* The WebOriginal/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 nuclear 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.

* Since {{Exalted}} contains a lot of 'irresistable' and 'invincible' powers, they do have a rule for this. A perfect defense always wins. ''[[AwesomeButPractical Always.]]''

* ForgottenRealms [[SideStoryBonusArt spin-a-yarn story]] "[[https://ww2.wizards.com/Books/mirrorstone/Article.aspx?doc=fr_spinayarn2004main The Night Tymora Sneezed]]" had a codpiece that "awakens battle-lusts and... lusts in general" and a chastity that "aid [...] in resisting the distractions of the flesh and dedicating themselves wholly to the clear-headed vigilance the Supreme Guardian demands". HilarityEnsues, of course.

* Dungeons and Dragons 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).

* In GreekMythology, Amphitryon once sent an inescapable hound after an uncatchable fox. Zeus's resolution to the paradox was to turn both animals to stone.

* Laelaps & the Teumessian Fox: A fox that can never be caught and a hound that catches everything it chases? That's a paradox [[ClassicalMythology the gods (Zeus)]] could only resolve by turning them both into a constelation.

* In ''PokemonRubyAndSapphire'', it's 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.)
** ''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.)

* The Iron Clefts in ''PaperMario: The Thousand-Year Door'' claim that their bodies can withstand any attack and their spikes can pierce anything. To defeat them, you have to knock them into each other with Yoshi's Gulp attack.

* {{EncyclopediaDramatica}} Longcat vs. Tacgnol.

* {{Uncyclopedia}}: Both MrT and ChuckNorris are depicted as {{Memetic Badass}}es with powers rivaling God. 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 ''PokemonBlackAndWhite'', the version mascots [[PlayingWithFire Reshiram]] and [[ShockAndAwe Zekrom]] are this whenever they meet each other in battle, so much so that [[spoiler:when one uses their signature attack, Cross Flame/Thunder, the other will be forced to respond with a powered up Thunder/Flame. 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.)

* In ''KingdomHearts'', if a heart of pure light and a heart of pure darkness clash, and they are equal in strength, then the most powerful Keyblade, the X-Blade, will be formed. It's only been shown to happen once, with Vanitas and Ven.

-->In this circumstance planetary evacuation may not be sufficient

** On the other hand, when two Pokémon with auto-weather come out at the same time, the slower one's weather stays, so Groudon's sun (which weakens water moves) will likely be in effect in a one-on-one battle between them. This may have been [=GameFreak=]'s attempt at making the fight more balanced, although Kyogre still has the advantage.
** Don't forget SolarBeam, which is a Grass-type move that has its charging requirement negated in sunny weather. Not to mention that both Groudon and Kyogre learn a one-hit knock out move, so in theory the fight fairly matched in moves, if not type.

* In ''PokemonRubyAndSapphire'', it's Groudon (representing the land) vs. Kyogre (the sea). Rayquaza the sky dragon needs to step in to break them up. (Note that this is a case of GameplayAndStorySegregation - when pitting the two against one another in actual gameplay, Kyogre has [[ElementalRockPaperScissors a clear type advantage]].)

* In ''KingdomHearts'', if a heart of pure light and a heart of pure darkness clash, and they are equal in strength, fight, then the most powerful Keyblade, the X-Blade, will be formed. It's only been shown to happen once, with Vanitas and Ven.

-->Since all tests thus far have shown that neither SCP-225-1 nor SCP-225-2 can be damaged or moved by any means known, the possibility also exists that neither object would be annihilated, halted, or altered from their course even by contact with the other. If this is true, then a collision between SCP-225-1 and SCP-225-2 has the potential to [DATA EXPUNGED].

* In ''FateStayNight'', Lancer's ultimate attack uses his cursed spear Gáe Bolg to pierce his opponent's heart without fail ''before he even starts the attack''. In the ''Unlimited Blade Works'' route, he ''throws'' the spear at Archer for even greater power. Archer responds with Rho Aias, a legendary shield that specifically counters spears. [[spoiler:Rho Aias successfully halts Gáe Bolg but is destroyed in the process, consuming a large chunk of Archer's power and shredding one of his arms. Lancer is completely dumbfounded.]]

** Don't forget solarbeam, which is a grass type that is instant in sunny weather, not to mention both of them learn a one hit knock out move, so in theroy it is fairly matched in moves, if not type.

** This also makes it so that the side that wins is dependent upon version (Yin wins in Black, Yang for White.)

** Yin is stronger and defeats Yang.
