History MoodWhiplash / AnimeAndManga

* There are ''plenty'' of scenes in HighSchoolOfTheDead where really serious and dramatic scenes will inexplicably cut to a panel of unleaded FanService. Occasionally, horror and fanservice will be shown ''in the same panel.''
* The {{Jack and the Beanstalk}} anime film does this from time to time, it starts out rather cheery and upbeat, once Jack gets to the beanstalk the mood changes after he meets Princess Margaret, after she sings a love song she introduces him to her "mother" a witch named Madame Hecuba who kidnaps children and feeds them to her ogre son Tulip, she has also taken over the kingdom of the clouds, murdered Margaret's parents, turned most of the servants into mice, and put Margaret under a hypnotic spell to which she will marry Tulip and inherit the castle.
* ''FutureGPXCyberFormula'' occasionally shifts from funny moments to serious and intense racing scenes and back. The OVA sequels does this from time to time, although even less than the ones that followed, especially with ''ZERO'' and ''SAGA''. Then ''SIN'' came along, which promptly smashed this trope into a million pieces.

* ''RurouniKenshin'', similar to ''FullmetalAlchemist'', tends to have abrupt moments of comic relief interspersed with heavy drama and/or intense fight scenes. Compared to the manga, the anime adaptations have taken opposite approaches to this: the TV series significantly ups the comic relief, while the OVAs practically eliminate it

* ''FutureGPXCyberFormula'' occasionally shifts from funny moments to serious and intense racing scenes and back. The OVAs also does this occasionally from time to time, especially with ''ZERO'' and ''SAGA'', but ''SIN'' promptly kicks this trope in the teeth and castrates it for good measure.

** The show is largely a run-of-the-mill {{Shonen}} series up until [[spoiler: Episode 18]], which was made around the time Hideaki Anno [[CreatorBreakdown had a massive psychological crisis]] involving depression that he had to go into therapy for. Episodes after this "epoch" are noticeably darker, bloodier, and sadder than the previous episodes. MoodWhiplash? Oooooh yes.

** The whole series is an expert in Mood Whiplash as it often turns a funny or cute scene into a surprising or even nightmare bringing scene. What is creepy in the anime is often scary or terrifying in the manga where you sometimes almost don't dare to turn to the next page. Like in Onikakushi-hen chapter 3 (in where there are no less than 4 changes in mood in just a few pages) when Keiichi confronts Rena about her and Mion keeping secrets from him only for Rena to turn the tables on him and instead accuse him of keeping secrets from his friends. It's all seems to be end peacefully when Rena calms down, until you turn the page and see this [[http://manga.animea.net/higurashi-no-naku-koro-ni-onikakushihen-chapter-3-page-30.html]], complete in colour and all. It is without warning and you have to read carefully to even notice that the page before was also in colour. And now imagine a series full of similar things...

* ''{{Trigun}}'' marks the end of its comedic side with the introduction of Legato.

* OsamuTezuka did this ''all the time''. Whether it was random insertion of himself into the procedings, an inappropriate appearance by Hyoutan-Tsugi (aka "Gourdski"), a bit of over the top anachronism, or just some plain slapstick, you could rely on Tezuka to insert a bit of humour in all but his most serious stories. To quote a review of ''Buddha'':

* ''Sonic X'', the original version, at least, has a fairly emotionally heavy ending to the second season, what with [[spoiler: Sonic explaining to Chris why he stayed behind and Chris's reaction]]. Following into the dub-only season 3, which starts with... a really bad pun.

* AngelBeats frequently uses this. For instance, most of Episode Two involves the SSS members getting temporarily killed in increasingly bizarre and amusing ways (for the most part, no one can really die in AngelBeats due to the fact that they're already dead, so this is PlayedForLaughs), but eventually, when it's just Yuri and Onatashi, Yuri starts talking about how [[spoiler: when she was a little girl, her three younger siblings were killed by robbers right in front of her, one by one, because she couldn't find any valuables to give them.]]

* ''CodeGeass'' often had this, either ending comic episodes on a jarring twist or following a BreatherEpisode with a tragic WhamEpisode. A fairly low key example early in the series was a humorous episode about trying to catch a stray cat that got Zero's mask stuck on its head, which ended with the Emperor delivering an unsettling Social Darwinist speech broadcast on every television in Britannia, talking about how evil equality is. The kicker was in the second season where the very last comic episode focuses on [[spoiler: Milly's graduation celebration, where boys wear blue hats and girls wear pink hats, and if someone steals someone else's hat and puts it on, those two have to become boyfriend/girlfriend. There had been a [=~Will They Or Won't They~=] looming over Shirley and Lelouch for the entire series until that point, when Lelouch essentially handed his hat over to Shirley, showing that he was finally willing to return her feelings]]. The episode ended with [[spoiler: Shirley regaining her memories, causing her to become aware of Japan's and Britannia's ThirtyXanatosPileup (and remember that she had tried to murder Lelouch after he killed her father the previous year), leaving her with literally nobody to trust. ItGotWorse]].

** The series first Cerberus moment came when Soul got cut across the chest by Ragnarok. It's followed up by the fight between Crona and Stein and Death Scythe, which flips between the brutal and the comedic. Contrast Spirit stabbing Crona so that they are hanging from the blade or Stein blowing a hole through Crona's chest, with Crona and Ragnarok nonsensical mid-battle arguments and the bit where they wonder what to do with the stars circling Crona's head after being kicked by Stein.

&feature* A more recent example is PuellaMagiMadokaMagica's Episode 3. The first 2 episodes managed to set a fairly dark mood, but still pale in comparison with the end of episode 3.

* ''SoulEater'' It doesn't happen all the time, but there are a few points in Soul Eater where the mood will do a complete 180 at the drop of a hat. [[http://www.youtube.com/watch?v=-GXVZYEH8LY&feature=related sometimes even less]]

* ''Sonic X'', the original version, at least, has a fairly emotionally heavy ending to the second season, what with [[spoiler: Sonic explaining to Chris why he stayed behind and Chris's reaction]]. Following into the dub-only season 3, which starts with... a really bad pun.

** Speaking of Gundam, the ongoing story arcs from the parody manga ''Gundam-San'' are the absolute king of this. Best example would probably be ''Garma of the Space Island'', a goofy SliceOfLife story about the [[BigScrewedUpFamily Zabi clan]] as a poor family living in a Japanese-style shack. Things take a turn for the worse after Zeon Deikun shows up, but the absolute biggest AudienceSuckerPunch comes when [[spoiler:it turns out the whole thing was Kycilia reminiscing about her dead family, right when Char shows up to deliver her [[BoomHeadshot memorable death scene]].]]

*** And after that's over we still have half of ''Gurren Lagann'' left, and it'll be followed by the [[{{Gorn}} ultra-violent]], [[ShootTheShaggyDog super-depressing]], [[SoBadItsHorrible often very-disliked]] ''MDGeist''.

** During the episode itself was a spectacular MoodWhiplash. [[spoiler: You have Mami and Madoka sharing their sincerest feelings with each other, both of them feeling inspired after the conversation. Mami dies gruesomely five minutes after.]]

* The OVA of Johji Manabe's ''Capricorn'' has this in spades. One example: The CuteMonsterGirl happily flies an OrdinaryHighSchoolStudent out of the BigBad's castle like they're close friends and nothing's wrong, but turns panicky when {{mooks}} start chasing after them, and then she gives same student the cold shoulder when he tries to talk to her soon afterward. And the [[ManBehindTheMan evil general]] the masses know is manipulating the king [[AttentionDeficitOohShiny still cheer for him at a massive rally]] as he takes control of the planet. As it's a 45-minute adaptation of an entire manga series, however, these kinds of issues are [[AdaptationDecay to be expected.]]

* ''Sonic X', the original version, at least, has a fairly emotionally heavy ending to the second season, what with [[spoiler: Somic explaining to Chris why he stayed behind and Chris's reaction]]. Following into the dub-only season 3, which starts with... a really bad pun.

* There's a five-episode OVA called ''Master of Martial Hearts''. The first four are fanservicey breasts-and-panties fighting anime stuff. The last episode is a neck-breakingly-fast shift into hard drama. It's as though someone called for a deconstruction in the planning stages and they didn't get to it until the end (though there ''are'' minor hints in that direction early on).

* ''SailorMoon'' mixes action, romance, and lots of comedy, so this isn't surprising. SuperDeformed slapstick in the middle of serious scenes, as well as shameless pantyshots could be {{narm}} or NarmCharm.
