4Vampiric 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]].
5
6The 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]].
7
8Draining 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.
9
10There are many motivations for draining others. Some of them include:
11* Food (classic-style vampires).
12* [[ThePowerOfBlood Enhancing their power]].
13* Satisfying a [[HemoErotic blood-consumption]] [[BloodLust fetish]], HorrorHunger or other psychological addiction.
14
15SuperTrope 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). Subtrope of FantasticDietRequirement.
16
17Particular types of draining can be found in LifeDrinker, EmotionEater, and SoulEating.
18
19Often overlaps with HorrorHunger. May involve BloodLust if that's the substance that's drained. See also OurVampiresAreDifferent, and SupernaturallyDeliciousAndNutritious.
20
21Not to be confused with LifeDrain and ManaDrain, which are stealing HitPoints and ManaPoints from an opponent for yourself respectively.
22
23LivingBattery is the ScienceFiction equivalent of this trope.
24
25Not to be confused with CannibalismSuperpower.

27!!Examples:

30
31[[folder:Anime & Manga]]
32* ''Manga/{{Bleach}}'':
33** 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.
34** Another example would be [[AlmightyJanitor Ayasegawa Yumichika]]. This [[MoreThanMeetsTheEye ordinary]] {{Bishonen}} BloodKnight is [[WillfullyWeak 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.
35* ''Anime/KabaneriOfTheIronFortress''. Kabaneri (humans who've undergone partial transformation into the zombie-like kabane) feed on human blood to survive. Without it, they get closer to kabane and try to feed off any nearby human, no longer recognizing their allies.
36* ''Manga/NegimaMagisterNegiMagi'': Evangeline A.K. [=McDowell=] has the standard "vampire sucking blood" variant. She doesn't actually need blood to survive, but drinking it causes her to gain strength.
37* ''Manga/{{Basilisk}}'': Okoi 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.
38* ''Manga/{{Inuyasha}}'': A clan of bat {{youkai}} favor the blood of humans as nourishment, but they can also consume animal blood and possible other alternatives as one, Tsukuyomaru, does not attack humans and has also forbidden his clan to do so.
39* ''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]]). [[Manga/JoJosBizarreAdventureDiamondIsUnbreakable 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. [[Manga/JoJosBizarreAdventureGoldenWind Part 5]] gives us [[spoiler:the BigBad Diavolo, who, while not a vampire, drains ''a young kid's blood'' after surviving a brutal battle with the leader of his assassination team]].
40* 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.
41* ''Anime/WickedCity'': The Black World radical masquerading as a call girl absorbs [[spoiler:Giuseppe]] into herself and drains almost all of his LifeEnergy.
42* ''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.
43* ''Literature/VampireHunterD''. In the 1985 film the three Snake Women of Midwich drain D's LifeEnergy by wrapping themselves around him.
44* ''Franchise/{{Digimon}}'':
45** In ''Anime/DigimonAdventure'', to make up for his weakened strength in the real world [[BigBad Myostismon]] attacked women at night, draining them of blood and leaving them with anemia. The dub removed this explanation, making it seem like Myotismon was attacking the women [[ForTheEvulz for the fun of it]]. However, this wouldn't necessarily be out-of-character for Myotismon...
46** In ''Anime/DigimonGhostGame'', StarterVillain Clockmon preyed on humans by draining them of their "time", [[RapidAging aging them rapidly]] and leaving them near death.
47* 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.
48* ''Manga/AyakashiTriangle'': [[TheHeartless Ikon]] and the creatures [[MetamorphosisMonster born from them]] feed on [[LifeEnergy haku]] taken from humans and other [[OurSpiritsAreDifferent ayakashi]], both to satisfy their HorrorHunger and advance themselves along the BishonenLine. The stronger they are, the faster they can drain: It took hours of an ikon possessing Lu for it to tire her out. A [[HumanoidAbomination jinyo]] like Sosuke gobbles up haku fast enough to use as an attack, paralyzing whatever body part its taken from. Ayakashi are [[EnergyBeings made of haku]], though, so they aren't so much "drained" by ikon as EatenAlive.
49* Subverted in ''Manga/RanmaOneHalf''. Mousse aided a jizo stone statue, which tried to return the favor by taking the appearance of his crush Shampoo and going on dates with him. Since he's tired every time the main characters see him, they think the jizo was sucking out his life, but Cologne figures out at the end that it wasn't intentionally harming Mousse. Mousse was simply exhausted from going on dates all night (with a stone statue in the back seat, no less) on top of his job as a restaurant delivery boy.

51
52[[folder:Comic Books]]
53* ''Franchise/TheDCU'':
54** ''ComicBook/FirestormDCComics'': Killer Frost, unusually for AnIcePerson, can absorb heat in order to strengthen her own powers. She can also do this to ''people'', siphoning their own warmth and freezing them to death. In fact, in the case of the third incarnation, Caitlin Snow, she ''has'' to do this in order to keep herself alive.
55** ''ComicBook/Robin1993'': The villain Johnny Warren gains a whole slew of abilities powered by draining the LifeEnergy out of people after making a demonic pact.
56** ''ComicBook/{{Superman}}'': The villain Parasite has the ability to drain the knowledge, life-force and superpowers of anyone he touches.
57** ''ComicBook/WonderWoman1987'': The Erinyes string up ComicBook/WonderGirl and Ferdiand to exsanguinate them and drink their blood, from which they pull memories and things about their victims.
58* ComicBook/TheHeap is forced to drain animals of blood in order to get oxygen. He targets birds, dogs and livestock, but he usually does not attack men, unless they are evil.
59* ''Franchise/MarvelUniverse'':
60** ''ComicBook/CloakAndDaggerMarvelComics'': Cloak's weaponized TeleportationSickness stems from the fact that anyone enveloped in his "dark dimension" is vampirically drained of LifeEnergy, which Cloak refers to as "the light of the soul". This causes physical depletion and intense psychological distress. Worse, Cloak is at least psychologically dependent on regularly consuming LifeEnergy in this way; if he goes too long without it, [[HorrorHunger withdrawal-like symptoms intensify until he is compelled to feed]]. His partner Dagger is actually a kind of inversion of this trope; she produces ''too much'' LifeEnergy, to the point that if it isn't siphoned regularly, she begins to lose her mind. Thus their partnership is a symbiotic relationship; Cloak keeps his HorrorHunger in check by draining Dagger, which in turn preserves Dagger's mind.
61** ''ComicBook/XFactor2006'': [[ComicBook/DoctorStrange Baron Mordo]] kidnaps Monet St. Croix's father in order to lure her into a trap so he can drain her life essence and put his cancer into remission. Monet's father notes that her life energy seems to attract "parasites" like Mordo and Monet herself directly compares Mordo to a vampire.
62** ''ComicBook/XMen'':
63*** Rogue 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]]. The Brazilian publishing emphasizes the vampiric metaphor, [[DubNameChange naming her as]] Vampira.
64*** Selene is a "psychic vampire" who can drain the LifeEnergy of human beings to sustain herself. If she drains the victim's entire life force their bodies crumble into dust. She can use absorbed life force to enhance her physical strength, speed, stamina, agility, reflexes, and durability to superhuman levels.
65[[/folder]]
66
67[[folder:Fan Works]]
68* ''Fanfic/AbraxasHrodvitnon'': After [[TwoBeingsOneBody fusing to Vivienne Graham]] to form [[AdaptationalHeroism Monster X]], [[Characters/AbraxasHrodvitnon San]] retains the ability to suck the energy and radiation out of opponent Titans with a bite that he had when he was part of Ghidorah, and he briefly uses this ability defensively and heroically against [[spoiler:[=MaNi=]/Elder Brother]].
69* 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.
70* 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.
71* ''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.
72* The ''Fanfic/EmpathTheLuckiestSmurf'' story "Smurfette's Inner Beauty" has Hogatha using the Spell of Syphonia, which drains Smurfette of her long life and beauty in order to give the evil witch a more youthful and attractive look. This goes on for hours until Empath's TrueLovesKiss breaks the spell and restores Smurfette's youth and beauty while also restoring Hogatha to her true age and looks.
73[[/folder]]
74
75[[folder:Films -- Live-Action]]
76* ''Film/ColorOutOfSpace2020'': Ezra speculates on his ApocalypticLog that the Color grows strong by feeding on what life it comes in contact with in the area.
77* ''Franchise/{{Godzilla}}'': Some incarnations of King Ghidorah are capable of this. [[Characters/GodzillaTheGhidorahs Keizer Ghidorah]] in ''Film/GodzillaFinalWars'' drains Godzilla's power with his bite, as does the [[Characters/MonsterVerseKingGhidorah MonsterVerse incarnation of Ghidorah]] in ''Film/GodzillaKingOfTheMonsters2019''.
78* ''Film/Lifeforce1985''. 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.
79* 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.
80* In the ''Film/XMenFilmSeries'', Rogue can do this through touch.
81* In ''Film/HocusPocus'', the three witches do this to a young girl to maintain their youth.
82[[/folder]]
83
84[[folder:Literature]]
85* The Others in the ''Literature/NightWatchSeries'' 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.
86** 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.
87** 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.
88*** 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.
89* 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.
90* Vardalek in Eric, Count Stenbock's ''Literature/TrueStoryOfAVampire'' appears to be what we'd recognize as a psychic vampire, gradually draining the life from his prepubescent thrall.
91* The weaponized variant of Vampiric Draining shows up in the ''Literature/{{Kull}}'' story "Riders Beyond the Sunrise", in which 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.
92* The dementors from the ''Literature/HarryPotter'' series.
93* 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.
94* In ''Literature/TheSecretsOfDrearcliffGrangeSchool'', "Shrimp" Harper has the ability to "breathe in" the life force of others, leaving them feeling tired and run-down. In the sequel, ''Literature/TheHauntingOfDrearcliffGrangeSchool'', she discovers that she has the ability to "breathe in" other things than life force, such as mental confusion or even arm-brokenness, and has the potential to be an EmpathicHealer.
95* ''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.]]
96* ''Literature/WonderWomanWarbringer'': Pinon can drain an opponent of blood and then "digest" it at her leisure to heal or power herself or Jason.
97* ''Literature/TheLicaniusTrilogy'': Thanks to his quasi-dead nature, Davian does not generate Essence as all other living things do. So in order to survive, he must leach small amounts of Essence from everything around him. Normally, the amount he drains from any one thing is inconsequential, but if he so chooses he can rapidly drain ''all'' the Essence from specific targets, causing them to crumble to ash.
98* ''Literature/CertainDarkThings'': The Revenant {{vampire variety|Pack}} have the unique power to drain or donate life energy with a touch. The donation can save a recipient's life and accelerate healing, albeit with excruciating pain; the draining causes victims to shrivel up and die -- in that order.
99* Ate from ''Literature/TheFaerieQueene'' is sustained by drinking the blood and sucking the life from those who succumb to stupid feuds and rivalries. She was born to feed this way by the demons who raised her.
100* ''Literature/MagicUniversity'': Sirens feed on human sexual energy, and if done too much this can put them into comas. This happens to Nichols and later Frost in the first book at the hands of [[spoiler:Michael]], though he didn't mean to.
101* ''Literature/UniversalMonsters'': In book 4, the trio learn that Imhotep is stealing blood from people, using a needle. In the original film, he never did so, leaving them confused about his motives; it later turns out it was meant to replace Anck-Su-Namun's dried-up blood.
102[[/folder]]
103
104[[folder:Live-Action TV]]
105* ''{{Series/Beyond}}'': The beings in the Realm appear to feed this way, as Frost ages rapidly when touched by one.
106* 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.
107* ''Series/InterviewWithTheVampire2022'': Vampires sustain themselves by exsanguinating humans, or animals if they're a [[VegetarianVampire vegetarian]], although the latter option isn't healthy because it's subsistence living.
108* The Fangire, and indeed most of the Demon Races seen in ''Series/KamenRiderKiva''.
109* ''Series/MotherlandFortSalem'': Adler remains young through draining youth from her biddies (who are volunteers).
110* 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). Whether a Wraith would die if they went without it is iffy, as they can hibernate for literally centuries if supplies are low. The only "starving" Wraith we ever see (because he was captured by humans) became delirious and started mixing poetry with prophecy.
111* ''Series/StarTrekTheOriginalSeries''
112** Episode "[[Recap/StarTrekS1E1TheManTrap The Man Trap]]". The creature on planet M-113 lives by draining all of the salt from other living creatures and thus killing them.
113** The cloud creature in "[[Recap/StarTrekS2E13Obsession Obsession]]" gains nourishment by draining the blood from human bodies.
114** The giant space amoeba in "[[Recap/StarTrekS2E18TheImmunitySyndrome The Immunity Syndrome]]" eats by draining LifeEnergy from all living beings within the cloud of darkness it generates.
115* ''Series/StarTrekTheNextGeneration''
116** "[[Recap/StarTrekTheNextGenerationS5E26S6E1TimesArrow 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.
117** In "[[Recap/StarTrekTheNextGenerationS6E3ManOfThePeople 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.
118** "[[Recap/StarTrekTheNextGenerationS7E13SubRosa Sub Rosa]]" reveals that a ghost-like energy being has done this to many generations of Beverly Crusher's family.
119* In ''Series/{{Supernatural}}'', [[Characters/SupernaturalDjinn the djinn]] drain blood or fear from their victims.
120* ''Series/SweetHome2020'': One of the monsters has a very long prehensile tongue which it uses to drain people's blood.
121* ''Series/TheTwilightZone1959'': In "[[Recap/TheTwilightZone1959S1E24LongLiveWalterJameson 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:She succeeds in draining our protagonist Jordan Herrick to death.]]
122[[/folder]]
123
124[[folder:Myths & Religion]]
125* SuccubiAndIncubi, 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.
126[[/folder]]
127
128[[folder:Tabletop Games]]
129* ''TabletopGame/DungeonsAndDragons'':
130** Cerebral parasites, thought eaters and brain moles feed on psionic energy, which can kill their victim.
131** Phthisics are evil beings [[{{Tulpa}} created by giving physical form to people's neuroses]], and survive by draining the intelligence of other creatures through their fangs.
132** 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.
133** [[OurVampiresAreDifferent Vampires]] feed on both blood (Constitution points) and life force (negative levels), while wights are weaker undead who drain life through slam attacks.
134** Alu-demons drain LifeEnergy by touching a living creature. Each touch drains 1-8 HitPoints and cures 1-4 HitPoints of damage the alu-demon has taken.
135** 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.
136** The 3rd level wizard/sorcerer spell Vampiric Touch drains health points from the victim to replenish lost health.
137** The 5e [[{{Dhampir}} dhampir]] player race is compelled to feast on one particular aspect of the living. This can be concrete elements such as blood or cerebrospinal fluid, or more [[AbstractEater abstract]] concepts such as dreams or generic "psychic energy". (Note that players are not required to have their characters act on these urges.)
138** Original ''D&D'' Supplement IV ''Gods, Demi-Gods & Heroes'':
139*** 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.
140*** In the Hyborian mythos based on Creator/RobertEHoward's ''Literature/ConanTheBarbarian'' stories, the Kraken feeds on human [[YourSoulIsMine souls]] and LifeEnergy from its victims. The deities Tsathoggus and Yezud and the monstrous Vampire Gorgon of Akhlat all consume LifeEnergy. The vampire vine sucks the blood out of its victims.
141** ''TabletopGame/DarkSun'':
142*** A thrax can drain all of the water out of an intelligent creature by touch. It can only drink water from a living creature, not normally. If it uses this attack on a human and the human survives, they may turn into a thrax themselves.
143*** ''Monstrous Compendium Appendix -- Terrors of the Desert'': The t'chowb can drain points of Intelligence by touch and add them to its own Intelligence rating, to a maximum of 24 points. The victim loses the Intelligence points permanently, but the t'chowb only gains them for one day.
144** ''Magazine/{{Dragon}}'' magazine #238: "The Return of the Wizards Three" descries the spell Scourge of Stars, which 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.
145** ''TabletopGame/{{Greyhawk}}'': In the adventure "The Lost Passage of the Suloise", the evil entity known as the Mother will drain the levels (LifeEnergy) of any creature inside its body.
146** ''Magazine/{{Dungeon}}'' magazine:
147*** Issue #31, ''TabletopGame/{{Ravenloft}}'' adventure "Bane of the Shadowborn'': The TabletopGame/{{Ravenloft}} Darklord sword Ebonbane sustains itself by draining the LifeEnergy of the living animals in its domain, killing them.
148*** Issue #41, adventure "A Way With Words": Vampire moss feeds on the LifeEnergy of all living things within ten yards, draining one HitPoint per minute. If a victim is reduced to half (or less) of its maximum HitPoints, it will eventually fall unconscious.
149** TabletopGame/{{Ravenloft}} setting
150*** 2nd Edition boxed set, "Realm of Terror" booklet: When someone fails a Ravenloft Powers check, one possible reward is gaining 3-6 points of Strength for 10 minutes (after drinking blood) once per day, and one possible penalty is being required to drink blood once per day with no benefit.
151*** ''Monstrous Compendium Appendix I'': The doppelganger plant can possess people using its mind bondage power and change them into podlings. It then drains 1-4 HitPoints of LifeEnergy from them per day until they die.
152* ''Magazine/{{Gygax}}'' magazine #3 adventure "The Marmoreal Dungeon of Garn Pat'uul". A vampiric cloud called a Horla can drain two HitPoints of LifeEnergy from all creatures inside its 15 foot diameter. Each two HitPoints drained heals 1 point of damage to the Horla.
153* ''TabletopGame/{{Shadowrun}}''. Many Awakened creatures have the Essence Drain ability, which allows them to drain Essence (life/magical energy) in order to restore the Essence they lose due to their Essence Loss weakness.
154* The Vampiric Bite and more generic Leech powers from ''TabletopGame/{{GURPS}}''.
155* 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.
156* ''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.
157* 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.
158* 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.
159* 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.
160* ''TabletopGames/LejendaryAdventures''
161** The Peccant permanently drain the Health (LifeEnergy) of human and humanoid victims and add it to its own health.
162** A Volitant Bruholak can do this too, but from any living creature.
163** A Nosferatu can do this by biting a victim, but keeps the Health only temporarily.
164** An Apparition can drain Speed (movement), Precision (dexterity) or Health by touch and temporarily add it to its own.
165** The Shadowling can drain Health and add it to its Health/Free Will for one hour.
166* ''TabletopGame/{{Rolemaster}}'' ''Shadow World'' supplement ''Jaiman: Land of Twilight'', adventure "Cult of the Third Moon". The Priestess of the title cult performs a human sacrifice ceremony at midnight in order to drain the LifeEnergy of the victim and maintain her immortality.
167* ''TabletopGame/CallOfCthulhu''. Several Franchise/CthulhuMythos creatures can drain blood.
168** Byakhee can drain blood by biting a victim. Each round thereafter the byakhee will drain 1-6 points of the victim's Strength until it reaches zero and the victim dies.
169** If a chthonian's tentacle hits a victim it inserts itself into their body and starts draining blood and other bodily fluids. This drains 1-6 points of Constitution per round from the victim. If a victim is hit by more than one tentacle each one drains 1-6 Con/turn. The lost Constitution cannot be regained. When the victim reaches zero Constitution it dies.
170** When a Dark Young of Shub-Niggurath grabs someone with a tentacle, it holds the victim to its mouth and drains 1-3 points of Strength per round. The lost Strength cannot be regained.
171** Shub-Niggurath drains victims with its mouths the same as its Dark Young, but drains bodily fluids at a rate of 1-6 points of Strength per round.
172** After a star vampire grabs a victim with its talons it can bite and drain blood from it at a rate of 1-6 points of Strength per round.
173** If hungry, Tsathoggua holds a victim against his body and drains 1 point from each of the victim's characteristics (Strength, Constitution, Size, Intelligence, Power, Dexterity, and Appearance. Each full month of hospital care restores 1 point to each characteristic.
174** Early versions of the rules had regular vampires. Their bite could drain 1d6 Strength points of blood per round.
175* Classic ''TabletopGames/{{Traveller}}''
176** ''Journal of the Travellers' Aid Society'' #4. Since the Reticulan Parasite (based on the ''Franchise/{{Alien}}'' xenomorph) doesn't eat the bodies of the creatures it kills, it's been speculated by biologists that it uses the victims' LifeEnergy to sustain itself.
177** Judges Guild adventure ''Darthanon Queen''. The randomly created Dyson monster could regenerate damage by absorbing the LifeEnergy of the humans it killed.
178* Fantasy Games Unlimited's ''TabletopGame/{{Aftermath}}''. Vampires are human beings mutated by biological agents or radiation. They consume blood drained from captured humans.

182* ''Man, Myth & Magic'' Book III ''The Adventures Book'', adventure "The Great Pyramid Revealed". While exploring the Great Pyramid in Egypt the {{PlayerCharacter}}s will encounter a room filled with rare underground plants called Indego Gentian. The plants use any creature that enters the room as food, draining both Power (magical energy) and Life Points (LifeEnergy) from them.
183* ''TabletopGame/RuneQuest''
184** Supplement ''Dorastor: Land of Doom''

189* ''TabletopGame/{{Arduin}}'' RPG, ''The Compleat Arduin Book 2: Resources''
190** Demons

192*** The Greater Demon Apharoe the Star Witch can drain the soul of a victim by kissing them for two consecutive melee rounds.
193*** The Greater Demon Sl'yth the Nightmare Demon can use its psychic powers to suck another creature's flesh off its bones and devour it. If the victim dies from this Sl'yth will also consumes the victim's soul.
194** The Drich undead are evil beings that survive by drinking the blood and eating the hearts of living, sentient beings during a horrible ritual. Each victim sustains them for a week, so they spend all their time hunting down new ones.
195** The Lich undead must drain the LifeEnergy of a sentient being at least once every 13 day Arduin lunar cycle or become unable to move (but it can still think).
196** Rakshasha (sic) can rend with their claws and bite with their fanged jaws. While doing so they psychically drain and devour their victim's soul.

210** A dense fog will manifest an evil strangling mist that feeds on the LifeEnergy of creatures it kills to sustain itself.
211** The {{PlayerCharacter}}s may be led astray by a glowing light that lures them into deathtraps. Once they're trapped the [[WillOWisp Will o'Wisp]] will return and touch them to drain their LifeEnergy as they're dying.
212* ''TabletopGame/NightLife'': Nearly every monstrous species of PC has some variant of this trope, as draining victims of whatever one's monster-type needs -- blood, vigor, youth, whatever -- is the usual method of restoring one's own health and/or staving off HorrorHunger.
213* ''TabletopGame/InNomine'': Impudites, a type of demon, feed by consuming the Essence -- spiritual power -- of other beings, primarily humans.
214* ''TabletopGame/TheUnofficialHollowKnightRPG'': Any character with the Bloodsucker trait is able to drain blood from other creatures in order to feed themselves. This is useful for stretching out the party's food supplies and getting around disadvantages from the Carnivore and Herbivore traits - even if there's no food that the bloodsucker can eat, they can just drain nutrients from their allies who don't have such restrictions on their diet.
215[[/folder]]
216
217[[folder:Toys]]
218* ''Toys/{{Bionicle}}'':
219** Gorast, after exposure to Pit Mutagen. Not surprisingly, given her mosquito-like appearance.
220** Also Krika, who had to drain body heat from living things to stay alive.
221** Anyone who wears the Kanohi Avsa, the Mask of Hunger; the only one in the main story is Vamprah.
222[[/folder]]
223
224[[folder:Video Games]]
225* ''VideoGame/{{Metroid}}'': Metroids feed on life energy and leave their victims as desiccated husks. At least one specimen is able to [[InvertedTrope inject energy into others]], too.
226* ''[[VideoGame/UltimateSpiderMan2005 Ultimate Spider-Man]]'': Venom needs to absorb his victim's energies.
227* ''VideoGame/KnightsOfTheOldRepublicIITheSithLords'':
228** The HumanoidAbomination Darth Nihilus feeds on the LifeEnergy of others through the Force to sate his endless hunger. He has done this to ''[[PlanetEater entire planets]]''. The PlayerCharacter is revealed to function in a similar manner, as after losing their connection to the Force they begin to draw upon it through others. Your KarmaMeter determines whether this symbiosis is [[PowerParasite parasitic or mutualistic]]. In the third game ''VideoGame/StarWarsTheOldRepublic'', TheEmperor is shown to have a similar power to Nihilus but still retains some of his "humanity".
229** The Force drain family of powers allow normal DarkSide users to do this on a much smaller scale, draining the LifeEnergy or ManaMeter of opponents to replenish themselves.
230* ''VideoGame/DarkSouls'': The Dark Hand uses the Dark Soul of the Undead to drain humanity in its grab attack. Can be used a limited number of times on [=NPCs=], too.
231* ''VideoGame/BloodKnights'': The player character Alyssa, a vampire, uses this ability to LifeDrain her enemies and restore her health. An early vampire boss (also a HealingBoss) can do this too, though not to Alyssa - instead, her arena is filled with caged prisoners, and she'll drain her captives' life to boost her own periodically.
232* ''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!
233* ''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.
234* ''VideoGame/StarCraftII'': This is the fundamental play style of Alarak. He actively heals himself by either killing his own units or enemy units, and won't survive long without doing so.
235* ''VideoGame/EldenRing'': The Deathbed Companions are a positive example; they can drain LifeEnergy through hugs, which they use to MercyKill people on their deathbeds in a soothing manner. The player meets one such companion named Fia, who offers a hug and a temporary boost to the Poise stat in exchange for a temporary 5% health reduction.
236* ''Franchise/TheElderScrolls''
237** 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.
238** 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.
239** ''VideoGame/TheElderScrollsVSkyrim'': In the ''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]].
240* ''VideoGame/EndlessLegend'': The Broken Lords were once a faction of noble human warriors and knights who transformed themselves into living armor in order to survive the collapsing climate of Auriga. This resulted in them requiring [[AppliedPhlebotinum Dust]] to survive. They can refine and consume naturally-occurring Dust, but another source is draining it from the bodies of living beings, a process that harms and eventually kills them. While honor dictates that they use the former method, [[EvilFeelsGood the latter is far easier, faster, and much more pleasant]].
241* ''VideoGame/Infamous2'': The Bio Leech attack lets Cole drain the bioelectric energy of the Militia. Bio Leeching gives you Evil {{Karma|Meter}} for it and [[EvilFeelsGood the satisfaction]] of [[HorrorHunger monstrous Conduit gluttony]].
242* ''VideoGame/BugFables'': One of the side-quest bosses is Monsieur Scarlet, an ant criminal who lures adventurers into his lair with [[WoundedGazelleGambit false help requests]] on quest boards, and then kills them via draining out their life force. He came dangerously close to doing this with Levi and Celia until [[PlayerCharacter Team Snakemouth]] puts an end to it. During the battle, he can also [[LifeDrain heal himself by attacking a party member]].
243* ''VideoGame/KhimeraPuzzleIsland'': The mastermind of the whole game clarifies their feeding habits, instead of physical comsumption, it's the extraction of LifeEnergy:
244-->'''Aylith:''' I'm not going to eat you, like, in the literal sense.\
245[...]\
246I'm just going to drain your life energy, leaving your body behind as a lifeless husk!
247* ''Franchise/MegaMan:''
248** Shade Man in ''VideoGame/MegaMan7'' and Dark Necrobat (Dark Dizzy) in ''VideoGame/MegaManX5'' both have an attack that restores their own health by draining it from a target.
249** Mercury in ''VideoGame/MegaManV'' has an unusual form of this, stealing items from an opponent with his Grab Buster, or converting energy from them into energy pellets to restore himself. By PowerCopying the Grab Buster, Mega Man can do it too.
250* ''VideoGame/{{Warcraft}}'':
251** ''VideoGame/WarcraftIIIReignOfChaos'': Vampiric Aura is a passive ability seen on high-end Undead units and the LooksLikeOrlok Dreadlords which allows friendly melee units to heal damage every time they attack an enemy. The Vampiric Potion gives a similar but temporary effect to the hero that uses it.
252** ''VideoGame/WorldOfWarcraft'': High Elf offshoots have a very bad habit of falling into magical addictions that require this kind of treatment if they get separated from their sources of power.
253*** In ''Burning Crusade'' which debuted the Blood Elves/Sin'dorei as a playable race, they were desperately seeking to find a replacement for their recently destroyed Sunwell and would suck mana energy out of nearly anything that could give it to them, effectively making them mana vampires. However this part of their characterization was dropped at the end of the same expansion, when the Sunwell was restored and their addiction was cleansed, though they would keep the ability to mana tap for a few more expansions before it was removed for not making sense with the story.
254*** Darkfallen/San'layn are Blood Elves who died during Kael'thas' march to try to kill Arthas back in Warcraft 3 and were resurrected as Elven Vampires and cursed with the traditional hunger for blood. Every time one is fought, they have an attack to either drain your energy, or pin you down and directly drain your blood.
255*** Void Elves/Ren'Dorei introduced at the tail end of Legion are Blood Elves who have been touched by the power of the void, an entropic force of nothingness. Besides HearingVoices and having to struggle constantly against falling to the insane whispers in their head, it's also mentioned that being touched by the insatiable, ever-hungering darkness of entropy has once more cursed them with a desire to drain life energy from living things. However, unlike Blood Elves' mana tap, there's no racial skill that reflects this.
256*** And finally there are Venthyr, keepers of the Afterlife of Revendreth in Shadowlands. It's not even kept subtle that they're vampires, they [[LooksLikeOrlok Look Like Orlok]] and pretty much every one of them has some form of life drain attack. However, in their case it's not blood, but anima -- the energy of the soul -- that they drain as harvesting it from souls they're redeeming and feeding it back to their realm and others' is what keeps the rest of the Shadowlands running.

259[[folder:Visual Novels]]
260* ''Franchise/{{Nasuverse}}'':
261** The True Ancestors, who go insane if they completely abstain for too long, but don't actually ''require'' it for sustaining themselves; the addiction is purely psychological.
262** The Dead Apostles, however, require blood for physical sustenance, making them closer to the classical vampires in this regard.
263** Rider from ''VisualNovel/FateStayNight'', who is decidedly '''not''' a vampire, but rather [[spoiler:a Gorgon (namely, Medusa)]].
264** Servants in general can drain people's life force to sustain themselves if they can't get sufficient mana from their Master, though most of them will refuse to do it on moral grounds (they are ''Heroic'' Spirits, after all).
265* [[VampireWannabe Wilhelm Ehrenburg]] from ''VisualNovel/DiesIrae'' and its [[VisualNovel/DiesIraeInterviewWithKazikluBey prequel]] is able to create a field of effect where all life is slowly drained and fed to him. Even inanimate objects start to decay and break down if caught in it for too long. It additionally also turns him closer to a true vampire with all the same perks and drawbacks as a real one would have. And fittingly, the field is also crowned by a [[BadMoonRising blood red moon]] when it is activated.
266[[/folder]]
267
268[[folder:Webcomics]]
269* The creatures in the Shocking Horror arc of ''Webcomic/BreakpointCity'' (begins [[http://www.breakpointcity.com/archives/2003/09/24/screaming-skull/ here]]) do this via spikes through the forehead.
270* 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.
271* ''Webcomic/{{Earthsong}}'': The "vampire" species normally [[http://www.earthsongsaga.com/vol2/109.html drink blood]], but those with soulstone power can [[http://www.earthsongsaga.com/vol2/87.html feed]] on LifeEnergy instead. FriendlyNeighborhoodVampire Tristram can also drain [[VegetarianVampire plants]] and can heal people by [[LiquidAssets transferring life energy into them]].
272* In ''Webcomic/{{Endstone}}'', [[http://endstone.net/2010/01/14/issue-3-webpage-9/ Cole can do this.]]
273* This has appeared ''a lot'' in ''Webcomic/TheOrderOfTheStick'' 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.]]
274* In ''Webcomic/ElGoonishShive'', being possessed by a body-snatching Aberration has this effect.
275* ''Webcomic/LotusCobraIsEvil'': From [[https://i.imgur.com/NbfiL1f.jpg "Favorite Zendikar Card"]]: Referenced with Sorin Markov, Vampire Lord's favorite card being "Feast of Blood".
276* ''Webcomic/{{Unsounded}}'': Efheby envenom human victims and then drink their soul and memories. If they're careful their victims can mostly recover from a couple of bites, but after enough bites the tattered remains of their soul won't fit together anymore and they'll lose their mind and die no matter how careful the efheby is.
277* 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.
278[[/folder]]
279
280[[folder:Web Original]]
281* 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.
282* ''Website/SCPFoundation'':
283** [[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.
284** [[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 them and drain them of all of their blood in a few minutes.
285** [[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.
286** [[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.
287** [[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.
288** [[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.
289** [[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.
290** [[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.
291** [[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 desiccated, malnourished, and 73% likely to die.
292** [[http://www.scp-wiki.net/scp-3359 SCP-3359 ("The Dry Guy")]]. Victims of SCP-3359 are transformed into walking [[{{Mummy}} mummified corpses]] that instinctively seek out the blood of the living to (temporarily) return to their former state. They are capable of draining bodily fluids of living creatures through their skin by touch alone, and when a "rehydrated" one is asked why they don't just simply use water he equates it to eating dirt.
293** [[http://www.scp-wiki.net/scp-5721 SCP-5721 ("What Passes As Worship In The Digital Age")]]. The messaging app Discord, of all things, which drains users' LifeEnergy for the [[Myth/ClassicalMythology Greco-Roman goddess Eris]] thanks to [[ReadTheFinePrint a clause in the TOS giving her permission]]. [[JerkassGods Good luck trying to sue a deity.]]
294[[/folder]]
295
296[[folder:Western Animation]]
297* ''Franchise/Ben10'':
298** Michael Morningstar, first appearing in ''WesternAnimation/Ben10AlienForce'', can drain the LifeEnergy from his victims.
299** ''WesternAnimation/Ben10Omniverse'': Vladats such as Lord Transyl can naturally do this, as can the Omnitrix's Vladat DNA sample [[Characters/Ben10OmnitrixAliens Whampire]] although Ben tries to resist the urge when he turns into him.
300* ''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.
301* ''Franchise/MyLittlePony'':
302** ''WesternAnimation/MyLittlePonyAndFriends'': The witch Somnambula retains her youth by sucking the life out of others, and drains the magic from unicorns to enhance her own power.
303** ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
304*** Changelings feed by draining ponies of their love. They even have fangs to complete the vampiric look, the show's time slot won't allow for any graphic biting, however. The IDW comics tame this a little further. [[http://i29.photobucket.com/albums/c282/Hyaroo/MLPFIM_3_TheGroup_006_zps5b02e8c1.jpg?t=1360615219 Take a gawk.]] [[spoiler:They get better after discovering they can feed by simply sharing love with each other.]]
305*** Lord Tirek grows stronger from draining other living creatures of magic, and he specifically cannot absorb magic fron inanimate objects. When overdosed on magic, he loses all control and turns into a raging beast.
306*** The Dazzlings, a band of Sirens from ''WesternAnimation/MyLittlePonyEquestriaGirlsRainbowRocks'', feed on negative energy, as well as enchant people with their singing, turning them into mindless drones. They seek popularity to gain the possibility to turn more people against each other, becoming more powerful.
307* Gigabyte, a powerful virus from ''WesternAnimation/{{ReBoot}}'' has one oversized claw that he uses to drain the energy from his victims, in an attempt to restore himself to full power.
308* 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.
309* Rather than draining people of their blood like in most other versions, in ''[[WesternAnimation/UltimateSpiderMan2012 Ultimate Spider-Man]]'' Michael ComicBook/{{Morbius}} drains people of their LifeEnergy.
310* In the ''Literature/StarDarlings'' cartoon, BigBad Lady Rancora can drain positive energy and turn it into negative energy in order to empower herself, with extreme drainage being lethal to her victims.
311* In ''WesternAnimation/BarbieAndTheSecretDoor'', Malucia's magic scepter can drain other beings of their magic and leave them powerless, with her end goal being to capture all of Zinnia's magic.

314[[folder:Real Life]]
315* Vampire bats are ExactlyWhatItSaysOnTheTin.
316* 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.
317* 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.
318* Spiders to a point, as they are unable to eat solid food. After killing their prey with venom, even if there's some evidence spider venom often [[AndIMustScream just paralyzes the victim instead of killing it]], they will pump out digestive fluid into the wound and will suck the liquefied entrails with most species leaving an intact husk behind when they end feeding.
