History DownerEnding / WesternAnimation

* ''WesternAnimation/ThePowerpuffGirls'':

* A rare example for a PreschoolShow, but the ending of the ''WesternAnimation/LittleBear'' episode "Little Bear's SweetTooth" has the title character getting a stomach ache after eating too much dessert during the Harvest Day picnic. He is also unable to participate in the pie eating contest. After his parents tuck him to bed for the night, he hallucinates the moon as pumpkin pie and tells his 'sweet tooth', "No thanks, maybe tomorrow."

* ''WesternAnimation/RegularShow'''s season 4 finale had a major TearJerker. Margaret admits that she loves Mordecai, but then shows him the letter of acceptance to her dream school. Believing she may never have another chance like this again, she [[DidNotGetTheGirl declines Mordecai's offer to be his girl]] and runs out the door sobbing.

** Most prominently in "I Remember You", which simply ends in tears (both the character [[TearJerker and the audience]]) and features one of the most cruel and brutally honest examples of SurprisinglyRealisticOutcome ever, and "''The Lich''" (notably, a season finale), which ends with the heroes discovering that they just did exactly what the BigBad wanted them to.

** The first season finale [[Recap/AmericanDragonJakeLongS01E21TheHunted "The Hunted"]] ends with Rose having learned Jake's true identity and spares his life. At first, it seems as though Jake has a new ally in his love interest. But out of the blue, he learned from Principal Derceto that she's transferred to a new school, thus a picture of her and Jake was left. [[TearJerker Many tears were shed.]]
** The episode [[Recap/AmericanDragonJakeLongS02E18TheLoveCruise "The Love Cruise"]] also applies to this. Rose breaks up with Jake (at least for the time being), breaking both his heart and her own. In the final scene, Cupid returns to Gramps' shop to find Jake depressed and gives him [[HeartbreakAndIceCream chocolates and heartbreak "butter-butter" ice cream.]] Once he leaves, Gramps rushes in and says to Jake there is a griffin rampaging in the city. So Jake "dragons up" and flies outside as the episode ends with a close-up of a picture of Rose. [[HereWeGoAgain Again, so many tears were shed.]]

* The ending of the ''WesternAnimation/LittleBear'' episode "Little Bear's SweetTooth" has the title character getting a stomach ache after eating too much dessert during the Harvest Day picnic. He is also unable to participate in the pie eating contest. After his parents tuck him to bed for the night, he hallucinates the moon as pumpkin pie and tells his 'sweet tooth', "No thanks, maybe tomorrow." [[TearJerker Tears were shed at this point.]]

* In the end of the opera-themed ''WesternAnimation/LooneyTunes'' cartoon "What's Opera, Doc," Elmer Fudd has "killed the wabbit," and the dead WesternAnimation/BugsBunny gets up so he can do a bit of LampshadeHanging: "What did you expect in an opera, a happy ending?" It's true: most famous operas have {{Downer Ending}}s.

** The episode "Nerves of Steal". Buster is grounded for a month after revealing to the owner of the drugstore that he stole a Cybertoy.

* WesternAnimation/TomAndJerry, surprisingly, has a few of them:

* WesternAnimation/TomAndJerry:
** Would you believe there was an episode of WesternAnimation/TomAndJerry ("WesternAnimation/BlueCatBlues") that ended with them both sitting on a train track waiting to commit suicide by train? And just as it irises out, you hear the sound of a train whistle? Chilling.

** [[Recap/RickAndMortyS2E3AutoEroticAssimilation "Auto Erotic Assimilation"]]. Rick runs into an old lover of his, [[AnythingThatMoves an alien hive mind named Unity]]. It ends when Summer convinces Unity that Rick is a bad influence on her, causing her to leave him and Rick to attempt (and fail) to commit suicide.

[[folder:Marvel]]
* Thanks to it being unexpectedly canceled, ''WesternAnimation/SilverSurferTheAnimatedSeries'' ends with the Silver Surfer apparently dead and the universe destroyed.
* In ''WesternAnimation/IronManArmoredAdventures'', a HUGE one comes in "Ghost in the Machine" - [[spoiler: Ghost steals the specs to the Iron Man armor AND finds out that Tony is Iron Man. Afterwards, he sells the specs to Stane AND Hammer. To top it all off, Ghost plans on blackmailing Tony when he gains control of the company and Tony can't do anything to Ghost because he made it so if anything happens to him, Tony's identity goes global. Also, [[ArsonMurderAndJaywalking Tony didn't patent his armor.]] ]] Big downers all around.
* ''WesternAnimation/SpiderManTheAnimatedSeries'' has an episode that shocked us with its combination of Downer Ending and WhamEpisode. Mary Jane and Peter had finally gotten married at the beginning of the season, after MJ had been lost down a inter dimensional portal and come back. They are starting their honeymoon when Hydro-Man kidnaps MJ right under Peter's nose. He manages to find her again, only for it to be revealed that both Hydro-Man and MJ are in fact clones, made from a process that hasn't been perfected yet. MJ ends up disintegrating in Peter's arms. Even worse, when you realize that this means the real Mary Jane has been floating in the interdimensional portal all this time. These two episodes left many in a state of shock for hours. The remaining 5 episodes managed to turn it into a BittersweetEnding as Spider-Man saves reality itself from being destroyed... but Mary Jane is still missing.
* Similarly, ''WesternAnimation/SpiderManUnlimited'' ends with Spider-Man lost in time, the symbiotes spawned from Venom and Carnage taking over the city, and everyone is apparently powerless to stop them. An ending was scripted to have them overcome the infestation and Spider-Man, Eddie Brock, and Cletus Kasady making their way back to our Earth, but the series was canceled at that point.
* ''WesternAnimation/TheSpectacularSpiderMan'' ends with our hero triumphing over evil. All is well, right? Well, Norman Osborn is believed dead by most of the cast and longtime childhood friend-turned-villain Eddie Brock is locked up, most likely in Ravencroft, along with John Jameson. Curt Connors has been blackmailed into leaving ESU by Miles Warren, leaving Warren to help nurture Gwen Stacy and Peter Parker's scientific skills. Mark Allen, the Molten Man, is still not in control of his power-switch, and will likely continue to be blackmailed in to doing other people's bidding. Tombstone is walking free (albeit being monitored now). The Venom symbiote is still loose somewhere in the New York sewer system. Mysterio is still running free after the one sent to prison was revealed to be another 'bot, Chameleon is still out there and Kraven is also still free to continue hunting after Spider-Man. In Peter's personal life, you have a heartbroken Liz Allen, who is too proud to show it as well as her brother, the aforementioned Molten Man, being in prison, which is no doubt affecting Mary Jane too. Possibly the biggest gut-punch though, is Peter and Gwen, who have finally told the other how they feel. It looks like they'll finally get together, until Harry takes after dear ol' dad and manipulates her into staying with him, leaving Pete alone. Damn.
** Gets even worse when realizing that the show was canceled without even resolving the ending. Double damn. ([[RunningGag Notice a recurring trend here?]])
** Harry's dad is dead, he overheard his girlfriend say that she loved his best friend since the 7th grade (implying she never loved Harry) and his best friend said he loved her too (so his best friend stole his girlfriend, which is worse as [[WellDoneSonGuy Harry]] [[GreenEyedMonster feels inferior to]] [[TheUnFavourite Peter]] [[AbusiveParents because of his dad]]. The only characters who don't have a downer ending are some of the villains, everyone at the Bugle except JJJ, [[JerkJock Flash]], Robbie and [[AlphaBitch Sally]].
* ''WesternAnimation/SpiderManTheNewAnimatedSeries'': The Gaines Twins tricked Spider-Man into believing his long-time love Mary Jane has been murdered by Kraven the Hunter, sending him on a RoaringRampageOfRevenge, that nearly ends with Spidey murdering Kraven in cold blood. After he figures out their ploy, Spidey goes after them to rescue MJ. In the ensuing battle, the twins pull another MindRape on him which leads to him accidentally harming an innocent. Said innocent? Indira "Indy" Daimonji - Peter Parker's intrepid new reporter girlfriend, and one of Spidey's few consistent supporters in the series. Thinking it's Roxanne Gaines, Spidey mistakenly drops her off a roof, which lands her in a (seemingly permanent) coma. Dozens of New Yorkers (including MJ) witness this, making Spidey Public Enemy #1, and giving J. Jonah Jameson all the ammo he needs to start a grassroots movement to run Spidey out of town. Peter is so wracked with guilt that he agrees. He goes after the Gaines Twins a final time, resulting in their deaths (and nearly his) via explosion. The next day, Mary Jane tries once more to rekindle things with Peter, relating her sympathy over him losing Indy and being let down by Spider-Man. Peter manages to reject her in an even more heartbreaking manner than the first movie, barely being able to look her in the eye. Harry has his hatred of Spider-Man "justified" after seemingly turning a corner when Spidey helped save Sally from Electro. To top it all off, Peter locks the suit in a brick-laden case and tosses it into the river. Given that the series was cancelled after this, it seems that Spider-Man's quest to honor his Uncle Ben has ended in an even worse failure than "The Night Gwen Stacy Died." So, to recap - Spidey "loses" MJ (TWICE!!), nearly MURDERS Kraven, puts his new girlfriend in a coma, has the entire city turn against him, basically kills the Gaines Twins, and is abandoned by the one person that needed him the most - PETER PARKER. This HAS to be the most depressing depiction of Spider-Man ever committed to the screen.
* ''WesternAnimation/WolverineAndTheXMen2009'' ends with Jean back, and the BadFuture averted. However, [[spoiler: [[DefrostingIceQueen Emma Frost]] [[RedemptionEqualsDeath is dead,]] [[UglyCute Squidboy]] and his mom are implied to be dead, due to a GoryDiscretionShot, a probable thousand or so of mutants have been slaughtered, Angel is still under [[ManipulativeBastard Sinister's]] control, and [[CrystalSpiresAndTogas Genosha]], the only completely safe haven for mutants, has been leveled. Oh and that whole, BadFuture averted thing I said earlier? Yeah, well there's a new one where Apocalypse is now dictator of the world.]] But hey, the producers set that up so it could all be resolved for season 2. I mean, [[TemptingFate there's no way]] [[ExecutiveMeddling the show]] [[ScrewedByTheNetwork will be cancelled]] [[CutShort on a cliffhanger this enormous]].
* Episode 4 of ''WesternAnimation/WhatIf2021'' focuses on an alternate Dr. Strange that lost his girlfriend Christine Palmer instead of the use of his hands. All the same events of ''Film/DoctorStrange2016'' still happen, but afterwards he starts delving into time travel in the hopes of saving her. But every attempt ends with her dying, as her death is a "fixed point in time" that can not be changed. When told this by The Ancient One, Strange defies her but she uses her own dark magic to split Strange into two timelines. One where he doesn't pursue time travel, and another where he learns about absorbing other beings to gain power. That Strange spends centuries absorbing others and becoming "Strange Supreme". Meanwhile, the other Strange sees that reality is falling apart and is warned by a psychic manifestation of the Ancient One that only he can stop it. However, Strange Supreme ended up too powerful and he absorbs his better half. Using his power to ensure Christine survives, but she is frightened by his appearance and reality falling apart. Strange Supreme realizes what he's done and pleads with Uatu the Watcher to help, but he can not. Reality ends up destroyed and Strange and Christine end up in a pocket universe only for her to fade away. Leaving Stephen Strange all alone for eternity...until episode 8 where Uatu returns and begs for Strange's help in stopping Ultron.

* ''WesternAnimation/BatmanTheAnimatedSeries'' had a couple of these:
** At the end of the episode “Mudslide”, Matt "Clayface" Hagen's structural integrity is slowly slipping away and his girlfriend and scientist Stella has almost completed a procedure that will allow him to stay in his human state whenever he wishes... until Batman appears and turns off the machine in a rather cold, [[UnintentionallyUnsympathetic unheroic moment]]. Admittedly Hagen had to hurt several people and steal the technology and Batman originally offered to help Hagen himself, as well as claiming "the lab boys will take it from here", from which we can assume they would continue and finish the procedure. The two fight it out of the laboratory and Clayface is doused in rain, further loosening his integrity until the pair are hanging from a cliff. Batman loses his grip of Hagen and he falls into the water before dissolving completely (although later episodes reveal he was, of course, NotQuiteDead). The episode ends on a wide shot of the cliff, Batman climbing up and helping an inconsolable Stella. The tragedy of it all is somewhat dampened by the fact that this is a ShoutOut episode: Dr. Stella[[note]]STEELLLAAAAAA!!![[/note]] hid her Frankenstein's lab in the Bates Motel, while Clayface himself resembles an Oscar statue.
** In the sequel to that episode (“Growing Pains”), the new Robin meets and becomes smitten with a cute girl who turns out to be an "extension" of the newly re-formed Clayface that accidentally developed a mind of her own. At the end of the episode she's forced to re-merge with her "father", and after Robin goes berserk on him demanding that he bring her back, Clayface can only inform him that "she" is simply ''gone''. Later when the police are listing what to charge Clayface with, Robin bitterly says "Murder."
*** Batman even solemnly tells Robin at the end, "Sometimes, there are no happy endings".
** TheMovie ''WesternAnimation/BatmanMaskOfThePhantasm'' ends on quite a low note as well. After it is revealed that Andrea Beaumont is actually the Phantasm and she attempts to murder the Joker (as he was originally the hitman who killed her father), the theme park they are in is blown up and both Andrea and the Joker vanish in a cloud of smoke. Batman is left tending his wounds in the Batcave until he finds Andrea's locket, which she had left for him in the cave. The second-last shot of the movie is of Andrea standing on a cruise liner, alone. At the same time, Bruce Wayne accepts that he will always be alone and never have a normal life, accepting that he will always be Batman.
** You expect a DownerEnding from "Mad Love", but it's still harsh seeing Harley easily forgive the Joker again after [[DomesticAbuse he nearly kills her]].
** Come to think of it, EVERY episode of ''WesternAnimation/BatmanTheAnimatedSeries'' ends on a sad note in the earlier seasons and quite a few in later ones. Some prime examples include "Tyger Tyger", "Baby Doll" (and its sequel episode, "Love Is A Croc"), and the series' final episode, "Judgement Day".
** The episode "His Silicon Soul", which was a follow-up to a previous episode "Heart of Steel". A sentient computer called H.A.R.D.A.C. created robots to act as replicants to better help his creator's lab (by money i.e. robbery, etc.) before eventually taking over the city and then the world. When Batman shows up, a replicant of Batman is made in secret, but was hidden before it could be activated. Months later, it is activated by chance and unlike its predecessors was sentient in that it thought it was the real Bruce/Batman, but couldn't deal when he found out he was a robot. During the fight, the real Batman looks like he died (for a while) and the robot is so utterly horrified by this (remember it is based on '''[[ThouShaltNotKill Batman]]'''), it then goes and ''kills itself''.
** "Heart of Ice", which is considered to be the series' best episode. It won an Emmy for Outstanding Writing in an Animated Program AND made people feel sorry for Mr. Freeze!
---> '''Mr. Freeze:''' I have failed you. I wish there was another way I could say it. I cannot... I can only beg your forgiveness, and hope that you can hear me somehow... someplace... where a warm hand waits for mine...
* ''WesternAnimation/BatmanBeyond'' in general could be considered depressing when looking at Bruce Wayne's character. “Rebirth” was the first blow where it appears that he ultimately loses in his personal battle against crime. Alfred's dead. Most of his sidekicks had left him on bad terms. Not even his RoguesGallery is around. He just lives alone with a dog and a bunch of old memories. Possibly worst of all, he DidNotGetTheGirl even though he was a ChickMagnet in his youth.
** Any ''WesternAnimation/BatmanTheAnimatedSeries'' episode involving Mr. Freeze is going to be tragic, but his apparent ending in ''WesternAnimation/BatmanBeyond'' involves him finally gaining a human body and a girlfriend, both of which betray him in the end. He takes out a high-tech exosuit, is foiled by Batman, joins forces with Batman when ''BigBad'' Derek Powers/Blight goes berserk, and sacrifices himself to save the new Batman. His last words are uttered in a completely heart wrenching, fatalistic manner, to boot:
---> '''Batman (Terry):''' You've got to get out of here, Freeze! The whole place is gonna go!
---> '''Freeze:''' Believe me... you're the only one who cares.
** Other ignominious ends: Bane is comatose, wheelchair-bound, and permanently hooked up to the Venom drug just to keep his body functioning; original Batman and Batgirl had an affair that ended badly; Kairi Tanaga, the karate teacher's apprentice from ''Batman: TAS'' is killed by snake-worshipping cultists; and ''Return of the Joker'' with the aforementioned new Robin, the Joker, and the Kill Sat.
*** That last one, at least, ends on a positive note for everyone…except the Joker, of course. Bruce finally gets around to repairing his relationship with the new Robin, Terry faces the future with pride and determination, and [[spoiler:Harley Quinn is shown to have turned over a new leaf, and is now living as a law-abiding old lady.]]
** The ''WesternAnimation/BatmanBeyond'' episode "Heroes" also ended on a low note. The [[NoCelebritiesWereHarmed Terrific]] [[Franchise/FantasticFour Trio]] are betrayed by the law enforcement forces, discover that there is no cure for their powers (and their conditions are actually getting worse), and that their co-worker (who more than likely may be Doctor Doom's analogue) knew all along what would happen and that he set the whole thing up to get the Ben Grimm/Johnny Storm analogue out of the way in order to have the Sue Storm analogue all to himself. All three of the trio members are implied to die horrible deaths and only the co-worker is confirmed to be left alive, with great remorse on his part. This is shown in the exchange between Terry and the co-worker:
--->'''Terry:''' Satisfied?
--->'''Co-worker:''' No, you don't understand, I was their friend...
--->'''Terry:''' ''Right...''
** It's made even worse when you realized [[WhatTheHellHero Terry's the one who killed them]].
** This was averted in the ''WesternAnimation/BatmanBeyond'' episode "Eggbaby". A series that was originally dark to begin with, they specifically wrote a more lighthearted episode around the common theme of the parenthood high school project so that they could submit it for an Emmy. They knew this was the only way they had a chance since [[AnimationAgeGhetto animation is for kids]].
* In ''WesternAnimation/SupermanTheAnimatedSeries'', pretty much any episode with Darkseid was liable to end on one of these notes. In "Apokolips Now!", Darkseid's initial invasion of Earth is foiled, but he shockingly kills Creator/JackKirby {{Expy}} Dan Turpin before leaving. Worse, the major pwning that Darkseid delivered to Superman implies that the Man of Steel will be powerless to stop him next time. In the series finale "Legacy", Darkseid brainwashes Superman into conquering Earth for him, destroying his reputation with the entire human race. When Supes finally defeats Darkseid in battle, Darkseid is rescued by ''his own slaves'', who worship him as a god, leading us to conclude that real victory over Darkseid is impossible (at least until ''WesternAnimation/JusticeLeague'').
* Speaking of ''WesternAnimation/JusticeLeague'', The episode “Kid's Stuff” was a hilarious, light-hearted romp... until THIS exchange:
--> '''Wonder Woman:''' "Circumstances aside, it was kind of enjoyable to be a kid again."
--> '''Batman:''' "I haven't been a ''kid'' since I was eight years old..." (he walks off with everyone looking uncomfortable and then following silently)
* ''WesternAnimation/BatmanUnderTheRedHood'' ends on an almost nihilistic note. Batman has been betrayed by Jason Todd, the Robin he believed dead, and had it rubbed in his face that his war on crime is unwinnable, that the Joker will keep escaping his cardboard prison to kill and maim until the day he dies, and that untouchable crime lords will continually hold Gotham in their grip. Any promise of a brighter tomorrow will be destroyed by the scourge of time.
* Despite its reputation as being more child-friendly than its predecessors, ''WesternAnimation/TheBatman'' has a few:
** ''Meltdown'' ends on a very crushing note. Not only does Ethan "Clayface" Bennett get sent back to prison, efforts at readjusting to society a total failure, but he sees his old partner in the police, Detective Ellen Yin, ''replace'' him with Batman. While most supervillain rehabilitation efforts fail [[SuperheroParadox for obvious reasons]], most end with at least a shred of optimism (or otherwise feature villains who never really made an effort). But not this one.
** ''A Fistful of Felt'' ends with Arnold Wesker's rehabilitation being sabotaged by his psychiatrist [[PsychoPsychologist Hugo Strange]] ForScience. He gets sent back to prison while Strange gets nothing more than a warning from Batman, which he no doubt forgets by the time he turns back to the paddy-wagons.
** ''Seconds'' revolves around time-controlling villain Francis Gray who is attempting to gas Gotham's New Year's Eve party (where millions will be in a small area) for throwing him in prison [[DisproportionateRetribution for 17 years for a minor crime]]. Batman realizes he can't stop him since he can just rewind all of his mistakes, so he sends Batgirl to get his son to try and talk him down. Except she's late, so not only does Gray successfully kill millions but he watches his son die in front of him. It gets [[CosmicRetcon cosmic retconned]], but still.
* ''WesternAnimation/MyAdventuresWithSuperman'' episode "[[Recap/MyAdventuresWithSupermanS1E04YouWillBelieveAManCanLie You Will Believe a Man Can Lie]]" ends as Lois and Clark have an argument over Clark keeping his Superman identity a secret from Lois despite her hatred of being lied to, and when their argument reaches a boiling point, Lois declares that whatever they had is over, leaving Clark sad as a result, while Jimmy not only has his troll denier, who turns out to be Steve, get away from his trolling to him scot-free but he also gets kidnapped by a gorilla in the woods.
* The ''WesternAnimation/TeenTitans2003'' animated series ended with "Things Change", an episode that saw long-lost ex-Titan Terra, who had previously become a stone statue at the end of her story arc, alive and living a life of mundanity. The stage seems set for a joyful reunion, but after repeated claims that she doesn't know him, "The Schoolgirl" admits that "Things were never the way you remember," and rejects Beast Boy's pleas to get her to return to the team. The team never did defeat the monster they had been fighting the whole episode either.
* ''WesternAnimation/YoungJustice2010'' has quite a few:
** "Failsafe" ends with Miss Martian sobbing uncontrollably and the team left shaken after a training exercise goes horribly wrong. We're also left with the unsettling implication that Miss Martian may not be able to control her immense mental abilities.
** The final sequence of "Misplaced" juxtaposes a shot of Zatanna sobbing over the loss of her father with another of Klarion laughing maniacally as he and his fellow villains move one step closer to completing their master plan.
** The ending of "Insecurity" sees Artemis berated by her teammates for being immature and selfish, only to then be offered a chance to betray the team by her father.

* ''WesternAnimation/MyAdventuresWithSuperman'' episode "[[Recap/MyAdventuresWithSupermanS1E04YouWillBelieveAManCanLie You Will Believe a Man Can Lie]]" ends as Lois and Clark have an argument over Clark keeping his Superman identity a secret from Lois despite her hatred of being lied too. When their argument reaches a Boling point, Lois declares that whatever they had is over, leaving Clark sad as a result. In contrast, Jimmy not only has his troll denier, who turns out to be Scott, get away from his trolling to him Scott free, but he also gets kidnapped by a gorilla in the woods.

* ''WesternAnimation/PerfectHairForever'': Gerald seems to go insane with trying to get Brenda from Young Man. After Sherman eats the Hamburger Necklace that could have possibly worked somehow, he resorts to assassinating him. The result isn't shown, but at some point after that, Coiffio's box army comes back into play and overruns the Tunaminium. In short, Young Man loses his life, Brenda loses her fiance, and Gerald loses his mind and doesn't get his perfect hair.

* ''WesternAnimation/Animaniacs2020'' ends with the Warners acknowledging that with no word of another season, [[EndOfSeriesAwareness there is a good chance their renewed show has come to an end]]. [[ShootTheShaggyDog The fact that a giant meteor is about to pretty much kill everyone does not help matters at al.]]

* Thanks to it being unexpectedly canceled, the ''WesternAnimation/SilverSurfer'' series ends with the Silver Surfer apparently dead and the universe destroyed.

* ''WesternAnimation/TheFairlyOddParents'' - "Secret Origin of Denzel Crocker": Not quite a YouCantFightFate as it would've happened without him going back in time, but Timmy goes back in time to try to stop his teacher from becoming madly obsessed with fairy godparents; he successfully stops it from happening the way it did originally (it was apparently Cosmo's fault), but then, thanks to Cosmo, ends up making it happen anyway.

** "Squid On Strike" ends with [=SpongeBob=] and Squidward's skeletons still working at a dilapidated Krusty Krab when, centuries ago, after [=SpongeBob=] actually destroyed the building because Squidward filled his head with the idea of a strike and Mr. Krabs made them work ''[[NotHyperbole forever]]'' to pay for the damages.

** In episode 24 of season 4, Nabu dies after using up all of his energy to close the shadow abyss, and the power that could've revived him is stolen by Ogron, who wastes it on a flower. Layla ends up leaving the Winx to join the fairy Nebula's army in order to avenge Nabu's death, despite her friends trying to tell her that that is not what Nabu would've wanted.

** "Dexter Detention" has Dexter succeeding in breaking out of [[DetentionEpisode detention]]... but then he's last seen breaking rocks at gunpoint after accidentally [[OutOfTheFryingPan breaking into a prison]].

** "The Old Switcharooms" has Dee Dee and Dexter [[YouAreGrounded being sent to]] ''[[GoToYourRoom each other's]]'' [[GoToYourRoom rooms]] as punishment for bumping into their father during an argument and making him drop his bowling trophy, causing it to break. Dexter knows [[LethallyStupid Dee Dee]] [[WhatDoesThisButtonDo will try to enter his lab and destroy it like she always does]], and in making a stealth suit to investigate unnoticed after previously trying to walk out the door, [[PayEvilUntoEvil he destroys her bedroom in the process]]. [[spoiler:He later finds out she was asleep the whole time]]. When the grounding is over and Dad had finished fixing his trophy, he and Dee Dee find the damage Dexter did to her bedroom, at which point Dexter is banished to the doghouse. Dexter doesn't seem to worry about the dog entering his lab and destroying it, but he was wrong!

** Season 3 somehow manages to one-up the bleak ending of the first season. [[spoiler:Ash betrays the Team Squad and frees Invictus from its prison; Gary loses Mooncake, whose [[UncertainDoom final fate is unknown]][[note]]albeit, series creator Creator/OlanRogers [[WordOfGod later confirmed that he survived]][[/note]]; AVA, Fox, Clarence, Kevin Van Newton, and Bolo are all KilledOffForReal; and Earth is destroyed for good. The finale ends with the surviving heroes watching in horror and defeat as Invictus escapes from Final Space in its true form, now free to conquer every timeline. And worst of all, since the show was officially cancelled [[ScrewedByTheNetwork due to external corporate factors,]] this is the ''very last'' we're seeing of these characters.]]

** The episode "Twisted Sister" has a horrible Downer Ending. The girls create a new sister named Bunny. Despite her infantile mind and hulking, Quasimodo-like physique, she learns to be a hero, saves the day, and then just randomly... explodes, probably due to them missing ingredients when they made her. [[OOCIsSeriousBusiness Even]] ''[[OOCIsSeriousBusiness the narrator]]'' [[ManlyTears is in tears]] as the episode ends, complete with [[DarkReprise the background music for the end shot playing in a very melancholy tone]]. What a MindScrew for any kid watching it. Some odd parallels between ''Literature/OfMiceAndMen'' can be found here as well. And of course, that's the episode that finally won the show a [[OscarBait damn Emmy.]]

[[OOCIsSeriousBusiness Even]] ''[[OOCIsSeriousBusiness the narrator]]'' [[OOCIsSeriousBusiness is in tears]] as the episode ends. What a MindScrew for any kid watching it. Some odd parallels between ''Literature/OfMiceAndMen'' can be found here as well. And of course, that's the episode that finally won the show a [[OscarBait damn Emmy.]]
