Everything we've been saying for two years about what's to come, is now all here on the screen.

Entries in a continuity based serial that have no bearing on the main plot, doesn't significantly alter the dynamic, and generally serves to knock off another entry. Could be considered {{Padding}} applied to a whole franchise.

Extremely common in {{anime}}, where nearly every show with 26 or more episodes per season will end up employing it to meet contractual demands. Filler is usually something entirely original for the anime, but it isn't always the case; many manga employ filler just as ruthlessly. Sometimes entire filler {{Arc}}s are created, most often because the series OvertookTheManga. Almost any long-running manga-based anime action series will tend to have gargantuan amounts of filler, because the Japanese networks, unlike western ones, pretty much don't do reruns or season breaks at all. This especially gets compounded when they go beyond the 26 episode mark, with many series getting over 40 episodes a season when they would struggle to even make half of them related to the main stories.

Filler is often misused to mean "any episode not in the original work", even if it's genuine AdaptationExpansion or is an already episodic series to begin with. In some circles, the term gets thrown around so much it seems to more or less mean "the parts I didn't like".

In most casts, the defining aspect of filler is the total ''lack'' of series momentum. Filler can be safely ignored without any loss of important information. However, there is also a style of filler called the "single upgrade filler". Basically, it uses a filler episode to introduce a new power, machine, costume, minor character, etc. without having to work it into the greater narrative. In these cases, the episode can be ignored outside of "something got an upgrade".

For filler in WebComics, see FillerStrip.

Specific Filler tropes include:
* [[RecapEpisode Clips from earlier on in the show]].
* [[GonnaFlyNowMontage Clips of contestants training]].
* [[WackyWaysideTribe Unimportant side-plots.]]

Compare {{Sidequest}}, LevelGrinding and {{Backtracking}} which sometimes turn into the video game equivalent.

Compare BreatherEpisode. When the news media is forced to resort to this, it's SillySeason. Or Sweeps. You decide.

!!Examples

[[folder:Anime & Manga]]
* ''{{Dragonball}}'''s filler ends up being contradicted by canon events in several places, such as an early one where Master Roshi explains the Dragon Balls to Lunch, giving a completely bogus origin story in the process, another where they go visit Android 8's creator an in attempt to have the self-destruct mechanism within him removed, only for it to be revealed in ''Z'' that the previously unseen Dr. Gero was the one who built Android 8. And in ''Z'', there's an episode where Gohan's tail grows back, and so he can transform, Goku's old space pod happens to be nearby and happens to project an image of the full moon onto the night sky, forcing Piccolo to completely destroy it, and then it's revealed that Dr. Brief used Goku's spaceship to create another space pod to be used to go to Namek. Oops.
* ''{{Naruto}}'''s filler famously went for ''over a year'' (80 weeks to be precise) after it OvertookTheManga, and by the end it was being described by fans as a form of torture. The producers of sequel ''Shippuuden'' seem to be taking careful steps not to have that many at once again: even though the manga is three or four entire arcs ahead of the anime, they've cautiously gone back to filler after the second arc, and again after the third one, which precedes two arcs with no opportunities for filler.
** Also notable about the ''Shippuuden'' fillers is that they they are a great step in quality above most of the filler in the original series. Rather than a long series of MonsterOfTheWeek episodes evenly mixed with random variations of DefeatMeansFriendship, the Ninja Guardians arc actually details a full-on storyline with an interesting backstory. True, this troper thinks they could have been a bit braver and [[spoiler: made Sora an ''actual'' jinchuuriki instead of... whatever the hell he was supposed to be. There were plenty of off-screen candidates to make that happen]]. But at least they gave Asuma a story to call his very own; which is a good thing, too, since he probably [[KilledOffForReal isn't gonna get another chance]].

*** The current arc seems to be giving one last chance for screentime to many of the characters. Out of the recurring characters featured in the arc, [[spoiler:3]] will be dead, [[spoiler:2]] will undergo a major shift in personality, [[spoiler:1]] suffers a significant loss in power, and [[spoiler:1]] will, hell, just read.
* ''{{Bleach}}'' seems to avoid the "quality of fillers" complaint; the general complaint on the Bount filler arc has usually been "the filler ''exists''". When asked to elaborate, a fan will usually say "it's not that the filler arc was ''bad'', it's just that the original story is ''better''." The current filler arc, meanwhile, started pretty randomly in the ''middle'' of an established story arc. "Orihime was kidnapped by [[spoiler:Aizen's]] group, but let's take a break and look at something else." It addresses issues that will eventually need to be looked at (i.e. [[spoiler:the lack of captains for squads three, five, and nine]]) but it's just so ''random''.
** They even [[LampshadeHanging acknowledged]] the worthlessness of the filler arc in TheStinger of its final episode. Ichigo trots back to [[spoiler:Hueco Mundo]] like nothing happened (and [[DisContinuity nothing]] [[ResetButton did]]), and Orihime ''shows him the point in the manga where they left off'' when he arrives.
*** The amusing part was how before and after the latest filler arc started, all characters but Ichigo [[AnimatedActors treated it like they were all actors for a show]]. Ichigo was quite confused...
** During the Soul Society Arc, there was a stretch in the middle of a tense part of the storyline that they had a WholeEpisodeFlashback for another character, followed by a DayInTheLimelight episode for characters still on Earth, and then ''another'' WholeEpisodeFlashback episode directly afterwards. Although there were plot in the flashbacks, the actual story didn't move forward more than a few minutes over the course of ''three episodes''. If you're watching to see what's going to happen it can get rather frustrating.
** Even if the story quality is better than average for filler, the Bount Arc still creates continuity problems: There's no reason why Rukia's powers don't return immediately after the Soul Society arc (like they do in the manga) and, in the anime, Hinamori takes an improbable amount of time to recover from her injuries from Aizen (she ''is'' a Lieutenant). There's the oddness with Ishida's powers too. Not to mention it's a major plot point in the Arrancar arc that Orihime didn't do much in the Soul Society Arc. In order for this to still work in the anime she had to be useless in the Bount Arc too.
** The latest set of filler material, around episode 213, indicates that the writers have given up on trying to do anything remotely dramatic, veering into the realm of self-parody. It's also one of the best filler episodes in a long time. Certainly better than the eternal tag filler imported from the manga.
** Filler during the ''Winter War'' Arc is somewhat different. As with many other examples on here, in order to avert too much filler, the writers had taken to putting in as much padding as possible, by using longer openings and recapping the last week's episode and overall plot, which combined take about 10 minutes. For the remaining 12 or so, the action is expanded to fill time until the credits. The sad thing is, the pacing in the ''manga'' chapters is so slow that this isn't enough. There have already been 2 filler arcs during (Shusuke Amagai and Zanpakuto arcs), as well as a half a season of filler, including a BeachEpisode (it is [[FanNickname Titty Kubo]], afterall). But with all this, the anime might still be in danger of [[OvertookTheManga overtaking]] if it moved at the same pace as the earlier episodes.
* To show where Filler can go dangerously wrong, ''RurouniKenshin'' [[TheResolutionWillNotBeTelevised was actually cancelled]] due to the extremely low quality of its FillerArc, and given a movie with a GeckoEnding.
* By contrast, short AnimeFirst series like ''CowboyBebop'', ''SamuraiChamploo'' and ''DarkerThanBlack'', were highly episodic, and, being limited to 26 episodes from the start, had said "filler" as part of its overall story.
* Going against the grain, ''NadiaAndTheSecretOfBlueWater'', despite being only 39 episodes, wound up having a filler arc added in the middle of production. These were the dreaded "island/Africa episodes" (episodes 23-34) in which the entire quality of the production, from the [[OffModel animation]] to the storyline, sank like a stone. They were commissioned only because the ratings were very high and imposed on the production team [[ExecutiveMeddling against their will]]. Hideaki Anno actually had nothing to do with their production because he was so taxed with just fulfilling his original duties and in later interviews expressed that of the episodes, he would only keep ''parts'' of two of them at most because they were so unimportant to the story.
* Any "Chii and [insert name here] Talk" episode in ''{{Chobits}}''. They were considered so pointless and unnecessary to the plot that they were completely excised from the first North American DVD release, and only released as a ''bonus disc'' after fans complained.
* ''SaintSeiya'' managed to have, as a result of OvertookTheManga, an entire filler arc (the Asgard arc) that was as good as (if not ''better than'') the other arcs.
* ''HayateNoGotoku'''s first season of 52 episodes contained almost as much anime-original filler as manga-based episodes. Given the nature of the show, many fans who hadn't read the manga (this troper included) often couldn't tell which was which.
** Fortunately, the second season focuses more on the manga plot... sadly, to the point of [[CompressedAdaptation skipping manga episodes and scenes that aren't vital to the plot]]. Seems this series can't have a middle ground.
* Ditto ''{{Gintama}}''. However, the very first episode of the anime ''was'' completely filler, and managed to initially put this troper off when she couldn't understand what the hell was going on.
* The ''[=~Pokémon~=]'' anime only starts a new game-based arc on the day the games in question are released, in Japan at least. This has led to both filler episodes and filler arcs. While the Orange Islands filler arc was considered to be well executed by the fandom, the Johto arc is considered terrible due to the many bad filler episodes and poor pacing since it had no filler to fall back on before the next region. The Hoenn arc however was considered an improvement, as May's quest was given same the importance as Ash's and thus there were able to get two storylines worth of episodes and need less filler. The Battle Frontier arc was a mixed bag, due to uneven placement of the filler episodes. Time will tell however whether the Sinnoh arc will be done well, as it looks to be even longer then the Johto arc.
** Early on, many filler episodes were simply the result of a carnival being in the town ''juuuust'' as Ash and co. arrived. Other times, it was due to them getting lost because no-one could [[CantReadTheMap read the map properly.]]
* The ''[[TheSlayers Slayers TRY]]'' season, while still helmed by the original creators, has a storyline not adapted from the original LightNovels. It dealt with a threat of Lina's world being destroyed by a Mazoku Lord from another universe, when said Dark Lord only had a small appearance in the original novels as the creator of Gourry's [[LaserBlade Sword of Light]]. The new season ''Slayers REVOLUTION'' returns to adapting events and characters from the novels that have not yet appeared.
** This troper actually ''prefers'' the filler episodes of the various seasons of ''{{Slayers}}''.
** ''{{Slayers}}'' does have at least three or four per season, and they are usually the funniest parts.
* The third season of the ''IkkiTousen'' anime, Great Guardians, has no basis in the original manga and has little bearing on the overall plot. The slightly slower pace and bigger emphasis on character interaction still make it a fairly enjoyable watch though.
* A large part of ''[[MegaManNTWarrior Rockman.EXE]]'' Stream was like this. In fact, this troper remembers being surprised when the series put forth actual plot.
** Megaman Starforce was even worse. It had a great plot for the first half, a lot of promise. Then the creators forgot there was a plot for almost the entire second half of the series. So we got a bunch of random episodes about the [=FMs=] goofing around on earth until the last few episodes when the creators finally remembered that there was a plot. The series was hastily ended with a lot of loose threads and a bunch of stuff that made no sense unless you had played the Starforce video game, and even then the plots between the two mediums were so different by that point that is was more of a fill in the blanks and hope you're right thing.
* ''MagicKnightRayearth'' anime in the first season has a lot of filler episodes. This, however, proves to be very important when it comes to CharacterDevelopment. It also borrows several elements used in the manga too.
* The OddlyNamedSequel of ''ShugoChara'', ''ShugoChara Doki'', is yet only consisting of those. After the original series started getting DAMN close to OvertookTheManga, they started Doki with a pretty pointless filler arc about a french girl, who turns Shugo eggs into Question-mark-eggs. It finally finished after 39 episodes.
**To be fair, the plot does continue while this arc is going on, albeit in an extremely dragged out manner. The big problem with Doki is that Lulu was only created to produce MonsterOfTheWeek filler, so she sticks around for far too long and has a nasty habit of forgetting her CharacterDevelopment when the episode only needs her as a plot device.
* Altough not as much as ''Naruto'', ''[[YuGiOh Yu-Gi-Oh!]]'' has a LOT of filler (about 80 episodes out of 224). Noah's Filler Arc commited the sin of showing up in the middle of a bigger arc (and leaving some plot holes, such as -- if Evil Marik had all this time alone in the Battle Ship, why didn't he search and kill Rishid?). The other two Filler Arcs though, the Oreichalcos one and the KC Grand Prix one, are very disposable and are sillier than the show usually is. Besides, the Oreichalcos arc denied all of Mai's CharacterDevelopment, and that's no good.
* ''SoulEater'' had a few hilarious fillers involving the character Excalibur, who's pretty much a filler-character, although he does come in on the last arc.
* ''SailorMoon'' has a fan guide called "[[http://eclectic-world.com/myaddictions/animania/archives/213-Sailor-Moon-Essential-Episodes.html Sailor Moon Essential Episodes]]" that roughly pinpoints 53 episodes as completely irrelevant filler, with an additional 51 being single plot point/power upgrade curiosities (along with five vital episodes of the Doom Tree arc still considered filler). The show only had 200 episodes total. That's pretty impressive in and of itself, but the show went even further and changed many plot points from the manga in order to extend the series further. The Seven Great Yoma and the final season BigBad attacking civilians with full knowledge of her real targets were constructs designed just for filler.
* ''DennouCoil'' is mainly the story of Isako and her connection to the weird phenomena in the virtual world. This makes the episodes in which she doesn't even appear feel rather pointless.
* While the first anime adaptation of ''FullMetalAlchemist'' had some filler, the ReMake is ([[TemptingFate so far at least]]), an aversion: characters and events introduced in the original's filler episodes (like the introduction of Barry The Chopper and the Elrics removing a corrupt official of a mining town from power) are only quickly referenced, letting the main StoryArc progress in every episode.
** In fact some are fearing it might be headed into the ''[[CosmicDeadline opposite]]'' [[CompressedAdaptation direction]], though this may simply apply to the episodes covering stories already adapted into the first anime.
** The first anime also averted filler for the most part (with the exception of two episodes at the beginning) due to the writers [[PragmaticAdaptation going in a completely different direction]] with the plot.
* ''ZatchBell'' actually had quite little filler, especially if compared to [[SailorMoon other]] [[DragonBall Toei procuctions]]. But then the anime almost OvertookTheManga, and the producers decided to make a completely anime-only arc, the Shion Arc. While this troper never read about Makoto Raiku's opinion on it, general consensus is that it's a ''very'' good arc, with interesting characters and a nice TearJerker.
*Compared to most shows of its length (ten years and counting!) {{One Piece}} has had relatively few filler arcs, due in part to how jam-packed with details Eichiro Oda's stories tend to be (making it easy for writers to do {{adaptation expansion}}.) The filler arcs which are present are a mixed bag; fans generally hate the [[{{thescrappy}} Apis]] arc, but many consider the G8 arc to be good enough to stand with the best of the canonical material. The recent Ice Hunter arc got high marks as well, perhaps because it was outlined by Oda himself.
** Some of the filler arcs are based on storylines which Oda planned for the manga but which were later cut to keep the plot moving. The upcoming 10th movie also began life this way.
* RanmaOneHalf is an example of the manga and the anime both having filler. The anime has a somewhat larger amount, as it did adapt a number of manga filler stories (for example, the Harumaki story, where a random old guy with astral projection forces Ranma's girl form to go on a date with him) while still having its own unique filler, but it's undeniably present in the original medium. For example, one manga story has the Tendo Dojo receiving magical "oni-killing" plant that uses its BulletSeed attack on anyone with an angry face and promptly terrorizes the household until [[YamatoNadeshiko Kasumi Tendo]] just throws it into the garbage. As in all cases, the quality of various filler stories ranges widely and a lot of YourMileageMayVary is involved. For example, one technically filler episode manages to take [[CanonForeigner Sasuke Sarugakure]] and not only make him interesting, but border-line tragic.

[[folder:Comics]]
* For the first period of time that Magneto was PutOnABus in the ''{{X-Men}}'' comics, the X-Men faced off against such [[FillerVillain "notable foes"]] as the Locust, the Porcupine, and the Scarecrow (no, not [[{{Batman}} that Scarecrow]] -- this one has about 12 trained attack crows). And they added a new member to the team. For two whole issues.
* Filler issues in comic books often exist because of plans changing at the last minute. ''ComicBook/TeenTitans'' had a crossover with ''Outsiders'' with another crossover planned soon after. DC decided to just make the second crossover a separate miniseries, resulting in a two-issue filler arc in each book.

* The ''majority'' of chapters in the InheritanceTrilogy can be described as walking around and talking while no plot progresses. Although it's often times to difficult to identify what the plot is.
**Difficult to identify the plot? Your right they only say it about 50 times a book. Also name the chapters that do that because I only count about one or two.
[[/folder]]

[[folder:Live Action TV]]
* Somewhat justified in certain live action SF and fantasy series like ''DoctorWho'' and ''{{Buffy the Vampire Slayer}}'', because the [[HalfArcSeason series or season arc would generally unfold slowly over the course of many episodes]]. This is true even of long-running series like ''Stargate'', in which each season has its own StoryArc, and most episodes at least address the main arc at some point -- and even then some of the episodes that have very little effect on the arc have proven to be popular with fans due to being humorous {{Breather Episode}}s, such as the GroundhogDayLoop episode "Window of Opportunity", or the self-parodying episodes "Wormhole X-Treme!" or "200" (all from ''Stargate SG-1''), or the Halloween episodes of ''Buffy''.
* Related example: ''SuperSentai'' and ''PowerRangers'' mostly follow the [[HalfArcSeason "half arc, half filler"]] formula, but each ''Sentai'' series has to run for a whole year's 48-52 episodes, whereas ''Power Rangers'' are usually much shorter. Some fans feel that the short seasons are sometimes an improvement, since 32-episode PR season is much more story intense and less filler-ridden than a 50-episode ''Sentai''.
** Others argue that the PR seasons are ''too'' story intensive, as the writers try to condense as much of the original material- both story and filler- as possible into a smaller number of episodes. At best it spoils the pace of the story (e.g. fitting a two-episode storyline into one twenty-two minute episodes) and at worst it results in something barely watchable.
* ''Less'' justifiable in the original series of ''DoctorWho'', however. Serials running for five to seven episodes or more usually have so much padding, contrivances and irrelevant storylines they can get hard to watch. This was reduced in later series (starting around the Third Doctor), with a more manageable four episodes per serial and rarer six-part episodes. Even in the Sixth Doctor season 22, where the runtime was temporarily switched to 1 hour instead of the usual half, the serials go over the two parts only once.
** In particular, the First Doctor serial ''The Dalek's Master Plan'', a massive 12-parter (plus a prologue episode broadcast weeks earlier and notable for not featuring any of the main cast), had a ChristmasEpisode intentionally meant as filler.
* A few seasons into ''[[TheXFiles The X Files]]'', the show settled into a mixture of [[MythArc "mythology"]] episodes and [[MonsterOfTheWeek "Monster of the Week"]] episodes. If you were watching for the myth arc, the Monster of the Week episodes were filler. Towards the end, though, this troper preferred them to the impenetrable, contradictory mythology episodes....
* ''ThePrisoner'' was originally intended to be a seven episode miniseries. The network wanted more, and so ten standalone episodes were created and intermixed with the main StoryArc. Less noticeable than in other series with a high filler percentage, as most of the filler episodes are still good.
* American game shows are terrible about this, especially recent ones on FOX. These shows like to stretch out the time between a contestant's answering the question and the reveal of the actual answer. One example in particular, ''Don't Forget the Lyrics'' (which could be described as karaoke, but with more Wayne Brady) will sometimes pad this period out for as much as ''one or two minutes'' at a time (not including the commercial break in-between) by revealing only one correct word at a time and allowing 10-20 second pauses between reveals. Most execs would probably argue that this is to "heighten the suspense" but the viewing audience pretty quickly realizes that each of these hour-long shows could be half an hour if not for filler.
** Of course, cutting the {{Filler}} for a half-hour time slot would be CompletelyMissingThePoint which is to fill airtime as cheaply as possible...
** ''AmericanIdol'' has so much filler that it's a RunningGag on its page.
[[/folder]]

[[folder:Video Games]]
* FinalFantasyXII has about 30 hours worth of story and 200 hours of sidequests that consist of plotless monster hunting.
* ''MetalGearSolid: Portable Ops''. All the more insulting because it had been marketed as 'the missing link in the tragedy of Big Boss', promising to explain how Big Boss rose to power and went off the deep end, but actually did little more than retcon one much-loved character's backstory, bring back a dead character for no real reason (although, to be fair, this was lampshaded by the character using the pseudonym 'Ghost'), and explain how Big Boss came up with Outer Heaven's... ''name''. Sigh.
* ''TalesOfSymphonia'' had the infamous and distracting [[SoupCans hunt for the Ymir Fruit]] in Ymir Forest, a fruit that was said to be able to cure every disease. The fruit was needed to heal an elf woman which was never seen in game, and which had no impact on the plot. The player had to solve the puzzle regardless, since the sick woman's child blocked the way to the protagonist's destination. (strangely, the protagonists ignored the fact that they were on a quest to cure a disease of one of their party members at that time and could just [[FridgeLogic use the fruit to heal her]]. They prefered to [[PlotInducedStupidity clear three annoying dungeons]] instead).
[[/folder]]

[[folder:Western Animation]]
* ''{{Avatar the Last Airbender}}'' had a few episodes per season, which includes both "The Runaway" (one of the more popular episodes of the series) and "The Great Divide" (generally the least liked episode of the series). [[LampshadeHanging Lampshaded]] in a [[RecapEpisode recap]] [[ShowWithinAShow parody]] towards the end of season three:
-->'''Aang:''' Look, it's the Great Divide! The biggest canyon in the Earth Kingdom!\\
'''Sokka:''' Ehh... [[DiscontinuityNod Let's keep flying.]]
** A better lampshading is the actual introduction to the recap episode:
--->'''Sokka:''' Come on, a day at the theater! This is the kind of wacky time-wasting nonsense I've been missing.
* Most of Season 4 and parts of Season 3 of ''CodeLyoko''. Ironically, Season 1 was a MonsterOfTheWeek kind of show, but it started out that way, and thus, the idea of filler wasn't a consideration until after such time as the series [[GrowingTheBeard grew a beard]], so to speak, and shifted to a StoryArc format for Season 2 and the Prequel episodes. So, it's debatable if the so-called filler was really just a return to form.
** Also, due to Season 1's MonsterOfTheWeek format, you could actually watch most of the episodes in ''any order'', with the exception of the season finale, as the last episode of that season starts off from where the previous one left off, making it a two-parter.
