* ''The Amtrak Wars'' by Patrick Tilley. The main protagonist Steve Brickman has an unconscious telepathic link with his kin-sister Roz so when he's wounded in battle she experiences the same injuries, though they vanish without trace in a few hours.

** In the original Marvel Comics [[ComicBook/TheTransformers Transformers]] series, Megatron and Ratchet ended up fused together after a freak accident. They were seperated, but Ratchet wound up seeing (and feeling) what Megatron did.

Two people are linked together, or a person is linked to an object, such that whatever happens to one also happens to the other. Killing or harming one of them will lead to the death or equivalent harm of both. You wouldn't think this would be desirable, but it works the other way too; see EmpathicWeapon.

** Sosuke Engulfing Shadow is a giant spectral mouth that he can eat LifeEnergy through, but damaging it will also damage his actual mouth or more.

* Played for comedy in Stephen Chow's ''Royal Tramp''. When Stephen finds out they're synchronized, he insists on "testing" them, taking one behind a curtain and leaving the viewer to figure out what he's doing by the reactions of the other one.

* In ''The Carpenter'', the ghostly carpenter is pained whenever his house is damaged. He's vanquished when the place is set on fire, which causes him to burst into flames.

* ''Literature/TimeForTheStars''. [[TwinTelepathy Tim links to his brother Pat]] for moral support while he's having a surgical operation. This means that when Pat is anaesthetized [[AndIMustScream his mind is still conscious]], while Tim feels both his brother's fear and the pain of the surgeons cutting into him.

%%* ''Literature/TheDragonCodices'': In ''Bronze Dragon Codex'', Tatelyn and Simle get this due to a Starjewel.

* ''Series/TheWheelOfTime'': Aes Sedai and Warders share a bond which results in one's condition affecting the other. For example, when an Aes Sedai falls unconscious it weakens her Warder. When Lan drinks alcohol, Moiraine becomes [[NotSoStoic noticeably emotional]].

* ''Series/TheWheelOfTime'': Aes Sedai and Warders share a bond which results in one's condition affecting the other. For example, when an Aes Sedai falls unconscious it weakens her Warder.

If the link can ensure the death of a participant but doesn't otherwise transmit pain or other feelings, then it isn't a Synchronization but a case of CantLiveWithoutYou. Compare PsychicGlimpseOfDeath, where one party experiences the death of another while connected to their mind but is able to survive. Compare RemoteYetVulnerable.

** The endgame reveals that [[spoiler:the BigBad of ''VideoGame/XenobladeChronicles'', Zanza, and the Architect of ''Xenoblade 2'' are two halves of the same person, so naturally when one of them dies, the other will die as well.]]

* ''Franchise/{{Pokemon}}'' has the ability "Synchronize", which works in that if the Pokémon with that ability gets [[StandardStatusEffects poisoned, paralyzed, or burned]], then their opponent gets poisoned/paralyzed/burned, too.

** Taken even further in ''Anime/DigimonTamers''. First shown with Takato who's strong bond with his partner Guilmon causes him to start feeling Guilmon's pain at certain times (starting with the battle with the tiger Deva Mihiramon) as well as allowing him to mentally and emotionally connect with Guilmon, at times even allowing him to lend Guilmon strength. [[spoiler: After the main trio Bio-Merge with their Digimon, they discover that all three of them feel now feel their partners pain when they fight the D-Reaper in the real world.]]

* Also used between the twins in Kate Forsyth's ''Witchever they do to something they also feel. Slap someone and you both feel the pain. Kill someone and you have a heart attack and die. Sit on a hoard of food while other starve around you and feel the pain of their hunger. The title of the story is the reverse of TheGoldenRule, attributed to Jesus of Nazareth in the Biblical book of Matthew: "Do unto others as you would have them do unto you."
