** ''Heroic Menace vs Evil Menace:'' This is often used as a {{justifi|edTrope}}cation to why the heroes, who either are this kind of monster/alien, can [[{{Animorphism}} turn into one]], or [[KidWithtHeRemoteControl have one under their control]], can seriously wail on the MonsterOfTheWeek, and yet the [[FiveRoundsRapid military forces and]] [[PoliceAreUseless police are still useless]] - though if this becomes a trend, it may lead to [[TheMainCharactersDoEverything other characters being unable to affect the plot in a meaningful way]] or even turn those connected to the monsters into a SpotlightStealingSquad. If the heroes are forced to become this type of monster to win, expect a MyGodWhatHaveIDone moment afterwards.

A subtrope of MutualDisadvantage. An opposite of TacticalRockPaperScissors where each type of combatant has some other capable of [[CurbStompBattle curb stomping]] it. Compare BeatThemAtTheirOwnGame, HoistByHisOwnPetard and SummonBiggerFish. Contrast LikeCannotCutLike.

A subtrope of MutualDisadvantage. An opposite of TacticalRockPaperScissors where each type of combatant has some other capable of [[CurbStompBattle curb stomping]] it.

* In ''Anime/TheBigO'' one of the few things that can damage a [[GiantMecha Megadeus]] is another [[GiantMecha Megadeus]], though this is less an issue of compatibility than a matter of sheer firepower. There have been several organic threats which could have legitimately beaten a Megadeus.

* In ''Manga/{{Claymore}}'', the eponymous warriors are humanity's only hope against the yoma--because they are infused with yoma blood to gain control over yoki, their demonic energy. On the flip side, all Claymores run the risk of turning into ''super'' yoma, a.k.a. Awakened Beings. [[spoiler:However, the beings the Claymores were really meant to fight are the Dragon-people whose flesh is the source of yoma.]]

* In ''Manga/JoJosBizarreAdventure'', a Stand (an invisible telekinetic construct) can only be harmed (inflicting [[{{Synchronization}} sympathetic damage]] on its creator) by another Stand. Although some Stands can't be harmed at all. However, a Stand ''User'' is just as vulnerable to being killed by mundane means as anyone else (which of course, will usually [[{{Synchronization}} destroy the Stand]]).

* A variant is used in ''Manga/TokyoGhoul''. [[HunterOfMonsters Ghoul Investigators]] hunt Ghouls using a weapon called a Quinque, which is made using a Ghoul's [[ShapeshifterWeapon kagune]]. The audience learns this when Kureo Mado brings out his Quinque to kill [[SacrificialLamb Mrs. Fueguchi]], who recognizes it as having been [[KickTheDog made from her husband]]. Later on, he brings out his newest Quinque to attempt to kill her daughter -- he had it made from Mrs. Fueguchi after killing her. However, this is the ''most effective'' way of fighting ghouls available to humans. They could, theoretically, beat them to death with their bare hands, but ghouls have a physical edge in that area.

* ''ComicBook/TheBoys'': The Homelander is basically Superman with none of Superman's positive traits. In order to make sure they could control him, Vought apparently raised him next to a nuke, and [[spoiler:cloned him, raising the clone for the sole purpose of taking out the Homelander so as to have a loyal equivalent in case of betrayal. Unfortunately, the clone (Black Noir), being unable to carry out the mission it was created for, took matters into its own hands by filming itself committing atrocities so the Homelander would think he'd committed them.]] When the Homelander finally snaps, rebelling and killing Vought's puppet president, [[spoiler:Black Noir]] finally gets to intervene.

* Implied in ''VideoGame/TronTwoPointOh''. In that universe, human "Users" digitized and sent to {{Cyberspace}} are almost {{PhysicalGod}}s. With one corrupted User unleashing a ZombieApocalypse over multiple computer networks, and the people behind ''him'' about to upload an army of mercenaries to conquer the computer world so they control the human one, [[BenevolentAI Ma3a]] resorts to this logic and uploads the protagonist in desperation.

* The titular {{Mon}}s of Webcomic/BattleKreaturez are protected by invisible ReinforceFields that spike in response to duress, making them NighInvulnerable. Compounding this, they also have a [[HealingFactor]] that allows them to recover from most injuries. This means a rampaging Kreature can only reliably be stopped by another Kreature, necessitating the art of Kreature Taming.

Added DiffLines:

* In ''Film/LeftForDead'', the only thing that can destroy the demonic ghost Mobius Lockhart are his own weapons: a pair of pistols he claims were forged in hellfire.

Added DiffLines:

* ''WesternAnimation/FinalSpace'': Implied in "The First Times They Met" with the evil [=KVN=]s. They are stated to be nearly indestructuble, which is demonstrated throughout the episode, but towards the end the main KVN easily kills the last one himself by [[AndShowItToYou punching right through him and tearing out a vital heart-like component]].


** When you start messing around with the ElementalRockPaperScissors, you may start getting combinations of types that wouldn't normally resist themselves paired with a type that is weak to said type -- like how the Fighting/Steel Lucario is weak to Fighting, the Bug/Grass Parasect is weak to Bug, and the Steel/Ground Steelix is weak against Ground. [[note]]These types are: Ground, Fighting, Flying, Rock, and Bug. No, Normal doesn't count.[[/note]]

* The [[EvilKnockoff Another Riders]] fought by ''Series/KamenRiderZiO'' have ResurrectiveImmortality. Their KryptoniteFactor is the power of the Kamen Rider they're based off of, but a side effect of their creation [[RetGone RetGones]] the original Rider's story.

[[spoiler:Series/KamenRiderDecade could presumably also do the job, but he spends most of the series pretending to be evil as part of a StealthMentor act.]] In TheMovie, Series/KamenRiderDenO (who's immune to changes in the timeline) demonstrates that the originals can do it too; [[spoiler:later on in the series, Zi-O's actions eliminate the retcon element, meaning that more Legend Riders actually get to help him battle their evil doppelgangers.]]


* In ''Franchise/{{Naruto}}'': the jinchuriki of the Ten-Tails are immune to all ninjutsu, since the Ten-Tails is the progenitor of all chakra, and it's power is virtually the same as the Natural Energy of the world itself. However this also means that Sages, who amplify their techniques with Natural Energy to use senjutsu, are able to harm them.

Added DiffLines:

* The whole premise of ''Film/PacificRim'': "To fight monsters, we created monsters of our own." Or, in other words, the only thing that can kill a horde of colossal {{Kaiju}} (without massive collateral damage) is a legion of equally HumongousMecha.


* In ''Film/CaptainAmericaCivilWar'', Captain America's indestructible Vibranium shield, which previously blocked a blow from Thor's hammer, is scratched by Black Panther because his claws are also made of Vibranium.

** In general, the greatest weaknesses of and the only things that can destroy an Infinity Stone are other Infinity Stones and people empowered by an Infinity Stone. In ''Film/TheAvengers2012'', the fact that Loki's scepter can penetrate the Tesseract's shield hints at both their natures as respectively the Mind and Space Stone. Scarlet Witch highly effective against the same Mind Stone because she received her powers from it to the point that she can [[Film/AvengersInfinityWar destroy it]].

* In ''VideoGame/FireEmblemAwakening'' the last act of the game is spent finding a way to stop Grima, the ''BigBad'' of the game. Your party goes to a shrine to [[BigGood Naga]] in order to perform an awakening ceremony to hopefully give the [[SwordOfPlotAdvancement Falchion]] the power to slay Grima. However, Naga reveals after the ceremony that slaying Grima with the Falchion will only put him into a 1000 year sleep, and only his own power is strong enough to truly slay him

* ''VideoGame/TheWitcher3WildHunt'': Unless a Higher Vampire is finished off by another Higher Vampire, it will regenerate any injury. However, that regeneration can take decades or centuries in case of serious damage, so humans can still ''defeat'' Higher Vampires.



to:

* ''Literature/TheRavenTower'': Gods can only be killed by an attack from another god or by losing all of their power. Of the known [[KillTheGod deicides by humans]], one used a weapon that had been imbued by the victim god to strike its targets dead, and the other starves the god to death by cutting off the HumanSacrifice it needs to fulfill a MagicallyBindingContract it had entered.
