Over the years, anime and manga has produced a ''lot'' of wham episodes.

Works with their own pages:

* WhamEpisode/AttackOnTitan
* WhamEpisode/{{Bleach}}
* WhamEpisode/DragonBall
* WhamEpisode/FairyTail
* WhamEpisode/FromTheNewWorld
* WhamEpisode/FushigiYuugi
* WhamEpisode/GuiltyCrown
* WhamEpisode/{{Inuyasha}}
* WhamEpisode/MahouSenseiNegima
* WhamEpisode/{{Naruto}}
* WhamEpisode/OnePiece
* WhamEpisode/PuellaMagiMagicaSeries
* WhamEpisode/RurouniKenshin
* WhamEpisode/TheSevenDeadlySins
* WhamEpisode/YuGiOhArcV

!!Other series

* ''Manga/Acca13TerritoryInspectionDept'' episode 7 has the revelation that [[spoiler: the main character Jean Otus, who believed himself to be normal, is actually the heir to the throne]].
* ''Manga/AhMyGoddess'' maintains the status quo for 20 years. Keiichi and Belldandy are the exemplars of the ChastityCouple. And then in chapter 285, Hild explains that [[spoiler: Keiichi's mind has been altered by the forces of heaven to prevent the relationship from developing further. Apparently, the goddesses knew all along.]] It may take readers a while to sort this all out.
* ''Manga/AngelicLayer'' contains a giant one in episode 24, though it's for a character rather than the viewers. [[spoiler: At the end of the episode, the champion of Angelic Layer reveals that she is Shuuko, Miskai's mother, who Misaki hasn't seen in years.]] Episode 25 then shows the impact of it resulting in a brilliant tearjerker episode in an otherwise light hearted show.
* In ''{{Literature/Another}}'', episode 3 ends with the cute ClassRepresentative Yukari Sakuragi [[ImpaledWithExtremePrejudice dying]] [[CruelAndUnusualDeath horrifically]].
** [[FromBadToWorse All hell breaks lose]] in [[spoiler: episode eleven]] when the rest of the class hears [[spoiler: the tape from years ago which says the only way to stop the calamity is to kill the ghost student]]. In their fear-stricken panic, they all decide that [[spoiler: Misaki Mei]] is the extra student and [[spoiler: [[AxCrazy go batshit insane]], chasing her around the creepy hotel trying to murder her. They accidentally kill their own teacher, who tries to protect Mei, and [[CruelAndUnusualDeath two of the students end up dead]] during the chase.]] There are at least [[spoiler: three other murders/deaths]] outside of that incident in this episode as well.
* Chapter 128 of ''Manga/AssassinationClassroom'' starts up a series of revelations that change your understanding of certain characters and the payoff of tons of {{Foreshadowing}} so subtle, that most readers never even suspected anything. And the kickoff for all of this: [[spoiler: the reveal of Kayano having tentacles.]]
** Chapter 129 expands on the twist from the previous chapter. [[spoiler: Kayano is actually Akari Yukimura, a talented child actress who was the younger sister of Class E's previous teacher, Aguri. And said teacher, she's '''the woman who inspired Koro-sensei to become a teacher'''.]]
** Chapter 133: Koro-sensei decides to finally tell the story of his past, starting with the revelation that [[spoiler: he used to be the "Reaper"]]
** Chapter 134: [[spoiler: We finally see what Koro-sensei looked like, "Shiro" is revealed to be the lead scientist of the experiments that turned him into a monster, and the Reaper who was defeated by Karasuma was the apprentice of the original Reaper, who sold him out in order to take the name for himself.]]
** Chapter 138: [[spoiler: The moon explosion was not Koro-sensei's fault. It was actually caused by an experiment, which reveals not antimatter lifeforms such as Koro-sensei not only have a drastically reduced lifespan, but also cause a giant antimatter explosion when they die naturally, which puts a new spin on Koro-sensei's previous threats of destroying the world.]]
** Chapter 164: The beginning of the end. [[spoiler: The government reveals that they've been working on a KillSat that can kill Koro-sensei and they've trapped him on the mountain until they can fully charge it. They also expose his existence to the public in order to demonize him as the monster who held Class E hostage.]]
** Chapter 173: [[spoiler: Kayano is fatally impaled by the second Reaper. In front of [[BerserkButton Koro-]][[RageBreakingPoint sensei]].]]

* Episode 9 of ''LightNovel/{{Baccano}}!'': Want to know what happened in the time gap between the end of episode 2 and when Jacuzzi discovered the bodies? [[http://www.youtube.com/watch?v=d_1VgAH_xYI Well, now you do]] ([[{{Gorn}} Not for the faint of heart, we assure you]]).
* ''Manga/{{Bakuman}}'' has a few.
** Chapter 53: [[spoiler:Detective Trap, the main characters' first series, gets canceled]].
** Chapter 64: Azuki confronts Mashiro about the secrets he kept from her, and then hangs up on him when he is unable to provide a satisfactory explanation, leading them to temporarily break up.
** Chapter 100: Seven words: [[spoiler:"[[WhamLine PCP isn't going to get an anime]]"]].
** Chapter 130: [[spoiler:Someone re-enacts a prank that was discussed in Perfect Crime Party, and it gets on the news. Since the manga had a fair share of parents criticizing it for fear kids might imitate it, this does not bode well for it]].
** A few chapters later, [[spoiler: it's revealed that the manga Niizuma wants to end is Crow]].
* ''Literature/BattleRoyale''
** Chapter 3, which features [[spoiler: Yoshitoki's death]] an shows that AnyoneCanDie
** Chapter 10, which features the deaths of [[spoiler: Izumi, Ryuhei, Hiroshi, and Mitsuru]], the most of any chapter, and the revelation that [[spoiler: Kazuo]] is playing.
* The Eclipse (Volumes 12-13) arc of ''{{Manga/Berserk}}'' would have been the greatest wham ever, with the {{HSQ}} through the [[strike: roof]] stratosphere, had not the end of the Guardians of Desire arc (Volumes 2-3) just before the big Golden Age arc [[strike:hinted at]] essentially given away what would happen. It was, regardless, a very powerful GutPunch.
** More properly played straight in the anime, which cut out the Guardians of Desire arc altogether. Although the events of the Eclipse were strongly foreshadowed, the last few episodes still constitute a pretty powerful Wham.
** In Chapter 307, Femto uses the power of the Skull Knight's Sword of Resonance to tear open the bonds of reality, and merges fantasy and reality.
* ''Manga/BlackButler''
** It has quite a few of these, but probably the biggest example is the episode where Ciel goes back to England to find that it's on fire.
** The two chapters where Soma and Agni get attacked in the manor [[spoiler:and Agni locks Soma into a room, intent on keeping him safe, and blocks the entry, taking the full force of the attack. Agni dies]].
** The revelation that [[spoiler:there are ''two'' Ciels. Specifically, the Ciel that we know and his twinbrother]].
* ''Manga/BlackClover'' is normally a pretty idealistic series, with BlackAndWhiteMorality and villains with simple and straightforward goals. Then, Chapter 59 shows that we've just been seeing an island of honesty and kindness within them--outside of Asta's little group of Magic Knights (basically a wizard police force), there's widespread, systemic corruption within the organization in which the Magic Knights would physically assault and sexually abuse citizens for any reason they felt like, and the lack of accountability meant the Knights could always keep these incidents under wraps. These incidents are so common that they turned Zora [[MeaningfulName Ideale]] into the first true AntiHero of the series, and they're so widespread that Asta is the first genuinely good-hearted Magic Knight he met as an adult.
** The chapters starting from Chapter 142 pretty much form a line of wham episodes. [[spoiler: From William Vangeance being revealed as sharing the same body as Licht, the Wizard King then being killed, Licht being revealed as Patry, an elf boy who adored the real Licht, to the revival ceremony successfully bringing back the dead elves and causing most of the Royal Knights to be taken over by them. Things definitely won't be the same in the Clover Kingdom anymore.]]
* 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.
** And if you thought 6 was bad, 8 and 9 go straight past it with [[spoiler: a monster attacking the school and killing '''EVERYONE''' in Saya's class, even her friend Yuka. The only survivors are Saya, Tokizane, and Itsuki]]
** Add yet '''ANOTHER''' WhamEpisode with episode 11. To wit, [[spoiler: The Motoe Twins, Tokizane, Yuka, Itsuki, Fumito, and Kanako are all actors, and Saya's whole life in town was part of some twisted TrumanShowPlot.]]
* ''Manga/{{Bokurano}}'': Every time a detail is revealed about the battles that take place can qualify as part of a WhamEpisode. In particular, one occurring in both the second episode and chapter where it turns out whoever is chosen to be the main pilot for a battle dies as soon as the fight is over and still later when it is revealed that when a battle is over, whoever loses has their entire universe destroyed. Those two points end up setting the tone and sense of desperation for both versions of the series.
* In the adaptation of ''Manga/Brave10'', episode 9 packs all the punch. What would be a good night's sleep goes downhill when [[spoiler:Ana is revealed as TheMole for Hanzo, goes on to [[EyeScream cripple]] Rokuro (and forces him to sacrifice the important information in his MagicalEye) and Sasuke, and Yukimura reveals the reason why he wanted to gather the 10 Braves: to surpress the power of Japanese [[DestroyerDeity Death Goddess Izanami]]...incarnated into ''Isanami''. And she overhears that too.]]

* ''Anime/CardfightVanguard'' has; Ride 24, in which Misaki's parents [[WhatDoYouMeanItsForKids die in a flaming car wreck]]. Ride 32, in which [[TheBadGuyWins Team AL4 beats Team Q4 in the elimination round of nationals.]] Then there's Ride 41, in which Aichi becomes subverted by his PSY Qualia and starts to [[VillainProtagonist become another Ren]].
* Episode 17 of ''Manga/{{Chobits}}'', starts off like any other episodes. Then [[GratuitousNinja suddenly, right out of nowhere, ninjas]]! Scene cuts to the landlady sitting in an ElaborateUndergroundBase, tracking them through futuristic equipment. Cue end credits.
* ''Anime/ChronoCrusade'', ep 19. The BigBad has been subverted so far, everyone's enjoying a carnival...and Mr. BigBad himself comes out of nowhere, assembles all his {{MacGuffin}}s in one slick move, and accomplishes the very thing the heroes have been trying to prevent him from doing!
** This actually is based on a plot twist that happens in the manga--only the manga version has even ''more'' wham, since it also includes Chrono finally breaking down and snapping after ''years'' of mental anguish, flying into an UnstoppableRage that destroys part of San Francisco and ends with him having a HeroicBSOD that lasts for more than an entire volume!
* ''Manga/CityHunter'':
** Hideyuki's death changed the whole paradigm of the story.
** Whenever Ryo's acquaintances from the US show up.
* ''VisualNovel/{{Clannad}} ~After Story~'' episode 16. Even though the drama of the recent few episodes had revolved around the possibility, nothing can prepare you for the sheer impact of Nagisa's death in childbirth.
** And the same goes for ''~After Story~'' episode 22, where Tomoya initiates a TimeSkip thanks to the death of the girl from the illusionary world, who is actually Ushio after she loses her memories when she died, by obtaining a light orb, and using said light orb, travels back in time and is given a second chance to witness Nagisa's childbirth. This time around, she lives.
** The ''RecapEpisode'' of all things, can be considered a WhamEpisode because it's confirmed that the reality where Nagisa, Ushio, and Tomoya died really happened.
* ''Manga/{{Claymore}}'': Any chapter where Miria shows up is bound to be a whammer in some way or another. One of the most shocking so far is scene 79, when [[spoiler: she [[TheReveal reveals]] to the Seven Ghosts, Galatea, Clarice and Miata that the Organization has been the body responsible for creating the yoma, which they fight. According to her research, the mainland, which remains ambiguous to just about the entire population of the island, is in chaos due to an ongoing war. One side, the side in which the Organization originated from, decided to experiment with making elite super soldiers in order to combat the super soldiers of the opposing side (the Dragon Kin). In short (and put in Miria's words): the entire island is the Organization's laboratory. And those super soldiers in question? They're the Awakened Beings.]]
* ''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.
** 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]].
** The last five episodes of Season 2 were basically the collective wham of the entire series, with everyone's roles turned upside-down: Lelouch, former leader of [[LaResistance The Black Knights]], becomes the Emperor of his enemy [[TheEmpire Britannia]]; his former friend-turned-enemy Suzaku becomes his bodyguard; Kallen, who spent most of the show with a BodyguardCrush on Lelouch, chooses her beliefs over him and will stop at nothing to kill him; and Schneizel, Prince of Britannia, joins forces with the very organization Lelouch created. Also, after Lelouch's primary motivations for the first 90% of the show involved avenging his mother's death and creating a gentler world for his [[IllGirl blind, wheelchair-bound sister]], Lelouch discovers his LadyMacbeth mother's still alive and promptly becomes a SelfMadeOrphan, then creates a brutally oppressive regime bent on world domination, and when his [[MoralityPet beloved little sister]] begs him to stop, he makes it clear that he won't hesitate to kill her if it's convenient to his plans. And the clincher? [[spoiler: It's all an act to unite the world [[ThanatosGambit with his death]]. [[TheExtremistWasRight It worked out somehow]]]].
*** Well, in Kallen's defense, the only reason she chose to stand against Lelouch was because she believed he didn't care about her, not so much because she believed he was wrong. This is pretty much confirmed in her character poem, which states that had Lelouch spoken up at the time [[spoiler: their kiss]], she would have "followed him to Hell"; naturally, Lelouch knew that and so kept silent so that she would live.
** In ''Manga/CodeGeassNightmareOfNunnally'', a few happen toward the end.
*** Chapter 16: [[spoiler:Nunnally breaks her contract with Nemo and gets captured.]]
*** Chapter 20: [[spoiler:The Emperor has a coup to replace the established governments of the Areas with his own men, and moves to put his AssimilationPlot into action]].

* ''Anime/DanganRonpa3'' has Episode 9 of the Future Arc. [[spoiler:Juzo Sakakura is betrayed and murdered by his friend Munakata]] and [[spoiler:main character Kyouko Kirigiri trips her forbidden action and is poisoned to death]].
** Episode 10 of the Despair arc also qualifies, as it features [[spoiler:The brutal execution of Chiaki Nanami, the corruption of the rest of Class 77 into Ultimate Despairs and the [[TheStoic previously unshakable]] Izuru Kamukura ''mourning Chiaki's loss'']]
** The final episode of the whole anime, Side:Hope, certainly ends things with some major revelations, too. [[spoiler: All the members of Class 77 (sans Chiaki) come back to fight the brainwashed members of Future Foundation, led by [[SplitPersonalityMerge Hajime/Izuru]]]], and the major twist that ends the episode is [[spoiler: the return of Kyouko Kirigiri, her death in the Future arc [[OnlyMostlyDead not being as bad as it looked]]]]
* Episode 6 of ''Manga/{{The Daughter of Twenty Faces}}'' comes out of nowhere and sends earthquakes through the viewer's previous suppositions about the show and its content.
* Chapter 55 of ''Manga/DeadmanWonderland''. Up until this point, it's established that [[spoiler:Shiro has a SuperpoweredEvilSide known as the 'Wretched Egg.' And then clear out of nowhere, it turns out she never had a SplitPersonality at all; she faked the whole thing. Why? Because underneath it all, the sweet, bubbly, adorable ForgottenChildhoodFriend of Ganta's he knew and loved was actually a violent, hateful {{yandere}} who had never forgiven Ganta for abandoning her when he she needed him the most, and used the SplitPersonality act as an excuse to both be with Ganta as she was in her childhood, and exact revenge on everyone who had ever hurt her while making Ganta suffer in the same way she had by taking everything he loved from his past life away from him. And it gets worse: She did this because she wanted Ganta to eventually get strong enough to [[MercyKill put her]] [[DeathSeeker out of her misery]].]] '''[[TheWoobie Damn.]]'''
* The twenty-fifth episode of ''Manga/DeathNote'' tears away the [[UnspokenPlanGuarantee narrative mask]] over the BatmanGambit that Light sowed ten episodes before, and behind it is what most people consider Light's MoralEventHorizon [[spoiler:manipulating Rem into sacrificing herself by killing L and Watari]].
* Episode 21 of ''Anime/DennouCoil''. Turns out [[spoiler:Isako's brother was dead all along (she thought he was in a coma before) and she was strung along by Nekome.]]
* Episode 4 of ''Anime/{{Diebuster}}'': Up till this point, Nono has been basically a tag along to the Topless, hoping that she could gain her own [[HumongousMecha Buster machine]] to defend Earth from the Alien Monsters. When archaeologists on Titan discover what they believe to be an ancient, incredibly powerful Buster machine, Nono violates orders to get close to it. As punishment, the [[CreepyTwins Serpentine Twins]], Leaders of the Topless, send her on a SnipeHunt to Pluto to retrieve what may possibly be an intact Buster Machine, that crashed there some years previously. When the Titan excavation completes, three things are revealed simultaneously: The Alien Monsters they've been fighting up till this point aren't Alien Monsters at all, but part of a forgotten defense system designed to destroy threats to Earth; The "Buster Machine" on Titan isn't a Buster Machine at all, but one of the '''real''' Alien Monsters from Gun Buster; and that Nono is actually Buster Machine No. 7, the control unit for the Defense System and one of the most powerful Buster Machines in existence.
* ''Anime/DigimonTamers'' goes from fantasy-violence kiddy hero show to mind-rape extravaganza when Beelzemon kills Leomon, later following up with possibly the most destructive and disturbing BigBad in Digimon history, the D-Reaper, possessing Juri's voice, memory, and for a while, her very appearance.
** In ''Anime/DigimonAdventure'', we have Wizardmon's heroic sacrifice and subsequent death at the hands of Myotismon. For many, this was the moment when the show started GrowingTheBeard and showed a greater amount of depth than ever before.
** 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.
** ''Anime/DigimonSavers'' follows suit with the death of Merukimon and the reveal of Kurata's true intentions, as well as the past these characters share. It cements Kurata as irredeemable and from then on he just ''keeps getting worse.''
* ''LightNovel/{{Durarara}}'' has Episode 11. The leader and the founder of the Dollars is revealed.
** I'd argue that it's actually Episode 10. Even though the fact that [[spoiler: Mikado]] is the leader of the Dollars isn't explicitly stated until Episode 11, the end of Episode 10 ''strongly'' implies it. The [[WhamEpisode Wham]] comes from the realization that [[spoiler: this supposedly nice, innocent kid is actually a badass with a better handle on the situation than anyone else]] and that the seemingly inane details that fill the rest of the episode are not only important, but do a masterful job of setting up the end reveal. This was the episode that made the show go from "quite good" to "absolutely incredible."
** The person behind the Slasher attacks in episode 'Mutual love'.

* One episode of ''Anime/ExcelSaga'' does this and follows through with NothingIsTheSameAnymore. It'd be a good example of the latter trope too, but that gets twisted round in the last episode, titled ''Going Too Far'' for [[GettingCrapPastTheRadar a very good reason]].
** For those interested, Excel is the epitome of a GenkiGirl, and often is a SpannerInTheWorks for her idol, boss, and '''major''' crush Il Palazzo, who wants to conquer the city. [[AfterTheEnd After an alien invasion ends up destroying the town]], Excel gets lost and Il Palazzo begins his conquest of the city, ordering his men to kill her. She defeats all of the men, reaches his tower, and bangs on the door until her hands are bloody, asking just to see him again. He shows up and shoots her, then [[TearJerker leaves her to die in the sand]].

* Episode 25 of ''Anime/MagicalStageFancyLala'' where not only the title character loses the item to transform, but also loses Mogu and Pigu.
* In the very first one of ''Manga/FullmetalAlchemist'', the Generals of Central reveal to Mustang that they knew King Bradley was a Homunculus. They then disband Mustang's group forcing Fuery, Breda, and Falman to the borders of Amestris, and Riza Hawkeye becomes King Bradley's secretary, so that she can be used as a hostage.
** Gluttony almost kills Riza, the Mustang crew learns about Homunculi, Havoc's spinal cord is severed, Roy gets stabbed in the ribs, Al almost dies, [[TheStoic Riza]] learns Mustang "died" and starts screaming, crying, and has a HeroicBSOD, Mustang comes back and we learn that Homunculi actually can be killed. All in one episode.
** Pales in comparison to the meeting between the Elrics and Father. In the course of a chapter its revealed that Father is not Hohenheim (but he knows him), he can prevent anyone from using Amestris alchemy, but Xingese alkahestry can function. Scar finds out that the Homunculi started the Ishval War, and Ling is possessed by Greed. The next chapter reveals that Greed has no memories of his past life, and Ling is still in there.
** And Ed finding Al's body behind the Gate? Gosh dang.
** We also find out later that Hohenheim IS basically the Philosopher's Stone, as well as possibly the founder of modern Alchemy. Small wonder his kids are prodigies.
** The revelation of Pride's identity, ''just'' after the reveal that the entire country EXISTS TO BECOME A PHILOSOPHER'S STONE! Although this was more of a Wham because [[IKnewIt someone predicted it in advance]].
** And of course there's always the episode in Brotherhood where [[spoiler:Ed is impaled through his abdomen by a metal rod when Kimblee blows up the room. Meanwhile, Al feels his soul being ripped from his body]].
** Then in Chapter 104, Father reveals that his plan is to open the Gate of Truth for the planet. He also activates the country-wide transmutation circle, sucking out the souls of almost everyone in the country. Then he absorbs GOD into his body.
** In chapter 107, Al reverses the transmutation Ed did to attach his soul into the armor, returning Ed's right arm and getting trapped into the Doors of Truth in process.
** And let's not forget the [[Anime/FullmetalAlchemist 2003 anime adaptation]], such as when [[spoiler:[[TearJerker Hughes died]], or when it turned out that the Homonculi were behind the Ishvalan war, or the second to last episode. What, the other side of the gate is our real world? And you mean to tell me that alchemy is powered by the deaths of people in this world? (Meaning that part of the reason that all these plots are happening now is that Alchemy in general is being supercharged by all the deaths in World War I!) WHAT, Envy is really Hohenheim and Dante's son? HOLY CRAP did Ed just die?!]] Don't forget the reveal of Dante and Hohenheim's secret in Episode 45.
* ''Manga/ACertainScientificRailgun'' is a lighthearted show, till all of a sudden [[spoiler: Harumi]] of all people turns out to be a villain. That's surprising, but that's not the real wham. The real wham is when [[spoiler:some sort of bizarre creepy fetus thing comes out of her and lets out a inhuman roar.]] WTF moment for sure.
* ''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.
* ''Anime/{{Free}}'': Episode 5 of season 1. It goes from the status quo of pretty boys swimming to [[spoiler: one of the main characters ''nearly drowning'' in a matter of minutes.]]
* ''Manga/{{Fuuka}}'': Chapters 36/37. Fuuka, the title character, [[spoiler: gets hit by a truck and dies]].

* ''Anime/GaikingLegendOfDaikuMaryu'' episode 28... wherein SmugSnake and MagnificentBitch Proist singlehandedly delivers sucker punch after sucker punch to the protagonists, seemingly convinces a young girl to kill her own father, and just continues to make a living hell for everyone. With the exception of the whole "Limitation Syndrome" episodes, all those other light-hearted episodes seemed a lot more appropriate and necessary, with Proist rapidly become just as hated as [[Anime/MobileSuitGundam00 Fucking Ribbons]].
* ''Anime/GaoGaiGar'' Episode 31. The Zondar threat has been eliminated and the world is safe, right? WRONG! Enter the 31 Machine Primevals, who [[CurbstompBattle utterly decimate the Gutsy Geoid Guard base, and severely damage GaoGaiGar.]] What's more surprising than that? Pizza of the Four Machine Kings is revealed to be alive and has made a HeelFaceTurn! And then he [[CurbstompBattle easily takes down three Primevals with his own giant robot King J-Der!]] (Which launches from a ''volcano!'')
* The ''first three'' episodes of ''Anime/GaReiZero'' are WhamEpisode. First, the [[DecoyProtagonist supposedly-main-characters]] are killed in episode 1. Then, the bloody murderer in the episode before is introduced as a [[HeelFaceTurn lost member]] of another squad. And then, in the third episode ''flashback'' begun, which has nothing similar with the high body count of the first two episodes.
* The final "attack" of the Individual Eleven in the second season of ''Anime/GhostInTheShellStandAloneComplex''. Twelve terrorists join together to commit their greatest and final "attack", all of them bringing katanas with them. A police team is racing against time to stop them, when a news-helicopter spots them first on a skyscraper roof, broadcasting everything on live-TV. And without any warning they pull out their swords and decapitate each other!
* ''Anime/GiantRobo: The Day The Earth Stood Still'' episode 3, at very end. Daisaku and Giant Robo finally arrives at the battlefield, Daisaku gives a speech about how he can never forgive all the evil Professor Vogler did and orders Robo to attack Volger Sphere. But when Robo puches it....his arm ''breaks into the pieces''. [[spoiler: Also, next episode, in which several characters are KilledOffForReal]].
* ''Manga/GreatTeacherOnizuka'' had a veritable WHAM clusterfuck when Urumi posted a website showing video of Miyabi doing personal stuff around her house (she discovers hidden cameras in her bathroom and bedroom). Onizuka races to find Urumi before she kills herself while his students must find a way to shut the website down. Teshigawara convinces the vice-principal to kill Onizuka [[spoiler:but all that was a smoke screen so Teshigawara can kidnap Azusa]].
* Episodes 12 and 13 of ''Anime/GunXSword'', wherein Van catches up to the Claw, learns an unpleasant fact about Dann, and is forced to kill a close friend. Also revealed: Michael, Wendy's brother, now serves the Claw.
* ''Manga/{{Guyver}}'': There are a few, especially as it's a constantly-escalating plot, but the most infamous is when Sho's father becomes an unwitting Enzyme-type Zoanoid who rips the Guyver's brain out, forcing the Guyver to kill him on autopilot.
** The appearance of Archanfel, the {{Big Bad}} of the series, and the leader of the Zoalords. He gets sucked into a black hole, climbs out a couple of chapters later, and turns Guyver I and Guyver III's Mega Smashers back on them, nearly killing them in the process. As this takes the Guyver units out of the picture for a large chunk of time, the Zoanoids use the lack of any real threat to their powers to TakeOverTheWorld.

* ''Anime/HaibaneRenmei'' goes from peaceful SliceOfLife to TearJerker drama after chapter 6, when Kuu [[AscendToAHigherPlaneOfExistence takes the Haibane Flight]].
* ''Anime/HanaukyoMaidTai La Verite'' episode 7 "Unidentified Living Creature". Up to this point in the series the episodes had been light-hearted and comedic. An earthquake reveals a tunnel leading under the mansion. Deep underground the mansions there's a smaller duplicate mansion. Inside the duplicate mansion Chief Security maid Konoe Tsurugi finds on old portrait of a woman who looks exactly like Head Maid Mariel. This leads to a chain of events that result in Mariel falling deathly ill, being kidnapped by Taro's grandfather's minions and having to be rescued, all as part of the grandfather's plans.
* Episode 20 of ''Anime/HappinessChargePrettyCure'' finally reveals Hime's DarkSecret: [[spoiler:She's the one who opened up [[SealedEvilInACan the Axia Box]], unleashing [[BigBad the Phantom Empire]].]]
** Before that was Episode 13, which introduced [[TheDragon Phantom]], the self-styled "Pretty Cure Hunter" who has been defeating and ''capturing'' Pretty Cures like they were prizes.
* ''LightNovel/HaruhiSuzumiya'':
** Despite brief references to the supernatural, Haruhi appears to be an excessively {{Cloudcuckoolander}} who can't tell fantasy from reality... then comes episode five (chronologically third): Yuki, the girl who had just been sitting there reading when the club started, is an alien drawn to the planet by a cosmic disturbance three years before. Mikuru, whom Haruhi grabbed at random because she thought she was cute, is a time traveller there to understand the time travel threshold, three years before. Itsuki, who was inducted due to Haruhi's obsession with the idea of a mysterious NewTransferStudent, turns out to be from a group of espers who gained their powers in a cataclysm three years before. What are the odds? High, once you learn that Haruhi herself is a [[AGodAmI godlike being, unwittingly responsible for all three phenomena]]. And there are nine episodes to go.
** Technically the wham episode chronologically would have been Episode 4 (Broadcast Order Episode 10), where the ClassRepresentative traps Kyon in an artificial world and tries her best to kill him to see what Suzumiya will do, only to be stopped by the aforementioned Nagato Yuki, wielding reality-overwrite powers. And then he meets Mikuru's future self. This is around the point where Kyon realizes he ''has'' to believe all these weird outlandish stories.
* ''Anime/HeartcatchPrettyCure'' ''begins'' with a WhamEpisode two-parter. Cure Moonlight's defeat, Cure Blossom's introduction leading into a {{Cliffhanger}}... which is started off with her ''going into a mass panic''. This was ''not'' going to be a regular ''Pretty Cure'' series.
** Then you got Episode 10, which really puts the breaks on the fun when the Dark Precure shows up, hands Blossom and Marine their asses, then disappears.
* Episode 10 of ''LightNovel/HeavensMemoPad'' ends with [[spoiler:Ayaka's Suicidal leap of a the school building]].
* ''Anime/{{Heroman}}'' episode 4 was one, being the first time Joey and the eponymous robot couldn't do anything but stall, and one of those things was hard to stop, but at the end of the episode, ''more'' pop out, episode 5 established that the Skrugg aren't so stupid, and they promptly try to remove the threat with new, human soldiers (who turn out to be the JerkJock and his little buddy).
** Episode 13, Joey comes home from a date, his friends tell him that the government is after him, and he may have to leave, he does.
* In a very interesting variation, the ''Saikoroshi-hen'' arc in ''VisualNovel/HigurashiWhenTheyCry Rei'' was a mega WhamEpisode for ''VisualNovel/UminekoWhenTheyCry'', because before Rika returns to her original world that was post-''Matsuribayashi-hen'', she reveals that she is also [[VisualNovel/UminekoWhenTheyCry Frederica Bernkastel, the Witch of Miracles]]. After declaring that she would no longer hold that role, the two entities separated. In a nutshell, '''every''' Rika Furude (except the last one that survived) is Bernkastel. And they're bitter, hence we got ''End of The Golden Witch''.
** Higurashi itself has a few. For example, episode 25 [[spoiler: where you learn that the entire first arc was from an UnreliableNarrator's stand-point and he was [[MistakenForMurderer hallucinating]].]] The second season has numerous once we learn the plot, also one episode ends with [[spoiler:everyone dying, right after it looked promising that they would be safe]].
* Episode 10 of Hyperdimension Neptunia; while the rest of the show mixed things up a little, it essentially followed the plots of the second and third game. However in this episode when [[spoiler: Peashy is freed from Anonydeath's control]] instead of it and the following moments being heartwarming like in the game... you get a tearjerker of incredible proportions since [[spoiler: Peashy doesn't remember anything, unlike in H.N. Victory where she ends up glomping Neptune]]. The stark change to drama in what has almost always been a Comedy Anime, is a pretty big moment by itself; but the Tearjerker aspect when compared to the source material makes it have even more of an impact.

* Episode 13 of ''Manga/ICantUnderstandWhatMyHusbandIsSaying'' ends with [[spoiler: Kaoru's pregnancy test turning positive.]]

* Every episode in the second half of ''Anime/{{K}}'' counts as this, with revelations and twists coming one after another. However, special mention goes to Episode 6 and 11
** Episode 6: The majority of the episode is a flashback episode, explaining how Tatara Totsuka, the man that was murdered by the Colorless King, is related to HOMRA. The rest of the episode contains the major wham: [[spoiler: Shiro's memories are fake, meaning he really could be the Colorless King and just not remember it.]]
** Episode 11: [[spoiler: The Colorless King is revealed to be a {{Body Surf}}er, and is currently in the body of Kukuri, and Shiro is a King, the ''Silver'' King, Adolf K. Weismann.]]
** Episode 8 of the second season, ''Return of Kings'': [[spoiler: Iwafune, revealed in the previous episode to be the presumed dead Grey King, handily [[CurbStompBattle curb-stomps]] Reisi, and the ensuing damage to his resolve degrades his already cracking Sword of Damocles ''massively''. The Green Clan then make off with the Dresden Slate and Fushimi, frustrated with his boss, resigns from Scepter 4...[[FaceHeelTurn and joins JUNGLE]].]]
* Episode 42 of ''Manga/KamikazeKaitouJeanne'' has three revelations: The titular character has been an UnwittingPawn all along, her helper Finn is actually evil and serves the Devil, and Miyako ''finally'' discovers that the master chief she's been hunting throughout the show is none other than her best friend, Maron Kusakabe. [[TearJerker Ouch]].
* For its 7 first episodes, ''Manga/KannazukiNoMiko'' is cute, touching, sometimes silly, and full of FanService of all kinds, and if you don't sympathize with Chikane by the end of episode 7 you just have no heart (or don't like SchoolgirlLesbians for some reason). You MIGHT sense episode 8 is going to be a turning point, but you sure as hell don't expect Chikane to respond to Himeko's apparently choosing Souma by ''raping her'', stealing Souma's mecha and [[FaceHeelTurn becoming the 8th and most dangerous of the enemies]]. That is, [[AllThereIsToKnowABoutTheCryingGame if you're not watching the show for the twist]].
* ''VisualNovel/{{Kanon}}'' episode 21: [[spoiler: Akiko gets hit by a car.]]
* Chapter 12 of ''Manga/{{Karakuridouji Ultimo}}''. After introducing a whole bunch of new doji, in the previous chapter, new Evil Doji are introduced, who proceed to murder the Good Doji in brutal and disturbing ways, kill all the good doji members in almost as brutal ways. Then the world blows up killing anyone who had any ounce of life left. [[{{TheHero}} Yamato and Ultimo]] manage to use [[{{ResetButton}} Time Manipulation]] to save everyone at the last second, but, the fandom still probably suffers from that chapter.
** Chapter 21 in a different sense. Anybody who was uneasy about {{Yandere}}, [[{{StalkerWithACrush}} stalker]], and {{Depraved Homosexual}} Rune, proabably had a nervous breakdown when that chapter rolled around. Turns out Rune has no problem resorting to [[{{RapeAsDrama}} rape]] to get Yamato. It was only [[{{AttemptedRape}} attempted]] in the end, but still, it's not something that most people wanted in their head.
* Episode 6 of ''Literature/KemonoNoSoujaErin''.
* Chapter 466 of ''Manga/KenichiTheMightiestDisciple'': Kenichi and Miu, in escaping from Silcardo Junazard's base, are confronted by several master-class martial artists. It looks hopeless, as they're both worn down and out of energy...then suddenly John the mercenary, previously established as a buffoon, [[CrouchingMoronHiddenBadass shows up to rescue them, fending off the would-be killers]]! But that's not the Wham moment... [[spoiler:it's when, after a section of the burning room falls on John, his skin and clothes burn off--to reveal the tall, lean, muscular, serious form of [[PapaWolf Saiga]] [[MasterOfDisguise Furinji]], a.k.a. the "One Shadow" of Yami, a.k.a. ''[[BigDamnVillains the series]]' BigBad'']].
* Episode 15 of ''Anime/KiddyGrade'' ends with the destruction of GOTT headquarters, with the following episode introducing Eclair as acting chief of the "new and improved" GOTT... or so one would think.
* ''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 ''Anime/KokoroConnect'', [[spoiler: in episode 5, when Heartseed takes over Iori's body and jumps off the bridge]]
* Episode 20 of ''Anime/KurauPhantomMemory'' offers a major change in the premise of the series by introducing Rynax with evil plans to take over the world, who want to use Kurau for their purposes.

* ''Anime/LegendOfGalacticHeroes'' is very liberally sprinkled with this indeed, throughout its long run. This is to the point that every few episodes a Wham would happen. Here are some examples (the following list is NOT exhaustive):
** There are two well-remembered Whams. The first is [[spoiler: Episode 26: Farewell, the Old Days. The cliffhanger on Reinhard's assassination attempt is resolved most unexpectedly: His best friend and right-hand man, Siegfried Kircheis, dies protecting him. It's a significant Wham since, up to this point, Kircheis was one of the main characters]].
** The second one is, of course [[spoiler: Episode 82: The Magician Doesn't Return, a title which clearly spoils Yang Wen-Li's demise. Everything in the episode seems to be pointing towards a daring, last-minute rescue. That is, until the last minute, when the narrator makes it very clear that Yang has just bled to death. This is, again, unexpected and changes the entire dynamic of the show, since Yang was the driving force of one of the two main {{Cast Herd}}s]].
** There are many other Whams that are hugely significant to the show's various arcs. [[spoiler: The Kaiser's death to illness in season 1 robs Reinhard of one of his motivations and sparks a civil war in the Empire, which causes Reinhard to engineer a civil war in the Alliance, contributing to weakening the Alliance and enshrining his own position. In season 2, he then uses this to wage a campaign against the Alliance, occupying previously-neutral Phezzan, and closing the season with the unification of the galaxy under his rule, which cements his authority over the Empire. The Legend finishes, but the list goes on...]]
* In Chapter 16 of ''Manga/LetterBee'', 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.
* Episode 22 of ''Anime/LittleWitchAcademia'' basically turns the entire series on its head. [[spoiler: Shiny Chariot's magical show, the thing that made Akko want to be a witch in the first place, was also the reason why she is unable to perform magic properly. Chariot absorbed the magic potential from her muggle audience in order to use it as magical fuel to save the magic world, but this backfired and, for reasons yet unexplained, blew up the moon's surface. Chariot then wiped the audience's minds and assumed the identity of meek teacher Ursula to atone for what she'd done.]] If all that wasn't enough, [[spoiler: Croix is about to get a war started for the sole purpose of harvesting anger from the people and using it as magical fuel, basically repeating what Chariot did 10 years before, but with much harsher consequences.]]
* Subverted in ''Manga/LuckyStar'', with the heartwarming scene with the ghost of Kanata (which is a major swerve from the usual upbeat comedic tone of the series). After this scene? [[StatusQuoIsGod Back to the comedic status quo]].

* ''Anime/MacrossFrontier'' is laced with episodes that count as whams to some degree, almost to the point where you start to ''expect'' them later in the series.
** Episode 13: TheReveal of the BigBad.
** Episode 18: [[spoiler:A personal character wham. All glamour IdolSinger Sheryl Nome with a confidence the size of the sun is [[BreakTheCutie unceremoniously]] [[BreakTheHaughty crushed]]]].
** Episode 20: [[spoiler:AnyoneCanDie]].
** Episode 21: Ends on a character wham, [[spoiler:Ranka runs away from Frontier with Brera]].
** Episode 24: [[spoiler:Ranka singing ''for the enemy'' and Alto getting shot down in a ball of fire. Given the condition at the end of the episode, it really was looking like a KillThemAll, as practically the only good guy ''left'' is the terminally IllGirl]].
** Episode 25: The last episode, oddly. [[spoiler:EarnYourHappyEnding with ''prejudice''. Oh, and EveryoneLives]].
* ''Franchise/MagicalGirlLyricalNanoha'' does this surprisingly well if you think it's just a MagicalGirl series about nine-year-old girls.
** From the [[Anime/MagicalGirlLyricalNanoha original series]]:
*** Episode 4: Where Fate Testarossa appears and [[CurbStompBattle curb stomps]] Nanoha, taking the Jewel Seed and presenting Nanoha with her first major obstacle.
*** Episode 7: Nanoha and Fate's last fight has attracted the attention of the Time-Space Administration Bureau, introducing the wider setting. However, that's not the real wham. The real wham is Fate reporting in to her mother [[spoiler: only to be whipped for bringing ''only'' six Jewel Seeds.]]
*** Episode 11: Nanoha has finally defeated Fate, but Precia decides to go through with her plan without the complete set of Jewel Seeds. The TSAB manages to track down Precia's lair and sends a squadron in and discovers [[spoiler: a girl that looks exactly like Fate. This girl turns out to be Alicia, Precia's actual daughter. Fate is a failed clone that Precia only saw as a tool to help bring back the real Alicia. The revelation [[HeroicBSOD absolutely breaks Fate]].]]
** In ''[[Anime/MagicalGirlLyricalNanohaAs A's]]'' Episode 9, the protagonists accidentally encounter the Wolkenritter while visiting Hayate, and prepare to fight them. But then it turns out that the mysterious man who's been helping them is actually two people, and they absorb the Wolkenritter into the book and trick Hayate into thinking that Nanoha and Fate did it, causing the Book to awaken, possess Hayate and set out to kill the heroes.
** 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).
* ''Anime/MagicalProjectS'' is a hilarious parody of the magical girl genre and never takes it self too seriously. Until episode 19 where it's revealed to Sammy that her best friend, Misao, was Pixy Misa, the evil magical girl that tortured the main cast (Sammy included) with her magical powers, and she was about to harm her parents. Also, that Misao was in fact an StepfordSmiler and BeneathTheMask feels lonely, worthless and jealous of Sammy's happiness. [[NotBrainwashed Rather than the brainwashing]] the audience had been led to expect her evil alter ego was in fact really her all along (albeit her repressed feelings). The only thing Rumiya did was "unleashing" her hidden self. [[NiceJobFixingItVillain Nice job, Ramia]].
* The 7th episode of ''Anime/MagicalShoppingArcadeAbenobashi''. From a wonderful comedy to a heart-wrenching love drama...
** Even more so episode 9, which reveals the causes of the jumps.
* In the last episode of the first season of ''Manga/MagicKnightRayearth'', it turns out the Princess is the BigBad and ''not'' the DamselInDistress. TheDragon, Zagato, got killed trying to ''save'' her from death. The Princess' SuperpoweredEvilSide emerges and battles the girls. The PowerTrio has to kill her against their will and [[ICannotSelfTerminate under her pleas]], otherwise Cephiro dies. The Princess [[GoOutWithASmile dies smiling]] and sends the three broken kids back home. [[NiceJobBreakingItHero HOLY S...!]]
* The episode of ''Manga/SomedaysDreamersIISora'' with the reveal of Sora's terminal heart condition totally detonated the lightheartedness of the show.
* The ''Franchise/MaiHime'' SeriesFranchise has had several moments:
** The first "wham" comes at the end of episode 8 of the ''Anime/MaiHime'' anime, when Akane goes into an HeroicBSOD and has to be put into hiding after watching her boyfriend Kazuya die [[spoiler:when Miyu destroys her CHILD]], showing her (and the viewers) the true cost of protecting the ones you love. This one was immediately followed by a [[BreatherEpisode breather]] BeachEpisode, which still managed to sneak in a little plot and CharacterDevelopment unexpectedly.
*** However, an even ''bigger'' "wham" hits at the end of Episode 16. The heroines have defeated the invading [[NGOSuperpower Searrs army]], and decide to celebrate with a night of merriment and karaoke. Once done, they're all ready to go out and kick some more Orphan butt...except Nagi, who has isolated them from Mashiro and Fumi (who helped them fend off Searrs), tells them that the Orphans aren't coming anymore, and [[ThereCanBeOnlyOne forces them to fight against each other to ensure the world's survival.]]
** Episode 16 of ''Anime/MaiOtome'': The reconstruction of the portion of Mashiro's castle that was destroyed in an earlier episode is finally completed to coincide with Garderobe's graduation/advancement ceremony, and the large curtain is removed to reveal...[[spoiler:a Schwarz superweapon capable of summoning Slaves en masse to every corner of the planet]].
*** Then, in Episode 17, Schwarz invades Garderobe and holds the entire school prisoner, with Shizuru [[DeliberatelyDistressedDamsel offering herself as a hostage]] to allow Natsuki time to escape and seek help. Meanwhile, on the other side of campus, Nina has contracted herself to Nagi (the mastermind behind the whole takeover), who flips out and attacks [[TheHero Arika]] out of jealousy when she learns that [[spoiler:her adoptive father Sergey was Arika's MysteriousBenefactor, thus enabling her to attend Garderobe in the first place]]. And ''then'', [[spoiler:their friend Erstin is revealed to be a Schwarz sleeper agent, and is KilledOffForReal trying to stop the two of them from fighting.]]
** ''Manga/MaiHime'' manga: The chapter after Nagi's defeat and the subsequent victory parade. In comes the Searrs Institute for Girls [[spoiler:(led by Natsuki's mother, whom she believed to have been killed)]] to enact a hostile takeover of Fuuka Academy.
** ''Manga/MaiOtome'' manga: [[spoiler:Sergey killing Nagi]].
*** Then [[spoiler: the impostor turns out to be Mashiro's twin brother, making him a rightful heir to the throne.]]
* Episode 3 of ''Anime/MartianSuccessorNadesico'' announced to the viewers that this would ''not'' be a SuperRobot show where nobody really died by having Gai, the HotBlooded otaku, get shot and killed without ever seeing it coming.
** Also, episode 13: the heroes capture an enemy mech and it has a cockpit full of ''Anime/{{Gekiganger 3}}'' merchandise, thus proving that the "alien invaders" are actually humans.
** This extends into episode 16, where the history of the "alien invaders" is revealed.
* ''Anime/MazingerZ'': The final episode was an endless succession of shocking moments altered the status quo irremissibly: it was revealed that [[spoiler:Gorgon was actually working for someone was infinitely more powerful and most dangerous than Dr. Hell,]] Mazinger-Z was [[spoiler:utterly and easily defeated by a new enemy,]] a new and more powerful [[spoiler:Mazinger showed up, named ''Anime/GreatMazinger'']] and it was revealed [[spoiler:Kouji's father was alive.]] The Wham factor was even bigger in the movie version of that episode, when the Mykene army razed to ruins New York, London, Paris and Moscow in one single stroke before leading towards Tokyo and destroying it as well, and at the end of the movie, the prophet [[spoiler:removed his mask and revealed his real identity: Kenzo Kabuto, Kouji's father.]]
** Long before there was an episode where the villains took over a Japanese village in a very Nazi-like manner, including a systematic slaughter of the civilians that they considered "useless" and usage of the women of the village as human shields for their latest Mechanical Beast. That was quite shocking and brutal, too.
* ''Anime/MekakucityActors'': After Episode 5, the show [[CerebusSyndrome takes a dark turn]], and a Wham moment comes at least OncePerEpisode:
** Episode 6: Ene's past as [[spoiler:the very human Takane Enomoto]] is revealed, and her ties to Konoha, Ayano and Shintaro are explored.
** Episode 7: More on Ene's past, as well as [[spoiler:TheReveal that Kenjirou is the one that killed her and Haruka. We also get Azami's first appearance]].
** Episode 8: [[spoiler:[[BackFromTheDead The nature of the Dan's eye abilities]] is discussed, and Shintaro activates his [[PhotographicMemory power, remembering past timelines, and the meeting with Queen!Mary that gave him his power]]]].
** 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]]]].
** Episode 10: [[spoiler:We learn how Azami created the Daze, and that Shion and Mary's deaths on August 15th a century ago are why people are sucked in on that date]].
** Episode 11: [[spoiler:Kido, Momo and Hibiya are captured, Kano breaks down over memories of Ayano's suicide - which is [[SenselessSacrifice revealed to have been pointless]] - and Shintaro kills himself to enter the Daze and retrieve Ayano]].
** Episode 12: [[spoiler:The Wide-Open Eyes Snake possesses Konoha and manages to convince Mary to reset time, but Ayano and Shintaro arrive and prevent it, leading to the happy ending depicted in ''Summertime Record'']].
* ''Anime/MobileSuitGundam'' provides multiple examples. In fact, you can consider the first episode of TheOriginalSeries a meta-WhamEpisode for the entire anime industry, as it was the first RealRobot anime.
** Episode 40 of TheOriginalSeries ends with the Zeon firing the Solar Ray KillSat that destroys a third of the Federation fleet and kills both Zeon leader Degwin Zabi, and Federation Fleet commander General Revil. The real Wham? Earlier in the episode Amuro attacks Char, but Lalah Sune, [[LoveTriangle the woman both men loved]], [[TakingTheBullet intercepts the attack]] and dies. The result is that Char now hates Amuro for killing Lalah, while Amuro hates Char for letting Lalah fight. The rivalry ends in ''Char's Counterattack'' when both die during the battle.
*** Like anyone ''didn't'' see that coming, especially after the previous fates of Icelina, Hamon (Ranba Ral's girlfriend) and Miharu (the Zeon spy that Kai fell for). Doesn't help that Lalah was introduced only a few episodes back, yet held such a big impact on both Amuro and Char in her first appearance; that's practically a bright flashing neon sign that reads "DEAD GIRL WALKING!"
** ''[[Anime/MobileSuitZetaGundam Zeta Gundam]]'' is more of a string of wham episodes than anything else. Most notable are episode 3 where Kamille's impulsiveness causes the death of his mother Hilda while trying to save her. Then of course, we have the death of his star crossed girlfriend Four in episode 36 (again, at least partially caused by his recklessness) and episode 50 with one of the bleakest endings in all of anime.
** ''[[Anime/MobileSuitGundamZZ Gundam ZZ]]'' has several, including the episodes dealing with the ColonyDrop on Dublin are especially jarring when longtime Gundam survivor Hayato dies a classic, Tomino-esque pointless death. This means that Karaba's down the drain and the Argama and company are literally the last line of defense against Neo Zeon. The aftermath, including Puru's death, are no less shocking and this "unserious" installment in the franchise doesn't give us a BreatherEpisode until we get back in space.
** ''[[Anime/MobileFighterGGundam G Gundam]]'' has episode 14, which reveals that Domon's teacher, mentor and father figure Master Asia is working for the Devil Gundam and brainwashed 4 other pilots. It also introduces the rest of the Shuffle Alliance 4 pilots who are supposed to work together with Domon to protect the Earth. Episode 42 reveals that Doctor Mikamura, Rain's father, betrayed his best friend Domon's father by revealing to the Neo-Japanese government the Ultimate Gundam. It also reveals that the supposed BigBad is good, and is a brainwashed victim of the actual BigBad. Also, episode 40 is where we find out that Domon's mysterious BigBrotherMentor is a clone of said implied BigBad. There's also the fact that Master Asia is, unlike the Devil Gundam's other minions, NotBrainwashed. He joined its mission to [[KillAllHumans rid the Earth of humanity]] of his own free will.
** There are two in ''[[Anime/MobileSuitGundamSeed Gundam SEED]]'': the first is when TheHero is [[NoOneCouldSurviveThat apparently killed]] by his ForgottenChildhoodFriend and [[TheRival Rival]], triggering a chain of {{Heel Face Turn}}s that lasts for the rest of the series. The second is when the CoolShip's crew [[ConspiracyRedemption is betrayed by their own superiors and deserts]], instead opting to TakeAThirdOption and turn the war into a MeleeATrois.
** ''[[Anime/MobileSuitGundam00 Gundam 00]]'' basically pulled Wham Episodes rapid-fire since the Throne Gundams came out of the sky [[spoiler: and Nena blew up a certain wedding in Spain, totally wrecking the lives of Saji and Louise.]] Let's just say that fans spent at least two months screaming at their screens when ''yet another'' cliffhanger got thrown out there.
** And to not be less than the other series ''Anime/MobileSuitGundamAGE'' has episode 14. [[spoiler: Yurin L'Ciel, massive EnsembleDarkhorse and the most likely candidate to become Flit's girlfriend, is '''horribly''' killed off (as a homage to the original example above), which ultimately makes the traumatised Flit switch from MessianicArchetype to DarkMessiah.]]
* In ''Manga/MuhyoAndRoji'', the competition between Muhyo and Goryo concludes with [[spoiler:Goryo winning on a technicality, resulting in him winning control of Muhyo's office. Muhyo effectively puts Roji on leave, and tells him that he's fired if he doesn't learn what he has to do by the time they meet up again]].
* 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.
* ''LightNovel/MushokuTensei'' titles every one of its Wham Episodes as "Turning Point". Whatever happens in that chapter will have a massive impact on the story and also results in major reveals regarding preceding events.
** Turning Point 1: The main plot kicks off with the [[spoiler:Mana Calamity and the first meeting between Rudeus and Hitogami]]. At the same time many major players begin moving in response to the event.
** Turning Point 2: Rudeus first encounters [[spoiler:Orsted]] and after a lengthy battle [[spoiler:suffers a mortal wound only to be saved due to Nanahoshi]].
** Turning Point 3: Rudeus learns that [[spoiler:Sylphy is pregnant]] just as he receives a letter from [[spoiler:Gisu asking for help to save Zenith]]. Faced with contradicting advice from [[spoiler:Hitogami]], Rudeus chooses to [[spoiler:ignore Hitogami's advice for the first time]].
** Turning Point 4: Rudeus encounters [[spoiler:his future self who has come back to warn him about Hitogami's true plan and nature]].
* ''Manga/MyHeroAcademia''
** Chapter 13, which started like a regular lesson-of-the-day chapter, [[spoiler:only to turn into a life and death situation at the end, when the Villain Alliance revealed themselves to the students.]]
** Chapter 88: [[spoiler:All For One finally makes his move.]]
** Chapter 92: [[spoiler:All Might's true form is revealed to the world and Shigaraki is revealed to be the grandson of All Might's deceased mentor Shimura Nana.]]
** Chapter 161: Even though the mission was completed with success, left in two bittersweet notes. [[spoiler:Eri is quarantined due to her out-of-control quirk and fever so she won't be better or have full control of her quirk soon. Sir Nighteye, who Deku and Mirio went to for internship, died from his fatal injuries but not before seeing them changed their future and seeing All Might again one last time.]]
* In episode 8 of ''Manga/MyLoveStory'' it's revealed that Suna's father needs surgery on the same day as Yamato's birthday.
* ''Manga/MythicalDetectiveLokiRagnarok'', Episode 21. [[spoiler:Heimdall's death scene.]] Long story short: He trapped the main character and friends in an alternate dimension, eventually dragging the MC into a creepy platform strikingly reminiscent of the Great Bridge of Hylia. He then goes [[RoaringRampageOfRevenge completely unhinged]], exhausting very literally ''every ounce'' of his considerable power (which he had just gotten back from a certain thief) on the character he believed to be that thief -- the main character. Said character then deflects one of [[spoiler:Heimdall's]] attacks and uses it to kill his only friend in the entire series, a [[spoiler:falcon]], leaving an unholy mess of feathers to rain down upon [[spoiler:Heimdall]]. He goes totally off the deep end and winds up shattering at least 90% of the platform they had been previously standing on without even moving a muscle -- it just cracks under their feet. He then falls to his death with a truly cringe-inducing scream... and the normally stoic main character, after being returned to the real world, sheds a single tear. Keep in mind that this is coming from the same series which, a few episodes previous, was doing an ''Series/IronChef'' parody.

* The first few episodes of ''Anime/NadiaTheSecretOfBlueWater'' were pretty lighthearted. The two main characters were mostly running around, some Team Rocket-like jewel thieves were chasing them, and the titular Nadia was trying to find a way to get to Africa. Then they end up on Gargoyle's island and boy, things get REALLY dark out of nowhere. Most of the people on the island have been killed by Gargoyle's men. The main characters find a little girl whose parents and even dog were just killed, and it's a life or death situation when they all have to hide from them. It's truly scary.
* ''Manga/{{NEEDLESS}}'' begins as a ridiculous and humorous series...up until Episode 16, in which [[spoiler:Cruz is fatally injured and killed, as opposed to previous episodes in which his injuries were always played for laughs]].
* ''Anime/NeonGenesisEvangelion'' has several towards the end:
** Episode 18: Evangelion Unit-03 is taken over by the angel Bardiel, but Shinji refuses to fight it because he doesn't want to risk harming the pilot. Gendo responds by activating the Dummy System for the first time, leading Unit-01 to tear Unit-03 to shreds. As a result, the pilot of Unit-03, [[spoiler:who is revealed to be Toji]], is mortally injured and gets [[PutOnABus hospitalized]] for the remainder of the series ([[spoiler:he dies in the manga]]).
** Episode 19: During the fight against Zeruel, Unit-01 goes berserk, steals one of Zeruel's arms for itself, and '''eats''' the angel, including its S2 engine. Unit-01 then breaks free of its armor, which Ritsuko reveals is actually a type of restraint meant to control Unit-01's power, and reveals organic tissue underneath. In other words, we get definite proof that Unit-01 is '''alive'''.
** Episode 20: We learn that because Unit-01 ate Zeruel's S2 engine, it has achieved the status of a [[PhysicalGod living god]], and get a final confirmation that Shinji's mother is the soul of Unit-01.
** Episode 21 is the point where the show gets DarkerAndEdgier by [[spoiler:killing off Kaji]] just after the TheReveal that NERV [[spoiler:is holding Lilith, not Adam, inside Terminal Dogma]].
** Episode 22: In one of the most [[NauseaFuel traumatic]] and terrifying moments of the franchise, [[JerkassWoobie Asuka]] is [[MindRape Mind Raped]] into a coma, while revealing a backstory that is even darker and more traumatic than Shinji's or Rei's.
** Episode 23: During the battle with Armisael, [[TearJerker/NeonGenesisEvangelion Rei sacrifices herself to save Shinji]]. But no worry, [[spoiler:clones of her are being prepared in the deepest levels of the NERV facility... Sorry, ''were'' being prepared. Ritsuko destroys the tank after Gendo sent her to SEELE answer for Rei's recovery]].
** Episode 24: After running away, again, NERV agents finally find Asuka, alive, [[spoiler:in a bathtub full of blood after a suicide attempt by slitting her wrists]]. Kaworu Nagisa, The replacement for Unit-02 arrives, and befriends Shinji instantly. [[spoiler:Too bad he's the final angel. Kaworu eventually convinces Shinji to kill him]], sending the poor kid into a crippling depression.
** 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]].

* The end of Volume 10 of ''Manga/{{Ooku}}: The Inner Chambers'' ends with the realization that with Harusada abdicating her claim to the shogunate, the only candidate left to inherit the throne after Ieharu's death [[spoiler: is a ''man'']].
** The end of Volume 12 qualifies too: the vaccine for the Redface Pox is a rousing success and the male population is slowly rising...[[spoiler:just in time for Commodore Perry to show up to force Japan to end its isolationism.]]

* Pop up often enough in ''Manga/PandoraHearts'' to warrant its own page, with Retrace 65 being the most infamous for crushing the status quo of the series thus far.
** After that came some chapters that served as [[MindScrewdriver Mind Screwdrivers]], then came Retrace 70...
* ''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.
** More like Episode 13. After the {{big bad}} is defeated, Stocking casually wonders if [[spoiler: angel weapons work on angels. She then proceeds to kill Panty by slicing her into 666 pieces, in order to resurrect the {{Big Bad}}, say "I'm actually a demon", and then walks off into the distance with the aforementioned {{big bad}}]].
* ''Anime/PlasticMemories'': After the first four episodes help establish the characters, Episode 5 takes a dark turn in revealing what happens when an expired Giftia becomes a Wanderer, or a machine driven only by basic programming. Moreover, the episode sees the introduction of R-Security, an anti-Wanderer PMC group that was responsible for [[spoiler:killing Michiru's Giftia father]].
* Despite being based on an earlier work, ''Manga/{{Pluto}}'' has a few:
** [[Manga/AstroBoy Atom]] dies in a fight against Pluto.
** In a flashback Gesicht hounds a human being into a corner and murders him, overcoming his in-built robotic rules through sheer hatred.
** Gesicht, the main character, is murdered three-quarters of the way through.
** Brau 1589, the resident psychopath and [[Literature/TheSilenceOfTheLambs Hannibal Lecter]] expy, spares the Thracian president and sacrifices himself to kill the real mastermind ''on the very last page''.
* ''Anime/{{Pokemon}}'' has a few:
** EP-015 "Battle Aboard the St. Anne". Giovanni appears for the first time and orders Team Rocket to attack the St. Anne and at the end the ship sinks with the group on board.
** 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.
** EP-134 "Charizard's Burning Ambitions". Ash leaves Charizard, one of the anime's most loved Pokemon on the Charricific Valley.
** AG-044 "The Princess and the Togepi" and AG-045 "A Togepi Mirage". Misty comes back, is revealed to own a Gyarados (depends if you are watching Chronicles on their Japanese air date), her Togepi evolves, and it's then released to take care of the Togepi paradise.
** AG-132 "The Scheme Team". [[spoiler:Ash encounters Agatha, who is the Viridian Gym Leader here and battles her. Then finds out about the battle Frontier and decides to challenge it.]]
** DP-050 "Tag, We're It", 051 "Glory Blaze", and 052 "Smells Like Team Spirit" form a three-part WhamEpisode. [[TheRival Paul]], who's already established to be excessively harsh on his Pokémon, abandons Chimchar mid-battle for being too weak, prompting [[AllLovingHero Ash]] to pick up the slack and adopt Chimmy. Not only does this drive home the radical differences between their philosophies, it also lays the groundwork for their Sinnoh League battle in which [[spoiler:Ash defeats Paul with the aforementioned Chimchar, having evolved it into a powerful Infernape]].
** DP-189 "The Semi-Final Frontier". [[spoiler:Ash gets to the Sinnoh League semifinals, where he finds a strong trainer named Tobias. After many losses Ash gets to beat his Darkrai, but Tobias is then revelated to own a Latios who ends up at a tie with Ash's Pikachu, leaving Ash with no Pokémon left and thus eliminated from the League.]]
** BW-016 "Rematch At The Nacrene Gym!" While not exceptionally noteworthy plot-wise (though Ash does collect a Gym badge), this is the first episode since the actual pilot to experiment with a story not involving Team Rocket in any way whatsoever. From this point, Team Rocket are demoted to recurring characters instead of full time appearances, with several episodes after breaking the original formula to focus solely on the exploits of the heroes.
** BW-018 "Sewaddle and Burgh in Pinwheel Forest!" Ash captures [[spoiler:Sewaddle]], breaking the format of Ash capturing only six Pokemon per Region. Ash would go on to catch [[spoiler:nine]] Unova Pokémon.
** XY-060 "A Showcase Debut". Serena participates on her first Pokemon Showcase, but [[spoiler:loses in the Theme Performance round. Early the next morning, Serena goes to a dock and cries for her failure, but after being reconfortated by her Pokemon, she proceeds to cut her hair and change her style permanently.]] Additionaly, a mysterious woman and a former performer named Palermo is introduced.
** XY-062 "The Future Is Now, Thanks to Determination!" [[spoiler:Clemont decides to leave the group temporarily in order to prepare his battle with Ash. This is the first instance of a travel companion leaving the group in the middle of a series, though Clemont comes back after said battle.]]
** XY-064 "Battling with Elegance and a Big Smile!" [[spoiler:Serena meets her idol Aria (disguised as Ariana) and gets to battle her, with her Fennekin evolving into Braixen in the process.]]
* ''Manga/PokemonDiamondAndPearlAdventure'' has a few such as [[spoiler:when it's revealed that Mitsumi is an ex-member of Team Galactic]] or where we meet Hareta's father.
* ''Manga/PokemonAdventures'':
** 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.]]
** And now the ending of the same Arc drove the fans to massive crying [[spoiler:as Black is sealed away with the Reshiram in the lightstone, White tries to take it but it flies away, she breaks down and let out a desperate cry for him to return]] this is specially tragic because, one chapter before, Gigi returned to her.
** 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.]]
* The anime version of ''Manga/{{Pretear}}'' has a WHAM episode in Episode 10 when Sasame--the [[TheChick sweet, sensitive]] member of the group--suddenly reveals he's in love with the DarkMagicalGirl and pulls a FaceHeelTurn.

* ''Anime/QueenMillennia'': A dozen or so episodes in it is revealed that the leader of the terrorist group attacking the main characters is in fact [[spoiler:Yayoi's sister, the original choice for the Millennial Queen]], and that [[spoiler:she did a FaceHeelTurn to the humans' side. Which Yayoi is NOT on.]] Yayoi then does [[spoiler:a FaceHeelTurn of her own against her mother and sides with the thieves]]. This changes how ALL the factions in the series were seen until then.

* ''Manga/RideBack'': Though the show is clear that it's a dark take on things, Rin's friend, Suzuri, is the one keeping the show as light as it is. She's showing off having fun when the government decides that Rin is to be considered a terrorist and needs to be stopped. They decide that the one showing off is the terrorist. It doesn't help that the preview for the next episode focuses on Suzuri acting like herself.
* Episode 34 of ''Anime/RevolutionaryGirlUtena'', in which two meta characters interact with the main cast for the first time in the entire series, and in doing so casually reveal the entire plot and (almost) all of its secrets. Suddenly, everything that's happened up til then makes sense, and it's ''horrifying''.
** Not to mention episode 33, which features [[spoiler: Utena]] having sex with Akio. In a clip show.
** You're all forgetting the original WHAM episode - episode 23, wherein we learn huge chunks of Mikage's memories are fake. [[spoiler:Nemuro burned down the hall, the real Mamiya died years ago, and Anthy was posing as Mamiya the whole time.]]
* ''Manga/RosarioToVampire'' has Chapter 9, "Secret". The main cast other than Moka (who knew all along) learn that Tsukune is human, as does the ArcVillain Kuyou. The next chapter continues the wham by having Tsukune almost die and have to be given vampire blood to live, Inner Moka--up until then an archetypal InvincibleHero--getting her ass kicked and ''Tsukune'' stopping the bad guy.

* The ''Anime/SailorMoon'' anime has ''various'' Wham Episodes;
** The first WhamEpisode in the series is probably the one where [[spoiler:Nephrite dies]]. Before that, it was mostly about the wacky adventures of three clumsy superheroes and their talking cat; this episode marks the first time someone other than a MonsterOfTheWeek actually dies (as opposed to being [[HumanPopsicle frozen in a crystal]]), leaving another character heartbroken, and things generally take a darker turn from here.
** After that, the reveal of the Moon Princess and the Legendary Silver Crystal (at the same time, no less), not to mention the revelation of Usagi's identity to Mamoru followed by his to Usagi and later the others. While her identity was quite obvious from the beginning, especially in the original North American dub where it was shown in the ''first episode'', the scene where it finally happens is genuinely shocking and touching.
** Also, in the next season, when Chibi-Usa is revealed to be Sailor Moon and Tuxedo Kamen's daughter, and by association, later, that Sailor Moon and Tuxedo Kamen are going to be King and Queen of Crystal Tokyo.
** Another Wham in the following episode: the revelation that the dragon Sailor Moon was forced to destroy was actually [[spoiler:Esmeraude]], and that doing so condemned [[spoiler:her]] to the void. It was ''here'' that everyone began to think there was more to the Black Moon Clan than just evil intent. A couple episodes later, [[spoiler:Saphir]] confirms the hunch by revealing that (1) they have feelings, too, and (2) [[spoiler:[[GreaterScopeVillain Wiseman]] [[ManipulativeBastard is manipulating them]] and is the real enemy]].
** Chibi-Usa's new friend Hotaru, the IllGirl with the healing powers? At the end of the same episode, her dad is revealed to be ''the season's BigBad''.[[note]]It's pretty neatly done, too. Hotaru never revealed her last name, and when we see her dad for the first time, the only weird thing about him is a pattern on one of his eyeglass lenses. It's only once they're back inside and he returns to his lab that his face becomes ScaryShinyGlasses again and we indirectly learn Hotaru's last name: ''Tomoe''[[/note]]
* ''Anime/SamuraiFlamenco'' is an exercise in SerialEscalation, starting in episode 7 when [[spoiler: a drug addict transforms into a giant gorilla with a guillotine in its stomach and kills several police officers.]] Then again in episode 11, episode 18, and episode 19.[[HolyShitQuotient Oh yeah. Its that kind of anime.]]
* ''Manga/SchoolLive'' is chock full of these, given its UnreliableNarrator approach to telling a story, and then showing the viewer that it was shown horribly, horribly wrong.
** Episode/Chapter one: So this is a {{Iyashikei}} SliceOfLife comedy about a few girls who live at their school, right? It looks like it is... until we see a shot that ''isn't'' from Yuki's perspective, revealing [[ThroughTheEyesOfMadness nearly all of what was shown took place in her head]], and that in reality, something very ''very'' bad is going on.
** Episode six [[spoiler:reveals without a doubt that Megu-nee was DeadAllAlong and that every time we've seen her outside of flashback was actually just a part of Yuki's delusions.]]
** Episode eight [[spoiler:has the girls find an emergency manual, and they learn the government knew of the possibility of a zombie outbreak, and that it may have been the result of an experimental biological weapon. Exactly why such a weapon was being developed is as of yet unknown.]]
** Episode ten [[spoiler:shows that the zombified Megu-nee infected Taroumaru, and then she bites Kurumi as well. Miki tries to find an antidote promised by the emergency manual, but as she prepares to do so, the zombies break down the barricades keeping them outside, making their way into the school.]]
*** The manga has many of its own as well.
** Chapter 5: [[spoiler:Megu-nee has been DeadAllAlong and the current Megu-nee we see is actually Yuki's imagination.]]
** Chapter 15: [[spoiler:According to Miki, Yuki might be faking her delusions.]]
** Chapter 18: [[spoiler:The school was given a Government Emergency Manual on how to deal with the zombie outbreak, revealing the government knew about the zombies beforehand. Also Kurumi gets infected after she was attacked by a zombified Megu-nee!]]
** Chapter 20: [[spoiler:Rii-san holds a knife, ready to strike Kurumi, who seems to be on the verge of turning into a zombie. Until Miki returns with the medicine to delay the zombification process.]]
** Chapter 22: [[spoiler:The government did know and the school had some sort of contract involving it. The reason for Megu-nee being in the shelter was not due to trying to get medicine for herself; ''[[ItCanThink She briefly regained her humanity]]'' while tearing at a door with other zombies and thought to try to retrieve the supplies for the girls before going feral again. Someone else had also opened up the shelter before she got there.]]
** Chapter 25: [[spoiler:A search party on a military chopper arrives over the area the school is in. However, we are shown the reaction of the soldier within, and the implication is that Kurumi isn't out of the woods yet, and will likely have to take the serum to stave off the effects of the infection for the rest of her life, ala VideoGame/DeadRising... except the cache at the school has less than five doses of serum left.]]
** Chapter 26: [[spoiler:The search helicopter crashes in the school grounds. Kurumi and Miki go to see if there are survivors, but once they get there, Miki is convinced that there are none. Before the two are able to turn back though, the fuel leaking from the helicopter catches fire, which then causes a massive explosion that catches both girls in the blast. And as they lay stunned, burning figures can now be seen shambling out of the wreckage...]]
** Chapter 32: [[spoiler:The group arrives too late at the home of the person transmitting the radio broadcast, and it is implied that Kurumi had to put the person out of her misery.]]
** Chapter 33: [[spoiler:Kurumi discovers that normal zombies now ignore her, and will only attack her if she makes a racket. This, and her ice-cold temperature, leads Miki to believe that the serum they used failed, and that Kurumi is in a ''really'' awkward situation right now.]]
** Chapter 35: [[spoiler:Rii loses it, and sneaks out one night to try and find her sister in a zombie-infested kindergarten. While she returns safely at the end of the chapter with a little girl with her, the odd looks Miki and Kurumi give each other point to something ''very'' amiss. It's worth noting that the tie the little girl wears looks very much like the moustache of a certain teddy bear, and in the last panel she even seems to have bear ears on her head...]]
** Chapter 36: [[spoiler:The girls run into other survivors for the first time in a long while. However, it begs to be seen if they're really as nice as they introduce themselves to be...]]
** Chapter 38: The girls encounter a much friendlier group of survivors. Like at their high school, the new survivor hideout has power, reserves of food, and much to Kurumi's delight, video games.
* ''Manga/SchoolRumble'' had Eri then Yakumo introduced as potential love interests for Harima. The manga showed Karasuma admitting he really is in love with Tenma [[spoiler:and he has a terminal disease]].
* Sekai de Ichiban Tsuyoku Naritai: [[MaskedLuchador Blue Panther]], thought to be, for 2 episodes, [[CoolMentor Misaki]]'s rival Juri, [[spoiler: was in fact revealed to be a rival, yes...but [[TheHero Sakura]]'s rival, Elena.]]
* In ''Manga/SekaiichiHatsukoi'', episode 16 is what shocks the viewer given that this [[MoodWhiplash series is a light hearted shonen ai comedy with some drama.]] The ending of the episode leaves a bitter taste in your mouth.
** To sum up the episode, Chiaki thinks that Hatori is cheating on him with his ex-girlfriend in high school and that he deliberately skipped out on their date to see a movie (which was staying in theaters for one last day) in order to see her. Pissed off and jealous, he goes to Yanase's house to vent. The typical drama of this series. [[spoiler: Then things take a turn for the worse when Hatori calls Yanase and Yanase says he's not handing Chiaki over. Yanase tries to confess to Chiaki a second time hoping he would take him seriously this time (and at this point, Yanase is desperate for Chiaki to return his feelings). By forcing himself on Chiaki, Chiaki retaliates by actually punching in the face (and mind you that Chiaki is the type of person that wouldn't hurt a fly) and the rejection finally causes him to [[BreaktheCutie break down]] [[CryCute crying]] in front of his best friend. Naturally, what makes the situation worse is Hatori forcing his way inside the house and [[KickThemWhileTheyAreDown proceeding to beat up]] Yanase after he [[HeroicBSOD literally shut down and wasn't going to fight back.]] Chiaki stops Hatori in time and Chiaki literally treats Yuu the same as always as leaving,]] which leaves a bad aftertaste considering the fact that the episode ends with Hatori explaining why he was with his ex girlfriend in the first place and Chiaki forgetting what happened. A what the hell moment with Chiaki acting like nothing happened? Sure. A KarmaHoudini for Hatori in this episode? Definitely. [[TheChewToy Yanase is just that unlucky.]]
* ''Anime/ShinMazinger'' had a Wham Ending. [[spoiler: In the final episode, Kouji finally defeats and kills Doctor Hell. The same moment sky goes red, the victorious music suddenly stops and weird things start coming from the sky. It's then revealed that Doctor Hell had installed a program in Baron Ashura that prevented him from comitting suicide as long as Hell is alive. Now, after tricking Kouji into killing Hell for him, Ashura takes his own life, breaking the ancient seal and unleashing [[GreaterScopeVillain Mycean Empire]], lead by Great General Of Darkness, on the world]].
* Easily half the episodes of ''Anime/{{Simoun}}'' count, but for some highlights:
** Episode 8: [[spoiler:Anglas, the Plumbish priestess Chor Tempest is hosting, is a suicide bomber that destroys over half the Simoun fleet and the anchor ship ''Arcus Prima''.]]
** Episode 14: Dominura convinces Wapourif to dismantle the Simoun's helical motors. [[spoiler:It's unclear what she sees, but it leaves her shaken to her core.]]
** Episode 16: [[spoiler: Rimone and Dominura perform the Emerald Ri Maajon and disappear.]]
** Episode 17: [[spoiler: Anglas's body is discovered inside an ancient Simoun, and Plumbum has gotten their hands on a couple Simoun.]]
** Episode 19: [[spoiler: Mamina sacrifices herself to keep the Plumbish priestesses from being executed as traitors for letting Neviril escape.]]
** Episode 21: The real purpose of the Emerald Ri Maajon is revealed. [[spoiler:It allows someone to travel back in time, and Neviril and Aer are ordered to perform the Emerald Ri Maajon to stop the war from happening in the first place. Rimone and Dominura are also revealed to be alive in the distant past, before the Simouns became a way of life. Dominura reveals that what she saw in the helical motors was her coming back to this time to found the Simoun tradition in the first place, and therefore be indirectly responsible for the war. She and Rimone decide to let it happen anyway, as the Simoun tradition was how they met in the first place.]]
** Episode 23: Simulacrum realizes they can't win the war and surrenders.
** Episode 25: The occupation forces learn that Aer and Neviril haven't chosen a gender yet, and arrest the pair, planning to take them to the Spring by force. [[spoiler:The now former members of Chor Tempest, their former commanding officers, and Plumbish priestesses break them out, giving them a Simoun so Aer and Neviril can perform the Emerald Ri Maajon.]]
* Sket Dance, 'Switch Off'. [[spoiler: Kazuyoshi Usui became 'Switch' in memory of his late younger brother, who was murdered in confused circumstances Switch blamed himself for. Done in the form of a [[WhamLine Tomato]] [[TomatoSurprise Surprise]] with the proceeding episode - Takemitsu reconciling with his younger brother, and Switch's reaction to it - going some way to mislead viewers about what happens.]]
** 'Ogress'. [[spoiler: Himeko's backstory.]]
** 'Happy Birthday' and 'Happy Rebirthday'. [[spoiler: Bossun's backstory.]]
** 'Switch On'. [[spoiler: How Switch meets Bossun and Himeko.]]
* ''LightNovel/{{Slayers}}'' is usually free of these, being more comedy-oriented. One notable exception occurs towards the end of ''Slayers Next'', when Gaav [[NoSell survives Lina's Ragna Blade]], then Fibrizo reveals himself and effortlessly kills Gaav. It's striking because up to this point Gaav had been clearly presented as the antagonist and Fibrizo does not appear in the opening credits (OK, he does, but you only realize this after TheReveal is pulled off). The series' tone shifts entirely after this episode as the humor is toned down and characterization kicks into full speed.
* Episode 10 of ''Manga/{{Sola}}'' is this, when [[spoiler:Matsuri reveals to Yorito that he's not a human, but rather a golem made of paper that Aono had made with her yaka powers and implanted with the memories of her dead brother, Yorito]].
* People were wondering if [[WarIsHell war]] would ever be shown in ''Anime/SoundOfTheSky'', being a military show. It is, in Episode 7, and changes the view on one of the characters [[HiddenDepths completely]].
* ''Manga/SoulEater'': The episode where the [[spoiler: Kishin is revived]] You ''know'' that this is a wham episode too, because after this arc ends and the new arc begins, you start to see less and less comedic fillers and more exhausting and '''''BRUTAL''''' battles in the series.
** Chapter 87 [[spoiler:Chrona kills Medusa]]. And in chapter 88 it ends with [[spoiler:Shinigami's WhamLine ordering Spartoi to kill Chrona]]
** Chapter 110 [[spoiler: Kid gains his father's power, Shinigami-sama dies and on the very last page, the Kishin stabs Maka straight through her chest]]
** Chapter 112 [[spoiler: Crona attempts to become a Barrier Maiden to seal Asura...and the resulting wave of black blood either kills or traps [[BumblingDad Spirit]], [[TeamMom Marie]] and Sid.]]
* ''Anime/StellviaOfTheUniverse'' where in episode 11, [[spoiler:Ayaka attacks Shima out of jealousy for her achievements]], and episode 16, [[spoiler:where people actually die, for the first time]].
* ''Anime/StrainStrategicArmoredInfantry'' is another series where the first wham comes at the end of the first episode: Characters are introduced, and even hints of a romance is set up... Then the brother of our main character shows up and [[KillEmAll kills everyone]].
* ''LightNovel/SundayWithoutGod'': In episode three, [[spoiler:the immortal character is KilledOffForReal after his wish for a "happy death" comes true, setting up one of the series' main themes of BeCarefulWhatYouWishFor.]]
* The attack of the Bodolzaa fleet -- and its outcome -- in ''Anime/SuperDimensionFortressMacross''. Given how every other television show went during its time, NOBODY expected 90% of the Earth's surface to be reduced to ash.
* The first half of ''Anime/TamakoMarket'' is a plain--if not downright boring--SliceOfLife. Then in episode 7 Choi arrives and chews out [[TalkingBird Dela]] for neglecting his duties. After a few misunderstandings (mostly the result of Dela trying to shift the blame for his idleness), she comes to befriend Tamako. At the end, she recognizes Tamako as her prince's destined bride.[[spoiler:She is wrong, however.]]

* ''Anime/TenchiMuyo'' gets one in OAV 3, Episode 6. After spending the past five episodes setting off conflicts and sitting back to watch, Zetto decides to take direct action against Tenchi, by '''BLOWING UP HALF OF EARTH.''' And I don't just mean half the surface, I mean all the way down to the core and back out the other side. And just to cap it off, after giving Tenchi a cheery "Yo", he waves his hand and ''vaporizes most of the moon''. This later reveals a slightly subverted Wham when Tenchi manifests himself as a god.
** Before this, there was two in OAV 2. In episode 1, we learn about Washu's past and that the form we see her in ISN'T her true form. And episode 2, we find out Sasami's past.
* ''Anime/TengenToppaGurrenLagann'':
** ''Episode.'' ''Eight.'' So you thought this series was just a fun, episodic romp, mmm? Well, here, the PlotArmor comes off, manly tears are shed, and HeroicBSOD ensues. From here on out, the show takes itself much more seriously, and so does the audience.
** Near the end of episode 15, just when it seems like [[DiscOneFinalBoss the Spiral King]] is defeated and the main conflict is over with, he gives a rather ominous warning about a million people reaching the surface of the planet before he dies. This is the show's first clear sign of its ''true'' BigBad, the Anti-Spirals.
** Episode 26. The fuel for the world and everything our heroes have been fighting for may eventually, should it continue to grow, kill absolutely everything in existence. And you thought the [[AntiVillain Anti-Spirals]] were just sociopaths.
* The 10th of ''Anime/TigerAndBunny'' ends with the long-awaited arrival of [[spoiler:the Ouroboros organization, which introduces itself by taking the ''entire city'' hostage for the release of their leader]]. Episode 10 is ''then'' entirely dwarfed by the events of episode 12, where [[spoiler:Kotetsu accidentally betrays the trust Barnaby was slowly developing in him... Right before Jake utterly ''destroys'' Kotetsu in a one-on-one match, sending him to the ICU in critical condition while Barnaby awaits his own fight with Jake]]. The fandom collectively suffered a massive nervous breakdown as soon as the credits rolled.
** And now there's episode 16, which reveals that [[spoiler:Kotetsu's longtime hero, Mr. Legend, was Yuri Petrov's father -- Yuri Petrov's ''abusive'' father]].
** Every episode from 19 onward is a combination of this and FromBadToWorse. Observe:
*** Episode 19: [[spoiler: It turns out that Maverick is the one who actually murdered Barnaby's parents. He tells this to Barnaby - right before wiping his memory with heretofore unknown NEXT power.]]
*** Episode 20: [[spoiler: Maverick wipes the memories of most of the other heroes. Kotetsu is officially [[{{Unperson}} Unpersoned,]] blamed for the murder of Samantha, and the other heroes begin to hunt him down.]]
*** Episode 21: [[spoiler: As Kotetsu is running for his life from his friends and co-workers, ''Lunatic'' of all people swoops in to save his life.]]
*** Episode 22: [[spoiler: Kaede shows up as LittleMissBadass and cures the heroes of their amnesia...except for Barnaby, who ends up facing Kotetsu one-on-one.]]
*** Episode 23: [[spoiler: Just as Barnaby remembers who Kotetsu is, it's revealed that the other heroes have been captured and hooked up to bomb collars a la Battle Royale]]
*** Episode 24: [[spoiler: Kotetsu dies...]]
*** Episode 25: [[spoiler: ... temporarily. He comes back to punch Maverick in the face. Unlike the [[TearJerker sad]] or terrifying whams above, this one is awesome. There's also the fact that he finally decides to quit being a hero... [[TenMinuteRetirement for all of six months.]]]]
* ''Manga/{{Trigun}}'' has five.
** Episode 12 contains the series' now iconic bout of CerebusSyndrome.
** Episode 16: We get to see first hand how Vash blew up July city.
** Episode 17: WholeEpisodeFlashback revealing Vash's history and nature.
** Episode 23: The death of [[spoiler: Nicholas D. Wolfwood]].
** Episode 24: Legato forces Vash to [[spoiler:kill him]].
** Every episode from 20 to 24 has an increasing magnitude of Wham.
** The manga also has one at the end of the original's run, where Vash meets up with Knives. The results are similar to that of episode 17 of the anime.
*** Vol. 6 of ''Maximum'' has a giant wham moment at the end. So, you know how Vash's hair is slightly blacker than it was in the original series? [[spoiler: Turns out that it represents a Plant's lifespan and their hair darkens each time they use their powers. ''Every time Vash uses his skills he's been slowly killing himself''.]]
* ''LightNovel/TokyoRavens'' has the [[HeroicSacrifice death of Natsume]] at the end of episode 20.
* ''Manga/TsubasaReservoirChronicle'' exemplifies this in Acid Tokyo when we find out that [[spoiler:Syaoran was really a clone of the original the whole time, and he proceeds to eat Fai's eye and have a big epic battle with his original counterpart]]. Then [[spoiler:Kurogane]] gets Yuuko to turn [[spoiler:Fai into a vampire]] so he can survive, and in return he is the only person [[spoiler:Fai can feed on]] ({{Ho Yay}} anyone?) After that we find out that [[spoiler:Sakura was also a clone, and then there's the whole "WTF" moment when we find out... Syaoran's his own father? And Sakura's... His mother? And Yuuko... Was actually dead the whole time]], and Buttchin is trying to keep her alive?
** Pretty much everything during and after the country of Recort. Kurogane's past, Acid Tokyo, Infinity and Fai's past are all very VERY much WHAM. Especially Fai. Go on and read his past, then reread the manga. That smile just doesn't seem the same anymore.
* ''Manga/TwentiethCenturyBoys'' uses this in full force when [[spoiler:the BigBad]] is murdered. Halfway through the series. As an extra jab they [[spoiler:reveal his identity]] right after.
** Urasawa had already done it once before, at the end of volume 5 when we learn that Kenji completely failed and the BigBad controls Japan. He does it again at the end of volume 15 when we learn they now controls the whole world and the calendar now dates from his resurrection. Yeah, that's right: the BigBad ''replaces Jesus!''
** That part has another piece of wham immediately afterwards: namely that the BigGood is, after 15 years (in story) and 10 volumes, most definitely ''[[HesBack not]]'' dead.

* Episode 9 of ''Manga/WanderingSon'' has Takatsuki going to school [[spoiler:in a boys uniform]]. Later in the episode Doi meets Yuki and we learn she's a transitioned {{Transgender}} person. At the end of the episode, [[spoiler:Nitori goes to school in a SailorFuku and wig]].
* 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.
* ''Anime/WitchHunterRobin'': Episode 12.
* ''Manga/TheWorldGodOnlyKnows'' had this going from the start of the ''Goddesses Saga'' up until the concluding portions of the ''Heart of Jupiter Saga'':
** FLAG 116 has two Whams in quick succession, following an earlier Reveal: [[spoiler: that Kanon is the holder of the goddess [[DistaffCounterpart Apollo]], and thus remembers Keima. Wham One: Kanon publicly confesses her love to him. Wham Two: Kanon suffers a critical stab wound, marking a significant turning point in the series]].
** If that was not wham enough, then FLAG 165 to 168 should hit hard like an oncoming rig. [[spoiler: In summary: Chihiro confesses her love to Keima; the latter gets confused as to how she came to like him even before her conquest; Ayumi is then revealed to actually have the last goddess; Keima is then forced to dump Chihiro, with Ayumi watching on, then later enters into a semi-HeroicBSOD state realizing the mess he entered himself into... Somebody say "Four-Wham-Pileup?"]]
** Then there's [[spoiler:FLAG 174 / ''Goddesses Arc'' Episode 10. Lune has assembled a team to capture one of the Goddesses hosts during the Mai High Festival. However, she doesn't know who that girl is. The solution? Order her minions to capture all of the girls Keima's conquered before at the festival! This forces Keima's hand regarding his conquering of Ayumi.]]
** FLAG 214 has [[spoiler:Keima and Elsie finding Urara's grandfather HalfTheManHeUsedToBe, but still alive, getting discovered by Vintage, and Dokurou ripping and squashing said Vintage members apart with her ''bare hands''. Very messily. Dokurou then reveals she knows about Keima's mission, telling him the current timeline will lead to a bad future, and triggers the ResetButton to give him another chance.]]
** FLAG 260. After the intense and ''brutal'' fight last chapter between Lune and [[spoiler:Nikaido/Dokuro]], the plot doesn't waste time into making everything even worse. [[spoiler:[[McGuffin The orb]] [[OhCrap breaks]]. '''''{{Time Crash}}es.''''']]
** FLAG 266, [[AssPull FULL STOP]]. [[spoiler: Freakin' '''''Elsie''''' is Satyr's ultimate WeaponOfMassDestruction.]]

* Episode 12 of the ''Manga/{{X1999}}'' anime: Kamui chooses to be a Dragon of Heaven, making Fuuma become a Dragon of Earth, and switch personality. After that, Fuuma throws Kamui into a wall, steals his sword, pins him to a wall with shards of glass, piercing his hand with the sword, licks his neck, and proceeds to crucify his own sister and kill her.

* ''Anime/YuGiOh'' has a tradition for [[InvincibleHero having their protagonists almost never lose a duel]], so almost any episode where they ''do'' lose counts as this. One of the more notable examples is Yugi losing in Season 4 to Rafael. Unlike most of the villains and most of Yugi's past defeats, Rafael didn't have to cheat to beat him, ''he won fair and square''. Sure, he forced Yami Yugi to play an evil card, but he did it by backing him into a corner so he had '''no''' choice but to use it, then took a pummeling and ultimately used Yami Yugi's more brutal and reckless personality against him to win. Cue Yugi losing his soul, Yami Yugi crossing the DespairEventHorizon, and the season suddenly [[DarkerAndEdgier taking on a darker tone]].
** There's also episode 52... in the Japanese version. The dub gave away the big twist in ''the second episode'' (and for some reason the characters are all still surprised come episode 52).
** The beginning of the Duelist Kingdom arc served as one in the manga. Although it served as the first episodes of the anime, reading the manga for the first time made it pretty damn shocking when Yugi came across the Duel Monsters creator who also turned out to be another wielder of the Millennium Items.
* After two rather light-hearted seasons that got no more serious than the previous show, ''Anime/YuGiOhGX'' suddenly pulled season three on us, which got as dramatic as the end of the second season about ten episodes in. The really dramatic turning point, though, is the duel again Professor Satou where Judai starts to crack, we see a crazy guy with petty motives that aren't, [[TheReasonYouSuckSpeech quite]]. The first duel where Judai really isn't enjoying himself, and at the end Satou ''dies'' by falling off the bridge. And it only goes downhill from there.
** Season 2 wasn't all light-hearted. Episode 65 comes to mind. Ryo, mentally and emotionally falling apart because of his inability to cope with failure, becoming trapped in an Underground arena, and horribly tortured into a truly disturbing FreakOut and FaceHeelTurn. His KickTheDog in Episode 95 might count too.
** TheReveal of [[spoiler:Daitokuji-sensei]], of all people, was Amnael, the last of the Seven Star Assassins.
* Episode 107 of ''Anime/YuGiOh5Ds''. First, Bruno jumps off a cliff then becomes Dark Glass. He proceeds to duel Placido while Yusei gets magical cards from a giant obelisk that he teleported to. He proceeds to meet what may be God, and then goes back and takes over in Dark Glass's place. Then, Placido fuses with his motorcycle.
* Anime/YuGiOhZexal: The last two Barian Emperors are [[spoiler: Shark and Rio]].
* ''Manga/YuYuHakusho'' Yusuke solves what seems like just another case...only to have Toguro, the supposedly dead hired muscle from that case, reveal himself to be alive and far more powerful than Yusuke could have imagined. Yusuke is thus forced to fight for his life in the Dark Tournament.
* ''Anime/YuriOnIce'':
** Episode 7. You know, TheOneWith [[spoiler:that infamous TheBigDamnKiss -- yes, it did happen.]]
** The writers have stated that Episode 10 was a filler. Yet, after watching it, you have to [[RewatchBonus watch the whole show from the start]], because the episode changes everything that's happened up until that point, particularly regarding [[HeartwarmingInHindsight Victor's interactions with Yuri]], and [[HilariousInHindsight Christophe and Yurio's relationship with Yuri]]. And most of all, the development of the plot as a whole gets an entirely deeper meaning.
** Without explaining why, Episode 11 is by far the most emotionally-devastating one of them all.
