History MoralEventHorizon / WesternAnimation

%% Please put Disney examples in the Disney page.

* ''WesternAnimation/{{Arcane}}'': Jinx crosses it when [[spoiler:she kidnaps Vi and Caitlyn, and twistedly asks Vi to pick between killing Caitlyn or losing Powder as a sister. Vi isn't willing to go through with murdering her new friend, and then through mishaps Jinx accidentally kills Silco who tells her that she is perfect the way she is, cementing her as being Jinx for good. She tops off the ending by firing a rocket at the Piltover Council. Despite Vi trying to reach out to her in parts 2 and 3, the way she looks at Jinx in the end of Act 3 shows she concedes that Ekko and Caitlyn were right and Jinx is far too gone.]]

* ''WesternAnimation/{{Arthur}}'': [[CorruptCorporateExecutive Supreme Dog]] crossed it in the only episode he appears in, "To Eat or Not to Eat", by distributing [[GRatedDrug Big Boss Bars]], which are explicitly said to contain ''radioactive'' ingredients, in Elwood City and [[WouldHurtAChild marketing them specifically towards children]], all so that he can make a profit. Fittingly, at the end of the episode he gets sent to jail (presumably for life) for his actions.

* Red Skull from ''WesternAnimation/TheAvengersEarthsMightiestHeroes'' crosses this in season 2 where we find out that he [[spoiler: 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 [[spoiler: 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]].

** Even for the Joker, the events of ''Return of the Joker'' were extreme. He was already dangerous and psychopathic, but the very nature of how he did it turned him into. Not even Harley Quinn gets a get out free card after helping with that. [[spoiler: Although she survives anyways, [[WordOfGod thanks to her quasi-superpowered vitality after Poison Ivy made her nervous system immune to all poisons]] [[ContinuityNod back in]] ''[[ContinuityNod Batman: The Animated Series]]''.]]

** 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.

** 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, Skumm hands out a mind-affecting drug called "Bliss" to teenagers, deliberately causing them to go insane just for the joy of ruining their lives and those of their friends and families. [[spoiler: He even temporarily has Linka, one of the Planeteers, turned into a drug-addicted lunatic by her own cousin Boris, who had also become a drug-addicted lunatic and eventually dies from a fatal overdose of the drug, thus making Skumm indirectly responsible for Boris' death.]] And in the latter, he harassed an HIV positive teenager by spreading lies about HIV/AIDS because the kid was an easy target for him to use along with the naivety of the townspeople about HIV/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 MoralEventHorizon 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 UsefulNotes/WorldWarII and decided to sell nuclear bombs to '''Hitler''' (sure he was CaptainErsatz 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.

** 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.

** {{Gr|eaterScopeVillain}}andfather was also the one who's responsible of making Father who he is. He somehow [[FridgeHorror traumatized his own son]] into being scared of broccoli.

* ''WesternAnimation/TheFairlyOddparents'' movie "Wishology" has the [[TheDragon Lead Eliminator]] trying to kill Timmy is bad enough. But when he became the Destructinator, he plans to [[KillEmAll destroy]] the world in a EarthShatteringKaboom.
** 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 ForTheEvulz.
** Vicky crossed this in "Open Wide and Say Aaagh!" when she attempts to perform a "twerp-ectomy" on Timmy, which involves not only ripping out his tonsils, but also ''killing him''.

** Remy Buxaplenty was originally a VillainyFreeVillain 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 LonelyRichKid to full-on CardCarryingVillain as of "Operation F.U.N." where he, Juandisimo and Chief Shallow Grave put Timmy and his friends through TrainingFromHell, 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!

** In "[[Recap/FamilyGuyS9E16TheBigPangTheory The Big Bang Theory]]", Bertram tries to prevent Stewie's existence by going back in time and killing his ancestor, Creator/LeonardoDaVinci. This is bad, because Stewie [[StableTimeLoop accidentally caused the Big Bang.]] When Stewie warns him of this, he decides to kill da Vinci anyway. If it wasn't for MyOwnGrandpa, Bertram [[TemporalParadox would have]] [[OmnicidalManiac erased the entire universe]] [[RetGone and history itself.]]

** Cobra as a whole crosses this in "The Anaconda Strain" where its revealed that they [[spoiler:plan to release a disease they have made into populations and then charge high prices for the cure that Cobra also made.]]

** 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 soldier}}s, genetically engineering metahuman {{super soldier}}s 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 SuperSoldier 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 ComicBook/LexLuthor'' to discredit and aggravate Superman... Yeah, VillainHasAPoint that the Justice League could potentially take over the world[[note]]Unaware that they recruited ComicBook/GreenArrow as their political conscience who was able to keep them from overreacting to Cadmus' antics[[/note]]... but, on the other hand, Cadmus does a hell of a lot more actual damage to the world than the Justice League ever does.

* Disney's ''WesternAnimation/TheLegendOfTarzan'' has Professor Philander, [[TheRival rival]] and EvilCounterpart to Professor Porter has the same [[LaughablyEvil goofiness]] and is generally a HarmlessVillain most of the time, [[NotSoHarmless 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.

*** While [[BigBad Hawk Moth]] (a.k.a. Gabriel Agreste) came close to crossing the line before (such as in "Riposte", where he akumatized someone with a direct grudge against his son), his EvenEvilHasLovedOnes status just barely kept him out of irredeemable territory. In "Chat Blanc", however, he loses even that one redeeming quality. [[spoiler:First, his reaction to Adrien and Marinette's relationship is to blackmail Marinette into breaking up with Adrien (with [[SadisticChoice the threat of taking Adrien away from his friends]]) so that he can use the resulting pain to akumatize her, not caring that he's breaking his own son's heart in the process. Then, when Adrien transforms into Chat Noir in front of Marinette to save her, he is informed of this by his assistant [[TheDragon Nathalie]]. Hawk Moth then exposes his identity as Chat's father during their next confrontation, and then reveals that Adrien's mother is still alive and that he's trying to steal the Miraculouses to heal her. Gabriel then takes advantage of his son's conflicted emotions to akumatize ''him'', and then tries to force the newly akumatized Chat Blanc to kill Ladybug, causing him to FreakOut and [[ApocalypseHow accidentally kill all of Paris, as well as destroying the Moon]].]] The fact that the resulting BadFuture is later prevented from occurring does not change the fact that Gabriel's pretensions of EvenEvilHasStandards are now worthless.

** [[AbusiveParents Clay Puppington]] crossed the line in "Nature: Part 2" the moment he shot Orel, his own son, in the leg. Not only does he show no remorse for it, but he later admits he's ''proud'' of what he did. 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.
** Cecil Creepler is considered to be the show's biggest monster after it's revealed that he [[SerialRapist raped countless women]], which includes Agnes Sculptham whom was impregnated by him.

** Night Owl seems like your [[DumbassDJ average Disc]] [[ShockJock 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, Night Owl not only turned them against each other, but while they were fighting, [[HumanPopsicle he froze them in liquid nitrogen]] for at least two millennium. After the gang thawed out, they found out that Night Owl had tricked them, had no intention of giving away the car, and had meant to keep the contest going forever so he'd become eternally famous! In a show where {{Eldritch Abomination}}s are the norm, Night Owl makes it clear that even a '''normal''' human being can be quite monstrous if sufficiently consumed with {{Greed}}.

** [[spoiler:Tammy Gueterman]] crosses it in "The Wedding Squanchers" when [[spoiler:after marrying Birdperson, reveals that her relationship with him was actually a HoneyTrap set up by her and the Galactic Federation in hopes of crushing Rick and his 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.]]

* ''WesternAnimation/SantaClausIsCominToTown'': If [[MayorPain Burgermeister Meisterburger's]] harsh rejection of Baby Kris when he shows up at his doorstop weren't despicable enough, then [[spoiler: his burning of all the children's toys in Sombertown square ''right before their eyes'']] certainly makes him eligible to cross the line.

* ''WesternAnimation/SpongeBobSquarePants'': The comics give us the BigBad of the Untidaled arc, an unnamed kraken, who is arguably the ''darkest villain in the comics.'' Why? Well, not only is he responsible for the draining of the water that kick started the arc in the first place, we later learn '''''[[spoiler:[[ImAHumanitarian HE EATS FISH!]]]]''''' That's right, the darkest villain ''ever'' in the comic series [[spoiler:eats Bikini Bottomites]], and he tries to force Mr. Krabs to [[spoiler:make him a giant Krabby Patty that will attract MANY unfortunate citizens into his jaws.]]

** Count Venamus crosses it seconds after his début appearance when he serves poisoned food infected with the virus to several virus warriors attending the new virus warriors convention and sits back to see them turn into rampaging monsters, which was eventually stopped by the Noobs. His status as an MEH crossers is set in stone when he tricks Memnock and Zenblock into opening his prison pod then tries to murder them by shoving them in the pod and then launching it into space before attempting to murder the noobs again and this happened after the main cast tried to get him to do a HeelFaceTurn.

* In ''WesternAnimation/WordGirl'', Granny May crosses the line of just how far she's willing to go to ruin WordGirl's life in "Bonkers for Bingo". She's an evil bitch who has no qualms of ruining people's lives.
** The [[EnfantTerrible Birthday Girl]] crosses this line when she's willing to frame Wordgirl, and even kidnapped Sally Botsford when her true colors are exposed. She even later threatened to destory the Earth during Earth Day because of her strong greed. She had to be reasoned with twice in order to do something generous so she can shrink to back to her normal size

** 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 DarkMagicalGirl in the first place, into loving memories that made her forget his abuse.

** Duncan Matthews and his pals went from {{Jerk Jock}}s, to physically assaulting Scott ''unprovokedly'' after he was outted as a mutant, to post-graduation attempted [[AddedAlliterativeAppeal mutant murder with mining machinery]]. [[spoiler:That last one got them sentenced to life in prison.]]

** Randy's undeniably far past the line by the end of "[[Recap/SouthParkS23E01MexicanJoker Mexican Joker]]," when he [[{{Gorn}} brutally]] kills many people with explosives (specifically, he kills anyone growing marijuana in their gardens), [[{{Greed}} because he wanted to have a monopoly on the local marijuana business.]] Unlike the other instances, Randy isn't reacting to a perceived threat nor is he simply acting as the metaphorical devil in the shoulder for someone else. He's directly murdering innocents for no reasons other than greed and spite. From this point on, he;s treated like a borderline VillainProtagonist whose family turns against him, and he commits even more violent acts for his business, which eventually lands him in jail.

--->'''Mindbender''':[[LackOfEmpathy "The Bronx can thank me later"]]

** [[TheEvilPrince Orm]], the estranged brother of ComicBook/{{Aquaman}}, tried to kill his brother's infant son Arthur Jr. Arthur Sr. did not take it well... [[PapaWolf At all]]. Primarily because aside from trying to have his own brother killed and taking control of his throne, Orm planned to lead a war against the surface-dwellers, using his own nephew as bargaining chip to ensure his sister-in-law Mera's cooperation, and not only did Orm try to ensure that Mera would never see her son again regardless... ''He put both his brother and said brother's infant son in a DeathTrap''. And the only hope PapaWolf!Aquaman had of saving both their lives was to ''essentially mutilate himself!'' Only having time to break his right hand free before he and Arthur Jr. began to slowly plummet towards the lava of the volcano they were shackled to, Aquaman was forced to use his metal belt buckle to ''sever his left hand'', which is later replaced with a prosthetic harpoon.

** The Misfits crossed it in "The Fan", where they cause poor Jerrica to have [[HeroicBSOD a *serious* mental breakdown]].

* ''WesternAnimation/MarthaSpeaks'': Mrs. Demson was at first shown to be a huge stereotype of a [[GrumpyOldMan Crankt Old Person]] But almost a few episodes after her debut, She immediately become Flanderized into being [[MisanthropeSupreme harsh to everyone she talks to]], always complaining about the littlest things, she hates all animals, and let's not talk about how she was willing to fake an allergy so she can she can [[KicktheDog treat patients horribly]]. She got her comeuppance by being forcefully discharged from the hospital. But still...

* ''WesternAnimation/SpongeBobSquarePants'':
** Plankton brainwashing and enslaving Bikini Bottom in The Movie. In addition, he was willing to have [=SpongeBob=] and Patrick killed so they won't foil his plan, having hired a hitman to do the dirty work.
-->'''Plankton''': Evil Plan Z is way ahead of you, baby. I've already hired someone to take care of those two. He's a vicious, cold-blooded predator!
** The comics gives us the BigBad of the Untidaled arc, an unnamed kraken, who is arguably the ''darkest villain in the comics.'' Why? Well, not only is he responsible for the draining of the water that kick started the arc in the first place, we later learn '''''[[spoiler:[[ImAHumanitarian HE EATS FISH!]]]]''''' That's right, the darkest villain ''ever'' in the comic series [[spoiler:eats Bikini Bottomites]], and he tries to force Mr. Krabs to [[spoiler:make him a giant Krabby Patty that will attract MANY unfortunate citizens into his jaws.]]

She even later threatened to destory the Earth during Earth Da because of her strong greed. She had to be reasoned with twice in order to do something generous so she can shrink to back to her normal size
** the villainess Miss Power crosses the line in her debut movie ''The Return of Miss Power''. She severly [[CurbStompBattle 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 [[ManipulativeBastard manipulates the entire town into bullying each other]], she gives [=WordGirl=] a NoHoldsBarredBeatdown when her plan for [[TakeOverTheWorld rule the Earth]] was discovered, and then gives her TheReasonYouSuckSpeech. She even removes her star insignia. She throws Becky's mother into jail [[DisproportionateRetribution 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 VillainousBreakdown and leaves Earth.

** Dr. Rockso, one of the most popular characters on the show, 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 Houdini}}ed because Toki experienced DiabolusExMachina before he could beat up Dr. Rockso.

* In ''WesternAnimation/WordGirl'', the villainess Miss Power crosses the line in her debut movie ''The Return of Miss Power''. She severly [[CurbStompBattle 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 [[ManipulativeBastard manipulates the entire town into bullying each other]], she gives [=WordGirl=] a NoHoldsBarredBeatdown when her plan for [[TakeOverTheWorld rule the Earth]] was discovered, and then gives her TheReasonYouSuckSpeech.

If it wasn't for MyOwnGrandpa, Bertram [[TemporalParadox would have]] [[OmnicidalManiac erased the entire universe]] [[RetGone and history itself.]]

** [[Recap/FamilyGuyS10E18CoolHandPeter Sheriff Nichols]] seems to be a {{jerkass}} sheriff at first, deciding to frame Peter Griffin and his friends so that they'll have to spend two weeks at a prison... but it quickly becomes apparent just how horrible he is when Peter discovers that he and the warden are never planning to let them go.

You think CartoonishSupervillainy is nothing to worry about? ''[[WesternAnimation Think]]'' '''[[MoralEventHorizon again]].'''

* ''MoralEventHorizon/{{Disney}}''

** Duncan Matthews and his pals went from {{Jerk Jock}}s, to physically assaulting Scott ''unprovokedly'' after he was outted as a mutant, to post-graduation attempted [[AddedAlliterativeAppeal mutant murder with mining machinery]]. [[spoiler:That last one got them sentenced to life in prison. [[WhatAnIdiot Duh]].]]

** [[spoiler:Rick himself]] crosses this at the end of the season three premiere when [[spoiler:he ([[TheReasonYouSuckSpeech 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 [[UnreliableNarrator he's not lying about it]] though.
*** [[spoiler:Rick]] may have crossed the MEH earlier [[spoiler:in "Rick Potion #9", after he gives Morty a love potion that ends up causing everyone to turn into monsters. Instead of finding a cure for these people (after three failed attempts only made things worse), Rick simply takes Morty with him and abandons their dimension, moving into a replacement dimension where the problem was already solved... at the cost of said dimension's native Rick and Morty dying horribly. Rick and Morty end up seamlessly replacing their deceased counterparts who are both buried in the backyard, and Morty is left visibly traumatized by the transpired events.]]

** In "One Crew over the Crewcoo's Morty," one of Rick and Morty's adventures is ruined when a GentlemanThief steals a treasure before they can obtain it, and when called on it the thief challenges Rick to a "heist-off." Rick uses a robot called Heistotron to win the heist-off, but Heistotron goes berserk and escalates to stealing entire planets. Rick saves the day, but Morty is so disillusioned that he gives up his dream of selling a heist movie script to Netflix. Except [[spoiler:Rick was orchestrating nearly everything that happened, including Heistotron wiping at least one entire inhabited ''planet'', to make sure Morty gave up his dreams without it being traced back to him.]]

* In ''WesternAnimation/WordGirl'', the new villainess Miss Power crosses the line in her debut movie ''The Return of Miss Power''. She severly [[CurbStompBattle 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 [[ManipulativeBastard manipulates the entire town into bullying each other]], she gives [=WordGirl=] a NoHoldsBarredBeatdown when her plan for [[TakeOverTheWorld rule the Earth]] was discovered, and then gives her TheReasonYouSuckSpeech.

Fortunately, [=WordGirl=] arrives just in time, and causes Miss Power to lose her power by not using mean words. She then has a VillainousBreakdown and leaves Earth.

** Some--if not all--of the many things that the Justice Lords (KnightTemplar 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 [[WordOfGod DVD commentary]], the writers did that on purpose so that it showed that the Justice Lords while having [[WellIntentionedExtremist good intentions]], they ultimately are truly [[FallenHero heroes turned villains]] who deserve to be defeated.

[[caption-width-right:350: "Just for old times' sake, let's play... '''''uncle'''''".]]

** [[TeensAreMonsters Lila Rossi]] crosses the line in "Oni-chan", where, despite not being the MonsterOfTheWeek, she cuts a deal with Oni-chan to kill Ladybug, vowing to give up her pursuit of Adrien if Oni-chan does so [[note]]the horn that Oni-chan gave Lila does not grow when she says this, indicating that her crush on Adrien is overshadowed by her hatred of Ladybug, meaning that the former can probably be ruled out as a redeeming quality[[/note]]. After that, she fakes a leg injury, forcing Chat Noir to carry her away from the battle to give Oni-chan a better shot at killing Ladybug. Note that her hatred of Ladybug [[EvilIsPetty is because the latter]] [[LiarRevealed called her a liar in front of Adrien]] -- whom she was [[IResembleThatRemark actively lying to at the time]]. Adrien (Chat's alter-ego) certainly sees this as an in-universe MoralEventHorizon -- after the battle, he (in civilian guise) tells Lila that he wants nothing to do with her (that was after he was willing to tolerate her compulsive lying, despite his obvious discomfort).

** Eyeball (one of the Homeworld Rubies) crosses it in "Bubbled" when she finds out Steven has Rose Quartz's Gem. Unlike Jasper's breakdown, which occurred two episodes earlier, Jasper is [[UndyingLoyalty loyal]] to Homeworld and her thirst for vengeance is justice for Pink Diamond's murder; there is an a tragic undercurrent to Jasper's downfall. As Eyeball mentally cracks, she draws out her weapon to ''disembowel'' Steven and take his gem; not for justice for the Diamond she witnessed the brutal murder of, but for {{Greed}}. She starts muttering she'll go down in history despite the fact Homeworld '''has no knowledge''' of her plight. [[{{Lust}} She even gleefully wonders if she'll be given a Pearl]].

** Chloé Bourgeois crossed it in the two-part season 3 finale by [[spoiler:joining Hawk Moth, getting akumatized willingly and selling the other heroes out just because Ladybug didn't come to give her the Bee Miraculous when she wanted it, and ultimately feeling no remorse for it afterwards.]]
*** The fourth-season episode "Sole Crusher" effectively cements her as an irredemable two-dimensional antagonist, by having her actively explain her toxic and sociopathic lifestyle as some kind of twisted virtue. She abuses people for momentary satisfaction, treats her father and her best friend Sabrina as tools, and literally sees every other person besides herself as nothing more than pawns and props to use. (Even her own "Adrikins" is just there to make her look good.) When the title villain comes after her, she shoves innocents in her path just to get away and even leads the villain to the party barge just so her classmates can fall victim to Sole Crusher. The episode also introduces her half-sister Zoe, who is a significantly more likable person. A later episode [[spoiler:has Zoe take over the role as Bee Miraculous holder, which means that that option to return to heroism is cut off for Chloe as well]].
