* In one episode of ''Series/TheIncredibleHulk'' (1970s TV show), 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 one episode of the ''WesternAnimation/JusticeLeague'', the Flash feigns death by making his heart beat so fast that it looks like he's flat-lining.

But this girl can.

* 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.

Supernatural versions can enable BloodyMurder and BadWithTheBone.

* 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.

** After the TimeSkip, Chopper no longer needs the Rumble Ball for six out of his seven forms, when previously he needed it for any transforming beyond the three-form Zoan standard.

But this guy can.

It can be due to [[CharlesAtlasSuperpower extensive training]], to BioAugmentation, {{Nanomachines}} or just be a [[StockSuperpowers Superpower]]. As explained in [[http://en.wikipedia.org/wiki/Biofeedback the other wiki]] and in RealLife below, this can also be TruthInTelevision.

* 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.

* ''Film/{{Lucy}}: the protagonist gains this as part of her first power-up.

** Sage of the Comicbook/{{X-Men}} has conscious control over her body functions thanks to her "computer brain" mutant ability.

It can be due to [[CharlesAtlasSuperpower extensive training]], to BioAugmentation, {{Nanomachines}} or just be a [[StockSuperpowers Superpower]]. As explained in [[http://en.wikipedia.org/wiki/Biofeedback the other wiki]] and in RealLife below, this can also be TruthInTelevision. Stronger fictional wielders of this ability can exhibit abilities such as FeelNoPain, SuperSenses, SuperStrength, HealingFactor, VoluntaryShapeshifting and/or even {{Immortality}}. [[LogicalExtreme At the greatest extremes]], they may even be able to alter specific molecules in their bodies or meddle with their own cellular pathways. More often though, their capabilities ''merely'' extend to conscious control of normally autonomic and subconscious physiological processes.

Often {{Hand Wave}}d by NinetyPercentOfYourBrain and other cases of ArtMajorBiology. [[JustForFun/IThoughtItMeant The title is decidedly not a]] ''Series/{{Seinfeld}}'' reference.

Subtrope of {{Biomanipulation}}; here, the manipulation is to one's own body. BloodyMurder and BadWithTheBone may stem from this, as well.

This trope should not be mistaken for DomainHolder which is the trope of someone being the owner and thus controller of the physics of a location, often an extradimensional space.

* ComicBook/{{Apocalypse}}, the ''ComicBook/XMen'' villain, has this down to the molecular level.

* The protagonist of Ayize Jama-Barrett's ''The Liminal People'' is extremely gifted in {{Biomancy}} and can heal, harm or overhaul the bodies of others almost as easily as he does his own.

** Ninjak: "I could feel my nerve endings like I could feel my fingertips. I could control it all... heal it all."

* Underplayed drastically on ''Series/{{Seinfeld}}'', where "Master of your Domain" simply meant the ability to resist the urge to masturbate. None of them can hold out long. [[AllWomenAreLustful Not even Elaine]].
