History WhamEpisode / AnimeAndManga

* ''Manga/TheSummerYouWereThere'' has Chapters 14 and 15. In the former, Shizuku, accompanied by her "girlfriend" Kaori, goes to visit Ruri, the girl Shizuku bullied in elementary school, to apologize, but Ruri politely [[RejectedApology rejects the apology]], saying that she still bears the emotional scars of the bullying and wants nothing more to do with Shizuku. Shizuku takes this relatively well, but as Ruri and her best friend Seri are leaving, Kaori collapses. An ambulance takes Kaori away, and as Seri accompanies Shizuku to the hospital, she tells Shizuku that Kaori has a chronic respiratory disease. At the hospital, Kaori confirms what Seri said, and tries to break up with Shizuku to spare her the pain, since she knows she is dying. The tone of the story is significantly darker from this point forward, as Kaori is almost constantly in the hospital and fully aware that she most likely has less than a month to live.

* In Chapter 16 of ''Manga/TegamiBachiLetterBee'', Lag encounters his old friend Gauche, and learns that he lost all his memories, joined an anti-government organization as a "marauder," and has a mysterious girl with him who has the same name as the dog that used to be his dingo.

** The second half of Season 2 attempted to make ''every'' episode a WhamEpisode, with a constant series of turning points. [[BrokenBase Some people liked it for its quick pacing and unexpected developments as several characters were pushed to their respective limits, and some people called it "trainwreck" due to the fact that various events were often given too little explanation and the specific details of the story seemed to take a backseat to the plot twists]].

* ''Anime/CodeGeass''}
** Episode 22. Just when it seems like peace is about to be brought between Britannians and Japanese with the formation of the Special Administrative Zone of Japan, Lelouch's Geass activates without his conscious input while he's talking to his sister and Britiannian princess Euphemia about what said Geass can do...and it so happens that the Geass activates while he's talking about how he could hypothetically order her to kill all the Japanese. "Hypothetical" turns into "reality" when she then has a stadium full of Japanese massacred horrifically, undoing all her efforts to end Japan's status as a territory of Britannia.

* ''Anime/CodeGeass'' has several wham episodes but one of the most prominent examples is Episode 22. A thirty second scene caused a certain character's personality to take a radical turn, making both the cast and the audience get on an emotional roller-coaster. Depending on what camp you fall into, at this point the show either just fell flat on its face, [[GrowingTheBeard marked the start of an engaging climax that took the existing conflict to the next stage]], or simply combined RuleOfCool and RuleOfFunny in an over-the-top but still entertaining way.

** In episodes 16 and 17 of ''[=StrikerS=]'', Jail Scaglietti's forces attack Riot Force 6's base and the site of the press conference, abducting Ginga and Vivio (after almost killing the first) and showing the power of the Combat Cyborgs. During this attack, it is revealed that the Nakajima sisters are also combat cyborgs.
** Chapter 7 of ''Force'': the manga starts off as a slighly DarkerAndEdgier version of ''[=StrikerS=]'' and then Cypha of Hückebein goes and kills the EnsembleDarkhorse LadyOfWar Signum and her [[FairyCompanion Unison Device]] Agito. Well, not quite, they both get better (hopefully), but this was the first time a main cast member was put through a NearDeathExperience in the main story (as opposed to flashbacks).

** Chapter 40. The implications of [[spoiler:Big Sis' actions in the past are now also catching up to the present, when her [[CloningBlues rogue, self-aware clone she created from her cloning ability]] drove the free world she crafted into chaos as it attempts to grant humanity the power [[RealityWarper to change themselves]], which occurs in the form of a feedback loop]]. This resulted in [[spoiler:yet another chaotic imbalance to the already warped world]].

* [[Manga/GiantRobo Giant Robo: The Day The Earth Stood Still]]: The end of Episode 3. Daisaku and Giant Robo finally arrive at the battlefield, Daisaku gives a speech about how he can never forgive the evil Professor Vogler and orders Robo to attack the Vogler Sphere. But when Robo punches it....his arm ''completely shatters''. [[spoiler: Episode 4 and 5 also has several characters KilledOffForReal in sometimes very brutal and sudden ways]].

* ''Anime/PantyAndStockingwithGarterbelt'': Episode 12, in particular the segment ''Panty+Brief", where it is revealed that Brief is [[spoiler:[[OhCrap instrumental to the Big Bad's plan]]]], on top of one of the character losing her powers and another returning to Heaven.

** EP-021 "Bye-Bye Butterfree". Ash release Butterfree, the first times he's ever released a Pokemon. Given the themes of friendship and GottaCatchThemAll the series had, none saw this coming.

** DP-061 "Team Shocker!". [[spoiler: Jessie finally wins a Contest. Not only does this set up a HeroicBSOD for Dawn that sets up her CharacterDevelopment, but it paves the way for [[TeamRocketWins Team Rocket being legitimate rivals in later performance competitions]].]]

** Fans were ''floored'' in the BW arc, when [[spoiler:White's star Pokémon actress, Gigi the Tepig, willingly ''ditches'' her to go off with N. The shock was enough for White to accidentally slip out of the Nimbasa Ferris Wheel, leaving her to fall hard on the ground, barely conscious and her [[DullEyesOfUnhappiness blank eyes]] full of tears. Considering how the rest of the franchise seem to have Pokemon unconditionally love their trainers no matter what, it was an especially big shocker.]]

** The biggest wham chapter was arguably the final one of the FRLG Arc, where just as you think the heroes have won against Team Rocket, even Mewtwo relaxes and then [[spoiler:five of the manga's most popular and capable protagonists (Red, Blue, Green, Yellow and Silver) are all turned to stone indefinitely by a mysterious light by the Team Rocket member Sird, who escapes.]]

* Episode 6 of ''Anime/BloodC''. Episodes 1 through 5 followed [[StrictlyFormula the same formula,]] sing on the way to school, play with the puppy, eat with friends, fight and kill the MonsterOfTheWeek. 6 takes the formula and shatters it, with [[spoiler: the deaths of Saya's friends Nono and Nene]] and several townspeople in a rather shocking bit of DaylightHorror.

** Ch.1 produced a wham effect in the Japanese readers when it was first published: many that flocked to see Creator/TakehikoInoue's new series were shocked to see that it was a significant depart from his previous light-hearted series (''Anime/SlamDunk''). Right from the very start of the series, ''Vagabond'' shows brutal images where Takezō savagely kills some soldiers.

* ''LightNovel/TheFamiliarOfZero'': Episode 10 of season 4. The Ancient Dragon shatters Saito's trusty TalkingWeapon Derflinger, then eats UsefulNotes/ThePope. Everybody is forced to run, full of despair.

* Episode 10 of ''LightNovel/HeavensMemoPad'' ends with [[spoiler:Ayaka's suicidal leap of the school building]].

* In ''LightNovel/KokoroConnect'', [[spoiler:in episode 5, when Heartseed takes over Iori's body and jumps off the bridge]].

* The anime of ''Anime/WelcomeToTheNHK'' has this for episode 13. Sato shows one of the first major signs of overcoming his {{hikikomori}} disorder when his senpai Hitomi (who he's very attracted to) seems to invite him on a vacation with her, but finds out that she has inadvertently taken him with her to a group suicide party AND has a boyfriend who proposes to her to convince her not to kill herself. This leads to him actually attempting suicide himself, since he was using her as motivation to change. In the chaos that follows, Misaki desperately attempts to save him, which leads to her showing the first real sign of her ''own'' issues. By the end of the episode the Misaki and Sato are so emotionally battered that they burst out in [[InelegantBlubbering combined wails]] that carry on to the end title card.

** Episode 25'[[note]]Part one of ''The End of Evangelion''[[/note]]: Shinji visits Asuka in the Hospital, [[spoiler: after trying to drown himself]], looking for comfort. Asuka unresponsive, Shinji takes out his frustrations by [[spoiler:[[ADateWithRosiePalms masturbating]] [[DudeShesLikeInAComa over her comatose body]]. Even he points out that he is "The lowest of the low". The dubbed version has Shinji say, "I am ''so'' [[PrecisionFStrike fucked up]]"]]. [[FromBadToWorse And that's only the first five minutes]].

* ''Anime/KillLaKill'' has quite a few of these, but Episode 18 is probably the standout example. After spending over half of the series as an antagonist, [[TheRival Satsuki]] rebels against her mother, [[BigBad Ragyo Kiryuin]], revealing that she played the EvilOverlord as part of her revenge for the death of her [[YouKilledMyFather father]] and unnamed little sister, both of whom Ragyo disposed of. Ragyo survives said assassination attempt, revealing to be [[HumanoidAbomination fused with the Life Fibers]], and [[NoHoldsBarredBeatdown hands Satsuki her ass]]. After removing her Kamui and disposing of her, she turns her attention to the protagonist, Ryuko Matoi, by ripping her heart out and revealing that she too has been fused with Life Fibers, [[LukeIAmYourFather making her the aforementioned unnamed little sister who Satsuki thought was dead]].

* In ''Manga/MurasakiiroNoQualia'', Chapter 6 finally reveals the pecularities brought along with Yukari's eyes. And... they're creepy, at the very least.
** Chapter 10:
-->"This is the PointOfNoReturn. Administrivia/YouHaveBeenWarned."
** Actually, the series is full of [[WhamEpisode Wham Episodes]], a natural conseqeunce of SerialEscalation.

** Episode 9: Ayano's backstory is revealed, and [[spoiler:Kenjirou is actually possessed, we learn Kano knows about Kenjirou, and [[GirlInABox Ene's former body cameos at the end]]]].

** Before that, we have the discovery of the {{Sixth Ranger}}s. While Kari being the child was a ForegoneConclusion to many, TheReveal that Gatomon, Myotismon's most loyal servant, was her digimon, came as a surprise to plenty.
