Merging Machine

Go To

Basically it's a device that fuses multiple objects together, kind of like Fusion Dance. Works by either shooting a beam or placing the objects into a machine. May also work in reverse. Sometimes, the effect is unintentional and probably not the main purpose of the device; Teleporter Accidents are particularly prone to turning the devices into Merging Machines, especially in cases such as Tele-Frag.

May be involved in Item Crafting. This may be the source of Mix-and-Match Critters, Mix-and-Match Man and (sometimes) Ninja Pirate Zombie Robot.

Not to be confused with Combining Mecha.

    Anime & Manga 
  • In JoJo's Bizarre Adventure: JoJolion, the Wall Eyes are a geological phenomenon that have this effect on objects buried in the ground near them. One character demonstrates this by burying a lemon and an orange, then digging them up and cutting them to reveal that they've swapped segments. Later it's revealed that this has nothing to do with the Wall Eyes, and the ground has had this property for generations. It's also responsible for the creation of protagonist Josuke Higashikata, who's the merger of two men, Yoshikage Kira and Josefumi Kujo.
  • Wapol of One Piece had this as one of his sub-powers. While the Munch-Munch Devil Fruit gave him the power to fuse himself with anything he ate, he could also fuse eaten objects with each other, creating an entirely new object. This trope is then exploited as he ends up profitting by promoting the fused objects as toys and selling them.
  • That Time I Got Reincarnated as a Slime: Shizue Izawa possesses the Unique Skill [Degenerate], which allows her to combine and disassemble items or even abilities in her possession at will. However, Shizue was never able to draw out this Skill's full potential before her passing. After absorbing her per her dying request, Rimuru gains the Skill for himself and is able to start making full usage of it with [Great Sage's] help to, among other things, break down weapons and items into natural resources in order to harvest those same resources to make new items, combine minor Spirits into new Spirits that he then fuses with other people, and create new Skills on the fly from existing ones in his possession. [Great Sage] eventually merges with [Degenerate] in order to complete her evolution to the Ultimate Skill [Raphael, Lord of Wisdom], keeping the latter Skill's effects and boosting them even further.

    Comic Books 
  • There was a strip in the 1970s British Comic Whizzer and Chips called "Minnie's Mixer", which played this for laughs. The eponymous device looked like an electric food mixer, but when pointed at two objects in close proximity could fuse them together. Most often used to mix people or pets with objects. Fortunately the process was reversible.
  • A case where the "merging machine" is a person: In the thirteenth issue of Grant Morrison's Animal Man series, the B'wana Beast was infected with Anthrax and it drove him a bit crazy, to the point he was using his powers to merge random animals and turning the resulting chimera into killing machines.

    Films — Live-Action 
  • The Fly (both the 1958 and 1986 versions) is arguably based around an accidental version, merging a man with a fly (and later the man-fly with the teleporter itself). Many parodies and homages tend to fall into this trope by having multiple "mixings" take place.

  • Captain Underpants has the Combine-o-tron 2000, which can bond things like humans and robots together at the cellular level. Its effects can be reversed by putting the batteries in backwards.
  • One of the Gamebooks based off of Super Mario Bros. called "Monster Mix-Up" used this as its primary gimmick. Bowser has a device called the Monster Mixer, which looks like a giant flying egg-beater, that he uses to fuse his minions together into more dangerous troops. The ending has Princess Peach consider unfusing them with a device based upon a soup strainer.

    Live-Action TV 
  • Star Trek: Voyager episode "Tuvix". A transporter accident fuses Tuvok and Neelix together, forming the title character. They eventually work out how to reverse the process, leading to an existential plea from him equating it to murder.
  • Mystery Science Theater 3000: In the "Manos" The Hands of Fate episode, Joel's invention exchange is the Cartuner, a device that takes two newspaper comic strips and combines them into something funnier than the source material.
    "Ziggy had Garfield neutered? Now that's funny!"
  • Inverted and then played straight in one episode of Star Trek: The Original Series, where a transporter malfunction splits Captain Kirk into two people, one with all his more aggressive traits and the other with his more passive traits. Eventually the crew figures out what caused the malfunction and successfully uses the transporter to reunify him.
  • In a failed CBS pilot a scientist developing a teleporter decides to use it to surprise his girlfriend in another lab by teleporting in with a rose and invite her out for a date, but being unfamiliar with the lab he teleports into the same location of an advanced space probe complete with AI and survival instincts she's developing causing them to merge. As a result when he's threatened the probe that's otherwise invisibly merged with him emerges in increasing degrees until when at risk of death it completely takes over looking like a vaguely humanoid killing machine.

  • BIONICLE: The Spear of Fusion, which can also be used in reverse. The results can be a bit unpredictable and can only be undone with the spear. When it was accidently used to split a skakdi in two, the result was one being with the same appearance and abilities as the original but with reduced intelligence and self control and another being that looked completely different and was smarter than the other half but powerless and rather crazy. It has also been used to split a flying creature into two animals that each had only one wing so couldn't fly, fuse together two toa into a creature with reduced intelligence and very different powers than its components, and fuse two skakdi together to form a being that immediately turned on its teammates because it now had twice as much hatred for its team.

    Video Games 
  • Jakyou Manors/The Velvet Room/Demon Fusion Program-enhanced tech in most of the Shin Megami Tensei games, including the Persona series, function this way for combining demons, personae, swords, spell/tarot cards, and any number of other compatible things.
    • There have been cases in which accepted parts for fusions have included humans (twice) and a dog. Most of the time, they remember their pasts. On the other hand, aggression level is raised and there is the question of getting a severe case of violent madness and eventual breakdown; so far, there has not been a single recorded case of a successful demon/human fusion in which the results did not present a form of sanity degeneration, either through obsessive devotion to all laws or complete and utter contempt for all of them, both reaching sociopathic degrees later on. Evil Is Not a Toy, kiddies!
  • In Tymora's Luck tinker gnomes and two gods made a "fusion chamber".
  • Played with in Day of the Tentacle, where, at the end, the three Player Characters have to use a single Chron-O-John to travel through time, chasing the Purple Tentacle. They come out apparently fused into a single monstrosity with three heads. Later, Dr. Fred uses an X-ray machine to scan them, revealing that they're all separate people stuck in a single shirt. Embarrassed, they separate.
  • Mocked in No Time to Explain for the final level. One of the Yous suggests wielding both the beam cannon and the shotgun at the same time to enable a Double Jump, and this is somehow taken by one of the other Yous to fuse that You and Stunt Man You into one being who wields both. The fused character's profile page is even him screaming in agony.
  • In Psychonauts in the Rhombus of Ruin, Raz encounters a device in a crashed alien spaceship that can split and merge objects.
  • Mario + Rabbids Kingdom Battle have The Supa-Merge. A piece of headgear that targets two objects in close proximity and fuses them, resulting in something new. One unfortunate Rabbid ends up fused with it and can't control its ability to fuse things, which results in a lot of the enemies you fight in the game.

    Web Comics 
  • Homestuck's punch-card alchemy process lets you convert objects into punch-card codes and back, and by merging the codes, you can create merged objects.
  • Kid Radd has the Chimera program, which, among other things, can merge individual sprites together. You have to be extremely careful when you set the parameters, however, or things will get ugly.

    Web Original 
  • The SCP Foundation has SCP-914, "The Clockworks". Putting two items in the input booth and running the machine on "fine" (the setting for turning things up a notch) or "very fine" (typically produces something that goes even higher to the input) tends to yield outputs that combine aspects from both inputs; in one of the side-stories, 914 was fed a D-class and a 64-core supercomputer multiple times, with outputs including sixty-four small robot spiders with human faces and a human with a supercomputing brain (which was the desired output). In addition, one of its other settings, "coarse," often functions as an Inversion, separating objects into their component parts.

    Western Animation 
  • The Ace Ventura animated series had an episode based around a scientist whose teleporter combined him with a fly. Later in the episode Ace is combined with Spike.
  • For one episode of Fairly Oddparents Timmy celebrates a half-day from school by wishing up a machine that combines any distinct objects put inside. He has a lot of fun making himself half-kid and half-skateboard, but it goes wrong when Crocker combines himself with cheese and gains cheese-based powers. Timmy has to combine himself with a lot of objects to stop Crocker.
  • ReBoot had an episode where a corrupted game fused Megabyte with a containment unit filled with liquid energy. It turned him into a Megatruck, and the game just happened to be a pastiche of Mad Max 2: The Road Warrior.
  • One Treehouse of Horror episode from The Simpsons, where after Homer buys a matter transporter from Professor Frink (and uses it around the house to save him walking from one room to another... though it takes more effort to move the transporter booths), Bart uses it to fuse with a fly, hoping it will give him superpowers. But instead of Brundlefly, he gets the 1958 Fly (Bart with a fly head, the fly with Bart's).
  • Alpha from the Men in Black series used an alien device called the Cosmic Integrator to grant him the power to fuse alien body parts to himself.
  • One episode of Phineas and Ferb had Dr. Doofenshmirtz build one of these so he could combine his two childhood loves: his pet giant cockroach and garlic ice cream. They go together about as well as it sounds.
  • In one episode of The Adventures of Jimmy Neutron, Boy Genius, Jimmy and Carl's hamster Mr. Wuggles accidentally swap heads after a teleportation experiment gone wrong.
  • Mixels has Cubits, a special ore collected by the Mixels, which allows them to create their Mixes, Maxes, and Murps in the first place. All it takes is at least two Mixels that share the color scheme of the Cubit (or a Rainbow Cubit, which can be used by any tribe in any way), and a single touch from each, and they'll become a new combination. The game Calling All Mixels reveals that Cubits can be used to merge items together as well, mainly to create new Cubit collectors or defense stations for the collectors.
  • Inverted near the start of the Gumby movie, where after Prickle, Goo, and Pokey accidentally fuse themselves into a ball of clay, they get taken to a hospital where a machine is used to separate them. Notably, this entire scene was removed in the Director's Cut version.
  • In one episode of The Secret Saturdays, the Saturdays get tricked by a faked message from a ghost into helping some evil scientists complete a machine that can merge living things together, who then test the machine on Zack, Fisk, and Komodo.
