Like a StoryArc, but ''longer'' -- spanning the series.

The term originated with ''TheXFiles'', though ''[[BabylonFive Babylon 5]]'' is probably a better example of an effective MythArc. Comparing ''TheXFiles'' to ''[[BabylonFive Babylon 5]]'' provides an object lesson in the value of knowing where you're headed when you set up a large-scale arc: both series had slow-building (often season-spanning) stories, but ''[[BabylonFive Babylon 5]]'' would eventually resolve its stories while ''TheXFiles'' overarching plot just got strung along further and further, until -- in what's now called TheChrisCarterEffect -- its viewers lost confidence that the plots would ever be resolved.

In some shows -- such as the aforementioned series -- the trend is to alternate between MythArc stories and MonsterOfTheWeek episodes, making it easier for new viewers to get into the show and ensuring some short-term gratification while keeping the viewer's interest over the long run. However, [[SeasonFluidity heavily arc-based shows]] like ''Series/{{Heroes}}'' show that the American public is willing to invest their time over longer periods too.

{{Anime}} series very often have arcs running the entirety of their series, which can span hundreds of episodes, with examples such as such as ''{{Robotech}}'', ''NeonGenesisEvangelion'', ''MartianSuccessorNadesico'', various ''{{Gundam}}'' shows, ''{{Noir}}'' (which had a Myth Arc from the very first episode), and others. The predominance of such arc-based plotting in anime (many of which were introduced to foreign audiences in the mid 90s), as opposed to the generally episodic nature of American TV series of the 80s and 90s, is part of what led to the massive rise in anime's popularity with the nerd-core at that time, and many suspect that the development of multiple Myth Arc-based shows on American television in the [=2000s=] was a reaction to that.

Can lead to a ContinuityLockOut.

[[folder: Anime and Manga ]]

* LegendOfTheGalacticHeroes
* ErgoProxy
* LastExile
* {{Trigun}}
* ''GurrenLagann'' is about humanity's struggle for freedom. [[TimeSkip And then]], humanity's ''other'', [[BiggerIsBetter bigger]], more {{Badass}} struggle for freedom.
* ''NeonGenesisEvangelion'' has the war on the Angels, which is later revealed to be a small part of [[spoiler: SEELE's ''Human {{Instrumentality}} Project.'']]
* The ''{{Macross}}'' franchise, in addition to having individual arcs in its shows, possesses several myth arcs that run throughout the ''franchise'', including learning more about the Protoculture and the origins of mankind and the Zentraedi, and finding worlds to replace the seriously damaged Earth.
** While generally considered a horrible {{Macekre}}, the ''{{Robotech}}'' franchise born from ''{{Macross}}'' possesses a somewhat similar but altered MythArc involving the Masters and their manipulation of multiple races throughout the galaxy, which culminates in the Earth becoming a shooting gallery for ''several'' interstellar conflicts.
* The modern remake of ''BubblegumCrisis'', subtitled ''Tokyo: 2040'' significantly differed from its predecessor in having a significantly developed myth arc, as opposed to the prior's tendency to single episodes and two-parters at most.
* ''{{Naruto}}'' often has many recaps and episodes that show who all the charaters are, what's been going on, etc. -- not only to fill in new viewers, but to help Masashi Kishimoto [[OvertookTheManga write more]], as well.
* ''OnePiece'' has changed focus from the search for the titular treasure to an myth arc relating to the World Government, a corrupt worldwide organization that came to power during a lost part of history, and their relationship to the most powerful pirates in the world.
* ''CowboyBebop'', while mostly episodic, has two basic plots running through the whole series: [[spoiler:Faye's search for her past and identity, but most importantly, the full story of Spike's life as a mobster and his lost love, Julia]].
** And from the same creator, ''SamuraiChamploo'' has the search for the Sunflower Samurai.
* ''SuzumiyaHaruhi'' alternates between enthralling plots and (usually) comedic side stories. (The novels are either a full story divided into chapters, or full off short stories)
* ''{{Shaman King}}'' does this when, sometime between the end of Season 1 and the start of Season 3, the focus of the series leaves the Shaman Fight entirely and delves off into exploring Hao's involvement in [[spoiler: his third consecutive Shaman Fight, at each of which he attempted to steal the Great Spirit]], as well as Hao being [[spoiler: Yoh's ''EvilTwin'']]. In fact, the series ends before the Shaman King is even decided.
** It didn't exactly end, it just went on an extremely long and sudden hiatus. The final issues are being published ''now''.
* ''{{Code Geass}}'' contains an on-and-off form of Myth Arc revolving around the true nature of the Geass power. This arc begins arguably in the first episode, when Lelouch receives Geass, but the implications of the power are almost always overshadowed by the Britannian / Eleven conflict. The Geass Arc comes into its own later when [[spoiler:Mao appears. Mao cannot turn off his Geass, foreshadowing when Lelouch's Geass also becomes uncontrollable. (Mao also might introduce the Chinese Federation, and what life is like there if reading people's minds there made him nuts.)]] The Geass Arc effectively ends in Episode 21 of R2, when [[spoiler: Lelouch brings his Geass it to its final permanent binocular form, in order to use Geass on the World of C, ultimately destroying the Thought Elevator and killing both Charles and Marianne. Later on, when Lelouch, Suzaku, and C.C. return from the World of C, emerging in the Schneizel Arc, when Lelouch finally catches up to all the second-guessing and criticism thrown at him behind his back while he was busy during the Geass arc.]]
** The main story itself is filler free and each episode is but a chapter in Lelouch's story.
* DeathNote has one.
*''{{Slayers}}'' is pretty good at alternating between MythArc and filler episodes. While each season will have one story arc spanning it, the three story arcs are intricately connected and form one very long plot.
* ''MahouSenseiNegima'' has Negi's search for his DisappearedDad. It doesn't really become central until around volume 6, which is naturally [[GeckoEnding where the anime adaption cut off.]]
* VinlandSaga has Thorfinn's dreams of Vinland and the phrase 'somewhere not here'.
* Despite the first chapters of ''FullmetalAlchemist'' looking like your usual shonen AdventureTowns, the whole manga is one long and steady MythArc. The author has actually said the ending for the story was the first thing she came up with, and then worked backwards from there.
* All of the recurring story lines in ''DetectiveConan'' fall under this.
* ''{{Monster}}''
* TwentiethCenturyBoys
* Pretty much the entire first season of EurekaSeven is just foreshadowing for the second half of the series and getting to know the characters.

[[folder: Literature ]]

* TheDarkTower is, of course, about Roland's journey to The Dark Tower.
* ''{{Animorphs}}'' has one with the Yeerks, namely the overarching conflict across the galaxy. It was basically guaranteed that any book narrated by Ax would discuss this slight bit, any book narrated by Marco would have the myth-arc regarding [[spoiler:his mother, Visser One]], and stuff narrated by Tobias would deal with the Hork-Bajir, and the Anti-Morphing Ray arc. The whole series had the myth-arc of the war between Crayak and Ellimist, generally covered in Rachel's narrations.
* ''HarryPotter''.
* Umberto Eco's novels (''TheNameOfTheRose'', ''FoucaultsPendulum'', ''TheIslandOfTheDayBefore'', ''{{Baudolino}}'', and ''TheMysteriousFlameOfQueenLoana'') supposedly form a MythArc, but rather infuriatingly, he ''never says what it is'', and the connections are [[JigsawPuzzlePlot too subtle]] for anybody else to even ''begin'' to guess.
* Steven Eriksons ''MalazanBookoftheFallen'' myth arc [[spoiler:about the Crippled God]] covers several hundred thousand years (mostly in backstory) including [[spoiler:dragons, primitive hominids, many many gods and demigods, multiple world-spanning disasters and what ever the heck happened to Mother Dark]]. The histories of [[spoiler:Dessimbelackis' First, the Malazan and Letherii)]] empires are also mysteries that carry the plot. Dang archeologists.
* LordOfTheRings, as well as many other popular fantasy series'.
* {{Hyperion}}
* HisDarkMaterials

[[/folder]]

[[folder: Comics ]]

* ''{{Preacher}}'': Jesse, Tulip, and Cassidy's ongoing search for {{God}}.
* ''TheSandman'' is a clever example of a MythArc in disguise. While the occasional volume may have some development on what would ''seem'' to be an ongoing story (''Season Of Mists'' and ''Brief Lives'') It is not until ''The Kindly Ones'' when we learn that nearly all aspects of the series were parts of [[spoiler:Dream's ongoing [[XanatosRoulette plan]] to evolve himself into a more sympathetic being.]]
* The entirety of ''{{Watchmen}}'' is about the mystery behind The Comedian's murder, and more importantly the motivation behind it.

[[/folder]]

[[folder: Music ]]

* FrankZappa did this with his ''music''; he had a massive stockpile of cultural references, injokes, and musical riffs which he repeatedly drew from over his thirty-year career.
* Coheed and Cambria's music is one enormous myth arc.
** Complete with a tie-in comic book. Written by Claudio Sanchez himself!
* Craig Finn's bands, Lifter Puller and The Hold Steady both contain myth-arcs of a sort.

[[/folder]]

[[folder: Television ]]

* ''{{Lost}}'' has a MythArc built in, though it is a bone of contention as to whether the authors actually know where they're headed or not (see ''TwinPeaks'').
** The [[WordOfGod official line from the creators]] is that they know how they want to end the series, and how to direct the plotlines to get there.
**It has now been confirmed that season 6 will be the last one.
* Unsurprisingly, a number of shows that [[FollowTheLeader tried to cash in on the success of]] ''{{Lost}}'' had them, too: ''{{Invasion}}'', ''{{Threshold}}'', ''{{Surface}}'' -- well, we assume they did; they were cancelled before the arcs could develop.
* More successful were ''{{The 4400}}'' and ''Series/{{Heroes}}'', although the former actually predated ''{{Lost}}'' by a good few months.
* ''TwinPeaks'' looked like it had a MythArc, but David Lynch later admitted he had been making it all up as he went along.
* Both versions of ''BattlestarGalactica'' were arc-based, though elements thereof were made up on the fly; in the 2000s version, for example, the one-shot character Sam Anders was reintroduced into the arc 15 episodes after his first appearance, and became a recurring character in Season 3, because actress Katee Sackhoff (Starbuck) wanted her character to have a love interest. By season 4 it is fair to say that he has suddenly become absolutely vital to the ongoing (and soon to be ending) arc.
** Before Sam Anders, another one-shot character who ended up being relatively fundamental to an ongoing plot point of ''Galactica'' is Karl "Helo" Agathon. Originally he was supposed to die abandoned in Caprica during the miniseries. The Powers that Be liked him enough to bring him back to eventually be [[spoiler: the father of the shape of things to come, Hera,]] and occasionally the second in command of Galactica herself. [[spoiler: Also, one of the few who managed to get a truly happy ending ... well, if you consider living like a luddite on the prehistoric savanas of Africa a fraking happy ending.]]
* While ''{{Supernatural}}'' is also a {{Monster of the Week}} show, the main ongoing plot-driven arc is Sam's destiny and the demon invasion. You could also say that Dean's battle with possibly the worst self-esteem in the history of television characters is also a more emotionally-driven mini-arc.
** By seasons 3 and 4, Sam's destiny has become just a small part of the series' main (read: apocalyptic) MythArc, while Dean's self-esteem issues have become most crucial.
* ''DoctorWho'', particularly the new series (although the classic series had series-wide plots like the "Key to Time" arc. Additionally, an element of the Third Doctor's final season was his continually obstructed attempts to reach the planet Metebelis III. [[spoiler:When he finally did, things didn't go well]].
** [[spoiler:Bad Wolf in series one (with a coda in series four), Torchwood in two, Mr. Saxon in three, and a combination of threads from every episode in series four leading in to the finale ("The bees are disappearing")]].
** The entire run of classic and new series has a few common threads running through; most notably, the premise of "Doctor who?" has varying surges of interest in different series; the new series has picked up on the mystery behind the Doctor's name again, with [[spoiler:"Forest of the Dead" confirming that he actually ''has'' a real name]]. Whether or not these questions can be classed as arcs probably hinges upon whether they were ever ''intended'' to be answered.
* ''{{Fringe}}'' appears to have a developing myth arc at only six episodes in. Unlike J. J. Abrams' previous shows (''{{Alias}}'' and ''{{Lost}}''), the word is that the myth arc has been planned from the beginning. The writers have been careful so far to make each episode seem self-contained, though.
* ''{{CSI}}'' did one fairly recently with the "Miniature Killer", so called because they would leave a perfect scale model of the crime scene there, and which served as the set up at the end to put one of the regulars [[PutOnABus on a bus]].
* Originally intended to be an episodic supernatural-mystery-of-the-week series, ''{{Angel}}'' began developing a myth arc of its own with its first season finale, involving Angel and friends being pivotal players in an upcoming apocalypse. {{Your mileage may vary}} as to how way it was pulled off.
*''TheSarahConnorChronicles'' has a running MythArc regarding the characters preventing Skynet's creation and Judgment Day, though it also focuses on numerous subplots and a lot of personal character development.
* ''PowerRangers'' is [[WildMassGuessing suspected]] to have a bit of a thin one -- introduce villain's empire in season 4, give villain motive in season 6 by destroying said empire, show long-term aftermath of villain's attack in season 9, introduce villain in season 10, show how planet will become is vulnerable in season 13, then show the actual fight against the villain and the attack itself in season 17.
* ''EarthFinalConflict'' was both loved and praised by its fans for its complicated, multidimensional and just way too convoluted arc. The writers were smart enough to make all things vague and open to personal interpretation to avoid an inevitable SeriesContinuityError and mostly let the viewer himself discern right from wrong.
* ''{{Monk}}'': Finding out who murdered Trudy Monk.
* ''[[BabylonFive Babylon 5]]'', as mentioned in the article itself, is one of the archetypical Myth Arcs, and often credited/blamed for the proliferation of Myth Arcs in science fiction shows since.
* The quirky PoliceProcedural ''{{Life}}'' was an example of the mixture idea: while each episode involved solving an individual MysteryOfTheWeek, most episodes would also involve the main character's quest discover who arranged for him to be wrongfully convicted of murder. This story was left largely hanging by the series' abrupt cancelation. While, by the second season's finale, he had learned ''why'' he was framed, he had not learned ''who''. (And since the "why" was the second one claimed in as many seasons, that, too, could have been merely a RedHerring.)

[[folder: Video Games ]]

*The ''MightAndMagic'' games have individual plots that are quite simple and a much more complex plot that spans the entire series as well alternating with the ''HeroesOfMightAndMagic'' spinoff series. Playing the entire franchise in the fiction's chronological order can be very interesting as all the pieces of the puzzle click together.
* ''MetalGearSolid''. Good ''god'' Metal Gear Solid... though there's a school of thought that Kojima was just making it up and {{retcon}}ning as he went along. Reportedly, he wanted to end the series with ''MetalGearSolid'', but got pressured into continuing. Taking four whole games on 3 different consoles to setup and resolve the [[spoiler:Patriots]] arc might be his way of getting revenge.

[[folder: Web Original ]]

* ''{{KateModern}}'', though whether they manage to resolve it before the show ends [[TheChrisCarterEffect remains to be seen]].

[[/folder]]

[[folder: Webcomics ]]

* AbstractGender: Who experimented on Ryan and Brian and why? Unfortunately, the series ended before this question was answered.
* ''GirlGenius,'' starting with the [[http://www.girlgeniusonline.com/comic.php?date=20021111 fourth strip]] and continuing until today -- and likely quite some time into the future as well.
** ''Girl Genius'' ''started'' as a comic book series, so that "fourth strip" is ''actually'' the fourth ''page'' of the first ''issue''.

* Tons in ''ElGoonishShive'', the early strips are packed with many [[ChekhovsGun clues]] for later arcs. In a more specific sense, Lord Tedd and Tedd's backstory.
** Somewhat subverted in that the creator admits that he has thrown out much of the earlier foreshadowing as irrelevant to the ever-changing 'current' direction of the strip.

[[folder: Western Animation ]]

* The point of ''DannyPhantom'' -- according to the fans, anyway. Although it's [[ScrewedByTheNetwork hard to tell]] [[DisContinuity after season 2]].
* ''AvatarTheLastAirbender.'' Given its similarity to {{Anime}}, it's not surprising.
* The French cartoon ''Les Mondes Engloutis'' ("The Engulfed Worlds" in French), translated as ''Spartacus and the Sun Beneath the Sea'' in English, centered around the protagonists' search for a way to keep the titular Sun from dying and destroying the underground civilization of Arcadia. The show lasted only two seasons, and was ended when the heroes eventually discovered the truth behind the Sun and what was needed to save the people of Arcadia.
* ''{{Futurama}}'' had one literally set up in a shadow of the very first episode that we didn't know about until two seasons afterwards.
