->''[[NotAMorningPerson Please don't wake me]]\\
No don't shake me\\
Leave me where I am\\
I'm only sleeping''
-->-- '''Music/TheBeatles''', "I'm Only Sleeping"

The character does not so much sleep as fall into a [[ConvenientComa coma]] for eight or more hours. The alarm clock that could rouse them has yet to be built. Yelling does not wake them. Physical trauma won't even do the job, although sometimes the scent of food ''will''.

This condition may sometimes follow a heavy meal, and hence is often applied to the BigEater. Sometimes it also affects the {{Cloudcuckoolander}}, the ManChild or someone who's BrilliantButLazy.

To some degree, TruthInTelevision: see [[http://en.wikipedia.org/wiki/Narcolepsy Narcolepsy]], a chronic sleep disorder (a dyssomnia) characterized by overwhelming daytime drowsiness and sudden attacks of sleep.

Also, see NotAMorningPerson, where the character ''does'' wake up... just not exactly early and easily. A particularly heavy sleeper may have SleptThroughTheApocalypse.

Compare GoodMorningCrono. See also DeepSleep. Sometimes overlaps with, but should not be confused with, {{Sleepyhead}}.

[[folder: Anime and Manga ]]
* In ''AxisPowersHetalia'', in ''every'' World Conference, Herakles (Greece) is seen calmly and soundly napping on his seat, while all the other nations bitch at each other loudly.
** Canada (Matthew), too. One strip has him speaking to someone else, then they both fall asleep all of a sudden. And his first line ''ever'' in the webcomic was apologizing for sleeping in.
** [[GenkiGirl Seychelles]] somehow manages to fall asleep in the middle of her own character song.
* Beet from ''Manga/BeetTheVandelBuster'' has the ability to stay awake for three days straight, but at the end of the third day, he will fall into an almost comatose sleep from which he cannot be awakened for a full day.
* Ranma Saotome in ''Manga/RanmaOneHalf'' (who on occasion has been known to sleep through full-on fights he participated in).
** This has led to some [[EpilepticTrees wild theories]] on how well him being married to [[{{Tsundere}} Akane]] might work out. Some people sleepwalk, Akane sleep''fights''. [[FetishFuel Think about it]].
** Hilariously used when Nabiki pours cold water on him when he's sleeping to take pictures of his girl self, then adds hot water so he'll turn back to normal. Ranma later wakes up and thinks [[PottyFailure he has peed in his sleep.]]
* Mihoshi in ''Anime/TenchiMuyo''.
* Rock Lee from ''Manga/{{Naruto}}'' is known for sleepwalking for days, keeping a fighting spirit when unconscious as a result of [[TrainingFromHell insane training of reflexes]], as well as being part-time asleep while accidentally drunk-fighting [[ConfusionFu (as either a ruse or really falling asleep in them middle of a fight and waking from incredible reflexes repeatedly, not sure which)]].
** An {{Omake}} features Yamato, Naruto and Kakashi sleeping in camp. Turns out Naruto's hyper even while fast asleep - he not only snores like a buzzsaw but starts dreaming about fighting, up to and including forming a Rasengan. [[ButtMonkey Yamato]] gets no rest at all, but Kakashi (who had the foresight to wear earplugs) sleeps through the whole thing. "That's just not fair."
* Natsumi Tsujimoto from ''YoureUnderArrest''.
* Monkey D. Luffy in ''OnePiece''. In one instance, his crew member Roronoa Zoro bounced off his belly without rousing him. After a fight he will either eat or sleep continuously, and after Ennies lobby somehow taught himself to eat while sleeping to cope.
** We later see that Luffy's brother, Ace, is also a Heavy Sleeper. He once feel asleep while in the middle of eating a feast. The others around him thought he had been poisoned by the food, until he snapped back awake a moment later. After confirming he was just sleeping, and unharmed, he dropped off again mid-conversation.
** Garp remained asleep despite being sliced across the chest by a giant axe. Eneru on the other hand dosed off as his opponent did his best to kill him (stabbing a spear through his head and slicing him in two for starters). Then again, he ''was'' simply showing off his invulnerability.
** Even Zoro, who once slept through a high-seas storm.
* Snoozer in ''Anime/{{Hamtaro}}'', who takes this to extremes in that every time we see him, he's either asleep or talking in his sleep.
** However, he finally woke up for a short time in one episode to confront Bijou, who was crying.
* Carlos from ''GunXSword'' is an old man who is nearly always asleep - even at the controls of his part of the CombiningMecha. He wakes up exactly twice: the first time is at the end of the episode introducing the El Dorado V, and the second time [[spoiler:is in Episode 25, when he wakes up to give a RousingSpeech to his discouraged allies. He stays awake for the final episode.]]
** [[spoiler:He even takes the time to ''introduce himself to the main character'' during the final episode. The guy his group has been traveling with for '''half the series'''.]]
* Nozomi, in ''YesPrecure5'', once launched Coco across the room in her sleep when he tried to wake her up.
* Jiroh Akutagawa from ''ThePrinceOfTennis'' is often sleeping outside of the courts, and it's so bad that Kabaji often has to carry him on his back so he doesn't arrive late to his matches. And there's also Akaya Kirihara, who once fell asleep in a bus and ''crossed all the way from Kanazawa to Tokyo''...
* One of the most common {{running gag}}s of ''SlamDunk'' is how Kaede Rukawa falls asleep anywhere and at any time, unless during practice or games -- once he even fell asleep while ''riding his bike'' to a game and trashed it. And waking him up is NOT an option, since he actually [[UnstoppableRage becomes violent]] [[BerserkButton when he doesn't finish his naps]].
* One episode of ''[[PrettySammy Magical Project S]]'' opens with Ginji, Sasami, and Ryo-Ohki all sleeping through crashing over a cliff into the water and drifting onto an island.
* Ivan Whisky/001 from ''{{Cyborg 009}}''. JustifiedTrope, though: he's a ''very'' powerful [[PsychicPowers telepath and telekinetic]] [[NotAllowedToGrowUp trapped in the body of]] [[GooGooGodlike a baby]], so he logically requires long rest after he uses his power for too long.
* [[GunsmithCats Bean Bandit]]. In the ''Riding Bean'' movie, his partner tries and fails to wake him up for breakfast with a taser applied to his neck. Since Bean is MadeOfIron this only momentarily jolts him. She then takes the pan she just finished frying eggs in and holds it to his face. That works.
* Pop Harukaze from ''Anime/OjamajoDoremi''. One of the principal reasons why she [[CantCatchUp couldn't catch up]] with the other Ojamajos despite her natural witchcraft talents was because the apprentice tests were scheduled during the night, but Pop simply could NOT stay awake no matter how many precautions she took and how many times Doremi and the others tried to wake her up. As a result, she doesn't take her first test until a few episodes into ''Sharp''.
** This is justified since she is [[WakeUpGoToSchoolSaveTheWorld a preschool kid]]. And in another episode, she actually collapsed and fell asleep.
* Chief Komui Lee in ''DGrayMan''. Nothing can wake him when he sleeps, save one thing: mentioning that his sister, Lenalee Lee, is getting married. ([[BigBrotherInstinct He's rather overprotective about her.]])
* Kyou Sohma from ''Manga/FruitsBasket'' can sleep through a hurricane. However, he seems to be an early riser.
** Yuki Sohma also is a heavy sleeper. During a schooltrip, his classmates hardly manage to wake him up. Further, Kyou claims that Yuki's even stronger, when he's drowsy, for he can't control his strength. (Which Yuki proves on the spot.)
* ''[[NegimaSecondSeason Negima!?]]'' have this as a trait to Asuna Kagurazaka. In the series, she actually wakes up early every day for newspaper delivery, making up on weekends (thus, she's more of NotAMorningPerson). [[spoiler: Due to the events in the Magic World in [[Manga/MahouSenseiNegima the original manga]], her fate is to sleep for a century in the Gravekeeper's Palace. [[TearJerker Yeah.]] True to her Heavy Sleeper tendencies, she ends up oversleeping by about 30 years.]]
** In the ''Manga/MahouSenseiNegima'' manga, and later the ''Ala Alba'' OVA, Negi can sleep through quite a bit of manhandling. In chapter 180, he was kicked across a room at least twice and tied up and slung around in a rhythm dancing ribbon without waking up.
*** To top it all off, Negi somehow managed to sleep through that entire fight, even though he was at one point ''knocked unconscious'', recovered ''asleep'', and was ''beaten into unconsciousness again''. He woke the next day achy, bruised, and ''very'' confused.
* Tsukasa Hiiragi from ''Manga/LuckyStar'' habitually wakes up at noon.
* Midnight, a villain in ''Manga/FairyTail'', can ''fight'' in his sleep, and has yet to be depicted awake several chapters into the arc.
* Nemu from ''Anime/HaibaneRenmei'' [[MeaningfulName got her name]] because she even slept in her final dream before emerging from her cocoon. A few of the other Haibane tease her because of this.
* Amae Koromo of ''Manga/{{Saki}}''. To wake her up for the tournament, her teammates set five alarm clocks around her. She slept through every one of them then went on to sleep away the entire day.
* ''SchoolRumble'''s Yakumo has a tendency to fall asleep anywhere, giving her the nickname ''"Literature/SleepingBeauty"''.
** It's also a bit of a DeconstructedTrope, since it ''does'' interfere with her daily chores, like purchasing groceries or doing housework. When ''TheDitz'' of the show is worried and tells you that you've got a problem, it oughta be a serious deal.
* Ryu "The Owl" in ''Anime/ScienceNinjaTeamGatchaman'', to the point where his sleeping on the job has landed him in big trouble more than once.
* In ''Manga/PokemonSpecial'', Yellow is sometimes seen yawning and dozing off. True, overusing her powers '''will''' force her to fall asleep, but you have to wonder how the fook she managed to start napping after she got grabbed and lifted into the air by several Lickitung when she wasn't using said powers the moment before.
** Bayleef's flowery scent lulled her into sleep, and the expression on Bayleef's face shows how random it was. However, she woke up pretty fast that time. Most other times, it's less "asleep" than it is "unconscious".
** A list of examples from ''Pokémon'' just wouldn't be complete without Snorlax. He's the page image for a damn good reason.
* Three characters in ''StrikeWitches'' have this for different reasons. Sanya is simply a night shifter, and thus sleeps through the daily ruckus. Francesca is just lazy, but can be woken up with enough prodding. Erica, however, is lazy and disorganized, and not even her roommate's prodding can get her up.
* In ''Manga/FullmetalAlchemist'', when Ed realizes that his body is probably compensating for Al's, which is still trapped at the Gate, Al remarks that Ed ''does'' fall asleep an awful lot, and wonders if Ed is "sleeping enough for Al's share" too.
* Rem from ''BoboboboBobobo''.
* Morita from ''HoneyAndClover'' makes it a habit to sleep for 48 hours after a job.
* [[CreepyChild Mario]] from ''Anime/MawaruPenguindrum'' is often seen sleeping on a couch at home.
* Ayaka Kisaragi from ''PhantomQuestCorp''.
* Sakura Kinomoto from ''Manga/CardcaptorSakura'' doesn't start as one, but begins to sleep more and fall asleep everywhere [[spoiler: as she starts transforming the Clow Cards into Sakura Cards, which drains her of energy a L O T.]] Similarly, [[spoiler: Yukito/Yue]] takes his up as [[spoiler: his limited life energy starts running out; it's only fixed when Touya gives him his own psychic energy so he won't fade away (And then ''he'' starts sleeping in more...).]]
* In the tournament arc of {{YuYuHakusho}} Yusuke has fallen asleep on the boat ride, not even all the fighting going on when some assassins arrive wake him up, he then spends most of his groups first match still sleeping, he only wakes up when it's his turn to fight.
* It is possible to wake ''OuranHighSchoolHostClub'''s Kyouya Ootori before noon on a day off, but he won't stay that way very long. In one episode, he manages to incompletely wake through Tamaki and the rest of the club inviting him out and forcing him into clothes, drifts off again as they carry him to the expo they wanted to visit, and winds up forgotten by them, sleeping sitting up on a bench until he wakes up alone and with no recollection of how he got there.
* Tigre from ''LightNovel/MadanNoOuToVanadis'' is a rather heavy sleeper. While he can be woken for important matters (like wars), those who try to wake him may end up [[{{ThanksForTheMammary}} groped or even tackled]] while he remains sleeping, and a sword to the mouth, a strong [[{{ArmorPiercingSlap}} slap]] or an equivalent sensation is necessary to wake him.
* Officer Higurashi in ''{{Kochikame}}'' goes through four year hibernation cycles and is only awake one day during the start of every Summer Olympics. The main characters wake him because of his psychic powers to locate wanted criminals.
[[/folder]]

[[folder: Comic Books ]]
* ComicBook/GastonLagaffe, who's also TheSlacker.
* Basile from ''LeonardLeGenie'', waking him up takes heavy-yield explosives or similar violence.
** In one instance, Leonard builds an alarm-clock-contraption that injects Basile with several liters (judging by the size of the syringe) of [[DepartmentOfRedundancyDepartment hyper-concentrated coffee concentrate]], only, once it achieves the intended effect, to tell Basile that it's Sunday and he can sleep in.
* DonaldDuck in one story by CarlBarks where he becomes a fire brigade officer, of all the jobs possible.
* The Caliph from ''ComicBook/{{Iznogoud}}'' spends much of his time contentedly asleep. His advisors know he's worried when he turns in his sleep more than twice a day.
[[/folder]]

[[folder:Film]]
* From film: Bob in ''Film/WhatAboutBob'' sleeps through Leo asking him to wake up, then yelling, then shaking him, then imitating a rooster. Then his small alarm clock goes off and he peacefully awakes.
* ''Film/{{Spaceballs}}'': Prince Valium
* ''Film/{{Meatballs}}'': Marty used to sleep so soundly that one of the running gags of the movie was to move him and his bed into strange places.
* Godzilla. If the climax of ''Film/{{Godzilla 2014}}'' is anything to go by, so much so that [[spoiler: when he gets tired and decides to take a nap after defeating the Mutos, the military initially assumes him to be dead]].
[[/folder]]

[[folder: Folk Lore ]]
* One of the earliest examples was RipVanWinkle, who slept for ''twenty years''.
* Russian folk tales aren't averse to having their larger-than-life heroes sleep for days on end every so often. After all, all that energy that goes into slaying dragons, defeating armies, and performing other mighty deeds has to come from somewhere!
[[/folder]]

[[folder:Literature]]
* ''The Boy of the Three-Year Nap''. He's also BrilliantButLazy.
* We ''never'' see Shari awake in ''Literature/WaysideSchool''.
* [[SubvertedTrope Subverted]] in ''[[Literature/WhoCensoredRogerRabbit Who Plugged Roger Rabbit?]]''. Eddie tussles with a heavy in an art museum, while a lazy security guard snoozes on a nearby fold-out chair, not budging an inch when the two combatants slam each other into the well mere feet from him. [[spoiler: turns out the security guard was faking it, and in fact becomes a key witness that helps Eddie both justify himself to the police and eventually crack the case.]]
* Literature/{{Oblomov}}.
* Greg Heffley in ''Literature/DiaryOfAWimpyKid''. He claims that he's like this because he was born three weeks early [[NoInfantileAmnesia (which he somehow remembers)]]. He's spent the rest of his life up to the present trying to catch up on sleep.
[[/folder]]

[[folder: Live Action TV ]]
* Elliot from ''Series/{{Scrubs}}''. NOTHING can wake her up before she wants to.
** J.D being a sound sleeper is the basis of at least one joke. When Dr Cox and the Janitor are drinking and talking about how much he annoys them, the Janitor reveals that he regularly sneaks into JD's room while he's asleep and moves things around to mess with him. [[spoiler: They move his bed to the hospital parking lot, where he's woken up in the morning by ambulance sirens.]]
--> '''Dr Cox:''' Well, you're clearly in need of help, but goshdarn it I'm not gonna give it to ya. How sound a sleeper you think he is?
--> '''Janitor:''' Well, watch this. ''(kicks the foot of JD's bed)''
--> '''J.D:''' ''(sits up, eyes still closed)'' Wha? ''(falls back)''
* ''Series/StarTrekEnterprise''. Dr Phlox, thanks to his BizarreAlienBiology, hibernates five to six days a year (placing it between weekly episodes if required, which is convenient). On one occasion the crew have to wake him up with an injection. Phlox simply gives a nonsensical diagnosis and collapses back into unconsciousness.
* In the ''Series/MontyPythonsFlyingCircus'' sketch "Strangers in the Night," the husband doesn't fully wake up even when his wife right beside him is being simultaneously propositioned by five men and a mariachi band.
** Ken Clean-Air Systems. "When Ken is in a really deep sleep like this one, the only way to wake him up is to saw his head off."
* Kintaros from ''Series/KamenRiderDenO'' is practically narcoleptic, sometimes falling asleep in mid-conversation and being nigh on impossible to wake. The only thing to consistently rouse him is any word that sounds remotely like "nakeru" (to cry).
* ''Drake and Josh'': Josh claims he's not a heavy sleeper, but a video shows he really is. Megan and her friend take advantage of this and host a web show featuring them doing stuff to Josh when he's asleep.
[[/folder]]

[[folder: Mythology and Religion]]
* OlderThanFeudalism: Kumbhakarna of ''Literature/{{Ramayana}}'' is such a famous Heavy Sleeper that in India, heavy sleepers can often be referred to as the Kumbhakarna. A slip of the tongue botched up a wish for the position of the gods and he instead ended up wishing for eternal sleep, which was then changed to allow him to sleep up to six months in a year. But it goes FromBadToWorse. If at any time he was woken up during his sleep, then he would be doomed to die. Being a giant, it took the stamping and goading ''over 1000 elephants'' across his body, the goading of hundreds of soldiers, the beating of thousands of musical instruments normally to be used ''in the middle of a war'' to get him to wake up.
* {{Jesus}}, who [[http://www.biblegateway.com/passage/?search=Mark+4:37-41 was asleep in the stern of a fishing boat during a furious squall]]. As the storm raged on, the waves threatened to capsize the boat, and His panicked disciples (experienced sailors themselves) woke Him up. Jesus proceeded to tell the storm to be quiet, ''and it listened''.

* The safecracker in ''Pinball/JudgeDredd'', who sleeps through machine gun fire and a tank crashing into his room.
[[/folder]]

[[folder: Video Games ]]
* The ''Franchise/{{Pokemon}}'' Snorlax is notorious for doing two things: sleeping for months at a stretch and [[BigEater devouring entire islands worth of food when it's awake]]. The first game has a BrokenBridge of one falling asleep on a road and blocking all traffic from either direction because nobody can get it to move.
** Snorlax ''appears'' to be loosely based off of a ''[[TabletopGame/DungeonsAndDragons D&D]]'' monster known as the Tarrasque. In one of the sourcebooks (the 2nd edition Monstrous Manual, I believe) it is described as sleeping for years on end, then waking up ''extremely'' hungry and eating everything for several miles. Including the odd civilization or two. It isn't easy to wake up, but if you do... time to get out a clean character sheet.
** And, to a lesser extent, Erika (the Grass-type Gym leader from the [[VideoGame/PokemonRedAndBlue first generation]]) is implied to be mildly narcoleptic.
** Caitlin of the Unova Elite Four is this in [[VideoGame/PokemonBlackAndWhite Black and White]].
* In ''[[VideoGame/MarioAndLuigiBowsersInsideStory Mario & Luigi: Bowser's Inside Story]]'', Luigi sleeps through a meeting ''and'' an attack from Bowser. He only wakes up when Bowser inhales him after breaking into Peach's castle for a second time. (Though given that he was scratching and moving around, it's likely he was only pretending to be asleep to avoid having to fight Bowser).
** General White in ''VideoGame/PaperMarioTheThousandYearDoor'', who first has been followed across the world map, Mario missing him by seconds, then woken up by Mario's attacks to get permission to use the cannon at Fahr Outpost. Funnier yet, he was trying to find Mario the entire time...
** Luigi is once again a heavy sleeper in ''VideoGame/MarioAndLuigiDreamTeam''. This time it serves a plot and gameplay purpose: the story involves Mario and Luigi venturing into the Dream World by Luigi falling asleep on special beds and Mario jumping into his dreams through a portal. Starlow can tickle his nose, pull on his mustache, and even knock his hat over his eyes in order to changes things in the dream, but Luigi will never once wake up until his brother returns to Pi'illo Island.
* Laharl from ''VideoGame/DisgaeaHourOfDarkness'' is implied to be a heavy sleeper. When he wakes up from his two year "nap" at the beginning of the game (after Etna tries bludgeoning him with a variety of weapons), he doesn't seem too fazed about it, and one of his nameless henchmen mention that it's pretty typical for him. Furthermore, he comments that he was only expecting to be asleep for ''ten days''. [[spoiler: But it turns out that the reason he slept for two years was he was poisoned.]]
** In "Etna Mode" of the PSP port, Etna is unable to wake him until she ''actually kills him''. [[spoiler:Or so it seems.]]
* [[RealityWarper Yukari Yakumo]] of ''VideoGame/{{Touhou}}'' spends about three quarters of her time sleeping, at the very least. Just as well for the rest of characters, because when she's awake she's a nigh-omnipotent TricksterMentor (or just a trickster depending who you ask) who loves messing with people.
** In many fanworks, Hong Meiling, the door guard of the Scarlet Devil Mansion, is like this, which often incurs the wrath of [[NinjaMaid Sakuya]] and her [[KnifeNut knives]]. In canon, however, when Meiling wakes up, she shows no mercy to whoever tries to get into the mansion without the permission of her mistresses.
** [[TheSlacker Komachi Onozuka]] is also often portrayed like this, due to her laziness directly causing the Incident of ''Phantasmagoria of Flower View''.
** Yuka also sometimes gets portrayed as this, as you fight her [[SequentialBoss first]] when she hasn't properly woken up. And yes, it is easy to lose to someone who is still asleep.
* The protagonist of ''[[VideoGame/CustomRobo Custom Robo: Battle Revolution]]'' starts off as a heavy sleeper, only ever making it out of bed in the morning if his landlady comes into his apartment to wake him up or his phone goes off. He does improve over the course of the game, though.
* Played for dark laughs in ''{{Overlord}}'' with Oberon, the FallenHero of Sloth. Tiring of a life of fighting, he was convinced to not get involved with the war between [[ElvesVsDwarves the Elves versus Dwarves]], choosing instead to take a long rest upon a tree. This eventually led to him getting entangled with the tree's roots and his nightmares corrupting the forest.
* Forde from ''VideoGame/FireEmblemTheSacredStones'' is such a heavy sleeper that he takes naps in the middle of battles. This is revealed in [[CrashIntoHello his support conversations]] with [[SugarAndIcePersonality Vanessa]], who naturally assumed he was wounded and needed help. When told how irresponsible he's being, his excuse is that it's a just ploy to draw enemies close for an ambush.
** He's also GenreSavvy enough to specially outfit his horse saddle so he can sleep on horseback and not fall off.
* General Haar from VideoGame/FireEmblemTellius.
* The Player Character in ''KnightsOfTheOldRepublic'' starts the game by managing to remain asleep through a [[RedAlert General Quarters call]], a pitched space battle and the crippling of their ship. They only finally awake when the StarTrekShake gets bad enough to hurl them out of bed.
* Talon in ''Franchise/TheLegendOfZelda'' series. He's usually found sleeping, in which case a cucco or a megaphone are needed to wake him up.
* In ''YggdraUnison'', after [[spoiler:apparently being killed in the battle for Karona and then reincarnating as usual]], Nessiah sleeps through ''the entire war he wanted to take advantage of'' unless you find his [[SecurityBlanket lost spellbook]], upon which he will immediately wake up (and be [[NotAMorningPerson rather disgruntled about it]]). Seeing as finding the Revelation can be a massive GuideDangIt, [[AntiFrustrationFeatures the game developers are kind enough]] to make Nessiah ''stay'' awake for all subsequent playthroughs once you've found him.
* Annie of ''VideoGame/{{Atelier Annie|Alchemists of Sera Island}}''. The game opens with she is being hauled across ''a mountain'' and ''an ocean'' by her grandfather's homunculi, during which she doesn't wake up at all. When she arrives at Sera Island, she is still sleeping, which causes her FairyCompanion Pepe to resort to some mild violence to wake her up (and he has to do it again once or twice throughout the game).
* [[Franchise/MetalGear Solid Snake]] won't wake up unless you point a gun at his head... no, wait... Solid Snake will wake up ''the instant'' you point a gun at his head.
* Senel from ''VideoGame/TalesOfLegendia'' can sleep though an earthquake that threw him off his bed on to the floor... of the first floor. His bed was on the '''second'''.
** This was actually a RunningGag in the Character Quests, where the party members would take turns trying to wake him up. At one point, Will resorted to ''kicking him in the head'' and he still didn't stir.
* In ''VideoGame/TalesOfDestiny'', [[TheHero Stahn Aileron]] is a notoriously heavy sleeper, to the point his sister Lilith developed a ''special attack'' just to wake him up. After he married Rutee, they had a son named Kyle (protagonist of the second game) who inherited this from his father. Rutee obtained her sister-in-law's technique for "waking up the boys": making a racket with pots and pans... right next to their heads.
* The goal of the online game ''VideoGame/{{Grow}} [[http://www.eyezmaze.com/eyezblog_en/blog/2011/01/grow_cannon.html Cannon]]'' is to wake up the little guy after he [[RingRingCRUNCH smashes his alarm clock]]. It's harder than you might think, as the guy turns out to be able to sleep right through being doused by water, stepped on by a giant foot, electrocuted by a magic staff-wielding man, run over by a train, and being ''blown up into a crater by a rocket''.
* A minor female vendor [=NPC=] in ''VideoGame/{{Solatorobo}}'' spends the entirety of the game dreaming of money and [[TalkingInYourSleep talking about it in her sleep]]. She even manages to sleep through a kaiju attack and the final large scale battle at the climax of the game.
* It's even a trait in ''TheSims3''. Sims with it can sleep through nearly anything: radios, fires, burglaries, crying babies....
* Dozy in ''[[VideoGame/{{Dizzy}} Fantasy World Dizzy]]'' falls back asleep when you wake him up and talk to him. You can then knock him into the water, and he'll still be asleep.
* [[{{Hikikomori}} Madotsuki]] from ''YumeNikki'' only does three things in her daily life: play video games, write in her dream diary, and sleep. Almost the entire game takes place [[DreamLand in her dreams]].
[[/folder]]

[[folder:Visual Novels]]
* Nayuki in ''VisualNovel/{{Kanon}}''. The VisualNovel explains the psychological reasons behind her behavior: [[spoiler: her unhappy memories of Yuuichi rejecting her confession of love to him, all those years ago]]. This leads to some amusing [[NonSequiturThud non-thudding non-sequiturs]] delivered in her barely-ambulatory state.
** This aspect of her character is used for both of her forms in ''EternalFighterZero''. She has a "sleepy" form that parodies the DrunkenBoxing fighting style, and an "awake" form that unleashes her huge alarm clock collection for her Final Memory attack.
* Suzu Suzuki from ''KatawaShoujo''. This is justified, since she has narcolepsy and that's why she is in Yamaku to start with.
* Riki, the protagonist of ''VisualNovel/LittleBusters'', who also has narcolepsy.
* Shiki from ''VisualNovel/{{Tsukihime}}'' is one. Its hard to believe that he is [[spoiler:(at least subconsciously) a highly trained assassin.]] Hisui, his personal {{maid}}, doesn't even bother trying to wake him in the morning due the impossibility of such task.
** It's worse that both Hisui and [[OurVampiresAreDifferent Arcueid]], on the occasions they first see Shiki asleep, briefly worry that he'd actually ''died'' some time in the night. [[spoiler:Worst of all, in at least one route, that's not as implausible as it sounds...]]
* Kyoko Ashihara from ''{{Crescendo}}'' -- so much that she's seen sleeping in the cover of the game itself, [[LapPillow on the lap of her friend Kaho]]. The protagonist, Ryo, also seems to skip classes frequently so that he can sleep in SchoolNurse Kaori's office.

[[folder:Webcomics]]
* Agatha in ''WebComic/GirlGenius''. Early on she was even more competent as a builder of mad science devices in her sleep and the most astonished one when those devices show up later! As well as known for building and shooting death rays in her sleep - making huge holes in mountains in the process. Oops!
* Tiffany from ''WebComic/{{Precocious}}'', when she's not destroying things or doing random acts of chaos.
* X of ''AMagicalRoommate'' decided that sleeping every night was inconvenient, so she found a way to stay awake for months at a stretch and then hibernate. It takes a magic potion to wake her up before she's ready once she decides to sleep.
* Ally of ''{{Shiniez}}'' is never shown sleeping eloquently; she sleeps with her mouth open and snores like an animal. Her bed partner Lisa kisses her and gets out of bed without her even stirring.
[[/folder]]

[[folder: Web Original]]
* Bill and Morgan in ''WebVideo/CommodoreHustle''. Morgan will not be roused by bullhorns in his face, yelling, or shaking - the only reliable way to wake him is to uncap a sharpie in his presence. Bill is much the same; he can only be woken by ninjas, or Morgan holding his nose.
** According to the season one DVD commentary, this is more or less truth in television. There are only three ways to reliably wake the real Bill: hold his nose, roll him over a full 360 degrees, or push him out of bed.
* In the ''HappyTreeFriends'' episode "Easy For You To Sleigh" Lifty and Shifty have entered Flippy's house and attempt to rob him while he's asleep in a chair, one of them accidentally turns on the tv and a bugle horn plays on the program, they break a few things, and bang some cymbals he never even stirs, they then proceed to steal his stuff and tie him up, only after stealing his plate of cookies and knocking a crumb on the floor does he wake up.
* According to Lewis's tumbr his character is this here is the link http://atopfourthwall.tumblr.com/post/85616955743.

* ''SpongebobSquarepants''' friend Patrick.
* Ahito from ''GalactikFootball'' will happily fall asleep ''in goal''. This does not necessarily stop him from saving the ball when he needs to.
* A scene in ''FamilyGuy'' has a team of deaf athletes forfeiting the Special People's Olympics because they slept through the alarm.
* Buster Baxter in ''WesternAnimation/{{Arthur}}''.
* Bill Dauterive in ''KingOfTheHill'' in at least one occasion. During when Cotton and Didi's baby was crying all night disturbing the neighbors, Bill was still sleeping even with a squirrel entering his opened window.
* Heloise on ''{{Jimmy Two-Shoes}}''. Samy's repeated attempts to wake her only results in her having DreamSequences about Jimmy.
* ''XMenEvolution'' has Kurt, who not only spends almost an episode asleep when he gets the flu, but also ''teleports'' in his sleep every time he sneezes. This leads to him and Kitty popping up all over town in their pajamas. When he finally wakes up, he thinks it was AllJustADream... at least until Kitty starts whaling on him with a pillow.
* As in his NewspaperComics incarnation, Garfield of ''GarfieldAndFriends'' is also a textbook Heavy Sleeper. Nothing can wake him up - unless you're trying to hide [[BigEater food]] from him.
* In the Season 2 finale of ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', the palace is captured by [[EmotionEater Queen Chrysalis and her changelings]], who toss [[BoundAndGagged Princess Celestia in a cocoon]] and proceed to run amok in Canterlot complete with explosions and ponies running screaming. And Princess Luna sleeps through the whole thing.
--> '''Princess Luna:''' Hello everypony. Did I miss anything?
* Mr. Von Fuzzlebutt in ''WesternAnimation/LittlestPetShop2012'', who can only be woken up on his own. He is even put in the middle of a musical number without so much as a wiggle.
* Dexter's father in ''WesternAnimation/DextersLaboratory'', who combines this with sleepwalking. Sirens, explosions, electrocution, and strange chemicals do not deter his sleep at all. He also thinks he's a light sleeper.
