----

* Steele from ''WesternAnimation/{{Balto}}'' seems to be your average animated movie {{Jerkass}} at first--making fun of Balto, flirting with Jenna even though she's not interested, etc etc. All par for the course. But when he refuses to let Balto take the crate of medicine, thus condeming the children who desperately need it to certain death, it becomes clear how horrible he is. And, once he was defeated, he deliberately tried to ensure that Balto and the whole team of dogs got lost and died, while he could return home and pretend to be a heroic survivor.
* Archibald Snatcher in ''WesternAnimation/TheBoxtrolls'' doesn't seem that nasty of a villain and rather a [[LaughablyEvil goofy one at best,]] until later on in a flashback that [[spoiler: He kept Eggs' biological father captive for many years, [[GoMadFromTheIsolation driving him to insanity]] even though the flashback had him intending [[NotSoHarmlessVillain to murder him]] with [[WrenchWhack a wrench.]]]] Even worse, he [[spoiler: knows the whole time that [[OurTrollsAreDifferent the Boxtrolls]] are harmless but lied to the whole town simply so [[SocialClimber he can be a part of the White Hats.]]]] His actions are bad enough to make him be on the list, but near the end [[spoiler: He [[ForcedToWatch forced Eggs]] to watch his adopted family get murdered (they escaped in time, but still), and dressed Eggs up as the last Boxtroll and [[WouldHurtAChild tried to kill him in a furnace]].]] Archibald then [[spoiler:rampages through the square and endangers everyone before abducting Winnie.]]
* [[NoCelebritiesWereHarmed Darla Dimple]] and her servant Max from ''WesternAnimation/CatsDontDance'' crossed it when they sabotaged Danny's chance to impress L.B. Mammoth (or, more specifically, their method of doing so). They do so by flooding the stage with so much water that it practically drowns the entire studio [[FridgeHorror (which, if this were realistic, would have killed lots of people)]], but instead, it sets up Danny and co as incompetent and causes them to abandon the production, less scary and not as bad as the other examples, but still a {{Jerkass}} move.
* [[spoiler:Lord Barkis Bittern]] in ''WesternAnimation/CorpseBride'' crossed the line a long time ago after [[spoiler:he murdered Emily in cold blood to steal her dowry.]]
* In WesternAnimation/TheCurseOfTheWereRabbit, Victor Quartermaine starts out as both Wallace's rival (whose MO is killing rabbits) and smarmy competition for Lady Tottington. But he shows his true colors when he learns [[spoiler: that Wallace is really the Were Rabbit, and is now more determined to [[{{Yandere}} kill him]] so he can have Lady Tottington. ]]
* ''WesternAnimation/HeavyMetal''. During the Harry Canyon segment, the titular character helps an unnamed woman hide from a group of thugs who want the Loc-Nar from her. The following day, Ratnik, the leader, contacts Harry to meet with him at the Statue of Liberty and give the Loc-Nar to him in exchange for a huge sum of money, getting the woman out of danger. And how does the woman thank him? [[spoiler: By pointing a gun at him and demanding the entire amount for herself. The 2 of them previously agreed to split it in half.]]
** Although, the film implies it wasn't entirely her fault. The Loc-Nar is said to corrupt the will of people it interacts with, and bring out the evil potential within them.
* In ''WesternAnimation/HowToTrainYourDragon2'', if it wasn't clear enough by then that Drago Bludvist is 100% morally bankrupt, it most certainly was when [[spoiler:he uses his Alpha to brainwash Toothless into killing Stoick]].
* In ''WesternAnimation/KungFuPanda'', when Tai Lung [[spoiler:confesses to Shifu that all he ever wanted was to make him proud, only to find out that he had Shifu's pride and love all along, he only spends one moment looking genuinely affected before he's right back to demanding the scroll, saying he doesn't care about apologies]]. Since he's basically thrown away any sort of redemption that might have been offered to him, that moment signals that he deserves everything that happens to him afterward.
** At this point Tai Lung probably did not believe that Shifu was sincere (he'd just finished giving him a NoHoldsBarredBeatdown and was going to kill him--ergo, Shifu would say anything to save himself) and was past reasoning with him anyway, Tai's last speech during the battle was only meant to hurt. That's why they made Po offer him a LastSecondChance later.
** In [[WesternAnimation/KungFuPanda2 the second]] Movie, Lord Shen, as far as he appears on the screen, always was a power-hungry murderer, but he really crosses the line when [[spoiler: he massacres an entire panda village.]]
** As if that isn't enough [[spoiler: he coldly kills the Wolf Boss ''just because the Wolf Boss didn't want to murder his own men''.]]
* ''WesternAnimation/LegendOfTheGuardiansTheOwlsOfGaHoole'': Kludd moonblinks his baby sister, which is essentially zombifying her. Seriously, dude, NOT [[{{Pun}} Ka HOOLE!]]
** In the book, he crosses much, much sooner, although Soren/the reader doesn't know it at first. He [[spoiler:shoves Soren out of the nest, hoping it will kill him (his own brother) then does the same to said little sister, and has a hand in his own parents' deaths.]]
* ''WesternAnimation/{{Planes}}'': Ripslinger sending Ned and Zed to sabotage Dusty during the China-Mexico stretch.
* In ''ThePowerpuffGirls'', if you thought that Mojo Jojo was an incompetent and harmless villain in the TV series, be disappointed when you see TheMovie. He arguably crossed it by enslaving Townsville with super monkeys, destroying half the town, and betraying the girls' trust in the process. Confronted with this development, he tries to BreakThemByTalking:
-->'''Mojo:''' Can't you see? None of them will ever understand you the way I can. [[NotSoDifferent For we are kindred spirits whose powers spring from the same source.]] [[DontMakeMeDestroyYou So girls, do not make me destroy you!]] For we are smarter! We are stronger! We are invincible! We have the power! We are superior to them! [[WeCanRuleTogether And we shall rule! All we have to do is work together. Girls, join me.]]\\
'''Girls:''' [[BigNo NOOOOO!]]\\
'''Blossom:''' [[ShutUpHannibal We'd never join you!]] And it's because we are stronger!\\
'''Bubbles:''' Because we are invincible!\\
'''Buttercup:''' Because we have the power!\\
'''Girls:''' Because we've got to protect them from you!\\
'''Blossom:''' It's you who is to be feared!\\
'''Bubbles:''' Because you are a monster!\\
'''Buttercup:''' Because you are evil!\\
'''Girls:''' [[MeaningfulEcho And you are...it!]]\\
''(they push him off the skyscraper where he's standing)''
** Ironically, since the show is set after the movie, this trope is inverted, as Mojo peaked in his evil here and only [[VillainDecay had down to go,]] becoming MORE redeemable rather than less.
* Pharaoh Seti in ''WesternAnimation/ThePrinceOfEgypt'' led a campaign to curb the Hebrew population by rounding up and killing all of their infants. He's not too sorry about it, either, with murals depicting the event adorning the walls of his palace. When Moses, his adopted son, tries to call him out on it, Seti just blows off his concerns, saying "Oh, my son... ''they were only slaves...''" He ''thought this would make his adopted son feel better.'' He was trying to ''comfort'' him with those words. Oops...
* In ''WesternAnimation/SouthParkBiggerLongerAndUncut'' Sheila Broflovski starts out as a WellIntentionedExtremist who works to ban Terrance and Philip's film Asses of Fire, and ultimately all Canadian products to solve the problem of children swearing. Even when she orchestrates the arrest of Terrance and Philip her actions are still understandable, if off the deep end. Finally, when Kyle helps rescue Terrance and Philip from execution and delivers a heartfelt speech to convince her to relent, she snaps and kills Terrance and Philip herself. This leads to an MyGodWhatHaveIDone Moment when Satan tells her that her actions have allowed him to return to conquer earth.
* ''Superman'' in ''WesternAnimation/SupermanVsTheElite'' jumps through the MEH when he decides to finally buy what Manchester Black is selling... by murdering each of the Elite, then lobotomizing Black by destroying his powers. [[spoiler:Then, we find out he ''subverted'' it by revealing none of the Elite are dead, that an army of robots saved them, and that his way ''works''.]]
* The [[WesternAnimation/TeenageMutantNinjaTurtles2003 2003 Shredder]] crossed it in ''TurtlesForever'' when he tries to kill the Turtles Prime while ignoring Karai's warnings that killing them will wipe everyone out of existence, [[RevengeBeforeReason including himself.]] Though then again, he witnessed the entire TMNT Multiverse, which showed countless alternates of himself and the turtles, the turtles winning every time. This drove him completely insane to the point where he considered he had no choice but to wipe out all of those realities, even if it meant killing the other Shredders (Whom he didn't give a crap about anyway)
* Many DisneyAnimatedCanon movies have the main villain cross the horizon at some point - mostly so that even small kids can tell who is the good guy and who is the bad guy, and determine that the bad guy DID deserve a violent death or, at the very least, a thoroughly spectacular form of [[HumiliationConga Abject Humiliation Conga]]. Here are some examples, in chronological order:
** ''Disney/SnowWhiteAndTheSevenDwarfs''. After Snow White has grown up enough for the mirror to declare her more beautiful than the queen, the queen orders her hunter to kill her and bring back her heart as a trophy ([[CrazyPrepared she even already had a box custom-made for the occasion]]). When that doesn't work, it turns out she's studied murder spells as a backup plan. When she learns that the Sleeping Death spell she's put on a certain apple will only leave Snow asleep and can be cured, she isn't fazed but rather ''delighted'' -- because she's sure that the dwarfs will [[BuriedAlive bury Snow alive!]] Snow must have had her hands full as the new Queen - she probably had to sort out some pretty sadistic lawbooks.
** Lady Tremaine from ''Disney/{{Cinderella}}'' is established as a nasty piece of work throughout the film, and her deliberately breaking the glass slipper at the end is particularly cruel enough to be considered a possible candidate for her MEH since she did it purely out of petty [[{{ThePowerOfHate}} hatred]] toward Cinderella (and she also shows no regard for the Grand Duke's life), but she truly seals the deal in the third installment, ''A Twist in Time'', when she [[spoiler:poofs Cinderella in a twisted pumpkin carriage with Lucifer as its human driver, and attempts to get Lucifer to ''kill'' Cinderella (especially heinous because previously, she had been satisfied with simply making her life a living hell). She also has Anastasia posing as Cinderella to fool the prince. If anyone doesn't know, this is rape by association.]] Also, as WebVideo/TheNostalgiaCritic put it:
---->Nostalgia Critic: She had no magical powers, no minions, all she had was complete control over one person's life. And man did she squeeze every last drop out of it.
** Maleficent in ''Disney/SleepingBeauty'' after she condemns Princess Aurora (as a baby no less) to her doom by pricking her finger on a spindle needle on her sixteenth birthday - [[DisproportionateRetribution and all because she wasn't invited to the party]].
*** That, or [[ForTheEvulz just for fun]], with even the not being invited thing as a mere excuse. The movie leaves room for interpretation as far as her motives go.
** Though for the most part he's as LaughablyEvil as the average Disney villain, [[HistoricalVillainUpgrade Prince John]] from ''Disney/RobinHood'' crosses it when he plots to use Friar Tuck as bait to capture Robin Hood, knowing Robin Hood will save any friend of his who's in danger. [[EvenEvilHasStandards Even Sir Hiss is shocked to hear that his boss plans to hang Friar Tuck.]] He further goes over when he [[spoiler:tries to murder Maid Marian in the alternate, extended ending, which makes it all the more understandable when King Richard has his brother locked up and notes that were it not for their mother, he'd have him executed then and there]].
** In ''Disney/TheRescuers'', it's hard to tell when Medusa, who kidnaps a young girl named Penny to make her look in a flooded well for diamonds, crosses this, but it's evidently when [[spoiler:she refuses to let Penny up even when Penny's life is in danger. Oh, and did we mention that Medusa makes several direct attempts on Penny's life with a shotgun when she tries to escape?]]
*** Likewise in its sequel, it's not that clear when [[EvilPoacher McLeach]], who kidnaps a young boy named Cody to try to get the location of some eagle out of him, crosses this, but it's likely towards the end when [[spoiler:he ties Cody to a crane, lowers him into a crocodile-infested river, raises him back out again, and would dunk the boy in again until the power on his halftrack goes out. When this happens, he takes out a gun to shoot the rope, suggesting that he was originally intent on murdering Cody anyway and [[ForTheEvulz just wanted to torture the kid first]].]]
** Gaston from ''Disney/BeautyAndTheBeast'' comes close to this when he tries to blackmail Belle into marrying him by [[spoiler:threatening to have her father tossed in the loony bin]]. He comes closer to it still when, out of envy of the Beast, he [[VillainousBreakdown breaks down]] and stirs the town into an angry mob to make them kill him. However, Gaston finally crosses this by [[spoiler:stabbing Beast '''after''' Beast spared his life (and wearing a very ''[[SlasherSmile nasty]]'' [[SlasherSmile smile]] while doing it. [[DisneyVillainDeath He falls to his death soon afterwards]].]]
** In ''Disney/TheLionKing'', Scar (picked up) evidently crossed this by [[spoiler:murdering his brother Mufasa]]. It even seems, from Scar's facial expression at the edge of the cliff, that he realized there would be no going back once he did this, yet he did it anyway. Further evil actions (such as tricking Simba into blaming himself, or sending the hyenas after him) were done to get away with [[spoiler:murdering Mufasa]], which makes that the most likely candidate for MoralEventHorizon. When Simba finally tries to use the same words against Scar that ''he'' used against Simba ([[IronicEcho to "run away and never return"]]), instead of complying, proceeds to engage in an epic battle with Simba.
*** And in [[Disney/TheLionKingIISimbasPride the sequel]], Zira threatened to kill her own daughter for refusing to participate in an attack on the pridelands. [[EvenEvilHasStandards Zira's own followers defected to Simba after this.]]
** Governor Ratcliffe from ''{{Pocahontas}}'' crossed this when he tried to shoot the Chief ''after'' his fellow colonials chose to make peace with the natives, resulting in John Smith taking the bullet and almost dying. The settlers arrest him and have him shipped back to England in disgrace. All the while, [[NeverMyFault he tries to blame everyone and everything but himself for what had happened.]]
** Most Disney villains are [[LaughablyEvil goofy, somewhat quirky people]]. Not Judge Claude Frollo from their version of ''Disney/TheHunchbackOfNotreDame''. If he didn't cross this after almost dropping ''a baby'' down a well, he did after burning down multiple homes with families still inside them. And he kills Quasimodo's mother within the first few minutes of the movie! That means that he crossed the line shortly after the film began and just kept running. The fact that Frollo uses [[HidingBehindReligion religion to justify his actions]] only makes it worse.
*** In the opening sequence, the music seems to indicate a crossing of the M.E.H. when he decides to kill baby Quasimodo. About five seconds after he says, "A baby?... A monster!" The music jumps keys and tempo as he moves towards the well, and is supposed to make you realize "Oh S*** he's going to kill a baby in the first five minutes of a ''Disney'' movie!", so there will be NO redemption for this guy.
** Clayton from ''Disney/{{Tarzan}}'' crosses this when he shoots Kerchak, Tarzan's adoptive father, then, much like Gaston, tries to kill Tarzan after Tarzan spares him, resulting in a gruesome KarmicDeath afterward.
** In ''Disney/AtlantisTheLostEmpire'', Commander Rourke, who planned to steal the crystal from Atlantis all along without telling Milo, punched the King of Atlantis, mortally wounding him given how old he is. It was enough for [[TheMcCoy Dr. Sweet]] to turn against Rourke and try unsuccessfully to treat the King's wounds when everyone else was abandoning Milo and the people of Atlantis taking the crystallized Kida with them, even before Milo's sarcastic, fatalistic appraisal of the people he thought were his friends actually convinced Audrey, Vinny, Moliere, Cookie and Ms. Packard to join him and abandon Rourke, who had just crossed the line even further by punching Milo down for his "soapbox," and stepping on the picture of Milo and his grandfather, breaking the glass of the frame.
** Dr. Facilier of ''Disney/ThePrincessAndTheFrog'' has an entire plan that puts him over the line - in exchange for wealth and status, he's willing to sacrifice ''the souls of everyone in New Orleans'' to his "friends on the other side."
** Mother Gothel in ''Disney/{{Tangled}}'' officially crosses the line when she stabs Flynn Rider and very nearly kills him, so that Rapunzel's secret would die with him.
** In ''Film/WreckItRalph'', the BigBad [[spoiler:King Candy crosses the line late in the film, where after all his plans to stop Vanellope racing have failed, he resorts to [[WouldHurtAChild trying to beat her to death with a car-part simply to stop her from crossing the finish line and resetting the game.]]]]
*** Some people say that he crossed it by [[spoiler: putting ''Turbo Time'' and ''Road Runners'' out of commission, making homeless dozens of characters,]] because he couldn't stand not being the center of attention anymore. Not to mention, it's not a secret that he would have no issue with putting almost all of Grand Central Station out of commission as long as his massive ego is satisfied.
** In ''Disney/{{Frozen}}'', [[spoiler:If the true BigBad [[ManipulativeBastard Hans]] using Anna and [[ILied lying to her]] the entire time isn't bad enough, then there's him leaving her to die followed by his attempted murder of Elsa. Though WordOfGod states that having 12 older brothers, he was given no love growing up. Turning him into the monster he was]]
* [[TheGreatMouseDetective Rattigan's]] exposition song mentions he drowned widows and orphans ForTheEvulz. But halfway through the song, when one of his mooks (Who was drunk) calls him a [[BerserkButton rat]] (Which he very much looks like one, but WordOfGod states he's just a very large ugly mouse) causes Rattigan to have the mook [[DisproportionateRetribution eaten alive by his trained cat]].
* Speaking of Disney, {{Pixar}} movies often apply this as well. Again, here are some examples, in chronological order of movie release date...
** In ''WesternAnimation/ABugsLife'', Hopper [[KickTheDog punts thousands, if not millions, of puppies]] when he steals all the ants' food, but where he really crosses the MEH is when it's revealed by one of his goons [[spoiler: that he ''planned to squish the Queen'' after they finished the mass food theft ''just to teach the ants a lesson''.]] And then, when Flik [[ShutUpHannibal calls him out for his actions]], Hopper [[VillainousBreakdown breaks down and flat-out considers the ants enemies.]]
*** And both stealing the food and [[spoiler:plotting to squish the Queen]] were intended as a YouHaveFailedMe because a freak accident ruined the food originally set out for Hopper. Even worse, he originally decided against going through with it considering they had enough food to last them through the winter already, but then he remembered that Flik had stood up to him once before, and decides to take the opportunity to crush a potential rebellion.
** Randall Boggs from ''WesternAnimation/MonstersInc'' plans to kidnap small children so he can use the Scream Extractor on them, a device that sucks the scream and oxygen out of them, running the very real risk of [[WouldHurtAChild suffocating them to death]]. And unlike [[spoiler:Waternoose, who crosses the Horizon himself due to this same set of circumstances]], he can't claim to be a WellIntentionedExtremist, because his reason for doing it is petty jealousy against [[TheHero Sulley]] - jealousy which, as it turns out, goes back to the prequel, where it's revealed that [[spoiler:all this time, Randall had been beaten out as Scare Leader by a college dropout]], making his jealousy all the HarsherInHindsight.
** ''WesternAnimation/TheIncredibles'''s BigBad Syndrome is given a sympathetic history as [[spoiler: Mr. Incredible's former number one fan, cruelly (in his eyes) rejected by his hero]]. However, he shows his true colors first by [[spoiler:luring dozens of superheroes to their deaths under the guise of offering them employment]] and then later firing missiles at a plane that [[WouldHurtAChild he was well aware had children on board]].
** AUTO from ''WesternAnimation/WallE'' may very well be a WellIntentionedExtremist, but [[spoiler:giving [[TheWoobie WALL•E]] painful-looking electric shocks and then [[KickTheDog throwing him and EVE down the garbage disposal tube]]]] really helps to cement audience disdain for him.
** [[spoiler: Charles Muntz]] of ''WesternAnimation/{{Up}}'' ties a child to a chair and drops him out of a blimp. Said child gets rescued, but still...
** In ''WesternAnimation/ToyStory3'', Lotso establishes himself as a [[KickTheDog dog-kicking]] machine as he breaks, brainwashes, and tries to have Woody and his friends thrown away during the movie, but irrevocably crosses the horizon when he [[spoiler:betrays Woody and co. to die in the garbage dump's incinerator even though they saved his life a minute earlier]]. So much for [[RousseauWasRight Rousseau being right this time]], as is usually the case for Pixar. At least he gets a quite satisfying punishment: [[spoiler:[[AndIMustScream being tied to a garbage truck's grill for the rest of his life]].]]
