History Main / UnstoppableForceMeetsImmovableObject

->''"Oh, [[ComicBook/{{Batman}} you]]. You just couldn't let me go, could you? This is what happens when an unstoppable force meets an immovable object. You are truly incorruptible, aren't you? Huh? You won't kill me out of some misplaced sense of self-righteousness. And I won't kill you because you're just too much fun. I think you and I are destined to do this forever."''

* Back in the Silver Age, {{Superman}} and Superboy tried to test this out by flying into each other. They wound up with memory loss and ripped the Time Stream a new one.

* Referenced by name in a achievement for ''VideoGame/TownOfSalem'' if a [[IncreasinglyLethalEnemy fully-powered Juggernaut]] attacks a transformed [[NighInvulnerability Pestilence]]. In this scenario, the Juggernaut dies while Pestilence survives. There's also a special message for this scenario (and everybody who sees it gets the achievement due to how rare it is, NOT just the Pestilence and the Juggernaut):

* ''VisualNovel/PhoenixWrightAceAttorney'': Edgeworth tells a story of a weapon merchant presenting gifts to a lord; a spear which can pierce any armor, and a shield which can stop any weapon. The lord immediately pointed out the contradiction, embarrassing the merchant. This story inspired the design for the present day Prosecutor of the Year trophy; a broken shield, and a broken knife. Thematically, it's the equivalent of Ancient Rome's "''[[http://en.wikipedia.org/wiki/Memento_mori memento mori]]''", reminding prosecutors they are not unbeatable.

** The [[ComicBook/IncredibleHulk Hulk]] vs. [[Franchise/{{Superman}} Doomsday]] episode is described as an [[UnstoppableRage unstoppable force]] facing an [[ResurrectiveImmortality immovable object]], respectively. [[spoiler: And in this case, the immovable object Doomsday won.]]

* ''ComicBook/IncredibleHulk'' #272. Hulk and [=Sasquatch=] ram {{Wendigo}} [[http://i47.photobucket.com/albums/f188/A_Flight5/TheIncredibleHulkv2-272-21.jpg using downed trees, with Wendigo in the middle]].

* When former ComicBook/XMen writer Chuck Austen was asked in a interview; what would happen if the unstoppable [[TheJuggernaut Juggernaut]] runs into the immovable Blob? He replied...

* ''Music/{{Skyclad}}'' tells us in "[[BreakupSong You Lost My Memory]]" that:

** Between [[VideoGame/DevilMayCry Dante's]] demonic HealingFactor and VideoGame/{{Bayonetta}}'s physics breaking feats of strength, this fight was labeled as such a clash in the post video. [[spoiler:While Bayonetta was stronger than Dante, she still wasn't strong enough to actually kill him while she's comparatively much frailer than he, giving Dante the win.]]

* This was examined by [=MinutePhysics=] in [[https://www.youtube.com/watch?v=9eKc5kgPVrA this video.]] Their answer? An "immoving" object really refers to an object that is will not accellerate, since the concept of moving depends on the frame of reference of the observer. And an unstoppable "force" refers to an object that is moving, but cannot be accelerated (so they are really the same thing). Although they would require infinite mass, and thus, infinite energy, if these objects ''truly'' could not be accelerated, then [[spoiler:both objects would pass right through each other and continue moving. For an unstoppable force and an immovable object to exist, they must both be intangible.]]

* In ''VisualNovel/FateStayNight: Unlimited Blade Works'' route, Lancer[[labelnote:*]][[Myth/CelticMythology Cu Chulainn]][[/labelnote]] throws Gae Bolg at Archer, who counters by projecting Rho Aias. The scene is called "Lance of Sure Hit, Shield of No Loss." Result: [[spoiler:Rho Aias is pierced, but it took pretty much all of Gae Bolg's power to do that, so Archer survives the remaining impact force.]] In an AlternateUniverse rematch these same two had in ''VideoGame/FateGrandOrder'', Cu Chulainn as a Caster [[{{Deconstruction}} questions the logic behind this trope]], suggesting that if such weapons are as good as they say (an unbreakable shield or an invincible spear), it all boils down to the actual skill of the wielder whether they will win or not.

* Used in the ''Series/KnightRider'' episode "Trust Don't Rust", to describe the theoretical outcome of a head-on collision between KITT and KARR. They refer to it as "Zeno's Paradox".

* In ''VideoGame/WorldOfWarcraft'' there is a Mace called Unstoppable Force and a shield called Immovable Object; both were among the easiest to obtain Epic gear and really good... until the release of the first expansion pack made them next to useless.

** This has actually happened in comics; The Blob's status as "immovable" is more a badass boast on his part than an actual assessment of his powers; while he is ''extremely'' difficult to move, the Juggernaut, the Hulk, and [[ComicBook/XFactor Strong Guy]] have all successfully moved Blob through sheer force. In every case it's been via hitting him so hard that whatever surface he's planted himself on gets broken off from the rest of the ground.[[note]]Blob's power (aside from extreme durability) is a form of gravity manipulation that lets him very firmly attach his feet to whatever he's standing on.[[/note]]

** This also inspired the {{Joke Weapon}}s Stoppable Force and Moveable Object, two pieces of VendorTrash that were useless even when they were first released, except for the little gold they brought.

* ''VideoGame/LeagueOfLegends'': Xin Zhao has a [[EmoteCommand taunt]]: "[[BadassBoast Find me an immovable object, and I'll put this question to rest!]]"

* ''VideoGame/{{Overwatch}}'' has a scenario of this nature. If a [[FoeTossingCharge charging]] [[BoisterousBruiser Reinhardt]] (unstoppable force) meets a [[StoneWall fortified]] [[RobotBuddy Orisa]] (immovable object), the charging Reinhardt will be stopped, meaning the immovable object wins.
** In an unstoppable force vs unstoppable force scenario, if two Reinhardts charge into each other, both will be knocked down and stunned.

* ''Series/TheDefenders2017''. When Series/IronFist punches Series/LukeCage, the result is a KungFuSonicBoom that knocks down everyone in the area, including Luke and Danny.

* According to Creator/GoNagai, ''[[Manga/GetterRobo Shin Getter Robo]]'' is the unstoppable force while Anime/{{Mazinkaiser}} is the immovable object.

** Also, the answer to the question is, at least in VideoGame/SuperRobotWars, '''[[RivalsTeamUp they work together]]'''. Yes, even their counterparts above.

[[spoiler:'''Heck''': [[IWantMyBelovedToBeHappy I want you to be happy.]] More than anything else, I wanted to be the cause of happiness in you. But if I'm not, then I can't stand in the way. Do you see? Because what you're feeling now, [[spoiler:Rachel]], is the unstoppable force... which means that I've got to move.]]

* Given the [[OverNineThousand power levels]] that get slung around in ''TabletopGame/{{Exalted}}'', it usefully has a rule for what happens when a perfect attack comes up against a perfect defense: Defense ''always'' wins.

* In general, quite a few video game bugs can be caused by an object scripted to keep moving along some invisible course hitting some other object that cannot be moved. For example, in early builds of ''VideoGame/TheElderScrollsVSkyrim'' Bees were given collision so that they could be picked up and collide with things, but could not be moved by any amount of outside force. This caused problems with the game's scripted intro (where the player is taken in a cart to be executed) where if a bee randomly flew in/spawned in the path of the cart, the cart (scripted to keep moving until it reached the destination) would hit the unmovable bee, causing the cart to launch itself into the sky.
