History Main / RomanticFusion

** The first is Oblivio who is made from Alya and Nino. They share a glowing purple body, SpeakInUnison and can make people forget things.
** The second is Heart Hunter who is made from Andre and Audrey Bourgeois. They turn into a giant pink balloon monster and consume every form of love they can find.

%% This list of examples has been alphabetized. Please add your example in the proper place. Thanks!

** Stevonnie, the Fusion of Steven and Connie, is first formed by accident when they share a romantic dance. The two rather enjoy being Fused, except for the fact that it means they've literally become one and the same person without another person to depend on, and thus are "Alone Together" (the title of Stevonnie's debut episode).

* In ''Fanfic/TheSoulmateTimeline'', [[spoiler:a [[LegacyCharacter Walpurgisnacht]] is what happens when the Witches in a [[SoulmateAU Soulbond]] of Magical Girls are born and then [[FusionDance fuse together]] into a single entity of cataclysmic destruction. Given the members of a Soulbond are romantically linked, this makes a Walpurgisnacht essentially their EvilCounterpart, and some of Mami's Witchself Candeloro's musings have her make mention of how badly she wants to "become one" with Homulilly (Homura), Kriemheld Gretchen (Madoka), Oktavia (Sayaka), and Ophelia (Kyoko) until they can't tell where they begin and end anymore.]]

* While it was never explicitly made canon, in ''VideoGame/TalesOfZestiria'' Mikleo fulfills all the romantic tropes for protagonist Sorey. He’s also the first seraph that Sorey [[FusionDance armatizes]] with in game, and is by far the easiest.

* ''Webcomic/KillSixBillionDemons'': Allison and Cio do this in ''King of Swords'', becoming what is known in-universe as a Devil-Skin Warrior. Normally, Devil-Skin Warriors lead to conflicts between the two parts and either the devil or the human dominating (which breaks the fusion or kills the human), but Allison and Cio being involved means they are able to syncronize their soul-flames perfectly and work together. [[spoiler:They later add White Chain to it during ''Breaker of Infinities'' in some not-so-subtle ThreesomeSubtext.]]

* In ''ComicBook/ChaosWar'': ''[[ComicBook/TheMightyThor Thor]]'' #2, after apparently losing his powers, Thor’s human alter ego, Donald Blake, merges with his love interest Becca Steinhardt to become Thor once again.
* In ''ComicBook/{{Firestorm|DCComics}}'', Jason Rusch and his girlfriend Gehenna gained the ability to merge into the eponymous hero. This was treated with very romantic (and sometimes sexual) undertones between the two.

* In ''ComicBook/UltimateXmen'', a dying ComicBook/{{Gambit}} asks ComicBook/{{Rogue}} to permanently absorb his mind so that they'll be together. Though Rogue later [[HerHeartWillGoOn moves on with her life and starts new relationships]], she acknowledges that Gambit is still part of her, although in her case she's not quite sure if it's a pleasant experience or not.

* ''{{Manga/Black Clover}}'' has Yuno and his spirit companion Sylph who fuse together to enter the ‘Spirit Dive’ state. While Yuno sees his relationship with Sylph as purely platonic. Sylph is clearly infatuated with him, asking him to take her out on dates and becoming jealously protective whenever another woman is nearby.
* In ''{{Manga/Hellsing}}'', the vampire Seras and Pip Bernadotte have significant romantic tension. When the latter is mortally wounded, he ends up having his soul merged with the fully awakened Seras when he allows her to drink his blood, resulting in him becoming her familiar. While he usually exists inside her and can talk mentally with her he can also be manifested at any time she wills it.

* ''Literature/{{Kanokon}}'' has Koutai, a human and Chizuru, a kitsune youkai in a romantic relationship fuse via kissing and later strong bonds of love into a male kitsune with Koutai's body and Chizuru's mind controlling it.
* ''Manga/{{Phoenix}}: Resurrection'' involves a human named Leon and an industrial robot named Chihiro whom he falls in love with due to a malfunctioning cybernetic brain implant that causes him to see her as a beautiful woman being combined together into a larger robot called Robita, of whom Dr. Saruta's RobotBuddy from the second ([[AnachronicOrder chronologically later]] volume), ''Future'' is a mass-produced copy.

* In ''ComicBook/UltimateXmen'', a dying ComicBook/{{Gambit}} asks ComicBook/{{Rogue}} to permanently absorb his mind so that they'll be together. Though Rogue later [[HerHeartWillGoOn moves on with her life and starts new relationships]], she acknowledges that Gambit is still part of her, although in her case she's not quite sure if it's a pleasant experience or not.

* A few ''Anime/NeonGenesisEvangelion'' [[https://www.fanfiction.net/s/960637/1/Only-In-Your-Eyes-Am-I-Worthy fan]] [[https://www.fanfiction.net/s/4510497/1/Neon-Genesis-Evangelion-Redux fictions]] depicting a romance between Shinji and Rei would feature a scene where the two merge into one being, likely inspired by the scenes in ''The End Of Evangelion'' such as [[spoiler:Rei merging with Lilith and Shinji being fused with Rei in a sexual position during the Instrumentality]]. Due to Rei's nature [[spoiler:as part-Angel via Lilith]], the merging of the two often creates a god-like being powerful enough to start [[TheEndOfTheWorldAsWeKnowIt the Third Impact]] under their terms.
* In ''Fanfic/EquestriaAcrossTheMultiverse'', the Mane Six visit a universe where the native ponies can perform a FusionDance ''WesternAnimation/StevenUniverse'' style. Their first indication things are like this is seeing Mr. and Mrs. Cake walk by in their fused state, though it's unclear if they're permanently fused or not. Supplemental materials reveal this is rather common in this universe.
* In ''Fanfic/DekiruTheFusionHero'', Izuku's absorption quirk allows him to "absorb" people, temporarily fusing with them. The second person he fuses with is his ImpliedLoveInterest Ochako. The resulting fusion not only has the One for All, but Ochako's Zero Gravity Quirk is enhanced so it can also control the movement of anything under its effects.

* In ''Film/TheFly1986'', the concept is brought up in the climax: [[spoiler: Seth, deranged and desperate to retain ''some'' of his humanity as his transformation into Brundlefly nears its endpoint, formulates a plan to genetically merge himself with a "pure" human. When he learns his lover Veronica is pregnant but doesn't want to bear a possibly-mutant child, he kidnaps her and decides she'll be that human. His last lines -- just before he's rendered TheSpeechless by his OneWingedAngel transformation -- have him declaring "We'll be the ultimate family!...More human than I am alone!" Veronica's ex-lover manages to rescue her from this fate]].

* In ''Literature/TheGodsThemselves'' the three-gendered semi-tangible aliens from a parallel universe, known as the Soft Ones, reproduce by temporarily merging their bodies [[spoiler: into a single solid mature entity, the Hard One. The final "melding" is permanent]].

* ''{{Music/Vocaloid}}'': The song "Let's Go to Heaven" describes two lovers committing suicide and their spirits merging to become a single being.

* In ''Franchise/ShinMegamiTensei'', you can have Hindu god Shiva and his wife Parvati as {{Mon}}s in your party. In many games, fusing both of them will result in the demon Ardha, who is basically Shiva and Parvati combined together (as mentioned above in Mythology & Religion). This is also usually the only way to get Ardha in your party.
** Near the end of ''VideoGame/DigitalDevilSaga'', [[spoiler: Serph and Sera]] died but their souls fused, forming the intersex [[spoiler: Seraph]]. Futhermore, their Atma Avatar is Ardha.

* ''VideoGame/MassEffectAndromeda'': Like most asari, Peebee uses her MindMeld on Ryder during sex. But the game shows it much more clearly this time and demonstrates that the meld sends them into a peaceful MentalWorld, where two of them are alone and their thoughts are merged. Based on their reaction, it's one of the most intense and pleasurable acts either have experienced.

* While it was never explicitly made canon, in ''VideoGame/TalesOfZestiria'' Mikleo fulfills all the romantic tropes for protagonist Sorey. He’s also the first seraph that Sorey [[FusionDance armatizes]] with in game, and is by far the easiest.

* ''VideoGame/{{Aquaria}}'': [[PlayerCharacter Naija's]] Dual Form merges her with [[LoveInterest Li]] into a single entity. Said form can switch between the Li side, which can blast enemies to absorb power, and the Naija side, which can unleash the absorbed power in a SonicScream.
* ''VideoGame/VoltageFighterGowcaizer'': Ryo and Suzu Asahina fuse together in their Kaizer Form to create the sub-boss Platonic Twins where Ryo becomes the arms, shoulders, legs, and head or Suzu is suspended in the centre as a torso and arms. Despite the boss name having "Platonic" in this is still an [[BrotherSisterIncest example of a couple fusion]] (at least according to the OriginalVideoAnimation adaptation) and therefore is also a SiblingFusion.

-->'''Planet Express Ship:''' If you really wanted to be with me, you'd merge your programming with mine.
-->'''Bender:''' ''Whoa!'' Whoa, whoa, slow down. All my friends who've done that say that afterwards, all the passion went out of their relationship.

--->'''Steven:''' "Garnet ''is'' a relationship."

* Kelly and Tad from ''WesternAnimation/StarVsTheForcesOfEvil'' are a fairly silly example: Kelly most looks human except she has very long, voluminous hair that resembles a bush. Her boyfriend Tad essentially ''is'' a bush, and spends most of their appearance together sitting on her head, appearing to merge with her hair.

Compare MentalAffair, in which two or more people engage in psychic sex (and thus literally plays up the sexual aspect of Romantic Fusion); and MindlinkMates, where {{Love Interest}}s are connected by a PsychicLink.

-->-- ''VideoGame/FireEmblemThreeHouses''[[labelnote:*]]On the Crimson Flower route, Sothis instead says "The stone within your chest... It is no more."[[/labelnote]]

* ''LightNovel/{{Kanokon}}'' has Koutai, a human and Chizuru, a kitsune youkai in a romantic relationship fuse via kissing and later strong bonds of love into a male kitsune with Koutai's body and Chizuru's mind controlling it.

** ''Anime/YuGiOhGX'': Juudai and Yubel. Juudai swore in his [[ReincarnationRomance first life]] to [[OneTrueLove love them forever]], and not only did they hold him to it, but he held himself to it... once he got around to remembering he'd made the promise in the first place. They end up permanently fusing into one being, which basically amounts to Yubel living in Juudai's mind and giving him access to their powers.

* ''VideoGame/XenobladeChronicles3'': Each of the main characters can "interlink" with one other, creating an Ouroboros form. This form allows each other to see memories and desires of each other, bringing them closer together as people. Noah and Mio are explicitly romantic, and [[spoiler:their {{Evil Twin}}s N and M never interlink despite still having the ability, representing their suffering relationship]]. The other two pairs--Eunie and Taion, Lanz and Sena--can also interlink and merge into an Ouroboros form, but [[AlternateCharacterInterpretation whether their relationships are romantic or platonic are a constant source of debate]].

* ''VideoGame/VoltageFighterGowcaizer'': Ryo and Suzu Asahina fuse together in their Kaizer Form to create the sub-boss Platonic Twins where Ryo becomes the arms, shoulders, legs, and head or Suzu is suspended in the centre as a torso and arms. Despite the boss name having "Platonic" in this is still an [[BrotherSisterIncest example of a couple fusion]] (at least according to the OriginalVideoAnimation adapation) and therefore is also a SiblingFusion.

* ''VideoGame/XenobladeChronicles3'': Noah and Mio, and Eunie and Taion interlink to form an Ouruborus form. This form allows each other to see memories and desires of each other, bringing them closer together as people. Lanz and Sena also interlink and merge into an Ouruborus form, but their relationship is purely platonic.

* ''WesternAnimation/StevenUniverse'' is likely the TropeCodifier, featuring multiple Fusions made of love:

* A rather horrifying example happens in ''VideoGame/LibraryOfRuina'' with Tomerry, a young couple who combined into a hulking amalgamation of flesh. They're barely recognizable as human by the time you fight them.

* ''Wiki/SCPFoundation'': [[http://www.scp-wiki.net/scp-2989 SCP-2989]] is a pair of caterpillars that are constantly traveling through time and space, trying to find each other and leaving poetry behind in their wake. At the end of the entry, the two finally arrive at the same point in time and space, rush to each other, and fuse into a single chrysalis. After eight days, the chrysalis hatches, revealing a butterfly that matches the description of no known butterfly species. It produces the word "WHOLE" in fifty-three languages before moving to an unknown point in space-time.
