History SpoilerOpening / AnimeAndManga

** The first Japanese opening shows not only Guilmon's, Terriermon's, and Renamon's Champion forms, it shows their Ultimate and Mega forms too. Then around the time of the Digital World arc, the second Japanese opening gives away Impmon digivolving into Beelzemon and pulling a FaceHeelTurn. To make things worse, it also spoils him going into Beelzemon Blast Mode, which also spoils him [[HeelFaceTurn rejoining the good guys]] and getting a RedemptionPromotion, since he doesn't have wings and an ArmCannon while he's a villain, and Digimon only change that drastically through ThePowerOfFriendship.

*** It shows the Beast Titan's SpamAttack of boulders shredding the Survey Corps soldiers.

** The third opening shows Eren's titan clashing with the Armored Titan, which does not happen until episode six of the opening's run time. It also features the Colossal Titan tearing down the wall, as well as the Beast Titan running alongside various outlandish animals such as dinosaurs and flying whales, but these turned out to only be [[RedHerring Red Herrings]] as nothing of that sort actually happens in the story. Though the latter one sure did lead to a lot of WildMassGuessing, especially from confused manga readers.

* ''Manga/AttackonTitan'' has a few offenders.
** The second opening shows the Female Titan several episodes before she makes an appearance in the series. The AvengersAssemble sequence near the start of the opening also ends with Annie, whom the camera follows as she ominously turns around with a determined look on her face, which, to those who are GenreSavvy, can makes it quite apparent as to who the Female Titan actually is. [[CaptainObviousReveal Not that it's hard to figure out just from watching the show.]]

** The opening for the 2 {{Compilation Movie}}s, however, plays this straight. It has many scenes of Madoka and Homura acting like [[RomanticTwoGirlFriendship best friends, or possibly lovers]]--but Homura is the ''antagonist'', initially, and doesn't seem to care about Madoka very much until halfway through the second movie. A shot of Homura in front of a giant clock surrounded by gears strongly implies she has time-manipulation powers, a big spoiler from near the end of the first movie. It still gives a misleadingly upbeat vibe, though, making it seem [[SoundtrackDissonance out-of-place]] when it plays right after the extremely dark opening scenes of the second movie.

* The opening for the second season of ''Manga/FoodWars'' shows all the matchups (and hints at who wins) for the quarterfinals and semifinals of the Fall Classic, though the symbolism may not be clear until after watching the episodes. Each pair of competitors ([[spoiler:Soma and Alice, Takumi and Mimasaka, Ryo and Megumi, and Akira and Hisako]]) appears together trying to knock each other off a [[RuleOfSymbolism giant flying knife]], and then [[spoiler:Akira decimates them all with his cinnamon "cannons"]], hinting that he will be the ultimate winner. It's heavily hinted that the final will be [[spoiler:a three-way battle between Akira, Soma, and Ryo]], since they're the only ones still standing on their knives at the end. Also, [[spoiler:Kojiro]]'s return is hinted by him appearing too, though he doesn't show up beyond a brief cameo until the last episode of the season.

** The first opening for ''[[Manga/JojosBizarreAdventureVentoAureo Vento Aureo]]'' shows Bruno Bucciarati (who fights against Giorno in the second episode) as a main protagonist, all the gang members and their stands, as well as Trish. The second opening shows Trish's Stand, and more notably Giorno stabbing himself with the arrow and gaining a new power, which happens at the end of the FinalBattle.

* ''Manga/FutureDiary'''s opening is LOADED with spoilers, except they are either so subtle you don't notice them, Blink-and-you-miss-it, or completely incomprehensible for those who have not read the manga. For example, the scene of Yuno fighting herself and two halves merging together seemingly looks like it was thrown in to be frantic and creepy with a heavy dose of artistic license, but it actually foreshadows a major plot twist that occurs later on in the story.

* ''Manga/YuGiOh'':

** The second Japanese opening, "Shuffle", manages to spoil the fact that Yugi obtains Slifer the Sky Dragon/Osiris. If you look closely at the scene near the end of the opening (which features Yugi, Marik and Kaiba), you can see the Slifer card in Yugi's hand.
*** The opening itself came in at the end of episode 49 (weirdly the last part of the Dungeon Dice Monsters arc, not the start of Battle City), and Yugi got Slifer in episode 67. To further make it a slight spoiler, Kaiba is shown twice with the God of Obelisk/Obelisk the Tormentor card. He obtains the card in episode 52, just 3 episodes after the opening came into use, so it's not as major a spoiler as Yugi getting his God card. The only other major spoiler for this opening is Yugi summoning the Black/Dark Magician Girl, a monster that doesn't appear until 12 episodes later.

* ''Franchise/PrettyCure'' has its own page [[SpoilerOpening/PrettyCure here]].

* Spoiler ''ending'' in ''Manga/MonsterMusume'''s case. With the credits showing the MON squad, revealing that there's a special monster squad, who clearly have a connection to Ms. Smith, and don't show up till much later. The opening itself is also mildly spoilery, as it reveals all but one of the girls who end up in Kimihito's harem.

* ''Anime/{{Pokemon}}'':
** Most of English openings spoil future captures and evolutions that the characters are going to have. The Japanese openings and endings are usually better about this since they change to match the trainers' current parties, but some spoilers still slip through.
** The Japanese first opening shows Satoshi's Pidgeot fighting a Fearow. His Pidgeotto doesn't evolve until it fights a Fearow, which happens at the end of the first season, which is also the episode where it leaves Satoshi's team.

** [[PlayingWithTropes Played with]], in the opening credits prominently feature Madoka in her MagicalGirl form, making it obvious she will transform fairly early on. She doesn't. As the episodes went on all the main characters except Madoka had made contracts. By the tenth episode we realise that the whole point is that she ''doesn't'' become a magical girl, making the opening a form of BaitAndSwitchCredits. However, the trope is eventually PlayedStraight when Madoka transforms in the ''final episode''.

* The second opening for ''Anime/LupinIIIGreenJacket'' series introduces Goemon as a member of Lupin's gang, before he even appears, spoiling his HeelFaceTurn.

* ''Manga/JoJosBizarreAdventure'':

** The first opening for the ''[[Manga/JoJosBizarreAdventureStardustCrusaders Stardust Crusaders]]'' anime shows Kakyoin and Polnareff fighting as part of the group, even though they initially appear as antagonists; additionally, during the shot of five stars shooting towards Dio's lair, a sixth one joins the group, foreshadowing SixthRanger Iggy. The second opening shows, although much faster, shots mirroring those just before the deaths of Avdol and Kakyoin, as well as the near-death of Joseph, and is replete with clock/gear imagery representing the fact that Dio's Stand can stop time. And there are ''many'' more [[FreezeFrameBonus split-second]] ones, such as Jotaro's hand moving during Dio's time stop and the World appearing in Star Platinum's reflection.

** The first opening for ''[[Manga/JojosBizarreAdventureVentoAureo Vento Aureo]]'' shows Bruno Bucciarati (who fights against Giorno in the second episode) as a main protagonist, all the gang members and their stands, as well as Trish. The second opening shows Trish's stand, and more notably Giorno stabbing himself with the arrow and gaining a new power, which happens at the end of the FinalBattle.

* The ending of Episode 13 of the ''Anime/AceAttorney'' anime strongly implies that Miles Edgeworth is going to die, and in Episode 14 Phoenix outright states that he's dead. However, the latter episode also debuts a new opening in which Edgeworth is ''heavily'' featured, including shots of him standing in Times Square, pretty much spelling out that he isn't dead at all, just abroad. Sure enough, after a couple of quiet hints, Edgeworth shows up alive and well at the end of Episode 20. Of course, [[LateArrivalSpoiler you'd know this if you'd played the games]].

** The first opening ''shows'' major events in ''[[Manga/JoJosBizarreAdventurePhantomBlood Phantom Blood]]'': The BigBad being shot at by the policemen with an image of Jonathan holding his father's corpse reflected in shattered glass.
** The opening of ''[[Manga/JoJosBizarreAdventureBattleTendency Battle Tendency]]'' spoils Caesar's death. Specifically the part where Joseph ties Caesar's headband around his head while crying out towards the sky, and Caesar's last Hamon bubble (the bloody one). Kars' eventual immunity to sunlight is also foreshadowed, albeit more subtly since the shot of the sun rising behind his back is only a split second long. Some shots in the opening also foreshadow Joseph's stand for a split-second.

** The first opening for ''[[Manga/JojosBizarreAdventureVentoAureo Vento Aureo]]'' shows Bruno Bucciarati as a main protagonist, all the gang members and their stands, as well as Trish. The second opening shows Trish's stand, and more notably Giorno stabbing himself with the arrow and gaining a new power, which happens at the end of the FinalBattle.

* The first opening of ''Manga/BoboboboBobobo'' spoils several characters' {{Heel Face Turn}}s, though the inclusion of Captain Battleship among the main cast when he never actually joins up may have been an attempt to partially avert this. (of course, few people watch Bo-Bobo for the plot)

* Spoiler ''ending'' in ''Manga/DailyLifeWithMonsterGirl'''s case. With the credits showing the MON squad, revealing that there's a special monster squad, who clearly have a connection to Ms. Smith, and don't show up till much later. The opening itself is also mildly spoilery, as it reveals all but one of the girls who end up in Kimihito's harem.

* ''Anime/MaiOtome'':
** The opening spoils the appearance of Miyu in later episodes, in addition to showing a shadowy mysterious Otome, who might have not been prematurely identified as Mai, if not for her ''mitsu tomoe'' symbol from ''[=My-HiME=]''. And of course, it also spoils the "will Arika get into Garderobe?" subplot of the first few episodes.
** Starting with episode 16, a new set of opening credits appears... which not only reveals the (albeit well foreshadowed) major plot twist that hasn't happened yet, it also removes any doubt as to which side every character will wind up on.
** Both openings, however, show a character in silhouette whose identity remains successfully hidden until the very last episode.

* The ending themes for ''Manga/KaguyaSamaLoveIsWar'' (barring the single epsiode "Chika Dance", which was just a bunch of disconnected {{Mythology Gag}}s) blatently spell out the events for the final arc of their respective seasons, though they're wrapped up in enough fantasy imagery that only those who are familiar with the source material would pick up on in ahead of time. The opening for season 2 also shows Miko as a member of the Student Council despite the fact that she doesn't join until half way through the season.

* The ''Manga/RiddleStoryOfDevil'' OP is quite spoilery, and not just because it completely blows the LateArrivalSpoiler that Tokaku will side with Haru. It also strongly suggests two things that happen much later: Sumireko is the final regular opponent (as opposed to Nio, who's sneaky about it) and Tokaku herself is still dangerous. The battle sequence also shows most of the assassins using the weapons they'll eventually fight Haru and Tokaku with -- and yes, the fact that Shiena only ''gets'' attacked should tell you something, as should Hitsugi hiding behind Chitaru.
