Downer Ending/Western Animation

"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..."
 * In The Simpsons, the first two episodes where Mother Simpson comes back have melancholy endings. In the first, Homer sits for hours on his car after Mona is forced to go away again. In the second, she's alive but he doesn't know it. Even when he tells himself she's alive (after finding a 'message' that says 'I'm OK'), none of them show any signs of believing in it and the real message is a sweet down-to-earth one that they don't find. The third of these episodes has Mona Killed Off for Real, but it nonetheless ends on a more upbeat note.
 * Pick any Treehouse of Horror segment. Nine times out of ten, it'll have this kind of ending. Played for Laughs, of course.
 * Subverted in the episode "One Fish, Two Fish, Blowfish, Blue Fish", when it appears Homer has died in an armchair in the living room. In the end, Marge discovers Homer is still alive and he promises to live life to the fullest. The episode ends on a downer ending as it shows Homer wasting his life eating pork rinds and watching TV, as usual.
 * The episode with Herb. Homer designs a car which nobody likes, yet it cost a fortune to make, and ends up putting Herb out of business.
 * This is why they made an originally-unplanned sequel episode, where Herb gets rich again and forgives his brother in the end (and Homer gets a nice new chair).
 * WITCH is more or less composed of nothing but downer endings, except for the season finales. The villain always tends to be one step ahead of the heroes and with each step closer to achieving their plans, all the heroes tend to get is motivation to do better next time... and they're luck to even achieve that! The heroes are on the losing side of the war for just about every episode.
 * Avatar: The Last Airbender ends its second season with The Hero being struck down during his Transformation Sequence, leaving him horribly wounded and believed dead; the heroes barely escape as the Earth Kingdom falls to the Fire Nation, which now rules the world almost uncontested; Prince Zuko has regained his place in the royal family as he tried to all along but at the cost of betraying his beloved uncle, and is left wondering if it was worth it.
 * Several other Avatar episodes end in Downer Endings; the most important of these is "The Day of Black Sun Part 2: The Eclipse", where most of the invasion force is captured, and Aang must retreat with only a few allies. The only thing that came out of it was Zuko's Heel Face Turn, but to them it seemed like a full Shaggy Dog Story.
 * Before that there was "The Puppet Master", which ended with Hama succeeds in forcing Katara to use the technique she swore she'd never use.
 * And most recently, the play of their adventures in "The Ember Island Players" ended in Aang's death and the Firelord's victory. Justified because it was shown in the Fire Nation, where that was the ending everyone pretty much wanted - and the only one the government approved, most likely.
 * Most likely??? The government declared A God Am I the very next episode!
 * And mention has to be made of "Appa's Lost Days"; Appa endures all kinds of hardship, survives and makes it all the way to Ba Sing Se where Aang is, and just as the audience is gearing up for the happy ending... he's captured again and dragged down into the earth, leaving only a single footprint to show he was ever there.
 * "Zuko Alone". Zuko offers to help out a small farm family by rebuilding their barn and protecting them from corrupt, dishonorable soldiers. He teaches the little boy to wield a sword and never give up without a fight. Meanwhile, Zuko remembers how back at home the only person who cared for him was Ursa. It seems almost as if Zuko will find some acceptance in his new life as a refugee. But when his fight with the soldiers reveals who he is, he gets run out of town by everyone for being the Fire Nation prince. Poor Zuko.
 * "City of Walls and Secrets" also qualifies as this with Jet being arrested and brainwashed, Joo-Dee being replace and the revelation of Ba Sing Se really being a dystopic and corrupt city where the Earth King is merely a puppet.
 * Batman: The Animated Series had a couple of these. Such as 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, 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, Not Quite Dead). The episode ends on a wide shot of the cliff, Batman climbing up and helping Stella who is now in tears. The tragedy of it all is somewhat dampened by the fact that this is a Shout-Out episode: Dr. STEELLLAAAAAA!!! hid her Frankenstein's lab in the Bates Motel, while Clayface himself resembles an Oscar statue.
 * In the sequel to that episode, 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 trying to figure out just what to charge Clayface with, Robin bitterly says "Murder."
 * Batman even solemnly tells Robin at the end, "Sometimes, there are no happy endings."
 * The Movie Batman: Mask of the Phantasm 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.
 * Come to think of it, pretty much EVERY episode of Batman: The Animated Series 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 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 Batman), it then goes and kills itself.
 * Let's not forget "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!

"Batman (Terry): You've got to get out of here Freeze! The whole place is coming down! Freeze: Believe me... you're the only one who cares."
 * Batman Beyond 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 Rogues Gallery is around. He just lives alone with a dog and a bunch of old memories.
 * Pretty much any Batman: The Animated Series episode involving Mr. Freeze is going to be tragic, but his apparent ending in Batman Beyond 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 Big Bad 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:

"Terry: Satisfied? Co-worker: No, you don't understand, I was their friend... Terry: Right..."
 * Other ignominious ends: Bane is permanently hooked up to the Venom drug just to keep his body functioning; original Batman and Batgirl had an affair that ended badly; the Movie with the aforementioned new Robin, the Joker, and the Kill Sat; the karate teacher's apprentice from BTAS is killed by snake-worshipping cultists.
 * The Batman Beyond episode "Heroes" also ended on a low note. The Terrific 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 3 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:

"Fifi: "This ending stinks!""
 * It's made even worse when you realized Terry's the one who killed them.
 * This was averted in the Batman Beyond 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 animation is for kids.
 * Batman: Under the Red Hood 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.
 * Tiny Toon Adventures has probably one of the most infamous examples, especially towards Fifi LaFume fans. In the short "Out of Odor", Elmyra has her mind set on having Fifi as her pet, but first has to get rid of her stink. After a mean use of trickery and a brief chase, Elmyra finally captures poor Fifi.
 * This one was lampshaded by Fifi herself.

"Buster: "So, do we get to do a funny episode tomorrow?""
 * There is, however, a popular fan theory that "Out of Odor" might be a prequel to the episode "Hare Today, Gone Tomorrow", which also shows Fifi as one of Elmyra's pets and she is rescued by Buster.
 * "Out of Odor" is referenced in How I Spent My Vacation when Fifi kicks Johnny out of the theater and he lands in Elmyra's arms, where she then mistakes him for a cat, calling him "stinky kitty" like she did with Fifi in Out of Odor and skips into background while slamming Johnny into the ground like she did with Fifi in the ending of Out of Odor.
 * "One Beer" ends with Buster, Plucky, and Hamton driving off a cliff and getting killed as their car crashes into a graveyard. This is lampshaded by Buster at the end of the episode.

"Cartman: And they all lived happily ever after... except for Kyle, who died of AIDS 2 weeks later. Kyle: Goddamnit, Cartman!"
 * The episode actually got pulled from syndication because of it!
 * The Teen Titans 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.
 * At the end of the "Total Drama Island" season 3 finale, Heather throws a pineapple into the volcano, causing it to erupt and kill almost everyone in a huge meteor shower. At the end, Heather is impaled by a giant rock.
 * It's not clear if that really happened, is it?
 * In Superman the Animated Series, 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 Jack Kirby 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 'Western Animation/'Justice League'').
 * Transformers Beast Wars ended in a bittersweet finale. Though the Maximals had defeated and captured Megatron, they suffered heavy casualties as well. The first Dinobot sacrificed himself earlier on to prevent Megatron from destroying the proto-humans. Depth Charge killed himself and Rampage in a final attempt to stop Megatron from raising the Nemesis (he didn't succeed, though he did get closure with his long-time nemesis Rampage). Tigatron and Airazor came back as one being, Tigerhawk, only to be gunned down by Megatron aboard the Nemesis in a last-ditch effort to stall Megatron. The Transmetal II Dinobot finally turned good only to die just a few seconds later after refusing to save himself from the exploding warship. Heroes aside, fans have also expressed sadness with the deaths of the Predacons as well, including Rampage, Inferno, and Tarantulas. If we're counting Transmutate, both Dinobots as separate characters, and Tigatron, Airazor, and Tigerhawk as separate as well, then Beast Wars ended with a death toll of 14 characters out of 22. That's more than half the entire cast.
 * The opening to Beast Machines makes this an even bigger downer ending. Not only did it turn out that they lost the beast wars, they inadvertently gave Megatron the power to conquer all of cybertron, and enacting a genocide that would make the holocaust look like a drive-by murder. Of the surviving few Maximals left, two of them were kidnapped and transformed into Megatron's new generals, while the rest were robbed of their transformations and memories.
 * Beast Wars had numerous episodes end with the bad guys having victories, or simply leaving everyone down and out.
 * The episode Transmutate had the eponymous character die trying to stop its friends from killing each other, with both Silverbolt and Rampage mourning its death.
 * The episode "The Probe", a Maximal probe travels to Earth. The Maximals try to get a signal to it, but Megatron destroys their tower, denying them their chance to get home.
 * In the classic Transformers episode, "The Golden Lagoon", Beachcomber discovers a quiet, peaceful, Bambi-esque clearing filled with wildlife. A closer look reveals a lake of liquid "electrum," a gold and silver compound with the oddly useful effect of making Transformers apparantly invulnerable. He attempts to keep it to himself but the Decepticons find it anyway and proceed to let all hell break loose. Eventually the Autobots win out but it doesn't happen without the place being gutted by the ensuing chaos. At the end, all Beachcomber can do is look dejected at the ruined landscape and utter "Yeah... we won."
 * Hey Arnold! had a few:
 * "Arnold Betrays Iggy": ends with Arnold mad at Iggy for forcing him to wear bunny pajamas.
 * "Helga and the Nanny": ends with Helga's homelife back to its regular dysfunctional state.
 * "The Pigeon Man": That whole episode's a Downer, but at the end, Pigeon Man loses his home thanks to the bullies who don't understand him, after he's lived as a hermit for years to avoid people like them. But the clincher is that all of his pigeons each grab a string attached to Pigeon Man and fly him away into the sunset. Make what you want of the metaphor. There is a small bit of hope since Arnold's kindness convinces the Pigeon Man that not all people are jerks who will treat him like an outcast, but it's still a pretty depressing episode from start to finish.
 * Futurama: many of its Emmy-nominated episodes, plus:
 * "Time Keeps on Slipping": Fry forced to blow up the star pattern he had meticulously created for Leela, which would apparently have been enough of a romantic gesture for Leela to finally return his affections if she had seen it. She coincidentally didn't see it because she was trying to cheer up Fry.
 * Also in that episode, Bender's dream is to become a Harlem Globetrotter. He fails to achieve this goal even though the rest of the crew are declared honorary Globetrotters just because they were in the right place at the right time. During the end credits, we hear Bender sadly whistling the Harlem Globetrotters' theme song.
 * "Jurassic Bark": Fry decides at the last minute not to resurrect his fossilized dog, reasoning that it had lived a full and happy life and Tampering In God's Domain was not wise. A final montage reveals that, in fact, the dog had spent the rest of its life pining for its lost master. The Retcon in the first movie attempts to cancel this out, but we all saw what really happened.
 * In "Bender's Big Score" Fry goes back in time, meaning that his dog did manage to be with him. And what's more, on 2012 (the year when he was supposed to die) Bender tracks down Fry, who is living in his old Pizzeria. He fires a laser at the building and it collapses and Fry's dog looks at it just in time for the fire and dust to instantly fossilize him. This was a bit of a Retcon, due to most fans finding the original ending soul crushingly depressing.
 * There was also the episode where Fry was influenced by worms to be much more intelligent and much stronger, when he blew into a hologram-creating instrument that apparently takes massive amounts of effort to play correctly and performs an elaborate and romantic image for Leela. After he decides that he'll get rid of the worms to see if it's really him or the worms that Leela had started taking to during the episode, he tries to play it again, only being able to create the image of the Frankenstein monster roaring. After Leela leaves, he sits alone, realizing that he's come up short in his romantic pursuit again.
 * Rocket Power - "Power Play": In the final seconds of a roller hockey game where the winner gets to play NHL stars, Twister's game tying shot at the end is disallowed.
 * "The Big Air Dare" ends with Otto breaking his leg during a snowboarding match with Reggie on a forbidden slope, the kids sans Otto being forced to shovel snow as punishment (which Reggie herself says it's cruel), and their faces plastered on the "Wall of Shame". Luckily, "Otto's Big Break" is part 2 of the episodes shown, and it ends with a happy ending despite Otto's leg still being broken.
 * Also, the ending of the kayaking episode where the kids were forced to clean up the Shore Shack for a month as punishment.
 * Two episodes that air together regularly, "Shark Bait" and "A Shot in the Park".
 * The Fairly Odd Parents - "Secret Origin of Denzel Crocker": Not quite a You Can't Fight Fate 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 accidentally ends up making it happen anyway.
 * As Told by Ginger: "Hello Stranger": a subversion of the Visit by Divorced Dad trope.
 * And in "No Hope for Courtney", Ms. Gordon dies and Carl starts to cry at the news of this. Originally, Ms. Gordon was going to come out of retirement, but the voice actor died during production so it was rewritten that her character died as well. Since Ms. Gordon died and also her actor, you might say it's a The Character Died with Him.
 * In the end of the opera-themed Looney Tunes cartoon "What's Opera, Doc," Elmer Fudd has "killed the wabbit," and the dead Bugs Bunny gets up so he can do a bit of Lampshade Hanging: "What did you expect in an opera, a happy ending?" It's true: most famous operas have Downer Endings.
 * Averted In the Walter Lantz cartoon Flying Turtle herman the turtle wants to learn how to fly, so he gets an eagle to take him up almost to the edge of outer space, when he finally tries to fly he falls all the way to Earth, and dies in the process,
 * The Powerpuff Girls, 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. Even the narrator is in tears as the episode ends. What a Mind Screw for any kid watching it.
 * Some odd parallels between Of Mice and Men can be found here.
 * And of course, that's the episode that finally won the show a damn Emmy.
 * Of course, they neither had sugar nor spice in the process.
 * The end of the Fantasia segment, "Rite of Spring", could be seen as a downer ending, since all the dinosaurs die. As a matter of fact, if it weren't for the Executive Meddling, Walt Disney would have kept the happier ending where a band of early humans start a bonfire and then dance in celebration of their discovery.
 * The last episode of Home Movies ends with Brendan accidentally dropping his beloved video camera out of the window of a car and watching it get run over and smashed by another car, after he had given up on his dream of being a film maker because he believed that his movies shouldn't be watched, despite producing impressive material for an 8-year old with a cheap camcorder.
 * Those of us who didn't think it was protected by the Rule of Funny thought the ending to Camp Lazlo fell under this: it looks like something's gone right for Lumpus, when it turns out he's just some looney who has the real Scoutmaster, an aged version of Heffer from Rocko's Modern Life, locked up in a closet and is dragged off to a looney bin. A person actually complained to the creator that it was a low note for a finale, so he told her that Jane bailed Lumpus out and they lived Happily Ever After in Acorn Flats... but still...
 * Thanks to it being unexpectedly cancelled, the Silver Surfer series ends with the Silver Surfer apparently dead and the universe destroyed.
 * In later seasons, South Park has grown to love this trope. Here are some examples:
 * The episode where Stan is forced to coach a Pee Wee Hockey team is considered one of the most miserable. One of the kids on the team has Leukemia and promised that he would live if they won a game. Eventually, they are asked to play a game at Pepsi Stadium against another Pee-Wee hockey team, but when the opposing team doesn't show up, the Colorado Avalanche volunteers them to play against the Detroit Red Wings. In probably the most cruel subversion of feel-good sports movies, if not anything ever, the Detroit Red Wings crush the poor kindergarten team by 31 to 1, all while brutally hurting many children who are less than 6 years old. When the Wings win, they have their own cliche "victory scene" while Stan's poor team is left writhing on the floor and quite a few people feeling resentment towards Stan for failing them so badly. The last shot in the episode? The child with Leukemia utters "...no hope..." and friggin dies. Okay, so winning a hockey game won't save a kid's life, but MAN was that the saddest death EVER. Made even worse by the Mood Whiplash of South Park's closing credits song.
 * How about the one where Britney Spears dies? It sounds funny, sure, but MAN. That was a dark episode.
 * "Kenny Dies": The kids spend the whole episode trying to get stem cell research allowed so they can save Kenny's life. In the end though, Kenny dies anyway, just too late. To make matters worse, Stan avoided Kenny the entire episode because he couldn't handle the idea of his friend dying. In the end he finally decides to tell Kenny he cares, and there's even a dramatic scene with him running to the hospital with balloons and a present - only for him to find out that Kenny had already passed on. Of course, this being, well, Kenny, he got better, but that doesn't make this episode any less depressing, especially when Word of God states that they'd originally intended for Kenny to be Killed Off for Real.
 * Parodied in "Woodland Critter Christmas" as a happy ending:

""And they all lived happily ever after... except for Pocket, who died of Hepatitis B.""
 * Their version of Great Expectations had a very similar parody, predating the Woodland Critter Christmas episode:


 * "Toilet Paper" had a really brutal downer ending: Kyle, riddled with guilt over the fact that he and his friends T.P.'d their art teacher's house out of resentment, was going to apologize, but unfortunately, Cartman beat him, Stan, and Kenny to the punch. Stan, Kyle, and Kenny are sentenced to 2 weeks detention, while Cartman only gets 1 for being 'honest'.
 * "Raisins". Oh God, "Raisins". Wendy breaks up with Stan, sending him into a Heroic BSOD that leads to him becoming a goth. Kyle showed a Lack of Empathy towards his own best friend over the break-up, and Stan sees Wendy with Token, the rich black kid, breaking Stan even more inside. In the end, after a pep talk from a similarly heartbroken Butters, Stan rejects Wendy. It took 4 grueling years for Stan and Wendy to be a couple again.
 * The 9th season premiere. Although, it is more of a Bittersweet Ending for Garrison, and Garrison only.
 * "Lice Capades" had a downer ending for both the lice and the kids. ALL of the kids were revealed to have lice, including the girls, and the louse hero lost his loved ones.
 * The louse hero does manage to save his baby and find refuge in a new home where, it's implied, they can live happily without fear, so this one might be upgraded to Bittersweet Ending on that front.
 * "You're Getting Old"  All of this happens while sad music plays.
 * My Life as a Teenage Robot, of all places, for an animated sci-fi/comedy has a really overly-dramatic Downer Ending in "Mist Opportunities". Jenny meets up with her friend Misty, whose ways of fighting evil aren't what Jenny cottons to. In the end, Jenny and Misty fight, and Misty beats the ever-loving crap out of Jenny, and apparently defeating her. And rather than finishing off the robot girl, Misty gives her a "reason you suck speech" and leaves her, scrapped in a partially-destroyed Tremorton.
 * The Lilo and Stitch The Series episode, Angel. Stitch falls in love with an experiment (who basically looks like a pink female version of Stitch), but Lilo has suspiscion towards her because her siren-like song reverts any of the experiments that have been converted for good back to their destructive states. Luckily, Stitch and 625 were immune because they were made after Angel. In the end, Stitch makes Angel see the error of her ways, but sadly, she was captured by Gantu. However, this was due to the executives disliking the idea of Angel, much to the dismay and anger of the fans. It gets fixed in the series finale, Snafu.
 * Ed, Edd n Eddy often ends with either the Eds humiliated or raped by the Kanker Sisters, and they're often funny endings, since it is a funny show. But only ONE ending actually qualifies for a Downer Ending: the ending to If It Smells Like An Ed. The Eds were accused of ruining Friendship Day, and tried to clear their names. Unfortunately, Act II has the Eds accused of bounding and gagging Jonny when actually, they found him this way. The kids refused to believe the Eds and chased them into the woods. The Eds hid in a shed, only to run into The Kanker Sisters. The cowardly three are then trapped between the kids, who are practically wishing for the Eds to die, and the Kankers, who demand the Eds to make out with them. The Eds prefered to have fruit pelted at them by the kids. It was then revealed that Jimmy, of all people, set them up. His motive? The wedgie (and subsequent humiliation) given to him earlier that day by Eddy. He then has the Kankers take the Eds away.
 * The episode "Take This Ed and Shove It" also qualifies in a way -- Eddy had just woken up from the Rip Van Winkle and declares, "I don't ever wanna grow up!" Cue Eddy waking up again, back as an old man. He soon realises that he fell asleep reminiscing about his childhood with his friends. The episode ends with him wishing he was still a kid. And this was the original series finale.
 * The British animated film The Plague Dogs is depressing throughout, with the story being based around two dogs who escape from an animal testing lab and try to survive in the Lake District. However, even by the standards of the rest of the film, the ending can still be considered a downer. The film ends with the two dogs being hunted by the Army, who believe that they are carrying the bubonic plague. The dogs are cornered at the beach, and try to swim to an island that doesn't really exist. It is implied that they drown.
 * The book's ending is quite nice, though. Read it, it'll cheer you up.
 * It's been suggested that the "island" in question actually is death. Because really, life's been so painfully cruel to Rowf and Snitter that death could only be a blessing.
 * Superjail, of all the shows, had a downer ending in episode Mr. Grumpy-Pants where a little girl with cancer ends up in Superjail.
 * Moral Orel had quite a few episodes end on a low note, but managed to actually subvert this trope for the Grand Finale. Clay completely ruins his marriage and his affair with the coach, and his life is left in shambles, and even with Orel's upbeat happiness, he hates Clay. While Clay is a Jerkass, it's implied that Orel's life is pretty messed up too as his idealism is shattered. However, the subversion is that fast forward many years, and Orel grows up to raise a functional family.
 * In the Family Guy episode "The Cleveland-Loretta Quagmire" Loretta has an affair with Quagmire. The episode ends with the couple getting into an argument and deciding to divorce.
 * Even sadder is the fact that Cleveland Jr. has been negatively affected by the split.
 * And even more sadder episode is "Movin Out", in which Brian breaks up with his girlfriend Jillian, being probably the saddest moment in the show's history. They tried to soften this during the credits, to little effect.
 * "Brian Wallows and Peter's Swallows" has Brian saves a woman from committing suicide, and convinces her to go outside for the first time in years. She immediately gets hit by a car, and dies (and lives long enough for Brian to take her around the world in a virtual reality).
 * The final two parter of the short lived series Clone High is probably the most upsetting use of a downer ending as the entire main cast with the exception of Principal Scudworth are frozen in a meat locker just as Abe Lincoln realizes his feelings for Joan of Arc only to discover she has just slept with J.F.K. the show ends with a To Be Continued... The cancellation of this show is scientific proof that MTV blows.
 * The ending of Foofle's Train Ride (1959) could be seen as a downer.
 * The series Delta State ends on a definitive low note. After the heroes manage to recover their lost memories, vanquish the Big Bad once and for all and avert the apocalypse, Luna, who has the power of precognition, sees an alternate ending to a vision of the future she had repeatedly over the course of the series: in the original ending, the world is destroyed; in her new vision, she foresees that her and her friends will eventually be possessed by rifters, the bad guys.
 * SpongeBob SquarePants has sevral Downer Endings that are undone by negative continuity and Played for Laughs, but there are some more tragic endings. Plankton's Regular has  and Cephalopod Lodge has.
 * Another episode "Good Neighbors" ends with.
 * The saddest downer ending in the series is "One Coarse Meal"..
 * Young Justice 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 abilites.
 * 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.
 * Ace Lightning had a fair few downer ending episodes. One where Sparx was killed by a couple of crazy puppets shooting her with her own sword (which came completely out of the blue in what had previously been a fairly light hearted episode), another in which the protagonist's ex-girlfriend all but ended up hating him through no fault of his own (actually there are a few of those), and then of course there's the final episode where at least one major bad guy gets away, Lady Illusion is shot dead and the other bad guy is shown to be well and truly alive in the Sixth Dimension -and holding the Master Programmer hostage. We never found out what happened due to the cancellation.
 * The second half of the first Season of Winx Club gets many of these too. Let's see: Mirta, the first (and only) friendly witch (who's also half-fairy) gets turned into a pumpkin when she was trying to help Bloom, speaking of which, she later finds that her boyfriend is a prince and is in an arranged marriage with another girl. After finding this, depressed, she returns to Earth, where the Trix steal her powers, becoming much more powerful. With her new powers, the Trix then proceed to take over Cloudtower, summon an infernal army to conquer the world. However, things got better for every good character.
 * Episode 8 has Darcy successfully seducing Riven and walking away without any punishment. Stella outright says "We lost this one."
 * Also, a Season 3 episode ends with Tecna apparently sacrificing herself to save Layla's homeworld. However, she wasn't really dead.
 * 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.
 * The Gargoyles: The Goliath Chronicles episode "Genesis Undone": With the clones suffering from a genetic defect that will cause them to become stone permanently, they and the Manhattan Clan reluctantly seek the aid of Dr. Sevarius. However, Sevarius uses the Manhattan Clan's DNA not to save the clones, but to give life to his own new, improved clone, whom he refers to as his son. Some fighting later and Goliath turns Sevarius' 'son' to stone, leaving the doctor desperately pining for the one thing he had ever cared about. Meanwhile, the clones have already been permanently petrified, and there is apparently no way to reverse the process.
 * The episode "Metamorphosis" has Elisa's brother Derek infected with a drug that turns him into a mutant Gargoyle as part of a Dr. Sevarius experiment that supposedly not even Xanatos approved. Then Sevarius, the only one who could reverse the process, gets killed, and Derek blames Elisa and the Manhattan Clan for everything. It's then revealed that Xanatos set up everything to turn Derek into the mutant, including faking Sevarius' death. Of all the corrupt and morally questionable things Xanatos did over the series, this may be the only one that was truly EVIL. The episode ends with Elisa sobbing amongst the Manhattan Clan.
 * Season one of Titan Maximum ends with Gibbs succeeding at frying Mercury and killing billions of old people. The episode was titled "One Billion Dead Grandparents" after all. In the DVD Commentary, writer Matt Senreich actually invokes the trope - "Downer Ending right there. Downer Ending."
 * Would you believe there was an episode of Tom and Jerry 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.
 * There is another Mouseketeer episode where the final scene is Jerry and Nibbles walking down the street. There is a drum roll and the silhouette of a guillotine dropping--on Tom's head. Nibbles replies "C'est la vie."
 * Naturally current showings of these episodes always cut to the credits.
 * Not true. Everytime I see the Mouseketeer episode on Cartoon Network it has the Downer Ending intact.
 * Spider Man the Animated Series has an episode that shocked us with its combination of Downer Ending and Wham! Episode. 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 Bittersweet Ending as Spider-Man saves reality itself from being destroyed... but Mary Jane is still missing.
 * Well, it was somewhat foreshadowed in that MJ's sudden return was totally out of the blue, she didn't seem traumatized by several months in interdimensional void and therefore something wasn't right. And the end of the series strongly implied that Spider-Man will find her, with Madame Web's help and all. The plan was to shoot five more episodes which would involve him doing just that, but the show was canceled.
 * Similarly, Spider-Man Unlimited 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.
 * The Spectacular Spider-Man 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.
 * And you forgot about Harry; his 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 pretty much stole his girlfriend, which is worse as Harry feels inferior to Peter 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, Flash, Robbie and Sally.
 * How the hell has Spider-Man: The New Animated Series not been mentioned? 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 Roaring Rampage of Revenge, 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 Mind Rape 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 the 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.
 * Western Animation/Wolverine and the X-Men}} ended with Jean back, and the the Bad Future averted. However,  But hey, the producers set that up so it could all be resolved for season 2. I mean, there's no way the show will be cancelled on a cliffhanger this enormous.
 * Sonic the Hedgehog, anyone?
 * What is it with superhero shows getting cancelled??
 * Adventures of the Galaxy Rangers had a couple of Bittersweet Ending episodes that veered plenty bitter. The pilot episode "Phoenix", for one. The Hero Zachary Foxx is gunned down and paralyzed, only to be fitted with experimental cyberware, the Big Bad is loose in the galaxy and has a few dozen humans hostage after a successful attack on a League Planet. The privateer still has Zach's wife. The only good parts are that the kids escaped (though Mandell's original pilot had them captured as well), and that BETA authorized the Ranger team to strike back.
 * ReBoot loved these after getting Darker and Edgier. Web World Wars ends with Bob exiled in the web and Megabyte in position to take over. Game Over ends with Enzo losing an eye and the game resulting in everyone thinking he's dead. System Crash ends with Phong explaining that despite their hard work, Mainframe is still doomed. Then comes the cliffhanger in season 4, where Megabyte has taken over the Principal office.
 * The Phineas and Ferb episode "Candace Gets Busted" ends with... Do I really need to say it?
 * The Ben 10 Ultimate Alien episode "Revenge of the Swarm" ends with Elena killing herself to stop the Hive Queen... only to reveal that they are still active. What a Senseless Sacrifice.
 * The Danny Phantom episode "Public Enemies" ends with Walker essentially winning, having managed to turn almost the entire town of Amity Park against Danny (including Jack and Maddie now viewing him as a threat to be destroyed) and labeling him as the main cause of ghost attacks. Sure, Walker gets sucked back into the Ghost Zone at the end, but it's only because Wulf sacrificed his own new-found freedom to do so.
 * In Iron Man Armored Adventures, a HUGE one comes in "Ghost in the Machine" -  Big downers all around.
 * The Two Stupid Dogs episode "Red Strikes Back" - the duo once again encounter Red Riding Hood, she blissfully ignores her grandma's cries for help as she's yet again devoured by the wolf, and encounters the witch from Hansel and Gretel who notices her and the dogs munching on her house; she takes Red inside and forces her to eat a ton of food. Once she grows wise to the witch's plan to eat her, she kicks her and attempts to escape, but the witch uses her powers to trap her in a cage; she then imprisons her and the dogs and summons food for the dogs to feed Red. Two years pass and Red is very obese; the witch turns into a frog and eats her, after which she then informs the dogs that she's still hungry. The dogs try to persuade her not to eat them and they tell her that they just want some cheese; she summons some easy cheese and sprays it on them and she shadow engulfs them and we hear chomping and gulping sounds. In the ending title card, it shows them and Red inside her stomach surrounded by the digestive acids.
 * The first episode of season 2 of My Little Pony Friendship Is Magic ends with Discord having successfully broken and brainwashed almost the entire main cast except for Twilight Sparkle, pretty much destroying their friendship in the process. He tricks Rainbow Dash into breaking the rules of the game via a Sadistic Choice, handing himself victory in his little "game". The episode ends with Twilight Sparkle watching in shock as Discord lets loose a storm of chaos on Equestria. Sure, things get better next episode, but that was still a very bleak way to end an episode!
 * Nowhere near as harsh, but still relevant is the first episode of the first season. Nightmare Moon has returned; Twilight Sparkle saw this coming, but failed to prepare; Princess Celestia is nowhere to be seen.
 * Of course, both examples only tell the first half of their stories, giving them more in common with Darkest Hour (literally, in Nightmare Moon's case).
 * When the Wind Blows, the main characters survive a nuclear bombing, but are obviously dying of radiation poisoning. They remain in denial with complete faith that help will arrive and save them. Even in the end they have a semi-optimistic tone, but have clearly given up as they crawl into their paper bags and into their shelter to die.
 * Episode 26 of Scooby Doo Mystery Incorporated. The Freak of Crystal Cove turns out to be Fred's dad, the Mayor, who we now learn isn't Fred's dad at all and was trying to find the supposed treasure of Crystal Cove. Fred had proposed marriage to Daphne, but that's now in indefinite abeyance as he's out to find his real parents and who he really is. Velma is now on everyone's sh*t list for not coming clean about Angel Dynamite's real identity (original Mystery Inc. member Cassidy Williams), Shaggy is getting sent to military school, and Scooby is being sent to a farm. Original Mystery Inc. mascot Professor Pericles has made off with both segments of the Planispheric Disc (telling the whereabouts of the treasure), and the episode--and season--ends with Scooby vowing to hunt down Pericles and reunite the gang.
