->'''Mr. Croup:''' You find us funny, Monsieur le Marquis, do you not? A source of amusement. Is that not so? With our pretty clothes, and our convoluted circumlocutions-\\
'''Mr. Vandemar:''' ''(murmuring)'' I haven't got a circumlo...\\
'''Mr. Croup:''' -and our little silliness of manner and behavior. And perhaps we are funny. [...] But you must never imagine, that just because something is funny, Monsieur le Marquis, ''it is not dangerous''.
-->-- ''Literature/{{Neverwhere}}''

So you've got a person who might fulfill the role of [[PluckyComicRelief comedic relief]]. For the most part, both the fans and the characters in-story see them as just a great big doofus. Possibly, they spend more time [[ItAmusedMe acting ridiculous]] or laughing in the face of SeriousBusiness than [[LetsGetDangerous getting dangerous]]. Sure, they might rant up and down about how they're going to conquer the world in the name of Evil with a capital E or [[TalkingTheMonsterToDeath drive the villains to suicide through bad jokes]], but in the end they seem to pose little threat to all present.

[[FridgeLogic There's just one thing most people forget:]] acting silly does not mean you aren't a OneManArmy. The villain can be ''really'' dangerous despite being LaughablyEvil; in fact, their silly nature may even ''add'' to their evil because of the unexpectedness of it. It could be a [[ObfuscatingStupidity façade]]. It could be that they just do it for the [[RuleOfFunny lulz]]. Or maybe they are so badass that they find even the most dangerous scenario to be either just a joke or just a daily, normal thing. A well-hidden BerserkButton can be pressed. In any case, beware the silly ones.

Often achieved by way of CrouchingMoronHiddenBadass. Can be a variation of UnderestimatingBadassery. Compare HarmlessVillain and NotSoHarmlessVillain. Also compare FightingClown. Contrast MilesGloriosus. May overlap with {{Cloudcuckoolander}}, at least by appearances. If it's this same silliness that makes them dangerous, it may overlap with CrazyAwesome. May make you liable to ThreatBackfire. See also BewareTheNiceOnes if they're kind and caring and BewareTheQuietOnes if they're known for their near silence.



[[folder:Anime & Manga]]
* Pictured above is Gluttony from ''Manga/FullmetalAlchemist''. Of all of the [[QuirkyMinibossSquad homunculi]], he's the only one who's played for laughs, since he's [[FatIdiot fat, dumb]], and overall acts like a lovable dope. There's also the fact that he's very innocent, and only does what he does because his higher-ups tell him to, and he genuinely doesn't see any wrong in what he's doing. However, as his name suggests, [[ImAHumanitarian he has a bit of a hunger streak]]. In the manga and ''Brotherhood'', it's not helped when he's reminded of [[spoiler:Lust's death by Roy Mustang's hands]], [[BerserkButton which drives him into the monstrous state also shown above]].
** In the [[Anime/FullmetalAlchemist original 2003 series]], he becomes this after [[spoiler:Dante steals his rational thought, leaving only his infinite hunger in its place]].
* Matsuda Touta from ''Manga/DeathNote''. When Matsuda [[spoiler:realizes that Light is actually Kira, [[BreakTheCutie he breaks emotionally]] and shoots Light's hand when he tries to use a piece of the Death Note. When Light tries again, Matsuda (who was once or twice hinted to be a decent marksman despite his silliness) flies into a furious UnstoppableRage and then turns Light into swiss cheese with a barrage of bullets, only prevented from delivering the CoupDeGrace by the other officers]].
-->'''Matsuda:''' [[spoiler:"I'll kill him! I'LL KILL HIM! '''HE HAS TO DIE!'''"]]
* Etemon in ''Anime/DigimonAdventure''. Yes, he's a wannabe rock star comedy monkey, but that never stopped him from {{curbstomp|Battle}}ing the protagonists every time they saw him. The fact that he's a [[EvolutionPowerup level higher]] than them ''and'' can negate their ability to powerup helps tremendously. He also managed to throw their leader, Taichi, back to the real world, [[WeWereYourTeam resulting in the break up of the team left behind in the Digital World]]. He did it by ''[[TakingYouWithMe dying]]'', mind you, but that was a lot better than his predecessor Devimon did. He comes back and kicks off the series's RunningGag of killing Leomon at least once a series.
** Pinocchimon and Piemon are silly, fun-loving, Mega level sociopaths. The latter gets bonus points for also being a MonsterClown.
%%* Many a MonsterOfTheWeek from ''Manga/InuYasha''.
* Another Franchise/{{Digimon}} entry would be the protagonists of [[Manga/DigimonVTamer01 the V Tamer manga]] Taichi and [[MyHeroZero Zero]][[DepartmentOfRedundancyDepartment maru]]. They call themselves the "[[{{Pun}} 100%]] [[MeaningfulRename Combination]]" as up to the story start, they haven't lost a match with paired together. That record holds throughout most of the series, even against mon of a [[PowerLevels higher level]]. They are also prone to Victory Dances, and other bouts of light-hearted messing about, not even five seconds after they've won.
* Prince Clovis from ''Anime/CodeGeass'' is depicted as a buffoon and is loved by his siblings, but [[MoralEventHorizon he ordered his men to indiscriminately slaughter everyone they came across]] [[MakeItLookLikeAnAccident in order to cover up his mistakes]]. One wonders what other atrocities he might have gone on to casually commit [[spoiler: had Lelouch not shot him after interrogating him]]. The fact he had also captured an immortal and was experimenting on her suggests even more skill then initially seen.
* Maximillion Pegasus from ''Anime/YuGiOh'' is more or less this trope. Most of his dialogue is that of mockery and he acts like a playful child. But underneath that is a cold, calculating villain who through ultra-powerful cards and mind reading can prove to be a dangerous opponent. And when you start beating him, he drops the goofiness and becomes dead serious. This attitude is best represented through his Toon Monsters: Very silly looking creatures, but with enormous power that is difficult to beat. When they are destroyed, Pegasus becomes much darker...
** The toon monsters themselves embody this trope, as do toons in general, as described in other sections.
* In ''Manga/BlackButler'', we have Lau. You know, the goofy guy who constantly barges into the Phantomhive mansion and irritates the crud out of Ciel? [[spoiler: [[ObfuscatingStupidity it was all an act.]] Oh, and he was the head of the Chinese mafia.]]
** Also Madame Red. The red-dressed, haired and eyed aunt of Ciel who sees him as her surrogate son? [[spoiler:She's half of Jack the Ripper, punishing prostitutes for requesting abortions while she can't have kids because of an accident that also killed her husband; the other half being her seemingly-stupid but highly sociopathic shinigami butler Grell Sutcliff.]]
*** [[spoiler: Grell still fits this trope when in his true shinigami form. Throughout the show, he spends a lot of time being [[ThePratfall essentially]] [[ButtMonkey a]] [[AbhorrentAdmirer walking]] [[QueerPeopleAreFunny punchline]]. It's very easy to forget that he's capable of killing people in cold blood, and that he's a strong enough fighter to hold out against Sebastian for several minutes (most people manage about two seconds).]]
** The three bungling servants at the Phantomhive mansion. While they seemingly behave incompetently, the truth of the matter is [[spoiler:Sebastian hired them as bodyguards to protect the mansion. Bard's a former soldier, Mey-Rin's an ex-professional assassin, and Finny has superhuman strength. The three managed to effectively force a gang of mobsters to retreat in their failed attempt to attack the mansion]].
*** Well, they don't so much "force a gang of mobsters to retreat in their failed attempt to attack the mansion" as "brutally murder a group of seven highly trained assassins who were going in to kill them all." The most used sound effect in that chapter was Splat.
** The Undertaker. He's a ridiculous {{Cloudcuckoolander}} who demands payment in jokes. [[spoiler: He's also a highly trained shinigami, and as such can be extremely dangerous when he wants to be. Basically, Manga/BlackButler has an entire army of comic relief characters, and all of them are capable of doing very unpleasant things to you.]]
* Mr. Percival Pompous, as he's called in the 1960's version of ''Anime/AstroBoy'', seems a ninny comic relief from his whiny voice and habit of falling on his face; when action is needed, though, he's a tough fighter and a crack shot. Plus a reasonably good detective.
* In ''LightNovel/TrinityBlood'', we get a rare heroic example. Abel Nightroad is portrayed as a complete and utter moron throughout the entirety of the series. But beware! Threatening [=ANYone=] he cares about is [[BerserkButton a really bad idea]]. [[spoiler:"Nanomachine Crusnik 02, output 40% approved." <<< This phrase activates an utterly terrifying demon monster that [[FoodChainOfEvil eats vampires]]. [[CrouchingMoronHiddenBadass Moron, indeed]]]] BEWARE!
** And just before the manga [[CutShort ended]] [[AuthorExistenceFailure abruptly]], female lead Esther meets a goofy, scatterbrained, lost-without-his-butler English gentleman [[spoiler: [[NamesToRunAwayFromReallyFast named]] [[CainAndAbel Cain]]]].
* ''Manga/OnePiece'' lives and breathes this trope. Many a villain is introduced as an apparently {{harmless|Villain}} [[{{Cloudcuckoolander}} weirdo]] who does things such as accidentally hypnotizing himself more than once, humorously disagreeing with the protagonist about the taste of a pie or just plain looking and/or talking funny. A few chapters later they turn out to be [[LetsGetDangerous truly dangerous]], usually without losing any of their silliness.
** For that matter, some of the Straw Hats can qualify as this. TheCaptain Luffy may appear like a clueless idiot who only likes to eat meat but should [[BewareTheNiceOnes you]] [[BerserkButton cross]] [[PapaWolf him]], it won't be pleasant. Likewise with CowardlyLion Usopp.
*** By the end of the TimeSkip, the ''entire crew'' count as this. They might be one of the most eccentric pirate crews in the world-but they're also one of the most powerful and legendary ones as well.
* Right, so, in ''Manga/{{Naruto}}'', there's this [[StandardEvilOrganizationSquad group of bad guys]]. After one bites it, this minion of the ManEatingPlant guy gets promoted to full [[QuirkyMinibossSquad miniboss-status]]. He seems kinda lame, but as it turns out, [[spoiler:he's not only the organization's founder and secret leader, he's explicitly carrying out the EvilPlan of one of history's most powerful ninjas]].
** And now, he's become the [[spoiler: Ten Tails' host.]] Remember, the last man who did that was the Sage of Six Paths, a man who could have killed Hashirama , The "God of Shinobi" with about as much effort and in as much time as it would have taked to look at him. He also created all ninjutsu and the Tailed Besats. By himself.
** His partner [[MadBomber Deidara]] was a candidate as well. Sure, his banter about art and his violent temper are funny, but he was able to take out [[SealedEvilInACan Gaara]] and didn't do so bad against Sasuke either.
*** Speaking of Gaara, his demon Shukaku certainly qualifies. While he is amusing to watch and acts like a violent drunk, he is still very dangerous and was more than a match for the boss toad Gamabunta.
** Might Guy as well. While the guy ''is'' a legitimate goofball, Itachi (the man who almost single-highhandedly wiped out one of Konoha's strongest clans) still considered him as a legitimate threat. In fact, he's one of the few characters capable of taking out a member of Akatsuki by ''himself''.
** Hell, a lot of the cast would fit this trope in some way. You've got Jiraiya, a hopeless pervert and LargeHam who is also so good at what he does [[spoiler: that [[AGodAmI Pain]] has to hide half of his bodies just to defeat him]]. Guy's [[GenerationXerox student]], Rock Lee delivers [[TheAce Sasuke]] his first real beatdown of the series[[spoiler:, kicks [[BigBad Madara]] so hard he ''splits in half'']] and usually has to be a victim of TheWorfEffect to be defeated. Even Naruto counts, being a notorious prankster and hyperactive idiot, as well as a serious heavy hitter. [[spoiler: He gets his silliness from his mother, Kushina, who survived being ImpaledWithExtremePrejudice an hour after giving birth to him and managed to restrain the Kyuubi with chakra chains just to protect her child.]]
* ''Anime/DragonBallZ''
** The Ginyu Force, five goofy {{manchild}}ren whose poses are SeriousBusiness as they play rock-paper-scissors to decide who fights who and bet candies on who wins. Their power levels and/or their physical and special abilities are no laughing matter. Guldo alone would have killed Krillin and Gohan had Vegeta not stepped in. The 3 together were absolutely no match for any one of the other four.
** Also the last villain of the series, Majin Buu -- a fat, childish, bubblegum-pink creature, which nevertheless was rightfully seen as the most dangerous entity in the universe.
** Goku, especially when he was a kid. Because of how naive and childish he was he had no problem playing hide-and-seek with his enemies, choosing to eat over fight, or just act like a goofball in the middle of a battle. Despite this, he still kicked his opponent's butts and not let's get started on what happens when he is serious. This is {{downplayed|Trope}} when he is an adult since most of his silly moments happens outside the battlefield. [[LetsGetDangerous When he fights, he usually drops all the silliness]].
** [[LovableCoward Yajirobe]] is usually a comic relief character in ''Anime/DragonballZ''; he's a slob who spends most of his time eating, and has NoSocialSkills. However, he was able to turn the battle between Goku and Vegeta around by ambushing Vegeta (who had assumed giant ape form) and slicing his tail off, forcing him to assume humanoid form again and letting Goku regain the advantage.
** From the canon movies and ''Anime/DragonBallSuper'' we have Beerus, a PhysicalGod who naps for decades at a time, obsess with food, and have a butler with him at all times to keep him out of trouble. He is also the most powerful being in the universe, [[spoiler: save for Whis]], and curb stomps everyone he has ever fought, including [[spoiler: Super Saiyan God Goku]].
** The original series had Shen, a normal guy who managed to get to the final 8 of the Tenkaichi Tournament bysheer dumb luck, since he always managed to trip or curl up in a way that succeeded on knocking out or throwing off the ring anyone who fought with him by mere mistake... or so he wants you to believe. [[spoiler: In the fight against Yamcha he drops the silly act and reveals he's actually Kami, the god of Earth, borrowing a human body to enter the tournament undetected and fight against Piccolo. The name Shen was a clue, as it's half of Shen-Long's name.]]
* ''Anime/{{Pokemon}}'''s Team Rocket would actually succeed in many of their schemes if the twerps didn't get involved. In ''Best Wishes'', the silliness is completely dropped for Jessie and James, and at a minimum for Meowth. ''XY'' returns them all to clownish villains, but retains shades of their previously found deadliness, making this trope ever prominent.
** The Pokemon Poacher brothers from the Larvitar storyline in late-Johto were portrayed this way, while Butch and Cassiday got {{flanderiz|ation}}ed into this.
** There are also just gobs of individual Pokemon in the show that were depicted this way. Some of the best examples include Wobbuffet and the Bellsprout Ash almost lost to in the Indigo League. Wobbuffet became almost entirely a joke character later on, but had a sudden moment of badassery in the first episode of XY.
* ''Manga/{{Bleach}}'': Mashiro Kuna is a former shinigami who is 100+ years old, looks to be somewhere in her 20s, and acts like an eight-year-old. Her appearances highlight her as a joke character who has tantrums in the middle of murder investigations because her partner won't pay attention to her protests that she's hungry. She fights by kicking things to death and occasionally fires off lasers with an area of 20+ yards.
** Giselle Gewelle from [[spoiler: the Vandenreich]] as well. She is a cheerful young woman who likes to make silly faces and snark at her friends. She's also a [[CombatPragmatist ruthless fighter]] who is remorseless when using her BloodMagic powers to force a bunch of soldiers to [[PsychicAssistedSuicide kill themselves]].
** The [[spoiler: Royal Guard]] also qualify for this trope: the five main members are all very flamboyant and seem to enjoy confusing people or acting as a BunnyEarsLawyer. With that said, they are also all [[spoiler: former captains promoted to protect the Spirit King, and the five alone are apparently more powerful than the [[OneManArmy entirety of the Gotei 13 put together]]]].
* ''Manga/RurouniKenshin'' has Kenshin, who is usually a polite, obvious moron ... and, if you push him too far, the legendary assassin Hitokiri Battousai.
* The main character of ''Sasuga no Sarutobi'' is a perverted, meatball-shaped, troublemaker who jokes about everything. He's also near-invincible in battle.
* Apachai and Kensei of ''Manga/KenichiTheMightiestDisciple'', the former a ManChild while the latter is a DirtyOldMan, but both are masters.
* [[TheGrimReaper Lord Death]] of ''Manga/SoulEater''. The goofy face, goofy voice, and general jokester personality can make you forget he's the guy who handed the Kishin his ass [[spoiler:in a bag made of his own skin]] all those years ago. And be warned, Lord Death is by no means rusty.
* Vash the Stampede from ''Manga/{{Trigun}}''. He acts cowardly and stupid, providing general comic relief through out the show, but is in fact incredibly dangerous. If you piss him off (by hurting... pretty much any living thing) he can -- and ''will'' -- execute six precision quickdraw shots on your body, any one of which could cripple you. Why six, you ask? [[OhCrap Because his revolver only has six chambers]].
* This often happens to be the case with characters from ''Manga/FairyTail''. If a character looks or acts in a manner that seems strange, don't be surprised if turns out that they can kick 20 flavours of ass.
* Fay D. Fluorite from ''Manga/TsubasaReservoirChronicle'' is a big source of comic relief, but [[LetsGetDangerous when push comes to shove]], you don't want to be pitted against an [[spoiler:insanely powerful, well-trained mage]] who knows hand-to-hand combat and is skilled with both a normal bow and a crossbow. Not to mention that he [[spoiler: [[EmergencyTransformation gets turned into a Vampire]] half way through the series, complete with WolverineClaws which he makes good use of as [[BigBad Fei Wang Reed]]'s {{Mooks}} learn the hard way]].
* The Millenium Earl in ''Manga/DGrayMan'' looks like an obese grinning goblin with an umbrella that makes him fly like Marry Poppins and often ends his speech bubbles with a heart. Despite this, though, do remember that he's the GodOfEvil.
* ''Manga/PandoraHearts'': Xerxes Break, the clownish servant of the Rainsworth family that constantly eats candy and carries around a doll on his shoulder. [[spoiler: He was once The Red-Eyed Ghost, an infamous Illegal Contractor that murdered over a hundred people being pulled into the Abyss.]] He's also a MasterSwordsman and has a contract with one of the most powerful Chains, the chain-killing Mad Hatter.
** Also, [[spoiler:Jack Vessalius counts, too. That sunshine demeanor and friendly attitude conceals a dangerous and insane underside. Same with Oz. Oz is also quite deadly when provoked. Try to insult Alice and he will cut you down with B-rabbit's scythe. Since he is also B-rabbit, that counts, too]].
** And we can't forget Vincent. He mostly comes off as dangerous to the audience, and a PoisonousFriend to Gil, his older brother, but to most of the characters he's that goofy noble who falls a sleep in the hallways due to an apparent lack of control over his power. ''Don't you believe it!'' He's cold and lethal, and if you try to hurt Gil, ''he '''will''' kill you''.
* Franchise/SailorMoon, especially in the first [[Anime/SailorMoon anime]]. Usagi Tsukino is a ditzy schoolgirl who cries, whines and eats a lot. But she's also a powerful MagicalGirl who will fight with teeth, nails and magic to protect those she cares for.
** Minako Aino / Sailor Venus, whom Usagi / Sailor Moon's character was [[{{Expy}} based off of]] is comically over-the-top, occasionally makes bad jokes, and uses {{Malapropism}}s like no tomorrow. She's also {{the leader}} of the Senshi, extremely powerful (''the'' most powerful of the inner guardian senshi in the manga), capable of scaring the arc villains senseless with her sheer power, and has a habit of brushing off excruciating attacks that cause all of the other Sailor Senshi to pass out from pain.
* Enji Koma of ''Manga/TokyoGhoul'' is a prime example of not judging Ghouls based on their every-day personality and looks. Most of the time, he's a goofy BigBrotherMentor to the other staff at Anteiku, and brags about being a RetiredBadass. He's generally dismissed by the younger employees, but proves he isn't all talk when [[spoiler: CCG raids the cafe]]. Turns out, he used to be the leader of one of the most infamous gangs in Tokyo and spending his days serving coffee hasn't dulled his strength in the least bit.
** In ''Tokyo Ghoul: re'', [[BlackSheep Sasaki Haise]] might normally be a goofy, bumbling PungeonMaster who's too soft on his subordinates, but catch him in the wrong moment and [[TheMentallyDisturbed he suddenly doesn't seem so approachable]]. [[spoiler: This is a side-effect of his [[SanitySlippage past self]] - Kaneki Ken - resurfacing whenever he uses his kagune.]]
* ''Manga/OnePunchMan'': Watchdog Man is a generic-looking guy dressed up in a [=McGruff=] knockoff suit who seems permanently out of it and apparently took the term City Watchdog way too literally. He also got assigned to ''the'' most dangerous city in the country because of his skill, and by the time they could ask him if there was anything to report, there really ''was'' nothing to report because he had already killed every monster.
** Saitama himself is a silly-looking bald guy wearing an even sillier-looking yellow costume. His superhero name is actually "[[EmbarrassingNickname Caped Baldy]]". He is often seen to be more preoccupied with his groceries or something else equally mundane rather than the MonsterOfTheWeek... but make no mistake: that's because he is at such a [[ComicallyInvincibleHero ridiculous power level]] that his mundane life is paradoxically more challenging than his superhero deeds. Threaten innocent people in his presence, and, well... you'll see for yourself why he is the main protagonist of a series [[ExactlyWhatItSaysOnTheTin titled]] ''[[OneHitKO One]] [[MegatonPunch Punch]] [[StoryBreakerPower Man]]''.
* Yukiko Kudo, mother of ''Manga/DetectiveConan's'' Shinichi Kudo, is frequently shown to be a ditz with a mischievous streak. She has proven time and again, however, to be a reliable ally in times of need. In the Mystery Train arc, she confronts an old friend who is a member of the bad guys' organization code named "Vermouth" and successfully distracts her long enough for a plan to fake Haibara's death to be implemented while convincing Vermouth that she had successfully stopped them.
* Every single recurring character from ''Manga/CityHunter'' has a measure of silliness, ranging from Kazue ([[OnlySaneMan the sanest one]]) having infiltrated a large corporation by getting engaged to the son of the CEO to Ryo's perverted and generally insane antics (when he got drunk and came home with various objects, a statue of Colonel Sanders, and a toddler, he and Kaori were surprised only at the toddler, because it was the first time he brought one home). All of them are also incredibly dangerous, ranging from Kazue being able to prepare poisons that kill you in five minutes or make you impotent to Ryo being a OneManArmy [[ImprobableAimingSkills who can use a revolver to put six bullets in the same hole at fifteen meters and a rifle to shoot a belt from one kilometer away]]. Even [[BigBad Kaibara]] is this: on one side he's almost as much of a goofball as Ryo, on the other he's one of the few men in the world who can match Ryo with a handgun and controls a gigantic syndicate.
* Shigechi from part 4 of ''Manga/JoJosBizarreAdventure'' in his first appearance wasn't threatening in the slightest. He's a fat, dimwitted, greedy kid, and his [[FightingSpirit Stand]], Harvest, is a large number of tiny figures that can seek and bring him small stuff. However, when he turned on Josuke and Okuyasu, he not only showcases how terrifying a Stand like his can actually be (fighting one big enemy is much easier then fighting hundred tiny ones), but also used surprisingly clever tactics that allowed Harvest to overpower both of them at the same time. In fact, even though both Josuke and Okuyasu have incredibly powerful Stands themselves, they had to resort to trickery to defeat him.
* Pandora's Actor in ''LightNovel/{{Overlord}}'' looks silly and acts so [[LargeHam hammy]] that Momonga is somewhat ashamed of having created him. However, as a powerful doppelganger, he can replicate any of members of Ainz Ooal Gown. While he can only use 80% of the originals' power, that makes him versatile enough to adapt to any situation and exploit any weakness.
* Several characters in ''Manga/ZatchBell'' have nonsensical powers that are nevertheless put to good use in battles of wit.
** Kanchome is a duck-billed boy in pajamas whose spells are all about trickery and illusions. Although cowardly and unconfident at first, he learns to stand for himself and protects his allies with clever use of his powers. Eventually he gains a spell that grants him [[spoiler:absolute control over a target's mind and is only defeated because of a cheap nuke shot from final villain Clear Note]].
** Belgim E.O and Unko Tintin are two giant undead themed demons who put the heroes through some hilarious situations, only for things to take a ''[[MoodWhiplash sharp]]'' turn for the worse as they turn out to be terribly dangerous opponents.
** Momon is a rabbit-monkey pervert boy who used his detection and mobility powers to avoid encountering enemy demons. When it's finally up to him to protect the main cast, though, he makes a fool out of Zeon and his underlings and successfully buys enough time for Gash and Kiyomaro to get back to the game.
** Purio is a {{gonk}}-looking demon kid who can only perform support spells that immobilize his enemies. He's quite a threat when providing backup for a powerful partner, but it's downplayed in that later on, while he does last to the top 10 of the King Tournament, he does so by avoid all combat [[spoiler:and goes down without a fight thanks to Clear Note]].

[[folder:Comic Books]]
* ''Franchise/{{Superman}}'':
** 99% of the time, Mr. Mxyzptlk just wants to use his awesome RealityWarper powers to play harmless practical jokes and be a funny pest. [[ComicBook/WhateverHappenedToTheManOfTomorrow As for that 1% of the time,]] ''be afraid.''
** ComicBook/LexLuthor [[DependingOnTheWriter varies]] from MagnificentBastard to IneffectualSympatheticVillain, but one shudders to think what might have happened had Franchise/{{Superman}} not stopped him all those times....
** The Toyman looks silly what with his huge bowtie and 19th century children's haircut, but back in the 90´s he killed Cat Grant's child.
** The gap-toothed Prankster also looks and behaves funny until he tries to kill anyone with his gimmicks.
** Since he's not right in the head, Bizarro will say or behave in an accidentally comical way until he displays his dangerous powers which mirror those of Superman.
* ''Franchise/{{Batman}}'':
** His [[RoguesGallery foe list]] has numerous villains who may be this way. For example, The Riddler mostly got into crime just to play mind games with Batman for fun. But from Commissioner Gordon's perspective, he's a MagnificentBastard.
** ComicBook/TheJoker is portrayed this way in some cases, too. Once he paid for doughnuts with play money with his face on it. Play money impregnated with his special formula, which was absorbed through the clerk's skin.
*** ComicBook/HarleyQuinn, though it varies more with her. It's easy to forget that she was a brilliant psychologist, and can revert to that personality to both apply those skills to mess with her opponent's head and to pass as normal far better than the Joker can. In her most recent incarnation, it's implied the Joker actually considers her more of a successor than a sidekick/girlfriend. Harley's issue of the ''Joker's Asylum'' series explicitly lampshades this. You do '''not''' want to stop her from getting to her "pudding" on Valentine's Day.
** ''Joker's Asylum: Penguin''. The Penguin was on a date, [[http://static.giantbomb.com/uploads/original/9/95848/1790556-jokersasylum_penguin_pg012_13.jpg when a chef laughed while looking in his direction]]. It might not even have been about him. He seriously considers murdering the guy with the steak knife until his date asks him what he's doing. He says it was nothing, puts down his knife, and they never speak of it again. Less than two months later, [[spoiler:the chef's life is systematically ruined, everything good in it has been destroyed or taken away from him, and he hangs himself in a bus station restroom]]. [[https://www.reddit.com/r/comicbooks/comments/1t9ea3/i_was_never_a_big_fan_of_the_penguin_until_i_read/ More discussion of the Penguin here]].
* [[ComicBook/NewGods Granny Goodness]] is laughed at for being an old lady super-villain, until you remember that 1. She's the only minion of Comicbook/{{Darkseid}} who doesn't get her ass kicked on a regular basis by super-heroes/Orion and 2. She's the Goddess of Horrific Child Abuse on Apokolips, which means that whenever she is not scheming against Darkseid's enemies, she's routinely crossing the MoralEventHorizon with young girls and boys. Being a super-villain is certainly a hard job and despite her age, she is still around, so you ''know'' she's good. Also, being around Darkseid for any amount of time and ''not'' getting the Omega Beams or Omega Sanction speaks volumes as to how dangerous she truly is. Just imagine how bad her abuse has to be for it to qualify as "horrific" ''on [[CrapsackWorld Apokolips]]''.
* Ragdoll from ''ComicBook/SecretSix'', no doubt. He's a master of the non sequitur, he's also perfectly capable of wrapping around you like a python and willing to snap your neck at the drop of a hat. He even gets a rant about people assuming he's just the comedy relief while attacking the rest of the team (and winning).
* Alfie O'Meagan from ''ComicBook/NthManTheUltimateNinja'' likes cookies and milk, plays video games, collects comic books, and has sandbox battles stomping on toy soldiers. Problem is, he's also a PsychopathicManchild RealityWarper...
* Mad Jim Jaspers from Marvel's ComicBook/CaptainBritain comics - ran around an alternate universe England with a gang of ludicrous criminals, committing ludicrous crimes... and happened to be a RealityWarper of such magnitude that his ''entire universe'' had to be destroyed to prevent the Jaspers Warp from contaminating the multiverse at large. And his main universe equivalent is even ''more'' powerful... ''and a member of Parliament.''
* Zodon from ''Comicbook/PS238'' is a {{Jerkass}} and the comic's bigtime [[TheChewToy Chew Toy]], with most of his plans ending him up in greater trouble than he started. Problem is, this is usually because one of the teachers or the students got in his way -- if they hadn't, the trouble -- and much bigger amounts of it -- would be someone else's.
** For an early example, Zodon's idea of a prank on Captain Clarinet was ''crashing an airplane full of passengers'', intentionally preying on his phobias of flight and failure just to [[KidsAreCruel make him cry]], and ''completely uncaring about the possible civilian casualties'' in the process.
* ComicBook/AmbushBug is a normal human in a ridiculous green suit amongst the gods of Franchise/TheDCU. In his heyday, he defeated a group of enemies with little to no effort while utterly humiliating them and could take on Superman or Supergirl before essentially defeating himself. Nowadays he's more relaxed.
* Comicbook/SquirrelGirl looks and acts doofy, has one of the silliest powers in comics, yet has defeated such omnipotent baddies as Doctor Doom and (seriously!) Galactus!
* The Violator from ''ComicBook/{{Spawn}}''. Taking the form of a pudgy clown, he's primarily around for comic relief. But at any time, the seemingly harmless clown [[OneWingedAngel can morph into a demonic killing machine]], easily capable of kicking Spawn's ass.
* ComicBook/PlasticMan is a zany, rubbery man who spouts silly jokes while having cartoonish adventures. He's also one of the most powerful members of the Franchise/{{Justice League|OfAmerica}}; even Batman, who has [[BetrayalInsurance contingency plans to neutralize any of the League members in case they go rogue]], is actively wary of him. On at least one occasion, he single-handedly took down a villain who had easily beaten Superman. When ComicBook/MartianManhunter turns into [[SuperpoweredEvilSide Fernus, the Burning Martian]], retaining his shapeshifting and Superman-level strength but losing his KryptoniteFactor, Plastic Man ''is'' Batman's contingency plan for that eventuality.
* ''ComicBook/{{Deadpool}}''. A madcap goofball with weaponized YourMom jokes who [[MediumAwareness thinks he's in a comic book and has conversations with his thought captions]]. He is also insanely good with every weapon known to man, sometimes to the Bullseye level where it's pretty much a superpower, and he has ConfusionFu going for him, as well as a Comicbook/{{Wolverine}}-class HealingFactor. He is an ''exceptionally'' deadly fighter and you ''really'' would rather have him on your side. Though people on his side tend want him to just ''shut up already'' even if he is the best they've got. Even Galactus could only take so much. People ''not'' on his side ''also'' want him to shut up already, not only because he's annoying but because he ''weaponizes'' annoyance: if you're paying to attention how annoying he is, you risk failing to notice the sword coming at your throat.
** That, and he's a CreatorsPet - and '''[[NoFourthWall knows it]]'''.
** Several characters have commented that it's a good thing that he ''is'' a silly one, and also genuinely tries to do the right thing (although his insanity means that his definition of the right thing is probably not shared by everyone else), and will not harm innocent people or allow them to be harmed. If he had Sabretooth's or Bullseye's personality [[ComicBook/DeadpoolKillsTheMarvelUniverse his body count would be astronomically higher]] and consist mostly of innocent people...
* ''ComicBook/{{Foolkiller}}'': In the limited series, Backhand, a local NY drug lord described Foolkiller as "crazier than ComicBook/ThePunisher...He don't come off like no soldier or cop. More like being yelled at by your momma or a preacher". Admittedly, it is rather silly to lecture the person that you are about to kill, as they don't exactly live to benefit from the lesson imparted. Some of his kills occur after a brief debate in which he pokes holes in the other person's argument, then calls them a fool, hence the name.
* Dr. Dinosaur from ''ComicBook/AtomicRobo''. He may seem silly and incompetent, but out of all of the villains not only is he the one who survives, but he survives Jenkins. Nobody else has been able to do that yet.
* ''Comicbook/{{Fables}}'' (being made up of fairy-tale characters) has a few examples.
** On the villainous side, we have [[TheWizardOfOz the Nome King]] who is initially an incompetent BloodKnight [[TheBrute brute]] to the Adversary. Upon getting power of his own he takes StupidEvil to new levels, and his legal system is so ridiculous that a defence attorney brags about how brilliant he is at his job because he's managed to get a relatively humane form of execution for his client (who hasn't actually had a trial, even a show-trial), but his insane slaughter of innocents is not played for laughs.
*** Mister Dark has TalkativeLoon tendencies so pronounced it's difficult to know whether he counts as FauxAffablyEvil or genuinely AffablyEvil, but since he is clearly introduced as a massive threat, they actually serve to make him creepier.
** On the heroic side we have Bufkin the [[TheWizardOfOz flying monkey]], who generally acts as comic relief with his gullibility, heavy drinking and simian interest in his own faeces, but as [[RetiredBadass a former captain]] of the flying monkeys and Fabletown's [[BadassBookworm main librarian]], he's a lot more dangerous than people realise when push comes to shove.
** Fabletown also has Flycatcher, who wears a goofy frog hat and is on permanent janitorial duty since he keeps eating flies. Then he founds an UndefeatableLittleVillage and defeats several powerful armies single-handedly, all while remaining a pacifist.
* ''ComicBook/TransformersMoreThanMeetsTheEye'': Brainstorm is by all appearances a typical MadScientist, suggesting and designing weapons of unspeakably insane intentions. Then he goes and causes stars to go out. And [[spoiler:then there's the fact that he's secretly a Decepticon agent, and all that wacky insanity is a coverer for a much darker personalityƒ]].
* In ''ComicBook/TheMultiversity'', ComicBook/{{Captain Carrot|AndHisAmazingZooCrew}}, as bizarrely amusing as he may seem, is no slouch when it comes to heroics or combat. This became apparent in the very first issue, when he [[NoSell nonchalantly shrugged off]] an attack from Earth-8's Behemoth (an {{Expy}} of ''the freaking [[ComicBook/IncredibleHulk Hulk]]''), then proceeded to [[CurbStompBattle knock him flat on his ass]] [[OneHitKill with one punch]]. You don't argue with CartoonPhysics.
* Negan from ''ComicBook/TheWalkingDead'' is an eccentric, AxCrazy {{Cloudcuckoolander}} who swear a lot, thinks of the most random things to say off the top of his head, has an over-the-top personality that confuses his own followers, and likes to speak to his baseball bat [[CompanionCube Lucille]] as if it were a person, [[CargoShip mentioning how she turns him on when she strikes]]. However, he's also one of the most infamous villains to enter the series and is a credible badass HeroKiller.

[[folder:Fan Works]]
* Keeper [[CrazyAwesome Mukrezar]] is a pink-haired elf who comes across as fairly likable, and despite a less-than-perfect record for succeeding in his many, many [[ZanyScheme schemes]], he clearly has a lot of fun with his chosen profession. He is also one of the most cruel and sadistic [[FanFic/DungeonKeeperAmi Keepers]] in history and is responsible for transforming the idyllic Avatar Isles into a volcanic toilet.
* Socrates, normally the {{Cloudcuckoolander}} and JerkWithAHeartOfGold among the heroes of ''Fanfic/CalvinAndHobbesTheSeries'', still has his moments of seriousness. Probably the most [[OutOfCharacter jarring]] moment he's had is the entirety of "Have You Seen This Tiger?", wherein he becomes extremely angry for the first half.
* [[PrivilegedRival Obsidian]] from the HungerGames fanfiction ''Fanfic/SomeSemblanceOfMeaning''. When heroine [[BrainyBrunette Vale]] first meets him in the Training Center, he comes off as rather silly, with his friendly, if a bit superior, attitude toward Vale and his [[AttentionDeficitOohShiny comment about being like a magpie and liking shiny things]]. He isn't seen exhibiting any skills with a weapon... and then, he gets the highest training score of all twenty-four tributes. To say nothing of the serious and competent skill he displays in the bloodbath.
* The ''FanFic/PonyPOVSeries'':
** Discord, [[UpToEleven even more so]] than in canon.
** [[GeneralRipper General-Admiral Makarov]], the BigBad of the Shining Armor Arc, is a LargeHam PsychopathicManchild who flies off the handle for the smallest things. However, he's also the leader of one of the largest militaries on the planet, with advanced (for the setting) technology that he's not adverse to using, will kill anyone for [[EvilIsPetty the pettiest reasons]], and is strong enough to deliver a NoHoldsBarredBeatdown on Shining. And then, its revealed that [[spoiler: he's an [[HumanoidAbomination Equineoid Abomination]] with RealityWarper powers]], and that his endgame involves a war to take over the world and multiple acts of ''genocide''.
* This and OOCIsSeriousBusiness are used horribly effectively in FanFic/TheMeasureOfATitan with Starfire. When she is upset enough to go out looking for criminals to brutally beat each night until she passes out from exhaustion, so much so that the crime rate drops as all the baddies try to stay under the radar, it cannot be a good thing.
* [[Fanfic/KingdomHeartsNewEpicTheFirst Wolfang Richler]] does not seem like a very imposing villain at first, despite using his magic to blast off a statue's head. He babbles to himself, he seems to not believe people let themselves age, and his interactions with Jonahs paint the picture of a very lonely, ''immensely bored'' immortal. When Jonahs joins back up with his friends, we learn [[spoiler: Wolfang turned two guards to stone, simply for getting in his way, and later in the same chapter seems to teleport all over the place, kills people with absurd ease and nonchalance, and during his conversation with Sarasho, we see he wants to set up ''a universe wide civil war'']].
* Heroic example from Fanfic/PokeWars. Mew is an immature, childish and just plain ''silly'' Pokémon. However, he ''is'' a [[OlympusMons Legendary]] ''and'' one of the more powerful ones too. His powers include [[VoluntaryShapeshifting changing into any Pokémon he desires]], command of ''all'' known Pokémon attacks and [[{{Teleportation}} at will teleportation]].
* Ahuizotl in ''Fanfic/TheTwoSidesOfDaringDo''. He's a LargeHam who's just as over the top always...and also a sadistic psychopath and KnightOfCerebus who's plots are less about conquest and more about [[OmnicidalManiac destruction]] ForTheEvulz. He's also a frighteningly powerful physical opponent with SuperStrength [[spoiler:and a straight up LightningBruiser when in the water. In a straight up physical fight, he [[NoHoldsBarredBeatdown he beats the hell out of both Daring Do and Yearling]] and leaves them both with broken bones]]. He still puts Daring Do in death traps...because he wants to leave her DyingAlone in a slow, horrible fashion. AK Yearling outright says that he's such a monster that she ''had'' to play him for laughs so her producers would let her keep him in.
* In ''Fanfic/HopeForTheHeartless'', two of the invisible creations of [[CosmicEntities the Fates]] are described this way. They're nearly all the time [[GreatGazoo fun-loving]] and optimistic [[ThePrankster prankster]] sidekicks who squeeze enjoyment out of nearly every situation, no matter how bad it might be. However, [[BerserkButton if you touch something they care about, they instantly turn into something Mother Nature herself couldn't rival in vindictiveness and malice]].
* Aiko Uzumaki, the main character of ''{{FanFic/Vapors}}'' is very much this. In her downtime off of missions, she writes fantasy stories, uses glittery vanilla shampoos, and happily goofs around with her friends while she can. She is also the personal apprentice of [[TheAce Hatake Kakashi,]] [[AwesomenessByAnalysis responsible for foiling several of Akatsuki's plans,]] [[ScrewTheRulesIHaveConnections on first name terms with three kages and three jinchuriki,]] and was labeled an [[TheDreaded S-class threat]] before her sixteenth birthday.
* In ''FanFic/SonicXDarkChaos'', Eric the Hedgehog is definitely this. Sure, he seems like a harmless crazy version of Sonic at first glance... until he unleashes his machines. And his ''[[IdiotSavant starships]]''. And his Super form -which allows him to [[MoreDakka create huge guns from thin air]]. [[spoiler: Oh, and it's implied he's [[HumanoidAbomination far more than just a loony on top of that]]]].
* ''Fanfic/DantesNightAtFreddys'' is a crossover fic that features [[VideoGame/DevilMayCry Dante]] having to do a stint as a night watchman at [[VideoGame/FiveNightsAtFreddys Freddy Fazbear's Pizza]] after taking his young daughter there for her birthday and subsequently putting his fist through an arcade machine. Even in his fifties and deprived of his weapons, the haunted animatronics are [[CurbStompBattle absolutely no match]] for Dante, who ends up killing all four of them in incredibly silly and ironic ways. Such as killing Bonnie by [[spoiler:repeatedly crushing her head with the door and punctuating each impact with a sarcastic "Whoops"]], killing Chica by [[spoiler:frying her with electric wiring]], and killing Foxy by [[spoiler:gouging out Foxy's eye with his own hook hand and then carving him up with his own teeth, all the while taunting him in pirate speak]].
* In ''[[https://www.fanfiction.net/s/11962940/1/ A Brighter Dark]]'', the main character [[FireEmblemFates Corrin]] can be a bit hard to take seriously at times. [[HardDrinkingPartyGirl She drinks,]] [[ReallyGetsAround sleeps with pretty much any man who asks,]] [[BookDumb has trouble with her studies,]] [[SirSwearsALot and has never heard a curse word she didn't like.]] Nonetheless, get on her bad side, and she will utterly annihilate you with her sword skills.

[[folder:Films -- Animation]]
* In ''WesternAnimation/KungFuPanda'', Tai Lung's attempt to kill Master Shifu was interrupted by Po. The snow leopard scoffs at the idea that this comical panda could possibly be the Dragon Warrior, only to find out the hard way that he most definitely is!
* Disney's Willie the Giant from ''Disney/FunAndFancyFree''. In the first scenes of the ''Mickey and the Beanstalk'' segment of the film, Willie is introduced as a terrifying kleptomaniac who seems more storm cloud than giant. In his second entrance, he appears as a goofy shapeshifter with a fondness for [[RealMenWearPink pink bunnies]], and an inability to pronounce the word "pistachio." Oh, and he's also a BigEater who almost [[ImAHumanitarian accidentally eats]] the Disney power trio of WesternAnimation/MickeyMouse, WesternAnimation/DonaldDuck and WesternAnimation/{{Goofy}}. [[TemptingFate But don't confuse his playfulness for dimwittedness]] like Mickey, Donald and Goofy tried to. Count yourself lucky if he keeps you as a literal souvenir in a box, rather than squishing you like an insect. And when Willie gets really riled up, he also wields an iron morning star the size of a two-story house.
* ''Disney/WreckItRalph'''s King Candy doesn't look all that intimidating at first glance. He's basically a CGI {{Expy}} of the Mad Hatter. [[spoiler: But then comes TheReveal and by the time the movie ends, you ''will'' believe the Mad Hatter can be a legitimately dangerous villain.]]
* ''Disney/TheLionKing'': Ed. Sure, he seems goofy and bumbling, with that laugh and blank wall-eyed stare, but Scar found out the hard way he can be deadly serious.
* ''Disney/RobinHood'': Prince John is [[ManChild extremely infantile]], but if you mock him badly enough, he will ''not'' let you get away with it.
* Flik from ''WesternAnimation/ABugsLife'' is a light-hearted clown for most of the movie, but has a darker side which shows itself at the end when he tricks the BigBad into getting himself killed.
* Dave the Octopus from ''WesternAnimation/PenguinsOfMadagascar'', is more than a little off his rocker, but the fact that he was able to concoct such a plan, gather an army of minions, and create that entire base as well as a human alter ego pretty much cements him into this trope.

[[folder:Films -- Live-Action]]
* Tuco (The Ugly) of ''Film/TheGoodTheBadAndTheUgly'' may be a LaughablyEvil goon, but he is every bit as dangerous as Blondie (The Good) and Angel Eyes (The Bad), nearly killing them both on several occasions. Prior to the final shootout, [[spoiler:Blondie makes sure to empty Tuco's gun rather than face him in a gunfight]].
%%* Several of the characters in Creator/TimBurton's ''Film/AliceInWonderland2010'', perhaps most particularly the Mad Hatter, fall into this trope.
* Yoon Tae-Goo (the Weird) of ''Film/TheGoodTheBadTheWeird'' qualifies. He provides most of the comic relief and is more prone to amusing mishaps than the Good and the Bad, but this does ''not'' mean he isn't capable of being incredibly dangerous. (Fittingly, he's an {{Expy}} of Tuco.)
* In ''Film/TheHobbit'', with the exception of Thorin, all the dwarves in the company range from mildly goofy to downright mad at times. But they are ''all'' a force to be reckoned with when it comes down to a fight. Radagast the Brown is absent-minded and has bird poop in his hair but there is a reason why he is one of the most powerful wizards in Middle Earth, including banishing a herd of attack spiders from his home, brings a hedgehog back from the dead, leads a pack of wargs on a merry chase and [[spoiler: manages to fend off ''the Witch King''.]]
* [[BigBad Komodo]] from ''Film/WarriorsOfVirtue'' needs to be ''[[https://www.youtube.com/watch?v=0i99ovxEGVU seen to be believed]]''. He drops ''all'' the E and just [[PsychoticManChild runs]] [[IncomingHam full]] [[NoIndoorVoice throttle]] every step of the way. However, without giving much away, there's are numerous '''very''' good reasons everyone is [[TheDreaded terrified of the guy]]. It's no surprise that, in an otherwise poor film, he's the [[HamAndCheese most entertaining and memorable part]].
* ''Film/MrRight'' is about an {{Adorkable}} CloudCuckoolander of a young woman named Martha who encounters the titular character, a reformed hitman named Francis who goes around killing people that try to hire him as an assassin because "killing is wrong." His gimmick is wearing a red clown nose while doing this, he dances everywhere, he's a total CloudCuckoolander, and thanks to his ability to see the world in BulletTime and his ridiculous reflexes, he is ''unbelievably'' deadly. [[spoiler: It turns out that part of the reason he was interested in dating Martha is that he could sense that she could do what he does (which he demonstrates by throwing knives at her and her automatically catching them), and by the end of the film she is just as deadly as he is, with her own silly gimmick to go along with her deadliness (cat ears, in her case)]]

* Mr. Croup in Creator/NeilGaiman's ''LIterature/{{Neverwhere}}'' even {{lampshade|Hanging}}s that just because something is silly doesn't mean it can't be dangerous. Then he and his associate Mr. Vandemar crucify the person who found them funny. While arguing whether circumlocution is a grammatical technique or a body part. (The former, if you were wondering.)
* Warlord Zsinj is like this in ''Literature/TheCourtshipOfPrincessLeia'', but in the ''ComicBook/XWingSeries'' we see it's only as a cover. He goes to extraordinary lengths to convince people that he is a foolish, {{fat|Idiot}}, mustachioed criminal, while [[ObfuscatingStupidity underneath he is a talented, experienced strategic genius]].
** His [[NumberTwo second-in-command]], General Melvar, almost goes to the opposite extreme. The persona he shows everyone but Zsinj is almost extraordinarily cruel, sadistic, and an AxCrazy idiot. When they're gone, his features are curiously bland, he enjoys startling his Warlord, and he's a DeadpanSnarker. They'll both [[KickTheDog kick puppies]] like there's no tomorrow, but they're more businesslike about it.
** For the good guys, Wes Janson. Happy-go-lucky prankster, ManChild extraordinaire, friendly with all of his squadmates...and [[ImprobableAimingSkills able to shoot an enemy dead with one blaster pistol shot at a hundred paces]]. He's normally a FriendlySniper, but when he's in a pinch, he's [[ColdSniper all business]].
* Count Fosco in Creator/WilkieCollins' classic sensation novel ''Literature/TheWomanInWhite'' is the Victorian-era poster boy for this trope.
* ''LIterature/{{Discworld}}'':
** Nanny Ogg in ''Literature/{{Discworld}}'' is a prime example, looking like an amiably-wrinkled, sexual-innuendo-prone old woman, with a mind like a razor. She's been Granny Weatherwax's friend since they were girls.
** Otto von Chriek from ''Discworld/TheTruth'' speaks in HEAVILY accented VampireVords, throws in a blah here and then (blah), is addicted to flash photography, which is bordering on a suicidal hobby for a vampire, and towards the end of the book clears a room of armed guards before ending it with a kiss to the forehead of their employer.
** Lampshaded in a later book when someone realizes that Otto does this deliberately to blend in.
---> Little fussy Otto, in his red-lined black opera cloak with pockets for all his gear, his shiny black shoes, his carefully cut widow’s peak and, not least, his ridiculous accent that grew thicker or thinner depending on whom he was talking to, did not look like a threat. He looked funny, a joke, a music-hall vampire. It had never previously occurred to Vimes that, just possibly, the joke was on other people.
** Pepe from ''Discworld/UnseenAcademicals'' seems like a goofy, CampGay fashion designer, but that's only when he's on the job. Off the clock, he's a hard-drinking, wise-cracking, street-smart fellow who's a veteran of the mean streets of Ankh-Morpork. What plants him firmly in this trope is a scene at the end of the book where [[spoiler: Pepe corners street thug Andy Shank in a dark alley and ''[[EyeScream carves out an eye]]'' as a warning to leave Trev Likely and his friends alone]].
* ''Literature/TheDresdenFiles'': Harry Dresden is perpetually sarcastic, spouting pop culture references at the drop of a hat and is generally quite friendly. He is also [[TheDreaded powerful enough to give the Senior Council pause]].
* ''Literature/AlbertCampion'', protagonist of most of Margery Allingham's books. He might act like a silly ass, natter on about his mouse's birthday, and compulsively make jokes, but you should never underestimate his mental or physical capabilities. ''Ever''.
** Also, [[spoiler: Alastair Barber]] from [[spoiler: "Mystery Mile"]] who appears to be an embarrassingly-talkative bore who has a penchant for throwing food at acquaintances, is actually the BigBad who runs a criminal network that is feared across continents.
* Similarly, ''LIterature/LordPeterWimsey'' plays the idiot man about town to the hilt, including carrying the requisite cane and monocle, and babbling on at the drop of a hat. The cane and monocle are secretly tools. Lord Peter is unstoppable as a detective. And it is seldom mentioned, but he is a war hero.
* While Bast's lighthearted and, well, ''silly'' demeanor often provides some much-needed comic relief in ''LIterature/TheNameOfTheWind'', you really ''do not'' want to get on his bad side. As a Fae, he often cares only for his own whims and desires... and he will happily [[CutHisHeartOutWithASpoon string a fiddle with your guts and make you play it while he dances]], should you get in his way.
* In ''[[Literature/{{Paranormalcy}} Supernaturally]]'', Jack seems to act like an immature teenager. He uses his PortalDoor ability to appear in a girls' locker room and to appear in Evie's room to jump on her bed. [[spoiler: However, he is secretly behind all the random paranormal encounters that Evie keeps having, because he wants to use her to get rid of the faeries. When she doesn't agree to do this, he banishes her into the Faerie Paths.]]
* In ''LIterature/{{Foundation}} and Empire'', Magnifico Giganticus appears first as a rather pathetic clown before being revealed as [[spoiler: a mutant telepath known as the Mule who conquers a significant portion of the galaxy and nearly destroys the titular Foundation forever]].
* CampGay [[TheDandy Dandy]] Lord Akeldama in ''LIterature/TheParasolProtectorate''. He might dress outrageously and live in an overdecorated townhouse with a horde of PrettyBoy drones, but he's still a very old [[OurVampiresAreDifferent vampire]]. And those drones of his? He's trained them to be so effective at collecting gossip that he often knows more than the actual ''government''.
* ''Literature/{{Animorphs}}'':
** SixthRanger and [[AlienAmongUs resident alien]] Ax is frequently played up as a comedic character, his infatuation with taste and tendency to play with sounds used for easy laughs. But when push comes to shove, Ax is ''the'' most dangerous of the Animorphs, beating out even [[BloodKnight Rachel]]. His feats include killing a rogue crocodile in ''The Reaction'' (after it beat half the team), defeating [[BigBad Visser Three]] in single combat as early as ''The Decision'' and even killing a Tyrannosaurus Rex in ''In the Time of Dinosaurs''. This is highlighted pretty effectively in The Separation, when even [[SuperpoweredEvilSide Mean Rachel]] doesn't want to tangle with him.
** And of course, Marco. The team's resident clown (if somewhat of a [[SadClown sad one]]), he spends half of his time making bad jokes and the other half viciously picking apart every plan of his friends and his enemies. In terms of planning he is the most ruthless Animorph--he [[IDidWhatIHadToDo does what he has to do]], up to the point of once pushing his own mother off of a cliff. (She's the host body to [[EvilOverlord Visser One]]. [[JokerImmunity And they both survived, anyway]].)
* Oh, no. Literature/HerculePoirot is investigating those murders I committed. But wait, he seems to be bumbling, he's very much the funny foreigner, and he's fallen for my {{Red Herring}}s. Maybe he's lost his touch with age. I think I'm [[KarmaHoudini safe]]. I--[[OhCrap What the]]? How did he figure out... Damn! He got the goods on me for this murder and then tricked me into revealing what he hadn't known for sure.
* In Lois Lowry's novel ''Literature/NumberTheStars'', Annemarie (at her mother's directions) acts like a "silly, empty-headed girl", convincing the Nazi soldiers that's what she is, instead of someone carrying a package vital to the Resistance.
* In ''Literature/ChroniclesOfAmber'', in ''Knight of Shadows'' when Merlin is pursued by a ghost construct of a Chaos Lord he asks the ghost construct of Benedict to buy him time. Benedict stalls for time waving his sword seemingly with none of his usual precision, cutting off enemy's buttons and occasionally pinching the enemy's nose. He's that much better. Also of note is that Benedict, Merlin and some others often use fencing techniques with wild and deceptively crude swings.
* [[Literature/TheCinderSpires Master Ferus]], Etherealist. Clear {{Cloudcuckoolander}}. Forgets to wear his clothes at home, sometimes. Can't operate doorknobs. [[note]]" They're extremely complex technology!"[[/note]]. And when his home is invaded, [[spoiler:he draws enough 'etheric' energy through their gauntlets that it melts all of the copper wiring within them; this is then... forcibly returned. The resulting charred corpses are horibble enough to give his apprentice NightmareFuel without even looking]].
* Curdle and Telorast, two ghosts possessing the skeletons of tiny dinosaurs in the ''Literature/MalazanBookOfTheFallen'', are presented as wacky comic relief for the first two books they appear in. Then ''Literature/DustOfDreams'' hits and reveals them to be ancient [[spoiler: dragons]] who almost succeeded in conquering the [[spoiler: Throne of Shadow]].

[[folder:Live-Action TV]]
* ''Series/BuffyTheVampireSlayer'': You honestly wouldn't consider Glory a threat, at least a major one, if you weren't aware of her strength or that she is a GodInHumanForm.
* The Doctor of ''Series/DoctorWho'' just wants to have a bit of fun. "There's no point in being grown up if you can't be childish sometimes," he says. He's been accurately described as a "madman with a box", and no one with his dress sense (no matter how much it changes) could ever be taken seriously. He's also stopped more villainous plots and saved more lives than could possibly be counted, and is outright ''[[TheDreaded feared]]'' by some of the most evil beings in existence.
** As befitting an EvilCounterpart, the Master sometimes shows shades of this. The Anthony Ainley and John Simm incarnations especially loved to bust out the EvilLaugh and add some flair to their villainy, but there is a very good reason the Doctor continually regards him as his worst enemy.
* ''Series/{{Sherlock}}'''s Jim Moriarty. Criminal mastermind. Also, one of his first lines was an OrAreYouJustHappyToSeeMe joke.
** Ironically, even though Sherlock's not a [[PluckyComicRelief Plucky Comic Relief]] he could count as well. Uh, let's see.....[[NightmareFetishist keeps a skull]] (''weird''), [[ManChild acts like a child]] and is a ''very'' [[InsufferableGenius intelligent detective.]] Oh, and he does [[BunnyEarsLawyer VERY kooky things]] to solve cases.
** Piss him off by [[BerserkButton threatening his friend's life]] in front of him-and [[BewaretheQuietOnes you're screwed.]]
** Mary seems to be sweet and goofy. She ''was'' [[BewareTheNiceOnes an assassin from the CIA.]]
* ''Franchise/PowerRangers''
** In the [[Series/MightyMorphinPowerRangers original show]], Squatt and Baboo didn't do much except go on errands and mess up while doing it. But in one episode they took initiative on their own and built their own monster, the result of which, a turtle-like creature named Shellshock, was a ''terror''. He had a stoplight mounted atop his body that could cast a freeze ray from the red light and a speed ray with the green one and had a veritable Swiss army knife of weapons stored in his shell. The first battle was a disaster for the heroes; he froze most of them with his red beam and made Trini unable to stop running with his green one. (Even worse, this made her the only one able to look for the cure, which she managed, despite Rita making it even harder with a squad of Mooks getting in the way.)
** In the second season, some cases of NearVillainVictory came at the hands of some pretty ridiculous Monsters of the Week.
*** Beamcaster was a radio-themed monster who spoke like some weird DJ, but used MindControl to entrance the whole city, and even hypnotized the ''entire team''. To fight him, Zordon had to call up Rocky, Aisha, and Adam (who had not yet taken up the mantle) and get them to help, a prelude to the episode where Jason, Zach, and Trini, would [[PassingTheTorch Pass the Torch]] to them.
*** Scatterbrain was even sillier-looking. Created by Lord Zedd from a kaleidoscope, he was a… guy with a really big kaleidoscope for a head. Still, his memory wiping power got the entire team, and this time, ''Bulk and Skull'' were the ones who got the heroes out of the mess, albeit by accident. (Sadly, they were affected slightly too, so although they were the heroes, they didn’t remember it.)
** When Rita teamed up with Zedd, they didn't do much better as a team then they did alone; with a few exceptions:
*** In one episode, Rita tried to use a spell to turn Kat into her slave again, but ''missed''. She hit a wall instead, creating a monster called the Brick Bully. He looked ridiculous, but it seemed this monster by misfire was pretty potent. His first battle with the heroes resulted in him turning all of them except Kat and Billy into bricks (or rather, [[AndIMustScream reducing them in size and sealing them inside bricks]]) and while Billy tried to find a way to reverse the effect, he didn't just sit around. He started consuming bricks and cement, [[OneWingedAngel turning into a stronger monster.]] Billy had to confront him alone to prevent him from getting stronger, ultimately taking him down in his own CrowningMomentOfAwesome. Still, it was a brutal fight.
*** And that wasn't the last "monster by misfire" that resulted in a problem. During ''Series/PowerRangersZeo'', Rita tried the same thing, but missed Kat again (clearly her aim hadn't improved) hitting her purse. (Ironically, a homemade one she didn't like.) The Impursonator was the result, and she was clearly the strongest monster Rita had ''ever'' created, despite looking relatively harmless. The Rangers couldn't ''scratch'' her, not with their handheld weapons or their Zords, her rubbery skin making her impossible to hurt, and even worse, when King Mondo's monster appeared, she was able to hijack the Super Zeo Megazord and take it for a joyride! (Fortunately for the city as a whole, Mondo's monster had stolen the other one - as it had been designed to do - [[EnemyCivilWar and they decided to fight each other for a while]].) Ultimately (after a two-parter) she combined with Mondo's monster, and was dispatched via the combined efforts of ''three'' Megazords working together.
** Lothor of ''Series/PowerRangersNinjaStorm''. He spends most of the series sitting on his throne and cracking meta-jokes while his henchmen fight the Rangers for him, but is still a dangerous opponent whenever he can be bothered.
** Divatox of ''Series/PowerRangersTurbo'' probably takes the cake. Screechy enough to make Rita sound like Beyonce, completely incompetent, and managed to MindWipe ''herself'' on one occasion. Then [[LetsGetDangerous the season finale happened...]]
* Rudy of ''Series/KickinIt'' is your standard Disnick KidCom AdultChild BigBrotherMentor, unless something ''really bad'' is about to happen at which point the writers remember what a third-degree black belt karate instructor's supposed to be capable of.
* Jack O'Neill of ''Series/StargateSG1'' likes to play dumb and joke around, but gets things DONE. Also, his irreverence and jokes frequently annoy the Goa'uld and their Jaffa, who are infuriated because Jack doesn't take them seriously. This is, possibly, his intention, although it fails to work on the GenreSavvy Ba'al.
* Fran Fine, ''Series/TheNanny'', may come off as nasal, big-haired, and desperate, but, people tend to forget she is also a hypermanipulative master of the CoolAndUnusualPunishment, most often in the form of forced proximity with her [[MyBelovedSmother overbearing mother]]. She's also skilled with Jewish guilt, and can reduce feelings of triumph to bitter sadness with a snap of her fingers.
* Series/{{Merlin|2008}} is the PluckyComicRelief of the knights who [[ButtMonkey is constantly abused for laughs]], but beneath the joking exterior is an extremely dark AntiHero who's also a PersonOfMassDestruction. Arthur and most of Camelot are unaware of this. It's also a bad idea to [[BerserkButton threaten anyone he cares about!]]
* Rygel from ''Series/{{Farscape}}'' is a deposed Hynerian (small, toad-like creatures) royal with an ego the size of a dwarf star and a tendency to either flee from battle or fart helium when pressed into a corner. He's also, at times, killed the man who spent years torturing him and paraded his head about on a stick, and tortured captive enemies to death for information.
** Then there's "Coup by Clam," where Rygel has officially had ''enough'' of a blackmailing poisoner's shit, and thus [[spoiler: ''bites his nose off'', then poisons him in such a way that he can't possibly cure himself]].
* Walter Bishop from ''Series/{{Fringe}}'' is a somewhat addled old man who constantly gets the name of his FBI overseer wrong, has an unquenchable taste for a different food each week, and often consumes drugs of his own making. In this context, it's somewhat hard to remember he was consigned to an asylum for years after a lab experiment that killed several of his assistants. [[spoiler: And, when he's hooked up to the parts of his own brain, removed to destroy extremely sensitive knowledge, he shows how much of a righteous bastard he once was.]] He can also bring the fury in his current state - in "The Bishop Revival," he finds an ageless Nazi scientist has been using his father's research to design aerosolized poisons that target certain genetic markers. His response, in turn, is to design his own toxin, track the man down at a conference on peace and tolerance he'd been planning to target, and passionlessly cause him to asphyxiate in the middle of the gathering.
* Uncle Howee from ''Series/TheHauntingHour'' episode of the same name. He's a wacky, over the top children's performer who acts alongside his puppet rabbit and clock man in a cartoony fashion. However, when his number one fan Cynthia is bullied by her big brother Jared while he babysits her and immediately tries ditching her to hang out with his friends, Uncle Howee leaves his fictional world and enters the real world where he uses his RealityWarper powers to punish Jared for his cruel behavior. [[spoiler: It ends with our clownish children's performer dragging Jared back into his show, where the bully [[AndIMustScream is turned into a lifeless puppet forced to entertain on his show forever]].]]
* Alfie from ''Series/HouseOfAnubis'' may be the class clown, but he's no pushover, as he has proven to be a useful presence in Sibuna- and if he is serious about something, you better not stand in his way. He yelled at Fabian and Patricia when they wanted to have breakfast instead of rescuing the currently-trapped Amber, and then later was the one standing up against [[TheSoulless Sinner!Fabian]]- to the point of pressing Fabian's BerserkButton and getting away with it.
* Pheobe Buffay from ''Series/{{Friends}}'' may seem like a sweet GranolaGirl with a kooky sense of humor, but she was tough enough to mug older boys when she was just a teen living on the street.
* Rick Castle of ''Series/{{Castle}}'' fame is a fun-loving geek of a bestselling mystery author, prone to coming up with ludicrously outlandish theories on the murder of the week. Threaten Beckett, or worse [[PapaWolf his daughter Alexis]], and ''you're done'': he's shot three criminals and [[spoiler:used the JackBauerInterrogationTechnique on one of his daughter's kidnappers]].
* Officer Schnabelbach ([[MeaningfulName River of Spouts]], referring to his MotorMouth) in the German crime series ''Morgen hör ich auf'' (loosely inspired by ''Series/BreakingBad'') is introduced as [[PoliceAreUseless yet another ineffectual police officer]] with fondness for smalltalk and [[CasanovaWannabe charming women]] but his third appearance establishes him as the criminal police's OnlySaneMan who found a hint to the protagonist's crimes and correctly suspects them.
* [[MadScientist The Mads]] of ''Series/MysteryScienceTheater3000'' are usually just AffablyEvil [[HarmlessVillain Harmless Villains]], but they all have their moments of genuine evilness.
* Shawn Spencer from ''Series/{{Psych}}'' is a perfect example of this. A complete jester who never takes anything seriously and seems harmless enough...until his loved ones are put in harm's way. Then he will hunt you down until you're "behind bars or dead". [[spoiler:quoted from an episode where Shawn takes down the man who shoots his father]].
* Q from ''Series/StarTrekTheNextGeneration'' generally acts arrogant and snarky, but he's still a RealityWarper with god-like power and if you piss him off, he can and will use those powers to screw with you. Perhaps the best demonstration came from his single appearance in ''Deep Space 9'', after Sisko has demanded that Q leave the station:
-->'''Sisko:''' Perhaps you and I should continue this discussion in private.
-->'''Q:''' ''Excellent'' idea. ''(Everyone but the two of them vanishes)'' You were right! This ''is'' an excellent idea!
-->'''Sisko:''' Sisko to ops. ''(There is no reply)''
-->'''Q:''' ''(quietly menacing)'' All gone.
* Negan from ''Series/TheWalkingDead'', much like his comic book counterpart, is the most odd person to ever enter the series since he is a random {{Cloudcuckoolander}} who cusses like there's no tomorrow, talks to [[CompanionCube his lucky bat]], and puts on a goofy front, but he nonchalantly threatens Rick's BadassCrew into kneeling before him after he personally executes [[spoiler: their friends Abraham and Glenn]] by [[CruelAndUnusualDeath beating them to death with his baseball bat covered in barbed wire.]]
* [[LargeHam Douglas]] from Series/TheITCrowd may or may not have killed his first wife.

* Norman Sheffield was the first manager of the band Music/{{Queen}}, and (allegedly) decided to take financial advantage of the newly-famous musicians, naive to the world of recording contracts and such. The leader of these goofy longhaired glam rockers later wrote "Death on Two Legs", which he said was "Dedicated to a [[PrecisionFStrike motherfucker]] of a gentleman", and filled with so many acidic insults it was essentially a musical TheReasonYouSuckSpeech.

[[folder:Pro Wrestling]]
* A case of HoistByHisOwnPetard: Sometimes, {{Heel}}s in Wrestling/{{ECW}} would throw out open challenges and the worst they would leave with was a bruised ego. After Justin Credible d. Chris Chetti at ''ECW Ultimate Jeopardy 97,'' November 8, 1997 (televised on the November 15th show), his manager [[TheFightingNarcissist Jason "The Sexiest Man on Earth"]] got on the mic and talked about how, out of 30 or so guys in the locker room, he was one of the few who could actually wrestle and that "it sucks" only working as a manager. So, since he was in his "street clothes," he issued an open challenge for a "street fight." Cue "Let Me Clear My Throat" by DJ Kool, and out comes...Wrestling/TheBlueMeanie with [[Wrestling/MikeBucci Super Nova]]? Jason dismisses Meanie at first, but finally agrees. While it's not much of a match, and even less of a "street fight" (referee John [=Finnegan=] blocks Meanie from attacking when Jason ducks his head through the ropes), it qualifies as Jason basically treats Meanie as a joke the whole time...until Meanie [[GroinAttack comes up with a testicular claw]] into a schoolboy rollup for the pin! (For an example of how much worse this could have turned out for Jason, see [[TooDumbToLive/ProWrestling Too Dumb To Live]].)

[[folder:Puppet Shows]]
* Miss Piggy, full stop. She's a veritable empress among drama queens, insufferably vain, yet charmingly foppish, and is constantly comedically pining for the love of her employer, Kermit The Frog, who, half the time, doesn't notice her affections, and the other half is living in mortal fear of her affections. But, don't forget that a large part of her charm is that she's also a take-charge ActionGirl who can become a PersonOfMassDestruction at the drop of a (designer) hat. Plus, don't press her [[BerserkButton buttons]] if you want to live, i.e., don't insult her or her abilities, [[AndYourLittleDogToo don't ever threaten her loved ones]], and most importantly, [[ArsonMurderAndJaywalking don't make pork jokes in her presence]]. [[TooDumbToLive Well, you can if you want to,]] but, as ''Film/TheMuppetMovie'' demonstrated, she'll then open a six-pack of extra-strength whoopass on your minions, and violently install you in your own MindRape device with extreme prejudice.

[[folder:Tabletop Games]]
* The ''TabletopGames/YuGiOh'' game has its share:
** Wind-Ups are a bunch of cards that look like CuteMachines, but once had a strategy called a "Wind-Up Lock" so lethal that several of the key cards were Limited or Banned completely.
** Gadgets are cards with monsters that look like {{Funny Robot}}s, and yet, they were once part of the obscenely-powerful "Crumbling Tower" strategy that required them to be Limited and Elemental Hero Stratos Banned.
** The Madolche are monsters that look like the residents of some cloyingly sweet SugarBowl, but more support, including Hootcake and Puddingcess' Xyz form quickly made them a force to be reckoned with.
* Clan Malkavian from ''TabletopGame/VampireTheMasquerade'' is one and all incurably insane in some form or another. Some insanities may be "harmless," but the nutjobs are still vampires with all the inhuman strength and resilience that entails. If the guy babbling in the corner thinks you're interrupting the conversation with the voices in his head, they might convince him to tear your arms out and beat you to death with the wet ends. Oh, and one of their clan skills, the one that scares the hell out of other clans, is to [[MindRape "share" their madness with you]] if they feel like doing so, which makes the aforementioned death look preferable.
* Princesses of Spades from ''TabletopGame/PrincessTheHopeful'' have an ideal based on [[CrazyEnoughToWork outside the box thinking]] and [[FunPersonified spreading humor]], which has resulted in them gaining a reputation as lazy and immature pranksters. The crossover section of the game's wiki, however, mentions that some of them managed to con some of the ''[[TabletopGame/ChangelingTheLost True Fae]]'' into leaving the physical world forever.

[[folder:Video Games]]
* Maria Renard from ''VideoGame/CastlevaniaRondoOfBlood''. Oh what's that? Silly little 12-year-old who attacks using animals and heals herself with desserts? You must've missed the part where she can cheese the entire game and her power ''surpasses that of the Belmont clan.'' In a subversion, when she [[VideoGame/CastlevaniaSymphonyOfTheNight grows up]] she has enough power and skill to fight one-on-one with ''Alucard''.
* Henry from ''VideoGame/FireEmblemAwakening'' is this trope taken to its logical conclusion.
--> “Oh, don't let all the joking around fool ya— I've got kind of a thing for killing.”
* Florian from ''VideoGame/OverlordII'' is a bumbling, useless buffoon whose entire purpose appears to be to embarrass the elven race, right up until [[spoiler:it's revealed that he is actually the ''BigBad'' and built ''TheEmpire'' purely so he could transform himself into a god]]. He also happens to be the one who [[spoiler:triggered the magical disaster that turned everyone against magic in the first place]].
* Demyx from ''VideoGame/KingdomHeartsII'' is a great example. The first time you run into him, on Hades' lair, he is ''running away'' from him. Then, during the battle at Hollow Bastion, you have to fight him. Pushover, right? [[ThatOneBoss No]].
** To an extent, Axel, for those who hadn't played Chain of Memories. At first, he's just a PunchClockVillain who wants to grab Roxas and go home. Then [[ATasteOfPower you fight him as Roxas]]. Somehow, you never really forget that moment whenever you deal with Axel afterwards.
* ''Franchise/SonicTheHedgehog'' has Dr. Eggman. The patron saint of HoistByHisOwnPetard, he even ends ''VideoGame/SonicAdventure2'' on surprisingly ''amicable'' terms with the heroic members of the cast. [[IneffectualSympatheticVillain Considering how useless he seems to be, you almost start to feel sorry for him.]] And then you turn around and take a look at his track record. His original shtick of sealing animals inside his robot minions, either to provide power or AI or just plain ForTheEvulz (or some combination of these reasons) already catapults him far past the MoralEventHorizon, and has demonstrated enough OffscreenVillainDarkMatter to construct his very own Death Star-esque Doomsday Machine [[note]]which took Sonic 2-3 games to stop... after which Eggman went and built a second one[[/note]], as well as ''two'' {{Airborne Aircraft Carrier}}s ''in the same game.'' Consider also that ''VideoGame/SonicUnleashed'' starts off with Sonic tearing his way through Eggman's space fleet. Let's read that again: ''Eggman's space fleet''. It's not that Eggman ''sucks'' as a villain; it's that Sonic is just ''that'' good (that, and Eggman has an unfortunate habit of trying to harness the power of {{Eldritch Abomination}}s [[EvilIsNotAToy that are far beyond his control]]). And even then, he [[VideoGame/SonicGenerations eventually gets complete control of one]]!
** Dr. Eggman in ''VideoGame/SonicAdventure2'' starts off the plot by '''''personally''''' destroying a big chunk of a top secret military installation and hacking the computer security system surrounding the SealedEvilInACan. And the first thing he did after getting the ARK and the Chaos Emeralds was ''blow up half the moon'' and give the entire world a 24 hour "surrender-or-die" demand. Eggman is over confident, but his track record kind of warrants it.
** The aforementioned ''VideoGame/SonicUnleashed'' opening shows what happens when anyone -''Sonic'' included- underestimates Eggman, as it ended with him ''nullifying [[SuperMode Super Sonic]] and'' '''''breaking the Earth in pieces'''''.
** The ending of ''VideoGame/SonicChronicles''. Eggman doesn't go with the rest of the gang to stop Ix, claiming he needs to operate some groundside machine to let the others through. [[spoiler:Thanks to the [[YearInsideHourOutside differential time flow inside Ix's prison]], by the time Sonic et al get out, Eggman's rebuilt Eggmanland and may well have taken over the world.]]
** And then there's ''VideoGame/SonicColors''. Not only was he [[spoiler:the BigBad for the entirety of the game,]] but had it not been for a [[spoiler:broken piece of a robot damaging a vital component of his latest weapon]], he would've succeeded in his ultimate plan to [[spoiler:mind-control the entire population of Earth ''with Sonic and Tails none the wiser''.]]
*** Eggman had also managed to enslave three planets and an inhabited AsteroidThicket, as well as build the largest space fleet seen yet, completely under Sonic's nose, and covered much of the land on all of the planets and asteroids with his own metal facilities. He would've completely snuffed Planet Wisp of life as well had Sonic not caught on in time, and he may have succeeded with Sweet Mountain.
*** Really, Colors ''would'' have ended up as a ''victory'' for Eggman if it weren't for one simple fact: The hero was actually being proactive rather than atypically ''reactive''. Rather than wait for the villain to begin his rampage, the hero decided to investigate his machinations without any reason other than ''he is an irredeemable villain!''
* Porky Minch from ''VideoGame/EarthBound'' is a cowardly fat kid with a stupid name. By the final act, [[spoiler:he's acting as the herald of a deranged cosmic entity.]]
* The comic relief character in any Creator/BioWare game usually doesn't appear harmless per se, but he/she/it is usually one of the scariest people on your team.
** ''Videogame/NeverwinterNights'' was one of the first, bringing Deekin Scalesinger with its first expansion. A kobold ''bard'' whose songs are [[SoBadItsGood the wrong kind of good]], and constantly makes some of the silliest, [[LampshadeHanging lampshade-laden]] observations possible. By the third expansion, he's also the best support character you can get, and also an epic-level adventurer who's got enough draconic blood to sprout wings and fiery breath, not to mention [[spoiler:being the only one capable, without your intervention, of telling [[CompellingVoice an archdevil]] to [[DidYouJustFlipOffCthulhu go screw himself]] when asked to betray you]].
** ''VideoGame/KnightsOfTheOldRepublic'': [[HeroicComedicSociopath HK-47]] isn't the most effective combatant on your team, but he's [[spoiler:an assassin droid tailor-built by the greatest Sith Lord in recent memory]] and has a very impressive kill count.
** ''VideoGame/JadeEmpire'': The prime source of comic relief is [[BoisterousBruiser Black]] [[DrunkenMaster Whirlwind]]. He's half again as tall as anyone else on your team, he's got more chest hair than every other person in the game combined, and he dual-wields axes that look like the main character might have trouble lifting one.
*** Also, you can ask him about his past, and be regaled with cheerful and silly stories that prove beyond the shadow of a doubt that he's a terrifying sociopath who is capable of killing anyone for any reason, sees nothing wrong with this, and should not be allowed to be anywhere near innocent people.
** ''VideoGame/DragonAgeII'': [[TheIngenue Merrill's]] social unawareness and clumsiness form a major portion of the humor in the game. She's also a [[BloodMagic blood mage]] with no spells other than those designed to inflict very painful deaths.
** ''Franchise/MassEffect'' trilogy: Jeff "Joker" Moreau is the snarktastic guy who flies the ship, and [[DisabledSnarker would snap in half if you picked him up and shook him hard]]. [[spoiler:He's the guy who fired the shot that killed Sovereign.]] By the third game, he's considered the best pilot in the Systems Alliance, and possibly all of Council space. By a significant margin, at that.
** ''VideoGame/MassEffect2'': Mordin Solus is an unintimidating salarian [[DeadlyDoctor doctor]] who sings Creator/GilbertAndSullivan and participates in children's shows about science. He also [[GlassCannon has purely offensive combat powers]], [[RetiredBadass used to be part of the salarian Special Tasks Group]] (his outfit is a lab coat worn over a commando uniform), and once killed a krogan by stabbing him (or possibly her) in the face with a pitchfork.
** The Volus in ''VideoGame/MassEffect3'' multiplayer are 3-foot tall mole men with an obsession with cash, and while they can't exactly take on a 10-foot tall mech by beating it with its face like a krogan can, they have a lot of tech and biotic powers that manage to turn enemy troopers into so many red smears.
*** Now you can add the [[PowerFist Batarian Gauntlet]] to their equipment. With it, they can [[GroinAttack punch their enemies in the nuts]] so hard it causes their [[YourHeadASplode heads to explode]]. [[labelnote:Explanation]]Killing an infantry-level opponent with the Batarian Gauntlet Heavy melee causes their heads to splatter. However, this effect happens on every species, even when you're playing a volus, who are waist-high at most.[[/labelnote]]
* Creator/{{Bioware}} loves this trope so much that in ''VideoGame/DragonAgeII'', the protagonist can be played with this personality. Snarky!Hawke frequently using BuffySpeak and ObfuscatingStupidity to lure their opponents into a false sense of security that they can't ''possibly'' be that dangerous, right? In reality, s/he frequently shows him/herself to be arguably the most intelligent of the three possible personalities. A good example would be when the party runs into a group of slavers.
-->'''Slaver''': Why, look here boys, ''Volunteers''! Clap 'em in irons and let's see what the Tavinters will pay for them.\\
'''Hawke''': I'd make a terrible slave. I ''talk'' too much.\\
[suddenly draws knife and puts it to the leader's throat before the bastard even has time to blink]\\
'''Hawke''': ...''And, I do '''That'''''.
** During the ''Mark of the Assassin DLC'', during their heist of Duke Prosper's vault, to distract a guard, Snarky!Hawke pretends to suffer an allergic reaction to a bee attack, falling to their knees as dramatic music plays;
-->'''Hawke:''' If I die... tell the world... [[LargeHam I DIED AT CHATEAU HAINE!]]
* ''VideoGame/YandereSimulator'' has the Photography Club, a group of easy-going students who like to joke and pal around...until the school's atmosphere drops to critical levels. Then they become [[LethalJokeCharacter the most dangerous obstacles in the game]], patrolling the school halls in search of the murderer. If they catch you in the act, they'll take a picture and have it sent straight to the cops, [[NonStandardGameOver immediately robbing you of any chance to win Senpai's heart]].
* ''VideoGame/MegaManClassic'' has Dr. Wily who, like Robotnik, loses to a blue guy on a regular basis, but at the same time is a brilliant scientist capable of creating robots with great powers. His greatest creation, [[VideoGame/MegaManZero Zero]], even outlasts Dr. Light's last creation, [[VideoGame/MegaManX X]], and saves all of humanity (though X was active for much longer).
** Wily is dead and buried but his legacy has yet to fade from the series. TheVirus he made with Zero was the origin of [[BigBad Sigma]], and was adapted to make the [[ApocalypseMaiden Dark Elf]].
** His ''[[VideoGame/MegaManBattleNetwork Battle Network]]'' counterpart never stops being a credible threat; every time he's stopped, he's minutes from causing TheEndOfTheWorldAsWeKnowIt.
* ''Franchise/SuperMarioBros'':
** Bowser is often portrayed comically and sometimes Mario will indeed be GoKartingWithBowser or challenging him to other games, but it's clear that he would probably succeed in taking over the world if Mario and Luigi and allies didn't keep thwarting him.
** Mario himself. He's VERY happy-go-lucky, doesn't think twice about GoKartingWithBowser, and is sometimes a straight-up {{Cloudcuckoolander}} due to his overall lack of consistent traits. He's also incredibly strong and very nearly never loses a fight, even if his opponent has an unfair advantage.
** Fawful in the ''VideoGame/MarioAndLuigi'' series. Oh he may be funny with his similes and engrish and funny comments... but he manages to conquer the entire kingdom/world unresisted, mind controls pretty much the entire population and unleashes a monster that wants to destroy reality. He's especially this in ''VideoGame/MarioAndLuigiBowsersInsideStory'', where he gets promoted from TheDragon in the form of a villain's sidekick to the BigBad and driver of the entire storyline.
** ''Videogame/LuigisMansionDarkMoon'' has put King Boo here, going from a [[DeadpanSnarker snarky]], sympathetic WellIntentionedExtremist to an insane, [[TheUnfettered unfettered]] sociopath with a vindictive streak ten miles wide who nearly ''[[spoiler: destroys the universe]]'' in a mad bid for revenge.
** All the villains of ''VideoGame/SuperPaperMario'' are pretty silly, especially [[VillainousHarlequin Dimentio]]. [[spoiler: They plan to destroy the multiverse, and ''succeed in destroying at least one universe''. And Dimentio turns out to be TheStarscream...]]
* The original Silly Villain was Garland "I will knock you all down!" from ''VideoGame/FinalFantasyI''. Who knew [[spoiler:that the very first boss you fight would wind up being the final boss, Chaos, in a ''huge'' EvilPlan]]?
* Kefka Palazzo of ''VideoGame/FinalFantasyVI''. Over the course of the game he goes from a [[LaughingMad cackling]] [[AxCrazy nutjob]] in [[MonsterClown clown makeup]], with fairly unremarkable combat abilities, to a PhysicalGod (but still a cackling nutjob in clown makeup, with the exception of the final boss fight).
** This carried over to the ''VideoGame/DissidiaFinalFantasy'' games. Yes, he's the Chaos Warrior most likely to crack a joke about [[ToiletHumour farting]], and has a walk silly enough to get him into the [[Series/MontyPythonsFlyingCircus Ministry]], but, when the situation calls for it, he's incredibly conniving and dangerous. In fact, it even turns out that '''''he's''''' the one who [[spoiler:jumpstarted the rivalry between Cloud and Sephiroth]]!
* And let's not leave out Gilgamesh, of ''VideoGame/FinalFantasyV''. Every times he opens his mouth, it's for either a badass boast, a biting insult, or some random pop culture reference. Sometimes all at once. And, despite being both a complete nutter and the source of most of the game's funniest moments, he's still able to level entire armies singlehandedly, survive onslaughts from ancient sealed monsters, and oneshot an endgame boss. And this is ''before'' he started hopping TheMultiverse.
* [[BigBad Purge]], from ''VideoGame/SpaceChannel5'' (part 2). At first, he seems just as goofy and [[CampStraight camp]] as [[WidgetSeries everyone else in the game]]. He constantly {{giggl|ingVillain}}es, pelvic thrusts, and dons a ''sparkly purple disco suit'' for your penultimate dance-off. With Michael Jackson and a giant laser at your side, all it should take is one attack to finish him off! ... "[[KaizoTrap Tch]], [[DisneyDeath yeah]] [[HopelessBossFight right]]!"
* Dr. Mundo from ''VideoGame/LeagueOfLegends''. He's huge, he's purple, he talks in the third person, he has a silly voice, and he has silly dialogue. He is also a serial killer who regularly engages in human experimentation.
* Kaos, the BigBad of ''VideoGame/{{Skylanders}}'', is an {{Expy}} of ''WesternAnimation/InvaderZim''[[note]]right down to [[Creator/RichardStevenHorvitz the voice]][[/note]]. His first battle with the heroes ended with the Core of Light, the only thing keeping Skylands safe from the forces of Darkness, destroyed along with most of their HQ and ''all'' the Skylanders plus their BigGood MIA.
* Ghirahim, the BigBad of ''VideoGame/TheLegendOfZeldaSkywardSword'', could be considered an inversion, as the "beware" side was seen first when he mentions that he created the tornado to capture Zelda. He displays his silliness in his campy lines and hand gestures after Link gets to meet him.
* ''VideoGame/TheElderScrollsVSkyrim'' has Cicero, the mad jester and Keeper of the Night Mother. At first his wheezing giggle, eccentric personality and high-pitched voice are merely obnoxious. [[spoiler:Then he attacks Astrid, wounds Veezara and disappears to the empty Dawnstar Sanctuary, after wounding Arnbjorn (a werewolf) in hot pursuit. He will continue to taunt the player from the shadows of the Sanctuary as the player fights through a legion of Spectral Assassins, though he grows [[VillainousBreakdown increasingly panicky as the player continues to progress]].]]
** We also have this lovely quote from [[MadGod Sheogorath, Daedric Prince of Madness]]:
-->'''Sheogorath:''' Now you. You can call me Ann Marie. But only if you're partial to being flayed alive and having an angry immortal skip rope with your entrails.
** For a long time, the Argonians were largely considered a joke among the fandom. Given their tendencies towards {{Cloudcuckoolander}} and having names like Hides-His-Eyes, Scouts-Many-Marshes and Nine-Toes, it isn't hard to see why. Fans quickly dropped this view in ''Oblivion'' with the reveal that they were the only force in all of Tamriel that were able to hold off the [[HellOnEarth Dremora invasions]], and in fact eventually forced the Dremora to close the gates because ''[[MuggingTheMonster the Argonians were launching invasions into Oblivion]]''. In ''Skyrim'', it's heavily implied that they're one of two nations who could hope to stand against the [[RisingEmpire Aldmeri Dominion]], the other being [[HumansAreWarriors the Redguards of Hammerfell]][[note]]This may largely due to the ineptitude of the Cyrodilic Empire and the political disarray of both High Rock and Skyrim as seen in the [[VideoGame/TheElderScrollsVSkyrim fifth game]][[/note]]. It's very possible that those insane lizard people are ''the'' single most dangerous fighting force ''in all Nirn''. This evolution is ostensibly justified in-universe by the fact the "Hist", the sentient trees of Argonia/"The Black Marsh", have been slowly strengthening generations of Argonians, especially after the Oblivion Crisis, to make them stronger and stronger, to the point that the Argonians are pushing into Morrowind after being under the thumb of the Dunmer houses for so long.
* Jasper Batt Jr. from ''VideoGame/NoMoreHeroes2DesperateStruggle''. Setting aside the fact that [[spoiler: he used his pizza empire to climb to the top of the UAA and was the one who ordered the hit on Bishop]], most players will think, "He's just a scrawny, bucked-tooth nerd with a hilariously bad sense of fashion. How bad can he be?" Then they actually fight the guy and he turns out to be one of the most irritating bosses in video game history.
* A heroic example: Tyrell from ''VideoGame/GoldenSunDarkDawn'' is blatantly set up as the bumbling sidekick. He starts the game by getting into trouble over his head and breaking valuable equipment, he makes fun of the bad guys' names, he identifies an extinct settlement as such by the [[BigEater lack of food]], and he [[LetsGetDangerous flips out and attempts]] a NoHoldsBarredBeatdown on [[TheEvilGenius Arcanus]]. Wait, what?
* Sho Minamimoto of ''VideoGame/TheWorldEndsWithYou'' seems not such a big deal when he first appears. He's just some annoying Reaper who screams in a megaphone and makes junk sculptures while [[MadMathematician talking in math metaphors]]. Even when you first fight him, he's not too bad. Oh, and he [[spoiler:unleashed an army of nearly indestructible monsters on the UG and managed to come back to life in a new body that ends up being one of the hardest optional bosses in the game]]. Also, [[spoiler:'''HE'S TRYING TO KILL GOD AND ALMOST DID IT TWICE''']].
** There's also Joshua, a smug, spoilt 15 year old Jerkass who becomes your partner in the second week. He's pretty weak for a while, with powers that include [[ImprobableWeaponUser dropping pianos from the sky with his cellphone,]] constantly teases (and occasionally [[AmbiguouslyGay flirts with]]) Neku, is the only male character who can [[AgentPeacock wear girl's clothing]] the moment he becomes playable, and is the only person in the entire game who can use a mobile, apparently because he didn't get the message about them being banned. Level him up enough and he becomes the most powerful partner of them all, reigning huge beams of holy light down on to enemies with his cellphone rather than pianos. [[spoiler: He's also the BigBad. And God.]]
* Steven Heck of ''VideoGame/AlphaProtocol'' is a very silly individual: he rambles on about conspiracy theories involving the Federal Reserve having UsefulNotes/WilliamMcKinley assassinated and the government tinkering with the price of strawberries to control people's minds, gives {{Word Salad Title}}s to every covert operation that occurs in Taipei, is willing to use the JackBauerInterrogationTechnique on someone to get him to remember where he put his car keys, and takes Time Cube quotes seriously. He is also, however, one of the most dangerous men alive, capable of wiping out entire rooms full of soldiers and elite intelligence operatives singlehanded. His method of dealing with the Chinese Secret Police agents who have Mike Thorton pinned down in the Taipei subway perfectly captures Heck's mix of silly and lethal:
-->"During the pursuit, Steven Heck (at Agent Thorton's request) arrived to offer emergency backup. Said backup came in the form of Heck crudely mounting a minigun to a subway car and firing wildly at Chinese secret police officers as his train passed the platform."
* The modrons in ''VideoGame/PlanescapeTorment'' are practically comic relief, behaving like socially awkward and poorly programmed robots that are very easy to kill. Then you get hit by the [[PlasmaCannon Mechanus Cannon]] spell for the first time - the first spell to get its own cutscene - and they cease to be as funny: https://www.youtube.com/watch?v=XUjvJP1gOMc.
* The final ''VideoGame/TeamFortress2'' "Meet the Team" video reveals something very disturbing about the {{Pyro|maniac}}: that he, she, or it ([[AmbiguousGender take your guess]]) doesn't see the world the same way everyone else does. The Pyro sees a rainbow blower, a bubbler; and lollipops, everyone else sees searing flames, explosive flares, and a mean fire axe. Pyro cheers for joy [[DreamLand in a psychedelic dream world]]; others see Pyro cheer in sadistic glee, a burning town for a backdrop. In a way, it makes the Pyro even scarier.
* ''VideoGame/StarControl'' has its fair share of ridiculous aliens who are much more dangerous than they seem.
** The Spathi are these ridiculous clam creatures who live in perpetual fear of virtually everything. They also advanced from the Bronze Age into the Atomic Age in under a century in response to the arrival of the Evil Ones (they wanted to escape to the Moon, you see), and a Spathi Eluder is one of the best ships in the game as long as you fight like a Spathi (AKA running away the entire time (they're extra-fast), blindly firing homing missiles behind you, while the decoy crew compartments soak up all the damage). A human veteran of a war against them compared them to "mobile, cowardly clams armed with howitzers".
** Orz are weird ''things'' that look like floating parrot faces, with a StarfishLanguage so alien your translator needs to make guesses, which leads to insanely strange conversations about *parties* and *campers*. They're also one of the few races confirmed to have entirely wiped out another, and [[spoiler: are, as a whole, just one creature; each individual Orz is just one of its *fingers* in this dimension]].
** Pkunk are essentially a pacifistic offshoot of a species of proud warriors, that devolved into space hippies with a fondness for word salad metaphors, visions about mundane stuff and arguing with the supposed spirits giving them their visions. Some of their beliefs are very real, however, including the one about reincarnation; this manifests in their ships, which are already decent and charge their power by having their crew ''insult you'', can spontaneously resurrect themselves after getting destroyed. Not a good idea to get on their bad side.
** Thraddash would seem like ineffective brutes; they themselves tell you they're on their 19th attempt at having a civilization (they nuked themselves to hell 18 times already), and they lose more ships to infighting than to the enemy. However, their Torch ships have ''vicious'' afterburners that make them impossible to even touch if properly controlled, and their bullets, while weak, cannot be blocked by anything. Hence, a competent pilot can kill ''anything'' through DeathOfAThousandCuts and be untouchable in return.
** The Utwig are essentially space emos, due to entering a collective depression after breaking their beloved artifact (the Ultron). Even before that, they were silly, what with having a culture revolving around expressing ''every'' emotion through a mask, including those involving bodily excretions (they burned them all aside from their mask of ultimate shame to atone). They're also one of the most formidable races out there, having ships with absorbing DeflectorShields that make them almost indestructible if properly used. This is even shown in-game, if you fix the Ultron; they join the war, and proceed to hold off the Kor-Ah (your main antagonists) for an entire ''year'' where most other races couldn't do anything other than get wrecked.
* The Goof-off/Jester/Gadabout class of ''VideoGame/DragonQuestIII'' is just that - they will often disregard your commands and do something random and useless. Plus, they have all around low stats so they do very little even when they follow orders. Then they get a free class change into a [[MagicKnight Sage]], which is one of the best classes in the game.
* Solt and Peppor of ''VideoGame/ChronoCross'' are the QuirkyMinibossSquad, HeKnowsAboutTimedHits, and GoldfishPoopGang all rolled up into two rather silly and bumbling brothers. That is until [[spoiler: they call out their superior, Karsh, for the murder of Dario, upon which they drop all the silliness and become a ''genuinely challenging boss fight'' dropping their general stupidness and using potent elemental attacks]].
* Veigar, from ''VideoGame/LeagueOfLegends'', is generally seen as ridiculous in large part thanks to being short, having a very high pitched voice, and then there's the whole scheme to steal Bandle City's monument-thing using helium balloons and horseshoes. He also happens to have one of the highest burst damage potentials in the game, as well as being one of only two characters that has a potentially infinite offensive scaling.
* The ''Franchise/TalesSeries'' loves to do this with its [[TheMole mole]] characters. There's usually one traitor per game, and while they mix it up enough to keep you guessing, it's often the biggest idiots who screw you over the hardest:
** ''VideoGame/TalesOfSymphonia'' has [[spoiler: Zelos, team ButtMonkey and TheCasanova, turn on you last second and hand Colette over to the BigBad. In a way, this scene can double as a Beware The Silly Ones for the villains; they, too, underestimate Zelos, and in certain paths that enables him to [[BigDamnHeroes save the entire party]] and rejoin you with a key plot item]].
** ''VideoGame/TalesOfVesperia'' has [[spoiler: Raven, who acts like a grown-up and less flirtatiously successful version of Zelos. He, too, hands your female protagonist over to the BigBad, and then reveals himself to be Captain Schwann, and ''then'' promptly kicks your ass so hard he's ThatOneBoss for a lot of people. Like Zelos, the BigBad makes the same mistake, and Raven returns to you later, despite the fact that the villain could literally kill him at any time]].
** ''VideoGame/TalesOfGraces'' has a temporally inverted version of this. The bewaring comes first and the silly second. [[BewareTheNiceOnes Young Richard]] is relatively quiet and melancholy, but then he gets [[spoiler: possessed by the BigBad Lambda]] and goes on the rampage. You spend most of the main plot bewaring of Richard and his terrifying winged form and his VoiceOfTheLegion...and then he gets better, and Richard in the future arc is a {{Troll}} and a completely incomparable LargeHam goofball with his own line of fruit snacks.
* ''VideoGame/KidIcarusUprising'' is an AffectionateParody of Greek mythology with NoFourthWall and boasts a colorful cast of wacky characters. Characters who, despite appearances, should not be taken lightly.
** There's [[TheHero Pit]], the titular hero himself. He's a flightless angel who ''loves'' to banter and joke, even BreakingTheFourthWall. Most of the humor in the game comes [[ButtMonkey at]] [[CosmicPlaything his]] [[TheChewToy expense]]. But this is a guy who can [[OneManArmy take on entire armies at once (sometimes multiple armies at the same time)]] as well as [[DidYouJustPunchOutCthulhu take on several gods]] with nothing more than the weapons he wields..
** Palutena, the Goddess of Light and the BigGood of the series is more of a GenkiGirl than a goddess, a certified DeadpanSnarker who trolls Pit every opportunity she gets. But if the situation calls for it, she's just as capable of kicking ass. In chapter 3, if Pit takes too long to defeat Hewdraw, she'll summon the [[DeathFromAbove Sacred Goddess Clobberlaser]] to [[OneHitKill oneshot it]]. [[spoiler: She also serves as the boss of Chapter 20]], showing just how powerful she can be when she decides to cut loose.
** [[spoiler: [[BigBad Hades]] is essentially this game's Creator/TimCurry. His [[LargeHam flamboyant]], [[DeadpanSnarker snarky]] and sometimes [[CasanovaWannabe flirtatious]] attitude makes it hard to take him seriously. But this ''is'' the God of the Underworld and is as every bit as powerful as a PhysicalGod should be as his fights with Pit will attest. This is a guy who can and sometimes will destroy entire countries for fun and is cunning enough to get entire nations to fight each other over a nonexistent item.]]
** [[MonsterClown Thanatos]], the God of Death is basically an {{Expy}} of TheMadHatter. He's childish, goofy, and a bigger ButtMonkey than Pit himself. But he is likewise far from harmless. This is especially in the anime short ''Thanatos Rising'' [[spoiler: where he effortlessly defeats a human army and takes control of their Trojan horse tanks. And he nearly kills Pit soon after.]]
** [[NatureSpirit Viridi]], the Goddess Of Nature, is one of the snarkiest characters in the game and looks ([[PsychopathicManchild and acts]]), like an eight-year-old brat. But as her debut chapter shows, her capacity for destruction is deadly real thanks to her Reset Bombs.
** [[ShockAndAwe Phosphora]], Viridi's [[TheDragon Dragon]], is a laid-back and flirtatious ValleyGirl... one who has [[WeatherManipulation the power of the storm]] at her disposal and like Pit, is just as capable of taking on gods. [[spoiler:Thanatos learns this the hard way.]]
** [[ThePowerOfTheSun Pyrrhon]], the self-proclaimed Sun God, is the biggest Ham in the game and the epitome of the over-the-top superhero parody. His loud, boisterous attitude makes it hard for anyone to take him seriously... [[spoiler: At least until it's revealed that he was using everyone's help to take control of the Aurum Brain and become the strongest god in existence. [[BrainwashedAndCrazy But then his plan backfires a few minutes later.]]]]
* It'd be hard to list all the ''VideoGame/{{Touhou}}'' characters who ''don't'' qualify as this, due to their wacky plots and hijinks, and the dangerous (or potentially-dangerous) powers they're capable of using.
* ''Videogame/DawnOfWar II: Retribution'': While Warhammer 40K orks are plenty silly in general while also being plenty deadly, the ones followed in the Ork campaign take both these traits further than usual. The silly? They treat a gigantic war machine like one'd treat a puppy (complete with ''walks''), have a stealth specialist that once tried to hide in lava, and their leader is a space pirate, complete with ''hat and attire'', among many moments of gleeful lampshading and general black humor. The dangerous? This band of lunatics easily stomps several recently-defected chaos bases, take down the Eldar campaign's own hero, [[spoiler: finish off an entire craftworld, manage to track down a Space Marine chaptermaster through logic alone (where even the Eldar failed at first, mind you), beat the living ''hell'' out of him when he had ascended to greater Daemon only ''minutes'' ago, and blow his head off with a captured asteroid]], and, to top off these and many other acts of wanton looting and burning, depending on the optional missions taken, they [[spoiler:simply leave on their new ship, looking for more planets to loot. The new ship being a gigantic dreadnought that had been stuck in [[HyperspaceIsAScaryPlace the Warp]] for so long it was basically the Film/EventHorizon's bigger brother. Oh, and their leader also mugged Inquisitor Adrastia for her NiceHat]].
* The Boss from ''Franchise/SaintsRow''. Has been known to do such things as streak, vehicle surf, [[BreadEggsBreadedEggs vehicle surf naked]], spray feces on buildings from a stolen septic truck, dress up as a sex doll, dress up as a toilet, wield a dildo bat and fart bombs, get electrocuted by licking a flagpole during a thunderstorm, auction themself off as a sex slave, star in a godawful B movie, sing along very badly to 80s songs, and participate in amateur night at a strip club. Also, has killed more people than the average war, became president of the United States, has a suit of PoweredArmor and a time machine, is currently God-Emperor of the universe, and was handpicked by Satan to be his successor until two of their subordinates caused enough trouble to get them permanently banned from Hell.
* If you choose Male Voice 8 for him, the Future Warrior from ''VideoGame/DragonBallXenoverse'' can be this. But hey, that's [[WebVideo/DragonBallZAbridged Abridged Nappa]]'s voice you're using, so [[JustifiedTrope what did you expected?]]
** You can also create a male Majin character, which much like his ancestor is fat and goofy-looking while also being able to take on some of the most powerful individuals in the series.
* ''VideoGame/FalloutNewVegas'':
** Caesar's Legion. Look past their constant misuse of Latin and their ridiculous costumes (sports gear kitbashed to resemble Roman legionary armour) and you'll see nothing more than a pack of misogynistic slavers and cruel sadists who possess the cunning, ruthlessness and numbers to pose a grave threat to the people of the Mojave and, unless someone stops them there, potentially far beyond.
** The entire Think Tank, along with Dr. Mobius. They're severely displaced in both time and general common sense, they frequently screw up their own experiments or just take extremely stupid directions to start with, and are so disconnected from reality they think your fingers are penises. Generally, they mix their MadScientist-tier intelligence with general stupidity brought on from several factors to hilarious effect, with each member bringing their own quirk to add to it. And then you realize they want your help to escape the Big Empty, and just what they intend to do with the Mojave Wasteland. An ending cut from the game lets you know that, had they run rampant, they'd have turned the entire Wasteland into their own personal laboratory, and would've killed millions in experiments both cruel and idiotic. Even their previous exploits show some of this danger: Mobius alone was capable of building a giant robot scorpion that'd easily trample a small army. Borous made [[DemonicSpiders Cazadores]] and Nightstalkers, more or less because he just wanted to. The five working in tandem subdued ''[[TheRival Ulysses]]''. And every single thing you find in the Big Empty that tries to kill you? They made all of them.
* ''VideoGame/{{Undertale}}'':
** Sans is introduced as a terrifying presence stalking you through the woods...up until he lets loose with a ridiculous "whoopee cushion in the hand" gag. From that point on, he presents himself as a lazy, laid-back comic relief character who'd rather hang out with you at the local restaurant than actually do his job. As he eventually confesses, he even promised [[spoiler: Toriel]] he'd watch over and protect you...[[spoiler:and if it hadn't been for that promise, [[MoodWhiplash he would have killed you when he first laid eyes on you.]]]] It's implied he knows ''far'' more about the situation than he lets on, and even Flowey, in certain lines, admits he's terrified of Sans, and considers him the most dangerous monster in the Underground. [[spoiler:If you kill absolutely everyone you run across, you find out why. ''Painfully''. Sans will decide that he can't ignore such a threat, and fight you himself. He is, by a wide margin, the most difficult challenge in the game.]]
** His brother Papyrus also fits the trope, although on a lesser scale. When introduced, he's a bumbler whose unrelenting naivete and obsessions with puzzles and spaghetti hinder his goal of joining the Royal Guard. He repeatedly tries to capture you with tricks and traps throughout Snowdin, with no success. Even when he decides to fight you himself, his attacks are inaccurate, he's easily distracted by flirting, and his supposedly legendary "Blue Attack" is totally ineffective...[[spoiler: until [[UnexpectedGameplayChange gravity kicks in]]. What follows, although not on the level of most of the late-game fights, is one of the game's first real challenges]]. Indeed, if you compare stats, Papyrus is, going by raw strength, the third most powerful monster in the Underground (and yes, that means he's stronger than Undyne). It is often theorized that his battle would be even harder if Papyrus wasn't [[WillfullyWeak too nice to want to hurt you]]. This is corroborated by his dialogue if you spare him on a previously No Mercy playthrough, which strongly insinuates that he can use [[spoiler:[[WaveMotionGun Gaster Blasters]]]].
* In ''VideoGame/{{Runescape}}'', Dimwit the Goblin, AKA Yelps, is a scrawny, wannabe game-show host who lives up to both of his names. His sole purpose in life was to operate a Series/WheelOfFortune {{Expy}} and to get punched in the face by a crude machine as part of said minigame, and he reveled in this. However, his voice when he cheered players on was apparently so annoying that 42% of the playerbase voted to have him killed off. No one expected this to occur in the form of a boss fight wherein the tiny goblinoid transformed into a spinning, teleporting dervish capable of dealing massive, rapid damage, summoning groups of high-levelled minions, becoming temporarily invincible, and sporting a health bar exceeding that of the literal mother of all dragons.
** Sliske looks and acts like a hunchbacked snarky clown when he's not [[DealWithTheDevil double-dealing]] or outright forcibly controlling mortals into becoming his [[TragicMonster undead thralls]], [[spoiler: murdering Guthix]], [[spoiler: kidnapping Death and the Dragonkin to bring about a new God War]], or [[spoiler: urging you to cripple Zaros, ''his own patron god'']]. Possibly the worst part is that he manages to be [[BlackComedy darkly hilarious]] even while committing the aforementioned atrocities.
* In ''VideoGame/TalesOfMajEyal'', the ''Embers of Rage'' expansion includes Nektosh the One-Horned, an [[NinjaPirateZombieRobot undead minotaur who thinks he's part-unicorn]] on account of his two horns twisting together into a spiral. He's fought about a third of the way through the campaign, and has given at least one hammy speech that would put Skeletor to shame. The magical beam he can shoot from his "horn" is ''the [[WaveMotionGun most powerful attack]] in '''the entire game.''''' (It's [[SuckingInLines easy to see]] where he's pointing it and get out of the way, but still...) [[spoiler:This is because he has [[LostTechnology an ancient Sher'Tul wand]] stuck in his "horn" - it's running out of energy, so his last few blasts won't be as impressive as the first few, and eventually he runs out of ammunition entirely.]]
* Franchise/GreenLantern from ''[[VideoGame/LegoAdaptationGame The LEGO Movie: The Game]]'', like his ''[[Film/TheLegoMovie movie counterpart]]'' is annoying, dopey, and just a [[HoYay little too interested]] in Franchise/{{Superman}}. In the movie he's only there as ComicRelief and to take a beating, but in the game he's not only the only character with flight and a projectile-type attack, but is also the only character capable of moving green bricks. Once he's unlocked there's little reason to use any other character unless you need their unique abilities for a specific task.
* Sheath from ''[[VideoGame/ProjectXZone Project X Zone 2]]'' speaks in broken English and acts bubbly and air-headed. While she's a fairly manageable enemy normally, in the penultimate stage, [[spoiler: she's piloting the 9-9 MiniMecha, which has a massive range, is mobile, and can hit for tons of damage]]. Underestimate her and she'll do to you what she does to the Japanese language.
* In ''VideoGame/{{Persona 5}}'', the Shadow Selves your party targets are often ridiculous looking, but they rule their own Palace and serve as major {{Boss Battle}}s. These include: A giant headed pink demon wearing nothing but a crown, cape and underpants; a gray haired man dressed like a JidaiGeki lord in a tacky golden kimono, too much white face paint, and giant fake eyebrows; a purple fly man with a mustache, bad comb-over and white tuxedo; and a BlackKnight wearing the evil version of the hero costumes from a children's SuperSentai TV ShowWithinAShow.
* While most players know that BadassAdorable creatures run rampant in ''{{Franchise/Pokemon}}'', there are still a few 'Mons that are hard to take seriously on the surface. For example, Vanilluxe; the double-scoop that tops off a line of smiling ice cream cones. Goofy-looking, sure, but statistically tied with Lapras as the ''strongest'' non-legendary Ice type. It's got especially good special attack, learns [[OneHitKO Sheer Cold]] naturally, and as of Generation VII it gets [[WeatherManipulation Snow Warning]] as an ability.
** Palossand and to a lesser extent its pre-evolution Sandygast. They are living sandcastles, with a spade still stuck in them. How dangerous can they be, really? Well, they are '''haunted''' living sandcastles, not exactly the most badass object to haunt. And then you find out that Sandygast can MindControl anyone who puts a hand in its mouth to be his slave. Now think, [[WouldHurtAChild who would be most likely to do that?]] And Palossand are able to trap creatures in sand vortexes and LifeDrain them until they straight-up '''die''', their vengeful spirits turning into new Sandygast.

[[folder:Visual Novels]]
* There are quite a few comic-relief characters in the ''Franchise/AceAttorney'' series, several of which have committed crimes.
** Luke Atmey takes the cake. It's rather difficult to take this particular blowhard seriously, [[spoiler:until you learn he was the mastermind behind several thefts thought impossible. In fact, while Atmey is a {{Pride}}ful AttentionWhore, he also qualifies as an InsufferableGenius and even a MagnificentBastard, getting you to have him ''accused of theft'' just so he could use that as an alibi for a murder that happened at the same time--a murder he actually had committed]]!
** ''[[VisualNovel/PhoenixWrightAceAttorneyDualDestinies Dual Destinies]]'' manages to one-up Atmey with Detective Bobby Fulbright. When you first meet him, he comes off as an incompetent buffoon, with his [[LargeHam over-the-top shouting about justice]], but he [[CrouchingMoronHiddenBadass ends up being quite competent when it comes to handling the enraged Prosecutor Blackquill and actually manages to come up with some crucial evidence at just the right moment to save your client in Case 4.]] [[NiceJobBreakingItHero Which directly causes Case 5.]] [[spoiler:This wasn't accidental. The ''real'' Bobby Fulbright died one year prior to when the game takes place. The "Bobby Fulbright" you know throughout the game is in fact the nameless "phantom" directly responsible for several murders, who wanted to frame Athena for his crime. He's a MasterOfDisguise who took on the identity of the dead Detective Fulbright in order to manipulate evidence, as well as to use Fulbright's over-the-top personality to conceal his own ''near-complete lack'' of normal human emotions.]]
** ''[[VisualNovel/AceAttorneyInvestigationsMilesEdgeworth Ace Attorney Investigations 2]]'': The BigBad, a ManipulativeBastard ''par excellence'' who orchestrated every murder in the game, using [[GambitIndex every type of gambit on the index]] in order to get the revenge he had desired ''since childhood''? [[spoiler:He works as an ''animal trainer at the circus''.]] Not only that, [[spoiler:but you meet him in an earlier case ''as a murder suspect that you prove innocent'']]. Even Edgeworth was fooled.
* Akiko in ''VisualNovel/AkatsukiNoGoei'' is incredibly silly and tends to flirt with Kaito despite being his mother's age even if she doesn't look it. However, people who know her well are actually scared of her. For good reason, given that she blackmails Satake [[spoiler:for trying to hide Kaito's past from him]] and even Genzou will not act against her. She even calls him Genzou-kun like he was still a student and gets away with it.
* Haruka from ''VisualNovel/MyHaremHeavenIsYandereHell'' is peppy and energetic and she can get carried away with herself sometimes. Unfortunately, she's clingy and possessive of Yuuya and is also one of the {{Yandere}}s available.

[[folder:Web Comics]]
* Black Mage is TheChewToy of ''WebComic/EightBitTheater'' and spends most of his time stabbing [[MadeOfIron Fighter]] and failing to get into White Mage's pants. A few times, however, he's acquired enough power that he decides he doesn't need his companions. On these occasions, he shows in no uncertain terms that he's not joking about being an OmnicidalManiac, and he has come ''very'' close to wiping out reality. On one occasion, he finally succeeded in murdering the rest of the Light Warriors [[spoiler:only for Sarda to resurrect them just to screw with Black Mage.]]
* Khrima from ''Webcomic/{{Adventurers}}'' spends most of the story as comic relief, since he's [[PokeThePoodle laughably bad at conceiving with evil plans]] and his minions are (for the most part) about as threatening as a wet sock. It's hard to take him seriously as an EvilOverlord, especially when compared to [[KnightOfCerebus Eternion]] later on. Despite all this, he still manages to be a very tough FinalBoss with no less than ''four'' OneWingedAngel forms.
* Marmalade was introduced as a harmless mook in ''Webcomic/DarkLegacyComics'' but when he became self-aware, he became a monster.
* Lord Kyran from ''Webcomic/EmergencyExit'' is usually depicted as both [[http://eecomics.net/EEArchives/?strip_id=143 silly]] and [[http://eecomics.net/EEArchives/?strip_id=779 harmless]] then you get moments like [[http://eecomics.net/EEArchives?strip_id=657 this]] and [[http://eecomics.net/EEArchives/?strip_id=1006 this]].
* The Jaegermonsters known as [[FanNickname da Boyz]] in ''Webcomic/GirlGenius'' are [[AmazingTechnicolorPopulation variously-hued]], apparently dim (except for Dimo, who is often the OnlySaneMan of the trio) FunetikAksent speaking comic relief...until it's time to fight, and then readers are reminded that they are brightly-colored ''MadScience-engineered {{Super Soldier}}s'' who do not just have pointy teeth and sharp nails for decoration.
** Hell, just Jaegers in general. They ''all'' have that accent, all of them like their hats big and shiny, and all of them would joyfully run into a huge, bloody battlefield like a kid would into an amusement park, before tearing up entire squadrons barehanded. Even their generals, who are several centuries old, have no qualms joking around in a skirmish, to the point four of them decided to have a little body-count competition, with one of them spending most of the battle getting the rules straightened out, during an invasion on their hometown. [[CurbstompBattle And they stomped the everloving hell out of the invaders]], with the general that wasted most of the battle winning the competition by way of ''blowing up the airship carrying the entire force''.
* ''Webcomic/{{Homestuck}}'': [[spoiler: Gamzee goes from a goofy, [[TheStoner stoner]] LoveFreak while drugged out on sopor slime to a frighteningly effective [[SlasherMovie Slasher-esque]] [[AxCrazy killer]] when sober.]]
** The [[AffablyEvil Courtyard Droll]] counts too. Despite working for the evil Dersites, he's a {{Cloudcuckoolander}} whose version of torture involves [[FelonyMisdemeanor swapping hats with someone]] - and a terrifyingly effective assassin with a bodycount that includes [[spoiler:both Jade and Jake's dreamself.]] For comparison, Hegemonic Brute, TheBigGuy of the agents, managed to accumulate ''zero'' kills before his [[spoiler:death in both universes]].
** John, Jade and Nepeta also count. With the exception of Gamzee, they are the silliest of the heroes. Nepeta is able to kill large wild animals with her bare hands, John, [[spoiler:upon becoming a wind god, creates a massive tornado which he uses to drill to the centre of a planet to retrieve a massive bomb, In Cascade, he creates lava tornadoes and defeats the largest enemy seen in the game with a single hit, and sometime later becomes the first person to land a hit on Bec Noir, dealing about 1/10th of his health in damage off of one hit]]. When Jade [[spoiler:reaches God Tier, she becomes fused with Bec, making her probably the strongest member of the group]].
* Head Alien of ''Webcomic/ItsWalky'' fame generally comes off as a cartoon villain, constantly dreaming up plans doomed to be easily foiled by the introduction of the heroes, who never passes up the opportunity to show his love for dramatic tension, even when doing so hinders or even cripples his plans. [[XanatosGambit He always managing to further some goal every time he is effortlessly crushed]], and all it takes is a moment of talking before he's got you trapped with a [[BreakThemByTalking Breaking Speech]], eating out of his hand doing exactly what he wants.
** The title character himself counts, considering he spends much of the series as a ManChild. Even if it's [[ObfuscatingStupidity partly an act.]]
* ''Webcomic/TheOrderOfTheStick'':
** Xykon spends much of his time as borderline comic relief: much of his villainy appears to be of the {{card carrying|Villain}} variety, and many of his interactions with his supposed subordinate Redcloak imply that the latter is the far more intelligent of the two. This all obscures the fact that Xykon ''scares the pants'' off of Redcloak; even though he's the high priest of an evil god, Redcloak's goal is equality for goblins, orcs, and other races that are normally just cannon fodder, while Xykon's goal is more or less "TakeOverTheWorld and [[ForTheEvulz inflict as much pain and mayhem as undeadly possible]]".
** Even ''with'' the heroes out to stop him, he's a credible threat to the entire world. They kind of beat him the first time kind of by accident, but since then they've been lucky to get away with their lives when tackling him (and not always so lucky), and that's with him conquering a city and beating its forces at the same time. (With Redcloak's help.)
** The time when he took on the entire roomful of Sapphire Guard makes this even more apparent. He starts out by tossing a super bouncy ball at them, which was inscribed with a Symbol of Insanity that made them kill each other. Xykon got a whole lot less funny all of a sudden. He even commented that he could've just kept to the air and blast all of them. The only reason he had the Sapphire Guard kill each other was because he thought it would be "going the extra mile".
** Xykon's BatmanGambit in ''Recap/StartOfDarkness'': [[spoiler:Xykon tempted Redcloak into killing his brother Right-Eye to protect him]]. The [[BreakThemByTalking Breaking Speech]] that follows speaks for itself.
--->'''Xykon:''' [[spoiler:So therefore, you're just going to continue following me and doing whatever I order you to do. Because as long as you're loyal to me, I'll let you pretend this never happened. We'll just go about our daily business, and you can hide from the horrifying truth of what you've become - namely, a murderer who just killed his baby brother in cold blood. And hey, we can pretend that you don't really have any options about any of the despicable actions I ask you to take here on out rather than acknowledging that, like Right-Eye, you do in fact have a choice. But unlike Right-Eye there, you're too chickenshit to ever make it. You'll obey me forever now, because I give you an excuse for your inexcusable behavior. Now, are you going to stand there and tell me I'm wrong? Didn't think so.]]
** Also, [[QuirkyBard Elan]], as [[SmugSnake Kubota]] found out the hard way
** In the Linear Guild, Thog the half-orc. Because he's a funny, ditzy, childlike blithe spirit, people ([[DracoInLeatherPants readers especially]]) tend to forget that he's a killing machine prone to {{Unstoppable Rage}}s when he gets bored (like, say, if he runs out of ice cream).
-->'''Tarquin:''' It's weird. [[LeaningOnTheFourthWall No matter how many people he kills, people still think he's lovable.]]
** The Monster in the Dark is this in two directions simultaneously. Firstly, it was [[InformedAbility introduced as a terrible monstrosity]] only to turn out to be somewhat dim-witted and quite possibly harmless. Secondly, after spending a long time behaving in a very child-like and friendly manner and doing nothing else, we got a few clues that the [=MitD=] might in fact be an exceptionally powerful (and thus potentially dangerous) creature. Its true nature has yet to be revealed, but from what we know, his very ''lightest'' whack will send you flying through the nearest wall, and a stomp of his creates minor earthquakes, among other mysterious feats. Most recently he joined Xykon, Redcloack, and a new character in clearing out a cave full of monsters. All the others came out visibly damaged - including Xykon! The Monster in the Darkness comes out still carrying his bucket of red paint. As in, he presumably did it all one handed.
* Brian Souballo, from ''Webcomic/OurLittleAdventure''. He is hard to take seriously as the BigBad as he's [[AffablyEvil friendly]] and a bit of a {{Cloudcuckoolander}}. His cheerful demeanor was only ruined once by an old magic teacher he was trying to recruit for the empire. [[http://danielscreations.com/ola/comics/ep0197.html Read about it.]]
* Jareth from ''Webcomic/{{Roommates}}''. Let's see he seems like a {{keet}}, [[DumbBlonde blond]], [[TheTrickster prankster]] with [[FearlessFool questionable level of self-preservation instinct]] who [[ItAmusedMe only wants to have fun]]. Did we mention that he can warp {{time|Master}} and {{space|Master}}? Manipulate [[LaserGuidedAmnesia mem]][[CharacterRerailment ories]] and [[DreamWeaver dreams]] and more? And he also has a SuperpoweredEvilSide not above trying to kill his own friends [[spoiler: (almost succeeded only a ChekhovsSkill saved them first time, the second he actually killed his best friend (who [[HeroicSacrifice took the shot]] for the {{Love Interest|s}} / MoralityChain), he got better but still)]].
* ''Webcomic/SluggyFreelance'': Torg [[http://www.sluggy.com/comics/archives/daily/090216 is in]][[http://www.sluggy.com/comics/archives/daily/090217 a wacky mood!]]
** The [[http://www.sluggy.com/daily.php?date=090205 beware]] part.
* ''Webcomic/YetAnotherFantasyGamerComic'':
** Lewie the Lich is initially kind of laughable. Then he decides to try playing [[Literature/TheLordOfTheRings Sauron]], and after a couple of misfires (beholders can't wear rings...), he enslaves ''a mountain of monsters''.
** This trope could actually be considered the [[PlanetOfHats hat]] of many of the comic's protagonists, both monstrous and otherwise. [[http://yafgc.net/comic/0574-not-the-blood-of-coritanus/ Just for another example]], underestimating one of the bigger {{Cloudcuckoolander}}s on the mountain, the Chimera, can result in a TotalPartyKill.
** Unless [[http://yafgc.net/comic/0599-the-kings-words/ the Beholder King]] is the biggest {{Cloudcuckoolander}}, in which case it should be noted [[http://yafgc.net/comic/2166-take-it-outside/ he can take on a goddess]].
* Coyote in ''Webcomic/GunnerkriggCourt'' has incredible power at his command. Most of the time, he just uses it to have fun without causing (too much) trouble. On occasion, however, he uses it for ''very'' cruel acts.
* ''Webcomic/CucumberQuest'': YA BOY NOISEMASTER, the second of the Disaster Masters to show up. While smarter than the first he's a colorful hammy DJ who's JiveTurkey demeanor hides a cunning mind. His "hype man" personality is later revealed to be an act used to annoy his boss, and underneath that he resents the Nightmare Knight and tries to defy his role in the story by blowing up an entire city.
* There are a lot of downright clownish characters in ''Webcomic/AwfulHospital''. Almost all of them have it within themselves to bring you to a gruesome end. Given that the titular hospital's located in the Noisy Tenant universe, which you can see in the Web Original folder, it's only natural.
* Sparky from ''Webcomic/TheLastMechanicalMonster''. A ninety-nine year old supervillian who's completely out of touch with modern society after serving a sixty-four year prison sentence. Pretty amusing comedy there, right up until he restores one of his flying, flame throwing robots...
* Tiffany of ''Webcomic/{{Precocious}}'' spends most of her time painting on walls, sleeping in an adorable manner, and digging in her backyard when some random whimsy doesn't strike her. But she also has a non-aggression pact with the local mob.

[[folder:Web Original]]
* At times, Dr. Insano of ''WebVideo/TheSpoonyExperiment'' and ''WebVideo/AtopTheFourthWall'' seems like an IneffectualSympatheticVillain, but there have been times where he's been a somewhat legit menace, such as the times he took control of the giant robot Comicbook/{{Neutro}}, discovered the Anti-Comic Equation (with Warrior #1, a comic so irredeemably awful it distorted the space-time continuum), and hired Squall to assassinate Spoony. Despite all this, Spoony still let him [[GoKartingWithBowser assist him with the review]] of the awful film, ''The Clones Of Bruce Lee''.
** One could argue that wasn't exactly a [[CoolAndUnusualPunishment reward]] for good behavior.
** Also, according to some interpretations of the ContinuitySnarl, that one was a clone.
* The Noisy Tenant series of {{Creepypasta}} is an entire mythology of this. It's an entire building complex of whimsical, decrepit recreations/mockeries of modern places, like Silent Hill designed by the same people who did Pee-Wee's Playhouse. And it's filled with funny and whimsical inhabitants like [[http://scythemantis.deviantart.com/art/The-Hospital-another-horror-story-364122993 Dr.]] [[http://scythemantis.deviantart.com/art/The-Hospital-II-364837295 Phage]], a smiling man-sized bactereophage with a ridiculous bow-tie who performs horrible and unnecessary surgeries on people who end up in his office. Or Harmburger, a tottering anthropomorphic hamburger who [[http://scythemantis.deviantart.com/art/HARMBURGER-A-Horror-Tale-362001994 tries to slaughter people in his freezer of alien meats]] or, with the help of similarly whimsical/horrible cronies resembling an anthropomorphised barbecue grill and meat grinder, [[spoiler: brainwashes all of humanity with his tainted meat, which also infects them with horrible parasitoid brain-flies that are then sold to some other dimension, in the [[http://www.burgrr.com/ burgrr.com]] ARG/creepypasta]].
* The Evil League of Evil in ''WebVideo/DoctorHorriblesSingAlongBlog'' features such silly gimmicks as Dead Bowie and Fake Thomas Jefferson, but they're all unrepentant murderers at the very least.
** It says something that the League's leader is ''a horse'' that seems to be universally recognized as the embodiment of all evil.
* ''WebAnimation/IfTheEmperorHadATextToSpeechDevice'' has a few examples:
** "[[EmbarrassingNickname Little Kitten]]". He's the series' ButtMonkey, constantly insulted by everyone and ComicallyMissingThePoint half of the time. He's also [[spoiler:the Captain-General of the Custodes]] and capable of calling down copious amounts of whoopass.
** The Custodes themselves. As Fyodor finds out the hard way, though their ways might be silly and slightly homoerotic, they're still very much the elite among elites of the Imperium's fighting forces.
** Cegorach. He looks like a deranged clown and speaks in Joker font, but he ''is'' a PhysicalGod and quick to educate the ignorant on Why Not To Annoy Deities 101.
** Magnus. He might spend most of his time used as a punchline for the Emperor... but it's ''the Emperor'' who's taunting the incredibly powerful psyker. [[spoiler:Karamazov and the assembled Inquisition army learn this to their detriment when Magnus nonchalantly sends them into the Warp with little more than a gesture.]]
** Kaldor Draigo joins these ranks as well. Even after having gone friggin' insane due to warp exposure, to the point he's become a sort of power-armored, bearded ScrewySquirrel, he's every bit as [[MarySue Sue-ish]] as he always was and even if you're [[spoiler:a Demon Primarch who just went OneWingedAngel]] he'll take you down before you can ''blink''.
* The Evil Mastermind, an EvilGenius from the ''Roleplay/GlobalGuardiansPBEMUniverse'', is this. He favors grandiose [[ThePlan schemes]] within schemes within schemes within schemes. (Whaddaya want? He's a super-intelligent twelve year old boy.) Most of the heroes consider him a joke. But you know, he did almost poison New York City's whole water supply that one time. And other time he actually had control of the nation's air traffic control systems for nearly half an hour...
* Generator (Jade Sinclair) of the Literature/WhateleyUniverse. She's cute, she's wacky, she invents crazy stuff, she looks like she's only ten... She stopped a supervillain with the powers of the werewolf by ''nailing him to a tree with railroad spikes''. She destroyed a Syndicate hardsite by killing their minions and making it look like she had turned them into zombies. She once broke a close friend out of a magical trap... by firing an anti-tank weapon at it. She's weaponized her hair barrettes, makeup compact, and at least one of her plushy toys. Her shoulder angels nearly caused open warfare across the Whateley Academy campus.
* [[Film/PetesDragon1977 Elliott]] in Website/{{Rplegacy}}'s ''Dark Clouds Gathering'' fantasy crossover [=RPG=] is a good-natured goofball most of the time. God help you [[BerserkButton if you mess with any kids]] when he's around to see you doing it, though.
* Even if he's a complete fool who doesn't know what he's doing, even if he is AffablyEvil, Nappa from ''WebVideo/DragonBallZAbridged'' is still virtually unstoppable to the most powerful human.
* There have been many occasions on ''WebAnimation/DeathBattle'' that deliberately pitted a funny and light-hearted character against a DarkerAndEdgier counterpart, and on [[spoiler:nearly every one of those occasions, the silly character has won]]. The crowner has to be [[spoiler:[[WesternAnimation/MyLittlePonyFriendshipIsMagic Rainbow Dash]] giving a CurbStompBattle to [[Franchise/{{Transformers}} Starscream]]]].
* Imaginee from ''WebAnimation/TheAutisticWorldOfTheAutist''. [[LargeHam Hammy]]? Yes. [[LaughablyEvil Funny]]? Yes. [[NotSoHarmlessVillain Sadistic psychopath]] with a thing for MindRape. [[NightmareFuel HELL YES!]]

[[folder:Western Animation]]
* ''WesternAnimation/DuckTales'':
** Fenton Crackshell is a henpecked MommasBoy who tends to get the worst of it in most of his appearances...until he puts his surprising cleverness, determination, and the Gizmosuit to work, at which point it becomes evident why he gets called an {{expy}} of Robocop.
** Launchpad [=McQuack=] could sometimes be dismissed as a {{Cloudcuckoolander}} and a [[TheDitz ditz]], but under pressure ([[PapaWolf such as when the boys are threatened]]), he reveals himself as more clever than is immediately apparent and capable and courageous enough to be genuinely heroic.
* ''WesternAnimation/KimPossible'':
** HarmlessVillain Drakken and [[TheDragon Dragon]] DarkActionGirl poster girl Shego would arguably be {{Not So Harmless Villain}}s without someone to foil their plans. Once, they attempted to build an army of cute little toy robots.... [[ZergRush 100,000,000 of them]].
** The [[TheMovie first movie]] reveals [[BadFuture what happens]] if the heroes were out of the picture.
** Ron could also fit: when he is temporarily made a villain in one episode, he's unstoppable. Shego (who rightly shows disdain for her boss Drakken's incompetence and demonstrated in the first movie how incredibly dangerous she'd be if she treated villainy as [[PunchClockVillain more than just a job]] and [[BrilliantButLazy applied herself]]) is ''terrified'' of Evil!Ron.
*** When he's back to his normal self, and two villains threaten Kim's life in the finale, man oh man, is he [[BewareTheNiceOnes FURIOUS.]] Needless to say, it doesn't end well for them.
*** In the BadFuture of "A Sitch In Time", he utterly trashes Drakken (who is now super-buff), after Shego reveals that it was she who broke up the Kim/Ron team by getting Ron's mother transferred to Norway.
** Lucre was also a surprisingly effective villain with his lame gimmicks.
** Kim too. Earlier seasons, she was joking around with the villains, but when that didn't work, she resorted to her fists. Oh, and, [[BewareTheNiceOnes push her too far-and it's not pleasant.]]
* Dr. Robotnik as he appeared in ''WesternAnimation/AdventuresOfSonicTheHedgehog'' is regarded as less competent than his deadly serious ''WesternAnimation/SonicSatAM'' counterpart. But he and his robot minions Scratch and Grounder execute any number of formidably dangerous plans to take over Mobius that only fail because of Sonic, and they often succeed at capturing or otherwise incapacitating Sonic. It often happens that Sonic's actions do nothing more than undo the damage that Robotnik had ''already done''.
* The supervillains in ''WesternAnimation/TheVentureBrothers'' are indulged for precisely this reason. In particular, the Monarch seemed content for years to engage in a cat-and-mouse (or "cat-and-also-cat" as he described it) rivalry with Dr. Venture, preferring to live out a hero/villain fantasy with the disinterested scientist than actually kill him when he had the opportunity. The early episodes would even make him seem like a HarmlessVillain if not for his habit of killing his own henchmen. [[spoiler:Then he loses the right to arch Venture, and promptly murders his next five archenemies out of frustration.]]
* Cheryl and Pam of ''WesternAnimation/{{Archer}}'' are for the most part a cheerful head case and a horny, fun-loving {{Gasshole}} respectively, but Cheryl is also a pyromaniac who once threatened to crash a helicopter she was a passenger on just to drag a confession out of her brother, and Pam is a full-blown badass who paid for college by fighting in underground combat leagues-- killing more than a couple of opponents in the process.
* ''Franchise/TeenageMutantNinjaTurtles'': Shredder from ''WesternAnimation/TeenageMutantNinjaTurtles1987''. ''WesternAnimation/TurtlesForever'' explicitly spells out that he and Krang are sitting on technology powerful enough to ''completely take over the multiverse'' if used by someone with brains. Then there's the AllJustADream episode where the Turtles see what would happen if they weren't around-Shredder [[TheBadGuyWins would actually succeed at taking over the world.]]
* Skeletor from Creator/{{Filmation}}'s ''WesternAnimation/HeManAndTheMastersOfTheUniverse1983'' was portrayed in a ridiculous manner at times, but there's no doubt that if He-Man and his allies didn't exist, he would have been able to create much chaos and, possibly, take over Eternia completely.
* Self-proclaimed boy genius Jack Spicer from ''WesternAnimation/XiaolinShowdown'' starts off as the main villain but [[BadassDecay slowly slips into a mockable state]] as more powerful villains show up, even to the point of being a fanboy of the Prince Of Darkness, Chase. By season three, the Xiaolin monks are defeating him for sport, fight scenes with him last on average three minutes, and he only lays claim to one Shen-Gong-Wu, the ridiculous Monkey Staff. Cue the season finale, Time After Time pt. 1, where Omi freezes himself to get to the future, and in his absence, Jack ''takes over the world'', including imprisoning the remaining three Xiaolin warriors and the three main villains of the show.
* In spite of the silliness of the show, the villains from ''WesternAnimation/{{Freakazoid}}'' managed to be more or less serious enough to appear dangerous. But if you look at him from the perspective of the bad guys, Freakazoid himself completely nails this Trope.
* In ''WesternAnimation/TheSecretShow'', a villain simply known as 'The Clown' appears and babbles on about taking over the world, while seeming completely ridiculous. The main characters decide to ignore him in favor of more visible threats, and The Clown, unopposed, takes over the world in short order.
* An episode of ''WesternAnimation/PhineasAndFerb'' had a BadFuture that occurred after [[TheCassandra Candace]] manages to bust her brothers, which also results in Perry being taken out of commission for a few months. Without anyone to oppose him, Dr. Doofenshmirtz manages to TakeOverTheWorld (or at least [[WhereTheHellIsSpringfield the Tri-State Area]], it's not really clear). Admittedly, the actions of MoralGuardians helped him, but not being opposed was still a factor.
* ''WesternAnimation/InvaderZim''
** Most of the time, the title character either falls victim to his own GeniusDitz nature or completely fails to properly use his extremely advanced technology. The few times he's half-way competent however show that he is ''very'' good at causing large scale mayhem and destruction, even if sometimes [[MikeNelsonDestroyerOfWorlds he destroys the wrong thing]].
** In one episode, Zim locks [[RobotBuddy GIR]] into "Duty Mode" (the red-eyed, serious version), and he promptly becomes much more evil and competent than Zim himself, including deciding that Zim is a threat to the mission and needs to be eliminated. Long story short, Zim just barely turns him back to normal in time to prevent a KlingonPromotion.
* ''WesternAnimation/JusticeLeague''
** ''Unlimited'' episode "Flash and Substance" focused on the Flash and his RoguesGallery. Flash's villains might be incredibly silly theme-based, pun-spouting PunchClockVillain holdovers from UsefulNotes/{{the Silver Age|OfComicBooks}}, but when the fighting breaks out they're able to easily take out [[PhysicalGod Orion]] and fight competently against the Goddamn Batman.
** Flash himself is an excellent example. Wise-cracking hero with a friendly and cheerful disposition, constantly flirting and a hopeless romantic... who is also one of the most conscientious of the League in regards to collateral damage, regularly talks villains into giving up, and, if that doesn't work, can single handedly defeat living gods like [[spoiler:Brainiac merged with Luthor]].
* ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy''
** [[TheMovie "Billy & Mandy's Big Boogey Adventure"]], [[spoiler:the dark overlord in the BadFuture turns out to be [[TheDitz Fred Fredburger]]]].
** Billy himself maybe a [[KindheartedSimpleton cheerful]] [[TheDitz moron]], but can even terrify ''Mandy'' whenever he gets mad.
* ''WesternAnimation/TeenTitans'':
** Beast Boy. He's a KidAppealCharacter and the resident PluckyComicRelief and ButtMonkey, but [[SuperpoweredEvilSide don't make]] [[BerserkButton him]] [[LetsGetDangerous angry]].
** Control Freak is always played for comic relief, but he's also essentially a RealityWarper with his special remote control.
** The Amazing Mumbo may seem ridiculous and corny with his silly stage-magician gimmick, but [[DomainHolder he's got a world inside his hat where he's in complete control and he's all too happy to suck you in and make you part of the show.]] And even outside this little world of his, he's surprisingly agile, and his tricks pack a nasty punch.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** Discord is a [[FauxAffablyEvil cheerful]], fun-loving, [[RealityWarper reality warping]] [[TheTrickster trickster]] who enjoys chocolate rain, cotton candy clouds, [[BreadEggsMilkSquick and]] [[CorruptTheCutie corrupting]] and [[BreakTheCutie breaking]] ponies and laughing at their misery as their entire world crumbles around them, literally and metaphorically. But underneath it all, the other ponies (especially Fluttershy) learn that [[JerkWithAHeartOfGold he's not all bad]].
** Also, don't ever [[BerserkButton break a Pinkie Promise...]]
** On that note, don't mess with the Cutie Mark Crusaders. After Babs Seed pushed them hard enough, they rigged a trap in a parade float that would make TheATeam blush ([[ShoutOut To music that sounded suspiciously like the A-Team's theme, no less]]) and lured Babs into stealing it with a BatmanGambit. The only reason it failed is because the CMC had a change of heart and saved Babs from it.
** The [[SmallNameBigEgo "World Famous"]] Flim Flam brothers are a pair of con men who keep their sights set relatively low, aiming to scam small groups of ponies out of money or farm land. Then the FridgeBrilliance kicks in when you think about their Super Speedy Cider Squeezy 6000 and realize they're a pair of [[GadgeteerGenius Gadgeteer Geniuses]] who can create a vehicle that is years ahead of any other technology in the world. ''[[FromBadToWorse Then]]'' the Season 5 Finale comes around and shows that, if nobody holds them back and they ever decide to set their sights a bit higher, they could and would reduce everything in sight to a pollution-choked wasteland dotted with smoke-belching factories, causing a BadFuture equatable to if Sombra or Chrysalis succeeded.
* Cobra Commander from ''WesternAnimation/GIJoeARealAmericanHero''. One of his plots involved [[DefaceOfTheMoon carving the image of his face into the moon]]. On the other hand, he has a knack for coming up with a lot of crazy plans, and some were CrazyEnoughToWork if it wasn't for G.I. Joe and betrayal by his minions.
* ''WesternAnimation/TransformersAnimated'': Prometheus Black[=/=]Meltdown, despite his DiscoDan style outfits and cartoony MadScientist nature is, ''by far,'' the most dangerous human villain on the show. That may not seem like much, considering [[HarmlessVillain the other villains]], but he's almost on the same level of evil as the Decepticons. While other human villains at most got a single episode of being at all dangerous, Meltdown was ''consistently'' portrayed as a genuine threat nearing if not equaling the Decepticons -- who in this continuity, are incredibly dangerous threats that are more than a match for the team on an equal playing field.
** Among the Decepticons themselves, there's several cases of this.
*** Blitzwing, with his SplitPersonality and his wacky [[CloudCuckoolander Random face]] is such a riot that sometimes you forget he's a merciless giant war machine who's armed to the teeth and capable of hunting you down by land or by air.
*** Swindle is an ArmsDealer with mannerisms based on ''Ron Popeil''.
*** Despite his overinflated ego and propensity for running his mouth, Starscream can be surprisingly cunning and dangerous.
* In ''WesternAnimation/SpongeBobSquarePants'', Plankton is, at his best, a LaughablyEvil villain, and at his worst, a [[IneffectualSympatheticVillain pitiable]] DesignatedVillain whose only crime is that he's TheRival to [[TookALevelInJerkass Mr. Krabbs]]. However, in TheMovie, he frames Mr. Krabs for the theft of [[JerkassGods Neptune]]'s crown and gets him frozen in ice, and takes over Bikini Bottom and [[MoralEventHorizon makes everyone his slave]].
* ''WesternAnimation/LooneyTunes'':
** WesternAnimation/DaffyDuck and WesternAnimation/PorkyPig could be ''very'' silly...when they weren't, y'know, [[AxCrazy running around with axes]]. UpToEleven in ''WesternAnimation/DuckDodgers'' where Daffy is captain of a military starship.
** Siegfried's VillainousBreakdown in ''WesternAnimation/WhatsOperaDoc''. Bet you didn't think WesternAnimation/ElmerFudd could be terrifying.
* WesternAnimation/{{Goofy}}, when he gets DrunkWithPower and put in charge in "[[WesternAnimation/HouseOfMouse Sandwich Makers]]".
* ''WesternAnimation/AladdinTheSeries''
** One episode had the recurring villain, Mirage, convince Chaos, who was visiting, to make a little, well, chaos, in the palace of Agrabah where Aladdin and Jasmine are holding a dinner for some nobles. Chaos is a silly blue cat with wings. He also has more power in his whisker than a palace full of genies, can grant his own wishes, shrunk Jasmine to the size of an insect and nearly got her stepped on by her own husband when she ordered him to stop his mischief, and was able to poof up an EvilTwin that Aladdin was forced to fight to a near standstill after [[IdiotBall Genie]] mentioned the only predictable part of Aladdin's adventures was he always won. Chaos ''terrifies'' Mirage, who is the current personification of evil, and who has proven quite capable of offing the heroes and wiping Agrabah off the map. And after the series, Chaos appeared one last time in a short Aladdin comic in ''Magazine/DisneyAdventures'' in a DeusExMachina type ending by stripping the powers of a devilish entity known simply as "Evil", who was near to defeating Aladdin, when he felt things were getting too predictable.
** The Genie himself gets a couple of surprisingly scary moments, despite normally being a lovably goofy lug. Especially when one takes into account that, since he's no longer bound by the rules of the Genies by virtue of being freed of his lamp, he's now capable of ''killing people if he wants''.
* [[LargeHam The Duke of Detroit]] from ''WesternAnimation/{{Motorcity}}''. Dresses like a really rich guy out jogging, is LargeHam personified, and loves to break out into random karaoke. He's also one of the most influential people in Motorcity, with enough wealth and artillery at his disposal to make your life a living hell, anytime he sees fit.
* Otto, from ''WesternAnimation/SuperRobotMonkeyTeamHyperforceGo'', may [[GeniusDitz come across as a clown]], but some clowns are [[ChainsawGood quite handy with chainsaws]].
* The Vreedle Brothers introduced in the ''WesternAnimation/Ben10AlienForce'' part of the franchise are idiots. Idiots with a ''tremendous'' overabundance of firepower and love of using it.
* ''WesternAnimation/GravityFalls'':
** Old Man Mcgucket, the local kook, has proven himself perfectly capable of mass destruction. In "Legend of the Gobblewonker" we learn he builds highly-destructive HumongousMecha as a coping mechanism for rejection and loneliness, and in "Land Before Swine" it's implied [[spoiler: he ''ate'' his way out of the belly of a pterodactyl]]. Justified in "Society of the Blind Eye", when he [[spoiler: revealed to be a former genius scientist, who vent insane after using his mind-erasing gun on himself too many times. In the same episode he defeats the leader of the Blind Eye society by walking towards him, ignoring all shots from his memory-erasing gun, which doesn't on him due to his insanity, knocking said gun out of his hands and headbutting him into unconsciousness]].
--->'''Mcgucket:''' [[spoiler:[[InsanityImmunity You can't break what's already broken!]] ]]
** And then there's Bill Cipher from "Dreamscaperers", an EldritchAbomination whose goofy appearance and laid-back personality hides massive amounts of power and a twisted sense of humor. When he graduates to full BigBad in Season 2, he becomes more vicious and manipulative, but never loses his "silly" personality.
** And that's completely ignoring Stan Pines, who goes through great lengths to make as much money from each and every situation he finds himself in. Stuff his great nephew in a wolf-boy costume and make him dance for money? Get into a wheel-of-fortune-esque television show through pure greed and selfishness, only to tragically lose because he literally didn't know what the word "please" was? Par for the course. But if you threaten Dipper's or Mable's lives, he's quick to beat the shit out of you and anyone you may have helping you. As a horde of bloodthirsty zombies could attest, if they weren't currently dead. Again.
** Subverted with [[PoliceAreUseless Sheriff Blubs]] and [[CluelessDeputy Deputy Durland]] in "Irrational Treasure". You'd think they'd start acting competent after getting order concerning an AncientConspiracy, but they're still as [[MinionWithAnFInEvil idiotic and useless as before.]]
* Varrick from ''WesternAnimation/TheLegendOfKorra'' may act flighty and absentminded, but he hides behind that ditzy exterior [[spoiler:a ruthless CorruptCorporateExecutive who is willing to start a civil war between the Southern and Northern Water Tribes just to grab a few bucks from the conflict]].
** Bolin was never exactly a slouch in a fight, but his rather simple pro-bending style, coupled with his [[TheDitz personality]], led to him being more of a backup comic relief for the first two books. Once he [[spoiler:learns how to lavabend]], however, he becomes a force to be reckoned with, shows of his raw power stopping fights before they even start.
* Aku from ''WesternAnimation/SamuraiJack'' is so [[LaughablyEvil downright silly and hilarious]] at times that new viewers can be forgiven for seeing him as a HarmlessVillain if their first episode is something like ''Aku's Fairy Tales'' or ''Jack Vs. Aku''. In episodes like ''Jack Under The Sea'' or ''Jack And The Zombies'', he reminds you just how terrifying the [[VoluntaryShapeshifting shape-shifting]] [[NighInvulnerability practically invincible]] [[MadeOfEvil embodiment of evil]] can really be.
** For a non-villainous example, there's that [[Anime/MyNeighborTotoro Totoro]]-like GentleGiant that follows Jack around in ''Jack and the Creature''. It's big, goofy-looking and incredibly dimwitted, but when it sees Jack being overpowered and viciously beaten by a gang of robot bounty hunters, the Creature transforms into a gargantuan murder-machine with MoreTeethThanTheOsmondFamily and [[CurbStompBattle absolutely trashes all the robots with no trouble at all]].
* Ty Lee from ''WesternAnimation/AvatarTheLastAirbender'' is a bubbly, cheerful acrobat who babbles about reading people's auras and does things like walking on her hands for no particular reason, but when she actually fights, she is more terrifying than an army of Firebenders.
** Also Avatar Aang, the only person scarier than Ty Lee. He is generally a bit "air-headed", enjoying penguin rides, fruit pies, and bad jokes, not to mention that he is a TechnicalPacifist. But there's a reason it's TechnicalPacifist: provoke him, and he can and will MindRape you and ''rip out your soul''.
** King Bumi appears to be a crazy old man who loves candy, bad jokes and ridiculous outfits. However, he's also one of the strongest Earthbenders in the world, and took back an entire city from the Fire Nation in under eight minutes (Granted, the Fire Nation soldiers were depowered due to an eclipse, but that doesn't stop Bumi from crushing tanks like beer cans and throwing buildings across canyons). Oh, and since he had been restrained at the time, he did all that by earth bending ''with his face.''
* This happens a ''lot'' in ''WesternAnimation/AdventureTime'', since the world the show takes place in is both a CloudcuckooLand and a WorldOfBadass. Some of the most notable examples are Finn, a goofy IdiotHero teenager who has nonetheless been taking down omnicidal {{Eldritch Abomination}}s since childhood; Jake, a lazy TalkingAnimal who has been shown going full-on PapaWolf in protection of his [[BigBrotherInstinct brother]] or children; and Ice King, a [[LaughablyEvil comedic]] IneffectualSympatheticVillain whose [[AnIcePerson powers]] are in fact near PhysicalGod levels and who can be fairly [[PsychopathicManchild disturbing]] and [[LackOfEmpathy sociopathic]] sometimes.
* [[TheDragon Jose]] from ''WesternAnimation/CyberSix'' is a pint-sized little kid who throws tantrums, has a beyond ridiculous LeitMotif, and [[GettingCrapPastTheRadar goose-steps]] from place to place. It's enough to make you forget he's a MadScientist with a [[EvilGenius genius-level IQ]] who has failed to kill Cyber Six thanks to dumb luck ''alone'' on more than a few occasions.
* In ''WesternAnimation/TaleSpin'' an antagonist's threat level is directly proportional to their zaniness. For example, Don Karnage is a complete goofball and very serious threat, whereas Shere Khan is a straight-laced CorruptCorporateExecutive and helps the heroes as often as he antagonises them.
* The Urpneys of ''WesternAnimation/TheDreamstone'' were usually incompetent and meek even by HarmlessVillain standards. However several episodes imply that were it not for them being the Sleeping World's {{Cosmic Plaything}}s and the heroes being BornLucky, they could likely pull a lot of schemes off. Both "Albert's Ailment" and "The Spidermobile" have them in full control for almost the entire episode, only losing due to a last second fluke allowing the heroes to get the stone back.
* Ed, the biggest of the three titular characters in ''WesterAnimation/EdEddNEddy'', is the walking personification of loveable goof. Dumber than a box of rocks (except for comics and horror/sci-fi movies) the only times he doesn't have a big dopey smile on his face is when he's too confused, or running away from someone. He has occasionally shown himself to have an astonishing amount of strength, but usually only as [[RuleOfFunny part of a gag]]. THEN came the episode where he was furious the entire time [[spoiler:because he had a rock in his shoe]], and ''laid waste'' to all in his path. Including ripping an entire tree-trunk from the ground. Even Sarah, Ed's [[PintSizedPowerhouse nearly-as-strong]] and [[SpoiledBrat eternally tormenting little sister]] that rules over him (and Jimmy) with an iron fist, was terrified of what Ed was doing.
* ''WesternAnimation/StarVsTheForcesOfEvil'': The title character, Star Butterfly, is a flighty, impulsive teenage girl... who, with or without her magic wand, can kick serious butt when she or her loved ones are threatened. This is most vividly demonstrated in the season one finale "Storm the Castle".
* Cartoon characters in general. People rarely think about it cause it's always PlayedForLaughs, but cartoon characters are repeatedly shown to be capable of numerous feats of strength, speed and durability far beyond any natural living creature. Which means that if they were to manifest in our world (Or crossover with a more realistic setting) picking a fight with them would be a VERY bad idea. This is actually examined in ''Film/WhoFramedRogerRabbit'' where Toons are real, their ''only'' weakness is The Dip, and apparently the only reason they're not a serious threat is because they ([[BigBad save for one]]) would rather be funny than hurt people.
* ''WesternAnimation/StevenUniverse''
** [[spoiler:Smoky Quartz]] definitely qualifies. Being a fusion between [[spoiler:Steven and Amethyst]], she was created out of their collective insecurities, which makes her look... unconventional. [[spoiler:She is rather chubby, has a third arm growing out of her elbow, [[ImprobableWeaponUser uses a yo-yo as a weapon]] and constantly makes jokes and puns. However, when it comes to battle, [[CurbStompBattle she easily owerpowers]] [[TheAce Jasper]], while proving, that her yo-yo attacks is both [[KillerYoYo dangerous]] and [[ConfusionFu unpredictable]].]]
** Hell, Amethyst herself. She's always fooling around and seems upbeat and carefree, and though she's not the most competent member of the team, she's perfectly capable of holding her own in combat. [[spoiler: Notably against Pearl.]]
* ''WesternAnimation/ThePowerpuffGirls'': Bubbles. She may act goofy and ditzy most of the time, but she's just as good as her sisters when it comes to kicking villains' asses.
* Stumpy from ''WesternAnimation/{{Kaeloo}}'' can actually be quite dangerous. The most notable example is Episode 105, where he manages to [[spoiler: ''very nearly'' erase the rest of the main four from existence, and then takes over the animation studio]].

* The teddy-bear cholla, a cactus native to the deserts of the American southwest, from a distance looks as cute and fuzzy as the name implies. Those fuzzy-looking spines, however, frickin' mean business! Entire segments of the plant will break away and cling to their victim like a gigantic, vampiric cockleburr. This is also simultaneously the teddy-bear cholla's main defense against herbivores and their primary form of reproduction (in that the segments sprout as soon as they're removed from their victim). They tend to grow in patches, making large swaths of the Sonoran Desert impassable. The cactus is so devious that locals like to repeat an old wives' tale that claims plants are able to reach out and stick passers-by, which, by the way, inspires its other common name of "jumping cholla."
* [[EverythingsBetterWithPlatypi The platypus]] is an odd animal, even among the grab-bag of evolutionary oddities that make up the ecology of Australia. Possessing a duck's bill, a beaver tail, and otter-like feet, it further distinguishes itself by being one of only five species of mammals to lay eggs. Beware the male ones, though, as they produce a venom that causes excruciating, intractable pain in humans, lasts for weeks and is noted for not responding to analgesics like morphine. This venom is not actually fatal - but a dose of morphine that ''is'' will not make a dent in it. Physically severing the nerve transmitting the pain signal is actually considered valid medical treatment to platypus venom. From ''Website/{{Cracked}}'':
-->[[http://www.cracked.com/article_15853_the-6-cutest-animals-that-can-still-destroy-you.html The platypus is Mother Nature's way of saying, "I made this thing out of spare parts I found on the workshop floor, and it can still fucking cripple you."]]
* Guess which animal in Africa has killed the most people? Black mamba? Lion? Cheetah? Hyena? Human-baby-eating-monkeys? No, my friend. It is the ''hippo''. Yep. The big fatty with cute little ears. Word of advice: When in Africa, don't ever go near where a hippo lives, because they ''are'' territorial and if they see you, they ''will'' chase you and you better have a runaway truck nearby, because they ''are'' faster than they look. Why should you be so worried about escaping an angry hippo? Why is the death rate so high? [[http://images.travelpod.com/users/shieldsontour/world_tour_2008.1215108420.angry-hippo.jpg Hippos aren't afraid to bite.]] And the lesson is? Don't antagonize an animal that's eager to bite you with teeth as big as bowling pins! There's a reason why Steve Irwin was afraid of them.
** Sometimes hippos don't bite. They simply want to go back into the water, and don't give two fucks about what or who is on the way. Getting hit by one is just like getting hit by a truck.
* Caterpillars are a perennial source of visual amusement for humans. After all, the typical caterpillar is soft, fuzzy and too interested in eating to notice the big humans poking and gawking at it. However, there are some caterpillars that, despite looking rather peculiar or ridiculous, are actually dangerous. One offender is the caterpillar of the puss moth, which is a big, fat, green caterpillar. If threatened, it rears up to show off its big, pink head, which it sinks into its neck, so that one sees a face with what appears to be a pair of lips underneath its mouth. Any predator (animal or human) that does not get the hint to leave it alone from this threat display will then find out that the "lips" serve as the opening to a gland that squirts out a jet of caustic formic acid. The caterpillar of the flannel moth is far worse, appearing as a disheveled and strangely adorable ball of fluff. [[NamesToRunAwayFromReallyFast Do not touch any caterpillar with the nickname "asp!"]] The fluff hides numerous venomous spines that cause excruciating pain, comparable in agony to snakebite, and, with the added bonus of causing bleeding, blistering rash at the site of contact.
* Rhubarb looks a lot like celery with a red or pink stalk (it can have a green stalk too, so beware). The leafstalks of both plants are edible, as are Celery leaves. Rhubarb leaves, however, have so much oxalic acid concentrated into the tissue so as to be deadly. While oxalic acid is what gives rhubarb its deliciously tart flavor, in large quantities, it can cause immense harm, in that, at toxic doses, crystals of oxalic acid will form in the blood, and when the blood is filtered through the glomeri of the kidneys, these crystals will lacerate the tissues of the kidney, so that the poisoned person will bleed to death by urinating blood.
* The Cape Buffalo: It looks kinda like a big dumb cow, but beware, this massive bovine is considered one of the Big Five of African big game (Said list contains lions, leopards, rhinos, and elephants. That's right, this (allegedly!) big dumb cow is considered to be on the same difficulty level as lions and elephants), and is known as the Black Death to professional game hunters, due to how hard they are to kill, and their tendency to hunt their hunters back if they've been wounded. They are known to ambush game hunters (and lion cubs) and kill them horribly by goring and trampling them to death. They're herbivores, but kill more humans, per year, than lions do.
* Mosquitos. They're annoying little pests with big doofy eyes and who buzz around dopily, with hobbies that include leaving behind an itchy bite, buzzing in your ear, and ruining outdoor events, and they go out in one swat. Wouldn't it be scary if they were responsible for more human deaths per year, or total across history, than ''any other organism on the planet'' and our only means of warding them off is avoiding them or hiding from them with repellent and hoping they don't happen to bump into us? Yeah, that's [[NightmareFuel actually the case.]]
* Domesticated pigs. Fat, often pink creatures with curly tails that look too tubby for their little legs, stuff themselves on near everything and look ridiculous when they're running around. As any farmer will tell you, though, pigs are incredibly dangerous when riled, and have been known to kill and eat their caretakers if they're provoked into it (or [[FedToPigs if the caretaker is just knocked unconscious into their pen]]).
* [[EverythingsBetterWithMonkeys Chimpanzees]] are known for being human-like, to the point where they are dressed in human outfits. Also, they can make a funny, huge, toothy grin they flash for the cameras, it makes them look devilish. The bad thing is, it's not a grin, but a mouthful of very large teeth being bared. One chimp even attacked his caretaker once. And don't get us started on National Geographic's Frodo...
