"Enterprise, what we got back didn't live long... fortunately."In The Future, no life insurance agency will ever cover Teleporter Accidents. Why? Well to start, it may accidentally send you to Alpha Centauri instead of Mars in a mis-jump, or if you slip you could suffer a Portal Cut and end up cut in two, then again if it's not there you'll suffer a Portal Slam as you hit the concrete, which is still far less painful than being teleported into solid matter and suffering a telefrag. All of which pales in comparison to what could happen when the teleporter itself malfunctions. If the Heisenberg compensators are misaligned, then you could come out as an inert mass of carbo-hydrates (or a screaming mass of carbo-hydrates), or it might hiccup and create an Evil Twin of you. Then again, the device may work by taking a "short cut" through Hell, so everyone who uses it will Go Mad from the Revelation... and/or come out with an Eldritch Abomination on their heels. The possibilities are endless, and more often than not they are irreversible. Compare and contrast with Teleportation Sickness, where the process is merely uncomfortable... or at least whatever effects it has, even if bad, are not caused by it malfunctioning. (And yes, there is an overlap in a minority of cases.) Related to Came Back Wrong if you subscribe to the theory that a teleporter kills the original and recreates a perfect quantum copy at the chosen location. For purposes of trope differentiation, teleporter related mutations caused by beaming with or into another organic being go in Tele-Frag. If it's because of the beaming itself, it goes here. Not to be confused with a Porting Disaster.

Anime and Manga
- In Noein, the Dragon Knights run this risk each time they travel between dimensions. Kuina has it particularly bad, inevitably losing another chunk of himself with each transport; the only one to suffer worse is a Red Shirt who dies in the first episode when he arrives with half his body missing.
- This is referenced and mocked in the very first issue of Hiroshi: Strange Love, after the titular Mad Scientist invents a teleporter. According to his assistant, "One, you'll probably end up fusing someone with an animal, two, you'll end up trapped between spaces, or three, your mind will switch with someone else's . . ." It's number one—the assistant merges with a stray cat.
- In Gantz, sometimes it happens that the very slow teleporting process creates a clone of a person. One of the girls gets doubled this way, with the original unaware of what her clone has to suffer.
- Super Dimension Fortress Macross gets its initial plot kicked off by a major Fold accident: in desperation to escape Earth and draw the attacking Zentradi away, the Macross attempts to Fold to the dark side of the Moon. They wind up Folding to the orbit of Pluto instead, and take most of South Ataria Island, not to mention two aircraft carriers, with them. And they have to come back to Earth the long way, because the Fold engine disappeared in transit.
- In Giant Robo, 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. 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.
- A variation occurs in Cable & Deadpool: the two characters genetic code got mixed up beforehand, leading to Cable's transporter fusing them together every time they use the wrong command.
- The character Misfit in Birds of Prey is regarded by Oracle as potentially one of the most powerful teleporters in the world, since she avoids so many of the problems associated with teleportation: she never transports into the same place as another object, she has no effective range limit, she heals any bodily injury during transportation and she never needs to concern herself with different environmental factors between her origin and destination). However, despite her abilities, she can not bring any living being with her when she "bounces." If she tries, they explode immediately after transport.
- Which is why she wasn't able to save her parents from dying in a fire. Or maybe she DID, but...
- MAD did a Star Trek parody during the original series run, and naturally Kirk in the transporter ends up reassembled...oddly - a hand where a foot should be, another hand sticking out of his ear... Kirk's head replaced his torso, so you basically have Kirk's lower-body/legs with his head on top with the above mentioned silliness. Both Kirk & Spock see it as a mild annoyance & Kirk states, "I have the strangest feeling that my face wants to sit down".
- Quite common in crossovers as a way of justifying how Party X gets into Alternate Dimension Y.
- The Triptych Continuum has recoil as part of the built-in danger for 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.
- Between Minds lampshades the massive amount of examples in Half-Life seen below, and true to form has a few examples itself.
- In ''Frostbite' Dalsh Ruul tries to invoke this against Captain Kanril Eleya by having his men set up transporter scramblers, but Eleya completely ignores his attempt to stall for time and beams in with an assault unit before the scramblers are online.
- Referenced in Last Rights. Petty Officer Chan Salris of the USS Bajor wishes one on Kobali General Q'Nel for wanting to turn several fallen Bajor crew members into Kobali. (The author's been very vocal on Star Trek Online's forums about his opinion that the Kobali are Designated Heroes of the self-delusional war criminal variety.)
- Event Horizon. The teleporter sent the ship to a really unpleasant place, and from there it Came Back Wrong, while its original crew left a nightmarish ship log before disappearing.
- In the 1958 film The Fly and the more obscure short story it was based on, the scientist André Delambre successfully teleports himself over a short distance but discovers that he has been merged with an unseen housefly that entered the telepod with him. The process of dematerialization and reconstitution combined his molecular structure with that of the fly. He emerges with the head and arm of the fly, and vice-versa.
- The 1986 remake by David Cronenberg has both accidental teleporting and telefragging. The animals that Seth Brundle sends through his teleporter come out "synthetic", inside out, and die in terrible pain. His own experiment with the teleporter doesn't go well either: a fly enters the chamber with him, and the two are merged together. Body Horror results. In the climax, Brundle-fly tries to become more human by repeating the experiment with himself and his pregnant girlfriend. Stathis saves her by damaging the equipment, which causes pieces of the telepod itself to be teleported and merged with Brundle-fly instead.
- In Star Trek: The Motion Picture, quoted atop the page, the Enterprise's new science officer and one other crewmember are killed in a transporter accident; their bodies had begun to materialize in a disfigured manner, with the other officer shrieking in pain, before their signals were pulled back to the Starfleet Command transporter.
- Parodied in Galaxy Quest, when Fred tries to teleport Jason up to the ship. He tests the teleporter on a pig-lizard creature instead, with disastrous results:
- In The Prestige, Nikola Tesla succeeds in creating a teleporter... sort of. What really happens is that it creates a copy at the desired location, without destroying the original.
- This could be considered a negative number of teleporter-related deaths. Except that Angier sets up all his originals to be drowned.
- In Spaceballs, President Skroob reluctantly uses a transporter even though he's scared of them. His fears are realized when he materializes and his head is facing the wrong way. He's transported back to "fix" the problem and we find out he only needed to walk to the next room, anyway.
- The Doom film has Pinky, a character who has a wheelchair for a lower body. "He went to one dimension, his ass went to another."
- Dungeons & Dragons: Wrath of the Dragon God has a mage teleporting the party in such a way her arm gets stuck in a stone wall. It had to be cut off before teleporting away. The scrying mirror she used to divine the teleport location was slightly flawed; its inventor put himself all the way into a wall.
- Looney Tunes: Back in Action has a scene where Mr. Chairman transports the main characters to his office. However, a glitch causes several of their body parts are switched around (ex. DJ has Bugs' tail, Kate has Daffy's legs, etc.). This is fixed shortly afterward.
- A driving plot point in Big Hero 6. Long before the events in the film, Krei's company developed a teleporter machine inside a laboratory on an island near San Fransokyo and put on a demonstration with a military captain, with Professor Callaghan's daughter as the test pilot. Despite the device being slightly unstable, Krei continued with the experiment, until a malfunction caused one of the teleporter portals to be destroyed after the pilot went in through the other portal, trapping her inside the portal dimension, forcing Krei to stop the demonstration and causing the laboratory to be shut down by the government. Callaghan, furious at Krei for supposedly killing his daughter, sought revenge against him and is later revealed to be Yokai, whose ultimate goal was to destroy the Krei Tech Industries building by sending each and every piece of it (along with Krei) through a newly constructed portal.
- Fantastic Four (2015) has Reed Richards' teleporter being the source of the team's powers - just before Reed, Ben and Johnny are teleported back to earth from Planet Zero, rocks get in Ben's pod, fire gets in Johnny's pod, and when it is teleported back, Sue gets caught in the blast radius.
- The odd, murderous creatures that the would-be documentary makers in Devil's Pass encounter are results of being warped by teleportation. To be more specific, the creatures are the two final cast members who took a blind jump into a teleporter, and were send into the past.
- The Star Challenge books have this as one possible outcome of warping -how is named there teleport-. the nasty effects range from being sent elsewhere in space and/or time, usually to bad places, to funny stuff such as being ripped apart, becoming a sprinkling of atoms across the entire galaxy.
- A couple of relatively mild ones happen in Artemis Fowl: The Lost Colony in the time-tunnel. Artemis and Holly each wind up with one of the other one's eyes, and No 1 loses a couple megabytes' worth of memories.
- Lampshaded, but not used, in The Hitchhiker's Guide to the Galaxy. In The Restaurant at the End of the Universe there's an anti-teleporter Protest Song that goes:
I teleported home one night,
With Ron and Sid and Meg.
Ron stole Meggie's heart away,
And I got Sidney's leg.
- Arthur C. Clarke's short story Travel by Wire wryly outlines some of the problems inherent in teleportation, with the system's designer admitting that he'd far rather travel by rocket.
- In Interesting Times, Ponder Stibbons does go into excruciating detail about the risks of it happening (e.g. ending up inside a mountain, that kind of thing). The calculations come off much better than that, but Instead of just swapping Rincewind and the "Barking Dog" again, they accidentally send Rincewind to XXXX. The kangaroo he replaces is teleported to the university and ends up laminated against a wall. Ponder figures out a Technobabble explanation for this.
- While scrambling into action at the climax of the second Time Wars novel, several people are teleported to exactly the same time and place. The resulting monstrosity is reported to be mercifully short-lived.
- Played straight, and averted in a Ciaphas Cain novel. A squad of World Eater Berserker Marines are teleported in front of Cain and co. These Berserkers are fine and butcher their way through hordes of Slaaneshi cultists. However, the foot notes mention that teleporting is inaccurate, especially when done through a planet (as was the case here). It's likely that there are dozens of World Eaters entombed in solid rock from near misses, unless the cultists' Summoning Ritual helped.
- Harry Potter: Apparating (a witch or wizard's ability to teleport from one place to another anywhere, anytime) is far from safe. It actually requires a license and weeks of painstaking (sometimes literally) training to perform legally. If one apparates without their fullest concentration, splinching occurs. Splinching is when the person teleports, but they leave a little bit of themselves behind. Sometimes it's something tiny, like an eyebrow. Other times, it's something big like a freaking leg!! It's extremely painful all of the time.
- Then there's the Floo network, which requires stating your destination while stepping into a fireplace. If you don't pronounce your destination clearly, like Harry did the first time, you'll end up somewhere else. Traveling by Portkey is also unpleasant.
- In book 2 of Jade Blonde: The heroine and her friend travel by satellite like TV signals would, Split into a thousand pieces and put back together at their destination. While they knew it was experimental they did not expect to switch voices and right arms.
- In Star Trek: Genesis Force, the Aluwnans manage to save 10% of their population from the deadly Genesis Wave by storing them as transporter patterns in a series of satellites. When it comes to rematerializing them, the process is delayed when one individual comes out as a bloody heap of flesh - contaminants in the system were responsible.
- In another Star Trek novel, a Betazoid scientist loses his wife during a routine transport to another transporter station on Betazed due to an unpredictable solar flare that scrambles the beam.
- An old sci-fi story dealt with aliens coming to Earth and offering to share their technology which includes teleportation with humanity. Unfortunately, the alien civilization is stagnant, and has been for centuries ever since the discovery of the teleporter, as the alien interacting with humans and studying their 'quaint' beliefs in souls and psionics learns that souls do exist and anyone who's been run through a teleporter loses his soul and all that's left is a souless shell. Without souls all development and creativity had stopped for them and to save humanity from that (apparently he was unwilling or didn't believe his people would believe the truth) the alien destroys his ship and all records in their database referencing Earth. It ends with a reporter detailing the story and sadly thinking how he'll never again create anything new, as he was part of the group of humans run through the teleporters to show that they were safe.
- Another early sci-fi story involves an elderly owner of a business needing to get to the Moon for an important meeting where he was going to be removed from his position due to his absence. He uses a teleportation technology to make it which transports only soft tissue, as evidenced by the rabbit. Bizarrely enough, both he and the rabbit have absolutely no problem or pain just oozing around afterwards...
- A short story by Stephen King called "The Jaunt" describes a method of teleportation in which those who use it must be sedated. Although the reason why is alluded to early on, it becomes horribly apparent to the reader when the narrator's son avoids taking the sedative; it turns out that going through the Jaunt while conscious causes the mind to experience a millennia-long span of time in a few seconds. Needless to say, this is a bad thing..
- Secret City has this weaponized: a mage powerful and/or skilled enough can crush other mage's portal mid-teleport, grinding anything passing through to Pink Mist at best.
- "Counter Foil" by George O. Smith is a short story where the ubiquitous teleporter system breaks down. People go in, but suddenly people stop coming out.
- Done intentionally by Picard in Star Trek: Federation to get rid of the Big Bad (at this point little more than a computer entity) for good. He orders the transporter set to "maximum dispersion, maximum range" and beams the computer carrying him off the ship.
- In the Perry Rhodan Series, this is what happened to one of the main characters, Alaska Saedelare. The accident merged him with an alien, disfiguring his face in such a way that everyone who saw the horrible squirming thing he now had for a face went mad immediately and died shortly after.
- In Charlie and the Chocolate Factory, Mike Teevee's attempt to become the first person transmitted by television results him being shrunk to a few inches high.
- Iain M. Banks's "The Culture" universe features short-range teleport devices known as "Displacers". Except in dire emergency, they are only used to transport inanimate objects because of the risk of this (the risk is in fact vanishingly small from a human perspective, but still unacceptably high from the point of view of the controlling AIs). Ironically, since transporting inanimate objects is not usually very exciting, most of the times we actually see them used they are transporting living beings (without ill effect).
Live Action TV
- Transporter Accidents are recurring plot devices in various Star Trek series. Which makes several characters' insistence to the safety of the procedure rather bizarre. As any viewer can tell you, when transporters mess up, the result rarely are pretty. Perhaps, like air travel, they're very safe except when they really aren't. Usually, the more difficult the transport, the more likely side effects occur. Transporter malfunctions have been known to:
- Create a clone of an individual (Riker).
- Merge two people and a plant together (Neelix and Tuvok) into one distinct being. Then unmerge them through the power of mad science!
- In a funny bit of Fridge Logic, the plant they were with never gets unmerged, so Neelix and/or Tuvok is part plant from this point on in the series.
- Cause people to get transporter psychosis, going nuts. Implied to be the result of putting the complex structures or chemical balance of the brain back together just slightly wrong. O'Brien waved aside fears about that in The Next Generation as ridiculous, saying that it was rare to begin with and a new case hadn't been reported for a century (i.e. since the original series) due to improvements in transporter technology.
- Split one entity into good and evil entities.
- Mix certain non-corporeal entities together with a person.
- Send people to alternate universes or realities.
- Send people back in time.
- Beam people inside solid rock or out into open space, if the coordinates are set improperly.
- Outright kill people.
- Being unable to re-materialize and thus being stuck in the pattern buffer having to exist as a hologram.
- According to Chakotay, re-materialization without clothes has happened...which considering the alternatives is getting off very light.
- De-age people back into kids (they found a way to reverse it, of course).
- Though part of an experiment, the 2009 Star Trek film has mention of Admiral Archer's prized beagle failing to re-materialize.
- A deleted scene would have shown the beagle re-materializing aboard the Enterprise at the very end.
- Being stuck in the buffer too long so your pattern has degraded too much to be rematerialized.
- In the first season of Star Trek: Enterprise, the transporters hadn't gotten all the kinks out and weren't certified for transporting people. In an emergency, a Red Shirt was transported from the surface of a planet during a windstorm and arrived with leaves and twigs embedded in his body. Luckily he would make a complete recovery, which for a redshirt is amazing.
- Another episode has a scientist attempting to perfect the means of interstellar teleportation. Previous attempts have resulted in his disfigurement (and having a metallic spine) and his son being stuck in a beam.
- Note that despite all this, in every series except Enterprise, when a character is shown to be unwilling or scared to used the transporters, they are treated as eccentric and unreasonable in their fear of the device (because by the time of the original series, transporters had been in use for around a century, making it like what elevator phobia would be in the present day).
- In the main Star Trek universe, none of these effects are reproducible when you might actually want them. A gizmo that can turn an old man into a child, with his memory intact?
- In Deep Space Nine the characters of the Mirror Universe have created technology to allow transport between the two universes at will, but even they only use it once.
- A spy who'd spent many years posing as an ambassador used an apparently fatal transporter accident to fake their own death. Only detailed analysis of the... remains revealed the deception.
- MythBusters played the Star Trek transporter accidents above for laughs, by having Tory "teleported" with some of his clothes missing. (This was done during testing for a myth originating from the Star Trek episode "Arena".)
Tory: Gosh dang it! That's the third time this week!
Grant: He needs to get a new service provider.
- In Stargate SG-1, O'Neil and Carter enter the Stargate to return to base, but end up on an ice planet instead. However, it turns out they did make it back to Earth, only they rematerialized in Antarctica by coming through Earth's original Stargate, which had been lost.
- In another episode, the whole SG-1 team ends up traveling back in time due to the wormhole crossing a solar flare. In this case, due to a time loop, Hammond knew what was going to happen. Unlike other examples, this is reproducible, and the solar flare method makes up the majority of time travel in the various shows of the Stargate-verse.
- Teal'c also ended up spending a few days as data trapped in the gate's teleport buffer after the other gate was destroyed during transit, forcing the SGC to shut down gate operations (to avoid overwriting him) until they got him out.
- The technobabble explanation is that the gate sends objects as energy through the wormhole, reintegrating them on the other side. The buffer keeps that information for a short instant before the gate re-forms and expels the travelers it just received. It's also the reason iris stops reintegration with a Portal Slam.
- A thorough explanation was given on-screen in Stargate: Atlantis when a ship gets jammed in the middle of a stargate: as a safety feature, the stargate only dematerializes whole objects that pass through its threshold, then transmits them through a wormhole as energy to another stargate. If it dematerialized objects the instant they crossed a certain threshold the front half of your face would disintegrate while the back half of your body bled out. Thus an additional safety feature is that if you only stick part of an object through the stargate it will act like a doorjam, forcing the stargate to stay on - Jack did this once by sticking his gun into the portal to make sure it stayed open. Yanking out the power supply from the stargate, however, will immediately shut it down, safety features notwithstanding, resulting in a Portal Cut.
- Dialing without a proper "Dial Home Device" (the interface created by the gate builders) has caused its share of problem, such as a wormhole dropping materials in a star it was intersecting, causing it to go haywire and potentially supernova and thus potentially dooming the system's population of Space Amish (A normal DHD has safeguards to prevent this). Fortunately this one is reproduced as well, and allows them to solve the issue (or provide enough of a distraction to allow the Asgard to save it for them).
- A ring transporter near a dialing supergate and its singularity will send the matter stream to the galaxy where the supergate connects to. It's implied that the Ori made sure the matter stream would then find a ring transporter on a planet for Vala to re-integrate into.
- An energy discharge in a wormhole bisecting a black hole causes all subsequent wormholes bisecting the black hole from the same direction (in any alternate universe to boot) to connect to a specific alternate universe's stargate on Earth.
- In Fringe the teleporter has rather horrible side-effects: you have to stay in a decompression chamber for a few weeks, and even then it slowly kills you. Then again, you become Immune to Bullets.
- The Doctor Who two-parter episode "Silence in the Library"/"Forest of the Dead" featured Teleporter Accidents on a planet-wide scale, used deliberately like a lifeboat. The main computer of the Library teleported everybody into her database in order to save them from evil shadowy pirahna particles.
- The Comic Strip Presents: "The Yob" parodies The Fly (1986) remake by having a scientist accidentally merged with a soccer hooligan. Also, at the end of the episode, a macho stud ends up with the lower body of a tomcat.
- An episode of Earth: Final Conflict has a human scientist develop a teleporter (something even the Taelons haven't thought of, although they do have alternate means of travel). He uses it to assassinate some prominent Taelons with teleported bombs. The feds search his warehouse but don't find anything. Later, when found by them, he teleports himself to his warehouse, but gets "merged" with a shelf that the feds moved when they were searching the place. Just as the feds are moving in on the warehouse, he sets the device to teleport to its own location, which will somehow cause a matter/antimatter reaction.
- In Battlestar Galactica (2003), the faster-than-light drives are basically ship-wide self-teleporters, complete with some very bad things that can happen if your coordinates aren't exactly right. Jumping from too close to another ship can tear both vessels apart, a slight error when jumping in close to a planet or asteroid can leave you embedded inside a mountain, and a long range jump with questionable coordinates can leave you lost without any reference points at best—or kill you instantly thanks to the above-mentioned mountain issue. All of these things end up being done over the series, usually out of sheer desperation.
- In American Horror Story: Coven the young witches are being tested on their ability to teleport and they decide to play a game of teleporter tag. One of them does not have as much control over her abilities as she assumed and ends up teleporting herself right onto a steel fence, which is quite fatal.
- In one episode of Mighty Morphin' Power Rangers, Lord Zedd created the latest Monster of the Week from a taxi cab while Kimberly, Bulk, and Skull were inside it, resulting in the "Crabby Cabbie", as it was called, joyriding through Angel Grove with them trapped inside it. Alpha 5 eventually deduced that the only way to rescue them safely would be to teleport them out, but because he had never done something like this, warned that a mishap might happen. (He didn't go into detail; fortunately, there were no problems.)
- In the Pixelface episode, "Body Swap", an accident involving the transporter and a plasma ball results in Aethelwynne and Sgt. Riley experiencing a "Freaky Friday" Flip.
- In the 70's British sitcom Come Back Mrs. Noah, the characters decide to try an experimental teleporter to escape the space station they're trapped on. Fortunately they test it first by sending down a robot Mrs. Noah, whilst simultaneously sending up a parrot and a cat, resulting in the inevitable parrot-cat creature (maybe the cat tried to eat the bird mid-transport?) It's not clear what happens to the robot.
- Quark suffers a mild (but probably more realistic) version when he beams down to a planet and ends up knee-deep in a swamp.
- SCP Foundation. SCP-761 ("Slightly Less Dangerous Trampoline"). When someone jumps on the trampoline they are subjected to Teleportation Misfire 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 Tele-Frag.
- In Dungeons & Dragons, regular teleports don't always take you to the exactly where you want to go. Possibly resulting in being in hostile territory. Also if you roll "mishap" you take damage.
- The original version of the spell was worse. The less familiar you were of the area you were teleporting too, the more of a chance of a mishap. A mishap could either be an "Off Target" result (the most likely, where you'd appear on ground level, but not in the right place), a "Too High" result. (you'd appear in mid-air; just how high depended on the severity of the mishap), or "Too Low" (the least likely, in which case you'd probably be killed unless there wasn't solid space in the area below the target area where you ended up). A stronger variant of the spell, called Teleport Without Error, had no chance of a mishap unless you tried to teleport to another world or dimension.
- Warhammer 40,000 has a "deepstrike mishap" table, used when deepstriking (sometimes teleportation, but also includes tunnelling and being dropped from the skies). Since it's a mishap table, a lot of things go wrong. Some examples listed in the book includes units being fused to rocks (teleporting into impassable terrain). The newer edition is a bit more forgiving, but given the mechanics, it's anything but reliable.
- Warp Spiders can make a special teleportation "shunt" move during their assault phases. However things can go wrong, in which one member of the squad is dragged into the warp, never to be heard from again. This is especially scary for Autarchs, as (being a unit of one) only he can disappear, so it's recommended to keep him in a unit of warp spiders so that someone else can take the unfortunate fall.
- In Mortasheen, invoking this trope is how both Sectilians (humans with some body parts swapped with an arthropod, plus that arthropod) and Arthropoids (more complete fusions, approximating an arthropod using human biology) are formed. The difference between the two is even noted to be like that between the original version of the Fly and the remake.
- In Star Munchkin the Teleporter Accident trap makes you swap gender with one other player and swap race with another.
- A teleporter accident with Lucca's latest invention is what starts off the adventure in Chrono Trigger, opening a portal to the same spot 400 years in the past. A relatively mild example, as Lucca is soon able to figure out what went wrong and reproduce the effects in order to travel back and forth between time periods at will. It later turns out that the portals are semi-natural phenomena (depending on which writer, Contested Sequel, or wacky fan theory you subscribe to) and the teleporter (and pendant that caused it to malfunction) was only a catalyst. The fact that she just happened to set up her teleporter experiment right on top of an invisible thin spot in space-time is apparently just a wacky coincidence... maybe.
- in Final Fantasy XIV, Y'shtola uses a forbidden teleportation spell, Flow, to escape from Ul'dah after the Scions are framed for an assassination attempt on the Sultana. The reasons it's forbidden become evident, as the three characters caught up in the teleport suffer severe consequences. Y'shtola herself is trapped in the Lifestream and, when recovered, is now blind and must use a life-draining technique to see aetherically. Thancred is prematurely aged and loses the ability to manipulate aether (i.e. to perform magic). The most severely affected is Minfilia, who was trapped in the Lifestream, apparently permanently, to serve as a human avatar for Hydaelyn the Mothercrystal - this last, at least, being an intended effect, as Hydaelyn is weakened and has been having trouble communicating with her chosen otherwise.
- In Marathon, Durandal has trouble teleporting you while you are in the alien ship. Before that, Durandal, the rampant AI, captures the player mid-teleportation, and forces him to "Play a game" of killing the pfhor in a quarantine storage (leading to the level "Blaspheme Quarantine"), in which if the player loses, "(He and Durandal) will continue the relationship on friendlier terms," but if he loses, he dies. Later, Durandal has trouble teleporting you while you are in the alien ship. Tycho also steals the player from Durandal mid-teleportation a few times in Marathon: Infinity and once in Marathon 2: Durandal.
- Doom has teleporters that use hell as a stop over. Hilarity Ensues. It's also the game that introduced the Tele-Frag.
- In Pokémon Red and Blue (and their remakes), Bill accidentally combines himself with a Pokémon and the player has to help him become human again.
- The Half-Life series has a number of teleporter incidents:
Dr. Kleiner: Fascinating. We seem to have developed a very slow teleport!
- The resonance cascade scenario that triggers the events of Half-Life resulted in aliens from the Xen border world teleporting into the Black Mesa complex, leading to a series of catastrophic events that would later be cheerily known as "The Black Mesa Incident". The crystal that caused the cascade was retrieved from Xen, which itself was discovered as a result of the earlier teleportation research by Black Mesa.
- One of the later puzzles of the first game involves navigating a complicated array of teleportation portals; jumping through the wrong portal at the wrong time will often result in Freeman falling to his death. Also, one of said teleporters is visibly malfunctioning and will kill you if you enter it.
- In the Opposing Force expansion, one of the weapons is the Displacer, a hand-held portal generator. The primary fire fires a highly unstable portal that can be used to damage enemies due to its effects on nearby objects and space-time, while the secondary fire teleports the user to a semi-random location. Shepard first picks up the weapon from the body of a scientist who had teleported to thin air at high altitude. If Shepard uses the secondary fire in the wrong place, the same can happen to him.
- In the second expansion Blue Shift, Calhoun suffered a temporary resonance displacement, which could have resulted in an infinite harmonic reflux (according to Rosenburg) while teleporting to safety at the end of the game.
- Early in Half-Life 2 the rebels try to teleport Alyx and Freeman to Black Mesa East. Mention is made of a teleportation incident with a cat that Calhoun apparently still has nightmares about, which doesn't reassure Alyx at all. Alyx is teleported successfully, but when Freeman is teleported, Lamarr interferes and he ends up randomly appearing in various locations before finally materializing just outside the lab he started at.
- Also possibly a sly reference to Schrödinger's Cat.
- In the same scene, there's a mini-teleporter in the corner of the lab. Activate it enough times and it will short out, earning you the achievement "What Cat?"
- While it isn't shown, in the same incident another potential example of this trope is mentioned when Barney tries to free Gordon - Kleiner shouts in response "You can't just wade into the field; it will peel you apart!"
- Later in the game, when teleporting out of Nova Prospekt, the teleporter explodes while Alyx and Freeman are in mid-teleport, resulting in them being caught in a week-long teleport loop. As a result, by the time they emerge the revolution is in full swing.
- The Borealis was an Aperture Science Research Vessel that suddenly completely disappeared from the shipyard, taking a chunk of the drydock with it. 20 years later, it is discovered by a team of Rebel scientists in the Arctic.
- In Combat Evolved, Cortana accidentally drops John-117 on his head. Thankfully, it was only a few inches; he was on target, but arrived upside down (Cortana was working out the alien coordinate system and got plus mixed up with minus).
Cortana: Oh, now I get it: the coordinates need to be— (John smacks the side of his helmet, and Cortana continues in a sheepish tone) Right. Sorry...
- In Forge mode from Halo 3 and onwards, players can put teleporters wherever they wish. Naturally, this includes setting them up so that anyone using the teleporter will fall to their death.
- In Combat Evolved, Cortana accidentally drops John-117 on his head. Thankfully, it was only a few inches; he was on target, but arrived upside down (Cortana was working out the alien coordinate system and got plus mixed up with minus).
- The developers of Portal and its sequel wanted the player to feel safe using the portals, so if you close a portal you're standing innote , you'll simply be pushed rather than cut. However, under some circumstances, it's possible to die or get stuck in the wall if you do this.
- In Space Quest V, a transporter accident swaps your head with the head of a fly, in a Shout-Out / blatant rip-off of The Fly.
- At one point, Roger's head is turned into a giant eyeball and at another, he was partially melted. (These were just sight gags and were fixed immediately afterwards)
- Eventually, the characters figure out that they can use the teleporter to intentionally create an accident and thereby separate the toxic goo from the people it's infected.
- It's also mentioned that, originally, Cliffy installed a voice-control system for the teleporter and set it to the sound of a clap. This got ugly when a visiting dignitary got on the platform and applauded the crew... while in deep space. Cliffy had it changed to react to "Energize" instead.
- In the first Wild ARMs game, a teleporter accident will send you to The Abyss. Oops.
- World of Warcraft has craftable teleporters which can send you to certain cities. They're stated to be safe and reliable, except they aren't, having possible mishaps such as making you an evil twin, changing your appearance to that of another race or sending you high, high up in the sky. In the case of the latter, it's a good thing the engineers capable of making these devices also have the option of adding a parachute to their cloaks.
- If you forget to eat your peanuts in the brutally unforgiving Infocom game of The Hitchhiker's Guide to the Galaxy, being teleported off the Earth winds up killing you. Since the text directing mentions this, it was probably the easiest puzzle in the game to solve.
- The Suikoden series has the recurring character Viki, a young sorceress with very powerful teleportation magic. Unfortunately, she's also an error-prone ditz who occasionally botches a teleport. In gameplay, her errors are completely harmless: a time-consuming annoyance at worst, and sometimes actually helpful since they're the only way into certain rooms that are locked from the inside. Story-wise, more serious accidents (one at the end of each game) explain why she's able to appear in every game of the series despite her being a teenager in all of them and the games having gaps of as much as 150 years between them: when she really botches a teleport, it's not just a matter of where she'll end up but when.
- If you use her teleport rune in battle, she will teleport things (enemies out of the battle, or heavy objects that will fall on the enemies). If she botches a teleport at this time, it can have disastrous results (such as teleporting all allies except her out of battle, or making the heavy object fall on the party).
- Sid Meier’s Alpha Centauri: Upon discovering Matter Transmission, the quote from Professor Zakharov is: "The first living thing to go through the device was a small white rat. I still have him, in fact. As you can see, the damage was not so great as they say."
- The Bulk Matter Transmitter secret project cutscene shows a spacecraft entering the transmitter and reappearing at an identical one far away... but as an outline of light that then drifts away. This is followed by a quote from Sister Miriam Godwinson (a religious fanatic) asking if the human soul makes it through the transmission.
- The Chronosphere teleportation system from the Command & Conquer: Red Alert series (see above) is lethal to unprotected human passengers, although this is somewhat inconsistently applied. In the first game, teleporting an APC full of soldiers results in the APC arriving at its destination empty, implying the soldiers were all killed...so what about the driver of the APC or any of the other vehicles that can be teleported? Makes more sense in the second game, where the Chronosphere only kills infantry out in the open (and indeed can be used as a weapon directly against the enemy in such a way).
- You can also use it to sink enemy tanks or put enemy ships on land. Not very effective in Red Alert 3, where many tanks are amphibious and some ships are able to walk on land.
- It's also inconsistent with the opening cutscene, in which Einstein uses it to travel back in time and kill Hitler. Then again, that chronosphere was built in another timeline by an Einstein with different priorities... but then a cutscene in the Soviet campaign has the Allies rescue Einstein from a (fake) firing squad by chronoshifting him alone.
- In the Unreal Tournament series, the Translocator sends a beacon and the player then teleports to the location where it landed. Should that location happen to contain another player, this will result in violent death, for them. The beacon can be damaged if an enemy shoots it, at which point attempting to teleport, or calling back the beacon, will result in violent death, for you.
- The prologue to Saira involves one of these, where the main character seems to have been accidentally teleported into the distant future (or another dimension, or something). Her apparent boyfriend was a mis-teleport victim, too; he was hurled to the other side of the galaxy by mistake, and the plot of the game revolves around Saira trying to teleport herself there. Most of the endings are also teleporter accidents; she gets sent to the wrong place if the teleport parts used aren't fancy enough, but somehow she always ends up somewhere habitable.
- The Game Of The Ages: Until you learn to protect yourself, portal pools rip you apart.
- A recurring mission hook in LEGO Rock Raiders is that the teleporter aboard the LMS Explorer is malfunctioning due to power problems, resulting in various things being beamed into the wrong cavern and Chief sending you to retrieve them.
- Averted in Nethack, otherwise random teleports would be too dangerous. And are a number of ways the player can be teleported by accident or incident. Any teleport will result in a destination square that's not open water, not in solid rock, not on a trap and not occupied by other monster. It may be possible to overcome this fail-safe by filling all safe squares with monsters, and randomly teleporting from an unsafe square. (By levitating over water or polying into a Xorn that can phase through rock.)
- Played straight for some cases of controlled levelporting, the ability to teleport between levels. Basically you input a number corresponding to the level you want to teleport to. Teleporting too deep of a level has little consequence, as the game will simply teleport you to the lowest level of the current branch. Teleporting to a zero or negative level, however...
- Downplayed in Devil Survivor 2. When you first use the teleporter, it is poorly calibrated. Fortunately, instead of something horrible happening like missing half your body, you only teleport high above the floor, and you end up with Makoto landing butt first on your face. This scene also is a Subversion because Fumi expected you to end up with missing body parts, but apart from the fall you were unharmed.
- A brief one is featured in Shin Megami Tensei III: Nocturne, as a result of operating eldritch technology. Luckily, only a brief detour comes from it.
- In fact, the entire series got kicked off when in Shin Megami Tensei I an improperly calibrated teleporter dragged a demon into the material world.
- The plot point for Teleglitch, when all hell breaks loose inside a weapons testing facility after the succesful transporting of a single molecule from an alternate universe. Who thought murderous AIs could fit inside a single molecule?
- An adventure in Kingdom of Loathing has some Space Tours fan ghosts getting in a teleporter, which is then ruined by your character sneezing. The end result is a fusion of all of the ghosts, which mutters "Ges... und... heit" before offing itself.
- Terraria plays this straight with the Rod of Discord, which is used to teleport over distances. If the item is re-used during its cooldown period, it will cause heavy damage to the user. The game lampshades this if the teleport damage is fatal, mentioning that the player failed to rematerialize or now has feet where their head used to be.
- In Warframe, the original Limbo was killed when trying to enter the Rift, an alternate plane of reality. The Tenno can find pieces of him scattered through the Origin System, and creates a copy of Limbo's Warframe to honor him.
- Invoked to the characters advantage in the second installment of the Deponia series, Chaos on Deponia. Three teleporters are set up, but in each there is an animal (platypus, flog, fly) that cannot be moved. Teleportingb away will merge Rufus, teleporting back will split him back up - unless the target teleporter cell also is occupied, in which case exchanges happen. You have to set everthing up so that Rufus appears on the far side without merge.
- Averted in Worms, where you cannot teleport your worm to a place occupied by other or into solid space. However you can send it very high in the sky and since falling from excessive heights causes damage to a worm, it has creative uses it said worm has very few life points remaining.
- In The Order of the Stick a drunk wizard teleported the party into a wrong place. On the bonus side, he was so drunk that eating him knocked out that Roc.
- In Wapsi Square, Monica is capable of teleporting, but isn't particularly good at it. As a result, she tends to suffer comical but harmless mishaps such as poor arrival placement, upside down on arrival, and switching clothing with the person traveling with her.
- The first arc of the highly NSFW comic Devious Tangents had two guys (well, sort of) coming out of a transporter as one girl
- In Accidental Centaurs, a malfunctioning teleporter prototype explodes, creating a wormhole to another dimension that sucks up two of the system's designers. On the other end of the wormhole, they find that they have been transformed into centaurs.
- Red Space Blues: this unfortunate goat, even before that the teleporter had a bad habit of duplicating a person and then exploding the original.
- Played for laughs in Commander Kitty. CK's bargain bin transporter isn't guaranteed to get you to your destination in one piece.
- This is called 'dirty warping' in Our Little Adventure. Merla hastily psionically teleported herself, Lenny, and Julie away from a hostile that was about to attack them. Not only were they off the intended target area when they arrived, but they got some severe nausea and minor injuries.
- Chakona Space gives us Dale Perkins: male human. The transporter on the orbiting space station is sabotaged in the middle of his transport, and his pattern is lost. Goldfur (Furry herm Chakat) thinks fast and shoves a cart filled with luggage, imported fruits and veggies, and other assorted knick-knacks onto the transporter pad to make up for the missing mass and tells the operator to simply use hir pattern, which hasn't been overwritten yet. Goldfur gains a new twin◊ and Dale survives the experience and learns to live as a Chakat.
- In Potter Puppet Pals, Ron trying to Apparate with Harry turns the two of them into basically a puppet version of The Human Centipede. An attempt to separate themselves by apparating again only results in Snape also fusing with them.
- During episode 8 of Freeman's Mind, Freeman wonders out loud after killing some headcrabs he encounters crawling around in the ceiling ducts:
Freeman: What are aliens doing up here, anyway? I guess they must have teleported in, but how do they know where to go? Oh, maybe they don't. Maybe they're teleporting into the walls. That could be why the building's falling apart. We're turning into the Swiss Cheese of the Damned!
- In one episode of The Venture Bros., Dr. Venture ends up (harmlessly) stuck in the walls of various parts of the house, in three pieces, for the duration of the story. To quote him, "Well, wherever my lower half is, it must be outdoors. I think it's raining."
- In X-Men: Evolution, Forge tries to extend the range of Nightcrawler's teleportation, and ends up creating rifts to the hell-like dimension Nightcrawler uses to move from place to place. Needless to say, the inhabitants get out.
- ReBoot has a Shout-Out to this in one episode. Bob tries to use a makeshift transporter (itself a Shout-Out to Star Trek) to separate himself from Glitch. Bob dematerializes and then rematerializes with no change and somehow picked up a passenger along the way. Then the trope is played straight later when Bob tries to use a portal for the same purpose, only for it to explode and nearly kill him.
- SpongeBob SquarePants and Squidward got fused this way (and at the end, with others as well).
- Dexter's Laboratory episode "Sole Brother" featured Dexter testing a teleporter. When he used it on himself, he ended up fused with Dee Dee's foot.
- When Candace and Perry fell into Phineas and Ferb's teleporter in "Does This Duckbill Make Me Look Fat?", they swapped bodies.
- When the boys build another teleporter in "Picture This", this one based on transporting things in pictures, several accidents occur before Phineas and Ferb get the hang of the machine; Buford winds up a human/fly hybrid before Phineas installs a "fly filter", and transporting Ferb's skateboard from England brings Grandpa Fletcher's feet along with it. (They return the feet, but now they're backwards. "Now I can finally see where I've been!")
- The Pink Panther once fused the pale guy with a flower and himself to a bee.
- An episode of Family Guy opens with a parody of The Fly where Stewie merges with Rupert while testing his teleporter. He's back to normal after the opening.
- This happens to poor Odd twice in two episodes of Code Lyoko:
- The first time, he tries to bring his dog Kiwi to Lyoko with him, but the scanner somehow merges the two of them together. Suffice to say, this caused a lot of problems.
- Even worse was the time Jeremie tried giving Odd's Lyoko form the power to teleport. When he returned to Earth, there were three of him. (And they all didn't like each other.) Jeremie was able to fix the scanner to reverse it, but first Odd had to find his other selves who had wandered off, and XANA wasn't making it easy for him, his latest attack being a smog that could turn people to stone.
- Averted in the My Little Pony: Friendship Is Magic episode "Twilight's Kingdom - Part 2", but it comes close; Twilight's Power Incontinence teleports her all over Equestria, and despite the distances involved, she only ends up stuck between two rocks on the last jump. This is also the first time she uses the word "teleportation" to refer to this ability.
- Most of the space bridges in Transformers: Robots in Disguise are built by amateurs with substandard materials. As a result, they tend to fail more often than not, sending users to the wrong location (the arctic, an erupting volcano, etc.) One jury-rigged Spacebridge produced a black hole that nearly destroyed the planet.
- The plot of the Regular Show episode "Mordeby & Rigbecai"; Mordecai and Rigby using a teleporter results in Mordecai getting Rigby's torso and arms, while Rigby becomes taller and with Mordecai's arms. Mordecai is less than enthusiastic about his reduced height.
- The Philadelphia Experiment was supposedly a US Navy-sponsored attempt to develop an Invisibility Cloak for a destroyer escort. The story goes that the ship successfully vanished for a period of time, then returned with some of its crewmen stuck through the bulkheads.
