A form of HollywoodScience where it's possible to, in effect, "drain", or "transfer", or "reverse" physical conditions.

The usual form this takes is related to LifeEnergy-- [[LifeDrain if you drain someone's life energy]], they start to show the physical signs of aging. Transferring life energy ages the victim and [[LifeDrinker youthens the recipient]]. This treats aging as if it's the presence or lack of a substance. With right the set of in-universe rules, this becomes both possible and reasonable with the right kind of FunctionalMagic or AppliedPhlebotinum.

A variation simply has characters "aged" or "youthened". There's no actual drain or transfer, but age is still treated as a substance, where it can be added or removed and you'll automatically get a whole host of physical changes. This can be extended to where someone is [[FountainOfYouth youthened into a baby]], or a [[OvernightAgeUp baby aged into an adult]].

It is sometimes used for FairestOfThemAll. It may also be a PowerSource to some villains or powers, or as the food for HorrorHunger. If the character is using this to live forever, it's LifeDrinker. It helps when you use PowersAsPrograms. EmpathicHealer is a more heroic inverse of this trope, where someone ''heals'' another person by transferring the other person's wounds to themselves. The assets may be acquired via a BloodBath. {{Level|Drain}} and LifeDrain are both Tabletop and Video Game sub tropes.

Not to be confused with PooledFunds.

!!Examples

! '''Transfer or drain for aging'''

[[AC:{{Anime}}]]
* One of the [[MonsterOfTheWeek monsters of the week]] in ''{{Zanki}}'' used leeches to drain the blood of schoolgirls, leaving them withered husks and making herself young and beautiful in the process.

[[AC:Comic Books]]
* MarvelUniverse villan Selene, in her earlier appearances in ''NewMutants,'' was an energy vampire; as she sucked the life out of her victims she became ever more young and beautiful; as she used her powers more, she would look older.

[[AC:{{Film}}]]
* The movie ''Film/{{Lifeforce}}'' and the book it was adapted from, ''The Space Vampires''.
* In ''Film/IndianaJonesAndTheLastCrusade'', the knight guarding the Holy Grail explains that, "The true Grail will give you life, and the false Grail will take life from you." When Donovan drinks from the wrong Grail, he ages rapidly until he dies, his body decomposes and turns to dust. Notable for the fact that Donovan grows a considerable amount of hair during the ageing process, and may well have died of starvation for all we know.
* In ''Film/ThePrincessBride'' Wesley has at least 31 years of his life drained away to the point that he's OnlyMostlyDead.
* Featured in the [[Series/MysteryScienceTheater3000 MST3K]] classic ''Film/MerlinsShopOfMysticalWonders'': the {{Jerkass}} subject of one story makes liberal use of a book of magic spells, but finds that afterwords he's suddenly been turned into an old man, since magic use drains LifeEnergy. His solution is to use the book's recipe for a LifeEnergy-restoring potion, but winds up overdoing it (or something) and turning himself into a baby.
* ''Film/XMen'':
** Used partially in ''Film/XMen1''. After Rogue (having absorbed a large part of Magneto's power) is used as a battery for the machine that gives normal people powers, she becomes drained of energy, and her hair gets [[LockedIntoStrangeness a grey streak]]. In fact, Magneto used her for this because using it was expected to ''kill'' the user.
** In ''Film/TheWolverine'', Yashida intends to drain Logan's HealingFactor from him.
* In ''TheDarkCrystal'', captive Podlings are drained of their "living essence" in order to provide the Skeksis with mindless slaves. Drinking the essence gives a temporary "youth boost", at least in appearance. Very temporary. "It always worked better with gelfling..."
* In the 2002 ''[[Film/TheTimeMachine2002 The Time Machine]]'' film, [[spoiler:the Morlock leader]] gets partially thrown out of the time machine in overdrive and rapidly ages, similar to the Indiana Jones example above. This is even more strange, as this means he was basically hanging for centuries without trying to do anything about it. Actually, his hands should've been cut off the moment he left the temporal bubble.

[[AC:{{Literature}}]]
* Notably averted in the Creator/LarryNiven book ''A World Out of Time''. Aging is dependent on cellular poisons that can be removed. However, people who have it removed don't instantly turn young, but gradually get young as their younger cells can repair the body.
* Magic in the ''Literature/{{Hurog}}'' duology works like this. Ward, who has magical abilities, but is untrained, can share his magical energy with Oreg, who is better at doing something with it.
* Most magic in ''Literature/TheRunelords'' books operates on this principle.
* In ''Literature/{{Dracula}}'' and in a few of the numerous adaptations, the Count starts off as an elderly man and becomes younger in appearance over time through drinking blood. Also, when Lucy becomes a vampire, she looks healthier "dead" in her coffin than she did alive.
* [[EvilSorcerer Fistandantilus]] of ''Literature/{{Dragonlance}}'' routinely drained the life-force from one of his apprentices to maintain his immortality, and from the description of the process it also seems to restore at least some of his youth. [[EvilOldFolks He still looks impossibly ancient most of the time]].
* In Creator/RobertEHoward's ''Franchise/ConanTheBarbarian'' story "Literature/RedNails", Tascela does this. She intends to do it to Valeria.
* The second book in the ''SwordOfTruth'' series has this as a major plot line - evil sorceresses drain the power of wizards and add it to their own.
* Happened to Wesley in the ''Series/{{Angel}}" tie in novel "The Longest Night" from a spell being used by a desperate, dying father who was trying to stay alive to see his son grow up. Angel rescues Wes and the boy is briefly aged by the spell, thereby letting the dad see him as an adult before he returns to being a kid.

[[AC:{{Live-Action TV}}]]
* The Wraith on ''Series/StargateAtlantis''. It was {{handwave}}d as "a series of complex chemical processes that we only barely understand." This, however, [[VoodooShark does not explain]] how the victims suddenly grow enough extra skin to be wrinkly like that.
** This can be covered by their body rapidly going through an accelerated aging process, so it still makes more sense than their hair turning grey/white.
** Rather than growing extra skin, couldn't they be losing muscle and bone mass? That could even help explain where Wraith get chemical nutrients.
* ''Series/StarTrekTheNextGeneration'' episode "Man of the People: An ambassador uses Troi as a dump for all his negative emotions, which in turn ages her rapidly.
** When the effect was undone, Troi immediately reverted to her younger self, including her grayed hair returning to black.
** And it happened to Dr. Pulaski when her aging disease was cured, only justified as the [[TeleportersAndTransporters transporter]] basically restructured her body.
* ''Series/PowerRangersDinoThunder'' had a MonsterOfTheWeek who "stole youth" to be used as a power source, leaving victims elderly. Since ''Rangers'' monsters suffer from NoOntologicalInertia, taking the monster out caused everyone to turn young again.
** Similarly, ''Series/KamenRiderDouble'' had a [[MonsterOfTheWeek Criminal Of The Week]] with aging powers who sold his services (primarily to {{Stage Mom}}s); once his [[AppliedPhlebotinum Gaia Memory]] was destroyed, all his victims returned to normal.
* One episode of ''Series/{{Farscape}}'' involved a [[ProudWarriorRace Luxan]] holy woman undergoing a psychic ritual with D'Argo, which unexpectedly resulted in her becoming far younger, because she was accidently draining energy from [[SpaceWhale Moya]], who underwent accelerated aging.
* In the ''Series/{{Heroes}}'' online material, Linda Niles [[spoiler:a.k.a. Leona Mills]] has this as her superpower. She also suffers from accelerated aging if she doesn't use this power regularly. However, she's a ''protagonist'', so she only drains youth from trees and pieces of wood rather than people.
** Additionally, in the main series, when [[spoiler:Adam]] loses [[spoiler:his]] healing factor [[spoiler:Or, more accurately, when Arthur Petrelli drains it from him, he ages super-rapidly and crumbles into dust]]. Apparently, healing factors in the Heroes 'verse merely suppress the symptoms of aging rather than reversing them or making them never happen at all.
* ''Series/BabylonFive'' features an alien artifact that transfers life energy. It can be used to heal illnesses, wounds, etc., but does not visibly alter the age of either the donor or the recipient.
* In the ''Series/{{Smallville}}'' episode "Redux" the [[MonsterOfTheWeek Freak of the Week's]] power to absorb life energy immediately becomes apparent as the victim rapidly ages.
* The ''Series/WarehouseThirteen'' Season 2 episode "Age Before Beauty" has Myka become an UndercoverModel to track down an ArtifactOfDoom that's causing other models to age to death. [[spoiler:The culprit reverts to an old man when he's HoistByHisOwnPetard.]]
* In ''Series/LoisAndClark'', an evil scientist drains Jimmy Olsen's youth to rejuvenate herself.
** Bonus points in that old Jimmy was a cameo by Jack Larson, who played Jimmy Olsen in ''Series/TheAdventuresOfSuperman'' in the '50s.

[[AC:WesternAnimation]]
* The 1990s ''WesternAnimation/SpiderManAndHisAmazingFriends'' has an arc based around this, with elderly villain Silvermane trying to become younger via magic and winding up turning himself into a baby. The Vulture constantly shifts between youthful and elderly form, eventually managing to stabilize himself as young by taking Silvermane's youth via the AppliedPhlebotinum meant to restore him to adulthood (thus returning Silvermane to his original elderly form). Later, Venom and Carnage are recruited by a villain to steal LifeEnergy to release a SealedEvilInACan. This results in rapid aging.
* ''MyLittlePony'' had a one-shot villain, a witch named Somnambula, create a carnival as a trap for the Ponies so she could drain their youth and the unicorns' magical power to herself.
* The villain Mad Mod in ''WesternAnimation/TeenTitans'' used a magic cane in his second appearance to suck the youth out of Robin and into him. He then proceeded to rule over reality (or at least one city's worth of it) like a [[Music/TheBeatles Beatles]] - and ''Creator/MontyPython''-obsessed God until the Titans put him back in his place.
** ... that'd sounds like a pretty awesome god, actually.
*** Until he starts crushing people with the GiantFootOfStomping, or forcing people to play in the UpperClassTwit games, at least.
** It also sucked the youth out of Robin's ''clothes'' turning them into old and worn-out with faded colors, and made Mad Mod's clothes regain their color and look new again. What's the name for that trope?

! '''Transfer or drain for wounds'''

[[AC:{{Anime}} and {{Manga}}]]
* ''Manga/BusouRenkin'': The special ability of Ouka Hayasaka's bow weapon is that she can craft arrows that transfer wounds to herself. She uses them twice: once on her brother, and once on Kazuki.
* In ''Manga/OnePiece'', Bartholomew Kuma is able to push EVERYTHING with his hands. Sounds useless, right? He can push even physical conditions out. So far, it has been shown only with pushing pain [[spoiler:out of Luffy,]] which manifested as a giant red bubble. [[spoiler:It then made a viable projectile, with a small bit of the bubble knocking Zoro to his knees. And then he took it all in. [[MadeOfIron This trope's image]] is the end result. You can't see it in the picture but he is more or less unconscious. While standing.]] The wounds weren't healed, but the 'donor' felt great after waking up.
* If you use magic to heal someone in ''Anime/OjamajoDoremi'', their wound is transferred onto you. This is why healing magic is forbidden, as is magic that brings people BackFromTheDead.

[[AC:ComicBooks]]
* MarvelComics' most recent attempt at an ongoing series for Rogue took her absorption power to a ridiculous extreme; when she touches Juggernaut to absorb his powers while he is having a heart attack, she ''absorbs the heart attack.'' In a subsequent issue, she accidentally touches Gambit who is temporarily blind because of an eye injury, and is also struck temporarily blind until the absorption wears off. [[note]]''ComicBook/{{X-Men}}'' #179, when she absorbs Colossus's steel form after he'd been paralyzed by the stress of being near-melted and then frozen in a tag team attack; despite it being the results of external attacks rather than natural powers, she assumes the paralyzed form. (Not to mention ''every time'' she absorbs Cyclops's powers, since the lack of control necessitating his visor was the result of an external injury rather than being inherent to his power).[[/note]]
* ComicBook/{{Raven}} of the ''ComicBook/TeenTitans'', at least in her comic book incarnation, "absorbs the pain" and apparently the physical wounds of whomever she heals. In one memorable scene, when her demon father Trigon put the "death stare" whammy on a little girl for being too childishly honest, Raven absorbed the "blood boiling" injuries from the child in a very painful-looking scene, becoming covered with welts and blisters until she could heal herself as well. [[CruelTwistEnding Then Trigon vaporized the kid anyway]].

[[AC:{{Film}}]]
* In ''Film/XMen1'', Wolverine lets Rogue absorb his healing factor to save her, and instead of his healing merely being halted, his already-healed wounds ''returned.''

[[AC:{{Literature}}]]
* ''Literature/BrokenSky'' does this with those that possess the yellow spirit stones, the healers. They can take on the injuries of another, whether the injury is mental or physical in nature. While they heal faster than most people, an inexperienced or reckless healer could kill themselves quite easily by absorbing more wounds than their body could handle.

[[AC:{{Live-Action TV}}]]
* In the ''Series/{{Torchwood}}'' episode "They Keep Killing Suzie", the resurrection gauntlet, when used with enough empathy on the revived person (a normal resurrection lasts one or two minutes), transfers the fatal injury to the user of the gauntlet. When the connection broke, the injuries leave.
* In the ''Series/BabylonFive'' episode "The Quality of Mercy", an alien device used by a disgraced human doctor transfers life energy between the people attached to it. [[spoiler: The device was actually for executing criminals, a use to which it gets put by the end of the episode.]]
* This proves to be Chloe's GreenRocks-given power in ''Series/{{Smallville}}.'' Her first use of it left her clinically dead for a long time, and her second left her with a finger cut in the same manner as Jimmy's had been when she healed him.
* In ''Series/{{Heroes}}'' when the [[FanNickname Wonder Twin]] heals people infected with his sister's illness not only do they get healthy, but their black tears somehow disappear.
* In the ''Series/{{Star Trek|The Original Series}}'' original episode "The Empath", the titular mute alien could heal others, but suffered concurrent damage to herself. If she healed someone badly enough injured, she could die.
* A similar example in ''Series/TheXFiles'', wherein a monster would [[spoiler:eat people, and later vomit them out again into a mold where they took their original human form after a time]]... this had the effect of healing the people entirely, but passing all the symptoms onto the monster. The monster thus stacked up symptom after symptom, a living hell, until finally he [[spoiler:ate John Doggett]], who was dead at the time, thus passing the death onto the monster, who was finally free of the pain of disease-ridden life.

[[AC:TabletopGames]]
* In the game ''[[TabletopGame/SeventhSea 7th Sea]]'', there is an advantage in the Vendel/Vesten sourcebook called "Sympathetic Healer" that allows a player to absorb another's wounds into themselves. Likewise, they can transfer injuries into a target if pressed.
* ''TabletopGame/DungeonsAndDragons'' (from AD&D 2 on) wizard spell "Vampiric Touch" (drains HitPoints).
** PsychicPowers "Life Draining" (drains HitPoints) and "Psychic Drain" (gains power points by temporarily damaging the victim's stats), 3 ed. has "Psychic Vampire" (drains power points, if the victim has none it damages stats temporarily).
** ''TabletopGame/ForgottenRealms'' has wizard spell "Morgannaver's Sting" (stronger variant of Vampiric Touch) and in 3rd ed. druid spell "Healing Sting"
** The {{Ps|ychicPowers}}ionic ability "Lend Health" from the second edition's ''Complete Psionics Handbook'' likewise works by way of literally transferring injury from the recipient to the psion using the power.

[[AC:WebOriginal]]
* Kerry Ellison (Seraphim) of the WhateleyUniverse. When her powers manifest, she finds she can heal people but only by getting their injury/illness for a while. And the injury/illness from previous healings at a lessened level. Which means that when she heals an old woman with cancer, she's in agony for hours. And then she's ''forced against her will'' to heal person after person, taking on all their illnesses. {{Squick}}.
* [[SCPFoundation SCP-]][[http://scp-wiki.wikidot.com/scp-590 590]] is an empathic healer who follows this trope. When he heals someone's serious physical injury, he feels the pain they felt when they received the injury, and a scar appears on his body to correspond with the injury's location on the individual being healed. Unlike most empathic healers in fiction, he doesn't have an accelerated healing factor, so the damage he heals constantly accumulates in his body. When the Wiki/SCPFoundation took him in, they had him heal several cases of mental retardation, permanently leaving him with the intelligence of a three-year-old child, thereby making him less able to resist his new role as the foundation's repository for suffering. It's also treated as a partial MercyKill: ''hopefully'' there's not enough of his mind left to properly suffer all that agony.
* King of the Slaughterhouse Nine from WebOriginal/{{Worm}}, who can transfer his injuries to anyone he has touched in a 24 hour period.
** The similarly powered Scapegoat can absorb other people's injuries and then transfer them to his opponents. Unfortunately for him, he fully experiences any injuries he's carrying until he can load them off.

[[AC:WesternAnimation]]
* In ''WesternAnimation/AdventureTime'', Xergiok the ex-Goblin King heals an accidentally-broken leg of one of his birds by using a "vibrational chant" (which isn't magic, according to him) to give the bird his healthy leg and transfer the bird's broken leg to himself. [[spoiler: He then does it again to steal one of Jake's legs and its stretching ability, leaving Jake with the bird's broken leg.]]

! '''Aging/youthening without explicit transfer'''

[[AC:{{Anime}} and {{Manga}}]]
* Isumi's great grandmother of ''Manga/HayateTheCombatButler'' is able to suck the blood of a target who is 'near death' to restore her youth. Isumi is hinted at having the same ability, but she's only 13, so it wouldn't have any effect.

[[AC:{{Literature}}]]
* L.E. Modesitt Jr.'s, ''Literature/TheSagaOfRecluce'' series has order and chaos magic. Natural aging is a breakdown of order in the body and an increase of chaos, which can be countered by using magic to restore and reinforce order to a person's body. While this makes a person healthier (and an order master is effectively immortal), it also causes cosmetic changes that make little sense, like gray hair returning to the person's natural color. In the first book, a secondary character goes from black to gray to black hair repeatedly while straining himself or using too much chaos magic, then recovering.
* In the ''Literature/DragonJousters'' series by MercedesLackey, the Magi were deliberately encouraging the war between Alta and Tia to continue, since they were using the death of the soldiers fighting in it to extend their lifespans and that of the Altan rulers. Later on, Magi that were forced to flee Alta went to Tia and did the same for the Tian king. Also, the Magi were draining the priests/acolytes that were 'god-touched' in order to power their spells, which eventually killed the priests/acolytes or stripped them of their powers.

[[AC:{{Live-Action TV}}]]
* The Master ages the Doctor 900 years while suspending his [[TheNthDoctor regenerative]] capability in the ''Series/DoctorWho'' episode "Last of the Time Lords".
** Being a show about time travel, many stories in the old series (like "[[Recap/DoctorWhoS9E5TheTimeMonster The Time Monster]]", "[[Recap/DoctorWhoS18E1TheLeisureHive The Leisure Hive]]" and "[[Recap/DoctorWhoS17E2CityOfDeath City of Death]]") had people aging and de-aging without any negative side affects (besides being older).
* This happened to Martha temporarily when [[TheGrimReaper Duroc]] almost took her in the ''Series/{{Torchwood}}'' episode "Dead Man Walking".
* The various ''Franchise/StarTrek'' series have had instances of rapid aging caused by diseases, etc. During a ''[[Series/StarTrekTheNextGeneration Next Generation]]'' episode, an away team was also turned into children in a transporter accident.
* In an episode of ''Series/StargateSG1'', O'Neill discovers a planet where people age rapidly during the night and becomes entwined in the AppliedPhlebotinum that causes this. This is a semi-subversion, as Jack's hair grows very long as it goes gray, and after being cured Jack does NOT magically revert; he is told his still-actually-young cells will repair the ravages of fake age, but it will take a few weeks.
* ''Series/BabylonFive'' had someone caught in a temporal anomaly die of old age, even though his ship didn't have enough supplies for him to live that long. And then there was the affliction Sinclair had in the two-parter "War Without End"...
* In the episode "The Pisces" of ''Series/TheStarLost'', the crew of a scout starship discover that [[HollywoodScience relativistic]] TimeDilation has NoOntologicalInertia, so that once they slowed down they started rapidly aging to their "real" ages.

[[AC:WesternAnimation]]
* An episode of ''WesternAnimation/ChipAndDaleRescueRangers'' features recurring villaing Professor Nimnul [[CutLexLuthorACheck trying to make an honest living]]. He had invented an aging ray, and tried to demonstrate it by turning a huge bottle of milk to cheese. Not that cheese works that way, and the convention hall full of the dairy industry should've mentioned that ... and the ray does work to age things. Notably the two cops and the police car, as well as one of the Rangers.

! '''Other'''

[[AC:{{Anime}} and {{Manga}}]]
* In ''Manga/RanmaOneHalf'', victims of [[BattleAura ki]]-vampire Hinako Ninomiya's [[LifeEnergy Life]] EnergyAbsorption attacks don't age, but ''wither'', to the point where they can be rolled up like used toilet paper and even flutter in the wind. She, on the other hand, spontaneously gains enough mass to grow from her [[TokenMiniMoe eight year-old]]-looking body to her real [[HelloNurse late twenties]] appearance, [[FanWank apparently implying]] that all the [[BattleAura ki]] she absorbed was somehow transformed into biomass. Then the reverse happens when she [[KiAttacks expels the accumulated ki]] and she shrinks back down into her child form. Even her hair reverts to its original length.
* In ''Anime/MagicalGirlLyricalNanohaAs'', The Wolkenritter can steal people's magical power to fill [[ArtifactOfDoom The Book Of Darkness]].
* Isumi of ''Manga/HayateTheCombatButler'' is able to use the blood of someone (who Hayate fits the description of perfectly) to restore her powers in one arc.

[[AC:ComicBooks]]
* Comic book characters may, depending on the story, "lose their powers" even if their "power" is that they have wings, a tail, etc., as if "power" is a substance and the wings, which are physical structures, only exist if the substance is present. (See also PowersAsPrograms.)
** Averted in ''Franchise/{{Justice League|of America}}'', when a few 'Power Disruptors' are stated by WordOfGod to simply be neural disruptors that prevent then from using their natural abilities. Hawkgirl gets shot by one and retains her wings.
** In one particularly absurd example from ''SuperFriends'', a power nullifier caused Batman and Robins' ''utility belts'' to disappear.
** Played straight and then averted to a hilarious degree on the 90s ''WesternAnimation/{{X-Men}}'' cartoon. While in the Savage Land, all the mutants temporarily lost their powers. For some reason this enabled Professor Xavier to walk although his inability to walk is related to a spinal injury and has nothing to do with his powers. When villains inevitably arrived, {{ComicBook/Wolverine}} announced "I've got news for ya, bub! There's nuthin' mutant about these!" and released his adamantium claws. However, without his healing factor he nearly passes out from the pain of ''grievously injuring his hands''.
*** {{Lampshade|Hanging}}d later by Mr. Sinister: "I hadn't realised a side-effect would be your renewed ability to walk. I do hope you enjoyed it."
*** Wolverine also lampshaded this after falling off a cliff: "I could really use some mutant healing power right about now."
** Averted, optionally, in the ''TabletopGame/MutantsAndMasterminds'' superhero RPG, where superpowers can be deemed Innate, not powers at all, and thus immune to effects that drain powers.
*** Poor word choice, as the power 'Drain' specifically doesn't care if a trait is innate or not. If you have a strength Drain, you lose that innate Super-Strength too. What innate protects you from is things that target 'powers', such as Neutralize or Nullify. So if your PhysicalGod gets hit with a Neutralize, maybe he loses his lightning blasts and what-have-you, but the strength that lets him juggle small mountains? That's just the natural physical capabilities of his race, therefor is 'innate' and not technically a power, thus it is not affected.
** The Fifth Edition HeroSystem RPG introduced the advantage "Inherent", which has the same effect.
** Also happened in the ''VideoGame/CityOfHeroes'' comic-book tie-in: The villains figured out a way to negate superpowers across the entire city. This lead to a great many FridgeLogic moments, as it even affected people whose 'powers' were magic, technological or the result of physical changes, but not those who had {{Charles Atlas Superpower}}s.
** There are also numerous cases of Comicbook/{{Superman}}'s powers being transferred to someone else (including normal humans), despite the fact that his powers are a product of his Kryptonian biology.
*** In {{the Silver Age|OfComicBooks}} and [[UsefulNotes/TheBronzeAgeOfComicBooks Bronze Age]] it was a general property of anything whatsoever from Krypton, including dogs, monkeys, and inanimate objects like his costume. This was completely separate from the structure of any specific item, so transferring it is more plausible.
**** So they were transferring Krytonianness?
* The character Rogue from ''Comicbook/{{X-Men}}'' drains other mutants' powers and anyone's life force.
** Treating their physical forms very inconsistently in the process. She's been depicted as assuming part of Nightcrawler's inhuman appearance, for instance, but not Angel's wings; on one occasion she absorbed enough of Mr. Sinister's powers and personality that she effectively became him--but didn't turn chalk white, which one would assume to be simpler than growing fur.
** In ''WesternAnimation/XMenEvolution'', Rogue drains powers and life energy, but not physical traits. For example, when she touches Cyclops, she absorbs his eye beams, but not his PowerIncontinence, since that is an effect of physical trauma and not an innate part of his power.
*** There was one inconsistency regarding physical trait draining - once Rogue touched Sabertooth, she grew fur and abnormally big fangs. Reason for it? [[RuleOfFunny Making a joke about leg shaving, apparently]].

[[AC:{{Film}}]]
* ''Film/XMenTheLastStand'':
** When Beast approaches Leech, his powers are drained. Apparently his powers include "being hairy", because his hair withdrew into his body as he got close, and immediately grew back when he stepped away.
** Same happens to Mystique when she gets her shot of AppliedPhlebotinum, she loses her shapeshifting ability and looks like a normal human again. A bare naked [[strike:normal human]] ''[[FanService Rebecca Romijn]]'' at that. [[note]]The second example explains the first based on the events of ''Film/XMenFirstClass'', where it's shown that Hank's hairy appearance is originally the backfired result of an attempt to use Mystique's genes to make himself appear totally human (his mutation had only previously affected his appearance in regards to his weirdly large feet).[[/note]]
* In ''Film/SpaceJam'', the villains suck the basketball talents from five NBA players and use them themselves in an attempt to crush the Looney Tunes.
* In ''WesternAnimation/PenguinsOfMadagascar'', without any synthetic antidote for the Medusa Serum, Private uses himself instead, allowing the machine to drain cuteness from him to transfer it back to the other penguins.

[[AC:{{Literature}}]]
* The ''Literature/SimeGen'' series by Jacqueline Lichtenberg is pretty much built on this trope. "Simes" (consumers) must have "Selyn" (LifeEnergy) to live. They can get this from "Gens" (generators). Simes are mutated humans, with additional senses and tentacles added to the arms. Gens are apparently normal humans. Simes must have a 'transfer' of life-energy from a Gen once a month or die -- additional transfers can power special feats. At the beginning of the series transfer always kills the Gen, and Simes do not regard Gens as people, although Simes and Gens are inter-fertile and two Simes can have a gen child and vice-versa. During the series Simes learn how to have safe transfer and to regard Gens as people.
* A particularly egregious example can be found in Michael Crichton's sci-fi novel ''Literature/{{Prey}}'', when the main character uses an electromagnet to force parasitic nanobots out of his wife's body for about thirty-second intervals (then they swarm right back in). During that half-minute, he describes her as becoming withered and old-looking without the nanites and more normal as soon as they flood back into her.
** Probably not an actual example, as this troper recalls pretty clearly that the woman actually was starved and abused, but the nanites were essentially acting as a layer of disguise, which the magnet pulled off of her.

[[AC:{{Live-Action TV}}]]
* In an episode of ''Series/TheAdventuresOfSuperman'' (and in the comic it was originally based on), the villain Parasite was able to drain life force from his opponents. [[spoiler:But when he tried to drain Superman's power, that overloaded him, leading to the villain's demise. That ending suggests that too much of a good thing is bad, also poetic justice for hubris.]]
* Glory of ''Series/BuffyTheVampireSlayer'', who drains sanity. Described as the mystical energies that hold ones mind together the loss of them leaves the victim in a BlackBugRoom. Glory herself is a Chaos God [[SealedInsideAPersonShapedCan sealed inside a mortal man]] not capable of handling our limited perception that has to periodically drain others to save herself from such a state.
* The ''FridayThe13thTheSeries'' episode "Vanity's Mirror" had a woman with a special compact mirror. If the mirror reflects light on a victim, he or she will die and the person who wields the compact becomes more beautiful.
* Both ''Series/LoisAndClark'' and ''Series/{{Smallville}}'' employed this trope. In both cases {{lightning|CanDoAnything}} can copy Clark's powers to someone else (in ''Smallville'', the local GreenRocks also have to be involved) and both shows have had Clark's powers fully transferred into someone else with him losing them (in ''Series/LoisAndClark'' it actually got passed around from Clark to Lois to Lucille back to Clark.) Both shows have also had episodes featuring youth draining abilities or devices.
* Something like this occurs with the Weeping Angels of ''Series/DoctorWho''. They send you back in time to live out your life in the past, then feed on the years you "might have had". The Doctor says this isn't a terrible way to go and calls them "The only psychopaths in the universe who kill you nicely." That is, until [[Recap/DoctorWhoS33E5TheAngelsTakeManhattan "The Angels Take Manhattan"]], where they figure out they can make a "battery farm" of humans by sending them back repeatedly and feeding on them again and again until they age and die.
* In ''Series/{{Torchwood}}'', [[BigRedDevil Abaddon]] consumes the LifeEnergy of everyone in his shadow, which gives him a deadly PhlebotinumOverdose when the [[ResurrectiveImmortality immortal]] [[spoiler:Captain Jack Harkness]] steps up.

[[AC:TabletopGames]]
* In ''TabletopGame/UnknownArmies'', one of the perks of being a higher level Avatar of the Merchant is to allow them to facilitate the exchange of intangible qualities. They can buy your good fortune, sell your youth, or trade histories. The only rule is that the exchange must be must be mutually agreed upon.

[[AC:VideoGames]]
* In ''{{Banjo-Kazooie}}'', ugly witch Gruntilda plans to transfer the protagonist's sister's ''beauty'' to herself through a machine. You get to see the result on the Game Over screen...
** In the sequel, Gruntilda has become a zombie and plans to restore herself by draining the life force out of things. [[spoiler:The ray also goes in reverse in order to revive characters who had been killed earlier.]]
* In ''{{Creatures}}'', {{life|Energy}} and wounded are chemicals. You can't actually transfer them between creatures, but you can inject them. You can also genetically engineer them to make life out of oxygen, or, for that matter, make it out of wounded.
* The Sadhus of ''VideoGame/TreeOfSavior'' can use Send Prana to temporarily donate a portion of their Intelligence stat to an ally.

* Vriska Serket from ''Webcomic/{{Homestuck}}'' can steal {{luck|Stat}}, which apparently causes catastrophic misfortune to ''immediately'' befall her victims.

* A major plot-point of ''Webcomic/TheDragonDoctors'' is that everything living has a whole variety of essences within them; not just LifeEnergy but things which determine all characteristics. The first chapter involves a cursed valley that causes everyone who goes there to be turned permanently into a woman; it turns out there was an artifact that sucked up "masculine essence" from everything around it to promote plant growth. The reason this turns men into women is that the essence of both genders exist within people and getting rid of all the manliness tips the balance. Goro the muscular war surgeon gets all of all his strength (and masculinity) sucked out of him when he tries to physically attack the artifact, winding up a skinny, sickly woman who needs a strength essence infusion at a hospital later (it's treated like an organ transplant). Most of this is justified as magic working with "concepts" rather than raw physics.

* One episode of ''StaticShock'' featured a power draining villain, which captured several members of the Rogue gallery to drain them for his benefit; including Talon, a villain with wings. When she was recovering from the drain, it showed her feathers growing, as if the draining caused them to shrink.
** Another episode saw a large number of Bang Babies kidnapped and drained so [[spoiler:Edwin Alva could restore his son from statue-form, which was the result of an earlier SuperpowerMeltdown from trying to combine all the potential powers of the Bang Baby Gas.]]
* The ''WesternAnimation/TinyToonAdventures'' episode "Washingtoon" had the A.A.F.C. (standing for Adults Against Funny Cartoons, of course) chairperson, the main villain of the episode, using a machine to drain cartoon characters of their "tooniness." Buster's tooniness is too strong for the machine, breaking it and restoring everyone's tooniness ([[spoiler:although [[FreakyFridayFlip not all of them to their proper bodies]]]]), including [[spoiler:the A.A.F.C. chairperson's tooniness, which had been lost many years ago]], and saving Acme Acres.
* The season 4 finale of ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' saw Tirek draining magic from unicorn ponies, which would seem to make enough sense, although he also steals ''flight'' from pegasus ponies, leaving them unable to fly (but with their wings still intact) and he steals physical strength from earth ponies. Interestingly, the ponies' cutie marks also vanish when these things are removed, even if their talent wasn't related to magic, flying, or strength.
