A fairly common subtype of settings with a MassSuperEmpoweringEvent in the backstory. Each superpowered person gets one power. Some powers are [[SemanticSuperpower more versatile]] [[SwissArmySuperpower than others]], of course. The ''only'' exceptions are people whose one superpower is [[PowerParasite the power to copy or steal powers]]. ''Nobody'' gets ComboPlatterPowers as a default.

Subtrope of OneSuperOnePowerSet, but more restrictive.

%% ''Anime/CodeGeass''
%% ''Manga/{{Aphorism}}''
* The Contractors in ''Anime/DarkerThanBlack'' follow this rule strictly. Some of them even explicitly lack RequiredSecondaryPowers.
%% ''Anime/WitchHunterRobin''
* In ''Manga/OnePiece'', there appears to be only one of each Devil Fruit, and nobody can have two Devil Fruit powers (except [[spoiler: Blackbeard]]). Trying to will result in the death of the person trying to obtain the second power. Averted with Haki, which can be learned by anyone and used in tandem with Devil Fruit powers or other abilities.
%% ''Manga/{{Bleach}}''
%% ''Manga/{{Needless}}''
* ''LightNovel/ACertainMagicalIndex'' and ''Manga/ACertainScientificRailgun''
** Espers always only have one power but the versatility of this power can vary. Electromasters control electromagnetism, which allows for LightningCanDoAnything, but Meltdowner essentially creates plasma and is mainly only useful for destructive purposes. The absolute king of this is Accelerator, whose Vector Control can do literally ''anything'' that involves movement, from stopping bullets to '''slowing the planet's rotation by borrowing some of its kinetic energy for a MegatonPunch'''.
** In-universe urban myths exist about Dual-Skill and Multi-Skill people, with a single (temporary) example of the latter appearing in ''Railgun''.
** [[TheHero Touma]] is a special case here, as his [[AntiMagic Imagine Breaker]] is actually sealing away another power [[spoiler:that might or might not be of divine origin]].
* ''Anime/TigerAndBunny's'' heroes all have different powers, and it's considered surprising when Barnaby is introduced with exactly the same power as Wild Tiger. However, another NEXT having the same or similar powers is a known phenomenon. Wild Tiger was inspired as a boy by a hero who had the same power he did and nobody makes anything if out when his daughter initially seems to develop the same power.
* In ''Manga/AliceAndZoroku'', those who possess the "Dreams of Alice" are {{Reality Warper}}s whose power is themed around a certain "Card", allowing for varying versatility. One of a pair of twins creates a simple bow and arrow while her sister can create anything with a chain, ranging from actual chains to bicycles to wrecking balls.
* It's stated in ''Manga/BokuNoHeroAcademia'' that humans can only be born with one power (called quirks), however characters like Todoroki can have multiple facets of their quirk (in his case, he has [[PlayingWithFire fire]] and [[AnIcePerson ice]] powers). The concept of someone gaining multiple quirks is a running plot device.
** It's possible for people to gain more than one quirk through unnatural means, however since the human body is not designed to handle this, this comes with severe medical side effects, usually insanity, physical mutations, or mental retardation. The only two people who are the exceptions to this are [[spoiler: All for One and his unnamed younger brother, the former because his quirk specifically allows him to do this, and the latter was implied to just be lucky.]] It's implied that if someone with a quirk inherits One for All, they will either be able to wield their quirk along with One for All, or One for All will assimilate their other quirk.

[[folder:Comic Books]]
* The "White Event" in ''ComicBook/TheNewUniverse'' played this fairly straight.
* ''ComicBook/{{Lanfeust}} de Troy''
* ''ComicBook/PowerPack''
* Notably subverted in ''ComicBook/XMen'' with secondary mutations.

* The eponymous ''Literature/{{Children of the Red King}}'' usually have only one 'endowment' each. A few characters have been shown to have two; only one person seems to have had more than that.
* The ''Literature/{{Nightfall}}'' books by Mickey Zucker Reichert feature individuals with single "natal talents".
* The supers in ''Those Who Walk in Darkness'' and ''What Fire Cannot Burn'' by Creator/JohnRidley all have strictly one power each ({{flight}} is an exception that works strangely). This became a major plot point in the latter book.
* The ''Literature/{{Xanth}}'' books fit this trope.
* In ''Literature/{{Graceling}}'', the Gracelings each have one Grace (which is either a skill at which they are superhumanly proficient or an outright superpower.)
* The psychic children of the ''Gotterelektrongruppe'' in Ian Tregillis' ''Literature/BitterSeeds'' and [[TheMilkweedTriptych sequels thereof]].
* The Magicals/Actives of ''[[Literature/TheGrimnoirChronicles Hard Magic]]'' all have one power each, albeit with RequiredSecondaryPowers included.
* ''Literature/{{Gone}}'' by Michael Grant features several superpowered kids with a single power each, with the eventual exceptions of Brittney, Drake, and [[spoiler: Gaia]].
* In ''Literature/ShadowOps'', "Latents" (humans who develop magical powers) only develop within one specific "school" of magic. Some of these are limited, i.e. pyromancers can only create fire. Others are impressively diverse, such as terramancers, who can control earth, shape and grow plants, and mind-control animals.
* ''Literature/TheExtraordinaryAdventuresOfOrdinaryBoy'' has an entire city with this.
* ''Literature/StrengthAndJustice'': One [[MagicByAnyOtherName dyna]] per person.
* By the time of ''Literature/WaxAndWayne'', the magical bloodlines have diluted such that there are no more Mistborn or Feruchemists: nobody has more than one Allomantic and one Feruchemical power. Twinborn are those with one of each, and Compounders are Twinborn with matching powers--which, due to a quirk of the magic system, means that they can get more out of their Feruchemy than they put in, breaking the EquivalentExchange and creating an infinite loop. The only Compounder in the first book is Miles Hundredlives, who uses gold to store health and get a HealingFactor that makes Wolverine look like a wimp.
* Pretty much true in ''Literature/SuperPowereds'', although [[MindOverMatter telekinetics]] are invariably [[PsychicPowers telepaths]] as well. It's thought that the two are really variations on the same ability. Some powers are more versatile than others. Most Supers are [[VoluntaryShapeshfiting Shifters]], requiring them to switch to their alt-mode in order to use their powers. That alt-mode can be ''anything''. Some are lizards, some turn into themselves with metal skin, some are robots with missile launchers and flying capability. Extremely-powerful elementals are able to take on certain characteristics of their element (e.g. a Super's mastery of electricity also allows him to attain SuperSpeed). Some Supers don't have a power that is useful in combat, such as Nick, who can manipulate luck (most combat isn't based on luck). However, as shown in ''Year 1'', at full power, even his ability can have devastating results ([[spoiler:when using it to stop a truck on a highway, he manipulates the luck of the vehicle to simultaneously cause half a dozen improbable malfunctions that nearly rip the truck to shreds]]).

[[folder: LiveActionTV]]
* Each witch from ''Series/{{Charmed}}'' possesses a unique "active power" in addition to their basic powers of spell-casting, potion-brewing and scrying. They can range from telekinesis, creating fire, super speed and even invisibility. The Charmed Ones are an exception as they all start with one power and naturally gain new ones as they advance.
* ''Series/TheFortyFourHundred''
* ''Series/{{Heroes}}'' has this for all the heroes. It's just that a couple of them have the single power of stealing/copying other people's powers.
* ''Series/MutantX'' does this with the exception of [[BigBad Gabriel Ashlocke]], who had ''every'' power.
* ''Series/{{Misfits}}'' subverts this. Although everyone seems to get one power, at least two people were given two powers in the storm, and Seth can give customers multiple powers with his ability.
* ''Series/{{Alphas}}''

* ''Film/{{Push}}'': Powers are categorized into the following:
** Mover: [[Main/MindOverMatter Telekinesis]]
** Pusher: [[Main/MindManipulation Mind Control]]
** Watcher: [[Main/{{Seers}} Precognition]]
** Bleeder: [[Main/MakeMeWannaShout Sonic Scream]]
** Stitch: [[Main/HealingHands Healing]]
** Wiper: [[Main/LaserGuidedAmnesia Mind Wiping]]
** Shadow: [[Main/{{Invisibility}} Invisibility]]
** Shifter: Illusion-casting
** Sniffer: [[Main/{{Psychometry}} Psychometry]]

* ''Film/SkyHigh2005''. While Nurse Specs mentions that its ''possible'' for the child of two superhumans to inherit ''both'' of their parentsí powers, the implication is that its damned rare, and everyone else's reactions to Will's not only being [[FlyingBrick super-strong but being able to fly]] implies that most people only have one power.

* In ''Webcomic/{{Sidekicks}}'' all supublics are born with a [[SuperpowerLottery single superpower]]. Superheroes subvert this by gaining a second superpower thanks to their [[SuperheroesWearCapes hero]] [[BadassCape capes]] and the villains working with Metheos do so [[spoiler:via the Third Prana.]]

[[folder:{{Web Original}}]]
* In the ''Roleplay/GlobalGuardiansPBEMUniverse'', this is how most superpowers work... while a person might have several abilities, they are usually just variants and special-purpose uses of their one superpower.
* Most descendant powers work this way in ''Literature/TheDescendants.'' There are exceptions, but they're rare enough that the fact that magic users don't conform to this rule is an immediate tip off that something is stranger than usual about them.
** The series gets away with FlyingBrick, FlyingFirepower, and FlightStrengthHeart by lumping them into either ElementalPowers of a kind of InvoluntaryShapeshifting called 'protomorphism'.
* ''{{Literature/Outliers}}'' subverts the trope; while the first generation of supers only got the one power (although they tended to be fairly broad to make for it), the second generation often get multiple, including some FlyingBricks.

[[folder:Western Animation]]
* In the universe of ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', every pony, Unicorn, Pegasus, and Earth, has a "special talent" that grants them anything from a proficiency in a fairly mundane task such as making other ponies happy to legitimate superpowers such as supersonic flight or the ability to easily use any form of magic.
