* Unfortunate humans captured by demons in ''VideoGame/ShinMegamiTensei'' games can look forward to being used as a power source as their eventual fate. The Mantra facilities and the Nightmare System in ''Nocturne'' and the Ashura-Kai Red Pill creation process are good examples of this, some of them crossing with PeopleFarms.

* ''[[https://archiveofourown.org/works/27853170/chapters/68194306 Pulse and Void]]'' subjects poor Present Mic to this. The mastermind, Pulse, has Mic tortured and dosed with Trigger, a quirk enhancer, to draw energy from Mic’s screams. He also has a cohort with a teleport quirk that draws energy from the poor guy. Luckily she has a beef with Pulse and feeds Aizawa location information. Mic’s body is pushed into metabolic overdrive and gives him a NothingButSkinAndBones look as though he was starved several weeks rather than just one.

* The monster [[http://www.bogleech.com/mortasheen/abcoulix.htm Abcoulix]] from ''WebOriginal/{{Mortasheen}}'' was designed for exactly this purpose, though it also works very well at dispensing ShockAndAwe in monster fights.

* In the Franchise/{{Pokemon}} fanfic ''FanFic/ThePowerThatsInside'', Pokemon bioenergy is used to power human civilization. An increase in the amount of Pokemon being used for this causes an uprising.
* ''Fanfic/FantasyOfUtterRidiculousness'': [[spoiler: Reimu willingly turns herself into one of these temporarily to give Megas access to her power set, and thus provide it with the means to do meaningful damage to Yuuka.]]
* ''Fanfic/TheBridge'': Enjin tries to absorb Aria Blaze and the human form of Monster X into its crystalline core in a bid to get enough power to return to its true form. [[spoiler: Aria manages to give her necklace to X and shove him out of the way so Enjin would only get half of her magic and he'd get the other half, causing them both to return to their kaiju forms and duke it out. Aria fights to remain conscious inside Enjin and launches an internal attack to wound it and give the weaker X a power boost. Monster X finally manages to destroy Enjin by damaging its core and safely yanking the part of it containing Aria out, but he barely manages to resuscitate her after.]]

* The badniks of early ''VideoGame/SonicTheHedgehog'' games were powered by little animals, making it Sonic's mission to destroy them, freeing his friends inside. This played a large ([[HeroicSacrifice and tragic]]) part in E-102 Gamma's story in ''VideoGame/SonicAdventure''.

* Masters in ''VisualNovel/FateStayNight'' act as batteries for their Servants, empowering their abilities and allowing them to maintain a physical form. This is a dangerous prospect for some Masters, as a reckless Servant can use so much prana that it kills their Master [[spoiler:as with [[LightNovel/FateZero Berserker and Kariya in the Fourth War]]]].

* In the ''Series/BuffyTheVampireSlayer'' episode "[[Recap/BuffyTheVampireSlayerS4E18WhereTheWildThingsAre Where the Wold Things Are]]", Buffy and Riley are living batteries in a frat house via nonstop sex.

* In ''Literature/{{Coda}}'', Conduits power the city via energy extraction. [[spoiler: They also power President Z and the Board.]]

* In the fourth season of ''Series/BuffyTheVampireSlayer'', there is an episode where Buffy and Riley are living batteries in a frat house via nonstop sex.
* ''Series/DoctorWho'': In "[[Recap/DoctorWho2005CSTheChristmasInvasion The Christmas Invasion]]'', the Doctor says that the "pilot fish" could run their batteries off his excess regeneration energy for "a couple of years".

* In the ''Series/StarTrekVoyager'' episode "Equinox", the USS ''Equinox'', like ''Voyager'', had found herself trapped in the Delta Quadrant. Her crew has discovered a faster way to get home by torturing the alien of the week. Janeway is not pleased. The rest of the victims' race [[RoaringRampageOfRevenge are even less pleased]].
* On ''Series/StarTrekEnterprise'', the [[LizardFolk Xindi-Reptilians]] use regenerating worms to power their energy rifles.

* ''LightNovel/AscendanceOfABookworm'': All of the {{Magitek}} is powered by {{Mana}}. Plants will also grow much better on mana-rich land, which results in farmland needing to be topped up on a regular basis. The most powerful members of the SupernaturalElite have willingly powering the devices that protect the population among their duties. Those born with so little mana that they are practically a MuggleBornOfMages are forbidden from attending WizardingSchool, LockedAwayInAMonastery to an extent and only allowed to use what little they have towards topping up farmland. As mana remains a limited resource, members of the SupernaturalElite that did something bad enough to be imprisoned are often used as batteries, as well. Because of several elements of the setting, MageBornOfMuggles commoner children are often enslaved to be used as mana sources.

* ''WesternAnimation/HamsterAndGretel: [[WhatKindOfLamePowerIsHeartAnyway La]] [[LargeHam Cebo]][[BlessedWithSuck llaaaa!]] uses Gretel this way to power a device that will amplify her ability to speak to onions. When Gretel protests her actions, she responds by saying that batteries don't talk.

* The best devices of ''Literature/TheTommyknockers'' were CastFromHitPoints.

* The entire Inkling and Octarian civilizations in ''VideoGame/{{Splatoon}}'' and ''VideoGame/{{Splatoon 2}}'' derive their electrical power from Zapfishes, electrical catfish that are a natural species in their world. In turn, the Great Zapfish is the biggest and central source of power. The Zapfishes don't seem to be sentient, and it's unknown if they mind being placed in chambers and harnessed for their electricity or not (but the Great Zapfish willingly secures itself on Inkopolis Tower). However, major conflicts between Inklings and Octarians happen due to there being fewer Zapfishes than can sustain both civilizations.

* In ''ComicBook/ElseworldsFinestSupergirlAndBatgirl'', ComicBook/LexLuthor is the one to find [[spoiler:Franchise/{{Superman}}'s rocket]], and he turns [[spoiler:the baby]] into a battery for clean energy machines.
* One of the villains of the week in ComicBook/EMan was a millionaire who was having homeless people kidnapped to use as power sources to run his mansion off of, as it was set during the height of the energy crisis back in the 70s.

* In ''ComicBook/SupermanAndTheLegionOfSuperHeroes'', villain Earth-Man captures Sunboy and turns him into a battery for a device that transforms the Earth's sun into a red star.

* ''ComicBook/UncannyXMen'': When the group first discovered the island of Genosha, they discovered that mutants had been enslaved to increase the quality of life for the human citizens. One mutant was used as a living power source for the monorail-like mass transit vehicle that he piloted.
** In another series called ''X-Treme X-Men'' about a multiverse traveling team of alternate X-Men (No [[ComicBook/{{Exiles}} not that one]]) had an arc where they traveled to an Earth where Magneto cracked the crust and destroyed the magnetic field out of spite. Thinking quickly, all the world's smartest scientists devised a machine capable of drawing upon mutant energy to hold the planet together. They supply it with mutants from parallel realities and have been draining them dry countless times, with their personal effects kept in storage in an [[DoesThisRemindYouOfAnything eerie parallel]].

* ''Manga/BlackBird'' has this, with a twist. The living battery (the heroine) isn't harmed by having her energy used. She just gives it off like a fire gives off heat. Though the ''other'' things that she can provide aren't nearly as non-invasive to harvest...

* In ''WesternAnimation/{{Ben 10}}'', Max met his future wife Verdona when a group of aliens meant to use her (an EnergyBeing) as a power source, which would be painful and eventually kill her.
