reported". As the essay's author mentions, some of them are just a little too disturbingly detailed.
* The ''Literature/GrailQuest'' series of gamebooks would give players the option to acquire seemingly ridiculous items, such as mechanical aardvarks and devices for communicating with crickets (not insects in general, you understand, but ''solely'' crickets). In any given book, most of these items would be useless but one or two would increase your chances of success significantly. The trick was figuring out ''which.''
* ''Literature/HarryPotter''
** Hermione, although she's only CrazyPrepared in comparison to Ron and Harry, who barely pay attention even in self-defense classes (imagine how they would be if math were actually required of them) and the pureblood wizarding world in general, which she says doesn't have "an ounce of logic".
*** In the seventh book she's playing the trope pretty straight, doing the majority of the planning and packing for the Trio's quest to locate the Horcruxes, bringing along every potentially useful item and book she can think of in her [[BagOfHolding Undetectable Extension Charmed handbag]] and the Weasleys' similarly much-larger-on-the-inside pup tent, and modifying her parents' memories to give them new identities, a strong desire to emigrate to Australia, and no recollection that they ever had a daughter, in order to protect them from the Death Eaters.
** A more straight version of this is Mad Eye Moody who hauls around a trunk primarily full of highly situational gear for fighting Dark Wizards, all this from a man who can see through walls (and the back of his own head). The fact that [[spoiler: he ''still'' got jumped by a Death Eater in the fourth novel]] shows that in the wizarding world, being over-prepared is a necessity.
** The Ministry of Magic seems to have taken this route with its visitor's entrance, which produces a badge that identifies the visitor's purpose... up to and including ''Rescue Mission''. You know, [[SincerityMode because so many people need rescuing from the government of the British wizarding world]].
* The Zhangs of ''Literature/TheHeroesOfOlympus'' have an armory in their attic that's almost as well stocked as the one at Camp Jupiter. They have everything from swords, bows, arrows, spears, even potato launchers for taking out earthborn. It comes in handy. (Don't forget the water-hose on the roof!) And yes, [[ItMakesSenseInContext It does make sense in context.]]
* This is parodied in ''Literature/TheHitchhikersGuideToTheGalaxy'', with the towel. If you have your towel with you, everyone automatically assumes you are prepared for anything and will thus be happy to lend you anything you may have misplaced (food, money, [[RefugeInAudacity spacesuits]], etc).
* ''Literature/HiveMind2016'':
** Adika has multiple defensive plans set up for Amber's unit, some of which are only known to his trusted deputies, and he checks his security measures daily. He gets annoyed at Elliott's bodyguards for not noticing that somebody had cut into his apartment's ventilation system within the past month, as he would never allow such laxity to put Amber at risk.
** The Sea Farms are this for the entire Hive system. Every Hive is required to support a Sea Farm that can be completely self-sustaining and absorb survivors from the Hive if something goes horribly wrong.
* ''Literature/TheHost2008'' gives us Melanie's relatives, but especially Jeb -- he completely overhauls a cave system to make it inhabitable, solely because he thought he'd need an ElaborateUndergroundBase someday.
* ''Literature/IDidNotGiveThatSpiderSuperhumanIntelligence'': Bismuth often outthinks Palooka Joe throughout their EscalatingWar, such as by having an escape route ready after one fight and bringing a StealthExpert villain to another to hover in the shadows and strike when necessary.
* Creator/TomClancy's ''[[Literature/JackRyan Executive Orders]]'': After the U.S. is attacked by a Japanese terrorist, President Ryan happens upon the contingency plan to attack Japan. He orders it destroyed. The narration notes they're just going to file it away.
* ''Literature/JeevesAndWooster'': Few people are better prepared than Jeeves, who in addition to knowing the exact social standing of every relationship in the British aristocracy, has a working knowledge of foreign language, psychology, fashion, economic theory (he can completely explain communist theory, despite being completely opposed to it), taxonomy (he refers to animals by their scientific names), and so on, and does it all with such cool implacability he qualifies more as a DoAnythingRobot.
* ''Literature/JohannesCabalTheNecromancer'':
** Cabal is a highly practical man whose work is very dangerous, so as such he is usually armed with at least three weapons- a switchblade, a sword-cane, and an enormous revolver. He goes past this in another book when he brings along an elephant gun as well-its usually justified in his case.
** Arthur Trubshaw, the clerk of Hell-he has thousands and thousands of forms for souls sent to hell to complete, in order for them to gain (and explain) their entry to Hell. When Cabal arrives the first time, he says he doesn't have to fill out the forms, since he's not dead. Exactly one year later Cabal returns and this time Trubshaw has a form specifically for living people entering Hell.
* Etjole Ehomba, central character of ''Literature/JourneysOfTheCatechist'' by Creator/AlanDeanFoster, carries any number of magical and alchemical gifts in his backpack. Most of these are intended for use in other applications, but prove effective in whatever crazy-ass situation he's currently facing as well. In addition, his "sky-metal sword" usually has a hidden ability perfect for whatever foe he's fighting.
* ''Literature/JourneyToChaos''
** The BigBad of the first book, [[spoiler: Duke Selen Esrah]] made sure that nothing went wrong with his EvilPlan [[spoiler: He hired an enforcer to possess the king years before hand to make sure that the king would properly abidicate after the plan was launched, instead of escaping or comitting suicide. He was also prepared for his son to betray him, despite his son being the greatest benefactor of ThePlan]].
** Sathel hides her intelligent field medic spiders on Nolien, without telling him, because a situation where Tiza is injuried and needs their help is likely to be an occasion that incapicates the spiders she hid on her as well. She also makes sure that Tiza has everything she could possibly need when going on a mission to Ceiha and then checks to make sure she has everything four times on the way to the guild lobby.
** Fairtheora has, at least, 42 emergency procedures programed into his sentinel armor. He also carries a pink bunny ear headband in case he ever needs to diminish his TerrorHero factor and make someone comfortable in his presence.
* Jarlaxle, from R. A. Salvatore's ''Literature/TheLegendOfDrizzt'' books, has a hat containing a portable hole, a feather on the hat that summons a giant bird, an infinite supply of knives, a belt that can turn into a snake or extend into a rope, an eyepatch (that he doesn't need) that can see through walls and also protects him from mental intrusion, boots that can silence his footsteps, a ring that can hurl fireballs, a cloak that makes him immune to projectile attacks, several magic wands, a maul hidden in his hat, a ring that detects lies, and a ring that protects from fire or ice. And those are only the items we know about. Do not underestimate Jarlaxle.
* Clan Korval from the ''Literature/LiadenUniverse''. Due to a contractual oversight, they're legally still in charge of the planet of Liad should an enemy try to harm the citizens. The clan has been designed to be able to financially, mentally, and physically able to fight at any given moment. Complete with TimeForPlanB emergency planning.
* ''Literature/TheLordOfTheRings''
** Sam Gamgee; for most of the first book he moans about the lack of rope (and ends up getting a coil of it during the journey anyway).
** In fact hobbits as a whole, Bilbo outfits Frodo in case he gets stabbed (justifiable under the circumstances, but none of the other hobbits have armor) and in ''Literature/TheHobbit'' Bilbo also considers a pocket handkerchief an essential part of a dragon-hunting adventure.
* When the protagonist of ''Literature/TheMentalState'' is sent to prison with nothing except a few obscure books, some curry powder and a watch that reminds him of his former girlfriend, it is assumed that he is ill-equipped to survive. However, this cannot be farther from the truth. The books help him to devise new plans for survival and the curry powder is there in case he has to deal with drug-dealers, which he eventually does. The true purpose of the watch is hidden from the other characters and the reader until the penultimate chapter. [[spoiler:It turns out that he bought the trinket himself to make it look as though it was important and convince his enemies that it could be used as his weakness should they start looking for one to exploit. It also helps to convince his enemies that his former love is called 'Rosette' rather than 'Rosemary', thus preventing her from being targeted]].
* ''Literature/MerkabahRider'': The Rider tries to be prepared for any supernatural threat he might encounter. He carries so many protective amulets and talismans that he clinks when he walks. And, in case he should ever be stripped of all of his other protections, he has stitched the 72 names of God in threaded gold into the inner seam of his ''rekel'' coat.
* ''Literature/TheMoomins'' series, by Finnish author Tove Jansson: Moomin's mother never parts from her handbag. When another character asks her what she is carrying that is so important, she replies: "Oh, stomach medicine and clean socks and steel wire and other things that might be useful". Also, her handbag frequently contains exactly the thing the family needs.
* Master Miller was shown to be this in the Novelization for ''VideoGame/MetalGearSolid'' before he got offed. Although he had a main arsenal within the house, he also kept various weapons in each and every room in case someone managed to somehow infiltrate his house. However, it didn't save him from the gas.
* Averted in ''Morlock Nights'' by K.W Jeter. In this story, the Time Traveller from Literature/TheTimeMachine went back to the future to rescue his Eloi lover. Unfortunately, he only brought with him a lantern, a rifle and a box of cartridges so he's poorly equipped. As well, TheMorlocks he encountered were the dumbest of their kind, so on his return, the Morlock leaders and their minions overwhelmed and killed him before taking the time machine.
* ''Literature/MrTheodoreMundstock'' follows the eponymous character, a Jew living in Prague during World War II, as he prepares for deportation into the concentration camp. Going through everyting, from training how to carry his heavy luggage to preparation for his execution, we can see him turn literally crazy prepared for his stay at the concentration camp. What he didn't prepare for was [[spoiler:the car that ran him over just outside camp.]]
* Cookie from ''Literature/{{Nation}}'', with his floating coffin containing everything a sailor lost at sea might need to survive.
* Toni Ware's shoplifting techniques in ''Literature/ThePaleKing''.
* ''Literature/ThePendragonAdventure'': What some of the acolytes and Travelers are like, which certainly comes in handy down the road. It's more impressive given the rule that everyone must "use what the territories provide", i.e. you resupply at every stop.
* In ''Literature/{{Reamde}}'' by Creator/NealStephenson, the Chinese hacker group have spent some time devising a plan for escaping a zombie invasion, on the grounds that this is far more likely than a police raid. This turns out to be unexpectedly useful when the plot starts happening to them.
* ''Literature/{{Redwall}}'':
** In ''Rakkety Tam'', just before the fight with Gulo, Tam [[spoiler: sharpens the edge of his shield. During the fight, the shield is torn from his arm and embeds itself edge-on in the ground. Later on, Gulo is thrown into the air, and lands just right for the protruding shield-edge to decapitate him.]]
** Damug Warfang from ''The Long Patrol'' is a cunning leader who has plans for all sorts of situations.
*** He appoints an advisor, Lugworm, but has another, secret, advisor who he trusts more, because as Damug says, it's important to have "watchers watching watchers."
*** Damug knows about Borumm and Vendace, the {{treacherous advisor}}s who are plotting against him, well before they actually try anything. He even knows that Lugworm knows about them, so he asks Lugworm if everyone approves of Damug as a leader to see if Lugworm will mention them (as a test of Lugworm's loyalty.)
*** Damug figures out the night that Borumm and Vendace will try to kill him. On that night, he wraps a bunch of rocks in his cloak to make it look like he's sleeping, and has ten heavily armed guards hide nearby. Borumm and Vendace are fooled by Damug's trap and captured by the guards.
*** Damug is constantly sending out scouts to investigate new areas before his army reaches them.
* Jack West Jr. and his team in his series written by Creator/MatthewReilly. Their farm in Australia gets attacked by paratroopers equipped with jeeps. They escape by driving through a bridge booby trapped with wheel puncturing spikes, into a river over a concealed concrete ford, into a 747 JUMBO JET hidden in the hillside and release a giant anti-aircraft bouncing bomb to take out 2 fighter jets. Crazy Prepared just doesn't come close.
* Nakor in ''Literature/TheRiftwarCycle'' is crazy prepared, he can access a table full of useful items he has already assembled in a sealed cave through a [[CoolGate rift]] in his seemingly empty rucksack [[spoiler:including a royal Keshian falcon, long thought extinct]], and a near endless supply of oranges through a separate rift to a fruit merchant's shop! [[spoiler:Nakor is a fragment of a god, so a little foreknowledge probably helps]]
** After falling into seawater we find out that the rift goes both ways, and that the fruit merchant will probably have at least one ruined barrel of fruit, after which the rift instead starts to produce apples.
* ''Literature/RiverOfTeeth'': According to Houndstooth, Hero is not only crazy-smart but also always crazy-prepared for any eventuality. Despite there being little chance that their plan might go wrong and the bomb's Hero prepared may not go off, Hero prepares a back-up plan anyway. Don't cha know, they end up needing the back-up bombs.
* ''Literature/{{Safehold}}'':
** Madame Ahnzhelyk is remarked as planning ahead with a vengeance when it comes to her efforts to reform (and later subvert) the Church of God Awaiting. This is brought int full prominence in the fourth book ''A Mighty Fortress'' where plans she set up ''years'' ago (even before the current antagonist ever came into power) are used to evacuate as many victims of an upcoming Inquisition purge as humanly possible. Her efforts secure the escape of about a tenth of the intended victims, which include the families of prominent vicars and an archbishop.
** The Church of God Awaiting's creators could be seen as this. As noted in ''A Mighty Fortress'', because the Church was started as a PathOfInspiration to enforce MedievalStasis, but Safehold was still a terraformed planet not originally meant for humans, the "Archangels" had to come up with divine or miraculous explanations for every possible known phenomenon known to man so people wouldn't go and ask "''Why'' does X happen?" They managed it for close to a millennium before it started coming apart.
** Decades before the main plot, while he was still Crown Prince of Corisande, Hektor Daikyn did the unthinkable and planted a double-agent [[spoiler:within the ''Inquisition'']]. While not intended for it, this act ultimately secured the successful rescue and HeelFaceTurn of [[spoiler:his spymaster, his daughter and his younger son well after his own death]].
* In the ''Literature/{{Sandokan}}'' series, Sandokan and his crew tend to prepare for anything. They are imprisoned in a chamber being filled with water? Instant bomb to open the way. The Royal Navy is about to attack Mompracem? Royal Navy, meet King of the Sea, Sandokan's new ironclad warship that outguns anything in the East Indies Station. East Indies Station has surrounded Sandokan's ironclad with five warships on par with the King of the Se-HOLY CRAP, HOW DID THAT BRITISH SHIP EXPLODE WITH NO APPARENT CAUSE?!
* In Paula Harrison's book ''The Secret Promise'', Princess Jaminta attends a royal banquet, and just happens to bring a screwdriver (the tool, not the drink) along with her. Which she needs shortly.
* ''Literature/TheShelter'' starts out as the story of forty people sharing a bomb shelter as civilization collapses around them. Then it expands as the cast become the leaders of a New Confederacy fighting a second Civil War.
* The protagonist of Creator/HPLovecraft's "Literature/TheShunnedHouse" suspects that he has discovered a vampire, but knows better than to rely on a wooden stake and hammer, instead bringing a pair of flamethrowers and a ''[[EnergyWeapon Crookes tube]]'', "in case it proved intangible and opposable only by vigorously destructive ether radiations". [[WrongGenreSavvy This being a Lovecraft story]], it turns out neither of these are appropriate weapons for what's actually going on, but props for trying.
* ''Literature/StarterVillain2023'': Jake Baldwin set up a cover identity for his nephew as soon as he was born and kept it updated. He also had him under continuous surveillance and set up a backup safe house for him just in case he was targeted by Jake's enemies.
* ''The Survivalist'', hero of the 1980s action novel series by Jerry Ahern. [=Ex-CIA=] agent John Rouke has a well-stocked underground retreat enabling him to survive not only WorldWarThree, the collapse of society and Soviet occupation, but later the extinction of all life on Earth!
* ''Literature/TeenPowerInc:'' In "Beware the Gingerbread House," [[spoiler: Mrs. Crumb]], an accomplice of ruthless crimelord Sidney "The Wolf" Wolfe, has spent years keeping a bag of charred bones in her closet to fake her death in an explosion if she ever [[YouHaveFailedMe fails him.]]
* In Nick Pollotta's ''That Darn Squid God'', Prof. Felix Einstein brings up a small bag of dirt. What for? [[spoiler:It helps him to get off The Flying Dutchman. By redeeming the damned ship and its crew.]]
* ''Literature/TunnelInTheSky'' plays with this:
** Rod averts the trope on his sister's advice, taking only a knife, pack vest, and rations on his off-world survival test. Deacon Matson even asks why he didn't arrive with camping equipment and popular outdoor gadgets like the other students. His sister's advice is based on the philosophy that if someone relies too much on equipment and weapons, they will be less prepared mentally and prone to overconfidence. She uses as an example an experience she had during her own survival course. Having lost her firearm early on, she was subsequently forced to flee from a predator she would have confronted had she been armed. She only learned later that the weapon she had been carrying would have been ineffectual against that particular animal, and had she still been armed she would certainly have been killed in the encounter.
** Matson subverts the trope during the final inspection as students are expected to be prepared for any reasonable survival circumstances. Any student without cold weather gear and risking ExposedToTheElements fails automatically, despite Matson knowing they wouldn't need it for this test. Conversely, a few students prepare for vacuum or toxic environments and Matson fails them for bringing pressurized space suits: environments immediately lethal to humans aren't a reasonable test parameter, unless the students are given explicit advance warning of conditions.
** Averted also in that almost literally the first thing Rod stumbles over on his arrival into the test zone is the corpse of a student who had prepared himself with a lot of camping gear and a highly advanced ultra-expensive man-portable energy weapon. He'd been followed, ambushed, and murdered specifically so somebody else could steal his fancy gun.
* In ''Literature/{{Victoria}}'', William Kraft ''always'' has a contingency plan. When the Deep Greeners revolt, he not only knows about it before the government, he also has a non-violent (or non-lethal, at least) solution ready for the crisis.
* ''Literature/VorkosiganSaga'': Imp Sec headquarters' security is obsessively detailed and redundant including compartmentalization and internal life support that reminds Miles of a spaceship plus refusing to allow building across the street to ensure a clear field of fire.
* ''Literature/WaxAndWayne'': Steris is a meticulous planner, to the point that she insists on trying to plan a disruption for her own wedding, under the logic that her fiance, being a rough-and-tumble gunslinger cop, will attract ''some'' sort of trouble, and it's best to make her own before that can happen. In ''Literature/BandsOfMourning'', Steris had ''six'' copies of their wedding pendants made. Considering that four of them never made it to the church, this falls into ProperlyParanoid. At the end of the novel, [[spoiler:she indirectly saves hundreds of lives by hiding a warmth metalmind in her notebook. This saves Allik's life, and lets him save his people, who then fight off the Set and capture many members of the conspiracy]]. In ''Literature/TheLostMetal'', she reveals she's made multiple plans for how to evacuate Elendel City in case of varying emergencies (earthquakes, fire, tsunamis etc.). When one of her plans is put into motion the Governor is so impressed by its effectiveness that he offers her the job of Disaster Preparations Officer so she can oversee all safety arrangements in the future.
* In Creator/HarryTurtledove's ''Literature/{{Worldwar}}'' series, the [[LizardFolk Race]] arrives to Earth expecting a CurbStompBattle against a bunch of Medieval knights. While what they find definitely shocks them (they arrive in the middle of UsefulNotes/WorldWarTwo), they still give humans a hard time, as their military technology is decades (in our understanding) beyond what humans have. It could be understood that they brought tanks, jet fighters, helicopters, and machineguns to quickly subdue the local population with a display of awesome weaponry. However, there is no justification for them bringing dozens of nukes to fight a bunch of primitives, especially since they are doing everything they can to preserve the planet for colonization. Unusually for this trope, the nukes they bring don't do much to help the lizards, as humans haven't advanced yet to the point where EMP is harmful to their technology (the pulse only fries integrated circuits not vacuum tubes). Their nuking of [[spoiler:Berlin and Washington]] only serves to piss off the locals. In fact, the lizard nukes end up helping humans, as they manage to obtain some radioactive material from the lizards and interrogate several of them in order to finish their own atomic bombs ahead of schedule.
** This is eventually {{Lampshaded}} when a human asks a Race high officer ''why'' they brought far more troops and equipment than they would have possibly needed against the expected enemy and a few things they ''wouldn't'' have needed, such as nuclear weapons and anti-aircraft ordnance... And the answer is that when you go to war you prepare to go to war, and doing otherwise would be insane.
** Going by how when they first detected radio signals from Earth the Race thought someone else had invaded their target first, the implication is that they brought what was supposed to be overwhelming force precisely to deal with this situation... Something they also declared a ''very'' remote possibility, as they believed themselves far more advanced than anyone else in the universe.
* ''Literature/WorldWarZ''. White South African Paul Redeker had been hired by the government to come up with contingency plans in case of a large-scale revolt of the native African population (called Plan Orange). When the ZombieApocalypse occurred, Redeker went to his mountain retreat and, on his own initiative, adapted Plan Orange into a national zombie survival plan. Most governments in the world implemented his plan and eventually survived the war. Not forgetting the first book, ''Literature/TheZombieSurvivalGuide'', which taught the average Joe how to survive a zombie attack, with advice about forming groups of people, securing secluded land and, naturally, hoarding food, materials and weapons. It's noted in WWZ that it's useful mostly for Americans. Since the "interviewer" is Brooks himself, this is SelfDeprecation.
** Ironically, however, the US Military somehow contrived to have both covert zombie-fighting operations and to be completely stupid when the Battle of Yonkers rolled around. The people responsible for the covert ops were planning to be prepared, but ran out of time. [[note]]Specifically, they needed to build up their forces first. Critics of the book have claimed that zombies should be a cakewalk to even unprepared modern military forces, even including what basically amounted to "DM Hax".[[/note]]
* The level of CrazyPrepared going on in ''Literature/TheZombieSurvivalGuide'' is hard to imagine for anyone who hasn't read the book. He has strategies and tips for fighting zombies in almost every conceivable type of terrain (including watching out for zombies who had been frozen under snow or ice during the winter and are now starting to thaw). And, in the chapter on the pros and cons of various vehicles, he even includes tips regarding the use of Lighter-Than-Air vehicles, like ''blimps and hot air balloons''.
