->''"Why would a prototype be more efficient than the finished model? Did they think that Big Daddies being fast, flexible and capable of self-preservation was just not being fair on everyone else?"''
-->-- '''Yahtzee, discussing Videogame/{{BioShock 2}},''' ''WebAnimation/ZeroPunctuation''

A Super Prototype is a testbed version of some piece of technology -- like a HumongousMecha, SpaceFighter, or KillerRobot -- that is, for some reason, superior to the mass-produced version. A super prototype will have better weapons, stronger armor, and [[ArsonMurderAndJaywalking higher-quality speakers]] than the units rolling off the assembly line. Even when there aren't very many of whatever device was designed in the first place, the prototype model is almost always the most powerful, or has at least some advantage over the other models.

A question that often comes up is why the super prototype is so, well, super compared to the production model. The typical reason given is that the production model is far cheaper or easier to make in large numbers. Except that this defeats the whole purpose of a ''prototype'' - something built to test the capabilities of the final product and correct any flaws before mass production begins, meaning you want your test unit to be as similar to your production unit as possible. As such, real-life prototypes are frequently indistinguishable from standard models. Mostly, this is just a case of letting TheHero be [[UniquenessValue that much more awesome than everyone else]].

Writers tend to find various reasons for why the Prototype is better which usually fall under a few general lines of reasoning.

# A real-world concept that more closely resembles the super prototype is the ''experimental'' unit or "concept car," which is intended to test out new technology and its limits without ever being meant for mass production at all. As cost-effectiveness is less important, experimental units frequently ''do'' have superior performance to eventual mass production models. Military test pilots refer to this as "pushing the envelope" - the upper edge is height, the left edge is speed. Visualize this as the kind of envelope you mail somebody and you realize that particular area is [[IncrediblyLamePun where the postage gets canceled]]. In this instance a common flaw for the Hero to have is that because the prototype is meant for performance but not longevity, there are no proper safeguards in place to protect the user or others nearby. This can lead to a power overload or damage to the prototype and/or the hero, effectively giving them a whole load of {{DangerousForbiddenTechnique}}s, in addition to the experimental technology itself.
#A common fusion of the normally opposite tropes, SuperPrototype and FlawedPrototype, is "TheHero's version is more powerful but has the DramaPreservingHandicap that the others don't." Maybe all versions after TheHero's are weaker because the "use it for longer than [[HourOfPower five minutes]] and it shuts down/explodes/drives you insane" problem could not be fixed without losing some power. An alternate fusion introduces a prototype not of the current rank-and-file model, but their intended successor, as a justification. It would, of course, be equally workable for the hero to be less powerful but lack the handicap, but that's less popular.
#Another common version is when the prototype is made by a genius and [[NoPlansNoPrototypeNoBackup only they completely understand the technology behind it]]. Then the genius dies while the prototype goes missing. The bad guys may have the notes and schematics but the science is still not completely understood without getting back an studying the prototype. In this case, only weaker or imperfect versions of the prototype can be made. In this instance, one of the main motivations of the bad guys is to get back to prototype so they can study it and fill in the gaps to the process for perfectly recreating it. The hero must then keep it out of their hands at all costs.
#Lastly, the prototype may not be a prototype but instead BlackBox technology or if a prototype was made, black box technology was incorporated into the design and the "super" parts of the prototype are [[NoPlansNoPrototypeNoBackup unreplicable.]]

A closely related trope is the AceCustom. See also ReedRichardsIsUseless and BiggerStick. Related to (and often exists for the same narrative reasons as) the ConservationOfNinjutsu.

The {{Opposite Trope|s}} is the FlawedPrototype and SuperiorSuccessor. Technically. Since most prototypes have more than one attribute, overlap can occur where it has both flaws and superiorities. The PhlebotinumRebel usually is both, with superior abilities but inferior obedience, so it does not carry out the purposes it was made for.



[[folder:Anime & Manga]]
* The ''Franchise/{{Gundam}}'' metaseries makes extensive use of this trope. Pretty much any mecha with "Gundam" in its name will be either this, an AceCustom, or both. This is justified in-universe due to cost-effectiveness; the prototype usually carries a better reactor, armor, and weapons. Mass produced units based on these super prototypes tend to sport cheaper and inferior features (or the features are removed from the mass production unit altogether) so they can produce a lot more with same amount of budget and resources. The prototypes are also usually very goal-oriented, with each one being designed to test some new weapon, technology, or design technique. Additionally, most of the super prototypes remain superior only to their generation of Mobile Suits as technological race is a strong theme in the Gundam series; few suits that can hold their own against even the bog-standard suits of later generations. As a whole, the super protoype mobile suits are one-offs that spawn cheaper copies and are later discarded or destroyed. There are a few exceptions to this:
** In the original ''Anime/MobileSuitGundam'', while the RX-78-2 Gundam was intended to be a quantum leap over Zeon's Zaku II (hence its SuperPrototype status), it was also experimental in that the Earth Federation was still learning how to make a mobile suit at all. Some of the features were intended less for combat utility than to ensure that the testing data would be preserved (a "Learning Computer" that not only recorded even the most minute details of its performance but also analyzed the data in real-time, and an elaborate EscapePod that transformed into a functional jet fighter to maximize the odds of survival for the Learning Computer in the event of a disaster), and other elements simply couldn't be produced cheaply enough to justify inclusion in the mass-production RGM-79 GM. Thus, the GM lacked any escape pod at all, used ordinary titanium armor instead of the exotic "luna titanium" alloy that at the time could only be produced in a single laboratory, and carried a "beam spray gun" pistol that was equal in lethality to the Gundam's beam rifle but shorter-ranged and less accurate. And by the time the One Year War ended, Zeon's latest mass-production mobile suit, the Gelgoog, actually exceeded the Gundam's performance in all aspects except armor; at this point it was [[AcePilot Amuro Ray's own skills]] rather than the Gundam that made him nearly unstoppable in battle.
** ''Anime/MobileSuitVictoryGundam'' [[ZigZaggingTrope twists it]]. While the eponymous Victory Gundam is superior to its simplified sister model [[RedShirt Gun EZ]], the actual mass production model is identical to the prototype. The Victory 2 was meant to be a limited-production model, but the other suits were destroyed prior to being fielded, leaving Uso's V2 as a unique unit.
*** On the whole, ''Victory'' shows a more realistic deployment: In the beginning, the V-Gundam takes the Superiority Fighter role while the Gun EZ takes the workhorse role. Then, the V-Gundam is mass-produced as the V-Gundam Hexa and takes the workhorse role, with the V-Dash Gundam filling in the Superiority Fighter role until the V2 is ready, at which point the V-Dash takes on a Joint Support role, covering both the V-Hexa workhorses and the V2. The Gun EZ and Jamesgun are relegated to the gunship role held by the Ball in the One Year War.
** While it appears to be played straight in ''Anime/MobileSuitGundamSEED'', with the Strike Dagger being inferior to the Strike Gundam, [[AllThereInTheManual sidestories]] reveal that Strike Dagger is merely a stopgap production; the actual mass production model, the 105 Dagger, is superior to the Strike Gundam. Sure, it has limited laminate armor instead of full body PS armor, but with [[KryptoniteIsEverywhere pretty much every mobile suit using beam weaponry by that point]], the latter isn't as useful as it was.
*** The Astray line is an odd case. The colored Frames (Red, Blue, Gold, Green and Mirage) were all prototypes, but weren't anything incredible. It's only by the wonders of [[AceCustom their respective pilots customizing them]] that they became superior to the later mass produced M1 Astray units. And even then, the mass-produced Astrays could take on the prototypes, as the Red Frame was once easily taken down by a simple M1 Astray (granted one piloted by Coordinator).
*** However, ''Gundam SEED'' does play the trope straight with the Moebius mobile armor. The Moebius Zero prototype sports four detachable and independently maneuverable gun barrels in a precursor to the DRAGOON system later used to great effect by certain BiggerStick mecha like the Providence; the production model Moebius lacks these, using only the forward-fixed central cannon. This is {{justified|Trope}} in that only a select few OMNI pilots had the spatial awareness and piloting skills required to use the detachable gun barrels effectively, and of those pilots very few (we basically know of Mu la Flaga only) survived the Battle of Endymion prior to the start of the anime, so paring down the design was an unfortunate necessity.
*** The [=GuAIZ=] Experimental Firearms Type mounted the same weaponry as both the Freedom and the Justice, but was scaled back to the basics for the production model because it was incredibly expensive to maintain. The production models were massively scaled back because, at the time, it was near the closing moments of the war and the standard weaponry was deemed good enough (and it was, as the [=GuAIZ=] was one of the most powerful production mobile suits to be used during the war). Unfortunately both suffered a case of SoLastSeason when the new ZAKU Warriors proved to be superior and cheaper. Especially compared to the [=GuAIZ=]-R version that was introduced as a stopgap before the ZAKU Warrior, with scaled-down weapons and performance both to cut costs and because the "Extensional Arrestor" weapons (a combined rocket anchor, beam dagger and beam gun) that was so devastating in combat at the Battle of GENESIS proved impossible for all but the most elite pilots to control.
*** The ZAKU Warrior is another inversion as its prototype, the ZAKU Trial Type, had no beam weaponry despite having an N-Jammer Canceller-outfitted nuclear engine. The ZAKU Trial Type was intended for mass production, but the [[PeaceConference Treaty of Junius]] banned the military use of N-Jammer Cancellers and thus the design was reworked. The addition of superior weapons is probably explained by the extra couple of years of development.
*** The Extended 'Biological CPU' introduced in Gundam SEED is superior to the Extended introduced later in Gundam SEED Destiny, as they were able to pressure even high-end Coordinators like Kira and Athrun in combat. At the same time, they're also [[FlawedPrototype Flawed]] and PsychoPrototype, and compared to them, the Extended in SEED Destiny are practically bastions of mental stability.
** ''Anime/AfterWarGundamX'' initially {{avert|edTrope}}s this, with the prologue showing that the titular Gundam (as well as the Airmaster and Leopard) was mass produced, and Garrod's is simply the [[LastOfHisKind last of its kind]]. [[spoiler:At least until the United Nations Earth recovers Jamil's old Gundam X and upgrades it into the Double X.]]
*** The [[ThoseTwoBadGuys Frost Brothers]]' [[NamesToRunAwayFromReallyFast Virsago and Ashtaron]] seem to play this straight, but the ''VideoGame/SDGundamGGeneration'' series gave them their '''own''' Super Prototype: the Gundam Belphagor, a contemporary of the GX, Airmaster, and Leopard. Instead, the Virsago and Ashtaron essentially split the Belphagor's gimmicks in half and develop them in their own direction.
** It's also noteworthy that in ''Anime/MobileSuitZetaGundam'' this trope becomes the shtick of Paptimus Scirocco. Over the course of the series he cranks out one-shot, scratch-built mobile suits at an astonishing rate. The Messala, Pallas Athena, Bolinoak Samaan and The-O are all unique Scirocco designs, while the Gabthley and Hambrabi are limited production models designed by Scirocco for the Federation's use and only 2-4 of each were ever made. In general, Scirocco's godlike ability to crank out butt-kicking mobile suits is used as a catch-all explanation for all Titans suits that aren't the Psyco Gundam.
*** And the Gundam Mk-II actually inverts this - even though it was a Super Prototype for the next generation of MS and, for awhile, could one-up the Titans' Hi-Zack units(current generation), there was nothing special about it outside of its special lighter frame system and it's easily outclassed early on. All it really is is an updated copy of the original RX-78 Gundam made using modern technologies, and thus ceased to be anything special when those same new technologies were incorporated into the new generation of mass-produced mobile suits.
*** ''Anime/MobileSuitGundam0083StardustMemory'' has a similar inversion with the Gundam [=GP01=] "Zephyrantes", which was little more than an update to the original Gundam with new tech, it comes with the ground type and space type configuration, which is more powerful than the mass production model of the time at its specialized area but weaker when placed in the other, so it is just an exchange of spec instead of "Super" in all aspects. In fact, the proposed Gundam [=GP04=] "Gerbera" was scrapped for being little more than a copy of the [=GP01=]; it was later reworked into a more Zeon-esque design, the Gerbera Tetra, and [[PlayingBothSides sold to the Zeon remnants]].
** Some of the U.C. super prototypes are depicted as being advanced for their era but [[FlawedPrototype with crippling flaws]] that are usually the result of being developed to field test a particular technology with little consideration to anything else:
*** The MSN-00100 Hyaku Shiki from the aforementioned ''Zeta Gundam'' was designed to test out beam-resistant armor and the concept of the [[TransformingMecha Moveable Frame]]. The beam-resistant armor worked. The transformation feature did not. But the moveable wing binders left on the unit did improve the mobility of it.
*** The [[Anime/MobileSuitGundamZZ MSN-010 Double Zeta]] is a massive power-house that can transform into a mobile armor, has two of the biggest beam sabers in all of Gundam, and its [[WaveMotionGun high mega cannon]] is powerful enough to turn any opposing Mobile Suits into little more than drops of melted steel. Unfortunately the high mega cannon drains almost all of its power supply ''in one shot'', and its over-complicated transforming frame makes it structurally weak, turning it into something of a GlassCannon.
*** The [[Anime/MobileSuitGundamUnicorn RX-0 Unicorn Gundam]] has psychoframes built into its entire structure. When these activate, it's an [[TheBerserker unstoppable killing machine]] with [[LightningBruiser amazing speed]] that can [[HackYourEnemy hijack enemy-controlled psychoframes]]--for five minutes. Until the psychoframes go active, it's just a slightly-above-average MS with two beam sabers and one [[{{BFG}} beam magnum]] (with only 15 shots).
** The Tallgeese in ''[[Anime/MobileSuitGundamWing Gundam Wing]]'' was the precursor to all mobile suits in that universe. It's so powerful it can hold its own against the first generation of Gundams in that series. It did have one glaring design flaw: it was so powerful that it ''killed its own pilots''. This was because the Tallgeese effectively had no shock absorbers; its gargantuan size and incredible thrusters transferred ''all of the G-Force'' to the pilot. The Leos that were based on its design are far weaker but also safer for people to pilot. The Wing Zero is, likewise, a super prototype to the Gundams, as it housed the dangerous ZERO System, which fed real-time tactical data directly into the minds of its pilot. Unfortunately unless you actually ''know'' how to process that data, it just drives you insane. The comparatively downsized Gundams each just settled for unique weapons tacked on to the general frame. Note that the Wing Zero was specifically designed to counter the Tallgeese.
** There's also some speculation that the Wing Zero may have '''''EATEN''''' one of the pilots who attempted to use it. Because despite the pilot being declared dead and the cockpit never opening after his death until Zechs captured it, they NeverFoundTheBody afterwards, which not only means the suit is dangerous to the mind of the pilots, it may have actually gotten a taste for [[ImaHumanitarian human flesh]]. The fact that Heero ''talks'' to Zero like it can actually communicate with him, and tells Zechs that both Zero and Epyon have "told" him things just makes the ZERO system itself NightmareFuel on several levels.
** The Vayeate and Mercurius from ''[[Anime/MobileSuitGundamWing Gundam Wing]]'' was this to the mass production Virgos. However this was due to both of the mobile suits being test beds for their respective systems; the Vayeate needed an external reactor to power it's beam cannon while the Mercurius had to dedicate all of it's power to the "Planet Defensors", leaving it with very little offensive capability beyond a beam saber-shield. The Virgo was designed to be something in-between; housing less than a quarter of the Mercurius' Planet Defensors so that it can wield a less powerful version of the Vayeate's Beam Cannon. This was acceptable, as the Virgo was to be mass produced and unmanned, so what they lacked in quality they made up for in overwhelming quantity. In fact when the two prototype suits were later rebuilt as unmanned Mobile Dolls as well, they fared much less effectively against the Gundams, as they were only marginally more effective, but there was only two of them compared to the dozens of Virgos flying around.
** ''[[Anime/MobileSuitGundamThe08thMSTeam The 08th MS Team]]'' actually averts this. The series is known for instead of making a traditional Gundam series about a boy FallingIntoTheCockpit and getting involved in the current war, and instead focuses on the everyday soldiers in the One Year War. Because of this, most pilots in the series don't have brand-new prototype Mobile Suits. Instead they have things like the RX-79(G) Gundam Ground Type, which is merely spare parts from the RX-78 Gundam program made into a mass-produced Gundam designed for ground combat. There's also the Gundam Ez8, which is an RX-79(G) rebuilt with field-fabricated parts due to lack of spares. One poor unit even had its destroyed head replaced with that of a GM. Still, the Ground Type Gundam's run was limited to about 20 units, with its GM counterpart, the RGM-79(G), only having 42 base units and a handful of Sniper variants built. That said, according to side materials the ground-type GM does have some Super Prototype-esque features over the standard GM - for one, it's still made out of the rarer and more durable luna titanium the original Gundam uses, rather than the standard GM's lighter but weaker titanium alloy. It's also compatible with a full-sized, full-power beam rifle, rather than the smaller and weaker "beam spray gun" the standard GM uses... though beam rifles were in such short supply that most examples of both the Gundam and GM Ground Type carried less powerful projectile-firing machine guns instead.
** ''Anime/MobileSuitGundamF91'''s eponymous Mobile Suit (the Formula 91) plays with this; its prequel manga features the F91's predecessor (the [[http://gundam.wikia.com/wiki/F90_Gundam_F90 Formula 90]]), of which two were made. The F90s sported multiple hardpoints all over their chassis which [[MechaExpansionPack could be outfitted with different equipment]], resulting in eight specialized configurations (later model line and settings expanded the equipment up to 26 different packs). S.N.R.I. (the company responsible for the Formula Project) then used the combat data from each configuration and built the F91 using optimized versions of the most effective and well-rounded F90 variant (namely the [[http://gundam.wikia.com/wiki/F90V_Gundam_F90_VSBR_Type F90V]]). The F91 was later subject to limited mass production, though no changes were made to the mass produced units from the original F91. So in essence the F91 is only a super prototype in regards to the previous Formula Gundam, with its mass-produced equivalents being almost carbon copies, with the exception of the locked overdrive mode of its Bio-computer which over-heats the unit(but gives it a short performance boost) and fixed the paint shredding flaw(which gave the prototype a strange ability of splitting into mutiple images in the enemy screen).
** On the Zeon side, the line between Super Prototype and AceCustom is heavily blurred, because [[InterserviceRivalry Zeon's MS design companies are all competing with each other in midwar]] to build the next generation of ''wunderwaffen'', and very few prototypes actually pan out. However, Char Aznable's MS-14S Gelgoog, the prototype for the Gelgoog line, was faster ([[FragileSpeedster though less well-armored]]) than the mass-produced MS-14A model.
** ''Anime/MobileSuitGundam00'' is very much this case, particularly with the Gundams of Celestial Being, and the more specialized units of the Earth Sphere Federation's A-Laws, and Innovade allies. Each of the main Gundams have a specific role, such as Sniper, Melee, Aerial Assault, or Heavy Artillery [[spoiler: Which secretly hides it's real purpose, as a judge, jury, and executioner for those who betray Celestial Being's ideals with a system that shuts down rogue Gundams systems]]. Several side story visual novels and mangas also detail the prototypes to the Gundams of the anime, and [[MechaExpansionPack Mecha Expansion Packs]] that were never seen in the show, due to their limited purposes.
*** Extended even further, with it's BlackBox tech centered round it's GN Drives. To create a true GN drive, is a time and resource consuming and somewhat dangerous process, as in order to make a critical component, the Topological Defect Blanket, or TD Blanket for short,[[note]]This component allows Gundams to harness the power of Topological Defects giving them nearly unlimited power supply, and produces the greenish/blue GN particles.[[/note]] requires a dive into Jupiter's upper atmosphere to collect the materials needed. After 200 years of working in secret before publicly announcing their presence to the world, Celestial Being manged to produce a total of 5 GN Drives, and is indeed, considered more valuable than the Gundams themselves. It takes two years for Celestial Being after the events of the anime, and leading to the start of Anime/Gundam00AWakeningOfTheTrailblazer, to make two brand new GN Drives specially designed for the new 00 Qan[T], and is remarked upon by several characters that was considered to be ''fast''. It takes another 50 years according at the end of the movie, for Earth as a whole to be able to start mass producing True GN Drives, and not the GN Tau Drives they've been using.
** ''Anime/MobileSuitGundamIronBloodedOrphans'' features two Super Prototypes:
*** The EB-05s [[GratuitousGerman Schwalbe Graze]] (lit. Swallow Graze) is a prototype of the mass produced Graze, however, being experimental weapon, they're modified to have multiple boosters to amplify its aerial combat, equipped with wire claw, as well as a rifle lance. It earns its reputation as AceCustom for high rank officers.
*** The V08-1228 Grimgerde is one of the nine Valkyrie Mobile Suits developed by Gjallarhorn in Pre-Calamity War, Grimgerde serves as the prototype of the mass produced Graze as well as the Graze Swords carried by Carta Issue. Piloted by masked man [[CharClone Montag]], he assists Tekkadan in overthrowing the current leader of Gjallarhorn.
*** The Gundam Frames units, unlike the traditions, are 72 limited production units featuring twin Ahab Reactors.
* Chi and Freya from ''Manga/{{Chobits}}'' were two of the first persocoms ever built, yet their capabilities exceed any that were built after them.
* ''Anime/{{Macross}}'' usually averts this, with the production models being built up from the prototype's capabilities. Even prequel ''Anime/MacrossZero'' only uses a FlawedPrototype in the form of the VF-0 Phoenix: despite having flight performance head-and-shoulders above conventional jet aircraft and even limited capability for ''underwater operation'', it's a maintenance-hog and the war's outbreak meant that the engineers couldn't wait until the intended space-capable reactor engines were completed so they simply slapped on the strongest air-breathing jet engine they could get their hands on and crossed their fingers.
** The majority of ''Anime/MacrossPlus'' consists of a contest between two super prototypes (YF-19 and YF-21) competing to be the new mass production model; they eventually choose the YF-19 after the YF-21's UnusualUserInterface proves to be [[SarcasmMode a little unsafe if the pilot gets distracted during flight]]; the [[spoiler:destruction of the YF-21 prototype]] doesn't help either. This is actually a realistic portrayal of the prototyping system; similar contests have actually occurred in real life.
** The VF-25 the good guys use in ''Anime/MacrossFrontier'' also has superior performance to the military standard-issue VF-171 along with a redesigned Armored Pack that won't lock the Valkyrie into battroid mode; while the civilian protagonist recognizes it on sight, it's confirmed as still undergoing official performance evaluations.
*** {{The Movie}}s both subvert this, and then play it straight. The Tornado Pack is noted to be AwesomeButImpractical, itself the FlawedPrototype to Alto's [[MidSeasonUpgrade YF-29 Durandal]], whichi is pretty much confirmed to be the most advanced fighter craft in the ''Macross''-verse at that date. Even then, its bright red color scheme is noted to be because of its status as a prototype, and not [[LawOfChromaticSuperiority the other reason.]]
* In a way, [[spoiler:Madara Uchiha]] and [[GreenThumb Hashirama Senju]] are this compared to most ninja in the ''Manga/{{Naruto}}'' universe. Due to living in an age of constant warfare, their abilities were brought to such a zenith that, as Kabuto Yakushi described, many people ''thought it was a fairy tale'', specifically Hashirama. We've seen characters like Yamato, Danzo, even [[spoiler: [[BigBad Tobi]]]] with Mokuton which doesn't remotely ''compare'' to Hashirama, and Sasuke and Itachi both achieved the same [[DeadlyUpgrade Mangekyo Sharingan]] powers as [[spoiler:Madara]], specifically the PoweredArmor, [[NighInvulnerability Made of Diamond]] [[InstantArmor Susnao'o]], but [[spoiler:Madara's Susano'o is on such a ''far higher scale'' than both ''combined'', Tsunade, one of the current Kages and one of the most powerful shinobi of her era, wondered ''how the fuck did her grandfather even fight Madara''?]]
** [[spoiler:And the Biju themselves, even ''Kurama'' are far weaker than the original Biju, the Shinju or "God Tree" which is in itself the Ten-Tails.]]
* ''Manga/OnePiece'' has the World Government-developed Pacifistas. The original, created by [[WeCanRebuildHim rebuilding]] Bartholemew Kuma into a {{Cyborg}}, is able to make short work of some later models, though this is mostly because Kuma had Devil Fruit powers that apparently couldn't be transferred to the others or technologically duplicated. [[spoiler:It is stated that more powerful models have been created over the TimeSkip, though it has not yet been shown how well Kuma would stack up against them.]]
** Another example would be the sea train in Water 7, the original one, Rocket Man, is WAY faster than it's successor, but it wasn't used as the city's train since it's extreme speed, lack of breaks, lack of steering controls and lack of momentum (if it crashed something it wouldn't lose speed but it would be sent flying in any other direction) was a high risk to safety for something meant to be a civilian train.
** An aversion is implied with the ancient weapon Pluto; the government's "official" explanation in regards to it is that they either erase any chance of someone using it ever, or get the blueprints for it so they can make their own just in case, which implies that at the very least, they think they have the resources, manpower and skill needed to make/mass produce a model as good as the original just as long as they get the how.
* The police protagonists on ''Manga/{{Patlabor}}'' had three prototype AV-98 Ingram mechs. One episode focused on the introduction of a mass-produced line of Ingrams, subverting the trope a bit in that the prototypes weren't exceptionally good so much as the mass-produced ones were exceptionally shoddy. Also, other kinds of mass-produced police and military mechs are shown to be close in quality to the Ingrams.
** The first film has the Type Zero which was supposed to be an advanced replacement for the AV-98. It proved to be a fearsome opponent in melee combat against other labors and when it was overtaken by the Babel virus, it completely mopped the floor with Ohta's Ingram and Noa barely managed to subdue it. Seeing as the Type Zero wasn't seen in the subsequent films, it can be assumed that the design was abandoned.
* One character from ''Franchise/LyricalNanoha'', [[spoiler:Subaru Nakajima]] is a self-admitted homage to ''VideoGame/SuperRobotWars''. [[spoiler:It turns out that she]] is the prototype to the Number cyborgs, [[spoiler:as is her sister Ginga]], and while she's not technically stronger than the Number cyborgs, she does have an Inherent Skill that is very effective against cyborgs. The special moves "borrowed" from such {{Super Robot|Genre}}s like ''Anime/GEARFighterDendoh'', ''Anime/GaoGaiGar'', ''Manga/CombattlerV'' and more make this homage especially apparent.
** Fate Testarossa is another super prototype in a way -- she was [[spoiler:the very first successful ArtificialHuman created by an illegal cloning project run by the master of the Numbers, Jail Scaglietti. She bears the project's original name, and is the prototype that Jail used to create all the other Artificial Mages of the setting]]. However, to her mother, Fate is a FlawedPrototype because [[spoiler:she was meant to be a clone of her dead daughter Alicia, but ended up gaining quirks of her own, which royally pissed off mommy dearest.]]
* Played with in several different ways in ''Manga/CombatMechaXabungle''. The titular mecha (''referred to as such'' by the regularly no-fourth-wall characters) is both a production model--the protagonists get ''two'' of them, unheard of in a mecha show up to that point. The Xabungles are also a prototype in the sense that no prior Walker Machine is built specifically for combat (hence the series name--Combat Mecha) and they incorporate a number of features that imply they're space-capable. The Walker Gallier in the second half of the show is a textbook example (and even has a production model of sorts in the Brackary). It's famously "Super" enough to ''[[CatchAndReturn catch and throw]]'' a falling ICBM (albeit a museum copy, but still).
* Ram-Dass in ''Anime/StrainStrategicArmoredInfantry'' is an illegally made mecha where the Union only condones standard issue. Because Sara saved them in it, it's explained away as a "prototype" to anyone that asks. Her brother's Gloire, on the other hand, is an AceCustom.
* Remarked upon in ''Anime/TengenToppaGurrenLagann'', in reference to the [[SpellMyNameWithAnS Grappals/Gulaparls]] compared to the Gurren Lagann:
-->'''Gimi:''' Anyway, aren't Grappals supposed to be superior to Gurren Lagann? There's something wrong with a prototype being stronger.
** The trick here wasn't intentionally dumbing down the mass-produced version but rather the designers being ignorant of one crucial fact: the Gurren Lagann, like all Ganmen, is an EmpathicWeapon. Simply copying the machinery won't help if they don't know what makes it tick. Once this fact is discovered, they quick-fix the situation with the addition of Spiral weaponry but they're still nowhere near enough [[RealityWarper Ganmen territory]].
** As seen in the movies, if your will is high enough, even the mass production models can grow into galaxy sized bots, a la "Tengen Toppa Grappal/Gulaparl" and fire planet system-sized shotgun rounds.
* ''Anime/CodeGeass'' features several super prototypes, [[LensmanArmsRace progressing in power with the times.]] Supplementary materials explain the backstory of KMF development, where they were literally putting pieces together just to see how it worked.
** The best subversion of this trope is the Ganymede, the earliest-built Knightmare to be shown in the series (3rd Generation). It has no internal power source, only batteries; no weapons, no closed cockpit and insufficient motive power to do anything other than harmlessly cruising. [[MundaneUtility It can make the world's biggest pizza, though.]]
*** This is actually a Double Subversion. The Ganymede model was indeed the Super Prototype of its day, being a powerful mecha in the right hands. These hands being those of [[SilkHidingSteel Marianne vi Britannia,]] nicknamed [[RedBaron "the Flash"]] for her incredible skill with the Ganymede, rivalling the later [[TheDragon Knight of One,]] Bismarck Waldstein [[spoiler:who used his [[MagicalEye Geass]] to cheat, [[NoSell and STILL lost to Marianne.]]]] After Marianne's death, the Ganymede, being her signature Knightmare, fell out of favour and was decommissioned, having its weaponry removed and returned to the manufacturers, the Ashford Academy.
** Another [[FlawedPrototype subversion]] is the Gawain; when Lelouch jacked it, it was an AwesomeButImpractical KMF. It could fly, but a flaw in the hadron cannons left the beam unfocused, causing it to spew energy in a wide arc which could just as easily hit friend as well as foe. That problem was fixed, making the beams extremely deadly, but it was still outmatched in close combat. Its mass-production version, the Gareth, had the cannons moved it its hands.
** To a smaller extent, the Vincent: the Vincent Ward final version scraps the needle blazer weapon to ease production. Also Vincent's own Super Prototype, the Lancelot: the world's first seventh-generation KMF, later upgraded into the one-of-a-kind ninth-generation unholy terror known as the [[AceCustom Lancelot Albion]].
** On the opposite side of the coin, Guren Nishiki gets two successors: the limited-production Gekka and the mass-production Akatsuki (as well as Tohdoh's [[AceCustom Zangetsu]]). Neither can hold a candle to the original, especially after it receives its own ninth-gen upgrade into the Guren SEITEN.
*** That said, this may be due to the pilot, but no direct comparison is made between the Guren's abilities and any of it's MP derivatives. Also, the Prototype Radiation Arm used by the Guren Nishiki after it's original Radiation Arm is destroyed seems to be both weaker, and not as well built, but this is also difficult to compare.
* Appears as an UnbuiltTrope in ''Anime/MazingerZ'', the archetypal {{Super Robot|Genre}} series. Mazinger Z was lacking a lot of its special features at first and regularly had to be upgraded and re-outfitted with new equipment. At the same time, the manga introduced the Mazinger Army, a trio of weaker robots each designed to wield one of Mazinger's distinctive weapons. All three made minor appearances in the ''Anime/{{Mazinkaiser}}'' movie, and [[spoiler:all three were destroyed, with only Million Alpha putting up any kind of a fight]].
** Averted in, of all things, ''Anime/GreatMazinger'' -- the Mikene Empire get a hold of Great's plans and mass produce it perfectly (with the exception of its wings). They usually show up in any ''VideoGame/SuperRobotWars'' installment when the ''Great Mazinger'' storyline is used.
** And it was also averted in ''Anime/{{Mazinkaiser}}'': Shin Great Mazinger and Mazinkaiser are explicitly stated to be the finished models, their predecessors are the prototypes.
** And averted in ''Anime/ShinMazinger'' as Energer-Z was able to go toe to toe with Mazinger-Z.
* ''Anime/NeonGenesisEvangelion'' does strange things with this trope. Units 00, 01, and 02 are referred to as the prototype unit, test unit, and production unit, respectively, but they're functionally identical in operation. ''End of Evangelion'' features "mass produced Evas" that are superior in basically every way, but aren't really a refinement of the original Evas so much as the same underlying technology taken in a different direction.
** ''Anime/RebuildOfEvangelion'' gives us Provisional Unit-05 which is very much a FlawedPrototype, as it was rushed into service half-built to deal with an emergency situation. The only advantage it had over any other Evas were the flight thrusters. The third ''Rebuild'' movie subverts the trope by introducing even later Eva Units that are far superior to the prototypes they'd been using: with modular weapons packs that can quickly be swapped out mid-battle, portable batteries allowing them to operate without the umbilical cable, and the Eva Mark-09 has rocket boosters that allow it to fly under its own power and an Angel-level HealingFactor. [[spoiler:Unit-13 appears to be Unit-01's successor and has AttackDrones and two sets of arms, in addition to Unit-01's ability to initiate an Impact Event under the right circumstances.]]
* ''Anime/SkyGirls'' features this: The three original Sonic Divers are prototypes, and they do their job well. Subverted in the fact that the mass production model can do just as well, but the WORM attacks the production assembly plant, making the only one model that was completed a super prototype in its own way.
** Also used straight when the [[spoiler:[[VideoGame/{{Gradius}} Vic Vipers]]]] make their debut, it is marketed as cheap, much better and more heavily-armed alternative to the Sonic Divers that the titular characters use, and hence, is mass-produced. Not only it really is underperforming in comparison, the best thing it can do is act as support rather than replacement. It actually even gets beaten by an old, conventional fighter piloted by the show's TheAce in the end, and ''it's a two-against-one battle''.
* ''Manga/MetalArmorDragonar'' plays with this a bit. The beginning of the series shows the Dragonars as a set of stolen super prototype units, but their pilots are inexperienced, and the AceCustom units trounce them frequently. After a while, the Dragonars are used as the template for a new Mass Production model that has specs stronger than any of the Dragonar units. However, after Professor Plato guides the heroes back to the military, the Dragonars are upgraded into Ace Custom Super Prototypes.
* Pretty much the only mechs that accomplish anything important in ''Anime/EurekaSeven'' are super prototypes, with the two Nirvash (which are actually ''[[EmpathicWeapon alive]]'') units being the most prominent. There's also Holland's late-series mount, the TB-303 Devilfish, which is ridiculously powerful and has enough firepower to wipe out multiple capital ships, but requires the pilot to take life-threatening drugs to operate it... Aside from those, the rest of the powerful LFO's are all {{Ace Custom}}s. Anything with "KLF" or "Mon-Soono" in its name is [[MechaMooks utter cannon fodder]].
* Sagara Sousuke of ''LightNovel/FullMetalPanic'' handles the [[http://img.photobucket.com/albums/v629/Kuruni/MS-Story/Vault-Other/arx-7.jpg ARX-7 Arbalest]], one of the first mecha to be fielded by MITHRIL to possess a Lambda Driver. Later in the series he goes up against many enemy mecha with Lambda Drivers of their own, but proves his to be the more powerful while defeating them in combat. It is suggested that this is because the Lambda Driver in Sousuke's mecha is a prototype model compared to the mass-produced variants fielded by the enemy, and is capable of increased output at the cost of stability. It does, indeed, fail to function properly on a number of occasions, leading Sousuke to become thoroughly frustrated with it. Said Lambda Driver is later put into the ARX-8 Laevatein which, despite the serial number, is actually an AceCustom put together in a hurry. It can still kick the asses of everything mass-produced, though.
* Zigzagged in ''Anime/VipersCreed'': in the last episode we see a prototype white mech with greater speed, armor and two additional arms; but its software is not optimized, so at critical moments it freezes from bugs.
* Played straight in ''Manga/OutlawStar''. The [=XGP15A-II=] was purpose built using advanced military tech for the purpose of reaching the Galactic Leyline.
* [[RidiculouslyHumanRobots Chachamaru]] of ''Manga/MahouSenseiNegima'', the first of [[MadScientist Hakase, Chao, and the engineering club's]] line of androids, which Chachamaru refers to as her little brothers and sisters. As [[ChineseGirl Ku Fei]] mentioned before she kicked the asses of multiple mass-production versions of Chachamaru at once, as long as it's not Chachamaru herself, the fight is easy.
* Clamp managed to do this in an episode of ''Manga/AngelicLayer'' to the titular toys when the design team unleashed against the tourney players a new prototype model with improved capabilities. Also, the original series can go to "Hypermode" which the later versions can't. Subverted by Shuko using a prototype that can barely move to beat the later version doll Wizard around like a, well, ragdoll even with vastly inferior tech and movements simply because she's that good.
* ''Manga/GetterRobo Āḥ'' has mass-produced Getters who are nowhere near the godly power of Shin, who was too terrifyingly destructive to replicate. There's also the fact that limiting the amount of Getter Rays the machines can hold prevents them from [[spoiler:turning sentient]]. In ''Getter Robo Armageddon'', Professor Saotome mass produces Getter Robo G in massive numbers with the sole purpose of forming them into Shin Dragon. Ryouma doesn't care and still beats the machines to a pulp.
* The [[EliteMooks Hyper-Zoanoids]] in ''Manga/{{Guyver}}'' are, like ordinary Zoanoids, genetically-altered humans. The "hyper" designation is usually applied to prototype genetic templates, which are designed around an individual soldier's DNA; mass-production designs must be simplified to allow them to work on a wider range of humans, so the Hyper models tend to be considerably more powerful.
* ''Anime/{{GaoGaiGar FINAL}}'' is a zig-zagging example that ultimately plays this straight. [=GaoGaiGar=] and [=GaoFightGar=] are both based on the blueprints of [[spoiler:Genesic [=GaoGaiGar=]]], but are significantly weaker; partially due to [[spoiler:humans]] being unable to perfectly copy [[spoiler:alien]] design, and partially on purpose, as some of the original's weapons were modified to serve non-offensive purpose. However, [[WordOfGod supplementary materials]] explain that [[spoiler:Genesic [=GaoGaiGar=]]] would have actually performed ''worse'' against the earlier foes, since it was designed to combat the Sol Masters, while the later [=GaoGaiGar=] and [=GaoFighGar=] were purpose-built for taking on Zonders and the 31 Primevals. For all intents and purposes, however, [[spoiler:Genesic [=GaoGaiGar=]]] is a straight upgrade when it's acquired, since [[spoiler:the destruction of the Z-Master, and [[NoOntologicalInertia with it all Zonder metal]],]] has rendered the later models' advantages moot.
* In ''LightNovel/InfiniteStratos'', it turns out that Ichika's [[PoweredArmor IS core]] is actually the very first one ever made. It's noted that the inventor "poured all [her] heart and soul into that core," since it was her first creation. Note that this is ''not'' the reason he can use the IS ([[GenderRestrictedAbility he's the only male who can]]); rather, that is [[spoiler:never revealed. Not even the original inventor understands why]].
** Houki's fourth-generation Aka Tsubaki might appear as an AceCustom but one cannot forget that it was personally built by the inventor mentioned above and is thus guaranteed to be superior to future fourth-gen designs (for reference, various companies around the world have only begun prototyping and performance testing of ''third''-gen IS units).
* In ''Anime/FutureGPXCyberFormula'', the Ogre AN-21 is the prototype to the Al-Zard NP-1. Ogre has the same bio-computer system as Al-Zard, but it also caused the deaths of 2 test drivers due to the fact the car was unable to satisfy the talent the bio-computer needed.
* The Sizzlers of ''Anime/GunBuster'' are mass-produced versions of the Gunbuster itself, smaller and weaker (yet powerful enough to fight dozens of alien bugs easily!)
* ''Anime/MartianSuccessorNadesico'' had a lot of fun with this. The original Aestivalis were already Super Prototypes when two more appeared, Akatsuki's special Aestivalis ([[AceCustom with new armor material and engine, befitting the CEO of Nergal]]) and the FlawedPrototype X-Aestivalis. By the time of the movie, they've mass produced the Aestivalis to remove its MechaExpansionPack and the need to be constantly recharged and they ''still'' build Super Prototypes of the Aestis, in this case the Aestivalis Customs and the Super Aestivalis.
* An interesting twist on this trope is utilized in ''Anime/GargantiaOnTheVerdurousPlanet''. The [[AMechByAnyOtherName Machine Caliber]], "Chamber", is just one of many of the Galactic Alliance's RealRobot troops fighting against the hostile alien force known as the Hideauze in outer space, and many are destroyed in the first battle during episode 1. However, on Earth, due to their much less advanced technology, Chamber is essentially a this trope. It is so advanced compared to the Earthling's mechs that they can't even make a dent in its hull, even with jackhammers.
* ''Anime/LegendOfGalacticHeroes'' has a decent number of them, on both sides:
** On the Imperial side, most dedicated flagships are unique vessels used to test new technologies that may or may not be employed on mass-produced ships, with the few that aren't being enlargements of more standard vessels or part of a couple of little-produced flagships;
** On the Alliance side we have the ''Triglav'' (a new flagship design, superior to the standard ''Ajax''-class and slated for mass production) and the ''Leda II'' (a new cruiser design with a curved armour design capable of [[NoSell deflect with little to no damage enemy weapon fire]], at least at distance. She too was slated for mass production).

[[folder:Comic Books]]
* This happens when any villain tries to replicate a SuperSerum. The first villain to try it is bigger, stronger & faster than the original, but the original never pushes it to the limits because of the [[IdiotBall idiocy-inducing effects of an overdose]], or the subject becoming completely musclebound or even ''[[LudicrousGibs exploding]]''. On the rare occasions that the villains continue to use the super serum on {{Mooks}}, they will have much smaller doses and usually be sent in groups.
* Related to the above, Comicbook/CaptainAmerica is the super prototype for the Super Soldier program. Others are constantly trying to replicate his success with results ranging from severe mental deterioration (Isaiah Bradley from ''Truth: Red, White and Black'', and William Burnside, the [[LegacyCharacter 50's Cap]]) to creating the Comicbook/IncredibleHulk (Comicbook/UltimateMarvel) and the Weapon Plus program (Comicbook/{{Wolverine}}, aka Weapon X/Ten; Steve Rogers is Weapon I). Captain America's shield is a Super Prototype as well, being the precursor to adamantium. Adamantium is the attempt to recreate the material of his shield, but even primary adamantium is weaker than it.
* There's also ComicBook/NormanOsborn being the super prototype for the Goblin Formula. It was meant to increase intelligence, but also added SuperStrength, insanity and a powerful HealingFactor. Most other Goblin Formula users tend ''not'' to get the Healing Factor and double down on the insanity portion.
* ComicBook/IronMan both subverts this trope and plays it straight. The subversion comes from Stark constantly producing improved models after the original prototype. The straight examples come from any even vaguely mass-produced derivatives, like the Guardsman armors, which are never on par with Iron Man's own gear. Of course, readers probably wouldn't want a bunch of glorified prison guards to be as powerful as the superhero. And, in fact, it's explained that Iron Man himself doesn't want a bunch of glorified prison guards to be as powerful as he is. He deliberately withholds the best tech for himself and even goes so far as to build in exploitable weaknesses in case the armors are ever used against him. Considering the number of times Stark's technology has been stolen, duplicated or reverse-engineered, he's got a right to be paranoid and hold back technology (although, as seen in the ''Armor Wars'' story, sometimes he takes that right too far, beating up innocent people like Stingray and Captain America).
* In a way, [[Comicbook/IncredibleHulk the Hulk]]. While created by accident, Hulk was the first gamma mutant, and most following gamma beings (the Leader, the Abomination, Madman, Ravage, etc) were based off either recreating that accident or specifically copying his DNA. While some have had greater base-line strength than the Hulk, and most have retained their higher intelligence whereas the Hulk is most often shown to be a savage, Hulk's potential strength (increasing with anger) and his other abilities (HealingFactor, psychic resistance) have shown him to be the most powerful of the gamma beings. Another factor in the Hulk's Super Prototype-ness is the fact that Bruce Banner's psyche is so damaged, because of abuse he suffered as a kid, that it allows him to do whatever he wishes. Becoming a gamma beast meant unleashing a particular repressed trait. The reason the Hulk is stronger than the others? Because they're not as screwed up as Banner!
* While the ''massive'' ContinuitySnarl in ComicBook/XMen makes saying this definitively difficult, there's a fairly good chance [[KnightTemplar Exodus]] was this for X-Men BigBad ComicBook/{{Apocalypse}}. Empowered by Apoc in the 12th century, Crusader knight Bennet du Paris rebelled against his would-be master and was [[Really700YearsOld sealed away for over 800 years]] as a result. When ComicBook/{{Magneto}} woke him up in the present day and recruited him to his Acolytes, Exodus proved capable of throwing down with the entirety of the Avengers and X-Men teams ''simultaneously'' while ''[[UpToEleven also]]'' crushing the entirety of an island nation's capital city beneath the power of his telekinesis. Not a single one of Apocalypse's other later minions, from [[EvilutionaryBiologist Mr. Sinister]] to the [[FourIsDeath Four Horsemen]], have exhibited anything near this kind of power.
* The ComicBook/{{Blackhawk}}s' aircraft during UsefulNotes/WorldWarII was the [[http://en.wikipedia.org/wiki/XF5F_Skyrocket Grumman XF5F Skyrocket]], an aircraft that never made it past the prototype stage in RealLife.
* Comicbook/SuperDinosaur is superior to the successive Dino Men because of his armor which grants him unparalleled firepower.
* In ''ComicBook/ArchieComicsSonicTheHedgehog'', the Metal Sonic Troopers -- which both Rotor and Uncle Chuck designed and built, based upon the original Metal Sonic -- are easily dispatched when they're turned against everyone, compared to the original Metal Sonic, who gave Sonic and co. a very hard time. And then there's all those replacement Metal Sonics Eggman keeps making, which always get rolled out and blown up within five pages. They've practically become a running gag.
* In the ''ComicBook/AstroCity'' story "Pastoral", Roustabout escaped the experimenters who made him superhuman and killed the rest of their subjects. Team Carnivore, their apparent next attempt, came to track him down because they were not so successful, and their bosses hope to take him apart and learn the trick.
* ''ComicBook/TheBoys'' goes at this from every angle. Though it's not commonly known, every superhuman in the series is the result of "Compound V", a SuperSerum created by Dr. Jonah Vogelbaum, a German scientist who fled the Nazi regime with his SuperPrototype [[StupidJetpackHitler former Hitler Youth member Stormfront]]; a FlyingBrick stronger than the vast majority of characters. However, Stormfront is nowhere near as powerful as his {{Ace Custom}}s The Seven in general and his MagnumOpus Homelander in particular - and ''all'' of them cost truly ridiculous amounts of money. The protagonists got their enhanced strength and resilience from a Compound V knockoff that cost ''nineteen billion dollars per shot''. When Vogelbaum died, the MegaCorp that licensed them just plain stopped production, switching to recruiting "naturally occurring" superhumans -- that actually got their powers from the their constant experiments with the serum having contaminated the environment, causing random mutations that never really stack up to the AceCustom nature of the original generation. Also, [[spoiler:Vogelbaum didn't really die, but was recruited by the government to make The Boys' serum]].

[[folder:Fan Works]]
* In ''FanFic/{{Exoria}}'', a modern-day ''Zelda'' FanFic, Epona is a [[CoolBike prototype military motorcycle]], codenamed MRX-402A (second prototype model of the fourth generation military reconnaissance X-series). Aside from being able to achieve speeds over three hundred kilometers per hour, it has onboard electronic systems that allow it to analyze the terrain ahead instantly and adjust the suspensions real-time. It also has an auto-drive function, and two .50 machine guns. Seatbelt not included.
* ''Manga/{{Evangelion 303}}'': The F-14E "Evangelions" (which in this alternate universe are experimental jet fighters rather giant robots). The first models are more powerful and have a better output than the latter ones. There also were talks to mass-produce them, but the Committee overseeing the project decided that it would be too expensive and the prototypes are good enough.
* ''Fanfic/{{HERZ}}'': Unit 00, 01 and 02 were the prototype, test type and production models respectively. However 01 was the most powerful of the trio. The MP-Evas were the mass production model, meant to be more advanced (they flew, had unlimited power, quick regeneration and were armed with replicas of the Lance of Longinus). Still Asuka piloting Unit 02 tore them apart nearly completely, and Shinji riding Unit 01 finished them off. In 2027 [[spoiler:SEELE built even more powerful mass production Evas, but the three pilots easily defeated them using their old models.]]
* Subverted and defied in ''FanFic/AnEntryWithABang[=!=]'': The first GDI monitor is an unstable hodgepodge of Clancy-Earth and ''TabletopGame/BattleTech''... uh, tech. The first prototype [=BearCat=] aerospace fighter is not mounting weapons. Both in-universe and at the writers' level, there has generally been agreement to take things slow and not do any funky stuff.
* In ''FanFic/ProjectIgnition'', there's the [=TYPE-Sione=] new model NEXT, which is obscenely powerful...[[spoiler: [[SubvertedTrope The three stolen TYPE-Siones are actually production models, not prototypes. The Prototype is actually the exact same machine given to an unknown pilot. However, the Union stealing the TYPE-Sione is enough to start the Interior-Omer war.]]]] Also there's the [=XAF-Kushina=], a prototype Arms Fort that actually is serving as Omer Science Technology's Main AF [[spoiler: The Kushina is merely a prototype attempt at creating an XG-70 with Kojima Technology-- it doesn't perform to Omer's standards, despite being able to lay waste to an entire continent.]], lastly there's the Fudai, a Light-weight NEXT being developed by Arisawa, following a recommendation from Tadashiro- subverted in that the ''Zephyr Fudai'' is merely a [=TYPE-Lahire=] with proof of concept parts, and is quite inferior to what Tadashiro has in mind for the actual Fudai. [[spoiler: It matches one on one with Adler's Zephiris, and Tadashiro has never piloted a NEXT before that point.]]
* C.L. Werner's ''[[FanficRecs/{{Godzilla}} New Era]]'' ''Franchise/{{Godzilla}}'' stories were set to feature the [[Franchise/{{Gamera}} Ultra-Gyaos]], progenitor of the entire Gyaos race. It was a creation of ancient Atlantis meant to be used to destroy Mu, but when they saw it was powerful enough to betray and destroy them, the Atlanteans were rightly frightened and [[SealedEvilInACan sealed it away in an orihalcyon chamber deep beneath their kingdom]]
* In ''Fanfic/FalloutEquestriaEmptyQuiver'', we have the XB/A-1 Valkyrie, an experimental delta-wing supersonic attack bomber capable of effectively flying indefinitely, vertical takeoff and landing, and carrying 5 tons of bombs meanwhile, with no less than four turreted tesla cannons for defense and two 40mm autocannons for offense. It was still in the process of being tested when the bombs fell, preventing its use and ultimately its mass production, making it the only one of it's kind.
* In ''FanFic/SonicXDarkChaos'', Tsali himself was this to the Tsali Endoskeletons. It's later revealed to be a JustifiedTrope - the endoskeletons were built in the last days of the Demon-Seedrian War, with the Seedrians nearly wiped out and scraping together anything to slow the Demons down.
* Played with in Fanfic/{{Marionettes}}. [[spoiler:Trixie is the first Marionette, both as a whole and of the current Generation (her AI and the MagicWand composing her horn having been transferred into a new body), and built to rival Sunet and Twilight in strength while Cover Story (another Marionette) is easily overpowered by the latter.]] However, the reason for this [[spoiler:is because she was built to be TheRival to Sunset, and thus power was necessary, particularly since it was believed that Sunset and Twilight could become Alicorns.]] Another reason is [[spoiler:the MagicWand in her horn is one of two like it in existence, being one of Mage Meadowbrook's Enchanted Objects, and thus couldn't be replicated. Also Subverted overall, as generally the more advanced Marionettes ''are'' superior to the previous generations, including Trixie's new body to her original.]]
* In ''Fanfic/EquestriaAcrossTheMultiverse'': All the PoweredArmor suits have this for justified reasons. The prototype model (the 'Advanced' Model) for both the Paladin and [=RANGER=] Armors are far stronger than the mass production model, but are also impossible for a normal pony to use. The Advanced Model Paladin Armor's mana requirements are too high for anypony who's not exceptionally powerful (Shining Armor, Gifted Ponies, ect.) or has some magical artifact or ability (the Bearers, Alicorns, ect.) to actually sustain them for extended periods, thus the mass production versions, while much weaker, can be used by anyone while the Advanced versions are reserved for those who can actually use them. The [=RANGER=] armor's prototype turned out to be far too strenuous for a normal pony to use and Sincere Heart (Shining Armor's Tales universe AlternateSelf) is the only pony available who can properly use it, while the mass production model is usable by anyone. The only suit ''not'' the have this trope attached is the Bard Armor, but that's because it runs on Innocence Magic, and only certain ponies can use that anyway.

[[folder:Films -- Live-Action]]
* In ''Franchise/StarWars'', Darth Vader's TIE fighter was a custom model with a distinct appearance. At least one ExpandedUniverse technical manual says it's one of a Low-Rate Initial Production batch of unsuccessful Super Prototypes; the design was rejected as too expensive and the TIE Interceptor was selected instead.
** This was further explained in the Expanded Universe, specifically the ''VideoGame/TIEFighter'' game. They had designed a different model similar to Vader's TIE Advanced X1 that was intended for mass production, known as the [[http://starwars.wikia.com/wiki/TIE_Avenger TIE Avenger,]] but it and its successor, the [[http://starwars.wikia.com/wiki/TIE/D_Defender TIE Defender,]] were shelved due to too many resources expended during internal civil war. Which was probably a good thing for the Rebels, seeing as how the Defender was widely considered to be the most advanced starfighter of its time.
** The Trade Federation in ''Film/ThePhantomMenace'' uses two types of battle droids, that look the exact same. You have the OOM models, which possess advanced and independent programming, and the B1 models, which are [[TooDumbToLive dumb as a box of rocks]]. The kicker, the [=OOMs=] are the prototypes. You would think that with code being easily replicated, ALL battle droids would be [=OOMs=], but instead the Trade Federation decided to shoot themselves in the foot. Expanded Universe sources indicate that they feared an droid army in which every soldier was capable of intelligent thought [[RobotWar might turn against them]].
* Batman's costume in ''Film/BatmanBegins'' is a prototype armor suit that was rejected by the army because it was too expensive. The same with the batmobile, which was designed for jumping gaps to lay cables for bridges.
* Franchise/MarvelCinematicUniverse:
** Steve's nearly-indestructible shield in ''Film/CaptainAmericaTheFirstAvenger''. When he asks why it isn't standard issue for normal soldiers, Howard Stark says it's because the metal used to make it is too rare to produce more copies.
** Comicbook/TheFalcon's flying exo-suit in ''Film/CaptainAmericaTheWinterSoldier'' is a military prototype. No reason is given for why the suits never saw mass production, but it's implied that the other users had all been killed during combat in the Middle East. It was also designed for Para-Rescue. Among the U.S.'s special forces units, Para-Rescue is among the most difficult to succeed in, on par with Seal Team 6, if not outright more difficult. Training is often nicknamed "Superhero School". Given that it would naturally have a low radar profile, it was probably meant to be a poor man's Iron Man but was too costly, too narrow in mission, and had little-to-no body armor to protect the much more valuable man wearing it.
* The ''Franchise/RoboCop'' program arguably nailed the concept in their first try, but failed to deliver a single functional/reliable cyborg after that. In ''Film/RoboCop2'', a string of subsequent models failed in increasingly gruesome ways - it turns out there are certain qualities the person must possess for the operation to work properly. Knowing this, the corporation [[TooDumbToLive resorted to a junkie drug lord]] with [[DarkMessiah a messiah complex]] as source material, reasoning that his addiction and vanity would help keep him in line (ItMakesSenseInContext). The results were quite unsavory, to say the least.
* In ''Film/TheLastStarfighter'', Alex's Gunstar is stated to be an advanced prototype for the next model of Gunstars, featuring improvements in weapons, armor, and other experimental systems such as the [[BeamSpam Death]] [[MacrossMissileMassacre Blossom]]. Because it's still a work-in-progress, it's kept in a separate area of the base from the main hanger, [[spoiler:which is why it's the only Gunstar not destroyed in Xur's sneak attack which destroyed most of the Starfighters' base. Since it's the only Gunstar they've got left, they have no choice but to use it despite it being largely untested.]]
* ''Film/{{Firefox}}'' has two of the titular planes, and centers on [[GrandTheftPrototype the theft of one of them]].
* ''Film/InspectorGadget'' and his EvilTwin [=RoboGadget=] are these. Gadget himself doesn't become a FlawedPrototype until the sequel.

* In Joel Shepherd's Cassandra Kresnov trilogy, the title character is a prototype of a new and improved version of the [[RidiculouslyHumanRobots "GIs"]] used as soldiers in interstellar combat. The main improvement is in her intelligence rather than her physical capabilities. She is creative and capable of lateral thought, making her more flexible and independent than lower level [=GIs=] who mostly serve as grunts that follow orders.
* In the ''Franchise/StarTrek'' novel ''Final Frontier'' (no relation to the fifth movie), it was revealed that the ''Enterprise'' was the prototype for the ''Constitution''-class line. It was deliberately overbuilt, explaining how Kirk (and Scotty) could constantly push it past its design limits. Constitution ships-of-the-line were economized, resulting in them being more delicate ships.
* In ''Literature/MadSkills'' by Walter Greatshell, coma patient Madeleine Grant is a testbed for an experimental brain surgery that uses leech brain cells to supercharge her mind to Singularity levels. [[spoiler:Actually, she's a prototype testbed for a ''lot'' of separate projects, qualifying as an ArtificialHuman to some degree; [[TomatoInTheMirror her body is the repurposed shell of a brain-dead pop star]], while her brain is entirely artificial and contains [[FakeMemories heavily-edited memories]] [[BrainUploading taken from an orphan girl who was quietly killed]], and ''that'' brain is what's upgraded with the Leech-Tron. The Leech-Tron also incorporates a wi-fi connection that allows subliminal commands and advertisements to be beamed directly into her brain, but the amount of brainpower she has available allows her to [[PhlebotinumRebel slip the leash]] by mid-book.]]
* In ''Literature/{{Daemon}}'', the first [=AutoM8=] is an armored, solid-tired Hummer that is ImmuneToBullets. Later versions use normal cars as a base and are thus less survivable.
* Mack Maloney's ''Literature/{{Wingman}}'' series makes liberal use of this trope, particularly in the case of Hawk Hunter, the titular Wingman. His main aircraft is arguably ''both'' a super prototype ''and'' an AceCustom, as he usually flies an F-16XL[[note]]only 2 were ever built[[/note]] which he has further modified with MoreDakka and advanced avionics. When circumstances force the Wingman to use a different type of aircraft for more than a chapter, he will generally take the time to similarly customize his new plane, often even transplanting the avionics from his F-16 into the aircraft.
* JustifiedTrope in ''Discworld/RaisingSteam''. Dick Simnel, the inventor of the steam engine on the Literature/{{Discworld}}, feels very proud of his prototype, Iron Girder. So every time he has a new idea for improving the engines it gets added to Iron Girder before the others, for testing purposes and because Dick can't stand the thought of her not being the best engine on the railway.
* In ''Literature/{{Paranoia}}'', the optical chip-- a new technology that would revolutionize the entire technology industry-- is the MacGuffin for the majority of the book. [[spoiler: It doesn't exist, and was a bluff created by Goddard to get Wyatt to bankrupt his company by buying a company that had the hold on making the process, thereby allowing Goddard to buy out Wyatt's company once it ran out of capital and his debts were called in.]]
* In ''Literature/TheStrangeCaseOfDrJekyllAndMrHyde'', the potion responsible for separating Jekyll and Hyde only worked because of an unspecified impurity in one of the ingredients. When Jekyll/Hyde ran out of the one contaminated batch, it didn't work anymore.
* The setting of ''Literature/{{Noob}}'' has the Empire's elite troops consist of an extreme case of MagicallyIneptFighter called neomancers: a special injection cuts them off from the world's magic system in exchange of what amounts to BioAugmentation. It's known from the start that the ijection contains genetic material from various beings that one could expect to find in a fantasy AdventureFriendlyWorld. The third novel reveals that mix is technically cells from Tabris, an entirely artificial super-being that was so powerful that the world's {{Physical God}}s considered it a treat and requested his destruction in exchange of a very big favor. The neomancers are individually extremely weak by comparison to Tabris.
* In ''Literature/LegendsOfDune'', Norma Cenva becomes the first Navigator. Unlike all subsequent Navigators, Norma has much more considerable PsychicPowers and is even capable of folding space on her own, without the use of a Holtzman engine. However, this is because of her Sorceress of Rossak genes, which none of the other Navigators possess.

[[folder:Live-Action TV]]
* ''Series/BuffyTheVampireSlayer'': Compare how good Adam's performance is to Forrest's -- though he purposely made Forrest "nearly as bad" as him.
* The CoolStarship equivalent is the USS ''Defiant'' in ''Series/StarTrekDeepSpaceNine''. In its debut, it took a dozen Jem'hadar attack ships (just ''three'' of which had shown themselves capable of easily destroying the previous most powerful ship in Starfleet) to disable the ''Defiant'', and that was after it was heavily damaged in an ambush. Not to mention, they hadn't even worked all the bugs out of the design yet; in later appearances it was even more formidable. The specs indicated that it was about 1/10 the mass of the ''Enterprise''-D yet carried armament equal to it. Starfleet eventually does make others which are apparently just as powerful ([[spoiler:including a replacement for the original when the Dominion finally manages to destroy it]]), but it takes a while to get them into production.
** Franchise/StarTrek actually kept a pretty good eye on its tech level as various ships are introduced. The registry for the prototype ships usually have an NX prefix. The ''Excelsior'' was originally NX-2000 and was more of a testbed for the (ultimately failed) "Transwarp" engine more than anything else. Once the testing phase was over, she was given a proper NCC prefix. Otherwise, it didn't appear to completely outclass other starships like the ''Enterprise'' in terms of combat performance. In later series, it seemed that the ''Excelsior'' design was actually one of the most versatile in terms of longevity, the design showed up as modern starships as late as ''[[Series/StarTrekDeepSpaceNine Deep Space Nine]]'''s fourth season, more than 80 years after it was introduced.
*** The titular ship of ''Series/StarTrekEnterprise'', the NX-01 ''Enterprise'', also subverted the super prototype as her successor, the NX-02 ''Columbia'', left drydock with capabilities that surpassed and were later retrofitted into ''Enterprise''. Production designs for the [[WhatCouldHaveBeen unproduced fifth season]] of ''Enterprise'' and WordOfGod statements from Doug Drexler recently revealed that the entire NX class was one big work-in-progress and that every ship was its own prototype, as evidenced by [[http://drexfiles.wordpress.com/2010/04/25/nx-01-refit-diagram/ these sketches]] showing off the engineering hull that was to be added to the "NX-01.5".
* ''Series/KnightRider'': In "Trust Doesn't Rust", KARR takes KITT for an "inferior production-line model" and assumes himself to be a super prototype. He turns out not to have any apparent technological advantage over KITT (of course, KITT is hardly "production-line"), aside from a slightly improved speech module (in the next episode, KITT's is replaced by one similar to KARR's), though when KARR reappears in the third season, while still not more advanced than KITT, he does possess a number of features which KITT had only gained during the second season.
** In the 2008 series, KARR is a TransformingMecha, specifically designed for front-line combat. However, it was a failure, and a number of people died. KITT was designed as a car that could transform into other cars (e.g. a Mustang transforming into a pickup truck) and mainly designed for policing duties. However, the episode where KITT is shut down reveals that the military has always planned for KITT to be a temporary project. The goal was to have KITT develop as a fully-functional AI and then port that AI into KARR. The kicker? [[spoiler:Both KARR and KITT have the same driver, the son of the original Michael Knight]].
* ''Franchise/SuperSentai'':
** ''Series/DenjiSentaiMegaranger'': The Megasilver suit is a lot stronger than the others... until we find out that its power only lasts two and a half minutes. (In ''Series/PowerRangersInSpace,'' the 2.5 minute problem existed for different reasons and the suit wasn't a prototype.)
** ''Series/ZyudenSentaiKyoryuger'': Tobaspino, the first Zyudenryu (number ''00''), demonstrates this each time it appears. Its first appearance was as a foe that could take on all of the other mecha on its own.
*** In a later appearance where the five Zyuden Giants have to split up to take on five clones of a monster in five different parts of the world, Tobaspino's [[TransformingMecha Zyuden Giant form, Spinodai-Oh]], takes out its opponent in mere minutes while the others (even the powerful [[EleventhHourRanger Bragigas]]) are stuck fighting for hours.
*** ''Series/BakuryuuSentaiAbaranger'' has Abare Killer, whose powers are stronger than any of the others but comes with a ''slight drawback:'' Unlike the later Dino Braces, Abare Killer's Dino Minder will eventually explode with enough force to leave a smoldering crater where the city used to be.
* ''Franchise/PowerRangers'':
** ''Series/PowerRangersRPM'' has the Paleozords, abandoned mecha from the early days of Project Ranger. The reason they were abandoned is because the zord tech hinges on bio-energy fields of living beings, and the Paleozords (based on dinosaurs, as you might have guessed from the name) were trying to connect to creatures that no longer existed, which made them powerful but uncontrollable. By the time the Rangers rediscovered them, the technology had advanced enough to bring them under control. Another example are with the morphers. The morphers used by Gem and Gemma are prototypes and thus do not carry the same energy limitations that the later versions used by the rest of the team. However, they also don't have the Burst Attacks.
** In ''Series/PowerRangersTimeForce,'' the Quantum Ranger morpher and Quantasaurus Rex Zord were created during the early days of Time Force, and lost in an early time travel experiment until being rediscovered. However, they're quite stronger than the main five Rangers and any of their tech. However, there's a drawback: the main five have a DNA lock, so only you or your IdenticalGrandson can use it (hence Wes). The Quantum powers have a ''voice'' lock, making it easier for, say, the MonsterOfTheWeek to sic your Zord on the Rangers with just a voice imitation device.
* ''Franchise/KamenRider'':
** ''Series/KamenRiderAgito'': The Kamen Rider G3/G3-X armor boils down to being this, especially after the introduction (and later mothballing) of the Kamen Rider G3 Mild armor.
** ''Series/KamenRiderFaiz'': The mass-produced Riot Trooper gears are nowhere near as good as the unique Faiz gear (the fact that the Faiz gear has two alternate forms and a bike that can transform into backup in a pinch not withstanding).
** ''Series/KamenRiderDouble'': Kamen Rider Skull is the single-user prototype for Double, but is just as good in combat, best illustrated by its being a jack-of-all-trades combination of Shotaro's Memories (melee brawler like Joker, good defense like Metal, TheGunslinger like Trigger).
** ''Series/KamenRiderOOO'': Averted with Kamen Rider Proto-Birth, as the prototype Birth Driver has only a few of the functions of the later model, and is used as a backup when the main driver is damaged. [[spoiler: Then [[TheBusCameBack Date returns]], and takes the prototype in order to back up Goto.]]
** ''Series/KamenRiderWizard'' has Kamen Rider Beast, who uses an ancient belt while Wizard uses a modern one. Despite this, Beast's default form is as strong as Wizard's MidSeasonUpgrade form. Possibly subverted, as the White Wizard later implies that Wizard is overly ''weak'' for a spellcaster and what counts for him as a MidSeasonUpgrade is where everyone else naturally starts at.
** ''Series/KamenRiderGaim'' has the Yomotsuheguri and Forbidden Ringo lockseeds, which were both created at an early stage of research of the Helheim forest. They are vastly more powerful than most other lockseeds, but using them kills the user. Both serve as GodzillaThreshold of sort at some point of time.
** ''Series/KamenRiderDrive'': The prototype for the Roidmudes is number 000, aka Proto-Zero or more commonly, [[spoiler:Chase]]. He's one of the strongest fighters in the series, and both the Roidmudes and the Kamen Riders seek to have him fight alongside them.
** ''Series/KamenRiderExAid'': The prototype gashats are more powerful than the regular ones if used correctly, but have unfortunate side effects. What exactly it's supposed to mean is not specified besides them being said to 'ruin the user's body'. The best indication given is when a normal person uses a Gashat? They get the Bugster Virus. When a normal person uses a ''prototype'' Gashat? They violently ''vomit up blood near instantly''.
* The eponymous "super-sub" in Creator/GerryAnderson's series ''Series/{{Stingray 1964}}''. All the other W.A.S.P. ships that we see are more-or-less conventional-looking (for the 1960s) submarines, and there is no indication that there is more than one of the class. ExpandedUniverse material in the ''TV Century 21'' comic and official novels imply either that a second ''Stingray''-class sub has been built (and enters service just in time to be stolen by the Mysterons) or that ''Stingray'' is an ungraded version of a standard W.A.S.P. patrol vessel with superior capabilities to its sister craft.
* The robot Imperiser/[[SpellMyNameWithAnS Imperialiser]] from ''Series/UltramanMebius'' is insanely hard to destroy with thick armor capable of self-regeneration and can evolve ''right in the middle of battle''. The mass production version lacking said qualities, they are still deadly nonetheless. And since they retain teleportation ability, [[WeHaveReserves their strength in numbers does made up with it]].
* The ''Series/{{Battlestar Galactica|2003}}'' prequel ''Series/{{Caprica}}'' features a super prototype, the first U87 Cylon equipped with a metacognitive processor displays the potential for near human autonomy. The problem with this is this level of intelligence is only achieved in a single prototype, if the MCP is placed in a different cylon it does not display sentience.
** The Original ''Series/{{Battlestar Galactica|1978}}'' series had the C.O.R.A. Viper. Very fast, full A.I. computer piloting system, equipped for long range patrols, double the thrusting power of any other Viper -- at the expense of the guns!
* On ''Series/{{Chuck}}'', Chuck is the first successful Intersect and remains the only prototype due to repeated sabotage of the project. However, when they finally decide to create more Intersect agents, they turn out to be way too inflexible in their thinking and tend to overreact in combat situations. In this case, it's a matter of NoPlansNoPrototypeNoBackup for both device ''and'' user: nobody can reproduce the perfect version of the Intersect that Bryce Larkin only entrusted to Chuck, and when it comes to the wielder, well, there's a reason Bryce only trusted Chuck with it. With later attempts to produce it, you got fatal MySkullRunnethOver cases, madness-inducing cases, and a version that damages your memory with each use to the point that it was once used as a form of BrainWashing. The only non-Chuck person who appears to have had a fully functional Intersect was a BigBad.
* [[CelestialParagonsAndArchangels Archangels]] in ''Series/{{Supernatural}}'' were the first four angels created and much more powerful than their younger siblings. [[spoiler: God eventually reveals this is because the Archangels were created using primordial power that takes a long time for him to make, meaning it takes him a lot longer to make an Archangel than the normal angels. This was problematic when the second fight with the Darkness happened, as by then, Lucifer was the only Archangel in fighting shape and resurrecting Raphael or Gabriel or making a new Archangel would've taken more time than they had]].

* It's fairly common for the prototype versions of {{Pinball}} machines to have features that get stripped out for the actual production run, usually for cost or technical reasons. Enthusiasts today sometimes produce kits to restore the lost features. Some notable examples include:
** The "Boogie Man" slingshots on ''Pinball/ScaredStiff''. The rubber figures on the slingshot bumpers were supposed to jolt each time the kicker fired, but it was found this would eventually cause the Boogie Men's arms to fly off, so they became fixed in place on the production versions; replacement kicker arms are available that make them mobile again.
** The chime bars in ''Pinball/TheWhosTommy''. The theme was meant to evoke early electromechanical pinball machines which used metal chimes to produce their sounds. The prototypes had three chime bars, but these were removed in the production cabinets and electronic sounds were substituted. Some owners have retrofitted chime units from other games.
** The Deadworld area in ''Pinball/JudgeDredd'' was supposed to lock balls for multiball, but it was found to be unreliable. Custom kits exist to restore that feature.

* Apocryphally, Lilith. The first woman created by God, made of dust (like Adam) instead of being made from part of Adam. She wanted to be treated as Adam's equal but her strong will caused a bunch of relationship troubles, so they got divorced and God settled for a more passive production-model woman in Eve who would be more supportive (and/or more subservient) to Adam. She's also something of a FlawedPrototype, given that she, while still angry over her would-be marital issues, declared she would kill newborns if they didn't have amulets with the names of certain angels transcribed on them as part of a deal to get them to leave her alone. In a sense, that makes her a cause of sudden infant death syndrome.

[[folder:Tabletop Games]]
* Largely averted in ''TabletopGame/BattleTech''; while it is true that during the still-popular late Succession Wars era such older "lostech" designs as still existed in half-decent shape could be superior to anything of more modern manufacture, those were generally leftover ancient ''production'' models. Actual prototypes and first-generation designs using newly recovered or developed technologies tend to play [[FlawedPrototype another trope]] rather more straight (one very common fandom term for this is "new toy syndrome").
** There ''were'' a number of prototypes in the Jihad era that are incredibly effective, and mount a number of high end "experimental" technologies that usually only show up on or two at a time on production models. When production versions of the designs were printed, they largely tended to be less powerful due to having reduced advanced/experimental tech on them for the reason that either it was decided that it wasn't necessary for their intended roles so reducing the advanced tech on them made them cheaper, or the specific bit of tech was considered too difficult to keep working in the field and so [[BoringButPractical older and more reliable equipment]] was used instead.
* Since they're one of the only factions in ''TabletopGame/{{Warhammer 40000}}'' whose technology is actually ''improving'', the Tau exhibit this trope when it comes to their [[PoweredArmor battlesuits]]. Ace battlesuit jockeys are given the chance to field-test advanced prototypes, and if a Tau commander does ''really'' well they may end up with their own AceCustom suit. Unfortunately these shiny new features tend to come with a drawback or two, something notably absent in normal Tau technology.
** This kinda applies to any sort of technology used by the Humans (of any faction). The most powerful weapons are inevitably some super-ancient prototype relic. Kind of hand-waved due to a.) the Adeptus Mechanicus's fear of inventing, b.) the relics themselves being of Alien origin and/or a sacred relic and c.) sometimes the owners flat out refuse to let anyone tinker around with their one-of-a-kind toy.
*** The Thunder Warriors are specifically stated to be cruder, more poorly armored versions of the process that creates modern SpaceMarines, but at the same time, a single Thunder Warrior is to a squad of marines what marines themselves are to a squad of [[RedshirtArmy regular guardsmen]]. Unfortunately they are nowhere near as stable, mentally or physically. [[spoiler: The Emperor had them all (mostly) wiped out after conquering Earth in favor of the more reliable Space Marines.]]
*** The Adeptus Custodes ''may'' qualify, as superior warriors rumored to be forged from the Emperor's gene-code, rather than a Primarch's. It's not clear whether the Custodes or the Space Marines came first. Unfortunately, as the comatose Emperor's PraetorianGuard, [[TheyWastedAPerfectlyGoodPlot they have been essentially confined to the role of the guarding the Imperial Palace since the Heresy.]]
** Played straight with the Primarchs, who are superior to any other soldier the Imperium has and are the templates for almost all of the Space Marines in existence today. However, the process which created them was extremely intensive and [[UnreliableNarrator may or may not have involved stealing power from Hell to achieve]] and the Emperor only managed to create 20 of them, which he later deemed to be used as the templates for the Space Marine Legions and commanders for said legions. They were, however, basically DesignerBabies (from the Emperor's DNA himself) where Space Marines are people born normally with genetic engineering applied later.
** Much of the space marine legion's equipment are this to "modern day" 40k; the Cataphractii Terminator armor, Imperial Jetbikes, Hover Rhinos, Fellblade super-heavy tanks and the iconic Contemptor Dreadnoughts were all miles above their contemporaries in their roles and were once slated for mass production, but due to the onset of the Horus Heresy (where the majority of these went to the traitor legions and subsequently were destroyed) and the Imperium being gripped by superstition, they would never see it. After a few millennia, the method to make these were lost, and any existing suits were revered as relics, used only by the most hallowed member of their chapter or anyone already in possession of one.
* ''TabletopGame/JovianChronicles'', Dream Pod 9's Franchise/{{Gundam}} inspired setting, is naturally filled with them. A couple of the prototypes do get mass produced versions, but they pale in comparison to their predecessors.
* ''TabletopGame/MagicTheGathering'' manages to avert it in one respect; the [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=49046 Myr Prototype]] is way overpriced for what it actually does.
** This trope is prevalent in ''Magic'' on a more "meta" level: The designers are constantly trying to make more balanced versions of older, overpowered cards. [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=3 Black Lotus]], the original [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=36 Moxen]], and the original [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=287 dual lands]] are among the game's many Super Prototypes. (The flip side is also present, as the power level of creatures has in many ways been [[PowerCreepPowerSeep steadily increasing]], including creatures that are strictly better versions of older ones, making those early Magic creatures seem like [[FlawedPrototype flawed prototypes]].
* ''TabletopGame/{{Shadowrun}}'' introduced a trio of uber-powerful, almost godlike AIs. Once the Crash 2.0 hit and the three of them are (apparently) gone, AIs are now roughly as powerful as human hackers in the Matrix (to the point where they are options for player characters).
* Appears in ''TabletopGame/HeavyGear'', specifically as the background to the South's Gold Mamba design. The Gold Mamba was basically a prototype built at the same time as the common Black Mamba, but contrary to typical design theory (build something up until it works at the level you want), its designers approached it from the other side of the spectrum (put the most expensive equipment you can find on it and scale down until it doesn't work). This means that the Gold Mamba is an extremely powerful combat machine that is head and shoulders above the Black Mamba's performance, but ultimately it is extremely expensive and rare.
* The proxies of ''TabletopGame/{{Trinity}}'' were the first humans to become psions, and their psychic powers are noted to be significantly more powerful than later psions, as the process that created the proxies differed in important respects from the one used for other psions.
* The Saga Edition of ''TabletopGame/StarWarsD20'' features a ship template called Advanced Prototype, which improved most of the stats of a base ship -- but because it is a fine-tuned machine (again, more of a concept than an actual prototype), you would have to perform maintenance more regularly.

* From ''Toys/{{Bionicle}}''
** [[BigBad Makuta]] [[MadScientist Teridax]] seemed to have a habit of creating prototypes that were much stronger than the mass-produced versions that'd come later, though in his case that was usually because his creations [[AmbitionIsEvil tended to be too intelligent or ambitious to serve his goals]], so he'd scale them back in power and intelligence to ensure they wouldn't become a threat. Also, he made them with [[YourDaysAreNumbered limited lifespans]] to ensure they wouldn't remain a thorn in his side for too long even if he didn't bother with killing them.
** One of Makuta's creations, the [[FantasticFlora Karzahni]], was this to its successor, the Morbuzakh. It had all the Morbuzakh's abilities (incredible strength, complete control of its vegetation, capable of intelligent thought and speaking), plus it lacked the need to feed off of fire and heat (since it survived just fine in the sun-less darkness of the tunnels between Metru Nui and Mata Nui) and possessed immunity to ice and cold (casually shattering a layer of ice over its form that would have crippled its successor for a time). However, it was far too ambitious and intelligent to be content with Makuta's plans for it and rebelled, so he banished it and made the Morbuzakh with the mentioned flaws (plus being less intelligent) so it would serve him alone. The Karzahni [[{{Revenge}} did not like that in the slightest and started planning Teridax's downfall and death]].

[[folder:Video Games]]
* Proto Man of the ''VideoGame/MegaManClassic'' series is usually depicted as being much more capable than the later model, Mega Man, and due to a bug in his design, a flawed nuclear core, is the first robot in history to have full free will. On the flip-side, that same unstable core makes him far more vulnerable to damage and means his power reactor will catastrophically fail at some point (Implied to be ''quite soon'' in ''VideoGame/MegaMan10''). On the plus side, being built with an energy source far more raw and unrestrained generally makes his buster output more powerful than his brother ''or'' Bass, enabling the extremely potent Proto/Blues Strike.
** VideoGame/MegaManX is himself a Super Prototype to all of the Reploids that were created afterwards. He was built with the ability to make his own decisions like Proto Man above, but was built with a "suffering circuit" that would allow him to weigh the consequences of his actions. This, plus over a century of self-checks made X a perfect machine. The Reploids that were built from his blueprints, however, lacked the same power of his suffering circuit and the checks, which caused many of them to become [[KillerRobot Mavericks]]. In general, the whole of the Mega Man franchise typically provides some viable explanation as to why a first draft might be superior to the later models.
* The OriginalGeneration mecha of ''VideoGame/SuperRobotWars'' is ''overloaded'' with super prototypes, {{Ace Custom}}s,and a few {{Flawed Prototype}}s too; way, ''way'' too many to list on this page. Averted in ''VideoGame/SuperRobotWars3''. When you begin the game, the Manga/GetterRobo team is piloting the Proto-Getter Robo. instead of normal Getter Robo. When Proto-Getter attacks and doesn't kill an enemy, Ryouma gripes that the Proto-Getter is just weaker than the normal Getter and is actually happy when the original Getter is dropped in a few stages later.
* In the ''VideoGame/MetalGear'' series, the prototype Metal Gear RAY is of far superior quality to the mass-produced models later encountered by Raiden as a boss battle; then again, it may have been actually designed for its supposed purpose (to defeat REX derivatives) whereas the mass-produced versions were actually tactical defense units for Arsenal Gear. In ''VideoGame/MetalGearRisingRevengeance'' Bladewolf, a prototype unmanned gear, is self-aware and pretty durable, while the mass-produced Fenrirs go down much faster and have less intelligence than a real dog.
* The original X-Blade from ''Franchise/KingdomHearts'' was practically this to the keyblade. It originally coexisted with the true Kingdom Hearts, acting as its guardian. However, numerous people used the X-Blade as the basis for their own keyblades, leading up to the inevitable Keyblade War for control over Kingdom Hearts, which sunk the world in darkness, killed every last keyblade wielder, and split the X-Blade into seven lights and thirteen darknesses.
* The [[CoolShip Delphinus]] from ''VideoGame/SkiesOfArcadia'' is a possible example, but it's not entirely clear whether the weaker mass-produced equivalent (the Spectre-class battleships) are scaled-back mass production versions or the immediate predecessors of the Delphinus.
** The Delphinus was a proof-of-concept model, but doesn't necessarily fit the trope, and THE Flagship for the entire Armada- it was overkill for the reason of it being an AceCustom essentially.
* The fictional planes of ''VideoGame/AceCombat'' occasionally fall under this trope, particularly the X-49 Night Raven of ''VideoGame/AceCombat3Electrosphere'' and the ADFX-01 "Morgan" of ''VideoGame/AceCombatZeroTheBelkanWar'', which is a super prototype of the later (in the series original world timeline) and much more advanced ADF-01 "FALKEN". The Morgan zig-zags this, however, as the FinalBoss flies a Super Prototype ''of'' the Super Prototype (he gets an ADFX-0''2'' that carries all three special weapons at once while your -01 is stuck with one at a time), and then the later FALKEN is overall somewhat better (it only gets a fuel-air bomb instead of the multi-purpose burst missile the Morgan gets, but its [[FrickinLaserBeams Tactical Laser System]] carries more shots, holds the beam twice as long, and deals more damage per second).
** The real planes also have a bit of this. ''5'' in particular both subverts it (the F-15 S/MTD is better than the stock F-15 it was modified from) and plays it straight (the S-32 is better than the later Su-47).
** ''VideoGame/AceCombatXSkiesOfDeception'' brought us the Fenrir. The original models had optical camouflage, ungodly maneuverability and a microwave weapon. The production models don't have any of that aside from the ungodly maneuverability at the cost of ammo. In the same vein, the Varcolac from ''Joint Assault'' is shown to have a rear mounted machine gun that shoots down any and all missiles that approach it. In game, it doesn't have that but it's still the best plane in the game if you give it the right mods.
** Ace Combat's love of Super Prototypes reaches absolutely absurd levels in ''VideoGame/AceCombatInfinity'', which brings in no less than six variants of the [=Morgan/FALKEN=] line, - starting from a "Block 1" FlawedPrototype of the Morgan, on through the regular Morgan, through to Pixy's version with higher stats, then on to the FALKEN, and from there on to the ADA-01 ADLER, a ground-focused counterpart to the FALKEN, and the ''VideoGame/AceCombat2'' version of the original FALKEN.
* The Living Failures of ''VideoGame/{{Bloodborne}}'' is meant to be a FlawedPrototype of Celestial Emissary since the test subject failed to ascend into kins of the [[EldritchAbomination Great Ones]]. Despite how "failed" it sounded like, they are far deadlier than their successors and can [[MacrossMissileMassacre conjure meteors]]. One wonder why the Healing Church did not weaponise them instead.
* The Smithy Gang in ''VideoGame/SuperMarioRPG'' (Mack, Bowyer, Yaridovich and the Axem Rangers) are the super prototype models for their production lines. When you reach the last area, you discover that Smithy is creating an entire army of the bosses, though the machine-made versions are less powerful than the actual bosses.
* The Edelweiss in ''VideoGame/ValkyriaChronicles'', made by Isara's father for Welkin's father for the previous war. Unlike most super-prototypes.it was actually put forward to Gallian High Command. It was found to be an incredible tank, but it was [[JustifiedTrope too expensive for any kind of mass production]].
* Subject Delta ''VideoGame/BioShock2'' isn't just a Big Daddy -- he's the ''first'' Big Daddy; unlike the production models, he's nimble and has plasmid powers. It's justified in-universe by a whole host of problems with that particular series: they were too costly, their free will made them far more difficult to control, and are permanently bonded to a single Little Sister and doomed to death or violent insanity once she's gone. The newer models, while not quite as advanced, are physically stronger, more durable, and lack free will, and have no preference for any particular Little Sister, all of which better suit the one task they are built for.
** The ''Burial at Sea'' DownloadableContent for ''VideoGame/BioShockInfinite'' features a Bouncer Big Daddy that is able to launch its drill and pull enemies towards him. According to a chalkboard in Suchong's lab, this feature was removed because the hydraulic fluids/gases needed for this caused the Bouncer to become unstable.
* Vivi, like all Black Mages in ''VideoGame/FinalFantasyIX'', is an animated doll. However, as the prototype model, his power is greater than that of his "brothers", and his lifespan is much longer, as well.[[spoiler:Also in a far darker sense Kuja is a Prototype of the real Angel of Death Zidane, though it is arguable who is more powerful/competent]]
* A ContinuityNod in the ''VideoGame/ThunderForce'' series. The mass production model of Styx in ''III'' appear as {{N|onPlayerCharacter}}PC in ''IV''; The Rynex in ''IV'' has its production model appear in ''VI'' and also serve as prototype of Gauntlet in ''V''. It take MidSeasonUpgrade the Gauntlet into AceCustom Vambrace and MechaExpansionPack Brigandine module that Earth's fighter can fight the Rynex. It's justified since Gauntlet is Earthling's replica, built with alien technology they aren't fully understand.
* ''VideoGame/FinalFantasyVI'''s Kefka was the very first Magitek Knight (a normal human given magical powers by way of an infusion from an Esper). He consistently has much stronger magic then Celes, a later-generation Magitek Knight that joins your party.[[note]] The first time you fight him as a boss, he is Level 18, and has spells like Blizzara, Poison, Drain, and all three 1st level FireIceLightning spells. Celes would only have Blizzard, Antidote, Imp, Cure, and Scan at that same level.[[/note]] Unfortunately, as a prototype, he was exposed to an imperfect version of the infusion process, which resulted in him going just a teensy bit [[PsychoPrototype insane]].
* In the ''Compilation of VideoGame/FinalFantasyVII'', Sephiroth is a super prototype who is much stronger and more powerful than regular [=SOLDIERs=] and much more physically stable than the competing Project G prototypes Angeal and Genesis, who are subject to degradation. Unfortunately, Sephiroth could not be duplicated and he cannot replicate his genetic traits in monsters (like Angeal) or in humans (like Genesis).
* ''VideoGame/FrontMission 3'' has a couple interesting examples.
** In the start of the game your character is a test pilot for Kirishima Heavy Industries and your first mission is actually a final test run of a new prototype Wanzer for the Japanese Military. The Shunyo Mk. 111 is far more powerful than the test Wanzers you fight against.
** The true Super Prototype of the game, though, is the Hoshun. This is a Wanzer that [[spoiler:is somehow sent to you through the Internet]] and not only has more HP than any other pilotable Wanzer, but also has one of the only [[WaveMotionGun beam rifles]] in existence.
** Interestingly, the starting wanzer Kazuki pilots, the Zenith RV (misromanized as Zenislev), is the super prototype of the next game, Front Mission 4, obtainable in Elsa's scenario. Since 4 canonically happens before 3, this indicates how much Wanzer development has progressed.
* Prometheus, the last boss in ''VideoGame/{{Starsiege}}'' human campaign is the first [[AIisACrapshoot Cybrid]]. For the Cybrid campaign, you become one once you reach the highest rank.
* ''VideoGame/PhantasyStarZero'' makes fun of this trope to a degree. Occasionally you will find messages with tips in them. A message talking about a particular robotic enemy in that area says, "Production model & Prototype. Do we need to spell out which one is more powerful?"
* The backstory of ''VideoGame/VirtualOn'' provides both aversions and straight examples. Some prototypes like Viper Alpha and Proto Temjin have inferior armaments to their production model. Original Fei Yen is [[BonusBoss much more powerful than the production model]] but is sentient and eventually runs away from lab.
* Near the end of the first planet in ''KnightsOfTheOldRepublic'', you get to win a swoop bike race on a bike modified with a prototype accelerator. The adversary tries to deny your prize on the grounds that it was an unfair advantage, but the prize, being a Jedi, takes matters into her own hands by breaking out and killing most of the bad guys.
* In ''VideoGame/SidMeiersAlphaCentauri'', any prototype starts out one experience level ahead of a normal unit. This means that, with a Command Center and [[{{Cyborg}} Bioenhancement Center]], a prototype is Elite right off the rack. However, this is justified in the background material: Factions entrust their newest tech to their most experienced and effective troops and crews; the actual equipment is not significantly different from that given to subsequent units. Furthermore, prototypes take longer to build (unless the base has a Skunkworks facility), indicating the extra resources needed to work out the kinks. The actual equipment is probably not a prototype at all, just first-generation production with a best-of-the-best crew.
* ''VideoGame/{{Fallout 3}}'' has some really powerful prototype stuff. Example: MPLX Novasurge, a unique plasma pistol which greatly increases damage and the critical multiplier at the cost of doubled power usage and weight. It was developed by a "Section: A61" shortly before the Great War broke out. The prototype survived the war by being beamed aboard Mothership Zeta approx. 200 years before the Lone Wanderer found it in the ship's cargo hold.. Or the MP-47/A power armor prototype with a built-in medical dispenser and an onboard AI. And the Capital Wasteland's sole set of T-51b power armor(not counting the indestructible Winterized version from ''Operation: Anchorage''). Finally, there's Liberty Prime, a HumongousMecha built for the Anchorage Reclamation, but kept out of battle due to problems with its power supply.
** ''VideoGame/FalloutNewVegas'' shows that at least one prototype model of eyebots had a TV-screen, and not just a built-in radio. ED-E, however, is ''not'' quite this trope, despite being a prototype and much more powerful than its mass-produced cousins: it was the prototype to a series of combat-adapted eyebots that were scrapped in favor of Hellfire power armor, with the common eyebot being its predecessor rather than its successor.
** There's also the Tesla-Beaton Prototype, a unique Tesla cannon, and the AER-14, a prototype Laser Rifle with a green laser. The Q-35 Matter Modulator is an example and also has some backstory to {{retcon}} why the [=FO3=] plasma rifle is so different from the original plasma rifle (dubbed the "Plasma Caster" in NV): The plasma caster was too expensive, had an awkward form factor, and required too much training to be proficient in, so a military project was started to adapt it to a more familiar pistol grip rifle form factor, and lower the cost.
*** ''Old World Blues'' has the Stealth Suit Mark II, which like the Medic Power Armor, has an onboard AI that automatically dispenses Med-X and Stimpaks.
** ''VideoGame/{{Fallout 4}}'' adds the T-60 Power Armor, a step above the T-51 armor that was previously used. It was only beginning to be deployed experimentally (one of the Vault's military guards is wearing a suit of this armor in the pre-War sequence) when the Great War happened.
*** There's also a unique version of the Railway Rifle called "Prototype Railway Rifle". However, the player expecting it to follow the usual workings of this trope - and indeed of every other unique weapon in the game - will be disappointed: it gets subverted and does piddling damage, has poor range and only holds one round. [[RealityEnsues It behaves, in other words, exactly how you'd expect from an unfinished prototype.]]
*** As revealed in ''Far Harbor'', [[spoiler:Nick Valentine was one of the two prototype Synths capable of independent thinking and judgement, the other being [=DiMA=]. Rather than being junked by the Institute as he believed, he actually escaped alongside his "brother" [=DiMA=].]]
* A similar effect occurs with the ''VideoGame/SupremeCommander'' Experimental units. Any player will realize that these 'experiments' are always a great success, and utterly trounce dozens if not hundreds of the 'tested' units. And although you can build more than one of them, the too-expensive-justification is in full effect, as you need a very solid economy before you can start building one.
* Happens in ''VideoGame/StarCraftII'' where a prototype superweapon called ''Odin'' is stolen from the Dominion. It doesn't just have more hit points than any other unit in the game and do more damage than anything short of hero units -- it's also got several luxury amenities, including a restroom for the driver and an onboard nuke launcher. Rory Swann, the engineer of ''Hyperion'', says it's too impractical to mass-produce, at least with the facilities available to Raynor's Raiders, so a scaled-down machine called a Thor is slated for mass production. ([[GameplayAndStorySegregation Oddly, the Dominion seems to have agreed with Swann, as the Odin is one of a kind and the Dominion only ever fields Thors aside from it.]]) There's also the ''Loki'', a prototype for a new class of battleship, which boasts ridiculous firepower and toughness, completed at the same research station. The ''Loki'' at least is destroyed, which may be why that never went anywhere.
** The ''Loki'' may have been destroyed, but during the "Fire in the Sky" Zerg mission multiple similar looking Battlecruiser's appear, which may be the mass produced version to the ''Loki'''s super prototype. There's also the ''Pride of Augustgrad'', and the ''Jackson's Revenge'' mercenary ship, both of which look identical to the ''Loki''; the implication is that ''Jackson's Revenge'' is an old ship retrofitted to be competitive on the modern battlefield, an AceCustom of sorts, and perhaps the ''Pride of Augustgrad'' and ''Loki'' were test beds for normalizing such upgrades for the production models fought in the Zerg campaign.
* In ''VideoGame/CommandAndConquerRedAlert3'', the [[HumongousMecha King]] [[RealRobot Oni]] is a hulking behemoth capable of bull-charging enemy tanks and shoot EyeBeams for the glory of the [[UsefulNotes/ImperialJapan Empire of the Rising Sun]]. Apparently, the original King Oni is a super prototype, given to Emperor Yoshiro as a gift, which he uses when the enemy approaches his palace. It notably includes a set of Rocket Launchers for dealing with aerial threats, something the standard King Oni lacks. It's implied that this King Oni takes much more maintenance to take care of than the standard King Oni, but given that it's the ''Emperor's'' personal machine, no expense was spared.
** In the ''Uprising'' expansion, the Soviet Reaper unit is a super prototype for the Sickle. While the Sickle is only armed with machine guns, the Reaper boasts [[MoreDakka automatic grenade launchers]] and a [[MacrossMissileMassacre roof-mounted rocket launcher]]. However, unlike the Sickle, the Reaper's legs can barely support its weight and will snap off if it tries to leap like a Sickle. This is reflected in its special ability, which allows it to leap once and become a stationary turret wherever you want it to land.
* Played with by Prototype Jack in ''VideoGame/{{Tekken}}''. While it's unknown what happened between him and Jack (both survived the original tournament), P. Jack was soundly scrapped by Jack-2 in ''Tekken 2''. However, P. Jack's ability to fly was implemented in all subsequent playable Jack models.
* In ''VideoGame/{{Vanquish}}'', the ARS armor that Sam Gideon is wearing is a prototype of a new weapons system being developed by DARPA, and he is taking it along on the assault on Providence for two reasons: to test out its capabilities in live fire combat, and because the military is desperate for any weapon they can use to stop the colony's microwave array from being fired. In-game, it is indicated that the ARS has several limitations, primarily among them being that the suit will [[ExplosiveOverclocking explode if it overheats too much.]]
* The Excavated [[AMechByAnyOtherName ATACs]] in ''VideoGame/VanguardBandits'' are super prototypes from which all basic [=ATACs=] were reverse-engineered.
* ''VideoGame/CustomRobo'' is all about "ace customs" but your "super prototype" has a drawback for each advantage it has against mass produced robos of the same class.
* ''VideoGame/TheUnholyWar'' has a regular unit called Razorfane, a robot that attacks with circular saw blades. One of the secret unlockable characters is called Betarazor, which is basically just an upgraded version of Razorfane, with more health and more powerful attacks.
* ''Franchise/SonicTheHedgehog''
** Invoked (but not in any meaningful manner) in ''VideoGame/SonicHeroes''. One of E-123 Omega's combo-score quips is "Worthless consumer models!" Additionally, when he earns an E-Rank at the end of a stage, he laments that he couldn't even beat Gamma or Beta.
** Averted and then invoked in ''VideoGame/SonicAdventure'' by Omega's predecessor [[WhatMeasureIsAMook E-102 Gamma]]. During his story, he faces off against his older brother E-101 Beta for a spot on Robotnik's E-100 series of enforcer mechs and soundly defeats him in battle. Later on, [[HeelFaceTurn after revolting against Robotnik]], Gamma goes on a mission to destroy his brothers to save the [[LivingBattery animals trapped inside]]. After handily defeating all of his brothers, E-101 shows up again, having gotten a dramatic overhaul with abilities far surpassing Gamma's. Gamma is still able to defeat him without too much trouble, though Beta [[TakingYouWithMe sees to it that Gamma doesn't leave the battlefield]].
** ''VideoGame/SonicAdventure2'' has the Biolizard, the prototype ultimate life form which was enormous compared to its successor Shadow the Hedgehog. It was locked in suspended animation by GUN until Dr. Eggman reactivated it in the process of inserting the Chaos Emeralds into the Eclipse Cannon and [[ColonyDrop sent the ARK hurtling towards Earth]], after which it was defeated by Shadow but recovered and merged with the Eclipse Cannon in order to ensure that the colony would fall, only to be defeated again by the combined efforts of Super Sonic and Super Shadow. It is subverted in that the Biolizard seems to suffer from severe asthma, and even with a huge life support system attached to it, it can't sustain combat for half a minute without getting tired.
* The eponymous armor from ''VideoGame/{{Vay}}'' has been copied and mass-produced by [[TheEmpire the Danek Empire]] to create their massive robotic army. However, once the five magic orbs are retrieved and the Vay Armor's power is fully realized, it can stand toe-to-toe with almost anything Danek can throw at it.
* Subverted and played straight in ''VideoGame/HomeworldCataclysm'': the player ship ''Kuun Lan'' subverts it as, while the second of the two Explorer-class ships built by the Soomtaw, [[AllThereInTheManual has superior armour, engines and module capacity than the prototype due correction of design flaws discovered during construction]], while the Soomtaw Acolyte-class fighter plays it straight, as it's based on a Bentusi design that is slightly faster, has about five times its number of hit points and sports guns about twice as powerful.
* ''VideoGame/GranblueFantasy'': The Nightcypher, the speedship the crew uses in Platinum Sky, is ancient according to Sierokarte and lacks the fancy weapons that modern speedships have, but it has a powerful speed boost and it uses lost technology from the War, making it actually superior to its modern contemporaries.
* ''Franchise/{{Halo}}'':
** The Spartan-[=IIs=] are this to the Spartan-[=IIIs=] and [=IVs=]. The [=IIs=] tend to be larger, stronger, and just more naturally talented overall, due being subject to a much more stringent selection criteria than their successors. On top of all that, their [[PoweredArmor MJOLNIR armor]] is far better than the [=III=]'s SPI armor (though ''not'' the [=IV=]'s [=GEN2=] MJOLNIR). On the other hand, the [=IIs=] were also much more costly to produce and equip, and the process of augmenting them had a much higher failure rate than with the [=IIIs=] and [=IVs=], making them much fewer in numbers and much less expendable. ''VideoGame/HaloReach'' gives a good example of this trope. Putting aside the fact that Noble Team's Spartan-[=IIIs=] are something of an AceCustom (see that trope for details), Jorge (TheBigGuy of Noble Team and its only Spartan-II) towers above his Spartan-III squadmates and effortlessly carries a giant machine gun that would greatly encumber the others. (Granted, Jorge ''is'' a big guy even for his fellow [=IIs=].)
** The [=IVs=] are superior in both equipment quality and numbers compared to their [=III=] and [=II=] predecessors. However, while the [=IVs=] ''are'' highly-skilled volunteers drawn from the best veterans and recruits, the [=IIIs=] and [=IIs=] were both trained to be the perfect soldiers from ''[[TheSpartanWay childhood]]''; this difference manifests itself most clearly in the comparatively lesser skill and professionalism of the [=IVs=]. WordOfGod has also stated that the [=IVs=]' physical augmentations are inferior to those of their predecessors.
** Averted by the Spartan-I program, which did not have the success that the later programs did; if [[spoiler:Sergeant Johnson]] and the "[=1.0s=]" in ''ARG/ILoveBees'' are any indication, they're just slightly better than the best {{Badass Normal}}s. In fact, the Spartan program as a whole had to be renamed from "Project Orion" in order to distance the S-[=IIs=] from their predecessors (who themselves were retroactively renamed "Spartan-[=Is=]" to acknowledge they ''did'' provide the necessary data for the success of the later programs). Admittedly, the Orions ''were'' very effective soldiers, but just not quite good enough to prevent the Insurrection from spreading, not to mention that far too many of them started to experience severe degenerative side effects from the augmentations, both mental and physical.
** There's also the [[http://www.halopedia.org/HRUNTING/YGGDRASIL_Mark_I_Prototype_Armor_Defense_System HRUNTING/YGGDRASIL Mark I]] PoweredArmor, which was this to the [[http://www.halopedia.org/HRUNTING/YGGDRASIL_Mark_IX_Armor_Defense_System Mark IX "Mantis"]] MiniMecha. Whereas the Mark I had flight, rockets, chainguns, mines, a bubble shield, and ''a nuclear self-destruct system'', the Mantis usually only has a chaingun, a rocket launcher, and standard DeflectorShields; the latter's still a force to be reckoned with, though.
* ''VideoGame/{{Xenogears}}'' normally averts this trope, and hero Gears are usually either [[AceCustom Ace Customs]] or relics of LostTechnology. The one major case of a prototype that's clearly superior to the followup model is Grahf's Alpha Weltall, [[spoiler: which is built using 4000-year-old [[LostTechnology Lost Nanotechnology]] that can't be replicated in the modern world. Fei's Weltall is essentially a kitbashed knockoff designed by modern engineers, and is itself a FlawedPrototype; several of the compromises in the original design are patched out when Weltall is redesigned by Taura]].
* ''VideoGame/ShinMegamiTenseiStrangeJourney'' has the insanely overpowered ''Lightning'', which is in many ways a fully-retrofitted version of the game's standard dimensional-crossing warship. She's got even RealityWarper tech (too energy-consuming to move or deploy the plasma shield, but ''still''...) even in-game, the difference between the ''Lightning'' and the other ships is explicitly compared to a fully-tuned and upgraded car against one fresh from the dealership.
* Zigzagged in the ''[[Videogame/{{X}} X-Universe]]'' series. Prototype vessels tend to fare differently than their production versions, some having quirks that make them better or worse (such as higher weapon energy recharge but lower rudder speed). That said, some ships designated as prototypes fit the trope: The Paranid Hyperion Vanguard is a limited prototype run of Corvettes that far eclipses all other corvette classes (Among its many advantages, its the only one that can carry fighters and is either the top or tied for top in terms of speed, durability, and offensive potential amongst M6 vessels). The Hyperion Vanguard never entered full production run however (Which is why they cannot be bought by the player - only acquired through boarding existing copies). And all prototype ships, once they're acquired, can be reverse-engineered and then produced in the PlayerHeadquarters in practice like the factory-produced versions. The only ship that cannot be reverse-engineered is the Xperimental Shuttle, making it TooAwesomeToUse.
** In ''Videogame/XRebirth'', the player salvages a one-off prototype, the ''Pride of Albion'' (now the "''Albion Skunk''", [[WhoNamesTheirKidDude much to the chagrin of the pilot]]), which was designed to fight in the [[GuiltFreeExterminationWar Second Terraformer War]]. It's a hybridized ship combining the best features of both the old M3 Fighter and an M6 Corvette classes - it's maneuverable, very powerful, [[DroneDeployer carries a compliment of drones in a wide variety of flavors]], and one of the fastest ships around, but it was never put into mass production due to excessive production costs.
* As one might expect from a ''Franchise/{{Gundam}}'' game, ''VideoGame/GihrensGreed'' has its share of Super Prototypes. However, it plays the "production cost" angle brutally straight; building an army of Gundams is [[AwesomeButImpractical prohibitively expensive]], but a force of [=GMs=] will do the job at a fraction of the cost, so super mobile suits are best used as force multipliers in the hands of your aces.
** This is actually mentioned with the Prototype Gundam Mk-II's backstory: the machine was stupidly powerful and was made with performance over cost in mind; thus, when it was done, it was a machine that couldn't be piloted unless you were ''extremely'' skilled (or a Newtype) and it cost as much as a fleet of ''Pegasus''-class warships[[note]]That's the same class as the ''White Base''.[[/note]]
* Another ''Gundam'' game, ''The Blue Destiny'', features the three prototype Blue Destiny units, based on ''[[Anime/MobileSuitGundamThe08thMSTeam The 08th MS Team]]'''s RX-79(G) Gundam Ground Type units, extensively modified with a new control system. BD-1 used a GM head and was still ground-based, while BD-2 and BD-3 both sported Gundam heads and were modified for space use. Their control systems were based on a Zeon prototype, the MS-08TX(EXAM) Efreet Custom, whose designer defected from Zeon to the Federation.
** ''Blue Destiny'' received a pseudo-sequel called ''Missing Link'', which focuses on an offshoot of the EXAM project known as the HADES system. Only one prototype ever has the system installed: the RX-80PR Pale Rider. It's so powerful that the unit is still effective [[spoiler:10 years later, during the Neo-Zeon Wars, where it is finally taken down in a MutualKill with a Queen Mansa (one of the most successful Mobile Armor designs Neo-Zeon ever produced).]]
* ''{{VideoGame/Wipeout}}'' ''2048'' features unlockable prototypes which each has a huge drawback, but can be powerful compared to regular racers.
** The first unlockable Prototype: The Feisar Prototype, can exceed massive speed but it only speeds up when hitting speed pads.
** Second unlockable: The Auricom Prototype. It deals a decent amount of damage and doesn't get slowed down or wipes out when hit by a weapon. It can't pick up defensive weapons though and if you aren't careful, you won't notice when your craft is on low energy.
** Third unlockable: AG-Systems Prototype. Fast, ultra-agile and hard-hitting, but has the weakest shielding in the game.
** Fourth unlockable: Qirex Prototype. Sacrifices normal weapons for a special cannon which is even more powerful than the Plasma Bolt itself.
** Final unlockable: Pir-Hana Prototype. The fastest ship in the game hands down, but cannot steer without airbrakes.
* ''VideoGame/StarTrekOnline'' reveals that the prototype of the Advanced Escort ships, the ''U.S.S. Prometheus'' from ''Series/StarTrekVoyager'' was this, as the mass produced Advanced Escorts removed the Multi-Vector Assault Mode (which allowed it to separate it into three parts) due to parts being easy to damage. Then, they put it back for the special variants.
** For a fun thing, one of the purchasable add-ons is the NX prefix for all Federation ships. As it is cosmetic, there's nothing big about it beyond RP material, but with all the special high-ranking gear, you could pretty much say that you ''are'' flying a Super Prototype.
* ''VideoGame/WorldOfTanks'' is rife with this. Many of the more powerful vehicles are prototypes that were never produced in any significant number in RealLife, but any number of them can be used in the game. They also lack the flaws that made them AwesomeButImpractical in reality. Many of the tier upgrades are from real tanks to prototype upgrades that never saw service.
** To give you an idea of the extent of it, of the 32 Tier X (the most powerful. Count as of patch 8.10) Tanks/TD's/SPG's, ''three'' were ever mass produced, with one having just over 200 built.
** Although in most cases, the super prototype is a prototype ''of the next tank,'' where the next tank might be overpowered for gameplay purposes. For example, the Germans get prototypes of the Tiger, Panther, and Leopard tanks. The prototypes are tougher and perform better than any of their lower-tier vehicles in their tech tree... but do ''not'' perform better than the Tiger, Panther, and Leopard themselves.
* ''VideoGame/GuiltyGear'': Gears are artificially-engineered HumanoidAbomination {{Super Soldier}}s. The very first one ever created is leaps and bounds above the later ones in terms of power, [[OneManArmy cutting a swath through them and emerging unscathed in one encounter]], but he seems to be the only one of his type. This Gear is Frederick, the brilliant scientist who created the Gears in the first instance, [[spoiler:though he goes by the name Sol Badguy now]].
* ''VideoGame/NoMansSky'' features prototype spaceships in each of its three ship classes (Trader, Explorer, and Fighter) that are incredibly rare (not to mention extremely cost-intensive) but are leaps and bounds above most of the other ships you can find.
* The ultra-powerful Genesis Weapons wielded by the ARKS Council of Six in ''VideoGame/PhantasyStarOnline2'' are actually the first photon weapons ever made. Every usable weapon in the game utilizes the same technology but severely scaled back for mass production, as the original units are ''too'' powerful for most people to be able to control.
* ''VideoGame/ZoneOfTheEnders'' has the Orbital Frame Jehuty, an Orbital Frame in its own tier of power compared to everything else. Unfortunately, due to very bad luck, it was launched without 90% of its equipment drivers installed, leaving its performance at the bare minimum of its specs. Even then it tears through other Orbital Frames, including ones produced years later. The bad news is: the bad guys got Jehuty's brother unit Anubis... and Anubis is at its full power. Do not try fighting Anubis before Jehuty has unlocked all of its equipment... [[HopelessBossFight it will not go well at all.]]
* In ''VideoGame/AtlasReactor'' [[RobotDog PuP]] and [[WeCanRebuildHim Blackburn]] are both prototypes of their respective product line and superior to said product line. In both cases it's because they were [[AceCustom subsequently modified beyond their original product specifications]] and not because they were designed that way. [=PuP=]'s case is also reinforced [[LastOfHisKind by his remaining product line being destroyed by the AI ban]]; [=PuP=] surviving only because he was the FlawedPrototype at the time.
* ''[[Creator/ChoiceOfGames Mecha Ace]]'' has the [[HumongousMecha Lionheart]], which is both this and a FlawedPrototype. While it's superior in many ways to the bog-standard mecha, [[RealityEnsues it turns out]] that the piloting software has a bug in it that causes it to become unresponsive at top speed, requiring limiters that reduce its speed to fix. [[spoiler: On the Imperial side, there's the Roland]]
* In ''VideoGame/RiseOfLegends'', the Vinci faction has the Prototype Factory which allows the making of a SuperPrototype unit. While these types of units are individually unique, choosing to make one will lead to overall bonuses to units that the SuperPrototype was related to and these bonuses persisted even if the SuperPrototype unit was destroyed. For example, making the unique Siege Zeppelin will lead to all your Steam Cannons becoming more powerful. These SuperPrototype units are usually far better than the units that benefit from their development (such as the Siege Zeppelin to the Steam Cannons and Zeke the Robot to the Steam Fortress and Defense Tower).

[[folder:Visual Novels]]
* An interesting version of this is in ''VisualNovel/FateStayNight''. Gilgamesh has almost all the prototypes of every Servant's Noble Phantasm (exceptions include Berserker's [[BackFromTheDead God Hand]] and Saber's [[spoiler:Avalon]]), and goes on to explain exactly why his prototypes are that much more powerful. However, this is subverted in Unlimited Blade Works when [[spoiler:Shiro "traces" or copies all of Gilgamesh's super prototypes with his Reality Marble, essentially creating a water-downed mass production type version of each one; right after explaining although his versions are weaker imitations, there is no rule about the imitations losing to the originals, he states that he will prove his imitations are superior by destroying all of Gilgamesh's weapons and Gilgamesh himself. Cue CrowningMomentOfAwesome.]] It gets a little complicated after this. Gilgamesh's versions are actually more powerful in a one to one contest, but the copies can be spammed via a combination of ZergRush and TakingYouWithMe: "breaking" one of the weapons unleashes a very powerful attack (at the obvious cost of sacrificing the weapon) but since ''unlimited copies can be made'' this weakness no longer applies to them.
* ''VisualNovel/{{Demonbane}}'' has this trope play on two examples.
** First is the Destroyer Robot, while the prototypes are still far inferior to {{Magitek}}-based Deus Machina, at least it can withstand some beating. The mass production model can be destroyed by Demonbane's ''head vulcan guns'' and one of them even got disabled by [[BattleButler Winfield]], who punched through its sensor camera, ''on foot''.
** The second examples are [[TomeOfEldritchLore various grimoire]], their original appear as [[TokenMiniMoe little girl]]s with magic power, the copies are just books.

[[folder:Web Animation]]
* Averted in ''WebAnimation/{{RWBY}}''. In Volume 2, Team RWBY battle a prototype of the Atlesian Paladin hijacked by Roman Torchwick. With a bit of difficulty, the girls triumph and wreck the machine. When Weiss boasts this to Winter in Volume 3, Winter dismisses this, stating that the actual production models wouldn't be so weak as to fall to a team of first year Hunters-in-training. Sure enough, when the Paladins are hijacked again by computer virus during the Battle of Beacon, two of them give Weiss, Nora, Ren and the entirety of Teams CFVY, FNKI, SSSN and BRNZ an incredibly hard time and it's only thanks to Ruby's victory on the lead Atlesian battlecruiser than spares them from a third.

[[folder:Web Comics]]
* In ''Webcomic/TheAdventuresOfDrMcNinja'', uberninja Mongo, the result of early ninja gene experimentation, wields chainsaw nunchucks and has "All the speed, agility, martial arts ability [of a ninja], combined with giant like strength and general insane awesomeness." The reason they didn't make more? It's too expensive. [[spoiler: The "InverseNinjaLaw" is an actual in-universe force and the maker knows this, so that might also be a factor]].
* ''Webcomic/GunnerkriggCourt'' has a room full of them. Most notably, the first robot of the Seraph series, S1, looks much better than the more recent ones. And it has actual hands, rather than the simple claws of the later S models. The explanation given is that, since the original designer died, no one (not even the prototypes themselves) understands the cutting-edge technology underpinning them (for example, these robots have [[{{Magitek}} no visible power source, or motor, or means of moving their limbs]]). The robots were forced to simplify their designs just for future robot generations to survive. This trope is actually deconstructed in time. When one of the first generation robots is revived, he's impressed by the design of his descendants, because their simpler parts are more efficient and easier to repair.
* From ''Webcomic/GirlGenius'': The one or two Dingbots that Agatha has actually personally built, referred to as [[FanNickname Dingbot Prime]], are much better in every way than their successors. This is because most Dingbots are [[MookMaker built by other Dingbots]], and each generation has diminishing returns in quality, leading inexorably to this trope.
* According to ''Webcomic/{{Spinnerette}}'', the 1st Edition ''TabletopGame/DungeonsAndDragons'' sourcebook is indeed a magic book that the Drow-themed Evil Spinnerette uses to turn herself into a {{Drider}}.
* ''Webcomic/SonicTheComicOnline'' has a prototype for an advanced Guardian Robot called the Gizoid.

[[folder:Web Original]]
* The Brickspider Bot v1.0 of ''Roleplay/DinoAttackRPG'' is the original prototype of the Brickster-Bot Spiders that would later be mass-produced by OGEL Robotics, Inc. In comparison with the later models, the v1.0 is far more intelligent and cunning with its own distinct personality. This was deliberately toned down for the later models by its creators when they realized that something so intelligent would not want to act as a mere {{Mook|s}}.
* There's ''twenty-six'' Ilivais prototypes that fit this to a T in ''Literature/IlivaisX'' (well, twenty-five, as A is [[WeakButSkilled anything but "super"]]. They range from having slightly stronger weaponry to controlling six classical elements at once to being powered by a freaking PerpetualMotionMachine, but all of them are way more powerful than the MP units. The Aztecs hardly rely on them -- their tactics are built specifically to best make use of a OneManArmy unit.
* ''Literature/{{Starwalker}}'': Starwalker was built to test a new drive system.
* In the Dbagbo arc of ''Literature/TheSolsticeWar'' several prototype tanks appear and duke it out, making the battle a showdown between their respective R&Ds (and the ace tank pilots responsible for each prototype). Of these, the [[spoiler:Raktapata, an alternate universe version of the Soviet T-44 main battle tank a few years before its time]] is especially worthy of title, being seemingly indestructible if mechanically unreliable.

[[folder:Western Animation]]
* ''WesternAnimation/MegasXLR'' is both a super prototype and an AceCustom (so customized, in fact, that no one but Coop can pilot it, simply because he changed the controls that much). Megas was originally a Glorft design, [[GrandTheftPrototype stolen]] by Kiva.
* [[spoiler: The eponymous character]] in ''WesternAnimation/GeneratorRex''. [[spoiler:Rex's nanites]] come from an earlier batch that had already received full programming and testing. The nanites that were spread all over the world in the [[MassSuperEmpoweringEvent Nanite Event]] came from a later batch with incomplete programming.
** Alpha, the BigBad of the {{crossover}} with ''WesternAnimation/{{Ben 10}}'', is a prototype model control nanite from when the creators were still working out a way to control the nanites. Alpha is so powerful he has the potential to destroy the world ''single-handedly!''
* The main character of ''WesternAnimation/MyLifeAsATeenageRobot'' is notably much smaller than the previous robot in the XJ line. She {{lampshade|hanging}}s this in a late-series episode to which her creator explains that she had to cut down on her size to fit her personality in.
* ''WesternAnimation/RoughnecksStarshipTroopersChronicles'' has the Cybernetic Humanoid Assault System, or [[FunWithAcronyms C.H.A.S]]; when introduced, it's a walking tank with heavy armour, enough strength to tear trooper bugs apart in hand-to-hand combat, a number of armaments, the sensors of a bomb-sniffing robot, and an "adaptive learning AI" -- in essence, the ability to mentally grow and develop as a result of its experiences, something that leads it to performing a HeroicSacrifice. Later versions, seen in a couple of episodes, are pretty much MechaMooks and easily taken down by a single bug each. Justified when one remembers the end of the episode featuring the first [=C.H.A.S=] notes that the project was more or less scrapped because they were considered "less cost-effective" than human soldiers.
** [[SharePhrase Roughnecks HO!]]
* The [[TheDragon Delightful Children]] [[CreepyChild From Down the Lane]] in ''WesternAnimation/CodenameKidsNextDoor'' were the result of [[GoneHorriblyRight a botched experiment]] with the "Delightfulization Chamber". Essentially, the machine that made them so BrainwashedAndCrazy worked far better and the effects were rendered permanent, but because it was an accident the effect could never be replicated.
* In ''WesternAnimation/TransformersPrime'', Predaking, the first Predacon clone, is an absolute powerhouse in battle, and [[ItCanThink turned out far more intelligent than his Decepticon handlers expected]]. The other Decepticons began to regard him as a potential threat, rather than an asset. The next two Predacons, Skylynx and Darksteel, were made dumber so they could be more easily controlled, and Predaking was able to defeat both of them at once in a fight.
* ''WesternAnimation/StarWarsRebels'' features a prototype of the B-Wing starfighter from ''Film/ReturnOfTheJedi''. It has a powerful superlaser cannon that can take out a cruiser in one or two shots, but has several power issues that readily explain why the ones we see in the film don't. The film version also has a large magazine of proton torpedoes as well, which allows a different form of heavy firepower.
* In ''WesternAnimation/PhineasAndFerb'', Norm's prototype head is capable of a wider range of emotions than the final model and doesn't speak in a monotone, but is a lot snarkier.

[[folder:Real Life]]
* As a general rule of thumb, there are two types of prototypes: concepts that barely work, and just demonstrate what the finished product could be; and stuff that has more buttons and features and flashing lights than you can imagine, and is prohibitively expensive or complicated to make on a wide scale. Super Prototypes are the latter category.
* On expos showing new cars or military technology, the displayed products will almost always have superior stats or better looks than the finished versions. This however is because said prototypes, while more powerful, may have their stats so highpowered they become self-damaging from simply doing anything. Hence finished versions have to be toned down.
* Military prototypes coming out of less technologically-advanced countries often fall under this trope. The prototype is often hand-crafted by a procession of engineers and scientists that have access to extremely complex high-precision tools, thus granting superior performance. When the designs hit factory lines, though, such precision tools are often unavailable, and mass-production tends to favor production efficiency over precision. This can be mitigated by good quality control, but in desperate war-time situations, such steps can and will be skipped over in favor of increased production. For example, take the [=A6M=] Type Zero, the (in)famous WWII Japanese fighter. Without sufficient factories to meet wartime needs (Many suitable factories had been destroyed by US strategic bombing), high school students were occasionally conscripted for manufacturing purposes. Ultimately, this led to a significant amount of unusable parts, aircraft that were sometimes barely able to fly, and aircraft that would come apart during normal use.
* Performance automobiles enter this arena. It's not unusual for the actual prototypes to a new sports car to begin as non-functional mockups (sometimes even clay sculptures) to test things like aerodynamics and weight distribution. However when the vehicle is shown off at highly prominent car shows, automakers will reveal a pre-production model with body options and engine features that are not street legal, exuberantly expensive to manufacture, inherently dangerous (no safety equipment or pollution control), and even one-of-a-kind. These things can make the show car have performance capabilities above and beyond what the consumer would get from the production version without major aftermarket modifications.
** One particular example was the [[https://en.wikipedia.org/wiki/Jaguar_XJ220 Jaguar XJ220]], unveiled as a concept for a car show and never intended for production, but so many were prepared to buy one they decided to modify it to make it suitable for production, taking deposits of fifty thousand pounds, non-refundable, locking buyers into contracts to oblige them to buy the final product at three hundred and fifty thousand pounds. The concept had everything a man in crisis could want - V12 powerplant to rival the Italian supercar brands, scissor doors, 4-wheel-drive, 4-wheel-steering; three years later Jaguar tells you the car has only rear-wheel-drive, front-wheel-steering, normal doors, and the engine is now only a V6 with awful turbo-lag, and the price had actually ''increased by over forty thousand pounds''. You were given the option of buying your way out of the contract. Try to sue and the court will find in Jaguars' favour. Really, they wouldn't, under the right conditions, have ever needed to deliver a single car. World economic problems added to this, and eventually only 275 cars out of a projected 350 were built, and not all of them sold.
* Bell P-39 Airacobra, whose prototype had powerful armament and turbosupercharger. USAAF wanted the production aircraft without the turbo and heavily armoured, reducing the performance dramatically.
** Subverted with the Lend-Lease Airacobras supplied to the USSR. Because the Soviets used them in a completely different role (as low-altitude frontline fighters, instead of the high-altitude escorts), the lack of turbocharger didn't bother them much, as it mainly affected the high-altitude perfomance[[note]]And the Soviet mechanics uprated the engines anyway by reboring them and increasing the compression this drastically shortened their service lives, but with the Easter Front attrition rates very few planes survived even this shortened period anyway.[[/note]], but Soviet pilots appreciated the heavy armor and powerful armament very much. In the Soviet Union Airacobra turned out to be the AcePilot machine, and most of the Allies best aces flew P-39 during some part of their careers, but the original prototype probably wouldn't shine there so much, as it was geared for the different mission.
* The United States Navy's first six sailing frigates after it was re-established with the Naval Act of 1794 exhibit this trope, both among themselves and in relation to the Navy's later fighting sail. The first three of the six--''United States'', ''Constellation'', and ''Constitution''--were completed first. The latter three--''Congress'', ''Chesapeake'', and ''President''--were put on hold for several years, but then completed and launched during the Quasi-War with France. ''United States'', ''Constellation'', and ''Constitution'' account for ''all'' of the victories against foreign warships attained by the six frigates. To add insult to injury, ''President'' and ''Chesapeake'' were the only ships of the six to be ''defeated'' by foreign warships--and ''President'' was a "half-sister" to ''United States'' and ''Constitution'', having significant modifications to her design which made her faster than her predecessors!
* The world's first Nuclear Powered Aircraft Carrier, [[http://en.wikipedia.org/wiki/CVN-65 USS Enterprise (CVN-65)]] was a one of a kind super prototype of the later Nimitz Class carriers. Equipped with '''8(!)''' nuclear reactors[[note]]because the output of the nuclear reactors available at the time wasn't high enough to allow for a single reactor design, and also because it was seen as only natural that the 8 boilers of a conventional supercarrier would be replaced by 8 reactors in a nuclear supercarrier[[/note]] and advanced electronic systems on a unique square island structure the "Big E" was later surpassed in displacement by the Nimitz carriers, but remained the longest military vessel in the world until her retirement in 2013. The excessive cost of the Enterprise and its 8 reactor layout resulted in the Navy shelving the nuclear carrier concept with proposed sister ship USS ''America'' being re-ordered as a conventionally powered ''Kitty Hawk''-class carrier and the USS ''John F. Kennedy'' also being converted to conventional propulsion during construction. The US Navy would not commission another nuclear carrier until 13 years later in 1975.
** ''Enterprise'' is the subject of a number of rumors about having an UpToEleven top speed due to her large number of reactors with 50 knots the figure typically being cited. These are generally untrue with Enterprise achieving a 35 knot maximum speed like the fastest carriers with a conventional powerplant, however the 8 reactor plant allowed Enterprise to generate steam more quickly than her successors or her escorts[[note]]In the 1960s most ships still used steam and rapid-acceleration gas turbines were a new, relatively rare technology.[[/note]] allowing for faster acceleration and less competition for steam between the catapults, electrical generators and engines.
** One major advantage the ''Enterprise'' did have over conventionally-powered ships was that her nuclear power plant could not only move her very quickly (the ''Iowa'' class battleships were the only conventionally-powered surface ships in the fleet that could match her speed for any distance, as ships benefit from the SquareCubeLaw), but could also do so for a ''very'' long time, as the fuel capacity for her nuclear reactors was measured in decades. Even though similarly-sized conventional carriers could keep pace with her, they still had to stop to take on more fuel, while ''Enterprise'' could dedicate the extra carrying capacity to carry more fuel and munitions for her air wing.
* USS ''Lexington'' (CV-2) and her sister Saratoga had numerous features that many other aircraft carriers wouldn't see for decades to come. Most notably they featured an enclosed "hurricane" bow that reduced wind interference during flight operations. Another first was the placement of the smokestack directly behind the island, a feature that her successor, the USS Ranger, didn't replicate. They also bolstered more flight deck space than any of America's other wartime carriers.
* The Pennsylvania Railroad was known to have built more than a few super prototype locomotives which were then never duplicated or scaled back for production. One of these was the [[http://en.wikipedia.org/wiki/PRR_FF1 class FF1 electric locomotive]] which was built in 1917 to test concepts related to electrifying steep mountain grades. Equipped with 4 1150hp synchronous AC motors the unit, nicknamed "Big Liz", developed a then astonishing 140,000 pounds of tractive effort. Unfortunately Big Liz turned out to be an example of TimTaylorTechnology. When pulling trains her power would pull out the couplers. When reassigned to pusher service Big Liz pushed with so much force that on one test train cars began to pop out of the middle. Big Liz was simply too much power in one locomotive for 1917 rolling stock.
** The other PRR example was the [[http://en.wikipedia.org/wiki/PRR_S1 class S1 duplex steam locomotive]] with its distinctive design became TropeCodifier for 1930's art deco streamlined locomotives even though only one was ever built. The longest steam locomotive ever built, the S1 [[TooAwesomeToUse spent its first two years of life on display at the 1939/40 New York World's Fair]] before being released to service. Designed to haul 1000 tons at 100 mph it frequently was capable of much more, but [[AwesomeButImpractical its great length restricted it to service on one section of main track]] between Crestline, OH and Chicago. It also had a nasty wheelslip problem that could destroy the running gear in seconds if not quickly corrected at high speed. The 52 production T1 class locomotives were much less ambitious while still providing stellar performance.
** In the UK, the [[http://en.wikipedia.org/wiki/GER_Decapod Great Eastern Railway Class A55 Decapod]]: a steam locomotive built to match the acceleration of then-current electric trains. Built to prove a political point, the design never went into production.
** Zigzagged with the [[https://en.wikipedia.org/wiki/BR_Standard_Class_8 British Rail Standard Class 8]] passenger steam locomotive. Only one was built, 71000 ''Duke of Gloucester'', and performed poorly in service, burning too much coal and not producing enough power. Since BR was planning on getting rid of steam in the near future, it was decided not to go through the expensive and extensive engineering process of improving the ''Duke'', which was withdrawn after only eight years of service. It was rescued from the scrapyard, however, and during its restoration it was found that the deficiencies were caused by minor flaws in design of certain elements, as well as [[ExecutiveMeddling certain features being altered or omitted on the order of higher-ups]]. With these flaws corrected, the ''Duke'' is not only one of the most efficient steam locomotives ever built, but is significantly more powerful than the diesels that replaced it.
** The Intercity Experimental, prototype predecessor to the Intercity Express of UsefulNotes/DeutscheBahn, had a lot of features that would only be seen in revenue service decades later or never. It also had a higher top speed (which is an EnforcedTrope, as trial runs in Europe have to be done with the top speed +10% to give a safety reserve)
** There were trial runs with prototype electric trains in 1903 on a military railway in Prussia that was equipped with prototype overhead wires for that purpose. The trains reached 200 km/h, but none of them ever entered revenue service and neither did the electrification system.
** The British [[https://en.wikipedia.org/wiki/Advanced_Passenger_Train Advanced Passenger Train]] holds several records that have yet to be broken by regular trains on British Rails. It was plagued with trying to do too many things at once and ultimately killed by politicians who had expected it too early (meaning it was rushed to market before it was ready) and then complained of its "greenness". Some of the patents, notably that for active tilting were later sold to Italy and used to develop a new class of Pendolino tilting trains that have been sold - to Great Britain among others.
* Early models of a new-concept product such as a digital camera, being designed by-geeks-for-geeks, can sometimes have advanced features (foldout screens, own programming language) which get dropped in later models as the product goes mass-market. This can lead to howls of dismay from enthusiasts, who were expecting a new model to improve ''everything'', only to find that a choice feature has been removed to save money or dumb-down the product for the average consumer.
* The Soviet WWII era T-34 tank plays this trope straight, subverts it and generally [[ZigzaggedTrope zigzags]] it ten ways to Friday. Initial prewar batches of it were more carefully built and better outfitted than the wartime construction, but the model 1940 variant with its petrol engine suffered various engine-related teething problems that made them difficult to use, quite unreliable and the maintenance hogs to boot.[[note]]The early air filters that basically failed to filter any air come to mind, as well as the transmission that required such force to switch that there was a popular joke about that T-34 drivers were easier to jump over than maneuver around due to the cramped space tankers ''do'' tend to be short, [[DoNotExplainTheJoke but the training made them so much wider]].[[/note]] The model 1941 with the famous and reliable Kharkiv V-2 engine was brought into production and the T-34S variant with a three-man turret was tested as a prototype, but once the war started, the Soviets couldn't afford refitting the production lines to the T-34S variant. Wartime production models were incredibly rushed, crudely finished to the point of sometimes forgoing the ''paint'', but the design itself was polished and improved. It didn't help that there were significant quality differences between the vehicles at different factories, with those from Factory 183 being the best and those from Factory 112 being notoriously unreliable. And then in the midst of a war the real Super Prototype tanks was designed, the T-43, which was a sort of answer to the Pz.V Panther and addressed all of the T-34 flaws than remained unsolved but the realities of the war time made sure that it never was mass-produced, because it still was inadequately armored and doing so would once again mean stopping the assembly lines for as much as a whole ''month'', meaning some thousands of T-34 wont get to the frontline. Instead, all of its features that could be applied to the T-34 without stopping the production (like a new transmission and new variant of the V-2 engine) were transferred to the old workhorse model along with a new, three-man turret, resulting in the definitive T-34-85 model.
** The T-100 was this to the KV series of tanks, having [[MoreDakka double turrets for twice the fire power]]. This made it restrictively top-heavy, and the weapon was eventually converted into a [[{{BFG}} more practical SPG]].
* Frequently happens in wartime with things that are going to be mass produced. A good example would be submachine guns. Both the Sten and MP-40 prototypes were carefully machined and had carved wooden furniture. When it came to the production models the wood gave way to wire and the guns were made by anybody with the ability to bash metal.
* The MBT-70 was the direct precursor to the famous [[TankGoodness Leopard II and M1 Abrams]] main battle tanks, and for a while was technically superior to both. The catch? The fact that it required a practical PHD in engineering in order to operate meant that [[AcePilot only a select number of people could operate it]], and it certainly wasn't reasonable to devote a whole base of logistics for only a dozen tanks. The other problem was that the Germans and Americans at the time had incompatible ideas of what they wanted out their next main battle tank, which was why the American version of the MBT-70 carried a [[{{BFG}} 152mm rifled gun]] that was also capable of launching missiles while the German version used a 120mm smoothbore gun that only fired shells. (In the end, both armies used the German gun for their later tanks, so if not for Pentagon stubbornness a further-developed and simplified MBT-70 probably would've worked out fine.)
* When the Russians in TheOughts decided to develop a new Main Battle Tank, they pulled out all stops, the final result being an object 195 (better known as T-95) prototype. With its [[{{BFG}} 6" cannon]], an unmanned turret, radar, the 30 mm AntiAir gun and all high-tech gizmos the money could buy, it turned out [[AwesomeButImpractical too large, too heavy and, most important,]] [[TooAwesomeToUse too complex and expensive]] to build more than a handful. Unsurprizingly, it was canceled in 2010, with most of its usable features migrating to a still very ambitious, but notably more reasonable object 148 (AKA T-14 Armata) MBT, first displayed in May 2015.
* The M-26E1 "Super Pershing" (It's even in the name!) fits this to a T. A new model with an upgraded gun the very first pilot model was rushed into battle straight from the factory late in the war amid continuing calls for tanks with still more firepower to battle the very heaviest German vehicles[[note]]Stories about it having defeated a King Tiger in battle, while awesome, have been proven untrue by combat records.[[/note]]. Only this single unit was ever deployed in combat however and was then further modified by its mechanics by having scavenged armor welded onto it to improve protection before being assigned to an elite crew.
* The one-of-a-kind [[UsefulNotes/KatanasOfTheRisingSun WWII Japanese]] ''super'' destroyer "[[https://en.wikipedia.org/wiki/Japanese_destroyer_Shimakaze_(1942) Shimakaze]]", armed with ''15 torpedo tubes'' and 6 5-inch guns plus a top speed of 42 knots thanks to an experimental engine. Being the most powerful destroyer in the world was useless against the air attack that sank her in 1944.
* The demos for some games can fall in this category, showing graphical effects not present in the final product. One example was {{VideoGame/WatchDogs}}, with rain and lighting effects shown in its E3 trailer {{DummiedOut}} of the PC version. Sometimes this is for sound technical reasons like causing performance problems on anything but a very specific combination of hardware or just using too much processor power for all but the most expensive kit to run acceptably, but sometimes ExecutiveMeddling plays a part; in the case of the aforementioned ''Watch Dogs'', it's been alleged that the game was downgraded at the insistence of Sony and/or Microsoft because they didn't want to hurt console sales by having the PC version look better, as modders have successfully patched these effects back in and found them to work fine even on mid-range hardware.
* Pre-release versions of the Kinect, a camera accessory for the [=Xbox=] 360, included a relatively beefy built-in processor to handle its functions without taking resources away from game performance. The processor was stripped out at the last minute to reduce the cost, making the final version much less versatile.
* The US Navy's ''Seawolf''-class nuclear attack submarine was originally meant to be a larger production run meant to replace the predecessor class in that role, the ''Los Angeles''-class. Instead, only three were made. The ''Virginia''-class, a more cost-effective (though not quite as capable) evolution of the ''Sea Wolf'' is instead slated to replace the ''Los Angeles'' class. and already have four times the number of the ''Sea Wolf'', with many more planned.
* The [[RareGuns Heckler & Koch G11]] is an experimental assault rifle which uses caseless ammunition, it has a slow full auto firing mode and an ''absurdly quick and accurate'' three round burst mode. It also looks [[OurWeaponsWillBeBoxyInTheFuture boxy and futuristic]] thanks to its unique loading mechanism. Unfortunately, despite being a huge success, the cost inefficiency has terminated its production.
* The [[CoolGuns/MachineGuns MG 34]] was the predecessor to the famous [[CoolGuns/MachineGuns MG 42]] [[note]]Not exactly a prototype but close enough in spirit[[/note]]. The MG 34 featured both a sturdier construction than its successor and was capable of sustaining a higher rate of fire. It also had a innovative crescent double trigger that allows the user to change between firing semi and full auto without the need of a selector switch. The 34 was to expensive and time intensive to manufacture so Germany designed the easy to manufacture 42 to take its place.
* Even merchandise isn't immune to this trope. For example, a plush toy of the Hunter from ''Franchise/HalfLife'' was made. Look up a picture of the Hunter, then look up the plush. Now, look up the more accurate and arguably more superior prototype of said plush.
** Toys in general tend to go through this, as the prototypes that eventually get used as the basis for the production molds are handmade and consequently tend to feature better paint jobs and sharper details than the finished versions. This is especially common in ''Franchise/{{Transformers}}'', due to the complex engineering involved and the somewhat inconsistent budgets - for instance, compare the [[http://tfwiki.net/mediawiki/images2/b/b3/Leobreakerearly.jpg prototype claw mode]] of Leobreaker to that of the [[http://www.unicron.us/tf2005/toypix/leobreaker3b.jpg retail release]]. This overlaps with FlawedPrototype, however, as they're made of resin and therefore quite fragile.
* The infamous Power Glove's original proof of concept, the Data Glove, functioned near perfectly and could do far more than the final product. The problem was the design was ''way'' too pricey to make than would be profitable, and the designers only had five months to reduce the price to reasonable levels, resulting in the flawed final product.
* Occurs with videogame consoles where the prototype or launch models have features that are then scaled back on later versions, usually for cost reasons. The first [=PS3=] consoles includes backwards compatibility, but subsequent units lost this feature. Or how the first Xbox 360s featured internal hard drives, whereas later ones required a customer to spend more than $100 to buy their own separate Xbox hard drive.
* The Rocketdyne F-1 (the engine that powered the Saturn V rockets) to every U.S. rocket engine since then. It was so powerful that the first examples built, scaled up from existing rocket designs, were unable to stand up to the force they were delivering and literally ripped themselves apart on the test stand. To test their stabilizing capabilities, NASA essentially built a grenade launcher to fire explosives into the rocket plume while the engine was running. Each individual flying F-1 engine was hand-built and hand-tuned, making the whole production run of fifty engines a series of Super Prototypes designed to work with four other Super Prototypes in concert.
* The Super Foonly F-1, whose famous application was rendering the CG in ''Film/{{Tron}}'', was the most powerful PDP-10 minicomputer ever made. However, only one was ever produced; DARPA withdrew funding for the project, and later computers produced by the Foonly company were slower and less efficient.
