Continuity Lock-Out

Go To

"Ben and I decided that we needed more strips and punchlines that only make sense to hardcore readers. Look forward to jokes so inaccessible even we, the authors, don't get them."
Lewis, Terror Island #200

The writers have let the mythos they've generated get so thick and convoluted that a newcomer has very little chance of understanding the significance of anything. They are 'locked out' of understanding the story by all the continuity.

This is one of the main bones of contention between creators and executives. Executives generally want each episode to potentially bring in a new audience. Creators generally want to entertain the audience they have. In a rare case of this wiki taking the side of the executive meddlers, we have to admit that continuity lock-out is never caused by the execs. It has to be written.

The standard answer to this issue is the Previously On segment: many shows open each episode with a short capsule summary of prior events. Of course, Previously Ons have their own drawbacks, such as inadvertently providing spoilers or flat-out not working (because it is impossible to explain everything adequately in the space of 60 seconds). Another answer is to create a Jumping-On Point, where an episode or block of episodes that (at least for the moment) wraps up several long-running plotlines is followed by a block of episodes with relatively little dependence on prior continuity.

Why bother with the intense continuity at all? Simple: An intricate series-spanning plot often results in a stronger and more interesting overall show. You may not catch as many fans, but the ones you do get are yours for life. This does mean that you have be sure to rope in as many as possible early on before the Lockout effect takes hold to make the effort worthwhile.

Some long-running series and certain mediums (such as novels) are designed to be engaged within a linear multi-volume fashion over a period of time, and the authors can't reasonably be expected to keep everything entirely accessible to a newcomer if they want to engage in any meaningful plot or Character Development; if you start reading a seven-volume series at volume five and find yourself hopelessly lost, then you arguably have only yourself (or in some cases the publisher) to blame.

This is particularly prevalent in comic book series, more so than television or film, because while most TV shows run for a maximum of a few hundred episodes (most of which are easily obtainable one way or another) some comic book series run for much longer. (Like Superman: Consistently in print since the 1930s). This, and the fact that comic books can be incredibly rare (with the auction prices this entails), ensures that most new readers are just going to either give up or ignore most of the last 70 years of continuity. In the past, it wasn't uncommon for long-running series to actually recycle storylines with little variation, in keeping with the Seven-Year Rule.

A Compressed Adaptation might cause this. In Web Comics, this can be the impetus for an Archive Binge or a justification for Archive Panic.

The rise of services like on-demand video have done wonders to push this toward Dead Horse Trope status, especially as more series move toward airing fewer episodes in order to put a higher production budget into each and making it easier to catch up (Game of Thrones is the most potent example of this.) The internet allowing for easy access of fan-made sources of information (see: The Wiki Rule) has also made this less of an issue. Still, relying too much on prior material is seen as poor practice, particularly when it involves Expanded Universe stories in other media.


Examples:

    Anime and Manga 
  • Gundam:
    • This happened with the original UC timeline, which is one of the main reasons Alternate Universe series were made. It was also a major driving force behind the creation of Metal Armor Dragonar; Bandai wanted to bring in fans who might have otherwise been stymied by the existing Gundam mythos and were ready to switch production to Dragonar if it outperformed Gundam ZZ. It didn't, but remains a cult favorite.
    • Somewhat remedied by the easy-to-follow-if-hard-to-grab-all-the-nuances Mobile Suit Gundam Unicorn.
  • Parodied in an episode of Sayonara, Zetsubou-Sensei: Itoshiki was driven to despair by, among other things, the fact that his own show had so many running gags that it was impossible for new viewers to understand. Hence, he changed the screen so that it displayed constantly changing information about all the characters and their personalities, and went on to explain several of the nominal puns and running jokes.

    It was also parodied in that they quickly grew tired of those longtime viewers who knew the show so well they saw all the jokes coming.
  • Fullmetal Alchemist. Same goes for the 2003 anime adaptation, especially if you're watching the OVA and didn't see the last few episodes.
  • This is cited as a major problem with Digimon: The Movie. Unless you're already familiar with the franchise, the overall plot will be all but incomprehensible, and the plotholes induced by the dubs edits, resulting from decisions such as cutting down the Hurricane Touchdown segment to a third of its original running time and shoehorning it in with the other two segments of the film (albiet that was at executive insistence), despite barely relating to their events at all and having a whole new set of characters dropped on the audience, aren't helping.
  • Death Note, mostly due to the Gambit Pileup nature of the series. It's possible to jump in within the first ten episodes or so, but after Light and L actually meet each other, forget that.
  • Given that One Piece has been running since 1997, Eiichiro Oda understandably tries to avoid locking out his readers, which can be difficult given the fact that almost everything and everyone in the series is of some importance even if you don't follow the series from the start. Given that collecting every volume of the story released so far will set you back a few hundred dollars, he understandably puts short flash-backs into the story as well as summaries of the various arcs. To offset this, volume 50 is clearly labelled as a good "starting point", complete with recaps, backgrounds and a new direction for the story.
  • Would you believe a simple fanservice-laden Unwanted Harem series like To Love-Ru has this? If you only watch the anime, you'll never find out what's the deal with Celine, where did she come from, and why she's suddenly living with the main cast. Or, until the second anime season, where did Oshizu get herself a new body. Also, the sequel manga To Love-Ru Darkness makes no effort of helping newcomers on telling who's everyone.
  • Tsubasa -RESERVoir CHRoNiCLE-. It is a Massive Multi Player Crossover that requires you to read ×××HOLiC in order to understand what's going on in the background. Even then, you'd probably still be a little lost unless you also happened to have read Cardcaptor Sakura (which, admittedly, is probably the reason why you're reading Tsubasa in the first place), AND X/1999 AND Tokyo Babylon by extension. Reading Chobits also doesn't hurt.
  • Pokémon Adventures has its instances of this, with current, important plot points coming from previous-generation chapters.
  • Just about all the Pokémon movies are completely separate from the series and themselves, so one needn't see them to understand something in the series. That said, they assume you're already familiar with the series itself, as they make little effort to establish who the main cast are or what they're even doing. The first few movies, particularly Pokémon: The First Movie, are even worse — that one expects you to know what Pokémon are, who Giovanni is, why he's so important, and many other aspects someone unfamiliar with the franchise would be totally lost at.
  • Code Geass: So many things happen in each episode, especially in the super-fast pace of R2, just skipping one episode would result in no understanding of the current plot. And it's difficult to understand the plot even while watching normally.
  • Ghost in the Shell: Stand Alone Complex can fall into this due to the episodic nature of its episodes.
    • The first season isn't so bad. Its episodes are cleanly split between "Stand Alone" and "Complex" episodes. Stand Alone episodes are entirely self-contained storylines that are wrapped up by the end of each episode. They're not filler episodes (as they reveal background info for the characters, among other things) but they're not related to the main plotline that gets told in the Complex episodes.
    • The 2nd season gets a little more complicated. Episodes are divided into "Dividual", "Individual", and "Dual" episodes. Dividual episodes seem to be like Stand Alone episodes, except all of them have some minor detail that becomes more important later on. All three episode types cover three different angles to an overarching storyline that eventually unfolds.
    • Following along with the story can be quite confusing if you don't watch either season from the very start, or even if you end up missing even one episode, as the series doesn't use Previously On, and don't use Recap Episodes in the same obvious way that most series do.
      • And all of this headache isn't even including how the original manga and the Mamoru Oshii films are by themselves separate continuities that have nothing in common with each other. Anyone who's just starting into the series will inevitably ask what the correlation is between the manga, the movies, and the anime series.
      • This also proved to be one of the many problems with the 2017 live-action remake. The story ended up confusing fans with the changes made to the source material and also gave more casual audiences questions about references to the original story they didn't understand.
  • Anybody introduced to the .hack series as an anime can potentially run into a giant wall of Lock-Out. The two main anime series, Sign and Roots, are actually prequels to the main stories of their respective Myth Arc which are told in two sets of PS2 games, and thus (although the former does resolve its main story) don't resolve many of the major story-arc significant plot-points of the respective eras. Made worse with the second anime "Legend of the Twilight Bracelet" being the non-canon version of its respective manga, and Roots having been rendered non-canon, with most of its depicted story (though not its myth-arc) events suffering from Canon Discontinuity to the point it's recommended to just skip those two entries entirely. The effect is even worse if you read the novels or manga, which are generally side stories (or for the novelizations/adaptations of the video games Alternate Continuity), with huge references to the main plotlines that aren't well-explained in that form. The games leave some things unexplained (the system restart during the climax of Quarantine comes off as an enormous Deus ex Machina... unless you watch Liminality, which explains why that happened), but left ambiguous enough that that section of the story such doesn't seem necessary. And that's not even getting into .Hack//Link which has its story tied to revisiting the stories of the past parts of the franchise, only for them to get many if not all of the details wrong. While the franchise DOES explain some events in brief that are expanded more on in other material so as to not leave a newer inductee completely lost (you can pretty much just pick up each of the two PS2 game series stories and still get a complete story out of it), you may not fully appreciate this series unless you're prepared to read/watch/play all of it.
  • Three words: Hajime no Ippo. The series has been running for decades and has already clocked in at over 1,000 chapters with no real end in sight. Sure, you COULD jump in later since it's about boxing and thus all you'd need to know is "this character won/lost some previous matches," but without knowledge of who certain characters are or how/why they box a certain way would make it difficult to follow.
  • Vision of Escaflowne is guilty of this, mostly due to focusing ONLY on its story and characters. It's carefully plotted and compressed, the content in the episodes always leads up to something, and there's absolutely NO filler in it (this would have been rectified had the producers had the necessary budget and amount of episodes they wanted), not that this prevented fans from loving it to death.
  • The third Rebuild of Evangelion movie is next to impossible to follow if you haven't seen the original series. For one thing, the vast majority of the Continuity Nods and Mythology Gags make no sense otherwise, and the revelation that Kaworu is the final Angel comes out of nowhere.
  • JoJo's Bizarre Adventure averts this by splitting itself into parts (eight so far, the latest two happening in an Alternate Continuity), each one with a different setting and main character (though characters from previous parts may make appearances, Jotaro and Joesph being the biggest). Each time it reintroduces the concept of Stands and sometimes offers some cliff notes from previous parts when they become relevant to the story (though some continuity bits just get a vague explanation, like how Joesph got his prosthetic hand in Part 2). Thus, it's pretty easy to just pick a part and start from there (which worked for Viz Media initially licensed Part 3 before licensing the previous two parts). If you ask any established fan of the series, "where should I start?", they will usually say "Start from the beginning, and don't skip any parts" in order to discourage continuity lockout as much as possible.
  • Surprisingly averted by UQ Holder!. Despite being a sequel to Mahou Sensei Negima!, a lot of the plots and characters are new and stand apart from the series. When knowledge of Negima is required, concepts and relationship from the series are well-explained.
  • Dragon Ball:
    • While Dragon Ball isn't strictly required for watching Dragon Ball Z (as any viewer of Toonami can attest), it does explain a great deal of things that are brought up in the early episodes and beyond. Why can't Krillin be brought back with the Dragon Balls? Where'd Goku get that yellow cloud? Why is it important that Bulma broke up with Yamcha? Why is everyone afraid of Piccolo? Who are the Red Ribbon Army? Why is it crazy that Goku has a kid? And so on. Fortunately, the story was well-written enough (and had enough recurring flashbacks) that this Trope was averted for the most part, at the cost of understanding most of the characters on a deeper level.
    • With Dragon Ball Z, Toonami made sure to avert this by constantly rerunning past episodes and storylines in order when they ran out of new episodes to run. At one point they ran the show 15 times a week, with 2 episodes every weekday: one new episode, and one rerun, both from different parts of the story, and then marathoning the 5 new episodes again on Saturday. The show was also made widely available on VHS and DVD in "saga" sets diving the show's almost-300 episodes into 14 chunks, making things a bit easier to follow. It apparently worked, because the show was a huge success in the US, despite very few American fans watching the show from the very beginning.
    • Opposite to the Dragon Ball' anime, Dragon Ball GT is almost incomprehensible without prior knowledge of DBZ'''s storyline, particularly since it didn't refer back to DBZ that often like DBZ did to Dragon Ball.
    • Dragon Ball Super has a minor case of this since the show starts on the assumption that the viewer is aware of the events of the Buu Saga. This has caused much confusion for many newer English fans who grew up watching Dragon Ball Z Kai which only went up to the Cell Games and Buu Kai didn't get an English premiere until Super was airing at the same time on Toonami. Also, since the show runs on nostalgia, all the Continuity Nods and Call Backs can be hard to follow, especially the Future Trunks Saga that mixed important plot points from both the Cell and Buu Sagas. The show also assumes the viewer read or at least have passing knowledge of Jaco the Galactic Patrolman, since it doesn't bother to explain where Jaco came from, how he knows the Briefs, when did Bulma get a sister, or who are the Galactic Patrol. Toei attempted to avert some of this by retelling the movies written by Toriyama, so people didn't have to go out and buy the DVDs to catch up with the latest events. You can even skipped the retellings and jumped to Episode 28, the start of the Champa Saga, since Episode 30 is a Recap Episode of everything that has happened up to the point. And though the Resurrection 'F' Saga draws a lot of parallels and plot points from the Namek/Frieza Saga, it's easy enough to follow since it is a basic revenge story.
  • Being the Grand Finale of the Hope's Peak Saga, Danganronpa 3 is full of this. Anyone who doesn't have acute and aware knowledge of Danganronpa, Super Danganronpa 2, and the Gaiden Game Absolute Despair Girls is bound to get completely slipped up and lost over what the hell is going on. Having read Danganronpa Zero, which was never officially released in English, also helps.
  • Hugtto! Pretty Cure is possibly the only Pretty Cure season to suffer from this trope. Being a 15th Anniversary season, Hugtto makes many call backs to older seasons that can fly over a newcomer's head at first-viewing, and to make it even worse, they had straight up crossovers with the Max Heart, Maho, and Kira Kira teams, as well as Cure Dream and Cure Peach. The show assumes that viewers has seen these seasons already and thus never bothers to introduce these characters for the sake of moving the plot forward, which can make these guest characters come off a bit on the bland side.
  • The Hyperdimension Neptunia anime seems to have been made with the assumption that the viewer has already played the games, and thus does little in terms of world building or establishing characters and their relationships. It's not impossible to follow along without having played the games, but important plot points, such as the alternate dimension Plutia and Peashy are from, as well as Rei's backstory and motivation, recieve less of an explanation than one might expect.
  • KING OF PRISM is a spin-off of Pretty Rhythm Rainbow Live that focuses on the male characters, and watching Rainbow Live is pretty much a given if you want to understand the lore. While the first movie, King of Prism by Pretty Rhythm, explains Over the Rainbow's story, the second movie, King of Prism: Pride the Hero, does not play around and immediately throws in things that reference Hijiri, Jin, and June's backstories without any primer. Even worse, you have to watch Rainbow Live to be able to understand one of the biggest spoilers in the series, as it provides context. For Western viewers, this is a lot worse, since Rainbow Live was not licensed for Western distribution, and the King of Prism movies only screened at the Los Angeles Film Festival; Avex themselves have made the series difficult to obtain legally since their export ban on home releases.
  • The Yo-Kai Watch movies have this issue. They tend to heavily involve King Enma. Enma, however, isn't a character in the main anime, so unless you've seen previous films it can be confusing just who he is and what's going on.

    Audio Play  
  • Several of the Big Finish Doctor Who releases circa the late noughties / early tens, to the point that once they managed to wrap up all the major ongoing story arcs they decided not to start any more and focus on stories that worked as standalones. Perhaps the worst offender is the Forge / Hex story arc: The trilogy of "Protect and Survive", "Black and White" and "Gods and Monsters" requires you to have heard the preceding trilogy of "Project: Destiny", "A Death in the Family" and "Lurkers at Sunlight's Edge", and that also needs the previous two "Project" stories ("Twilight" and "Lazarus") plus "The Angel of Scutari", "Arrangements for War" and "Thicker than Water" at the very least (you would ideally have also heard as many of Hex and Evelyn's previous stories as possible). Plus there's the Companion Chronicle "Project: Nirvana", which should ideally be listened to between episodes 1 and 2 of "Black and White".

    Comic Books  
  • DC Comics:
    • This was the reason given for DC Comics' first Cosmic Retcon, Crisis on Infinite Earths, back in 1985: that things were getting too confusing for the fans (in actuality, it was getting too confusing for the writers but they didn't want to admit it).
    • When that failed to solve anything, DC wrote its second Cosmic Retcon, Zero Hour!. And when that failed to solve anything, DC wrote its third Cosmic Retcon, Infinite Crisis. And that also failed to solve anything.
    • Infinite Crisis was a particularly good example of this trope. To fully understand what was going on, one had to have read at least almost every comic event DC had put out in the past twenty years, Crisis on Infinite Earths, the five mini-series lead-ins to Infinite Crisis, the comics that introduced elements of those mini-series, and Justice League International.
  • Chris Claremont took this to eleven with his out-of-continuity miniseries X-Men: The End, which tries to bring every subplot of 30 years to a satisfactory conclusion.
    • During his run on X-Men, Grant Morrison stated that he wanted to make the book more accessible to new readers by avoiding mentioning past storylines beyond vague summaries. Once he left the book, the subsequent writers went right back to the older, continuity-heavy storytelling style.
    • The first movie did far better business than expected. A number observed that not only were the comics mired in their own complicated storylines and prominently featuring non-movie characters instead, but that Marvel didn't even try to tie-in to the movie - which is understandable, since film adaptations of comic books are generally considered to be aimed at a distinct audience and exist within their own continuity anyway. Consequently, the comics saw no boost in readership as the movie raked in millions, so the trope was cited. Crossover traffic may not have happened regardless and this next part may not be true, but the trope is widely believed to be the reason why Bob Harras was fired from Marvel.
  • Fred Perry's Gold Digger has a degree of Continuity Lockout nearing that of The DCU, despite having only existed since the early '90s and consisting only of one main title, a short-lived spinoff, and a few early crossovers with Ninja High School. Miss a few issues and you're likely to be met with a completely different set of cast members some of whom haven't shown up for a few years, sometimes not even mentioning the main characters.
    • He is trying to combat this with the 101st color comic, set a few years after the 100th and having some new archaeologists under the tutelage of Gina. Who is also a professor.
  • The Gail Simone run on Wonder Woman was pretty continuity-heavy and sales fell sharply during it, with the writer herself later lamenting that her run might have been confusing to new readers. DC hired J. Michael Straczynski to replace Simone and bring in new readers with a highly-publicized storyline that took place in a more accessible Alternate Continuity. Brian Azzarello took Wonder Woman back to a more classic take, but he has said he will be making a deliberate effort to avoid bringing up past storylines and characters so as not to alienate new readers.
  • Ultimate Marvel was created starting with Ultimate Spiderman in 2000 to avert this very trope offering a clean slate for new readers who otherwise couldn't be bothered to dig through decades of continuity in the regular universe to get the gist of certain characters and stories. Nonetheless however, the Ultimate Universe eventually fell victim to this trope despite a few efforts to relaunch it in its later years following the much reviled Ultimatum (which curiously was its own attempt to provide a clean slate for the Ultimate Universe). Namely why certain characters were dead and why the Reed Richards of this universe went crazy and became an outright villain known as "The Maker".
  • Untold Tales of Spider-Man came about in particular, because at the time (1995) the Spider-Man books were in a state of continuity lock with the Spider-Clone Saga and Marvel wanted a book for fans who wanted a Spider-Man book that did not require buying EVERY Spider-Man book being published, in order to understand what was going on.
  • According to Jeph Loeb, this is the major reason why Linda Danvers, the 90's Supergirl, was benched so that DC could bring back the original Silver Age Supergirl. His argument was that Linda's origin was far too confusing and tenuously-tied to the Superman mythos to make sense to casual fans, which is hard to argue. After all, "Kara Zor-El is Superman's teenage cousin who survived the destruction of Krypton while in stasis" is a far more coherent origin story than "Linda Danvers is a teenage Earth-born Angel of fire who merged with a protoplasmic creature from another dimension to become the new Supergirl".
  • Uncanny Avengers has been said to have this. Unless you have read Uncanny X-Force, don't expect to know what's happening beyond the introductory arc. The villains themselves are the result of a story arc from Uncanny X-Force and Wolverine's son is reintroduced with no explanation for who he is or his history for new readers, as are his associates. Unsurprisingly both Uncanny Avengers and Uncanny X-Force have the same writer.
  • The New 52 had this happen to many of the writers, who have talked in interviews about the lack of consistency on the editorial staff while it started up, with no creator able to learn about other books' upcoming plotlines, yet still having to work interactions between them in each month's Crisis Crossover. It happened in record time, too.
  • Archie Comics was forced to do this to Archie Comics' Sonic the Hedgehog thanks to the Screwed by the Lawyers that lead to the Cosmic Retcon. However, Ian Flynn has said that while the first 251 issues have happened (and issues 248-251, part of Sonic the Hedgehog/Mega Man: Worlds Collide, will happen as it's part of the future) they have no bearing on the comic after #252. Just a few years later, the comic went into indefinite hiatus and was ultimately canceled entirely.
  • The Boom Kids comics based on the old Disney Afternoon shows. Due to massive Continuity Porn, they'll only make total sense to people who've seen the shows — which Disney has barely aired at all in the past decade and not at all since 2006. If you're under 20, chances are you'll be confused from Issue One.
  • DC Rebirth: Knowledge of Flashpoint, Watchmen, the Jamie Reyes "Reach invasion" arc of Blue Beetle, and so on are required for anything to make sense. God help you if you are a casual comic reader who's heard of this major DC Comics un-reboot and is trying to use this as an introduction to the DCU.
  • One of the possible reasons Patriot has been Exiled from Continuity while the rest of the Young Avengers have thrived is because Eli's origins are closely tied to The Truth: Red, White & Black and The Crew, two lesser-known miniseries that have been out of print for over a decade, whereas almost all the other Young Avengers have much vaguer ties to the rest of the Marvel Universe.
  • Runaways has long been prevented from experiencing a proper revival due to its format being such that it's very hard to explain the team's history in only a few sentences, especially when its members include the descendant of an ancient clan of dark wizards, the half-human son of Ultron, and a possible demigoddess from 19th-century Switzerland.
  • Vampirella: Happened with the Brandon Jerwa run of Vampirella in Dynamite. Ben introduced many characters from the old Warren and Harris comics which Dynamite fans would not have been familiar with as well as a cosmic conflict between Order and Chaos that involves science fiction elements as well as time travel. This resulted in the Gainax Ending of the first Dynamite series and a complete continuity reboot.

    Comic Strips 
Nearly every comic strip in existence is written under the belief that not everybody either gets the newspaper every day or reads the comic section, so most of them are of a Gag-a-Day format to avoid this. However...
  • Modern newspaper strips with running plots generally get around this by decompressing the plot so much that every minor detail happens over at least 3 days. This also means you have to read several months' worth of strips to get anything meaningful out of it.
    • However you were on your own with regards to older-style serialized stories that offered little by way of recaps or "previously ons". If you didn't follow a story from its beginning, you often had a hard time figuring out the plot. This was intentional as the purpose of the comic strip serial format was to sell newspapers.
  • Both Floyd Gottfredson's Mickey Mouse daily strips and Ward Greene's Scamp daily strips began as essentially one continuous story, but both eventually shifted to gag a day formats.
    • That also makes them particularly tricky to separate into individual stories for reprinting in comic book form (besides the obvious fact that they have to make up a meaningful name for the story arcs), for example, Gottfredson's Mickey Mouse as the Monarch of Medioka (printed in WDC #593-599) starts off with a conversation referring to the immediately preceding adventure, and the plot is set in motion by spending of the money they made off of said adventure. The preceding story, In Search of Jungle Treasure was printed in issues 4 and 5, so unless you have a complete collection, you have to take their word for it.
  • Fleep was an Ontological Mystery, so the entire story was progressed through clues slowly gained over the various strips. It was canceled for being too confusing.
  • Candorville is doing its best to avert this, sometimes filling a panel with As You Know dialogue, but it's been steadily failing ever since it started introducing monsters and prophecies. Now there are 2-3 factions trying to Take Over the World, and a new reader may not initially realize that any of them are present.
  • Bloom County hangs a lampshade on the concept in this strip.
  • Doonesbury is a victim of this. 40 years of strips with close to 100 characters, around 30 or so who appear on a regular basis.

    Film 
  • The Two Jakes was a sequel to Chinatown that almost required viewers to know everything from the first film, such as why Katherine Mulray was so dang important. Despite arguably being just as good as the first time (and Directed by Cast Member), it left theaters quickly. It caught on when it was Vindicated by Cable.
  • Star Wars might be the quintessential example of this. Even on its own terms, the original 1977 film (A New Hope) has a fairly convoluted, confusing plot until Obi-Wan Kenobi shows up about a half-hour or so into the picture to explain everything you need to know, and even then there is much that (necessarily) remains inaccessible to the viewer. The iconic character of Boba Fett, who is "officially" introduced in The Empire Strikes Back (1980) but had actually appeared earlier in (now almost impossible-to-find) The Star Wars Holiday Special, is never even named on screen (except for a brief scene in Return of the Jedi, and that is in the middle of a firefight where it's all but impossible to hear anything); therefore, when we meet that character's father, Jango Fett, in Attack of the Clones (2002), we have no way of knowing, outside of the immediate context, why this character and his son are so important, and must rely on the franchise's large amount of supplementary material. In fact, you don't even learn the name of "The Emperor", the entire series' primary antagonist, until The Phantom Menace (1999), with the result that many first-time viewers had no inkling - until it was revealed at the climax - that "Senator Palpatine" is also Darth Sidious, let alone that he would become the head of the Galactic Empire.
    • As of 2014, resulting from Disney's acquisition of Lucasfilm and the edict therein, the lock-out has been broken due to moving nearly every piece of media ever released for Star Wars into an Alternate Continuity. The Expanded Universe is being rebuilt under Disney's lead with new works and information that will align with their sequel trilogy and associated works.
    • Solo features an example tying with Expanded Universe material that came before it. Audience members who did not watch Star Wars: The Clone Wars (and to a lesser extent Star Wars Rebels) will likely be wondering why Darth Maul is still alive and kicking or if they only knew about his survival via word of mouth, why he has any involvement in the criminal underworld near the very end of the movie.
  • The Harry Potter films have had this problem in an unusual way. Each individual movie became more or less incomprehensible without reading the books (or indeed, seeing the previous films).
    • Moony, Wormtail, Padfoot and Prongs. Prisoner of Azkaban never says who they are. Then, Harry calls Pettigrew "Wormtail" in the Goblet of Fire movie without explanation. And Sirius is called "Padfoot" in Order of the Phoenix.
    • Harry Potter and the Deathly Hallows: Part 1 relies heavily on a shard of a magical two-way mirror as a visual and plot device - despite the fact that said mirror had never appeared in the movies before. Sirius had given a gift to Harry as a gift at the beginning of book 5, and Harry forgets about it because he is worried it is something that could get Sirius into worse trouble. Harry finds it again after Sirius's death and unwraps the mirror - one part of a two-way communication device which Harry could have used to verify Sirius was okay, thus potentially saving Sirius's life. Harry breaks the mirror in frustration and finds the shard as he cleans out his trunk a year and a half later at the beginning of Book 7.
  • The Star Trek movies (to a large extent) avoided this, save for Star Trek: First Contact (which assumed the viewer had some knowledge of the "Best Of Both Worlds" two-parter and Star Trek: Deep Space Nine for Worf's location during the cube battle). However, the latter really isn't that important and only requires a single line by Picard to establish Worf wasn't with the crew anymore, and Lily is an Audience Surrogate who becomes a sounding board for Picard's frustration. Several other examples are peppered throughout the films:
    • Data's emotion chip is an interesting example. Star Trek: Generations and First Contact both have Data mulling over whether to use the chip or not. New viewers to these films won't understand much of what Data's talking about unless they've seen the earlier seasons of TNG (specifically the fourth- and fifth-season episodes regarding Data, Lore and Dr. Soong). Not that viewers of the show are much better off, since the end of "Descent Pt. II" had the chip irreparably damaged before it shows up again in Generations,apparently fully-functional and represented by a prop that looks nothing like that used in the series.
    • Star Trek: Insurrection averted this trope. According to Michael Piller's unreleased book, Fade In: The Making of Star Trek Insurrection, at least one plan was to have Picard and his crew look for a Federation traitor (a la Heart of Darkness) against the backdrop of the Dominion War (during the point when the Federation was losing ground against the Jem'Hadar). This plan was scrapped due to concerns that theatregoers wouldn't understand the references (which didn't stop them from referencing the aforementioned Deep Space Nine and "Best of Both Worlds").
    • Star Trek (2009) also largely averted this - seeing as it specifically sets itself as an origin story in a clear alternate continuity (if Hand Waved connected to the original through use of the Timey-Wimey Ball). However, the tie-in comic, Countdown, is the canonical last appearance for many of the TNG characters, as well as the only way you'll get to find out the backstory for Nero and his ship (which, in turn, references past elements of the franchise, all the way back to V'Ger).
    • Star Trek II: The Wrath of Khan can be a little confusing for viewers not familiar with the episode "Space Seed," which introduced Khan and established his rivalry with Kirk. The movie does give a basic overview of their history, but it's in tiny chunks scattered throughout several different scenes, so a first-time viewer would be excused for not totally grasping why they hate each other.
  • Movies based on comics start with the premise that the movie requires no knowledge of the comic since it's telling its own version of the story. That premise is quickly violated.
    • Example: X-Men Origins: Wolverine could have used footnotes to explain the significance of its story elements. Since the Weapon X scene was so brief, it could have said "To learn more, please read Weapon X by Barry Windsor-Smith." One benefit is that you get to spend more time with your non-comic-savvy friends explaining the plot. Whether they'll care or not is another story...
    • The Marvel Cinematic Universe did a fairly good job averting this at first, throwing in Easter eggs for comic readers without making it confusing for others. However as the franchise expanded and plot lines intersected, it's become its own tangle; Infinity War effectively requires that audiences have seen not just the previous Avengers movies, but also Captain America: Civil War, Thor Ragnarok, Guardians of the Galaxy, and arguably Black Panther.
  • The DC Extended Universe seems to be doing this. A major criticism of Batman v Superman: Dawn of Justice is that certain parts of the movie make no sense to people who haven't read the comics, and are likely to be expanded upon in future installments. Most notably, the "Nightmare Sequence" (which wasn't even in the original script and was improvised by director Zack Snyder) is virtually incomprehensible to anyone who isn't familiar with Darkseid, Darkseid's symbol, Parademons, and the New Gods.
  • This is definitely one of the reasons why the second and third chapters of The Matrix Trilogy are so polarizing. It is better to watch all three movies on consecutive nights rather than four years between the first and second movie.
  • Peter Greenaway's Luperverse movies, The Falls, The Tulse Luper Suitcases, Drowning by Numbers and several short films, are a deliberate appeal to this trope. His main character, Tulse Luper, generates so much writing and ancillary material about himself (both in canon, and, via Greenaway, In Real Life as well) that no one can write his definitive biography. Lampshaded in his very first appearance in Vertical Features Remake, where a team of academics utterly fails to recreate a lost film Luper made while relying on vague notes and the memories of his collaborators.
  • Ralph Bakshi's take on The Lord of the Rings seems to assume you are already familiar with at least the bare bones of the story, since they refuse to explain anything beyond "And so it was that..."
  • In a bizarre instance where the first sequel has Continuity Lockout, Final Fantasy VII: Advent Children is nearly incomprehensible unless you've played the game.
  • The M. Night Shyamalan film The Last Airbender, based off the TV series Avatar: The Last Airbender, takes most of the key plot points of the series and represents them in a movie format. This trope happens because of the compressed timeframe to tell the story. You never really understand how Aang is trapped in an iceberg, why Katara decides to leave with Aang dragging Sokka along and the nature of why Aang "glows up" in stressful moments is never explained (admittedly, the Avatar State isn't fully explained until the second season, but it happened enough times in the first season to understand its purpose). If you're familiar with the series most everything fits into place (though very poorly, due to plot holes caused by the changes in the story).
  • The M. Night Shyamalan film Split, released in 2016, has a Twist Ending that's only a twist to the viewer if they've seen Unbreakable, a movie of his that came out in 2000. Otherwise, the viewer might not know the significance of David Dunn (Bruce Willis) showing up.
  • One of the many reasons why The Godfather Part III is polarizing was because of its complete inaccessibility to audience members who had not seen the previous two movies. Wrote Roger Ebert at the time "It is, I suspect, not even possible to understand this film without knowing the first two." However, Ebert still enjoyed the movie and rated it higher than he did Part II.
    • In what is something of an irony, the producers and executives were a little wary of applying ''Part II" to the second movie partly because they were concerned that people might get the impression they needed to see the first movie in order to understand the second one, which might turn off new audiences. The second movie, however, is generally more accessible, and in general started the trend of Numbered Sequels.
  • David Lynch's adaptation of Dune is nigh-impossible to comprehend without reading the book, particularly its last forty minutes or so which are an incredibly rushed depiction of two-thirds of the book's length. Especially bad is the scene where Paul decides he needs to ride a sandworm to properly lead his new army, despite the fact that the Fremen ride the worms never having been referenced. In 1984 audiences were even handed playbills before entering the film to explain the plot they were missing. The extended cut DVD release restored several missing scenes and pieces of exposition and is considerably easier to follow.
  • Mortal Kombat: Annihilation has a huge number of plotholes unless the viewer knows the mythology of the video games. Sub-Zero and Scorpion both die in the first movie and they're back alive here. What the film doesn't explain is that Sub-Zero is merely a title, and the Sub-Zero from the first film was the brother of the one in the second film. Scorpion is, in fact, undead. Fans of the games on the other hand would most likely know all of this.
    • The film does have a (throw away) line about being the brother of Sub-Zero, and being that the first movie showed Scorpion removing his mask to show a fire-breathing skull him coming back to life isn't sharp leap. Watching the second movie and not the first, however, would still count as a lockout, but that can be said for any time someone watches a sequel without seeing the previous works.
  • Die Hard with a Vengeance (1995) has a memorable allusion to "that thing in the building in L.A.", which knowledgeable viewers will recognize as a Continuity Nod to the attempt by Hans Gruber and his gang of thieves to rob the Nakatomi Plaza tower in the original 1988 Die Hard movie. Even though there's a brief flashback to the climax of the 1988 film within the 1995 sequel, it can be difficult for first-time viewers to understand why Simon Gruber (Hans's brother) is so consumed with the desire to exact revenge on John McClane, the series' hero. The 1995 film even has an offscreen conversation between John and his ex-wife Holly, who was a major character in the first Die Hard (and is mentioned again in the fourth movie, Live Free or Die Hard, in 2008) and is the subject of the '95 film's closing punchline, which seems to come out of nowhere and make for a somewhat confused ending if you are new to the franchise.
    • Although McClane does briefly explain to Zeus that he dropped Simon's brother off a building not long after The Reveal.
  • Rambo (2008), the fourth film of Sylvester Stallone's First Blood franchise dating back to 1982, opens with John Rambo working in the Southeast Asian country of Thailand as a trapper of poisonous snakes. It's soon mentioned in the dialogue of the movie that Rambo is an ex-Green Beret who fought in the Vietnam War, but that dialogue skips over the events of the three previous movies (with which longtime viewers should be familiar) during which Rambo returned to the United States and later went to Afghanistan to fight the Soviets, with no reference point except for a brief montage during which Rambo flashes back to the events of the original First Blood (1982) and imagines himself screaming "Nothing is over!" The naive viewer will be forgiven for assuming at first that Rambo has remained in Southeast Asia for the past 40 years. This is lampshaded in a conversation he has with one of a group of missionaries who have come to enlist him in a rescue mission.
    Sarah: Where are you from?
    John: Bowie, Arizona.
    Sarah: Why'd you leave?
    John: I got drafted in 'Nam.
    Sarah: And you just stayed?
    John: It's complicated.
  • Very few would argue that X-Men: Days of Future Past strikes with full impact if one has skipped some or all of the other X-Men films. At the very least X-Men: The Last Stand which explains Logan spazzing out over the random redhead (a very much alive Jean Grey) at the end and X-Men: First Class (which explains... pretty much everything else).
  • The Marvel Cinematic Universe:
    • This article warns that this trope might happen to the franchise if it expands itself too much too quickly.
    • Hawkeye's appearance in Thor. Non-comic fans are left clueless why the movie spent five minutes bringing in a big name actor to play a random wisecracking guy with a bow and arrow, who never appears in the film again, though this made sense when The Avengers came out.
    • It's possible to enjoy The Avengers if you haven't seen all the individual movies beforehand, as long as you've got a rough idea of who everyone is (e.g. Steve is a Fish out of Temporal Water, Thor is a Norse god with an almighty hammer, etc.), but if you want the backstory of each character you'll have to watch five other movies.
    • During production on Avengers: Age of Ultron, Joss Whedon said that he wanted to make sure it was accessible enough that it could be understood even if you'd only ever seen the previous Avengers movie. This proved to not be the case, as there are cameos (some of which are very relevant to the plot) from characters that had previously only ever appeared in non-Avengers films, and a key plot point involving the Infinity Stones really only makes sense if you've seen Thor: The Dark World and Guardians of the Galaxy.
    • Prior to the release of Captain America: Civil War, The Russo Brothers stated that they'd made the film on the assumption that most of the audience had already seen the previous Marvel movies. It shows. The movie is virtually incomprehensible unless you've not only seen the previous two Captain America movies (though that should be obvious since they're in the same series), but the previously mentioned Age of Ultron as well. Certain key scenes also rely on the audience having knowledge of Iron Man 3, Ant-Man and The Avengers. In an example of Tropes Are Not Bad, many critics and fans praised the way the film applied this trope to Spider-Man. The movie doesn't explain his origin or reveal too much about his backstory, as there was an unspoken assumption that most of the audience already knew the character from any of his previous five movies or numerous TV shows.
    • Quite a number of things in Thor: Ragnarok will make more sense if you've watched the previous Thor movies and Avengers: Age of Ultron beforehand. Otherwise, you won't really understand why Thor and Loki's relationship unfolds as it does in the movie and Bruce Banner's own subplot in the movie.
    • Avengers: Infinity War broadly assumes that the viewer has seen all of the previous MCU films, as it's chockful of nods and references to prior incidents in the timeline. However, it most specifically requires that the viewer has seen the previous Avengers films (to know that Thanos is involved as the series' Big Bad), the first Guardians of the Galaxy (as the main team and the Collector are present), Captain America: Civil War (as Infinity War begins with several team members on the lam after being broken out of The Raft at the of the previous film, and heavily involves Spiderman and Black Panther who were introduced in that movie), Thor: Ragnarok (which explains why Thor, Loki and Hulk are on the Asgardian ship) and Black Panther (which sets up Wakanda, the setting for the film's climax).
    • Happens in the trailer for Captain Marvel (2019), which features a scene of Carol punching an old woman on a bus with absolutely zero context. Comic book fans and people who've been following the movie automatically assumed the woman was a Skrull (an evil race of aliens capable of shape-shifting) despite the fact that the trailer doesn't even mention them. It took until the second trailer for the Skrulls to show up and the woman to be shown fighting back against Carol.
    • This is the general explanation for why none of the characters from the present day TV shows (Agents of S.H.I.E.L.D., Daredevil (2015), Jessica Jones (2015), Luke Cage (2016) and Iron Fist (2017)) appear in the movies, even the ones involving Crisis Crossovers. The movies generally have a wider audience than the TV shows (and are released in certain countries where the shows don't even air), and the creators don't want to have to spend time explaining who the hell these people are for the benefit of audience members who might not be familiar with them.
  • There is so much omitted from the movie adaptation of Watchmen that even the character motivations and progression of plot from one to the next are removed, not to mention the total removal of Tales of the Black Freighter comic book within a comic book that explains Ozymandias's state of mind. In order to enjoy the movie to its fullest extent, the viewer must already be aware of the events of the comic book. Although the 3 1/2 hour 'Ultimate Cut' fixes most of this.
  • The Back to the Future sequels get into this.
    • If you haven't seen the first movie, Back to the Future Part II is easy enough to get into in the first couple of acts (barring the occasional Call-Back to events in the first movie), but the 1955 events in the third act are entirely dependent on the viewer's knowledge of events in the first movie.
    • Back to the Future Part III gets snippets of exposition in the first few minutes in the forms of Marty screaming and Doc's letter, but it's a LOT tougher to get into if you aren't familiar with the first two movies. Especially the first movie's climax, which is reworked into Part III's intro.

    Literature 
  • The Elder Scrolls novels are based on the video game series, and if you don't know the continuity and lore then most of the events of the novel will sound like an Ass Pull when it actually does Make Sense In Context.
  • In another example of a creator locking himself out of his own continuity, John Varley, in an introduction to one of his Eight Worlds novels, admits that he's long since lost track of all the background details of the series, and has given up trying to make the later novels fully consistent with the early ones.
    • Terry Pratchett said much the same in the introduction to the first edition of The Discworld Companion. Although he does still make the effort; if necessary consulting with Big Name Fans who actually know more about the Discworld than he does, such as the Companion co-author Stephen Briggs.
      • Pratchett wrote his way out of having to be consistent; all errors are blamed on the fact that even the History Monks can't quite always get time back exactly the way it should be after the magical disruptions that occur.
  • As the The Wheel of Time series progresses, and both the cast and pagecount swell, individual characters get less and less face time. It's sometimes several hundred pages between a character's appearances, even for main characters. Two of the main characters, Mat and Perrin, have even been left out of a book at one point or another. Worse, the characters have often been active in that time, leaving the reader to infer what happened since they were last seen. Not that we're bitter. In fact, it is quite clear that till the 4th book or so, each book provided info from previous books, including character development history and some important pieces of lore. However, by the 5th book, no more "backward compatibility" is provided and the writer assumes that readers have read the previous books. To the point of removing anyone 3 books or older from the glossary. Readers may have trouble remembering which of the 20 A-named female channelers was Aes Sedai, Rebel Sedai, Aeil, Seachan, or Dark-aligned. They tend to blur together after 10,000 pages or so.
  • Foundation: Isaac Asimov put his series on a decades-long hiatus in the 1950s partly because he was exhausted from having to reread the material to keep it consistent and to write an engaging synopsis of previous events to prevent new readers from feeling locked out of the current story. A fan later handed him a long list of inconsistencies within the Foundation stories.
  • The Dresden Files became this from the very first sentence of Changes. Even beforehand, there were plots that were foreshadowed over the course of several books, characters who were introduced and left only to come back five books later, an overarching war in the background, significant changes that impact how Harry treats certain characters, and many short stories that get a passing reference in the novels.
  • Harry Potter: If you start reading anywhere from books 1-3, then you'll be fine, since character backstories, running plot devices, past major events and such are usually given a short explanation, treated as a Noodle Incident or just aren't relevant to the actual conflict (for now). However, after the Wham Episode from Goblet Of Fire, books 5 onwards have problems keeping the continuity intact, since it's very difficult NOT to talk about the events of the fourth/fifth book. It got to the point where the last book in the series became impossible to read because of the spoilerrific nature of the story and continuity becoming prevalent.
    • JK Rowling herself stated she was invoking the trope from about book 4 onwards, remarking that anyone starting a 7-book series halfway through shouldn't really be surprised when they find themselves confused by the continuity.
  • Trying to get into George R.R. Martin's A Song of Ice and Fire involves going through five (eventually, seven) Door Stopper novels, each with so much continuity that it's no wonder the man is taking ages to continue the series. If he creates a plot hole, someone's going to try to call him on it before the book gets to the editor.
    • Interestingly, the author later wrote two prequel novellas (with a third on its way), starting with The Hedge Knight which essentially reproduced the Ice and Fire themes about power and politics down to a much smaller and far easier-to-digest form, and radically less intimidating to newcomers, particularly the graphic novel adaptations.
  • Stephen King hired author Robin Furth to be his archivist and continuity editor to assist him in writing the final books of The Dark Tower. She compiled an encyclopedia that King referred to during writing that was published itself as Stephen King's The Dark Tower: The Complete Concordance. He says in the foreword to that book that there was no way he could have completed the series without such a document. And sadly, it shows. Many of the books most important plot points are mentioned only in passing, which can result in a whole mess of confusion even for those who have read all the books in order.
  • Perry Rhodan has a real problem with this. With a backstory of over 2500 issues in the main series alone that might become relevant for the current plot at any time and story arcs that last for 50 to 100 issues it can be quite hard for new readers to break into the series. Nowadays they take some pains to make the round numbers a good place to start, without too much pre-knowledge. Also, in each issue there is a small glossar explaining plot-relevant background that a new reader might not know (or an old reader might not remember).
  • Warrior Cats: It is possible, if not a bit difficult, to start reading the second series without reading the first series. However, by the third series, things apparently get nigh incomprehensible for people who haven't read all of the previous books. The fifth series is a prequel, which could be read without reading the other books, but the prologue and first chapter or so of The Sun Trail would be kind of baffling (and very spoilery) for a newcomer.
  • Katherine Kerr's 15-book Deverry series is divided into four parts; starting at the beginning of any one of the three latter will cause you to only miss half of the significance of what's happening... The Dragon Mage (3rd series) is probably the worst offender, since it tells about the end of the civil war, which has been earlier covered in three other books.
  • To keep up with all the various plots and Loads and Loads of Characters in Honor Harrington by David Weber, you not only need to read the mainline titles, but the sub-series and short story collections, which are themselves not in chronological order. Go here for a reading order.note  The books are mostly free, so it won't set you back much. That said, the Star Kingdom Spin-Off series generally averts this, thanks to a time shift of several hundred years into the past, before Manticore became enthralled in transgalactic political espionage and warfare. It's also written for a Young Adult audience, so its action is pretty much confined to Sphinx.
  • Eric Flint's 1632-verse is a "shared universe" open to anyone who wants in. In other words, any fan of the series can write their own contributions to it and have them entered into canon if they pass muster with a review board for the series. Flint and his co-writers then tend to take characters introduced in these stories and work them into the main series. Thankfully, the short stories that have the most impact on the main story have been collected into their own "Ring of Fire" anthologies.
  • Various Star Wars Expanded Universe works assume the reader has at least basic Broad Strokes knowledge of important EU events and don't even try to make sense otherwise. Amazingly, other works still manage to remain accessible, though the knowledge of the movies is still required.
  • The Babylon 5 novels are plagued by this, because while some of them are noted as taking place after the events of specific episodes, they aren't necessarily sequential, and are all written by different authors.
  • The Thursday Next books by Jasper Fforde do a brilliant job of constantly inventing new concepts, settings and characters whilst referencing and being consistent with previous books. But if you read them out of order they'll make almost no sense at all.
  • L. Frank Baum's Land of Oz books could get like this. Not only did he assume a lot of memory of Ozian geography and politics, any time he liked a character, he'd just keep them hanging around the Emerald City for later use. In the last few books in the series, there were entire chapters devoted to choosing which of the series' Loads and Loads of Characters would be going on the novel's adventure. There was Button-Bright, Ojo, Cap'n Bill, Uncle Henry, Tik-Tok, The Patchwork Girl, the Frogman, The Woggle-Bug, the Hungry Tiger... The Lion, Scarecrow, and Tin Man would almost always be there, and the Wizard usually put in an appearance, but anyone who knew the movie and wanted to give the books a shot could easily become very lost.
    • Baum himself could get lost in the character mess. In one novel, he has The Shaggy Man and Polychrome meeting for the first time, apparently having forgotten that he introduced them in the same book.
  • Both the series of post-TV-show prose Doctor Who spin-offs from the "wilderness years", the Doctor Who New Adventures and the Eighth Doctor Adventures, suffered badly from this, with many novels from both series being completely incomprehensible if you hadn't read earlier books in the Story Arc. And preferably watched some of the less-regarded episodes of the series, possibly while taking notes of every throwaway line that mentions an alien race.
  • The Star Trek Expanded Universe novels can be similar, especially the "Relaunches", which are frequently telling one long story, and don't believe Status Quo Is God, so even a committed Star Trek: Deep Space Nine fan who's seen all the episodes might be confused by jumping in to the middle of the Star Trek: Deep Space Nine Relaunch series.
  • Goosebumps: The HorrorLand series debuted nearly 10 years after the 2000 series, and featured a Crisis Crossover with many heroes and villains from the original series, published long before their target audiences were even around. In order to alleviate the lock out, every book came with a reprinted edition of the classic book the new one continued, or at least one that was thematically similar.

    Music 
  • Any band that's been around more than five years or so. You can get into and like the music with any band, but if you're seeking to get into the fandom side or be seen as anything but a noob, much less knowledgeable and intelligent, if a band's been around longer than five years, you'll need to check out all of their work, engage with active fans that were around from the beginning (or at least, themselves read up on the fandom lore) and be a lurker until you know what you're talking about to avoid Flame War.
  • Influences and inspirations for songs, lyrics, stage presence, or more, which can change your opinion or liking of a song or even a band.
  • Go on, try to understand what's going on in a Coheed and Cambria song if you've never read the comic books.

    Other 
  • BIONICLE eventually got this way, especially after the introduction of the on-line serials. The main story arcs tended to avoid this, but when former main characters that had been cast aside for years got back on stage, even that went messy. The whole storyline balanced on a thin line between trying to please the older fans and bring in fresh blood. This was probably one of the main reasons LEGO decided to put the line on hiatus and bring in Hero Factory, which was much lighter on the story and had little to no continuity; and when it was brought back it was given a Continuity Reboot to help clear things up.
    • An additional problem was that much of Bionicle's story was told in online media, from games to animation to web serials (written or read as audio files), and so much of the media just did not exist anymore or was no longer up for new readers to catch up on.
  • Kagerou Project: The franchise's beginnings as a series of character-driven (and seemingly unrelated) songs - with only minimal information released by the project's creator - has led to a lot of new fans feeling alienated due to the complexity of the whole plot (made worse by the fact that the songs don't have an official order), and the Loads and Loads of Characters contained therein. Even the series' other adaptations provide issues, as the manga is still incomplete and the anime (while complete and comprehensive) leaves significant gaps and relies on viewers knowing at least a little about the project and its characters before viewing. The late-game revelation that all 3 branches of media are actually time loops, and that the light novels utilize this plot point from 2014 on, end up retroactively making the rest of the franchise required reading to understand how the books end.
  • This can be a problem with online roleplays that have gone on for years. When a new member wants to join up they have to verse themselves in everything that's happened before.
    • Glowfic likes to make its characters explain their own backstory and universe to other characters who they meet for the first time, as well as playing with this trope in-universe because new characters constantly join an organisation/group/collective and have to be caught up, and (sometimes) they are caught up onscreen, via some old character explaining it to them in conversation.
  • Depending on the extent of Fanon, this can happen - a lot of fandom members tend to assume everybody is on board with their fandom lore, the running gags, the personalities invented (and accepted) by them or have read all the popular fanfiction recommendations. This can lead to some new fans wondering where on earth this is coming from.
  • Many films based on a TV series fall into this trap, as they continue from events in the TV series and assume viewers are already familiar with them. How severe this trope can be depends on its connection to those events, as well as the setup of their respective series: a film with a self-contained story can easily be enjoyed by unfamiliar viewers as a standalone work, whereas one with a complex mythos and already-established characters will leave them completely lost.
  • Pinball is an entire medium that has fallen victim to this. Every pinball machine released since The Addams Family has assumed the player knows how to start a game note , pushing the Start button multiple times will begin multiplayer note , what locking balls do note , how the ball count works when you win extra balls note , what the loud knock from inside the cabinet means note , what "VUK" means note , how many balls are in a standard game note , what a "ramp" is and what makes it different from a "lane" or an "orbit" note , what a "bonus multiplier" is note , the existence of match games note , that most modern machines will give you a free ball if you drain too quickly note , what it means when the "Shoot Again" light is flashing and what it means when it's continuously lit note , and that "Score #1" is actually the second-best score after Grand Champion note . People who have been playing pinball for years will know these things, but a beginner likely won't, and will instead do things like mash the Start button to begin a game, as that's how it's done in video games, and unintentionally and unknowingly start maximum-player games.

    Professional Wrestling 
  • Usually avoided in pro wrestling, since most of wrestlers and such (at least if they fall between the two extremes of "irrelevant" and "universally popular") will switch from Heel to Face and back again (or vice versa) quite a few times over the course of their part in an angle, with their contemporaries all but forgetting about the bad deeds they committed as Heels or the good deeds they committed as Faces (unless a wrestler is explicitly confronted with his/her past). However, since World Wrestling Entertainment has a video archive going back to the 1960s and everything (or almost everything) that occurred since 1983 is regarded as canon, it often becomes helpful to play vintage video clips in the montages in order to bring everyone up to speed. (Anything that happened in the 1950s or earlier is, for the most part, written off as being the province of the wrestling "territories", ultimately embodied by the National Wrestling Alliance, which has an ongoing history dating back to the late 1940s — and yes, all of those 60-plus years are NWA canon — but from which WWE's original incarnation, Capitol Wrestling Corporation, broke away as early as 1953.)
    • Incredibly, there was at least one WWE personality whose exploits stretch back all the way to the outbreak of World War II, well before the beginning of WWE or NWA: Mae Young (1923-2014), the former United States Women's Champion (a now-defunct title) who appeared on Monday Night Raw as late as March 2013. With an in-ring career spanning literally six decades, Young was generally referred to in Broad Strokes whenever WWE programming discussed her incredible history, usually being hailed as the first nationally prominent female wrestler (not true, although she was alive when first nationally prominent generation was active) and a morale-booster for Americans on the home front during the war in the 1940s (true this time). Attempts have been made to construct a title archive for Young, but so many of her victories happened so long ago and were so spottily recorded that this task has proved frustrating; indeed, it's doubtful if Young herself could remember everything.
    • WWE fired their continuity editor for pointing out the millions of continuity errors. His job was specifically to point out and edit "storylines" to make sure the continuity worked.
    • This has increasingly become an issue in the 2010s, when WWE started signing more wrestlers who first achieved popularity in the independent/international scene. The rivalry between Sami Zayn and Kevin Owens, for example, takes on greater depth when one is also familiar with their previous backgrounds in Ring of Honor and Pro Wrestling Guerilla. And while WWE has done a good job so far establishing the relationship between AJ Styles, Karl Anderson and Luke Gallows, to casual viewers the connection between the three men and Finn Bálor is not readily apparent unless they also looked into the history of the Bullet Club, a heel stable that was created in a completely different promotion on the other side of the Pacific.
  • WWE onscreen commentators both past and present (Matt Striker, to give one noteworthy example) can boast an encyclopedic knowledge of 20th-century wrestling lore, being able to cite references to things that happened long before they were born - and since there isn't time in the middle of a match to bring everyone up to date on what all these references mean, anyone who happens to be casually tuning in to WWE programming is certain to be all but lost, even when it comes to references to events that happened as recently as a few months ago.
  • This was a problem for IWA Puerto Rico's English feed on Fox Sports Net. While cutting out all the promos and video packages and going straight to the matches was refreshing in a way, it was hard for someone casually tuning in to know exactly who everyone was or appreciate their motivations, which was a problem because IWA's big angles at the time revolved around abuse of power, attempted corporate takeovers and their rivalry with WWC, which anyone not up to speed with IWA would know even less about. Competing directly for viewership with TNA Impact, who happened to be signing names already known to the English speaking audience such as Samoa Joe while similar such names like Bison were leaving IWA gave people even less incentive to sit around and figure out what IWA was all about.

    Tabletop Games 
  • This is a general property of Table Top Role Playing Games. Most have highly detailed universes which are contained in Door Stopper books. A good Game Master and group of players will help a new player considerably. Put succinctly, a new player has to learn the mechanics of most games (crunch) as well as the setting (fluff). Despite the name, learning the "fluff" is not always easier - some games have really simple rules and terribly complex ideas behind them. Smart companies design their products around this problem.
  • Additionally, a new player joining a game that has been in progress for months or years can find themselves not only lost in terms of the core game, but in the no doubt hundreds of clashes, allies, enemies and in jokes a group will have created over the years.
    • Dungeons & Dragons and by extension Pathfinder get a bit of a break, as D&D has fertilized so many video games and other fantasy works that some of the material comes off as a cliche within the genre. Despite this, there are literally hundreds of books for the various D&D settings, optional guides, and so forth, spread through so many editions, that without a patient group it can be very overwhelming for a new player.
      • Forgotten Realms alone published dozens of books and boxed sets with every edition.
      • Paizo's Pathfinder Adventure Paths try to get around this by offering free books which brief the players on the adventure to come and what to expect. They're "only" roughly 15-30 full-size pages, and they still require a decent knowledge of the rather complex Pathfinder setting.
      • D&D and Pathfinder have the Continuity Lock-Out problem in their crunch as well. As they constantly release new books with new mechanics, a new player can have five to ten rulebooks of material to sort through. For example, Pathfinder initially had one Core Rulebook, but by mid-2013 now has expanded to include dozens of minor splat books and at least seven that could be considered "options for players." The Core book is about five hundred pages, and each other major book is about two-hundred and fifty.
    • The World of Darkness, Old and New, were prone to this. The typical rulebook was 250 pages of fluff, 50 of mechanics, so a new player would have an immense buy-in in terms of learning the game's feel. Additionally, there were multi-year long metaplots, constant expansions, and a splat book for everything. And the lines all overlapped at least a bit. Fortunately, playing someone brand new to the supernatural world was pretty much the norm, so the characters would be unlikely to know much about the setting.
      • The New World of Darkness shies heavily away from the dense metaplot of the Old World of Darkness, where sourcebooks were like comic book issues: collect them all to have a hope in hell of understanding anything that was going on. While the New World of Darkness does have some metaplot elements, they are dramatically toned down from previous iteration.
    • Shadow Run requires a pretty good grounding in Urban Fantasy and Cyber Punk, plus is full of its own quirkiness. It's not the easiest setting to initially buy into.
    • Call of Cthulhu is a bit difficult to follow if one isn't overly familiar with the Cthulhu Mythos.
      • This is a problem of many games which license another setting, such as Star Wars, A Song of Ice and Fire, The Dresden Files, and The Wheel of Time. Presumably, someone wanting to play these games wants to enjoy settings from other media they like. If they invite other friends who aren't familiar with the setting, the new player has to adapt to all the new rules, mindset, and the setting.
      • Star Wars games often use the Expanded Universe. Given how much of it there is, that can really be overwhelming if all you know are the movies.
    • Warhammer and Warhammer 40,000 are fairly approachable as straight war games without any over-arching fluff, but their various role playing incarnations like Dark Heresy require a massive amount of detail about their settings. The war games do a fairly good job of giving a feel for their worlds, however, with rule-books that are about a hundred pages of rules and three hundred pages of fluff and model galleries.
    • Paranoia subverts this. You're neither expected to know the rules nor the setting going in. If you are caught knowing the rules or setting, it's treason. Friend Computer assures you that knowing the rules or setting are not vital to your success in this mission. Report immediately to Brain-Scrub Room Zeta 462 to have this treasonous information purged from your brain or be executed for treason. Have a pleasant daycycle.
  • All the above problems apply doubly-so for the Game Master, who has to know (or fake) the setting to the satisfaction of the players.
  • Many games release a "beginner's version" to try to compensate for this problem, allowing new players to sample the game at a minimal layout before deciding whether they want put down their hard-earned money and then spend time working through the game at all. Sample adventures which hold the players' and GM's hands a great deal are also used to this effect.
    • Making many new characters naive about the setting is another effective tool to combat this problem, since the player and their character learn together. This is very effective in Unknown Armies, World of Darkness, Call of Cthulhu, and other settings where there really isn't a good reason for the character to know much about the setting. When The Masquerade means new characters are naive, the player can be almost as surprised as their character when they discover something new.

    Video Games 
  • StarCraft:
    • StarCraft II is a slight example of this. There are summaries on the website and the installiation process shows off a recap of what went down in the original games, but otherwise you have to read the novels to know anything about Valerian, Tychus, Matt Horner.
    • Plot advances going unexplained in-game during the 4-year Time Skip between Brood War and Wings of Liberty caused a disconnect for people as well. If you were hoping for a continuation of where Brood War left loose ends off, prepare to be extremely disappointed.
    • You'd have to dig into the franchise's Expanded Universe to understand why Raynor is all of a sudden longing to be with Kerrigan again at the start of Wings of Liberty despite his last appearance in Brood War having his classic character defining moment of vowing to kill Kerrigan someday. We're suppose to believe that he got over his ploy for revenge during the 4-year intermission, but how he got over it went completely unexplained in the game; leaving many players confused as to why Raynor's suddenly in a different emotional state.
    • You'd have to read the Expanded Universe to understand how the Dominion are all-of-a-sudden the top dogs again despite being on the recieving end of many Curb Stomp Battles in Brood War. The player's Willing Suspensionof Disbelief really comes to question here as to how the Dominion achieved such a miraculous recovery; including how Korhal instantly turns into a planetwide megapolis come Wings Of Liberty despite being a desert wasteland 4 years prior in Brood War.
  • Metal Gear slowly rose from humble origins, into the self-sequels Metal Gear Solid and Metal Gear Solid 2, had a brief blip for the stand-alone Metal Gear Solid 3, and then gunned the canon whole-heartedly into the massive continuity snarl-ups of Portable Ops and Metal Gear Solid 4, both of which only a very serious and dedicated fan would be able to understand.
    • As a sort of alternative, the Ac!d games happened in an alternate universe, but they still expected a familiarity with the main phase series with its spoilerrific character cards. In the first game's story, a lot of hints about Snake's identity and motivations require some knowledge of his main phase canon backstory, such as his sterility.
    • Metal Gear Solid 3: Snake Eater is an interesting exception in that while the story can be completely enjoyed and understood on its own it's packed with Continuity Nods and back story for characters in the other games.
    • Metal Gear Solid: Ground Zeroes is not only based on the PSP game (with a PS3/X360 HD rerelease) Metal Gear Solid: Peace Walker, but on a Playable Epilogue ending that many people missed. Few people seem to care.
  • Burial at Sea, Episode 1 will, right up to the ending, actually make more sense to someone who's only played BioShock than it will to someone who's only played BioShock Infinite. Booker and Elizabeth's connection has no real importance until the end, and this is an alternate Booker, so the only real connection to Infinite is Elizabeth ability to open Tears, and the basic gameplay controls. In a storyline sense, it's more like a DLC to the original Bioshock series.
  • World of Warcraft is like this at times. Events happen outside the game's continuity that still affect the game. Why is the king of Stormwind back for Wrath of the Lich King, and where was he? Why is Cairne dead in Cataclysm? Op, better read the expanded universe material to find out! To be fair, the games never leave you completely out of the loop, but you might have to dig for those tidbits. It's just the basics, not the complete story.
    • Blackwing Descent, one of the tier 11 raids, is home to Deathwing's son Nefarian, who is running experiments on different kinds of dragons. Except Nefarian was already killed several years prior to the Cataclysm expansion. Playing through the game alone, you'll never find out how Nefarian came Back from the Dead, what the purpose of his experiments was, or how they tied into Deathwing's plan since the raid doesn't address it and neither Nefarian nor his experiments ever appear or are mentioned outside of Blackwing Descent. Were it not for the Expanded Universe, the entire raid would be a Big-Lipped Alligator Moment.
    • Nozdormu, Aspect of Time and leader of the Bronze Dragonflight, was missing in action during classic WoW and the first two expansions. It was a bit of a plot point that the rest of his flight didn't know where he was or what he was doing. Then, in Patch 4.2, he shows up during the Elemental Bonds questline. No mention of him having been gone, where he was, or when he got back was made, and everyone just acts like there's no reason he wouldn't be there. Turns out his return was covered in the Expanded Universe novel Thrall: Twilight of the Aspects... Which, when 4.2 first launched, wasn't even out yet
  • The Kingdom Hearts series. Starting from any game from Chain of Memories and onward will get confusing. And no, despite what the marketing says, the series is a devout adherent of Oddly Named Sequel 2: Electric Boogaloo. No game in the series is unimportant, as the player is supposed to play the games in chronological order; playing just the three numbered games will get them absolutely nowhere. For example, Chain of Memories is actually a direct sequel of I and serves as the stepping stone between it and II; without it, the player will not catch even 10% of the latter game's plot (case in point: II opens with a set of characters the player don't know about living in place they don't know about and talking about things they don't know about but are probably related to I because there are flashbacks...or something). Birth by Sleep, by virtue of being a prequel, is probably the only sequel that newbies can pick up relatively mindfuck-free, but it contains many Call-Forward references that will fly over their collective heads unless they have played the preceding games. What's worse, the series is spread over 8 different consoles, including handheld onesnote , mobile phones, and web browsers. Crack Is Cheaper than playing the entire series.
    • It also doesn't help that the Final Mixes in the series are unavailable outside Japan, despite containing critical plot points. This makes it difficult to follow the already complex plot of the series, unless you look up fan translations.
    • Luckily, Square Enix released 1.5 worldwide for the PS3, containing KHI Final Mix, Re:Chain of Memories, and an abridged, cutscene-only version of 358/2 Days. Then they released 2.5, containing KHII Final Mix+,Birth by Sleep Final Mix, and an abridged version of Re:coded. Eventually, they released PS4 versions of both collections, after a third collection containing Kingdom Hearts 3D: Dream Drop Distance along with Kingdom Hearts 0.2: Birth by Sleep - A Fragmentary Passage and Kingdom Hearts χ as a movie, before the release of Kingdom Hearts III on PS4, ensuring that the entire series, absent playable versions of the DS games, is playable on one console.
    • Kingdom Hearts 3D: Dream Drop Distance had a recap-like "Memoirs" feature. The generally bare-bones entries and hyper-complicated plot make the memoirs more useful for fans needing a refresher, though.
    • The Disney worlds are supposed to be played on the assumption that fans have watched the movies they reference, because the worlds are abridged, modified, or start In Medias Res to fit the series narrative. The worst example in recent memory is Arendelle from III, which significantly cuts Hans' role, yet he (or rather, his Heartless) still attacks you at the end for no apparent reason.
  • The Ace Attorney series goes out of its way to avoid this, to the point of characters avoiding references to other games even when it would make sense to do so. See: Miles Edgeworth in Ace Attorney Investigations constantly mentioning that he no longer follows the von Karma way without mentioning the fact that von Karma murdered his father and raised him that way as revenge for a small courtroom slight... at least until the second Investigations game, which features Gregory Edgeworth's last case as a playable segment, but that was only released in Japanese and many Western fans haven't played it. He also refuses to ever refer to Phoenix Wright (who doesn't appear in the spin-offs outside of two hidden cameos) by name, which gets pretty hilarious after a while.
  • Continuity in The Elder Scrolls games works in a similar way to avert lockout. For example, you don't NEED to know about the Warp in the West to play and enjoy Morrowind — but if you'd LIKE to know how the previous game's multiple endings were resolved, just read the in-game book about it! Business and technical challenges sometimes force some bizarre contortions of continuity, but those are covered by other tropes.
  • Melty Blood assumes you already know all the characters and their relationships to each other. If you're completely unfamiliar with Tsukihime, it feels like a massive In-Joke.
  • The Legacy of Kain series is hard enough to follow even if you play them all. If you missed one, you have no chance. Well, you'll probably be alright if you miss Blood Omen 2: it gives some back story for the Hylden, but nothing terribly important that can't be gleaned from Soul Reaver 2.
  • BlazBlue takes the cake. Let's try and break down the storyline: no matter which character you play through the arcade mode with, each of them all end up having the same ending in which they just simply cannot stop the Big Bad from unleashing his ultimate creation and getting one step closer to destroying all existence. But the thing is, each of these character endings all happened at the same time, because the Big Bad is manipulating the laws of space and time to reset time over and over again, each time creating a new dimension in which he hopes the parameters will be just right where he can carry out his ultimate goal. Confused yet? It gets worse. On top of all those endings all happening at the same time, an overarching storyline continues to unfold in which each character has their own goals that they want to achieve. Some characters are just trying to live peaceful lives, some have become bounty hunters while trying to hunt down the most notorious criminal in the world, while he himself is just looking for someone's ass to kick, namely the Big Bad. One girl is trying to figure out who she is, and eventually finds herself as the very center of all the crap that is happening. Meanwhile, the bad guy is trolling each and every last one of them, manipulating many of them and corrupting their ideals, making friends distrust each other, betray each other, and pull everyone's strings to the extent that everyone is about to just go straight up crazy. Somehow the main characters figure out the plot, band together, and defeat the big bad, but this was all part of his plan to make what is a computer equivalent of GOD overlooking the entire universe to divert its attention long enough for the big bad to take it over and advance his plan yet again.

    All of that was the outcome of just the first two games alone. Read the character pages for the game and just see how many spoilers there are. It'll take a long while before you can start to make sense of it. It's not like playing the first game will help better explain anything either. You'll be just as confused if you just bypass the first game altogether and start with the second. This isn't even counting the numerous spin-off games for multiple portable platforms like the PSP and DS, assuming that the game even gets exported over from Japan in the first place!

    Worse still, there is an exorbitant amount of side materials which all manage to tie into the main plot. Whereas you could largely get by in Guilty Gear, BlazBlue's predecessor, without these, they are crucial to understanding the BlazBlue universe. For starters, if you want to know why Hakumen is the man he is today and how Hazama is able to prey on Tsubaki's jealousy of Noel, that's where The Wheel of Fortune drama CD comes in. The Phase Shift light novels build up the underlying story of the Six Heroes and details the exploits of the Dark War's unsung hero, a time-displaced Ragna the Bloodedge, not to mention that the fifth novel throws in a hook for the third game (namely that the Celica playable in Chronophantasma is a time-displaced clone of the original brought to the present by her niece Kokonoe, created when Celica touched the Cauldron in Ishana). Even the overly fanservicey Remix Heart manga might end up influencing things down the road given the main character's friendship with three of the games' more prominent females, her status as one of the Duodecim (the twelve families Jin, Tsubaki, and CP newcomer Kagura belong to), some rather Mind Screw-laden visions of the future in later chapters, and Mai's eventual connection to a powerful grimoire created by Nine of the Six Heroes. Luckily, members of the fandom have managed to translate and give synopses of these works, but if you don't bother doing your homework, you're going to have a hard time making sense of some of the more cryptic allusions.

    Central Fiction adds Naoto Kurogane, who was in the Bloodedge Experience light novels, Es from the XBlaze games, and Mai Natsume from the aforementioned Remix Heart manga (with her appearance based on the then-concurrent Variable Heart manga, which is a midquel set between Remix Heart and Calamity Trigger). If you haven't read Naoto or Mai's stories (most likely not, as they were Japan-only) or played both of the XBlaze light novel games, you won't realize why they're in the game, or even realize that Naoto and Es hail from separate Alternate Universes—connected to the main BlazBlue world via the Boundary—yet have direct ties to other members of the main roster (as versions/analogues of certain characters existed in their realities) and/or the real Big Bad's plot.
  • In Touhou, this wasn't much of a problem during the PC-98 era and the first few games of the Windows era, since the plots of those games were largely self-contained. However, after Mountain of Faith the Continuity Creep starts to take place, and now it's much more difficult for newcomers to understand what's going on since each game builds upon the previous one. Comments by ZUN suggest that he feels a certain level of inaccessibility is core to the Touhou experience. The various manga and Universe Compendiums don't really help either, since all the manga series assume that one is already familiar with the games and their lore and the Universe Compendiums have some Unreliable Narration at work. That said, since Touhou is at its core a Shoot 'em Up series and the shmup genre is known for its heavy focus on gameplay over lore, if you just want a series of Bullet Hell games, you don't need to understand the plots to have a good time.
  • Mass Effect:
    • Happened with Mass Effect 2 when it was ported to the PlayStation 3. Because of licensing issues, the first game couldn't come to that console, until the Mass Effect Trilogy arrived five years after the first game's release. People were worried that new players wouldn't get the whole story, so BioWare created an interactive comic that, admittedly, tells the story from a somewhat awkward perspective. It glosses over Feros completely, leaving some players in the dark about Shiala, the Feros colony, et. al. Even worse, as Admiral Hackett doesn't appear in the sequel outside of passing mentions and a letter, his significance in the Arrival DLC is completely lost on players who didn't experience the first game.
    • Averted in Mass Effect 3 with the DLC plots from Mass Effect 2, as the game has alternate scenarios in place if the player didn't do the DLC missions. For example, Shepard is incarcerated at the start of the game for working with Cerberus rather than causing hundreds of thousands of batarian deaths, as the situation in Arrival is handled instead by Alliance soldiers and Liara defeats the Shadow Broker with a ton of hired mercenaries.
    • There are two small cases in the second and third games. Unless you've played Mass Effect: Galaxy, you won't know how Jacob knows Ish on Omega. People who haven't read the novels also won't know where Kai Leng came from.
  • Anyone playing Super Robot Wars OG Saga: Endless Frontier EXCEED would be left confused if they did not first play Super Robot Wars Original Generation Gaiden, as two characters in the playable cast who were supposedly Killed Off for Real in the main series winds up in the spin-off series. In fact, the developers make it a point players must play the previous games occurring in main continuity to know what's remotely going on if they decide to start somewhere in the middle.
  • Playing a LEGO Adaptation Game, apart from the Lego Batman games (which are original stories) and the Lego Marvel Super Heroes game (also original), make very little sense if you haven't seen/read the source material they are based on, as this blog demonstrates.
  • Metroid: Other M is frequently accused of this. While most of the references make sense to a casual fan, the use of this trope single-handedly turned the Ridley scene into one of the most despised scenes in the series history. This plot point came from an obscure manga that was never released outside of Japan, where Samus has already feared Ridley since he killed her mother and led a massacre of her home planet K2L. About the only indication people get is a nonsensical shot of Samus turning into her child self, rather than actually showing the ravaging of K2L for context.
  • It is possible to understand and enjoy the plot of Suikoden III without playing the first two games in the series, but the reveal of the Masked Bishop's identity (a pivotal moment in the story) will not make any sense.
  • Batman: Arkham Origins suffers quite a bit from this, as there are a lot of references to old Batman stories (most notably, when Joker flashes back to his Red Hood costume from The Killing Joke) that are pure fanservice to old hands make no sense whatsoever to new players. Though The Killing Joke segment takes place entirely in Joker's head, so it doesn't have to make much sense.
  • Saints Row IV has many missions and jokes that refer back to the previous games, especially Saints Row 2. If you haven't played those earlier games, the significance of certain events is decidedly lost (especially since Saints Row was exclusive to the Xbox 360, meaning a large section of the fanbase hasn't played it). Amusingly, Saints Row: The Third was supposed to be an aversion, barely bringing up the Stilwater adventures so as to not alienate new players.
  • The Warriors tries to avoid this - and mostly succeeds - both by recreating the opening scenes of the 1979 film at the very beginning (although some crucial dialogue is edited out) and by making the game a prequel of sorts, beginning about a year (1978) before the events of the film and firmly establishing the personalities of the nine major characters long before the actual content of the movie becomes playable. The numerous cutscenes, heavy chunks of dialogue and constant updates on the radio (the gang has one in their training studio) by the famous lady DJ about what's happening throughout the city help a great deal.
  • The Zero Escape franchise has an up-and-down relationship with this. The first sequel, Virtue's Last Reward, more or less tells its own coherent story, although a couple of characters will only be fully understandable with having played the first game, Nine Hours, Nine Persons, Nine Doors. The final game, Zero Time Dilemma, instead commands fairly intimate knowledge of both previous games in order to make any sense of what's going on.
  • A comparatively minor example in Fallout: New Vegas, but the Courier will have a hard time answering the questions to prove you're an NCR citizen without having played Fallout and Fallout 2. The only question you can answer based on what's in New Vegas is the one that asks what's on the NCR's flag. The answers to the other two questions, which ask what the NCR's original capital city and its most popular president are, are not found in game.
    • The villainous nature of the Enclave in Fallout 3 can seem odd without having played the previous game, Fallout 2. To a new player, the Enclave is simply the remnants of the American government who provides patriotic music and occasional radio broadcasts on their radio station (at least until they kill your father and take control of Project Purity). However, Fallout 2 revealed that the Enclave is the descendants of an elite billionaire class secretly running the American government, incredibly human-supremacist, and wants to eradicate all radioactively mutated beings from the Wasteland, which in Fallout 2 includes most of the people living in the Wastes, but is relegated to just Super Mutants and Ghouls in Fallout 3. (Knowing this also explains the psychopathic experiments of the Vaults - Vault-Tec was run by members of the Enclave, and was intended as a proof of concept that humans could survive under various, often torturous conditions (including isolation, radiation, artificially created caste systems, and so on) to later be used for space flight. Without this knowledge, however, most Vaults and their experiments will seem more like mad science run rampant than for an actual, if not completely justified, cause.) However, this backfires, as it's never really explained how the Enclave could exist in D.C. if they'd all been evacuated to an oil rig off the coast of California soon before the bombs fell.
    • The sudden appearance of the Prydwen and the Brotherhood of Steel in Fallout 4 can appear as a Deus ex Machina without having played Fallout 3. They're only mentioned in the game before this if you manage to listen to the easy-to-miss military signal and rescue Danse and his squadron at the Cambridge Police Station, and the Power Armor helmet on the front is implied to be the player's Power Armor, not belonging to the Brotherhood like on the covers of Fallout and Fallout 3. Then, after completing Act 1's boss battle, the Sole Survivor emerges from Fort Hagen to see a giant airship and several Vertibirds flying around, announcing the Brotherhood of Steel's presence to the Commonwealth. While most companions are at least familiar with the Brotherhood (Danse and Mac Cready the most), Codsworth, the Sole Survivor, and any new player will be thoroughly confused.
      • Similarly, Madison Li's side quest to rejoin the Brotherhood of Steel is rather nonsensical without playing Fallout 3. In Fallout 3, she works with the Brotherhood of Steel to finish Project Purity. However, in the 10 years between games, she makes her way to the Commonwealth and eventually joins the Institute, which is where the Sole Survivor finds her. The Brotherhood's motivations for wanting her back hinges on the player's knowledge of this - otherwise, it seems like they threw a dart at a board of Institute scientists and chose her.
  • Zigzagged with the Neptunia series. The canon games (the ones that further the storyline) open with both Narration and one of the main characters Breaking the Fourth Wall to explain how the world works, who the main characters are, important plot points from previous games, etc. The non-canon spinoff games, on the other hand, seem to expect you to have played the canon games and know who the characters are, since they liberally use concepts and terminology from The ’Verse with little explanation.
  • South Park: The Stick of Truth generally averts this; despite being full of Continuity Porn, most references to the show are more or less used as one-off gags that don't impact the plot to a significant degree. South Park: The Fractured but Whole, on the other hand, has its plot so closely integrated with the show (especially seasons 19-21, the most recent three at the time of the game's release) that the vast majority of the jokes and references that the plot relies on will end up completely lost on those who haven't been following the show religiously.
  • The Witcher games zigzag this trope on account of serving as a continuation for a series of books that were virtually unknown outside of Poland for the longest time. The first game manages to avert through the process of making Geralt an amnesiac who doesn't remember what happened in the books. This has the effect of turning him into an Audience Surrogate who's as familiar with the world, characters, and backstory as the player is. The sequels, however, play it more straight. On top of building upon the games' ever-growing narrative, characters and story elements from the books become even more prominent, making it all the more imposing for newcomers to jump in.
  • The Kiseki Series can easily fall into this trope. While each series has a more or less self-contained plot taking place in different countries across Zemuria, there are many, many side characters from other parts of the franchise that make extensive cameos and references to other events. Each of these games is a 60-100 hour RPG with tons of dialogue, making catching up a daunting task. The games set in Crossbell are an enforced example thanks to not being localized yet, it doesn't help that several characters from Zero/Azure are referenced, and the protagonists from those games are even briefly playable, not to mention some other Crossbell casts making their appearances in the third Cold Steel game, making players wonder who the hell these people are.
  • Deltarune more or less takes this to its logical conclusion, making it absolutely a necessity to have played Undertale first. Not only are you expected to recognize the characters, since most of the demo's "hook" comes from seeing familiar characters in a very different setting, but the fact that you, personally, have played Undertale is a plot point; you can make references to the previous game that the character you're controlling has no reason to know about, and this is even noticed in-universe. Further, the final scene, while startling enough on its own, is truly disturbing to players who recognize just what's going on.

    Web Animation 
  • Homestar Runner. It's not a very continuity-heavy site really. But there is large reliance on in-jokes and running gags. The toons are sorted in to different categories so you're not even sure where to start. However, it has a wiki that is so helpful and comprehensive... it's a little scary. This is the only place you'll find a chronological list of the toons and games.
  • The Transformers: Combiner Wars manages to do this despite being set in its own exclusive continuity and only a half hour long. It constantly flings about references to prior Transformers lore without ever stopping to explain what it all means. Even worse, Transformers is a franchise that relies heavily on alternate universes and continuities and elements vary greatly from series to series, meaning even hardcore fans had trouble telling what was supposed to be going on.
  • The Most Popular Girls in School: The number of views of each consecutive episode on YouTube decrease sharply because of this trope; this comedy series had evolved into a plot-heavy Dramedy by the start of Season 3.
  • Dr. Havoc's Diary: Just like Mark and Carlo's first show, you really need to keep track of the continuity regarding Dr. Havoc's misadventures, or else the plots and jokes will make little sense.
  • Sonic for Hire was very reliant on continuity. The first season was easy to follow, in which Sonic just simply tried to find work to get out of being broke with Tails' help, and only had a few moments of continuity here and there. It wasn't until the season finale where Sonic gets turned into an eggplant that the series began requiring the viewer to keep track of everything that goes on, regardless of if it was plot crucial.
  • Pokémon Rusty, despite being a Black Comedy parody series of the Pokémon franchise, had virtually no standalone episodes whatsoever, with each episode featuring either a Call-Back or a Continuity Nod to something that happened prior with little-to-no explanation.

    Webcomics 
  • Sluggy Freelance. Trying to understand the significance of things without going through an Archive Binge... just doesn't work. Sluggy Freelance may be the only webcomic where the creator forgot his keys and locked himself out of his own continuity. In his defense, the writer has become aware of this trope and provides relevant links at the bottom of the strip for anyone who hasn't gone through the eight plus years of continuity.
  • Megatokyo. If you haven't read it from the beginning, you can forget about understanding the story. This is largely due to its character driven nature. If you haven't witnessed every second of Piro and Kimiko's courtship, or taken notes on each tiny nuance of the Piro/Miho dynamic, you aren't going to have any clue what's going on. Even then you might still have trouble, but that's another trope entirely
  • Dominic Deegan, making the sheer dedication of the Hatedom all the more puzzling.
  • Penny and Aggie is a tapestry of numerous characters and subplots and overarching plots and rivalries... just read it from the beginning and you'll understand it better. The website now attempts to help those not planning on an Archive Binge by displaying a summary of the current plotline and the characters involved. The reader is still missing out on a wealth of backstory and characterization if they rely on that alone.
  • Scary Go Round was brought to an end due, in part, to its massive archive keeping new readers at bay. The following strip Bad Machinery is set in the same world, but with new characters, two supporting characters, and some other characters from Scary Go Round for which backstory is not needed to understand their new role.
  • Girl Genius has so many characters who can be summarized as "Mad Scientist", many of whom disappeared for several years and then resurfaced, that even after reading the entire archive it's hard to keep track of what's going on now.
  • Gene Catlow has spent many years on a single, complex arc that seems to have important roles for dozens of characters.
  • Any MSPaint Adventure, but particularly Problem Sleuth. Even people who have read every single page in order occasionally need to sit back and think "Wait, what's going on?" If you have a good grip of the story, even skipping a few pages will mean you won't understand a Call-Back or five.
    • Generally, webcomics having call backs isn't so rough because of their archives, but MSPA is one of the few webcomics (except, perhaps, the Walkyverse) that requires you to read unrelated webcomics to get all the jokes. Want to understand why Jade is making jokes about pumpkins in Homestuck? What's up with Ace Dick's extended sideplot in the Game Of Life? Well you had better read every badly-drawn, nonsensical corner of Jail Break!
    • The author acknowledged the need for think-time during Problem Sleuth by having not one, not two, but three recap comics throughout its run, the first of which is simply devoted to explaining where everyone is and how many versions of each character exist.
    • Homestuck, Problem Sleuth's successor, has a very very very very very convoluted plot. One can spend hours trying to fit all the pieces together, and chances are that you've probably still missed something that the fandom hasn't. And then there's the tangentially related pages such as the Midnight Crew and Sweet Bro and Hella Jeff, which somehow weave through and permeate the entire plot even though they're in rather... inaccessible locations.
    This link is the in-comic recap of the first year.
  • Eerie Cuties/Magick Chicks:
    • It was originally intended for newer readers to be able to follow Magick Chicks without it being necessary to read both comics. But between their Shared Universe, two major crossovers, along with several cameos and certain events overlapping, they became so intwined that it was no longer possible.
    • The writers eventually realized it themselves, which lead them to do a "soft reboot" of both series, to make things easier to follow.
  • The Order of the Stick is not quite long enough to invoke this yet, but it's well on its way there, as any strip past the 300-strip mark has a 80% chance of making no sense whatsoever to anyone who hasn't read through the whole archive. It's exactly like joining a RPG campaign in the middle: you'll still get the gamer jokes, but who are all of these NPCs?
  • Occasionally there are Arthur, King of Time and Space strips that don't make sense unless you know the running gags and continuity points. As with many meta-concepts in AKOTAS, Lampshaded via Arthur's webcomic.
  • Unwinder's Tall Comics: author Eli Parker calls attention to it in The Rant for page 121. "I was doing such a good job of producing comics that were newcomer-friendly, and then I had to go and do this. I apologize to any newcomers who showed up and saw this."
  • El Goonish Shive: Author Dan Shive tries very hard to avert this but he has lampshaded it in the past like in this comic's title or this one's commentary. Like Sluggy Freelance, he has taken to providing relevant comic reference links at the bottom of the strip just above the commentary for anyone who hasn't gone through the ten plus years of continuity recently.
  • Wapsi Square has been running since 2001, has over 2000 strips, and has heavy enough continuity that you can't merely skim read if you want to be able to understand what is going on.
  • Given the sheer amount of content within Endtown, this is bound to happen. Fortunately, you can go on an Archive Binge, but a person who starts reading now would be most likely confused.
  • Stand Still, Stay Silent: Events connected to each other can happen real-time months apart, to the point that even some of the regular readers can forget a given event happened by the time it gets a follow-up, so things can be even harder to understand for someone just jumping in on the latest page. This comes with the fact that some basic information given about the characters upon their respective introductions is both very seldom mentioned afterwards and relevant throughout the story. A lot about the background has also been filled in by Word of God in the page comments themselves, resulting in statements pre-dating the time at which one has started reading sometimes ending up buried in hard to find places.
  • Nineteen-Ninety-Something spawned over 1000 strips in a span of 2 years, and despite being an homage to Newspaper Comics of the 90s, it's jet-packed with tight continuity that would only make sense if you've read the previous story arcs.

    Web Original 
  • Given the vagueness of the plot and the fact that all the episodes are online, lonelygirl15 would probably not be an example of this, if it wasn't for the tendency of seemingly irrelevant, blink-and-you'll-miss-it background details to become crucial Chekhov's Guns several hundred episodes later.
  • Happens in Survival of the Fittest a great deal. Sometimes, even starting at the beginning of the current version/season isn't enough — references will be made to scenes or characters in previous versions. It's often very bewildering for people seeing the RP for the first time.
  • Arguable with the Whateley Universe, since it now consists of over a hundred stories, most of them novel or novella length. Every major protagonist has a backstory, and girls of Team Kimba all have backstory novels. Diving in with current stories means you may not get the in-jokes, or the references to prior stories, or what's going on with recurring characters, or some of the ongoing plotlines, like Ayla's blackmailer or Jade's quest, or the people who may be after Toni. It's assumed that you already know what the main characters' powers are.
  • Also arguable, That Guy with the Glasses, especially with how many multi-video running gags, crossovers, story arcs, and callbacks to past videos they use. Most hardcore fans of the site were lucky to find the The Nostalgia Critic's stuff on YouTube before it grew into a critic community, so they have a leg up on knowing each Running Gag. Watching individual reviews on the site, it seems fairly accessible, but understanding something like Kickassia is impossible unless you have a good understanding of the group's dynamic, and the use of past characters.
    • Linkara is definitely one of the worst with his ongoing story arc, but to his credit, he has posted on his own website every arc-related episode in chronological order. There's also a more recent recap video. His storyline being intimately intertwined with Spoony's doesn't help.
      • Made even worse by Spoony no longer being on the site. Newcomers won't be able to follow it anymore unless they do some off-site research.
    • Suburban Knights was specifically written to avoid this, however. You'll definitely get more out of it if you're a fan of the site (especially regarding the use of Ma-Ti) but the story is perfectly comprehensible to someone coming in cold.
    • To Boldly Flee wasn't shy about being a Continuity Porn send-off for The Nostalgia Critic, but you needed to know his issues and backstory, Spoony spooning everyone, Linkara's running at the time Story Arc of getting worse as a person and the Psychotic Love Triangle between Chick, Todd and Lupa.
  • Ostensibly, one of the reasons Rooster Teeth ended Red vs. Blue: The Blood Gulch Chronicles at Episode 100 was to prevent Continuity Lockout. While they succeeded, the series from that point forth became more plot based, and a good number of the Call Backs still require familiarity with all the older episodes (as opposed to just episodes from the most recent trilogy, Recollection).
  • The Slender Man Mythos is slowly becoming this, particularly Everyman HYBRID with its Alternate Reality Game elements and the miscellaneous Core Theory blogs. Aggravated by the occasional Dead Link.
  • The Unshaved Mouse's love of Running Gags and story arcs can cause this for new readers who don't start reading from the very beginning and wind up scratching their heads over why "Bahia" is mentioned so often or why there are all these talking maps of continents around. He lampshaded it in his Fantasia 2000 review in which a lengthy sequence of him being put on trial by a vengeful Comrade Crow with Antarctica as his attorney (a subplot that was set up two reviews earlier in Mulan) was followed by a photo of a confused reader with the caption "I just came to this blog because I was told there were Disney reviews here and I have no fucking idea what all this bullshit is."
  • Discussed Trope in The Comics Curmudgeon, where Josh criticises a B.C. strip for being totally incomprehensible to new readers, before realising that he came into BC late enough that the Running Gag in question was never actually explained to him either, but he picked it up somehow. He then follows it up with "a couple of comics and commentaries thereupon that probably won’t make any sense if you aren’t a regular reader of this blog!" (One about Kaz's "sex dojo" in Gil Thorp and one about "Finger-Quotin' Margo" in Apartment 3-G.)
  • The Black Guy Who Tips: Since all but the last ten episodes are behind a paywall, most of the show's injokes and references are lost on newer listeners. (Example: You would have to be a regular listener since 2013 to know what "The Dudebros" is all about). Though Rod and Karen will occasionally re-explain some things (Like what "Bulletball" is).

    Western Animation  
  • One of the many complaints people had about Beast Wars is that when it aired, it had the strongest continuity ever seen in a cartoon on American or Canadian TV. As a result, a new viewer jumping in partway through is going to be quite perplexed by what's all going on. Then its sequel Beast Machines one-upped it.
    • Ironic with Beast Machines, since they were originally trying to avert this trope by ignoring most of Beast Wars, only to end up with a stronger version of the trope in its own series.
    • Transformers Prime ran into similar issues. There's one episode fairly late in the series' run that references nearly every episode that had come before it in some way, ranging from what an item in the background is to why one of the characters is a zombie now; TFWiki.net continuity notes begin by saying that this would be a tough episode to start watching the series. This may be why its sequel is using more of an episodic Monster of the Week approach. However, some knowledge of The Movie Grand Finale of Prime is required to explain why Bumblebee is speaking to the spirit of Optimus Prime in the early episodes of the series. While it is possible to follow coming in cold, this holds more significance for those who have seen the later episodes of Prime before this series; which connects the two.
  • Star Wars: The Clone Wars was often comprised of episode arcs rather than as a typical serial. For casual viewers, missing a new episode could lead to getting confused if they don't recover and instead choose to continue to the next episode without context. This actually ended up being a problem for the show's ratings over time in combination with the Cerebus Syndrome (meaning it turned away younger viewers, who are the target audience since the show aired on Cartoon Network), which eventually led to the show's cancellation before the Disney buyout. This is why its sequel, Star Wars Rebels, tends to avoid arcs and seeks a balanced Cerebus Syndrome that won't turn away the younger audience as time goes on.
    • You may still be locked out of Rebels however, especially if you've never watched The Clone Wars due to continuing off of characters and plots from that, such as Ahsoka Tahno, Rex, Gregor and Wolfe the Clone Troopers, and a very alive Darth Maul. Also, Rebels is also similar to its predecessor in that every episode counts towards something later on, no matter how how small or big the impact is.
  • Later episodes of The Simpsons suffer from a mild case of this condition at times (though it's understandable for a series that is about to begin its 30th season). One particular gag in the ninteenth season's "E. Pluribus Wiggum" involved Homer (accurately) daydreaming about a "think-tank", a joke which is probably funnier to longtime viewers than new ones unaware of his bizarre Imagine Spots.
    Homer: (noticing the rest of the family staring at him) What, I'm not allowed to get one right?
    • Many of The Simpsons' minor characters are completely bizarre without context, yet the show takes it for granted that the audience can recognize and appreciate most of them without any sort of perfunctory introduction or explanation. Examples would include Bumblebee Man, Sideshow Mel, Duffman, the Sea Captain, or Disco Stu, or even Krusty, all of whom are long-running continuations of one-off gags from many, many years past. One gag even relies on the viewer recognizing Duffman's voice, when he himself neither appears nor even gets mentioned in the episode.
      • This is Lampshaded when Marge gets amnesia in the seventeenth season's "Regarding Margie". She finds all the side characters confusing and creepy and is incredibly disturbed when Homer says they're his and Marge's close friends.
    Marge: (off Otto Mann) Why is that drug addict driving a school bus?
  • The Avengers: Earth's Mightiest Heroes! has subplots that span several episodes, or start off one week and get picked up again much later. The second half of season 2 was mostly changed to stand-alone episodes, as Marvel TV head Jeph Loeb claimed that the show's mediocre ratings might have been the result of the series being inaccessible to new viewers. Even then, viewers jumping in at this point would probably still feel confused.
    • This was then used as part of the justification behind ending Earth's Mightiest Heroes and launching Avengers, Assemble! as a replacement.
  • Phineas and Ferb might have a bit of this, given how much of its humor relies on Continuity Nods and playing with their usual formula. Still, this affects plot less than gags.
  • There's are no fewer than six episodes of Codename: Kids Next Door that start off with the KND trying to steal the birthday cake of the Delightful Children From Down The Lane with no explanation for a new viewer as to why exactly the DCFDTL are supposed to deserve this. Included in the six are the first episode, and the final episode.
    • Aside from this episode, there are many episodes that continue off of each other, numerous Myth Arcs, newly introduced KND members, and other organizations or subfactions of the KND themselves.
  • ThunderCats (2011) is heavy on its Heroic Fantasy plot, but this makes it fairly difficult to leap in halfway and know what's going on. Some episodes don't really end as much as they just stop, only to pick up right where they left off the next week, which lends to the show being more accessible in large chunks.
  • As the Ben 10 franchise went on, it became harder for audiences to become invested in the arcs and growing cast of characters. The fact that the films and crossovers that the franchise have spawned are all canonnote , meaning that those disinterested may have to watch them anyway. Ben 10: Omniverse promised to be a good starting point, though it still required a good deal of understanding of the three previous shows to understand jokes, characters, and even certain story arcs. Omniverse's poor ratings led to the franchise being rebooted with a new continuity a few years later.
  • Like Thundercats, Young Justice also falls into this. The second season even more so due to much larger cast and regularly jumping around to accommodate them.
  • For that matter, Green Lantern: The Animated Series falls under this starting with the Manhunter and Anti-Monitor arc in the second half. That's pretty impressive for a series that only lasted 26 episodes.
  • The Venture Bros. series creators, Doc Hammer and Jackson Publick, actually discuss this trope when they hosted the season four finale Operation PROM on [adult swim]. They appeared in a series of videos leading into and coming back from commercial breaks during the initial airing of the episode, and in one of them, discussed how self-referential this episode in particular was. The series in general, at least after the first season, can have this effect as well, as the episodes are packed with references to things that happened previously, not to mention that it gets weirder and weirder with each passing season.
  • Total Drama has been getting less and less elaborate on its past as the series goes on. The latest season, All Stars, begins with no real recap of any of the show up to that point (aside from the characters quickly bringing up certain moments), so anyone who hasn't seen the episodes beforehand would be much more confused than those who had, which makes sense because PSN does not have the Island special, all of Action, and all of World Tour, creating weirdness concerning Sierra's crush on Cody, and Alejandro being in a robot suit among others.
  • Avatar: The Last Airbender and The Legend of Korra suffer this problem due to having detailed storylines in a complicated universe, with every episode either moving the plot forward or developing its increasingly complex main characters. This is especially true for Korra, which unlike its Myth Arc-driven predecessor, is heavily serialized, with each season-long story arc directly leading into the next and Previously On segments only explaining what happened on the prior episode alone. People who watch the show casually or missed early episodes may be lost later on, when things get heavy and the characters are well-established.
  • With each episode of Detentionaire, the plot becomes more and more intricate as either new characters are introduced, old characters change, or some important plot point is revealed. As a result, jumping into the series without starting from the beginning, or missing one episode entirely, could result in a lot of confusion as to what is occurring, even with the recap at the beginning of each episode.
  • Gravity Falls was pretty tightly packed with continuity, especially during it's second season. The series had long-running plot arcs concerning mystery objects, major changes that tend to avert Status Quo Is God, and important call-backs that could be confusing for new viewers. Although season one was largely stand-alone, it still had episodes that introduced characters or certain plot-elements that would reappear or become important later on. It's not so bad that some of the show's younger audience may not be entertained just by the jokes and the action elements of the plot, but the show's older Periphery Demographic is unlikely to include anyone who hasn't watched it from the first episode, and the Grand Finale is completely inaccessible for anyone not familiar with the show.
  • Apparently Lauren Faust wanted a season-long story arc about Nightmare Moon in My Little Pony: Friendship Is Magic, which the higher ups vetoed specifically to avert this trope. The series eventually moved away from this, with later seasons having such story arcs.
    • "The Super Speedy Cider Squeezy 6000" wasn't aired in the UK, due to cider more commonly meaning hard cider there, causing some confusion for viewers who only watch the show on TV when Flim and Flam reappear in later episodes.
    • Word of God states that while the events of the comic book series and My Little Pony: Equestria Girls are canonnote , references to these works are explicitly avoided in the main show to prevent this trope.
  • With each passing season of Littlest Pet Shop (2012), protagonist Blythe Baxter continues to move up in the fashion world and becomes increasingly famous, and those seasons' episodes that focus on that aspect of her are written with her then-current status in mind. There are also a handful of episodes that have the Biskit Twins as the antagonist with no explanation given as to why they are the Designated Villain; knowledge of their repeated attempts to sabotage Blythe is required.
    • There is an episode in Season 2, "Blythe's Big Idea," which exists solely to set up the rest of the season. This includes the introduction of the Pet Jet (which allows Blythe to travel to other countries, which would become a recurring theme from then on), Blythe acquiring her kiosk store, and details about the Pet Fashion Expo to be used in the season finale.
    • Season 3 also gets a Mid-Season Twist: Blythe's best friend, Youngmee, has been clued in to Blythe's ability to communicate to animals. Season 3 also had a case of continuity lock-out that, due to the episodes airing Out of Order, inflicted this upon everyone following the show as it premieres: At the end of Season 2, the Biskit Twins' butler, François, was fired, but he was suddenly back with them early into Season 3. It turns out that the Christmas Episode had François re-hired to serve the family, but this episode was pushed back to, unsurprisingly, the holiday season and was skipped during the season's initial run. Hence, every viewer who saw him suddenly back were confused as to what happened.
  • This happens to a certain degree in Adventure Time. From season 3 onward, the show starts to do more world building, character arcs, and building up a continuity with very deep lore. One could still watch many episodes with little to no context, but to really enjoy the series, one must either have a good knowledge of the lore of the Land of Ooo, or watch the whole series from the beginning (which, given that the show was on the air for 8 years, could take a while).
  • Steven Universe is developing what's perhaps the most continuity-heavy cartoon series since the above mentioned Beast Wars. With only eleven minutes per episode, the show tells an increasingly dense narrative by bringing up small details that get referenced and expanded upon with the expectation that the viewer will recognize and connect previous foreshadowing in a show that just doesn't have the time to recap them.
    • The first half of season one isn't too bad as it's episodic enough that watching in broadcast order isn't strictly required to understand the premise; Steven is a young boy with magical powers that come from a pink quartz gem on his belly button and has adventures fighting Gem monsters with his maternal family of guardians called the Crystal Gems. Everything after "Mirror Gem" however, and you'd better have a working knowledge of the show's mythology to grasp the significance of characters' actions.
    • After season one, if you've not seen every episode by this point, you're going to be lost as the show expects viewers to recognize locations and plot points that might have only appeared once, dozens of episodes previously. It's to the point where most fans suggest newcomers not to watch Cartoon Network, as it's all too easy to be highly confused by random episodes.
    • For example, season three features its premiere two-parter reintroducing the watermelon Stevens, the Malachite fusion of Lapis Lazuli and Jasper fully formed and emerging from the ocean, Steven's empathetic powers and mental contact, the Alexandrite fusion of all three of the Crystal Gems, and the threat of the Cluster hatching in the Earth's core, the last of these being the only event to feature a back-to-back plot.
  • Understanding the plots of some episodes of Star Trek: The Animated Series requires having seen at least the majority of Star Trek: The Original Series, as several of them allude to the events of the original live-action series, such as Cyrano Jones' first encounter with the crew of the Starship Enterprise and Harry Mudd being asked how he escaped from his imprisonment at the end of the original series episode "I, Mudd".
  • Regular Show has fallen into this. Seasons 1-3 were pretty much stand-alone, but the premiere of Season 4, "Exit 9-B", involved almost every character who appeared in the show to that point. It arguably got worse with seasons 5 and up, with many episodes involving characters returning, and ongoing story arcs. There are still enough stand-alone episodes so it's not that bad, but to get the full experience you'd have to watch the earlier seasons (or at least the relevant episodes).
    • It got really bad with the UK airings of "Merry Christmas Mordecai" and "Sad Sax". The UK gets the episodes a few months after they first air, but since Cartoon Network UK will only air Christmas episodes around Christmas, when they got to that point in the season, they skipped over MCM and went right to Sad Sax, despite the fact that Sad Sax is a direct sequel to MCM, likely confusing some viewers.
  • South Park for the most part, was very light in continuity, with at least one Half-Arc Season. Then along came Seasons 18 and 19, which have ongoing season-specific storylines yet still maintaining episodic plots, with Season 18 having a Bizarro Episode with an ending that has no bearing on the rest of the series. Season 20, however, is all Four Lines, All Waiting, with every episode dealing with continuous subplots spanning across multiple episodes like a gender war, a regular character becoming a notorious Internet troll, a Romance Arc, and the 2016 presidental election. Season 21 tones this back down reasonable levels, as the episodes stand alone for the most part, and Mr. Garrison more closely resembles Donald Trump and isn't referred to by name, likely to minimize confusion to new viewers.
  • People watching The Loud House who missed the first Christmas Special might be wondering why Mr. and Mrs. Loud are no longer The Faceless in later episodes.
  • In The Venture Bros., the cause of Dean's emo phase through the fifth season was explained in the Halloween special which aired before it. Not helped by the fact that the special is included on the season box set as a bonus feature, meaning a lot of people will watch the main season first.
  • The Amazing World of Gumball was never a continuity driven show to begin with, but there are more than a few episodes that have some lock-out if you're not totally familiar with the series (such as "The Finale", which had just about every Call-Back to all the times the Wattersons have caused some sort of damage to the city or a character in particular, and "The Shell", in which Penny breaks out of her shell, reveals herself to be a shapeshifting fairy, and finally becomes Gumball's girlfriend).
  • Danny Phantom had a bit of lock-out in its second and third seasons, particularly in regards to Danny receiving new powers (such as his ghostly wail and cryokinesis), the introduction of new characters (like Dani Phantom and Frostbite), references to previous episodes, Valerie Grey's story arc, and Vlad Masters becoming the mayor of Amity Park (much of the confusion in the third season, however, could at least partially be blamed on Nickelodeon's airing staff, as the episodes wound up premiering out of order with no regard to Story Arc).
  • An interesting case with Archer. While the over all plots of most later episodes can be viewed and understood without having seen earlier episodes, much of the show's jokes are call backs and references to previous running jokes (such as Archer asking "why aren't we doing "phrasing" anymore?") or require long-time understanding of each character's foibles to get the full humor (such as Pam's history as an underground pit fighter/drag race champion). So while someone jumping in late in the show will have a basic understanding of what's going on, they may wonder what the joke is supposed to be when Archer keeps saying "danger zone".
  • Rick and Morty is a unique example; given the nature of the series. While it is still possible to enjoy most of the jokes on their own; all three seasons so far have stories that connect in some way or another, despite its episodic story structure. Notably, the season 3 premiere does make a fairly entertaining episode on its own; though humor does require knowledge of the character dynamic and how subtle details from previous seasons become key to the story. This can largely be attributed to how many events and lines, no matter how insignificant they may seem at first glance; play a part in the show's Myth Arc.
  • Explicitly lampshaded in the Aqua Teen Hunger Force Big Damn Movie. The opening musical number tells you upfront that the movie is celebratory affair with a lot of Continuity Porn, so if you haven't watched the show you'll be totally lost. It also gently deconstructs this a bit, pointing out that if you're jumping in this late and skipping all the previous episodes, you really have no one to blame but yourself for being confused.
    "Do not explain the plot! If you don't understand, than you should not be here!"
  • Hey Arnold! The Jungle Movie is very heavy on continuity, even picking up from where the intended finale of Hey Arnold!, "The Journal", left off (granted in a dream but still). As well as containing callbacks to several previous episodes of the series. Older fans will likely love it, but those just joining in without proper knowledge might be a bit confused considering the real life 13 year gap between this and the series. Especially considering the show only airs on TeenNick now, which not everyone would have access too and if they do, it airs during hours in which most people would be asleep. Some reviews have stated it was probably a good thing The Jungle Movie didn't go to theaters for this reason (ironically enough) as the movie that did was more a standalone adventure.
  • When making the move from Cartoon Network to Netflix, Dragons: Riders of Berk had to leave behind its Cartoon Network seasons and start fresh as Race to the Edge. Even though the setup deliberately tries to be fairly self-contained, it is still a continuation of the previous show and references to past events may go over the heads of fans who only started watching from Netflix.
  • While Ready Jet Go! is not a heavy story arc-driven series like Beast Wars or Steven Universe, it does have continuity. If you stumble upon a random episode, you may think that the Propulsions are a weird, stupid human family when they are really aliens. And if you do discover that they are aliens, you may wonder why they need to keep their identity a secret, or why a little kid in nerd glasses is spying on them.
    • Face 9000 gets an upgrade in "Face on the Fritz", so new viewers who see a post-FOTF episode, and then see a pre-FOTF episode might be confused.
    • Word of God says that Mindy will turn 5 in season 2, and will go into space. Most likely, fans who watch an episode where Mindy goes to space, and then watch an episode where Mindy stays on Earth will be confused.
  • Amusingly lampshaded in Justice League Action; a major plot twist towards the end of season one reveals that the show is actually set in the same universe as Green Lantern: The Animated Series and the Space Cabbie’s AI assistant is really an amnesiac but still alive Aya, unconsciously searching for Razer. The significance of the scene where this is revealed will probably go completely over your head if you haven’t watched Green Lantern, so the show has the Space Cabbie say exactly what such viewers are probably thinking (“Well, that was weird”), with an implicit assurance that it will be explained later.
