* The absurdly skilled leads (both {{Badass Longcoat}}s) in ''Manga/{{Trigun}}'' and ''LightNovel/TrinityBlood'' often deliberately give off an air of incompetence and cowardice...which only serves to make it even ''more'' awesome when they finally [[LetsGetDangerous cut loose at the height of their powers.]]
* Raiha and Joker in ''Manga/FlameOfRecca''. Kurei even compared Raiha to a Japanese warrior who pretended to be an idiot, to make others underesrimate him.
* The titular character of ''Anime/IrresponsibleCaptainTylor'', who constantly kept everyone (including the audience) wondering whether he was a tactical genius or just incredibly lucky.
** There are strong reasons to think (and many fans do so, indeed) that he actually is an illuminated bodhisattva. If this interpretation is correct, the surreal opening animation actually shows the moment of his Buddhist epiphany, and Tylor's real ultimate goal all along the series would be to bring enlightenment to his crew. (Especially to Yamamoto, an impressive success!)
* ''Manga/RurouniKenshin'':
** Himura Kenshin in tried to pass himself off this way in the first episode, but was eventually found out. He continues to act like an idiot whenever he's not fighting at least for the first half of the series. He usually manages to maintain the masquerade until someone familiar with his past [[TemptingFate tries to force him]] to [[LetsGetDangerous fight properly]].
** The puppet master Gein also plays to be really stupid as his alter ego Iwanbō.
* Genma Saotome from ''Manga/RanmaOneHalf''. He behaves like a lazy, thieving, sadistic, cowardly, gluttonous, etc etc and a total waste of space. And maybe he is. But the one time Ranma seemed about to outpace him, Genma asserted dominance over Ranma with psychological attacks (the "Hell's Cradle Technique"). Also, Genma managed to create two new martial arts forms from scratch that would be at home in the ''Manga/{{Dragonball}}'' stories, and once managed to prove himself the near-equal of his evil master Happosai by manifesting Godzilla-scale powers for a brief moment.
* ''Manga/FullmetalAlchemist'':
** Lt. Colonel Hughes hides [[KnifeNut his deadly skill with knives]] and investigative intelligence behind a public persona of a ditz who's always shoving pictures of his daughter in front of anyone and everyone. Or maybe he just is a ditz who adores showing pictures of his daughter and is an awesome [[BunnyEarsLawyer investigator at the same time]]. In the Brotherhood OVA, he reveals that part of why he created this persona is because he doesn't want to burden his family with what happened in Ishval.
** To an extent so is Major Armstrong [[Anime/FullmetalAlchemist in the anime]], though he hides his intelligence and investigative skills behind a meat head persona rather than the classical ditz. His tendency to rip his shirt off at every opportunity [[BunnyEarsLawyer is more an aspect of his personality]].
** Fuhrer King Bradley beats them both, though, ''especially'' in the manga. While those who served in the Ishval conflict know or at least have a hinted clue just how vicious he can be, he starts out being presented to the audience and the two protagonists as being a harmless kook who likes avoiding work and giving people melons as gifts, which makes the revelation of his true personality and the combat skills that go with it that much more terrifying. There's a very, ''very'' good reason why [[spoiler: his other name is Wrath]].
** Roy Mustang. A good-looking soldier, who only cares for promotions [[spoiler:and has sworn to protect his comrades and underlings using his position and power]]. He dates several girls at the same time, [[spoiler:using this so that people wouldn't notice him too much]]. He constantly goes to a brothel/pub with a lot of girls, [[spoiler:(to gain information from the girls. Also, the pub owner is his foster-mother]]. He uses military phones to call his girlfriends, [[spoiler: in order to direct the 'girlfriends' in coordinated attack]]. Finally, his assistant has to keep him in check, [[spoiler:read: stop him from going too far with/away from his idealism]]. Sounds like a [[JerkJock bastard]], doesn't he? [[spoiler:[[JerkWithAHeartOfGold Good thing]] [[JerkassFacade he isn't]].]]
** In truth all soldiers in Mustang's group except Hawkeye (who doesn't hide her smarts) are eligible, because every soldier in ''FMA'' has a [[TheMasquerade mask]].
** Van Hohenheim. This trope and CrouchingMoronHiddenBadass pretty much embody all of his character before his [[spoiler: immortality is revealed and he pretty much turns into a BadassBookworm with a side order of [[BadassLongCoat awesome]]]].
** Ling Yao is sort of like this, although his undignified goofiness does seem like a natural part of his personality that he just deploys strategically. He first appears as an obnoxious, greedy FunnyForeigner who tries to weasel his way out of paying for damage he himself caused ([[CrowningMomentofFunny "So sori, I no undastand much language of zis countri, bye bye now!"]]), and then he pulls out his sword and ''hands people their asses''. He even manages to survive a fight with [[spoiler:Wrath]] ''while'' carrying an injured Lan Fan.
** Edward Elric himself. He acts like a hot-headed moron, and is especially stupid at times, but then he figures out something that men ''twice'' his age couldn't do, passing the State Alchemy Exam at 12, which normally takes up till the age of 20, and learning how to do Human Transmutation.
** The man who taught Mustang some of his ObfuscatingStupidity, Lt. General Grummon. Hiding behind that chess loving, female officer harassing, general funny old man personality, is the mind of a cunning [[TheChessmaster chessmaster]].
* ''LightNovel/{{Slayers}}'':
** Xellos tends to give an impression of amusing if annoying harmlessness as long as his eyes remain closed, hiding his true, sinister nature.
** Gourry himself would be the textbook example, especially in the original novels, where he's a DeadpanSnarker who likes to pass as a [[DumbBlonde Dumb Blond]] for fun and profit. In the anime -- [[TheDitz not so much]]. Though he still [[DumbassHasAPoint get]] some good moments.
** The inspector in Slayers Revolution seems to be approaching TooDumbToLive territory in the beginning, until it is revealed that it is all just an act to capture his real target.
** Lina could arguably be this since her general status is twelve steps ahead of everyone or not. The "or not" usually happening because she doesn't actually care about the situation involved. However, it's hard to tell which is the case since her general behavior doesn't change at all between being in left field or out-chessing everyone else.
* ''Manga/{{Naruto}}'':
** In his first appearance, Kakashi "falls" for Naruto's juvenile prank, making his charges think he's a moron. Of course, he proves them wrong later in the episode...
** And while that put him out of the "stupid" category, Kakashi's next four opponents (counting Haku, who observed and tried to deconstruct his fighting style so that Zabuza could later kill him) all fatally underestimate him in three different ways, just to drive the point home that Kakashi has whole ''layers'' of this going just by force of habit. Given that Kakashi is fairly infamous among Konoha's enemies, the fact that he's ''still'' able to get enemies to underestimate him is rather impressive.
** There's also Shikamaru, who's a borderline case. He really is smart, and when he wants to buckle down, [[BrilliantButLazy he's an unparalleled strategist, but he's extremely lazy.]] According to his sensei, Asuma, he felt that even moving his pencil in his class was too much trouble. When Asuma got Shikamaru to play a game that was actually a hidden IQ test, he discovered Shikamaru has an IQ of over 200 (for comparison, Albert Einstein had an IQ of 186, which made him smarter than 99.9999% of all humans). Still, a standard battle involving Shikamaru usually plays out like this: Shikamaru gets his ass handed to him for 95% of the battle, and just as the enemy is about to close in on him, he reveals that he's known their plan all along, and was just messing with them.
** [[spoiler:Tobi, the Akatsuki's comic-relief member]], has been using this tactic since his first appearance. He's really [[spoiler:Obito Uchiha, the former teammate of Kakashi, and both TheManBehindTheMan and BigBad to boot]].
** Rock Lee's debut featured him also pretending to be an inexpert rookie moron so Team Guy can go around before the Chuunin exams without standing out. But when a fight breaks in, Lee can't help himself and promptly stops the fisticuffs, leaving everyone surprised at how an apparent weakling was so skilled.
** To a lesser extent, Lee's teammate, Neji. Though an ArrogantKungFuGuy (to the point where he's practically the TropeNamer) in his early appearances he hid the fact that he had managed to master many of his clan's most advanced techniques and even improve on them, just on basic theory alone.
** [[TheObiWan Jiraiya]] definitely displays this trope. At the start of battles, he acts like an idiot and makes great, unneeded moves, to throw off the enemy to underestimating him. When they attack...he attacks with utmost seriousness to put them down in the most efficient way possible. Outside of battle, it's hard to take him seriously due to his perverted actions and his tendency to hang out in the RedLightDistrict. As it turns out, a large number of contacts in his spy network can be found in said districts.
* ''Anime/YuGiOh'':
** Pegasus feigns intimidation and hopelessness when Kaiba duels him, and as a whole comes off as a real goof who has trouble taking ''anything'' seriously. The reason he acts this way is to keep his opponents off-guard when he reveals himself as a master duelist (he ''is'' the guy who made the game after all). It is also implied that Pegasus might act like this just because he knows it annoys people. Even if people don't buy the act, the annoying part works perfectly. His deck is the same way, consisting of comical over-the-top "Toon" monsters that chuckle and make faces while attacking. [[http://www.youtube.com/watch?v=VhzrxopN_y8 Just watch]].
** In her first appearance, [[BrattyHalfPint Rebecca]] used a DeliberatelyCuteChild variant, playing up her "innocent child" image and talking to her teddy bear to hide her [[TeenGenius true skills.]]
** Mai also makes use of this trope. Pretending to be a BrainlessBeauty and FanGirl, she challenges Rex to a duel; if she wins, she gets his room. If he wins, he gets to spend the night with her. Severely underestimating her, he accepts her challenge. Some pages later, she kicks him out of his room.
* Hige from ''Anime/WolfsRain''.
* DarkMagicalGirl {{Ninja}} (yes) Freesia Yagyuu of ''Anime/JubeiChan'' hams up her Half-Russian heritage with broken Japanese and a vapid demeanor. In reality, she speaks perfect Japanese, and is frighteningly intelligent.
* Kumiko from ''Manga/{{Gokusen}}'' swings back and forth between TheDitz and the ActionGirl as a scene requires, even throwing in a little ClarkKenting to clue the viewer in as to which one she's trying to be.
* ''VisualNovel/HigurashiNoNakuKoroNi'':
** [[spoiler:[[CreepyChild Rika Furude]]]] is proven to be this in season 2, though in the original VisualNovel [[spoiler:her]] intelligence is hinted at much earlier in the TIPS.
** Also, Rena gives off the [[CuteClumsyGirl clumsy]], [[TheDitz ditzy]] feel, but she may just be the smartest of the gang. She shows incredibly, almost absurdly, good detective skills when [[spoiler:Satoko and Rika disappear in Watanagashi-hen]] and made up an almost believable theory about Hinamizawa in [[spoiler:the Atonement chapter...until she lost it and started talking about aliens.]]
** Keiichi is also an example of this as before he moved to Hinamizawa he was an InsufferableGenius with no friends that was picked on constantly in school (which lead to his unfortunate stress reliving activity). After moving he decided DumbIsGood and began acting like he is known for in the series; however his intelligence sometimes shines through his act and he appears simply BookDumb. And he's not BookDumb at all. Several scenes show him tutoring the others, including the older [[CoolBigSis Mion]], and it's implied he gets the best grades of the group. He has learned by the start of the story to not put on an act just to feel good about himself and impress others, so he acts the way he does because that's how he genuinely is. So it's really more like he completely lacks common sense. Given [[TownWithADarkSecret the setting]], he [[DysfunctionJunction fits in]] right in right away.
* Another shonen protagonist of this persuasion is Taikoubou of ''Manga/HoushinEngi''. In almost every situation he adopts a manner that is either agonizingly lazy or comically bizarre, but he is in truth an adept and cunning tactician.
* ''Manga/{{Bleach}}'':
** Isshin started the story apparently completely oblivious to the fact that his son had become a Shinigami, regularly left his body under the possession of a spirit and had sentient toys in his room and a girl living in his wardrobe. Then it's revealed that Isshin is a captain-class Shinigami and has aware of his son's activities all along.
** Urahara plays the role of an eccentric shop owner to cover for his real self, a ridiculously skilled scientist and inventor, a former Shinigami Captain and an ex-warden of one of Soul Society's highest security prisons which required him to be able to subdue all prisoners with his bare hands alone. His idiot act seems to be habit now, as lampshaded by Renji who points out no-one's going to believe Urahara's claim that he doesn't have bankai when everyone knows he used to be a captain and invented a new method for obtaining bankai in a record-breaking three-days.
** Squad two lieutenant Omaeda looks and acts like an UpperClassTwit until he fights one of Barrigan's [[EliteMook fraccion]]. During the fight, he manages to use his apparent stupidity to trick his opponent into using his resurrection ability, then demonstrating [[FlashStep exactly]] ''[[FlashStep why]]'' he's second in command of what basically amounts to the Soul Society special forces.
** Pesche and Dondochakka's goofiness hides the fact they were once the fraccions and protectors of the former Espada, Neliel. Current Espada [[MadScientist Szayel]] even admits that their CombinationAttack would have killed him if he hadn't had a chance to analyze their powers beforehand.
* Haruko Haruhara from ''{{FLCL}}'' uses the [[{{Cloudcuckoolander}} façade of a goofy policewoman from space]] so that no one questions deeply what she's doing here in the first place and what her goals are. In the last episode she finally reveals what she was planning, to absorb the powers of Atomsk, the Pirate King. [[spoiler:She almost succeeds, too, but Atomsk eventually escapes, so she leaves to pursue him again.]]
** Or something. It's not like you really understand what she wants after watching the show.
* In ''Idaten Jump'' we're introduced to Arthur, a mild-mannered and geeky-looking painter with NerdGlasses who enters the MTB tournament and becomes a ButtMonkey among fellow competitors. It turns out that [[spoiler: Arthur is not only [[BeautifulAllAlong a very handsome blond]], he's an ''excellent'' biker and a good friend of the local WrenchWench Yuki, who pretended to be dumb to hide his identity as a member of the guerrilla against Gabu, the child dictator and leader of the Shark team.]]
* He's a lazy, tanned Buddhist monk in his late 30's with a stubble, whom his wife treats like a younger brother and his kids (both [[TroubledButCute 12-year-old son]] and [[CoolBigSis 19-year-old niece]]) treat with not too much respect, and who often [[LovableSexManiac ogles attractive girls]] much to others' embarrassment. But give him a racket and/or bring him to a tennis match...He'll either beat the crap out of you at the courts or give you the most acute comments about the current game. That's Nanjiroh "The Samurai" Echizen from ''ThePrinceOfTennis'' to you (as in the title character's ''dad'').
* One early look at ''Anime/{{Mai-HiME}}'''s Midori Sugiura would likely lead one to think: "[[{{Dojikko}} Clumsy waitress]]...[[OneOfTheKids ditzy teacher]]...I could probably take her in a fight". However, once she [[JumpedAtTheCall gets into her Element]], she can (and will) kick ass with flair, occasionally exhibiting leadership qualities that would make Storm proud.
* In ''LightNovel/FullMetalPanic'', Melissa Mao reflects back to her initial encounters with Sousuke and Kurz: she was sent to scout the training camp they were in for candidates to recruit to Mithril. Both Sousuke and Kurz, mistrustful of the mysterious organization sponsoring their training, deliberately underperformed: Sousuke was content to maintain a level of careful mediocrity, but [[LovableSexManiac Kurz]] went the extra mile and staged an attempted sexual assault on Mao to make ''sure'' she'd strike him from her list. When a mission came in and most of the other members were captured, however, both of them were obliged to demonstrate the full level of their considerable skills.
** Gauron is {{lampshaded}} to have the habit of doing this to fool his potential prey...at least temporarily, before his psychotic, AxCrazy tendencies take over. As Kalinin described him in ''Kyokuhoku Kara no Koe'', "When you were fooled by his seemingly languid appearance, he would suddenly display his determined and violent nature."
* Thorkell in ''VinlandSaga'' has such a goofy grin on his face most of the time you can easily forget he's a killing machine. That, and his good-natured ribbing of both friend and foe make him come off as downright harmless. Until he splits a man in two with a single blow, or crushes a guy's skull for speaking out of turn. Just look out if you make him really angry, 'cause he will [[MemeticMutation punch your horse to death]]. Yep, a bag of laughs that Thorkell.
* Konoka Konoe of ''MahouSenseiNegima'' tends to play TheDitz, and while there's no denying that she's a bit flaky, she often seems to know a lot more than anyone gives her credit for. For example, when her [[ThePowerOfLove love for]] [[LesYay Setsuna]] causes her [[EleventhHourSuperpower ridiculously powerful]] [[HealingHands healing]] [[WhiteMagic magic]] [[CrouchingMoronHiddenBadass to suddenly manifest]] at the end of volume 5 of the manga, she acts as if she has no clue what just happened, even though we saw her summoning up magic for a spell (which she aborted) early in volume 4.
** And then we have Jack Rakan. Sure, he's powerful, but he's just a [[BoisterousBruiser overly rambunctious]] [[DirtyOldMan skirt-chaser]] underneath all the muscle, right? [[spoiler: Wrong. So, so wrong. That happy-go-lucky attitude is born from the fact that he's been involved in brutal, life-or-death combat for over forty ''years'', so he can ''afford'' to act goofy because there is honestly nothing that poses a serious threat to him at this point. His actual intellect is shown off fully in the magical world tournament: after Negi develops a technique that literally let him ''turn into lightning'', increasing his speed to unbelievable levels...it takes Rakan exactly one observation of said move to analyze it, find all the flaws, and devise counter-techniques which allow him to effortlessly and utterly kick the crap out of 'invincible thunder god Negi'.]]
* Kyon in ''SuzumiyaHaruhi'' (Much more obvious in the light novels) often appears as a BookDumb student no better than a janitor. Granted, he cannot comprehend Koizumi's theories ([[ViewersAreGeniuses Can you?]]) or Haruhi when she's at deducing and solving math problems. He doesn't even want to listen. However, he usually knows ''exactly'' what's going on, especially if it comes to figuring out other characters' hidden motives and feelings. Being the UnreliableNarrator he is, he may even fool the reader. Also made more clear through LittleProfessorDialog; he drops a suspicious number of references to concepts he claims to know nothing about.
** To quote the man himself, when he alone solves the fake murder (In the novels):
--->'''Kyon:''' "And I may not look like it, but I do pay attention to things that matter. [...] Don't underestimate me."
** It's strongly implied (throughout the anime, at least) that he's just too ''[[BrilliantButLazy lazy]]'' to act smart.
** The whole SOS brigade sort of counts here. Kyon suspects Koizumi of doing this; Koizumi suspects Mikuru of doing this. And no-one outside the brigade pays much attention to Yuki, just sitting in a corner reading.
* [[spoiler: Suzuko Tashirou]] aka Norie Otobe from ''GlassMask''. Who would think that the nerdy girl with glasses and a Kansai accent would [[spoiler: be such a cruel [[ManipulativeBastard Manipulative Bitch]], able to play a frighteningly good {{plan}} to have Maya Kitajima kicked out of the acting scene?]] Unfortunately for her, [[spoiler: Maya's rival Ayumi Himekawa was NOT amused when she found out...]]
* Mrs. Ketchum (Ash's (hot) mom) in ''{{Anime/Pokemon}}'' is another borderline case. She's been a single mom for as long as the anime has been on the air, but it's later revealed she was a student of Professor Oak's, and an exceptional one, at that. Chances are she just comes off as uninformed since she had to put her studies, and such behind once Ash was born.
* Though more of an ExtremeDoormat subversion, almost all of the characters in ''Anime/RevolutionaryGirlUtena'' believe that Anthy has absolutely no thoughts of her own. ''Right''...just like Akio's a [[ManipulativeBastard good guy]]...
* [[KenichiTheMightiestDisciple Kenichi]] of all people pulls this off in chapter 307. [[spoiler: He already figured out that Kushinada is a member of YOMI. He's trying to win her over without a fight because he WouldntHitAGirl.]]
** Also in ''Kenichi: The Mightiest Disciple'', there's Apachai Hopachai, who despite his childish personality, can and HAS murdered dozens of people with his bare hands, being a master of Muay Thai. In fact, it has been explained that he completely lacks the ability to hold back, and striking with lethal force is reflex for him. He may act like a baby, but hope to God that you don't find his BerserkButton.
** He's never ''actually'' killed anyone, though. Well, unless you count Kenichi (by accident).
** With Apachai, it isn't so much ObfuscatingStupidity as a ''huge'' case of CrouchingMoronHiddenBadass.
** While setting to rescue Miu, Kenichi and Sakaki meet John, an overweight mercenary who gives them aid until he reveals himself as [[spoiler: Furinji Saiga, who is also Miu's father and YAMI's leader]]
* Bit Cloud, of ''{{Zoids}}: New Century Zero'' makes it hard to tell whether he's a BunnyEarsLawyer or CrouchingMoronHiddenBadass or even IdiotHero, but the most common diagnosis is Obfuscating Stupidity. Interestingly, his guise is to act as a GeniusDitz, with the incredible knowledge of Zoid parts and mechanics a scrap merchant should have but without the practical knowledge to survive a more difficult fight or even the complexities of living in the same building as the {{Tsundere}} GirlWithPsychoWeapon. Then he starts beating skilled opponents through complex strategies like wasting ammo on a cliff face to force a long range focused opponent into mêlée, and he starts looking practical in battles through [[TheFool luck]] or otherwise, even if he'll eventually find himself on the wrong end of a [[MacrossMissileMassacre Weasel Total Assault]]. Then the team's tactician realizes that said {{Tsundere}} only fights best when firing missiles at wherever Bit is standing.
* Nineteen-year-old Emperor Shi Ryuuki in ''SaiunkokuMonogatari'' is initially called "stupid emperor" by members of his court disgusted by his complete lack of interest in ruling his empire, and his habit of spending his days hiding from court officials and spending his nights sleeping with other men. When properly motivated, however, Ryuuki reveals that he has a ''much'' defter hand for political intrigue than anyone suspected, and that there's a very good reason that he is the only one of six brothers to survive the imperial court long enough to take the throne; he cultivated the "stupid emperor" image as a survival mechanism, and refuses to rule in the hopes that his exiled older brother Prince Seien will return to take his place.
** After Shuurei convinces him to get serious about governing Saiunkoku, Ryuuki ''keeps'' playing the idiot so that she'll stick around for a while longer to tutor him. As you can imagine, Shuurei is ''furious'' when she finds out.
* Conan of ''Manga/DetectiveConan'' repeatedly makes a very awkward use of this to disguise his investigations and artificial Creek Moments. In general, he gets away with it more because of him looking like a child than his questionable acting skills.
** Also, Jodie (the undercover FBI agent pretending to be a teacher) pretends to be far less fluent in Japanese than she actually is; Heiji picks up on this and calls her out on it.
** Eisuke Hondou, while [[CuteClumsyGirl genuinely clumsy]], has exploited this weakness to obfuscate some of his scooping behaviour.
* Dr. Shamal from ''Manga/KatekyoHitmanReborn'' comes off initially as being a rather ditzy, [[HandsomeLech womanizing lech]] that is completely incompetent. And then it's later revealed that he's strong enough to have managed to inject a virus into Hibari at the exact same moment Hibari hit him without Hibari even noticing.
** Rokudo Mukuro also does this to some extent during his first meeting with Tsuna, pretending to be a helpless boy who was captured by...Rokudo Mukuro.
** Tsuna's [[DisappearedDad father]] Iemitsu Sawada came across as a loving husband who spent all of his little time time home eating, drinking, and sleeping. [[spoiler: He's Vongola 9th's chief advisor and implied to be a powerful mafioso.]] Later in the Curse of the Rainbow Arc [[spoiler: he used Tsuna's perception of him as a ditz to throw Tsuna off balance and defeat him.]]
* Dr. Stein from ''SoulEater'' plays this trope during his first appearance and meeting with the protagonists. The way he appeared didn't exactly impress them, rolling his chair backwards out the door and falling over. And then doing it again. Of course, he turns out to be a super [[{{Badass}} badass]] with sadistic tendencies.
** He plays with it throughout the series, really. Any time his glasses are perfectly opaque and round (not to be confused with [[ScaryShinyGlasses shiny]]) a la NerdGlasses, the next words out of his mouth are probably going to be interesting, if not downright dumb.
** There's also [[GrimReaper Shinigami]]. At first, he seems like a fairly silly Dumbledore-esque teacher, which clashes with the fact that he's, you know, ''Death.'' And then you meet his Scythe, who is a womanizing twit who spends his time alternating between patronizing a whorehouse and crying over his estranged daughter, and it all seems to make sense. And then, several chapters later, once you've gotten acclimated to the idea that Shinigami is a silly old fool long past his prime, we realize that [[spoiler: he once imprisoned an insane subordinate/disciple by ''ripping off the guys skin, turning it into a bag, and imprisoning the guy's body in it,'' and is perfectly willing to do it ''again'' once said guy escapes. And if the latest chapters are any indication, he's a full-on Eldritch Abomination as well.]]
*** It's stated that he puts on that facade so that he doesn't freak his students out
* [[spoiler:Prince Parion]] of ''Orguss 02'' feigns idiocy for the first few episodes of the OVA - until he orchestrates the murder of his half-brother and the EvilChancellor who killed his father, assuming the throne himself. He then goes on to attempt a global [[strike:takeover]] [[WoobieDestroyerOfWorlds omnicide]] using a HumongousMecha.
* Czeslaw Meyer from ''LightNovel/{{Baccano}}'' does a bit of this, deliberately playing up an AdorablyPrecociousChild image, to mask or downplay the fact that he's at least [[ReallySevenHundredYearsOld two hundred years old]] ("What? Did I just say something that wasn't very child-like? You must be thinking too much").
** Later novels suggest that maybe, just ''maybe'', [[spoiler:Isaac and Miria might be playing up their legendary stupidity]].
* Ukyo in ''SamuraiSeven'' seems an idle, childish, vain hedonist...and he is, [[spoiler: only he is also brilliant enough to successfully earn the right to be the Emperor's heir when all the Emperor's other clones had failed. Clever enough, ruthless enough, to assassinate and usurp the Emperor afterwards, and no one suspects him.]]
* Commander Doolittle in ''MarsDaybreak'' comes across as being either extremely lazy, extremely incompetent, or both. However, he comes the closest to actually trapping the ''Ship of Aurora'', and didn't need an entire fleet to do it.
* Ma Gangryong from ''{{Veritas}}'' spent his first few weeks at NinjaSchool mouthing off to people stronger than himself, and then getting beat up. He later reveals that he mouths off because it makes the highly refined fighters around him angry, and thus sloppy, which is his style. He also points out that after having lost so many fights, everyone thinks he's weak, and that they'll continue to think so long after he's surpassed them.
* In ''Manga/OnePiece'', Luffy does do some pretty silly things once in awhile (OK, almost all the time), but he has shown an amazing insight into certain things. Like with Alabasta, he pointed out that in order to stop the rebellion, they should stop Crocodile and not the pawns that he tricked into rebelling. Then, at Thriller Bark, with some of the crew having lost their shadows and worried about confronting their own shadows, Luffy simply reminded everyone that by beating Moria, everyone's shadows will come back. Which also sorta counts as WhenAllYouHaveIsAHammer since he's pointed out that all pirating skills are beyond him, he just has to be able to apply his one skill the best: beating the crap out of the strongest guy who happens to be in their way.
** Maybe his simple mind lets him see to the heart of things. [[FridgeLogic I don't know.]]
** There has to be some reason that he's still the captain, when he's obviously surrounded by people smarter than him.
*** He's a pretty good judge of people as well. And while he may be less ''smart'' than anyone on his crew, he is perhaps the wisest of all of them. Luffy's simplest outlook on life allows him to see things as they are without the complexities muddling everything up for him, so while his crew may be trying to figure out a personal problem with all the complexities in mind, Luffy's the one who usually points out the simplest and most logical solution.
** Probably the earliest example of how intelligent Luffy can be is when the ''Going Merry'' is about to crash into Laboon (the insanely huge island whale) at the bottom of Reverse Mountain. While the others are trying (ultimately in vain) to steer around it, Luffy goes below deck and ''uses the cannon as a retrorocket''. So instead of smashing the boat to bits, the only thing that breaks (unfortunately) is the figurehead...his "special seat".
** Zoro too has his moments. Usually, he's seen sleeping, drinking or off fighting. But at Alabasta, he was the one who thought of the white bandage for them to separate them from the enemy. But the real brilliance comes when [[spoiler: there was a symbol of an X underneath the bandage. If one of the enemy pretending to be them can't do that, then they would know it's the enemy.]] Even Sanji calls him out on it, thinking that it was a little suspicious that someone like Zoro was able to think of something so clever like that.
*** While Luffy and Zoro more have screwy personalities that make it seem impossible they actually possess any form of brain, Sanji perhaps is the only one who puts on the stupidity intentionally. The best strategical mind on the Strawhats, he often looks just far enough ahead to pull a vital string that ends up saving the lot of them down the line. See in Water 7 when he realized Robin would be leaving via sea train and ran off early to stow away when everyone else was still messing around trying to figure out what to do. Ask him what he was doing beforehand? He has to go "see about a lady". Faced with the second best fighter in Croc's posse, and confronted as to whether or not he was the code-named orchestrator of the Straw Hats' escape? No, he's "just a simple sea cook." He stays out of sight, doesn't give his name, acts like an idiot (except in regards to his nature as a ChivalrousPervert; that part isn't an act) and generally ends up, as Zoro pointed out mockingly, in the convenient position of being a {{Badass}} (Zoro left that part out) who everyone takes to be "pirate A" That does have the unfortunate side effect of his bounty poster though.
*** One of the best examples is at the climax of the Enies Lobby fight, when Sanji disappears shortly before the start of a melee against captain and vice-admiral marines for several chapters. When he comes back (pulling off a BigDamnHeroes moment as he does so, saving their allies from the escape ship that the Marines just blew up) Zoro chews him out for ditching them in the middle of the fight. Shortly afterwards, when they get another method of escape but are surrounded by nine battleships, [[spoiler:it turns out Sanji sabotaged the Gates of Justice, making them close so that the whirlpools would be restored and the Marines would have to focus more on staying afloat than attacking them. Meanwhile, they and their much smaller ship can simply ride the whirlpools out and escape.]]
** Speaking of Water Seven, its mayor, Iceberg, put on a good enough show of Obfuscating Stupidity that the arc's villains, spies who had been stationed near him and included his secretary and two of his most trusted shipwrights, couldn't muster the confidence to make an overt move for five years, when their deadline forced them into action.
* In ''Manga/AxisPowersHetalia'', during the WWI scene, Germany ''thinks'' that North Italy is trying to use this on him. He's wrong, because North Italy really is TheDitz.
** True, Italy is TheDitz, but he's also ''hundreds of years old''. He actually did invoke this when he was a kid, pretending to fall for a rich man's bribe of candy but then denying him what he wanted anyway.
** Actually, most of the Hetalia characters are probably this in some way. France acts llike a narcissic flamboyant pervert most of the time, but he's been shown to have HiddenDepths. America can't read the atmosphere, but he does so intentionally - he could if he ''wanted'' to. Spain is a clueless dork, but has a scary side to him.
* Hellbat in ''TransformersVictory'' acts like a devoted and none-too-bright servant, but is in reality is waiting for just the right moment to overthrow Leozack and Deathsaurus. Since Leozack also wants to overthrows Deathsaurus...
* Most of the time, Shigure from ''FruitsBasket'' seems to just be a lazy, lecherous idiot of a novelist whose hobby is playing evil pranks on his poor editor in order to avoid his deadlines. As a matter of fact, it turns out he was actually a ManipulativeBastard all along. And possibly also a lazy, lecherous idiot. His acting is so convincing it's tough to say just how much of it was Obfuscating and how much was real.
* Someone watching ''Anime/DarkerThanBlack'' who doesn't know about the [[FirstEpisodeSpoiler second-episode plot revelation]] is likely to be thinking something like "What the...''Li'' is ''the Black Reaper?''" when it rolls around. The act also works on other characters, since nobody thinks to suspect the [[{{Adorkable}} adorably clumsy and naive]] NiceGuy of being a {{badass}} superpowered assassin.
** It helps that, in the story, only a few people even know that said assassin even exists. That, and BK-201 rarely lets anyone get a good look at him when he is on the job.
* Recently, in ''LightNovel/{{Kampfer}}'' [[spoiler: Kaede]] has been shown constantly as the [[spoiler: InnocentBystander]] that [[spoiler: always gets into [[DistressedDamsel trouble]] and likes [[GenderBender female-Natsuru]]]], but [[spoiler: she is actually in league with the Moderators and has been [[TheChessMaster manipulating almost everyone into doing her bidding.]]]]
** [[spoiler: Seems more like it's a split personality style (the anime at least)]]
* While not as intelligent as MagnificentBastard Light or GuileHero L, Misa Amane of ''Manga/DeathNote'' is smarter than your average blonde [[TheDitz ditz]]. Although her impulsiveness almost gives her away and irritates Light, she did take reasonable precautions in an attempt to not leave evidence and is even arranges the meeting between her and Light right in front of L's nose. She even realizes that Light doesn't love her and that he is [[YouHaveOutlivedYourUsefulness using her and will possibly kill her]], ''[[PsychoSupporter she just doesn't care]]''; unlike the calm and collected Kiyomi Takada.
* Sakamoto Tatsuma from ''Manga/{{Gintama}}'' appears to be a [[TheFool fool]] almost every time he is on screen. But how can that be, when [[spoiler: he is one of the most successful businessman in the galaxy]]? Not to mention that a flashback shows him to be [[spoiler: a serious, intelligent former resistance fighter.]]
* ''PokemonSpecial'''s Mr. Berlitz commissioned Ignor and Phool to watch over Platinum, who mistook Diamond and Pearl for her bodyguards (I&P were supposed to be the bodyguards in the first place). Given their antics in the time you see them, coupled with their names being variants of the word "idiot", you'd think Mr. Berlitz was an idiot himself for entrusting his daughter to these two. Per this trope, looks belie talent, and the two are very capable battlers with their Burmy and Buizel, as Saturn had the misfortune of discovering at the Lost Tower. They initially appear to have their asses handed to them by Saturn (who isn't even actually there, using a device to watch the scene and command his Pokemon) when Burmy gets its coat knocked off and Buizel appears to be abandoned, but it was all part of the plan as Buizel used its tail to create a whirlwind of Burmy's leaves to block Saturn's camera. Effectively blind, Saturn can no longer command his Pokemon which then get taken out in one hit.
** Ruby is a terrible battler. When people are watching. Sometimes Ruby's damage control isn't thorough enough. Mr. Briney fully assessed the damage done to a Corphish that boarded his ship after he recovered from a bout of unconsciousness, and came to judge Ruby as a seasoned battler...only to dismiss those claims when the poor boy heaved over the edge of his ship. Then again, he's the "don't ask, don't tell" kind of guy. Then there was the girl caught in a herd of frenzied Grumpig that Ruby and Nana (Mightyena) shut down swiftly and efficiently - unfortunately for him, there wasn't enough time for him to cover up the damage before she pieced it all together...and even if he could cover it up, there was no way he was going to fool Sapphire.
--> '''Sapphire''': Any trainer would have sent his Pokemon leaping in, but no! Every attack hit those black pearls dead-on. That's not an attack by an ordinary trainer...\\
'''Ruby''': That's strange, Nana. What came over you?\\
'''Sapphire''': ''Cut the act!''
* Rio in ''{{Spiral}}'' seems to be a ridiculously cute {{Dojikko}}, but she's as good of a {{Chessmaster}} as all the other Blade Children, if not better. And has the same obsession with bombs.
* A lot of characters in ''{{Durarara}}'' but the one guy who stands out of all people is [[spoiler: Ryugamine Mikado. He seems like your typical NaiveNewcomer, right up until he demonstrates that he's successfully ''[[ImageBoard weaponized 4chan]]'']]. If even then, he still doesn't seem all that scary on a personal level, just wait until he starts [[spoiler:stabbing people with pens with a [[DissonantSerenity horrendous expression]] on his face.]]
* ''{{Grenadier}}'' - Though Rushuna comes across as TheDitz most of the time, pay attention to her more vapid remarks, then note how they all lie completely at odds with the competency she shows in other respects. She knows mathematics, in a society where educating women seems to be a fairly low priority, especially in such abstract concepts. She has a solid understanding of various general models of guns. Her analytical abilities are nothing to scoff at. She goes from laughing to serious as immediately as the situation demands. From that, it's easy to see that she's only '''pretending''' to be a scatterbrained bimbo, and her ditzy comments suddenly take on a new, [[DeadpanSnarker very sarcastic meaning]].
* In the series ''{{Anime/Monster}}'', we have Grimmer. Best shown right when first meeting the character, where he gives money to a swindler and, when someone tells him that, saying he never even noticed. Just a few scenes later, you'll find out he is much more well-informed than he appears to be.
* In ''DragonBallGT'', the evil dragon Naturon Shenron at first seems to be the most foolhardy of the the Seven Shadow Dragons, even seeming easy to defeat by tricking him into blasting himself. However, it turns out that it was just an act and that he's a lot more intelligent (and speaks a lot more sinister). He even pretended to be defeated as a means to trick the heroes so he could absorb one of them and become more powerful.
* In ''{{Working}}'', Aoi's behavior makes her seem to be very [[{{Cloudcuckoolander}} "out there"]], but she appears to be very smart and focused when you least expect it--for instance when countering Souma's attempts at blackmail.
* In a manner of speaking, ''TengenToppaGurrenLagann,'' the ''show itself,'' qualifies. It starts off with a bunch of almost roly-poly characters who look goofy and many of whose actions seem to be self-parody (remember Kamina calling himself [[RatedMForManly "the ultimate in strength and masculinity"]]?). In fact, some people who only see the first couple of episodes actually complain about the show's [[IdiotHero supposedly]] [[TagalongKid stereo]][[MsFanservice typical]] [[StrawVulcan char]][[CampGay acters]] and FanService. Yet it's a very self-aware parody with some really profound ideas about evolution and humanity's place in the universe, and these become clearer and clearer the longer you watch, as CerebusSyndrome hits. Plus there's quite a few {{Genius Bonus}}es for those science geeks willing to tune in, such as the names of the [[FourIsDeath four Beastman generals]] and [[MeaningfulName Lordgenome himself]].
* In ''Anime/ReadOrDie'' Yomiko aka Agent Paper acts very clumsy, carefree, and childlike even in the heat of battle, but when finishing off her opponents, she lets loose some glimpses of her badass side.
* The main character of ''TheLegendOfTheLegendaryHeroes'', Reiner Lute, is shown as a lazy, failing student in the Roland Magical Academy near the beginning of the anime. [[spoiler: This lazy facade is in fact, merely a method that allows him to hide that he is in fact, the single most skilled Magician in all of Roland and the fact that he possesses the [[MagicalEye Alpha Stigma]], a power that allows him to copy any magic that he sees, and that, when he is put under severe emotional strain, pushes him into a [[SuperpoweredEvilSide Superpowered evil state]] in which he is easily able to slaughter fifty enemy Magic knights without even breaking a sweat]].
* Xerxes Break, in ''PandoraHearts'', may be an example of this. [[spoiler: All the crazy quirks are absent in the flashbacks, and seem to disappear when he gets serious.]]
* Isis of ''[[MagicalGirlLyricalNanoha Magical Record Lyrical Nanoha Force]]'', who initially looked like an ordinary clothes merchant who naively decided to help Tohma and Lily on a whim without fully realizing the level of danger she's putting herself in. [[spoiler:Then we learn that it's just a facade she's using to hide her real identity from [[TheFederation the TSAB]]. While there have yet to be a full reveal on just what she really is, we do know that she is a very powerful and skilled individual, to the point that the Huckebein deemed her as the biggest threat in Tohma's entourage]].
* [[spoiler:Toru Nanamine]] in ''Manga/{{Bakuman}}'' acts like an overly enthusiastic manga newbie and breaks the rules by submitting it online. He apologizes and deletes it, but it all furthers a multi-layered plan to draw attention to himself, enabling him to show his next piece to the editor in chief himself and get some people to give him feedback on his work as part of his plan to get serialized as quickly as possible.
* The title character in [[TheLegendOfSunKnight The Legend of Sun Knight]] is terrible at swordplay. He spends most of his time getting stabbed, spouting inane platitudes about the God of Light, and keeping up with his beauty regimen. [[spoiler: Luckily for him, he's also a naturally talented mage, assassin, and necromancer, who shows signs of being a capable Chessmaster when he's backed into a corner. He was trained to play the part of the angelic ditz because it's good politics and PR]].
* Punie Tanaka of ''DaiMahouTouge'' acts like a ditzy schoolgirl, until it's inconvenient. Then the smile goes, the high-pitched voice goes, and suddenly the ruthless queen-in-training emerges. This is the point when you should run away.
* In Episode 8 of ''Anime/SuperSonico'' we're introduced to Ena, Suzu's younger sister and a self-proclaimed genius detective. She shows up right after Sonico is found unconscious inside the apparently-locked waiting room of Suzu's workplace, where she and her band were due to practice that night, and proceeds to spend the entire episode making up ridiculous theories as to what happened and who the culprit is, until Sonico eventually comes to, everyone agrees it was just an accident, and the group have to head off home without practicing. However, in TheStinger Ena reveals that she'd known the truth from the very beginning ([[spoiler:Miina, having accidentally damaged the amplifier the band were due to use, knocked Sonico out so the damage wouldn't be discovered and she wouldn't get fired]]), and had been deliberately playing dumb in order to waste time until the group had to leave without practicing, thus hiding [[spoiler:Miina's]] crime (Ena's only interested in uncovering the truth, not arresting criminals).
* Lacus Clyne from ''Anime/MobileSuitGundamSeed'' comes off as an especially ditzy version of TheIngenue in her first appearance, and is so seemingly innocent and naive that's it's rather horrifying. In truth she's a GuileHeroine, {{Chessmaster}}, and political manipulator of the highest calibre, and is probably the smartest person in series barring only BigBad [[spoiler: Rau Le Creuset]].
** This comes into full play in the sequel when she organizes her own third party superpower called the Terminal, have them create insanely powerful mobile suits that she gives to her friends, and then uses them to become the core fighting strength of the Three Ships Alliance. She goes on to face series BigBad [[spoiler: Durandal]] in XanatosSpeedChess for the rights to control mankind's future, [[spoiler: and once she wins, she becomes part of the ZAFT supreme council, possibly even the chairwoman, meaning that two twenty year old girls, her and [[LadyofWar Cagalli]] basically control the whole world and its colonies. And if you have any opinions about that, they could easily wipe you out by sending out those insanely powerful mobile suits piloted by their boyfriends[[note]]As a bonus, Kira is also Cagalli's twin brother and Athrun is Lacus's ex-fiance and childhood friend, reducing chances of them betraying the two girls to near zero.[[/note]]. Fortunately, they are the good guys.]]
* ''MedakaBox'': Medaka's older brother Maguro often acts like a perverted sicko who has a bit of an obsession with his sisters. But he's also incredibly intelligent, a master researcher, and well aware of the strengths of his allies.
* In ''TigerAndBunny'', there are hints that Kotetsu exaggerates his klutziness and incompetence as a way making it easier for people to disregard him (and thus keep them from getting too close to him and worrying about him). WordOfGod confirms this.
* The anime version of ''WanderingSon'' implies this with Chizuru, while the same scene in the manga just shows she can be something besides an outlandish {{Cloudcuckoolander}}.
* Kami does this when he possesses a human in ''DragonBall.'' He poses as an incredibly dumb and very lucky fighter during the third tournament storyline, but reveals his true colors while fighting Yamcha.
* Roberta of ''Manga/BlackLagoon'' is definitely this. No one would expect the maid that just burned supper to be [[spoiler: an ex-FARC assassin]].
* ''Eikou no Napoleon-Eroica'' we have the title character, NapoleonBonaparte. His insignificant looks, initial poverty and inexperience with women and politics are genuine, but he uses them to appear much stupider and weaker than he is, only to suddenly show exactly ''why'' he was promoted from captain to ''brigadier general'' after his first real battle. The best example of this is at Austerlitz, where he plays the tzar Alexander I, the Holy Roman Emperor Franz II and all their generals like fiddles by feigning weakness (to be fair, [[IgnoredExpert Kutuzov]] not only saw through the act but actually expected him to pull something like this, but was ignored and overruled multiple times), only to suddenly turn the tables on them and [[CurbStompBattle utterly and completely defeat the Austro-Russian army]].
* In the manga version of ''Manga/SailorMoon'', Minako. She is genuinely TheDitz, but exaggerates this big time to be underestimated (and for fun) and is by far the most battle competent of the Sailor Senshi. The only ones who actually know are Rei (figured it by the final arc, probably after wondering how the hell Minako was able to use her exact exorcism technique in the Exam Battle specials), the Three Lights (who actually call her out on this. Minako immediately dropped the act and threatened to kill them if they didn't drop theirs), and Artemis (who lives with her).
* Commander Pixis in ''Manga/AttackOnTitan'' plays dumb to keep the favors of the upper class. As he leaves an marquis' estate to lead the Battle of Trost, his assistant sharply reminds the nobleman that Pixis is a competent field commander who [[ILetYouWin ''doesn't'' need to throw chess games]] out in the field.
* General Eita Touga of ''Manga/TwelveBeast'' feigns helplessness and prefers complete submission, if it means he doesn't need to fight--he'd rather not get violent, thanks. If it comes to a head, though, he ''will'' kick your ass.
