History DownerEnding / WesternAnimation

** Two episodes that air together regularly, "Shark Bait" (the kids driving off tourists with a phony shark scare) and "A Shot in the Park" (Twister sneaking into a closed exhibit in a water park and loses his camera as a result).

** Two episodes that air together regularly, "Shark Bait" (the kids driving off rude tourists with a phony shark scare) and "A Shot in the Park" (Twister sneaking into an off-limits area of a water park, and leaves his camera behind as a result).

* ''WesternAnimation/RocketPower'' - "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". [[EarnYourHappyEnding 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 ending to ''If It Smells Like An Ed''. The first act had the Eds being accused of ruining Friendship Day (Ed stealing Sarah's paintbrush, Edd wiping Plank's mouth off and Eddy piercing the Heart of Friendship with a hockey stick), and tried to [[ClearMyName clear their names]]. Unfortunately, Act II has the Eds accused of [[BoundAndGagged 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. [[SadisticChoice 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 [[TheDogWasTheMastermind Jimmy, of all people, set them up]]. His motive? [[ChekhovsGun The wedgie]] (and subsequent humiliation) given to him earlier that day by Eddy. He then has the Kankers take the Eds away. The blow is softened somewhat after Jimmy slips on a Karma-placed banana peel, but still...

** "Dexter Detention" has Dexter breaking rocks at gunpoint after accidentally breaking into a prison.

* Several of the shorts in ''WesternAnimation/MickeyMouseWorks'' qualify as such:

* 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.

* The ''WesternAnimation/TeenTitans'' 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/YoungJustice'' has quite a few:

** The ending of "Frost & Fire" certainly qualifies. In the end, Finn writes fake letters to Flame Princess and Ice King, each written from vice versa's point of view, to have them fight, because when they fought earlier it caused Finn to have wet dreams about it, and it's also very important as well because the Cosmic Owl is in it as well. After he completes his dream, he reveals the truth to Flame Princess and Ice King. The results: [[spoiler:Flame Princess is so hurt and depressed she dumps him]] (How [[spoiler:depressed]], you may ask? She can only hear Finn's attempt of an [[spoiler:explanation]] as "waa waa waa"s), and the Ice King just says "Pssh, [[spoiler:you BLEW it]], man!". Then in the next episode, "Too Old", Finn went back to attempting to win Princess Bubblegum's heart one last time, and realized Flame Princess was the one for him, but Jake ominously stated she might have moved on. The arc was concluded with the episode "Earth & Water", where Flame Princess once and for all officially dumped Finn. And she made it very clear in "The Red Throne" that she no longer loves Finn because he was still acting like a dick trying to win her back.

** 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]]; 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 as Invictus escapes from Final Space in its true form, now free to conquer every timeline.]]

** "Escape from the Citadel" is pretty bad. Finn has finally found one of his actual parents, meaning he's not the last human anymore, but his father wants nothing to do with him and tries to get away. Finn's grass sword attaches to the ship Finn's father is on, but the grass sword, and Finn's entire arm, get pulled off, and his father escapes. The only good thing to happen is that the Lich has been changed into an ineffective humanoid form, but how long will that actually last for someone like the Lich?

** In the penultimate episode of season 3 has both Bojack and Sarah Lynn go on a drug bender, which results in both of them realizing more about themselves than they did sober; they go to a planetarium, where after Bojack ponders their experience in the universe, [[spoiler: Sarah Lynn dies in his arms from a drug overdose.]] Season 6 then reveals that [[spoiler: she was actually just barely alive at that time, and Bojack waited 17 friggin' minutes until he could call an ambulance. THEN she dies in the hospital.]]

** "The Eyes": "I'm...still not happy."

* ''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. What's worse, this would be the last time viewers got to see her, too.

** "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, in 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.

* ''WesternAnimation/TheSimpsons'' episode "Homer's Enemy" famously ends with Frank Grimes failing to expose Homer for the fraud he is, losing his sanity and [[HighVoltageDeath electrocuting himself.]] Worse, everyone laughs with Homer at his funeral.

* ''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.

** 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 Stella who is now in tears. The tragedy of it all is somewhat dampened by the fact that this is a ShoutOut episode: Dr. STEELLLAAAAAA!!! hid her Frankenstein's lab in the Bates Motel, while Clayface himself resembles an Oscar statue.

* The last episode of ''WesternAnimation/HomeMovies'' 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 filmmaker because he believed that his movies shouldn't be watched, despite producing impressive material for an 8-year old with a cheap camcorder.

* ''WesternAnimation/{{Hilda}}'': "The Ghost" ends not only with the search for Frida's book amounting to nothing more than a wild goose chase, but Hilda, David, and Frida's friendship becoming severely strained, if not outright severed.

** Then there's [[spoiler:episode 37. Cassidy forms an uneasy alliance with the gang to trace the origins of Germanic robots that tried to kill her earlier in the episode. They (along with 1967 H-B stars Tom, Tubb, Scooby the seal and their Moby Dick submarine) find their way to an underwater city that was the original Crystal Cove settlement. The show's villain, previous Mystery Inc. mascot Professor Pericles, is the culprit and before escaping he sets off detonation charges. Cassidy stays behind so the rest can escape in the sub, but a shattered diving helmet and the official word from producer Tony Cervone is that Cassidy did not survive. The episode ends with the gang mourning Cassidy.]]

* The animated short ''{{WesternAnimation/Alma}}'' ends with Alma becoming trapped inside the body of a doll, alongside many other children who have met the same fate, and [[HereWeGoAgain another doll appearing in the storefront to lure in the toy shop’s next victim.]]

** Similarly, "Batty Baseball" had a running gag of a baseball catcher constantly creeping up in front of the batter and catching the pitch as the batter swings. The next-to-last scene has a zoom-in of the batter as he swings followed by the ghastly sound of breaking. The scene goes dark as the announcer intones "And now, a moment of silence" with the catcher ascending to Heaven with the "Sad ending, isn't it?" sign.
