[[TeleportersAndTransporters Teleportation]] can be very dangerous if you don't look where you're going. If you teleport into someone else, or someone else teleports into you... [[LudicrousGibs splat.]]

The term comes from early FirstPersonShooter VideoGames, where both materializing when spawning and proper teleportation can "frag" a player standing in the wrong place at the wrong time. This is because two nested hitboxes would have meant that the 2 players were going to be stuck in place. The developers then came up with a clever fix.

This is also known as interpenetration, especially when there is no exploding involved.

In the cases where this is harmful to the teleporter, [[TheAirNotThere the dangers of teleporting into a space currently occupied by air and dust are usually ignored]]. This can be {{handwave}}d by stating that the teleporter is capable of displacing gases, liquids, and minuscule solids therein, or by the fact that compared to about every other substance humans normally deal with, air is very thin stuff.

The usual {{aver|tedTrope}}sion is swap-porting. Then, if you appear inside a mountain, a statue appears at the starting position, but you're still BuriedAlive unless you can teleport again immediately (bearing in mind that encasing [[AndIMustScream tends to impair]] ability to [[MagicalIncantation speak]], [[MagicalGesture move]], or indeed [[FreakOut think clearly]].) In this case, any living being who is teleported ''into'' will be horribly eviscerated, while the one doing the teleporting may be merely [[MyGodWhatHaveIDone psychologically traumatized]].

The opposite of a PortalCut (a perfect guillotine made by disconnection of the gate's surfaces while someone or something is passing through, or otherwise using partial teleportation to cut something apart). If the teleporter isn't fine tuned, expect a TeleporterAccident to result.

See also PortalSlam (when there's something in the way when you try to ''enter'' a teleportal). Can be used to defy InertiaIsACruelMistress by destroying the offending obstacle, or as WeaponizedTeleportation. The supertrope is teleporting things to anyplace that's inherently extremely dangerous even if it's not actually inside a solid object, such as into deep space, over lava, or 100 feet straight up.



* Occurs [[MoodWhiplash suddenly and horrifically]] in [[http://www.youtube.com/watch?v=4Am7oKBD3PU an ad for the Australian Central Institute of Technology.]]

[[folder:Anime & Manga]]
* ''Manga/MahouSenseiNegima'': the cast had just traveled a ten-day leap backwards in time to SetRightWhatOnceWentWrong, unfortunately without enough time to give any idea as to ''where'' they would appear. They nearly fell several thousand feet, but afterward one character remarked about their luck of not appearing inside a rock.
* In ''Anime/DarkerThanBlack'' one of Contractors has swap-teleport power, so even [[http://static.tvtropes.org/pmwiki/pub/images/black1st03.jpg arriving mostly inside a stone wall]] wasn't any trouble for him. It was more dangerous for people [[PortalCut whose vitals he tried to swap with some part of said wall]].
* Hashigen Uchida from ''Manga/{{Bleach}}'' uses this to take out [[spoiler:Barragan]] by making his own powers work against himself.
* ''LightNovel/ACertainMagicalIndex'': Awaki is a Level 4 Teleporter like Kuroko, and was on her way to becoming Level 5, but she had an incident where she miscalculated her teleportation and ended up getting her leg [[TeleFrag telefragged]] into a wall, panicked, and ended up tearing a large amount of skin and muscle off. Her leg has since been healed, but the trauma was so terrible that she is paranoid about teleporting herself and takes an extra 3 seconds to recalculate, and anything that reminds her of the incident terrifies her. The stress when she actually does manage to teleport makes her unable to do it consecutively more than 3 or 4 times and makes her vomit.
** Telefragging is one method fans have thought up to get around [[StoryBreakerPower Accelerator's "I'm invincible" powers]], but the author accounted for this as well: teleporting involves 11th dimensional movement, so there is still a ''vector'' of movement with teleportation, meaning Accelerator would just reverse the teleportation like he does everything else.
* ''Manga/ACertainScientificRailgun'': Kuroko explicitly states her teleporting one object into another displaces the material occupying the old space, regardless of what either object was. At one point, she tears down ''a building'' by teleporting sheets of glass into its support pillars. She also threatens to teleport her needles into people. She only tries this once, however, and it misses (the target was an illusion that she fell for).
* ''VisualNovel/SteinsGate'': Some of the experiments of SERN got stuck in various places due to the Earth moving, meaning time-travel is pseudo-teleportation if no coordinates are set.
* The [[AbsurdlySharpBlade Dimension Sword]] technique in ''Manga/RosarioToVampire'' is a combination of Telefrag and {{Vibroweapon}}. By shifting dimensions, a user can pass through objects unchallenged - and by shifting back, they will promptly ''destroy'' whatever they are currently within - from a block of wood to a suit of armour to human flesh. The most efficient form is doing this 'shift away, shift back' action ''one hundred times per second''[[note]]Ling-Ling Huang uses a less practiced form of sixteen shifts per second, and promptly gets her ass kicked against a user of the 100 s/s version[[/note]].

[[folder:Comic Books]]
* ''ComicBook/{{Watchmen}}'' took this to the logical extreme with teleporting into ''air'' being deadly.
* ''ComicBook/{{X-Men}}''
** Marvel's most famous teleporter, Nightcrawler, in the ComicBook/AgeOfApocalypse is shown once teleporting away from an enemy -- taking several of the foe's ''fingers'' with him. He does it again later, [[spoiler:with Dead Man Wade's ''head''.]]
** The Regular continuity Nightcrawler has ''threatened'' this on several occasions, scaring opponents into submission by telling them he'll teleport their arms off. In practice all he really ever goes is grab someone and 'port them a few times until they pass out, as teleporting is depicted as [[TeleportationSickness extremely uncomfortable]] for those not used to it.
** Rogue, using Nightcrawler's power, teleported Nimrod's arm off the first time the X-Men encountered him. (Nimrod being a robot gets around the heroes-don't-kill thing.) Nightcrawler tried to do the same thing later on, and Nimrod demonstrates why [[AdaptiveAbility using the same tactic against him twice is a bad idea]].
** Nightcrawler gives his fear of telefragging as reasoning not to teleport into a place that he hasn't seen, and in some versions that isn't within sight of his location.
** [[spoiler:Nightcrawler ''willingly'' telefrags himself by teleporting in the way of Bastion's blow against Hope and gets an ''arm'' stuck in his chest for his efforts. He teleports Hope away, taking Bastion's arm with him, and clings to life just long enough to make sure that Hope is safe with Cyclops before dying.]]
** In Creator/KevinSmith's ''Spider-Man & Black Cat: The Evil that Men Do'', Nightcrawler remarks on the effects of killing someone by teleporting into their body. He avoids the act based on the squick factor, and because he [[TechnicalPacifist doesn't kill people]]. The villain of the piece, Francis Klum, performs this on his brother to prevent him from raping Black Cat.
* In ''ComicBook/{{Exiles}}'', team teleporter Blink has done this, both intentionally and [[MindRape while under someone else's control]]. While fighting [[BigBad Hyperion]], Blink fakes a redirect portal to distract him, then uses her power to [[TeleFrag fill him with sand.]] Due to one of his [[HealingFactor abilities]], it didn't last very long. Fortunately, [[spoiler:in the end Hyperion is sent back to his own reality. The reality where he had [[AGodAmI caused the deaths of everyone else on the planet]], [[AndIMustScream leaving him the only person left on Earth.]]]]
* This happened to ComicBook/CableAndDeadpool in their eponymous comic, Cable accidentally teleporting into Deadpool and [[TwoBeingsOneBody fusing the two of them together]].
* ''ComicBook/TopTen''
** Travelers are killed when two vehicles fuse together like this. It's treated like a traffic accident.
** Wolfspider lost his legs in such an accident. He takes a ''personal'' interest when some jerk causes such a crash. [[GroinAttack Very personal]].
* In Creator/AlanMoore's seminal ''ComicBook/{{Miracleman}}'', one of the first moves in the climactic fight against Kid Miracleman is to teleport him into a wall. It doesn't work at all; he breaks out instantly. [[spoiler:It does, however, work when the Warpsmith tries it the other way around -- teleporting a chunk of asphalt and rebar into Kid Miracleman's head, and an I-beam through his chest. Even this isn't immediately fatal.]]
* Creator/DonRosa points out that it can also happen with [[http://disneycomics.free.fr/Ducks/Rosa/show.php?num=3&loc=D950792 time travel]]: what if, in the age you're travelling to, there's a tree right where you stand? It's what sets in motion the plot of ''The Once and Future Duck''.
* In ''ComicBook/TheSavageDragon'', the time-travelling villain Darklord was originally dispatched this way. After beating several heroes near to death, he leapt through a teleporter in order to get to Earth. What he did not count on was that the teleporter had previously been given a virus and was in the process of shutting down. Half of him arrived on Earth but the other didn't. Keep in mind, since Darklord was a time-traveler, this didn't really stop him from showing up again.
* In the ''ComicBook/TerrorTitans'' miniseries, Dreadbolt induces this in his father, Bolt, by interfacing with his suit and forcing him to teleport halfway into a brick wall, killing him.
* In the 2014 relaunch of ''ComicBook/PaperinikNewAdventures'', the Raider, after showing the ability to use his [[TimeMachine chronosail]] for [[TransportersAndTeleporters teleportation]], [[spoiler: moves a gigantic planet-moving engine inside a slightly smaller Evronian space station, blowing up both]].

[[folder:Comic Strips]]
* In a Virgin Comics ''ComicStrip/DanDare'' issue, a team of commandos is poised to rescue Dare from the Mekon's battleship via jumping by dead reckoning directly into the landing bay. It's a risky move no matter how confident they are in the maths. When they arrive, they have the top halves of some very surprised enemy troopers sticking out of the deck into their ship. Their intrepid pilot was less lucky; the nose of the ship, and part of his head, were embedded into a parked shuttle.
* In [[http://dilbert.com/strips/comic/2006-05-07/ a Sunday strip]] of ''ComicStrip/{{Dilbert}}'', a future version of Wally, conducting some highly unethical time travel, accidentally telefrags a past co-worker when attempting to get a fresh cup of coffee from the past.

[[folder:Fan Works]]
* [[DiscussedTrope Discussed]] at one point in ''WebVideo/MyLittlePonyTheMentallyAdvancedSeries''.
-->'''Applejack:''' Aren't y'all worried about teleporting inside somepony?
* In ''FanFic/TheStarsWillAidTheirEscape'', Twilight, Shining Armor, and the remaining Royal Guards deliberately invoke this in order to eliminate the [[EldritchAbomination Dark]] [[{{Mooks}} Young]].

[[folder:Films -- Live-Action]]
* In the end of the remake of ''Film/TheFly'', this seems to be the result of teleporting someone with an inanimate object: [[spoiler:Brundle is fused with pieces of the telepod itself, and the pieces semi-randomly fill up his body.]]
* In the ''Franchise/{{Terminator}}'' canon, time travel destroys everything in its path, [[SphereOfDestruction leaving a spherical hole]] [[PortalCut around the point where the time traveler arrives]]. In the original script, however, Reese was sent back with another soldier, who was killed on arrival when he materialized halfway through some of the scenery.
* In ''Film/DungeonsAndDragonsWrathOfTheDragonGod'' (the infinitely better sequel to the original ''Film/DungeonsAndDragons'' movie), teleportation requires being able to accurately visualize the target location, lest this trope occur. The heroes thus search out a scrying mirror that shows images of places the user has never been. The inventor, however, as a cruel joke didn't make it perfect, so the images have a chance of being slightly off. The mortal he gave it to ended up in a wall. The mage on the team gets it somewhat better: her team is fine, but her arm is in a wall, which they then must lop off to teleport again..
* ''Film/ThePhiladelphiaExperiment'' has sailors fused into the deck of the ship during the title experiment.
* ''Film/{{X-Men}}''
** In ''Film/X2XMenUnited'', Nightcrawler cites this as the reason he refuses to teleport anywhere he can't see.
** In ''Film/XMenOriginsWolverine'', John Wraith uses his ability to dodge Victor Creed's claw attacks, until Creed uses his knowledge of Wraith's fighting style to lead him, stabbing right where he knew John would end up. Worse than stabbing: Creed knew Wraith so well, he was able to [[BodyHorror grab hold of his spinal column,]] [[NightmareFuel and rip it out when Wraith tried to 'port again.]]
** Azazel uses the "100 feet up" variant quite a bit in ''Film/XMenFirstClass''.
* The original ''Film/{{Stargate}}'' film: There's a deleted scene where it is shown two Horus Guards apparently tried to come through the gate while it was buried. This left them ''flash-fossilised'' in solid rock.
* {{Defied}} by Doc in the third ''Film/BackToTheFuture'' film. He explains the reason they're out in the middle of the desert is because the De Lorean will have plenty of run-off space in a wide-open area. Sending Marty back to a place that is populated or geographically unknown would be ''very'' dangerous idea; there's a risk he could easily [[PortalSplat crash into]] someone or something that once existed there. Doc doesn't clarify if this also extends to materialising ''inside'' something that once existed as well, but the implication is that it would be just as much of a danger.

* Mentioned as a concern in the ''Franchise/{{Halo}}'' novel ''[[Literature/HaloGhostsOfOnyx Ghosts of Onyx]]'' where two human ships had tried to engage their [[FasterThanLightTravel FTL slipspace drives]] without sufficient power and were turned into atomized pieces.
* A very mild form happens in ''Literature/ArtemisFowl: The Lost Colony'' in the time-tunnel. Artemis and Holly each wind up with one of the other one's eyes, and No1 loses a couple megabytes' worth of memories.
* One of the ''TabletopGame/MagicTheGathering'' books had a character with an item that let her teleport anywhere by intoning where she wanted to go three times (''Wizard of Oz'' style). She uses it in a way probably not intended by the person who gave it to her when she says the name of one of the villains three times. LudicrousGibs result.
* The protagonists of Creator/RobertAHeinlein's ''Literature/TheNumberOfTheBeast'' worry about what would happen should they accidentally end up inside solid rock, mainly because their best guess is that it would create an explosion the size of a small star. Thankfully they're careful (or lucky) enough that it never happens. It is also brought up in passing in ''Literature/TheDoorIntoSummer''.
* ''Literature/TheStarsMyDestination''
** In this novel by Alfred Bester, telefragging was used as an incarceration device. In the novel, every human has learned how to naturally self-teleport (called Jaunting), which made it rather difficult to detain prisoners. The method that governments used was to put the prisoners into jails which prevented them from having any knowledge of their present location (by being deep underground and in the dark, for instance). Knowing where you are, and where you're going are prerequisites for safely Jaunting. By preventing prisoners from knowing where they are, they could not Jaunt to where they'd like to be without a very large chance of ending up somewhere else entirely... like inside a mountain. Occasionally a prisoner would go insane from the isolation and attempt a "Blue Jaunt" (as in "into the wild blue..."), which was just a fancy way to commit suicide.
** This also happens in one of the jaunting hubs during a major evacuation. The effects are not dwelt upon.
* Averted in ''Literature/{{Discworld}}'', because when someone teleports, whatever was at their destination is sent back (see swap-porting above). In ''Discworld/InterestingTimes'', Rincewind points out this isn't much better:
-->'''Rincewind:''' So I'd still be in the middle of a mountain but in a me-shaped hole? Oh good, instant fossil.
:: In fact, this actually becomes a plot device later on.
* Creator/TerryPratchett also references the idea in ''Literature/JohnnyAndTheBomb'', where [[TheSmartGuy Kirsty]] points out that trying to occupy the exact same space as another object is likely to cause the atomic nuclei to fuse, with [[StuffBlowingUp interesting and deadly consequences]].
* Averted in ''Literature/TheLongEarth''; if you attempt to ''step'' to an alternate Earth, and the spot where you'd arrive is occupied by solid matter, you are just gently stopped from travelling.
* ''Literature/TheWheelOfTime''
** Traveling portals PortalCut away anything that happens to be where they open, living or inanimate. Later in the series, vertical spinning portals opening and closing rapidly are employed as weapons to slice apart enemy troops.
** Likewise, Shadowspawn can't survive a trip through the gates, so opening random portals under them is a combat technique.
* In one of the earlier ''Literature/DragonridersOfPern'' books, a party exploring some of the abandoned corridors of Benden Weyr came across a Weyrling pair (a young dragon and his equally young rider) encased in rock after a bad jump ''between''. They had no idea who they were or how long they'd been there. (We do find out who it is in ''Dragon's Blood''). A more frequent danger for the Dragonriders is simply not coming out the other side of a jump.
* In the ''Literature/HarryPotter'' universe, the Floo Network (basically magical teleport conduits) and use of Portkeys (charmed objects designed to transport the user to a designated spot) are monitored and regulated to avoid such collisions. Apparating is also restricted to adult wizards and witches for this reason, as there's a good chance that parts of the wizard or witch could fail to appear in the right places (a phenomenon known as "splinching"). This happens to Ron in ''[[Literature/HarryPotterAndTheDeathlyHallows Deathly Hallows]]'', and it's not pretty. Fortunately, wizarding medical science can treat pretty much everything other than death, curse injuries and (for some reason) eye maladies, so while messy, injuries resulting from failed apparition can generally be rectified with a minimum of fuss, assuming of course that you're ''not'' currently on the run from the BigBad.
* ''Literature/TheBelgariad''
** Relg the Ulgo once used his power of phasing through rock to kill an attacker by phasing both of them into a boulder, then phasing just himself back out, leaving two hands gruesomely protruding from the boulder.
** He also used a more conventional telefrag to create handholds in a rock wall, allowing the rest of the party to easily scale it, by phasing his hand in and out, instantly powdering the rock in fist-shaped holes.
** In Belgarath's CrowningMomentOfAwesome, [[spoiler:he repeats this trick on TheDragon, Belzedar, burying him in rock far underground. He's not dead, though.]]
* May have happened in Piers Anthony's ''Literature/{{Mode}}'' series. Darius can teleport himself and others safely to any location he's familiar with. (He names a general area, visualizes it, and the magic presumably does the rest.) When the group is attacked by two soldiers, he teleports them to their castle, which can just be seen on the horizon. When another character asks if he's ever been there, he says, "No. So their arrival may be unpleasant."
* Asimov's ''Literature/PebbleInTheSky'' features an accidental time traveller from the 20th century whose had the toe of his shoe PortalCut off by the "time travel beam". The same beam also brought half of a doll lying on the ground with him.
* In ''Literature/TheTomorrowWar'', jumping ship absorbs anything in targetted space. So it's wise to chose destination without atmosphere or excessive dust. Or too strong solar wind. And they have lots of redundant systems to survive this constant contamination. Exclusion: ships able to hang in transition state (submarine-like) exit into the normal space more slowly and somehow displace thin dust or gas. Also, volume carried by single jump drive is limited, so big ships have several, and when one of drives or their synchronisation fails, ship is PortalCut by jump.
* In the short story 'Via Vortex' of the ''Sideways in Crime'' alternate history anthology, the victorious Nazis use Pseudo-Science to teleport around the world. When you are teleported somewhere you need an equal amount of human flesh to recreate yourself. Convicted criminals supply said mass. The teleport booth has a built in shower to clean out either the original disassembled 'you', or any leftover mass from the victim you reappear within.
* The Warlock's kids from the ''Literature/WarlockOfGramarye'' series like to play by 'porting rocks inside of trees. Boom! Try it yourself, it's great fun, if you can surround yourself with [[DeflectorShields impenetrable forcefields]] to avoid splinters. And be sure to [[{{Telepathy}} telepathically scan]] the area first so no innocent bystanders get hurt. 'Kay?
* Bhelliom in Creator/DavidEddings' ''The Shining Ones'' mentions how unusual it is for two objects to share the same space. When asked about it:
-->''"I beg of thee, ask him not to continue this line of enquiry. The answers will greatly disturb him."''
* Franchise/DoctorWhoExpandedUniverse
** The ''Literature/DoctorWhoNewAdventures'' novel ''Transit'' has a teleport network spanning the Solar System, where trains are sent through the gates. There are occasional references to the Bad Accident, which is eventually explained as what happened when two trains tried to materialise in ''almost'' the same place at the same time. They ended up merged together. And so did everyone on board.
** Also referenced in the ''Literature/DoctorWhoMissingAdventures'' novel ''The Dark Path'', as a semi-standard military tactic used to cripple starships (e.g., by teleporting someone or something into the location where a ship's pilot is sitting) without actually damaging the ship itself - and yes, the technique was actually referred to as "telefragging".
* In the ''Literature/YoungWizards'' sidestories, the Feline Wizards, Arhu is arguing about the dangers inherent in the place they're going. His older partners warn against cave ins, at which points he mentions teleporting out or simply phasing through it. Irritated at him being right, they pull out an unlikely and convoluted scenario involving the Gates warping the reality of the rocks he's working on, getting him stuck inside and destroyed because the rocks are "older". His elders have been working with the Gates for years; they ''know'' that this kind of thing can happen. In fact, they've probably ''seen it''. It was a scare tactic. It's possible, but they just wanted him to shut up and listen since the arrogant attitude would cause dangers in itself.
* The Creator/StephenKing short story ''The Jaunt'' has an interesting take on this. (And yes, the title's a ShoutOut to Bester's novel.) If you're conscious while you teleport, your mind experiences an astronomical amount of time as pure consciousness, while your body is instantly transported. We're talking ''millions of years'' seeing the unseeable. Everyone who has emerged while conscious has either died instantly from shock, or gone utterly insane, and so travelers are given mandatory sedation. It's mentioned that the system has been used by the [[TheMafia Mafia]] and others as a dumping ground for victims both dead and alive, implying that there may be people existing ''eternally'' as pure consciousness. AndIMustScream, indeed.
* John Birmingham's story ''[[Literature/AxisOfTime Weapons of Choice]]'' sees a [[TimeTravel time-travelling]] naval flotilla from 2021 shoot back in time to 1942. It [[TeleFrag telefrags]] the US Carrier Strike Force en-route to do battle with the Japanese at Midway. One ship from the future "intersects" with a ship in the past. The book even mentions two fused crewmembers going into a frenzy caused by pain and shock (as well as their mismatched blood types poisoning one another) and [[MutualKill kill one another]]. They end up scuttling both ships. Another ship gets PortalCut (it was too close to the edge of the Transition), and its reactor promptly blows up.
* Creator/JamesHSchmitz's ''Literature/TelzeyAmberdon'' story "Sleep No More". Telzey is being pursued by a teleporting monster that homes in on its target's mind. She mentally projects an image of herself being inside a nearby mountain, and when the monster teleports to that location and merges with solid rock there's an explosion.
* Creator/DeanKoontz novel ''The Bad Place''. Frank Pollard has a problem: when he teleports, small pieces of nearby objects end up being permanently embedded in his body. [[spoiler: As the porting is [[PowerIncontinence somewhat uncontrollable]] and resulting in more and more outside mass being incorporated, the book ends with him forcibly teleporting his villainous brother again and again until their bodies have merged and enough outside mass has been worked in to make the final configuration unable to survive.]]
* In Michael Grant's ''Gone'', a cat teleports into a book, and the results are not pretty.
* In the novel ''Mindbridge'' by Creator/JoeHaldeman, there is a mention of the Los Alamos disaster. [[UpToEleven "Two human bodies trying to occupy the same place at the same time turned a mountain into a deep valley and spread heavy fallout from Albuquerque to Mexico City"]]
* This little ditty from ''Literature/TheRestaurantAtTheEndOfTheUniverse'':
-->''I teleported home one night, with Ron and Sid and Meg,\\
Ron stole Meggy's heart away, and I got Sidney's leg.''
* Franchise/StarTrekExpandedUniverse
** In the ''Series/StarTrekVoyager'' novel ''Pathways'', Harry Kim manages to telefrag his own foot because he stepped off the transporter pad just as it was dematerializing him. He rematerialized with his foot inside a rock wall. Justified in that the transporter they were using had been hacked together out of spare parts, with none of the normal safety features of a regulation one.
** Used intentionally by Mackenzie Calhoun in a novel using a portable transporter that can send anything a short distance away using voice commands. Mac needs to destroy a generator, but he is in the process of being pummelled by an enemy near the generator. He slips the transporter (which is the size of a coin) into the enemy's pocket and tells it to transport 5 meters to the right, which happens to be the generator. Unlike normal transporters, the portable version doesn't check first to make sure there's space available, resulting in the bad guy fusing with the generator, killing the former and destroying the latter.
* In Creator/FredricBrown's ''What Mad Universe'', it is stated that a starship's teleporting drive should only be used to travel into outer space. If you try to emerge in a place which already contains air, it's not pretty.
* This is a concern for Travelers in ''Literature/TheGrimnoirChronicles''. One of the heroes has a bug embedded in her foot when she teleports without looking.
* In the ''Literature/WorldOfTiers'' series by Creator/PhilipJoseFarmer, swap-porting and PortalCut are introduced right from the start and stay important throughout the series.
* In Russian humorous SF short story ''Monument'' by Yevgeniy and Lubov' Lukins the FirstPersonPeripheralNarrator "proves" that teleportation is impossible because of [[TeleFrag telefragging]]. Then his friend [[DieOrFly aquires]] [[StockSuperpowers the power of swap-porting]], that cuts the shape of his body and clothes out of any material. And covers the township with monuments to himself.
* The Displacers used by Literature/TheCulture manifest as a "caisson" field that appear around the target and shrink to a point to remove it, and it its destination expand from a point to the full size of the displaced object, then vanish. Careful Minds expand or contract the field carefully so as to push the air in the target area out of the way or allow it to diffuse in... rapid displacements are effectively explosions. Displacement into sealed areas is done carefully to prevent the container from bursting (or the pressure from crushing the displacee).

[[folder:Live-Action TV]]
* ''Franchise/StarTrek''
** In the ''Series/StarTrekTheNextGeneration'' episode "The Pegasus", the title ''USS Pegasus'' had a TeleFrag-like encounter with an asteroid, thanks to a cloaking device that made the ship intangible. It broke while the ship was drifting through an asteroid field, and the ship ended up embedded halfway inside solid rock.
** An early episode of ''Series/StarTrekVoyager'' had a malfunctioning food replicator (which works by a variation of the [[TeleportersAndTransporters transporter]] technology) fuse an alien halfway into the floor.
** A similar thing happens in ''[[Series/StarTrekTheNextGeneration Next Generation]]'' episode "In Theory", when a nebula has strange effects on matter: some poor crew member ends up falling partway through a floor before it becomes solid again. Not actually teleportation, but the end result is remarkably similar.
** In episodes of ''Series/StarTrekEnterprise'', a RedShirt (uh, Red Stripe?) who gets beamed up during a windstorm in a forest appears with leaves and sticks stuck in him, while another who gets beamed out in a sandstorm gets a [[BodyHorror dermis full of sand]]. They live, though. [[JustifiedTrope Justified]] because the transporter's still in beta and doesn't have filters to prevent that yet. All things considered, by far not the worst thing to happen to anybody because of the Transporters. Though it is understandable why nobody wants to actually ''use'' that thing on the show.
* ''Series/{{Battlestar Galactica|Reimagined}}''
** During a rescue mission, one of the raptors in a squad miscalculates its jump, and arrives inside a mountain.
** In "Someone to Watch Over Me", [[spoiler:when Boomer jumps while fleeing ''Galactica'', she tears out a section of the hull because she's too close.]]
** And then in the finale, "Daybreak", [[spoiler:an entire squadron of Raptors jumps out in to space from ''Galatica'''s sealed-off flightpod. It happens ridiculously quickly, but FreezeFrameBonus watching reveals the maneuver absolutely ''ruins'' the flightpod with the damage it causes.]]
* ''Series/DoctorWho''
** "Nightmare of Eden" begins with a hyperspace traffic accident that results in two spaceships interpenetrating.
** In "Remembrance of the Daleks", the Doctor sabotages a Dalek teleporter so it telefrags ''itself'', with the Dalek's insides and outsides trying to occupy the same space.
** In "The Doctor's Wife", Nephew is "[[ExpospeakGag redistributed]]" when he happens to be standing right where the Doctor's makeshift TARDIS materializes.
** Averted by the the TARDIS herself, who seems to have safeguards in place that prevent this. It's been shown that when she ''does'' decide to materialise around someone, they get deposited safely inside the main control room.
* ''Series/{{Sliders}}''
** The timer has safeguards to ensure that our heroes always slide into open air over solid ground. When malfunctioning, it's been known to send them into a broom closet or in the middle of the ocean.
** Or, in a memorable incident, half of them high in the air, landing on a window washer's rig, and the other half safely on the ground.
** Another example had the portal open halfway in a building with two of the heroes ending up inside and two outside.
* Used in ''Series/BlakesSeven'' when Creator/BrianBlessed's character, while explaining his [[EvilTastesGood thirst]] for power [[LargeHam in his usual manner]], accidentally steps onto the teleporter. The crew of the ''Liberator'' tries to send him back to his planet... but unfortunately for him, it's out of range.
* ''Series/BabylonFive''
** Jump points destroy everything around them. This is used by Minbari as weapon in the Movie "In the Beginning" and attempted by ScaryDogmaticAliens in episode "A View from the Gallery".
** Not to mention what happens when you open a jumppoint ''[[RealityBreakingParadox inside]]'' an active jumpgate. It's called the "Bonehead Maneuver". If you don't have a very very fast ship you won't get out of the blast radius, and not even warships built by the First Ones will survive it. Also worth noting that smaller, faster ships don't have the power output to generate their own jump points. The ships big enough to make their own jump points are too heavy and slow to make the getaway. It's not until they develop the [[CoolShip White Star]] in the third season of the show that they are willing to even attempt this. It's a close enough call that they don't bother to attempt it again. Plus they don't want to go around destroying jumpgates, as those are vital to any race using them. The only reason they blew up that one was because that species has recently died out from a plague (a whole earlier episode was devoted to that), so the only people using it were smugglers.
* A case of accidental telefragging in the two-part FreakyFridayFlip episode "Dreamland" of ''Series/TheXFiles''. During a test run with an experimental and top secret aircraft by the more secretive parts of the military, something went wrong that had space-time warping in the area. The results? One of the pilots is fused to a boulder and still breathing, a couple that were getting intimate is found [[BodyHorror fused together]] by their friend, and Mulder finds a pair of dimes intersecting each other at a right angle.
* In an episode of ''Series/{{Fringe}}'', a building from the other universe ends up in ours, resulting in a man being fused with parts of the building as well as his own duplicate.
* ''EarthFinalConflict''
** An episode has a man build a teleportation device, which he uses to teleport bombs directly to the target to perform assassinations. When his hideout is discovered, he promptly teleports himself to a warehouse he owns, only to be half-embedded in some shelves, which have been moved when the feds raided the place earlier. Realizing he is pretty much dead, he chooses to destroy his creation to prevent it from falling into the Taelon hands. He does this by teleporting to the same exact location. According to Augur, this will create an anti-matter explosion.
** Another example in the final season, when an [[OurVampiresAreDifferent Atavus]] female uses a modified ID portal to go back to the distant past, when the Atavus ruled the Earth, and humans were still cavemen. Renee goes after her and then jumps back. The Atavus female enters the portal, but Renee has already turned it to face a wall. The Atavus ends up embedded in it.
* The StargateVerse has the aptly-named "iris", a DilatingDoor that covers the wormhole of the eponymous Stargate. Anyone trying to enter unannounced ends up obliterated against it.

[[folder:Tabletop Games]]
* In the ''TabletopGame/{{Starfire}}'' series, ships travelling via wormhole reappear in a random position. Normally a fleet will pass through one by one to avoid accidents, but if the race involved doesn't care about losses the ships can pass through simultaneously. They risk reappearing in the same space and blowing up. The novelizations also use this one, especially ''Literature/TheShivaOption''.
* ''TabletopGame/{{Warhammer 40000}}''
** The Orks of use a heavy weapon called a Shokk Attack gun, that fires a small orkoid called a snotling through the Warp (40k's version of hyperspace and hell) to emerge inside its target. A snotling can play hell with the crew, or organs, inside an enemy unit.
** In earlier editions they also had a support gun that could teleport enemies randomly. This had predictable results if they were teleported ''down''.
** Most forms of personal teleportation in ''Warhammer 40000'' present an inverted risk: teleporting into an enemy makes YOU roll on the "Deep Strike Mishap Table" - this has a chance of making your personal teleporter ''explode'' - but does nothing to your foe (the same mechanic is used for paratroopers getting shot down and tunneling units suffering a cave-in).
** Also, daemon summmoning usually results in the major daemon appearing "in" the caster or sacrificial victim.
* ''TabletopGame/DungeonsAndDragons''
** Averted in most games: teleportation spells tend to feature a failsafe that, in the event of a spellcaster accidentally attempting to teleport himself into a wall or some other invalid location, will shunt the spellcaster to the nearest valid (read: empty) square. However, if said square is too far away from the initial target location, the spellcaster starts taking damage with every square he is shunted through. Some of the more safe variants shunts you into the Astral Plane if you can't be shunted to a nearby square. That may or may not be a bad thing, depending.
** In the 1st and 2nd editions there was no failsafe: if you teleported into a solid object, you died. That's [[ProperlyParanoid one of two]] reasons why wizards who weren't feebleminded too frequently tend to ''scry'' on poorly-known locations before jumping there, when possible. From ''AD&D 2'' on, there's also a variant of ''teleport'' that's two spell levels higher and which simply fails rather than depositing the caster off-target (even if that arrival point would also be safe).
** The Blood Magus prestige class in 3rd edition has this as an ability. You can teleport by simply entering one living being, and coming out of another one you know, wherever they are. It's normally harmless for everybody involved, but if you wish, you can make what the game charmingly calls a "catastrophic exit", literally exploding your way out of the destination point.
* ''TabletopGame/{{Paranoia}}'', on the other hand, does ''not'' have this kind of pleasant upgrade to the Teleportation power. One bad roll and you can wind up as mincemeat.
* In ''TabletopGame/{{GURPS}}'' you simply can't teleport in this way. Even a CriticalFailure lands you in an open location.
* In both ''HeroSystem 5th'' and ''6th'' editions, you can't teleport into something solid. A teleporter's "natural safety system" will automatically shift him to the nearest clear area big enough for him. However, this is a severe shock to that teleporter's system, and you don't get any defenses against that damage, so better hope the GM rolls low.
* In ''TabletopGame/{{Battletech}}'', the odds of telefragging when a Jump Ship jumps are astronomically slim due to the vastness of space. However, the annihilation of whatever interplanetary medium matter was in the destination point when a ship jumps in-system emits an electromagnetic pulse which is easily detectable.
* {{Averted}} in ''TabletopGame/{{Continuum}}'': The rules specifically state that "spanning" (instantaneous travel through space and/or time) carries no risk of materializing the spanner in a wall or solid object. Air and liquids part to make space for the spanner. When trying to span into a solid object, you will be placed near the object instead. Of course, that does not mean that spanning there is ''safe'', just that you will not occupy the same space as another object. You're still pretty much screwed if you span into the bottom of the ocean or into a furnace. The reason for this protection from materializing inside another object becomes clear when you learn about the mechanics of spanning: [[spoiler:Basically, your body is broken down at one end and rebuilt at the other by nano machines. Much of the details of this process is handled by the nano machines rather than the user, including the exact location. As such, the programming automatically avoids solid objects.]]

[[folder:Video Games]]
* Averted in ''VideoGame/{{Marathon}}'', if one stands on a teleporter exit point when another goes through the teleporter, the player on the exit point will be launched at high speeds in a random direction. If the teleporter is in a narrow hallway and it sends the launched player into the wall next to the exit point, expect LudicrousGibs, because they'll probably both have rocket launchers out.
* In the ''[[VideoGame/{{X}} X-Universe]]'' series of games, ships travel between different sectors of space through jumpgates. Jumpgates are two way, meaning that ships both enter and leave sectors from them. Meaning, you can use your jumpdrive to jump to a distant sector for a mission... right as a 5 kilometer long vessel is entering the jumpgate's event horizon (where ''you'' are). The Terran sectors in ''X3: Terran Conflict'' were notorious for this, as they have very active military patrols which fly between the smaller Terran gates very often. The issue became so annoying in ''X3TC'' that the developers changed how smaller ships enter the gate in an update -- they now fly towards it from slightly above or below, and enter the gate at its very edge, rather than the direct center, which capital ships use, in order to avoid any chance of being rammed to death by an inbound or outbound capital ship.\\\
In fairness, the devs did consider this trope. The gates and trans-orbital accelerators have a sort of traffic light system, and only the player flying on manual can run a red, so to speak. When time is not of the essence (i.e. any time you're not in danger of being shot to pieces), use the autopilot to go through the gate and you won't have any problems -- [[ArtificialStupidity most of the time]].
* Averted in ''VideoGame/{{Dishonored}}'': you can't blink anywhere outside of your visual range and even "blinking" itself is less like teleportation and more like "moving lightning-fast in a certain direction". If someone happens to step be in the way of your blink trajectory, sometimes they'll experience some very intense momentary sickness and pain.
* Telefragging [[TropeNamer got its name]] from the ''VideoGame/{{Doom}}'' series, where if someone teleported in and you were standing at that exact spot, you'd get reduced to LudicrousGibs and the teleporting player would be awarded a frag.
** The initial release of ''VideoGame/{{Doom}}'' did not have telefragging. If you tried to use a teleporter and an object or enemy was standing on the destination point, the teleporter would simply not work. This counted as a GameBreakingBug, as many levels can no longer be completed when an enemy gets "stuck" over the destination point and makes the teleporter unusable. This was fixed in a later release by making the incoming entity frag whatever is standing on the exit point, and this evolved into a gameplay mechanism.
** ''VideoGame/{{Doom}} II'''s final boss shot cubes that [[MookMaker caused monsters to teleport in when they hit the ground]]. If you were standing there, you'd die instantly, even if god mode was on (this is because god mode only protects against attacks less than 1,000 damage, and telefragging does 10,000). Interestingly, [[http://doomwiki.org/wiki/Telefrag monsters aren't allowed to telefrag]] outside of the final level. This can clearly be seen on many maps, where a huge horde of monsters teleports in -- one monster at a time, shortly after the previous one is killed.
** ''[=TNT=]/Evilution'' uses this in the final map, the player had to navigate a series of platforms and if they took the wrong path, they would be teleported into their own voodoo doll, effectively telefragging themselves.
* ''VideoGame/{{Heretic}}'' and ''VideoGame/{{Hexen}}'', being Doom-engine-based games, naturally have telefragging, though they may or may not have the restriction mentioned above of non-boss monsters not being allowed to telefrag. There are probably few Hexen players who haven't been telefragged by Korax at least once. And careful when playing co-op! If two people enter a teleporter in quick succession or even simultaneously, a double telefrag is the usual result.
* Used in ''VideoGame/TeamFortress2'' where, if an enemy is standing on top of a Teleporter and a player uses the Teleporter, they are awarded a kill (if both players are on the same team [[FriendlyFireproof nothing happens]]). A common strategy for Spies is to sap a Teleporter entrance and stand on top of it so that when the Engineer breaks the sapper, the Spy teleports through, kills the Engineer in doing so, and can sap his buildings with impunity.
** See also [[http://www.youtube.com/watch?v=2haS-3b0xZ0 this video]].
* A staple of the ''VideoGame/UnrealTournament'' series, through use of both teleporter gates or the Translocator Beacon. Also, a damaged Translocator beacon would always TeleFrag the ''user'' and credit the kill to whoever damaged the beacon, making it a good idea to leave the beacon in an out-of-the-way area when not using it as a rapid approach device. (Damaged beacons cannot be automatically recalled, either; they must be manually recovered.) If you have ImprobableAimingSkills, you could shoot the translocator beacon of anyone trying to rapidly approach with it while it's still flying through the air. Amusingly, the Translocator could be used to self-Telefrag if done properly (usually by throwing it straight up, teleporting, throwing another before falling, etc. until you reach terminal velocity). The personal teleporter refuses to activate when the beacon is under the foot of an ally, but a teleporter gate allows a player to kill allies, even when friendly fire is turned off.
* [[DiscussedTrope Discussed]] in ''VideoGame/WorldOfWarcraft'' in the "Schools of Arcane Magic" books:
-->''Make absolutely certain you know your destination before attempting to teleport... attempts to cast a teleportation "on the fly" often result in one very dead mage inside a wall, chair, or another mage. And I don't mean in a fun way.''
* ''VideoGame/{{Quake}}''
** Shub-Niggurath (named after one of HP Lovecraft's {{Eldritch Abomination}}s), the final boss, is only killable by this method. There's a weird looking pod that flies around the boss room and deposits the player wherever it happens to be when you go into the teleporter, and at one point, the pod goes into Shub's body. If you go into the teleporter at that point, the result is a VERY messy demise for the Hell-Mother.
** In Multiplayer ''Quake'', for those lucky enough to have played over LAN and not Dial-up, nested telefrags were quite common. Player A respawns and Telefrags Player B, who respawns and Telefrags Player A who Telefrags Player B who Telefrags Player A ad infitum. Naturally, this problem decreases rapidly with the size of a map and quantity of respawn points on it. This actually happened in the LetsPlay of ''VideoGame/{{Daikatana}}'' (about 10 minutes into Lair of Medusa) due to a glitch, resulting in [[HilarityEnsues much hilarity]].
** Likewise, teleporting enemies can also telefrag the player.
** In an instance of "reverse telefrag", attempting a telefrag on a player with the Pentagram of Protection causes the inbound player to explode instead. The explanation is that the inbound player "feels Satan's power".
* The teleport pads in ''VideoGame/{{Tribes}}'' (which either came with the base game or one of the most popular mods ironically played more than the real game itself) killed you if you stood on them when someone was coming through. It also would kill you if you were too heavy.
* In ''[[Videogame/{{Tribes}} Tribes 2]]'', vehicle pads will instantly kill any player standing in the way of the vehicle it's about to start building. Usually it accidentally telefrags an ally, but some players bait enemies into flying at them over the vehicle pad, then immediately build a flying vehicle as the enemy passes over, [[WeaponizedTeleportation instantly gibbing the enemy player]].
* ''VideoGame/{{Crusader}}''
** Though you can't teleport into anyone else, telepad mishaps can kill -- once, even to advance the plot!
** And then in the second game, one gets a weapon to sabotage telepads, killing anyone incoming on them.
** You can telefrag ''yourself'' that way if the pad was supposed to be your escape route later on. Time to start the level over again...
* Ill-designed maps in old FPS games (or ones subjected to abuse beyond all reason) have been known to reach a state where each character returns into play before the previous one has had time to get out of the way, causing the creation of the gib fountain.
* It's a lot worse when you don't get telefragged by bad spawns. Spending the first five minutes of a round of ''VideoGame/CounterStrike'' trying to get [[EnemyWithout separated]] from the person who spawned [[EnemyWithin into your head]] is not a good way to relax.
* ''Franchise/{{Halo}}''
** In multiplayer, if you try to go through a one-way teleporter, and somebody else is in the receiving end, you'll be blocked out for quite some time. The guy blocking will have his screen go white and his controller vibrate, and then finally he'll die and the teleporter will be sent through, receiving a telefrag for his effeorts. However, since this takes time to do, the guy trying to teleport may end up screwed if he's relying on the teleporter to escape from death, and the guy blocking will be completely unharmed.
** This can also be a tactic: sit on the exit, and wait for someone to try to use it. When your screen starts going white, step back. The traveller generally won't have time to react to that "Teleporter is blocked" message on their screen, and will appear right in front of you, facing the other way. Free kill.
** Dropped in the Mac/PC port, where corking the exit is a major part of strategy. Unfortunately, there is still one ''very embarrassing'' type of telefrag: If unattended vehicles are set to respawn and you're standing at the wrong spawn point, it will literally pounce on top of you for an instant kill.
** In Halo 4, the UNSC Infinity comes charging out of a slipspace portal and crushes a Covenant Remnant cruiser with its bow in Spartan Ops ep 1.
* ''VideoGame/TheLegendOfZeldaALinkToThePast'' as well as ''{{VideoGame/The Legend of Zelda Oracle|Games}} of Ages'', avoid this with travel between their two worlds/time periods. If you try to transport yourself into a solid object you'll flash for a bit and then be kicked back to your original position, able to adjust your position and try again.
* ''Franchise/{{Castlevania}}''
** A boss in ''VideoGame/CastlevaniaOrderOfEcclesia'' uses a glyph to pass through walls. Absorb the glyph while he's inside the wall and he dies instantly.
** In ''VideoGame/CastlevaniaI'', Dracula has a nasty habit of teleporting on top of Simon, regularly enough it may even be deliberate. It doesn't kill the player instantly, but does take a quarter of his life meter off, and is just one part of what makes the first phase of the boss fight such a challenge. Fortunately, the player gets a bit of warning as Dracula is initially intangible when he ports in, but the player has to be ''fast'' to move out of the way before the Count materializes fully.
* ''VideoGame/{{Iji}}''
** Komato Assassins carry a device that allows them to teleport around at will. They mentally map out the area prior to the fight, and are trained to stop pursuit if the prey leaves that area to avoid teleporting into a wall. As part of the backstory, Assassin Asha got too wrapped up in the pursuit of an enemy, ignored his training, and lost his arm in precisely this fashion.
** Also, Sector 8 has a Trapmine -- an item you can set on a teleport pad that goes off when anyone teleports through it, instagibbing the sucker that uses it (except in version 1.6) and rendering the teleporter unusable. [[spoiler:Do NOT use it when Dan tells you to: save it for a later teleporter in the same sector, where it is much more needed]].
* The Malor spell in ''VideoGame/{{Wizardry}}'' involves teleportation via punching in grid references for the desired area. The catch? Punch it in wrong and you could appear inside a rock or some other undesirable place, [[TotalPartyKill killing the entire party]].
* In ''[[http://www.roblox.com Roblox]]'', the [=CFrame=] system actively tries to keep players (and other objects) from sticking into each other, even if they have disabled collision. (Sidestepped by scripting and simultaniously anchoring the bricks, preventing flying stuff from going everywhere. For non-[=CanCollideable=] objects, the physics object "[=BodyPosition=]" also works.) Sometimes it also leads to players stacked up on a [=SpawnLocation=]. Telefragging must be deliberately scripted into a place (and even then it's hard.) The trope is also played straight with Regeneration Buttons: If a player stand where an object is created when the button is pushed, they are trapped inside until either they reset themselves (many in-game items have been created to do this in the most humorous way possible) or a benevolent player triggers the regen again, which normally has a delay timer. Sometimes, a place creator may actually put the regen button right below where the seat of a vehicle appears, causing the player to instantly get control of the vehicle. Kid-friendly LudicrousGibs result if a player dies in any way (being a Lego-like game, they literally fall apart, no blood involved, though a player's head may roll away to who-knows-where, taking the camera with it since the camera only watches the head, not the player as a whole), and if they were the driver of a vehicle, it also falls apart.
* ''VideoGame/{{Achron}}'' features a time specific version of this called "chronofragging". When a unit travels through time, if the location at the arrival time is occupied, the unit will chronofrag whatever unit it runs into, dealing significant damage to both units. This can most easily happen if you set a unit near a chronoporter. If the unit is standing idly for a while and gets sent back in time, it will still be standing in that spot in the past (since it hasn't moved) and will frag itself. Traditional Telefragging, however, is prevented. They just teleport slightly to the side.
* In ''VideoGame/StarControl'' and ''Star Control 2'', the special power of the [[FlyingSaucer Arilou spaceship]] is random teleport through the battlefield (a Colombus-effect bubble of space around planet). There is a small non-cumulative chance every time you teleport to end up inside the planet. This doesn't end well for you.
* In ''VideoGame/MightyFlipChamps'', teleporting into a wall would kill you.
* In its SpiritualSuccessor ''VideoGame/MightySwitchForce'', you can (and are occasionally required to) telefrag enemies by switching while an enemy is standing in front of a background block. You can quite easily do the same thing to yourself if you aren't paying attention or your timing is off, and in fact this becomes one of the biggest hazards in some later stages.
* Before Legend Entertainment got awarded with the job of making ''VideoGame/UnrealIITheAwakening'', they made a FPS based on ''Literature/TheWheelOfTime'' universe with a magic system that used Ter'Angreal as the weapons.
** One of the Ter'Angreal available in multiplayer was "Swap Places", which experienced players could use to set up a TeleFrag on their opponents. For example, sic Swap Places on your opponent, don a Fire Shield and jump into the lava. Or use it to drop the player into the ring of Explosive Wards you set up beforehand; if they're running, momentum should do the rest. Or fire it at the guy who trapped you in ice with Freeze.
** There's also Shift, which shifts you ahead about 5 feet and breaks the lock of any tracking weapons on you. It's good for escapes, but it's possible to telefrag yourself into, say, an incoming fireball.
* In ''VideoGame/StarTrekEliteForce'' multiplayer, if two or more players (or bots) try to enter a teleporter simultaneously, both will be killed in the ensuing "transporter accident."
* ''VideoGame/CommandAndConquerRedAlert''
** The original game let the Allied chronosphere perform this on when used on an APC, always disintegrating the passengers. You could only chronoshift into an empty space, though, avoiding the most common kind of telefrag.
** ''Red Alert 2'' enabled it as a viable tactic. One could even transport enemy units, meaning you could force a friendly-fire telefrag. By RA 3 you can destroy a construction vehicle using a Chronosphere and a dog.
** ''Red Alert 2'' also features accidental teleportation: if you chronoshift units onto uneven ground, units that end up on higher elevation may end up inside the ground and explode.
** For a more interesting variant, you could also chronoshift enemy land units into water and watch them die. Sadly, the expansion made this less useful, as more amphibious units got introduced in ''Red Alert 3''. Fortunately, this tactic also works with impassable pieces of terrain, so even an amphibious unit can be telefraged if you have cliff or even a building handy.
** There's also teleporting sea units onto land. Nothing quite like bombing an opponent's war factory...with ''a pair of aircraft carriers''.
* In ''VideoGame/CityOfHeroes'', you can only teleport (or teleport other people) to places you can see, but this is mainly due to game mechanics. Additionally, the game mechanics actively prevent this from happening; if someone is standing at another character's teleport destination, one of the two characters will be pushed aside.
* Mentioned in ''VideoGame/{{BioShock|1}}'' in some {{Mooks}} random dialogue when examining a corpse, "The subject... appears to have been ripped apart from the inside... probably a failed teleport.[[http://bioshock.wikia.com/wiki/Dr._Grossman]]"
* You can pull this off in ''VideoGame/{{Spelunky}}'' if you're [[YetAnotherStupidDeath incredibly careful about it.]] [[spoiler:The main use is to kill shopkeepers without it being counted against you.]]
* In ''VideoGame/TheElderScrollsIVOblivion's'' "Shivering Isles" expansion, the Daedric prince Sheogorath (the ruler of the dimension the game takes place in) executes those who break his laws by teleporting the condemned to a point well above the execution grounds, and letting them fall the rest of the way there.
* In ''VideoGame/EternalDarkness''' Trapper Dimension, the player character uses teleporters to move throughout the area. If a {{Mook}} happens to be standing where the exit is, they'll be reduced to little chunks. There's usually a [[GiantMook Horror]] standing on at least one of the exits.
* ''VideoGame/{{Gauntlet}}'' has teleport squares; beaming in from (not on) one of these could TeleFrag just about anything. Even Death.
* ''Videogame/EYEDivineCybermancy'' features "The Dragon" psychic ability. When it is used while targeting an organic enemy, it'll instantly teleport the player inside the enemy, and cause the enemy to explode in a [[LudicrousGibs shower of blood.]]
* In ''[[VideoGame/DarkForcesSaga Jedi Knight II: Jedi Outcast]]'', characters enter and respawn in a versus match through a beam of energy. Getting hit by one of these beams results in getting "crushed into another dimension by x". A more amusing example is setting the number of bots to 10 and starting up a match in the Imperial Labs: Raven map. Because of how incredibly small the map is compared to other areas, spawn points are cluttered up, if not, overlap with one another. No matter what you do, you will ALWAYS start up the game automatically telefragging an enemy or an ally, or several people at once.
* In ''PlanetSide 2'', vehicles are constructed instantly on the vehicle pads when a player requests one at a vehicle terminal. Any player or object standing on the pad when the vehicle is built will instantly die, with no exceptions. Pity the poor tank pilot who accidentally backs up onto a pad when another player on his empire builds a Flash ATV

* The ''Webcomic/AwkwardZombie'' comic in the illustration for this trope.
* ''Webcomic/{{Goblins}}''
** A variation: Big Ears has an axe which is enchanted so it will pass harmlessly through paladins rather than harming them. When the party fight [[KnightTemplar Kore]], Thaco has him throw the axe at Kore with a rope attached to it. The axe pulls the rope through Kore, but Thaco cuts the rope before it passes through completely, removing the enchantment and leaving part of the rope trapped painfully in Kore's body.
** A true Telefrag is narrowly averted when Onyx tries to [[http://www.goblinscomic.org/08052013/ teleport Minmax to the psionic engine room]]. Ruby thankfully stops her in time to explain that "position 0" is the one she's occupying right now.
* Exploited in ''Webcomic/{{Crowley}}'' by the character of the [[AntiAntiChrist same name]] to kill a demon, the spell has mass displacement so only the demon is hurt when Crowley teleports inside him and rips his way out.

* Wormholes in the ''OrionsArm'' universe would be rather dangerous to use without the safety precautions they have in place. Each wormhole's event horizon is coated by a layer of exotic matter; if anything comes in contact with this layer during transportation, everything inside is annihilated. Also, nothing larger than the wormhole itself can come within 427 AU of the wormhole (standard safety distance), or it will collapse and explode.

[[folder:Western Animation]]
* The telefragging was present in ''WesternAnimation/XMenEvolution'' -- but not for the party you'd think. Scarlet Witch messed up Nightcrawler's powers and caused him to teleport into a sign. The sign was pushed apart by Nightcrawler appearing in the middle of it. What would happen if it had been a ''person'' is left to the imagination.
* Nightcrawler pulls the "teleport your arm off" schtick with Spiral in ''WesternAnimation/{{Wolverine and the X-Men}}''. Although in this continuity, she visibly has four robotic arms, and after he yanks the fourth one off he drops them at her feet, smirks, and states she should surrender because he's "run out of fake ones" to take. (Spiral, in every continuity but this one, has six ''natural'' arms, some of which are ''part'' mechanical due to injuries received over the course of a long career as TheDragon.
* ''WesternAnimation/{{SpongeBob SquarePants}}'': [=SpongeBob=] visits Sandy and sees that she made a teleporter. Because he's getting late for work, he asks her to send him to the front of the Krusty Krab... just as Squidward was opening the door. They fuse together. Sandy tries hard to separate them but fails. Squidward has to perform, so he tries to hide the SpongeBob parts under a cape, but they are revealed. However, the audience seems to be impressed by this "freak" and they applaud. Sandy charges in with a "separator" she just invented, and not hearing Squidward's screams to leave them (he loves the applause), separates them. As most people get bored by the "normal" Squidward and SpongeBob and leave, Squidward freaks out and starts hitting random buttons on the separator to try to fuse back together. It explodes, making Squidward, SpongeBob, Sandy, Mr. Krab and Mrs. Puff all fuse together into a [[NightmareFuel disgusting blob]].

** Amazo can use powers [[PowerCopying copied from superheroes]], but only one at a time. After it used Martian Manhunter's power to [[IntangibleMan phase through]] an attack, Superboy stuck his fist inside its head as it switched to Superman's power to counterattack. [[YourHeadAsplode It didn't end well for Amazo]].
** In "Before the Dawn", M'gann (who also has phasing powers) suffers this when she attempts to phase through a door and a villain shifts the density of the door to match hers. Doesn't slice and dice, but it does knock her out until someone drags her out of the wall.
* In the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' episode "Lesson Zero", Twilight Sparkle deliberately teleports into a beach ball, causing the ball to expand and pop (with seemingly no harm to herself).
