History Main / TeleporterAccident

* ''WesternAnimation/TheFairlyOddParents'': In the episode "Booby Trapped", Timmy uses Cosmo and Wanda's wands to transport himself and Chloe to the rain forest. The wish results in them having their heads swapped. They try to fix it, and become ConjoinedTwins. A second attempt gives Timmy a kangaroo body.

* In ''Literature/CharlieAndTheChocolateFactory'', Mike Teevee's attempt to become the first person transmitted by television results him being shrunk to a few inches high.[[note]]The teleporter worked EXACTLY as expected. A comically large chocolate bar is sent first and it appears as a normal sized one.[[/note]]

* The ''WesternAnimation/PinkPanther'' once fused the pale guy with a flower and himself to a bee.

* Quite common in {{crossover}}s as a way of justifying how [[TrappedInAnotherWorld Party X gets into Alternate Dimension Y]].
* The ''[[Fanfic/TriptychContinuum Triptych Continuum]]'' has ''recoil'' as part of the built-in danger for [[WesternAnimation/MyLittlePonyFriendshipIsMagic unicorns]] who can teleport: arrival points must be kept clear of anything more solid than a few blades of grass (or an exceptionally thin-shelled ball), or the arriving pony will be displaced in a random direction until they find enough space for their body to arrive. (The good news is that the random direction is never ''down''.) But the farther they go to find that space, the faster they'll find themselves moving when they finally do appear -- which can send ponies rebounding off the walls, or worse. Teleporters don't go to a site they can't see or don't have memorized unless they're desperate, and rearranging the furniture in a safe point can break bones.
* ''FanFic/BetweenMinds'' [[LampshadeHanging lampshades]] the massive amount of examples in ''VideoGame/HalfLife'' seen below, and [[OriginalFlavor true to form]] has a few examples itself.

* In ''Fanfic/{{Frostbite}}'', Dalsh Ruul tries to {{invoke|dTrope}} this against Captain Kanril Eleya by having his men set up [[NoWarpingZone transporter scramblers]], but Eleya completely ignores his attempt to stall for time and beams in with an assault unit before the scramblers are online.

* Harry Potter story Fanfic/MakeAWish has this happen repeatedly to the Death Eaters. It's a combination of genuine accident and getting on the Portkey maker's bad side; Harry himself, as Mr. Black, is only involved by being in the general area of the accident.
* Fanfic/KhaosOmega uses this in an interesting way as his self-based OC Jet has only ever gotten [[Franchise/SonicTheHedgehog Chaos Control]] to work properly ''once'', and only because he couldn't use his preferred [[Franchise/DragonBall Instant Transmission]]. [[spoiler:He was called in to neutralize a rare side effect to a newly-obtained Raging Soul upgrade by Anise, who got said upgrade on ascending to a power Jet couldn't lock onto; Anise didn't learn until the following day, after further upgrading her new powers, that [[BornUnlucky her notorious bad luck]] forced her into her first pregnancy a year earlier than she was planning.]]

* Parodied in ''Film/GalaxyQuest'', The Thermians based their Teleportation technology off of [[ShowWithinAShow the old Galaxy Quest show]]; and as such: the only ones who could actually be teleported using it are the actors on the show, When Fred tests the teleporter on a pig-lizard creature, with disastrous results:

* WesternAnimation/SpongeBobSquarePants and Squidward got fused this way (and at the end, with others as well).

All of which ''pales'' in comparison to what could happen when the teleporter itself malfunctions. If the [[{{Phlebotinum}} Heisenberg compensators]] [[TechnoBabble are misaligned]], then you could come out as an inert mass of carbohydrates (or a ''[[AndIMustScream screaming]]'' mass of carbohydrates), or it might hiccup and create an EvilTwin of you. Then again, the device may work by taking a "short cut" through '''{{Hell}}''', so everyone who uses it will GoMadFromTheRevelation... and/or come out with an EldritchAbomination on their heels. The possibilities are endless, and more often than not they are irreversible.

* ''WesternAnimation/TheSimpsons'' Did It too in a "Treehouse of Terror" episode. Bart winds up swapping heads with a fly after fooling around with Homer's matter transmitter pods. Another episode had Professor Frink suffer a power outage while transporting Sir Isaac Newton to the present. What emerges from the teleporter is [[HalfTheManHeUsedToBe a pair of sizzling legs]]… which proceed to chase Frink around the room and kick him.
-->'''Professor Frink:''' Ow! OW! Sir Isaac’s legs are ''hurting!''

** And once again involving Odd and also Yumi, one time they end up materializing after a mission on Lyoko, they end up [[FreakyFridayFlip swapping bodies,]] with Jérémie unfortunately having to inform them that it will take him a day to resolve the issue, to Yumi's chagrin at the idea of having to sleep in Odd's body and having Odd parade about in her body scratching her bra and making a fool of himself. To make matters worse, the swap is shown to be unstable, requiring them to virtualize and swap back before it's too late.

* ''Film/AntiMatter'': A woman named Ana begins to have difficulty forming new memories, no longer feels hunger, and has other bizarre symptoms after a teleportation experiment. Her research partners who were working on the teleportation machine with her seem strangely unconcerned when her room is broken into by a person wearing a chimpanzee mask who steals her work, and they later seem to be {{Gaslighting}} her. She becomes convinced that she lost her soul when she was teleported. [[spoiler: It turns out she was accidentally duplicated during a teleportation test, and we have been seeing things from the point of view of the duplicate. She cannot form new memories and feels no hunger because she isn't a real person, she is just an echo of the real Ana made of light. The real Ana and her partners were hiding this from her because she kept forgetting she was a duplicate and [[CloningBlues getting distressed by the revelation.]]]]

* In ''Manga/GiantRobo'', this is the tragic side effect to Ginrei's teleportation power and why she will only invoke it as a last resort; every time she does it, she risks losing some bit of herself in the act. [[spoiler:By the final episode, half her body has disappeared.]] Her brother also appears to have this ability; whether or not he suffers the side effects is unknown since he hasn't used it since he himself used it as a last-second escape.

* In ''[[ComicBook/RobinSeries Robin]]'' the wannabe hero turned villain Dodge gained teleportation abilities when the prototype teleportation belt he stole from Star Labs malfunctioned and started fusing with him. He's shortly thereafter killed by disintegration in another teleportation accident when he tries to teleport someone who is using a teleportation device, the other person is knocked into a permanent coma.

* In ''WebVideo/SwordArtOnlineAbridged'', among the [[ObviousBeta many issues]] the titular game suffers from are its Teleport Crystals, items that simply don't work half the time, or worse, leave their users stretched out and tangled like a plate of spaghetti, or [[VideoGame/AssassinsCreedUnity a pair of floating eyeballs over a set of teeth]]. Unless that was both the same player.

* Parodied in ''Film/GalaxyQuest'', when Fred tries to teleport Jason up to the ship. He tests the teleporter on a pig-lizard creature instead, with disastrous results:

* The ''Series/DoctorWho'' two-parter episode "Silence in the Library"/"Forest of the Dead" featured Teleporter Accidents on a planet-wide scale, used deliberately like a lifeboat. [[spoiler:The main computer of the Library teleported everybody ''into'' her database in order to save them from evil shadowy pirahna particles.]]

* ''WesternAnimation/TheFairlyOddParents'': In the episode "Booby Trapped", Timmy uses Cosmo and Wanda's wands to transport himself and Chloe to the rain forest. The wish results in them having their heads swapped. They try to fix it, and become [[ConjoinedTwins]]. A second attempt gives Timmy a kangaroo body.

* ''WesternAnimation/TheFairlyOddParents'': In the episode "Booby Trapped", Timmy uses Cosmo and Wanda's wands to transport himself and Chloe to the rain forest. The wish results in them having their heads swapped. They try to fix it, and become [[ConjoinedTwins.]] A second attempt gives Timmy a kangaroo body.

* The Philadelphia Experiment was [[UsefulNotes/ConspiracyTheories supposedly]] a US Navy-sponsored attempt to develop an InvisibilityCloak for a destroyer escort. The story goes that the ship successfully vanished for a period of time, then returned with some of its crewmen [[BodyHorror stuck through the bulkheads.]] This was said to be the experiment that produced the Chronosphere in ''VideoGame/CommandAndConquer: Red Alert'', and [[HandWave the reason]] infantry units are vaporized instead of teleported.

* ''VideoGame/{{Doom}}'' has teleporters that use hell as a stop over. HilarityEnsues. It's also the game that introduced the TeleFrag.

* ''Wiki/SCPFoundation''. [[http://www.scp-wiki.net/scp-761 SCP-761 ("Slightly Less Dangerous Trampoline")]]. When someone jumps on the trampoline they are subjected to TeleportationMisfire and end up in a random location within 15 meters. If there is already a solid object where they arrive they become merged with the object. Depending on how much of their body is merged with the object they can suffer a TeleFrag.

* In ''VideoGame/LibraryOfRuina'', W Corp is a [[MegaCorp Wing]] whose Singularity involves teleportation and this technology is what backs their famed WARP Trains. One plotline details a train ride that went wrong with the occupants [[spoiler:being stuck inside for 2000 years as they slowly go crazy and maim one another, unable to truly die no matter how much they're battered]]. Later chapters reveal [[spoiler:this is actually averted. While there was some interference, the event overall was no accident and is how WARP Trains normally operate. W Corp's true Singularity is restoration, which they use to revert the passengers to their original states while they're left non the wiser]].

* In ''WesternAnimation/StarTrekLowerDecks'', HistoryRepeats as Boimler has a transporter clone created due to a distortion field screwing with the transporter beam. Ironically, it happened twenty years (canon-wise) after Riker's clone was created ''and'' Boimler had used Riker's incident as inspiration to save his away team.
** Pictured above, in an earlier episode, Boimler ends up stuck phasing when he helps Rutherford test his upgrade to the transporter beam. It ends up causing him to be a little translucent, glow blue, and produce an annoyingly loud ringing sound (though Rutherford manages to fix the noise). It wears off by the end of the episode, though Mariner and the crew of another ship go through the same issue, though they also turn out fine later.
