** It later appears in "Slumbering with the Enemy". Mojo Jojo threw it at the title superheroes in said episode to reduce them to normal little girls, though this [[SnapBack obviously doesn't affect subsequent episodes afterwards, since the Girls inexplicably get their powers back for the next episode]].

'''Hanna:''' No--it ''does'' nothing.

** The first we see is "The Haitian" the powered company agent paired with the none-powered Noah. His ability is to nulify the abilities of everyone within a certain range, paired with memory wiping via skin contact.

** The second eclipse completely nullifies everybody's powers. It's stronger than the Haitian's power, as it reduced Daphne to a crippled state, while she was able to walk around the Haitian. Claire also starts dying of common bacteria, due to not having an immune system from her HealingFactor. %% Do not argue about plot holes here. Those go on the series' headscratchers page. %%

* ''Series/StargateSG1'' has the Anti-Prior device the team cooked up against the Ori. It emits an inaudible sound that makes Priors unable to use their psychic powers; however, both Damaris and [[spoiler:Daniel Jackson/Merlin]] were able to overcome it given sufficient time.

* ''Series/{{Survivor}}'' introduced one in Season 37 in the form of an Idol Nullifier. A person possessing this advantage can cancel out the effects of a person playing an idol under the requirement they can correctly guess who will play an idol at that tribal council.

* Vanya's pills in ''Series/TheUmbrellaAcademy'',combined with brainwashing that she doesn't have any powers. The pills suppress her emotions, as they [[PsychoactivePowers fuel her abilities]]. She was also placed in an anechoic chamber as a kid, because sound is the other fuel source for her powers, unfortunately that doesn't work in the present since her heart is always beating.
* ''Series/TheWheelOfTime'': Channelers can block others' using the One Power, though the more powerful are very difficult to.

** ''Film/Deadpool2'': Dangerous Mutants sent to the Iceblock prison are fitted with electronic collars that neutralize their powers (already seen above). Russell can no longer shoots blasts of fire, and Deadpool loses his HealingFactor. This is actually [[DeathByDepower life-threatening in Wade's case]], since it also means his cancer is no longer kept at bay and can spread unchecked. [[spoiler:Despite this, Deadpool willingly puts such a collar on at the end to make a genuine HeroicSacrifice for Russell.]]

* Wiki/SCPFoundation's SCP-514. Whenever in contact with the pigeons' nullifying "aura", every weapon (bombs, guns, tanks, baseball bats, knives, etc.) is rendered completely useless and are even destroyed after prolonged exposure. Even objects not designed to be weaponized like pens were rendered useless if used for violent intent. In addition, the pigeons' ability can completely suppress the negative emotions and intent of all sentient beings, no matter how violent, which makes the capture of SCP-514 nearly impossible.

** Antidote X, the antihesis of Chemical X, first appeared in "Mo Job" as part of Mojo's plan to permanently remove the girl's powers after he is hired by Princess. It is loaded into a laser and fired at the girl's but never directly hits them. The gun is broken at the end of the episode after the beam is deflected back at Princess.

* ''Manga/HybridXHeartMagiasAcademyAtaraxia'': The Batlantis Empire has several restraints like collars and cuffs as well as cells that stop people from using their powers. The restraints can be dialed down to let prisoners use some of their powers, like when the Empire forced Kizuna and Grabel to face each other in GladiatorGames so they could entertain the crowd but not generate enough force to escape. The two manage to escape by [[DeusSexMachina engaging in foreplay on the arena floor]] until they generate so much energy they overload and burn off their cuffs.

* In ''VideoGame/MonsterHunter'', Dragonblight nullifies any elemental or status damage caused by the Hunter's weapons.
** "Elderseal", a weapon characteristic added in ''World'', prevents Elder Dragons from using some of their more powerful attacks and can cancel out their auras and abilities.

* ''Manga/{{Bleach}}'': There's a type of stone in the Soul Society called Sekiseki stone. It's used for the prison tower Rukia was in during the SS arc and also the wall around fortress of the 13 Court Guard Squads. This is why its so difficult for prisoners to escape and also for intruders to break in.

Related to PowersAsPrograms. For countering supernatural powers, see AntiMagic. If the power has already been used, DispelMagic can remove the effects. PowerLimiter is a weaker version. NoSell is when a character ignores, not nullifies, another's powers. {{Mage Killer}}s often weaponize this ability, as they do with AntiMagic. See also the KryptoniteProofSuit, which can be used to resist {{Weaksauce Weakness}}es. A type of MetaPower.

* A common thread in ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fan fiction is the need for these sort of devices, typically a ring or other covering placed on a unicorn's horn as a law enforcement restraint on unicorn magic (although one ends up in ''Fanfic/WildSweetAndCool'' as sports equipment). Effectiveness varies; one fic might have a simple ring work on any pony, even PhysicalGod Luna, while another might have various grades (including one which MELTS when Twilight Sparkle is pissed off sufficiently).

* In the ''Franchise/StarWars'' fanfic "[[https://www.fanfiction.net/s/1759755/1/Can-What-is-Lost-be-Found Can What Is Lost Be Found]]", Obi Wan Kenobi is captured, and when he's rescued, he has a device attached behind his ear to prevent him using his Force abilities. The healers are cautious about when to remove it, as they fear Obi Wan may lash out and hurt himself or someone else if he doesn't know what's going on before it's attmepted.
* Another ''Franchise/StarWars'' fic, "[[https://www.fanfiction.net/s/4928281/1/Misplaced-Jedi Misplaced Jedi]]", has an older Obi Wan captured and when Anakin rescues him, he's got a collar around his neck to keep him from accessing the Force.

** It has the "Neut Cuffs" that the cop in New Zork puts on Paul to nullify his Ability. Too bad for him that [[spoiler:Paul was specifically built by Jeft so his powers couldn't be nullified, since if they were, he would explode from the energy he contained.]]

* ''Fanfic/TheDevilsInTheDetails'': When Matt and Peter agree to work together to allow Vision to live and stay on Earth while removing his infinity stone, Dr. Strange gives Matt a relic that dulls his senses so that he can share a room with Vision without suffering from SensoryOverload.

** The skill "Nihil" / "Mikiri" in the [[VideoGame/FireEmblemJugdral Jugdral]] and [[VideoGame/FireEmblemPathOfRadiance Tellius]] sagas. In the Jugdral games, it nullifies all enemy Critical Hit-based, and Special Sword skills; in the Tellius games, it negates all enemy Battle skills. The Tellius games have in addition the Skill "Parity", which has the same effect but extended to the Skill's owner as well, and also negates both the skill's owner and his foe's support and terrain bonuses.
