** In ''[[Manga/JoJosBizarreAdventureTheJOJOLands The JOJOLands]]'', Paco Laburantes' Stand, The Hustle, gives him advanced control over his muscles, letting him grab things with any part of his body. It comes in handy when stealing stuff, as he can grab things without leaving fingerprints on them, and is very useful in a fight, as he can use his muscles to grab his opponent's limbs or weapons or grab nearby objects to use as weapons with a touch.

** In ''[[Manga/JoJosBizarreAdventureTheJOJOLands The JOJOLands]]'', Paco Laburantes' Stand, The Hustle, gives him advanced control over his muscles, letting him grab things with any part of his body.

* Practitioners of the Hercules Method in ''ComicBook/TheStrangeTalentOfLutherStrode'' take this up to 11. The protagonist in particular can literally leap tall buildings in a single bound, essentially [[FeelNoPain feel no pain]], regenerate from bullet wounds in seconds and punch ordinary people/highly trained mercenaries hard enough to reduce them to blood spray and body parts.

* ''Anime/MobileSuitGundamWing'' has Heero Yuy, who could control his brainwave activity.

** The mutant known as Courier from ''ComicBook/Gambit1999'' has the power of 'endopathy', which lets him communicate with his own body's cells. Among other things, he can change gender, tune his body to evade mutant-gene scans and regenerate from injuries (although he is subject to [[ShapeshifterBaggage conservation of mass]]).

** Eddie learns in ''ComicBook/Venom2021'' that, after a power upgrade, he has total control over his physical form. This allows him to [[FromASingleCell self-ressurect from his remains]], use UninhibitedMusclePower and ignore the damage that ensues because he can [[HealingFactor immediately patch himself up]], and extend his internal organs such as intestines and nerve endings to grapple with.

* In ''Film/ScannersIIITheTakeover'', Alex learns how to control his heartrate from a Buddhist monk. He later uses it to stop his heart to avoid being killed in a hospital bed by one of his sister's assassins before WakingUpAtTheMorgue.

* In the ''Literature/ModestyBlaise'' novels, Modesty has a collection of body-control techniques she learned from a HermitGuru that allow her to do things like shed negative emotions or put them aside to deal with later, slow her metabolism if she's trapped and exposed to the elements, and put herself into a coma-like trance. In ''The Night of Morningstar'', she demonstrates an ability to control individual muscles with remarkable precision, first as a party trick and then [[spoiler:after being injected with a sedative by the villains, to squeeze the injected fluid back out through the injeciton puncture]].

* ''TabletopGame/{{Shadowrun}}'': The stock in trade of the Adept, who uses KiManipulation or MagicalEnhancement to control their bodies in extremely minute ways. Depending on what you spend your [[PointBuildSystem Power Points on]], Adepts can do anything from bending their limbs the wrong way, balance on the head of a pin, [[TheNeedless go days without food, water or sleep]], regenerate from wounds incredibly quickly, super-charge their physical attributes, or fine-tune their vocal chords to perfectly mimic any sound.
* ''TabletopGame/StarWarsD20'' allows trained Jedi to enter a hibernation trance that drastically reduces their need for air, water and food.

** The Pillar Men from ''[[Manga/JojosBizarreAdventureBattleTendency Battle Tendency]]'' take this ability to [[BodyHorror sick]] [[LovecraftianSuperpower extremes]], being able to manipulate their bodies in various ways, from using their rib cages as bear traps to using their blood vessels as tendrils that spit boiling blood.

* Wim Hof is able to regulate his body temperature to such an extent that he can climb Mt. Everest and run marathons in freezing winter. Wearing nothing but shorts.

* ''WebOriginal/AcademyOfSuperheroes'':

Can be a subtrope of {{Biomanipulation}}; here, the manipulation is strictly to one's own body.

* The BigBad from ''Anime/NinjaScroll'' mastered this to a deeply exaggerated level; he can control every single cell of his body and [[FromASingleCell regenerate from any level of damage short of total annihilation]].
* Medaka of ''Manga/MedakaBox'' is able to consciously control her reflexes and sundry other biological processes.

* ''Manga/JoJosBizarreAdventure'':

** In ''[[Manga/JoJosBizarreAdventureTheJOJOLands The JoJoLands]]'', Paco Laburantes' Stand, The Hustle, gives him advanced control over his muscles, letting him grab things with any part of his body.
* This is the core element behind ''Enbu'', or Monkey Martial Arts in ''Manga/{{Toriko}}''. It involves unifying literally every single cell in your body for a single purpose. Doing so can enhance your abilities far beyond the norm and allow traversal through otherwise deadly environments.
* ''Manga/JujutsuKaisen'': Flowing Red Scale is a Blood Manipulation technique that can be used to modify bodily parameters to achieve drastic physical improvement, while this usually runs the risk of causing blood clots, thrombosis and other systemic issues. Choso's HealingFactor can severely mitigate (though not nullify) potential internal damage, allowing him use to it with far greater frequency.
* Ikki Kurogane from ''Literature/ChivalryOfAFailedKnight'' can do things like manually move the muscles of his heart to make it beat after it was stopped by Amane or understand every muscle inside his body and even able to count the dust on his skin.
* ''Literature/ACertainMagicalIndex'': Seria Kumokawa can use autohypnosis to block out pain from injuries, [[spoiler:including having an eye removed]].
* Ryoko in ''Anime/TenchiMuyo'' (OVA continuity) is ImmuneToDrugs, thanks to being a genetically engineered superhuman. But only when she ''wants'' to be immune. Since Ryoko [[HardDrinkingPartyGirl loves getting drunk]], she turns this ability "off" ''a lot''.

** [[ComicBook/Robin1993 Tim Drake (Robin III/Red Robin)]] can slow his heartbeat to fake death or slow blood loss and can continue listening to his surroundings for about a minute after being drugged into unconsciousness if he has a bit of warning.
* Issue #10 of Creator/WarrenEllis' ''ComicBook/GlobalFrequency'' is a 20-page fight between two guys who can do this. It is predictably messy.
* Axel Brass (an {{Expy}} of Literature/DocSavage) in ''ComicBook/{{Planetary}}'' has these powers.
-->'''Brass:''' I eliminated my need for food and sleep in 1942, stopped aging in '43, and learned to close wounds with the power of my mind in '44.
* In ''ComicBook/{{Stormwatch}}: Team Achilles'' (#23 or so), Baron Chaos fools ComicBook/TheAuthority's appallingly high-tech scanners into thinking he's in a coma.

** Apocalypse, the ''ComicBook/XMen'' villain, has this down to the molecular level, making his VoluntaryShapeshifting exceptionally powerful and even allowing him to rearrange body parts so fast that [[SuperSpeed Quicksilver]] can't dodge his attacks.
** Most mid-to-high-level Marvel martial artists have been shown to have this ability, mostly for healing and faking death. ComicBook/{{Daredevil}} can speed up his healing via meditation as can ComicBook/{{Elektra}}, ComicBook/IronFist and ComicBook/ShangChi.
** Master Izo was able to feign death by slowing his heartbeat to almost nil.
** Noh-Varr, of the Creator/GrantMorrison comic ''Marvel Boy'', has a technique for rerouting pain signals to his auditory cortex thus literally turning pain into music. There is also the White Run technique from issue #4.
** The mutant known as Courier has the power of 'endopathy' which lets him communicate with his own body's cells. Among other things, he can change gender, tune his body to evade mutant-gene scans and regenerate from injuries (albeit he is subject to conservation of mass.)
** Mystique, primarily known as a mutant shapeshifter, has shown the ability to move vital organs to safer locations in order to survive getting shot and play dead.
** Sage of the X-Men has conscious control over her body functions thanks to her "computer brain" mutant ability.

* An OldMaster during the [="=]Forever[="=] story arc in ''ComicBook/{{Powers}}'' could do this.
* The Ayakami ninja clan in ''ComicBook/{{Empowered}}'' know a special technique that allows them to suppress pain. It's effective enough that fighting them is pretty much like fighting zombie ninja.
* ''ComicBook/{{MINDMGMT}}'': among the various secret agents with PsychicPowers in this series are the Immortals, whose control over every one of their cells means they can close wounds, ignore pain, and even develop gills when submerged at the bottom of a river. None of them can die, [[AndIMustScream no matter how much they want to]].

* Practitioners of the Hercules Method in ''ComicBook/TheStrangeTalentOfLutherStrode'' take this up to 11. The protagonist in particular can literally leap tall buildings in a single bound, essentially [[FeelNoPain feel no pain]], regenerate from bullet wounds in seconds and punch ordinary people/highly trained mercenaries hard enough to reduce them to blood spray and body parts.
* ''Creator/ValiantComics''

** And Roku: "For the first time I felt my bones... every muscle, every tendon... for the first time I felt every follicle... every cell... for the first time... I felt complete control."

* Izuku in ''Fanfic/TotalCommand'' realizes several years late that he has a Quirk in the form of full control over his body. While initially subconscious, such as his throat muscles working to vomit up the Sludge Villain, once Izuku becomes aware of it, he starts consciously producing more hemoglobin and HGH (a growth hormone) while constantly keeping his heartbeat optimized.
* This on crack is basically how active use of the basic Predator Trait seems to work in ''WebAnimation/HoloChronicles'', though different people use it in different ways. For a few examples, Gura allowing her instincts to take over allowed her to enhance her strength and speed, Okayu enhances both her physical strength and stealth capabilities, and Botan amplifies her sensory capabilities to the point of apparent precognition.
* Xander Harris in the Journeyverse series (a ''Series/BuffyTheVampireSlayer'' fanfic by Tenhawk) has an increasingly thorough mastery of his body; he is able to pump more blood to his brain to stay conscious under high-gee maneuvers and heal wounds faster via meditation. He is even able to force a Goa'uld symbiote out of his body by making it an unforgivingly hostile environment (he reversed the flow of carbon dioxide into his blood, pumped out toxic amounts of adrenaline, stopped his kidneys -- all while keeping his brain alive just long enough.)

* ''Film/GodzillaKingOfTheMonsters2019'': The film heavily implies that it's no coincidence Mothra's cocoon hatches at the onset of King Ghidorah's takeover. The novelization confirms that her metamorphosis speeds up because she senses that Ghidorah has started ravaging the world.

* The ability to consciously slow down one's own heartbeat to fake death is used to escape imprisonment by Film/JamesBond in ''Film/DieAnotherDay''.
* ''Film/OurManFlint'': Derek Flint could use meditation to put himself into a state of suspended animation that was indistinguishable from death (no pulse or breathing).
* ''Film/TheIncredibleHulk2008'' movie has Banner learning to suppress his transformations with breathing and meditation. [[spoiler:It was also used later to trigger a controlled transformation]].
* Dieter Tautz, a yoga master in the film ''Film/{{Scanners}}'' is said to be capable of controlling his heart rate and several other usually uncontrollable body functions. However, Cameron's biokinetic powers prove too much even for him to control.
* ''Film/ScannersIIITheTakeover'': Alex learns how to control his heartrate from a Buddhist monk. He later uses it to stop his heart to avoid being killed in a hospital bed by one of his sister's assassins before WakingUpAtTheMorgue.
* The Bride from ''Film/KillBill'' can do some neat tricks thanks to her kung fu training: she can slow her heartbeat to make it seem like she's in a coma, and estimate the passage of time from the changes in the lines of her palms.
* In the third ''Film/{{Riddick}}'' movie, the desert dogs pursue the wounded Riddick, and he hides underwater in a pool of poisonous water. He slows down his own heartbeat to calm down and go unnoticed.
* Storm Shadow did this in ''Film/GIJoeRetaliation'' to fake a flat-lining heartbeat and escape captivity.
%% Needs context * ''Film/{{Lucy}}'': The protagonist gains this as part of her first power-up.

* The Bene Gesserit of ''Literature/{{Dune}}'' have such utter self-mastery that they can create and negate poisons inside their bodies, stop their hearts at will and choose to let themselves age (albeit slowly) only because a cult of eternally-young women would be socially destabilizing.
* ''Literature/SecondApocalypse'': Dunyain monks have extremely high control over their bodies and minds. They have nearly superhuman physical abilities and almost total mastery over their expressions, making them perfect actors. They have also had their passion bred out of them, so that it does not get in the way. All of their training and breeding is bent on removing instinct, emotion, and other forces that determine their actions, so that they can become beings of pure will.
* The Envoys from Creator/RichardKMorgan's ''Literature/TakeshiKovacs'' series are all capable of manipulating their bodily functions. The main reason being that Envoys BodySurf more often than most people, both as a means of interstellar travel and [[BodyBackupDrive coming back from the dead]], and the techniques help them acclimatize to new sleeves and ensure they're ready to kick ass regardless of their body's condition. In ''Broken Angels'', Takeshi Kovacs [[spoiler:has a neural inhibitor remote attached to his skull programmed to kill or sedate him if he experienced any strong emotion. Willing himself completely calm, he rips it out of his head without triggering its responses.]]
* Creator/CoryDoctorow's story ''[[http://www.salon.com/technology/feature/2002/08/28/0wnz0red/ 0wnz0r3d]]'' features computer hackers that figured out how to hack their own bodies. Among other things, they spawn custom T-cells that infect HIV-positive people and cure them.
* Tofu from ''Literature/SuperMinion'' has swarms of {{Nanomachines}} under his control. They self-destruct if he sends them outside his body, but inside his body he can use them to reconstruct his body on the fly and manually control the few biological functions he actually needs.
* Almost every book by Creator/PoulAnderson features biofeedback. ''The Boat of a Million Years'' has Nornagest, an immortal who learned meditation and biofeedback arts that allowed him to consciously halt blood-flow to his wounds and accelerate his own already enhanced healing.

* The Monastics from ''Literature/TheActsOfCaine'' books have their Control Disciplines.
* The Spine Assassins of the ''Literature/DeepgateCodex'' books are "Tempered" into emotionless killing machines who can suppress pain responses and accelerate their metabolisms for brief bursts of super speed.
* Used in the ''Franchise/StarWarsExpandedUniverse''. From putting yourself into a trance that allows you to seem dead, to Vergere's 'Art of the Small' which she used to alter her own bodily chemistry until [[SwissArmyTears her tears could inflict or cure diseases if she wished]], it's all over the place.
* In the ''Literature/SymphonyOfAges'' books by Elizabeth Hayden, Achmed the Snake can change his heartbeat to match the rhythm of anyone possessed by a demon or from the island of Serendair in order to track them across long distances.
* Creator/AnneMcCaffrey's ''Dinosaur Planet'' books feature "Discipline": a full-featured body-control/pain-control/emotion-control/adrenal-control technique that many of the characters practice.
* Creator/UrsulaKLeGuin's ''Literature/TheLeftHandOfDarkness'' has the ''dothé'' discipline which enables practitioners to deliberately unleash [[http://health.howstuffworks.com/human-body/bodily-feats/adrenaline-strength.htm hysterical strength]].
* In Creator/JasperFforde's ''Literature/ShadesOfGrey: the Road to High Saffron'', [[spoiler:Jane Grey]] can consciously control [[spoiler:the size of her pupils]], which means that unlike everyone else in the novel's {{dystopia}}n setting, [[spoiler:she can see in the dark]].
* The Red Monks from Tim Lebbon's ''Dusk'' and ''Dawn'' have this talent alongside focused berserker rage/hate.
* The protagonist from Creator/BenBova's ''Orion'' has complete awareness and control of every synapse in his nervous system.

* ''Literature/TheDresdenFiles'': Harry Dresden learns a few techniques from his interactions with Lash: mostly pain suppression but also uses yogic contortionist techniques to escape the thorn manacles in ''Literature/ProvenGuilty''.
* The protagonist of the ''Literature/IronDruidChronicles'' is able to draw energy from the earth to heal injuries, purge toxins and negate pain.
* Remo Williams of ''Literature/TheDestroyer'' uses the principles of Sinanju and its total body awareness to do everything from regulate his body temperature to expel poisons from his body.

* The character of Emma Anyanwu and her descendants in Octavia Butler's ''Literature/{{Patternist}}'' series can control their bodies at a cellular level. Anyanwu can alter her own DNA and appearance at will, while her descendants are able to heal or injure the bodies of themselves and others. However, it takes time and practice to learn to do this properly, and every change they make in a body has to be understood and visualized.
* Onyesonwu, the protagonist of Nnedi Okorafor's ''Literature/WhoFearsDeath'' is a shape-shifting sorceress who has this as a secondary power.
* The protagonist of Ayize Jama-Barrett's ''The Liminal People'' is extremely gifted in {{Biomanipulation}} and can heal, harm or overhaul the bodies of others almost as easily as he does his own.
* The eponymous protagonist of ''Literature/TheConfessionsOfPeterCrossman'' had this ability in one of the earlier stories.
* The empowered characters in ''Literature/TheAccidentalSuperheroine'' control their bodies on a molecular level, which gives them RubberMan and other shapeshifting powers, as well as seeming CompleteImmortality.
* Aegon Morgenstern from the Doctor Dire books by Andrew "Lost Demiurge" Seiple uses self-hypnotic biofeedback techniques to FeelNoPain.

* ''Literature/TheImmortals'': Daine can control her heartrate with wild magic and meditation. However, accidents can occur, like when in ''Wild Magic'', [[spoiler:she was trying to contact dolphins telepathically in meditation and decided her heart was too loud -- so she accidentally ''stopped it'']].
* Chad Taylor from ''Literature/SuperPowereds'' possesses this as a superpower. He uses it for [[EmotionSuppression complete control over his emotions]], ingesting massive amounts of minerals and processing them into his body to give himself [[SuperStrength super strength]] and [[SuperToughness toughness]], manipulating his muscles and nerves to give himself [[SuperReflexes speedster-level reflexes]], recalling all events recorded in his brain and boosting its performances granting him [[PhotographicMemory eidetic memory]], a SherlockScan and immunity to telepathy... As well as a few more techniques, such as his blood-based water saw.
* In ''Literature/TheSpiritThief'', mastering one's own spirit allows humans to perform various feats of superhuman strength and toughness, such as shrugging off weights that should crush them and {{No Sell}}ing blades and arrows with contemptuous ease.

* In ''Literature/ANightInTheLonesomeOctober'', meditating in a zen garden is one of Larry Talbot's techniques for maintaining self-control during his werewolf transformations.
* In the ''Literature/ModestyBlaise'' novels, Modesty has a collection of body-control techniques she learned from a HermitGuru that allow her to do things like shed negative emotions or put them aside to deal with later, slow her metabolism if she's trapped and exposed to the elements, and put herself into a coma-like trance. In ''The Night of Morningstar'', she demonstrates an ability to control individual muscles with remarkable precision, first as a party trick and then [[spoiler:after being injected with a sedative by the villains, to squeeze the injected fluid back out through the injeciton puncture]].
* In the ''Literature/{{Discworld}}'' novel ''Literature/ReaperMan'', Windle Poons has to assume direct control of all his bodily functions when he becomes a zombie. It's not just that he's ''able'' to control them, it's that he ''has'' to. The reason for the ZombieGait is apparently that they have to work out how leg muscles actually ''work'' from first principles. He can't eat because he has no idea how his digestive system operates.
* In the ''WesternAnimation/AvatarTheLastAirbender'' novel ''Rise of Kyoshi'', one of Avatar Kyoshi's teachers known as Tieguai The Immortal extended his lifespan thus:
-->"With the right mental focus, you could take an inventory of your own body and place each little piece that's not where it should be back into the correct order."

* ''Series/TheBionicWoman'' (1970s) episode "Biofeedback", which has a guest character (Darwin Jones) who could use biofeedback to control his own bodily functions.
* ''Franchise/MarvelCinematicUniverse'':
** ''Series/AgentsOfSHIELD'': Once it has regained some strength, Hive demonstrates the ability to control its host's tissue for various purposes, releasing it as a cloud of individual cells. On other Inhumans, these cells infect the brain and make the Inhuman loyal to Hive above all else. With normal humans, it's to aid in feeding. Hive describes its own body as "every cell working together for a common purpose".
** ''Series/Daredevil2015'':
*** Stick uses meditation to heal injuries and live longer than he has any right to.
*** Nobu of the Hand can slow his heart rate and lower his body temperature, and his dialogue indicates that this is standard tactic for the Hand.
* In the ''Series/StarTrekTheOriginalSeries'' episode "[[Recap/StarTrekS1E3WhereNoManHasGoneBefore Where No Man Has Gone Before]]", the newly psychic Gary Mitchell can control his heart rate.
* In one episode of ''Series/TheIncredibleHulk1977'', the main guest character was a cop who was also involved in martial arts, who could turn his pulse off during meditation. He and his sensei tried to help David to use meditation to suppress the change.
* In ''Series/TheInvisibleMan'' series pilot, Darien is having trouble consciously controlling his [[AppliedPhlebotinum Quicksilver gland]], which is activated by adrenaline. This is hilariously shown when he tries to spy on a soldier and a nurse getting it on and reappears at an inopportune moment (which the soldier did not appreciate). His brother teaches him some basic yoga techniques to allow him to not only appear and disappear at will but to also selectively make parts of his body invisible. He also learns to secrete Quicksilver on small objects, making them temporarily invisible as well. This is brought up in a later episode where his brother's [=RNA=] is injected into the gland, allowing him to temporarily take control of Darien's body ([[ArtisticLicenseBiology don't ask]]). He also has trouble controlling the gland at first.

* Underplayed drastically on ''Series/{{Seinfeld}}'', where "Master of your Domain" simply meant the ability to resist the urge to masturbate. [[AllMenArePerverts None of them can hold out long]]. [[AllWomenAreLustful Not even Elaine]].
* ''Series/TwinPeaks'': Agent Dale Cooper exhibits numerous feats of mind-body coordination over the course of the investigation into Laura Palmer's murder, most obviously his "[[ItMakesJustAsMuchSenseInContext throwing rocks at bottles to find leads]]" detective style and his survival of a gunshot wound by [[ShoutOut keeping fear from his mind.]]

* NZT users in ''Series/{{Limitless}}'' demonstrate this, particularly [[spoiler: Rebecca]]. When she needed to come work injured and on NZT, she simply decided to just stop feeling the pain so she wouldn't flinch if anyone bumped into her wound.

* Fiona hin'Connaill of the podcast web serial ''Podcast/MetamorCity'' is an "egoist" i.e. a psychic whose power is the ability to control and/or enhance any of her physical traits at will. So is Miriam.

* ''TabletopGame/PsionicsTheNextStageInHumanEvolution''
** Biofeedback grants espers conscious control over their own bodies, for the purpose of healing damage, purging toxins, and surviving without food and water for much longer than a normal human when necessary.
** Somakinesis also applies. It grants espers that ability to consciously increase their strength and speed for short periods of time, as well as preserving muscle tissue.
** Somakinetics can also just decide to have their unarmed attacks deal lethal damage or add extra dice to their unarmed damage rolls if they feel like it.
** The book describes scrying as the act of turning your psychokinesis inwards to expand your own consciousness.
* Metabolism Control in ''TabletopGame/{{GURPS}}'' allows the character to control all autonomic biological functions.
** There's also the older skill Breath Control, which is classed as Mental/Very Hard and is "not normally taught outside Oriental cultures." It triples the time you can spend underwater, among other benefits.

* ''TabletopGame/{{Paranoia}}'': the mutant abilities of Adrenaline Control (increase Strength and Endurance), Chameleon (skin pigments) and Suspended Animation.
* ''[[TabletopGame/{{Traveller}} Traveller Classic]]''. The psionic ability of Awareness allowed Suspended Animation, the Regeneration of injuries and enhanced Strength and Endurance.
* Pops up a few times in ''TabletopGame/NewWorldOfDarkness'' as a low-level power in physical-based power sets, such as the Life Arcanum in ''TabletopGame/MageTheAwakening'' or the Corporeum Transmutation in ''TabletopGame/PrometheanTheCreated''.
* ''TabletopGame/VampireTheRequiem'': {{Justified|Trope}} since vampires have no bodily functions and can control their own blood. With effort, they can give themselves signs of life like a heart beat, blood flow to the skin, and so on -- enough to be at least superficially convincing. One NPC is quite proud that she's learned to sweat and imitate the smell of menstruation, which she thinks really completes the facade.
* The ''TabletopGame/StarWarsD20'' RPG allows trained Jedi to enter a hibernation trance that drastically reduces their need for air, water and food.
* There is a psychic discipline of Soma in the ''TabletopGame/FadingSuns'' setting, which is described as a PsychicPowers-based extension of yoga and other body control skills. (For that matter, SuperSenses-related powers in this game are a domain of extrasensory perception, which is a separate discipline.)
* ''TabletopGame/EclipsePhase'' has the Endocrine Control biomod that allows one to control their appetite, emotions, and pain. In game effects gaining bonuses against hunger, fear, and emotional manipulation, and also when lying, and they can stay awake for 48 hours straight and ignore the penalties from one wound. Also, the entire list of Psi-Chi [[PsychicPowers Sleights]] is a variety of different special abilities ranging from emotional control to savant calculation to a sanity-restoring AngstComa.

[[folder:Web Comics]]

* ''Webcomic/SchlockMercenary'': Carbosilicate [[BlobMonster Amorphs]] have voluntary control over their own biochemistry. Schlock usually uses it to [[ExtremeOmnivore eat anything]], but he's also used it to neutralize the digestive juices of bigger predators and to fight off NanoMachine infections.

** It also has a Daredevil-inspired vigilante called Warden whose power is essentially "mind-over-everyone's-body" -- including his own.
** Rex Umbrae, genetically-enhanced crimelord, "... ''is capable of halting his bodily processes well enough to be confirmed dead to casual inspection, then return to activity several minutes later''."
* ''Website/SCPFoundation'': SCP-1475 is a man who created a drug that allowed him to use [[NinetyPercentOfYourBrain 100% of his brain]], giving him complete control over his own body to the point where he [[TheSleepless rewired his brain to remove the need for sleep]]. However, in a {{Deconstruction}}, he now has to do manually what his body used to do automatically. Like keep his heart beating and digest food. As a result, [[AndIMustScream he is left permanently bedridden]] because keeping himself alive takes up so much of his concentration that he can't do anything else.

* ''WesternAnimation/AvatarTheLastAirbender'': Avatar Kyoshi's supernaturally extended lifespan comes from one of her teachers (albeit in the novelization ''Rise of Kyoshi'') showing her how to do this.
* In the episode "A Better World" of ''WesternAnimation/JusticeLeague'', the Flash [[PlayingPossum feigns death]] by making his heart beat so fast that it looks like he's flat-lining.
* In the ''WesternAnimation/KingOfTheHill'' episode "Death Picks Cotton", when Cotton is on his deathbed, he takes one last opportunity to {{Troll}} everybody by making it look like he's flat-lining several times. Then he makes himself die for real, just to spite his series-long SitcomArchNemesis Peggy.

'''Cotton:''' ''[smiling]'' Do ya now? Hehehe... ''[dies]''
* Geeker from ''WesternAnimation/ProjectGeeKeR'' has this down to the molecular level, making him a PhysicalGod. Or at least it would if he wasn't a total CloudCuckoolander who has no idea how powerful he really is. This is due to him being freed before the loyalty program (which also contained all of the intelligence) could be installed.
* ''WesternAnimation/TheSimpsons'': Bart once displayed the ability to control his own immune system. When the Osaka Flu hits Springfield, he is completely unaffected, much to his dismay (he wanted to get out of school). So, with some intense concentration, he manages to get his antibodies to stop fighting the virus.

* ''WesternAnimation/StarVsTheForcesOfEvil'': In "Cleaved", Janna reveals she can make her heart stop for about a minute. She uses this to distract some paramedics and allow Marco to leave.

* In one recorded incident involving hypnosis, the subject relived a heart attack. Their heart stopped for 22 seconds (they were hooked up to a EKG). Sometimes the line between fiction and reality is thinner out than we think.

* In one recorded incident involving hypnosis, the subject relived a heart attack. Their heart stopped for 22 seconds (they were hooked up to a EKG). Sometimes the line between fiction and reality is further out than we think.

* Eddie learns in ''ComicBook/Venom2021'' that, after a power upgrade, he has total control over his physical form. This allows him to [[FromASingleCell self-ressurect from his remains]], use UninhibitedMusclePower and ignore the damage that ensues because he can [[HealingFactor immediately patch himself up]], and extend his internal organs such as intestines and nerve endings to grapple with.

* ''Franchise/JoJosBizarreAdventure'':
** The Pillar Men from ''Manga/JojosBizarreAdventureBattleTendency'' take this trope to [[BodyHorror sick]] [[LovecraftianSuperpower extremes]], being able to manipulate their bodies in various ways, from using their rib cages as bear traps to using their blood vessels as tendrils that spit boiling blood.
** In ''Manga/JoJosBizarreAdventureTheJOJOLands'', Paco Laburantes' Stand, The Hustle, gives him advanced control over his muscles, letting him grab things with any part of his body.
* This is the core element behind ''Enbu'', or Monkey Martial Arts, in ''Manga/{{Toriko}}''. It involves unifying literally every single cell in your body for a single purpose. Doing so can enhance your abilities far beyond the norm and allow traversal through otherwise deadly environments.

* The 2008 ''Film/{{The Incredible Hulk|2008}}'' movie has Banner learning to suppress his transformations with ujjayi breathing and meditation. [[spoiler: It was also used later to trigger a controlled transformation]].

* The Pillar Men from ''Manga/JojosBizarreAdventureBattleTendency'' take this trope to [[BodyHorror sick]] [[LovecraftianSuperpower extremes]], being able to manipulate their bodies in various ways, from using their rib cages as bear traps to using their blood vessels as tendrils that spit boiling blood.

* Izuku in ''[[https://www.fanfiction.net/s/13198312/2/Total-Command Total Command]]'' realizes several years late that he has a Quirk in the form of full control over his body. While initially subconscious, such as his throat muscles working to vomit up the Sludge Villain, once Izuku becomes aware of it, he starts consciously producing more hemoglobin and HGH (a growth hormone) while constantly keeping his heartbeat optimized.

* ''Series/TheBionicWoman'' (1970s) episode "Biofeedback", which has a guest character who could use biofeedback to control his own bodily functions.

* Xander Harris in the Journeyverse series (a ''Series/BuffyTheVampireSlayer'' fanfic by Tenhawk) has an increasingly thorough mastery of his body; he is able to pump more blood to his brain to stay conscious under high-gee conditions and heal wounds faster via meditation. He is even able to force a Goa'uld symbiote out of his body by making it an unforgivingly hostile environment (he reversed the flow of carbon dioxide into his blood, pumped out toxic amounts of adrenaline, stopped his kidneys -- all while keeping his brain alive just long enough.)
