Twins are natural TagTeam partners. Besides having all that [[CreepyTwins creepy twin stuff]] going for them, they also have one trick few others can match -- they can easily [[TwinSwitch swap places]], allowing the fresh sibling to take an injured one's place.

[[FreudWasRight Nothing to do]] with the TwinThreesomeFantasy. Compare and contrast TwinSwitch, where twins trade places or lives.

* In ''Film/ThePrestige'', the main character goes to great lengths, so far as violating the laws of physics, [[spoiler: replicating and one-upping a magic trick performed by a man who was secretly twins]].
* In ''Film/JaneDoeTheTiesThatBind'' the main suspect appears to have a solid alibi, being on camera somewhere, [[spoiler: but later on we find out there is a twin brother, and even a third identical brother involved.]]

[[folder:Literature]]
* In the ''Literature/HarryPotter'' novels, Fred and George Weasley act as tag-team twins on the Quidditch field as beaters, redirecting heavy, self-propelled balls towards the opposing team.

[[folder:Live Action TV]]
* In an episode of ''Series/{{NCIS}}'', the team figures out how a serial murderer committed their crime with an alibi to back them up.
* On ''Series/XenaWarriorPrincess'' a wrestling show solves the problem of the twin switch by making twin teams compete in tornado matches instead of tag matches.

[[folder:Professional Wrestling]]
* The Harris Brothers, in their various guises (The Blu Brothers, Disciples of Apocalypse, et. al.), loved to do this.
* As did the Shane Twins (a.k.a. The Gymini, or infamously in {{TNA}}, The Johnsons [don't ask]).
* The Basham Brothers are a famed practitioner of the Tag Team Twin trick as well, despite the fact that they're [[UnrelatedBrothers not even related]] (just have similar builds and bald heads).
* Mercilessly parodied by The Dudley Boyz when they were on ''Wrestling/{{WWE}} [=SmackDown=]!'', as CorruptCorporateExecutive Paul Heyman claimed, at length, that he couldn't tell them apart at all, and thus they got away with switching at will. For the record, one of them is ''white'' and the other is ''black''.
** They once managed to do it in TNA. The switch istelf was done while the referee was temporary blinded, but you'd think that if he could see well enough to count the pin, he'd also be able to see that it was the wrong wrestler doing the pinning.
* The masked tag team The Killer Bees made this such an integral part of their act that, when they had a HeelFaceTurn and took off their masks, they ''still'' kept doing this trick, as the Bee on the outside would quickly put his mask on and take his partner's place. This is kind of ridiculous if you think about it; we all know [[EasilyDistractedReferee pro wrestling referees aren't the sharpest knives in the drawer]], but you'd think a ref would notice that the guy suddenly has a mask on when "he" didn't before...
** It made perfect sense - inasmuch as anything does in wrestling - because BOTH guys would put on their masks, so the ref had no idea who the one being beaten on seconds earlier was.
*** However, for whatever reason, when Wrestling/KokoBWare tried the trick while teaming with the Bees, the ref caught on. Don't know how that could have happened....
* Billy and Benny [=McCrary=] were Tag Team Twins, as well as the world's heaviest twins.
* The Haas Brothers Charlie and Russ could pull this off. Unfortunately Russ died before making it to the WWE.
* Subverted: The Briscoe Brothers are neither Briscoes (the legal name is Pugh) nor twins (Jay was born a year and a week before Mark), but they are real brothers. They pulled the twin-switch a few times earlier in their careers, though - however, since then, they have gotten extensive tattoos that make it easier to tell one from the other (with Mark Briscoe's missing front teeth giving away the difference pretty handily). After all, it's hard to mistake Jay for Mark when he has "Jay" tattooed on his arm...
* ''Wrestling/{{WWE}} Smackdown!'''s Brie and Nikki Bella often employed this trope early in their tenure, when Brie was a singles wrestler and Nikki was yet to be revealed. They eventually got exposed by Victoria and Natalya, and then began wrestling as a tag team, still doing the switch on occasion.
** They kept doing it a couple of times after returning in 2013, even though Nikki had gotten breast implants which Brie was missing, making them more easy to tell apart. Jerry Lawler kept pointing this out on commentary.
* Subverted by Wrestling/TheUsos. Despite being twins, pointing out the fact most people couldn't even tell them apart and being {{Heel}}s, they refused to fall back on this trick. [[{{Reconstruction}} Then they tried playing it straight after a losing streak on WWE Superstars.]]
** An inadvertent version of this ended up biting them in the ass; during a match with Wrestling/TheWyattFamily, during a chaotic melee one of the Usos ended up taking a hard shot and getting pinned. The problem is that it was ''the wrong Uso''; the ref couldn't tell that the one who got pinned wasn't the legal man because they looked so much alike.
* The Body Donnas (who, like the Bashams, weren't really related but used similar hair styles, builds and identical costumes to play twins) did this on a regular basis during their WWE (then WWF) run, but had it backfire when one of the brothers was booked in a singles match against Ahmed Johnson. Despite the twins switching behind the ref's back, Johnson simply picked up where he left off and continued to beat down whichever twin was in the ring. Then the ref caught them trying to swap again and chased the ''legal'' twin out; he turned back just in time for Johnson to hit his finisher and get a three-count on the "wrong" man.
* Inverted when face team The Headbangers, while not identical, looked similar enough to use this trick to steal a win from heels Marc Mero and Golddust.
* The Quebecers tried this once. The obviously fatter Pierre was quickly called out on it by the referee, despite scrunching himself down as small as possible to look more like Jacques.
* OVW has the Blossom Twins, who used this trick to defeat the Glamazon's SuspiciouslySimilarSubstitute Epiphany, [[MakeWayForTheNewVillains in their debut match]].
* The Brahman Brothers (a.k.a The Sato Twins) are the kings of this trope in Japan. Back in Toryumon X, they were considered ''one wrestler'' and were allowed to compete in matches as the same person, as the referee couldn't tell them apart and was forced to permit it.
* Brad and Bart Batten were a popular tag team in the Central States promotion in TheEighties. Being faces for most of their career, their TwinSwitch tactics were usually PlayedForLaughs.

[[folder:Real Life]]
* Twins have played collegiate and professional sports as teammates. While sometimes they differ in abilities, many times their skill sets are sufficiently similar that they can and are used interchangeably. Examples include Markieff and Marcus Morris of the Phoenix Suns, and David and Travis Wear of the UCLA Bruins basketball team.
[[/folder]]

[[folder:Video Games]]
* Ingo and Emmet the Subway Bosses from ''VideoGame/PokemonBlackAndWhite''
* [[spoiler:Aegina and Luciana]] from ''YggdraUnion'' use similar tactics on a larger scale, retreating when one is about to be beaten and letting the other attack shortly afterwards - and until they're both on the same battlefield, the game displays both of their names as [[spoiler:Aegina]]. However, there's enough differentiation between them that a sharp-eyed player can tell them apart.
* Kirara and Sarara fights as a team in the Story mode of ''MagicalBattleArena'', and even their opponents will comment that their being twins made them formidable opponents after the battle.
* In ''VideoGame/MagicalGirlLyricalNanohaAsPortable: The Gears of Destiny'', the [[CatGirl Liese Twins]] play like this. They are selected as one character in the game, and they fight by switching in and out to execute their various moves.
* [[spoiler:Eliza and Isabella]] in ''VideoGame/CustomRobo'' on the Gamecube. First hinted at when [[spoiler:Eliza seems to have somehow got amnesia and forgotten all about the promise she made to Evil]], actually revealed near the very end of the game. However, this can be spotted in paying attention to the parts they use.
* ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' has ''two'' battles like this in Dodongo's Cavern. Both times, Link is pitted against two Lizalfos, who attack him one at a time and switch places after the current fighter takes a certain amount of damage.

[[folder:Visual Novels]]
* Mion and Shion in ''VisualNovel/HigurashiNoNakuKoroNi'' during the game segments.
* Hisui and Kohaku from ''VisualNovel/{{Tsukihime}}'' can fight as a tag-team in the fighting game spinoff ''VideoGame/MeltyBlood''.
[[/folder]]

[[folder:Webcomics]]
* Used ''against'' the York Sisters in ''Webcomic/RivalAngels''. Damage Inc. beat up one of the twins outside the ring, and then roll her in while the referee's distracted for an easy pin.
