History Main / Synchronization

* In the ''WesternAnimation/JackieChanAdventures'' fanfic ''Fanfic/TheUltimateEvil'', it would seem like that two people who are [[WonderTwinPowers Others]] to each other can feel each other's pain in extremely painful situations. Most often it happens between Shendu and Valerie, like when Shendu is rendered unconscious for being in touch with the [[KryptoniteFactor Pan'Ku Box]] and Valerie is blasted in the face with [[PlayingWithFire the Dragon Talisman]].

* ''Wiki/SCPFoundation'', [[Characters/SCPFoundation [=Characters/SCPFoundation=]]], [[http://www.scp-wiki.net/scp-607 SCP-607 ("Dorian")]]. When SCP-607 bonds with someone, anything that happens to it (physical or emotional) will also happen to that person. It also happens to be [[DrivenToSuicide suicidal]], which means anyone it bonds with will not last much longer.

** From ''Battle Network 4'' onwards, it becomes a gameplay effect: Damaging enemies just before they attack causes this, which gives you double damage on your next attack. It's even more extreme in the manga, where the consciousness of the Operator and Navi actually merge. In addition, any damage done to the navi in the virtual world is transferred to the operator, be it a small cut, a dismembered limb, or full-out deletion/death. The concept in general is taken a bit further than usual, with Full Synchro being explained as [[TechnoBabble eliminating the delay between a command being issued and it's execution]], which is absolutely necessary to the most powerful of the autonomously operating Net Navis, who don't have such a delay in the first place.

** As noted, the empathic link between a wizard and familar (or another character with an animal companion/paladin mount) is usually too weak to count as full synchronisation. However, there is a Corrupt spell, "Master's Lament" from ''Heroes of Horror'', which can strengthen this link to the point that any damage or magical effect suffered by the familiar or the master will be transferred to the other.

* On ''Series/TheXFiles'', a woman who'd escaped a child-abductor as a girl experiences spontaneous injuries, because she's Synchronized with the kidnapper's latest victim. [[spoiler: She winds up drowning on dry land when the abductor attempts to kill his captive by submerging her in a river. The young girl survives, with no sign of the injuries which had been transferred to the woman.]]

* One of the comedy skits from the original ''Series/TheElectricCompany'' had two brothers inflicting pain on themselves that the other would feel until the both of them collapsed.

* When Kami [[EnemyWithout separated his evil side and forced it out of him]], it eventually became [[MadeOfEvil King Piccolo]]. Unfortunately, he went on a rampage and killed thousands of people ForTheEvulz, but Kami couldn't let him die, because if he died, Kami would also die. After Goku mortally wounded King Piccolo, he spat an egg out with his essence that carried on the Synchronization. It eventually hatched into Piccolo Jr, who was linked to Kami just like his father was. Eventually, they fused together again after Piccolo underwent CharacterDevelopment and a HeelFaceTurn.

* In ''Anime/{{Pokémon}}'', Ash's Greninja [[spoiler:has access to a unique SuperMode known as Ash-Greninja when Ash and Greninja synchronize their strong feelings a a trainer and Pokémon. This forme allows Ash to see battles from Greninja's point of view and causes Ash and Greninja to share eachothers pain. ]]

Frequently goes hand-in-hand with a PsychicLink, because YourMindMakesItReal, and sometimes with MindLinkMates. Compare MySignificanceSenseIsTingling. Often [[PowerPerversionPotential exploited]] for [[DirtyMindReading very]] [[FetishFuel interesting]] [[RuleThirtyFour effect]]. See also SharedLifeMeter, a related video game trope. RealityAffectingMiniature is a variant of this, where an object or person is linked this way with its representation.

** A limited variant of this applies to Shadow Clones. If said clone is gathering nature energy and overloads, thus [[TakenForGranite turning into stone]], the creator will suffer the same fate.

* In ''Film/TheAvengersAgeOfUltron'', twins Quicksilver and Scarlet Witch are linked this way (at least, Scarlet Witch, as {{The Empath}}, feels what Quicksilver feels. It's never mentioned whether the link goes both ways). When [[spoiler: Quicksilver dies,]] it doesn't do the same to Scarlet Witch, though judging from the way she screams when it happens, it was pretty bad for her, too.

* In ''Franchise/DragonBall'', [[PhysicalGod Kami]] and King Piccolo are synchronized in such a way that if one dies, the other does as well. This is because they are manifestations of the respective good and evil consciences of a Namekian who used a fission technique to purge himself of all sin and become God. When Goku eventually kills King Piccolo, the latter creates an egg whose embryo contains his memories & personality. Because of this, when Piccolo Jr. hatches from the egg, ''he'' is now synced to Kami, and continues to bear this burden until he & Kami [[FusionDance re-fuse]] in the Cell saga.
** Strangely, this aspect is absent in the case of Majin Buu's Good, Evil, and Kid forms and Guru & Lord Slug. The latter can be ignored due to Lord Slug being non-canon, but the case of Majin Buu is left unexplained.

** In ''ComicBook/TransformersLastStandOfTheWreckers'', Topspin and Twin Twist have "vicarious preception" (basically a fancy name for this trope). [[spoiler:Eventually, Twin Twist ends up being tortured by Decepticons, and the other Wreckers are at a computer where the password-bypass system is for someone to sacrifice themselves. Topspin decides, knowing that his brother is in serious pain anyway, to [[HeroicSacrifice offer himself to the computer]].]]

* ''Webcomic/GirlGenius'': Gil and Tarvek wind up synchronized by a "Si Vales Valeo" procedure intended to save Tarvek's life. And then Agatha comes down with the same disease Tarvek has, which means she gets hooked into the procedure as well.

* Back when he was Impulse, [[TheFlash Bart Allen]] acquired the power to create energy duplicates of himself. When one of them died during ''OurWorldsAtWar'' he went into psychic shock. While he recovered, he was extremely reluctant to use the power after that.
