History BewareTheSillyOnes / FanWorks

* ''[[Fanfic/WhiteSheepRWBY White Sheep]]'':
** Salem is a DotingParent who spends most of her time [[TooMuchInformation talking about her sex life]] and [[IWantGrandkids trying to get her children to produce grandchildren]]. However, she is still the all-powerful Queen of the Grimm; early on, Salem wants to destroy Vale to get Jaune back, and Cinder barely manages to convince her it's a bad idea. She could and ''would'' do it--the problem is that Jaune would resent her for it.
** Related, part of the reason Cinder talked Salem down was because it would threaten the existing plan, where Cinder gets the rest of the Fall Maiden's power. Cinder thinks she's tricked Salem, but Salem is well aware of her ambitions. She doesn't particularly care, but she still considers murdering Cinder for even trying to trick her.
** Early on, it seems like Salem's plot to set Cinder up with Jaune by having her be his babysitter was just a silly plan caused by not understanding humans (children who grow up together usually end up LikeBrotherAndSister, not in a ChildhoodFriendRomance). However, that was merely the best possible outcome, in Salem's mind. Lavender mentions that the ''actual'' plan, to imprint Jaune on Cinder so that Cinder would care for him and be tied more closely to the family, worked perfectly--[[{{Tsundere}} despite Cinder's protests to the contrary]].

* ''Fanfic/TheBoysRealJustice''
** The [=DC=] villains are seen by the Boys as fruitcakes in silly costumes but are still dangerous villains who shouldn't be underestimated.
** Homelander sees the Joker as a powerless clown with silly makeup. Still, he succeeds in killing dozens of people and savagely humiliating Homelander, severely damaging his reputation as a crime fighter.

* ''Webcomic/HetaliaAxisPowers'' fanfic ''[[https://www.fanfiction.net/s/11886910/1/Gankona-Unnachgiebig-Unità Gankona, Unnachgiebig, Unità]]'': Enduring a day of tension between [[CrazyJealousGuy Germany and Japan]], [[{{Keet}} Italy]] reached his RageBreakingPoint after [[spoiler:Germany pulled a Browning Hi Power on Japan while Japan pulled out his katana on Germany.]]
* [[PrivilegedRival Obsidian]] from ''Literature/TheHungerGames'' 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, 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 [[PsychicTeleportation 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, [[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 [[VideoGame/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.

* Princess Cadence in ''Fanfic/TheGodSquad''. Silly, goofy, constantly talks about sex... but threaten Shining Armor and she won't kill you. That is too quick. She'll just sterilize your entire race so you can watch your entire culture slowly die.
* Luna Lovegood in ''Harry Potter and the Lord of Sevii''. When she learns Neville was killed she unleashes a pulse of Veela magic that nearly kills the heroes and villains alike.
* Clopin, Kaylie's Touceet, in ''Fanfic/PokemonOpalAndGarnet'' is just like [[WesternAnimation/TheHunchbackOfNotreDameDisney his namesake]]: he is hilarious, fun-loving, and silly most of the time, but if you ever think about hurting his friends... WELCOME TO THE COURT OF MIRACLES! (In other words, he will annihilate you with Guillotine. So watch out.)
* ''FanFic/ThePiecesLieWhereTheyFell'': Sweet Surprise, the Full Moon of the Luna Guard, may seem like a ditz, but she holds her rank for a reason.
* ''FanFic/ChildOfTheStorm:'' Albus Dumbledore, BunnyEarsLawyer and CoolOldGuy, is also a very knowledgeable and dangerous wizard, even more so than his canon counterpart. When attacked by four wizards, trained by HYDRA specifically to take him down, he casually defeats them with two absent-minded spells, and later goes up against god-eating RealityWarper that's also possessing an Omega Class RealityWarper. He doesn't just beat it - he ''mops the floor with it''. All in all, there is a ''reason'' why he is RespectedByTheRespected.
** Tony Stark, meanwhile, is so eccentric that his antics are a RunningGag in and out of universe, and is incredibly scatterbrained, especially when he's focused on a project. But he's also ''the'' Iron Man, once built a suit that - even incomplete - was described by a flabbergasted Director Wisdom as "a planetary scale emergency all by itself", and repeatedly flies rings around people in replicas of his armour with nonchalant ease. Accordingly, everyone, friend or foe, treats him with at least grudging respect.
** Doctor Strange, however, arguably takes the cake. He [[BunnyEarsLawyer rarely seems to take anything seriously]], [[PopCulturedBadass often making pop-culture references at the most inappropriate moments]], dresses in strange and colourful clothes, and has a thoroughly [[{{Troll}} mischievous sense of humour]], which often involves stealing small (and not so small) objects that are supposedly under the very highest security, mostly for the hell of it (examples so far include Mad-Eye Moody's wooden leg from its owner, a phoenix feather [[spoiler: containing Harry's mind]] from [[spoiler: Maddie Grey's]] back pocket, and [[ItMakesSenseInContext Loki's detached head]] from the most secure part of Asgard's palace). All of which [[SadClown serves to cover for an epic amount of personal tragedy.]] However, he's also the most dangerous mortal mage alive and one of the most powerful, has centuries [[spoiler: actually, 500 ''millennia'']] of experience fighting {{Eldritch Abomination}}s, and makes a policy of knowing (almost) everything. He has an exceptionally well-earned reputation as TheDreaded, and [[LetsGetDangerous if the jokes have stopped, he's about to show why.]] Even Skyfathers are unwilling to cross him, and for good reason - if nothing else, the crazy bastard is more than happy to [[spoiler: swipe the Tesseract]] and threaten them with it. He's best known, however, for being a MagnificentBastard whose mastery of the XanatosGambit means that ultimately people (by which we mean everyone from {{Badass Normal}}s to the freakin' ''Endless'') do what he wants them to, even when they ''know'' he's manipulating them.
* Pinkie Pie in ''[[https://www.fimfiction.net/story/186145/1/just-another-day-in-ponyville/just-another-day Just Another Day]]'' used to be the most dangerous assassin in Equestria who'd use her [[FourthWallObserver unique]] [[OffscreenTeleportation abil]][[HammerSpace ities]] to kill people. When someone threatens to expose her past to her friends, he's found drowned in the middle of the lake the next day.
* In the ''Series/PowerRangersInSpace''/''WesternAnimation/MightyDucksTheAnimatedSeries'' crossover "[[http://www.paladar.com/fanware/room13/brand70.htm Lost and Found]]", when Cassie Chan finds herself facing Chameleon in battle, his constant shapeshifting leaves her so frustrated that she finally decides to ignore the Rangers' rule against escalating a battle and starts shooting at Chameleon rather than trying to fight him hand-to-hand.
* Pinkie Pie again in ''[[https://www.fimfiction.net/story/418498/good-trooper-gilda Good Trooper Gilda]]''. Acts pretty much like her canon counterpart, barely graduated at the military academy, she's an intelligence officer trying to end the rebellion in the Griff Isles, and Gilda refers to her as "the scary pink mare who likes to talk about mass murder and partying with survivors" because she has seen her doing just that right after finding out enough information to realize she had ''planned the mass murder''.

* Ash's Duskull (Spectre) in ''[[https://www.fanfiction.net/s/11803928/25/Challenger Challenger]]'' is a mischievous spirit who likes to hide in shadows to spook people and wear Ash's hat. According to Agatha, he's also been around since she was a child and the only reason he's not a match for her entire team is because he hadn't found a trainer to bond with yet. When one of Agatha's Gengar provokes him by trying to bond with Ash, Spectre tackles it into the Distortion World and utterly kicks its ass.
* Pierre [=LaPorte=] from ''Fanfic/MaimDeMaim'' as we find out. He's weird and borders on {{Cloudcuckoolander}} but we find out that, under his weirdness, he's [[spoiler:a pedophile and its implied that he's probably committed some crimes against children before finding his way to Japan]].
* Misty's Psyduck in ''Fanfic/PokemonResetBloodlines'' is an even bigger example than in the anime, since he's portrayed as being a bit of a CowardlyLion and BrilliantButLazy. Case in point, he'll intentionally trip over to hit his head so as to trigger his psychic attacks if needed, and if his trainer is in danger, he'll do anything it takes to protect her.
* Episode 7 of ''[[https://my.w.tt/cx9Db5b4YX Final Stand of Death]]'', ''WesternAnimation/CelebrityDeathmatch'' Fic, three of the henchmen of Music/MarilynManson finally gives to see Fusion Gundam up close. They assume they weren’t as much as a threat as they thought. However, back in Episode 2, Spur, ALL BY HERSELF, almost killed members of Music/Blink182 after Mark makes the sounds of a chainsaw, which ended her former life as [[spoiler:Emma "Baby" Bunton. Same with the other Music/SpiceGirls]].
* ''Fanfic/WhiteSheepRWBY'':

* Nejire Hado in ''Fanfic/WhatsInAHoard'' is a bubbly woman who's shorter than most of class of 1A and prone to skipping. When she fights 1A, she beats all of them in under thirty seconds and most of that time is spent fighting Izuku and Bakugo.
* ''FanFic/TheOuroboros'': Mikey [[StepfordSmiler presents himself]] as FunPersonified, always ready to [[SadClown joke around]] even in the worst situations. However, when he learns that their [[FutureMeScaresMe alternate selves]] lied to them in order to steal their identities back on Earth, he flashes back to popping the heads off of bug-like aliens, and idly wonders if they'll have to do the same to their alternates in order to reclaim their lives.
-->'''Mikey:''' ''[to Leo]'' "How similar d'you think carapace is to exoskeleton? Asking for a friend."
* Luna Lovegood in ''[[https://www.fanfiction.net/s/13034223/19/A-Discordant-Note A Discordant Note]]'' is extremely friendly and nurturing as well as prone to odd actions like swimming in a fountain and asking Harry to make sure her new body lactates chocolate milk. But from time to time, she casually reminds the rest of Westeros that she's a six century old Sorcerer-Queen and if she decides to do something, such as replacing the stained glass window behind the Iron Throne with one affiliated with the Old Gods, there's literally nothing anyone (besides her husband Harry) can do besides politely ask her not to.
* ''Fanfic/TheMLPLoops'':
** [[Characters/MyLittlePonyFriendshipIsMagic Pinkie Pie]] is... well, she's Pinkie Pie. However, she's more Pinkie Pie than she's ever been in baseline, has a ''pink [[ComicBook/GreenLantern lantern ring]]'', has replaced [[TabletopGame/Warhammer40000 Slaanesh]] and given Ciaphas Cain a trauma worse than Slaanesh ever could, and is quite happy to extract the punishment for breaking a Pinkie Promise no matter how many loops it takes. '''Beware.'''
** Pinkie specifically warns Berry and Sweetie, fellow Element of Laughter bearers, that theirs is actually the most dangerous Element. Pinkie's Laughter manifests as parties; she could have a knife party or worse. Berry's Laughter manifests as mixing drinks, and she spends a lot of time mixing drinks for immortals; mixing more dangerous variants would be easy. Sweetie's Laughter manifests as music; she once helped sing a world into existence, she could easily sing a song of destruction instead.
** Most of the time, we only see people's reactions to Pinkie's really high-level craziness. In the Sombra War BadFuture variant, we finally see it first-hand. After Pinkie gets permission from Twilight, she goes ''full'' Chaos Goddess of Parties, bringing a galaxy-level party straight on Sombra's head.
--->Normally, Pinkie's smiles were filled with cheer and endless joy. But just this once... just this once, she allowed herself a grin as grim and dark as the world she was in.\\
"iiiiiiiiiiiiiiiiiiiiIIIIIIIIII'''IIIIIIIIIIIIIIIIIIT'S''' '''''PARTY TIIIIIIIIIIME!'''''"\\
The creature that exploded out of the barracks was nephrotic, glimmering, cackling, and dusky dusky pink.\\
Across the battlefield it charged and danced, smacking soldiers away from each other, long curling arms taking darkened helms and throwing them into the massive maw. Mad laughter spun about, the confused armies finding themselves wearing colorful conical hats that oh so incidentally kept them shielded from any assault. Even Celestia paused as the monstrosity whisked past her, blinking in shock when five eyes seemed to wink eagerly.\\
Sombra quickly rose up on his crystal, but it was no use. The thing crawled up and curled around it like a tower, sharp teeth exposed. "OH HO HO HO! SOMBRA, DEAR KING SOMBRA. Are you afraid?" Its voice suddenly dropped to velvet. "You're the guest of honor here, Sombra. You shouldn't be afraid... no, I have something special planned for you. You... should be... '''''COMPLETELY TERRIFIED!'''''"

* Mineta in ''Fanfic/TheSaintAndTheSinner'' is pretty goofy and hard to take seriously due to his small stature and comical nature, but he's also highly intelligent and has proven his cunning in multiple situations, not to mention he can be genuinely intimidating when the situation calls for it. When Mina called Todoroki Mineta's minion, he gave her a DeathGlare and calmly told her to leave, even frightening her with how serious he was.
* ''Fanfic/EquestriaGirlsFriendshipSouls'':
** Pinkie Pie is the same bubbly self that she is in canon... With power that manifest as a semi-separate being made out of her suppressed negative thoughts with ability to infinitely create jaws filled with razor-sharp teeth [[BodyHorror on every part of her body]]. And that's just the beginning of myriad of [[RealityWarper freaky powers.]]
** Bount Trixie is just as silly and hammy as her pony counterpart, but she can back up her ego with her power being just below Captain-level and is able to fight Princess Twilight, Rainbow Dash, and Flash Sentry to a near standstill.
** Cheese Sandwich is a powerful, competent, and intelligent Soul Reaper captain. ...Who acts exactly like his pony self. (that is to say, a male Pinkie Pie)
** Medley of the Zero Division is rather quirky, but she's still a member of, again, the Zero Division, and is thus insanely strong, with a Zanpakuto that can obscure and confuse the senses, but she makes it clear that the Humane Seven will die if they challenge the Soul Palace.
* Izuku in ''FanFic/IzukuMidoriyaTheRabbit'' may be a rather naïve rabbit who frequently suffers from AttentionDeficitOohShiny and ComicallyMissingThePoint, but don't think that makes him harmless. He's a 75 pound KillerRabbit with SuperStrength, SuperSpeed, and a willingness to rip out the throat of anyone he believes is an enemy, as Aizawa almost found out.

* ''Fanfic/LoveAtFirstSightOnceUponATime'': Emma is kind and quirky, constantly making dorky jokes and dancing everywhere she goes. She even takes to wearing a clown nose later in the story. However, she is also a former assassin and able to take multiple groups sent to kill her without breaking a sweat. She also kills her clients who hire to kill people. She even reveals that part of the reason that she retired was as much her boredom as it was her being tired of killing innocent people.
* ''Fanfic/CListers'' focuses on Batman's lesser rogues in various comedic slice of life shenanigans, portraying them as a group of lovable, goofy TrueCompanions. Every so often, however, you're reminded that they're hardened criminals who are extremely ruthless, and all of them have countless murders under their belt. Even the seemingly harmless Killer Moth and Polka-Dot Man won't even blink when circumstances require them to kill someone.

* ''Fanfic/ItsAlwaysTheQuietOnes'': Luna the lovable CloudCuckoolander turns out to be capable of summoning mind-destroying, human-eating alien jellyfish.

* ''Fanfic/OldManHenderson'' is one of the better known examples, and quite intentionally so by part of his player; he intended to make him as ridiculous as possible to both minimize the amount of questioning of how and why he's doing things (coupled with [[DoorStopper the Backstory of Doom]]) and maximize the amount of damage to the DM's campaign. The end result is a schizophrenic Scotsman with a stuffed parrot on his shoulder he takes advice from that is constantly high and acting erratically... who is also an experienced gunman who can level a church full of cultists "with the speed and brutality of the fucking Spetsnaz", has access and know-how to operate massive amounts of explosives, and is willing to cause ''any'' amount of collateral damage to end his enemies, even if it means crashing a flaming tanker truck into a cult meeting with two of his teammates still inside.
