History Main / KeystoneSuperpower

* ''ComicBook/JokersLastLaugh'' features the mutant Multi-Man, whose "core" superpower is the ability to [[DeathIsASlapOnTheWrist resurrect after death.]] Every time he does, though, he gains a new superhuman ability. It's definitely a case of BlessedWithSuck, as both the villains and heroes repeatedly kill Multi-Man (which still hurts) until he's revived with a power useful to their plans.

* ComicBook/{{Vixen}}'s Tantu totem allows her to mimic the abilities of animals. This translates into flight, breathing underwater, poisoning someone with her touch, enhanced strength, enhanced speed, and even the ability to ''regenerate from a few cells'', among other things.
* ''Franchise/XMen'':

* ''Manga/JoJosBizarreAdventure'': Many [[FightingSpirit Stands]] grant SuperStrength (or at least strength surpassing the average human) to their user via an apparition that can fight for them, on top of the Stand's special power. A good example is [[Manga/JojosBizarreAdventureDiamondIsUnbreakable Crazy Diamond]], which is supernaturally strong and fast while also giving Josuke [[HealingHands healing powers]].

* The main character from the ''Franchise/{{Persona}}'' series has this as their stock ability in every game. Every other persona user in the game has access to only one persona they can use in battle that reflects their [[BeneathTheMask hidden or true self]] they may not reveal in public. Personas therefore follow a motif related to the character and have abilities in line with that motif like ShockAndAwe, AnIcePerson, PlayingWithFire, etc. The main character however has access to any standard persona and can stock up to 12 personas at one time to use interchangeably. A bit of FridgeBrilliance since the main character is also the player character and is portrayed as an EveryMan AudienceSurrogate for the player to project themselves onto, thereby making their "true self" dependent on the player.

* In the ''Film/XMen'' series, like her comic book version, Rogue has the ability to drain a person's energy by touching them. Absorbing a mutant's energy allows her to temporarily take on their power.

** ''Series/KamenRiderDecade'': Decade's primary power is to shapeshift into any other main Kamen Rider, letting him use all of their powers. Diend has the similar main power to summon clones of up to three other Riders, which lets him use their powers by proxy.

* ''Webcomic/GrrlPower'': Varia's "gestalt" power isn't quite PowerCopying, but she does gain powers related to those she's touching, such as magnetism from Jiggawatt or cryokinesis from Heatwave.

* Jack-Jack Parr in ''WesternAnimation/TheIncredibles'' seems to have ComboPlatterPowers such as EyeBeams, {{Intangibility}}, [[MesACrowd self-duplication]] and VoluntaryShapeshifting. In [[WesternAnimation/Incredibles2 the sequel]], Edna Mode identifies Jack-Jack as a "polymorph" to explain his wide variety of powers; Shapeshifting is his true power, but he can shapeshift at a ''molecular level'', letting him rewrite his own genetics to let him have whatever power he wants.

* ''TabletopGame/VillainsAndVigilantes''. The Weather Control ability allows the owner to use several other powers by summoning a specific type of weather: Darkness (clouds), Lightning (thunderstorm), Vibratory (tornado), Sonics (hurricane), Ice Powers (snow/blizzard).

* ''LightNovel/ThatTimeIGotReincarnatedAsASlime'': Rimuru Tempest possesses the skills Predator, allowing him to [[CannibalismSuperpower copy the abilities and transform into any creature he eats]], Great Sage, a nigh-omniscient guide that can tell him almost anything about the world, and Pain Nullification, which allows him to FeelNoPain. Combined, it gives him the ability to develop endlessly.

* Jack-Jack Parr in ''WesternAnimation/TheIncredibles'' seems to have ComboPlatterPowers such as EyeBeams, {{Intangability}}, [[MesACrowd self-duplication]] and VoluntaryShapeshifting. In [[WesternAnimation/Incredibles2 the sequel]], Edna Mode identifies Jack-Jack as a "polymorph" to explain his wide variety of powers Shapeshifting is his true power, but he can shapeshift at a ''molecular level'', letting him rewrite his own genetics to let him have whatever power he wants.

** The provider for the page quote, Emiya Shirou, can only use projection magecraft properly. [[spoiler:But thanks to this, he can copy the Noble Phantasm of every hero he encounters, granting him their skills alongside it. He can also make the projections have the same power as the original for one attack, a technique called Broken Phantasm. By Shirou's own admission, he could never stand up to a Servant like Saber who dedicated themselves to one weapon even with this power. But his power to project, combined with his Reality Marble Unlimited Blade Works, is the perfect counter to Gilgamesh's Gate of Babylon, as demonstrated in the Unlimited Blade Works route.]]

* On ''WesternAnimation/JusticeLeague'', the android A.M.A.Z.O can scan and copy any power. The first empowered beings with which he came into contact were the Justice League members themselves, which alone granted him flight, super speed, super strength, shapeshifting, the ability to form hard light constructs, and telepathy. Eventually, over time, he amassed enough powers to give him nigh-omnipotence. When the League (which had since [[HeroesInc dramatically increased its numbers]]) and the Green Lantern Corps had learned that A.M.A.Z.O was returning to Earth from its intergalactic travels after having seemingly destroyed planet Oa, not a single one of them were able to so much as slow him down when they attempted to intercept him.

** Arthur Petrelli, can absorb powers from any Evo. By absorbing the powers of his son, who posses PowerCopying, he gains a vast arsenal of Evo abilities.
** Peter Petrelli, Arthur's son, has PowerCopying, granting him the power of any Evo near him, permanently.

* ''Franchise/Ben10'': Ben only has the Omnitrix/Ultimatrix. But it allows him to shape-shift into any alien recorded in its database. Each alien has powers ranging from SuperIntelligence to RealityWarping.
* On ''WesternAnimation/JackieChanAdventures'', the demon [[BigBad Shendu]] has ComboPlatterPowers because of his [[ArtifactOfPower Twelve Talismans]], each of which grants him a different ability ranging from SuperStrength (the Ox) to SuperSpeed (the Rabbit). But after he's [[TakenForGranite imprisoned in a statue]], the Rat Talisman becomes the Keystone: its unique gift is "Motion to Motionless," which can turn anything into an AnimateInanimateObject and thus allow him to access the other Talismans.
* On ''WesternAnimation/JusticeLeague'', the android Amazo can scan and copy any power, which eventually gave him nigh-omnipotence.

** ''VideoGame/CastlevaniaChroniclesOfSorrow'': Soma Cruz has the ability to [[YourSoulIsMine steal the souls of the demons he kills]] and [[PowerCopying copy their abilities]]. This means that he's potentially capable of using the powers of anything in the castle, even though he technically has only one ability.

** [[Characters/MarvelComicsLegion David Haller]] has the ability to create spontaneous mutations, granting him a virtually limitless number of mutant abilities. He has over 200 "Omega Level Mutations" and more are being created constantly. For comparison, about a dozen omega-level mutants are known to exist.

** The eponymous character has the ability to copy the [[WeaponOfChoice Signature Weapon]] of every Robot Master he defeats through his Variable Weapons System. [[ComicBook/MegaManArchieComics The comic book]] and [[WesternAnimation/MegaManRubySpears TV show]] depicted him copying the weapons of other robots with a simple touch.

** Tohu, one of the [[{{Kaiju}} Endbringers]], can copy the powers of up to three capes at a time. One of her three heads will change to resemble the cape she's copying. [[{{Munchkin}} She copied Eidolon]] in her first appearance, allowing her to use five powers. [[spoiler:In the final battle, she copied Eidolon ''and'' Glaistig Uaine after she had claimed Eidolon; this gave Tohu two copies of Eidolon's power plus two more of Glaistig's ghosts, with one more slot left over for a third copied cape, [[UpToEleven for a total of nine powers]].]]

** [[Characters/XMen80sMembers Rogue]] has PowerCopying and can absorb the powers, memories, and skills of any person she touches. The length of time for which she has access to these abilities is directly proportional to the length of time she touches the person, something she tries to avoid seeing as she's technically draining the life energy of everyone she touches, not just copying their abilities, and therefore can outright kill someone if she's not careful. Her trademark super-strength and flight that she's had since her debut she actually got from permanently absorbing the abilities of [[Characters/MarvelComicsCarolDanvers Ms. Marvel]].

* In ''Fanfic/ImaginarySeas'', Percy's Noble Phantasm, Poseidon Asphalios: An Ocean of Blessings for the Most Beloved, grants him access to every skill used by a child of Poseidon but ''better'' by virtue of raw ParentalFavoritism as Poseidon's favorite son. This Noble Phantasm also grants him access to Poseidon's own Noble Phantasms, including the armor that [[NighInvulnerability makes him invincible]] so long as he's by the ocean and [[ProngsOfPoseidon the trident]] that Poseidon uses to exert his Authorities over earth and sea. His skill, Savior of Olympus, also gives him the right to use any Mysteries of Ancient Greece and Rome due to saving the Greco-Roman Pantheon time and again.

** Glaistig Uaine is a somewhat roundabout example of this trope. She can drain the essence of recently deceased parahumans (or living parahumans, which [[TouchOfDeath kills them]]). She can then conjure ghostly figures which look like her claimed victims, complete with the powers they had in life, which are fully under her control. Like Eidolon, she can only have up to three ghosts active before their powers start to weaken.
