A way of avoiding a SpoilerOpening, gradually changing the opening or closing instead of showing everything at once. Characters who haven't been introduced may appear as [[SinisterSilhouettes silhouettes]] or not at all (until they get a PromotionToOpeningTitles), and certain scenes may change over time to reflect recent events in the story to demonstrate TheReveal.

This is becoming increasingly obvious in {{anime}}, but it may or may not carry over into the series' foreign broadcasts.

!!Examples

[[foldercontrol]]

[[folder:Anime]]
* ''Manga/CardcaptorSakura'' had Shaoran appear briefly in the opening credits only after he was introduced; the American version (even the subtitled version) used one set of credits for almost everything, missing this.
* ''Manga/CrossGame'' does this very subtly. The heroine is from a family of four sisters who together are (in show) symbolized by a four leaf clover, which appears in the show's title logo. (See the image on the ''Manga/CrossGame'' page.) After the first episode, [[spoiler: one of the leaves is faded, as the corresponding sister dies in the first episode.]] In the series finale, [[spoiler:the leaf returns to full color once again, symbolizing that the cast have finally come to terms with Wakaba's death.]]
* ''Manga/DeathNote''
** In the first opening, Watari is in silhouette and trenchcoat until the series shows his true appearance. Although, curiously, L's much more mysterious and intriguing appearance DOESN'T get this treatment.
** They also subvert the trope with Naomi Misora, showing her well before her introduction [[spoiler:and for quite some time after her death.]]
** Of course when it came time to adapt the second arc, the same second spoilerish opening was used [[spoiler:even long after L and Watari's deaths]] and wasn't updated to give more focus to the "new" characters, perhaps foretelling the less focus that the second arc would get in the anime.
* ''Franchise/{{Digimon}}''
** ''Anime/DigimonTamers'' and ''Anime/DigimonSavers'' feature these by unshadowing the higher level Digimon (and in the case of the latter two, unshadowing the [[SixthRanger Sixth Rangers]]) as the series progressed.
** ''Anime/DigimonXrosWars'' did a variant in its second opening - initially in the sequence where Shoutmon and Greymon warp through all their Xrossed forms the sequence stops at the point where Shoutmon X5 and [=DeckerGreymon=] form and switches to stock evolution footage to illustrate [=OmegaShoutmon=] and [=ZekeGreymon=], padding it out slightly. When Shoutmon DX and Shoutmon X7 showed up, the stock footage was removed and the full "warp" sequence was played adding in Shoutmon DX and Shoutmon X7.
** The opening of ''Anime/DigimonAdventure02'' was altered slightly partway through, switching and editing a couple of scenes to reflect the change in antagonists, Ken's SixthRanger HeelFaceTurn and the newfound availability of natural evolution. This was the only time the opening was changed, so it ''still'' managed to [[SpoilerOpening spoil the existence of both of Imperialdramon's forms]]...
** A rare example of a translation doing this: the English dub of ''Anime/DigimonAdventure'' added Kari and the higher level digivolutions to the opening partway through the series.
* ''Anime/BestStudentCouncil'' uses the "simple" revealing-silhouettes version.
* ''Franchise/{{Gundam}}''
** The second opening for ''[[Anime/MobileSuitGundamSEED Gundam SEED]]'' features the Freedom Gundam with its wings deployed in silhouette, many episodes before its debut. The third opening, which started playing at least a dozen of episodes before the Freedom's actual debut, has it launching from the Archangel's linear catapult and in a few action scenes with the Justice Gundam, which also did not get its debut until an episode or two after the Freedom's. Subsequetly, in ''Destiny'''s first opening, the same scene shown in ''SEED''s second opening is shown again, this time without the shadowing.
** ''[[Anime/MobileSuitGundamSeedDestiny Gundam SEED Destiny]]'''s second opening features shots of three future Gundams (Destiny, Strike Freedom, and Destroy) fighting one another in silhouette; by the time the third opening comes, all three have been revealed in-series, and thus the sequence returns ''sans'' shadowing.
** ''Anime/AfterWarGundamX'' has a silhouette of the Gundam Double X showing up as it starts to influence the plot; the OP changes completely after it becomes Garrod's MidSeasonUpgrade.
* The opening of ''Anime/GunXSword'' silhouettes everyone who hasn't yet shown up in a sort of violet-blue aether, and everyone and everything who has been killed or destroyed in solid black shadow. The end credits do something similar, showing various "casual" pictures of major characters. In the beginning, they're all of Van and Wendy; as the cast expands, pictures of the newcomers replace various shots in the montage.
* Halfway through the series, the opening of ''VisualNovel/HigurashiNoNakuKoroNi Kai'' added two scenes with [[spoiler:Hanyuu]] and slightly modified another to reflect a very important event that had just occurred. A variation from the same intro was a playback to the gory, PoorConnectionKills time (Rena's machete) being replaced with a scene where the connection was fixed. It's a variation since it was due to ''censorship''.
* In ''LightNovel/InfiniteStratos'' (pictured), the ending credits change as [[PromotionToOpeningTitles more girls are introduced]]; the most significant change is that since the ending theme is sung by these girls' voice actors, the song progressively gets more and [[EvolvingMusic more complex as the verses get distributed between more voices]]. It also hints at how close the girls are to Ichika, the main male protagonist, and the closer the girl is to him in that episode, the closer they're running behind him during the ending credits.\\\
In hindsight, [[spoiler:the ending credits have a stealth spoiler in the form of Charl who appears in the credits right after her introduction... even though it takes a few more episodes to reveal her real gender (and when that happens, her appearance in the credits changes accordingly). The spoiler comes from the fact that aside from Ichika, everyone else who appears in the credits is a girl.]]
* ''Manga/{{Karin}}'''s opening avoids this by having a character who hasn't been introduced yet be seen only in a silhouette until after their first full episode as part of the cast, although their rather unique form makes it hard ''not'' to guess who it is when they first appear...
* ''Anime/{{Moldiver}}'' replaces the central figure in its credits once it becomes clear in the story who the ''real'' hero is.
* ''Manga/{{Naruto}}'' is particularly fond of this in its many openings.
** The fourth and fifth changed with the introductions of Tsunade, Shizune, Kimimaro, and so on, and certain characters disappeared after they "died".
** The first opening for ''Shippuden'' changed after the reintroductions of Team Guy and the Sand Shinobi, as well as the introduction of Chiyo. The fourth opening recycled scenes from the third for a while until that season's BigBad was ready to make her entrance.
** Technically, the scenes from when Asuma, Shikamaru, [[ThoseTwoGuys Izumo and Kotetsu]] fight Hidan and Kakuzu in the third opening were most likely supposed to be originally part of the fourth opening, given that they flow better with the fourth song and the animation, and were included to show that the show had moved past the filler arc.
** Later, the second version of the fifth ''Shippuden'' opening transitions from Orochimaru staring at Sasuke as the curse mark spreads at him to [[spoiler:Sasuke killing Orochimaru after he does]], and now features the members of Team Snake.
** Creator/CartoonNetwork / {{Toonami}}'s openings did not follow this format and always kept the first step of the Evolving Credits as the opening for that season.
* ''Anime/{{Pokemon}}''
** Most late openings and endings of have had updates to reflect any changes to a main character's current team.
** Additionally, high-ranking opponents in later seasons, such as Gym Leaders and the Elite Four, are shown in silhouette until Ash manages to meet and overcome them.
** The best example of this was the fourth Advanced Generation opening, Battle Frontier. Each of the Frontier Brains were shadowed in the opening, becoming unshadowed when Ash meets them. This also carried over into the next opening, Spurt!, where the remaining Brains were unshadowed upon appearing. A small gallery of the times the Battle Frontier opening updated its animation can be found [[http://bulbapedia.bulbagarden.net/wiki/Battle_Frontier_(song) here]]
** Best Wishes tops all of them; it features Pikachu running around a black and white field past many Pokemon in silhouette; after those Pokemon are seen in the show, the Pokemon are revealed in the opening.
* ''Anime/SailorMoon''
** A classic example is the original anime, where the early opening only showed three Senshi (before the other two were introduced). The original Japanese edition even had two subtypes of that first opening: before Sailor Mercury was introduced, it had minor differences like the color of the inside of Tuxedo's cape and the three Senshi not removing the veils. From episode 27 onwards a completely different opening was used, now including all five girls, as well as a completely different ending, complete with a new theme.
** ''Sailor Moon R'' did the complete opening replacement as well, introducing Chibiusa and the Black Moon Clan halfway through. (Interestingly, the two openings do ''not'' correspond to the two story arcs of the season in terms of timing, the switch occurs way after Chibiusa's initial appearance.)
** ''Sailor Moon S'', ''[=SuperS=]'' and ''Stars'' do a less radical version of this trope, only altering part of the same opening sequence to introduce new characters. ''S'' pulled off ''three'' versions of the credits, first introducing Uranus and Neptune after they stopped hiding, and later adding Chibimoon, Hotaru and Super Sailor Moon. ''[=SuperS=]'' replaced the Amazon Trio with the Amazones' Quartet once the latter group took over the task. ''Stars'' showed Sailor Starlights as silhouettes until the end of the first arc, which focused on wrapping up the plot of ''[=SuperS=]''; along with Starlights, the second version of the opening introduces [[BigBad Galaxia]].
** Sadly, the Creator/{{Geneon}} uncut DVD release of ''S'' and ''[=SuperS=]'' ignores this and uses the final versions of the opening sequences from the start, spoiling future characters' appearances. ''Stars'' was spared due to [[NoExportForYou never getting an official release]].
* ''Anime/{{S-CRY-ed}}'' did this so much that there is perhaps one case of the title sequence being re-used ''without'' changes in the whole 26-episode series. (Apart from spoiler-based changes, there was also sepia-fading of deceased characters and 3 different main versions for three different verses of the theme tune depending on which of the main characters had the story focus that episode.)
** The Special Edition DVD set has the option to watch just the opening sequence of each episode.
* The first ending to ''Manga/SetoNoHanayome'' consists of a still shot of the characters in a karaoke booth that gradually zooms out. It starts out with only a few characters but gets increasingly crowded as more and more characters are introduced in the series and subsequently added to the mayhem.
* ''Manga/{{Sketchbook}}'' changes part of the OP and ED depending on the primary cast of the episode.
* The opening to ''Anime/TenchiMuyoGXP'' shows four characters as silhouettes. The first three are obviously Tenchi, Ryoko, and Ayeka from the [[Anime/TenchiMuyo original series]], who are revealed in the openings of the two episodes that feature them. The fourth is a new character who is revealed after her first appearance in the second half of the series.
* ''Anime/TsukuyomiMoonPhase'''s Nekomimi Mode OP changes slightly with every episode, including one where Hazuki just plain isn't present ''at all''.
* The parts of the ''Anime/{{Vandread}}'' opening that weren't clips from the upcoming episode; dead characters disappeared from the sequence, and if a character's appearance changed in the series, it would change in the opening soon after. Also, certain spoiler-ish aspects were obscured in the opening, only to be revealed once the plot got to them.
* Weirdly subverted in the closing credits of ''Anime/VisionOfEscaflowne''. For most of the series there is a shot of Hitomi and Allen kissing during the closing credits, however once [[spoiler:they kiss in the actual show]] the shot disappears. (This may not hold true for the official American release as it seems to have just picked one version of the credits and stuck it on to every episode. The original VHS American release only use one version, but the DVD's use both.)
* In each of its four seasons, ''Anime/OjamajoDoremi'' updated its opening (and changed its eyecatches) midway through the season to reflect changes from about that point in the storyline.
* In the opening sequence of the HumongousMecha anime ''Anime/RahXephon'', the title mecha was shown as a silhouette with glowing eyes until a few episodes in. It changes again around halfway through the series to reflect the results of the MidSeasonUpgrade and a few other plot developments.
* ''Anime/{{Planetes}}'' uses this trope extensively, always according to the mood and current plotline. For instance, showing different secondary cast members (or, in one case, in different clothes to show their changing allegiances,) showing an explosion on the moon, a floating compass, or progressively adding color to a sequence that starts out in black and white. Most tellingly, Hachimaki's encounter with his somber "Astronaut" persona during the Opening Sequence becomes increasingly important and denotes his current state of mind.
* ''Anime/TengenToppaGurrenLagann''
** The initial opening and the post-TimeSkip opening. The latter changes the first verses of the theme song; the former, meanwhile, replaces [[spoiler: Kamina with Nia after his death]], and shows Simon tying a RedArmbandOfLeadership on his arm.
** Each of the 4 arcs of ''GurrenLagann'' has a different animation. It's most obvious between the pre- and post- timeskip openers, where the first verse of the theme song is replaced with the second, but the second and fourth arcs do have different animations than the first and third arcs.
* ''Manga/PenguinMusume'', a web anime, deserves a mention for having its opening evolve ''weekly''. What started off as simple Flash animation eventually evolved into an opening with actual animation and some pretty nifty battle sequences.
* ''Manga/KatekyoHitmanReborn'' switched up its first opening early on in its run, replacing the goofy antics of baby Lambo and I-Pin with action shots of Tsuna fighting against the Kokuyo trio -- a sign that things were going to get more serious.
* ''Anime/{{Monster}}'' uses what seems to be illustrations from a children's picture book for the first ending theme. These gradually change over the course of the series. The series [[ImageSong remix album]] contains what appears to be a reading of the actual story.
* The opening animation for ''[[OddlyNamedSequel (Zoku)]] Manga/SayonaraZetsubouSensei'' starts off as projected black-and-white film and gradually gets darker and lower-quality. Floating kanji and a border are also added to the falling sequence. Near the end of the series, the opening gains color during the falling sequence, but the film tears on the projector before getting any farther. The last episode finally has the [[http://www.youtube.com/watch?v=44r0jCd6PE4 entire opening]] in full, gaudy Technicolor with added animation.
* ''Manga/VampireKnight'''s first season does this twice despite the fact that it only runs for 13 episodes: [[spoiler:the first revision of the opening titles introduces Kurenai Maria, a second introduces her true form as Hio Shizuka]].
* ''[[VisualNovel/EfaFairyTaleOfTheTwo ef: A Tale of Memories]]'' eventually displays the pairings in the credits once the [[LoveTriangle love intrigue was solved]]. While only shown in silhouette form you can see that [[spoiler: Hiro ends up with Miyako and that Chihiro breaks from her chain which is a symbol for her having overcome, to some extent, the issues with her memory loss condition]]
* ''Manga/{{Pretear}}'''s symbolic AnimeThemeSong's standards are met in the final few episodes where the opening was touched up a bit, adding sound effects, and replacing one scene at a very specific part during the ThemeTune [[spoiler: revealing Mikage to become the Princess of Disaster and her ultimate connection with Himeno, as the former Pretear herself.]]
* ED example: Gainax anime ''Anime/PetitePrincessYucie'' changes scenes of the ending sequence to showcase the full cast of all the candidate girls finally revealed, also changing the lyrics a bit. It reverted back to the original sequence with Yucie solo in a very particular episode foreshadowing [[spoiler: Yucie's memories becoming lost in the final episode as the girls wish to cease existence, leaving her alone, for her sake. Of course, they all get better in the end thanks to the magical SparklingStreamOfTears and the PowerOfFriendship.]]
* ''Anime/GaoGaiGar''
** The original TV series changes its credits every time a new robot gets added to the heroes' lineup.
** ''[=GaoGaiGar=] FINAL'' changes its opening for ''every single episode'' to account for the changes in the storyline. The main reason they could do this was because ''FINAL'' is an eight-episode {{OAV}}, and would thus have the size and budget to do such a thing.
* Strangely [[AvertedTrope averted]] in the opening credits for the anime version of ''Manga/{{Kekkaishi}}''. The credits change to add shots of either enemies or allies relevant to whatever arc the episodes take place in, but always showcased Shishio Gen far before he even made an appearance and [[spoiler: even after he is KilledOffForReal]].
* ''Manga/TokyoMewMew'' is a strange case. Its opening actually shows all five girls from the start, whereas in the series itself they are [[DebutQueue introduced one by one]] over the course of eleven episodes (note though that the original manga shows all of them in the first chapter, albeit without revealing the names apart from [[TheHero Ichigo's]]. When the opening does change in episode twelve, it simply reveals the girls' respective Red Data Animals, which weren't kept a secret anyway, and also offers a shot of Mew Ichigo performing a new attack. Oddly, the two new aliens, Pai and Taruto, introduced just an episode later, never appear in the opening, and neither does the MysteriousProtector, so the credits' "evolution" in this case seems kind of pointless...
* ''Manga/OnePiece''
** The SoBadItsGood 4Kids opening updated the song every time a new character was introduced in the crew. By the time Chopper was in, there was almost no space in the song for another character (as the last verse said "Sanji is cooking, Chopper is doctoring"). For the very few 4Kids episodes that had Robin in the crew, all they did was add a shot of Robin into it and reverted the song back to version one.
** Oddly, most of the openings from the original Japanese version have never done this, even when they got horribly out of date. The second intro, for example, continued featuring only five members in the crew for dozens of episodes after they had added two more (Vivi and Chopper.) What's odd is that an evolved version of the second opening featuring the two of them (along with characters from the Alabasta storyline) ''does'' exist, but it never aired on television: it was only used as the intro to a OnePiece Playstation game.
** And then they went ahead and [[InvertedTrope inverted this trope]] with the third intro, which [[SpoilerOpening spoils the fact that ]][[spoiler: [[SpoilerOpening Vivi leaves the crew and Robin joins them]]]] [[SpoilerOpening a good 10 or so episodes before this happens]]. Somewhat justified in that most Japanese fans already knew this was coming from reading the manga, though.
** ''One Piece'' finally acted on this trope with the thirteenth opening, [[http://www.youtube.com/watch?v=3JMpVYO-ZHw One Day]], which, after [[spoiler: Blackbeard's new crewmembers were revealed]], [[http://www.youtube.com/watch?v=P702SE6aJfI they are all briefly shown alongside him]].
* The ending credits for the ''[[VisualNovel/{{Clannad}} Clannad After Story]]'' anime features most of the cast walking in line one after the other. When Tomoya's grandmother is introduced in episode 18, she shows up in the ending. One episode later, and his father gets added as well, in the space behind Akio and Sanae. In the final episode, Fuuko and Ushio lead the line.
** The episode title card also changes, showing the orbs of light collecting, and eventually the girl from the illusory world.
* The opening of ''Anime/MagicalGirlLyricalNanoha A's'' ends with shots of the various [[EmpathicWeapon Devices]] used in the season. When the last episode rolls around, we see the [[AnIcePerson Durandal]] and [[CreepyCoolCrosses Schwertkreuz]] take the places of [[MythologyGag S2U]] and the [[ArtifactOfDoom Book of Darkness]] in the opening due to the events of the previous episode.
* The first two openings of ''Anime/CodeGeass'''s first season added images of new characters and mecha after a few episodes (like a silhouetted shot of [[spoiler:cyborg!Jeremiah]] in the latter half of the episodes using ''Kaidoku Funou''). However, neither of R2's openings did the same thing.
* While ''Manga/YuYuHakusho'' keeps the same song for the entire run, the Japanese version changes at some point during the Chapter Black saga, and instead of showing Yusuke and his companions fighting random demons, shows shots of them fighting Sensui, some of their new powers (Kurama's yoko form, Kuwabara's Jigentoh, and Hiei's Dragon of the Darkness Flame), and a few new characters, but this opening isn't shown in the English verison of the show. The opening changes slightly for the Three Kings Saga in both versions, as it shows Yusuke falling out of Raizen's tower, Yomi and Mukuro, and some of the former Dark Tournament contestants.
* ''VisualNovel/UminekoNoNakuKoroNi'''s credits change the initial portrait in the opening every five or so episodes to reflect the change in arcs. And then the third arc started, and the opening underwent a much larger transformation.
* The credits of ''Manga/GAGeijutsukaArtDesignClass'' not only cycles between [[RearrangeTheSong 5 versions of the ending song]], but also has steadily changed over the course of the series with the girls getting older and their activities changing.
* In ''Manga/KOn'', upon the addition of Azusa to the Light Music Club, she is super-imposed into several scenes, as well as her very own character introduction, in the OP. Yet strangely, the keyword here is 'several', since she doesn't appear together with the other 4 club members in ''all'' the scenes where all the other 4 club members are present. Also, the opening theme song is modified slightly, with additional guitar bits and one more backing vocal mixed in.
* ''Manga/{{Needless}}'' has a small one in the second intro -- a shot of Simeon's fourth strongest removing their mask cuts away before you get to see the face until the big reveal happens a few episodes later.
* The many Japanese ''Franchise/{{Transformers}}'' shows are fond of this trend, updating whenever new characters are shown in the series, and typically having at least two opening videos per series.
** Special recognition goes to the ''[[Anime/TransformersCybertron Galaxy Force]]'' series, which in addition to constantly evolving opening credits as new characters get added to the cast also features evolving end credits throughout the series. The first half frames clips from the episode just shown as flashbacks of one of the main characters, while the second half shows all the cast with characters who have yet to show up shown in silhouette only.
** Also, the Japanese opening for ''WesternAnimation/TransformersAnimated'', in which in the first opening, we see [[BigBad Megatron]] in his Cybertron mode attacking the Autobots with the help of the Starscream clones, while in the second, they now use the second verse of the opening theme song not to mention the fact that the aforementioned animation with Cybertron-mode Megatron and the Starscream clones has been replaced with a new animation showing Megatron in his Earth mode attacking the Autobots with the help of two Soundwaves (the second Soundwave is a different color), two Blackouts (the second Blackout is supposed to represent [[Film/{{Transformers}} Grindor]]), and Swindle.
** They're basically a ''reversal'' of the usual intent of this trope. Instead of revealing characters one by one, characters who won't be seen for a ''very'' long time appear, and some one-shot characters are given screentime to make you think they were as important as Prime himself. Both openings are a thing of beauty, with major EarWorm songs, but they're ''on crack'' when held up against the actual events of the show.
** Just to go into the already-mentioned examples: the black-and-red Soundwave represents ''[[spoiler: the real Soundwave's virtual world avatar]]'', not another character. Also, ''Grindor is not in TFA '''at all''''' [[note]]Okay, ''long'' after the fact, a Grinder (with an E) who is colored nothing like Blackout (unlike Blackout's 100% identical twin in the opening) does appear in a ''card game.''[[/note]] and the two Blackouts are perfectly identical (unlike movie Grindor, a blue-gray repaint of movie Blackout) so he ''is'' a second Blackout, not Grindor. In the actual show, Blackout appears for all of 20 seconds in the opening scenes of the third season premiere. He gets one line. He doesn't even appear in the virtual world alongside most of the rest of his team. Also, Swindle is a solo operator who'll sell arms to ''anyone,'' and is only considered a Decepticon because [[MerchandiseDriven his toy's gotta be sold as something, and he sure ain't no Autobot]], and makes little sense as someone to have alongside Megs. This is by no means the full extent.
* ''Anime/AngelBeats''
** The ending credits evolve with changes in the cast or relations among the characters, such as the removal of characters who move on, or a character who was revealed in that episode to be buff going [[FanService shirtless]] in the credits.
** The opening credits evolve as well. Like the ending credits, characters are added or subtracted from the opening as they are introduced to the cast, or they move on. Both the opening and ending of the final episode credits include ALL of the characters, even those who moved on very early in the series.
* The opening for ''Anime/DragonBallKai'' swaps out old footage for new action scenes whenever each new baddie shows up in the story. At first it focuses primarily on Vegeta and Frieza's men, then exclusively on Goku's fight with Frieza, and then changes to include the entire group fighting the Androids.
** This is far from the first time ''Manga/DragonBall'' has used this trope. The original opening, ''Mystical Adventure,'' changes around the time of [[KnightOfCerebus Piccolo Daimao]], while the ending changes footage four times (the American release only uses one version for each throughout). Z's first theme, ''Cha-La Head Cha-La'' changes around the arrival of Vegeta and Nappa, and again at the beginning of the Artificial Humans arc.
* The anime of ''Manga/MahouSenseiNegima'' does this with the opening. Apart from the song change every 5 episodes or so, the girl's bathing suits occasionally change colours. ''Negima!?'' plays the trope straight in the ending. The further the show goes, the more characters appear at the bottom-right and play music instruments. A CrowningMomentOfFunny happens when Setsuna joins in, since she sleeps in halfway into the song, only to wake near the end and become red like a hummer out of shame.
* Very common in the ''Anime/PrettyCure'' franchise:
** The second half of ''Anime/FutariWaPrettyCure'' had the ending changed to feature the new QuirkyMinibossSquad instead of the old one and to include Pollun along with Mipple and Mepple.
** ''Anime/FutariWaPrettyCureSplashStar'''s opening changed to include [[spoiler:Cure Bright and Cure Windy]].
** ''Anime/YesPrettyCure5'' added [[spoiler:Milk and her [[MidSeasonUpgrade upgrades]]]] after they appeared.
** ''Anime//FreshPrettyCure'''s opening added [[spoiler:Cure Passion]] and [[EvolvingMusic remixed the theme]].
** ''Anime/HeartcatchPrettyCure'' had three openings, the second adding [[spoiler:Cure Sunshine]] and the third added [[spoiler:not just Cure Moonlight, but Coupe in the battle scene as well]].
** ''Anime/SuitePrettyCure'' adds [[spoiler:Cure Beat]] and, like ''Fresh'', [[EvolvingMusic remixed the theme]].
* The final episodes of ''Anime/SoraOKakeruShoujo'' involve Leopard gaining the final parts needed to bring him to full strength. The openings of these last episodes, as a result, show Leopard with these upgrades attached in the final seconds.
* Being by Creator/StudioSHAFT, it shouldn't be much of a surprise that ''Anime/PuellaMagiMadokaMagica'' does this. Mostly pretty small changes, though. The only one the average viewer is likely to catch is Kyouko and Homura finally being added to the group shot in episode 10.
* The first opening of ''Anime/YuGiOhZEXAL'' does this during the part of Yuma being joined by his friends during a walk. Initially it just Kotori and Tetsuo (''ENG:'' Bronk). After the episodes that introduced them, Takashi (''ENG:'' Casell), Tokunosuke (''ENG:'' Flip) and Cathy are shown joining in as well.
* The Second opening of ''Anime/YuGiOh5Ds'' changes in episode 48, to reflect [[spoiler:Aki and Jack's designated Signer opponents and Ruka recieving Ancient Fairy Dragon]].
* The ''Manga/{{Bleach}}'' ending theme ''Haruka Kanata'' gives the spotlight to a different character every episode.
** The same thing was done before with ''Houkiboshi'', which gives the spotlight to one of the captains and their lieutenant (and sometimes, other members of that Gotei 13) each episode that ending theme was used.
* ''[[Anime/{{Persona 4}} Persona 4: The Animation]]'' has one of its credits animations, starting from the second episode. The credits sequence involves several Persona cards that are glowing white on one side. As the show progresses, the [[TarotMotifs Tarot]] symbols start appearing instead of the blank space.
* Both season of ''Manga/{{Working}}'' have characters added to the opening during the episode they appear in. For the first season, it was just Yamada, but for the second season Haruna, Youhei and Mizuki Mashiba and Kirio are all added to the opening by the seventh episode.
* ''Anime/OutlawStar'' has a subtle change starting with episode 18: The shot of the three female leads on a bed, instead of having them all facing different directions, shows Aisha and Suzuka holding Melfina, who's looking at the camera and smiling.
* ''Anime/TheIdolmaster'': All the ending sequences are completely different.
* Played with for the posters of the ''Anime/RebuildOfEvangelion'' series, with each poster appearing almost exactly the same, except with each new poster, new characters are added. For example, the poster for ''Evangelion 1.0'' features Shinji, Rei, Toji, Kensuke, Hikari, and Kaworu. The poster for ''Evangelion 2.0'' features everyone from the first poster, plus Asuka and Mari.
* ''LightNovel/{{Inukami}}'' has its endings show where the cast is currently living.
* The first opening and ending sequences in ''Anime/EurekaSevenAo'' change the color of [[LockedIntoStrangeness Ao's hair]] and the Nirvash in sync with their actual color changes in the series. As the series progresses the opening also adds an additional shot of Eureka - first with her back to the camera, then turning to face it.
* End credits in WolfsRain have a white wolf running through landscape that changes slightly with each episode. The last one is particularly interesting.
* In ''Anime/GirlsUndPanzer'', the ending rotates through different girls and the tanks they operate. And in episode 5.5, it shows four of them side by side.
* ''VisualNovel/LittleBusters'': Near the beginning of the first set of credits, there's a shot of each of the childhood friends standing together. In episode 15, after the last main character finally joins the Little Busters for real, the shot is changed to one of all of the characters standing together. Also, while the original credits were pretty upbeat, the new credits add in some darker shots of Kud and Haruka looking sad, reflecting the way the story starts off seeming bright and happy [[CerebusSyndrome and then slowly goes downhill.]]
* The end credits for the 2012 ''Manga/JoJosBizarreAdventure'' anime, which features a slow-pan over an Aztec mural filling with blood (Part 2 continues where Part 1's credits left off,) while shots of the characters appear in the foreground, with new ones appearing when new characters are introduced and old ones disappearing or updating when characters die, fade from relevancy in the current events or undergo a drastic change (like normal Dio becoming vampire Dio, or Stroheim becoming a cyborg.)
* In the third season of ''Manga/TheWorldGodOnlyKnows'', the ending theme is sung by the girl who is revealed to be having one of the Goddess (except for [[spoiler: Tenri]] which is already revealed on the [[spoiler:Tenri Arc OVA]]) in that episode (except for Episodes 1,7 and 8 which have no ending themes and Episode 9 which has a different ending theme altogether)
* In ''Manga/WitchcraftWorks'', as new characters are introduced, they get added to the scenery that strolls past about halfway through the song. Some of them join the Tower witches, while others join the Workshop witches group, depending on their affiliation.
* ''Manga/AkumaNoRiddle'' has a completely different ending for every episode, each corresponding to one of the students of class Black.
* ''Anime/KillLaKill'''s second opening changed to show the characters' various wardrobe changes.
* The cards displayed in the endings of ''Manga/GochuumonWaUsagiDesuKa'' anime vary slightly, and adds more girls as they're introduced in the show.
** In episodes 8 and 9, it switches from blue to red cards about halfway through, and displays multiple cards at once instead of one at a time. Additionally, at the end of 8, instead of Chino's father and Tippy at the end, it's Aoyama and Tippy. He doesn't say anything, and instead just turns around and notices it's not his son.
** In episode 10, it reverts back to the original ending, though it doesn't always shows face cards initially. A couple of cards then drop on top of it until one of the correct cards is seen, then the rotation begins again, until a set of Royal Straight Flush with two Jokers (containing all girls) is completed. Chino also pops up at the next episode preview when Tippy mentions wanting a quiet Christmas to announce they were throwing a Christmas party next episode.
** During episode 11's ending, the red and blue cards are shown simultaneously, along with the face of the cards on a third deck. After a short while only one card is seen, and it rotates between the face cards with the various girls on them. Additionally the background is Christmas-themed and switches images occasionally.

[[folder:Films -- Live-Action]]
* ''Film/{{Frankenstein 1931}}'' (1931) lists the cast members in the opening credits... except for the Monster, who is billed with a question mark where the name should be. It's only ''after'' the film, when the cast is listed again, that we learn it was Boris Karloff.
** They did a similar thing with [[spoiler:kevin spacey]] when he played the serial killer in ''Film/{{Se7en}}''
* ''Film/StarTrekIIITheSearchForSpock'' did not include Leonard Nimoy as Spock in the opening credits, unlike every other movie and episode. This was to avoid giving away Spock's eventual resurrection and fast-aging (so that he could be played by Nimoy again). It worked because so many people thought Nimoy hated playing Spock, as he allowed him to get killed off in ''Film/{{Star Trek II|The Wrath of Khan}}'' and wrote a book called ''IAmNotSpock''.
[[/folder]]

[[folder:Live-Action TV]]
* ''TheWestWing'''s credits changed not only to reflect the show's different casts, but also their evolving job titles. Fans have even gone so far as to [[http://www.youtube.com/watch?v=hh97y5Sqy0o&feature=related edit together very convincing credits for a hypothetical eighth season]], which happen to have the very sweet touch of Bradley Whitford being introduced at the exact moment John Spencer used to be, as Whitford's character would be taking up the same position as Spencer's. Plus, it works out right alphabetically.
* ''Series/KamenRiderRyuki''
** The series shows a few quick glimpses of the content of the episode at the beginning of each title sequence. ''[[Series/KamenRiderFaiz Faiz]]'' and ''[[Series/KamenRiderDenO Den-O]]'' went on to show similar preview clips in their opening sequences. ''[[Series/KamenRiderKabuto Kabuto]]'' shoehorned in new opening clips when [[spoiler:Gatack]] was introduced, and so did ''Den-O'' for [[spoiler:Zeronos]]. But for a classic example of this trope though, look no further than ''[[Series/KamenRiderBlade Blade]]'': it entirely changed (including a brand new theme song) when [[spoiler:Leangle]] showed up.
** Of course, the AMV for Opening 1 still features four Riders.
** ''Series/KamenRiderDecade'' evolved in three different ways: first, clips of Diend are added after his introduction, second, the opening narration is slightly changed when it becomes apparent that more worlds beyond the Heisei era Riders' will be visited and third, clips from the first movie (mainly from the really big battle at the end of it, and often spoiling several [[CrowningMomentOfAwesome Crowning Moments of Awesome]] found there) are shoehorned in upon episode 26, the scenes changing each episode. [[spoiler:The abrupt switch to the regular opening sequence for the final episode hints at it not being the true finale of the series (The second movie serves that purpose).]]
* The ''AmericanGladiators'' revival adds the new gladiators to the title sequence only after they've actually appeared on the show. In addition, gladiators have been removed from the credits due to injury or being part of the reserves.
* On ''Series/{{Angel}}'', new images of Fred as Illyria were not added to the credits until after the characters [and the audience] discovered they couldn't get Fred back.
** Additionally, in season 1 Wesley didn't appear in the credits until after he started working with Angel and Cordelia. His first episode still had Doyle in the credits [[spoiler:despite the fact that Doyle had already died in the previous episode.]]
* ''Series/BabylonFive'': The second season modified its opening after the third episode once a surprise is revealed. It also constantly updated its credit captions throughout the run to reflect change in character status, such as promotions. Unfortunately, the DVD release of the second season did not maintain these changes, and thus a new viewer could be spoiled if watching the opening credits on the first two episodes. They also did a variant credit sequence for the episode "The Corps Is Mother, The Corps Is Father", reflecting the episode's focus on Psi Corps.
* ''{{Series/Battlestar Galactica|Reimagined}}''
** Katie Sackhoff's name was removed from the opening credits after her character's death.
** Additionally, they update the survivor count in the introduction every episode.
** There is also a variant opening with different clips and no survivor count during the New Caprica arc possibly to hide how bad things had really gotten on New Caprica, so the revelation to the characters themselves in show would have more impact, or more simply because the governing president wasn't updating the white board.'
** The Cylon part of the opening ("The Cylons were created by man...") also evolved over the course of the series. Season 1 used a longer version than the other seasons with lines focusing on Boomer's status as a "sleeper agent." Season 4 changed to a whole new wording focusing on the Final Five (which also evolved as the other characters learned their identities). ''The Plan'' went back to the original wording, but it was done as a voiceover by the various Cylon characters. They also updated the footage in each season to reflect which Cylons were known to the audience.
* Miller Boyett shows did this out of necessity; in addition to reflecting cast changes, reshoots were done to reflect character development.
* Especially common in Reality Competition shows:
** ''Series/{{Survivor}}''
*** In the Guatemala season, two extra contestants (returning from the previous season) were added to the opening after being introduced post-opening in the first episode. The China season was the first of several to change its titles post-merge to show who was still competing and who was on the jury. Micronesia had eliminated contestants being removed from the opening, along with implementing the China-style post-merge titles.
*** Further, the team colors are altered in the opening credits to prevent viewers from seeing who changes teams. Since this is the halfway point of the season, it also allows viewers to know who's safe for the first half of the season.
** ''BigBrother'' does a version of this as well; ejected housemates have a clip of them leaving the house replacing their appearance in the intro.
** Every season of ''TheMole'' (except the first possibly) updated the credits each episode. The status of players who had left the game was displayed when their name and picture appeared in the credits.
** ''Series/TheAmazingRace'' revises its opening titles around the sixth episode in each season. Early on each team has an "in their home environment" shot before a turn-to-the-camera-and/or-the-camera-pans-to-you portraits, both filmed in a single session (Sometimes just the same shot from two angles). In the revised credits each team's first shot is from one of the first episodes. Teams eliminated early are usually shown in their fatal challenges, while the continuing teams at that point team are shown doing other challenges or in transport - occasionally also a CrowningActOfFunny.
* ''PowerRangers''
** The title sequences for the shows change after a bit to include the new SixthRanger, Megazord, Battlizers, etc.
** The season that holds record for fewest opening changes is ''[[Series/PowerRangersLightspeedRescue Lightspeed Rescue]]'', at a mere ''one'' change (only adding its SixthRanger, and nothing else), but some are ''always'' changing. ''Series/PowerRangersOperationOverdrive'' changes to add a new Ranger, to update Miratrix's hairstyle, to add every new Megazord formation, to add a SuperMode for Mack, and... sometimes just because they feel like it, it seems.
** ''Series/PowerRangersInSpace'' shows only four Rangers in its first opening and continues to feature Divatox from ''Series/PowerRangersTurbo'' as if she'll be remaining BigBad, the better to keep the arrival of new Ranger Andros and new BigBad Astronema hidden until their debut later that episode.
** ''Series/PowerRangersLostGalaxy'' has several, due to ''any character who isn't in the episode'' being left out, as well as permanent new characters being added. (The exception being Kendrix's departure, due to the actress' leukemia. She was left in the opening for the duration.)
* Each season of ''TheWire'' uses a different version of the theme song, "Way Down in the Hole", and a different montage during the opening credits, which reflect the mood of each season. The montages integrate clips from previous seasons and out-of-context clips that become clear much later on.
* The opening titles to the first episode of ''TheWorstWitch'' did not feature Mildred and her friends. Instead we saw the shots we usually see of all of the other witches (as well as one of a witch descending in front of the gate which didn't end up in the proper opening). The school song (used as the show's opening theme) was also not played and instead an instrumental BGM was. It was from the second episode onward we saw Mildred and her friends (bar Enid, who wasn't added until after her debut episode) flying on broomsticks and the school song was used as the opening theme.
* ''Series/StarTrekDeepSpaceNine''
** The first episode opening does not show the wormhole, because it's only discovered in that episode.
** Later seasons replaces the runabout with the ''Defiant'' after it was introduced at the beginning of season 3.
** Starting with season 4, the original arrangement of the opening theme was replaced with a more ominous version, possibly to reflect on the darker turn the series had taken with the introduction of the Dominion MythArc.
* The opening credits for the pilot episode of ''Series/{{Charmed}}'' did show the sisters casting a spell, but not their individual powers. Plus, the title sequence was altered regularly to only show actors who appear in the episode.
* ''Series/ICarly'' has a new credit sequence every season after the second, and adds casts members as they are introduced.
* Australian soap opera ''{{Neighbours}}'' has as it's title sequence a montage of all the main characters that are in the show at that time (not just the characters who show up in the storylines for that particular episode, though which storylines will be continued in a given ep is spoiled by the "previously on" catch-up before the title sequence). Whenever a character or characters join the main cast or leave/die, the title sequence montage is updated to reflect this...though not always immediately.
** In some versions of its title sequence, rival Australian soap opera ''HomeAndAway'' would also use evolving credits showing the current main cast. Again, just because a new arrival isn't on the credits, doesn't mean that they're not staying long...they might just not have been added to the credits quite yet.
** By contrast, British soap operas don't tend to use title sequences that show the show's characters. CoronationStreet has an establishing shot of the titular street, Eastenders has a title screen of a map of the London area, and Emmerdale has establishing shots of the rural setting. ''Series/{{Hollyoaks}}'' however, ''does'' show images of its main cast. Unfortunately they only update the credits every so often, and with Hollyoaks being a quiet suburb with the mortality rate of a Mafia blood feud, it means that on occasion a good proportion of the characters in the montage are currently dead. Later on it gets updated more often but still doesn't change immediately after a character change.
* ''Series/{{Fringe}}'''s opening sequence was originally a series of fringe science-related words flashing on a blue background, some of which would relate to that season's themes. The season two finale, which took place on the "other side", introduced a new sequence with a red background; during the next season, the color of the intro indicated on which side the episode took place. The season three finale was set 15 years in the future and featured a silver background. Season four brings us a yellow sequence, signifying either [[spoiler:the new Peter-less timeline]] or [[spoiler:the fact that the two universes are bridged]]. Finally, the fifth and final season uses a cold blue sequence, and ditches the fringe science terms for [[spoiler: words like "freedom" and "private thought" for things the conquered Earth has lost]].
* ''Series/GameOfThrones'''s opening sequence, a sweeping flyover of a map of Westeros, complete with [[ClockPunk Clock Punk]]-themed cities and castles, changes from episode to episode, depending on where members of the main cast are at any given time. Major changes to locations are also accounted for: from season three onward [[spoiler: Winterfell, which has been burned down, billows clouds of smoke.]]
* Being a LongRunner that [[TheNthDoctor swaps out its main character as a matter of course]], the credits for ''Series/DoctorWho'' have gone through ''[[http://www.youtube.com/watch?v=sjMR98ODhS4 many]]'' changes.
** The most extreme example has to be the credits sequences of Series 7.1, which grew progressively darker with each episode. Also, during that same series, the show logo gained unique textures in keeping with that episode's plot (e.g. for "Asylum of the Daleks," the logo was covered with Dalek bumps).
* As doctors came and went from the 4077th, ''Series/{{MASH}}'' inserted and removed its characters from the scramble to get the wounded in the opening credits. The final shot of the credits originally showed Hawkeye and Trapper riding on the jeeps headed back to the camp. After Wayne Rogers left the show, they kept the shot, but reframed it to crop Trapper out.
** For Season Four, the shot of Trapper scurrying to a chopper is removed, and replaced with a shot of B.J. rushing towards the chopper, from a distance, making him somewhat indistingushable. Afterwards, a clearer of shot B.J. helping casualty from the chopper's rumble seat is used for Seasons Five and Six. Similarly, the same shot was used for the first couple of episodes for Season Seven, before we see on the show itself that B.J. now has a mustache; afterwards, a close up of a mustachioed B.J. is used in the opening credits for the rest of the series.
* In ''Series/{{Soap}}'' the "family photo" at the start of each episode would change whenever more characters became part of the family or when some left/died.
* The credits for ''NYPDBlue'' showed Dennis Franz second after the somewhat younger actors (David Caruso and Jimmy Smits) who played his partner. He was moved to first in the lineup when Sipowicz was partnered with detectives played by the ''considerably'' younger Rick Schroeder and Mark-Paul Gosselaar.
* ''Series/BreakoutKings'': After Charlie's death Ray is alone and his badge now sports the black band used for mourning a fallen officer.
* The second season credit sequence for ''Series/ProjectUFO'' was significantly changed from the first. While justified in part by the recasting of the "lead officer" role, the cast members weren't actually shown in the first season credits. The new credits include 40 seconds of spaceship special effects shots plus footage of the leads taking off in an Air Force fighter jet. It's all more suggestive of a science-fiction action-adventure show than what the show actually was -- a "just the facts" procedural in which, as in real life, the Air Force never found conclusive evidence of extraterrestrial visitors.
* This happened to the opening credits sequence for season 2 of ''Series/{{Grimm}}'', such as with the inclusion of Captain Renard's GameFace following its much-anticipated reveal during episode 2.
* ''TheBigBangTheory'' ends its opening sequence with a brief clip of the cast having take-out together. The original was taken before the show [[EarlyInstallmentWeirdness really established itself]] and thus has a few unusual quirks unique to the pilot such as: Penny has a much different hairstyle than normal, Raj is wearing a reddish ball cap that is never seen again and the white boards filled with equations are displayed prominently (they show up from time to time, but are not a mainstay of the apartment set design). The third season had a new one that reflected the series slightly better and the fifth season added a new shot where Penny is taking a really big bite. The sixth season finally includes the latest cast additions Amy and Bernadette.

[[folder:Video Games]]
* ''VideoGame/HitmanBloodMoney'' has a title screen showing an audience inside a church. The audience changes as you progress through the missions, but with members disappearing as you kill them.
* In ''[[VideoGame/MetroidPrime Metroid Prime Trilogy]]'' has the main menu set inside Samus' ArmCannon. After choosing a game and save file to load, the camera zooms out while Samus turns and shoots as transition into the game. The armor she's wearing while doing this is the same as the suit she's currently wearing in the save file you loaded. In ''Corruption'', it even has different models of Samus' PED Suit as it gets more and more corrupted as the game progresses.
* ''VideoGame/SuperSmashBros.''
** The credits of the first two games won't show staff that was only involved with creating characters\locations that haven't been unlocked yet. Also, if someone worked on, for example, Mario and Luigi, it would say they worked on Mario and ???? if Luigi's locked.
** The first scene in the opening sequence of ''VideoGame/SuperSmashBros. Brawl'' (both the quick pass by the group and the shot of them standing on the cliff) gets increasingly filled with secret characters as they get unlocked. This is carried over from the N64 game, where the final scene before the title screen is the silhouettes of the secret characters, that are revealed as they are unlocked.
* ''Franchise/WildArms''
** In ''VideoGame/{{Wild ARMs 2}}'', ''3'' and ''4'', whenever you load from a save it plays an opening credit sequence, and in ''VideoGame/{{Wild ARMs 3}}'' whenever you save and quit it plays a closing sequence. The sequences change based on how far in the game you've gotten so far.
** The original and ''Alter Code F'' have one generic clip used throughout the game. ''Wild [=ARMs=] 2'' and ''4'' have two different clips, which generally appear halfway through the game (on the second disk in the case of 2). ''Wild [=ARMs=] 3'' goes mad with this though, having no fewer than five variations of the opening credits, not counting the different songs which also play in the background which evolve independently of the video footage. Though to be fair the versions were mostly the same, all that changed was a bit in the middle that showed the current villains for that point in the game.
* The technical limitations of ''Wrestlemania 2000'' let you play with this as it used in game models and costumes during its intro, which could be edited.
* ''VideoGame/MarvelVsCapcom2'' had an AttractMode that had all characters standing in a line with those yet to be unlocked merely as silhouettes.
* In ''VideoGame/FireEmblem: [[VideoGame/FireEmblemJugdral Seisen no Keifu]]'', each time the player finishes a playthrough, a new set of battle and story sequences are added in the opening credits. You need to complete the game 15 times to unlock all of them, and the most interesting of them storywise (such as [[spoiler: Levin being killed by Manfroy in battle, then resurrected/possessed by the Wind God Holsety]]) are of course the last ones you get.
* In ''VideoGame/SilentHill1'', the opening movie changes when you finish a playthrough with a Good+ End: [[spoiler:in the part where Harry and his wife find baby Cheryl, Harry's wife is swapped with Cybil]].
* In ''[[VideoGame/SoulSeries SoulBlade]]'', completing the game with all characters in Arcade Mode changes the title screen / main menu from a bland gray screen from a picture lining all characters.
* Weirdly enough (and showing how much the Japanese ''adore'' this trope), you can do this yourself in the game ''Fire Pro Wrestling Returns'', during a short video that flashes by the entire ''massive'' roster, and any created wrestlers you add will show up exactly where you put them, relative to roster position.
* For a extremely rare case of a console's BIOS pulling this trope, look no further than the PlayStation2's booting screen. Turning on the system with a completely empty memory card would show you nothing more than "Sony Computer Entertainment" in a dark blue void. Subsequently, the memory card will log each seperate game you play on the system in a save file called "Your System Configuration", which has the effect of adding one white block per game on the startup screen. Furthermore, the more you play a specific game, the more its designated block will grow in height. And as you might have guessed by now, deleting the "Your System Configuration" file will devolve the screen back to an empty void.
* In ''VideoGame/DeadSpace2'' the further the player's progress in the main single player mode is, the more [[spoiler:pieces of the Black Marker congregate and take shape in the main menu. Completion of the game results in a fully assembled Black Marker drifting aloft the menu.]]
* ''VideoGame/CallOfDuty'' changes its menu image as you play farther in the campaign -- at the start, it features an M1 Thompson; when you get to the British missions, it instead features a Lee-Enfield; and for the Soviet portion, it features a Mosin-Nagant.
* ''VideoGame/JetForceGemini'' has a title screen that changes as you unlock more characters and levels.
* ''VideoGame/KnightsOfTheOldRepublic 2'''s menu screen features a Sith Lord surrounded by ominous fog. ''Which'' Sith Lord depends on who the [[TheManBehindTheMan currently revealed]] BigBad is. Bottom out the KarmaMeter, and it will be [[PlayerCharacter The Exile]] [[EvilerThanThou him/herself]]
* In ''VideoGame/AngryBirds'', after a bird has made its first appearance, it will be seen leaping across the title screen. Upon completing an episode, an item related to the episode will be flying across the title screen as well. If you get [[HundredPercentCompletion all stars in an episode]], its respective item will adopt a star motif. Finally, the background of the title screen will change depending on which level you last played (if it is a level from "The Big Setup", however, the construction background won't appear).
* ''VideoGame/YoshisIsland'' features a [[EvolvingMusic thicker instrumentation for the title theme for every world you unlock]]. And when you unlock that last world...the whole rotating world's appearance changes too.
* In ''VideoGame/SonicUnleashed'', the main menu is a shot of Earth. Prior to starting the game, the planet is intact, but returning to the screen after the intro instead shows the planet shattered. As the player progresses through the game & restores the Earth, the state of the planet is reflected on the main menu.
[[/folder]]

[[folder:Visual Novel]]
* In ''[[VisualNovel/TokimekiMemorial Tokimeki Memorial: Forever with you]]'', if you complete a playthrough getting [[VictoriousChildhoodFriend Shiori's]] love confession and [[GoldenEnding Ending]], the part of the opening demo where Shiori's lips are moving with no sound coming out, has now the sound added, revealing that she's saying : "Suki desu" ("I love you").
* The title screen for [[VisualNovel/KatawaShoujo Katawa Shoujo]] is initially blank but for the menu and the title. However, in every character's route, there is sketch that marks the opening of a new act, and the sketches slowly fill the title screen.
[[/folder]]

[[folder:Web Animation]]
* As its cast evolved (as characters were often introduced out of nowhere), the opening sequence to ''WebAnimation/BonusStage'' would change slightly between seasons to accommodate new characters, at one point adding a few bars to the song itself for Rya, Jessica, and Evil, until the theme song just changed entirely...twice.
[[/folder]]

[[folder:Web Original]]
* ''WebVideo/TheTwilightChronicles'' features new opening credits for every episode, featuring only the series regulars who appear in that episode, as well as that episode's guest stars.
* ''WebVideo/AtopTheFourthWall'' will change its opening sequence in its annual looks at ComicBook/TheCloneSaga, including updating the footage used in some areas!
** Linkara's other series, ''WebVideo/HistoryOfPowerRangers'' has received updated opening titles to add the ''[[PowerRangersSamurai Samurai]]'' and ''[[PowerRangersMegaforce Megaforce]]'' teams after both seasons began airing.
* ''WebVideo/SteamTrain'' debuted a new intro for its one-year anniversary, where Ross is conducting the train and Danny, Arin, Barry and Suzy are all passengers; compare this to the original intro which only featured Ross and Danny (with alternate endings if Arin was involved as well). The new intro is more in line with Ross' vision of the show, where he'd host and other GameGrumps members would come in and out depending on the game (although Barry and Suzy were only involved in four-player ''Steam Rolled'' series, save for four holiday-themed episodes for Barry).
[[/folder]]

[[folder:Western Animation]]
* ''WesternAnimation/TheSpectacularSpiderMan'' added Mary Jane to the titles after her inevitable "jackpot" introduction. Also, during the second season, the intro becomes DifferentInEveryEpisode to indicate which supporting characters will play major roles.
* After nearly twenty years of ArtEvolution, ''TheSimpsons'' finally updated the opening when the show switched to HD. It's essentially the same, but with some added background material that includes {{Continuity Nod}}s and a bunch of characters introduced after the second season. Which itself is OlderThanTheyThink: the show's first season had an opening different from the one used for the next 18 seasons.
* ''WesternAnimation/AvatarTheLastAirbender'' has an opening that involved a character's belief that the Avatar was still alive somewhere, with her narrating. This opening lasted for one episode before she found Aang, the new Avatar, about halfway through the first episode. Starting with #2, it kept the newer opening with some minor edits, seeing as the narrating character now knows of the Avatar's existence. It then fails this trope completely, as Katara continues to say "Aang is a long way from rescuing anybody," even after he has rescued many people and cities and even a king or two. She even says this at the beginning of the final episode, when Aang is ''in the middle of a fight'' to save the world.
* Midway through the fourth season of the second ''[[WesternAnimation/TeenageMutantNinjaTurtles2003 Teenage Mutant Ninja Turtles]]'' cartoon, the show's opening was altered to take out scenes featuring the old vehicles (which had been destroyed) and Foot Ninja (which had been redesigned), replacing them with newer versions of each. Also, the scene featuring the Shredder, which had been altered to reflect his ultimate defeat, was altered yet again to reflect Karai's debut as his replacement.
** Both of the other cartoons have done so as well. The [[WesternAnimation/TeenageMutantNinjaTurtles1987 80's cartoon]] featured a completely brand-new animated intro in the middle of the fourth season when the show went from syndication [[ChannelHop to]] Saturday mornings on CBS. Meanwhile the [[WesternAnimation/TeenageMutantNinjaTurtles2012 2012 cartoon]] has incorporated new villains into the intro, as well as Casey Jones who can be see in the background at one point.
* The opening of ''WesternAnimation/Ben10AlienForce'' showed [[RealityWarper Alien X]] in silhouette until after his introduction in the season 1 finale "X = Ben + 2". Though Alien X's actual appearance is just that of his silhouette [[StarSpangledSpandex pasted over a space background]].
* Likewise with the original ''WesternAnimation/{{Ben 10}}'' series, after Ghostfreak leaves the Ominitrix and Ben gains Cannonbolt. The alien roll call takes out the former and puts in the latter.
* ''WesternAnimation/{{Wakfu}}'': The second season's credit had a character added to the heroes' group after 4 episodes, when it was revealed [[spoiler:he was BackFromTheDead]].
* ''WesternAnimation/JackieChanAdventures'' would change its credits with the season's story arc, but only in certain parts. Most of it would be unchanged, but Jade would either be casually tossing a [[MacGuffin talisman or magic puzzle box]], and Jackie would conclude by punching out the more threatening of the whatever version of the Enforcers were featured (Tohru, then Hak Fu, then magically altered Enforcers). Look close as the series progresses and you'll see more.
* Similar to ''The Simpsons'' example above, ''WesternAnimation/KingOfTheHill'' re-animated their opening sequence EXACTLY as it was when the show started. Even Buckley was kept in.
* After a few seasons, ''WesternAnimation/AmericanDad'''s opener changed almost entirely. Stan leaves the house differently, the rotating newspaper gag is replaced with Roger stowing away in a different costume each week (though often previously seen in the series), and his stance in front of Old Glory outside the CIA changed from a presentational gesture to a salute.
* The intro to ''WesternAnimation/AvengersEarthsMightiestHeroes'' has a shot of the team that varies depending on how many members the Avengers have at the episode's start.
* In ''WesternAnimation/AlvinAndTheChipmunks'', after switching animation studios in season 6, the title of the show was changed to ''The Chipmunks''. Initially, clips from the "Girls/Boys of Rock and Roll" scene from TheMovie were used, then shortly afterwards a newly animated sequence was introduced featuring the Chipmunks coming out of a limo and getting their makeup done. Both featured a [[EvolvingMusic newer]], [[AutobotsRockOut harder rocking]] version of the theme, which was also used with the original opening animation on syndicated prints of season 6 episodes.
* With the start of a new season of ''WesternAnimation/TheBackyardigans'', some clips of the opening, previewing certain episodes of the previous season, are changed to preview episodes of the actual season.
* ''WesternAnimation/SouthPark'' gradually added new characters, objects, and events to the opening over the first four seasons. Eventually they switched to a new opening consisting of clips from the series and a group shot at the end that was updated every season.
** Also, Kenny's ([[TheUnintelligible muffled]]) line in the opening theme changes every few seasons.
* Each season of ''WesternAnimation/TheVentureBrothers'' has a subtly different opening. Some episodes that focus on specific characters have special openings, like the season two and three openers.
** They also reflect evolving character features, most notably Hank and Dean's divergent style selections at the start of Season 4.
* ''WesternAnimation/DuckTales'' initially only had Bubba Duck appearing in new clips for the second season version of the intro. After the 5-part arc that introduced Bubba there was another 5-parter that introduced Fenton Crackshell/Gizmo-Duck, and subsequently there was another new version of the opening that featured clips of Fenton as well.
* When ''WesternAnimation/FamilyGuy'' switched to HD in their ninth season, the opening sequence was reanimated to match the updated animation style. Also, the random extras in the chorus line were replaced by recurring characters.
* In ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', the opening was changed in season 2 episode 3 to include [[PromotionToOpeningTitles the Cutie Mark Crusaders, Big Macintosh, more background ponies]] and the Friendship Express Train, as well as an additional appearance of Canterlot and the mountains in the background. The opening was changed again starting with the season 4 premiere; Twilight Sparkle has wings, [[HeelFaceTurn Discord]] is seen peeking out from inside Fluttershy's cottage, Princess Luna is beside her sister Princess Celestia when she receives a letter from Twilight, and the picture of Twilight and her friends enclosed in said letter is seen being taken by [[EnsembleDarkHorse Photo Finish]] and includes [[CrowdedCastShot Spike, the Cutie Mark Crusaders, Snips and Snails, Mr. and Mrs. Cake, Big McIntosh, Granny Smith, Mayor Mare, and Zecora]].
* ''WesternAnimation/RobotChicken'' used the same opening for 5 seasons (with a special ''Franchise/StarWars''-themed opening for the Star Wars specials) consisting of the Mad Scientist finding a chicken who tried to cross the road, but got run over in the process. He grabs him, straps him to a table and brings him back to life with robotic enhancements, then straps him to a chair and forces the chicken to watch the show. At the end of season 5, [[spoiler:the Robot Chicken managed to escape and get his revenge on the Mad Scientist. Now in season 6, the Robot Chicken gets his revenge by turning the Mad Scientist into a cyborg, strapping him to a chair, and forcing him to watch the show.]]
* The opening speech of the WesternAnimation/SupermanTheatricalCartoons underwent a small change after Franchise/{{Superman}} learned how to fly. Originally, it went, "Faster than a speeding bullet! More powerful than a locomotive! Able to leap tall buildings in a single bound!" The updated speech used, "Able to soar higher than any plane!" for the third line. Then, when production transferred from [[Creator/MaxAndDaveFleischer Fleischer Studios]] to FamousStudios, the speech completely changed.
* ''WesternAnimation/{{MAD}}'' updated the opening with random characters from their sketches and changed the color of their background for every new season.
