Beware The Nice Ones: Western Animation
Even SpongeBob has his limits!
- Princess Bubblegum in Adventure Time. As Ricardio found out, hurting Finn, Jake, AND Lady Rainicorn is a quick way to get your ass handed to you, even if you technically have no ass.
- The Galaxy Rangers? Are all heroes. However, Zach has taken starships out of orbit with his Arm Cannon. Niko? Plays like a cross of a Jedi and a Biotic, carries a BFG, and is also very good with unarmed combat. Doc is a Badass Normal in a fight, and manged to take down one of the nastiest villains the show whipped up singlehandedly. Either that or he'll just make every computer in the room riot. Shane was designed as a living weapon. Just get out of the guy's way...Worse is Zozo, who is a short, unassuming alien from an agricultural world and the friendliest, most cheerful guy ever. Piss him off or threaten the folks he's with? Well, he's got an entry under Ambadassador for a reason.
- Francine Smith from American Dad!. She can snap in a rather disturbing manner to the point of being a potential scrappy.
- The quiet, and usually introverted Fern from Arthur has shown a willingness to take (non-violent) revenge on those who mock her, as the episodes "Draw!" and "War of the Worms" can attest.
- Aang, from Avatar: The Last Airbender, is this goofy little kid, okay? He's a monk, he loves riding animals and dropping pudding cakes on fuddy-duddy heads, and playing with kids and generally being the most sickeningly sweet person he possibly can. He can fight pretty darn well, but always goes for disarms or knockdowns... until you cross the Moral Event Horizon in his presence. Then his eyes start glowing and he becomes a demigod capable of throwing hurricanes, tidal waves and mountain ranges around like softballs. He is so terrifyingly powerful and destructive he scares the crap out his enemies, innocent bystanders, his friends and even himself. At this point, just stop moving and silently await your doom. There's not much else you can do. Apart from crapping your pants, but you've probably done that already.
- And tearing up mountain ranges or redirecting rivers isn't even the really scary thing. The worst bit? He can and will rip out your soul (not literally, but getting debended permanently has been referred to as something of the same effect), and there's nothing anyone can do to stop him.
- Aang's True Companions aren't too shabby either. Katara, his cuddly, adorable Love Interest, always loving and nurturing, a true Team Mom to her very core, can blast you through a wall with cupful of water and perhaps turn you into an ice cube in the process. Piss her off enough and she can bend the blood in your veins. Sokka, the epitome of Plucky Comic Relief, also happens to be a swordfighting prodigy, a brilliant tactician, and a genius inventor. Toph may not be as nice, but is really kind when you get to know her. Even still, remember that she's not just boasting when she claims to be the greatest Earthbender in the world.
- Iroh is genuinely a lovable, good humored old man, who loves nothing more than a Spot of Tea and board games... and also one of the greatest strategists, tacticians, warriors, and firebenders in the world. Admiral Zhao learns this the hard way.
- Ursa is a gentle, elegant lady who has probably never hurt a fly. But threaten her kids and she will kill you; there's a reason the trope is called Mama Bear.
- Hei Bai is a kind forest spirit—after all, who would fear an entity who takes the form of a panda? Messing with his forest is still a bad idea.
- Ty Lee. She cartwheels, she giggles, she flips around her cute ponytail, she takes out your bending and the movement of your limbs with a few well-placed pokes. She only needs about four or five seconds in a fight with an unwitting opponent and she will kick ass.
- Arguably , Monk Gyatso, an Airbender who taught Aang and acted as a father figure to him at the Southern Air Temple. He was lighthearted old man who enjoyed training Aang and always made sure there were time for fun and games. Early in the series, Aang finds his skeleton, surrounded by numerous skeletons in Fire Nation armor, which makes it very clear Monk Gyatso killed them. Keep in mind that not only is Gyatso an elderly man in a tribe of pacifists, but that Airbending is probably the least lethal of any bending , and that the Fire Nation soldiers, at the time of their death, were also being powered by Sozin's Comet, boosting their power exponentially.
- Ant-Man is The Avengers: Earth's Mightiest Heroes' team pacifist, and will continue trying to negotiate a peaceful end to a confrontation well past the end of his teammates' patience. Unless the bad guys he's trying to talk down hurt The Wasp. Then they will get owned.
- Gwen Tennyson and Grandpa Max Tennyson in Ben 10: Alien Force, besides the obvious fact that Grandpa Max is a Badass Normal, he's super, super nice to everyone, but when you push his buttons it's not pretty. Same with Gwen, she's the nicest of the Power Trio, but when she blows up, THINGS BLOW UP WITH HER. (Obvious example: "Max Out")
- Gentle Giant Modo from Biker Mice from Mars. He's basically one of the nicest characters on Biker Mice, but it's a very bad idea to provoke him by calling him a rat or threatening his bike.
- Camp Lazlo: Be very afraid if you ever manage to push Extreme Doormat Slinkman to his breaking point, as happened in "Squirrel Scout Slinkman".
- Gi from Captain Planet and the Planeteers is usually the Team Mom and peacemaker who tries to see the good in all humans. She also tried to drown someone when she found out he shot her good friend, and it's hinted that when they went undercover to find guns she was going to shoot him. You wouldn't like her when she's angry.
- Ma-Ti is the trope namer for What Kind of Lame Power Is Heart, Anyway?, but that's only because he's so kind he never had the heart (hah) to use it to its full potential. Gaia said Heart was the most powerful of the five for a reason, which is displayed in detail anytime Ma-Ti decides to get serious.
- Seemingly invoked on Casper in one of the older cartoons, Fright from Wrong, when his nasty uncles force-feed him a huge jar of "Mean Pills" that practically warp him into a red devil creature. Naturally, this backfires when Casper spends the rest of the short putting them through the wringer (both literally and figuratively). It would appear that this example wouldn't count since Casper was drugged to act like that, right? Ehhh, not so much... he reveals at the very end that he never took the pills; all the cartoonish brutality he'd unleashed on his uncles was all him just trying to teach them a lesson! The little Friendly Ghost really can be scarier than given credit for.
- In a Celebrity Deathmatch between Tom Hanks and Sean Penn, Hanks, nice guy that he is, doesn't put up any sort of a fight. It is only after Penn attacks an innocent photographer that Hanks really gets into the Deathmatch spirit.
- When he has his personality swapped with that of Genghis Khan, Gandhi proves that he is quite an impressive fighter.
- David Spade gets pummelled for most of the fight, right up until he slingshots a baseball through Steven Seagal's brain.
- Mandy Moore is sickeningly sweet at the start, even crying to the referee that Pink is being mean to her when she gets hit in the face. But when Pink calls her a 3rd-rate Britney wannabe, she goes totally bananas and nearly stabs her to death with a lollipop.
- When he gets riled up, Garth Brooks manages to subdue Marilyn Manson. Had his banjo not broke, he might have even been able to kill him.
- A sort of weird example with Steve Irwin where he does manage to kill Medusa, but it's totally by accident, and he wasn't actually interested in fighting her to begin with, just educating people about her existence.
- Keith Flint finds out the hard way when he interfere with a certain Canadian while she was singing only to discover what happens when messing with her. To be fair, it was unlikely on her free will through because Zatar the Alien had took over her or clear if it's was really her.
- Gadget from Chip 'n Dale Rescue Rangers snaps twice: in "The Case of the Cola Cult" when her friends are endangered and her inventions are sabotaged and, in "Dirty Rotten Diapers", when her repeated attempts to solve the situation peacefully are met with nothing but extreme hostility and violence from the subject in question.
- Even more to the point is nice guy and all around fun loving Dale, who upon losing his memory becomes for all intents and purposes the Chipmunk equivalent of Rambo.
- Most of the time Kuki/Numbuh 3 from Codename: Kids Next Door is the team's sweet ditzy Genki Girl, but when she does get angry, epic asskicking usually ensues.
Mr. Boss: Quick! RUN LIKE LITTLE GIRLS!
- Sonya/Numbuh 83 is also the most timid out of Sector W. Unfortunately, many villains foolishly choose to threaten locking her and her teammates in a dark cell which instantly erases the timidness, and replaces it with a raging beast that even Satan would fear,
- Arguably, Jack Fenton from Danny Phantom. Often the Bumbling Dad, he retains an optimistic, jolly attitude. But when his loved ones are threatened, he turns into a straightforward Badass Normal and then his victims are in for a world of hurt.
- Jack? JACK? No no no no no. MADDIE.
- Danny himself applies; he's normally a laid-back, friendly kid... when he's human. It's when he's not that you really have to watch out for, as numerous lesser foes found out... as did Vlad, if in another future.
- Dexter's Laboratory:
- You do not want to see Dexter's father angry. Same with his mother.
"Did you say... snowballs?"
- And God help you if you make Dee Dee seriously angry.
- Lampshaded on Dragons: Riders of Berk by Bucket and Mulch after they see Fishlegs lecture Snotlout into returning a stolen dragon egg.
Mulch: It's always the quiet ones that snap the loudest.
- In the Droopy Dog cartoons, the title character is a stoic and monotone character unfazed by any problem. However, if you do something truly petty in cruelty (especially to "The Dame"), he will walk up to you and note in the same monotone, "you know what? That makes me mad." Then he proceeds to demolish you with the same dispassion as before.
- The strong but good-natured Ed in Ed, Edd n Eddy is normally a Gentle Giant who doesn't even get mad when his bossy kid sister Sarah (AKA the "rotten-to-the-core cherished one") abuses his trust. But when he's in a bad mood in the episode "Little Ed Blue", even SARAH is intimidated by him:
Sarah: You can't kick me out, I live here too!
Ed: So move!
- This applies to Jimmy in a few episodes. The first one it appears in has him pulling off an extremely complex (and cruel) scheme as revenge against the Eds, all because Eddy gave him a wedgie.
- In the Picture Show, Edd finally snaps after a mean prank is pulled on him. Ed is terrified, while Eddy goes from nonplussed to breaking down in tears.
- Not only that; Edd chews out Eddy for leading them nowhere and being mean to him, and throws him in a fight. And this is coming from a guy who "can't lift a butterfly".
- In one episode, Edd manages to do this completely by accident, due to a series of accidents and misunderstanding that kept resulting in someone getting hurt. It took a Beware the Nice Ones moment on Jimmy's part to put an end to it.
- In Family Guy, Meg Griffin has been described by Brian as "far sweeter and kinder than the typical American girl" and has put up with a LOT of abuse these past couple of years. However under the right circumstances, Meg could unleash her repressed rage on anyone that pisses her off enough or have prison life turn her into hardened badass that her whole family is DEATHLY afraid of.
- Stewie also qualifies. Heís been a Nice Guy in the new seasons, but donít piss him off if you know whatís good for you.
- Joe too.
- Fry was all mellow while he was fighting with Zoidberg to the death. But when Zoidberg cut his arm off, he screamed "You BASTARD!!! I'll kill you! YOU BASTARD!!!"
- Nibbler was also on the receiving end of Fry's wrath when Fry discovered that Nibbler was responsible for Fry's cryogenic freezing back in the year 2000.
Nibbler: Why are you choking me?
- Penny Ling from Littlest Pet Shop (2012). She's kind, sweet, gentle, sensitive, and painfully adorable. One forgets that despite all that, as a panda, she's a bear at their own risk — she's easily the strongest of the pets physically and the most intimidating when she has cause to be, and even Vinnie thinks better of crossing her on the rare occasions she actually gets angry.
- There's also Sunil, the nicest pet beside Penny Ling, who turns from a Lovable Coward into what can be best described as an action hero when confronted with his Berserk Button, cobras.
- Princess Katherine, from Disney's Gargoyles series, started out as a brat but ended up essentially giving up her whole world to protect the orphaned gargoyle eggs. Then, when Demona and Macbeth end up attacking the young gargoyles, Katherine grabs Demona's laser-rifle and knocks her out. To repeat, she beat Demona in a fight, with a weapon she'd never seen before that night, when she's never been seen fighting on-screen before. Everyone is very impressed.
- Zilla Jr. in Godzilla: The Series is usually content with just lazing about eating fish and swimming in the ocean all day. Harm his "father", Nick Tatapolous, however? Run.
- PJ of Goof Troop is a Nice Guy and his friend Max and father Pete take advantage of him constantly. But sometimes people can push him just too far. In "And Baby Makes Three", after being treated like a "feudal serf", he gets back at Pete while dressed as a baby, biting him and deliberately breaking the rules that would upset him the most (because babies don't know any better). He goes through with an extremely passive-aggressive payback for another time, "From Air to Eternity", when Pete lies to him about his fear of heights and makes PJ feel guilty for lying (even though he didn't) and being afraid of heights himself, going out of his way to coerce a confession out of Pete while acting as if he were in life-threatening danger (one of the few things that actually worries Pete). And in "Queasy Rider", when Max was considering how he would become cool and said he wouldn't forget PJ afterwards in a condescending manner, PJ pulled an overflowing hose trick on Max.
- Sweet, innocent, adorable little Ding-A-Ling Wolf from the Hanna-Barbera Hokey Wolf cartoons. One time he beat the living crap out of a Killer Robot with a HUGE CLUB because the robot was strangling Hokey.
- "Pepper" Potts from Iron Man: Armored Adventures. That's probably one of her trademark aspects of her personality (aside from her Motor Mouth that is.) Nomrally, this girl is goofy, bubbly, and talkative, but if the situation calls for it, she shows a somewhat violent side of her. An example of this is when she mentions offhand to Gene that she got a guy deported for espionage. When the armor designs are stolen and sold to Stane and Hammer, Pepper suggests Tony steal them back or trash their companies trying amidst various angry growls.
- GIR of Invader Zim, though more selfish and self-centred than most examples, is a sweet Genki Guy of a robot with an obsession for fast food and small animals, but when in "duty mode", he becomes a frighteningly efficient minion of The Empire. Mercifully, it usually only lasts for a few seconds, but on the one occasion he was locked in this mode not only did GIR accomplish more in ten minutes than Zim had over the entire series, it almost killed him.
- Dukey from Johnny Test can kick serious butt if pushed too far. After all, he destroyed a FRIDGE with a flying kick in one episode.
- Mitsuki from Kappa Mikey is generally good-natured and level-headed to the point of ridiculousness, given what goes on around her every episode. But she can be shockingly devious when the situation warrants it, and she knows her castmates frighteningly well. So far, only Lily and Gonard have been unfortunate enough to provoke her ire. Unusually for this trope, she got her revenge without resorting to violence... in one episode, Lily's computerized vanity put a pretty big bull's-eye on her head, and in another, Gonard's faked-injury ploy was easily turned against him.
- It should be noted that Mitsuki is a retired spy and knows such things as how to kill a person with one touch. She shows off her bad side more effectively in the episode where the guy in the mailbox suit tries to get her to re-join the agency.
- Ron Stoppable in Kim Possible. He's a generic goofy sidekick that mostly gladly acts as a distraction, but if you get him pissed of by either hurting Kim or boasting about destroying Bueno Nacho he gets in such a Mystical Monkey Rage that he will kick your ass. On the occasions that he goes evil even Shego is afraid, and the only major villains on the show to have been Killed Off for Real are Warhok and Warmonga. Why? They threatened to kill Kim, and keep her corpse as a trophy in front of Ron. Do that, and you're in REAL trouble.
- Kim herself is usually pretty pleasant even to her villains, joking good-naturedly as she rounds them up again. But push her too far and... well, it's not pretty, as Bonnie, Drakken, and Shego have all found out.
- From The Legend of Korra, we have:
- Jinora, Ikki, and Meelo, Tenzin's Airbender children. They start out as really sweet kids, if a bit annoying, until "Turning The Tides". Simply put, when Amon and his forces tries to invade Air Temple Island, the kids combine The Cavalry, Big Damn Heroes, and Let's Get Dangerous all in one Crowning Moment of Awesome to protect Lin and Air Temple Island from Amon's second-in-command, the Lieutenant, and a shitload of Equalists.
- Asami looks and acts like the high-class lady she is, but piss her off and you'll find out why her father had her learn martial arts at a very young age. She also has Sokka's technological gift behind her, and thanks to her father's corporation she can almost instantly learn how to pilot anything in the series. Hiroshi is the villainous example from the family, as he is possibly the most supporting father anyone can wish for, but beneath all that lies a vengeful and hate-filled soul that will even go as far as to kill his own child to get his revenge.
- Suyin is the supportive and kindhearted matriarch of Zaofu, proving to be a great ally to Korra and her friends. Even when confronted with Lin's escalating antagonism, she still keeps a level head and is willing to mend bridges with her. But when someone betrays her trust or threatens her family, Su shows no mercy and is almost eager to see them suffer.
- Looney Tunes: "Of course you realize, this means war!". Practically it was the case with the whole cast, but Bugs Bunny made it his catch phrase.
- Porky Pig, in The Looney Tunes Show is an Extreme Doormat, letting most people, especially Daffy, take advantage of his nice-guy persona. Even going so far as to give Daffy all of his money so Daffy could have a kidney transplant. But when Bugs revealed to Porky that Daffy lied and used all the money to buy a yacht, an enraged Porky beat the ever-living crap out of him.
- The Many Adventures of Winnie the Pooh: The sign on Piglet's house that reads "Trespasers Will Be Shot!!!" To be fair, the house belonged to his grandfather (Piglet assumes, due to Signs of Disrepair, that Trespassers Will is his grandfather's name), but assuming Piglet's family has the same disposition as him, it's still rather surprising.
- Megas XLR. Coop is a nice, easygoing guy who enjoys all things food. Threaten his friends, insult his robot, or deny him a Megaslush, and he becomes an outright berserker. Pretty much every villain was stupid enough to hit at least one.
- In one episode of Metalocalypse, Toki Wartooth had been pestered by a fan who kept shouting in his face during a show. He grew infuriated and pummeled (possibly even killed) the guy to no end. Even Murderface, who was going to kill him for taking his domain page name, quickly changed his mind.
- This was foreshadowed in Dethdad. Senator Stampington explains Toki's pent-up aggression and flat out says "Toki Wartooth will kill us all."
- The primal example: Mickey Mouse, though the classic nice guy and often rather hapless in gag situations, is nevertheless a force to be reckoned with when pushed too far. Even today in Kingdom Hearts he's a dynamic fighter in dramatic situations. Originally, the entire point was that you didn't expect to see a lovable guy like Mickey in a battle royale, so the sight on its own was funny.
- In the older cartoons, before he gets significantly watered down to The Generic Guy of the group, he's just as aggressive as Donald Duck when pushed to the limit - such as in the 1942 short "Symphony Hour", where he ultimately pulls a pistol(!)◊ on Donald when the duck tries to skip out on a concert Gone Horribly Wrong. Notably this is the last time until House of Mouse we see this side of the mouse.
- How about in Fantasia, where the innocent Sorcerer's Apprentice brings his broom to life, finds that it is doing its job a little too well, and attempts to rectify the situation... by brutally chopping it to smithereens with an axe. We only see their shadows on the wall...
- In Donald's Better Self, Donald's shoulder angel may be resistant to fighting at first, but as his shoulder devil learns the hard way, even he has his limits.
- Posey in Mission Hill may be the resident pacifist and airy Granola Girl, but she can be made rather sadistic when insulted and her friends threatened. Read the exchange quote in this articles' Quotes page.
- My Life as a Teenage Robot: X-J9, aka Jenny is very sweet and prefers to live like a normal teenager instead of save the world. She even ignores (mostly) the school Alpha Bitches who constantly try to ruin her. But underneath that is a robot with tons of weaponry that can take on an entire alien invasion, so don't threaten her, her friends, or the human race.
- My Little Pony: Friendship Is Magic:
- Fluttershy is the nicest character around — too nice, in fact, timid and prone to let others push her around. She almost never gets angry... and you'll already have guessed this entry is about those times that necessitate the "almost" in that sentence. Hurting or threatening her friends can make her angry enough to forget to be afraid and instead bring out a will strong enough for Staring Down Cthulhu. At least then she's still being good, just extremely stern. But a momentary nervous breakdown she suffers in one episode when her ability to befriend animals inexplicably fails causes her to snap and go berserk hunting the animals. ("You are going to LOVE ME!") And bad assertiveness training in another episode turns her temporarily into a highly effective bully. This is ironic in itself because she could already at best be genuinely assertive enough to make a dragon stop attacking and start crying just by talking to it, and it makes perfect sense when you see it.
- Normally, Princess Celestia is very calm and collected, and seems to enjoy having a little fun with her subjects now and then. Then we have the first part of "The Return of Harmony", where she smacks the villain with a Shut Up, Hannibal! TWICE, and then tells him point-blank to quit screwing around and answer her questions. He begrudgingly tosses out a riddle and leaves before she can grill him any further. It's one of the few times she's ever been seen not only genuinely angry but faced with someone who outright defies her and seemingly gets away with it.
- In the season two finale we finally see Celestia fight, complete with Pre-Asskicking One-Liner. True, she loses, but that surprised EVERYONE, including the villain.
- In the Season 3 opening episode, we see Twilight entering the main room of the Canterlot Castle, only to find a very pissed off Celestia, going as far to practically bring Twilight Sparkle to TEARS!! Granted, it's just Sombra's dark spell creating an illusion, but still... assuming that's how she really sounds when angry, it makes you want to NOT anger the Demigod in the first place!
Princess Celestia: It doesn't matter to me, *face turns to Twilight, angered* you FAILED the test, Twilight!
- Flashbacks of Celestia in the Season 4 opener also show a few of the other times in her past where she's had no other option to deal with rampaging magical beings except to (sometimes reluctantly) fight them, a reminder that she's the ruler of Equestria for a darn good reason.
- Twilight Sparkle is the poster mare for Adorkable and No Social Skills, whose passion for knowledge is only challenged by her desire to be a good friend. She's also the most powerful unicorn in Equestria with an incredible well of magic at her disposal, and is entirely capable of unleashing the hurt on anypony she desires. "Lesson Zero" even shows that she's just as capable of sowing chaos and disharmony as Discord.
- You'd think that the perpetually cheerful Genki Girl with borderline Reality Warper powers would be an excellent candidate for this trope, but Pinkie Pie repeatedly subverts it. In "Griffon the Brush Off", her reaction to proof that Gilda is a grade-A jerkface is to throw her a party, because she thinks Gilda is just stressed and needs to unwind. In "Party of One", when she thinks her friends have abandoned her she avoids them altogether and throws her own party with various Companion Cubes, in stark contrast to the far more destructive Sanity Slippages of Fluttershy and Twilight. And when Applejack breaks a Pinkie Promise in "The Last Roundup" she breaks out the scary voice, leads a pursuit across the desert, and when she finally catches her she... demands Applejack apologize.
- Princess Cadance (the real one) is a kind and sweet Love Goddess and used to work as a babysitter. However, when she is kidnapped and her husband-to-be is about to marry her evil double, she shows nothing but determination, repeatedly defies the changeling queen (even after said queen defeats Princess Celestia), and then helps deliver the Heart Beatdown that blows the changelings across the continent!
- Then in the season 3 opener she maintains a field of light and love around the Crystal Empire that manages to keep King Sombra, a unicorn Evil Overlord that took both her aunts to defeat the first time, out for what was likely days. This, combined with his horrific treatment of his subjects, leads to her setting up another love-powered Wave Motion Gun and telling his subjects Do with Him as You Will. The end result is King Sombra being obliterated.
- Rarity is Element of Generosity, an empathetic and helpful friend, and The Fashionista (and a Drama Queen and Large Ham besides) with some rather stereotypically girly/princess-y behavior, but she has been seen spin-kicking Applejack, far and away the strongest of the Mane Six, uppercutting Changelings, and bodily threatening adolescent dragons who dare to threaten Spike.
- Twilight's Kingdom Part 2:
Twilight goes absolutely berserk when Tirek destroys her home, unloading on him with everything she's got.
When you get down to it, Tirek's final fate is to get blasted to hell.
- Phineas and Ferb: "GET ON THE TRIKE!" Note: Phineas does this after trying to reason with Candace.
- When the usually sweet Bubbles of The Powerpuff Girls is sufficiently provoked, she's been shown to eclipse both of her sisters Blossom and Buttercup in terms of raw anger and violence. Every single one of her emotions is taken to the extreme: When she's happy, she's bursting with euphoria, when she's sad, she loses all will to live, when she's afraid, she's paralyzed by fear. So, naturally, when she's angry, she is rage incarnate. Mojo Jojo learned this last one the hard way...
- The Professor also counts. Heís a nice, laid back guy, but if you know whatís good for you, DONíT harm his girls.
- Thereís also Ms. Bellum, a calm secretary, who ends up beating Sedusa in a fight!
- Marge, the endless suffering matriarch of The Simpsons family, has snapped on a few occasions when Homer screwed up once too many (especially in The Movie).
: ...And if you really tick me off, I'm gonna run you down with my car.
- In one of the Halloween Specials Flanders was Satan. In his own words, "It's always the one you least suspect."
- South Park.
- Butters. Stan's exploiting of his grandmother's bullying of him in "Butterballs" eventually causes him to punch out Dr. Oz on national television.
- As proven in Season 1 - Don't fuck with Wendy Testaburger!
- Pip when called "French" in "Conjoined Fetus Lady".
- In the series finale of both Superman: The Animated Series and Justice League Unlimited, Superman (see the comics section) encounters situations that stretch even his patience. In TAS, after taking some of it out on a few humans (some more deserving of it than others), he goes into Unstoppable Rage mode on the cause of it all. In Justice League, he finds it an excuse to cut loose on an extremely powerful foe - the same one who pushed him over the edge last time, in fact - all the while ranting about how nice it is to let go of his inhibitions when he normally has to be so careful, because as far he's concerned the world might as well be cardboard.
- The episodes featuring the Justice Lords provide a pretty terrifying example of what happens when Luthor pushes Superman too far.
- Superman turns into this in Superman/Batman: Public Enemies when Batman sacrifices himself to manually steer a rocket into a kryptonite asteroid (but not really). Superman utters the line "That's my best friend, and you just killed him." before tearing into Lex. Judging by the look on Luthor's face after the monologue, it's reasonable to believe that he just planted the last of his bravery in his underwear.
- The Flash gets his own shot at this too. The next time you start thinking that he doesn't extend much beyond being the goofy, flirtatious, practical joker of the League, just remember that this is the man who can make you explode with his bare hands or rip you to pieces by circumnavigating the globe and coming back to smack you one. On one occasion when Lex Luthor and Flash had their brains swapped Luthor had absolutely no reservations about using Flash's powers to their full extent - and runs highly destructive circles around the entire League as they're trying to capture him. Flash doesn't use a couple of his abilities for a good reason.
- And even earlier than that, in the episode "Secret Society", shortly after the League temporarily disbands on bad terms, Flash is trying unsuccessfully to find the location of his personal villain, The Shade. He tries to interrogate several of Shade's known henchmen, with no luck. It culminates in him attempting to intimidate one thug by dangling him over the edge of a rooftop by his legs. Of course, the thug isn't intimidated and even mocks Flash's attempt at a Batman-style interrogation... but by this point Flash is utterly fed up (though his face doesn't show it).
Look, I know Batman. I once ratted out a counterfeiter to Batman. And believe me, you are no Batm— (Flash drops him) aaaAAAAAAAAHHHHHHHHHHH
- The Spectacular Spider Man: Otto Octavius. Kind, apologetic and shy. Fantasizes about killing his boss, Norman Osborn. Then after his big snap, he manages to at least slam him around a bit. Surprising that Norman hasn't become a recluse after all the incidents with insane coworkers he's had.
- The whole "Otto Octavius became Doctor Octopus because he was pushed too far" thing was also used in Spider-Man 2, in one of Alfred Molina's best performances.
- The title character of SpongeBob SquarePants is extremely tolerant and obnoxiously optimistic. Though, in one episode Squidward resigns from his job and ends up homeless as a result. SpongeBob finds him and takes him into his home until he can find a new job. He takes it too far and stays a lot longer than necessary, turning SpongeBob into his personal slave (even forcing him to wear a maid's uniform). While SpongeBob doesn't completely lose his temper, he snaps a bit and drops some very obvious hints that Squidward should go look for a job already. The latter refuses to take said hints, though, so SpongeBob furiously takes Squidward, still in bed, all the way to the Krusty Krab. He tries to convince Mr. Krabs to hire Squidward back, and when that didn't work, the sponge finally snaps, outright strangles his boss, calls him a cheapskate, and finally yells at him on how stupid the situation is. It shows that even SpongeBob has his limits...
- In "Krusty Love", after Mr. Krabs has alternated between demanding very expensive gifts for Mrs. Puff and berating him for spending so much money, SpongeBob snaps and rants at Krabs for a bit using some apparently-colorful language. Mrs. Puff acts shocked and has to look up a word, and when he finally storms off Krabs is left with jaw inches from the ground.
- Mrs. Puff in "Demolition Doofus" where after SpongeBob punctures her inflation sac, she tries to murder him (no joke).
- Puffy Fluffy. Do not put him in a house with another pet.
- In DC Showcase: Superman/Shazam!: The Return of Black Adam, Black Adam learned that even though Captain Marvel is the ultimate nice guy boyscout (even compared to Superman), presenting him a Sadistic Choice and then trying to kill the hostage anyway is a BAD IDEA. It doesn't matter how experienced or powerful you are, you WILL get your butt kicked. SOUNDLY.
- In the TaleSpin episode "In Search of Ancient Blunders", Adventurer Archaeologist Myra is as friendly and polite as you could hope—but she has her limits. After she, Baloo and Wildcat spend a day being chased around a pyramid by the Air Pirates (who want to loot it) and a mummy (who wants to protect it), Myra finally loses her temper and yells at the mummy: "We're trying to help you! You can stomp around all day growling like an idiot, or you can give us a hand!" The mummy takes Myra's advice and gets rid of the Air Pirates.
- In Teen Titans, lovable and quirky Beast Boy, who usually runs away from anyone powerful and evil, when sufficiently provoked is quick to bring the pain. All of which are surpassed by the penultimate episode of Season 5 (which starts off with his growling "NOW try and follow me!" and blowing up some fallen robots, right after the Brain is done gloating over his victory over all the other Titans), in which Beast Boy assembles a rag-tag team, leads it properly, and takes on all of the show's villains at the same time. He closes it by quipping "Brain Freeze", after freezing the Brain.
- When Starfire drops her usual sweet, gentle, Friend to All Living Things persona and goes into full on Tamaranian battle mode, ass-kicking will ensue. In her chronological first appearance she is captured by the Gordanians as a slave/trophy, and breaks out so fiercely she leaves her captors terrified, going on a rampage in Jump City where she fights evenly with the other Titans. All while being shackled and prevented from using her full powers. Heck, the main reason the Teen Titans formed in the first place was to get her to calm down!
- Raven, who while more cynical, is generally a fairly reserved person. God help you if you piss her off, though, because it's her careful control that keeps her from going One-Winged Angel. As both Slade and Dr. Light can attest, an angry Raven is terrifying, not to mention lethal. Season 4 shows that Raven is more powerful than all four of her teammates combined under the right circumstances.
- Terra is a cute, big-eyed teenager who likes joking and goofing around. She can also be extremely violent and a Woobie, Destroyer of Worlds when provoked.
- Anet from ThunderCats (2011) is a Forgetful Jones Elephant monk, kind natured and peaceable, who, like the rest of his Village, is more prone to meditating on a problem than taking direct action. When their village is invaded by Lizard Folk, the dire straights prompt a collective Awakening the Sleeping Giant, and Anet in particular leads the charge. He tosses one of the invading force's Walking Tanks into its neighbor, and makes short work of the Lizard general's bayonetted rifle, wrenching it out of his hands and bending it in half. In response, the general flees in terror.
- Tintin's Professor Calculus is normally a soft-spoken, mildly eccentric, rather charming old man, who, by virtue of his poor hearing and generally good demeanor, does not notice most of the jokes at his expense, and doesn't care about those he does hear. But then Captain Haddock accused him of "acting the goat"...
- In the comic at least, his rant at Captain Haddock lasts for several pages, and includes shouting that he is not the Cloud Cuckoo Lander that everyone believed him to be. It ends when he shows Captain Haddock the nuclear powered rocket as big as a skyscraper which he designed and built.
Calculus: See what "the goat" CREATED!
- Shirley the Loon of Tiny Toon Adventures is the very model of serenity and inner peace, but when a plan for her and the other girls to abscond to the prom of a rival school ends with Miss Loon doused in punch, she snaps, in an obvious nod to Carrie.
- In another episode, Shirley is driven to distraction by Plucky when he wants her to channel a genius into him to help him ace a math test he didn't study for. She ends up finally snapping and killing him with kindness by channelling Albert Einstein. It seems that Einstein wasn't that good at math...
- Part of "Phone Call from the 405" had normally adorable and chipper Sneezer briefly chew out Buster and Babs for having him calm down an angry Steven Spielberg over the phone.
- On Total Drama Island, Beth and Lindsay spend a good deal of the season under Heather's heel, which makes these instances all the more satisfying. First, Beth finally realizes that she's serving someone she hates, and as a result drops the challenge and begins shooting her with her paintball gun. Then, much later, after Heather pretty much tosses Lindsay aside despite total loyalty, she responds by cussing her out, much to Heather's shock (and everyone else's approval).
- Harold took a lot of torment from Duncan over the course of the first season. When Duncan's love interest is suddenly an inexplicably voted off, the end of the episode reveals it was because Harold cheated to switch the votes.
- In "Greece's Pieces": Dogged Nice Guy Cody has been trying to get Gwen's attention for about three seasons. Instead, Gwen wound up kissing Duncan, even though he was still dating Gwen's friend(ish) Courtney. Cody had a slight Heroic BSOD after finding out, during which Duncan showed up, unaware what was going on. Then he insulted Cody's outfit. Then Cody knocked him out in one punch. Can be found here.
- In Revenge of the Island, Zoey is this trope personified, undergoing a Madness Makeover and a drastic change in personality in "Eat, Puke, and Be Wary" after being pushed too far. Fortunately, the personality change does not last long.
- This even happens to Mike and Cameron when pushed too far.
- Rhinox, from Transformers: Beast Wars is of the standard Gentle Giant variety. Once something does get through his skin, he's a raging mass of strength and firepower that even Proud Warrior Race Guy Dinobot has learned to tread lightly around.
- That chapter where the Predacons capture him and make him evil. Destrucity ensues.
- This is taken further in Beast Machines when Rhinox was turned into the Tankor, the Tank Drone General and lost his morality even after regaining his spark. He alone became a creditable threat to both Optimus AND Megatron, the former having a band of elite soldiers while the latter has the entire planet under his control. It says a lot about the Maximal's former chief scientist
- Primus help you if you even think of hurting Blackarachnia. Even if you can lay a hand on her, she's got Silverbolt, her Knight in Shining Armor who breathes this trope, and will make you regret touching the "dark poison of his heart."
- Optimus. He'd rather not fight, even trying to reason with Megatron ("Why start this up again?"). Sufficiently pushed, he becomes a determinator who will forcefully remind you that he is a Prime. (well, Primal. Same thing)
- Tigatron, the resident Friend to All Living Things... who will make you regret it if you threaten to harm nature, like Inferno learned.
- In Transformers Animated, we've got Bulkhead. Usually a Gentle Giant, though very good in battle, but if he even thinks you hurt his human friend Sari, prepare for a beatdown.
- Sari, especially after she upgrades in season 3. Even before that she managed to scare off the Constructicons with nothing more than herself and a pair of roller skates.
- Bulkhead's Transformers Prime counterpart is just as nice off-duty. But when he goes to war..., well,there's a reason he was part of the Wreckers, one of the most Badass Autobot combat units in multiple continuities. This is exemplified in one episode where he tries to tell his Human friend Miko to look away, right before he proceeds to tear out a Vehicon's spark.
- It's very, very hard to make Optimus legitimately angry at you. This is a good thing for everyone involved.
- Bumblebee is usually a very friendly and sweet character. However, when Megatron nearly killed Raf, Bumblebee's Berserk Button was pressed and he would have shot and attacked the former if Arcee and Bulkhead didn't hold him back.
- In the Prime finale, Bumblebee kills Megatron!. Beware the nice one indeed.
- The ORIGINAL Optimus Prime from Transformers Generation 1. A Father to His Men, and a kind-sparked Gentle Giant...up until someone pushes him too far, then he demonstrates just WHY he is the leader of the Autobots.
- The Venture Bros.: Do not be rude to Triana Orpheus in the presence of Dean Venture. He may throw sissy punches, but he'll throw a lot of them, and he won't give you any warning first.
- Dr. Orpheus, for all his melodramatic flair, is generally a decent guy. Loving father, good friend to the Venture Family and, of all the people seen in the show, the most genuinely heroic. HOWEVER: Push him too far and you'll pay for it. As "TWO FOUL-MOUTHED REDNECKS!" learned to their regret.
- Doug, the adorable and pitiful Koala-Man from Ugly Americans who cries Once an Episode, was revealed in one episode to be a former international assassin.
- Nabu from Winx Club is usually a nice person, but during S4 episode 24, after the evil shapeshifter Duman turns into a monster and reveals that the Black Circle lied about their apparent Heel-Face Turn and that they are really planning to seal the Earth fairies away for good, Nabu proceeds to single-handedly defeat Duman, by trapping him inside a magical sphere which then explodes. Brandon even comments on this afterwards:
Brandon: Hey, remind me never to make you angry!
- This seems typical of all fairies. Sure, they're nice most of the time, with them being all about love. The first time Bloom got angry, she chased away the Trix and a couple dozens witches. At times Tecna is positively murderous, and (in the original version) can't understand the concept of fighting another day. And while the Earth Fairies are very nice when calm, when furious they become The Fair Folk, genocidal tendencies included.
- Regarding the Winx, this especially goes for Flora, who dislikes fighting of any kind, has few offensive attacks and literally feels pain when nature is destroyed. Don't call her pathetic and do not hurt her little sister!
- Hay Lin from W.I.T.C.H. is a bubbly Genki Girl who is generally the least violent of the Guardians. But when Nerissa stuck her crush Eric on a miniature sun and mocked her about turning him into a charcoal briquette, she snaps out of her Heroic BSOD and throws her across the room, and then proceeds to unleash hell on Nerissa's thralls, all of whom have twice the power she has.
- Matt also counts. He's not even a Badass Normal, but while being possessed by the demon Shagon he fought back hard and made him sweat to keep Matt under control. Matt eventually defeats him in a Battle in the Center of the Mind when he threatened to kill Will. Later episodes had him become one of the Regents of Earth, after which he regained Shagon's powers for himself.
- M'gann from Young Justice is a sweet bubbly girl most of the time. She's also turns out to have Psychic Powers that dwarf those of any other Martian her uncle has ever met. When the villain Psimon threatens to expose her greatest secret—the fact that she's actually a White Martian, not a Green one—she's willing to do anything to stop him—including knocking her own friends unconscious before they can see her, then Mind Raping Psimon into a coma.
Psimon: Now, no, my pretty. I know you don't want to do anything you'll regret.
M'gann: You don't know me AT ALL!
- By season two Mind Rape has become a standard tactic for her, even as her ex-boyfriend Superboy voices his obvious disapproval. This ultimately culminates in her using it on Kaldur, in a rage over his murder of Artemis and kidnapping her boyfriend La'gaan and brother Beast Boy. Which leads to a Heroic BSOD when she realizes he's a double-agent and Artemis is still alive.
