History FusionDance / LiveActionTV

** ''Series/DenjiSentaiMegaranger'' had Giga-Guirail, the combined form of Guirail and Yugande, the Japanese counterparts of the above Darkonda and Ecliptor. In the same series, the Soldiers Kunekune can combine into the King Kunekune, which was used here for the Craterites and Craterite Conglomerate, respectively.
** In ''Series/SeijuuSentaiGingaman'', Spectral Empress Iliess can combine with the souls of her fallen Majin, becoming the monstrous Evil Empress Iliess.
** In ''Series/KyukyuSentaiGogoV'', the three Psyma Beast siblings Zoodo, Jiin, and Guuru, who were used here for Demonite, Falkar, and Thunderon, were combined into the three faced Chimera, which was used here for the monster Troika.
** TheMovie of ''Series/MiraiSentaiTimeranger'' included the return of the previous series Spell Master Pierre, who merged with unused monster Killer Boxer Boribaru, forming the gigantic Pierrebori, which was used on ''Series/PowerRangersTimeForce'' as the unrelated monster Quarganon.
** ''Series/HyakujuuSentaiGaoranger''; After being reduced to puddles of goo, the three Highness Duke Orgs are combined into the Ultimate Org Senki, who possesses elements of all their bodies.
** TheMovie of ''Series/NinpuuSentaiHurricaneger'' had the two Space Ninsaru, who could combine into the giant Ashurasaru. The series proper also had the Ninja Wolf Beasts Fangarou, who could combine to form the Giant Beast Fangerus, which was used here for the Wolfblades.

*** TheMovie of the series featured the return of every single {{Mook}} that had appeared in the series up to that point, fusing together into the Combined Combatant.

* ''Series/{{Dollhouse}}'': Echo and Alpha are both prime examples of this; to a lesser extent, other dolls are as well. Even the individual imprints are, since they are usually composites of different people made into one personality.

** ''Series/KamenRiderDenO'': Ryotaro (and to a lesser extent, Yuuto) contract with various [[NobleDemon heroic]] [[MonsterOfTheWeek Imagin]] who [[DemonicPossession possess]] their partners. This results in the possessed human's body being controlled by the Imagin and speaking with his voice while gaining some outward physical changes (like glowing eyes and a lock of hair, both in the Imagin's [[ColorCodedForYourConvenience personal color]]). This also extends to their Rider forms, where an Imagin taking control causes the Rider suit to change armor, weapons, and abilities based on the Imagin's personality. Ultimately, possession is a Power Booster for the Imagin, as having a physical body gives them advantages but their host has little to no control. Late in the series, Den-O Climax Form is a case of Five Beings, One Body; as Ryotaro is possessed by all four of his partner Imagin at once and they share control of his body. Super Climax Form from ''The Onigashima Warship'' escalates this as a case of ''Six'' Beings, One Body; as Ryotaro is not only possessed by all four of his partner Imagin, but also Sieg, at once; and all five still share control of his body.

** ''Series/KamenRiderDouble'' uses Two Beings, One Body, as when Shotaro and Phillip transform into Double, Phillip passes out and his consciousness transfers to Shotaro's body. Double himself speaks with the voices of his individual parts in unison, though both halves can also engage in conversation with each other. MidSeasonUpgrade [=FangJoker=] reverses the dynamic, using Phillip's body and Shotaro's mind, while for Double's SuperMode [=CycloneJokerXtreme=], the TransformationTrinket actually absorbs Phillip's body and merges it with Shotaro for a true Fusion Dance.

** ''Series/UltramanTaro'' can fuse with Ultraman, Zoffy, Seven, Jack, and Ace to form Super Ultraman Taro, a power booster. While his appearance doesn't change, it dramatically increases his power and allows him to fuse their powers into the Cosmo Miracle Beam.

** In the GrandFinale of ''Series/UltramanMebius'', [[spoiler:Mebius, Ultraman Hikari, and GUYS merge into Mebius Phoenix Brave mode, thanks to ThePowerOfFriendship between Mebius and his friends, and use the power of this fusion, along with Zoffy's and GUYS Light Beam Satellite to end the threat of Alien Empera once and for all.]]
** Ultraman Mebius can also fuse with the first six ultra heroes to become Infinity mode, which is used in the ''Film/UltramanMebiusAndTheUltraBrothers'' movie to battle the gargantuan U-Killersaurus. This is more of a power booster.

** Series/UltramanGinga and Ultraman Victory can become Ultraman [[BreadEggsBreadedEggs Ginga Victory]], though it required some training from Ultraman Zero to achieve it, as seen in TheMovie.

** Series/UltramanTaiga enters his Tri-Strium SuperMode by fusing with his friends, Ultramen Titas and Fuma. ''Film/UltramanTaigaTheMovieNewGenerationClimax'' takes it further by fusing all six "New Generation"-era Ultramen in their {{Super Mode}}s into Ultraman Reiga -- and three of those are ''already'' fusions (Ginga Victory, Gruebe, and Taiga Tri-Strium), which means it's actually composed of ''eleven'' Ultras.

** ''Series/UltramanTaro'' can fuse with Ultraman, Zoffy, Seven, Jack, and Ace to form Ultimate Taro, a power booster. While his appearance doesn't change, it dramatically increases his power and allows him to fuse their powers into the Cosmo Miracle Beam.

** ''Series/UltramanAce'' actually has a double example, with Ace bonding with two humans, Seiji Hokuto and Yuko Minami, who would then fuse together to give him control. [[spoiler:This is dropped after about halfway through the series when Yuko Minami [[PutOnABus leaves Earth]]] to return to her true home on the Moon.]]

* A dark example in ''Series/DoctorWho'' happens in "New Earth", since Lady Cassandra, after being reduced to a [[BrainInAJar Brain in a jar]] that controls a piece of her skin becomes interested in getting a younger body and ends up getting her hands in a body swap device called a psychograft. She uses this to possess the body of Rose Tyler at first and while her personality remains mostly the same afterwards, she does gets influenced by Rose emotionally to some extend, gaining [[VillanousCrush Rose's crush on the Doctor]] and ends up giving him a passionate kiss because of it. The fusion effects seem to be temporally as well, since It's explained that the mind and personality of the user of the psychograft [[EnemyWithin eventually replaces the original personality of the host over time.]]

** ''Series/KamenRiderDenO'': Ryotaro (and to a lesser extent, Yuuto) contract with various [[NobleDemon heroic]] [[MonsterOfTheWeek Imagin]] who [[DemonicPossession possess]] their partners. This results in the possessed human's body being controlled by the Imagin and speaking with his voice while gaining some outward physical changes (like glowing eyes and a lock of hair, both in the Imagin's [[ColorCodedForYourConvenience personal color]]). This also extends to their Rider forms, where an Imagin taking control causes the Rider suit to change armor, weapons, and abilities based on the Imagin's personality. Ultimately, possession is a Power Booster for the Imagin, as having a physical body gives them advantages but their host has little to no control. Late in the series, Den-O Climax Form is a case of Five Beings, One Body; as Ryotaro is possessed by all four of his partner Imagin at once and they share control of his body.

* ''Series/{{Dollhouse}}'': Echo and Alpha are both prime examples of this; to a lesser extent, other dolls are as well.
** Even the individual imprints are, since they are usually composites of different people made into one personality.

** In the GrandFinale of ''Series/UltramanMebius'', [[spoiler:Mebius, Ultraman Hikari, and GUYS merge into Phoenix mode, thanks to ThePowerOfFriendship, and utterly destroy the BigBad with it.]]

* ''Franchise/PowerRangers''
** ''Series/PowerRangersInSpace'': Darkonda can force Ecliptor (and possibly others, though we've never seen it) to fuse with him, becoming Darkliptor. Darkliptor has the design and weapons of both, but the voice and will of Darkonda only. (Ecliptor has been able to force a separation, but not control the combined form.) Another case of a Power Booster that looks like a Composite.
** [[Series/PowerRangersSPD Jack]], [[Series/PowerRangersMysticForce Nick]] and [[Series/PowerRangersOperationOverdrive Mack]] ALL gained their "battlized" forms by fusing with allies: the RobotBuddy R.I.C, the dragon Fireheart and the Sentinel Knight. Sentinel could talk (through a giant face on the armor; it's as unnerving as it sounds) but it's not clear if he could take the driver's seat. Again, Power Booster disguised as Composite.
* In one episode of ''Series/StarTrekVoyager'', Neelix and Tuvok are accidentally merged together. The new hybrid character "Tuvix" (played by a new actor) didn't want to be separated, and Captain Janeway did it by force. Tuvix had several of the positive traits of both component beings, including a sense of humor (which Tuvok didn't have) and edible cooking (Neelix was a decent cook, but all the dishes he knew how to prepare were radically different from Alpha Quadrant tastes).
** The [[Series/StarTrekTheOriginalSeries Original Series]] episode "Metamorphosis" resolves with [[spoiler: the EnergyBeing called the Companion merging with a lonely dying woman named Nancy Hedford, thus saving her life and giving the Companion the physical body she needs to properly court Zeffram Cochrane, whom she loves (and giving Nancy Hedford a chance to finally experience love). The resulting personality is a Composite of the Companion and Nancy.]]

** In the climax of season 4, the Slayer temporarily merges (mentally) with her three sidekicks to acquire Willow's magical talent, Giles's obscure knowledge, and Xander's heart. (If you're thinking [[WhatKindOfLamePowerIsHeartAnyway so what]], go watch any number of episodes where he demonstrates non-powered bravery.)

* The ''Franchise/UltraSeries'' often uses a Switcher-type for its heroes, having an alien Ultra-being bond with a (typically recently dead) human. There have also been composite types.
** ''Series/UltramanAce'' actually has a double example, with Ace bonding with two humans, Seiji Hokuto and Yuko Minami, who would then fuse together to give him control. [[spoiler:This is dropped after about halfway through the series when Yuko Minami [[PutOnABus leaves Earth]]] to return to her true home on the Moon.]]
** Series/UltramanCosmos and Ultraman Justice fuse into Ultraman Legend in TheMovie ''Film/UltramanCosmosVsUltramanJusticeTheFinalBattle''. It's hinted that Legend is their original identity and that Cosmos and Justice are a LiteralSplitPersonality.
** In the GrandFinale of ''Series/UltramanMebius'', [[spoiler:Mebius, Ultraman Hikari, and GUYS merge into Phoenix mode, thanks to ThePowerOfFriendship, and utterly destroy the BigBad with it.]]
** Ultraman Mebius can also fuse with the first six ultra heroes to become Infinity mode, which is used in the ''Film/UltramanMebiusAndTheUltraBrothers'' movie to battle the gargantuan U-Killersaurus. This is more of a power booster.
** Franchise/UltramanZero, Series/UltramanDyna, and the before-mentioned Cosmos fuse into ''Film/UltramanSaga'' in the movie of the same name in order to battle the {{kaiju}} Hyper Zetton.
** Series/UltramanGinga and Ultraman Victory can become Ultraman [[BreadEggsBreadedEggs Ginga Victory]], though it required some training from Ultraman Zero to achieve it, as seen in TheMovie.
** Series/UltramanOrb, Series/UltramanGeed, and Series/UltramanZ ''look'' like they're composites of themselves and two to three other Ultramen, but the trope is averted since they're really just PowerCopying. Though forms based on the evil [[Franchise/UltramanZero Ultraman Belial]] do tend to have a bit of his personality seep through.
** In ''Series/UltramanRB'', Ultramen Rosso and Blu can merge into Ultraman Ruebe. In TheMovie, they take it a step further by also merging with their little sister Ultrawoman Grigio, becoming Ultraman Gruebe.
** Series/UltramanTaiga enters his Tri-Strium SuperMode by fusing with his friends, Ultramen Titas and Fuma. ''Film/UltramanTaigaTheMovieNewGenerationClimax'' takes it further by fusing all six "New Generation"-era Ultramen in their {{Super Mode}}s into Ultraman Reiga -- and three of those are ''already'' fusions (Ginga Victory, Gruebe, and Taiga Tri-Strium), which means it's actually composed of ''eleven'' Ultras.
** There are a number of kaiju fusions as well:
*** ''Orb'', ''Geed'', and ''Z'' all had villains who had dark counterparts of the heroes' TransformationTrinket, and used its multi-part PowerCopying to create fused kaiju like Zeppandon (Zetton and Pandon), Skull Gomora (Gomora and Red King), Thunder Killer (Eleking and Ace Killer), and Pedanium Zetton (Zetton and King Joe).
*** Five King appeared in ''Series/UltramanGinga S'' as a fusion of Golza, Melba, Reicubas, Gan-Q, and Super C.O.V. Other fusions in this "line" appeared later, as ''Series/UltramanZ'' saw it appear first as Tri-King (with just Golza, Melba, and Super C.O.V.) before being upgraded to Five; and then ''Series/UltramanTriggerNewGenerationTiga'' had just Golza and Melba fused into Golba.
* ''Series/{{Dollhouse}}'': Echo and Alpha are both prime examples of this; to a lesser extent, other dolls are as well.
** Even the individual imprints are, since they are usually composites of different people made into one personality.

* The live-action series ''Shazam!'' features the Billy Batson/Captain Marvel Switcher.
* In ''Series/EarthFinalConflict'', the Taelons and Jardians used to be one species, the Atavus, but millions of years ago they split into two. At one point Da'an tries to merge his energy with a Jardian. [[spoiler:It works for about a minute, before the fusion splits apart. Da'an survives but the Jardian is killed.]] Later, [[spoiler:six Taleons and six Jaridians attempt the same thing, this time with the aid of special chambers. [[WhatHappenedToTheMouse We do not learn what became of them after this.]]]]
* Its companion series ''Isis'' (AKA ''The Secrets of Isis'') features Andrea Thomas transforming into the Egyptian goddess Isis.

* ''Series/MysteryScienceTheater3000'' "Mitchell":
--> '''Dr. Forrester:''' "Oh, Frank, look! Remember? The double butt graft! My science project from Evil-O's. I grafted the butt of a dog onto the butt of a cat. Sure, they all laughed...."
* Firestorm appears in the ''Series/{{Arrowverse}}'' first as the fusion of Martin Stein and Ronnie Raymond on ''Series/TheFlash2014'' then as Stein and Jefferson Jackson on ''Series/LegendsOfTomorrow''. An evil Earth-2 version, Deathstorm, also appears in one ''Flash'' episode.

** Five King appeared in ''Series/UltramanGinga S'' as a fusion of Golza, Melba, Reicubas, Gan-Q, and Super C.O.V. Other fusions in this "line" appeared later, as ''Series/UltramanZ'' saw it appear first as Tri-King (with just Golza, Melba, and Super C.O.V.) before being upgraded to Five; and then ''Series/UltramanTriggerNewGenerationTiga'' had just Golza and Melba fused into Golba.

** Series/UltramanCosmos and Ultraman Justice fuse into Ultraman Legend in TheMovie ''Film/UltramanCosmosVsUltramanJusticeTheFinalBattle''.

** There are a number of kaiju fusions as well; for instance Jugglus Juggler fuses Zetton, Pandon, and Maga-Orochi into "Zeppandon" in ''Series/UltramanOrb'' [[spoiler:and when he reappears in ''Series/UltramanZ'']].
** In ''Series/UltramanTriggerNewGenerationTiga'' the Dark Giant Carmeara uses her dark powers to fuse [[Series/UltramanTiga Golza and Melba]] into a singular entity, Golba in order to access Ultraman Trigger's tomb and destroy it.

** ''Series/UltramanAce'' actually has a double example, with Ace bonding with two humans, a man and a woman, who would then fuse together to give him control. [[spoiler:This is dropped after about halfway through the series when Yuko Minami (the woman) is PutOnTheBus.]]

* In ''Series/EarthFinalConflict'', the Taelons and Jardians used to be one species, the Atavus, but millions of years ago they split into two. At one point Da'an tries to merge his energy with a Jardian. [[spoiler:It works for about a minute, before the fusion splits apart. Da'an survives but the Jardian is killed.]] Later, [[spoiler:six Taleons and six Jaridians attempt the same thing, this time with the aid of special chambers.

** Series/UltramanCosmos and Ultraman Justice fuse into Ultraman Legend in TheMovie ''Ultraman Cosmos vs. Ultraman Justice: The Final Battle''.

** Ultraman Mebius can also fuse with the first six ultra heroes to become Infinity mode, which is used in the ''Mebius and the Ultra Brothers'' movie to battle the gargantuan U-Killersaurus. This is more of a power booster.
** Franchise/UltramanZero, Series/UltramanDyna, and the before-mentioned Cosmos fuse into Film/UltramanSaga in the movie of the same name in order to battle the {{kaiju}} Hyper Zetton.

** Series/UltramanTaiga enters his Tri-Strium SuperMode by fusing with his friends, Ultramen Titas and Fuma.

Though forms based on the evil [[Franchise/UltramanZero Ultraman Belial]] do have a bit of his personality seep through.

** Series/UltramanGinga and Victory can become Ginga Victory, though it required some training from Ultraman Zero to achieve it, as seen in TheMovie.
** Averted by Series/UltramanOrb and Series/UltramanGeed. Their various forms ''look'' like they're composites of themselves and two other Ultramen (or three in the case of Orb Trinity), but they're really just PowerCopying. Though forms based on the evil [[Franchise/UltramanZero Ultraman Belial]] do have a bit of his personality seep through.

** In S''eries/SeijuuSentaiGingaman'', Spectral Empress Iliess can combine with the souls of her fallen Majin, becoming the monstrous Evil Empress Iliess.

* ''Series/HyakujuuSentaiGaoranger''; After being reduced to puddles of goo, the three Highness Duke Orgs are combined into the Ultimate Org Senki, who possesses elements of all their bodies.
* In ''Series/KaizokuSentaiGokaiger'', when Gai can't decide which of ''[[Series/EngineSentaiGoOnger Go-onger]]'''s {{Sixth Ranger}}s he wants to [[PowerCopying transform into]], the keys combine into one that has the power of both Go-on Wings. A Composite type, since the suit is half-and-half ala Double (he even riffs on their catchphrase), and Gai has two Rocket Daggers available.

** And then there's his SuperMode, gained by merging all the SixthRanger keys into the Golden Anchor Key.
** An {{Omake}} has Gai and Marvelous fuse together into a hilarious mishmash of each other, which passes down to their initial transformation, which utterly confuses the announcer upon seeing the silver jacket of [=GokaiSilver=] with the red helmet and boots of [=GokaiRed=]
** TheMovie of the series featured the return of every single {{Mook}} that had appeared in the series up to that point, fusing together into the Combined Combatant.
* This actually happens a lot in many seasons of Franchise/SuperSentai, usually with villains and monsters.
** In TheMovie of Series/JAKQDengekitai, the Crime Big Four merge to form the Big Four Robo, though it bears little resemblance to any of the four.
** Series/GoseiSentaiDairanger features the Gorma Four Deva Kings, whose combined form was used on Series/MightyMorphinPowerRangers as the generic monster Four Head. Later, in TheMovie of the Series, which went unadapted, The Duke Of Cards used his magic playing cards to merge himself and four other revived monsters into Great King Ojaru.
** Series/ChourikiSentaiOhranger had Yokai Onbu Obake, and Machine Beast Bara Gear, who merged together to form “Onbu-Gear”. Used for Impursonator and Cog Changer on Series/PowerRangersZeo, who formed “Cog-Impursonator”.

** Towards the finale of Series/BakuryuuSentaiAbaranger, two of the main villains, Visionary Messenger Voffa and Creative Messenger Mikela are merged into the monster Dezumovoorla, the temporary host of their master Wicked Life God Dezumozorlya. Used on Series/PowerRangersDinoThunder as an unnamed monster of the week.
** Series/KaitouSentaiLupinrangerVsKeisatsuSentaiPatranger had this as a regular for the Patrangers. To be specific, all three members fused into one body when using Good Striker as the key for the fusion. Due to not being assign individual SuperForm like their counterparts, Lupinranger, this becomes their regular form when doing finisher. The Lupinrangers also had one but as a summer movie exclusive, which is Lupin Tri-Colour.

* Firestorm appears in the ''Franchise/{{Arrowverse}}'' first as the fusion of Martin Stein and Ronnie Raymond on ''Series/TheFlash2014'' then as Stein and Jefferson Jackson on ''Series/LegendsOfTomorrow''. An evil Earth-2 version, Deathstorm, also appears in one ''Flash'' episode.
