->''"They are a unit; they even share the same name."''
-->-- Description of '''[=MasterBlaster=]''', ''Film/MadMaxBeyondThunderdome''

Two (or more) characters who, for all intents and purposes, act as one character, always appear together and are never introduced individually. Even if there are frequent disagreements between the members of The Dividual, they will act as one entity as soon as the {{Plot}} moves on.

There are two types:

* '''The Twindividual''': The individuals making up The Dividual are near-identical or very similar in at least one but usually several aspects (appearance, character traits, way of talking, job etc.). Sometimes, the twindividuals' members differ in some conspicuous way (for example: [[FatAndSkinny one fat, one skinny]]) but are still uniform in all other ways. FinishingEachOthersSentences is not uncommon among twindividuals.
* '''The Syndividual''': The individuals of which The Dividual consists have different looks and character traits but form a symbiotic relationship. Often their character types complement each other in some (comedic) way. They might have a division of labor thing going on, for example with one character being the spokesperson of the dividual.

The defining characteristic that sets a syndividual apart from a twindividual is the symbiotic aspect: a twindividual is just a homogenous crowd while a syndividual has a specific shtick with distinct roles. As a rule of thumb, twindividuals are based on the principle of BirdsOfAFeather while OppositesAttract in syndividuals.

Typically, The Dividual is a background character or part of an EnsembleCast but another frequent setup is something similar to an AdventureDuo where the two main characters form a dividual. This setup heavily restricts the available plots as the two main characters must always act as one in relation to other characters. In those cases, the work's name will often be simply the characters' names, "Alice and Bob"-fashion.

Might overlap with HeterosexualLifePartners, ThoseTwoGuys and/or ThoseTwoBadGuys. SingleMindedTwins is a subtrope. Compare LiteralSplitPersonality, HiveMind and IAmLegion. If the members of The Dividual are twins, expect any number of TwinTropes (especially SingleMindedTwins) to be in place. Sometimes, The Dividual will exhibit TwinTropes despite the fact that its members are not twins. For a romantic couple that is often referred to by a single name, see PortmanteauCoupleName.




[[folder:Anime & Manga]]
* [[OutlawCouple Isaac and Miria]] from ''LightNovel/{{Baccano}}'' share an entry on [[Characters/{{Baccano}} the cast page]]. People within the series get the same impression as well, so much so that the mere fact that Miria shows up to the Genoard mansion alone in ''Alice in Jails'' alerts Jacuzzi's gang that something has gone ''very'' wrong (namely, that [[spoiler:Isaac was arrested and sent to Alcatraz]]).
* ''Manga/{{Black Lagoon}}'' has the 'vampire twins', going by Hansel and Gretel, who go so far as to switch clothes and names. After one dies, the other one even goes so far as to imitate the other's voice. They're widely considered some of the creepiest characters throughout the series.
* ''LightNovel/{{Durarara}}'' (from the same author as ''LightNovel/{{Baccano}}''):
** Mairu and Kururi are twins who don't even consider themselves as individuals. [[Characters/DurararaAnimeSupporting They too share an entry on the cast page]].
** [[ThoseTwoGuys Walker and Erika]] also count. They share [[Characters/DurararaMainCharacters an entry on the cast page]] as well.
%%* Emi and Yumi from ''Anime/IrresponsibleCaptainTylor''.
* ''Manga/OuranHighSchoolHostClub''[='=]s Hikaru and Kaoru Hitachiin appear to be interchangeable, and in fact it later becomes a minor plot point that [[spoiler: no one can tell them apart except Haruhi]]. They occasionally exhibit signs of being annoyed by this, but mostly seem to accept that to everyone else, they are a collective.
** Later in the series, however, the two begin to diverge from each other, and even start to hit notes of SiblingYinYang - once Kaoru starts to realize [[{{Deconstruction}} how dangerously codependent they've become]] and how limited they've allowed their world to be. Once they start to act individually it becomes apparent that Kaoru is [[RedOniBlueOni much more reasonable and calm]], if somewhat self-deprecating, and Hikaru is more aggressive and selfish, mostly because of his {{Tsundere}} personality; in other words, their TricksterTwins act was some compromise between them, making Kaoru less pleasant and Hikaru more.
* [[BrotherSisterTeam Sora and Shiro]] take this [[UpToEleven to the extreme]] in ''LightNovel/NoGameNoLife''. They're nearly invincible when playing together, but if they get separated even briefly they'll instantly have nervous breakdowns.
* ''Anime/SevenOfSeven'' has three {{Jerkass}} romantic rivals who often act and speak in unison, in addition to the [[LostInTranslation eponymous]] character who's a LiteralSplitPersonality.
* The HalfIdenticalTwins from ''Anime/YuGiOh5Ds'', Luca and Lua, are often treated as one character, which is even reflecting in the name of Team 5D's. While this is partially true and the twins do have a very strong bond, this trope is often subverted. For most of the time, Lua is treated as an extra to his younger sister Luca, mostly because of him being not a Signer until the GrandFinale. Lua is also given more screen time and character interactions, despite Luca being technically more important to the plot and setting than her brother.

[[folder:Comic Books]]
* Dupont and Dupond from ''Franchise/{{Tintin}}'' (Thomson and Thompson for the English-speakers).
* ComicBook/DisneyDucksComicUniverse: Huey, Dewie and Louie. The fact that they have all the exact same personality, and are impossible to tell apart without their hats, means that they're basically one boy with three bodies. The early comics even had their dialogue as one speech bubble with three arrows, when they weren't FinishingEachOthersSentences instead. The ''WesternAnimation/DuckTales'' cartoon subverts this in one episode, when Dewey decides to leave The Dividual when frustrated that no one outside their family can tell them apart, but still sticks to it for the most part. [[AvertedTrope Averted]] in ''WesternAnimation/QuackPack'' and ''WesternAnimation/DuckTales2017''.
** Interestingly, the ''[=DuckTales=]'' reboot ''does'' poke fun at the triplets' dividuality from the comics:
---> '''Lena:''' That's cute, with the names and the color-coded outfits... is that your thing, you're all exactly the same?
---> '''Huey, Dewey, & Louie:''' [[SpeakInUnison Ha, no way! We're all unique snowflakes...]] Well, this usually never happens! This is really weird! Okay, stop talking! (beat) {{Antidisestablishmentarianism}}! Seriously?! GAH!
* {{Non Player Character}}s Bartémulius and Nostariat from ''ComicBook/{{Noob}}''.
* In ''Comicbook/LegionOfSuperHeroes,'' Triplicate Girl's alien race the Carggites have the natural ability to split into three identical bodies. In most continuities, each group of three is treated as a Dividual. But the Post Zero Hour version of Triplicate Girl, named Triad, was persecuted by Carggite society because her three selves had distinct personalities (one aggressive, one submissive, and one balanced between the two). Her aunt secretly had the same condition and claimed that this was actually the natural state for Carggites, and that their culture's insistence on making each person's parts act like a Dividual was cruel and harmful.
* MarvelComics villains the Blood Brothers are two bulky alien twins, who's powers are based on how close they are to one another. Leading to this trope to the fullest.

[[folder:Films -- Animation]]
* The Bimbettes (Gaston's fangirls) trio in ''Disney/BeautyAndTheBeast'' are, for all intents and purposes, a single entity.
* Ruffnut and Tuffnut from ''WesternAnimation/HowToTrainYourDragon'' are fraternal twins so similar, aside from respectively being female and male, that their choice of a two-headed zippleback as a dragon steed could be foreseen from the film's beginning. They're so accustomed to living and working side by side that background dialogue in one scene has Ruffnut fail to recognize her own twin, because she's ''sitting on the wrong side'' of Tuffnut for a change.
* Thumper's sisters in ''Disney/{{Bambi}}'' are a Twindividual: they all look and act identically to each other, to the point where both the [[Disney/BambiII midquel]] and ''Disney's Bunnies'' series drop a sister with absolutely no change to the dynamic. They aren't even given individual names outside of the latter.

[[folder:Films -- Live-Action]]
* The albino ghost twins in ''Film/TheMatrixReloaded''. They're identical twins that dress alike, fight in concert and can't seem to say an entire sentence without the other's help. As they're constructs of the Matrix, they're probably either one partially corrupt program or copies of each other. The trios of Agents do a lot of this, too.
* Mr. Wint and Mr. Kidd from the ''Film/JamesBond'' film ''Film/DiamondsAreForever''. They hang out together, they work together, they are ''always'' together.

* ''Literature/HarryPotter'':
** Fred and George, the Weasley twins. Fred is the more outgoing one and George is slightly more reserved, but it's easy to miss considering they share a love of colourful pranks and are almost always together. Until ''Deathly Hallows'', that is, [[spoiler:when George is nearly killed and Fred has to deal with his brother's potential death. Then George gets his taste of this when Fred is actually killed.]]
** Example of characters who are not literal twins: Crabbe and Goyle, two big Slytherin boys who basically exist to follow Malfoy around looking menacing and laughing at his jokes. This lasts until book seven, [[spoiler: where Crabbe develops a bigger nasty streak than Malfoy or Goyle.]]
* "Samneric" from ''Literature/LordOfTheFlies''. That's right, the two are referred to by ''one name.''
* The At Dawn twins from ''Literature/GivesLight''.
* The clone society in ''Literature/WhereLateTheSweetBirdsSang'' by Kate Wilhelm likes to view its various clone "families" this way. Their society starts to fall apart when a few members start to rediscover individuality.
* In the sci-fi detective novel ''Emissaries of the Dead'', the cylinked twins Oscin and Skye Porrinyard are this. They're very similar in appearance, except that one is male and one is female, and through cybernetic modification, they essentially have one merged consciousness.
* WordOfGod notes that [[CoDragons the three Ravers]] of the ''Literature/ChroniclesOfThomasCovenant'' are like this; Donaldson envisioned them as "perfect minions" and so never bothered giving them distinct personalities or motivations, so they'd be completely interchangeable; as far as the plot is concerned, they might as well be one creature that can be in three places at once. To add another layer, they're also all pretty much lesser copies of their boss, [[BigBad Lord]] [[GodOfEvil Foul]].
* Uncle Prudent and Phil Evans are a syndividual in Creator/JulesVerne's ''Literature/RoburTheConqueror''.
* Caramon and Raistlin in ''Literature/{{Dragonlance}}'', at least at the start. Sure, their personalities are different, and sure there's a lot of one-way arguing going on, but the moment there is danger, they take action like a single person.
* This trope's OlderThanPrint: Sir Gareth and Sir Gaheris from ''LeMorteDArthur'' and various other Arthurian legends are the two youngest Orkney brothers. Aside from Gareth's brief stint as hero of his own tale in Malory's version, the two are so closely associated that it's not always clear which one is speaking, which barely matters as they're never shown to hold a separate opinion and even ultimately die in the same way for the same cause. In some versions they even marry near-identical sisters, though their wives' personalities very much reflect SiblingYinYang, in contrast to their own closeness in temperament. Some scholars now believe that this might be due to Gareth and Gaheris starting out as a single character who got divided in two due to a transmission error.
%% * Shaunee and Erin from ''Literature/TheHouseOfNight.'' They even ''refer'' to each other as Twin, and the only real significant difference between them is that Shaunee is black and Erin is white.
* Irri and Jhiqui, the handmaidens to Daenerys Targaryen, from ''Literature/ASongOfIceAndFire''. They are nearly always mentioned together, they share the same CatchPhrase, and are more or less interchangeable.
* ''Literature/PercyJacksonAndTheOlympians'' give us Travis and Connor Stoll, the Joint Head-Counselors of the Hermes Cabin. They aren't twins, but they might as well be, as no one seems to be able to remember who's older and who's younger, and they look very, very similar. They're also unrepentant pranksters (not surprising given their godly parent) making them rather like the Weasley Twins in Literature/HarryPotter
* Scorch and Leff in the eighth book of the ''Literature/MalazanBookOfTheFallen''. While Scorch seems perpetually surprised by everything, Leff is more on the suspicious side, but otherwise they seem a lot alike and they always act and are perceived by others as one entity, and mostly serve as comic relief. Until they turn out to be surprisingly competent.
* Ultimately subverted in ''Literature/HorusHeresy''. As mentioned in Tabletop Games section, Alpharius and Omegon are publicly known as one person, called, appropriately, Alpharius Omegon, and they are both SingleMindedTwins and capable of seamlessly pretending to be one another, but as the Heresy goes on, there's a bigger and bigger gap growing between the two.
* Craig and Fry, the insurance detectives from Creator/JulesVerne's ''Literature/TribulationsOfAChinamanInChina''. The two were an inspiration for Tintin's Thompson and Thomson, although these are quite competent. They're never seen away from each other, never referred to separately, alternate words to form complete sentences, and don't even bother talking to each other as they have the exact same thoughts.
* In Marcel Aymé's collection of short stories ''Les contes du chat perché'' (translated as ''The Magic Pictures'' and ''The Wonderful Farm''), the parents of the protagonists (two little girls) are handled as a single entity for everything they do and say, with only one or two occurrences of only one of them speaking. Even when they grab something the girls had been hiding, the narrative mentions that they hold it with their four hands. The girls themselves are close to be a syndividual, as they seldom do anything separately, but they at least have different names and personalities.
* The Ruzzo brothers from ''Literature/TheVampireFiles'' are Chicago gangsters who look so much alike, and so seldom work apart from each other, that their fellow-gangsters refer to them in the singular as often as the plural (e.g. "Tell Ruzzo to get their butt in the car, already.")
* Gestalt from ''Literature/TheRook'' is the extreme version of this trope: four siblings who, collectively, are Gestalt. As in one being with four bodies, constantly seeing through eight eyes. Apparently Gestalt can make the four adopt different mannerisms around people who don't know they're a hive mind, but we never see them bother to be anything other than lockstep creepy in the novel.

[[folder:Live-Action TV]]
* Twins Cody and Logan from ''Series/{{Baskets}}'' are always seen and mentioned together, following up seamlessly on what the other says, working together as a DJ act and lacks TwinDesynch in contrast to their very, very different elder twin brothers.
%%* The different Cylon models in ''Series/BattlestarGalacticaReimagined''.
* ''Series/DoctorWho'':
** The Osgoods, introduced in [[Recap/DoctorWho50thASTheDayOfTheDoctor "The Day of the Doctor"]], are a human woman and a [[VoluntaryShapeshifting Zygon]] that originally impersonated her for nefarious purposes. They ended up getting along swimmingly, and made themselves into symbols of the peace treaty between humans and Zygons, refusing to tell anyone which was which. In [[Recap/DoctorWhoS34E12DeathInHeaven "Death in Heaven"]], [[spoiler:the Master killed one of them, but the survivor ''still'' refused to spill the beans. Eventually, another Zygon [[Recap/DoctorWhoS35E8TheZygonInversion took the place]] of the dead Osgood.]] They still refuse to tell anyone which is which. They even have a PsychicLink so what one knows, both know. (According to Ingrid Oliver, their actress, it ''is'' possible to tell which Osgood is which -- and she and the writers know -- but no one has been able to figure it out yet.)
* ''Series/KamenRiderDouble'', fittingly, has two examples, one of each type:
** [[ThoseTwoGuys Detectives Makky and Jinno]] are the Syndividual, constantly disagreeing and arguing in funny ways but rarely seen apart except in the movies.
** High school students [[NamedAfterSomebodyFamous Queen and Elizabeth]] are the Twindividual: nearly indistinguishable, completely inseparable, and treated by the plot as a single character.
* ''LiveAction/MightyMorphinPowerRangers'': Bulk and Skull ''could'' appear separately, but it would fall flat as they feed off each other so much that neither alone functions as a character. To be fair, there were two other punks (a chick with messy hair and a black guy) that hung out with them early on, but they [[ChuckCunninghamSyndrome vanished without explanation]] after appearing in two episodes and had ''no'' lines ''at all''.
* ''Series/PowerRangersRPM'' has Gem and Gemma, a pair of [[HalfIdenticalTwins half-identical]] [[SingleMindedTwins single-minded]] twins who can't even talk without [[FinishingEachOthersSentences the other around]]. Well, until she gets a boyfriend, after which the HiveMind breaks whenever he's involved.
* ''Franchise/StarTrek'':
** The [[MeaningfulName Bynars]] of ''Series/StarTrekTheNextGeneration'' are a species of twindividuals.
** In ''Series/StarTrekDeepSpaceNine'', "twinned Miradorn" (presumably there are non-twinned ones to whom this doesn't apply) are considered two halves of the same being. When one is killed before the other, the surviving twin calls his mourning a "loss of self," and his only purpose left in life is to avenge his twin before joining him in death.
* The trio of jocks from ''Series/StudentBodies''. The cartoon shots even depict them as a single person with three heads.
* Ed and Larry from ''Series/TheWestWing''. It was occasionally lampshaded that the main characters couldn't remember which of them was which.
* Scully and Hitchcock from ''Series/BrooklynNineNine'' are basically [[Series/ParksAndRecreation Jerry Gergich]] if he suddenly became twice as incompetent and mitosed into two people. Additionally, Hitchcock's basic lack of individual identity also seems to seep into his conversations, since in one scene, the entire precinct are unable to figure out if the person he's been talking about the whole time is his wife ''or his dog.'' It's implied this might not be the first time that's happened.

[[folder:Tabletop Game]]
* ''TabletopGame/Warhammer40000'' gives us Alpharius Omegon, the Primarch of the Alpha Legion. In reality they were Alpharius and Omegon, who were identical twins and are described as "two bodies, but one soul". As their combat doctrine focused on espionage, deception, and covert ops, force they frequently switched places for their own ends; and to complicate matters, the entire Alpha Legion ''also'' looks like them, and one of their calling cards was that each one identified themselves as "Alpharius". When they interacted with other members of the Imperium formally, Alpharius was the public face, while Omegon's existence was one of the best kept secrets in the galaxy. This is so extreme that one, both, or neither of them may have died shortly after the Heresy, and no one knows which.
* ''TabletopGame/VampireTheMasquerade'' had a Sabbat only artificial bloodline [[MadScientist created by Tzimisce]], the Blood Brothers. They actually straddle the line between Twindividual and Syndividual, since Blood Brother groups tended to have more than two members, who would look identical, have similar personalities and generally act as one organism, to the point of [[BodyHorror lending each other blood, limbs and other body parts]].

* The River City School Board in ''Theatre/TheMusicMan'': Ewart Dunlop, Oliver Hix, Jacey Squires and Olin Britt. As Harold Hill says, "you'll never see one of those men without the other three."
* The two "Nieces" in ''Theatre/PeterGrimes'' almost never do anything separately, and sing mostly in unison, harmony or canon with each other.
* Exaggerated in ''Theatre/TheGondoliers'' by Creator/GilbertAndSullivan, where Marco and Giuseppe become the King of Barataria until it can be settled which one of them it really is, and they make comical attempts to act "as one individual."
* Rosencrantz and Guildenstern from [[JustForFun/TheZerothLawOfTropeExamples Shakespeare's]] ''{{Theatre/Hamlet}}'' are treated as this. Their interchangeability and uniformity is hinted at by Shakespeare in the very choice of their names, which exhibit the same metric properties and ethnic background. Their dividuality is further [[PlayingWithATrope played with]] in ''Theatre/RosencrantzAndGuildensternAreDead'', to the point that two characters can't agree on which one is which.

[[folder:Video Games]]
* ''VideoGame/DevilMayCry3DantesAwakening'' gives us [[{{KillItWithFire}} Agni]] and [[{{BlowYouAway}} Rudra]] - a pair of [[{{EmpathicWeapon}} sentient demonic swords]], who first appear as DualBoss. When defeated, they offer their services to main character in slicing, dicing, [[{{ArsonMurderAndJaywalking}} and occasionally commenting on combos he pulls off while using them]]. Even then those two are indivisible - you can't equip them in any way other than simultaneous dual-wielding.
* Elle and Ille from ''Anime/RioRainbowGate'', twin girls in PlayboyBunny outfits who work at a Casino. Ille always repeats the last word/phrase Elle says.
* Thorn and Zorn from ''VideoGame/FinalFantasyIX''. In fact, they're ''literally'' one person, as shown when they rejoin into Meltagemini for their boss fight.
* Morris and Derek, background dancers from ''VideoGame/EliteBeatAgents''.
* [[VideoGame/IceClimber Popo and Nana]] in their appearance in ''VideoGame/SuperSmashBros'', though they weren't like this in their original game.
* The Twins in ''VideoGame/TheCave'' control and act exactly the same as any single other character. Careful study of their movements raises the question of whether there still really ''are'' two of them or if by the present date one has been replaced by a life-size ventriloquist's dummy.
* The Luteces, brother-and-sister inventors of Columbia's floating city technology in ''VideoGame/BioShockInfinite'' always appear side by side, snarking at each other and at Dewitt. They are identical in almost every way, same clothes, same mode of speech, same age, same builds - except one is male (Robert) and one is female (Rosalind). [[spoiler:It's later revealed that they're not brother and sister. They're the same person but from different dimensions - one born male, one born female.]]
* Team Jump from ''VideoGame/ThomasWasAlone''. They are identical squares sharing all the same abilities and being entirely interchangeable. Team Jump is inseparable, to the point where they do not even appear to have individual names. They are simply Team Jump. They pride themselves on their teamwork, and overcome obstacles together to advance as a single unit.
* The [=DeWynter=] Sisters in ''VideoGame/SaintsRowTheThird'' seem to have this relationship - never being seen without one another and operating as co-right hands to Loren. [[spoiler:At least until Kiki's death, that is. However, they're reunited in Hell in SaintsRowGatOutOfHell.]]
* ''Franchise/{{Neptunia}}'': Rom and Ram are PolarOppositeTwins, but they are almost always together. Their core personalities are reflections of their older sister's two extreme character traits, the twins have almost identical movesets, have basically the same weapons and matching costumes, they get upgrades at the same time and they join the party at the same time. Their goddess forms are even more of a PaletteSwap than they already are in their human forms, and they share the same divine name: White Sister.
* In ''VideoGame/{{Broforce}}'', the Boondock Bros (an {{Expy}} of ''Film/TheBoondockSaints'') count for all intents and purposes as one character, despite being two people. They are controlled similarly to the Ice Climbers in ''VideoGame/SuperSmashBros''.

[[folder:Visual Novels]]
* [[ThoseTwoGuys Virus and Trip]] from ''VisualNovel/DramaticalMurder'' are often seen together, share a bad ending together, dress as the exact opposite of each other's outfit, work in the yakuza, and are both [[spoiler:leaders of Morphine and [[InLoveWithYourCarnage dangerously obsessed with Aoba]]]].

[[folder:Web Comics]]
* The Cotyorites (Proxenus, Nicarchus, and Clearchus) from ''Webcomic/TheLydianOption'' are highly similar looking members of a philosopher race that appear together (and complete dialogue together).
* From ''Webcomic/TheOrderOfTheStick'', the [[Characters/TheOrderOfTheStickDivineBeings Inter-Fiend Cooperation Commission]] is composed of Lee (a devil), Nero (a daemon) and Cedrik (a demon) that always talk and act as a trio. They're basically interchangeable, and despite being supposedly of different evil alignments, don't really have distinct personalities. Sabine describes their team dynamic in strip #903, but they'd still be identical without the color-coding.
* In ''Webcomic/SandraOnTheRocks'', minor characters Adrianne and Adrienne, Eva's fashion stylist and hair and makeup expert respectively, form a classic twindividual.
* ''Webcomic/StandStillStaySilent'': Håkan, Sune and Anna Västerström, the children of the couple behind the expedition. They all have BrattyHalfPint as their main character trait and are always acting together in their antics, which makes them quite a handful for any adult trying to deal with them alone.

[[folder:Web Original]]
* Bartémulius and Nostariat from ''Franchise/{{Noob}}'', the pair of InsufferableGenius alchemists that are a recurring QuestGiver and EscortMission charge in the franchise. The only time Bartémulius was seen alone was in the webseries version, when Nostariat's actress couldn't show up for filming. While they are FatAndSkinny in addition to being different sexes, their lines of dialogue tend to be quite similar.
* ''WebAnimation/{{RWBY}}'': The twins Carsac and Fennec Albain. They act and are reffered to as an unit rather than two separated people.

[[folder:Western Animation]]
* Andy and Ollie Pesto from ''WesternAnimation/BobsBurgers''.
-->'''Andy:''' Back to you Ollie!\\
'''Ollie:''' Back to you Andy!\\
'''Andy:''' Back to you Ollie!
* ''WesternAnimation/TheSimpsons'':
** Terri and Sherri from , the CreepyTwins in Bart's class. It's never made clear which is which. They even go to the model UN as Trinidad and Tobago (a single country). However, they do insist that they're individuals, and Bart apparently has a crush on one of them. One episode even uses the line "Sherri, but not Terri" as a gag by itself.
--->'''Both:''' I'm Sherri, she's Terri.
** Rod and Todd Flanders, despite a two-year age gap.
* Katie and Sadie from ''WesternAnimation/TotalDramaIsland'' aren't related, but they look and act so similar that they could be mistaken for twins.
* Dee Dee from ''WesternAnimation/BatmanBeyondReturnOfTheJoker'': twins so of one purpose that they're only considered a single supervillain.
* ''WesternAnimation/{{Superjail}}'''s Twins are always together and display identical personalities and motives. It's shown that trying to separate them or make them ''not'' do something together will only upset them.
* Tad and Chad from ''WesternAnimation/TheFairlyOddParents'' are almost identical twins except [[SaltAndPepper one of them is white and the other is black]] and are usually treated like a single person. In one episode they both ran for class president as a single candidate and won.
%%* The Bully Brothers from ''WesternAnimation/ThePerilsOfPenelopePitstop''.
%%* ''WesternAnimation/KingLeonardoAndHisShortSubjectsDuke'': and Earl, King Leonardo's twin nephews.
* Peepeye, Poopeye, Pupeye and Pipeye, the lookalike nephews of WesternAnimation/{{Popeye}}. In the Famous Studio shorts, their verbal tic was starting a sentence then sending it to the next down the line to the last person for completion.
* ''WesternAnimation/CodenameKidsNextDoor'' has various examples of this trope:
** Mr. Fibb and Mr. Wink, two HeterosexualLifePartners who attacked using special chairs. They're never seen apart, even when they're not doing villainy, like watching TV. Of course, they're based on Mr. Wint and Mr. Kidd from ''Film/DiamondsAreForever''.
** Taken UpToEleven, however, are the five Delightful Children from Down the Lane. They are five kids from different families, but they function as an individual. They stick close enough together that they're in physical contact with each other, never separate (except on two occasions, which become major plot points for those episodes), occupy the same seat at school, and even speak in unison. The only reason why they aren't a HiveMind is that their actions and reactions become different from each other when panicked -- otherwise, they're on identical mental wavelengths.
** From the twin variety, there's the Interesting Twins from Beneath the Mountain, who despite being brother and sister and having distinct personalities, they invariably act as a team. It helps that the shade on their faces make each one resemble half of a Yin-Yang.
* ''WesternAnimation/StevenUniverse'': The [[PlanetOfSteves three Ruby]] [[ExpendableClone bodyguards]] shown in "The Answer" are identical in all but the placement of their gemstone and have very similar personalities. When they [[FusionDance fuse]] together the resulting Gem is basically nothing more than a bigger Ruby. The one who would later become a major cast member ends up setting herself apart and defects from Homeworld. In season 3, another group of five Rubies are introduced in the episode "Hit the Diamond," known now by the fanbase as 'The Ruby Squad,' and in the Wanted arc that ended season 4 we are also introduced to a pair of Topazs [[spoiler: who may like being fused a bit too much for Homewold's tastes]]. Both of these groups also fuse to become larger versions of themselves in their respective episodes.
* ''WesternAnimation/TheVentureBrothers'' has several pairs who are usually seen together (and apparently they tend to be based to some extent on the show's two [[AuthorAvatar creators]]), but the only ones who really come off as inseparable are the Guild agents Watch and Ward. Henchmen 21 and 24 began as a Dividual, but eventually they developed out of it.
-->'''Henchman 21:''' Hey, you think you could sign this, boss? It's for 24. He got knifed by the Moppets.\\
'''The Monarch:''' Which one is 24 again?\\
'''Henchman 21:''' What? You're kidding, right? Let me give you a hint. You know how every time you talk to me, there's usually another guy next to me? That's 24.
* ''WesternAnimation/G.I.Joe'' The twin employers of Extensive Enterprises are this; best noticed when they are speaking. The only way to tell them apart is Xamot's facial scar.
* Frix and Frax in ''ComicBook/BuckyOHareAndTheToadWars''. The Toad Air Marshal's twin assistants almost never appear separately.


[[folder:Anime & Manga]]
* The Light Card and the Dark Card in ''Manga/CardcaptorSakura''. You can probably guess what they do. They wear white and black, respectively, but look similar (with RapunzelHair crowned in metal, and elegant gowns featuring AbsoluteCleavage) and have identically graceful, refined manners. Cardcaptors must engage them as a unit. They ask to be sealed together, and Sakura does so.
* Muto Ashirogi in ''Manga/{{Bakuman}}'' is a two man team consisting of Moritaka Mashiro and Akito Takagi, who have been nigh inseparable since middle school. Mashiro is an artist and Takagi is a writer, and most of the other authors in ''Magazine/ShonenJump'' (Or ''[[BlandNameProduct Shonen Jack]]'' in the anime) treat them similar to a single entity.
* The protagonists of ''LightNovel/NoGameNoLife'', Blank, cannot be apart or they'll suffer something similar to withdrawal symptoms. However, the pair is basically unstoppable when together. To emphasize this, the two are dissimilar to each other in terms of everything, such as age, gender, colour scheme, specializations, etc.
* ''Anime/SenkiZesshouSymphogear G'' introduces Shirabe and Kirika, both having Symphogears originating from the same goddess. As such, their battle songs are meant to be mixed together, so they can sing in duets. They are nigh-inseparable in ''G'', but their individualities clash with each other during the climax of the season. Then in ''GX'', they seem to lose any individuality except their opposite, but matching character traits.
* ''Manga/OuranHighSchoolHostClub''[='=]s Honey and Mori. They both have their own personalities and their own "charm" to attract girls, but they often work as a set that functions by making TheStoic and quiet Mori look more approachable and friendly by having the small and cute Honey around (Tamaki even describes the look as "a big bear that befriended a little rabbit"). It's not uncommon for Mori to carry Honey around in his shoulders either. It helps that they are cousins too.
* ''Anime/SailorMoon'': Uranus and Neptune; the two were explicitly designed as a pair by Takeuchi and it shows. The two are always introduced as a pair, never get solo songs in the Theatre/SeraMyu, only duets, and the times they're seen apart can be counted on one hand, and never appear in an episode/chapter/musical without the other. When they're forcibly separated for an episode in Sailor Stars, Uranus remarks on how weird it is to not have Neptune with her. While there are jokes that one of them often lacks a personality (normally Neptune) that doesn't revolve around the other among fans, the two are fleshed out as individuals but half of it is word of god or doesn't get to shine for any length of time.

[[folder:Comic Books]]
* ''ComicBook/GoldDigger'': One issue in the TournamentArc featured a "duo individual", which basically means that a punch-specialist and a kick-specialist can literally band together and complement each other's strengths, in a duel no less. The only drawback is that separating the two is an automatic win condition, something that one of the specialists has to be yelled at about before she stops the gluttonous "overtime".

[[folder:Comic Strips]]
* Richandamy from ''ComicStrip/{{Zits}}'' are an extreme example: they're only physically separated when they HAVE to be (such as separate classes), and have been seen literally contorting and stretching superhumanly to be together even then. During a temporary breakup the others were literally ''unable'' to call them by their separate names, as in it caused Jeremy physical pain to do so.

[[folder:Films -- Animation]]
* [[EnthrallingSiren The Dazzlings]] from ''WesternAnimation/MyLittlePonyEquestriaGirlsRainbowRocks''. They all have distinct looks and personalities (Adagio is the [[ManipulativeBastard scheming]] [[AlphaBitch leader]], Aria is the [[DeadpanSnarker snarky]], surly [[BetaBitch second-in-command]] and [[EnsembleDarkhorse Sonata Dusk]] is the [[{{Cloudcuckoolander}} spaced-out]], [[TheDitz ditzy]] one and obviously the bottom of the heap), but they're never seen apart and function, story-wise, as a single unit.
%%* In ''WesternAnimation/{{Ratatouille}}'', {{invoked}} by Remy and Linguini, who deliberately become this.

[[folder:Films -- Live-Action]]
* Film/TheViewAskewniverse as created by Creator/KevinSmith has Jay and Silent Bob.
* In ''Film/MadMaxBeyondThunderdome'', "[=MasterBlaster=]" is literally treated as one person, until the title character unmasks the pair for what they are. [[BrainsAndBrawn Master acts as the brains and Blaster acts as the brawn.]]
%%* Creator/LaurelAndHardy.
* ''Film/TheManWithTheIronFists'' features the Gemini Killers, male and female, always shown together and unstoppable as a pair as their fighting style is entirely based around working as a single unit. Their motif features the Yin-Yang symbol heavily.

* ''Literature/{{Neverwhere}}'' has [[MisterXAndMisterY Mr. Croup and Mr. Vandemar]], ThoseTwoBadGuys. They take their partnership seriously enough that [[spoiler:when Mr. Croup is sucked through a gateway into deep space, Mr. Vandemar voluntarily follows him.]]
* Bone and Chair, the stand-ins for TheMadHatter and the March Hare in Patrick Senecal's ''Aliss.'' Bone, the more intelligent of the two, is in charge, while Chair provides the muscle. They're very much ThoseTwoBadGuys, and their arrival on any scene generates a guaranteed OhCrap, given the [[BodyHorror usual result]].
* Gestalt from The Chequy Files: The Rook is actually one person in multiple bodies.
* In ''None But Man'' the Moldaug society and mentality is based on three Moldaug working in sync with one another to form a single individual.
* Stephen and Sandra Farraday, a married couple from ''Sparkling Cyanide'' by ''Creator/AgathaChristie'', act as a syndividual to other characters, who remark on how it's always "the Farradays" and neven Stephen or Sandra. The reader gets to see a bit of disagreement behind the scenes, though.

[[folder:Live-Action TV]]
* ''Series/{{Seinfeld}}'' Jerry and George try to pull this off for one episode to be a woman's boyfriend. Jerry does the actual dating while George manages schedules and anniversaries. George's theory was that the two of them working together might be able to accomplish the tasks of one normal man.
-->'''Jerry:''' Then each of us would only have to be, like, a half-man.\\
''[George nods]''\\
'''Jerry:''' ...That sounds about right!
* Creator/PennAndTeller, on TV, in film, on stage, etc. They're so closely associated in all media that it's almost a subversion to see them separate, for example, Penn on his personal video blog or Teller lecturing at conventions.
* ''Series/BetterOffTed'': Phil and Lem, the lab workers. Often used explicitly as a gag.
** Veronica refers to them at one point as "Mustache and Glasses," despite the fact that it's Lem who has both.
-->'''Ted:''' First of all, "Mustache and Glasses" are ''the same person.''
* In ''Series/AgentsOfSHIELD'', Agents Leo Fitz and Jemma Simmons spend enough time together that they are referred to by pretty much everybody (up to and including Director Fury) as "Fitzsimmons" (and occasionally it's "Fitzsimmons ''is''..." rather than "Fitzsimmons ''are''..."). They even sort of refer to themselves this way, using "we" a lot and automatically operating under the assumption that they feel the same way about everything (e.g. "He was our favorite professor"). Although they are both scientists, they fulfill separate roles, specializing in engineering and biochem, respectively. Their personalities are also shown to be [[RedOniBlueOni opposing but complementary]] in many respects.
* ''Series/{{Scrubs}}'':
** {{Invoked}} in the episode "My Fairy Tale", where Carla and Turk merge into one annoying two-headed monster.
** Turk and J.D. are such inseparable friends that in one episode it is joked that, in college, Turk dated an Indian girl who only went out with him because she thought his last name was [[AsLongAsItSoundsForeign "Anjaydee"]]. (This is strictly InUniverse, though, as J.D. and Turk are actually the main characters and both have a lot of individual depth apart from being each others' best friends.)
* An episode of ''Series/CriminalMinds'' has the [=UnSub=] as a trio of construction workers who stick close together, travel together, and murder individuals one by one by mobbing them. Even when confronting the FBI at the end, they remain in roughly the same place, never separating more than a few meters apart. They are defeated when one of them is accidentally shot and killed, severely demoralizing the other two enough to allow the FBI to easily corner and arrest them.
%%* [[CampGay Julian and Sandy]] from ''Radio/RoundTheHorne''.

[[folder: Video Games ]]
* Sam & Max have this dynamic in the ''VideoGame/SamAndMaxFreelancePolice'' game series. Sam is generally the character controlled by the player (until the third season of the Telltale games, when the player takes control of Max when his newly-discovered psychic abilities are called for), but both ''VideoGame/SamAndMaxHitTheRoad'' and various episodes of the Telltale games require Max to solve a puzzle (in ''Hit the Road'', he can actually be used as an item).
* Game units will sometimes be syndividuals, for example the Goblin Alchemist HeroUnit of ''VideoGame/{{Warcraft}} 3'', a goblin carried around by an ogre. The ogre hits things and the goblin throws potions, and both get speaking lines. Same with Dwarf mortar teams from the Alliance.
%%* Reno and Rude from ''VideoGame/FinalFantasyVII''.
* ''VideoGame/{{Disgaea 3|AbsenceOfJustice}}'''s Kyoko Needleworker and Asuka Cranekick, Raspberyl's GirlPosse.
* Gomar and Shioh, drivers of the Twin Noritta from the ''VideoGame/FZero'' games. Their whole race takes this trait, where as soon as they are born they pair up with another individual and become partners for life (or until married). They actually needed special permission to become F-Zero racers because the rules usually only allow one pilot per machine.
* Mr. Right and Mr. Left in ''Videogame/IMissTheSunrise''. Even their names imply they are never seen apart.
* DualBoss Gorc and Pic from ''VideoGame/DarkForcesSaga''.
* ''VideoGame/MapleStory'' has Zero, a pair of twins who make up a single playable class. Their individual names are Alpha and Beta, although you'd never know it given how rarely they're referred to as separate entities outside of their story quest.
* This is the case with Zen and Rei in ''VideoGame/PersonaQShadowOfTheLabyrinth'' - they function as a single unit, and only take up a single spot in the party roster. Zen casts offensive magic, while Rei casts curative magic. [[spoiler:Late game spoilers reveal that Rei could only use her curative magic when she's near Zen, as said magic was originally Zen's to begin with. Also, after the player completes the fourth labyrnth, Rei is kidnapped and Zen becomes a standalone party member.]]
** Also the case for Ken and Koromaru in ''VideoGame/Persona4Arena''.
* Many of the characters in ''VideoGame/NamcoXCapcom'' belong to this trope.
** In its sequel, ''VideoGame/ProjectXZone'', ''every'' independent unit is a Dividual. Solo units do exist, but must be "equipped" to a dual unit in order to take part in battle. In that game's sequel, [[Franchise/AceAttorney Phoenix Wright and Maya Fey]] are combined into one solo unit, making this a straighter example.
* In the ''VideoGame/SuperSmashBros'' series, the character of VideoGame/DuckHunt (or Duck Hunt Duo in Europe) consists of the duck, the dog and the hunter, all playable as a single unit.
* In ''VideoGame/HotlineMiami2WrongNumber'', Alex and Ash are siblings that are controlled as a single unit, with Alex standing in front with a chainsaw and Ash behind her with guns. If one of them dies, the other drops their weapon and surrenders.
* ''VideoGame/MortalKombatX'' has Ferra/Torr, a small child-like female riding upon a large hulking brute. Ferra is the one who does the talking while Torr does the smashing. Their ending reveals them to be members of the same species in different stages of life: Ferra will eventually outgrow Torr and become just as big as him, serving as the mount to another small creature.
* ''VideoGame/SuperheroLeagueOfHoboken'' has Zaniac and Toastbuster, a crimefighting duo who joins your league near the end of the game. They're complete opposites, both in looks and abilities (Zaniac is incredibly brainy, while Toastbuster is pure brawn) but insist that they're in fact twin brothers. The good doctors at the Richard Nixon Memorial Hospital wouldn't have lied to them, would they?
* Two playable characters in ''VideoGame/GranblueFantasy'' function like this (Morphe/Phoebe and Dorothy/Claudia). Since they're both two characters in one party member slot, each one has their own set of three skills with different effects and a shared fourth skill to swap out the current for the other. The Maids Dorothy and Claudia also have the effect of going to 200% meter for their charge attack.
* Kindred from ''VideoGame/LeagueOfLegends'' represents the twin essences of death; Lamb's arrows are quick and painless for those who accept death, whereas Wolf chases down and devours those who run from their fate.
** Interestingly, in their bio Kindred is the only champion whose 'Friends' section contains themselves.
* Shayne and Aurox from ''VideoGame/{{Battleborn}}'' are a 16 year old punk ActionGirl that's somehow bonded to an EldritchAbomination RockMonster. Together, the two function as one playable character.
* Gremolitions, Inc. from ''VideoGame/AtlasReactor'' are two [[OurHomunculiAreDifferent gremunculi]] called Idd and Odd who ride together on a hoverbike with a giant mortar.
* ''VideoGame/BodyBlows'': Of the extraterrestrial fighters introduced in ''Body Blows Galactic", Dino is a Velociraptor-like creature who fights along with a smaller green creature that rides on its back. Some moves allow for the use of a FastballSpecial by launching the rider or having the raptor hold down an opponent and let the rider do a close range beat down.
%%[[folder:Web Comics]]
%%* Zimmy and Gamma from ''Webcomic/GunnerkriggCourt''. Given a deconstruction, to an extent. Zimmy goes to lengths to make Gamma subservient to her.
%%[[folder:Web Original]]
%%* Slash and Agito from ''Roleplay/DarwinsSoldiers''.

[[folder:Web Video]]
* The Healthy Band from ''WebVideo/DontHugMeImScared 5'' mostly act as one individual, and there's not much distinction between the four of them aside besides appearance. They do frequently contradict each other, but then they contradict ''themselves'' as well, and no-one in-universe comments on it.

[[folder:Western Animation]]
* Carl and Lenny from ''WesternAnimation/TheSimpsons'' span the whole range of this trope. Early on the show they form a borderline twindividual (different looks but identical nondescript characterization), later on, they sometimes were treated as a bickering syndividual (and HeterosexualLifePartners), and at some point, the writers decided to deconstruct their dividual to facetiously emphasize the characters' (non-existent) individuality - only to reconstruct it for a throw-away gag in the next episode.
* The title characters of ''WesternAnimation/PhineasAndFerb'' are almost always together and, while both technical and creative geniuses, have nearly opposite personalities (Phineas being [[CheerfulChild active and talkative]], Ferb being [[TheQuietOne passive and mostly silent]]).
* ''WesternAnimation/EdEddNEddy'':
** The other kids seem to think of the Eds as interchangeable. When one of the protagonists does something to anger the other kids, they'll punish the three uniformly despite their lack of involvement. Additionally, when they attempted to join the Urban Rangers, they were given one chance for each badge for the three of them.
** [[AbhorrentAdmirer The Kanker Sisters]] look different enough from each other to raise questions about whether they're biologically related... and sure enough, their intro episode makes it clear that they all have different fathers. It still doesn't stop them from being nearly identical in behavior in the early episodes. The youngest one, May, starts to break the mold a bit later on.
* [[ThoseTwoGuys Walter and Perry]] in ''WesternAnimation/HomeMovies'' almost always dress alike, have very similar high-pitched voices, and are always seen together, [[AmbiguouslyGay usually holding hands.]]
* The Weird Sisters on ''WesternAnimation/{{Gargoyles}}'' always show up, act, and are treated as a single unit. Each of them, however, is somewhat specialized- [[HairOfGoldHeartOfGold Phoebe]] symbolizes grace, [[MysticalWhiteHair Luna]] symbolizes fate, and [[EeriePaleSkinnedBrunette Selene]] symbolizes vengeance. Which of the three is directing the Sisters' actions [[WildCard varies]].
* [[RedOniBlueOni Ruby and Sapphire]] in ''WesternAnimation/StevenUniverse'' look and act very different, but are basically inseparable. In a more literal interpretation of functioning as a single character, they spend the majority of their time [[FusionDance fused together as one person]].

* Television presenters Creator/AntAndDec. British audiences have been watching them for decades and are still not completely sure which one is which. Their inseparability was perhaps best summed up by the comedian Creator/MarcusBrigstocke (whilst remarking on an otherwise unrelated topic).
--> "The relationship between war and religion is a lot like the relationship between Ant & Dec. You could have one without the other, but I'm not sure anyone would see the point."
