* ''Series/MarriedWithChildren'''s Al Bundy. On occasion, for whatever reason, Al - schlubby loser Everyman Al - would take it upon himself to beat the living shit out of some poor bastard and he would do so with the psychotic glee you would expect from a man with often literally no other joy. Of all the things Al Bundy failed at - and Al Bundy failed at almost everything he put his hand to - he never once lost a fist fight (or was even mentioned to have lost a fistfight) in the show's entire history.
* ''Series/ICarly'': Gibby. If you are a friend, but betray his trust, or someone who dares kidnaps his friends, he won't think twice about beating the fudge out of you.
** T-Bo, a background character who runs the Goovy Smoothy and is normally seen just putting random items on sticks to sell and being wierd, reveals himself to be one in ''iStill Psycho'' when he helps [[MamaBear Mrs. Benson]] [[BigDamnHeroes rescue the iCarly gang]] from [[AxCrazy Nora]] and her equally insane family. Not only does he kick down the basement door so Carly can rescue Spenser, he singlehandedly takes down Nora's father.
* Played with in Disney's ''[[TheSuiteLifeOfZackAndCody The Suite Life]]'': Apparently London Tipton is quite the athlete (notably in volleyball), but only when she's mad.
* In ''Series/GetSmart'', Maxwell Smart may be a bumbling idiot most of the time, but when he realizes the situation is becoming make-or-break, then he buckles down and becomes nearly unstoppable.
* R.J., TricksterMentor of ''Series/PowerRangersJungleFury'', seems at first to be nothing more than an overly-mellow pizza restauranteur. Then he steps out of the kitchen and reveals himself by taking down a squad of {{Mooks}} without breaking stride, and suddenly the guy who seemed like bumbling comic relief a few seconds ago takes on a whole new light. He barely changes at all, busting out the crazy martial arts skills while remaining as calm and carefree as ever.
* Phineas from ''Series/PowerRangersMysticForce'' is an odd example of this. He's the PluckyComicRelief of the series, but amidst his antics, he often—no, ''always'' gives the good guys a crucial helping hand whenever he appears. The apex is shown when he, Leelee, and Clare infiltrate the villains' lair in the fourth-to-last episode of the series, and he singlehandedly [[CurbStompBattle Curb-Stomps]] a group of [[EliteMooks Styxoids]] that come to stop them.
* Genta from ''Series/SamuraiSentaiShinkenger'', and by extension Antonio from ''Series/PowerRangersSamurai'', fit this to a tee: laid-back, goofy, and the definite PluckyComicRelief characters of their respective shows, but when it comes time to throw down, they unleash the fury.
* River from ''Series/{{Firefly}}'' is a Crouching ''Crazy'' Hidden Badass. Most of the time, she tends to be a {{Cloudcuckoolander}} with some endearingly whimsical moments mixed in with seriously disturbing fits and a few AxCrazy moments. But mess with her brother Simon or her friend Kaylee, and she will take you down, whether by gunning down three men with her eyes closed or orchestrating an impressive BatmanGambit. And that's even before the BigDamnMovie.
* ''Series/BuffyTheVampireSlayer'':
** Drusilla exhibits only [[{{Cloudcuckoolander}} the loosest connection to reality]], and spends most of the time behaving like an idiot child (e.g. cooing over her pet bird, which died because she left it in the cage and forgot to feed it). But when she does fight, she's extremely dangerous, and capable of killing a Slayer with a slash of her fingernail.
** Xander. Whether it was magic tuxedo, skill with a crane, or just a combination of borderline TooDumbToLive and luck, Xander managed to be a useful and functional member of a team that included a slayer, a powerful witch, a werewolf, a vampire, a half-demon, and [[ArsonMurderAndJaywalking a high school librarian.]]
** Whistler seemed like a pretty harmless 'spiritual advisor' type, but come Season Nine and he's showing off sufficient power to leave Nash and Pearl quivering in fear and punching holes through Angel.
** On ''Angel & Faith #6'' Clem actually beheads a bunch of vampires with his tentacled face
* From ''Series/StargateSG1'': [[ColonelBadass Colonel]] Jack O'Neill. Probably more a case of ObfuscatingStupidity, as you couldn't get to officer rank (much less Colonel) without being fairly smart; he's just a very "military" guy and would like to be told that yes, this alien/Ancient technology/doodad '''will''' do what he thinks it will, instead of listening to a lengthy technical explanation about '''why''' it will do what he thinks it will. He acts BookDumb in everything remotely scientific. He never reads Carter's reports, he refuses to listen to Daniel explain some ancient piece of writing or technology, and acts as if nothing matters except ''WesternAnimation/TheSimpsons''. But when some dumb Goa'uld or other bad guy threatens his team or the Earth, he gets '''very''' serious, and reminds you just why ''he's'' leading this team. In the season 5 episode "Rite of Passage", Cassandra observes that Jack is smarter than he pretends to be.
** A single conversation with Ba'al during a [[EnemyMine temporary alliance]] pretty much sums up why he floats between this and ObfuscatingStupidity.
--> '''Ba'al:''' You cannot be serious.
--> '''Jack:''' Oh I can! I just ''choose'' not to.
** He also happens to be an amateur astronomer (a single comment about an accretion disc results in Daniel hitting a figurative brick wall while talking). When he's not using the telescope on his roof to spy on neighbors, that is.
*** He's only an amateur in the sense that he isn't paid for doing astronomy. It turns out he's got a Masters Degree in astronomy and really is that smart. He's also smart enough to know that he doesn't need to know everything his subordinates know, just that they know about whatever situation is at hand.
* Adrian {{Monk}}: Socially inept, obsessive-compulsive and afraid of everything. But he manages to solve the most baffling crimes and he can hold his own in a fight -- he was a cop once, remember. And if you even so much as ''insult'' Trudy, [[BerserkButton he will hand you your ass]]. In the episode where the suspect was a marathon runner, who grabs the key piece of evidence and takes off on foot. Monk proves that he used to be a great runner in school by giving chase (especially in his new sneakers which he got from his idol).
* Otoya Kurenai from ''Series/KamenRiderKiva'', who at first blush seems to be nothing more than a [[SmallNameBigEgo foolishly self-absorbed]] TheCasanova who doesn't have a serious bone in his body. But then he starts pulling BatmanGambit after BatmanGambit, demonstrating an incredible degree of character judgement, and kicking monster butt with an experimental PoweredArmor -- typically stolen from its intended user as part of said BatmanGambit. It's no wonder that near the end of the series, [[spoiler:the Fangire Queen, normally tasked with killing "race traitors" who fall in love with humans, has herself fallen for Otoya and would go on to bear their child, the show's protagonist Wataru.]]
** Kagami Arata from Series/KamenRiderKabuto. He's pretty much GoodIsDumb, esepcially compare to the show's protagonist [[InsufferableGenius Tendo Souji]]. Doesn't stop him from kicking ass, especially after becoming Gatack
* Jackie Burkhart serves TheDitz with a HairTriggerTemper on ''Series/That70sShow''.
** Eric proves to be one of these when he beats up a guy who insults Red during a Packers Bears football game.
* ''Series/{{Battlestar Galactica|Reimagined}}''
** Brendan "Hot Dog" Costanza fits the trope quite well. Most of the time, he's just screwing around and [[AllSTDsAreAIDS too busy having random rashes.]] But in the cockpit, he's more than competent.
** By the end of the series, most characters who weren't introduced as straight-up badasses (and are still alive) have turned out to fit this trope. [[spoiler: Felix Gaeta's leading an armed mutiny, Laura Roslin's raging refusal to surrender when it appears that said mutiny has succeeded, Romo Lampkin's escaping from a marine who had a gun to his head by stabbing the guy's jugular with a pen, and Gaius Baltar going all Rambo on the enemy Cylons during the battle in the Series Finale]].
* Series/{{Merlin}} may be bumbling, clumsy and at times, naive, but I dare you to get on his bad side. He can certainly kick anyone's butt with the use of his powerful and dangerous magic. [[PapaWolf Especially if you hurt his loved ones.]]
* ''NCIS'''s Anthony "Tony" [=DiNozzo=]. He's a ChivalrousPervert and, at times, a ManChild. An example usually comes up OnceAnEpisode. His backstory is that he decided to go into the police force after he, a civilian out for a walk, saved a young boy from a house fire[[spoiler:, and failed to save the boy's younger sister]]. He became the single best officer in the department before becoming Gibbs' right hand.
** Example of the "Crouching Moron" part from Season 2's episode, "Bikini Wax". [=DiNozzo=] and Kate are going to a prison to interrogate the cell mate of their prime suspect. Tony lectures Kate on the way there about how they're supposed to keep their guards up, since prisoners have nothing to lose. A few minutes into the interrogation, Tony notices an Alpha Chi Delta tattoo, and...
** Example of the "Hidden Badass" part...pretty much every time he's involved in an interrogation. Not only is he skilled at making the ones interrogated say more than they should by annoying them, he can make the ones interrogating him say more than they should. Prime example from "Aliyah": Eli David, head of Mossad, accidentally says too much to Tony while he's being interrogated...and while Vance, Gibbs, and Ziva are watching.
* The 1991 series ''StepByStep'' had Sasha Mitchell's Cody Lambert as the beach bum slacker nephew of Patrick Duffy's Frank Lambert. Though normally a clueless "Valley Dude," in one episode when braced by a group of bikers in a bar, Cody showed why he's played by the man who made two "Kickboxer" films. After clearing the bar of bikers, he reverted to goofy flake with the following dialog;
-->'''Carol''': Cody, I didn't know you knew karate!
-->'''Cody''': Cha, me neither! I'm gonna have to go back and re-read some of my old diaries!
* Jason Stackhouse spends most of ''TrueBlood'' constantly doing absolutely stupid shit, because he's dumb as a stump, and is often led about by just about anyone. Threaten his sister Sookie, however, and he will not just step up; he'll absolutely take you down and make the audience's jaws drop. But he's still dumb as a stump for the most part.
** This appears to be somehow related to Sookie being around. When she disappears for months, she returns to find him a full-fledged cop, having become much more responsible in the meantime and even running the police station, more or less, when the sheriff turns out to be a drug addict.
* ''Series/DoctorWho'':
** The Second Doctor was probably the most representative of this trope. While all incarnations of the Doctor are capable of deadly seriousness and incredible skill, and most (Exception for the Fifth Doctor, the human and hesitant Doctor who would weigh out his choices to see if they were right and often get frazzled while doing so) were usually goofy, Creator/PatrickTroughton brings the apparent goofiness up to eleven. The vast majority of the time, the second Doctor pretended to be a bumbling idiot, constantly stressed out and panicking. However, when faced with the right danger, he drops the act and becomes dead serious and sometimes even diabolic. Or [[ObfuscatingStupidity feigns the act of stupidity altogether to trick his enemies]]. This is especially pronounced whenever he encounters Daleks or Cybermen.
** Professor Chronotis had been a genius, but due to being 2000 years and 12 regenerations old, his mind is starting to go, with things like the names of objects and [[TimeTravelTenseTrouble tenses]] constantly slipping his mind. In lucid moments, he is clearly of significantly above average intelligence even for Time Lords, but these moments are few and far between and hampered by the fact that he just doesn't care about anything other than 'reading books and making tea'. However, he also happens to possess extremely powerful psychic abilities and an ancient TARDIS that he stole.
** The scatterbrained [[{{Keet}} Eighth Doctor]] was an odd duck who gushed over things as simple as shoes, got unbelievably distracted, turned into a chatterbox if you mentioned something that perused his interests, and oftentimes waxed on like a lemony romantic. However, he was one of the most emphatic Doctors and could be deeply affected with either love or hate. The love side would be fun, compassionate, joyful and clever, knowing how to cure others of the rain clouds floating atop their heads. On the hate side of the coin, he suffered [[BreakTheCutie a terrible amount of breaking]] and the end result a hardcore man who could seethe with white-knuckle rage, turn genuinely vicious if you pissed him off, or even tease borderline psychosis when something traumatized him badly enough.
** The Ninth Doctor displayed shades of this. He had an imposing figure, could easily take control of a conflict, and be well beyond menacing if a situation called for it- or a BerserkButton got pushed. However, Nine could also be incredibly goofy and a bit inept on a slow day, such as screwing up landing the TARDIS 12 hours into the future and instead landing 12 months, by which time his companion's mother feared she had gone missing. And instead of calmly explaining the situation or trying to go back in time and reverse this, he let things play by ear, minced his words in front of a hysterical parent, and got slapped for it.
** Rose Tyler could qualify. She certainly has her fair share of ditzy moments; she has to get saved a lot, and sometimes, if she's feeling particularly helpful, she's shouting ineffectually at the villains. [[spoiler: She does, however, absorb the power of time and become a demi-goddess at the end of series 1, sacrifices herself for the universe at the end of series 2, and blows things up like all-get-out at the end of series 4.]]
** The Tenth Doctor. Say you're an alien invader. You capture this odd fellow in a suit and hi-tops; he appears to be batshit insane, jabbering on, often in rather inane ways. And just after he finishes talking, you realize he has just taken down your entire armada.
*** Case in point: the Family of Blood. [[spoiler:The Doctor (using his human disguise/alias John Smith) stumbles into the Family's ship, trying to stop them from destroying the academy where he hid from them. While negotiating with them, the Doctor stumbles about pressing random buttons on the ship before turning over his fob watch (which holds his Time Lord powers). The Family tries to absorb said powers, but they are not there. The Doctor then drops the bumbling human act and reveals he's back to normal. And has just set their ship's reactor to overload. The kicker is that after the ship blows up, the Family realizes that the Doctor hid from them because of ''what he would do to them as punishment'', not out of fear for the Family itself.]]
** Mickey Smith was the "[[ButtMonkey tin dog]]" by his own admission. Series 1 Mickey was a bumbling numbskull who the Doctor absolutely ''loved'' to bill "Mickey the Idiot". He did save the world with a big yellow truck, but later freaked out at a bunch of packaged lab rats prepped for dissection. Mid-Series 2, he decides to [[TookALevelInBadass shape up into a badass]] and "Mickey the Idiot" becomes Mickey the defender of the Earth with a {{BFG}}.
** Brilliant but baffled Professor Yana in the three-part 2007 series finale. [[spoiler: He does a dramatic FaceHeelTurn as he remembers what a badass he is as The Master.]]
** Partially the case for the Eleventh Doctor. He exhibits a ''really'' alien personality, makes wild gestures, is prone to be gawky, often trips over his own sentences, and has a generally uncoordinated air about him. This childishness is implied to be an act that falls when he either trusts someone enough or someone triggers his fury. Then, he can be dark, serious, brooding, severe, liable to send you to oblivion if you anger him in just the wrong way, raise an entire army to tear you down, punish you with a humiliating consequence, and hold his own on a planet against '''''all''''' his greatest enemies for 900 years.
** Inverted by the no-nonsense War Doctor, who has a mostly serious and driven personality focused on the issues at hand rather than avoiding them out of guilt. But, if he has the chance to relax from battle, he gets a tad eccentric, confused, sarcastic, grumpy, and grandpa-like.
** Companion Rory Pond is clumsy, awkward, initially useless in a fight, has a serious inferiority complex concerning the fact that his wife to be seems to love her imaginary friend more than him, and generally is mostly only on board the TARDIS for her. But he will ''not'' take crap if someone is in trouble and by the end of the series has become a major mythical figure and badass fighter. Even after the timelines are reset he remembers living for 2000 years guarding his wife inside Pandora's box, and is an extremely competent fighter, able to face down an army of Cybermen if necessary. [[spoiler:River had to get those genes from somewhere, I suppose...]]
--->'''Amy Pond:''' (to her infant daughter, Melody, as both are being held prisoner by The Silence) "I wish I could tell you that you'll be loved. That you'll be safe and cared for and protected. But this isn't the time for lies. What you are going to be, Melody, is very very brave. But not as brave as they [The Silence] all have to be. Because there's somebody coming. I don't know where he is, or what he's doing, but trust me. He's on his way. He's the last of his kind. He looks young but he's lived for hundreds and hundreds of years. And wherever they take you, Melody, however scared you are, I promise you, you will never be alone. Because '''''this man is your father'''''. He has a name, but the people of our world know him better... as the last Centurion."
** Strax. The series goes out of its way to emphasize how useless he is, unable to adapt to any situation where the answer is not simply killing an enemy. Whenever the [[ViolenceReallyIsTheAnswer situation really does require killing an enemy]] however, he is the last person you want to go up against.
* Vir from ''Series/BabylonFive'' is introduced as a timid and shy comic relief, used to being pushed around by his boss Londo. However as the show goes on he gradually shows more and more backbone, first by not backing from a huge monster (a hologram, but he didn't know that) when sent to deliver a message to technomages, then by telling off an emissary of {{Eldritch Abomination}}s in the most awesome way, and finally by retorting to an insult and a spying attempt by borrowing his Londo's duel sword and trashing the offender's stall and forcing him to confess at swordpoint.
** There's also the time when he invented Abrahamo Lincolni and created an underground railroad to transport Narns to safety. This while his government was fighting an extermination war against the Narns. Considering how insane the emperor was it's likely that Vir would have been killed if anyone had found out about it.
* [[AshesToAshes WPC Shaz Granger]] is hardly a moron, she's just sweet and isn't as badass as the rest of CID. It's kind of hard when you're a plonk in your mid-twenties, trying to live up to the examples of Gene Hunt and Alex Drake. Even Ray and Chris are pretty badass, holding their own in gunfights and having multiple BigDamnHeroes moments - Shaz doesn't even ''carry'' a gun. And then 2.08 hits, where [[spoiler: a bent copper is holding Chris hostage, about to shoot him. A gunshot sounds, and it's Shaz, holding a smoking gun and wearing her wedding dress. To cap it all off, she quips "How you doing, baby?" to Chris.]]
* Vince Teague, the mild mannered small town newspaper editor in ''Series/{{Haven}}''. When a menacing and muscular ex-con shows up in town and threatens Vince's little brother, you can see the until then goofy exterior slough off and his inner badass reveal itself. A couple seasons later it is revealed that Vince is [[spoiler: the leader of the Guard, a badass organization of Troubled people who have protected other Troubled from persecution since Haven was founded]].
* The live action TV version of [[CuteyHoneyTHELIVE Cutie Honey]] had Honey as a ditzy high school student who could take on entire swarms of mooks.
* Agent Bill Hoyt of ''Series/{{Undercovers}}''. He's usually the [[HollywoodNerd nerdy]], [[PluckyComicRelief sycophantic]] tech guy for the Blooms; but in the episode "Xerxes" he [[spoiler:single-handedly takes down the villainess after learning that she had almost manipulated him into falling in love with her.]]
* ''BoardwalkEmpire'' has Eddie Kessler, Nucky's bumbling assistant who often messes up and is often treated as a ButtMonkey. When an assassin comes after Nucky, he [[spoiler:makes the assassin miss his shot, takes the assassin's gun away and then coldly shoots the guy in the back as he is trying to run away]]
** While few people would consider Nucky to be a moron, he is a politician and talks like one so some opponents assume that he is just talk and can be easily pushed around. When three goons come after him in his own office, he dispatches all three of them by himself and then wages a bloody and ruthless MobWar against their boss.
** Richard Harrow is a disfigured ShellShockedVeteran who has trouble talking due to his injuries and at first glance people might assume that he is brain damaged. However, he is probably the deadliest individual on the show and becomes a OneManArmy when needed.
* This is pretty much Castiel from ''Series/{{Supernatural}}''. Perpetual confused look, especially when it comes to humans but piss him off and he can kick your ass to hell and back.
** Also [[spoiler: Gabriel]] in a sense. This is an [[spoiler: archangel]] who is pissing around messing with humanity.
** To quote Dean: "Word to the wise: don't piss off the nerd angels."
* ''Series/CriminalMinds'' has a few of these. It's to be expected from members of the team-they are FBI agents after all-but a lot of the Unsubs and quite a few would-be victims fall into this category. One example that springs to mind is the strung-out prostitute from "Legacy" who looks to be a disposable victim when the [=UnSub=] picks her up but manages to make her way through the killer's torture factory-including walking barefoot through a roomful of broken glass-and survives to see him taken down at the end of the episode.
* ''Series/{{Scrubs}}'':
** Todd "The Todd" Quinlan is an utter meathead, seemingly only capable of communicating through innuendo and ThatsWhatSheSaid jokes. But he is also a ridiculously talented surgeon, one of the best in the hospital.
** Elliot is a pretty stereotypical spoiled rich girl, but she's still a surprisingly competent and dirty fighter.
--->'''Carla:''' How did you learn to fight like that?\\
'''Elliot:''' Well, when you grow up on an orchard, you don't have much choice...\\
''[Carla stares]''\\
'''Elliot:''' Apple thieves.\\
'''Carla:''' Ah...
* ''Series/{{Highlander}}'''s Methos poses as a mild-mannered, sheltered scholar with the Watchers; even with his friends who know he's the oldest living Immortal, he'd rather lounge around drinking beer than accept a challenge. And he would just as soon not talk about how he [[spoiler: [[RetiredBadass used to be]] [[RetiredMonster Death of the Four Horsemen]]]].
--> '''Methos:''' Just because I don't like to fight, doesn't mean that I ''can't''.
* Series/SledgeHammer; his {{catchphrase}}, "Trust me, I know what I'm doing." is a {{blatant lie|s}}, but when the chips are down, his {{crazy awesome}}ness kicks in.
* In social game shows like ''Series/{{Survivor}}'' and the American ''BigBrother'', a good (albeit boring) strat is to make everyone think you're not a threat to them, so they won't target you for eliminations. Then, you start playing much harder and make them regret not taking you out in hindsight.
** Perhaps the most triumphant example in ''Series/{{Survivor}}'' was Fabio. His entire strategy was basically him flanderizing his [[DumbBlonde himbo]] personality and flying under the radar while the alliances pick off at people perceived to be bigger targets. Then when he was the only target in between the [[TheLoad easily beaten Dan]], he finally started to win immunity, and then [[CrowningMomentOfAwesome tricked Chase and Sash into telling Jane they were voting her out TO HER FACE!]] He then chain-won immunity all the way into the final three, making Chase and Sash both think "OhCrap".
** Attempted but failed with Brett and Ashley. Both Brett and Ashley just kept their mouths shut and hid behind numbers so they wouldn't be targeted. Then all of a sudden, they start competing well in challenges and force the dominant alliance to vote each other out first. Immediately the person in charge of the game thinks OhCrap because this person they perceived to be a nothing is actually not bad at the game. Unfortunately; Brett & Ashley both failed to win the final immunity and were therefore the final member of the jury.
** The first time Cirie Fields played Survivor, she was almost voted out very early in the game twice due to her lack of physical ability and general aversion to the great outdoors. However, Her motherly attitude and unassuming demeanor not only made her some powerful (and attention-deflecting) friends, but also hid a very shrewd strategist, and she managed to make it all the way to the final 4 with some truly brilliant gameplay, including [[https://www.youtube.com/watch?v=npog1sGZL9Q One of the greatest power plays in Survivor history]]. Not bad for the self-declared couch potato.
** Before either of those three, we had Lillian Morris. She was very emotional and would cry at the drop of a hat...and became Fairplay's personal ButtMonkey. After a bit of FridgeBrilliance where he avoided elimination at the final four and had to face two people who weren't good competitors, Lil ''immediately'' takes to the final immunity challenge and doesn't move a ''muscle'', while Fairplay starts trying to cut a deal, only for Lil to constantly shoot him down and taunt him to break down his spirit.
* Hiro of ''Series/{{Heroes}}'' is a WrongGenreSavvy {{Otaku}} who spends most of each season suffering from severe PlotInducedStupidity. But when he gets his act together and wades into the fight, he will ''own'' you. He has basically singlehandedly defeated [[ArchEnemy Sylar]] (a couple of times), two seasonal {{Big Bad}}s, and an entire government black ops ''agency''. The only villain on the show who was ever any match for him was Arthur Petrelli, who had his same power ([[AllYourPowersCombined among many others]]).
* Walter Sherman of ''Series/TheFinder'' seems a harmless, goofy man who's just two steps short of an institution. It's not until he's strung out from a bad Find and faced with three bad guys that we're reminded he was an Iraq veteran. He does so by killing two of them with their own guns before snapping the last one's neck.
* ''MysteryScienceTheater3000'' has Gypsy, who at one point beats down her creator Joel after he was being mean to the other robots by cheating at 'Rock, Paper, Scissors', and Professor Bobo in the episode TheGiantSpiderInvasion , in which he defeats a race of pod people assimilating the Mads ''and'' the SoL crew.
* RuPaulsDragRace has Shangela, who didn't even survive the first week of Season 2, come back Season 3 as an opening plot twist... and proceed to last through over half the season (notably winning a [[http://www.logotv.com/video/misc/627979/stand-up-challenge-shangela.jhtml?id=1659110 comedy-routine based challenge]] in the process!)
* Bob Sweeney from ''{{Justified}}'' is an overweight, unpromotable constable whose cockiness has found him on the wrong side of a gun a couple of times. Push one of his beserk buttons or test his loyalty to Raylan, however, and you unleash a whole different beast. To date, he has taken down two attackers on separate occasions with a concealed knife, withstood a vicious beating and opened fire on a couple of guys with an AK-47 because they made fun of him.
-->'''Raylan Givens''': People underestimate Bob at their peril.
* Chang of ''{{Community}}'' is a CloudCuckooLander whose general plot role is just to be annoying. However, over the course of Season 3, [[spoiler:he becomes completely insane, eventually [[FromNobodyToNightmare taking over the school]] and installing himself as a Stalinesque dictator and nearly killing the entire student body.]]
* [[ExtravertedNerd Steve Urkel]] of ''Series/FamilyMatters'' fame is this trope [[PlayedForLaughs played entirely for laughs]]. He's just ''so'' incompetent, inept, and prone to disaster that [[EpicFail the amount of destruction he causes occasionally borders on the epic]] -- never more so than in a nightmare sequence of Laura Winslow's. In the dream, Steve builds a fully-fuctioning nuclear weapon and inadvertently detonates it by uttering the code word "buttercup", blowing half of Chicago completely off the map and killing millions. As always, all Steve can say in light of his actions is [[CatchPhrase "Did I do that?"]]
* Penhale from ''Series/DocMartin'', heavier on the moron than the badass admittedly, but he came across as a very professional and scary copper when he dealt with the evil loan sharks threatening Bert. And when his estranged wife shows up apparently unaware that they've been divorced for four years, he's clearly still desperately in love with her, but the first thing he does is ask her the date, confirming that she's not well.
* Diotoir from ''Series/RobotWars''. An obvious joke entry featuring a rather ineffective weapon and covered in highly flammable red polka dot fur. However, it's predecessor Nemesis defeated a house robot, and Diotoir itself reached 2 Heat finals, the semis of the First World Championship and was one of the few robots to hand [[TheAce Tornado]] a defeat. Beware the beast in red dotted fur.
* Brutus on ''{{Rome}}''. Doesn't seem to understand or care much for politics at the start and comes off as a bit of a ditz, yet when push comes to shove he can not only stick a knife in you but lead an army to battle.
** Titus Pullo at the start of the series. In a show swarming with badasses he manages to be the second most badass of them all (only outdone by Vorenus) but he can be rather dense at times, tends to not think things through and has some utter ditz moments (see the quote below). As the series progresses though he becomes less and less the moron part, due to his CharacterDevelopment.
-->'''[[spoiler:Cicero]]''': I daresay, your work today will earn you immortality.
-->'''Pullo''': (''very pleased'') How's that?
-->'''[[spoiler:Cicero]]''': I will be in all the history books. My killer's name no doubt will live on also.
-->'''Pullo''': Ah. My name. (''laughs awkwardly'') I thought you meant me.
