The real reason is that those episodes of GT were lighthearted comedy in the vein of the original Dragon Ball, which wasn't nearly as popular in the West. Cartoon Network chose to skip these in favor of the more action-packed, DBZ-style episodes, clearly knowing their audience. Of course, this was also the era when GT had a Theme Tune Rap.
That was Funimation's doing actually, knowing the show's infamous reputation. Wound up doing wonderfully for their sales due to the backward releases. According to FUNimation, despite the series' notorious reputation, DBGT is consistently among their top selling titles, actually rivaling Dragon Ball Z in sales.
In the original run of the edited version of Dragon Ball Z, two episodes were pulled. One was early on; a young Gohan gets lost in a cave during his wilderness training and encounters a grouchy robot, who ends up becoming fond of him and sacrifices his life to save Gohan. The reasons for pulling this episode are unknown. The other occurred on Toonami, after Frieza impales Krillin on his horns; in the first half of the episode, Frieza continually tortures him until he's lost nearly all the blood in his body.
More material was cut out of the edited version of the first two seasons. At that moment, fifteen episodes' worth of material were edited out, including most of the first episode and Tenshinhan's Z-era introduction to name a few. In addition to that, an episode created for the edited broadcast (Episode 10: "Escape From Piccolo") was skipped over in '96 due to objectionable content and only reinstated on the home release and on television in '98 after making the jump from syndication to Cartoon Network.
Mazinger Z: In Spain thirty-two episodes from the first season were broadcast. The first season was fifty-seven-episodes long. They were aired out of order, too.
The DiC dub of Sailor Moon threw out several episodes entirely. These were not seen (legally) in the US until the uncensored, subtitled ADV release. Even that did not include Sailor Moon R episode 67, a Beach Episode with no relation to the rest of the plot or the setting of the show; it has Chibi-Usa befriending a baby dinosaur on an island off the coast of (then) current-day Japan. It was claimed by an ADV representative that Naoko Takeuchi despised that episode (as did the director), and that Toei refused to license it, although the episode showed up in other countries' adaptations. (Later, it was clarified that ADV had obtained its masters from DiC, which lacked the episode.)
Episode 89 was skipped in several countries, but oddly not in the DiC dub. That and the fact that it was a clip show led many fans to think it was made by DiC, even though it was part of the Japanese run.
The Swedish dub skipped episodes with "too much music". Only the first two seasons aired.
The Albanian dub skipped the third and fifth season entirely. Aside from Rini's returning in the third season, and already being a Senshi, there were really no plot holes.
In Poland, three episodes were skipped: 45 and 46 were skipped because Polsat (the station that aired Sailor Moon in Poland) got the package that excluded these episodes, and 133 was skipped to avoid possible offense to Catholics.
In South Korea, many episodes were skipped due to content and cultural reasons, including most of Rei's debut episode. In fact, ANY scene showing Rei's temple, or Rei wearing her shrine priestess uniform were cut, and episodes featuring the shinto shrine frequently within the episode were cut or merged (this was because their dub was trying to remove as many references to Japan as possible, due to the two countries' bitter relationship). Other episodes with a large amount of "inappropriate" content were also cut (including too much kanji, lip-locking, violence, sexuality, and frightening images). In all, only 157 of the 200 episodes aired, leaving forty-three episodes unaired.
The last season has never been shown in the US, due to licensing for Sailor Moon being revoked outside of Japan before Cloverway or Pioneer could get to them. (This will change with VIZ's 2014 acquisition of the series)
The original 4Kids dub of One Piece skipped a number of episodes (read: nearly forty) during its run on Cartoon Network. Part of this was accomplished by cutting slower-paced episodes together, but much of it was due to skipping entire story arcs to introduce "marketable" characters more quickly, leading to some truly gargantuan plot holes. The episodes stopped being "missing" in the US after Toei handed the series to Funimation, who promptly got to work on making an uncut release.
The Hot Springs Episode of Outlaw Star was dropped from the dub on Cartoon Network, since it'd take too long and cost too much money to digitally cover the sheer number of naked breasts and crotch on the female characters and tone down some of the sexually suggestive lines. There does exist an edited version for pre-watershed screening, but due to the adult content of the episode, the edit has a vastly shorter run time. The episode was shown, although with some apparent cuts, on the short-lived CNX Channel in the UK and is available on DVD uncut and uncensored.
The third episode of the new Black Jack anime was left unaired because part of the plot dealt with an earthquake, and a real earthquake struck Japan hours before it was to air, though the episode aired just a couple of years later. An episode of Pokémon also suffered the same fate, and so far only a preview of that survives.
The Black Jack manga has a number of "sealed chapters" that were cut from the collected volumes for being too morbid, too controversial, or just not very good.
Pokémon is notorious for this among the fan community. Most of these are only missing from non-Asian dubs (all sourced from the English dub), but there are a lot of examples:
"Beauty And The Beach" was a Beach Episode, for one, but it really got itself banned for the scene where James cross dresses to enter the swimsuit contest with fake breasts, and then taunts Misty that his boobs are larger while inflating them. A clip from this episode actually appears in flashback form in a later episode, confusing the hell out of viewers for years. A heavily-edited version aired three years later in 2000, but even that one was deemed so sexist it was never shown again. This caused severe dialogue changes in the next episode, which featured a twin (actually cousin) of one of the characters from this episode that in the original vehemently objected to confusion with her twin. Of course...
That next episode was "Tentacool and Tentacruel". It aired just fine then and years afterward, until 9/11. It was taken out of rotation as Too Soon for a scene where a giant Tentacruel smashes up a building, even though the building didn't look anything remotely like either of the Twin Towers, and even though that very scene was (and remained) part of the opening titles. There were other reasons, too, with the character Nastina using military style weapons during the fight scenes. It didn't come back until the Channel Hop to Cartoon Network a few years later.
"Tower of Terror" was banned as Too Soon after 9/11 solely on the basis of the name, and Cartoon Network couldn't pry the rights for it until late 2007, which is an extremely loose definition of "soon" (for context, this was well over a year after the channel-hop). It was the middle part of an important three-episode mini-arc, to boot.
"The Legend Of Dratini" was banned from the beginning because of a metric fuckton of gun play, including two characters getting guns to their heads and one character shooting off about a hundred rounds at Team Rocket from two revolvers to interrupt their motto. Another reason may have been because of Meowth donning a Hitler-esque mustache for one scene. Extra fun when in later episodes, Ash suddenly has 30 Tauros we never saw him catch, because he caught them here. Also could have been trouble since this is where the gang gets to the Safari Zone they had been searching for for a couple of episodes, but luckily the previous episode just happened to feature a nature preserve that just happened to be right next door to the Safari Zone which is also supposed to be a nature preserve. It was pretty easy to edit dialogue to make that episode the Safari Zone and actually make things more logical than they were before. The mere presence of guns was undoubtedly not a factor, though; an earlier episode, featuring the Squirtle Squad, has a scene where a store full of people all point guns at Ash thinking he's there to rob the place, and the aforementioned nature preserve episode also had an Officer Jenny pointing a rifle at Ash and co. thinking they were poachers. In any case, this episode has never been available for legal viewing in the US.
"Electric Soldier Porygon", the infamous episode that gave viewers epileptic seizures. It was only aired once in Japan, where the strobe effect employed caused seizures in some Japanese kids. And then a whole lot more Japanese people got sick when the news reported on it by showing the clip that was giving people seizures! This wasn't the only episode where the effect was employed, but while the previous episodes had the strobe effect removed, this episode was simply pulled. The episode can be found on YouTube, where it can (reputedly) be watched safely due to the lower frame rate. In fact, anime had been like this for years and it wasn't until the Porygon episode that this kind of thing stopped.
The delay caused by Electric Soldier Porygon caused two episodes to be delayed and run as specials (Holiday Hi-Jynxnote which, oddly enough, was also pulled from rotation after a single viewing in America due to racist allegations, although it can still be legally viewed online or as part of home releases and Snow Way Out!), five episodes were rescheduled, and one was canceled altogether (a New Year's Eve episode).
This is the only episode from the Pokémon franchise the producers refuse to export anywhere, even in other Asian countries, because of this incident. However, according to Maddie Blaustein, Meowth's voice at the time, 4Kids had actually dubbed the episode, and even modified the strobe effect by dimming it and slowing down the frame rate. However, the producers demanded the episode be banned regardless, likely due to the controversy that even airing the episode would cause (or at least the fear of). The incident also forced them to go back and dim the flashing effects in earlier episodes.
In South Korea, "Challenge of the Samurai" was banned for obvious reasons, and five other episodes were banned because the Korean Media Watchdogs knew that those episodes would discriminate their culture.
After all this Season 1 madness, things ticked down a lot, but a few more missing episodes turned up. Two episodes depicting the first-generation Jynx have been pulled from rotation in the US (see that article for more details), though "Holiday Hi-Jinx" is still available on videocassette and DVD if you look closely enough. Clip Show episodes in later seasons were skipped because, really, who wants to watch a Pokémon clip show?
To add to this list, there were four episodes from Pokémon Advanced, one of them being Wattson's Gym battle, where they only aired twice overall. This was after the massive three-month hiatus before the next season began after these episodes aired. Though it's considered "missing" for a completely different reason.
And the two-part episodes in the Best Wishes! series that would finally introduce Team Plasma. According to some previews and Word of God, a lot of scenes showed a city being severely damaged. Then the 2011 Japan earthquake happened, and you have to take out these episodes from the grill. The producers promised that they will in fact air sometime, most likely re-edited and re-written to fit into a different time frame all together.
Nope. They now meet for the first time in the 'Season 2 Episode N' episode "Team Plasma's Pokémon Power Plot".
Another episode (revolving around Cilan fishing) was removed. It was originally made to set up the arc in which Bianca joins the group and Iris catching Emolga. When the episode aired, it was edited to retcon the episode's placement in the story, and the ending was changed to have Bianca leave the group.
In Japan only, the "Pikachu and Pichu" short ended up getting pulled from circulation in 2009 out of shame when narrator Noriko Sakai's drug scandal leaked out. The other option was re-recording the narration with another seiyuu.
Cowboy Bebop's first run on American TV happened almost immediately after 9/11note Well, most of it. Bebop began its Cartoon Network run in August 2001, and five episodes made it to air before network execs lowered the banhammer, leading to the following episodes being pulled:
"Sympathy for the Devil": The only 9/11-related reason behind banning this episode would be the man falling out of the window of a giant skyscraper and the Enfant Terrible getting trapped in a fire. Mostly, this episode was pulled because Adult Swim was just starting out and a lot of CN censors were worried about how people (who were already vulnerable and mad and grieving from the 9/11 attacks) would react to the climax of Spike shooting the boy between the eyes. When the episode finally aired, the climax was shown, but the bullet wound in the kid's head was digitally removed.
"Waltz For Venus": Now here's an episode with a more justified reason as to why it would be pulled following the 9/11 attacks. The beginning showed a Venus airliner getting hijacked (with Spike and Faye dispatching the would-be terrorists). When it was allowed to air months later, the beginning was left intact, but there was one strange edit: Faye bursts in on a man having anal sex with another man and holds the man on top at gunpoint. The man on the bottom is digitally removed, making it look like the man on top was humping his pillow (or an invisible man, as the censors did nothing to mute out the second man's voice, despite erasing him entirely).
"Cowboy Funk": Another episode with a more justified reason as to why it would be banned following 9/11. The episode centered around Spike trying to stop a terrorist called "The Teddy Bear Bomber" who targets large buildings. Nothing was done to change the plot when the episode finally aired (though the costume party sequence digitally altered the marijuana leaf on Jet's hippie T-shirt into a peace sign. It's actually one of CN's better and less obvious digital editing jobs).
The 19th episode "Wild Horses" was banned for a time after the Columbia space shuttle blew up. In the Remix collection, the space shuttle is renamed Challenger in that particular episode, which, if you think about it, really isn't that much better.
The finale of Excel♥Saga was never broadcast in Japan, and many other markets, because it was intentionally made too indecent for broadcast. Even the length of the show (a full minute too long) was unsuitable for broadcast.
Moetan's sixth episode, "The First Date", never aired for "various reasons". Until it hits DVD, these reasons have yet to be seen.
The "various reasons", given the evidence, appear to be "hype up sales for the DVDs." It worked, at least.
Whenever the original Astro Boy series is shown in Japan, the episodes are not from the original recordings, but are actually redubbed from the American edits of the episodes. This is because all original records of the series have been destroyed, because of financial reasons. Long story short: the masters were destroyed by NBC, who hadn't the room to retain them; when they offered to return them to Mushi Productions, Mushi — which was going through bankruptcy at the time — told them they were unable to accept them back and to just do whatever they normally did with unwanted masters. In fact, the practice of destroying copies, line arts, voice recordings or never-aired episodes was very common prior to the early 80's - God knows how much priceless original material has been destroyed.
One episode never aired in Japan at all because series creator Osamu Tezuka hated it so much he had the master destroyed. As it turned out, though, a copy of the master had already been sent to America for dubbing. Only the dubbed version was ever aired, and in the 1990's was even released on VHS as "Astro Boy: The Lost Episode".
For unknown reasons, the first two episodes of the 1982 Astro Boy remake were cut down into one single episode. Because all of the material about the creation of Atlas was cut, it made subsequent episodes about Atlas (some of which actually contained flashbacks to the cut material) somewhat baffling. It was only when the original episodes were released in subtitled form on DVD that most English-speaking fans finally understood Atlas' origins.
They actually originally aired together uncut as a one-hour special, but when shown in re-runs, this special was cut down to a normal-episode length. This is the only version of the dub of those episodes that exists in any usable condition.
An episode of the anime Ghost Stories was banned before it even aired in Japan, due to complaints from viewers about the Kuchisaki-Onna, based off a Japanese folktale, being insensitive to those with cleft palate disorder (as in the myth, she had a deformed mouth). The episode has never been released to DVD or broadcast anywhere, as a result of this (though considering what the English dub could have done with material like that, perhaps it's for the best).
Yoshiyuki Tomino had episode 15 of Mobile Suit Gundam ("Cucuruz Doan's Island") removed from both broadcasts and DVD / Bluray collections. The reasons cited are particularly Off Model animation and an unspecified beef Tomino had with the episode's director (all he'll say on the matter is "He knows what he did.")
For the US broadcast, the penultimate episode ("Space Fortress A Baoa Qu") was never aired, because Cartoon Network took the show off the air two episodes from the end due to the events of 9/11note Though many fans suspect that this was just a convenient excuse CN used to get out of their contract when the show performed poorly. The final episode ("Escape") was eventually run as part of New Year's Evil, a special marathon celebrating the villains of Toonami.
Nippon's "Grimm's Fairy Tale Classics" did have dubs for all of the episodes, but many were unaired in the U.S., or were pulled from reairing:
Bluebeard opens up with a man impaling his wife with a sword, and the climax of the whole story is the heroine (the man's seventh wife) finding the mutilated corpses of the previous wives. There were also magic roses that turned into blood.
The Crystal Ball focuses on a decaying old witch who imprisons a beautiful princess in her castle, and every night performs a demonic ritual where she bites said princess, and drains all her blood. This restores her youth for about a day, and the princess is left a decaying corpse, but regenerates in about a second. What makes it worse is that this happens every night.
This episode actually aired, but was never released. The dubbed version cut out the biting scenes, and had the witch use her magic to make the princess switch ages with her.
The Iron Stove and The Water Witch featured attractive, scantily-clad female villains, and went unaired in the U.S.
Godfather Death has a lot of on screen deaths.
There are missing chapters of a manga version of Batman from the 1960's.
Various hentai have missing episodes that don't make it to overseas releases. This is usually due to the presence of underage female characters who can't be explained or excused as actually being of legal age. See episode 2 of The Maiden Diaries, among others.
The Transformers Energon episode "Scorponok's Scars" was not only never shown in the west, but never even dubbed into English. The episode is important to the plot, and there's nothing particularly objectionable about it, so its absence is a complete mystery.
The fact that "Scorponok's Scars" is the English title of the episode "Return! Our Scorponok" just makes it that much more confusing.
Several episodes of Robots in Disguise were only aired once in the US or not at all due to September 11th.
The series premiere was three days before 9/11. The actual episode has not been re-run since due to a scene of Megatron smashing through a skyscraper... though in his Giant Hand mode instead of his Jet mode.
Code Geass had two Clip Show "half" episodes, outright labeled X.5; the staff openly admitted that they threw together these episodes to give them some "breathing room" because they weren't as far ahead in their scripts as most anime are. Bandai Entertainment didn't even bother dubbing these episodes for the American release, resulting in a couple of Missing Episodes that nobody will miss all that much.
International releases of the Rurouni Kenshin anime are missing two episodes that only aired during the initial Japanese TV broadcast. They were both clip shows that mixed episode footage with live action shots of plushies of the show's characters bridging the sequences.
Also, while it is available in the Media Blasters release, the last episode (95) was not licensed by Sony; which means that countries who based their dubs off that version (read: pretty much every country outside North America) never aired it.
One episode of Super Dimension Fortress Macross was briefly literally missing, as in a courier accidentally left the master reels of the finished episode on a train. Fortunately, they were able to recover the film, rather than have to reshoot the episode all over again.
The episode "Someday in the Rain" from The Melancholy of Haruhi Suzumiya (written by the original creator) was adapted to prose form in an issue of The Sneaker, but so far has not been included in any volume of the novels.
The 13th episode of Green Green is missing from the North American DVD release due to its graphic sexual nature.
The entire final season of Yu-Gi-Oh! GX was "lost" to American viewers, leaving the series to end on the depressing note of Jaden/Judai never returning from the alternate dimension.
The Yu-Gi-Oh! 5Ds dub skipped about a dozen episodes, jumping from Yusei's duel with Placido straight to the setup for the duel with Team Ragnarok and skipping over the Crimson Devil arc as well as the duel with Team Taiyo. This was followed up by 4Kids cutting the rest of the series after the duel with Aporia, meaning that the whole storyline with the Arc Cradle was cut alongside finding out who ZONE really was, and the final duel between Yusei and Jack was also removed due to this.
Sonic X had an entire season produced, yet it never aired in Japan. It was produced specifically for the 4Kids dub, even though TMS did actually have the voice actors return to voice the characters for that season. The 4Kids dub had a lot of scenes missing, and it remained like this until the uncut, uncensored versions were released on DVD in Japan, finally introducing the missing season to the show's home country.
The Hungarian, Romanian and Polish broadcast of Transformers Cybertron was all about this. For starters, the pilot episode was out-right omitted from the start. The series went on until about episode 16, after which the whole thing was constantly repeated multiple times. Finally, Cartoon Network got a hold of the rest of the series, and it aired further, before all of a sudden stopping at some point during the final arc. It went on to be repeated again, this time including the pilot. However when only a handful of episodes were left, guess what? The 1 year run of the show had come to an end, meaning it had to be pulled off the screen with only the last few episodes missing. The show was never re-aired or released on DVD.
At least with regards to Hungary, the show has been picked up again by another cartoon station and has aired beginning from April '14. So after almost a decade, those remaining episodes have seen the light of day, even if with a new dub.
Again from Hungary, both Dragon Ball Z and InuYasha have had a very troubled past, as originally neither series got to be aired in their entirety, nor have they been released fully on VHS tapes or DVD's. The reasons for this are difficult to decipher, and tons of Urban Legends have come into being because of them. However the real reason goes along the following lines: one of the country's main commercial TV stations, RTL Klub, had exclusive rights to airing the shows. Due to their violent nature, however, they were forced to push up the rating to the whopping 18+ (changed to 16+ in 2002, to no effect) age-range. The channel started protesting, which eventually lead to a lawsuit. Long story short, RTL decided to just cancel the shows, as a late night time-slot would have destroyed the ratings. The regular DB Z schedule was cut off after episode 121, but the late night airings didn't work out, and the series was canceled after that. Eps 122-137 came out on VHS some time later, but that was it. Animax also held broadcast rights for InuYasha, but only for episodes that had already been shown on RTL. And, as their luck would have it, the final 63 episodes have never been aired.
After the broadcasting rights to DB Z had expired, a fan undertaking purchased almost the entire dub, which then got leaked to the internet — granted, it was based on the badly translated and censored French version, but that's better than nothing. Only episodes 227-231 were still missing. Further, in 2012, another channel called Viasat6 picked up the series again, so after a 14 year wait, the post-121 episodes have finally been shown on TV for the first time, including the five "lost" episode dubs which haven't been seen anywhere priorly. The same can't be said for InuYasha — all episodes of the base-series were dubbed, but the missing ones have never been released anywhere.
Yu-Gi-Oh! GX has started airing in February '14, again courtesy of Viasat6 and their new dub, which will cover the entire series this time. Sadly, it's based again on the American cut, which was unfinished to begin with.
Sazae-san has only aired most of its episodes once, and never released them to home video. It was due to a request the creator made before her death. But during the 40th anniversary show, they aired some 1970's episodes, which is why it was a special event.
Another hard to find thing about Sazae-san is a Running Gag that appeared at the end of each episode from 1969 to 1991, in which Sazae would toss a bean or rice cake in the air and would catch it in her mouth at the end of each show. The stunt was imitated by viewers. In 1990, a child choked to death doing this, and just like the Hawaii Five-0 episode "Bored She Hung Herself" (which was also banned when someone in Real Life tried to imitate the stunt shown on TV, though Hawaii Five-O's didn't involve eating tossed food), it vanished off the face of the earth, and was replaced with a rock-paper-scissors game between Sazae and the viewers at home.
After that whole defamation controversy, add Gintama episode 232 to the list; also counts as an invertedNo Export for You because Crunchyroll had already uploaded the episode on their site before the controversy and continued streaming it for several weeks after it had been pulled in Japan.
The third episode of Lupin III (Red Jacket), "To Be or Nazi Be",note "Hitler's Legacy" was not broadcast by [adult swim] (even though the next-ep preview at the end of episode 2 still mentioned it), and had its release delayed until the fifth DVD volume, due to adventures and humor involving Those Wacky Nazis. This made preexisting Lupin III fans extremely unhappy, and may have contributed to the show's poor performance in America, thus becoming a small-scale Franchise Killer (nothing was licensed for a few more years afterwards, and those new licenses that have come up afterwards were sporadic and typically picked up by a smaller company called Discotek Media).
When Magical DoReMi was brought to the United States, episode 30 was skipped because it had religious references and kids walking around unsupervised in a graveyard.
Korea had a lot of Doremi episodes skipped in their dub. Episodes 22, 27, 29, 30, 33, 41 and 47 of Season 1 were skipped, episodes 10, 11, 13, 14, 24, 29, 35, 39 and 45 of Sharp were skipped, episodes 8, 9, 13, 15, 29, 33, 40, 41 and 46 of Motto were skipped, and episodes 19, 23 and 29 of Dokkan were skipped. The only season which din't skip any episodes was Na~i~sho.
InuYasha had 11 episodes skipped in Latin America (or, well, at least in Brazil): first were the two-parters "The Woman Who Loved Sesshoumaru" (133-134) and "The Tragic Love Song of Destiny" (147-148); apparently Televix (the company who distributed the anime around those parts) didn't license them due to they being a separate license (that is, they were considered television specials, not episodes). Then the last seven episodes went unaired, for no particular reason, leaving viewers hanging.
The last two episodes of .hack//SIGN weren't broadcast on US television. There wasn't anything objectionable in the episodesnote they were practically filler (one featured Mimiru interacting with a character that is run by three players; the other featured everyone just hanging out at a big party)., the distributors just didn't want fans to be able to record every episode and make a "complete box set".
Actually, this is part of a common practice in Japan, of releasing bonus episodes made specifically for the DVDs. The episodes were never part of the Japanese broadcast, either, and were only available on the Japanese home media release as well. More appropriate to this trope would be episode 14, Evidence, a clip show which was skipped on both the Japanese and US releases, despite being broadcast in both countries. The episode was eventually included as a bonus episode on the final volume of each set.
Mega Man NT Warrior, ShoPro's and Kids' WB!'s clumsiest English anime release. In the midst of multiple episode shufflings (yes, plural) and cancelled airings, seven episodes went unaired on KidsWB; and out of those, four were excluded completely, international airings and DVD releases included (they were all pointless but ultimately harmless filler). The Axess dub similarly also skipped 4 episodes worldwide, plus one that was dubbed, and did air in other countries, but not on KidsWB.
Despite being aired in the UK and clips from the episode were used in character spots, the Tenchi Muyo! special, Space Police Mihoshi's Space Adventure was never aired in the US. For good reason, too, including three of the characters crucified, a rape attempt and Pretty Sammy's transformation baring more skin that most magical girls should.
Before its highly successful 1979 anime and still popular 2005 successor, Doraemon had its first attempt at an anime series back in 1973. In contrast to the major hit the second series would become, the Doraemon of 1973 brought in poor ratings and finished its run after only six months. The fact that the two creators of the manga actively loathed the show didn't help at all. Eventually, a studio fire destroyed most of the master tapes which had the episodes on them, effectively making this not an example of Missing Episode, but Missing Series. Whatever few (as in, VERY few) episodes that still remain are sometimes shown at fan conventions, but other than that, there is no 1973 Doraemon anime to speak of. Kind of creepy to think about.
All the manga chapters that had the character Gachakko note A female robot duck featured early in the manga's run who pestered Doraemon and Nobita. were never reprinted due to the creators' eventual dislike towards her.
Chapter 83, the infamous "lost chapter" of Berserk, was never reprinted due to the author believing it gave away too much of the plot too soon.
In the English and German dubs of Attack No. 1, three episodes were not translated, due to "inappropiate content". These however are included as bonus on the German DVD sets.
Episode 33 of Oyako Club was unaired for unknown reasons.
The last US DVD volume of SD Gundam Force's first season went out of print and was mysteriously not reprinted with the other 8, resulting in an unresolved cliffhanger for those who didn't pick it up while it was available.
The footage to the previews of episodes 25, 27, and 28 of Esper Mami were destroyed. The audio to them survives and were included on a special DVD.
Abunai Sisters: Koko & Mika is generally regarded as one of the worst anime ever made. (For some reason, Production I.G. were behind it.) It aired on a subscription-only TV channel in Japan (with an English dub - subtitled in Japanese) for supposedly 10 episodes. Only two episodes were ever released on DVD, and have been uploaded to the Internet. The other eight episodes are presumably still locked away in the archives of the anime studio or the TV station, so unless you ever find somebody in Japan who recorded the episodes, chances are they aren't going to ever be taken out of the vaults.
Episode 48 of the English-dubbed 2001Cyborg009 series was this for the longest time, until a rip from an Australian Toonami broadcast surfaced. The "Yomi Group" recap and the alternate-universe "God's War" OVA arc were also dubbed, but never aired in the US and remain near-impossible to find, other than fans' accounts of them having aired overseas.
