->'''Inigo:''' I admit it: you are better than I am!\\
'''Man in Black:''' Then why are you smiling?\\
'''Inigo:''' Because I know something you don't know.\\
'''Man in Black:''' And what is that?\\
'''Inigo:''' I am not left handed! ''[switches the sword to his right hand and starts driving him back]''
-->-- ''Literature/ThePrincessBride''

A {{Combat Trope|s}} in which one of the combatants reveals that he's been holding back, but now decides it's time to take it up a notch.

The situation varies from example to example. A common example is for a character to fight with their non-dominant hand, as in the [[Film/ThePrincessBride trope-naming example]], only to switch back to their dominant hand to gain an edge. Similar to this is pretending that they have a serious handicap, then deciding to stop the charade. It can also go so far as a character revealing that they have always had a superpower [[EleventhHourSuperpower which they now decide to exploit]], or a DangerousForbiddenTechnique which they now [[GodzillaThreshold have no option but to utilize]]. The most common subversions are for the other character to also be not left-handed, or for the character to remark, "Yes I am," after he switches hands. (Or if the writer is [[NoManOfWomanBorn being subtle]] about [[DoubleSubversion doubling up]] on this trope, that the character is later revealed as [[SesquipedalianLoquaciousness ambidextrous]] a.k.a '''[[OhCrap "both-handed"]]'''.)

Villains can invoke this trope, as well. For more information on that, see our [[Analysis/IAmNotLeftHanded Analysis page]].

Has a couple of sub-tropes:

Heroic Examples:
* EleventhHourSuperpower
* CriticalStatusBuff
* DeadlyUpgrade
* MyKungFuIsStrongerThanYours

Neutral Examples:
* HustlingTheMark
* SuperweaponSurprise

Villainous Examples:
* OneWingedAngel
* TurnsRed

May be preceded by a WorldOfCardboardSpeech. Use of this trope, especially in sequence, can result in transfer of the AdvantageBall. See also: TheGlovesComeOff, RestrainingBolt, PowerLimiter, WillfullyWeak, JustToyingWithThem, CherryTapping, and FakeWeakness. Note that ForgotAboutHisPowers is not this trope, as it has nothing to do with deliberately holding back for calculated reasons.

'''May contain unmarked spoilers.'''


[[folder:Anime & Manga]]
* Fai/Fay in ''Manga/TsubasaReservoirChronicle'' begins the series with an elaborate phoenix tattoo which Yuuko demands as his payment for the fulfillment of his wish. Much later, it's revealed that [[spoiler: the tattoo was designed to prevent his magic from growing in power each and every time he uses it, as it would otherwise naturally do]]. The reason is [[spoiler:he's cursed to kill the first person he meets whose magic exceeds his own. Suppressing his magic only makes it more likely he'll run across someone stronger]].
** Just as a reminder, [[spoiler:without that limiter, Fay's magic can destroy an entire world/dimension/at least country when he has a SuperPowerMeltdown]].
* Used in ''Manga/{{Naruto}}'', when Jiraiya fights Pain: Jiraiya think he's won by [[spoiler:defeating Pain's three bodies]] then it turns out [[spoiler:Pain has ''three more'', and one of them can repair the others.]] Fittingly, he reveals this by [[spoiler:ripping off Jiraiya's ''left'' arm.]]
** When Pain fights Naruto, he believes that Naruto has used sage mode long enough, and it will expire shortly. It does, but Naruto has got a couple more sage modes stocked up elsewhere. He also generates more sage mode ''during'' the battle, while Pain is busy lecturing him.
** [[spoiler: A, the Raikage, thinks he is still stronger than Bee when the latter challenges him to a Lariat strike. However, Bee reveals he has surpassed him, and completely overpowers him ''without'' his Hachibi Cloak]].
** Early in the series, most of the time Kakashi raises his [[PowerLimiter headband]] to reveal his Sharingan, he's saying LetsGetDangerous.
** Also Rock Lee's fight with Gaara. At first, even with his speed, Lee can't get past Gaara's sand defenses. Guy tells Lee that it's time to pull out all the stops, and Lee starts taking off the weights on his legs. No one else thinks this would make much difference, and Gaara's siblings find it outright laughable... and then the weights shake the whole arena and form significant craters when they hit the floor. It turns out they were ''very'' heavy. Lee then resumes his attack, even faster than before and able to hit Gaara so fast his sand shield can't move fast enough to block him. Is then revealed that Gaara has a sand armor beside his sand shield and Lee attacks have not done any significant damage. Lee proceeds to introduce him to his Eight Gates Technique.
* In ''[[Anime/MagicalGirlLyricalNanohaStrikerS Magical Girl Lyrical Nanoha StrikerS]]'', the third season of the series, it's revealed that Nanoha, Fate and Hayate voluntarily put limiters on their powers in order to continue working together, officially because of the office politics of having too high a concentration of power in one unit, but actually to disguise the true power available to Section Six, [[OhCrap the reactions when the villains found out]] just how well this worked were priceless. On an entirely unrelated note, Nanoha herself ''is'' [[TheSouthpaw left-handed]].
* [[http://www.tsunamichannel.com/index.php?date=2003-09-19&comic=ExCoKo As does]] ''Webcomic/ExperimentalComicKotone'', but {{inverted|Trope}} in that Konstantin ''is'' left-handed. This is actually a better ruse because 90% of the population is right-handed, no one would notice anything strange if a person was using their right hand.
* Karasu in ''Manga/YuYuHakusho'' pretends that his power is to make anything he touches explode. Kurama tries to counter by fighting at a distance. But Karasu reveals that his real power is to make invisible bombs that he can move with his mind. '''BOOM'''.
** Younger Toguro gives us this gem after he's already powered up and begun dominating the fight with Yusuke.
--> '''Toguro''': What I've been telling you is a hundred percent is really more like eighty-five. (powers up [[UpToEleven even more]])
* In ''Manga/BlackCat'' Volume 2, Train Heartnet reveals that he is not '''''right''''' handed. As a matter of fact, he was originally left handed, learned to wield his pistol ambidextrously, and switches to his dominant hand to increase his fighting potential (i.e., speed and accuracy).
** A similar example is Maki in ''Manga/HayateCrossBlade'', who had always held her sword in her right hand until it was severely injured by her opponent. Another character explains that she had not been fighting with her full power previously, because the manner in which she was gripping the sword was completely different.
* Similarly, in ''Manga/ThePrinceOfTennis'', Ryoma plays his first match in canon with his right hand. He manages to upstage his opponent in this state, but eventually decides to reveal that he is not '''right''' handed, and completely crushes the terrified opponent. Ryoma is fond of confusing his opponents this way throughout the series.
** This is probably the most prevalent in Ryoma's showdown against Yukimura in the finale of the OVA, where Ryoma almost gets out-dueled by the much feared Yukimura, and falls to the ground exhausted, but suddenly wakes up in a DeusExMachina and out-duels Yukimura in reverse.
** Also, Inui purposely handicaps himself with heavy weights on his ankles, which he later removes to the shock of his opponent. He's not the only one who does so, either; the non-regular Arai also uses weights. As does every other character in the series in at least one match.
*** Tezuka, [[spoiler: as a first year, was already better than his sempais, so [[ValuesDissonance he hid the fact that he was better, to not insult them]]. When Tezuka's cover was blown, one of the sempais lost it and ''hit him in the arm with his racket'', this being the source of his infamous injury.]]
** This also happens in the second movie, Battle of the British City, where after Ryoma's reveal of being left-handed, [[spoiler: Keith]] also switches to his dominant left hand having been using his right hand for most of the match.
** Actually, this happens quite often, notable examples being in the manga.
*** During Kikumaru and Oishi's match against Rikkai's Niou and Yagyuu, it's revealed halfway through the match that Niou and Yagyuu have been imitating each other, and when they finally switched back to being themselves, their moves' power increase (helped by the fact that since Niou's dominant hand is his left, they've both been using their weaker hand up until the reveal).
*** Also with Shiraishi in the New Prince of Tennis, where it's revealed during a match that the reason his left hand was wrapped in bandages was because [[spoiler: underneath he was wearing a golden gauntlet.]] With that taken off, the power and speed of his shots become impossibly high.
* In chapter six of ''Manga/ZombiePowder'', It is revealed that Gamma purposely handicaps himself when he fights against women and children. At the time, Gamma was fighting an old man with the appearance of a child, and when he realized this, he began to fight seriously. And beat the mickey out of his opponent.
* Myojin pulls this in ''Manga/TheLawOfUeki''. Ueki thinks he's figured out how to beat him, then he reveals that unlike every other power user, he was given two special powers instead of just one.
* In ''Manga/{{Berserk}}'', when Casca first fights against Adon, she finds herself being driven back by him due to her having a period at the worst possible time. She is saved by Guts, and the next time she goes up against Adon afterwards, she starts to drive him back, telling him that she just wasn't feeling well last time, much to Adon's surprise.
* Characters on ''Manga/DragonBall Z'', whether hero or villain, tend to do this very frequently.
** In their first match, Tien outmatched Goku, easily able to keep up with his speed. After taking a beating, Goku decides to fight seriously. Apparently, he has been holding back during the entire tournament so he won't kill anyone, but decides it's okay to use his full power against Tien since he's very strong. The fight continues with them being more evenly matched with Goku having the advantage.
** During the second Goku/Tien Shinhan match, both are about evenly matched until Goku stops and asks if he can take some of his clothes off. Tien obliges (it's apparently rather hot outside), and thinks nothing of it until Goku's undershirt lands on the floor with a heavy-sounding thud. Cue the weighted-clothing revelation and [[http://www.mangafox.com/manga/dragon_ball/v15/c009/last.html Tien's subsequent humiliation]]. Even funnier, Goku was ''still'' holding back.
** Having reluctantly [[StrangeBedfellows teamed up]] with Goku to stop Raditz, Piccolo gets ready for the fight by taking off his cape, revealing that it's actually weighted training gear. Goku gets a kick out of this -- and takes off ''his'' weighted clothing.
** After taking a hard hit from second-form Frieza, Piccolo ditches his weighted cape and powers up to a higher level. This gives him the advantage until Frieza one-ups him by going to his third form.
** Goku tries this against Nappa, refusing to use the Kaio-ken and handily beats him. Then he tries to kill Gohan and Krillin, forcing Goku's hand.
** Frieza is the franchise's absolute worst offender: One of our heroes finally has Frieza's measure? [[OneWingedAngel He just transforms to a stronger form.]] ''Three times.'' Later on, Goku is seemingly matching Frieza's strongest form - until Frieza reveals he's still not even using ''half'' his power. Goku assumes he's bluffing until Frieza goes up to 50% and starts kicking his ass all over again. Even after Goku turns Super Saiyan, Frieza has one more lengthy power-up sequence left as he goes all the way to 100%.
*** In Frieza's case, it's explained that he has difficulty controlling his true power and the transformations keep his power within manageable levels. This shows in Frieza rapidly burning out when he reaches 100% of his power.
*** Of course, at one point in the fight (after assuming his final form) Frieza ''intentionally'' gives himself a handicap, offering to fight Goku without using his hands, and he actually does for a while. He was likely just showing off, and stops doing it when Goku seems to be fighting better.
*** And he does it ''again'' in ''Anime/DragonBallZResurrectionF''. It ends up Frieza never properly trained because he was such a natural prodigy, and by training for four months he can surpass Goku in raw power.
*** [[spoiler:After Frieza comes back to life, again, for the Tournament of Power he reveals to Goku that, during his time trapped in Hell, he has been focused on mental training. As such not only can he access his Golden Frieza form without burning himself out he can maintain his power at a much stronger rate then before.]]
** Goku vs Majin Vegeta becomes this in hindsight. Vegeta [[DealWithTheDevil sells his soul to Babidi]] in order to get himself a power boost and when he fights Goku, it effectively ends in a draw. After Vegeta performs a HeroicSacrifice to [[SenselessSacrifice try]] to kill Majin Buu, it's revealed later on that Goku had unlocked Super Saiyan 3 and had been holding back against Majin Vegeta all along.
** Played with in the fight between Gotenks and Super Buu. Piccolo assumes Gotenks really IS outmatched, panics, and traps them all in a pocket dimension. Gotenks then reveals that he was only pretending to be losing, and that he could secretly go Super Saiyan 3 all along. He was hiding it because [[InvokedTrope he thought it would be more]] entertaining. He uses his withheld Super Saiyan 3 transformation to rip the fabric of space-time, escape said pocket dimension, and kick Super Buu's ass for five minutes anyway.
** Invoked in ''Anime/DragonBallSuper'' when Goku ends up in a tournament alongside Frost, an alternate version of Frieza from a parallel universe. When Frost claims his third form is his strongest, Goku doesn't buy it and accuses him of keeping a transformation in reserve for later matches. Not only does he ''know'' what Frost's true form would look like, he's doing the same thing himself.
** The tendency to fight this way gives Goku and Pan serious trouble against Haze Shenron. Pan has no problem kicking around this pathetically weak opponent but it turns out that his pollution aura has been sapping their strength, thereby giving him the upper hand. After escaping his area of influence and regaining their strength the pair are able to return and easily destroy him with an energy blast. They should have just done that in the first place.
* Kenshiro tends to do this quite frequently to a worthy opponent in ''Manga/FistOfTheNorthStar''.
* In ''Manga/{{Gintama}}'', Kagura pulls this on [[spoiler:Abuto]]. They seemed a pretty equal match, until he has her pinned to the floor and helpless, but it turns out she [[spoiler: wasn't fighting with her full power; she then goes full-on Yato on him and proceeds to give him a thorough thrashing]].
** Not a conscious reveal so much as a SuperPoweredEvilSide triggered in response to Shinpachi almost being killed by Abuto. Shinpachi actually has to stop Kagura from killing Abuto, knowing that in her right mind she wouldn't want to.
* In ''Anime/{{Gundam 00}}'', Tieria is in control of Gundam Virtue, which is capable of transforming into the ridiculously powerful, androgynously-beautiful Gundam Nadleeh.
** Debateable -- Nadleeh is less capable of inflicting damage than Virtue and only slightly more manouverable; while it has the power to completely shut down certain opponents, it is ''less'' powerful than Virtue against all other foes.
* In ''Anime/YuGiOh5Ds'' Psychic duelist Akiza (Aki Izayoi in the original) has a hair braid that supposedly suppresses her powers (which is basically to make Duel Monsters and magic real); however, this may just be a MagicFeather.
* Ryuho of ''Anime/{{Scryed}}'', when, pressed by Kazuma, he reveals that his Alter, Zetsui, has a level of power previously unknown even to his closest allies.
** It seems to be more of a justified PowerLimiter as their energy is drained a lot faster when using it. Also his allies knew about it, but it was stated that it had not used for the last two years.
* Gou from ''[[Manga/GetterRobo Getter Robo Go]]'' handicaps himself during a shot put event by only using his right hand. When he uses his left hand, he can throw the weight like a baseball.
* Used almost literally in ''Manga/MrFullswing'', where ace pitcher Inukai claims to have been a softball player for most of his time in middle school and throws underhanded pitches with his right hand... until the final batter of the tryout game comes up, and he switches to his natural left handed, baseball pitching style.
* Similar to the ''Mr. Fullswing'' example above, the antagonistic billiards player Ryoji in ''Breakshot'' is narrowly defeated by main character Chinmi in a exhibition match, and it's immediately revealed that Ryoji, who had been using his right hand against Chinmi, is actually left handed and was going easy on him. When they meet again in the finals of the tournament, Ryoji reveals there's more to it than that; He actually ''let'' him win before.
* Played with in ''Manga/HunterXHunter'', in the Greed Island arc, where Killua and Gon train with Biscuit Krüger who looks like their age, but isn't. Not only that but when she fights against an opponent while Killua and Gon aren't around, she turns into a huge muscley beast that is her "real form" and utterly obliterates the opposition. She's quite strong before this, so it isn't so much hiding her strength as it is she thinks the form is really ugly and doesn't want people to see it.
** There is also Netero in the hunter exam, where he challenges [[TheProtagonist the boys]] to a game where they have to snatch a ball from him before sunrise. Netero spends most of the challenge using only his left hand and right leg, in the end they try and succeed in forcing Netero to use the rest of his limbs after they knew for sure that they could chase him for a year and not catch that ball.
* Played straight in ''Manga/{{Shamo}}'', where VillainProtagonist Ryo Narushima spent most of all 5 rounds struggling to fight the heavyweight karate genius before a straight punch literally knocked some sense-inducing flashbacks into him, to which he switches to a southpaw stance, completely shocking the entire crowd.
** It is also used as an explanation of why Ryo turned out the way [[VillainProtagonist he is]]. Yes, folks - [[ASinisterClue he's evil 'cause he's left handed]].
* The entire Negi/Kotaro vs. Rakan/Kage fight in ''Manga/MahouSenseiNegima''. The entire thing consists of the the opponents one-upping each other, to simply ludicrous levels. [[spoiler: Negi does it ''five times'' in a single chapter.]]
** Rakan later combines it with ScrewDestiny. When [[IncrediblyLamePun disarmed]], dislegged, told he's a puppet, and shown that the Princess has [[HypnotizeThePrincess been hypnotized]]. He responds by putting on magical armor arms and legs and getting up for round 2.
*** You know what, just Rakan in general is this trope. [[spoiler: After he was finally defeated by Fate and dissolved by the Code of the Lifemaker, he re-materializes when Fate taunts Negi and then gives Fate a final epic punch and tells Negi to kick his ass before dissolving for real.]]
** Happens also in the final fight of the Mahora Festival Arc. After destroying the main secret weapon of his opponent (and his own equivalent weapon gets destroyed in the meantime as well), Negi declares that now he has an advantage because he can use magic and his opponent cannot. Then suddenly his opponent reveals that she is pretty good at using magic in battle too. Of course, he should have expected this, since [[spoiler:she is his [[KidFromTheFuture descendant from the future]] after all.]]
* In an episode of ''Manga/HikaruNoGo'', a guy named Dake-san is called in by the proprietor of a Go salon to teach a lesson to a kid who's been cheating. He pretends to be a weak player at first, among other things by holding the stones poorly - with his right hand. His moment is when he reveals that he IS left-handed.
* Justified in ''Manga/KatekyoHitmanReborn''. Ryohei only uses his left arm in his fight with Lussuria until he needs to. This is because he was saving the energy in his right arm so he could use his Maximum Canon.
** "Haha, too bad. I've only shown eighty percent of my power so far." "I've only shown half."
* In ''Anime/AngelicLayer'', during Hikaru's fight with Shirahime, Shirahime takes off her kimono, increasing her already-amazing speed and turning the tide of the battle.
* ''Manga/{{Eyeshield 21}}'' football teams tend to do this by not allowing certain players to play until needed, as to make the enemy underestimate them.
* ''Manga/FullmetalAlchemist'':
** While fighting Wrath, Scar reveals that [[spoiler:during the three month break he has tattooed his right arm with his brother's reconstruction transmutation circle getting rid of his weakness that he could only deconstruct using alchemy]].
** Much earlier, Edward fought Slicer/Number 48 a BoxedCrook turned AnimatedArmor who displays his blood seal on the back of his helmet during the fight. Ed then knocks the head off, knowing he couldn't control a body he wasn't connected to, but then it turns out "Slicer" was actually ''two'' {{Serial Killer}}s (brothers), the other of which was put in the same armor, but the seal was on the torso. This is then Lampshaded after Ed beats him as well and he pokes the armor cautiously while asking if there was a third one. The older Slicer brother resignedly says no, it's just the two.
** When Ed fights Kimblee, he manages to screw up one of the half transmutations circles on Kimblee's hands and [[spoiler:knock the Philosopher's Stone out of his hand]] to prevent Kimblee from using any alchemy without wasting time drawing another circle, but [[spoiler:Kimblee had ''another'' stone hidden in his mouth (and had for literally years)]]. [[StuffBlowingUp Explosions ensue]].
** Also, when Sloth gets badly pummeled by the Armstrong siblings, he remarks it's time to "go full throttle":
--->'''Sloth''': "[[spoiler:I am the fastest Homunculus.]]"
** In an extra chapter in the manga "The Military Festival" Ed and Mustang battle it out (or rather, Mustang shoots flames at Ed as Ed runs around dodging). Ed suckers Mustang close enough to rip off the transmutation circle on his glove when Mustang reveals that his left hand (which was in his pocket the whole time) also has a transmuting glove on it. So it's more like I Am Not Right Handed. Later, during Mustang's fight with [[spoiler:Envy]], it tuns out to not be a gag when we see Mustang consistently using his left hand for pinpoint burning and his right hand for big explosions.
* Parodied in ''LightNovel/BakaAndTestSummonTheBeasts'', when Akihisa goes up against Miho Satou, an A class student, Akihisa declares himself to be left-handed, but winds up losing anyway, because it's a fight determined by ''test scores''.
* In ''Manga/ChronoCrusade'', Aion gets badly beaten by Duke Daffau when [[spoiler:Daffau attacks Aion's base, Eden]]. For a moment, it looks like Aion's beaten within an inch of his life--until he reveals that he was holding back the entire time and proceeds start a trap that weakens Daffau and his troops, while activating a secret property in his sword that allows him to [[GoodThingYouCanHeal heal incredibly quickly]].
* In one of the Early rounds of the [=DoD=] tournament of ''Manga/KenichiTheMightiestDisciple'', Takeda claims he can handle an opponent by himself. Cue him getting whupped. He then states loudly that he's going to have to take this seriously, whereupon he takes off his shirt, revealing that he was wearing a full body spring retainer thing. This being a tournament where people have been known to die, everyone, including the announcer, declares him insane.
* The Evangelions of ''Anime/NeonGenesisEvangelion'' have large electrical plugs attached to their back, but [[spoiler:when Eva-01 goes berserk during the Zeruel battle it doesn't need power at all]] , have armor which doesn't protect them as much as it restrains them, even being referred to as "binders".[[spoiler: After the berserk Eva-01 mutilates and "awakens" after ''eating'' Zeruel it pops off its binders by ''flexing its muscles'', which scares Nerv enough to put it under quarantine.]]
** In general, when the Evas go berserk, they tend to do things that didn't seem within their capabilities beforehand (regenerating arms, taking damage that would have destroyed them earlier, and in Rebuild, [[spoiler: shooting eye beams and triggering new impacts ''by themselves''!]]).
* ''LightNovel/{{Katanagatari}}'' has a particularly crazy example (warning: spoils an awesome twist). [[spoiler: Despite being physically weak and ill, Nanami starts the series able to easily defeat her brother, who defeated the official Greatest Swordsman in Japan. Turns out, she can also [[PowerCopying copy any skill]] she sees, including super-strength, spontaneous claw growth, and walking on water. Then it turns out that she has inhuman resilience and can't die no matter how sick or poisoned she becomes. ''Then'' it turns out she's acquired one of the Deviant Blades, which cures her weakness and low energy. After all that, she still counts as WillfullyWeak! She uses others' skills because her own instinctive combat skills are utterly perfect.]]
** Also Shichika in the final episode, once he [[spoiler:doesn't need to worry about breaking the Deviant Swords or getting hurt any more, unleashes his full power on the new wielders and effortlessly curb-stomps them.]]
* Alice L. Malvin of ''Anime/PumpkinScissors'' pulls this bit in the final duel of the series when she switches hands mid-fight.
* ''Anime/StarDriver'' episode 3 features a mecha sword fight. At first, Takuto's opponent is kicking his ass...until [[spoiler:he pulls out [[DualWielding a second sword]]]]. Eventually, we learn that Takuto has been doing this ''the entire time''. What looks like NewPowersAsThePlotDemands is actually nothing of the sort. He's been trained to be a Driver since birth, and knew nearly everything his mech was capable of. Since he needed every advantage he could get, he fought his opponents using the minimum amount of skill and abilities, and whenever they reached the point where he was in trouble, he revealed [[IAmNotLeftHanded his next trick]].
** And then comes another IAmNotLeftHanded moment after the fight itself: [[spoiler:"How does it feel to use a cybercasket despite having a mark?"]]
* In combat Lind of ''Manga/AhMyGoddess'' wields a massive Lochaber axe against opponents. One such opponent, believing it to be her only method of attack due to not utilizing any other power, shattered it in an attempt to cripple her. A bystander snidely commented that the axe was Lind's way of being polite; commence massive kicking of bad guy butt.
** She also pulled this on Hild in an earlier arc. The latter thought that she couldn't fight since she no longer had her angel, Lind ([[spoiler: and Keiichi's]]) reply can be summed up as [[spoiler: [[IAmNotLeftHanded I Am Not Single Angeled]].]]
* In chapter 240 of ''Manga/FairyTail'', Ultear reveals [[spoiler:that she can use Ice Maker Magic like her mother Ur]] when Gray finds a way to counter her Time Arc magic.
* In the first [[AllThereInTheManual Drama CD]] of ''Anime/TigerAndBunny'' -- set back in Kotetsu's high school days -- Kotetsu gets into a match with Antonio (who has NighInvulnerability as his [[DifferentlyPoweredIndividuals NEXT]] power) and manages to fight him to a standstill... While entirely unpowered. When he ditches the fight to save someone trapped in a burning factory and activates his own NEXT abilities, Antonio is surprised to say the least.
* Yaoi/baseball manga ''Perfect XXX''. After pitching a few perfect games with his left hand, an opposing hitter actually hits a home run off of one of Kenshiro's pitches in the first inning, so the the next inning Kenshiro surprises everyone (well everyone on the other team and Ayato) by pitching with his right hand. [[spoiler: Apparently the whole reason Kenshiro even used his left hand for everything (eating, writing, etc.) was to try to score points with Ayato, because Ayato said "Lefties are cool".]]
* In ''Manga/{{Claymore}}'', Teresa of the Faint Smile easily defeats the #2, #3, #4, and #5 without releasing any of her power. When the #2, Priscilla, unleashes 80% of her power and starts giving her trouble, Teresa simply releases 10% and easily defeats her again.
* ''Anime/MobileSuitGundamWing'' has the reverse. During their duel where Wufei is struggling to match him, Trieze points out that Wufei could have torn him in half with his extendable dragon arms minutes ago and called it a day. Wufei says he wants to defeat Treize blade to blade (which is odd since Wufei is using a double ended spear at least twice as long as Trieze's sword giving him a massive reach advantage anyway). Trieze has to end up throwing the fight for Wufei to win, pissing Wufei off, and causing mental anguish that he didn't really beat him to haunt him for the next year.
* In ''Manga/OnePiece'', during his battle with Blueno, Luffy realizes that he won't able to win as he's fighting currently, so he kicks in Second Gear. Blueno is immediately [[CurbStompBattle Curb-Stomped]].
** The same thing happens later when Luffy fights Boa Sandersonia and Boa Marigold, whose Haki gives them the ability to predict his attacks and the strength to guard against them. Then Luffy kicks in Gear Second. Their strength is no longer adequate to guard against his attacks, and while they can still predict his movements, he's too fast for them to keep up with them.
** Same thing happens with [[spoiler:Gear Fourth]] in Luffy's fight with Doflamingo - hovewer, after spending some time [[CurbStompBattle getting punched across the town]], Doflamingo [[spoiler:activates his awakening power]], equalizing chances.
* In Manga/PandoraHearts, [[spoiler: Vincent pulls the reveal that [[InstantSedation the Doormouse]] is not his only chain.]]
* In ''Anime/{{Beyblade}}'' Michael of the American team is introduced as incredibly overpowered, with a left-handed shot called [[NamesToRunAwayFromReallyFast Cannonball Attack]] that has knocked out any opposing beyblades. When Max manages to overpower him in the second set of their match, Michael reveals it's his ''off-hand'', and the right-handed is extremely more powerful. [[spoiler: [[CrowningMomentOfAwesome Max still wins]].]]
* ''Manga/OnePunchMan'': Saitama takes this trope leaps and bounds beyond most. Most of the time, every threat he finds, he can trounce without putting an ounce of effort. And then the really powerful villains show up, start thrashing the entire league of superheroes, and he decides he'll get slightly serious about it. And ''that'' is when the near-apocalyptic punches start coming out. Woe betide anyone he actually has to punch ''twice''.
* Characters from ''Manga/{{Toriko}}'' tend to use that trope a lot.
** In his first battle with Starjun, Toriko powered up mid-battle [[CurbStompBattle and wiped the floor]] his robotic avatar. Whoever, turned out that Starjun immensely stronger than Toriko and lost only because his super-powered robot body was ''slowing him down''.
** Later in the story, Toriko pulled one on Starjun. After he used all his strongest attacks on him, which barely did any damage. It looked like he doesn't have a chance, until he revealed new battle technique, that basically allowed him to [[spoiler:[[OneHitKill turn all his attacks into one-hit kills]] and [[GameBreaker make up new moves as battle go]].]] It looked like Starjun doesn't stand a chance, until he [[spoiler:[[PowerCopying managed to learn this technique, just by watching him]].]]
** In one of the earlier fights Coco and Toriko got into really difficult fight with the Devil Serpent - particularly nasty giant snake. After battle was over Toriko complained, that he wouldn't be able to eat it, since Coco poisoned it. Coco replied that he knew, that Toriko would want to eat it and purposely used a weaker poison, that dissolves when exposed to heat and if he had used actually strong thing, battle would be much easier.
** Sunny used this twice - in the fight with Cedre he pretended to run out of stamina in order to get him in the range of attack and in the fight with Tommyrod he struggled to [[spoiler:remotely control strands of hair, which was previously cut off by Tommyrod's bugs, accidentally giving the impression, that he can't control his satan hair, while in reality he already had full control over it.]]
** Tommyrod himself looks constantly wears [[PowerLimiter bracelets, which prevents his muscles from expanding]], considerably weaken him and make him look frail [[WorldofMuscleMen (especially by Toriko standarts)]]. If he deems his enemy " worthy ", he takes them off, revealing his real strength enormous muscles.
** Both Jirou and Mansam has special [[PowerLimiter seals]], which prevents them from using their full power, because they considered to dangerous. They take off their seals and using they full power only in most dire situations.
** Monkey king Bambina is embodiement of this trope. Not only he is never fight seriously ([[spoiler:he just trying to dance, but due to his immense strength and speed, his partners end up ripped to shreds]]), but his body constantly [[spoiler:covered in [[PowerLimiter tight layer of skin and fur, that restrains and weakens him]], and his true power gets unleashed only after he breaks out of it.]]
* ''Manga/RosarioToVampire'':
** During the Newspaper Club's initial fight with Kuyou in his initial monster form, they manage to do quite well against him... until he breaks out his [[BishonenLine Ultimate Battle Form]] and hands them their asses.
** After battling Moka and Tsukune for some time, Hokuto reveals he was wearing a PowerLimiter, takes it off, and goes OneWingedAngel on their asses.
* Played for drama in ''Manga/RurouniKenshin'' by Hiko Seijuro, who wears "a white cloak set with springs opposing the muscles and 10 kan (80 lbs) of shoulder-weights. It's been used by those who hold the name of Hiko Seijuro to restrain the inheritor of the Hiten Mitsurugi's power in times of peace." He takes the cloak off in preparation to [[spoiler: attack with the lethal and exacting Kuzu Ryu Sen, forcing Kenshin to master the succession technique or die trying]].
* In ''LightNovel/FateZero'', Lancer fights using a long and short spear. During his first duel with Saber, his Master orders him to get serious, so he puts the short spear on the ground, giving the impression that it is an ordinary weapon. Eventually, Saber gets overconfident, parries his long spear, and lunges. At this point, Lancer suddenly kicks his short spear into his hand and stabs her. Turns out it was special after all, as it gives a WoundThatWillNotHeal.
* Happens multiple times in ''Manga/SaintSeiya'' during the Twelve Temples Arc and the lead-up. Most of the times is the Gold Saints that, for a reason or the other, are holding back, but the final (and most magnificent) it's [[spoiler:''Shun'' who reveals he had been on the level of the Gold Saints since the start of the series (and indeed, the moment he goes all-out he ''kills'' one after all his previous blows having caused little damage out of an attempt of simply force his surrender), [[MartialPacifist he just didn't want to kill his opponents unless he had to]]-and at that moment he ''had'']].
* ''Manga/{{Bleach}}'': Most battles have this and/or HeroicSecondWind. It's possible to predict who will win a close fight based on who powers up first.
** 11th squad Captain [[BloodKnight Kenpachi]] used to braid bells into his hair so his opponents could hear him coming. By wearing an [[EyepatchOfPower eyepatch]] over a fully functional eye not only impedes his vision but is composed of power-sucking creatures that keeps his [[PowerLimiter power level down]]. He also insists on using his sword one-handed to weaken the force of his blows. When he does finally use his sword two-handed (and with his eyepatch removed), the power that explodes from his cut is enormous. [[spoiler:Even when Kenpachi stops physically holding back, he's still subconsciously holding back; this quirk is only resolve through TrainingFromHell.]]
** Kenpachi's third seat, [[BaldOfAwesome Ikkaku]] [[BloodKnight Madarame]] likes to be straight-forward in battle. His skills, however, are anything but.
*** He employs a predictable routine of attacking with his sword in his right hand and parrying with his scabbard in his left. Then, just as his opponent has become comfortable with this style, he'll switch his sword and scabbard ''in mid-strike'', reversing his attacks and parries and thus revealing he's ambidextrous.
*** His shikai manifests as a spear. Except it's not. It's really a three-section staff and it can slip between spear and staff at any stage, completely catching his opponents off guard and making his attacks unpredictable.
*** He greatest secret is that he also possesses bankai. He keeps this secret out of fear that he'd be forced to leave the 11th division and become a captain of another squad. He'll even throw a fight if he can't get away with using it in secret. Iba has hinted that EverybodyKnewAlready.
** Yumichika's zanpakutou initially transforms into a khopesh-shaped weapon. Then he reveals it can actually transform into a four-bladed sickle-sword, although it doesn't do anything more than give his opponents very nasty wounds. Finally, Yumichika reveals this is actually a fake shikai and his real shikai is arguably one of the most powerful zanpakutou in the entire manga, being able to [[EnergyAbsorption absorb the life energy]] from anything it captures and then use that absorbed energy to [[VampiricDraining heal Yumichika's wounds]]. The only two times he's used it, he's [[CurbStompBattle one-shotted]] both opponents. The only reason he doesn't thrash people right and left with it is because it's a [[MagicKnight kidou-type]] zanpakutou which is taboo in the [[BloodKnight 11th squad]]. He'd therefore [[HonourBeforeReason rather die]] than have his squad learn the truth.
** Aizen deprives Yamamoto of his zanpakutou because of its reputation for being the most powerful offensive zanpakutou ''ever''. Yamamoto promptly reveals Aizen's error by unleashing hell with his bare fists and some of the story's most powerful kidou attacks.
** Nnoitra's released form reveals four arms which even Kenpachi struggles to fight against. And then Nnoitra reveals he doesn't have four arms, after all. ''He has six.''
** Kyōraku subverts this. His shikai is a tricky set of weaponized children's games that trap both him and his opponent in the rules of the game until one or the other is dead. The three games his reveals become something of a pattern for him, one that Starrk gets used to. Then he reveals he had a fourth game all along, one that allows him to ''ambush strike through shadows''.
** When Uryuu and Mayuri fight, Mayuri believes he's resolved the fight quite quickly by paralysing Uryuu's body with poison. Uryuu reveals he possesses a Quincy technique that allows him to fight normally ''even when his limbs are otherwise completely paralysed''.
** When fighting against Gatanbainne, Sado reveals the enormously powerful [[WhenAllYouHaveIsAHammer right arm]] he's been fighting with throughout the manga is actually a defensive, shielding power. His real attack force is located in his left arm and is much more powerful than his right arm.
** When Soifon and Yoruichi fight, Soifon thinks she has the upper hand and proudly displays her ultimate technique which she's only just invented and mastered and hasn't even had time to name yet... then Yoruichi reveals that she knows all about the technique. She had developed, mastered, and named the technique decades ago and Soifon has in fact still got a long way to go before she comes even close to genuinely mastering the technique.
** Gin Ichimaru's bankai extends his sword to 13 kilometers length, and he demonstrates its power by slicing buildings in half with one long circular swing. But he then reveals that the true strength of the weapon is not its length, but how fast it can extend and retract (roughly 500 times the speed of sound), essentially acting as a sword-shaped railgun/machine gun. [[spoiler:And then, at a critical moment, he reveals it's not quite that long or fast. The true danger in the blade is that when it extends and retracts, it dissolves into a metallic powder that is left behind in the wounds it causes. The powder dissolves into a deadly, fast-acting, cell-destroying toxin]].
** When Ulquiorra and Ichigo have their final battle, the former finally decides the latter is strong enough to warrant activating his release, which he uses to completely curbstomp our hero. Then, when Ichigo refuses to [[{{Determinator}} give up despite the clear power gap]], he decides to show him his greatest secret: He has not one, but ''two'' releases, and is the only Arrancar to ever succeed in doing so. He then proceeds to open an even greater can of [[CurbstompBattle whoopass]] on Ichigo.

[[folder:Comic Books]]
* DC Comics icon Franchise/{{Superman}} is prominently known for holding back all the time to avoid one-shotting his opponents' heads off as well as general collateral damage. When the gloves are off, however, fights tend to end quickly. Issue 669 explores this in depth (a flashback to his rookie years, when he had to be extra careful because humans are squishy). For what happens when Superman stops holding back, see WorldOfCardboardSpeech.
** In ''ComicBook/FinalCrisis'', Superman builds The Miracle Machine, which can grant one wish. [[BigBad Mandrakk]] arrives and says he did that for nothing, as he has no power source great enough to activate it. Superman [[spoiler: unleashes the stored yellow sunlight within his own body, turning it on. He wishes for... [[EarnYourHappyEnding a happy ending]]. This simply ensures that the good guys will win this battle.]]
*** Likewise, Mr. Tawky Tawny is involved in this crisis and the Tigerman leader he fights - Kalibak, the son of ''Darkseid'' - learns the hard way that while he may look like a wimp in his tweed business suit and bowtie, he is still a mighty ''tiger!''
* ''Comicbook/{{Supergirl}}'':
** When DC brought Kara Zor-El back after her death in ''Comicbook/CrisisOnInfiniteEarths'', it was rumoured that she was more powerful than Superman. Then Superman proved that his cousin was not more powerful. She ''seemed'' more powerful because she hadn't learned yet how to hold back, unlike him, who is always holding back.
** In ''Comicbook/RedDaughterOfKrypton'', one dozen of Green and Red Lanterns manage to restrain a mad Supergirl. Afterwards Kara reveals that she was holding back because she was scared of killing them all if she let loose. Guy believes her.
* Competitor Marvel's flagship character Franchise/SpiderMan does something similar to Superman, too, albeit at a much lower level; after all, Spidey collars ordinary crooks almost as often as he clashes with super-villains (one of which actually has human-level toughness), and using his full strength to punch out a non-superpowered bank robber would end up rather messy. Often, he avoids this simply by webbing up normal guys rather than fighting them directly. A rare example of his actually taking the kid-gloves off occurred In ''ComicBook/OneMoreDay'' when he was goaded by ''ComicBook/TheKingpin'', someone who had always been considered a worthy match for him before -- but not now. With nothing left to lose, [[CurbStompBattle Spidey wiped the floor with him]], letting every witness (and there were ''plenty'') know he could have done that ''any'' time he had wanted.
* In the "What If?" ComicBook/CivilWar special, Henry Gyrich creates an army of Thor clones to enforce registration. Reed Richards notes that Thor once told him that no matter how powerful a mortal is, he will only ever use a third of his strength for fear of killing them. The clones, of course, have no such restraint.
* When the ''real'' Thor comes back after Civil War, he confronts Tony Stark over what he did - with his hammer. When the lightning bolts start flying, Tony blasts him - to no effect. He tries the "old school" approach, and Thor sends him flying and near-cripples his armor with one hit. He says that Thor must have been working out, in shock at how hard he was hit. Thor replies that the only difference this time is that he isn't holding back.
* Comicbook/{{Empowered}} turns this into a CrowningMomentOfAwesome in Vol. 4: [[spoiler: Emp confronts Fleshmaster, a former hero who'd turned his powers against everyone at Capes' award banquet. Emp's suit had been [[ClothingDamage shredded down to gloves]], rendering her naked and powerless. Fleshmaster gives her a quick NotSoDifferent speech (They were both considered the {{Butt Monkey}}s of the hero community) and offers to spare Ninjette and Thug Boy... if Emp will give him a blow job. Emp goes "ShutUpHannibal"... before revealing that she could turn her suit invisible at will. Cue CurbStompBattle.]]
** Syndablokk also does this earlier, when he and Emp were getting thoroughly thrashed by a villain, he shows that he has the ability to manipulate concrete, masonry and pavement, but doesn't use it much because it could cause a lot of collateral damage and the aftereffects tend to linger.
* Near the end run of ComicBook/BirdsOfPrey, the team moves their headquarters from Metropolis to Platinum Flats, which just happens to be the next town over from where former member Black Canary is now living. Of course, it ultimately results in a LetsYouAndHimFight between Black Canary and current Bird of Prey member Manhunter. As they battle Manhunter prattles about her recent fights against other superheroes, explaining the successes she has had in sparring matches against the likes of Wonder Woman, and is happy to finally have a chance to see how she compares against such a famed martial artist as the Canary. However, a while into the fight she questions the Canary as to why she has not used her signature Canary Cry, to which the Canary responds that she "is trying really hard not to put [the Manhunter] in the hospital."
* In the ''[[ComicBook/TheFlash Flash: Rebirth]]'' series (pictured), Superman is chasing after Barry Allen, when Superman begins talking about the races they've done in the past. Barry responds with "Those were for charity, Clark," and immediately speeds off, leaving Superman dumbfounded and far, far behind.
** This is a retcon. Superman's speed used to be a match for Barry's but it had been retconned to be slower in the 25 years since their last race.
* ''ComicBook/XMen'': ComicBook/{{Cyclops}}'s glasses / goggles don't just let him control his powers, they also [[PowerLimiter limit]] them. If he's willing to take his visor off for even a few seconds, you're in trouble.
** In ''Astonishing X-Men'', the team are confronted by a Sentinel. They line up and talk tactics but Cyclops is in no mood for such things -- he removes his glasses, and utterly ''eradicates'' the Sentinel from existence -- as well as about a mile of forest around. Later in the same run he had his powers psychically de-activated by Emma Frost and had been captured and tortured by an alien warlord. When he finally tells the warlord that the X-Men's secret weapon "Leviathan", was completely fictional (thus throwing out any reason to keep him alive), he starts laughing. The warlord attacks him, demanding to know what else he's been lying about. [[spoiler: Then [[http://1.bp.blogspot.com/_Gd8NBIma-zo/RzSgt3KLuhI/AAAAAAAABm8/hjnXT6PbLlA/s1600-h/scottLies1.jpg with the villain right up in his face,]] [[http://2.bp.blogspot.com/_Gd8NBIma-zo/RzSguHKLuiI/AAAAAAAABnE/VsI5SKYySOM/s1600-h/scottLies2.jpg Cyclops reactivates his eyebeams and blasts the villain, leaving a massive hole in the building.]]]]
** Another instance of this is in the first volume of ''ComicBook/UltimateXMen''. Cyclops is being restrained by a Sentinel because it has figured out that he operates his optic blasts by pressing a button on the side of his visor. Scott then reveals that he can also do it by snapping his fingers.
* One issue of ''ComicBook/TheMightyThor'' had Hercules telling a pompous tale about a fight with Thor. He was just getting to the point in his story of beating the daylights out of the thunder god when he learned that one of the young listeners was a ''serious'' Thor fan. So Hercules abruptly changed the ending to reveal that Thor had been holding back all along, and punched Hercules across the sky. "I landed in a place the gods forgot: New Jersey!"
* The last fight in ''ComicBook/DoctorStrange: The Oath'' is a fistfight between Strange and Nicodemus West, who also knows magic but has deployed some anti-magic [[AppliedPhlebotinum phlebotinum]], expecting he can take Strange in a fair fight. Doc lets West pummel him for a minute or two (and waste his energy) before breaking out the KungFuWizard skills.
* Played with in issue four of ''[[ComicBook/LokiAgentOfAsgard Loki: Agent of Asgard]]''.
-->[[spoiler: '''Sigurd]]:''' ...I've got a confession to make. I'm actually left-handed. ''[switches his sword to the other hand]''\\
'''Loki:''' Oh? Then I, too, have a confession to make -- ''[switches HIS sword to the other hand]'' I've seen that same movie--''eep!''\\
''[[[spoiler:Sigurd]] slices off a little of Loki's hair and [[spoiler:kicks him out of a window]]]''\\
[[spoiler:'''Sigurd:''' Ha! Made you look--]]
* During ''ComicBook/AgeOfApocalypse'', Wolverine, here called Weapon X, lost his left hand to Cyclops and it seemed that he had also lost his claws on that hand, too. However, during the final confrontation with Donald Pierce, Weapon X revealed that he had actually ''retracted'' his claws before he lost his hand, and promptly gutted Pierce with them.
* During one ComicBook/MickeyMouseComicUniverse story set in the middle ages Mickey and Pete are having a sword fight, and seeing himself on the verge of losing Pete actually quotes the TropeNamer and switches hand, saying he had been fighting left-handed for years because otherwise it would have been too easy. Then Mickey ''completes the quote'' and switches hand too, before winning the duel.
* In ''ComicBook/DetectiveComicsRebirth'', Batman confronta Lady Shiva, and points out that he's beaten her before (due to her status as an AdaptationalWimp post-Flashpoint). She responds that she had been simply playing a role, and no longer has a reason to pretend to be weak. She then proceeds to wipe the floor with him.

[[folder:Comic Strips]]
* In one ''ComicStrip/{{Garfield}}'' strip, Garfield harasses a leashed dog.
-->'''Garfield:''' Dogs are stupid. ''[[[BullyingADragon slaps dog repeatedly]]]'' With bad breath.\\
''[dog effortlessly snaps his collar]''\\
'''Garfield:''' But I love them anyway.

[[folder:Fan Works]]
* ''Fanfic/ChildOfTheStorm'':
** Thor gets thoroughly sick of the HYDRA distraction ''du jour'' -- a necromantically reanimated kraken said to ''dwarf'' a Chitauri Leviathan which has been shrugging off everything the Avengers have been throwing at it, even Loki turning into a serpent the size of an apartment building -- and draws in so much power from Earth's magnetosphere that it prompts [[spoiler:Magneto]] to briefly investigate, before ''vaporizing it'' in a single shot.
** In a variation on this trope and EleventhHourSuperpower, [[spoiler: Jean Grey]] is pointedly informed by Doctor Strange just how powerful she really is.
* In the Harry Potter fanfic "[[http://www.potionsandsnitches.net/fanfiction/viewstory.php?sid=2489 Burnt]]", Harry used his crippled appearance to his full advantage when he was on the street, and a bit when he's at Hogwarts. He is more than capable of defending himself and could take on any student in his year.
* Rikuto in ''FanFic/{{Pokeumans}}'' admits to Brandon that if he had used his ''full'' power, [[DangerousForbiddenTechnique he would probably have killed him]]. So in this case, he should be grateful he pretended to be left-handed.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanfics:
** From ''Fanfic/SlyWitsParadise'', in chapter 21, Celestia and Luna have an Oh Crap moment when the dragon they are fighting turned out to be a magic user.
** A textbook example happens in ''FanFic/RainboomsAndRoyalty'' when Twilight tries to stop Blackened Armor (her brother who's been corrupted by Nightmare Moon). He mocks her, saying that he remembers everything from his old self and knows that he always won whenever they duelled in the past. Unfortunately for him, he doesn't know that Twilight has been holding back ever since the traumatic day she gained her cutie mark and her power awakened, deliberately keeping her strength down for fear of hurting others. He also doesn't know that she's recently been having an inspirational talk with Rainbow Dash and Applejack, convincing her to trust her magic power and not fear it. She even cites Superman's "world of cardboard speech" before letting loose on the villain.
** In ''[[http://www.fimfiction.net/story/283295/to-dethrone-a-princess To Dethrone a Princess]]'', it turns out Celestia is doing this. The story implies her regalia is actually a PowerLimiter, and without it her physical strength is so immense she leaves craters in the ground by ''walking''. She only takes it off when a rebellion cuts her off from her magic, and proceeds to deliver a CurbStompBattle.
** Something similar occurs in Book II of ''Fanfic/TheElementsOfFriendship''. When Discord first escapes his prison, Celestia confronts him directly, ditching the regalia that worked to keep her magic in check, as she naturally gives off the same amount of solar radiation as a star; for this fight, she actively channels it.
** ''Fanfic/PonyPOVSeries'':
*** Thunderchild hides the fact that unlike a regular Pegasus, he doesn't need a cloud to fire lightning due to being a Gifted Pegasus.
*** The Princesses are ''constantly'' doing this, as their true cosmic power would be rather destructive if fully unleashed. For reference: Celestia is fully capable of using a solar flare to wipe out a planet if she wanted to.
* [[Series/BuffyTheVampireSlayer Xander]] (who's gained [[Anime/DragonBallZ Trunks]] abilities) and Comicbook/{{Superman}} exchange these in ''[[https://www.fanfiction.net/s/10727834/1/The-World-s-End The World's End]]''. While Xander handles Wonder Woman without much trouble, Superman forces him to go first Super Saiyan then Super Saiyan 2 while each of Xander's transformations cause Superman to hold back less. Once Xander hits Super Saiyan 2, Superman stops holding back entirely. Then Xander manages to awaken the [[Franchise/TheLegendOfZelda Triforce of Power]], which both unlocks Super Saiyan 3 and gives Xander a magic sword (which Superman isn't immune to).
* In the Italian remake of ''Fanfic/BattleFantasiaProject'' turns out [[Franchise/SailorMoon Sailor Venus]] had been consciously holding back for the whole anime out of fear of being rejected by the other Sailor Senshi (as her friends in middle school had done when she had started dedicating herself to her duty as Sailor Venus). She explains it after her reaction to returning to life after Galaxia surrender and redemption and, before learning what had happened, decided to stop holding back and ''nearly killed [[WorldsStrongestWoman Galaxia]]'' (in fact the only reason she doesn't is that Artemis tells her what happened right before she can snap Galaxia's neck).
* In ''Fanfic/ShinobiOfTheHighSeas'', during the fight at Ennies Lobby, Naruto reveals that his headband is a PowerLimiter, complete with a WorldOfCardboardSpeech. He then removes it and proceeds to [[spoiler: kick the crap out of one of the [=CP9=], destroy two-thirds of the Buster Call fleet, one-shot a Vice Admiral (who was using Armament Haki), and fight Admiral Aokiji to a stalemate.]]
* In ''[[https://www.fanfiction.net/s/5237318/1/Crush Crush]]'', Xander pretends to have [[ExtraOredinary powers over magnetism]] to make people underestimate him since he's actually a GravityMaster. This becomes important later when he's captured by a government agency with a TailorMadePrison.
* ''Fanfic/RosarioVampireBrightestDarkness Act III'': In chapters 41 and 42, the gang (minus Tsukune) is doing relatively well against Kuyou, and Rason and Ahakon remark that the fight is relatively easy and that Kuyou is a joke; however, Kurumu and Moka, who have faced Kuyou before, quickly inform them that the only reason they've been doing so well in the fight thus far is because Kuyou hasn't even been trying. Sure enough, Kuyou goes OneWingedAngel soon after Moka says this and makes short work of everyone... until Tsukune reenters the fray and annihilates him.
* In ''[[https://www.fanfiction.net/s/11502532/4/Breath-of-the-Inferno Breath of the Inferno]]'',= when Daphne responds to Harry's insistence she would've been dead weight against Voldemort, she reminds Harry he never won a duel against her. Harry promptly [[FlashStep Flash Steps]] in front of her, holding her by the throat. He then reiterates that he never won a ''duel''; they've never actually ''fought''. If Harry didn't limit himself to casting spells, their duels would be pointless as he'd crush her easily. However he needs to be better with magic, and he wants her to get better period. Harry proves his point during the summer by having a five on one match with his friends and beating all of them.
* Applies to all of the four, really, in ''Fanfic/TheKeysStandAlone'', but especially to Paul (who, ironically, is left-handed in [[Music/PaulMcCartney Real Life]]) and George, both of whom have many more abilities than anyone could possibly guess—even themselves!—and who are entirely unwilling to tell outsiders about them until it becomes necessary to actually use them.
* ''Fanfic/AgesOfShadow'':
** At one point, [[FakeUltimateHero Maximus Domino]] conjures up [[FallenHero Jade]] in way that reduces her to a quarter of her regular strength. At first, this looks like it's allowing him the edge to actually hurt her, only for her to reveal that [[PhysicalGod she's so powerful]] that even her reduced strength is far beyond his. She just faked her injuries [[ItAmusedMe as a sick joke]].
** During the FinalBattle, [[spoiler: Jade also reveals that the ExactWords of the rules for the Yade Khan game allow her to interfere and declare the winner. She just never has before because VictoryIsBoring.]]
* ''Fanfic/FatesCollide'': Oda Nobunaga starts her fight with Weiss Schnee with just her sword. When Weiss disarms her and thinks she's won, Nobunaga summons her multitude of guns.

[[folder:Films -- Live-Action]]
* ''Film/ThePrincessBride'': The same trope naming instance occurs in the film as in the book; a swordsman switching to his dominant hand to gain an advantage. Unfortunately for him, in both iterations it then turns out that his opponent is not left handed either and promptly regains the upper hand.
* ''Film/{{Zatoichi}}'' (the 2003 film) subverts this: [[spoiler: as he is killing the last two Yakuza members, Zatōichi opens his eyes and the Yakuza boss assumed he could really see. In the very last scene of the movie, he trips over a rock and a voice over says "Even with my eyes open, I still can't see a thing."]]
* Subverted in the ''Franchise/{{Rocky}}'' series. Neither Rocky nor [[Creator/SylvesterStallone Stallone]] are left-handed, but throughout the movies he fights south-paw by preference. In fact, a substantial part of his training for the rematch against Apollo Creed in ''Film/RockyII'' centered on Rocky learning to fight right-handed, and switching to using his left at a crucial point in the fight to devastating effect. Rocky "is not left-handed", but unlike these other examples he is a distinctly superior fighter when favoring his off-hand.
* A classic example from ''Film/QuigleyDownUnder''. BigBad and QuickDraw specialist Marston finally captures FriendlySniper Matthew Quigley, (who has refused a pistol every time one was offered to him in the movie, saying "I never had much use for them") and decides to kill Quigley in a Western-style shootout:
-->'''Marston:''' I seem to remember you're not too familiar with Colonel Colt's revolver, so this will be your first lesson.\\
''[Marston continues to prattle smugly while setting up a ShowdownAtHighNoon]''\\
''[Quigley shoots Marston and his two henchmen before they can react]''\\
'''Quigley:''' I said I never had much use for one. [[YouDidntAsk Never said I didn't know how to use it.]]
* The movie ''Film/IRobot'' features a fight between Will Smith's character, Del Spooner, and an NS-5 robot that's actually trying to kill him (as opposed to the fight with Sonny, earlier in the movie). Spooner hits the robot with a metal pipe once or twice, which the robot shrugs off, and it acquires possession of the weapon. After successfully dodging the robot's first swing, the robot's second and third swings are blocked by Spooner's left arm -- and on the second impact, [[spoiler:we see part of the inside of the arm exposed, revealing that Spooner's left arm is, in fact, mechanical. (Which -- when the robot looks surprised, or as surprised as a robot can be -- he acknowledges with an almost-apologetic "Yeah.") He connects with a hard punch and a leg sweep using that arm, and tries to punch the robot while it's on the ground -- only to miss, and have his fist go ''through'' the asphalt.]]
* [[Creator/SeanConnery Lt Col Alan Caldwell]], in ''Film/ThePresidio'':
-->'''Lt. Col. Alan Caldwell:''' Now, are you sure you want to have a fight? Because I'm only gonna use my thumb.\\
'''Bully in Bar:''' Thumb?\\
'''Lt. Col. Alan Caldwell:''' My right thumb. Left one's much too powerful for you.
* In ''Film/{{Beerfest}}'', the heroes pretend to be more drunk than they really are to trick the Germans into making a steep bet. Todd, however, really ''is'' that drunk, having been forced to use his "drunken recall" earlier.
* In ''Film/ALeagueOfTheirOwn'', the "ugly" girl, Marla Hooch, has a moment like this during her batting demonstration for Ernie Capadino (Jon Lovitz). After several good hits, Marla's father says, "Okay, Marla, now hit lefty," which causes all the guys in the field to groan in anticipation. She had been batting right-handed, but was a switch-hitting natural left-hander. She hits a towering home run, and gets signed for the new league.
* In ''Film/TronLegacy'', [[spoiler:Sam fights his way to where his [[MacGuffin father's identity disc]] is being held. He gets cornered by [[TheDragon Rinzler]] escorting a [[BadassInDistress captive Quorra]], who had previously trounced Sam using [[DualWielding dual]] [[DeadlyDisc disc weapons]]. Rinzler doesn't account for the fact that Sam has two disks on his person now too when he and Sam square off. The surprise second disk careening at his head, combined with [[ActionGirl Quorra]] using that as a distraction to kickbox him (as her hands were bound), is too much for even Rinzler, and he's left hanging... literally.]]
* In ''Film/UncommonValor'', Scott has finally had enough of the much larger Sailor and says he thinks he can teach "an undisciplined brawler" like Sailor a lesson. The huge, lumbering Sailor rushes Scott a few times only to be knocked on his butt by Scott's martial arts skills. Tiring of this, Sailor says to Scott, "Usin' that Oriental martial bullshit on me's gonna get real expensive," assumes a real fighting stance, and uses his own kung fu skill, which turns out to be superior to Scott's, to treat Scott to "the whole can of whoop-ass."
* A variation occurs in ''Film/TheQuickAndTheDead''. [[spoiler:Ace Hanlon, the big bloater, claims to have two good shooting hands. In his match against Herod, first it turns out that [[ConfrontingYourImposter at least some]] [[MilesGloriosus (probably all) of his war stories were fake]], and Herod proceeds to shoot Ace in his right hand. Herod offers to take the next shot with his left hand, because unlike Ace, Herod really can aim well with both hands. Naturally, this story doesn't end well for Ace.]]
* In ''Film/BackToTheFuturePartIII'', a gun salesman is trying to teach Marty how to shoot, to demonstrate the Colt Peacemaker, and laughs at Marty's terrible shot. However, turns out Marty is not left handed, he switches to his good hand... It might be worth noting that the salesman seems to deliberately thrust the gun into Marty's left hand. Marty does try to switch hands, but the salesman stops him. As noted on other pages concerning this, revolvers were shot in the left hand during those days. This was because you needed your right hand to hold the reins of the horse.
* Occurs twice in the Franchise/MarvelCinematicUniverse, when Thor is fighting Loki. Thor is initially holding back, not wanting to hurt his little brother, but then Loki pushes him too far. Both times Thor stops holding back, and promptly defeats Loki.
** In ''Film/{{Thor}}'', Loki actually does this on purpose wanting Thor to fight at full force. He makes a comment about "paying [[LoveInterest Jane]] a visit" to enrage Thor. Which didn't work out for him.
** In ''Film/{{The Avengers|2012}}'' Thor is desperately trying a GetAHoldOfYourselfMan to Loki. He seems to consider it, [[spoiler:and then stabs Thor sneering at the "sentiment". Thor promptly grabs Loki, lifts him into the air, before slamming him onto the ground.]] Director Joss Whedon even described this point as Thor "finally having enough of Loki's shit."
** Thor pretty much {{Lampshades}} it in ''Film/ThorTheDarkWorld'', telling Loki that all the previous times they'd fought, Thor held the hope that the brother he loved remained somewhere, and that hope no longer exists to protect Loki from Thor's wrath.
** This is discussed in ''Film/SpiderManHomecoming''. Spidey is trying to convince Iron Man he's ready to join the Avengers and points out how well [[Film/CaptainAmericaCivilWar he fought against Captain America in Berlin]] as an example. Iron Man points out that Cap was holding back because he didn't want to harm him. If Cap went all out, Spidey would've been beaten badly.
** ''Civil War'' also features War Machine, who mostly sticks to melee and repulsors (which have variable impact). Right up until [[spoiler:Ant-Man goes huge and tries to swing a bus at him, at which point War Machine unloads ''all his other guns''. The bus basically disintegrates.]]
* A sort of meta example in ''Film/JurassicWorld''; after a panicked ''[[PteroSoarer Pteranodon]]'' grabs Creator/{{Katie McGrath}}'s character and flies off with her, she manages to escape her captor by falling into the lagoon at the center of the park. The film seems to take a brief [[HopeSpot sigh of relief]] for her, leaving the audience to assume that all she has to worry about now is the ''[[SeaMonster Mosasaurus]]''...and then three ''Pteranodons'' promptly torpedo gannet-style into the water after her, showing that they're just as competent at swimming as they are at flying (which is believed to have been TruthInTelevision).
* There is an old live action kung fu movie which uses this Trope. One villain, who has chicken in his fake mustache and calls the hero a cur, initially wields a gigantic Cloud-esque sword. Eventually, this weapon tires him, and he pulls the hilt of the weapon out of the blade, revealing a tiny blade attached to the removed hilt which he uses much more effectively.
* Inverted in ''Film/BlazingSaddles'': When Jim, The Waco Kid, is explaining his backstory (and downfall) to Bart:
-->'''Jim:''' See this hand? ''[holds out his right hand]''\\
'''Bart:''' Steady as a rock!\\
'''Jim:''' Yeah, but I shoot with this hand. ''[holds out his left hand, which shakes violently]''
* ''Film/TheyMadeMeACriminal'': Johnny the boxer is TheSouthpaw, and also a fugitive from the police, having been unjustly accused of murder. He gets a bout out in the boonies of Arizona, but fights right-handed so that no one will recognize him. He thus winds up taking a beating, until the cop who's tracked him down says not to bother as the cop already knows who he is. Johnny then starts fighting lefty and gives a much better account of himself.
* There is an homage/send-up of a similar scene from Creator/DannyKaye's ''Film/TheCourtJester'', where Kaye goes from stumblebum to master swordsman with the sound of a finger-snap while fighting Basil Rathbone.

* The trope name and the page quote come from ''Literature/ThePrincessBride''. Inigo Montoya is so good that he fights with his left hand just to keep things somewhat challenging, but when faced with the Man in Black, he realizes he's being outmatched, and switches the sword back to his right hand to gain the upper hand again. [[spoiler:Too bad the Man in Black was ''also'' fighting with his off-hand, presumably for the same reason.]] In the film, [[FreezeFrameBonus if you look closely]], you'll notice when the Man in Black first starts to draw his sword, [[spoiler:he is drawing it with his right hand until he notices that Inigo plans to fight with his left hand.]]
* In ''This Book is Not Good for You'' from the Secret Series bynP. Bosch, Señor Hugo goes along as a blind man but eventually reveals he still has one good eye.
* Appears a couple of times in Franchise/StarWarsLegends novels.
** ''[[Literature/XWingSeries Starfighters of Adumar]]'' has a scene where Wes Janson faces a foe in a sword fight, and uses his weapon in his left hand. This is actually a feint, as he immediately uses his free right hand to disarm his overconfident opponent. After that the fight becomes a brutal display of how his extremely skilled opponent never bothered to train for situations where he would not actually have a weapon.
** In Drew Karpyshyn's ''Literature/DarthBane: Path of Destruction'', Bane eventually has to fight Kas'im, the Blademaster from the Sith Lord academy where he had trained, who uses a two-bladed lightsaber. Though Kas'im is the foremost MasterSwordsman of the Sith, Bane is stronger in the Force and, after training with Kas'im privately for countless hours, already knows all his moves. The pupil is at first beating the master... until [[spoiler: Kas'im detaches his saber-staff into two separate sabers, revealing that the ''real'' reason he has been telling his students DualWielding is useless is so that no-one else would learn it, or how to defend against it, which Bane indeed now can't.]]
** In [[Literature/RevengeOfTheSith the novelization of]] ''Film/RevengeOfTheSith'', Count Dooku is disappointed at how easily he's defeating Obi-Wan and Anakin, until it is revealed that they have been disguising how good they've gotten at their favored fighting styles by using lightsaber forms they are less familiar with, and have [[JustToyingWithThem just been screwing around]] to throw him off. Once they start fighting for real, Dooku realizes how badly outmatched he is and begins to panic.
* Iorek Byrnison pulls one of these in his fight against Iofur Raknison during ''[[Literature/HisDarkMaterials The Golden Compass]]'' by pretending his left arm is too badly hurt to be used in the fight. Bonus points considering that in Real Life most polar bears have a stronger left fore paw.
* Daniel in ''Literature/TheDangerousDaysOfDanielX'' by Creator/JamesPatterson. It's not that he discovers a new power, but more like he discovers a new combination of attacks to defeat the villain.
* ''Cats Have No Lord'' by Will Shetterly deliberately echoes the ''Film/ThePrincessBride'' trope, up until the "I'm not left-handed either," which is not true, but a ruse to distract the opponent so that sand can be thrown in his eyes.
* Happens literally in the second installment of the Toldi Trilogy, written by János Arany. The titular hero participates in a tournament for the sake of fighting, but is not interested in claiming the prize (marrying the daughter of the host), so he agrees with a left-handed knight (who is in love with the girl in question) to impersonate him. During the final duel, he almost gives himself away when he switches hands, because he can't handle his opponent while holding the sword in his left hand. The trope is inverted when he's eventually challenged by the same left handed knight he impersonated, over a matter of honor and Toldi is unable to get an edge over him, because he's not used to fighting left handed opponents. He eventually defeats his rival using his left hand.
* Creator/BrianDaley's ''The Starfollowers of Coramonde'' has a character named Brodur who uses his right hand in fencing while setting up a hustle bet, and insults his opponent by saying, more or less, "I could beat you, even left-handed." Brodur ''is'' left-handed, and once the bet is for ''big'' money, he shows it.
* In the fifth ''Literature/SkulduggeryPleasant'' book (''Mortal Coil''), Skulduggery and China corner an expert swordsman by the name of Burgundy Dalrymple and ask him to surrender. He appears to be thoroughly beaten and remarks on how the heroes seem to have bested him when he suddenly swaps his sword to his left hand and proclaims, "I am not right handed!" The exchange leading up to that moment is an almost word for word parody of the Princess Bride.
* The Royal Manticoran Navy of the ''Literature/HonorHarrington'' series required their newly-built pod-laying Superdreadnoughts to do this in the run up to their all-out offensive, in order to conceal the existence of the ship type and their revolutionary abilities from the enemy. The result was SD(P)'s performing at a fraction of their capability...and still annihilating enemy squadrons all by themselves.
** ''War Of Honor'' [[DeconstructedTrope shows what happens]] when you reveal this too early: The Manticorans are forced back onto their heels by the Havenites unexpectedly pulling this, thanks to Admiral Shannon Foraker being a very busy girl during the Cease Fire. They reveal some devastatingly powerful new superweapons, but they are not ready to deploy them to the entire fleet yet. Realizing this, the Havenites send what is, at that point, the largest battle fleet in history in an all-or-nothing bid to crush the Manticoran homeworlds' defenses and force a surrender. [[spoiler: They fail, but not before over a million people on both side die in the battle.]]
** This was also policy later when they found themselves in skirmishes against the Solarian League, to run the starship impeller drives at lower acceleration and fire from ranges that would only need two drives of their Multi-Drive Missiles rather than the range offered by the full three. This was, in significant part, to prevent the much larger Solarian League from realizing how badly outmatched they were in case the Manticorans couldn't prevent an all out war.
** Unfortunately for the Manticorans, this was ''also'' the case for the [[spoiler: Mesan Alignment Navy]], who managed to conceal their entire ''existence'' behind the front of the comically inept and corrupt Mesan Navy. Their first move against the Manties? [[spoiler: [[SittingDuck Oyster]] [[CurbStompBattle Bay]]]].
* Bohun pulls this literally in first instalement of Literature/SienkiewiczTrilogy, by throwing his saber from one hand to another (movie version makes it look ''very'' epic). It's useless against Volodyjowski, who [[CurbStompBattle takes him down right after that]].
** Although this was one-off surprise attack (described as a trick only best duelists could pull off), good against average opponent but not so useful against the professional knowing all tricks of the trade.
* Jaime Lannister averts this trope in ''Literature/ASongOfIceAndFire'' in the most heartbreaking way after [[spoiler: the Bloody Mummers cut off his right hand]]. He tells people jokingly that he only let them do it because he wanted to make swordfighting more interesting. In reality, however, he's not remotely competent with his left hand - he can't even hit a bear with a thrown bone.
* At the beginning of ''Knife of Dreams'' in ''Literature/TheWheelOfTime'' series, Galad deliberately holds back for most of his fight with Eamon Valda, attacking and parrying a bit more slowly than he could have. Then, at the end of the fight, he goes all out.
* ''Literature/LegacyOfTheDragokin'': Ravage has a SuperMode that makes him bigger and stronger and tougher; he uses it when Finn gains the upper hand in their fight.
* Alanna does this in the second book of ''Literature/SongOfTheLioness''. She's chosen to duel for Tortall's honor when a knight from Tusaine's delegation insults them; when he wound her in the right arm and presses for the kill, she switches her sword to her left hand and defeats him. This is a ChekhovsSkill from the first book, when she was shown learning to fight left-handed after breaking her right.
* In Joel Rosenberg's ''Not Exactly The Three Musketeers'', the main characters meet an elderly wizard who challenges them to an arm wrestling match to prove how powerful the illusions he's selling are. He seems to transform into a young, muscular man and beats them easily; it takes them a while to see through his con: he actually ''is'' young and brawny, but using an illusion to make himself look old.
* Literature/JohnCarter, the "Greatest Swordsman of Two Worlds", deliberately sandbags a couple of times over the course of the series, usually because has a secret plan and he's stalling for time while it comes to fruition. He fights just barely well enough to keep from getting killed and takes the offensive just enough to keep his opponent from getting suspicious until he finally sees whatever it is he's been waiting for, at which point the fight is generally over within seconds.

[[folder:Live-Action TV]]
* The very first episode of ''Franchise/PowerRangers'' had Zordon tell them that they should never use their [[HumongousMecha Zords]], except after attempting all lesser attacks, as a code of honor. This is also a {{handwave}} of the ForgottenSuperweapon phenomenon.
* Played with in an episode of ''Series/TheSixMillionDollarMan''. Steve Austin has to go undercover on an American Indian reservation, and there's a section of the reservation he needs to get to, but the problem is that only members of the tribe are allowed to go there. If he can pass several physical tests, he can become an honorary member of the tribe. His bionically-augmented body lets him pass the tests easily, but the last test is to arm-wrestle the strongest men in the tribe. While his bionic right arm lets him beat all the challengers, the medicine man for the tribe won't accept his victory unless Steve beats him as well. The medicine man then insists his right hand is "for medicine only" and says he will only arm-wrestle Steve left-handed. It quickly becomes apparent that the medicine man is one ''hell'' of a lot stronger than he looks. Steve narrowly wins, but it's very close and it's clear that it took all the strength Steve had in order to win, and his face shows it.
* The ''Series/StarTrekTheNextGeneration'' episode "Q-Pid" plays with the Myth/RobinHood legend, featuring this exchange:
-->'''Sir Guy of Gisbourne:''' I am the best swordsman in Nottingham.\\
'''Picard:''' ''[as Robin]'' I am not ''from'' Nottingham!
* In ''Series/{{Entourage}}'', Ari attempts to trick a studio executive into betting Vince into a movie during a golf game - he purposely loses the first nine holes before making the bet, and then his game miraculously improves. The exec accuses Ari of trying to trick him - then reveals that he plays much better left-handed, and goes on to defeat Ari.
* Series/{{Angel}} does this on a regular basis, usually revealing that he's a vampire about halfway through the fight. Vampires, for example, do not breathe, which Angel noted way back in ''Series/{{Buffy|the Vampire Slayer}}'' when a character needed mouth-to-mouth.
-->"Right now I'm crushing your windpipe."\\
"Guess what I'm doing now? Not using my windpipe."
* Jack Deveraux does this while fencing Lawrence Alamain in ''Series/DaysOfOurLives''. Rather than reveal he's not right-handed during the fight, he waits until he's already defeated Alamain, to twist the knife in even more.
* In the ''Series/DoctorWho'' episode "The Christmas Invasion", the bad guy has the Doctor at a disadvantage in their challenge sword duel, and slices off his right hand. The Doctor, however, ''grows a new one instantly'' due to previously-unknown AppliedPhlebotinum, dubs it a 'fightin' hand', and proceeds to soundly defeat the bad guy.
* In ''Series/BandOfBrothers'' this trope appears in such perfect form it almost looks like it was the [[TropeNamers Trope Namer]]. In the 4th episode ("Replacements"), Buck Compton plays darts against one of the new guys -- Heffron -- and loses saying, "It's a good thing we weren't gambling." Heffron suggests they bet on the next game and Buck "reluctantly" agrees. Before Buck takes his shot, he switches to his right hand and wins easily. Heffron has just enough time to realize he's been conned.
-->'''George Luz:''' Lieutenant, are you going to shoot lefty all night?\\
'''Joe Toye:''' Hey, c'mon.\\
'''George Luz:''' I'm just curious cause he's right-handed.\\
'''[='Buck'=] Compton:''' ''[switches hands]'' George, what would I do without George Luz?
* In an episode of the ''Series/MadTV'' recurring skit "Average Asian", a man challenges said Asian to a game of ping pong. After losing, the Asian says "Let me put the paddle in my OTHER hand" needless to say, "He's an expert Asian! When it comes to ping pong!"
* ''Series/XenaWarriorPrincess'': Joxer pulls this, in an almost word-for-word send-up of the famous scene from ''Film/ThePrincessBride'', while fighting under a spell cast by Aphrodite that turns him from TheScrappy to TheLancer at the ring of a bell.
* ''Franchise/{{Zorro}}'':
** ''Series/TheNewAdventuresOfZorro''. "I am the greatest swordsman in Baja California!" "Unfortunately, you are in Alta California."
** In the 1957 Disney ''Series/{{Zorro}}'' TV series, Don Diego de la Vega is a master swordsman, with many awards for his swordplay in Spain. When he decides to become a sword-fighting vigilante, one of the first things he does is to dispose of his awards so as to better pass himself off as a clumsy IdleRich to his new neighbors in California. One episode's plot naturally revolves around Don Diego being challenged to a duel, and having to somehow win while ''still'' fighting left-handed (figuratively speaking) so as to avoid blowing his cover.
* ''Series/EverybodyLovesRaymond'': After Ray loses a ping-pong match with his father, his father reminds him that "it's a good thing he wasn't using his good hand" and switches his paddle to the other hand.
* ''Series/BuffyTheVampireSlayer'':
** "The Freshman": A vampire has busted Buffy's left arm up, and she's spent most of the episode conspicuously not using it and fighting one-handed. Then...
-->'''Buffy:''' When you look back at this, in the three seconds it'll take you to turn to dust, I think you'll find the mistake was [[BerserkButton touching my stuff]].\\
'''Sunday:''' What about breaking your arm? How'd that feel?\\
'''Buffy:''' [[UseYourHead Let me answer that with a head butt.]] And for the record... The arm is hurt, not broken. ''[punches Sunday halfway across the room with her left hand]''
** Later at the end of Season 4, Buffy manages to break the skewer (which had been Adam's primary weapon). Her triumph is short lived. Bonus points for the skewer coming out of Adam's left arm.
-->'''Buffy:''' Broke your arm.\\
'''Adam:''' Got another. ''[his right arm turns into a [[GatlingGood gatling gun]]; cue an OhCrap look from Buffy]'' I've been upgrading.
* Joss Whedon scores a hat trick here; in the pilot of ''Series/{{Firefly}}'', the titular vessel ''Serenity'' is fleeing a Reavers vessel hot on her heels and bearing down upon her -- turns out that her thrusters ''rotate all the way round'', allowing her to pull a Crazy Ivan and escape.
-->'''Wash:''' Here's something you can't do.
* In ''Series/SpinCity'', it is a rule that when you play racquetball against the mayor, you lose (intentionally). But then Charley is stressed out because of his work and the mayor taunts him one too many times. Charley switches his racket from his left to his right and gruesomely beats the mayor.
-->'''Mayor:''' I thought you were left-handed?\\
'''Charley:''' [[LampshadeHanging Not anymore.]]
* It would seem Joss Whedon is very fond of this trope indeed: it comes up again in Season Two of ''Series/AgentsOfSHIELD'', when brain-damaged GadgeteerGenius Fitz is sent on his first post-recovery mission and is told he will have to reassemble and install a transceiver in under six minutes, despite only having one fully functioning hand. He's shown practicing the procedure one-handed and growing frustrated at his inability to work quickly enough, though he's eventually able to trim it down from eleven and a half minutes to just over seven. When Coulson points out this still won't cut it, Fitz tells him that it only takes him that long ''using only his bad hand''... with both, he'll be just fine.
* ''Series/{{Leverage}}'':
** In the season two episode "The Tap Out Job," Sophie ''panics'' when she realizes that the mark, not trusting Eliot's promise to [[ThrowingTheFight throw an MMA bout]], has [[TamperingWithFoodAndDrink drugged his water]]... and thus taken away his ability to [[TheFettered hold himself back]]. [[spoiler:It turns out it's all part of the con and Eliot didn't actually drink the drugged water, but other dialogue during the episode suggests that Sophie's description is not inaccurate.]]
--->'''Sophie:''' [Eliot] fights to survive, that's his training. It takes all his control ''not'' to kill somebody! You've just made him more dangerous! ''You've taken the safety off the gun!''
** Eliot does it again in "The Big Bang Job". After three seasons of insisting he doesn't like guns and handling them only to dismantle and toss them away, he finally picks up a pair of handguns in order to face off with a good dozen mooks working for the season's BigBad. The absolute carnage that follows hits just about every gunplay trope in the book.
--->'''[[MookLieutenant Chapman]]:''' You said you didn't like guns.\\
'''Eliot:''' I don't. ''[unloads four rounds rapid-fire into Chapman's chest]'' Never said I couldn't use them.
* In one episode of ''Series/MissionImpossible'', Willy has to compete in a judo competition, and it's all he can do to keep from losing long enough for the rest of the team to do what they need to do while he is distracting the audience with the match (despite Willy's considerable strength, he has never trained in judo before the start of the mission). At the end of the episode, he ends up fighting the villain's judo champion again, and since it's not a formal match, Willy switches to jujitsu, a martial art he ''has'' trained in, and mops the floor with him.
* In ''Series/TheFlash2014'', after Cisco learns to reliably produce Vibe blasts from his hands, he doesn't use them much. When he needs to take down [[spoiler:Killer Frost]], he is reluctant and holds back for fear of hurting her. When Julian finally convinces him not to hold back, he rather easily wins a BeamOWar with her and then blasts her into unconsciousness. It's no wonder the Killer Frost and Deathstorm of Earth 2 were afraid of his double Reverb, who told Vibe that he had no idea how powerful he could become.
* ''Series/BabylonFive'':
** Done to tragic effect in the backstory: during the early phases of the Earth-Minbari War the Minbari inflicted a small series of [[CurbStompBattle Curb-Stomp Battles]] against [=EarthForce=] until Sheridan managed to nuke the Minbari flagship during a raid in the Sol System, prompting the Minbari to pull back for a while-and then come out more unstoppable than ever, as the raid in the Sol System was a scouting manouver to prepare a decapitation strike because they didn't want to ''fully mobilize their standing force''. After that loss, however, the Minbari got serious and, even without mobilizing their reserves, they methodically occupied the whole Earth Alliance and destroyed [=EarthForce=] as they slowly but inexorably came for Earth to start the complete destruction of Mankind.
** Done by ''[=EarthForce=]'' during the conflict against the Ch'lonas, the Koulani and Drazi raiders. It was not by choice, as the conflict happened at the same time as the Earth-Minbari War and what they used to hold the line was what they could spare from [[HopelessWar the desperate attempts to slow the Minbari down while they tried to evacuate the Sol System and the Inner Colonies]]. Once the Minbari suddenly surrendered, however, the remnants of [=EarthForce=], augmented by the ships that had been put into production in the previous months and didn't need to be sent against the Minbari (whose numbers included the augmented variants of the ''Hyperion'' that had been sent against the Minbari and the brand-new ''Omega''-class destroyers), went after the Ch'lonas, the Koulani and Drazi raiders, and showed them the difference between what Earth could spare to fight jackals while also dealing with a HopelessWar and a battle-hardened force equipped with state-of-the-art weapons.
* In the seventh season of ''Series/GameOfThrones'', this trope comes up on a strategic scale. Daenery Targaryen invades Westeros with both a vast army and three dragons, which are for all intents and purposes [[GameChanger Game-Changing]] [[FantasticNuke Fantastic Nukes]]. Right off the bat, she's in the position to take the capital by force, but doesn't - she has no intention of becoming "queen of the ashes", so she settles for more conventional warfare using her Unsullied legion and Westerosi allies. This allows enemy commanders Jaime Lannister and Euron Greyjoy to outmaneuver her, dealing her several stinging defeats. At that point, she decides she's had enough playing around and attacks the rear end of the Lannister army with both the Dothraki hordes and one of her three dragons, utterly [[CurbStompBattle curb-stomping]] them and making it abundantly clear what will happen if she decides to stop holding back.

[[folder:Video Games]]
* Can be invoked when battling in a ''Franchise/{{Pokemon}}'' game. Whenever some boss, such as the champion, evil team leader, etc. sends out their last pokemon as a last resort, as a general rule, it's usually the most powerful. Taken even further in generation six and onward, as mega evolution and primal reversion are introduced as game mechanics. A boss NPC can have their last pokemon mega eveolve, because why not? And an ancient pokemon undergoing [[ThisWasHisTrueForm primal]] [[OhCrap reversion]] is actually returning it to the overpowered form it once was a long time ago.
* In many shooting videogames, players are often limited to usually using a pistol or shotgun, due to lack of ammo for more powerful weapons. This often leads to them saving the {{BFG}} for DemonicSpiders or ThatOneBoss.
** Which is usually built into the game's expected strategy. A good example is TimeCrisis3. The first stage gives you a grenade launcher with two rounds near the end. Experienced players will save it where the final boss, a giant tank turret, can be eliminated with just those two rounds. Less savvy players will use them in the trenches to clear out corners filled with enemies and have only the pistol left for the boss.
* Same with {{Role Playing Game}}s, where players will just keep on using regular attacks on the regular mooks they encounter to save up items and MP, only to open the whole can of whoop-ass on stronger enemies.
* Played with in ''VideoGame/SuperRobotWars''. Sanger Zonvolt is best known for piloting a mech whose only weapon is [[{{BFS}} the Type-3 Zankantou]] and which uses a custom operating system that turns it into a MotionCaptureMecha. In OG Gaiden, a villain tries to take advantage of this by disabling the Zankantou, only for Sanger to switch back to the default OS and kick his ass with the onboard weapon systems. The catch is that these weapons had never made any kind of in-game appearance before and had only been referred to via concept art in the artbooks for SRW Alpha 2 (where Daizengar made its first appearance). So it's less "I Am Not Left Handed" and more "I ''AM'' Left Handed, But I Can Kick Your Ass With My Right Hand Too".
* Nero does a form of this in his fight with Dante in ''Franchise/DevilMayCry 4'': he's been keeping his [[EvilHand Devil Bringer]] hidden under the pretense that his arm is broken and he must carry it in a sling. He fights Dante for the majority of their first contact with his right arm hidden in the sling, and just when Dante has the upper hand and is about to run Nero through, he suddenly throws the sling off and blocks Dante's sword with his cursed arm, stopping Dante in his tracks.
** Dante himself pulls this in the same game. The fight mentioned above works as the game's tutorial because Dante's not [[JustToyingWithThem putting a whole lot of effort into it.]][[note]]He spends the first half of the scuffle causally evading or deflecting Nero's (read: the player's) attacks, and doesn't even bother with his usual TrashTalk.[[/note]] The next time he and Nero clash, [[TheGlovesComeOff the kid gloves are gone]] and it's considered by many to be the most [[ThatOneBoss difficult fight in the game.]]
** Vergil also does this in ''3''. In the first fight against him he stays in human form all the while. By the second fight he pulls out the [[SuperMode Devil Trigger]] after you damage him enough. In the third and final fight, he gets to use an even more powerful SuperMode on top of the previous one with deadly SecretAIMoves.
*** It should be noted about the Devil Trigger, that before 3 it is played up like Dante has never been able to access it, so after Vergil kicks his ass in a cutscene after the bossfight that it awakens Dante's own abilities. Sort of giving Dante his own "I Am Not Left Handed". In fact in all the games save for 2 and 4 Devil Trigger isn't attained until a certain point so it's always been a hidden SuperMode technically.
*** In the first game, the default sword Force Edge is it's own "I Am Not Left Handed", in the fact it doesn't have a Devil Trigger form for Dante, and not until the right moment releases it's true power to become the sword Sparda, which let's Dante Devil Trigger into his father's Demon Form.
* Some time after [[spoiler:his death]] in [[VideoGame/FireEmblemTellius Fire Emblem 9/10]], Greil is revealed to have [[spoiler:crippled his sword arm because Lehran's medallion caused him to go AxeCrazy and kill his wife.]] When [[spoiler:the Black Knight finds out he didn't fight the true Greil because of this, he holds back in his final fight in [=PoR=] so that Ike will become stronger and show him what Greil was truly capable of.]]
** And the person that reveals this to the player also counts.[[spoiler: Volke is actually an assassin hired by Greil to kill him just in case he goes berserk again. After the revelation Volke gets his promotion from thief to assassin. And then makes the same deal with Ike.]]
* ''VideoGame/CommandAndConquerTiberianDawn'': The Commando unit created the "That was left-handed!" phrase, which is well known and referenced throughout the series.
** Subverted by Boris in ''VideoGame/CommandAndConquerRedAlert2''. He seems to legitimately be left-handed, given from how he holds his rifle. It also appears to be a left-handed variant (given where the ejection port is).
* In ''VideoGame/TalesofSymphonia'' Regal Bryant fights only using kicks, keeping his hands shackled. [[spoiler: Late in the game, you find out firsthand that when he fought using his hands, he was as or more powerful then, than the team is currently, and that was without the Exspheres that allow them to be powerful.]]
* Joshua of ''VideoGame/TheWorldEndsWithYou'' at first appears to be a PrettyBoy who fights with a psychic cell phone. He can't jump, and his ground combos only deal damage after the last button is pressed (Shiki and Beat can deal damage with every press). However, when Joshua and Neku are confronted by a Taboo Noise, and all hope seems lost, Joshua suddenly reveals [[PowerFloats he can levitate]] and proceeds to vaporize the Noise with a [[FanNickname Jesus Beam]]. Afterwards, the reaper, Koki Kariya, confronts Joshua and notes that such power can only come from someone [[spoiler:who is still alive while playing the game]], and he tells Joshua that he will let it pass as long as Joshua doesn't pull the same stunt again, because the reapers themselves were having trouble with the Taboo Noise. [[spoiler:He later goes all the way up to AGodAmI when he reveals that he is Shibuya's Composer, TheManBehindTheMan.]]
* ''VideoGame/LufiaIIRiseOfTheSinistrals'': After the first boss fight with Gades, if you manage to defeat him, he toasts your party anyway in a cutscene.
* ''VideoGame/ChronoTrigger'': Slash, one of Magus' [[QuirkyMinibossSquad generals]], is as famed as a legendary swordsman as his comrades are for their control over magic. When confronted, he puts up a respectable fight, but something just seems to be missing... until halfway through, when he acknowledges the team's prowess and takes his sword off the wall. Uh-oh.
-->'''Slash:''' You're more powerful than I thought! I better use all of my strength as well. ''[pulls sword off of wall]'' And you, without Cyrus... ''[unsheathes sword in slashing motion]'' '''You've no hope!'''
** Some gamers still have a soft spot for his old battle cry. "Yes, indeed!" heralded ''pain''.
* In ''VideoGame/GuildWars'', one of the NPC henchmen, Lukas, will occasionally shout "I am not right handed!" as one of his combat dialog lines. (he wields his sword in his right hand, of course)
* ''VideoGame/AceCombatXSkiesOfDeception'' has the mission Time Limit, where an unstable neutralising agent forces Gryphus One to fly slowly and with reduced maneuvering. Two Leasath pilots proceed to trash talk about how he's not what [[ShroudedInMyth the rumours make him out to be]] and stalk him in this near-defenceless state. When Gryphus One finally gets to discard the neutralising agent and dogfight properly, the two are taken aback by his real prowess and don't last long.
* Akuma from ''Franchise/StreetFighter'' does this deliberately. The form everybody sees him in is Akuma using only part of his power. [[SuperpoweredEvilSide Shin Akuma]], however, is when Akuma stops holding back and goes full-force at whomever he's fighting. Considering every version of this form that a player can fight doubles as an SNKBoss, it's lucky he doesn't do it more often.
** [[OldMaster Oro]] from the ''VideoGame/StreetFighterIII'' series keeps his arm binded in his gi sleeve so he doesn't accidentally kill his opponents. He gets to use both his arms in powered-up versions of his supers in ''Third Strike''.
** Applies to Cody as well, who intentionally wears his handcuffs for this very reason.
* Shadow's story in ''VideoGame/SonicTheHedgehog2006'' seems to be setting up a BolivianArmyEnding, with Team Shadow surrounded by an evil army of magic clones. Then Shadow removes the PowerLimiter rings on his gloves, and proceeds to wipe the floor with them.
** Which is an idea that was first implemented in ''Anime/SonicX'' where he removes the ring to better use the Chaos Emerald's powers, though weakening him in the process. This is noted mainly during the final battle of the ''VideoGame/SonicAdventure2'' StoryArc of the show when he goes {{Super|Mode}} with Sonic and stops the ARK from falling on Earth by removing the rings again to give him enough juice.
* Sonic himself pulls this in ''VideoGame/SonicBattle'' as well as a LetsGetDangerous, when he has to fight [[spoiler:[[UnwittingPawn Em]][[WithGreatPowerComesGreatInsanity erl]]]]. Surprisingly, this is one of the few (if not the only) instances of Sonic not playing around with his opponent or in general. He goes from an adrenaline-pumped and cocky KidHero to (disturbingly) ''a deathly serious and utterly PragmaticHero.'' Then again, when you have '' '''30 seconds on the clock''' '' (the previous 30 seconds spent trying to negate the Chaos Emeralds with the Master Emerald and ''FAILING'') before the FinalBoss (who happens to be a ''PhysicalGod'') blows your home planet to nothing with '' '''A STAR SYSTEM BUSTER''' '' and the only way to do stop them is to ''KILL'' them [[spoiler:([[KillTheOnesYouLove and it's someone you really care about]])]] why would he play around? Sonic just proved why he is the fastest hedgehog alive and that he's got some '''serious''' brass ones. He's been holding back a lot more than what we believed he did.
* Ragna the Bloodedge from ''VideoGame/BlazBlue'' holds great power in the Azure Grimoire [[spoiler: copy/fake]] that makes up his right arm, but refuses to use it for much of the game. When he does, stuff starts hitting the fan ''very'' quickly.
** BigBad Hazama/Terumi does this too [[spoiler: as he created the Azure Grimoire.]]
* ''VideoGame/ZenoClash''[='s=] second Hunter battle begins with the titular boss keeping one hand behind his back as he fights you. (This is in addition to the fact that he's ''[[HandicappedBadass blind]]''.) Whittle his health down enough and he brings both arms into play - ''[[HopelessBossFight and beats the living hell out of you.]]''
* In a cutscene in the ''VideoGame/FinalFantasyVII'' prequel ''VideoGame/CrisisCore'', Sephiroth and his then-friends Genesis and Angeal are having a 'play fight' on the Junon Cannon. However, when Genesis gets carried away and goes overboard, Sephiroth reveals just how much he was holding back earlier. Cue CurbStompBattle, complete with kickass version of [[CrowningMusicOfAwesome One-Winged Angel.]] Even better, WordOfGod says he ''still'' hasn't been seen at his full power. Also played upon, as he is using his right hand in most scenes, but he is actually LEFT HANDED.
* ''VideoGame/WorldOfWarcraft'':
** The Lich King manages to pull this in the final fight in ''Wrath'', when he stops messing around and slays your entire party with one attack.
** Most raid bosses have a berserk timer; when they hit it, they gain an additional attack that will let them wipe the floor with the raid. Makes you wonder [[WhyDontYouJustShootHim why they didn't just lead off with that attack.]]
* ''VideoGame/ResidentEvil4'' often requires this to be able to survive the tougher enemies. One can buy a rocket launcher and make quick work of what was originally to be a boss that could easily kill you. The fully upgraded Broken Butterfly will also get the job done.
** El Gigantes are most notable examples. Instead of having to shoot them multiple times, then attack their parasites, you just need to shoot them once with a rocket.
** Shoot Salazar's "Right Hand" with the upgraded Broken Butterfly or a rocket launcher after freezing it the first time and it will shatter.
* The ''VideoGame/{{Fallout}}'' games allow you to specialise in many different weapon types. You can be really good at using [[KineticWeaponsAreJustBetter ordinary ballistic firearms]] but choose to use [[RayGun energy weapons]] even if your skill with them is weaker but you like the pewpew effects. But when it comes down to fighting a particularly tough enemy, you can always put the laser rifle away and switch to a high-powered [[InfinityMinusOneSword Anti-Materiel rifle]] with explosive ammunition and turn a [[TheJuggernaut deathclaw]] into [[LudicrousGibs bloody chunks]].
** Unfortunately your {{Non Player Companion}}s in ''VideoGame/{{Fallout 3}}'' and ''VideoGame/FalloutNewVegas'' are never left handed and will nearly always use the biggest weapon you have given them. Players using their companions as pack mules must take care to never give one both the weapon and the ammunition to carry at the same time, lest they find their sidekick firing your carefully hoarded and expensive missiles against molerats.
** ''Fallout New Vegas'' when playing with the GRA DLC installed active encourages the player to be left handed. Part of this DLC adds a series of Challenges that often require the player to kill powerful enemies with horribly unsuitable weaponry, i.e. killing 5 adult Deathclaws using the absolute weakest weapons in the game, or killing 10 of the extremely quick and erratic Cazadores using explosives that have a long fuse timer before detonating. While the savvy player will realize that only the killing blow needs to be delivered with the required weapon, and hence soften up the target with something more sensible first, most of these Challenges are still excellent ways to discover when the player last made an autosave.
* In ''[[VideoGame/DarkForcesSaga Jedi Academy]]'' it's possible to switch lightsaber styles (there are five in the game; depending on your choice of lightsaber you can get at most three of them), and Kyle even recommends you do it for this trope's sake. The extreme effectiveness of doing this was carried over from the previous game, ''Jedi Outcast''. The Strong style is actually only useful for this in lightsaber fights, ending a battle or knocking the enemy's lightsaber out of their hands (or both).
* In ''Videogame/AsurasWrath'', half-way through the fight with Augus, he relishes the fact that Asura is putting up a decent challenge and takes out his sword Wailing Dark, proclaiming that not even the finest wine or the fairest maiden excites him as much as using his blade. The game then cuts to Yasha and Deus, who senses this and notes that Augus has only ever used his sword once before, and that was with [[AuthorityEqualsAsskicking Deus]] himself.
* Wazy from ''VideoGame/ZeroNoKiseki'', leader of "Testament" gang, is constantly at odds with leader of a rival gang "Saber Viper", Wald, to determine which of the two gangs hold authority in Crosbell's downtown. In Ao prologue when Wazy joins SSS, Wald challenges Wazy for another match only to be [[CurbStompBattle easily defeated]], showing that he has been holding back in their previous duels. Near the end of the game, it's revealed that the reason Wazy was that strong is because he's [[spoiler: one of Dominion, twelve strongest fighters in Septian Church's [[ChurchMilitant Gralsritter]] with nickname "Blue Testament".]]
* In the ''Franchise/ShinMegamiTensei'' franchise, Stephen is always shown in a wheelchair, [[MrExposition provides necessary exposition]], developed essential tools for combating demons such as the Demon Summoning Program, and can heal the player's party. Beyond that, he doesn't do much. In ''VideoGame/ShinMegamiTenseiIVApocalypse'', [[spoiler:not only does he reveal himself to be capable of offensive abilties in combat, but, as part of a SecretTestOfCharacter to Nanashi and the protagonists of the previous four mainline ''SMT'' games, he can also stand up just fine and become the hardest BonusBoss in the game at level 128, putting him at an even higher level than YHVH (100), the game's FinalBoss; in other words, Stephen is more powerful than ''God Himself''.]]

[[folder:Visual Novels]]
* Gilgamesh of ''VisualNovel/FateStayNight'' is easily capable of defeating any of the Servants simply by [[StormOfBlades raining an endless number of Noble Phantasms down on them]]. However, he does not subscribe to [[ThereIsNoKillLikeOverkill overkill theory]]; even though he uses overwhelming force in battle, he could easily use ''even more'', but chooses not to. Most notable is his refusal to bring out Ea, a sword capable of destroying ''worlds'', unless very impressed or in significant danger. Even then he never uses more than a small fraction of Ea's true power, since destroying the planet he's standing on would be a very ''stupid'' thing to do.
* In ''VisualNovel/SharinNoKuni'' [[spoiler: when Kenichi fights Houzuki, he finds out that Houzuki's leg is actually completely fine, and promptly loses the fight as a result.]]

[[folder:Web Comics]]
* ''The God of High School'': Jin Mo-Ri's power level is estimated at level six when he first enters the tournament. That is, until he actually uses his legs to attack, which more than doubles his power level to 13. Furthermore, the judges revealed to be holding back by not using their special abilities.
* ''Webcomic/DominicDeegan'' parodies it [[http://www.dominic-deegan.com/view.php?date=2005-09-28 as well]].
* In ''Webcomic/DragonMango'', the elf Eclair wears a heavy iron armor breastplate. Iron usually causes them massive pain; Eclair turns out to be wearing it purely for the weight and pain handicaps.
* In ''Webcomic/{{Juathuur}}'', Rowasu [[spoiler: considers his sword a ''handicap''. Notice that two opponents tried to disarm him.]] More specifically, [[spoiler:once the sword is no longer in his hand, ''the hand itself'' becomes a weapon]].
* ''Webcomic/BobAndGeorge'' [[http://www.bobandgeorge.com/archives/050227c (Non alternate) Mynd tries it.]]
* In ''Webcomic/GirlGenius'' pulled by [[MagnificentBastard Tarvek]]. First Violetta notices that he indeed ''[[http://www.girlgeniusonline.com/comic.php?date=20091125 was]]'' paying attention at the martial arts training. [[http://www.girlgeniusonline.com/comic.php?date=20110425 Later]]...
-->'''Tarvek:''' I'm sorry, Violetta -- as my days of needing the family to [[UnderestimatingBadassery underestimate me]] appears to be ''over'' -- I will no longer require your assistance in [[ButtMonkey this particular charade]].
* ''Webcomic/GunnerkriggCourt'' has a training example, in sparring between Parley (who is a ''good'' fencer) [[http://www.gunnerkrigg.com/archive_page.php?comicID=957 and S13]]. They dance a little, then Parley [[http://www.gunnerkrigg.com/archive_page.php?comicID=960 tells to stop holding back]]... to a robot going [[LeParkour extreme parkour]] merely [[http://www.gunnerkrigg.com/archive_page.php?comicID=636 to move around quickly]]. She also chose a much heavier blade. The next round [[KilledMidSentence ends before it starts]] and even when she's ready it doesn't take long. Of course, then Parley uses her talents fully, and [[http://www.gunnerkrigg.com/archive_page.php?comicID=962 she isn't constrained]] by the sword's inertia much when blinking around.
* In ''Webcomic/NoRestForTheWicked'', [[http://www.forthewicked.net/archive/04i-04.html Ricardo tells the princess it would have been over much more quickly if he had use of his right hand -- though, unusually, he doesn't show it, because his right arm's in a sling.]]
* Invoked in ''Webcomic/LeifAndThorn'' when a trainee beats Thorn in a sword fight, and an instructor uses this to deflate his ego. As Thorn says later, though, [[http://leifandthorn.com/comic/leaves-that-are-green-1121/ ever since his dominant arm was severely injured]], he actually fights ''better'' with the sword in his non-dominant hand.
* [[http://www.giantitp.com/comics/oots1068.html This female frost giant]] in ''Webcomic/TheOrderOfTheStick'' stops holding back once her male companion is dead.

[[folder:Web Original]]
* ''WebVideo/TheNewAdventuresOfCaptainS'': In the final showdown between Captain S and the Game Genie, Captain S seems to have the Genie's number before the Genie proclaimed "We're not [=*snort*=] left-handed." and proceeded to transform into his true form
* After failing to do any damage to Malachite in ''Webvideo/SuburbanKnights'' using their costumed weapons (which makes sense since they were mostly just props) everyone abandons their "characters" (Lupa stops acting princessy, Linkara starts using his magic gun, Angry Joe gets out his weapon arsenal etc.) It still doesn't work though since Malachite is a dark mage while everyone else are mostly un-powered nerds.
* ''WebVideo/AtopTheFourthWall'': On the subject of Linkara's magic gun [[spoiler:a.k.a. Margaret, she]] has been holding back [[spoiler:her]] full strength most of the time. There are a couple sneak peaks of it in the "Silent Hill: Dead/Alive" and "Silent Hill: The Grinning Man]]" reviews, but we don't really properly see the gun cut loose until Star Wars 3D #1.
* In ''Franchise/{{Noob}}'', Gaea is a notable hoarder of both money and precious items and a DirtyCoward when it comes to combat. However, if she's cornered into combat and has her mind set on winning, [[spoiler:she does NOT consider her most powerful items to be Too Awesome to Use]].
* In ''Literature/{{Worm}}'' the [[{{Kaijuu}} Endbringers]] are always holding back when fighting. Every time they're sufficiently injured or hindered they'll bring out a new ability to mix things up.

[[folder:Western Animation]]
* In ''WesternAnimation/{{Doug}}'', Doug is playing baseball but plays horrible until Patty notices he favors his left hand and realizes he's a lefty. Once Doug swings left-handed, he actually plays competently. This is ironically the opposite of the name of this article.
* ''WesternAnimation/AvatarTheLastAirbender'': Zuko does this when fighting an earthbender and realizing that holding back his firebending to conceal his identity is no longer an option. This backfires on him, when the very people he was protecting and risking his life for [[UngratefulBastard treat him like dirt afterwards and run him out of town]], albeit understandably, seeing as Zuko's father ''is'' leading the army that's been oppressing them and aside from his one stray good deed they've only ever been mistreated by the Fire Nation before.
* ''WesternAnimation/TheLegendOfKorra'':
** "[[Recap/TheLegendOfKorraS1E8WhenExtremesMeet When Extremes Meet]]": Tarrlok resorts to [[spoiler:bloodbending]] when he runs out of water.
** "[[Recap/TheLegendOfKorraS3E11TheUltimatum The Ultimatum]]": Ming-Hua [[spoiler:[[MultiArmedAndDangerous does her best impression of]] [[Franchise/SpiderMan Doc Ock]]]].
* ''WesternAnimation/{{Grojband}}'' quotes this trope almost word for word when Corey dukes it out with a pirate captain in "The Pirate Lounge For Me".
* ''WesternAnimation/JusticeLeague'':
** The moment when Flash surpasses any speed ever achieved by a human being in order to whup Brainiac-Luthor's ass in the ''Unlimited'' episode "Divided We Fall". The episode practically gave the character an immediate boost from the goofy, comic relief of the League to an absolute badass in ''a few seconds''. And to show how serious he was, we learn that going that deep into the Speed Force runs the risk ''of not coming back''.
** At various times it is made very clear that Franchise/TheFlash, much like Superman, can cause ''a lot'' of collateral damage if he isn't careful. As for the above example, it's implied that he was approaching the speed of light and you can see cars flipping and distant windows shattering just from how fast he is moving. He outright doesn't use his ability to phase through solid material, because it can cause explosions or instant destruction.
** Superman lets himself get beaten up a lot because of this; he will fight using all of his powers, and he's beaten many times, but either because somebody broke out the [[KryptoniteFactor kryptonite]] or because he's holding back early on and for some reason can't go back to being right-handed. Case in point: when he unknowingly fights Wonder Woman, he has to stop fighting, period, once he realizes it's her, and is badly beaten up because of that. However, he frequently talks about the reasons he does this. At one point, he says that every hit he takes is one less hit his teammates has to. This especially comes to proof when Superman fights Darkseid in the series finale. After getting beat down, Superman gives his famous WorldOfCardboardSpeech:
--->'''Superman:''' I feel like I live in a world made of ''cardboard''. Always taking constant care not to break something, to break someone. Never allowing myself to lose control even for a moment, or someone could ''die''. But you can take it, can'tcha, big man? What we have here is a rare opportunity for me to cut loose and show you just how powerful I really am.
** He then turns the tables and lets loose on Darkseid, knowing that he won't be killed right off, and easily kicks Darkseid's ass, sending him flying through several buildings to the other side of the city and then bashing him back down to the ground. Unfortunately, Darkseid then does this as well. Realizing he's outmatched physically, he switches to his technological superiority [[NegatedMomentOfAwesome and instantly defeats Superman.]]
** In the ''WesternAnimation/SupermanTheAnimatedSeries'' episode "Knight Time", [[ItMakesSenseInContext while Superman poses as Batman after Bruce Wayne disappears]], he's forced to hold back as he fights Bane, but after Bane is led to think he's won, Superman stops holding back. It's both hilarious and awesome at the same time.
* General Grievous at the end of ''WesternAnimation/StarWarsCloneWars''. You thought he was tough with two arms? Well, now he has four.
* ''WesternAnimation/TheSimpsons'': Marge Simpson, of all people, invokes this trope in the Vancouver Olympics episode. Her arm is sprained in the second-last match, and is about to give up. [[spoiler:Then, Homer notices her skill with her other arm, which Marge remembers is actually her dominant one]].
* ''WesternAnimation/SpongeBobSquarePants'' has an example where he gets a splinter in his thumb while working and is trying to hide it in order to avoid being sent home for injury on the job. When he sees it's hindering his ability to flip krabby patties, [=SpongeBob=] switches the spatula to his other hand and reveals that he's ambidextrous (able to use both his right and left hand).

[[folder:Real Life]]
* Rafael Nadal, an 11-time Grand Slam champion in UsefulNotes/{{tennis}}, is right-handed, but he learned to play left-handed for purely strategic reasons; there are not too many lefties in tennis so opponents can find it difficult to adjust to playing against. In particular, it helped him become the only player to consistently beat Roger Federer (arguably the greatest player of all time), because Federer's one-handed backhand is vulnerable to Nadal's lefty forehand.
* In a boxing match on November 4, 1947, left-handed fighter Mike Collins emerged from his corner in a right-handed stance and then shifted into a left-handed stance, flooring his opponent and winning the match in four seconds.
* It's common knowledge that professional wrestling is largely a staged fight but what ''isn't'' common knowledge is that a large part of the training is learning how to hold back so as ''not'' to seriously injure the opponent, and for the wrestlers to willingly cooperate in order to reduce injury. In essence, every match has the wrestlers fighting "left handed". While professional wrestling moves are meant more for show than for actual practical application, often telegraphing most severely, it's safe to say that if some of those moves were performed in earnest, they would hurt. ''A lot.''
** To further illustrate this point, a lot of old school wrestlers-turned-trainers (such as Stu Hart) were legit amateur wrestlers and made a point of training their students to really wrestle and grapple fight.
* Billiards and particularly Snooker players sometimes switch hands to avoid awkward stretching across the table; some even actively train to become near-ambidextrous. However, only superstar [[TroubledButCute Ronnie O'Sullivan]] will sometimes play entire frames left-handed just to mess with his opponent's head. Opinions differ on whether this is pure awesome or just jerkassery. O'Sullivan once received a formal complaint about being disrespectful after playing left-handed. In response he claimed that he could play left-handed better than his opponent could play right-handed. He wasn't disciplined because he proceeded to play a three games in a row against a professional, left-handed, and won all three.
* Many left-handed people will have found themselves in situations where the opposite applies. For whatever reason you will be forced to do something with your right hand and because of this will generally be pretty bad at it, but then when you get the chance to use your left hand you will surprise everyone at how much better you are. A common example is using something designed for right handed people, then switching to something that can be used by either hand.
* A famous example is the "Rumble in the Jungle" fight between heavyweight boxers UsefulNotes/MuhammadAli and George Foreman. While everyone knows the story now, back then, people had no idea Ali was intentionally holding back and letting Foreman pound him on the ropes. He told everybody who would listen that he was going to dance and make Foreman look silly, but he was bluffing. He knew Foreman was too powerful to stick and move, because all it would take was one good shot by the big man to seriously hurt him. So he laid on the ropes until Foreman punched himself into exhaustion, then he knocked him out. Ali, afterwards, called the tactic the "rope-a-dope".
* Justified in the case of Károly Takács, an Olympic pistol shooter. He was already a world-class marksman when he suffered injuries to his right hand whilst handling a faulty grenade, whilst serving in the Hungarian Army. Determined to continue his shooting career however, he trained using his left hand and eventually went on to win two Gold Medals in the 1948 and 1952 Olympic Games.
* A similar case to this is the pianist Paul Wittgenstein, who lost his right arm in World War I, but continued his pianist career by commissioning works for the left hand alone by many prominent composers of the day, most notably Maurice Ravel's ''Piano Concerto for the Left Hand''.
* Also [[https://www.youtube.com/watch?v=U5Y460dZtGY this talent show performance.]]
* Common when nations with a superior technologically advanced military, attacks a nation with an inferior and primitive military to keep civilian casualties low or avoid total destruction of the country's limited infrastructure. Sometimes an objective becomes so important to neutralize, they unleash their full might to achieve it (innocent bystanders and collateral damage be damned), showing they could actually [[CurbStompBattle annhilate everything if they really wanted to]]. Moreover they never seriously consider using a NukeEm to just [[ThereIsNoKillLikeOverkill end the conflict in 15 minutes]].
* Used in UsefulNotes/{{Cricket}}. While a batsman's handedness is usually known to everyone by the time they get to top level, sufficiently nimble ones can switch stances while the bowler is in mid-bowl (mid-pitch). Since players on the field in cricket are positioned asymmetrically, this completely throws off the attempted formation.
* Golf, a sport in which left-handed play is pretty rare at the top level, has some illustrations of this trope.
** Played straight by Phil Mickelson, probably the most successful left-handed player in history; in golf circles, if you make a reference to "Lefty", everyone knows you're talking about him. Mickelson does ''everything else'' right-handed -- he learned to play golf as a child by mirroring what his father did while facing him; his father played right-handed.
** An inversion: All-time great Ben Hogan was actually left-handed, but played right-handed.
** Both played straight and averted by 2003 Masters champion Mike Weir. Like Mickelson, he's a natural righty, but learned to play golf as a lefty. In Weir's case, it was largely because he was a left-handed shot in his first sport of [[UsefulNotes/IceHockey (ice) hockey]] (he's UsefulNotes/{{Canad|a}}ian).[[note]]Handedness in ice hockey is based on the side from which a player normally shoots. Most Canada-trained players are taught to play with their dominant hand on top of the stick, meaning that forehand shots will come from the side opposite their dominant hand. This is thought to be the main reason why left-handed golf play is much more common in Canada than in almost any other country.[[/note]] While he enjoyed considerable junior golf success as a lefty, he had people telling him that he might be an even better player if he switched to right-handed play. He decided to write a letter to a pretty well-known golfer whom he had met at an exhibition when he was 11... none other than UsefulNotes/JackNicklaus. [[RedBaron The Golden Bear]] quickly wrote back, telling Weir that if he felt comfortable playing left-handed, he should stick with it. Weir plays left-handed to this day.
* As part of a prank, [[https://www.youtube.com/watch?v=F3FZLTpJREY a nerdy girl asked two new Muay Thai trainers at a gym to spar with her]]. She goes a few rounds letting them think she's an unskilled newbie before proceeding to school them, since that nerdy girl is actually Germaine Yeap, a professional Muay Thai fighter.
* Michael Vick, considered one of the most athletic Quarterbacks in the history of the NFL, and one of the biggest {{What Could Have Been}}s, throws left handed, despite being right handed. He was so good as a child, the neighborhood kids made him throw with his left hand, and it stuck.
* This is a common strategy used by chess hustlers. They'll play a few games with someone with no money at stake, and play deliberately poorly to make the opponent think they're weak. Then they'll get them to make a bet on the next game, and start playing for real.
* On a broader sense, few military powers respond with the full strength of their arsenal to threats anymore, least of all the nuclear ones. The reason is that doing so would result a lot of neutral civilian casualties. Perhaps one of the greatest illustrations of this trope comes from Fallujah when over a hundred insurgents barricaded themselves in a booby trapped three story apartment building. The US Army's response was to simply blow the whole thing up using a single tank since there was no risk to civilians. In less than an hour all the insurgents were dead with no other casualties.
