A PureMagicBeing is [[MadeOfMagic magic incarnate]]. Such beings have extraordinarily strong magical powers, sometimes approaching godlike levels. For Pure Magic Beings, magical energy is frequently indistinguishable from LifeEnergy, so that running out of magic power means death, or fading out of existence. Things that consume or drain magic can be very dangerous to Pure Magic Beings.

Although reminiscent of EnergyBeings, Pure Magic Beings usually have physical forms, though those forms are sometimes rather mutable.

[[folder:Anime and Manga]]
* Yue from ''Manga/CardcaptorSakura'' As a being created from the moon (And the moon being able to only reflect power) he is in danger of ceasing to exist because Sakura is too young to generate enough magic to support his existence.
* In some way, this could be said of [[spoiler:the majority of the MagicWorld's denizens]] in ''MahouSenseiNegima''.
* The Wolkenritter of ''MagicalGirlLyricalNanoha''. Made especially apparent near the end of ''A's'', [[spoiler:where draining them of their {{mana}} caused them to [[DisappearsIntoLight disappear into light]]]].
** This also becomes a ''major'' weakness in Force where they are vulnerable to the Eclipse infectees and their dividers. [[spoiler: Signum is in the hospital for ''months'' thanks to Cypha tearing her to shreds]].
* The mazoku in ''{{Slayers}}'' are primarily astral beings, so their physical manifestation is only a projection amounting to a fraction of their true power. Also, since the astral domain is ruled by PsychoactivePowers (being the domain of the mind/soul) this gives them the ability to be directly bolstered or harmed by emotions, and the WeaksauceWeakness that the harm to their ego caused by fully acknowledging more powerful beings could literally cause one to disappear in a PuffOfLogic.

[[folder:Comic Books]]
* Dormammu from ''Comicbook/DoctorStrange'', of an entire race of such beings called Faltine. He and his sister are [[MySpeciesDothProtestTooMuch considered abominations]] for they crave matter rather than energy.

[[folder:Literature]]
* In ''The Second {{Chronicles of Thomas Covenant}}'':
** The Elohim people are Earthpower incarnate.
** Covenant himself is transfigured into a being of pure Wild Magic at the end of ''White Gold Wielder''.
* Simkin from ''Literature/TheDarkswordTrilogy''
* The fairies from ''Literature/TheLastRune'' series by Mark Anthony. When they travel to Earth, where magical power isn't nearly as common as on Eldh, they suffer horrific pain and slowly die unless they take special drugs.
* The gods in Trudi Canavan's ''Literature/TheAgeOfTheFive''.
* Many of Creator/HPLovecraft's {{Eldritch Abomination}}s, including Cthulhu, Azathoth, and certain avatars of Nyarlathotep.
* ''Literature/TheDresdenFiles'':
** Most of the non-humans that Harry Dresden encounters are Fae, beings made of Ectoplasm and magic. Because magic is so intrinsic to their nature, they have perfect control over their use of it, unlike wizards. Wizards have spillage, and so they can't use modern technology because they short it out. [[WordOfGod The world]] simply doesn't like Harry Dresden.
** It's unclear if Angels and Demons (which do exist) are made of Soulfire and Hellfire, respectively, or just use it as a power. Because both of those magics are fueled from one's soul, they would be perfect examples of this trope.
* Spren in ''Literature/TheStormlightArchive''. Though very powerful in their own Realm, they are mindless in the Physical Realm unless they find a human to bond to. Such a bond lets the spren use the human's brain and the human use the spren's powers.

[[folder:Video Games]]
* Espers and the Ultima Weapon in ''FinalFantasyVI''. You can actually kill Ultima Weapon by draining its MP to zero.
** Several normal enemies (generally with a consistent techno-organic design scheme) also follow this, down to dying if their magic points are zeroed out.
* The BigBad of ''NeverwinterNights2'', the King of Shadows is a creature of pure shadow weave magic.
* BigBad Pain Elemental [[EldritchAbomination Chzo]] of the ''VideoGame/ChzoMythos''. [[spoiler: He'd actually die of magical starvation if he ever crossed over to our dimension since there isn't enough magic to sustain him.]]
* The [[PhysicalGod "Aggregate Sentiences"]] in ''VideoGame/TalesOfTheAbyss'' are this, and since the same spirits show up as [[SummonMagic summons]] in most installments of the Tales Series, it's theorized that this is the case for other instances of the spirits as well.
* Ghosts and other strange things in ''AtelierSeries'' games effectively have 0 HP, but they will, uh, die when they have 0 MP. It's possible for a ghost character --such as the recurring character Pamela-- to, well, kill themselves by casting spells that require more MP than they have.
* Xerath is ''VideoGame/LeagueOfLegends'' performed a ritual to turn himself into one of these, as a human body was limiting his power.
* The Fae in ''VideoGame/KingdomsOfAmalurReckoning'' are described as beings of pure magic. This actually works against them -- the [[GreenRocks Prismere]] that empowers the Tuatha warps their minds due to the Prismere screwing with the magic within them, which is why all of them are such brutal destructive warmongers. Mortals on the other hand can wield Prismere with no ill effects.

[[folder: Webcomics]]
* The nether demons of ''{{Drowtales}}'' exist in alternate universes, that any summoner with proper training can open a gate into and unleash them onto the world. These demons have no physical form and typically are unintelligent, spending all their time in the physical world feeding off of mana and auras of the plants and animals around them. They are feared and hated by most Drow, as demons also having the nasty habit of invading the bodies of aura bearing creatures, either simply tainting them, or taking over their entire body and killing the host, well twisting it into a mindless creature that attacks anything nearby.
** [[spoiler: It is revealed later in the series that the ''audience and readers'' of ''{{Drowtales}}'' are in fact also demons, which can only be seen by Kiel.]]

[[folder:Western Animation]]
* The enchantress Mara, from the 1981 cartoon series ''{{Blackstar}}''.
* One episode of Disney's ''Disney/{{Aladdin}}'' TV series featured Genie being hunted by a magic-eating creature.
* On ''WesternAnimation/{{Gargoyles}},'' [[TheHero Goliath]] describes [[TheFairFolk the Third Race]] as "beings of pure magic." Their ruler, [[ChaoticNeutral Oberon]], is basically a PhysicalGod, and even [[GreatGazoo Puck]] manages to shapeshift an entire city twice in one night.
* [[WesternAnimation/Ben10AlienForce Anodites]] are [[MadeOfMagic Made of]] [[TheForce Mana]], essentially making them lesser {{Reality Warper}}s without casting any real spells. In [[ShoutOut very much the same vein]] as the aforementioned (but obscure) Faltine of Marvel comics.
* The Father, the Son and the Daughter in ''WesternAnimation/StarWarsTheCloneWars.''
