History Main / PowerNullifier

* Yukimaru's special ability in the second game of the ''{{Disgaea}}'' series has a chance to inflict the Amnesia Status, which seals specials. The cockatrice generic in {{Disgaea3}} has this as its innate evility, but they have to stand next to the enemy to make it work.

* In ''Webcomic/{{Kubera}}'', the Sword of Re is a god-level item designed to fight [[OurDemonsAreDifferent sura]]. It inhibits the [[HealingFactor regeneration]] of anything it strikes (specifically, it brings it down to normal human regeneration, which is basically nonexistent), from sura to gods, making them far easier to kill. While most sura and any god could [[OnlyTheWorthyMayWield easily wield the weapon]], the problem is that it does the same thing to the ''owner'' as well, and the only way to give up the sword is to die. This makes it a perfect weapon for a human, but every sura who has tried to use it has inevitably died quickly and messily.

-> '''Gerrard:''' But it doesn't ''do'' anything!
-> '''Hanna:''' No--it ''does'' nothing.

* in ''XenobladeChronicles'' Egil has a device called the Apocrypha made in order to disable Shulk's [[LaserBlade Monado]], shorting out it's ability to damage his [[HumongousMecha Face Mechon]], and all it's other powers.

* Gold Kryptonite could permanently remove the powers of Comicbook/{{Superman}} and [[{{Supergirl}} other Kryptonians]], and exposure to a red sun would do it temporarily, as would some varieties of Red Kryptonite. It was brought back after 20+ years but its effects are only temporary. This makes it less scary but more useful as a plot device: depowering Supes forever isn't an option, but you'd be surprised how long fifteen seconds is when you're depowered and a superpowered nutjob is trying to [[MemeticMutation kill you to death]].

* In the {{New 52}}, Rose Wilson emits a field that turns off invulnerability in her presence, which allows her to fight people like {{Superboy}}.

* ''SupermanII'' allowed {{Superman}} to become "permanently" human by absorbing an extremely large dose of red solar radiation. When the Phantom Zone villains arrive on Earth, however, he regains his powers by consuming the energy stored within the Fortress of Solitude. (This is only revealed in the director's cut; the original version has a DeusExMachina transition between Superman staring at a crystal and reappearing fully powered).

** The country of Genosha's mutant-power-nullifying collars and a power-nullifying mutant named Wipeout. Remember that thing about a character who wants to be able to turn their own power off not bothering to use the technology available? With brilliant scientists all over the MarvelUniverse, there's no reason Rogue couldn't get a collar modified into a stylish necklace with an on/off switch. [[{{natter}} This has been addressed in various continuities and adaptions so we're not going to argue about it here.]] The short of it is sometimes prolonged user causes damage or Rogue premanently copied Mis. Marvel's FlyingBrick powers so he copes better.

* ''LightNovel/ACertainMagicalIndex'': Touma's AntiMagic "Imagine Breaker" right hand also serves as a PowerNullifier if it is touching the person in question. He can't be teleported by Kuroko at all, either, no matter where they are touching; nor can telepaths send his brain messages ([[spoiler:Though Shokuhou Misaki, Academy City's Number Five, seems to have figured out a way to bypass Imagine Breaker with her Mental Out, though it will still be nullified if Touma touches his head with his right hand.]]). Unfortunately for him, it also cancels blessings and anything else that might have granted him good fortune, [[BornUnlucky leaving him with bad luck.]]

Unfortunately for him, it also cancels blessings and anything else that might have granted him good fortune, [[BornUnlucky leaving him with bad luck.]]

* The ''KamenRiderDouble'' film ''Double Forever A-Z/The Gaia Memories of Fate'' had [[spoiler:a new evil Rider named Eternal. Eternal's Maximum Drive FinishingMove initially was capable of permanently disabling any old-generation Gaia Memory, regardless of whether they were a Rider's or a Dopant's.]]

* [[http://www.fictionpress.com/s/3112491/1/The-Lay-of-Paul-Twister Paul Twister]] has "the Twist," the ability to screw up active magic by touch. It's apparently [[PowerIncontinence not under his conscious control]], and he remarks several times [[InformedFlaw (though it's yet to be shown)]] that the Twist is not perfect and doesn't make him invincible against magic.

** sekiseki, a mineral which blocks reishi, is why Soul Society cannot be invaded; it blocks any and all forms of spiritual power.

** [[spoiler: PsychopathicManchild Wonderweiss was created to counter the abilities of [[BadAssGrandpa Yamamoto]]]].

* Andy Hinomiya's esper power in ''Anime/TheUnlimitedHyoubuKyousuke''. His ability makes him an outcast among both muggles and espers. It also makes him [[spoiler:a fairly effective double agent, since he is immune to psychometry and mind reading]].
* Characters in HunterXHunter are able to learn [[FunctionalMagic nen abilities]] that disable other people's nen. The two shown so far are Kurapika's Chain Jail (which will kill the user if it's used on anyone other than the [[CarnivalOfKillers Phantom Troupe]]) and Knuckle's Hakoware (a [[LoanShark bank loan-themed]] ability that actually ''makes the target more powerful'' with each hit, but accrues interest every ten seconds, shutting off the target's nen for a month if they go over a certain limit and "bankrupt.")

Curiously, very few people who say IJustWantToBeNormal create a modified version of these for their own personal use, even if the technology seems to be relatively available.

* In TabletopGame/DungeonsandDragons, spell "Mordenkhainen's Disjunction" can strip magic permanently from magic items. Also fits this trope in that, if a spellcaster successfully strips the power from an Artifact-level magic item, the caster himself permanently lose all magic related abilities and spellcasting.

** So did the copycat ''Zoom's Academy''.

* The ''KamenRiderDouble'' film ''Double Forever A-Z/The Gaia Memories of Fate'' had [[spoiler:a new evil Rider named Eternal. Eternal's Maximum Drive FinishingMove initially was capable of permanently disabling any old-generation Gaia Memory, regardless of whether they were a Rider's or a Dopant's.]]
* In {{Hancock}}, [[spoiler: he and Mary]] are this to [[spoiler: each other]].

* [[CiemWebcomicSeries Ciem 3]] has hand bracelets that are used on Centhuen Prototypes, as well as Marlquaan field freezers in the greater Gerosha universe of Dozerfleet Comics. Male Centhuen Prototypes are [[TheUnfairSex infinitely harder to keep captured]], since they [[MisterSeahorse can't get pregnant]]. Females' bodies are merely tricked into thinking they're pregnant, and the body hits its own off switch on powers from there.
** Marlquaanites are [[AppliedPhlebotinum powered by]] the [[NegativeSpaceWedgie Marlquaan]] and [[MetaOrigin its link to them]]. As such, without [[SealedEvilInACan a containment field]],they are unstoppable.

* In ''{{The4400}}'', Jordan Collier's ability is to depower others by removing the [[{{Phlebotinum}} promicin]] that gives them their powers.

* ''StationeryVoyagers''
** [[OurAngelsAreDifferent Levio the Nullifier]], who functions as both this and AntiMagic. Wizards are reduced from casting spells with impunity to any number of side effects: casting spells with [[CallItKarma karmic backfire]], [[CastFromHitPoints casting from hit points]], or the humiliation of a specific spell simply not working. If it were not [[BecauseDestinySaysSo necessary for Mechanical Pencils to exist to fulfill certain prophesies]], then Levio would be allowed to block the process of [[UnwillingRoboticisation Artificial Reincarnation]] as well.
** Likewise, [[{{Magitek}} muellexic techonlogy]] has allowed for [[PsychicPowers phantomars]] to be disabled on Stationeries with the aid of certain devices, effectively serving as a sort of replacement for handcuffs in a world of creatures that don't have hands.

** sekiseki, a mineral which blocks reish, is why Soul Society cannot be invaded; it blocks any and all forms of spiritual power.
** Rukia's gigai makes its wearer invisible to sensors by nullifing reish
** [[spoiler: PsychopathicManchild Wonderweiss was created was to counter the abilities of [[BadAssGrandpa Yamamoto]]]].

* [[BigBad Father]] of ''Manga/FullmetalAlchemist'' can negate the powers of Amestrian alchemists by stomping his foot. He does this by [[spoiler: creating a cushion made of souls that reside in Amestris]]. Xingese alchemy works differently so he can't stop it or the kind used by Scar.
