-->-- '''The [[VillainBeatingArtifact Star Rod's]] description''', ''[[VideoGame/KirbysAdventure Kirby's Adventure]]''

Many times, right as TheHero is facing his DarkestHour before TheClimax and final battle, he's rewarded one final gift from fate that gives him the strength to see through his {{quest}}. Exactly how such a thing manifests varies widely: Perhaps it was triggered by ThePowerOfLove or ThePowerOfFriendship (or at least some good old HeroicResolve).

In any case, he has just received the ultimate HeroicSecondWind and resolution of the narrative can't be far off.

Note that where VideoGames are concerned, if the superpower is a new gameplay ability or PowerUp for the character acquiring it, it is often PurposelyOverpowered (i.e., if the player could acquire it earlier, it might prove a GameBreaker) -- ''but'' the game may also regulate or limit its usage to ensure that the player can only use it at its designated time. For example, a plot-oriented FinalBoss may start out as a HopelessBossFight until the player uses the superpower, which cuts the boss down to size for a more fair fight.

Such a power should probably be given a hint of {{Foreshadowing}} earlier on (and hopefully [[ChekhovsGun nothing too obvious]]), otherwise it may feel like a [[DeusExMachina cop-out]]. Also, if the story does ''not'' end soon after the power is introduced, it can turn into a StoryBreakerPower though sometimes players may get access to the power-up after they have beaten the game making it a sort of BraggingRightsReward.

This type of power-up is most likely to fall prey to the BagOfSpilling if a sequel is released, even if the character has access to the other abilities they learned in the previous game this one will be noticeably absent (sometimes with a justification like the power-up being temporary or the character losing access to the item needed for it) though they may be able to regain it again (after a lot of work).

See also the SwordOfPlotAdvancement, which tends to be something more like an "Eighth Hour" superpower (if not earlier).

Contrast SecondHourSuperpower, which is a powerup, item, or skill obtained very early on (often after the first chapter or tutorial) and is a staple (if not keystone) of a character's repertoire.

Also contrast ATasteOfPower, which is basically a "First Hour ''Only''" Superpower, and is subsequently lost. A {{subtrope}} is the LastDiscMagic.

Since this article is obviously about something that happens at the end of the game, spoilers abound below.



[[folder:{{Anime}} and Manga]]
* In the climax of the ''Manga/SoulEater'' anime;, all three meister protagonists get one of these. First, Kid and Blackstar's, whose actually came from later chapters of the manga: [[spoiler:Kid's stripes connecting and Blackstar becoming insanely more powerful after a pep talk with the Will of Nakatsukasa. Except he dies in this version, but whatever. He gets better.]] But notably, Maka, [[spoiler:the last protagonist standing against Asura, who has somehow defeated the other six]] has one ability manifest that is not from the manga: [[spoiler:she's a weapon.]] Whether this is because of [[spoiler:her father being one or the Black Blood she got from Soul]] is not stated. It immediately turns a seemingly hopeless battle over, putting [[spoiler:Asura]] on the defensive for the first and only time in the series.
* ''Anime/TenchiMuyo'':
** In the final episode of the first ''Anime/TenchiMuyoRyoOhki'' OVA, the titular character was able to summon the Light-Hawk Wings (something that normally couldn't be done except by divine trees) to defeat Kagato where no one else could. In a later episode of the extended OVA, he was able to do it once more to rescue two of the girls from a black hole.
** In the animé, Ayeka manages to tap Jurai Energy (an energy that only the royal family can access, but Ayeka never did) to shatter her bonds and send a death wave at Kagato. Unfortunately, Kagato is immune to Jurai Energy and sends the attack back. However, Tenchi then busts out Jurai Energy and combines it with Earth Energy to defeat Kagato with the power of trees, neither of which he had access to because he was still learning the nature of his power.
** In the first movie, when Tenchi's mother realizes who Tenchi is, and thus what she is, she instantly gains access to all of her latent powers and kicks the BigBad's ass long enough for everybody to escape. [[spoiler:WordOfGod states this attack weakened her, and it's why she died so young.]]
** In the second movie, when Tenchi is trapped in the dark world and unable to access his light-based powers. Ayeka uses a branch from her brother's tree-ship to project herself (and a source of light) into the dark world, granting Tenchi the ability to use his standard light-powered sword-based badassery. This functions as a double case as both Ayeka used a never-before seen power, and catapulted Tenchi to new levels of power.
* Right before the final battle in ''Anime/MagicalGirlLyricalNanohaAs'', Chrono receives the Durandal, a powerful [[MagicWand Storage Device]] that was able to freeze a huge, bio-mechanical EldritchAbomination along with a large chunk of the sea surrounding it.
%%* ''Manga/MermaidMelodyPichiPichiPitch'': KODOU (which in the second season was [[SoLastSeason reduced]] to a practically first-level song) and Kibou no Kaneoto -Love goes on-.
%%* In ''Manga/KamichamaKarin'', Micchi's mysterious [[TransformationTrinket transformation ring]] isn't activated until towards the end of the final battle.
* ''Anime/DigimonAdventure'': Almost every BigBad was defeated this way -- Devimon through Takeru and Patamon learning to evolve at literally the last second, Etemon through Taichi and Agumon activating his crest for the first time, Vamdemon through Hikari and Tailmon finishing becoming {{Sixth Ranger}}s and [[BackFromTheDead again]] through two of the protagonists learning to reach the Ultimate level, and Piemon through Takeru and Patamon (again) activating his crest for the first time; the last being the straightest example in that it took place at the climax of the third-last episode. This does tend to be something of a recurring tendency across the franchise as a whole in how new evolutions are obtained -- at practically the last second when fighting a powerful enemy. As the series went by, when dealing with a BigBad it only happened once or so per series and restricted themselves to dealing with the actual biggest BigBad; these being [[Anime/DigimonTamers Dukemon Crimson Mode]], [[Anime/DigimonFrontier Susanoomon]], [[Anime/DigimonSavers ShineGreymon Burst Mode]] and [[Anime/DigimonXrosWars Shoutmon X7 Superior Mode]].
%%* The ''Anime/DigimonTamers'' movie Battle of Adventurers did this with the [[CombinedEnergyAttack Trinity Burst.]]
* In ''Manga/JoJosBizarreAdventure'', every main villain gets access to one of these before the final battle except in parts 3 and 5 where it's the hero instead:
** In Part 1, Dio becomes able to shoot pseudo-EyeBeams at the very end of his penultimate fight with Jonathon, which plays a bigger role in the final battle as it allows Dio to attack Jonathon even after [[OffWithHisHead being reduced to a severed head]].
** The second part has Kars using the Stone Mask combined with the Red Stone of Aja to become [[UltimateLifeForm Ultimate Kars]].
** The third part features Star Platinum, Kujo Jotaro's Stand, who has a very short range, so it should be very powerful... but he only seems to have an outstanding speed, great strength, and surprising sight and precision. [[spoiler:On the last fight against Dio, [[TimeStandsStill the stand-using vampire who can stop time]], it's revealed that the apparent super speed of Star Platinum was in fact ''its own ability to briefly stop time''. Epic ensues.]]
** In Part 4, the final arc, [[Music/{{Queen}} "Another One Bites The Dust"]] is kicked off when [[spoiler:the Stand-granting Arrow pierces the BigBad, Kira Yoshikage, granting him a second Stand ability, Killer Queen Bites The Dust. This ability transforms a person of his choice into [[ActionBomb a living bomb.]] If this person tells anyone about Kira's true identity, or if he's even questioned about the matter, Bites The Dust will immediately blow up everyone present who learned the identity. [[GroundhogDayLoop It then rewinds time by an hour.]] In this new timeline, the target will inevitably explode again, even if he doesn't talk to Bites the Dust's host again. It is described as an absolutely foolproof way for Kira to protect his identity, since it makes inquiring the host about it impossible, and since it then resets to a timeline where the inquiry didn't even happen, the host can't be traced to Kira either.]]
** In Part 5, Giorno's Stand Gold Experience evolves into Gold Experience Requiem when fighting Diavolo, allowing him to nullify the latter's King Crimson and place him in a never-ending death loop. [[JustifiedTrope Justified]] due to the use of the Stand Arrow.
** In Part 6, Pucci's Stand Whitesnake goes through one transformation earlier on into [[GravityMaster C-Moon]] [[spoiler: and then again before the finale into [[TimeManipulation Made In Heaven]] which at its peak basically has a limitless version of Star Platinum: The World's time-stopping ability]].
** Part 7 has Funny Valentine [[spoiler: combining his already overpowered Stand Dirty Deeds Done Dirt Cheap with Lucy Steel's Stand's ability to redirect misfortune, creating [=D4C=] Love Train.]]
* ''Anime/DragonBallZ'': Super Saiyans, firstly done by Goku in order to beat Freeza, and the other is pulled by Gohan in order to beat Cell. Both involve the bad guys doing something to trigger the heroes' ultimate anger. Both of these incidents début real SSJ 1 and 2 into the main series. While the first level of the Super Saiyan transformation becomes invokable by will, the Saiyans are always striving for bigger and badder iterations.
** ''Anime/DragonBallSuper'' continues the tradition, especially during the long Universe Survival arc, where both the known heroes and new opponents get in on the action almost every second episode. Goku alone uncontrollably enters the new "Ultra Instinct" form, which scares even the Gods who have yet to master the ability, 3 times when pushed against an insurmountable wall. Other examples include Vegeta's new "Super Saiyan God SS Shinka" form, Universe 11's Toppo's ascension to God of Destruction, and Universe 2's Ribrianne's "Super Ribrianne" form. Just to name a few.
* In the animé version of ''Manga/YuYuHakusho'', Yusuke, after recovering from a mid-battle HeroicBSOD against Yomi and regaining a purpose in life, temporarily achieves [[spoiler:Sacred Energy]], which provides enough of a power boost to fight one of the most powerful demons alive to a near draw, Yomi only winning by passing out mere seconds after Yusuke.
%%* Cosmo in ''Anime/SonicX'' turned into a tree during the final battle with Dark Oak (granted, this did ultimately cause her death and is supposed to be a general thing for her species -- her growth spurt was just sped up a bit by a magical amulet).
* The Miracle Lights in ''Anime/PrettyCureAllStars'' act like this, granting the gathered teams their Super forms to flatten that movie's BigBad.
** All of the ''Franchise/PrettyCure'' movies do this, actually. The Miracle Lights were mostly only for the two ''Yes!'' movies (though they somehow show up in ''Heartcatch'''s), but all movies use AudienceParticipation plus a random item to bring out super modes.
* ''LightNovel/InfiniteStratos'':
** During his first battle, Ichika's Byakushiki achieves First Shift, which essentially means [[EvolvingWeapon the suit customized itself to him by reading his combat style]]. In the final episode, Ichika has EpiphanyTherapy and the Byakushiki [[EmpathicWeapon undergoes Second Shift]], becoming Byakushiki Setsura just prior to entering the fray. Compared to its original form, the suit loses its CripplingOverspecialization for mélee combat by supplementing [[{{BFS}} Reiryaku Byakuya]] with a ranged attack and DeflectorShields.
** Similarly, Houki was the most combat-ineffective character in the show due to not having a personal IS... until three episodes from the end, when she got the [[SuperPrototype Akatsubaki]]. [[spoiler:[[{{Cloudcuckoolander}} Tabane]]]] didn't lie when she said it was powerful -- that suit is a textbook example of a LightningBruiser.
* ''Anime/GaoGaiGar'' has ''THE POWER'', a form of energy native to Jupiter with [[GreenRocks ill-defined properties]]. It's introduced a few episodes before, but the heroes use it during the final battle with [[BigBad the Primevals]] to defeat them for good. [[spoiler:Unfortunately, one of the Primevals decided to do the same, and used [[OneWingedAngel the villainous equivalent of this trope]] and ''THE POWER'' to become the planet-sized Z-Master.]]
* During ''[=GaoGaiGar FINAL=]'', [[spoiler:the heroes bring out the [[DropTheHammer Goldion Crusher]], designed in the wake of the Z-Master to deal with enemies of that scale. They use it to [[DisappearsIntoLight crush]] Pisa Sol, an artificial evil sun that's been regenerating the other villains.]]
* ''Anime/PuellaMagiMadokaMagica'' [[DeconstructedTrope deconstructs this trope.]] Following the arrival of [[EldritchAbomination Walpurgisnacht]], Madoka's hand is forced and she agrees to become a MagicalGirl in order to save the day. It's too bad this is [[spoiler: AllAccordingToPlan and will lead to Madoka's destruction ([[WhatMeasureIsANonCute and also the destruction of the entire world]]). Homura continues to [[GroundhogDayLoop turn back time]] until she can keep her friend from powering up in order to save her life ([[MyFriendsAndZoidberg and the planet]])]].
%%* {{Deconstructed|Trope}} in Anime/PuellaMagiMadokaMagicaTheMovieRebellion. Homura gets a ThePowerOfLove power-up and [[spoiler: basically god powers at the end. She uses them to render Madokami (who came to take Homura to Magical girls Valhalla) powerless, trap her in Homura's rewritten universe as a normal schoolgirl and force the whole race of Incubators into being her slaves.]]
%%* The first season of ''Anime/MobileSuitGundam00'' features this in the form of the [[LawOfChromaticSuperiority Trans-Am system]], introduced in Episode 22.[[spoiler: Even with this new-found power Celestial Being still suffers many losses in the following final three episodes of the season.]]
* Haruka of ''Manga/KotouraSan'' reads the minds of everyone around her [[PowerIncontinence whether she wants to or not]], but she can't transmit her own thoughts to people. Until episode 11, that is, when she manages to telepathically call for Manabe's help while [[spoiler:the criminal who had been attacking high schoolers is trying to kill her]].
* The ''Manga/{{Naruto}}'' movies are big fans of this trope, as Naruto combines his Rasengan with some other form of power through unexplained or convoluted means to create a brand new version of the Rasengan to defeat the film's BigBad.
** Kakashi gets one ''in spades'' when [[spoiler:the recently-deceased Obito infuses his spirit in Kakashi, giving him not only both of Obito's Sharingan eyes, but the ability to use ''the perfect Susano'o,'' if only for a short period of time.]]
** Naruto's Tailed Beast Mode is a complex example of this. He gains it late in the war after being confronted with 5 tailed beasts and uses it to defeat Obito. [[spoiler:However, Naruto loses it when Kurama is extracted from him by Madara. When Naruto is revived, the infusion of Kurama's other half plus half of Hagoromo's chakra and part of all the tailed beasts changes it into Six Paths Sage Mode, a similar, but much more powerful form. Eventually, as Naruto regains both halves of Kurama, the form is reverted to a variant of its initial appearance a couple years down the line.]]
* ''Anime/{{Pokemon}}'': The Diamond and Pearl series had a lot of these. During the Sinnoh League, not only did Ash's Infernape learn Flare Blitz in the episode before Ash's battle with Paul started, but several of his older Pokémon made return appearances with new moves. Ash's Gliscor also returned with Stone Edge now in its move set. Played with in the Unova League, since Best Wishes continued on after it, but a few of Ash's Pokémon had new moves for the league. In fact, Ash himself did this on purpose by teaching his Krookodile Aerial Ace right before his battle with Stefan to keep the element of surprise.

[[folder:Comic Books]]
* In one of the last story arcs of ComicBook/{{Etrigan}}'s title, Hell is being invaded by forces led by a powerful angel of war, who is tearing through Etrigan and his demons with ease. Etrigan eventually defeats him by finding a crown embodied with all the power of Hell and curbstomps him.
* In the DC ''ComicBook/OurWorldsAtWar'' event, Superman temporarily merges with Kismet, the living embodiment of the universe, to help defeat Imperiex. Later he gains enough power by flying into the sun to stop War World.
* During Marvel's ComicBook/ChaosWar event, Thor is fighting an eldritch abomination named Glory, and losing, but manages to pull out the strength to win via a powerup from a woman who was praying to him.
* TheHulk's "Worldbreaker" form basically counts as this.
* In ''ComicBook/{{Violine}}'', Violine is revealed to be able to communicate psychically with her pet mouse. This is foreshadowed when her and her father read each other's minds without looking each other in the eyes (which is normally required to read other people's thoughts).

[[folder:Fan Fiction]]
* In ''Fanfic/APonyOutOfPlace'', [[spoiler:Flare Blitz, a Ponyta, evolves into a Rapidash during an important race, giving him a speed boost and access to unicorn magic, which comes in handy during his battle with Arceus.]]
* ''Fanfic/ChildOfTheStorm'' has Jean Grey discover her full power in chapter 75, after Strange bluntly informs her of it.
** Carol Danvers wields the GreenLanternRing of Alan Scott in chapter 76 through the finale and [[spoiler: Diana]] picks up Mjolnir.
** At the end of the ''Forever Red'' arc, in the sequel, [[spoiler: Maddie]] seals her HeelFaceTurn by lifting Mjolnir... leading to the LemonyNarrator lamenting that the universe does ''not'' have a soundtrack, and therefore this ''isn't'' accompanied by a rendition of AC/DC's ''Thunderstruck''.
* ''The entire cast'' of ''FanFic/LatiasJourney'' at the end of the last battle.
* [[http://www.fanfiction.net/s/7623289/1/ Transcendence: Digital Curse]]. After spending most of the story cursed by the Chronodata and unable to digivolve, Agumon is finally able to use it to digivolve and fight off the unstoppably powerful Abyssgreymon in the climax.
* In addition to [[Franchise/SuperMarioBros Mario]] getting his required Eleventh Hour Superpower ({{crossover}} with the ''VideoGame/PaperMario'' series, after all), all of the non-Mario characters in the ''FanFic/PaperMarioX'' series also gain Eleventh Hour Superpowers:
** [[Franchise/TheLegendOfZelda Link]] gains the Master Sword, Malon and Zelda gain Light Arrows, and Ganondorf can turn into Ganon.
** [[Franchise/SonicTheHedgehog Eggman]]'s machine gets upgraded and everyone else turns {{Super|Mode}}.
** Franchise/{{Kirby}} gains the Dragoon Rider and the Star Rod while Meta Knight gains Master.
** [[Franchise/{{Metroid}} Samus]] can use her Zero Laser.
* {{VideoGame/Sonic|Generations}} turns into [[SuperMode Super Sonic]] during the FinalBoss fight of ''[[FanFic/SonicGenerationsFriendshipIsTimeless Sonic Generations: Friendship is Timeless]]'', of course, but [[WesternAnimation/MyLittlePonyFriendshipIsMagic the Mane 6]] also [[http://fav.me/d5c1yv7 gain]] [[http://fav.me/d4rffbx Super]] [[http://fav.me/d5ayw0i forms]] [[http://fav.me/d5bh6mm of]] [[http://fav.me/d5a1hbm their]] [[http://fav.me/d5adywz own]].
* In ''Fanfic/PokemonTheGreatAdventure'', before they awoke, As's latent Aura Powers had the habit to kick in and take him out of a tight spot ... such as being cornered by a pack of angry Mankey.
* In ''FanFic/{{Revelations}}'', Túrante gets a new power in chapter 29, just in time to save her allies. She uses the power to destroy some enemies and summon TheCavalry.
* The ''FanFic/PonyPOVSeries'' has an example during the FinalBattle of the Wedding Arc: [[spoiler: during the duel between Cadence and [[EvilTwin Queen Cadenza]]/[[AGodAmI Alicorn!Chrysalis]], Chrysalis lets slip that alicorns have the abilities of ''all'' the tribes of ponies, ''including'' changeling VoluntaryShapeshifting. As such, Cadence is able to tap into this, beginning a ShapeshifterShowdown]].
* The ''FanFic/FacingTheFutureSeries'' gives us a new ghost form that gives Danny a massive power boost. However, it has two side effects as Danny not only loses control of his rage, but the energy generated by his new form could cause his form to burn out.
* ''FanFic/ShadowsAwakening'': Uncle creates a chi sword for Jackie (which works similarly to Daolon Wong's Dark Chi Warriors' weapons) for the penultimate fight in the Forge of Shadows. In the next chapter (the FinalBattle), Viper also gets a chi spear.

[[folder:Films -- Animated]]
* In ''Disney/{{Tangled}}'', it's revealed at the climax that Rapunzel's tears share the same regenerative power as her hair.
* In ''WesternAnimation/TheIncredibles'', baby Jack-Jack is thought to not possess any superpowers, but when the BigBad kidnaps him in the final climax, he is revealed to have ''many'', including bursting into flame, becoming metal, turning into a super-strong demon, and more. The only foreshadowing is a series of increasingly panicked voicemails his mother gets from the babysitter (with context later provided in the short film ''Jack-Jack Attack'').
* At the climax of ''WesternAnimation/KungFuPanda2'', Po finally attains inner peace, which [[RuleOfCool somehow]] extends from being able to redirect water drops on leaves to being able to redirect ''cannonfire'', allowing him to destroy the {{Big Bad}}'s fleet.
* In ''WesternAnimation/TheSpongeBobMovieSpongeOutOfWater'', the protagonists gain their superhero alter-egos in the last 20 minutes of the film. For a 13th hour example, [[spoiler:when Spongebob uses the book to press the ResetButton, he adds a slight caveat that gives Squidward the HeroicBuild]].
* During the climax of ''WesternAnimation/HowToTrainYourDragon2'', Toothless [[TuckAndCover protects]] Hiccup from a point blank shot of ice breath from Drago's Bewilderbeast and after a few harrowing moments pass, he erupts from the ice with his back scales/fins glowing blue and his breath attacks greatly amplified in force and speed. As he didn't get to do more aside from launching a barrage of these amplified plasma blasts during the film itself, any other effects of the power up are unknown.
* In ''WesternAnimation/ABugsLife'', Dot has been having trouble being able to fly, but when she goes to find Flik and the circus bugs to get them back to the colony, [[DieOrFly she's able to do so]] ("Come on, wings. Fly, fly!") and reach them in time.
* In ''WesternAnimation/TheTransformersTheMovie'', Hot Rod is being strangled by Galvatron in the final battle of the movie. Fortunately, this puts the Matrix of Leadership hanging around Galvatron's neck within reach. Hot Rod grabs the Matrix and wrests it free, and the Matrix (along with the spirit of Optimus Prime) deems him worthy of becoming the Autobots' leader. The power of the Matrix transforms Hot Rod into Rodimus Prime. Rodimus' increased strength and size allows him to easily defeat Galvatron and throw him into space.

[[folder:Films -- Live-Action]]
* ''Film/CaptainAmericaCivilWar'': When things start getting desperate for Cap's team, [[spoiler:Ant-Man uses his Pym Particles to grow to giant size and start stomping people]].
-->'''Iron Man:''' Ok, anybody on our side hiding any shocking, fantastic abilities they'd like to disclose?! I am open to suggestions!
* In ''Series/KamenRiderDouble [[TheMovie Forever]]'', Double is getting his butt kicked by [[BigBad Kamen Rider Eternal]] when the people of the city start calling out to him, [[ClapYourHandsIfYouBelieve imbuing his normal Super Mode with the power of their hopes]], turning Double [[PowerGlows gold]] and [[PowerGivesYouWings giving him wings]].
* In ''Film/SpaceJam'', UsefulNotes/MichaelJordan, despite playing like a regular basketball player most of the movie, suddenly develops, ironically, a WesternAnimation/LooneyTunes style body at the final seconds of the BigGame. This is right after he witnesses his human friend Stan Podolak get flattened like a pancake and subsequently inflated like a balloon. A twist on the trope in that Michael could have done that at ''any'' time, he just didn't ''know'' that until the game was almost over (and he even calls the Tunes out on not telling him earlier).
* In ''Film/SkyHigh2005'', the protagonist Will Stronghold unlocks the ability to fly that he inherited from his mom, [[DieOrFly after getting thrown through the window]] by the BigBad.
* In ''Film/WonderWoman2017, the titular character gains her power to vanquish Ares just before the end.
* Bruce Leeroy mastering the Glow at the end of The Last Dragon
* In ''Film/KungFuHustle'', Sing's chi flow is cleared after he is nearly beaten to death by the Beast. This unlocks his true potential as a kung fu master.

* The Deathly Hallows in Literature/HarryPotterAndTheDeathlyHallows. The hallows are a trio of relics that are not mentioned until halfway through the last book. The final battle hinges on their existence. However, this is still a downplayed example. Harry has possessed one of the three hallows since the first book: the cloak of invisibility. Meanwhile, the ring (another one of the Hallows) was revealed relatively early in the sixth book. And the power given by the Hallows ([[spoiler: the ability to accept death]]), while essential to Harry's triumph, is not used directly against Voldemort.
* In the last book of ''Literature/GalaxyOfFear'', it is revealed that like his sister Tash, Zak is Force-Sensitive. Which is odd, because it's well established that for her entire life, Tash has been a little strange and [[PsychicChildren psychic]]. She's been having her undeveloped [[MySignificanceSenseIsTingling Force senses]] go off often as the kids have been in danger, a Force-ghost seeing both of them said he could [[InvisibleToNormals only be perceived by a Force-Sensitive]], and she's explicitly able to tell if she meets someone who can use the Force. Zak's never been shown with any of that.
* ''Literature/LegacyOfTheDragokin'': In the final act of the climax, Benji awakens his latent dragokin powers.

* The ''Series/DoctorWho'' episode "The Eleventh Hour" plays it almost literally has the 11th Doctor programming a zero reset out of nowhere. The Doctor has not shown (at least recently) that ability to program beforehand.
* The GrandFinale of ''Series/EarthFinalConflict'' has the heroes [[StormingTheCastle storming the Atavus ship]] that was recently discovered, which is full of thousands of Atavus warriors in [[HumanPopsicle stasis]]. Suddenly, Hubble Urick brings them a dozen energy {{Hand Cannon}}s capable of killing an Atavus with one shot. Prior to that, only Renée's energy pistol could do that, and it took several shots, with normal guns having no effect. However, those are clearly prototypes, so they may not have been available before.
* Eddie gets one in ''Series/HouseOfAnubis'', unlocking his Osirian powers at the end of season 2, which was the first time he had needed to use them.
* ''Series/KamenRiderDrive'': [[spoiler: After Chase dies to Banno's Gold Drive, Gou uses his left behind Signal Bike in order to create Chaser Mach, a fusion between Mach and Chaser that easily lays the smackdown Banno.]]
* ''Franchise/SuperSentai'':
** ''Series/ResshaSentaiToQger'' takes this trope to the [[UpToEleven absolute extreme]], as [[spoiler:[=ToQ=] #1 Rainbow is obtained ''during'' the final battle.]]
** ''Series/ShurikenSentaiNinninger'' inversely pulls this back a bit. [[spoiler: Super [=StarNinger=] is obtained in Episode 36, which is within the final fourth of the series.]]
* ''Series/StrangerThings'': In the first season, Eleven finally used her powers of telekinesis to the greatest effect when she desintegrated the Demogorgon - though it isn't exactly her tapping into hitherto unknown sources. In season 2, however, she gains [[spoiler: the ability to fuel her power while channeling her rage, thus being enabled to close the gate between the dimensions.]]

* ''Roleplay/DestroyTheGodmodder'': Several, near the end of several arcs, players gained extra powers, making them significantly stronger, notably in the final fight of the first game, where almost everyone got them, twinbuilder used his recently gained reality-warping Fez to great effect.

* In [[UsefulNotes/AmericanFootball American Football]], the "Two-minute drive" MiracleRally can appear to be this if a team that has been largely ineffective on offense turns the intensity UpToEleven at the closing minutes of the game and scores a touchdown to win the game. This phase of the game relies much more on high-risk / high-reward plays that are often spectacular to the spectators regardless of outcome.

[[folder:Tabletop Games]]
* ''TabletopGame/{{Exalted}}'' during ''Return of the Scarlet Empress'', the Five Maidens will unlock the highest tier of Sidereal Charms if things get dire enough. Considering that the Ebon Dragon is marching his army to Heaven, things are indeed dire enough.
* The Talent Unlock Burst mechanic in ''PsionicsTheNextStageInHumanEvolution'' can result in this. In addition to overflow, it is possible, if rare, for intense negative emotions to grant an esper a large amount of caps, which can result in a new level of psitalents being unlocked, temporarily or permanently, and a number of powerpoints being automatically restored. The example given in the book details a restrained telekinetic spontaneously developing necrokinesis in response to their girlfriend's life being threatened.
* The ''TabletopGame/{{Pokemon}}'' TCG has an attack titled "11th Hour Tackle". It does 50 damage unless there are three cards or fewer left to draw, in which case it does 180.

[[folder:Video Games]]
* The Dark Energy Gravity Gun in ''VideoGame/HalfLife2'' that appears in the penultimate level. Different only in that it's available for the last several levels instead of merely the final boss fight. It's also [[FisticuffsBoss the only weapon you can use for these sections]], requiring a bit of extra work; its range is still limited, but since it was rather good to begin with, and it now causes ''instant death'' of a bone-breaking, muscle-dislocating nature in all humanoid enemies (the only kind you'll face until the strider halfway through and the two gunships at the ''very'' end) and can [[ShutUpHannibal rip bolted-down wall monitors with Breen on them ranting at you off the wall with a simple yank]], this hardly matters. It is also very, ''[[VideogameCrueltyPotential very]]'' fun.
** Since Word of God says we won't ever see the Dark Energy Gravity Gun again, ''Episode Two'' gave us the Magnusson Device, which is an instant kill if mounted on a Strider and detonated.
* In ''VideoGame/{{Resistance}} 2'', Hale defeats the BigBad and absorbs his psychic powers, which reduce chimeras to [[LudicrousGibs chunky salsa]]. After a brief rampage, however, it turns out it wasn't probably wasn't [[WithGreatPowerComesGreatInsanity for the best.]]
* The [[SequentialBoss very-definitely-final boss]] of ''VideoGame/ParasiteEve'' is impervious to everything you use on it -- bullets, rockets, shotguns, ultimate techniques... and then the main character is given bullets laced with [[AppliedPhlebotinum her own DNA,]] lethal to the creature's own cellular structure. The resumed boss fight takes less than a minute to complete.
** Well, very nearly impervious. The boss still takes 1HP damage from every attack, so in theory it can be beaten. But, considering that the boss has about 3000 HP, and that the number of bullets/ordnance you can carry is limited, AND it can one-hit kill you...just use the damn special bullets.
* Most of the ''Franchise/SonicTheHedgehog'' games from ''[[VideoGame/Sonic3AndKnuckles Sonic and Knuckles]]'' on end with a boss fight in SuperMode, though the ability was unlockable in normal gameplay as well up until ''VideoGame/SonicAdventure'', at which point it became a true Eleventh Hour Superpower.
** ''[[VideoGame/SonicStorybookSeries Sonic and the Secret Rings]]'' and ''[[VideoGame/SonicStorybookSeries Sonic and the Black Knight]]'' did things slightly differently, giving you Darkspine Sonic and Excalibur-Sonic, respectively.
** Averted in the Wii and Wii U versions of ''VideoGame/SonicColors'' and ''VideoGame/SonicLostWorld'' respectively, where both the Nega-Wisp Armor and the Eggrobo are fought as normal Sonic and Super Sonic is once again unlockable for normal gameplay.
*** Played straight in the DS version of ''Colors'', however. Collecting all the Chaos Emeralds just unlocks the TrueFinalBoss, the Nega-Mother Wisp, which is once again a standard "use Super Sonic in space" level. However, unlike the Wii version, Super Sonic doesn't carry over to the regular levels.
** ''[[VideoGame/SonicGenerations Generations]]'' has the final boss as both Super Sonics, and after that they are unlocked for use in normal stages, as an equippable skill that can only be used on its own.
* ''VideoGame/SummonNight: Swordcraft Story'' and ''Summon Night: Swordcraft Story 2'' gives you the ultimate weapon before fighting the final boss.
* Franchise/SlyCooper gains the ability to walk on laser beams mere moments before the final boss fight in ''VideoGame/Sly3HonorAmongThieves''.
* ''Franchise/TheLegendOfZelda'':
** The Silver Arrows, or their {{expy}} the Light Arrows, in several of the ''Zelda'' games (but not in every appearance). In ''VideoGame/TheLegendOfZeldaTheWindWaker'', the Light Arrows are a one-shot kill on almost everything. In''VideoGame/TheLegendOfZeldaALinkBetweenWorlds'', you only have them halfway through the FinalBoss battle.
** Specifically in ''VideoGame/TheLegendOfZeldaMajorasMask'', the ludicrously powerful Fierce Deity's Mask, although you had to [[HundredPercentCompletion meet certain conditions first]].
** There's the giant mask that's only usable in one boss room in the entire game.
** In ''VideoGame/TheLegendOfZeldaPhantomHourglass'', Link's fairy companion randomly and without warning pulls the ability to stop time from nowhere in the first part of the Final Boss Fight. This continues on to the second and third rounds, as well.
** The original ''[[VideoGame/TheLegendOfZeldaI The Legend of Zelda]]'' has the Red Ring, which quadruples your defense, but is unavailable until the last dungeon. Even worse in the second quest where the Red Ring is located only a few rooms away from Ganon.
** The final Great Fairy in ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' doubles your defense, but can only be reached using the Golden Gauntlets, which are found in the last dungeon.
** In ''VideoGame/TheLegendOfZeldaLinksAwakening'', Link doesn't get access to the Fire Rod, a ranged attack that can one-shot most enemies (including [[KillerRabbit chickens]]), until the penultimate dungeon.
** In ''VideoGame/TheLegendOfZeldaBreathOfTheWild'', Link gets the Bow of Light during the fight against Dark Beast Ganon, and has to use it to [[AttackItsWeakPoint shoot at Ganon's weak points]] [[MountedCombat while on horseback]].
* Doing the fusion with Nemesis for the fight against Apocalypse in ''VideoGame/{{Silver}}''.
* ''VideoGame/DevilMayCry'':
** Dante's Sparda Devil Trigger in the first game.
** To a lesser extent, the "Dark Slayer" Style in ''VideoGame/DevilMayCry 4'', gained at the start of Dante's last mission. However, it is balanced against Dante's other styles, and isn't nearly as overpowered as most other examples.
** The NewGamePlus element of the game results in you being able to permanently use it in all following playthroughs. Dark Slayer Style is actually an example of an ability that was obviously designed to be used with New Game Plus, as it is not particularly useful against Dante's final boss.
* In ''VideoGame/RuneFactory2'', when you are near the end of the second generation, you gain a spellbook called "Dragon Break." This spellbook is only useful against the Final Boss. But, using it makes the final battle a CurbStompBattle in your favor.
* In ''[[VideoGame/SoulSeries Soul Calibur]]'', Xianghua's mother's keepsake revealed itself to be the titular sword, which Xianghua would use to defeat Inferno. GameplayAndStorySegregation turns it into a subversion, as it isn't any better in battle than the Krita-Yuga was.
* In the final battle of ''VideoGame/{{Gungrave}}: Overdose'', your character is filled with so much [[UnstoppableRage rage]] that his appearance changes slightly (Beyond the Grave's eye glows completely white and his hair goes [[Anime/DragonBallZ super-saiyan]]-ish, Rocketbilly suddenly becomes [[ShirtlessScene shirtless]], and Jyuji wears Bunji's shades and the flame on his back turns blue). The demolition shot gauge then begins to regenerate and fill up on its own, which lets you use your D. Shots more frequently.
* Happens to an extent in ''VideoGame/KnightsOfTheOldRepublic II'', when [[spoiler:after Kreia kills the Jedi Masters or talks to you after you kill them]], you magically get either the dark side uberpower Force Crush or the Light Side uberpower Force Enlightenment, both of which are probably the best power for their respective alignments.
* Throughout ''VideoGame/LittleNemoTheDreamMaster'', your only weapons are thrown candy, which does no more than stun enemies, and whatever abilities are granted by the animals you charm. In the last level, Nightmare Land, however, you are given the Royal Scepter, which fires actual damaging projectiles, although it has a lengthy charge-up perioid and only fires at a diagonally upward angle, only making it useful on the last few bosses.
* ''VideoGame/{{Onimusha}} '':
** The powers granted by the five orbs in ''VideoGame/{{Onimusha}} 2'', resulting in an UnexpectedGameplayChange into a [[spoiler:third person shooter via turning the main character into a demonic equivalent of VideoGame/MegaMan.]]
** In ''Dawn of Dreams'', for one part of the final boss fight, Soki is given the Oni Gauntlet (which holds the soul ''and'' power of Nobunaga Oda), allowing him to transform into a huge, heavily-armored ogre warrior. He can fly and use both of his swords at once, as well as getting a new skill called "Ultimate Critical".
** In the original game, if you've completed a very difficult side-quest, you'll later be rewarded with the Bishamon Sword. Its basic attack deals more damage than anything in your arsenal...save its ''magic'' attack, which can be used infinitely. You get to use it for all of one room before reaching the final boss.
* For the final level in ''VideoGame/PrinceOfPersiaTheSandsOfTime'', your awesome time-controlling dagger gets taken away, but you're given a sword that one-hit-kills any of the sand monsters, so fights generally go really fast. Then the sword gets taken away and the dagger is given back for the FinalBoss fight (although the boss was human, so the sword probably wouldn't have worked on him anyway).
* ''Franchise/ResidentEvil'':
** In the original ''VideoGame/ResidentEvil'', ''VideoGame/ResidentEvil2'', and ''VideoGame/ResidentEvil4'', you are thrown a rocket launcher with which you take out the final boss in the game. Meanwhile, ''VideoGame/ResidentEvil3Nemesis'' ends with the player coincidentally finding the big boss in the same room as a giant stationary rail gun.
** In ''4'', you CAN beat Saddler without the rocket launcher, though this is VERY difficult and a lot less fun. There are also less powerful rocket launchers available throughout the game, which ''will'' kill every other boss with one shot.
** This trope is basically in every game. Including the Linear Launcher in ''VideoGame/ResidentEvilCodeVeronica''.
** While it wasn't used on the final boss, the {{Kill Sat}} from ''VideoGame/ResidentEvil5'' deserves a mention (imagine facing zombies with THAT).
** Or super heroes in ''VideoGame/MarvelVsCapcom3''.
** In ''Videogame/ResidentEvil6'', at the end of Chris's campaign, [[spoiler: Piers gets an actual superpower. His EmergencyTransformation via C-Virus gives him HealingFactor and a LightningGun for an arm, but as it starts to affect his mind, he chooses to sacrifice himself in a supercharged attack that kills both him and the final boss]]. Also, Leon traditionally gets a rocket launcher to finish his final boss, and Ada steals a helicopter that makes her last level a lot more fun. Inverted with Jake, who [[spoiler: gets in a FisticuffsBoss fight with Ustanak]].
* ''VideoGame/PlanescapeTorment''
** The powerful "Symbol of Torment" is not available until the very final scenes of the game. Given the many ways available to deal with the final boss [[SkippableBoss without fighting him]], chances are good it never sees any use.
** One of the Nameless One's normal abilities acquired at the beginning of the game is the ability to raise people from the dead, albeit with a lot of limitations. It doesn't come out until the very end that [[spoiler:he can raise anyone from the dead. At will. Without cost.]]
* ''Franchise/FireEmblem'':
** While some games partially avert this by making some legendary weapons available early on, they still qualify by not making TheHero's available until the final few chapters. In addition, most games in the series feature a [[GuestStarPartyMember super-powerful recruit]] who only joins for the final chapter. This character archetype is so common that it's got a nickname among the ''Franchise/FireEmblem'' community: the "Gotoh", after its first example. Others include Karel from ''VideoGame/FireEmblemTheBindingBlade'', Athos from ''VideoGame/FireEmblemTheBlazingBlade'', and two Laguz kings and a third's top General from ''VideoGame/FireEmblemPathOfRadiance''.
** Ragnell in ''Path of Radiance''. It's only usable for two-and-a-half chapters (out of more than thirty) in the entire game, but it's by far the best usable sword, being one of only two UnbreakableWeapons in the entire game, with good attack power and a ranged attack to boot. It allows the main character -- who's arguably the best playable character in the game even with normal weapons -- to rip through enemy hordes damn near single-handedly, and is the only equippable weapon that can damage the final boss. Ragnell goes to plot-defying lengths to conform to this trope. Ike presumably gets Ragnell much earlier in the storyline, but it doesn't appear in-game until the 3rd-to-last chapter. Even then, the sword waits until the end of that chapter to magically appear in Ike's inventory, at which point it becomes vital to use.
*** Ragnell [[AvertedTrope averts this trope]] in ''VideoGame/SuperSmashBros Brawl''. When Ike uses it there, it's no more or less powerful than any other sword.
** The sequel, ''VideoGame/FireEmblemRadiantDawn'', kicks this up another notch. In one of the last five chapters, you obtain [[spoiler:Alondite, Ragnell's counterpart, except that ''any sword user'' can equip it.]] You also get [[spoiler:every laguz king except Dheginsea]] before those final five chapters. Add to that that after 2 chapters you can make a weapon unbreakable for every character, you get a lot of these this game. On second playthrough, on you get [[spoiler:Lehran; look at his [[http://serenesforest.net/fe10/char_base.html stats]] -- the cap in general is 40 and he has that in FIVE STATS to start. Granted, Lehran takes more work than any character ever in any ''Fire Emblem'' game to unlock, but he will make the fight easier.]]
** Additionally, while it's only the Eleventh Hour Superpower of Part 1 (of four), you also get [[spoiler:the Black Knight, who literally cannot be killed by any enemy units]], but he still has a death speech.
** A notable example is the titular "Sword Of Seals" in ''Fire Emblem: The Binding Blade'', since it allowed you to dominate the remaining chapter (chapters if you had all of the other legendary weapons) with almost complete ease. The only real problem with it is that only the main character can use it. Which wouldn't be a problem normally (Roy's a pretty good character), but Roy doesn't class change until he gets the sword. What this means is that you're going up against basically level 36 enemies with someone at max level 21. Oh, that and the whole only 20 uses thing.
** The Naga tome from ''VideoGame/FireEmblemGenealogyOfTheHolyWar'' also counts, as you get it nearly right before fighting the final boss, and it has 30 Might (though all holy weapons are that powerful) and adds a grand total of '''''80''''' points in stat bonuses (Most legendary weapons in ''4'' provide a total of 30 bonus stat points... while in other entries in the series, legendaries rarely provide over ''5'' bonus stat points) and negates the final boss's ability to halve attack power. [[RuleOfCool It also summons a giant glowing dragon to attack.]]
** In ''VideoGame/FireEmblemAwakening'', two chapters away from the end, Chrom's Falchion is upgraded to the Exalted Falchion, which is the most effective weapon to use against [[spoiler: Grima]].
** ''VideoGame/FireEmblemFates'''s Avatar gets more powerful versions of his/her Yato as the game progresses, but the 'final' upgrade always comes at the penultimate chapter, after Yato's current form fails to leave a scratch on the penultimate boss. Which form it takes depends on the route the Avatar takes, (Shadow, Blazing, or Omega) but the form that truly embodies this trope is Omega Yato, only possible on the ''Revelations'' route after all five divine weapons are reunited, the most effective weapon against the final boss, and [[spoiler: this game's Fire Emblem]].
*** In the final chapter of the ''Heirs of Fate'' DLC [[spoiler: the two Kanas combine their Shadow and Blazing Yatos to turn them both into Omega Yatos to defeat Anankos.]]
* Frequently used in the ''Franchise/{{Metroid}}'' series.
** In ''VideoGame/SuperMetroid'', the all-powerful Hyper Beam is granted to Samus halfway through the final boss battle for use there and during the LoadBearingBoss escape sequence.
** ''VideoGame/MetroidFusion'' is unique in that the boss-killing superweapon is the Ice Beam, a series staple which is typically gained midway through the game.
** In ''VideoGame/MetroidPrime'', the Phazon Beam serves a similar purpose (your HUD even reads "Hyper Mode"). In fact, since ''Super Metroid'', every game in the series has had an anti-final-boss weapon of this sort.
** In ''VideoGame/MetroidZeroMission'', the Fully Powered Suit is rewarded for beating the penultimate boss. You also get the Power Bombs shortly after that, but by that point, very little game time is left unless you want to collect all expansions and this seems to be the only reason the Power Bombs are even in the game.
** In ''VideoGame/MetroidPrime2Echoes'', Samus gets the Light Suit, which allows her to navigate Dark Aether unharmed (previously, the poisonous atmosphere of Dark Aether would make Samus take constant damage)and to travel across Aether through beams of light; however, she only gets this shortly before going to the SupervillainLair.
** In ''VideoGame/MetroidPrimePinball'', the Force Ball is acquired at the start of the final boss fight.
** ''VideoGame/MetroidPrimeHunters'' features the Omega Cannon, which can later be unlocked for multiplayer (where it's an outright OneHitKill).
** ''VideoGame/MetroidPrime3Corruption'' also put a twist on it by [[SecondHourSuperpower giving you access to the uber-weapon only a few hours in]] [[DangerousForbiddenTechnique but limiting its usage]]; when the endgame hits, you lose access to all weapons ''but'' that one. Putting you in constant danger of death in the process.
** In ''VideoGame/MetroidOtherM'', the [[BigBulkyBomb Power Bombs]] function as the ultimate boss-killing weapon (in previous games their main use was making navigation/collecting easier). [[GuideDangIt Too bad the game doesn't tell you they have been enabled.]] You keep them in the PlayableEpilogue, which allows you to obtain all the items.
* Dart's Divine Dragoon transformation and Rose's Dragon Buster sword in ''VideoGame/TheLegendOfDragoon''. Although you can backtrack through the last dungeon (but [[PointOfNoReturn not out of it]]), you receive it literally just before the final boss.
* Pandora's Box in the first ''VideoGame/GodOfWar'', and the Blade of Olympus in the sequel (although you could also use the Blade [[ATasteOfPower for a little while in the beginning of the game]]). Pandora's Box is interesting in that it doesn't actually make Kratos more powerful game-wise, but story-wise, it's what grants him the power to defeat Ares.
* ''VideoGame/{{Kirby}}'' games love to give you a special power for the final boss. These include the Star Rod in ''VideoGame/KirbysAdventure'', the Rainbow Sword in ''Kirby's Dream Land 2'', the Love-Love Stick in ''Kirby's Dream Land 3'', the Crystal + Ribbon combo in ''VideoGame/Kirby64TheCrystalShards'', the Master sword in ''VideoGame/KirbyAndTheAmazingMirror'', and the Triple Star in ''VideoGame/KirbySqueakSquad''. The latter two can be used in regular levels after beating the game (and, in the case of Triple Star, unlocking the ability room), and can take care of ''all'' otherwise ability-specific obstacles.
** The Starship in ''VideoGame/KirbySuperStar'' and [[PowerUpMount Landia]] in ''VideoGame/KirbysReturnToDreamLand'' may count as well, except for the fact that they are used for {{Unexpected Shmup Level}}s found late in the game and not against the actual final bosses.
*** [[spoiler: Robobot Halberd Mode]] from ''VideoGame/KirbyPlanetRobobot'' is also [[spoiler:an UnexpectedShmupLevel, albeit a ''VideoGame/StarFox''-based one, but it actually is used against the final boss.]]
* ''VideoGame/SaGaFrontier'' does this no less than three times -- In Blue's game, after mastering magic after the battle with Rouge, finding T260's Omega Model body in the penultimate dungeon, and Red only gets learns Re-Al-Phoenix after he uses Al-Phoenix on [[spoiler:TheDragon [=MBlackIII=]]].
* At the end of ''VideoGame/StarTrekEliteForce'', you encounter a recharge station that increases both of your ammunition types (Federation energy and dilithium-based) to far beyond the previously imposed limits, just before the climactic battle.
* ''Videogame/DirgeOfCerberus'' has Vincent Valentine transform into Chaos and [[CrowningMomentOfAwesome pull his ultimate weapon, Death Penalty, out of thin air]] for the final level.
* ''VideoGame/LostPlanet: Extreme Condition'' gives you an incredibly agile, flight-capable Vital Suit very near the end of the game; prior only to a short corridor of enemies (to learn the controls) and the final boss. The suit controls so differently than any other that it might be considered an UnexpectedGameplayChange.
* ''VideoGame/ZoneOfTheEnders: the 2nd Runner'' has two of these. The first is Jehuty Version 2, gained just before the final dungeon, which is twice as strong as normal Jehuty. The second is Naked Jehuty, gained just before the final boss, which is ten times stronger than version 2 and can tear through [[DegradedBoss former bosses]] like wet tissue paper.
* In ''Franchise/ShinMegamiTensei: VideoGame/DigitalDevilSaga 2'', Serph [[spoiler:fuses with Sera into the superbeing Seraph, whose demon form has no weaknesses]] in TheVeryDefinitelyFinalDungeon (also a PointOfNoReturn).
* Done incredibly well in the game ''VideoGame/TheDarkness''. The final part of the game, an attack on the BigBad's mansion, takes place during a solar eclipse which massively augments your darkness-based powers. Might not sound all that impressive until you actually ''see'' what you're capable of (which is mostly made up of [[CutscenePowerToTheMax cutscenes that showcase your newfound power]]). Darklings, goblin-like minions spawned in small numbers to help you out, are spawning of their own accord by the dozen and swarm all over the place. The Black Hole ability, which...well...creates small black holes, is powerful enough to rip walls to pieces and pull in enemies from dozens of metres away. The Darkness Shield, which protects you from attacks, is strong enough to withstand a minigun barrage from a ''helicopter gunship''. The Demon Arm, a spiked tendril used to impale enemies and throw them about, is used by the protagonist to pluck said gunship out of the sky and smash it to pieces. The only ability that doesn't demonstrate any obvious increase in power is Creeping Dark, a wall-crawling demon head used to scout distant areas and attack from safety, but it still puts the fear of God into the mooks you're fighting to the point where one of them throws himself through an upper-story window to escape from it.
* Either Li, Yuan, or Sammo from the Inheritance chapter of ''VideoGame/LiveALive'', depending on who the Xin Shan Quan Master's Inheritor is, is granted one shot of their level 16 attack, Xuan Ya Lian Shan Quan, for the last boss battle of their chapter. This attack usually knocks off 1/3 to 1/2 of the boss' health. Since it's unlikely, verging on impossible for any of these characters to hit level 16 during their chapter, this counts as an Eleventh Hour Superpower. Of course, in the game's FINAL chapter, it's entirely possible, if not exceptionally easy, for these characters to hit level 16 and become gods of death, seeing as this is the only level 16 technique, save for Pogo's (which causes sizable stat debuffs on him after use), that fires off as soon as you select it.
* [[VisualNovel Not a traditional game per se]], but Avalon in ''VisualNovel/FateStayNight'''s "Fate" route works as such. Avalon is only returned to Saber before the final battle, who uses it when she was losing for a comeback victory (Shirou also Traces a copy, and does the same for ''his'' battle). Arguably, Unlimited Blade Works (in the route of the same name) and both the aptly-named Rule Breaker and Excalibur (in ''Heaven's Feel'') also perform the same function.
* In ''VideoGame/XMenLegends II: The Rise of Apocalypse,'' you get to try out the powers of the Four long enough to trash Apocalypse's powering-up device (it's the only way to do it, and if you don't, Apocalypse simply revives there the instant you defeat him).
* While this isn't really a solely end-game instance, it IS very late in the game and only available to one class. In ''VideoGame/QuestForGloryIV'', as a Wizard, you get Erana's Staff (Erana, for those unfamiliar, was an extremely, EXTREMELY powerful magic user who, with her magic, managed to enchant no fewer than six different places as "Peaceful" areas, where no violence of any form can work. In [[VideoGame/QuestForGloryIII QFG3]], you see a cheetah lounging near an antelope in one of these spots. Even after she died, her staff alone managed to generate spontaneous flora and the same peaceful-type area. Also, it was able to force lesser undead to stay away, and make greater undead REALLY uncomfortable near it.) After getting the staff, you can return to one of her enchanted places and face down the Faerie Queen. Doing this gives you access to the Resistance spell, which drastically reduces ALL magic damage done to you, and really costs nothing because of the staff itself being a veritable fountain of magic. So, this is actually TWO examples, the Staff and Resistance, which turns a Wizard into an engine of death (moreso than previously, at least.)
* ''VideoGame/{{Drakengard}}'' has a strange example of this for its FinalBoss fight. [[spoiler:[[UltimateEvil The Queen Mother of the Grotesqueries]] begins to sing once it arrives in Tokyo, of "light and dark, good and evil." The mission is to silence its song. To do this, you emit the song back at the monstrosity so that the two cancel each other out.]] While being deeply [[WhatDoYouMeanItsNotSymbolic symbolic]] of the protagonist's [[BalanceBetweenGoodAndEvil embodiment of humanity as a whole]], it is [[TrueArtIsIncomprehensible mind-bogglingly impossible]] to describe how this conflict would take place in any world other than that of [[ThePhilosopher Plato]]nic Forms or similar realms of [[AscendToAHigherPlaneOfExistence higher existence]]. The symbolism is the reality, which leaves one clawing out their own eyes wondering where the reality is.
* In ''VideoGame/AgeOfMythology'', the ever-withholding Zeus finally hands down a blessing to Arkantos that makes him a demigod in, yes, the FinalBoss scenario. Seems a lot more could have been accomplished by doing this earlier. Comes with free strange godly garb and [[PowerEchoes echoey voice]].
* In ''VideoGame/GodHand'', the player begins the game as Gene, having just had his dismembered arm replaced by the God Hand, an arm formerly belonging to a mythical fighter who originally defeated the Demon King Angra. [[spoiler:Just before the player throws down against Angra himself, Azel, his rival, who possesses the aforementioned mythical warrior's other arm, dismembers himself and gives the extra arm to Gene before being possessed by Angra, enabling Gene to fight Angra with both of the original God Hands. During the fight, Angra will occasionally summon the demonform enemies that used to be full fledged minibosses in their own rights -- you can now kill them with three moderately weak hits.]]) Finally, after that event, you learn (for the final fight only) the Double Shaolin technique. It's the most powerful attack in the ''entire game.''
* In ''VideoGame/LegacyOfKain: Soul Reaver 2'', you happen to be awarded the game world's ultimate weapon just before the final boss rush. This weapon isn't just extrememly powerful, but also makes you invincible, thereby turning what you'd think would be a tough climactic battle into [[CurbStompBattle a series of one-sided smackdowns]] that's actually possible to lose.
** The ''Legacy of Kain'' games seem fond of this. ''Blood Omen 2'' and ''Defiance'' both equipped you with the fully powered Soul Reaver for the final boss. Blood Omen 2 allows you to use the Soul Reaver in a New Game+, where its main advantage is that it's unbreakable.
*** ''Defiance'' actually does it twice. For the final mission as Raziel, you get the deadly Spirit Reaver upgrade, which rips through mooks in that level like wet tissue. It replaces the previous elemental Reaver upgrades you've obtained during the game, as the Spirit Reaver's power makes them obsolete (and you have no more elemental puzzles left to solve).
*** Kain, meanwhile, gets the restored Soul Reaver for use on the final boss. However, this is only for the story and not for the gameplay: using the developer's console to use the restored Soul Reaver outside of said boss reveal that it's only programmed for average strength.
* In ''VideoGame/PaperMario'', the Peach Beam, which you can't defeat Bowser without, is granted halfway through the final boss battle. What's more, the game doesn't allow you to keep playing after beating the boss, instead returning you to your last save point.
* Don't forget about ''VideoGame/PaperMarioTheThousandYearDoor''.
** Played straight with the Shadow Queen. Halfway through the battle, Mario's Crystal Stars go out to all over the world, and the various people they've met all give their support to him, causing the Shadow Queen to lose her invincibility.
* In ''VideoGame/EarthBoundBeginnings'' (predecessor to ''VideoGame/EarthBound''), the final boss is toppled by [[spoiler:singing a song comprised of the 8 melodies collected during the game. The player receives the actual song prior to entering the final boss battle.]]
** Earthbound's final boss was killed in a similar manner, where [[spoiler:a character prays several times, using an ability that up to that point was almost useless. The only thing that prevents this from being a complete GuideDangIt is that Porky hints that you should use the command. Well, kind of...]]
-->'''Porky''': I know you have telepathy, or something. So just try and call for help, you pathetic so called heroes of justice!
** The MASSIVE stat boost that Ness gets at the end of the Magicant level also counts as this, as does Poo automatically learning PK Starstorm Omega upon entering TheVeryDefinitelyFinalDungeon.
** ''VideoGame/MOTHER3'' has one too. You get [[spoiler: PK Love Ω]] for pulling the sixth needle. There are ''seven'' needles.
* In ''VideoGame/SecretOfMana'', you didn't get access to the true power of the sword until you fight the final boss. One thing that was interesting is that the game leaves a gap in the spell lists of the Girl and Sprite and also doesn't allow you to upgrade to tier nine sword with the orbs, meaning that one could figure out something was going to happen if they stopped and thought about it a little (Dryad explicitly says that [[BigBad Thanatos]] sealed her magic).
** Of course, using a glitch, the player is entirely able to get an extra orb for the sword and create the Mana Sword, which then becomes a GameBreaker in and of itself.
* In ''Franchise/TheChroniclesOfRiddick: VideoGame/EscapeFromButcherBay'', after spending the entire game using stealth and the occasional small-arms shootout to make your way through the prison, the final level grants you access to a [[HumongousMecha giant, heavily armored walking tank]].
* ''VideoGame/{{Halo 3}}'''s final confrontation gives you an infinite-ammo Spartan Laser for use on the final enemy. Its infinite ammo drastically sets it apart from the previous Spartan Laser you used in a previous mission, who's ammunition was so limited that it made the weapon AwesomeButImpractical.
* ''VideoGame/{{Psychonauts}}''' Eleventh Hour Superpower is a crackling field of psychic energy that allows you to grow to [[AttackOfThe50FootWhatever monstrous size]], given to you by [[spoiler:your father, who was secretly [[SecretLegacy a psychic all along]].]]
* ''VideoGame/Condemned2Bloodshot'' has [[spoiler:The Voice, which lets you explode the heads of your enemies along with disabling their brain-damage-causing emanations long enough for you to apply the beatdown.]]
* In ''VideoGame/{{Aquaria}}'', the Eleventh Hour Superpower was the character's final form, given just before the final boss: [[spoiler:although, just as you were finally getting used to having a power that could kill nearly anything on screen, it was taken away after the first form of the final boss, until the LAST form, leaving you to have to figure out other methods for those in between.]]
** Interesting in that you can stop the boss fight between the second and third forms and go off to do other stuff - but Celia apparently doesn't feel like stopping time anywhere else.
* In ''VideoGame/JakAndDaxterThePrecursorLegacy'', at the very tail end of the final battle with Gol and Maia's giant robot, all four benevolent forms of [[GreenRocks Eco]] combine to form ''Light'' Eco, the only substance that can completely negate the Dark Eco threatening to subsume the world. Once that happens, the entire remainder of the battle consists of simply ''getting to the stuff'' while the ground vanishes and the robot begins firing wildly at you and enemies attack from all directions. Since it seems to give you the abilities of all the other Eco combined and boosted, along with invincibility, the game just throws you into the end cutscene as the [[CurbStompBattle Curb Stomp]] [[OneHitKill Kill]] ensues. In short: once you grab it, you win.
* In ''VideoGame/MassEffect2'', [[DemonicSpiders Harbinger-possessed]] [[EliteMooks Collectors]] start dropping heavy weapon ammo in the final fight, which makes the whole thing massively easier.
* The "anti-god" enhancements to your weapons in ''VideoGame/PennyArcadeAdventures: On The Rain-Slick Precipice of Darkness: Episode 1''. More or less [[JustifiedTrope justified]] since the characters specifically sought out something which would allow them to defeat a god, but this doesn't explain why your weapons were also ten times as powerful against ordinary {{mooks}}...
** Would ''you'' want to be punched in the face with [[spoiler:''extremely concentrated urine''?]] Or make raked in the face with [[spoiler:''the soul of the evil leader of a mime-ish cult''?]] Rain-Slick Precipice takes plenty of RefugeInAudacity, but the second game runs things a little straighter, with a more gradual increase in weapon power. [[spoiler:And then a giant ''doll'' shows up to viciously rape the end boss.]] RefugeInAudacity, TurnedUpToEleven.
* The final boss of ''VideoGame/FreshlyPickedTinglesRosyRupeeland'' sees Tingle use all the rupees he has collected in the game to power himself up so he can fly and shoot rupees. If all the rupee goods have been collected in the game, another power up will also be activated, boosting Tingle's stats and turning his suit [[RealMenWearPink pink]].
* Appears during the final battle against Cynder in ''[[VideoGame/TheLegendOfSpyro The Legend of Spyro: A New Beginning]]''. You were given an immense purple fury which threw ''heads shaped like Spyro'' at your opponent until she fell down. Granted, it was pretty cool, and you weren't immortal while using it.
* At the end of ''VideoGame/EternalDarkness: Sanity's Requiem'', you have to defeat the main enemy, Pious the Lich, as well as the dark god that the player chose at the beginning of the game while playing as Pious. You, as Alex Roivas, defeat them by [[spoiler:summoning the dark god that directly opposes the one Pious summons. To summon it, you have to place the proper runes in a nine-rune "Circle of Power" which happens to be the largest circle in the game, in terms of having the most runes, in addition to spanning an ''entire city''.]]
** Another Eleventh Hour Superpower is essentially an InfinityPlusOneSword that can only be obtained by collecting and placing various figures at certain chapters throughout the game. Alex Roivas collects it at the beginning of the final chapter. It's permanently enchanted, plus it can be thrown at enemies (making it an infinite-ammo ranged weapon, since it reappears in her hands shortly after).
* In ''VideoGame/FinalFantasyVII'', if by the very last battle you don't have the LimitBreak Omnislash yet, [[spoiler:you automatically get it, and it's the only command available. Unless you select 'Defend' or just sit there not choosing anything - then Sephiroth hits Cloud once, and Cloud counterattacks once, and the final cut scene plays as normal.]]
** Perhaps the coolest part about that battle is that, using the in-game explanation of Limit Break being the result of increasing anger, [[spoiler:Cloud's limit break gauge slowly increases during the intro to the battle, showing him getting angrier and angrier until he devastates with Omni-Slash.]]
* ''VideoGame/MetalGearSolid2'' has the High-Frequency Blade, a katana-like blade that slices enemies up and can even block bullets. The catch? You don't get it until almost at the end of the game, when [[spoiler:Solid Snake gives Raiden his clothes back and also gives him the HF Blade, and it's only useful during the battle in the infamous FISSION MAILED chamber and in the very final battle with Solidus Snake]].
** ''VideoGame/MetalGearRisingRevengeance'' gives Raiden [[spoiler: Sam's HF Murasama]] for the final boss [[spoiler: which allows him to cut through his nanomachine-reinforced skin.]]
* ''VideoGame/TraumaCenter'' has a strange one. At the end of the final operation, your 'Healing Touch' (which seemingly slows down time) automatically activates, as it has in operations before. The twist? If you haven't used it yet, you can use your use-anytime HT as well ''on top of'' the scripted one, and stop time, which indicates that Derek is activating the healing touch with both hands. This is the only way to win.
** In the sequel, ''New Blood'', your time-slow Healing Touch gets upgraded to stop time in the last part of the final operation (where it is again needed to win). This is not explained. Or mentioned. Or even noticeable most of the time, since the final boss spends most of the window you have to activate it standing still. But it happens.
* In the final level of ''VideoGame/{{Crysis}}'', your suit gains the (plot-dependent) ability to short out the alien drones, and you get a nuclear grenade launcher, both expressly for the purpose of taking down the final boss. You're not even allowed to use the cannon on anything else. It is available in Multi-player as a Doomsday Weapon, though.
** The Expansion Pack ''Crysis Warhead'' lets you grab an absolutely overpowered plasma rifle that can one shot a heavy tank, something nothing else can do except the demo charges. However, it's not required to kill the final boss (since the thing is vulnerable to other weapons), but it makes killing it both easier (because of its ridiculously high firepower) and harder (very limited range, it's not a sniper rifle), as well as extremely [[RuleOfFun fun]].
*** It will also compel you to shout ''Get some!'' as you rip through the enemies you've been running from for hours. This will cause confusion for those in the adjacent room.
** In ''Crysis 2'', the last 3 levels have most of the MIKE maser guns found in the game, which is good news considering the fact that ''every alien in Manhattan is out to get you'' as you're [[spoiler:heading straight for their HQ]]. The suit also gains the ability to [[spoiler:re-purpose their supervirus into a weapon against them]], which is how you win.
* The ''VideoGame/SiN'' ExpansionPack ''Wages of Sin'' similarly gave you a nuclear rocket launcher at the end of the game, although you were free to use it on anything you wanted (but you were probably better off saving it for the final boss).
* The final level of ''VideoGame/UnrealIITheAwakening'' gave you a gun that shoots black holes, which pretty much suck up and kill any enemy they even come close to. This weapon is the only thing that can kill the game's final boss monsters (whom it dispatches in one shot), but they're also armed with one, and can do the same to you. This weapon is so overpowered that a hit from an enemy will kill you ''[[NoFairCheating even if you have god mode turned on]]''.
** The kicker is that you first have to kill one of those creatures with only your regular weapons, while IT is armed with THE black hole gun you're going to be using the rest of the level.
* ''[[Franchise/ShinMegamiTenseiPersona Persona]]'':
** In ''VideoGame/Persona3'', during the final confrontation, the Main Character draws power from all the [[ThePowerOfFriendship people he's helped throughout the game]], giving him the power of the Universe Arcana. Then the other team members give their encouragement, powering up a final attack that saves the day. [[spoiler:And [[HeroicSacrifice takes his life.]]]]
** The protagonist of ''VideoGame/Persona4'' does the same against the final boss of the True Ending. [[spoiler:He is granted Izanagi-no-Ookami, the ascended form of his default persona, which he then uses to pretty much [[DidYouJustPunchOutCthulhu punch the everliving hell out of Izanami]], who was [[TheManBehindTheMan behind everything about The Midnight Channel, Ameno-Sagiri, and the fog that tormented the residents of Inaba, as well as being the one who gave the protagonist, Adachi, and Namatame their powers in the first place]].]] In a NewGamePlus, you can actually fuse [[spoiler:Izanagi-no-Okami]] as a normal Persona. He's about as powerful as you'd expect.
** The protagonist of ''VideoGame/Persona5'' also pulls this in the very last boss battle. [[spoiler:He summons Satanael, his Ultimate Persona, who ''shoots the final boss in the head'' with a MASSIVE rifle]]. And like ''4'', you can summon [[spoiler:Satanael]] on a replay, though not until late in the game because it has a very high level. Unlike ''4'' however, it DOES get registered in the Persona compendium, meaning that on a 3rd playthrough, you can get it right off the bat, and pretty much effortlessly stomp your way through the game.
** Speaking of ''Persona 5'', Morgana unlocks his ultimate persona, [[spoiler:Mercurius]], as he and the protagonist fall asleep on the night before Christmas Eve, the day the Phantom Thieves descend into [[TheVeryDefinitelyFinalDungeon Depths of Mementos]] for the final portions of the game.
* ''VideoGame/FinalFantasyVIII'': You can draw a magic called Apocalypse from the final boss's final form. This magic isn't available anywhere else in the game (hence you can't Junction it; hacking it shows that it works better than practically anything) but can be used for some major damage, as it's one of the only abilities which goes above the normal damage limit of 9999.
* ''VideoGame/ChronoCross'': The eponymous "Chrono Cross" is actually an optional Element you can only get near the end of the game. Although it does refill your used Elements under certain circumstances, its main use is to get the good ending when used against the final boss, which also completely bypasses the final boss fight.
** It's also used in a special spot to combine party members from other saves.
* ''VideoGame/KingdomOfLoathing'': The final part of the final boss needs a special object in your inventory, the Wand of Nagamar. It takes the boss's powerful spells, and changes the way they work by turning them into anagrams. When you get this far, you can't lose.
** It should be noted that the Wand of Nagamar (Nagamar is an anagram of... well, Anagram, for those who hadn't figured it out yet) is practically useless outside of that particular fight due to its abysmal power; a mere 40 out of a possible 200. This can actually make it hard for non-combat classes such as the Sauceror and Pastamancer to progress in the initial two stages of the boss fight due to having to rely on their spells -- which may not always work -- and having no real melee power as backup with which to finish off the stages.
** This has been changed, though -- now you don't have to actually equip the wand, you just have to have it in your inventory.
** Facing your Nemesis' final form turns your Legendary Epic Weapon (which by this time is obsolete) into your Ultimate Legendary Epic Weapon, with its own Ultimate Special Attack. It's only 11th Hour in terms of that questline, though -- defeating the Nemesis leaves you with the weapon and special attack, both of which are [[GameBreaker gamebreakers]] for the remainder of the main questline.
* ''VideoGame/MegaManX5'' hides the [[spoiler:Ultimate Armor for X and Black Armor for Zero in a wide pit in the third fortress stage,]] although you can technically start with them by using built-in cheat codes at the character select.
** The first ''VideoGame/MegaManX'' has Zero give you his ArmCannon in the final stage, which upgrades your blaster significantly. Of course, experienced players will be well aware that you can find this upgrade (and several others) much earlier, but it's nice that the game gives you a freebie if you didn't find it before.
** In ''[[VideoGame/MegaManX3 X3]]'', you can get the golden armor (upgrading all your armor parts at once) and Zero's saber near the end of the game.
** In ''VideoGame/Rockman4MinusInfinity'', [[spoiler:if you find yourself losing the final battle against [[DualBoss the Petit Robot Masters]], Proto Man comes in to give you the Wily Buster and refill all your health. The Wily Buster shoots charged shots instantly and reduces all damage taken from the bosses.]]
* In ''VideoGame/MegaManBattleNetwork'', Mega Man.EXE gets a special update just after losing to TheDragon in the end, making it possible to win. Technically, you probably could win without it, though.
* In ''VideoGame/TombRaiderLegend'', you [[spoiler:get Excalibur in Nepal.]] It's used only to [[spoiler:break open a door to leave and to fight Amanda and the unknown creature]].
** In ''Underworld'', you acquire [[spoiler:Thor's hammer, Mjolnir,]] several levels before the end, and [[{{Gamebreaker}} get to use it to wreak godlike havoc on enemies]], be they simple gun-toting humans, sharks in water(!), or the various thralls [[spoiler:emerging from the depths of Nifleheim, before ultimately planting it into the ''Big Bad'''s backside.]]
* In ''VideoGame/HomeworldCataclysm'', the manual says something easily forgettable about your fighter designs (which were traded to you) having their original weaponry replaced by standard guns, as the designs didn't work. In the last mission, you get the corrected plans -- and find out that your standard fighters now use [[WaveMotionGun ion cannons]], which are usually mounted on capital ships.
** In ''VideoGame/{{Homeworld 2}}'', the penultimate mission has you trade in your iconic mothership for Saijuuk, a {{Precursors}} ship that lacks the mothership's build capabilities (hopefully you still have a carrier and shipyard), but packs an epic WaveMotionGun. Said WaveMotionGun is the only thing that can harm the bombardment platforms the BigBad sics on your home planet. Had the BigBad not gone after Saijuuk, thereby giving you the opportunity to steal his hyperspace core, [[NiceJobFixingItVillain you would have been helpless against these platforms]].
* In ''VideoGame/SaGa3'', the only way to actually damage Xagor is to have the 4 Mystic Swords; magic helps, but the swords are the only weapons that will actually deal physical damage to him.
* ''VideoGame/TheWorldEndsWithYou'' has a strange example of this occurring mid-game. Joshua gains a powered-up attack at the very end of the fifth day of his week. You get two days with his powered up form. This sounds longer than it is - a "day" is essentially a "chapter" in the game, and the final two days are relatively short and constrained to a relatively small area. After they're up, Joshua and his superpowered form leave until [[NewGamePlus after you complete the game]].
** There is another, straight version of this trope applied during the final boss battle. During this battle, you're forced to fight alone. However, at regular intervals throughout the fight, an ActionCommand will appear on the top of the screen, healing you and boosting your attack power. Once you get the boss's health low enough, a gigantic Fusion Pin appears on the screen, allowing you to use your [[LimitBreak Fusion Attack]] with ''all three partners at once''. While this "Quad Fusion Attack" merely serves as a flashy ending, it does reinforce the whole PowerOfFriendship theme.
* The final level of ''VideoGame/GearsOfWar2'' puts you in the pilot seat of a [[spoiler:40-foot tall Brumak, bustling with machine guns and rocket launchers]]. Suffice it to say, from that point on everything that gets in your way dies really quickly.
* Both ''VideoGame/SoulBlazer'' and ''VideoGame/IllusionOfGaia'' have a Phoenix-based projectile, only unlocked in the last area, and the only way to damage the final boss. However, ''[=SoulBlazer=]'' does unlock it in the middle of the last zone, and you can leave and use it in previous areas.
* The last mission of ''VideoGame/HostileWaters'' gives you the Vulture, a quick, cheap, heavily armed air unit. Unfortunately, it is utterly useless in that particular mission.
* At the end of Chelsea's part in ''VideoGame/BunnyMustDie'', Chelsea fights [[HopelessBossFight Dechronos's second form]]. The player then starts playing as Bunny wearing a new gold bunny suit, which makes her automatically parry any attack and gives an ability to [[ThrowingYourSwordAlwaysWorks throw]] [[{{BFS}} big fragging swords]].
** {{Justified|Trope}} in that Bunny was [[DemonicPossession body-jacked]] by Dechronos just moments before said HopelessBossFight, as Bunny only has the gold suit in the battle against her and this final battle - and nowhere else in the game. Dechronos really should have known better than to use for his mortal vessel (however temporary) a character who is aware of him and had every intent to shut him down.
* In the strategy game ''TabletopGame/{{Warhammer}}: Mark of Chaos'' and its novelization, both playable sides get this: The chaos champion transforms into a Daemon Prince after obtaining the MacGuffin while the Empire protagonist is given back his family's title of Elector Count, which carries with it access to a cool rune sword and the imperial menagerie containing a rideable griffon. In the game, the placement of both are more SwordOfPlotAdvancement with a full chapter remaining, while the novel had them used only for the last battle (especially the griffon).
* Before the final mission of ''Superhero League of Hoboken'', Toastbuster and Zaniac join the party. Toastbuster has the highest Brawn in the game, and Zaniac comes with the insanely powerful Power of Confusion.
* In ''VideoGame/PokemonBlackAndWhite'', your legendary dragon is this in the main storyline, as it can only be caught right before fighting [[spoiler:N and Ghetsis]]. Given the high evolution levels of many Unova Pokémon, it may well be the strongest Pokémon you have encountered up to this point. Of course, you can choose to [[DefiedTrope defy]] this by ''not'' putting the dragon in your party (though you still have to catch it to proceed).
** In the final mission of ''VideoGame/PokemonRanger: Shadows of Almia'', you are given the Vatonage Styler, which allows you to befriend any Pokémon, even if it has been hypnotized by Gigaremo Units. This is an Eleventh Hour Superpower because there are no Gigaremo Units in the game after this mission is completed. Also, you cannot even damage the final boss [[spoiler:([[OlympusMons Darkrai]], implied to be the King of Almia reincarnated)]] until said Vatonage Styler is further upgraded by fusing with the Tears of the Princes. There is no use for this gem power outside of the final boss fight, so enjoy the pretty animation while you can.
* There are many boss fights and quest-related events in ''VideoGame/WorldOfWarcraft'' that give your character a temporary (and occasionally massive) increase in power, which is generally required to overcome the challenge in question. Specific examples:
** One of the earliest examples occurs in Blackwing Lair with Vaelastrasz, a corrupted, fully-grown red dragon capable of [[CurbStompBattle wiping the floor]] with you and your friends. Fortunately, he [[DeathSeeker wants to be killed]] and so gives the raid a buff that enables everyone to go crazy with maximum damage output for three minutes.
** Kael'thas in Tempest keep (not to be confused with his weakened Magister's Terrace version) also does this -- the fight begins with him sending his four advisers at you one at a time. After killing them, their weapons spring to life, and killing them allows the entire raid to loot them to temporarily use as [[InfinityPlusOneSword Infinity Plus One Swords]], which are necessary in order to handle fighting all four of the aforementioned advisers at once and kill them before Kael'thas himself finally decides to start attacking you. The weapons in question fade after 15 minutes or when you leave the zone, but after the dungeon was changed to not require killing the first three bosses in order to fight Kael, a bored guild took these weapons to one of the earlier bosses and beat her down in record time.
** Kil'jaeden in Sunwell Plateau is another example -- at certain points in the fight, some of your characters can turn into dragons which can shield your group from his ultimate attack and breathe on them to drastically increase their attack and casting speed or regenerate large amounts of their health and mana.
** Towards the end of the Death Knight starting quest chain, when you are taking part in the assault on Light's Hope Chapel, your character is given higher health and damage output (among other things) in order to compete with the Elite mob enemies at the Chapel.
*** Likewise when you have to defeat Patchwerk back in Acherus almost immediately afterwards.
** Much the same thing occurred during the now unavailable Battle for the Undercity quest -- if you were an Alliance player, you got to be escorted by Varian Wrynn, while if you were with the Horde, you got to run with Thrall -- in either case, you got a HUGE buff to your health, damage, and healing that turned you into an unstoppable one man army.
** The Ulduar raid dungeon features some bosses whose mechanics involve powering up the raid. The first is Hodir, a frost giant whose [[BossArenaIdiocy room comes prestocked]] with frozen allies that you can thaw out to get some nice buffs, which are necessary for most groups to kill him within the time limit. It's taken to the ultimate conclusion in the FinalBoss fight with Yogg-Saron, in which you can choose to be assisted by any or all of the four bosses you freed from its MindControl earlier. They buff the raid's health, damage, healing, and damage resistance; however, you will gain more loot and bragging rights for killing him with the help of fewer Keepers. "One light in the darkness" indeed.
** At the end of the final boss encounter in Throne of the Tides, Neptulon buffs the party with PURE WATER, giving ridiculously high health and power to everyone, which you need in order to defeat the kraken Ozumat.
** Other times, you are simply given control of a powerful vehicle, drake or other things that are much more powerful than your character would usually be at that level. Though in those cases, if you were to go back for a daily quest or something one expansion later, you'd most likely be more powerful on your own than these, if there is a choice.
* Each class has a special skill available for the fight against [[BigBad Shiro Tagachi]], final boss of ''VideoGame/GuildWars: Factions.'' The skill temporarily replaces one of your other 8 skills, is lost when you enter a town or outpost, and is ''very'' good. Also, you're gonna need it.
* At the start of the final mission of 'Path of Fire' the second expansion for ''VideoGame/GuildWars2,'' [[spoiler:your ally Rytlock Brimstone gives you his FlamingSword Sohothin, to wield against the forces of the rogue war god Balthazar. It's absurdly powerful, doing outrageous DPS to any enemy within your reach and possessing a pair of devastating super moves that take ages to cool down but will basically wipe out anything around you short of the mission bosses themselves.]] You have to give it back once you're done, of course.
* In ''VideoGame/{{Crystalis}}'', only seconds before the final boss do you merge your [[ElementalRockPaperScissors elemental swords]] together into the eponymous blade, which, amongst having the attack power needed to defeat the final boss, also allows you to shoot out giant orbs of power at any time, essentially turning the final boss [[UnexpectedGameplayChange into a shoot-em-up game]].
* The first two ''VideoGame/ValkyrieProfile'' games do this. In the first's [[MultipleEndings best ending]], Lenneth is the only one who can do any significant damage to the FinalBoss because she creates the sword Glance Reviver before the fight. This also gives her access to the full version of her LimitBreak. In ''[[VideoGame/ValkyrieProfile2Silmeria Silmeria]]'', this happens when [[spoiler:all three Valkyries and Alicia merge into one being, The Valkyrie, essentially a full-blown goddess]], and again, only she can do any significant damage to the final boss, though there is apparently a hidden scene only shown if you slog through the battle without her.
** ''[[VideoGame/ValkyrieProfileCovenantOfThePlume Covenant of the Plume]]'', however, only gives it to you for the [[ShootTheShaggyDog worst]] of the three normal endings. In the best ending, you don't get a special sword, but you do get a GuestStarPartyMember.
* ''VideoGame/FinalFantasyCrystalChronicles'' does this with Ultracite. Only available during the very final boss, automatically casts Firaga, Blizzaga, Thundaga, Curaga, or a brief period of Invincibility.
** ''[[VideoGame/FinalFantasyCrystalChroniclesTheCrystalBearers Crystal Bearers]]'' does it too. When BigBad [[spoiler:Jegran]] goes OneWingedAngel, it inadvertently activates a SuperMode for Layle, which lets him [[SkySurfing sky surf]] as well as greatly increases [[GravityMaster his powers]].
* In ''VideoGame/{{Vay}}'', right before you head to TheVeryDefinitelyFinalDungeon, all of the elemental orbs combine with the pieces of Vay Armor you've found to allow it to be used to its full potential. It's the only weapon capable of dealing significant damage to the FinalBoss (as even PJ's Megablast and Inferno spells will barely scratch him), and reduces all magical damage against the hero to 25%. Simply put, if he gets killed at any point during the battle and you don't have a Phoenix Heart or Lifestone handy, consider yourself boned.
* Unusually for the genre, the [[ShootEmUp shmup]] ''VideoGame/RefleX'' has one in the final two stages: when fighting the ZODIAC Virgo, a HumongousMecha that has been totally owning everything else in the game up to this point, your ship is destroyed when hit with MoreDakka than its shields and armor can handle. Then it is revealed that your ship is in fact powered by a ZODIAC core itself (ZODIAC Ophiuchus, to be precise), and it suddenly gains glowing wing things and a reflection shield with infinite power. The rest of the fight is you owning the Virgo, as only one of its super-powered attacks can even harm you now (so long as you keep the shield up). You keep this upgrade when fighting [[FinalBoss ZODIAC Libra]] and [[MeleeATrois two Kamui fighters]] in the [[VeryDefinitelyFinalDungeon Very Definitely Final Stage]]. \\
Sadly, it does have a vicious twist. The NoHoldsBarredBeatdown delivered by the boss kills the [[TheHeroDies pilot]], and when she is dead the ship's AI (aka ZODIAC Ophiuchus) kicks in and activates the ship's full power. Also, the ship's armor is gone, meaning that one bullet that slips past your shields or one missile -- missiles [[ArmorPiercingAttack ignore shields]] -- [[OneHitPointWonder is all it takes to get a]] GameOver.
* ''VideoGame/BillyHatcherAndTheGiantEgg'' gives you the ''[[ExactlyWhatItSaysOnTheTin Light Ball]]' (which apprently stems from the [[PlotCoupon Courage Emblems]] you've been collecting), and allows Billy to turn the Shadow Balls that [[BigBad Dark Raven]] shoots at him into 'Light Balls', which can be used like regular eggs, and is the only thing that can make Dark Raven vulnerable to damage.
* ''VideoGame/CityOfVillains'' has one for each character class in the Barracuda Strike Force. [[ThoseWackyNazis The 5th Column's leader, Reichsman]], is completely and utterly invincible thanks to the effects of a machine that takes energy from others and siphons it into him. The heroes defeat him in the Dr. Kahn Task Force by making a gun to nullify the effects of the machine. The villains instead round up the four [[TheDragon Arachnos Patrons]] by lying to Lord Recluse, throw them in there, and siphon the power of the Patrons themselves into the team so they can stand against and strike down Reichsman. In addition to defense and damage buffs, [[TheBrute Brutes]] gain an immunity to the effect that causes Reichsman to be near lethal in close-quarters combat, [[GlassCannon Corruptors]] get the ability to summon devils, [[MindControl Dominators]] get the ability to keep the entire room bar the team and Reichsman still, [[{{Ninja}} Stalkers]] get access to the swith that [[KillEmAll kills all of Reichsman's minions]], and [[TheMinionMaster Masterminds]] can switch off Reichsman's invincibility. If you lack any of them, you're in for a tough fight.
* In ''VideoGame/KingdomHeartsBirthBySleep'', Aqua gets the game's best Keyblade in [[spoiler:the Final Episode, the semi-hidden true conclusion to the game's storyline.]] It also forces you to use it in the secret episode added in the final mix version.
** Plus, for the final battle of the prologue section of Kingdom Hearts II, Roxas gets to dual wield keyblades for the final showdown with Axel. It plays like Sora's drive version, except there isn't a gauge, so it's basically unlimited.
** Upon entering the final world in ''VideoGame/KingdomHeartsChainOfMemories'', Sora is given an ability called "Trinity Limit" which gives you the ability to decimate any enemies on the screen provided you obtain one Goofy and Donald card during the battle.
* ''VideoGame/KingdomHearts358DaysOver2'': Roxas gains the ability to [[DualWielding dual wield the Oathkeeper and Oblivion Keyblades]] during the first part of Day 358 (the last mission). His attacking speed and power increase dramatically, letting him quickly kill the Neoshadows that spawn with only one or two hits.
* The second half of ''VideoGame/{{Nox}}'' is completely dedicated to assembling the ultra-powerful Staff of Oblivion, and yet you only get to use it against Hecubah and a few ''Mooks''.
** Ironically, although the Staff does effortlessly vacuum up Hecubah's mooks, it's actually only modestly effective against her (despite the whole point of assembling it being to have a weapon capable of defeating her). Instead, its best use seems to be stunning her for a second so you can hit her with a heavy spell like Fireball or Fist of Vengeance.
* Late in the penultimate level of ''VideoGame/BioShock2'', you get the final plasmid, which is rightfully described as ''"It's Bring Your Daughter to Work Day"''. You're the strongest and most powerful thing in all of Rapture, and Eleanor is [[DaddysGirl just like Daddy]]. [[BadassFamily Together, you can just plow through about everything the city has to throw at you.]]
** The Gatherer's Garden in the final level has the Telekinesis 3 plasmid upgrade, which allows Delta to pick up and throw live splicers at each other.
* In ''VideoGame/BioShockInfinite'', your Eleventh Hour Superpower comes in the form of [[spoiler:being able to control Songbird]], just in time for the final battle. It proves to be extremely effective, being able to down gunships and large areas of enemies with ease.
* In ''VideoGame/StarControlII'', you receive a fleet of ridiculously powerful battleships free of charge just before you venture into the final battle.
** On the flip side, your main ship -- which you can build into an even more ridiculously powerful badass of a ship before that point -- gets neutered into near uselessness at the same time. Considering that the main ship, when fully specialized for combat, is more powerful than all twelve of your other ships put together, this is actually a downgrade if you ignore the one-shot plot weapon added to the main ship.
*** Contrary to general opinion, it is possible to unlock Chmmr Avatar ships before the final ship refit. And they will be sold for money, and not for free. On the other hand, the last leg of the plot consists of a grand total of a single run through hostile territory (where it's entirely possible to avoid anyone and everyone - as your movement isn't impaired), and a grand total of two battles (one of which is basically autocombat with 6 Chmmr Avatars, and the second one is a cakewalk by Pkunk Fury).
* In ''VideoGame/MagicalGirlLyricalNanohaAsPortable: The Battle of Aces'', Reinforce's FinalBoss fight against Material-D is greatly simplified by [[spoiler:Hayate acting as a [[FusionDance unison device]] for her (!), giving her all 18 {{Power Up}}s in the game.]]
* In ''VideoGame/BlazBlueContinuumShift'', the Arcade Mode's final battle is against Hazama/Terumi. As Ragna, you get [[SuperMode Blood Kain]] always-on without [[DeadlyUpgrade its life-loss]] effects.
** Ragna's Azure Grimoire (the source of said powerup) in general. It's permanently grafted into his arm, but he seldom uses it. It's seen in action only in the aforementioned Terumi battle, his final battle with Unlimited Hakumen and Nu in Calamity Trigger's true ending, and as a probably non-canon BonusBoss in Calamity Trigger arcade mode. Why he dislikes using it is yet to be revealed.
*** ''Continuum Shift's'' story mode reveals why: [[spoiler:Ragna's Grimoire is actually what's left of the Black Beast. In his Bad Ending, its power consumes Ragna and turns him into another Black Beast that has to be put down by Jubei and Rachel.]]
** A villainous example occurs at the finale of ''Central Fiction'' [[spoiler:with [[BigBad Yuuki Terumi]] [[HeroKiller killing Hakumen]] and [[GrandTheftMe taking over the Susano'o Unit that his soul occupied]]. The twist is that said Unit is the body of the Japanese God of Storms Susanoo...[[GodOfEvil and it originally belonged to Terumi]]. He then proceeds to use the Unit's full power (Hakumen at his best only used up to 40% during the events of the series) and]] [[CurbStompBattle demolishes five of the strongest characters in the franchise without breaking a metaphorical sweat]]. It's pretty clear that he was only allowed to do this then [[TheBadGuyWins because the plot would have been over in minutes any time earlier]].
* In ''VideoGame/SaGa2'', aka ''Final Fantasy Legend 2'', your world's CrystalDragonJesus joins your party for the final dungeon. Her stats are completely maxed out and she's got the best attacks in the game. However, she leaves just before you fight the (very tough) final boss.
** [[spoiler:To be fair, she leaves you to go fight an exact clone of the final boss all by herself.]]
* If you get a new mecha in the last few stages of a ''VideoGame/SuperRobotWars'' game, expect it to be a total gamebreaker. Here are a few: the [[spoiler:[[Anime/EurekaSevem Nirvash Spec 3]]]] from the last stage of SRW Z, [[spoiler:Alfimi]] in Impact and in OG 2, and in the good ending of Alpha 3, [[spoiler:you get reinforcements on the last stage in the form of the Nashim Gun Eden, the final boss of Alpha 2, WITH HER FINAL BOSS STATS INTACT. It's pretty much impossible for her to be killed because of that massive HP bar, but you only get her after the final boss is around half dead.]]
** At the second-to-last stage of OG Gaiden, Raul rescues his companions, who board the Excellence Lightning. ''And start acting as '''subpilots''' for the Lightning.'' It carries over into the final stage as well. Well-upgraded, Raul can practically solo the last two stages after this event.
** Alpha Gaiden offers [[spoiler:Sanger Zonvolt in his Thrudgelmir]]; although it is downgraded from [[spoiler:his]] self, it's pretty much the best unit in the game. It has high HP and Armor, not so bad mobility (which isn't really needed), a nice set of weapons, and EN and HP regeneration L, making it pretty much unkillable. Considering the game is pretty NintendoHard, it isn't enough to solo the remaining stages alone, but getting [[spoiler:him]] makes the TrueFinalBoss fight against [[spoiler:Shu Shirakawa]] MUCH more easier.
** In ''[[VideoGame/GaidenGame Dark Prison]]'' where Shu Shirakawa is the headlining protagonist, him acquiring [[spoiler: the Neo Granzon]] is treated as an EleventhHourSuperpower as he first has access to it [[spoiler: after conning Shiva Volkruss, who surprisingly is just a DiscOneFinalBoss as you still have 7 more stages to go]] and at the final stage of the game. He doesn't use it during the other stages because he treats it as his trump card.
** Thanks to a mandatory event in scenario 56 of ''VideoGame/SuperRobotWarsZ: Tengoku-hen'', the entire cast attains the permanent status buff called "[[spoiler:Shinka]]"[[note]]Maximum Will +50, maximum Spirit Points +50, increase base damage to all unit weaponry by 2000.[[/note]]
** Several units in ''VideoGame/SuperRobotWarsV'' have final attacks or upgrades that are only unlocked in the last five stages of the game, such as the [[OriginalGeneration VangNex/GranVang's final attack]], [[Anime/CrossAnge Vilkiss's True Ability Unlock]], [[Manga/GetterRobo the Shin Getter's/Shin Dragon's Shin Shine Spark]], [[Literature/MobileSuitGundamHathawaysFlash the Xi Gundam's Missile Pod]], [[Anime/MobileSuitGundamZZ the Double Zeta's Full Armor Parts]] (though those can be obtained earlier through as a secret), [[Anime/MartianSuccessorNadesico the Nadesico C's Phase Transition Cannon]] and [[Anime/SpaceBattleshipYamato2199 the Yamato's Wave Motion Gun.]]
* In ''VideoGame/{{Fahrenheit}}'', Lucas Kane gains implausible martial arts skills just as he's being held up by several police officers. Granted, this happens at a point that's equivalent to the DiscOneFinalDungeon.
* ''VideoGame/{{Sudeki}}'' does this too. After collecting the people of your own realm and their darkness counterparts, you set our for the final boss battle. Before engaging him, each of the characters fuse with their darkness counterparts to become complete and overly powerful, but you only get to play one full character out of the remaining four. The others are parted by a barrier.
* In ''VideoGame/FinalFantasyX'', after beating the final forms of [[spoiler:Braska's Final Aeon (Jecht)]], another series of battles starts up to eventually show the TrueFinalBoss. Because the Fayth as a whole want this to happen, they aid you by giving your characters a permanent Auto-Life - the only way to die is to suicide by stoning.
* In ''VideoGame/WildArms2'', the protagonist's SuperMode is powered by a demon sealed away hundreds of years ago combined with the holy sword used to seal it away. The final battle occurs after the demon breaks free, leaving only the sword that the protagonist was unable to draw at the beginning of the game. One WorldOfCardboardSpeech later, he's blasting the demon with [[CombinedEnergyAttack Combined Energy Attacks]] in his new "Hero of the Sword" form while the rest of humanity makes speeches about not leaving him to fight alone.
* In ''ComicBook/ScottPilgrim's [[GrandFinale Finest Hour]]'', the title character gets one in the form of a sword called "the Power of Understanding", after realising that he and the BigBad Gideon are NotSoDifferent. Natural, due to the heavy video game influences.
** Not just that, but in the video game adaptation, you get the obscenely-powerful Power of Love Sword in the final stage of the game, and you only have it for fighting the penultimate boss. Luckilly, there's a cheat code that allows you to use it throughout the entire game.
* In ''VideoGame/WingCommander: Privateer'', as you're headed towards an ambush planned by the navy for the [[NeglectfulPrecursors Steltek]] drone that was following you the whole game, a Steltek ship appears and offers to upgrade the (already super-powerful) Steltek gun you've found earlier. You can decline, but it's unwise, since the upgrade is the only thing capable of even making a dent in the drone's shields.
* In the Wii version of ''VideoGame/ABoyAndHisBlob'', you get the InstantAwesomeJustAddMecha jellybean right after [[spoiler:Blob is brought back to life via the boy's SwissArmyTears]]. Because you can easily trample over all enemies with it, you only use it in the last two levels.
* In ''Literature/FineStructure'', Ching absorbs the power of the BigGood just in time for the FinalBattle with the BigBad.
* In ''VideoGame/DragonAgeOrigins'', you gain the ability to call upon reinforcements during the [[spoiler:siege of Denerim.]] It helps even the odds in the FinalBattle, since the FinalBoss is summoning its ''own'' reinforcements too. In ''Awakening'', you can activate Tevinter Towers in the final dungeon that will grant you several one shot combat abilities such as mass healing, mass stun, and a damaging fire blast that are only available during the FinalBattle. [[spoiler:Siding with the Architect]] will also grant you an even more powerful fire attack aptly named "Cataclysm".
* In the sixth scenario of ''VisualNovel/RadicalDreamers'', a previously found jewel enables Serge to summon a giant to fight against Lynx's [[spoiler:giant mecha.]]
* Just before the FinalBoss of ''VideoGame/BionicCommando: Rearmed'', you get the Bazooka upgrade, which allows you to freely control its shots. However, you can keep playing after beating the game and use this weapon everywhere else.
* In ''VideoGame/{{Purple}}'', you get Final Frisbee right before you fight the final boss's [[MakeMyMonsterGrow enlargened form]].
* In ''VideoGame/FableI'', you get an InfinityPlusOneSword - two variations with the different flavor but same function depending on alignment - at the end of the core story. It is pretty much guaranteed to be your main weapon throughout the short and brutal Lost Chapters.
* In ''VideoGame/RogueGalaxy'', the main character Jaster gets a glowy power aura of strength and a {{BFS}} with infinite reach to defeat the [[SequentialBoss final form]] of the TrueFinalBoss.
** He also gets this with his fight with Seed and another person in the desert town, only minus the BFS.
* In ''VideoGame/EverquestII'', this trope is in full force in the Vasty Deep: The Vestigal Cella zone. The boss of the zone can summon her elite guard, who can one-shot most people. If you burn her slowly, though, a dragon who you fought before will fly in and imbue you with the power of the seas, massively increasing your health and your damage to fight off the elite guard.
* ''VideoGame/MightAndMagic VII'' gives you blaster guns for your final two missions, the latter of which will upgrade you to {{BFG}}s. It's a considerable upgrade from the swords, daggers, and staves you'd been using up to that point.
** VI does something similar (the third mission from the end is all about ''getting'' blasters, but the second-to-last mission is non-combat and rather short), with the addition that blasters are actually ''necessary'' to win the game, rather than just very, very useful. Of course, in both games, you might want to go off and get a few more levels (for the skill points necessary to get better at hitting with your new 'superpower') before continuing with the main story, and it is entirely possible to have much of the game left after getting the blasters (the games do not end after the main quest does, and there are plenty of side-quests).
* ''VideoGame/{{Fallout 3}}'' has the Tesla Cannon from the Broken Steel DLC, an incredibly powerful shoulder-fired electric cannon that uses only one Electron Charge Pack, one of the most common ammo types, per shot. The earliest you can obtain it is at the final battle against the Enclave at Adams Air Force Base. Where it will be incredibly useful, given the insane number of Power Armor-wearing Enclave personnel there. And unlike "Take It Back!" from the core game, you have to fight them by yourself, with no Liberty Prime or Lyons' Pride backing you up.
** Likewise on of the more powerful armors in the game, the Tesla armor is only found after you are kidnapped by the Enclave, who also tend to carry high end and hard to find guns.
* ''Franchise/TheElderScrolls''
** During the course of the ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]'' main quest, an event occurs which grants you IdealIllnessImmunity. Given that the setting is positively ''rife'' with Common and Blight diseases which lower your attributes and hinder progress, this is an extremely helpful power to gain.
** ''[[VideoGame/TheElderScrollsIVOblivion Oblivion]]'' inverts this: Martin who [[BarrierMaiden is the only one who can fix the Oblivion Crisis]] has spent the whole game tagged as Quest-Essential, meaning he can't be killed. In the last two missions of the main quest (the Great Gate and the Seige on the Imperial City), he looses that tag meaning he can be killed, which gives you a game over. And seeing as friendly NPC's tend to have [[LeeroyJenkins suicidal]] [[ArtificialStupidity tactics]]...
** ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'' gives you the "[[BrownNote Dragon Rend]]" shout, which makes dragon killing a LOT easier and is received towards the end of the main quest line. Bonus points as you often find or are taught shouts throughout the main quest line and receive Dragon Rend because you are actively ''trying'' to find out how [[BigBad Alduin]] was beaten [[SealedEvilInACan last time]].
* ''VideoGame/SecretOfEvermore'' has the Energize power, granted via Call Bead near the end of the game: It allows the use of {{Charged Attack}}s instantly, meaning your robot dog can rather effortlessly BeamSpam the final bosses to death. It's not very beneficial to the player character, due to his ultimate weapon of a bazooka lacking a charged attack (though it doesn't need it).
* In VideoGame/{{Iji}}, the Massacre, which is obtained after completing a successful pacifist run.
* ''VideoGame/InFamous'': the final karmic choice, just before the final boss has you decide to activate or destroy the Raysphere. Destroying it sets your karma to maximum whereas activating it sets your karma so low it will never rise, gives you an extra 6 health slots and gives you a damage boost and cool colour change.
** ''VideoGame/InFAMOUS2'' has this in the second-to-last story mission. A thunderstorm moves in when the mission begins, allowing Cole to draw power ''from the storm itself'', [[BottomlessMagazines allowing the player to recharge anywhere]].
** ''VideoGame/InfamousSecondSon'' plays with the trope: Delsin finally gets the Concrete power... [[spoiler:at its ''lowest'' strength, and can't change it to one of his better powersets. Luckily, Eugene brings in Core Relays to power it up]].
* Played straight and averted in the ''VideoGame/DeusEx'' series:
** Highly averted in the original game, as most of the high-damage weapons can be obtained early on. The reloadable rocket launcher (GEP Gun) can be received in the ''first level''. The plasma gun is obtained roughly a third of the way through the game (in a military base). The best melee weapon is found roughly halfway through the game. The only problem is finding the space to store all of them.
** In ''VideoGame/DeusExHumanRevolution'', the Plasma Rifle is only received after fighting the second-to-last boss.
*** At which point there's an UnexpectedGameplayChange, and the weapon becomes almost useless, since you don't really have any heavy enemies to fight (just a bunch of freaked out civvies who rush you). It may become useful again when facing the FinalBoss, though.
* In ''VideoGame/SiN'', the experimental fusion pulse rifle can only be obtained three levels from the endgame, and requires the assembly of several different pieces (the first of which is obtained very early in the game). Somewhat toyed with; while it is a deadly weapon in its own right, and is capable of killing most enemies from that point on with a couple shots, it won't do much good against the final boss.
* The battering ram from ''VideoGame/{{Bastion}}'', although due to its limited range and slow attack speed, [[AwesomeButImpractical you might wish you could just use your normal weapons instead]].
* ''VideoGame/DemonsSouls'', of [[NintendoHard all]] [[TrialAndErrorGameplay possible]] [[DifficultButAwesome games]], gives you this in the Shrine of Storms, to avoid forcing an effective game restart for any melee-focused character. Against the [[GiantFlyer Storm King]], the final boss of this world, make a dash for the abandoned [[SuspiciousVideogameGenerosity Stormruler]] sword, and you'll be throwing RazorWind around like so much candy. It's strong enough to be superior to the innate damage potential of most ranged or magical characters, making it a weapon of choice for them as well, and to avoid balance issues, it loses most of its power outside of the Storm King's domain. Not, of course, that an InfinityPlusOneSword will make this boss ''easy''... it's still not that kind of game.
** No, what makes this boss a joke is the safe spot behind the ruined house which protects you from his one, telegraphed attack.
* ''VideoGame/CastlevaniaOrderOfEcclesia'' gives you a glyph that allows ''unlimited flight''... halfway through the final area. To be fair, you ''can'' use it in one of the {{bonus dungeon}}s. The one that's entirely focused on combat, but it's far from useless there. You also get three Dominus glyphs throughout the first half of the game, but using them together automatically kills you until the very end of the game where the combination is required to defeat the final boss.
* ''VideoGame/WarhammerOnline'' has the Lost Vale, one of the hardest PVE raid areas in the game. The final boss, N'Kari, is a terror - but this is offset by colored orbs floating in the arena that increase your DPS, healing, or hitpoints to crazy levels for a short time. Just make sure they pick up the right ones - having your ranged attackers gain a truckload of hitpoints, your healers get a buff to damage dealing, and your tanks become very good at healing is not good.
* ''VideoGame/AsurasWrath'' [[spoiler:has two. The first one is at the end of Act 2 Episode 12, where Asura turns into Berserker Asura, where he gains massive Glowing arms and can shoot down an entire space fleet with no effort, and it's never used again afterwards. The second time happens in act 3, Episode 18, and it is a really extreme example of this trope, Asura gets powered up by Mithra's prayer combined with her mother's guidance. He gains not 4, not 6, but [[SerialEscalation OVER]] [[ThereIsNoKillLikeOverKill 10]][[InfinityPlusOneSword 0]][[ReadingsAreOffTheScale 0]] pairs of arms that fuse into humongous gauntlets for the final battle.]]
** [[spoiler:Humongous gauntlets with rocket-boosters in the elbows (or at least that's what the effects look like).]]
** [[spoiler:What makes this even more ridiculous is that it's hinted that his six-armed form was originally this at the beginning of the game, as Asura never was able to use this form in any of the flashback episodes that had him fighting. This makes all the examples really extreme, because it implies he'll eventually regain the ability to use all of the power-ups by sheer ANGER alone!]]
** [[spoiler:An even better example of this is [[AttackOfTheFiftyFootWhatever Destructor Asura.]]]]
* ''VideoGame/PerfectDark'': It's not in the last level, but the [=RCP-120=] comes at just the right moment in [[ThatOneLevel the hardest level in the game]] for Joanna Dark to grab it, activate the InvisibilityCloak, and sneak past a dozen guards to defuse a bomb before it destroys the Institute.
* In ''VideoGame/MSSagaANewDawn'', it's both [[Anime/MobileSuitGundamCharsCounterattack the Nu Gundam and the Sazabi]].
* ''VideoGame/AssassinsCreedBrotherhood'' plays with this trope. [[spoiler:You get the Apple of Eden, basically the tool of God, late in the game. Besides counterkilling, which only kills one person at a time, it also has a special attack in the form of an InstantDeathRadius and a wider, second radius that makes those within kill each other or kneel before you. With the Apple, you destroy the armies of main villain Cesare Borgia and get him arrested for his crimes. It is subverted, however, when you have to fight and kill him in a classic swordfight in the very last level.]]
** In ''VideoGame/AssassinsCreedRevelations'', [[spoiler:the final Altair level has a 93-year old Altair use the Apple of Eden to fight the Mongol Horde sacking Masyaf. Unlike Ezio, the Apple is not CastFromHitPoints.]] Also, near the end of the game, Ezio leads the Assassins on an all-out assault upon the Arsenal. During the assault, he has infinite Assassin Signals, meaning that he can call upon assassins to rain down arrows as many times as he wants.
* In ''VideoGame/KidIcarusUprising'', you are given the Three Sacred Treasures to use in Chapter 9 and the ensuing fight against Medusa. [[spoiler:Subverted, however, since Medusa is far from the final boss, and Hades, the real villain, outright destroys the Three Sacred Treasures when Pit tries to use them against him. This is followed by Pit obtaining the Great Sacred Treasure, a giant, all-powerful mech suit. However, Hades inflicts more and more damage to it throughout the battle, causing it to change into smaller and smaller forms; he outright destroys the Great Sacred Treasure near the battle's end, and (after some timely and completely unexpected [[MegatonPunch assistance]] from Medusa) you are forced to use the G.S.T's cannon to charge up the final strike that decimates Hades' body, defeating him.]]
* In ''VideoGame/DuelSaviorDestiny'', this happens multiple times by use of differing forms of various characters, but the most obvious of these is the one that takes place right before the final boss, where Taiga transforms into Super Taiga, which in terms of gameplay is Taiga with far better range, slightly better speed and damage, and the ability to autoblock like bosses do. In terms of story, [[spoiler:he's actually more powerful than God.]]
* The ''VideoGame/XCOMEnemyUnknown'' remake has your squad StormingTheCastle in the form of a giant [[TheMothership Temple Ship]]. One member of the squad, the Volunteer, has reached a point in his or her psychic training that a new [[PsychicPowers psi-ability]] is unlocked -- the Rift, which creates a SwirlyEnergyThingy that persists for a few turns, dealing damage to anyone in its radius. Since you're constantly getting stormed by the aliens, the ability is useful, although not really a GameBreaker. In fact, the first time you use it, the BigBad will compliment the Volunteer on his or her achievement ([[spoiler:it turns out that the whole AlienInvasion was a SecretTest to turn humans into powerful warriors, combining strength, endurance, intelligence, and [[PsychicPowers the Gift]] for... [[BiggerBad something]]. Given that you destroy the aliens at the end of the game, the plan has GoneHorriblyRight. Also, the BigBad pretty much states that all the aliens you have been fighting were earlier failures to create the perfect soldiers]]).
** The sequel ''VideoGame/XCOM2'' also features this. The last mission gives you a very powerful psy-soldier with a unique gun to boot and very useful psy abilities. The extra soldier also breaks the 6 team member limitation as the 7. soldier, which is a very helpful boost. [[NintendoHard And you will need it.]]
* ''VideoGame/{{Bioforge}}'': Near the end of the game, your character acquires the ability to fire a destructive beam out of his wrist.
* ''VideoGame/ShadowWarrior'': Upon re-forging the Nobitsura-Kage shortly before the final level, you are now able to perform your greatest crowd control technique WITH EVERY NORMAL SLICE (comparable to throwing chainsaws with the speed and skill of throwing shurikens). It is as awesome as it sounds.
* ''Videogame/DarkMessiah'':
** While not introduced in the finale, but certainly in the protagonist's darkest hour, Sareth learns he is [[spoiler:the titular Dark Messiah, and the son of what is essentially the deity of evil]]. His darkest hour? [[spoiler:He was impaled on a spike by Arantir. His son-of-a-god revelation brings him back from the dead]].
** Also at this point, Xana, the [[spoiler:succubus]] living in his head for most of the game, grants him a temporary [[spoiler:demon form which deals mass amounts of damage and moves extremely fast]]. Very useful considering you have to get back all of your equipment.
* ''Videogame/DawnOfWar'':
** ''Dawn Of War II'' has the final mission against the Tyranids. You start with your four squads as usual while your strike cruiser is attacking the hive fleet in orbit. When the Armageddon is too heavily damaged, your other two squads come in via emergency drop-pod. Then [[spoiler:Gabriel Angelos shows up, and helps you fight the final boss.]] Who has a damage shield. Good thing [[strike:Gabriel]] comes with an ability that destroys shields and one that makes all squads invulnerable.
** In Retribution, the final battle against [[spoiler:Azariah Kyras]] gives you a free orbital bombardment to take him out.
* ''VideoGame/TheBindingOfIsaac'''s VeryDefinitelyFinalDungeon starts you off with a room containing four locked chests. Better have four keys ready, because these chests are programmed to give you items normally found in the Treasure Room. And there's a pretty decent chance that one of these items will guarantee your survival.
* In ''VideoGame/{{Vanquish}}'', after destroying one of [[BigBad Zaitsev's]] suits, the other one starts moving much more quickly, so Sam has Elena [[DangerousForbiddenTechnique disable the limiters]] on the [[PoweredArmor ARS]] to even the odds. Gameplay-wise, this doubles the amount of time you can spend in [[BulletTime Augmented Reality.]]
* In ''Videogame/FarCry3BloodDragon'', Rex gains the Killstar in the penultimate mission of the game. It's essentially the glaive from Film/{{Krull}} if it fired a laser that insta-gibbed enemies. While it is CastFromHitpoints, the drain is slow enough to be largely inconsequential. However, doing the mission that nets you it automatically puts you in the endgame, forcing you into the final mission.
* In ''VideoGame/TalesOfXillia2'', Ludger [[spoiler:unlocks the full power of his Chromatus]] during the final boss fight, which gives you a fancy new Mystic Arte to finish him off with. You can carry it over into a NewGamePlus, too.
* In ''VideoGame/SaintSeiyaOugonDensetsu Kanketsu Hen'', Seiya gets an inmense boost in "Sevensenses", a new really strong attack and the ability to refill his life and [[LifeEnergy Cosmo]] bar every turn after doing [[PuzzleBoss the right moves]] against the FinalBoss. This makes the player virtually invincible.
** The other three Saints (Shiryu, Hyoga and Shun) gain a new ultra-powerful attack (or two) during their respective boss battles in the previous three Temples. What makes them fit here is that these boss battles are their last, since (in concordance with the [[Manga/SaintSeiya manga/anime]] the game is based off) they each "die" (are removed from play, here) fighting their bosses.
* In ''VideoGame/LufiaCurseOfTheSinistrals'', Maxim gains the Dual Blade right before the FinalBoss battle, along with its ability to freeze time. [[spoiler:The TrueFinalBoss in NewGamePlus gives another Eleventh Hour Superpower in the form of {{Sword Beam}}s.]]
* In ''VideoGame/{{Hacknet}}'', [[spoiler: [=TraceKill.exe=]]] is this. As its name implies, [[spoiler:it completely suppresses any active trace while running.]]
* ''VideoGame/WithinADeepForest'' has the final ball form that allows you to fly. Speed runs tend to sequence break to get this power much sooner than intended in order to blitz through earlier sections of the game.
* At the end of ''Videogame/{{Lisa}}: The Painful RPG'', just before the final battle Brad not only gives in to complete and total despair but also [[spoiler:begins to succumb to [[PsychoSerum Joy]] Mutation]], which causes his in-game class to change from "Nobody" to "Failure". This replaces any abilities he had with superpowered versions and he gains the ability to either [[ScreamingWarrior cry out in pain]] (which induces fear in enemies) or [[BerserkerTears shed tears for his sister]] (which restores his PP).
* Played with in ''VideoGame/DriverSanFrancisco''. Most of the game takes place in Tanner's coma dream, which allows him to [[BodySurf shift]] into any car on the road. In the penultimate chase, shifting is replaced with the ability to throw cars at Jericho. However, the ''final'' chase takes place in reality, after Tanner wakes up; all of his abilities like shifting and boosting are taken away, making you rely on pure driving skills.
* In ''Franchise/ChaosRings'' ''III'', the True Incarnatus -- a glowing giant with extremely high stats that acts as a replacement for the entire party and can use all of the active members' abilities -- can only be used against the final bosses. While the final ''final'' boss is more or less a CutsceneBoss, the one preceding it is tough enough that it's still a struggle to beat it even as the True Incarnatus.
** ''[[VideoGame/ChaosRings Chaos Rings II]]'' gives the main character his level 3 Awakening, Godslayer, in the middle of the TrueFinalBoss. You get to keep it for the PlayableEpilogue and BonusBoss fights.
* During the TrueFinalBoss of ''VideoGame/{{Shantae}} and the Pirate's Curse'', Shantae manages to reclaim her genie magic [[spoiler:thanks to Risky's BatmanGambit with the Dark Magic]], allowing her to whip the Pirate Master for maximum damage. [[spoiler:Risky then provides a second dose of this trope by hijacking the Ammo Baron's Palace Disruptor Cannon, providing additional firepower to finish the Pirate Master off]].
* ''VideoGame/MinecraftStoryMode'': [[spoiler:Jesse gets an enchanted Diamond Weapon and a stronger suit of armor for the FinalBattle with the Wither Storm.]]
* ''VideoGame/ModernWarfare 3'' has a particularly weird example. The heroes have just waged and stopped World War 3, successfully prevented the conflict from going nuclear, and allowed a peace summit to take place. But just when the viewer is led to believe [[spoiler:Makarov is going to get away with starting the whole shebang, all of a sudden here come Price and Yuri with [[ImplacableMan Juggernaut Armor]], striding invincibly into every single wall of gunfire Makarov could possibly throw at them. For added weirdness, the "superpower" in question doesn't make it to the twelfth hour: the armor catches on fire from a crashing helicopter, forcing them to remove it and proceed normally for the rest of the level.]]
* In ''{{VideoGames/Fairune}}'', [[spoiler:the Mamono/Monster Slayer sword is used to give Hope Girl wings, a tail and a Sword Beam to fight the boss with. Taken UpToEleven in 2, with the new Fairune Sword and Photon Blade giving more elaborate forms, until the combined power of all three swords gives her something like an open top fighter jet.]]
* Depending on your definition, there is one or two in the final level of ''VideoGame/TitanFall2''. For the on-foot section, you get the [=SMART=] Auto-Aim Pistol, allowing you to easily carve a path through the enemy troops. In your Titan, you get access to the Legion loadout, that gives your Titan a [[GatlingGood Predator Chaingun]], and allows it to temporarily activate its' own auto-aim abilities with its' core ability.
* [[Videogame/ArmyMen Army Men II]] has a special infinite ammo bazooka that can be found on the last level.
* The final battle of ''VideoGame/{{Splatoon 2}}'' has [[spoiler: the player face off against Callie and DJ Octavio with assistance from Marie and Sheldon. Once Callie's shaken off the hypnoshades' lingering effects after Marie shoots them off, she jumps off of the Octobot King II, and]] Sheldon issues a non-exploding Rainmaker [[spoiler:with which to finish Octavio off]].
* In ''VideoGame/BlasterMaster Zero'', if you've fulfilled the conditions to enter TheVeryDefinitelyFinalDungeon, your SOPHIA III will be replaced with the SOPHIA [[TitleDrop ZERO]]. All of the ZERO's weapons and sub-weapons have improved attack power, and their {{charged attack}}s can be fired instantly, as long as it has enough energy to do so (except for the [[WaveMotionGun Acceleration Cannon]], which instead has its charge time cut in half), and it is immune to the blasting damage from the Cannon Shot's explosions.
* Inverted in ''{{VideoGame/Undertale}}''. At the end of the [[spoiler: Genocide route]] the player finds the [[spoiler: Real Knife and The Locket, a weapon with 99 ATK and an armour piece with 99 DEF respectively.]] However, there's only one enemy left in the game at this point, and [[spoiler: the items are completely useless as he dies in one hit anyway and all his attacks can only do one damage per hit. However, he repeatedly dodges your attacks without fail (up to a point) and his attacks are incredibly rapid, hitting up to 30 times a second, which no amount of defense will reduce.]]
* In ''VideoGame/XenobladeChronicles'', Shulk receives his InfinityPlusOneSword, [[spoiler:the Monado III]], right before the final phase of the FinalBoss. NewGamePlus allows the player to bring it over into the rest of the game.
** Shulk and the seventh party member both receive their ultimate arts, Monado Cyclone and Final Cross, towards the end of the game.
* In ''VideoGame/PlanetAlcatraz'', when the final objective becomes clear, the orbital station will drop your squad state-of-the-art Imperial weaponry and armor.

* In ''Webcomic/ElGoonishShive'', this happens ''three'' times. One had to be [[JustifiedTrope justified]] [[CerebusRetcon later]], another is justified in previous development, and the last one was built up in more than two years so that it was bound to appear and ''[[PersonalityPowers could not]]'' be anything less than Summon "OhCrap".
* In ''Webcomic/MSPaintAdventures'', pretty much everything that the titular ''Webcomic/ProblemSleuth'' does after [[spoiler:using Sepulchritude]] counts here, ending with him [[spoiler:using a burst of righteous charisma to destroy all of DMK's health bars]].
* In ''WebComic/SailorMoonCosmosArc'', after [[spoiler: Usagi's ascension into godhood/Sailor Cosmos]] the other Senshi power up into their Cosmic Sailor Senshi forms. This also had the effect of breaking Servant Chaos's possession of Hotaru, [[spoiler: reviving the Asteroid Senshi, and allowing this timeline's Chibiusa to ''finally'' transform.]]

[[folder:{{Web Original}}]]
* Invoked in ''Literature/{{Worm}}'', when [[spoiler:the imminent demise of humanity prompts Taylor to have Panacea tamper with her brain to try to remove the limits on her power. [[GoneHorriblyWrong It doesn't quite pan out how she'd hoped]]]].
** She had attempted this earlier by going to [[spoiler:Cauldron]] in search of a [[NextTierPowerUp second trigger]] or [[spoiler:a formula capable of creating a powerful cape]]. Neither panned out.

* In the middle of the third season of ''WesternAnimation/TransformersAnimated'', Prowl picks up the ability to use "processor over matter", which is basically telekinesis. [[spoiler:In the finale, Prowl and Jazz use this to pull together scattered pieces of the Allspark and convert them to use against the Lugnut Supremes -- and when that's not powerful enough, Prowl uses it to pull out his own spark.]]
* In the second seaon finale of ''WesternAnimation/Ben10AlienForce'', Azmith grants Ben the ability to control and transform into ALL the aliens in known existence in the Omnitrix (And there are a LOT more than just 10,000, actually more than a million). He was able to transform without having to manually slap the switch down, [[spoiler: which helps them get out of a prison situation]]. [[StatusQuoIsGod The Omnitrix resets back to its original settings]] [[spoiler:after Ben uses it to save the dying Highbreeds by splicing their DNA with other aliens.]] [[WhatAnIdiot It later comes to bite Ben in the ass]] [[NiceJobBreakingItHero when he and Kevin decide to hack it and get the same power]] in the upcoming fight with Vilgax in the new season... [[spoiler:only to not only get the aliens rampant and rogue, but mutated Kevin with an array of metals and substances making up his body]].
* The series finale of ''WesternAnimation/AvatarTheLastAirbender'' gives us [[spoiler:energybending, which acts as a PowerNullifier]].
** It came even earlier than that with the finale of Book One. After the moon is destroyed, Aang fuses with the ocean spirit, turning into an insanely powerful, kaiju-like being that annihilates the Fire Navy Armada.
** The first season finale of ''WesternAnimation/TheLegendOfKorra'' plays with this trope. [[spoiler:In the last episode of the first season, Korra gains airbending, [[DiscardAndDraw but only after she loses the ability to bend the other three elements]]. Later, she regains those bending abilities and gets access to the [[SuperMode Avatar State]]... but this is ''after'' the BigBad has been defeated. However, she also gains the ability to restore bending to anyone who lost it, which lets her help the BigBad's victims.]]
* ''WesternAnimation/KimPossible'''s battlesuit in ''[[WesternAnimation/KimPossibleMovieSoTheDrama So The Drama]]'' was originally supposed to be used only in one final showdown with Drakken and Shego. Then the series was UnCancelled and the writers had to [[StoryBreakerPower find ways to keep things challenging]]. In the first PostScriptSeason episode, Professor Dementor hacks into the suit to remote-control it, providing a rationale for Kim to be cautious about using it.
** In the [[Recap/KimPossibleS4E22Graduation final episode]], Ron manages to fully tap into his Mystical Monkey Power and curb-stomp a pair of villains, one of whom had defeated both Kim (wearing the battlesuit) and Shego in [[Recap/KimPossibleS4E6MadDogsAndAliens a previous episode]].
* In that Christmas perennial ''WesternAnimation/HowTheGrinchStoleChristmas'', the Grinch gets super-strength from his doubly-undersized heart "Growing three sizes that day".
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** In the episode "[[ChristmasEpisode Hearth's Warming Eve]]", when Windigos are attracted by the hatred between the three pony tribe leaders and begin freezing everything, the new friendship between the tribe leaders' assistants manifests as a magical flame that shoots from Clover the Clever's horn, vanquishes the Windigos, and melts the ice along with the leaders' hearts.
** Towards the end of the two-part season finale "A Canterlot Wedding", when Queen Chrysalis and her Changeling army have taken over Canterlot and left Shining Armor too weak to recast his defensive shield, Princess Cadance casts her [[ThePowerOfLove love spell]] on his horn, creating a barrier of love that expels the Changelings.
** In "[[Recap/MyLittlePonyFriendshipIsMagicS4E26TwilightsKingdomPart2 Twilight’s Kingdom - Part 2]]", "Rainbow Power", the force that was locked inside the box, is unlocked after Twilight turns over all the alicorn magic she had been storing and proves to be the key to defeating Tirek. However the key to unlock the box is generated from Discord's artifact he received from Tirek and he's only released after the exchange to turn over the magic to Tirek occurs, meaning Tirek had literally ''won'' by the time the Rainbow Power box is unlocked (so it's really more of a "Twelfth Hour Superpower").
* In the ''WesternAnimation/AdventureTime'' Season 6 finale, "The Comet", the thorn Finn got in his hand early in the season transforms his arm into an [[AbsurdlySharpBlade absurdly sharp]] thorny grass whip, which he uses to slice and dice [[DidYouJustPunchOutCthulhu Orgalorg]] and free the titular comet.
* In ''WesterAnimation/StevenUniverse'', the FinalBattle with Season 3 ArcVillain [[UltimateLifeform Jasper]] ends with Steven telling Amethyst (who'd become obsessed with [[TheOnlyOneAllowedToDefeatYou being the one to beat Jasper]] but was failing to do so despite her best efforts) YouAreNotAlone and she's got him. This understanding on both their parts results in Steven's finally successfully [[FusionDance fusing with a Gem]] when he and Amethyst fuse into Smoky Quartz.

* The creation of the atomic bomb during the final days of UsefulNotes/WorldWarII. The project to develop an atomic bomb ''did'' start in 1939, and the war ''might'' have ended much later than Summer 1945 if they hadn't been used, but to the general public[[note]]not the governments, though: Germany, Japan, Britain, and the Soviet Union all had their own atomic weapons research projects going, and the Soviets had a lot of informers inside the Manhattan Project[[/note]] the bombs seemed to come out of nowhere and then suddenly, peace.[[note]] While there is some debate among historians as to whether or not the atomic bomb was really the key factor, as some cite the Soviet invasion and the cessation of diplomatic relations as being more important, this is referring to the popular opinion especially in the US.

* A close villainous example with UsefulNotes/AdolfHitler. Soon after the landings in Normandy, he began to boast that Germany would soon possess incredible new "wonder weapons" which would completely destroy all the Allies. These included the Me 262 (the first operational jet fighter), the Type XXI submarine (the first ''true'' submarine, as it was built only for underwater use), and, most iconically, the V1 cruise and V2 ballistic missiles. Up to the last days of the war, these were reported by Goebbels' propaganda ministry to be capable of turning the increasingly desperate tide. However, all were a case of AwesomeButImpractical, consuming vast amounts of Germany's rapidly dwindling resources while having almost no tactical or strategic impact. The V2 rockets, in particular, killed more people building them (through slave labor) than their actual use on London.
* The [[RedsWithRockets Soviet]] concept of High Command Reserves. Untouchable by anyone without explicit authorization of [[UsefulNotes/JosephStalin Iosif Stalin]]. Included such goodies as High-Powered Artillery units, i.e. [[{{BFG}} 204 mm howitzers and 320 mm mortars]].
