- Ballerina: Régine Le Haut pressured her daughter Camille to be successful at ballet and even tried bending over backwards to keep Félicie from succeeding at the audition, but those are small potatoes compared to later in the film, when she knocks out Victor and even one-ups this attack by trying to send Félicie falling to her death for winning the part.
- Steele from 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 condemning 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.
- Beauty and the Beast (Golden 1999) has a completely unintended case for the Beast: he refused to help a group of starving townsfolk and let them walk away empty-handed. This led to a majority of them, including the three comic-relief ghosts, dying because of his cold and selfish nature.
- Archibald Snatcher in The Boxtrolls doesn't seem that nasty of a villain and rather a goofy one at best, until later on in a flashback that reveals he kept Eggs' biological father captive for many years, driving him to insanity even though the flashback had him intending to murder him with a wrench. Even worse, he knows the whole time that the Boxtrolls are harmless but lied to the whole town simply so 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 He forced Eggs to watch his adopted family get murdered (they escaped in time, but still), and dressed Eggs up as the last Boxtroll and tried to kill him in a furnace. Archibald then rampages through the square and endangers everyone before abducting Winnie.
- Darla Dimple's servant, Max, from Cats Don't Dance crosses it in the climax when he outright attempts to murder Danny so he can't live to carry out his Batman Gambit. Up until that point, any evildoing he had performed was at the bequest of Darla, but when he hears Danny and Pudge setting up for the performance they were going to do when Darla's film was over, he resolves to stop them on his own free will, which nearly results in Danny getting killed.
- Melisha Tweedy of Chicken Run crosses it for plotting to turn all the chickens into Marie Calendar-style-pies if she didn't for executing Edwina, just because she was too weak to lay eggs
- Chester V from Cloudy with a Chance of Meatballs 2 crosses this by kicking Flint down a cliff to try and kill him, revealing his Evil Plan to have all the sentient food animals turned into food bars, and trying to drop Flint's friends into a machine to shred them to bits.
- Lord Barkis Bittern in Corpse Bride crossed the line a long time ago after he murdered Emily in cold blood to steal her dowry.
- In The Curse of the Were-Rabbit, 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 that Wallace is really the Were Rabbit, and is now more determined to kill him so he can have Lady Tottington.
- Grandma Got Run Over by a Reindeer. Slimy, and sexy Ensemble Dark Horse Cousin Mel is so desperate to be rich she tampers with Grandma's fruitcake intending to poison or possibly even kill innocent strangers to stop customers from coming to their store. When that plan unexpectedly gets thwarted, she refuses to reveal that Santa Claus really did run over Grandma to make sure she stays missing, exploits Grandpa's senility to get power of attorney on the store, and later kidnaps a now amnesiac Grandma in order to frame Santa and get all his money.
- Heavy Metal. 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? By pointing a gun at him and demanding the entire amount for herself. The two 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 How to Train Your Dragon 2, if it wasn't clear enough by then that Drago Bludvist is 100% morally bankrupt, it most certainly was when he uses his Alpha to brainwash Toothless into turning on Hiccup, resulting in Stoick the Vast's Heroic Sacrifice.
- In The Iron Giant, Kent Mansley crosses it when he drugs Hogarth and takes him to the barn then threatens to have him taken away from his mother if he doesn't reveal where the Giant is. He then crosses it even further by having the Giant shot down, fully aware that Hogarth is with him, and after lying to Annie and Dean that they'll be safe. This results in Hogarth seemingly dying and the Giant going on a Roaring Rampage of Revenge, which could have potentially ended with the death of the human race had Hogarth not calmed him down.
- Kung Fu Panda:
- When Tai Lung 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.
- Lord Shen starts the second movie far on the other side of this trope. When he overhears a prophecy that "a warrior of black and white" will stop his plans to conquer China, he resorts to the genocide of an entire panda village in an attempt to avert the prophecy.
- Legend of the Guardians: The Owls of Ga'Hoole: Kludd moonblinks his baby sister, which is essentially zombifying her. In the book, he crosses much, much sooner, although Soren/the reader doesn't know it at first. He 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.
- In The Missing Lynx, Newmann overly crosses the line when he chose to try again hunting on the fugitive animals repeatedly, usurps Noah's control, and threatens to kill Felix in order to use Lynxette as bait.
- The Nut Job:
- Raccoon crosses the MEH when he leads Surly to destroy the Tree, and banished him hypocritically. He reveals his true colours to the rest of Surly's gang of rodents via trying to suppress the nut heist. Thank God The Caligula got his just desserts upon getting himself surrounded by the sharks while trying to concoct an alternative plan.
- Mayor Percival J. Muldoon of The Nut Job 2: Nutty by Nature crossed it when he replaced Liberty Park with Libertyland, if he didn't cross it for plotting revenge on Surly. He passes blame on Surly and his gang by getting away in a hot air balloon, yet Surly defeats him and the Mayor gets his just desserts for his crimes.
- The Judge and the Puritans crossed it far in the past, when they hanged Agatha — an eleven-year-old — all because she could see ghosts. Even after he decides to help them when he sees their genuine remorse, Norman still refers to what they did as "something unforgivable."
- The modern day townspeople cross this same line when they actually try to lynch Norman. Yes, they stopped when Norman's friends call them out and talk sense into them, but the mere fact that they seriously considered and attempted it is on its own irredeemable and is on top of abusing Norman for a long time.
- In The Powerpuff Girls, Mojo Jojo is an incompetent and harmless villain. In The Movie, however, he's anything but. 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 Break Them by Talking:Mojo: Can't you see? None of them will ever understand you the way I can. For we are kindred spirits whose powers spring from the same source. 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! And we shall rule! All we have to do is work together. Girls, join me.
Blossom: 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: 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 had down to go, becoming more redeemable rather than less.
- Pharaoh Seti in The Prince of Egypt 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.
- The Road to El Dorado:
- Tzekel-kan shows that he is willing to act as accessory to the massacre of his own people with his attempted sacrifices and pressing requests towards the gods to let him purge the city of those that he considers sinners. Even arguing that presiding over a religious system that, while certainly unpleasant to both Miguel and Tulio's European perspective and the audience's modern-day one, would've seemed perfectly natural to a man of his time and culture, one cannot ignore that he was the only one obsessed with enacting it even when the gods denied his request, or the fact that he sacrificed his own henchman, who if anything else, should not be considered disposable, according to his beliefs. And toward the end of the film when he agrees to lead the Conquistadors to the city and allow them to pillage it, not only to spite the Chief for banishing him, but also because he sees them as the ideal gods, it becomes clear that he's genuinely evil no matter whose perspective you're coming from.
- Cortez would have his expedition which would bring slavery and destruction to the so called heathens as his MEH if he didn't cross it when he planned to have Miguel and Tulio flogged and then sell them into slavery, all for accidentally stowing away on his ship.
- The Grand Duke Of Owls crosses this in Rock-A-Doodle when he nearly strangles Edmund to death.
- Rugrats in Paris:
- Coco LaBouche, acted like your typical Child Hater who only pretended to love Chas just so she can go up in the social ladder. Her acts started when she wrenched Chuckie's Tragic Keepsake out of his hands and then ordered Kira to destroy it. Even Angelica looked shocked!
- Then, it only went downhill when she and Jean-Claude cross this when they're willing to lock children away in a warehouse for the sake of a perfect wedding.
- Jean-Claude pilots the Super Escargot mecha against the babies' Reptar mecha and attempts to destroy it, knowing full-well the babies are inside and even gleefully going along with it.
- Sausage Party: Douche crosses it when he kills an injured juice box by draining him from his crotch.
- Sheep & Wolves: Ragear, who starts off as the usual contrast to The Hero, goes past the point of no return when he kills Magra just to claim the position of the wolf village leader.
- The first movie has Lord Farquaad already commit several heinous acts as the film progresses, such as banishing several enchanted creatures to Shrek's swamp as if it was an unimportant piece of land and taunting Gingy with his severed legs, and having Mama Bear made into a rug off-screen all because he believes that fairy tale creatures are tarnishing his "perfect world". However, he truly crosses it when, after Fiona reveals her ogre form, he orders his guards to take her and Shrek away, the latter being sentenced to a Fate Worse than Death and the former about to be trapped in her tower for the rest of her life. At that point, nobody felt sympathy for him when he got eaten by a dragon.
- In Shrek 2. The Fairy Godmother and Prince Charming cross this when she gives Harold a love potion to ensure Fiona falls in love with her son Charming. Charming for willing to go along with that and steal Fiona away from her real love just so he can become king of Far Far Away. Harold comes close to this (he did try to have Shrek killed so Fiona and Charming could be together and he could fulfill his promise to Fairy Godmother) and nearly gives Fiona the love potion (albeit reluctantly) but stops at the last minute when he sees Fiona still loves Shrek and he does not wish to violate her free will.
- Shrek the Third has Charming cross it yet again when he appears to have killed Shrek. Keep in mind, this is after Artie's "You Are Better Than You Think You Are" speech and getting all the villains to pull a HeelFace Turn.
- Shrek Forever After's main plot involves Rumpelstiltskin tricking Shrek into giving up the day he was born so he could take over Far Far Away. In the timeline where Shrek didn't exist, he turned it into a dictatorship where literally everyone's lives are far worse, and we even get to see him executing a witch for allowing Shrek to get away.
- Eris of Sinbad: Legend of the Seven Seas crossed this when she unsatiably took matters into her own hands upon framing the titular protagonist by stealing the Book of Peace. She pushed even further when sending her pet Ice Eagle, Roc to attack Sinbad and his Crew
- Superman in Superman vs. the Elite 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. 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 Elite themselves jumped through the horison when they decided to kill Superman simply because he doesn't agree with their methods.
- Thumbelina: Mona is arguably one of the most evil characters of Golden Films, since she outright disregards the lives of the little people and is not above selling Thumbelina to Mr. Mole with a fake promise of helping her on her mission. Mr. Mole also crosses the horizon with his willingness to go with such a plan.
- The 2003 Shredder crossed it in Turtles Forever when he tries to kill the Turtles Prime while ignoring Karai's warnings that killing them will wipe everyone out of existence, 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).
- More than half of the short animated film Zero in one long crossing of the horizon for everyone at the expense of the title character who happened to be born with number zero on his chest. He is continuously abused and physically assaulted and they almost murder his pregnant wife in front of him after imprisoning him. It is clearly shown that this happens to all zeroes and it is a film about the horrors of racism, casteism and social unequality.
