* ''Series/DoctorWho'':
** Variation: thanks to TheNthDoctor, there's currently thirteen[[note]]counting the War Doctor[[/note]] different incarnations of the Doctor running around the space/time... it's extremely rare for them to meet (TimeyWimeyBall, actors dying and all that), but when they do the result tends to be similar to this trope. ''Webcomic/The10Doctors'' is an artist's rendition, shall we say, of how the first ten Doctors would act if forced to cooperate.
** A straight example in [[Recap/DoctorWhoS30E17E18TheEndOfTime "The End of Time"]]: The Master hijacks the Immortality Gate to transform the entire human race except for Wilf [[note]](locked in a radiation-shielded room)[[/note]] and Donna [[note]](thanks to the events of [[Recap/DoctorWhoS30E13JourneysEnd "Journey's End"]] making her half-Time Lord)[[/note]] into "The Master Race", a planet-wide population of (insane, madly laughing) Master copies.[[note]] ([[FridgeLogic Wasn't River Song on Earth during this time too?]] And [[Recap/TheSarahJaneAdventuresNYSInvasionOfTheBane Luke is an artificial human]] [[FridgeHorror so he likely saw Sarah Jane become the Master]])[[/note]]
** Also in [[Recap/DoctorWhoS14E3TheDeadlyAssassin "The Deadly Assassin"]], while in the Matrix, the assassin takes on various generic historical personas (a samurai, a clown, a UsefulNotes/WW1 biplane pilot, etc.) to attack/frighten the Doctor (and the audience). At one point several of him seem to man several positions on a train (or trains) simultaneously to run over the Doctor's leg.
** In another Fourth Doctor story, [[Recap/DoctorWhoS18E1TheLeisureHive "The Leisure Hive"]], the villain Pangol used a form of AppliedPhlebotinum to recreate himself thousands of times over as a conquering army. Thanks to the Doctor's interference he ended up with an army of Doctors, which disintegrated within minutes of their generation.
* An arc in the later seasons of ''Series/StargateSG1'' had Baal make dozens of clones of himself, and in a few episodes set on Earth at least five of them hung out together. One episode even has a GottaCatchThemAll where the heroes travel the galaxy, trying to scoop up all the Baal clones. A freeze frame near the end of the episode shows fifteen clones in one room. It turns out [[spoiler:it was a BatmanGambit. Baal knew the heroes would give him the info he wanted to buy time when he had hostages, as long as they knew he couldn't escape with that info. And the clones? Each one has a transponder, too weak to be detected, but if they all stand in one place...]]
* ''Series/{{Battlestar Galactica|2003}}'': it's a natural state for them (or as natural as {{Artificial Human}}s ever get), but each of the Significant Seven models has an army's worth of clones.
* ''Franchise/PowerRangers''
** Used in a ''Series/MightyMorphinPowerRangers'' PSA to show that differences between people is a good thing.
** ''Series/PowerRangersSPD'': Yellow Ranger Elizabeth "Z" Delgado has this ability.
** The MonsterOfTheWeek of an episode of ''Series/PowerRangersDinoThunder'' had the power to create copies of anything in front of him. At one point, he made three copies of Cassidy on the spot, and the four of them proceeded to drive Devin crazy by stacking him with chores.
* An episode of ''Series/{{Eureka}}'' features Dr. Stark accidentally cloning himself. The clones try to take over the world. Long story.
* In the ''Series/MysteryScienceTheater3000'' episode covering ''Film/TheHumanDuplicators'', Tom Servo ends up cloning himself dozens and dozens of times during a host segment, creating a small herd of Servos to menace Crow with. Strangely enough, this is one gag that doesn't SnapBack, and the surplus Servos end up as recurring supporting characters, usually whenever Servo wants to perform with the [[Film/TheStarfighters United Servo Academy Mens' Chorus]] or the [[Film/QuestOfTheDeltaKnights Sir Thomas Neville Servo Consort of the Middle Ages Just-After-the-Plague Singers]]. In the [[Film/DangerDiabolik final episode]], Servo cleans up this dangling plot thread by [[StuffBlowingUp blowing up]] all the doppelgangers.
* ''Series/RoundTheTwist'' has a character make only one clone to win a running competition. However, a rabbit starts cloning an army of itself with the machine. All the objects used in the machine, cloned or original, begin to dissolve eventually, due to a fault in the machine. At least one rabbit survives, though, because in the final scene we learn what happened when Bronson put her with a male rabbit.
* [[DeadpanSnarker Jed Garrity]] gains this power at the end of ''Series/TheFortyFourHundred''.
* Eli, Samuel Sullivan's right-hand man (men?) in ''Series/{{Heroes}}''.
* ''Series/KamenRiderOOO'' has this power as the SetBonus for his [[JackOfAllStats Gatakiriba]] [[MultiformBalance Combo]]. It doesn't get used very often because (InUniverse) it's physically taxing and because (in RealLife) it's reportedly a very expensive effect. TheMovie contains a [[CrowningMomentOfAwesome special usage]], where OOO splits into eight copies and then each one transforms into one of his primary Combos to fight the BigBad.
* In ''Series/GameOfThrones'' the warlock Pyatt Pree appears to create a double of himself, although many of those watching think the warlocks are charlatans and this is just a trick. [[spoiler:It's revealed in the next episode that he really can do this, and create more than a single copy too.]]
* This happens a couple of times on ''Series/{{Charmed}}'':
** In the episode "Which Prue is it Anyway?", Prue decides she needs a power boost, and casts a spell to triple her power. Unfortunately, she doesn't realize that what it actually does is create three of her. It turns out to be useful, after all, because the two clones end up dying instead of the original Prue.
** When Piper finds out that [[TheGrimReaper the Angel of Death]] is after her husband Leo in the episode "Vaya con Leos", she decides to cast a spell to hide him. While the spell does confuse the Angel of Death, it had an unintended effect: ''every man in San Francisco'' got turned into a clone of Leo.
* In the "[[Recap/TheFlash2014S1E2FastestManAlive Fastest Man Alive]]" episode of the 2014 ''[[Series/TheFlash2014 The Flash]]'' series, Barry has to fight another [[DifferentlyPoweredIndividual meta-human]] who eventually gets named Multiplex. Multiplex's body, after the S.T.A.R. Labs particle accelerator explosion, appears to be made out of stem cells, which he can split off into copies of himself as he chooses (even clothes, apparently). All the copies are under his direct mental control. His main goal is to [[spoiler:get revenge on [[CorruptCorporateExecutive Simon Stagg]], who stole his organ cloning research and fired him before Multiplex could use it to save his dying wife]]. As the good guys figure out, Multiplex can be spotted among his doubles by the amount of stress he experiences from controlling the HiveMind. [[spoiler:Thanks to his hyper-accelerated perception, Barry is able to spot beads of sweat on one of the figures among the hundred or so copies]].
* In one episode of ''Series/TheMuppetShow'', Beaker accidentally ends up in a copying machine. The result is a multitude of Beakers, [[TheDogBitesBack who all gang up on Dr. Honeydew]]. Eventually they take over the whole show, replacing the Electric Mayhem and even JustForFun/StatlerAndWaldorf.
** In the later series ''Series/MuppetsTonight'', Gonzo somehow creates multiple copies of himself to perform a musical number. Fittingly, that number is [[Music/BillyIdol Dancing With Myself]].
** Kermit also appeared with two duplicates of himself on ''Muppets Tonight'', performing [[Music/TalkingHeads "Once In a Lifetime"]] in a parody of ''Film/StopMakingSense''.
* In ''Series/{{Powers}}'' this is Simons' power.
