History Cliffhanger / WesternAnimation

* The [[WesternAnimation/BattleTech animated series]] based on ''TabletopGame/BattleTech'' ended after the first season, so it was never explained what happened to the population of Sommerset after the battle between the Strikers and Nikolai Malthus. The official canon of the game states that the series is a [[TakeThat poorly received]] docudrama based on the Clan invasion in-universe, so there won't be a straight answer from that vector. Of course, the game also states that Sommerset was [[CanonDiscontinuity never evacuated in the first place, either.]]

* In ''WesternAnimation/DannyPhantom'''s season 3, Valerie found out that [[spoiler:her employer is half-ghost and that Dani is half-human]], but after that episode, nothing was ever heard of this ever again. In fact, Valerie practically fell off the face of the earth for the much of that season.
** Long story short: ExecutiveMeddling.

* ''WesternAnimation/YoungJustice2010'' was unfortunately cancelled, and to infuriate fans more than anything else, the finale ended on a ''massive'' cliffhanger. The cliffhanger? [[spoiler:Darkseid.]]
** Fortunately, this cliffhanger will soon be resolved thanks to the show being UnCanceled for another season.

* ''WesternAnimation/TheRuffAndReddyShow'', ''Q.T. Hush'', ''Western Animation/TomTerrific'' and ''WesternAnimation/CrusaderRabbit'' were four other shows featuring cliffhangers. The middle two shows had five-episode cliffhangers while ''Ruff'' ran through 13 episodes and ''Crusader'' blazed through 20 episodes.

* ''WesternAnimation/WolverineAndTheXMen'' ended on a ''HUGE'' one at the end of Season 1. Even though the BadFuture involving the Sentinels was successfully averted, there was '''[[HereWeGoAgain ANOTHER]] one involving Apocalypse, Mister Sinister, and a [[BrainwashedAndCrazy mind controlled Cyclops]]. Not to mention, as part of setting up this arc, Angel was brainwashed and turned into Archangel by Mister Sinister and never got broken out of his control.

* The first episode of ''WesternAnimation/PepperAnn'' ended with "To be continued...". Strangely, there was no second part to that episode.

* Happens in ''WesternAnimation/TheSimpsons''. "[[Recap/TheSimpsonsWhoShotMrBurns Who Whot Mr. Burns?]]" does this as an obvious homage/parody of ''Series/{{Dallas}}''.

* Parodied with ''WesternAnimation/ThePowerpuffGirls'' episode "I See A Funny Cartoon In Your Future." As a homage to ''Rocky & Bullwinkle,'' there is a break in the action tailing off with a cliffhanger (literally--the girls are hung over a cliff thanks to the antagonist employing three voodoo dolls of them), an EitherOrTitle, a faux commercial, then a resumption and resolution of the story.

** WordOfGod preferred it. But it's been resolved in the comic book, ''Comicbook/AvatarTheLastAirbenderTheSearch''.

* Zig-zagged: A handful of WesternAnimation/MightyMouse cartoons from the late 1940s and early 1950s with Pearl Pureheart and Oil Can Harry open with the resumption of a cliffhanger, when a previous episode never did exist.

* ''WesternAnimation/YoungJustice'' was unfortunately cancelled, and to infuriate fans more than anything else, the finale ended on a ''massive'' cliffhanger. The cliffhanger? [[spoiler:Darkseid.]]

*** "[[Recap/MyLittlePonyFriendshipIsMagicS2E2ACanterlotWeddingPart1 A Canterlot Wedding, Part 1]]" ends with Twilight being shunned by her friends, family and mentor. To make matters worse, "Cadence" banishes her to the caverns of Canterlot.

** From Wiki/ThatOtherWiki John Semper mentioned in an interview if he had continued on with the show, Spider Man would have gone through past time periods and found Mary Jane in Victorian England. Spider-Man would battle with the real Carnage portrayed as Jack the Ripper.

* The pilot episode for the obscure show/toy line ''Computer Warriors'' ends on one. The viruses who are the villains have been trapped on CD's, but they're picked up by the owner of the computer they all came out of and taken over to a friend's house. The Computer Warriors fly into cyberspace to intercept him, going out on a ToBeContinued. It's unclear if this was only ever meant to set up the plot and the kids at home were supposed to finish the story by playing with the toys, or because the line didn't do very well.

* ''WesternAnimation/{{Duckman}}'' ended with three characters -- Duckman included -- getting hitched, and [[spoiler:his late wife Beatrice suddenly appearing alive and well at the end]]. Writer Michael Markowitz seems unwilling to divulge the ending, leaving it up to the fans to guess what may have happened.

* ''WesternAnimation/GetEd'' ends with [[spoiler: [[CoolOldGuy Ol' Skool]] trapped in The Machine with [[BigBad Bedlam]], and "sent away" by Ed.]] The series was not picked up for a second season. [[AuthorExistenceFailure Creator Andy Knight's untimely death in 2008 twisted the knife further before driving the final nail in the coffin]].

*** "[[Recap/MyLittlePonyFriendshipIsMagicS2E25ACanterlotWeddingPart1 A Canterlot Wedding]]" ends with [[RealityWarper Discord]] successfully mind breaking the mane cast (who cannot activate their trump card in this state) and establishing a reign of chaos upon Equestria. Resolved in part 2 when Twilight gets the gang back together, allowing them to [[TakenForGranite put Discord back where he belongs]].
*** "[[Recap/MyLittlePonyFriendshipIsMagicS3E1TheCrystalEmpirePart1 The Crystal Empire, Part 1]]" ends with the reveal Twilight was wrong and they needed to find the Crystal Heart instead of making one, resulting in Cadance's power running out and King Sombra's shadow form washing over the Crystal Empire as the protective dome fails.

** "[[Recap/MyLittlePonyAndFriendsE58FlightToCloudCastle1 Flight To Cloud Castle, Part 1]]" ends with Heart Throb, Locket, Twilight and Garth thrown from the flying castle and sent flying at high speed towards a cliff.

*** "[[Recap/MyLittlePonyAndFriendsE33TheMagicCoins3 The Magic Coins, Part 2]]" ends on a literal one, with Megan and Wind Whistler perched on a narrow ledge above a lake of lava, with thermal updrafts too strong for Wind Whistler to fly in and their perch rapidly crumbling beneath their feet.

** Taken [[UpToEleven up to eleven]] in the episode "200" which ends with three separate cliffhangers.

* ''WesternAnimation/SpiderManTheAnimatedSeries'': The series got TurnedUpToEleven for the last season with Mary Jane getting kidnapped by Hydro-man, Spider-Man gives chase, and gets his ass handed to him, but that's OK because [[DeusExMachina MJ has Water powers now]]! But it turns out she's actually just a clone, then [[TheWatcher Madam Web]] comes in and says that Spider-Man must take part in a 3 episode StoryArc based on the [[TheEighties 80's]] limited series, ComicBook/SecretWars1984, after that he teams up with alternate versions of himself from other dimensions, to stop an evil version of himself that bonded with the Symbiote from destroying reality and gets transported to our dimension where he meets up with Creator/StanLee after that Madam Web vows to help him find the real Mary Jane... and that's it, that was the end of the last episode.

* ''WesternAnimation/TheOwlHouse'' played it straight at the end of "[[Recap/TheOwlHouseS1E18AgonyOfAWitch Agony of a Witch]]" and how! Eda is captured by Lilith, she sacrifices herself to save her own witch apprentice, and Luz came out of the episode crying, distraught over what just happened. The last thing viewers see is Luz completely heartbroken and the words "To Be Continued" over a black screen. By that point, the fandom would have rioted.

* ''WesternAnimation/TheAmazingWorldOfGumball'': The Season 6 finale ends on a ''literal'' cliffhanger; Rob is hanging off of a cliff made by the void in Elmore Jr. High before falling into the void where the episode, and the series itself, ends.

* Though it is episodic and does have its rather odd ending scenes, ''WesternAnimation/BigCityGreens'' has its first huge cliffhanger occur in the Season 2 episode "Reckoning Ball" after Chip Whistler takes over for his retiring father as the CEO of Wholesome Foods. He reveals his apology to the Greens to get them to sign the contract which proves they forgive him for his mean deeds was only an act, and he used their innocence and gullibility to [[CorruptCorporateExecutive seize full control of the company]] and, since his dad is not around, is focusing on running them out of town sometime soon, setting him up as the ArcVillain for the remainder of the season.
* Subverted beautifully in ''WesternAnimation/FriskyDingo''. An episode ends with an almost literal cliffhanger as a woman is hanging from a ledge of a tall structure. Then, in the OnTheNext sequence, Killface says "Oh my God, she fell."
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' does this with the two-parters at the start of seasons 1 and 2, both of which involve a [[BigBad supervillain]] escaping confinement and needing to be put down with the Elements of Harmony. Both endings are also directed in a similar way, [[http://bronies.memebase.com/2011/09/22/my-little-pony-friendship-is-magic-brony-went-crazy-after-both/ which did not go unnoticed]].
** Season 1's first episode ends with the return of [[MadGod Nightmare Moon]]. The only forces capable of putting a stop to [[TheNightThatNeverEnds her plan]] are either inactive or nowhere to be seen. Resolved in part 2 when the Elements of Harmony are reactivated and used to [[StealthPun save the day]].
** Season 2's first episode ends with [[RealityWarper Discord]] successfully mind breaking the mane cast (who cannot activate their trump card in this state) and establishing a reign of chaos upon Equestria. Resolved in part 2 when Twilight gets the gang back together, allowing them to [[TakenForGranite put Discord back where he belongs]].
** WordOfGod says the season 3 finale is actually going to be continued in season 4, making it a 3-parter. The 2-part season 4 premiere serves as parts 2 and 3.
** All remaining Seasons followed suit; surprisingly, Season 7 is the only one to not begin with a 2-parter, and the Season 8 finale ends with this, which continues into the Season 9 premiere. The season 9 premiere ends with one as well.
* The first ''WesternAnimation/{{Futurama}}'' film ends with Bender's screwing up the time line of the whole film and causing [[TimeCrash a tear in the universe.]]

* Even though ''WesternAnimation/MyLittlePonyPonyLife'' is a slice-of-life show unlike its predecessor, they somehow managed to do a cliffhanger in one episode...
** The season 1 episode, "The Great Divide", has Twilight, Pinkie, Fluttershy, Rarity, Applejack, and Rainbow Dash realizing that competing isn't how friendship works and are worried they might hurt each other's feelings. Just as they are ready to quit, the games have commenced leaving all six ponies hopeless. [[MoodWhiplash Cue happy credits music]].

* The Season 6 finale for ''WesternAnimation/TheAmazingWorldOfGumball'' ends on a ''literal'' cliffhanger; Rob is hanging off of a cliff made by the void in Elmore Jr. High before falling into the void where the episode, and the series itself, ends.
