->''"I can fix it!"''
-->-- '''Fix-It Felix Jr.,''' ''Disney/WreckItRalph''

You want to [[ReversePolarity reverse the polarity]] on your particle defibrillator? Better get it to Mr Fixit quickly.

It doesn't matter if Mr Fixit has never seen it before, has never seen anything like it before, is unfamiliar with its working principles or doesn't even know the stuff the box is made out of; Mr Fixit will be able to reverse engineer it in time for the big finale. He will often possess MachineEmpathy, and can diagnose a broken gadget just by looking at it.

Overlaps with MadScientist, though not all Mr. Fixits are scientists or doctors; some are just avid tinkerers with a lot of free time. Compare WrenchWench. Often overlaps with GadgeteerGenius. Subtrope of TheEngineer. Occasionally keep themselves in work by means of TimTaylorTechnology, which creates more things to fix.

Unrelated to [[Comicbook/IncredibleHulk the Incredible Hulk]], who used the alias "Mr. Fixit" in the late 1980s. And no, this page does not center around the fox in Creator/RichardScarry's Busytown, either.

!!Examples:

[[foldercontrol]]

[[folder: Anime and Manga ]]

* Bulma from ''Manga/DragonBall'' is a clear example. Able to build nearly anything with time and resources. She even took an alien scouter, and within a few hours or days, somehow changed its language from whatever alien space language it used, to Japanese (or English, or whatever language)!
** It should be noted that the scouter did not display a language, only numbers, and deciphering a numbering system is actually very easy to figure out, relative to a language at least. Deciphering an operating system written in a different numbering system and converting it to display a new language... now ''that'' is impressive.
** It's InTheBlood: Bulma's son, Trunks, also has a knack for figuring out alien tech. He was able to repair the alien RobotBuddy Giru with little issue.
* Leeron from ''TengenToppaGurrenLagann'' anyone? [[{{Pun}} Theoretically]], [[spoiler: every device after the timeskip could be his invention, or a descendant of something invented. Yes, one man started his whole planet's industrial revolution.]]
* Presea [[spoiler: and in the anime, her BackupTwin Sierra]] from ''MagicKnightRayearth''.
* Wapourif from ''{{Simoun}}''.
* Yusei Fudo from ''Anime/YuGiOh5Ds'' grew up in the slums of Satellite, but that didn't stop him from teaching himself mechanical, electrical, and computer engineering to the point where he could build his own D-Wheel from the scrap and spare parts tossed away by the people of New Domino... Twice. ([[spoiler: Thrice if you've watched the Japanese version]]) He also made a Duel Board (a skateboard with D-wheel capabilities) just by ''hearing about it'' from Rua...''''in one night''''!
** Also Bruno, who on his first appearance managed to increase the power of the guys' D-Wheels where Yusei couldn't.
* Franky from ''OnePiece''. Usopp as well, especially before Franky joined the crew.
* Winry, from ''Manga/FullmetalAlchemist'', shows the ability to fix most mechanical gadgets and break open locks (sealed with alchemy!) in addition to being a master of fixing automail.
* ''Anime/SpeedRacer'' Lionel "Pops" Racer. He's the one who designed and built the [[CoolCar Mach]] [[SuperRobot 5]].
* On ''Anime/GundamWing'', Howard fixes Duo's Gundam, and makes a living selling scrap metal and refurbishing weapons and the like. Duo learned from him, and (despite his {{Fanon}} reputation as a klutz) is quite an accomplished tinkerer himself.

[[folder: Comic Books ]]

* In TheDCU, the JusticeLeagueInternational often turned to Kilowog of the GreenLantern Corps for all their tech needs. The most extreme example was probably when he built the Club JLI resort on the island of [=KooeyKooeyKooey=] for BoosterGold and BlueBeetle in a matter of hours. In later incarnations of the team, this role was taken by {{Steel}}. Both characters were also {{Genius Bruiser}}s.
** That torch seems to have been passed to BadassNormal Mr. Terrific.
* Taken to the extreme in [[MarvelUniverse Marvel Comics's]] Forge, whose mutant ability helps him build machines by simply imagining what they should do, rather than working out the pesky details.
* Creator/AlanMoore's {{Promethea}} has an unusual example - Stan of the Five Swell Guys is clearly the Mr. Fixit of the team, but Marv claims to be the [[TheSmartGuy team genius]]. This subversion of SuperheroSpeciation becomes a plot-point when [[spoiler:it's revealed that Stan created the team's arch-nemesis, the Painted Doll, due to his resentment of Marv.]]
* ComicBook/DeathsHead's {{Sidekick}} Spratt is pretty competent with a toolbox, and rebuilt Death's Head after he was nearly destroyed by the Dragon's Claws.
* Dino Manolis aka The Machinist of StormwatchPHD excels at this. Too bad, he sucks at most everything else in life.
* Herschel Clay, [[spoiler:aka "Mantium"]], from ''PS238''. As the janitor for a school for [[DifferentlyPoweredIndividual metahumans]], he's (obviously) a metahuman himself and has a love of tinkering. He's also implied to own Clay Industries, which sells most of the inventory, security doodads, and other components of the school and its security system. Exactly why the owner and main braintrust for a (presumably) multinational corporation [[NonIdleRich works as a janitor at a school]] is anyone's guess.

[[folder: Film -- Animation ]]

* Fix-It Felix Jr. from ''Disney/WreckItRalph''.
** In a twist of irony, this actually comes back to bite him [[spoiler: when he is imprisoned in King Candy's castle, any attempts to break the bars on his cell only end up fixing them so that they're stronger than before.]]

[[/folder]]

[[folder: Literature ]]

* [[OurGnomesAreWeirder Tinker Gnomes]] of [[{{Dragonlance}} Krynn]]. Of course it may not work as their non-gnome friends would hope.
** [[spoiler: The Device of Time Journeying in particular could be repaired by any gnome (even one who thinks it's a meat grinder) though it was not mechanical and the parts consisted of pieces of gold, a chain, and a couple thousand gemstones.]]
* As noted above, Creator/RichardScarry's ''Busytown'' books features a recurring character called Mr. Fixit, a fox repairman who can repair anything.

[[/folder]]

[[folder: Live Action TV ]]

* Professor Wickwire from ''Series/TheAdventuresOfBriscoCountyJr.''.
* Seamus Harper (The Engineer) from ''Series/{{Andromeda}}''.
* Fred from ''Series/{{Angel}}''.
* Chief Tyrol or Specialist Cally on ''Series/{{Battlestar Galactica|Reimagined}}''. Hell, even Starbuck gets into the tech mood now and then (see the Cylon Raider in the first season).
* Warren from ''Series/BuffyTheVampireSlayer'' might be an example of a villainous Mr. Fixit, while Willow was something of a [[WrenchWench Ms. Fixit]].
* Henry on ''{{Eureka}}''.
* The Doctor of ''Series/DoctorWho'' has a tendency to be a MrFixit, though he usually ''has'' seen, encountered, disassembled, built, and even ''created'' some of the items in question.
** Not that that's a requirement. In one episode in new series 3 ("Utopia"), he fixes a rocket mere minutes after admitting he has no idea how it works. What's great is that he applies his own superior-in-normal-circumstances knowledge which gives him a "so obvious they overlooked it" answer (reverse the circuit).
* Kaylee from ''Series/{{Firefly}}'' is another Ms. Fixit, who demonstrated her prowess while having...relations...with her predecessor on ''Serenity''.
** Literally. She was on her back on the engine room floor and she saw what was wrong with the engine while the mechanic was preoccupied with being on top of her. It is implied that she made out with him specifically in order to get a chance to look at the engine of a real spaceship.
* The Professor from ''GilligansIsland'' made a freakin' car out of BambooTechnology, which was actually spoofed in an episode of ''{{Veggietales}}''.
* Heather from ''Series/{{Jericho}}''. The term "Miss Fixit," was actually used as an insult by some members of the fandom who didn't like her. It somewhat backfired when the fans who did like her decided they ''liked'' the nickname.
* Sayid from ''Series/{{Lost}}''.
* Referenced by name in an episode of ''Series/{{Mash}}'' where the nurses wake up Hawkeye (strange in itself given that he's the chief surgeon and dangerously overworked) to fix the heater in their tent. Turns out he's better at fixing people than [[StuffBlowingUp heaters]].
* Sam Carter from ''Series/StargateSG1'' is a Ms. Fixit, as well as a HotScientist and TheSquadette.
* Rodney [=McKay=] from ''Series/StargateAtlantis''.
* Scotty from ''Series/StarTrekTheOriginalSeries''.
* Geordi La Forge from ''Series/StarTrekTheNextGeneration''.
* Miles O'Brien from ''Series/StarTrekDeepSpaceNine''. (being a character transplanted from ''Series/StarTrekTheNextGeneration'', he only displays this same skillset on that show if something goes wrong with a transporter, and then only under Geordi La Forge's supervision).
** Likewise, Rom is dimwitted about everything but technology. He's the only person who understands the mix of Cardassian, Federation, Bajoran and Ferengi parts (as well as several cooking utensils) that make up the electrical components of Quark's bar. His son Nog (also a promising engineer) claims that he could be the Chief Engineer of a starship with the right breaks.
* Harry Kim of ''StarTrekVoyager'' may be an Ensign fresh out of the Academy, but he's almost as much of a mechanical whiz at B'Elanna Torres. He often pitches in with the engineering duties on board the ship and is recognised as an expert on holo-technology. The main difference between Harry and B'Elanna is that while B'Elanna is great at working on her feet with limited resources, Harry is better at theory and design.
* Steve, the director of the "''TopGear'' Technology Centre," who became something of an AscendedExtra after the Britcar 24-Hour Race.
* ''Series/MacGyver''. The guy built a glider out of trash and junk in an attic. Tested on the ''Series/{{Mythbusters}}''.
* Gibbs on ''Series/{{NCIS}}'' with anything mechanical as showcased in ''Power Down''. If it's got electricity running through it, you're pretty much screwed. Let's not even think about computers. But has the power gone out and do you need to make copies with a machine no one has used or heard of in hundred years? Gibbs's got your back.
** That's okay though, if it ''does'' have electricity, odds are both [=McGee=] ''and'' Abbey are capable of fixing it.
* Meg Austin in the first season of ''Series/{{JAG}}'', if it's got anything to do with fixing computers or computerized weapons systems.
* Luis and Maria on ''Series/SesameStreet''.
* Red Green of ''TheRedGreenShow'' is something of a subversion. He fancies himself a practical Mr. Fixit, but his duct-tape reinforced Rube Goldberg inventions only work about half the time.

[[/folder]]

[[folder: Music ]]

* The JasonMraz song "Frank D. Fixer", about his grandfather.

[[/folder]]

[[folder: Tabletop Games ]]

* Nockers from ''TabletopGame/ChangelingTheDreaming''. They've go a knack for all things mechanical, and can fix broken machines by giving them a [[PercussiveMaintenance good hard thump]] or scowling and telling them off.
** Some of the character types from other [[TabletopGame/OldWorldOfDarkness World of Darkness]] settings were also a dab hand at smash repairs, including Sons of Ether from ''TabletopGame/MageTheAscension'' (who think they're doing Science rather than magic) and Glass Walkers from ''TabletopGame/WerewolfTheApocalypse '' (who could talk to the spirits of machines).
** In ''TabletopGame/ChangelingTheLost'', the Wizened often take on this role. They have access to [[FunctionalMagic Contracts]] that allow them to make a hovercraft out of a lawnmower and an inner tube.
* In ''TabletopGame/{{Traveller}}'', Sword Worlders have a great admiration for this. They make machines specifically to make them easy for a DeterminedHomesteader to tinker with.

[[/folder]]

[[folder: Video Games ]]

* Anything at all break down in the ''GearsOfWar'' world for Delta Squad? Damon Baird's on it, with a growl, and a sarcastic comment about how much you guys suck at fixing things. Seriously, this guy basically repairs everything in the game. And then gives you lip about it. If he weren't so funny, (and your allies weren't immune to friendly fire) he'd probably have eaten a shotgun by now.
** Anyone else notice that he looks like a bulked up version of [[VideoGame/FinalFantasyVII Cid Highwind]]?
* Bao-Dur in ''StarWars: KnightsOfTheOldRepublic II''. The player character in both games can become one as well, if his/her "Repair" skill is high enough.
* [[BrutalLegend Eddie Riggs]], as the ultimate roadie can make and fix any stage equipment given the time and resources.
* Slippy Toad in the ''VideoGame/StarFox'' games.
* Lucca in ''VideoGame/ChronoTrigger'', as she single-handedly fixes a robot made with distant future technology the first time she sees it.
* The ''VideoGame/WingCommander'' games have a long series of Mr Fixits, in the form of the various crew chiefs that keep your fighter flying sometimes via the combined magics of DuctTape and strong language. Nicknames for these folks include "Sparks" and "Pliers".
* Jeff from ''VideoGame/EarthBound'', all you needed was a place to sleep for the night and he could turn your Broken Iron into a Slime Generator.
* ''VideoGame/{{Homeworld}}'' is one of the worst offenders regarding this trope. Within minutes of encountering an enemy vessel you've never seen before, you are informed that your own research team is ready to build an identical ship. Even when the ship in question is a millions-year old {{Precursor}} machine that's been lost to time, your trusty Hiigaran scientists can quickly devise countermeasures to them and even reverse-engineer them to produce copies.
* "Mr. Fixit" from ''{{Constructor}}'' is an inversion: he's a cowboy builder who the player can send to sabotage the opposition's houses by "repairing" the [[KillItWithWater plumbing]], [[ShockAndAwe electrics]] or [[MadeOfExplodium gas]].
* In the intro to ''VideoGame/BrainDead13'', Lance Galahad is adamant at fixing computers, and sees that the way to fix one computer is by using [[MacGyvering bubble gum]] for connection... or at least [[SolidGoldPoop a snotty substitute]]. [[YouHaveOutlivedYourUsefulness Unfortunately, all this is slowly and suddenly]] [[TakeOverTheWorld going to hell...]]
* The Engineer in VideoGame/TeamFortress2, although he's better at [[MoreDakka making weapons]] than [[InvertedTrope actually fixing stuff]].
* Kazuichi "Super Higschool Level Mechanic" Souda from ''VisualNovel/SuperDanganRonpa2''.
* ''VideoGame/StrongBadsCoolGameForAttractivePeople'' has the world of video games and ''HomestarRunner'' merging, turning the Poopsmith into "Mista Fixit", who naturally can fix broken objects.
* Patch from VideoGame/TheLegendOfZeldaOracleOfAges. He lives atop Restoration Wall and has the expertise to repair just about anything someone might bring him—provided they participate in his "trap, er… ceremony". Link is required to bring him a broken nut from Symmetry Village to repair it and restore its symmetry. Later, once Link obtains the Broken Sword at the end of a long [[FetchQuest Fetch Quest]], he can bring it to Patch who will transform it into the Noble Sword (or the Master Sword, if the player already has the Noble Sword by means of a Linked Game).

[[folder: Web Animation ]]

* Sarge from ''Machinima/RedVsBlue''. Lopez and Tex have good (if not better) mechanical skills too, but Sarge takes home the trophy for the ''way'' in which he goes about his repairs, such as somehow repairing a jeep without any tools or spare parts. Or better yet, rebuilding Simmons as a cyborg and using the leftover body parts to heal Grif after he was run over by a tank.

[[/folder]]

[[folder: Web Comics ]]

* Tedd in ''Webcomic/ElGoonishShive'' graduated from this into a MadScientist.
* Any of the Sparks from ''Webcomic/GirlGenius''.
** DoubleSubverted all the time, as they often have their projects explode several times in the building progress. Notably, Agatha had a coffee maker she was working on explode, but went on to finish the coffee maker so well that it makes ''[[LemonWackyHello perfect]]'' coffee.

[[folder: Web Original ]]

* At the SuperHeroSchool Whateley Academy in the ''WhateleyUniverse'', there are dozens of such kids. The mutant powers 'gadgeteer' and 'deviser' basically give a person this kind of power. Some are better at building their own devises, and some are better at working on others' gadgets. The side character codenamed Belphegor is excellent at taking other gadgets and devises and adapting them to his needs. However, he tends to steal other people's stuff before doing the adaptation bit.
* [[RedVsBlue Caboose]], despite [[TheDitz being a flagrant dumbass]], has shown considerable skill at maintaining and operating technology. While this was originally limited to getting along well with AI, this has developed into an ability to activate and repair highly rare robotics.

[[folder: Western Animation ]]

* Rhinox from ''WesternAnimation/BeastWars'' manages to create a device for "Extracting Metaphysical Essence from some alien probe." when Rattrap tells him to. Of course he isn't sure it'll work, but it does.
** Wheeljack from ''Franchise/TransformersGeneration1'' is this as well.
* Grampy from the ''BettyBoop'' cartoons.
* Mr. Fixit the Fox from ''TheBusyWorldOfRichardScarry''.
* Subversion: ''WesternAnimation/DarkwingDuck''. Drake Mallard repeatedly ''calls'' himself this in "Dry Hard," but there's little evidence to support it -- until the ending sequence.
* Gyro Gearloose (pictured above) from ''WesternAnimation/DuckTales'' and various Disney comics.
* Tracy, the gorilla from ''WesternAnimation/FilmationsGhostbusters''.
* Gadget in ''WesternAnimation/ChipNDaleRescueRangers''.
* Wildcat from ''WesternAnimation/TaleSpin''.
* Donatello from ''Franchise/TeenageMutantNinjaTurtles''.
* Fixit from ''WesternAnimation/TeenTitans''. Not only can he fix anything, but he chose the name "Fixit" for himself.
* Rocky from ''WesternAnimation/PawPatrol'' assumes this role among the pups due to the extensive collection of usable materials he's collected and the equipment in his pack.
* Skips from ''WesternAnimation/RegularShow''. Except when it comes to computers.
* Otto from ''SuperRobotMonkeyTeamHyperforceGo''.
* Maru from ''WesternAnimation/PlanesFireAndRescue''.

[[folder: Real Life ]]

* NoahAntwiler of ''WebVideo/TheSpoonyExperiment'' fame got an Atari Jaguar to work by constructing a monstrous amalgamation of technology.
* Creator/FredDibnah became this on British TV; he boasted that given enough time and greasy rags he could restore anything that worked with steam propulsion.
