History Main / GadgeteerGenius

* ''WebVideo/CriticalRole''

* ''ComicBook/Shazam!'': The villain King Kull was capable of building all manner of fiendish devices for his schemes, including a spaceship capable of hopping dimensions, a ray that froze the gods in time, and a means of sinking entire continents. Not bad for a caveman.

%%* [[SpellMyNameWithAnS Kana/Kanna]] from ''Manga/{{NEEDLESS}}'' has this as her superpower. (Administrivia/ZeroContextExample)

** The Doctor can save the universe [[Recap/DoctorWho2007CiNSTimeCrash with a kettle and some string]], though they usually do so off-camera. They also have a knack for taking diabolical inventions cobbled up for some nefarious purpose and subverting their intended purpose, usually with disastrous results for the villain of the day. To name some more specific examples:

%% This page has been alphabetized. Please add new examples in the correct order. Thanks!

** The Doctor can save the universe with a kettle and some string, though they usually do so off-camera. They also have a knack for taking diabolical inventions cobbled up for some nefarious purpose and subverting their intended purpose, usually with disastrous results for the villain of the day. To name some more specific examples:

* ''WebVideo/SMPLive'':
** Cooper enjoys creating complicated farms and redstone traps.
** Dinkster is highly skilled with redstone and creates a lot of contraptions around the server.

* ''WebOriginal/AcademyOfSuperheroes'': Gimble makes physics-violating tech that ''everyone'' can use -- even [[AntiMagic Anchors]].

* ''WebVideo/CriticalRole'' has Percy de Rolo, an exiled nobleman who, with a bit [[DemonicPossession supernatural help]], invents of the first gun -- along with [[{{Deconstruction}} everything]] [[NiceJobBreakingItHero that entails]]. As Vox Machina's resident tinkerer and inventor, he creates a grappling-hook arrow, a saddlebag bomb, an electrified gauntlet, several explosive arrows, a grenade, a prosthetic hand, and perhaps most impressive, [[spoiler:a spring trap that's able to hold an ancient black dragon to the ground for several rounds of combat]]. His inventions are also notable in that Taliesin, Percy's player, must prove that each of them can be created with the materials and technology he would have at his disposal before he gets the go-ahead from the DM.

** The Astro-Naut was [[TheSparkOfGenius so smart]] that he could recreate alien technologies after just seeing it being used.

* In the ''Literature/TheCampHalfBloodSeries'', all of Hephaestus's demigod children are this. Their cabin is ''much'' BiggerOnTheInside due to very clever (and probably impossible) design. Leo Valdez from ''Literature/TheHeroesOfOlympus'' is probably the most notable example in the series. Even when he's doing nothing in particular, he still can fashion incredible machines. When he puts his mind to something, he can make automatons or huge warships. Other notable examples include InspirationalMartyr Charles Beckendorf from ''Literature/{{Percy Jackson|AndTheOlympians}}'' and little 8 year old Harley from ''Literature/TheTrialsOfApollo''.

* The District 3 boy in the ''Literature/TheHungerGames'' and Beetee (also from District 3) in ''Literature/CatchingFire''. District 3 makes electronics and explosives, so, yeah...

* ''ComicBook/AstroCity'':
** Beautie's origin: [[spoiler:She was built by a girl Gadgeteer Genius, the still more brilliant daughter of another Gadgeteer Genius. Her father's reaction leads to Bad Things for both Beautie and the daughter.]]
** The Junkman, who uses stuff that's been thrown out to create his devices (as he considers himself cast off by society because of his age). Despite the self-imposed handicap, he is one of the few villains in Astro City who [[spoiler:actually win]], as it is implied that he [[spoiler:gets away from his trial]] with the recognition he craved and all the loot he stole.
** Jack-In-The-Box, who is the CEO and lead inventor at a toy company, and whose weapons are enhanced versions of his various products. He's also smart enough to cobble together a quick-freeze spray from leftover car parts in a junkyard.

** The briefly seen Vivian Vector, who seems to be a RobotMaster of the Doctor Doom variety (applied ranting and all). However, most of her inventions were actually stolen via MindRape on her college roommate.

* Tim Drake ([[ComicBook/RobinSeries Robin III]]/[[ComicBook/RedRobin Red Robin III]]) was the first member of the Batfamily to figure out how to get fully functional access to the Batcomputer while on the go in his suit, designed and built several of his own weapons and vehicles, figured out new gadgets to weaponize his suit, figured out how to alter his cape for gliding, and was a huge fanboy of both Batman and Blue Beetle long before donning a mask himself.

* [[WesternAnimation/KungFuPanda2 Lord Shen]] is shown to be this in ''Fanfic/TheVow''. He has designed himself his modified [[BladeOnAStick Guan Dao]] and the Iron Claws protecting his feet. He also invents firework shooters to ensure safe launches. He later uses those designs to create his cannons. He's also the one who's hired to invent the restraint that keeps [[OneManArmy Tai Lung]] mobilized for twenty years.

* The ''Literature/{{Lensmen}}'' series is full of people that might qualify, but [=LaVerne=] "Thorny" Thorndyke in particular is known in-universe for being this -- and that really says something, when the universe in question is the trope namer for the LensmanArmsRace. He was the project leader for building at least three of the planet-destroying weapons in the series, among other things.

[[folder:Video Games]]
%%* Lash from ''VideoGame/AdvanceWars'', who combines this trope with being an EnfanteTerrible, much to the protagonists' dismay. (Administrivia/ZeroContextExample)
* Amanda Ripley of ''VideoGame/AlienIsolation'' at one point manages to repair a motion tracker unit using parts from a children's toy. She also crafts her own medkits, explosives, and electronic decoys from random gubbins and scrap metal parts she finds lying around the station.
* ''VideoGame/ArcanumOfSteamworksAndMagickObscura'' allows players to be Gadgeteer Geniuses, eventually building such things as steam-powered robots, staffs that shoot lightning, and a device that can revive the dead.
* Jan Jansen from ''VideoGame/BaldursGateII'' starts the game with a crossbow (including bolts), gloves, boots, and goggles of his own design, most of which give him a big bonus to his thieving skills. Originally, he would have invented more gadgets as the game went on, but this was sadly [[DummiedOut scrapped due to lack of development time]].
* Phoebe from ''VideoGame/{{Battleborn}}'' is a genius inventor who has created a variety of fantastical tech, a number of which have been inspired by Eldrid tech that seem almost [[MagicFromTechnology magical in nature]]. Among her inventions include phasegate tech, which allows her to teleport around the battlefield; her high tech and fashionable BattleBallgown, which aids her when fighting; and a cybernetic implant which allows her to telekinetically control four of her five rapiers. She's also a skilled roboticist, having been the brains behind her fellow Battleborn Kid Ultra's original design and purpose.
* One of ''VideoGame/BattleCryVideoGame'''s classes -- called Gadgeteer, naturally enough -- has this as their job.
%%** Jin, on the Han Republic team, is a particular example. (Administrivia/ZeroContextExample)
* ''VideoGame/Borderlands2'':
** [[DownloadableContent The Mechromancer]], Gaige, created a giant killer robot when she was still in high school, a design that was stolen by her rival and sold to the police force on her home planet. [[SuccessThroughInsanity She also made herself a robotic arm, after sawing off her old one.]]
** It's easily overlooked given who he is, but Scooter qualifies. To quote Angel: "He may be missing a few chromosomes, but he's a savant when it comes to vehicles."
%%** Ellie, Scooter's sister, qualifies as well. (Administrivia/ZeroContextExample)
%%* Momo from ''VideoGame/BreathOfFireIII''. (Administrivia/ZeroContextExample)
* Gadgeteering exists as a power set in ''VideoGame/ChampionsOnline''. One of the abilities is an "Experimental Ray" which has a chance for various effects, including turning the target into a teddy bear.
* Lucca in ''VideoGame/ChronoTrigger''. She resides in a more-or-less modern kingdom with swords and medieval aesthetics, yet she is able to build a fully functioning ''teleporter'', and when the party comes across a robot from the year 2300 she has little trouble fixing him up.
* Gary the Gadget Guy from ''VideoGame/ClubPenguin'', in case the name doesn't make it obvious. He's responsible for most, if not all of the technology on the island, as well as all the PSA and EPF technology.
* Billy Blaze, alias Commander Keen, from id Software's ''VideoGame/CommanderKeen'' series. Commander Keen built a spaceship in his garden, made from old soup cans, a joystick, a car battery, a vacuum cleaner, and a bottle of Everclear.
* Max from ''VideoGame/DarkChronicle'' can make items out of pretty much anything he sees. He just needs to [[FirstPersonSnapshooter capture photos]] for inspiration.
* The Combo Weapon mechanic in ''VideoGame/DeadRising2'' and ''[[VideoGame/DeadRising3 3]]'' turns the protagonists into this, being able to [[MacGyvering MacGyver]] weapons out of whatever random crap they can find, including boxing glove claws, water gun flamethrowers, crossbows armed with exploding firework rockets, and even a fully functional ''lightsaber''. Nick from ''3'' takes this even further by being able to build Combo Weapons on the spot without needing a workbench, and even build combo ''vehicles''.
* ''VideoGame/DevilMayCry5'' introduces Nico, a former gunsmith and the mechanic partner (and driver) of Nero responsible for the [[ArtificialLimbs Devil Breaker]] system. Some of these arms are simple, like the [[ShockAndAwe Overture, which simply lets out electric blasts]], and the Rawhide, which is a chain whip that can improve his Wire Snatch, but some can give Nero a RocketPunch that he can '''ride on''' or abilities like turning his pistol into a ''railgun'' or ''even '''slowing down time itself.''''' Not that surprising for her as she uses pieces of defeated demons to make these for Nero. She also gives Dante [[spoiler:Dr. Faust, a literal magic '''hat''' that she made based on her father's research that uses red orbs as ammunition]].
* In ''VideoGame/DiceyDungeons'', the Inventor can turn her equipment into gadgets which can be used for free each turn. The downside? She ''has'' to make a new gadget after each fight, which means you're constantly throwing away your items.
* Jennifer from ''VideoGame/DisgaeaHourOfDarkness'' created super-robot Thursday at the age of 5.
* ''Franchise/DonkeyKong'': Funky Kong can make helicopters, watercraft, and guns out of BambooTechnology. All while being a SurferDude. In ''VideoGame/DonkeyKongCountry3DixieKongsDoubleTrouble'', he'll use discarded items the Kongs pick up to create vehicles for them to travel around in, from a simple motorboat to a helicopter.
* Jeff Andonuts of ''VideoGame/EarthBound1994''. He's capable of using laser guns, bombs, and the like, and can turn various broken irons, antennas, harmonicas, and the like into powerful weapons and battle items overnight. And did we mention that he's only thirteen years old?
* ''VideoGame/EagleEyeMysteries'': WordOfGod says that Jennifer Eagle's character was created specifically for her to be this. In-game, she built the Eagle Eye Detective Agency's TRAVIS hand-held computer, and is rather picky about who gets to wield it (only Eagle Eye members have the privilege).
* ''VideoGame/{{Fallout}}'':
** In ''VideoGame/FalloutNewVegas'', [[PlayerCharacter The Courier]] can become one with the "Jury Rigging" perk. Repairing a chainsaw with a baseball bat? A PowerArmor helmet with a baseball cap? An antimateriel rifle with a BB gun? You can do it. As the perk's description says: "[[LampshadeHanging How does it work?]] [[ImpossibleGenius Nobody knows... except you.]]"
** The [[PlayerCharacter Sole Survivor]] in ''VideoGame/Fallout4'' can strip everyday household items like alarm clocks, silverware, or board games for raw materials, which can then be used to make turrets, generators, computers, and modifications for weapons, armor, and even power armor. With the ''Automatron'' DLC, they can even use raw materials to build their own army of MechaMooks.
* ''Franchise/FinalFantasy'':
** If a character in any ''Final Fantasy'' game is called Cid, two things are almost certain: 1) He's a Gadgeteer Genius and 2) his specialty will be [[CoolAirship Airships]]. For example:
*** Never seen, but Cid of the Lufaine in ''VideoGame/FinalFantasyI'' (at least all its remakes) was the inventor of the first airship.
*** The very first Cid appears in ''VideoGame/FinalFantasyII'', who offers taxi service with his airship to the heroes.
*** ''VideoGame/FinalFantasyIII'' gives us Cid Haze, skilled enough to convert a CoolShip into a CoolAirship.
*** Cid Pollendina of ''VideoGame/FinalFantasyIV'' is the first playable Cid, who refuses to let little things like [[RidingTheBomb riding a nuke into an enemy vessel]] and an avalanche of millions of tons of rock and magma stop him from fixing up your airship. He's also a CoolOldGuy[=/=]BoisterousBruiser, which would become recurring Cid traits.
*** ''VideoGame/FinalFantasyV'''s Cid Previa builds airships, surprise surprise, and makes Crystal Power Enhancing... [[BuffySpeak Thingies]]. His grandson, Mid, might represent this trope even more.
*** Cid Del Norte Marquez from ''VideoGame/FinalFantasyVI'' oddly enough doesn't work with Airships, but is no less of a Gadgeteer Genius, seeing as he invented {{Magitek}} and designs PoweredArmor, weapons, and even pseudo-genetic engineering. However, if you go out of your way to visit the crashed Blackjack after Terra and Locke leave Vector on the way to the Crescent Island, you can find Cid on board offering to help Setzer repair it, claiming that he has some prior experience with airships. Setzer politely turns him down.
*** Cid Highwind of ''VideoGame/FinalFantasyVII'' fame is probably the most well known on this list. He does the same in the ''Franchise/KingdomHearts'' games, except he doesn't fight. [[NoSmoking Or smoke]] (he gets a toothpick). [[{{Bowdlerise}} Or swear.]]
*** Cid Kramer of ''VideoGame/FinalFantasyVIII'' put up part of the money used to rebuild the mass people mover that would eventually become Balamb Garden [[spoiler: (the rest comes from TheMafia, which causes problems later on)]], which functions as the party's primary mode of transportation early in the story, and negotiates with a city of engineers to help actually create it to his specifications.
*** Cid Fabool IX of ''VideoGame/FinalFantasyIX''. His proficiency at designing airships has led Lindblum to become Gaia's prominent air power. [[ForcedTransformation He also spends some time as a frog after an argument with his wife.]]
*** ''VideoGame/FinalFantasyX'''s Cid. He builds airships and he's loud and boisterous. He doesn't really bring anything new to the table.
*** ''VideoGame/FinalFantasyXI'''s Cid is, fittingly enough, the most prominent engineer and inventor in Vana'diel.
*** ''VideoGame/FinalFantasyXII'''s Cidolfus Demen Bunansa (Dr. Cid for short) is the first Cid to actually feature as a fully fledged villain, being the MadScientist responsible for most of the airships and weapons built for the [[TheEmpire Archadian Empire]].
*** ''VideoGame/FinalFantasyXIV'''s Cid Nan Garlond is a defector from the evil [[TheEmpire Garlean Empire]], who are incapable of using magic. His family was credited with making some of the first airships, and after coming to Eorzia, Cid brings a wealth of Garlean technology and creates a technological boom in the fairly medieval-flavored game world, creating a steampunk industrial revolution.
*** ''VideoGame/FinalFantasyXV'''s Cindy (Grandpa Cid retired). She's an attractive WrenchWench who works on the gang's car... which can equip a jet transformation mod.
** Edgar from ''VideoGame/FinalFantasyVI'' designed many of the machines used and exported by his kingdom, including the weapons he uses in battle, most infamously his [[ChainsawGood giant chainsaw]]. His Job class is described as "Machinist" and, where everyone else is wielding swords, knives, or staffs, Edgar is the only one holding [[HandCannon a huge gun]].
** From ''VideoGame/FinalFantasyX'', Cid's daughter [[GenkiGirl Rikku]] counts as well, with her "Mix" [[LimitBreak Overdrive]]. Both of them are Al Bhed, which are exceptionally technologically advanced, the rest of the game world having been Luddites until shortly before the beginning of ''VideoGame/FinalFantasyX2''.
** Shinra from ''VideoGame/FinalFantasyX2'', who is another Al Bhed.
** The Machinist job in ''VideoGame/FinalFantasyXIV'' uses a [[TheGunslinger firearm]] in conjunction with a waist-mounted [[{{Magitek}} aetherotransformer]] which holds special ammunition, a wrench for Dismantle and Reassemble skills, a stash of grenades, and their foldable {{Attack Drone}}s.
** Nono the airship mechanic from ''VideoGame/FinalFantasyTacticsAdvance'' and ''VideoGame/FinalFantasyXII''. In ''VideoGame/FinalFantasyTacticsA2'', Hurdy explains that Nono built his own airship called "Brilliante I".
* In ''VideoGame/GemsOfWar'', Sparkgrinder is a gifted inventor, but not very good at [[KillerRobot controlling his inventions]].
* The whole of the Engineer class from ''Franchise/GuildWars'' focuses on the use of inventive gadgets to fit multiple situations -- you quickly forget that you're limited to pistols, rifles, and shields as conventional weapons when you start using flamethrowers, turrets, grenades bombs, and wrenches as class-specific weapon kits.
%%** Many of the Asura race qualify, but especially [[http://wiki.guildwars2.com/wiki/Zojja Zojja]] from ''VideoGame/GuildWars2''. (Administrivia/ZeroContextExample)
* The Vances from ''VideoGame/HalfLife2''. Eli built a [[RobotBuddy robotic dog]] for his daughter, Alyx. Over the years, she upgraded Dog into a super-strong, semi-sentient LightningBruiser.
%%* Andy from ''VideoGame/HeartOfDarkness'' is pretty much a clone of Billy Blaze above. (Administrivia/ZeroContextExample)
* Monty from ''VideoGame/{{Kindergarten}}'' is, in his own words, pretty handy with gadgets. He's able to modify a voice-controlled bomb into being remote controlled instead, and the wheelchair he's been confined to in ''VideoGame/Kindergarten2'' has a laser cannon that he knows how to modify and most likely put in himself to begin with.
* Victoria Van Bathysphere from ''VideoGame/LittleBigPlanet 2''. The later portion of her level is an EternalEngine and she made a robot army.
* Bernard from the ''VideoGame/ManiacMansion'' fangame ''VideoGame/ManiacMansionMania''. He even invented a wheel that never stops rolling. And it can be used as a power source!
* Carl, your chief engineer in ''VideoGame/MechWarrior 4'', has a reputation as one. The saying goes, "Give Carl a hundred tons of steel wool and he'll knit you an Atlas overnight."
* ''Franchise/MegaMan'':
** ''VideoGame/MegaManLegends'': Found some old broken drill or toy laser sword? Take it to Roll and she'll figure out how to make a new weapon out of it!
%%*** Tron Bonne. (Administrivia/ZeroContextExample)
** Ciel from ''VideoGame/MegaManZero''. And Roll seems like an amateur compared to her. Her accomplishments? Creating a perfect replica of X (Cain certainly couldn't, partially why mavericks exist), creating an energy system to solve the energy crisis that is not only effective but just beautiful (take a look at the reactor of the Guardian airship from ''[[VideoGame/MegaManZX ZX]]''!), and making Biometals to match Master Albert's, but also adding the dual Mega-Merge feature. And she created Copy-X when she was ''nine years old''.
%%* Ethan from ''VideoGame/MonsterTale''. For bonus points, his theme tune is titled "gadgeteer". (Administrivia/ZeroContextExample; elaborate on how he's this ''in-game'', not just in the soundtrack)
* [[spoiler:Deus Diablo]] in ''VideoGame/TheNamelessMod''. He built an inanimate object with the powers of a board admin, something [[spoiler:Gamespy]] couldn't do, hence why he was [[spoiler:kidnapped]].
* [[RealityWarper Conduits]] in ''[[VideoGame/NexusWar Nexus Clash]]'' are ''supernaturally'' good at crafting, tinkering, and alchemy, to the point that (with the favor of the RandomNumberGod) it's entirely possible for a Conduit to craft something and find all of their materials still intact and unused on the workbench afterwards. People who think too hard about how impossible that is tend not to become Conduits.
* Junkrat from ''VideoGame/{{Overwatch}}''. He may be a twitchy criminal with a penchant for explosions, but the guy managed to craft up some impressive weaponry. His grenade launcher, remote concussive mine, and springtrap are all his creations, along with his incredibly powerful Riptire. There's even a good chance that his artificial hand and leg are hand crafted.
* ''VideoGame/{{Paladins}}'':
** Barik is a dwarf who is known by the title of Master Mechanic. He was one of the key engineers of the [[{{Magitek}} crystal-powered technology]] spreading through the Realm. Since then, his signature contributions have appeared in almost every field and vocation, from mechanized mining suits and rocket-powered wings to the crystalline weapons used by Magistrate and Resistance soldiers alike.
** Ruckus is a tiny goblin who fights in a MiniMecha that he repurposed from a mining mech. To increase his mech's power, he installed a crystal that was actually the mind-stone of a war golem. This mind-stone now uses the mech suit as his new body and is now partners with Ruckus under his new name, Bolt.
* ''Franchise/{{Pokemon}}'':
** This trait seems to be the hat of most [[ShockAndAwe electric type]] specialists. With the exception of [[VideoGame/PokemonBlackAndWhite Elesa]] due to being a model, [[VideoGame/PokemonRedAndBlue Lt. Surge]], [[VideoGame/PokemonRubyAndSapphire Watson]], [[VideoGame/PokemonDiamondAndPearl Volkner]], and [[VideoGame/PokemonXAndY Clemont]] had a huge hand in setting up the complex design mechanisms for their gyms for one reason or another, and [[VideoGame/PokemonSunAndMoon Sophocles]] constructs a device that's integral to his Island Trial.
** Bill from ''VideoGame/PokemonRedAndBlue'', who invented the storage system (as well as his colleagues who helped him) in addition to a [[TeleporterAccident teleporter]] and TimeMachine. In ''Manga/PokemonAdventures'', he also invented the Vs. Seeker.
* Many operators in ''VideoGame/RainbowSixSiege'' have engineering degrees and develop their own specialized equipment. Examples include explosive traps, signal jammers, sensors that detect people or electronics through walls, a drone with a mounted taser, and a breaching device that can punch a hole in a wall and launch several grenades through it.
* The Lombaxes from ''Franchise/RatchetAndClank'' are [[PlanetOfHats an entire race]] of Gadgeteer Geniuses. Ratchet himself was able to build a functioning space ship out of [[strike:[[MemeticMutation A BOX OF SCRAPS!]]]] spare parts [[strike:[[Film/IronMan1 IN A CAVE!]]]] on Veldin simply by following Gadgetron's voice prompts (not to mention the list of his wacky inventions that Clank rattled off), and the Lombax Secret is in fact [[spoiler:an inter-dimensional portal device]]. According to the Smuggler, Lombaxes can't leave ''any'' invention the way they found it and are forever tinkering.
* Lucas Baker from ''VideoGame/ResidentEvil7'' is a truly evil example. He's able to make all different kinds of devices of torture for the sick games he plays with his victims, and he does it all under his family's nose.
* Li Kohran from ''VideoGame/SakuraWars'', though the stuff she makes also has a tendency to randomly explode.
* Episode 2 of ''VideoGame/ScoobyDooFirstFrights'' has Mystery, Inc. encounter Numbers, a boy who invents gadgets to try and track down the culprit behind the toy army at the carnival.
* ''VideoGame/ScrapMechanic'' has every PlayerCharacter as a Gadgeteer Genius, capable of building marvellous machines out of nothing more than repurposed agricultural and logistical equipment. [[SurvivalSandbox And they're going to need it, too.]]
* Grubb from ''VideoGame/SepterraCore''. He built several robots of different types out of rubbish thrown down from Terra 1.
* ''VideoGame/SlyCooper'':
** Bentley is a techno genius who even fitted his wheelchair with gadgets.
** His [[spoiler:ex-]]girlfriend Penelope is one as well, [[spoiler:albeit a villainous example]]. She's more specifically focused on RC technology, having made for example a remote-controlled car with a turret mounted to it.
* ''VideoGame/{{Solatorobo}}'' has Merveille, who is credited with single-handedly raising the bar for Kurvasz MiniMecha design. [[spoiler:She's also quite skilled in biology, CreatingLife while barely old enough to be out of high school.]]
%%** The shopkeeper Suzette and Red's sister Chocolat are both {{Wrench Wench}}es. (Administrivia/ZeroContextExample)
* ''VideoGame/SonicTheHedgehog'':
** In most ''Sonic'' media, Miles "Tails" Prower is the "gadget" guy.
** Dr. Eggman is capable of building entire robot armies and armadas of airships in what can't be more than a few weeks or months. His creations also appear to have well-nigh-unlimited power, fuel, and ammunition, as well as effectively healing technology on several examples.
* Marina from ''VideoGame/Splatoon2'' is quite an enthusiast regarding machines, as her stage intro dialogue shows. She even creates a new Shifty Station stage for each Splatfest, using advanced Octarian technology. [[spoiler:The ''Octo Expansion'' reveals that she was actually a top combat engineer for the Octarians before her HeelFaceTurn, having graduated from her elementary training at the age of ''nine''.]]
* Area from ''[[VideoGame/StreetFighterEX Street Fighter EX2 Plus]]''. While she's not given much of a story, it's mentioned that she's a greater inventor than her father.
* ''VideoGame/TheStretchers'':
** Professor Doctor is not only the brains behind the De-Dizzler 3000, which cures the Dizzies of their condition, but also your source for ambulance upgrades.
** Captain Brains is a villainous example, having the technology behind the Dizzying pandemic in the first place.
* ''VideoGame/{{Subverse}}'' has two alien examples: Dallick, a diminutive stoner who nonetheless is a genius mechanic, especially for ships and advanced electronics, and Taron, a CatGirl "nikith" who aside from being an extremely skilled and acrobatic huntress also has an incredible love and talent for technology, able to invent a set of highly-advanced, custom-made burglar's tools that let her bypass any sort of known security system in the Prodigium galaxy.
* ''Franchise/SuperMarioBros'':
** Just about any unusual tech in the Mushroom Kingdom comes from Professor E. Gadd's lab.
** Luigi becomes this as Mr. L in ''VideoGame/SuperPaperMario''. He's an expert in [[{{Pun}} brobotics]], to be sure.
** The sixth boss of ''VideoGame/PaperMario64'', [[{{Cumulonemesis}} Huff N. Puff]], built the Puff-Puff Machine, which was used to block out the sun in Flower Fields, as well as block the entrance to his [[LevelInTheClouds cloudy lair]].
** The ''VideoGame/{{Wario}}'' franchise:
*** Wario himself is surprisingly this, considering that in ''VideoGame/WarioMasterOfDisguise'', he's able to create a device that allows him to go in and out of his television at will. He is also shown to create other devices in the ''VideoGame/WarioWare'' series as well.
*** Captain Syrup in ''VideoGame/WarioLandII''. All the boss fights against her involve knocking her out of various hovering vehicles that sport various weapons, and one fight sees her remotely controlling a robotic Spear Man.
*** Little MadScientist girl Penny Crygor from ''VideoGame/WarioWare: Smooth Moves'' fits the trope to the letter. She's also [[TheCutie totally adorable]]. Her story in ''Smooth Moves'' has her participate in an "Invent-Off" against her granddad Dr. Crygor, who is a Mad Scientist himself, and she wins. In ''Get It Together'', she uses a water jetpack she made herself to move around.
%%** Shy Guys, who count as Gadgeteer Genius {{Mooks}}. (Administrivia/ZeroContextExample)
* The Engineer of ''VideoGame/TeamFortress2'' is capable of creating NASA-level sentry turrets and teleportation devices using nothing more than his wrench and scrap metal collected from weapons dropped by the recently dead. There's also his laws-of-thermodynamics-be-damned dispenser, and the fact that he can make one from scratch using things such as a wooden baseball bat, an empty glass bottle, or a glass jar filled with urine. He's also the person who invented it. In the 60s. Then again, he does have [[OmnidisciplinaryScientist 11 PhDs]], so it's a little justified. He also built himself a robotic hand to replace his missing right hand. [[MadScientist A hand that he cut off so he could replace it with a robotic hand.]]
* ''Franchise/TouhouProject'':
** Nitori and the Kappa race in general. In a setting that has a medieval level of technology, [[SchizoTech Nitori has managed to create things like]] [[InvisibilityCloak optical camo suits]].
** Rika managed to build, arm, and pilot at least ''three'' separate [[TankGoodness tanks]] designs in a setting devoid of the industrial-grade machinery usually required to construct one.
* The Gadgeteer is the name of a class in ''VideoGame/TwilightHeroes'' -- they make many of the gadgets and devices that they use in combat.
%%* ''VideoGame/UnwrittenLegends'' has two classes based on gadgeteering, making the characters either this or at least the GeniusDitz. (Administrivia/ZeroContextExample; what are these classes, and how are they distinct?)
* Puck of ''VideoGame/VanguardBandits'' is capable of repairing the strongest and oldest [[AMechByAnyOtherName ATACs]] in record time and can keep them in working order with the smallest of resources. [[spoiler:Taken to extreme levels, as he proves that he is fully capable of making an [=ATAC=] even stronger than the one legends portrayed as strongest using only scrap parts of a broken machine and a weaker power source.]] Takes a dark twist at the end of the "Ruin" path, when he improves [[spoiler:Zulwarn]]'s efficiency. [[spoiler:It only needs a few ''drops'' of blood instead of a mass human sacrifice to power it, though it still corrupts people.]]
* The Gadgeteer is an actual class in ''VideoGame/{{Wizardry}} 8'', and it's just as powerful as you'd expect. Thankfully the rarity of components means that you can't really have more than one in the party, which keeps the game from becoming unbalanced. The only gadgeteer in-game if you don't make one in your party is a trynnie named Madras, who calls himself a gadgeteer by name.
* ''VideoGame/WorldOfWarcraft'':
** This trope is the defining characteristic of both Gnomes (Alliance) and Goblins (Horde). Gnomish tinkerers are famous for inventing bizarre (if not reality-warping) inventions including (but not limited to) helicopters, robot chickens, teleporters, mind control helmets, and even world shrinkers. Goblins on the other hand tend to love explosives of all kinds and are master bombmakers, rocketeers, and sappers; but also make lumber-harvesting robots, airships, and motorcycles. Although generally on opposite factions, Gnomes and Goblins have a friendly rivalry and often cooperate on complex engineering tasks and love to compete in racing.
** Players of any race can take the "Engineering" profession, which allows them to embody this trope, but Gnomes have a racial bonus to Engineering (Goblins have a racial bonus to Alchemy). The profession even allows the player to create MadScientist-style goggles and to make unique modifications to their armor, such as parachute cloaks and rocket boots. Although true to Gnomish and Goblin tradition, player-made inventions have a nasty tendency to backfire through explosions, accidental size modification, poultryfication, and teleporting you far above the ground. If it does not do any of this it is either a bomb, has a massive cooldown time, or is a robot or something that works once before breaking.

[[folder:Western Animation]]
* Jimmy Neutron from ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'' is only a kid, but he has already surpassed any known scientist in capability. Each episode focuses on one of his inventions, although they usually fall prey to FlowersForAlgernonSyndrome.
* Alan of ''WesternAnimation/TheAmazingChanAndTheChanClan'' programmed the iconic Chan Van to be able to transform into just about anything. Even a dynamite truck.
* Buckle from ''WesternAnimation/AmericanDad'', a former [[Ride/DisneyThemeParks Disney Imagineer]] who became a mountain man. Just look at his haunted house:
-->'''Francine:''' ''[disturbed]'' I actually don't know how I got out. The front hallway spiraled into a black hole and the weather kept changing and ''I was a child again''.
* ''WesternAnimation/{{Arcane}}'':
** Despite all her bombs being duds [[spoiler:until Episode 3]], Jinx is still gifted enough with machinery that she built a working panic button in Vander's bar, which he uses to successfully alert Vi's crew to the incoming Enforcers out to arrest them. Her naming her weaponry like she did with her bombs in childhood implies that they were also made by herself. Silco even outright states that she's his best option for actually weaponizing the Piltie tech she stole, seeming to show that she's become this for his whole gang. She's shown to be able to reproduce Jayce's first Hextech experiment with reasonable accuracy (if not similar quality) and demonstrates an understanding of the underlying principles from reading his notes, which she managed to learn within the span of hours. This shows that her childish behavior belies her intelligence.
** Ekko works as a mechanic in Benzo's pawn shop and tinkers with what's inside, and has built an impressive system to spy on the inside of the store. [[spoiler:He's the one who designed the hoverboards the Firelights use and can talk shop with Heimerdinger about one's parts.]]
%%** Jayce. (Administrivia/ZeroContextExample)
%%** Viktor.
* The ''Franchise/AvatarTheLastAirbender'' franchise:
** ''WesternAnimation/AvatarTheLastAirbender'':
*** The Mechanist is capable of creating a number of SchizoTech contraptions like tanks, hot air balloons, and even submarines.
*** Sokka, who is the Mechanist's protege, came up with the idea for the submarine in the first place.
** ''WesternAnimation/TheLegendOfKorra'':
*** Varrick may be an EccentricMillionaire, but he's also a very capable scientist and engineer, and quite capable of building what he needs on the fly.
*** Asami Sato didn't just inherit her father's industrial company, she also inherited his engineering genius. She can build a sand glider out of ship scraps, come up with innovative infrastructure ideas to incorporate spirit wilds into the city, and design biomimetic flying mech suits, among other things.
* ComicBook/TheFalcon is characterized in this manner in ''WesternAnimation/AvengersAssemble'', even though [[AdaptationalIntelligence that's not how he's traditionally depicted in the comics]]. Compared to [[ComicBook/IronMan Stark]], Falcon's inventions tend to be smaller, but fulfill more specific functions. He basically becomes the team's Franchise/{{Batman}}.
* Arthur in ''WesternAnimation/{{Babar}}'' designs a bicycle-impulsed flying machine, two robots, and a submarine, among other things.
* Rattrap in ''WesternAnimation/BeastMachines'' was stripped of all weapons upon being reformatted, so compensated by developing all sorts of handy devices to stop the Vehicons.
* The later ''WesternAnimation/BettyBoop'' cartoons often feature Grampy, who creates all kinds of creative gadgets and machines from discarded junk.
* Mouse from ''WesternAnimation/BoyGirlDogCatMouseCheese'' builds robots and gadgets which serve various functions.
* [[TheCynic Grumpy]] from ''WesternAnimation/CareBearsAdventuresInCareALot'' straddles the line between this and BunglingInventor. He apparently built an entire theme park at one point, not to mention a cloning device, among many others, but his inventions sometimes turn on him (i.e. the clone clones itself and both clones kick him out for not being "Grumpy" enough) or fail because of ([[UnwantedAssistance unwanted]]) help from Oopsy.
* In addition to commentary, Wrestling/StoneColdSteveAustin provides this service in the original run of ''WesternAnimation/CelebrityDeathmatch''. His technological expertise yielded a fully-functional cloning machine (used to combine DNA from dead celebrites into fighting mutants) and a rickety time machine (used to bring to life such matches as The Three Tenors vs. The Three Stooges).
* [[MeaningfulName Gadget Hackwrench]] from ''WesternAnimation/ChipNDaleRescueRangers'', who builds the team's vehicles and equipment. The stuff she makes is particularly impressive because all she usually has to work with is [[MacGyvering discarded junk]] from the humans. When Gadget returns as BigGood of the titular HeroesRUs team in ''Literature/TheMouseWatch'', she's no longer restricted to BambooTechnology. She now invents sci-fi tech such as "[[GogglesDoSomethingUnusual Smart Goggles]]" that act as {{Everything Sensor}}s and create holographic disguises, a CoolBike that is assembled by {{Nanomachines}} at the push of a button, and a [[CoolTrain worldwide subway system]] that can go from UsefulNotes/LosAngeles to UsefulNotes/NewYorkCity in ''ten minutes''.
* Philly Phil from ''WesternAnimation/ClassOf3000'' is the class's go-to guy when they need some kind of gadget. They do have a tendency to malfunction, though.
* Jérémie from ''WesternAnimation/CodeLyoko''. His gadgeteering occurs more in the virtual world, however, as he is the primary programmer and the one who is most adept at using the Supercomputer. However, it is a confirmed fact that he can build robots, participating in a robot competition in Season 1. He also creates an EMP bomb in the episode "[[Recap/CodeLyokoS2E15 Ultimatum]]", which efficiently stuns a [=XANAfied=] person.
* ''WesternAnimation/CodenameKidsNextDoor'':
** They make holographic projectors out of steam engines and lasers out of a flashlight, a piece of wood, and a bottle!
** If you're looking for a person example, Numbuh 2 would be the man. Once you get past his [[{{Pun}} punny]] way of life, he is one of the KND's best of these, if not arguably the best. In fact, he's considered so good that when plenty of other scientist kids are kidnapped by the supposed "Splinter Cell", special interest is put into protecting him by putting him into hiding. As Numbuh One puts it, if they get their hands on Numbuh 2, they'll be able to build almost anything.
* Jack and Maddie Fenton in ''WesternAnimation/DannyPhantom'' seem to fit this trope, with their inventions being proven inoperable by a normal person, or even [[TheMenInBlack The Guys In White]], due to their quirks because of their "tin cans and an old transistor radio" method of construction.
* ''WesternAnimation/DextersLaboratory'' has a gadgeteer for its titular main character, who creates a lot of science inventions throughout the series.
%%* ''Franchise/DisneyFairies'': Tinkerbell is one of these in her origin story movie. This actually comes from the original J. M. Barrie's ''Literature/PeterPan'', in which she mends pots and kettles, at least. The name really does come from her being a tinkerer. (Administrivia/ZeroContextExample; how does it apply to the ''movie''?)
* Edd from ''WesternAnimation/EdEddNEddy''. He makes an industrial-grade excavator out of junk he found around his neighborhood.
* AJ from ''WesternAnimation/TheFairlyOddparents'' has a secret lab in his bedroom which he uses to create clones, inventions, and conduct scientific research.
* The title character of ''WesternAnimation/FlavioTheGoat'' wishes to be the next Creator/LeonardoDaVinci. He makes a lot of inventions in his spare time.
%%* William from ''WesternAnimation/{{Gawayn}}''.
* Kin Kujira from ''WesternAnimation/{{Grojband}}'' is very nifty with gizmos and gadgets, creating machinery ranging from robots to time machines.
* The Old Gummies in ''WesternAnimation/GummiBears'' made such advanced technology (including a complex underground road system and interoceanic communication devices in the Middle Ages) that they became a target for humans due to it.
* Froggo from ''WesternAnimation/{{Histeria}}'' is always asking for things because, as he puts it, "You've got your inventions, and I've got mine."
* Kai from ''WesternAnimation/TheHollow'' is able to get himself and his team out of a desert by building an airplane using the Four Horsemen's junkyard.
* ''WesternAnimation/InspectorGadget'': Professor Von Slickstein, who even incorporated gadgets into the title character's body.
%%** The Inspector's niece and dog, Penny and Brain, are the more competent gadgeteers, though they are just as likely to become the DamselInDistress (both of them are subject) or WronglyAccused (Brain, while simultaneously being the Damsel sometimes) while Gadget plays the SpannerInTheWorks. (Administrivia/ZeroContextExample; DamselAndDistress and WronglyAccused likeliness doesn't explain why they actually fit the trope.)
* ''WesternAnimation/{{Jingaroo}}'' has Toot and Snoot Groote, a pair of marspial moles who are particularly adept at mechanical engineering.
* Ernest the Kiwi from ''WesternAnimation/TheJungleBunch'' is capable of building massive machines. Though these machines tend to become a danger to the jungle that The Jungle Bunch have to deal with.
* ''WesternAnimation/{{Kaeloo}}'':
** Mr. Cat builds random gadgets when necessary, such as a cloning machine, and is also able to fix things (including a damaged time machine).
** [[RobotMaster Olaf]] has his own robot slave, and over the course of the show builds [[spoiler:an army of MechaMooks]] and [[spoiler:a FreezeRay]] and [[spoiler:turns Stumpy into a {{cyborg}}]].
* ''WesternAnimation/KimPossible'':
** Wade is able to build more or less anything that the plot demands, and he's just 10 years old.
** The Tweebs, who are the same age as Wade, are able to really pimp Kim's [[CoolCar car]].
** On the villainous side, Motor Ed is a mechanical genius. [[VerbalTic Seriously!]]
** In [[SuperpoweredEvilSide his "bad boy" mode]], Ron Stoppable is this. It's even latent in his "good" mode, when he builds a weapon (at Drakken's insistence) [[MacGyvering IN A LAIR, from A BOX OF SCRAPS]]!
* The ''Franchise/LooneyTunes'' franchise: In ''WesternAnimation/LoonaticsUnleashed'', Tech E. Coyote manages to cobble together a model of the city in his spare time. This model comes complete with trains that actually run on time. When ''not'' in his spare time, he makes the heroes' arsenal.
%%** ''WesternAnimation/LooneyTunes''' Wile E. Coyote tinkers on occasion, though mostly he uses AcmeProducts. (Administrivia/ZeroContextExample; specify one of these occasions?)
%%** Same with Calamity Coyote from ''WesternAnimation/TinyToonAdventures''.
* In the Creator/RubySpears ''WesternAnimation/{{Mega Man|RubySpears}}'' show, Roll modifies her Utility Arm herself. This includes such appliances as a vacuum, a blender, a circular saw, and ''modifying a baking sensor to detect earthquakes''.
* Coop from ''WesternAnimation/MegasXLR'' tuned up a HumongousMecha until it worked better than the original, even despite all the parts he keeps breaking on account of [[GeniusDitz not being all that bright besides]].
* Tanya from ''WesternAnimation/MightyDucksTheAnimatedSeries'' is introduced as, "She was so smart, she actually knew how to program a timer on a VCR!" As well as building the team's machines and [[StuffBlowingUp blowing up those of the enemy]], she uses a wrist-mounted [[ChainsawGood chainsaw]] in battle. She also has a stutter due to her brain going so fast (and trying to explain things in terms the others can understand).
* ''WesternAnimation/MollyOfDenali'': Walter has a gift for working with machines.
* ''WesternAnimation/MoonGirlAndDevilDinosaur2023'': Lunella has several inventions under her belt: such as the temporal vortex generator that brought Devil to the Big Apple, and has incorporated several into her Moon Girl costume; such as a jet pack made from fans, a pair of shoes that double as rollerskates equipped with retractable metal claws to kick in windows, a squirt gun that blasts liquid that traps foes in large blue bubbles, and her signature red boxing glove launchers.
* ''WesternAnimation/{{Motorcity}}'':
** Tennie, who even built the home she and her father live in.
** [[CoolOldGuy Jacob]] is this as well, having invented the Utility Bots.
** Dutch is a mechanic and engineer, usually repairing the Burners' cars, and building robots like R.O.T.H.
* ''WesternAnimation/MyLifeAsATeenageRobot'': Ms. Wakeman. She built the protagonist herself.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** [[CloudCuckooLander Pinkie Pie]], despite possibly being completely insane, has built a [[Creator/LeonardoDaVinci DaVinci-ish]] flying machine, a "[[ItMakesSenseInContext Welcoming Machine]]", and her signature party cannon... which she (except for one occasion) successfully uses to ''literally'' decorate for parties.
** The Flim Flam Brothers have the Super Speedy Cider Squeezy 6000 from [[Recap/MyLittlePonyFriendshipIsMagicS2E15TheSuperSpeedyCiderSqueezy6000 the episode of the same name]], which looks years more advanced than anything else that's ever popped up in Equestria.
* Dinko from ''WesternAnimation/PetAlien'' comes from a [[PlanetOfHats species of aliens]] known for their technical knowhow. He's made countless inventions out of the junk lying around Tommy's lighthouse.
* ''WesternAnimation/PhineasAndFerb'':
** Phineas and Ferb. Ferb does most of the engineering for their projects, but Phineas is quite handy with tools as well.
** Dr. Heinz Doofenshmirtz. Despite being a normally HarmlessVillain, he is capable of building -inators that are as impressive as the inventions of the title characters.
** The Fireside Girls, led by Isabella. They're usually just helping the boys out, which is impressive in itself, but they ''can'' build a time machine.
* The Brain in ''WesternAnimation/PinkyAndTheBrain''. This is arguably his real strength. His many devices include a functional MobileSuitHuman and a mechanical arm that turns him into a star basketball player. He's also modified others' inventions to turn a ShrinkRay into a growth ray and make a tornado-proof suit much more... well, tornado-proof.
* Strudel from [[Creator/TheHub The Hub's]] ''[[WesternAnimation/PoundPuppies2010 Pound Puppies]]'' tends to make her inventions from discarded items and the occasional more sophisticated electronics she comes across.
* Professor Utonium from ''Franchise/ThePowerpuffGirls'' creates things like a supersuit or a giant robot or a car that can turn into a giant robot.
* Dr. Skelley, Sydney's mom from ''WesternAnimation/ReadyJetGo''. She knows all about robotics, engineering, and technology. She also holds a strong belief that robots are the future, and teaches the kids about the types of jobs robots have, like helping out at a grocery store, rescuing trapped animals during a flood, collecting comet dust samples, and exploring volcanoes on Mars. [[spoiler:She even rebuilds Jet's robot clone, Jet 2, at the end of the episode and makes him into a DoAnythingRobot.]] Now that is awesome.
* Gretchen Grundler from ''WesternAnimation/{{Recess}}''. Being the SmartGirl of the group, she's easily able to construct gadgets and devices if the need for them arises.
-->'''Gretchen:''' Oh, you could make lots of devices out of the spare parts out of your family's garage. Why, I once fashioned a particle accelerator out of a broken hair dryer and a four slice toaster oven.
* The Geek from ''WesternAnimation/SamAndMaxFreelancePolice'' fits the original mold perfectly, as a young genius girl who built a gigantic robot Max in her underground lair.
* In ''WesternAnimation/TheSecretWorldOfSantaClaus'', Jordi always comes up with new toys and gadgets for Santa. They often malfunction, but they are also often a great help.
* Handy in ''WesternAnimation/TheSmurfs1981'' is capable of making all sorts of advanced machinery like harvesting machines, telephone lines, a fire pump, and even a robot in the Middle Ages.
* ''WesternAnimation/TheSpectacularSpiderMan'' has two:
** Adrian Toomes is the inventor of the Magnetic Air Transport System, a suit of {{flight}}-capable PoweredArmor that he uses as the {{Supervillain}} Vulture to antagonize Norman Osborn for stealing his designs.
** Chameleon's henchman Mason (aka, the Tinkerer) is responsible for developing all the ShoePhone technology the Chameleon needs for his work as a MasterOfDisguise.
* In ''WesternAnimation/SpicyCity'', M&G technician Otaku uses his technological skills to extract the consciousness of prostitutes, and program them into being complacent as virtual sex programs.
* Sandy Cheeks from ''WesternAnimation/SpongeBobSquarePants'' is an accomplished inventor, especially in the later seasons.
* Crowbar from ''WesternAnimation/StarComTheUSSpaceForce'' is a whiz with machines, and some episodes have him cobble together devices to solve the problem of the week, such as jury-rigging a force field generator to protect [=StarCom=]'s vehicles from the effects of an EMP.
* ''WesternAnimation/StarTrekLowerDecks'', being part of Franchise/StarTrek, has plenty of gadgeteer geniuses and [[ScienceHero Science Heroes]], including main characters [[OmnidisciplinaryScientist D'Vana Tendi]] and engineering officer Sam Rutherford.
* ''WesternAnimation/StarWarsTheCloneWars'': In "[[Recap/StarWarsTheCloneWarsS1E18MysteryOfAThousandMoons Mystery of a Thousand Moons]]", Anakin and Obi-Wan meet a teenager named Jaybo Hood, who has reprogrammed a lot of abandoned battle droids to serve him.
* Gear from ''WesternAnimation/StaticShock'', who initially thinks that his power is [[WhatKindOfLamePowerIsHeartAnyway rather lame]]: "How am I supposed to fight supervillains, ''think'' them into submission? All I can be is your Mega-Mechanic." Which turns out to be a great way to fight supervillains.
* ''WesternAnimation/StevenUniverse'':
** Pearl at one point builds a nearly fully functional spaceship out of a bunch of junk Greg has lying in storage. Later on, she manages to repair an escape pod five thousand years more advanced than anything she's worked with before, and figures out how to use it to track Warp Pad usage.
** Peridot is also a major one, considering her [[FantasticCasteSystem role in Gem society]] is to be a technician/engineer.
%%* Ginger Snap from ''WesternAnimation/StrawberryShortcake''. (Administrivia/ZeroContextExample)
* Kani on ''WesternAnimation/SushiPack'' fits the bill, although others have tried to steal credit for her inventions on occasion.
* Razor from ''WesternAnimation/SWATKats'' is the primary force behind the eponymous duo's technology (though T-Bone occasionally demonstrates that he's no slouch at least when it comes to engines), and thus they make military salvage into a working supersonic jet that's armed to the teeth with all kinds of unique missiles. His knowledge has limits, however, as demonstrated in the last episode, when he despairs over fixing a broken radar jammer.
* Donatello from ''Franchise/TeenageMutantNinjaTurtles''. Considering that he's self taught, living in a sewer, and working mostly with scavanged junk, his inventing abilities are downright super-reptilian.
* Wheeljack, from ''Franchise/{{Transformers}}''. He created the Aerialbots and the Dinobots, and while some of his inventions don't quite work out in the [[StuffBlowingUp explode-y sense]], his fuel pump is in the right place. He also invents lots of useful things, like the Immobilizer, which works great until it blows up, and the Negavator, which works great until ''it'' blows up, and a bomb, which is supposed to blow up, so it definitely works great.
* ''WesternAnimation/{{Wakfu}}'''s Nox, a brilliant (if unsuccessful) clockmaker, had a bit of this going on before he went utterly crazy. And then he went on to prove just how scary an ''[[EvilGenius evil]]'' [[MadScientist Gadgeteer Genius]] could be.
* ''WesternAnimation/WhatsNewScoobyDoo'':
** Velma Dinkley produces a number of remarkably sophisticated pieces of equipment in her spare time.
** Fred makes [[SarcasmMode a few minor modifications]] to the Mystery Machine, such as equipping it to transform into a submarine at the press of a button.
* ''WesternAnimation/WildKratts'' has Aviva Corcovado, TheSmartGirl who is responsible for the creations of the Creature Power Suits, as well as many other useful creature-inspired inventions. Her arch-rival, Zach Varmitech, is a downplayed variant, since his Zachbots are used more for {{Mundane Utilit|y}}ies.
* Tobey from ''WesternAnimation/WordGirl'' is a 10-year-old kid who, in his spare time, builds giant robots to do his bidding.
* ''WesternAnimation/WowWowWubbzy'' had the pink {{Tomboy}} Widget, who tackles problems she (or at least one of her three friends) faces by building machines. They often backfire, but once in a while they actually work.
[[/folder]]

* ''WesternAnimation/TheIncredibles'':

* ''VideoGame/DevilMayCry5'' introduces Nico, a former gunsmith and the mechanic partner (and driver) of Nero responsible for the [[ArtificialLimbs Devil Breaker]] system. Some of these arms are simple, like the [[ShockAndAwe Overture, which simply lets out electric blasts]], and the [[WhipItGood Rawhide, which is a chain whip that can improve his Wire Snatch]], but some can give Nero a RocketPunch that he can '''ride on''' or abilities like turning his pistol into a ''railgun'' or ''even '''slowing down time itself.''''' Not that surprising for her as she uses pieces of defeated demons to make these for Nero. She also gives Dante [[spoiler:Dr. Faust, a literal magic '''hat''' that she made based on her father's research that uses red orbs as ammunition]].

* In ''LightNovel/ThePetGirlOfSakurasou'', [[{{Hikikomori}} Ryuunosuke]] develops most of Suiko's gadgets, including [[ArtificialIntelligence "Maid"]].

* Rin-Rin from ''LightNovel/SisterPrincess'' can build custom laptop computers overnight for pocket change, complete with her own hand-written operating system. She's also built an [[RobotMe android duplicate of herself]], but the poor thing [[TheVoiceless can't speak]] and is still [[CuteClumsyGirl a bit klutzy]] at household chores.

** If you're looking for a person example, Numbuh 2 would be the man. Once you get past his [[IncrediblyLamePun punny]] way of life, he is one of the KND's best of these, if not arguably the best. In fact, he's considered so good that when plenty of other scientist kids are kidnapped by the supposed "Splinter Cell", special interest is put into protecting him by putting him into hiding. As Numbuh One puts it, if they get their hands on Numbuh 2, they'll be able to build almost anything.
