* ''Webcomic/GirlGenius'':Professor Beausoleil is a spark who created clank duplicates of himself to better carry out his duties. After reviewing the Van Rijn notes he got [[spoiler:as a reward for betraying Paris to The Other's forces]], they became so sophisticated that the sensations experienced by one were shared with the others and the flesh and blood Beausoleil. The page image above depicts him suffering the pain of death many times over as a result of his duplicates getting destroyed all at once. [[spoiler:He tries to smugly pass off his [[RewardedAsATraitorDeserves execution]] as a [[DeathIsASlapOnTheWrist minor setback]], as the last one in the city is [[ActuallyADoombot also a clank double]]. Then the new master of Paris informs him that the real Beausoleil will meet his own doom soon enough, what with him failing his real masters and all. The professor has no comeback to communicate through his proxy, which summarily gets destroyed as well.]]

* ''Manga/JoJosBizarreAdventureSteelBallRun'': [[BigBad Funny Valentine]]'s Stand allows him to swap bodies with any of his alternate universe counterparts.

* ''Film/EverythingEverywhereAllAtOnce'': The denizens of the Alphaverse have developed technology that allows them to access the skills, knowledge, memories, and even bodies of their parallel universe counterparts.

* ''ComicBook/SonicTheHedgehogArchieComics'': ''Sonic Universe'' #59 introduces Eclipse, a [[VideoGame/ShadowTheHedgehog Black Arms]] SuperSoldier created in [[EvilKnockoff Shadow's image]]. Shadow wipes out all of the Black Arms except Eclipse, who maintains a PsychicLink to Shadow through the Black Arms HiveMind, allowing him to mess with Shadow's head on occasion.

* ''ComicBook/TheAuthority'': The Engineer has a mental link to the duplicates of herself she creates using her {{Nanonmachines}}. She can create up to 82 duplicates, but going further will cause her personality to dissociate. The Engineer can also limit the mental connection between herself and her clones through concentration as seen by when she stopped herself and her other clones from experiencing an orgasm one clone had during sex with Jack.

* ''ComicBook/TheAuthority'': The Engineer can make duplicates of herself which are in mental contact with her. She can create up to 82 duplicates, but going further will cause her personality to dissociate. The Engineer can also limit the mental connection between herself and her clones through concentration as seen by when she stopped herself and her other clones from experiencing an orgasm one clone had during sex with Jack.

* ''Literature/TimeEnoughForLove'': Lazarus Long inadvertently has a pair of OppositeSexClone[=s=] (created in order to tempt him to stay alive after the boredom of literally 2300 years of life. Lapis Lazuli Long and her sister Lorelei Lee Long claim to possess this. It's never verified (and the other characters display an uncharacteristic lack of interest in exploring the phenomenon), but they do [[FinishingEachOthersSentences tend to finish each other's sentences]] and generally behave like SingleMindedTwins.

* Psychic access to the other's memories and knowledge.
* Having whatever damage one suffers inflicted on the other.

Compare TwinTelepathy.

* ''Manga/{{Naruto}}'': Duplicates created using the [[SelfDuplication Shadow Clone]] technique are linked to the original. For example, if the original gets hurt (or in Naruto's case, dons the Demon Fox cloak, which burns him), the clones will feel the same pain and possibly disperse. On an inverse note, if a clone is gathering nature energy and overloads, they will turn into stone, a fate that will befall the original as well.

* Being able to sense or track each other's presences across some distance.

* Being in tune with the other's emotions or physical well being.

This trope is quite common as a way of introducing complications to the already weird situation of having someone who looks exactly like you running around. If the character is dealing with an EvilDoppelganger or EvilKnockoff, this only adds to the danger they present. The doppelganger could be able to read the character's mind, allowing them to predict their actions or learn valuable information. If the doppelganger's well being is tied to a character, then killing them presents a risk and would necessitate finding a way to stop them without killing them. This can also serve as a metaphor for how our actions can affect others we don't know about.

** ''ComicBook/SpiderMan2099'': In the original version, Miguel can sense whenever any of his {{Alternate Sel|f}}ves dies. That feeling manifests as physical pain, and he also catches breif glimpses of their deaths.

*** ''ComicBook/XFactor2006'': [[spoiler:Jamie is killed by the demonic villain Bloodbath in issue #227. The next few issue show him returned to life and pulled into alternate universes where his counterparts are either dead or dying. This causes Jamie to ponder if his powers work by pulling other Jamie Madroxes from alternate universes.]]

* ''ComicBook/SonicTheHedgehogArchieComics'': ''Sonic Universe'' #59 introduces Eclipse, a [[VideoGame/ShadowTheHedgehog Black Arms]] SuperSoldier created in [[EvilKnockoff Shadow's image]]. Shadow wipes out all of the Black Arms except Eclipse, who maintains a PsychicLink to Shadow through the Black Arms HiveMind, allowing him to mess with Shadow's head on occassion.

* ''Fanfic/ACertainDrollHivemind'': The Sisters from of ''LightNovel/ACertainMagicalIndex'' (see the Anime section above for their entry) are the focus of this fic. The difficulties of keeping a private diary when one is part of a constantly active telepathic hivemind is lampshaded, and used as underline just how different the Sisters' thought processes are.

* ''Fanfic/ImNobody'': Sora is the original person, Roxas is his Nobody[[labelnote:Explanation]]his physical body moving idependently with its own will[[/labelnote]], and Xion is a Replica based on Sora's memories. They can all see each other's memories via in their dreams. This can be very useful when Roxas or Xion need information they wouldn't have otherwise, but it can also lead to very awkward situations, like Sora dreaming about that time Roxas and Tali made out.

* ''Film/EverythingEverywhereAllAtOnce'': The denizens of the Alphaverse have developed technology that allows them to access the skills, knowledge, memories and even bodies of their parallel universe counterparts.

* ''Literature/TheStainlessSteelRat Goes to Hell'': The main villain has dozens of copies of himself, all of which share one mind, since they were created by traveling to some universe that appears to duplicate everything on a [[QuantumMechanicsCanDoAnything quantum level]]. When one of Jim's sons goes through a portal to another universe, he suddenly seems to be in two places at once, having been connected in the same manner to his twin brother on the other side. This is {{Hand Wave}}d as the twins having been one cell at one point in their development. Finally, when both twins fall in love with the same woman, who also falls in love with both young men, she uses the villain's method to duplicate herself, thus allowing herself to be with both of them at the same time (still one mind but now shared by two bodies).

* ''Series/Charmed1998'': Most TimeTravel episodes had characters synchronized to their past-selves so that anything that happened to the past character happened to the time traveler as well. [[spoiler:Chris and Wyatt]] were the most notable examples of this.

* ''VideoGame/PrinceOfPersia'': Shadow Man is a dark copy of the Prince created by a MagicMirror. [[PuzzleBoss The pair are synchronised, so that if the Prince manages to hit Shadow Man, or vice versa, both take damage, and if he does kill Shadow Man, he dies as well]]. [[spoiler:The solution is to SheatheYourSword, and walk into him to perform a {{Doppelmerger}}.]]

* ''WesternAnimation/Ben10'': In "Divided We Stand", Ben unlocks a new alien form named Ditto who has the power of SelfDuplication. Any pain inflicted on one Ditto copy is felt by the others. In the very same episode, [[MadScientist Dr. Animo]] captures Ben while the latter is in Ditto form and copies the alien's duplication powers to give them to his latest creation. Unfortunately for Animo, the process also gave his creature Ditto's weaknesses, so when one died, all the other monster clones disappeared.

* ''Fanfic/ACertainDrollHivemind'': The Sisters from of ''LightNovel/ACertainMagicalIndex'' (see the Light Novel section below for their entry) are the focus of this fic. The difficulties of keeping a private diary when one is part of a constantly active telepathic hivemind is lampshaded, and used as underline just how different the Sisters' thought processes are.

[[folder:Light Novels]]
* ''LightNovel/ACertainMagicalIndex'': The Sisters are clones of [[ShockAndAwe Misaka Mikoto]] who can link together into a HiveMind using a weaker version of Mikoto's electromagnetic abilities.

* ''Manga/{{Mar}}'':Snow is Koyuki's counterpart in the fantasy world of Mar Haven (or in the case of the anime [[spoiler:her magically-created clone]]). They see each other's life in their dreams.

* ''[[Manga/JoJosBizarreAdventureSteelBallRun JoJo's Bizarre Adventure: Steel Ball Run]]'': [[BigBad Funny Valentine]]'s Stand allows him to swap bodies with any of his alternate universe counterparts.

** ''ComicBook/Spiderman2099'': In the original version, Miguel can sense whenever any of his {{Alternate Sel|f}}ves dies. That feeling manifests as physical pain, and he also catches breif glimpses of their deaths.

* ''Film/{{Us}}'': The Tethered and their human doppelgangers are "connected" in a vaguely defined way. The Tethered are made to mimic the lives of their surface counterparts, [[spoiler:as stated by Red who was made to marry Gabe's Tethered Abraham and give birth to children identical to Adelaide's children.]] The Tethered are also able to use their link to track their humans as seen throughout the movie.

This trope is quite common as a way of introducing complications to the already weird situation of having someone who looks exactly like you running around.

** ''Series/PowerRangersWildForce''[=/=]''Series/HyakujuuSentaiGaoranger'': [[{{Ninja}} Onikage/DoroDoro]] can make clones of people using their own [[LivingShadow shadows]]. He uses this ability to create the [[PsychoRangers Shadow Rangers/Shade DoroDoro]] to fight the Wild Force Rangers/Gaorangers. The Shadow Rangers are able to predict whatever moves the Rangers are about to make before they execute it and any damage inflicted upon them is reflected back on the Rangers. However, this connection appears to only be one-way as the Rangers can't predict the Shadow Rangers' attacks and the Shadow Rangers can damage them without being hurt themselves.

When Onikage tries to use his shadow clone ability on [[MonsterClown Jindrax/Yabaiba]], the latter [[MirrorsReflectEverything reflects]] the attack back on him using a MagicMirror. [[HoistByHisOwnPetard Onikage finds himself fighting his own shadow clone and is killed when the Rangers destroy the shadow clone]].
