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 the power to copy or steal powers. ''Nobody'' gets ComboPlatterPowers as a default.

Subtrope of OneSuperOnePowerSet, but more restrictive.

!!Examples:

[[foldercontrol]]

[[folder:AnimeAndManga]]
* ''CodeGeass''
* ''{{Aphorism}}''
* The Contractors in ''DarkerThanBlack'' follow this rule strictly. Some of them even explicitly lack RequiredSecondaryPowers.
* ''WitchHunterRobin''
* In ''OnePiece'', there appears to be only one of each Devil Fruit, and nobody can have two Devil Fruit powers (except [[spoiler: Blackbeard]]). Averted with Haki, though.
* ''Manga/{{Bleach}}''
* ''{{Needless}}''
* The Espers from ''LightNovel/ACertainMagicalIndex'' and its spin-off ''Manga/ACertainScientificRailgun'' 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]].
* ''{{Tiger and Bunny}}''
** Well, ''almost'' everyone...

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

[[folder:{{Literature}}]]
* The ''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 ''[[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 ''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.
[[/folder]]

[[folder: LiveActionTV]]
* ''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.
* ''MutantX'' does this with the exception of [[BigBad Gabriel Ashlocke]], who had ''every'' power.
* ''{{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}}''
[[/folder]]

[[folder:{{Film}}]]
* ''{{Push}}''
* ''SkyHigh''. 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.
[[/folder]]

[[folder:{{Web Original}}]]
* In the ''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'.
