History Main / MindHive

* Ermac from the ''Franchise/MortalKombat'' series was a single being created via the combination of a legion of souls by Shao Khan and tends to speak as "we" to represent this fact. ''VideoGame/MortalKombat9'' reveals that [[spoiler:Edenia's former king Jerrod]] is one of the souls within Ermac. ''VideoGame/MortalKombatX'', which follows a TimeSkip after the previous game, implies that [[spoiler:Shao Khan's soul]] has joined them.

* ''Literature/XanaduStoryverse'': A group of dragon dancers, implied to have been named Ben, John, Phil and Ray, are turned into a single Chinese dragon named Behjopiray. The new creature's mind is presented as an amalgam of the four people who were turned into it, and its internal monologue is a set of four distinct commentaries with slightly different personalities -- most are largely subsumed into the new draconic persona, but the last one retains more of its human memories.
* Hohass "Runt" Ekwesh from the ''Literature/XWingSeries'' is this. He has many minds and they're all different. There's the pilot mind, the pirate mind, the careful mind, the student mind -- in fact, his entire race is made up of creatures with a different mind for each task.

* ''WebVideo/TwitchPlaysPokemon'': This is pretty much exactly how the stream works. It's essentially a game of ''Franchise/{{Pokemon}}'' where the player character is controlled via chat by... anyone. The end result is that hundreds to thousands of people are ''constantly'' controlling the character. Imagine two or three people fighting over a video-game controller, multiplied by several thousand. Add to that about a 20+ second delay between input and action [[HilarityEnsues which the majority of people don't even realize is there.]]

As a HiveMind is one mind, many bodies, a Mind Hive is the opposite - many minds, one body.

* In ''Manga/FullmetalAlchemist'', [[spoiler:Hohenheim]] is this, due to being a living Philosopher's Stone. He's revealed to have reached an accord with each of the tens of thousands of souls sharing his body, though he's the dominant one in control.

* At the end ''AudioPlay/SaintBeast: Kouin Jojishi Tenshi Tan'', there is a monster made up of the angry spirits of purged angels, sharing one giant body of miasma. A similar case occurs earlier with the dead of the lake town.
* The [[BodyHorror AIM Fetus]] from the Level Upper arc of ''Manga/ACertainScientificRailgun'' is a Mind Hive born from HiveMind of the users/victims of Level Upper. It reflects their mind, all of whom lament their lot in life as weak espers. When the giant flying baby-thing is defeated, the victims of Level Upper wake up from their coma.
* ''Franchise/{{Digimon}}'':
** Apocalymon from ''Anime/DigimonAdventure'' is a single life-form created from the collective data of all Digimon who died in failed attempts to evolve.
** ''Anime/DigimonFrontier'' has [[AllYourPowersCombined Susanoomon]], which acts as this for both the heroes themselves and the Ten Legendary Warriors.
* [[spoiler: Kirito Kamui]] from ''Anime/PsychoPass'' turned out to be this kind of entity, and as a collective he became immune to the Sibyl System, which analyses [[{{Thoughtcrime}} Crime]] [[PrecrimeArrest Coefficients]] on an individual basis.
* ''Literature/FateApocrypha'' has Jack the Ripper, a HumanoidAbomination that takes the shape of a young girl, but in reality is the aggregate of the hate, fear and pain of thousands of abandoned and abused children in VictorianLondon.
* In ''Anime/DragonBallZ'', Imperfect Cell evokes this trope to try and trick Android 18 into letting herself be absorbed, by mimicking Android 17's voice and asking her to "join him". 18 very briefly swayed, but very quickly sees through the trick.
* In ''Franchise/MyHeroAcademia'', Izuku Midorya gains a version of this when he gains the ability to communicate with the previous One for All users in dreams and trance states. At first he can’t talk to them but gains that ability as well. Two users reject him at first but relent at the urging of the first user. It causes trouble when Midoriya manifests Blackwhip the first time. Another student with a brainwashing Quirk tries to brainwash Midoriya to help him regain control and it fails because his Quirk can only brainwash one person at a time while Midoriya had multiple entities in him.
* ''Literature/SoImASpiderSoWhat'': Protagonist Kumoko eventually gains the skill "Parallel Minds", which essentially creates new "brains" inside her (symbolized by whole new versions of herself), which are capable of separate thought and are tasked with taking care of different things during fights (for example, there is a Body Brain responsible for her movements and attacks, letting the original brain only act in processing information and strategizing, and later a brain whose only responsibility is to figure out how magic works and cast it during fights is added). Each new brain is added to her SplitPersonalityTeam and they work together to make decisions outside of fights, like which skills she should invest on.

** The cyborg ComicBook/DeathsHeadII has assimilated the minds of 106 targets from across time and space. Most of them are suppressed, with Death's Head drawing on their skills but not overtly influenced by their personality. But there have been exceptions - mostly notable the ''original'' ComicBook/DeathsHead, but also [[ComicBook/{{Battletide}} Bezial]] (who refused to cooperate and later stole a new body of his own) and Czorn Yson (who later built a new body and became ComicBook/DieCut).
** ComicBook/{{Deadpool}} has been known to house other minds within his own due to unusual circumstances. Agent Preston gets put into this position until they can put her mind into an LMD, while [[spoiler:Madcap rode along in Deadpool's head for a while after merging with him, becoming the "second voice" in the Daniel Way run until they were split up again in Deadpool Annual #1]].

** [[ComicBook/TheIncredibleHulk Bruce Banner]] has multiple personalities. Apart from the ones we've seen, they're all dormant, depicted in his mind as frozen in ice as a kind of stasis. When the ice breaks they start fighting for control.
* In the ''ComicBook/{{Supergirl}}'' storyline ''[[ComicBook/Supergirl2011 Be Careful What You Wish For]]'', the titular heroine comes upon the Inoxians, an alien race who are a collective consciousness.

* The ''ComicBook/MegaManArchieComics's'' version of ''VideoGame/MegaMan3'''s Doc Robot is one, containing the personality chips of all eight ''VideoGame/MegaMan2'' robot masters.
* In ''ComicBook/{{BPRD}}'', the Oannes Society planned to save humanity from the Ogdru Jahad by preserving the souls of millions of people inside the bodies of a half dozen genetically engineered giants (with the unfortunate side-effect that everybody else would have wound up getting bumped off ahead of schedule).
* Winged Victory from ''ComicBook/AstroCity'' is backed by the Council of Nike, a worldwide psychic network of thousands of women. Their unified goal is to help women everywhere, with Winged Victory being a vessel for their collective power. She becomes considerably weakened when they question her devotion to the cause.
* During the Eighth Doctor's tenure in ''Magazine/DoctorWhoMagazine'', he fought against one of these. Turns out his companion Grace Holloway saved some of the saliva the Master spat at her during TheMovie, and had begun researching it in hopes of introducing regenerative capabilities on humans. Unfortunately, at that point in time the Master was actually possessing an alien creature, and only his strong will kept his body's urges and the influence of the other mind he consumed in line. The arrogant scientist who gained control of the project lacked the Master's will and experience with mind control, so he rapidly decayed into a lumbering mass of protoplasm, tormented by the dozens of minds he'd consumed, until the Doctor mercifully blew him up.

* ''Fanfic/AnimorphsTheReckoning'': Andalites, being a naturally telepathic species, tend to GoMadFromTheIsolation when stranded on a planet without others of their kind. To remedy this, Aximili voluntarily hosts [[PuppeteerParasite Temrash, a Yeerk]], in order to provide the constant social stimulation he requires. In addition to the LivingMemory of Elfangor that Ax mentally carries, Temrash itself brings remnants of its previous host - Jake's brother, Tom, [[GotMeDoingIt and all his catchphrases, personality quirks, and human mannerisms]]. Marco points out how off-putting the resulting amalgam behaves.

* ''WebVideo/DragonBallZAbridged'': Piccolo becomes one of these after fusing with Nail. Unlike in the source material, Nail retains his individuality inside Piccolo's mind after the fuse and can converse with/constantly annoy him freely. [[spoiler:Later, Piccolo also fuses with Kami, and his head starts getting even more busy.]]

* ''[[https://archiveofourown.org/works/27736435 Zero Context: Taking Out the Trash]]'': Callista is shown to deal with this. [[Anime/PowerpuffGirlsZ Kaoru Matsubara]] resides in her head and can switch places with Callista at any time, swapping both bodies and minds. Her subconscious is also home to the Copycats, physical representations of the darker and lighter aspects of her personality who are constantly squabbling with each other.

* In ''Film/TheExorcist'', the demon Pazuzu appears to be one, containing the souls of the damned deceased. ("Your mother's in here with us, Karras.")[[note]]Not likely, since Karras' mother was devout and proud that her son was a priest.[[/note]] [[UnreliableExpositor Maybe]]. [[MaybeMagicMaybeMundane Even less certain in the book]]. Even with all the proof he's seen, Karras still thinks of it in terms of "manifesting personalities," until Fr. Merrin, a world-renowned exorcist, dismisses this with a flat "There is only one." And since he's evicted Pazuzu before, you can take what he says to the bank.

%%* Shades in ''Literature/InheritanceCycle''.
* In Ekaterina Sedia's ''Literature/TheAlchemyOfStone'', the soul-smoker is this after a lifetime of absorbing ghosts.
* In ''Literature/{{Animorphs}},'' [[SufficientlyAdvancedAlien the Ellimist]] has a pattern of switching between "I" and "we", so characters are unsure of how many Ellimists there are. The prequel book reveals that this trope is actually in play -- before getting godlike powers, the Ellimist was an alien refugee captured by "Father", a massive sea-creature that killed countless people (including the few other members of the Ellmist's species) and absorbed their minds. The Ellimist eventually defeated Father and [[ManySpiritsInsideOfOne absorbed the minds into himself]].

* In Glen Cook's ''Literature/TheBlackCompany'' novels, [[AxCrazy Soulcatcher]] (a powerful spellslinger whose primary talent is ExactlyWhatItSaysOnTheTin), might well be the epitome of this trope.
* In Gene Wolfe's ''Literature/BookOfTheNewSun'', there are several ways this can happen. [[spoiler:Alzabos are animals that can [[EatBrainForMemories absorb the memories and personalities of the dead people they eat]]. Corpse-eater cults use an alzabo derived drug to do the same. The Autarches do the same by eating the brain of their predecessor while he or she is still alive.]]
* ''Literature/TheChaosCycle:'' Abaddon, the evil spirit and antagonist of the first book The Hollow Gods, [[spoiler:is actually a collection of minds in one form. Since ancient times, Abaddon has constantly made the same evil mistakes over and over again so many times through all of his reincarnations that he's become a combined entity of sorts with the mind of each of his past lives exerting some control but led by his original incarnation, known as "The First" aka the God of creation Velizar.]]

* Frank Herbert's ''Franchise/{{Dune}}'' series. Abominations are people who experience [[GeneticMemory Bene Gesserit memory sharing]] before birth. As a result, they are subject to being taken over by the personalities of their genetic ancestors. This can lead to some interesting situations:

* The protagonists of ''Black Star Rising'' by Creator/FrederikPohl include a scientist known as Manyface, who once nearly died from brain damage that was treated by replacing the lost sections with pieces from the brain of a dead boy. When asked if he could remember his name, he gave it, then gave the dead boy's name a second later. The two realized that their joined knowledge was a great aid to the scientist's research, and by the start of the story they've collected so many brains they've had to undergo experimental skull-enlargement surgery to fit them all in.

* [[AmbiguousGender Mallory]] in the ''Literature/JacobsLadderTrilogy'' has "a head so full of dead people I suspect whoever I started off as should probably be counted as one of them". Mallory is a necromancer, which in this setting means [[spoiler:collecting the data of now dead people to prevent their knowledge, skills and whatever else of themselves they had saved before death from being lost, and being able to use that information, all the while getting all the individual people to be nice to each other]].

** During ''Looming Shadow'', Basilard looks into the surface of [=BloodDrinker=]'s blade and sees countless Bladi chiefs staring back at him, the souls of the sword's previous wielders.
* Author Keiichiro Hirano explores a similar idea -- that of "dividuals" -- in his 2009 near-future science-fiction/political thriller ''Dawn'' and his latest work ''Fill the Void''. Acting as an alternative to "individualism" -- that is, the idea that the different masks we wear in everyday life in response to the situations and people around us are all simply parts of the same core "personality" or "individual" -- "dividualism" posits that the different personalities we seem to have are just that: distinct entities ("dividuals") generated naturally by the interaction between a person and his or her environment or conversational partners, all of which exist simultaneously within that person and emerge at the appropriate time. In the works (particularly ''Dawn''), the implications of whether to accept or reject this model of "personhood" on the level of society are discussed at length, in the context of both intimate personal relationships and a major battle of political ideology.

* [[MagnificentBastard Quick Ben]] from the ''Literature/MalazanBookOfTheFallen'' is [[Literature/TheBlackCompany Soulcatcher's]] (see above) understudy in this (and possibly inspired by the very same). He's got twelve souls rattling around in his brain and has a habit of talking to himself in different voices when no one's looking, but he claims to have reached some kind of consensus with them.
* Lord Mark Vorkosigan in ''Literature/MirrorDance'' develops four alternative personalities he calls his "black gang".
* The basis of many [[SufficientlyAdvancedAliens "super-intelligences"]] in the ''Literature/PerryRhodan'' universe, who tend to form when entire species AscendToAHigherPlaneOfExistence under the right conditions. Also seen in the so-called "concepts" briefly created by IT (the mostly benevolent super-intelligence claiming among others the Milky Way galaxy as its domain, not the It cited just above) when the latter suffered from a spontaneous case of MySkullRunnethOver after absorbing virtually every human being on Earth at the time to save them from a rival. Concepts consisted of several minds in the body of one member of the group; the most iconic case was Kershyll Vanne, a highly trained agent who found himself sharing his body with the minds of six specialists with different areas of expertise. He ended up playing a key part in freeing the then-occupied galaxy.
* In ''Literature/{{Remnants}},'' Tate's "power" is that she turns into a sort of [[TheBerserker Beserker]] with a huge mouth who tries to eat anything around her. When she gets ADayInTheLimelight, she winds up eating the villains and has their minds living in her head. [[spoiler:Yago and Amelia wind up having a HeelFaceTurn and stay for the rest of her life.]]
* Hohass "Runt" Ekwesh from the ''Literature/XWingSeries'' is this. He has many minds and they're all different. There's the pilot mind, the pirate mind, the careful mind, the student mind -- in fact, his entire race is made up of creatures with a different mind for each task.
* One tie-in novel for ''Series/StarTrekTheOriginalSeries'' has the ''Enterprise'' make contact with a Vulcanoid race capable of housing multiple minds in one body (basically, the ''katra'' transfer from ''Film/StarTrekIITheWrathOfKhan'' taken to the next level). One representative from this race has 413 minds inside her, which Kirk notes is almost the crew complement of a ''Constitution''-class starship.

* Legion in ''Literature/TheDeathMageWhoDoesntWantAFourthTime'' is a flesh slime-like creature hosting souls of eleven individuals (both male & female) & one parasite life form. It takes the form of whichever personality emerges & gradually gained the ability to temporaily seperate a personality from it's main body.
* [[YouKillItYouBoughtIt Butcher]] [[LegacyCharacter XIV]] from ''Literature/{{Worm}}'' carries the consciousnesses of every previous bearer of the Butcher mantle.

* ''Series/{{Crusade}}'' had one of these as a MonsterOfTheWeek. It began to spread parts of itself amongst the crew of the Excalibur, [[MindVirus turning each crewmember into a platform for one of its personalities]].

** Colony Sarff, Davros' servant from [[Recap/DoctorWhoS35E1TheMagiciansApprentice "The Magician's Apprentice"]]/[[Recap/DoctorWhoS35E2TheWitchsFamiliar "The Witch's Familiar"]], is a mass of sentient snakes which can collect together to take on a humanoid form. It claims to be a democracy.

** {{Downplayed|Trope}} with joined Trill as depicted in ''Series/StarTrekDeepSpaceNine''. A Trill who plays host to a symbiont will have all the memories and experiences of previous hosts, as well as elements of their personalities, but (if properly trained) won't be consumed by them; the current host instead retains his/her individuality.

* ''TabletopGame/DungeonsAndDragons''
** 3rd Edition introduced the playable synad race in the ''Complete Psionic'' handbook. Each synad has three fully independent minds fused into a functional whole: an "overmind" that controls the synad's actions most of the time, and two "subminds," a "collective" mind that can tap into the synad's [[GhostMemory racial memory]] and an "oracle" mind that can offer CombatClairvoyance once per day. Besides ensuring that a synad is never alone and can always look at problems from multiple viewpoints, their threefold minds let them more easily resist mental attacks, or "multitask" by spending a power point to have a submind perform a purely mental action as a free action. This quirk affects the synads' appearance - in normal light they can pass for tall, hairless humans, but in dim lighting, and if a synad has expended all their daily power points, two ghostly visages representing their subminds become visible around a synad's physical head.

* Ermac from the ''Franchise/MortalKombat'' series was a single being created via the combination of a legion of souls by Shao Khan and tends to speak as "we" to represent this fact. ''Videogame/MortalKombat9'' reveals that [[spoiler:Edenia's former king Jerrod]] is one of the souls within Ermac. ''Videogame/MortalKombatX'', which follows a TimeSkip after the previous game, implies that [[spoiler:Shao Khan's soul]] has joined them.
* Archons and Dark Archons from ''Franchise/StarCraft'' are the result of the merging of 2 High Templars or Dark Templars (or in Starcraft 2, one of each). Ulrezaj is an extreme case, the merging of 7 Dark Templars. Also, in the ''Dark Templar Saga'' novels, Jake (a human) and Zamara (a Protoss "preserver") merge; however, her presence in his mind causes a brain tumor.
* The Many in ''VideoGame/SystemShock2''. In contrast to self-centered megalomaniac Shodan, who speaks in the {{voice of the legion}}, The Many alternate between separate and distinct voices. Humans assimilated by it begin slipping into the voice, though.
* The Beast in ''VideoGame/HomeworldCataclysm'' is both. It converts spaceships and control them with its conciousness, but at the same time absorbs all the data it finds and uses it to form its speech pattern.
* The Valkyries of the ''VideoGame/ValkyrieProfile'' series utilize this trope. The souls of einherjar -- warriors deemed worthy enough to become part of Odin's armies -- are taken into a Valkyrie's body and dwell within her while she continues her duties in the mortal realms. As Valkyries are also responsible for helping to train einherjar in preparation for service in the afterlife, they can temporarily summon the einherjar to their side during combat.
** Alicia from ''Valkyrie Profile 2: Silmeria'' is the best example of the trope in action. She's just a human teenager, but her body is ''also'' the "can" of the Valkyrie Silmeria, who shares control of Alicia's body. Silmeria ''also'' has a large host of Einherjar residing within ''her'', and they can speak in Alicia's mind (as they do in the opening cutscenes).
* ''Franchise/KingdomHearts'': Sora. [[spoiler:There are three, maybe four, other minds in his heart at this point, and the earliest has been there since he was four.]] It comes to a head in ''[[VideoGame/KingdomHearts3DDreamDropDistance 3D]]'' when he starts to learn the truth, and the villains ask where he ends and the others begin.

*** Considering the revelations in the climax of the second game [[spoiler:on how Reapers are created, it's possible that the individual "programs" of Reapers are actually the remaining minds of the intelligent beings used to produce the Reapers.]] The geth actually [[http://youtu.be/CqtAHNQT3-w speculated correctly]] about the exact nature of the Reapers, though this was just one of many theories.

* In ''VideoGame/Portal2'', it is revealed that [=GLaDOS=] was constructed with at least one if not more [[BrainUploading uploaded human personalities]] in addition to the multiple contradictory directives and {{Restraining Bolt}}s that Aperture Science tried to install to keep it in check.
* ''Franchise/{{Pokemon}}'': Spiritomb is made up of [[Mystical108 108]] spirits combined into one rock called the Odd Keystone.
* An OriginalCharacter from the EA game ''VideoGame/MarvelNemesisRiseOfTheImperfects'' was Brigade, a SuperSoldier whose mind (and body) consisted of an entire squad killed in an explosion, and subsequently saved by Rukko, who implemented an alien neuro network to combine their minds after he used cybernetic components to merge their bodies. [[CameBackWrong It's not without its effects, however]]...

* In ''Videogame/AbyssOdyssey'', the Ghost Monk is a hooded skeletal figure that is an amalgamation of all the Chilean soldiers that have died fighting the Warlock's dreams in the Abyss. The Chilean army fights alongside him in trying to defeat the Warlock, partly because they don't want to become part of him.
* Kalista of ''VideoGame/LeagueOfLegends'' is a spectral version of this. When a wronged individual summons the Spear of Vengeance, their soul becomes part of the ever-growing amalgam of minds that is Kalista.

* ''VideoGame/FiveNightsAtFreddys'' has two of these, Ennard and Molten Freddy (although the latter is just the next stage of the former after they kicked one character out for supposedly being a 'bad leader').
** [[spoiler:Golden Freddy also seems to be one, made up of the Crying Child and The One You [[[BigBad William Afton]]] Should Not Have Killed.]]
* ''VideoGame/DragonQuestXI'': The good ending of [[spoiler:Hendrik's]] plot arc, in the post-game, sees this happen when the spirit of [[spoiler:Jasper]] willingly merges with them to help defend the Luminary and atone for past mistakes. This results in a snazzy new costume and the character sometimes speaking in the plural.

* ''VideoGame/XenobladeChronicles3'': [[spoiler: [[BigBad Z]] is the AnthropomorphicPersonification of people’s fear of change. This means that he is an amalgamation of the many fears of different people]].
* ''VideoGame/RiskOfRain2'': The Heretic is referred by she/her pronouns in flavor text, but is called "they" in their [[spoiler:ending, if the player becomes her. Since you transform into her if the player grabs all of her body parts, it's implied that she and the survivor have become one person occupying the same body.]]

* ''WebAnimation/RedVsBlue'' has an unusual example. The Meta has a collection of A.I.s in his head and continues to collect more. Since the A.I.s are all [[LiteralSplitPersonality fragments]] of an original A.I., it's a little unclear of how much of the individual personalities they -- or their human host -- retain.
* In ''WebAnimation/IfTheEmperorHadATextToSpeechDevice'', the Emperor explains that his stay on the Golden Throne has fractured his mind in so many tiny pieces that while he can conceivably know ''everything'', he doesn't know this because the part of him knowing is in the other end of the Warp.

* ''Webcomic/{{Comedity}}'': Garth. Even though most of the head-Garth represents part of his thinking process, the Muse and the Penguin are still quite independent.

* In ''Webcomic/{{Homestuck}}'', when two sentient beings are used as the ingredients of a [[SpiritAdvisor Sprite]], this may be the result. An animal and a human results in the human mind being dominant with a few personality tics, while combining two sapient ingredients results in this trope, with the two minds attempting to work as one, with varied results.
* Chairman Jack of ''Webcomic/ChairmanJackEmerge'' (The sequel to ''Webcomic/ABeginnersGuideToTheEndOfTheUniverse'') has been advanced to this point [[spoiler:by the [[RealityWarper Everyman]] after he gains full power]] so that he has an entire board of various parties in his mind who move various actions.
* [[StarfishAlien The Nobles]] in ''Webcomic/DeepRise'' are this: Each have between 10 and 20 neural centers for each individual, collectively referred to as "Congress". Also, representative of the readers' suggestions.
* ''Webcomic/StandStillStaySilent'': Giants are this in addition to being a BodyOfBodies of trolls. Beings that are the ghost equivalent to giants appear later in the story.

[[folder:Web Original]]
* ''WebVideo/CriticalRole'' has [[spoiler:Cognouza, a neighborhood of Aeor that was shunted into the Astral Sea when the gods shot the city down. The Somnovem, Cognouza's leaders, hoped to save themselves and bring their people to a realm where dreams could be reality -- but when they arrived, they landed in the middle of a psychic storm that shattered every soul in the city. Those pieces eventually reformed and merged with the city itself, [[EldritchAbomination transforming Cognouza into an eternally hungry city of flesh]], inhabited by thousands of gibbering, screaming souls begging for death, with the equally insane Somnovem at the helm.]]
* During one of WebVideo/{{Failboat}}'s livestreams, he coded a war for his live chat to play Bandana Waddle Dee alongside him in ''VideoGame/KirbyAndTheForgottenLand'', just like ''Twitch Plays Pokemon'' (see below). Chat, using TTS, interpreted this as Waddle Dee being possessed by thousands of different voices, which technically he is.
-->'''Waddle Dee:''' I cry out for salvation, for a thousand souls speak through my lips.
* In ''Website/OrionsArm'' this is [[http://www.orionsarm.com/xcms.php?r=oaeg-view-article&egart_uid=4b9f2a844034a the proposed explanation]] for how the minds of transapients work.

* ''WebVideo/TwitchPlaysPokemon'' : This is pretty much exactly how the stream works. It's essentially a game of ''Franchise/{{Pokemon}}'' where the player character is controlled via chat by... anyone. The end result is that hundreds to thousands of people are ''constantly'' controlling the character. Imagine two or three people fighting over a video-game controller, multiplied by several thousand. Add to that about a 20+ second delay between input and action [[HilarityEnsues which the majority of people don't even realize is there.]]
* [[http://www.scp-wiki.net/scp-2003 SCP-2003]] from the ''Website/SCPFoundation'' is a time travel device that the Foundation uses to see possible futures. One of them has the consciousness of ''134,000 people'' jammed into the body of a single human being, who is then confined to a cell and automatically dispensed food while the rest of humanity is wiped out.

* ''WesternAnimation/{{Amphibia}}'': In "Olivia & Yunan", it turns out the GreaterScopeVillain that [[BitchInSheepsClothing King Andrias]] has been reporting to is [[spoiler:"The Core", an amalgam of Newtopia's greatest minds who [[ImmortalitySeeker live on in death]] through [[BrainUpload uploading]] their collective consciousness into a mechanical body. Unfortunately, it decided to seek a living host, and [[GrandTheftMe it chose]] [[DemonicPossession Marcy]]]].

* ''WesternAnimation/StevenUniverse'': Fusion tends to work this way. When two or more Gems fuse with each other, an entirely new entity is created, but if the new form is unbalanced or experiences emotional turmoil, the constituents can often be heard speaking back and forth through the combined form's individual voice. It's even described as one character as being akin to a conversation, though the literal metaphor of the FusionDance may be a more apt comparison, in that the result is no longer two beings, but not quite just a whole new being; rather, fusion is an experience, the parts having to work in-synch for the whole to function. [[WordofGod According to]] [[Creator/RebeccaSugar Rebecca Sugar]], one of the [[spoiler:"permafusions", Flourite, who is composed of six different Gems,]] speaks very slowly for this sole reason. The more Gems are involved, the harder it is for all of them to be in sync so that their combined form is speaking for everyone.

** Subverted with the elder brains of the illithids, which are supposedly a gestalt consciousness of all the mind-flayers who have gone before them, absorbed into the greater whole. That's just what the elder brains tell the illithids. Absorbing illithid brains give them the fallen illithid's pychic energy and memories, but nothing of their consciousness remains.

* ''TabletopGame/DungeonsAndDragons'' 3rd Edition introduced the playable synad race in the ''Complete Psionic'' handbook. Each synad has three fully independent minds fused into a functional whole: an "overmind" that controls the synad's actions most of the time, and two "subminds," a "collective" mind that can tap into the synad's [[GhostMemory racial memory]] and an "oracle" mind that can offer CombatClairvoyance once per day.

* The Amalgam playbook from ''TabletopGame/InterstitialOurHeartsIntertwined'' lets you play as one, and even induct additional characters into the hive as you advance.
* Eldar exarchs in ''TabletopGame/Warhammer40000'' have the souls of all previous wearers of their armor bound into it. Though the mind of the wearer (usually) remains dominant, they can commune with the souls of the previous exarchs and gain their knowledge. Phoenix Lords, the oldest of the exarchs and creators of the Path of the Warrior are an exception though. Their souls are so powerful that the original personality will dominate all others, causing anybody who wears their armor to effectively become a reincarnation of the Phoenix Lord.
** Eldar Craftworlds are also this, as souls of dead Eldar are placed within the Craftworld's infinity circuit to protect them from being devoured by Slaanesh. There's an in-universe quote describing the Craftworld as "a living being, with a hundred thousand minds".

** Visser One concludes that humans as a race are this. Self-doubt and second guessing are alien concepts to Yeerks until they meet humans, and their best translation is that it is like living with your own worst traitor in your head. She also sees the advantage of this, as unlike an external traitor, the internal human one still has the survival of the human as a major interest, so the decisions humans make are wiser because the considered the possibility that they could lose. As a whole, Yeerks find humans to be very frustrating to infest, as humans tend to fight them, if only a near constant barrage of SnarkToSnarkCombat, long after the point where other hosts would have given up. The Yeerk who infested Jake states that Tom knew that it was useless, but still tried to tell him what to do and mocked him like Jake was doing. Chapman's Yeerk had to make concessions to the man because Chapman's will was such that he could overthrow control from time to time, something that other races could not do and Yeerks saw as bad form on the part of the Yeerk.

* In ''WebOriginal/OrionsArm'' this is [[http://www.orionsarm.com/xcms.php?r=oaeg-view-article&egart_uid=4b9f2a844034a the proposed explanation]] for how the minds of transapients work.

* Butcher XIV from ''Literature/{{Worm}}'' carries the consciousnesses of every previous bearer of the Butcher mantle.

* A downplayed and benign example appears in ''WesternAnimation/AtlantisTheLostEmpire'' with the Heart of Atlantis, which thrives on the collective emotions of all Atlanteans that pass on, providing its people with power, longevity and protection in return.
