History Main / YinYangClash

* Wiki/{{Uncyclopedia}}: Both Creator/MrT and Creator/ChuckNorris are depicted as {{Memetic Badass}}es. According to one article (which has since been deleted or edited into oblivion), the fight between the two of them resulted in the Big Bang and the creation of the universe.

* In ''LightNovel/{{Katanagatari}}'', two of the Twelve Deviant Blades are a sword that is supposedly unbreakable and a sword that supposedly can cut through anything. Shichika briefly wonders what would happen if the swords clashed. Togame guesses that the sword that can cut through anything would defeat the other since it was a later creation of the UltimateBlacksmith who forged all of the Deviant Blades and thus was forged with greater skill and knowledge. [[spoiler:This foreshadows the end of the series, when Shichika, whose fighting style and bloodline are the thirteenth Deviant Blade, easily shatters the "unbreakable" sword.]]
* In ''LightNovel/HighSchoolDXD'', this is the relationship between Boosted Gear and Divine Dividing. Issei's Boosted Gear doubles his power every ten seconds, while Vali's Divine Dividing halves its opponent's power every ten seconds, resulting in a zero sum game. This stalemate is broken the first time when [[spoiler:Issei incorporates a fragment of Divine Dividing into his Boosted Gear armor, by consciously abusing the fact [[AchievementsInIgnorance he doesn't understand how utterly impossible it should be]], giving him an arm that can punch Vali and nullify Divine Dividing's effect]].
* ''LightNovel/ACertainMagicalIndex'': Touma Kamijou's Imagine Breaker ability, housed in his right hand, represents the hope to change the world back to normal. As a result, it is a powerful AntiMagic and PowerNullifier that even works on RealityWarper powers. Kakeru Kamisato's World Rejecter ability, also housed in his right hand and specifically stated to be Imagine Breaker's opposite, represents the hope to escape the current world. As a result, it has the power to create new worlds and exile anyone and anything into them. When the two fight, [[spoiler:Touma's hand gets ripped off and exiled to another world, but the "Invisible Thing" sealed within Touma emerges and injures Kakeru, forcing him to retreat as Touma's hand regenerates.]]

* In ''Series/TheFlash2014'', Captain Cold's freeze ray is designed to project Absolute Zero and Heat Wave's flamethrower is designed to project Klein Temperature or "Absolute Hot". When Flash tricks the two into blasting him at the same time, the blasts cancel each other out and blows everybody back.

* The Wiki/SCPFoundation deconstructs it with [[http://scp-wiki.wikidot.com/scp-225 SCP-225]], a pair of objects, one unstoppable, the other immovable, both indestructible. The Foundation has no idea what would happen if they collided (though a multi-gigaton explosion has been speculated), and they ''really'' don't want to find out. Worse, they have no known way to prevent such a collision if it were going to occur, since neither object can be affected by anything.

* ''VideoGame/FateGrandOrder'': UsefulNotes/SasakiKojiro's sword style is described as an embodiment of "Infinity", as it gives the battle infinite outcomes to give him a 100% chance of victory. UsefulNotes/MiyamotoMusashi's sword style is described as an embodiment of "Zero", as it gives the battle one outcome to give her opponent a 0% chance of victory. When they fight, their clashing swords end up drawing them into a pocket dimension where it is said they would have fought each other for eternity. The stalemate was only broken because Musashi's Master Ritsuka Fujimaru was drawn into the dimension as well, which motivated Musashi enough to win.

* ''WesternAnimation/XiaolinShowdown'': This can occur when two particular [[{{MacGuffin}} Shen Gong Wu]] clash, those being the Two-Ton Tunic, which is a tunic that once activated turns into armor grants the user NighInvulnerability, and the Fist of Tebbigong, which is a PowerFist that grants the user SuperStrength. This match-up actually occurs during an all-out Shen Gong Wu fight between Kimiko and a [[RobotMe robot doppelganger]], where the latter uses the fist to try and punch Kimiko, who uses the tunic to block. [[spoiler:Defense wins here, as Kimiko {{NoSell}}s the punch and actually makes the doppelganger vibrate from the recoil feedback.]]

** ''VideoGame/PokemonRubyAndSapphire'' has Groudon (representing the land) vs. Kyogre (the sea). Rayquaza the sky dragon needs to step in to break them up. (When pitting the two against one another in actual gameplay, Kyogre has [[ElementalRockPaperScissors a clear type advantage]], but Groudon has an ability and movepool that's potentially well-equipped to deal with water-types.)

* In ''LightNovel/HighSchoolDXD'', this is the relationship between Boosted Gear and Divine Dividing. Issei's Boosted Gear doubles his power every ten seconds, while Vali's Divine Dividing halves its opponent's power every ten seconds, resulting in a zero sum game. This stalemate is broken the first time when [[spoiler:Issei incorporates a fragment of Divine Dividing into his Boosted Gear armor, by conscious abusing the fact [[AchievementsInIgnorance he doesn't understand how utterly impossible it should be]], giving him an arm that can punch Vali and nullify Divine Dividing's effect]].

* ''TabletopGame/DungeonsAndDragons'':
** The [[EvilVersusEvil Blood War]] is a conflict between [[OurDemonsAreDifferent the devils and the demons]] to resolve which is the superior force in the multiverse, [[OrderVersusChaos Chaos or Law]]. The demons, representing ChaoticEvil, have a theoretically infinite number of soldiers to call upon and some of those soldiers can be truly formidable individual combatants, but they rarely give consideration to advanced strategies and tactics, and they spend as much time [[WeAreStrugglingTogether fighting amongst themselves as they do trying to bring down the devils]]. The devils, representing LawfulEvil, have well-disciplined, well-trained soldiers and leaders who are ruthless tacticians to make up for the fact that they are frequently outnumbered. Both sides have fought each other to a stalemate for as long as the conflict has gone on.

** ''VideoGame/PokemonBlackAndWhite'' takes this a step further: the version mascots [[PlayingWithFire Reshiram]] and [[ShockAndAwe Zekrom]] are ''literal embodiments of yang and yin''. They are this whenever they meet each other in battle, so much so that [[spoiler:when one uses their signature attack, Fusion Flare/Bolt, the other will be forced to respond with a powered up Bolt/Flare. The faster one will have the weaker attack which is why N's legendary is two levels above yours.]] This also makes it so that the side that wins is dependent upon version (Yang wins in Black, Yin for White.)
*** It reaches the point where, instead of a ThirdOptionAdaptation, Generation V had [[VideoGame/PokemonBlack2AndWhite2 two sequel games]], each of which give version mascot [[AnIcePerson Kyurem]] mutually exclusive forms based on Yin and Yang.
* ''VideoGame/WorldOfWarcraft'' Involves the following player spells, The Warlock's "Chaos Bolt" A spell that's stated to go through everything and anything and in fact, ''does''. Then there is the Paladins "Divine Shield" which is simply put, "You cannot be damaged for the duration of this spell". The result: Chaos Bolt bounces off Divine shield due to the exact nature of the mechanics involved.
** The current version of chaos bolt had this ability removed to make up for the fact that it is now usable every 3 seconds or so.
** ''VideoGame/WarCraftIII'' had the opposite effects when a "Divine" armor type unit takes "Chaos" damage where the damage goes through the armor.

* ''Film/TheMatrix'': Neo vs. Agent Smith.

* The ComicBook/XMen foes Blob and Juggernaut are sometimes portrayed as this. (Juggernaut's superpowers boil down to being an Unstoppable Force, and The Blob's powers boil down to being an Immovable Object.) Though other comics have stated that The Juggernaut would simply win. (Blob is telekinetically bonded to the ground, but the Juggernaut could dislodge him, plus a substantial amount of the ground, as a single unit.)

** The Marvel Comic RPG says that Juggernaut could just force the ground The Blob is on to move and thus beating him. However, they do mention that this method would be moot if they were on a planet of Adamantium (though they didn't state what'd happen then).

* The ''Anime/{{Pokemon}}'' anime, particularly its tie-in movies, uses several version mascot legendary pairs to embody this trope, usually in a manner that puts the setting of the movie where a given legendary pair shows up in severe peril, forcing Ash and another legendary Pokémon to break up the fight before they obliterate a city as collateral damage.

** 3rd edition actually has a lesser known rule that solves this problem if you look at as the "spear/shield" version. In ''D&D'' specific trumps general, and thus the spear that can break any shield (specific power to break shields) trumps the shield that can't be broken (general power to be unbreakable).

* {{Subverted}} in ''Literature/RhythmOfWar''. [[MadScientist Raboniel]] believes that Stormlight (the power of [[GodOfGood Honor]]) and Voidlight (the power of [[GodOfEvil Odium]]) are opposites and if forced to merge would annihilate each other. As it turns out, the two powers are not opposites, and the discovery of the titular Rhythm of War allows the two to be united into a HybridPower called Warlight.

* In ''LightNovel/HighSchoolDxD'', this is the relationship between Boosted Gear and Divine Dividing. Issei's Boosted Gear doubles his power every ten seconds, while Vali's Divine Dividing halves its opponent's power every ten seconds, resulting in a zero sum game. This stalemate is broken the first time when [[spoiler:Issei incorporates a fragment of Divine Dividing into his Boosted Gear armor, by conscious abusing the fact [[AchievementsInIgnorance he doesn't understand how utterly impossible it should be]], giving him an arm that can punch Vali and nullify Divine Dividing's effect]].
