Moral Event Horizon / Western Animation

"No one in their right minds would ever confuse Peter and Lois Griffin for good parents. But in [Go, Stewie, Go!], they are borderline criminal.
—The Parents Television Council

Shows with their own pages


  • Adventure Time
    • The original Earl of Lemongrab definitely crossed it in "Too Old". Even though Lemongrab still left his clone alive and kept him alive on a machine, he constantly abuses him physically and verbally. Not only that, he attaches shock collars to all of their 'sons' and forces them to entertain him after he becomes a Fat Bastard. Then it gets even worse when, after Lemongrab 2 thinks his twin has finally come to his senses after hearing Lemonhope's song, Lemongrab mercilessly eats his twin (again) and orders their boys to kill Princess Bubblegum, Finn (who's too distracted by his relationship blues to care), and Lemonhope.
    • The Lich crosses it either when he kills Billy or when he kills Prismo, both of which were done during attempts to end all life in the universe. The latter kill is especially egregious as his victim was confused and helpless, and it's clear the Lich had no reason to kill him other than For the Evulz.
  • American Dad!:
    • Roger the alien among us has always been somewhat amoral and sociopathic, but the behavior has been flanderized to an unsettling degree in later seasons. He may have finally crossed the line in the season 8 premiere. He becomes obsessed with Hayley, an obsession which culminates first in his shooting and injuring her then kidnapping her. He takes her to an abandoned warehouse, ties her arms & legs to the posts of an old bed and tells her he PLANS TO SKIN HER ALIVE AND WEAR THE SKIN in order to "be closer" to her. After menacing the struggling Hayley by laying out the various tools he plans to use in front of her, Roger is interrupted by Hayley's husband, Jeff Fisher who finally gets him to listen to reason. Just when it looks like everything is going to be okay, Roger takes Jeff into the bathroom, SKINS HIM ALIVE AND COMES OUT WEARING HIS SKIN thinking it will make Hayley love him as much as she loves Jeff. The episode ends with Roger realizing he's no longer obsessed with the now-horrified Hayley and shows Jeff is still alive and will be getting his skin back, but it's still going to be difficult to erase such a terrifying episode. How would Jeff & Hayley be able to live under the same roof with him ever again?
      • Roger crossed the line again in "Virtual In-Stanity", where he kills five teenagers and brutally hits each with a limousine that he stole, simply because they didn't pay for their trip.
    • Barry, when he is not medicated, crosses this in "With Friends Like Steve's", which takes advantage of the family of Steve and earns the trust of Stan, then he blames Steve for making atrocities for them to go away to a correctional, then tries to kill Stan.
    • Stevearino, Steve's Evil Knock Off is probably the most evil character in the series, to the point where the show doesn't even try to portray his actions as Crossing the Line Twice. His atrocities are not justified and are played very seriously, and include, but are not limited to, the following: Murdered and tortured multiple cats, tried to take over the original Steve's life by kidnapping and stuffing him in a small cage, planning to kill him later, and nearly killed both Stan and Francine when they finally figured out what was going on.
    • One-time characters Nick and Cassandra, Francine's biological parents, either do this by abandoning her as a baby because babies can't ride first class, or when they wouldn't save Stan from being trapped under a wooden beam in his burning house because they didn't want to become a liability.
    • Emperor Zing, another one time character has crossed this in the only episode he appears in. He humiliated numerous alien slaves in public by showing them memories of the rough patches they went through with their loved ones in public just for the sake of propaganda and deceiving the public while calling the whole ordeal a test and then removing the "tools for love" from such aliens who challenged his belief that love does not exist and he did that test on Jeff. He also forced the Majestic to only show the bad memories of the people who took the "test" and threatened to blow The Majestic into space if he disobeyed and showed the good memories. It is also implied that he tried to kill Roger by sending him to Earth to be a crash test dummy just because Roger cheated on Zing with another man, which could mean that Zing crossed the MEH long before his début.
    • Stan crosses it when he tries to "unclone" a couple of cloned teenage girls that Steve created by killing them so he would not lose his job. He kills one such girl who tried to run away from him, which shocked Francine with Stan telling her not to judge him since she was just a clone.
  • In American Dragon: Jake Long the Huntsman is presented as evil and devoured by his hate for magical creatures in general and dragons in particular, but he still has a somewhat soft spot for Huntsgirl/Rose. Then we learn he kidnapped her from her parents minutes after she was born. But that's not his MEH; after all he WAS a good Parental Substitute to Rose and gave her a solid set of morals, aside for that hate for dragons she later overcame. No, his MEH is when he finds out of Rose's Heel–Face Turn and reveals he knows where her parents are and threatens to kill them if she doesn't lead him to the Aztec Skulls in the hands of the dragons and fights for him while he activates them. Thankfully, this directly leads to the destruction of the whole Huntsclan at Rose's hands.
  • Walter Wolf, Slappy Squirrel's nemesis in Animaniacs, sinks to the ultimate low in "Rest In Pieces" by faking his own death in order to turn everyone against her, including her nephew!
  • As of the second episode of the second season, Archer has implanted a faulty Russian mind control chip into the head of Len Trexler, head of ODIN and possibly his father. Even Archer himself feels bad about it, if it has any permanent damaging side effects.
    • Barry's Moral Event Horizon was probably murdering Jakov, another candidate for Archer's father.
    • Major Jakov's Moral Event Horizon probably came in "Dial M For Mother", when he brainwashes Archer to turn him against Malory.
    • Malory crosses the Moral Event Horizon in Season 2 and 3 flashbacks to Sterling's childhood: she got him drunk and taught him to gamble so she could steal his Halloween candy, and berates him for being unable to hold his liquor. She bought him a bike for his birthday, then stole it and punished him for losing it, without even telling him what she'd done.
  • In the Redhill story from Animated Tales of the World , the Adviser crosses this when he orders the guards to kill Nadine and his grandmother, even though he had already successfully convinced the Rajah that he shouldn't take advice from a young boy such as Nadine.
  • Avatar: The Last Airbender:
    • In the season 1 finale: Admiral Zhao crosses this when he kills the moon spirit. It hadn't even done anything to him: he wanted to make a name for himself so that he would be remembered by history forever, but as Iroh told him, "History isn't always kind to its subjects."
    • Fire Lord Ozai started at this and just kept running, becoming the most thoroughly unsympathetic villain in the entire series. After his son disrespected one of his generals in the war room, he burned his face and sent him on a Snipe Hunt. When Zuko mouthed off to him years later, he tried to kill him with lightning. Still, villains have been redeemed from worse. What truly defines him is his utter excitement at carrying out his plan in the finale, which is to quell rebellion in the Earth Kingdom by burning the continent to nothing.
    • For Azula, many people felt she crossed it after she killed Aang when he was going into his Avatar state at the end of Season 2. He gets better. But if that wasn't enough, she really crossed it when after she embraces her insanity, she used Katara as bait so she can kill Zuko with a lighting strike. It almost works.
    • Sozin stabbed his best friend Roku in the back (though at least he seems to slightly regret it in the end) and ordered the annihilation of the Air Nomads.
    • Azulon didn't like Ozai mocking the death of Iroh's son, so he orders Ozai to kill Zuko to teach him a lesson on what it's like to lose a son. Zuko could have easily become just like that if it weren't for the guidance of Iroh.
    • Long Feng, the Earth Kingdom's Evil Chancellor, who brainwashes Jet and then kills him when he resists.
    • Hama has every reason to be sympathetic: she was stolen from her tribe, kept locked up in a prison that took every precaution to prevent her from bending, and kept there for decades. In fact, she uses this information to garner Katara's sympathy, then reveals that she escaped by bending the blood in the bodies of the guards, and is now using this same power to herd innocent civilians to a mountain where she keeps them prisoner out of blind revenge. And then she tries to forcibly teach Katara the technique, and sends her into an Heroic B.S.O.D. by using her bloodbending power to manipulate Aang and Sokka into fighting a panicking Katara. She serves as a reminder that even the most innocent people in a war can become no better than those who persecute them if pushed far enough.
  • In Sequel Series The Legend of Korra:
    • In the episode "When Extremes Meet", Councilman Tarrlok crosses it when ennacts a curfew on a Non-Bender district of Republic City, shuts off the power to said district so he can arrest those who "break curfew" as they come out to complain, arrests the new Team Avatar for trying to help them, and to top all off, bloodbends Korra and has her exiled from Republic City and left to die alone, locked in a box.
    • Amon and the Equalists finally cross this by Jumping Off the Slippery Slope and launching a full-scale invasion of Republic City, complete with bombings and gas attacks.
    • In the Origins Episode Beginnings, we are introduced to Vaatu, spirit of chaos and all around God of Evil. His moment is when he corrupts Wan's spirit friends into dark spirits and causes a fight between them and Wan's human friends. Wan tries to stop the two forces, but he isn't a full Avatar yet and the strain knocks him out. When he comes to, he finds the valley in flames and Vaatu gloating about how all of Wan's human friends were completely slaughtered.
    • Unalaq not only crosses it in New Spiritual Age, he polevaults across it by nearly wiping out Korra and Jinora's souls. Note, Korra is his niece and Jinora is an 11 year old girl. Erasing any ambiguity of his crossing is his sadistic smile which he does these things.
    • Zaheer and his Red Lotus gang pretty much cross this when after Kya and Bumi are beaten from their battles with Ming Hua and Ghazan, they start attacking Tenzin savagely. If that wasn't enough, then Zaheer definitely crosses it in the season finale by poisoning Korra so that she can be forced into the Avatar State and his cohorts can kill her, thus permanently ending the Avatar. And his reaction to Korra apparently dying in her grieving father's arms is to laugh in triumph.
    • While Kuvira lost more and more of her apparent redeeming qualities over time, she seems to finally cross the line in Kuvira's Gambit. In the episode, Korra manages to capture Kuvira's fiancé, Baatar Jr., as Kuvira is trying to take over Republic City with her new super weapon. Baatar contacts her and tells her that Korra is threatening to take him away from her forever unless they stand down and leave. He says that he loves her, and even without Republic City they can still get married and rule the rest of the Earth Empire together. As he's speaking with her, Kuvira traces the radio signal to where he's being held by Korra. Once she has the location, Kuvira tells Baatar she'll back down and she loves him. Then she fires her super weapon on the warehouse where he's being held, willing to sacrifice him just for the chance to kill Korra. At the very least, her tone of voice and body language indicate that she feels some regret over what she's doing, but her act still proves that her empire and her ideology come before everything else.
  • Red Skull from The Avengers: Earth's Mightiest Heroes! crosses this in season 2 where we find out that he captured and brainwashed Bucky and turned him into Winter Soldier, an emotionless killing machine and made him commit several atrocities, and did same to Doc Samson and The Falcon. Skull also infected the entire New York city with his Dust of Death, which might have possible killed many innocent civilians, just to discredit Avengers and kill Captain America, while being under guise of "Dell Rusk", the secretary of US defense.
  • The Batman: Joker's torture of thugs is certainly crossing this, plus what he did to Ethan. And Tony Zucco crosses it in the first ten minutes of his appearance by killing Dick Grayson's parents (before he became Robin) just because Mr. Grayson called the cops when Zucco got a bit threatening.
  • Batman: The Animated Series:
    • The Joker's serial murder spree (complete with victim photos) using laughing gas in one of the earlier episodes.
    • Roland Daggett crosses this when he tries to blow up Crime Alley, knowing fully well that there are people that live there. It was also shown some of the residents are children. Daggett's actions would have resulted in several people dying and he would have no problem or remorse to indirectly murder them for his own gain.
    • Warren Lawford aka Fox from the Terrible Trio crosses the line when he tries to kill his own girlfriend after she knows too much. Even his friends were shocked at his actions.
    • Ferris Boyle starts crossing this line when he interrupts Victor Fries's cryogenic experiment that can save Nora's life, even though Victor warns it could kill her. But when does he permanently cross it? By kicking Victor into a collection of chemicals that started his transformation into Mr. Freeze and leaving him and his wife to die. Even Batman is horrified at what the newly named Humanitarian of the Year did and leaves him encased in the iceberg instead of breaking him out with the coldly delivered line "Good night...Humanitarian."
  • Batman Beyond: Return of the Joker gives the Clown Prince of Crime a rather infamous line-crossing moment: he kidnapped Robin, tortured and mind raped him for three weeks, mutilated him, "fixed" him up as Joker Jr., and invited Batman over to see his work in detail (which included home video of the boy's torture labeled as "Our Family Memories"). He then reveals that he's learned Batman's secret identity, mocks him for it (and for not having the balls to kill him after all this), and knifes him before he tosses "J.J." a spear gun to finish him off with. Also worth mentioning that this particular MEH crossing was the former page picture.
  • Vilgax in Ben 10, after getting a valuable crystal, murders the entire planet for no reason. They weren't doing any harm to him, he fired on the planet for no reason other than to test just how powerful the crystal is, and shows no regrets.
    • Ghostfreak wanted to plunge Earth into darkness, the result of which is shown to be horrifying mutations of all living things. That was just a side effect of his plan that he didn't even care about.
    • Kevin 11,000, an alternate future version of Kevin all grown up, crosses the line when he decides the best way to take revenge on Ben is to kill Ben's 10-year old son. And when Kevin's own son tries to stop him, he literally throws him aside and shows that he doesn't care about him at all, and then seems perfectly fine trying to kill him too when he fights back.
    • Zombozo gets his by kidnapping a 10 year old girl and draining her of her energy until she's nothing but a shrivaled husk of her former self, speaking of it so lightly that it's implied it's not the first time.
    • In Ultimate Alien, Aggregor did this onscreen by murdering five innocent aliens in cold blood. However, he could be considered to have already crossed it when he came up with a plan ending with him murdering a newborn.
    • Defying Villain Decay, Zombozo crosses this by forcing Ben's mother to walk a tight rope and then lighting it on fire underneath her, intent on either burning her alive or sending her falling to her death. This pushes Gwen so far that she assumes her One-Winged Angel form and scares the living crap out of him.
    • Colonel Rozum imprisoning 775 aliens in a horrible underground prison for over five decades, many of whom likely did nothing wrong. Prisoner 775 for example was exiled to Earth by an alien tyrant who he was trying to save his planet from. He told Rozum this, multiple times and they didn't listen. The only good thing about this guy is his love for his family.
    • Prisoner 775 himself has one. Once he escapes, he intends to exact his revenge against Rozum. A viewer might not condone it, but could certainly understand his reasoning for revenge against just Rozum. Problem is, 775's targets expand to Rozum's whole family. They had absolutely nothing to do with his captivity, and he knows it. He just wants to kill them to make Rozum suffer. This may have been an intentional crossing of this on his part, as in the end he attempts Suicide by Cop, so he may have just wanted to do something that would force Ben to kill him and end his suffering along with getting his vengeance.
    • Charmcaster sacrificing thousands of souls, even killing Ben, Gwen, and Kevin, in order to make a Deal with the Devil that will resurrect her dead father. Though to be fair, she does have a My God, What Have I Done? and go into a Villainous B.S.O.D. when he calls her out on it, and since this is a series where alien Nazis like the Highbreed can be forgiven...
      • Word of God comments made online actually seem to indicate that this act is, in fact, an INVERSION of the Moral Event Horizon. Instead of being the point where Charmcaster crosses the line into irredeemability, her realization of how wrong it was due to her father's words has pushed her completely AWAY from evil, and she is thus now a True Neutral character rather than still a villain.
    • Captain Nemesis crosses the line in "To Catch a Falling Star" by becoming the first successful hands-on murderer in the series. He kills several people, including a random motorist just to steal his car. Even his Pet the Dog moment at the very end doesn't bring him back across the line.
    • In Omniverse, Malware crosses the Event Horizon when he destroys his own homeworld, Galvan B, in the finale.
    • Years after he crossed it in the original series, Vilgax undergoes Character Rerailment in Omniverse in And Then There Were None, where he unleashes a bomb that erases all timelines save for the one he's in now, where its version of Ben Tennyson doesn't have an Omnitrix. Essentially, he's wiped out entire worlds, killed a number of lives too great to count, including his own allies, along with the main timeline's Ben Tennyson, all to exist in a world where he can kill a Ben Tennyson who can't fight back and erase him from existence.
  • While most of the antagonists in The Boondocks are just irresponsible, greedy, or selfish Jerkasses, there are moments where some had crossed the line
    • Lamilton Taeshawn is not exactly a child you want to babysit, but he crosses the line when he outright threatens to shoot Riley simply because he doesn't want to hang out with him.
      • Others thought he crossed it when he killed a dog that was chained up and couldn't reach him.
    • Ed Wuncler Sr. pretty much kicks dogs left and right, but his most heinous crimes include:
      • Tricking Jasmine into slave labor in her own lemonade stand with false promises of a pony so that when people start protesting, he can make a killing off "cruelty-free lemonade" and stick Jasmine with a $300 bill, as all the money she made was not enough to cover the expenses of professionalizing the stand at Wuncler's request. Wuncler even goes so far as to blame Jasmine for the failure of the stand!
      • Giving Granddad his own soul food restaurant, knowing the food is so unhealthy and addictive, the resulting crime rates would devalue neighboring Meadowlark Park enough for him to purchase and develop it cheap.
      • Having his grandson and his best friend set bombs in a building just to kill ONE man so that can play him up as a national hero and sell loads of merchandise. Most damning of all is that all his evil acts are for the sole purpose of money, despite being rich enough to have connections to the president.
    • Wuncler's son is as bad as his father; when Robert was in his debt, he has Robert sell himself and his family into slavery and has them live and work in a realistic slave themed theme park, along with the others in his debt.
      • Uncle Ruckus crosses the point of no return by taking part in running said realistic slave themed theme park, whipping Robert (the closest thing to a friend he has ever had) and taking sadistic delight in their torment. He shows extreme glee when Huey is about to have his foot chopped off.
  • Captain Planet and the Planeteers:
    • Verminous Skumm crosses the line in almost every episode he appears, but the most infamous moments are in episodes "Mind Pollution" and "A Formula For Hate": in the former he hands out mind-affecting drugs to teenagers, causing them to go insane and is responsible for the death of Linka's cousin, who died because of fatal overdose, just for the joy of ruining their lives and those of their friends and families, and in the latter he harassed an HIV positive teenager and spread lies about AIDS because the kid was an easy target and used the naivety of the townspeople about AIDS to spread hatred and take over the world. Almost every episode featuring Skumm has him crossing the MEH, but these two episodes are his most infamous Moral Event Horizon moments.
    • Dr. Blight crosses the line in episode "A Good Bomb is Hard to Find", where she and her future self went back in time to World War II and decided to sell nuclear bombs to Hitler (sure he was Captain Ersatz and was only referred as "The Fuhrer", but it was obvious who he was supposed to be). The Planeteers even say that this is low, even for Blight.
    • Zarm is one nasty work himself for two words: scorched earth.
  • In The Cleveland Show, after Rallo almost drowns and blackmails Cleveland for it, Cleveland dunks Rallo's head in the pool twice just so Rallo would stop bossing him around.
    • Another candidate for this trope comes in "A Rodent Like This", Cleveland gets heavily attached to a rat and raises it as a pet. The rat winds up biting Donna and when it's confirmed the rat has rabies, Cleveland decides (at first) to not have the rat killed to test it for rabies, which basically meant he would rather let his wife die than to kill his beloved "pet". Luckily, Donna strong-arms Cleveland into agreeing with her and the doctor.
  • 'Codename: Kids Next Door'':
    • Father crossed the line when he planned to bake a bunch of innocent kids into a cake.
    • Grandfather was also the one who's responsible of making Father who he is. He somehow traumatized his own son into being scared of broccoli.
    • While most of the villains are willing to hurt or even outright kill children, Nurse Claiborne tries to kill Numbuhs Three and Five in cold blood!
    • Chester trying to feed kids to sharks. Specifically, sharks that can drive cars.
  • Though he isn't nearly as bad as the Devil in The Bible, The Red Guy crosses this in Part-Time Job, an episode in which Chicken was looking for employment and worked for him. The only catch was him being stripped of his feathers and almost being cooked alive in one of The Red Guy's schemes.
  • Courage the Cowardly Dog features Mad Dog. He abuses Bunny to the point where he buries her up to her neck in dirt when she tried to escape, he tried to drive her and Courage down with his car, and most importantly, he somehow caused Bunny's best friend Kitty to be convinced that all dogs were evil.
    • Just anything Katz did.
    • The mad scientist who sent Courage's parents to space.
    • Eustace maybe a Jerkass to begin with but he crossed it when he gathered up the villains to kill that "Stupid Dog".
  • Danny Phantom played it oddly straight with Danny's alternate future. The whole "Dark Danny creation" scene was horrific and it horrified even Vlad, which really says something. Also see Dark Danny's first appearance where he apparently kills multiple people on screen. Ax-Crazy, indeed.
  • While the villains of Darkwing Duck are often Laughably Evil, Negaduck crossed this in "Just Us Justice Ducks." When the heroes surrounded him, Negaduck threatens to throw the switch that kill everyone including himself. But even after the heroes back down, Negaduck decides to do it anyway out of pure spite.
  • The Beagle Boys in DuckTales were Obviously Evil from the start with their card carrying and cartoon-ish villainy. But they've finally crossed it in the Grand Finale when they've turned Huey, Dewey, and Louie into golden statues.
  • Near the end of the Ed, Edd 'n' Eddy series, Eddy's Brother crossed this within seconds of making his first appearance when he began to mercilessly beat the shit out of Eddy, and freely admit he's always done this to him.
  • The Fairly Oddparents movie "Wishology" has the Lead Eliminator trying to kill Timmy is bad enough. But when he became the Destructinator, he plans to destroy the world in a Earth-Shattering Kaboom.
    • Vicky crosses it in the TV film, "Channel Chasers", when she frames Timmy for destroying his family's portrait, burning down his family's grand piano, and writing spray paint on the living room wall just to see Timmy suffering a horrible punishment from his parents. And among other things, zapping Future!Timmy's belt, causing him to fade away back into the future.
    • The Pixies crossed this in "School's Out: The Musical" with the revealed they'd kidnapped a child and raised him for his entire life as their own personal Tykebomb to try and take over Fairy World and the Earth.
    • The Anti-Fairies crossed this (and if "School's Out" wasn't their's, this certainly is for the Pixies) by using Poof as a weapon to destroy Fairy World for revenge, then choosing to destroy the Earth For the Evulz.
    • The whole gambit Norm pulled in "Fairy Idol". He was already a Jerkass Genie, but the way he ruins Timmy's and Chester's lives is just terrible.
    • Remy Buxaplenty was originally a Villainy-Free Villain who was merely jealous of Timmy's Fairies and happiness, and while he might do an underhanded tactic here and there, like when he tricked Timmy by faking friendship so his life would be too perfect and his fairies would leave him, he never resorted to violence. He went from sympathetic Lonely Rich Kid to full-on Card-Carrying Villain as of "Operation F.U.N." where he, Juandisimo and Chief Shallow Grave put Timmy and his friends through Training from Hell, running them absolutely ragged and cutting Timmy off from his fairies by having them confiscated in goldfish form. The MOH crossing really comes in when he traps them under a butterfly net, which renders them powerless with a missile ready to obliterate them. He was willing to KILL Cosmo and Wanda!
  • Family Guy:
    Bertram: "Worth it!"
    • In the episode "Be Careful What You Fish For", Stewie shows Brian what horrible conditions the preschool is in (kids gambling, a dead body, and a pedophile abducting a child to name a few) and asks him to talk to Emily, the teacher, about it. When Brian sees her, he instantly is attracted to her and decides to date her instead. Brain then makes excuses on why the teacher isn't that bad while he ignores what Stewie has to endure in the preschool. Things get more questionable when Stewie comes home with his arm out of its socket because Emily pulled on it too hard while she was disciplining Stewie for back-talking to her. Brian then tries to shut Stewie up when he tries to tell Lois what is going on. In the end, Brian does call the cops on Emily, but only because she had a boyfriend already.
      Mr. Enter: I mean, if he was doing this to get laid, he'd still be a piece of shit, but at least there would be a fucking reason!
    • While Lois is on sorta-higher ground than Peter, some may argue that she FINALLY crossed the moral line in "Go, Stewie, Go!" She notices Meg's perfectly normal boyfriend (Meg is not well liked), imagines her having sex with him (even though it IS technically legal in Rhode Island because said boyfriend is 17, one year over the Age of Consent in RI, it is still creepy and dickish), gives him her "schedule", making out with him, and, when caught by Meg, she says "Uh... rape?" Yeah, Meg did not buy it.
    • Diane Simmons crossed it in "And Then There Were Fewer", when she kills several people, and then frames Tom Tucker, blaming him for her termination from Quahog 5 News.
    • Jeff (the abusive boyfriend of Quagmire's sister) from "Screams of Silence: The Story of Brenda Q." is the most evil villain that Family Guy ever had, simply because, unlike the others above, none of his Jerkass behavior is played for laughs or justified. The moment when the show finally declares that it is impossible for him to turn back is when he knocks out Peter and Joe and attempts to strangle Quagmire on a "camping trip" (the three were actually going to kill him, although they were MUCH more justified).
    • Meg was shown to be no better than any of them, when she almost crossed it in "Friends Without Benefits". After finding out that a crush of hers is gay and is attracted to her brother, Meg decides to arrange it so that Chris will have sex with him since it would be the closest thing to actually having sex with her crush. Her plan is to drug Chris and essentially have him date-raped. While Meg's life is hell, and she never goes through with her plan, the fact she considered it is bad enough.
  • In the Forest Friends episode "Bush School", Anthony's father Mark crosses this when he tries to start a forest fire.
  • In Foster's Home for Imaginary Friends: In her second and last appearance, Berry ties up a family and tries to KILL Mac.
  • Futurama:
    • Zapp Brannigan is a grade-A Jerkass, putting himself above others and commanding suicide missions. However, some may argue that he crossed the line in The Beast with a Billion Backs. Kif dies as a result of trying to go against the dimensional portal Yivo. After hiding in a shack with Amy and Leela, Zapp begins "reminiscing" about Kif, then sleeps with Amy. So, yeah, the jerk used a widow's husband's death.... to get laid.
      • If he didn't cross it then, Zapp definitely crossed it in "In-A-Gadda-Da-Leela". Leela and Zapp crash on an unknown planet, alone and without supplies. Leela is trapped under a fallen tree, and delirious from lack of water, and the Earth has apparently been destroyed. Through the episode, Zapp appears to be helping Leela get better. Then we find out that the planet they crashed on is Earth, and Zapp has not only been using their current predicament for an Adam and Eve Plot-style seduction, but placed the hazards there so that he'd have a better shot at sleeping with Leela (again). The writers themselves seem to know that what Zapp did was unforgivable: they originally planned for Zapp to get off scott-free, but changed it to Leela punishing him in a rather fitting manner.
      • His first appearance in the series, Love's Labors Lost in Space, had him describe his "heroic" victory against a rampaging army of Kill-bots: He knew each Kill-bot had a preset kill-limit, so he just sent wave after wave of his own soldiers to die at their hands until every one of the robots had reached its limit and shut down.
    • Bender crosses it in " A Pharaoh To Remember" when he makes the decision to become the next pharaoh of Osiris 4 after its previous pharaoh dies in an accident. He then proceeds to make all the slaves of Osiris 4 take on the grueling task of building him an oversized statue with a flamethrower in a mouth that constantly screams "remember me" as Bender desired to be a remembered figure. His actions in that episode even had him treat Fry and Leela like slaves.
    • Richard Nixon's Head crosses it in "Crimes Of The Hot" when he attempts to commit genocide on all the robots of Earth by tricking them into attending a party on the Galapagos Islands so he could exterminate them all there. His reason for doing this was to provide a quick solution to the global warming problem but his actions are considered to be an act of genocide and racism and it can be considered a hate crime. ***Ogden Wernstrom also crosses the MEH in the same episode for the exact same reasons
    • Most of the citizens of Earth cross it in " A Taste Of Freedom" when they decide to form a mob against Zoidberg and call for his death just because he ate a flag out of patriotism and euphoria for Earth, which forced Zoidberg to seek asylum in the decapodian embassy to avoid getting lynched. Nixon and even Earth's supreme Court joined in on this.
    • Yivo crosses it when in "The Beast With a Billion Backs", shklee decide to mate with everyone in universe gamma and make all of them "love the tentacle", which is to say that Yivo forced Shkler tentacles into everyone's necks and did that to everyone except Leila. Given the context of the situation, Yivo technically raped almost everyone in the universe. All of the people who got tentacles got very angry when they found out but their anger against Yivo quickly disappeared.
  • G.I. Joe: Renegades has several of its main baddies crossing this:
    • Cobra Commander's exact crossing is hard to pin down, but his general complete disregard for any innocent life lost in the process of any of his schemes makes him a pretty unambiguous monster.
    • Cobra as a whole crosses this in "The Anaconda Strain" where its revealed that they plan to release a disease they have made into populations and then charge high prices for the cure that Cobra also made.
    • Baroness crosses this in "Going Underground". When the Mook operating Cobra's underground tunneler protests that if they keep going at the speed the drill is going at, they will cause untold damage via seismic activity, what is Baroness' response? To electrocute him and then "thank" him for his "misplaced concern", wearing a Psychotic Smirk the whole time. Then she takes up control of the drill itself.
    • Mindbender crosses this in the episode "The Anomaly" when, after Tunnel Rat points out that, if the Bio-Vipers he rigged to self-destruct do blow up, the explosion they cause from igniting all of the flammable materials in the sewer will blow up all of Brooklyn. This is Mindbender's response:
  • Gravity Falls:
    • Gideon started out as a stalker who manipulated Mabel into being in a relationship with him, even though she likes him more as a little sister. Then he tries to cut Dipper in half with lamb shears. In-universe, Mabel decides she wants nothing to do with him after that.
    • The entire reason for the Lumberjack Ghost terrorizing the Northwest manor is because of Nathaniel's own MEH. Basically he demanded that the lumberjacks built a prestigious manor for him and in return, he will give them a grand party for them. This proccess cost the lives of many woodcutters and take a considerable effort to do. So what does Nathaniel do once the building is complete? He goes back on his promise and betrays them once its over, leaving away many upset builders and causing the death of a Corduroy worker but not before vowing to make them pay for what they done.
    • Preston Northwest was willing to let all his guests (including children and old handicaps) die at the hands of a vengeful ghost his family brought upon him just to uphold his own refined image. Not to mention mentally abusing Pacifica into becoming a jerk through Pavlov conditioning.
    • Filbrick, even though was only shown in a flashback, is shown to be an even worse Abusive Parents than Preston when he kicks out Stanley not because he ruined his brother's college dream but because he cost his family the potential to be rich. As much of a Rich Bastard as Preston is shown, at least he somewhat cares about his daughter or at the very least, never disowns her simply defying against his orders.
    • Although he's a more sympathetic example than most of the other villains, Grunkle Stan nearly crosses it in "Not What He Seems". His goal was to bring his long lost brother back from another dimension. Doesn't sound too bad, right? Well, he tries to do so by activating a very unstable machine which could have caused The End of the World as We Know It. And he was fully aware of it. Thankfully it doesn't come to that, but the very fact he was willing to take such a huge risk was enough to even make Soos turn on him.
    • When he first appeared in Season 1, Bill Cipher was interpreted as a Punch Clock Villain who enjoys his job a bit too much. But Season 2 arrives and we see Bill for the true monster he is. In his reappearance, he tricked Dipper into a deal to possess him and then proceeds to torture his body to the point of being hospitalized and nearly tricks Mabel into either handing over the journal to be burnt or fall down and ruined her puppet play. As if that weren't enough, he threatened to murder the same children unless Ford gives him the code to breaking the barrier keeping him and his creatures in Gravity Falls.
  • In season 3 of Jem, Eric Raymond crossed it when he destroyed the master tapes to the music of Jacqui Benton, Jerrica's mother.note  Instead of meeting either Eric's demands (either one million dollars for the tapes or controlling interest in Starlight Music), Jerrica asked that Eric just return them, hoping that there was still some shred of humanity left in him...
  • Justice League: Some - if not all - of the many things that the Justice Lords (Knight Templar counterparts of the League) did in "A Better World". Lord Green Lantern attempts to kill JL Green Lantern immediately rather than disarm him or knock him out.. Also, when Lord Wonder Woman knocks League Batman down, she picks up a chunk of building rubble to finish him off. From the DVD commentary, the writers did that on purpose so that it showed that the Justice Lords while having good intentions, they ultimately are truly heroes turned villains who deserve to be defeated.
    • In the same episode, Lord Superman had Flash by the neck with Flash trying to appeal to any remaining good in him. Also, the Flash in their world had been killed and his death was one of the main reasons why they all became such cynical Knight Templars. However, Lord Superman, referring to moral lines he never thought he'd cross, coolly told him that "one more won't hurt", that this universe's Flash's death was just another means to an end. This contrasts him with the more-redeemable Lord Batman, who is visibly horrified when he thinks Flash's heart has stopped.
      • The true Start of Darkness is probably when Superman kills Lex Luthor, who was elected president. However, it is ambiguous since Luthor was about to hit the Big Red Button, probably to start a nuclear war. Afterwards, even Batman says that Supes made the right decision.
    • Minor villain John Dee in the episode "Only A Dream", where he "operated" on his wife in her dreams, torturing her until she died of fright, shortly after he had found out that she was planning to leave him for another man.
    • Orm tried to kill his brother's infant son. His brother did not take it well. At all.
      • He didn't only try to kill his own brother's infant son. He put both his brother and said brother's infant son in a Death Trap. And the only way to save them both was Papa Wolf!Aquaman mutilating himself to do so.
    • Project Cadmus practically made a habit of doing this, even as they claimed they only had the good of the world at heart. Abducting metahuman children and youths to rear them as super soldiers, genetically engineering metahuman super soldiers and not only not caring that the process is unstable and so the clones inevitably die after a few weeks, but seeing that as an actual bonus, creating Doomsday, cloning Supergirl and then using the clone as a Super Soldier and assassin to keep their agenda secret, attempting to nuke an island with a kryptonite-based atomic missile in the hopes of killing off Superman and Doomsday in one shot, sending a team of supervillains to steal a magical superweapon from the Justice League's headquarters, working with freaking Lex Luthor to discredit and aggravate Superman... Yeah, Villain Has a Point that the Justice League could potentially take over the world... but, on the other hand, Cadmus does a hell of a lot more actual damage to the world than the Justice League ever does.
  • Mr. Cat from Kaeloo crossed this in the episode "Let's Play Gangster Poker", where he threatened to shoot Kaeloo and Quack Quack, who are supposed to be his best friends, unless they gave him money that he tricked them into thinking they owed him (in other words, which they didn't even owe him).
  • Kim Possible
    • Monkey Fist crossed it in the fourth season. Attempting to murder and/or kidnap a child is bad enough, but he made a Deal with the Devil, or rather, a demonic monkey being in order to command it. Some could say that his Taken for Granite death was well deserved.
    • Warmonga and Warhok in the Grand Finale were about to kill Kim and stuff her as a trophy back to their home.
  • Floyd and Jolene, the villainous gators on Kissyfur, usually resort to trickery and being sneaky in order to catch Kissyfur and his friends for dinner. However, they cross the line BIG time in "The Birds and the Bears" when they steal Gus's paddlecab, which Kissyfur and three of his friends took a ride on with Miss Emmy Lou's niece Donna to prove that they were "cool", and trick Gus into following them so they can lure him into quicksand to drown and die while they use the paddlecab to catch Donna and some of the other critters for dinner. As expected, they get their just desserts after Kissyfur, Beehonie, Toot, and Miss Emmy Lou free Gus from the quicksand and soon free the captured critters and retrieve the stolen paddlecab.
  • Kung Fu Panda: Legends of Awesomeness, despite being Lighter and Softer than in film, has several villains that went too far.
    • Temutai, the king of the Quidahn, enslaves children and they always die in a few years. The only thing redeeming about him is the fact that he's a man of his word.
    • Hundun crosses this by threatening to kill Po's father just to force him to fight him. This also makes things personal for Po.
    • Tong Fo counts too, wanting to destroy the Valley of Peace for no apparent reason.
    • Ke-Pa crosses it when he temporarily killed Po.
  • Disney's The Legend of Tarzan has Professor Philander, rival and Evil Counterpart to Professor Porter has the same goofiness and is generally a Harmless Villain most of the time, until he went from silly to downright irredeemable when he cuts a rope where Tarzan's hanging on, sending him to fall to his apparent death. To make matters worse, rather then letting his rival check on his son-in-law, he then plans to strand him into the sea and throw Tarzan overboard just to spite his rival.
    • Lt. Colonel Staquait crossed it by ordering Hugo and Hooft to burn a village full of mostly innocent women and children.
  • Daffy Duck crosses the MEH in the The Float. He takes every cent of Porky's money, saying he needs it for a kidney operation. After going bankrupt, Porky eventually discovers that Daffy used the money to buy a yacht and attacks him for it.
  • Dr. Rockso, one of the most popular characters in Metalocalypse, crossed this when he stole the Christmas presents Toki got for everyone, hocked them for cocaine money, then received a handjob on live television while bragging about his drug addiction, and getting Karma Houdinied because Toki experienced Diabolus ex Machina before he could beat up Dr. Rockso.
    • Mr. Salacia crosses in the two-part season 4 finale, in which he brutally murders Roy Cornickelson, the elderly head of Dethklok's record label and one of the few completely good characters in the show.
  • Clay Puppington crossed the line in "Nature part 2" the moment he shot Orel, his own son, in the leg. How does he feel about it? No regret. Even if there are two episodes showing of how did he become the bad father to be, there is no sympathy. The shooting is effectively the point where Clay stops abusing Orel through mere neglect and misdirection and becomes actively, maliciously obsessed with destroying the boy's innocence, just so he can prove to himself that his own misery is natural and not because Clay himself is horribly twisted inside.
  • Nurse Gazelle from My Gym Partner's a Monkey crosses this in "The Hyena And The Mighty" when she chases Rufus Hyena trying to shave his fur off. Doesn't seem too evil? Well, Rufus was in a state of shock and depression and was busy crying his eyes out because Adam insulted him. The nurse doesn't care about Rufus' feelings or emotional well being, she outright TERRORIZES him while he's in a sad mood by chasing him with clippers just so she can make herself laugh. Also, keep in mind that Rufus is only a kid and would most likely get emotional scars from the incident. Sure, no blood was shed but the psychological trauma poor Rufus Hyena has to endure is just sickening and gut-wrenching. From the same episode Adam Lyon pretty much jumps off the slippery slope when he not only insults Rufus Hyena and doesn't care about him when Windsor explains he may be dying but near the end of the episode, Adam threatens Rufus with physical violence if he doesn't stop crying, despite Adam being the one who made the poor hyena cry in the first place. It is by far one of the most evil things Adam has done. It's a good thing karma catches up to him in the end.
    • Nurse Gazelle gets away scot-free, but it could be argued that Adam deserved it more for starting the whole serade in the 1st place.
    • Jake Spidermonkey crosses it in "Poop Scoop" where he tries to save the school paper by repeatedly slandering his supposed best friend Adam with false rumors of romantic involvement with various female faculty members. What's worse is despite getting what he wanted (He only uses the newspaper as TP), he continues to slander Adam For the Lulz!
  • My Little Pony: Friendship Is Magic:
    • In Dragon Quest, the adolescent dragons, who are initially portrayed merely as obnoxious Jerkasses, bring Spike along on a "raid" that involves stealing phoenix eggs away from their parents and smashing them, simply because they think it's fun. They don't change their minds when the newborn babies hatch, either.
    • In A Canterlot Wedding, Imposter-Cadance/Queen Chrysalis crossed this by leaving Twilight trapped in the mines under Canterlot which were long forgotten so nopony would ever find her. Then taunting her with that fact, just to rub it in. And then it's revealed she did the exact same thing with the real Cadence, who is in rough shape by the time Twilight finds her. All this after letting an already-broken and regretful Twilight think all is forgiven. If not then, she crosses it in To Where and Back Again when it's revealed she had been willfully and deliberately starving the other changelings just to maintain control over them and only further herself and attempted to drain all of the love from Thorax for his betrayal just to further stroke her delusional leadership.
    • The Crystal Empire does this to King Sombra immediately upon his introduction, in which it is revealed that he used Black Magic to turn the Crystal Empire into Mordor and enslave the crystal ponies who lived there. Worse still, he's given no excuse for his crimes - Nightmare Moon had a tragic backstory, and though it doesn't remotely excuse their actions, Discord and Chrysalis were at least motivated by some component of their natures. Sombra, though, was just a regular unicorn who decided to seize power for himself even if it meant ruining the lives of everyone around him. Appropriately, the episode presents him more as a monstrous force of evil than as an actual character.
    • In Twilight's Kingdom Part 2, if Lord Tirek hadn't crossed this already, he certainly did when he imprisoned Applejack, Rainbow Dash, Pinkie Pie, Fluttershy, Rarity and Spike, drained their magic, betrayed Discord, and drained him of his magic. Even earlier than that, he banishes Celestia, Luna, and Cadance to Tartarus, even though they have no magic and are powerless to do anything against him.
      • Interestingly inverted with Discord. In "The Return of Harmony", he almost crossed it by mind raping the main cast. A few seasons later, after taking a level in kindness, you'd think betraying all of Equestria to Tirek, including Fluttershy, would count as this, but due to his recurring remorse and reaction to Tirek betraying him not only make him sympathetic, but solidify his Heel–Face Turn.
  • The Powerpuff Girls:
    • Dick Hardly crossed the MEH when he kills a Buttercup clone for its Chemical X. He crossed it even further when he attempts to murder the real Girls for their own Chemical X and forcing the Professor to watch.
    • Mojo Jojo in the movie when he enslaves the entire city of Townsville with his monkeys, destroying most of the city, and also breaking the Girls' trust.
    • Him crossed the line in "Speed Demon" during a Bad Future where he took over Townsville, turned it into a post-apocalyptic place, and made the Townsville citizens all depressed and zombielike.
    • Princess crossed this In-Universe during "'Twas the Fight Before Christmas" after she switched the Naughty and nice List to make it seem like the Nice kids were the Naughty ones, and vice versa for the Naughty kids, to make it seem as if she was the only nice child on earth. When Santa finds out, he places her on "The Permanent Naughty Plaque".
    • Mitch Mitchelson torturing and flushing Twiggy the hamster down the toilet in "Getting' Twiggy With It".
    • Buttercup almost crossed this after she remorselessly made Bubbles cry by breaking the latter's chalk in "All Chalked Up". This is ultimately subverted when it's hinted that Buttercup felt bad later on in the episode, and gives an implied apology to Bubbles.
      • However, it was agreed by plenty of viewers that Buttercup crossed the line long ago before that episode when she abused Bubbles to steal her teeth and ended up stealing teeth from the villains just to get money from that in "Moral Decay".
  • Phineas and Ferb:
  • Bluto from the Popeye cartoons crosses the line in almost every episode whenever he harms Olive Oyl after she rejects him, which includes kicking Olive off a runaway roller coaster in Abusement Park and trapping Olive in a straight jacket and then approach her menacingly in The Royal Four Flusher.
  • The Raccoons: Milton Midas ultimately crosses the line in "The One That Got Away" by having the pigs dump toxic waste into a beloved fishing hole which is a favorite among some of the Evergreen Forest's residents.
  • At the end of the second season of ReBoot, Megabyte and Hexidecimal team up with Bob to stop the Web Creature invasion. However, near the end of the episode Megabyte launches Bob into the Web and takes over Mainframe.
  • Recess: In the episode "The Biggest Trouble Ever" the Recess Gang accidentally breaks the statue of Thaddeus T. Third III, the namesake of Third Street school, thus becoming hated by the entire town. They are labeled "The Destructive Six" and are given menial jobs by Principal Prickly and Ms. Finster as punishment. It goes too far when Mayor Fitzhugh and the City Council decide to send the gang to six separate schools, despite the fact that they broke the statue by accident and were genuinely remorseful. This shocks everybody (even a shocked Prickly and Finster think that this punishment is way too extreme). Luckily, Thaddeus T. Third V (grandson of Thaddeus T. Third III) called the Mayor out on this and revealed that Fitzhugh intentionally tried to break the statue when he was a child. Most of antagonists in this series are jerks, but Fitzhugh's hypocrisy is notable.
    • Benedict's plan, if you apply Fridge Logic to it, involved moving the sun away to have "no more summer"; would've killed all life due to extreme freezing conditions.
    • Dr. Slicer was already cruel and heartless, but when he demanded the cannon to be functional, he really showed his un-hidden dark side.
  • Regular Show:
    • Night Owl seems like your average Disc Jockey at the time, typical boorish and obnoxious behavior. However, he soared to irredeemable when he held the contest with a prize of a vintage muscle car for the last person standing on top of a huge billboard. When he discovered Mordecai, Rigby, Muscle Man, and High-Five Ghost are planning to share if they won, he froze them in liquid nitrogen for at least two millennium. After the gang thawed out, they found out that Night Owl had no intention of freeing them and meant to kept the contest going forever! In a show where Eldritch Abominations are the norm, a normal human being can be quite monstrous due to his Greed.
    • Klorgbane crossed when he destroyed Skips' high school prom, knocked out the principal, and got Skips' girlfriend, Mona killed in the crossfire just so he could fight Skips.
  • Samurai Jack
    • Aku, the Big Bad of the series is considered to be evil personified. He crosses the MEH in the very first episodd when he decimates Jack's hometown, leaving his father's kingdom in ruins.
    • The High Priestess is shown to be a very abusive mother towards her own seven daughters, giving them no love and affection whatsoever as she instead puts them through brutal and rigorous training just so they would be able to kill Jack and in doing so glorify Aku. Her MEH moment comes in the sixth episode of the final season when she pushes her own daughters into a pit of burning coals, which out them in severe pain, burnt the majority of their skin and caused such skin to serve as their battle suits.
  • Scooby-Doo! Mystery Incorporated:
    • Mayor Jones asks the kids to come to the Cicada Festival, saying he has a plan to protect them. He actually wants photos of them being overwhelmed by swarms of bugs for tourism purposes. And he gets worse: How about kidnapping a baby from people he knew, forcing said people to leave town by threatening to hurt said baby, and feeding him lie after lie as he grew up? Oh, and he's the Freak of Crystal Cove and thus is the cause of EVERY SINGLE THING that happened to the original and current Mystery Inc.
    • Multiple parents in episode 5, abandoning their "spookified" kids with the assurance that the government will air-drop in food. And it was entire blocks of parents.
    • Brad and Judy, Fred's real parents, willingly firing a missile at a helicopter that they know Fred is inside without any regard to his safety in "The Horrible Herd."
    • It's hard to determine with Professor Pericles, as he excels at committing horrific acts in almost all his appearances, especially toward the end of the show.
    • The Nibiru Entity gets one when, after it is freed proceeds to eat Brad and Judy (after they had pledged their servitude), then Mr. E., then the rest of the town, all for power (and you can tell it's enjoying it), and it claims it will go on to devour entire galaxies. Then again, it is the most evil Annunaki ever. As such, when Scooby strikes the final blow that destroys it forever, it is VERY satisfying to see it vainly struggle to escape its fate.
    • Of course, in the end of the series, none of these qualify as Moral Event Horizon crossings anymore... because they never happened.
  • In SpongeBob SquarePants, Plankton crosses the Moral Event Horizon in the movie. He stole King Neptune's crown, frames Mr. Krabs for it, enslaves Bikini Bottom, shows excitement and joy when Mr. Krabs is going to be executed and sends Dennis to kill SpongeBob and Patrick.
    • Of course, Mr. Krabs isn't exactly a saint himself considering how greedy he is, particularly during the Seasonal Rot. In "One Coarse Meal" he establishes his Seasonal Rot personality when he exploits Plankton's fear of whales by dressing as his daughter, Pearl, threatening to eat him. Krabs harasses Plankton so much, the latter eventually becomes suicidal. After Krabs found out that Plankton was ready to commit suicide, he simply laughed at Plankton's misery. Worst of all, apart from temporarily being hung upside down & forced to watch a mime's performance after Plankton finds out, he doesn't receive any comeuppance for this. And all of this is for fun.
    • In "Cephalopod Lodge", the members of the lodge crossed this when they kicked Squidward out just because they thought SpongeBob and Patrick were following him. It's made even worse when you realize the lodge was one of the things that made Squidward genuinely happy in his whole miserable life.
    • In the episode "Demolition Doofus", Mrs. Puff crosses it with her attempt to kill SpongeBob in a monster truck derby when she got tired of his antics, even stepping in herself when he managed to prove himself a natural at it. Not just injure him, but kill him outright!
  • Many villains in Star Wars: The Clone Wars have crossed this:
    • Cad Bane, as fairly popular as he is, still crosses the line when he tortures a guy to death, on-screen no less.
    • Zygeerian Keeper Arguss wants to make sure Obi-Wan does not try to attempt anything against him, by dropping some Togrutan prisoners down a bottomless gorge. And then later, when the Republic has arrived to liberate the surviving slaves, he sets the system to dump the slaves into the abyss, and then smashes the panel to prevent Obi-Wan from saving them.
    • Osi Sobek crosses this when he gleefully shoots a captured Clone Trooper in the face.
    • The Trandoshan Slavers, what with their capturing and hunting Jedi Padawans, as in, teenagers, for sport.
    • Pong Krell, when he cruelly tricks 501st Legion and 212th Attack Battalion Clone Troopers into killing each-other before Rex realizes that they're being duped. Worst of all, among the clones killed is Waxer.
    • Pre Vizsla crosses this when he callously murders an innocent teenage girl in front of her father and then orders his men to torch the whole village. Why did he do all of this you ask? Because that aforementioned father and his people had demanded that the Death Watch give them back those among them who they had taken as slaves
    • Darth Maul takes a running leap over this in the fourth season finale. While most would argue that Maul had already crossed it when he killed Qui-Gonn, Qui-Gonn is a Jedi, Maul is a Sith. Nothing personal there. What is personal, however, is murdering a bunch of innocent people, including children, just to lure Obi-Wan for the sole sake of revenge. He may have also crossed it by killing Duchess Satine in front of Obi-Wan just to utterly devastate him.
  • While we already knew the Diamond Authority in Steven Universe weren't nice, what throws them into this trope is The Reveal of what they did in response to the Rebellion for Earth. They took the shattered remains of Rebel soldiers and used them to make tortured fusion monsters, putting the biggest one of all in the center of the Earth's core so that when it eventually took form, it would destroy the planet, and even refused to undo it when told Earth would be more useful intact because of the Rebellion winning the war and killing Pink Diamond. Even though as far as they knew the rebellion was gone because they corrupted all the remaining Gems on the planet into Gem Monsters before leaving.
  • Teenage Mutant Ninja Turtles (2003): Shredder's personal Moral Event Horizon comes in the episode "Mission of Gravity", when he orders his lieutenants to steal the Triceraton engine holding the city of Beijing aloft miles above the earth, despite the fact that doing so would naturally doom the millions trapped within it. It was possible to remove the engine without killing anyone, but he didn't care.
    • When Leonardo saves Karai from falling to her death, she stabs him from behind with his own katana when he would have let her go in the spaceship anyway. This is one of the things that leads him to tell her she is just as bad as the Shredder. It can be argued that every decent thing she did after that was just self-preservation.
      • Technically in that instance, Shredder punched him into the blade, which Karai held at that moment. If you look at it for a split second she's visibly shocked by what just happened. So in that case it's TECHNICALLY an accident.
    • Karai's alternate future self from "Same As It Never Was" aided Shredder and served him as his right-hand, even when Shredder took over the entire planet, turning it into a massive hellhole, enslaved humans and Utroms, planned to invade other worlds and reduced much of Earth's population and killed everyone who opposed him in brutal ways. Yet she still aided him and never even expressed any remorse for any of this, while stating that she just follows her duties, but at this point this argument to defend herself is meaningless. She is just as accountable for this as the Shredder. Karai from present at least questioned his acts and even went against him in "Mission Of Gravity" and pulled a Heel–Face Turn during the Turtles Forever, when she found out that Shredder was attempting to erase the entire universe.
  • In Teenage Mutant Ninja Turtles (2012) Shredder has a few candidates.
    • In his backstory, he burns Splinter's house and kills his family, simply because Splinter married the woman he was in love with.
    • In the first season, he allies himself with the Kraang, making a deal with them that would result in everyone on the Earth dead or mutated, just so he could get Splinter out in the open.
    • First season finale: It's revealed that Shredder didn't kill Splinter's daughter, Miwa, he kidnapped her and raised her as his own - Karai. Meanwhile, he fed Karai a lie that Splinter killed her mother, giving her a vendetta against Splinter as well. He's been using her as a pawn for revenge her ENTIRE LIFE, and she doesn't have a clue. And he doesn't hesitate to sic her on Splinter when she comes to help Shredder.
      • And when Karai learns the truth and asks him about it, he casually tells her yes then has her locked away in the dungeon without a second thought.
      • If he hadn't crossed the horizon with those acts, he certainly has by the end of the third season finale, where he literally backstabs Splinter in an Enemy Mine to save the Earth from a Black Hole Generator. At this point, it became clear that killing Splinter took precedent over everything else, including Karai's well-being, and as a result, the BHG activates and sucks the Earth into a black hole, killing everyone and everything. It takes this show's version of the Fugitoid/Professor Honeycutt saving the Turtles and going back in time to reverse this, and the second time, Splinter finally calls Shredder out for this, saying that he has been the monster all along.
  • In Thundercats 2011, the act that cements Mumm-Ra's evil happened in the backstory when, on the behest of the Ancient Spirits of Evil, he destroyed the Plundaar star system which was inhabited by billions to create the metal needed to forge the Sword of Plundaar. It even acted as one in-universe. This heinous act convinced Leo that Mumm-Ra was not the visionary bringer of order to the universe that Leo thought he was but a monster that needed to be stopped.
  • In Transformers Prime, Megatron, is revealed to have crossed the line multiple times back on Cybertron. Aside from instigating the very war itself, he developed a cybonic plague and a bioweapon out of toxic Energon, both of which wiped out most of the Autobots (and lord knows how many innocent Cybertronians) gradually turning the entire planet into the graveyard it is today. However, he arguably crosses the definitive line in "One Shall Fall", when he shoots Bumblebee with Dark Energon, nearly killing Raf in the process. While Megatron was unaware of Raf's presence at the time, his reaction later on establishes he has no problem inflicting off-world casualties. For Optimus, this was the last straw, as he saw no alternative than to destroy Megatron once this happened.
    • Airachnid crossed it millennia ago when she tortured Arcee and murdered Tailgate. Beyond that, we learn she's spent who-knows-how-many years hunting species and committing genocide. For fun. Whether this started before or after Tailgate's murder is unclear.
    • Silas crosses it when he works with Airachnid to kidnap June Darby and then shows he's willing to let Airachnid kill her and Jack, dismissing them as collateral damage.
    • In "Evolution", upon discovering Predaking's transformation, Megatron and his command staff plan the eradication of the newborn Predacon clones, before said clones are given the chance to turn on the Decepticons. Starscream suggests they set it up so the Autobots would look entirely responsible and turn Predaking's anger towards them instead of his creators. Even Shockwave, the creator of the clones, is coldly in favor of the idea, though that's in-character for him: he will always take the most logical decision available, be damned to the moral questions.
  • Hard to imagine that a show with silly villains like T.U.F.F. Puppy have someone crossing the line, rather it's not a villain but a former agent of T.U.F.F, Jack Rabbit. After he's been revealed that he betrayed T.U.F.F and lying to Kitty doesn't sound bad but his reason for his betrayal: Money! That's right, no Start of Darkness, no sad backstory, it was all due to his Greed.
  • The Venture Bros. Many of Dr. Venture's actions are examples of the sort that would normally qualify him for crossing it. He's the star of a Black Comedy, however, so it's more funny than repulsive thanks to much Refuge in Audacity.
    • Rusty, in the first episode, removes a dog's skin (his own dog no less) because a makeup company wanted to find a new way to test makeup on animals. To be fair, it was to prevent the dog from dying, but that's still pretty horrible.
    • It's pretty much telegraphed that Tim-Tom and Kevin killed 24.
    • Limb releases The Monarch's prison mates just so that he can hunt them down like animals.
    • Molotov Cocktease crosses this twice: first at the end of season three, where she puts a bounty out on Brock Samson's head and tricks him into thinking OSI was the one responsible. Manipulating Brock just to further her career was more impressive than it was unforgivable... but in Operation P.R.O.M., she went and not only chose someone else (Monstroso) over Brock after long acknowledging his affections for her, but was also willing to die with him. Then, just as a final "screw you" to Brock, she told him if she were to die, the Blackhearts were ordered to kill all of Brock's friends. They only survived because Dr. Venture used mutant Spanish Fly on them. Which turned them into mutant Spanish flies.
    • The senior Dr. Venture has done several things that may qualify. ◾ His actions once caused a group of orphaned children to wander below his home for over 20 years. One wonders if this is probably worse that his son's machine that was powered by the heart of an orphan.
      • On a more intimate level: acting as Rusty's therapist so that he could belittle his own son and tell him how ungrateful he was for not enjoying a life of constant danger, kidnapping, and isolation from his peers. If you didn't already think he was worse than Rusty, this about clinches it.
      • Creating an AI with full access to a nuclear silo was a pretty idiotic move to begin with. Not to mention he trapped the miniscule Dr Entmann in her control room for decades as well.
    • Dr. Impossible using his ex-brother-in-law, a failed experiment who is constantly on fire (and screaming in pain) when awake as a green energy source to power his skyscraper. It says something about him when he thinks being green makes it morally acceptable. The Phantom Limb says it's basically the most deliciously evil thing he's ever seen.
    • Monarch's had several, but they usually don't take with fans. Most notably, his forcing a prostitute to run a dangerous gauntlet inside the cocoon after they have sex was supposed to be one, but the sequence's Red Dragon homage and Monarch revealing that he stole the polar bear from Lost to serve as a guard-bear, made fans laugh at it instead.
    • In the season six premire, the Sovereign masterminds a plot to destroy the Gargantua 2 space station/casino hotel, to kill hundreds of the civilians on board so he can escape having to pay for his Deal with the Investors.
  • In Season 4 of Winx Club, Ogron, the leader of the Wizards of the Black Circle, got to this dreaded point of no return. After the Wizards pull their I Surrender, Suckers plan on the Earth fairies, Ogron tears open a portal to a nightmarish dimension to imprison all the fairies there. Aisha's boyfriend Nabu does an Heroic Sacrifice to close the dimensional gap, but loses his life in the process... and when the Winx try to use the Gift of Life to bring Nabu back, Ogron snatches it and casually casts it away, laughing all the way. This single act caused the distraught Aisha to join the Fairies of Revenge and separate herself from the Winx Club, and marked the point where the Wizards of the Black Circle sunk to a low no other Winx Club villain ever reached.
  • In W.I.T.C.H., you have a number of villains, but one who could easily stand out is Nerissa. Where Prince Phobos was already a Smug Snake, Nerissa started out as a normal woman, no, Guardian. But, she got a little too attached to the Heart of Candracar and was forced to hand it over to her dear friend Cassidy. When Cassidy refused to return it, Nerissa murdered her. She would spend the next generation plotting Phobos' downfall so she can take over, armed with as many Hearts as possible, going on a dog-kicking spree "for the good of the universe".
  • In WordGirl, the new villainess Miss Power crosses the line in her debut movie The Return of Miss Power. She severly curb-stomps the villains, and severly taunts them. She then teaches WordGirl to say mean words. She mocks the man who couldn't find the police station to the point where he cries, she manipulates the entire town into bullying each other, she gives WordGirl a No-Holds-Barred Beatdown when her plan for rule the Earth was discovered, and then gives her "The Reason You Suck" Speech. She even removes her star insignia. She throws Becky's mother into jail due to a disagreement that they had, and she tries to murder Dr. Two-Brains. Fortunately, WordGirl arrives just in time, and causes Miss Power to lose her power by not using mean words. She then has a Villainous Breakdown and leaves Earth.
  • X-Men: Evolution had one for most of the villains:
    • Pietro had his when he had a train derailed for the purpose of pretending to save people, and upon finding out that if they fail hundreds will die, including himself, he runs away and leaves those trapped, and potentially the entire town, to die. He knew his Brotherhood friends and his sister were there, and he left them there anyway;
    • Toad stole Kurt's image inducer — not that bad, until you remember that he purposely chose to do it while Kurt was meeting with his girlfriend Amanda's parents, ruining his chance at making them like him.
    • Magneto had it when he had his own daughter Wanda mindraped, just so she'd stay away from him. Said mindrape took place via replacing her memories of him abandoning her in a mental insitution, which is what made her become a Dark Magical Girl in the first place, into loving memories that made her forget his abuse;
    • Mystique when she tried to kill the New Recruits, for no reason other than them being unable to fight Magneto. And she did it again via kidnapping Scott, stealing his Power Limiter aka his ruby quartz glasses, and leaving him stranded in the middle of nowhere.
    • Duncan Matthews and his pals went from Jerk Jocks, to physically assaulting Scott unprovokedly after he was outted as a mutant, to post-graduation attempted mutant murder with mining machinery. That last one got them sentenced to life in prison. Duh.
    • There was also the soft-drink manufacturer who unknowingly laced his drink with mutant poison. You can tell he's genuinely surprised... then Mood Whiplash kicks in and he figures he can make a lot of money off the discovery.
    • Apocalypse was planning on using his machine to turn the populace into mutants... But even he notes that this may kill much of the human population, due to their bodies not being able to take it. He still was willing to go through it.
  • Rick and Morty: Rick himself crosses this at the end of the season three premiere when he (at great length) explains to Morty that all his of heroic actions throughout the episode were a calculated gambit to get Jerry and Beth divorced and allowing him to become the unchallenged family patriarch, and how Morty now has to go on all his adventures and can't do anything about it because Beth will hold him in higher regard for saving him and Summer. Assuming he's not lying about it though.
    • Tammy Gueterman crosses it in "The Wedding Squanchers" when after marrying Birdperson, reveals that her relationship with him was actually a Honey Trap set up by her and the Galactic Federation in hopes of crushing Birdperson's band of rebels who were fighting against the federation. Her MEH moment arrives when she murders Birdperson with a laser rifle after previously telling him to sit back down, which he refused simply because he didn't understand what Tammy was actually doing. Her actions in doing that furthermore endangered Rick's family and a bunch of innocent guests who attended the wedding. She even goes as far as to rebuild Birdperson into a cyborg in the beginning of Season 3 for her to use as a weapon
    • King Flippy Nips crosses it when he has his own son, Scroopy Noopers sent to Plutanamo Bay prison just because Scroopy Noopers protested against his fathers actions of drilling plutonium for riches, which was hurting Pluto itself.]]
