History FusionDance / WesternAnimation

* In the penultimate episode of the second season of ''[[WesternAnimation/JusticeLeague Justice League Unlimited]]'', "[[Recap/JusticeLeagueUnlimitedS2E11PanicInTheSky Panic in the Sky]]", [[spoiler:Lex Luthor convinces Brainiac to merge with him. The resulting godlike being possesses all of Brainiac's power and knowledge combined with Luthor's ego and ambition]].

* In the penultimate episode of the second season of ''[[WesternAnimation/JusticeLeague Justice League Unlimited]]'', "Panic in the Sky", [[spoiler:ComicBook/LexLuthor convinces ComicBook/{{Brainiac}} to merge with him. The resulting godlike being possesses all of Brainiac's power and knowledge combined with Luthor's ego and ambition.]]

* The second SeasonFinale/last episode ever of ''WesternAnimation/LegionOfSuperheroes'' featured a Composite of Franchise/{{Superman}} and his clone-from-the-future (er, ''further'' into the future), Superman X. It was accomplished with Saturn Girl's PsychicPowers, as it was technically a BattleInTheCenterOfTheMind.

* An episode of ''[[WesternAnimation/{{Superfriends}} The Superfriends]]'' has Green Lantern using his ring to fuse himself and Superman to deal with the day's NegativeSpaceWedgie.
* The 2000s ''WesternAnimation/{{Teenage Mutant Ninja Turtles|2003}}'' animated series features an involuntary fusion of two villains, Drako and The Ultimate Ninja, into a powerful but terror-inducing form.

* WesternAnimation/YoungJustice2010: The Forever People, a group of five New Gods from New Genesis, have the ability to fuse into the 10-foot tall being Infinity-Man.

* The Trix in the Season 2 finale of ''WesternAnimation/WinxClub'' merge together into an even more powerful being.

* In the short-lived ''WesternAnimation/MortalKombatDefendersOfTheRealm,'' Nightwolf was the team SmartGuy and seldom joined the others in battle, preferring to stay back with his pet wolf and man the computer systems. When important missions did require him to accompany the team, he would merge with the wolf as a Power Boost when kombat got thick and open a can of whoop-ass on the {{Mooks}}. It was quite awesome to see and helped to break the monotony of the show, though he only did it like three times over the course of the series.

* ''Franchise/{{Transformers}}'' ''loves'' this.
** You've got the gestalts like Devastator, Optimus Maximus, and, well, ''lots'' of things. Given that they're MechanicalLifeforms, they kinda toe the line between this and CombiningMecha.
** Groups like the Constructicons or Aerialbots are CombiningMecha. The 'Spark of Combination' from Anime/TransformersEnergon would count as this trope, as would Optimus Prime's combined super modes from Cybertron as Composite/Powered Up combinations.
** This can vary by continuity. Combiners like Devastator and Superion are usually a Composite. The component 'bots go through a mental fusion to create the gestalts mind and personality. The more in sync a team is, the more mentally stable the resulting gestalt is.
*** Though Generation 1 had various combiners, the episode "Masquerade" featured a pseudo-Combiner when Optimus Prime, Jazz, Sideswipe, Windcharger, and Mirage disguised themselves -- with paint -- as the Stunticons to learn Megatron's newest scheme. All hell broke loose when Menasor (the real Stunticons in their combined form) showed up. In order to fool the Decepticons into thinking the real thing was a fake, the Autobots formed a second Menasor using Windcharger's magnetic powers and Mirage's illusion-projecting ability. (The fake Menasor was effective until it had to fight.)
** There are also groups like the Headmasters and the Powermasters where a humanoid in a mech suit can transform into the head or power source of the Cybertronian. There were also Targetmasters, but the humanoid or Cybertronian only transformed into the weapon of the Transformer and didn't physically merge, so they would not be an example. (The exceptions being the Targetmasters in the Japanese ''Headmasters'' series, as the smaller partner's interface replaced the larger robot's right hand with a gun, rather than the larger robot simply holding their gun/partner.)
** The ''Anime/UnicronTrilogy'' had Optimus Prime being able to combine with at least two separate Autobots in each series.
* An episode of ''[[WesternAnimation/{{Superfriends}} The Superfriends]]'' has Green Lantern using his ring to fuse himself and Superman to deal with the day's NegativeSpaceWedgie.
* The second SeasonFinale/last episode ever of ''WesternAnimation/LegionOfSuperheroes'' featured a Composite of Franchise/{{Superman}} and his clone-from-the-future (er, ''further'' into the future), Superman X. It was accomplished with Saturn Girl's PsychicPowers, as it was technically a BattleInTheCenterOfTheMind.

When important missions did require him to accompany the team, he would merge with the wolf as a Power Boost when kombat got thick and open a can of whoop-ass on the {{Mooks}}. It was quite awesome to see and helped to break the monotony of the show, though he only did it like three times over the course of the series.
* ''WesternAnimation/ReBoot'':
** An episode has main villain viruses Megabyte and Hexadecimal merge (via a third component, a Web Virus) to make an even more powerful hybrid called Gigabyte, who is specifically said to have both Megabyte's strength and Hexadecimal's special powers. Season 4 reveals that this fusion is more of a recombination; Megabyte and Hexadecimal used to be a single virus, [[PunnyName Killabyte]], who upgraded into Gigabyte and then split into Megabyte and Hexadecimal shortly after being portaled into Mainframe.
** In Season 3, Bob performs a Power Booster. He [[spoiler:merges with his (damaged) keytool Glitch upon being reunited with it toward the end of the third season. This actually ends up causing problems for him in the fourth season, as the merge didn't quite work right due to Glitch's damaged state. It's mentioned that if he continues to use his Glitch powers he'll eventually die because of it. He manages to split from Glitch (though he decides to separate from Glitch because he believes he can win Dot's love that way, not because he's going to die!) a few episodes later, returning him to his original look. Glitch also returns, repaired and upgraded]].

* In the ''WesternAnimation/{{Gargoyles}}'' episode "Grief", a magic scroll fuses an avatar with Anubis, god of death. Pack member Jackal interrupts the ritual for it and combines with him, causing some prime terror in the process.

* The Trix in the season 2 finale of ''WesternAnimation/WinxClub'' merge together into an even more powerful being.
* In the penultimate episode of the second season of ''[[WesternAnimation/JusticeLeague Justice League Unlimited]]'', "Panic in the Sky", [[spoiler:ComicBook/LexLuthor convinces ComicBook/{{Brainiac}} to merge with him. The resulting godlike being possesses all of Brainiac's power and knowledge combined with Luthor's ego and ambition.]]
* The animated movie ''WesternAnimation/TheGuardiansOfTheLostCode'', uses a combination the composite and power booster, with the "Warrior Form" between a human and a [[{{Mon}} brije]]: The fusion increases the human's physical strength and multiplies the brije's magical powers.

* In the ''WesternAnimation/FamilyGuy'' episode "Welcome Back, Carter", three skinny girls press themselves together for a group photo and suddenly merge to create one fat girl.
* In the ''WesternAnimation/RegularShow'' episode "Video Game Wizards", when Mordecai tells Rigby that playing with his best friend is more important than winning a video game tournament, they're greeted by a spiritual version of the Power Glove [[BlandNameProduct knockoff]] they're competing for, who for their realization mixes them into a muscular two-headed, four-armed being with Rigby's body and Mordecai's head, arms and right leg. They proceed to easily defeat the team they're playing against before going back to normal.
* In ''WesternAnimation/TheRealGhostbusters'' episode "The Slob", the Sleaze and his brother the Glob were able to merge into a more powerful ghost called the Slob. This proved to be a problem because it was almost impossible to trap them when they were in Slob mode. In the end, they have Professor Dweeb pretend to have captured Slimer in order to lure out the Sleaze so that the two would become separate ghosts again and therefore possible to trap individually.
* ''WesternAnimation/MiraculousLadybug'':
** The titular magic items are an example of the Power Booster type. The kwami apparently disappears, granting its human partner assorted superpowers, a costume, and some special equipment. They can then further fuse with other kwamis, but it has been stated to be psychologically dangerous to overdo (Marinette got a little disoriented just by ''wearing'' a bunch of Miraculouses at once, even without transforming with all of them.)
** It's revealed in season 3 that multiple people holding the same object can be akumatized into a single villain. Oblivio is a fusion of [[spoiler:Nino and Alya]], and Heart Hunter is one of André and Audrey Bourgeois.
** In season 4, [[spoiler:after fixing the Peacock Miraculous, Hawk Moth uses it with the Butterfly Miraculous to become Shadow Moth]].
* In ''WesternAnimation/{{Mixels}}'', the eponymous Mixels are capable of doing this with any other Mixel under virtually any circumstances. The series thrives on this, with at least two Mixels combining in almost every episode. Always of the Power Booster or Composite variety (with the latter dreaded, as it tends to cause more harm than good).
* In the ''WesternAnimation/{{Futurama}}'' episode "Murder on the Planet Express," Fry winds up wearing Bender's metal shell like a suit of armor after the former loses his helmet and the latter his gyroscope, solving both of their problems. Both seem to have an equal amount of physical control over the result, which looks like a combination of both of them and even gets a SpeakInUnison moment.
-->'''Bender:''' Let's call ourselves "Frender"!

* In ''WesternAnimation/StevenUniverse'', any Gem is able to perform Fusion by [[MagicDance literally dancing]], though it isn't actually strictly necessary; it's simply a way of expressing oneself while also participating in a partnership. Fusion can naturally occur when physically close in a crisis, as the minds synchronize. Pearl and Amethyst can Fuse into the serene Opal, Garnet and Amethyst can Fuse into the destructive Sugilite, Garnet and Pearl can Fuse into the showy Sardonyx, and all three can combine to form Alexandrite; any member of their species can also combine with each other. Fusion is treated as an intimate act based highly on the personalities on the Gems involved. Fusions also tend to be large in comparison to the sum of their component Gems. Whether the components Gems' personalities fuse along with their forms seems to vary depending on the component Gems and the product.

** Malachite demonstrates the individuals sharing the body; her components hate each other and fight for control the entire time they're Fused, leaving little to no room for Malachite to actually develop her own personality.

** While not actually resulting in a fusion, Book 3 had an episode where Aang and [[spoiler:Zuko]] perform a firebending "form" that very much resembled the ''DBZ'' fusion dance at several points and was called the "Dance of the Dragons." One humorous fanmade sketch shows [[http://street-angel.deviantart.com/art/ZukAang-Chapter-13-SPOILERS-73949169 the result of said fusion.]] This is likely a ShoutOut, since the show creators are anime fans.

** Malachite demonstrates the individuals sharing the body; her components hated each other and were fighting for control the entire time they were Fused, leaving little to no room for Malachite to actually develop her own personality.

** "Keeping It Together" reveals that the Homeworld Gems have also attempted alternate methods of Fusion, by way of [[spoiler:[[AndIMustScream forcibly Fusing shards of shattered Gems together]], creating [[ArtificialZombie monstrous, screaming results]]]]. The test subjects in question were (mostly) ''[[spoiler:[[CondemnedContestant fallen Crystal Gems from the war]]]]'' [[spoiler:which were incubating under the Kindergarten for at least 5,000 years]]. Garnet describes the results as a perversion of everything Fusion stands for.
** "The Answer" reveals that traditionally on the Homeworld, Gems only fused with Gems of the same type (as seen when three Rubies Fuse into one big Ruby). Fusion between two different types of Gems was seen as scandalous, and an affront to Homeworld's FantasticCasteSystem [[spoiler:as demonstrated when Sapphire and Ruby end up accidentally Fusing together into Garnet for the first time, to the outrage of all the other Gems in Blue Diamond's court.]] Even then, Gems of the same type only ever Fused for combat, not really having time to explore how their Fusions affected their personalities or their relationships with one another. Ruby only felt as though her Fusion with the rest of her squad was just a bigger version of herself, despite her and the other Rubies indeed having distinct personalities.

** "Off Colors" reveals more Fused Gems who have become pariahs and outlaws in Homeworld society: Rhodonite, a highly-stressed fusion of a Ruby and a Pearl who fell in love and were ostracized and replaced by their Morganite master, and Fluorite, a six-Gem polyamorous Fusion who is open to adding more to themselves if that Gem is emotionally compatible.
