History SpoilerOpening / AnimeAndManga

* ''Manga/{{BECK}}'': Besides showing a few characters that don't appear for quite a few episodes, it also reveals that the band was [[MusicalSpoiler "made to hit in America!"]] The idea of the band going for an overseas market doesn't come up ''at all'' until more than halfway through the series.

** The first Japanese opening shows not only Guilmon's, Terriermon's, and Renamon's Champion forms, it shows their Ultimate and Mega forms too, albeit in silhouette. 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 that he has further plot developments beyond his initial arc, since he doesn't have wings and an ArmCannon even by the end of his first batch of episodes.

To make things worse, it also spoils him going into Beelzemon Blast Mode, which also spoils that he has further plot developments beyond his initial arc, since he doesn't have wings and an ArmCannon even by the end of his first batch of episodes.

* The ending themes for the first two seasons ''Manga/KaguyaSamaLoveIsWar'' (barring the single epsiode "Chika Dance", which was just a bunch of disconnected {{Mythology Gag}}s) blatantly 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 halfway through the season.

* ''Manga/{{Kekkaishi}}'':
** ''Kekkaishi'' does this the other way around, the OP shows the 3 good guys together but in the anime the third person joins up later in the series only to be killed off soon after, surprisingly the OP never changes.
** Well, there are some changes to accommodate major enemies or allies in the relevant arc. But for some reason they don't change anything else.
** The OP also show Tokine using long, thin kekkai to skewer her enemies, a trick she doesn't learn until around the half-way point, and that she uses to compensate for not having Yoshimori's raw power.
* The opening for the Manga/KemonoJihen anime presents Kon as one of the main characters. Spoilering her HeelFaceTurn. It also somewhat spoils hers and Kabane's RelationshipUpgrade by showing their LiterallyFallingInLove scene. Though without context.

* The Italian dub theme song for ''Anime/DragonBallGT'' shows characters such as SS4 Goku, SS4 Vegeta, Rage Shenron and SS4 Gogeta, which appear all in the latter part of the series. A few times they also aired an extended version of the theme song, which features scenes such as Goku eating the 4 star Dragon Ball so that Syn Shenron can't get it and the aforemented ball emerging out from Goku's forehead after the final battle.

* ''Anime/AceAttorney'':

* ''Manga/{{Shiki}}'' does this with it's first OP. By showing who's going to be turned into a Shiki by skullifing them.

** The third opening would be a full aversion... if it weren't for showing Miss All-Sunday, aka Nico Robin [[HeelFaceTurn as part of the crew]], ruining one of the series' biggest twists. The fourth is pretty much a full aversion, unless you count the brief flash to Robin's past (which even the manga hadn't revealed back then; it's possible the anime writers only got vague hints from Oda).

** Even the Japanese version of ''5Ds'' began doing this, with the forms of Shooting Star Dragon and Machine Emperor Grannel. Initially, for the fourth opening, they were obscured (the former in light, the latter in shadow). This had been done before, with the creature being added the episode after they appeared. With these two, however, they were added into the intro of the very episode they debuted in, thus ruining the anticipation.

* The first opening of ''LightNovel/GoldenTime'' portrays Kouko and Banri as a couple, even though their coupling doesn't happen until several episodes in.

* The opening and closing of ''LightNovel/{{Kampfer}}'' make it nigh-impossible to not figure out who's on what side. [[FriendlyEnemy It doesn't make much of a difference anyway.]]

* ''LightNovel/{{Oreshura}}'' initially only has Masuzu and Chiwa competing for Eita's attention; but the opening and ending reveal two other UnwantedHarem-ettes, who don't appear in the actual show for several episodes.

* While the ''LightNovel/{{Baccano}}'' opening mostly just shows general scenes or {{Establishing Character Moment}}s (such as Isaac and Miria [[RefugeInAudacity robbing a bar of its candy bars while dressed as Santa Claus and the Headless Horseman]]), it does make an exception in the case of Dallas, by showing his eventual fate instead: [[AndIMustScream perpetual]] CementShoes drowning. And The Young Conductor shows up rather prominently in the credits, despite the fact that by Episode 2, he would appear to be dead. On the other hand, unlike all the other prominent characters, he isn't given a title card, so it's easy to write off, or even miss entirely.

* ''Anime/BlackBullet'' zig-zags this. The first few episodes use a TitleMontage, with the real intro only appearing after a few key plot elements shown within it (such as Rentaro's bionic enhancements and supporting character [[ChildSoldier Tina Sprout]]) have been introduced. However, said intro depicts Rentaro fighting with Kagetane, who he supposedly defeated for good two episodes previously, spoiling the fact that he's NotQuiteDead. Sure enough, he returns in Episode 11... only this time he's working ''with'' Rentaro [[EnemyMine to help defeat Aldebaran]].

* In ''LightNovel/{{Campione}}'', Liliana first shows up as a vassal of the Marquis Voban, and her HeelFaceTurn is later. However, both the OP and ED display her as a member of the harem, making the outcome of those events rather foreordained.

* The opening of ''LightNovel/CoffinPrincessChaika'' spoils, or at least heavily foreshadows, the existence of the other Chaikas, even showing Chaika casting aside a blue veil in an identical manner to Layla/Blue Chaika during TheReveal. It also shows an injured Toru falling into the water in [[CollapsingLair the sinking Soara Fortress]], and Chaika diving in after him, as happens in the final episode.

* The first opening of ''LightNovel/{{Durarara}}'' shows us Celty's head. Surprisingly, it doesn't reveal the name of Seiji's girlfriend, at least in the translated credits.

* ''LightNovel/TheFamiliarOfZero'' shows the WWII Zero fighter, related to Siesta's heritage.

* The ending of the ''LightNovel/FateZero'' anime shows brief scenes of all the Servants' former lives. These are mostly vague (e.g. we learn that one character from Greek myth or history will be used, but not who that person is) but it's certainly possible to make a shrewd guess at Berserker's identity. Which is also the only one ''not'' revealed early on in the series. It's also possible to correctly guess their identities [[GeniusBonus if you recognize what art pieces each of their sequences are based off of]].

** The second opening has a number of visual spoilers. And then there are the lyrics, which are in a hard to understand english, but once you understand it it reveals pretty much everything, including the time-travel plot, a LONG TIME before this happens in the story.
* The opening of the seventh ''LightNovel/TheGardenOfSinners'' film prominently displays Lio's StalkerShrine to Shiki and his drug producing operation, both of which are key reveals. [[DownplayedTrope However]], it's presented in such a stylized manner that most viewers wouldn't pick up on it unless they'd already seen the movie before.

* ''LightNovel/IsItWrongToTryToPickUpGirlsInADungeon'': The second season opening shows the Hestia Familia crew living in a giant mansion, quite unlike the tiny run-down house they had in the first season. They don't get this massive residence upgrade until the end of episode 4, when they beat the extremely wealthy (and extremely evil) Apollo Familia in a "war game" and claim everything they own as a reward.

* The Season 1 opening of ''LightNovel/LogHorizon'' pretty much spells out the entire plot of the season, from Demikas and Nyanta's fight early on to the goblin/sahagin invasion (doesn't happen until Episode 15), Lenessia's speech to the adventurers (doesn't happen until Episode 19), to Rundel Haus' death during the aforementioned invasion (doesn't happen until Episode 19).

* The main premise of the series ''LightNovel/MariaWatchesOverUs'' is that of the ''soeur'' ("sister") system: characters choose underclassmen to be their ''Petite soeur''. While the series tries to build suspense as to who will choose who, the opening sequence shows the pairs quite plainly. In the second season, there is supposed to be a rivalry between two of the girls, though we clearly see them as ''soeurs'' in the opening. The fourth season has an additional spoiler ''ending'', since it clearly showcases who Yumi will choose as her ''soeur''.

* ''LightNovel/{{Slayers}}'' tries to set you up to see Rezo as a good guy and Zelgadis as a villain. Now look at who Lina and Gourry are attacking in the opening and who shows up in the "hero" section of the TeamShot at the intro's end.

* The second opening of the anime ''LightNovel/SwordArtOnline'' pretty much spoils what happened to Asuna at the end of the game, where she is, the fact that Yui is there too, and what is going to happen from episode 16 onwards. The first opening isn't really an example of this trope, as the biggest spoiler it has is Asuna's face behind the cape she wears in the first part of episode 2.

** The opening credits of ''Sword Art Online II'', based on a later [[LightNovel/SwordArtOnline story arc]], completely spoils Kirito's [[SuperReflexes incredible swordsmanship]] using a [[JokeWeapon lightsaber weapon]], in a [[NeverBringAGunToAKnifeFight game dominated by guns]].

* ''LightNovel/{{Toradora}}'': Ami Kawashima appears in the opening from the first episode on, even though she appears first in the fifth episode.

* The opening for the Manga/KemonoJihen anime presents Kon as one of the main characters. Spoilering her HeelFaceTurn. It also somewhat spoils hers and Kabane's RelationshipUpgrade by showing their LiterallyFallingInLove scene, though without context.

** Episode 7 has [[spoiler:Kokkuri [[GenderBender turn into a woman]]]], which not only isn't resolved by the end of the episode but remains in place at the start of the next, leaving open the possibility that it will stick for the rest of the series... except that, for all the effort they go through to continually update the opening to account for every other new character and development, [[spoiler:Kokkuri's transformation]] is only reflected in the final shot, giving away that it won't last.

** The first season of [[Anime/FullmetalAlchemist the 2003 anime]] waited until the end of the episode to play its opening, specifically to avoid giving away the [[FirstEpisodeTwist first episode plot twist]] that would have otherwise been spoiled by the opening.

** Dub theme contains several major spoilers toward the end. ''Three'' Super Saiyans are shown, including one who hasn't even appeared yet (Future Trunks, ''slicing Frieza in half'' for a split second, who ''also'' hasn't appeared yet -- and in his final form to boot!). The worst one is Vegeta's inclusion in the final group shot, which makes it obvious that he'll end up a good guy; this is a spoiler you can ''understand'' almost right away, but which takes a long, ''long'' time and a lot of character development to happen.

* ''LightNovel/AccelWorld'':

* The scenes near the end of ''Anime/AkudamaDrive'''s opening sequence [[{{Foreshadowing}} foreshadows]], the Akudama's [[KillEmAll eventual death scenes]].

* The ending themes for ''Manga/KaguyaSamaLoveIsWar'' (barring the single epsiode "Chika Dance", which was just a bunch of disconnected {{Mythology Gag}}s) blatantly 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 halfway through the season.

** ''Shippuden'' opening 15 trumps all previous examples. It shows the resurrected Ten-Tails, Naruto cradling Neji's body, Hinata crying, and then Naruto and Hinata HoldingHands, followed by a montage of Kakashi fighting an unmasked Obito, as well as Hashirama fighting Madara, and even Hashirama and Madara as children. Also depicted are the four resurrected Hokages, and Naruto and Sasuke seemingly fighting together - hinting at Sasuke's HeelFaceTurn. Taking it UpToEleven is a shot of Might Guy looking to be undergoing a power up, hinting at a certain subsequent manga development, and the final shot even shows Obito as the Ten-Tails' Jinchuriki.

** However the second just cranks the spoilers UpToEleven. In 85 seconds, we learn that some bad guy (most likely a Mikene, a member of Zeus' race) comes to earth, and boy does he look pissed; we get a good look at some of the enemy robot designs that'll probably be used in upcoming episodes; we also learn Mazinger is going to fight an EvilTwin; ever wondered how Mazinger turns into the [[RocketPunch Big Bang Punch?]] Well its right there for you! Baron Ashura seems to be about to relive past experiences; Tsubasa is going to have a really bad day; and we get a nice good look at Tetsuya and his mecha, though it might not be Great, since it really doesn't resemble it all that much.

** If you know what to look for, the ''LightNovel/{{Slayers}} Next'' opening spoils Gourry being kidnapped, the appearance of Lord of the Nightmares (twice, even!) and the Ragna Blade. Ironically, it doesn't spoil the anime per se, but the original ''novels'', by showing the Sword of Light being lost to the darkness.

* The dub opening for ''Anime/SonicX'' shows Shadow opening his eyes. Shadow doesn't appear until a little while into the second season. He's also seen in the Japanese opening. To be fair, much of the fanbase was made up of people who beat some of the games. They had whole arcs spoiled for them before the series premiered.

** Averted later on in the series. Kamina features prominently in the intro until the episode after he dies. Also, the full Gurren Brigade and Dai-Gurren are absent, despite their importance, until this point. There's also an interesting subversion at work here considering Thymilph doesn't appear in the opening until AFTER he dies.

* ''Manga/DemonSlayerKimetsuNoYaiba'': The opening for the Entertainment Distict arc shows Warabihime make a SlasherSmile and unleash her belts, spoiling that she is the demon that Uzui and Tanjiro's group is huning... or rather, ''one'' of them. Her brother Gyutaro, who doesn't show himself until the first time Daki's head is cut off, is shown in the moonlight late in the opening and unleashes [[BloodyMurder his Blood Demon Art]] on Uzui, spoiling the primary twist of the arc- that the Upper Rank 6 is composed of ''two'' demons.

** 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 spoils [[FirstEpisodeTwist a twist from the third episode]]- Dio becoming a vampire and killing George Joestar.
** 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 opening for ''[[Manga/JoJosBizarreAdventureDiamondIsUnbreakable Diamond is Unbreakable]]'' likewise shows Okuyasu standing alongside Josuke, Koichi and Jotaro in spite of being introduced as an antagonist. Its second opening spoils the appearance of Echoes Act 3 and Yoshikage Kira's status as the BigBad.

** The first season of [[Anime/FullmetalAlchemist the 2003 anime]] averted this by having the [[FirstEpisodeTwist first episode plot twist]] spoiled by the opening scene by placing the intro at the end of the episode.

** Meanwhile, ''[[Manga/FullmetalAlchemist Fullmetal Alchemist: Brotherhood]]'''s first opening has three shots of Hohenheim, who, in the manga, doesn't really show up for another 10 volumes. One of the shots is even Hohenheim as a young slave. In their defense, Slave!Hoho is so ambiguous that someone who doesn't already know what it means will probably incorrectly take his appearance as a spoiler that Ed gets his arm back. The first opening also shows the alchemy diagram for human transmutation intact, which is a significant plot point much later in the series. As with Hohenheim's slavery, it's ambiguous enough that it's not a major spoiler.

* ''Manga/JoJosBizarreAdventure'' often has its openings spoil later events, although some of the spoilers are subtle enough to be {{Foreshadowing}}:
** 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 spoils [[FirstEpisodeTwist a twist from the third episode]]- Dio becoming a vampire and killing George joestar.

** 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 on the far right of the shot, 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/JojosBizarreAdventureGoldenWind Golden Wind]]'' 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.

* Subverted by ''Manga/SoulEater'' with its 2nd opening, which shows Soul screaming in anguish while holding a limp Maka in his arms. It would make for a very dramatic death scene or whatnot... except [[BaitAndSwitchCredits nothing like that actually happens during this part of the series]].

** Chrona makes a prominent appearance in the first opening, so we end up watching him/her for several episodes before he/she actually appears.
** The fourth ED is essentially a spoiler for the end of the series; a monstrous Asura being fought by the main teams, the adults rendered useless (if not apparently dead) with the kids left to save the day and Soul and Maka featuring most prominently. One point that doesn't correlate to the finale is that it's Soul supporting Maka - similar to the switch around in the second OP - when again it's the other way around. Another is that a panicked Crona is standing over what appears to be a small child's corpse, implying that zhe killed Medusa even though [[ShootTheHostage she was still possessing Rachael]]--but Crona actually couldn't go through with it, then Maka managed to defeat Medusa without harming her hostage.
