Vampiric Draining is a characteristic of certain supernatural creatures. These creatures nourish themselves by draining some vital element from living beings. It may be blood or other bodily fluids, [[EmotionEater mental or emotional energy]], LifeEnergy or [[SoulEating souls]], or [[{{Mana}} magical or spiritual power]].

The effects of being the victim of Vampiric Draining depend on how much vitality the Vampiric Drainer took from you, and range from temporary tiredness to chronic exhaustion, to either shortening of lifespan or RapidAging (thus overlapping with LiquidAssets), to death. The victim may also [[TheVirus transform into the same type of creature that fed upon them]].

Draining LifeEnergy is a bit more common for "vampiric" creatures that are closer to the sci-fi end of the MagicVersusScience spectrum. The trope can also include "vampiric" weapons - that is, {{Evil Weapon}}s that perform Vampiric Draining upon either their wielder or felled enemies/victims.

There are many motivations for draining others. Some of them include:
* Food (classic-style vampires).
* [[ThePowerOfBlood Enhancing their power]].
* Satisfying a [[HemoErotic blood-consumption]] [[BloodLust fetish]], HorrorHunger or other psychological addiction.

SuperTrope to KissOfTheVampire (where the vampiric feeding is either tolerable or pleasurable to the "victim") and VampireBitesSuck (where the feeding is not a nice experience for the victim).

Particular types of draining can be found in LifeDrinker, EmotionEater, and SoulEating.

Often overlaps with HorrorHunger. May involve BloodLust if that's the substance that's drained. See also OurVampiresAreDifferent, and SupernaturallyDeliciousAndNutritious.

Not to be confused with LifeDrain and ManaDrain, which are stealing HitPoints and ManaPoints from an opponent for yourself respectively.

LivingBattery is the ScienceFiction equivalent of this trope.



[[folder: Anime & Manga]]
* ''Manga/{{Bleach}}''
** Hollows feed on spiritual energy as a secondary source of nourishment (the primary being the "hearts" of both living and dead Humans). Sources include humans, Soul Reapers and other hollows.
** Another example would be [[AlmightyJanitor Ayasegawa Yumichika]]. This [[MoreThanMeetsTheEye ordinary]] {{Bishonen}} BloodKnight is [[ObfuscatingStupidity hiding]] his [[CoverBlowingSuperpower true power]], which [[EnergyAbsorption drains the spiritual energy]] of his target. When he does [[LetsGetDangerous decide]] to use it, his battles end with a [[CurbStompBattle single strike]]. He can then use the drained energy to heal his wounds.
* Evangeline A.K. [=McDowell=] from ''Manga/MahouSenseiNegima'' has the standard "vampire sucking blood" variant. She doesn't actually need blood to survive, but drinking it causes her to gain strength.
* Several ''Youkai'' in ''Manga/InuYasha'', as is, occasionally, the title character's sword.
* Okoi from ''Manga/{{Basilisk}}'' can suck the blood of her enemies by touching their skin with hers. She vomits the blood out afterwards though, so it's basically just a way to attack and nothing more.
* ''Manga/JojosBizarreAdventure'' has vampires in the first three parts, each of which feed on blood... with their ''fingers''. They need it to heal their wounds (and in Dio Brando's case, [[spoiler:to finalize the connection of his head to Jonathan Joestar's body]]). Part 4 gives us the Stand Highway Star, which breaks down a person's body by draining the nutrients from their cells; its user uses the stolen nutrients to help him recover from grievous wounds suffered in a motorcycle accident.
* The [[spoiler:true form of the Juubi]] in ''Franchise/{{Naruto}}'' is capable of draining all of a shinobi's chakra in seconds. This is invariably fatal.
* ''Anime/WickedCity''. The Black World radical masquerading as a call girl absorbs [[spoiler:Giuseppe]] into herself and drains almost all of his LifeEnergy.
* ''Literature/DemonCityShinjuku''. In the 1988 OVA Chibi tells Sayaka Rama that the Fire Demons take the form of young children and roam the city sucking the life force out of any human or animal that crosses their path.
* ''LightNovel/VampireHunterD''. In the 1985 film the three Snake Women of Midwich drain D's LifeEnergy by wrapping themselves around him.
* In ''Anime/DigimonAdventure'', to make up for his weakened strength in the real world, Vamdemon[=/=]Myostismon attacked women at night, draining them of blood and leaving them with anemia.
* In ''Manga/DeathNote'' when a {{Shinigami}} kills a human with a [[RealityWritingBook Death Note]] their remaining lifespan is added to the shinigami's. They can also take half the remaining lifespan of a human who owns a death note in exchange for the power to see people's true names by looking at their face.

[[folder: Comic Books]]
* In the MarvelUniverse, Selene is a "psychic vampire" who can drain the LifeEnergy of human beings into herself. If she drains the victim's entire life force their bodies crumble into dust. She must drain life force on a regular basis to renew her vitality and youthful appearance. She can use absorbed life force to enhance her physical strength, speed, stamina, agility, reflexes, and durability to superhuman levels.
* Non-villainous example: ComicBook/{{Rogue}} of the ''ComicBook/XMen'' has this due to her mutation, enabling her to drain LifeEnergy and temporarily borrow someone else's powers. Because of PowerIncontinence, she can't touch anyone without draining their strength, which is [[BlessedWithSuck understandably harsh on her social life]].

[[folder: Fan Works]]
* The wraiths on the Plains of Death in ''Fanfic/WithStringsAttached'' feed off Paul's life energy—except he has so much that they explode from overeating.
* Doraku from ''FanFic/AGrowingAffection}'' is a rather AffablyEvil and polite man who outright explains to a captive Naruto, Sakura, Hinata and Lee that he falls under "enhance his power" from drinking blood (he insists that his demon clan aren't vampires but did inspire them) saying he gains whatever ability the person has. He never drinks someone to death though just tastes the blood and it works. Has the side effect of enslaving people he drinks.
* ''Fanfic/BesidesTheWillOfEvil'': [[BigBad Reiziger]] has the ability to literally suck the life out of living creatures to heal and strengthen himself, leaving his victims as grey, aged and desiccated husks. He keeps growing consistently stronger and more powerful as the story progresses, consuming more and more lives to add to his power.

[[folder: Film]]
* ''Film/{{Lifeforce}}''. The three space vampires drain LifeEnergy from humans to sustain themselves (and to store in their ship for future use during their long hibernations). The humans they drain become zombies who must drain LifeEnergy from other humans every two hours or be turned to dust.
* In ''Film/ScannerCopII'', psychic 'scanner' Carl Volkin devours the lifeforce of other scanners to add to his own power. Staziak even compares him to a vampire at one point.
* In the ''Film/XMenFilmSeries'', Rogue can do this through touch.
* In ''Film/HocusPocus'', the three witches do this to a young girl to maintain their youth.
* In ''Film/GodzillaFinalWars'', Kaiser Ghidorah could drain Godzilla's power with his bite.

[[folder: Folklore & Mythology]]
* [[HornyDevils Succubi]], in some presentations, drain the life-force of their victims through sexual contact. White Court vampires in ''Literature/TheDresdenFiles'' are one example. [[TheInternetIsForPorn In some cases]], the life-force is carried in the victim's semen, which the succubus has to, um, ingest.

[[folder: Literature]]
* Naturally a staple of Vampire Fiction, from ''Literature/{{Dracula}}'' to ''[[Literature/TheVampireChronicles Interview With the Vampire]]'' to ''Literature/{{Twilight}}'' and more.
* The Others in the ''Literature/NightWatch'' can collect the emotional energy of the {{Muggles}} and convert it into mana. In a twist, the [[LightIsNotGood nominally-good Light]] Others can only "feed" on positive emotions, whereas the [[DarkIsNotEvil "bad" Dark]] Others take away painful and unpleasant feelings.
** Should be noted though that in order to have emotions to feed upon, the Light Others foster positive emotions in their environment, whereas Dark Others foster negative emotions.
** This is expanded in later novels, when Anton finally figures out that the Others are parasites, and magic proficiency is determined by a person's own ratio of magic production vs. absorption. Humans produce more magic than they absorb, while the Others absorb more than they produce, allowing them to use it. The higher the absorption/production ratio, the more powerful the Other. Zero-level Others only absorb and can do anything they want with ease. This also means that being far away from humans (say, in orbit or on another planet) would render an Other powerless.
*** In one book, a disillusioned Other wishes to turn every human into an Other using an ancient magical text. While the obvious problem with this is mentioned (i.e., absolute chaos), it is not mentioned that it would also drastically reduce the supply of magic in the world, making it almost impossible to cast spells.
* In the novels of ''Literature/{{Deverry}}'', several of Rhodry's prior incarnations are unintentionally killed by their lover, a former air elemental who was transformed into something akin to a succubus by a Guardian. She used the drained energy to gradually make her manifestation form more human.
* Vardalek in Eric, Count Stenbock's ''True Story of a Vampire'' appears to be what we'd recognize as a psychic vampire, gradually draining the life from his prepubescent thrall.
* The weaponized variant of Vampiric Draining shows up in the Kull the Conqueror story "Riders Beyond the Sunrise," where Kull confronts his ArchEnemy, [[DoomyDoomsOfDoom Thulsa Doom]]. The sorcerer wields a sword that slowly saps Kull's strength and transfers it to Doom, allowing him to fight without tiring while Kull gets weaker and weaker. Disarming Doom and swapping his normal sword for the magical blade allows Kull to defeat the sorcerer.
* The dementors from the ''Literature/HarryPotter'' series.
* Elves in Creator/MCAHogarth's ''Literature/TheBloodLadders Trilogy'' keep human slaves in order to drain magic from them, as their immortality uses up more of their own magic as they age.
* ''Literature/WayOfChoices'' Bai Hai, an otherwise normal human, captures Xu Yourong the Phoenix, to drain her unusual blood and steal her power. He manages only because she was already wounded, poisoned and weak almost unto to death, and swiftly [[LaserGuidedKarma dies from the poison in her blood.]]

[[folder:Live-Action TV]]
* The Fangire, and indeed most of the Demon Races seen in ''Series/KamenRiderKiva''.
* The Wraith from ''Series/StargateAtlantis'' feed on the life force of humans. Being fed upon by a wraith shortens the victim's lifespan, and produces RapidAging. It provides the Wraith with both bodily nourishment, and fuel for their HealingFactor. Notably, Wraith can also work this ability ''backwards'', de-aging someone. They usually use both to "train" captive humans, eventually getting them addicted to the Wraith. This is how they control Wraith-worshipers, whenever it's necessary to use humans (e.g., infiltration).
* A classic episode of ''Series/TheTwilightZone'' entitled "Queen of the Nile". A middle-aged actress named Pamela Morris is actually an ancient Egyptian queen who is thousands of years old; she maintains her youth by draining the LifeEnergy of young men with a magic scarab beetle. [[spoiler:And she succeeds in draining our protagonist Jordan Herrick to death.]]
* The final season of ''Series/EarthFinalConflict'' introduces the Atavus, the original race that split into Taelons and Jaridians. Being away from their homeworld, they have to replenish their energy on a daily basis by feeding on sentient beings (in this case, humans) using their energy claws. The subject doesn't survive the process. The Atavus found that they really enjoy the feeding process. Their chambers allow them to create human/Atavus hybrids who also have this ability.
* In ''Series/{{Supernatural}}'', [[Characters/SupernaturalDjinn the djinn]] drain blood or fear from their victims.
* ''{{Series/Beyond}}'': The beings in the Realm appear to feed this way, as Frost ages rapidly when touched by one.

* ''Series/StarTrekTheNextGeneration''
** In the episode "Man of the People" the Enterprise transports an ambassador, Alkar, who forms a connection to women and does this in reverse, offloading his negative emotions on them, allowing him to be clear-headed in negotiations, but causing RapidAging and death to his victims.
** "Time's Arrow'' has the Devidians, invisible aliens who steal human neural energy to live (one wonders [[FridgeLogic how they survived to evolve to sapience]]) and who go back in time to prey on humanity in the 19th Century, when there were still plagues to excuse mysterious deaths.
** "Sub Rosa" reveals a ghost-like energy being has done this to many generations of Beverly Crusher's family.

[[folder: Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons''
** The Cerebral Parasite and Brain Mole feed on psionic energy, which can kill their victim.
** The WillOWisp haunts places like bogs, swamps and dungeons where death traps like mires, quicksand and {{Pit Trap}}s can be found. It tries to lure adventurers into those traps so it can feed on their fleeing LifeEnergy as they're dying.
** Not to mention actual [[OurVampiresAreDifferent vampires]], who feed on both blood (Constitution points) and life force (negative levels), and Wights (weaker undead who drain life through slam attacks).
** The 3rd Edition spell Death Knell drains the LifeEnergy from a dying creature, killing it. Doing so increases your strength, your {{Hit Point}}s and adds 1 to your CharacterLevel for the purposes of spellcasting.
** There's also the classic 3rd level wizard/sorcerer spell Vampiric Touch which drains health points from the victim to replenish lost health.
** Original D&D Supplement IV ''Gods, Demi-Gods & Heroes''
*** In the Melnibonean mythos, the rune sword Stormbringer [[YourSoulIsMine feeds on souls]] and LifeEnergy. The monster Quaolnargn consumes LifeEnergy. Vampire trees can send their leaves through the air to suck the blood out of their victims.
*** In the Hyborian mythos based on Creator/RobertEHoward's ''Literature/ConanTheBarbarian'' stories, the Kraken feeds on human [[YourSoulIsMine souls]] and LifeEnergy from its victims.

** ''Magazine/{{Dragon}}'' magazine #238 article "The Return of the Wizards Three". The spell Scourge of Stars creates a magical whip that drains HitPoints from creatures it hits and bestows them on the caster. If the caster is injured the extra HitPoints heal those injuries first. If any are left over they heal any future injuries for the duration of the spell.

* The Vampiric Bite and more generic Leech powers from ''TabletopGame/{{GURPS}}''.
* All Elohim in ''TabletopGame/DemonTheFallen'' require Divine Faith to live and cast magic, and the only way the Fallen can obtain it is from humans, the image of {{God}}. For this, they can either reveal themselves to certain humans and let their Faith trickle to them constantly, or reap them for all their Faith in a one-time boost. Unlike vampires, demons don't actually expend Faith by merely existing.
* ''Space Gamer Fantasy Gamer'' magazine #7, article "Villains Finish First!". The super villain Vampire Prince of Darkness can use his power Drain [[LifeEnergy Life Force]] on an opponent to weaken their soul.
* Mongoose Publishing's ''Strontium Dog'' RPG. The alien criminal Xen the Brainwraith enters a victim's skull, settles around the brain and exerts MindControl over the victim. Each day it remains in the victim's head it drains a point from one of the victim's four physical characteristics (Intelligence, Strength, Endurance and Dexterity, in that order). When the victim's Intelligence is reduced to zero the victim becomes a zombie. When all four reach zero the victim dies. It has killed hundreds, if not thousands of people.
* This is one possible (though far from the only) use for the generic "Drain" power in the ''TabletopGame/HeroSystem'', which depending on precisely how it is defined can temporarily lower ''any'' characteristic or power and isn't hard to link with an appropriate Aid effect to the character's (or monster's) own. At least one earlier edition provided both effects in one convenient package via the separate Transfer power, but Sixth Edition no longer includes this; the Drain/Aid combination can model pretty much any desired effect along the lines of this trope with more flexibility, anyway.
* The Dark Eldar in ''TabletopGame/{{Warhammer 40000}}'' work like this, due to the curse Slaanesh the god(dess) of pleasure put on them. Dark Eldar feed on soul energy, and one of the most effective ways to gain it is torture their victims in absolutely horrifying and unimaginable ways. They need to do this to keep themselves young, otherwise they'll rapidly age and die, and then fall into the clutches of Slaanesh who's in hell waiting for them.

[[folder: Video Games]]
* VideoGame/{{Metroid}}s, from the series of the same name, feed on life energy and leave their victims as dessicated husks.
** At least one specimen is able to [[InvertedTrope inject energy into others]], too.
* {{Franchise/Nasuverse}}:
** The True Ancestors, who go insane if they completely abstain for too long, but don't actually ''require'' it for sustaining their themselves; the addiction is a purely psychological.
** The Dead Apostles, however, require blood for physical sustenance, making them closer to the classical vampires in this regard.
** Rider from ''VisualNovel/FateStayNight'', who is decidedly '''not''' a vampire, but rather [[spoiler:a Gorgon (namely, Medusa)]].
* ''VideoGame/WorldOfWarcraft'''s Blood Elves, who used to be able to suck the magic out of anything to sate their addiction to mana and keep from degenerating into "lost ones", they no longer possess this ability since their sunwell was restored.

* Venom needs to absorb his victim's energies in ''VideoGame/UltimateSpiderMan''.

* In ''VideoGame/BrainDead13'', Vivi will do this to Lance if he doesn't make a choice of either a shave, manicure, or facial quick enough. And the result is downright unpleasant: though over in a split-second, we see Lance visibly shrivelled into a mummy-like state as a result of her appetite.
** Also, the ghosts with [[JacobMarleyApparel nooses around their necks]] will possess Lance and drain the living soul out of him!
* ''VideoGame/DungeonCrawl'' has the Vampiric Draining spell, which is more of a life-force drain. It's one of the few renewable ways that [[BlessedWithSuck Deep Dwarves]] can heal.
* This is the fundamental play style of Alarak in ''VideoGame/StarCraftII''. He actively heals himself by either killing his own units, or enemy units, and won't survive long without doing so.
* ''Franchise/TheElderScrolls''
** This is obviously a trait the series' [[OurVampiresAreDifferent vampires]]. However, there are over 100 known "bloodlines" of vampire in Tamriel, and each has some distinguishing features and abilities. The majority use the standard BreakingAndBloodsucking method, but others are known to magically drain the health of their victims or swallow their victims whole instead.
** This is an ability of the Hunger, a form of [[OurDemonsAreDifferent lesser Daedra]] very similar in appearance to the "alien-style" {{Chupacabra}}, complete with claws, spikes, and a "sucker" mouth. Hungers are capable of draining the Fatigue of their prey. In game, this tends to take the form of a spell, but given their appearance (and the fact that the "spell" is immune to Silence), it can be implied that they are really using their sucker-like mouths.
** In ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'''s ''Dragonborn'' DLC, this is an ability of the Seekers, a {{Cthulhumanoid}} form of lesser Daedra in service to Hermaeus Mora, the [[OurGodsAreDifferent Daedric Prince]] of [[KeeperOfForbiddenKnowledge Knowledge]]. All of their spells drain or absorb the health, magicka, and/or fatigue of their targets. Additionally, these spells are ranged and [[HomingProjectile home-in on their targets]].

* This has appeared ''a lot'' in ''Webcomic/OrderOfTheStick'' since the story first introduced vampires and [[spoiler: Durkon became one, and the High Priest of Hel, leading a group of vampires in a quest to destroy the world.]]
* In ''Webcomic/{{Untouchable}}'', modern vampires have learned to discreetly feed off humans' energy by touching them. It's relatively harmless but can cause temporary lassitude.
* In ''Webcomic/CharbyTheVampirate'' An-Keth can pull life energy from anything around them including plants to speed up their already impressive regeneration abilities when badly injured, leaving a patch of dead plants and other remains wherever they were when doing so.

* In the ''Literature/WhateleyUniverse'', this is one of Vamp's powers. If she draws too much energy from the victim (say, a mutant with Energizer powers) she tends to go bananas until it wears off.
* ''Wiki/SCPFoundation'':
** [[http://www.scp-wiki.net/scp-472 SCP-472 ("The Bloodstone")]]. Anyone who goes within 18 meters of SCP-472 will lose up to 1.35 percent of their biomass. It's implied in the article that it's somehow feeding on its victims by draining their blood.
** [[http://www.scp-wiki.net/scp-522 SCP-522 ("Blood-draining Carpet")]]. When a human being stands on the middle of the carpet, it will wrap itself around the person, insert thousands of hairs into the them and drain them of all of their blood in a few minutes.
** [[http://www.scp-wiki.net/scp-742 SCP-742 ("Retrovirus")]]. People infected with SCP-742 will drain the bone marrow from other humans. The stem cells in the marrow allow them to cease aging, and stem cells taken from fetuses allow them to create a SCP-742 filled fluid that they can infect into other humans in order to infect them.
** [[http://scp-wiki.net/scp-932 SCP-932 ("Night Feeder")]]. If the creatures are not fed they will attack people who are awake. This will so severely drain the victim that they will be rendered comatose and eventually die of a heart attack. The draining process has the side effect of allowing the creatures to reproduce.
** [[http://www.scp-wiki.net/scp-1421 SCP-1421 ("The Unreliable Oracle")]]. SCP-1421 drains the LifeEnergy of all living beings within five meters of it. This has an effect similar to long term fasting, eventually causing death and mummification of the corpse.
** [[http://www.scp-wiki.net/scp-1448 SCP-1448 ("LegendTripping")]]. SCP-1448 encourages people to perform rituals that shed blood where it lives. No trace of the blood can be found afterward, because SCP-1448 absorbs it.
** [[http://www.scp-wiki.net/scp-1529 SCP-1529 ("King of the Mountain")]]. After SCP-1529 uses its HypnoticEyes to take control of a victim, it approaches them and drains their heat energy, causing them to die of hypothermia.
** [[http://www.scp-wiki.net/scp-1627 SCP-1627 ("Mushroom Wars")]]. When a human being touches a SCP-1627-A, over the next two weeks the human will undergo RapidAging until death. This provides sustenance to the SCP-1627-A.
** [[http://www.scp-wiki.net/scp-2056 SCP-2056 ("Tsiatko")]]. SCP-2056 has a funnel-shaped mouth lined with sharp teeth. It bites large trees with its mouth in order to drain nutrition. This leaves the tree dessicated, malnourished and 73% likely to die.

* ''WesternAnimation/JonnyQuest'' TOS episode "The Invisible Monster". The title creature can drain the [[LifeEnergy energy from a human body]] by touch, thus "consuming" the person.
* Given their fangs and WordOfGod claiming they were based on succubi, it's ''very'' heavily implied the Changelings feed this way on ''WesternAnimation/MyLittlePonyFriendshipIsMagic''. The show's time slot won't allow for any more details than "they feed on love", however.
** If you consider the IDW comics to be canon, then this is ''very much confirmed'' with a side order of NightmareFuel. [[http://i29.photobucket.com/albums/c282/Hyaroo/MLPFIM_3_TheGroup_006_zps5b02e8c1.jpg?t=1360615219 Take a gawk.]]
* A Halloween episode of ''WesternAnimation/TheSimpsons'' has Homer being attacked by a pair of vampires that suck out his blood, only for the two of them to grow fat and pass out due to also absorbing Homer's unhealthy high cholesterol and fat. Homer still turns into a bat after the fact.
* Rather than draining people of their blood like in most other versions, in ''WesternAnimation/{{Ultimate Spider-Man}}'' Michael ComicBook/{{Morbius}} drains people of their LifeEnergy.

* [[CaptainObvious Vampire bats]].
* Ticks, lice, fleas, mosquitoes, and leeches all drink blood, but are so small that they don't individually do significant harm (unless they transmit a disease).
** Also, bedbugs. They aren't vectors for any diseases, so at least they won't cause a disease outbreak. But infestations tend to be persistent. They're astoundingly hardy, seem to actively prefer humans, can go for months without needing to eat, [[ArsonMurderAndJaywalking and can leave thousands of annoying, scratchy bites all over you]]. There is a reason why most landlords tend to put some sort of clause in the new lease stating that you'll be held financially accountable for an infestation if it can be traced back to bugs that came with you.
* Male garter snakes, newly arisen from winter hibernation, will sometimes mooch off other male snakes' body heat so their ectothermic bodies can warm up and become more active. By acting and emitting an aroma like a ''female'' garter snake, the chilly male attracts snakes that have already basked in the sun to cluster and coil around him, transferring their accumulated warmth to the supposed female they're trying to court.
