Go To

  • Though it contains more than 2 beings, Crash Bandicoot: The Huge Adventure gives a composite form of all the game's bosses which you must run away from in a "true" final level (while avoiding freighter's worth of Nitro Crates, to boot). This ending can be unlocked if the player has gathered all the gems and relics in addition to the Crystals, naturally.
  • Puzzle & Dragons lets you fuse several Mons together, usually three to five at once. These fusions let your mon evolve into a stronger new form, with the evolution usually not similar at all to the mons you chose to fuse it with. Power Booster.

  • Blue Dragon has Ultimate Szabo, which is all five Demon King Robots at once.
  • Several occurrences of this appear in the Breath of Fire series:
    • The first game has Karn, whose only "power" is his ability to fuse with other party members to create powerful fused forms. The power is entirely missable, which can make Karn entirely useless. He gets a form which can only be used underwater after the only underwater section in the game has finished.
    • Ryu's Infinity Plus One Dragon in the first game also allows him to absorb all his partners to form one giant dragon with physical features from all of them. It always does maximum damage with every attack, making most bosses a breeze.
    • The two bosses Balio and Sunder from Breath of Fire III perform their own fusion to fight the protagonists. Ironically, it's the only defeatable form; all but one of its attacks are toned down versions of attacks the two had separately, and it can only perform one attack per turn versus two for the two separately. Ouch. Its appearance is also a major Shout-Out to Ultraman, complete with an energy beam performed with the distinctive L arm pose.
      • There's also a Miracle gene and Tiamat form in BoF3, which allows replaces the party with one gigantic dragon. (The Fusion gene might seem like an example, but Ryu never absorbs other party members when using it; he just copies their attributes.)

    • In Breath of Fire II, powering up your teammates takes the form of fusing them with different elemental Shamans. This can have minor effects (turning Sten's fur red) to major effects (changing the nigh-Joke Character Jean into one of the game's most powerful characters).
  • At the end of Darkstalkers 3, Lilith fuses with Morrigan as a Power Booster. Lilith was originally part of Morrigan, split off precisely because their combined form was strong enough to threaten dimensions and the established order. Due to the time they spent apart, they still got more powerful, by being able to split in order to do two-pronged attacks.
  • Near the end of Legacy of Kain Defiance, Kain and Raziel do the Power Boost version.
  • In Princess Waltz Protagonist perform composite fusion twominds/onebody with one of six other characters to create "Sword Princess Iris" who always looks the same except her dress colour (which depends on a character main hero fuses with). He also often comments on how Iris feels Taller or Faster depending on fusion partner. Game has pretty straight storyline, so no matter which one of 5 6 Chris is a girl too girls you chose, you always end up with Chris as Main "Wife" and others as lesser harem
  • In the Mega Man (Classic) series, Mega Man and Bass can perform a Power Booster fusion with their respective canine companions (far more often for Bass, Mega Man only did it in 6 and 7).
    • Soul Unison (DoubleSoul) in Mega Man Battle Network. It allows MegaMan.EXE to (Composite) fuse with other Navis and gain some of their abilities.
    • A special type of fusion occurs at the end of Battle Network 3 when Lan digitizes himself and merges with Mega Man to boost their response time. This eventually allows synchronization in subsequent games: when MegaMan.EXE scores a counter hit or is performing well, he becomes more powerful as a result of being "in sync" with Lan. But when he performs badly, he becomes more vulnerable as a result of being "out of sync".
      • Taken further in Battle Network 6, where MegaMan can use "Beast Out" to (Composite) fuse with the Cyber Beast he has sealed inside of him, which also has a touch of Two in One Body as if MegaMan is mentally exhausted, he can make one last pull, but temporarily loses himself to the Beast's power, and afterwards is left fatally weakened, or take the characteristics of an allied Navi (another composite), or reap the benefits of being "In Sync" with Lan (see above). And yes, you can have two of these at once; sadly, you can't be in "FullSync" and in a "Cross" (the Navi fusion) at the same time, making MegaMan absurdly powerful with the right combination of chips and programs.
    • In Mega Man Star Force, the hero(es) use(s) a combo composite/switcher. Geo lives his life normally until the baddies attack, and then he turns into the "Mega Man" of the series, which involves fusing him with energy being alien Omega-Xis.
      • He can also take the powers of other Energy Beings to gain additional powers. It's even possible to have what could be considered a four-way fusion in the third game.
    • Mega Man X had a few characters who could join together as Composites; for example, Bit and Byte of X3, who become Godkarmamachine O Inary.
    • Mega Man ZX has Biometals (Livemetals in the Japanese version), which contain the souls of characters from Mega Man Zero and X. The Biometals act as a Power Booster for humans and Reploids, turning them into "Mega Men" and granting them armored forms and abilities.
      • This Power Boosting system also has a Composite function; once the player finds both the Model X and Model Z Biometals, they can fuse with both at the same time to become Model ZX in what's called Double Megamerging. The titular transformation is only one of the six Double Megamerges (out of seven forms). (In the sequel, the player only has a single Biometal—Model A—that can copy the forms of other characters and Biometals without actually fusing with them).
  • Every Golden Sun game ends with one of these as the final boss.
    • The Fusion Dragon is a fusion of Saturos and Menardi.
    • The Doom Dragon uses Felix's parents and Isaac's dad. The player character shows remarkably little grief over it... Must be a Heroic Mime thing.
    • The Chaos Chimera uses Blados, Chalis, and the Chaos Hound as its components. Tear Jerker ensues as the latter turns out to be Volechek, and forcibly fights his sister and her companions again.
  • In Starcraft, two Protoss Templars can fuse into a single, ultra-powerful 'Archon' unit. It is a one-way process, and falls outside the three main types, since the brutal martial prowess of the Archon is quite different from the casting abilities possessed by the Templars. It's explained that, while Templar are very powerful with directed psychic abilities, Archons are the embodiment of raw psychic energy.
    • The process is inverted by the martially-deadly Dark Templars that can merge to form a Dark Archon - which have a few very powerful "spells", but are completely useless in battle when they're low on mana.
    • In Starcraft 2, both the Dark Archons and the announced Twilight Archons were ditched and now any combination of templars results in a conventional Archon. The In-Universe reason being that the Dark Archons are the result of a Dangerous Forbidden Technique and far too powerful (one by the name of Ulrezaj goes nuts and is a big-time villain in the novels).
    • The third expansion pack features Archon Mode, where two players run the same base and army.
  • In Soul Nomad & the World Eaters, the main character is the 'victim' of a botched Demonic Possession by Omnicidal Maniac ex-Big Bad Gig, which ends with the two Sharing a Body and Gig effectively becoming the main character's Power Booster on a permanent basis. It has the side effects that Gig isn't exactly the most pleasant being to coexist with—and that drawing too much on his power will complete the possession to a manner more to his liking.
  • In all the Disgaea games, monster-type enemies can be merged by throwing them together—effectively a Power Booster, in that the fused being is the highest-leveled component monster with a boost in levels equal to the level of the weaker monster. Disgaea 3 also had the Magichange ability, which enables a monster to temporarily transform into a weapon for a human character, which enters into this trope mainly for those that turn into Fist-type weapons. (In all cases, the Magichanged monster provides both its main ability, and a percentage of its stats, to the wielder—but for most non-Fist versions, it more closely resembles an Empathic Weapon.)
    • Expanded on in Disgaea 4, where a monster can do a Fusion Dance with another one to supersize it, giving it increased stats across the board, and an increased range/radius on its attacks, among other things. It can still magichange in this state, as well, which gives a humanoid a ridiculously huge weapon that increases the range and radius of all their skills, ontop of the usual magichange benefits.
  • In Dragon Quest Monsters, you breed Mons together, the results of which are frequently a Fusion—especially when dealing with the Slime. For example, breeding a Slime (looks like a blue hershey's kiss) and a Golem (looks like a man made out of bricks) gets you a Rockslime, which looks like a Hershey's kiss made out of Bricks.
    • Later localizations Enforced this trope by renaming this mechanic to synthesis, possibly because they wanted to avoid people thinking about the details on just how the copulation happens.
  • In Lunar Knights, Lucian and Aaron can merge with the dark and light terrenials, respectively, to enter a more powerful form, although it has a fairly short duration.
  • In Persona 3, the Main Character can create new Personae by fusing two or more existing Personae together. The new Persona can inherit attacks from any or all of its "parents" (including some that it wouldn't learn naturally).
    • The original Persona allows the main character to do something similar, but using cards containing the essence of demons.
    • Most of the other games in the Shin Megami Tensei series let you fuse demons directly; in the continuity comprising 1, 2, If... and Imagine, it's All There in the Manual (and visually explicit in Imagine) that this effectively kills the original demons in the process.
      • In Shin Megami Tensei III: Nocturne, there are standard fusions and "sacrifice fusions." Entering a certain door with either the first pixie who joined you or a demon made by fusing her will cause that demon to transform back into the original pixie with boosted stats and powers. Using the pixie as a sacrifice will not let you trigger the scene, suggesting that using a demon as a sacrifice will kill them, but regular fusion, not so much.
    • In Shin Megami Tensei II, it is explained that Satan is the result of a fusion between the demon Seth and a specific human. It is later revealed that the human is your ally Zayin. You cannot stop the fusion, and on the Law route, you'll want the fusion to happen.
    • Rather brutally explored in Shin Megami Tensei: Strange Journey: Jack's Squad, who didn't get the Demon Fusion program, are trying to work out the methods themselves... through horrible experiments on captive demons. (One captive begs for the return of its hands and feet.) They're trying to fuse humans with the demons, and judging by the hideous demons you fight in their HQ, the results are not anything good. And then there's what happens with Jimenez...
    • In Shin Megami Tensei IV, Jonathan fuses with the Archangels to form Merkabah. Walter also fuses with Lucifer, but this only restores Lucifer's true powers. In Shin Megami Tensei IV: Apocalypse, two major instances occur near the end of the game: Krishna fuses with Flynn to become Vishnuflynn, and Merkabah and Lucifer refuse to become Satan.
    • Shin Megami Tensei V will once again feature the demon fusion mechanic, as usual for the series.
    • In Digital Devil Saga, the lead male and female, Serph and Sera, fuse into one ultimate being named Seraph; while the result is mostly controlled by Sera due to Serph being a Heroic Mime, it is stated their minds would eventually merge the same way. This is explicitly a reference to the Hindu religion, where the perfect being is said to be a fusion of both the female and male aspect. An example in Hinduism is Ardha, the fusion of the Shiva and his wife Parvati. This may not apply to all sects of Hinduism though; being Older Than Dirt, Hinduism has so many different sects and interpretations that your head will explode trying to figure out the contradictions.
    • Devil Survivor heavily features the usual series mainstay of fusing demons together, but also has a rather bizarre offhand reference when fusing the demon Lilith with another.... wherein she will pout and state that she would much rather try fusing with you. It's unclear whether she was just going for a little Double Entendre, or if this is actually possible in the game's universe.
  • In Star Control II, the Mmrnmhrm (a mechanical sapient race) and the Chenjesu (a crystalline race) are eventually discovered to have merged into a gestalt composite race, the Chmmr. Once they join your alliance, they are able to provide you some small assistance with your combat capabilities. Notably, the fusion process would have taken several decades but, since none of you have that much time (the Ur-Quan Kor-Ah will be on their genocidal warpath much sooner than that), you're forced to speed it up. They imply this ended with an imperfect, incomplete fusion and question you about it, but brush it off quickly because of the aforementioned time problem.
  • Masa and Mune in Chrono Trigger fuse after getting their individual butts kicked while testing potentials to wield the Masamune. The result is pretty... chubby, for some reason.
    • Obviously, their fingertips were misaligned.
      • Makes you wonder how powerful they'd be if they got the fusion dance right.
    • Dream, or Doreen, merges with them in Chrono Cross. They all inhabit the "Grand Dream," or Mastermune.
    • The Time Devourer of Chrono Cross is a Composite fusion of Lavos and Schala, whose disapproval at the notion of Might Makes Right Evolutionary theory has her tell the entire space-time continuum/multiverse that it had better find some other way of defeating Lavos, or she'll erase everything. Granted, she's affected by Lavos' destructive intent.
      • We also see Harle, the Seventh Dragon, doing the Fusion Dance with the other six dragons.
  • Some Slimes in the Dragon Quest series can band together to form a King Slime. You can tell right away that they're different from garden-variety Slimes because they take slightly more damage than normal, and they always call for help.
  • For most of Illusion of Gaia, Will is a Switcher: he lives the normal life, but he can take the form of the Dark Knight Freedan or the Light Knight Shadow (don't ask) when he explores dungeons. At the very end of the game, however, he performs a Composite fusion with Kara, another fully evolved human and the new Light Knight, to become a super-powered version of Shadow, complete with a new "Firebird" attack.
  • The main premise of the old NES game Monster Party was that Mark, a kid with a baseball bat, and Bert, a flying gargoyle dragon thing, fused together to fight monsters in the Bert's home, the Dark World. Most of the game is played as Mark, who only transforms to Bert when he scoffs down pills that are just lying around. It is a mystery why Bert needed Mark, since the Bert form is entirely superior.
  • Marathon gives us an example with two non-physical characters. Near the end of Infinity, the player character merges his AI With An Internet Connection Durandal with the ancient alien AI Thoth. The resulting character is a Composite of the two, although thankfully he doesn't seem to posess some of the traits of Durandal or Thoth.
  • Kingdom Hearts:
    • In Kingdom Hearts II, Sora can use his party members as Power Boosters using the Drive System. For example, Sora's Dual Wielding Valor Form involves absorbing Goofy. Absorbing Donald turns him into the magic-oriented Wisdom Form. Absorbing both active party members can turn him into Master or, later on, Final Form.
    • In Dream Drop Distance, Riku can use Dream Eaters as a Power Booster and enter various "Link Styles". The fact that Riku can do this and Sora can't is Foreshadowing that Riku is a Dream Eater in this game.
  • The Legend of Zelda:
  • In the Touhou series, Utsuho Reiuji (a hell raven youkai) received a Power Booster of sorts by eating the body of a yatagarasu (a divine sun crow), as directed by another goddess, Kanako Yasaka. As a result, she now has power over nuclear fission and fusion, and her body has changed somewhat as well - she now has the yatagarasu's third eye on her chest, a control rod (the "yatagarasu's third leg") on her arm, and "feet of fission and fusion".
    Utsuho Reiuji: The ultimate energy is nuclear fusion power! Won't you fuse with me?
    • The Touhou fandom seems to like making Utsuho herself an unwitting Power Booster for others, such as Mokou Fujiwara, Nitori Kawashiro, and Tenshi Hinanai. Becoming a part of someone else, rather than them becoming a part of her, is probably not what Utsuho had in mind ...
    • And then there's Utsuho's actual Fusion Dance.
  • For the Final Boss of Tomb Raider: Legend, Amanda merges with the Unknown Entity.
  • This is how each of the power-ups work in Sonic Colors — Sonic merges with the Wisp to gain its powers. They reappeared in Sonic Lost World, filling the same purpose as they did in Colors. However, in Sonic Forces, they are instead being fused with a gadget called a Wispon.
  • The final boss of Tron 2.0 is a monster formed from the three main antagonists after their botched attempt to digitalize themselves.
  • The entire point of Trine is that the three main heroes become a Switcher single main hero due to the titular artifact.
  • In Freedom Force, a blind female witness and an idealistic rookie cop get hit by Energy X and merge into a switchable superhero named Law and Order. The witness becomes Law, who is appropriately blind, and is armed with a sword. The cop becomes Order and is armed with a massive gavel. Only one can exist at any given time.
  • Similar to the Starcraft example, the Viron units in Ground Control II are able to merge into other units, although the new units are not necessarily more powerful. Unlike Starcraft, this process is reversible, making Virons pretty versatile.
  • In Pocky & Rocky 2, Pocky can use Magic to fuse with her partners as a Power Booster (though there are a couple she just rides instead).
  • In Dragon Age non-demonic spirits who possess a mortal seem to be Switcher/incomplete Composite types. They're always present in mind, and their personalities do influence the other, but the spirit can also take over. In Wynne's case, the spirit of Faith only takes over briefly to protect her with healing and buffs. Anders is a gifted healer who switches mode to deal the more powerful offensive magic that only Vengeance is capable of. Sometimes Vengeance appears to seize control against Anders' will.
  • In the Fallout series, creatures called Centaurs are made by putting more than one creature into a vat of the Forced Evolutionary Virus. The results are not pretty.
  • In Little Fighter 2, Firen and Freeze can merge into the super-powered Firzen, but only one player gets to control him, so the other has to sit out until they decombine.
  • The gameplay of Illusions involves merging and splitting amoeba-like creatures called Gleebs.
  • The obscure 1989 Namco shmup Dangerous Seed has an example in the last three bosses before the final stage. Allowing the st. 5 or st. 6 bosses to escape leads you to a different planetary orbit, with a boss consisting of a mashup of the boss who escaped and the boss who you'd normally fight there. What makes this really interesting is that if you allow Multi-Squid (st. 5) to escape, then let its fusion with Shark-Mouth, Monster-Head, escape the next boss fight, the new seventh boss, Ultimate-Tiger, is a Monster-Head/Twin-Claw fusion. In other words, it's three bosses fused together. Have fun!
  • Salazar in Resident Evil 4 fuses with the Queen Plaga and a Verdugo to form the Chapter 4 boss.
  • Pokémon:
    • From Pokémon Black 2 and White 2 onwards, Kyurem can become Black Kyurem by merging with Zekrom, and become White Kyurem by merging with Zekrom's other half, Reshiram. It can do this due to being a byproduct of Zekrom and Reshiram splitting from their original form (i.e., the original dragon split into Zekrom and Reshiram, and Kyurem is the 'husk' that was left behind). The DNA Splicers let the player do this (and reverse the process) at any time, so long as both are in their party.
    • Zygarde is made up of several Zygarde Cores and many more Zygarde Cells. While it remains in its 50% Forme, it's able to merge with all its components in dire situations to achieve its Complete Forme.
    • A rare human example in Pokémon Sun and Moon can be seen with Lusamine and Nihilego during the climax. Lusamine willingly fuses herself with Nihilego in order to defeat the main character once and for all. Upon her defeat, she tries to personally kill her daughter, Lillie, but Solgaleo/Lunala (depending on the version) arrives and defuses the pair.
    • Another (much more bizarre) human example occurs in Omega Ruby and Alpha Sapphire. In an All Your Powers Combined version, the guys who hand out O-Powers in Mauville City perform an event where they circle around another man who lives in an apartment nearby and merge with him one by one, eventually forming Mr. Bonding from Pokémon X and Y.
    • In Pokémon Ultra Sun and Ultra Moon, Necrozma can perform a Grand Theft Me on either Solgaleo or Lunala to form Dusk Mane Necrozma or Dawn Wings Necrozma, respectively, turning Necrozma into some form of armor on the others. From either of these forms, Necrozma can power up further by undergoing a transformation known as Ultra Burst to become Ultra Necrozma.
  • Kinky of Pac-Man Arrangement has the Power Booster form of this ability; being able to merge with any of the four standard ghosts and cause them to double in size and gain a special ability. They're also worth double the points when you eat them.
  • Happens a lot in Mario RPGs. A lot of those also contain Demonic Possession, but the fusing aspect is still there. Often they're final bosses:
    • Both Paper Mario: The Thousand-Year Door and Paper Mario: Sticker Star have Boos joining themselves together to form a bigger, meaner Atomic/Big Boo.
      • The final boss' first form from The Thousand-Year Door is a fusion between Princess Peach and the Shadow Queen.
      • Do not forget the Smorgs.
    • Super Paper Mario, the final boss is a fusion between Dimentio and Luigi, having features from both characters and powered by the Chaos Heart.
    • Mario & Luigi: Superstar Saga has Cackletta taking over Bowser's body after being defeated midway through the game, turning into Bowletta, which is Bowser's body showcasing some of Cackletta's features (including boobs).
    • In Mario & Luigi: Dream Team, when battling in the Dream World, Mario and Dreamy Luigi perform the Power Booster version of this, with Dreamy Luigi becoming a green aura that powers Mario up.
    • Mario & Luigi: Paper Jam, the final boss is a fusion of both Bowser and Paper Bowser called Shiny RoboBowser. Technically speaking, Paper Bowser fuses with a large number of his Mooks to become a giant suit of cardboard armor that the enlarged Bowser wears.
  • In Robopon, the three Zero cyborgs in Robopon 2 do this to attack Cody one more time as he leaves the Pond Garden, creating the multi-faced abomination called Insector.
  • Yu-Gi-Oh! Reshef of Destruction inverts this with Dark Flare Knight. In the real life game, he's a fusion of Dark Magician and Flame Swordsman. In this game, when the Dark Flare Knight is sent to the graveyard, it Comes Back Strong as Mirage Knight, and when the turn ends, he's de-fused into his original two forms. The game itself has no Fusion Monsters.
  • In Pinball Quest, the main enemies of the first table are a set of animated skeletons who combine to form a giant skeleton.
  • Tales of Zestiria Out of the 6 fighters, it lets two characters fuse. Gaining new powerful attacks and a Mystic Arte to go with the new form. This process is called Kamui in Japanese and Armatization in English.
    • Tales of Berseria also has armatization, in a much more unstable and experimental fashion as used by the antagonists. It still gives a human the powers and appearance of a malak counterpart, but it's more like forcing the malak into the human's body, and can kill the user if used improperly. Most of the Mook exorcists end up involuntarily self-destructing after using it. There's also the part where Teresa lets a therion fuse with her so she can attack the party.
  • Done unwillingly by Robin, Frodo, and Metalbeard in LEGO Dimensions to form The Tri.
  • Capella's Promise has the Mother superweapon, whose sole purpose is to combine people and monsters into monstrous soldiers known as Hutes. Worse yet, she can fuse Hutes into even stronger Hutes. The Big Bad of the story, Zanara, ends up fusing with her to create an intelligent but insane war machine.
  • Several crossover games have merged bosses made of up of two characters from the respective franchises being featured:
  • In Cuphead, the two Bash Brothers, Ribby and Croaks, perform their dance during the final phase of their fight, where one swallows the other and they turn into a huge slot machine.
  • In Eternal Fighter Zero, Mai Kawasumi and her ghost partner (Also called Mai) can do a Power Booster version for their Final Memory, called "Awakening": The ghost partner merges with Mai, who gets a boost in offense and speed for several seconds, giving her access to more combos and other powerful moves.
  • The Final Boss of Spider-Man: Edge of Time is a fusion of Doc Ock, Walker Sloan, and Anti-Venom (or Rhino in the Nintendo DS version) that Spider-Man dubs Atrocity.
  • Eternal Twilight has the Blood Council members fuse into a giant red monster known as the Bloody Abomination, which uses similar debuffing mechanics as the original components.
  • In Undertale, monsters can absorb human souls as a Power Booster, and if a monster could absorb seven souls, they would have the power of a god. This is central to the kind King Asgore's plan to free his people, as this power is needed to break the barrier trapping him and his subjects underground (you're the seventh, by the way).
    • In the Neutral Endings, Flowey manages to steal the six previously gathered souls, and would have won, except it turns out to be a mild Two Beings One Body fusion, and the collective six human souls are able to resist enough to forcibly overload Flowey and escape.
  • In Book Four of Dreamfall Chapters, the First Dreamer merges with Zoë, making her the Barrier Maiden.
  • In Grow ver.3, a character made of metal cubes will merge with a similar character made of purple balls when they meet.

How well does it match the trope?
